Description

Technical Field

[0001] This utility model relates to the technical field of glass fiber cloth production equipment, specifically to a cutting device. Background Art

[0002] Fiberglass cloth is a material widely used in construction engineering. During the processing of fiberglass cloth, it needs to be cut. The existing cutting method is to cut the fiberglass cloth with a hand-held cutting blade. The smooth fiberglass cloth is prone to deviation on the cutting table and is prone to curling, resulting in unstable cutting direction and affecting the quality of the final cut. Utility Model Content

[0003] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a cutting device that can prevent fiberglass cloth from slipping and curling during cutting, thereby improving the quality of the cut product.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a cutting device, comprising:

[0005] Cutting stand;

[0006] A cutting rack is mounted on the top surface of the cutting stand;

[0007] An adjustment groove is provided on the cutting rack.

[0008] The cutting blade is movably set in the adjustment groove via a lead screw and nut assembly;

[0009] The pressure roller assembly consists of two components, which are symmetrically arranged on both sides of the cutting blade.

[0010] The cutting groove is set on the cutting seat, and the position of the cutting blade corresponds vertically to the position of the cutting groove;

[0011] The cutting blade includes a push cylinder mounted on the lead screw and nut assembly, a blade holder mounted on the piston rod of the push cylinder, a rotary motor embedded in the blade holder, and a cutting disc mounted on the output shaft of the rotary motor.

[0012] The clamping wheel assembly includes a wheel seat set on the side wall of the tool holder. An inverted U-shaped clamping wheel seat is connected to the bottom surface of the wheel seat by multiple buffer springs. Multiple clamping wheels are arranged side by side at intervals in the U-shaped opening of the inverted U-shaped clamping wheel seat.

[0013] Preferably, the lead screw and nut assembly includes a lead screw disposed on the top surface of the cutting seat and a nut that is threadedly engaged with the lead screw. The cutting seat is also provided with a drive motor for driving the lead screw to rotate. Guide rails are arranged parallel to each other on both sides of the lead screw. A push cylinder is disposed on the nut. The length direction of the cutting groove is the same as the length direction of the axis of the lead screw in the lead screw and nut assembly, which facilitates the lead screw and nut assembly to drive the push cylinder to move, so that the cutting operation of the glass fiber cloth can be completed by the cutting knife.

[0014] Preferably, the distance from the pressing wheel to the top surface of the cutting seat is less than the distance from the cutting disc to the top surface of the cutting seat, so that the pressing wheel can press onto the fiberglass cloth before cutting, thereby preventing unevenness of the fiberglass cloth during cutting.

[0015] Preferably, the cutting seat is further provided with a pressure plate assembly, the pressure plate assembly comprising:

[0016] Left guide plate;

[0017] The right guide plate, left guide plate and right guide plate are respectively set vertically at both ends of the length direction of the adjustment groove;

[0018] There are two pressure plates, which are set in parallel and spaced between the left guide plate and the right guide plate. The two ends of the pressure plates in the length direction contact the side walls of the left guide plate and the right guide plate, respectively, and the two pressure plates are located on opposite sides of the tool holder.

[0019] There are two slides, and the length direction of the slides is the same as the length direction of the adjustment groove. There is one slide on each of the two pressure plates.

[0020] There are two pressure rod assemblies, which are respectively set on the two opposite side walls of the cutter holder. The two pressure rod assemblies correspond one-to-one with the positions of the two slide grooves. The end of the pressure rod assembly away from the cutter holder moves through the corresponding slide groove, so that the fiberglass cloth placed on the cutting seat can be pressed by the pressure rod assembly before cutting.

[0021] Preferably, the bottom surface of the pressure plate is parallel to the top surface of the cutting seat, which helps to improve the flatness of the glass fiber cloth after it is pressed.

[0022] Preferably, the pressure bar assembly includes:

[0023] There are two pressure rods, which are set parallel to each other on the side wall of the cutter holder. The end of the pressure rod away from the cutter holder moves through the corresponding groove, and the end of the pressure rod away from the cutter holder is rotatably set in the groove. This makes it easy to press the fiberglass cloth placed on the cutting seat with the pressure rod assembly, and also ensures that when the cutting knife moves under the drive of the lead screw and nut assembly to cut the fiberglass cloth, it will not drive the pressure rod assembly to move.

[0024] The beneficial effects of this utility model are as follows: Before cutting the fiberglass cloth, the entire fiberglass cloth can be pressed down by the pressure rod in the pressure plate assembly, which helps to keep the fiberglass cloth flat and prevents it from sliding; at the same time, when using the cutting disc to cut the fiberglass cloth, the pressure roller can press onto the fiberglass cloth and can move simultaneously with the cutting disc during cutting, so that the pressure roller always keeps in contact with the fiberglass cloth, thereby preventing the fiberglass cloth from curling up during cutting and improving the quality after cutting.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example 1

[0034] like Figures 1 to 5 As shown, this utility model provides a cutting device, including a cutting seat 1; a cutting frame 2 is disposed on the top surface of the cutting seat 1; an adjusting groove 3 is disposed on the cutting frame 2; a cutting blade 4 is movably disposed in the adjusting groove 3 via a lead screw and nut assembly 5; two pressing wheel assemblies 6 are provided, and the two pressing wheel assemblies 6 are symmetrically disposed on both sides of the cutting blade 4; a cutting groove 8 is disposed on the cutting seat 1, and the position of the cutting blade 4 corresponds vertically to the position of the cutting groove 8; the cutting blade 4 includes a push cylinder 41 disposed on the lead screw and nut assembly 5, a blade holder 42 is disposed on the piston rod of the push cylinder 41, a rotary motor 43 is embedded in the blade holder 42, and a cutting disc 44 is disposed on the output shaft of the rotary motor 43; the pressing wheel assembly 6 includes a wheel seat 61 disposed on the side wall of the blade seat 42, and an inverted U-shaped pressing wheel seat 63 is connected to the bottom surface of the wheel seat 61 by multiple buffer springs 62, and multiple pressing wheels 64 are arranged side by side at intervals in the U-shaped opening of the inverted U-shaped pressing wheel seat 63.

