DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] In order to make the technical means, creative features, achieved purposes and functions realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0032] As Figures 1 to 6 shown, a woolen overcoat processing device of the present invention includes a placement plate 1. A sliding groove 11 is formed on the side of the placement plate 1. An installation frame 2 is installed in the sliding groove 11. The installation frame 2 is driven by a lead screw 12 driven by a motor installed in the sliding groove 11. An installation block 22 is installed on the installation frame 2. The installation block 22 is driven by a lead screw 21 driven by a motor installed on the installation frame 2. An electric push rod 3 is installed on the installation block 22. A cutting head 31 is installed at the lower end of the electric push rod 3. A cutting knife 311 and a sewing needle 312 are installed on the cutting head 31;

[0033] A snap fastener 4 is installed on the placement plate 1. The snap fastener 4 fixes the woolen overcoat by its own elasticity. A support 32 is installed on the cutting head 31. A pressing plate 321 is installed on the support 32. When the cutting head 31 cuts, the pressing plate 321 contacts the surface of the woolen overcoat;

[0034] Through holes 13 are evenly formed on the placement plate 1. A fixing column 41 is installed on the snap fastener 4. The lower end of the fixing column 41 is inserted into the through hole 13;

[0035] When trimming the corners of the woolen overcoat to prepare for subsequent clothing processing work, the staff lays the woolen overcoat to be cut flat on the placement plate 1. Then, the staff inserts the fixing column 41 into the through hole 13 near the edge of the woolen overcoat to be cut, so that the distance between the snap fastener 4 and the woolen overcoat on the placement plate 1 is appropriate. Then, the staff lifts the snap fastener 4 upward so that the edge of the woolen overcoat is placed under the snap fastener 4. The snap fastener 4 fixes the woolen overcoat by its own elasticity, ensuring that the woolen overcoat can be kept fixed when cutting the corners of the woolen overcoat, thus avoiding cutting mistakes and affecting subsequent continuous processing and the quality of the obtained woolen overcoat. At the same time, when cutting, the controller controls the motors corresponding to the lead screw 12 and the lead screw 21 to run, so that the cutting head 31 moves to the part of the woolen overcoat to be cut. Then, under the control of the controller, the cutting head 31 moves on the surface of the woolen overcoat to complete the cutting of the corners of the woolen overcoat, without too much manual processing, improving work efficiency. After cutting, the controller controls the cutting head 31 to return to the initial position. Then, the staff removes the snap fastener 4 to release the fixing effect on the woolen overcoat and removes the woolen overcoat from the placement plate 1 for storage for subsequent processing use;

[0036] Meanwhile, by providing a plurality of through holes 13 on the placement plate 1, the fixing posts 41 and the snap fasteners 4 can easily change their positions on the placement plate 1, thereby adapting to the cutting of the corners of woolen overcoats of different sizes and specifications, improving the applicable range of the processing equipment. Additionally, after the snap fastener 4 fixes the woolen overcoat by its own elasticity, the snap fastener 4 will generate a lateral force on the fixing post 41, causing the fixing post 41 to get stuck and fixed in the through hole 13, thus preventing the fixing post 41 from detaching from the through hole 13 during the cutting of the woolen overcoat, resulting in the failure of the snap fastener 4 to fix the woolen overcoat and affecting the normal operation of the processing equipment;

[0037] Meanwhile, through the pressing plate 321 installed on the cutting head 31, when the electric push rod 3 moves downward and the cutting head 31 contacts the surface of the woolen overcoat for cutting, the pressing plate 321 also contacts the surface of the woolen overcoat and generates a certain squeezing effect, thereby flattening and pressing the vicinity of the part being cut by the cutting head 31 to ensure that the woolen overcoat near the cutting head 31 does not wrinkle or deform during cutting, ensuring good cutting effect.

