Description

Technical Field

[0001] The utility model relates to the technical field of feeding equipment, in particular to a feeding platform for a granulator. Background Art

[0002] Polyvinylidene fluoride, abbreviated as PVDF, is a highly non-reactive thermoplastic fluoropolymer that is soluble in strong polar solvents such as dimethylacetamide. It has excellent properties such as anti-aging, chemical resistance, weather resistance, and resistance to ultraviolet radiation. It can be used as an engineering plastic for making sealing rings, corrosion-resistant equipment, and capacitors. It is also used as a coating, insulating material, and ion exchange membrane material. In the PVDF production and granulation process, the raw materials are usually first melted through an extruder and then extruded. The cooled extruded tubular or strip raw materials are then cut and granulated.

[0003] When the granulator is in use, it uses a feeding device to feed the material. However, the screen in the feeding port is stationary. When feeding, PVDF accumulates on the surface of the screen, and the raw materials are not easy to fall, which affects the feeding efficiency. At the same time, some feeding devices cannot control the feeding speed. The staff judges based on their own experience, resulting in uneven feeding speed, which reduces the practicality of the device. Utility Model Content

[0022] In order to enable people skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0023] The core of this application is to provide a feeding platform for a granulator, which solves the problem that the screen in the feeding port of the existing feeding device is stationary, PVDF accumulates on the surface of the screen during feeding, and the raw materials are not easy to fall, affecting the feeding efficiency. At the same time, some feeding devices cannot control the feeding speed, and the staff makes judgments based on their own experience, resulting in uneven feeding speed, which reduces the practicality of the device.

[0024] Figure 1 This is a schematic structural diagram of a feeding platform for a granulator provided by the utility model. Figure 2 This is a schematic diagram of the structure of a screening component provided by the utility model. Figure 3 A top view of a screen provided by the utility model, Figure 4 This is a side cross-sectional diagram of a discharge box provided by the utility model, see Figures 1 to 4 shown.

[0025] A feeding platform for a granulator includes a feeding box 1, the top of which is connected to a feeding hopper 2. PVDF granulation raw materials are added to the feeding box 1 through the feeding hopper 2. Preferably, a blocking cover 201 is provided on the top of the feeding hopper 2, and a handle 202 is provided on the upper surface wall of the blocking cover 201. When not in use, the blocking cover 201 can be used to cover the feeding hopper 2 using the handle 202 to prevent dust from falling into the feeding box 1 and reduce the workload of the staff for cleaning. A screen 3 is arranged obliquely in the feed box 1, and the adhered block and large particle raw materials that do not meet the use requirements are screened out through the screen 3. Screening components 4 are provided on both sides of the upper end of the screen 3. The screening component 4 is arranged on the inner side wall of the feed box 1. The feed box 1 is provided with a coarse material outlet 301 at the lower end of the screen 3. In actual use, the screening component 4 is used to drive the screen 3 to shake, so that the PVDF accumulated on the screen 3 is dispersed and accumulated by shaking. The PVDF particles that meet the granulation requirements can fall quickly from the sieve holes, making the filtration more sufficient, preventing the screen 3 from being blocked, and improving the filtration efficiency. The large particles screened out are discharged from the feed box 1 through the coarse material outlet 301.

[0026] The PVDF particles that meet the use requirements and are screened out by the screen 3 fall to the bottom of the feeding box 1. The bottom of the feeding box 1 is conical, and a discharge box 7 is fixed to the bottom of the feeding box 1. The discharge box 7 is hollow and has a discharge port 8. A material control component is provided in the discharge port 8. A screw conveyor 12 is connected to the bottom of the discharge box 7. The end of the screw conveyor 12 away from the material control component is connected to the feed port of the granulator 14 through a feeding pipe 13. The material control component is used to evenly convey the PVDF raw material to the screw conveyor 12. The structure and working principle of the screw conveyor 12 can be referred to the prior art. The screw conveyor 12 conveys the material, and the material enters the granulator 14 through the feeding pipe 13, thereby controlling the feeding speed.

