Description

Technical Field

[0001] This utility model relates to the technical field of polyethylene sheet production equipment, specifically to a transportation mechanism for polyethylene sheets. Background Technology

[0002] Polyethylene sheets are widely used in many fields due to their excellent impact resistance, good chemical stability, and good insulation properties.

[0003] After extrusion molding, polyethylene sheets are typically cut to standard sizes to ensure each sheet is the same size, meeting the needs of different customers. The cut sheets are then transferred from the cutting machine conveyor belt using a sheet adsorption device and stacked on a transfer pallet (placed downstream of the cutting machine conveyor belt). They are then transported to the grinding area for grinding and packaging. Currently, there is no dedicated transportation mechanism for transferring the polyethylene sheets stacked on the transfer pallet; all transfers are done manually (e.g., using handcarts). Manual transfer is time-consuming and labor-intensive. Furthermore, when the polyethylene sheets are large or heavy, transferring more sheets at once requires forklifts, but the limited space in the polyethylene production area makes forklift transport a safety hazard. Utility Model Content

[0004] In view of the shortcomings of the prior art, the present invention provides a transportation mechanism for polyethylene sheets.

[0005] The technical solutions to the above technical problems are as follows:

[0006] A transport mechanism for polyethylene sheets includes a base, a movable platform that moves along the base to place a transfer pallet, and a drive assembly that drives the movable platform to move along the base. The base has a slide rail, and the lower end face of the movable platform has several sliders that slide in cooperation with the slide rail. The base also has a first track and a second track, located on opposite sides of the slide rail. The lower end face of the movable platform also has several first roller assemblies and several second roller assemblies, located on opposite sides of the sliders. Each first roller assembly includes a first wheel frame and a first roller. The first wheel frame is fixedly connected to the movable platform, and the first roller is rotatably connected to the first wheel frame via a bearing. The first roller cooperates with the first track. Each second roller assembly includes a second wheel frame and a second roller, which cooperates with the second track. Both the first and second rollers are made of metal and are conical.

[0007] Furthermore, the drive assembly includes a driver, a drive gear, and a drive rack. The driver is mounted on the mobile platform, the drive gear is fixedly connected to the output end of the driver, and the drive rack is fixed on the base, with the drive gear and drive rack engaging.

[0008] Furthermore, an L-shaped baffle is provided on the upper surface of the mobile platform. The L-shaped baffle is fixed on the upper surface of the mobile platform, and the driver is fixed on the L-shaped baffle. A rubber block is provided on the radial end face of the L-shaped baffle.

[0009] Furthermore, several buffer blocks are provided at both ends of the base.

[0010] The beneficial effects of this invention are as follows: This invention uses a mobile platform to place a transfer pallet, enabling the transfer pallet to transfer more polyethylene sheets at once. The mobile platform is driven by a drive assembly, and through the cooperation of slide rails and sliders, as well as the action of the first and second roller assemblies, the mobile platform reciprocates on the base to achieve the transfer of polyethylene sheets. This invention avoids the time-consuming and labor-intensive problems of traditional polyethylene sheet transfer methods, avoids the safety hazards of forklift transfer, and improves the efficiency of polyethylene sheet transfer.

Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] First, it should be noted that in order to make the purpose and technical solution of this utility model clearer, the technical solution of this utility model will be described more clearly and completely below in conjunction with the accompanying drawings. Obviously, the terms "to the left" and "to the lower right" used in the description are merely a further and clearer description of the technical solution of this utility model based on the accompanying drawings, and cannot represent all the implementation schemes of this utility model.

[0018] like Figures 1 to 3 As shown, a transport mechanism for polyethylene sheets includes a base 1, a movable platform 2 that moves along the base 1 to hold a transfer pallet, and a drive assembly that drives the movable platform 2 to move along the base 1. The base 1 is provided with a slide rail 10, and the lower end face of the movable platform 2 is provided with several sliders 11, which slide in cooperation with the slide rail 10. The base 1 is also provided with a first track 20 and a second track 21, which are located on opposite sides of the slide rail 10. The lower end face of the movable platform 2 is also provided with several first roller assemblies and several second roller assemblies. A roller assembly and several second roller assemblies are located on both sides of the slider 11. The first roller assembly includes a first wheel frame 30 and a first roller 31. The first wheel frame 30 is fixedly connected to the moving platform 2. The first roller 31 is rotatably connected to the first wheel frame 30 through a bearing. The first roller 31 cooperates with the first track 20. The second roller assembly includes a second wheel frame 40 and a second roller 41. The second roller 41 cooperates with the second track 21. The first roller 31 and the second roller 41 are made of metal and are both conical.

