Description

Technical Field

[0001] This invention relates to the field of textile material transfer printing device technology, specifically a rapid printing device for flyknit shoe upper production. Background Technology

[0002] Transfer printing equipment is a core component of textile printing processes, falling under the category of printing presses. Its working principle involves transferring patterns from a transfer film to the fabric surface via heat pressing or other methods. It is widely used in the processing of clothing, shoe uppers, and other products. Specifically, it uses a hot press plate to apply high temperature and pressure, transferring the image from the transfer film to the shoe upper surface to complete the printing operation. Existing similar equipment mainly consists of a machine body, a moving table, and a hot press plate; its overall structure is simple, but its level of automation is relatively low.

[0003] However, existing flyknit shoe upper printing equipment suffers from numerous systemic defects in actual production: First, the flyknit shoe upper and transfer film are placed directly on a moving table without a reliable positioning mechanism. During processing, they are easily displaced and wrinkled due to heat and pressure impacts and conveyor vibrations, directly leading to irreversible quality problems such as misaligned printing and incomplete printing, resulting in batch scrap. Second, the PET base film after transfer printing is mostly removed manually, which is not only labor-intensive and inefficient, but also prone to uneven force during manual film removal, easily pulling on the newly cured printing layer, causing secondary damage such as pattern peeling and edge curling, further reducing product yield. Furthermore, the equipment lacks an integrated online detection mechanism for printing adhesion, and quality control relies on manual visual sampling. Due to subjective factors, the rate of missed and false inspections remains high, making it impossible to achieve closed-loop quality control throughout the entire process. These defects collectively result in poor process linkage and insufficient overall automation of existing equipment, making it difficult to meet the current demand for high-efficiency, high-yield, and high-consistency large-scale high-quality production of flyknit shoe upper printing.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-9 This invention provides a rapid printing device for knitted shoe upper production, including a hot press transfer machine body. The hot press transfer machine body includes a machine body 101, a moving table 102, and a hot press plate 103. The machine body 101 is an integral support frame, integrating power supply, pipelines, and main control circuitry. The body is also equipped with a hot press drive module, a temperature control module, a pressure adjustment module, a moving table drive module, and a main control module for the entire machine. The hot press drive module drives the hot press plate 103 to rise and fall, the temperature control module ensures uniform and stable transfer temperature, the pressure adjustment module can adjust the applied pressure as needed, the moving table drive module drives the moving table 102 to achieve automatic switching of workstations, and the main control module coordinates the timing actions of each mechanism. Its working principle is as follows: The moving table 102 transports the workpiece to the area below the hot press plate 103. Relying on high temperature and pressure, the pattern on the transfer film is transferred to the knitted shoe upper, completing the hot press printing operation. This part is a well-known basic structure of existing hot press transfer equipment and will not be elaborated here. The main body of the hot press transfer machine also includes a positioning mechanism located on top of the moving table 102. The positioning mechanism is used to position and fix the knitted shoe upper and the transfer film. The main body of the hot press transfer machine also includes a film-tearing mechanism arranged above the machine body 101. The film-tearing mechanism includes a movable hollow roller 1104 that can rotate around its own axis. Several air holes 1105 are opened on the side wall of the hollow roller 1104. The air holes 1105 are evenly arrayed along the axial and circumferential directions of the hollow roller 1104 to ensure full coverage of the adsorption and blowing range. The hollow roller 1104 is connected to a bidirectional air passage assembly. The air path assembly is used to selectively extract or blow air into the hollow roller 1104. The main body of the hot press transfer machine also includes a detection mechanism, which is used to detect the adhesion of the printed image after transfer. This device is not a simple superposition of positioning, film tearing, and detection modules, but rather integrates multiple independent processes into one through a deep linkage design of air path and mechanical structure. The positioning mechanism achieves precise fixation of the flyknit upper and the transfer film. With the movable and rotatable hollow roller 1104 with air holes 1105 and the bidirectional air path assembly, the automatic pre-pressing and film tearing of the transfer film are completed. The detection mechanism realizes online detection of the adhesion of the print. It has a high degree of automation, stable positioning, and no damage during film tearing. It effectively solves the problems of insufficient positioning accuracy, low efficiency of manual film tearing, and high missed detection rate of print quality detection in existing equipment, and significantly improves production efficiency and product yield.

