Description

Technical Field

[0001] The invention relates to the field of plastic granulators, in particular to polyethylene hot-cutting granulation equipment. 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. The plastic granulator is mainly used to process waste plastic films, woven bags, agricultural convenience bags, basins, barrels, beverage bottles, furniture, daily necessities, etc. It is suitable for most common waste plastics and is the most widely used in the waste plastic recycling industry.

[0003] The existing polyethylene hot cutting granulation equipment mainly has the following problems: 1. The polyethylene hot cutting granulation equipment is used for recycling polyethylene plastic. The polyethylene plastic in the molten state is cut into granules by hot cutting. In the cutting process, the polyethylene plastic is easy to adhere to the cutter because it is in a high temperature state. The tool with impurities is formed in the subsequent hot cutting process because the material cut by the blade is not effectively separated from the cutter, which may cause abnormal snake skin particles; 2. Before starting and after shutting down the machine, the adhered materials or impurities on the tool need to be cleaned to facilitate the next work of the tool. The blade of the tool is the key cleaning position. Since the blade itself is too sharp, it may accidentally cut the staff during cleaning, and the gap between the blade and the mold plate is too small, which is extremely inconvenient to clean; therefore, we propose a polyethylene hot cutting granulation equipment. Summary of the invention

[0004] In view of the problem in the prior art that the cutting blade is easy to adhere to materials and is difficult to clean, the present invention provides a polyethylene hot cutting granulation equipment.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a polyethylene hot cutting granulation equipment, including a base, a feeding component, a feeding hopper, a hot cutting component and a collecting hopper;

[0006] A feeding assembly is provided on the top of the base, a feeding hopper is provided on the top of the feeding assembly, a hot cutting assembly is fixedly connected to one side of the feeding assembly, and a collecting hopper is provided on the rear side of the base;

[0007] A delivery pipe is provided between the hot cutting assembly and the collecting hopper;

[0010] A slider is movably connected to the inner side of the shell top, a telescopic column is fixedly sleeved on the inner side wall of the slider top, a connecting plate is fixedly installed on the outer wall of one side of the device shell, a water bottle is fixedly sleeved on the inner side of the connecting plate, and a bottle mouth is fixedly connected to the bottom of the water bottle.

[0011] Specifically, the cutter disc is fixedly sleeved on the outer side wall of the rotating shaft, and a rolling bearing is arranged between the shell and the rotating shaft.

[0012] Specifically, an inner wall on one side of the shell is fixedly connected to a limiting bracket, and the rotating pin is movably sleeved on the inner wall at the top of the limiting bracket.

[0013] Specifically, a slide groove is provided at a position on the inner side of the shell corresponding to the slider, and a telescopic spring is provided between the shell and the slider, and two ends of the telescopic spring are respectively fixed on opposite sides of the shell and the slider.

[0014] Specifically, a balancing air pipe is connected through the front side of the water bottle, and a through hole is opened at a position inside the bottle mouth corresponding to the telescopic column.

[0015] Specifically, a rotating handle is movably sleeved on the inner side of the cutter disc, a winch is fixedly sleeved on the outer side wall of the middle part of the rotating handle, a cutting steel rope is provided on the outer side wall of the winch, an L-shaped plate is fixedly connected to the outer side wall of the cutter disc, and a fixing seat is provided on the inner side of the top of the L-shaped plate.

[0016] Specifically, a cleaning sheet is movably connected to the bottom of the fixed seat, a torsion spring is provided at the connection between the cleaning sheet and the fixed seat, a fixing column is fixedly connected to the outer wall of the knife disc, the cutting steel rope passes through the fixing column and the fixed seat, and a fixing pin is provided between the fixed seat and the L-shaped plate.

[0017] Specifically, a torsion spring is provided at the connection between the cleaning sheet and the fixing seat.

[0018] Beneficial effects of the present invention:

[0019] (1) The polyethylene hot cutting granulation equipment described in the present invention is connected to the motor output shaft through a rotating shaft. The motor output shaft drives the rotating shaft to rotate, which drives the first bevel gear on the rotating shaft to rotate, so that the second bevel gear meshing with the first bevel gear rotates together, driving the elliptical disk on the rotating pin to rotate. The rotation of the elliptical disk drives the slider on one side of the elliptical disk to move, so that the telescopic column on the slider reciprocates and retracts. When the telescopic column is inserted into the through hole of the bottle mouth, water will not flow in the water bottle. If the telescopic column is separated from the bottle mouth, water will flow out of the bottle mouth of the water bottle. Since the displacement speed of the slider is fast and the displacement stroke is short, water droplets will form a thin stream to flush the cutting steel rope. The water droplets adhere to the cutting steel rope, and the cutting steel rope will not easily adhere to the material, thereby avoiding the generation of abnormal snake skin particles and improving the yield rate.

