[0001] The utility model relates to the technical field of curtain cloth cutting, in particular to an electrostatic curtain cloth cutting device. Background Technique

[0002] Curtains are an indispensable part of home decoration, with the functions of shading, heat insulation and adjusting indoor light. The fabrics of curtain cloth mainly include cotton, linen, polyester, silk and other materials. During the curtain production process, it is necessary to cut the curtain fabric according to the required size, so a cutting device is needed.

[0003] The existing curtain cloth cutting device mainly consists of a cutting table, two groups of pressing components, a guiding mechanism and a cutting component. When cutting the curtain cloth, first place the curtain cloth to be cut on the cutting table, and then through the action of the pressing components, press and fix both ends of the curtain cloth. After both ends of the curtain cloth are pressed and fixed, start the pneumatic cylinder to make the cutting knife move vertically downward until the cutting knife moves vertically downward to contact the fabric surface, and then drive the cutting knife to move through the guiding mechanism, so as to be able to cut the curtain cloth by moving, and the purpose of cutting the curtain cloth is completed.

[0004] The existing curtain cloth cutting device only fixes the curtain cloth through two pressing plates, and its fixing range is relatively limited, and it may not be able to fully cover the entire cutting area, resulting in ineffective fixing of the curtain cloth, and it is easy for the curtain cloth to shift during the cutting process, resulting in uneven cutting edges, affecting the overall quality and aesthetics of the curtain; Therefore, an electrostatic curtain cloth cutting device is proposed for the above problems. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art and solve the problems raised in the above background technique, the utility model proposes an electrostatic curtain cloth cutting device.

[0006] The technical solution adopted by the present utility model to solve its technical problems is as follows: An electrostatic curtain cloth cutting device of the present utility model includes a cutting table. On one side of the top of the cutting table, a fixed frame is installed. On the other side of the top of the cutting table, a movable frame is installed. Screw holes are provided on both the fixed frame and the movable frame. A threaded rod is rotatably assembled in the screw holes. The bottom end of the threaded rod is rotatably installed with a pressing plate, and a rubber pad is fixedly connected to the bottom side of the pressing plate. The top of the threaded rod is fixedly connected with a rotating disk. Two rod holes are provided on both the fixed frame and the movable frame. A limiting rod is inserted through each of the two rod holes, and the two limiting rods are respectively located on both sides of the threaded rod. The bottom end of the limiting rod is fixedly connected to the pressing plate. Limiting sliding rails are fixedly connected to both side walls of the cutting table. Sliding seats are sleeved on both of the two limiting sliding rails. Connecting plates are fixedly connected to both of the two sliding seats, and the other end of the connecting plate is fixedly connected to the movable frame. Fixing plates are fixedly connected to one end of both of the two limiting sliding rails. A first pneumatic cylinder is installed on each of the two fixing plates. The acting end of the first pneumatic cylinder is assembled with a first pneumatic rod, and the other end of the first pneumatic rod is fixedly connected to the connecting plate. A plurality of air holes are provided on the cutting table. A cloth suction cover is fixedly connected to the bottom side of the cutting table. An installation frame is fixedly connected to the bottom side of the cloth suction cover. An air extraction pump is assembled on the installation frame. The input port of the air extraction pump is connected with an air extraction pipe, and the other end of the air extraction pipe is arranged inside the cloth suction cover. The output port of the air extraction pump is connected with an exhaust pipe. When fixing the curtain cloth, first, it is necessary to adjust the distance between the two pressing components according to the length of the curtain cloth. Start the first pneumatic cylinder, so that the first pneumatic rod drives the sliding seat to move along the limiting sliding rail, and then the movable frame drives the pressing plate to move accordingly. Until the movable frame moves to a suitable position, the first pneumatic cylinder stops working, so that the distance between the two pressing components can be adjusted according to requirements, which is convenient for subsequent pressing and fixing of curtain cloths of different lengths. After the distance between the two pressing components is adjusted, place the curtain cloth to be cut flat on the cutting table. Then rotate the rotating disk. With the cooperation of the limiting rod, the threaded rod drives the pressing plate to move vertically downward until the pressing plate moves down to contact the surface of the curtain cloth, so that the head and tail ends of the curtain cloth can be pressed and fixed. Then start the air extraction pump, so that the air extraction pipe extracts air from the cloth suction cover, generating a strong adsorption force at the air holes, and then making the cloth tightly adhere to the surface of the cutting table. Through the double fixation operations of the pressing mechanism and the adsorption mechanism, the cutting area of the curtain cloth can be fully covered, effectively pressing and fixing the curtain cloth, ensuring that the curtain cloth will not shift or slide during the cutting process, guaranteeing the neatness of the cutting edge, and greatly improving the quality and aesthetics of the curtain.

