[0010] Preferably, in any of the above embodiments, the smooth guide post is rotatably connected to the edge of the top of the support template, the high-pressure nozzle is fixedly installed in the middle of the top of the support template, and one end of the high-pressure nozzle is connected to an air guide hole located inside the support template.

[0011] The above technical solution adopts a smooth guide post (made of stainless steel with a polished surface, rotatably connected to the top edge of the support template through a micro bearing, with multiple posts evenly distributed on the edge of each template). Its core function is to reduce the friction between the sock and the template and assist the sock in detaching from the template. Its function is to prevent the sock from getting stuck due to friction and thus detaching smoothly through the smooth surface and rotatable characteristics. At the same time, the circumferential distribution of the guide post can guide the sock in the direction of detachment (detachment along the inclined direction of the guide post).

[0012] Preferably, in any of the above embodiments, the high-pressure air pump assembly includes a high-pressure air pump connected to a PLC control unit, an air guide seat for diverting gas, an electromagnetic air valve connected to a PLC control unit, and an air guide hose for conveying gas.

[0013] The above technical solution is adopted: the high-pressure air pump (vortex air pump, connected to the PLC control unit via analog signal) of the high-pressure air pump group is fixed at the top center of the rotating base. The output end is connected to the air guide seat (aluminum alloy material, with multiple air outlets evenly opened around the circumference to match the solenoid valve) through the flange (the sealing gasket is made of nitrile rubber). Each air outlet of the air guide seat is connected to the solenoid valve (connected to the PLC control unit signal) through the thread. One end of the solenoid valve is connected to the air guide hose (polyurethane material, each corresponding to the air guide hole of the support template) through the quick connector.

[0014] Preferably, in any of the above solutions, the position switch is fixedly installed at one end of the induction support, and the position switch is located above the rotating base and on one side of the support template.

[0015] The above technical solution is adopted: the position switch (inductive proximity switch, fixed to the induction support by screws, with the detection end aligned with the induction metal plate at the bottom of the support template). Its core function is to detect the position of the support template and trigger the feeding signal. Its role is to provide the PLC control unit with precise pause and feeding trigger signals, ensuring that the rotating seat only starts feeding after the template has come to a stop, thus avoiding feeding misalignment.

[0016] Preferably, in any of the above solutions, the guide frame is fixedly installed at one end of the top of the support frame, and the unloading box is attached to one side of the support frame.

[0017] The above technical solution is adopted: the guide frame (fixed to one end of the top of the support frame by bolts, with the feeding end aligned with the bottom of the support template of the unloading station and the discharge end extending to the top of the unloading box), the core function of which is to guide the socks that have detached from the template into the unloading box.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0023] like Figure 1-4 As shown in the figure, a sock processing edge trimming device according to an embodiment of the present invention includes a support frame 1 for support and fixation. A trimming bracket 2 for supporting the socks is fixedly installed at the top of the support frame 1. Several smooth guide posts 3 for guiding the socks are fixedly installed at both ends of the trimming bracket 2. A high-pressure nozzle 4 for feeding the trimmed socks is fixedly installed in the middle of the trimming bracket 2. A high-pressure air pump group 5 for providing pneumatic power is fixedly installed at one end of the high-pressure nozzle 4. The high-pressure air pump group 5 is signal-connected to a PLC control unit for automatic control. The PLC control unit is signal-connected to a position switch 6 for sensing the feeding position. A guide frame 7 for guiding the fed socks is provided on one side of the position switch 6. A feeding box 8 for collecting the socks is provided below the guide frame 7.

[0024] Preferably, the top of the support frame 1 is provided with an installation groove for supporting the trimming bracket 2, and a sensor support is provided on one side of the installation groove for fixed installation with the support frame 1.

[0025] The above technical solution is adopted: the mounting groove at the top of the support frame 1 (welded from Q235 steel) (the width of which is adapted to the rotating seat 22 of the trimming bracket 2) is used to fix the trimming bracket by bolts. The positioning boss at the bottom of the groove ensures that the rotating seat is coaxial with the axis of the frame, avoiding eccentric vibration during rotation. The induction support (aluminum alloy material, fixed to the frame by welding) on ​​one side of the mounting groove is used to install the position switch 6. The distance between the support and the mounting groove ensures that the position switch is accurately aligned with the induction metal plate of the support template 23.

