Description

Technical Field

[0001] This utility model relates to the field of rubber shoe production, specifically to a rubber shoe sole demolding auxiliary device. Background Technology

[0002] Rubber soles are widely used in the production of various footwear products due to their excellent elasticity, wear resistance, and slip resistance. In the molding process of rubber soles, rubber raw materials are placed in a baking mold, heated to melt, and vulcanized. After the sole cools to a certain temperature, it needs to be demolded from the mold.

[0003] Early demolding relied entirely on manual labor. Workers used hooks, crowbars, and other tools to directly insert into the high-temperature mold, prying and pulling to separate the sole from the mold. When the rubber sole is freshly molded, it is relatively soft, and forceful prying or pulling easily leads to edge tearing, surface scratches, and a high scrap rate, as well as the risk of hand burns. With the development of production technology, an auxiliary demolding device was designed into the production line. Its core improvement is the use of a vacuum pump to create suction cups that adsorb the sole, thus reducing damage caused by hard contact and lowering the scrap rate and operational risks to some extent.

[0004] However, since most existing suction cups have a fixed layout (such as an "I-shaped suction cup area"), they can only cover a specific area of ​​the sole, making them extremely unsuitable for various sole styles. For example, for pointed-toe shoes, with their narrow and sharp front end and wide rear end, suction cups need to be arranged in a "sparse in front and dense in back" pattern to effectively cover the suction area. Small suction cups are used at the front to fit the narrow space, while large suction cups are used at the rear to enhance load-bearing capacity. For thick-soled boots, with their raised edges and possibly anti-slip patterns in the middle, suction cups need to be distributed along the edges to avoid the patterned areas, and the suction cups need to have a certain degree of flexibility to conform to the edge curvature.

[0005] However, the existing suction cup layout cannot be flexibly adjusted according to the shape of the shoe sole, nor can it integrate multiple layout methods, which seriously affects production efficiency and cannot meet the production needs of modern rubber shoe soles for multiple varieties, small batches, and multiple products. Utility Model Content

[0006] The present invention aims to provide a rubber shoe sole demolding auxiliary device to solve the problem that the suction cup layout in the prior art cannot integrate multiple layout methods.

[0007] A rubber shoe sole demolding aid includes a frame, a drive mechanism, a support component, an adsorption component, and a negative pressure supply component. The drive mechanism is mounted on the frame, and the support component is connected to the drive mechanism and can perform lifting and rotating actions under its drive. The adsorption component includes at least two sets of adsorption units, each adsorption unit being distributed circumferentially along the support component, and the configuration of each set of adsorption units is suitable for different types of rubber shoe soles. The negative pressure supply component is connected to the adsorption units to provide the negative pressure required for adsorption.

[0008] The working principle and beneficial effects of this utility model: The drive mechanism moves the carrier component to move it up and down to approach or move it away from the shoe sole inside the mold, and then rotates to switch between different layouts of adsorption units. Depending on the type of shoe sole, the carrier component is rotated to align the appropriate adsorption unit with the shoe sole, and then negative pressure is provided by the negative pressure supply component to achieve adsorption and demolding.

[0009] This application solves the problem that traditional suction cup layouts cannot be flexibly adjusted according to the shape of the shoe sole, nor can they integrate multiple layout methods, thus meeting the production needs of modern rubber shoe soles for multiple varieties, small batches, and multiple products.

[0010] In the optimized configuration, the drive mechanism includes a lifting drive component and a rotating drive component; the lifting drive component is vertically mounted on the frame, and its output end is connected to the rotating drive component to drive it to lift; the output end of the rotating drive component is connected to the load-bearing assembly to drive the load-bearing assembly to rotate around its own axis.

[0011] In the optimized configuration, the lifting drive component is a cylinder, and the rotation drive component is a servo motor.

[0012] The cylinder provides vertical power to drive the servo motor and the supporting components to descend as a whole, so that the adsorption unit contacts the sole of the shoe. After adsorption is completed, the lifting drive component drives the whole to rise to achieve demolding. The servo motor provides circumferential power to drive the supporting components to rotate to the position of the target adsorption unit, so as to achieve rapid switching between different layouts.

[0013] Furthermore, the servo motor achieves self-locking of the output shaft through its built-in electromagnetic brake, ensuring that the load-bearing component remains stationary after switching the adsorption unit.

