Description

Technical Field

[0001] This utility model relates to the field of cotton clothing production technology, specifically a seamless hot press for cotton clothing production. Background Technology

[0002] With the upgrading of consumption and the continuous development of clothing technology, cotton-padded clothing, as the mainstream clothing for keeping warm in winter, has received increasing attention from the market for its quality and craftsmanship details. Seamless design, as one of the key technologies to improve the grade of cotton-padded clothing, can effectively reduce the gaps at the fabric splicing points, which not only enhances the warmth performance of cotton-padded clothing, but also improves the wearing comfort and appearance. Therefore, it is increasingly widely used in the production of mid-to-high-end cotton-padded clothing. Hot pressing technology, as the core means to achieve seamless cotton-padded clothing, melts and bonds the hot melt adhesive between the fabrics through the synergistic effect of heat and pressure. Its process stability directly affects the bonding strength and overall quality of cotton-padded clothing, and is an important link in the cotton-padded clothing production process to ensure product quality.

[0003] In the prior art, seamless hot press machines for cotton garments typically consist of a frame, a hot press mechanism, and a worktable. During operation, the operator lays the cotton garment fabric to be bonded flat on the worktable and sets the hot press temperature and pressure parameters through the control system. Then, the hot press plate in the hot press mechanism moves downward under the drive of the drive device (such as a hydraulic rod) and contacts the fabric on the worktable. The heating element inside the hot press plate raises the temperature to the melting point of the hot melt adhesive, and at the same time applies a preset pressure, so that the fabric is bonded under the action of heat and pressure. After completion, the hot press plate returns to its original position, and the operator takes out the processed fabric to enter the next production cycle.

[0004] However, existing seamless hot press machines for cotton-padded garments have certain limitations in practical applications. Because the hot pressing process usually relies on the hot press plate to apply pressure in one direction while the worktable remains fixed, the force on the upper and lower sides of the fabric is uneven. The fabric on the side closer to the hot press plate is prone to local deformation due to excessive pressure, while the fabric on the side farther from the hot press plate may not adhere tightly due to insufficient pressure, resulting in problems such as loose adhesion and curling edges. This not only affects the strength and aesthetics of seamless splicing in cotton-padded garments, but may also increase the rework rate, reduce production efficiency, and make it difficult to meet the mass production needs of high-quality cotton-padded garments. Therefore, we propose a seamless hot press machine for cotton-padded garment production. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a seamless hot press for cotton clothing production. By making the bearing plate and the hot press plate apply clamping force to the cotton clothing fabric simultaneously, the problems in the background art can be effectively solved.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a seamless hot press for cotton clothing production, including a shell, an adjustable hot press plate at the upper end of the working chamber inside the shell, and auxiliary components;

[0007] Auxiliary components include a support plate, a lifting plate, inclined grooves, and lifting columns. The support plate is located on the lower side of the working chamber and below the hot press plate. The lower end of the outer shell has an installation cavity, and the lifting plates are all located inside the installation cavity. The bottom wall of the working chamber has symmetrically distributed clearance grooves.

The middle part of the lifting plates has an inclined groove. The installation cavity contains an adjustable lifting column, and the front and rear ends of the lifting column are located inside the adjacent inclined grooves on the front and rear sides. By making the support plate and the hot press plate apply clamping force to the cotton fabric simultaneously, the problem of uneven fabric force caused by unidirectional pressure in the prior art is solved, the tightness of the hot press part is improved, the problems of loose adhesion and curling edges are reduced, and the production quality and efficiency are improved.

[0008] Furthermore, a microcontroller is provided on the front side of the housing, and the input terminal of the microcontroller is electrically connected to an external power supply for stable control.

[0009] Furthermore, the auxiliary component also includes a mounting bracket and a guide groove. The mounting bracket is disposed on the top wall of the mounting cavity, and a guide groove is provided at the right end of the mounting bracket. The lifting column is slidably connected to the inside of the guide groove for sliding guidance.

[0010] Furthermore, the auxiliary components also include a lower pressure column, an inclined block, and an extrusion column. The inclined block is fixedly connected to the outer arc surface of the lifting column, and the extrusion column is slidably connected to the inside of a sliding hole opened in the bottom wall of the working chamber. The lower end of the extrusion column contacts the inclined surface of the left end of the inclined block, and the lower pressure column is fixedly connected to the left end of the hot press plate. The lower pressure column and the extrusion column are configured to work together for the linkage of the hot press plate.

[0011] Furthermore, the outer arc surface of the extrusion column is provided with ribs, and the left end of the mounting bracket is provided with a rib groove. The ribs and the rib groove are slidably connected. The outer arc surface of the extrusion column is provided with a reset plate, and a spring is provided between the upper side of the reset plate and the top wall of the mounting cavity for reset.

[0012] Furthermore, the working chamber is provided with evenly distributed guide columns between the upper and lower inner walls, and the hot press plate and the bearing plate are slidably connected between the guide columns. The upper side of the outer shell is provided with a hydraulic cylinder, the telescopic end of the hydraulic cylinder passes through the upper side wall of the outer shell and is fixedly connected to the upper side of the hot press plate. The inlet of the hydraulic cylinder is connected to the output port of an external hydraulic oil pump to provide guidance.

