Description

Technical Field

[0001] This utility model relates to the technical field of traction devices for PS recycled plastic foaming production lines, and in particular to a traction device for a PS recycled plastic foaming production line. Background Technology

[0002] Recycled PS plastics refer to the process of reprocessing waste polystyrene plastic products into usable plastic granules or products through recycling, cleaning, melting, and remanufacturing. Its core principle is recycling, reducing resource waste and environmental pollution.

[0003] Existing PS recycled plastic foaming production lines use a suitable traction machine to transport the cooled plastic foamed sheets during production. The feed end of the traction machine is usually equipped with two limiting rubber rollers to limit the transport of the plastic foamed sheets. However, the limiting rubber rollers are adjusted independently during sliding adjustment. Therefore, the positions of the two rubber rollers at the feed end of the traction machine cannot be symmetrical. Consequently, the two rubber rollers cannot cooperate to limit the plastic foamed sheets when not adjusted, which can lead to the plastic foamed sheets shifting during transport. To address this issue, we provide a traction device for PS recycled plastic foaming production lines. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the two feed limit rollers of the traction machine used in a PS recycled plastic foaming production line cannot be conveniently and accurately adjusted, and to provide a traction device for a PS recycled plastic foaming production line.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a traction device for a PS recycled plastic foaming production line, comprising: a traction machine, a limiting mechanism provided on one side of the traction machine, the limiting mechanism including a fixed frame, a bidirectional threaded rod sleeved inside the fixed frame, a threaded block sleeved on the outer surface of the bidirectional threaded rod, two threaded blocks, the threaded blocks being threadedly connected to the bidirectional threaded rod, a circular plate provided at the top of the threaded block, a rotating rod sleeved inside the circular plate, a sleeve sleeved on the outer surface of the rotating rod, the sleeve being fixedly connected to the rotating rod, a rubber sleeve sleeved on the outer surface of the sleeve, the rubber sleeve being fixedly connected to the sleeve, a bearing being sleeved on the outer surface of one end of the rotating rod, a connecting mechanism provided inside the threaded block, the connecting mechanism including an mounting block, the mounting block being sleeved inside the threaded block, the mounting block being slidably connected to the threaded block, and the mounting block being fixedly connected to the circular plate.

[0006] In a preferred embodiment, the fixed frame is fixedly connected to the traction machine, the threaded block is sleeved inside the fixed frame, the threaded block is slidably connected to the fixed frame, the first bearing is placed inside the circular plate, the first bearing is fixedly connected to the inner wall of the circular plate and the outer surface of the rotating rod, a second bearing is sleeved on the outer surface of one end of the bidirectional threaded rod, the second bearing is placed inside the fixed frame, the second bearing is fixedly connected to the outer surface of the bidirectional threaded rod and the inner wall of the fixed frame, and a knob is provided at one end of the bidirectional threaded rod, the knob is fixedly connected to the bidirectional threaded rod.

[0007] In a preferred embodiment, an angled block is fitted inside the mounting block and the threaded block, and the angled block is slidably connected to both the mounting block and the threaded block. One end of the angled block is provided with a sliding block.

[0008] In a preferred embodiment, the sliding block is fixedly connected to the beveled block, the sliding block is sleeved inside the threaded block, and the sliding block and the threaded block are slidably connected.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This invention utilizes a limiting mechanism positioned at the feed end of a traction machine to restrict the movement of the foamed plastic sheet entering the machine, preventing deviation during transport. A bidirectional threaded rod drives two threaded blocks, allowing them to move simultaneously in opposite directions. This allows for simultaneous adjustment of the positions of the sleeves and rubber sleeves on top of the threaded blocks. The two sets of sleeves and rubber sleeves work together to limit the movement of the foamed plastic sheet. A connecting mechanism, used in conjunction with the limiting mechanism, facilitates easy connection and separation of the threaded blocks and the disc. This also allows for convenient replacement of worn rubber sleeves by the operator, ensuring both product quality and the precision of the limiting mechanism. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] like Figures 1-5As shown, this utility model provides a technical solution: a traction device for a PS recycled plastic foaming production line, comprising: a traction machine 1, a limiting mechanism 2 on one side of the traction machine 1, the limiting mechanism 2 including a fixed frame 21, a bidirectional threaded rod 22 sleeved inside the fixed frame 21, and a threaded block 23 sleeved on the outer surface of the bidirectional threaded rod 22, the number of threaded blocks 23 being two, the threaded blocks 23 being threadedly connected to the bidirectional threaded rod 22, a circular plate 24 on the top of the threaded block 23, a rotating rod 25 sleeved inside the circular plate 24, a sleeve 26 sleeved on the outer surface of the rotating rod 25, the sleeve 26 being fixedly connected to the rotating rod 25, a rubber sleeve 27 sleeved on the outer surface of the sleeve 26, the rubber sleeve 27 being fixedly connected to the sleeve 26, a bearing 28 sleeved on the outer surface of one end of the rotating rod 25, and a connecting rod 28 being provided inside the threaded block 23. The connecting mechanism 3 includes a mounting block 31, which is fitted inside the threaded block 23 and is slidably connected to the threaded block 23. The mounting block 31 is fixedly connected to the disc 24. The fixed frame 21 is fixedly connected to the traction machine 1. The threaded block 23 is fitted inside the fixed frame 21 and is slidably connected to the fixed frame 21. Bearing 1 28 is placed inside the disc 24 and is fixedly connected to the inner wall of the disc 24 and the outer surface of the rotating rod 25. Bearing 29 is fitted onto the outer surface of one end of the bidirectional threaded rod 22 and is placed inside the fixed frame 21. Bearing 29 is fixedly connected to the outer surface of the bidirectional threaded rod 22 and the inner wall of the fixed frame 21. A knob 201 is provided at one end of the bidirectional threaded rod 22 and is fixedly connected to the bidirectional threaded rod 22.

