Description

Technical Field

[0001] The present invention relates to the technical field of trouser loop machines, and particularly refers to an integrated ironing and cutting trouser loop machine. Background Art

[0002] Trouser loops are usually sewn on the waist of trousers for threading belts. To increase the firmness of the trouser loops, they are generally made by sewing two layers or multiple layers of fabric together. The equipment used to make trouser loops is called a trouser loop machine. Generally, when making trouser loops in a garment factory, an ordinary special sewing machine for trouser loops is used to sew the blank tapes of the trouser loops. Then, the blank tapes are cut into finished trouser loops one by one by manual measurement, and then the trouser loops are sewn onto the waistband by other sewing equipment.

[0003] Now there is a kind of ironing table device on the market, with the patent number 2018218295415, which can combine the sewing and ironing of trouser loops into one process. However, subsequent manual measurement and cutting into specific lengths are still required, seriously affecting production efficiency, and at the same time, the accuracy of manual cutting is relatively low. Summary of the Invention

[0004] The purpose of the present invention is to provide an integrated ironing and cutting trouser loop machine. By setting a cutting device behind the ironing device and using a detection device to move synchronously, the control system calculates the cutting length and controls the subsequent cutting device to accurately cut the trouser loop strips, solving the problems of low efficiency and low accuracy of manual cutting in the existing design.

[0050] A positioning notch is provided on the side of the ironing board, a positioning column is installed on the feeding mechanism, and the end of the positioning column is placed in the positioning notch and moves in the positioning notch to make the feeding mechanism parallel to the ironing board.

[0051] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects:

[0052] 1. The design of the present invention is to combine the cutting device and the ironing device with the main body of the trouser loop machine to form an integrated ironing and cutting trouser loop machine. Through the control system, the sewing, ironing and cutting of the trouser loops can be carried out simultaneously, and the original three processes are integrated into one process, solving the problems of low efficiency and low precision of the existing manual cutting;

[0053] At the same time, the detection device can make the ironing device and the cutting device move synchronously with the main body of the trouser loop machine, so that the trouser loops of a specific length can be cut by calculating the number of sewing stitches, thereby ensuring the accuracy of cutting.

[0054] 2. The crotch position sensing mechanism of the present invention extends the length of the crotch position of the trouser loop by allowing the crotch position of the trouser loop to pass between the active roller and the driven roller, and the sensor detects the change in distance, thereby avoiding the situation where the trouser loop length does not meet the requirements after the trouser loop is subsequently cut off, thereby reducing waste.

[0055] 3. The knife adjustment mechanism designed in the present invention adjusts the force applied by the spring to the second baffle plate by rotating the spring bolt, pushes the first baffle plate to support the knife seat, adjusts the compactness between the fixed knife and the movable knife, ensures that the cutting device can cut the trouser loops normally, ensures the flatness of the cutting plane, and avoids the occurrence of thread connection.

[0056] 4. The pressure plate provided in the present invention uses a reset spring to make the pressure plate lower than the blade of the moving knife. When cutting, the pressure plate first presses the trouser loops, and then the moving knife cooperates with the fixed knife to cut the trouser loops, thereby ensuring the accuracy of the cutting length and the flatness of the cutting surface.

[0057] 5. The present invention opens a steam chamber in the ironing board, uses a steam generating mechanism to provide steam for the steam chamber, and uses steam to assist the ironing board in ironing the trouser loops. This can achieve a better ironing and shaping effect, and at the same time avoid the situation where the ironing board temperature is too high and causes damage to the trouser loops, thereby protecting the trouser loops and the feeding mechanism.

[0058] 6. The rib provided in the steam cavity of the present invention can block the condensed water, reduce the amount of water flowing out from the steam holes, avoid the corrosion and rust of the equipment due to excessive condensed water, and ensure the service life.

[0059] 7. The steam water filtering box provided in the present invention separates the steam and water vapor of the steam through the second steam hole, reduces the moisture in the steam, reduces the formation amount of dirt in the pipeline and the ironing board, and ensures the steam heat.

[0060] 8. The driving member of the present invention drives the feeding mechanism to move up and down, so that the feeding mechanism approaches and then moves away from the ironing mechanism. When the main body of the trouser loop machine is not working, the feeding mechanism is moved away from the ironing mechanism to prevent the damage of the feeding mechanism and the trouser loop.

