Description

Technical Field

[0001] This utility model relates to the field of plastic production technology, specifically a transfer device for PE board production. Background Technology

[0002] Plastics are polymer materials made primarily of natural or synthetic resins, with various additives added, processed under specific temperature and pressure conditions, and capable of maintaining their shape at room temperature. Among them, polyethylene (PE) sheets, as a typical representative of thermoplastic plastics, are widely used in industrial fields such as packaging containers, building templates, and electronic device insulation due to their excellent chemical stability, mechanical properties, and processing characteristics.

[0003] In the PE board production process, there are significant technical challenges in the transfer process. Patent CN218172295U discloses a transfer mechanism for plastic board production. This patent uses four sets of telescopic rods to limit the movement of two sets of extension plates while providing auxiliary support, ensuring the extension tubes can only move in a straight, lateral direction. This increases the distance between the extension plates and the base plate, thereby increasing the placement area of ​​the device. However, in practical applications, due to the lack of a matching mechanism with the production line's conveyor rollers, secondary transfer using specialized equipment such as forklifts is required, leading to reduced operational efficiency. Furthermore, because of the smooth surface of PE boards, they are prone to slipping and shifting during transport, requiring frequent manual adjustments. Transporting on ramps also poses safety hazards. Therefore, a transfer device for PE board production is urgently needed to solve these problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a transfer device for PE board production, which has advantages such as stable conveying and solves the problems of existing technologies requiring secondary transfer with specialized equipment such as forklifts, resulting in reduced work efficiency, and the boards being prone to slippage and displacement during transportation.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A transfer device for PE board production includes a trolley bracket, an auxiliary conveying mechanism is provided inside the trolley bracket, and a protective mechanism is provided at the bottom of the trolley bracket. The auxiliary conveying mechanism includes a conveying roller rotatably connected inside the trolley bracket. The rotating shaft of the conveying roller passes through the back of the trolley bracket and is fixedly connected to a brake wheel. A fixed shell is fixedly connected to the back of the trolley bracket. A fixed rod is slidably connected inside the fixed shell. A friction brake strip is fixedly connected to one end of the fixed rod that passes through to the bottom of the fixed shell. A fixed ring is fixedly sleeved on the outside of the fixed rod. A spring is connected between the bottom of the fixed ring and the bottom wall of the fixed shell. The protective mechanism includes an adjusting bracket fixedly connected to the bottom of the trolley bracket. Two-way threaded rods are rotatably connected to the inner walls of both sides of the adjusting bracket through bearings. An adjusting seat is threadedly connected to the outside of the two-way threaded rod. A protective railing is vertically fixedly connected to the top of the adjusting seat.

[0008] The beneficial effects of this utility model are:

[0009] This PE board production transfer device features conveyor rollers that connect with the production line's conveyor rollers for feeding. It utilizes friction brake bars to brake the brake wheels, improving stability during transport. The bidirectional threaded rod-driven guardrail movement is adaptable to various sizes of PE boards.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, an installation plate is fixedly connected to the side wall of the fixed shell, a limit block is rotatably connected to the top of the installation plate, a limit groove is formed inside the limit block, and a locking block that matches the limit groove is fixedly connected to the top of the fixed rod.

[0012] The beneficial effect of adopting the above-mentioned further solution is that by pressing down the fixing rod and rotating the limiting block, the locking block is engaged in the limiting groove, forming a mechanical interlock.

[0013] Furthermore, the inner wall of the adjusting bracket is fixedly connected with two sliding rods in parallel, and the adjusting seat is provided with a linear bearing that cooperates with the sliding rods. The adjusting seat is slidably connected to the sliding rods through the linear bearing.

[0014] The advantage of adopting the above-mentioned further solution is that the double slide bar structure ensures that the adjusting seat moves stably along the axial direction.

[0015] Furthermore, a handwheel is fixedly connected to one end of the bidirectional threaded rod extending to the back of the adjusting bracket. There are two adjusting seats, each with a left-handed and a right-handed threaded hole, symmetrically distributed on both sides of the threaded section of the bidirectional threaded rod.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the symmetrical thread design enables the two guardrails to move synchronously in opposite directions, and can be adapted to various sizes of PE boards for protection.

[0017] Furthermore, the bottom four corners of the trolley bracket are fixedly connected to support bases, and the bottom of the support bases is equipped with universal wheels with brakes via a steering mechanism. The bottom end of the brake wheel contacts the top surface of the friction brake strip, and the contact surface of the friction brake strip is covered with a high friction coefficient material.

[0018] The beneficial effect of adopting the above-mentioned further solution is that by contacting the friction brake strip with the brake wheel, the conveyor roller cannot rotate, thereby improving the stability during conveying.

[0019] Furthermore, the trolley bracket is internally rotatably connected with an alignment plate. There are two alignment plates, which are symmetrically distributed at both ends of the trolley bracket. The rotating parts of the two alignment plates are provided with polyurethane friction pads.

[0026] 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.

