Description

Technical Field

[0001] This application relates to the field of glove manufacturing technology, and in particular to a hot air shaping device for cut-resistant gloves. Background Technology

[0002] With the increasing demand for safety protection for workers and users in fields such as industrial manufacturing, outdoor sports, and emergency rescue, gloves that combine cut resistance and warmth have become a focus of market attention. Fully formed cut-resistant and warm knitted gloves utilize a process that combines high-strength cut-resistant fibers with warm materials to create a seamless, highly fitted glove structure. These gloves not only need to meet international cut-resistant standards but also maintain hand flexibility and continuous warmth in low-temperature environments.

[0003] However, the fully knitted process leads to problems such as uneven local stress and poor dimensional stability in gloves after production. In particular, wrinkles or deformation are prone to occur in the composite area of ​​the cut-resistant layer and the insulation layer, which directly affects the protective performance and wearing comfort. Therefore, it needs to be improved. Utility Model Content

[0004] To address the problem of wrinkled or deformed gloves after production, this application provides a hot air shaping device for cut-resistant gloves.

[0005] The hot air shaping device for cut-resistant gloves provided in this application adopts the following technical solution: A hot air shaping device for cut-resistant gloves includes a frame with a shaping box mounted on the frame. The shaping box has an inlet and an outlet at both ends. Inside the shaping box is a transmission mechanism for transferring glove molds. A hot air mechanism and a heating plate are mounted on the top of the shaping box. The heating plate is positioned above the transmission mechanism. The hot air mechanism includes a fan and an air supply duct. The air supply duct extends toward the transmission mechanism, and its outlet is directly opposite the glove mold on the transmission mechanism.

[0006] Because the full-form knitting process causes uneven local stress and poor dimensional stability in gloves after production, especially in the composite area of ​​the cut-resistant layer and the thermal insulation layer, wrinkles or deformation are easily generated, which directly affects the protective performance and wearing comfort. By adopting the above technical solution, including a frame, a shaping box is installed on the frame, a transmission mechanism is installed inside the shaping box, and a hot air mechanism and a heating plate are installed inside the shaping box. The hot air mechanism includes a fan and an air supply duct. When shaping the produced gloves, the gloves to be shaped are placed into the glove mold. The heating plate temperature is set according to the glove material characteristics, the fan frequency is adjusted, and the air velocity at the outlet of the air supply duct is controlled to ensure that the hot air penetrates the thickness of the glove. At the same time, the stroke of the lifting cylinder is set to ensure the distance between the heating plate and the upper surface of the mold. The drive motor is started, and the drive motor drives the conveyor belt to run. The glove molds enter the shaping box in sequence. When the mold passes through the inlet end curtain, the curtain automatically pops open and resets to reduce heat loss. The mold enters the hot air area of ​​the shaping box. The hot air mechanism blows hot air onto the surface of the glove through the air supply ducts on both sides, which quickly raises the overall temperature of the glove. The heating plate is lowered under the drive of the lifting cylinder to further heat and shape the glove. At this time, the hot air continues to penetrate the inside of the glove to eliminate the stress between the composite layers. The mold is shaped in the shaping box for a sufficient time to maintain a stable temperature and ensure that the glove size is solidified. After the shaping is completed, the mold returns to the beginning of the conveyor belt. The finished product is manually demolded or removed by a robotic arm and the equipment is reused. By incorporating a shaping box, heating mechanism, and heating plate, the hot air mechanism utilizes the penetrability of hot air to eliminate internal stress in the composite area of ​​the cut-resistant layer and the insulation layer, reducing the likelihood of wrinkles or deformation in the gloves during subsequent use. At the same time, the heating plate further solidifies the three-dimensional structure of the gloves, ensuring that the gloves can maintain their preset shape for a long time during subsequent use, effectively improving the quality of the finished product.

[0007] Optionally, baffles are provided on both sides of the inner wall of the shaping box. The baffles are arranged along the transmission direction of the transmission mechanism, and a notch is provided on the baffle for the air supply duct to pass through.