[0076] The following further elaborates on the detailed implementation manners of the present invention with reference to the accompanying drawings

[0077] As Figure 1 and Figure 2 shown, a combined ironing and cutting trouser loop machine includes: a trouser loop machine main body 100, an ironing device 200, a cutting device 300, and a detection device 400. A detector 102 is provided inside the detection device 400. The cutting device 300 includes a fixed seat 301, a fixed knife 303, a moving knife 302, a stock position sensing mechanism 305, and a knife adjusting mechanism 309. The stock position sensing mechanism 305 includes: a driving roller 306, a driven roller 307, and an inductor 308. The knife adjusting mechanism 309 includes: a knife seat 310, a first retaining piece 311, a second retaining piece 312, and a spring bolt 313

[0078] The combined ironing and cutting trouser loop machine is also equipped with a control system, which is programmed by technicians according to the actual situation and movement requirements. It mainly controls the coordinated operation of the trouser loop machine main body 100, the ironing device 200, and the cutting device 300 through the data or switches fed back by the corresponding sensors. Since the control system is not the key point of protection, it will not be elaborated

[0079] A panel 101 is provided on the main body 100 of the trouser loop machine. The ironing device 200 is installed and fixed on the panel 101 below the machine head. The cutting device 300 is installed on one side close to the discharge port of the ironing device 200. One end of the detection device 400 is connected to the transmission shaft 404 of the main body 100 of the trouser loop machine, and the other end is respectively connected to the ironing device 200 and the cutting device 300. When the main body 100 of the trouser loop machine works, through the detection device 400, the ironing device 200 and the cutting device 300 also move synchronously.

[0080] After the sewn trouser loop strip enters the ironing device 200 for ironing and shaping first, it then moves out from the discharge port of the ironing device 200 and enters the cutting device 300 for cutting, thus completing the processes of sewing - ironing - cutting of the trouser loop.

[0081] The installation method of the cutting device 300 is as follows:

[0082] As Figures 3 - 6 shown, the fixed seat 301 is installed on the panel 101 on one side of the discharge port of the ironing device 200. The fixed knife 303 is installed on the fixed seat 301, and the blade part faces upward. The moving knife 302 is movably installed on the fixed seat 301. A driver 304 is installed on the fixed seat 301. The driver 304 can be a cylinder or an oil cylinder. The driver 304 is used to drive the moving knife 302 to move up and down to cooperate with the fixed knife 303 to cut the trouser loop.

[0083] A detector 102 is installed on the panel 101. The detector 102 is mainly used to detect the number of rotation turns of the rotating shaft 401 in the detection device 400 and transmit the detected data to the control system. One turn of the rotating shaft 401 means that the main body 100 of the trouser loop machine sews one stitch.

[0084] By detecting the number of rotation turns of the rotating shaft 401 to calculate the number of stitches of the trouser loop sewn, and using the number of stitches to calculate the length of the trouser loop, so as to ensure that the cutting device 300 can accurately cut the trouser loop of a specific length, making the sewing - ironing - cutting of the trouser loop form a process, improving the speed and ensuring the cutting accuracy.

[0085] The design of the present invention is to combine the cutting device 300 and the ironing device 200 onto the main body 100 of the trouser loop machine to form an integrated ironing and cutting main body 100 of the trouser loop machine, realizing that the sewing - ironing - cutting of the trouser loop can be carried out simultaneously, integrating the original three processes into one process, and solving the problems of low efficiency and low accuracy of the existing manual cutting;

[0086] At the same time, the detection device 400 can make the ironing device 200 and the cutting device 300 move synchronously with the main body 100 of the trouser loop machine, so that it can be realized that the trouser loop of a specific length can be cut by calculating the number of sewing stitches, ensuring the cutting accuracy.

[0087] During the process of sewing the trouser loops, due to the sewing of the joints of two pieces of fabric, a stockinette will be formed. If there is a stockinette on the cut trouser loop, then this trouser loop cannot be used. Therefore, in order to reduce the situation where the trouser loop cannot be used due to the stockinette and cause waste, the stockinette sensing mechanism 305 is installed on the fixed seat 301.

[0088] As Figure 3 and Figure 5 shown, the stockinette sensing mechanism 305 includes: a driving roller 306, a driven roller 307 and a sensor 308; the driving roller 306 is installed inside the fixed seat 301, and the side wall is higher than the plane of the fixed seat 301. A support arm 319 is hinged on each side of the fixed seat 301. The driven roller 307 is installed at the end of the support arm 319 through a connecting shaft. The driven roller 307 can rotate around the hinge point of the support arm 319. The outer surface of the driven roller 307 abuts against the outer wall of the driving roller 306. The end of the driving roller 306 is connected to the detection device 400 through a synchronous pulley.

[0089] Or a movable groove is opened on the fixed seat 301. The end of the connecting shaft of the driven roller 307 is placed in the movable groove, and a compression spring is connected to the end of the connecting shaft to pull the connecting shaft downward so that the outer wall of the driven roller 307 closely adheres to the driving roller 306.

