Description

Technical Field

[0001] The present invention relates to the technical field of footwear production, and particularly to an adhesive application device for the soles and uppers of footwear production. Background Art

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

[0003] Currently, although the existing adhesive application equipment for soles and uppers has improved the operation efficiency to a certain extent, there are still significant technical bottlenecks. For example, most equipment adopts a fixed adhesive application path design and cannot adaptively adjust the width of the adhesive line according to the changes in the side profiles of the soles and uppers, resulting in uneven adhesive application paths and adhesive overflow during crimping. Although some equipment has introduced a hydraulic pressing function, the adhesive application and pressing processes are often separated and need to be disassembled and assembled in multiple steps at different workstations to complete the crimping, which prolongs the production cycle and is likely to cause deviations in the crimping of the sole and the upper, affecting the bonding accuracy.

[0004] In summary, there is an urgent need to develop an adhesive application device for the soles and uppers of footwear that integrates adaptive dynamic adhesive application and high-stability pressing functions to break through the existing technical bottlenecks and improve the uniformity and stability of the adhesive application process and production efficiency in footwear production. Summary of the Invention

[0005] (1) Technical Problems to be Solved

[0006] In view of the deficiencies of the prior art, the present invention provides an adhesive application device for the soles and uppers of footwear production, which has the advantages of being able to adaptively and dynamically adjust the width of the adhesive line for adhesive application and the pressing stability of the soles and uppers, improving the uniformity of adhesive application and the pressing accuracy of footwear, and further improving the production quality and efficiency. It solves the problems that the width of the adhesive line cannot be adaptively adjusted according to the shoe type at the present stage, resulting in uneven adhesive application and adhesive overflow during crimping, and the problem of crimping deviation in the separate pressing process using multiple workstations for cooperation.

[0007] (2) Technical Solutions

[0008] To achieve the above object, the present invention provides the following technical solution: An adhesive application device for the soles and uppers of footwear production, comprising a lower frame, an upper frame, a support rod, a lower mold, an upper mold, a limiting member, a driving member, and an adhesive application member. The lower frame and the upper frame are arranged vertically opposite to each other, and a support rod is installed between them. The upper frame is located at the top of the lower frame and has the same structure.

[0009] Both the lower frame and the upper frame are composed of a supporting plate and a platform plate. Hydraulic rods are fixed between the supporting plate and the platform plate. Hydraulic rods are installed at the four corner positions of the supporting plate, and the output ends of the hydraulic rods are fixed at the corresponding positions of the platform plate. The hydraulic rods operate synchronously, enabling the platform plate to smoothly achieve height displacement changes for adjusting the distance between the platform plates in the two frames (the lower frame and the upper frame).

[0010] At the same time, there are specifically four support rods, which are respectively fixed at the four corner positions of the supporting plates in the two frames to connect the two frames and simultaneously play a supporting role for the upper frame.

[0011] A lower mold and an upper mold are respectively movably connected to the platform plates in the lower frame and the upper frame, and the lower mold and the upper mold are arranged opposite to each other. The lower mold is installed above the lower frame, and the upper mold is installed below the upper frame. The lower mold is used for sleeving the inclined surface, and the upper mold is used for fixing the shoe sole.

[0012] There are two groups of limit members for restricting the swing distance between the lower frame and the upper frame. The limit members are attached to the sides of the lower mold and the upper mold. The two groups of limit members are arranged opposite to each other. One group is attached to the outer sides of the lower mold and the upper mold, and the other group is attached to the inner sides of the lower mold and the upper mold. The two groups of limit members automatically adjust the distance between the two groups of limit members according to the depth changes of the side profiles when the two templates (the lower mold and the upper mold) are displaced simultaneously, enabling the glue application member to automatically adjust the width of the applied glue according to the changes of the side profiles of the two templates.

[0013] A driving member is movably connected to one end of the lower frame and the upper frame. The driving member is composed of a support plate, a first transmission unit, a second transmission unit, a transmission mechanism, and a spring-back mechanism. The middle of the support plate is movably connected to the first transmission unit, and a spring-back mechanism is movably connected to the first transmission unit. Both ends of the support plate are movably connected to the second transmission unit. The two second transmission units are respectively connected to the lower mold and the upper mold. The first transmission unit drives the glue application member to swing through displacement changes to achieve swing-type glue application operation on the opposite surfaces of the shoe sole and the shoe upper. The second transmission unit drives the two connected templates to move synchronously through rotational force.

[0014] When the first transmission unit is displaced to a specified position, under the action of the spring-back mechanism, the first transmission unit returns to the initial position, and through reciprocating operation, the swing operation of the glue application member is achieved.

[0015] A transmission mechanism is movably connected between the first transmission unit and the second transmission unit. The transmission mechanism is used to drive the two transmission units (the first transmission unit and the second transmission unit) to operate synchronously, enabling the glue application member to swing between the two templates while the two templates generate displacement changes to achieve overall glue application operation on the opposite surfaces of the shoe sole and the shoe upper.

