Description

Technical Field

[0001] This utility model relates to a ribbon feeding and hot-pressing device, belonging to the field of bow tie machinery technology. Background Technology

[0002] As a classic clothing accessory, the bow tie's manufacturing process mainly includes the following steps: First, the material is pulled, cut, folded, and ironed together to form the upper part of the bow tie. Then, it is assembled with the fishtail ribbon into a complete product through a waist-wrapping process.

[0003] With the increasing market demand for mass production and personalized manufacturing, achieving full automation of the bow tie manufacturing process has become a clear industry trend. However, existing equipment still has shortcomings in achieving continuous feeding and folding / ironing of the material strip, requiring a high degree of manual intervention, which restricts the improvement of overall production efficiency and automation level.

[0004] Therefore, there is an urgent need to provide a tape feeding and hot-pressing device to improve the production efficiency of bow ties. Utility Model Content

[0005] One objective of this application is to provide a tape feeding and hot-spinning device, which aims to at least solve one of the technical problems existing in the prior art. According to the tape feeding and hot-spinning device of this application, the production efficiency of bow ties can be improved.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a tape feeding and hot-welding device, comprising:

[0007] The frame is provided with a forming station, and the forming station has a worktable;

[0008] A belt feeding mechanism, located on the frame and on one side of the worktable, is used to provide belt material;

[0009] A belt pulling mechanism, located on the frame and on the other side of the workbench, is used to pull the material belt;

[0010] The belt pressing mechanism includes a first belt pressing component, which is movably located above the worktable and is used to press a portion of the belt onto the worktable.

[0011] A strip cutting mechanism is located on the side of the strip feeding mechanism near the worktable, and is used to cut the strip to obtain the strip to be formed;

[0012] The folding mechanism includes two sets of folding strap assemblies, which are arranged opposite to each other on both sides of the worktable for folding the strip components.

[0013] The heat-sealing mechanism is equipped with heat-sealing needles that can be moved to the worktable. The heat-sealing needles are used to heat-seale folded strips.

[0014] The strip has a first section, a middle section and a last section connected in sequence. The first pressing member is configured to press the middle section against the worktable. The first section and the last section are constrained by the first pressing member and can be folded and at least partially overlapped by two sets of folding assemblies, so that the hot-pressing needle can hot-press the strip.

[0015] In this application, the coordinated operation of the strap-pulling mechanism, strap-pressing mechanism, strap-cutting mechanism, folding mechanism, and heat-sealing mechanism enables automated continuous production of the upper part of the bow tie. The specific process is as follows: the strap-pulling mechanism pulls the material tape from the supply mechanism to the worktable, where it is pressed by the strap-pressing mechanism and then cut by the strap-cutting mechanism to form a strip. The middle section of this strip remains stable under the continuous pressure of the strap-pressing mechanism. The two sets of folding components of the folding mechanism then move to precisely fold the first and last sections of the strip towards the middle. Subsequently, the heat-sealing needle of the heat-sealing mechanism presses down and heat-fuses the joint, thus forming the basic upper part of the bow tie. This design seamlessly connects the pulling, pressing, cutting, folding, and heat-sealing processes, reducing manual intervention. This not only significantly improves production cycle time and operational consistency but also further ensures the standardization of the size and shape of the semi-finished product, thereby effectively improving the production efficiency and product yield of the bow tie.

[0040] The fifth driving component is fixedly mounted on the third upright, and the heating needle is fixedly connected to the output end of the fifth driving component;

The correction mechanism is used to actively correct the lateral deviation of the belt during its movement, while the limiting mechanism is used to constrain the vertical floating of the belt. The cooperation between the two forms an integrated constraint on the "lateral" and "vertical" degrees of freedom of the belt, suppressing the belt deviation and shaking phenomenon, and providing a crucial foundation for subsequent precise cutting, folding and heat treatment processes, thereby effectively improving the processing accuracy and reliability of the entire device.

