Description

Technical Field

[0001] This application relates to the technical field of cleaning devices, and in particular to a cooling drum cleaning device. Background Technology

[0002] When the tire tread is being wound, the rubber strips extruded by the extruder are first wound around the outer periphery of the cooling drum. During the conveying process of the rubber strips, they are cooled down by the rotating cooling drum so that the rubber strips reach the temperature required for the winding process. Then, the winding machine winds and fixes them onto the tire blank.

[0003] In actual operation, residual rubber and dust and other debris easily adhere to the surface of the cooling drum. If it is not cleaned in time, it will seriously affect the molding quality of the subsequent rubber strips, resulting in impurities in the tire tread of the tires wound by the subsequent winding machine. Therefore, the cooling drum needs to be cleaned regularly. At present, the cooling drum is mostly cleaned manually, specifically by the operator using a rag and cleaning agent.

[0004] Regarding the aforementioned technologies, on the one hand, manual cleaning is inefficient, and the cooling drum is prone to rotation during the cleaning process, making the overall cleaning difficult. On the other hand, some of the adhesive residue remaining on the surface of the cooling drum has strong adhesion, requiring scraping with a scraper during the cleaning process, which is inconvenient and can easily damage the surface of the cooling drum. Therefore, there is room for improvement. Summary of the Invention

[0005] To facilitate the cleaning of residual adhesive and dust impurities on the outer periphery of the cooling drum, this application provides a cooling drum cleaning device.

[0006] This application provides a cooling drum cleaning device, which adopts the following technical solution:

[0007] A cooling drum cleaning device includes a first cleaning mechanism and a second cleaning mechanism;

[0008] Both the first cleaning mechanism and the second cleaning mechanism are supported at the bottom of the cooling drum and are distributed sequentially along the rotation path of the cooling drum;

[0009] The first cleaning mechanism includes a first frame, on which a first support and a first driving member are mounted. A scraper is provided on the first support, and the first driving member is used to drive the first support to move the scraper toward or away from the cooling drum.

[0010] The second cleaning mechanism includes a second frame, on which a second support and a second driving member are provided; a cloth clamping plate is provided on the second support, and a cleaning protrusion is provided on the upper surface of the cloth clamping plate. A cleaning cloth is clamped on both sides of the cloth clamping plate by clamping members, and the cleaning cloth covers the cleaning protrusion; the second driving member is used to drive the second support to move the cloth clamping plate closer to or away from the cooling drum.

[0011] By adopting the above technical solution, when cleaning the cooling drum, the first driving component and the second driving component respectively drive the scraper and the cleaning cloth on the clamping plate to come into contact with the outer periphery of the cooling drum. During the rotation of the cooling drum, the scraper first scrapes off the larger residual adhesive material on the cooling drum, and then the cleaning cloth further cleans the remaining adhesive material and dust impurities on the cooling drum, realizing automatic cleaning of the cooling drum, effectively reducing the cleaning difficulty of the cooling drum, and effectively improving the overall cleaning efficiency of the cooling drum compared with traditional cleaning methods.

[0012] Preferably, the second frame is provided with connecting blocks at both ends, the connecting blocks are connected to the support frame of the cooling drum, the connecting blocks are provided with a plurality of second connecting elongated holes, the second connecting elongated holes are horizontally arranged, and second limiting bolts are threaded through the second connecting elongated holes and the second limiting bolts are threaded to the second frame.

[0013] By adopting the above technical solution, the second cleaning mechanism is prone to horizontal deviation from the cooling drum axis due to the manufacturing error of the support frame and the installation error of the cooling drum. By cooperating with the second connecting elongated hole on the connecting block and the second limiting bolt, the position of the second frame in the horizontal direction can be finely adjusted when installing the second cleaning mechanism, so that the second cleaning mechanism can be better kept parallel to the cooling drum axis in the horizontal direction, which makes it easier for the cleaning cloth on the second cleaning mechanism to better adhere to the surface of the cooling drum.

[0014] Preferably, the second driving component includes a second cylinder vertically supported on the second frame, the piston rod of the second cylinder being hinged to the second support, and the hinge axis of the second cylinder piston rod being perpendicular to the axis of the cooling drum; a second guide rod is provided at both ends of the second frame, the end of the second guide rod being hinged to the second support, and the hinge axes of the hinge ends of the second cylinder piston rod and the second guide rod being parallel.

