Description
Technical Field
[0001] The invention relates to the technical field of fabric cutting, in particular to a cutting device for clothing fabric and a cutting method thereof. Background Art
[0002] Fabric cutting equipment is suitable for the segmentation and cutting of various fabric materials. It is controlled by system software. The corresponding parameters are set on the operating platform. The computer transmits the corresponding instructions to the cutting machine, and then directly cuts the product. The cutting machine quickly cuts according to the accepted design drawings. It has high automation and simple operation. It is a cutting equipment used in many industries.
[0003] When cutting some lighter and thinner fabrics, in order to make the fabrics lay flat on the workbench, a vacuum adsorption device is usually set under the workbench to adsorb the fabrics flatly on the workbench surface through vacuum adsorption. At the same time, since the fabrics have good air permeability, in order to achieve better adsorption effect, a layer of plastic film is usually covered on the top of the fabric before each cutting. Due to the poor air permeability of this plastic film, the fabrics can be better pressed on the workbench surface. However, this method greatly increases the consumption of plastic film, increases the cost, and requires manual laying each time, resulting in low efficiency. In addition, after the cutting equipment has been used for too long, its internal moving structure is prone to wear, which leads to deviations in the cutting position. If it is not discovered in time, a large number of defective products will be produced, which increases costs and reduces production efficiency.
[0004] Therefore, a cutting device and a cutting method for clothing fabrics are proposed. Summary of the invention
[0005] The purpose of the present invention is to provide a cutting device for clothing fabrics and a cutting method thereof, which solves the problem of increased cost and low work efficiency caused by the need to cover the upper layer with a plastic film when dealing with thin fabrics. Cutting grooves are pre-arranged on fixed partitions and movable partitions according to cutting tracks, so that the plastic film can be replaced and reused. The thinness of the movable partition enables it to be covered on the surface of the fabric under the action of a vacuum adsorption mechanism, without the need for manual film coating of the fabric, thereby improving work efficiency and reducing costs.
[0006] To achieve the above object, the present invention provides the following technical solutions:
[0007] A cutting device for clothing fabrics comprises a workbench, a vacuum adsorption mechanism and a moving mechanism, wherein the vacuum adsorption mechanism is arranged inside the workbench, and the moving mechanism is connected to the workbench, and further comprises a cutter assembly, a mounting block, a fixed partition, a movable partition and a positioning groove, wherein the cutter assembly is connected to the moving mechanism, the mounting block is connected to the workbench, the four corners of the fixed partition are connected to the mounting block, the positioning groove is arranged on the fixed partition, the upper surface height of the positioning groove is lower than the upper surface height of the fixed partition, the movable partition is movably connected to the lower side of the fixed partition, and cutting grooves are provided at the same position on the fixed partition and the movable partition, the vacuum adsorption mechanism moves the movable partition downward by suction, the moving mechanism drives the cutter assembly to move to a specified position, the cutter assembly moves downward to above the positioning groove for cutting operation, and the cutter assembly stops cutting operation when the moving position of the moving mechanism deviates.
[0008] After the equipment has been used for too long, its internal moving structure is prone to wear, resulting in a slight deviation between the moving position and the set position. This deviation can easily lead to inaccurate cutting dimensions of the fabric, resulting in poor product quality. Through the above scheme, the positioning groove on the fixed partition can play an auxiliary positioning role. When the moving position of the cutter assembly deviates, the cutter assembly will be disconnected from the power source of the equipment, and no cutting operation will be performed at this time. This can not only prevent the fabric from being wasted, but also promptly remind the staff to discover the error of the equipment, and then promptly understand that the movement of the cutter assembly has deviated and needs to be debugged, effectively reducing the defective rate of the product; at the same time, the movable partition can replace the role of the plastic film in the traditional method. When the vacuum adsorption mechanism is working, it will be adsorbed downward to the surface of the fabric, assisting in flattening and fixing the fabric, and can be reused in the same batch of cutting operations, reducing production costs and improving production efficiency.