[0038] As an embodiment of the present invention, the fixing post 41 has magnetism, and friction points 42 are uniformly arranged on the surface of the snap fastener 4 that contacts the woolen overcoat;

[0039] Since the surface of the woolen overcoat is relatively smooth, by providing friction points 42 on the snap fastener 4, when the snap fastener 4 fixes the woolen overcoat by its own elasticity, the friction points 42 provided on the surface of the snap fastener 4 can increase the friction force between the snap fastener 4 and the woolen overcoat as much as possible without damaging the surface of the woolen overcoat, improving the fixing effect of the snap fastener 4 on the woolen overcoat, and avoiding the woolen overcoat from being affected by excessive external forces, such as the acting force of the cutting knife 311 or the sewing needle 312 on the woolen overcoat during cutting, resulting in relative sliding between the woolen overcoat and the snap fastener 4, causing the fixing of the woolen overcoat to fail and affecting the normal operation of the processing equipment. At the same time, since the fixing post 41 itself has magnetism, after the staff inserts the fixing post 41 into the through hole 13 on the placement plate 1, the fixing post 41 can stably stay in the through hole 13 under the action of its own magnetic force, avoiding the fixing post 41 and the snap fastener 4 from slipping out of the through hole 13 when fixing the woolen overcoat, or after the processing equipment is used for a long time, the edge of the through hole 13 and the surface of the fixing post 41 are worn, and the fixing post 41 cannot be stably fixed in the through hole 13, thus affecting the normal operation of the processing equipment or the quality of the cut corners of the woolen overcoat.

[0040] As an embodiment of the present invention, a fixing block 5 is placed on the placement plate 1, the fixing block 5 has magnetism, and the fixing block 5 is located on the surface of the woolen overcoat;

[0041] After the woolen overcoat is placed on the placement plate 1, the through hole 13 located below the woolen overcoat is blocked, and the fixing post 41 cannot be fixed through the through hole 13 in this part. Therefore, the position where the fixing post 41 is located is at the edge of the woolen overcoat. At the same time, since the area of the woolen overcoat is relatively large, the position where the cutting head 31 cuts on the woolen overcoat is relatively far from the position where the fixing post 41 is located. Therefore, when the cutting head 31 cuts, there may be certain wrinkles, slackness, and curling at the cut position on the woolen overcoat, affecting the cutting effect of the cutting head 31 on the woolen overcoat and the subsequent processing of the woolen overcoat after cutting;

[0042] At the same time, by placing the fixing block 5 on the woolen overcoat and utilizing the mutual attraction between the fixing block 5 itself and the placement plate 1, the fixing block 5 presses and fixes the position where it is located on the woolen overcoat, avoiding situations such as wrinkles at the cutting part of the woolen overcoat, which affect the cutting effect of the woolen overcoat and the normal operation of the processing equipment. At the same time, by placing the fixing block 5 near the cutting area on the woolen overcoat and pressing and fixing the woolen overcoat through the fixing block 5, the cutting area on the woolen overcoat can be in a relatively taut state, facilitating the cutting of the corners of the woolen overcoat by the cutting head 31 and improving the cutting effect and cutting efficiency after cutting.

[0043] As an implementation manner of the present invention, a protrusion 51 is provided on the lower surface of the fixing block 5, and the size of the protrusion 51 matches the diameter of the through hole 13;

[0044] Since the fixing block 5 presses and fixes the woolen overcoat through the mutual attraction between itself and the placement plate 1, when the thickness of the woolen overcoat is relatively large or the woolen overcoat is subjected to a large external force, there is a possibility that the fixing block 5 is affected and thus affects the fixation of the woolen overcoat. At the same time, since the through holes 13 on the placement plate 1 are uniformly arranged and there are multiple, by providing a protrusion 51 on the fixing block 5 that matches the size of the through hole 13, after the staff places the fixing block 5 on the woolen overcoat, under the action of the magnetic attraction between the fixing block 5 and the placement plate 1, the protrusion 51 on the fixing block 5 will press down the area on the woolen overcoat corresponding to the through hole 13, so that part of the area where the woolen overcoat is close to the placement plate 1 sinks into the through hole 13, thereby improving the fixing effect of the fixing block 5 on the woolen overcoat, avoiding the sliding of the woolen overcoat and the fixing block 5 on the woolen overcoat relative to the placement plate 1, thus ensuring the fixing effect on the woolen overcoat and improving the effect after cutting the woolen overcoat.

