Description

Technical Field

[0001] This invention relates to the field of footwear manufacturing technology, specifically to a gluing device for shoe soles and uppers used in footwear manufacturing. Background Technology

[0002] Footwear mainly consists of soles and uppers. In the footwear manufacturing industry, the bonding process between the sole and the upper is a core factor affecting the quality of the finished product and production efficiency.

[0003] Currently, while existing shoe sole and upper gluing equipment has improved operational efficiency to some extent, significant technical bottlenecks still exist. For example, most equipment uses a fixed gluing path design, which cannot adaptively adjust the width of the glue line according to the changes in the side contour of the shoe sole and upper, resulting in uneven gluing path and glue overflow during pressing. Although some equipment has introduced hydraulic pressing function, the gluing and pressing processes are often carried out separately, requiring multiple stations to disassemble and cooperate in steps to complete the pressing, which prolongs the production cycle and is prone to causing deviations in the pressing of the shoe sole and upper, affecting the bonding accuracy.

[0004] In summary, there is an urgent need to develop a sole and upper gluing device that integrates adaptive dynamic gluing and highly stable pressing functions to overcome existing technological bottlenecks and improve the uniformity, stability, and production efficiency of the gluing process in footwear production. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a shoe sole and upper gluing device for footwear production. This device features adaptive dynamic adjustment of the glue line width and the stability of the sole and upper pressing process, improving glue uniformity and shoe pressing accuracy, thereby further enhancing production quality and efficiency. It solves the problems of current technologies, such as the inability to adaptively adjust the glue line width according to shoe shape, uneven glue application, glue overflow during pressing, and pressing deviations caused by multi-station, separate pressing processes.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a shoe sole and shoe upper gluing device for footwear production, comprising a lower frame, an upper frame, a support rod, a lower mold, an upper mold, a limiting component, a driving component, and a gluing component. The lower frame and the upper frame are arranged vertically opposite each other and a support rod is installed between them. The upper frame is located on top of the lower frame and has the same structure.

[0009] Both the lower and upper frames consist of a support plate and a platform plate. Hydraulic rods are fixed between the support plate and the platform plate. Hydraulic rods are installed at the four directional corners of the support plate. The output ends of the hydraulic rods are fixed at the corresponding positions on the platform plate, and the hydraulic rods operate synchronously, enabling the platform plate to smoothly achieve height displacement changes. This is used to adjust the distance between the platform plates in the two frames (lower and upper frames).

[0010] Meanwhile, there are four support rods, which are fixed at the four corners of the support plate in the two frames to connect the two frames and provide support for the upper frame.

[0011] The lower mold and the upper mold are movably connected to the platform plates in the lower frame and the upper frame, respectively, and the lower mold and the upper mold are set opposite to each other. The lower mold is installed on the upper part of the lower frame, and the upper mold is installed on the lower part of the upper frame. The lower mold is used to fit the inclined surface, while the upper mold is used to fix the sole of the shoe.

[0012] Two sets of limiting members are provided between the lower frame and the upper frame to limit the swing distance. The limiting members are attached to the sides of the lower mold and the upper mold. The two sets of limiting members are arranged opposite each other. One set is attached to the outside of the lower mold and the upper mold, while the other set is attached to the inside of the lower mold and the upper mold. The two sets of limiting members automatically adjust the distance between them according to the change in the depth of the side contours when the two templates (lower mold and upper mold) move at the same time, so that the width of the glue applied can be automatically adjusted according to the change of the contours on both sides of the two templates.

[0013] A drive unit is movably connected to one end of the lower frame and the upper frame. The drive unit consists of a support plate, a transmission unit one, a transmission unit two, a transmission mechanism, and a rebound mechanism. The middle of the support plate is movably connected to the transmission unit one, and the rebound mechanism is movably connected to the transmission unit one. Both ends of the support plate are movably connected to the transmission unit two. The two transmission units two are respectively connected to the lower mold and the upper mold. The transmission unit one drives the gluing component to swing through displacement changes, realizing the relative swinging gluing operation on the shoe sole and shoe upper. The transmission unit two drives the two connected templates to move synchronously through rotational force.

[0014] When the transmission unit moves to the designated position, it returns to the initial position under the action of the rebound mechanism. Through reciprocating operation, the oscillating operation of the rubber part is realized.

[0015] A transmission mechanism is movably connected between transmission unit one and transmission unit two. The transmission mechanism is used to drive the two transmission units (transmission unit one and transmission unit two) to operate synchronously, so that while the gluing part swings between the two templates, the two templates produce displacement changes, thereby realizing the overall gluing operation of the shoe sole and shoe upper facing each other.

[0016] A bracket is fixed on the support plate, a sleeve plate is fixed on the bracket, and a drive motor is fixed on the side of the sleeve plate. The drive motor is connected to the transmission mechanism and is used to drive the transmission mechanism to operate, so that the two transmission units operate synchronously.

[0017] A gluing component is movably connected between the lower frame and the upper frame. The gluing component consists of a support rod, a swing mechanism, and a glue gun. One end of the support rod is fixed to a support plate, and the other end is fixed to the swing mechanism. A transmission unit is connected to the swing mechanism, and a glue gun is movably connected to the swing mechanism. The glue gun is located between the lower mold and the upper mold. The support rod is used to support the swing mechanism and the glue gun, so that the gluing component is stably positioned between the lower frame and the upper frame. The swing mechanism drives the glue gun to swing, thereby realizing the gluing operation on the sole and upper of the shoe.

[0018] As a further improvement to the above solution, a limiting groove is provided on the platform plate, and a moving block is slidably connected in the limiting groove. A screw hole is provided on the moving block. At the same time, a screw is fixedly provided at the bottom of the lower mold and the upper mold, and one end of the screw is threaded into the screw hole.

