Description

Technical Field

[0001] The present application relates to the technical field of lining equipment, and in particular to a center folded edge belt production equipment and production method. Background Art

[0002] In clothing manufacturing, the production of strips such as shoulder straps, belts, cuffs and other products usually adopts traditional cutting and sewing and ultrasonic processes. These processes are prone to edge bursting during use, the production process is complex, the production capacity is slow, and the yield rate is low, which affects the quality and appearance of the product.

[0003] To address the edge bursting problem, the fabric is typically treated with additional processing during production, such as hemming and overlocking. The overlocked edge is then manually folded inward toward the center, followed by a press machine to seal the folding mark. Finally, the fabric is secured, completing the folding process and producing the tape strip.

[0004] Currently, lining machines consist of a conveyor belt, a heater, and rollers. The conveyor belt transports the initially folded tape, which is then heated by the heater before being rolled by the rollers. However, during production, because the tape width varies, the heater generates heat in the unused outer portion when processing products of varying widths. This heat cannot directly reach the tape, resulting in energy waste. This drawback is particularly pronounced in production lines where the tape width must be frequently changed. Therefore, an effective solution to reduce heat waste is urgently needed. Summary of the Invention

[0005] In order to reduce heat waste, the present application provides a center folded edge belt production device and production method.

[0006] In a first aspect, the present application provides a center hem tape production device, which adopts the following technical solution:

[0008] A machine body, wherein the machine body is provided with a conveyor belt for circular rotation, the machine body is rotatably connected to a rolling roller, and a pressing space is formed between the rolling roller and the conveyor belt;

[0009] a heating unit, disposed on the machine body, with a heating space formed between the heating unit and the conveyor belt;

[0010] The heating part includes a supporting column and a heating tube, wherein the supporting column is arranged on the body and has a supporting slot formed therein, and the heating tube is arranged on the supporting column and passes through the supporting slot;

[0011] The bearing columns are symmetrically and slidably connected with partitions, and the partitions block the notches of the bearing slots;

[0012] The supporting columns are provided with a control member, and the control member controls the relative approach or distance between the partitions.

[0013] The body is provided with an observation window facing the bearing column;

[0014] A preheating portion, disposed on a side wall of the supporting column;

[0015] The preheating part includes a support column and a preheating roller, wherein the support column is arranged on a side of the bearing column away from the laminating roller, the preheating roller is rotatably connected to the support column, and a preheating space is formed between the preheating roller and the conveyor belt;

[0016] A heat transfer component is connected to the preheating part and the heating part, and the heat transfer component transfers the heat emitted by the heating pipe facing the partition to the preheating part.

[0017] By adopting this technical solution, the pressed space formed by the conveyor belt and the laminating roller ensures the stability of the belt during transmission. The heating space between the heating unit and the conveyor belt evenly heats the belt through the heating tube, improving heating efficiency and effectiveness. The design of the sliding partitions and control components on the supporting column allows the size of the heating space to be adjusted to meet the production needs of belts of different specifications. Furthermore, the provision of a preheating unit further increases the temperature of the belt before entering the heating space, reducing the overall heating time and improving production efficiency. The heat transfer component effectively transfers the heat generated by the heating tube to the preheating unit, achieving efficient heat utilization.

[0018] Optionally, the heat transfer component includes a heating water bag, a water pipe and a heat transfer water bag;

[0019] The heating water bag is sheathed around the outer circumference of the heating pipe, the heat transfer bag is arranged in the preheating roller, the water pipe corresponds to the heating water bag one by one, and the water pipe connects the heating water bag and the heat transfer bag.

[0020] With this technical solution, a heating water bag surrounds the outer circumference of the heating tube, fully absorbing the heat generated by the heating tube. A heat transfer bag is installed inside the preheating roller and connected to the heating water bag via a water pipe, transferring heat to the preheating roller, thereby preheating the belt. This design not only improves heat transfer efficiency but also avoids the risk of belt damage caused by direct heating.

[0021] Optionally, a connecting plate is provided on each side facing the heating water bag, the connecting plate is slidably connected to the heating tube, and the connecting plate is fixed to the partition and corresponds one to one;

[0022] A connecting pipe is provided to connect the heating water bags.

