Description

Technical Field

[0001] This invention relates to the field of shoemaking equipment, and in particular to a dust removal device and method for finished shoes. Background Technology

[0002] In the shoe manufacturing process, a large amount of dust is generated in multiple stages, from sole grinding to upper cutting. This dust not only adheres to the surface of the shoe but also penetrates into hidden areas such as crevices, toes, and heels. Existing shoe dust removal equipment typically uses a work platform as its core, with a negative pressure chamber inside. Several suction holes connected to the negative pressure chamber are distributed on the platform. A motor in the bottom fan duct drives the fan blades to create negative pressure, sucking dust from the shoe surface into the equipment. To achieve dust collection, a ring pipe is connected to the lower end of the fan duct. A water pump draws water from the dust collection box, which forms a water curtain through a vertical downward first water spray hole and an inclined upward second water spray hole on the ring pipe. This water curtain washes and settles the sucked-in dust, and the purified air is discharged from the exhaust ducts on both sides of the dust collection box. However, the dust removal range of such equipment is limited: its negative pressure suction structure can only act on the outer surface of the shoe. As for residual dust in the creases, edges of the shoe opening and internal cavities, the airflow cannot effectively penetrate and completely remove it, which may result in the finished shoes still having internal dust accumulation problems, affecting the cleanliness of the product. Summary of the Invention

[0003] The purpose of this invention is to provide a dust removal device and method for finished shoes. This invention uses a movable, curved inner suction tube to remove dust from inside the shoe, thus improving the dust removal efficiency.

[0010] The aforementioned dust removal method for finished shoe dust removal equipment involves the following steps: First, the shoes are conveyed to the top of the dust collection box via a conveying mechanism. The dust collection mechanism is then activated, and the dust on the soles of the shoes enters the dust collection mechanism through the dust collection box. Simultaneously, suction is generated in the inner suction tube, which is in an upright position and first absorbs the dust on the shoe surface. Next, the lifting cylinder is activated, bringing the inner suction tube into the shoe body to absorb the dust inside the shoe. Then, the bending cylinder is activated, and the movable seat moves laterally, causing the movable elastic wheel to press the inner suction tube. The crossbar bends the end of the inner suction tube, with the suction head of the inner suction tube facing the inside of the shoe body, effectively removing the dust from the inside of the shoe body.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, the shoe is conveyed to the top of the dust collection box via a conveying mechanism. The dust collection mechanism is activated, and the dust on the sole of the shoe enters the dust collection mechanism through the dust collection box. At the same time, suction is generated in the inner suction tube. The inner suction tube is in an upright state and first absorbs the dust on the shoe surface. Then, the lifting cylinder is activated to bring the inner suction tube into the shoe body to absorb the dust inside the shoe body. Next, the bending cylinder is activated, the movable seat moves laterally, and drives the movable elastic wheel to press the inner suction tube. The crossbar bends the end of the inner suction tube, and the suction head of the inner suction tube faces the inside of the shoe body. The dust inside the shoe body is sucked out through the movable and bent inner suction tube, improving the dust collection effect.

[0012] 2. The side of the dust collection box is equipped with multiple dust outlet pipes. The dust collected enters the collection box through multiple dust outlet pipes, improving dust collection efficiency. Compared with a single dust outlet, the multi-hole dust outlet structure avoids clogging.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0017] Example: Dust removal equipment for finished shoes, including a conveying mechanism 1, as shown in the attached diagram. Figure 1 As shown, a top support 2 is fixed on the conveying mechanism 1, and a dust collection box 3 connected to the dust collection mechanism is installed at the lower part of the conveying mechanism 1. The conveying mechanism 1 includes a main frame 17, on which a conveyor belt 18 is installed. The conveyor belt 18 has multiple round holes 19. The dust collection box 3 is located on the upper part of the main frame 17, and the round holes 19 correspond to the inlet end of the dust collection box 3. The dust collection mechanism includes a storage box, the outlet end of which is connected to a blower, and the inlet end of the blower is connected to a pipe. The side of the dust collection box 3 has multiple dust outlet pipes 31 connected to the dust collection mechanism. Dust from the bottom of the shoe falls into the dust collection box through the round holes. The adsorbed dust enters the collection box through the multiple dust outlet pipes, improving dust collection efficiency. Compared with a single dust outlet, the multi-hole dust outlet structure avoids clogging.

