Description

Technical Field

[0001] This invention relates to the field of plastic processing technology, specifically to a UV-resistant PPE plastic processing equipment and process. Background Technology

[0002] PPE plastic, or polyphenylene oxide alloy, is one of the five major engineering plastics and the most consumed type of plastic alloy. PPE plastic possesses excellent physical and mechanical properties, heat resistance, and electrical insulation. It has low moisture absorption, high strength, and good dimensional stability, making it widely used in the manufacture of automotive dashboards and electrical components. Depending on its industrial application, some PPE plastics undergo modification treatment to enhance their UV resistance, resulting in PPE plastic products with stronger resistance to solar radiation and aging.

[0003] The processing technology of UV-resistant PPE plastic first involves granulating PPE plastic granules, then fully mixing the plastic granules with a UV absorber to form an injection molding raw material, which is then fed into an injection molding machine to form a mold and complete the processing.

[0004] Existing UV-resistant PPE plastic processing technology mixes plastic granules with UV absorbers simply by adding or stirring, resulting in uneven mixing. This means that the UV absorbers cannot be fully and evenly adhered to the surface of many plastic granules, leading to poor uniformity of injection molding raw materials and a decline in the quality of UV-resistant PPE plastic products.

[0005] For example, prior art document (CN201610713610.5) discloses an anti-UV automotive plastic part and its manufacturing process, which is produced through the following steps: ...stirring evenly to form a granulated powder ...granulating the granulated powder ...wetting the plastic granules and adding 0.2%-0.4% by mass of UV absorber UV-531 to form an injection molding raw material. In the prior art document, only the absorber is added to mix the two materials.

[0006] Therefore, to solve the above problems, a UV-resistant PPE plastic processing equipment and processing technology are proposed. Summary of the Invention

[0007] This invention provides a UV-resistant PPE plastic processing equipment and process, which features the beneficial effect of first coating PPE plastic granules with an adhesive, and then vibrating and sprinkling UV absorber powder onto the plastic granules during tumbling. This allows the powder to be fully and evenly adhered to the surface of the plastic granules, resulting in high-quality UV-resistant PPE plastic products. This solves the problem mentioned in the background art that existing UV-resistant PPE plastic processing processes, when mixing plastic granules and UV absorbers, only rely on simple addition or stirring, resulting in insufficient and uneven mixing. Consequently, a large number of plastic granules cannot be fully and evenly adhered to the surface of the UV absorber, leading to poor uniformity of injection molding raw materials and a decline in the quality of UV-resistant PPE plastic products.

The support mechanism is lifted by the lifting mechanism so that the plurality of first filter holes connect with the plurality of third filter holes, thereby causing the ultraviolet absorber powder to adhere to the plastic particles.

[0013] A lead screw is rotatably mounted on the base, and one of the sliders is threadedly connected to the lead screw. A first motor is mounted on the base, and the output shaft of the first motor is coaxially connected to the lead screw.

[0014] As an optional solution of the UV-resistant PPE plastic processing equipment of the present invention, the base is further provided with a material spreading mechanism for driving the storage frame to shake, and the material spreading mechanism includes a first guide rod provided on the storage frame;

[0015] The base is provided with a first guide rail, and the first guide rod is slidably disposed within the first guide rail. The material spreading mechanism drives the first guide rod to slide along the first guide rail, thereby causing the storage frame to shake.

[0016] As an optional solution of the UV-resistant PPE plastic processing equipment of the present invention, the material spreading mechanism further includes a second motor disposed on the base, a first rotating rod disposed on the output shaft of the second motor, a connecting rod disposed on the first rotating rod, a guide groove being formed on the connecting rod, and the first guide rod being slidably disposed in the guide groove.

[0017] As an optional solution of the UV-resistant PPE plastic processing equipment of the present invention, the bearing mechanism further includes a rotating body rotatably disposed on the housing and a valve disposed on the housing;

[0018] The shell is equipped with a tumbling mechanism to drive the plastic particles inside the shell to roll.

[0019] As an optional solution of the UV-resistant PPE plastic processing equipment of the present invention, the tumbling mechanism includes a plurality of vibration components disposed on the rotating body and a second guide rail disposed on the housing;

[0020] The vibration assembly includes a mounting groove formed on the rotating body, a vibration plate slidably disposed in the mounting groove, a second guide rod disposed on the vibration plate, and the second guide rod slidably disposed on the second guide rail.