[0023] By adopting the above technical solution, the connecting plate is slidably connected to the heating tube and fixed to the partition, so that the partition can drive the connecting plate to squeeze the heating water bag when it moves, so that the water in the heating water bag and the heat transfer water bag flows, thereby improving the uniformity of heat distribution.

[0024] Optionally, a mounting seat is provided on the top of the bearing column, the mounting seat is formed with a mounting groove, and a water storage bag is provided in the mounting groove;

[0025] The water storage bag is provided with a one-way water inlet valve and a one-way water outlet valve, the water delivery pipe is connected to the one-way water outlet valve on the side away from the heat transfer water bag, and a transmission pipe is provided between the one-way water inlet valve and the heating water bag;

[0026] The mounting seat is slidably connected to an extrusion plate for extruding the water storage bag. The machine body is provided with a transmission assembly. When the rolling roller rotates, the transmission assembly drives the extrusion plate to reciprocate and circulate to extrude the water storage bag.

[0027] Using this technical solution, the water storage bladder stores water and connects to the heating and heat transfer bladders via a one-way water inlet and outlet valves, creating a water circulation system. The transmission assembly utilizes the rotational power of the rollers to drive the extrusion plates to reciprocate and squeeze the water storage bladder, creating a water circulation system between the heating and heat transfer bladders, further improving heat uniformity within the water flow.

[0028] Optionally, the transmission assembly includes a transmission cam, a transmission belt, a transmission spring, and a transmission shaft, the transmission shaft is rotatably connected to the mounting seat, and the transmission cam is arranged on the outer peripheral side of the transmission shaft;

[0029] The transmission spring is installed on the mounting seat, and the transmission spring drives the extrusion plate to abut against the transmission cam. The transmission belt is sleeved on the outer peripheral side of the rolling roller and the transmission shaft.

[0030] By adopting the above technical solution, the reciprocating motion of the extrusion plate is achieved through the coordinated use of a transmission cam, a transmission belt, a transmission spring, and a transmission shaft. When the rolling roller rotates, the transmission belt drives the transmission shaft, which in turn drives the rotation of the transmission cam. The transmission spring maintains the extrusion plate in contact with the transmission cam, allowing the extrusion plate to reciprocate as the transmission cam rotates. This design cleverly utilizes the rotational power of the rolling roller to achieve automated operation of the water circulation system.

[0031] Optionally, a heat transfer tube corresponding one-to-one to the heating water bag is provided on the outer periphery of the heating tube, and the heat transfer tube includes an outer tube and an inner tube, the inner tube is slidably connected to the outer tube, the side of the inner tube away from the outer tube is connected to the connecting plate, and the side of the outer tube away from the connecting plate is connected to the supporting column.

[0032] By adopting this technical solution, the heat transfer tube comprises an outer tube and an inner tube. The inner tube is slidably connected to the outer tube and connected to the heating water bag via a connecting plate. This design allows the heat transfer tube to flexibly adjust its position as the partition moves, reducing the possibility of direct contact between the heating tube and the heating water bag, which could damage the water bag.

[0033] Optionally, the control member includes a bidirectional screw rod, the bidirectional screw rod is rotatably connected to the bearing column, and the bidirectional screw rod includes a forward rotation portion and a reverse rotation portion;

[0034] A connecting block is provided on one side of the partition close to the bidirectional screw rod. The connecting block is slidably connected to the bearing column and is threadedly connected to the forward rotation part and the reverse rotation part relative to the connecting block.

[0035] Using this technical solution, the bidirectional screw comprises a forward-rotating portion and a reverse-rotating portion, each threadedly connected to the connecting blocks on the two partitions. By rotating the bidirectional screw, the two partitions can be moved closer or further apart, adjusting the size of the heating space. This design is simple, practical, and easy to operate, allowing it to quickly adapt to the production needs of different belt specifications.

[0036] In a second aspect, the present application provides a method for producing a center-folded hem tape, which adopts the following technical solution:

[0037] A method for producing a center-folded tape comprises the following steps:

[0038] S1: Fabric inspection, fabric inspection is carried out through the fabric inspection machine;

[0039] S2: Laminating, laminating the PU adhesive to one side of the fabric through the laminating machine;

[0040] S3: Cutting the fabric into two types of fabrics with a width equal to the width of the finished tape (1W) and twice the width of the finished tape (2W) using a fabric cutting machine;

[0041] S4: Tear off the paper film on the side of the fabric facing away from the PU adhesive;

[0042] S4: Folding cloth. A cloth guiding member located above the conveyor belt is provided on the feed side of the machine body for folding cloth. The cloth guiding member bends and fits the two long sides of the cloth with a width of 2W along the center line of the cloth in the longitudinal direction, and then heats and presses the cloth to form a center folded belt with two layers of cloth fitted together to a width that matches the width of the finished belt.

