Description

Technical Field

[0001] The invention relates to the technical field of clothing production, in particular to an automatic cloth edge trimming device for clothing production. Background Art

[0002] During the garment production process, it is necessary to cut off the excess fabric used for garment production to meet the needs of subsequent garment processing.

[0003] At present, in order to ensure the efficiency of edge trimming, the fabric is usually rolled up and pulled by a winding mechanism, and the edge materials on both sides of the fabric are cut by a cutting knife. During the process of being pulled up and rolled up, the fabric is prone to deviation or wrinkles due to the contact of the cutting knife, resulting in uneven edge trimming, which directly affects the subsequent garment processing and even causes the fabric to be scrapped.

[0004] In the prior art, in order to ensure the smoothness of the edge of the cloth, during the edge trimming process, the cloth is stretched and straightened using structures such as splints or support plates, and then the cloth is trimmed. This method can effectively avoid wrinkles on the cloth, thereby ensuring the smoothness of the edge. However, the cloth cannot be rolled up at the same time during the edge trimming process, which affects the continuity of the cloth trimming process. Therefore, it is urgent to design a trimming device that can continuously transport the cloth without stopping the machine, realize edge trimming and ensure the smoothness of the edge.

[0045] Beneficial effects of the present invention:

[0046] 1. An inclined roller is arranged on the movable plate. In the vertical direction, there is an angle a between the axis of the roller and the central axis of the workbench. During the rotation of the roller, an inclined outward force F is applied to the cloth. The force F can be decomposed into a force F parallel to the central axis of the workbench and a force F perpendicular to the central axis of the workbench. The force F can be superimposed on the traction force applied by the winding assembly, thereby helping the winding assembly to feed and wind the cloth. The force F is perpendicular to the traction force of the winding assembly, thereby pulling the cloth outward to keep the cloth straight. Under the dual action of the force F and the force F, the cloth is subjected to tension in the horizontal and vertical directions, so that the cloth can be fully tensioned during the trimming process to avoid wrinkles in the cloth and affect the trimming quality.

[0047] 2. An inclined roller is set to tighten and straighten the fabric. The roller can provide lateral tension to the fabric and generate relative movement with the fabric. Compared with the traditional method of using fixed splints or support plates to stretch the fabric to both sides, it does not affect the continuous conveying and trimming of the fabric, which greatly improves the trimming efficiency and operation continuity.

[0048] 3. A cutting knife with an oscillating effect is provided. Compared with the traditional structure in which the cutting knife is fixedly installed on the workbench, the present invention drives the cutting knife to oscillate at a high frequency through an oscillating component, thereby cutting the cloth back and forth, which can effectively avoid the occurrence of cutting failure, thereby ensuring the continuity of cloth conveying, and will not cause the cloth to get stuck or torn, and the trimming process is more stable and reliable;

[0049] 4. The first guide roller and the second guide roller are rotatably installed at both ends of the workbench, and the first guide roller and the second guide roller at both ends are used to guide the cloth. No matter how the cloth thickness on the unwinding assembly and the winding assembly changes, it can be ensured that the cloth between the first guide roller and the second guide roller is always kept in a horizontal state and flatly laid on the fixed plate, thereby ensuring the stability and accuracy of the trimming process;

[0050] 5. A collection box is installed on the fixed plate, and an exhaust fan is arranged on the inner wall of the collection box; during the trimming process, the negative pressure generated by the exhaust fan can suck the edge materials cut by the cutting knife into the collection box, thereby realizing automatic collection of the edge materials, preventing the edge materials from being scattered everywhere, and improving the cleanliness of the equipment;

[0051] 6. The roller close to the winding assembly also has the function of assisting material collection. The roller close to the winding assembly is used to roll the complete fabric and the edge material laterally. The complete fabric in the middle is tensioned, and the edge material is separated from the complete fabric under the rolling of the roller, and then peeled outward by the roller, making it easier for the edge material to be sucked into the collection box by the exhaust fan, thereby improving the collection effect of the edge material.