[0008] By adopting the above technical solution, two baffles are installed on both sides of the inner wall of the shaping box, and notches are opened on the baffles. Through the setting of baffles and notches, the baffles effectively restrict the hot air diffusion range, prevent heat loss to non-shaping areas, and ensure that the hot air is concentrated on the surface of the glove mold. At the same time, the notches ensure the interference-free installation of the air supply duct, making the structure more compact.

[0009] Optionally, the shaping box is provided with support columns for supporting the baffle, and there are multiple support columns, with the baffle connected to the multiple support columns.

[0010] By adopting the above technical solution, the baffle is fixed inside the shaping box by multiple support columns; the multiple support columns form a rigid support, which prevents the baffle from deforming due to uneven local stress and enhances the connection strength of the baffle.

[0011] Optionally, the hot air mechanism is in the form of four sets, with the four air supply pipes symmetrically distributed on both sides of the transmission mechanism, and each baffle corresponding to two air supply pipes.

[0012] By adopting the above technical solution, the number of hot air mechanisms is four. By setting the number of hot air mechanisms, the hot air mechanisms form a cross hot air field, which effectively eliminates the shaping blind spot in the composite area of ​​the anti-cut layer and the insulation layer, enhances the heat energy utilization rate, and improves the uniformity of glove shaping.

[0013] Optionally, the shaping box is equipped with curtains at both the inlet and outlet ends, and an openable observation window is provided on the side panel of the shaping box.

[0014] By adopting the above technical solution, the baffle is installed at the inlet and outlet of the shaping box, and the observation window can be opened and closed on the side panel of the shaping box. Through the setting of the baffle and the observation window, the baffle can effectively block the air convection inside and outside the shaping box, reduce the loss of hot air, and maintain a constant temperature environment inside the box. At the same time, the observation window on the side panel can be opened and closed to observe the shaping status of the gloves when the equipment is running, and can also be manually intervened or maintained when needed.

[0015] Optionally, the transmission mechanism includes a drive roller, a driven roller, a conveyor belt, and a drive motor. The drive roller and the driven roller are rotatably connected to both ends of the shaping box, and both ends of the conveyor belt are tensioned on the drive roller and the driven roller, respectively. The output end of the drive motor is connected to the drive roller, and the glove mold is fixed to the surface of the conveyor belt at equal intervals.

[0016] By adopting the above technical solution, the transmission mechanism includes an active roller, a driven roller, a conveyor belt, and a drive motor; through the setting of the transmission mechanism, continuous conveying of glove molds is realized, ensuring that the dwell time of each mold in the hot air setting zone is highly consistent with the height of the heated position.

[0017] Optionally, the heating plate is located directly above the transmission mechanism, and a lifting cylinder is provided on the top of the shaping box. The lifting cylinder is vertically arranged inside the shaping box, and the frame of the heating plate is connected to the piston end of the lifting cylinder.

[0018] By adopting the above technical solution, the lifting cylinder is installed in the shaping box, and the heating plate is raised and lowered by the lifting cylinder. The lifting cylinder enables the adjustment of the distance between the heating plate and the glove mold on the transmission mechanism. The lifting cylinder can adjust the height of the heating plate in real time according to the glove process requirements, ensuring that the gloves can maintain the preset shape for a long time in subsequent use.

[0019] Optionally, the number of lifting cylinders is multiple sets, and the multiple sets of lifting cylinders are respectively arranged at each corner of the heating plate frame.

