[0001] The present application relates to the technical field of waterproof coiled material preparation and cutting equipment, and in particular to a waterproof coiled material slitting device. Background Art

[0002] Waterproofing roll refers to a waterproofing material product made by impregnating asphalt or polymer waterproofing materials on the base. It is provided in the form of a roll and is called waterproofing roll. Waterproofing roll is mainly used in building walls, roofs, tunnels, roads, landfills, etc. It is a kind of flexible building material product that can be rolled into a roll to prevent external rainwater and groundwater leakage.

[0003] Sometimes, during the use of waterproofing membranes, it is necessary to cut the waterproofing membranes in half as required. The current cutting methods are either to manually measure and mark the center line before cutting manually, or to use a cutting machine for cutting. In the former, it is easy for workers to make errors during manual operation, and it is impossible to ensure that the cut seam always coincides with the center line during cutting, the cutting accuracy is not high, and it is easy to cause material waste; in the latter, the cutting machine also needs to find the center line of the waterproofing membrane before cutting, and the position of the cutting tool needs to be adjusted for waterproofing membranes of different sizes, which is time-consuming, labor-intensive, and complicated to operate. Summary of the invention

[0004] In order to solve the shortcomings of the above-mentioned prior art, the present application provides a waterproof roll material slitting device, which, while ensuring the cutting accuracy and cutting efficiency of the device, only requires one driving component to simultaneously complete the limiting and cutting work of the waterproof roll material, and can be suitable for slitting waterproof roll materials of different sizes, and is highly practical.

[0005] In order to achieve the above object, the present invention adopts the following technologies: A waterproofing coiled material slitting device, comprising a fixing plate, an upper end surface of which is provided with a through slot along its length direction, two limiting plates relatively movable along the length direction of the fixing plate are symmetrically arranged in the through slot, and are used to limit the two sides of the waterproofing coiled material, and the ends of the limiting plates facing away from each other are connected with a bent rod, and the bent rod comprises a horizontal section arranged parallel to the length direction of the fixing plate, one end of the horizontal section is connected to the limiting plate, and the other end of the horizontal section is connected to a vertical section parallel to the width direction of the fixing plate; Two vertical plates are symmetrically arranged at both ends of the fixed plate in the length direction, and a slide groove is provided on the vertical plate along the height direction of the fixed plate, a sliding plate is slidably installed in the slide groove, a guide hole is vertically provided at one end of the sliding plate, a guide rod is provided at one end in the slide groove corresponding to the guide hole, a first spring is sleeved on the guide rod, the first spring abuts between the bottom surface of the sliding plate and the bottom surface of the slide groove, an inclined hole is penetrated through the sliding plate along its width direction, an end of the inclined hole close to the fixed plate is higher than an end away from the fixed plate, the length of the inclined hole is adjustable, and a predetermined highest end of the inclined hole is vertically connected with the vertical hole, and the other end of the vertical section is slidably penetrated in the inclined hole; A movable frame is provided on one side of the length direction of the fixed plate and moves along the height direction of the fixed plate. Two push plates are symmetrically provided at the bottom of both ends of the movable frame. The push plates are used to act on the sliding plate when moving downward with the movable frame. A cutting knife assembly is installed on the side of the movable frame facing the through groove relative to the symmetrical center of the two limit plates. The cutting knife assembly is used to cut the waterproof membrane at the through groove and make the cut formed on the waterproof membrane parallel to the width direction of the fixed plate.

[0006] The beneficial effects of the present invention are: 1. The movement of the mobile frame can simultaneously realize the downward movement of the push plate and the cutting knife assembly. The downward movement of the push plate will push the sliding plate downward. First, the limit plate is closed to the middle through the sliding cooperation of the inclined hole and the bent rod to realize the limit of both sides of the waterproof membrane, and then the vertical hole and the bent rod are used to slide and cooperate to realize the downward half-cutting of the cutting knife assembly. The limit plate limits the waterproof membrane so that its middle part is aligned with the cutting knife assembly to automatically realize half-cutting. While ensuring cutting accuracy and cutting efficiency, the structure is simple and easy to operate.

[0007] 2. The adjustable length of the inclined hole can make the sliding cooperation between the inclined hole and the bent rod adjustable, that is, the displacement of the bent rod sliding from one end of the inclined hole to the other end can be adjusted, so that the relative distance between the two limit plates before entering the static state can be adjusted, so that the limit plates can adapt to the limitation of waterproof membranes of various sizes, thereby improving the practicality of the device.

DETAILED DESCRIPTION

[0016] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the implementation modes of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] The present application embodiment provides a waterproof coiled material slitting device, such as Figure 1-Figure 6 As shown, it includes a fixed plate 1, whose upper end surface is penetrated by a through groove 11 along its own length direction, and two limiting plates 2 that can move relatively along the length direction of the fixed plate 1 are symmetrically arranged in the through groove 11, which are used to limit the two sides of the waterproof membrane, and the ends of the limiting plates 2 that are away from each other are connected with a bent rod 21, and the bent rod 21 includes a horizontal section arranged parallel to the length direction of the fixed plate 1, one end of the horizontal section is connected to the limiting plate 2, and the other end of the horizontal section is connected to a vertical section parallel to the width direction of the fixed plate 1, that is, the bent rod 21 is arranged parallel to the fixed plate 1. In this embodiment, the bent rod 21 is consistent in height with the fixed plate 1.

