Description

Technical Field

[0001] This utility model relates to the field of shoe tree processing equipment, and in particular to a paper shoe tree forming machine. Background Technology

[0002] In existing technologies, paper shoe trees are mostly processed by feeding pre-cut paper material that matches the shape of the mold into left and right shoe tree forming devices. This requires pre-cut shoe tree blanks to be loaded into the hopper. For example, Chinese utility model patent CN221187691U discloses a fully automatic shoe tree forming machine, but it also relies on pre-cut shoe tree blanks for processing and lacks the ability to process rolled materials. This leads to a complex production process and increases production costs and pre-preparation work. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing a paper shoe tree forming machine.

[0004] To solve the above-mentioned technical problems, this utility model achieves its solution through the following technical solution:

[0005] A paper shoe tree forming machine includes left and right shoe tree forming devices, each with multiple stations equipped with molds. Shoe trees can be formed sequentially at each station. The left and right shoe tree forming devices include an infeed station and an outfeed station, as well as an unwinding frame and a rewinding frame. A die-cutting device is located between the unwinding frame and the rewinding frame. A finished product platform is located at the front end of the die-cutting device. A shoe tree transfer device transfers the die-cut finished products to a shoe tree conveying channel. A pusher head capable of moving the shoe trees is located within the shoe tree conveying channel. One end of the shoe tree conveying channel connects to the infeed station, and the other end connects to the shoe tree transfer device. Before the shoe trees are conveyed to the shoe tree conveying channel, at least one shoe tree can be turned. This machine achieves continuous die-cutting of paper materials, improves production efficiency, and ensures that shoe trees can smoothly transition from the die-cutting process to the forming process. The mold can be designed so that the left and right shoe trees are in opposite directions, thereby saving paper material. By turning, the shoe trees can be rotated to adapt to the state of the left and right shoe tree forming device, so that the left and right shoe trees can enter the forming station in the correct posture, ensuring the forming quality.

[0006] Preferably, the shoe tree transfer device is equipped with at least one pair of suction nozzles for adsorbing the left and right shoe trees. Adsorption ensures stable gripping of the shoe trees, preventing them from falling or shifting during transfer, thus improving the accuracy and stability of the transfer.

[0007] Preferably, at least one of the conveying nozzles is rotatable. This allows the shoe trees to be turned as needed during the transfer process, further enhancing the flexibility of the equipment and ensuring that the shoe trees enter the conveying channel and forming station in a state of left-right alignment with the mold.

[0008] Preferably, the conveying nozzle is mounted on the crossbeam, and the shoe support transfer device includes a laterally extending guide rail, on which the crossbeam is slidably mounted via a slider. This facilitates control over the transfer position and speed of the shoe support, improving the accuracy and stability of the transfer.

[0009] Preferably, the finished product platform has holes, and the bottom of the finished product platform has a directional suction nozzle. The directional suction nozzle extends upward through the holes to attract the shoe support. At least one of the directional suction nozzles can rotate to turn the shoe support.

[0010] Preferably, the bottom of the directional nozzle is connected to a swing arm, one end of which is connected to a rotational power source, and the directional nozzle is mounted on the other end of the swing arm. The swing arm can drive the directional nozzle to swing at least 180°.

[0011] Preferably, the finished product platform has a finished product adsorption station and a turning station. The finished product platform is provided with holes at the turning station, and the shoe support transfer device is provided with at least two pairs of conveying nozzles for adsorbing the left and right shoe supports.

[0012] Ideally, the finished product adsorption station and the turning station, the turning station and the entrance of the shoe support conveying channel, and the two pairs of conveying nozzles are equidistant. This ensures that the shoe supports are conveyed evenly between each station, making it easier to control the rhythm and speed of shoe support movement and improving production stability and consistency.

[0013] Preferably, the shoe tree transfer device is set perpendicular to the extension direction of the shoe tree conveying channel, and the conveying direction of the shoe tree transfer device is perpendicular to the conveying direction of the die-cutting device. This layout design makes the entire production process more compact and reasonable, makes full use of space, reduces the equipment footprint, and facilitates the connection and cooperation between various devices.

[0014] Preferably, the left and right shoe tree forming device includes a turntable with multiple stations arranged around its circumference. Each station has a mold for processing the left and right shoe trees. The turntable design allows the shoe trees to pass through each station sequentially during the forming process, achieving continuous forming and improving forming efficiency.

[0015] Preferably, a gluing device and a high-temperature laminating device are also provided between the unwinding frame and the rewinding frame. The gluing device is used to apply glue to the passing roll material, which is then conveyed to the high-temperature laminating device and the die-cutting device in sequence by the conveyor roller.

[0016] This utility model, by adopting the above technical solution, has significant technical effects:

[0017] This technology enables roll-to-roll processing, eliminating the need for pre-prepared die-cut shoe tree blanks. Die-cutting and forming are performed directly from the roll material, reducing intermediate steps. It solves the problem of lacking roll-to-roll processing technology for paper shoe trees, overcomes the limitations of relying on pre-cut shoe tree blanks, simplifies the production process, and reduces pre-processing work.

