[0019] The present invention also discloses a processing method of PP plastic particle processing equipment, comprising the following steps:

[0020] S1, material preparation and equipment power-on inspection. Before production, PP plastic particles are first prepared according to the required amount of production and processing shape;

[0021] S2, material addition, PP plastic particles are pre-stored in the Jiaolong conveyor and the inside of the feeding port through the feeding port in the feeding mechanism, and driven by the driving motor A, the PP plastic particles are sent to the inside of the cylindrical heater through the material conveying pipe and the cylindrical heater;

[0022] S3, heating and melting, the cartridge heater is powered on, and the cartridge heater heats the PP plastic particles inside within its melting temperature range to transform them into a plastic state;

[0023] S4, discharge extrusion, after the cylindrical heater heats the PP plastic particles for a predetermined time and the PP plastic particles are in a plastic state, the two drive motors B drive the rotation of the drive shaft. During the rotation of the drive shaft, the internal thread slider moves horizontally, and the extrusion assembly A is driven to move synchronously through the retractable connecting component. During the movement of the extrusion plate, the melted PP plastic is extruded. During the continuous inward movement of the extrusion plate, the plastic PP plastic falls downward through the conduit into the storage tank for collection;

[0024] S5, adding materials to the mold. When the extrusion plate completely extrude the PP plastic in the cylindrical heater, the multiple mold brackets are carried and transported forward by the conveying component. The molding molds on the top of the multiple mold brackets are transported forward in turn and correspond to the extrusion tube under the transportation of the conveying component. When each molding mold corresponds to the extrusion tube, the telescopic cooperation of the movable cavity and the telescopic column can further extend the distance that the telescopic connection component continues to move backward, so that the internal thread slider can drive the pressing plate A and the pressing plate B to move synchronously through the "L"-shaped extension connecting piece, corresponding to the position of the storage tank. At this time, the lifting cylinder drives the driving motor B to fall through the fixed plate. During the falling process, the pressing plate B moves downward along the inner wall of the storage tank and squeezes the PP plastic in a plastic state downward into each molding mold.

[0025] S6, cooling and demoulding, the cooling system on the mold support cools and solidifies the PP plastic product in the molding mold. After the PP plastic product is completed and the temperature is stable, the molded PP plastic product is extruded by the demoulding tool equipment to complete the production of the PP plastic product.

[0026] Compared with the prior art, the present invention provides a PP plastic particle processing equipment and a processing method thereof, which have the following beneficial effects:

[0027] 1. The cylindrical heater in the heating extrusion mechanism collects the PP particles through the feed port at the top. The horizontal inward movement of the extrusion assembly A can gradually reduce the space in the cylindrical heater, so that after the PP plastic particles in the cylindrical heater are heated to a plastic state, the plastic PP plastic is discharged downward through the conduit during the extrusion process. The PP plastic particle processing equipment has comprehensive and diverse functions, compact overall structure, and ingenious design. In the production process, the staff only needs to pre-store fillers in the processing equipment. The heating and basic processes are automatically completed by the processing equipment. In use, it can greatly improve the production efficiency of plastic products, which is conducive to promotion and use.

[0028] 2. When the PP plastic in the tubular heater is extruded, two drive motors B provide power. Under the thread cooperation of the drive shaft and the internal thread slider, the drive motor B drives the drive shaft to rotate. During the process, the internal thread slider moves horizontally along the drive shaft, thereby driving the extrusion assembly A to move in the tubular heater to complete the outward extrusion of the plastic PP plastic in the tubular heater. The lifting cylinder in the extrusion assembly B can control the horizontal height of the two drive motors B. Under the telescopic cooperation with the telescopic connection component, the pressure plate B can move down in the storage tank to increase the pressure, and extrude the plastic PP plastic in the storage tank outward.

[0029] 3. During the movement of the extrusion component A, the inner wall of the cylindrical heater is extruded by the extrusion plate. With the cooperation of the limit slide groove and the slide plate, as well as the cooperation of the support and the guide groove, the stability of the extrusion plate during horizontal movement is maintained, thereby improving the outward extrusion effect of the plastic PP plastic in the cylindrical heater. By setting a filter at the top of the conduit, the PP plastic that is still in particle form can be blocked, thereby controlling the quality of the PP plastic extruded outward, thereby improving the quality of product manufacturing.

