Description

Technical Field

[0001] This application relates to the field of construction tools technology, and more specifically, to a waterproof membrane cutting device. Background Technology

[0002] During construction, waterproof membranes are typically used to waterproof areas. These membranes need to be cut at the construction site or during the preparation phase. However, existing cutting devices can only produce waterproof membranes of fixed widths. This width may not be suitable for all surfaces. For example, if the membrane is too narrow, multiple membranes need to be spliced ​​together, increasing the risk of leakage and reducing construction efficiency. If the membrane is too wide, excess membrane needs to be cut again or extended to areas without waterproofing requirements, ultimately leading to material waste. Therefore, existing cutting devices have low applicability and poor flexibility. Utility Model Content

[0024] In this application, the waterproof membrane cutting device includes a roll mechanism, a cutting structure, and a segmentation mechanism arranged sequentially in a first direction.

[0042] Please refer to Figures 1 to 4 This application provides a waterproof roll material cutting device, including a roll mechanism, a cutting mechanism and a dividing mechanism arranged sequentially along a first direction D1;

[0043] A reel mechanism for installing waterproof membrane 00;

[0044] The dividing mechanism includes a lifting member 220, a cutter 230, a locking member 240, and a crossbeam frame 212 extending along the second direction D2. The lifting member 220 is connected to the end of the crossbeam frame 212 along the second direction D2 and is used to drive the crossbeam frame 212 to move along the third direction D3. The cutter 230 and the crossbeam frame 212 are slidably connected in the second direction D2. The locking member 240 is connected to the cutter 230 and is used to lock the position of the cutter 230 on the crossbeam frame 212 along the second direction D2.

[0045] The cutting mechanism includes a placement plate 320, a blade body 330, and a first driving member 340. The placement plate 320 and the blade body 330 are arranged opposite each other along a third direction D3. The first driving member 340 is connected to the blade body 330 and is used to drive the blade body 330 to move along the third direction D3 towards the placement plate 320 to cut the waterproof membrane 00 located between the placement plate 320 and the blade body 330.

[0046] The first direction D1, the second direction D2, and the third direction D3 are all perpendicular to each other.

[0047] In specific implementation, the second driving component 110 can be electrically driven or manually driven. For a specific implementation of a manually driven method, see [link to relevant documentation]. Figure 1 The second driving component 110 can be a rocker structure with an eccentric wheel structure.

[0048] In this embodiment, the waterproof membrane 00 cutting device includes a roll mechanism, a cutting structure, and a segmentation mechanism arranged sequentially in the first direction D1. After the waterproof membrane 00 is rolled out from the roll mechanism, it passes through the space between the placement plate 320 and the blade body 330, and is then segmented by the cutter 230. The segmentation mechanism includes a lifting member 220, a cutter 230, a locking member 240, and a crossbeam frame 212 extending along the second direction D2. The cutter 230 is slidably connected to the crossbeam frame 212 in the second direction D2. The lifting member 220 is connected to the end of the crossbeam frame 212 along the second direction D2 and is used to drive the crossbeam frame 212 to move along the third direction D3. Thus, the lifting member 220 can drive the crossbeam frame 212 to move along the third direction D3, and the moving crossbeam frame 212 can drive the cutter 230 to move along the third direction D3, so that the cutter 230 can... The surface of the waterproof membrane 00 is contacted to achieve cutting of the waterproof membrane 00; in addition, the locking member 240 is connected to the cutter 230 to lock the position of the cutter 230 on the crossbeam 212 along the second direction D2. Thus, by sliding on the crossbeam 212, the cutter 230 can change its position in the second direction D2. At the same time, the locking member 240 can lock the position of the cutter 230 on the crossbeam 212, thereby ensuring that the cutter 230 will not move after sliding and changing its position, and ensuring that the width of the waterproof membrane 00 passing through the cutter 230 is consistent. The cutting mechanism includes a placement plate 320, a blade 330, and a first driving member 340. The placement plate 320 and the blade 330 are arranged opposite each other along a third direction D3. After the free end of the waterproof membrane 00 is rolled out from the roll roller, it passes through the space between the blade 330 and the placement plate 320. The first driving member 340 is connected to the blade 330 and can drive the blade 330 to move along the third direction D3 toward the placement plate 320. The waterproof membrane 00 located between the placement plate 320 and the blade 330 can be cut by the blade 330.

[0049] See Figure 2 and Figure 3 In some embodiments, a sliding block 250 is provided at the end of the cutter 230 away from its own blade, and a sliding groove 2121 extending along the second direction D2 is provided on the crossbeam frame 212. The sliding block 250 and the sliding groove 2121 are slidably connected.

