Description

Technical Field

[0001] This invention relates to packaging equipment, and more specifically to a pressing and conveying mechanism for compressed towels. Background Technology

[0002] The transfer mechanism is an important component of a compressed towel machine. It is used for the batch transfer of compressed towels. Chinese patent document (publication number: CN 115230222 B; publication date: April 25, 2023) discloses an automatic filler transfer device for compressed towel production, including a base plate. The device is characterized by: a rotating device on the upper surface of the base plate, on which multiple transition molds are fixedly installed, and the rotating device drives the transition molds to rotate; a driving device is provided above the filling point of the base plate, and a pressing rod is installed at the power output end of the driving device. The driving device drives the pressing rod to move in the up-down and left-right directions, and, under the rotational movement of the transition molds, presses the non-woven fabric into various holes in the transition molds; an ejector rod, matching the number of holes in the transition molds, is also provided above the unloading point of the base plate, and the ejector rod ejects the non-woven fabric pressed into the transition molds for unloading; a compression transfer device is provided on one side of the base plate, and the transfer device transfers the non-woven fabric ejected from the ejector rod. The aforementioned transfer device has the following drawbacks: When the compressed towel is pushed into the transition mold, the pressing rod needs to be controlled to move up and down and left and right for each set of holes in the transition mold. The movement of the pressing rod is relatively complex, and only one hole can be pressed in at a time, resulting in low work efficiency. In addition, the transition mold is set on a chain. Since the pressing rod moves left and right in the horizontal direction, the holes on the transition mold need to be designed in a straight line. This straight-line arrangement of holes requires that after each row of holes is filled, the transition mold needs to be controlled to move horizontally by the spacing of one row of holes. This makes the movement path of the transition mold include horizontal movement at the pressing station and rotation to the ejecting station to push out the towel, resulting in a long movement path of the transition mold, which also affects the overall transfer efficiency. At the same time, its rotating device uses an up and down chain structure. During long-term operation, the chain is prone to stretching, causing the transition mold to not be in position during rotation, which may collide with the pressing rod and cause the towel to fail to be pressed. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a pressing and conveying mechanism for compressed towels to solve the above-mentioned problems.

[0004] Therefore, the present invention is implemented using the following scheme:

[0005] A pressing and conveying mechanism for compressed towels, characterized in that: it includes pressing rods arranged in an array, the pressing rods being connected to a first lifting drive assembly; a first rotating plate and a second rotating plate are arranged below the pressing rods, the first rotating plate being connected to a first rotating drive assembly, and the second rotating plate being connected to a second rotating drive assembly; a conveying mold is mounted on both the first and second rotating plates; a base plate is arranged below the conveying mold; the conveying mold has a group of storage cavities arranged in a fan shape, and the number of storage cavities in each group of storage cavities corresponds to the number of pressing rods.

[0006] Each pressing rod is connected to a corresponding first lifting drive assembly. The first lifting drive assembly includes a first motor. The output end of the first motor is connected to a rotating wheel. The rotating wheel is eccentrically hinged to one end of the transmission arm. The other end of the transmission arm is hinged to the lifting seat. The lifting seat is provided with a slide block. The frame is provided with a slide rail that cooperates with the slide block. Each pressing rod is installed on the corresponding lifting seat.

[0007] The second rotating plate extends to provide a first connecting part and a second connecting part, and a transfer mold is installed on both the first and second connecting parts. The structure of the first rotating plate is the same as that of the second rotating plate.

[0008] The included angle between the first connecting part and the second connecting part is 90 degrees.

[0009] The base plate is provided with a discharge clearance groove, and a discharge rod is provided above the discharge clearance groove. The number and position of the discharge rods correspond to the number of placement cavities on the transfer mold. The discharge rods are set on the mounting plate, and the mounting plate is connected to the second lifting drive assembly.

[0010] A rotating disk is provided below the base plate, and a pressing mold is arranged around the rotating disk. The pressing mold has the same structure as the transfer mold.

