[0002] At present, in the footwear product testing project, the process of preparing the sole test sample is cumbersome. In the existing process, the staff will peel off the insole with tools. Among them, the outsole with special patterns and very thick heels need to be manually cut and adjusted by the staff. Then the cut samples are cut into standard length and width, and then put on the grinding wheel grinder to grind the insole and outsole (the grinding process takes 30 minutes, and the staff needs to check the grinding status in the middle. After the insole is polished, the sample is reinstalled and the outsole is polished). Finally, it is polished to the appropriate thickness and surface flatness before testing.

[0003] However, this existing technology requires the full participation of workers in the entire process, and there are many problems. For example, there is a risk of injury during the cutting process, the grinding process will generate heat that affects the test performance of the sample, and the surface thickness after grinding will be uneven due to reasons such as the soft sample. The entire process from sample preparation to grinding takes about 40 minutes, which is inefficient.

[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] like Figure 1 and Figure 2 As shown, the present invention provides an operation method for adjusting the cutting thickness when cutting the sole material, comprising the following operation steps:

[0029] A shoe sole cutting device is provided. In specific implementation, the device may use, but is not limited to, a metal frame structure to ensure overall stability.

[0030] The annular knife belt in the sole cutting device is a key component. In specific implementation, the annular knife belt can be selected from but not limited to an annular knife belt made of high carbon steel, which has high hardness and good toughness and can meet the cutting requirements of sole materials. The annular knife belt has a total length of about 2 meters and is tensioned and fixed by two symmetrical pulleys on the left and right. In specific implementation, when installing the annular knife belt, a special tensioning tool can be used to adjust it to ensure uniform tension of the annular knife belt.

[0031] Among them, for the pulley, in the specific implementation, cast iron pulleys can be selected but not limited to, which have good wear resistance and stability. One pulley is a driving wheel, which can rotate at high speed to drive the annular knife belt to rotate. In the specific implementation, the driving method of the driving wheel can be selected but not limited to electric motor drive, and its speed can be adjusted according to actual needs, such as between 1000-5000 rpm.

[0032] There is a 0.5 meter wide distance between the two pulleys, and the annular knife belt is relatively horizontal with the sample feeding device. In specific implementation, the sample feeding device can be selected from but not limited to a linear guide type sample feeding device with a precise pushing function, which can accurately feed the sole sample into the cutting position.

[0033] The specific operation process is as follows:

[0034] First, the sole sample is fed into the device through the sample feeding device. In this embodiment, the sole sample can be selected from but not limited to soles of different types and materials such as leather shoe soles (such as cowhide soles, sheepskin soles, etc.), sports shoe soles (such as EVA soles, rubber soles, etc.).

[0035] Then measure the thickness of different positions of the sole sample. In specific implementation, the measuring tool can be selected but not limited to a laser thickness gauge or a mechanical contact thickness gauge. After confirming the maximum thickness, determine the peeling thickness and the lower wheel gap (the lower wheel gap is the thickness of the discarded sample) according to the thickness of the sample to be retained.

[0036] Next, the upper and lower pressing rollers in the sole cutting device are used to fix and compress the sole sample. In specific implementation, the upper and lower pressing rollers can be selected from but not limited to those made of aluminum alloy, and the surface thereof can be selected from but not limited to a design with a rubber anti-skid layer, so that the sole sample can be better fixed to prevent sliding. Then, the sole sample is cut by an annular blade, and the sample is cut into upper and lower parts according to the set peeling thickness and the gap between the lower wheels, wherein the upper part is the required sample, and the lower part is discarded.

[0037] During the cutting process, the cutting thickness can be slowly adjusted according to the actual situation of the sample after cutting, so as to gradually cut off the unevenness or uneven thickness of the surface. In specific implementation, the mechanism for adjusting the peeling thickness can be selected but not limited to controlling the spacing between the annular knife belt and the lower wheel through a screw fine-tuning device, and the adjustment accuracy can reach 0.1mm. And the front and back sides of the sample can be cut arbitrarily. In addition, the cutting process data of different samples can be recorded for reference to facilitate the use of newcomers later. In specific implementation, data recording can be selected but not limited to a microcontroller-based data acquisition system, which can store data in a large-capacity flash memory chip, such as peeling thickness, lower wheel gap, cutting time, sample number and other related data.

