Description

Technical Field

[0001] The present invention relates to the technical field of SMC composite material processing, and more specifically, to a SMC composite material processing device and a production process thereof. Background Art

[0002] In the production and processing of SMC composite materials, high-speed stirring is the key process link to ensure that the raw materials are fully mixed. Traditional stirring equipment usually adopts a conventional stirring paddle structure. This design has obvious limitations in practical applications. Due to the effect of centrifugal force, the materials will be thrown to the edge of the container during the stirring process, so that the area close to the periphery of the stirring paddle obtains a better mixing effect. This phenomenon causes the stirring effect to show obvious radial differences. The materials in the edge area are fully mixed, while the stirring intensity in the center area is relatively insufficient.

[0003] However, in order to improve the stirring effect in the central area, if a stirring structure or filler is simply added at the central position, although the stirring intensity can be improved to a certain extent, the effective volume of the stirring container will be significantly reduced. This trade-off leads to a decrease in production efficiency because the amount of material that can be processed in each batch is reduced, and the filler at the central position may interfere with the natural flow of the material, thereby affecting the overall stirring uniformity.

[0009] The steering mechanism includes at least four rotating rods rotatably connected to the revolving frame, a reversing plate is installed at the lower end of each rotating rod, a rotating wheel is installed at the upper end of the rotating rod, an adjusting wheel is rotatably connected to the revolving frame, a plurality of rotating wheels are respectively meshed with the adjusting wheels, at least four annular grooves are evenly spaced in the adjusting wheel, each of the annular grooves is respectively installed with side springs of different diameters, an annular block is installed at the middle position of each side spring, and each annular block is respectively slidably connected in the annular groove.

[0011] Preferably, an inner sleeve is fixedly installed in each of the fixing holes, and a positioning rod is coaxially slidably installed in the inner sleeve. When the adjustment wheel is adjusted, the positioning rod is inserted into the corresponding positioning hole.

[0012] Preferably, a plurality of guide holes are formed at equal intervals on the outer wall of the inner sleeve, a guide rod is slidably connected in each guide hole, a fitting plate is installed between every two guide rods, a plurality of fitting blocks are installed on the side of the fitting plate close to the axis of the inner sleeve, a plurality of one-way rings are installed on the side wall of the positioning rod, and the fitting blocks abut against the one-way rings.

[0013] Preferably, a transverse plate is installed on the side of each bonding plate away from the bonding block, a plurality of transverse grooves are opened on the side wall of the inner sleeve, the transverse plate is slidably connected in the transverse grooves, and a spring is installed on the bonding plate, and the spring abuts against the inner wall of the inner sleeve.

[0014] Preferably, an expansion sleeve is slidably connected to the outer wall of the inner sleeve, and the expansion sleeve is provided with expansion grooves with the same number as the transverse plates. A follower ball is respectively installed on each of the transverse plates, and the follower ball is attached to the outer wall of the expansion sleeve. A stop groove is provided on the outer wall of the expansion sleeve, and when the attachment block is away from the one-way ring, the follower ball is stuck in the stop groove.

[0015] Preferably, a lifting block is coaxially installed on the upper end surface of the positioning rod, the lifting block is slidably connected in the fixing hole, and a handle is installed on the lifting block, and a plurality of pressure rods are evenly installed on the lower end surface of the lifting block, and the plurality of pressure rods are respectively abutted against the expansion sleeve, and a tension spring is slidably sleeved on each of the pressure rods, and the two sides of the tension spring are respectively connected to the expansion sleeve and the lifting block.

[0016] Preferably, the stirring mechanism also includes a follower wheel fixedly mounted on the plurality of self-rotating frames, an external wheel is fixedly mounted on the inner wall of the stirring box, the plurality of follower wheels are respectively meshed with the external wheel, and each of the self-rotating frames is respectively mounted with no less than four spiral blades.

[0018] The present invention provides a production process of an SMC composite material, comprising the following steps:

[0019] Step 1: The raw materials enter the mixing box through multiple feed pipes, and the external driving device starts to drive the revolving frame to start rotating. Due to the meshing action of the follower wheel and the external wheel, multiple self-rotating frames simultaneously generate self-rotation motion, and the spiral blades begin to perform preliminary stirring on the materials. At this time, the materials begin to generate radial flow and local turbulence;

[0020] Step 2: Driven by the revolution frame, the peripheral materials are strongly stirred by the spiral blades. At the same time, the commutator segments swing back and forth under the dual effects of the raw material impact force and the spring rebound force. Through the synchronous transmission of the adjusting wheel, multiple commutator segments work together to conduct multi-directional flow diversion and disturbance on the materials in the central area, achieving a full range of mixing effects. Side springs of different diameters provide adjustable rebound force, ensuring the optimization of the commutation effect.

