Description

Technical Field

[0001] This application relates to the field of cutting machine tool technology, and in particular to a shoe insole cutting device. Background Technology

[0002] In the manufacturing process of shoe insoles, the current mainstream technologies generally adopt two technical routes to achieve rapid punching and forming of shoe insoles: mechanical stamping or CNC cutting.

[0003] The core of mechanical stamping is to use customized die-cutting molds in conjunction with the high pressure of hydraulic / pneumatic / mechanical presses to cut sheet-like insole raw materials into shape in one go. Its core advantage is extremely high processing efficiency per unit time and extremely low processing cost per pair. However, the die-cutting mold corresponds one-to-one with the insole size / shape. Due to this limitation, the more frequently the die is changed, the less effective production time there is, resulting in poor production flexibility.

[0004] CNC cutting, through digital 3D modeling and programming, controls a vibrating blade to complete the cutting process along a preset path, eliminating the need for custom-made cutting dies. However, this technology is limited by the product's own structure, resulting in low production efficiency. Summary of the Invention

[0005] This application provides a shoe insole cutting device, which can at least solve the problem of low production efficiency of CNC cutting technology in the process of shoe insole production.

[0006] Specifically, this application provides a shoe insole cutting device, comprising: The housing includes a first drive module and a transmission module. The transmission module includes a power turntable, a transmission rod, a drive shaft, and a sliding sleeve. A cutting tool is mounted on the drive shaft. The sliding sleeve is slidably connected to the drive shaft and is fixedly mounted on the housing. The power turntable is rotatably connected to the housing. The input end of the power turntable is connected to the first drive module to generate circumferential rotational power around the z-axis. One end of the transmission rod is rotatably connected to the output end of the power turntable, and the other end of the transmission rod is rotatably connected to the drive shaft to realize the conversion of the circumferential rotation of the power turntable into the reciprocating motion of the drive shaft along the z-axis. The second drive module is connected to the housing and is used to drive the housing to rotate around the z-axis. The third drive module is connected to the second drive module and is used to drive the housing to move in the xy plane.

[0007] The technical solution adopted in this application can achieve the following beneficial effects: This application improves the tool drive system by converting the circumferential rotational kinetic energy of the power turntable around the z-axis into the reciprocating motion of the tool along the z-axis through the transmission rod and drive shaft. Compared with the traditional eccentric wheel drive, the transmission torque is more uniform and the mechanical vibration is smaller. It can overcome the hardware limitation of "easy vibration at high speed feed" and allow higher feed speeds. At the same time, with the high-precision guidance provided by the sliding sleeve, the frictional resistance and radial offset of the z-axis reciprocating motion are reduced, avoiding cutting defects caused by the tool's inertial offset during high-speed feed. This allows the equipment to operate stably in a higher feed speed range, thereby effectively improving the tool feed speed and increasing the efficiency of the equipment in producing insoles.

[0011] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0012] In related technologies, when using CNC cutting control to cut shoe insoles with a vibrating knife, the feed speed of the knife is limited because shoe insoles are generally made of flexible materials and the cutting contour includes curves. Existing vibrating knife transmission systems (such as direct drive motors and eccentric wheels) are prone to assembly gaps during the processing and assembly of the transmission structure due to their own structural influences. This causes the knife to vibrate during the vibration process, and the higher the vibration frequency, the more severe the tool vibration. This forces the reduction of the vibration frequency, which in turn worsens the cutting effect of the knife. To ensure the cutting quality of the shoe insoles, it is necessary to further reduce the feed speed of the knife. However, the lower the feed speed, the lower the production efficiency of the shoe insoles.

[0013] Therefore, this application provides a shoe insole cutting device. By improving the drive system of the cutter, the circumferential rotational kinetic energy of the power turntable around the z-axis is converted into the reciprocating motion of the cutter along the z-axis through the transmission rod and drive shaft. Compared with the traditional eccentric wheel drive, the transmission torque is more uniform and the mechanical vibration is smaller. It can overcome the hardware limitation of "easy vibration at high speed feed" and allow higher feed speed operation. At the same time, with the high-precision guidance provided by the sliding sleeve, the frictional resistance and radial offset of the z-axis reciprocating motion are reduced, avoiding the cutting defects caused by the inertial offset of the cutter during high-speed feed. This allows the device to operate stably in a higher feed speed range, thereby effectively improving the cutter feed speed and increasing the efficiency of the device in producing shoe insoles, as shown in the following embodiments.

