Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, and specifically to a cleaning mechanism for a coating machine. Background Technology

[0002] Coating machines are mainly used for surface coating processes of films, paper, etc.

[0003] A search revealed a patent document with authorization announcement number CN219992058U, which discloses a paper coating machine. The coating machine includes: a coating machine body, two fixed blocks, a drive assembly, two chutes, and an adjustment assembly. The two fixed blocks are fixedly connected to one side of the coating machine body, and a base plate is fixedly connected between the two fixed blocks. Two dust-removing rollers are rotatably connected between the two fixed blocks. The drive assembly is located within one of the fixed blocks and is used to drive the two dust-removing rollers to rotate in opposite directions. The two chutes are respectively opened on one side of the two fixed blocks, and an extrusion plate is slidably connected between the two chutes. The adjustment assembly is located within one of the fixed blocks and is used to drive the extrusion plate to move up and down.

[0004] The above-mentioned method of cleaning paper by adding two dust-removing rollers to the coating machine body has several drawbacks. Since the positions of the two dust-removing rollers are fixed, a significant amount of dust and other foreign matter will adhere to them during prolonged use. If this dust and foreign matter are not cleaned, they will accumulate and form a large volume, potentially scratching the paper that follows. Cleaning the dust-removing rollers requires a period of downtime by skilled workers, and the cleaning time varies depending on the experience of the workers, leading to reduced production efficiency.

[0005] To address these issues, we propose a cleaning mechanism for coating machines. Utility Model Content

[0006] The purpose of this invention is to solve the problems in the prior art by proposing a cleaning mechanism for a coating machine. This cleaning mechanism is equipped with cleaning rollers that can roll and abut against the paper to clean dust and other foreign objects on the paper surface. Multiple cleaning rollers are provided, and they can be quickly switched between each other. That is, continuous cleaning of paper can be achieved without stopping the machine. This makes the cleaning mechanism convenient to use and highly efficient.

[0007] To solve the above problems, this utility model provides the following technical solution:

[0008] A cleaning mechanism for a coating machine includes a main roller for conveying paper to the coating machine and a cleaning assembly. The cleaning assembly includes a power shaft rotatably disposed above the main roller and a cleaning roller rotatably disposed on the outer circumference of the power shaft. The cleaning roller can rotate with the power shaft to be above the main roller and make rolling surface contact with the paper on the main roller, and the rotation axis of the cleaning roller is parallel to the rotation axis of the main roller. The cleaning roller is configured as a plurality of rollers and arranged in a circumferential array on the power shaft.

[0009] As a further embodiment of this utility model: the cleaning assembly also includes an adapter, which includes two telescopic rods disposed on the outer circumference of the power shaft and distributed along the axial length of the power shaft. The two ends of the cleaning roller are respectively rotatably disposed on the piston rods of the two telescopic rods, so that the two telescopic rods and the cleaning roller together form a gantry-type layout.

[0010] As a further embodiment of this utility model: the cleaning component also includes a locking member, which includes a pin and a paddle. The pin is fixedly mounted on the piston cylinder of the telescopic rod, and the paddle is rotatably mounted on a support bracket for mounting the main roller, and the paddle has a groove for locking the pin.

[0011] As a further embodiment of this utility model: the telescopic rod is provided with an elastic element, which is used to make the piston rod have a tendency to move closer to the main roller.

[0012] As a further embodiment of this utility model: the elastic element is a spring, which is sleeved on the telescopic rod, and its two ends are respectively connected to the piston cylinder and piston rod of the telescopic rod.

[0013] As a further embodiment of this invention, the cleaning mechanism also includes a hanger for mounting the power shaft, the rotation axis of which is parallel to the rotation axis of the main roller.

[0014] As a further aspect of this invention, the cleaning mechanism also includes a secondary roller for pressing the paper.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. With multiple cleaning rollers, the rollers can be sequentially moved to the top of the main roller to make rolling contact with the paper. The rapid switching between the multiple cleaning rollers allows for continuous cleaning of the paper without stopping the machine, shortening the changeover time and ensuring paper production efficiency.

[0017] 2. By setting up the elastic element, when the cleaning roller at the bottom touches the paper on the main roller, it will not only be subject to the combined gravity of the piston rod and the cleaning roller, but also to the elastic force of the elastic element, so that the cleaning roller can contact the paper on the main roller more stably and adapt to paper with different walking speeds.

[0018] 3. By setting the locking mechanism, when the bottom cleaning roller comes into contact with the paper on the main roller, it can drive the lever to rotate, so that the groove on the lever engages with the pin. Relying on the locking between the pin and the lever, the position of the cleaning roller is limited and fixed, further ensuring the stability of the cleaning roller position.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0027] The coating machine b involved in this embodiment is a conventional setup in the prior art, while the cleaning mechanism proposed in this embodiment is used to pre-clean the paper a, and then the cleaned paper a is transported to the coating machine b for processing via a conveying device.

[0028] like Figures 1-5 As shown, a cleaning mechanism for a coating machine is generally installed on the side of the coating machine b. The cleaning mechanism includes a main roller 1, a secondary roller 11, and a cleaning component. The main roller 1 is used to transport paper a to the coating machine b. The secondary roller 11 is used to assist in pressing the paper a during the conveying process. During the conveying process, the cleaning component is used to clean the paper a supported on the main roller 1.