[0021] Step three, according to the actual mixing needs, the operator can adjust the insertion position of the positioning rod through the handle, change the initial angle of the commutator segment, and optimize the mixing effect. When the material reaches the expected mixing degree, the mixed material is discharged through the discharge pipe. During the whole process, the fixing mechanism ensures the stability and reliability of the position of each component through the cooperation of components such as the fitting block and the one-way ring.

[0022] (III) Beneficial effects

[0023] Compared with the prior art, the present invention provides a processing device and a production process of SMC composite materials, which have the following beneficial effects:

[0024] The combined movement of the revolving frame and multiple self-rotating frames achieves a double stirring effect. The rotation of the revolving frame drives the overall material flow, while the spiral blades on the self-rotating frame generate strong shear force and turbulence in local areas. This design combining revolution and rotation not only improves the uniformity of stirring, but also significantly enhances the mixing effect. In particular, the meshing transmission design of the follower wheel and the external wheel ensures the stability and reliability of the self-rotating motion, effectively avoiding the dead angle problem common in traditional mixing equipment.

[0025] A unique flow-guiding and reversing system is formed by the cooperation of multiple rotating rods and commutator segments. The meshing transmission of the rotating wheel and the adjusting wheel ensures the synchronous movement of the commutator segments, while the side springs of different diameters installed in the annular groove provide adjustable rebound force. This design enables the material to not only flow radially during the mixing process, but also to achieve multi-directional disturbances, especially for the material in the central area. The sliding design of the annular block and the cooperation of the positioning system provide reliable guarantees for the angle adjustment of the commutator segments.

[0026] Through the coordinated work of components such as the internal sleeve, positioning rod, and bonding plate, a convenient adjustment function is achieved. In particular, the coordinated design of the guide rod, bonding block, and one-way ring ensures the stability and reliability of the positioning process. The design of the expansion sleeve and follow-up ball provides a quick unlocking function, while the coordination of the pressure rod and tension spring ensures the reset reliability of the entire mechanism. This multi-protection fixing mechanism not only improves the operating convenience of the equipment, but also ensures the stability of the position of each component during the mixing process.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0038] In the present invention, unless otherwise specified, the directions used, such as "up" and "down", usually refer to the directions shown in the drawings, or to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0039] See also Figures 1 to 4 A processing equipment for SMC composite materials includes a fixed frame 11 installed on an external device and a mixing box 12 fixedly installed on the fixed frame 11, a mixing mechanism includes a revolving frame 21 rotatably connected to the mixing box 12, the revolving frame 21 is connected to an external driving device, and no less than four self-rotating frames 22 are rotatably connected to the revolving frame 21, the mixing mechanism also includes a follower wheel 23 fixedly installed on the plurality of self-rotating frames 22, an external wheel 24 is fixedly installed on the inner wall of the mixing box 12, and the plurality of follower wheels 23 are respectively meshed with the external wheel 24, and no less than four spiral blades 25 are respectively installed on each self-rotating frame 22, a plurality of feed pipes 41 are connected and installed on the upper end of the mixing box 12, a discharge pipe 42 is installed on the lower end of the mixing box 12, and the plurality of feed pipes 41 and the discharge pipe 42 are respectively connected to the external device.

[0040] First, please refer to Figure 2When the raw materials of the SMC composite material are stirred, the corresponding raw materials are first introduced into the stirring box 12 through multiple feeding pipes 41, and then the rotation of the revolution frame 21 can be driven by an external driving device. Since the follower wheel 23 is engaged with the external wheel 24, and the external wheel 24 is fixedly installed in the stirring box 12, the multiple self-rotating frames 22 will also rotate with the rotation of the revolution frame 21, and then the various raw materials inside are stirred. Since the raw materials are driven to rotate under the action of the revolution frame 21, and the raw materials on the outside are also additionally rotated by the spiral blades 25, the stirring effect will be improved, but the middle part will not be stirred by the spiral blades 25, so it is necessary to change the angle of the raw materials through multiple commutator plates 32 to divert and reverse the flow, so that the raw materials can be disturbed in multiple directions inside, thereby increasing the stirring effect, and can be discharged through the discharge pipe 42 after the stirring is completed.

