[0002] In the production process of the coating machine, the treatment of waste materials is a crucial link. When the waste collection device of the traditional coating machine is used to reel in the waste materials, a waste collection tray is usually installed on a rotating shaft. When the waste collection tray is full, the connection structure is loosened to remove the full tray and replace it with a new empty tray. Then, the waste is removed from the full tray. Since the waste is tightly rolled on the tray, it is difficult to remove it. This not only increases the labor intensity of the operator and reduces the work efficiency, but may also affect the normal operation of the coating machine because the waste cannot be removed in time and the tray cannot be replaced. Therefore, it is necessary to solve the above technical problems. Summary of the invention

[0032] Please also read Figures 1 to 3 Now, a waste collection device for a coating machine provided in an embodiment of the present application is described. The waste collection device for a coating machine includes a support shaft 101, a movable shaft 102, a support mechanism and a locking mechanism. Among them:

[0033] The support shaft 101 is used to rotate around its own central axis, and the movable shaft 102 is movably connected to the support shaft 101 and is used to move along the axial direction of the support shaft 101. The support mechanism includes a rotating disk 103 connected to the support shaft 101, a movable seat 104 connected to the movable shaft 102, a coiling arm 105 hinged to the rotating disk 103, and a support arm 106 hinged to the movable seat 104. The support arm 106 is also hinged to the coiling arm 105. The rotation center axes of the support arm 106 and the coiling arm 105 are parallel to each other and perpendicular to the support shaft 101. The locking mechanism is used to lock the movable shaft 102 at a predetermined position on the support shaft 101 so that the coiling arm 105 and the support shaft 101 are parallel to each other, and is also used to release the movable shaft 102 so that the movable shaft 102 can move relative to the support shaft 101.

[0034] According to the above structure provided in the present embodiment, in the waste collection device for the coating machine provided in the present embodiment, when the locking mechanism locks the movable shaft 102 at a predetermined position on the supporting shaft 101 and makes the winding arm 105 parallel to the supporting shaft 101, a plurality of winding arms 105 parallel to and surrounding the supporting shaft form a frame for winding and can rotate with the supporting shaft 101 to roll the coating waste on the outside of the frame to complete the winding operation; after the waste winding is completed, the locking mechanism releases the movable shaft 102 so that the movable shaft 102 can move relative to the supporting shaft 101 along the axial direction of the supporting shaft 101 and make the movable seat 104 connected to the movable shaft 102 away from the rotating disk 103 connected to the supporting shaft 101, The coil arm 105 hinged on the rotating disk 103 can rotate relative to the support arm 106 hinged on the movable seat 104 under the action of the support arm 106 and move itself away from one end of the rotating disk 103 and closer to the center of the supporting shaft 101, even if the frame support area formed by the coil arm 105 for supporting the inner diameter of the material roll shrinks and forms a cone that gradually shrinks outward, the coating waste can be easily removed from the periphery of the coil arm 105, which is far superior to the prior art.

[0035] In another embodiment of the present application, please refer to Figures 1 to 3 The locking mechanism includes a longitudinal groove 107 and a transverse groove 108 which are arranged on the supporting shaft 101 and are vertically connected, and also includes a pin shaft 109 which is connected to the movable shaft 102 and can move in the longitudinal groove 107 and the transverse groove 108. The longitudinal groove 107 extends along the axial direction of the supporting shaft 101, and the transverse groove 108 is connected to one end of the longitudinal groove 107 close to the rotating disk 103.

[0036] According to the above structure provided in the present embodiment, since the transverse groove 108 is perpendicular to the axial direction of the supporting shaft 101, when the pin 109 moves into the transverse groove 108, the movable shaft 102 connected to the pin 109 cannot move along the axial direction of the supporting shaft 101, so that the winding arm 105 and the supporting shaft 101 can maintain a relatively parallel posture; when the pin 109 moves into the longitudinal groove 107, the movable shaft 102 connected to the pin 109 can move along the axial direction of the supporting shaft 101 relative to the supporting shaft 101 and make the movable seat 104 connected to the movable shaft 102 move away from the rotating disk 103, so that the end of the winding arm 105 away from the rotating disk 103 can rotate relative to the support arm 106 and move toward the center of the supporting shaft 101, and the coating waste wound on the periphery of the winding arm 105 can be conveniently removed from the periphery of the winding arm 105.

[0037] In another embodiment of the present application, please refer to Figures 1 to 3A sliding cavity 110 is formed on the support shaft 101 for accommodating the movable shaft 102 and allowing the movable shaft 102 to slide relative to the support shaft 101, and the sliding cavity 110 is connected to the longitudinal groove 107 and the transverse groove 108. According to the above structure provided in this embodiment, the movable shaft 102 is slidably connected to the support shaft 101 through the sliding cavity 110 provided on the support shaft 101, which can not only achieve the technical effect of stable movement of the movable shaft 102 relative to the support shaft 101, but also make the overall structure of the waste collection device for the coating machine provided in this embodiment more concise.

