[0027] In order to further illustrate the technical means and effects of the utility model for achieving the predetermined utility model purposes, the specific embodiments, structures, features and effects according to the utility model are described in detail as follows in combination with the preferred embodiments and the drawings.

[0028] Please refer to Figures 1-8 The purpose of the present embodiment is to provide a kind of waterproof breathable film intelligent slitting equipment of adjustable spacing, including rack 1, rack 1 is rotatably installed with roll 2 and several guide rollers 4, the top of rack 1 is symmetrically fixedly connected with fixed plate 11, connecting rod 3 is slidably arranged between fixed plate 11, several cutters 5 are slidably arranged on connecting rod 3, distance adjusting cylinder 6 is arranged between adjacent two cutters 5, distance adjusting cylinder 6 is used to adjust the cutting width of waterproof breathable film, roll 2 is provided with adjusting part 7 for fixing waterproof breathable film of different width.

[0029] The distance adjusting cylinder 6 comprises an outer cylinder 61 and an inner cylinder 62 slidingly arranged in the outer cylinder 61, the inner cylinder 62 penetrates the connecting rod 3 and slides thereon, a plurality of grooves 612 are formed in the top of the outer cylinder 61, and a sliding block 611 is slidingly arranged in each groove 612.

[0030] The lower end of each sliding block 611 is fixedly connected with a limiting block 6111, the limiting block 6111 is slidingly installed in the sliding groove 613, a spring 614 is arranged in the sliding groove 613, one end of the spring 614 is fixedly connected with the upper wall of the sliding groove 613, and the other end of the spring 614 is fixedly connected with the upper surface of the limiting block 6111, so that the sliding block 611 can be kept at a stable position when not affected by external force, as shown in Figure 4

[0031] A plurality of limiting grooves 621 are formed in the top of the inner cylinder 62, an elastic block 622 is arranged in each limiting groove 621, the lower surface of the elastic block 622 is fixedly connected with the lower surface of the limiting groove 621, a connecting block 623 is fixedly connected with the top of the elastic block 622, the connecting block 623 is triangular, and the connecting block 623 is slidingly inserted into the lower end of the groove 612, as shown in Figure 6 The right side is the original position of the connecting block 623 and the elastic block 622 in the limiting groove 621 when not affected by external force, and the left side is the position of the connecting block 623 and the elastic block 622 in the limiting groove 621 when affected by external force, and the elastic block 622 has good contraction force.

[0032] Before starting the adjustment, the inner cylinder 62 is completely located outside the outer cylinder 61, when it is necessary to adjust the length of the distance adjusting cylinder 6, the inner cylinder 62 is inserted into the outer cylinder 61, as the inner cylinder 62 gradually penetrates,

[0033] The inclined surface of the connecting block 623 first contacts the inner wall of the outer cylinder 61, due to the design of the inclined surface, the connecting block 623 will retract into the limiting groove 621 when being pressed, and at the same time, the elastic block 622 is deformed, when the inner cylinder 62 continues to slide, the connecting block 623 approaches and aligns with the sliding groove 613, the elastic block 622 starts to push the connecting block 623 to slide upward due to its restoring force, the top of the connecting block 623 gradually extends out of the limiting groove 621, and finally is clamped in the groove 612, at this time, the relative position of the inner cylinder 62 and the outer cylinder 61 is locked, in this process, the upper surface of the connecting block 623 will contact the sliding block 611 and lift the sliding block 611 upward by a part, at the same time, the limiting block 6111 in the sliding groove 613 also slides upward.

[0034] ​If the initial locking position results in the length of the distance adjusting cylinder 6 being too long or not meeting the requirements, it can be adjusted manually. Press the exposed part of the connecting block 623 slightly downward to overcome the restoring force of the elastic block 622, release it from the groove 612, continue to slide the inner cylinder 62 inward until the connecting block 623 is aligned with the next suitable groove 612, and repeat the locking process described above. When the inner cylinder 62 is slid to the desired position and successfully locked, the length of the distance adjusting cylinder 6 is determined, and at this time, the distance between the two adjacent cutters 5 is also determined, so that the waterproof and breathable film can be cut into the appropriate width.

[0035] The connecting rod 3 slides vertically on the fixed plate 11, and the top of the fixed plate 11 is provided with a power source, which is preferably a micro motor. The motor drives the connecting rod 3 to slide downward to approach the roller 2 for cutting the waterproof and breathable film.

