Description

Technical Field

[0001] This utility model relates to the field of rubber shaping technology, specifically a shaping device for processing rubber shoe soles. Background Technology

[0002] As a crucial component of footwear, the molding quality of rubber soles directly impacts the comfort, lifespan, and aesthetics of the entire shoe. In current rubber sole manufacturing processes, shaping typically relies on a combination of heat softening, pressure extrusion, and cooling curing steps to ensure the sole maintains its desired shape within the molding die.

[0003] Currently, most rubber shoe sole shaping devices on the market are static hot-press molding machines. These machines typically place the rubber insole into a predetermined position, then heat and press it using an upper or lower mold. After a set time, the product is manually or through an auxiliary mechanism transferred to a cooling station. These types of equipment have the following technical limitations:

[0004] Operational cycle breaks and inability to process continuously: In existing equipment, heating and shaping and cooling and curing are often separated into different devices or workstations, requiring manual handling or interruption of the process. This leads to thermal deformation, indentation or uneven cooling of insoles during the process flow, resulting in poor molding quality stability.

[0005] Lacking a synchronous linkage structure, the structure is complex and the maintenance cost is high: In traditional equipment, multiple pressurization units cannot operate synchronously. Each module is controlled by an independent drive mechanism, resulting in a complex transmission chain. This is not conducive to batch, multi-station, and high-efficiency synchronous shaping operations, and increases the failure rate and maintenance cost.

[0006] In view of this, this paper studies and improves upon the existing problems, and provides a shaping device for processing rubber shoe soles to solve the current problems. The aim of this technology is to solve the problems and improve its practical value. Utility Model Content

[0007] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0008] Therefore, the technical solution adopted by this utility model is as follows: a shaping device for processing rubber shoe soles, comprising: a transmission seat, several pressing components, several hot pressing plates and several cooling plates. The number of pressing components is several and they are arranged in a straight line along the inner side of the transmission seat. The hot pressing plates and cooling plates are alternately arranged on the surface of each pressing component. The pressing component includes a fixed plate, a transmission shaft, a rotating pin shaft and a pressing seat. The fixed plate is located on both sides of the pressing seat and fixed to the inner side of the transmission seat. The transmission shaft is rotatably installed on the inner side of the fixed plate. The rotating pin shaft is rotatably installed on the surface of the fixed plate, and an eccentric wheel located on the inner side of the pressing seat is fixedly sleeved on the surface of the rotating pin shaft. The surfaces of the transmission shaft and the rotating pin shaft are provided with mutually meshing transmission teeth.

[0009] This structure enables synchronous transmission of the pressing components and eccentric pressing action of the pressing seat, improving the uniformity of force and processing accuracy during the shaping process.

[0010] In one possible implementation, the two sides of the pressure seat slide against the inner side of the fixing plate, and the hot pressing plate and cooling plate are embedded in the bottom surface of the pressure seat.

[0011] This structure ensures full contact between the hot and cold components and the sole, facilitating the conduction of hot pressing or cooling effects and improving shaping efficiency and quality.

[0012] In one possible implementation, several pressing components are divided into multiple groups of two, and each group of pressing components is symmetrically arranged on the transmission seat. The surface of the transmission shaft is provided with a synchronous pulley, and each group of pressing components is synchronously connected through the synchronous pulley and a synchronous belt sleeved on the surface of the synchronous pulley.

[0013] This structure enables the coordinated operation of multiple pressing components, simultaneously heating and softening, extruding and deforming, and cooling and shaping the insole during the dynamic conveying process, ensuring overall synchronization and consistency in sole shaping.

[0014] In one possible implementation, the pivot pin is rotatably mounted on the surface of the fixed plate and passes through the pressure seat. The outer circumference of the eccentric wheel is offset from the axis of the pivot pin, and the outer circumference of the eccentric wheel is provided with a number of balls located inside the pressure seat.

[0015] This structure achieves the reciprocating motion of the pressure seat through the cooperation of eccentric wheels and ball bearings, and performs peristaltic transmission of the insole during the compression process on the insole surface.