DETAILED DESCRIPTION

[0061] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0062] See also Figure 1 and Figure 2As shown, the present invention discloses an automatic fabric trimming device for clothing production, which can be used to improve the problem that the existing equipment cannot take into account the non-stop continuous conveying and smooth trimming of fabrics. Specifically, the automatic fabric trimming device for clothing production may include a workbench 1, a slide rail 2, a slider 3, a fixed frame 4, a fixed plate 7, a movable plate 8, a roller 13, a roller motor 14, a cutting mechanism, an adjustment mechanism, a winding component and an unwinding component, etc.; wherein the slide rail 2 is provided with two groups and symmetrically distributed on both sides of the workbench 1; the slider 3 is slidably embedded in the corresponding slide rail 2; the fixed frame 4 is fixedly connected to the corresponding slider 3, and the fixed frame 4 is provided with a first cross bar 5 and a second cross bar 6 from bottom to top; the fixed plate 7 is fixedly arranged on the first cross bar 5 for supporting and laying the cloth, and a through slot 15 is vertically opened in the middle of the fixed plate 7; the movable plate 8 is arranged on the second cross bar 6 in a liftable manner; the roller 13 is rotatably mounted on the bottom surface of the movable plate 8 through the first mounting seat 12; in the vertical direction, there is an angle a between the axis of the roller 13 and the central axis of the workbench 1, wherein 0°<a<90°; the roller motor 14 is mounted on the first mounting seat 12 for driving the roller 13 to rotate; the cutting mechanism is arranged on the fixed plate 7 for cutting the cloth; the adjusting mechanism is arranged on the workbench 1 for driving the slide rails 2 on both sides to move; the winding assembly is arranged at one end of the workbench 1, and the unwinding assembly is arranged at the other end of the workbench 1;

[0063] Specifically, one end of the cloth on the unwinding assembly is pulled through between the movable plate 8 and the fixed plate 7 and then wound on the winding assembly. The cloth between the winding assembly and the unwinding assembly can just be laid flat on the fixed plate 7. The movable plate 8 moves downward relative to the second cross bar 6 until the roller 13 contacts the cloth on the fixed plate 7, thereby pressing the cloth on the fixed plate 7; during the edge trimming process, the winding assembly gradually rolls up the cloth, so that the cloth is horizontally fed along the fixed plate 7 toward one side of the winding assembly. During the movement of the cloth, the cutting mechanism cuts the cloth and cuts off the excess edge material on the side of the cloth. At the same time, the drum motor 14 drives the drum 13 to rotate. Since the drum 13 is inclined relative to the workbench 1, the drum 13 can provide the cloth with a lateral driving force parallel to the feeding direction and a longitudinal tensioning force perpendicular to the feeding direction, ensuring that the cloth can always be longitudinally stretched outward and straightened during the edge trimming process, thereby avoiding wrinkles in the cloth and affecting the flatness of the edge trimming incision.

[0064] Please note that Figure 3 and Figure 4As shown, the main core improvement of the present invention is that an inclined roller 13 is arranged on the movable plate 8, and in the vertical direction, there is an angle a between the axis of the roller 13 and the central axis of the workbench 1. In this way, the roller 13 will apply an inclined outward force F to the cloth during the rotation process, and the force F can be decomposed into a force F1 parallel to the central axis of the workbench 1 and a force F2 perpendicular to the central axis of the workbench 1, wherein the force F1 can be superimposed with the traction force applied by the winding assembly, thereby helping the winding assembly to feed and wind the cloth, and the force F2 is perpendicular to the traction force of the winding assembly, thereby pulling the cloth outward to keep the cloth straight all the time, and under the dual action of the force F1 and the force F2, the cloth is subjected to tension in the horizontal and vertical directions, so that the cloth can be fully tensioned during the trimming process to avoid wrinkles in the cloth and affect the trimming quality.

[0065] It should be further explained that, in the prior art, in order to prevent the cloth from wrinkling during the trimming process, fixed splints or support plates are usually used to stretch the cloth to both sides and tighten it. Although this tensioning method can also ensure that the cloth does not wrinkle, this fixed structure requires the cloth to be tightened and fixed before trimming can be performed. In other words, this fixing method will affect the normal transportation of the cloth, thereby making it impossible to achieve uninterrupted trimming operations, affecting processing efficiency and operation continuity; while in the present invention, an inclined roller 13 is provided to tighten and straighten the cloth. The roller 13 can provide lateral tension to the cloth while generating relative movement with the cloth, thereby not affecting the continuous transportation of the cloth and the trimming process, which greatly improves the trimming efficiency and operation continuity.