[0015] By adopting the above technical solution, the second cylinder piston rod extends and retracts to drive the second support to move relative to the cooling drum. During the movement, the second guide rods at both ends of the second support can guide and limit the second support, which helps to ensure that the second support drives the clamping plate to move smoothly closer to or away from the cooling drum. By making both the second cylinder piston rod and the second guide rod hinged to the second support, when there is a vertical offset between the cooling drum axis and the second cleaning mechanism, the second support can drive the clamping plate to swing slightly, so that the cleaning cloth on the clamping plate can better abut against the cooling drum, which facilitates the subsequent cleaning of residual adhesive and dust on the cooling drum by the cleaning cloth abutting against the cooling drum.

[0016] Preferably, the upper surface of the cleaning protrusion is recessed with an arc-shaped surface, which is adapted to the outer contour of the cooling drum, and the cleaning cloth is attached to the arc-shaped surface.

[0017] By adopting the above technical solution, and by setting an arc-shaped surface on the cleaning protrusion that matches the outer contour of the cooling drum, it is beneficial to increase the contact area between the cleaning cloth and the cooling drum, so that the cleaning cloth can wipe the surface of the cooling drum more thoroughly, which facilitates further improvement of the cleaning effect of the cooling drum.

[0018] Preferably, a support shaft is connected parallel to the bottom of the scraper, and the two ends of the support shaft are respectively rotatably inserted through the two ends of the first support; a connecting arm is vertically connected to both ends of the support shaft, and an elastic element is provided at the end of the first support corresponding to the connecting arm. The elastic element is connected to the connecting arm, and the elastic element is used to drive the connecting arm to drive the scraper to swing toward the cooling drum through the support shaft so as to abut against the cooling drum.

[0019] By adopting the above technical solution, when the cooling drum vibrates during the cleaning process, the scraper can move adaptively accordingly, ensuring that the scraper abuts against the surface of the cooling drum while limiting the possibility of rigid collision between the scraper and the cooling drum that could cause damage to both. At the same time, when the scraper wears down, the connecting arm can be driven by the elastic element to rotate the support shaft, so that the support shaft drives the scraper to swing towards the cooling drum, ensuring that the scraper blade can always abut against the cooling drum and ensuring the scraping effect of the scraper on the cooling drum.

[0020] Preferably, the top of the second support is connected to a connecting plate, and a plurality of connecting bolts are threaded through one side of the connecting plate and the connecting bolts are threaded to the fabric clamping plate; a positioning groove is provided at the bottom of the fabric clamping plate, and the connecting plate is embedded in the positioning groove.

[0021] By adopting the above technical solution, the second support and the cloth clamping plate are connected by connecting bolts, achieving a stable connection between the two. When replacing the cleaning cloth, the cloth clamping plate can be removed from the second support, eliminating the need to replace the cleaning cloth in the limited space below the cooling drum. With the positioning groove at the bottom of the cloth clamping plate, when installing the connecting bolts, the connecting plate at the top of the second support can be embedded into the positioning groove to achieve quick positioning of the second support and the cloth clamping plate, facilitating the subsequent installation of the connecting bolts.

[0022] Preferably, the clamping member includes a clamping strip, and the cleaning cloth is located between the clamping strip and the clamping plate; the clamping strip is connected to a plurality of clamping blocks, and the end of the clamping block away from the clamping strip is bent to form a connecting end, the connecting end extends to the bottom of the clamping plate, and each connecting end is threaded with a fixing bolt, the end of the fixing bolt abutting against the bottom of the clamping plate so that the clamping strip presses the cleaning cloth.

[0023] By adopting the above technical solution, when installing the cleaning cloth, after laying the cleaning cloth on the clamping plate, the clamping strips are pressed against both sides of the clamping plate, and the fixing bolts at the clamping block connecting ends of the clamping strips are tightened, so that the ends of the fixing bolts press against the bottom of the clamping plate, thereby driving the clamping strips to press the cleaning cloth firmly onto the clamping plate, thus achieving a stable installation of the cleaning cloth on the clamping plate. When replacing the cleaning cloth, the fixing bolts are loosened to release the clamping strips from pressing the cleaning cloth, releasing the clamping limit on the cleaning cloth, and facilitating the installation and replacement of the clamping strips.

[0024] Preferably, the bottom of the first support is provided with an adhesive collection groove, which is located at the bottom of the support shaft and is used to collect the adhesive scraped off from the cooling drum by the scraper.