[0027] In this embodiment, a bidirectional threaded rod 22 is provided, which drives two threaded blocks 23 when rotating, allowing the two threaded blocks 23 to move simultaneously in opposite directions. This facilitates convenient and precise adjustment of the positions of the two sleeves 26 and the rubber sleeve 27, enabling the two sleeves 26 and the rubber sleeve 27 to limit the transmission of the plastic foam board with the cooperation of other components. A rotating rod 25 is also provided, positioned inside the circular plate 24. One end of the part is fitted with a bearing 28, which allows the rotating rod 25 to rotate more smoothly under the action of the bearing 28. This allows the sleeve 26 and the rubber sleeve 27 to rotate, ensuring that the plastic foam board is limited while reducing the contact friction between them. When the limiting mechanism 2 is installed, it is necessary to ensure that the symmetrical center plane of the fixing frame 21 coincides with the symmetrical center plane of the feed port of the traction machine 1. This allows the bidirectional threaded rod 22 to adjust the position of the sleeve 26 and the rubber sleeve 27 to match the actual use requirements.

[0028] Example 2

[0029] like Figures 1-5As shown, an angled block 32 is fitted inside the mounting block 31 and the threaded block 23. The angled block 32 is slidably connected to both the mounting block 31 and the threaded block 23. A sliding block 33 is provided at one end of the angled block 32. The sliding block 33 is fixedly connected to the angled block 32. The sliding block 33 is fitted inside the threaded block 23. The sliding block 33 is slidably connected to the threaded block 23. A limit rod 34 is fixedly connected to one side of the sliding block 33. The limit rod 34 is fitted inside the threaded block 23. The limit rod 34 is slidably connected to the threaded block 23. A spring 35 is fitted on the outer surface of the limit rod 34. A pull block 36 is provided at one end of the sliding block 33. The pull block 36 is fixedly connected to the sliding block 33.

[0030] In this embodiment, by setting a connecting mechanism 3, the threaded block 23 and the disc 24 can be easily installed and separated, and the aged rubber sleeve 27 can be disassembled and replaced. A mounting block 31 is set, and a slot is opened on the mounting block 31 to fit with the beveled block 32, so that the beveled block 32 can be engaged with the mounting block 31, so that the installed threaded block 23 and disc 24 can remain stable. At the same time, a spring 35 is set, and the spring 35 can be compressed to generate elastic force. The elastic force of the spring 35 can not only automatically reset the beveled block 32, but also keep the beveled block 32 and the mounting block 31 engaged tightly. At the same time, a limiting rod 34 is set, and the limiting rod 34 can be used to cooperate with the inner wall of the threaded block 23 to limit the spring 35, so that the spring 35 will not twist when compressed.

[0031] Working principle:

[0032] like Figures 1-5As shown, in use, the components such as the fixing bracket 21 in the limiting mechanism 2 can be properly installed first. Then, the circular piece 24 and the threaded block 23 are connected. At this time, the circular piece 24 drives the mounting block 31 into the interior of the threaded block 23. When the mounting block 31 slides inside the threaded block 23, it will squeeze the beveled block 32, causing the beveled block 32 to slide into the interior of the threaded block 23. When the beveled block 32 slides, it will compress the spring 35 using the sliding block 33. The spring 35 will gradually generate elastic force under the limitation of the limiting rod 34. When the mounting block 31 can no longer slide, the elastic force of the spring 35 will be released instantly, and the sliding block 33 and the beveled block 32 will be reset, so that the beveled block 32 is tightly engaged inside the mounting block 31. At this time, the circular piece 24 and the threaded block 23 will be in a stable connection state. Then, the positions of the two sleeves 26 and the rubber sleeve 27 can be adjusted according to the size of the produced plastic foam board. The knob 20 can be turned first. 1. The knob 201 drives the bidirectional threaded rod 22 to rotate. The bidirectional threaded rod 22, in cooperation with the bearing 29, drives the two threaded blocks 23 to move simultaneously in opposite directions until the sleeve 26 and the rubber sleeve 27 are in the appropriate positions to limit the movement of the plastic foam board. The rubber sleeve 27 will make slight contact with the plastic foam board. Without affecting the production quality of the plastic foam board, the plastic foam board will drive the rubber sleeve 27 and the sleeve 26 to rotate. The sleeve 26 and the rubber sleeve 27 can rotate smoothly with the cooperation of the rotating rod 25 and the bearing 28. If the aging rubber sleeve 27 needs to be replaced, the pull block 36 can be slid first. The pull block 36 drives the sliding block 33 and the bevel block 32 to slide, so that the bevel block 32 disengages from the mounting block 31. Then the disc 24 can disengage from the threaded block 23, so that the rubber sleeve 27 can be removed for easy replacement.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