[0050] In this embodiment, the sliding block 250 and the sliding groove 2121 are slidably connected, which can realize the sliding connection between the cutter 230 and the crossbeam frame 212 along the second direction D2. The sliding block 250 is directly connected to the sliding groove 2121, which avoids wear between the cutter 230 and the crossbeam frame 212 and improves the life of the cutter 230.

[0051] Figure 5 As shown Figure 3 A magnified view of section A in the image. See also... Figure 3 and Figure 5 In some embodiments, the locking member 240 includes a connecting rod 245, a locking rod 241, a spring 243, and a plurality of limiting grooves 244. The plurality of limiting grooves 244 are arranged along the second direction D2 on the crossbeam frame 212. The connecting rod 245 is fixedly connected to the sliding block 250 through the mounting part 251. The connecting rod 245 is located on the side of the crossbeam frame 212 away from the cutting mechanism along the first direction D1. The limiting grooves 244 are located on the side of the crossbeam frame 212 close to the connecting rod 245 along the first direction D1. The connecting rod 245 has a through hole. The locking rod 241 passes through the through hole and is slidably connected to the through hole.

[0052] One end of the locking rod 241 is provided with a locking part 2412, which is adapted to the limiting groove 244 and is used to be accommodated in the limiting groove 244 and to be in contact with the two side walls of the limiting groove 244 along the second direction D2; the middle part of the locking rod 241 is provided with an assembly part 2413, which is located between the locking part 2412 and the connecting rod 245.

[0053] Spring 243 is sleeved on locking rod 241, and the two ends of spring 243 abut against assembly part 2413 and connecting rod 245 respectively.

[0054] In this embodiment, when the locking member 240 locks the position of the cutter 230, the locking part 2412 is accommodated in the limiting groove 244 and is in contact with the two side walls of the limiting groove 244 along the second direction D2. The limiting groove 244 limits the locking part 2412 along the two side walls of the second direction D2, restricting the movement of the locking part 2412 along the second direction D2. Consequently, the movement of the locking rod 241 along the second direction D2 is restricted, and the connecting rod 245 cannot move along the second direction D2. The connecting rod 245 is connected to the cutter 230 through the mounting part 251 and the sliding block 250, thereby realizing the fixation of the position of the cutter 230 on the crossbeam frame 212 along the second direction D2.

[0055] When the position of the cutter 230 needs to be adjusted, the locking lever 241 is pulled away from the cutting mechanism along the first direction D1. The assembly part 2413 and the locking part 2412 move with the locking lever 241. One end of the spring 243, which abuts against the assembly part 2413, moves closer to the other end of the spring 243, and the spring 243 is compressed. At the same time, the locking part 2412 disengages from the limiting groove 244. The connecting rod 245, the locking lever 241, the sliding block 250, or the mounting part 251 are operated to move together along the second direction D2. Move on the crossbeam 212 until it reaches the desired position, release the locking lever 241, and the spring 243 has a tendency to return to its original state. One end of the spring 243 that abuts against the assembly part 2413 moves away from the other end of the spring 243. The spring 243 drives the assembly part 2413, the locking part 2412 and the locking lever 241 to move until the locking part 2412 engages in a new limiting groove 244. The limiting groove 244 limits the locking part 2412 along the two side walls of the second direction D2, thereby fixing the position of the cutter 230 on the crossbeam 212 along the second direction D2.

[0056] See Figure 5 In some embodiments, the other end of the locking lever 241 is provided with a handle 2411. When it is necessary to adjust the position of the cutter 230, the operator can hold the handle 2411 and pull the locking lever 241 to move it along the second direction D2, which facilitates the adjustment of the position of the cutter 230.

[0057] See Figure 1 In some embodiments, the roll mechanism includes two roll frames 120, a lead screw 130, a second drive member 110, a circular limiting block 140, and a circular clamping plate 150. The two roll frames 120 are arranged opposite each other along a second direction D2, and the waterproof membrane 00 is located between the two roll frames 120. Each roll frame 120 is screwed to a lead screw 130. Each second drive member 110 is connected to the first end of a lead screw 130 for driving the lead screw 130 to rotate. The second end of each lead screw 130 is connected to a circular limiting block 140, and the circular limiting block 140 is rotatably connected to the circular clamping plate 150. Along the axial direction of the lead screw 130, the circular clamping plate 150 is located on the side of the corresponding circular limiting block 140 away from the first end of the corresponding lead screw 130. The circular clamping plate 150 is used to abut against the end face of the waterproof membrane 00.