[0045] As an implementation manner of the present invention, a guide roller 322 is installed on the lower surface of the pressing plate 321, and there is relative rotation between the guide roller 322 and the pressing plate 321;

[0046] When the cutting head 31 cuts the corners of the woolen overcoat, the cutting head 31 moves relative to the woolen overcoat, so that the pressing plate 321 installed on the cutting head 31 through the bracket 321 will also move on the surface of the woolen overcoat. At the same time, by installing a guide roller 322 on the pressing plate 321 and making the guide roller 322 rotate relative to the pressing plate 321, it is convenient for the pressing plate 321 to move on the surface of the woolen overcoat, reduce the friction between the pressing plate 321 and the woolen overcoat, and prevent the pressing plate 321 from driving the woolen overcoat when it moves, affecting the fixing effect of the woolen overcoat and the effect after the woolen overcoat is cut.

[0047] As an embodiment of the present invention, a connecting frame 61 is installed on the cutting head 31, a suction pipe 6 is installed on the connecting frame 61, the suction pipe 6 is connected to an external negative pressure fan, and the suction pipe 6 is located behind the cutting head 31 in the advancing direction;

[0048] When cutting the corners of the woolen overcoat, the structure at the cutting part of the woolen overcoat is damaged, so waste materials, fluff or dust will be generated. By installing a suction pipe 6 on the cutting head 31 and using an external negative pressure fan to collect the fluff and dust generated during the cutting process, it is possible to avoid the diffusion and distribution of fluff and dust in the workshop, which may affect the health of the staff and pose potential safety hazards.

[0049] As an embodiment of the present invention, a brush 62 is installed on the lower end surface of the suction pipe 6, a notch is provided on the side of the brush 62 close to the cutting head 31, and the brush 62 contacts the surface of the woolen overcoat when the cutting head 31 cuts;

[0050] By providing a brush 62 on the lower end surface of the suction pipe 6, the brush 62 is used to seal the gap between the suction pipe 6 and the woolen overcoat to a certain extent, improve the negative pressure suction force of the notch of the brush 62 facing the cutting head 31, so as to collect the fluff, waste materials and dust generated during the cutting process as much as possible, avoid potential safety hazards and ensure the health of the staff. At the same time, by sweeping and brushing the surface of the woolen overcoat with the brush 62, the number of fluff, waste materials and dust attached to the surface of the woolen overcoat can be reduced, the cleanliness of the surface of the woolen overcoat can be ensured, and the subsequent processing steps of the woolen overcoat can be reduced.

[0051] A processing technology for woolen overcoats, the processing technology is applicable to the woolen overcoat processing equipment described in any one of the above, and the processing technology includes the following steps:

[0052] S1: The staff places the woolen overcoat to be processed flat on the placement plate 1, and then the staff inserts the buckle 4 into the edge position of the woolen overcoat through the fixing column 41 to fix the woolen overcoat as a whole;

[0053] S2: The staff places the fixing block 5 along the area to be cut on the woolen overcoat, and uses the fixing block 5 to fix the area to be cut on the woolen overcoat.

[0054] S3: The staff starts the processing equipment through the controller, so that the electric push rod 3 extends to make the cutting head 31 contact the woolen overcoat to start cutting. At the same time, the controller starts the external negative pressure fan to collect the waste generated by cutting; during the cutting process, the controller controls the motors corresponding to the first lead screw 12 and the second lead screw 21 to run, driving the cutting knife to move along the area to be cut on the woolen overcoat to complete the cutting of the woolen overcoat.

[0055] S4: The staff turns off the processing equipment through the controller to make the cutting head 31 return to the initial position. Then, the fixing block 5 and the snap fastener 4 are removed to release the fixation of the woolen overcoat, and the woolen overcoat is removed and stored.

