AI Technical Summary
During the uniform winding process of existing waterproof membranes, adjacent layers stick together due to adhesion, affecting storage, transportation, and usage.
The asynchronous control of the reel rotation is achieved by alternately toggling the limit switch on the fixed plate to achieve alternating forward, reverse, and stop rotation of the reel. Combined with the use of a rubber layer and anti-stick powder, adhesion is reduced.
This allows for relaxation between adjacent layers of the waterproof membrane, reducing adhesion, ensuring performance and neatness, and improving the quality of the roll.

Abstract
Description
Technical Field
[0001] This invention relates to the field of waterproof material production technology, specifically to a waterproof roll coiling device and a waterproof roll winding method. Background Technology
[0002] Waterproofing materials are thin, long sheets. During production, the waterproofing material needs to be wound onto a reel to form a complete roll of waterproofing material. The equipment used is a waterproofing material winding device.
[0003] The waterproof membrane winding device includes a frame with a conveying channel for waterproof material and a motor-driven roller at the front end of the frame. During production, the waterproof material is conveyed through the conveying channel and wound onto the roller to form a complete roll of waterproof membrane.
[0004] In the prior art, the motor operates at a constant speed, meaning the waterproof material is wound onto the spool at a constant speed. As a result, the surfaces of adjacent waterproof material layers in the formed waterproof roll are under tension. Due to the high adhesiveness of the waterproof material surface, the layers often stick together during storage and transportation. When using the waterproof roll, separating the stuck parts often tears the waterproof material, affecting its performance. Summary of the Invention
[0005] The purpose of this invention is to address the aforementioned shortcomings by providing a waterproof membrane coiling device and method that reduces adhesion between adjacent layers of the formed waterproof membrane and ensures its effectiveness—an anti-adhesion waterproof membrane coiling device and method.
[0006] The technical solution of the anti-adhesion waterproof membrane coiling device of the present invention is implemented as follows: The anti-adhesion waterproof membrane coiling device includes a device frame, on which a conveying channel for waterproof material is provided. At the front end of the device frame is a motor-driven reel, and the conveying channel conveys the waterproof material from back to front. Its characteristic is that a fixed disc is installed on the reel, the fixed disc is fixed to a rotating shaft and rotates with the fixed disc, and the fixed disc has a fork; a second motor-driven turntable, concentric with the fixed disc, is also installed on the side of the fixed disc, and two limit switches are installed on the turntable. The rotation of the turntable driven by the second motor is asynchronous with the rotation of the reel driven by the motor; for every one revolution of the fixed disc, the fork contacts and actuates each of the two limit switches once, and the limit switches are connected to a control device; the fixed disc... As the disc rotates, the fork sequentially contacts and actuates the first and second limit switches, respectively. When the fork actuates the first limit switch, it transmits a signal to the control device, which then causes the motor to run in the forward direction. When the fork actuates the second limit switch, it transmits a signal to the control device, which then causes the motor to stop or reverse. Forward motor operation means the motor drives the reel to wind the waterproof material; reverse motor operation and forward motor operation are opposite directions. From the moment the fork contacts and actuates the first limit switch to the moment it contacts and actuates the second limit switch, the fixed disc rotates at an angle greater than 180 degrees. From the moment the fork contacts and actuates the second limit switch to the moment it contacts and actuates the first limit switch, the fixed disc rotates at an angle less than 180 degrees.
[0007] Furthermore, from the moment the fork contacts and moves the first limit switch to the moment the fork contacts and moves the second limit switch, the angle of rotation of the fixed disk is greater than 315 degrees; from the moment the fork contacts and moves the second limit switch to the moment the fork contacts and moves the first limit switch, the angle of rotation of the fixed disk is less than 45 degrees.
[0008] To elaborate further,
[0009] Furthermore, the time required for the turntable driven by the second motor to complete one revolution is 4 to 6 times that of the roller driven by the motor.
[0010] Furthermore, the reel also has a rubber layer.
[0011] The technical solution of the waterproof membrane winding method of the present invention is as follows: The waterproof membrane winding method involves winding the waterproof material in a roll. The roll rotates, which allows the waterproof material to be wound on the roll. During the winding process, the roll alternates between forward movement and stop movement, or between forward movement and reverse movement, wherein the time of forward movement is greater than the time of stop movement or reverse movement.
[0012] The beneficial effects of this invention are: such a waterproof membrane coiling device and waterproof membrane winding method have the advantages of loosening between adjacent layers of the formed waterproof membrane, reducing adhesion, and ensuring the effectiveness of use.

[0017] The technical solution of the present invention will be further described below with reference to the embodiments.