[0026] Its core function is to provide rigid support and precise installation benchmark for the entire trimming device. Its role is to resist the impact force during trimming and unloading through a high-rigidity structure, and to avoid frame deformation affecting processing accuracy. At the same time, the position design of the mounting slot and the induction support ensures that all components work together. During operation: During assembly, first put the rotating seat 22 of the trimming bracket 2 into the mounting slot, and after positioning by the positioning boss, tighten the bolts to fix it. Then fix the position switch 6 to the induction support with screws, and adjust the position of the switch to the distance between it and the induction metal plate of the support template. After the equipment is started, the frame always maintains stable support, ensuring that the rotating seat rotates smoothly and the position switch senses accurately. The control principle achieves non-powered positioning through structural dimensional tolerances, which can ensure the position accuracy of the components without additional adjustment.

[0027] Preferably, the trimming bracket 2 includes a drive motor 21 connected to a PLC control unit, a rotating seat 22 for support, and a support template 23 for shaping and supporting the socks. The drive motor 21 is fixedly installed inside the support frame 1. The output end of the drive motor 21 is fixedly installed with the rotating seat 22 that rotates inside the support frame 1. Several circumferentially distributed support templates 23 are fixedly installed at the top of the rotating seat 22. The bottom of the support template 23 is fixedly installed with a sensing metal plate that senses the position switch 6.

[0028] The above technical solution is adopted: the drive motor 21 (servo motor, connected to the PLC control unit via pulse signal) of the trimming bracket 2 is fixed inside the support frame 1, and the output shaft is connected to the rotating seat 22 (stainless steel material, chrome plated on the surface) via a coupling. Twelve support templates 23 (ABS material, polished surface, shape adapted to the sock outline) are evenly distributed around the top circumference of the rotating seat. The sensing metal plate at the bottom of the template cooperates with the position switch 6 to realize the template position detection.

[0029] Its core function is to support the socks and rotate them to the trimming and unloading stations. Its purpose is to ensure the sock edges are flat and spread out through the shaping structure of the support template (which conforms to the inner shape of the sock), facilitating precise trimming by the trimming blades (not shown). Simultaneously, the circumferential distribution design of the rotating seat enables continuous "loading-trimming-unloading" operations, improving processing efficiency. Operating principle: The PLC control unit drives the motor 21 to rotate the rotating seat 22 at a fixed speed according to a preset program. The support template 23, along with the rotating seat, sequentially passes through the loading station (manual or automated sock-fitting), the trimming station (blade trimming the edges), and the unloading station (position switches 6). When the sensing metal plate at the bottom of the template rotates to the position switch... When the sock is directly below position 6, the position switch triggers a signal, and the PLC control unit controls the rotating seat to pause, preparing for unloading. The process is as follows: The operator at the loading station places the sock onto the support template 23, the edge of the sock unfolds along the template outline, and the rotating seat drives the sock to the trimming station. The cutter trims the excess edge, and after trimming, it rotates to the unloading station. The sensing metal sheet triggers the position switch, and the rotating seat pauses, waiting for the high-pressure nozzle 4 to unload. After unloading, the rotating seat continues to rotate, entering the next cycle. Control principle: The PLC control unit adjusts the rotation speed and pause position through the position feedback of the motor encoder, combined with the sensing signal from the position switch, to ensure that each template stops precisely at the unloading station, achieving continuous automated operation.

[0030] Preferably, in any of the above schemes, the smooth guide post 3 is rotatably connected to the edge of the top of the support template 23, and the high-pressure nozzle 4 is fixedly installed in the middle of the top of the support template 23, with one end of the high-pressure nozzle 4 connected to an air guide hole located inside the support template 23.

[0031] The above technical solution is adopted: smooth guide post 3 (made of stainless steel, with a polished surface, rotatably connected to the top edge of the support template 23 through a micro bearing, with multiple posts evenly distributed on the edge of each template). Its core function is to reduce the friction between the sock and the template and assist the sock in detaching from the template. Its function is to prevent the sock from getting stuck due to friction and thus detach smoothly through the smooth surface and rotatable characteristics. At the same time, the circumferential distribution of the guide post can guide the sock in the direction of detachment (detachment along the inclined direction of the guide post).

[0032] The high-pressure nozzle 4 (made of brass, fixed to the top center of the support template 23 by threads, with the nozzle aligned below the central axis of the template) has an air guide hole connected to one end (located inside the template and sealed to the air guide hose 54). Its core function is to spray high-pressure gas to push the sock away from the template. Its purpose is to overcome the adhesion between the sock and the template through the impact force of the gas, thus achieving automatic feeding. Operation process: When the support template 23 stops at the feeding station, the high-pressure nozzle 4 receives high-pressure gas through the air guide hole. The nozzle sprays high-pressure airflow into the inside of the sock. The airflow pushes the sock downward along the template. During the movement of the sock, the edge contacts the smooth guide post 3. The guide post rotates to reduce friction and guides the sock to detach smoothly from the template. After detachment, the sock moves towards the feed rack 7 under the action of airflow and gravity. Control principle: The nozzle spray angle and position design ensure that the airflow is accurately applied to the center area of ​​the inside of the sock to generate sufficient thrust. The distribution spacing and smooth surface of the smooth guide post ensure that the sock detaches without jamming. The two work together to improve the smoothness of feeding.