[0019] Specifically, in this embodiment, the base 1 is welded from a first square tube A, a second square tube B, a third square tube C, and multiple connecting tubes D. The first square tube A, the second square tube B, the third square tube C, and the connecting tubes D are all made of metal. The slide rail 10 is bolted to the second square tube B. The first track 20 is welded to the first square tube A, the second track 21 is welded to the third square tube C, and the slider 11 is welded to the bottom of the moving platform 2. When the slider 11 slides on the slide rail 10, the moving platform 2 moves simultaneously. The slider 11 can prevent the first roller 31 and the second roller 41 from derailing. The weight borne by the moving platform 2 will be fully distributed to the first roller 31, the second roller 41, and the slider 11.

[0020] In this implementation plan, such as Figure 3As shown, the first roller 31 and the second roller 41 have the same structure, using conical rollers, and both have a wheel cone surface J1. The first track 20 and the second track 21 have the same structure, and both the first track 20 and the second track 21 have a track slope M1. Their wheel cone surfaces J1 contact the track slope M1. Because the wheel diameters of the first roller 31 and the second roller 41 are both longer on the inside and shorter on the outside, and with the restriction of the slider 11, it is difficult for the first roller 31 and the second roller 41 to derail. Secondly, the first roller 31 and the second roller 41 are both made of metal. Because the first roller 31 and the second roller 41 need to bear more weight, and the slider 11 needs to guide the moving platform 2 to move along the base 1, the slider 11 cannot bear too much weight, otherwise it will cause excessive resistance when the moving platform 2 moves on the base 1.

[0021] The drive assembly includes a driver 50, a drive gear 51, and a drive rack 52. The driver 50 is mounted on the mobile platform 2. The drive gear 51 is fixedly connected to the output end of the driver 50. The drive rack 52 is fixed on the base 1, and the drive gear 51 and the drive rack 52 cooperate with each other.

[0022] Specifically, the working principle of this utility model is as follows: After the polyethylene sheet is cut by the cutting machine, the conveyor belt transports the cut polyethylene sheet to the area directly below the sheet adsorption device. The sheet adsorption device adsorbs and stacks the cut polyethylene sheet into the transfer tray on the moving platform 2. Then, the driver 50 is started, and the driver 50 drives the drive gear 51 to rotate. The drive gear 51 moves along the drive rack 52, thereby moving the entire moving platform 2. When the moving platform 2 moves, several sliders 11 below the moving platform 2 move along the slide rail 10. At the same time, several first rollers 31 and several second rollers 41 also move along the first track 20 and the second track 21, respectively. When the moving platform 2 moves to the downstream end of the base 1, the driver 50 stops, and the moving platform 2 stops moving. At this time, the entire transfer tray can be directly transported to the packaging area by a forklift, thereby realizing the transfer of the polyethylene sheet.

[0023] The upper surface of the mobile platform 2 is also provided with an L-shaped baffle 60, which is fixed to the upper surface of the mobile platform 2. The driver 50 is fixed on the L-shaped baffle 60, and a rubber block is provided on the radial end face of the L-shaped baffle 60.

[0024] Specifically, in this embodiment, in order to prevent the polyethylene sheet from colliding with the driver 50 during the transfer process, an L-shaped baffle 60 is provided on the upper end face of the mobile platform 2, and a rubber block (not shown in the figure) is provided on the radial end face of the L-shaped baffle 60. The rubber block reduces the collision between the polyethylene sheet and the L-shaped baffle 60. At the same time, when the polyethylene sheets are stacked, the stacking height is limited by the L-shaped baffle 60 (the stacking height should not exceed the height of the L-shaped baffle 60 to prevent the polyethylene sheet from falling during the transfer process).

[0025] Several buffer blocks 70 are provided at both ends of the base 1.

[0026] Specifically, several buffer blocks 70 are provided at both the upstream and downstream ends of the base 1. The buffer blocks 70 can reduce the impact force caused by the inertia when the mobile platform 2 moves back and forth.
