Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and in particular to a raw material cleaning device for the production of plastic products. Background Technology

[0002] The production of PPH extra-large plastic tanks involves melting PPH granules on a spiral extrusion winding machine, then forming the tank body on a mold. Once the temperature drops to a certain level, the tank can be demolded to ensure its integrity.

[0003] Before melting, PPH granules generally need to be cleaned to remove dust and other impurities adhering to the surface of the granules, thereby ensuring the quality of the finished products in subsequent processing. However, during cleaning, the granules are light in weight and tend to float on the surface of the liquid, which can lead to insufficient cleaning and affect the cleaning effect. Summary of the Invention

[0004] The purpose of this invention is to provide a raw material cleaning device for the production of plastic products.

[0005] The technical problem of this invention is mainly solved by the following technical solution:

[0006] A raw material cleaning device for plastic product manufacturing includes a tank:

[0007] The barrel is a square barrel, and a forward and reverse lead screw I driven by a motor is installed inside the barrel. Filter plates are installed at both the upper and lower ends of the forward and reverse lead screw I. A screw tube is installed on the filter plate and screwed to the forward and reverse lead screw I. A sleeve connected to the screw tube through a bearing is sleeved on one end of the screw tube and the sleeve is located between the upper and lower filter plates. A horizontal bar connected to the inner wall of a ring is radially installed on the outer wall of the sleeve. Vertical bars are evenly arranged on the horizontal bar and the corresponding vertical bars are staggered. Gear teeth I are axially arranged on the outer wall of the ring. A gear rod that meshes with the gear teeth I is vertically installed inside the barrel. The gear rod passes through the filter plate and is fixed to the upper and lower side walls of the barrel through bearings. A transmission gear I is installed at the top of the gear rod. A toothed ring is installed between multiple sets of transmission gears I and meshes with them. The toothed ring is connected to the forward and reverse lead screw I through a connecting rod.

[0008] The outer side of the barrel is also provided with a pneumatic agitation mechanism corresponding to the gear rod. The pneumatic agitation mechanism includes a housing, and an air bladder is provided inside the housing. The air bladder is provided with a one-way air outlet pipe that communicates with the inside of the barrel. Clamping plates are provided in the housing on both the upper and lower sides of the air bladder. A positive and negative lead screw II is provided on the housing, passing through the upper and lower clamping plates. The positive and negative lead screw II is fixed to the top wall of the barrel by bearings. A transmission gear II corresponding to the transmission gear I is provided at the top of the positive and negative lead screw II. A communication opening is provided on the side wall of the barrel to accommodate one end of the corresponding transmission gear I and transmission gear II. The transmission gear I and transmission gear II are meshed together.

[0009] Preferably, the airbag sidewall is provided with an air inlet pipe with a solenoid valve, wherein the airbag is located in the opening formed between the upper and lower clamping plates and the positive and negative lead screws II.

[0010] Preferably, the one-way air outlet is located in the middle between the upper and lower ends of the positive and negative lead screw I, wherein a round tube is fixedly connected to the middle of the positive and negative lead screw I.

[0011] Preferably, the bottom of the barrel is provided with a water outlet pipe located below the filter plate, wherein a feed pipe is provided on the side wall of the barrel at the bottom of the upper filter plate, and a discharge pipe is provided on the side wall of the barrel at the top of the lower filter plate.

[0012] Preferably, the filter plate sidewall is provided with a through hole for the gear rod to pass through, wherein the gear rod is staggered from the one-way air outlet pipe.

[0013] Preferably, the gear rod consists of a round rod and a plurality of gear teeth II axially arranged on the outer wall of the round rod.

[0014] The beneficial effects of this invention are as follows: This invention expands or reduces the distance between two sets of filter plates through mechanical drive, thereby exerting a reciprocating squeezing effect on the material between the two sets of filter plates. The rotating vertical rod also agitates the material inside the tank for cleaning. Simultaneously, the two sets of filter plates clamp and fix the material in the liquid, preventing it from floating on the liquid surface and affecting the cleaning process. When the liquid is discharged from the tank through the outlet pipe after cleaning, the reduced-distance filter plates, while squeezing the material, also accelerate the discharge of liquid from the material. Furthermore, a pneumatic agitation mechanism introduces gas into the tank, blowing and agitating the internal material and liquid, thereby improving the cleaning efficiency and effect.

[0020] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0021] A raw material cleaning device for plastic product manufacturing includes a tank 1:

[0022] The barrel 1 is a square barrel, and a forward and reverse lead screw I3 driven by a motor 2 is installed inside the barrel 1. Filter plates 4 are installed at both ends of the forward and reverse lead screw I3. A screw tube 5 is screwed onto the filter plate 4 and connected to the forward and reverse lead screw I3. A sleeve 6 connected to the sleeve 5 via a bearing is sleeved on one end of the sleeve 5, and the sleeve 6 is located between the upper and lower filter plates 4. A horizontal bar 7 is radially arranged on the outer wall of the sleeve 6 and connected to the inner wall of a circular ring 9. Vertical bars 8 are evenly arranged on the horizontal bar 7, and the corresponding vertical bars 8 are staggered. The circular ring 9... A gear tooth I10 is axially arranged on the outer wall. A gear rod 11 that meshes with the gear tooth I10 is vertically arranged inside the barrel 1. The gear rod 11 passes through the filter plate 4 and is fixed to the upper and lower side walls of the barrel 1 by bearings. The gear rod 11 is composed of a round rod 111 and several gear teeth II112 axially arranged on the outer wall of the round rod 111. A transmission gear I12 is arranged at the top of the gear rod 11. A toothed ring 13 that meshes with the multiple sets of transmission gears I12 is arranged between them. The toothed ring 13 is connected to the positive and negative lead screw I3 through the connecting rod 14.

