Abstract
Description
Technical Field
[0001] This utility model relates to the field of bottom pressing machines, and in particular to a fully pneumatic energy-saving bottom pressing machine. Background Technology
[0002] Existing sole pressing machines use hydraulic cylinders to control two independent moving blocks on the left and right sides to press against the shoe upper, thereby pressing the shoe side. However, hydraulic rod control has problems such as hydraulic oil leakage, and the hydraulic system needs to maintain pressure continuously, which leads to the waste of electrical energy and increases electricity costs. In addition, the shoe side is often curved, while the moving blocks are often cubic and difficult to fit the curve of the shoe upper. Although soft materials can be used to cushion between the two, there will still be uneven force transmission. Utility Model Content
[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a fully pneumatic energy-saving bottom pressing machine with the advantages of energy saving, environmental protection and fast response speed.
[0004] This utility model provides a fully pneumatic energy-saving sole pressing machine, including a pressing assembly, a side pressing assembly, and a lifting control assembly. The pressing assembly is mounted above the side pressing assembly, and the lifting control assembly is located below the side pressing assembly and controls its vertical movement. The side pressing assembly includes a front and rear tightening assembly and a side tightening assembly, with the two side tightening assemblies respectively located on the left and right sides of the front and rear tightening assembly. The side tightening assembly includes several parallel moving units, each of which includes a compressed air bladder, a moving seat, and a telescopic cylinder. The compressed air bladder is located on one side of the moving seat and connected to an external gas inlet device, while the telescopic cylinder is located on the other side of the moving seat. When the moving seat contacts the shoe upper, air is inflated into the compressed air bladder to fill the gap between the moving seat and the shoe upper.
[0005] Furthermore, the movable base has an arc-shaped block on the side near the telescopic cylinder, and the telescopic cylinder has an arc-shaped groove on the side near the movable base into which the arc-shaped block can be inserted. The arc-shaped edge of the arc-shaped block and the arc-shaped edge of the arc-shaped groove protrude towards each other and are rotatably connected. A roller is provided in the arc-shaped groove.
[0006] Furthermore, the pressing assembly includes a first movable rod and a second movable rod arranged front to back. The second movable rod includes a connecting seat, a swing rod, and a telescopic rod. The swing rod is rotatably connected to the connecting seat, and the two ends of the telescopic rod are rotatably connected to the side walls of the swing rod and the connecting seat, respectively.
[0007] Furthermore, the front and rear tensioning assembly includes a servo motor and two opposing slides. The bottom of the two slides is provided with a rack structure symmetrically along the center, and a gear shaft that meshes with the rack structure is provided at the center point of the two slides. A transmission belt is provided between the gear shaft and the servo motor for transmission between the two.
[0008] Furthermore, the lifting control component is a lifting cylinder.
[0009] By adopting the above technical solution, the beneficial effects of this utility model are:
[0010] This invention uses a pneumatic cylinder instead of a hydraulic cylinder to control the movement of the side-tightening assembly, which not only achieves energy conservation and environmental protection in production but also improves the equipment's response speed. A compressed air bladder is installed on the moving seat to fill the contact gap between the rigid moving seat and the shoe upper, enabling force transmission. Arc-shaped blocks and arc-shaped grooves are added to the moving block and telescopic cylinder to increase the left-right swinging motion of the moving seat and improve the vertical contact force with the shoe upper. A side-pressing assembly that can be raised and lowered reduces the operator's work surface area. A servo motor controls the movement of the front and rear tightening assemblies, achieving efficient control and making adjustments more convenient.

[0041] 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. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.
[0042] Reference Figure 1-4 This utility model provides a fully pneumatic energy-saving bottom pressing machine, including a lower pressing component 1, a side pressing component 2, and a lifting control component 3.
[0043] The pressing component 1 is mounted above the side pressing component 2. The pressing component 1 can be a device used in existing sole pressing machines to fix shoe lasts from top to bottom. In this embodiment, it specifically includes a first movable rod 11 and a second movable rod 12 arranged front to back. The second movable rod 12 includes a connecting seat 12a, a swing rod 12b and a telescopic rod 12c. The swing rod 12b is rotatably connected to the connecting seat 12a. The two ends of the telescopic rod 12c are rotatably connected to the side wall of the swing rod 12b and the connecting seat 12a, respectively. The extension of the telescopic rod 12c causes the swing rod 12b to rotate around the connecting seat 12a.
[0044] The lifting control component 3 is located below the side pressing component 2 and controls its vertical movement. The lifting control component 3 can be a lifting cylinder.
[0045] The side pressing assembly 2 includes a front and rear tightening assembly 21 and a side tightening assembly 22, with the two side tightening assemblies 22 respectively located on the left and right sides of the front and rear tightening assembly 21.
[0046] The front and rear tensioning assembly 21 can be any existing shoe last front and rear fixing assembly. In this embodiment, the front and rear tensioning assembly 21 includes a servo motor 21a and two opposing slides 21b. The bottom of the two slides 21b is provided with a rack structure along the center symmetrically, and a gear shaft that meshes with the rack structure is provided at the center point of the two slides. A transmission belt is provided between the gear shaft and the servo motor 21a for transmission between the two.
[0047] The side-tightening assembly 22 includes several parallelly arranged moving units 22a. Each moving unit 22a includes a compressed air bladder 2a1, a moving base 2a2, and a telescopic cylinder 2a3. The compressed air bladder 2a1 is located on one side of the moving base 2a2 and is connected to an external gas inlet device. The telescopic cylinder 2a3 is located on the other side of the moving base 2a2. When the moving base 2a2 contacts the shoe upper, it inflates the compressed air bladder 2a1 to fill the gap between the moving base 2a2 and the shoe upper. To further increase the force exerted by the movable seat 2a2 on the shoe upper, an arc-shaped block 2a21 is provided on the side of the movable seat 2a2 near the telescopic cylinder 2a3. An arc-shaped groove 2a31 is provided on the side of the telescopic cylinder 2a3 near the movable seat 2a2, into which the arc-shaped block 2a21 can be inserted. The arc-shaped edges of the arc-shaped block 2a21 and the arc-shaped edges of the arc-shaped groove 2a31 protrude towards each other and are rotatably connected. A roller 2a32 is provided in the arc-shaped groove 2a31. When the shoe upper is tilted, the movable seat 2a2 will deflect around one end of the telescopic cylinder 2a3.
[0048] Working principle: When in use, the shoe last with the upper is placed in the side pressing component 2, and then the side pressing component 2 is raised so that the pressing component 1 presses the shoe last. Then, the single moving unit 22a and the slide 21b are activated to press the shoe upper from the side. When the moving seat 2a2 contacts the shoe upper, air is inflated into the compression airbag 2a1 to further increase the force on the shoe upper.
