Description

Technical Field

[0001] The present invention relates to the technical field of winding, and particularly to a double-station non-stop automatic winder. Background Art

[0002] In the winding part of a coil material processing production line, raw materials are wound into coil materials mechanically, which are widely used in paper coil, cloth coil, plastic coil, and metal coil processing production lines. They are designed diversely according to actual process requirements. Common ones include simple winders, hydraulic winders, etc.

[0003] In traditional production, the winding of materials is mostly batch-based. That is, after the materials are wound, the winder stops operating, releases the coil, and then continues the winding operation. This type of winding operation method requires stopping the material transfer. In the fabric processing industry, the production line is relatively long. If the operation is stopped, it will undoubtedly cause losses. The existing solution for fabric winding is to add a cloth storage rack in the production line to provide a time window for the winder to release the coil, but it also increases the length of the production line. Summary of the Invention

[0004] To solve the above problems, the present invention discloses a double-station non-stop automatic winder, including a frame. A rotating frame is rotatably connected to the upper end of the frame. The rotating frame includes a central rotating shaft and support arms radially connected to the ends of the rotating shaft. Clamping and disengaging mechanisms are provided at both ends of the support arms. A winding roller is arranged between two coaxial clamping and disengaging mechanisms. Clamping and disengaging mechanisms and winding rollers are provided at the ends of the support arms, namely double stations, and the fabric is wound around the winding roller.

[0005] A first shaft and a second shaft are coaxially nested inside one end of the rotating shaft. The first shaft and the second shaft are respectively connected to the clamping and disengaging mechanisms through sprockets and chains. The first shaft and the second shaft respectively correspond to a clamping and disengaging mechanism, and the winding rollers of each station are independently controlled to rotate.

[0006] Preferably, the clamping and disengaging mechanism includes a rotating sleeve rotatably fitted on the support arm. A clamping rod is axially slidably fitted inside the rotating sleeve. Spline segments are provided on the side wall of the clamping rod and the inner wall of the rotating sleeve. A fourth cylinder is arranged at one end of the rotating sleeve. The output end of the fourth cylinder is axially fitted with the clamping rod. The axial fit here means that the output end of the fourth cylinder can push and pull the clamping rod, but the rotation of the clamping rod will not be affected. It can be understood that they are fitted in the way of a convex ring and a circular groove. When winding, the fourth cylinder acts to push the clamping rod to move axially, clamp and fix the winding roller. At this time, the spline segments on the clamping roller and the rotating sleeve coincide, and driving the rotation of the rotating sleeve drives the rotation of the winding roller.

[0007] Preferably, an engaging cutting mechanism is provided at the lower front part of the frame, and the engaging cutting mechanism comprises a first rotating arm, a first cylinder, a second rotating arm, a second cylinder, a third rotating arm and a third cylinder, one end of the first rotating arm is a first rotating point, and the output ends of the first rotating arm and the first cylinder are both rotatably connected to the frame by means of the first rotating point, and at the same time, the cylinder end of the first cylinder of the first cylinder is rotatably matched to the frame; The middle part of the first rotating arm is rotatably connected to the second rotating arm, the first rotating arm is rotatably connected to the second cylinder, and the output end of the second cylinder is rotatably connected to the second rotating arm; The third rotating arm is provided with a second rotating point, and the output ends of the third rotating arm and the third cylinder are both rotatably connected to the second rotating arm by means of the second rotating point, and the third cylinder is rotatably connected to the second rotating arm. The first rotating arm, the second rotating arm, and the third rotating arm, under the action of the first cylinder, the second cylinder, and the third cylinder, hold the fabric on the winding roller.

[0008] Preferably, the third rotating arm is provided with a cutting unit, which includes a screw, a slider matched with the screw, a cutter on the slider, and a motor driving the screw to rotate. When the fabric is embraced on the winding roller, the cutting unit cuts the fabric, and then the winding roller rotates to wind the fabric.

[0009] Preferably, one end of the rotating shaft is fixedly connected to a worm wheel, and a worm is provided below the worm wheel. A rotating motor is fixedly connected to one side of the frame, and a chain and a sprocket are used to drive the output end of the rotating motor and the worm. When the rotating motor is started, the rotating frame is rotated under the transmission of the chain, sprocket, worm and worm wheel.

[0010] Preferably, a winding motor is fixedly connected to one side of the frame, and the winding motor is connected to the first shaft or the second shaft through a chain, a sprocket, and a transmission. Two winding motors are provided here, and starting one of the motors drives the action of the corresponding clamping clutch mechanism, that is, the winding operation of the corresponding workstation.

[0011] The beneficial effects of the present invention are as follows: 1. There are two workstations on the rotating frame. When one workstation is rewinding, the other workstation can release the coil to meet the non-stop production of the production line and optimize the production line. At the same time, each workstation is driven independently.

