Description

Technical Field

[0001] This invention relates to the field of shoe processing technology, and in particular to a shoe forefoot shaping mechanism. Background Technology

[0002] The shoe consists of a sole and an upper. The upper is further divided into a forefoot and a heel counter. Both the forefoot and heel counters are multi-layered, and the uppers are bonded together with adhesive. During the shaping process, hot and cold pressing equipment is used to shape and extrude the bonded uppers. Generally, a drive unit moves the base to the loading area. Then, a telescopic mechanism on the base raises the pressure bars between the pressure plates. The worker places the upper on the base, and then the telescopic mechanism lowers the pressure bars (which can also be plate-shaped), forming a pressure bar pressing a metal plate. The metal plate presses down on the upper, and the upper contacts the base. Then, a moving mechanism moves the base to the position of the lower pressing mechanism. The lower pressing mechanism, which is another lifting mechanism, lowers the lower pressure plate and presses down the pressure bars, so that the metal plate and the base can form a large clamping force, thereby making the bonding and shaping of the upper layers more secure.

[0003] In the process of implementing this solution, the inventors discovered the following problems in the existing technology that have not been adequately addressed: both ends of the pressure rod are fixed with side pressure plates, which are then connected to the telescopic mechanism. The pressure rod and the side pressure plates are integrated. Due to the large force exerted by the lifting mechanism to push the lower pressure plate down on the pressure rod, the pressure rod will deform after long-term operation. The deformed pressure plate will have a protruding part at the bottom, resulting in uneven force when pressing down on the iron plate, which in turn affects subsequent processing. Furthermore, since it is integrated, replacement requires replacing the entire unit, which is costly and cumbersome. Summary of the Invention

[0004] The main objective of this invention is to provide a shoe forefoot shaping mechanism that can effectively solve the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A shoe forefoot shaping mechanism includes a pressure base. Hydraulic rods are provided at both ends of the top of the pressure base. An L-shaped traction plate is fixed to the output end of each hydraulic rod. L-shaped pressure rods are provided at both ends of the L-shaped traction plates on their closest sides. Pressure plates are provided at both the front and rear ends of the L-shaped traction plates. A connecting plate is fixed to the bottom of each L-shaped pressure rod. A screw rod is welded to both ends of the pressure plate at the connecting plate position. A nut is threaded onto the outer wall of each screw rod. A transverse groove is chiseled into the side wall of each L-shaped traction plate. A second screw rod is inserted into both ends of the transverse groove. A nut is threaded onto the outer wall of the end of the second screw rod that is away from the pressure plate and passes through the transverse groove.

[0007] Preferably, the screw is connected through a connecting plate that is matched in position, and the bottom of the connecting plate is in contact with the top of the pressure plate.

[0008] Preferably, the nuts are located at the end of the connecting plate away from the pressure plate, and the bottom of the nuts is in contact with the top of the connecting plate.

[0009] Preferably, the end of the second screw away from the second nut is fixedly connected to the top end of the L-shaped pressure rod.

[0010] Preferably, the pressure-bearing base has sliding columns fixed at both ends of the L-shaped traction plate away from the pressure plate. The sliding columns are respectively connected to the two ends of the L-shaped traction plate away from the pressure plate, and the L-shaped traction plate is slidably connected to the sliding columns. Each sliding column is fitted with a return spring on the outer wall of the bottom end of the L-shaped traction plate. The top of the return spring is fixedly connected to the inner top of the L-shaped traction plate, and the bottom of the return spring is fixedly connected to the top of the pressure-bearing base.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. When the pressure plate is damaged due to deformation after being subjected to pressure for a long time, remove the nut from the screw at the top of the connecting plate. The nut can then be removed from the connecting plate by moving downwards, allowing the pressure plate to be separated from the L-shaped pressure rod. This makes it easy to replace the deformed and damaged pressure plate. The operation is simple and convenient, and the separable L-shaped pressure rod and pressure plate can save on replacement costs.

