Description

Technical Field

[0001] This invention relates to the field of composite physical training shoe manufacturing technology, and in particular to a bonding and pressing device for the inner insole layer of a composite physical training shoe. Background Technology

[0002] Composite physical training shoes are a type of hybrid sports shoe designed to meet diverse physical training needs and adapt to various physical training activities. These shoes typically combine multiple sports elements to provide comprehensive support, cushioning, and comfort to suit different training scenarios and movements.

[0003] Among them, the composite insole is an important component of sports shoes such as physical training shoes. It is an inner layer of the sole made of a variety of different materials. It is located between the sole and the insole and plays a role in supporting, cushioning and protecting the feet. For example, the composite sponge insole combines a base layer, a middle layer and a top sponge. For specific foot types such as flat feet or high arches, insole with corresponding support or cushioning functions can also be selected to optimize the training effect.

[0004] Multi-layered composite inner pads are typically bonded together using adhesive methods. Based on the shape and size requirements of the inner pad, molten material is injected into the mold cavity using an injection molding machine. After cooling and solidification, the inner pad is formed. Adhesive is then applied and the pad is adhered to the designated location, pressed for a period of time, and allowed to fully solidify. In actual production, to save bonding time and improve efficiency, adhesive is usually applied to the surface of the inner pad beforehand to significantly shorten bonding time. However, the pre-applied adhesive needs to be bonded within a certain timeframe; excessive waiting time may affect the adhesive's bonding effect. Furthermore, during transport on the assembly line, foreign objects may come into contact with the adhesive, causing it to fail or contaminating the inner pad. Summary of the Invention

[0005] The purpose of this invention is to address the problems that pre-applied adhesive needs to be bonded within a certain time, and that excessive waiting time may affect the bonding effect of the adhesive, and that foreign objects may come into contact with the adhesive during the transport process on the production line, leading to adhesive failure or contamination of the inner padding layer. Therefore, this invention proposes a bonding and pressing device for the inner padding layer of composite soles for physical training shoes.

[0006] To achieve the above objectives, the present invention employs the following technology: a bonding and pressing device for the inner insole layer of a composite shoe sole for physical training shoes.

[0007] The device includes a bonding and pressing equipment body and a composite inner pad layer. The bonding and pressing equipment body includes a base and a storage cavity disposed above the base. The composite inner pad layer includes a base inner pad layer and several reinforcing inner pad layers bonded to the base inner pad layer. An inner pad layer placement tray for placing the base inner pad layer is slidably disposed on the base. The storage cavity stores the reinforcing inner pad layer and has a glue roller and glue head disposed below it for applying glue to the reinforcing inner pad layer. The glue roller and glue head are reciprocated by a coating mechanism.

[0008] The coating mechanism includes a mounting cavity on the base, a mounting plate slidably disposed in the mounting cavity, and a half-tooth gear rotatably disposed in the middle of the mounting plate. The mounting plate is provided with teeth that mesh with the half-tooth gear. When the mounting plate rotates, the teeth work together to push the mounting plate to move back and forth. The rubber roller and rubber head are disposed on the mounting plate.

[0009] The storage cavity is equipped with a feeding mechanism, which includes a lifting and lowering material picker. When the material picker descends, it pushes the reinforcing inner pad layer to contact the rubber roller and rubber head and applies glue. When the inner pad layer placement support drives the basic inner pad layer to slide below the reinforcing inner pad layer, the material picker pushes the reinforcing inner pad layer out of the storage cavity and presses it onto the basic inner pad layer.

[0010] As a further description of the bonding and pressing equipment for the composite insole layer of a physical training shoe described above: the coating mechanism also includes a bearing frame installed in the mounting cavity, and a half-tooth gear is rotatably mounted on the bearing frame;

[0011] The number of teeth on both sides of the inner wall of the mounting plate is the same as the number of teeth on the upper gear of the half gear. When the half gear rotates one revolution, it works with the teeth to push the mounting plate to complete one reciprocating movement.

