Description

Technical Field

[0001] This utility model relates to the field of hat manufacturing technology, specifically to a hot and cold setting device for hat manufacturing. Background Technology

[0002] As an important clothing accessory, the shaping process in hat manufacturing directly determines the product's aesthetics, comfort, and lifespan. A hat heat-setting device is a specialized thermoplastic processing equipment used in hat manufacturing. Through a physical process of heating to soften and cooling to solidify, it allows the hat material (usually textiles, felt, or synthetic fibers) to acquire and maintain a specific three-dimensional shape. This device plays a crucial role in the hat-making process, directly determining the hat's appearance, wearing comfort, and dimensional stability.

[0003] Currently, most hat-making cold and hot setting devices lack sufficient mold fixation and adjustment capabilities. Most setting devices use spring clamps to fix hats, which can cause wobbling when subjected to additional force, making it impossible to guarantee clamping stability. In addition, traditional equipment molds are mostly fixed designs, requiring the removal of bolts and other fasteners for replacement, resulting in long mold change times and severely restricting the flexibility of multi-variety production. Utility Model Content

[0004] The purpose of this invention is to provide a hot and cold setting device for hat making to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hot and cold setting device for hat making, comprising a body, a support member rotatably connected inside the body, a lower mold detachably mounted on the top of the support member, a hot air delivery pipe inserted inside the support member, the lower mold having a hollow internal structure, a cavity provided at the top of the body, the lower mold located in the cavity, a first electric push rod installed inside the body above the lower mold, a positioning frame installed at the bottom end of the first electric push rod, two top frames slidably mounted on the bottom of the positioning frame, the two top frames being arranged opposite each other, side clamps being installed at the bottom edges of the two top frames, and a cold air delivery pipe being provided on one side of each of the two side clamps.

[0006] Preferably, the front end of the machine body is hinged with two opening and closing doors. The opening and closing doors mainly serve the functions of safety protection and heat preservation. When closed during operation, they can prevent burns caused by high-temperature internal components, maintain a stable temperature inside the cavity, reduce heat loss, save energy, and facilitate the operator to observe the internal working status and load and unload materials.

[0007] Preferably, a toothed ring is provided at the bottom edge of the outer surface of the support member, and a first drive gear is meshed with one side of the toothed ring. The first drive gear is driven to rotate by an external motor. Through gear meshing, the power transmission to rotate the toothed ring and the support member fixed thereto is smooth and the rotation speed is easy to control.

[0008] Preferably, the top of the support member is provided with a threaded section, the bottom of the lower mold is provided with a threaded hole at the middle position, and the circumferential surface of the lower mold is provided with several ventilation holes. The lower mold can be installed and disassembled by screwing, the connection is firm and will not loosen due to rotation, and the ventilation holes allow the hot air inside the lower mold to be smoothly discharged and penetrate the cap material.

[0009] Preferably, racks are provided at the opposite side edges of the two top frames. The two racks are designed to face each other and are connected by a second drive gear. The second drive gear is rotatably connected to the bottom of the positioning frame. When the second drive gear is driven to rotate by a motor, it will simultaneously drive the racks on both sides to move in opposite directions at the same speed. This forces the two top frames to move towards or away from each other synchronously, ensuring that the two side clamps always clamp or release the cap at the same speed and in a centered manner. This avoids cap deformation caused by unilateral compression and ensures high clamping accuracy.

[0010] Preferably, a fixed upright is provided at the top of each of the two top frames near the corresponding side clamp position. An adjusting rod is hinged to the fixed upright and the corresponding side clamp. A second electric push rod is connected to the adjusting rod and the corresponding top frame. The output end of the second electric push rod is slidably connected to the adjusting rod. The extension and retraction of the second electric push rod will push the adjusting rod to move around its hinge point. One end of the adjusting rod is hinged to the fixed upright, and the other end is hinged to the side clamp. This movement will be converted into the rotation of the side clamp around its hinge point with the bottom of the top frame, thereby dynamically changing the tilt angle of the side clamp. This allows the side clamp to not only move horizontally but also change its angle, thus perfectly conforming to the curves of different brims, from flat-brimmed hats to baseball caps with large curved brims, achieving three-dimensional adaptive wrapping and clamping, and further expanding the processing range of the equipment.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This hat-making device uses a hot and cold setting mechanism. It features a relatively movable top frame and hinged side clamps. The side clamps can be adjusted in angle. The lower mold is detachably connected to the support component via a threaded section, making replacement easy. The same equipment can adapt to the production needs of various hat styles. The device can adapt to different brim curves, ensuring three-dimensional wrapping and clamping, shortening mold change time, and improving production efficiency. Attached Figure Description

