The clamping blocks 7 are slidably disposed in the clamping grooves 3. One end of the connecting rod 6 is hinged to the clamping block 7, and the other end is hinged to the bearing shell 5. The movement of the bearing shells 5 causes the clamping blocks 7 on both sides of the clamping groove 3 to move closer or further away.

[0016] This embodiment discloses a winding device for waterproof membrane. Its structure includes a mandrel 2 mounted on a rotating support 1. The mandrel 2 is rotatable, and a clamping groove 3 is formed on the mandrel 2 along its axial direction. The clamping groove 3 has a depth. Multiple sliding grooves 4 are provided on both sides of the clamping groove 3 in the direction of the clamping groove 3, and the sliding grooves 4 connect to the clamping groove 3. Two bearings 5 ​​are provided on the side of the mandrel 2, each bearing 5 corresponding to one of the sliding grooves 4 on either side of the clamping groove 3. The bearings 5 ​​can move axially along the mandrel 2 under the drive of a moving drive unit. When the bearings 5 ​​move, the bearings 5... The connecting rod 6, which is hinged to it, drives the clamping block 7, which is hinged to it, to move within the slide groove 4. Within the slide groove 4 on both sides of the clamping groove 3, the clamping block 7 can move closer or further away. When the winding device is in use, one end of the waterproof membrane is inserted into the clamping groove 3, and the clamping blocks 7 on both sides move closer to clamp the waterproof membrane. The mandrel 2 rotates, and the waterproof membrane is wound up on the outer surface of the bearing 5. After winding, the entire roll of waterproof membrane can be unloaded from the mandrel. Therefore, this winding device does not require the insertion of an additional paper tube, which reduces production costs, reduces steps, improves work efficiency, and also avoids workers inserting paper tubes, eliminating safety hazards.

[0017] The moving drive unit includes a moving sleeve 8 and a drive assembly. The moving sleeve 8 is sleeved and slidably disposed on the mandrel 2 near one end of the rotating support 1. The bearing 5 is fixedly disposed on the moving sleeve 8. The drive assembly drives the moving sleeve 8 to reciprocate along the axial direction of the mandrel 2.

[0018] In this embodiment, by connecting the bearing 5 to the movable sleeve 8, a driving component is set to drive the movable sleeve 8 to move along the spindle 2, thereby driving the bearing 5 to move. It should be noted that the movable sleeve 8 is set to two parts, one part being a rotating sleeve and the other part being a non-rotating sleeve. The bearing 5 is connected to the rotating sleeve, which rotates together with the spindle 2. The possible connection method is a spline connection. The rotating sleeve can rotate relative to the non-rotating sleeve, but in the circumferential direction, the non-rotating sleeve restricts the movement of the rotating sleeve. The driving component drives the non-rotating sleeve to move, thereby driving the rotating sleeve to move. The rotating sleeve and the non-rotating sleeve together form the movable sleeve 8. There may be various structural forms between the rotating sleeve and the movable sleeve 8. For example, an inner and outer sleeve structure relationship can be adopted.

[0019] The drive assembly includes a telescopic cylinder 9, a connecting rod 10, and a hinge seat 11. The telescopic cylinder 9 is hinged to the rotating support 1, and the hinge seat 11 is fixedly mounted on the rotating support 1. One end of the connecting rod 10 is hinged to the output end of the telescopic cylinder 9, the middle part of the connecting rod 10 is hinged to the hinge seat 11, and the other end of the connecting rod 10 is hinged to the movable sleeve 8.

[0020] In this embodiment, the drive assembly uses a telescopic cylinder 9 to drive a connecting rod 10, which in turn drives a movable seat to move. Specifically, the telescopic cylinder 9 is hinged to the rotating support 1, and a hinge seat 11 is mounted on the rotating support 1. One end of the connecting rod 10 is hinged to the output end (telescopic end) of the telescopic cylinder 9, the middle part of the connecting rod 10 is hinged to the hinge seat 11, and the other end of the connecting rod 10 is hinged to the movable sleeve 8. When the telescopic cylinder 9 extends or retracts, it drives the connecting rod 10 to swing around the hinge seat 11, and the other end of the connecting rod 10 drives the movable seat to move along the spindle 2. It should be noted that the movable sleeve 8 moves a relatively short distance, and a certain amount of clearance is provided at the hinge between the connecting rod 10 and the movable sleeve 8 to ensure smooth swinging of the connecting rod 10.

[0021] The movable sleeve 8 has hinge holes on both sides, and the connecting rod 10 has two connecting ends near the movable sleeve 8. Each connecting end is equipped with a rolling bearing, which is located inside the hinge hole of the movable sleeve 8.

[0022] In this embodiment, in a possible implementation, the end of the linkage 10 connected to the movable sleeve 8 is configured as a forked fork structure. The linkage 10 is divided into two connecting ends, and a rolling bearing is provided on the connecting end. A hinge hole is provided on the movable sleeve 8, and the rolling bearing is located in the hinge hole. Of course, the linkage 10 can also be connected to the movable sleeve 8 in other ways.

[0023] The spindle 2 is provided with a transmission pulley 12 at one end of the rotating support 1.

[0024] In this embodiment, a transmission pulley 12 is provided on the spindle 2, and the transmission pulley 12 is provided at one end near the rotating support 1 so as to connect to the power through the transmission belt.

[0025] The bearing bush 5 has an arc-shaped structure.

[0026] In this embodiment, the bearing 5 can be configured as an arc-shaped structure, so that when the waterproof membrane is finished being rolled up, it can be directly unwound from the bearing 5 to achieve transfer.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