[0009] Preferably, the cutter assembly comprises a knife housing, an active block, a blade, a connecting block, a push groove, a connecting seat, a spring 1, a spring 2, a positioning block, a push rod, a reset plate and a spring 3, the knife housing is connected to a moving mechanism, the knife housing is cylindrical as a whole, the active block is connected to the knife housing, the connecting seat is connected to the knife housing, the two ends of the spring 1 are respectively connected to the knife housing and the connecting seat, the connecting block is connected to the connecting seat and is located at the lower side of the active block, the push groove is provided at the bottom of the connecting block, the two ends of the spring 2 are respectively connected to the connecting block and the connecting seat, the blade is connected to the lower side of the connecting block, the positioning block is connected to the knife housing, the push rod is provided at the top of the positioning block, the reset plate is connected to the knife housing, and the two ends of the spring 3 are respectively connected to the reset plate and the knife housing.
[0010] Through the above scheme, the positioning block can cooperate with the positioning groove. When the cutter assembly moves to just above the positioning groove, the lower surface of the knife shell and the upper surface of the fixed partition are at the same height. At this time, the positioning block is suspended in the positioning groove. At this time, the blade is connected to the active block through the connecting block. When the motor is started, the blade is driven to cut the cloth through the active block and the connecting block; when the movement of the cutter assembly deviates, a certain position of the positioning block will be squeezed upward by the fixed partition, and then the connecting block will be moved to both sides through the push rod and the push groove, thereby releasing the connection between the active block and the blade. At this time, the up and down movement of the active block cannot drive the blade to move, thereby stopping the cutting operation. When the cutting position deviates, the cutting of the cloth can be stopped in time, thereby preventing the cloth from being wasted, achieving the purpose of saving costs and stopping losses in time. At the same time, the stopping of the cutter assembly can timely remind the staff to inspect the equipment, avoid wasting time and raw materials due to inaccurate cutting, and further ensure production efficiency.
[0011] Preferably, the bottom of the positioning block is annular, and the outer diameter of the bottom of the positioning block is the same as the outer diameter of the knife housing.
[0012] Through the above solution, the bottom of the positioning block is the same as the outer diameter of the blade housing, so that it can assist in more accurate positioning of the blade.
[0013] Preferably, both sides of the active block and the blade are provided with sockets, and the connection block is connected with an insert block near the active block and the blade, and both the insert block and the socket are conical.
[0014] Through the above scheme, the cooperation between the plug block and the socket can make the transmission of the active block and the blade more stable. The conical shape of the plug block and the socket makes it easier for the two to cooperate with each other during movement. At the same time, the conical structure increases the contact area between the two, makes the force more uniform, and improves the service life of the parts.
[0015] Preferably, the cutting groove track is the same as the cutting track, and the width of the cutting groove is the same as the thickness of the blade.
[0016] Through the above scheme, the cutter cuts the cloth through the fixed partition and the movable partition. During the cutting process, it is possible to visually see whether the cutting position of the cutter is accurate, and it is also possible to effectively prevent the surface of the cloth from being contaminated, thereby reducing the loss of the cloth and ensuring the production cost. In addition, reducing the occurrence of problems during the production process can further ensure production efficiency.
[0017] Preferably, the positioning groove is wrapped around the cutting groove, the middle of the positioning groove is rectangular, the two ends of the positioning groove are semicircular, and the diameter of the positioning groove is the same as the outer diameter of the knife housing.
[0018] Through the above scheme, the shape of the positioning groove can cooperate with the bottom shape of the positioning block, which can assist the movement and positioning of the blade, making the cutting position more accurate, and then cooperate with the original positioning function of the equipment to enhance the accuracy of cutting, reduce the waste of raw materials caused by inaccurate cutting, and improve production efficiency.
[0019] Preferably, a plurality of sliding blocks are fixedly connected to the upper side of the movable partition, and the sliding blocks are slidably connected to the fixed partition. A spring four is wound around the sliding block, and the two ends of the spring four are respectively connected to the fixed partition and the movable partition. The fixed partition and the movable partition are both made of transparent plastic material, and the thickness of the movable partition is less than the thickness of the fixed partition.