[0014] Example This embodiment provides a shoe insole cutting device, such as... Figure 1 and Figure 2 As shown, the tool 130 is used to control the cutting tool 130 to cut and shape the insole along a preset path. The preset path at least partially corresponds to the outer contour of the insole, so as to achieve one-time cutting and shaping of the outer contour of the insole; as shown Figures 3-8 As shown, the insole cutting equipment specifically includes: The housing 100 includes a first drive module 110 and a transmission module. The transmission module includes a power turntable 121, a transmission rod 122, a drive shaft 123, and a sliding sleeve 124. A cutter 130 is mounted on the drive shaft 123. The sliding sleeve 124 is slidably connected to the drive shaft 123 and is fixedly mounted on the housing 100. The power turntable 121 is rotatably connected to the housing 100. The input end of the power turntable 121 is connected to the first drive module 110, causing the power turntable 121 to generate circumferential rotational power around the z-axis. One end of the transmission rod 122 is rotatably connected to the output end of the power turntable 121, and the other end is rotatably connected to the drive shaft 123, thereby converting the circumferential rotation of the power turntable 121 into axial reciprocating motion of the drive shaft 123 along the z-axis. In this embodiment, the z-axis preferably corresponds to the direction of gravity. The second drive module is connected to the housing 100. The second drive module is used to drive the housing 100 to rotate around the z-axis in order to adjust the cutting edge direction of the tool 130. The third drive module 10 is connected to the second drive module. The third drive module 10 is used to drive the second drive module and the housing 100 to move in the xy plane so that the cutter 130 can move along a preset path and at least cut out the outer contour of the insole from the material.

[0015] During operation, the third drive module 10 provides driving force, causing the second drive module and the housing 100 to move along a preset path in the xy-plane where the material is located. Preferably, the preset path includes the outer contour of the insole projected onto the xy-plane where the material is located, so that the cutter 130 on the housing 100 cuts the material along the outer contour of the insole. The second drive module is responsible for driving the housing 100 to rotate around the z-axis, changing the cutting edge orientation of the cutter 130 so that the cutting edge orientation corresponds to the direction of the cutter's travel. This allows the cutter to adjust its angle as needed during the cutting process to adapt to the cutting requirements of insoles with different shapes and contours. Moreover, the control process does not affect the vibration control of the cutter 130, effectively enhancing the flexibility of the equipment and the control accuracy of the cutter 130. The first drive module 110 serves as the power source for the vibration of the tool 130 along the z-axis. The first drive module 110 controls the power turntable 121 to rotate circumferentially around the z-axis. This circumferential rotation of the power turntable 121 is transmitted to the drive shaft 123 via the transmission rod 122. Due to the sliding engagement between the sliding sleeve 124 and the drive shaft 123 along the z-axis, the drive shaft 123 can only slide along the z-axis. This converts the circumferential rotation of the power turntable 121 into the reciprocating motion of the drive shaft 123 along the z-axis, providing high-precision guidance for the drive shaft 123, reducing frictional resistance and radial offset during the z-axis reciprocating motion, and eliminating radial runout of the tool 130 during its z-axis reciprocating motion. This ensures that even at high vibration frequencies, the tool 130 will not experience additional vibration due to assembly clearances, allowing for higher precision operation. The vibration frequency is increased to improve the upper limit of the feed speed of the tool 130 while ensuring cutting quality. In addition, by converting the circumferential rotation of the power turntable 121 around the z-axis into the axial linear reciprocating motion of the drive shaft 123 along the z-axis, compared with the traditional eccentric wheel drive, the transmission torque is more uniform and smooth, there is no instantaneous impact load, and the movement trajectory of the tool 130 is more stable at high vibration frequency, without the "tool skipping" and "skew" of the traditional structure. When dealing with curved contour processing, the tool 130 can accurately follow the path, avoiding contour deviation and burrs caused by vibration. There is no need to reduce the vibration frequency for stability, thereby further increasing the upper limit of the feed speed of the tool 130. This allows the equipment to complete the insole cutting and forming process efficiently while ensuring the cutting quality of the insole, effectively improving the processing efficiency of the insole.

