Description

Technical Field

[0001] This utility model belongs to the technical field of coating machine, and specifically relates to a winding device for coating machine. Background Technology

[0002] A coating machine, also known as an extrusion casting laminating machine, is a commonly used extrusion molding machine. It is often used in the process of coating large areas of paper or fabric with hot melt adhesive. In cases where paper is used in large areas, the paper will appear in a curled form.

[0003] Therefore, the finished fabric or paper needs to go through a winding process, where the coated paper is rolled into a roll for storage or transportation.

[0004] However, the coated paper needs to be wound onto the take-up drum. During the winding process, the take-up drum needs to be fixed and rotated. The existing method usually uses bolts to move a clamping plate on one side to clamp and fix the take-up drum. When clamping take-up drums of different lengths, the take-up drum will shift, which will affect the winding quality and make it inconvenient to disassemble and install.

[0005] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, they have been modified and improved. At the same time, in the spirit and concept of seeking the best, with the assistance of professional knowledge and experience, and after a lot of ingenuity and experimentation, this utility model was created to provide a winding device for a coating machine to solve the problem. Utility Model Content

[0006] This invention proposes a winding device for a coating machine, which solves the problems in the prior art.

[0007] The technical solution of this utility model is implemented as follows: It includes a base plate and two parallel support plates mounted on the base plate. A first rotating shaft is rotatably mounted on each of the two support plates. A first driving component for rotating the first rotating shaft is detachably mounted on each of the two support plates. At least two keyways are provided on the first rotating shaft. A sliding cylinder is slidably mounted on the first rotating shaft. A key is fixedly mounted inside the sliding cylinder and slidably installed in the keyway. A connecting rod is fixedly mounted at one end of the sliding cylinder. A bushing is rotatably mounted on the outer wall of the sliding cylinder. A second support frame is fixedly mounted on the bushing. Double-threaded rods are rotatably mounted on the two support plates. Second threaded holes are provided on the second support frame. The double-threaded rods are threaded into the two second threaded holes. A second driving component for rotating the double-threaded rod is detachably mounted on each support plate. Activating the second driving component drives the two support frames to move synchronously relative to each other or in opposite directions via the double-threaded rod.

[0008] During use, the above technical solution involves placing the winding drum between two connecting rods, activating the second drive component to drive the two support frames to move synchronously relative to each other or in opposite directions via the double threaded rod, and using the two support frames to drive the two connecting rods to clamp the winding drum, thereby enabling rapid installation and disassembly of the winding drum. This also improves the stability of the clamping, ensuring that the winding drum always remains in the center position, thus improving the winding quality. Furthermore, this solution is suitable for installing winding drums of different lengths.

[0009] Preferably, the double-threaded rod is provided with two external threads with opposite thread directions, and the internal threads of the two second threaded holes are opposite in direction and correspond to the two external threads on the double-threaded rod.

[0010] Preferably, a first support frame is fixedly provided on both support plates, and a second mounting hole is provided on the two first support frames. A second rotating shaft is fixedly provided at both ends of the double threaded rod.

[0013] Preferably, a correction disc is provided between the sliding cylinder and the connecting rod, and the winding drum is clamped and fixed by the two correction discs.

[0014] During use, the above technical solution achieves the function of correcting the deviation of the coated paper during the winding process through the correction discs on both sides, thereby improving the winding quality and neatness, and facilitating storage and use.

[0015] Preferably, the two second support frames are provided with first screw holes, and an adjusting screw is threaded into the first screw holes of the two second support frames. A detection mechanism is rotatably installed at the end of each of the two adjusting screws, and the two detection mechanisms are electrically connected to the two first drive components respectively.

[0016] Preferably, the detection mechanism includes a detection cavity rotatably mounted on the end of an adjusting screw, a second detection contact detachably mounted in the detection cavity, a piston plate slidably mounted in the detection cavity, a first detection contact corresponding to the second detection contact on one side of the piston plate, and a detection rod slidably mounted on the detection cavity on the other side of the piston plate, and an elastic component is provided between the piston plate and the detection cavity.

