Description

Technical Field

[0001] This utility model belongs to the field of fabric bonding for underwear back buckle straps, specifically relating to an automatic heat press machine for bonding fabric for underwear back buckle straps. Background Technology

[0002] Underwear generally refers to women's intimate apparel. Underwear typically uses back clasp or pullover styles. Most women choose back clasp bras when purchasing them. However, the manufacturing process of back clasp bras requires an automatic heat press machine to bond the back clasp fabric together, achieving a seamless finish. Existing automatic heat press machines for bonding back clasp fabric work by automatically feeding the fabric to be heat-bonded using a feeding and receiving assembly. Then, a heat press plate presses the fabric against a receiving plate, bonding the fabric to the surface of the receiving plate.

[0003] For example, in the Chinese utility model patent CN217516353U, entitled "An Automatic Heat Press Machine for Bonding Fabric for Bra Back Buckle Straps," a support component, a heat pressing component, a material receiving component, and a material feeding component are included, as well as a groove and a spring-loaded component. The above-mentioned prior art solves the problem that the fabric cooling speed is too fast, resulting in some parts of the fabric not being bonded and requiring rework. It saves time and improves work efficiency. It can also prevent the fabric from being snagged by the edges of the pressure plate during conveying. However, it does not have a cooling component. In the prior art, air cooling is usually used to cool the fabric. After air cooling and heat pressing, the high temperature of the fabric cools down slowly, the back buckle strap bonding area is unstable and prone to displacement, and the fabric is kept at a high temperature for a long time, resulting in local wrinkling and fiber damage, which slows down the pace of subsequent processes. Therefore, there is a need for an automatic heat press machine for bonding fabric for bra back buckle straps. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic heat press machine for bonding fabric for underwear back buckle straps, which has a simple structure and reasonable design, in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] An automatic ironing machine for bonding fabric to back clasp straps in underwear includes a fixed base, a body fixedly mounted on the top of the fixed base, a lower pressure plate fixedly connected to the top of the body, a support frame fixedly connected to the top of the body, a fixed frame fixedly connected to the upper part of the support frame, a cylinder fixedly mounted on the top of the fixed frame, a connecting plate fixedly connected to the drive end of the cylinder after sliding through the fixed frame, two guide rods sliding through the fixed frame fixedly connected to the top of the connecting plate, a pressure plate fixing assembly detachably connected to the outer side of the connecting plate, and a cooling assembly fixedly mounted on the top of the fixed base.

[0007] As a further optimization of this utility model, a first fixed bracket is fixedly connected to the top of the fixed base, an installation roller is rotatably connected to the outer side of the first fixed bracket, and two second fixed brackets are symmetrically fixedly connected to one side of the machine body, with guide rollers rotatably connected to the inner sides of the two second fixed brackets.

[0008] As a further optimization of this utility model, the pressure plate fixing assembly includes a slide rail detachably connected to the outside of the connecting plate. Fixing holes are provided on both sides of the middle part of the slide rail, and fixing holes are provided on both sides of the inner wall of the connecting plate. A pin is slidably passed through the inner side of the slide rail, and the outer side of the pin is inserted into the inner side of the fixing hole.

[0009] As a further optimization of this utility model, a fixing plate is fixedly connected to the bottom of the slide rail, and multiple connecting rods are slidably arranged on the outer side of the fixing plate. The bottom of the multiple connecting rods is fixedly connected to an upper pressure plate, and a buffer spring is sleeved on the outer side of the connecting rods, abutting against the fixing plate and the upper pressure plate.