[0018] The mold can be designed so that the left and right shoe trees are in opposite directions, thereby saving paper material. By turning, the shoe trees can be rotated to adapt to the state of the left and right shoe tree forming device, so that the left and right shoe trees can enter the forming station in the correct posture, ensuring the forming quality.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] A paper shoe tree forming machine, such as Figure 1-4As shown, the device includes a left and right shoe support forming device 1, which includes multiple stations with molds 11. Shoe supports can be formed sequentially at each station. The left and right shoe support forming device 1 includes a feeding station 12 and a discharging station 13, as well as an unwinding frame 21 and a winding frame 22. A die-cutting device 23 is provided between the unwinding frame 21 and the winding frame 22. A finished product platform 3 is provided at the front end of the die-cutting device 23. A shoe support transfer device 4 transfers the die-cut finished product to a shoe support conveying channel 5. A pusher head that can move shoe supports is provided in the shoe support conveying channel 5. One end of the shoe support conveying channel 5 is connected to the feeding station 12, and the other end of the shoe support conveying channel 5 is connected to the shoe support transfer device 4. Before the shoe support is conveyed to the shoe support conveying channel 5, at least one shoe support can be turned.

[0027] The shoe support transfer device 4 is equipped with at least one pair of conveying nozzles 41 for adsorbing the left and right shoe supports.

[0028] The conveying nozzle 41 is installed on the crossbeam 42, and the shoe support transfer device 4 includes a laterally extending guide rail 44. The crossbeam 42 is slidably mounted on the guide rail 44 by a slider 43.

[0029] The finished product platform 3 has holes 31, and the bottom of the finished product platform 3 has a directional suction nozzle 32. The directional suction nozzle 32 extends upward from the holes 31 to attract the shoe support. At least one of the directional suction nozzles 32 can rotate to turn the shoe support. The other directional suction nozzle 32 can rotate or not rotate. If it does not rotate, the other shoe support may not have a directional suction nozzle 32 and may use other support methods, as long as it is not easy for the shoe support to shift horizontally on it. It only exists as a connecting station for the two conveying suction nozzles 41. As one way to realize the rotation of the directional suction nozzle 32, the bottom of the directional suction nozzle 32 is connected to a swing arm 33. One end of the swing arm 33 is connected to a rotational power source, and the directional suction nozzle 32 is installed on the other end of the swing arm 33. The swing arm 33 can drive the directional suction nozzle 32 to swing at least 180°. The bottom of the directional suction nozzle is connected to the swing arm, and the swing arm drives the directional suction nozzle to swing under the drive of the rotational power source, so as to realize the turning adjustment of the shoe support.

[0030] The finished product platform 3 has a finished product adsorption station and a turning station. The finished product platform 3 is provided with a hole 31 at the turning station. The shoe support transfer device 4 is provided with at least two pairs of conveying nozzles 41 for adsorbing the left and right shoe supports.

[0031] The finished product adsorption station and the turning station are equidistant, as are the turning station and the entrance of the shoe support conveying channel 5, and the two pairs of conveying nozzles 41.

[0032] The arrangement of the machine body can be a conveyor line, an L-shaped conveyor, or the shoe support transfer device 4 can be set perpendicular to the extension direction of the shoe support conveyor channel 5, and the conveying direction of the shoe support transfer device 4 can be perpendicular to the conveying direction of the die-cutting device 23.

[0033] The left and right shoe support forming device 1 includes a turntable, and multiple workstations are arranged around the turntable. Each workstation is provided with a mold 11 for processing the left and right shoe supports.

[0034] Between the unwinding frame 21 and the rewinding frame 22, the roll material is further equipped with an adhesive application device 24 and a high-temperature laminating device 25. The adhesive application device 24 applies adhesive to the passing roll material, which is then conveyed sequentially to the high-temperature laminating device 25 and the die-cutting device 23 via conveyor rollers. When the roll material has at least two layers, the roll material can be of the same material or different materials. After laminating different roll materials with adhesive, sending them to the high-temperature laminating device 25 allows the moisture in the adhesive to evaporate, thus bonding the roll materials together. Alternatively, after the adhesive has dried, the multi-layered roll material can be further laminated in the high-temperature laminating device 25 to increase its strength.

[0035] Working principle:

[0036] The roll of material is placed on the unwinding rack and moves between the unwinding and rewinding racks. When it passes through the die-cutting device, the die-cutting device cuts the roll of material into the shape of left and right shoe trees. The die-cut shoe trees are then placed on the finished product platform.

[0037] The conveying nozzle 41 on the shoe support transfer device adsorbs the shoe support to the position of the hole provided on the finished product platform, or the left and right shoe supports after die cutting are conveyed to the position of the hole provided on the finished product platform by the finished product platform itself. The bottom directional nozzle extends upward through the hole to adsorb the shoe support, and at least one directional nozzle 32 can rotate to turn the shoe support.

[0038] Then, the suction nozzle picks up the shoe trees aligned with the suction nozzle 32, and the shoe trees are moved from the finished product platform to the shoe tree conveying channel by sliding the slider on the guide rail. The pusher head in the shoe tree conveying channel moves the shoe trees to the feeding station 12. The left and right shoe tree forming device includes multiple stations with molds, and the shoe trees are formed sequentially at each station. The turntable of the left and right shoe tree forming device drives the station to rotate, and the mold at each station processes the left and right shoe trees synchronously. Finally, the formed shoe trees are taken out and sent out at the discharge station 13.

[0039] Example 2

[0040] It is basically the same as Embodiment 1, except that the rotation method is different. At least one of the conveying nozzles 41 can rotate. After the conveying nozzle 41 picks up the paper material, the shoe support is adjusted by rotating through the mounting base of the conveying nozzle 41 or by the conveying nozzle 41 itself.

[0041] The conveying nozzles 41 on the crossbeam have at least one pair corresponding to the left and right shoe support blanks. They pick up the left and right shoe supports on the finished product platform 3 and rotate during the conveying process. Then the conveying nozzles 41 reach the shoe support conveying channel 5.