[0019] With the above technical solution, the limiting slide is located in the middle of the platform plate and is set along the length of the platform plate. The moving block slides in the limiting slide, thereby driving the corresponding connected lower mold or upper mold to achieve displacement movement.

[0020] As a further improvement to the above solution, stabilizing rollers are rotatably connected to both ends of the platform plate, and the stabilizing rollers are attached to the opposite sides of the lower mold and the upper mold.

[0021] With the above technical solution, the back of the lower mold and the upper mold are flush with the stabilizing rollers at both ends of the corresponding platform plate. When the template moves, the back is attached to the stabilizing rollers to ensure the stability of the template displacement.

[0022] As a further improvement to the above solution, an air bladder is fixed on the lower mold, and an air valve is provided on the side of the lower mold, which is connected to the air bladder.

[0023] Through the above technical solution, the air bladder is designed according to the shape of the foot. When the shoe upper is fitted onto the lower mold, the air bladder fits fully against the bottom of the shoe upper, thereby ensuring the stability during glue application and bonding. Furthermore, the air bladder is inflated by using a valve, which facilitates the adjustment of air supply and deflation during use and makes it easy to store later.

[0024] As a further improvement to the above solution, an installation groove is provided at the bottom of the upper mold, and a spring button is provided on the side of the upper mold, with one end of the spring button passing through the installation groove.

[0025] With the above technical solution, the mounting groove matches the size of the shoe sole in the international standard size. By placing the shoe sole in the mounting groove, the shoe sole is clamped to both sides of the shoe sole by the outward pushing force of the output end of the spring button, thus fixing the shoe sole in the mounting groove.

[0026] As a further improvement to the above solution, the side of the platform plate is provided with an adjustment groove, and the limiting component consists of two connecting plates, which are movably connected to the side of the platform plate in the lower frame and the upper frame, respectively.

[0027] One end of the connecting plate is fixed with an adjustment slider, which is slidably connected within the adjustment groove.

[0028] With the above technical solution, the two sides of one end of the platform plate in the two frames are provided with adjustment grooves, and each set of limiting components is provided with two connecting plates. One connecting plate is located on the side of the platform plate in the lower frame, and the other connecting plate is located on the side of the platform plate in the upper frame. The adjustment slider installed on the side is slidably connected in the corresponding adjustment groove. When the limiting component moves as a whole, the adjustment slider slides in the adjustment groove, thereby improving the stability of the displacement of the limiting component.

[0029] As a further improvement to the above solution, an adjustment rod is movably connected to the other end of the connecting plate. The adjustment rod consists of a sleeve, a sleeve rod, and a mounting rod. One end of the sleeve is movably fitted into the connecting plate, one end of the sleeve rod is movably fitted into the sleeve, and the other end is fixed to the mounting rod. At the same time, a thrust spring is movably fitted to the side of the sleeve rod, and the two ends of the thrust spring are attached between the sleeve and the mounting rod.

[0030] With the above technical solution, when the front end of the mounting rod is subjected to force, the thrust spring is tightened, and at the same time, the sleeve retracts into the sleeve. When the front end of the mounting rod is not subjected to force, the tension of the thrust spring pushes the mounting rod forward, thereby enabling the overall length of the control rod to be adaptively contracted and adjusted according to the magnitude of the force on the front end of the mounting rod.

[0031] As a further improvement to the above solution, a positioning rod is threadedly connected to the side of the connecting plate, and one end of the positioning rod is attached to the side of the sleeve.

[0032] Through the above technical solution, the positioning rod is used to fix the position of the control rod. By rotating the positioning rod clockwise or counterclockwise, the front end of the positioning rod can be made to fit tightly against or detach from the side of the sleeve, which facilitates the disassembly and assembly of the control rod.

[0033] As a further improvement to the above scheme, a limiting mechanism is movably connected to one end of the control rod. The limiting mechanism includes a clamping plate fixed to one end of the sleeve rod, and a rotating wheel is rotatably connected inside the clamping plate. The rotating wheel is in contact with the sides of the lower mold and the upper mold.

[0034] Through the above technical solution, the control rod plays a supporting role and position adaptive extension and retraction adjustment role for the limiting mechanism. By the rotating wheel adhering to the side of the corresponding lower or upper mold, the position of the limiting mechanism is adaptively adjusted according to the depth of the contour when the template is displaced, and with the cooperation of the thrust spring.

[0035] As a further improvement to the above solution, a telescopic rod is fixed between the clamping plates in the lower frame and the upper frame.

[0036] With the above technical solution, both ends of the telescopic rod have retractable output ends, which are fixed between the corresponding clamps in the lower frame and the upper frame, respectively. When the platform plates in the two frames move towards the center at the same time, the output ends at both ends retract into the telescopic rod.

[0037] As a further improvement to the above solution, an adjustment mechanism is installed on the side of the platform plate. The adjustment mechanism includes a stabilizing block fixed to the side of the platform plate, and an adjustment rod is rotatably connected to the stabilizing block. The adjustment rod is threaded into the connecting plate.

[0038] With the above technical solution, adjustment mechanisms are installed on both sides of one end of the platform plate of the two frames to adjust the position of the corresponding limiters. It is necessary to ensure that the positions of the two sets of limiters remain relative after adjustment, so as to effectively limit the distance of the glue-applying parts swinging to both sides.

[0039] As a further improvement to the above solution, the transmission unit includes a movable rod that is movably sleeved on the support plate and the sleeve plate. An extension rod is movably sleeved at one end of the movable rod, and a fixed rod is threadedly connected to the side of the movable rod. One end of the fixed rod is attached to the side of the extension rod.