[0010] As a further optimization of this utility model, the cooling assembly includes a U-shaped mounting bracket fixedly connected to the top of the fixed base. A water-cooled roller one is rotatably connected to the inner side of the U-shaped mounting bracket. Slide plates are slidably connected to the inner walls of both sides of the U-shaped mounting bracket. A mounting plate is fixedly connected between the two slide plates. Multiple fans are fixedly connected to the inner side of the mounting plate. A water-cooled roller two is rotatably connected between the two slide plates. A water pump is fixedly connected to the top of the fixed base. The input ends of the water-cooled roller one and water-cooled roller two are connected to the output end of the water pump through pipes. The input end of the water pump is connected to the output end of the heat exchanger through pipes. The output ends of the water-cooled roller one and water-cooled roller two are connected to the input end of the heat exchanger through pipes.

[0011] As a further optimization of this utility model, the inner walls of both sides of the U-shaped mounting bracket are provided with sliding grooves, the outer side of the sliding plate is slidably connected to the inner side of the sliding groove, and the inner side of the U-shaped mounting bracket is rotatably connected to a screw threaded through the sliding groove.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. In this utility model, the upper fan provides initial cooling after hot pressing. When the fabric passes through two water-cooled rollers, the coolant inside the rollers is driven by a water pump and cooled by a heat exchanger. The operator can adjust the distance between the two rollers by turning the screw handle to control the pressing force. It has a dual cooling effect. The distance can be adjusted to suit the fabric, maintain contact and improve efficiency, and reduce high temperature retention to avoid burns to the staff.

[0014] 2. When disassembling and assembling the upper pressure plate of this utility model, the operator can pull out the pin and slide it out along the connecting plate to disassemble it. The installation is the same. During operation, the cylinder drives the upper pressure plate to press down, which together with the lower pressure plate presses the fabric. At the same time, the upper pressure plate drives the connecting rod to slide up. The buffer spring plays a buffering role. The device is easy to disassemble and assemble when maintaining or replacing different models of upper pressure plates. During processing, the compression of the buffer spring can prevent the pressure of the upper pressure plate from being too high, thereby protecting the components below it and ensuring that the fabric is fully ironed.

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example 1

[0023] like Figure 1 , Figure 2As shown, an automatic heat press machine for bonding fabric for bra back buckle straps includes a fixed base 1, which supports all components of the machine to ensure stable operation. A body 2 is fixedly mounted on the top of the fixed base 1, providing the mounting base for the fabric heat press. A lower pressure plate 3 is fixedly connected to the top of the body 2, which performs heat pressing to achieve fabric bonding. A support frame 4 is fixedly connected to the top of the body 2, providing stable support. A fixed frame 5 is fixedly connected to the upper part of the support frame 4, which can fix a cylinder 6 to ensure stable driving. The cylinder 6 is fixedly mounted on the top of the fixed frame 5. In this invention, the cylinder 6 is an Airtac SE40×80-S, which can be replaced according to actual needs. The cylinder 6 serves as the downward pressure drive source.

[0024] like Figure 1 , Figure 5 As shown, the drive end of cylinder 6 slides through the fixed frame 5 and is fixedly connected to a connecting plate 7. The connecting plate 7 can connect the guide rod 8 and the pressure plate fixing assembly 9 to drive the upper pressure plate 905 to move synchronously. Two guide rods 8 that slide through the fixed frame 5 are fixedly connected to the top of the connecting plate 7. The guide rods 8 can guide the connecting plate 7 when it moves up and down to prevent the connecting plate 7 from shifting. A fixed bracket 10 is fixedly connected to the top of the fixed seat 1. The fixed bracket 10 can support the mounting roller 11 to ensure the stable rotation of the mounting roller 11. The mounting roller 11 is rotatably connected to the outside of the fixed bracket 10. The mounting roller 11 can be installed with the processing roll to facilitate the unfolding and conveying of the fabric. Two fixed brackets 2 13 are symmetrically fixedly connected to one side of the machine body 2. The fixed brackets 2 13 can support the guide roller 14 to ensure the installation position of the guide roller 14. The guide roller 14 is rotatably connected to the inner side of the two fixed brackets 2 13. The guide roller 14 can guide the direction of fabric movement so that the fabric can smoothly reach the upper surface of the lower pressure plate 3.

