Description

Technical Field

[0001] This utility model relates to the field of plastic sheet processing technology, and in particular to a plastic sheet extrusion traction device. Background Technology

[0002] Plastic sheets are sheets made from plastic raw materials. The main components include high molecular polymers, such as synthetic resins, and may contain auxiliary materials such as fillers, plasticizers, stabilizers, lubricants, and colorants. These sheets have good practicality and are widely used in construction, chemical and other fields. They have properties such as wear resistance, vibration resistance, corrosion resistance, recyclability, high strength, aging resistance, water resistance, and moisture resistance.

[0003] During the production and processing of plastic sheets, traction devices are typically used for conveying to ensure that the extruded or calendered plastic sheets pass smoothly and evenly through the production line. In existing technologies, most plastic sheets are simply conveyed using traction devices. However, during this process, because there are no positioning devices on either side of the plastic sheets, they may tilt to the left or right or deviate from the track as the conveyor travels. Deviations in the conveyor can cause accidents or damage to equipment, rendering the technology impractical.

[0004] Therefore, it is necessary to design a plastic sheet extrusion traction device to address the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a plastic sheet extrusion traction device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A plastic sheet extrusion traction device includes a base plate. A double-headed screw is rotatably mounted on the upper surface of the base plate via a movable frame. A motor connected to the double-headed screw is fixedly mounted on the outer wall of the movable frame. Two movable sleeves are threadedly mounted on the outer wall of the double-headed screw via a limiting mechanism. A first connecting frame is fixedly mounted on the upper surface of each of the two movable sleeves. A second connecting frame is rotatably connected inside each of the two first connecting frames via a connecting mechanism. A traction device body is mounted on the upper surface of the two second connecting frames. Two connecting plates are fixedly mounted on the outer walls of both sides of the traction device body. A limiting plate is fixedly mounted on the upper surface of the base plate via a stabilizing mechanism. Electric push rods are fixedly mounted on the outer walls of both sides of the traction device body via fixed plates. Positioning frames are fixedly mounted on the telescopic ends of the two electric push rods. Multiple positioning rollers are rotatably mounted inside each of the two positioning frames. A cooling box and two pump bodies are fixedly mounted on the upper surface of the traction device body via a support mechanism. The inlet pipes of the two pump bodies extend into the cooling box.

[0008] Preferably, the limiting mechanism includes a limiting rod fixedly installed on the inner wall of the movable frame, the limiting rod sliding through the two movable sleeves.

[0009] Preferably, the connecting mechanism includes a connecting plate rotatably mounted inside the first connecting frame, and the end of the connecting plate is rotatably connected to the inside of the second connecting frame.

[0010] Preferably, the stabilizing mechanism includes multiple stabilizing rods fixedly installed on the upper surface of the base plate, the end of each stabilizing rod being fixedly connected to the bottom wall of the limiting plate, and each stabilizing rod slidingly penetrating the connecting plate.

[0011] Preferably, the support mechanism includes a support plate fixedly installed on the upper surface of the traction device body, and the cooling box and the two pump bodies are both fixedly installed on the upper surface of the support plate.

[0012] Preferably, spray pipes are fixedly installed on the outer walls of both pump body outlet pipes, and multiple nozzles are provided on the outer walls of both spray pipes.

[0013] The beneficial effects of this utility model are:

[0014] 1. By setting up components such as electric push rods, positioning frames and positioning rollers, the extension and retraction of two electric push rods can drive two positioning frames to move relative to each other. When the two positioning frames move, they can drive multiple positioning rollers inside to position the plastic sheet. This can prevent the plastic sheet from tilting to the left or right or deviating from the track during conveying, thus avoiding accidents or equipment damage caused by the plastic sheet running off track.