[0016] It should be noted that the first drive module 110, the second drive module, and the third drive module are existing technologies and can be any power-providing device such as a motor or cylinder, as long as they can achieve the corresponding drive function. This application does not impose any specific limitations on them. In practical applications, the appropriate drive module type can be selected based on factors such as the overall design of the equipment, cost budget, and operating environment. For example, if the power requirements of the equipment are high and the budget is sufficient, a high-performance motor can be selected as the drive module; if the operating environment of the equipment is special, such as the presence of flammable or explosive gases, then explosion-proof cylinders or other drive devices should be selected to ensure the safety and stability of the equipment operation. At the same time, the power, speed, and other parameters of each drive module also need to be reasonably matched and adjusted according to the specific needs of insole cutting to achieve the best cutting effect and production efficiency.

[0017] In some embodiments, to reduce the energy consumption of the second drive module, such as Figures 3-6 As shown, a cylindrical groove 140 along the z-axis can be provided on the top of the housing 100. An annular groove is provided on the inner wall of the cylindrical groove 140 for mounting a bearing 320. The bearing is rotatably mounted on a fixed column 310, allowing the weight of the housing 100 to be borne by the bearing 320 (the fixed column 310 can be fixedly connected to the housing of the second drive module, and the weight of the housing 100 is transmitted to the housing of the second drive module through the bearing 320 and the fixed column 310), instead of directly acting on the output shaft of the second drive module. When the second drive module drives the housing 100 to rotate around the z-axis, the bearing provides support and reduces friction, making the rotation of the housing 100 around the z-axis smoother, thereby reducing the energy required for the second drive module to drive the housing 100 to rotate, achieving the goal of reducing energy consumption. Simultaneously, this design can effectively improve the stability of equipment operation and extend the service life of the equipment. Furthermore, by rationally designing the dimensions of the cylindrical groove 140 and the annular groove, as well as selecting the bearing 320, the performance of the housing 100 rotating around the z-axis can be further optimized to meet the equipment operation requirements under different insole cutting needs.

[0018] In some embodiments, to facilitate the removal of the housing 100 from the equipment, the housing 100 may include an annular pressure plate 141 and an annular transmission gear 142. The housing 100 has a mounting surface 143. The annular pressure plate 141, annular transmission gear 142, and mounting surface 143 are sequentially arranged along the z-axis. The annular pressure plate 141 is connected to the housing 100 via the annular transmission gear 142. The inner wall of the annular transmission gear 142, the bottom wall of the annular pressure plate 141, and part of the mounting surface 143 form an annular groove. The annular transmission gear 142 is connected to the power output end of the second drive module. When it is necessary to disassemble the housing 100, the annular pressure plate 141 can be removed from the annular transmission gear 142 first. At this time, the top opening of the annular groove opens, allowing the housing 100 to be easily removed from the equipment. This disassembly and assembly method is simple and convenient, eliminating the need for disassembly of the second and third drive modules, greatly saving maintenance and repair time, and improving the maintainability of the equipment.

[0019] Specifically, the annular pressure plate 141 and the annular transmission gear 142 are detachably connected, and the annular transmission gear 142 is detachably connected to the housing 100. This design makes the assembly and disassembly of each component more flexible. When the annular transmission gear 142 or the annular pressure plate 141 needs to be repaired or replaced, the corresponding component can be disassembled individually without affecting the normal use of other components, further improving the maintainability and service life of the equipment. Moreover, during the manufacturing process, this detachable connection method also facilitates individual processing and quality control of each component, which is beneficial to improving the production efficiency and product quality of the entire insole cutting equipment. At the same time, by reasonably selecting the detachable connection method, such as bolt connection or snap connection, quick and convenient disassembly and assembly operations can be achieved while ensuring connection strength, meeting the needs of different usage scenarios.