[0056] The specific working process is as follows:

[0057] The staff places the woolen overcoat to be cut flat on the placement plate 1. After that, the staff inserts the fixing column 41 into the through hole 13 near the edge of the woolen overcoat to be cut. Then, the staff lifts the snap fastener 4 upward so that the edge of the woolen overcoat is placed under the snap fastener 4, and uses the elasticity of the snap fastener 4 itself to fix the woolen overcoat. At the same time, during cutting, the controller controls the motors corresponding to the first lead screw 12 and the second lead screw 21 to run, so that the cutting head 31 moves to the part of the woolen overcoat to be cut. Then, under the control of the controller, the cutting head 31 moves on the surface of the woolen overcoat to complete the cutting of the corners of the woolen overcoat. After cutting, the controller controls the cutting head 31 to return to the initial position. Then, the staff removes the snap fastener 4 to release the fixing effect on the woolen overcoat, and removes the woolen overcoat from the placement plate 1 and stores it.

[0058] At the same time, by arranging a plurality of through holes 13 on the placement plate 1, the fixing column 41 and the snap fastener 4 can easily change their positions on the placement plate 1. In addition, after the snap fastener 4 fixes the woolen overcoat by its own elasticity, the snap fastener 4 will generate a lateral force on the fixing column 41, causing the fixing column 41 to get stuck and fixed in the through hole 13.

[0059] At the same time, through the pressing plate 321 installed on the cutting head 31, when the electric push rod 3 moves downward and the cutting head 31 contacts the surface of the woolen overcoat for cutting, the pressing plate 321 also contacts the surface of the woolen overcoat and generates a certain pressing effect, so as to smooth and press the vicinity of the part being cut by the cutting head 31 to a certain extent.

[0060] When fixing the woolen overcoat by using the elasticity of the snap fastener 4 itself, the friction points 42 provided on the surface of the snap fastener 4 can increase the friction force between the snap fastener 4 and the woolen overcoat as much as possible without damaging the surface of the woolen overcoat, improving the fixing effect of the snap fastener 4 on the woolen overcoat. At the same time, since the fixing column 41 itself has magnetism, after the staff inserts the fixing column 41 into the through hole 13 on the placement plate 1, the fixing column 41 can stay stably in the through hole 13 under the action of its own magnetic force;

[0061] At the same time, by placing the fixing block 5 on the woolen overcoat and using the mutual attraction between the fixing block 5 itself and the placement plate 1 due to magnetism, the fixing block 5 presses and fixes the position where it is located on the woolen overcoat. At the same time, by placing the fixing block 5 near the cutting area on the woolen overcoat, the cutting area on the woolen overcoat is in a relatively taut state;

[0062] At the same time, since the through holes 13 on the placement plate 1 are evenly arranged and there are multiple of them, by providing protrusions 51 on the fixing block 5 that match the size of the through holes 13, after the staff places the fixing block 5 on the woolen overcoat, under the action of the magnetic attraction between the fixing block 5 and the placement plate 1, the protrusions 51 on the fixing block 5 will press down the area on the woolen overcoat corresponding to the through holes 13, so that part of the area where the woolen overcoat is close to the placement plate 1 sinks into the through holes 13, thereby improving the fixing effect of the fixing block 5 on the woolen overcoat;

[0063] At the same time, by installing guide rollers 322 on the pressing plate 321 and making the guide rollers 322 rotate relative to the pressing plate 321, it is convenient for the pressing plate 321 to move on the surface of the woolen overcoat, reducing the friction force between the pressing plate 321 and the woolen overcoat;

[0064] By installing a suction pipe 6 on the cutting head 31, an external negative pressure fan is used to collect the fluff and dust generated during the cutting process;

[0065] By providing a brush 62 on the lower end surface of the suction pipe 6, the brush 62 is used to close the gap between the suction pipe 6 and the woolen overcoat to a certain extent, improving the negative pressure suction force of the notch of the brush 62 facing the cutting head 31 direction, so as to collect the fluff, waste materials and dust generated during the cutting process as much as possible. At the same time, by the sweeping and brushing of the brush 62 on the surface of the woolen overcoat, the number of fluff, waste materials and dust attached to the surface of the woolen overcoat is reduced.