[0030] 4. There is friction between the active cavity and the telescopic column, so that when the internal thread slider moves horizontally, it can drive the limit cylinder and the extrusion plate to move synchronously without the telescopic column falling out of the active cavity. In this way, when the extrusion plate moves to one end of the inner side of the extrusion plate, the plastic PP plastic is completely extruded outward by the extrusion plate. At this time, when the drive motor B continues to drive the drive shaft, the telescopic column will extend outward from the active cavity. The movement range of the telescopic column is controlled by the cooperation of the limit groove of the active cavity and the limit block of the telescopic column. When the telescopic column extends outward, the limit block contacts one end of the limit groove. The current state is that the telescopic column extends outward to the bottom. At the same time, the pressing plate B just corresponds to the storage tank. At this time, driven by the lifting cylinder, the pressing plate B moves down into the storage tank to increase pressure and extrude the plastic PP plastic in the storage tank outward. It can effectively improve the stability of equipment operation.

[0031] 5. The telescopic connection component is a synchronous connection component between the telescopic column and the internal thread slider. With the cooperation of the limit slide and the connection tube, the overall length of the telescopic connection component can be controlled. When the lifting cylinder drives the pressure plate B to move downward into the storage tank to increase pressure, the overall length of the telescopic connection component is extended through the cooperation of the limit slide and the connection tube, thereby continuously maintaining the connection between the telescopic column and the internal thread slider. When the lifting cylinder drives the drive motor B and the drive shaft to move up and down, the lifting slot can provide a limit function for the drive shaft to prevent it from deflecting.

[0032] 6. Through the scraper on one side of the top of the storage tank, the pressure plate A and the pressure plate B can scrape off the PP plastic residue on the bottom of the rubber pad when they are lifted and reset, so as to avoid the residue from being carried out and affecting the environment of the nearby work area, and solve the problem that the PP plastic residue adheres to the bottom of the rubber pad and is carried out after the extrusion of the plastic PP plastic. The residual material collector on the top of the pressure plate A can collect the residue in the corresponding conduit above it, so as to avoid the residue in the conduit from falling due to natural gravity and affecting the working environment.

[0033] 7. The conveying component can carry multiple mold holders. The molding molds on the top of the mold holder can be set to product molds of different specifications or shapes. After being transported by the conveying component, multiple molding molds correspond to the extrusion tubes in turn. Under the downward pressure drive of the lifting cylinder, the molding mold is filled with plastic PP plastic, and then the cooling system is used to cool and shape the molding mold to complete product production. Before product production and processing, staff will place multiple mold holders on the conveying component in advance to facilitate automated production and processing.

DETAILED DESCRIPTION

[0048] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0049] In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

[0051] The PP plastic particles are fed to the heating extrusion mechanism 9 inside the outer shell 1 through the feeding mechanism 3 outside the outer shell 1.

[0052] Please continue reading Figure 3-5 and Fig. 9 As shown, the heating extrusion mechanism 9 includes a cylindrical heater 10 fixedly installed on the upper part of the inner part of the outer shell 1, a feed port 17 corresponding to the feed mechanism 3 is opened on the top of the cylindrical heater 10, a conduit 21 is fixedly connected to the bottom of one end of the cylindrical heater 10, an extrusion component A11 is arranged inside the cylindrical heater 10, a telescopic connecting part 12 is connected to the top end of the extrusion component A11, a driving shaft 45 is connected to the inner side of two driving motors B41, an internal threaded slider 34 is threadedly connected to the driving shaft 45, an ear piece 35 is fixedly connected to the top of the internal threaded slider 34, and the bottom end of the telescopic connecting part 12 is rotatably connected to the ear piece 35.

[0053] The cylindrical heater 10 in the heating extrusion mechanism 9 collects the PP particle feed through the feed port 17 at the top. The horizontal inward movement of the extrusion assembly A11 will gradually reduce the space in the cylindrical heater 10, so that the PP plastic particles in the cylindrical heater 10 can be heated to a plastic state and the plastic PP plastic can be discharged downward through the conduit 21 during the extrusion process.

[0054] Please continue reading Figure 5 and Figure 6 As shown, a material temporary storage assembly 14 is fixedly installed at the lower part of the outer shell 1, and a storage tank 15 is provided on the upper surface of the material temporary storage assembly 14, and the storage tank 15 receives the plastic PP plastic extruded from the conduit 21. The bottom of the storage tank 15 is fixedly connected to an extrusion pipe 16 that passes downward, and a control valve can be installed on the extrusion pipe 16 according to the use requirements.

