Description

Technical Field

[0001] This utility model relates to the field of auxiliary technology for sheet metal processing, specifically a sheet metal stacking and lifting platform. Background Technology

[0002] A board stacking lifting platform is a mechanical device specifically designed for stacking boards. It has the basic function of lifting and supporting the boards. By placing the platform at the board discharge port, the boards are directly stacked on the lifting platform after being discharged. By changing its position, multiple layers of boards can be stacked. It is widely used in the furniture manufacturing industry, building decoration material production and other fields.

[0003] A search revealed Chinese patent application CN202221193545.5, which discloses a lifting platform for stacking steel grating sheets. The platform includes a base and a lifting platform located above the base. A lifting mechanism is provided between the base and the lifting platform to drive the lifting platform up and down. The lifting mechanism includes a drive component fixedly mounted on the base, two diagonal braces distributed on opposite sides of the lifting platform, and a connecting plate connecting the two diagonal braces. One end of each diagonal brace is hinged to the lifting platform, and the other end is movably mounted on the base. The drive component is connected to the connecting plate and drives the moving end of the diagonal brace to move on the base to achieve the lifting action of the lifting platform. This lifting platform can automatically stack steel grating sheets without manual handling, saving time and labor, improving production efficiency, and reducing labor costs.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: Although the above solutions achieve stacking adjustment of the boards through lifting actions, during the stacking process, when the boards move from the discharge port to the lifting platform, although there is no significant change, each time they move to the top, due to factors such as the discharge speed, angle, and the inertia of the boards themselves, there may be slight differences in their placement. When the boards at the bottom of the stack are subjected to pressure from the boards above, these slight differences are not easy to adjust and can easily affect the stability of subsequent transportation. Therefore, it is necessary to design a board stacking lifting platform with strong practicality and positioning function. Utility Model Content

[0021] 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.

[0022] Please see Figure 1-4 The present invention provides a technical solution: a plate stacking lifting platform, including a base 1, a scissor arm 2 is provided on the upper side of the base 1, a driving hydraulic cylinder 3 that cooperates with the scissor arm 2 is provided on the upper side of the base 1, a bearing platform 4 is provided on the upper side of the scissor arm 2, a driving cavity 5 is provided inside the bearing platform 4, a plurality of tightening ports 6 are provided on the inner wall of the driving cavity 5, tightening blocks 7 are slidably fitted on the inner wall of the plurality of tightening ports 6, and a driving mechanism 8 that cooperates with the plurality of tightening blocks 7 is provided on the lower side of the inner wall of the driving cavity 5.

[0023] The upper side of the bearing platform 4 is provided with multiple positioning grooves 9, and the inner walls of the multiple positioning grooves 9 are slidably fitted with positioning blocks 10. The upper side of the multiple positioning blocks 10 is fixedly connected with an alignment plate 11. The multiple tightening blocks 7 are provided with linkage ports 12 that slidably fit with the alignment plate 11. A reset spring 13 is provided between the positioning grooves 9 and the positioning blocks 10.

[0024] Please see Figure 4 The drive mechanism 8 includes a drive motor 801 fixedly connected to the lower side of the inner wall of the drive cavity 5, a pull ring 802 fixedly connected to the output end of the drive motor 801, and a soft steel cable 803 fixedly connected between the pull ring 802 and multiple tightening blocks 7. The drive motor 801 is fixed to the lower side of the inner wall of the drive cavity 5. After it is started, it drives the pull ring 802 at the output end to rotate. The pull ring 802 pulls multiple tightening blocks 7 through the soft steel cable 803 fixedly connected to it, thereby controlling the movement of the tightening blocks 7 to achieve the corresponding function.

[0025] Please see Figure 1 An anti-slip pad 14 is fixedly connected to the upper side of the support platform 4. The upper side of the anti-slip pad 14 may be provided with anti-slip texture. The anti-slip texture provided on the anti-slip pad 14 can increase the friction between it and the pallet placed on the support platform 4, so that the board is more stable when placed on the support platform 4 and avoids slippage.

[0026] Please see Figure 1 Both sides of the base 1 are fixedly connected to positioning seats 15. The upper side of each positioning seat 15 is provided with linkage holes 16, which can be connected and cooperated with external related devices through linkage holes 16, thereby realizing the positioning and installation of the entire plate stacking and lifting platform, ensuring that it can be stably in the corresponding working position during use, ensuring normal operation of the equipment and coordination with surrounding equipment.

[0027] Please see Figure 4 The pull ring 802 has multiple storage slots 17, which cooperate with the soft steel cable 803. The multiple storage slots 17 can be of different heights. When the pull ring 802 rotates, the soft steel cable 803 will be regularly wound up in the storage slots 17, reducing the possibility of multiple soft steel cables 803 getting tangled.

[0028] Please see Figure 2 Multiple guide blocks 18 are fixedly connected to the upper side of the drive cavity 5. One side of the multiple guide blocks 18 is provided with a guide port 19 that cooperates with the soft steel cable 803. When the drive mechanism 8 operates and the soft steel cable 803 moves accordingly, the guide port 19 can provide a precise guide path for the soft steel cable 803, constrain the movement direction of the soft steel cable 803, and further prevent it from swinging or getting tangled.

[0029] Please see Figure 2Multiple guide slots 20 are provided on the upper side of the base 1. The inner walls of the multiple guide slots 20 are slidably fitted with lifting guide plates 21 that are fixedly connected to the bearing platform 4. When the bearing platform 4 moves up and down through the scissor arm 2 and the driving hydraulic cylinder 3, the guide slots 20 guide and limit the lifting guide plates 21 to ensure that the bearing platform 4 moves up and down smoothly along a fixed trajectory, avoiding deviation, shaking and other situations, and ensuring the stability of the lifting process.

[0030] The implementation principle of this application is as follows: When in use, firstly, the lifting platform is installed at the discharge port of the corresponding plate equipment, a tray is placed on the upper side of the bearing platform 4, and the anti-slip pad 14 increases the friction. Then, by driving the extension and retraction of the hydraulic cylinder 3, the bearing platform 4 can be driven to perform corresponding lifting operations. After placing a plate once, the plate thickness is lowered so that the surface of the plate is always flush with the discharge port, thus achieving the stacking of the plates.

[0031] After stacking, the support platform 4 is moved downwards, which activates the drive mechanism 8 in the drive cavity 5. The drive motor 801 drives the pull ring 802 to rotate, and the soft steel cable 803 pulls multiple tightening blocks 7, causing the tightening blocks 7 to slide inwards along the tightening opening 6. The linkage opening 12 on the tightening block 7 slides and engages with the alignment plate 11, thereby pushing the positioning block 10 to move along the positioning groove 9. The multiple alignment plates 11 cooperate with each other to achieve precise positioning and tightening of the boards, realize automatic correction of small deviations in the placement of the boards, ensure that the stacking position of each board is consistent, and improve the quality of stacking.

[0032] After positioning is completed, the drive motor 801 is started to reverse. The positioning block 10 drives the alignment plate 11 to reset under the action of the reset spring 13, so that the multiple alignment plates 11 expand to avoid affecting the next feeding and wait for the next material placement. The height of the alignment plate 11 can be lower than the height of the corresponding equipment outlet. When the bearing platform 4 moves downward, the material above it enters between the multiple alignment plates 11 and is positioned by the tightening of the multiple alignment plates 11.
