Description

Technical Field

[0001] The utility model relates to the technical field of calendering rollers, in particular to a calendering roller with a self-cleaning structure. Background Art

[0002] A calender is a device that consists of two or more rollers arranged in a certain form and that presses and stretches glass or other materials into a certain thickness at a certain temperature. The calender roller is an important component of the calender. Existing calenders can be divided into two-roller, three-roller, four-roller and five-roller calenders, etc. according to the number of rollers. When the calender roller is in operation, it comes into contact with the molten glass raw materials, and its surface may inevitably be contaminated with impurities. After the calendering operation is completed, its surface needs to be cleaned and maintained, so a calender roller with a cleaning structure is needed.

[0003] According to a publicly disclosed calendering roller for glass processing with a cleaning structure (publication number: CN219637092U), in the above application, when the calendering roller is working normally, under the action of centrifugal force, the rocker arm will unfold and rest on the surface of the resistance rod, so that the first roller neck can drive the small disc to rotate. When the small disc rotates, the volute spring can be tightened, so that the volute spring is in a compressed state. When the calendering roller finishes working, the volute spring recovers and drives the long rod and the bristles to clean the surface of the calendering roller.

[0004] However, during the actual use of the above-mentioned equipment, due to the high operating temperature of the calender roller, the bristles used for cleaning the surface of the calender roller are easily damaged after being heated, and the trajectory of the calender roller surface swept by the bristles is relatively constant, resulting in poor cleaning effect. In view of this, we propose a calender roller with a self-cleaning structure. Utility Model Content

[0005] The utility model aims to provide a calendering roller with a self-cleaning structure to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a calendering roller with a self-cleaning structure, comprising a main roller, an end of the main roller is penetrated by a mounting plate, and the mounting plate is rotatably connected to the main roller, and a cleaning component is arranged on the side wall of the mounting plate, and the cleaning component comprises:

[0007] A driving gear, the end of the main roller is penetrated by a driving gear, and the driving gear is fixedly connected to the main roller, the inner wall of the mounting plate is penetrated by a mounting cylinder, and the mounting cylinder is rotatably connected to the mounting plate, the mounting cylinder is penetrated by a driven gear, and the driven gear is fixedly connected to the mounting cylinder, and the driven gear meshes with the driving gear to realize transmission;

[0008] A magnetic attraction plate, the inner wall of the mounting tube is slidably mounted with the magnetic attraction plate, and a spring is fixedly connected between the magnetic attraction plate and the inner wall of the bottom end of the mounting tube;

[0009] A shifting rod is fixedly mounted on the outer wall of the mounting plate close to the main roller, a cleaning roller is movably arranged on the inner wall of the mounting cylinder, and an arc-shaped plate is fixedly mounted on the arc-shaped outer wall of the cleaning roller.

[0010] Preferably, the inner wall of the mounting cylinder is provided with a socket whose diameter matches the outer diameter of the cleaning roller to facilitate the installation of the cleaning roller, the magnetic plate and the spring. A strip limit block is provided on the arc-shaped outer wall of the cleaning roller, and a limit groove matching the strip limit block is provided on the inner wall of the socket, so that the cleaning roller can only move in the horizontal direction on the inner wall of the mounting cylinder, and will not rotate relative to the mounting cylinder.

[0011] Preferably, a magnetic block having a magnetic property opposite to that of the magnetic attraction plate is provided at the end of the cleaning roller, so that a stable connection state can be maintained between the magnetic attraction plate and the cleaning roller.

[0012] Preferably, the side wall of the arc plate is provided with an arc surface, and the end of the lever away from the mounting plate is provided with a spherical surface, so as to avoid the lever interfering with the movement of the arc plate and causing it to get stuck.

[0013] Preferably, a sleeve is fixedly mounted on the arc-shaped outer wall of the cleaning roller, a rotating rod is movably connected to the inner wall of the sleeve, an elastic telescopic rod is fixedly connected between the bottom end of the rotating rod and the inner wall of the bottom end of the sleeve, a spiral groove is provided on the arc-shaped inner wall of the sleeve, a convex ball is fixedly mounted on the arc-shaped outer wall of the rotating rod, the convex ball is arranged inside the spiral groove, and an arc-shaped steel wire is fixedly mounted on the arc-shaped outer wall of the rotating rod.

[0014] Preferably, the arc-shaped steel wires are provided in three groups, and the three groups of arc-shaped steel wires are evenly distributed in a circular array on the arc-shaped outer wall of the rotating rod, and the top end of the rotating rod is provided as a spherical surface, so that when the main roller rotates, the rotating rod rotates and moves toward one side of the inner part of the sleeve, thereby driving the arc-shaped steel wires to rotate, so as to move the nearby steel wire bristles and sweep off the glass residues on their surface.

