Description

Technical Field

[0001] This invention relates to the field of Goodyear sole bonding technology, specifically to a sole bonding device equipped with a double-sided adhesive coating mechanism. Background Technology

[0002] The sole bonding equipment is the core machinery in the shoe manufacturing production line that firmly bonds the upper and sole of the shoe through adhesive bonding or sewing. Taking Goodyear welt as an example, its bonding process is far more complex than that of ordinary glued shoes. The equipment first uses a motor to drive the rotating shaft to precisely position the glue ejector mold directly above the sole. Under the action of a cylinder, the glue ejector mold is pressed into the inside of the sole, and the glue ejector holes on the bottom and around the perimeter are simultaneously extruded with adhesive to achieve uniform glue application. The sealing rubber then seals the holes to prevent leakage. Subsequently, the mold is pressed down to complete the initial bonding of the upper and sole under pressure. The special feature of the Goodyear welt process is that after the welt is sewn, waterproof welt glue is applied to the welt seam to completely seal the pinholes and prevent water seepage. A mixture of cork chips and latex is filled between the midsole and outsole. After bonding, a coconut shell is used to pound out the interface air to ensure that the welt line is tightly squeezed, ultimately achieving a high standard of bonding with no loose glue on the upper and no air trapped in the sole.

[0003] In existing technologies, traditional shoe sole gluing equipment generally suffers from problems such as large size and complex structure. The machine is heavy and occupies a large area, making it inconvenient to move between different workstations and resulting in extremely poor flexibility. At the same time, such equipment is expensive, and the purchase and maintenance costs far exceed the affordability of small workshops. As a result, some workshops still rely on manual gluing. However, manual gluing has many drawbacks. Operators find it difficult to accurately control the amount of glue dispensed and the gluing path, resulting in uneven glue layer thickness, frequent glue overflow or missing glue at the edges, which directly affects the bonding strength and appearance quality of the shoe sole and upper. In addition, manual gluing is much slower than mechanical operation, takes a long time to process a single pair of shoes, and has low overall production efficiency. Moreover, long-term repetitive operation can easily cause worker fatigue, further exacerbating the fluctuation of gluing consistency and causing unstable product yield. This seriously restricts the improvement of production capacity and the shortening of delivery cycle. To address this, we propose a shoe sole bonding equipment with a double-sided gluing mechanism. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This shoe sole bonding equipment, equipped with a double-sided gluing mechanism, integrates seven functional modules based on a support component: a shoe positioning mechanism, a displacement component, a continuously variable transmission (CVT) mechanism, an oil pump component, an adhesive delivery mechanism, a kinetic energy on / off clutch mechanism, and a drive mechanism. Two gluing units are symmetrically arranged on both sides, enabling automatic positioning of the shoe body and sole body, synchronous double-sided gluing, and continuously variable speed adjustment. The equipment continuously supplies adhesive to the shoe body via the oil pump component, controlled by the kinetic energy on / off clutch mechanism. The continuously variable speed mechanism then drives the gluing units to move horizontally along the displacement component at an adjustable speed to complete the gluing operation. The drive mechanism synchronously adjusts the distance between the two gluing units and works in conjunction with the continuously variable speed mechanism to drive the overall operation. This equipment replaces the traditional heavy-duty machine body with a lightweight aluminum alloy frame, significantly reducing equipment size and cost. Simultaneously, the double-sided gluing and continuously variable speed technologies significantly improve gluing uniformity and production efficiency, effectively solving the pain points of traditional equipment such as large size, complex structure, high price, uneven gluing, and low efficiency. This allows even small workshops to achieve high-quality automated bonding production. Attached Figure Description

[0048] 11. The sole itself. Detailed Implementation

[0049] 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.

