Description

Technical Field

[0001] The utility model belongs to the technical field of bag-making machine punching, and particularly relates to a negative pressure collection device for punched corner materials of a bag-making machine. Background Art

[0002] The punching scraps of bag making machine refer to the waste scraps generated when a punching machine is used to punch holes (such as ventilation holes, hook holes, etc.) in plastic film or other materials during the bag making process. These scraps are usually fragments cut from the raw materials due to the punching operation. The negative pressure collection device for the punching scraps of bag making machine is a system for automatically processing these waste scraps. It uses negative pressure (i.e. vacuum suction) to suck the small fragments and dust generated in the punching process into a dust collection box or collection container. This design helps to keep the working environment clean, reduce waste, and improve production efficiency.

[0003] The existing negative pressure collection device for punched scraps of bag making machines collects the scraps into a collection box through negative pressure, and filters the dust in the air through a filter plate arranged at the lower end of the collection box to extend the service life of the collection device. The filter plate cannot automatically clean the dust collected thereon, and the filter plate needs to be manually cleaned regularly, which increases the time and cost of manual maintenance. As dust accumulates on the filter plate, air circulation is blocked and the negative pressure effect is weakened, which may lead to a decrease in collection efficiency and even affect the normal operation of the bag making machine. Utility Model Content

[0004] In view of this, the utility model aims to solve the shortcomings of the prior art and provide a negative pressure collection device for punched scraps of a bag making machine. Automatic cleaning can continuously keep the filter plate clean, ensure that the negative pressure system is always in the best working condition, improve overall production efficiency, reduce the frequency of manual intervention, and reduce maintenance costs and downtime.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a negative pressure collection device for punched scraps of bag making machine, including a box body, a collection box is slidably arranged inside the box body, a handle is arranged on the front side of the collection box, two spring plates are rotatably connected to the front side of the box body, and the two spring plates are installed in cooperation with a collection box, a filter plate located at the lower end of the collection box is also slidably arranged inside the box body, a handle is arranged on the front side of the filter plate, a fan is also arranged on the bottom wall of the box body, a plurality of air outlet slots are opened at the lower end of the interior of the box body, a self-cleaning mechanism for self-cleaning the filter plate is arranged on the front side of the box body, a cleaning and collecting mechanism is arranged on the rear side of the box body, the self-cleaning mechanism includes a slide rail arranged inside the installation opening opened on the front side of the box body, and the slide rail The inner sliding part is provided with a rotating frame, the inner rotating part of the rotating frame is connected with a connecting frame, the inner sliding part of the box body is provided with a scraper installed in cooperation with the filter plate, the front side of the scraper is provided with a rotating seat, the rear end of the connecting frame is connected with the inner rotation of the rotating seat, the inner rotation of the slide rail is provided with a screw rod, the rotating frame is threadedly connected with the screw rod, and the left side of the slide rail is provided with an electric drive unit for driving the screw rod to rotate, the electric drive unit includes a motor arranged on the left side of the slide rail, and the output shaft of the motor is connected with the left end of the screw rod through a coupling, the cleaning and collecting mechanism includes an electric push rod arranged on the rear side of the box body, a sealing plate is arranged on the telescopic end of the electric push rod, a notch installed in cooperation with the sealing plate is opened on the rear side of the box body, and a collection frame installed in cooperation with the notch is arranged on the rear side of the box body.

[0006] As a further improvement of the present invention, a control panel is provided on the front side of the box body, and the motor, the fan and the electric push rod are all electrically connected to the control panel.

[0008] As a further improvement of the utility model, a plurality of mounting holes are provided at the upper end of the box body.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] Firstly, the box body can be installed at a suitable position of the bag making machine through the mounting hole, and then the operation of the fan can be controlled through the control panel. The rotation of the impeller generates negative pressure, which can suck the scraps generated during punching into the interior of the collection box to collect the scraps. At the same time, the air passing through the collection box passes through the filter plate to filter impurities in the air, which can prevent dust accumulation on the fan from affecting its normal operation. After the collection is completed, the spring pieces on both sides are pulled up and rotated to make them leave the front side of the collection box, and the collection box can be pulled out by handle one, so that the scraps inside can be processed, making the negative pressure collection efficiency higher.

[0011] Secondly, the control panel is used to control the electric push rod to operate, and the telescopic end drives the sealing plate to move upward to expose the notch. Then the control panel is used to control the motor to operate, and the output shaft drives the screw to rotate, so that the rotating frame moves to the left, and the connecting frame inside it rotates and expands, so that the scraper on the rotating seat moves backward to scrape off the impurities on the filter plate. The scraper continues to move backward and can push the scraped dust into the collection frame through the notch, thereby realizing self-cleaning collection of the filter plate. Automatic cleaning can continuously keep the filter plate clean, ensuring that the negative pressure system is always in the best working condition, improving overall production efficiency, reducing the frequency of manual intervention, and reducing maintenance costs and downtime.

[0012] Thirdly, the supporting mounting plate can realize stable support for the negative pressure collection device, making the operation of the negative pressure collection device more stable.

[0013] Fourthly, the control panel allows personnel to quickly control the electrical components on the negative pressure collection device. BRIEF DESCRIPTION OF THE DRAWINGS