[0055] When the plastic PP plastic is extruded, power is provided by two driving motors B41, specifically by the cooperation of the external thread on the driving shaft 45 and the internal thread on the inner wall of the internal thread slider 34. When the driving motor B41 drives the driving shaft 45 to rotate, the internal thread slider 34 will be driven to move horizontally along the driving shaft 45, thereby driving the extrusion assembly A11 to move in the tubular heater 10, thereby completing the outward extrusion of the plastic PP plastic in the tubular heater 10.

[0056] Furthermore, if Fig. 9 and Fig.10As shown, the extrusion assembly B13 includes a support plate 42 fixedly connected to both sides of the material temporary storage assembly 14, a lifting cylinder 43 is fixedly installed on the top of the support plate 42, a fixed plate 44 connected to the drive motor B41 is fixedly connected to the movable end of the top of the lifting cylinder 43, and an "L"-shaped extension connector 37 is fixedly connected to the bottom of the internal thread slider 34. The extrusion assembly B13 controls the horizontal height of the two drive motors B41 through the lifting cylinder 43, the top of the internal thread slider 34 is connected to the bottom of the telescopic connection component 12 through the ear piece 35, and the bottom of the internal thread slider 34 is connected to the pressing plate A38 and the pressing plate B39 through the "L"-shaped extension connector 37. Driven by the lifting and lowering of the lifting cylinder 43 and the telescopic cooperation with the telescopic connection component 12, after the pressing plate B39 corresponds to the storage tank 15, the pressing plate B39 moves downward in the storage tank 15 to increase the pressure, and the plastic PP plastic in the storage tank 15 is extruded outward.

[0057] Among them, a rubber pad 40 can be fixedly connected to the lower surface of the pressing plate B39, and the rubber pad 40 can improve the sealing effect and stability of the pressing plate B39 when it moves up and down in the storage tank 15.

[0058] Specifically, Figure 2 As shown, as a type of feeding mechanism 3, the feeding mechanism 3 can include a mounting plate 4, a driving motor A5, a Jiaolong conveyor 6, a feeding port 7 and a material conveying pipe 8, the mounting plate 4 is fixedly connected to the top of the outer shell 1, the driving motor A5 is installed on the mounting plate 4, the Jiaolong shaft in the Jiaolong conveyor 6 is fixedly connected to the rotating shaft of the driving motor A5, one end of the material conveying pipe 8 is connected to the output end of the Jiaolong conveyor 6, and the other end of the material conveying pipe 8 corresponds to the feeding port 17 of the tubular heater 10.

[0059] Please continue reading Figure 2-4 As shown, the PP plastic particles can be pre-stored for use before being heated through the feed port 7 and the Jiaolong conveyor 6. When in use, the PP plastic particles are conveyed into the feed port 17 of the tubular heater 10 through the cooperation of the driving motor A5, the Jiaolong conveyor 6, and the material conveying pipe 8.

[0060] For details, please continue to refer to Figure 5 , Figure 7 and Figure 8As shown, the extrusion assembly A11 includes an extrusion plate 20 adapted to the inner wall of the cylindrical heater 10, a guide groove 46 is provided at the top of the cylindrical heater 10, a slide plate 19 is fixedly connected to the top of the extrusion plate 20, a limiting slide groove 18 adapted to the slide plate 19 is provided on one side of the cylindrical heater 10, a support member 22 adapted to the guide groove 46 is fixedly connected to the top of the slide plate 19, a limiting cylinder 23 is fixedly connected to the middle of the support member 22, a movable cavity 24 is provided inside the limiting cylinder 23, a telescopic column 25 is movably connected inside the movable cavity 24, a limiting groove 26 is provided at the top and bottom of the movable cavity 24, and a limiting block 27 adapted to the limiting groove 26 is fixedly connected to the top and bottom of one end of the telescopic column 25.

[0061] During the movement of the extrusion assembly A11, the inner wall of the tubular heater 10 is extruded by the extrusion plate 20. With the cooperation of the limiting slide groove 18 and the slide plate 19, and the cooperation of the support member 22 and the guide groove 46, the stability of the extrusion plate 20 during horizontal movement can be maintained, so as to improve the extrusion effect of the plastic PP plastic in the tubular heater 10.

