Description

Technical Field

[0001] This utility model belongs to the technical field of subcontracting devices, and in particular relates to a subcontracting device. Background Technology

[0002] Cardboard boxes are a common packaging material, widely used for the transportation and storage of goods. Conveyor belts are conveying devices that continuously transport boxes along a designed route, capable of horizontal, inclined, vertical, or circular transport. The conveyor route is fixed, with high conveying capacity and long transport distance, and is widely used in various industries. Products packaged in cardboard boxes are generally also transported via conveyor belts. However, to save space and improve packaging efficiency, cardboard boxes are often pressed together, making them inconvenient to handle.

[0003] Currently, most conveyor lines are equipped with packaging devices to separate cartons, allowing adjacent cartons to be separated for easier handling. However, existing devices require complex electrical control systems to achieve packaging, and the installation and debugging process is cumbersome and has a high failure rate.

[0004] Therefore, we need to design a subcontracting device to solve these problems. Utility Model Content

[0005] The problem to be solved by this utility model is to provide a sub-packaging device.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A subcontracting device includes a column, a sliding frame fitted on the column, a fixed handle on the sliding frame, a lifting cover slidably mounted on the sliding frame, a lifting groove on the sliding frame located inside the lifting cover, a rotating wheel rotatably mounted inside the lifting cover, a lifting column fixedly mounted on the rotating wheel, the lifting column located within the lifting groove, a drive arm rotatably mounted on the lifting cover, a return torsion spring between the drive arm and the lifting cover, a friction wheel rotatably mounted on the drive arm, a drive wheel and a driven wheel interconnected within the drive arm, the diameter of the drive wheel not exceeding the diameter of the driven wheel, the drive wheel connected to the friction wheel, the driven wheel connected to the rotating wheel, a mounting plate on the lifting cover, a telescopic mechanism at the bottom of the mounting plate, and a pressure plate connected to the telescopic mechanism.

[0008] Preferably, the drive arm is rotatably connected to the lifting cover via a connecting pipe, the reset torsion spring is fitted onto the connecting pipe, and one end of the reset torsion spring is connected to the drive arm, while the other end of the reset torsion spring is connected to the lifting cover.

[0009] With this setup, the drive arm can be reset via the reset torsion spring, while ensuring that the friction wheel and the carton are always in close contact.

[0010] Preferably, the number of telescopic mechanisms is at least one, and a reinforcing plate is also provided between the telescopic mechanism and the mounting plate.

[0011] This configuration increases the stability of the connection between the pressure plate and the mounting plate.

[0012] Preferably, the telescopic mechanism includes a mounting tube fixedly mounted on the mounting plate. A limit block, a pressure block, and a spring are disposed inside the mounting tube. The spring is located between the pressure block and the limit block. A telescopic rod is fixedly mounted on the limit block. The free end of the telescopic rod extends from the mounting tube and is connected to the pressure plate. An adjusting bolt is disposed through the mounting plate. One end of the adjusting bolt extends into the mounting tube and is rotatably connected to the pressure block.

[0013] This design ensures sufficient friction between the pressure plate and the carton, while preventing damage to the carton due to excessive downward movement of the pressure plate.

[0014] Preferably, a slide rail is fixedly provided on the sliding frame, and the lifting cover is slidably connected to the sliding frame through the slide rail.

[0015] This design ensures the stability of the connection between the lifting cover and the sliding frame, while also limiting the direction of movement of the lifting cover.

[0016] Preferably, the drive wheel is connected to the friction wheel via a rotating shaft, and the driven wheel is connected to the rotating wheel via a transmission shaft.

[0017] This configuration enables the transmission of power from the friction wheel to the rotating wheel.

[0018] Preferably, the friction wheel is a rubber wheel and the pressure plate is a nylon plate.

[0019] With this setup, the rubber friction wheel can ensure normal rotation after contacting the carton, while the nylon pressure plate has sufficient mechanical strength to exert pressure on the carton support.

[0020] Preferably, a bearing is fixedly mounted on the lifting column, the outer diameter of the bearing is the same as the width of the lifting groove, and the length of the lifting column does not exceed the depth of the lifting groove.

[0021] This design reduces friction between the lifting column and the lifting channel, minimizing wear and extending service life.

[0022] Preferably, the fixed handle and the sliding frame are threaded together, and the adjusting bolt and the mounting plate are threaded together.

[0023] With this configuration, the threaded engagement between the fixed handle and the sliding bracket allows the sliding bracket to be fixed on the column, while the threaded engagement between the adjusting bolt and the mounting plate allows the pressure of the spring inside the mounting tube to be adjusted.