[0090] The sensor 308 is vertically installed above the driven roller 307 and is used to detect the distance from the end of the sensor 308 to the connecting shaft. The trouser loop is clamped between the driving roller 306 and the driven roller 307, and the driving roller 306 rotates to achieve the purpose of conveying the trouser loop;

[0091] When the stockinette moves between the driving roller 306 and the driven roller 307, the driven roller 307 is lifted, that is, the connecting shaft is lifted, and the distance from the end of the sensor 308 to the driven roller 307 changes. The sensor 308 transmits this signal to the control system. If the calculated number of stitches has not reached the standard number of stitches, the control system recalculates the number of stitches, and then cuts after reaching the standard number of stitches. (For example, the standard number of stitches is 10 stitches, and 8 stitches have been calculated. When the stockinette is detected, continue to travel a specific number of stitches. This specific number of stitches can be selected according to the actual situation. In this embodiment, two stitches are taken as an example, that is, continue to travel two more stitches and then cut, and then resume the original standard 10-stitches cutting plan.

[0092] The number of these two stitches is mainly to ensure that the stockinette can be completely removed to avoid the residue of the stockinette after cutting.

[0093] Such a design is used to reduce waste.

[0094] To avoid the influence of irregular trouser loops on the sensor 308, compression springs are provided on both sides of the fixed seat 301. The compression springs are used to pull down the support arm 319 downward, applying a downward force to the driven roller 307 to clamp the fabric, preventing the driven roller 307 from moving due to the irregularity of the trouser loops and accidentally touching the sensor 308, which would affect the detection and result in incorrect cutting.

[0095] A material box 321 is also installed under the fixed seat for collecting the trouser loops after cutting.

[0096] The installation of the tool adjustment mechanism 309 is as follows.

[0097] As Figure 5 shown, sliding grooves 320 are formed on both side edges of the fixed seat 301. The edge of the tool holder 310 is stuck in the sliding grooves 320, enabling the tool holder 310 to only move along the sliding grooves 320. The moving blade 302 is installed at the lower end of the tool holder 310; a first retaining piece 311 is vertically installed in the sliding grooves 320, and its end face abuts against the end face of the tool holder 310; a second retaining piece 312 is placed outside the fixed seat 301 with a gap left between it and the fixed seat 301. The second retaining piece 312 is connected to the first retaining piece 311 by a pin shaft passing through the fixed seat 301. The spring bolt 313 is threadedly connected to the fixed seat 301, and the spring on the spring bolt 313 abuts against the second retaining piece 312.

[0098] Rotate the spring bolt 313 to increase the force of the spring abutting against the second retaining piece 312, thereby increasing the force of the first retaining piece 311 against the tool holder 310, ensuring the tightness between the moving blade 302 and the fixed blade 303 during cutting.

[0099] With such a design, it is ensured that the cutting device 300 can cut the trouser loops normally, ensuring the flatness of the cutting plane and avoiding the situation of filament connection.

[0100] As Figure 4 shown, to avoid the situation where the cutting edges of the moving blade 302 and the fixed blade 303 abut against each other, a convex edge 318 is formed at one end of the cutting edge of the moving blade 302. The outer wall of the convex edge 318 abuts against the side wall of the fixed blade 303, and the convex edge 318 slides on the side wall of the fixed blade 303.

[0101] The convex edge 318 is used to ensure that the cutting edges of the two do not cut each other, ensuring the cutting effect and protecting the fixed blade 303 and the moving blade 302.

[0102] At the same time, mounting blocks 314 are provided on both sides of the knife seat 310, and guide columns 315 are movably installed on the mounting blocks 314. A pressure plate 316 is installed at the lower end of the guide column 315. The two ends of the pressure plate 316 are respectively connected to the two guide columns 315. A return spring 317 is provided between the pressure plate 316 and the mounting block 314 to support the pressure plate 316 so that the pressure plate 316 is lower than the blade of the movable knife 302.

[0103] The pressure plate 316 provided in the present invention is used to make the pressure plate 316 lower than the blade of the movable knife 302 through the reset spring 317. When cutting, the pressure plate 316 first presses the trouser loops, and then the movable knife 302 cooperates with the fixed knife 303 to cut the trouser loops, thereby ensuring the accuracy of the cutting length and the flatness of the cutting surface.

[0104] A limit piece 322 can be installed on the upper end of the guide column 315. The limit piece 322 can be a pin or a limit block. The limit piece 322 abuts against the end surface of the mounting block 314 to play a blocking role, ensuring that the guide column 315 will not separate from the mounting block.

[0105] A mounting bar is also installed at the upper end of the fixing seat 301, and the driver 304 is installed at the lower end of the mounting bar. At the same time, both ends of the mounting bar cover the part of the end of the slide slot 320 to limit the baffle 1 311 from moving out of the slide slot 320 to avoid loss.

[0106] The installation structure of the ironing device 200 is as follows.

