Description

Technical Field

[0001] This utility model relates to the field of fixed-distance cutting technology, specifically a fixed-distance cutting device for building waterproof membrane. Background Technology

[0002] Building waterproof membrane is a thin film material that blocks moisture and protects buildings from water erosion. It is widely used in roof waterproofing, basement waterproofing, bathroom waterproofing, and other applications, effectively preventing water from penetrating the building's interior and protecting its structure and lifespan. Before application, the waterproof membrane needs to be cut to the required size for use on the building surface. Currently, waterproof membrane cutting is usually done manually by measuring the dimensions, resulting in low cutting accuracy and low efficiency due to the need for manual measurement before each cut. To improve this situation, a building waterproof membrane fixed-distance cutting device is proposed.

[0003] For example, the building waterproof membrane fixed-distance cutting device disclosed in the authorization announcement number CN222757621U includes a worktable, a storage roller is installed at one end of the worktable, a pull-up assembly is installed at the other end of the worktable, a moving assembly and several auxiliary rollers are installed on the worktable, a locking assembly is installed on the pull-up assembly, and a cutting assembly is installed on the moving assembly.

[0004] Although it achieves the goal of fixing the waterproof membrane to the pull-up component through the locking component, driving the pull-up component to pull the waterproof membrane to the required size, and then cutting it through the cutting component, the auxiliary component can move with the cutting component to assist the cutting of the waterproof membrane on both sides, so that it will not shift or tilt during cutting, thereby avoiding the problem of inaccurate cutting size caused by the movement of the waterproof membrane during cutting. It can meet the usage requirements and reduce the waste of waterproof membrane;

[0005] However, it does not solve the problem that the existing cutting device is not conducive to flexibly adjusting and adapting to cut waterproof membranes of different sizes, nor is it conducive to bidirectional fixed-distance cutting of waterproof membranes, thus affecting the convenience of fixed-distance cutting. Utility Model Content

[0006] The purpose of this utility model is to provide a fixed-distance cutting device for building waterproof membranes, so as to solve the problem mentioned in the background art that the cutting device is not convenient to flexibly adjust and adapt to cutting waterproof membranes of different sizes, which is not conducive to bidirectional fixed-distance cutting of waterproof membranes and affects the convenience of fixed-distance cutting.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fixed-distance cutting device for building waterproof membrane, comprising a cutting table and a support frame. The support frame is mounted on the top of the cutting table. A material placement roller is provided on the top of the cutting table on one side of the support frame. Integrated plates are symmetrically mounted on the side wall of the cutting table. Cylinders are symmetrically and movably mounted on the inner wall of the support frame. A push arm is mounted on the output end of each cylinder. An adjusting arm is provided on the inner wall of the support frame on one side of each cylinder. A hinge shaft is provided at the end of each adjusting arm near the support frame, and the adjusting arm is connected by a hinge. The connecting shaft is movably connected to the support frame. Each push arm is equipped with a linkage shaft at one end near the adjusting arm, and the push arm is movably connected to the adjusting arm through the linkage shaft. A cutting roller is installed between the two sets of adjusting arms. A bidirectional lead screw is movably installed inside the cutting roller. A servo motor is installed on the side wall of one set of adjusting arms, and the output end of the servo motor is connected to the bidirectional lead screw. Two sets of threaded sleeves are fitted on the surface of the bidirectional lead screw, and the threaded sleeves are threadedly connected to the bidirectional lead screw. A ring cutter is symmetrically slidably installed on the outside of the cutting roller, and the ring cutter is connected to the threaded sleeve.

[0008] Preferably, a stepper motor is provided on one side of the integrated board, and the stepper motor is fixedly connected to the integrated board.

[0009] Preferably, each of the stepper motors has a drive shaft at its output end, and a short connecting arm is fitted onto the surface of each drive shaft.

[0010] Preferably, each of the short connecting arms is provided with a long connecting arm at the end away from the drive shaft, and the long connecting arm is movably connected to the short connecting arm.

[0011] Preferably, each end of the long connecting arm away from the short connecting arm is provided with a movable rod, and the movable rod is movably connected to the long connecting arm.

[0012] Preferably, a limit block is provided on the other side of the integrated plate, and the moving rod is slidably connected to the limit block.

[0013] Preferably, a movable plate is provided above the cutting table, and the movable plate is connected to a movable rod, and a straight cutting blade is installed at the bottom of the movable plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the cutting device not only realizes flexible adjustment to adapt to cutting waterproof membranes of different sizes, facilitating bidirectional fixed-distance cutting of waterproof membranes, but also improves the convenience of fixed-distance cutting.