[0035] Before cutting, the fiberglass cloth is laid flat on the top surface of the cutting stand 1. The screw and nut assembly 5 drives the push cylinder 41 to move (simultaneously moving the blade holder 42, the rotary motor 43, and the pressure roller assembly 6). Once the desired cutting position is reached, the push cylinder 41 pushes the blade holder 42 and the rotary motor 43 towards the fiberglass cloth. The pressure roller 64 in the pressure roller assembly 6 first comes into contact with the fiberglass cloth, thus pressing it down. As the push cylinder 41 moves, it compresses the buffer spring 62. This ensures that the pressure roller 64 remains in contact with the fiberglass cloth during the cutting process. Until the cutting blade 4 comes into contact with the fiberglass cloth, the rotating motor 43 drives the cutting disc 44 to rotate, which cuts the fiberglass cloth. (At the same time, the lead screw and nut assembly 5 drives the push cylinder 41 to move. During cutting, the cutting disc 44 can move in the cutting groove 8, and the pressure roller 64 can roll on the fiberglass cloth. This helps to keep the pressure roller 64 in contact with the fiberglass cloth, avoiding the fiberglass cloth from lifting up during cutting, and finally completing the cutting operation of the fiberglass cloth.)

[0036] The distance between the pressure roller 64 and the top surface of the cutting seat 1 is less than the distance between the cutting disc 44 and the top surface of the cutting seat 1. This allows the pressure roller 64 to press onto the fiberglass cloth before cutting, thus preventing unevenness of the fiberglass cloth during cutting.

[0037] Example 2

[0038] Based on Example 1, such as Figure 1 , Figures 3 to 4 As shown, the lead screw and nut assembly 5 includes a lead screw mounted on the top surface of the cutting seat 1 and a nut threadedly engaged with the lead screw. The cutting seat 1 is also equipped with a drive motor for driving the lead screw to rotate. Guide rails are arranged parallel to each other on both sides of the lead screw. The push cylinder 41 is mounted on the nut. The length direction of the cutting groove 8 is the same as the length direction of the axis of the lead screw in the lead screw and nut assembly 5. (The lead screw and nut assembly 5 is prior art, so it will not be described in detail here.) The lead screw and nut assembly 5 can drive the push cylinder 41 and the knife holder 42 to move linearly, thereby causing the cutting knife 4 to move in the cutting groove 8 to complete the cutting operation of the glass fiber cloth.

[0039] Example 3

[0040] Based on Example 1, such as Figures 1 to 5 As shown, the cutting seat 1 is also equipped with a pressure plate assembly 7, which includes a left guide plate 71; the left guide plate 71 and the right guide plate 72 are respectively vertically arranged at both ends of the length direction of the adjusting groove 3; two pressure plates 73 are provided, which are arranged parallel and spaced between the left guide plate 71 and the right guide plate 72, and the two ends of the length direction of the pressure plates 73 are respectively in contact with the side walls of the left guide plate 71 and the right guide plate 72, and the two pressure plates 73 are respectively located on opposite sides of the cutter holder 42; two slide grooves 74 are provided, the length direction of the slide grooves 74 is the same as the length direction of the adjusting groove 3, and each of the two pressure plates 73 is provided with a slide groove 74; pressure rod There are two pressure rod groups 75, which are respectively set on the opposite side walls of the cutter holder 42, and the two pressure rod groups 75 correspond one-to-one with the positions of the two slide grooves 74. The end of the pressure rod group 75 away from the cutter holder 42 moves through the slide groove 74 at the corresponding position. The bottom surface of the pressure plate 73 is parallel to the top surface of the cutting seat 1. The pressure rod group 75 includes pressure rods 751, and there are two pressure rods 751. The two pressure rods 751 are set parallel and spaced apart on the side wall of the cutter holder 42. The end of the pressure rod 751 away from the cutter holder 42 moves through the slide groove 74 at the corresponding position, and the end of the pressure rod 751 away from the cutter holder 42 is rotatably set in the slide groove 74.

[0041] When the push cylinder 41 is activated to push the cutter holder 42 toward the fiberglass cloth, it simultaneously drives the two pressure plates 73 to move toward the fiberglass cloth (under the action of the pressure rod 751, the pressure rod 751 can press down on the pressure plate 73) until the bottom surface of the pressure plate 73 presses against the fiberglass cloth placed on the top surface of the cutting seat 1. Then the push cylinder 41 is stopped, and the lead screw and nut assembly 5 is activated to drive the push cylinder 41 and the cutter holder 42 to move linearly, so that the cutting knife 4 moves in the cutting groove 8 to complete the cutting operation of the fiberglass cloth. At this time, the ends of the two pressure rods 751 away from the cutter holder 42 roll in the corresponding sliding grooves 74. Under the action of the pressure rods 751, the bottom surface of the pressure plate 73 is kept in contact with the fiberglass cloth, and the cutting knife 4 moves in the cutting groove 8 to perform the cutting operation.

[0042] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