[0007] Preferably, two sliding grooves are formed in the cutting table. A scale marking is provided at the port of one of the sliding grooves. First lead screws are rotatably installed in both of the two sliding grooves. Two first motors are installed on one side wall of the cutting table. The output end of the first motor is connected to one end of the first lead screw. During the cutting process, the first motor is started to rotate the first lead screw, so that the moving plate drives the cutting mechanism to move, thereby enabling the cutting operation to be performed on different positions of the curtain fabric.

[0008] Preferably, moving plates are sleeved on both of the two first lead screws, and the bottom end of the moving plate is arranged in the sliding groove. A second motor is installed on one of the moving plates. The output end of the second motor is connected to a second lead screw. The other end of the second lead screw is rotatably installed on the other moving plate. A movable block is sleeved on the second lead screw. Two guide rods are fixedly connected between the two moving plates, and the two guide rods are respectively located on both sides of the second lead screw, and the guide rods penetrate through the movable block. A second pneumatic cylinder is installed on the bottom side of the movable block. The acting end of the second pneumatic cylinder is equipped with a second pneumatic rod. The bottom end of the second pneumatic rod is fixedly connected with a mounting plate. A cutting knife is assembled on the bottom side of the mounting plate. After the curtain fabric is fixed, when cutting, the second pneumatic cylinder is started to drive the second pneumatic rod to vertically move down until it contacts the surface of the fabric. At the same time, the second motor is started to rotate the second lead screw. With the cooperation of the guide rods, the movable block drives the cutting knife to move, thereby enabling the moving cutting operation to be performed to meet the cutting requirements of curtain fabrics of different widths. During the cutting process, the first motor is started to rotate the first lead screw, so that the moving plate drives the cutting mechanism to move, thereby enabling the cutting operation to be performed on different positions of the curtain fabric.

[0009] Preferably, two pipe holes are formed in the mounting plate. Movable rods are inserted in both of the two pipe holes, and the two movable rods are respectively located on both sides of the cutting knife. Anti-detachment caps are fixedly connected to the tops of the two movable rods. Fixed seats are fixedly connected to the bottoms of the two movable rods. Pressing rollers are rotatably installed in the fixed seats. Two springs are fixedly connected between the top side of the fixed seat and the mounting plate, and the two springs are correspondingly sleeved on the movable rods. During the cutting process, through the cooperation of the movable rods and the springs, the pressing rollers are always in contact with the fabric, so that the fabric on both sides of the cutting knife can be moved and pressed and fixed. The pressing rollers can move and press and fix in real time following the cutting knife, ensuring that the cutting area is always under a stable pressure, further preventing the curtain fabric from shifting or sliding during the cutting process. This real-time fixing method helps to maintain the accuracy of the cutting trajectory and improve the cutting accuracy.

[0010] The beneficial effects of the present utility model are as follows:

[0011] 1. When the utility model fixes the curtain fabric, first, it is necessary to adjust the distance between the two pressing components according to the length of the curtain fabric. Start the first pneumatic cylinder, so that the first pneumatic rod drives the sliding seat to move along the limit slide rail, and then the movable frame drives the pressing plate to move accordingly. Until the movable frame moves to a suitable position, the first pneumatic cylinder stops working. Thus, the distance between the two pressing components can be adjusted according to requirements, which is convenient for subsequent pressing and fixing of curtain fabrics of different lengths. After the distance adjustment of the two pressing components is completed, place the curtain fabric to be cut flat on the cutting table. Then rotate the rotary disk. With the cooperation of the limit rod, the threaded rod drives the pressing plate to move vertically downward until the pressing plate moves down to contact the surface of the curtain fabric. Thus, the head and tail ends of the curtain fabric can be pressed and fixed. Then start the air extraction pump, so that the air extraction pipe extracts air from the cloth suction cover, generating a strong adsorption force at the air permeable holes. Then the fabric is closely attached to the surface of the cutting table. Through the dual fixation operations of the pressing mechanism and the adsorption mechanism, the cutting area of the curtain fabric can be fully covered, effectively pressing and fixing the curtain fabric, ensuring that the curtain fabric will not shift or slide during the cutting process, guaranteeing the neatness of the cutting edge, and greatly improving the quality and aesthetics of the curtain;

