[0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated cartons, single-layer cardboard boxes, etc., with various specifications and models. Cartons are produced in different sizes according to the usage requirements to package products of different sizes and quantities. When producing cardboard, indentations are generally made on the cardboard of the carton to facilitate subsequent folding, forming and other processes.

[0003] When packaging cardboard boxes are indented, generally an indentation knife is used for indentation. This indentation method is relatively slow, and when indenting, the limitations of the indentation knife are relatively high. One indentation knife can only be applicable to one kind of packaging cardboard, which affects the use of indentation of the packaging cardboard.

[0004] Therefore, it is very necessary to propose a cardboard indentation device for a packaging carton to solve the above problems. Content of the Utility Model

Detailed Embodiment

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] The present invention provides a cardboard indentation device for a packaging carton as shown in Figure 1 - Figure 5 The device includes a conveyor 1. The conveyor 1 is a belt conveyor for conveying cardboard, which is a prior art and will not be described in detail here. Above the conveyor 1, there are multiple groups of indentation modules 4. The indentation module 4 further includes an indentation wheel 5 movably arranged above the conveyor 1. A complementary wheel block 6 is clamped inside the indentation wheel 5. The indentation wheel 5 and the complementary wheel block 6 form a complete circle to indent the cardboard. The cardboard is conveyed by the conveyor 1 for automatic indentation and conveyance.

[0024] Two vertical plates 2 are fixedly arranged at the upper end of the conveyor 1. A central rod 3 is rotatably arranged on the opposite sides of the two vertical plates 2. A conduction plate 7 is fixedly arranged on the outer side of the central rod 3. The indentation wheel 5 movably passes through the central rod 3. A clamping groove 8 is formed through one side of the complementary wheel block 6. The conduction plate 7 is clamped inside the clamping groove 8.

[0025] Through the setting of the indentation wheel 5, when indenting the cardboard, the number of indentation wheels 5 can be controlled according to the number of indentations on the cardboard, and the position of the indentation wheel 5 can be adjusted arbitrarily, improving the applicability of the indentation module 4, enabling the indentation module 4 to adapt to various cardboard and various indentation situations.

[0026] Two fixing blocks 9 are fixedly arranged at one end of the indentation wheel 5. Two fixing shells 10 are fixedly arranged at one end of the complementary wheel block 6. First guiding grooves 12 are formed on the inner walls of both sides of the fixing shell 10. First guiding strips 13 are fixedly arranged at both ends of the horizontal frame 11. The first guiding strips 13 slide inside the corresponding first guiding grooves 12. A horizontal frame 11 is movably arranged inside the fixing shell 10. Second guiding grooves 14 are formed on the inner walls of both sides of the horizontal frame 11. Second guiding strips 16 are fixedly arranged at both ends of the limiting block 15. The second guiding strips 16 slide inside the second guiding grooves 14. A limiting block 15 is movably arranged inside the horizontal frame 11. The first guiding grooves 12 and the limiting block 15 are arranged in a cross shape. The moving directions of the horizontal frame 11 and the limiting block 15 are perpendicular to each other. One end of the limiting block 15 abuts against one end of the fixing block 9.

[0027] One end of the horizontal frame 11 is fixedly provided with a spring 17. The end of the spring 17 far from the horizontal frame 11 is fixedly connected to the inner wall of the fixed shell 10. Through the arrangement of the limit block 15 and the horizontal frame 11, when connecting the indentation wheel 5 and the replenishing wheel block 6, a reaction force is formed on the replenishing wheel block 6 by the spring 17. While the replenishing wheel block 6 presses the conduction plate 7, the indentation wheel 5 is extruded, ensuring its connection stability and enabling the quick disassembly of the indentation wheel 5 with simple and fast operation.

[0028] Working principle: The operator turns on the conveyor 1, and then places the cardboard to be indented on the conveyor 1. The cardboard is conveyed towards the indentation module 4 by the conveyor 1, so that the indentation wheel 5 and the replenishing wheel block 6 contact the cardboard, and then indent the surface of the cardboard. The indentation wheel 5 and the replenishing wheel block 6 are driven by the moving cardboard to rotate, so that the indentation wheel 5 and the replenishing wheel block 6 drive the conduction plate 7 to rotate through the clamping groove 8, and then the conduction plate 7 drives the central rod 3 to rotate, preventing the indentation wheel 5 from sliding on the cardboard and the indentation wheel 5 not rotating, resulting in poor indentation effect.

[0029] When it is necessary to adjust the number or position of the indentation wheels 5, press the limit block 15 to move towards the corresponding fixed block 9, so that the limit block 15 and the fixed block 9 are not in contact. Through the setting of the spring 17, the horizontal frame 11 automatically resets. Its unlocking operation is simple, only need to press the limit block 15 to unlock, and then complete the disassembly of the replenishing wheel block 6. Then, according to the indentation condition of the cardboard, the number and position of the indentation wheels 5 can be controlled to adapt to the indentation conditions of various cardboards.

[0030] When it is necessary to fix the indentation wheel 5 and the replenishing wheel block 6, directly align the replenishing wheel block 6 with the notch of the indentation wheel 5, so that the conduction plate 7 enters the inside of the clamping groove 8, and then press the limit block 15, so that the limit block 15 drives the horizontal frame 11 to move. The horizontal frame 11 is limited by the first guide bar 13 and the first guide groove 12, so that the horizontal frame 11 moves towards the fixed block 9, so that the horizontal frame 11 reaches the side of the fixed block 9 close to the central rod 3. Then press the limit block 15 and the fixed block 9 to contact each other. Through the work of the spring 17, the replenishing wheel block 6 is fixed, so that the clamping groove 8 squeezes the conduction plate 7 to completely fix the positions of the indentation wheel 5 and the replenishing wheel block 6, and then complete the fixation of the indentation wheel 5.