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

[0017] An upper gluing member is movably connected between the lower frame and the upper frame. The upper gluing member is composed of a support rod, a swing mechanism and a glue gun. One end of the support rod is fixed on the support plate, and a swing mechanism is fixed at the other end. The first 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 upper gluing member is stably located between the lower frame and the upper frame. The glue gun is driven to swing by the swing mechanism to realize the glue application operation on the sole and the upper.

[0018] As a further improvement of the above solution, a limit chute is opened on the platform plate, a moving block is slidably connected in the limit chute, a screw hole is opened on the moving block, and at the same time, screws are fixedly arranged at the bottoms of the lower mold and the upper mold, and one end of the screw is threadedly connected in the screw hole.

[0019] Through the above technical solution, the limit chute is located at the middle position of the platform plate and is arranged along the length direction of the platform plate. The moving block slides in the limit chute, thereby driving the corresponding connected lower mold or upper mold to achieve displacement movement.

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

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

[0022] As a further improvement of the above solution, an air inflation bag is fixed on the lower mold, and at the same time, an air valve is arranged on the side of the lower mold, and the air valve is communicated with the air inflation bag.

[0023] Through the above technical solution, the air inflation bag is designed according to the shape of the sole. When the upper is sleeved on the lower mold, the air inflation bag fully adheres to the bottom of the upper, thereby ensuring the stability during glue application and bonding. And the air inflation bag is inflated through the air valve to make it expand, which is convenient for air supplement and deflation adjustment during use and convenient for storage later.

[0024] As a further improvement of the above solution, an installation groove is opened at the bottom of the upper mold, and at the same time, a spring button is arranged on the side of the upper mold, and one end of the spring button penetrates into the installation groove.

[0025] Through the above technical solution, the installation groove matches the size of the sole of the international standard code number. By placing the sole in the installation groove and under the acting force of the output end of the spring button pushing outward, it is clamped on both sides of the sole, realizing the function of fixing the sole in the installation groove.

[0026] As a further improvement of the above solution, a regulation sliding groove is provided on the side of the platform plate. The limiting member is composed of two connecting plates, which are respectively movably connected to the side of the platform plate in the lower frame and the upper frame.

[0027] One end of the connecting plate is fixed with a regulation sliding block, and the regulation sliding block is slidably connected in the regulation sliding groove

[0028] Through the above technical solution, regulation sliding grooves are relatively provided on both sides of one end of the platform plate in the two frames, and each set of limiting members 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. And the regulation sliding blocks installed on the side are slidably connected in the corresponding regulation sliding grooves. When the limiting member moves as a whole, the regulation sliding blocks slide in the regulation sliding grooves, improving the stability of the displacement of the limiting member.

[0029] As a further improvement of the above solution, the other end of the connecting plate is movably connected with a regulation rod. The regulation rod is composed of a sleeve, a sleeve rod and a mounting rod. One end of the sleeve is movably sleeved in the connecting plate, one end of the sleeve rod is movably sleeved in the sleeve, and the other end is fixed on the mounting rod. At the same time, a thrust spring is movably sleeved on the side of the sleeve rod, and both ends of the thrust spring are attached between the sleeve and the mounting rod.

[0030] Through the above technical solution, when the front end of the mounting rod is stressed, the thrust spring is tightened, and at the same time the sleeve rod contracts into the sleeve. When the front end of the mounting rod is not stressed, under the tension of the thrust spring, the mounting rod is pushed forward, so that the overall length of the regulation rod can be adaptively contracted and adjusted according to the stress magnitude at the front end of the mounting rod.

[0031] As a further improvement of 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 regulation rod. By rotating the positioning rod forward and backward, the front end of the positioning rod is closely attached to or separated from the side of the sleeve, facilitating the disassembly and assembly operations of the regulation rod.

[0033] As a further improvement of the above solution, a limiting mechanism is movably connected to one end of the regulation rod. The limiting mechanism includes a clamping plate fixed to one end of the sleeve rod, and a rotating wheel is rotatably connected in the clamping plate, and the rotating wheel is attached to the sides of the lower die and the upper die.

[0034] Through the above technical solution, the control rod plays a role in supporting the limiting mechanism and adaptively adjusting the position in terms of telescopic length. By fitting the rotating wheel to the side of the corresponding lower die or upper die, and according to the depth of the contour when the template is displaced, and with the cooperation of the thrust spring, the position of the limiting mechanism is adaptively adjusted. <> <>

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

[0036] Through the above technical solution, both ends of the telescopic rod have telescopic output ends, which are respectively fixed between the opposite clamping plates in the lower frame and the upper frame. When the platform plates in the two frames move towards the middle position simultaneously, the output ends at both ends contract into the telescopic rod. <> <>

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

[0038] Through the above technical solution, adjusting mechanisms are installed on both sides at one end of the platform plates of the two frames to adjust the positions of the corresponding limit members. It is necessary to ensure that the positions of the two groups of limit members remain relative after adjustment, so as to effectively limit the swing distance of the gluing member to both sides. <> <>

[0039] As a further improvement of the above solution, the first transmission unit includes a moving rod movably sleeved on the support plate and the sleeve plate. An extension rod is movably sleeved at one end of the moving rod. At the same time, a fixed rod is threadedly connected to the side of the moving rod, and one end of the fixed rod fits against the side of the extension rod. <> <>