[0025] By adopting the above technical solution, the rubber and dust scraped off from the cooling drum by the scraper can fall into the rubber collection tank, so as to realize the centralized collection of rubber and dust impurities, which facilitates the subsequent treatment of rubber and dust impurities.

[0026] Preferably, the two ends of the scraper extend out of the two ends of the cooling drum, and the two ends of the scraper are respectively separated from the two ends of the first support; the scraper end is provided with a scraping component, the scraping component is formed with a snap-fit ​​groove, the snap-fit ​​groove is adapted to the contour of the scraper blade, and the scraping component is sleeved on the scraper blade through the snap-fit ​​groove.

[0027] By adopting the above technical solution, the adhesive material is inherently sticky and easily adheres to the scraper blade. With the scraper component, it can slide along the scraper blade to scrape off the adhesive material remaining on the scraper blade. The slot on the scraper component allows it to slide stably on the scraper blade while covering both sides of the scraper blade, which helps to clean the residual adhesive material on the scraper blade more thoroughly.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The first and second driving components are used to make the scraper and the cleaning cloth on the clamping plate come into contact with the outer periphery of the cooling drum. When the cooling drum rotates, the scraper can first scrape off larger residual adhesive materials, and then the cleaning cloth on the clamping plate can further remove residual dust and some adhesive materials, thereby realizing automatic cleaning of the cooling drum and effectively improving the cleaning efficiency of the cooling drum.

[0030] 2. By hinged the piston rod of the second cylinder and the second guide rod to the bottom of the second support, when the cooling drum axis is offset from the second cleaning mechanism in the vertical direction, the second support can drive the clamping plate to swing slightly so that the cleaning cloth on the clamping plate can better abut against the cooling drum, making it easier to clean residual dust and adhesive with the cleaning cloth later.

[0031] 3. With the elastic element at the end of the first support, when the cooling drum vibrates, the scraper can move accordingly through the elastic element, ensuring that the scraper abuts against the surface of the cooling drum while avoiding rigid collision between the scraper and the cooling drum; when the scraper wears, the elastic element can drive the connecting arm to rotate the support shaft, so that the support shaft drives the scraper to rotate toward the cooling drum, ensuring that the scraper blade is always in contact with the cooling drum.

[0042] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0043] Reference Figure 1 The bottom of the cooling drum 1 is provided with a support frame 11. Both ends of the cooling drum 1 are rotatably mounted on the support frame 11 through bearing seats. The support frame 11 is also provided with a rotary drive component for driving the cooling drum 1 to rotate.

[0044] This application discloses a cooling drum cleaning device, referring to... Figure 1 It includes a first cleaning mechanism 2 and a second cleaning mechanism 3, both of which are supported at the bottom of the cooling drum 1 and distributed sequentially along the rotation path of the cooling drum 1.

[0045] Reference Figure 1 and Figure 2 In this embodiment, the first cleaning mechanism 2 is used to scrape off large pieces of residual adhesive material from the outer periphery of the cooling drum 1. The first cleaning mechanism 2 includes a first frame 20, which is connected to a support frame 11 at the bottom of the cooling drum 1. The first frame 20 is supported by a first support 21 and a first driving member. The bottom of the first support 21 is horizontally slidably connected to the first frame 20 via a slider rail structure. A scraper 22 is supported on the first support 21, which is positioned opposite to the cooling drum 1, and the length direction of the scraper 22 is parallel to the axial direction of the cooling drum 1. The first driving member is drivenly connected to the first support 21 and is used to drive the first support 21 to move the scraper 22 in a horizontal direction toward or away from the cooling drum 1.

[0046] When the first cleaning mechanism 2 cleans the residual adhesive on the outside of the cooling drum 1, the first driving component drives the first support 21 to swing the scraper 22 toward the cooling drum 1 until the blade of the scraper 22 comes into contact with the outer periphery of the cooling drum 1. Then, in conjunction with the rotation of the cooling drum 1, the large pieces of adhesive remaining on the outer periphery of the cooling drum 1 can be scraped off by the scraper 22.

[0047] Reference Figure 1 and Figure 3 The scraper 22 extends out from both ends of the cooling drum 1, allowing it to better cover the drum 1. A support shaft 221 is connected parallel to the bottom of the scraper 22, with bearings at both ends of the support shaft 221 rotatably passing through both ends of the first support 21. Connecting arms 223 are vertically connected to both ends of the support shaft 221. Elastic elements are provided at the ends of the first support 21 corresponding to the connecting arms 223, and these elements are connected to the corresponding connecting arms 223 to drive the connecting arms 223 to swing the scraper 22 towards the cooling drum 1 via the support shaft 221, thus abutting against the cooling drum 1.