[0018] like Figure 1 , 2As shown, the anti-adhesion waterproof membrane coiling device includes a frame 1 with a material conveying channel 2. A reel 4 driven by a motor 3 is located at the front end of the frame. The conveying channel transports the waterproof material from back to front; arrow F in the figure points forward. Its features include: a fixed disc 5 mounted on the reel, which rotates with the reel; a fork 6 on the fixed disc; and a turntable 10 driven by a second motor 9, concentric with the fixed disc, mounted on the side of the fixed disc. Two limit switches 7 are mounted on the turntable. The rotation of the turntable driven by the second motor is asynchronous with the rotation of the reel driven by the motor. With each rotation of the fixed disc, the fork contacts and actuates the two limit switches. The limit switches are connected to a control device 8. As the fixed disc rotates, the limit switches contacted and actuated by the fork sequentially... The first limit switch 71 and the second limit switch 72 are respectively. When the shift fork moves the first limit switch, the first limit switch transmits a signal to the control device, and the control device causes the motor to run in the forward direction. When the shift fork moves the second limit switch, the second limit switch transmits a signal to the control device, and the control device causes the motor to stop running or run in the reverse direction. The forward running of the motor means that the motor drives the roller to wind the waterproof material. The reverse running of the motor means that the motor runs in the opposite direction to the forward running of the motor. When the shift fork moves from contacting and moving the first limit switch to contacting and moving the second limit switch, the fixed disk rotates at an angle α greater than 180 degrees. The roller runs normally during this stage. When the shift fork moves from contacting and moving the second limit switch to contacting and moving the first limit switch, the fixed disk rotates at an angle β less than 180 degrees. The roller runs in a stopped running stage during this stage.
[0019] This winding device is designed to ensure that the loose parts of the waterproof material wound onto the reel are not in a fan-shaped area. In other words, the loose waterproof material (the waterproof material that accumulates when the reel stops or reverses) is evenly distributed around the entire reel of waterproof material, thereby improving the neatness of the winding, achieving a smooth surface of the wound waterproof material, and improving the winding quality.
[0020] According to the instructions, this winding device is designed so that each time waterproof material is wound onto the reel, the reel rotates more than half a turn in the forward direction before stopping or rotating in the reverse direction. This loosens the wound waterproof material and further prevents it from sticking together.
[0021] Figure 1 The direction of the middle arrow 'f' is the direction of rotation of the fixed disk.
[0022] From the moment the shift fork contacts and actuates the first limit switch to the moment the shift fork contacts and actuates the second limit switch, the angle α of the fixed disk rotation is greater than 180 degrees; that is, the angle between the line connecting the first limit switch to the center of the shaft and the line connecting the second limit switch to the center of the shaft is greater than 180 degrees.
[0023] From the moment the shift fork contacts and moves the second limit switch to the moment the shift fork contacts and moves the first limit switch, the angle β of the rotation of the fixed plate is less than 180 degrees; that is, the angle between the line connecting the second limit switch to the center of the shaft and the line connecting the first limit switch to the center of the shaft is less than 180 degrees; the same applies below.
[0024] This ensures that the time for the shaft to rotate in the forward direction is greater than the time for it to rotate in the reverse direction and stop rotating.
[0025] Furthermore, from the moment the shift fork contacts and toggles the first limit switch to the moment the shift fork contacts and toggles the second limit switch, the angle of rotation of the fixed disk is greater than 270 degrees; from the moment the shift fork contacts and toggles the second limit switch to the moment the shift fork contacts and toggles the first limit switch, the angle of rotation of the fixed disk is less than 90 degrees.
[0026] Furthermore, from the moment the fork contacts and moves the first limit switch to the moment the fork contacts and moves the second limit switch, the angle of rotation of the fixed disk is greater than 315 degrees; from the moment the fork contacts and moves the second limit switch to the moment the fork contacts and moves the first limit switch, the angle of rotation of the fixed disk is less than 45 degrees.
[0027] Preferably, the angle of rotation of the fixed disk is greater than 320 degrees from the moment the shift fork contacts and moves the first limit switch to the moment the shift fork contacts and moves the second limit switch; and the angle of rotation of the fixed disk is less than 40 degrees from the moment the shift fork contacts and moves the second limit switch to the moment the shift fork contacts and moves the first limit switch.
[0028] This winding device is designed to ensure that the loose parts of the waterproof material wound onto the reel are not in a fan-shaped area. In other words, the loose waterproof material (the waterproof material that accumulates when the reel stops or reverses) is evenly distributed around the entire reel of waterproof material, thereby improving the neatness of the winding, achieving a smooth surface of the wound waterproof material, and improving the winding quality.
[0029] Furthermore, the time required for the turntable driven by the second motor to complete one revolution is 4 to 6 times that of the roller driven by the motor.
[0030] The above represents the optimal result.
[0031] like Figure 3 As shown, the spool also has a rubber layer 11.
[0032] This winding device is designed in such a way that the waterproof material has a good cushioning effect during winding.
[0033] Furthermore, there is an anti-sticking powder container 12 mounted on the device frame via a spring 13 and above the conveying channel. Below the conveying channel is a screen 14, and a vibration device 15 is mounted on the anti-sticking powder container. The anti-sticking powder container vibrates, and the anti-sticking powder container can sprinkle anti-sticking powder onto the conveying channel.
[0034] The technical solution of the waterproof membrane winding method of the present invention is as follows: The waterproof membrane winding method involves winding the waterproof material in a roll. The roll rotates, which allows the waterproof material to be wound on the roll. During the winding process, the roll alternates between forward movement and stop movement, or between forward movement and reverse movement, wherein the time of forward movement is greater than the time of stop movement or reverse movement.
[0035] Ideally, this device should be used when the waterproof membrane is coiled.
[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
