Description

Technical Field

[0001] The present invention relates to the technical field of PC resin preparation equipment, in particular to a modified PC resin raw material mixing box and a mixing method. Background Art

[0002] PC resin, also known as PC plastic, is a high-molecular-weight polymer containing carbonate groups in its molecular chain. Based on the structure of the ester groups, it can be categorized into aliphatic, aromatic, and aliphatic-aromatic types. Due to the structural peculiarities of polycarbonate, it has become the fastest-growing general-purpose engineering plastic among the five major engineering plastics. However, the relatively low mechanical properties of aliphatic and aliphatic-aromatic polycarbonates limit their application in engineering plastics. Consequently, modified PC resins have emerged, produced by adding modifying materials to PC raw materials. The preparation of modified PC resins begins with raw material mixing. Raw materials in different forms, such as liquid and solid, are weighed, mixed, and molded by stirring. Further processing then yields the modified PC resin.

[0003] Comparative document 1 (CN201921919043.4) discloses a stirring raw material mixing tank for the production of polyurethane resin for leather, comprising a mixing tank body, a servo motor and a discharge valve. A servo motor is installed above the mixing tank body, and a stirring shaft is installed below the servo motor.

[0004] The uniformity of mixing and dissolution of solid materials during the raw material preparation process is an important factor in determining the quality of modified PC resin. When stirring raw materials, some existing raw material preparation boxes, such as Comparative Document 1, add the raw materials into the preparation box all at once, and some insoluble raw materials cannot be fully dissolved in the mixture. In addition, the stirring rod in the existing raw material preparation box, such as Comparative Document 1, has a relatively simple movement mode and low mixing efficiency. Summary of the Invention

The invention solves the problems mentioned in the above background technology that, when stirring raw materials, some existing raw material mixing boxes add the raw materials into the mixing box all at once, some insoluble raw materials aggregate and cannot be fully dissolved in the mixture without sufficient reaction time, and the stirring rods in some existing raw material mixing boxes have a relatively single movement mode and low mixing efficiency.

[0016] As an optional solution of the modified PC resin raw material mixing box described in the present invention, the stirring mechanism further includes a rotating block arranged on the turntable, a rotating groove is opened on the box body, and the rotating block is rotatably arranged in the rotating groove.

[0017] As an optional solution of the modified PC resin raw material mixing box described in the present invention, the stirring mechanism also includes two limiting parts respectively arranged on the two discharge pipes, limiting grooves are provided in the two rotating rings, and the two limiting parts are respectively slidably arranged in the two limiting grooves.

[0018] As an optional solution of the modified PC resin raw material mixing box described in the present invention, the stirring mechanism further includes two second springs respectively arranged on the two discharge pipes, and the two second springs are respectively connected to the inner walls of the two rotating rings.

[0019] As an optional solution of the modified PC resin raw material mixing box described in the present invention, the box body is further provided with a filtering mechanism, and the filtering mechanism includes a filter plate slidably arranged in the discharge pipe.

[0020] As an optional solution of the modified PC resin raw material mixing box described in the present invention, the filtering mechanism also includes a connecting rod arranged on the filter plate, a connecting plate is provided on the connecting rod, and the two discharge pipes are both rotatably arranged on the connecting plate.

[0021] The present invention also provides the following technical solution: a method for preparing a modified PC resin raw material preparation box, comprising the following steps:

[0022] S1. First, liquid raw materials are injected into two discharge pipes. The liquid raw materials flow into the box through several discharge ports, and then the remaining raw materials are added into several storage chambers through several injection ports;

[0023] S2. Control the motor to operate, and drive the sun gear to rotate. The sun gear then drives the two planetary gears and the two discharge pipes to rotate around the box under the action of the ring gear, while rotating on their own. The raw materials in the box are stirred by the several stirring blades on the two discharge pipes, so that the raw materials are mixed and prepared;

[0024] S3. While the two discharge pipes rotate around the box, they are guided by two annular wave guide rails to simultaneously perform reciprocating lifting motions, thereby driving two push rods to sequentially push open several sealing plates, so that the raw materials in the several storage chambers are injected into the box in multiple times and mixed with other raw materials in the box through stirring;

[0025] S4. During the mixing process of the raw materials, some undissolved raw material particles fall on the filter plate. At this time, the two discharge pipes are driven by the connecting plate and the connecting rod, so that the filter plate also performs reciprocating lifting and lowering motion, pushing the precipitated raw material particles back into the box for re-mixing until the dissolution is complete;

[0026] S5. After the raw materials are prepared, stop the motor and open the valve on the discharge pipe to take out the raw materials.