[0066] Furthermore, in the vertical direction, the angle a between the axis of the roller 13 and the central axis of the workbench 1 is in the range of 0°<a<90°, wherein the larger the angle a is, the larger the force F1 is and the smaller the force F2 is; the smaller the angle a is, the smaller the force F1 is and the larger the force F2 is; when the angle a is too large, the vertical component of force applied by the roller 13 to the cloth is too small, thereby failing to provide a good longitudinal tensioning force, and easily causing the cloth to wrinkle; when the angle a is too small, the vertical component of force applied by the roller 13 to the cloth is too large, and easily causing the cloth to be too tight, while increasing the resistance to the horizontal feeding of the cloth; therefore, the range of the angle a is preferably 30°<a<60°, and when a is 45°, the force F1 is equal to the force F2, which can ensure that the vertical component of force applied by the roller 13 to the cloth is moderate, ensure the cloth is tensioned, and avoid wrinkles, and at the same time effectively reduce the resistance during the cloth feeding process.

[0067] In addition, in order to make the roller 13 press against the fabric to provide the fabric with sufficient and stable tension, please refer to Figure 5As shown, a lifting rod 9 is vertically fixed on the movable plate 8, and the lifting rod 9 slides through the second cross bar 6. A handle 11 is fixed on the end of the lifting rod 9, and a first spring 10 is arranged between the second cross bar 6 and the movable plate 8, and the first spring 10 is movably sleeved on the lifting rod 9; the elastic force of the first spring 10 is used to push the movable plate 8 downward, so that the roller 13 can always be pressed against the upper surface of the cloth on the fixed plate 7, avoiding slippage between the roller 13 and the cloth and affecting the tensioning effect; and when the cloth needs to be taken out or cleaned and maintained, the handle 11 can be held to lift the entire movable plate 8 upward, so that the roller 13 is separated from the fixed plate 7, and the operation is convenient and quick.

[0068] In one embodiment, see Figure 5 As shown, the cutting mechanism includes a guide rod 16, a lifting plate 17, a cutting knife 18 and an oscillating assembly, wherein the guide rod 16 is provided with two groups and is symmetrically and vertically fixed on both sides of the bottom surface of the fixed plate 7, and the lifting plate 17 is slidably sleeved on the guide rod 16; the cutting knife 18 is installed on the lifting plate 17 and movably penetrates the through slot 15, and the blade of the cutting knife 18 faces the side of the unwinding assembly; the oscillating assembly is provided on the fixed plate 7, and is used to drive the cutting knife 18 to move up and down; during the conveying and feeding process of the cloth, the lifting plate 17 is driven by the oscillating assembly to reciprocate up and down along the guide rod 16, thereby driving the cutting knife 18 to vibrate frequently up and down, and the cutting knife 18 that moves back and forth is used to cut the cloth, thereby improving the reliability of edge cutting;

[0069] The specific structure of the oscillating component is not limited. In this embodiment, please refer to Figure 6 As shown, the oscillation assembly includes a second spring 19, a second mounting seat 20, an oscillation motor 21 and a cam 22; wherein the second spring 19 is movably sleeved on the corresponding guide rod 16 and is located between the fixed plate 7 and the lifting plate 17; the second mounting seat 20 is fixed to the bottom surface of the fixed plate 7, the oscillation motor 21 is mounted on the second mounting seat 20, and the cam 22 is mounted on the output shaft of the oscillation motor 21 and abuts against the lifting plate 17; the oscillation motor 21 drives the cam 22 to rotate, and when the protruding part of the cam 22 contacts the lifting plate 17, the lifting plate 17 is pushed to rise along the guide rod 16, and when the non-protruding part of the cam 22 contacts the lifting plate 17, under the thrust of the second spring 19, the lifting plate 17 descends along the guide rod 16, and so on, thereby realizing high-speed oscillation of the lifting plate 17, and then driving the cutting knife 18 to oscillate and cut the cloth back and forth;

[0070] It should be noted that the purpose of providing the cutting knife 18 with an oscillating effect is that, taking into account that in the prior art, the cutting knife 18 is usually fixedly mounted on the workbench 1, and the cloth is trimmed only by the relative movement between the cloth and the cutting knife 18 when the cloth is fed forward. However, since the cutting knife 18 is fixed, cutting failure may occasionally occur, resulting in the cutting knife 18 blocking the cloth, affecting the continuous conveying of the cloth, and even causing the cloth to tear and the entire equipment to stop suddenly in severe cases. In the present invention, the cutting knife 18 is driven to oscillate at a high frequency by an oscillating component, thereby cutting the cloth back and forth, which can effectively avoid the occurrence of cutting failure, thereby ensuring the continuity of cloth conveying, and will not cause the cloth to get stuck or torn, and the trimming process is more stable and reliable.

