Description

Technical Field

[0001] This utility model relates to the technical field of masterbatch screening machines, specifically a masterbatch screening device. Background Technology

[0002] Color masterbatch is a type of polymer composite material granule produced by uniformly mixing a high proportion of pigments, additives, and carrier resin using extrusion granulation technology. In the granulation stage, the material is plasticized by an extruder to form a strip-shaped melt, which is then cooled and solidified in a water bath before being cut into uniform granules by a pelletizer. However, in actual production, long, strip-shaped defective products that are not completely cut often occur, requiring a screening device to separate these defective products.

[0003] However, screening devices are usually located directly below the cutter or hopper. Some long strips of defective products falling vertically may pass directly through the screen holes. In addition, if the feeding speed is too fast, a large amount of masterbatch raw materials will accumulate together, causing long strips of defective products to fall through the screen holes in a vertical state. All of these will reduce screening efficiency and require secondary screening, thus affecting work efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a masterbatch screening device, which solves the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

A flat push inclined surface is provided on the lower side of the flat push scraper. A flat push gap is provided between the flat push inclined surface and the inclined guide plate.

[0009] Preferably, the two ends of the mounting beam are overlapped and set on the upper edge of the screening machine body, and the end of the mounting beam is bent downward with a connecting plate.

[0013] (III) Beneficial Effects

[0014] This invention provides a color masterbatch screening device. It has the following beneficial effects:

[0015] 1. In this utility model, the inclined guide plate is used to feed the color masterbatch raw material. The vertically falling long strip-shaped defective products will not directly contact the screen. Under the action of vibration, they slide down from the inclined part of the inclined guide plate. After the color masterbatch passes through the combing ribs, the color masterbatch raw material will be spread out evenly, reducing the accumulation thickness of the color masterbatch and preventing the color masterbatch from accumulating and squeezing the long strip-shaped defective products vertically. The flat pusher scraper can be used to push and knock down the long strip-shaped defective products in the vertical state, which can effectively prevent the long strip-shaped defective products in the vertical state from contacting the screen.

[0016] 2. In this utility model, the height of the flat-push scraper can be adjusted by the lifting screw to change the height of the flat-push gap, which can control the speed at which the color masterbatch raw material passes through the separation gap, thereby changing the feeding speed and thus changing the range of flat-spreading and dispersion, and improving the screening effect.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a color masterbatch screening device, such as Figures 1-5 As shown, the system includes a screening machine body 1, a screen 2 with several screen holes installed inside the screening machine body 1, a screening cavity formed between the screening machine body 1 and the screening cavity, and a material guiding mechanism fixedly installed inside the screening cavity.

[0025] The material guiding mechanism includes a mounting beam 4 fixed to the screening machine body 1, an inclined guide plate 3 abutting against the upper side of the screen 2, several combing ribs 5 connecting the mounting beam 4 and the inclined guide plate 3, and a flat push scraper 6 slidably mounted on the mounting beam 4. The two ends of the mounting beam 4 overlap and are set on the upper edge of the screening machine body 1. The end of the mounting beam 4 is bent downward with a connecting plate 7. The connecting plate 7 is threaded with a positioning bolt 8. The end of the positioning bolt 8 abuts against the outer wall of the screening machine body 1. The inclined guide plate 3 includes, from front to back, a feeding part, an inclined part, and a fitting part. The feeding section can be used directly below the cutter or hopper to receive color masterbatch raw materials. The vertically falling color masterbatch raw materials fall directly onto the feeding section, preventing long strips of defective products from directly contacting the screen 2 and falling directly from the screen holes to the lower layer. The feeding section is horizontally against the inner wall of the screening machine body 1. The inclined section extends downward from the feeding section, and the bonding section extends horizontally from the inclined section. The bonding section is horizontally against the upper side of the screen 2 and remains flush, so that the color masterbatch raw materials passing through the inclined guide plate 3 can smoothly slide down the feeding section onto the screen 2.