[0050] Please see Figures 1-3As shown, the present invention provides a technical solution: a shoe sole bonding device with a double-sided adhesive coating mechanism, comprising a support component 1, a shoe body 10, and a shoe sole body 11. A shoe positioning mechanism 2 for positioning the shoe body 10 and the shoe sole body 11 is provided on one side of the upper center of the support component 1. Two adhesive coating units 9 are provided on one side of the shoe positioning mechanism 2 for uniformly applying adhesive to the two sides of the shoe body 10 and the shoe sole body 11 that are close to each other. A displacement component 3 is provided at the lower end of the two adhesive coating units 9, and a continuously variable transmission mechanism 4 for moving the two adhesive coating units 9 is provided at the upper end of the displacement component 3. The displacement component 3 assists in continuously variable transmission. Mechanism 4 moves horizontally in a linear motion. The upper end of the continuously variable transmission mechanism 4 is equipped with an oil pump assembly 5 for controlling the continuously variable transmission mechanism 4 to achieve continuously variable speed. The upper end of the continuously variable transmission mechanism 4 is equipped with an adhesive delivery mechanism 6 for pumping adhesive liquid. Inside the oil pump assembly 5, on one side, is a kinetic energy on / off clutch mechanism 7 for controlling the start and stop of the adhesive delivery mechanism 6. On one side of the continuously variable transmission mechanism 4, there is a drive mechanism 8 for controlling the distance between the two adhesive application units 9. The two adhesive application units 9 also follow the continuously variable transmission mechanism 4 to operate synchronously through the drive mechanism 8. The drive mechanism 8 is also used to drive the continuously variable transmission mechanism 4 to operate and move horizontally on the displacement assembly 3.

[0051] Furthermore, this shoe sole bonding equipment, equipped with a double-sided adhesive coating mechanism, uses the support component 1 as a base and integrates seven functional modules: a shoe positioning mechanism 2, a displacement component 3, a continuously variable transmission mechanism 4, an oil pump component 5, an adhesive delivery mechanism 6, a kinetic energy on / off clutch mechanism 7, and a drive mechanism 8. Two adhesive coating units 9 are symmetrically arranged on both sides to achieve automatic positioning of the shoe body 10 and the sole body 11, synchronous double-sided adhesive coating, and continuously variable speed adjustment. The equipment continuously supplies adhesive through the oil pump component 5 driving the adhesive delivery mechanism 6, and controls its start and stop via the kinetic energy on / off clutch mechanism 7, and then through the continuously variable transmission mechanism. The structure 4 drives the glue application unit 9 to move horizontally along the displacement component 3 at an adjustable speed to complete the glue application operation. The drive mechanism 8 synchronously adjusts the distance between the two glue application units 9 and works with the stepless speed change mechanism 4 to drive the overall operation. This equipment replaces the traditional heavy machine body with a lightweight aluminum alloy frame 301, which greatly reduces the size and cost of the equipment. At the same time, the double-sided glue application and stepless speed change technology significantly improve the uniformity of glue application and production efficiency, effectively solving the pain points of traditional equipment such as large size, complex structure, high price, uneven glue application, and low efficiency, enabling small workshops to achieve high-quality automated bonding production.

[0052] In the preferred embodiment of this technical solution, please refer to Figure 4As shown, the support assembly 1 includes a first base plate 101. A semi-circular docking plate 102 is fixedly connected to the center of one side of the first base plate 101. Two strip connecting plates 103 are fixedly connected to one end of the center of the other side of the first base plate 101. Two first guide rails 104 are fixedly connected to the center of the upper end of the first base plate 101 near one end of the two strip connecting plates 103. A rubber storage tank 105 is provided on the upper end of the semi-circular docking plate 102. A lid 106 is detachably assembled on the upper end of the rubber storage tank 105. Material picking tubes 107 are fixedly sleeved at both ends of the center of the lid 106. A docking hose 108 is fixedly sleeved at the upper outlet end of the two material picking tubes 107.

[0053] Furthermore, the first base plate 101 serves as the load-bearing base of the entire machine. The semi-circular docking plate 102 at the center of one side supports the adhesive storage tank 105. The tank cover 106 covers the storage tank to form a sealed storage space. The material taking pipes 107, which are fixedly sleeved at both ends inside, extend into the adhesive liquid. The upper end is connected to the subsequent adhesive liquid conveying mechanism 6 through the docking hose 108, so as to realize the continuous guidance of the adhesive liquid from the storage tank to the conveying system. Under the action of pump pressure, the adhesive liquid enters the docking hose 108 through the material taking pipe 107, ensuring that the adhesive supply path is sealed and leak-free. This structure integrates the adhesive storage with the equipment body, eliminates the need for external adhesive supply pipelines, reduces the risk of interface leakage, and reduces residual adhesive waste. The detachable assembly method of the tank cover 106 facilitates daily adhesive addition and cleaning and maintenance. The overall structure is compact, reducing the equipment footprint and the difficulty of handling.

