Description

Technical Field

[0001] This invention relates to the field of pipeline cleaning technology, and in particular to a cleaning device for pipelines used in the production and transportation of paper containers. Background Technology

[0002] Paper container conveying pipelines are specialized material conveying systems designed for high-speed transport of products during production. They are primarily used to rapidly, continuously, and stably transport various sizes of paper containers, such as paper cups, bowls, boxes, and lids, during the forming process. The upper and lower openings of these containers require lubrication during forming. Since paper containers are made of paper, some paper lint may be generated at the edges. When these containers are transported through the pipeline after forming, any accompanying white oil and any paper lint can easily remain on the inner wall of the pipeline. Because the pipeline is cylindrical, either straight or curved, and is constructed from a combination of seamless resin pipes and ventilated stainless steel pipes, it is suspended at height and difficult to disassemble. The pipeline is not sealed, and especially when the machine is shut down for a period of time, dust and residue can easily accumulate on the inner wall. Upon restarting, these residues can contaminate the transported paper containers, affecting their appearance and quality. Existing pipeline installations span multiple devices or different devices and areas, and the pipelines are quite long. Currently, there are no suitable tools for manual or automatic cleaning. The only solution is to use a batch of paper containers to quickly transport the pipeline before starting the machine. The inertia of the rapid transport carries away the residue in the pipeline along with the paper containers. After the pipeline is cleaned, mass production begins. The paper containers are essentially pipeline cleaning tools. After cleaning, they are all disposed of as scrap. This current solution is labor-intensive, time-consuming, and material-intensive, resulting in waste of finished products and increased production costs.

[0003] In view of this, the present invention is hereby proposed. Summary of the Invention

[0023] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-8 As shown, this embodiment provides a cleaning device for a paper container production conveying pipeline, including an installation block 1. A limiting groove is formed on the installation block 1, and a take-up / release drive assembly 2 is installed in the limiting groove. A first arc-shaped bonding block 3 and a second arc-shaped bonding block 4 are installed on the take-up / release drive assembly 2. The take-up / release drive assembly 2 is used to adjust the distance between the first arc-shaped bonding block 3 and the second arc-shaped bonding block 4. Both the first arc-shaped bonding block 3 and the second arc-shaped bonding block 4 are flush with the inner walls of the seamless resin pipeline 5 and the ventilated stainless steel pipeline 6. For bonding and connection, during use, the control and retraction drive component 2 is used to ensure that the outer walls of the first arc-shaped bonding block 3 and the second arc-shaped bonding block 4 are bonded to the inner walls of the seamless resin pipe 5 and the ventilated stainless steel pipe 6. Both sides of the first arc-shaped bonding block 3 and the second arc-shaped bonding block 4 have mounting slots, in which an expansion-type self-propelled component 7 is installed. The expansion-type self-propelled component 7 is used to drive the first arc-shaped bonding block 3 and the second arc-shaped bonding block 4 to move inside the seamless resin pipe 5 and the ventilated stainless steel pipe 6. When the outer wall of the composite block 3 and the second arc-shaped bonding block 4 is bonded to the inner wall of the resin seamless pipe 5 and the ventilated stainless steel pipe 6, the self-propelled expansion component 7 is controlled to make close contact with the inner wall of the resin seamless pipe 5 and the ventilated stainless steel pipe 6, and drives the installation block 1 to move inside the pipe to facilitate cleaning within the pipe. A flexible connecting strip 8 is fixedly installed on the side wall of the installation block 1, and a T-shaped connecting block 9 is installed at one end of the flexible connecting strip 8. A detachable cleaning and dust collection component 10 is installed on the T-shaped connecting block 9. When moving inside the pipe, the detachable cleaning and dust collection assembly 10 facilitates the cleaning and collection of dust and impurities on the inner wall of the pipe. The other end of the flexible connecting strip 8 is fixedly installed with a threaded head 11, and a threaded sleeve 12 is fitted onto the threaded head 11. A dust scraper 13 is fixedly installed on one end of the threaded sleeve 12, and a rear dust collection bag 14 is fixedly installed on the dust scraper 13 to scrape and collect dust and impurities on the inner wall of the pipe. The dust scraper 13 is wide at one end and narrow at the other end to collect dust into the rear dust collection bag 14.

