Description

A paper card folding mechanism for a sock packaging machine Technical Field

[0001] This application relates to the field of sock packaging machine technology, and in particular to a paper card folding mechanism for a sock packaging machine. Background Technology

[0002] A sock packaging machine is an automated device specifically designed for sock packaging. Its main functions include sock conveying, cardboard conveying, hooking and folding, sewing, bagging, and sealing. Sock packaging machines are primarily used in the textile industry, meeting market demands for efficient and standardized sock packaging.

[0003] Chinese invention patent application number 201810439812.4—a paper card hook folding mechanism for a sock packaging machine—includes a frame, a paper card feeding device, a hook device, and a paper card folding device. The paper card feeding device includes a paper card conveying hole, a paper card placement hook hole, a paper card suction and translation mechanism, and a paper card placement and fixing device below the paper card conveying hole, all located on a support surface. The hook device includes a vibrating plate, a hook rod connected to the vibrating plate, and a hook-taking and flipping structure located below the support surface. The paper card folding device includes a 90-degree folding structure and a 180-degree folding structure.

[0004] The aforementioned patent application describes a paper card hook folding mechanism for sock packaging machines. This mechanism automatically transports, hooks, attaches, and folds the paper cards, making the entire process convenient and quick. However, the folding device in this patent first folds the paper card vertically at a 90-degree angle, then folds it horizontally at a 180-degree angle to complete the folding. This method cannot fold the paper card in one operation, resulting in low folding efficiency. Summary of the Invention

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this utility model. The specific implementation scheme of this utility model is as follows:

[0030] A paper card folding mechanism for a sock packaging machine includes a machine plate 1, a mounting plate 2 fixedly mounted on the machine plate 1, a folding plate 3 rotatably mounted on the mounting plate 2, a drive shaft 4 rotatably mounted on the machine plate 1, the drive shaft 4 being fixedly connected to the folding plate 3, a drive mechanism 5 for driving the folding plate 3 to rotate on one side of the folding plate 3, two pneumatic grippers 6 for fixing the paper card on the machine plate 1, and a paper card conveying device 7 on the upper part of the machine plate 1. By setting the folding plate 3 and the drive mechanism 5, the drive mechanism 5 drives the folding plate 3 to directly fold the paper card 18 in one step, avoiding the multi-step operation of first folding the paper card vertically and then horizontally, thus improving the paper card folding efficiency.

[0031] It should be noted that the drive mechanism 5 includes a motor 51, gear A52, rack 53 and gear B54. Gear B54 is keyed to the drive shaft 4 and meshes with the rack 53. The rack 53 is provided with a base 8 in a sliding structure. The base 8 is fixedly connected to the machine plate 1. The rack 53 is meshed with gear A52. The output end of the motor 51 is provided with a drive shaft 9 in a fixed structure. The drive shaft 9 is keyed to gear A52. This structure is mainly used to drive the folding plate 3 to move, thereby folding the paper card.

[0032] It should be noted that a rubber pad 10 is fixedly installed on the inner end face of the pneumatic gripper 6; the pneumatic gripper 6 is mainly used to fix the paper card for a short time to ensure that the paper card can be folded smoothly, and the design of the rubber pad 10 can avoid damage to the edge of the paper card.

[0033] It should be noted that a sock paper card clamping and conveying device 11 is fixedly installed on the upper surface of the machine plate 1. The sock paper card clamping and conveying device 11 includes a slide 110, a first cylinder 111, a gripper assembly 112, and a second cylinder 113. The slide 110 is fixedly installed on the upper surface of the machine plate 1. A mounting base 12 is slidably installed on the slide 110. The mounting base 12 is fixedly connected to the first cylinder 111. A connecting plate 13 is fixedly installed at the output end of the first cylinder 111. A second cylinder 113 is fixedly installed on the connecting plate 13. The output end of the second cylinder 113 is fixedly connected to the gripper assembly 112. The first cylinder 111 and the second cylinder 113 drive the gripper assembly 112 to clamp the sock and paper card before the folding plate 3 resets, and convey them to the next station to ensure that the paper card is folded smoothly and the sock and paper card are conveyed as a whole.

[0034] Furthermore, the gripper assembly 112 includes an upper gripper 1121 and a lower gripper 1122. The lower end face of the upper gripper 1121 and the upper end face of the lower gripper 1122 are fixedly provided with soft toothed pads 14. This structure design further ensures the stability of the gripping, prevents the socks and paper cards from sliding or falling off during the conveying process, and effectively protects the surface of the paper cards.

[0035] It should be noted that a belt conveyor 15 for conveying socks is provided on one side of the machine plate 1; this structure is designed to convey socks to a designated position.

[0036] It should be noted that the machine plate 1 is equipped with a sock-transfer gripper device 16, which is slidably connected to the machine plate 1; this structure is used to transport socks from the belt conveyor 15 to the paper card.

[0037] It should be noted that an angle sensor 17 is provided on one side of the folding plate 3, and the angle sensor 17 is connected to the signal of the external control system. This setting is used to monitor the angle position of the folding plate 3 in real time, so that the external control system can send a signal to the sock paper card clamping and conveying device 11, so that it clamps and fixes the sock and paper card before the folding plate 3 resets.

[0038] It should be noted that the paper card conveying device 7 is existing technology.

[0039] The working principle and process of this utility model are as follows:

[0040] First, the paper card conveying device 7 places the paper card at the designated position on the machine plate 1 (between the two pneumatic grippers 6), and then activates the two pneumatic grippers 6, which press down on the middle of the paper card. Simultaneously, the belt conveyor 15 is activated to transport the sock. Next, the sock-shifting gripper device 16 is activated, transporting the sock from the tail end of the belt conveyor 15 to above the paper card and pressing it onto the paper card. At this point, the two pneumatic grippers 6 return to their original positions. Then, the motor 51 is activated, rotating clockwise. The motor 51 drives the drive shaft 9 to rotate, which in turn drives the gear A52. The rotation of gear A52 drives the rack 53 to slide along the mounting base 12, which in turn drives the gear B54 to rotate. The rotation of gear B54 drives the drive shaft 4 to rotate, which in turn drives the folding plate 3 to rotate counterclockwise upwards, thus flipping the paper card. The angle sensor 17 constantly monitors the angle of the folding plate 3. When the folding plate 3 moves to the set angle value, the angle sensor 17 transmits a signal to the external control system. The external control system feeds back the signal to the sock paper card clamping and conveying device 11, which then starts working. Specifically, the first cylinder 111, which is used to horizontally drive the connecting plate 13, is activated, driving the connecting plate 13 to move until the upper clamp 1121 and the lower clamp 1122 are respectively above and below the paper card. The second cylinder 113 drives the upper clamp 1121 to move down and the lower clamp 1122 to move up until the upper clamp 1121 and the lower clamp 1122 clamp the sock and the paper card. Then, the motor 51 reverses, and the drive mechanism 5 drives the folding plate 3 to rotate clockwise for reset. Finally, the sock paper card clamping and conveying device 11 transports the sock and the paper card as a whole to the next workstation.