[0040] With the above technical solution, the moving rod passes through the support plate and the sleeve plate in a horizontal direction, so that the transmission unit 1 is located horizontally at the center of the two frames. Under the drive, the transmission unit 1 realizes the forward and backward reciprocating motion.

[0041] As a further improvement to the above solution, a toothed rod is fixed to one end of the extension rod, and the swing mechanism includes a mounting plate fixed to the support rod, with rotating gears rotatably connected to both ends of the mounting plate, the rotating gears meshing with the side of the toothed rod.

[0042] With the above technical solution, tooth profiles are provided on both sides of the rack and mesh with the corresponding rotating gears. When the transmission unit reciprocates, the rack moves back and forth between the two rotating gears, causing the two rotating gears to rotate in opposite directions at the same time.

[0043] As a further improvement to the above scheme, a swing rod is movably connected to the rotating gear, and a torsion spring is movably connected between the swing rod and the rotating gear. At the same time, the swing rod is attached to the side of the telescopic rod at a set angle.

[0044] With the above technical solution, swing rods are installed at the top and bottom of the rotating gear. Each swing rod is connected to the rotating gear by a torsion spring. When the rotating gear rotates, it drives the swing rods to achieve a swinging effect. When the front end of the swing rod contacts the outer telescopic rod, the torsion spring twists in the opposite direction, causing the swing rod to stop swinging outward. When the swing rod swings inward, the torsion spring also pushes the swing rod to return to its original position.

[0045] As a further improvement to the above solution, a glue gun is fixed to one end of the swing arm, and an interface is provided on the side of the glue gun.

[0046] With the above technical solution, a glue gun is fixed at the front end of each swing rod, so that the glue outlets of at least two glue guns face upward and the glue outlets of two glue guns face downward, and the glue outlets are parallel to the contact surface of the template in the corresponding direction. Thus, when the template moves towards the glue gun, the glue outlet of the glue gun can stably apply glue to the corresponding sole or upper.

[0047] As a further improvement to the above solution, the support rod consists of a connecting pipe and a connecting rod. The connecting rod is movably sleeved inside the connecting pipe, one end of the connecting pipe is fixed to the support plate, and one end of the connecting rod is fixed to the mounting plate.

[0048] Through the above technical solution, support rods are installed on the support plate, and at the top and bottom of the transmission unit one. The front ends of the connecting rods of the two support rods are fixed with mounting plates. The two mounting plates are located at the top and bottom of the two rotating gears to ensure the stability of the rotation of the rotating gears and their meshing with the rack.

[0049] As a further improvement to the above solution, a fixing screw is threaded to the side of the connecting pipe, and one end of the fixing screw is attached to the side of the connecting rod.

[0050] The above technical solution allows the fixing screw to be rotated clockwise or counterclockwise, so that the front end of the fixing screw can be pressed against or detached from the side of the connecting rod. When pressed against, the length of the support rod is fixed, while when detached, the length of the support rod can be adjusted.

[0051] As a further improvement to the above solution, the transmission unit two includes a rotary knob rotatably connected to one end of the support plate, a synchronous gear fixed to one end of the rotary knob, a connecting rod fixed to one end of the synchronous gear, and a plug rod provided at one end of the connecting rod.

[0052] The transmission unit 2 also includes a screw rod threaded onto the movable block, with a plug block fixed at one end of the screw rod and one end of the plug rod inserted into the plug block.

[0053] Through the above technical solution, the transmission unit 2 adopts a separable design. It is inserted into the insertion block by a plug rod. When the synchronous gear rotates, it drives the screw rod to rotate at the same time. Under the force of the screw rod and the internal thread connection of the moving block, the moving block drives the corresponding template to produce displacement changes.

[0054] As a further improvement to the above scheme, the synchronous gears in the transmission unit two at both ends of the support plate are meshed with synchronous toothed belts.

[0055] With the above technical solution, when any synchronous gear rotates, it drives the other synchronous gear to rotate simultaneously through the synchronous toothed belt, thereby realizing the turntable with synchronous rotation of the double helical rod, so that the two templates can move in the same direction at the same time.

[0056] As a further improvement to the above solution, the transmission mechanism includes a transmission gear fixed on the output end of the drive motor, and a transmission groove is provided on the side of the moving rod, in which the transmission gear meshes.

[0057] Through the above technical solution, the output end of the drive motor has the function of bidirectional rotation, and the transmission gear is a toothed gear with a tooth profile at the bottom of the transmission groove. During operation, the output end drives the transmission gear to rotate. Under the action of the transmission gear meshing with the tooth profile in the transmission groove, the moving rod drives the transmission unit as a whole to move forward.

[0058] As a further improvement to the above scheme, the transmission mechanism also includes a drive gear fixed to one end of the transmission gear, a connecting toothed belt meshing on the side of the drive gear, a rotating gear meshing inside the connecting toothed belt, a bevel gear one fixed to one end of the rotating gear, a bevel gear two meshing on the side of the bevel gear one, and a rotating knob fixed to one end of the bevel gear two.

[0059] Through the above technical solution, the transmission gear rotates while driving the drive gear to rotate. At this time, the connecting toothed belt drives the rotating gear to rotate simultaneously, so that bevel gear one and bevel gear two mesh and rotate, thereby causing the rotary knob to drive the synchronous gear to rotate, achieving the effect of rotating the screw rod.

[0060] As a further improvement to the above scheme, a positioning plate is rotatably connected to one end of the drive gear and the rotating gear.

[0061] With the above technical solution, the drive gear and the rotating gear are fixed at both ends of the positioning plate, which improves the stability of gear rotation and prevents the gear from detaching from the toothed belt.

[0062] As a further improvement to the above scheme, the sides of bevel gear one and bevel gear two are rotatably connected with stabilizing plates.