[0024] The advantages and positive effects of this utility model are:

[0025] This invention utilizes an adjustable sliding frame added to the column to accommodate the packaging of cartons of different sizes. The friction wheel, in contact with the cartons, drives the lifting hood to move up and down. A pressure plate connected to the lifting hood squeezes the cartons, gradually increasing and then decreasing the friction between the cartons and the pressure plate, thus causing the cartons to move relative to the conveyor belt. This enables the packaging of adjacent cartons on the conveyor belt. Furthermore, this packaging mechanism relies on the friction between the friction wheel and the cartons, along with mechanical transmission components, to achieve the packaging of cartons, eliminating the need for an electrical control system and improving operational flexibility.

[0037] The present invention will be further described below with reference to the accompanying drawings:

[0038] Example 1: As Figures 1-6As shown, a subcontracting device includes a column 1, a sliding frame 2 mounted on the column 1, a fixed handle 3 on the sliding frame 2, a lifting cover 6 slidably mounted on the sliding frame 2, a lifting groove 5 on the sliding frame 2 located inside the lifting cover 6, a rotating wheel 7 rotatably mounted inside the lifting cover 6, a lifting column 8 fixedly mounted on the rotating wheel 7, the lifting column 8 located inside the lifting groove 5, a driving arm 12 rotatably mounted on the lifting cover 6, a return torsion spring 11 between the driving arm 12 and the lifting cover 6, a friction wheel 17 rotatably mounted on the driving arm 12, a driving wheel 14 and a driven wheel 13 interconnected inside the driving arm 12, the diameter of the driving wheel 14 not exceeding the diameter of the driven wheel 13, the driving wheel 14 connected to the friction wheel 17, the driven wheel 13 connected to the rotating wheel 7, a mounting plate 21 on the lifting cover 6, a telescopic mechanism at the bottom of the mounting plate 21, and a pressure plate 23 connected to the telescopic mechanism.

[0039] Preferably, the drive arm 12 is rotatably connected to the lifting cover 6 via the connecting pipe 10, and the reset torsion spring 11 is fitted onto the connecting pipe 10. One end of the reset torsion spring 11 is connected to the drive arm 12, and the other end of the reset torsion spring 11 is connected to the lifting cover 6. This arrangement allows the drive arm 12 to be reset via the reset torsion spring 11, while ensuring that the friction wheel 17 and the carton 19 are always in close contact.

[0040] Preferably, the number of telescopic mechanisms is at least one, and a reinforcing plate 26 is provided between the telescopic mechanism and the mounting plate 21. This arrangement can increase the connection stability between the pressure plate 23 and the mounting plate 21.

[0041] Preferably, the telescopic mechanism includes a mounting tube 27 fixedly mounted on the mounting plate 21. A limit block 28, a pressure block 29, and a spring 24 are provided inside the mounting tube 27. The spring 24 is located between the pressure block 29 and the limit block 28. A telescopic rod 22 is fixedly mounted on the limit block 28. The free end of the telescopic rod 22 extends from the mounting tube 27 and is connected to the pressure plate 23. An adjusting bolt 25 is provided through the mounting plate 21. One end of the adjusting bolt 25 extends into the mounting tube 27 and is rotatably connected to the pressure block 29. This arrangement ensures the friction between the pressure plate 23 and the carton 19, and avoids damage to the carton 19 due to excessive downward movement of the pressure plate 23.

[0042] Preferably, a slide rail 4 is fixedly installed on the sliding frame 2, and the lifting cover 6 is slidably connected to the sliding frame 2 through the slide rail 4. This arrangement ensures the stability of the connection between the lifting cover 6 and the sliding frame 2, and also limits the direction of movement of the lifting cover 6.

[0043] Preferably, the drive wheel 14 is connected to the friction wheel 17 via a rotating shaft 16, and the driven wheel 13 is connected to the rotating wheel 7 via a transmission shaft 9. This arrangement enables the transmission of power from the friction wheel 17 to the rotating wheel 7.

[0044] Preferably, the friction wheel 17 is a rubber wheel and the pressure plate 23 is a nylon plate. This arrangement of the rubber friction wheel 17 ensures normal rotation after contact with the carton 19, while the nylon pressure plate 23 has sufficient mechanical strength to exert pressure on the support of the carton 19.

[0045] Preferably, a bearing 20 is fixedly mounted on the lifting column 8. The outer diameter of the bearing 20 is the same as the width of the lifting groove 5, and the length of the lifting column 8 does not exceed the depth of the lifting groove 5. This arrangement can reduce the friction between the lifting column 8 and the lifting groove 5, reduce wear, and extend service life.

