Description

Technical Field

[0001] This utility model belongs to the field of vacuum roller technology, and specifically relates to a vacuum roller internal cleaning device. Background Technology

[0002] A vacuum roller is a device used in industrial production, primarily for the handling, pressing, or transport of materials. It achieves its specific function by creating a vacuum inside the roller, as seen in industries such as papermaking, printing, and plastics processing. For example, in the papermaking industry, the continuous adsorption of paper during operation causes some paper scraps and other impurities to be sucked into the pores of the vacuum roller, leading to a decline in product quality and necessitating regular cleaning.

[0003] The existing utility model patent with application number 202221780751 discloses a reverse flushing device for a vacuum roller. This device flushes a large amount of cleaning liquid into the vacuum chamber of the vacuum roller to clean the holes. However, this utility model still has some shortcomings. Because the vacuum roller has dense holes, a large amount of water and sufficient water pressure are required to clean the holes. This places high demands on the water pump and consumes a lot of water. Utility Model Content

[0004] The purpose of this invention is to solve the problems of high water consumption and insufficient water pressure in the vacuum roller cleaning device described in the background art. Here, a new vacuum roller internal cleaning device is proposed, which can block some of the holes to increase water pressure for rinsing the holes, thereby reducing water consumption.

[0005] To achieve the above objectives, a technical solution is provided: a vacuum roller internal cleaning device. The vacuum roller includes a roller body and a vacuum pump. Shafts are respectively provided on both sides of the roller body, one of which has a cavity inside. Several suction holes are provided on the roller wall around the roller body. A vacuum tube is provided on one side of the roller body, and the vacuum tube is connected to the vacuum pump through a pipeline. The vacuum roller internal cleaning device includes a rotating roller, a motor, a circular track, several baffles, and several telescopic units. The motor is located in the cavity, and the output end of the motor passes through the side wall of the roller body and is connected to one end of the rotating roller. The other end of the rotating roller is connected to the circular track. The telescopic units connect the baffles and the rotating roller.

[0006] The vacuum roller internal cleaning device also includes a water injection pump and a liquid storage tank. The water inlet of the water injection pump is connected to the liquid storage tank through a pipeline, and the water outlet of the water injection pump is connected to the vacuum pipe through a pipeline.

[0007] In the above technical solution, the baffle can be pushed to fit against the inner wall of the roller to block part of the suction holes by the telescopic unit. At this time, water flow will be injected to increase the water pressure and achieve the effect of fully unblocking the suction holes. After the suction holes are cleaned, the roller can be rotated to drive the baffle to rotate and clean the other suction holes.

[0008] Furthermore, the internal cleaning device of the vacuum roller also includes a water pump and a wastewater tank. The outlet of the water pump is connected to the wastewater tank through a pipeline, and the inlet of the water pump is connected to the vacuum pipe through a pipeline.

[0009] In the above technical solution, in order to avoid damage to the vacuum roller and vacuum pump, a water pump is needed to extract and discharge the residual liquid inside the roller.

[0010] Furthermore, a first control valve is provided on the pipeline connecting the vacuum tube to the vacuum pump, a second control valve is provided on the pipeline connecting the vacuum tube to the water pump, and a third control valve is provided on the pipeline connecting the vacuum tube to the water pump.

[0011] In the above technical solution, the cleaning process of the vacuum pump is controlled by three control valves to prevent equipment damage.

[0012] Furthermore, the telescopic unit includes a cylinder and a hydraulic rod. One end of the cylinder is connected to the hydraulic rod, the cylinder is disposed inside the rotating roller, and the other end of the hydraulic rod passes through the roller wall of the rotating roller and is connected to the baffle.

[0013] In the above technical solution, the hydraulic rod is extended and retracted by a cylinder, thereby moving the baffle. A sealing ring can be added at the contact part between the hydraulic rod and the rotating roller to prevent water leakage.

[0014] Furthermore, the baffle is an arc-shaped baffle.

[0015] In the above technical solution, the curvature of the baffle can achieve complete fit with the inner wall of the roller, increasing the sealing performance.

[0016] Furthermore, cleaning brushes are provided on both sides of the baffle.

[0017] In the above technical solution, when the rotating roller is rotated, the cleaning brush can be driven to clean the inner wall of the roller and part of the suction hole.

[0018] Furthermore, each baffle is connected to two telescopic units, which are symmetrically arranged on both sides of the center of the baffle.

[0019] In the above technical solution, the symmetrical arrangement can enhance the stability of the baffle pushing.

[0020] Furthermore, the baffles are evenly spaced and distributed around the circumference of the rotating roller.

[0021] The advantages of this utility model are:

[0022] 1. This utility model can block part of the suction hole by pushing the baffle to fit against the inner wall of the roller, thereby increasing the water pressure, making the suction hole more thoroughly flushed, and thus reducing water consumption.

[0023] 2. This utility model can drive the baffle to rotate through the rotation of the roller, so as to flush all the suction holes. During the rotation process, the inner wall of the roller can be cleaned to remove impurities adhering to the inner wall and some impurities in the suction holes. Attached Figure Description

A vacuum tube 6 is provided on the left side wall of the shaft. The vacuum tube is connected to the vacuum pump through a pipeline. A first control valve 16 is provided on the pipeline.

[0032] The rotating roller is located inside the roller body, and the motor is set in the cavity. The output end of the motor passes through the left side wall of the roller body and is fixedly connected to the left end of the rotating roller. The right end of the rotating roller is slidably connected to the circular track and can rotate relative to the center of the circular track.

[0033] The telescopic unit consists of a cylinder 111 and a hydraulic rod 112. The cylinder is fixed to the inner wall of the roller. One end of the hydraulic rod is connected to the cylinder, and the other end passes through the circumferential roller wall of the roller and is fixedly connected to a baffle.

[0036] The working principle of this utility model:

After flushing, the motor is started to drive the roller to rotate, and the position of the baffle is adjusted to block the cleaned suction holes and expose the suction holes that have not yet been cleaned. The above operation is repeated until all suction holes are cleaned.

[0038] Close the second control valve, open the third control valve to extract the liquid from the roller body; close the third control valve, open the first control valve, and resume operation.
