Description

Technical Field

[0001] This utility model relates to the technical field of shoe sole trimming devices, and in particular to a shoe sole trimming device for slipper production and processing. Background Technology

[0002] In the production and processing of slippers, sole trimming is a crucial post-processing step. Its main purpose is to remove excess material such as burrs and flakes generated during the molding process, thereby improving the product's appearance and wearing comfort. With the development of automated production technology, more and more sole trimming devices are being applied to the slipper manufacturing industry to replace traditional manual trimming methods, improving production efficiency and processing consistency.

[0003] Currently, most commercially available shoe sole trimming devices use a side-clamping method to position the slippers. This involves using pneumatic or electric clamps to grip the sole from both sides, maintaining stability during the trimming process. However, this clamping method has several limitations in practical applications. First, due to the diverse shapes and complex edge structures of slipper soles, especially when there is an irregular ring of waste material around the edge, traditional side-clamping structures are prone to interfering with the area to be trimmed, affecting the cutting path of the tool and the trimming accuracy. Second, during the trimming process, to avoid the clamping points, it is often necessary to adjust the clamping position multiple times or trim in sections, leading to reduced trimming efficiency, extended processing time, and impacting the overall production cycle. Furthermore, frequent adjustments to the clamping mechanism increase the complexity of equipment control and operational difficulty, hindering truly automated continuous production.

[0004] Therefore, there is an urgent need for an automatic and efficient sole trimming device for slipper production. Utility Model Content

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1: A sole trimming device for slipper production and processing, such as... Figure 2 , Figure 3 and Figure 4As shown, the machine includes a frame 1, mounting racks 2, conveyor belts 3, infrared detectors 301, a first electric slide rail 4, a second electric slide rail 5, a first motor 6, a second motor 7, a pulley assembly 71, and conical blades 8. The frame 1 has two mounting racks 2, each designed specifically for a single slipper, allowing for the simultaneous processing of a pair of slippers, significantly improving production efficiency. Each mounting rack 2 has two conveyor belts 3, responsible for smoothly transporting the slippers to the designated position. Each conveyor belt 3 has two anti-slip pads attached to it to ensure the slippers do not slip or shift during transport. An infrared detector 301 is located on the upper part of the mounting rack 2. This detector can scan the slipper outline in real time, identify the edge position, and confirm the center alignment, thus providing accurate data support for subsequent trimming paths. The mounting rack 2 has two mounting racks 2 on its front and rear sides. Each component is equipped with a first electric slide rail 4. The first electric slide rails 4 on the same mounting bracket 2 are slidably connected to a second electric slide rail 5. The dual-axis layout allows the trimming mechanism to move freely on the horizontal plane, covering a wider working area. A first motor 6 is slidably mounted on the second electric slide rail 5. A connecting block is connected to the bottom of the output shaft of the first motor 6. A second motor 7 is installed inside the connecting block. A pulley assembly 71 is rotatably mounted on the connecting block. The pulley assembly 71 includes two pulleys, an upper and a lower one, and a belt wound around them. The output shaft of the second motor 7 is connected to the pulley at the upper part of the pulley assembly 71. A conical blade 8 is mounted on the pulley at the lower part of the pulley assembly 71. Power is transmitted to the lower pulley through belt drive, thereby driving the conical blade 8 mounted on the lower pulley to rotate at high speed.

[0025] When the soles of slippers need to be trimmed, the operator places the slippers between two opposing conveyor belts 3 within the mounting frame 2. The conveyor belts 3 automatically transport the slippers to the central processing area. During the transport process, the infrared detector 301 scans the outline of the slippers in real time, identifies the edge position and centering status, and ensures the trimming path is accurate. After reaching the workstation, the control system starts the trimming program. The first electric slide rail 4 is adjusted laterally, and the second electric slide rail 5 is finely adjusted longitudinally to achieve multi-directional coverage. At the same time, the first motor 6 drives the connecting block to rotate, which drives the trimming component to adjust the angle so that the conical blade 8 fits the edge of the sole. After the adjustment is in place, the second motor 7 starts, which drives the conical blade 8 to rotate at high speed through the pulley group 71 to precisely cut and grind the edge of the slipper, completing the fully automatic trimming operation.

[0026] Example 2: Based on Example 1, such as Figure 1 , Figure 5 and Figure 6As shown, the mounting frame 2 also includes an electric push rod 9, a movable frame 10, a limiting block 101, a guide frame 11, an air pump 12, a collection frame 13, an air suction pipe 14, and guide wheels 15. Electric push rods 9 are installed on both sides of the mounting frame 2, and the movable frame 10 is connected to the electric push rod 9. The movable frame 10 is equipped with a limiting block 101, and a movable rubber fixing pad is provided on the limiting block 101. Depending on the specific shape and edge structure of the slipper, the operator can select a suitable rubber fixing pad for quick replacement to achieve the best clamping effect. Two collection frames 13 are installed inside the mounting frame 2, and the collection frames 13 are equipped with guide wheels 15. Air pumps 12 are installed at both the front and rear of the guide frame 11. The collection frame 13 is connected to the guide frame 11. Suction pipes 14 are installed at both the front and rear of the mounting frame 2. The suction pipes 14 are connected to the guide frame 11. The top of the suction pipe 14 has a unique funnel-shaped suction hole structure, which has a large adsorption area and good airflow guidance, and can effectively adsorb the surface of shoe soles of various shapes and materials. Guide wheels 15 are installed at both the front and rear ends of the limiting block 101. When the air pump 12 is started, a strong negative pressure environment is formed, which firmly fixes the bottom of the slipper, ensuring high precision and stability in the trimming process.

[0027] Before placing the slippers on conveyor belt 3 for trimming, their position needs to be automatically corrected and fixed. The operator places the slippers between the two conveyor belts 3, selects a suitable rubber fixing pad according to the shape of the sole, and installs it into the limiting block 101. The control system starts the electric push rods 9 on both sides, which drive the moving frame 10 and the limiting block 101 to move towards the center. The rubber fixing pad pushes the slippers to the center alignment and clamps them. Then, the air pump 12 starts, and the funnel-shaped suction hole at the top of the suction pipe 14 forms a negative pressure to adsorb the bottom of the slippers, ensuring that they remain stable during the trimming process. After the trimming is completed, the electric push rods 9 reset, releasing the clamping force. The trimming waste falls into the guide frame 11 under the action of gravity and is finally collected in the collection frame 13, keeping the working environment clean.