[0074] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0075] In the process of shaping the upper part of the bow tie from the fabric strip, multiple steps are required, including pulling, cutting, folding, and ironing. Currently, key steps in this process, such as folding positioning, maintaining the posture, and synchronous ironing, still rely on manual operation. This work mode not only limits production efficiency but also directly affects the quality stability of the final product due to the difficulty in ensuring operational consistency. Defects such as asymmetrical folding, insufficient ironing strength, or uneven positioning often occur, thus becoming a bottleneck restricting the automation upgrade of bow tie production.

[0076] Please see Figure 1 and Figures 3-4In this embodiment of the application, a tape feeding and heat-sealing device includes a frame 100, a tape supply mechanism 200, a tape pulling mechanism 300, a tape pressing mechanism 400, a tape cutting mechanism 500, a folding mechanism 600, and a heat-sealing mechanism 700. The frame 100 has a forming station 110 with a worktable 111. The tape supply mechanism 200 is located on one side of the worktable 111 and is used to supply tape. The tape pulling mechanism 300 is located on the other side of the worktable 111 and is used to pull the tape. The tape pressing mechanism 400 has a first tape pressing member 410, which is movably located above the worktable 111 and is used to press a portion of the tape onto the worktable 111. The tape cutting mechanism 500 is located on the side of the tape supply mechanism 200 near the worktable 111 and is used to cut the tape to obtain the strip D to be formed. The folding mechanism 600 includes two sets of folding assemblies, which are arranged opposite each other on both sides of the worktable 111 for folding the strip D. The heat-sealing mechanism 700 is provided with heat-sealing needles 710 movable to the worktable 111 for heat-sealing the folded strip D. The strip D has a first segment D1, a middle segment D2, and a last segment D3 connected in sequence. A first pressing member 410 is configured to press the middle segment D2 against the worktable 111. The first segment D1 and the last segment D3 are constrained by the first pressing member 410 and can be folded by the two sets of folding assemblies respectively and at least partially overlapped, so that the heat-sealing needles 710 can heat-seale the strip D.

[0077] The frame 100 serves as an integrated platform for mounting various functional mechanisms. A forming station 110 is provided on the frame 100. This forming station 110 is a dedicated area for processing the strip into a semi-finished product (i.e., the upper part of the bow tie). It is equipped with a worktable 111, where all the specific forming operations of the strip are sequentially completed. A feeding mechanism 200 stores and releases the rolled strip. A pulling mechanism 300 pulls the strip released by the feeding mechanism 200 to the worktable 111 of the forming station 110. A pressing mechanism 400 presses and fixes the strip to the worktable 111 before cutting. A cutting mechanism 500 cuts the pressed strip to form independent strip pieces D. A folding mechanism 600 folds the first segment D1 and the last segment D3 of the strip piece D towards its pressed middle segment D2. The heat-pressing mechanism 700 is used to heat-press and fix the folded joints, so that the strip D is finally formed into the required semi-finished product.

[0078] When the feeding and hot-spinning device is working, the pulling mechanism 300 first clamps the end of the material strip led out from the feeding mechanism 200 and pulls it through the worktable 111 of the forming station 110 on the frame 100. Then, the first pressing member 410 of the pressing mechanism 400 moves down and presses part of the material strip to the surface of the worktable 111. Immediately afterwards, the cutting mechanism 500 cuts the material strip, so that the cut part forms the strip D to be formed. The part of the strip D that is continuously pressed by the first pressing member 410 is defined as the middle section D2. The two sides of the middle section D2 are the first section D1 and the last section D3, respectively. After that, the two sets of folding components of the folding mechanism 600 move in sequence, folding the first section D1 and the last section D3 towards the middle section D2. After the folding is completed, the hot-spinning needle 710 of the hot-spinning mechanism 700 moves down and heats the overlapping part of the strip D, so that the material strip is fused and fixed, and finally a structurally stable semi-finished product is formed.

