Description

Technical Field

[0001] This utility model relates to the field of shoe manufacturing technology, and in particular to a coating equipment for the wear-resistant layer of work shoe soles. Background Technology

[0002] Safety shoes (work boots) are protective footwear specifically designed for high-risk working environments such as industry, construction, and mining. Their core function is to protect users from occupational injuries caused by falling objects, sharp object punctures, static electricity, and chemical corrosion. The sole, as the part of the safety shoe in direct contact with the ground, directly affects the shoe's lifespan and protective effect due to its abrasion resistance. Statistics show that in heavy industry or construction sites, sole wear is one of the main reasons for premature wear and tear on safety shoes; therefore, optimizing the performance of the abrasion-resistant layer has become a key focus of industry technological research.

[0003] Currently, the coating of abrasion-resistant layers on shoe soles mainly relies on manual spraying. Operators use spray guns to apply abrasion-resistant coatings (such as polyurea and silicon carbide composite materials) to specific parts of the sole. This method is highly flexible, but manual spraying is labor-intensive, and the freshly coated material does not solidify quickly, so the shoes need to be turned upside down, which reduces operational efficiency. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a coating device for the wear-resistant layer of work shoes soles.

[0005] The technical solution of this utility model is a coating equipment for the wear-resistant layer of work shoes soles, including a frame, a turntable, an arc guide plate, a pad, a coating mechanism, and multiple sets of automatic clamping components;

[0006] The turntable is mounted on top of a frame, on which a servo motor is installed to drive its rotation. The turntable has multiple sets of placement holes, including left and right shoe placement holes. Fixed clamps are fixedly installed on the inner walls of both left and right shoe placement holes, and movable clamps are movably installed on the inner sides of both holes. The turntable also has multiple connecting holes, which correspond one-to-one with the automatic clamping components and the sets of placement holes. The connecting holes communicate with the corresponding left and right shoe placement holes. The automatic clamping components include a push rod, an L-shaped connecting slider, a guide rod, a spring, and a connecting rod. Two sliders, two springs, and two connecting rods are provided. Both ends of the guide rod are fixedly connected to the inner wall of the connecting hole. The two L-shaped connecting sliders are slidably mounted on the guide rod and are respectively connected to the movable clamps on both sides. The two springs are respectively sleeved on both ends of the guide rod. The push rod moves through the side of the turntable and its inner end is located in the connecting hole. The two connecting rods are rotatably mounted on the inner end of the push rod. The other ends of the two connecting rods are rotatably connected to the two L-shaped connecting sliders respectively. The arc-shaped guide plate is located on the outer periphery of the turntable and is fixedly connected to the frame. The main body of the arc-shaped guide plate is distributed along a circular path, and one end of it deviates from the circular path and bends outward. The coating mechanism is located at the upper end of the frame. The pad is located on the frame.

[0007] Preferably, the coating mechanism includes a paint tank, a drive motor, and a roller. The paint tank is mounted on the frame, the roller is rotatably mounted on the upper inner side of the paint tank, and the drive motor is mounted on the paint tank with its output shaft connected to the rotating shaft of the roller.

[0008] Preferably, the roller is a soft-bristled roller.

[0009] Preferably, a drying mechanism is installed on the frame. The drying mechanism includes a hot air blower and a nozzle. Both the hot air blower and the nozzle are installed on the frame, and the output end of the hot air blower is connected to the nozzle by a pipe.

[0010] Preferably, a belt conveyor is provided on one side of the bottom of the turntable.

[0020] Example 1

[0021] like Figures 1-5 As shown in the figure, the workwear shoe sole abrasion-resistant coating equipment proposed in this embodiment includes a frame 1, a turntable 2, an arc-shaped guide plate 7, a pad 19, a coating mechanism, and multiple sets of automatic clamping components.

[0022] The turntable 2 is rotatably mounted above the frame 1. A servo motor 8 for driving the turntable 2 to rotate is mounted on the frame 1. The turntable 2 has multiple sets of placement holes arranged in a circular array. The placement hole sets include a left shoe placement hole 201 and a right shoe placement hole 202. A fixing clamp 12 is fixedly installed on the inner wall of the left shoe placement hole 201 and the right shoe placement hole 202. A movable clamp 13 is movably arranged on the inner side of the left shoe placement hole 201 and the right shoe placement hole 202. The turntable 2 has multiple connecting holes 203. The multiple connecting holes 203, the multiple sets of automatic clamping components, and the multiple sets of placement holes are all one-to-one. The connecting holes 203 are connected to the left shoe placement hole 201 and the right shoe placement hole 202 on the corresponding side.