[0063] With the above technical solution, the stabilizing plate is right-angled, and bevel gear one and bevel gear two are fixed at both ends of the stabilizing plate, thereby improving the stability of the meshing of the two bevel gears.

[0064] As a further improvement to the above solution, the rebound mechanism consists of a limiting ring and a tension spring. The limiting ring is fixed to one end of the moving rod, and the tension spring is movably sleeved on the side of the moving rod. At the same time, the two ends of the tension spring are attached between the limiting ring and the support plate.

[0065] With the above technical solution, when the moving rod moves forward to its limit under the force of the meshing rotation of the transmission gear and the transmission groove, the missing tooth of the transmission gear corresponds to the tooth profile in the transmission groove. At this time, under the push of the tension spring, the moving rod drives the entire transmission unit to move backward and return to the initial position. The tooth profile of the transmission gear meshes with the tooth profile in the transmission groove again and rotates, realizing the reciprocating motion of the entire transmission unit.

[0066] Compared with the prior art, the present invention provides a shoe sole and shoe upper gluing device for footwear production, which has the following beneficial effects:

[0067] 1. This shoe sole and upper gluing device for footwear production uses a template designed according to the shape of the sole. When the template moves, the spacing of the gluing component's swing is adaptively adjusted by the limiting component according to the depth of the contour of the side of the template it contacts. With the help of the torsion spring installed on the swing rod, the width of the glue line is dynamically controlled when applying glue to the sole and upper, effectively improving the uniformity and stability of the glue application, avoiding glue overflow caused by uneven glue application during pressing, and avoiding excessive glue waste.

[0068] 2. This shoe sole and upper gluing device, used in footwear production, completes the gluing process on the sole and upper through the synchronous operation of two templates in conjunction with the gluing device. After the two templates are in their initial positions and detached from the front end of the gluing component, the hydraulic rods in the two frames can be controlled to close the platform plates. This allows for direct pressing of the sole and upper without changing workstations, further improving the pressing accuracy of the sole and upper. At the same time, it effectively shortens the footprint and production cycle of traditional step-by-step pressing equipment, reducing equipment investment costs.

[0069] 3. The shoe sole and upper gluing device for footwear production uses a drive motor as a power source and is connected to a transmission mechanism to drive transmission unit one and transmission unit two to operate simultaneously. This allows the gluing part to oscillate while the lower and upper molds move synchronously, achieving a single power source with dual drive effect. At the same time, it effectively improves the consistency and stability of the operation of each functional device during equipment operation.

[0070] 4. The shoe sole and upper gluing device for footwear production uses a threaded connection between the lower and upper molds and the moving block to achieve quick assembly and disassembly and height adjustment. This facilitates the replacement of templates of different sizes and contours in the later stages, thereby effectively improving the flexibility and versatility of the device.

[0071] 5. The shoe sole and upper gluing device for footwear production can be adjusted by changing the positions of the transmission unit, support rod and limiting parts when changing templates of different sizes, so that each functional component can be fully adapted to the templates of different sizes, further improving the flexibility of equipment use.

[0094] 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.

[0095] Example 1

[0096] Please see Figures 1-13 As shown in this embodiment, a shoe sole and upper gluing device for footwear production includes a lower frame 1, an upper frame 2, a support rod 3, a lower mold 4, an upper mold 5, a limiting component 6, a driving component 7, and a gluing component 8. The lower frame 1 and the upper frame 2 are arranged vertically opposite each other, and a support rod 3 is installed between them. The upper frame 2 is located on top of the lower frame 1 and has the same structure.

[0097] Both the lower frame 1 and the upper frame 2 are composed of a support plate 21 and a platform plate 22. A hydraulic rod 23 is fixed between the support plate 21 and the platform plate 22. The hydraulic rod 23 is installed at the four directional corner positions of the support plate 21. The output end of the hydraulic rod 23 is fixed at the corresponding position of the platform plate 22. The hydraulic rod 23 operates synchronously, so that the platform plate 22 can smoothly achieve height displacement change, which is used to adjust the distance between the platform plates 22 in the two frames (lower frame 1 and upper frame 2).

[0098] Meanwhile, there are four support rods 3, which are fixed at the four corners of the support plate 21 in the two frames to connect the two frames and support the upper frame 2.

[0099] The lower mold 4 and the upper mold 5 are movably connected to the platform plate 22 in the lower frame 1 and the upper frame 2, respectively, and the lower mold 4 and the upper mold 5 are arranged opposite to each other. The lower mold 4 is installed above the lower frame 1, and the upper mold 5 is installed below the upper frame 2. The lower mold 4 is used to fit the inclined surface, while the upper mold 5 is used to fix the sole of the shoe.

[0100] It should be further explained that the lower mold 4 and the upper mold 5 are of the same size and are in the same position, and can move horizontally at the same time. When they come into contact with the upper glue part 8, they can apply glue to the opposite surfaces of the shoe upper and the sole.

[0101] Two sets of limiting members 6 are provided between the lower frame 1 and the upper frame 2 to limit the swing distance. The limiting members 6 are attached to the sides of the lower mold 4 and the upper mold 5. The two sets of limiting members 6 are arranged opposite to each other. One set is attached to the outside of the lower mold 4 and the upper mold 5, while the other set is attached to the inside of the lower mold 4 and the upper mold 5. The two sets of limiting members 6 automatically adjust the distance between the two sets of limiting members 6 according to the change in the depth of the side contour when the two templates (lower mold 4 and upper mold 5) move at the same time, so that the glue application part 8 automatically adjusts the width of the glue applied according to the change of the side contours of the two templates.