[0012] Mounting brackets are installed at both ends of the mounting plate, and the rubber roller and rubber head are mounted on the teeth through the mounting brackets.

[0013] As a further description of the bonding and pressing device for the inner padding layer of the composite sole of the physical training shoe mentioned above: the half gear is driven to rotate by a pushing mechanism, the pushing mechanism includes a pushing groove set in the middle of the base, a bracket is slidably embedded in the pushing groove, and the inner padding layer is placed on the bracket;

[0014] A threaded ring is fixedly installed in the middle of the bracket, and a rotating rod is provided through the middle of the threaded ring. The surface of the rotating rod is provided with threaded ribs that fit into the threaded ring and surround the rotating rod. The rotating rod is rotatably set in the push groove. When the threaded ring moves, it works with the threaded ribs to drive the rotating rod to rotate one revolution.

[0015] The rotating rod is also fitted with a first bevel gear, and the bearing bracket is fitted with a second bevel gear that meshes with the second bevel gear.

[0016] As a further description of the bonding and pressing equipment for the composite insole layer of a physical training shoe as described above: the feeding mechanism also includes several inclined positioning plates arranged in the storage cavity. The positioning plates are provided with guide rails, and sliding members are slidably arranged on the guide rails. Telescopic rails and pull rods are installed on the sliding members. The material picking member is slidably embedded in the telescopic rails and fits against the surface of the positioning plates. The material picking member moves up and down with the sliding members, and the pull rod extends through to the outside of the storage cavity.

[0017] The distance between the material taking component and the reinforcing inner padding layer gradually decreases from top to bottom. As the material taking component descends, it approaches the reinforcing inner padding layer and gradually inserts into the gap between two adjacent reinforcing inner padding layers. The material taking component drives the reinforcing inner padding layer below to descend within the storage cavity.

[0018] As a further description of the bonding and pressing equipment for the composite insole layer of a physical training shoe as described above: the positioning plate has an arc-shaped rolling groove on its surface, the material taking part is equipped with a ball cavity, and a rolling ball is embedded in the ball cavity, the ball rolling against the surface of the rolling groove.

[0019] As a further description of the bonding and pressing device for the composite insole layer of a physical training shoe as described above: guide rods are provided inside both sides of the sliding member, and a return spring is wound around the surface of the guide rods;

[0020] The material taking component has fitting blocks on both sides, which are inserted into the sliding component and sleeved on the surface of the guide rod.

[0021] As a further description of the bonding and pressing device for the composite insole layer of a physical training shoe as described above: the material taking part is set in a Z shape, and when the sliding part is attached to the bottom of the inner wall of the storage cavity, the material taking part penetrates through the bottom of the storage cavity.

[0022] As a further description of the bonding and pressing device for the composite insole of a physical training shoe as described above: a pusher is provided inside the storage cavity, the bottom of the pusher is attached to the reinforced insole stored in the storage cavity, a rotatable rigid stopper is provided below the reinforced insole for preventing falling, and a deformable flexible stopper is provided at the bottom of the storage cavity for preventing falling.

[0023] The material taking component is inserted above the reinforcing inner padding layer of the pusher component, presses down to release the restriction of the rigid stop and pushes the reinforcing inner padding layer to the flexible stop. After the reinforcing inner padding layer and the material taking component are removed, the pusher component resets. The rigid stop pushes the next reinforcing inner padding layer to adhere to the pusher component. The material taking component continues to press down to release the restriction of the flexible stop and move the reinforcing inner padding layer out of the storage cavity.

[0024] As a further description of the bonding and pressing equipment for the composite insole layer of a physical training shoe as described above: the position of the material is fixed by a pressing mechanism, the pressing mechanism includes a rotating cavity opened on a sliding member, a rotating shaft is rotatably arranged in the rotating cavity, a pull rod is installed on the rotating shaft and a gradient protrusion is sleeved and installed in the middle of the rotating shaft;

[0025] The rotating cavity has chambers on both sides for the gradual protrusion to rotate into. A pin is inserted through the chamber. When the gradual protrusion enters the chamber, it pushes the pin to move.