[0017] Preferably, the length of the portion of the detection rod extending out of the detection cavity is equal to the distance between the first detection contact and the second detection contact.

[0018] During use, the above technical solution involves operating the two detection mechanisms on the second support frame to enable automatic detection of winding drums of different lengths, thereby preventing damage to the winding drums caused by excessive force.

[0019] Preferably, an arc-shaped plate is slidably installed between the two support plates, and a third drive component for synchronous control is provided between the two support plates and the arc-shaped plate.

[0042] Specifically: the second drive component 10 is a forward and reverse servo motor, and the second drive component 10 is mounted on the second support frame 15 by bolts and nuts.

[0043] Both support plates 3 are provided with first mounting holes 4, and the first rotating shaft 12 is rotatably installed in the first mounting holes 4.

[0044] Specifically: the first driving component 13 is a drive motor. The first driving component 13 is mounted on the support plate 3 by bolts and nuts, and its output end is connected and fixed to the first rotating shaft 12.

[0045] There are three keyways 14, which are evenly distributed axially on the first rotating shaft 12. There are three keys 18 on the sliding cylinder 17, which correspond to the keyways 14.

[0046] A guide plate 19 is provided between the sliding cylinder 17 and the connecting rod 20, and the winding drum is clamped and fixed by the two guide plates 19.

[0047] In actual operation: the take-up drum is placed between the two alignment discs 19. The second drive component 10 is activated, which drives the double threaded rod 9 to rotate via the second rotating shaft 11. The double threaded rod 9 drives the two second support frames 15 to move synchronously relative to each other.

A detection rod 2405 slidably mounted on the detection cavity 2401 is fixedly provided on the other side of the piston plate 2402. An elastic member 2406 is provided between the piston plate 2402 and the detection cavity 2401.

[0050] The length of the portion of the detection rod 2405 extending out of the detection cavity 2401 is equal to the distance between the first detection contact 2403 and the second detection contact 2404.

[0051] Specifically: the elastic component 2406 is a return spring. One end of the elastic component 2406 is connected and fixed to the piston plate 2402, and the other end is connected and fixed to the detection cavity 2401. Both the piston plate 2402 and the detection cavity 2401 are insulated.

[0052] In actual operation: The second support frame 15 drives the adjusting screw 23 and the detection mechanism 24 to move synchronously.

[0054] Specifically: the two third drive components 8 are electric push rods or hydraulic cylinders. The third drive components 8 are installed on the support plate 3 by bolts and nuts, and the power end is connected and fixed to the arc plate 7.

[0055] In actual operation: the third drive component 8 is activated to collect the rolled-up coated paper through the arc plate 7, which facilitates unloading.

[0056] The working principle of this utility model is as follows: The take-up drum is placed between two correction discs 19. The second drive component 10 is activated to drive the double threaded rod 9 to rotate through the second rotating shaft 11. The double threaded rod 9 drives the two second support frames 15 to move synchronously relative to each other. The two second support frames 15 drive the sliding drum 17 to rotate along the first rotating shaft 12. The sliding drum 17 drives the key 18 to move along the keyway 14. The two connecting rods 20 are inserted into the take-up drum. At the same time, the correction discs 19 clamp and fix the two ends of the take-up drum. The first drive component 13 is activated to drive the sliding drum 17 to rotate around the bushing 16 through the first rotating shaft 12. The sliding drum 17 drives the correction discs 19 and the take-up drum to rotate, realizing the winding function. The correction discs 19 on both sides realize the correction function of the coated paper during the winding process, improve the winding quality and neatness, and facilitate storage and use.

[0057] The second support frame 15 drives the adjusting screw 23 and the detection mechanism 24 to move synchronously. When the detection rods 2405 on the two detection mechanisms 24 come into contact with each other and push the piston plate 2402 to move along the detection cavity 2401, the piston plate 2402 pushes the first detection contact 2403 to contact the second detection contact 2404 and sends a signal to control the second drive component 10 to stop, realizing the automatic detection function of clamping and fixing the take-up drum. By adjusting the position of the adjusting screw 23 on the second support frame 15, it is suitable for the installation and use of take-up drums of different lengths.