[0079] This application achieves fully automated continuous forming of the upper part of the bow tie through the coordinated control of the feeding mechanism, the pulling mechanism 300, the pressing mechanism 400, the cutting mechanism 500, the folding mechanism 600, and the ironing mechanism 700. This integrated design creates a continuous workflow for the pulling, pressing, cutting, folding, and heat-curing processes, significantly reducing manual intervention and coordination between stages. This not only significantly improves production cycle stability and operational consistency but also fundamentally ensures the standardization of semi-finished products in terms of size and shape, thereby improving the overall production efficiency and product qualification rate of bow ties.

[0080] In some embodiments, please refer to Figure 1 and Figure 5 The tape feeding mechanism 200 includes a first upright 210, a tape feeding frame 220, a tape feeding motor 230, and a lifting roller 240. The first upright 210 is fixedly mounted on the frame 100. The tape feeding frame 220 is rotatably mounted above the first upright 210 and is used to mount the tape roll. The tape feeding motor 230 is fixedly mounted on the first upright 210 and its output end is connected to the tape feeding frame 220. It is used to drive the tape feeding frame 220 to rotate and feed tape. The lifting roller 240 is raised and lowered on the first upright 210 and located below the tape feeding frame 220. It is used to tighten the tape fed from the tape feeding frame 220. The first upright 210 is fixedly mounted with two sensors 250. The two sensors 250 are spaced apart in the vertical direction and are each configured to detect the lifting roller 240, so that the tape feeding frame 220 starts or stops feeding tape.

[0081] Two sensors 250 are defined as a first sensor 251 and a second sensor 252, respectively, and are arranged vertically at intervals, with the first sensor 251 located above the second sensor 252. When the lifting roller 240 moves upward and is detected by the first sensor 251, the first sensor 251 outputs a control signal to drive the tape feeding motor 230 to start, so that the tape feeding frame 220 performs the tape feeding action. When the lifting roller 240 moves downward and is detected by the second sensor 252, the second sensor 252 outputs a control signal to stop the tape feeding motor 230, so that the tape feeding frame 220 stops feeding tape.

[0082] The belt feeding mechanism 200 is normally in a stopped belt feeding state, and the belt feeding motor 230 is not working. When the belt pulling mechanism 300 pulls the belt towards the worktable 111, the tension of the belt causes the lifting roller 240 to rise along the first upright 210. When the lifting roller 240 passes and triggers the first sensor 251, the first sensor 251 sends a signal to start the belt feeding motor 230, driving the belt feeding frame 220 to rotate, thus realizing the active feeding of the belt roll. During the feeding process, the lifting roller 240 descends along the first upright 210 under the action of gravity. When it passes and triggers the second sensor 252, the second sensor 252 sends a signal to stop the belt feeding motor 230, and the belt roll immediately stops feeding.

[0083] By setting a first sensor 251 and a second sensor 252 at intervals on the first upright 210, and forming a closed-loop control with the tape feeding motor 230, automated management of tape supply is achieved. When the lifting roller 240 rises and triggers the first sensor 251, the system automatically starts the tape feeding motor 230 for active feeding. When the lifting roller 240 descends and triggers the second sensor 252, the motor automatically stops, ending tape feeding. This design enables the tape feeding mechanism 200 to automatically and accurately execute tape feeding and stopping actions according to the material pulling requirements, maintaining stable tape tension and supply rhythm without manual intervention, significantly improving the automation level, response speed, and reliability of the entire feeding process.

[0084] In this embodiment, two parallel guide rods 211 are fixed at intervals on the first upright 210, and a slide rail extending in the vertical direction is formed between the two guide rods 211. A guide wheel 241 is installed on one side of the lifting roller 240, and the guide wheel 241 is embedded between the two guide rods 211, so that the lifting roller 240 can move up and down smoothly in the vertical direction.

