[0002] Granulator is a molding machine that can make materials into specific shapes. It is widely used in chemical, petrochemical, pharmaceutical, food, building materials, mining, environmental protection, printing and dyeing, ceramics, rubber, plastics and other fields. The recycling and resource development of waste plastics is a production method that stems from a deep understanding of the environment and resources, reduces the pollution of waste plastics to the environment and reduces the waste of resources, and realizes the recycling and resource development of waste plastics.

[0003] In the prior art, the granulation equipment uses a mechanical blade cutting method to cut the heated raw materials at the discharge end, and then discharges them into a cooling water pool after cutting, and then the finished particles are collected uniformly. During the cutting, since the heated raw materials are in an incompletely cooled state, when the blade cuts the basic plastic strip, part of the semi-solid raw materials on the cut surface of the plastic strip will adhere to the blade, causing scraping between the blade and the cut surface of the plastic strip, resulting in wire drawing on the cut surface of the plastic strip and affecting the quality of the particles.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0024] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0026] See also Figure 1-3 As shown, the utility model is an engineering plastic granulator, comprising a base 1, an extrusion mechanism 2 is fixedly installed on the upper surface of the base 1, a discharge mold 3 is fixedly installed at one end of the extrusion mechanism 2, a cooling water pool 5 is provided below the discharge mold 3, a driving component 6 is fixedly installed on one side of the cooling water pool 5, a cutting component 7 is fixedly installed on one side of the driving component 6, and the cutting component 7 is fitted with the discharge mold 3, and scraper tooling 8 is fixedly installed on the upper and lower surfaces of the discharge mold 3, and the blade surface of the scraper tooling 8 is parallel to the discharge surface of the discharge mold 3.

[0027] The discharge surface of the discharge mold 3 is provided with a discharge hole, and the blade surface of the scraper tooling 8 is conical.

[0028] When in use, the extruder transports the plastic raw material from the hopper above the barrel into the barrel. The barrel is composed of a screw and a spiral path, and then heated and pressurized to allow the material to flow continuously through the screw in the barrel. In order to have sufficient pressure, the depth of the screw thread decreases as the distance from the hopper increases until it is sent to the other end of the barrel. This extruder belongs to the existing technology and will not be elaborated on in detail.

[0029] Since a cutting component 7 is fixedly installed on one side of the output shaft of the driving component 6, when the heated plastic raw material is extruded through the discharging mold 3, the driving component 6 is started, and the driving component 6 drives the cutting component 7 to cut the heated plastic raw material up and down through reciprocating motion. Since a scraper tooling 8 is fixedly installed on the upper and lower surfaces of the discharging mold 3, and the blade surface of the scraper tooling 8 is parallel to the discharging surface of the discharging mold 3, when the driving component 6 drives the cutting component 7 to reciprocate, the blade surface of the scraper tooling 8 moves along the side of the cutting component 7 to clean the surface of the cutting component 7.

[0030] The utility model fixes the scraper tooling 8 on the upper and lower surfaces of the discharging mold 3, so that when the driving component 6 drives the cutting component 7 to reciprocate up and down, the side surface of the cutting component 7 is scraped by the blade surface of the scraper tooling 8, thereby solving the problem that when the blade cuts the basic plastic strip, part of the semi-solid raw material on the cut surface of the plastic strip will adhere to the blade, causing scraping between the blade and the cut surface of the plastic strip, resulting in wire drawing on the cut surface of the plastic strip and affecting the quality of the particles.

[0031] In one embodiment, for the above-mentioned driving assembly, the driving assembly 6 includes a driving cylinder 19 , a fixing block 9 is fixedly mounted on the output end of the driving cylinder 19 , and a cutting assembly 7 is fixedly mounted on one side of the fixing block 9 .

[0032] When in use, the cylinder 19 is driven to drive the fixed block 9 fixedly installed at its output end to move up and down reciprocatingly, so that the cutting assembly 7 connected to the fixed block 9 moves up and down reciprocatingly.

[0033] In one embodiment, for the above-mentioned cutting assembly, the cutting assembly 7 includes a cutter 10 , and the cutter 10 is fixedly mounted on one side of the fixing block 9 .

[0034] During use, since the cutter 10 is fixedly mounted on the fixed block 9 , when the driving cylinder drives the fixed block to move, the fixed block 9 drives the cutter 10 to move, so that the cutter 10 cuts the raw material extruded by the discharge die 3 .

[0035] In one embodiment, for the scraper tooling mentioned above, the scraper tooling 8 includes a conical scraper 11 , and the conical scraper 11 is arranged on the discharge mold 3 .