[0029] The positioning mechanism includes a shoe upper positioning groove 201 located on the top of the moving table 102, a transfer film positioning frame 202 located around the shoe upper positioning groove 201, and a telescopic component assembled between the transfer film positioning frame 202 and the moving table 102. The contour of the shoe upper positioning groove 201 perfectly matches the shape of the flyknit shoe upper. It adopts a sunken groove structure with a groove depth less than the thickness of the flyknit shoe upper, ensuring that the shoe upper is laid flat without curling. The transfer film positioning frame 202 is a closed-loop frame with an inner circle size larger than that of the shoe upper positioning groove 201, completely covering the edge area of ​​the transfer film. The shoe upper positioning groove 201 achieves the contour limit of the flyknit shoe upper, and the transfer film positioning frame 202 constrains the edge of the transfer film. With the help of the telescopic component, it provides elastic avoidance stroke and can automatically give way when the hot press plate 103 is pressed down, avoiding rigid interference. At the same time, it ensures the relative position stability of the shoe upper and the transfer film, effectively preventing displacement and wrinkling during processing, avoiding printing misalignment and false printing defects from the source, and providing a necessary foundation for high-precision printing.

[0030] The telescopic assembly includes a slide groove 301 formed on the top of the moving stage 102, and a first spring telescopic rod 302 connected between the transfer film positioning frame 202 and the slide groove 301. The first spring telescopic rod 302 is vertically arranged, and its two ends are rigidly fixed to the bottom of the slide groove 301 and the bottom of the transfer film positioning frame 202, respectively. The transfer film positioning frame 202 can slide up and down along the slide groove 301. The slide groove 301 provides stable guidance and sliding stroke for the transfer film positioning frame 202. 02 provides elastic support and reset power for the transfer film positioning frame 202; during the pre-pressing and hot-pressing processes, the transfer film positioning frame 202 is compressed downward along the slide groove 301 by external force to achieve automatic avoidance and prevent rigid collision with the hollow roller 1104 or the hot press plate 103; after the external force disappears, the first spring telescopic rod 302 pushes the transfer film positioning frame 202 to reset along the slide groove 301, ensuring that the transfer film is always in a constrained state and providing a reliable guarantee for continuous production.

[0031] The positioning mechanism also includes an adsorption assembly for adsorbing the edge of the transfer film; the adsorption assembly includes several first chambers 402 opened inside the moving stage 102, a first air passage connecting each first chamber 402, an air extraction pipe 403 connected to the first chamber 402, and an air intake hole 401 opened at the edge of the shoe upper positioning groove 201 and connected to the first chamber 402. The first chamber 402 is a closed cavity, the first air passage adopts an embedded channel, and the whole is sealed to prevent negative pressure leakage; the air intake hole 401 is a small through hole, densely distributed at the edge of the groove opening of the shoe upper positioning groove 201, and the air intake hole 401 is a small through hole. The aperture of 01 is smaller than the gap between the yarns of the flyknit upper fabric, preventing the yarns from being sucked into the chamber. The suction pipe 403 is connected to a negative pressure device, which can form a uniform negative pressure in each of the first chambers 402 through the first air channel. This negative pressure acts on the edge of the flyknit upper through the suction hole 401, tightly adsorbing it in the upper positioning groove 201, forming a secondary fixation in addition to mechanical limitation. This structure effectively counteracts the displacement caused by hot pressing impact and conveying vibration, preventing the upper from wrinkling and shifting. At the same time, it can prevent the edge of the transfer film from lifting and shifting during processing. It is a key auxiliary structure to ensure the printing alignment accuracy and eliminate the defect of false printing.