[0023] The outer side of the barrel 1 is also provided with a pneumatic agitation mechanism 15 corresponding to the gear rod 11. The pneumatic agitation mechanism 15 includes a housing 151. An air bladder 152 is provided inside the housing 151. A one-way air outlet pipe 153 communicating with the inside of the barrel 1 is provided on the air bladder 152. Clamping plates 154 are provided in the housing 151 on both the upper and lower sides of the air bladder 152. A positive and negative lead screw II 155 passing through the upper and lower clamping plates 154 is provided on the housing 151. The positive and negative lead screw II 155 is fixed to the top wall of the barrel 1 by bearings. A transmission gear II 156 corresponding to the transmission gear I 12 is provided at the top of the positive and negative lead screw II 155. A communication opening 157 for accommodating one end of the corresponding transmission gear I 12 and transmission gear II 156 is provided on the side wall of the barrel 1. The transmission gear I 12 and transmission gear II 156 are meshed together.

[0024] In this embodiment, an air inlet pipe with a solenoid valve is provided on the side wall of the airbag 152, wherein the airbag 152 is located in the opening formed between the upper and lower sets of clamping plates 154 and the positive and negative lead screws II 155.

[0025] like Figure 2 As shown, the one-way air outlet pipe 153 is located in the middle between the upper and lower ends of the positive and negative lead screw I3, and the positive and negative lead screw I3 is fitted with a round pipe 16 that is fixedly connected to it.

[0026] In this embodiment, a water outlet pipe is provided at the bottom of the barrel 1 below the filter plate 4, and a feed pipe is provided on the side wall of the barrel 1 at the bottom of the upper filter plate 4, and a discharge pipe is provided on the side wall of the barrel 1 at the top of the lower filter plate 4.

[0027] In this embodiment, a through hole for the gear rod 11 to pass through is provided on the side wall of the filter plate 4, wherein the gear rod 11 is staggered from the one-way air outlet pipe 153.

[0028] The method of using this invention is as follows: The material is introduced into the space between two sets of filter plates 4 through the feed pipe and is immersed and cleaned by liquid. At this time, the forward or reverse motor 2 drives the forward and reverse screw I3 to rotate in the screw tube 5, thereby driving the corresponding filter plate 4 to move up and down reciprocally. During this process, the filter plate 4 drives the ring 9 and the gear tooth I10 to slide up and down on the gear rod 11 through the screw tube 5, sleeve 6 and cross bar 7. At the same time, the gear tooth I10 will not separate from the gear rod 11. At this time, the square structure of the barrel 1 can hold the filter plate 4 to prevent it from rotating together with the forward and reverse screw I3, thereby expanding or reducing the distance between the two sets of filter plates 4, thereby exerting a reciprocating squeezing effect on the material between the two sets of filter plates 4 to clean it. At the same time, the material is clamped and fixed in the liquid by the two sets of filter plates 4 to prevent the material from floating on the liquid surface and affecting its cleaning work. After the cleaning is completed, when the liquid in the barrel 1 is discharged through the water outlet pipe, the reduced distance of the filter plate 4 can also accelerate the discharge of liquid from the material when squeezing the material.

[0029] Meanwhile, when the positive and negative lead screws I3 rotate, they drive the transmission gear I12 through the connecting rod 14 and the gear ring 13 to drive the gear rod 11 to rotate. The gear rod 11 then drives the ring 9 to rotate through the gear teeth I10. At this time, the ring 9 drives the sleeve 6 to rotate on the bearing outside the screw tube 5 through the crossbar 7. During this process, the rotating crossbar 7 will drive the corresponding vertical rod 8 to rotate inside the barrel 1 to agitate the material between the two sets of filter plates 4. Because the upper and lower corresponding vertical rods 8 are staggered, they interfere with each other during rotation.

[0030] When the transmission gear I12 rotates, it drives the positive and negative lead screws II155 to rotate through the transmission gear II156. When the positive and negative lead screws II155 rotate in the screw holes on the clamping plates 154, they can increase or decrease the distance between the two sets of clamping plates 154. During this process, the side wall of the housing 151 clamps the clamping plates 154 to prevent them from rotating together with the positive and negative lead screws II155. When the distance between the two sets of clamping plates 154 decreases, the air bag 152 can be compressed so that the gas inside can enter the barrel 1 through the one-way air outlet pipe 153 to blow the material and liquid inside, thereby causing a surge. While the material and liquid inside the barrel 1 are pneumatically agitated, the cleaning efficiency and effect of the material are improved. When the distance between the two sets of clamping plates 154 increases, the solenoid valve on the air inlet pipe is opened so that the outside gas can enter the air bag 152 to fill it, in preparation for the next pneumatic agitation of the barrel 1.

[0031] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
