As shown in fig. 1, a winding and unwinding device for a coating machine includes a basic frame body 10 as a carrying body, on which left and right frame bodies 110 are arranged at intervals and symmetrically, clamping devices 20 are arranged symmetrically on the inner side walls of the two side frame bodies 110, and the clamping devices 20 are configured to be capable of moving and rotating laterally with respect to the side frame bodies 110, an empty bobbin or a bobbin wound with a blank roll is arranged between the two clamping devices 20, the two clamping devices are closed towards the middle to clamp the empty bobbin or the bobbin wound with the blank roll, and the two clamping devices are separated towards the two sides respectively to separate the empty bobbin or the bobbin wound with the blank roll from the empty bobbin or the bobbin wound with the blank roll; a drive source 30 for rotating the clamp device 20 is disposed on the outer side wall of the side frame body 110; the bearing platform assembly 40 is disposed below the clamping devices 20 and on the inner side wall of the side frame body 110, and is used for bearing the winding drum between the two clamping devices 20, wherein the bearing platform assembly is mainly used for enabling the blank roll on the winding drum to be always attached to the winding drum, and preventing the blank roll on the winding drum from being too fluffy to affect the winding and unwinding actions in the winding or unwinding process.

Referring to fig. 2 and 3, the clamping device 20 includes: the sliding outer sleeve 210 is movably embedded in the side frame body 110, the front part of the sliding outer sleeve is fixedly provided with an auxiliary extending body 211, the auxiliary extending body 211 is connected with the output end of a clamping cylinder 250 through a floating joint 240, the clamping cylinder 250 is fixedly arranged on the side frame body 110, that is, the clamping cylinder 250 controls the sliding outer sleeve 210 to move transversely relative to the side frame body 110; the sliding inner sleeve 220 is rotatably disposed in the sliding outer sleeve 210, for example, a bearing is connected in the sliding outer sleeve, a head end of the sliding inner sleeve 220 is connected to an inflatable chuck 230 through a coupling head 221, that is, the sliding inner sleeve 220 only rotates relative to the sliding outer sleeve 210 without lateral displacement, and the inflatable chuck is a standard component commonly used in the winding and unwinding equipment at present, and performs automatic centering and anti-dropping on an empty reel or a reel wound with a blank roll between two clamping devices by the inflatable chuck.

The clamping cylinder 250 is used for realizing the displacement motion of the sliding outer sleeve 210, so that the sliding inner sleeve 220 synchronously moves along with the sliding outer sleeve, and the inflatable chuck is close to or far away from the end part of the winding drum, thereby realizing the clamping or releasing of the winding drum.

At least one of the inner sliding sleeves 220 is provided at the rear thereof with a sprocket 222, and the sprocket 222 is connected to the output side of the driving source 30 through a belt drive, specifically, a stepping motor, where only one or both of the clamping devices may be provided with the driving source. In the unreeling process, the rotating speed of the driving source can be properly reduced, so that the air expansion chuck on the sliding inner sleeve can be slowly matched with the traction force of the blank roll, the unreeling efficiency is favorably improved, and the rotating speed of the driving source needs to be properly increased in the reeling process, so that the clamping device can overcome the external force to smoothly wind the blank roll on the reel.

Referring to fig. 4 and 5, the platform assembly 40 comprises: a seat 410 horizontally installed below the clamping device 20 on the inner sidewall of the side frame 110; a pair of platform clamping plates 420 arranged above the base body 410 in a mirror image interval manner, wherein the upper main part of the platform clamping plates 420 is provided with a triangular clamping part, the inclined planes of the two clamping parts are opposite, and the inclined plane inclination angle of the clamping part is preferably set to be 45 degrees; the baffle 430 is disposed on one side of the bearing platform clamp 420 and keeps a certain distance from the bearing platform clamp 420, and the baffle is used to ensure that the side edge of the blank roll wound on the winding drum is always kept orderly, that is, the distance between the two baffles should be basically consistent with the length of the blank roll on the winding drum, so that the blank roll on the winding drum is always limited by the baffles, and the blank roll is effectively prevented from being out of alignment.

Further, the two platform jaws 420 are preferably configured to move toward and away from each other, such that when the roll on the roll is placed between the jaws of the two platform jaws, the two platform jaws will exert a squeezing action on the roll, and the roll will be tightly held against the roll during either unwinding or winding; specifically, the bottom of the platform clamp plate 420 is provided with a sliding body 421, the sliding body 421 is slidably disposed in the seat body 410, the sliding bodies 421 of the two platform clamp plates 420 are together sleeved on a guide rod 440, a return spring 441 is disposed at the middle position of the guide rod 440, and two ends of the return spring 441 are respectively connected with one sliding body 421; inside the housing 410, a push-pull body 450 is disposed to force the two sliders 421 to move toward or away from each other.

Furthermore, the lower part of the sliding body 450 is convexly provided with a contact part 422, and the outer side edge of the contact part 422 is designed into a curved surface structure with smooth transition; the two sides of the push-pull body 450 are provided with limit parts 451, and the push-pull body 451 reciprocates under the action of a bearing platform cylinder 460; in the natural state of the return spring 441, the lower edge of the contact portion 422 of the sliding body 421 does not exceed the inner sidewall of the limiting portion 451.

When the push-pull body 450 is pushed by the bearing platform cylinder 460 to move toward the sliding body 421, the two limiting portions 451 respectively contact with one of the contact portions 422 until the contact portions 422 are forced to move toward the middle, at this time, the distance between the two bearing platform clamping plates 420 is shortened, and the clamping action on the blank roll on the winding drum can be realized, and conversely, when the push-pull body 450 is driven by the bearing platform cylinder 460 to move away from the sliding body 421, the two limiting portions 451 return to the initial positions under the action of the return spring 441, and at this time, the distance between the two bearing platform clamping plates 420 is lengthened.

In order to ensure that the tension of the blank roll is constant when the blank roll is wound or unwound, at least one conveying roller needs to play a tensioning role, and the other conveying rollers are used for changing the winding direction of the blank roll, as shown in fig. 6, specifically, the end of at least one conveying roller 50 is slidably clamped on a vertical guide rail 510, and the vertical guide rail 510 is slidably clamped on a transverse guide rail 520; the amount of displacement in the vertical direction of the transfer roller 50 is adjusted by a vertically adjustable screw 530 and the amount of displacement in the horizontal direction of the transfer roller 50 is adjusted by a horizontally adjustable screw 540, that is, the transfer roller can be changed in the horizontal or longitudinal direction by a small amount to adjust the tension around the transfer roller.

As shown in fig. 1, a sensor holder 120 is mounted above the space between the two side frame bodies 110, a roll diameter sensor 121 is disposed on the sensor holder 120, and the roll diameter sensor 121 faces toward the middle between the two clamps 20. The thickness condition of the blank roll on the winding drum between the two clamping devices is automatically judged through the roll diameter sensor so as to stop the unwinding or winding action in time, and of course, the thickness change of the blank roll on the winding drum can be directly observed by naked eyes when the judgment is made, but the waste of manpower is caused.