[0062] Furthermore, if Figure 8 As shown, a filter screen 58 can be provided at the top of the conduit 21, and the filter screen 58 can block the PP plastic that is still in particle form, thereby improving the quality of the manufactured product.

[0063] Secondly, when the extrusion plate 20 receives the PP plastic particles at the feed port 17 , a part of the extrusion plate 20 is located inside the cylindrical heater 10 to prevent the PP plastic particles from falling out of the cylindrical heater 10 .

[0064] Also, please read Figure 8-10 As shown, there is a certain friction force between the movable cavity 24 and the telescopic column 25, which enables the internal thread slider 34 to drive the limiting cylinder 23 and the extrusion plate 20 to move synchronously when the telescopic column 25 does not escape from the movable cavity 24 when moving horizontally. In this way, when the extrusion plate 20 moves to one end of the inner part of the extrusion plate 20, the plastic PP plastic is completely extruded outward by the extrusion plate 20. At this time, when the driving motor B41 continues to drive the driving shaft 45, the telescopic column 25 will extend outward from the active cavity 24. The movement range of the telescopic column 25 is controlled by the cooperation of the limit groove 26 of the active cavity 24 and the limit block 27 of the telescopic column 25. When the telescopic column 25 extends outward, when the limit block 27 contacts one end of the limit groove 26, the telescopic column 25 is currently in a state of extending outward to the bottom. At the same time, the pressing plate B39 just corresponds to the storage tank 15. At this time, driven by the lifting cylinder 43, the pressing plate B39 moves downward into the storage tank 15 to increase pressure, and the plastic PP plastic in the storage tank 15 is extruded outward. It can effectively improve the stability of equipment operation.

[0065] Specifically, Figure 7and Fig. 9 As shown, as a type of telescopic connecting component 12, the telescopic connecting component 12 can include a node connecting block 28 fixedly connected to a telescopic column 25, the node connecting block 28 is internally rotatably connected to one end of a connecting tube 29, the other end of the connecting tube 29 is provided with a connecting groove 30 extending inwardly, the connecting groove 30 is internally movably connected to a telescopic plate 31, the top of the connecting groove 30 is provided with a limiting slide 32, the upper surface of the telescopic plate 31 is provided with a limiting block 33 adapted to the limiting slide 32, the bottom end of the telescopic plate 31 is fixedly connected to a rotating column 36, and the telescopic plate 31 is rotatably connected to the ear piece 35 through the rotating column 36.

[0066] The telescopic connecting component 12 serves as a synchronous connecting component between the telescopic column 25 and the internally threaded slider 34. With the cooperation of the limiting slide 32 and the connecting tube 29, the overall length of the telescopic connecting component 12 can be controlled. Specifically, when the lifting cylinder 43 drives the pressure plate B39 to move downward into the storage trough 15 to increase the pressure, the overall length of the telescopic connecting component 12 is extended through the cooperation of the limiting slide 32 and the connecting tube 29, and at the same time, the connection between the telescopic column 25 and the internally threaded slider 34 can be continuously maintained stable.

[0067] Furthermore, if Fig.10 As shown, a vertical plate 47 is fixedly connected to the upper surface of the support plate 42, and a lifting groove 48 corresponding to the driving shaft 45 is opened on the vertical plate 47. When the lifting cylinder 43 drives the driving motor B41 and the driving shaft 45 to move up and down, the lifting groove 48 provides a limiting function for the driving shaft 45 to prevent it from deflecting.

[0068] In this embodiment, further, Fig.11 As shown, in order to solve the problem of PP plastic residue attached to the bottom surface of the rubber pad 40 and carried out after the extrusion of the plastic PP plastic, a scraper 49 is fixedly connected to the top side of the storage tank 15. The scraper 49 can scrape off the PP plastic residue on the bottom surface of the rubber pad 40 when the pressing plate A38 and the pressing plate B39 are lifted and reset, so as to avoid the residue being carried out and affecting the environment of the nearby working area.

[0069] Furthermore, if Fig. 9 As shown, a placement groove 56 is also opened on the top of the pressing plate A38, and a residual material collector 57 is arranged inside the placement groove 56. When the lifting cylinder 43 drives the pressing plate A38 and the pressing plate B39 to move downward for extrusion, the residual material collector 57 can collect the residues in the corresponding conduit 21 above them, thereby avoiding the problem that the residues in the conduit 21 fall due to natural gravity and affect the working environment.

