Description

Technical Field

[0001] The present invention relates to the technical field of plastic recycling, and more particularly to a granulator for plastic processing. Background Art

[0002] The main machine of the plastic granulator is an extruder, which consists of an extrusion system, a transmission system and a heating and cooling system. It vigorously develops renewable resources and turns waste into treasure. The plastic granulator is mainly used to process waste plastic films, woven bags, beverage bottles, daily necessities, etc. Most common waste plastics can be reproduced using the plastic granulator.

[0003] According to Chinese patent No. CN212653687U, the cleaning frame, the filtering frame and the discrete frame are integrated into a whole, and the plastic particles produced by the granulator body enter the discrete frame for discrete separation, filtering, reducing the attachment of the plastic particles, and then cleaning, further reducing the attachment of the plastic particles, improving product quality, and meeting the purpose of use requirements.

[0004] However, the reason why there are many attachments on plastic particles is that the heat dissipation effect is not good, causing the plastic particles to melt and increase the viscosity of the plastic particles, making them stick to threaded rods, etc., resulting in plastic blockage. Therefore, we proposed a granulator for plastic processing. Summary of the invention

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Refer to the instruction manual Figure 1-7 A granulator for plastic processing according to an embodiment of the present invention comprises a granulator assembly 1, a filter screening frame 5 is fixedly connected to the top of the granulator assembly 1, the granulator assembly 1 and the filter screening frame 5 are arranged in a connected state, one end of the filter screening frame 5 is fixedly connected to a roller material transfer frame 3 in a connected state, and a material transfer funnel 4 is fixedly connected to the top of the roller material transfer frame 3 in a connected state;

[0030] One end of the roller material conveying frame 3 is rotatably connected with the first rotating rod 6, and the outer surface of the first rotating rod 6 is plugged with a threaded positioning block 11, and the two ends of the threaded positioning block 11 are fixedly installed on the outer surface of the roller material conveying frame 3 through two sets of positioning screws 12. The first rotating rod 6 passes through one end of the roller material conveying frame 3 and is fixedly connected with a stirring frame 24. The inner wall of the roller material conveying frame 3 is fixedly connected with a plastic threaded transmission channel 25. The threaded track opened inside the stirring frame 24 is consistent with the threaded track opened inside the plastic threaded transmission channel 25. The plastic threaded transmission channel 25 and the stirring frame 24 form a compression space. The plastic threaded transmission channel 25 is provided with a coolant flow groove 26. The same threaded track of the two can speed up the transmission operation of the heated plastic material and can fully extrude the heated plastic material.

[0031] The interior of the coolant circulation groove 26 is fixedly connected to an airbag water storage frame 30 whose outer wall is made of rubber through a cavity opened therein, and a stirring piece 35 with telescopic performance is fixedly connected to the outer surface of the airbag water storage frame 30, and two sets of limiting pulleys 32 are fixedly connected to the outer surface of the airbag water storage frame 30, and the outer surfaces of the two sets of limiting pulleys 32 are slidably connected to the connecting rod 27, and the connecting rod 27 is fixedly installed on the inner wall of the coolant circulation groove 26. As the hinge frame 31 slides, the rolling ball 34 transmits the pressure to the airbag water storage frame 30. When the airbag water storage frame 30 shakes, the airbag water storage frame 30 shakes left and right along the track of the connecting rod 27 through the two sets of limiting pulleys 32, thereby adjusting the external left and right pressures, and when the hinge frame 31 transmits the upper pressure, the rolling ball 34 drives the stirring piece 35 to telescopic motion along the surface of the airbag water storage frame 30, and at the same time, the auxiliary spring 33 is used for shock absorption, thereby improving the stability of the cooling system and avoiding damage to the water pipe.

[0032] Refer to the instruction manual Figure 7-8 The top of the airbag water storage rack 30 is fixedly connected with an auxiliary spring 33, and the top of the auxiliary spring 33 is fixedly connected with a hinge frame 31. The end of the hinge frame 31 away from the stirring frame 24 is hinged on the inner wall of the coolant circulation groove 26. As the plastic material is transferred from the material transfer funnel 4 to the inside of the roller material transfer rack 3, as the first rotating rod 6 drives the stirring frame 24 to rotate, the heated plastic material is extruded and transmitted. As the heated plastic material contacts the inner wall of the coolant circulation groove 26, the cavity inside the coolant circulation groove 26 will vibrate due to the extrusion transmission between the two, and the hinge frame 31 is deflected along the vibration direction. During the deflection process, the hinge frame 31 uses the auxiliary spring 33 to perform vibration buffering to prevent the surface of the airbag water storage rack 30 below from being damaged due to excessive vibration, thereby affecting the subsequent heat dissipation steps.