[0027] The present invention has the following beneficial effects:

[0028] 1. The modified PC resin raw material mixing box and mixing method. In the existing raw material mixing process, the box body is usually equipped with only one feed port, and different raw materials are fed through the same feed port. This can easily lead to insufficient reaction when the reaction conditions are not met during the feeding process. In addition, some insoluble raw materials are not conducive to complete dissolution if they are added all at once.

[0029] In this device, one or more liquid raw materials can be injected into the box through two discharge pipes and flow out through several discharge ports on the two discharge pipes, while the remaining raw materials, including some raw materials that need to be added step by step, are stored in several storage cavities on the storage box and sealed by several sealing plates.

[0030] When the stirring mechanism is operating to stir the raw materials in the box, the two discharge pipes rotate around the box. At the same time, due to the setting of the annular wave guide rail, the two discharge pipes simultaneously make reciprocating lifting and lowering motions under the elastic force of the two second springs. During the reciprocating lifting and lowering, the two push rods installed on the two discharge pipes will push open several sealing plates in turn when they are raised, causing a part of the raw materials in several storage cavities to fall down, and then the several storage cavities are re-closed under the elastic force of several first springs.

[0031] This allows different raw materials to be injected and stored separately during the raw material preparation process, avoiding incomplete reactions, and allowing some insoluble raw materials to be injected multiple times to give them sufficient reaction time, thereby improving the efficiency of raw material preparation and the quality of modified PC resin.

[0032] 2. The modified PC resin raw material mixing box and mixing method, in the existing raw material mixing process, the stirring method is relatively simple, usually a single circular rotation, or a double planetary gear stirring, without vertical changes.

[0033] In this device, in addition to being used for discharging materials, the two discharge pipes also play a stirring role through a number of stirring blades installed thereon. Driven by the motor and driven by a double planetary gear structure consisting of a sun gear, a ring gear and two planetary gears, the two discharge pipes rotate around the box body while rotating on their own to stir.

[0034] And because of the driving of the annular wave guide rail, the two discharge pipes also perform reciprocating lifting motion at the same time, so that the stirring is more sufficient and the mixing is more uniform.

[0035] 3. The modified PC resin raw material mixing box and mixing method. Due to the raw material mixing process, it is inevitable that some particles are not completely reacted and dissolved and sink to the bottom. At this time, these particles that fall on the filter plate and sink to the bottom will be filtered and precipitated on the filter plate.

[0036] The filter plate also makes a reciprocating lifting motion driven by the two discharge pipes, so that when it rises, it pushes the settled particles back into the box for re-stirring. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] Example 1

[0045] In the preparation of modified PC resin, it is necessary to weigh the corresponding amounts of different types of raw materials for mixing and blending. The resin material is added as the main material in large amounts, while the modifying material is added as the auxiliary material in small amounts. Different modifying materials are added according to different design purposes. For example, polytetrafluoroethylene and whisker silicon need to react for a sufficient time under sufficient reaction conditions to fully dissolve and form a mixture. In addition, raw materials in different forms, such as liquid and solid, should also be stored and discharged separately to avoid insufficient reaction when the reaction conditions are not met. In order to solve the above problems, a modified PC resin raw material mixing box is proposed;

[0046] See also Figure 1-Figure 5 , comprising a box body 1 and a discharge pipe 101 provided on the box body 1, a valve being provided on the discharge pipe 101, and a first discharge mechanism 2 and a second discharge mechanism 3 being provided on the box body 1;

[0047] The first discharge mechanism 2 includes two discharge pipes 201 symmetrically arranged in the box body 1 for injecting liquid raw materials. Both discharge pipes 201 are provided with a plurality of discharge ports 202.

[0048] The second discharge mechanism 3 includes a storage box 301 provided on the box body 1. The storage box 301 is provided with a plurality of storage chambers 302 for storing the remaining types of raw materials. The plurality of storage chambers 302 are each hinged with a sealing plate 304 via a hinge shaft. A push rod 306 is provided on each of the two discharge pipes 201.

[0049] The box body 1 is also provided with a stirring mechanism 4 for stirring and mixing the raw materials. The stirring mechanism 4 includes a plurality of stirring blades 401 respectively provided on the two discharge pipes 201. The stirring mechanism 4 stirs the raw materials by driving the two discharge pipes 201 to rotate in the box body 1.

