Description

Technical Field

[0001] The utility model relates to the field of packaging equipment, in particular to a quick-detachable air suction roller. Background Art

[0002] Packaging equipment is used for the production and processing of various types of packaging bags. The base materials of some packaging bags, such as the bottom stickers of the bottom of the packaging bags, need to be cut off by a cutting mechanism during the conveying process, and then sent to the subsequent station for the bottom sticker operation. After cutting, the material is conveyed by rollers and belts, and then adsorbed and transferred by suction rollers. At present, the suction roller structure on the market generally adopts an integrated structure, one end of which is connected to the rotating drive assembly and is equipped with an end face sealing disk, and the other end is rotatably set in the bearing on the frame. The defect of this structure is that when the suction roller is damaged or needs to be repaired, cleaned, etc., it is necessary to remove the motor, end face sealing disk and other components on one side first, and then disassemble the roller, which makes its disassembly and assembly operation very troublesome and the user experience is not good.

DETAILED DESCRIPTION

[0017] Combined with Figure 1-5The utility model is described in detail with specific embodiments: the utility model includes a frame 1, a rotatable central axis 2 is provided on the frame 1, an adsorption roller 3 is sleeved on the central axis 2, and the adsorption roller 3 is locked on the central axis 2 by a locking assembly. Specifically, a threaded hole 303 is provided on the adsorption roller 3, and a screw is screwed into the threaded hole 303 and pressed against the central axis 2, thereby locking the adsorption roller 3 on the central axis 2. A detachable support member 4 is provided on the frame 1, and the support member 4 rotatably supports one end of the central axis 2. In this embodiment, the support member 4 is a flange, and a bearing is provided on the flange to rotatably support the central axis 2. The central axis 2 is connected to the output shaft of the rotating drive motor, so that the central axis 2 can rotate stably. At the same time, the support member 4 can be specifically fixedly connected to the frame 1 with bolts or screws. In this way, when the adsorption roller 3 needs to be replaced, the adsorption roller 3 can be taken out from the central axis 2 by simply removing the support member 4, and then a new adsorption roller 3 can be replaced. An end face sealing disk 6 with a negative pressure air cavity 601 is also provided between the frame 1 and the adsorption roller 3, and one end of the adsorption roller 3 is pressed on the end face sealing disk 6, and the other side of the end face sealing disk 6 is supported by the frame 1 to prevent gas from leaking from the gap between the end face sealing disk 6 and the adsorption roller 3. A plurality of air holes 301 are provided on the roller surface of the adsorption roller 3, and a plurality of axial air hole channels 302 are provided on the side of the adsorption roller 3, and each exhaust hole 301 is connected with the corresponding axial air hole channel 302. As the adsorption roller 3 rotates, the axial air hole channel 302 of the adsorption roller 3 can be connected with the negative pressure air cavity 601 in the end face sealing disk 6, and the negative pressure air cavity 601 in the end face sealing disk 6 is also connected to the negative pressure machine through the air outlet hole 605 and the air suction channel 602, so that the air holes of the adsorption roller 3 can adsorb the material, which is convenient for material transportation.

[0018] Furthermore, a sealing gasket 7 with a through groove is provided between the end face sealing disk 6 and the adsorption roller 3, and the adsorption roller 3 is pressed on the end face sealing disk 6 through the sealing gasket 7, so that when the adsorption roller 3 rotates, the wear of the adsorption roller 3 and the end face sealing disk 6 can be reduced, and the sealing gasket 7 has a through groove, so that the axial air hole channel 302 can still communicate with the air cavity of the end face sealing disk 6. In addition, a spring 5 is provided on the frame 1, and the end face sealing disk 6 can be axially movably sleeved on the shaft extended from the frame 1, and the two ends of the spring 5 are respectively against the end face sealing disk 6 and the frame 1, so that the elastic force of the spring 5 can cooperate with the frame to support the end face sealing disk 6, and the end face sealing disk 6 can be pushed toward the adsorption roller 3, so that even if the sealing gasket 7 is worn due to the continuous rotation of the adsorption roller 3, the spring 5 can always ensure that the end face sealing disk 6 and the adsorption roller 3 are in close contact.

[0019] Furthermore, an air inlet cavity 603 is provided in the end face sealing disk 6, and the air inlet cavity 603 has an air inlet hole 604 connected to the outside, so that when the axial air hole channel 302 of the adsorption roller 3 rotates to this position, the air pressure of the air hole 301 connected thereto returns to normal, allowing the material to fall off the adsorption roller 3.

[0020] Furthermore, the central shaft 2 is a hollow structure with a heat preservation channel to ensure that the adsorption roller 3 is kept at a constant temperature, thereby ensuring that the temperature is stable during material transportation, cooling the material, and preventing deformation of the material due to excessive temperature.

[0021] Furthermore, the air inlet 604 can be connected to an air pump to continuously pump air inward, so that the axial air hole channel 302 where the adsorption roller 3 rotates and the air hole 301 connected thereto can exhaust air outward, which helps the material to be separated from the adsorption roller 3.

[0022] When the suction roller 3 is operated, the suction roller 3 will suck the material, and the material will be transferred to the lower part of the suction roller 3 as the suction roller 3 rotates. At this time, the axial pore channel 302 of the suction roller 3 rotates to the air inlet chamber 603 of the end face sealing disk 6, so that the axial pore channel 302 at this position is connected with the air inlet chamber 603, and the air pressure is restored, so that the material falls off the suction roller 3 and is transported to the conveying bag below to send the material to the next station. Furthermore, if the air inlet hole 604 of the air inlet chamber 603 is connected to the air pump, the connected axial pore channel 302 and pore 301 can be exhausted to the outside, so as to ensure that the material can successfully separate from the suction roller 3 and cooperate with the roller below to be sent to the next station.

[0023] When the adsorption roller 3 needs to be replaced, it is only necessary to stop the machine, remove the support 4, and remove the fixing screws of the adsorption roller 3 and the central shaft 2. In this way, the adsorption roller 3 can be pulled out from the central shaft. There is no need to remove the central shaft 2 and related components associated with the central shaft 2 as in the traditional way, such as the end face sealing disk 6 and the fixing seat 5 at the other end. This greatly reduces the difficulty of disassembly and the time and labor costs required for repeated disassembly and assembly.

[0024] In summary, the utility model provides a quick-detachable suction roller, which splits the traditional integrated suction roller structure into a center axis, a suction roller and a locking assembly, and provides a detachable support member to rotatably support one end of the center axis. The suction roller can be pulled out from the center axis by only removing the support member and loosening the locking assembly, and the suction roller can be replaced, cleaned or repaired, which greatly reduces the difficulty of disassembling and assembling the suction roller and improves the user experience.