[0020] In some embodiments, to reduce the size of the device, such as Figures 3-8 As shown, a groove 150 can be provided on the housing 100, and the first drive module 110 is disposed in the groove 150. The output end of the first drive module 110 passes through the housing 100. A transmission gear set 111 is also provided on the housing 100. The output end of the first drive module is connected to the input end of the power turntable 121 through the transmission gear set 111. Figure 8As shown, placing the first drive module 110 within the recess 150 effectively utilizes the internal space of the housing 100, preventing the first drive module 110 from being exposed and occupying additional space, thereby reducing the overall size of the equipment and making it more compact and small, facilitating installation, transportation, and storage. Simultaneously, the transmission gear set 111 provides excellent transmission between the first drive module 110 and the power turntable 121. By rationally designing the gear parameters of the transmission gear set, such as the number of teeth and module, different transmission ratios can be achieved to meet the speed and torque requirements of the power turntable 121. Moreover, the transmission gear set 111 provides smooth and reliable transmission, ensuring the accuracy and stability of power transmission, reducing energy loss during power transmission, and improving the equipment's transmission efficiency. Furthermore, connecting the output end of the first drive module 110 through the housing 100 to the transmission gear set 111 creates a more rational internal structure and a clearer relative positional relationship between components, facilitating equipment assembly and maintenance. It should be noted that the transmission gear set 111 is existing technology, and can specifically be a spur gear transmission set, helical gear transmission set, or planetary gear transmission set, etc., as long as it can accurately transmit the power of the first drive module 110 to the power turntable 121. This application does not make specific limitations in this regard. In practical applications, the appropriate type of transmission gear set 111 can be selected according to factors such as the rotational speed and torque requirements of the first drive module 110 and the power turntable 121, as well as the overall spatial layout of the equipment. For example, if the transmission ratio requirement is relatively precise and the space is relatively ample, a spur gear transmission set can be selected; if a larger transmission ratio needs to be achieved in a limited space and the requirement for high transmission smoothness is high, a planetary gear transmission set can be selected. At the same time, the gear material and machining precision of the transmission gear set 111 also need to be reasonably selected according to the working conditions and usage requirements of the equipment to ensure the service life and transmission performance of the transmission gear set 111.

[0021] In some embodiments, to further increase the upper limit of the tool feed rate 130, such as Figure 5 , Figures 7-11As shown, the transmission module can also include a connecting member 125, which is connected to the drive shaft 123. One end of the transmission rod 122 is ball-jointed to the output end of the power turntable 121, and the other end is ball-jointed to the connecting member 125. By using a ball-joint connection, minor assembly errors can be adaptively compensated, avoiding the accumulation of gaps in rigid connections. This also makes the connection between the transmission rod 122, the power turntable 121, and the drive shaft 123 more flexible, allowing free rotation in multiple directions. This effectively reduces constraints and friction during transmission, lowers the risk of vibration and jitter in the tool 130 due to assembly gaps, and increases the upper limit of the tool 130's vibration frequency and feed speed. Simultaneously, the ball-joint connection has a certain buffering effect, absorbing some of the impact force generated during transmission, further reducing the jitter of the tool 130 during vibration. Even at higher vibration frequencies, it ensures the stability of the tool 130's movement. In practical applications, appropriate ball-joint specifications and materials can be selected according to the equipment's working conditions and cutting requirements to ensure the reliability and durability of the ball-joint connection.

[0022] In some embodiments, to facilitate maintenance and updates of the transmission rod 122, a first ball head may be provided on one of the first connecting end 1221 of the transmission rod 122 and the output end of the power turntable 121, and a first ball cup may be provided on the other of the first connecting end 1221 of the transmission rod 122 and the power turntable 121. The first ball head and the first ball cup are matched to achieve a ball joint connection between the transmission rod 122 and the output end of the power turntable 121; the second connecting end 1222 of the transmission rod 122 is provided with The connector 125 has a second ball head and a second ball cup 1253. The connector 125 includes two sub-bodies 1251, each with a portion of the second ball cup 1253. The second ball head and the second ball cup 1253 are matched, and the two sub-bodies 1251 are detachably connected. Preferably, after the two sub-bodies 1251 are fixed together by bolts or clips, the second ball cup 1253 completely encloses the second ball head, achieving a ball joint connection between the transmission rod 122 and the connector 125. This design allows the transmission rod 122 to be removed from the equipment simply by disassembling the connector between the two sub-bodies 1251 when maintenance or replacement is required. This eliminates the need for extensive disassembly of other components such as the drive shaft 123, the second drive module, and the third drive module, greatly simplifying the maintenance process and improving the maintainability of the equipment. Meanwhile, designing the connector 125 as two detachable sub-body 1251 also facilitates the processing and manufacturing of the connector 125 itself, reduces production costs, and improves production efficiency.

