Description

Technical Field

[0001] This application relates to the field of shoemaking technology, specifically to an auxiliary baking device for shoemaking. Background Technology

[0002] In the shoe manufacturing process, baking is one of the key processes that affects shoe quality. Whether it is shaping the upper, vulcanizing the sole, or curing the glue, baking is necessary. Appropriate baking temperature, time, and uniformity can ensure that the various parts of the shoe are tightly bonded, achieving the ideal shape and performance, and improving the overall quality and durability of the shoe.

[0003] Placing the soles on a baking rack and baking them with a shoe dryer is a common baking method. However, during the bonding process between the soles and the uppers, the curing quality of the adhesive directly affects the bonding strength and durability of the shoes. When baking, the adhesive may cure unevenly, which can easily lead to localized weak bonding and subsequent separation. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and to propose an auxiliary baking device for shoemaking, so as to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides an auxiliary baking device for shoe making, including a baking oven, a shoe dryer installed inside the baking oven, a first fan installed at one end of the baking oven, a second fan installed at the end of the baking oven away from the first fan, a crossbeam fixedly connected to the inner side of the baking oven, a fixed cylinder fixedly installed on the crossbeam, a drive position horizontal swing rod movably passing through the inner side of the fixed cylinder through a spring mechanism, a connecting frame fixedly connected to one end of the drive position horizontal swing rod, a shoe sole clamping mechanism installed on the connecting frame, an eccentric drive mechanism installed on the baking oven, and a storage box installed next to the baking oven.

[0006] Preferably, the rebound mechanism includes a sleeve plate fixedly sleeved on the outer surface of the drive position horizontal swing rod, and the outer surface of the sleeve plate is slidably connected to the inner wall of the fixed cylinder. A spring is movably sleeved on the outer surface of the drive position horizontal swing rod. During the rotation of the eccentric wheel, the drive position horizontal swing rod can be pushed laterally (during which the spring in the rebound mechanism is gradually compressed, i.e., in an energy storage state). When the relatively pointed part gradually moves away from the drive position horizontal swing rod, the elastic reset action of the spring in the rebound mechanism is triggered, which can push the drive position horizontal swing rod back to its original position.

[0007] Preferably, the sole clamping mechanism includes several broken rubber plates detachably mounted on the outer surface of the frame. One end of the outer surface of the broken rubber plate is provided with a rubber tooth sleeve, and the other end of the outer surface of the broken rubber plate away from the rubber tooth sleeve is provided with a rubber tooth plate. The outer surface of the rubber tooth plate is engaged with the inner surface of the rubber tooth sleeve. The sole clamping mechanism can stably clamp multiple soles and change the clamping position of the soles.

[0008] Preferably, a connecting plate is fixedly connected to the bottom of the broken rubber sheet, and a clamp is provided at the bottom of the connecting plate.

[0009] Preferably, the eccentric drive mechanism includes a motor fixedly mounted on the outer surface of the baking oven. The output end of the motor is fixedly connected to a drive gear, and a chain is meshed with the outer surface of the drive gear. The eccentric drive mechanism can provide a lateral movement force to the drive position swing rod. In conjunction with the rebound mechanism, the drive position swing rod moves back and forth laterally. That is, the shoe sole, which is indirectly connected to the frame through the shoe sole clamping mechanism, can be baked by the shoe dryer during the back and forth "swinging" process.

[0010] Preferably, a rotating shaft is rotatably connected to the inner surface of the crossbeam, a transmission gear is fixedly connected to one end of the rotating shaft, and the outer surface of the transmission gear meshes with the inner side of the chain away from the drive gear. An eccentric wheel is fixedly connected to the end of the rotating shaft away from the transmission gear.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This auxiliary baking equipment for shoemaking uses an eccentric drive mechanism combined with a rebound mechanism to make the sole periodically "swing". Dynamic heat exchange effectively eliminates the heat blind spots of static baking, ensuring that the glue cures in a uniform temperature field. Combined with the through-duct design of two sets of fans, the forced airflow sweeps across all areas of the sole at high speed, accelerating solvent evaporation and removing odors. This linkage baking process makes the glue molecules cross-link more densely, and significantly improves the bonding strength and durability of the sole.