[0048] The outer side of the first support 21 is connected to a protrusion 210. The axial direction of the protrusion 210 is parallel to the axial direction of the support shaft 221. A drive rod 211 is vertically connected to the protrusion 210. The axial direction of the drive rod 211 is perpendicular to the axial direction of the support shaft 221. The drive rod 211 is inclined upward towards the axial direction of the cooling drum 1. The connecting arm 223 has a movable elongated hole for the drive rod 211 to move. The drive rod 211 passes through the movable elongated hole. The end of the drive rod 211 is connected to a limit nut 212. The elastic element includes a drive spring 213 coaxially sleeved on the drive rod 211. The two ends of the drive spring 213 abut against the drive rod 211 and the connecting arm 223 respectively. When the drive spring 213 is in the initial state, the blade of the scraper 22 extends inclined away from the cooling drum 1.

[0049] By using the elastic element, during the cleaning and scraping process of the cooling drum 1 by the scraper 22, when the cooling drum 1 vibrates during rotation, the scraper 22 can be displaced accordingly. This ensures that the scraper 22 always abuts against the surface of the cooling drum 1 while limiting rigid collisions between the scraper 22 and the cooling drum 1. Furthermore, after the scraper 22 wears down due to prolonged use, the elastic element, in conjunction with the connecting arm 223 at the end of the support shaft 221, can drive the scraper 22 to swing towards the cooling drum 1, so that the blade of the scraper 22 always abuts against the surface of the cooling drum 1, thus achieving automatic compensation for the wear of the scraper 22.

[0050] The support shaft 221 has two limiting protrusions 222 corresponding to the scraper 22. A gap is left between the two limiting protrusions 222 to form a limiting groove. The bottom of the scraper 22 is embedded in the limiting groove. Several fastening bolts are provided between the two limiting protrusions 222. The fastening bolts pass through the two limiting protrusions 222 and the scraper 22. The fastening bolts are connected to fastening nuts, and the fastening nuts are abutted against the limiting protrusions 222. This achieves a stable connection between the scraper 22 and the support shaft 221, while facilitating the disassembly and replacement of the scraper 22 after it is damaged.

[0051] Reference Figure 1 and Figure 3 A material collection trough 214 is placed on the first support 21. The material collection trough 214 is located at the bottom of the support shaft 221 and the scraper 22. The projection of the material collection trough 214 on the horizontal plane covers the projection of the support shaft 221 and the scraper 22 on the horizontal plane. The material scraped off the cooling drum 1 by the scraper 22 can fall into the material collection trough 214, which is convenient for cleaning and centralized collection of the material.

[0052] Reference Figure 1 and Figure 3 The scraper 22 has gaps at both ends relative to the first support 21. A scraper component 220 is provided on the blade of the scraper 22, located at one end of the scraper 22. The scraper component 220 has a locking groove that matches the contour of the blade of the scraper 22, and the scraper component 220 is fitted onto the blade of the scraper 22 through the locking groove. Subsequently, the scraper 22 is used to clean the adhesive on the surface of the cooling drum 1. After the first drive component drives the scraper 22 to detach from the cooling drum 1, the scraper component 220 can be moved along the overall length of the scraper 22 to scrape off the residual adhesive adhering to the blade of the scraper 22 and push it into the adhesive collection groove 214, thereby cleaning the adhesive on the blade of the scraper 22 and limiting the residual adhesive from interfering with the subsequent cleaning of the cooling drum 1 by the scraper 22. By having the scraper 220 fitted onto the blade of the scraper 22 through the snap-fit ​​groove, the scraper 220 is securely installed on the scraper 22, while also allowing the scraper 220 to better cover the front and rear sides of the blade of the scraper 22, which helps the scraper 220 to more thoroughly clean and scrape away the residual adhesive material located on the blade of the scraper 22.