[0054] In the preferred embodiment of this technical solution, please refer to Figure 5As shown, the shoe positioning mechanism 2 includes two first pneumatic telescopic rods 201 and two first guide sleeves 202. The two first pneumatic telescopic rods 201 are respectively fixedly connected to the upper ends of two strip-shaped connecting plates 103.

A second base plate 203 is fixedly connected to the upper end of the two first guide sleeves 202. A first ear piece 204 is fixedly connected to the center of each of the two parallel and far apart sides of the second base plate 203. The telescopic ends of the two first pneumatic telescopic rods 201 are respectively fixedly connected to one side of the two first ear pieces 204. A longitudinal guide tube 205 is fixedly connected to the center of the upper end of the second base plate 203 near the four opposite corners. A second guide tube 205 is fixedly connected to the center of the upper end of the second base plate 203 near both sides. A U-shaped positioning frame 207 is fixedly connected to one end of the upper center of the second base plate 203, and a first hydraulic rod 208 is fixedly sleeved inside the U-shaped positioning frame 207. Second guide sleeves 209 are slidably sleeved on the upper outer sides of the two second guide rails 206. Movable blocks 2010 are fixedly connected to the upper ends of the two second guide sleeves 209. The telescopic end of the first hydraulic rod 208 on one side is fixedly connected to the movable block 2010. Pulleys 2011 are rotatably sleeved on both parallel and distant sides of the two movable blocks 2010 via bearings. First guide rods 2012 are slidably sleeved inside the four longitudinal guide tubes 205. A lifting platform 2013 is fixedly connected to the upper end of the four first guide rods 2012. The upper center of the lifting platform 2013... A detachable shoe support 2014 is installed at the shoe body 10, which is detachably fitted onto the outside of the shoe support 2014. Side plates 2015 are fixedly connected to the lower center of the lifting platform 2013 on both sides. An oblique groove 2016 is formed through the center of each side plate 2015, and two pulleys 2011 are slidably fitted inside the oblique groove 2016. A first support plate 2017 is fixedly connected to the upper end of the lifting platform 2013 near the two first pneumatic telescopic rods 201. A strip support horizontal plate 2018 is fixedly connected to the upper end of the first support plate 2017. The strip support horizontal plate 2018 is positioned directly above the shoe support 2014, and a second pneumatic telescopic rod is fixedly fitted into the center of the strip support horizontal plate 2018. In 2019, a vacuum suction cup 2020 is fixedly connected to the lower telescopic end of the second pneumatic telescopic rod 2019. A second guide rod 2021 is fixedly connected to the upper center of the vacuum suction cup 2020 at each of the four diagonal points. The four second guide rods 2021 are longitudinally slidably sleeved inside the strip support plate 2018 at the four diagonal points. The sole body 11 is adsorbed onto the lower end of the vacuum suction cup 2020. The displacement component 3 includes a lightweight aluminum alloy frame 301, which is fixedly connected to the upper end of the first base plate 101 near the semi-circular docking plate 102. A fixed support plate 302 is fixedly connected to the upper end of the lightweight aluminum alloy frame 301, and a docking rack 303 is fixedly connected to the upper center of the fixed support plate 302 at one side.A lightweight aluminum alloy frame 301 has several first guide rails 304 fixedly connected to its upper center near another location. Each first guide rail 304 has a sliding base 305 at its upper end. The sliding base 305 has several first guide grooves 306 extending through its lower center. These first guide grooves 306 are slidably fitted onto the upper outer sides of the first guide rails 304.

[0055] Furthermore, the two first pneumatic telescopic rods 201 drive the first ear piece 204 to move the second base plate 203 along the first guide rail 104, realizing the lateral coarse positioning of the shoe positioning mechanism 2. The first hydraulic rod 208 pushes the movable block 2010 to slide along the second guide rail 206. Through the oblique constraint of the pulley 2011 in the oblique slot 2016, the horizontal displacement is converted into the vertical lifting motion of the lifting platform 2013 along the four first guide rods 2012, thereby precisely adjusting the height of the shoe inner support 2014 to adapt to different shoe shapes. The second pneumatic telescopic rod 2019 drives the vacuum suction cup 2020 along the four second guide rods 202. 1. Longitudinal fine-tuning: The sole body 11 is stably adsorbed onto the lower end of the vacuum suction cup 2020. The first support vertical plate 2017 and the strip support horizontal plate 2018 provide top limiting support for the upper. This mechanism achieves six-degree-of-freedom precise positioning of the upper and sole through pneumatic, hydraulic and vacuum triple drive. The first pneumatic telescopic rod 201 is responsible for lateral displacement adjustment, the first hydraulic rod 208 is responsible for vertical height, and the vacuum suction cup 2020 is responsible for sole adsorption, fine-tuning and final pressing. Each degree of freedom does not interfere with the others, and the positioning accuracy is high, effectively avoiding the offset error during manual alignment, and providing a stable and reliable positioning benchmark for subsequent double-sided gluing.

