Description

Technical Field

[0001] This utility model relates to the technical field of plastic film preparation equipment, and in particular to a mixing machine for plastic film production. Background Technology

[0002] The main component of polyethylene plastic is polyethylene, which is a thermoplastic resin obtained by polymerizing ethylene. The raw materials used in the production of polyethylene film are generally composed of several different polyethylene granules. Before preparing the raw materials, the polyethylene granules of various compositions are added to a mixer in a certain proportion. The mixer mixes the various polyethylene granules evenly, and then these mixed granular raw materials are conveyed to a blown film machine for melting.

[0003] Currently, in existing mixing machines, workers pour different polyethylene granules into the mixing chamber of the mixing machine when mixing raw materials. The motor of the mixing machine drives the stirring components to mix the various polyethylene granules evenly. However, after mixing the raw materials, workers need to take the raw materials out of the chamber and then transport them to a designated location to facilitate adding the mixed raw materials to the next process. This process requires a lot of labor and is not very efficient. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mixing machine for plastic film production, which solves the problem that existing mixing machines are not convenient for transferring the mixed raw materials.

[0005] According to an embodiment of this utility model, a mixing machine for producing plastic film includes: a mixing box, a top cover, a stirring assembly, and a motor. The interior of the mixing box is a mixing hopper, and the top of the mixing box is open. The top cover is located on the top of the mixing box. The stirring assembly is rotatably mounted inside the mixing box. At least three supports are evenly arranged at the bottom of the mixing box. Mounting plates are provided on the side walls of the supports. The motor is fixed to the top of the mounting plates, and the output end of the motor is connected to the stirring assembly. A base is provided at the bottom of each support, and a wheel is provided at the bottom of each base. An anti-slip component is provided on the side wall of each base. A discharge cylinder is provided on the side wall of the mixing box, and an opening and closing component for opening and closing the discharge cylinder is also provided on the side wall of the mixing box.

[0006] Compared with the prior art, this utility model has the following beneficial effects: By setting wheels and anti-slip components at the bottom of each support, the anti-slip components can restrict the wheels from rolling on the ground when the mixing machine for plastic film production is mixing raw materials. After the raw materials are mixed, the anti-slip components can be controlled to no longer restrict the wheels, and then the mixing machine can be pushed on the ground. This allows the mixing machine to be transported to the feeding port of the next process in the plastic film production process. Then, the opening and closing components are controlled to open the discharge cylinder, and the mixed raw materials are discharged from the discharge cylinder. Then, the mixed raw materials can be added to the next process. In this way, the number of steps that require workers to carry the mixed raw materials is reduced, which reduces the workload of workers. At the same time, by moving the mixing machine as a whole, the efficiency of transporting mixed raw materials is also improved.

[0007] Furthermore, the bottom of the mixing hopper is inclined, and the discharge cylinder is also inclined, with the discharge cylinder connected to the lower end of the bottom of the mixing hopper.

[0008] Furthermore, each of the aforementioned anti-slip components includes: a mounting block, a lead screw, and an anti-slip pad. The mounting block is fixed to the side wall of the base, the lead screw passes vertically through the mounting block, a mounting post is fixedly provided at the bottom end of the lead screw, the anti-slip pad is fixed to the bottom of the mounting post, the lead screw is threadedly connected to the mounting block, and a handle is provided at the top of the lead screw.

[0009] Furthermore, the opening and closing assembly includes a drive shaft, a closing plate, and a locking mechanism. The closing plate is rotatably disposed inside the mixing chamber via the drive shaft and is used to open and close the discharge cylinder. The locking mechanism is disposed on the side wall of the mixing chamber. One end of the drive shaft extends out of the mixing chamber, and the locking mechanism is used to lock the drive shaft. A rotating handle is provided at the end of the drive shaft located outside the mixing chamber.

[0010] Furthermore, the locking mechanism includes: a mounting base, a spring, a limiting pin, and a lever. The mounting base is fixed to the side wall of the mixing box. The end of the mounting base near the drive shaft is provided with a mounting groove. The limiting pin and the spring are both disposed in the mounting groove. The limiting pin is slidably connected to the mounting groove. Limiting grooves are symmetrically provided on both sides of the drive shaft. The limiting pin is inserted into the limiting groove under the elastic force of the spring. The side wall of the mounting base is provided with a sliding groove, which communicates with the mounting groove. The lever is slidably disposed in the sliding groove, and one end of the lever is fixedly connected to the side wall of the limiting pin.

[0011] Furthermore, a handle is provided on the top of the cover, and a rubber sleeve is fitted on the handle.

[0012] Furthermore, the mixing assembly includes: a mixing shaft, which is rotatably disposed at the bottom of the mixing hopper; the output end of the motor is fixedly connected to one end of the mixing shaft; and a plurality of mixing rods are disposed on the side wall of the mixing shaft.

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1 As shown in the figure, this utility model embodiment proposes a mixing machine for plastic film production, including: a mixing tank 1, a top cover 2, a stirring assembly, and a motor 6. The interior of the mixing tank 1 is a mixing chamber, and the top of the mixing tank 1 is open. The top cover 2 is located on the top of the mixing tank 1. The stirring assembly is rotatably mounted inside the mixing tank 1. At least three supports 3 are evenly arranged on the bottom of the mixing tank 1. The side walls of the supports 3 are provided with mounting plates 5. The motor 6 is fixed to the top of the mounting plate 5, and the output end of the motor 6 is connected to the stirring assembly. Each support... Each frame 3 has a base 25 at its bottom, and each base 25 has a wheel 4 at its bottom. Each base 25 has an anti-slip component on its side wall. The mixing box 1 has a discharge cylinder 7 on its side wall, and the mixing box 1 also has an opening and closing component for opening and closing the discharge cylinder 7. A handle 24 is also provided on the top of the end cover, which allows workers to remove the top cover 2 from the top of the mixing box 1 through the handle 24, thereby adding the raw materials from the top of the mixing box 1 into the mixing hopper. Furthermore, a rubber sleeve is also provided on the handle 24.