[0023] In some embodiments, to avoid a decrease in the cutting accuracy of the tool 130 due to assembly and to improve assembly convenience, such as Figures 9-15As shown, the fixed end of the drive shaft 123 can be connected to the connecting member 125. The connecting member 125 is provided with a mounting groove 1252, a sliding member 127, and a locking member 128. The fixed end of the drive shaft 123 is located in the mounting groove 1252. The fixed end of the drive shaft 123 is provided with a first wedge-shaped surface 1231 and a first truncated cone surface 1232. The opening of the mounting groove 1252 is provided with a second truncated cone surface 1254 that mates with the first truncated cone surface 1232. The sliding member 127 slides along a first direction on the connecting member 125. During at least a portion of the sliding stroke, the sliding member 127 abuts against the first wedge-shaped surface 1231. The sliding stroke includes a first position, in which the first truncated cone surface 1232 and the second truncated cone surface 1254 abut against each other to achieve axial fixation of the drive shaft 123 by the connecting member 125. The locking member 128 is connected to the sliding member 127 and is used to lock and / or unlock the position of the sliding member 127 during the sliding stroke. During assembly, the fixed end of the drive shaft 123 is first placed into the mounting groove 1252. The sliding member 127 and the first wedge-shaped surface 1231 are initially brought into contact. Then, the sliding member 127 is pushed to slide along the first direction. During the sliding process, the sliding member 127 can only slide in the first direction due to the sliding engagement with the connecting member. At the same time, due to the abutment engagement between the sliding member 127 and the first wedge-shaped surface 1231, as the sliding member 127 moves, it will gradually press the fixed end of the drive shaft 123 into the mounting groove 1252. During this process, the first truncated cone surface 1232 and the second truncated cone surface 1254 are automatically brought into close contact, thereby realizing the connection of the connecting member 125 to the drive shaft. The axial direction of shaft 123 is fixed. When the sliding member 127 slides to the first position, the first truncated cone surface 1232 and the second truncated cone surface 1254 completely abut, automatically correcting the axial position of the drive shaft 123, making the axis of the drive shaft 123 automatically parallel to the z-axis, effectively reducing assembly difficulty and eliminating the need for subsequent adjustment and alignment work by assembly personnel. Then, the sliding member 127 is locked in this position by the locking member 128 to prevent the sliding member 127 from moving during equipment operation, ensuring the stability and reliability of the connection between the drive shaft 123 and the connecting member 125. Moreover, when it is necessary to disassemble and maintain the drive shaft 123, simply unlock the locking member 128, slide the sliding member 127 in the opposite direction to separate the first truncated cone surface 1232 and the second truncated cone surface 1254, and the drive shaft 123 can be easily removed from the mounting slot 1252, which is convenient and quick.

[0024] In some embodiments, such as Figures 9-15As shown, the sliding member 127 is provided with a second wedge-shaped surface 1271, and the locking member 128 is provided with a third wedge-shaped surface 1281 and a threaded hole 1282. The device also includes an adjusting bolt 129. The screw of the adjusting bolt 129 passes through the connecting member 125 and is threadedly connected to the threaded hole 1282 of the locking member 128. The nut of the adjusting bolt 129 abuts against the connecting member 125. The third wedge-shaped surface 1281 abuts against the second wedge-shaped surface 1271. The locking member 128 has a sliding stroke relative to the connecting member 125 along the axial direction of the adjusting bolt 129. By rotating the adjusting bolt 129, the locking member 128 is pulled towards the adjusting bolt. When the bolt 129 moves in the direction of movement, the locking member 128 moves in the second direction, preferably perpendicular to the first direction and perpendicular to the z-axis direction. During this process, based on the abutment of the third wedge surface 1281 and the second wedge surface 1271, the moving locking member 128 will push the sliding member 127 to move towards the first wedge surface 1231, forcing the drive shaft 123 to move axially within the mounting groove 1252 until the first truncated cone surface 1232 and the second truncated cone surface 1254 are fully abutted, thereby achieving automatic correction and locking of the axial position of the drive shaft 123. The assembly difficulty is reduced by optimizing the structural design of the transmission module.