[0015] 2. By setting up components such as a movable sleeve, a first connecting frame, and a second connecting frame, while the two movable sleeves move, the first connecting frame can drive the second connecting frame to move through the cooperation of the connecting plate. With the cooperation of the two second connecting frames, the traction device body can be driven to move up and down. This enables the traction and conveying of plastic sheets of different sizes and thicknesses, avoiding bending and breakage of plastic sheets of different sizes when they fall into the traction device body.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A plastic sheet extrusion traction device includes a base plate 1. A double-headed screw 3 is rotatably mounted on the upper end face of the base plate 1 via a movable frame 2. A motor 4 connected to the double-headed screw 3 is fixedly mounted on the outer wall of the movable frame 2. Two movable sleeves 6 are threadedly mounted on the outer wall of the double-headed screw 3 via a limiting mechanism. The limiting mechanism includes a limiting rod 5 fixedly mounted on the inner wall of the movable frame 2. The limiting rod 5 slides through the two movable sleeves 6 and can limit the movement of the two movable sleeves 6, so that the two movable sleeves 6 can only move axially along the outer wall of the double-headed screw 3.

[0024] Two movable sleeves 6 are each fixedly mounted with a first connecting frame 7 on their upper surfaces. The two first connecting frames 7 are each rotatably connected to a second connecting frame 9 through a connecting mechanism. The connecting mechanism includes a connecting plate 8 rotatably mounted inside the first connecting frame 7. The end of the connecting plate 8 is rotatably connected to the inside of the second connecting frame 9. The upper surfaces of the two second connecting frames 9 are jointly mounted with a traction device body 10. Two connecting plates 11 are fixedly mounted on the outer walls of both sides of the traction device body 10.

[0025] A limiting plate 13 is fixedly installed on the upper surface of the base plate 1 by a stabilizing mechanism. The stabilizing mechanism includes multiple stabilizing rods 12 fixedly installed on the upper surface of the base plate 1. The end of each stabilizing rod 12 is fixedly connected to the bottom wall of the limiting plate 13, and each stabilizing rod 12 slides through the connecting plate 11.

[0026] Electric push rods 15 are fixedly installed on both sides of the outer wall of the traction device body 10 through fixing plates 14. Positioning frames 16 are fixedly installed on the telescopic ends of the two electric push rods 15. Multiple positioning rollers 17 are rotatably installed inside the two positioning frames 16. The positioning rollers 17 are rollers used to support and position the conveyor belt. Their main function is to maintain the correct position of the conveyor belt and avoid skewing or running off course.

[0027] A cooling box 19 and two pump bodies 20 are fixedly installed on the upper end face of the traction device body 10 by a support mechanism. The support mechanism includes a support plate 18 fixedly installed on the upper end face of the traction device body 10. The cooling box 19 and the two pump bodies 20 are both fixedly installed on the upper end face of the support plate 18. The inlet pipes of the two pump bodies 20 extend into the interior of the cooling box 19. Spray pipes 21 are fixedly installed on the outer wall of the outlet pipes of the two pump bodies 20. Multiple nozzles are opened on the outer wall of the two spray pipes 21.

[0028] When this utility model is in use, the extruded plastic sheet falls into the traction device body 10 for traction and conveying. During the traction and conveying process, the extension and retraction of the two electric push rods 15 can drive the two positioning frames 16 to move relative to each other. When the two positioning frames 16 move, they can drive the multiple positioning rollers 17 inside to position the plastic sheet. This can prevent the plastic sheet from tilting to the left, right or deviating from the track during conveying, which would cause accidents or damage to the equipment due to the plastic sheet running off track.

[0029] Two electric actuators 15 can be positioned according to the size of the sheet, increasing the traction and conveying efficiency of the plastic sheet. At the same time, during traction and conveying, coolant can be pumped from inside the cooling tank 19 through the inlet pipes of the two pump bodies 20. The pumped coolant enters the spray pipe 21 through the outlet pipe. The spray pipe 21 then sprays the plastic sheet with the cooperation of multiple nozzles, thereby achieving rapid cooling and molding of the plastic sheet.

[0030] When traction and conveying plastic sheets of different sizes and thicknesses, the motor 4 drives the double-headed screw 3 to rotate. When the double-headed screw 3 rotates, it can drive the two moving sleeves 6 to move through cooperation with the limit rod 5. At the same time as the two moving sleeves 6 move, the first connecting frame 7 can drive the second connecting frame 9 to move through cooperation with the connecting plate 8. With the cooperation of the two second connecting frames 9, the traction device body 10 can be driven to move up and down. This can realize the traction and conveying of plastic sheets of different sizes and thicknesses, and avoid the bending and breakage of plastic sheets of different sizes when they fall into the traction device body 10, thereby reducing the waste of plastic sheets after molding.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