[0038] In another embodiment of the present application, please refer to Figures 1 to 3 The support mechanism further includes a handle 111 connected to the movable shaft 102. According to the above structure provided in this embodiment, the handle 111 connected to the movable shaft 102 can better facilitate the operator to operate the movable shaft 102 to move relative to the support shaft 101.

[0039] In another embodiment of the present application, please refer to Figures 1 to 3 The supporting mechanism further includes a retaining ring 112 detachably connected to the movable shaft 102, and the movable seat 104 is sandwiched between the handle 111 and the retaining ring 112. According to the above structure provided in this embodiment, on the one hand, the movable seat 104 can be stably installed on the movable shaft 102 through the cooperation of the retaining ring 112 and the handle 111, and on the other hand, the movable seat 104 can be more conveniently installed on or removed from the movable shaft 102, which is conducive to making the waste collection device for the coating machine provided in this embodiment more convenient to install and remove.

[0040] In another embodiment of the present application, please refer to Figures 1 to 3 , multiple groups of coiling arms 105 and support arms 106 are evenly arranged around the axial direction of the support shaft 101, and the ends of each group of coiling arms 105 and support arms 106 that are away from each other are respectively and correspondingly hinged on the rotating disk 103 and the movable seat 104, and the adjacent ends are hinged to each other. According to the above structure provided in this embodiment, multiple groups of coiling arms 105 and support arms 106 can form a frame structure for winding support so that the coating machine waste collection device provided in this embodiment can more stably roll up the coating waste. In addition, the ends of multiple groups of coiling arms away from the rotating disk 103 can all move toward the center of the support shaft 101, so that the rolled waste can still be easily removed from the coiling arms, with a better waste winding effect.

[0041] In another embodiment of the present application, please refer to Figures 1 to 3The waste collecting device of the coating machine also includes a driving mechanism for driving the supporting shaft 101, the driving mechanism includes a rotating shaft 113 coaxially connected to the supporting shaft 101, an active friction wheel 114 loosely sleeved on the rotating shaft 113 and capable of rotating around the rotating shaft 113, a passive friction wheel 116 movably connected to the rotating shaft 113 through a connecting key 115 and capable of axially moving along the rotating shaft 113, and a spring 117 connected to the passive friction wheel 116 and used to press the passive friction wheel 116 against the active friction wheel 114, and the rotating shaft 113 is driven by the friction force between the active friction wheel 114 and the passive friction wheel 116. According to the above structure provided in this embodiment, when the active friction wheel 114 rotates around the rotating shaft 113, the friction force between the active friction wheel 114 and the passive friction wheel 116 can drive the rotating shaft 113 to rotate. This can not only drive the rotating shaft 113, but also when an abnormality occurs in the winding process and the supporting shaft 101 and the rotating shaft 113 cannot rotate, the active friction wheel 114 and the passive friction wheel 116 can idle, thereby effectively avoiding overload of the external power source.

[0042] In another embodiment of the present application, please refer to Figures 1 to 3 The driving mechanism further includes a nut 118 threadedly connected to the rotating shaft 113, and the two ends of the spring 117 along its own deformation direction are respectively connected to the nut 118 and the passive friction wheel 116. According to the above structure provided in this embodiment, by rotating the nut 118 relative to the rotating shaft 113, the distance between the nut 118 and the passive friction wheel 116 can be adjusted and the elastic force of the spring 117 can be changed, so that the friction force between the active friction wheel 114 and the passive friction wheel 116 can be conveniently adjusted to adapt to waste coils with different winding tensions, which is conducive to making the waste collection device for coating machines provided in this embodiment suitable for more working scenarios and having better winding quality.

[0043] In another embodiment of the present application, please refer to Figures 1 to 3 The driving mechanism further includes a support 119, a motor 120 mounted on the support 119, and a sprocket 121 idly sleeved on the rotating shaft 113 and coaxially connected to the active friction wheel 114. The motor 120 and the sprocket 121 are connected by a chain 122, and the rotating shaft 113 is rotatably mounted on the support 119. According to the above structure provided in this embodiment, the motor 120 can drive the sprocket 121 idly sleeved on the rotating shaft 113 to rotate through the chain 122 and drive the active friction wheel 114 to idly rotate around the rotating shaft 113, so that the support shaft 101 coaxially connected to the rotating shaft 113 can be stably driven by the motor 120, and has a better winding effect.

[0044] In another embodiment of the present application, please refer to Figures 1 to 3The driving mechanism further includes a first bearing 123 mounted on the support 119 and used to support the rotating shaft 113, and a second bearing 124 connected to the rotating shaft 113 and used to support the active friction wheel 114 and the sprocket 121. According to the above structure provided in this embodiment, the first bearing 123 used to support the rotating shaft 113 and the second bearing 124 used to support the active friction wheel 114 and the sprocket 121 can make the rotation of the rotating shaft 113 and the idling of the active friction wheel 114 and the sprocket 121 relative to the rotating shaft 113 smoother, which is conducive to achieving a better driving effect.