[0085] In this embodiment, a guide roller 260 is also fixed on the first upright 210. After the material belt passes around the lifting roller 240, it is reversed by the guide roller 260. The guide roller 260 helps to guide the direction of the material belt, reduce friction and jamming during the conveying process, and ensure the smooth and stable transmission of the material belt tension.

[0086] In some embodiments, please refer toFigures 1-3 The combination of the belt pulling mechanism 300 includes a first driving member 310 and a clamping member 320. The first driving member 310 is fixedly disposed on one side of the worktable 111, and the clamping member 320 is fixedly connected to the output end of the first driving member 310. The first driving member 310 is configured to drive the clamping member 320 to move left and right, so that the clamping member 320 can clamp the belt and pull it through the worktable 111.

[0087] When the material strip needs to be pulled to the worktable 111, the first drive member 310 first drives the clamping member 320 to move to the right until it reaches the end position of the material strip. Then the clamping member 320 performs a clamping action to firmly clamp the end of the material strip. Next, the first drive member 310 drives the clamping member 320 to move to the left (i.e., the return direction), thereby pulling the material strip continuously over the worktable 111, preparing for subsequent forming processes such as pressing and cutting.

[0088] The belt conveyor mechanism 300, through the coordinated action of the first driving component 310 and the clamping component 320, achieves fully automated and precise conveying of the belt from the feeding end to the processing station. This mechanism automatically completes a series of actions, including reliable clamping of the belt end and fixed-distance traction, replacing traditional manual traction and positioning operations. This not only significantly reduces labor intensity and operation time but also ensures the consistency of the conveying length and positioning position of each belt segment through the repeatability of mechanical drive. This provides a stable and accurate material basis for subsequent cutting, folding, and other processes, effectively improving the automation level and process reliability of the overall production process.

[0089] In this embodiment, the molding station 110 is provided with a first guide rail 330 extending horizontally, and a first slide block 340 is slidably disposed on the first guide rail 330. The output end of the first drive member 310 and the clamping member 320 are respectively fixedly connected to the first slide block 340. Through the guiding constraint of the first guide rail 330 and the first slide block 340, the first drive member 310 can drive the clamping member 320 to move stably and accurately back and forth along a preset straight path.

[0090] In this embodiment, the molding station 110 is also provided with a first stop 350, which is used to contact and stop the first slide 340 when it slides to the preset end point of the stroke, thereby preventing the first slide 340 from sliding beyond its stroke.

[0091] In this embodiment, the first driving member 310 can be a cylinder or other driving element with equivalent linear output function, and the clamping member 320 can be a pneumatic gripper or other clamping element with equivalent clamping function. The traction length of the material strip is controlled and set by the effective stroke of the first driving member 310.

[0092] In some embodiments, please refer to Figures 2-3The pressing mechanism 400 also includes a second upright 420 and a second drive member 430. The second upright 420 is fixedly mounted on the frame 100, and the second drive member 430 is fixedly mounted on the second upright 420. The first pressing member 410 is fixedly connected to the output end of the second drive member 430. The first pressing member 410 has a plurality of first pressing sections 411 spaced apart in the left-right direction. The second drive member 430 is configured to drive the first pressing member 410 to move up and down, so that the first pressing sections 411 press part of the material strip onto the worktable 111 for cutting.

[0093] After the belt pulling mechanism 300 pulls the belt and passes it over the worktable 111, the second driving member 430, which is supported by the second upright 420 fixed on the frame 100, starts to move, driving the first pressing member 410 to move downward in the vertical direction, so that the first pressing part 411 at its bottom contacts and stably presses against the belt on the surface of the worktable 111, thereby achieving the pressing and fixing of the belt.

[0094] The pressing mechanism 400 drives the first pressing component 410 to perform stable pressing on the positioned material strip, providing a crucial foundation for the subsequent cutting process. Its local fixation of the material strip effectively reduces the possibility of it shifting or shrinking during the subsequent cutting process, ensuring the dimensional accuracy and positional consistency of the cut. It also provides a stable intermediate product for subsequent folding, heat treatment, and other processes, thereby enhancing the overall continuity of the forming process and the quality stability of the final product.