[0016] like Figures 1 to 4As shown, the hot and cold setting device for hat making in this embodiment includes a body 1. The body 1 serves as the basic frame and outer shell of the entire device, providing structural support and protecting the internal mechanical components. A support member 9 is rotatably connected inside the body 1. A lower mold 4 is detachably mounted on the top of the support member 9. The support member 9 can drive the lower mold 4 and the hat to rotate together. During the heat setting stage, this allows the hat to receive heat from the hot air delivery pipe 11 evenly and without dead angles, avoiding the problems of local overheating or uneven heating, significantly improving the setting quality, and allowing for quick changes to different sizes. The lower mold 4, or a different shape, allows the same machine to produce various styles of hats, greatly enhancing the flexibility of the equipment and meeting the needs of small-batch, multi-variety production. A hot air delivery pipe 11 is inserted inside the support component 9. The lower mold 4 has a hollow internal structure, and the hot air delivery pipe 11 directly introduces hot air into the hollow lower mold 4. The heat flow penetrates from the inside of the mold outwards, passing through the mold wall and the hat material, achieving uniform heating from the inside out, resulting in high thermal efficiency and better shaping effect. A cavity is provided at the top of the machine body 1, and the lower mold 4 is located in the cavity. The machine above the lower mold 4... The body 1 is equipped with a first electric push rod 16, which serves as the main drive source and is responsible for the vertical movement of the entire upper pressing mechanism. The first electric push rod 16 drives the positioning frame 14 to descend, causing the side clamps 2 to contact the cap and complete the mold closing action. After the shaping is completed, the positioning frame 14 is raised to remove the cap. The positioning frame 14 is installed at the bottom end of the first electric push rod 16. Two top frames 12 are slidably installed at the bottom of the positioning frame 14. The two top frames 12 are positioned opposite each other, and the side clamps 2 are installed at the bottom edges of the two top frames 12. The two top frames 12 can slide relative to each other. This adjusts the horizontal distance between the two side clips 2. The side clips 2 are connected to the top frame 12 by a hinge, so that they can generate a certain angle of self-adaptation when in contact with the side of the hat, ensuring good fit with the brim or body of the hat with different tapers and providing uniform clamping force. Each side of the two side clips 2 is provided with a cold air delivery pipe 13. After heat setting, the cold air delivery pipe 13 sprays cold air to quickly cool the hat that has been softened by heat. Since the side clips 2 are close to the side of the hat, the cold air can act directly and efficiently on the hat, so that it can be quickly set, shorten the production cycle, and stabilize the molding effect.

[0017] Specifically, the front end of the machine body 1 is hinged with two opening and closing doors 3. The opening and closing doors 3 mainly serve the functions of safety protection and heat preservation. When closed during operation, they can prevent burns caused by high-temperature internal components, maintain a stable temperature inside the cavity, reduce heat loss, save energy, and facilitate the operator to observe the internal working status and load and unload materials.

[0018] Furthermore, a toothed ring 8 is provided at the bottom edge of the outer surface of the support member 9. A first drive gear 7 is meshed with one side of the toothed ring 8. The first drive gear 7 is driven to rotate by an external motor. Through gear meshing, the toothed ring 8 and the support member 9 fixed thereto rotate. The power transmission is smooth and the rotation speed is easy to control.

[0019] Furthermore, the top of the support member 9 is provided with a threaded section 10, and the bottom of the lower mold 4 is provided with a threaded hole 6. Several ventilation holes 5 are provided through the circumferential surface of the lower mold 4. The lower mold 4 can be installed and disassembled by screwing. The connection is firm and will not loosen due to rotation. The ventilation holes 5 allow the hot air inside the lower mold 4 to be smoothly discharged and penetrate the cap material.