[0043] S5: Pressing lining. A whole cloth piece is provided on the feeding side of the machine body for pressing lining. The whole cloth piece pulls the cloth with a width of 1W and the side with PU glue to the top of the side with the slit of the center folding edge belt and aligns them relatively. Then, after heating and rolling for bonding, a finished center folding edge belt is obtained.

[0044] By adopting the above technical solution, the efficient production of center-folded hem tape is achieved through a series of steps such as cloth inspection, film application, cloth cutting, paper tearing, cloth folding, and lining. This method not only has a clear process and is easy to operate, but also can ensure that the quality of the produced tape is stable and the size is accurate. At the same time, this method also makes full use of the various functional characteristics of the equipment to improve production efficiency and product quality. Compared with the traditional center-folded hem tape production, it is necessary to cut out a cloth section with a width twice the width of the finished tape, and then fold the cloth to achieve the production of the center-folded hem tape. When the production method of the present application is used to produce the center-folded hem tape, the cloth is directly cut into cloth with specifications of the finished tape width and twice the finished tape width during production, so that the finished center-folded hem tape produced can be of unlimited length, which greatly facilitates the transportation of the finished center-folded hem tape in the later stage; at the same time, the finished center-folded hem tape can be cut according to the actual required length during subsequent production, which greatly improves the convenience of production.

[0045] Optionally, in step S4, a flexible support material is placed in the middle of the cloth with a width of 2W.

[0046] By adopting the above-mentioned technical solution, during the production process of the folded edge tape, compared with the traditional process of flipping the lock edge side into the middle of the fabric, in this application, a sponge is placed in the middle of the fabric with a width of 2W, so that the finished center folded edge tape has a certain toughness, which is convenient for the use of subsequent production processes and makes the center folded edge tape have better softness, thereby improving the wearing comfort of underwear.

[0047] Optionally, the cloth guiding member includes a support plate, a cloth guiding strip and a partition plate;

[0048] The cloth guide strip is arranged on the support plate, and a first cloth guide hole for inputting cloth with a width of 2W is formed on the cloth guide strip;

[0049] The partition plate is arranged on the cloth-leading strip and is located in the first cloth-leading hole, and a second cloth-leading hole for inputting the flexible supporting material is formed between the partition plate and the first cloth-leading hole;

[0050] The whole fabric piece includes a carrying plate, a first whole fabric strip and a second whole fabric strip;

[0051] The first whole fabric strip is arranged on the supporting plate, and the second whole fabric strip is arranged on a side of the first whole fabric strip away from the supporting plate. The first whole fabric strip is formed with a first whole fabric hole, and the second whole fabric strip is formed with a second whole fabric hole.

[0052] By adopting the above technical solution, the cloth guide piece guides and folds the cloth segment that is twice the width of the finished belt, making it easy to fold the cloth segment; the whole cloth piece arranges the two cloth segments, making it easy to press and line to form a center folded edge belt product.

[0053] In summary, this application has at least one of the following beneficial effects:

[0054] 1. The design of the sliding partitions and control components on the support column allows the size of the heating space to be adjusted to meet the production requirements of different strip specifications. In addition, the installation of the preheating section further increases the temperature of the strip before entering the heating space, reducing the overall heating time and improving production efficiency. The heat transfer component effectively transfers the heat generated by the heating tube to the preheating section, achieving efficient heat utilization.

[0055] 2. The transmission component uses the rotational power of the rolling roller to drive the extrusion plate to reciprocate and squeeze the water storage bag, so that water circulation is formed between the heating water bag and the heat transfer water bag, further improving the uniformity of heat in the water flow.

[0068] The following is combined with Figure 1-11 This application is described in further detail.

[0069] The embodiment of the present application discloses a center-folded edge belt production device.

