Description

Technical Field

[0001] This utility model relates to the field of cardboard box forming technology, specifically a bending and assembly device for corrugated cardboard box forming. Background Technology

[0002] Corrugated cardboard boxes are rigid paper boxes made from corrugated cardboard through processes such as die-cutting, creasing, stapling, or gluing. They are one of the most widely used packaging containers in modern commerce and trade. They are mainly composed of a face liner, a core liner, and a linerboard. The face liner is the outermost layer of the box, usually made of kraft paper or white paper, offering high strength and aesthetics. The core liner is the wavy paper layer between the face liner and the linerboard, also known as corrugated paper, and is the main load-bearing part of the corrugated cardboard box. Depending on the flute type, they are classified into types A, B, C, E, and F.

[0003] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found:

[0004] In the current technology, the assembly of corrugated boxes is usually completed by manual assistance or automated equipment. Manual assistance is not only labor-intensive and inefficient, but also prone to inaccurate bending angles and low assembly precision due to differences in operator operation, which affects the overall quality of the boxes. While automated equipment can avoid the drawbacks of manual operation, it usually requires a complete production line to operate, which is not only expensive in the initial stage, but also relatively expensive in subsequent maintenance and debugging costs. Utility Model Content

[0005] To address the issues of high labor intensity in manual assistance methods and high initial costs of automated equipment, the purpose of this utility model is to provide a bending and assembly device for corrugated cardboard box forming.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: a bending assembly device for corrugated cardboard box forming, including a processing table, a bending mechanism above the processing table for bending and forming cardboard, a disassembly and assembly mechanism inside the bending mechanism for replacing the bending plate to adapt to cardboard of different sizes, and a positioning mechanism inside the bending mechanism for improving the stability of the bending mechanism.

[0007] The bending mechanism includes multiple sets of symmetrically distributed support plates. A base plate is fixedly installed at the top of each set of support plates. A slot is opened at the top of the base plate, and a movable plate is movably engaged inside the slot. A symmetrically distributed L-shaped plate is fixedly installed at the top of the base plate. An inclined slot is opened at the top of the L-shaped plate, and a sleeve is movably engaged inside the inclined slot. A movable rod passes through the sleeve. A fixing block is fixedly installed on one side of the top of the movable plate, and the movable rod passes through the fixing block. A symmetrically distributed movable plate is movably fitted on the outside of the movable rod. Two movable plates are fixedly connected to their corresponding sleeves. A flip plate is fixedly installed at the top of the movable plate, and a bending plate is detachably installed above the flip plate.

[0008] Preferably, a second electric push rod is provided above the processing table, and a pressure plate is fixedly connected to the output end of the second electric push rod. A placement platform is fixedly installed on the top of the processing table.

[0009] Preferably, the disassembly and assembly mechanism includes two mounting plates, both of which are fixedly connected to the flip plate. The mounting plates have slots inside, and the bottom of the bent plate is fixedly fitted with symmetrically distributed clamping plates, which are clamped in the slots. The clamping plates and the mounting plates have symmetrically distributed first fixing holes on both sides.

[0010] Preferably, the positioning mechanism includes a horizontal plate fixedly connected to the L-shaped plate, and symmetrically distributed positioning blocks are fixedly installed on the top of the horizontal plate.

[0011] Preferably, a bracket is fixedly installed on the top of the first electric push rod, and symmetrically distributed stabilizing plates are fixedly installed on the top of the bracket. The top of the stabilizing plates is provided with symmetrically distributed second fixing holes.

[0012] Preferably, vertical plates are fixedly installed at the four corners of the top of the processing table, and a connecting plate is fixedly installed at one end of the multiple vertical plates, with the second electric push rod fixedly passing through the connecting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This application achieves automated bending and forming of corrugated boxes through a bending mechanism.

[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. 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.

[0023] like Figure 1-4 As shown, this utility model discloses a bending and assembly device for corrugated cardboard box forming, and provides the following two embodiments:

[0024] Example 1: A bending assembly device for corrugated cardboard box forming includes a processing table 101. A bending mechanism 1 is provided above the processing table 101 to realize the bending and forming of cardboard. At the same time, a disassembly and assembly mechanism 2 is provided inside the bending mechanism 1 to replace the bending plate 192 to adapt to cardboard of different sizes. A positioning mechanism 3 is also provided inside the bending mechanism 1 to improve the stability of the bending mechanism 1.