[0016] In one possible implementation, the hot press plate includes a resistance heating element and a first press plate, with the resistance heating element embedded inside the first press plate.

[0017] This structure enables continuous and stable heating and shaping of the sole, ensuring the stability of the sole shape and the consistency of heat treatment.

[0018] In one possible implementation, the cooling plate includes a Peltier cooling plate and a second pressure plate, the second pressure plate being adhered to the cooling surface of the Peltier cooling plate.

[0019] This structure allows for rapid cooling and molding of the shoe sole, improving molding efficiency and preventing thermal deformation.

[0020] In one possible implementation, the input terminals of both the hot press plate and the cooling plate are electrically connected to a constant temperature control module for adjusting and controlling the temperature of the hot press plate and the cooling plate.

[0021] This structure enables precise temperature control, making the heat setting and cooling process more intelligent and efficient, and improving the overall stability and automation of the machine.

[0022] The beneficial effects achieved by this utility model are as follows:

[0023] 1. In this utility model, the meshing transmission structure between the transmission shaft and the pivot pin, and the eccentric wheel on the pivot pin driving the pressure seat to reciprocate eccentrically, not only realize the extrusion and shaping of rubber insoles, but also complete the creeping propulsion during dynamic conveying, so that the insoles are heated, deformed and cooled sequentially between the hot press plate and the cooling plate, which significantly improves the continuity and processing consistency of the sole shaping process.

[0024] 2. In this utility model, multiple pressing components are grouped together and linked by a synchronous wheel and a synchronous belt set on the surface of the transmission shaft to achieve synchronous driving and coordination of multiple pressing components; combined with the electric drive structure and constant temperature control module to accurately control the temperature of the hot pressing plate and the cooling plate, the automation level, process stability and batch production efficiency of the device are further improved.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0035] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0036] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a shaping device for processing rubber shoe soles.

[0037] Combination Figures 1-5 As shown, the present invention provides a shaping device for processing rubber shoe soles, including a transmission base 100, a plurality of pressing components 200, a plurality of hot pressing plates 300, and a plurality of cooling plates 400. The pressing components 200 are arranged in a straight line along the inner side of the transmission base 100, and the plurality of hot pressing plates 300 and cooling plates 400 are alternately arranged on the surface of each pressing component 200.

[0038] The pressing assembly 200 consists of a fixed plate 210, a drive shaft 220, a pivot pin 230, and a pressing base 240. The fixed plate 210 is located on both sides of the pressing base 240 and is fixedly installed inside the drive base 100. The drive shaft 220 is rotatably mounted inside the fixed plate 210, with one end connected to an electric drive structure (not shown) to provide rotational power. The pivot pin 230 is rotatably mounted on the outer surface of the fixed plate 210, and an eccentric wheel 231 is fixedly sleeved on its surface. The eccentric wheel 231 is located inside the pressing base 240 and drives the pressing base 240 to perform reciprocating eccentric motion. The surfaces of the drive shaft 220 and the pivot pin 230 are respectively provided with drive teeth 222, and synchronous power transmission is achieved through their meshing.

[0039] During use, the rubber insole is placed between adjacent pressing components 200 by manual or automatic feeding system. When the electric drive structure is activated, it drives the transmission shaft 220 to rotate, which in turn drives the rotating pin 230 to rotate through the transmission gear 222. This causes the eccentric wheel 231 on the rotating pin 230 to generate an eccentric rotation trajectory, thereby driving the pressing seat 240 to oscillate eccentrically up and down. The bottom of the pressing seat 240 is equipped with a hot pressing plate 300 and a cooling plate 400. Under the squeezing action of the pressing seat 240, the rubber insole is gradually pushed forward, and along the transmission path, it sequentially completes heating, softening, pressing deformation, and cooling shaping.

[0040] Specifically, the two sides of the pressure base 240 slide against the inner side of the fixing plate 210, allowing the pressure base 240 to move smoothly under the drive of the eccentric wheel 231. The hot pressing plate 300 and the cooling plate 400 are embedded in the bottom surface of the pressure base 240 to ensure that the heating and cooling surfaces are in close contact with the rubber insole, achieving good heat transfer effect.