[0012] 2. This auxiliary baking equipment for shoe manufacturing features a detachable rubber plate combined with a rubber toothed sleeve and a rubber toothed plate meshing adjustment mechanism, which achieves dynamic optimization of the clamping posture. The spacing of the soles can be flexibly adjusted according to the size and type of the soles, ensuring uniform coverage of heat radiation and airflow organization. This spatial adaptability not only improves the compatibility of the equipment, but also avoids uneven baking caused by the soles being too dense or too sparse. Attached Figure Description

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] Please see Figure 1-6 An auxiliary baking device for shoe making includes a baking oven 1, a shoe dryer 2 inside the baking oven 1, a first fan 3 at one end of the baking oven 1, and a second fan 4 at the end of the baking oven 1 away from the first fan 3. The airflow direction of the first fan 3 and the second fan 4 is the same, forming a horizontal through-flow duct to force air circulation. The airflow evenly sweeps over the surface of the swinging shoe sole, accelerating the evaporation of solvent in the glue and expelling the odor generated during the baking process. At the same time, a crossbeam 5 is fixedly connected to the inner side of the baking oven 1, and a fixed cylinder 6 is fixedly installed on the crossbeam 5. A drive position horizontal swing rod 7 is movably inserted through the inner side of the fixed cylinder 6 through a rebound mechanism. A connecting frame 8 is fixedly connected to one end of the drive position horizontal swing rod 7, and a shoe sole clamping mechanism is provided on the connecting frame 8. An eccentric drive mechanism is provided on the baking oven 1, and a storage box 22 is provided next to the baking oven 1. The shoe soles after baking can be temporarily stored in the storage box 22 for subsequent unified processing.

[0017] Through the above technical solution, during the use of the equipment, multiple shoe soles are first stably clamped by the shoe sole clamping mechanism and suspended below the connecting frame 8 to be baked by the shoe dryer 2. During this process, the connecting frame 8 can be swung back and forth in the horizontal direction by the eccentric drive mechanism in conjunction with the rebound mechanism, so that the shoe soles are dried during the "swinging" process.

[0018] Specifically, the rebound mechanism includes a sleeve plate 14 fixedly sleeved on the outer surface of the drive position horizontal swing rod 7, and the outer surface of the sleeve plate 14 is slidably connected to the inner wall of the fixed cylinder 6, and a spring 15 is movably sleeved on the outer surface of the drive position horizontal swing rod 7.

[0019] Through the above technical solution, the two ends of the spring 15 are fixedly connected to the inner wall of the fixed cylinder 6 and the outer surface of the sleeve plate 14, respectively. When the protruding part of the eccentric wheel 21 contacts and laterally pushes the drive position swing rod 7, the sleeve plate 14 compresses the spring 15 to store energy. When the eccentric wheel 21 rotates until the protruding part disengages from the drive position swing rod 7, the spring 15 releases elastic potential energy and pushes the drive position swing rod 7 back to the initial position. Through the continuous rotation of the eccentric wheel 21 and the periodic energy storage and release of the spring 15, the drive position swing rod 7 realizes high-frequency reciprocating swing, driving the sole of the shoe to dynamically "swing" during the baking process.

[0020] Specifically, the shoe sole clamping mechanism includes several broken rubber plates 9 that are detachably installed on the outer surface of the connecting frame 8. One end of the outer surface of the broken rubber plate 9 is provided with a rubber tooth sleeve 10, and the other end of the outer surface of the broken rubber plate 9 away from the rubber tooth sleeve 10 is provided with a rubber tooth plate 11. The outer surface of the rubber tooth plate 11 is engaged with the inner surface of the rubber tooth sleeve 10.