[0023] The automatic clamping assembly includes a push rod 14, an L-shaped connecting slider 15, a guide rod 16, a spring 17, and a connecting rod 18. Two L-shaped connecting sliders 15, two springs 17, and two connecting rods 18 are provided. Both ends of the guide rod 16 are fixedly connected to the inner wall of the connecting hole 203. The two L-shaped connecting sliders 15 are slidably mounted on the guide rod 16 and connected to the movable clamping plates 13 on both sides respectively. The two springs 17 are respectively sleeved on both ends of the guide rod 16. The push rod 14 movably passes through the side of the turntable 2, and its inner end is located within the connecting hole 203. The two connecting rods 18 are rotatably mounted on the inner end of the push rod 14. The other ends of the two connecting rods 18 are rotatably connected to the two L-shaped connecting sliders 15 respectively. An arc-shaped guide plate 7 is located on the outer periphery of the turntable 2 and is fixedly connected to the frame 1. The main body of the arc-shaped guide plate 7 is distributed along a circular path, with one end deviating from the circular path and bending outwards. The coating mechanism is located at the upper end of the frame 1.

[0024] The pad 19 is set on the frame 1, and there is a gap between the pad 19 and the turntable 2. This setting ensures that the bottom of the shoe sole is below the turntable 2, preventing the shoe sole from being flush with the bottom surface of the turntable 2, thereby preventing the bottom surface of the turntable 2 from being coated with paint.

[0025] Furthermore, in this technical solution, a PLC controller 4 is installed on the rack 1, which is used to control the equipment.

[0026] In this embodiment, during operation, the left shoe and the right shoe are placed in the left shoe placement hole 201 and the right shoe placement hole 202 in the material placement area, respectively. The pad 19 is used to support the shoe sole. The turntable 2 is driven to rotate intermittently by the servo motor 8. The single rotation angle of the turntable 2 is 360 / N, where N is the number of placement hole groups.

[0027] When the outer end of the push rod 14 contacts the inner wall of the outwardly bent part on the arc-shaped guide plate 7, as the turntable 2 continues to rotate, the push rod 14 gradually moves inward under the limiting action of the arc-shaped guide plate 7. Under the cooperative work of the two connecting rods 18, the two L-shaped connecting sliders 15 are driven to move away from each other, which drives the two movable clamping plates 13 to move synchronously, thereby realizing the synchronous clamping work of the left and right shoes. When the shoes pass through the coating mechanism, the coating mechanism coats the wear-resistant coating onto the surface of the sole.

[0028] After the push rod 14 separates from the arc-shaped guide plate 7, the two L-shaped connecting sliders 15 are driven to automatically reset under the elastic force of the spring 17, which in turn drives the push rod 14 and the two movable clamps 13 to reset, thereby automatically releasing the fixation of the shoe and realizing the function of automatic unloading.

[0029] Example 2

[0030] like Figure 3As shown in this embodiment, a workwear shoe sole abrasion-resistant layer coating device is proposed. Compared with the first embodiment, in this embodiment, the coating mechanism includes a paint tank 9, a drive motor 10, and a roller 11. The paint tank 9 is set on the frame 1. The roller 11 is rotatably installed on the upper inner side of the paint tank 9. The drive motor 10 is installed on the paint tank 9 and its output shaft is connected to the rotating shaft of the roller 11. Starting the drive motor 10 can drive the roller 11 to rotate. During the rotation of the roller 11, the paint inside the paint tank 9 is filled with its surface. With rolling contact with the sole, the paint can be applied to the sole. The roller 11 is a soft-bristled roller. Since the sole is provided with anti-slip texture, the soft-bristled roller allows the paint to penetrate into the texture, thereby reducing coating dead angles.

[0031] Example 3

[0032] like Figure 1 As shown in the figure, the workwear shoe sole abrasion layer coating equipment proposed in this embodiment has a drying mechanism installed on the frame 1 compared to the first embodiment. The drying mechanism includes a hot air blower 5 and a nozzle 6. Both the hot air blower 5 and the nozzle 6 are installed on the frame 1. The output end of the hot air blower 5 is connected to the nozzle 6 by a pipe. After the hot air blower 5 is started, the hot air it generates enters the nozzle 6 through the pipe and is finally sprayed onto the sole through the nozzle 6, thereby accelerating the drying speed of the sole coating.

[0033] Example 4

[0034] like Figure 1 and Figure 2 As shown in the figure, the workwear shoe sole abrasion layer coating equipment proposed in this embodiment, compared with the first embodiment, has a belt conveyor 3 set on one side of the bottom of the turntable 2. The belt conveyor 3 is set in the automatic unloading area and is used to receive and transport the processed shoes.

[0035] Furthermore, a PLC controller 4 is installed on the rack 1 to control the equipment.

[0036] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