[0026] The inner wall of the storage cavity is provided with a socket for inserting a pin.

[0027] As a further description of the bonding and pressing device for the composite insole layer of a physical training shoe described above: a compression spring is wound around the surface of the pin, and the elastic deformation of the compression spring can push the pin to reset but cannot push the gradient protrusion to rotate.

[0028] In summary, due to the adoption of the above-mentioned technology in the bonding and pressing device for the composite insole layer of a physical training shoe, the beneficial effects of this invention are:

[0029] 1. Through the coating and pushing mechanisms, when the inner padding layer is placed and pushed, the first bevel gear drives the half-tooth gear to rotate under the constraint of the bearing bracket through the second bevel gear. The teeth on the half-tooth gear contact the teeth on both sides of the inner wall of the mounting plate in sequence and push the mounting plate to move back and forth once inside the mounting cavity. The mounting plate drives the glue head to contact the bottom of the reinforced inner padding layer through the mounting frame, and applies glue to the reinforced inner padding layer. Then, the mounting frame on the other side drives the glue roller to contact the bottom of the reinforced inner padding layer, and evenly spreads the glue on the reinforced inner padding layer. The glue application on the reinforced inner padding layer is completed. This achieves the purpose of applying glue to the reinforced inner padding layer by the coating mechanism at the same time as pushing the base inner padding layer to the pressing position. This avoids the problem of excessive waiting time after applying glue in advance, which affects the adhesive effect of the glue. It also reduces the chance of foreign objects coming into contact with the glue and avoids the situation of glue failure or contamination of the inner padding layer.

[0030] 2. The pressing mechanism ensures a more stable bond between the base inner pad and the reinforcing inner pad. After the material take-up component pushes the reinforcing inner pad out of the storage cavity and presses it onto the surface of the base inner pad, the pull rod can be rotated. This causes the pull rod to drive the rotating shaft and the gradient protrusion to rotate. The gradient protrusion rotates into the cavity and pushes the pin. The pin extends out from inside the cavity and inserts into the insertion hole. The compression spring, in conjunction with the insertion hole, fixes the position of the material take-up component, preventing it from lifting. This ensures the stability of the pressing. Furthermore, depending on the type of reinforcing inner pad to be bonded to the base inner pad, the rotation direction of the pull rod can be selected to avoid mutual interference. For example, if all three types of reinforcing inner pads need to be bonded to the base inner pad, the rotation direction of the three pull rods must be the same. If the middle reinforcing inner pad does not need to be bonded to the base inner pad, the pull rods on both sides can rotate in opposite directions. Attached Figure Description

[0055] The following will describe, with reference to the accompanying drawings of the embodiments of the present invention, a bonding and pressing device for the inner insole of a composite shoe sole of a physical training shoe. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0056] To address the issue that pre-applied adhesive needs to bond within a certain timeframe, and that excessive waiting time may affect the adhesive's bonding effect, and that foreign objects may come into contact with the adhesive during transport on the assembly line, leading to adhesive failure or contamination of the inner insole layer, this invention proposes a bonding and pressing device for the inner insole layer of a composite sole in physical training shoes. Figure 1 - Figure 17 As shown:

[0057] The device includes a bonding and pressing equipment body 10 and a composite inner pad 20. The bonding and pressing equipment body 10 includes a base 11 and a storage cavity 12 disposed above the base 11. The composite inner pad 20 includes a base inner pad 21 and a plurality of reinforcing inner pads 22 bonded to the base inner pad 21. An inner pad placement tray 13 for placing the base inner pad 21 is slidably disposed on the base 11. The storage cavity 12 stores the reinforcing inner pads 22 and has a glue roller 14 and a glue head 15 for applying glue to the reinforcing inner pads 22 disposed below it.