[0053] At least two first connecting elongated holes are provided at both ends of the first frame 20. The first connecting elongated holes are horizontally set. A first limiting bolt is inserted into each of the first connecting elongated holes, and the first limiting bolt is threaded onto the support frame 11. With the above settings, when installing the first cleaning mechanism 2, the overall position of the first frame 20 can be adjusted in the horizontal direction by using the first connecting elongated holes at both ends of the first frame 20 in conjunction with the first limiting bolts, so that the first cleaning mechanism 2 is kept parallel to the cooling drum 1 in the horizontal direction, which is beneficial for the scraper 22 on the first cleaning mechanism 2 to better abut against the surface of the cooling drum 1.

[0054] Reference Figure 1 and Figure 2 The first driving component includes a first cylinder 23, which is mounted on the first frame 20 and faces the first support 21. The piston rod end of the first cylinder 23 is connected to the first support 21. Subsequently, by driving the piston rod to extend or retract through the first cylinder 23, the first support 21 can be moved closer to or further away from the cooling drum 1. First guide rods 25 are passed through both ends of the first frame 20 via first linear bearings 24. The first guide rods 25 are connected to the first support 21. During the subsequent sliding process of the first support 21, the first guide rods 25 can guide and limit its movement.

[0055] Reference Figure 1 and Figure 4 In this embodiment, the second cleaning mechanism 3 is used to further clean the residual adhesive and dust on the outer periphery of the cooling drum 1. The second cleaning mechanism 3 includes a second frame 30, which is connected to the support frame 11 of the cooling drum 1. A second support 31 and a second driving member are provided on the second frame 30. A cloth clamping plate 32 is supported on the second support 31. The two ends of the cloth clamping plate 32 extend out of the two ends of the cooling drum 1, and a cleaning protrusion 321 protrudes from the side of the cloth clamping plate 32 facing the cooling drum 1. The cleaning protrusion 321 is positioned facing the cooling drum 1. A cleaning cloth 33 is clamped on both sides of the cloth clamping plate 32 by clamping members. The cleaning cloth 33 covers the cleaning protrusion 321. The second driving member is used to drive the second support 31 to move in a vertical direction, moving the cloth clamping plate 32 closer to or away from the cooling drum 1.

[0056] When the cooling drum 1 is cleaned by the second cleaning mechanism 3, the second drive unit drives the second support 31 to move the clamping plate 32 upward until the cleaning cloth 33 on the clamping plate 32 comes into contact with the outer periphery of the cooling drum 1. In conjunction with the subsequent rotation of the cooling drum 1, the residual adhesive dust on the outer periphery of the cooling drum 1 is cleaned and removed by the cleaning cloth 33.

[0057] Reference Figure 1 and Figure 5 The cleaning protrusion 321 has an arc-shaped surface facing the cooling drum 1. The arc-shaped surface is adapted to the outer contour of the cooling drum 1. The cleaning cloth 33 is attached to the arc-shaped surface. The arc-shaped surface increases the contact area between the cleaning cloth 33 and the cooling drum 1, making it easier for the cleaning cloth 33 to better remove the adhesive and dust remaining on the outer periphery of the cooling drum 1.

[0058] Reference Figure 5 and Figure 6The clamping component includes a clamping strip 322, with both ends of the clamping strip 322 extending to both ends of the clamping plate 32. The side of the cleaning cloth 33 is located between the clamping strip 322 and the clamping plate 32. Several clamping blocks 323 are arranged along the length of the clamping strip 322. The end of each clamping block 323 away from the clamping strip 322 bends downward and extends to a connecting end, which extends to the bottom of the clamping plate 32. A fixing bolt 324 is threaded vertically through the connecting end, and the fixing bolt 324 abuts against the bottom of the clamping plate 32 to drive the clamping strip 322 to cooperate with the clamping plate 32 for clamping and limiting. Both the clamping strip 322 and the clamping blocks 323 are positioned below the cleaning protrusion 321.

[0059] Reference Figure 5 and Figure 6 The second support 31 has a connecting plate 311 integrally formed on its top. The connecting plate 311 extends upward at an angle away from the first cleaning mechanism 2. Several connecting bolts 312 are evenly inserted along the length of the second support 31 on its inclined upper side. The connecting bolts 312 are all threaded to the bottom of the clamping plate 32 to connect and fix the second support 31 to the clamping plate 32. At the same time, when the cleaning cloth 33 needs to be replaced later, the clamping plate 32 can be removed from the bottom of the cooling drum 1 to facilitate the removal and replacement of the cleaning cloth 33 on the clamping plate 32. By positioning the connecting bolts 312 on the inclined upper side of the connecting plate 311, it is convenient to remove and install the connecting bolts 312.