[0015] Compared with the prior art, the utility model provides a calendering roller with a self-cleaning structure, which has the following beneficial effects:

[0016] 1. The calendering roller with the self-cleaning structure is provided with a cleaning component. With the continuous rotation of the cleaning roller, the lever periodically squeezes and pushes the arc plate. With the cooperation of the magnetic plate and the spring, the cleaning roller performs a small reciprocating motion in the horizontal direction while keeping rotating, so as to continuously clean the outer surface of the main roller, thereby preventing impurities generated during the glass embossing operation from adhering to the arc outer wall of the main roller and affecting the subsequent normal calendering operation.

[0017] 2. When the main roller of the calendering roller with the self-cleaning structure rotates, the outer surface of the main roller slightly squeezes the top of the rotating rod. Under the transmission cooperation of the spiral slide groove and the convex ball, the rotating rod rotates and moves toward the inner side of the sleeve, thereby driving the arc-shaped steel wire to rotate, so as to move the nearby steel wire bristles and sweep off the glass residue on its surface, thereby ensuring the cleaning effect of the cleaning roller on the main roller while avoiding the residual glass slag from damaging the outer surface of the main roller.

DETAILED DESCRIPTION

[0022] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: a calendering roller with a self-cleaning structure, comprising a main roller 1, an end of the main roller 1 is penetrated by a mounting plate 2, and the mounting plate 2 is rotatably connected to the main roller 1, a cleaning component is arranged on the side wall of the mounting plate 2, and the cleaning component comprises a driving gear 3, a mounting cylinder 4, a driven gear 5, a magnetic plate 7, a spring 8, a lever 9, a cleaning roller 6 and an arc plate 10.

[0023] In one embodiment of the utility model, a driving gear 3 is passed through the end of the main roller 1, and the driving gear 3 is fixedly connected to the main roller 1, a mounting tube 4 is passed through the inner wall of the mounting plate 2, and the mounting tube 4 is rotatably connected to the mounting plate 2, a driven gear 5 is passed through the mounting tube 4, and the driven gear 5 is fixedly connected to the mounting tube 4, the driven gear 5 meshes with the driving gear 3 to realize transmission, a magnetic plate 7 is slidably installed on the inner wall of the mounting tube 4, a spring 8 is fixedly connected between the magnetic plate 7 and the inner wall of the bottom end of the mounting tube 4, a lever 9 is fixedly installed on the outer wall of the mounting plate 2 close to the main roller 1, a cleaning roller 6 is movably provided on the inner wall of the mounting tube 4, and an arc plate 10 is fixedly installed on the arc-shaped outer wall of the cleaning roller 6.

[0024] Furthermore, there are two groups of mounting plates 2, and the two groups of mounting plates 2 are mirror-imaged at the left and right ends of the main roller 1, thereby providing stable support and mounting effect for the main roller 1. At the same time, the driven gear 5 is arranged below the driving gear 3, and the inner wall of the mounting cylinder 4 is provided with a socket with a diameter matching the outer diameter of the cleaning roller 6, so as to facilitate the installation of the cleaning roller 6, the magnetic plate 7 and the spring 8. In addition, a strip-shaped limit block is arranged on the arc-shaped outer wall of the cleaning roller 6, and a limit slide groove matching the above-mentioned strip-shaped limit block is arranged on the inner wall of the socket, so that the cleaning roller 6 can only move in the horizontal direction on the inner wall of the mounting cylinder 4, and will not rotate relative to the mounting cylinder 4. Specifically, another group of limit slide blocks is arranged on the arc-shaped outer wall of the magnetic plate 7, and another group of limit slide blocks is arranged on the arc-shaped outer wall of the magnetic plate 7. The slider is also installed in the limiting slide groove to enable the magnetic plate 7 to move only in the horizontal direction along the limiting slide groove. In the initial state, the spring 8 is in a compressed state. Specifically, the spring 8 keeps pushing the magnetic plate 7 to squeeze the end of the cleaning roller 6, and the end of the cleaning roller 6 is provided with a magnetic block with opposite magnetic properties to the magnetic plate 7, so that the magnetic plate 7 and the cleaning roller 6 can maintain a stable connection state, thereby ensuring the stability of the cleaning roller 6 when moving. In addition, the arc-shaped outer surface of the cleaning roller 6 is provided with steel wire bristles to better clean the impurities on the arc-shaped outer surface of the main roller 1, and because the strength of the steel wire bristles themselves is relatively low, even if the steel wire bristles come into contact with the outer surface of the main roller 1, it will not cause excessive damage to the pattern opened on the arc-shaped outer wall of the main roller 1, thereby affecting the normal use of the main roller 1.