[0040] Through the above technical solution, the moving rod horizontally penetrates through the support plate and the sleeve plate, so that the first transmission unit is horizontally located at the central position between the two frames as a whole. Under the drive of the first transmission unit, a reciprocating displacement movement in the front and back directions is realized. <> <>

[0041] As a further improvement of the above solution, a toothed rod is fixed at one end of the extension rod. The swinging mechanism includes a mounting plate fixed on the support rod. Rotating gears are rotatably connected to both ends of the mounting plate, and the rotating gears are engaged with the side of the toothed rod. <> <>

[0042] Through the above technical solution, tooth profiles are provided on both sides of the toothed rod and are engaged with the corresponding rotating gears on the side. When the first transmission unit reciprocates, the toothed rod moves back and forth between the two rotating gears, causing the two rotating gears to rotate in opposite directions simultaneously. <> <>

[0043] As a further improvement of the above solution, a swinging rod is movably connected to the rotating gear. A torsion spring is movably connected between the swinging rod and the rotating gear. At the same time, the swinging rod fits against the side of the telescopic rod at a set angle. <> <>

[0044] Through the above technical solution, swing rods are installed at both the top and bottom of the rotating gear, and a torsion spring is installed between each swing rod and the rotating gear. 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 reverse direction, causing the swing rod to stop swinging outward. When the swing rod swings inward, it is also pushed back to its original position by the torque of the torsion spring.

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

[0046] Through the above technical solution, a glue gun is fixed at the front end of each swing rod, so that at least two glue guns have their glue outlets facing upward and two glue guns have their glue outlets facing downward. 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 outlets of the glue guns can stably apply glue to the corresponding sole or shoe upper.

[0047] As a further improvement of the above solution, the support rod is composed 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 on the support plate, and one end of the connecting rod is fixed on the mounting plate.

[0048] Through the above technical solution, support rods are installed on the support plate at both the top and bottom of the first transmission unit. The front ends of the connecting rods in the two support rods are fixedly provided with mounting plates on the opposite surfaces. The two mounting plates are located at the top and bottom of the two rotating gears, ensuring the stability of the rotation of the rotating gears and their meshing with the toothed rod.

[0049] As a further improvement of the above solution, a fixing screw is threadedly connected to the side of the connecting pipe, and one end of the fixing screw is in contact with the side of the connecting rod.

[0050] Through the above technical solution, by rotating the fixing screw clockwise and counterclockwise, the front end of the fixing screw is pressed against or separated from the side of the connecting rod. When pressed against, the length of the support rod is fixed, and when separated, the length of the support rod can be adjusted.

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

[0052] The second transmission unit further includes a screw rod threadedly connected to the moving block. A plugging block is fixed at one end of the screw rod, and one end of the plug rod is plugged into the plugging block.

[0053] Through the above technical solution, the second transmission unit adopts a separable design. The insertion rod is inserted into the insertion block. When the synchronous gear rotates, it drives the screw rod to rotate simultaneously. Under the acting force of the threaded connection between the screw rod and the moving block, the moving block drives the corresponding template to generate a displacement change.

[0054] As a further improvement of the above solution, a synchronous toothed belt is engaged between the synchronous gears in the second transmission units at both ends of the support plate.

[0055] Through 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 a turntable with synchronous rotation of the double screw rods, and achieving the effect that the two templates are displaced in the same direction simultaneously.

[0056] As a further improvement of the above solution, the transmission mechanism includes a transmission gear fixed on the output end of the driving motor. At the same time, a transmission groove is provided on the side of the moving rod, and the transmission gear is engaged in the transmission groove.

[0057] Through the above technical solution, the output end of the driving motor has the function of bidirectional rotation. At the same time, the transmission gear is a toothless gear, and a tooth profile is provided at the bottom of the transmission groove. During operation, the output end drives the transmission gear to rotate. Under the acting force of the engagement between the transmission gear and the tooth profile in the transmission groove, the moving rod drives the first transmission unit to move forward as a whole.

[0058] As a further improvement of the above solution, the transmission mechanism further includes a driving gear fixed at one end of the transmission gear. A linkage toothed belt is engaged on the side of the driving gear. A rotating gear is engaged in the linkage toothed belt. A first bevel gear is fixed at one end of the rotating gear. A second bevel gear is engaged on the side of the first bevel gear. One end of the second bevel gear is fixed on the rotating knob.

[0059] Through the above technical solution, when the transmission gear rotates, it drives the driving gear to rotate at the same time. At this time, the rotating gear is driven to rotate simultaneously by the linkage toothed belt, so that the first bevel gear and the second bevel gear are engaged and rotated, thereby driving the synchronous gear to rotate by the rotating knob, and realizing the effect of the screw rod rotating.

[0060] As a further improvement of the above solution, a positioning plate is rotatably connected to one ends of the driving gear and the rotating gear.

[0061] Through the above technical solution, the driving gear and the rotating gear are respectively fixed at both ends of the positioning plate, improving the stability of the gear rotation and preventing the gear from disengaging from the toothed belt.