[0102] A drive unit 7 is movably connected to one end of the lower frame 1 and the upper frame 2. The drive unit 7 consists of a support plate 71, a first transmission unit 72, a second transmission unit 73, a transmission mechanism 74, and a rebound mechanism 75. The first transmission unit 72 is movably connected to the middle of the support plate 71, and the rebound mechanism 75 is movably connected to the first transmission unit 72. The second transmission unit 73 is movably connected to both ends of the support plate 71. The two second transmission units 73 are respectively connected to the lower mold 4 and the upper mold 5. The first transmission unit 72 drives the gluing part 8 to swing through displacement changes, realizing the relative swinging gluing operation on the shoe sole and shoe upper. The second transmission unit 73 drives the two connected templates to move synchronously through rotational force.

[0103] When the transmission unit 72 is displaced to the designated position, it returns to the initial position under the action of the spring mechanism 75. In the reciprocating operation, the oscillating operation of the gluing part 8 is realized.

[0104] A transmission mechanism 74 is movably connected between transmission unit 1 72 and transmission unit 2 73. The transmission mechanism 74 is used to drive the two transmission units (transmission unit 1 72 and transmission unit 2 73) to operate synchronously, so that while the gluing part 8 swings between the two templates, the two templates produce displacement changes, thereby realizing the overall gluing operation of the shoe sole and the shoe upper facing each other.

[0105] A bracket 711 is fixed on the support plate 71, a sleeve plate 712 is fixed on the bracket 711, and a drive motor 713 is fixed on the side of the sleeve plate 712. The drive motor 713 is connected to the transmission mechanism 74 and is used to drive the transmission mechanism 74 to operate, so that the two transmission units operate synchronously.

[0106] A glue-applying component 8 is movably connected between the lower frame 1 and the upper frame 2. The glue-applying component 8 consists of a support rod 81, a swing mechanism 82, and a glue gun 83. One end of the support rod 81 is fixed to the support plate 71, and the other end is fixed to the swing mechanism 82. The transmission unit 72 is connected to the swing mechanism 82. The glue gun 83 is movably connected to the swing mechanism 82. The glue gun 83 is located between the lower mold 4 and the upper mold 5. The support rod 81 is used to support the swing mechanism 82 and the glue gun 83, so that the glue-applying component 8 is stably positioned between the lower frame 1 and the upper frame 2. The glue gun 83 is driven to swing by the swing mechanism 82 to realize the glue application operation of the shoe sole and shoe upper.

[0107] The working principle of the shoe sole and upper gluing device for footwear production proposed in this embodiment is as follows: During use, the shoe upper is placed on the lower mold 4, and the shoe sole is fixed inside the upper mold 5, so that the bottom of the shoe upper is opposite the surface to be bonded to the shoe sole. At this time, the drive motor 713 is controlled to operate, causing the transmission mechanism 74 to drive the two transmission units to operate synchronously, causing the two templates to gradually move from the front end to the rear end. Simultaneously, the gluing component 8 completes the first gluing operation on the opposing surfaces of the shoe sole and shoe upper while swinging. Then, the drive motor 713 is controlled to operate in the reverse direction, causing the two templates to gradually move from the rear end to the front end, while the gluing component 8 swings... In this state, the second gluing operation is completed on the opposing surfaces of the sole and upper. After the second gluing operation is completed, the two templates are in the initial position and completely separated from the front end of the gluing part 8. Then, the output end of the hydraulic rod 23 is controlled to extend outward, so that the platform plate 22 in the two frames drives the two templates to move closer to the center, pressing the opposing surfaces of the sole and upper together for bonding and molding. Before demolding, the upper is first removed from the lower mold 4. Then, the output end of the hydraulic rod 23 is controlled to retract inward, so that the molded shoe body rises to the initial position with the upper mold 5. Then, the sole is separated from the upper mold 5, and the shoe body can be removed.

[0108] Furthermore, a limiting groove 221 is provided on the platform plate 22, and a moving block 24 is slidably connected in the limiting groove 221. A screw hole 241 is provided on the moving block 24. At the same time, a screw 53 is fixedly provided at the bottom of the lower mold 4 and the upper mold 5, and one end of the screw 53 is threadedly connected in the screw hole 241.

[0109] More specifically, the limiting slide 221 is located in the middle of the platform plate 22 and is set along the length of the platform plate 22. The moving block 24 slides in the limiting slide 221, thereby driving the corresponding connected lower mold 4 or upper mold 5 to achieve displacement movement.

[0110] It should be further explained that the width of the moving block 24 matches the width of the limiting groove 221, which improves the stability of the sliding of the moving block 24. The lower mold 4 and the upper mold 5 are threadedly connected to the screw hole 241 by the screw 53 set at one end of the back side, so as to connect with the moving block 24. Thus, when the moving block 24 slides, it drives the corresponding template to achieve displacement movement.

[0111] Furthermore, the threaded connection between the screw 53 and the screw hole 241 not only improves the stability of the connection between the template and the moving block 24, but also facilitates the replacement of templates of different sizes for later use.

[0112] Example 2

[0113] Please see Figure 3 and Figures 5-6As shown, the shoe sole and upper gluing device for footwear production proposed in this embodiment, based on the first embodiment, further includes a platform plate 22 with rotatably connected to both ends of a stabilizing roller 222, which is attached to the opposite sides of the lower mold 4 and the upper mold 5.

[0114] More specifically, the back sides of the lower mold 4 and the upper mold 5 are flush with the stabilizing rollers 222 at both ends of the corresponding platform plate 22. When the template moves, the back sides are attached to the stabilizing rollers 222 to ensure the stability of the template displacement.

[0115] Furthermore, an airbag 41 is fixed on the lower mold 4, and an air valve 42 is provided on the side of the lower mold 4, which is connected to the airbag 41.