[0011] The first rotation drive assembly includes a second motor, the output end of which is connected to a first gear. The first gear meshes with the second gear, and the second gear is connected to a drive shaft sleeve. The drive shaft sleeve is connected to a first rotating plate. The second rotation drive assembly includes a third motor, the output end of which is connected to a third gear. The third gear meshes with a fourth gear, and the fourth gear is connected to a drive shaft. The drive shaft passes through the drive shaft sleeve and is connected to the second rotating plate.

[0012] The compressed towel pressing and conveying mechanism described above, by arranging pressing rods in a specific pattern, with the number of storage chambers in each set corresponding to the number of pressing rods, only requires controlling the lifting and lowering of the pressing rods to complete the towel pressing operation for each set of storage chambers. This eliminates the need to control the horizontal movement of the pressing rods, thus reducing the action time and improving pressing efficiency. Furthermore, by arranging the storage chambers in a fan shape and placing the conveying mold on a rotating plate, only the rotating plate needs to be controlled to drive the conveying mold to rotate. When the storage chambers on the conveying mold rotate to below the pressing rods, they can be directly aligned with the pressing rods, eliminating the need to control the conveying mold to move linearly during the pressing process. This effectively shortens the travel distance of the conveying mold within a conveying cycle, thereby improving the overall conveying efficiency of the equipment. It also simplifies the equipment structure, reduces its overall size, and facilitates installation and deployment. Because the chain structure is eliminated and a rotating plate drives the mold, the problem of the mold not being in place due to chain stretching, as seen in the prior art, is avoided, resulting in better stability during long-term operation.

[0019] As shown in the figure, the pressing and conveying mechanism for compressed towels disclosed in this invention includes pressing rods 7 arranged in an array. The pressing rods 7 are connected to a first lifting drive assembly. In this embodiment, each pressing rod 7 is connected to a corresponding first lifting drive assembly. The first lifting drive assembly includes a first motor 1. The output end of the first motor 1 is connected to a rotating wheel 2. The rotating wheel 2 is eccentrically hinged to one end of a transmission arm 3. The other end of the transmission arm 3 is hinged to a lifting seat 6. A slide 4 is provided on the lifting seat 6. A slide rail 5 that cooperates with the slide 4 is provided on the frame. Each pressing rod 7 is installed on a corresponding lifting seat 6. By controlling the first motor 1 to drive the rotating wheel 2 to rotate, the transmission arm 3 can drive the lifting seat 6 and the pressing rods 7 to rise and fall under the guidance of the slide rail 5. Below the pressure rod 7, a first rotating plate 14 and a second rotating plate 9 are provided. The first rotating plate 14 is connected to a first rotating drive assembly, and the second rotating plate 9 is connected to a second rotating drive assembly. Transfer molds 12 are mounted on both the first and second rotating plates. A base plate 15 is provided below the transfer molds 12. The transfer molds 12 have fan-shaped arrangement of storage cavities, with the number of storage cavities 13 in each group corresponding to the number of pressure rods 7. Furthermore, a first connecting portion 8 and a second connecting portion 11 extend from the second rotating plate 9. Transfer molds 12 are mounted on both the first and second connecting portions. The structure of the first rotating plate 14 is the same as that of the second rotating plate 9. By providing two connecting portions, two transfer molds can be installed on the rotating plate, thereby increasing the number of transfer molds along the entire rotation path and improving transfer efficiency. Specifically, the included angle between the first connecting part 8 and the second connecting part 11 is 90 degrees. This angle setting makes the arrangement of the first and second rotating plates more uniform, and the rotation angles that the first and second rotating drive components need to control when controlling the first and second rotating plates to rotate and drive the transfer mold 12 to transfer to different stations are approximately the same. Of course, the included angle between the first and second connecting parts can also be set to other angles, and the first and second rotating drive components can be programmed to drive the first and second rotating plates to rotate, ensuring that they can be accurately delivered to the pressing station and the ejecting station. The first rotating plate 14 and the second rotating plate 9 are arranged vertically. The bottom plate 15 is provided with a discharge clearance groove, and a discharge rod 17 is provided above the discharge clearance groove. The number and position of the discharge rod 17 correspond to the number of placement cavities 13 on the transfer mold 12. The discharge rod 17 is set on the mounting plate 16, and the mounting plate 16 is connected to the second lifting drive component. In this embodiment, the second lifting drive component is a linear motor 18. A rotating disk 19 is provided below the base plate 15. A pressing mold 27 is arranged around the rotating disk 19. The structure of the pressing mold 27 is the same as that of the transfer mold 12. The rotating disk 19 has external teeth that mesh with the transmission gear. The transmission gear is connected to the corresponding motor. By controlling the motor to start, the transmission gear and the rotating disk 19 are driven to rotate, so that the pressing mold 27 rotates to the corresponding position. The subsequent pressing mechanism presses the towel out of the pressing mold 27 for the collection of compressed towels.The first rotation drive assembly includes a second motor 20, the output end of which is connected to a first gear 21. The first gear 21 meshes with a second gear 22. The second gear 22 is connected to a drive shaft sleeve 23. The drive shaft sleeve 23 is connected to a first rotating plate 14. The second rotation drive assembly includes a third motor 26, the output end of which is connected to a third gear 25. The third gear 25 meshes with a fourth gear 24. The fourth gear 24 is connected to a drive shaft 10. The drive shaft 10 passes through the drive shaft sleeve 23 and is connected to the second rotating plate 9.