[0058] The storage cavity 12 is equipped with a feeding mechanism 50, which includes a lifting and lowering material picking component 55. When the material picking component 55 descends, it pushes the reinforcing inner pad 22 to contact the rubber roller 14 and the rubber head 15 and applies glue. When the inner pad placement support 13 drives the base inner pad 21 to slide below the reinforcing inner pad 22, the material picking component 55 pushes the reinforcing inner pad 22 out of the storage cavity 12 and presses it onto the base inner pad 21.

[0059] The feeding mechanism 50 also includes three inclined positioning plates 51 disposed in the storage cavity 12. The positioning plates 51 are provided with guide rails 52, and sliding members 53 are slidably disposed on the guide rails 52. Telescopic rails 54 and pull rods 56 are installed on the sliding members 53. The picking member 55 is slidably embedded in the telescopic rails 54 and fits against the surface of the positioning plates 51. The picking member 55 moves up and down with the sliding members 53. The pull rods 56 extend through to the outside of the storage cavity 12.

[0060] The distance between the material picker 55 and the reinforcing inner pad 22 gradually decreases from top to bottom. During the descent, the material picker 55 approaches the reinforcing inner pad 22 and gradually inserts into the gap between two adjacent reinforcing inner pads 22. The material picker 55 drives the reinforcing inner pad 22 below to descend within the storage cavity 12.

[0061] A pusher 121 is provided inside the storage cavity 12. The bottom of the pusher 121 is in contact with the reinforcing inner padding layer 22 stored inside the storage cavity 12. Below the reinforcing inner padding layer 22, a rotatable rigid stop 122 is provided to prevent it from falling. At the bottom of the storage cavity 12, a deformable flexible stop 123 is provided to prevent it from falling. The inner wall of the flexible stop 123 is provided with multiple elastic protrusions that contact and abut against the reinforcing inner padding layer 22. The elastic protrusions allow the bottom of the reinforcing inner padding layer 22 to extend to a position below the flexible stop 123 without completely falling out of the flexible stop 123. Figure 15 As shown;

[0062] When it is necessary to push the reinforcing inner pad 22 out of the storage cavity 12, push the pull rod 56 upward, so that the pull rod 56 drives the sliding member 53 to move under the restriction of the guide rail 52. The sliding member 53 drives the picking member 55 to move against the surface of the positioning plate 51 through the telescopic rail 54. As the picking member 55 rises, the positioning plate 51 no longer pushes the picking member 55 to move towards the reinforcing inner pad 22. The picking member 55 moves in the opposite direction until it is completely nested on the telescopic rail 54.

[0063] After the material picker 55 reaches the top, the pull rod 56 is pushed down, causing the pull rod 56 to lower the material picker 55. At the same time, the positioning plate 51 pushes the material picker 55 to move horizontally. At this time, the material picker 55 can be inserted above the reinforcing inner pad 22 of the pusher 121. As the material picker 55 is pressed down, the material picker 55 squeezes and releases the rigid stop 122 and pushes the reinforcing inner pad 22 to the flexible stop 123. After the reinforcing inner pad 22 and the material picker 55 are removed, the pusher 121 is reset. The rigid stop 122 pushes the next reinforcing inner pad 22 to adhere to the pusher 121.

[0064] In order to improve the smoothness of the movement of the positioning plate 51 pushing the picking part 55, such as Figure 11 , Figure 12 and Figure 13 As shown, the positioning plate 51 has an arc-shaped rolling groove 511 on its surface, and the picking component 55 is equipped with a ball cavity 551. The ball cavity 551 is embedded with a rolling ball 552. The ball 552 rolls against the surface of the rolling groove 511. The picking component 55 and the positioning plate 51 are in contact through the rolling groove 511 and the ball 552. Therefore, the friction of the picking component 55 when it moves against the surface of the positioning plate 51 is reduced, and the smoothness of the movement of the picking component 55 is improved.

[0065] At the same time, such as Figure 14 As shown, guide rods 531 are provided inside both sides of the slider 53, and a return spring 532 is wound around the surface of the guide rods 531.

[0066] The material taking part 55 is provided with fitting blocks 533 on both sides. The fitting blocks 533 are inserted into the sliding part 53 and sleeved on the surface of the guide rod 531.