[0012] 2. During the cutting process of the utility model, through the cooperation of the movable rod and the spring, the pressing roller is always in contact with the fabric, so that the fabric on both sides of the cutting knife can be moved and pressed and fixed. Through the pressing roller, it can move and press and fix in real time following the cutting knife, ensuring that the cutting area is always under a stable pressure, further preventing the curtain fabric from shifting or sliding during the cutting process. This real-time fixation method helps to maintain the accuracy of the cutting trajectory and improve the cutting accuracy. Brief Description of the Drawings

[0024] Working principle: As for the existing curtain cloth cutting device, only two pressing plates 5 are used to fix the curtain cloth, and its fixing range is relatively limited, which may not fully cover the entire cutting area, resulting in ineffective fixing of the curtain cloth. It is easy for the curtain cloth to shift during the cutting process, resulting in uneven cutting edges and affecting the overall quality and aesthetics of the curtain. Therefore, an electrostatic curtain cloth cutting device is proposed to address the above problems. When fixing the curtain cloth, first, the distance between the two pressing components needs to be adjusted according to the length of the curtain cloth. The first pneumatic cylinder 13 is started, and the first pneumatic rod 12 drives the sliding seat 9 to move along the limit slide rail 8, and then the movable frame 3 drives the pressing plate 5 to move accordingly. Until the movable frame 3 moves to a suitable position, the first pneumatic cylinder 13 stops operating, so that the distance between the two pressing components can be adjusted according to requirements, facilitating subsequent pressing and fixing of curtain cloths of different lengths. After the distance between the two pressing components is adjusted, the curtain cloth to be cut is placed flat on the cutting table 1. Then, the rotary disk 6 is rotated. With the cooperation of the limit rod 7, the threaded rod 4 drives the pressing plate 5 to move vertically downward until the pressing plate 5 moves down to contact the surface of the curtain cloth, so that the head and tail ends of the curtain cloth can be pressed and fixed. Then, the air pump 17 is started, and the air suction pipe 18 sucks air from the cloth suction cover 15, generating a strong adsorption force at the air permeable holes 14, and then the cloth adheres tightly to the surface of the cutting table 1. Through the dual fixation operations of the pressing mechanism and the adsorption mechanism, the cutting area of the curtain cloth can be fully covered, effectively pressing and fixing the curtain cloth, ensuring that the curtain cloth will not shift or slide during the cutting process, guaranteeing the neatness of the cutting edge, and greatly improving the quality and aesthetics of the curtain.

[0025] After the curtain cloth is fixed, when cutting, the second pneumatic cylinder 29 is started, and the second pneumatic rod drives the cutting knife 31 to move vertically downward to contact the surface of the cloth. At the same time, the second motor 25 is started, and the second lead screw 26 rotates. With the cooperation of the guide rod 28, the movable block 27 drives the cutting knife 31 to move, so that a moving cutting operation can be performed to meet the cutting requirements of curtain cloths of different widths. During the cutting process, the first motor 22 is started, and the first lead screw 23 rotates, and then the moving plate 24 drives the cutting mechanism to move, so that the cutting operation can be performed on different positions of the curtain cloth. During the cutting process, through the cooperation of the movable rod 32 and the spring 35, the pressing roller 34 always contacts the cloth, so that the cloth on both sides of the cutting knife 31 can be moved and pressed and fixed. The pressing roller 34 can move and press and fix in real time following the cutting knife 31, ensuring that the cutting area is always under a stable pressure, further preventing the curtain cloth from shifting or sliding during the cutting process. This real-time fixation method helps to maintain the accuracy of the cutting trajectory and improve the cutting accuracy.
