Description

Technical Field

[0001] This utility model relates to the field of shoe material processing technology, and in particular to a tunnel-feed shoe sole mold. Background Technology

[0002] In the processing of shoe soles, tunnel ovens may be used to bake the glued soles (composed of several layers of materials). For example, Chinese patent 02259407.8 discloses a tunnel-type shoe component oven with an exposed heating unit, through which a conveying unit transports shoe components for glue drying. This shoe component oven includes a body defining at least one channel, at least one pressure box unit disposed above the channel, at least one track mounted on the bottom of the pressure box unit, at least one removable heating unit inserted into the track, and multiple fan units that generate circulating airflow between the channel and the pressure box unit. In this way, the heat source generated by the heating unit can directly radiate heat to the shoe component, and the circulating airflow passing through the heater can generate thermal convection.

[0003] In addition, to further improve the bonding effect, some companies have adopted sole pressing devices to perform pressing before baking. For example, Chinese patent 202020313309.7 discloses a sole pressing device that can effectively prevent sole cracking. This device includes a fixed base, with symmetrically distributed fixed plates vertically arranged on the surface of the fixed base at its two side edges. A support plate is horizontally arranged between the two fixed plates at its top edge. A cylinder is located at the top of the support plate, and the end of the cylinder piston rod passes through the support plate and is welded to a movable plate. A first U-shaped plate is located in the middle of the bottom of the movable plate. A fixed block is located in the middle of the surface of the fixed base, and a second U-shaped plate is located on the surface of the fixed block. This sole pressing device, which can effectively prevent sole cracking, allows for the replacement of rubber pressure plates of different sizes according to the size of the sole using the first U-shaped plate, avoiding excessive pressure on any part of the sole and thus preventing cracking.

[0004] In the existing technology, the feeding of materials into the oven and pressing device is done manually, which is less efficient and poses a risk of burns and pressure injuries. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a tunnel-feed shoe sole mold.

[0006] The technical solution of this utility model is as follows:

[0007] A tunnel-feed shoe sole mold includes a feeding cylinder, a preparation platform, a pressing box, and an oven arranged sequentially from left to right on a workbench. The top surface of the preparation platform is flush with the bottom plate of the pressing box and the oven and a template is placed thereon. The pressing box and the oven are connected. A pressing cylinder is provided on the top of the pressing box. The push rod of the pressing cylinder extends into the pressing box and is fitted with a pressure plate. The oven is equipped with a heating mechanism.

[0008] In a preferred embodiment of this disclosure, the central axes of the feeding cylinder, the preparation platform, the pressing box, and the drying oven are aligned. Guardrails to prevent template slippage are provided on both sides of the preparation platform and on both sides of the bottom plates of the pressing box and the drying oven. The bottom plates of the preparation platform, the pressing box, and the drying oven have the same dimensions. This facilitates the template's smooth passage through the processing tunnel formed by the pressing box and the drying oven.

[0009] In a preferred embodiment of this disclosure, the extension length of the push rod of the feeding cylinder is equal to the length of the preparation table. Each extension of the feeding cylinder pushes a template placed on the preparation table into the pressing box.

[0010] In a preferred embodiment of this disclosure, the heating mechanism of the oven includes an air inlet pipe, a return air pipe, a circulation pipe, and a hot air fan. The air inlet pipe connects to the rear end of the oven, the return air pipe connects to the front end of the oven, and the air inlet pipe and return air pipe are connected through a circulation pipe, on which a hot air fan is installed. Its working principle is as follows: the hot air fan blows hot air into the oven through the air inlet pipe. Since the air inlet of the hot air fan is connected to the return air pipe, the hot air inside the oven flows towards the front end of the oven and eventually enters the return air pipe. The hot air is recycled, which reduces energy consumption.

[0011] In a preferred embodiment of this disclosure, curtains are hung at both the front and rear ends of the oven to further reduce heat loss.

[0012] In a preferred embodiment of this disclosure, the template includes a lower layer and an upper layer. The lower layer is made of self-lubricating plastic, and the upper layer is made of non-slip plastic. This is significant because the upper layer prevents the shoe material from sliding during template movement, while the lower layer facilitates template movement.

[0013] In a preferred embodiment of this disclosure, a hopper is provided at the end of the workbench for collecting templates and shoe materials.

[0014] In a preferred embodiment of this disclosure, the pressing chamber and the drying oven are made of tempered glass on both sides to facilitate observation of the internal conditions.

[0015] Beneficial effects of this utility model

[0016] According to this disclosure, a feeding cylinder is used to push the template, avoiding the need for people to put their hands into the pressing box or drying box, thus reducing the risk of injury; the template is used as a carrier to move the shoe material, with one template corresponding to one shoe material, to achieve rhythmic feeding.
