The traditional shaping device generally designs the upper pressing roller as a spring-type structure, and the midsole can be squeezed into the feeding gap between the two pressing rollers through conveying. At this time, the upper pressing roller can press the two sides of the midsole together with the lower pressing roller under the action of the spring. However, if the thickness of the midsole varies significantly and the feeding gap does not meet the pressing requirements of the midsole, other problems may occur during the pressing process.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 5 As shown: a novel secondary shaping device for shoe midsoles, comprising a conveyor belt 1, a pressure roller assembly 2 forming a feeding gap located at the end of the conveyor belt 1, when the shoe midsole 3 pre-pressed and bonded by a pre-pressing device is conveyed through the conveyor belt 1 and squeezed into the feeding gap of the pressure roller assembly 2, the driven roller 202 of the pressure roller assembly 2 can elastically press its top surface and press it together with the active roller 201 to shape it.

[0023] Specifically, the active roller 201 and the driven roller 202 of the above-mentioned pressure roller assembly 2 are installed up and down in a fixed frame 203, and the mounting seat 213 is elastically installed in the fixed frame 203 through a spring 233. The driven roller 202 is combined with the mounting seat 213 in a plug-in manner, so that it can be elastically raised and lowered relative to the active roller 201; when the shoe midsole 3 is squeezed in from the feeding gap, the spring 233 used to connect the mounting seat 213 will be deformed, and its force will reverse to make the active roller 201 press the top surface of the shoe midsole 3.

[0024] Furthermore, the driven roller 202 includes a solid rod 212 inserted into a mounting seat 213, an eccentric rod 222 is rotatably sleeved on the outer side of the solid rod 212, and a hollow roller 232 is rotatably sleeved on the outer side of the eccentric rod 222 through a bearing; when the eccentric rod 222 rotates, the distance between the hollow roller 232 and the driven roller 202 will change, that is, the feed gap of the pressing roller assembly 2 under normal conditions can be appropriately increased or decreased through adjustment, and shoe midsoles 3 of different thicknesses can be squeezed in and pressed normally.

[0025] Specifically, the inner center of the eccentric rod 222 is concentric with the solid rod 212 , and the outer center is concentric with the hollow roller 232 .

[0026] Specifically, the eccentric rod 222 is detachably provided with a handle 242 at its end; Figure 4 , Figure 5 As shown, a key block is installed at the end of the eccentric rod 222 through a key slot, and a plurality of slots are provided in an annular shape on the handle 242. The key block of the eccentric rod 222 can be engaged in any slot of the handle 242, so that the eccentric rod 222 and the handle 242 are fixedly combined. When the handle 242 is rotated to rotate the eccentric rod 222, the hollow roller 232 will deviate up and down accordingly, thereby adjusting the feeding gap formed by the hollow roller 232 and the active roller 201 under normal conditions.

[0027] Specifically, when the handle 242 is combined with the eccentric rod 222, its outer side will also abut against the mounting seat 213 through a gasket with a damping effect. Since the gasket gives the handle 242 a damping feeling when rotating, it can prevent the eccentric rod 222 from rotating on its own, causing the hollow roller 232 to move without reason.

[0028] Furthermore, the above-mentioned forming frame 203 is equipped with a motor 223 for driving the active roller 201 to rotate, and the driven roller 202 is in a stationary state under normal circumstances. When the midsole 3 is squeezed into the feeding gap, the driven roller 202 can rotate under the action of the active roller 201 and the midsole 3, thereby pressing the midsole 3.

[0029] Furthermore, the ends of the solid rod 212 and the shaping frame 201 are both provided with hanging bolts 243 , and both ends of the spring 233 are hung on the hanging bolts 243 .

[0030] Furthermore, the hollow roller 232 of the driven roller 202 and the active roller 201 are both provided with elastic and anti-skid rubber sleeves on their outer surfaces, and the rubber sleeves can be used to improve the pressing effect of the pressing roller assembly 2 on the shoe midsole 3.

[0031] The working mode of this design is roughly the same as the existing technology and will not be described in detail in this article; when in use, if the thickness of the shoe midsole changes significantly, the handle can be manually turned to change the height of the driven roller so that the feed gap and the shoe midsole are adapted to each other.

[0032] As described in the background technology, the feed gap of the traditional shaping device can be changed dynamically according to the thickness of the shoe midsole; specifically, after the shoe midsole is transported and squeezed into the feed gap, the driven roller will press the shoe midsole firmly together with the active roller due to the restoring effect of the spring. However, this type of structure has certain usage prerequisites, that is, the shoe midsole to be pressed cannot have a significant difference in thickness from the feed gap of the shaping device; in simple terms, if the thickness of the shoe midsole is significantly smaller than the feed gap, the pressing effect of the shoe midsole is not ideal, conversely, if the thickness of the shoe midsole is significantly larger than the feed gap, the shoe midsole will be directly stuck at the front end of the pressing roller assembly. Based on the existence of the above-mentioned problems, this design provides the active roller with the ability to adjust itself by setting an eccentric structure in the active roller. The operator can appropriately adjust the feed gap according to the pressing condition of the shoe midsole, thereby avoiding the occurrence of the above-mentioned problems.

[0033] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