[0062] As a further improvement of the above solution, a stabilizing plate is rotatably connected to the sides of the first bevel gear and the second bevel gear.

[0063] Through the above technical solution, the stabilizing plate is in a right-angle shape, and the bevel gear one and the bevel gear two are respectively fixed at the two ends of the stabilizing plate, so that the meshing stability of the two bevel gears is improved by the stabilizing plate.

[0064] As a further improvement of the above scheme, the rebound mechanism consists of a limiting ring and a tension spring. The limiting ring is fixed at 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 fitted between the limiting ring and the support plate.

[0065] Through the above technical solution, when the moving rod moves forward to the limit under the force of the transmission gear engaging and rotating with the transmission groove, the missing teeth of the transmission gear correspond to the tooth profile in the transmission groove. At this time, under the push of the tension spring, the moving rod drives the transmission unit to move backward as a whole and return to the initial position, and the tooth profile of the transmission gear engages and rotates with the tooth profile in the transmission groove again, realizing the reciprocating motion of the transmission unit as a whole.

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

[0067] 1. The sole and upper gluing device for shoe production is designed according to the shape of the sole through a template. When the template moves, the limiter adaptively adjusts the swing spacing of the gluing component according to the depth of the contour of the side of the template in contact. With the help of the torsion spring installed on the swing arm, the width of the glue line is dynamically controlled when gluing the sole and upper, effectively improving the uniformity and stability of gluing, avoiding glue overflow due to uneven glue during crimping, and avoiding excessive glue waste.

[0068] 2. The sole and upper gluing device for shoe production completes the gluing operation of the sole and upper through the synchronous operation of the two templates and the cooperation of the gluing device. After the two templates are in the initial position and separated from the front end of the gluing part, the hydraulic rods in the two frames can be controlled to operate and close the platform plates, thereby directly crimping the sole and upper without changing the work station, further improving the crimping accuracy of the sole and upper, while effectively shortening the space occupied and production cycle of traditional step-by-step crimping equipment, and reducing equipment investment costs.

[0069] 3. The sole and upper gluing device for shoe production uses a driving motor as a power source and is connected to a transmission mechanism to drive transmission unit 1 and transmission unit 2 to operate simultaneously. This allows the upper gluing part to be swung and glued while the lower mold and upper mold are displaced synchronously, achieving a single power source dual-drive effect. At the same time, it effectively improves the consistency and stability of the operation of various functional equipment during equipment operation.

[0070] 4. The glue - applying device for the soles and uppers of shoes in shoe production realizes quick disassembly, assembly and height adjustment with the moving block through the threaded connection between the lower die and the upper die. This is convenient for replacing templates of different sizes and contours for later use, thus effectively improving the flexibility and diversity of the device.

[0071] 5. The glue - applying device for the soles and uppers of shoes in shoe production can, when replacing templates of different sizes, adjust the positions of the first transmission unit, the support rod and the limiting part, so that each functional part can fully adapt to templates of different sizes for use, further improving the flexibility of the equipment.

[0094] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0095] Example 1

[0096] Please refer to Figures 1-13 As shown, a glue - applying device for shoe soles and uppers in shoe production proposed in this embodiment includes a lower frame 1, an upper frame 2, a support rod 3, a lower mold 4, an upper mold 5, a limiting member 6, a driving member 7, and a glue - applying member 8. The lower frame 1 and the upper frame 2 are vertically arranged opposite to each other, and a support rod 3 is installed between them. The upper frame 2 is located at the 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 supporting plate 21 and a platform plate 22. A hydraulic rod 23 is fixed between the supporting plate 21 and the platform plate 22. The hydraulic rods 23 are installed at the four corner positions of the supporting plate 21. The output ends of the hydraulic rods 23 are fixed at the corresponding positions of the platform plate 22, and the hydraulic rods 23 operate synchronously, enabling the platform plate 22 to smoothly achieve height displacement changes for adjusting the distance between the platform plates 22 in the two frames (the lower frame 1 and the upper frame 2).

[0098] At the same time, the support rod 3 is specifically four in number, and is respectively fixed at the four corner positions of the supporting plates 21 in the two frames, realizing the connection of the two frames and simultaneously playing a supporting role for the upper frame 2.

[0099] The lower mold 4 and the upper mold 5 are respectively movably connected to the platform plates 22 in the lower frame 1 and the upper frame 2, 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 for sleeving the inclined surface, and the upper mold 5 is used for fixing the shoe sole.

[0100] It should be further noted that the sizes of the lower mold 4 and the upper mold 5 are matched and the positions are corresponding, and they can move horizontally at the same time. When contacting the glue - applying member 8, it realizes the glue - applying operation on the opposite surfaces of the upper shoe and the sole.