[0020] Through the above scheme, the sliding block is slidably connected with the fixed partition, which can limit the position of the movable partition so that it will not shift during the up and down movement. The elastic force of spring four interacts with the downward suction force of the vacuum adsorption mechanism, making the downward movement of the movable partition smoother. In addition to smoothing and fixing the movable partition, it will not exert excessive squeezing force on the fabric to cause deformation of the fabric. The lightness of the movable partition enables it to be adsorbed downward by the vacuum adsorption mechanism, thereby replacing the plastic film wrapped on the fabric in the traditional way. Since it is reusable, the production cost is greatly reduced, and there is no need for frequent manual lamination, thereby improving production efficiency.
[0021] Preferably, counterweights are fixed to the bottoms of the four corners of the movable partition, and the coverage area of the movable partition is larger than the area of the cloth to be cut.
[0022] Through the above scheme, the pressing effect on the cloth is increased. Because the movable partition is relatively thin, and after adding the counterweight block, the middle part is light and the four corners are heavy. Therefore, when pressing on the cloth, the four corners will droop downward relative to the middle, thereby enhancing the covering and pressing effect on the middle cloth.
[0023] Preferably, a plurality of fixing rods are connected between two adjacent counterweight blocks, and a gap is left between the upper surface of the fixing rod and the movable partition.
[0024] Through the above solution, the four sides of the movable partition can be pressed down synchronously, thereby preventing one side from tilting up and causing a poor pressing effect.
[0025] A method for cutting clothing fabrics comprises the following steps:
[0026] S1: Check the operation of the equipment before cutting the garment fabrics;
[0027] S2: Lay the fabric to be processed flat on the workbench surface;
[0028] S3: Connect the fixed partition and the movable partition above the workbench through the mounting block;
[0029] S4: Start the vacuum adsorption mechanism to adsorb the cloth on the surface of the workbench, and adsorb the movable partition to move downward and press on the surface of the cloth;
[0030] S5: Start the moving mechanism to drive the cutter assembly to move to the specified position for cutting. When the moving position deviates from the specified position, the positioning block moves up to the inside of the knife housing and disconnects the active block from the blade through the connecting block, thereby stopping the cutting operation.
[0031] S6: Check and repair the equipment with problems;
[0032] S7: After the equipment is repaired, the cutter assembly operates normally and cuts the fabric into the specified shape.
[0033] Compared with the prior art, the present invention has the following beneficial effects:
[0034] 1. The present invention solves the problems of increased cost and low work efficiency caused by covering the upper layer of the fabric with a plastic film. Cutting grooves are pre-arranged on the fixed partition and the movable partition according to the cutting trajectory, so that the plastic film can be replaced and reused. The lightness and thinness of the movable partition enable it to be covered on the surface of the fabric under the action of a vacuum adsorption mechanism, thereby assisting in flattening and fixing the fabric. There is no need to manually coat the fabric with a film, thereby improving work efficiency and reducing costs.
[0035] 2. By setting the positioning block and the positioning groove, the two can cooperate with each other. When the cutter assembly moves to the specified position, the equipment will perform the cutting operation normally. When the movement of the cutter assembly deviates, the positioning block will be squeezed upward by the fixed partition, and then the connecting block will move to both sides through the push rod and the push groove, thereby releasing the connection between the active block and the blade. At this time, the up and down movement of the active block cannot drive the blade to move, and then the cutting operation is stopped, thereby preventing the cloth from being wasted, achieving the purpose of saving costs and stopping losses in time. At the same time, the stopping of the cutter assembly can promptly remind the staff to inspect the equipment, avoiding the waste of time and raw materials due to inaccurate cutting, and further ensuring production efficiency.
