A mixing system for PC film raw material production

Abstract

A mixing system for PC film raw material production includes a feeding device and a mixing device. The feeding device includes a gantry crane, a discharge chute, and a tipping hopper. The tipping hopper is rotatably installed on one side of the discharge chute and located directly below the gantry crane. A ton bag fixing component is provided on the tipping hopper. The advantages of this invention are: during feeding, the ton bag is tilted to pour the raw material through the tipping hopper, saving time and labor, and can pour the raw material into the discharge chute at a uniform speed, effectively preventing the raw material from scattering; the raw material circulates repeatedly in the mixing hopper and mixing drum, which can quickly and evenly mix the raw material. At the same time, the protective filter screen shakes up and down during the mixing process, which can effectively prevent the raw material from clogging and ensure smooth discharge.

Description

Technical Field

[0001] This utility model relates to the technical field of PC film production equipment, specifically to a mixing system for PC film raw material production. Background Technology

[0002] PC film production raw materials are made by mixing and plasticizing resin and various auxiliary materials, then cutting them into pellets, and then melting and molding them in an extruder. The existing raw material preparation process has the following problems: During the feeding process, after the raw material ton bags are hoisted onto the hopper, the staff needs to manually control the tilting of the ton bags, which is time-consuming and labor-intensive, and it is easy for the raw materials to scatter outside the hopper; During the raw material mixing stage, because PC resin particles and PC recycled crushed materials are relatively light, they are prone to clogging in the mixing hopper, affecting the efficiency of feeding and mixing.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] As shown in the attached figure, the present invention includes a feeding device 1 and a mixing device 2. The feeding device 1 includes a gantry crane 6, a discharge chute 7 and a tipping hopper 8. The tipping hopper 8 is rotatably installed on one side of the discharge chute 7 and located directly below the gantry crane 6. A ton bag fixing component 9 is provided on the tipping hopper 8. The gantry crane 6 is equipped with an electric hoist. The ton bag is lifted and transported laterally into the tipping hopper 8 by the electric hoist. The ton bag fixing component 9 fixes the ton bag. Then the tipping hopper 8 flips over and slowly pours the raw material in the ton bag into the discharge chute 7.

[0024] The mixing device 2 includes a mixing barrel 20 and a mixing hopper 21. The lower side wall of the mixing barrel 20 is provided with a circulating mixing outlet pipe 23 and a discharge pipe 24, respectively. The bottom of the mixing barrel 20 is provided with a circulating feed pipe 25. The mixing hopper 21 is installed on one side of the mixing barrel 20 and communicates with the circulating feed pipe 25. The mixing hopper 21 is provided with a protective filter screen 26 that can be shaken up and down. The mixing barrel 20 is provided with a spiral conveying blade 27 coaxially. The top of the mixing barrel 20 is provided with a drive motor 28 that drives the spiral conveying blade 27 to rotate. The mixing hopper 21 is located below the discharge end of the feeding chute 7. Raw materials enter the mixing hopper 21 through the feeding chute 7, and then enter the mixing drum 20 through the mixing hopper 21. When the screw conveyor blades 27 rotate, they convey the raw materials entering the mixing drum 20 upwards. During mixing, the circulating mixing discharge pipe 23 is open, and the discharge pipe 24 is closed. When the raw materials are conveyed upwards in the mixing drum 20, they flow back from the circulating mixing discharge pipe 23 into the mixing hopper 21, and then enter the mixing drum 20 together with the raw materials in the mixing hopper 21. This cycle repeats to ensure the raw materials are mixed evenly. After mixing is complete, the circulating mixing discharge pipe 23 is closed, and the discharge pipe 24 is opened, allowing the raw materials to be discharged from the discharge pipe 24. During discharge, the screw conveyor blades 27 rotate, conveying the raw materials at the bottom upwards.

[0025] Furthermore, the bottom of the discharge chute 7 is provided with a chute support frame, and the tipping hopper 8 is rotatably mounted on the chute support frame via a pin. The chute support frame is provided with a pneumatic slide table 10 that drives the tipping hopper 8 to flip. The slider of the pneumatic slide table 10 is connected to the tipping hopper 8 via a connecting rod 11.

[0026] The pneumatic slide 10 moves linearly, and the bottom end of the tipping hopper 8 is tilted up and down by the connecting rod 11, thereby tipping the ton bag.

[0027] Preferably, the ton bag fixing assembly 9 includes an adsorption plate 12 and an air pump 13. The adsorption plate 12 is installed inside the tipping hopper 8 and has multiple sets of air holes at the bottom. The air pump 13 is installed outside the tipping hopper 8 and communicates with the multiple sets of air holes of the adsorption plate 12.

[0028] After the ton bag is placed on the tipping hopper 8, the lower surface of the ton bag, which is attached to one side of the tipping hopper 8, is adsorbed by the air holes of the adsorption plate 12, preventing the ton bag from sliding into the discharge chute 7 during the tipping process.

[0029] Furthermore, the adsorption plate 12 is provided with an anti-slip rubber layer 14, and the anti-slip rubber layer 14 has through holes corresponding to the air vents. The anti-slip rubber layer 14 can further enhance the anti-slip effect.

[0030] Furthermore, the protective filter 26 is located between the circulating mixing outlet pipe 23 and the circulating feed pipe 25, and both the circulating mixing outlet pipe 23 and the discharge pipe 24 are equipped with discharge valves. The protective filter 26 serves to prevent large foreign objects from falling into the mixing tank 20, while simultaneously ensuring that the incoming raw materials are evenly fed into the mixing tank 20.

[0031] Furthermore, one end of the protective filter screen 26 is hinged to the mixing hopper 21 by a pin, and the other end of the protective filter screen 26 is linked to the spiral conveying blade 27 by the drive rod 31.

[0032] Specifically, one end of the mounting shaft of the spiral conveyor blade 27 extends below the circulating feed pipe 25, and the frame of the mixing tank 20 is equipped with a drive shaft. The mounting shaft and the drive shaft are respectively equipped with a transmission gear 34 that cooperates with each other. The drive shaft is equipped with a drive cam 35 that controls the drive rod 31 to move up and down reciprocally.

[0033] The drive cam 35 is provided with a cam groove, and the drive rod 31 is provided with a roller that cooperates with the cam groove. When the drive cam 35 rotates, it drives the drive rod 31 to move up and down, thereby causing one end of the protective filter screen 26 to swing up and down.