[0013] 2. Since men's, women's, and children's shoe upper sizes are different, the size of the metal plates is also different. The distance between the two pressure plates must also be adjusted according to the specific size of the metal plate. By removing the second nut, the second screw at one end of the L-shaped pressure rod can move laterally in the transverse groove, thereby changing the distance between the two pressure plates. This allows for the adjustment of the metal plate size to match the new size. The operation is simple and convenient. At the same time, when the L-shaped pressure rod is deformed or damaged for various reasons, the second screw can be pulled out from the transverse groove with the connecting plate separated from the pressure plate to disassemble the L-shaped pressure rod, thus facilitating its replacement.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4 As shown, a shoe upper shaping mechanism includes a pressure base 1. Hydraulic rods 2 are provided at both ends of the top of the pressure base 1. An L-shaped traction plate 3 is fixed to the output end of each hydraulic rod 2. L-shaped pressure rods 4 are provided at both ends of the L-shaped traction plates 3 on their respective sides. Pressure plates 5 are provided at both the front and rear ends between the L-shaped traction plates 3. A connecting plate 7 is fixed to the bottom of each L-shaped pressure rod 4. Screws 6 are welded to both ends of the pressure plate 5 at the position of the connecting plate 7. Nuts 8 are threaded onto the outer walls of the screws 6. Transverse grooves 9 are chiseled into the side walls of the L-shaped traction plates 3. Screws 10 are inserted into both ends of the transverse grooves 9. Nuts 11 are threaded onto the outer wall of the end of the screw 10 that is away from the pressure plate 5 and passes through the transverse groove 9.

[0021] Specifically, screw 6 is connected to connecting plate 7 with matching position, and the bottom of connecting plate 7 is in contact with the top of pressure plate 5. Nut 8 is located at the end of connecting plate 7 away from pressure plate 5, and the bottom of nut 8 is in contact with the top of connecting plate 7, so that connecting plate 7 and pressure plate 5 can be easily disassembled and replaced.

[0022] Specifically, the end of the screw 10 away from the nut 11 is fixedly connected to the top end of the L-shaped pressure rod 4, so that the L-shaped pressure rod 4 can change its position and limit its position after changing its position by using the screw 10 and the nut 11 in conjunction with the transverse groove 9.

[0023] Specifically, each of the outer walls of the hydraulic rod 2 is fixed with a fixing bracket 14, which is fixed to the top of the pressure base 1 to facilitate the limiting and fixing of the hydraulic rod 2.

[0024] Specifically, the pressure base 1 has sliding columns 12 fixed at both ends of the L-shaped traction plate 3 away from the pressure plate 5. The sliding columns 12 are respectively connected to the two ends of the L-shaped traction plate 3 away from the pressure plate 5, and the L-shaped traction plate 3 is slidably connected to the sliding columns 12. The sliding columns 12 are each fitted with a return spring 13 on the outer wall of the bottom end of the L-shaped traction plate 3. The top of the return spring 13 is fixedly connected to the inner top of the L-shaped traction plate 3, and the bottom of the return spring 13 is fixedly connected to the top of the pressure base 1, so that the lifting and lowering of the L-shaped traction plate 3 is stable.

[0025] Working principle: When the pressure plate 5 is damaged due to deformation caused by long-term pressure, the nut 8 located at the top of the connecting plate 7 is removed from the screw 6. At this time, the nut 8 can be removed from the connecting plate 7 by moving downwards, thus allowing the pressure plate 5 to separate from the L-shaped pressure rod 4. This facilitates the replacement of the deformed and damaged pressure plate 5. The operation is simple and convenient. The separable L-shaped pressure rod 4 and pressure plate 5 can save on replacement costs. Since the shoe upper sizes of men, women, and children are different, the size of the iron plate is also different. The gap between the two pressure plates 5 The distance also needs to be adjusted according to the specific size of the iron plate. By removing the second nut 11, the second screw 10 at one end of the L-shaped pressure rod 4 can move laterally in the transverse groove 9, thereby changing the distance between the two pressure plates 5, and thus achieving the adjustment of the iron plate after the size is changed to fit the size. The operation is simple and convenient. At the same time, when the L-shaped pressure rod 4 is deformed and damaged for different reasons, with the connecting plate 7 separated from the pressure plate 5, the second screw 10 can be pulled out from the transverse groove 9 to achieve the effect of disassembling the L-shaped pressure rod 4, which also facilitates the replacement of the L-shaped pressure rod 4.