[0041] like Figure 2 and Figure 3 As shown, multiple pressing components 200 are divided into multiple working groups, each group consisting of two pressing components 200 and symmetrically arranged on the transmission base 100. A synchronous pulley 221 is provided on the surface of the transmission shaft 220. Each group of pressing components 200 is connected to a synchronous belt fitted onto it via the synchronous pulley 221, achieving synchronous linkage between multiple groups of pressing components 200. This ensures process consistency and efficiency in each step while dynamically conveying the rubber insole.

[0042] like Figure 4 As shown, the pivot pin 230 passes through the pressure seat 240, and the eccentric wheel 231 fitted on its outer surface has an eccentric structure, with its center offset from the axis of the pivot pin 230. When the pivot pin 230 rotates, the eccentric wheel 231 pushes the balls in the pressure seat 240 to form a reciprocating eccentric thrust, causing the pressure seat 240 to produce a continuous squeezing motion, thereby pushing the insole to creep along the path and improving processing efficiency and pressing uniformity.

[0043] like Figure 5 As shown, the hot press plate 300 includes a resistance heating element and a first press plate. The resistance heating element is embedded in the inner side of the first press plate and provides a stable heat source to the first press plate after being energized, for heating and softening the insole. The cooling plate 400 includes a Peltier cooling plate and a second press plate. The second press plate is attached to the cooling surface of the Peltier cooling plate. When the Peltier cooling plate is working, the second press plate can quickly cool the surface of the insole to achieve cooling and shaping.

[0044] In addition, the input terminals of the hot press plate 300 and the cooling plate 400 are electrically connected to the constant temperature control module. The constant temperature control module can adjust the working temperature of the hot press plate 300 and the cooling plate 400 in real time according to the preset process temperature requirements, thereby ensuring that the heating and cooling operations during the insole shaping process are always in the optimal state, and improving the molding stability and consistency.

[0045] With the above-described specific structural configuration, the shaping device for rubber shoe sole processing described in this utility model can simultaneously complete heating, extrusion, and cooling operations during the dynamic conveying of rubber insoles, thereby achieving rapid, efficient, and automated shaping processing of rubber shoe soles.

[0046] The working principle and usage process of this utility model;

[0047] The rubber insoles are placed between the pressing components 200 by a manual or automatic feeding system. Several pressing components 200 are arranged in a straight line along the inner side of the transmission seat 100 and are precisely positioned through structural fit. The hot pressing plate 300 and the cooling plate 400 are alternately embedded in the bottom surface of the pressing base 240, so that the insoles are subjected to hot pressing and cooling in sequence on the conveying path.

[0048] Each pressing assembly 200 consists of a fixed plate 210, a drive shaft 220, a pivot pin 230, and a pressing base 240. The fixed plate 210 is located on both sides of the pressing base 240 and is fixedly installed inside the drive base 100. The drive shaft 220 is rotatably mounted inside the fixed plate 210, while the pivot pin 230 is rotatably mounted on the outer surface of the fixed plate 210. An eccentric wheel 231 is fixedly sleeved on the outer surface of the pivot pin 230, and the eccentric wheel 231 is located inside the pressing base 240. An electric drive structure is connected to the end of the drive shaft 220, and synchronous power transmission is achieved through the transmission between the drive shaft 220 and the pivot pin 230.

[0049] The rotation of the drive shaft 220 synchronously drives the rotating pin 230 and the eccentric wheel 231 to rotate. The outer circumference center of the eccentric wheel 231 is offset from the rotation axis of the rotating pin 230. When the rotating pin 230 rotates, it drives the eccentric wheel 231 to rotate around the eccentric circular trajectory, thereby driving the pressure seat 240 to reciprocate eccentrically.

[0050] Furthermore, when this reciprocating motion acts on the insole surface, it enables the insole to be continuously propelled locally along the shaping path, creating an effect similar to peristaltic transport. In this way, the system can simultaneously complete the entire process of heating and softening, extrusion deformation, and cooling and shaping of the insole while it is dynamically transporting it, greatly improving operational continuity and molding consistency.