[0101] There are two groups of limiting members 6 provided between the lower frame 1 and the upper frame 2 for limiting the swing distance. The limiting members 6 are attached to the sides of the lower mold 4 and the upper mold 5. The two groups of limiting members 6 are arranged opposite to each other. One group is attached to the outer sides of the lower mold 4 and the upper mold 5, and the other group is attached to the inner sides of the lower mold 4 and the upper mold 5. The two groups of limiting members 6 automatically adjust the distance between the two groups of limiting members 6 according to the depth change of the side profiles when the two templates (the lower mold 4 and the upper mold 5) move simultaneously, so that the glue - applying member 8 automatically adjusts the width of the applied glue according to the changes of the side profiles of the two templates.

[0102] One end of the lower frame 1 and the upper frame 2 is movably connected with a driving member 7. The driving member 7 is composed of a support plate 71, a first transmission unit 72, a second transmission unit 73, a transmission mechanism 74 and a spring-back mechanism 75. The middle of the support plate 71 is movably connected with the first transmission unit 72. The spring-back mechanism 75 is movably connected to the first transmission unit 72. Both ends of the support plate 71 are movably connected with the second transmission unit 73. The two second transmission units 73 are respectively connected to the lower die 4 and the upper die 5. The first transmission unit 72 drives the glue application member 8 to swing through displacement change, so as to realize the swing-type glue application operation on the opposite surfaces of the sole and the shoe upper. The second transmission unit 73 drives the synchronous displacement of the two connected templates through rotational force.

[0103] When the first transmission unit 72 is displaced to the specified position, under the action of the spring-back mechanism 75, the first transmission unit 72 returns to the initial position. Through reciprocating operation, the swinging operation of the glue application member 8 is realized.

[0104] A transmission mechanism 74 is movably connected between the first transmission unit 72 and the second transmission unit 73. The transmission mechanism 74 is used to drive the two transmission units (the first transmission unit 72 and the second transmission unit 73) to operate synchronously, so that while the glue application member 8 swings between the two templates, the two templates generate displacement changes, realizing the overall glue application operation on the opposite surfaces of the sole and the shoe upper.

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

[0106] A glue application member 8 is movably connected between the lower frame 1 and the upper frame 2. The glue application member 8 is composed of a support rod 81, a swinging mechanism 82 and a glue gun 83. One end of the support rod 81 is fixed on the support plate 71, and the other end is fixed with the swinging mechanism 82. The first transmission unit 72 is connected to the swinging mechanism 82. A glue gun 83 is movably connected to the swinging mechanism 82. The glue gun 83 is located between the lower die 4 and the upper die 5. The support rod 81 is used to support the swinging mechanism 82 and the glue gun 83, so that the glue application member 8 is stably located between the lower frame 1 and the upper frame 2. By driving the glue gun 83 to swing through the swinging mechanism 82, the glue application operation on the sole and the shoe upper is realized.

[0107] The working principle of the shoe sole and upper gluing device for shoe production proposed in this embodiment is as follows: During use, the upper is put on the lower mold 4, and then the sole is fixed in the upper mold 5, so that the bottom of the upper faces the bonding surface required by the sole. At this time, the driving motor 713 is controlled to operate, so that the transmission mechanism 74 drives the two transmission units to rotate synchronously, causing the two templates to gradually displace from the front end to the tail end. At the same time, the gluing member 8 completes the first gluing operation on the entire opposite surfaces of the sole and the upper in a swinging state. Then, the driving motor 713 is controlled to operate in the reverse direction, causing the two templates to gradually displace from the tail end to the front end. At the same time, the gluing member 8 completes the second gluing operation on the entire opposite surfaces of the sole and the upper in a swinging state. After the second gluing operation is completed, the two templates are in the initial position and completely separate from the front end of the gluing member 8. Then, the output end of the hydraulic rod 23 is controlled to extend outward, causing the platform plates 22 in the two frames to drive the two templates to approach the middle, pressing the opposite surfaces of the sole and the upper tightly for bonding and forming. Before demolding, first remove the upper from the lower mold 4, and then control the output end of the hydraulic rod 23 to contract inward, causing the formed shoe body to rise to the initial position with the upper mold 5, and then separate the sole from the upper mold 5, so that the shoe body can be taken off.

[0108] Furthermore, a limit sliding groove 221 is formed on the platform plate 22. A moving block 24 is slidably connected in the limit sliding groove 221. A threaded hole 241 is formed in the moving block 24. At the same time, screw rods 53 are fixedly arranged at the bottoms of the lower mold 4 and the upper mold 5. One end of the screw rod 53 is threadedly connected in the threaded hole 241.

[0109] More specifically, the limit sliding groove 221 is located at the middle position of the platform plate 22 and is arranged along the length direction of the platform plate 22. The moving block 24 slides in the limit sliding groove 221, thereby driving the corresponding connected lower mold 4 or upper mold 5 to achieve displacement movement.

[0110] It should be further noted that the width of the moving block 24 matches the width in the limit sliding groove 221, improving the sliding stability of the moving block 24. The lower mold 4 and the upper mold 5 are threadedly connected to the threaded hole 241 through the screw rods 53 provided at one end of the back surface, realizing the connection with the moving block 24. Thus, when the moving block 24 slides, it drives the corresponding template to achieve displacement movement.

[0111] Moreover, the way of threadedly connecting the screw rod 53 and the threaded hole 241 can not only improve the connection stability between the template and the moving block 24, but also facilitate the replacement of templates with different sizes for use in the later stage.