[0013] Furthermore, the hot press plate is equipped with a heating wire inside, and a temperature sensor is provided on the right side of the hot press plate. The temperature probe of the temperature sensor extends into the interior of the hot press plate. The input end of the heating wire is electrically connected to the output end of the microcontroller. The temperature sensor is bidirectionally electrically connected to the microcontroller for heating.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This seamless hot press for cotton clothing production has the following advantages:

[0015] The auxiliary components of this seamless hot press achieve synchronous clamping of the support plate and the hot press plate through a clever mechanical linkage structure. When the hot press plate moves downward, the lower pressure column squeezes the extrusion column, and through the transmission of the inclined block, lifting column and inclined groove, it drives the support plate to move upward, making the clamping force in the vertical direction more balanced. This avoids the problem of uneven fabric force caused by the unidirectional pressure of traditional hot presses, greatly improves the tightness of the hot-pressed parts of cotton clothing, improves the hot pressing efficiency, and makes the seamless hot pressing process in cotton clothing production more reliable and efficient.

[0023] Please see Figure 1-5This embodiment provides a technical solution: a seamless hot press for cotton clothing production, including a housing 1, a microcontroller 14 on the front side of the housing 1, the input end of the microcontroller 14 being electrically connected to an external power source, an adjustable hot press plate 15 on the upper end of the working cavity 4 inside the housing 1, a heating wire 11 inside the hot press plate 15, a temperature sensor 12 on the right side of the hot press plate 15, a temperature probe of the temperature sensor 12 extending into the interior of the hot press plate 15, the input end of the heating wire 11 being electrically connected to the output end of the microcontroller 14, the temperature sensor 12 being bidirectionally electrically connected to the microcontroller 14, and an auxiliary component 2;

[0024] Auxiliary component 2 includes a support plate 22, a lifting plate 23, an inclined groove 24, and lifting columns 27. The support plate 22 is located on the lower side of the working chamber 4 and below the hot press plate 15. Guide columns 9 are evenly distributed between the upper and lower inner walls of the working chamber 4. The hot press plate 15 and the support plate 22 are slidably connected between the guide columns 9. A hydraulic cylinder 13 is provided on the upper side of the outer shell 1. The telescopic end of the hydraulic cylinder 13 penetrates the upper side wall of the outer shell 1 and is fixedly connected to the upper side of the hot press plate 15. The inlet of the hydraulic cylinder 13 is connected to the outlet of an external hydraulic oil pump. An installation cavity 3 is opened at the lower end of the outer shell 1. The lifting plates 23 are all located inside the installation cavity 3. Symmetrically distributed clearance grooves 10 are opened on the bottom wall of the working chamber 4. The upper end of the lifting plate 23... All of them pass through the adjacent upper clearance groove 10 and are fixedly connected to the lower side of the bearing plate 22. The middle of the lifting plate 23 is provided with an inclined groove 24. The interior of the mounting cavity 3 is provided with an adjustable lifting column 27. The front and rear ends of the lifting column 27 are located inside the adjacent front and rear inclined grooves 24. The auxiliary component 2 also includes a mounting frame 25 and a guide groove 26. The mounting frame 25 is set on the top wall of the mounting cavity 3. The right end of the mounting frame 25 is provided with a guide groove 26. The lifting column 27 is slidably connected to the interior of the guide groove 26. The auxiliary component 2 also includes a pressing column 21, an inclined block 28 and an extrusion column 29. The inclined block 28 is fixedly connected to the outer arc surface of the lifting column 27 (the middle of the mounting frame 25 is provided with a strip-shaped opening, and the left end of the front side of the inclined block 28 is provided with a protrusion, which is connected to the strip-shaped opening). The extrusion column 29 is slidably connected to the inside of the sliding hole 16 opened in the bottom wall of the working chamber 4. The lower end of the extrusion column 29 contacts the inclined surface of the left end of the inclined block 28. The lower pressure column 21 is fixedly connected to the left end of the hot press plate 15. The lower pressure column 21 and the extrusion column 29 are matched (the positions of the lower pressure column 21 and the extrusion column 29 correspond vertically). The outer arc surface of the extrusion column 29 is provided with ribs 5. The left end of the mounting bracket 25 is provided with a rib groove 6. The ribs 5 and the rib groove 6 are slidably connected. The outer arc surface of the extrusion column 29 is provided with a reset piece 7. A spring 8 is provided between the upper side of the reset piece 7 and the top wall of the mounting chamber 3. The cotton clothing fabric and accessories (such as lining with hot melt adhesive) to be hot-pressed are laid flat on the surface of the bearing plate 22. The operator controls the single-chip microcomputer 14 on the front side of the outer casing 1. The preset hot pressing temperature is controlled by the microcontroller 14, which activates the heating wire 11 inside the hot pressing plate 15. The temperature sensor 12 monitors the temperature of the hot pressing plate 15 in real time and feeds it back to the microcontroller 14 to ensure that the temperature remains stable within the set range. The external hydraulic oil pump is activated, driving the hot pressing plate 15 downward along the guide column 9 via the hydraulic cylinder 13. During the downward movement of the hot pressing plate 15, the lower pressing column 21 at its left end moves downward synchronously. After a period of time, it contacts and squeezes the extrusion column 29. The extrusion column 29 slides downward along the sliding hole 16 (the ribs 5 of the extrusion column 29 slide along the rib groove 6 to ensure stable vertical movement, and the spring 8 is stretched by the reset plate 7). Its lower end squeezes the inclined surface at the left end of the inclined block 28, forcing the inclined block 28 to drive the lifting column 27 to slide to the right along the guide groove 26 of the mounting bracket 25.The front and rear ends of the lifting column 27 are embedded in the inclined grooves 24 of the lifting plate 23. When it slides to the right, the inclined surface of the inclined groove 24 pushes the lifting plate 23 upward. The lifting plate 23 drives the bearing plate 22 to move upward along the guide column 9, and cooperates with the hot press plate 15 to apply clamping force to the fabric in the middle. At this time, the heat generated by the heating wire 11 is transferred to the fabric, causing the hot melt adhesive to melt. Under the combined action of pressure and heat, the fabric is bonded. After a period of hot pressing is completed, the hydraulic cylinder 1 is controlled by the external hydraulic oil pump. 3. The hot press plate 15 is driven to reset upwards, the lower pressure column 21 releases pressure on the extrusion column 29, the spring 8 releases its elastic force, and pushes the reset plate 7 to drive the extrusion column 29 to reset upwards. After the inclined block 28 loses its extrusion, the lifting plate 23 and the bearing plate 22 reset downwards under the action of gravity. The guide groove 26 of the lifting plate 23 squeezes the lifting column 27 to slide to the left along the guide groove 26 to reset, waiting for the next operation. Through the linkage of the mechanical structure, the bearing plate 22 and the hot press plate 15 are synchronously clamped, improving the quality and efficiency of hot pressing of cotton clothing.