[0025] like Figure 4 , Figure 5 As shown, a pressure plate fixing assembly 9 is detachably connected to the outer side of the connecting plate 7. The pressure plate fixing assembly 9 can fix the upper pressure plate 905 and facilitate the installation and removal of the upper pressure plate 905. The pressure plate fixing assembly 9 includes a slide rail 901, which provides an installation and sliding channel for the pin 902 and connects to the fixing plate 903. The inner side of the slide rail 901 is detachably connected to the outer side of the connecting plate 7. Fixing holes are opened on both sides of the middle part of the slide rail 901. The fixing holes can provide a insertion position for the pin 902 to fix the slide rail 901 and the connecting plate 7. Fixing holes are opened on both sides of the inner wall of the connecting plate 7. The fixing holes can cooperate with the fixing holes on the slide rail 901 to allow the pin 902 to be inserted. The inner side of the slide rail 901 slides through the pin 902. The pin 902 can fix the slide rail 901 on the connecting plate 7. When disassembling, it can be pulled out to separate the two. The outer side of the pin 902 is inserted into the inner side of the fixing hole.

[0026] like Figure 4, Figure 5 As shown, a fixed plate 903 is fixedly connected to the bottom of the slide rail 901. The fixed plate 903 provides sliding support for the connecting rod 904 and also bears one end of the buffer spring 906. Multiple connecting rods 904 are slidably arranged on the outer side of the fixed plate 903. The connecting rods 904 can drive the upper pressure plate 905 to move up and down while limiting the offset direction of the upper pressure plate 905. The bottom of the multiple connecting rods 904 is fixedly connected to the upper pressure plate 905. The upper pressure plate 905 can be pressed down by the cylinder 6 and cooperate with the lower pressure plate 3 to perform heat pressing on the fabric. A buffer spring 906 is sleeved on the outer side of the connecting rod 904. The buffer spring 906 can provide buffer when the cylinder 6 drives the upper pressure plate 905 to press down to prevent excessive pressure from damaging the parts and avoid the problem of insufficient heating due to short contact time between the upper pressure plate 905 and the fabric. The buffer spring 906 abuts between the fixed plate 903 and the upper pressure plate 905.

[0027] like Figure 1 , Figure 2 , Figure 3 As shown, a cooling assembly 12 is fixedly installed on the top of the fixed base 1. The cooling assembly 12 can cool the fabric after hot pressing to improve cooling efficiency. The cooling assembly 12 includes a U-shaped mounting bracket 1201, which supports components such as the water-cooled roller 1202 and the sliding plate 1204 to provide a mounting base for the cooling components. The bottom of the U-shaped mounting bracket 1201 is fixedly connected to the top of the fixed base 1. The water-cooled roller 1202 is rotatably connected to the inner side of the U-shaped mounting bracket 1201. The water-cooled roller 1202 cools the fabric by removing heat through its internal coolant. Sliding plates 1204 are slidably connected to the inner walls of both sides of the U-shaped mounting bracket 1201. 204 can drive the mounting plate 1205 to move up and down to adjust the position of the fan 1206 to adapt to different cooling needs. The mounting plate 1205 is fixedly connected between the two sliding plates 1204. The mounting plate 1205 can fix multiple fans 1206 to ensure the installation stability of the fans 1206. Multiple fans 1206 are fixedly connected to the inner side of the mounting plate 1205. The fans 1206 can perform preliminary cooling on the hot-pressed fabric to reduce the high-temperature retention time of the fabric. A second water-cooling roller 1207 is rotatably connected between the two sliding plates 1204. The first water-cooling roller 1202 can cooperate with the second water-cooling roller 1207 to clamp the fabric and remove the heat of the fabric through the internal coolant to achieve cooling.

