Description

Technical Field

[0001] This utility model relates to the field of supercritical foaming technology, and in particular to a supercritical foaming device for shoe soles with uniform heating. Background Technology

[0002] An existing supercritical foaming device for shoe soles, with publication number CN 220763310 U, involves connecting an external power source to a motor during the supercritical foaming process of the blank on the connecting seat. The motor starts working, driving a spiral blade to rotate. This spiral blade extracts the high temperature generated at the lower end of the outer shell, which is then transported through a conveying pipe into a guide plate for further temperature neutralization. The heated air is discharged through the outlet and continues to move downwards after contacting the blank, achieving repeated movement and ensuring uniform temperature of the outer shell, thus avoiding uneven surface conditions during supercritical foaming. However, the above device, which uses rotating spiral blades to circulate internal air for temperature neutralization, does not achieve ideal results and therefore urgently needs improvement. Utility Model Content

[0003] The purpose of this invention is to provide a supercritical foaming device for shoe soles that provides uniform heating in order to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A supercritical foaming device for uniformly heated shoe soles includes a foaming equipment body and a loading plate. A partition is horizontally fixed inside the housing of the foaming equipment body. Electric heating plates are installed on the upper and lower inner walls of the upper cavity of the partition. The device also includes an adjustment mechanism installed inside the housing for intermittently changing the distance between the loading plate and the electric heating plates during rotation. The adjustment mechanism includes a lifting assembly, a rotating assembly and a power assembly connected to the lifting assembly. The lifting assembly includes a vertically arranged drive shaft located below the partition. A rotating cylinder is fixedly installed on the drive shaft. A U-shaped groove is formed on the outer wall of the rotating cylinder. A transmission shaft is vertically arranged on one side of the drive shaft. A prismatic column is provided at the upper end of the transmission shaft. A lifting cylinder is sleeved on the outer diameter of the prismatic column. Two flange platforms are provided at the lower position on the outer diameter of the lifting cylinder. A sleeve is sleeved between the flange platforms. A sliding pin that mates with the U-shaped groove is fixed on the outer wall of the sleeve. A support plate is fixed at the upper end of the partition through which the lifting cylinder passes. The loading plate is installed on the support plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] By setting an adjustment mechanism within the foaming equipment, the power component of the adjustment mechanism drives the drive shaft and rotating cylinder of the lifting component to rotate. The loop groove on the rotating cylinder cooperates with the sliding pin on the sleeve, pushing the sleeve to move up and down as a whole, causing the support plate at the upper end of the lifting cylinder to move up and down synchronously.

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] like Figures 1-4 As shown, a supercritical foaming device for uniformly heated shoe soles includes a foaming equipment body 1 and a loading plate 3. A partition 11 is horizontally fixed inside the box of the foaming equipment body 1. Electric heating plates 12 are installed on the upper and lower inner walls of the upper cavity of the partition 11. The device also includes an adjustment mechanism installed inside the box for intermittently changing the distance between the loading plate 3 and the electric heating plate 12 when rotating.

[0024] In this embodiment: the adjustment mechanism includes a lifting assembly, on which a rotating assembly and a power assembly are connected. The lifting assembly includes a vertically arranged drive shaft 21, which is located below the partition 11. A rotating cylinder 22 is fixedly installed on the drive shaft 21. A loop groove 23 is formed on the outer wall of the rotating cylinder 22. A transmission shaft 24 is vertically arranged on one side of the drive shaft 21. A prismatic column 241 is provided at the upper end of the transmission shaft 24. A lifting cylinder 25 is sleeved on the outer diameter of the prismatic column 241. Two flange platforms 26 are provided at the lower position on the outer diameter of the lifting cylinder 25. A sleeve 28 is sleeved between the flange platforms 26. A sliding pin 29 that cooperates with the loop groove 23 is fixed on the outer wall of the sleeve 28. A support plate 27 is fixed at the upper end of the partition 11 through which the lifting cylinder 25 passes. 3. Installed on support plate 27; the upper and lower ends of the spiral groove 23 are both set to be horizontal, the sliding pin 29 is welded to the sleeve 28, and the sliding pin 29 is slidably connected to the spiral groove 23; the drive shaft 21 is rotatably connected to the partition plate 11 and the box body, and the transmission shaft 24 is rotatably connected to the box body; the sleeve 28 is rotatably connected to the lifting cylinder 25, and the lifting cylinder 25 is slidably connected to the prismatic column 241, so that during the rotation of the rotating cylinder 22 on the drive shaft 21, the spiral groove 23 on the rotating cylinder 22 cooperates with the sliding pin 29 on the sleeve 28 to push the sleeve 28 to move up and down as a whole, so that the support plate 27 at the upper end of the lifting cylinder 25 moves up and down synchronously, thereby making the loading plate 3 rotate while the upper and lower electric heating plates 12 are raised and lowered, improving the heating uniformity of the foam material in the loading plate 3.

[0025] The rotating assembly includes a drive gear 210 fixed on the drive shaft 21 and a secondary drive gear 211 fixedly mounted on the transmission shaft 24. The drive gear 210 and the secondary drive gear 211 mesh and rotate. When the drive shaft 21 rotates, the drive gear 210 on the drive shaft 21 meshes and rotates with the secondary drive gear 211 on the transmission shaft 24, driving the transmission shaft 24 and the prismatic column 241 to rotate, and driving the lifting cylinder 25 to rotate.

[0026] The power assembly includes a worm gear 213 rotatably mounted on the bottom of the housing, a worm wheel 212 meshing with the worm gear 213 fixedly mounted on the drive shaft 21, and an electric motor 214 connected to one end of the worm gear 213.

[0027] The working principle and usage process of this utility model are as follows: The foaming material is placed on the loading plate 3, the electric heating plate 12 is turned on, and the motor 214 drives the worm 213 to rotate. The worm 213 meshes with the worm wheel 212, which drives the drive shaft 21 and the rotating cylinder 22 to rotate. During the rotation of the rotating cylinder 22, it cooperates with the sliding pin 29 on the sleeve 28, pushing the sleeve 28 to move up and down as a whole, so that the lifting cylinder 25 moves up and down synchronously. At the same time, the drive gear 210 on the drive shaft 21 meshes with the auxiliary gear 211 on the transmission shaft 24, which drives the transmission shaft 24 and the prismatic column 241 to rotate, so that the prismatic column 241 drives the lifting cylinder 25 to rotate. In turn, the support plate 27 at the upper end of the lifting cylinder 25 drives the loading plate 3 to rotate while moving up and down between the upper and lower electric heating plates 12, thereby improving the heating uniformity of the foaming material in the loading plate 3.
