[0002] Masterbatch is a resin component or base material in which fibers or other reinforcing materials are dispersed in reinforced plastics. In the process of making plastics, the masterbatch is generally introduced into an extruder, hot-melt mixed, and then extruded through a die.

[0003] Chinese patent authorization announcement number CN215151693U discloses a twin-screw extruder for preparing degradable masterbatch, including a box, a feed port is provided at the top of the box, a motor A is installed on one side of the outer wall of the box, a motor B is installed on one side of the outer wall of the box, and a barrel is embedded in the box to drive the rotating shaft A to rotate, and the rotation of the rotating shaft A drives the paddles to rotate, and the rotation of the paddles quantitatively feeds the crushed and degraded masterbatch into the lower end of the barrel to prevent blockage caused by excessive masterbatch delivery. The above-mentioned prior art solution has the following shortcomings: in the device, the masterbatch is introduced into the box through the feed port after being crushed by the crushing drum. Since the masterbatch cannot be directly introduced into the box during the breakage process, it will be temporarily stored in the crushing drum for a period of time. The masterbatch may surge or splash due to mechanical vibration and other conditions during the rolling process of the broken masterbatch, thereby causing waste of the masterbatch, so there is room for improvement. Utility Model Content

[0004] The utility model aims to provide a biodegradable masterbatch extrusion molding device which can prevent feed from spilling, so as to solve the problem that the existing biodegradable masterbatch extrusion molding device proposed in the above background technology is not easy to prevent the masterbatch from splashing.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a degradable masterbatch extrusion molding device that prevents feed from spilling, comprising an extrusion molding machine, a feed hopper is installed at the top of the extrusion molding machine, and a feed cover is sleeved on the outside of the top of the feed hopper, crushing rollers are arranged on both sides of the bottom end of the feed hopper, an outer ring is sleeved on the outside of the feed hopper, and temporary storage cavities are evenly opened inside the outer ring, through holes are evenly opened on the outside of the feed hopper, and the positions of the through holes correspond one to one with the positions of the temporary storage cavities, a support ring is installed at the top of the inside of the feed hopper, and a rotating block passes through the inside of the support ring, a guide groove is opened on the outside of the rotating block, and balls are evenly installed inside the guide groove, one side of the ball is embedded in the inner wall of the support ring, a bulking mechanism is arranged on the top of the rotating block, and a discharge pipe is installed on one side of the extrusion molding machine.

[0006] When using a biodegradable masterbatch extrusion molding device that prevents feed spillage of the present technical solution, the outer ring acts so that when the masterbatch surges upward, the masterbatch can be temporarily stored inside the temporary storage cavity, and the difference between the inner diameter of the temporary storage cavity and the inner diameter of the feed hopper is utilized to reduce the possible continuous surge of the masterbatch during the crushing process.

[0007] Preferably, the material dispersing mechanism comprises a material guide block installed on the top of the rotating block, and material guide blades are evenly installed on the outer side of the bottom end of the material guide block, and material guide grooves are evenly opened on the top of the material guide block.

[0008] Preferably, the material guide trough is scattered on the material guide block, the bottom end of the material guide trough corresponds to one side position of the material guide blade, and the material guide blade is arranged on the material guide block in an inclined shape.

[0009] Preferably, the temporary storage cavities are distributed in annular shapes at equal intervals inside the outer ring, and the cross-section of the temporary storage cavities is rectangular.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the degradable masterbatch extrusion molding device for preventing feed spillage not only improves the anti-splashing effect of the masterbatch during the feeding process, but also facilitates the adjustment of the extruded material diameter;

[0014] (1) Through the action of the outer ring, when the masterbatch surges upward, the masterbatch can be temporarily stored inside the temporary storage chamber. The difference between the inner diameter of the temporary storage chamber and the inner diameter of the feed hopper is used to reduce the possible continuous surge of the masterbatch during the crushing process. The rotating block and the support ring are used to block the top of the feed hopper to a certain extent, thereby reducing the opening size of the feed hopper, thereby reducing the upward splashing of the masterbatch during the crushing process, and further improving the anti-splashing effect of the masterbatch during the feeding process;

[0015] The guide blades and guide troughs are used to guide the falling of the masterbatch, so that the masterbatch falls into the feed hopper in a splashing shape, reducing the accumulation of the masterbatch in the same position, so as to promote the rapid crushing effect of the masterbatch;

[0016] (2) By using the adjusting tube, the diameter of the material when it is extruded is reduced compared to the discharge tube, and the screwing effect of the thread is utilized to facilitate the disassembly of the adjusting tube, so that the material can be directly extruded from the discharge tube, thereby achieving the effect of changing the extrusion diameter of the material.

