Description

Technical Field

[0001] The utility model relates to the technical field of leather shoe processing, in particular to a drying device for leather shoe production based on circular transmission. Background Art

[0002] Leather shoe production is the process of processing raw materials (such as leather, rubber, and fabric) into finished shoes. This process includes multiple steps: designing the shoe, preparing the materials, cutting, sewing, gluing, shaping, drying, inspecting, and finishing. Circular conveyor systems are widely used in leather shoe production to improve production efficiency and production line consistency. The drying step in leather shoe production is used to remove residual moisture from glue, ink, or other wet materials used in leather shoe production. This process helps ensure the shoe's stable shape, enhances its durability, and prevents deformation or mold.

[0003] Patent publication number CN 216493833 U discloses a circular conveyor-based drying device for leather shoes. A receiving housing is fixedly mounted on the front side of the connecting plate, and a motor is fixedly mounted inside the front of the housing. A transmission block is fixedly mounted on the output end of the motor. This circular conveyor-based drying device facilitates drying leather shoes at multiple angles during the drying process, extending the drying time at a specific angle, improving drying efficiency, and facilitating shoe fixation to prevent them from falling.

[0004] Although the above technology can perform multi-angle wind drying on leather shoes through the set arc-shaped air outlet, due to the slow wind drying speed, the shoes are still not dried after the arc-shaped transmission belt is completed. In particular, it is difficult to dry the inside thoroughly, and moisture will remain, which will affect subsequent production and quality. Therefore, it has certain limitations, so innovation is needed in this technology. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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 are within the scope of protection of the present invention.

[0022] In the production of leather shoes, drying equipment is needed. The utility model provides a drying device for leather shoe production based on circular transmission, which is specially used for drying leather shoes. Compared with the drying device for leather shoe production based on circular transmission with publication number CN 216493833 U, this device combines two drying methods, wind drying and heat source drying, which can better meet the drying effect in leather shoe production and improve the overall drying efficiency. Example

[0023] See also Figures 1-4 , the utility model provides a technical solution:

[0024] A drying device for leather shoe production based on circular transmission, comprising a circular conveyor belt 1, a transmission gear disc 2 at the top end of the circular conveyor belt 1, two limit pads 5 symmetrically provided on the transmission gear disc 2, and drying boxes 7 fixedly installed on the two corresponding parts of the top end of the circular conveyor belt 1, a plurality of drying lamps 12 fixedly installed on the inner wall of one drying box 7, and a fan 13 fixedly installed on the top of one side of the other drying box 7, the output end of the fan 13 passes through the corresponding drying box 7 and is fixedly connected to a connecting pipe 14. Through the two drying boxes 7, wind drying can be performed first and then heat source drying can be performed. The advantage of wind drying is that it can remove surface moisture and prevent moisture retention, thereby reducing thermal damage to the leather. The advantage of heat source drying is that it can accelerate deep drying, improve the overall drying speed, and make the leather shoes return to a dry state faster. The combination of the two drying methods can comprehensively dry the leather shoes and achieve a quick drying effect.

[0025] In this embodiment, an adjustment groove 3 is provided at the top of the transmission gear disc 2, and two sliders 4 are slidably connected to the inner wall of the adjustment groove 3. The tops of the two sliders 4 are fixedly connected to the middle of the bottom ends of adjacent limit pads 5, and the bottom ends of the two limit pads 5 are slidably connected to the top of the transmission gear disc 2. Both ends of the inner walls of the two adjustment grooves 3 are fixedly connected with tension springs 6, and one end of the two tension springs 6 is fixedly connected to the adjacent sliders 4. The tension springs 6 always remain in a stretched state, which can make the two limit pads 5 close to each other. Placing leather shoes between the two limit pads 5 can ensure that the two limit pads 5 always keep squeezing the leather shoes, thereby achieving the limitation of the leather shoes.

[0026] In this embodiment, racks 8 are fixedly installed on a part of the inner wall of the circular conveyor belt 1 located inside the drying box 7 on both sides. The two sets of racks 8 are meshed and connected with the outer wall of the transmission gear plate 2. The meshing design of the racks 8 and the transmission gear plate 2 allows the leather shoes to rotate along when entering the two drying boxes 7 for drying. Rotating the leather shoes can ensure that all parts are evenly exposed to wind and heat sources, avoiding uneven drying or residual moisture in certain parts. Through rotation, the air flow inside the shoes is improved, which helps to discharge moisture faster and improve the overall drying efficiency.

[0027] In this embodiment, baffles 9 are fixedly installed at both ends of the two drying boxes 7, and a through groove 10 is opened in the middle of the bottom end of the two baffles 9. The setting of the baffles 9 serves to seal the interior of the drying box 7 to ensure that heat will not be lost during the drying process.

[0028] In this embodiment, photoelectric sensors 11 are fixedly installed in the centers of the two baffles 9 on the back side, and a controller is installed on the top of one of the photoelectric sensors 11. A plurality of shunt pipes 15 are fixedly passed through the outer wall of the connecting pipe 14, and a plurality of nozzles 16 are fixedly passed through the bottom of the outer walls of the plurality of shunt pipes 15. One end of the plurality of shunt pipes 15 is fixedly connected to the inner wall of the adjacent drying box 7. The signal output ends of the two photoelectric sensors 11 are electrically connected to the signal input ends of the controller, and the signal output ends of the controller are electrically connected to the signal input ends of the plurality of drying lamps 12 and the fan 13 respectively. The set photoelectric sensor 11 can detect the passage or existence of an object by emitting and receiving light beams, thereby identifying the time when the leather shoes pass by. When the machine stops, when the time when the leather shoes stop entering and exiting the drying box 7 reaches the threshold set by the photoelectric sensor 11, the drying lamp 12 and the fan 13 stop running to avoid continuous movement affecting the life and increasing energy consumption.

[0029] Working principle: When in use, the processed leather shoes are placed between two limit pads 5, and the pushing force of the tension spring 6 drives the two limit pads 5 to squeeze and limit the leather shoes. At this time, the circular conveyor belt 1 runs to drive the transmission gear plate 2 to be transmitted on the circular conveyor belt 1. When passing through the first drying box 7, the fan 13 is operated to generate wind force, which is guided by the connecting pipe 14 and the diversion pipe 15 and evenly sprayed on the leather shoes through the nozzle 16, thereby playing a wind drying effect on the leather shoes, effectively removing moisture from the surface of the leather shoes, and then transported to the inside of another drying box 7 by the circular conveyor belt 1. The drying lamp 12 generates heat when it runs. The heat acts on the leather shoes to accelerate the thorough drying of the inside of the leather shoes, and when entering the two drying boxes 7, the outer walls of the transmission gear plate 2 are engaged and rotated with the adjacent racks 8, thereby achieving the effect of rotation during the drying process, which can accelerate the drying and realize effective drying of leather shoe production.