[0032] The testing mechanism includes several second chambers 501 located inside the mobile platform 102, second air passages connecting each second chamber 501, air blowing pipes 502 connected to the second chambers 501, and several air blowing holes 503 connected to the second chambers 501. The air blowing holes 503 are arranged in a matrix below the printing area of ​​the shoe upper positioning groove 201, all located inside the air intake hole 401, with the air outlet direction vertically upward, covering the entire printing area of ​​the flyknit shoe upper. They are independently set up with the air intake hole 401 and do not overlap. Throughout the process of blowing air outward from the air blowing hole 503 to carry out printing testing, the negative pressure air passage corresponding to the air intake hole 401 remains continuously working, always tightly adsorbing and fixing the flyknit shoe upper to the shoe upper positioning groove 201. Within 01, the airflow impact force generated by the blowing is effectively offset to prevent the shoe upper from shifting or lifting, ensuring the accuracy of the detection position, and the vision sensor 504 is mounted on the moving plate 1101; the blowing hole 503 is arranged in the inner area of ​​the air inlet 401, and the blowing pipe 502 can be connected to an external air source to deliver airflow to each second chamber 501 through the second air channel, and then spray it evenly to the printing area through the blowing hole 503, so that the printing layer is slightly bulged, which makes it easier for the vision sensor 504 to capture and identify defects such as hollowness and peeling; this structure combines air blowing assistance with visual inspection to realize online detection of printing firmness, replace manual visual sampling inspection, effectively reduce the missed detection rate, ensure product quality consistency, and is the key to realizing closed-loop quality control throughout the entire process.

[0033] The film-tearing mechanism includes a movable plate 1101, a first movable module 1106 connected between the movable plate 1101 and the machine body 101, a U-shaped plate 1102, and a lifting assembly connected between the U-shaped plate 1102 and the movable plate 1101. The first movable module 1106 is a linear slide module, fixedly installed on the top crossbeam of the machine body 101, which can drive the movable plate 1101 to perform horizontal reciprocating linear motion. The hollow roller 1104 has round tubes 1103 connected to both ends. The round tubes 1103 and the internal cavity of the hollow roller 1104 are completely connected, and the two are an integral connected structure to ensure unobstructed air passage. The round tubes 1103 pass through the U-shaped plate 1102 and are rotatably connected to the U-shaped plate 1102. The round tubes 1103 and the U-shaped plate 1102 are assembled at the penetration position. Wear-resistant bearings ensure the flexible rotation of the round tube 1103. The film-tearing mechanism also includes a first drive component for driving the rotation of the round tube 1103. The first moving module 1106 can drive the moving plate 1101 to move horizontally along the machine body 101. In conjunction with the lifting component, the height position of the U-shaped plate 1102 and the hollow roller 1104 can be adjusted to realize the position and height adjustment of the hollow roller 1104. The round tube 1103 and the U-shaped plate 1102 are rotatably connected to provide stable rotational support for the hollow roller 1104. The first drive component provides rotational power for the hollow roller 1104, so that the hollow roller 1104 can rotate continuously during the movement. In conjunction with the suction adsorption, the base film is automatically peeled off, completely replacing manual film tearing, greatly improving efficiency and avoiding printing damage.

[0034] The lifting assembly includes an electromagnet 603 fixed to the movable plate 1101, an iron block 602 fixed to the U-shaped plate 1102, and a second spring telescopic rod 601 connected between the movable plate 1101 and the U-shaped plate 1102. The electromagnet 603 and the iron block 602 are arranged vertically opposite each other. When energized, they are magnetically attracted to each other, and when de-energized, the magnetic attraction disappears. The second spring telescopic rod 601 is evenly distributed on both sides of the U-shaped plate 1102. Under normal conditions, it is in a slightly compressed state, which keeps the U-shaped plate 1102 moving downward. In the pre-pressing and film-tearing processes, the second spring telescopic rod 601 provides elastic support and floating stroke for the U-shaped plate 1102 and the hollow roller 1104. When the hollow roller 1104 moves with the movable plate 1101 and interacts with the transfer... When the film contacts, the hollow roller 1104 is compressed by the reaction force of the second spring telescopic rod 601, achieving elastic yielding. This ensures uniform pressure of the hollow roller 1104 on the transfer film, avoiding rigid pressure damage to the printing layer, and also maintains the adhesion between the hollow roller 1104 and the transfer film during movement, ensuring the stability of pre-pressure venting and film removal. When the electromagnet 603 is energized and attracts the iron block 602, the second spring telescopic rod 601 is further compressed, causing the U-shaped plate 1102 and the hollow roller 1104 to rise, making room for the base film to be unloaded. After the power is turned off, the second spring telescopic rod 601 pushes the U-shaped plate 1102 and the hollow roller 1104 to reset, restoring the elastic support state and preparing for the next process cycle.