[0050] The stirring mechanism 4 further includes an annular wave guide rail 410 disposed in the housing 1 , and the two discharge pipes 201 are both slidably disposed on the annular wave guide rail 410 , so that the two discharge pipes 201 perform reciprocating lifting motion while rotating;

[0051] The second discharge mechanism 3 further includes a plurality of first springs 305 respectively provided on the plurality of sealing plates 304, and the plurality of first springs 305 are respectively connected to the inner walls of the plurality of storage chambers 302;

[0052] The material storage box 301 is provided with a plurality of material injection ports 303 , and the plurality of material injection ports 303 are respectively communicated with the plurality of material storage chambers 302 .

[0053] In this embodiment, the discharge pipe 101 is installed at the lower end of the box body 1, and a valve is installed on the discharge pipe 101. The valve can be a manual valve or a solenoid valve. Before the raw material preparation is completed, the valve is in a closed state.

[0054] The two discharge pipes 201 are located in the box body 1 and are symmetrical based on the midpoint of the box body 1. A number of discharge ports 202 are opened on the two discharge pipes 201. Liquid raw materials can be injected through the upper openings of the two discharge pipes 201. This process can be carried out before stirring or while stirring.

[0055] If the latter, it is necessary to set the metering pump and other equipment for injecting liquid raw materials to be rotatably mounted with the discharge pipe 201. The liquid raw materials eventually enter the box body 1 through a plurality of discharge ports 202. The purpose of setting a plurality of discharge ports 202 is to accelerate the outflow of the raw materials.

[0056] The storage box 301 is installed on the box body 1, and is provided with several storage cavities 302 and several injection ports 303 inside. Different solid or liquid raw materials, including some raw materials that need to be added in multiple times for slow reaction, can be placed in the several storage cavities 302 through the several injection ports 303 and stored separately.

[0057] The plurality of sealing plates 304 are respectively used to seal the plurality of storage chambers 302. One end of the plurality of first springs 305 is respectively fixed on the plurality of sealing plates 304, and the other end is respectively fixed on the inner wall of the plurality of storage chambers 302. A push rod 306 is installed on both discharge pipes 201.

[0058] The discharge pipe 201 itself plays a stirring role. A number of stirring blades 401 are installed on the two discharge pipes 201. During the process of the two discharge pipes 201 being driven by the stirring mechanism 4 to rotate around the box 1 for stirring, the guiding effect of the annular wave guide rail 410 will make the two discharge pipes 201 not only simply rotate and stir, but also be accompanied by reciprocating lifting motion.

[0059] This improves the stirring effect while also driving the two push rods 306 to perform a reciprocating lifting motion. As they rise, they press against the sealing plates 304 in sequence, pushing them open. This causes a portion of the raw materials in the storage chambers 302 to fall out. When the two push rods 306 descend, the sealing plates 304 are resealed under the elastic force of the first springs 305. This allows for a gradual and gradual release of some of the raw materials, allowing them ample time to react.

[0060] In order to prevent the first springs 305 from vibrating continuously during rebound and causing unstable closure, a shock absorber may be provided accordingly. While the heating device that may be required for raw material preparation is not shown on the housing 1, a heating device may be provided on the housing 1 to meet heating regulation.

[0061] Example 2

[0062] In order to drive the two discharge pipes 201 to rotate for stirring, and to prevent the reciprocating and lifting motion from being affected during the rotation, embodiment 2 is proposed.

[0063] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 5 The stirring mechanism 4 further includes a turntable 402 rotatably disposed in the box body 1 , and two rotating rings 403 are rotatably disposed on the turntable 402 , and the two rotating rings 403 are respectively connected to the two discharge pipes 201 ;

[0064] The stirring mechanism 4 further includes a motor 404 disposed on the box body 1 , and a sun gear 405 is disposed on the output shaft of the motor 404 ;

[0065] The two discharge pipes 201 are both provided with planetary gears 406, and the two planetary gears 406 are meshed with the sun gear 405. The housing 1 is provided with a ring gear 407, and the ring gear 407 is meshed with the two planetary gears 406.

[0066] The stirring mechanism 4 further includes a rotating block 408 disposed on the rotating disk 402. A rotating groove 409 is provided on the housing 1, and the rotating block 408 is rotatably disposed in the rotating groove 409.

[0067] The stirring mechanism 4 further includes two limiting portions 411 respectively provided on the two discharge pipes 201 . A limiting groove 412 is provided in each of the two rotating rings 403 , and the two limiting portions 411 are respectively slidably provided in the two limiting grooves 412 .

[0068] The stirring mechanism 4 further includes two second springs 413 respectively provided on the two discharge pipes 201 , and the two second springs 413 are respectively connected to the inner walls of the two rotating rings 403 .

[0069] In this embodiment, a turntable 402 is rotatably mounted on the inner wall of the box body 1 , and a turn block 408 is mounted on the turntable 402 . The turntable 402 can be rotated more stably by the turn block 408 rotating along a rotation groove 409 provided on the inner wall of the box body 1 .