[0020] By adopting the above technical solution, the number of lifting cylinders is multiple sets; by setting multiple sets of lifting cylinders, the heating plate is driven to rise and fall synchronously, avoiding tilting caused by uneven force at a single point, ensuring that the heating plate and the glove mold on the transmission mechanism always remain parallel, and ensuring that the heating and force of each part are consistent during the shaping process.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a shaping box, heating mechanism and heating plate, the hot air mechanism uses the penetrability of hot air to eliminate the internal stress in the composite area of ​​the cut-resistant layer and the insulation layer, reducing the occurrence of wrinkles or deformation in the gloves during subsequent use. At the same time, the heating plate further solidifies the three-dimensional structure of the gloves, ensuring that the gloves can maintain the preset shape for a long time during subsequent use, effectively improving the quality of the finished product. 2. By setting baffles and notches, the baffles effectively restrict the hot air diffusion range, prevent heat loss to non-shaped areas, and ensure that the hot air is concentrated on the surface of the glove mold. At the same time, the notches ensure the interference-free installation of the air supply duct, making the structure more compact. 3. With the setting of curtains and observation windows, the curtains can effectively block the air convection inside and outside the setting box, reduce the loss of hot air, and maintain a constant temperature environment inside the box. At the same time, the observation windows on the side panels can be opened and closed to observe the setting status of the gloves when the equipment is running, and can also be manually intervened or maintained when needed.

Detailed Implementation

[0025] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0026] This application discloses a hot air shaping device for cut-resistant gloves. (Refer to...) Figure 1 The hot air shaping device for cut-resistant gloves includes a frame 1, on which a shaping box 2 is installed. The shaping box 2 has a hollow structure inside, and inlet and outlet are formed at both ends of the shaping box 2. In this embodiment, the shaping box 2 is used to shape the gloves after they have been produced.

[0027] Reference Figure 1 and Figure 2The shaping box 2 is equipped with a transmission mechanism 3, which is arranged along the length of the shaping box 2. In this embodiment, a glove mold 4 is installed on the transmission mechanism 3. There are multiple glove molds 4. The formed gloves are put on the glove mold 4 and are driven into the shaping box 2 by the transmission mechanism 3.

[0028] Reference Figure 1 and Figure 2 The transmission mechanism 3 includes a drive roller 31, a driven roller 32, a conveyor belt 33, and a drive motor 34. The drive roller 31 and the driven roller 32 are rotatably connected to both ends of the shaping box 2. The drive roller 31 and the driven roller 32 can be installed with the shaping box 2 through bearings. The two ends of the conveyor belt 33 are tensioned on the drive roller 31 and the driven roller 32, respectively. The output end of the drive motor 34 is connected to the drive roller 31. The glove molds 4 are fixed at equal intervals on the surface of the conveyor belt 33. The transmission mechanism 3 realizes the continuous conveying of the glove molds 4, ensuring that the residence time of each mold in the hot air shaping zone is consistent with the height of the heated position.

[0029] Reference Figure 1 The shaping box 2 is equipped with curtains 9 at both the inlet and outlet ends. The shaping box 2 is equipped with two openable observation windows 10 on its side panels. The curtains 9 can effectively block the air convection inside and outside the shaping box 2, reduce the loss of hot air, and maintain a constant temperature environment inside the box. At the same time, the openable observation windows 10 on the side panels can be used to observe the shaping status of the gloves when the equipment is running, and can also be used for manual intervention or maintenance when needed.

[0030] Reference Figure 1 and Figure 2 The shaping box 2 is equipped with a hot air mechanism 5 and a heating plate 6. Both the hot air mechanism 5 and the heating plate 6 are located on the top of the shaping box 2. The hot air mechanism 5 includes a fan 51 and an air supply duct 52. The fan 51 is installed on the top of the shaping box 2. The hot air outlet of the fan 51 is connected to the air supply duct 52. The air supply duct 52 extends toward the conveyor belt 33 of the transmission mechanism 3. The outlet end of the air supply duct 52 is directly opposite the glove mold 4 on the transmission mechanism 3.

[0031] Reference Figure 2 The inner walls of the shaping box 2 are also equipped with baffles 7 on both sides. The two baffles 7 are arranged opposite each other, and each baffle 7 is arranged along the transmission direction of the transmission mechanism 3. A notch 71 is opened through the baffle 7 to allow the air supply duct 52 to pass through. The baffle 7 effectively restricts the hot air diffusion range, prevents heat loss to the non-shaping area, and ensures that the hot air is concentrated on the surface of the glove mold 4. At the same time, the notch 71 ensures the interference-free installation of the air supply duct 52, making the structure more compact.

