[0031] The following is an explanation of the implementation of the present invention by specific specific embodiments. Those skilled in the art can easily understand other advantages and functions of the present invention from the contents disclosed in this specification. Although the description of the present invention will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this utility model are limited to this implementation. On the contrary, the purpose of introducing the utility model in conjunction with the implementation is to cover other options or modifications that may be extended based on the claims of the present invention. In order to provide a deep understanding of the present invention, the following description will include many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description. It should be noted that, in the absence of conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0032] It should be noted that in this specification, similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0033] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0034] In the description of this embodiment, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0035] In the current production process, the roller of the silk drying machine often moves up and down during operation, which affects the normal operation of the silk drying machine and is prone to malfunction.

[0036] In order to solve the above technical problems, the inventors have found that the main reason why the current silk drying machine drum 8 is prone to up and down movement is that when the silk drying machine is operating normally, the central axis of the drum 8 (such as Figure 1a L1 in FIG. 1 ) and the central axis of the supporting wheel 9 (as shown in FIG. Figure 1a As shown by line L2 in Figure 1a When a large amount of smoke and dust adhere to the support roller 9 to form dirt, the circumferential surface of the support roller 9 will be uneven, causing the roller 8 supported by the support roller 9 to tilt, and the central axis of the roller 8 is no longer parallel to the central axis of the support roller 9, as shown in FIG. Figure 1b As shown, the drum 8 is caused to deflect during rotation, thereby causing the drum 8 to move.

[0037] The utility model provides a cleaning device, which can effectively remove the dirt on the surface of the supporting roller 9, keep the circumferential surface of the supporting roller 9 flat, avoid the roller 8 from being skewed, thereby avoiding the roller 8 from moving, and ensuring normal production.

[0038] In order to make the technical solution and advantages of the present invention more clear, the implementation methods of the present invention are described in further detail below.

[0039] refer to Figures 2 to 5 The embodiment of the utility model provides a cleaning device, including a bracket 1, a scraper 2, a mounting assembly 3 and an elastic component 4, wherein the mounting assembly 3 is arranged on the bracket 1. The scraper 2 is arranged on the mounting assembly 3, and a cleaning surface 21 is provided on the scraper 2, and the cleaning surface 21 contacts the outer circumferential surface of the supporting roller 9, such as Figure 4 The elastic component 4 is used to apply a force to the scraper 2 toward the circumferential surface of the supporting roller 9 (as shown in FIG. Figure 4 As shown in the force F in the figure), the cleaning surface 21 contacts the outer circumferential surface of the supporting roller 9.

[0040] The utility model provides a scraper 2 with a cleaning surface 21, fixes the scraper 2 on the bracket 1 through the mounting assembly 3, and the elastic component 4 applies a force to the scraper 2 toward the circumferential surface of the supporting roller 9, so that the cleaning surface 21 on the scraper 2 contacts the outer circumferential surface of the supporting roller 9. When the supporting roller 9 is rotating, the cleaning surface 21 can clean the outer circumferential surface of the supporting roller 9 to remove the tobacco powder and dust attached to the supporting roller 9 of the silk drying machine, thereby avoiding the problem that the circumferential surface of the supporting roller 9 is uneven due to scale accumulation on the surface of the supporting roller 9, causing the drum 8 to be skewed, and then causing the drum 8 to move.

[0041] refer to Figure 6 In some embodiments, the scraper 2 can also be fixed to the bracket 1 by providing a locking member 33 so that the cleaning surface 21 contacts the outer circumference of the support roller 9 to clean the support roller 9. However, after long-term use, the scraper 2 is worn, and the cleaning surface 21 cannot be in close contact with the outer circumference of the support roller 9, making it difficult to continue cleaning the support roller 9.

[0042] In order to solve the above technical problems, the utility model sets an elastic component 4. When the scraper 2 is worn due to long-term use, resulting in the cleaning surface 21 being unable to make close contact with the outer circumferential surface of the support roller 9, the elastic component 4 can push the scraper 2 to move toward the circumferential surface of the support roller 9, so that the cleaning surface 21 always keeps in contact with the outer circumferential surface of the support roller 9, thereby avoiding the problem that the cleaning surface 21 cannot make close contact with the support roller 9 due to the wear of the scraper 2, making it difficult to clean the support roller 9.

[0043] Optionally, refer to Figure 2 and Figure 5 The mounting assembly 3 includes a fixing seat 31, on which there is a Figure 5 The scraper 2 passes through the limiting groove 32 of the fixing seat 31 (shown in the X direction in FIG). The fixing seat 31 and the limiting groove 32 are provided to facilitate installation and removal of the scraper 2.

[0044] Optionally, refer to Figures 2 to 4 , and also includes an adjustment mechanism for adjusting the elastic force of the elastic component 4, the adjustment mechanism is arranged on the bracket 1, including a sliding member 5, a support 10 and an adjustment member 6, the sliding member 5 is slidably connected to the bracket 1, exemplarily, refer to Figure 3The bracket 1 is provided with a slide groove 7 extending in a first direction, and a slide seat 51 is provided at the bottom of the sliding member 5. The slide seat 51 is slidably arranged in the slide groove 7. One end of the elastic component 4 contacts the side of the sliding member 5, and the other end of the elastic component 4 contacts the scraper 2. The sliding member 5 can slide in the first direction, and the first direction is parallel to the extension direction of the elastic component 4. The support 10 is provided on the bracket 1. The adjusting member 6 is provided on the support 10, and the adjusting member 6 is used to drive the sliding member 5 to slide in the first direction. For example, the adjusting member 6 is a bolt, and the support 10 is provided with a mounting hole 11 penetrating the support 10 in the first direction. The adjusting member 6 is inserted into the mounting hole 11. The mounting hole 11 can limit the movement of the adjusting member 6 in the first direction, but does not limit the rotation of the adjusting member 6 in the mounting hole 11. The sliding member 5 is provided with a threaded hole penetrating the sliding member 5 in the first direction. The adjusting member 6 is inserted into the threaded hole and is threadedly connected with the threaded hole. The elastic component 4 is a spring.

[0045] The utility model is provided with an adjustment mechanism, and the adjustment member 6 can be rotated to make the sliding member 5 slide along the slide groove 7 toward the supporting roller 9 under the action of the threaded transmission, so as to compress the elastic member 4, thereby increasing the force of the elastic member 4 on the scraper 2, so that the cleaning surface 21 is kept in close contact with the outer circumferential surface of the supporting roller 9, thereby avoiding the problem that the cleaning surface 21 cannot be in close contact with the supporting roller 9 due to the elastic force of the elastic member 4 being too small.

[0046] Optionally, the scraper 2 is made of polytetrafluoroethylene, which has good wear resistance, can increase the service life of the scraper 2, reduce the replacement frequency of the scraper 2, and thus save costs.

[0047] Optionally, the fixing seat 31 is made of stainless steel. Stainless steel has good corrosion resistance, so that the fixing seat 31 has a long service life.
