Description
Technical Field
[0001] The utility model relates to the technical field of shoe upper processing, in particular to a high-frequency heat sealing machine used for shoe upper processing. Background Art
[0002] In the footwear manufacturing industry, the processing quality of the shoe upper is directly related to the comfort, aesthetics and durability of the shoes. As consumers' requirements for product quality continue to increase, high-frequency heat sealing machines, as an advanced processing equipment, have demonstrated their unique advantages in the field of shoe upper processing.
[0003] The working principle of the high-frequency heat sealing machine is based on the effect of high-frequency electric field. When high-frequency current passes through the electrodes, a strong alternating electric field will be generated between the two poles. This high-frequency electric field can quickly penetrate the surface of non-conductive materials, causing the polar molecules inside the material (such as water molecules) to vibrate at high frequency, thereby generating heat. Since the heat is generated from within the material rather than conducted by an external heat source, the heating efficiency is extremely high and the heating is uniform, making it suitable for rapid heat sealing of thin materials such as shoe uppers.
[0004] The high-frequency heat sealing machine uses the heat generated by the high-frequency electric field to make the upper material (such as PVC, TPU, leather, etc.) reach the melting point at the contact surface, thereby achieving seamless heat sealing or welding. No adhesives are required, which reduces the use of chemicals and improves the environmental friendliness of the product. At the same time, the heat-sealed materials are firmly connected and have a smooth appearance, meeting the requirements of footwear products for aesthetics and durability.
[0005] However, in the existing process of processing shoe uppers using high-frequency heat sealing machines, dust and other impurities in the working environment will affect the heat sealing effect, resulting in loose adhesion of the shoe uppers, bubbles, and even being burned and embedded in the shoe uppers under high temperature and high pressure.

[0035] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.
[0036] In this application, terms such as "upper," "inner," "outer," and "middle" indicate positions or locations based on those shown in the accompanying drawings. These terms are intended to better describe this application and its embodiments and are not intended to limit the devices, elements, or components indicated to specific positions, or to their construction or operation in a specific position.
[0037] like Figure 1-3 As shown, a high-frequency heat sealing machine for shoe upper processing comprises a heat sealing machine body, with a dust cover 1 connected to the outside of the heat sealing machine body. The heat sealing machine body comprises a machine body 3, to which an upper electrode plate 4 is longitudinally slidably connected. A mold 5 is connected to the lower end of the upper electrode plate 4 and is detachably connected to the upper electrode plate 4. A lower electrode plate 6 is provided at the lower end of the mold 5 and is fixedly connected to the machine body 3. An anti-slip layer 7 is attached to the lower electrode plate 6. This ensures the stability of the shoe upper material during the heat sealing process. A loading conveyor belt 8 is provided at one end of the lower electrode plate 6. A feed port 9 is provided on the dust cover 1 corresponding to the loading conveyor belt 8. A unloading conveyor belt 10 is provided on one side of the lower electrode plate 6. A discharge port 12 is provided on the dust cover 1 corresponding to the unloading conveyor belt 10. A baffle 11 is connected to the side of the unloading conveyor belt 10 away from the lower electrode plate 6. This prevents the shoe upper material from falling during transportation. Both the loading conveyor belt 8 and the unloading conveyor belt 10 are provided with multiple ventilation holes 13. These facilitate air circulation, reduce the impact of heat generated during the heat sealing process on the conveyor belts, and aid in heat dissipation. An observation window 2 is connected to the dust cover 1 corresponding to the machine body 3. This allows operators to monitor the operating status of the heat sealer in real time without opening the dust cover 1, and adjust operating parameters to avoid heat sealing problems with the upper material.
[0038] like Figure 4 As shown, the upper end of the feeding conveyor belt 8 is connected to a dust hood 14, and the upper end of the dust hood 14 is connected to a first cylinder 15. The piston rod end of the first cylinder 15 is connected to a dust collection device 16, which is longitudinally slidably connected within the dust collection hood 14. The shoe upper material to be processed is then placed on the feeding conveyor belt 8, which drives the shoe upper material forward. The first cylinder 15 is then activated to control the height of the dust collection device 16, effectively adsorbing the surface of the shoe upper material, removing dust and debris from the shoe upper material, and improving the heat sealing quality. A material receiving box 23 is slidably connected within the feeding conveyor belt 8. The material receiving box 23 can collect debris that falls from the shoe upper material during the vacuuming process, keeping the production line clean.
