Description

Technical Field

[0001] This utility model relates to the field of cement block stacking technology, and in particular to a pallet positioning device for a cement block stacking machine. Background Technology

[0002] Cement blocks, as an important material in the construction industry, require palletizers to neatly stack the shaped blocks onto pallets during automated production for subsequent transportation and storage. In this process, the stability and adaptability of the pallet positioning device directly affect the palletizing accuracy and production efficiency. Traditional palletizers generally use fixed-interval positioning mechanisms, physically constraining the pallets through rigid baffles or limit blocks.

[0003] Currently, most mainstream positioning devices on the market adopt a welded or bolted structure. The spacing between the baffles is determined during equipment installation. This rigid design requires manual replacement of positioning components or overall adjustment of the mechanical structure to adapt to different pallet sizes (such as common sizes like 1200×800mm and 1000×600mm).

[0004] In practice, frequent mechanical disassembly and assembly not only increases production line downtime (statistics show that a single adjustment takes about 30-60 minutes), but also significantly increases equipment maintenance costs and the labor intensity of operators, making it difficult to meet the requirements of modern production lines for rapid changeover. To address these issues, we propose a pallet positioning device for a cement block stacking machine. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a pallet positioning device for a cement block stacking machine.

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

[0007] A pallet positioning device for a cement block stacking machine includes a conveyor table, support legs, and a support plate. The support plate is fixedly connected to the top of the support legs, and a panel is fixedly installed on the front of the support plate. A rectangular cover is fixedly installed at the center of the front of the panel, and a rocker arm is installed at the bottom of the rectangular cover via a bearing. A second bevel gear is fixedly connected to the top of the rocker arm, and a first bevel gear meshes with the left side of the top of the second bevel gear. A movable rod is inserted through the center of the first bevel gear, and first sliders are symmetrically fitted on the left and right surfaces of the movable rod. A first limiting block is inserted inside the first slider, and a limiting plate is fixedly connected to the front of the first limiting block.

[0008] Preferably, the surface of the first slider is fitted with a guide groove, and there are two sets of guide grooves. The two sets of guide grooves are symmetrically arranged and installed on the surface of the support plate. The upper and lower ends of the first slider abut against the inner walls of the upper and lower ends of the guide groove.

[0009] Preferably, the limiting plate is provided in two sets, and the back of the two sets of limiting plates is symmetrically fixedly connected with a second slider, and the surface of the second slider is fitted with a pull rod.

[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 pallet positioning device for a cement block stacking machine includes a conveyor table 1, a support leg 2, and a support plate 3. The support plate 3 is fixedly connected to the top of the support leg 2, and a panel 4 is fixedly installed on the front of the support plate 3. A rectangular cover 5 is fixedly installed at the center of the front of the panel 4, and a rocker arm 15 is installed at the bottom of the rectangular cover 5 through a bearing. A second bevel gear 14 is fixedly connected to the top of the rocker arm 15, and a first bevel gear 13 meshes with the left side of the top of the second bevel gear 14. A movable rod 16 is inserted through the center of the first bevel gear 13, and a first slider 7 is symmetrically sleeved on the left and right surfaces of the movable rod 16. A first limiting block 10 is inserted inside the first slider 7, and a limiting plate 8 is fixedly connected to the front of the first limiting block 10.

[0024] Furthermore, refer to Figure 1 and Figure 2 It can be seen that the surface of the first slider 7 is fitted with a guide groove 6, and there are two sets of guide grooves 6. The two sets of guide grooves 6 are symmetrically arranged and installed on the surface of the support plate 3. The upper and lower ends of the first slider 7 abut against the inner walls of the upper and lower ends of the guide groove 6. During use, the first slider 7 is limited by the guide groove 6 and moves linearly along the inside of the guide groove 6.

[0025] Furthermore, refer to Figure 3 It can be seen that there are two sets of limiting plates 8. The back of the two sets of limiting plates 8 are symmetrically fixedly connected with second sliders 12, and the surface of the second sliders 12 is fitted with pull rods 9. During use, by pulling the pull rods 9, it is convenient to adjust the movement of the two sets of limiting plates 8 at the same time.

[0026] Furthermore, refer to Figure 3 It can be seen that the surface of the pull rod 9 is provided with a slide rail, and the second slider 12 passes through the slide rail and is fixedly connected to the second limit block 11. During use, the second limit block 11 can limit the pull rod 9 and play a role in preventing it from falling off. The second slider 12 can move laterally along the inside of the slide rail to adjust the spacing of the limit plate 8.

[0027] Furthermore, refer to Figure 4 It can be seen that the first slider 7 has a T-shaped groove inside, and the first limiting block 10 is a T-shaped protrusion. The first limiting block 10 is inserted into the T-shaped groove. The side wall of the first limiting block 10 is provided with an anti-slip layer, and the inner wall of the T-shaped groove is provided with an anti-slip layer. During use, when the limiting plate 8 is pulled forcefully, the first limiting block 10 can move inside the T-shaped groove to adjust the distance between the bottom end of the limiting plate 8 and the conveyor table 1, so as to adapt to trays of different thicknesses. The first limiting block 10 and the inner wall of the T-shaped groove can generate friction through the anti-slip layer to limit the first limiting block 10 and ensure the stability of the limiting plate 8 during use.

[0028] Furthermore, refer to Figure 5 It can be seen that the two ends of the movable rod 16 are provided with external threads on the surface of the end inside the guide groove 6, and the external threads are arranged in opposite directions. The first slider 7 has a threaded hole through it, and the threaded hole is adapted to the external thread on the surface of the movable rod 16, so as to facilitate the adjustment of the first slider 7 to drive the limiting plate 8 to move. The distance between the limiting plates 8 can be adjusted according to the size of the pallet to achieve the effect of adapting to the limiting of multiple pallets.

[0029] Working principle: When using this utility model, according to the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 5 As shown, when it is necessary to adjust the spacing between the limiting plates 8, the operator manually rotates the rocker arm 15. The rotation of the rocker arm 15 drives the second bevel gear 14 to rotate, the rotation of the second bevel gear 14 drives the first bevel gear 13 to rotate, the rotation of the first bevel gear 13 drives the movable rod 16 to rotate, and the rotation of the movable rod 16 drives the first slider 7 to move along the inside of the guide groove 6. The movement of the first slider 7 drives the limiting plate 8 to move, which is convenient for adjustment according to the size of the pallet.

[0030] When it is necessary to adjust the distance between the bottom of the limiting plate 8 and the conveyor 1, the operator manually moves the limiting plate 8 up and down. The limiting plate 8 drives the first limiting block 10 to move in the groove opened in the first slider 7, thereby realizing the adjustment. The operation is completed. The above is the entire working principle of this utility model.

As long as they can achieve their beneficial effects, they can be implemented, so they will not be described in detail.