[0015] (1) Place the waterproof membrane roll on the feeding roller, and drive the feeding roller to rotate and unwind it, releasing the waterproof membrane and laying it flat on the cutting table. Because the waterproof membrane is relatively thick and has a large weight (refer to the commonly used Oriental Yuhong waterproof membrane), the feeding roller can move the waterproof membrane on the cutting table. When it is necessary to cut the waterproof membrane at a fixed distance, the servo motor drives the bidirectional lead screw to rotate, and the bidirectional lead screw drives the two sets of threaded sleeves to move towards or opposite each other. The threaded sleeves drive the annular cutter to slide on the surface of the cutting roller. The outer surface of the cutting roller is set with scales, and the size data can be obtained by reading the scales. The annular cutter moves to the corresponding scale. Then, the cylinder drives the push arm to move, and the push arm drives the adjusting arm to rotate around the hinge axis via the linkage shaft. The adjusting arm drives the cutting roller and the ring cutter to rotate, so that the ring cutter contacts the waterproof membrane. Under the continuous movement of the waterproof membrane, the waterproof membrane is cut laterally. The advantage of setting two sets of ring cutters is that the distance between the two sets of ring cutters can be adjusted to adapt to different cutting sizes. For example, it can cut three sets of waterproof membranes of the same size, two sets of the same size and one set of different size, or three sets of different sizes. This realizes flexible adjustment to adapt to cutting waterproof membranes of different sizes, which facilitates the lateral fixed-distance cutting of waterproof membranes.

[0016] (2) The waterproof membrane, which has been initially cut laterally, will continue to move under the continuous action of the feeding roller. When the waterproof membrane moves to the bottom of the moving plate, the stepper motor drives the drive shaft to rotate, the drive shaft drives the short connecting arm to rotate, and the short connecting arm drives the long connecting arm to swing back and forth. Under the sliding cooperation between the moving rod and the limiting block, the long connecting arm drives the moving rod to slide back and forth inside the limiting block. The moving rod drives the moving plate and the straight cutter to move up and down back and forth. The straight cutter cuts the waterproof membrane vertically. Since the frequency of the up and down reciprocating movement of the moving plate and the frequency of the movement of the waterproof membrane are rated, the length of each cut can be guaranteed to be consistent, so as to better cut the waterproof membrane at a fixed distance. This realizes the vertical fixed-distance cutting of the waterproof membrane and improves the convenience of fixed-distance cutting. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figure 1-5 This utility model provides an embodiment of a fixed-distance cutting device for building waterproof membrane, comprising a cutting table 1 and a support frame 3. The support frame 3 is installed at the top of the cutting table 1. A material placement roller 4 is provided at the top of the cutting table 1 on one side of the support frame 3. Integrated plates 2 are symmetrically installed on the side wall of the cutting table 1. Cylinders 9 are symmetrically and movably installed on the inner wall of the support frame 3, and the cylinders 9 provide power drive. Push arms 10 are installed at the output ends of the cylinders 9. Adjusting arms 6 are provided on the inner wall of the support frame 3 on one side of the cylinders 9. A hinge shaft 16 is provided at the end of the adjusting arm 6 near the support frame 3, and the adjusting arm 6 is movably connected to the support frame 3 through the hinge shaft 16. Each of the two sets of adjusting arms 6 is provided with a linkage shaft 11, and the push arm 10 is movably connected to the adjusting arm 6 through the linkage shaft 11. A cutting roller 5 is installed between the two sets of adjusting arms 6. A bidirectional lead screw 14 is movably installed inside the cutting roller 5. A servo motor 13 is installed on the side wall of one set of adjusting arms 6. The servo motor 13 plays the role of power drive, and the output end of the servo motor 13 is connected to the bidirectional lead screw 14. Two sets of threaded sleeves 15 are fitted on the surface of the bidirectional lead screw 14, and the threaded sleeves 15 are threadedly connected to the bidirectional lead screw 14. A ring cutter 12 is symmetrically slidably installed on the outside of the cutting roller 5, and the ring cutter 12 is connected to the threaded sleeve 15.

[0025] The waterproof membrane roll is placed on the feeding roller 4. An external motor drives the feeding roller 4 to rotate and unwind the roll, releasing the waterproof membrane flat onto the cutting table 1. Because the waterproof membrane is relatively thick and heavy (similar to commonly used waterproof membranes from Oriental Yuhong), the feeding roller 4 moves the membrane on the cutting table 1. When a fixed-distance cut is required, the servo motor 13 is activated, driving the bidirectional lead screw 14 to rotate. With the bidirectional lead screw 14 threadedly connected to the threaded sleeve 15, the bidirectional lead screw 14 drives two sets of threaded sleeves 15 to move towards or opposite each other. The threaded sleeves 15 then drive the annular cutter 12 to slide on the surface of the cutting roller 5. The outer surface of the cutting roller 5 is marked with graduations, allowing for the determination of dimensional data. After the cutter 12 moves to the corresponding scale, the cylinder 9 is opened, which drives the push arm 10 to move. The push arm 10 drives the adjusting arm 6 to rotate around the hinge shaft 16 via the linkage shaft 11. The adjusting arm 6 drives the cutting roller 5 and the annular cutter 12 to rotate, so that the annular cutter 12 contacts the waterproof membrane. Under the continuous movement of the waterproof membrane, the transverse cutting work of the waterproof membrane is completed. The advantage of setting two sets of annular cutters 12 is that the distance between the two sets of annular cutters 12 can be adjusted to adapt to different cutting sizes. For example, it can cut three sets of waterproof membranes of the same size, two sets of the same size and one set of different size, or three sets of different sizes. It realizes flexible adjustment to adapt to cutting waterproof membranes of different sizes, which facilitates transverse fixed-distance cutting of waterproof membranes.