[0035] The first drive assembly includes a gear 701 fixed to the end of the circular tube 1103, a rack 705 capable of meshing with the gear 701, a sliding assembly connecting the U-shaped plate 1102 and the rack 705, and a guide assembly connecting the rack 705 and the machine body 101. The sliding assembly includes a guide bar 706 connected to the rack 705, a slider 707 slidably connected to the guide bar 706, and a connecting frame 708 connecting the slider 707 and the U-shaped plate 1102. The guide assembly includes multiple connecting blocks 704 connected to the rack 705, a T-shaped guide rod 703 connected to the connecting blocks 704, and a support frame 702 connecting the T-shaped guide rod 703 and the machine body 101. The T-shaped guide rod 703 is disposed through the connecting blocks 704, and is positioned between the hollow roller 1102 and the machine body 101. 04 When the U-shaped plate 1102 moves up and down, the rack 705 is driven to move synchronously up and down along the T-shaped guide rod 703 through the connecting frame 708, slider 707 and guide bar 706, and the gear 701 and rack 705 are always reliably meshed. When the moving plate 1101 drives the U-shaped plate 1102 to move horizontally, the slider 707 is driven to slide along the guide bar 706 through the connecting frame 708, and the gear 701 and rack 705 mesh to drive the round tube 1103 and hollow roller 1104 to rotate synchronously. This structure does not require additional power and directly converts the horizontal movement into the rotational power of the hollow roller 1104. At the same time, through the cooperation of the sliding component and the guide component, the gear 701 and rack 705 are always meshed, so that the film tearing action is synchronous, stable and reliable.

[0036] The bidirectional air passage assembly includes a sleeve 802 fitted around and rotatably connected to the outer side of the circular tube 1103, a bracket 801 connecting the sleeve 802 and the U-shaped plate 1102, a fan 803 communicating with the sleeve 802, and an air pipe 804 connected to the fan 803. The sleeve 802 is a stationary component, while the circular tube 1103 can rotate inside the sleeve 802. A rotary sealing ring is provided at the joint between the two to ensure that the air passage is sealed and leak-proof. The fan 803 is a bidirectional fan that can switch between two working modes: suction and forward blowing. The film-tearing mechanism also includes a mechanism for driving the hollow roller 1104. The second drive assembly is reversed; the second drive assembly includes a rubber wheel 902 that abuts against the circular tube 1103, a splined shaft 901 connected between the rubber wheel 902 and the U-shaped plate 1102, and a power assembly that drives the splined shaft 901 to rotate. The outer surface of the rubber wheel 902 is tightly attached to the outer wall of the circular tube 1103, and power transmission is achieved by static friction. The power assembly includes a work box 903 connected to the air pipe 804, a rotating fan 905 disposed in the work box 903, a first rotating shaft 904 connecting the rotating fan 905 and the work box 903, and a... The first rotating shaft 904 connects to a driving bevel gear 906, a driven bevel gear 909 meshing with the driving bevel gear 906, a second rotating shaft 908 connected to the driven bevel gear 909, a support block 907 connecting the second rotating shaft 908 and the working box 903, a spline sleeve 911 connected to the second rotating shaft 908, and a second moving module 910 connecting the spline sleeve 911 and the support block 907. The working box 903 is a sealed shell, only connected to the air pipe 804. After the airflow enters, it directionally impacts the blades of the rotating fan 905. The spline sleeve 911 has a spline sleeve inside. The key and spline shaft 901 have matching external spline dimensions and can be axially slidably inserted. After insertion, they rotate synchronously and are disconnected by power after separation. The blower 803 can deliver airflow to the working box 903 and the sleeve 802 through the air pipe 804. The sleeve 802 is fitted on the outside of the round tube 1103 and communicates with the inside of its hollow roller 1104. When the blower 803 draws air, the airflow is drawn out through the sleeve 802, creating a negative pressure inside the hollow roller 1104. The edge of the transfer film is adsorbed through the surface air holes 1105. With the help of the first drive component, the hollow roller 1104 is driven to rotate forward to achieve film tearing without damage.When the blower 803 supplies air in reverse, the airflow enters the working box 903 through the air pipe 804, driving the rotating fan 905 to rotate. The first rotating shaft 904 drives the active bevel gear 906 and the driven bevel gear 909 to mesh and transmit power, converting the airflow power into the rotational power of the second rotating shaft 908. The second rotating shaft 908 is connected to the spline shaft 901 through the spline sleeve 911, driving the rubber wheel 902 to rotate. This rotation, through friction transmission, drives the round tube 1103 and the hollow drum 1104 to rotate in reverse. Simultaneously, when the blower 803 supplies air in reverse, the airflow enters the hollow drum 1104 through the sleeve 802 and the round tube 1103, and is blown out from the surface air holes 1105. The airflow propulsion causes the base film wrapped around the surface of the hollow roller 1104 to detach from the roller wall. Under the combined action of airflow blowing and the reverse rotation of the hollow roller 1104, the base film falls due to its own gravity. The second moving module 910 can drive the spline sleeve 911 to slide along the second rotating shaft 908, automatically engaging / disengaging with the spline shaft 901, realizing on-demand access to the reverse rotation power. This structure requires no additional motor, directly utilizing the bidirectional airflow of the blower 803 to simultaneously complete the suction tearing of the film, air blowing unloading, and the reverse rotation of the hollow roller 1104, greatly simplifying the equipment structure, realizing inter-process linkage control, and improving the integration and operational reliability of the equipment.