[0018] Two vertical plates 3 are symmetrically provided at both ends of the fixed plate 1 in the length direction, and a slide groove 31 is provided on the vertical plate 3 along the height direction of the fixed plate 1, and a sliding plate 4 is slidably installed in the slide groove 31, and a guide hole 41 is vertically provided at one end of the sliding plate 4, and a guide rod 311 is provided at one end in the slide groove 31 corresponding to the guide hole 41, and a first spring 312 is sleeved on the guide rod 311, and the first spring 312 abuts between the bottom surface of the sliding plate 4 and the bottom surface of the slide groove 31, and an inclined hole 42 is provided through the sliding plate 4 along its width direction, and the end of the inclined hole 42 close to the fixed plate 1 is higher than the end away from the fixed plate 1, the length of the inclined hole 42 is adjustable, and the predetermined highest end of the inclined hole 42 is vertically connected with the vertical hole 43, and the other end of the vertical section is slidably penetrated into the inclined hole 42.

[0019] A movable frame 5 is provided on one side in the length direction of the fixed plate 1 and moves along the height direction of the fixed plate 1. Two push plates 53 are symmetrically provided at the bottom of both ends of the movable frame 5. The push plates 53 are used to act on the sliding plate 4 when moving downward with the movable frame 5. A cutting knife assembly 51 is installed on the side of the movable frame 5 facing the through groove 11 relative to the symmetric center of the two limit plates 2. The cutting knife assembly 51 is used to cut the waterproof membrane at the through groove 11 and make the slit formed on the waterproof membrane parallel to the width direction of the fixed plate 1.

[0020] When in use, the waterproof roll material to be cut is laid horizontally on the fixed plate 1. It can be laid directly manually, or a waterproof roll material unwinding device and a waterproof roll material rewinding device can be provided on opposite sides parallel to the length direction of the fixed plate 1, so as to facilitate continuous slitting of the waterproof roll material.

[0021] The movable frame 5 moves downward, and the downward movement of the movable frame 5 drives the two push plates 53 to move downward synchronously. The push plates 53 push the sliding plate 4 to move downward, and the first spring 312 continues to be compressed. The downward movement of the sliding plate 4 will cause the two limiting plates 2 to gradually converge toward the middle through the sliding cooperation between the bent rod 21 and the inclined hole 42, until the inner side surfaces of the limiting plates 2 are in contact with the two side surfaces of the waterproof membrane. Under the action of the limiting plates 2, the waterproof membrane is centered and limited on the upper surface of the fixed plate 1.

[0022] The moving frame 5 continues to move downward, and the downward movement of the moving frame 5 drives the cutting knife assembly 51 installed in the middle of the moving frame 5 to move downward synchronously, and the cutting knife assembly 51 starts to work. In this embodiment, the cutting knife assembly 51 cuts the waterproofing coiled material by rotating contact until the cutting knife assembly 51 extends into the through groove 11 and completely cuts the waterproofing coiled material at the through groove 11. In this process, the downward movement of the moving frame 5 will also drive the two push plates 53 to move downward synchronously, and the push plates 53 push the sliding plate 4 to move downward. The first spring 312 continues to be compressed, and the downward movement of the sliding plate 4 will enable the moving frame 5 to continue to move downward through the sliding cooperation between the bent rod 21 and the vertical hole 43, while the two limit plates 2 always remain fixed and limit the two sides of the waterproofing coiled material.

[0023] That is, when the curved rod 21 slides in the inclined hole 42, the two limit plates 2 are in a moving state and gradually converge toward the center, and the cutting knife assembly 51 moves downward synchronously with the moving frame 5 but still has a predetermined distance from the fixed plate 1. When the curved rod 21 slides in the vertical hole 43, the two limit plates 2 are stationary and have formed a state of centering the waterproofing membrane. The cutting knife assembly 51 gradually moves downward and cuts the waterproofing membrane at the through groove 11. Because the cutting knife assembly 51 is arranged relative to the symmetrical center of the two limit plates 2, the cutting knife assembly 51 can automatically cut the waterproofing membrane in half when cutting, avoiding the error influence when manually measuring the center line and then manually cutting.

[0024] The length of the inclined hole 42 is adjustable, that is, the displacement of the bent rod 21 sliding from one end of the inclined hole 42 to the other end is adjustable, so that the relative distance between the two limiting plates 2 before entering the static state is adjustable, so that the limiting plates 2 can adapt to the limiting of waterproof membranes of various sizes.

