A forward / reverse switch allows the second rotating shaft to rotate in both directions, moving the threaded sleeve. Guide wheels on both sides of the square rod roll against the inner wall of the strip-shaped hole, enabling horizontal movement of the square rod. This allows the square rod to drive the cutting disc horizontally, slitting the waterproof membrane.

Description

Technical Field

[0001] This utility model relates to the field of slitting device technology, and in particular to a waterproof membrane processing and slitting device. Background Technology

[0002] Waterproof membrane is a building material used to prevent moisture penetration and protect structures. It is widely used in construction, transportation, water conservancy, and other fields. Waterproof membranes typically consist of a substrate, a waterproof layer, and a protective layer, and possess excellent waterproof performance, durability, and ease of construction.

[0003] A search revealed that existing Chinese patent publication number "CN220241682U" provides an adjustable slitting device for processing waterproof membrane rolls. This device includes a slitting frame, a slitting roller fixedly connected to the inner wall of the frame, and two adjusting grooves on the side wall of the slitting roller. A double-ended screw is rotatably connected within each adjusting groove, and nuts are threaded onto both threaded sections of the double-ended screw. The nuts are slidably connected to the inner wall of the adjusting grooves, and a slitting blade is fixedly connected to the upper end of each nut. Adjusting rods are rotatably connected to both ends of the slitting roller, and these rods are fixedly connected to the connected double-ended screw. This invention, by setting up a double-ended screw, adjusting rods, and nuts, allows the double-ended screw to rotate by rotating the outer adjusting rod, thus adjusting the distance between the nuts and consequently the spacing of the slitting blades. This enables the cutting of waterproof membrane rolls of different widths without the need to change the cutting blade, making it very convenient to use.

[0004] Currently, the slitting of waterproof membranes is mainly carried out in the processing workshop, which is a processing step in the production process. After the waterproof membrane is rolled up to a certain extent, it is cut by slitting equipment to form a roll of waterproof membrane product. When laying it on the construction site, the waterproof membrane also needs to be slitted. However, because some waterproof membranes are thick and of high material quality, it is not only time-consuming and labor-intensive to cut them using conventional pliers, but it also results in uneven cut surfaces.

[0005] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a waterproof membrane processing and slitting device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a waterproof roll material processing and cutting device, including a base, the base having a U-shaped structure, a notch at the lower end of the base in a horizontal position, and a strip hole penetrating the interior of the base.

[0011] In detail, the upper end of the square rod is provided with a threaded sleeve, the threaded rod and the threaded sleeve are connected through each other, and the outer wall surface of the threaded rod and the inner wall surface of the threaded sleeve are threaded together.

[0012] In detail, a motor is provided at the end of the threaded rod away from the bearing seat, and a rotating shaft is provided inside the motor for driving. The end of the rotating shaft is fixedly connected to the end face of the threaded rod through a coupling.

[0013] In detail, a baffle is provided on the lower end of the inner side of the base. The lower end of the baffle is welded to the surface of the base, and the baffle is symmetrically distributed along the notch.

[0014] In detail, a bearing is provided at the bottom of the base, and the upper end of the bearing is fixedly assembled to the surface of the base by screws. There are four bearings, which are symmetrically distributed in pairs at the bottom of the base.

[0017] The design scheme proposed in this utility model has the following beneficial effects in application:

[0018] 1. When it is necessary to cut the waterproof membrane to the required length on site, unfold the waterproof membrane and lay it through the base. Then, the waterproof membrane can be set flat by the baffle on the base. Turn on the power of motor one, and motor one can drive the rotating shaft one, so that the shaft rod can be linked to make the cutting disc rotate. Thus, the waterproof membrane can be cut by moving the cutting disc.

[0019] 2.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference 1- Figure 4 A waterproof roll material processing and slitting device includes a base 1, which has a U-shaped structure. A notch 11 is provided at the lower horizontal position of the base 1. The notch 11 has a strip-shaped structure. A strip-shaped hole 12 is provided through the base 1.

[0027] A square rod 13 is provided inside the strip-shaped hole 12. Guide wheels 14 are provided on both sides of the square rod 13. The guide wheels 14 are fixedly installed on the surface of the square rod 13 through wheel frames. The inner wall of the strip-shaped hole 12 is rolled tightly against the concave area of ​​the guide wheel 14. Through the rolling contact of the guide wheel 14 with the inner wall of the strip-shaped hole 12, an auxiliary movement and positioning effect of the square rod 13 can be achieved, so that the square rod 13 can move horizontally. A connecting plate 15 is provided at the lower end of the square rod 13. The connection position of the connecting plate 15 and the square rod 13 is fixed by welding.