[0037] The film-peeling mechanism also includes a collection assembly for collecting the peeled base film. The collection assembly includes a collection frame 1001 connected to the top of the machine body 101, a pressing plate 1003 slidably fitted inside the collection frame 1001, and a moving assembly connecting the pressing plate 1003 and the collection frame 1001. The collection frame 1001 is a rectangular frame with an open top, used to receive the fallen transfer film base film. The outer contour of the pressing plate 1003 matches the cross-section of the inner cavity of the collection frame 1001, allowing it to slide smoothly along the inner wall of the collection frame 1001. The moving assembly includes a moving block 1004, a guide rod 1002 connecting the moving block 1004 and the pressing plate 1003, a spring 1005 sleeved on the side wall of the guide rod 1002, a baffle 1006 connected to the moving block 1004, and a push plate 1007 connected to the moving plate 1101. The push plate 1007 can abut against the baffle 1006. When the moving plate 1101 moves towards... When the device resets to the right, the push plate 1007 pushes the baffle 1006, which in turn drives the extrusion plate 1003 to slide to the right via the moving block 1004 and the guide rod 1002, stretching the spring 1005. This causes the extrusion plate 1003 to retract to one side of the collection frame 1001, creating space for newly fallen base film to be collected. When the moving plate 1101 moves to the left, the push plate 1007 disengages from the baffle 1006, and the spring 1005 rebounds, pushing the moving block 1004 and the extrusion plate 1003 to move to the left, extruding and straightening the base film in the collection frame 1001 to prevent it from accumulating loosely. This structure directly utilizes the reciprocating motion of the moving plate 1101 to drive the extrusion action without requiring an additional power source, thus automating the collection and straightening of the base film. This effectively improves the utilization rate of the collection frame 1001 and meets the needs of continuous production for base film processing. This collection component is an auxiliary structure for the entire machine, further improving the fully automated operation chain.