[0038] In addition, the step of recording cutting process data includes the following aspects:

[0039] 1. Cutting parameter recording

[0040] Tool parameters:

[0041] Record information such as the tool model, tool diameter, number of tool edges, tool material, etc. These parameters will affect cutting force, cutting temperature, cutting efficiency, etc.

[0042] Cutting speed: Record the tool rotation speed or feed speed during the cutting process. The cutting speed will directly affect the cutting force, cutting temperature and machining surface quality.

[0043] Feed rate: Record the feed rate of the tool per revolution or per stroke during the cutting process. The feed rate will affect the cutting force, cutting temperature and machining accuracy.

[0044] Cutting depth: records the depth of the tool into the workpiece during the cutting process. The cutting depth will affect the cutting force, cutting temperature and processing efficiency.

[0045] 2. Cutting force and cutting temperature records

[0046] Cutting force: The size and direction of the cutting force are measured by a force sensor installed on the tool or workpiece, and the changes in the cutting force are recorded. The size of the cutting force will affect the tool wear, processing accuracy and surface quality.

[0047] Cutting temperature: The cutting temperature is measured by installing a temperature sensor on the tool or workpiece, and the changes in cutting temperature are recorded. The cutting temperature will affect the tool wear, processing accuracy and surface quality.

[0048] 3. Machining accuracy and surface quality records

[0049] Processing accuracy: record the size accuracy, shape accuracy and position accuracy of the workpiece after processing. The level of processing accuracy will directly affect the performance and quality of the workpiece.

[0050] Surface quality: record the surface roughness, surface hardness, surface residual stress, etc. of the workpiece after processing. The quality of the surface will directly affect the performance and appearance quality of the workpiece.

[0051] 4. Cutting time and cutting path record

[0052] Cutting time: record the total time of the cutting process and the time of each cutting step. The length of cutting time will affect processing efficiency and production cost.

[0053] Cutting path: records the movement trajectory and path of the tool during the cutting process. The rationality of the cutting path will affect the processing accuracy and surface quality.

[0054] 5. Other data records

[0055] Workpiece material: record the material, hardness, toughness and other information of the workpiece. These parameters will affect the cutting force, cutting temperature and machining accuracy.

[0056] Cutting fluid: record the type, concentration, flow rate and other information of the cutting fluid used in the cutting process. The use of cutting fluid will affect the cutting force, cutting temperature and machining surface quality.

[0057] Equipment status: record the operating status, fault information, maintenance records, etc. of the cutting equipment. The equipment status will directly affect the stability and processing quality of the cutting process.

[0058] In summary, by recording these data during the cutting process, the cutting process can be comprehensively monitored and analyzed, problems can be discovered in a timely manner, and corresponding measures can be taken to adjust and optimize, so as to improve the quality and efficiency of the cutting process.

[0059] Working principle: This method of adjusting the cutting thickness when cutting the sole material is to prepare the device first, and install a sole cutting device to ensure that the annular knife belt is installed correctly and properly tensioned, and the pulley rotates flexibly.

[0060] Then prepare the sample by selecting the soles for testing. Specifically, the soles of different specifications can be selected from the production line according to certain sampling rules.

[0061] Then, measurement and setting are performed, and the thickness of the sole sample at different positions is measured by using a measuring tool, such as measuring from the front, middle, and rear ends of the sole. After confirming the maximum thickness, the peeling thickness and the lower wheel gap are determined according to the thickness of the sample to be retained. For example, if the required retained thickness is 2.5mm and the maximum thickness measured is 4mm, the peeling thickness is set to 1.5mm and the lower wheel gap is also 1.5mm.

[0062] Then the cutting operation is carried out. The sole sample is sent into the cutting position through the sample feeding device, and the sample is fixed and pressed by the upper and lower pressure rollers. The device is started to drive the annular knife belt to cut the sole sample. The sample is cut into two parts, the upper part is the required sample, and the lower part is discarded.

[0063] Finally, adjust the thickness and record the data. If the surface of the sample is uneven or the thickness is uneven after cutting, slowly adjust the peeling thickness according to the actual situation. If it is found that a certain part of the sample is 0.3mm thicker than the set thickness, the cutting thickness can be increased by 0.3mm and cut again. At the same time, during the entire peeling process, use the data recording system to record the peeling process data of different samples, including the set parameters and the actual adjusted parameters, so that newcomers can refer to it later.