[0071] In another embodiment, in order to adapt to the cutting operation of fabrics of different widths, the spacing between the fixing plates 7 on both sides can be adjusted by an adjustment mechanism, see Figure 7 As shown, the adjusting mechanism includes an adjusting motor 23, a gear 24 and a rack 25; wherein the adjusting motor 23 is fixedly mounted on the workbench 1, the gear 24 is mounted on the output shaft of the adjusting motor 23, the rack 25 is fixedly connected to the corresponding slider 3, and the rack 25 and the gear 24 are meshed for transmission; the adjusting motor 23 drives the gear 24 to rotate, and the meshing transmission of the gear 24 and the rack 25 is utilized to drive the sliders 3 on both sides to approach or move away synchronously, thereby realizing the adjustment of the spacing between the fixing plates 7 on both sides, so as to adapt to the edge trimming operation of fabrics of different widths;

[0072] For further information, see Figure 1 and Figure 2 As shown, the winding assembly includes a third mounting seat 26, a winding roller 27 and a winding motor 28, wherein the third mounting seat 26 is fixed to one end of the workbench 1, the winding roller 27 is rotatably mounted on the third mounting seat 26, and the winding motor 28 is fixedly mounted on the third mounting seat 26, and is used to drive the winding roller 27 to rotate; the winding motor 28 drives the winding roller 27 to rotate, so that the trimmed cloth can be wound;

[0073] Similarly, the unwinding assembly includes a fourth mounting seat 29 and an unwinding roller 30, wherein the fourth mounting seat 29 is fixed to one end of the workbench 1 away from the third mounting seat 26, and the unwinding roller 30 is rotatably mounted on the fourth mounting seat 29; the cloth to be trimmed is wound on the unwinding roller 30, and when the winding roller 27 rotates, the unwinding roller 30 will also rotate adaptively under the traction of the cloth, thereby completing the transfer of the cloth;

[0074] Furthermore, in order to ensure that the cloth is always flatly attached to the fixed plate 7 during the trimming process, the first guide roller 31 and the second guide roller 32 are rotatably installed at both ends of the workbench 1, wherein the first guide roller 31 is located between the winding assembly and the fixed plate 7, and the second guide roller 32 is located between the unwinding assembly and the fixed plate 7; the lowest points of the first guide roller 31 and the second guide roller 32 are flush with the upper end surface of the fixed plate 7; a section of cloth on the unwinding assembly first passes through the bottom of the second guide roller 32, then passes through the upper end surface of the fixed plate 7 and passes through the bottom of the first guide roller 31, and finally is wound on the unwinding assembly, and the first guide roller 31 and the second guide roller 32 at both ends are used to guide the cloth. In this way, no matter how the thickness of the cloth on the unwinding assembly and the winding assembly changes, it can be ensured that the cloth between the first guide roller 31 and the second guide roller 32 is always kept in a horizontal state and flatly attached to the fixed plate 7, thereby ensuring the stability and accuracy of the trimming process.

[0075] In yet another embodiment, see Figure 5 As shown, a collecting box 33 is installed on the fixed plate 7, the opening of the collecting box 33 is aligned with the roller 13 close to the winding assembly, and an exhaust fan 34 is arranged on the inner wall of the collecting box 33 away from the fixed plate 7; during the trimming process, the negative pressure generated by the exhaust fan 34 can suck the edge material cut by the cutting knife 18 into the collecting box 33, thereby realizing automatic collection of the edge material, avoiding the edge material from being scattered everywhere, and improving the cleanliness of the equipment;

[0076] It should be noted that, in this embodiment, the roller 13 close to the winding assembly has the function of not only laterally tensioning the cloth, but also assisting in collecting the cloth. The complete cloth and the edge material after trimming by the cutting knife 18 arrive at the opening of the collecting box 33 together under the traction of the winding assembly. At this time, the roller 13 close to the winding assembly rolls the complete cloth and the edge material laterally, and the complete cloth in the middle is tensioned, while the edge material is separated from the complete cloth under the rolling of the roller 13, and is thus peeled off to the outside by the roller 13, so that the edge material can be more easily sucked into the collecting box 33 by the exhaust fan 34, thereby improving the collection effect of the edge material.

[0077] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