[0112] Embodiment Two

[0113] Please refer to Figure 3 and Figures 5-6As shown in the figure, for the sole and upper gluing device used in shoe production in this embodiment, on the basis of Embodiment 1, this embodiment further includes that stable rollers 222 are rotatably connected to both ends of the platform plate 22, and the stable rollers 222 are attached to the opposite surfaces of the lower mold 4 and the upper mold 5.

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

[0115] Furthermore, an air inflation bag 41 is fixed on the lower mold 4, and at the same time, an air valve 42 is provided on the side of the lower mold 4, and the air valve 42 is communicated with the air inflation bag 41.

[0116] More specifically, the air inflation bag 41 is designed according to the shape of the sole. When the upper is sleeved on the lower mold 4, the air inflation bag 41 fully adheres to the bottom of the upper, so as to ensure the stability during glue application and bonding. And by means of the air valve 42, air is inflated into the air inflation bag 41 to make it expand, which is convenient for air replenishment and deflation adjustment during use and for storage later.

[0117] It should be further noted that an air inflation bag 41 with a matching size and inflation size is provided on each lower mold 4, and the size of the lower mold 4 is designed according to the same international standard size. Thus, when replacing the lower mold 4 of different sizes, the corresponding air inflation bag 41 above can fully adhere to the inside of the upper of the same size, and different sizes of upper processing operations can be satisfied through replacement.

[0118] Furthermore, an installation groove 51 is opened at the bottom of the upper mold 5, and at the same time, a spring button 52 is provided on the side of the upper mold 5, and one end of the spring button 52 penetrates into the installation groove 51.

[0119] More specifically, the installation groove 51 coincides with the size of the sole of the international standard size. By placing the sole in the installation groove 51, under the acting force of the output end of the spring button 52 pushing outwards, it is clamped on both sides of the sole to realize the function of fixing the sole in the installation 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 fixing force and position of the sole, and there is no restriction here. And 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 penetrates into the installation groove 51. By installing a spring between the cylinder and the fixing button, under the push of the spring, the front end of the fixing button is closely attached to the side of the sole to realize the fixing of the sole.

[0121] And when replacing the lower mold 4, it is also necessary to replace the upper mold 5 of the same size to ensure the full bonding of the upper and sole of the same size.

[0122] In addition, the contours of the lower die 4 and the upper die 5 match the side contour of the sole to be crimped. The contours of the two templates are 0.4 cm - 1 cm wider than the contour of the sole, and the templates do not limit the use of glue for any type of footwear. For example, sports shoes, dress shoes, and casual shoes can all be used, and no specific limitations are made here.

[0123] Embodiment III

[0124] Please refer to Figures 2-7 As shown, for the shoe sole and shoe upper gluing device for shoe production proposed in this embodiment, on the basis of Embodiment II, this embodiment further includes that a regulation sliding groove 223 is provided on the side of the platform plate 22. The limiting member 6 is composed of two connecting plates 61, which are respectively movably connected to the side of the platform plate 22 in the lower frame 1 and the upper frame 2.

[0125] One end of the connecting plate 61 is fixed with a regulation sliding block 611, and the regulation sliding block 611 is slidably connected in the regulation sliding groove 223.

[0126] More specifically, regulation sliding grooves 223 are relatively provided on both sides at one end of the platform plate 22 in the two frames, 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 regulation sliding blocks 611 installed on the side are slidably connected in the corresponding regulation sliding grooves 223. When the limiting member 6 moves as a whole, the regulation sliding blocks 611 slide in the regulation sliding grooves 223, improving the stability of the displacement of the limiting member 6.

[0127] Further, the other end of the connecting plate 61 is movably connected with a regulation rod 62. The regulation rod 62 is composed 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 in 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 both 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 stressed, the thrust spring 624 is tightened, and at the same time, the sleeve rod 622 contracts into the sleeve 621. When the front end of the mounting rod 623 is not stressed, under the tension of the thrust spring 624, the mounting rod 623 is pushed forward, so that the overall length of the regulation rod 62 can be adaptively contracted and adjusted according to the stress magnitude at the front end of the mounting rod 623.

[0129] Further, 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 regulation rod 62. By rotating the positioning rod 612 clockwise and counterclockwise, the front end of the positioning rod 612 is made to closely adhere to or disengage from the side of the sleeve 621, facilitating the disassembly and assembly operations of the regulation rod 62.

[0131] One end of the regulation rod 62 is movably connected with 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 within the clamping plate 631, and the rotating wheel 632 is in contact with the sides of the lower die 4 and the upper die 5.

[0132] More specifically, the regulation rod 62 plays a role in supporting the limiting mechanism 63 and adaptively adjusting the position in a telescopic manner. By having the rotating wheel 632 in contact with the corresponding side of the lower die 4 or the upper die 5, and in conjunction with the thrust spring 624, the position of the limiting mechanism 63 is adaptively adjusted according to the depth of the contour when the template is displaced.