[0116] More specifically, the air bladder 41 is designed according to the shape of the foot. When the upper is fitted onto the lower mold 4, the air bladder 41 fits fully against the bottom of the upper, thus ensuring stability during gluing and bonding. Furthermore, the air bladder 41 is inflated by the valve 42, which facilitates the adjustment of air supply and deflation during use and makes it easy to store later.

[0117] It should be further explained that each lower mold 4 is equipped with an air bladder 41 of matching size and expansion size. The size of the lower mold 4 is designed according to the same international standard size, so that when different sizes of lower mold 4 are replaced, the corresponding air bladder 41 can fully fit the same size of shoe upper. By replacing it, the processing of shoe uppers of different sizes can be met.

[0118] Furthermore, the bottom of the upper mold 5 is provided with an installation groove 51, and the side of the upper mold 5 is provided with a spring button 52, one end of which passes through the installation groove 51.

[0119] More specifically, the mounting groove 51 is matched with the size of the shoe sole in the international standard size. By placing the shoe sole in the mounting groove 51, the shoe sole is clamped to both sides of the shoe sole by the outward pushing force of the output end of the spring button 52, thus fixing the shoe sole in the mounting groove 51.

[0120] It should be further noted that the number and position of the spring buttons 52 installed on the side of the upper mold 5 can be set according to the actual force and position of fixing the sole. There are no restrictions here. The spring button 52 is specifically composed of a cylinder and a fixing button. The cylinder is fixed on the side of the upper mold 5, and the fixing button passes through the mounting groove 51. By installing a spring between the cylinder and the fixing button, the front end of the fixing button is pressed tightly against the side of the sole under the push of the spring, thereby fixing the sole.

[0121] Furthermore, when replacing the lower mold 4, it is also necessary to replace the upper mold 5 of the same size to ensure that the upper and sole of the same size are fully bonded.

[0122] In addition, the outlines of the lower mold 4 and the upper mold 5 match the side outline of the sole to be pressed. The outlines of the two templates are 0.4cm-1cm wider than the outline of the sole. The templates are not limited to any type of footwear for gluing, such as sports shoes, dress shoes, and casual shoes. No restrictions are placed here.

[0123] Example 3

[0124] Please see Figures 2-7 As shown, the shoe sole and upper gluing device for footwear production proposed in this embodiment, based on embodiment two, further includes an adjustment groove 223 on the side of the platform plate 22, and the limiting member 6 is composed of two connecting plates 61, which are movably connected to the side of the platform plate 22 in the lower frame 1 and the upper frame 2 respectively.

[0125] One end of the connecting plate 61 is fixed with an adjusting slider 611, which is slidably connected within the adjusting groove 223.

[0126] More specifically, the two sides of one end of the platform plate 22 in the two frames are provided with adjustment grooves 223, and each set of limiting members 6 is provided with two connecting plates 61. One connecting plate 61 is located on the side of the platform plate 22 in the lower frame 1, and the other connecting plate 61 is located on the side of the platform plate 22 in the upper frame 2. The adjustment slider 611 installed on the side is slidably connected in the corresponding adjustment groove 223. When the limiting member 6 moves as a whole, the adjustment slider 611 slides in the adjustment groove 223, thereby improving the stability of the displacement of the limiting member 6.

[0127] Furthermore, the other end of the connecting plate 61 is movably connected to an adjusting rod 62. The adjusting rod 62 consists of a sleeve 621, a sleeve rod 622, and a mounting rod 623. One end of the sleeve 621 is movably sleeved in the connecting plate 61, one end of the sleeve rod 622 is movably sleeved inside the sleeve 621, and the other end is fixed on the mounting rod 623. At the same time, a thrust spring 624 is movably sleeved on the side of the sleeve rod 622, and the two ends of the thrust spring 624 are attached between the sleeve 621 and the mounting rod 623.

[0128] More specifically, when the front end of the mounting rod 623 is subjected to force, the thrust spring 624 is tightened, and at the same time, the sleeve rod 622 retracts into the sleeve 621. When the front end of the mounting rod 623 is not subjected to force, the tension of the thrust spring 624 pushes the mounting rod 623 forward, thereby enabling the overall length of the control rod 62 to be adaptively contracted and adjusted according to the magnitude of the force on the front end of the mounting rod 623.

[0129] Furthermore, a positioning rod 612 is threadedly connected to the side of the connecting plate 61, and one end of the positioning rod 612 is attached to the side of the sleeve 621.

[0130] More specifically, the positioning rod 612 is used to fix the position of the control rod 62. By rotating the positioning rod 612 clockwise or counterclockwise, the front end of the positioning rod 612 can be pressed against or detached from the side of the sleeve 621, which facilitates the disassembly and assembly of the control rod 62.

[0131] One end of the control rod 62 is movably connected to a limiting mechanism 63. The limiting mechanism 63 includes a clamping plate 631 fixed to one end of the sleeve rod 622. A rotating wheel 632 is rotatably connected inside the clamping plate 631. The rotating wheel 632 is attached to the side of the lower mold 4 and the upper mold 5.

[0132] More specifically, the control rod 62 provides support and adaptive telescopic adjustment for the limiting mechanism 63. Through the rotating wheel 632, it fits against the side of the corresponding lower mold 4 or upper mold 5. Based on the depth of the contour when the template is displaced, and with the cooperation of the thrust spring 624, the position of the limiting mechanism 63 is adaptively adjusted.

[0133] It should be further explained that by setting the limiting mechanism 63 in the two sets of limiting parts 6 opposite to each other and attaching it to both sides of the template, the spacing between them is adaptively adjusted according to the depth of the template outline, so as to dynamically limit the amplitude of the swing of the adhesive part 8 at different positions between the two templates.

