DETAILED DESCRIPTION

[0025] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the embodiments of the present application, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented. The division of the following embodiments is for the convenience of description, and the specific implementation of the present application should not be construed as any limitation, and the various embodiments can be combined with each other and quoted from each other without contradiction.

[0026] Reference Figure 1-Figure 4 As shown, an embodiment of the present application provides an online roller surface cleaning device, comprising: a guide rail portion 1, a sliding portion 2, a roller surface wiping portion 3 and a power portion 4, wherein both ends of the guide rail portion 1 are respectively fixed to a trough body 10 by utilizing flanges; the sliding portion 2 is slidably connected to the guide rail portion 1, and slides along the guide rail direction of the guide rail portion 1; the roller surface wiping portion 3 is installed on the sliding portion 2, and moves synchronously with the sliding portion 2; the power portion 4 is used to control the sliding portion 2 to slide back and forth along the guide rail direction of the guide rail portion 1.

[0027] In this embodiment, a guide rail portion 1 is added between the two trough bodies 10 to provide support through the guide rail portion 1, and a sliding portion 2 that can be slidably arranged is added to the guide rail portion 1. The sliding portion 2 can move synchronously with the roller surface wiping portion 3 during the reciprocating sliding process. Therefore, the roller surface wiping portion 3 can automatically clean the roller surface of the roller to be cleaned during the reciprocating sliding process. This method does not require the entry of personnel. Compared with manual cleaning, this method is simple to operate, highly efficient, has a good cleaning effect, and is highly safe. It solves the problem of low efficiency, poor safety, and unstable wiping effect caused by simple manual wiping, which in turn leads to uncertainty in film production quality.

[0028] Please continue to refer to Figure 1-Figure 4 As shown, in this embodiment, it should be noted that the guide rail portion 1 is provided with a plurality of guide rails 11 on the side facing the roller surface to be cleaned, and the plurality of guide rails 11 are staggeredly installed on the guide rail portion 1. The staggered installation method can prevent the sliding portion 2 sliding thereon from causing stress damage to the guide rail portion 1, and then the roller surface wiping portion 3 can smoothly perform linear reciprocating motion on the guide rail 11. The guide rail 11 is extended along the length direction of the guide rail portion 1, and the guide rail 11 can be set as a V-shaped guide rail. At the same time, the guide rail portion 1 can also be applied to different trough bodies 10 by changing the length of the guide rail portion 1.

[0029] The sliding part 2 includes a side sliding part 21 and a top sliding part 22 connected to the side sliding part 21. The side sliding part 21 is arranged on the side of the guide rail part 1 facing the roller surface to be cleaned, and is slidably connected to the guide rail 11 of the guide rail part 1; the top sliding part 22 is also slidably arranged on the top surface of the guide rail part 1, and the roller surface wiping part 3 is installed on the top sliding part 22. In one example, the side sliding part 21 is provided with a roller group 23, and is arranged in two rows, the upper and lower rows of roller groups 23 are clamped on the guide rail 11 of the guide rail part 1, and then the side sliding part 21 can stably slide along the length direction of the guide rail 11. Preferably, the rollers in the roller group 23 are made of high-strength engineering plastic materials, which can not only achieve the required functions, but also play an explosion-proof role and reduce the weight of the overall component.

[0030] In the present embodiment, it is also necessary to explain that the roller surface wiping portion 3 includes a roller surface cleaning mechanism 31 and a spring mechanism 32; the roller surface cleaning mechanism 31 is slidably installed on the top surface sliding portion 22, and the roller surface cleaning mechanism 31 slides on the top surface sliding portion 22 along a sliding direction perpendicular to the sliding portion 2, that is, the roller surface cleaning mechanism 31 has two actions in the X direction and the Y direction at the same time. In the present embodiment, the roller surface cleaning mechanism 31 is positioned to slide along the length direction of the guide rail portion 1 along the X direction, and the sliding direction on the top surface sliding portion 22 is defined as the Y direction.