[0020] Furthermore, racks are provided at the opposite side edges of the two top frames 12. The two racks are designed to face each other and are connected to a second drive gear 15. The second drive gear 15 is rotatably connected to the bottom of the positioning frame 14. When the second drive gear 15 is driven to rotate by a motor, it will simultaneously drive the racks on both sides to move in opposite directions at the same speed. This forces the two top frames 12 to move towards or away from each other synchronously, ensuring that the two side clamps 2 always clamp or release the cap at the same speed and in a centered manner, avoiding cap deformation caused by unilateral compression, and achieving high clamping accuracy.

[0021] Furthermore, each of the two top frames 12 is equipped with a fixed upright 17 near the corresponding side clamp 2. An adjusting rod 19 is hinged between the fixed upright 17 and the corresponding side clamp 2. A second electric push rod 18 is connected between the adjusting rod 19 and the corresponding top frame 12. The output end of the second electric push rod 18 is slidably connected to the adjusting rod 19. The extension and retraction of the second electric push rod 18 will push the adjusting rod 19 to move around its hinge point. One end of the adjusting rod 19 is hinged to the fixed upright, and the other end is hinged to the side clamp 2. This movement will be converted into the rotation of the side clamp 2 around its hinge point with the bottom of the top frame 12, thereby dynamically changing the tilt angle of the side clamp 2. This allows the side clamp 2 to not only move horizontally but also change its angle, thus perfectly fitting the curves of different hat brims, from flat-brimmed hats to baseball caps with large curved brims, achieving three-dimensional adaptive wrapping and clamping, further expanding the processing range of the equipment.

[0022] The usage method of this embodiment is as follows: Before using the hot and cold setting device for hat making, select a suitable lower mold 4 according to the style and size of the hat to be processed. Align the threaded hole 6 at the bottom of the lower mold 4 with the threaded section 10 at the top of the support 9 and tighten it to securely install it on the support 9. Close the opening and closing door 3, start the equipment, and the hot air delivery pipe 11 begins to deliver hot air into the system to preheat the lower mold 4, preparing it for the heat setting process. After preheating is completed, open the opening and closing door 3 and put the softened hat blank (usually pre-moistened) on the mold. On the preheated lower mold 4, the first electric push rod 16 is activated by the control system, pushing the positioning frame 14 and the entire side clamp 2 mechanism below it to move downwards. Simultaneously with the descent of the positioning frame 14, the motor driving the second drive gear 15 is activated. Through rack and pinion transmission, the two top frames 12 move synchronously towards each other, clamping the brim horizontally. The second electric push rod 18 operates, pushing the adjusting rod 19 to drive the side clamp 2 to rotate around its bottom hinge point, ensuring its angle perfectly matches the curved surface of the brim, achieving three-dimensional wrapping. After mold closing, The motor driving the first drive gear 7 starts, which in turn drives the support 9, the lower mold 4, and the clamped hat to rotate at a uniform speed. At the same time, the hot air delivery pipe 11 continuously delivers hot air into the hollow lower mold 4. The heat penetrates evenly into every part of the hat, inside and out, through the vents 5 on the mold wall, softening the material and shaping it into the mold shape. After the preset heat setting time is reached, the system automatically cuts off the hot air supply and stops the rotation of the support 9. The cold air delivery pipe 13 immediately opens, blowing air onto the hat tightly wrapped by the side clamp 2. Cold air is supplied. Since the cap is still clamped and the cold air acts directly on the surface, it can quickly remove heat, solidify the material, and permanently fix its shape obtained in the heat setting stage. After the cooling process is completed, the second electric push rod 18 retracts first, causing the side clamp 2 to return to its initial angle. Then, the second drive gear 15 rotates in the opposite direction, driving the two top frames 12 to move in opposite directions, and the side clamp 2 releases the cap. Finally, the first electric push rod 16 retracts, driving the entire upper mechanism to rise and reset. The operator opens the opening and closing door 3 and removes the shaped cap from the lower mold 4. Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
