Description

Technical Field

[0001] The utility model relates to the technical field of stretch film raw material production, in particular to a blanking mechanism for stretch film raw material production. Background Technique

[0002] After retrieval, a blanking mechanism for stretch film raw material production with the publication number of CN218399016U belongs to the technical field of stretch film raw material production, including a blanking tank, a feeding pipe welded to one side of the top wall of the blanking tank, and a discharge pipe welded to the center of the bottom wall of the blanking tank. A protruding plate is fixedly welded to the bottom of the outer wall of the discharge pipe, and a U-shaped placing seat is welded to the bottom wall of the protruding plate. A first motor is welded to the outer wall of the placing seat, and an inner support shaft is rotatably connected to the inside of the placing seat. The output shaft of the first motor is coaxially connected to the inner support shaft. A closing flap is fixedly sleeved on the inner support shaft, and an inner sealing plate is fixedly adhered to the top wall of the closing flap. A second motor is welded to the center of the top wall of the blanking tank. For this blanking mechanism for stretch film raw material production, the amount of stretch film raw material particles in each batch is almost the same, making the quality of the stretch film produced in each batch more uniform.

[0003] The quantitative device of the above equipment is arranged at the discharge port, and this quantitative device is triggered by a fixed-time cycle. If the raw materials are uneven during feeding, it will cause a large difference in the quantity of raw materials in the barrel at different time periods, and it is difficult to guarantee the quantity of the final discharge. Moreover, this equipment cannot adjust the size of the discharge port according to actual usage requirements. If the agglomerates are small, they will directly pass through the crushing frustum, and the discharge quality cannot be guaranteed. Therefore, a blanking mechanism for stretch film raw material production is needed to meet people's needs. Content of the Utility Model

[0004] The purpose of the utility model is to provide a blanking mechanism for stretch film raw material production to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A blanking mechanism for stretch film raw material production, including a blanking device main body and a feed hopper installed on the blanking device main body; the blanking mechanism further includes a feed plate, a first spring, a first rotating shaft, a crushing wheel, a first push rod, a steel plate, and a screening net. The feed plate is installed in the feed hopper, the first spring is installed below the feed plate, the first rotating shaft is installed inside the blanking device main body, the crushing wheel is installed on the first rotating shaft, the first push rod is installed on one side of the blanking device main body, the steel plate is installed on the first push rod, the screening net is installed below the blanking device main body, and support legs are installed below the blanking device main body.

[0006] Preferably, a feed shaft is installed in the feed hopper, the feed plate is installed on the feed shaft, one end of the first spring is connected to the lower surface of the feed plate, and the other end of the first spring is connected to the inner wall of the feed hopper.

[0007] Preferably, a working cavity is formed in the main body of the blanking device, and the steel plate and the crushing wheel are both installed in the working cavity.

[0008] Preferably, a first motor is installed on one side of the main body of the blanking device, the first rotating shaft is installed on the first motor, and a first stop block is installed on the crushing wheel.

[0009] Preferably, a second motor is installed on one side of the main body of the blanking device, the first push rod is installed on the second motor, and a second stop block is installed on the steel plate.

[0010] Preferably, a fixing bolt is installed on one side of the main body of the blanking device close to the second motor, and one end of the fixing bolt is in contact with one side of the steel plate.

[0011] Preferably, a vibration motor is installed on the screening net, and screening holes are formed in the screening net.

[0012] Preferably, a first collection box is installed below the screening net, and a second collection box is installed on one side of the screening net.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] (1) In the present utility model, the first rotating shaft is driven to rotate by the first motor. When the first rotating shaft rotates, the crushing wheel is driven to rotate. When the raw materials fall into the gap between the crushing wheel and the steel plate, the caked raw materials will be crushed by the extrusion of the crushing wheel and the steel plate. The crushed raw materials fall onto the screening net. The first push rod is pushed by the second motor, and the first push rod pushes the steel plate, so that the distance between the steel plate and the crushing wheel can be adjusted, and the smaller caked materials can be crushed according to requirements.

[0015] (2) Feeding is carried out through the feed hopper. During feeding, the raw materials are stacked on the feed plate. When the weight of the raw materials on the feed plate is greater than the weight that the first spring can support, the raw materials on the feed plate press down the first spring, and the feed plate rotates downward on the feed shaft, so that the raw materials fall into the main body of the blanking device. The weight of each feeding can be controlled, avoiding too much or too little feeding from affecting the blanking quantity. Since the feeding quantity per time is fixed, the discharging quantity per time can be guaranteed to be fixed.

[0016] (3) The crushed raw materials will fall onto the screening net. The vibration motor drives the screening net to vibrate. The raw materials smaller than the screening holes will fall into the first collection box for use, and the larger caked materials will fall into the second collection box on the lower side of the screening net under the action of vibration and gravity, which is convenient for subsequent adjustment of the steel plate for secondary crushing.

[0024] In order to achieve the function of adjustable discharge size, a working cavity 7 is opened in the feeding device main body 1.

After the raw materials enter the feeding device main body 1, the first motor 8 drives the first rotating shaft 9 to rotate. When the first rotating shaft 9 rotates, it drives the crushing wheel 10 to rotate. The raw materials will fall into the gap between the crushing wheel 10 and the steel plate 14, and the caked raw materials will be crushed by the extrusion of the crushing wheel 10 and the steel plate 14.