[0018] The side of the vacuum box 3 is connected to an inner suction tube 4 for vacuuming the inside of the shoe; the top support 2 has a top space 5 at its upper end, as shown in the attached figure. Figure 2As shown, a lifting support 6 is installed in the top space 5. Lifting cylinders 7 are installed at both ends of the lifting support 6. The extended ends of the lifting cylinders 7 are connected to a fixed main plate 8. The lifting cylinders can drive the fixed plate to rise and fall, and mainly control the up-and-down movement of the inner suction tube. A bending cylinder 9 is installed on the main surface of the fixed main plate 8. A limit frame 10 is also installed on the main surface of the fixed main plate 8. A movable seat 11 is slidably installed on the limit frame 10. Multiple rollers 25 are installed on the side of the movable seat 11. The upper end of the limit frame 10 has a guide rail 26 that matches the rollers 25. The movable seat rotates on the guide rail via the rollers. The movement of the movable frame is relatively smooth through the roller structure. The movable seat 11 has a movable elastic wheel 12 that fits against the inner suction tube 4, as shown in the attached figure. Figure 3 and 4 As shown, the lower end of the movable seat 11 is provided with a crossbar 13 for bending the inner suction tube 4; the end of the limiting frame 10 is equipped with a guide bracket 14, and the inner side of the guide bracket 14 is equipped with a fixed wheel 15 for engaging the inner suction tube 4. The fixed wheel and the movable elastic wheel clamp and fix the inner suction tube. The inner side of the bracket at the upper end of the movable seat has an inner groove, and a spring is in the inner groove. The main shaft of the movable elastic wheel is connected to the spring. When the movable seat moves toward the fixed wheel, the spring is compressed. As the movable seat moves, the movable elastic wheel moves accordingly. The extended end of the bending cylinder 9 is connected to a thrust member 16 via a hinge. One end of the thrust member 16 is hinged to the fixed main plate 8, and the other end of the thrust member 16 is hinged to one end of the movable seat 11. After the extended end of the bending cylinder extends downward, it will drive the thrust member to move. During the downward movement of the thrust member, the movable seat will move.

[0019] The limiting frame 10 has cylinder frames 20 installed on both sides. A shoe clamping cylinder 21 is installed at the end of each cylinder frame 20. A clamping block 22 is installed at the extended end of the shoe clamping cylinder 21. The clamping block 22 has a groove 23, and multiple movable clamping blocks 24 are installed within the groove 23. The shoe clamping cylinder can securely clamp the shoe, facilitating dust removal from the shoe surface. Since the side of the shoe is curved, if the clamping end of the cylinder were flat, the clamping stability would be poor. Therefore, movable clamping blocks are used to clamp the shoe. The guide bracket 14 has a connecting sleeve 27 at its end. The end of the limiting frame 10 is embedded in the connecting sleeve 27, and the limiting frame 10 is connected to the connecting sleeve 27 by bolts, making installation convenient and quick.

[0020] The working principle of this invention: The shoe is conveyed to the top of the vacuum box via the conveying mechanism. The vacuuming mechanism is activated, and the dust on the sole of the shoe enters the vacuuming mechanism through the vacuum box. At the same time, suction is generated in the inner suction tube. The inner suction tube is in an upright state and first absorbs the dust on the shoe surface. Then, the lifting cylinder is activated, bringing the inner suction tube into the shoe body to absorb the dust inside the shoe. Next, the bending cylinder is activated, the movable seat moves laterally, and drives the movable elastic wheel to press the inner suction tube. The crossbar bends the end of the inner suction tube, and the suction head of the inner suction tube faces the inside of the shoe body. The dust inside the shoe body is sucked out through the movable and bent inner suction tube, improving the vacuuming effect.