[0025] In some embodiments, such as Figures 3-11 As shown, the transmission module also includes an auxiliary shaft 126, which is arranged parallel to the drive shaft 123. The auxiliary shaft 126 is connected to the connecting member 125, and a sliding sleeve 124 is sleeved on the auxiliary shaft 126. The sliding sleeve 124 is fixedly connected to the housing 100. Preferably, the connection method between the auxiliary shaft 126 and the connecting member 125 is the same as the connection method between the drive shaft 123 and the connecting member 125. By setting the auxiliary shaft 126, the tendency of the connecting member 125 to rotate around the z-axis during the transmission process is resisted, further ensuring that the power can be transmitted to the drive shaft 123 more smoothly, allowing the tool 130 to move back and forth along the z-axis more smoothly and at a higher frequency, thereby improving the feed speed of the tool 130.

[0026] In the actual production of insoles, in order to increase output, shift work is usually used to make the equipment run at high load. In high-load operation scenarios, the 130 transmission module of the tool faces extreme heat load. Affected by the difference in thermal expansion coefficient of each component of the transmission module, the thermal deformation of each component of the transmission module is uneven, resulting in abnormal assembly gaps. This not only increases the wear risk between the components of the transmission module, but also reduces the processing accuracy.

[0027] In some embodiments, to cope with high-load operating conditions, such as Figure 5As shown, a mounting cavity 170 can be provided within the housing 100. The connecting member 125 is disposed within the mounting cavity 170. The fixed end of the drive shaft 123 passes through the housing 100 and is connected to the connecting member 125. The connecting member 125 reciprocates within the mounting cavity 170 along the z-axis with the drive shaft 123. An air duct 160 communicating with the mounting cavity 170 is provided on the housing 100. The reciprocating connecting member 125 within the mounting cavity 170, in conjunction with the air duct 160 on the housing 100, enables the power provided by the first drive module 110 to enhance the connection between the mounting cavity 170 and the external environment. Airflow convection between the environment enables the cutting action and heat dissipation to be synchronized in time and space. At the same time, the forced airflow through the transmission rod 122, connecting piece 125 and power turntable 121 located in the installation cavity 170 provides targeted forced air cooling for key components and structures such as the connection between the transmission rod 122, connecting piece 125 and power turntable 121. This effectively reduces the wear of components and the decrease in processing accuracy caused by the difference in thermal expansion coefficients under high load conditions, significantly improves the stability and service life of the equipment, and is conducive to the miniaturization design of the equipment, effectively improving space utilization.

[0028] In some embodiments, a filter device can be installed at the inlet of the air duct 160 to prevent dust and fibers from entering the mounting cavity and avoid additional wear on the components of the transmission module. By optimizing the cross-sectional area and length parameters of the air duct 160, the airflow speed can be controlled, reducing operating noise while ensuring heat dissipation efficiency. For production scenarios with different workloads, the heat dissipation capacity can be dynamically adjusted by adjusting the opening size of the air duct 160 or by adding an axial fan. Furthermore, in the selection of the housing 100 material, aluminum alloy with a high thermal conductivity can be used, combined with surface anodizing treatment, which ensures structural strength and improves thermal radiation efficiency, forming a synergistic effect with the air duct heat dissipation, further enhancing the operational stability of the equipment under high load conditions.

[0029] In some embodiments, to improve heat dissipation, such as Figure 5 As shown, the air duct 160 can be configured to include a first air outlet 161 and a second air outlet 162. The first air outlet 161 and the second air outlet 162 are located on both sides of the connector 125 along the direction of movement of the connector. This design allows the connector 125 to continuously change the flow direction of the gas in the mounting cavity 170 during reciprocating motion, enhancing airflow and thus more effectively removing heat. Furthermore, baffles or fins can be installed in the air duct 160 or the mounting cavity 170 to increase the turbulence of the gas flow and improve heat exchange efficiency. In addition, the size and position of the first air outlet 161 and the second air outlet 162 can be flexibly adjusted according to the heat generation situation in different cutting scenarios to achieve the best heat dissipation effect.