[0134] Furthermore, a telescopic rod 633 is fixed between the clamping plates 631 in the lower frame 1 and the upper frame 2.

[0135] More specifically, both ends of the telescopic rod 633 have retractable output ends, which are fixed between the opposing clamping plates 631 in the lower frame 1 and the upper frame 2 respectively. When the platform plates 22 in the two frames move towards the center at the same time, the output ends at both ends retract into the telescopic rod 633.

[0136] It should be further explained that when the two platform plates 22 move to their limit towards the center, they can fully press the two templates against the sole and upper of the shoe, while at the same time the output ends of the telescopic rod 633 are completely retracted inside.

[0137] Furthermore, an adjustment mechanism 25 is installed on the side of the platform plate 22. The adjustment mechanism 25 includes a stabilizing block 251 fixed to the side of the platform plate 22, and an adjustment rod 252 is rotatably connected to the stabilizing block 251. The adjustment rod 252 is threadedly connected to the connecting plate 61.

[0138] More specifically, both sides of one end of the platform plate 22 of the two frames are equipped with adjustment mechanisms 25, which are used to adjust the position of the corresponding limit member 6. It is necessary to ensure that the positions of the two sets of limit members 6 remain relative after adjustment, so as to effectively limit the distance of the adhesive application part 8 swinging to both sides.

[0139] It should be further explained that when the adhesive part 8 swings outward to its limit, it can fit against the side of the telescopic rod 633.

[0140] Example 4

[0141] Please see Figure 4 and Figures 9-12 As shown, the shoe sole and upper gluing device for footwear production proposed in this embodiment, based on embodiment two, further includes a transmission unit 72 comprising a movable rod 721 movably sleeved on the support plate 71 and the sleeve plate 712, an extension rod 722 movably sleeved at one end of the movable rod 721, and a fixing rod 725 threadedly connected to the side of the movable rod 721, with one end of the fixing rod 725 abutting against the side of the extension rod 722.

[0142] More specifically, the moving rod 721 extends laterally through the support plate 71 and the sleeve plate 712, so that the transmission unit 72 is positioned laterally at the center of the two frames. Under the drive, the transmission unit 72 realizes forward and backward reciprocating motion.

[0143] Furthermore, by rotating the fixing rod 725 clockwise or counterclockwise, the front end of the fixing rod 725 can be made to be close to or detach from the side of the extension rod 722. When it is close to the extension rod 722, the length of the transmission unit 72 after adjustment can be fixed. When it is detached, the length of the transmission unit 72 can be adjusted.

[0144] Furthermore, a toothed rod 723 is fixed to one end of the extension rod 722.

[0145] The swing mechanism 82 includes a mounting plate 821 fixed on the support rod 81, and rotating gears 822 are rotatably connected to both ends of the mounting plate 821. The rotating gears 822 mesh with the side of the rack 723.

[0146] More specifically, the rack 723 has tooth profiles on both sides and meshes with the corresponding rotating gear 822. When the transmission unit 72 reciprocates, the rack 723 moves back and forth between the two rotating gears 822, causing the two rotating gears 822 to rotate in opposite directions at the same time.

[0147] A swing rod 824 is movably connected to the rotating gear 822, and a torsion spring 823 is movably connected between the swing rod 824 and the rotating gear 822. At the same time, the swing rod 824 is attached to the side of the telescopic rod 633 at a set angle.

[0148] More specifically, swing rods 824 are installed at the top and bottom of the rotating gear 822. Each swing rod 824 is connected to the rotating gear 822 by a torsion spring 823. When the rotating gear 822 rotates, it drives the swing rods 824 to swing. When the front end of the swing rod 824 contacts the outer telescopic rod 633, the torsion spring 823 twists in the opposite direction, causing the swing rod 824 to stop swinging outward. When the swing rod 824 swings inward, the torsion force of the torsion spring 823 pushes the swing rod 824 back to its original position.

[0149] Furthermore, a glue gun 83 is fixed to one end of the swing rod 824, and an interface 831 is provided on the side of the glue gun 83.

[0150] More specifically, each swing rod 824 has a glue gun 83 fixed at its front end, such that the glue outlets of at least two glue guns 83 face upwards and the glue outlets of two glue guns 83 face downwards, with the glue outlets parallel to the contact surface of the template in the corresponding direction. Thus, when the template moves toward the glue gun 83, the glue outlets of the glue gun 83 can stably apply glue to the corresponding sole or upper.

[0151] It should be further explained that the distance between the glue gun 83 and the template can be adjusted by adjusting the depth of the connection between the screw 53 on the back of the template and the screw hole 241, so that the glue gun 83 can be used stably with templates of different sizes.

[0152] Meanwhile, the glue gun 83 is connected to the hose of the external glue dispensing device through the side interface 831, and controls the glue dispensing device to operate synchronously with the drive motor 713, so that the glue gun 83 starts to dispense glue when the swing mechanism 82 swings.

[0153] Furthermore, the support rod 81 is composed of a connecting pipe 811 and a connecting rod 812. The connecting rod 812 is movably sleeved inside the connecting pipe 811. One end of the connecting pipe 811 is fixed on the support plate 71, and one end of the connecting rod 812 is fixed on the mounting plate 821.

[0154] More specifically, support rods 81 are installed on the support plate 71, and at the top and bottom of the transmission unit 72. Mounting plates 821 are fixed to the front ends of the connecting rods 812 of the two support rods 81. The two mounting plates 821 are located at the top and bottom of the two rotating gears 822 to ensure the stability of the rotation of the rotating gears 822 and their meshing with the rack 723.

[0155] The side of the connecting pipe 811 is threaded with a fixing screw 813, and one end of the fixing screw 813 is attached to the side of the connecting rod 812.