[0107] like Figure 7 As shown, the ironing device 200 comprises: a base 220, an ironing mechanism 201 and a feeding mechanism 202; the ironing mechanism 201 comprises: an ironing board 203 and a steam generator 207;

[0108] The base 220 is installed on the panel 101, and a driving member 217 is installed under the panel 101. A U-shaped lifting plate 216 is installed at the output end of the driving member 217. The lifting plate 216 passes through the panel 101 and the base 220 and is connected to the feeding mechanism 202. The ironing plate 203 is installed above the feeding mechanism 202. The feeding mechanism 202 is driven up and down by the driving member 217, and the ironing action is realized in coordination with the start and stop of the trouser loop machine body 100.

[0109] When the trouser loop machine body 100 is working, the control system controls the driving member 217 to make the feeding mechanism 202 close to the ironing mechanism 201;

[0110] When the trouser loop machine body 100 stops working, the control system controls the driving member 217 to move the feeding mechanism 202 away from the ironing mechanism 201.

[0111] The driving member 217 of the present invention drives the feeding mechanism 202 to move up and down, so that the feeding mechanism 202 approaches and then moves away from the ironing mechanism 201. When the trouser loop machine main body 100 is not working, the feeding mechanism 202 is moved away from the ironing mechanism 201 to prevent damage to the feeding mechanism 202 and the trouser loops.

[0112] Meanwhile, a positioning notch 218 is formed on the side surface of the ironing board 203, a positioning post 219 is installed on the feeding mechanism 202, and the end of the positioning post 219 is placed in the positioning notch 218 and moves within the positioning notch 218.

[0113] This sub-structure is used to ensure the horizontality of the feeding mechanism 202, making the feeding mechanism 202 parallel to the ironing board 203.

[0114] The feeding mechanism 202 includes a feeding frame, conveying wheels are installed at both ends of the feeding frame, a conveyor belt is sleeved on the conveying wheels, and the conveying wheels are connected to a transmission device.

[0115] As Figure 8 shown, a heating rod is installed inside the ironing board 203 to provide heat. Meanwhile, a steam cavity 204 is formed inside the ironing board 203. Air inlet holes 221 and drain holes 208 are respectively formed at both ends of the steam cavity 204. The air inlet hole 221 is connected to a steam generator 207 through a pipeline, and the drain hole 208 is connected to a drain pipe.

[0116] A rib 206 is formed in the middle of the steam cavity 204, and a plurality of first steam holes 205 are neatly formed on the rib 206. The ends of the first steam holes 205 are opened on the ironing surface.

[0117] Steam enters the steam cavity 204 through the steam generator 207, and then sprays out from the first steam holes 205, cooperating with the heated ironing board 203 to iron and shape the trouser loops.

[0118] In the present invention, a steam cavity 204 is formed inside the ironing board 203, and a steam generating mechanism is used to provide steam for the steam cavity 204. The steam is used to assist the ironing board 203 to iron the trouser loops, so that the ironing and shaping effect can be better, and at the same time, the situation that the ironing board 203 has too high a temperature and damages the trouser loops can be avoided, protecting the trouser loops and the feeding mechanism 202.

[0119] Meanwhile, the rib 206 provided in the steam cavity 204 can block the condensed water, reduce the amount of water flowing out from the first steam holes 205, avoid the situation that the equipment corrodes and rusts due to too much condensed water, and ensure the service life.

[0120] A steam water filtering box 209 is also provided between the steam generating mechanism and the ironing board 203. The steam first enters the steam water filtering box 209 and then enters the steam cavity 204.

[0121] AsFigure 9 As shown, the steam water filter box 209 includes:

[0122] A box body 210, which is provided with an air inlet 211 and a drain outlet 212. The air inlet 211 is communicated with the steam generator 207, and the drain outlet 212 is used for discharging the condensed water in the box body 210;

[0123] A water filter cartridge 213, which is placed in the box body 210, and an air outlet 214 is provided on the side wall of the water filter cartridge 213, and the end of the air outlet 214 penetrates out of the box body 210;

[0124] The side wall of the water filter cartridge 213 is provided with a second steam hole 215. The steam first enters the box body 210, and then the steam is subjected to water-vapor separation through the second steam hole 215. The steam after water-vapor separation enters the steam cavity 204.

[0125] The diameter of the second steam hole 215 is very small. When the steam passes through the second steam hole 215, the moisture in the steam will be blocked and then discharged through the drain hole 208.

[0126] The steam water filter box 209 provided by the present invention performs water-vapor separation on the steam through the second steam hole 215, reduces the moisture in the steam, reduces the formation amount of dirt in the pipeline and the ironing board 203, and ensures the steam heat.

[0127] At the same time, reducing the moisture can reduce the heat loss in the steam and reduce the possibility of corrosion, and ensure the service life.