[0027] In order to prevent the discharge port 8 from being blocked, preferably, the material control assembly includes several groups of limit plates 9 and a rotating shaft 10. The limit plates 9 are connected to the rotating shaft 10. One end of the rotating shaft 10 is connected to a drive motor 11. The drive motor 11 arranged outside drives the rotating shaft 10 to rotate, thereby allowing the limit plates 9 to drive the raw materials into the screw conveyor 12. Preferably, six groups of limit plates 9 are provided. The limit plates 9 are circumferentially distributed on the outer peripheral surface of the rotating shaft 10. Since the limit plates 9 are circumferentially distributed on the outer peripheral surface of the rotating shaft 10 and are arranged at equal intervals, the rotation of the rotating shaft 10 can make the raw materials inside the feeding box 1 uniformly discharged, and can also control the speed of feeding into the granulator 14 to prevent the discharge port 8 from being blocked.

[0028] In this embodiment, preferably, the screening component 4 includes a sliding rod 401 and a vibration motor 402. The sliding rod 401 is vertically arranged and both ends are mounted on the inner wall of the feeding box 1 through a fixing plate 403. The outer wall of the sliding rod 401 is sleeved with a sliding block 404. The sliding block 404 can move up and down on the sliding rod 401. The other end of the sliding block 404 is provided with a connecting block 405. The vibration motor 402 is fixed on the top of the connecting block 405. The other end of the connecting block 405 is connected to the screen 3. The connecting block 405 slides The block 404 and the screen 3 are connected together, and the outer wall of the sliding rod 401 is provided with a spring 406, which is symmetrically distributed on both sides of the sliding block 404 and abuts against the upper and lower fixed plates 403. In actual use, the vibration motor 402 is started, and the vibration motor 402 drives the connecting block 405 to shake up and down, and the sliding block 404 connected to the connecting block 405 slides up and down on the sliding rod 401, thereby causing the screen 3 to shake up and down. The screening component 4 is used to make the shaking amplitude of the screen 3 larger, thereby further improving the filtration efficiency.

[0029] Preferably, the angle between the screen 3 and the horizontal plane is 30°. The inclined screen 3 can quickly screen out large particles of raw materials that do not meet the use requirements and discharge them from the feeding box 1.

[0030] Preferably, buffer plates 5 are symmetrically arranged in the feeding box 1, and the longitudinal sections of the buffer plates 5 are all arranged in an inclined structure. When in use, the inclined buffer plates 5 can effectively slow down the material discharge speed, thereby effectively preventing the lower end of the feeding box 1 from being blocked.

[0031] Furthermore, buffer blocks 6 are evenly distributed on the upper surface of the buffer plate 5, and the longitudinal section of the buffer blocks 6 is set to an arc structure. The evenly distributed buffer blocks 6 can further slow down the material discharge speed. Since the buffer blocks 6 are set to an arc structure, the material is prevented from being retained on the upper surface of the buffer plate 5.

[0032] The present application provides a feeding platform for a granulator, the working principle of which is as follows: PVDF granulation raw materials are added to the feeding box 1 through the feeding hopper 2, the vibration motor 402 is started, the vibration motor 402 drives the connecting block 405 to shake up and down, and the sliding block 404 connected to the connecting block 405 slides up and down on the sliding rod 401, thereby causing the screen 3 to shake up and down, and the PVDF accumulated on the screen 3 is dispersed and accumulated by shaking, and the PVDF particles that meet the granulation requirements can quickly fall from the sieve holes, and the large particles screened out are away from the feeding box 1 through the coarse material outlet 301. The PVDF particles that meet the use requirements that are screened out by the screen 3 fall to the bottom of the feeding box 1, and the drive motor 11 set on the outside drives the rotating shaft 10 to rotate, thereby causing the limit plate 9 to drive the raw materials into the screw conveyor 12, and the screw conveyor 12 transports the materials, and the materials enter the granulator 14 through the feeding pipe 13, thereby controlling the feeding speed.

[0033] Other embodiments of the present invention will readily occur to those skilled in the art after considering the specification and practicing the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of this application and incorporate common knowledge or customary techniques in the art disclosed herein.