[0021] As an optional solution of the UV-resistant PPE plastic processing equipment of the present invention, the vibration component further includes a rotating groove formed on the rotating body, and the rotating groove is connected to the mounting groove;

[0022] The vibrating plate is provided with a second rotating rod, which is rotatably disposed in the rotating groove. A torsion spring is provided on the second rotating rod, and the torsion spring is connected to the inner wall of the rotating groove.

[0023] As an optional solution of the UV-resistant PPE plastic processing equipment of the present invention, the vibration assembly further includes two elastic folding plates symmetrically arranged on the vibration plate, and the two elastic folding plates are respectively connected to the inner walls of the two sides of the mounting groove.

[0024] As an optional solution of the UV-resistant PPE plastic processing equipment of the present invention, the tumbling mechanism further includes a connecting groove formed on the rotating body, and the connecting groove is engaged with the first rotating rod.

[0025] This invention also provides the following technical solution: a processing technology for UV-resistant PPE plastic processing equipment, comprising the following steps:

[0026] S1. After injecting PPE plastic granules into the shell by opening the valve, the valve is closed. The first motor drives the shell to sink into the slurry tank. The heater is started to heat the adhesive in the slurry tank to reduce its stickiness, so that the surface of the plastic granules is wetted and coated with the adhesive.

[0027] S2. The first motor reverses to lift the housing, aligning several first filter holes with several second filter holes. The second motor drives the storage frame to sway along the trajectory of the first guide rail, intermittently connecting several third filter holes with several second filter holes, thus feeding material into the housing.

[0028] S3. Simultaneously with step S2, the rotating body rotates under the drive of the second motor, and several vibrating plates vibrate continuously, causing the plastic particles to tumble, so that the ultraviolet absorber powder is evenly adhered to the surface of the plastic particles, generating injection molding raw materials.

[0029] The present invention has the following beneficial effects:

[0030] 1. Compared to existing processes where PPE plastic granules and UV absorber powder are simply mixed by addition and stirring, this UV-resistant PPE plastic processing equipment and process first involves sinking a shell carrying PPE plastic granules into a slurry tank to wet and adhere the granules to an adhesive layer. Then, the shell is raised and aligned with a storage frame containing UV absorber powder for dispensing. The adsorption layer ensures that the UV absorber powder adheres fully and evenly to the surface of the plastic granules, resulting in a uniform injection molding raw material and thus improving the quality of the injection-molded PPE plastic products.

[0031] 2. The UV-resistant PPE plastic processing equipment and process includes a heater installed in the slurry tank to heat the adhesive, thereby reducing its viscosity and allowing it to flow better and coat the surface of the plastic particles, facilitating the formation of a uniform adsorption layer.

[0032] 3. In this UV-resistant PPE plastic processing equipment and process, when the UV absorber powder is added, the storage frame moves eccentrically along the trajectory of the horizontally distributed annular wave track (the first guide rail). This allows several third filter holes on the storage frame to intermittently connect with several first filter holes on the shell, controlling the powder's sprinkling speed and ensuring a slow, uniform sprinkle, which is beneficial for mixing. Furthermore, the reciprocating motion of the storage frame itself vibrates the internal powder, further promoting uniform distribution.

[0033] 4. In this UV-resistant PPE plastic processing equipment and process, when the shell is raised and docked with the storage mechanism, the first rotating rod used to drive the storage frame to make eccentric movement will be inserted into the rotating body that serves as the base of the shell, eliminating the need for an additional drive to rotate the rotating body. The rotation of the rotating body causes the plastic granules to tumble around the shell, allowing the plastic granules to fully contact the powder.

[0034] 5. In addition to the rotating body causing the plastic particles to tumble horizontally, the UV-resistant PPE plastic processing equipment and process also have several vibrating plates installed on the rotating body. As the body rotates, the plates will tumble up and down along the trajectory of the vertically distributed annular wave track, i.e., the second guide rail, to agitate the plastic particles and facilitate their tumbling, so that all the plastic particles can come into contact with the powder.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Example 1

[0045] In the processing of UV-resistant PPE plastics, in order to improve product quality, when mixing PPE plastic granules and UV absorbers, it is necessary to ensure that the two are fully mixed to form injection molding raw materials with uniform quality. Therefore, a UV-resistant PPE plastic processing equipment is proposed.

[0046] Please see Figures 1-7 It includes a base 1, on which a bearing mechanism 2 is provided. The bearing mechanism 2 includes a housing 201 for bearing PPE plastic particles. The housing 201 is connected to the base 1 through a lifting mechanism 3. A plurality of first filter holes 202 are provided on the housing 201.