[0036] 3. By setting up movable partitions and counterweights, it can not only replace the role of plastic film in the traditional method, assist in flattening and fixing the cloth, and be reused in the same batch of cutting operations, reducing production costs, but also increase the pressing effect on the cloth through the counterweight. When the movable partition is pressed on the cloth, its four corners will droop downward relative to the middle under the action of the counterweight, thereby enhancing the covering and pressing effect on the middle cloth.

The cutter assembly 4 moves down to the top of the positioning groove 8 for cutting. When the moving position of the moving mechanism 3 deviates, the cutter assembly 4 stops cutting.
[0049] As an embodiment of the present invention, refer to Figure 2 , Figure 3 and Figure 4The cutter assembly 4 includes a knife housing 401, an active block 402, a blade 403, a connecting block 404, a push groove 405, a connecting seat 406, a spring 1 407, a spring 2 408, a positioning block 409, a push rod 410, a reset plate 411 and a spring 3 412. The knife housing 401 is connected to the moving mechanism 3. The knife housing 401 is cylindrical as a whole. A driving motor for driving the blade 403 to move up and down is arranged inside the moving mechanism 3. The active block 402 is connected to the driving motor. The active block 402 is slidably connected to the knife housing 401. The connecting seat 406 is connected to the knife housing 401. The two ends of the spring 1 407 are respectively connected to the knife housing 401 and the connecting seat 406. The connecting block 404 is connected to the connecting seat 406 and is located at the active block 40 2, the push groove 405 is arranged at the bottom of the connecting block 404, the two ends of the spring 408 are connected to the connecting block 404 and the connecting seat 406 respectively, the blade 403 is connected to the lower side of the connecting block 404, the active block 402 and the blade 403 are provided with a socket 413 on both sides, the connecting block 404 is connected with a plug block 414 near the active block 402 and the blade 403, the cooperation of the plug block 414 and the socket 413 can make the transmission of the active block 402 and the blade 403 more stable, the plug block 414 and the socket 413 are both conical, and the conical shape of the plug block 414 and the socket 413 makes it easier for the two to cooperate with each other during the movement. At the same time, the conical structure increases the contact area between the two, makes the force more uniform, and improves the parts The service life of the blade 403 is improved. The positioning block 409 is connected to the blade housing 401. The bottom of the positioning block 409 is annular. The middle part of the positioning block 409 is located on both sides of the blade 403 as a semi-annular plate. The outer diameter of the bottom of the positioning block 409 is the same as the outer diameter of the blade housing 401.

The positioning block 409 can cooperate with the positioning groove 8. The push rod 410 is arranged on the top of the positioning block 409. When the push rod 410 moves upward, it will cooperate with the push groove 405, thereby pushing the connecting block 404 to move away from the active block 402. The reset plate 411 is connected to the blade housing 401, and the two ends of the spring three 412 are respectively connected to the reset plate 411 and the blade housing 4 01 is connected, when the cutter assembly 4 moves to just above the positioning slot 8, the lower surface of the knife housing 401 and the upper surface of the fixed partition 6 are at the same height, and the positioning block 409 is suspended in the positioning slot 8. At this time, the blade 403 is connected to the active block 402 through the connecting block 404. When the motor is started, the active block 402 and the connecting block 404 drive the blade 403 to cut the cloth; when the movement of the cutter assembly 4 deviates, a certain position of the positioning block 409 will be squeezed upward by the fixed partition 6, and then the connecting block 404 will be moved to both sides through the push rod 410 and the push slot 405, thereby releasing the connection between the active block 402 and the blade 403. At this time, the up and down movement of the active block 402 cannot drive the blade 403 to move, thereby stopping the cutting operation.