[0056] A lightweight aluminum alloy frame 301 is fixed to the upper end of the first base plate 101. The fixed support plate 302 on it supports the docking rack 303 and several first guide rails 304. The sliding base 305 achieves low-friction linear motion along the displacement direction through the sliding engagement of the first guide groove 306 and the first guide rail 304. The docking rack 303 meshes with the synchronous gear 4025 in the third protective shell 4026, converting the rotational motion of the continuously variable transmission mechanism 4 into the horizontal linear displacement of the sliding base 305. This allows the glue application unit 9 to move precisely on the displacement component 3 along with the sliding base 305. The lightweight aluminum alloy material significantly reduces the inertia of the moving parts, reduces the drive load, and improves the start-stop response speed and motion stability. The multi-point guiding design of the first guide rail 304 and the first guide groove 306 effectively suppresses the deflection and vibration of the sliding base 305 during high-speed motion, ensuring the accuracy of the motion trajectory of the glue application unit 9 and providing a stable motion platform for continuously variable transmission glue application.

[0057] In the preferred embodiment of this technical solution, please refer to Figures 6-12As shown, the continuously variable transmission (CVT) mechanism 4 includes a first protective shell 401 and a second protective shell 403.

A synchronous gear 4025 is fixedly mounted on the outside of the auxiliary drive shaft 405, away from the auxiliary drive conical chuck 406. An extension plate 402 is fixedly connected to a third protective shell 4026 near the synchronous gear 4025 to protect the synchronous gear 4025. The third protective shell 4026 and the mating rack 303 are connected by gear meshing transmission. Inside the second protective shell 403, at the end away from the first positioning ring 4011, a main drive pipe 4027 is fixedly connected. At the end of the main drive pipe 4027 away from the second extension plate 404, a main drive conical chuck 4028 is fixedly connected.

A secondary drive shaft 4044 is rotatably connected to the end of the first protective shell 401 away from the secondary drive shaft 405 via a bearing. A transmission counterweight 4033 is bolted to the side of the secondary drive shaft 4044 near the transmission synchronous shaft 4031. A second hollow groove 4034 is formed inside the transmission counterweight 4033 near its center. Multiple second guide holes 4035 are formed inside the transmission counterweight 4033 near its center and edge. A second master pump oil pipe 4036 is fixedly connected to the center of one inner wall of the second hollow groove 4034. Multiple oil circuit interchange ends of the second master pump oil pipe 4036 are fixedly connected to second branch pump oil pipes 4037. The oil circuit interaction ends of the pump oil pipe 4037 on the side away from the second main pump oil pipe 4036 are respectively fixedly sleeved inside the transmission counterweight block 4033. Multiple third hydraulic rods 4038 are fixedly connected in a ring at equal intervals near the center of the transmission counterweight block 4033 on the side away from the secondary drive shaft 4044. The oil circuit interaction ends of the multiple third hydraulic rods 4038 are respectively connected to the oil circuit interaction ends of the multiple second branch pump oil pipes 4037 on the side away from the second main pump oil pipe 4036. A secondary drive conical chuck 4039 is fixedly connected to the telescopic ends of the multiple third hydraulic rods 4038 on the side away from the transmission counterweight block 4033. Multiple second guide frames 4040 are fixedly connected to the secondary drive conical chuck 4039 on the side near the center of the transmission counterweight block 4033.Multiple second guide frames 4040 are slidably sleeved inside multiple second guide holes 4035. A second guide tube 4041 is fixedly sleeved at the center of the auxiliary drive conical chuck 4039. The second guide tube 4041 is slidably sleeved outside the second sliding guide post 4030 and the drive synchronous shaft 4031. Multiple second limiting teeth 4042 are equidistantly arranged and fixedly connected in a ring at the end of the inner wall of the second guide tube 4041 away from the auxiliary drive conical chuck 4039. The multiple second limiting teeth 4042 are slidably sleeved inside the second limiting groove 4032. A continuously variable transmission steel belt 4043 is clamped between the auxiliary drive conical chuck 406 and the main drive conical chuck 4018 and the main drive conical chuck 4028 and the auxiliary drive conical chuck 4039. The oil pump assembly 5 includes an oil pump 501. The pad 502 and the oil pump 501 are fixedly connected to the upper center of the second protective shell 403 on one side. The pad 502 is fixedly connected to the upper center of the first protective shell 401. Oil pipes 503 are fixedly connected to both oil circuit interchange ends of the pad 502. One oil pipe 503, away from the oil pump 501, passes through the main drive shaft 4010 and is rotatably sleeved inside the first master pump oil pipe 4015 at one end via a sealed bearing. The other oil pipe 503 passes through the auxiliary drive shaft 4044 and is rotatably sleeved inside the second master pump oil pipe 4036 at one end via a sealed bearing. One oil pipe 503 is fitted inside the pad 502. The outer side of the central shaft 4029, away from the main drive conical chuck 4028, is fixedly connected to the main drive spur gear 4045.