[0047] The base 1 is provided with a slurry tank 4 for holding the adhesive, and a heater 401 is provided on the slurry tank 4. The lifting mechanism 3 drives the bearing mechanism 2 to sink into the slurry tank 4 to wet and coat the plastic particles with slurry.

[0048] A storage mechanism 5 is provided on the base 1. The storage mechanism 5 includes a support frame 501 provided on the base 1. A plurality of second filter holes 502 are provided on the support frame 501, and the plurality of second filter holes 502 respectively fit with a plurality of first filter holes 202.

[0049] A storage frame 503 for holding ultraviolet absorber powder is slidably disposed on the support frame 501. The storage frame 503 has a number of third filter holes 504, and the number of third filter holes 504 respectively fits with a number of second filter holes 502. The support mechanism 2 is lifted by the lifting mechanism 3 so that the number of first filter holes 202 are connected with the number of third filter holes 504, thereby causing the ultraviolet absorber powder to adhere to the plastic particles.

[0050] In this embodiment: the shell 201 is cylindrical and has a hollow structure inside, which is used to hold the PPE plastic granules produced by granulation. A plurality of first filter holes 202 are evenly distributed at the upper end of the shell 201. The diameter of the plurality of first filter holes 202 can be smaller than the diameter of the plastic granules to prevent the plastic granules from leaking out during subsequent processing.

[0051] On the lower side of the housing 201, a slurry tank 4 is installed on the base 1. The slurry tank 4 contains adhesive. The housing 201 is driven to sink into the slurry tank 4 by the lifting mechanism 3. The adhesive can enter the housing 201 through several first filter holes 202, so that the surface of the plastic particles is wetted and coated with adhesive to form an adsorption layer, which can better adhere to the ultraviolet absorber powder.

[0052] On the upper side of the housing 201, a support frame 501 is fixed on the base 1. The support frame 501 is circular with an open top. A storage frame 503 is slidably installed on the inner wall of the support frame 501. Several second filter holes 502 are opened at the lower end of the support frame 501, and several third filter holes 504 are also opened at the lower end of the storage frame 503. The storage frame 503 contains ultraviolet absorber powder. The housing 201 is raised by the lifting mechanism 3, so that several first filter holes 202 align with several second filter holes 502. The ultraviolet absorber powder will then pass through several third filter holes 504, several second filter holes 502, and several first filter holes 202 before being sprinkled into the housing 201 and adhering to the surface of the plastic granules.

[0053] It should be noted that paraffin wax can be chosen as a binder. Its advantages include a low melting point, thermoplasticity, and reduced viscosity after heating by the heater 401 installed on the slurry tank 4, allowing for better wetting of the plastic granule surface. Furthermore, paraffin wax is volatile during subsequent processing of the injection molding raw materials, thus not affecting the product composition.

[0054] Additionally, UV-531 can be selected as an ultraviolet absorber; it is a pale yellow needle-like crystalline powder. It features light color, non-toxicity, good compatibility, low migration, and ease of processing. It provides maximum protection for polymers, helps reduce color, and simultaneously delays yellowing and inhibits the loss of physical properties.

[0055] Example 2

[0056] To facilitate the lifting and lowering of the shell 201 for slurry application and material spreading, Example 2 is proposed.

[0057] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figures 1-2 The lifting mechanism 3 includes sliders 301 symmetrically arranged on the housing 201, and two slide grooves 302 symmetrically opened on the base 1, and the two sliders 301 are respectively slidably arranged in the two slide grooves 302.

[0058] A lead screw 303 is rotatably mounted on the base 1, and one of the sliders 301 is threadedly connected to the lead screw 303. A first motor 304 is mounted on the base 1, and the output shaft of the first motor 304 is coaxially connected to the lead screw 303.

[0059] In this embodiment: two sliders 301 are symmetrically fixed on both sides of the bearing mechanism 2, and vertically distributed linear grooves 302 are symmetrically opened on both sides of the base 1. The two sliders 301 are slidably installed in the two grooves 302 respectively. A first motor 304 is fixed on the upper inner wall of the groove 302 located on one side, and a lead screw 303 is fixed on the output shaft of the first motor 304. The lower end of the lead screw 303 is rotatably installed on the lower inner wall of the groove 302.