[0070] The inventors of this application have discovered that in garment manufacturing, the production of strips of clothing, such as shoulder straps, waistbands, and cuffs, typically utilizes traditional cutting and sewing processes. These processes are prone to edge peeling during use, affecting product quality and aesthetics. To address this, this application primarily utilizes the following technical solutions to achieve improved heat utilization, which are described in further detail below.

[0071] See also Figure 1 and Figure 2The production equipment includes a machine body 1, a conveyor belt 11, and a rolling roller 12. The machine body 1 has multiple rotating rollers that rotate symmetrically. The conveyor belt 11 is connected to the machine body and is mounted on the outer periphery of the rotating rollers. The conveyor belt 11 is a rubber belt structure. A drive motor is fixedly mounted on the machine body 1. The output shaft of the drive motor is fixedly connected to one of the rotating rollers. When in use, the drive motor is activated, driving the rotating roller to rotate, causing the conveyor belt 11 to enter a reciprocating rotation state.

[0072] See also Figure 2 and Figure 3 The machine body 1 is rotatably connected to a laminating roller 12, located directly above the central rotating roller. A hydraulic device is installed on the machine body 1 to apply pressure to the laminating roller 12. A pressing space 13 is formed between the laminating roller 12 and the conveyor belt 11. The fabric to be lined is placed on the conveyor belt 11, which then drives the fabric through the pressing space 13. At this point, the laminating roller 12 applies pressure to the fabric, achieving the lining. A traction roller is rotatably connected to the discharge side of the machine body 1, located directly above the conveyor belt 11, for pulling the fabric.

[0073] The production equipment also includes a heating unit 2, which is mounted within the machine body 1 and adjacent to the laminating roller 12. A heating space 21 is formed between the heating unit 2 and the conveyor belt 11. As the conveyor belt 11 transports the fabric, the fabric first passes through the heating space 21. After being heated by the heating unit 2, the fabric then enters the pressing space 13 for laminating.

[0074] The heating part 2 includes a supporting column 3 and a heating tube 4. The supporting column 3 is fixedly connected to the machine body 1. The supporting column 3 is a rectangular structure. The length direction of the supporting column 3 is perpendicular to the transmission direction of the cloth. The supporting column 3 is located directly above the conveyor belt 11, and the supporting column 3 is located on the side of the rolling roller 12 close to the feed.

[0075] The support column 3 is formed with a support slot 31 extending along the length of the support column 3. A heating tube 4 is mounted and fixed to the support column 3 and passes through the support slot 31. The heating tube 4 is an electric heating tube 4. A partition 32 is slidably connected to the bottom of the support column 3. Two partitions 32 are symmetrically arranged, located at the notch of the support slot 31 and close to the width sidewall of the support column 3. In this embodiment, the partitions 32 are several millimeters thick and made of a heat-resistant alloy.

[0076] See also Figure 4 and Figure 5The supporting column 3 is provided with a control component, which controls the two relative partitions 32 to move closer to or farther away from each other. The control component is a bidirectional screw rod 33, which is rotatably connected to the supporting column 3. One end of the bidirectional screw rod 33 is inserted and protrudes out of the body 1, and the bidirectional screw rod 33 is rotatably connected to the body 1. The length direction of the bidirectional screw rod 33 is perpendicular to the length direction of the supporting column 3. The bidirectional screw rod 33 includes a forward rotation part 331 and a reverse rotation part 332. A connecting block 321 is fixedly connected to one side of the bidirectional screw rod 33 relative to the two partitions 32. The two connecting blocks 321 are respectively slidably connected to the supporting column 3, and are respectively threadedly connected to the forward rotation part 331 and the reverse rotation part 332 relative to the connecting block 321. The bidirectional screw rod 33 rotates, and drives the two partitions 32 to move closer to or farther away from each other through the two connecting blocks 321.