[0031] The spring mechanism 32 is also installed on the top surface sliding part 22. The spring mechanism 32 is extended and retracted along the Y direction. One end of the spring mechanism 32 is fixed on the top surface sliding part 22 and the other end is fixed on the roller surface cleaning mechanism 31. The spring mechanism 32 is mainly used to push the roller surface cleaning mechanism 31 forward or retract along the Y direction.

[0032] In this embodiment, the sliding portion 2 is defined as the initial position of the roller surface cleaning mechanism 31 when it is at the end of the guide rail portion 1. At the initial position, the roller surface cleaning mechanism 31 is in a non-working state. When the sliding portion 2 is slid along the guide rail portion 1 to the position where the roller surface cleaning mechanism 31 corresponds to the position of the roller surface to be cleaned, it is defined as a working position. At the working position, the roller surface cleaning mechanism 31 is in a working state.

[0033] Thus, the top surface of the guide rail portion 1 is provided with an axial cam 12 at the initial position corresponding to the roller surface cleaning mechanism 31, and the axial cam 12 is extended along the length direction of the guide rail portion 1. The bottom of the roller surface cleaning mechanism 31 is provided with a guide portion 33 that penetrates the top surface sliding portion 22, and the guide portion 33 cooperates with the axial cam 12. When the roller surface cleaning mechanism 31 is in the initial position, the guide portion 33 abuts against the raised position of the axial cam 12, and the roller surface cleaning mechanism 31 will also compress the spring mechanism 32 at this time. When the roller surface cleaning mechanism 31 follows the top surface sliding portion 22 to slide along the X direction, the guide portion 33 will move along the axial direction of the axial cam 12 at this time. When the guide portion 33 moves to the recessed position abutting against the axial cam 12, the spring mechanism 32 will restore its elasticity and then push the roller surface cleaning mechanism 31 forward along the Y direction, so that the roller surface cleaning mechanism 31 can clean the roller surface to be cleaned. When the top surface sliding portion 22 slides back, the guide portion 33 will move from the recessed position abutting against the axial cam 12 to the raised position, thereby driving the roller surface cleaning mechanism 31 to retract and compress the spring mechanism 32 again. Such a cycle can realize the cleaning of the roller surface to be cleaned. In this embodiment, the axial cam 12 and the guide portion 33 do not generate static electricity and sparks, and can achieve a preset running trajectory, meeting the design requirements that the roller surface cleaning mechanism 31 is disengaged from the roller surface to be cleaned in the initial position and fits the roller surface to be cleaned in the working position. Preferably, the axial cam 12 is made of high-strength engineering plastic material.

[0034] Please continue to refer to Figure 1-Figure 4 As shown, in this embodiment, it is also necessary to explain that the roller surface cleaning mechanism 31 includes a roller surface mounting frame 311, a material discharge roller 312, a pressure strip 313 and a material receiving roller 314. The bottom of the roller surface mounting frame 311 is slidably mounted on the top surface sliding portion 22, and the guide portion 33 is mounted at the bottom position of the roller surface mounting frame 311 and passes through the top surface sliding portion 22 and then abuts against the axial cam 12. The end of the spring mechanism 32 is connected to the side position of the bottom of the roller surface mounting frame 311, so that the compression or recovery of the spring mechanism 32 is achieved by pushing out or retracting the roller surface mounting frame 311.

[0035] The unloading roller 312, the pressure strip 313 and the collecting roller 314 are all mounted on the roller surface mounting frame 311. It can be understood that the pressure strip 313 is mounted on the side of the roller surface mounting frame 311 facing the roller surface to be cleaned, and the unloading roller 312 and the collecting roller 314 realize the reeling and unloading operation, and the wiping cloth is wound around the unloading roller 312, the pressure strip 313 and the collecting roller 314 in sequence and continuously, that is, the wiping cloth on the unloading roller 312 is led out, bypasses the pressure strip 313 and is then wound around the collecting roller 314. Then, through the cooperation of the unloading roller 312 and the collecting roller 314, the wiping cloth on the pressure strip 313 can be replaced, and then when the roller surface cleaning mechanism 31 is pushed out, the wiping cloth on the pressure strip 313 is adhered to the roller surface to be cleaned, thereby achieving cleaning during the reciprocating sliding process. The pressure strip 313 plays a role in shaping the wiping cloth, and can fit the roller surface to be cleaned, thereby facilitating the cleaning operation on the roller surface to be cleaned. Preferably, the wiping cloth is made of non-woven fabric.