[0060] The slider 301 located on one side is threadedly connected to the lead screw 303, for example, a hole can be drilled in it to fix the lead screw nut. The first motor 304 drives the lead screw 303 to rotate, thereby driving the housing 201 to rise and fall.

[0061] Example 3

[0062] If the ultraviolet absorber powder in the storage box 503 is directly injected into the shell 201 in one go, the plastic particles in the shell 201 will not have enough time to come into contact with the powder and mix evenly. In order to solve this problem and realize the control of the connection between several third filter holes 504 and several second filter holes 502 to control the opening and closing of the material dispensing, Example 3 is proposed.

[0063] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figures 1-6 The base 1 is also provided with a material spreading mechanism 6 for driving the storage frame 503 to shake. The material spreading mechanism 6 includes a first guide rod 601 set on the storage frame 503.

[0064] A first guide rail 602 is provided on the base 1, and a first guide rod 601 is slidably disposed in the first guide rail 602. The first guide rod 601 is driven to slide along the first guide rail 602 by the material spreading mechanism 6, thereby causing the storage frame 503 to shake.

[0065] The material spreading mechanism 6 also includes a second motor 603 mounted on the base 1. A first rotating rod 604 is mounted on the output shaft of the second motor 603. A connecting rod 605 is mounted on the first rotating rod 604. A guide groove 606 is provided on the connecting rod 605. A first guide rod 601 is slidably mounted in the guide groove 606.

[0066] In this embodiment, the storage frame 503 is smaller than the support frame 501 and can slide at multiple angles up, down, left, and right along the inner wall of the support frame 501. Only when the storage frame 503 and the support frame 501 are coaxial can the plurality of third filter holes 504 and the plurality of second filter holes 502 be connected.

[0067] A first guide rod 601 is fixed at the upper end of the storage frame 503, and a first guide rail 602 is fixed on the upper inner wall of the base 1. The first guide rail 602 is a horizontal annular wave guide rail. The first guide rod 601 slides along the first guide rail 602, which can realize the eccentric sliding of the storage frame 503 on the support frame 501, so that a number of third filter holes 504 and a number of second filter holes 502 are intermittently connected, and the switching of material spreading is also realized.

[0068] A second motor 603 is fixed on the inner wall of the base 1. A first rotating rod 604 is fixed on the output shaft of the second motor 603. The first rotating rod 604 is rectangular and a connecting rod 605 is fixed on its surface. A straight guide groove 606 is opened on the connecting rod 605. The first guide rod 601 slides straight along the guide groove 606.

[0069] The operation of the second motor 603 can drive the first rotating rod 604 and the connecting rod 605 to rotate, thereby causing the first guide rod 601 to slide along the trajectory of the first guide rail 602.

[0070] At the same time, the eccentric sliding of the storage frame 503 also has the effect of reciprocating vibration of the internal powder, similar to a vibrating screen, which is conducive to the uniform distribution of powder.

[0071] Example 4

[0072] If the plastic particles inside the shell 201 are stationary during the spreading process, it is also not conducive to the adhesion of the powder. The plastic particles located on the lower side, as well as the lower and side surfaces of the plastic particles, cannot adhere well to the powder. Therefore, Example 4 is proposed.

[0073] This embodiment is an improvement upon embodiment 3. For details, please refer to [link / reference]. Figures 1-7 The bearing mechanism 2 also includes a rotating body 203 rotatably mounted on the housing 201 and a valve 204 mounted on the housing 201;

[0074] A tumbling mechanism 7 is provided on the housing 201 to drive the plastic particles inside the housing 201 to roll.

[0075] The tumbling mechanism 7 includes several vibration components 701 disposed on the rotating body 203 and a second guide rail 702 disposed on the housing 201;

[0076] The vibration assembly 701 includes a mounting groove 7011 opened on the rotating body 203, a vibration plate 7012 slidably disposed in the mounting groove 7011, a second guide rod 7013 disposed on the vibration plate 7012, and the second guide rod 7013 slidably disposed on the second guide rail 702.

[0077] The tumbling mechanism 7 also includes a connecting groove 703 formed on the rotating body 203, and the connecting groove 703 is engaged with the first rotating rod 604.

[0078] In this embodiment, a valve 204 is installed on the housing 201 as a switch. The valve 204 can be a manual valve, a solenoid valve, etc. By opening the valve 204, plastic granules can be injected into the housing 201. After the plastic granules and ultraviolet absorber powder are mixed, the plastic granules can be removed by opening the valve 204.