[0077] See also Figure 3 and Figure 4 When the width of the fabric is less than the length of the slot opening of the load-bearing slot 31, the bidirectional screw 33 controls the opposing partitions 32 to move closer together, gradually closing the slot opening of the load-bearing slot 31 from both sides toward the center, so that the slot opening length of the load-bearing slot 31 adapts to the fabric width. At this time, the partitions 32 block the heating tube 4; the heating tube 4 generates heat directly through the portion of the slot opening of the load-bearing slot 31 facing the fabric, while the heat generated by the heating tube 4 in the portion facing the partition 32 is dissipated between the two opposing partitions 32, directly affecting the fabric. This reduces the amount of heat generated by the heating tube 4 dissipated directly through the slot opening of the load-bearing slot 31 toward the conveyor belt 11, significantly reducing heat loss. Accordingly, when the width of the next batch of fabric is greater than the length of the slot opening of the load-bearing slot 31, the bidirectional screw 33 controls the opposing partitions 32 to move away from each other, so that the slot opening length of the load-bearing slot 31 adapts to the fabric width.

[0078] See also Figure 1 and Figure 3 The machine body 1 is fixed with an observation window 14, which is made of heat-insulating glass and faces the supporting column 3. When in use, the supporting column 3 can be observed through the observation window 14 to observe the adjustment state of the partition 32.

[0079] The production equipment also includes a preheating unit 5, which is mounted on the sidewall of the support column 3 and includes a support column 6 and a preheating roller 7. The support column 6 is mounted on the side of the support column 3 away from the laminating roller 12. The support column 6 is a rectangular parallelepiped structure, with its length parallel to that of the support column 3. The support column 6 defines a support groove, and the preheating roller 7 is rotatably connected to the support column 6 and located within the support groove.

[0080] A preheating space 51 is formed between the preheating roller 7 and the conveyor belt 11. When the conveyor belt 11 conveys the cloth, the cloth first passes through the preheating space 51 and then passes through the heating space 21. When the cloth passes through the preheating space 51, the preheating roller 7 rolls and preheats the cloth.

[0081] See also Figure 6 and Figure 7 The production equipment also includes a heat transfer component 8, which includes a heating water bag 81, a water pipe 82, and a heat transfer water bag 83. The heating water bag 81 is arranged around the outer periphery of the heating pipe 4. There are two heating water bags 81 and they correspond one to one with the partitions 32. The material of the heating water bags 81 is silicone rubber or fluororubber.

[0082] See also Figure 5 and Figure 7 The heat transfer bladder 83 is installed within the preheating roller 7, with a gap between its outer sidewall and the preheating roller 7. The heat transfer bladder 83 is also made of silicone rubber or fluororubber. The water pipe 82 is made of silicone rubber or fluororubber and passes through the support column 3, the support column 6, and the preheating roller 7. There are two water pipes 82, each corresponding to the heating bladder 81. One end of each water pipe 82 is connected and fixed to the heating bladder 81, and the other end is connected and fixed to the heat transfer bladder 83. The ends of the two water pipes 82, facing away from the heating bladder 81, are positioned opposite each other on the heat transfer bladder 83. The heating bladder 81 and the heat transfer bladder 83 store water, respectively. The portion of the heating pipe 4 facing the partition 32 heats the water in the heating bladder 81. The heat is then transferred through the water pipe 82 to the heat transfer bladder 83. The heat in the heat transfer bladder 83 is then dissipated outward, heating the preheating roller 7.

[0083] Connecting plates 811 are fixedly connected to the opposing sides of the two heating water bags 81. These connecting plates 811 are slidably connected to the heating tubes 4. The connecting plates 811 are fixed to the partitions 32 and correspond one-to-one. Furthermore, a connecting tube 812 is fixedly connected between the opposing heating water bags 81. Initially, the connecting tube 812 is relaxed, connecting the two heating water bags 81. When the partitions 32 move away from each other, the connecting plates 811 squeeze the heating water bags 81, causing the water in the heating water bags 81 to flow into the heat transfer bag 83, facilitating heat transfer.

[0084] To reduce the possibility of direct contact between the heating tube 4 and the heating water bladder 81, which could damage it, a heat transfer tube 41 is sheathed around the outer circumference of the heating tube 4. Two heat transfer tubes 41 correspond to each heating water bladder 81. The heat transfer tubes 41 comprise an outer tube 411 and an inner tube 412. The inner tube 412 is slidably connected to the outer tube 411 and coaxially arranged. The inner tube 412 is fixedly connected to the connecting plate 811 on the side facing away from the outer tube 411, while the outer tube 411 is fixedly connected to the supporting column 3 on the side facing away from the connecting plate 811. When the partition 32 slides, the inner tube 412 slides against the outer tube 411, adjusting the material of the heat transfer tube 41.