[0018] By installing wheels 4 and anti-slip components at the bottom of each support 3, the anti-slip components restrict the wheels 4 from rolling on the ground when the mixing machine is mixing raw materials. After the raw materials are mixed, the anti-slip components are removed, allowing the mixing machine to move on the ground. This allows the mixing machine to be moved to the feeding port of the next process in the plastic film production process. Then, the opening and closing components are controlled to open the discharge cylinder 7, and the mixed raw materials are discharged from the discharge cylinder 7. The mixed raw materials can then be added to the next process. This method reduces the number of steps that workers need to take to move the mixed raw materials, reducing the workload of workers. At the same time, by moving the mixing machine as a whole, the efficiency of transporting mixed raw materials is also improved.

[0019] Furthermore, the bottom of the mixing hopper is inclined, and the discharge cylinder 7 is also inclined, and the discharge cylinder 7 is connected to the lower end of the bottom of the mixing hopper, so that the raw materials in the mixing hopper can be discharged cleanly.

[0020] Specifically, each of the aforementioned anti-slip components includes: a mounting block 8, a lead screw 9, and an anti-slip pad 11. The mounting block 8 is fixed to the side wall of the base 25. The lead screw 9 passes vertically through the mounting block 8. A mounting post 10 is fixedly installed at the bottom end of the lead screw 9. The anti-slip pad 11 is fixed to the bottom of the mounting post 10. The lead screw 9 is threadedly connected to the mounting block 8. A handle 12 is provided at the top of the lead screw 9. When it is necessary to restrict the wheel 4, the lead screw 9 is rotated by the handle 12, causing the lead screw 9 to drive the mounting post 10 to move vertically downward, ultimately causing the anti-slip pad 11 at the end of the mounting post 10 to be in close contact with the ground. Under the action of the friction between the anti-slip pad 11 and the ground, the wheel 4 is restricted from walking on the ground. When it is necessary to release the wheel 4, the handle 24 is simply reversed. The anti-slip pad 11 is made of rubber material.

[0021] like Figure 2As shown, the opening and closing assembly includes a drive shaft 13, a closing plate 14, and a locking mechanism. The closing plate 14 is rotatably disposed inside the mixing chamber via the drive shaft 13. The closing plate 14 is used to open and close the discharge cylinder 7. The locking mechanism is disposed on the side wall of the mixing chamber 1. One end of the drive shaft 13 extends out of the mixing chamber 1. The locking mechanism is used to lock the drive shaft 13. A rotating handle 15 is provided at the end of the drive shaft 13 located outside the mixing chamber 1. Furthermore, the locking mechanism includes: a mounting base 16, a spring 17, a limiting pin 18, and a lever 21. The mounting base 16 is fixed to the side wall of the mixing box 1. The end of the mounting base 16 near the drive shaft 13 is provided with a mounting groove. The limiting pin 18 and the spring 17 are both disposed in the mounting groove. The limiting pin 18 is slidably connected to the mounting groove. The two side walls of the drive shaft 13 are symmetrically provided with limiting grooves 19. The limiting pin 18 is inserted into the limiting groove 19 under the elastic force of the spring 17. The side wall of the mounting base 16 is provided with a sliding groove 20, which communicates with the mounting groove. The lever 21 is slidably disposed in the sliding groove 20. One end of the lever 21 is fixedly connected to the side wall of the limiting pin 18. Furthermore, the lever 21 and the rotating handle 15 are not on the same vertical plane to prevent the lever 21 from interfering with the rotation of the rotating handle 15.

[0022] When adding or mixing raw materials, the end of the discharge cylinder 7 connected to the mixing hopper needs to be closed. The specific operation steps are as follows: the drive shaft 13 is rotated by rotating the handle 15, which drives the closing plate 14 to rotate, so that the closing plate 14 is in close contact with the bottom of the mixing hopper. At this time, the closing plate 14 is also in close contact with the end of the discharge cylinder 7 connected to the mixing hopper, thus closing the discharge cylinder 7. Specifically, an open or closed indicator can be set on one side of each of the two limiting grooves 19. When the limiting pin 18 is inserted into the two different limiting grooves 19 respectively, it means that the closing plate 14 closes or opens the discharge cylinder 7, which facilitates the operation of the operator. When the limiting pin 18 is aligned with the limiting groove 19 on the side wall of the drive shaft 13, the limiting pin 18 is inserted into the limiting groove 19 under the elastic force of the spring 17. At this time, the limiting pin 18 restricts the rotation of the drive shaft 13, thereby keeping the closing plate 14 in the open or closed state of the discharge cylinder 7.

[0023] Specifically, such as Figure 1 As shown, the mixing assembly includes: a mixing shaft 22, which is rotatably disposed at the bottom of the mixing hopper. The output end of the motor 6 is fixedly connected to one end of the mixing shaft 22. Specifically, one end of the mixing shaft 22 extends out of the mixing hopper and is fixedly connected to the output end of the motor 6. The mixing shaft 22 is dynamically sealed to the mixing box 1. Several mixing rods 23 are provided on the side wall of the mixing shaft 22. The output end of the motor 6 drives the mixing shaft 22 to rotate, thereby causing the mixing rods 23 on the side wall of the mixing shaft 22 to stir the raw materials in the mixing hopper and mix the raw materials evenly.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