[0058] Furthermore, the drive motor 809 transmits power to the transmission gear 4022 via the first drive shaft 4023 and the first drive gear 4024, driving the main drive shaft 4010 to rotate. The main drive shaft 4010 drives the drive counterweight 4012 to rotate. The first master pump oil pipe 4015 distributes the pressurized oil delivered by the oil pump 501 to multiple second hydraulic rods 4017 via the first branch pump oil pipe 4016. The second hydraulic rods 4017 push the main drive conical chuck 401. 8. Moving radially within the first guide hole 4014 along the first guide frame 4019 changes the clamping radius between the main drive conical chuck 4018 and the auxiliary drive conical chuck 406. Similarly, the transmission counterweight 4033 on the auxiliary drive shaft 4044 side drives the auxiliary drive conical chuck 4039 to synchronously adjust the clamping radius through the second main pump oil pipe 4036, the second branch pump oil pipe 4037, and the third hydraulic rod 4038. The two sets of conical chucks respectively clamp the continuously variable transmission steel belt. At both ends of 4043, as the clamping radius changes continuously, the effective transmission ratio of the continuously variable transmission steel belt 4043 between the main transmission conical chuck 4028 and the auxiliary transmission conical chuck 4039 changes continuously, thereby driving the synchronous shaft 4031 and the drive synchronous shaft 408 to achieve stepless speed change rotation. The meshing of the first limiting tooth 4021 with the first limiting groove 409 and the second limiting tooth 4042 with the second limiting groove 4032 ensures synchronization and anti-slip during the transmission process. The first sliding guide post 407 with the first guide tube 4020 and the second sliding guide post 4030 with the second guide tube 4041 provide axial positioning and torque transmission. This mechanism achieves stepless adjustment of the glue application speed by continuously adjusting the radius of the hydraulically driven conical chuck. The operator can adjust the glue application speed in real time according to different types of glue and shoe types, avoiding the speed change and uneven glue layer problems caused by traditional stepped speed change. At the same time, the symmetrical arrangement of the two sets of conical chucks ensures transmission stability and torque balance.

[0059] Oil pump 501 is fixed to the upper end of the second protective shell 403. After starting, it pressurizes and delivers the adhesive. Pad plate 502 is fixed to the upper end of the first protective shell 401 and integrates two oil delivery pipes 503. One oil delivery pipe 503 passes through the main drive shaft 4010 and enters the first master pump oil pipe 4015 in the drive counterweight block 4012 through a sealed bearing. The other oil delivery pipe 503 passes through the auxiliary drive shaft 4044 and enters the second master pump oil pipe 4036 in the transmission counterweight block 4033 through a sealed bearing. The pressurized oil output by oil pump 501 is diverted by pad plate 502 and simultaneously supplied to the continuously variable transmission. The hydraulic adjustment systems on both sides of mechanism 4 ensure that the conical chucks on the main drive side and the auxiliary transmission side respond and adjust synchronously. The oil supply pipe 503 rotates synchronously with the main drive shaft 4010 and the auxiliary transmission shaft 4044. The sealed bearing ensures the oil circuit sealing during rotation and avoids leakage. This component integrates the power oil source and rotating parts into the same shaft system, eliminating the need for an independent hydraulic station and external pipelines, simplifying the system structure, reducing leakage risk and maintenance costs. At the same time, the dual-path synchronous oil supply ensures the real-time balance of the clamping force on both sides of the continuously variable transmission mechanism 4, avoiding transmission deviation caused by lag in response on one side.