[0033] Preferably, the high-pressure air pump assembly 5 includes a high-pressure air pump 51 connected to a PLC control unit, an air guide seat 52 for diverting gas, an electromagnetic air valve 53 connected to a PLC control unit, and an air guide hose 54 for conveying gas. The high-pressure air pump 51 is fixedly installed on the top of the rotating base 22. An air guide seat 52 with an internal gas delivery chamber is fixedly installed at the output end of the high-pressure air pump 51. An electromagnetic air valve 53 connected to the gas chamber is fixedly installed around the circumference of the air guide seat 52. An air guide hose 54 connected to the air guide hole is fixedly installed at one end of the electromagnetic air valve 53.

[0034] The above technical solution is adopted: the high-pressure air pump 51 (vortex air pump, connected to the PLC control unit via analog signal) of the high-pressure air pump group 5 is fixed at the top center of the rotating base 22. The output end is connected to the air guide base 52 (aluminum alloy material, with multiple air outlets evenly opened around the circumference to match the solenoid valve 53) through the flange (the sealing gasket is made of nitrile rubber). Each air outlet of the air guide base is connected to the solenoid valve 53 (connected to the PLC control unit signal) through the thread. One end of the solenoid valve is connected to the air guide hose 54 (polyurethane material, each corresponding to one air guide hole of the support template) through the quick connector.

[0035] Its core function is to provide controllable high-pressure gas to the high-pressure nozzle 4. Its role is to generate stable pressure gas through an air pump, which is then diverted via an air guide seat and controlled by a solenoid valve to achieve precise gas supply to different support templates, avoiding insufficient pressure caused by simultaneous gas supply to multiple templates. Operating principle: The PLC control unit identifies the support template number currently stopped at the unloading station based on the signal from the position switch 6, and then controls the corresponding solenoid valve 53 to open. The high-pressure gas generated by the high-pressure air pump 51 is diverted through the air guide seat 52 to the opened solenoid valve, and then delivered to the high-pressure nozzle 4 through the air guide hose 54 and air guide hole, achieving directional gas supply. After unloading is completed, the PLC control unit controls the solenoid valve to close. When the power is off, the gas supply stops. During operation: High-pressure air pump 51 runs continuously, maintaining stable pressure within the air chamber of air guide seat 52 (feedback from the air pump pressure sensor). When support template 1 stops at the unloading station, the PLC control unit controls solenoid valve 1 to open, supplying gas to nozzle 1 and pushing the socks out. After unloading, solenoid valve 1 closes, and the rotating seat moves template 2 to the unloading station. The PLC control unit then controls solenoid valve 2 to open, and this cycle repeats. Control principle: The PLC control unit achieves directional air supply through the on / off control of the solenoid valves, combined with closed-loop pressure control of the air pump, ensuring stable working pressure for each nozzle and adapting to the unloading needs of different socks.

[0036] Preferably, of any of the above solutions, the position switch 6 is fixedly installed at one end of the induction support, and the position switch 6 is located above the rotating base 22 and on one side of the support template 23.

[0037] The above technical solution is adopted: Position switch 6 (inductive proximity switch, fixed to the sensing support by screws, with the detection end aligned with the sensing metal plate at the bottom of the support template 23), the core function of which is to detect the position of the support template and trigger the feeding signal. Its function is to provide the PLC control unit with precise pause and feeding trigger signals, ensuring that the rotating seat only starts feeding after the template has stopped, thus avoiding feeding misalignment.

[0038] Its detection principle utilizes electromagnetic induction. When the inductive metal sheet (conductor) enters the detection range of the switch, eddy currents are generated in the internal coil of the switch, causing changes in the parameters of the oscillation circuit, which in turn outputs a high-level signal (trigger signal). When the metal sheet leaves the detection range, a low-level signal (reset signal) is output. Operation process: The support template 23 rotates with the rotating seat 22. When the inductive metal sheet at the bottom of the template gradually approaches the position switch 6, the switch outputs a high-level signal. After receiving the high-level signal, the PLC control unit controls the drive motor 21 to decelerate to a stop, and the rotating seat pauses. After the material is unloaded, the PLC control unit controls the motor to start, the inductive metal sheet leaves the detection range, the switch outputs a low-level signal, and the rotating seat continues to rotate. Control principle: By controlling the detection distance and repeatability accuracy of the switch, the consistency of the template's pause position is ensured each time. At the same time, the duration of the high-level signal of the switch (set by the PLC control unit) can cover the entire unloading process, avoiding premature reset that could interrupt the unloading process.

