Description

Technical Field

[0001] The utility model belongs to the technical field of plastic pelletizing, and in particular relates to an anti-sticking hot cutting device. Background Art

[0002] Plastic granulation is the production process of making granular plastics by metering, mixing, hot melting and pelletizing polymer resins and various additives and auxiliaries. During plastic granulation, hot cutting equipment is required to cut the plastics (hot cutting refers to the method of pelletizing the material in a molten or semi-molten state after it is extruded from the die hole of the die head).

[0003] Under the prior art, after the plastic particles are extruded from the die hole of the die head, the die hole cannot be cleaned, and molten or semi-molten plastic will stick to the die hole. These molten or semi-molten plastics will cause the die hole size to become smaller after cooling, thereby making the extruded plastic particles of non-standard size and reducing the quality of granulation. At the same time, when the surface of the fixedly installed cutter sticks to the molten or semi-molten plastic, it is inconvenient to grind and replace the cutter. Therefore, a technical measure is proposed to solve the problem that the die hole cannot be cleaned under the prior art, and molten or semi-molten plastic will stick to the die hole, which will cause the die hole size to become smaller, thereby making the extruded plastic particles of non-standard size and reducing the quality of granulation. At the same time, when the surface of the fixedly installed cutter sticks to the molten or semi-molten plastic, it is inconvenient to grind and replace the cutter. Utility Model Content

A discharge pipe 10 is provided at the lower end of the hot melt device 9 close to the first workbench 1, and a valve 11 is provided on the discharge pipe 10. When the plastic is actually granulated, the polymer resin and various additives and auxiliary agents are stirred evenly and then added into the hot melt device 9 to perform hot melting on the polymer resin and various additives and auxiliary agents. When the polymer resin and various additives and auxiliary agents reach a hot melt state, the valve 11 is opened to discharge the hot melt plastic into the extrusion tube 7 through the discharge pipe 10. When the extrusion tube 7 is filled with hot melt plastic, the valve 11 is closed, and at this time, the plug 14 is taken out from the plug hole 12 to release the blocking of the mold hole 13 by the sealing plate 5.

A plurality of electric telescopic rods 202 are connected to the surface of the mounting plate 201. The plurality of electric telescopic rods 202 slide through the extrusion tube 7. The plurality of electric telescopic rods 202 are connected to a clamping plate 203. The clamping plate 203 is away from the plurality of electric telescopic rods 202 and is equipped with a plurality of groups of evenly distributed cleaning rods 204. The clamping plate 203 is equipped with a plurality of groups of springs 206. The clamping plate 203 is engaged with an extrusion plate 205.

The multi-section electric telescopic rod 202 is started to drive the card plate 203 to move toward the die hole 13. The movement of the card plate 203 drives the extrusion plate 205 to move. When the extrusion plate 205 moves, the hot-melt plastic is pushed out of the die hole 13. When the extrusion plate 205 contacts the extrusion tube 7, the spring 206 begins to be compressed. Under the action of the multi-section electric telescopic rod 202, the cleaning rod 204 extends from the circular hole 207 into the die hole 13 to clean the sticky hot-melt plastic inside the die hole 13.

[0028] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, the pelletizing assembly 3 includes a box body 301, which is mounted on the upper surface of the first workbench 1, and the box body 301 is connected to the side of the extrusion tube 7. A motor 306 is installed in the box body 301, and the motor 306 is connected to a connecting rod 307. The box body 301 is provided with a rotating hole 302 that is rotatably adapted to the connecting rod 307. The connecting rod 307 is connected to a connecting plate 308, and a groove 309 is provided in the connecting plate 308. The groove 309 is appropriately equipped with a block 311. A circular plate 304 is connected to the surface of the block 311, and two groups of symmetrically distributed blades 303 are installed outside the circular plate 304. A grip rod 305 is installed on the side of the circular plate 304 away from the block 311. Threaded holes 310 are provided on the connecting plate 308 and the block 311, and the threaded holes 310 are threadedly adapted to be equipped with bolts 311. 12. When starting the multi-section electric telescopic rod 202, the pelletizing assembly 3 is started synchronously, and the starting motor 306 drives the connecting rod 307 to rotate. The connecting rod 307 rotates to drive the connecting plate 308 to rotate. The connecting plate 308 rotates to drive the block 311 to rotate. The block 311 rotates to drive the circular plate 304 to rotate. The circular plate 304 rotates to drive the blade 303 to rotate to cut the hot-melt plastic. The cut hot-melt plastic falls into the cooling box 4 for cooling (there is warm water in the cooling box 4). When it is necessary to grind the hot-melt plastic stuck on the blade 303 or replace the blade 303, hold the grip 305 and use a tool to release the bolt 312 from fixing the circular plate 304. Then take the circular plate 304 out of the groove 309 and grind or replace the blade 303.

[0029] Working principle: When the plastic is actually granulated, the polymer resin and various additives and auxiliary agents are evenly mixed and then added to the hot melt device 9 to heat-melt the polymer resin and various additives and auxiliary agents. When the polymer resin and various additives and auxiliary agents reach a hot-melt state, the valve 11 is opened to discharge the hot-melt plastic into the extrusion tube 7 through the discharge pipe 10. When the inside of the extrusion tube 7 is full of hot-melt plastic, the valve 11 is closed, and the plug 14 is taken out from the plug hole 12 at this time to release the blocking of the die hole 13 by the sealing plate 5;

[0030] At this time, the push-injection hole cleaning component 2 is started, and the multi-section electric telescopic rod 202 is started to drive the card plate 203 to move toward the direction of the die hole 13. The movement of the card plate 203 drives the extrusion plate 205 to move. When the extrusion plate 205 moves, the hot melt plastic is pushed out of the die hole 13. When the extrusion plate 205 contacts the extrusion tube 7, the spring 206 begins to be compressed (when the extrusion plate 205 does not contact the extrusion tube 7, the spring 206 undergoes a small deformation, which will not cause the cleaning rod 204 to extend from the circular hole 207. The spring 206 will be deformed only when it is subjected to a large force). Under the action of the multi-section electric telescopic rod 202, the cleaning rod 204 extends from the circular hole 207 into the die hole 13 to clean the hot melt plastic sticking inside the die hole 13;

[0031] When the multi-section electric telescopic rod 202 is started, the pelletizing assembly 3 is started synchronously, and the starting motor 306 drives the connecting rod 307 to rotate, and the connecting rod 307 rotates to drive the connecting plate 308 to rotate, and the connecting plate 308 rotates to drive the clamping block 311 to rotate, and the clamping block 311 rotates to drive the circular plate 304 to rotate, and the circular plate 304 rotates to drive the blade 303 to rotate to cut the hot-melt plastic, and the cut hot-melt plastic falls into the cooling box 4 for cooling (there is warm water in the cooling box 4), and when it is necessary to grind the hot-melt plastic stuck on the blade 303 or replace the blade 303, hold the grip rod 305 and use a tool to release the bolt 312 from fixing the circular plate 304, then take the circular plate 304 out of the groove 309, and grind or replace the blade 303.
