Description

Technical Field

[0001] This utility model relates to the field of trimming machine technology, and more specifically, to a stabilizing bottom wheel for a shoe trimming machine. Background Technology

[0002] The stabilizing rollers of a shoe trimming machine are an important component of the machine's bottom. They are typically made of wear-resistant materials, such as high-quality rubber or engineering plastics. Their main function is to provide stable support during operation, ensuring smooth running and reducing wobbling and vibration.

[0003] A typical shoe trimming machine's bottom wheel usually consists of a single rotating wheel connected to the machine body. When the machine moves along the shoe edge to perform trimming operations, the bottom wheel contacts the working surface (such as a table or the supporting surface of the shoe sole), bearing part of the machine's weight and sliding or rolling stably. During the trimming process, debris, dust, and other particles from the shoe sole material may adhere to the rotating wheel. If not cleaned in time, these impurities will increase the resistance to the rotating wheel's rolling or sliding, thus affecting the stability of the bottom wheel and the quality of the shoe sole trimming.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figure 1-4In this utility model: a stabilizing bottom wheel for a shoe trimming machine includes a base 1, which is U-shaped. A rotating shaft 2 is fixedly connected to the inner side of the base 1. Two turntables 3 are mounted on the rotating shaft 2 and rotatably connected thereto. A ring-shaped mounting shaft 4 is rotatably connected between the two turntables 3. The two ends of the mounting shaft 4 pass through and extend to opposite sides of the two turntables 3. A nut 5 is threadedly connected to the right end of the mounting shaft 4. A support wheel 6 is mounted on the mounting shaft 4 and rotatably connected thereto. A mounting box 7 is fixedly connected to the left side of the base 1. A fan 8 is installed on the inner wall of the mounting box 7. An air inlet pipe 9 is connected to the right end of the mounting box 7. The rotating shaft 2 is hollow. The right end of the air inlet pipe 9 is connected to the rotating shaft 2. Two sets of ring-shaped air outlets 10 are opened on the rotating shaft 2.

[0025] In this invention, the base 1 is fixed to the body of the trimming machine, and multiple support wheels 6 are arranged in a ring on two turntables 3. The multiple support wheels 6 can form a moving wheel that contacts the working surface (such as the support surface of a table or shoe sole). This method can improve the flexibility of the bottom wheel, enhance adaptability, improve stability, and distribute wear on each support wheel 6 through pressure dispersion, thereby extending the life of the bottom wheel.

[0026] During use, the user turns on the fan 8, which sends air into the shaft 2 through the air inlet pipe 9. After the air enters the shaft 2, it is discharged from the air outlet 10. The air outlet 10 is distributed in a ring on the surface of the shaft 2, so that the air is evenly sprayed onto the surface of the support wheel 6. The air can blow off the dust and shoe sole material debris attached to the surface of the support wheel 6, thereby achieving the effect of cleaning the surface of the support wheel 6. After the dust on the surface of the support wheel 6 is cleaned, the resistance of the rolling or sliding of the wheel can be effectively reduced, thereby improving the stability of the bottom wheel.

[0027] Please see Figure 3 and 4 The bottom of the rotating shaft 2 is fixedly connected to a connecting rod 11, and the bottom end of the connecting rod 11 is fixedly connected to a cleaning brush 12, which is in the shape of a semi-circular arc.

[0028] In this utility model, the connecting rod 11 can be used to support the cleaning brush 12. During use, the turntable 3 rotates and multiple support wheels 6 will continuously slide over the bottom of the cleaning brush 12. The cleaning brush 12 can clean the support wheels 6, thereby improving the cleaning effect of the support wheels 6 and further improving the stability of the bottom wheel.

[0029] Please see Figure 1-4 The base 1 has a contact plate 13 installed on its inner side. The contact plate 13 is semi-circular in shape and its top is in contact with the support wheel 6.

[0030] In this invention, the contact plate 13 is configured such that when the support wheel 6 moves to the top of the contact plate 13, the support wheel 6 will roll along the top of the contact plate 13 as the turntable 3 rotates, and the support wheel 6 will rotate on the cleaning brush 12, thereby allowing the cleaning brush 12 to thoroughly clean the support wheel 6, improving the cleaning effect of the support wheel 6, and further improving the stability of the bottom wheel.

[0031] Please see Figure 3 and 4 The bottom of the contact plate 13 is equipped with a pressure sensor 14, and the bottom of the pressure sensor 14 is fixedly connected to the inner wall of the base 1.

[0032] In this invention, the pressure sensor 14 provides support for the contact plate 13. After the support wheel 6 contacts the contact plate 13, it applies a certain pressure. When the surface of the contact plate 13 is severely damaged, the pressure between the support wheel 6 and the contact plate 13 will decrease. By observing the change in pressure, the wear condition of the support wheel 6 can be determined, allowing the user to replace the support wheel 6 immediately and improving the practicality of the device. The user can remove the support wheel 6 from the mounting shaft 4 by rotating the nut 5, and then pull the mounting shaft 4 out of the turntable 3. At this time, the support wheel 6 can be replaced. The process is very convenient and quick, effectively improving the practicality of the device.

[0033] Please see Figure 1 and 3 The inner wall of the mounting box 7 is fixedly connected to a filter plate 15, which is located on the left side of the fan 8.

[0034] In this invention, the filter plate 15 can filter the air entering the rotating shaft 2, preventing dust from clogging the air outlet 10 and further improving the stability of the device.

[0035] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
