Description

A dust removal device for shoemaking

technical field

The invention relates to the field of shoe-making equipment, in particular to a shoe-making dust removal device.

Background technique

In the manufacturing process of leather shoes, leather polishing is an essential process. However, due to static electricity during grinding, more dust will remain on the leather, and the dust on the leather needs to be removed before further processing. The existing leather dedusting device generally cleans the leather surface directly through the air blowing pipe, which easily causes the leather dust to fly, resulting in secondary pollution, and the dedusting efficiency is extremely low and consumes energy.

In order to solve the problem of low efficiency of the existing leather dust removal device, the Chinese invention patent application CN104475404A discloses a leather dust removal device, which includes a conveyor belt and a symmetrical dust removal mechanism. The dust removal mechanism includes a fixed box, a support wheel, a positive pressure Fan and negative pressure fan, the support wheels are symmetrically arranged on both sides of the fixed box, the fixed box is provided with double-layer pipes, the inner pipe of the double-layer pipe is connected with the positive pressure fan, and the outer pipe is connected with the negative pressure fan Connection, a dust removal brush is arranged between the outer pipe and the inner pipe, the dust removal brush is connected with the fixed box through a spring rod, and the diameter of the bottom of the inner pipe is one-tenth of the inner pipe. The device can effectively improve the dust removal efficiency of leather, but its structure is complex and its performance is unstable. First of all, the fixed boxes of the dust removal mechanism must be located on both sides of the conveyor belt, which makes the device must be provided with other support mechanisms above the leather to fix the fixed boxes. In addition, the fixed box not only drives the dust removal brush to rotate, but also has the function of fixing the outer pipe and inner pipe, so the movement of the dust removal brush will easily cause the outer pipe and inner pipe to shake, resulting in misalignment of the bottom of the outer pipe and inner pipe, affecting the dust removal effect .

Chinese invention patent application CN105018653A discloses a kind of leather dedusting machine, and it comprises jet pipe, air chamber, cloth bag dust filter, clean air outlet, dust suction port, leather conveyor belt, vibrating motor, is provided with dust suction port on the leather conveyor belt, dust suction There is an air jet port in the center of the mouth, and the air jet port is set at the end of the air jet pipe. The air jet pipe is connected to the clean air outlet through the blower. There is an air chamber above the dust suction port. The air chamber is equipped with a suction fan and a bag filter. A clean air outlet is provided, and a vibrating motor for shaking off dander on the leather is provided under the belt of the leather conveyor belt. The air jet pipe and the dust suction pipe of the device are independent of the vibrating motor, which can overcome the problem that the air jet pipe and the dust suction pipe are easy to appear due to the movement of the air jet pipe and the dust suction pipe and the dust removal brush mentioned in the Chinese invention patent application CN104475404A. Misalignment problem, but the cleaning effect of the vibrating device on dust is weaker than that of the dust removal brush.

Chinese utility model CN205501328U discloses a kind of leather dedusting machine, and Chinese invention patent application CN103361446A also discloses a kind of leather dedusting machine, and their dedusting mechanisms are all located on the upper and lower sides of the conveyor belt, and its structure is simpler than CNCN104475404A and CN105018653A, and there are also CNCN104475404A and The technical defect existing in CN105018653A, for example CN205501328U only has blowing unit and dust-absorbing unit, dust removal efficiency is low, and the bristle roller and air suction port of CN103361446A are all positioned at one end of dust removal box body, and the movement of brush hair roller easily causes the dislocation of suction air port, and its lack With the aid of blowing, the dust removal efficiency is low.

This shows that the dedusting effect of existing leather dedusting device is all unsatisfactory.

Contents of the invention

The present invention aims to provide a dust removal device for shoemaking with good dust removal effect to replace the existing leather dust removal equipment and solve the technical problems of low efficiency and unstable dust removal effect in the existing leather dust removal equipment.

In order to achieve the above object, the present invention adopts following technical scheme:

A dust removal device for shoemaking, comprising a conveyor belt, a dust removal brush, a positive pressure fan and a negative pressure fan, an air outlet and an air suction outlet, leather is transported on the conveyor belt, the dust removal brush is located on the upper and lower sides of the leather, and the The blowing port is connected to the positive pressure fan, the air suction port is connected to the negative pressure fan, and the blowing port and the suction port are respectively located on the left and right sides of the leather.

As an improved technical solution of the present invention, the vertical distribution range of the air outlet is equal to the distance between the bristle roots of the upper and lower dust removal brushes, and the vertical distribution range of the air suction port is greater than the distance between the bristle roots of the upper and lower dust removal brushes. distance between.

As an improved technical solution of the present invention, the air outlet is divided into a plurality of small air outlets and arranged in an array, and the small air outlets are in the shape of sharp beaks.

Further, the air outlet directions of the small air outlets all face the leather.

As an improved technical solution of the present invention, the air suction port is connected to the air suction hood, the air suction hood is connected to the air suction pipe, the diameter of the air suction hood at the air suction port is large, and the diameter of the air suction hood at the suction pipe is large. small.

Further, the suction hood is a baffle located on the upper and lower sides of the leather, and holes are provided at the place where the baffle corresponds to the dust removal brush. The bristles of the dust removal brush are located between the leather and the baffle, and the dust removal brush The brush handle passes through the hole and is connected with the dust removal brush driving device on the upper and lower sides of the baffle plate.

Further, the baffle is provided with a dust shield bent towards the leather direction on the three edges of the non-air suction opening.

As an improved technical solution of the present invention, the air outlet of the negative pressure fan leads to an open water storage tank, and the air outlet is lower than the water surface in the water storage tank.

Further, the cross section of the water storage tank is a right-angled trapezoid, the bottom of the water storage tank is the upper bottom of the trapezoid, and the air outlet is located on the hypotenuse side of the trapezoid.

Further, the water storage pool is set outside the shoe factory.

Beneficial effect:

Compared with the existing leather dust remover, the invention has simple structure and stable dust removal effect. In addition, the suction hood of the present invention almost completely wraps the leather, avoiding the dust raised by the dust removal brush and the positive pressure fan, and avoiding the secondary pollution caused by the dust on the leather; the negative pressure fan collects the dust and transports it to the storage area. In the pool, the dust comes into contact with the water body, deposits at the bottom of the pool, and clean air overflows from the water surface. As a result, there is no dust flying in the entire shoe factory, and the office environment has been greatly improved.
