Description

Pressing and transferring mechanism for compressed towels

Technical Field

The invention relates to packaging equipment, in particular to a material pressing and transferring mechanism for compressed towels.

Background Art

The transfer mechanism is an important part of the compressed towel machine. It is used for batch transfer operations of compressed towels. The Chinese patent document (Announcement No.: CN 115230222 B; Announcement Date: April 25, 2023) discloses an automatic filling and transfer device for compressed towel production, including a base plate, characterized in that: a rotating device is provided on the upper surface of the base plate, and a plurality of transition molds are fixedly installed on the rotating device, and the rotating device drives the transition mold 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, and the driving device drives the pressing rod to move in the up and down and left and right directions and press the non-woven fabric into each hole position in the transition mold under the rotation movement of the transition mold; an ejector rod matching the number of holes in the transition mold is also provided above the unloading point of the base plate, and the ejector rod ejects the non-woven fabric pressed into the transition mold, and 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 defects of the above transfer device are: 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 group of holes in the transition mold. The movement of the pressing rod is relatively complicated, and the towel can only be pressed into one hole at a time, which is inefficient. In addition, the transition mold is set on a chain. Since the pressing rod moves left and right in the horizontal direction, it is necessary to design the holes on the transition mold to be arranged in a straight line. This straight line arrangement of holes requires that after each row of holes is loaded, the transition mold needs to be controlled to move horizontally by the spacing distance of a row of holes. This makes the moving path of the transition mold include horizontal movement at the pressing station and rotation to the ejecting station to eject the towel, resulting in a long moving path of the transition mold, which will also affect the overall transfer efficiency. At the same time, its rotating device adopts an upper and lower chain structure. In long-term work, the chain is easy to stretch, causing the transition mold to be out of place during the rotation process, and will collide with the pressing rod, resulting in the phenomenon of being unable to press the material.

DETAILED DESCRIPTION

As shown in the figure, the pressing and transferring mechanism of the compressed towel disclosed in the present invention includes an arranged pressing rod 7, which is connected to a first lifting drive assembly. In the present embodiment, each pressing rod 7 is connected to a corresponding first lifting drive assembly, which includes a first motor 1, and 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, and the other end of the transmission arm 3 is hinged to a lifting seat 6, a slide seat 4 is provided on the lifting seat 6, and a slide rail 5 cooperating with the slide seat 4 is provided on the frame, and each pressing rod 7 is installed on the 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 rod 7 to be lifted and lowered under the guidance of the slide rail 5. A first rotating plate 14 and a second rotating plate 9 are provided below the press rod 7. The first rotating plate 14 is connected to the first rotating drive assembly, and the second rotating plate 9 is connected to the second rotating drive assembly. Transfer molds 12 are installed on both the first and second rotating plates. A bottom plate 15 is provided below the transfer mold 12. The transfer mold 12 has a fan-shaped arrangement of placement cavities, and the number of placement cavities 13 in each placement cavity group corresponds to the number of the press rod 7. Further, a first connecting portion 8 and a second connecting portion 11 are extended on the second rotating plate 9. Transfer molds 12 are installed on 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 provided on the rotating plate, thereby increasing the number of transfer molds on the entire rotation path, thereby improving the transfer efficiency. Specifically, the angle between the first connection part 8 and the second connection part 11 is 90 degrees. This angle setting makes the layout of the first and second rotating plates more uniform, and the first and second rotating drive components control the first and second rotating plates to rotate and drive the transfer mold 12 to transfer to different stations. The required rotation angles are roughly the same. Of course, the angle between the first and second connection parts can also be set to other angles, and then the first and second rotating drive components are set by the program 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, and the first rotating plate 14 and the second rotating plate 9 are arranged up and down. A discharge clearance groove is provided on the bottom plate 15, and a discharge rod 17 is provided above the discharge clearance groove. The discharge rod 17 corresponds to the number and position of the storage cavity 13 on the transfer mold 12. The discharge rod 17 is arranged on the mounting plate 16, and the mounting plate 16 is connected to the second lifting drive assembly. In this embodiment, the second lifting drive assembly is a linear motor 18. A rotating disk 19 is arranged below the bottom plate 15, and 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 and meshes with a transmission gear. The transmission gear is connected to a 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 a corresponding position. The subsequent pressing mechanism presses the towels out of the pressing mold 27 to collect the compressed towels. The first rotating drive assembly includes a second motor 20, the output end of the second motor 20 is connected to a first gear 21, the first gear 21 is meshed with a second gear 22, the second gear 22 is connected to a drive sleeve 23, and the drive sleeve 23 is connected to the first rotating plate 14. The second rotating drive assembly includes a third motor 26, the output end of the third motor 26 is connected to a third gear 25, the third gear 25 is meshed with a fourth gear 24, and the fourth gear 24 is connected to a drive shaft 10. The drive shaft 10 passes through the drive sleeve 23 and is connected to the second rotating plate 9.

The working principle of the present invention is as follows: by controlling the second rotating plate 9 to rotate, the transfer mold 12 on the second rotating plate 9 is rotated to the pressing station. When one row of the storage cavity groups rotates to the bottom of the arranged pressing rods 7, the pressing rods 7 are aligned with each storage cavity 13. At this time, the storage cavity group, the pressing rod and the driving shaft 10 are on the same plane. As the compressed towel is transported to the top of the corresponding storage cavity 13, the corresponding pressing rod 7 is controlled to descend to press the towel into the storage cavity 13. Then, the second rotating plate 9 is controlled to rotate an angle of the spacing between the storage cavity groups, driving the transfer mold 12 to rotate so that the next group of adjacent storage cavity groups rotates to align with the pressing rod 7 for pressing. At this time, the storage cavity group The cavity group, the pressing rod and the driving shaft 10 are also on the same plane until towels are pressed in all the storage cavities 13 on the transfer mold 12. When the transfer mold on the second rotating plate 9 is pressing the material, the transfer mold on the first rotating plate 14 that has been pressed with the towel will rotate to the unloading station along with the first rotating plate 14, and the towel will be pressed into the pressing mold 27 on the rotating disk 19 by controlling the unloading rod 17 to descend, and the towel will be transferred. Then the first rotating plate 14 is controlled to rotate so that its empty transfer mold 12 rotates to the pressing station to press the towel. At the same time, the second rotating plate 9 drives the transfer mold that has been loaded with towels to rotate to the unloading station for unloading operation, and the pressing and transferring of the towels are carried out in this cycle.

This structure of the present invention arranges and sets pressing rods, and the number of storage chambers in each storage chamber group corresponds to the number of pressing rods. It only needs to control the pressing rods to rise and fall to complete the towel pressing operation of each storage chamber group, and there is no need to control the pressing rods to move horizontally, thereby reducing the action time of the pressing rods and improving the pressing efficiency. In addition, the storage chamber groups are arranged in a fan-shaped arrangement, and the transfer mold is set on a rotating plate. It only needs to control the rotating plate to drive the transfer mold to rotate. When the storage chamber group on the transfer mold rotates to the bottom of the pressing rod, it can be directly aligned with the pressing rod. There is no need to control the transfer mold to move in a straight line during the pressing process, which effectively shortens the moving stroke of the transfer mold within a transfer cycle, thereby improving the overall transfer efficiency of the equipment, and making the equipment structure simpler and the overall volume smaller, which is convenient for the installation and layout of the equipment.
