Disclosed is a turn-over type dust-free automatic bag-breaking and feeding station, comprising: a frame (8); a bag-breaking compartment (5) fixedly arranged on the frame (8); a dust removal device, which is connected to the upper portion of the bag-breaking compartment (5); and a discharging device, which is connected to the lower portion of the bag-breaking compartment (5), wherein both the dust removal device and the discharging device are in communication with the bag-breaking compartment (5); a filter plate (12) is provided between the discharging device and the bag-breaking compartment (5); one end of the bag-breaking compartment (5) is provided with a feeding port (5-1), and the other end of the bag-breaking compartment (5) is provided with a waste bag recovery port (5-3); a feeding platform is provided at the feeding port (5-1) of the bag-breaking compartment (5); the filter plate (12) is obliquely arranged downwards from the feeding port (5-1) end of the bag-breaking compartment (5) to the waste bag recovery port (5-3) end of the bag-breaking compartment (5); and the end in the bag-breaking compartment (5) that is close to the feeding platform is provided with a bag-breaking device, the end in the bag-breaking compartment (5) that is away from the feeding platform is provided with a manual bag-shifting device, and a side wall of the bag-breaking compartment (5) is provided with an observation window (11). By means of the rotation of the manual bag-shifting device, a material bag can be turned over so as to clear loose material in a broken bag more thoroughly and prevent clogging when a waste bag is discharged.
A: Disclosed is a plastic bag vending mechanism, comprising a cabinet (101), a bag storage bin (301), a bag suction arm (401), an air pump (502) and a numerical control system. A cabinet door (201) on the front of the cabinet (101) can be opened for replenishment. A lower side of the cabinet door (201) is provided with a bag outlet (202). The bag storage bin (301) stores a vest-shaped plastic bag (304). The bag suction arm (401) is provided on the bag storage bin (301). The bag suction arm (401) is composed of an electromechanical member, a photoelectric sensor and a suction cup (402). The suction cup (402) is connected to the air pump (502) via an air pipe, and a negative air pressure generated by the air pump (502) enables the suction cup (402) to suck up the plastic bag (304) on the bag storage bin (301). The electromechanical component delivers the plastic bag (304) from the bag outlet (202), such that a customer can take the plastic bag (304) by himself/herself. A numerical control electronic system is provided inside a case. The numerical control system can communicate with a cashier system and can receive related instructions from external devices, such as the cashier system, to control the plastic bag vending machine to carry out a corresponding action.
B: A late-stage drying recycling device for color master batch, comprising a recycling box body (1). One end of the recycling box body (1) is provided with a feeding port (2), and the other end thereof is provided with a discharging port (3); a partition plate (4) inclined from the feeding port (2) to the discharging port (3) is provided in the recycling box body (1); the partition plate (4) partitions the recycling box body (1) into a recycling cavity (1-1) and an equipment cavity (1-2); the equipment cavity (1-2) is provided with at least three jacking devices (5) sequentially along the direction from the feeding port (2) to the discharging port (3); strip-shaped through grooves (7) used for allowing jacking plates (6) of the jacking devices (5) to pass through are formed in the partition plate (4); the surface of the partition plate (4) is provided with a covering supporting layer (8); the upper end portions of the jacking plates (6) are fixedly connected to the lower side surface of the covering supporting layer (8); and a cold air outlet (9) is formed in the recycling cavity (1-1). The device has the advantages that the dried color master batch can be fully cooled, and the safety of operators is guaranteed.
C: An environment-friendly fiber machine, comprising a fiber machine body (1). The fiber machine body (1) comprises a feeding apparatus (2), a grinding apparatus (5), a dust removal apparatus (6), and a water circulation system; the water circulation system comprises a water tank (8), a sprayer (3), and a water collection channel (11); the top of the fiber machine body (1) is provided with the feeding apparatus (2); the bottom of the feeding apparatus (2) is connected onto the grinding apparatus (5) provided at the upper side of the fiber machine body (1); the top of the grinding apparatus (5) is provided with the sprayer (3); a filter screen (14) is provided in the fiber machine body (1) below the grinding apparatus (5); a conveyor belt (12) is provided below the filter screen (14); one end of the conveyor belt (12) is provided with a discharge port (13), and the end of the conveyor belt (12) opposite to the discharge port (13) is provided with a motor (10); the water collection channel (11) is provided under the conveyor belt (12). By means of the provision of the grinding apparatus (5), the dust removal apparatus (6), and the water circulation system, the environment-friendly fiber machine solves the problems of environmental pollution and resource waste caused during fiber processing and improves environmental protection.
D: A bag-breaking machine for breaking renovation waste, the bag-breaking machine comprising two sets of rollers (1, 2) which are horizontally arranged and rotate in opposite directions. Meshing tooth-shaped structures (5) which are arranged at intervals are independently arranged on each set of rollers (1, 2), and the two sets of meshing tooth-shaped structures (5) are configured identically and arranged in a staggered manner; rotating shafts of the two sets of rollers (1, 2) are in transmission connection with variable-frequency speed reduction devices (3, 4); and the variable-frequency speed reduction devices (3, 4) are used for adjusting the speed of the rollers (1, 2).