[0067] This design enables the picking component 55 to move the interlocking block 533 on the surface of the guide rod 531 and squeeze the return spring 532 as it moves downward. The return spring 532 undergoes elastic deformation, allowing the picking component 55 to recover its position by utilizing the elastic deformation of the return spring 532 when it moves upward. This ensures that the picking component 55 is always in contact with the surface of the positioning plate 51, guaranteeing that it can be completely nested with the telescopic track 54 when it reaches the top of the positioning plate 51.

[0068] The bottom of the reinforced inner padding layer 22, which reaches the flexible stopper 123, is lower than the bottom of the storage cavity 12. Simultaneously, due to the obstruction of the flexible stopper 123, the reinforced inner padding layer 22 cannot be completely removed from the storage cavity 12. At this point, the basic inner padding layer 21 can be placed on the inner padding layer placement tray 13, and the inner padding layer placement tray 13 can be pushed. A pushing mechanism 40 is provided below the inner padding layer placement tray 13. Figure 3 , Figure 7 and Figure 8 As shown;

[0069] The pushing mechanism 40 includes a pushing groove 41 disposed in the middle of the base 11, a bracket 43 is slidably embedded in the pushing groove 41, and an inner padding layer placement support 13 is mounted on the bracket 43.

[0070] A threaded ring 44 is fixedly installed in the middle of the bracket 43, and a rotating rod 42 is provided through the middle of the threaded ring 44. The surface of the rotating rod 42 is provided with a threaded rib 45 that is engaged with the threaded ring 44 and surrounds the rotating rod 42 for one revolution. The rotating rod 42 is rotatably installed in the push groove 41. When the threaded ring 44 moves, it cooperates with the threaded rib 45 to drive the rotating rod 42 to rotate one revolution.

[0071] When the inner padding layer placement support 13 is pushed, the inner padding layer placement support 13 drives the bracket 43 to move inside the pushing groove 41. At the same time, the bracket 43 drives the threaded ring 44 to move on the surface of the rotating rod 42. With the cooperation of the threaded ring 44 and the threaded rib 45, the rotating rod 42 drives the first bevel gear 46 to rotate one revolution. At the same time, the inner padding layer placement support 13 drives the basic inner padding layer 21 to reach below the reinforced inner padding layer 22.

[0072] As the base inner pad 21 moves below the reinforcing inner pad 22, the rubber roller 14 and the rubber head 15 apply adhesive to the surface of the reinforcing inner pad 22. The rubber roller 14 and the rubber head 15 reciprocate via the coating mechanism 30. Figure 5 and Figure 6 ;

[0073] The coating mechanism 30 includes a mounting cavity 31 opened on the base 11, a mounting plate 32 slidably disposed in the mounting cavity 31, and a half-tooth gear 35 rotatably disposed in the middle of the mounting plate 32. The mounting plate 32 is provided with teeth 33 that mesh with the half-tooth gear 35. When the mounting plate 32 rotates, the teeth 33 push the mounting plate 32 to reciprocate. The rubber roller 14 and the rubber head 15 are disposed on the mounting plate 32.

[0074] The coating mechanism 30 also includes a bearing bracket 36 installed in the mounting cavity 31, and a half-tooth gear 35 is rotatably mounted on the bearing bracket 36;

[0075] The number of teeth 33 on both sides of the inner wall of the mounting plate 32 is the same as the number of teeth on the upper gear 35. When the half gear 35 rotates one revolution, it works with the teeth 33 to push the mounting plate 32 to complete one reciprocating movement.

[0076] Mounting brackets 34 are installed at both ends of the mounting plate 32, and the rubber roller 14 and rubber head 15 are mounted on the teeth 33 through the mounting brackets 34.