[0079] A rotating body 203 is rotatably mounted on the lower end of the housing 201. The rotating body 203 serves as the chassis of the housing 201, supporting the plastic particles and maintaining a good seal with the housing 201. A rectangular connecting groove 703 is provided on the upper end of the rotating body 203. When the lifting mechanism 3 drives the bearing mechanism 2 to rise, the first rotating rod 604 is inserted into the connecting groove 703, which can drive the rotating body 203 to rotate.

[0080] The rotating body 203 rotates, causing the internal plastic particles to rotate and tumble, mixing with the ultraviolet absorber powder. Furthermore, several vibrating plates 7012 are installed on the rotating body 203, which continuously rotate and tap the plastic particles as the rotating body 203 rotates, helping them to tumble and mix more evenly.

[0081] A second guide rod 7013 is fixed to the lower end of the vibrating plate 7012, and a second guide rail 702 is fixed to the lower end of the housing 201. The second guide rail 702 is a vertical annular wave track. The second guide rod 7013 slides along the second guide rail 702, which will rise and fall, causing the vibrating plate 7012 to beat the plastic particles.

[0082] It should be noted that some holes smaller than the diameter of the plastic particles can be opened at the lower end of the rotating body 203 to allow excess adhesive to flow out during the application of slurry.

[0083] Example 5

[0084] To increase the beating frequency of the vibrating plate 7012 and better drive the plastic particles to tumble during the rotation around the housing 201, Embodiment 5 is proposed;

[0085] This embodiment is an improvement upon embodiment 4. For details, please refer to [link / reference]. Figures 2-7 The vibration assembly 701 also includes a rotating groove 7014 formed on the rotating body 203, and the rotating groove 7014 is connected to the mounting groove 7011;

[0086] A second rotating rod 7015 is provided on the vibrating plate 7012, and the second rotating rod 7015 is rotatably disposed in the rotating groove 7014. A torsion spring 7016 is provided on the second rotating rod 7015, and the torsion spring 7016 is connected to the inner wall of the rotating groove 7014.

[0087] The vibration assembly 701 also includes two elastic folding plates 7017 symmetrically arranged on the vibration plate 7012, and the two elastic folding plates 7017 are respectively connected to the inner walls of the two sides of the mounting groove 7011.

[0088] In this embodiment: a rectangular mounting groove 7011 extending vertically through the rotating body 203 is provided, and several mounting grooves 7011 are distributed along several radii of the rotating body 203. A rotating groove 7014 is provided within the mounting groove 7011, and a second rotating rod 7015 is fixed to the middle of the vibrating plate 7012. The second rotating rod 7015 is rotatably mounted within the rotating groove 7014.

[0089] The two ends of the torsion spring 7016 are fixed to the surface of the second rotating rod 7015 and the inner wall of the rotating groove 7014, respectively. When the second guide rod 7013 slides along the trajectory of the second guide rail 702, it drives the vibration plate 7012 to rotate to one side based on the second rotating rod 7015, and then rotates to the other side under the rebound force of the torsion spring 7016, thereby increasing the vibration frequency.

[0090] The flexible folding plate 7017 is used to maintain the seal between 7012 and 7011 when 7012 rotates. The flexible folding plate 7017 can be made of a material and structure similar to a bellows.

[0091] Example 6

[0092] This invention also provides a processing technology for UV-resistant PPE plastic processing equipment;

[0093] For details, please refer to Figures 1-7 It includes the following steps:

[0094] S1. After injecting PPE plastic granules into the housing 201 by opening valve 204, valve 204 is closed. The first motor 304 drives the housing 201 to sink into the slurry tank 4. The heater 401 is started to heat the adhesive in the slurry tank 4 to reduce its stickiness, so that the surface of the plastic granules is wetted and coated with the adhesive.

[0095] S2. The first motor 304 rotates in reverse to lift the housing 201, so that a number of first filter holes 202 are aligned with a number of second filter holes 502. The second motor 603 rotates to drive the storage frame 503 to sway along the trajectory of the first guide rail 602, so that a number of third filter holes 504 and a number of second filter holes 502 are intermittently connected, and material is sprinkled into the housing 201.

[0096] S3. Simultaneously with step S2, the rotating body 203 rotates under the drive of the second motor 603, and several vibrating plates 7012 vibrate continuously, causing the plastic particles to tumble, so that the ultraviolet absorber powder is evenly adhered to the surface of the plastic particles, generating injection molding raw materials.