[0027] In the embodiments, by Figure 1-4 The present invention discloses a transfer device for PE board production. The present invention includes a trolley bracket 1, an auxiliary conveying mechanism is provided inside the trolley bracket 1, the auxiliary conveying mechanism includes a conveying roller 2 rotatably connected inside the trolley bracket 1, the rotating shaft of the conveying roller 2 passes through the back of the trolley bracket 1 and is fixedly connected to a brake wheel 3, a fixed shell 4 is fixedly connected to the back of the trolley bracket 1, a fixed rod 5 is slidably connected inside the fixed shell 4, a friction brake strip 6 is fixedly connected to one end of the fixed rod 5 that passes through to the bottom of the fixed shell 4, a fixed ring 7 is fixedly sleeved on the outside of the fixed rod 5, and a spring 8 is connected between the bottom of the fixed ring 7 and the inner bottom wall of the fixed shell 4.

[0028] In this embodiment, in actual use, there are several conveying rollers 2. The bottom end of the brake wheel 3 contacts the top surface of the friction brake strip 6. The contact surface of the friction brake strip 6 is covered with a high friction coefficient material, such as polyurethane or rubber. By contacting the brake wheel 3 with the friction brake strip 6, the conveying roller 2 cannot rotate, thus improving the stability during conveying.

[0029] Specifically, refer to Figure 4 A mounting plate 13 is fixedly connected to the side wall of the fixed shell 4. A limiting block 14 is rotatably connected to the top of the mounting plate 13. A limiting groove 15 is opened inside the limiting block 14. A locking block 16 that matches the limiting groove 15 is fixedly connected to the top of the fixed rod 5.

[0030] In this embodiment, during actual use, the fixing rod 5 is pressed down and the limiting block 14 is rotated so that the locking block 16 is engaged in the limiting groove 15, forming a mechanical interlock. At this time, the friction brake strip 6 moves down with the fixing rod 5, canceling the braking state of the brake wheel 3, which facilitates the conveyor roller 2 to roll and transfer the goods.

[0031] Specifically, refer to Figure 2The bottom of the trolley support 1 is provided with a protective mechanism, which includes an adjusting bracket 9 fixedly connected to the bottom of the trolley support 1. The inner walls of both sides of the adjusting bracket 9 are rotatably connected to a double-threaded rod 10 through bearings. The outer thread of the double-threaded rod 10 is connected to an adjusting seat 11. The top of the adjusting seat 11 is vertically fixedly connected to a protective railing 12. The inner wall of the adjusting bracket 9 is fixedly connected with two sliding rods 17 in parallel. The adjusting seat 11 is provided with a linear bearing that cooperates with the sliding rod 17. The adjusting seat 11 is slidably connected to the sliding rod 17 through the linear bearing.

[0032] A handwheel 18 is fixedly connected to one end of the bidirectional threaded rod 10 extending to the back of the adjusting bracket 9. There are two adjusting seats 11, each with a left-hand and a right-hand threaded hole, symmetrically distributed on both sides of the threaded section of the bidirectional threaded rod 10.

[0033] In this embodiment, in actual use, the double slide bar structure ensures that the adjusting seat 11 moves stably along the axial direction. The handwheel 18 drives the bidirectional threaded rod 10 to rotate, thereby moving the adjusting seat 11. The symmetrical thread design enables the double guardrails to move synchronously in opposite directions, and can be adapted to various sizes of PE boards for protection.

[0034] The bottom of the trolley bracket 1 is fixedly connected to the four corners of the support base 19. The bottom of the support base 19 is equipped with a universal wheel 20 with brake via a steering mechanism. The trolley bracket 1 is rotatably connected to the internal alignment plate 21. There are two alignment plates 21, which are symmetrically distributed at both ends of the trolley bracket 1. The rotating parts of the two alignment plates 21 are provided with polyurethane friction pads. The back of the adjustment bracket 9 is fixedly connected to the anti-slip handle 22 at an angle.

[0035] When the alignment plate 21 is set horizontally, by aligning the alignment plate 21 with the production line conveyor roller, the stacked PE boards can slide from the production line conveyor roller to the conveyor roller 2 on the trolley bracket 1. By rotating the alignment plate 21 upward, it can be folded and stored and provide a certain degree of obstruction and protection.

[0036] Working principle:

[0037] By moving the trolley bracket 1 to one side of the production line conveyor roller, the alignment plate 21 is horizontally unfolded so that its end is close to the production line conveyor roller. The fixing rod 5 is pressed down and the limiting block 14 is rotated so that the locking block 16 is engaged in the limiting groove 15, forming a mechanical interlock. At this time, the friction brake strip 6 moves down with the fixing rod 5, canceling the braking state of the brake wheel 3. The alignment plate 21 along the stacked PE board is pushed into the transfer device by hand. The conveyor roller 2 rotates under the gravity of the board. Then, the limiting block 14 is manually rotated so that the fixing rod 5 is reset under the elastic action of the spring 8, so that the friction brake strip 6 presses the brake wheel 3 to prevent the conveyor roller 2 from rotating randomly during transportation. The handwheel 18 is turned to drive the bidirectional threaded rod 10, and the guardrails 12 on both sides move closer together at the same speed until the guardrails 12 touch the two sides of the PE board.