[0038] Working principle: When this rapid printing device for knitted shoe uppers is working, it sequentially completes the entire process of shoe upper positioning, transfer film laying, rolling pre-pressing, hot-press transfer, single-row film tearing, online quality inspection, single-row base film unloading and collection, and column-by-column cyclic operation. The specific operation process is as follows:

[0039] At the start of the operation, the operator first places the knitted upper to be processed flat inside the upper positioning groove 201 on top of the moving table 102, relying on the positioning groove structure to initially limit the position of the upper. Then, the suction equipment is activated, and airflow enters the first chamber 402 inside the moving table 102 through the suction pipe 403, creating a negative pressure inside the first chamber 402. This negative pressure acts on the edge of the knitted upper through the suction hole 401 connected to the first chamber 402, using suction force to firmly fix the upper in the upper positioning groove 201, effectively preventing the upper from shifting or wrinkling during processing, and significantly improving positioning stability. After the upper is fixed, the transfer film is laid inside the transfer film positioning frame 202, completely covering the knitted upper. The transfer film positioning frame 202 limits the boundary of the transfer film, ensuring accurate relative positioning between the upper and the transfer film, laying the foundation for the subsequent hot-press transfer process.

[0040] After material positioning is completed, the moving table 102 is moved along the guide rail of the machine body 101 to directly below the hot press plate 103. At this time, the first moving module 1106 is activated, which drives the moving plate 1101 to move horizontally to the left side of the machine body 101. The moving plate 1101 simultaneously drives the lifting assembly, the U-shaped plate 1102, and the hollow roller 1104 rotatably mounted on the U-shaped plate 1102 to move as a whole. When the hollow roller 1104 moves to the area above the moving table 102, the bottom of the hollow roller 1104 contacts the top of the transfer film positioning frame 202 and pushes the transfer film positioning frame 202 downward, so that the hollow roller 1104 can abut against the top of the transfer film. At this time, the transfer film positioning frame 202 slides downward along the slide groove 301 on the top of the moving table 102 after being subjected to force, and the first spring telescopic rod 302 is compressed and stored.

[0041] Meanwhile, in the first drive assembly, the gear 701 fixed to the end of the circular tube 1103 meshes with the rack 705, causing the gear 701 to rotate and drive the circular tube 1103, which is fixed to it, to rotate synchronously. The circular tube 1103 passes through the U-shaped plate 1102 and is rotatably connected to the U-shaped plate 1102, thereby driving the hollow roller 1104 to rotate continuously around its own axis. The rotating hollow roller 1104 rolls on the surface of the transfer film, which on the one hand fully flattens the transfer film and eliminates wrinkles, and on the other hand gradually removes air bubbles trapped between the transfer film and the flyknit shoe upper, avoiding defects such as printing defects and hollows after hot pressing, and further ensuring the forming quality of hot pressing transfer. During the rolling pre-pressing operation, the second spring telescopic rod 601 in the lifting assembly is compressed by the U-shaped plate 1102, ensuring the resistance effect between the hollow roller 1104 and the transfer film.

[0042] After the rolling pre-pressing is completed, the U-shaped plate 1102 drives the hollow roller 1104 to continue moving to the other side of the moving table 102, and the pre-pressing process ends. Then, the hot press plate 103 is controlled to move downwards to perform a hot press transfer operation on the transfer film and the flyknit upper below. During its downward movement, the hot press plate 103 will contact the top of the transfer film positioning frame 202 and push the transfer film positioning frame 202 downwards along the slide groove 301 to avoid interference from the hot press plate 103's downward pressure, ensuring the normal operation of the hot press transfer.

[0043] After the heat transfer process is completed, the first moving module 1106 moves the moving plate 1101, U-shaped plate 1102, and hollow roller 1104 to the position of the first row of base film. The equipment adopts a single-row operation mode, and the hollow roller 1104 performs the film peeling operation only on a single row of base film at a time. During the operation, the fan 803 is started, and the fan 803 generates negative pressure suction. The airflow passes through the air pipe 804, the sleeve 802 on the support 801, and the round pipe 1103 in sequence into the interior of the hollow roller 1104. Several air holes 1105 opened on the side wall of the hollow roller 1104 simultaneously generate negative pressure suction. Under the continuous meshing transmission of the gear 701 and the rack 705, the hollow roller 1104 keeps rotating. The air holes 1105 tightly adsorb the single row of base film onto the outer surface of the cylinder. As the hollow roller 1104 rolls, the base film of this row is gradually peeled off from the shoe surface and wrapped around the outer wall of the hollow roller 1104, completing the automatic film peeling of the single row of base film.