[0024] The retraction drive assembly 2 includes a servo motor 201 and a bidirectional lead screw 202. The servo motor 201 is fixed to the inner wall of one end of the limiting slide groove. The bidirectional lead screw 202 is rotatably mounted on the inner wall of the other end of the limiting slide groove via a rotary joint 203. One end of the bidirectional lead screw 202 is fixedly connected to the output shaft of the servo motor 201. Two threaded sliders 204 are mounted on the bidirectional lead screw 202, and these sliders 204 are slidably engaged in the limiting slide groove. The two threaded sliders 204 are located at the opposite thread ends of the bidirectional lead screw 202, and a first L-shaped connecting block 205 is fixedly mounted on each of the two threaded sliders 204. The second L-shaped connecting block 206, the first arc-shaped fitting block 3, and the second arc-shaped fitting block 4 are respectively fixed on the first L-shaped connecting block 205 and the second L-shaped connecting block 206. In use, the servo motor 201 is turned on, so that the bidirectional lead screw 202 rotates in the limiting slide groove through the rotary joint 203, driving the two threaded sliders 204 to slide in opposite directions in the limiting slide groove. This allows the first L-shaped connecting block 205 and the second L-shaped connecting block 206 to move the first arc-shaped fitting block 3 and the second arc-shaped fitting block 4 to both sides, so that the first arc-shaped fitting block 3 and the second arc-shaped fitting block 4 can fit and contact the inner wall of the pipe.

[0025] The inflatable self-propelled assembly 7 includes a drive motor 701 and a drive connecting rod 702. The drive motor 701 is fixed to the inner wall of one end of the mounting slot, and the drive connecting rod 702 is rotatably mounted on the inner wall of the other end of the mounting slot. One end of the drive connecting rod 702 is fixedly connected to the output shaft of the drive motor 701. An inflatable airbag 703 is fixedly sleeved on the drive connecting rod 702, and a soft rubber sleeve 704 is fixedly sleeved on the inflatable airbag 703. A miniature air pump 705 is fixedly mounted on the inner wall of one end of the mounting slot, and an air supply pipe 706 is installed on the miniature air pump 705. The air supply pipe 706 is connected to the inflatable airbag 703 through a rotating connecting ring 707. In use, the miniature air pump 705 is turned on, and gas is introduced into the inflatable airbag 703 through the air supply pipe 706. The inflatable airbag 703 inflates, causing the soft rubber sleeve 704 to fit tightly against the inner walls of the seamless resin pipe 5 and the ventilated stainless steel pipe 6. The drive motor 701 is then activated, causing the drive connecting rod 702 to rotate the inflatable airbag 703 and the soft rubber sleeve 704. Through the friction between the soft rubber sleeve 704 and the inner walls of the seamless resin pipe 5 and the ventilated stainless steel pipe 6, the soft rubber sleeve 704 rolls on the inner walls of the seamless resin pipe 5 and the ventilated stainless steel pipe 6. This causes the first arc-shaped fitting block 3 and the second arc-shaped fitting block 4 to move within the seamless resin pipe 5 and the ventilated stainless steel pipe 6. While the soft rubber sleeve 704 rotates, the rotating connecting ring 707 is fixed by the air supply pipe 706, ensuring that the air supply operation of the air supply pipe 706 is not affected.

[0026] The detachable cleaning and dust collection assembly 10 includes an annular connecting frame 1001. A front dust collection bag 1002 is fixedly installed on one end of the annular connecting frame 1001, and a U-shaped mounting base 1003 is fixedly installed on the other end of the annular connecting frame 1001. A cleaning roller brush 1004 is rotatably installed on the U-shaped mounting base 1003, and one end of the cleaning roller brush 1004 is fixedly connected to the built-in motor output shaft of the U-shaped mounting base 1003. The annular connecting frame 1001 is sleeved on one end of a T-shaped connecting block 9. An L-shaped positioning plate 1005 is fixedly installed on the annular connecting frame 1001. A positioning pin 1006 is slidably installed on one end of the L-shaped positioning plate 1005. One end of the positioning pin 1006 is inserted into a positioning pin hole opened on the T-shaped connecting block 9, and a lifting handle 1007 is fixedly installed on the other end of the positioning pin 1006. A lifting handle 1007 is fixedly sleeved on the positioning pin 1006. An annular pad 1008 is elastically connected to an L-shaped positioning plate 1005 via a clamping spring 1009. In use, an annular connecting frame 1001 is sleeved on one end of a T-shaped connecting block 9, and under the action of the clamping spring 1009, the positioning pin 1006 is fixedly inserted into the positioning pin hole, so that the annular connecting frame 1001 and the T-shaped connecting block 9 are fixedly connected. The built-in motor of the U-shaped mounting base 1003 is controlled to turn on, so that the cleaning roller brush 1004 rotates. When the mounting strip 1 moves inside the pipe, the cleaning roller brush 1004 moves inside the pipe. During the cleaning operation, one end of the cleaning roller brush 1004 is inserted into the inside of the pipe as the running head, so as to achieve moving cleaning inside the pipe and collect the dust that falls during cleaning into the front dust collection bag 1002.