[0020] (2) The polyethylene hot cutting granulation equipment described in the present invention retracts and retracts the cutting steel rope by rotating the capstan, a fixing pin is provided on the inner side of the top of the L-shaped plate, and a corresponding fixing seat is also provided on the top of the cutting steel rope. The fixing seat is inserted into the top plate of the L-shaped plate and locked with the fixing pin to cut the material extruded from the template. The cutting steel rope can be retracted by reversing the capstan, and when the fixing seat at the top of the cutting steel rope is retracted, impurities attached to the outer surface of the cutting steel rope will adhere to the outer surface of the fixing column. When the fixing seat contacts the fixing column, the cleaning sheet at the bottom of the fixing seat will fork to clean the impurities collected on the outer surface of the fixing column. The impurities attached to the cutting steel rope can be cleaned before and after use, which is more convenient to clean than traditional cutting tools. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] like Figure 1-Figure 6 As shown, a polyethylene hot cutting granulation device of the present invention comprises a base 1, a feeding assembly 2, a feeding hopper 3, a hot cutting assembly 6 and a collecting hopper 4;

[0031] A feeding assembly 2 is provided on the top of the base 1, a feeding hopper 3 is provided on the top of the feeding assembly 2, a hot cutting assembly 6 is fixedly connected to one side of the feeding assembly 2, a collecting hopper 4 is provided on the rear side of the base 1; a conveying pipe 5 is provided between the hot cutting assembly 6 and the collecting hopper 4;

[0033] The hot cutting component 6 includes a device shell 601, the inner wall of the device shell 601 is fixedly sleeved with a template 611, one side of the template 611 is provided with a mold hole 622, the center inner wall of the template 611 is movably sleeved with a rotating shaft 603, one side of the template 611 is provided with a knife disc 626, and one side of the knife disc 626 is provided with a shell 602; the outer wall of the rotating shaft 603 is fixedly sleeved with a first bevel gear 612, the top of the first bevel gear 612 is meshed with a second bevel gear 619, the center inner wall of the second bevel gear 619 is fixedly sleeved with a rotating pin 613, the outer wall of the rotating pin 613 and the top of the limiting bracket 625 are fixedly sleeved with an elliptical disk 618; the inner side of the top of the shell 602 is movably connected with a slider 610, the inner wall of the top of the slider 610 is fixedly sleeved with a telescopic column 609, and the outer wall of one side of the device shell 601 is fixedly installed with a connecting plate 605, connecting A water bottle 606 is fixedly sleeved on the inner side of the plate 605, a bottle mouth 608 is fixedly connected to the bottom of the water bottle 606, and the front side of the water bottle 606 is penetrated, a knife disc 626 is fixedly sleeved on the outer side wall of the rotating shaft 603, a rolling bearing is arranged between the shell 602 and the rotating shaft 603, a limiting bracket 625 is fixedly connected to the inner wall of one side of the shell 602, a rotating pin 613 is movably sleeved on the inner side wall of the top of the limiting bracket 625, a sliding groove is provided on the inner side of the shell 602 at a position corresponding to the slider 610, and a telescopic spring 604 is provided between the shell 602 and the slider 610, and two ends of the telescopic spring 604 are respectively fixed on the opposite sides of the shell 602 and the slider 610, a balancing air pipe 607 is penetrated on the front side of the water bottle 606, a through hole is provided on the inner side of the bottle mouth 608 at a position corresponding to the telescopic column 609, and a cutting steel rope 616 is arranged on the outer side wall of the capstan 623;

[0034] During the material cutting process, since the rotating shaft 603 is fixedly connected to the output shaft of the motor (not shown in the figure), the output shaft of the motor will drive the rotating shaft 603 to rotate during operation. The outer wall of the rotating shaft 603 is fixedly sleeved with the first bevel gear 612, and the first bevel gear 612 and the second bevel gear 619 are meshed with each other. The first bevel gear 612 rotates with the rotation of the rotating shaft 603, driving the second bevel gear 619 to rotate. The inner side of the second bevel gear 619 is fixedly sleeved with a rotating pin 613, so the rotating pin 613 rotates with the rotation of the second bevel gear 619. Because the second bevel gear 619 and the elliptical disk 618 use the rotating pin 613 as a common axis, the rotating pin 613 drives the elliptical disk 618 to rotate. A slider 610 is slidably connected to the corresponding position of the elliptical disk 618 on the top inner side of the shell 602, and a telescopic spring 604 is provided between the slider 610 and the shell 602. When the elliptical disk 618 rotates 180° from the original position, the elliptical disk 618 will push the slider 610 to one side, and the telescopic column 609 on the slider 610 will be inserted into the through hole corresponding to the bottle mouth 608. At this time, the water in the water bottle 606 will not fall. When the elliptical disk 618 is rotated 180 degrees again and resets, the telescopic spring 604 will drive the slider 610 to reset. At this time, the telescopic column 609 will be separated from the bottle mouth 608, and the water in the water bottle 606 will fall. Due to the high speed of the rotating shaft 603, the reciprocating cycle of the slider 610 will be shortened. The water flow in the water bottle 606 will form a thin stream to wash the cutting steel rope 616. The cutting steel rope 616 will not easily adhere to the material after being stained with water, thereby preventing the formation of snake skin particles. In addition, when the granulation equipment is not working, that is, the rotating shaft 603 stops rotating, the telescopic column 609 is in the through hole inserted into the bottle mouth 608, which can prevent the water from flowing down. The water in the water bottle 606 depends on the work of the rotating shaft 603, and no additional controller is required, which saves water resources and costs at the same time.