[0033] Refer to the instruction manual Figure 5-8 , the end of the hinge frame 31 away from the coolant circulation groove 26 is hinged with a ball 34, and the ball 34 is fixedly connected to one end of the stirring member 35. The end of the airbag water storage rack 30 passing through the coolant circulation groove 26 is fixedly connected with a water pump 29 for replenishing the water source inside the airbag water storage rack 30. The water pump 29 drives the water to circulate back and forth. The method can refer to water cooling, so that the airbag water storage rack 30 fits the outer wall of the molding thread conveyor 25 to maintain a constant temperature and accelerate the cooling and molding of the plastic. The number of airbag water storage racks 30 is multiple groups, and the multiple groups of airbag water storage racks 30 are fixedly arranged through connecting rods 27. The multiple groups of airbag water storage racks 30 are fixedly connected with water pipes 28 in a connected state. The connected state of water causes the multiple groups of airbag water storage racks 30 to use the water pipes 28 to synchronize the water pressure, which is convenient for the water pump to continuously replace the cooling water to form a cooling water cycle;

[0034] Furthermore, two groups of atomizing components 23 are fixedly installed on the inner wall of the filtering and screening frame 5, and a filter screen 22 is fixedly connected to the inner wall of the filtering and screening frame 5.

The atomizing component 23 sprays atomized agent on the incoming plastic particles to accelerate the production of plastic particles.

[0035] Refer to the instruction manual Figure 1-5 One end of the first rotating rod 6 is fixedly connected to the limiting ring 10, and a conveyor belt 7 is slidably connected between the first rotating rod 6 and the limiting ring 10. The end of the conveyor belt 7 away from the limiting ring 10 is slidably installed on the surface of the first separation screen 8. The bottom end of the first separation screen 8 is rotatably connected to a load-bearing frame 9, and the load-bearing frame 9 is fixedly installed at one end of the granulation component 1. The bottom end of the granulation component 1 is fixedly connected to a collecting base 2. The first rotating rod 6 is arranged to keep a synchronous rotation state with the first separation screen 8 through the conveyor belt 7. When the first rotating rod 6 rotates, the first rotating rod 6 drives the conveyor belt 7 to rotate. The first separation screen 8 rotates synchronously, so that the plastic extrusion step inside the drum material transfer rack 3 and the distribution step below can be carried out together, thereby improving the overall processing efficiency. The first separation screen 8 passes through one end of the granulation component 1 and is fixedly connected to the first gear 13. The first separation screen 8 passes through one end of the first gear 13 and is provided with multiple sets of slide rails 17. The multiple sets of slide rails 17 are arranged in a ring state about the outer surface of the first separation screen 8. The outer surface of the slide rail 17 is slidably connected with an inclined separation block 16. When the first gear 13 rotates through the first separation screen 8, the plastic particle group that is meshed with the plastic particles dropped from the filtering and screening rack 5 is stirred. The multiple sets of inclined separation blocks 16 and the slide rails 17 are respectively arranged in a ring shape on the surface of the first separation screen 8 to expand the distribution efficiency of the plastic particle group. The outer surface of the first gear 13 is meshed and connected with the second gear 14. The second separation screen 15 is fixedly connected inside the second gear 14. The second separation screen 15 is rotatably installed at one end of the granulation component 1. There are two sets of inclined separation blocks 16. One set of inclined separation blocks 16 is located on the outer surface of the first separation screen 8, and the other set of inclined separation blocks 16 is located on the outer surface of the first separation screen 8. The block 16 is located on the outer surface of the second separation screen 15, the first gear 13 drives the second gear 14 to rotate synchronously by meshing with the second gear 14, and the second gear 14 drives the second separation screen 15 to rotate, and the inclined separation block 16 and the slide rail 17 located on the surface of the second separation screen 15 and the inclined separation block 16 and the slide rail 17 located on the surface of the first separation screen 8 fully rub the fallen plastic particle group through the gap interlayer staggered in pairs, so that the plastic particle group is accelerated to separate into plastic particles under repeated friction and the clamping of the positioning gap;

[0036] Furthermore, the number of the inclined separation blocks 16 is consistent with the number of the slide rails 17, one end of the inclined separation block 16 is fixedly connected to the limit insertion tube 18, one end of the limit insertion tube 18 is fixedly connected to a spring 19, one end of the spring 19 is fixedly connected to a support block 20, the support block 20 is located at one end of the spring 19 and is fixedly connected to a limit slide 21, the limit slide 21 is set to the limit insertion tube 18 in a limit state, when the two inclined separation blocks 16 are in contact, when the outer surface of the inclined separation block 16 is squeezed by the plastic particle group, the inclined separation block 16 moves along It slides in the groove of the slide rail 17, and can move outward or inward according to the direction of force. The inclined separation block 16 drives the limiting insert 18 to move under the clamping of the limiting slide 21. The spring 19 buffers the external pressure, thereby positioning the inclined separation block 16. As the plastic particle clusters are rubbed and separated, the plastic particle clusters adhere to the inclined separation block 16. As the inclined separation block 16 shakes, the plastic particles can be dropped into the collection base 2 below, thereby saving processing costs.