[0029] Specifically, the cleaning assembly includes a power shaft 2 rotatably mounted above the main roller 1 and a cleaning roller 3 rotatably mounted on the outer circumference of the power shaft 2. The cleaning mechanism also includes a hanger 10, on which the power shaft 2 is rotatably mounted, and the axis of rotation of the power shaft 2 is parallel to the axis of rotation of the main roller 1. The cleaning roller 3 can rotate with the power shaft 2 to above the main roller 1 and make rolling surface contact with the paper a on the main roller 1, and the axis of rotation of the cleaning roller 3 is parallel to the axis of rotation of the main roller 1. This state can be achieved by... Figure 1 To illustrate, during the process of paper a being driven by the main roller 1, the cleaning roller 3 makes rolling surface contact with the upper surface of paper a, and the cleaning roller 3 can absorb and remove dust and other foreign objects on paper a.

[0030] like Figure 2 and Figure 5 As shown, for the above-mentioned installation design of the cleaning roller 3 on the power shaft 2, the cleaning assembly can also include an adapter. The adapter includes two telescopic rods 4 disposed on the outer circumference of the power shaft 2, and the line connecting the two telescopic rods 4 is parallel to the length direction of the power shaft 2. The telescopic rod 4 consists of a piston cylinder and a piston rod. The two ends of the cleaning roller 3 are respectively rotatably disposed on the piston rods of the two telescopic rods 4, so that the two telescopic rods 4 and the cleaning roller together form a gantry-type layout. Figure 1 As shown, the cleaning roller 3 at the bottom is located directly above the main roller 1. At this time, the cleaning roller 3 is rolled and comes into contact with the paper a on the main roller 1 by the piston rod and the gravity of the cleaning roller 3 to perform the cleaning work.

[0031] like Figures 3-4 As shown, in order to ensure Figure 1 The cleaning roller 3, operating in a stable position, can be equipped with a cleaning assembly that includes a locking mechanism. The locking mechanism comprises a pin 5 and a lever 6. The pin 5 is fixedly mounted on the piston cylinder of the telescopic rod 4. The lever 6 is rotatably mounted on the support bracket 7 for mounting the main roller 1, and the lever 6 has a groove 8 for engaging the pin 5. The state of the paper a on the main roller 1 after the telescopic rod 4 and cleaning roller 3 are rotated can be determined by… Figure 4To illustrate, at this time, the cleaning roller 3 is in rolling contact with the paper a, and then the paddle 6 can be driven to rotate until the groove 8 on the paddle 6 is engaged with the pin 5. At this time, the piston cylinder of the telescopic rod 4 will be locked on the support bracket 7, ensuring the stable operation of the cleaning roller 3.

[0032] like Figures 2-5 As shown, under the aforementioned situation where the cleaning roller 3 is pressed against the paper a solely by the combined gravity of the piston rod and the cleaning roller 3, in order to better ensure proper contact between the cleaning roller 3 and the paper a, an elastic element 9 can be provided on the telescopic rod 4. The elastic element 9 is used to give the piston rod a tendency to move closer to the main roller 1, that is, in Figure 1 In the state shown, the elastic element 9 is in a compressed state. The cleaning roller 3 is not only subject to its own gravity and the gravity of the piston rod, but also to the downward reset action of the elastic element 9, which makes the contact between the cleaning roller 3 and the paper a tight. It can adapt to different paper a walking speeds and has a wide range of applications.

[0033] like Figures 1-2 As shown, to avoid the time-consuming process of replacing the cleaning roller 3 after prolonged use, this embodiment uses multiple cleaning rollers 3, arranged in a circumferential array on the power shaft 2. Simultaneously, multiple adapters and elastic elements 9 are also provided, their number matching the number of cleaning rollers 3. This configuration can be achieved by... Figure 2 To represent. In Figure 1 In the indicated state, when the cleaning roller 3 located at the bottom needs to be replaced after a period of use, the operator drives the power shaft 2 to rotate clockwise, causing the cleaning roller 3 located at the bottom to be moved to the top, and the cleaning roller 3 located at the top to be moved to the bottom, making rolling contact with the paper a on the main roller 1. During this process, the cleaning roller 3, moving from top to bottom, is pressed by the main roller 1, causing the telescopic rod 4 to retract, and the elastic element 9 is compressed. The compressed elastic element 9 can apply a downward elastic force to the cleaning roller 3 located at the bottom. Subsequently, the operator can clean the cleaning roller 3 that has been switched to the top position, removing dust and other foreign matter, ensuring that it can be directly reused. This utility model, through this method of quickly switching the cleaning roller 3, can achieve continuous cleaning of the paper a without stopping the machine, without delaying production time and ensuring production efficiency.

[0034] It should be noted that the elastic element 9 used to apply downward elastic force to the cleaning roller 3 can be a spring or a rubber strip, as long as it can achieve the corresponding elastic function; when the elastic element 9 is set as a spring, the spring is sleeved on the telescopic rod 4, and its two ends are respectively connected to the piston cylinder and piston rod of the telescopic rod 4.

[0035] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