[0050] As an embodiment of the present invention, refer to Figure 5 , Figure 6 , Figure 7 and Figure 8 The fixed partition 6 and the movable partition 7 are both provided with cutting grooves 9 at the same position. The cutting groove 9 has the same trajectory as the cutting trajectory. The width of the cutting groove 9 is the same as the thickness of the blade 403. When cutting, the cutter cuts the cloth across the fixed partition 6 and the movable partition 7. It can not only visually see whether the cutting position of the cutter is accurate during the cutting process, but also effectively prevent the surface of the cloth from being contaminated. The positioning groove 8 is covered around the cutting groove 9. The middle part of the positioning groove 8 is rectangular, and the two ends of the positioning groove 8 are semicircular. The straightness of the positioning groove 8 is 90°. The diameter value is the same as the outer diameter value of the blade housing 401. The shape of the positioning groove 8 can cooperate with the bottom shape of the positioning block 409, which can assist the movement and positioning of the blade 403 to make the cutting position more accurate. A plurality of sliding blocks 10 are fixedly connected to the upper side of the movable partition 7. The sliding blocks 10 are slidably connected to the fixed partition 6. The sliding blocks 10 are slidably connected to the fixed partition 6, which can limit the position of the movable partition 7 so that it will not deviate during the up and down movement. A spring four 11 is wound around the sliding block 10, and the two ends of the spring four 11 are respectively connected to the The fixed partition 6 and the movable partition 7 are connected, and the elastic force of the spring four 11 interacts with the downward suction of the vacuum adsorption mechanism 2, so that the process of the movable partition 7 moving downward is softer, so that the movable partition 7 can not only achieve the effect of smoothing and fixing, but also will not exert excessive squeezing force on the cloth to cause deformation of the cloth. The fixed partition 6 and the movable partition 7 are both made of transparent plastic material, and the thickness of the movable partition 7 is less than that of the fixed partition 6, so that the movable partition 7 can better simulate the effect of the plastic film in the traditional way, and the four corners and bottoms of the movable partition 7 are fixed. There is a counterweight block 12, and the movable partition 7 is relatively light and thin. After the counterweight block 12 is added, the middle part is light and the four corners are heavy. Therefore, when pressed on the cloth, the four corners will droop downward relative to the middle, thereby enhancing the covering and pressing effect on the middle cloth. The covering area of the movable partition 7 is larger than the area of the cloth to be cut. A plurality of fixing rods 13 are connected between two adjacent counterweight blocks 12, so that the four sides of the movable partition 7 can be pressed down synchronously, thereby preventing one side from warping and causing a poor pressing effect. A gap is left between the upper surface of the fixing rod 13 and the movable partition 7.
[0051] The specific working principle is as follows: first, the cloth to be cut is laid flat on the surface of the workbench 1, and then the fixed partition 6 and the movable partition 7 are installed above the workbench 1 through the mounting block 5, and the fixed partition 6 and the movable partition 7 are adjusted to a suitable position by adjusting the height of the mounting block 5, and then the vacuum adsorption mechanism 2 is started to adsorb the cloth on the surface of the workbench 1, and at the same time, the vacuum adsorption mechanism 2 adsorbs the movable partition 7, so that it moves downward and presses on the surface of the cloth, and then the moving mechanism 3 is started to drive the cutter assembly 4 to move to the designated position for cutting operation;
[0052] When the moving position is consistent with the set position, the positioning block 409 will be located directly above the positioning slot 8, and the height of the lower surface of the positioning block 409 will be level with the height of the upper surface of the fixed partition 6. At this time, the lower end of the positioning block 409 will be suspended in the positioning slot 8 and will not contact the upper surface of the positioning slot 8. At this time, the blade 403 will be connected to the active block 402 through the connecting block 404. When the driving motor is started, the blade 403 will be driven to move up and down through the active block 402, thereby cutting the cloth.
[0053] When the moving position deviates from the set position, the positioning block 409 will not be directly above the positioning groove 8, and the lower end of the positioning block 409 will be squeezed upward by the fixed partition 6. When the positioning block 409 moves upward, the push rod 410 and the push groove 405 cooperate to make the connecting block 404 move to both sides, thereby releasing the transmission connection between the active block 402 and the blade 403. At this time, the active block 402 cannot drive the blade 403 to move when moving up and down, and the blade 403 will also be retracted into the knife housing 401 under the action of the reset plate 411 and the spring three 412, thereby stopping the cutting operation.
[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