[0036] The adjusting part 7 includes a fixed block 71 fixedly connected with the inner wall of the rack 1 and a movable block 72 slidingly installed on the roller 2, and the roller 2 penetrates the center of the fixed block 71. One side of the fixed block 71 is fixedly connected with a plurality of connecting rods 73, one end of the connecting rod 73 penetrates the movable block 72 and is fixedly connected with the rack 1, the movable block 72 is also slidingly installed on the connecting rod 73, and two nuts 74 are threadedly arranged on the connecting rod 73, and the nuts 74 are located on both sides of the movable block 72.

[0037] The inner sides of the fixed block 71 and the movable block 72 are both provided with ring grooves 75, and the waterproof and breathable film is inserted into the ring grooves 75 at both ends. Two symmetrical grooves 76 are provided on the fixed block 71 and the movable block 72, and the grooves 76 are in communication with the ring grooves 75. The waterproof and breathable film passes through the ring groove 75 at one end and extends out of the groove 76 at the other end. The main function of the ring groove 75 is to fix the position of the waterproof and breathable film to prevent it from shifting or sliding during cutting. When the waterproof and breathable film is inserted into the ring groove 75 at both ends, its position is stably controlled, thereby ensuring the accuracy and consistency of cutting, and preventing it from entering the gap between the movable block 72 and the roller 2, thereby avoiding potential cutting errors and damage. Further, there is a certain distance between the surface of the waterproof and breathable film and the surface of the roller 2. When the cutter 5 cuts downward, it can ensure that the waterproof and breathable film is cut off. If the waterproof and breathable film is too close to the surface of the roller 2, it may be worn or scratched due to friction, affecting the quality and performance of the waterproof and breathable film. Maintaining a certain distance can avoid unnecessary damage.

[0038] In the equipment for cutting waterproof and breathable film, in order to adapt to waterproof and breathable film of different widths, it is important to adjust the distance between the fixed block 71 and the movable block 72, so it is necessary to adjust the distance between the fixed block 71 and the movable block 72, and when adjusting, the movable block 72 is slid to a suitable position, and the nuts 74 on the connecting rod 73 at both ends of the movable block 72 are tightened to clamp and fix the position of the movable block 72.

[0039] In specific use, according to the width of the waterproof and breathable film to be cut, first, the distance between the fixed block 71 and the movable block 72 is adjusted, the movable block 72 is slid to a suitable position, and then the nuts 74 on the connecting rod 73 at both ends of the movable block 72 are tightened to clamp and fix the position of the movable block 72. The waterproof and breathable film is passed through the guide roller 4, and then one end is inserted from the slot 76 on one side of the fixed block 71 and the movable block 72, passes through the ring groove 75, and then is inserted from the slot 76 on the other side. According to the required cutting width of the waterproof and breathable film, the length of the distance adjusting cylinder 6 is adjusted. When the inner cylinder 62 is inserted into the outer cylinder 61, the inclined surface of the connecting block 623 is in contact with the inner wall of the outer cylinder 61 and is pressed to retract into the limiting groove 621, and the elastic block 622 is deformed. With the continuous sliding of the inner cylinder 62, when the connecting block 623 is aligned with the sliding groove 613, the elastic block 622 pushes the connecting block 623 to slide upward by using the restoring force, so that the top of the connecting block 623 extends out of the limiting groove 621 and is clamped in the groove 612, thereby locking the relative position of the inner cylinder 62 and the outer cylinder 61. In this process, the connecting block 623 also pushes the sliding block 611 upward, and the limiting block 6111 slides in the sliding groove 613. If the initially locked position meets the requirements, the exposed part of the connecting block 623 is pressed downward, the connecting block 623 is released from the groove 612, the inner cylinder 62 is continuously slid inward, and when the inner cylinder 62 is slid to the required position and successfully locked, the length of the distance adjusting cylinder 6 is determined, and the distance between the adjacent cutters 5 is also determined. The motor is started to drive the connecting rod 3 to slide vertically, so that the cutters 5 gradually approach the roller 2 and cut the waterproof and breathable film. After cutting is completed, the power is turned off.

[0040] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model has been disclosed as above with a preferred embodiment, it is not intended to limit the utility model. Any person skilled in the art can make some changes or modifications to the above-mentioned technical content without departing from the technical solution of the utility model, and any equivalent embodiment with equivalent changes and modifications is still within the scope of the utility model.