[0039] like Figure 5 and Figure 6 As shown, a transmission chain 17 is connected to the side of the machine body 3 away from the unloading conveyor belt 10, and a material diverting device is connected to the transmission chain 17. The material diverting device includes a connecting frame 18, which is fixedly connected to the transmission chain 17. The upper end of the connecting frame 18 is connected to a second cylinder 19, and the end of the piston rod of the second cylinder 19 is connected to the diverting frame 20. A pusher plate 21 is vertically arranged on the diverting frame 20, and the pusher plate 21 is connected to the piston rod of a third cylinder 22, which is fixedly connected to the diverting frame 20. When the loading conveyor belt 8 transports the upper material to the vicinity of the diverting frame 20, that is, the initial working position of the diverting frame 20, the second cylinder 19 is activated, pushing the diverting frame 20 downward, placing the upper material inside the diverting frame 20. At this time, the third cylinder 22 remains in a retracted state, and the pusher plate 21 does not push. Then, the transmission chain 17 pushes the upper material to the predetermined position below the mold 5, that is, the predetermined working position of the material diverter 20, through the material diverter 20. Then, the upper electrode plate 4 slides down longitudinally with the mold 5 under the control of the machine body 3 until the mold 5 is in close contact with the lower electrode plate 6, and the upper material is subjected to high-frequency heat sealing treatment. The frequency energy is transmitted to the material through the upper and lower electrode plates 6, causing the upper material to melt and bond at a specific position to form a firm connection. At the same time, the material diverter 20 moves to the initial working position through the transmission chain 17. After the high-frequency heat sealing treatment of the upper material is completed, the upper electrode plate 4 rises back to its original position, and the upper material is cooled to ensure that the heat-sealed part is fully solidified. The material diverter 20 moves to the predetermined working position through the transmission chain 17, and then the third cylinder 22 is started, pushing the push plate 21 to move horizontally, pushing the upper material onto the unloading conveyor belt 10.
[0040] The working process of this utility model is:
[0041] First, the upper material to be processed is placed on the feeding conveyor 8, which then drives the upper material forward. The first cylinder 15 then activates to control the height of the dust collector 16, effectively adsorbing the upper material's surface and removing dust and debris from the material, thereby improving heat sealing quality. When the feeding conveyor 8 delivers the upper material to the vicinity of the feed frame 20, i.e., its initial operating position, the second cylinder 19 activates, pushing the feed frame 20 downward, placing the upper material within it. At this point, the third cylinder 22 remains retracted, and the pusher plate 21 does not push. The transmission chain 17 then pushes the upper material through the feed frame 20 to a predetermined position below the mold 5, i.e., its predetermined operating position. The upper electrode plate 4 then slides and descends longitudinally, carrying the mold 5, under the control of the machine body 3, until the mold 5 is in close contact with the lower electrode plate 6, thus performing the high-frequency heat sealing process on the upper material. The frequency energy is transferred to the material through the upper and lower electrode plates 6, causing the upper material to melt and bond at specific locations, forming a strong connection. At the same time, the material shifter 20 is moved to the initial working position via the transmission chain 17. After the high-frequency heat-sealing treatment of the upper material is completed, the upper electrode plate 4 rises back to its original position to cool the upper material and ensure that the heat-sealed parts are fully solidified. The material shifter 20 is moved to the predetermined working position via the transmission chain 17, and then the third cylinder 22 is activated, pushing the push plate 21 to move horizontally, pushing the upper material onto the unloading conveyor belt 10. The unloading conveyor belt 10 is activated, and the processed upper material is removed from the lower electrode plate 6 and sent out of the dust cover 1 through the discharge port 12.
