Description

Technical Field

[0001] This utility model relates to the field of bag brushing machine technology, and in particular to a dust collection device for bag brushing machines. Background Technology

[0002] A bag cleaning machine is a specialized device for cleaning flexible packaging bags. It removes oil and other impurities from the bags using a built-in spiral brush system and a circulating water spray system. Bag cleaning machines can also be customized to meet specific processing requirements.

[0003] In order to reduce production costs by using recycled bags, the dust on the bags needs to be cleaned in practice. The conventional cleaning method is pulse dust removal. However, pulse dust removal is effective for local dust removal, but the pulse airflow is difficult to reach the entire bag. In addition, some bags have good airtightness and very small air vents. The high-pressure airflow generated by the pulse not only fails to remove the dust inside the bag, but also easily tears the bag. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a dust collection device for a bag brushing machine, which overcomes the shortcomings of the prior art and effectively solves the problems of incomplete pulse dust removal and easy bag tearing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dust collection device for a bag-brushing machine includes a dust collection bin, inside which a dust collection chamber is provided. A servo motor is installed on one side of the dust collection bin. The output shaft of the servo motor is fixedly connected to a disc, and a connecting rod is rotatably connected to the outer wall of one side of the disc. A long rod is hinged to the outer wall of one end of the connecting rod, and a rack is welded to the top outer wall of the long rod. A gear meshes with the outer wall of the rack, and a ventilation main pipe is fixedly connected to the inner wall of the gear. A fixing clamp is fixedly connected to the bottom outer wall of the ventilation main pipe by a rope.

[0007] The outer wall of the bottom of the main ventilation pipe is welded with a ventilation branch pipe, and the outer wall of the ventilation branch pipe is provided with an external air outlet and an internal air outlet. An air inlet hose is fixedly connected to the outer wall of one end of the main ventilation pipe, and a first blower is installed on the outer wall of one end of the air inlet hose.

[0008] Preferably, the inner wall of the fixing clip is fixedly connected to the bag, and the outer wall of one end of the ventilation branch pipe is set inside the bag.

[0009] Preferably, the inner wall of one side of the dust collection bin is fixedly connected with symmetrically distributed sliding sleeves, and the long rod is slidably connected to the inner wall of the sliding sleeves.

[0010] Preferably, a fan is fixedly connected to the top outer wall of the dust collection bin by bolts.

[0011] Preferably, a dust collection hopper is fixedly connected to the inner wall of the bottom of the dust collection bin, and a dust collection pipe is fixedly connected to the outer wall of the bottom of the dust collection hopper. A second blower is installed on the outer wall of the dust collection pipe. The second blower is connected to a dust collection box through the dust collection pipe. A dust collector bag is fixedly connected to the outer wall of one side of the dust collection box.

[0012] Preferably, a fixing frame is welded to one side of the outer wall of the dust collection bin, and the servo motor is fixedly connected to the bottom inner wall of the fixing frame by bolts.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The dust collection device for the bag brushing machine designed in this paper can be used to fix the bag to the bottom of the ventilation pipe. The servo motor drives the disc to rotate, and the rack on the long rod can control the gear to rotate back and forth, so that the ventilation pipe is in a state of constant oscillation, which has the effect of vibration dust removal. Compared with pulse dust removal, the dust removal is more comprehensive and the dust removal effect is better.

[0015] 2. The dust collection device for the bag brushing machine in this design adds an inner and outer wall cleaning structure. During the vibration of the bag, the first blower can blow airflow along the air inlet hose and the main air outlet into the air outlet branch pipe. The out outlet and inner outlet on the air outlet branch pipe can clean the outer and inner walls of the bag respectively, which has the advantage of good internal filtration effect and also avoids the high-pressure airflow from breaking the bag.