[0046] Preferably, the fixed handle 3 and the sliding frame 2 are connected by threads, and the adjusting bolt 25 and the mounting plate 21 are connected by threads. This setting of the fixed handle 3 and the sliding frame 2 threaded connection can fix the sliding frame 2 on the column 1, and the adjusting bolt 25 and the mounting plate 21 threaded connection can adjust the pressure of the spring 24 in the mounting tube 27.

[0047] The working process of this embodiment: Refer to Figure 1 As shown, before use, first adjust the position of the sliding frame 2 on the column 1 so that the lifting cover 6 is in the upper limit position (i.e., Figure 3-1 When the friction wheel 17 is at the position shown, the height of the transmission belt 15 is slightly lower than the height of the carton 19. Then, the sliding frame 2 is fixed by the fixed handle 3. When the cartons 19 that are in contact with each other move along the conveyor belt 18, the friction wheel 17 will rotate. After the friction wheel 17 rotates, it will drive the drive wheel 14 to rotate through the rotating shaft 16. After the drive wheel 14 rotates, it will drive the driven wheel 13 to rotate through the transmission belt 15. After the driven wheel 13 rotates, it will drive the transmission shaft 9 to rotate. After the transmission shaft 9 rotates, it will drive the rotating wheel 7 to rotate. When the rotating wheel 7 rotates, it will drive the lifting column 8 to move. When the lifting column 8 moves, since the position of the lifting groove 5 remains unchanged, the rotating wheel 7 will start to move under the drive of the reaction force. The lifting cover 6 is slidably installed on the sliding frame 2, so when the rotating wheel 7 moves, the lifting cover 6 will start to move along the slide rail 4.

[0048] Reference Figure 3 As shown, the positions of the lifting cover 6 and the friction wheel 17 in the initial state are as follows: Figure 3 As shown in 3-1, after the friction wheel 17 rotates, the lifting column 8 on the rotating wheel 7 will rotate to the position shown in Figure 3-1. Figure 3 As shown in Figure 3-2, the drive arm 12 has shifted, the return torsion spring 11 is compressed, and as the friction wheel 17 continues to rotate, the lifting cover 6 gradually moves to the position shown in Figure 3-2. Figure 3 The state shown in 3-3 is then moved to the state shown in Figure 3-3. Figure 3 The state shown in 3-4 will eventually become Figure 3As shown in Figure 3-1, the compressed reset torsion spring 11 will drive the drive arm 12 to reset.

[0049] As the lifting cover 6 moves downward, the pressure plate 23 also moves downward synchronously and contacts the top of the adjacent carton 19. After the pressure plate 23 contacts the top of the carton 19, it stops moving. As the lifting cover 6 moves downward, the mounting plate 21 presses down on the mounting tube 27, compressing the spring 24 located between the pressure block 29 and the limiting block 28. After the spring 24 is compressed, it pushes the pressure plate 23 through the telescopic rod 22, gradually increasing the pressure of the pressure plate 23 on the carton 19. As the friction between the pressure plate 23 and the carton 19 increases, the carton 19 will slide relative to the conveyor belt 18 because the conveying speed of the conveyor belt 18 remains constant. This causes the moving speed of the carton 19 to gradually decrease to less than the moving speed of the transmission belt 15 and eventually stop. When the lifting cover 6 starts to move upward from the lowest point, the pressure applied to the carton 19 by the pressure plate 23 gradually decreases, and the movement of the carton 19 gradually resumes, and the moving speed gradually increases until it is the same as the moving speed of the conveyor belt 18 again.

[0050] During the above process, the speed of the cardboard box 19, which has already passed under the friction wheel 17, does not decrease. Therefore, a gap will appear after the cardboard box 19 passes the friction wheel 17, realizing the separation of the cardboard box 19. The pressure applied to the cardboard box 19 by the pressure plate 23 is as follows: Figure 3 As shown, the pressure gradually increases and then decreases as the height of the lifting cover 6 changes.

[0051] In this embodiment, the position of the pressure block 29 in the mounting tube 27 can be adjusted by rotating the adjusting bolt 25, thereby adjusting the elastic force of the spring 24. This ensures that the friction between the pressure plate 23 and the carton 19 after squeezing the carton 19 is greater than the friction between the carton 19 and the conveyor belt 18, so that the moving speed of the carton 19 will gradually decrease and stop before recovering, thus realizing the packaging of adjacent cartons 19.

[0052] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
