Description

Technical Field

[0002] As an important part of the new chemical material field, modified plastics have also been listed as one of the key scientific and technological fields for development by the country. Since 2007, China has successively introduced various policies to promote the development of the modified plastic industry. The automotive and home appliance industries are hotspots for the development of modified plastics, with a combined share of over 50%.

[0003] For example, a cutting device for modified plastic processing and extrusion disclosed in the utility model with the application number 202021880130.6 has a pair of clamping mechanisms on the operating table. Through the mounting frame, lower pressing plate, a pair of horizontal pressing plates, upper pressing plate and top plate, the plastic can be clamped, so that the utility model has the advantage of good clamping effect.

[0004] The current situation similar to the above application still has deficiencies:

[0005] This kind of cutting device for modified plastic processing and extrusion uses the upper and lower pressing plates, horizontal pressing plates and the elastic force of springs to push the pressing plates to clamp the plastic. Although it has a certain clamping effect, under the action of external forces or external tensile forces, etc., the plastic will squeeze the pressing plate to one side, resulting in the plastic not being centered. The non-centered plastic will bring many disadvantages to the cutting work. For example, the cutting size deviation caused by the plastic offset, the large product size deviation, reducing the product quality, and the non-centered plastic is unevenly stressed during the cutting process, resulting in vibration and shaking due to uneven stress, reducing the cutting stability and leading to poor cutting.

[0006] Therefore, a cutting device for modified plastic processing and extrusion is designed to optimize the above problems. Content of the Utility Model

[0025] To make the technical solutions of the present utility model clearer and more definite for those skilled in the art, the present utility model will be further described in detail below in conjunction with the embodiments and the drawings, but the embodiments of the present utility model are not limited thereto.

[0026] Such as Figures 1 - 4As shown in the figure, this embodiment provides a cutting device for processing and extruding modified plastics, including a housing 1. A hydraulic rod 2 is installed on the top of the housing 1. A tool rest 3 is fixed to the telescopic end of the hydraulic rod 2. A cutting knife 4 is installed inside the tool rest 3. A limiting tube 5 is installed through one side of the housing 1. Protective rings are fixed inside both ends of the limiting tube 5, and protective strips are evenly arranged inside the protective rings. The arrangement of the protective strips reduces the entry of dust and impurities and affects the use of the clamping components. An internally threaded tube 6 is threadedly connected to the outside of the limiting tube 5. A protective layer is sleeved on the outside of the internally threaded tube 6, and anti-slip patterns are arranged on the outside of the protective layer. The protective layer and the anti-slip patterns facilitate the staff to rotate the internally threaded tube 6, and the operation is more labor-saving and convenient. A tapered tube 7 is fixed to one side of the internally threaded tube 6. T-shaped rods 8 are evenly installed through the outside of the limiting tube 5, and the T-shaped rods 8 are all slidably connected to the limiting tube 5. Semi-circular blocks 10 are fixed to the ends of the T-shaped rods 8 away from each other, and the semi-circular blocks 10 are all slidably connected to the inside of the tapered tube 7. Springs 9 are sleeved on the outside of the T-shaped rods 8, and the springs 9 are all fixed to the outside of the limiting tube 5. Limiting wheels 11 are installed at the other ends of the T-shaped rods 8.

[0027] Specifically, the modified plastic is fed into the limiting tube 5 and delivered outwards. The internally threaded tube 6 is screwed to the left. The internally threaded tube 6 drives the tapered tube 7 to move to the left. Under the push of the tapered tube 7, the semi-circular blocks 10 and the T-shaped rods 8 move towards the center position inside the limiting tube 5 until the limiting wheels 11 at the ends of the T-shaped rods 8 abut against the outside of the modified plastic to limit it. Then, it is cut by the cutting knife 4.

[0028] As Figure 1 and Figure 3 shown in the figure, guide blocks 21 are symmetrically arranged on the inner bottom wall of the housing 1. The guide blocks 21 are all triangular blocks, and wear-resistant layers are arranged on the outside of the guide blocks 21. The triangular guide blocks 21 make it easier for impurities and debris to fall under the action of gravity. A pull rod 17 is installed through one side of the housing 1, and the pull rod 17 is slidably connected to the housing 1. One end of the pull rod 17 penetrates and extends to the outside of the housing 1, and a rotating handle is fixed to one end of the pull rod 17. The rotating handle facilitates the staff to push and pull the pull rod 17, and the operation is convenient. A fixing rod 18 is fixed to one end of the pull rod 17. Scrapers 19 are fixed to both ends of the fixing rod 18, and the scrapers 19 are slidably connected to the guide blocks 21. A push plate 20 is fixed to the bottom of the fixing rod 18. A sliding frame 16 is slidably connected to the bottom of the housing 1. A fixing port 15 is opened at the connection between the housing 1 and the sliding frame 16.

[0029] Specifically, the cut modified plastic segments are ejected by the newly extruded modified plastic and fall into the outer collection box, while the debris and impurities generated by the cutting first fall on the diversion block 21 and are collected inside the sliding frame 16 through the diversion block 21. Push and pull the pull rod 17 back and forth, and the pull rod 17 drives the fixed rod 18, the scraper 19 and the push plate 20 to move simultaneously. The scraper 19 sweeps the debris on the diversion block 21 into the sliding frame 16 respectively, and the push plate 20 pushes the debris and impurities accumulated in the sliding frame 16 outwards.

[0030] As Figure 1 shown, a baffle 12 is fixed to the side of the housing 1 away from the limiting tube 5. A through hole 13 is formed in the baffle 12, and a plurality of blocking bars 14 are uniformly arranged inside the through hole 13.

[0031] Specifically, the through hole 13 is used for the passage of the modified plastic, and the blocking bars 14 block the splashing debris or dust, reducing the splashing of the debris and dust.