[0014] The optimized negative pressure supply assembly includes a vacuum generator, a negative pressure pipeline, and a solenoid valve group; the vacuum generator is connected to each adsorption unit through the negative pressure pipeline, and the solenoid valve group includes solenoid valves corresponding to each adsorption unit group, used to independently control the negative pressure on / off of each adsorption unit group.

[0015] The negative pressure generated by the vacuum generator is delivered to each adsorption unit through the negative pressure pipeline; when a certain group of adsorption units is working, the corresponding solenoid valve opens, and the negative pressure only acts on the suction cups of that group, while the solenoid valves of other groups are closed. Optimized, the adsorption unit comprises three groups, each including a support plate and multiple suction cups fixed to the support plate; one group of adsorption units is adapted to the soles of pointed-toe shoes, with its suction cups distributed sparsely at the front and densely at the back; another group of adsorption units is adapted to the soles of platform boots, with its suction cups distributed along the edge of the supporting component; and a third group of adsorption units is adapted to the soles of children's shoes, with its suction cups distributed in an I-shape. The three groups of adsorption units are adapted to pointed-toe shoes, platform boots, and children's shoes respectively, and their layout matches the shape of the shoe soles.

[0016] In an optimized configuration, the supporting component is a disk. Attached Figure Description

[0018] The reference numerals in the accompanying drawings include: shoe sole 1, suction cup 2, negative pressure pipeline 3, vacuum generator 4, solenoid valve 5, piston rod 6, cylinder 7, frame 8, disc 9, servo motor 10, and support plate 11. Detailed Implementation

[0019] The following detailed description illustrates the specific implementation method: Example: A rubber shoe sole demolding auxiliary device includes a frame 8, a drive mechanism, a disc 9, an adsorption unit, and a negative pressure supply component.

[0020] Rack 8 provides stable support as the mounting base, such as Figure 5 As shown, the drive mechanism includes a cylinder 7 and a servo motor 10. The cylinder 7 is fixedly mounted on the frame 8. The piston rod 6 of the cylinder 7 is fixedly connected to the servo motor 10 to drive its lifting and lowering. The output end of the servo motor 10 is fixedly sleeved on the disc 9.

[0021] like Figure 1 As shown, two sets of adsorption units are distributed along the circumference of the disk 9. Each adsorption unit includes a support plate 11 fixed to the disk 9 and multiple suction cups 2 fixed on the support plate 11; the adsorption units at the top are distributed as follows. Figure 2 As shown, the adsorption units are distributed in a sparse-to-dense pattern at the front and dense-to-dense pattern at the back, suitable for pointed-toe shoe soles. The distribution pattern of the adsorption units on the bottom is as follows: Figure 3 As shown, thick-soled boot soles are distributed along the edge of the support plate 11.

[0022] like Figure 4 As shown, the negative pressure supply assembly includes a vacuum generator 4, two sets of negative pressure pipelines 3, and matching solenoid valves 5. The vacuum generator 4 is fixed on the disc 9, and the negative pressure pipelines 3 are rigid pipes fixed to the disc 9 with clips. The negative pressure generated by the vacuum generator 4 is delivered to each adsorption unit through the negative pressure pipelines 3. When a certain adsorption unit is working, for example, when the lower adsorption unit is working, the corresponding solenoid valve 5 is opened, and the solenoid valve 5 corresponding to the upper adsorption unit is closed, so the negative pressure only acts on the lower suction cup 2. Initially, the disc 9 is in a high position. After the shoe sole 1 to be demolded is transferred to the work station along with the mold, the servo motor 10 drives the disc 9 to rotate, so that the matching suction unit is aligned with the shoe sole 1. After it is in place, the self-locking function of the servo motor 10 (i.e., the electromagnetic brake self-locks the output shaft of the servo motor 10) keeps the disc 9 stationary. The cylinder 7 drives the whole thing to descend. After the suction cup 2 contacts the shoe sole 1, the corresponding solenoid valve 5 opens, and the negative pressure causes the suction cup 2 to adhere to the shoe sole 1. After confirming that it is firmly in place, the cylinder 7 drives it to rise to achieve demolding. After rising to the designated position, the solenoid valve 5 closes, the suction cup 2 releases the shoe sole 1, and the device resets to wait for the next cycle.

[0023] This application solves the problem that the traditional suction cup 2 layout cannot be flexibly adjusted according to the shape of the sole 1, and cannot integrate multiple layout methods.