[0012] 2. Equipped with a clamping and cutting mechanism, a clamping and clutching mechanism, a rotating motor, a winding motor and other components, this winder can achieve fully automated operation. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0015] The present invention will be further clarified below in conjunction with the accompanying drawings and specific implementation manners. It should be understood that the following specific implementation manners are only used to illustrate the present invention and not to limit the scope of the present invention. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0016] As Figures 1 to 6 shown, a double-station non-stop automatic winding machine includes a frame 1. A rotating frame 4 is rotatably connected to the upper end of the frame 1. The rotating frame 4 includes a rotating shaft in the middle and support arms radially connected to the ends of the rotating shaft. Clamping and disengaging mechanisms 9 are provided at both ends of the support wall, that is, two workstations are provided. A winding roller 5 is provided between the two coaxial clamping and disengaging mechanisms 9, and the winding roller 5 is used for winding the fabric. In addition, a support rod is vertically connected to the middle of the support arm, and a guide roller is provided at the end of the support rod to prevent the fabric from contacting the rotating shaft during the rotation of the rotating frame 4.

[0017] A first shaft 10 and a second shaft 11 are coaxially nested inside one end of the rotating shaft. The first shaft 10 and the second shaft 11 are respectively connected to the clamping and disengaging mechanism 9 through sprockets and chains. That is, the clamping and disengaging mechanisms 9 at the two workstations are independently driven, and bearings are provided between the first shaft 10, the second shaft 11, etc.

[0018] The clamping and clutch mechanism 9 includes a rotating sleeve 93 rotatably fitted on the support arm. A sprocket is provided on the side wall of the rotating sleeve 93. That is, the first shaft 10 or the second shaft 11 drives the rotating sleeve 93 to rotate. An axially slidable clamping rod 91 is provided inside the rotating sleeve 93. That is, the clamping rod 91 can extend out from the inside of the rotating sleeve 93. The end of the clamping rod 91 is stepped. When winding the winding roller 5, the radial movement of the winding roller 5 is restricted. Spline segments 92 are provided on the side wall of the clamping rod 91 and the inner wall of the rotating sleeve 93. When the spline segments 92 of the two coincide, that is, the clamping function 91 and the rotating sleeve 93 are linked. A fourth cylinder 94 is provided at one end of the rotating sleeve 93. The output end of the fourth cylinder 94 is axially fitted with the clamping rod 91. The meaning of axial fitting is that the output end pushes and pulls the clamping rod 91 without affecting the rotation of the clamping rod 91. When the fourth cylinder 94 operates, the clamping rod 91 clamps the winding roller 5, and at the same time the spline segments 92 coincide, driving the rotating sleeve 93 to rotate to realize the winding of the fabric.

[0019] At the lower part of the front of the frame 1, a clamping and cutting mechanism 7 is provided. The clamping and cutting mechanism 7 includes a first rotating arm 72, a first cylinder 73, a second rotating arm 78, a second cylinder 79, a third rotating arm 77 and a third cylinder 74. One end of the first rotating arm 72 is a first rotation point 71. And both the first rotating arm 72 and the output end of the first cylinder 73 are rotatably connected to the frame 1 by means of the first rotation point 71. At the same time, the cylinder end of the first cylinder 73 of the first cylinder 73 is rotatably fitted on the frame 1. When the first cylinder 73 operates, the first rotating arm 72 can rotate around the first rotation point 71.

[0020] The middle of the first rotating arm 72 is rotatably connected to the second rotating arm 78. A second cylinder 79 is rotatably connected to the first rotating arm 72. The output end of the second cylinder 79 is rotatably connected to the second rotating arm 78. When the second cylinder 79 operates, the second rotating arm 78 rotates.

[0021] A second rotation point 75 is provided on the third rotating arm 77. And both the third rotating arm 77 and the output end of the third cylinder 74 are rotatably connected to the second rotating arm 78 by means of the second rotation point 75. The third cylinder 74 is rotatably connected to the second rotating arm 78. When the third cylinder 74 operates, the third rotating arm 77 rotates around the second rotation point 75, and the winding roller 5 can be clamped in the space between the second rotating arm 78 and the third rotating arm 77. It should be noted that pressure rollers are provided on both the second rotating arm 78 and the third rotating arm 77. When clamping, the pressure rollers press the fabric against the winding roller 5.

[0022] A cutting unit 76 is provided on the third rotating arm 77. The cutting unit 76 includes a screw, a slider fitted on the screw, a cutter on the slider, and a motor for driving the screw to rotate. After the fabric is clamped and wound, the cutting unit 76 operates to cut the fabric. Then the winding roller 5 rotates to wind. When the fabric is wrapped around the winding roller 5, at this time the clamping and cutting mechanism 7 resets, specifically asFigure 3 shown.

[0023] One end of the rotating shaft is fixedly connected with a worm wheel 3, and a worm 8 is arranged below the worm wheel 3, and the worm 8 is rotatably matched with the frame 1. The design of the worm wheel 3 and the worm 8 is that the mechanism has the advantage of one-way transmission, and the posture can be kept unchanged even when the load of the rotating frame 4 changes continuously. A rotating motor 2 is fixedly connected to one side of the frame 1, and the output end of the rotating motor 2 and the worm 8 are driven by a chain and a sprocket. When the rotating motor 2 is started, the rotating member 4 is driven to rotate.

[0024] A winding motor 6 is fixedly connected to one side of the frame 1, and the winding motor 6 is connected to the first shaft 10 or the second shaft 11 through a chain, a sprocket. Similarly, starting the winding motor 6 drives the corresponding winding roller 5 to rotate to perform the fabric winding operation.