[0060] In the preferred embodiment of this technical solution, please refer to Figures 13-14As shown, the adhesive delivery mechanism 6 includes a third base plate 601, which is fixedly connected to the upper end of the pad 502. First docking plates 602 are fixedly connected to both sides of the upper center of the third base plate 601. An extension plate 603 is fixedly connected to the lower center of one side of one of the first docking plates 602. A third expansion plate 604 is fixedly connected to the side of the extension plate 603 away from the first docking plate 602. A second drive shaft 605 is rotatably sleeved at the center of the extension plate 603 via a bearing. A first drive bevel gear 606 is fixedly connected to the end of the second drive shaft 605 near the third expansion plate 604. A first rotating shaft 607 is rotatably sleeved at the center of the third expansion plate 604 via a bearing. A first transmission bevel gear 608 is fixedly connected to the end of the first rotating shaft 607 near the first drive bevel gear 606. The first drive bevel gear 606 and the first transmission bevel gear 608 are engaged in gear meshing transmission. One of the first docking plates 602 is fixedly... Multiple positioning plates 609 are connected, and a forged crankshaft 6010 is rotatably sleeved inside the multiple positioning plates 609 via bearings. One end of the forged crankshaft 6010 is fixedly connected to the center of the first transmission bevel gear 608 on the side closest to it. Four connecting rods 6011 are rotatably sleeved on the outside of the forged crankshaft 6010 via bearings. Four material extraction pipes 6012 are fixedly connected at the upper center between the two first docking upright plates 602. The upper center of both sides of the four material extraction pipes 6012 are fixed. The device is equipped with a discharge check valve 6013 and a feed check valve 6014. Pistons 6015 are longitudinally slidably fitted inside each of the four extraction pipes 6012. The upper ends of the four connecting rods 6011 are respectively rotatably connected to the lower center of the pistons 6015 through bearings. The discharge ends of the four discharge check valves 6013 are fixedly connected to discharge hoses 6016. The four discharge ends of the two connecting hoses 108 are respectively connected to the feed ends of the four feed check valves 6014.

[0061] Furthermore, the drive motor 809 drives the second drive shaft 605 to rotate via the first drive shaft 4023. The first drive bevel gear 606 on the second drive shaft 605 meshes with the first transmission bevel gear 608 on the first rotating shaft 607, converting the rotation direction and transmitting it to the forging crankshaft 6010. When the forging crankshaft 6010 rotates, its four connecting rods 6011 on the outer side drive the four pistons 6015 to reciprocate linearly within the four extraction pipes 6012. When the piston 6015 moves downward, the feed check valve 6014 opens while the discharge check valve 6013 closes, and the adhesive is sucked into the extraction pipe 6012 through the docking hose 108. When the piston 6015 moves upward, the discharge check valve 6013 opens. When the feed check valve 6014 is closed, the adhesive is forced into the discharge hose 6016. The four suction pipes 6012 alternately suck and discharge, realizing continuous pulse delivery of the adhesive. The discharge hose 6016 guides the adhesive to the upper and lower spray valve blocks 9033 respectively. This mechanism adopts a crankshaft reciprocating positive displacement pump structure. The speed change of the continuously variable transmission mechanism 4 directly changes the reciprocating frequency of the piston 6015, thereby realizing automatic matching of adhesive delivery volume and coating speed, avoiding excessive accumulation or insufficient supply of adhesive. The four-cylinder parallel design ensures the stability of the output flow. The check valve group realizes unidirectional isolation of suction and discharge, avoiding adhesive backflow and mixing, and ensuring that the coating unit 9 obtains a stable and uniform adhesive supply.

The transmission shaft 701 is rotatably connected to one side of the center inside the first expansion plate 402 via bearings. The drive retaining ring 702 is fixedly connected to the main transmission pipe 4027 near the transmission shaft 701. The two electric telescopic rods 703 are fixedly connected to the second expansion plate 404 near the center of the drive retaining ring 702 at opposite ends. The transmission sprocket 704... A spline hole 705 is provided inside the transmission shaft 701 near the drive circlip 702, and a drive sprocket 706 is fixedly sleeved on the outside of the transmission shaft 701 near the drive circlip 702. A chain 707 is sleeved on the outside of the drive sprocket 706 and the transmission sprocket 704. A first sleeve hole 708 is provided inside the transmission shaft 701 away from the spline hole 705.