[0025] Specifically, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the sliding plate 4 includes a lower plate 44, the top surface of which is an inclined surface, and the inclined surface is inclined downward in a direction away from the fixed plate 1, and an inclined groove 441 is provided in parallel on the inclined surface. An upper plate 45 is provided on the top of the inclined surface to move along its own inclination direction, and a vertical hole 43 is provided at the bottom of the upper plate 45. The bottom surface of the upper plate 45 from the vertical hole 43 to the side away from the fixed plate 1 is in parallel contact with the inclined surface, and is used to form an inclined hole 42 with the inclined groove 441 when sliding, and the bottom surface of the upper plate 45 from the vertical hole 43 to the side close to the fixed plate 1 is in parallel contact with the bottom surface of the inclined groove 441, and is used to close the inclined hole 42. Before the moving frame 5 starts to move downward, the length of the inclined hole 42 formed by the upper plate 45 and the lower plate 44 is a predetermined maximum value, and the position of the upper plate 45 is the initial position at this time. The moving frame 5 starts to move downward, and the downward movement of the moving frame 5 drives the two push plates 53 to move downward synchronously. The push plates 53 push the sliding plate 4 to move downward, and the first spring 312 is compressed. The downward movement of the sliding plate 4 will cause the two limit plates 2 to gradually close to the middle through the sliding cooperation between the bent rod 21 and the inclined hole 42, until the inner side surfaces of the limit plates 2 are in contact with the two side surfaces of the waterproof roll. At this time, the upper plate 45 is moved to move the vertical hole 43 to the top of the end of the vertical section of the bent rod 21, shortening the length of the inclined hole 42, so that the bent rod 21 will no longer slide in the inclined hole 42 after the limit plate 2 completes the limit of the waterproof roll, but starts to slide in the vertical hole 43, so that the limit plate 2 remains stationary, and the moving frame 5 can continue to drive the cutting knife assembly 51 to move downward to complete the cutting of the waterproof roll.

[0026] Specifically, Figure 4As shown, when the length of the inclined hole 42 formed between the upper plate 45 and the lower plate 44 is the predetermined minimum value, the top of the vertical hole 43 is at the same height as the other end of the vertical section. Since the bent rod 21 is arranged parallel to the fixed plate 1 in this embodiment and its height is consistent with the fixed plate 1, the top of the vertical hole 43 is at the same height as the fixed plate 1. When the length of the inclined hole 42 formed between the upper plate 45 and the lower plate 44 is the predetermined minimum value, the upper plate 45 moves to the predetermined lowest position relative to the lower plate 44. Since the length of the vertical hole 43 remains unchanged, the top of the vertical hole 43 is also at the predetermined lowest point. It is necessary to ensure that the length of the vertical hole 43 is set so that the bent rod 21 will not interfere with the movement of the upper plate 45 under any circumstances, that is, when the upper plate 45 is at the predetermined lowest position, the vertical hole 43 can still smoothly slide and cooperate with the bent rod 21, so as to ensure that the cutting knife assembly 51 can continue to move downward until the cutting work is completed.

[0027] Specifically, Figure 4 and Figure 5 As shown, the lower plate 44 extends upward on both sides of the inclined surface to form blocking portions 442 for limiting the movement range of the upper plate 45 to prevent the other end of the inclined hole 42 formed between the upper plate 45 and the lower plate 44 from being unable to close.

[0028] Specifically, Figure 2 and Figure 4 As shown, a push rod 451 parallel to the inclined surface is connected to the side of the upper plate 45 away from the fixed plate 1, and the push rod 451 is driven to move by a cylinder 443. The cylinder 443 is fixedly mounted on the lower plate 44, and the output end of the cylinder 443 passes through the blocking portion 442 and is coaxially connected to the push rod 451. The cylinder 443 drives the push rod 451 to move to realize the movement of the upper plate 45 relative to the lower plate 44, thereby realizing the adjustment of the length of the inclined hole 42.

[0029] Specifically, Figure 1 and Figure 2 As shown, the middle thread of the movable frame 5 is passed through a screw rod 12, and the screw rod 12 is vertically and rotatably arranged on a first horizontal platform 6. The first horizontal platform 6 is arranged above the fixed plate 1 and has a predetermined distance from the fixed plate 1 to leave space for feeding or discharging the waterproof membrane when it is laid flat on the fixed plate 1. The screw rod 12 is driven to rotate by a motor 121, and the motor 121 is arranged on a second horizontal platform 7. The second horizontal platform 7 is arranged above the first horizontal platform 6.

[0030] Specifically, Figure 1-Figure 3 As shown, buffer rods 52 are symmetrically and vertically arranged at the bottom of both ends of the moving frame 5, and the push plate 53 is passed through the buffer rod 52 and is arranged to move vertically. A second spring 54 is sleeved on the buffer rod 52, and the second spring 54 is arranged between the moving frame 5 and the push plate 53, so as to provide a certain buffering capacity for the movement between the moving frame 5 and the sliding plate 4, thereby improving the stability of the device.

[0031] When applied, the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