[0028] like Figure 2 , Figure 3As shown, a water pump 1208 is fixedly connected to the top of the fixed base 1. The water pump 1208 drives the coolant to circulate between the first water-cooled roller 1202, the second water-cooled roller 1207, and the heat exchanger 1209 to ensure the cooling effect. The input ends of the first water-cooled roller 1202 and the second water-cooled roller 1207 are connected to the output end of the water pump 1208 through pipes. The pipes provide a flow channel for the coolant to ensure that the coolant is delivered from the water pump 1208 to the first water-cooled roller 1202 and the second water-cooled roller 1207. The input end of the water pump 1208 is connected to the output end of the water pump 1208 through... The pipe is connected to the output end of the heat exchanger 1209. The pipe provides a flow channel for the coolant, ensuring that the cooled coolant is transported from the heat exchanger 1209 to the water pump 1208. The output ends of the water-cooled roller 1202 and the water-cooled roller 2 1207 are connected to the input end of the heat exchanger 1209 through the pipe. The pipe provides a flow channel for the coolant, ensuring that the cooled coolant, after absorbing heat, is transported from the water-cooled roller to the heat exchanger 1209. Heat exchange between the hot and cold fluids is achieved through the metal tube wall inside the heat exchanger 1209, and the coolant is cooled down.

[0029] like Figure 2 , Figure 3 As shown, the inner walls of both sides of the U-shaped mounting bracket 1201 are provided with sliding grooves 1203. The sliding grooves 1203 can provide a sliding track for the slide plate 1204 to slide stably up and down. The outer side of the slide plate 1204 is slidably connected to the inner side of the sliding groove 1203. The inner side of the U-shaped mounting bracket 1201 is rotatably connected with a lead screw 1210. The lead screw 1210 can drive the slide plate 1204 to move by rotating, thereby adjusting the distance between the first water-cooled roller 1202 and the second water-cooled roller 1207 to control the clamping force. The outer thread of the lead screw 1210 passes through the outer side of the sliding groove 1203.

[0030] It should be noted that this automatic heat press machine for bonding fabric for bra back clasp straps involves mounting the processing roll onto roller 11 and fixing the other end of the roll to the collecting roller at the other end of the device. The fabric runs along the bottom of guide roller 14, the upper surface of lower pressure plate 3, and between water-cooled roller 1202 and water-cooled roller 2207. The collecting roller is rotated by a motor. When cylinder 6 pushes upper pressure plate 905 downward, the collecting roller stops rotating. After the fabric is heat-pressed by upper pressure plate 905 and lower pressure plate 3, it is initially cooled by multiple fans 1206 above it. As the fabric passes between water-cooled roller 1202 and water-cooled roller 2207, the heat is cooled by water. The coolant inside roller 1202 and water-cooled roller 2207 is carried away. The coolant inside is driven by water pump 1208 and cooled by heat exchanger 1209, forming a circulation. The operator turns the handle on the lead screw 1210 to control the distance between water-cooled roller 1202 and water-cooled roller 2207, thereby controlling the clamping force between them and ensuring that the fabric is in full contact with the water-cooled rollers. The fan 1206 and the circulating water cooling provide dual cooling effect. The distance between the water-cooled rollers can be adjusted to adapt to different types of fabrics and control the clamping force to ensure that the fabric is in full contact, improve cooling efficiency, reduce the high temperature retention of materials during processing, and avoid the risk of burns to the workers at the collection roller.

[0031] When the upper pressure plate 905 needs to be disassembled, the operator pulls out the two pins 902 and slides them along the slide rail 901 along the connecting plate 7 to remove the upper pressure plate 905. The same applies during installation. When the cylinder 6 drives the upper pressure plate 905 to press down, the upper pressure plate 905 and the lower pressure plate 3 press the fabric together. The upper pressure plate 905 drives the connecting rod 904 to slide upward, and the buffer spring 906 buffers it. The device is easy to disassemble and assemble when maintaining or replacing different models of upper pressure plates 905. During processing, the compression of the buffer spring 906 effectively prevents the pressure of the upper pressure plate 905 from being too high, protecting the components below it and avoiding short contact time of the fabric during ironing.

[0032] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