[0058] In this embodiment, the second driving member 110 can be manually driven or electrically driven. The second driving member 110 drives the lead screw 130 to rotate. The lead screw 130 is screwed to the roll frame 120. Therefore, the lead screw 130 will move along its own axis while rotating, thereby driving the circular limit block 140 and the circular clamping plate 150 to move until the circular clamping plate 150 abuts against the end face of the waterproof membrane 00. In this way, the two circular clamping plates 150 can apply a certain pressure to the waterproof membrane 00 from both ends, that is, the two circular clamping plates 150 can clamp the waterproof membrane 00. Because the circular clamping plate 150 is rotatably connected to the circular limiting block 140, when the free end of the waterproof membrane 00 is rolled out, the waterproof membrane 00 will rotate, which will also drive the circular clamping plate 150 to rotate. At the same time, the circular clamping plate 150 will not transmit its own rotation to the lead screw 130, thus preventing the lead screw 130 from rotating. Therefore, this embodiment can ensure reliable clamping of the waterproof membrane 00. The second driving member 110 drives the lead screw 130 to rotate in the opposite direction. While rotating, the lead screw 130 will move along its own axis, thereby driving the circular limiting block 140 and the circular clamping plate 150 to move until the circular clamping plate 150 disengages from the end face of the waterproof membrane 00. The waterproof membrane 00 can then be removed from the roll mechanism for easy replacement.

[0059] See Figures 1 to 4 In some embodiments, the cutting mechanism further includes a cutting frame 310, with the blade body 330 and the first driving member 340 mounted on the cutting frame 310; the dividing mechanism further includes two support frames 211 arranged opposite each other along the second direction D2, with a crossbeam frame 212 disposed between the two support frames 211, and both ends of the crossbeam frame 212 along the second direction D2 being slidably connected to the support frames 211 along the third direction D3, and the support frames 211 being able to guide the movement of the crossbeam frame 212 along the third direction D3; the roll frame 120, the cutting frame 310 and the support frames 211 are arranged sequentially along the third direction D3.

[0060] See Figure 2 and Figure 3 In some embodiments, the lifting member 220 includes a third driving member 222 and two threaded rods 221. The third driving member 222 is used to drive the threaded rods 221 to rotate. Each threaded rod 221 is rotatably connected to a corresponding support frame 211. The end of the crossbeam frame 212 is provided with a moving block, which is screwed to the threaded rod 221.

[0061] In specific implementation, the third drive component 222 can be electrically driven or manually driven. For a specific implementation method using manual drive, see [link to relevant documentation]. Figure 1 The third driving component 222 can be a rocker structure with an eccentric wheel structure.

[0062] See Figure 2 and Figure 4 In some embodiments, the first driving member 340 includes a telescopic member 350 capable of extending or shortening along a third direction D3. The telescopic member 350 is mounted on the cutting frame 310, and the telescopic end of the telescopic member 350 is connected to the blade body 330. Specifically, the telescopic member 350 can be a hydraulic telescopic cylinder or a pneumatic telescopic cylinder. As a feasible approach in this embodiment, the telescopic member 350 can be a wirelessly remote-controlled pneumatic solenoid valve cylinder. Thus, when it is necessary to cut the waterproof membrane 00, the user can activate the wirelessly remote-controlled pneumatic solenoid valve cylinder to complete the cutting action of the waterproof membrane 00, achieving automatic control of the cutting mechanism.

[0063] See Figure 2 and Figure 4 In some embodiments, the cutting frame 310 has a guide hole extending along the third direction D3, and the blade body 330 is connected to the guide rod 360, which slides through the guide hole. Thus, the guide hole and the guide rod 360 can guide the movement of the blade body 330 along the third direction D3, reducing the probability of deflection when the blade body 330 moves along the third direction D3 and improving the reliability of the connection between the blade body 330 and the cutting frame 310.

[0064] See Figure 1 and Figure 2 In some embodiments, the waterproof membrane cutting device further includes a bracket 400, to which the roll frame 120, cutting frame 310, and support frame 211 are fixedly connected. The bracket 400 ensures that the positions of the roll frame 120, cutting frame 310, and support frame 211 in the first direction D1 remain fixed. This facilitates the installation and fixation of the waterproof membrane cutting device.

[0065] See Figure 3 The number of cutters 230 can be one or more. The more cutters 230 there are, the more segments the waterproof membrane 00 will be cut into in the width direction. Specifically, the number of segments the waterproof membrane 00 will be cut into is equal to the number of cutters 230 plus one. In specific implementations, the number of cutters 230 should be increased according to actual needs. This embodiment does not specifically limit the number of cutters 230.