[0028] A bearing seat 16 is provided at the lower end of the connecting plate 15. The outer ring wall of the bearing seat 16 is fixedly assembled to the surface of the connecting plate 15 through a bracket. A shaft 17 is rotatably provided inside the bearing seat 16. A cutting disc 19 is provided on the surface of the shaft 17. The connection position between the cutting disc 19 and the shaft 17 is fixed by screws. The cutting disc 19 is located inside the notch 11. A motor 18 is provided at the other end of the shaft 17. The outer wall of the motor 18 is fixed to the surface of the connecting plate 15 through a bracket. A drive shaft 1 is provided inside the motor 18. The end of the drive shaft 1 is fixedly connected to the end of the shaft 17 through a coupling. When the power supply of the motor 18 is turned on, it can drive the drive shaft 1, thereby making the shaft 17 linked, and thus realizing the stable rotation of the cutting disc 19.

[0029] A bearing seat 2 is provided above the base 1. The outer ring wall of the bearing seat 2 is fixedly installed to the end of the base 1 by a bracket. A threaded rod 21 is rotatably provided inside the bearing seat 2. The threaded rod 21 is located directly above the strip hole 12. The bearing seat 2 can ensure the stable support of the end of the threaded rod 21.

[0030] A threaded sleeve 22 is provided at the upper end of the square rod 13. The outer ring wall of the threaded sleeve 22 is fixed to the square rod 13 by screws. The threaded rod 21 and the threaded sleeve 22 are connected through each other. The outer wall surface of the threaded rod 21 and the inner wall surface of the threaded sleeve 22 are threaded together. The threaded rod 21 is driven to make the threaded sleeve 22 movable. The guide wheels 14 distributed on both sides roll in contact with the inner wall of the strip hole 12, which can limit the square rod 13. Thus, the square rod 13 can move horizontally. In addition, when the cutting disc 19 is working, it can achieve stable horizontal movement.

[0031] A motor 23 is installed at the end of the threaded rod 21 away from the bearing 2. The outer wall of the motor 23 is fixedly mounted to the surface of the base 1 through a bracket. The motor 23 has a rotating shaft 2 for driving inside. The end of the rotating shaft 2 is fixedly connected to the end face of the threaded rod 21 through a coupling. The motor 23 is a servo motor and is externally connected to a forward and reverse switch through a wire. The model of the forward and reverse switch is HY2-8.

[0032] A baffle 3 is provided on the lower end of the inner side of the base 1. The lower end of the baffle 3 is welded to the surface of the base 1. The baffle 3 is symmetrically distributed along the notch 11. The upper end of the baffle 3 is horizontally positioned much lower than the lower end of the shaft seat 16 and the lower end of the motor 18 to avoid obstructing the movement of the shaft seat 16 and the motor 18. When the waterproof membrane passes through the base 1, the baffle 3 can be used to firmly position one side of it, thereby ensuring that the cutting is horizontal and neat.

[0033] Bearing 4 is provided at the bottom of the base 1. The upper end of the bearing 4 is fixedly assembled to the surface of the base 1 by screws. There are four bearings 4, which are symmetrically distributed in pairs at the bottom of the base 1.

[0034] A positioning shaft 41 is provided through the inside of the bearing 4. The surface of the positioning shaft 41 is interference-fitted with the inner ring wall of the bearing 4. The positioning shaft 41 can rotate relative to the bearing 4, which can play a universal adjustment effect when the wheel 43 moves.

[0035] The lower end of the positioning shaft 41 is provided with a connecting plate 42. The connection position of the connecting plate 42 and the positioning shaft 41 is fixed by welding. The lower end of the connecting plate 42 is provided with a wheel 43. The wheel 43 is fixedly assembled to the surface of the connecting plate 42 through a wheel frame. The wheel 43 can facilitate the movement of the overall structure during construction. When cutting, the worker can support the base 1 to ensure that the overall structure does not move. Flexible operation can be carried out according to the actual situation.

[0036] Working method: When the integral structure is used on the construction site, the rotation of the wheel 43 allows the integral structure to move to any position, and the rotation of the positioning shaft 41 relative to the bearing 4 facilitates the omnidirectional movement of the integral structure.

[0037] When on-site cutting of waterproof membrane for use requires length, the waterproof membrane is unfolded and laid through the base 1. Then, the waterproof membrane is flush with the baffle 3 on the base 1. The power of motor 18 is turned on, and motor 18 drives the rotating shaft 1, which in turn drives the shaft 17, causing the cutting disc 19 to rotate. Thus, the waterproof membrane can be cut by moving the cutting disc 19.

[0038] When the cutting disc 19 needs to be moved horizontally, the power supply of motor 23 is turned on, and the forward and reverse switch is used to make the rotating shaft 2 rotate in both directions, thereby allowing the threaded sleeve 22 to move. Through the guide wheels 14 on both sides of the square rod 13 rolling contact with the inner wall of the strip hole 12, the square rod 13 can be moved horizontally. In turn, the square rod 13 can drive the cutting disc 19 to move horizontally and cut the waterproof membrane.