[0025] The bending mechanism 1 includes multiple sets of symmetrically distributed support plates 11. A base plate 12 is fixedly installed at the top of each set of support plates 11. A slot 13 is formed at the top of the base plate 12. A movable plate 14 is movably engaged inside the slot 13. A symmetrically distributed L-shaped plate 15 is fixedly installed at the top of the base plate 12. A sloping groove 16 is formed at the top of the L-shaped plate 15. A sleeve 161 is movably engaged inside the sloping groove 16. A movable rod 17 passes through the sleeve 161. A fixing block 18 is fixedly installed on one side of the top of the movable plate 14. The movable rod 17 is fixedly inserted through the fixed block 18. The outer side of the movable rod 17 is movably fitted with symmetrically distributed movable plates 19. The two movable plates 19 are respectively fixedly connected to the corresponding sleeves 161. The top of the movable plate 19 is fixedly installed with a flip plate 191. A bending plate 192 is detachably installed above the flip plate 191. A second electric push rod 194 is provided above the processing table 101. The output end of the second electric push rod 194 is fixedly connected with a pressure plate 195. A placement table 196 is fixedly installed at the top of the processing table 101.

[0026] Example 2 differs from Example 1 in that the disassembly and assembly mechanism 2 includes two mounting plates 21, both of which are fixedly connected to the flip plate 191. The mounting plates 21 have slots 22 inside, and the bottom of the bending plate 192 is fixedly fitted with symmetrically distributed clamping plates 23, which are clamped in the slots 22. Both the clamping plates 23 and the mounting plates 21 have symmetrically distributed first fixing holes 24 on both sides. Through the mounting plates 21 and clamping plates 23, the operator can pass the fixing screws through the first fixing holes 24 and tighten them to fix the bending plate 192. At the same time, disassembly is also relatively simple, making it convenient for the operator to replace the bending plate 192 according to the size of the carton.

[0027] The positioning mechanism 3 includes a horizontal plate 31 fixedly connected to the L-shaped plate 15. The top of the horizontal plate 31 is fixedly equipped with symmetrically distributed positioning blocks 32. Through the horizontal plate 31 and the positioning blocks 32, the flip plate 191 can be positioned to avoid the flip plate 191 from shifting and improve stability.

[0028] A bracket 41 is fixedly installed on the top of the first electric push rod 193. A symmetrically distributed stabilizing plate 42 is fixedly installed on the top of the bracket 41. A symmetrically distributed second fixing hole 43 is opened at the top of the stabilizing plate 42. By setting the bracket 41 and the stabilizing plate 42, the first electric push rod 193 can be fixed.

[0029] Vertical plates 51 are fixedly installed at the four corners of the top of the processing table 101. A connecting plate 52 is fixedly installed at one end of the multiple vertical plates 51. The second electric push rod 194 is fixedly inserted through the connecting plate 52. By setting the vertical plates 51 and the connecting plate 52, the second electric push rod 194 can be supported.

[0030] Working principle: In actual use, the cardboard coated with glue is placed on top of the placement platform 196. By activating the second electric push rod 194, its output end drives the pressure plate 195 to descend until it is pressed against the cardboard and applies a certain pressure. Then, by activating the first electric push rod 193, its output end pushes the moving plate 14 to move. The moving plate 14 drives the fixed block 18 and the movable rod 17 to move. The movable rod 17 drives the flipping plate 191 and the bending plate 192 to move through the movable plate 19. While the movable rod 17 moves through the inclined groove 16, it also drives the sleeve 161 to move. Simultaneously, the movable rod 17 applies a certain pressure to the sleeve 161, causing the sleeve 161 to rotate while moving, which in turn drives the movable plate 19 to rotate. The movable plate 19 then drives the flipping plate 191 and the bending plate 192 to rotate, allowing the bending plate 192 to bend the side of the cardboard and form the carton. Through the mounting plate 21 and the clamping plate 23, the operator passes the fixing screw through the first fixing hole 24 and tightens it to fix the bending plate 192. Disassembly is also relatively simple, making it convenient for the operator to replace the bending plate 192 according to the size of the carton.

[0031] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