[0020] The working principle of this invention is as follows: By controlling the rotation of the second rotating plate 9, the transfer mold 12 on the second rotating plate 9 rotates to the pressing position. When one row of placement chambers rotates to below the arranged pressing rods 7, the pressing rods 7 are aligned with each placement chamber 13. At this time, the placement chamber group, the pressing rod, and the drive shaft 10 are on the same plane. As the compressed towel is conveyed to the top of the corresponding placement chamber 13, the corresponding pressing rod 7 is controlled to descend and press the towel into the placement chamber 13. Then, the second rotating plate 9 is controlled to rotate by an angle equal to the spacing between placement chamber groups, causing the transfer mold 12 to rotate so that the next adjacent placement chamber group rotates to align with the pressing rod 7 for pressing operation. The material cavity assembly, the pressing rod, and the drive shaft 10 are all on the same plane until all the material cavities 13 on the transfer mold 12 are filled with towels. When the transfer mold on the second rotating plate 9 is pressing the material, the transfer mold on the first rotating plate 14, which already has towels pressed on it, rotates with the first rotating plate 14 to the unloading position. By controlling the unloading rod 17 to descend, the towels are pressed into the pressing mold 27 on the rotating plate 19, and the towels are transferred. Then, the first rotating plate 14 is controlled to rotate, so that its empty transfer mold 12 rotates to the pressing position to press the towels. At the same time, the second rotating plate 9 drives the transfer mold that is already filled with towels to rotate to the unloading position for unloading. The pressing and transfer of towels are repeated in this way.

[0021] This invention features a structure where pressure rods are arranged in a specific pattern, with the number of storage chambers in each storage chamber group corresponding to the number of pressure rods. Simply raising and lowering the pressure rods is sufficient to press the towel into each storage chamber group, eliminating the need for horizontal movement and reducing the time required for the pressure rods to move, thus improving pressing efficiency. Furthermore, the storage chambers are arranged in a fan shape, and the transfer mold is mounted on a rotating plate. Controlling the rotating plate to rotate the transfer mold allows the storage chambers on the transfer mold to align directly with the pressure rods when they rotate below them, eliminating the need for the transfer mold to move linearly during the pressing process. This effectively shortens the travel distance of the transfer mold within a single transfer cycle, improving the overall transfer efficiency of the equipment. The invention also simplifies the equipment structure, reduces its overall size, and facilitates installation and deployment.