[0026] Each side of the integrated board 2 is provided with a stepper motor 17, which serves as a power drive and is fixedly connected to the integrated board 2. Each output end of the stepper motor 17 is provided with a drive shaft 18, and each drive shaft 18 is fitted with a short connecting arm 22.

[0027] Each end of the short connecting arm 22 away from the drive shaft 18 is provided with a long connecting arm 19, and the long connecting arm 19 is movably connected to the short connecting arm 22. Each end of the long connecting arm 19 away from the short connecting arm 22 is provided with a moving rod 20, and the moving rod 20 is movably connected to the long connecting arm 19.

[0028] Limiting blocks 21 are provided on the other side of the integrated plate 2, and the moving rod 20 is slidably connected to the limiting block 21. A moving plate 7 is provided above the cutting table 1, and the moving plate 7 is connected to the moving rod 20. A straight cutting blade 8 is installed at the bottom of the moving plate 7.

[0029] The waterproof membrane, after initial horizontal cutting, continues to move under the continuous action of the feeding roller 4. When the waterproof membrane moves below the moving plate 7, the stepper motor 17 is turned on, which drives the drive shaft 18 to rotate. The drive shaft 18 drives the short connecting arm 22 to rotate, and the short connecting arm 22 drives the long connecting arm 19 to swing back and forth. With the sliding cooperation between the moving rod 20 and the limiting block 21, the long connecting arm 19 drives the moving rod 20 to slide back and forth inside the limiting block 21. The moving rod 20 drives the moving plate 7 and the straight cutter 8 to move up and down back and forth. The straight cutter 8 cuts the waterproof membrane vertically. Since the frequency of the up and down reciprocating movement of the moving plate 7 and the frequency of the waterproof membrane movement are rated, the length of each cut can be kept consistent, thus enabling better fixed-distance cutting of the waterproof membrane. This achieves vertical fixed-distance cutting of the waterproof membrane and improves the convenience of fixed-distance cutting.

[0030] Working principle: The waterproof membrane roll is placed on the feeding roller 4. An external motor drives the feeding roller 4 to rotate and unwind the roll, releasing the waterproof membrane and laying it flat on the cutting table 1. Because the waterproof membrane is relatively thick and heavy (similar to the commonly used Oriental Yuhong waterproof membrane), the feeding roller 4 can move the waterproof membrane on the cutting table 1. When it is necessary to cut the waterproof membrane at a fixed distance, the servo motor 13 drives the bidirectional lead screw 14 to rotate. The bidirectional lead screw 14 drives two sets of threaded sleeves 15 to move towards or opposite directions. 5 drives the annular cutter 12 to slide on the surface of the cutting roller 5. The outer surface of the cutting roller 5 is marked with graduations, and the size data can be obtained by reading the graduations. After the annular cutter 12 moves to the corresponding graduation, the cylinder 9 drives the push arm 10 to move. The push arm 10 drives the adjusting arm 6 to rotate around the hinge shaft 16 via the linkage shaft 11. The adjusting arm 6 drives the cutting roller 5 and the annular cutter 12 to rotate, so that the annular cutter 12 contacts the waterproof membrane. With the continuous movement of the waterproof membrane, the waterproof membrane is cut laterally. The advantage of setting two sets of annular cutters 12 is that the distance between the two sets of annular cutters 12 can be adjusted to adapt to different cutting sizes. For example, it can cut three sets of waterproof membranes of the same size, two sets of the same size and one set of different size, or three sets of different sizes. The waterproof membrane that has been initially cut horizontally will continue to move under the continuous action of the feeding roller 4. When the waterproof membrane moves to below the moving plate 7, the stepper motor 17 drives the drive shaft 18 to rotate, the drive shaft 18 drives the short connecting arm 22 to rotate, and the short connecting arm 22 drives the long connecting arm 19 to swing back and forth. Under the sliding cooperation between the moving rod 20 and the limiting block 21, the long connecting arm 19 drives the moving rod 20 to slide back and forth inside the limiting block 21. The moving rod 20 drives the moving plate 7 and the straight cutter 8 to move up and down back and forth. The straight cutter 8 cuts the waterproof membrane vertically. Since the frequency of the up and down reciprocating movement of the moving plate 7 and the frequency of the movement of the waterproof membrane are rated, the length of each cut can be kept consistent, thereby better cutting the waterproof membrane at a fixed distance.
