[0002] When the PVC coating machine produces base fabric sizing products, some products need to be surface treated. The surface treatment agent is attached to the product surface through the rotation of the roller. Traditional surface treatment rollers are mostly supported by four bearings and powered by a motor.

[0003] However, this fixing method has certain defects in actual use. The roller shaft is subjected to greater force during rotation, thereby increasing the wear rate. At this time, due to the different degrees of wear on both sides of the roller shaft, there are fluctuations during rotation, making the thickness of the surface treatment agent attached to the product surface uneven, and the product quality does not meet the requirements, resulting in waste. Utility Model Content

[0004] The purpose of the present invention is to provide a roller fixing device to solve the problems raised in the above background technology.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 5 The utility model provides an embodiment: a roller fixing device, including a roller 2 for applying sizing to the surface of a PVC coating machine. The surface agent is attached to the surface of the product by the rotation of the roller 2. A rotating rod 3 is provided in the middle of the roller 2, and its two ends are assembled on the mounting frame 4 through fixed bearings 13, which can be easily rotated on the mounting frame 4, and the mounting frame 4 is welded to the base 1 (a partial diagram of the coating machine, a relatively mature technology, which will not be described here).

[0021] See also Figure 1-Figure 5 In order to ensure the uniform thickness of the surface agent attached to the product surface, the degree of wear on both sides tends to be the same, and the stability of the rotation process, the two ends of the base 1 are symmetrically welded with fixed seats 6, on which the motor 5 is installed to ensure the stability of the motor 5 during operation. The output end of the motor 5 and the two ends of the rotating rod 3 are provided with connecting holes 16. The two connecting holes 16 at the same end are plugged with connecting pieces 17, and the outer sleeve is provided with a rubber sleeve 18 to ensure a firm plug-in. In actual use, only the connecting piece 17 at one end is inserted into the connecting hole 16, and the other end is plugged in. The plug-in can be replaced every one or two hours, and the drive is alternated. The master and slave are driven, so that the degree of wear on both sides tends to be the same, ensuring the stability of the rotation process. The interval time can also be other times, which can be adjusted according to actual conditions. It is in a stopped state when switching. In order to facilitate the switching operation, the base 1 is vertically welded with a vertical plate 7, and electric push rods 19 are symmetrically installed on the side walls of the vertical plate 7. The output end of the electric push rod 19 is installed with a top plate 20. A card slot 21 matching the connecting piece 17 is opened on the side wall of one of the top plates 20, which can be conveniently clamped and temporarily placed. In order to ensure the clamping effect, an elastic pad is bonded to its inner wall, which does not affect the subsequent insertion into the connecting hole 16 and then the removal operation.

[0022] See also Figure 1-Figure 5In order to facilitate the regular replacement of the fixed bearing 13, ensure its stability during rotation, and further ensure the uniform thickness of the surface agent attached to the product surface, two groups of hydraulic telescopic rods 8 are symmetrically provided on the base 1 (located between the two mounting frames 4). The output ends of the two hydraulic telescopic rods 8 at the same end are commonly provided with a support plate 9. An arc-shaped groove adapted to the rotating rod 3 is opened in the middle of the top of the support plate 9, and a rubber pad 11 is bonded in the arc-shaped groove, which can facilitate the lifting of the rotating rod 3. In order to facilitate the positioning and fixing of the fixed bearing 13 and ensure the stability of rotation, two groups of L-shaped rods 12 are symmetrically welded on the support plate 9. A positioning block 10 is welded on the top of the L-shaped rod 12, and a positioning block 10 is welded in the middle of its inner arc surface (adapted to the outer ring of the fixed bearing 13). The corresponding outer ring of the fixed bearing 13 is provided with a plug-in slot 14 that is plugged into the plug-in block 15 to ensure the stability of the fixed bearing 13 when placed.

[0023] When the utility model is in use, the electric push rod 19 at one end is extended (with a card slot 21), and the connecting piece 17 on the top plate 20 is moved and inserted into the connecting hole 16. A group (can be the left end or the right end, only one end is plugged in, and the other end is replaced and plugged in after one end is used for a period of time) of the output end of the motor 5 is plugged and fixed with the rotating rod 3. The rubber sleeve 18 can ensure the effect of the plugging. Then the electric push rod 19 is retracted and reset, and the top plate 20 is away from the connecting piece 17, which does not affect the subsequent rotation. The end plugged in with the motor 5 is the active end, and the other end not plugged in is the slave end. The active end, through the work of the motor 5, can drive the rotating rod 3 to rotate in the fixed bearing 13, and then drive the roller 2 to rotate to facilitate the processing operation. After working for a period of time, it stops working. At this time, the electric push rod 19 at the other end is extended (with a card slot 21) to repeat the above steps, and the driven end (the other end not connected to the motor 5) is plugged and connected. At this time, the electric push rod 19 at the active end (without a card slot 21) is extended, and the top plate 20 is moved, and the connecting piece 17 can be pushed out and pushed into the inside of the card slot 21. At this time, the active end becomes the driven end, and the motor 5 at the other end works. The processing operation can be continued, and the master-slave alternation mode at both ends can be adopted, so that the wear degree of both sides tends to be the same, ensuring the stability of the rotation process and the uniform thickness of the surface agent attached to the product surface. At the same time, the traditional four-bearing support is changed to two fixed bearings 13 support, the force on the roller 2 is reduced, and the wear degree of the wheel is greatly reduced. When the fixed bearing 13 needs to be repaired or replaced after a period of use, the hydraulic telescopic rod 8 is extended, and the support plate 9 is moved up. At this time, the L-shaped rod 12 and the positioning block 10 are moved up, and the plug-in block 15 leaves the plug-in slot 14, losing the fixed bearing 13. The fixed bearing 13 is limited, and then continues to move upward. The support plate 9 cooperates with the rubber pad 11 to lift the rotating rod 3, and then the whole can be lifted out of the mounting frame 4, and the fixed bearing 13 is moved out of the mounting frame 4, which makes it convenient to repair or replace the fixed bearing 13, which is more convenient. After the operation is completed, the hydraulic telescopic rod 8 is retracted and reset, and it is moved into the mounting frame 4, and then the support plate 9 is continued to move downward to leave the rotating rod 3, and continue to move downward with the positioning block 10. The plug-in block 15 enters the plug-in slot 14, which can limit and fix the outer ring of the fixed bearing 13 to ensure stability during work.

[0024] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