[0095] In this embodiment, the first pressing member 410 can be constructed as a plate-like structure, and the first pressing part 411 is a column fixed to the first pressing member 410.

[0096] In this embodiment, the second driving element 430 can be a cylinder or other driving element with equivalent linear output function.

[0097] In some embodiments, please refer to Figures 2-3 The tape cutting mechanism 500 includes a third drive member 510 and a heating wire 520. The third drive member 510 is fixedly disposed on the side of the tape feeding mechanism 200 near the worktable 111. The heating wire 520 is fixedly connected to the output end of the third drive member 510. The third drive member 510 is configured to drive the heating wire 520 to move up and down, so that the heating wire 520 can cut the tape.

[0098] After the strip is pressed and fixed on the worktable 111 by the pressing mechanism 400, the third driving component 510 is activated, driving the heating wire 520 to move downward in the vertical direction. When the heating wire 520 contacts the pressed strip, it heats up rapidly due to the power supply, thereby cutting the strip and forming an independent strip D. This strip D is the workpiece to be formed in the subsequent folding and heat-pressing processes.

[0099] The cutting mechanism 500 uses a heating wire 520 for hot cutting, which enables rapid and precise separation of the material strip. The fibers at the cut edge of the material strip melt and bond together to form a natural edge seal, effectively improving the burrs and loose fibers that may be produced by traditional mechanical cutting, and enhancing the edge quality and overall aesthetics of the strip component D.

[0100] In this embodiment, the heating wire 520 is connected to a transformer (not shown in the figure). By controlling the current parameters output by the transformer, the working temperature of the heating wire 520 can be precisely adjusted so that it can instantly reach the temperature required for cutting when it contacts the material strip, thereby realizing the rapid cutting of the material strip.

[0101] In this embodiment, the two ends of the heating wire 520 are fixed on a base 530, which is connected to the output end of the third driving member 510, so that the heating wire 520 can move up and down in the vertical direction under the drive of the third driving member 510.

[0102] In this embodiment, the third driving element 510 can be a cylinder or other driving element with equivalent linear output function.

[0103] In some embodiments, please refer to Figures 2-4 The combination of the two folding components includes a fourth driving member 610 and a folding member 620. The fourth driving member 610 is fixedly mounted on one side of the worktable 111, and the folding member 620 is fixedly connected to the output end of the fourth driving member 610. The fourth driving members 610 of both folding components are configured to drive the corresponding folding member 620 to move left and right, so as to fold the first segment D1 and the last segment D3 accordingly.

[0104] After the strip is cut by the cutting mechanism 500, it forms an independent strip D. The part of the strip D that is continuously pressed against the worktable 111 by the pressing mechanism 400 is the middle section D2, while the unconstrained parts on both sides of the middle section D2 are the freely movable first section D1 and last section D3, respectively. At this time, the two sets of folding components of the folding mechanism 600 are activated in sequence. Each set of folding components drives the corresponding folding component 620 to move horizontally towards the middle section D2 through its fourth driving component 610. Under this drive, the two folding components 620 contact and push the first section D1 and last section D3 of the strip D, so that they move precisely towards the middle section D2 along a preset trajectory and complete the folding, thereby folding the originally flat strip D into a preliminary shape with a layered structure to be fixed.

[0105] The folding mechanism 600 achieves precise folding of the first section D1 and the last section D3 of the strip D towards the middle section D2 through two sets of folding belt components. This significantly improves the operation speed and consistency, and improves the problems of asymmetry and angle deviation that are prone to occur in manual operation. At the same time, the mechanism is seamlessly connected with the preceding and following processes, and completes the folding under the pressure state. This effectively reduces the displacement or springback of the strip D, ensures the stability of the semi-finished product shape, and provides a precise overlapping structure for subsequent hot stamping and fixing, thereby improving the molding quality and the smoothness of automated production.

