[0002] During the production process of the filter material of the bag filter, it is necessary to trim the edges to ensure that the filter material has a specified width. After trimming, the trimmed strips are difficult to recycle because they have been processed by needle punching, calendering, hydrophobicity, etc. They are generally discarded in a centralized manner. This results in a waste of filter material and makes the production cost of the filter cloth too high. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a device for recycling filter material trimming strips, which can automatically feed and then break up the trimming strips to form fluffy filter material, which is convenient for adding to the raw materials for filter cloth molding.

[0005] As a preferred solution, the feeding rack includes a feeding trough arranged obliquely, the lower end of the feeding trough is connected to the upstream cavity wall of the recovery chamber, an upper pressure rod is arranged at the downstream end of the feeding trough, and a feeding port is formed between the upper pressure rod and the bottom of the feeding trough.

[0006] As a preferred solution, the feeding roller is located in the recovery chamber and close to the upper end of the upstream chamber wall, and a feeding channel is formed between the feeding roller and the upstream chamber wall.

[0007] As a preferred solution, the barbs on the scattering roller and the barbs on the feeding roller are staggered, and the scattering roller and the feeding roller rotate in the same direction.

[0008] As a preferred solution, the upper cover shell is hinged at the upper end of the downstream side wall of the recovery chamber, and an arc-shaped cover shell portion is provided on the upper cover shell, and the arc-shaped cover shell portion covers the breaking up roller and the feeding roller, and the air inlet is provided on the two side plates of the arc-shaped cover shell portion.

[0009] As a preferred solution, an arc-shaped baffle is further provided inside the arc-shaped cover shell portion, and an arc-shaped air inlet channel is formed between the arc-shaped baffle and the arc-shaped cover shell portion. The arc-shaped air inlet channel is connected to the air inlet, and the air outlet position of the arc-shaped air inlet channel is aligned with the matching position of the breaking up roller and the feeding roller.

[0010] After adopting the above technical scheme, the effect of the present invention is as follows: since the filter material trimming strip recycling and reuse device includes a machine base, a recovery chamber is arranged on the machine base, the upper end of the recovery chamber is open, the upper opening of the recovery chamber is hinged with an upper cover shell, the upper cover shell is provided with an air inlet, the upstream side cavity wall of the recovery chamber is inclined, a feeding rack is arranged on the machine base at the upstream side of the recovery chamber, a feeding roller is rotatably installed on the machine base, the feeding roller corresponds to the upper end position of the upstream side cavity wall of the recovery chamber and is driven by a feeding rotating power device, a scattering roller is also rotatably installed in the recovery chamber, and the scattering roller is driven by a scattering rotating power device The power device drives the scattering roller and the feeding roller, and the surfaces of the scattering roller are provided with a plurality of hooks for hooking the filter material trimming strips. The bottom of the recovery chamber is provided with a discharge port, and the discharge port is connected to a discharge fan. First, the feeding rotating power device drives the feeding roller to rotate, driving the filter material trimming strips on the feeding rack into the recovery chamber, and then the scattering power device drives the scattering roller to rotate, and further scatters the filter material trimming strips. Subsequently, the discharge fan exhausts air at the discharge port to take away the scattered filter material trimming strips. The recycling and reuse device can automatically feed the trimming strips and then scatter them, thereby forming fluffy filter material, which is convenient for adding to the raw materials for forming the filter cloth.

[0011] Furthermore, since the feeding rack includes a feeding trough that is inclined, the lower end of the feeding trough is connected to the upstream wall of the recovery chamber, and an upper pressure rod is provided at the downstream end of the feeding trough, and a feeding port is formed between the upper pressure rod and the bottom of the feeding trough; the feeding trough can ensure that the filter material cutting strips are accurately placed in the feeding trough during transportation, and then cooperate with the upper pressure rod to ensure that the filter material cutting strips are accurately output.

[0012] Furthermore, since the feeding roller is located in the recovery chamber and close to the upper end of the upstream chamber wall, a feeding channel is formed between the feeding roller and the upstream chamber wall, so that the filter material trimming strips delivered from the feeding port can quickly and accurately enter the feeding channel for transportation, thereby ensuring the transportation and breaking up efficiency.

[0013] Furthermore, since the barbs on the scattering roller are interlaced with the barbs on the feeding roller, the scattering roller and the feeding roller rotate in the same direction; when the feeding roller and the scattering roller are scattering, some fluffy filter materials will be carried on their surfaces, and the scattering roller can effectively take away the filter materials on the feeding roller, while the feeding roller can also take away the filter materials on the scattering roller, and the filter materials wound on the surfaces of the scattering roller and the feeding roller are cleaned from each other, thereby improving the use effect.

[0014] Since the upper cover shell is hinged at the upper end of the downstream side wall of the recovery chamber, an arc-shaped cover shell portion is provided on the upper cover shell, and the arc-shaped cover shell portion covers the breaking up roller and the feeding roller, and the air inlets are provided on the two side plates of the arc-shaped cover shell portion, which effectively shields the recovery chamber to prevent the broken up filter material from flying out and affecting the external environment.

[0015] Since an arc-shaped baffle is also provided inside the arc-shaped cover shell portion, an arc-shaped air inlet channel is formed between the arc-shaped baffle and the arc-shaped cover shell portion, and the arc-shaped air inlet channel is connected to the air inlet, and the air outlet position of the arc-shaped air inlet channel is aligned with the matching position of the scattering roller and the feeding roller; in this way, when the discharging fan exhausts air in the recovery chamber through the discharging port, the airflow entering from the air inlet can enter the recovery chamber from between the scattering roller and the feeding roller along the arc-shaped air inlet channel, which can effectively drive the scattered filter material to accurately enter the discharging port, avoid the scattering of the filter material, and improve the use effect.