[0070] Furthermore, if Fig.11 and Fig.12As shown, an extension plate 50 is fixedly connected to one side of the scraper 49 at both ends close to the storage tank 15. The extension plate 50 improves the scraper 49's barrier and diversion effect on the residue, so that the scraped residue returns to the storage tank 15 more stably.

[0071] In this embodiment, there is also, Fig.12 As shown, in order to improve the extrusion effect of the pressure plate B39 on the plastic PP plastic in the storage tank 15, a deflector 51 adapted to the storage tank 51 can be installed inside the storage tank 15, a deflector 51 is provided at the top of the deflector 51, and a leakage hole 53 connected to the extrusion pipe 16 is provided at the bottom of the deflector 52.

[0072] The guide groove 52 facilitates the plastic PP plastic to gather toward the middle, and then cooperates with the pressing plate B39 to improve the stability of the plastic PP plastic when it is extruded downward.

[0073] In this embodiment, there is also, Fig.13 As shown, a conveying component 54 is provided below the outer shell 1 , and a plurality of mold supports 55 are provided on the conveying component 54 . A molding mold is installed on the top of the mold support 55 , and a cooling system is installed on the mold support 55 .

[0074] A plurality of mold supports 55 are carried by a conveying component 54. The molding molds on the top of the mold supports 55 can be set as product molds of different specifications or shapes. The plurality of molding molds are transported by the conveying component 54 so as to correspond to the extrusion tube 16 in sequence. Then, under the downward pressure drive of the lifting cylinder 43, the molding mold is filled with plastic PP plastic. Then, the molding mold is cooled and formed by the cooling system to shape the product.

[0075] See also Figure 1-13 As shown, the present application also discloses a processing method relying on the above-mentioned PP plastic particle processing equipment, which specifically comprises the following steps:

[0076] S1, material preparation and equipment power-on inspection. Before production, PP plastic particles are first prepared according to the required amount of production and processing shape;

[0077] S2, material addition, PP plastic particles are pre-stored in the Jiaolong conveyor 6 and the inside of the feed port 7 through the feed port 7 in the feed mechanism 3, and driven by the drive motor A5, the PP plastic particles are delivered to the inside of the cartridge heater 10 through the material conveying pipe 8 and the cartridge heater 10;

[0078] S3, heating and melting, the cartridge heater 10 is powered on, a temperature sensor is provided inside the cartridge heater 10, and while monitoring the temperature of the cartridge heater 10, the cartridge heater 10 heats the PP plastic particles inside within the melting temperature range to transform them into a plastic state;

[0079] S4, discharge extrusion, after the cylindrical heater 10 heats the PP plastic particles for a predetermined time and the PP plastic particles are in a plastic state, the two drive motors B41 drive the drive shaft 45 to rotate, during the rotation of the drive shaft 45, the internal thread slider 34 moves horizontally, and the extrusion assembly A11 is driven to move synchronously through the telescopic connecting component 12, during the movement of the extrusion plate 20, the melted PP plastic is extruded, and during the continuous inward movement of the extrusion plate 20, the plastic PP plastic falls downward through the conduit 21 into the storage tank 15 for collection;

[0080] S5, adding material to the mold. When the extrusion plate 20 completely extrude the PP plastic in the tubular heater 10, the multiple mold brackets 55 are carried and transported forward by the conveying component 54. The molding molds on the top of the multiple mold brackets 55 are transported forward in turn and correspond to the extrusion tube 16 under the transportation of the conveying component 54. When each molding mold corresponds to the extrusion tube 16, the telescopic cooperation of the movable cavity 24 and the telescopic column 25 can further extend the distance that the telescopic connecting component 12 continues to move backward, so that the internal thread slider 34 can drive the pressing plate A38 and the pressing plate B39 to move synchronously through the "L"-shaped extension connecting piece 37, corresponding to the position of the storage tank 15. At this time, the lifting cylinder 43 drives the driving motor B41 to fall through the fixed plate 44. During the falling process, the pressing plate B39 moves downward along the inner wall of the storage tank 15 and squeezes the PP plastic in a plastic state downward into each molding mold.

[0081] S6, cooling and demoulding, the cooling system on the mold support 55 cools and solidifies the PP plastic product in the molding mold. After the PP plastic product is completed and the temperature is stable, the molded PP plastic product is extruded by the demoulding tool equipment to complete the production of the PP plastic product.