[0032] Reference Figure 2The shaping box 2 has multiple support columns 8 installed inside, and the baffle 7 is fixedly connected to the multiple support columns 8; the multiple support columns 8 form a rigid support, which prevents the baffle 7 from deforming due to uneven local stress and enhances the connection strength of the baffle 7.

[0033] Reference Figure 2 In this embodiment, there are four sets of hot air mechanisms 5. Four air supply pipes 52 are symmetrically distributed on both sides of the transmission mechanism 3. Each baffle 7 corresponds to two air supply pipes 52. There are two notches 71 on each baffle 7. The four sets of hot air mechanisms 5 form a cross hot air field, which effectively eliminates the shaping blind zone of the composite area of ​​the anti-cutting layer and the insulation layer, enhances the heat energy utilization rate, and improves the uniformity of glove shaping.

[0034] Reference Figure 2 The heating plate 6 is arranged above the transmission mechanism 3. In this embodiment, the heating plate 6 itself has a corresponding heat source. A lifting cylinder 11 is installed on the top of the shaping box 2. The lifting cylinder 11 is used to drive the heating plate 6 to rise and fall. The lifting cylinder 11 is arranged vertically inside the shaping box 2. The frame of the heating plate 6 is connected to the piston end of the lifting cylinder 11. In this embodiment, the outer cylinder body of the lifting cylinder 11 is made of high temperature resistant material and is not affected by the heating plate 6. The lifting cylinder 11 realizes the adjustment of the distance between the heating plate 6 and the glove mold 4 on the transmission mechanism 3. The lifting cylinder 11 can adjust the height of the heating plate 6 in real time according to the glove process requirements to ensure that the gloves can maintain the preset shape for a long time in subsequent use.

[0035] Reference Figure 2 Meanwhile, there are multiple sets of lifting cylinders 11, which are respectively set at each corner of the frame of the heating plate 6. Preferably, there are six lifting cylinders 11. The heating plate 6 is driven to rise and fall synchronously to avoid tilting caused by uneven force at a single point, and to ensure that the heating plate 6 and the glove mold 4 on the transmission mechanism 3 always remain parallel, so as to ensure that the heating and force of each part are consistent during the shaping process.

[0036] The implementation principle of the hot air shaping device for cut-resistant gloves in this embodiment is as follows: When shaping the produced gloves, the gloves to be shaped are placed into the glove mold 4. The temperature of the heating plate 6 is set according to the characteristics of the glove material, the frequency of the fan 51 is adjusted, and the outlet air speed of the air supply pipe 52 is controlled to ensure that the hot air penetrates the thickness direction of the glove. At the same time, the stroke of the lifting cylinder 11 is set to ensure the distance between the heating plate 6 and the upper surface of the mold. The drive motor 34 is started, and the drive motor 34 drives the conveyor belt 33 to run. The glove mold 4 enters the shaping box 2 in sequence. When the mold passes through the inlet end baffle 9, the baffle... Curtain 9 automatically opens and resets to reduce heat loss. The mold enters the hot air area of ​​the shaping box 2. The hot air mechanism 5 blows hot air onto the glove surface through the air supply pipes 52 on both sides, quickly raising the overall temperature of the glove. The heating plate 6 descends under the drive of the lifting cylinder 11 to further heat and shape the glove. At this time, the hot air continuously penetrates the inside of the glove, eliminating the stress between the composite layers. The mold is shaped in the shaping box 2 for a sufficient time to maintain a stable temperature and ensure that the glove size is solidified. After the shaping is completed, the mold returns to the starting end of the conveyor belt 33. The finished product can be manually demolded or removed by the robotic arm and reused. With the setting of the shaping box 2, heating mechanism and heating plate 6, the hot air mechanism 5 uses the penetrability of hot air to eliminate the internal stress in the composite area of ​​the cut-resistant layer and the heat insulation layer, reducing the occurrence of wrinkles or deformation in the gloves during subsequent use. At the same time, the heating plate 6 further solidifies the three-dimensional structure of the gloves, ensuring that the gloves can maintain the preset shape for a long time during subsequent use, effectively improving the quality of the finished product.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