[0085] See also Figure 7 and Figure 8 To ensure the flow of water in the heating water bladder 81 and the heat transfer water bladder 83, a mounting base 34 is fixed to the top of the support column 3. The mounting base 34 has a mounting groove 341 formed therein, and the notch of the mounting groove 341 is formed on one side wall of the mounting base 34. A water storage bladder 342 is fixed to the mounting base 34. The water storage bladder 342 is located in the mounting groove 341, and the outer wall of the water storage bladder 342 is fixedly connected to the wall of the mounting groove 341 on the side away from the notch.

[0086] A one-way water inlet valve 3421 and a one-way water outlet valve 3422 are fixedly connected to the water storage bladder 342. The one-way water inlet valve 3421 and the one-way water outlet valve 3422 are arranged opposite each other. One of the water delivery pipes 82 is fixedly connected to the one-way water outlet valve 3422 on the side away from the heat transfer bladder 83. A delivery pipe 3423 is fixedly connected between the one-way water inlet valve 3421 and the heat transfer bladder 81.

[0087] The mounting seat 34 is slidably connected to a squeezing plate 3424 , which is fixed to the outer wall of the water storage bag 342 , and is located on a side of the water storage bag 342 facing the notch of the mounting groove 341 .

[0088] See also Figure 3 The body 1 is provided with a transmission assembly 9, which includes a transmission cam 91, a transmission belt 92, a transmission spring 93, and a transmission shaft 94. The transmission shaft 94 is rotatably connected to the mounting seat 34 and is located near the notch of the mounting slot 341. The transmission cam 91 is fixedly connected to the outer periphery of the transmission shaft 94. The transmission cam 91 is slidably connected to the side of the extrusion plate 3424 facing away from the water storage bladder 342. A limiting block is fixedly connected to the side wall of the extrusion plate 3424. The wall of the mounting slot 341 is formed with a limiting groove for the limiting block to slide. The transmission spring 93 is installed in the limiting groove. When the transmission spring 93 is released, it pushes the extrusion plate 3424 toward the notch of the mounting slot 341, so that the extrusion plate 3424 remains in contact with the transmission cam 91.

[0089] The transmission belt 92 is mounted around the outer periphery of the laminating roller 12 and the transmission shaft 94. When the laminating roller 12 rotates, the transmission belt 92 drives the transmission shaft 94 to rotate, causing the transmission cam 91 to push the extrusion plate 3424 against the water storage bladder 342. When the protruding portion of the transmission cam 91 moves away from the extrusion plate 3424, the transmission spring 93 is elastically released, pushing the extrusion plate 3424 toward the notch of the mounting slot 341, keeping the extrusion plate 3424 in contact with the transmission cam 91. When the extrusion plate 3424 squeezes the water storage bladder 342, the water in the water storage bladder 342 flows out through the one-way water outlet valve 3422 and into the heat transfer bladder 83. Then, when the extrusion plate 3424 moves toward the notch of the mounting slot 341, the water in the heating water bladder 81 flows through the one-way water inlet valve 3421 and into the water storage bladder 342, allowing the water in both the heating water bladder 81 and the heat transfer bladder 83 to flow.

[0090] The implementation principle of a center hem tape production device according to an embodiment of the present application is as follows:

[0091] Before production, the position of the partitions 32 is adjusted according to the belt width, so that the length of the slots 31 adapts to the width of the fabric. During production, the fabric to be lined is placed on the conveyor belt 11, which then drives the fabric through the preheating space 51, the heating space 21, and the laminating space 13. While passing through the preheating space 51, the preheating roller 7 preheats and pre-presses the fabric. The fabric then passes through the heating space 21, where it is heated by the heating tube 4. Finally, as the fabric passes through the laminating space 13, it is lined by the laminating roller 12.

[0092] When the heating tube 4 heats the fabric, the portion of the heating tube 4 facing the partition 32 heats the heating water bladder 81. The heat then transfers and diffuses into the heat transfer bladder 83, heating the water flow within the heat transfer bladder 83. Furthermore, as the rolling roller 12 rotates, the transmission cam 91 rotates, causing the squeezing plate 3424 to cyclically squeeze the water storage bladder 342, creating a fluid flow between the heat transfer bladder 83 and the heating water bladder 81, improving the uniformity of heat within the water flow.