[0106] In this embodiment, the folding strip 620 can be constructed as a plate-like structure.

[0107] In this embodiment, the worktable 111 is provided with a second guide rail 630 extending horizontally, and a second slide block 640 is slidably disposed on the second guide rail 630. The output end of the fourth drive member 610 is fixedly connected to the folding belt member 620 and the second slide block 640 respectively. Through the guiding constraint of the second guide rail 630 and the second slide block 640, the fourth drive member 610 can drive the folding belt member 620 to reciprocate stably and accurately along a preset straight path.

[0108] In this embodiment, the molding station 110 is also provided with a second stop 650, which is used to contact and stop the second slide 640 when it slides to the preset end point of the stroke, thereby preventing the second slide 640 from sliding beyond its stroke.

[0109] In this embodiment, the fourth driving element 610 can be a cylinder or other driving element with equivalent linear output function.

[0110] In some embodiments, please refer to Figures 1-3 and Figures 6-7 The heat-sealing mechanism 700 also includes a third support 720 and a fifth drive member 730. The third support 720 is fixedly mounted on the frame 100, and the fifth drive member 730 is fixedly mounted on the third support 720. The heat-sealing needle 710 is fixedly connected to the output end of the fifth drive member 730. The fifth drive member 730 is configured to drive the heat-sealing needle 710 to move up and down, so that the heat-sealing needle 710 heats the folded strip D.

[0111] After the strip D is folded in half by the folding mechanism 600, the fifth driving component 730, which is supported by the third upright 720 fixed on the frame 100, starts to move, driving the heating pin 710 to move downward in the vertical direction, so that the heating end of the heating pin 710 contacts the folded and overlapping part of the strip D. Through heat conduction, the strip D is melted and bonded, thereby permanently fixing its folded shape and forming a stable prototype of the upper part of the bow tie.

[0112] The heat-pressing needle 710 used in the heat-pressing mechanism 700 reduces the heat-affected zone on the surface of the strip D, maximizing the preservation of the original texture and visual effect of the strip D. It improves the hardening, discoloration or obvious marks on the fabric that may be caused by traditional large-area heat pressing or sewing, thereby enhancing the product's appearance and aesthetics.

[0113] The heating needle 710 achieves its heating function by being powered by an external power source. The power source is existing technology and will not be described in detail in this article.

[0114] In this embodiment, the third support 720 is provided with a third guide rail 760 extending vertically, and the third slide 770 is slidably disposed on the third guide rail 760. The output end of the fifth drive member 730 is fixedly connected to the heating needle 710 and the third slide 770 respectively. Through the guiding constraint of the third guide rail 760 and the third slide 770, the fifth drive member 730 can drive the heating needle 710 to reciprocate stably and accurately along a preset straight path.

[0115] In this embodiment, the fifth driving element 730 can be a cylinder or other driving element with equivalent linear output function.

[0116] In some embodiments, please refer to Figures 1-3 and Figures 6-7 The heat-pressing mechanism 700 also includes a sixth driving member 740 and a second pressing member 750. The sixth driving member 740 is fixedly mounted on the third upright 720, and the second pressing member 750 is fixedly connected to the output end of the sixth driving member 740. The second pressing member 750 has a second pressing part 751, and the second pressing part 751 forms a clearance part 752. The sixth driving member 740 is configured to drive the second pressing member 750 to move up and down, so that the second pressing part 751 presses the folded strip D. The heat-pressing needle 710 passes through the clearance part 752 and heats the strip D under the drive of the fifth driving member 730.

[0117] Before the hot stamping needle 710 moves down to perform hot stamping, the sixth drive member 740, which is supported by the third upright 720 fixed on the frame 100, starts to move first, driving the second pressure band member 750 to move downward in the vertical direction, so that the second pressure band part 751 set at its bottom contacts and stably presses against the folded part of the strip member D. After the pressing is completed, the fifth drive member 730 drives the hot stamping needle 710 to move downward in the vertical direction. The hot stamping needle 710 passes through the avoidance part 752 set in the second pressure band member 750 and acts on the pressed folded area, thereby performing hot melt hot stamping.