A second positioning ring 7010 is fixedly connected between the two second lugs 709. A positioning disc 7011 is rotatably sleeved at the center of the second positioning ring 7010 via a bearing. A transmission retaining ring 7012 is fixedly sleeved on the outside of the positioning disc 7011.

The third sliding guide post 7013 is laterally sleeved inside the main drive tube 4027. The first spline shaft 7014 is fixedly connected to the center of the positioning disk 7011 on the side away from the third sliding guide post 7013. The first spline shaft 7014 is slidably sleeved inside the spline hole 705. A second socket hole 7015 is opened through the center of the positioning disk 7011, the third sliding guide post 7013 and the first spline shaft 7014. The second socket hole 7015 is slidably inserted into the outside of the central shaft 4029.

[0063] Furthermore, when the adhesive delivery mechanism 6 needs to operate, the two electric telescopic rods 703 extend, pushing the second positioning ring 7010 to drive the positioning disk 7011 to move axially along the main drive tube 4027. The third sliding guide post 7013 slides within the main drive tube 4027 to provide guidance. The first spline shaft 7014 engages with the spline hole 705 to achieve circumferential locking. The transmission retaining ring 7012 and the drive retaining ring 702 are detachably engaged. At this time, the kinetic energy transmitted to the main drive tube 4027 is transferred to the transmission shaft 701, which drives the second drive shaft 605 to rotate via the drive sprocket 706, chain 707, and transmission sprocket 704. The adhesive delivery mechanism 6 obtains driving force and begins to supply adhesive. When it is necessary to stop supplying adhesive, the two... When the electric telescopic rod 703 retracts, the second positioning ring 7010 drives the transmission retaining ring 7012 to separate from the drive retaining ring 702, and the first spline shaft 7014 slides in the opposite direction from the spline hole 705, breaking the power transmission path. The adhesive delivery mechanism 6 immediately stops operating, while the continuously variable transmission mechanism 4 can still operate independently. This mechanism achieves rapid on / off control of adhesive delivery through the retaining ring clutch driven by the electric telescopic rod 703. It has a fast response speed, simple and reliable structure, and the cooperation between the spline hole 705 and the first spline shaft 7014 ensures the torque transmission accuracy during engagement. The third sliding guide post 7013 prevents circumferential deflection during the engagement process, effectively avoiding adhesive waste and shoe sole contamination caused by misoperation during the adhesive application process.

[0064] In the preferred embodiment of this technical solution, please refer to Figures 15-17As shown, the drive mechanism 8 includes two fixed plates 8010. The two fixed plates 8010 are respectively fixedly connected to the upper and lower ends of the center of the second extension plate 404 away from the drive sprocket 706. A base plate 801 is fixedly connected to the two fixed plates 8010 away from the second extension plate 404. A fourth extension plate 802 is fixedly connected to the center of one side of the base plate 801. A third lug 803 is fixedly connected to the upper and lower ends of the center of the fourth extension plate 802 away from the two fixed plates 8010. A first spline sleeve 804 is rotatably sleeved inside each of the two third lugs 803 through bearings. A third drive shaft 805 is rotatably sleeved to the upper and lower ends of the center of the base plate 801 through bearings.

[0065] Furthermore, the drive motor 809 meshes with the transmission gear 4022 via the first drive shaft 4023, the first drive gear 4024, and the first drive gear 4022, driving the central shaft 4029 to rotate. Simultaneously, the central shaft 4029 drives the main transmission conical chuck 4028 and the main transmission tube 4027 to rotate. The second drive bevel gears 806 on the two third drive shafts 805 mesh with the two second transmission bevel gears 807, and the two synchronous spur gears 808 mesh with the main drive spur gear 4045, respectively, transmitting the rotation of the central shaft 4029 in two paths to the upper and lower first spline sleeves 804. The two synchronous spur gears 808 mesh with the main drive spur gear 4045. The engagement of wheel 4045 converts the rotational motion into the rotation of the glue-applying roller shaft 9032. The four third pneumatic telescopic rods 8012 enable the synchronous increase or decrease of the distance between the two sets of glue-applying units 9. At the same time, the four third pneumatic telescopic rods 8012 can also drive the corresponding glue-applying unit 9 to slide longitudinally along the third guide rod 902 within the fixed plate 8010, realizing independent fine adjustment of the distance between the glue-applying unit 9 and the shoe body 10 and the sole body 11. This mechanism uses a single drive motor 809 to simultaneously achieve stepless speed change drive, which greatly simplifies the power source configuration. The bevel gear transmission realizes the reversing and makes the drive layout more compact.