[0026] The lower end of the combing rib 5 is fixedly connected to the upper side of the inclined part. The front side of the combing rib 5 is set as a cone. The color masterbatch raw material slides from the inclined part to the front side of the combing rib 5. A separation gap is provided between two adjacent combing ribs 5. The cone structure can prevent long strip-shaped defective products from getting stuck on the front side of the combing rib 5 and causing blockage of the separation gap.

[0027] The flat-push scraper 6 is vertically slidably installed in the partition gap. A guide beam 9 is connected to the rear side of several flat-push scrapers 6. A guide groove is provided on the rear side of the combing rib 5. Guide blocks 10 corresponding to the positions of the guide grooves are spaced apart on the guide beam 9. The guide blocks 10 are slidably installed in the guide grooves.

[0028] The lower side of the flat-push scraper 6 is provided with a flat-push inclined surface, and a flat-push gap is provided between the flat-push inclined surface and the inclined guide plate 3. Under the action of vibration, the color masterbatch raw material slides down along the inclined part of the inclined guide plate 3 and passes through the flat-push gap. By controlling the height of the flat-push gap, the flow speed of the color masterbatch raw material passing through the gap can be changed. Changing the flow speed can change the spreading effect of the color masterbatch raw material without changing the feeding speed of the cutting machine or hopper. At the same time, the flat-push inclined surface can block the vertically protruding long strip-shaped defective products when the color masterbatch accumulates, push the strip-shaped defective products down, and keep the long strip-shaped defective products lying flat after passing through the flat-push gap. They will not directly touch the screen 2 vertically, and prevent the long strip-shaped defective products from falling out of the screen holes. The upper side of the flat-push scraper 6 extends upward with a sliding baffle 12. The sliding baffle 12 is slidably set in the gap, which can prevent the color masterbatch raw material from jumping over the upper side of the flat-push scraper 6 and accumulating in the flat-push scraper 6, which is inconvenient to clean.

[0029] A vertical optical axis 13 is fixed to the upper side of the sliding baffle 12. A guide hole is provided on the mounting beam 4 corresponding to the position of the vertical optical axis 13. The vertical optical axis 13 slides through the guide hole and extends upward. A horizontal beam frame 14 is connected to the top of the vertical optical axis 13. A threaded hole is provided in the middle of the horizontal beam frame 14. A flange seat is fixed on the mounting beam 4. A lifting screw 11 is rotatably connected to the flange seat. The lifting screw 11 is threaded through the threaded hole. A knob handle is provided on the top of the lifting screw 11.

[0030] Working principle:

[0031] In this invention, the material guiding mechanism is placed inside the screening machine body 1, the mounting beam 4 is placed and overlapped on the upper edge of the screening machine body 1, the material feeding part abuts against the inner wall of the screening machine body 1, and the fitting part abuts against the upper side of the screen 2. The positioning bolt 8 is screwed on so that the positioning bolt 8 abuts against the outer wall of the screening machine body 1 to form a contact lock, which can fix the material guiding mechanism on the screening machine body 1. This allows the color masterbatch raw material that falls vertically from the self-cutting machine or hopper to fall directly onto the inclined guide plate 3. The vertically falling color masterbatch raw material and long strip-shaped defective products will not directly contact the screen 2, thus preventing long strip-shaped defective products in a vertical state from passing directly through the screen holes.

[0032] The masterbatch material piled up on the inclined guide plate 3 is conveyed forward under vibration. It slides down through the inclined part of the inclined guide plate 3. During the sliding process, the masterbatch material piled up together is gradually dispersed and dispersed by the combing ribs 5, so that the masterbatch material piled up together is spread out flat. The height of the flat push scraper 6 can be adjusted to change the speed at which the masterbatch material passes through the dividing gap, so as to match the feeding speed of the cutter or hopper and the spreading range to achieve a suitable ratio and keep the masterbatch material properly dispersed. This allows the long strip-shaped defective products to lie flat on their own. At the same time, the flat push slope of the flat push scraper 6 can push the strip-shaped defective products down, so that the long strip-shaped defective products passing through the flat push gap are kept in a flat state, avoiding the vertical strip-shaped defective products from entering the lower layer through the screen 2 through the screen holes, which would reduce the screening efficiency.