[0025] In addition, the center axis of the lever 9 and the cleaning roller 6 are arranged in the same plane, and the side wall of the arc plate 10 is provided with an arc surface, and at the same time, the end of the lever 9 away from the mounting plate 2 is arranged as a spherical surface to prevent the lever 9 from interfering with the movement of the arc plate 10 and causing it to get stuck. At the same time, the distance between the lever 9 and the center axis of the cleaning roller 6 is smaller than the distance between the arc-shaped outer wall of the arc plate 10 and the center axis of the cleaning roller 6, so that when the cleaning roller 6 rotates with the mounting cylinder 4, the end of the lever 9 will squeeze the arc plate 10 in the horizontal direction, thereby promoting The cleaning roller 6 is affected by the limiting slider and the limiting slide groove to move in the horizontal direction, and due to the setting of the magnetic plate 7 and the spring 8, the arc plate 10 is no longer in contact with the lever 9, and the cleaning roller 6 will reset in the horizontal direction. When the main roller 1 continues to rotate, the cleaning roller 6 performs a small reciprocating motion in the horizontal direction while maintaining rotation, so as to continuously clean the outer surface of the main roller 1 to prevent impurities generated during the glass embossing operation from adhering to the arc-shaped outer wall of the main roller 1 and affecting the subsequent normal rolling operation.

[0026] In an embodiment of the utility model, a sleeve 11 is fixedly mounted on the arc-shaped outer wall of the cleaning roller 6, a rotating rod 12 is movably connected to the inner wall of the sleeve 11, an elastic telescopic rod 13 is fixedly connected between the bottom end of the rotating rod 12 and the inner wall of the bottom end of the sleeve 11, a spiral groove 14 is provided on the arc-shaped inner wall of the sleeve 11, a convex ball 15 is fixedly mounted on the arc-shaped outer wall of the rotating rod 12, the convex ball 15 is arranged inside the spiral groove 14, and an arc-shaped steel wire 16 is fixedly mounted on the arc-shaped outer wall of the rotating rod 12.

[0027] Specifically, there are multiple groups of sleeves 11, and the multiple groups of sleeves 11 are evenly distributed in a circular array, so that when the cleaning roller 6 cleans the outer surface of the main roller 1, the wire bristles arranged on its own surface can also obtain a good self-cleaning effect, which is convenient for cleaning and removing glass impurities. At the same time, the inner wall of the sleeve 11 is provided with a transmission hole adapted to the rotating rod 12, and the rotating rod 12 is arranged inside the transmission hole. Furthermore, three groups of arc-shaped steel wires 16 are arranged, and the three groups of arc-shaped steel wires 16 are evenly distributed in a circular array on the arc-shaped outer wall of the rotating rod 12, and the top of the rotating rod 12 is arranged to be spherical. The cleaning roller 6 rotates in the opposite direction to the main roller 1 under the transmission of the driving gear 3 and the driven gear 5. At this time, the outer surface of the main roller 1 slightly squeezes the top of the rotating rod 12. Under the transmission cooperation of the spiral slide groove 14 and the convex ball 15, the rotating rod 12 rotates and moves toward the inner side of the sleeve 11, thereby driving the arc-shaped steel wire 16 to rotate, so as to move the nearby steel wire bristles and sweep off the glass residues on the surface, thereby ensuring the cleaning effect of the cleaning roller 6 on the main roller 1 while avoiding the residual glass slag from damaging the outer surface of the main roller 1.

[0028] In the present invention, when in use, after the calendering operation of the main roller 1 is completed, the cleaning roller 6 is inserted into the installation cylinder 4, and the external power transmission structure is continued to be started to drive the main roller 1 to rotate. At this time, the driving gear 3 and the driven gear 5 are driven to make the installation cylinder 4 drive the cleaning roller 6 to rotate in the direction opposite to the rotation direction of the main roller 1, so as to cooperate with the several steel wire bristles arranged on the arc-shaped outer wall of the cleaning roller 6 to clean the glass residue on the surface of the main roller 1. At the same time, by providing a cleaning component, in cooperation with the continuous rotation of the cleaning roller 6, the lever 9 periodically squeezes and pushes the arc plate 10. With the cooperation of the magnetic plate 7 and the spring 8, the cleaning roller 6 makes a small reciprocating motion in the horizontal direction while keeping rotating, so as to continuously clean the outer surface of the main roller 1, so as to prevent impurities generated during the glass embossing operation from adhering to the curved outer wall of the main roller 1 and affecting the subsequent normal rolling operation. After the cleaning is completed, it is only necessary to push the cleaning roller 6 toward the mounting plate 2 on one side of the main roller 1 so that one end of the cleaning roller 6 is exposed from the mounting tube 4, and then the cleaning roller 6 can be pulled in the reverse direction to disassemble the cleaning roller 6, so as to ensure that the main roller 1 will not be affected by the external structure during operation and can work normally.

[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
