Description

Technical Field

[0001] The utility model belongs to the technical field of paper cup knurling, and in particular relates to a knurling device for a milk tea paper cup body. Background Art

[0002] Milk tea is a very popular drink in life. In beverage shops, milk tea paper cups are usually used to hold hot milk tea. Milk tea paper cups are a kind of paper container made by mechanical processing and bonding of base paper made of chemical wood pulp. They can be used to hold water, beverages, ice cream, etc. Because they are safe, hygienic, light and convenient, they are widely used in public places such as hotels and restaurants. The paper cup is composed of a cup body and a cup bottom. In order to make the cup body and the cup bottom bond more tightly, it is usually necessary to perform knurling around the bottom of the paper cup, so that the seam between the cup body and the cup bottom of the produced paper cup is tighter.

[0003] In view of the existing patent CN202322365945.0, a paper cup forming knurling device is proposed, which can save energy and perform knurling operations on four groups of paper cup bodies at the same time. The servo motor and the rotating shaft cooperate to make the transmission gear drive the external gear fixedly connected to the transmission gear to rotate on the moving plate, and the external gear drives the four groups of internal gears to rotate at the same time. Through the connection of the connecting shaft, the four groups of rotating plates can drive the knurling wheel to rotate at the same time to perform knurling operations on the bottom of the cup body. The first hydraulic cylinder can control the moving plate to drive the knurling wheel to move up and down, and can also The cup body is more stably limited and fixed, the cup body that needs to be knurled is placed on the fixed ring and sleeved on the fixed column. The cross plate can be controlled to move up and down under the drive of the second hydraulic cylinder, and then the movable column is moved up and down inside the fixed column. This solves the technical problem that the existing device needs to control four sets of motors at the same time when performing knurling operations, which is energy-wasting and requires multiple sets of external power supply structures, reducing practicality. However, when part of the knurling wheels in the knurling mechanism 7 of the knurling equipment is damaged, the knurling mechanism 7 needs to be disassembled as a whole, which has high maintenance costs and cumbersome operations.

[0025] A fixing part is provided between the knurling mechanism 7 and the mounting block 10 for detachable connection, and the fixing part includes a groove 12 opened inside the mounting block 10, and a slide bar groove 15 is provided on the upper end surface inside the groove 12, and a slide bar 19 is provided inside the slide bar groove 15, and fixing blocks 16 are provided on both sides inside the groove 12, and a connecting rod 17 is connected above the fixing block 16, and a spring A18 is provided on one side of the connecting rod 17, and a first slider 13 is provided at the top of the connecting rod 17, and the first slider 13 is sleeved on the outside of the slide bar 19, and card grooves are provided on both sides of the inner wall of the mounting block 10, and a connecting block 9 is movably connected to the bottom of the mounting block 10, and the connecting block 9 is fixedly connected to the top of the knurling mechanism 7.

[0026] It should be noted that, in the existing knurling equipment, when one set of knurling wheels of the knurling mechanism 7 is damaged, the knurling mechanism 7 needs to be disassembled as a whole, which has high maintenance costs and cumbersome operations. Therefore, in order to solve the problem that the existing knurling equipment cannot be partially disassembled according to the knurling wheels in the damaged knurling mechanism 7, the fixing part of this scheme realizes the function of disassembling the knurling mechanism 7. The knurling mechanism 7 that can be quickly disassembled and assembled saves disassembly and assembly time, simplifies the installation process and improves work efficiency. By fixing the knurling mechanism 7 to the mounting block 10, when one set of knurling wheels of the knurling mechanism 7 is damaged, only one set of knurling wheels in the knurling mechanism 7 needs to be disassembled and repaired, and there is no need to disassemble the knurling mechanism 7 as a whole. This scheme is highly practical and can greatly save costs.

[0027] Specifically, in the present embodiment, the present scheme mainly realizes the function of disassembling the knurling mechanism 7 by setting a fixing part, and the knurling mechanism 7 that can be quickly disassembled and assembled saves the disassembly and assembly time, simplifies the installation process and improves the work efficiency, by fixing the knurling mechanism 7 to the mounting block 10, and by inserting the plug connector 11 at the top of the connecting block 9 into the groove located inside the mounting block 10, when the plug connector 11 is inserted into the groove, the connecting rods 17 on both sides of the groove slide to both sides under the force of the plug connector 11 and make the spring A18 on one side of the connecting rod 17 compressed to one side, and the first sliding block 13 at the top of the connecting rod 17 slides to both sides on the sliding rod 19 and fixes the plug connector 11 when it is inserted into the groove, and the connecting block 9 compresses the block 23 inward due to the pressure of the mounting block 10 when the connecting block 9 is inserted into the mounting block 10. The spring B22 connected to one side of the block 23 is compressed inwardly. When the block 23 reaches the slots on both sides inside the mounting block 10, the block 23 pops out and is inserted into the slot under the force of the spring B22 and penetrates the mounting block 10. When replacing, you only need to press the blocks 23 on both sides inward and then pull them downward, then the plug connector 11 will be disengaged from the springs A18 on both sides of the groove and pop out to reset the connecting rod 17. The first slider 13 also returns to its original position on the slide rod 19. When part of the knurling wheel in the knurling mechanism 7 is damaged, you only need to disassemble and repair the corresponding damaged knurling wheel in the knurling mechanism 7, and there is no need to disassemble the knurling mechanism 7 as a whole. The practicability is high and the cost can be greatly saved. At the same time, the knurling mechanism 7 with different patterns can be replaced for the cup bottom knurling, and the versatility is strong. The process of disassembling and replacing the knurling mechanism 7 is convenient and fast, thereby improving the work efficiency.

[0029] In this embodiment, when the connecting block 9 is inserted into the mounting block 10, the pressure of the mounting block 10 compresses the card block 23 inward, so that the spring B22 connected to one side of the card block 23 is compressed inward. When the card block 23 reaches the slots on both sides inside the mounting block 10, the card block 23 pops out and fits into the slot under the action of the spring B22 and passes through the mounting block 10.

[0030] In a further preferred embodiment of the present invention, Figure 1-5 As shown, a limit block 25 is installed at one end of the spring B22 that is away from each other, and both ends of the limit block 25 are fixedly connected with a second slider 24, and both sides of the open end of the spring groove 21 are penetrated by a slide groove 14 that cooperates with the second slider 24, and the other end of the limit block 25 is fixedly connected with a clamping block 23, which is clamped into the clamping groove and passes through the mounting block 10.

[0031] In this embodiment, by providing the second slider 24 and the slide groove 14, the spring B22 drives the limit block 25 to move, and at the same time, the second sliders 24 on both sides of the limit block 25 move in the slide groove 14, further improving the stability of the limit block 25 when moving.