[0060] Reference Figure 5 and Figure 6 The bottom of the fabric clamping plate 32 is provided with a positioning groove 320 corresponding to the connecting plate 311. The two ends of the fabric clamping plate 32 are connected with cover plates, which block the end opening of the positioning groove 320. The connecting plate 311 is embedded in the positioning groove 320. The positioning groove 320 and the connecting plate 311 cooperate to facilitate the rapid positioning of the fabric clamping plate 32, which is convenient for the subsequent disassembly and assembly of the connecting bolt 312. At the same time, the positioning groove 320 can cooperate with the connecting plate 311 to provide auxiliary limiting, which is beneficial to improve the stress condition of the connecting bolt 312.

[0061] In this embodiment, both the connecting bolt 312 and the fixing bolt 324 are wing bolts, which facilitates their rotation.

[0062] Reference Figure 1 and Figure 7The second driving component includes a second cylinder 34 vertically supported on the second frame 30. The top end of the piston rod of the second cylinder 34 is hinged to the second support 31. The hinge axis of the hinged end of the piston rod of the second cylinder 34 is perpendicular to the axis of the cooling drum 1. Second guide rods 36 are passed through both ends of the second frame 30 via second linear bearings 35. The top ends of the two second guide rods 36 are hinged to the second support 31, and the hinge axes of the hinged ends of the piston rod of the second cylinder 34 and the second guide rods 36 are parallel. The second cylinder 34 drives the second support 31 to move the fabric clamping plate 32 towards or away from the cooling drum 1. The two second guide rods 36 can guide and limit the movement of the second support 31, which is beneficial to the smooth movement of the second support 31. By hinged to the piston rod of the second cylinder 34 and the second guide rod 36, the bottom clamping plate 32 of the second support 31 can swing slightly during the process of contacting the cooling drum 1. This allows the cleaning cloth 33 on the clamping plate 32 to better fit the cooling drum 1, reducing the possibility of the actual axial direction of the cooling drum 1 being offset from the second cleaning mechanism 3 in the vertical direction due to manufacturing errors of the support frame 11 or installation errors of the cooling drum 1, which would affect the subsequent fit between the cleaning cloth 33 and the cooling drum 1.

[0063] Reference Figure 1 and Figure 7 Each of the second guide rods 36 has a limiting ring 361 fitted at its bottom end. The limiting ring 361 is fixed to the second guide rod 36 by bolts. When the cleaning cloth 33 is in contact with the outer periphery of the cooling drum 1, the limiting ring 361 is in contact with the bottom end of the second linear bearing 35. The limiting ring 361 limits the movement of the second support 31 and the cloth clamping plate 32, preventing the cooling drum 1 from being affected by excessive pressure between the cleaning cloth 33 and the cooling drum 1.

[0064] Reference Figure 1 and Figure 8 The second frame 30 has connecting blocks 301 at both ends, which are connected to the support frame 11 of the cooling drum 1. Each connecting block 301 has at least two second connecting elongated holes 302, which are horizontally positioned. A second limiting bolt passes through each second connecting elongated hole 302 and is threaded onto the second frame 30. By adjusting the position of the second limiting bolt within the second connecting elongated hole 302, the horizontal position of the second frame 30 can be finely adjusted, thereby adjusting the relative horizontal position of the second cleaning mechanism 3 and the cooling drum 1. This allows the cleaning cloth 33 on the second cleaning mechanism 3 to fit more closely against the outer periphery of the cooling drum 1, reducing the possibility of horizontal misalignment between the actual axial direction of the cooling drum 1 and the second cleaning mechanism 3 due to manufacturing errors in the support frame 11 or installation errors in the cooling drum 1, which could affect the subsequent fit between the cleaning cloth 33 and the cooling drum 1.

[0065] The implementation principle of this application embodiment is as follows: When cleaning the cooling drum 1, the first drive member drives the first support 21 to drive the blade of the scraper 22 to abut against the cooling drum 1, while the second drive member drives the cleaning cloth 33 on the clamping plate 32 to abut against the cooling drum 1. After the rotary drive member on the support frame 11 drives the cooling drum 1 to rotate, the scraper 22 is used to scrape off the larger pieces of adhesive residue remaining on the outer periphery of the cooling drum 1, and then the cleaning cloth 33 is used to further remove the small pieces of adhesive and dust impurities on the outer periphery of the cooling drum 1, thereby achieving effective removal of the cooling drum 1.

[0066] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