[0035] A rotating handle 624 is movably sleeved on the inner side of the cutter disc 626, a capstan 623 is fixedly sleeved on the outer wall of the middle part of the rotating handle 624, an L-shaped plate 617 is fixedly connected to the outer wall of the cutter disc 626, a fixing seat 614 is arranged on the inner side of the top of the L-shaped plate 617, a cleaning sheet 615 is movably connected to the bottom of the fixing seat 614, a torsion spring is arranged at the connection between the cleaning sheet 615 and the fixing seat 614, a fixing column 621 is fixedly connected to the outer wall of the cutter disc 626, a cutting steel rope 616 passes through the fixing column 621 and the fixing seat 614, and a fixing pin 620 is arranged between the fixing seat 614 and the L-shaped plate 617;

[0036] Before and after the cutting wire rope 616 works, the fixed column 621 on the cutter disc 626 can be used to clean the impurities on the cutting wire rope 616, which is convenient for subsequent work. The specific cleaning process is that the rotating handle 624 is manually twisted to drive the winch 623 on the outside of the rotating handle 624 to rotate. Since the outer side of the winch 623 is sleeved with the cutting wire rope 616, the rotation of the winch 623 can drive the cutting wire rope 616 to retract. When the cutting wire rope 616 is retracted into the cutter disc 626, the fixed seat 614 at the top of the cutting wire rope 616 will contact the fixed column 621 on the outer wall of the cutter disc 626. Since the bottom of the fixed seat 614 is movably connected with a cleaning sheet 615, after the contact, the cleaning sheet 615 is due to the top of the fixed column 621 (the top of the fixed column 621 is conical). 616 is opened due to the squeezing force of the cutting steel rope 616. When the cutting steel rope 616 is retracted, the impurities on the outer surface of the cutting steel rope 616 are in contact and friction with the fixing column 621 and are left on the outer surface of the fixing column 621. After the cleaning sheet 615 is opened, the outer surface of the fixing column 621 is cleaned to prevent the adhesion of impurities. When the fixing column 621 is separated from the fixing seat 614, the cleaning sheet 615 is reset under the action of the torsion spring. Compared with the traditional hot cutting knife, this method is more conducive to cleaning by the staff. When the cutting steel rope 616 is needed, the capstan 623 is rotated in the opposite direction to stretch the cutting steel rope 616 to the longest, and then the fixing seat 614 at the top of the cutting steel rope 616 is inserted into the inner side of the top of the L-shaped plate 617, and the fixing seat 614 is locked by the fixing pin 620.

[0037] Working principle:

[0038] Tool cleaning process:

[0039] The rotation of the rotating shaft 603 drives the first bevel gear 612 on the rotating shaft 603 to rotate, and the first bevel gear 612 drives the second bevel gear 619 to rotate, driving the elliptical disk 618 on the rotating pin 613 to rotate and push the corresponding slider 610 outward, and then the slider 610 is reset with the help of the telescopic spring 604, and the slider 610 reciprocates to drive the telescopic column 609 inside the slider 610 to reciprocate and retract. Since the telescopic column 609 corresponds to the through hole of the bottle mouth 608, the telescopic column 609 reciprocates in the through hole, so that the water flow in the water bottle 606 is deformed into a thin stream, and the water flow is attached to the cutting steel rope 616, so that the cutting steel rope 616 will not easily adhere to the material, thereby preventing the appearance of snake skin particles, and the water flow works with the operation of the equipment to maintain synchronization, saving water resources and costs;

[0040] Cleaning process before and after tool work:

[0041] When the cutting steel rope 616 needs to be cleaned before and after use, the cutting steel rope 616 is driven to retract and retract by the rotation of the winch 623. When the cutting steel rope 616 retracts, impurities on the cutting steel rope 616 are scraped off by the fixed column 621 and attached to the surface of the fixed column 621. When the fixed column 621 contacts the fixed seat 614, the cleaning sheet 615 at the bottom of the fixed seat 614 is unfolded to scrape out the impurities on the surface of the fixed column 621, so as to facilitate the use of the cutting steel rope 616.
