[0030] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0031] like Figure 1-Figure 5 As shown, the present invention provides a tension detection roller that quickly switches between active and passive modes. It is used to control the tension of films, paper, textiles, or other materials during the coating process to ensure stability and quality. The device comprises a frame 100 for mounting components, a switching roller assembly 200, a first active roller 300, and a second active roller 400 mounted on the frame 100. The switching roller assembly 200 includes a switching roller 201 and a gap adjustment power assembly 500.

[0032] The frame 100 is a frame structure, equipped with a support base and two opposing side panels 101 mounted on the support base. The switching roller 201, the first active roller 300, and the second active roller 400 are arranged parallel to each other from left to right between the two side panels 101, serving as a feed channel for the material 000. The material 000 is fed from the left feed mechanism and discharged from the switching roller 201 or the second active roller 400. Furthermore, to protect the coating material on the surface of the material 000, the switching roller 201, the first active roller 300, and the second active roller 400 are staggered slightly, forming a small wrap angle with the material 000.

[0033] One side of the switching roller 201 passes through the side plate 101 and is connected to a driven gear 202 .

[0034] The gap adjustment power assembly 500 is located between the driven gear 202 and the first active roller 300 and includes a gap adjustment drive cylinder 501, a bearing plate 502, a driving gear 503, two tensioning wheels 701, and a guide frame. The guide frame includes two frames 5041 and two guide rods 5042.

[0035] Two frames 5041 are mounted on the side plate 101, with one frame 5041 located on the side of the driven gear 202 away from the first driving roller 300, and the other frame 5041 located on the other side of the driven gear 202 closer to the first driving roller 300. Two guide rods 5042 are spaced apart and arranged parallel to each other between the two frames 5041. The two guide rods 5042 extend through the support plate 502, and the support plate 502 moves toward or away from the driven gear 202 along the guide rods 5042. The driving gear 503 is mounted on the support plate 502, and two tensioning pulleys 701 are mounted on the support plate 502, one above and one below the driving gear 503. The fixed end of the clearance adjustment drive cylinder 501 is connected to the side plate 101, and its driving end is connected to the support plate 502 through the avoidance hole on the frame 5041 adjacent to it. The clearance adjustment drive cylinder 501 drives the driving gear 503 and the two tensioning wheels 701 on the support plate 502 to move closer to or away from the driven gear 202. When the driving gear 503 and the driven gear 202 are against each other, the two are engaged.

[0036] Preferably, two stoppers 505 are symmetrically disposed on the side panel 101 between the two frames 5041. The two stoppers 505 are located on the sides of the two guide rods 5042 that are spaced apart from each other. When the support plate 502 moves toward the driven gear 202, and the driven gear 503 abuts the driven gear 202, the two stoppers 505 abut against the support plate 502, stopping the support plate 502 there.

[0037] In addition, to be connected to the synchronous belt 600 described below, a synchronous wheel 601 is further connected to the top surface of the driving gear 503. One end of the first driving roller 300, the second driving roller 400 and the switching roller 201 on the same side passes through the side plate 101 and is respectively connected to a synchronous wheel 601.

[0038] A support frame is also provided on the side plate 101, located on one side of the synchronous pulley 601 on the second active roller 400. The support frame comprises four support rods 801 perpendicularly connected to the outer side of the side plate 101. The four support rods are arranged in a rectangular matrix, and the top surfaces of the four support rods 801 are fixedly connected to a mounting plate 802. The fixed end of the drive motor 401 is mounted on the mounting plate 802, while its driving end passes through the mounting plate 802 and is connected to a reducer 402. The other end of the reducer 402 is connected to a coupling 403, the other end of which is connected to one end of the second active roller 400. The second active roller 400 is driven in rotation by the drive motor 401.

[0039] Several tensioning pulleys 701 are staggered vertically on the side plate 101, located between the gap adjustment power assembly 500 and the first active roller 300, and between the first active roller 300 and the second active roller 400. In the present invention, a tensioning pulley is provided between the driving gear 503 and the synchronous pulley 601 on the first active roller 300, and two tensioning pulleys 701 are staggered vertically between the synchronous pulley 601 on the first active roller 300 and the synchronous pulley 601 on the second active roller 400.

[0040] In order to realize the transmission connection between the switching roller assembly 200, the first active roller 300 and the second active roller 400, the synchronous belt 600 is sequentially wrapped around the synchronous pulley connected to the second active roller 400, the two tensioning pulleys between the second active roller 400 and the first active roller 300, the synchronous pulley 601 on the first active roller 300, an tensioning pulley 701 between the first active roller 300 and the gap adjustment power assembly 500, and then wrapped around the tensioning pulley 701 connected to the carrier plate 502 and the synchronous pulley 601 on the driving gear 503. Therefore, when the drive motor 401 drives the second active roller 400 to rotate, the first active roller 300 and the driving gear 503 rotate synchronously.

[0041] Preferably, a protective cover 102 is provided on the side plate 101 connected to the gap adjustment power assembly. The protective cover 102 encloses the driven gear 202, the gap adjustment power assembly, the tensioning pulley 701, the timing belt 600, and the timing pulley 601. The aforementioned mounting plate 802 is provided on the outer surface of the protective cover 102. The fixed end of the drive motor 401 is provided on the outer surface of the mounting plate 802. The drive end of the drive motor 401 passes through the mounting plate and the protective cover 102 in sequence and is connected to the second active roller 400.

[0042] The operation process of the utility model is as follows:

[0043] The fast-switching active and passive tension detection roller of the present invention is provided with two material feeding channels, material feeding channel A and material feeding channel B. According to different material processes in actual production, the operator can select material feeding channel A and material feeding channel B on the human-machine interface, wherein the length of material feeding channel A is greater than the length of material feeding channel B.

[0044] The running process of material 000 through feeding channel A: material 000 enters from the left side of switching roller 201, and is placed on the surface of switching roller 201, first active roller 300 and second active roller 400 in sequence, and is discharged from the second active roller 300; because in feeding channel A, the wrap angle between material 000 and it is very small, in order to avoid scratches on the surface of material 000 due to inconsistent linear speed on switching roller 201, switching roller 201 needs to be switched to active roller, that is, a driving roller with power, to ensure that its linear speed is consistent with the linear speed of material 000.

[0045] Start the gap adjustment drive cylinder 501, which drives the driving gear 503 to move toward the driven gear 202 on the switching roller 201 until the driving gear 503 engages with the driven gear 202; start the drive motor 401, and the switching roller 201, the first active roller 300 and the second active roller 400 rotate synchronously through the synchronous belt 600, driving the conveying material 000.

[0046] The running process of material 000 through feeding channel B: material 000 enters from the left side of switching roller 201, is placed on the surface of switching roller 201, and is discharged from the right side of the surface of switching roller 201. The path of this process is short, and the angle between material 000 and switching roller 201 is large; at this time, switching roller 201 needs to be used as a tension roller to control the tension control in the feeding channel B process; in this process, the gap adjustment drive cylinder 501 drives the driving gear 503 to move away from the driven gear 202. At this point, the switching roller 201 is driven to rotate by the feed roller at the feed end and the adsorption roller at the discharge end in the coating equipment to control the tension of material 000 during the feeding process.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