[0118] By pre-pressing the second pressing section 751, the air gap of the strip D after folding is effectively reduced and it is made to fit tightly, providing a flat and stable contact interface for subsequent hot stamping, ensuring the uniformity of heat transfer and the uniformity of welding depth. At the same time, the pressing action can suppress the possible shrinkage or displacement of the strip D when heated, reduce the alignment deviation caused by material deformation, and thus ensure the accuracy of the welding point position.

[0119] In this embodiment, the third support frame 720 is further provided with a fourth guide rail 780 extending vertically, and a fourth slide block 790 is slidably disposed on the fourth guide rail 780. The output end of the sixth drive member 740 and the second pressure band member 750 are respectively fixedly connected to the fourth slide block 790. Through the guiding constraint of the fourth guide rail 780 and the fourth slide block 790, the sixth drive member 740 can drive the second pressure band member 750 to reciprocate stably and accurately along a preset straight path.

[0120] In this embodiment, the second pressing member 750 can be constructed as an L-shaped plate structure, which is fixedly connected to the fourth slide 790 by a connecting plate 753. The second pressing part 751 is the bottom of the second pressing member 750, and the clearance part 752 is a slot opened on the second pressing part 751.

[0121] In this embodiment, the sixth driving element 740 can be a cylinder or other driving element with equivalent linear output function.

[0122] In some embodiments, please refer to Figures 1-2 and Figure 8 The combination also includes a limiting mechanism 800, which includes a limiting base 810 and a limiting top seat 820. The limiting base 810 is fixedly disposed on the side of the feeding mechanism 200 near the cutting mechanism 500. The limiting base 810 has a threading groove 811, through which the material belt is pulled. The limiting top seat 820 is disposed above the limiting base 810 and its height relative to the limiting base 810 is adjustable. When the material belt is pulled through the threading groove 811, the limiting top seat 820 is configured to abut against the top surface of the material belt for limiting.

[0123] After the material belt is led out from the feeding mechanism 200, it passes through the threading groove 811 of the limiting base 810 during traction. The limiting top seat 820, which is set above the material belt, has its bottom surface abutting against the top surface of the material belt and together with the bottom of the threading groove 811, it forms a clamping space for the material belt, thereby forming a limiting constraint on the material belt in the vertical direction.

[0124] The installation height of the limiting top seat 820 can be flexibly adjusted according to the actual thickness of the material strip used, ensuring that appropriate limiting is provided for material strips of different specifications. The synergistic cooperation between the limiting base 810 and the limiting top seat 820 in the vertical direction constitutes bidirectional limiting of the material strip, effectively suppressing the vertical shaking and floating phenomenon that easily occurs during the traction process of the material strip, thereby significantly improving the stability and position of the material strip conveying, laying a reliable foundation for subsequent cutting and forming processes.

[0125] In this embodiment, the installation height of the limiting top seat 820 can be adjusted by bolts.

[0126] In some embodiments, please refer to Figures 1-2 and Figure 8 The combination also includes a correction mechanism 900, which includes a mounting base 910 and two correction rings 920. The mounting base 910 is fixedly mounted on the side of the feeding mechanism 200 near the limiting mechanism 800. The mounting base 910 has a shaft 911 extending in the front-rear direction. The two correction rings 920 are spaced apart and sleeved on the shaft 911. When the material belt is pulled between the two correction rings 920, the correction rings 920 are configured to abut against the side of the material belt to perform correction.

[0127] After the belt is led out from the feeding mechanism 200, it passes through the correction mechanism 900 for guidance and correction before entering the limiting mechanism 800. When the belt passes through the gap between the two correction rings 920 along the conveying direction, its two sides in the width direction are laterally abutted by the two correction rings 920 respectively. Through this symmetrical lateral constraint, the lateral deviation of the belt generated during the conveying process can be automatically corrected, so that it returns to the preset center path, thereby realizing the correction function.