[0025] The working principle of the seamless hot press machine for cotton clothing production provided by this utility model is as follows: The cotton clothing fabric and accessories (such as lining with hot melt adhesive) to be hot pressed are laid flat on the surface of the bearing plate 22. The operator presets the hot pressing temperature through the single-chip microcomputer 14 on the front side of the outer shell 1. The single-chip microcomputer 14 controls the heating wire 11 inside the hot press plate 15 to start. The temperature sensor 12 monitors the temperature of the hot press plate 15 in real time and feeds it back to the single-chip microcomputer 14 to ensure that the temperature is stable within the set range. The external hydraulic oil pump starts and drives the hot press plate 15 to move downward along the guide column 9 through the hydraulic cylinder 13. During the downward movement of the hot press plate 15, the lower pressing column 21 at its left end moves downward synchronously. After a period of time, it contacts and squeezes the extrusion column 29. The extrusion column 29 slides downward along the sliding hole 16 (the rib 5 of the extrusion column 29 slides along the rib groove 6 to ensure stable vertical movement, and the spring 8 is stretched by the reset plate 7). Its lower end squeezes the inclined surface at the left end of the inclined block 28, forcing the inclined block 28 to drive the lifting column 27. Sliding to the right along the guide groove 26 of the mounting bracket 25, the front and rear ends of the lifting column 27 are embedded in the inclined groove 24 of the lifting plate 23. When it slides to the right, the inclined surface of the inclined groove 24 pushes the lifting plate 23 to move upward. The lifting plate 23 drives the bearing plate 22 to move upward along the guide column 9, and cooperates with the hot press plate 15 to apply clamping force to the fabric in the middle. At this time, the heat generated by the heating wire 11 is transferred to the fabric, causing the hot melt adhesive to melt. Under the combined action of pressure and heat, the fabric is bonded. After a period of hot pressing is completed, the hydraulic cylinder 13 is controlled by the external hydraulic oil pump to drive the hot press plate 15 to reset upward. The lower pressure column 21 releases the pressure on the extrusion column 29, the spring 8 releases its elastic force, and pushes the reset piece 7 to drive the extrusion column 29 to reset upward. After the inclined block 28 loses its extrusion, the lifting plate 23 and the bearing plate 22 reset downward under the action of gravity. The guide groove 26 of the lifting plate 23 squeezes the lifting column 27 to slide to the left along the guide groove 26 to reset, waiting for the next operation.

[0026] It is worth noting that the heating wire 11 disclosed in the above embodiments can be a nickel-chromium alloy heating wire, the temperature sensor 12 can be a DS18B20, the hydraulic cylinder 13 can be a conventional hydraulic cylinder, and the microcontroller 14 can be an STC89C52. The microcontroller 14 controls the operation of the heating wire 11 and the temperature sensor 12 using methods commonly used in the prior art.