[0036] In specific applications, the conical scraper can be slidably set on the discharge mold, and a pillar is fixedly installed on one side of the conical scraper. The outer surface of the pillar is sleeved with a spring, and one end of the spring is clamped on the discharge mold. The conical scraper is perpendicular to the blade surface of the cutter. When the conical scraper is pushed upward by the cutter, the conical scraper is squeezed downward by the spring, thereby increasing the force of the conical scraper on the cutter, which is more conducive to the conical scraper to cut the raw material on the surface of the cutter.

[0037] In one embodiment, for the drainage tube, a drainage hole 12 is opened at one end of the base 1 , and a drainage tube 13 is fixedly mounted on the drainage hole 12 .

[0038] In one embodiment, for the above-mentioned cooling water pool, an oscillation plate 14 is installed inside the cooling water pool 5, and a plurality of support columns 15 are installed on the bottom surface of the oscillation plate 14. The support columns 15 are sleeved with a plurality of limit plates 16, and the limit plates 16 are fixedly connected to the inner wall of the cooling water pool 5, and a spring 17 is sleeved on the outer surface of the support column 15, and one end of the spring 17 is in contact with the bottom surface of the oscillation plate 14, and the other end is in contact with the upper surface of the limit plate 16, and an oscillation motor 18 is fixedly installed at the bottom of the cooling water pool 5.

[0039] During use, when the oscillation motor 18 is started, the oscillation motor 18 causes the oscillation plate 14 to vibrate. Since the outer surface of the support column 15 is sleeved with a spring 17, and one end of the spring 17 is in contact with the bottom surface of the oscillation plate 14, the spring 17 is used to increase the vibration amplitude of the oscillation plate 14, so that the plastic particles falling on the oscillation plate 14 shake in the water. At the same time, the impact of the water flow on the plastic particles is used to prevent the plastic particles from sticking.

[0040] In one embodiment, for the cooling water pool, an inclined plate 4 is fixedly mounted on the inner wall of the cooling water pool 5 .

[0041] When in use, since the inner wall of the cooling water pool 5 is fixedly mounted with the inclined plate 4, after the heated material is cut by the cutter 10, it enters the cooling water pool 5 through the inclined plate 4, thereby playing a buffering role for the heated material.

[0042] In summary, with the aid of the above technical solution of the utility model, when the extruder extrude the plastic raw material from the discharge die 3, the driving cylinder 19 is started, and the driving cylinder 19 drives the fixed block 9 fixedly installed at its output end to move up and down reciprocatingly, so that the cutter 10 connected to the fixed block 9 reciprocates up and down to cut the heated material. Since the upper and lower surfaces of the discharge die 3 are fixedly installed with a conical scraper 11, and the blade surface of the conical scraper 11 is parallel to the discharge surface of the discharge die 3, when the driving component 6 drives the cutting component 7 to reciprocate, the blade surface of the conical scraper 11 cuts the heated material. The side of the material assembly 7 is scraped; the cutter 10 cuts off the raw material extruded by the discharge die, and the cut raw material particles slide into the cooling water pool 5 through the inclined plate 4 fixedly installed on the inner wall of the cooling water pool 5. At the same time, the oscillation motor 18 makes the oscillation plate 14 vibrate. Since the outer surface of the support column 15 is sleeved with a spring 17, and one end of the spring 17 is in contact with the bottom surface of the oscillation plate 14, the spring 17 is used to increase the vibration amplitude of the oscillation plate 14, so that the plastic particles falling on the oscillation plate 14 shake in the water. At the same time, the impact of the water flow on the plastic particles is used to prevent the plastic particles from sticking.

[0043] Through the above technical scheme, 1. The utility model fixes the scraper tooling 8 on the upper and lower surfaces of the discharging mold 3, so that when the driving component 6 drives the cutting component 7 to reciprocate up and down, the side of the cutting component 7 is scraped by the blade surface of the scraper tooling 8, thereby solving the problem that when the blade cuts the basic plastic strip, part of the semi-solid raw material on the cutting surface of the plastic strip will adhere to the blade, causing scraping between the blade and the cutting surface of the plastic strip, resulting in wire drawing on the cutting surface of the plastic strip and affecting the quality of the particles; 2. When the oscillation motor 18 is started, the oscillation motor 18 causes the oscillation plate 14 to vibrate. Since the outer surface of the support column 15 is sleeved with a spring 17, and one end of the spring 17 is in contact with the bottom surface of the oscillation plate 14, the spring 17 is used to increase the vibration amplitude of the oscillation plate 14, so that the plastic particles falling on the oscillation plate 14 shake in the water. At the same time, the impact of the water flow on the plastic particles is used to prevent the plastic particles from sticking.