[0077] A first bevel gear 46 is also fitted onto the rotating rod 42, and a second bevel gear 47 that meshes with the second bevel gear 47 is installed on the bearing bracket 36;

[0078] During the movement of the inner padding layer placement bracket 13 and the base inner padding layer 21, the rotating rod 42 will drive the first bevel gear 46 to rotate one revolution. At this time, the first bevel gear 46 drives the half gear 35 to rotate under the constraint of the bearing bracket 36 through the second bevel gear 47. The teeth on the half gear 35 contact the teeth 33 on both sides of the inner wall of the mounting plate 32 in sequence and push the mounting plate 32 to move back and forth once inside the mounting cavity 31. This causes the mounting plate 32 to drive the glue head 15 to contact the bottom of the reinforced inner padding layer 22 through the mounting bracket 34, and apply glue to the reinforced inner padding layer. On the 22, the mounting bracket 34 on the other side drives the glue roller 14 to contact the bottom of the reinforcing inner pad 22, and the glue is evenly applied to the reinforcing inner pad 22. The glue application on the reinforcing inner pad 22 is completed, thereby achieving the purpose of applying glue to the reinforcing inner pad 22 by the coating mechanism 30 while pushing the base inner pad 21 to the pressing position. This avoids the problem of excessive waiting time after the glue is applied in advance, which affects the bonding effect of the glue, and reduces the chance of foreign objects coming into contact with the glue, avoiding the situation of glue failure or contamination of the inner pad.

[0079] Because the material taking part 55 is set in a Z shape, such as Figure 13As shown, when the sliding member 53 is attached to the bottom of the inner wall of the storage cavity 12, the material taking member 55 penetrates the bottom of the storage cavity 12. Through this design, the material taking member 55 continues to press down to release the restriction of the flexible blocking member 123 and move the reinforcing inner pad 22 out of the storage cavity 12. At this time, the reinforcing inner pad 22 can be attached to the base inner pad 21 and pressed by the material taking member 55 until the glue on the base inner pad 21 and the reinforcing inner pad 22 is completely solidified.

[0080] To ensure a more stable bonding between the base inner padding layer 21 and the reinforcing inner padding layer 22, the position of the material take-up component 55 is fixed by the pressing mechanism 60, such as... Figure 14 , Figure 16 and Figure 17 As shown, the pressing mechanism 60 includes a rotating cavity 61 opened on the sliding member 53, a rotating shaft 62 is rotatably arranged in the rotating cavity 61, a pull rod 56 is installed on the rotating shaft 62, and a gradient protrusion 63 is sleeved on the middle of the rotating shaft 62.

[0081] The rotating cavity 61 has chambers 64 on both sides for the gradual protrusion 63 to rotate into. A pin 65 is inserted through the chamber 64. When the gradual protrusion 63 enters the chamber 64, it pushes the pin 65 to move.

[0082] The inner wall of the storage cavity 12 is provided with a socket 67 for inserting a pin 65;

[0083] After the material take-up component 55 pushes the reinforcing inner pad 22 out of the storage cavity 12 and presses it onto the surface of the base inner pad 21, the pull rod 56 can be rotated. This causes the pull rod 56 to drive the rotating shaft 62 and the gradient protrusion 63 to rotate. The gradient protrusion 63 rotates into the cavity 64 and squeezes and pushes the pin 65. The pin 65 extends out from the cavity 64 and inserts into the insertion hole 67. The compression spring 66, in conjunction with the insertion hole 67, fixes the position of the material take-up component 55 so that it cannot be lifted, thereby ensuring the stability of the pressing. At the same time, depending on the type of reinforcing inner pad 22 to be bonded to the base inner pad 21, the rotation direction of the pull rod 56 can be selected to avoid mutual interference. For example, when all three types of reinforcing inner pad 22 need to be bonded to the base inner pad 21, the rotation direction of the three pull rods 56 must be the same. When the middle reinforcing inner pad 22 does not need to be bonded to the base inner pad 21, the pull rods 56 on both sides can rotate in opposite directions.

[0084] In order to allow the pin 65 to retract from the socket 67 to release the restriction on the position of the picking part 55, a compression spring 66 is wound around the surface of the pin 65. The elastic deformation of the compression spring 66 can push the pin 65 to reset and cannot push the gradient protrusion 63 to rotate.
