[0002] The bonding strength between the upper and the sole of a footwear product generally refers to the bonding strength between the shoe upper (the upper part of the shoe) and the sole (the bottom of the shoe). This bonding strength is very important because it is related to the structural stability and service life of the shoe. Generally speaking, the bonding strength between the upper and the sole of a footwear product needs to meet the requirements of national or industrial standards to ensure the quality and safety of the shoe. During the production process, it is necessary to detect its strength.

[0003] After detecting the bonding strength of the upper and the sole of a footwear product, the quality and safety performance of the footwear can be ensured. However, there are the following problems in the existing devices: when the device detects a footwear product, it is necessary to fix the footwear, usually by manual operation, which is rather cumbersome and reduces the detection efficiency, making the device less practical. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem in the existing technology that when a device detects a footwear product, it is necessary to fix the footwear, usually by manual operation, which is rather cumbersome and reduces the detection efficiency, making the device less practical. A detection device for the bonding strength of the middle part and the sole of a footwear product is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A detection device for the bonding strength of the middle part and the sole of a footwear product includes a bottom plate, an upper plate, a top plate and two brackets. The top of the bottom plate is fixedly connected to the bottom of the upper plate. Support columns are fixedly connected to the four corners of the bottom of the bottom plate. The shapes of the two brackets are both L-shaped. The closer sides of the two brackets are respectively fixedly connected to the two sides of the same bottom plate. The two sides of the bottom of the top plate are respectively fixedly connected to the tops of the two brackets. Diagonal rods are fixedly connected to the front and rear sides of the two brackets. One ends of multiple diagonal rods are respectively fixedly connected to the two sides of the bottom of the same top plate. A controller is fixedly connected to one side of the bottom plate;

[0007] A fixing mechanism, which is arranged on the top of the bottom plate for fixing the sole;

[0008] A lifting mechanism, which is arranged on the top plate for detecting the bonding strength of the footwear;

[0009] A clamping mechanism, which is arranged on the lifting mechanism for clamping the shoe upper.

[0010] In a possible design, the fixing mechanism includes two electric telescopic rods, four sliding rods and two clamping plates. The fixed ends of the two electric telescopic rods are respectively fixedly connected to both sides of the top of the same bottom plate. One end blocks are fixedly connected to the telescopic ends of the two electric telescopic rods. One sides of the two one end blocks close to each other are respectively fixedly connected to the separated sides of the two clamping plates. The two clamping plates are respectively located on both sides of the top of the same upper plate. One ends of the four sliding rods are respectively fixedly connected to both sides of the top of the same bottom plate. Limit plates are fixedly connected to the other ends of the four sliding rods. Second blocks are slidably sleeved on the four sliding rods. One sides of the four second blocks are respectively fixedly connected to the sides of the two clamping plates away from each other.

[0011] In a possible design, the lifting mechanism includes an electric telescopic column and a tension sensor. A round hole is formed in the top plate. The outer side of the fixed end of the electric telescopic column is fixedly connected to the inner wall of the round hole. The telescopic end of the electric telescopic column is fixedly connected to the top of the tension sensor. A cylinder is fixedly connected to the bottom of the tension sensor. A connecting plate for facilitating the clamping of the shoe upper is fixedly connected to one end of the cylinder.

[0012] In a possible design, the clamping mechanism includes a motor, a bidirectional lead screw and two clamping blocks. The two ends of the bidirectional lead screw are respectively rotatably connected to third blocks. One side of the motor is fixedly connected to one side of the third block through a bolt. The output shaft of the motor penetrates through the third block and is fixedly connected to one end of the bidirectional lead screw.

[0015] In this application, when in use, place the footwear to be detected on the upper plate. Then, start the electric telescopic rod through the controller. The telescopic end of the electric telescopic rod drives the two clamping plates to move up and down under the limitation of the sliding rod, and clamp the sole of the footwear. The rubber pads are used to reduce damage to the footwear and ensure stable clamping. After the sole is clamped, drive the electric telescopic column through the controller. The telescopic end of the electric telescopic column drives the tension sensor and the connecting plate to move up and down, facilitating the clamping of the shoe upper and also convenient for detecting the footwear. Then, drive the motor through the controller. The motor drives the two arc-shaped clamping blocks to clamp the shoe upper through the bidirectional lead screw. After clamping, control the electric telescopic column to pull the shoe upper through the controller.

[0026] The top of the bottom plate 1 and the bottom of the upper plate 2 are connected together by welding or other fixing means, providing a stable support for the sole. Support columns are installed at the four corners of the bottom of the bottom plate 1 to increase the stability of the entire device. The two brackets 3 are in an L-shaped structure, and their inner sides are fixedly connected to both sides of the bottom plate 1. The bottom of the top plate 4 is fixedly connected to the tops of the two brackets 3, forming a stable framework. In addition, in order to increase the structural strength, diagonal rods are installed on the front and rear sides of the brackets 3, and one end of the diagonal rod is fixedly connected to the bottom of the top plate 4.

[0027] On one side of the bottom plate 1, we installed a controller 5 for controlling the operation of the entire detection device. The controller 5 can be a programmable logic controller or a simple control panel, and it connects and controls electric components such as the electric telescopic rod 10, the electric telescopic column 11, and the motor 15 in the device.

[0028] The fixing mechanism is designed to firmly fix the sole. It includes two electric telescopic rods 10, four sliding rods 9 and two clamping plates 8. The fixed ends of the electric telescopic rods 10 are fixed on the top of the bottom plate 1, and the telescopic ends are connected with a first block, and the first block is fixedly connected to one side of the clamping plate 8. When the electric telescopic rod 10 expands and contracts, the clamping plate 8 will move accordingly, thereby clamping the sole. One end of the sliding rod 9 is fixed on the bottom plate 1, and the other end is provided with a limiting plate. A second block is sleeved on the sliding rod 9, and the second block is fixedly connected to the other side of the clamping plate 8, which can ensure the stability of the clamping plate 8 when it moves. A rubber pad 7 is also installed at the bottom of the clamping plate 8 to reduce damage to the sole.

[0029] The lifting mechanism is designed to detect the bonding strength of the shoe upper. It includes an electric telescopic column 11 and a tensile sensor 12. The fixed end of the electric telescopic column 11 is fixed on the top plate 4, and the telescopic end is connected to the tensile sensor 12. When the electric telescopic column 11 expands and contracts, the tensile sensor 12 will move up and down accordingly, and then detect the bonding strength of the shoe upper, and at the same time facilitate the clamping of the shoe upper.

[0030] The clamping mechanism is to firmly clamp the shoe upper. It includes a motor 15, a bidirectional lead screw 16 and two clamping blocks 14. The output shaft of the motor 15 is connected to one end of the bidirectional lead screw 16. When the motor 15 rotates, the bidirectional lead screw 16 will rotate accordingly, thereby driving the two clamping blocks 14 to approach or move away from each other to realize the clamping of the shoe upper. A sliding block is provided at the top of the clamping block 14, and the sliding block is slidably connected to the bottom of the connecting plate 13, so that the clamping block 14 can maintain stability when moving. The shape of the clamping block 14 is designed to be arc-shaped to better clamp the shoe upper.
