[0021] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] like Figure 1-3 As shown, a coating film installation device includes a mounting seat 110, a power roller 210, a power device 220, a first tensioning frame 130, a second tensioning frame 140 and an adjusting device 100; the power roller 210 is rotatably mounted on the mounting seat 110; the power device 220 is used to drive the power roller 210 to rotate; the first tensioning frame 130 is hinged on the mounting seat 110, and the first tensioning frame 130 includes a first tensioning roller 132; the second tensioning frame 140 is hinged on the mounting seat 110, and the second tensioning frame 140 includes a second tensioning roller 142; the adjusting device 100 is used to adjust the distance between the first tensioning roller 132 and the second tensioning roller 142, and the power roller 210, the first tensioning roller 132 and the second tensioning roller 142 are used for winding the coating film.

[0023] During use, the distance between the first tensioning roller 132 and the second tensioning roller 142 is increased by the adjusting device 100, so that the coating film wound on the power roller 210, the first tensioning roller 132 and the second tensioning roller 142 can be in a tensioned state as the distance between the first tensioning roller 132 and the second tensioning roller 142 increases. Then, the power roller 210 is driven to rotate by the power device 220, and the coating film is driven and coated under the drive of the power roller 210, so that the loosening of the coating film can be reduced during the coating process to improve the coating effect.

[0024] The power device 220 includes a motor 221, a driving pulley 222, a driven pulley 223, and a transmission belt 224. The motor 221 is used to drive the driving pulley 222 to rotate. The driven pulley 223 is fixed to the power roller 210. The transmission belt 224 is wound around the driving pulley 222 and the driven pulley 223. During use, the motor 221 drives the driving pulley 222 to rotate, which in turn drives the driven pulley 223 and the power roller 210 to rotate via the transmission belt 224.

[0025] Preferably, the coating film installation device includes two power rollers 210, which are rotatably installed on the mounting seat 110 respectively, and a driving pulley 222 is fixed on each of the two power rollers 210; the transmission belt 224 is wound around the driving pulleys 222 of the two power rollers 210.

[0026] The adjusting device 100 includes a rotating body 120, a pawl 151, an elastic component and an elastic reset element 160; the rotating body 120 includes an axle 121, a transmission gear 122 and a ratchet 123; the axle 121 is rotatably mounted on the mounting seat 110; the transmission gear 122 and the ratchet 123 are both fixed on the axle 121; the elastic reset element 160 is arranged between the rotating body 120 and the mounting seat 110; the first tensioning frame 130 is engaged with the transmission gear 122; the second tensioning frame 140 is engaged with the first tensioning frame 130; the pawl 151 is hinged on the mounting seat 110, and the elastic component is arranged between the pawl 151 and the mounting seat 110; the pawl 151 is used to buckle into the tooth groove of the ratchet 123. During use, the operator rotates the axle 121 forward manually or through an external power device 220, and the ratchet 123 and the transmission gear 122 rotate forward along with the axle 121. The first tensioning frame 130 swings under the driving action of the transmission gear 122, and the second tensioning frame 140 swings under the driving action of the first tensioning frame 130. As the first tensioning frame 130 and the second tensioning frame 140 swing, the distance between the first tensioning roller 132 and the second tensioning roller 142 can be adjusted. After the axle 121 rotates into place, the pawl 151 is buckled into the tooth groove of the ratchet 123, thereby playing a locking role, so that the first tensioning frame 130 and the second tensioning frame 140 are kept in place. The pawl 151 is held in the corresponding position, and the pawl 151 is separated from the ratchet 123 by pulling the pawl 151. At this time, the wheel shaft 121 is elastically reset under the elastic force of the elastic reset element 160, and the first tensioning frame 130 is rotated and reset under the driving action of the transmission gear 122. The second tensioning frame 140 is rotated and reset under the driving action of the first tensioning frame 130. In this way, the distance between the first tensioning roller 132 and the second tensioning roller 142 can be flexibly and quickly adjusted, and the coating film wound around the first tensioning roller 132 and the second tensioning roller 142 can be loosened or tightened, making the tension adjustment operation more convenient and quick, saving the tension adjustment time and improving the adjustment efficiency.

[0027] The elastic component includes a spring, which is used to provide an elastic force to cause the pawl 151 to snap into the tooth groove of the ratchet 123, so that when the user pulls the pawl 151 to separate the pawl 151 from the ratchet 123, the axle 121 is elastically reset under the elastic force of the elastic reset element 160, and then by releasing the pawl 151, the pawl 151 can be reset under the elastic force of the spring to snap into the tooth groove of the ratchet 123, thereby further improving the convenience of operation.

[0028] Of course, in addition to the spring, the elastic component can also be any elastic component currently available on the market, such as an elastic strip.

[0029] The elastic return element 160 comprises a coil spring. One end of the coil spring is connected to the axle 121, and the other end is connected to the mounting base 110. This allows the axle 121 to be elastically returned to its original position under the elastic force of the coil spring after the user pulls the pawl 151 to disengage the pawl 151 from the ratchet 123. By using a coil spring as the elastic return element 160, elastic force can be provided to the axle 121 while also facilitating installation.