[0070] Two rotating rings 403 are rotatably mounted on the turntable 402. A polygonal limiting groove 412 is provided inside the two rotating rings 403. A second polygonal spring 413 is provided in the middle of the two discharge pipes 201 for transmission.

[0071] The two discharge pipes 201 pass through the two rotating rings 403 and are connected by sliding along the limiting grooves 412 via the limiting portions 411. One end of the two second springs 413 is fixed to the surface of the two discharge pipes 201, and the other end of the two second springs 413 is fixed to the inner walls of the two rotating rings 403. The elastic force of the two second springs 413 presses the two discharge pipes 201 downward.

[0072] A motor 404 is mounted on the housing 1 , with the output shaft of the motor 404 pointing downwardly toward the midpoint of the housing 1 . A sun gear 405 is mounted on the output shaft of the motor 404 . Two planetary gears 406 are mounted on two rotating rings 403 , respectively. A gear ring 407 is also mounted on the inner wall of the housing 1 .

[0073] When the motor 404 is running, the sun gear 405 drives the two planetary gears 406 to roll, thereby driving the two discharge pipes 201 to revolve around the box body 1 while rotating. At the same time, through the guiding effect of the annular wave guide rail 410, the two discharge pipes 201 make reciprocating lifting movements. At this time, the two limiting parts 411 slide along the two limiting grooves 412 respectively.

[0074] Example 3

[0075] Since some incompletely dissolved particles may sink to the bottom during the stirring, mixing and dissolving process, Example 3 is proposed.

[0076] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 3 , the box body 1 is further provided with a filtering mechanism 5, and the filtering mechanism 5 includes a filter plate 501 slidably arranged in the discharge pipe 101;

[0077] The filter mechanism 5 further includes a connecting rod 502 disposed on the filter plate 501 . A connecting plate 503 is disposed on the connecting rod 502 . Both discharge pipes 201 are rotatably disposed on the connecting plate 503 .

[0078] In this embodiment, the filter plate 501 can rotate or slide along the inner wall of the discharge pipe 101. A connecting rod 502 is installed on the filter plate 501, and a connecting plate 503 is installed on the connecting rod 502. Both discharge pipes 201 are rotatably mounted on the connecting plate 503.

[0079] When the two discharge pipes 201 make reciprocating lifting motion, the filter plate 501 is also driven to move up and down, and when it is lifted up, the particles settled on the bottom are pushed into the box body 1 for re-stirring and mixing.

[0080] Therefore, the lower inner wall of the box body 1 is also configured to be inclined toward the discharge pipe 101 .

[0081] Example 4

[0082] In order to improve the efficiency of raw material mixing and realize automatic discharging and stirring, a mixing method for modified PC resin raw material mixing box is proposed;

[0083] For details, please refer to Figure 1-Figure 5 , including the following steps:

[0084] S1. First, liquid raw materials are injected into the two discharge pipes 201. The liquid raw materials flow into the box body 1 through the plurality of discharge ports 202. Then, the remaining raw materials are added into the plurality of storage chambers 302 through the plurality of injection ports 303.

[0085] S2. Control the motor 404 to operate, and the motor 404 drives the sun gear 405 to rotate. The sun gear 405 then drives the two planetary gears 406 and the two discharge pipes 201 to rotate around the box 1 while rotating on their own under the action of the ring gear 407. The stirring blades 401 on the two discharge pipes 201 stir the raw materials in the box 1, so that the raw materials are mixed and prepared;

[0086] S3. While the two discharge pipes 201 are rotating around the box body 1, the two annular wave guide rails 410 guide the two discharge pipes 201 to simultaneously perform reciprocating lifting motions, thereby driving the two push rods 306 to sequentially push open the sealing plates 304, so that the raw materials in the storage chambers 302 are injected into the box body 1 in multiple times and mixed with other raw materials in the box body 1 through stirring;

[0087] S4. During the mixing process of the raw materials, some undissolved raw material particles fall onto the filter plate 501. At this time, the two discharge pipes 201, through the transmission of the connecting plate 503 and the connecting rod 502, make the filter plate 501 also do reciprocating lifting and lowering motion, pushing the precipitated raw material particles back into the box 1 for re-mixing until the dissolution is complete;

[0088] S5. After the raw materials are prepared, the motor 404 is stopped, and the valve on the discharge pipe 101 is opened to take out the raw materials.

[0089] In this embodiment, by controlling the operation of the motor 404, the materials can be discharged and stirred at the same time.

[0090] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0091] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