[0133] It should be further noted that the limiting mechanisms 63 in the two sets of limit members 6 are arranged oppositely and are in contact with both sides of the template. As the depth of the template contour changes, the distance between them is adaptively adjusted, thereby dynamically limiting the swing amplitude of the gluing member 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 telescopic output ends, which are respectively fixed between the opposite clamping plates 631 in the lower frame 1 and the upper frame 2. When the platform plates 22 in the two frames move towards the middle simultaneously, the output ends at both ends contract into the telescopic rod 633.

[0136] It should be further noted that when the two platform plates 22 move towards the middle to the limit, the two templates can fully press the sole and the shoe upper tightly. At the same time, the output ends at both ends of the telescopic rod 633 are completely retracted inside.

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

[0138] More specifically, adjusting mechanisms 25 are installed on both sides at one end of the platform plates 22 of the two frames, for adjusting the positions of the corresponding limit members 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 gluing member 8 swinging towards both sides.

[0139] It should be further noted that when the gluing member 8 swings outwards to the limit, it can be in contact with the side of the telescopic rod 633.

[0140] Example 4

[0141] Please refer to Figure 4 and Figures 9-12 As shown, based on the glue - applying device for the sole and upper of footwear production in Example 2, the glue - applying device in this example further includes that the first transmission unit 72 includes a moving rod 721 movably sleeved on the support plate 71 and the sleeve plate 712. One end of the moving rod 721 is movably sleeved with an extension rod 722. At the same time, a fixing rod 725 is threadedly connected to the side of the moving rod 721, and one end of the fixing rod 725 is attached to the side of the extension rod 722.

[0142] More specifically, the moving rod 721 horizontally penetrates through the support plate 71 and the sleeve plate 712, so that the first transmission unit 72 is horizontally located at the center position between the two frames. Driven, the first transmission unit 72 realizes reciprocating displacement motion back and forth.

[0143] And, by rotating the fixing rod 725 forward and backward, the front end of the fixing rod 725 is made to closely adhere to or separate from the side of the extension rod 722. When adhering, it realizes fixing the adjusted length of the first transmission unit 72, and when separating, it can adjust the length of the first transmission unit 72.

[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. Rotating gears 822 are rotatably connected to both ends of the mounting plate 821, and the rotating gears ⑧22 are engaged with the side of the toothed rod 723.

[0146] More specifically, tooth profiles are provided on both sides of the toothed rod 723 and are engaged with the corresponding rotating gears 822 on the corresponding sides. When the first transmission unit 72 reciprocates, the toothed rod 723 moves back and forth between the two rotating gears 822, causing the two rotating gears 822 to rotate in opposite directions simultaneously.

[0147] A swing rod 824 is movably connected to the rotating gear 822. 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. A torsion spring 823 is installed between each swing rod 824 and the rotating gear 822. When the rotating gear 822 rotates, it drives the swing rod 824 to achieve a swinging effect. When the front end of the swing rod 824 touches 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, it is also pushed by the torsion force of the torsion spring 823 to reset the swing rod 824.

[0149] Further, 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, a glue gun 83 is fixed to the front end of each swing rod 824, so that the glue outlets of at least two glue guns 83 face upward, and the glue outlets of the two glue guns 83 face downward. The glue outlets are parallel to the contact surfaces of the templates in the corresponding directions. Thus, when the template is displaced towards the glue gun 83, the glue outlets of the glue gun 83 can stably apply glue to the corresponding shoe sole or shoe upper.

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

[0152] Meanwhile, the glue gun 83 is connected to the hose of the external glue supply device through the interface 831 on the side, and the operation of the glue supply device is controlled to be synchronized with the driving motor 713. Thus, when the swing mechanism 82 swings, the glue gun 83 starts to apply glue.

[0153] Further, the support rod 81 is composed of a connecting pipe 811 and a connecting rod 812. The connecting rod 812 is movably sleeved in 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, on the support plate 71, support rods 81 are installed at both the top and bottom of the first transmission unit 72. The front ends of the connecting rods 812 of the two support rods 81 are fixed with mounting plates 821 on the opposite surfaces. The two mounting plates 821 are located at the top and bottom of the two rotating gears 822, ensuring the stability of the rotation of the rotating gears 822 and their meshing with the toothed rod 723.

[0155] A fixing screw rod 813 is threadedly connected to the side of the connecting pipe 811, and one end of the fixing screw rod 813 abuts against the side of the connecting rod 812.

[0156] More specifically, by rotating the fixing screw rod 813 clockwise and counterclockwise, the front end of the fixing screw rod 813 abuts against or disengages from the side of the connecting rod 812. When it abuts, the length of the support rod 81 is fixed, and when it disengages, the length of the support rod 81 can be adjusted.

[0157] In addition, when the platform plates 22 in the two frames approach the middle, and the lower die 4 and the upper die 5 are closed to press the shoe sole and shoe upper, the gluing member 8 is integrally attached to the opposite surfaces of the two platform plates 22, so as to ensure sufficient pressing of the shoe sole and shoe upper.

[0158] Further, the rebound mechanism 75 consists of a limit ring 751 and a tension spring 752. The limit ring 751 is fixed at 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, both ends of the tension spring 752 are in contact with the limit ring 751 and the support plate 71.