[0066] In the preferred embodiment of this technical solution, please refer to Figures 18-20As shown, taking the upper glue-applying unit 9 as an example, the glue-applying unit 9 includes a first mating plate 901 and four third guide rods 902.

A fourth lug 9028 is fixedly connected to both ends of the upper center of the movable base plate 9027. A second rotating shaft 9029 is rotatably sleeved via a bearing at the center of the movable base plate 9027 near the end of the stepper motor 9016. A second drive gear 9030 is fixedly sleeved at the lower center of the outer side of the second rotating shaft 9029. The second drive gear 9030 meshes with the movable rack 9010 and the fixed rack 9011. The upper rotating end of the stepper motor 9016 is fixedly connected to the lower end of the second rotating shaft 9029. A second spline sleeve 9031 is rotatably sleeved within the two fourth lugs 9028 via bearings. A tool for evenly applying adhesive is fixedly sleeved at the outer end of the second spline sleeve 9031 away from the second rotating shaft 9029. The adhesive coating roller shaft 9032 has two glue spraying valve blocks 9033 fixedly connected to one end of the movable base plate 9027 near the adhesive coating roller shaft 9032. The outlets of two discharge hoses 6016 are fixedly connected to the inlet ends of the two upper glue spraying valve blocks 9033, and the outlets of the other two discharge hoses 6016 are fixedly connected to the inlet ends of the two lower glue spraying valve blocks 9033. The outlets of the two upper glue spraying valve blocks 9033 are located at the top of the two upper glue spraying valve blocks 9033, and the outlets of the two lower glue spraying valve blocks 9033 are located at the bottom of the two lower glue spraying valve blocks 9033.

[0067] Furthermore, the stepper motor 9016 drives the second rotating shaft 9029 to rotate. The second drive gear 9030 on the second rotating shaft 9029 simultaneously meshes with the movable rack 9010 and the fixed rack 9011, converting the rotational motion into linear motion of the movable rack 9010 along the second guide groove 908. The movable rack 9010 is guided by the connecting bar 9012 and the fourth guide rod 9013 within the fixed rack 9011, driving the movable base plate 9027 to perform precise horizontal movement. The fourth lug 9028 on the movable base plate 9027 is connected to the third through the second spline sleeve 9031. The third spline shaft 9024 is longitudinally slidably sleeved within the first spline sleeve 804, receiving the operating power from the continuously variable transmission mechanism 4. It superimposes the motion of the adhesive roller shaft 9032 with the rotational motion of the continuously variable transmission mechanism 4, so that the adhesive roller shaft 9032 has both a rotating adhesive application motion and a reciprocating sweeping motion along the length of the shoe upper when adhering to it. Simultaneously, the fourth drive shaft 9019 transmits power to the second spline shaft 9018 via the drive pulley 9020, transmission belt ring 9026, and transmission pulley 9025, driving the second docking plate 9017. The inner coating roller shaft 9032 receives auxiliary rotation that matches the movement of the movable base plate 9027. The glue spraying valve block 9033 receives adhesive from the discharge hose 6016. The two upper glue spraying valve blocks 9033 apply adhesive to the lower end of the shoe sole body 11, while the two lower glue spraying valve blocks 9033 apply adhesive to the upper end of the shoe body 10, achieving simultaneous double-sided glue application. This coating unit 9 precisely converts the rotation of the stepper motor 9016 into reciprocating linear motion via a gear and rack mechanism. Combined with the spline shaft drive, it achieves a composite motion trajectory of rotation and reciprocation of the coating roller shaft 9032, allowing the adhesive to... A uniform mesh coating is formed on the contact surface between the upper and the sole, avoiding edge accumulation and insufficient glue in the middle caused by single rotational glue application. The separate design of the glue spraying valve block 9033 realizes independent glue supply on both sides. The open-loop control of the stepper motor 9016 ensures precise adjustment of the reciprocating stroke to adapt to the glue application path requirements of different shoe types. After the glue application is completed, the four glue spraying valve blocks 9033 retract under the drive of the stepper motor 9016. At this time, the second pneumatic telescopic rod 2019 drives the vacuum suction cup 2020 and the sole body 11 to move vertically downward and press the sole body 11 and the shoe body 10 together.