[0039] Preferably, in any of the above schemes, the guide frame 7 is fixedly installed at one end of the top of the support frame 1, and the unloading box 8 is attached to one side of the support frame 1.

[0040] The above technical solution is adopted: the guide frame 7 (fixed to one end of the top of the support frame 1 by bolts, with the feeding end aligned with the bottom of the unloading station support template 23 and the discharge end extending to the top of the unloading box 8) has the core function of guiding the socks that have detached from the template into the unloading box. Its function is to guide the socks to slide along the groove through the "U" shaped groove using gravity and inertia, so as to prevent the socks from falling off and deviating.

[0041] The feeding box 8 (made of polypropylene, attached to one side of the support frame 1, with its top opening aligned with the bottom of the guide frame's discharge end, and the opening area larger than the guide frame's discharge end area) has the core function of collecting socks after feeding. Its large capacity design reduces the frequency of cleaning, and the box's fit to the frame prevents displacement. Operation: After the socks detach from the support template 23, they are propelled by high-pressure gas to the inlet end of the guide frame 7 and fall into the "U"-shaped groove. The socks slide along the inclined groove and fall into the feeding box 8 through the discharge end. As socks continue to fall, the box gradually fills. Operators periodically open the side door of the box to clean the socks. Control principle: The tilt angle of the guide frame controls the sliding speed of the socks, ensuring they fall smoothly into the box. The alignment design between the discharge end and the box opening prevents socks from falling out of the box. Both work together to achieve efficient storage.

[0042] The working principle of this utility model for trimming the edges of socks is as follows: The support frame 1 provides rigid support for the entire unit. A mounting slot at its top secures the trimming bracket 2, and a sensor base secures the position switch 6. After the equipment starts, the PLC control unit drives the drive motor 21 of the trimming bracket 2, causing the rotating seat 22 and the circumferentially distributed support templates 23 to rotate smoothly. At the loading station, the operator places a sock onto the support template 23. The sock's edge unfolds along the template and is positioned with the assistance of smooth guide posts 3. As the rotating seat rotates, the sock is moved to the trimming station for edge trimming. The trimmed support template 23 continues to rotate. When the sensing metal plate at the bottom of the template approaches the position switch 6, the position switch triggers a signal to the PLC control unit. The PLC control unit then stops the rotating seat and simultaneously controls the corresponding solenoid valve of the high-pressure air pump unit 5. When the high-pressure air pump 51 is opened, the high-pressure gas generated is diverted through the air guide seat 52 and delivered to the high-pressure nozzle 4 at the top of the support template via the air guide hose 54. The nozzle sprays airflow to push the socks off the template. The smooth guide post 3 reduces friction due to its rotatable characteristics, which helps the socks to detach smoothly. The detached socks fall into the guide frame 7 under the action of airflow and gravity, and slide along the inclined guide frame to the unloading box 8 below for storage. After storage, the PLC control unit controls the solenoid valve to close and the drive motor to restart. The rotating seat drives the next support template to enter the cycle. All structures work together to realize the continuous operation of sock trimming and automatic unloading.

[0043] Compared with the prior art, the present invention has the following advantages: 1. A rotatable and adjustable trimming bracket 2 is set up to support the socks that need to be trimmed. A high-pressure nozzle 4 is set inside the trimming bracket 2 to spray high-pressure gas generated by the high-pressure air pump group 5 onto the trimmed socks. Under the action of high-pressure gas, the socks are automatically detached from the trimming bracket 2 along the smooth guide post 3. The detached socks are then guided into the unloading box 8 through the guide frame 7, completing the automatic unloading of the trimmed socks. This saves the unloading time of trimmed socks and improves the unloading efficiency of sock trimming, thus effectively improving the efficiency of sock trimming.

[0044] 2. Set a position switch 6 corresponding to the position of the guide rack 7, so that it works in conjunction with the trimming bracket 2 and the high-pressure air pump group 5. According to the feedback of the sensing signal of the position switch 6, the socks at the corresponding position are guided into the interior of the guide rack 7, so that the socks can be unloaded in sequence, improving the convenience and accuracy of sock unloading.