[0159] More specifically, when the moving rod 721 moves forward to the limit under the acting force of the meshing rotation of the transmission gear 741 and the transmission slot 724, the toothless part of the transmission gear 741 corresponds to the tooth profile in the transmission slot 724. At this time, under the push of the tension spring 752, the moving rod 721 drives the whole transmission unit one 72 to move backward to the initial position, and the tooth profile of the transmission gear 741 meshes and rotates with the tooth profile in the transmission slot 724 again, realizing the reciprocating movement of the whole transmission unit one 72.

[0160] Embodiment Five

[0161] Please refer to Figure 4 and Figures 9-13 As shown, the shoe sole and upper gluing device for shoe production proposed in this embodiment, on the basis of Embodiment Two, this embodiment further includes that the transmission unit two 73 includes a rotating knob 731 rotatably connected to one end of the support plate 71. A synchronous gear 732 is fixed at one end of the rotating knob 731, a linkage rod 734 is fixed at one end of the synchronous gear 732, and a plug rod 735 is provided at one end of the linkage rod 734.

[0162] The transmission unit two 73 further includes a screw rod 736 threadedly connected to the moving block 24. A plug-in block 737 is fixed at one end of the screw rod 736, and one end of the plug rod 735 is inserted into the plug-in block 737.

[0163] More specifically, the transmission unit two 73 adopts a separable design. By inserting the plug rod 735 into the plug-in block 737, when the synchronous gear 732 rotates, it drives the screw rod 736 to rotate at the same time, and under the acting force of the threaded connection between the screw rod 736 and the internal thread of the moving block 24, the moving block 24 drives the corresponding template to generate a displacement change.

[0164] It should be further noted that a round hole is provided on the side of the plug-in block 737, and the plug rod 735 and the screw rod 736 are vertically arranged at a right angle. Thus, when the round hole and the plug rod 735 are relatively arranged in the vertical direction, when the output end of the hydraulic rod 23 drives the platform plate 22 to achieve a height displacement change, the plug rod 735 is inserted into or disengaged from the round hole provided in the plug-in block 737.

[0165] Each time the synchronous gear 732 stops rotating, the round hole of the plug-in block 737 and the plug rod 735 are relatively arranged in the vertical direction, and after disengagement, the plug-in block 737 and the screw rod 736 still remain stationary in the vertical direction, which is convenient for reinsertion.

[0166] Further, a timing belt 733 is engaged between the synchronous gears 732 in the second transmission units 73 at both ends of the support plate 71.

[0167] More specifically, when any one of the synchronous gears 732 rotates, the other synchronous gear 732 is driven to rotate simultaneously through the timing belt 733, thereby realizing the rotation of the turntable of the double lead screws 736 and achieving the effect that the two templates are displaced in the same direction simultaneously.

[0168] Further, the transmission mechanism 74 includes a transmission gear 741 fixed to the output end of the driving motor 713. At the same time, a transmission slot 724 is formed on the side of the moving rod 721, and the transmission gear 741 is engaged in the transmission slot 724.

[0169] More specifically, the output end of the driving motor 713 has the function of bidirectional rotation. At the same time, the transmission gear 741 is a gear with missing teeth, and a tooth profile is provided at the bottom of the transmission slot 724. During operation, the output end drives the transmission gear 741 to rotate. Under the action of the engagement between the transmission gear 741 and the tooth profile in the transmission slot 724, the moving rod 721 drives the first transmission unit 72 to move forward as a whole.

[0170] Further, the transmission mechanism 74 further includes a driving gear 742 fixed to one end of the transmission gear 741. A linkage belt 743 is engaged on the side of the driving gear 742. A rotating gear 744 is engaged in the linkage belt 743. A first bevel gear 745 is fixed to one end of the rotating gear 744. A second bevel gear 746 is engaged on the side of the first bevel gear 745. One end of the second bevel gear 746 is fixed to the rotating knob 731.

[0171] More specifically, when the transmission gear 741 rotates, it drives the driving gear 742 to rotate simultaneously. At this time, the rotating gear 744 is driven to rotate simultaneously by using the linkage belt 743, so that the first bevel gear 745 and the second bevel gear 746 are engaged and rotated, thereby driving the synchronous gear 732 to rotate by the rotating knob 731 and achieving the effect of the rotation of the lead screw 736.

[0172] Further, a positioning plate 748 is rotatably connected to one ends of the driving gear 742 and the rotating gear 744.

[0173] More specifically, the driving gear 742 and the rotating gear 744 are respectively fixed to both ends of the positioning plate 748, improving the stability of the gear rotation and preventing the gear from disengaging from the belt.

[0174] Further, a stabilizing plate 747 is rotatably connected to the sides of the first bevel gear 745 and the second bevel gear 746.

[0175] More specifically, the stabilizing plate 747 is in a right-angled shape, and the first bevel gear 745 and the second bevel gear 746 are respectively fixed at both ends of the stabilizing plate 747, and the stability of the meshing of the two bevel gears is improved by the stabilizing plate 747.

[0176] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
