Description

Technical Field

[0001] This utility model relates to the field of plastic film production technology, specifically to a mixing device for plastic film production. Background Technology

[0002] Plastic film is a thin, flexible sheet material made of synthetic polymers. It has many excellent properties such as transparency, chemical resistance, water resistance, and insulation, and is widely used in the packaging, agriculture, and construction industries. In the production of plastic film, in order to ensure the consistency of film thickness, color, and transparency, as well as to reduce uneven dispersion during extrusion and improve the efficiency of subsequent processing, a mixing device is usually used to premix raw materials such as colorants, additives, and solid base resins according to the formula ratio. Then, the mixed raw materials are put into the extruder and heated to melt. After that, they are quickly cooled and shaped by a cooling and shaping device, thus completing the production of plastic film.

[0003] However, existing plastic film mixing devices still have certain defects when in use. For example, after the premixing of raw materials such as colorants, additives and solid substrate resins is completed, the raw materials are still solid. During discharge, the solid raw materials are prone to clogging the discharge pipe of the mixing device. In addition, after the existing plastic film mixing device is fed, the solid raw materials in the mixing device are prone to local accumulation, which affects the mixing efficiency.

[0025] This application provides a mixing device for plastic film production. This mixing device, through the configuration of the feeding component, ensures that all components are fully mixed within the mixing device, avoiding uneven mixing caused by localized accumulation. Furthermore, the anti-clogging component effectively prevents outlet blockage, ensuring smooth material flow. The mixing device for plastic film production will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0026] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0027] Please see Figure 1-7 In this embodiment, a mixing device for producing plastic film is provided, comprising: a base 1, a mixing box 2 on the top of the base 1, and a feeding hopper 3 above the mixing box 2; a feeding component disposed between the base 1 and the feeding hopper 3 for improving the mixing effect, the feeding component including a dual-axis motor 203 and a turntable 204; and an anti-blocking component disposed inside the base 1 for preventing pipe blockage, the anti-blocking component including a push rod 405, a spring 402, a servo motor 4 and a cam 401.

[0028] Furthermore, during use, various raw materials are fed into the mixing chamber 201 through the feed hopper 3, and the dual-shaft motor 203 is started. The dual-shaft motor 203 drives the turntable 204 to rotate, so that the various raw materials falling onto the turntable 204 are scattered in all directions under the action of centrifugal force, so as to reduce the local accumulation of certain raw materials.

[0029] Furthermore, the servo motor 4 is activated to make the cam 401 continuously perform circular motion, and in conjunction with the spring 402, the connecting rod 403 drives the push rod 405 to move up and down reciprocally inside the discharge port 5, thereby loosening the material inside the discharge port 5 and reducing the possibility of blockage.

[0030] The base 1 has a limiting port 101 at the top, the mixing box 2 is located inside the limiting port 101, and the mixing box 2 has a limiting plate 102 on the outside; the mixing box 2 has a mixing chamber 201 inside, the top of the inner wall of the mixing chamber 201 has a fixing block 202, the fixing block 202 has a dual-axis motor 203 inside, the top of the dual-axis motor 203 is connected to a turntable 204 through a rotating shaft; the bottom of the dual-axis motor 203 is connected to multiple stirring paddles 205 through a rotating shaft, and the bottom of the dual-axis motor 203 is connected to two scrapers 206 through a rotating shaft.

[0031] In use, the dual-shaft motor 203 is started, which drives the turntable 204, stirring paddle 205 and scraper 206 to rotate. At this time, the raw materials falling to the top of the turntable 204 will be scattered in all directions under the action of centrifugal force, thereby reducing the local accumulation of certain raw materials after entering the mixing chamber 201. The rotating stirring paddle 205 and scraper 206 can mix the scattered raw materials, and the rotating scraper 206 can sweep the material inside the mixing chamber 201 into the discharge port 5, accelerating the discharge of materials.