[0156] More specifically, by rotating the fixing screw 813 clockwise or counterclockwise, the front end of the fixing screw 813 can be made to be close to or detach from the side of the connecting rod 812. When it is close to the side, the length of the support rod 81 is fixed, while when it is detached, the length of the support rod 81 can be adjusted.

[0157] In addition, when the platform plates 22 in the two frames move closer to the center, so that the lower mold 4 and the upper mold 5 close to press the sole and upper of the shoe, the glued part 8 is attached to the opposite side of the two platform plates 22, thereby ensuring that the sole and upper are fully pressed together.

[0158] Furthermore, the rebound mechanism 75 consists of a limiting ring 751 and a tension spring 752. The limiting ring 751 is fixed to one end of the moving rod 721, and the tension spring 752 is movably sleeved on the side of the moving rod 721. At the same time, the two ends of the tension spring 752 are attached between the limiting ring 751 and the support plate 71.

[0159] More specifically, when the moving rod 721 moves forward to its limit under the force of the meshing rotation of the transmission gear 741 and the transmission groove 724, the missing tooth of the transmission gear 741 corresponds to the tooth profile in the transmission groove 724. At this time, under the push of the tension spring 752, the moving rod 721 drives the entire transmission unit 72 to move backward and return to the initial position. The tooth profile of the transmission gear 741 re-meets and rotates with the tooth profile in the transmission groove 724, realizing the reciprocating motion of the entire transmission unit 72.

[0160] Example 5

[0161] Please see Figure 4 and Figures 9-13 As shown, the shoe sole and upper gluing device for footwear production proposed in this embodiment, based on embodiment two, further includes a transmission unit 2 73, which includes a rotating knob 731 rotatably connected to one end of the support plate 71, a synchronous gear 732 fixed to one end of the rotating knob 731, a connecting rod 734 fixed to one end of the synchronous gear 732, and an insertion rod 735 provided at one end of the connecting rod 734.

[0162] The transmission unit 2 73 also includes a screw rod 736 threadedly connected to the movable block 24, with a plug block 737 fixed at one end of the screw rod 736, and one end of the plug rod 735 plugged into the plug block 737.

[0163] More specifically, the transmission unit 73 adopts a separable design. It is inserted into the insertion block 737 through the insertion rod 735. When the synchronous gear 732 rotates, it drives the screw rod 736 to rotate at the same time. Under the force of the screw rod 736 and the internal thread connection of the moving block 24, the moving block 24 drives the corresponding template to produce displacement changes.

[0164] It should be further explained that the side of the plug block 737 has a round hole, and the plug rod 735 and the screw rod 736 are set at right angles and perpendicular to each other. So when the round hole and the plug rod 735 are vertically opposite each other, the output end of the hydraulic rod 23 drives the platform plate 22 to achieve a change in height, so that the plug rod 735 can be inserted into or disengaged from the round hole opened in the plug block 737.

[0165] When the synchronous gear 732 stops rotating, the round hole of the plug block 737 and the plug rod 735 are vertically opposite each other, and after disengagement, the plug block 737 and the screw rod 736 remain vertical, making it easy to reconnect.

[0166] Furthermore, the synchronous gears 732 in the transmission units 73 at both ends of the support plate 71 are meshed with synchronous toothed belts 733.

[0167] More specifically, when any one of the synchronous gears 732 rotates, it drives the other synchronous gear 732 to rotate simultaneously through the synchronous toothed belt 733, thereby realizing the turntable with synchronous rotation of the double helical rods 736, so that the two templates can move in the same direction at the same time.

[0168] Furthermore, the transmission mechanism 74 includes a transmission gear 741 fixed on the output end of the drive motor 713, and a transmission groove 724 is provided on the side of the moving rod 721, in which the transmission gear 741 meshes.

[0169] More specifically, the output end of the drive motor 713 has a bidirectional rotation function, and the transmission gear 741 is a toothed gear. The bottom of the transmission groove 724 is provided with a tooth profile. During operation, the output end drives the transmission gear 741 to rotate. Under the action of the meshing force between the transmission gear 741 and the tooth profile in the transmission groove 724, the moving rod 721 drives the transmission unit 72 to move forward as a whole.

[0170] Furthermore, the transmission mechanism 74 also includes a drive gear 742 fixed to one end of the transmission gear 741, a connecting toothed belt 743 meshing on the side of the drive gear 742, a rotating gear 744 meshing inside the connecting toothed belt 743, a bevel gear 745 fixed to one end of the rotating gear 744, a bevel gear 746 meshing on the side of the bevel gear 745, and a rotating knob 731 fixed to one end of the bevel gear 746.

[0171] More specifically, as the transmission gear 741 rotates, it drives the drive gear 742 to rotate. At this time, the connecting belt 743 drives the rotating gear 744 to rotate simultaneously, so that the first bevel gear 745 and the second bevel gear 746 mesh and rotate, thereby causing the rotary knob 731 to drive the synchronous gear 732 to rotate, achieving the effect of rotating the screw rod 736.

[0172] Furthermore, a positioning plate 748 is rotatably connected to one end of the drive gear 742 and the rotating gear 744.

[0173] More specifically, the drive gear 742 and the rotating gear 744 are fixed at both ends of the positioning plate 748 to improve the stability of gear rotation and prevent the gear from detaching from the toothed belt.

[0174] Furthermore, the sides of bevel gear 1 745 and bevel gear 2 746 are rotatably connected to a stabilizing plate 747.

[0175] More specifically, the stabilizing plate 747 is right-angled, and bevel gear one 745 and bevel gear two 746 are fixed at both ends of the stabilizing plate 747 respectively, thereby improving the stability of the meshing of the two bevel gears.

[0176] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