[0030] Of course, in addition to the coil spring, the elastic reset element 160 can also adopt any existing elastic reset element on the market, such as a torsion spring, etc., as long as it can play an elastic reset role.

[0031] In this embodiment, the coil spring is used to provide an elastic force to urge the axle 121 to rotate and return to the working position. When the axle 121 is in the working position, the distance between the first tensioning roller 132 and the second tensioning roller 142 is the largest. Therefore, after the user pulls the pawl 151 to separate the pawl 151 from the ratchet 123, the axle 121 can be elastically restored to the working position under the elastic force of the coil spring. At this time, the distance between the first tensioning roller 132 and the second tensioning roller 142 is the largest, and the tensioning roller 132 is wound around the movable part. The coating film on the power roller 210, the first tensioning roller 132 and the second tensioning roller 142 is in a tensioned state. During the transmission and coating process of the coating film driven by the power roller 210, the axle 121 remains in the working position under the elastic force of the coil spring, and the first tensioning roller 132 and the second tensioning roller 142 are still at the position with the largest distance between them, so that the coating film is continuously in a tensioned state, thereby further reducing or even avoiding the loosening of the coating film during the coating process.

[0032] The mounting seat 110 is provided with a mounting cavity, and the coil spring is located in the mounting cavity, which facilitates the installation of the coil spring and prevents the coil spring from being exposed.

[0033] Preferably, a first embedding groove is provided on the wheel axle 121, and a second embedding groove is provided on the mounting seat 110. The inner end of the coil spring is fixed in the first embedding groove, and the outer end of the coil spring is fixed in the second embedding groove to facilitate installation.

[0034] The first tensioning frame 130 includes a first toothed plate 131 hingedly connected to the mounting base 110, and a first tensioning roller 132 rotatably mounted on the first toothed plate 131. The first toothed plate 131 is provided with first teeth 133 and meshes with the transmission gear 122. The second tensioning frame 140 includes a second toothed plate 141 hingedly connected to the mounting base 110, and a second tensioning roller 142 rotatably mounted on the second toothed plate 141. The second toothed plate 141 is provided with second teeth 143 and meshes with the first toothed plate 131. During use, the coating film passes around the first and second tensioning rollers 132, 142. During the transmission of the coating film, the first and second tensioning rollers 132, 142, driven by the coating film, can rotate relative to the first and second toothed plates 131, 141, respectively, to reduce friction. During the rotation of the axle 121, the ratchet 123 and the transmission gear 122 rotate with the axle 121, and the first tooth plate 131 of the first tensioning frame 130 swings under the driving action of the transmission gear 122. At this time, the first tensioning roller 132 swings around the hinge point of the first tooth plate 131 along with the first tooth plate 131, and the second tooth plate 141 of the second tensioning frame 140 swings under the driving action of the first tensioning frame 130, and the second tensioning roller 142 swings around the hinge point of the second tooth plate 141 along with the second tooth plate 141, so that the positions of the first tensioning roller 132 and the second tensioning roller 142 can be adjusted.

[0035] In this embodiment, the first tooth plate 131 is hinged to the mounting base 110 via a first pin. The first tooth plate 131 is provided with a first through-hole, and the mounting base 110 is provided with a first mounting hole. The first pin is installed in the first mounting hole and penetrates the first through-hole. In this manner, the first tooth plate 131 is hinged to the mounting base 110, allowing the first tooth plate 131 to swing around the central axis of the first pin. The second tooth plate 141 is hinged to the mounting base 110 via a second pin. The second tooth plate 141 is provided with a second through-hole, and the mounting base 110 is provided with a second mounting hole. The second pin is installed in the second mounting hole and penetrates the second through-hole. In this manner, the second tooth plate 141 is hinged to the mounting base 110, allowing the second tooth plate 141 to swing around the central axis of the second pin.

[0036] Of course, in addition to this, the first tooth plate 131 and the second tooth plate 141 may be hinged to the mounting base 110 through other existing structures.

[0037] A transmission gear 122 is fixed to each end of the wheel axle 121. The first tensioning frame 130 includes two first tooth plates 131, each hinged to the mounting base 110. The first tensioning roller 132 is rotatably mounted on the two first tooth plates 131. The two first tooth plates 131 correspond one-to-one with the transmission gears 122 at each end of the wheel axle 121, and each first tooth plate 131 meshes with the corresponding transmission gear 122. The second tensioning frame 140 includes two second tooth plates 141, each hinged to the mounting base 110. The second tensioning roller 142 is rotatably mounted on the two second tooth plates 141. The two second tooth plates 141 correspond one-to-one with the two first tooth plates 131, and each first tooth plate 131 meshes with the corresponding second tooth plate 141. By adopting the above arrangement, the swing stability of the first tensioning frame 130 and the second tensioning frame 140 can be improved.

[0038] The coating film installation device further includes a guide roller 230 rotatably mounted on the installation seat 110 , and the guide roller 230 is used for winding the coating film around, so that the guide roller 230 can guide the coating film.

[0039] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention.
