It is a type of gluing machine with a pre-folding mechanism mainly used for folding the edges of cardboard and is quite common in the existing technology.

[0003] Existing technologies, such as the utility model patent with publication number CN220904249U, disclose a pre-folding mechanism for a box-gluing machine. This patent employs a worktable with a conveyor belt. A bidirectional screw is rotatably mounted on the worktable, perpendicular to the transmission direction of the conveyor belt, and both ends of the bidirectional screw are screwed to first mounting seats. A slide rod is fixedly connected to the worktable, and two second mounting seats are slidably sleeved on the slide rod. An adjusting baffle is fixedly connected between adjacent first and second mounting seats on the same side. This utility model, by rotating the bidirectional screw, drives the two first mounting seats to move away or closer, thereby adjusting the distance between the two adjusting baffles. This extends the range of products that can be produced beyond the originally set production size range, avoiding the need to purchase new equipment and reducing costs.

[0004] The inventors discovered in their daily work that replacing the folding plate was cumbersome because the existing folding plate was fixed to the moving block with multiple bolts, and the replacement process required the use of tools such as screwdrivers. This method of operation was very complicated and led to low work efficiency. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] Please see Figure 1 and Figure 2 The present invention provides a pre-folding mechanism for a box gluing machine, comprising: a box gluing machine body 1, a folding device 2 installed inside the box gluing machine body 1, four moving blocks 4 installed inside the folding device 2, the four moving blocks 4 being in pairs, a connecting plate 5 being fixedly connected to the side of each pair of moving blocks 4 that is close to each other, a folding plate 6 being installed on the upper surface of each pair of moving blocks 4 by means of a replacement structure 3, and a replacement structure 3 being provided on the inner wall of the moving blocks 4.

[0029] In the embodiments of this utility model, please refer to Figures 3 to 5The replacement structure 3 includes a limiting groove 301 and a connecting groove 308. The limiting groove 301 is formed on the moving block 4, and the connecting groove 308 is formed on the moving block 4. The inner wall of the limiting groove 301 is slidably connected to the connecting block 306 and the top plate 304. The two connecting blocks 306 are fixedly connected to the folding plate 6. The inner wall of the connecting block 306 is provided with a slot 307. A compression spring 303 is provided between the side of the top plate 304 away from the connecting block 306 and the limiting groove 301. Both ends of 03 are fixedly connected to the top plate 304 and the limiting groove 301, respectively. A locking block 309 is slidably connected to the inner wall of the connecting groove 308. The locking block 309 is slidably connected to the locking groove 307. A connecting rod 313 is fixedly connected to the side of the locking block 309 away from the locking groove 307. The connecting rod 313 is slidably connected to the moving block 4. A spring 310 is sleeved on the arc surface of the connecting rod 313. Both ends of the spring 310 are fixedly connected to the locking block 309 and the connecting groove 308, respectively. This achieves the effect of allowing personnel to quickly and easily replace the folding plate 6 when it needs to be replaced after long-term wear. A protective pad 305 is fixedly connected to the upper surface of the top plate 304, and the protective pad 305 is slidably connected to the limiting groove 301. The protective pad 305 protects the connecting block 306 and the top plate 304, preventing direct contact between them. A telescopic rod 302 is fixedly connected to the bottom wall of the limiting groove 301, with its output end fixedly connected to the top plate 304. The telescopic rod 302 limits the top plate 304, preventing misalignment during sliding within the limiting groove 301. A handle 311, shaped like a "U," is fixedly connected to the end of the connecting rod 313 furthest from the locking block 309, facilitating easy movement and improving operational convenience. An anti-slip sleeve 312, with a hollow circular cross-section, is fixedly connected to the arc surface of the handle 311. The anti-slip sleeve 312 increases the friction between the user's hand and the handle 311, preventing slippage during movement. The connecting block 306 is made of stainless steel. Stainless steel has high strength and good wear resistance, preventing deformation of the connecting block 306 during short-term use.

[0030] The working principle of the pre-folding mechanism of the box gluing machine provided by this utility model is as follows: When the operator needs to replace the folding plate 6, the operator can first move the two anti-slip sleeves 312. The anti-slip sleeves 312 drive the handle 311 to move. The anti-slip sleeves 312 can increase the friction between the operator's hand and the handle 311, which can prevent the operator from slipping during the movement of the handle 311. Then the handle 311 drives the connecting rod 313 to move away from the slot 307. The handle 311 facilitates the operator's movement of the connecting rod 313, which can improve the operator's ease of operation. Then the connecting rod 313 drives the locking block 309 to move away from the slot 307. The locking block 309 drives the spring 310 to rewind until the locking block 309 slides out of the inner wall of the slot 307. When the locking block 309 slides out of the inner wall of the slot 307, the compression spring 303 rebounds and drives the top plate 304 upward. The top plate 304 moves upward, driving the output ends of the protective pad 305 and the telescopic rod 302. The protective pad 305 protects the connecting block 306 and the top plate 304, preventing direct contact between them. The telescopic rod 302 limits the top plate 304, preventing misalignment during sliding within the limiting groove 301. The protective pad 305 then moves the connecting block 306 upward, which in turn moves the folding plate 6 upward until part of the connecting block 306 slides out of the limiting groove 301. The folding plate 6 is then moved, causing it to move the two connecting blocks 306 upward until they slide out of the limiting groove 301. The connecting block 306, made of stainless steel, has high strength and good wear resistance, preventing deformation during short-term use.

[0031] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