[0128] The correction mechanism 900 applies symmetrical lateral constraints to both sides of the material belt through two correction rings 920, which effectively realizes the automatic correction of the material belt's travel path. It can correct the lateral deviation of the material belt during the traction process in real time, ensuring that the material belt is always conveyed along the preset center line, providing a reliable position reference for subsequent precise cutting and folding.

[0129] In some embodiments, a PLC controller (not shown) is also included, which is electrically connected to the tape feeding mechanism 200, the tape pulling mechanism 300, the tape pressing mechanism 400, the tape cutting mechanism 500, the folding mechanism 600, and the tape heating mechanism 700, respectively.

[0130] As the core control unit of the tape feeding and hot-pressing device, the PLC controller establishes electrical connections with each circuit component in the tape feeding mechanism 200, tape pulling mechanism 300, tape pressing mechanism 400, tape cutting mechanism 500, folding mechanism 600 and hot-pressing mechanism 700. It can send control commands to the corresponding actuators to coordinate and drive the components to work together, and finally realize the continuous conveying and forming of the tape.

[0131] As an exemplary first embodiment, when the feeding and hot-spinning device is working, the pulling mechanism 300 first clamps the end of the material strip led out from the feeding mechanism 200 and pulls it through the worktable 111 on the frame 100. Then, the first pressing member 410 of the pressing mechanism 400 moves down to press and fix part of the material strip on the surface of the worktable 111. Immediately afterwards, the cutting mechanism 500 cuts the material strip, so that the cut part forms a strip D to be formed. The part of the strip D that is continuously pressed by the first pressing member 410 is defined as the middle section D2. The two sides of the middle section D2 are the first section D1 and the last section D3, respectively. After that, the two sets of folding components of the folding mechanism 600 move in sequence to fold the first section D1 and the last section D3 toward the middle section D2. After the folding is completed, the hot-spinning needle 710 of the hot-spinning mechanism 700 moves down to heat the overlapping part of the strip D, so that the material strip is welded and fixed, and finally a structurally stable semi-finished product is formed.

[0132] As an exemplary second embodiment, when the feeding and hot-spinning device is working, the pulling mechanism 300 first clamps the end of the material strip led out from the feeding mechanism 200 and pulls it through the worktable 111 on the frame 100. Then, the first pressing member 410 of the pressing mechanism 400 moves down to press and fix part of the material strip on the surface of the worktable 111. Immediately afterwards, the cutting mechanism 500 cuts the material strip, so that the cut part forms a strip D to be formed. The part of the strip D that is continuously pressed by the first pressing member 410 is defined as the middle section D2. The two sides of the middle section D2 are the first section D1 and the last section D3, respectively. After that, the two sets of folding components of the folding mechanism 600 move in sequence to fold the first section D1 and the last section D3 toward the middle section D2. After the folding is completed, the hot-spinning needle 710 of the hot-spinning mechanism 700 moves down to heat the overlapping part of the strip D, so that the material strip is welded and fixed, and finally a structurally stable semi-finished product is formed.

[0133] In this system, the belt feeding mechanism 200 is normally in a stopped belt feeding state, and the belt feeding motor 230 is not operating. When the belt pulling mechanism 300 pulls the belt towards the worktable 111, the tension of the belt causes the lifting roller 240 to rise along the first upright 210. When the lifting roller 240 passes and triggers the first sensor 251, the first sensor 251 sends a signal to start the belt feeding motor 230, driving the belt feeding frame 220 to rotate, thus realizing the active feeding of the belt roll. During the feeding process, the lifting roller 240 descends along the first upright 210 under the action of gravity. When it passes and triggers the second sensor 252, the second sensor 252 sends a signal to stop the belt feeding motor 230, and the belt roll immediately stops feeding.