[0021] Through the above technical solution, the broken rubber plate 9 can be clamped onto the surface of the connecting frame 8. The rubber toothed sleeve 10 and the rubber toothed plate 11 adopt an interlocking soft connection design. By adjusting the interlocking depth of the two, the broken rubber plate 9 can be tightly clamped onto the outer surface of the connecting frame 8 to ensure that it does not slip off during the swinging process.

[0022] Specifically, a connecting plate 12 is fixedly connected to the bottom of the broken rubber plate 9, and a clip 13 is provided at the bottom of the connecting plate 12.

[0023] Through the above technical solution, the clip 13 at the bottom of the connecting plate 12 is made of spring steel. It clamps the weak area of ​​the shoe sole edge (such as the shoe sole groove) through mechanical biting force, avoiding direct pressure on the functional surface of the shoe sole, while dispersing the clamping stress and preventing the shoe sole from deforming.

[0024] Specifically, the eccentric drive mechanism includes a motor 16 fixedly mounted on the outer surface of the baking oven 1, a drive gear 17 fixedly connected to the output end of the motor 16, and a chain 18 meshing with the outer surface of the drive gear 17.

[0025] With the above technical solution, after the motor 16 starts, it can drive the drive gear 17 to rotate, and under the transmission action of the chain 18, the linkage transmission gear 20 rotates synchronously, that is, the rotating shaft 19 and the eccentric wheel 21 also rotate synchronously.

[0026] Specifically, a rotating shaft 19 is rotatably connected to the inner surface of the crossbeam 5. A transmission gear 20 is fixedly connected to one end of the rotating shaft 19, and the outer surface of the transmission gear 20 meshes with the inner side of the chain 18 away from the drive gear 17. An eccentric wheel 21 is fixedly connected to the end of the rotating shaft 19 away from the transmission gear 20.

[0027] Through the above technical solution, during the process of the rotating shaft 19 being driven to rotate, it will drive the eccentric wheel 21 to rotate. During this period, the protruding part of the eccentric wheel 21 will gradually approach or move away from the end of the drive position horizontal lever 7.

[0028] Working principle: During use, multiple shoe soles are clamped by clips 13. Rubber toothed plates 11 are inserted into rubber toothed sleeves 10, tightening both ends of the broken rubber plate 9, thus stably holding it onto the surface of the connecting frame 8 (the position of the broken rubber plate 9 can be changed during this process to adjust the spacing between the shoe soles during baking). Then, the motor 16 is started, driving the drive gear 17 to rotate. Under the transmission of the chain 18, the transmission gear 20 and the rotating shaft 19 rotate synchronously, ultimately linking the eccentric wheel 21 to rotate. During this process, the protruding part of the eccentric wheel 21 periodically contacts and laterally pushes the drive lateral swing rod 7. As the drive lateral swing rod 7 is pushed, the spring 15 in the compression rebound mechanism is squeezed by the sleeve 14, gradually storing energy during the deformation process. During this process, the drive lateral swing rod 7 drives the shoe soles to move synchronously by pushing the connecting frame 8. When the protruding part disengages... When the drive position swing arm 7 is released, the spring 15 releases energy instantaneously under the elastic reset action, and then pushes the drive position swing arm 7 back to the initial position through the back of the sleeve plate 14, forming a high-frequency reciprocating swing. During this period, the connecting frame 8 moves synchronously, and each shoe sole performs a "swinging" action during the reciprocating swing. The shoe sole is driven by the eccentric drive mechanism to periodically "swing". The surfaces of the shoe sole alternately approach or move away from the heat source. This dynamic heat exchange makes the overall temperature of the shoe sole tend to be uniform, and the glue curing conditions are consistent, avoiding local over-baking or under-baking. At the same time, during the swinging process, the shoe sole is exposed to the high-speed airflow in turn by the heat radiation of the shoe dryer 2 and the through air duct formed by the first fan 3 and the second fan 4. This achieves dynamic and uniform heating, while the forced airflow accelerates the evaporation of solvent in the glue and removes the generated odor from the baking oven 1. Finally, the baked shoe sole is temporarily stored in the storage box 22 for subsequent unified processing.

[0029] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