[0044] After the base film of a single row is removed, the testing mechanism is immediately activated to conduct online quality inspection. The air blowing pipe 502 delivers airflow to the second chamber 501 in the moving table 102. The airflow is evenly sprayed through the air blowing hole 503 onto the printing area where the film has just been removed, causing the printing layer to bulge slightly, making it easier to visually display problems such as air bubbles and peeling. The vision sensor 504 mounted on the moving plate 1101 simultaneously collects images and identifies defects, completing the quality inspection of the printing of that row.

[0045] After the film tearing and inspection are completed, the electromagnet 603 in the lifting assembly is energized. The electromagnet 603 generates magnetic force to attract and fix the iron block 602 on the U-shaped plate 1102, pulling the U-shaped plate 1102 upward, simultaneously lifting the hollow roller 1104 away from the shoe upper area. Subsequently, the first moving module 1106 continues to drive the entire film tearing mechanism to move horizontally, conveying the hollow roller 1104 to directly above the collection frame 1001 at the top of the machine body 101. During the horizontal movement of the moving plate 1101, it drives the push plate 1007 connected to it to move synchronously. The push plate 1007 contacts and pushes the baffle 1006. The baffle 1006 drives the moving block 1004, guide rod 1002 and extrusion plate 1003 to slide as a whole towards the collection frame 1001, and the spring 1005 on the outside of the guide rod 1002 is stretched.

[0046] Once the hollow roller 1104 reaches the designated position above the collection frame 1001, the working mode of the fan 803 is switched from negative pressure ventilation to positive airflow. The high-pressure airflow passes through the air pipe 804, sleeve 802, and round pipe 1103 in sequence, and is then blown outward from the air hole 1105. The airflow propels the single-row base film wrapped around the surface of the hollow roller 1104 to detach from the cylinder wall. At the same time, the second moving module 910 is activated, pushing the spline sleeve 911 to move axially and complete the insertion and engagement with the spline shaft 901. Part of the airflow flows into the working box 903 of the power component along the air pipe 804, and the high-speed airflow impacts the rotating fan 905 inside the working box 903, driving the rotating fan 905 to rotate. The rotating fan 905 drives the driving bevel gear 906 to rotate via the first rotating shaft 904. The driving bevel gear 906 meshes with the driven bevel gear 909, which in turn drives the spline sleeve 911 to rotate via the second rotating shaft 908. The spline sleeve 911 synchronously drives the spline shaft 901 to rotate, and the rubber wheel 902 at the end of the spline shaft 901 rotates accordingly. It also drives the circular tube 1103 to rotate in the opposite direction by friction, ultimately causing the hollow drum 1104 to reverse completely. Under the combined action of airflow stripping and the reversal of the hollow drum 1104, the single-row base film falls into the collection frame 1001 by its own gravity, completing the unloading and collection of the single-row base film.

[0047] After the base film in a single row is unloaded, the first moving module 1106 moves the hollow roller 1104 to the left side of the next row of base film. Then, the power supply to the electromagnet 603 is cut off, the magnetic force disappears, and the U-shaped plate 1102 and the hollow roller 1104 fall back to their working height under the elastic reset action of the second spring telescopic rod 601, ready to perform film tearing and inspection operations on the next row of base film. The equipment cycles through the above steps, completing the processing procedures for all rows sequentially.

[0048] When the moving plate 1101 drives the push plate 1007 to move in the opposite direction and reset, the push plate 1007 and the baffle 1006 gradually separate. The originally stretched spring 1005 releases its elasticity, pushing the guide rod 1002, the moving block 1004 and the squeezing plate 1003 to slide in the opposite direction and reset. During the movement, the squeezing plate 1003 squeezes and straightens the base film accumulated in the collection frame 1001, reduces the space occupied by the base film and increases the material collection capacity.

[0049] After all the columns of the flyknit upper have been processed, the moving table 102 is pulled along the guide rail to move out in the opposite direction, and the finished upper is taken out, thus completing the entire printing process.