[0025] See also Figure 1-5The utility model provides an embodiment: a degradable masterbatch extrusion molding device for preventing feed spillage, comprising an extrusion molding machine 1, a feed hopper 2 is installed at the top of the extrusion molding machine 1, and a feed cover 6 is sleeved on the outside of the top of the feed hopper 2, crushing rollers 20 are arranged on both sides of the bottom of the feed hopper 2, an outer ring 3 is sleeved on the outside of the feed hopper 2, and temporary storage cavities 4 are evenly opened inside the outer ring 3;

[0026] The temporary storage chambers 4 are distributed in an equidistant ring shape inside the outer ring 3, and the cross section of the temporary storage chambers 4 is rectangular;

[0027] A guide plate 18 is installed inside the temporary storage chamber 4, and the top of the guide plate 18 is inclined, and the height of the guide plate 18 is lower on the side close to the through hole 5;

[0028] Specifically, Figure 1 , Figure 4 As shown, the outer ring 3 is used to temporarily store the upwelling masterbatch during use, and since the inner diameter of the outer ring 3 is larger than the inner diameter of the feed hopper 2, the masterbatch is prevented from overflowing, and at the same time, under the action of the guide plate 18, the masterbatch can automatically and gradually fall to the bottom of the feed hopper 2 for crushing;

[0029] The outer side of the feed hopper 2 is evenly provided with through holes 5, and the positions of the through holes 5 correspond to the positions of the temporary storage chambers 4 one by one. A support ring 7 is installed at the top of the inside of the feed hopper 2, and a rotating block 8 is penetrated inside the support ring 7. A guide groove 14 is opened outside the rotating block 8, and balls 13 are evenly installed inside the guide groove 14. One side of the ball 13 is embedded in the inner wall of the support ring 7. A bulking mechanism is provided at the top of the rotating block 8.

[0030] The material dispersing mechanism includes a material guide block 15 installed on the top of the rotating block 8, and material guide blades 17 are evenly installed on the outer side of the bottom of the material guide block 15, and material guide grooves 16 are evenly opened on the top of the material guide block 15;

[0031] The guide groove 16 is scattered on the guide block 15, and the bottom end of the guide groove 16 corresponds to one side of the guide blade 17, and the guide blade 17 is arranged on the guide block 15 in an inclined shape;

[0032] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, when in use, under the action of the guide block 15 and the guide trough 16, the masterbatch is scattered and dropped to prevent the masterbatch from accumulating at a single position inside the feed hopper 2 and reducing the overflow of the masterbatch. At the same time, the top opening of the feed hopper 2 is shielded to a certain extent by the rotating block 8 to reduce the masterbatch from splashing out during the crushing process.

[0033] A discharge pipe 9 is installed on one side of the extrusion molding machine 1;

[0034] The outer part of the discharge pipe 9 is provided with a connecting sleeve 10, and a locking sleeve 11 is installed inside the connecting sleeve 10, one end of the locking sleeve 11 extends to the inside of the discharge pipe 9, and an adjusting tube 12 is installed inside the locking sleeve 11. A sealing ring 19 is sleeved on the outer side of the locking sleeve 11 close to the discharge pipe 9, and the outer side of the sealing ring 19 abuts against the inner wall of the discharge pipe 9;

[0035] The discharge pipe 9 is threadedly connected to the connecting sleeve 10, the inner diameter cross section of the adjusting pipe 12 is trumpet-shaped, and the inner diameter of the adjusting pipe 12 gradually decreases from left to right;

[0036] Specifically, Figure 1 , Figure 5 As shown, when in use, the guiding effect of the adjusting tube 12 is used to further squeeze the extrudate inside the discharge tube 9, thereby changing the diameter of the extrudate. At the same time, under the action of the sealing ring 19, the tightness between the locking sleeve 11 and the discharge tube 9 is improved to prevent the extrudate from overflowing from the gap.

[0037] Working principle: When the utility model is used, the masterbatch is first poured into the feed hopper 2 through the feed cover 6. During the falling process of the masterbatch, it will contact the guide block 15 and scatter along the guide groove 16 to the guide blade 17 to increase the dispersion of the masterbatch inside the feed hopper 2. When the impact force of the masterbatch falling is large, the guide blade 17 is inclined, which can drive the guide block 15 to rotate, so that the ball 13 rolls along the guide groove 14, so as to further change the falling position of the masterbatch, so as to reduce the accumulation of the masterbatch at a single position;

[0038] Secondly, the crushing roller 20 is started synchronously. When the masterbatch falls onto the crushing roller 20, it is crushed by the crushing roller 20, so that the masterbatch enters the interior of the extruder 1. The extruder 1 is started to heat-melt and extrude the masterbatch, so that the material moves toward the discharge pipe 9 and is extruded into a columnar strip through the discharge pipe 9.

[0039] Finally, when the diameter of the extrudate needs to be changed, the connecting sleeve 10 can be installed on the outside of the discharge pipe 9 by screwing, and the locking sleeve 11 can be inserted into the inside of the discharge pipe 9. The sealing ring 19 is used to increase the contact tightness between the locking sleeve 11 and the discharge pipe 9, so that the extrudate is gradually compressed inward under the action of the adjusting tube 12 to reduce the diameter of the extrudate and achieve the adjustment effect.