[0036] Reference Figure 1 , Figure 2 As shown, in this embodiment, it is also necessary to explain that the grooves 10 at both ends of the guide rail 1 are respectively provided with adjustable limiters 5, and the roller surface wiping part 3 stops sliding when following the sliding part 2 and sliding and touching the adjustable limiter 5, so the sliding stroke of the roller surface wiping part 3 can be controlled by the adjustable limiter 5. The side of the guide rail 1 is provided with an inductive proximity switch, and the inductive proximity switch can fix its position according to the on-site reversing or stopping requirements; the roller surface wiping part 3 is provided with a sensing part used in conjunction with the inductive proximity switch, and the roller surface wiping part 3 stops and slides back when following the sliding part 2 and sliding until the sensing part is aligned with the position of the inductive proximity switch, and then the stop timing of the roller surface wiping part 3 can be accurately controlled by the use of the inductive proximity switch. It can be understood that when the inductive proximity switch detects the roller surface wiping part 3, the machine stops and reverses, and the roller surface wiping part 3 returns and stops when it returns to the starting position. If multiple reciprocating cleaning is required, it can be controlled by electrical control.

[0037] In this embodiment, in actual use, the installation positions of the adjustable limit 5 and the inductive proximity switch can be determined according to the size of the on-site production line and the cleaning range.

[0038] Please refer to Figure 1-Figure 3As shown, in this embodiment, it is also necessary to explain that the power unit 4 includes a stepless wire rope winch 41 and a stepless wire rope 42. The stepless wire rope winch 41 controls and drives the sliding part 2 to slide back and forth on the guide rail part 1 through the stepless wire rope 42. The stepless wire rope winch 41 is a relatively mature technical solution in the prior art and is not described in detail in this embodiment. For example, the stepless wire rope winch 41 is arranged on one side of the tank body 10, and the stepless wire rope 42 is connected to the stepless wire rope winch 41 and extends along the length direction of the guide rail part 1, and is locked with the side of the sliding part 2. Then, the stepless wire rope winch 41 can be used to control the stepless wire rope 42 to drive the sliding part 2 to slide back and forth along the guide rail part 1.

[0039] The implementation principle of this embodiment is as follows: before the roller surface online cleaning device is started, the adjustable limit 5 and the inductive proximity switch are fixed according to the size of the production line, and the non-woven fabric coil is wound around the unwinding roller 312, the pressure strip 313 and the receiving roller 314, and then the stepless wire rope winch 41 is started, and the stepless wire rope winch 41 rotates forward to drive the stepless wire rope 42 to move, and the stepless wire rope 42 drives the sliding part 2 to move linearly along the guide rail part 1. During the movement, the roller surface cleaning mechanism 31 extends and makes the non-woven fabric contact with the roller surface to be cleaned, and the roller surface wiping part 3 moves along the guide rail part 1 to clean the roller surface to be cleaned, and stops when it touches the adjustable limit 5. When the inductive proximity switch detects the roller surface wiping part 3, it stops and reverses, and the roller surface wiping part 3 returns and stops when it returns to the starting position. If multiple reciprocating cleanings are required, electrical control can be used;

[0040] In this embodiment, each component is independently manufactured and easy to install and disassemble. When the roller surface needs to be cleaned, the roller surface online cleaning device is directly started, and the cleaning can be automatically completed within the specified time. The operation is stable and no personnel are required to enter. Compared with manual cleaning, the operation is simple, the efficiency is high, the cleaning effect is good, and the safety is high.

[0041] It should be understood that the above specific embodiments of the present application are only used to illustrate or explain the principles of the present application, and do not constitute a limitation to the present application. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present application should be included in the protection scope of the present application.