[0030] In some embodiments, to reduce the entry of impurities from the environment into the mounting cavity 170, the opening of the air duct 160 connecting to the environment can be set downward along the z-axis, which corresponds to the direction of gravity. This allows the use of gravity to prevent impurities from easily entering the mounting cavity through the air duct, thereby ensuring the cleanliness of the mounting cavity 170 and preventing impurities from causing wear or affecting the normal operation of the tool 130 transmission module.

[0031] In some embodiments, to improve cutting quality, the first air vent 161 is positioned close to the drive shaft 123, with its axis oriented towards the tool 130 or parallel to the axis of the drive shaft 123. The airflow from the first air vent 161 blows away impurities generated during material cutting by the tool 130, preventing impurities from adhering to the tool 130 or the material surface and affecting cutting accuracy and surface quality. Simultaneously, this arrangement allows for real-time cooling of the tool 130 during cutting, reducing the risk of thermal deformation due to high temperatures and extending the tool's service life. In practical applications, the air outlet angle and speed of the first air vent 161 can be adjusted according to the characteristics of the material being cut (such as fiber content and hardness). For example, for materials prone to fiber lint, the airflow speed can be appropriately increased and the air outlet angle tilted to ensure impurities are effectively blown away from the cutting area.

[0032] In some embodiments, to increase the heat dissipation area, the air duct 160 may include a guide groove 163 disposed on the housing. The second air outlet 162 communicates with the guide groove 163. The design of the guide groove 163 allows airflow to follow the path of the guide groove 163 when entering and exiting the mounting cavity from the second air outlet 162, thereby increasing the contact area with the housing 100 and improving heat dissipation efficiency. The guide groove 163 may be spiral, wavy, or other shapes that increase the complexity of the gas flow path to further extend the contact time between the gas and the housing 100, ensuring that the heat from the housing 100 is fully removed. Preferably, the surface of the guide groove 163 may be roughened to increase the turbulence of the gas and improve heat exchange efficiency. Furthermore, the inlet and outlet of the guide groove 163 may be configured to gradually expand or contract to optimize the gas inlet and outlet speeds and prevent the generation of eddies during the gas inlet and outlet processes, which could affect the heat dissipation effect.

[0033] In some embodiments, to enhance heat dissipation of the connector 125, the first air vent 161 can be positioned corresponding to the connector 125. This allows airflow to directly act on the connector 125 as it enters and exits the mounting cavity 170 from the first air vent 161, carrying away the heat generated by the connector 125 during operation and improving the targeted nature of heat dissipation. Preferably, heat dissipation fins can be provided on the surface of the connector 125 to increase its heat dissipation area and further enhance the heat dissipation effect. The shape and arrangement of the heat dissipation fins can be optimized according to actual conditions. For example, wavy heat dissipation fins can be used to increase the contact area between the gas and the heat dissipation fins, improving heat exchange efficiency. Furthermore, a thermally conductive pad can be provided at the connection between the connector 125 and the drive shaft 123 to reduce thermal resistance, allowing heat to be transferred more quickly from the connector 125 to the drive shaft 123, and then conducted through the drive shaft 123 to the housing 100 and the external environment for heat dissipation.

[0034] In some embodiments, to enhance heat dissipation at the connection between the transmission rod 122 and the power turntable 121, a second air vent 162 can be provided corresponding to the power turntable 121. This allows airflow to directly reach the connection between the transmission rod 122 and the power turntable 121 when entering and exiting the mounting cavity from the second air vent 162, providing targeted heat dissipation for this critical area and effectively reducing component wear and decreased machining accuracy caused by differences in thermal expansion coefficients. Simultaneously, materials with better thermal conductivity or thermally conductive coatings can be used at the connection between the transmission rod 122, the power turntable 121, and the connecting member 125 to reduce thermal resistance, improve heat transfer efficiency, and ensure stable operation of the connection between the power turntable 121, the transmission rod 122, and the connecting member 125 under high-load conditions.

[0035] The above embodiments of this application focus on describing the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be described in detail here.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