[0032] The feed hopper 3 has a feed pipe 301 at the bottom and a magnet 304 at the top. The top of the magnet 304 is magnetically connected to an iron block 303. The top of the iron block 303 is covered with a cover plate 302. The magnet 304 and the iron block 303 are designed to seal the feed hopper 3 when the device is not in use, preventing external dust from entering the device.

[0033] The base 1 has an internal equipment cavity 103, which houses a servo motor 4. The servo motor 4 is connected to a cam 401 via a rotating shaft. The equipment cavity 103 also has a connecting rod 403, with a spring 402 sleeved on its outer side. The bottom of the base 1 has a discharge port 5, which houses a top rod 405. One side of the inner wall of the discharge port 5 has a positioning groove 501, and another side of the inner wall has a receiving groove 502. The base 1 also has an electric telescopic rod 6, with a sealing plate 601 fixedly connected to one end. A rubber block 602 is fixedly connected to the top of the sealing plate 601. The bottom end of the connecting rod 403 protrudes from the bottom of the mixing chamber 2 and is fixedly connected to a fixing rod 404. The bottom end of the top rod 405 is fixedly connected to the fixing rod 404. Through the electric telescopic rod 6, the sealing plate 601, and the rubber block 602, the discharge port 5 can be sealed to prevent the raw materials inside the mixing chamber 201 from leaking to the outside during mixing.

[0034] During the material discharge process, the operator can start the servo motor 4, which rotates the cam 401. This causes one end of the cam 401 to intermittently push the connecting rod 403 to compress the spring 402, causing the spring 402 to undergo elastic deformation. This causes the fixed rod 404 and the push rod 405 to move downwards. Then, through the elastically deformed spring 402, the connecting rod 403, the fixed rod 404, and the push rod 405 to move upwards. The servo motor 4 continuously causes the cam 401 to perform circular motion, which continuously causes the push rod 405 to move up and down reciprocally inside the discharge port 5, thereby loosening the material inside the discharge port 5 and reducing the possibility of blockage.

[0035] The working principle is as follows:

[0036] In use, pull the cover plate 302 to release the magnetic connection between the iron block 303 and the magnet 304, open the feed hopper 3, and pour all kinds of raw materials into the feed hopper 3. The raw materials fall through the feed pipe 301 to the top of the turntable 204. Then start the dual-shaft motor 203, which drives the turntable 204, the stirring paddle 205 and the scraper 206 to rotate. At this time, the raw materials falling to the top of the turntable 204 will be scattered in all directions under the action of centrifugal force, thereby reducing the local accumulation of certain raw materials after entering the mixing chamber 201. The rotating stirring paddle 205 and scraper 206 can mix the scattered raw materials.

[0037] Furthermore, after mixing is complete, the stirring paddle 205 and scraper 206 are kept rotating, and the electric telescopic rod 6 is controlled to move the sealing plate 601 into the receiving trough 502, so that the discharge port 5 is connected to the mixing chamber 201. At this time, the rotating scraper 206 will sweep the material inside the mixing chamber 201 into the discharge port 5, so that the raw material is discharged from the mixing chamber 201 through the discharge port 5. During the discharge process, the operator can start the servo motor 4, and the servo motor 4 will rotate the cam 401, so that the cam 401... One end of the push rod 403 intermittently compresses the spring 402, causing the spring 402 to undergo elastic deformation, which in turn drives the fixed rod 404 and the push rod 405 to move downward. Then, through the elastically deformed spring 402, the push rod 403, the fixed rod 404 and the push rod 405 are driven upward. The servo motor 4 continuously causes the cam 401 to perform circumferential motion, which continuously causes the push rod 405 to move up and down reciprocally inside the discharge port 5, thereby loosening the material inside the discharge port 5 and reducing the possibility of blockage.

[0038] In addition, a control panel is provided on one side of the mixing box 2. The control panel can control the start and stop of the dual-axis motor 203, the servo motor 4 and the electric telescopic rod 6. The power of the device is provided by an external power source.