[0041] See also Figures 1 to 8The steering mechanism includes at least four rotating rods 31 rotatably connected to the revolving frame 21, a commutating plate 32 is installed at the lower end of each rotating rod 31, a rotating wheel 33 is installed at the upper end of the rotating rod 31, an adjusting wheel 34 is rotatably connected to the revolving frame 21, and multiple rotating wheels 33 are respectively engaged with the adjusting wheel 34, and at least four annular grooves 35 are evenly spaced in the adjusting wheel 34, each annular groove 35 is respectively installed with side springs 36 of different diameters, and an annular block 37 is installed in the middle position of each side spring 36, and each annular block 37 is respectively slidably connected in the annular groove 35. The steering mechanism also includes a fixing hole 38 opened on the annular block 37, and the revolving frame 21 is provided with a plurality of rotating wheels 33. A plurality of positioning holes 39 are formed at equal intervals on the upper end surface of the inner sleeve 310, and the distance between the plurality of positioning holes 39 and the axis is equal to the distance between the fixing hole 38 and the axis. An inner sleeve 310 is fixedly installed in each fixing hole 38, and a positioning rod 311 is slidably installed in the inner sleeve 310 coaxially. When the adjustment wheel 34 is adjusted, the positioning rod 311 is inserted into the corresponding positioning hole 39. A plurality of guide holes 312 are formed at equal intervals on the outer wall of the inner sleeve 310, and a guide rod 313 is slidably connected in each guide hole 312. A fitting plate 314 is installed between every two guide rods 313, and a plurality of fitting blocks 314 are installed on one side of the fitting plate 314 close to the axis of the inner sleeve 310. 15. A plurality of one-way rings 316 are installed on the side wall of the positioning rod 311, and the fitting block 315 abuts against the one-way ring 316. A transverse plate 317 is installed on the side of each fitting plate 314 away from the fitting block 315. A plurality of transverse grooves 318 are provided on the side wall of the inner sleeve 310, and the transverse plate 317 is slidably connected in the transverse grooves 318. A spring 319 is installed on the fitting plate 314, and the spring 319 abuts against the inner wall of the inner sleeve 310. An expansion sleeve 320 is slidably connected to the outer wall of the inner sleeve 310. The expansion sleeve 320 is provided with the same number of expansion grooves 321 as the transverse plate 317. A follower ball 322 is installed on each transverse plate 317. 322 fits on the outer wall of the expansion sleeve 320, and a stop groove 323 is provided on the outer wall of the expansion sleeve 320. When the fitting block 315 is away from the one-way ring 316, the follower ball 322 is stuck in the stop groove 323. A lifting block 324 is coaxially installed on the upper end surface of the positioning rod 311. The lifting block 324 is slidably connected in the fixing hole 38, and a handle 325 is installed on the lifting block 324. A plurality of pressure rods 326 are evenly installed on the lower end surface of the lifting block 324. The plurality of pressure rods 326 respectively abut against the expansion sleeve 320, and a tension spring 327 is slidably sleeved on each pressure rod 326. The two sides of the tension spring 327 are respectively connected to the expansion sleeve 320 and the lifting block 324.

[0042] Please refer to Figure 3 and Figure 4When the raw material rotates, the raw material in the middle position will also flow due to the viscosity of the raw material, and will be impacted in multiple directions along the positions of the multiple commutator segments 32, thereby ensuring the uniformity of the mixing. The side springs 36 of corresponding diameters are selected according to the conditions of the raw material, and then the positioning rods 311 at the corresponding positions are inserted into the positioning holes 39. At this time, only the annular block 37 at this position is in a positioned state, and the adjusting wheel 34 and the revolving frame 21 are in a rotating state, and the multiple rotating wheels 33 are engaged with the adjusting wheel 34, so that the multiple commutator segments 32 are impacted. When striking, the other commutator segments 32 will be synchronously driven to rotate, thereby improving the guiding effect. The corresponding side springs 36 can provide return force to ensure reciprocating vibration. When stirring, multiple commutator segments 32 will swing back and forth under the impact force of the raw materials and the rebound force of the springs 319, thereby increasing the internal chaos. The initial fixed angle of the commutator segment 32 can be changed by changing the positioning rod 311 and inserting it into different positioning holes 39, thereby avoiding insufficient stirring of the intermediate raw materials, thereby improving the stirring effect.

[0043] When the positioning rod 311 needs to be inserted into the positioning hole 39, refer to Figure 5 and Figure 6 First, the operator drives the handle 325 to move downward, and then the positioning rod 311 will be inserted downward, and the positioning rod 311 will push open the multiple fitting plates 314, and then make its guide rod 313 slide outward along the guide hole 312, so that the one-way ring 316 is inserted into the fitting block 315. When the one-way ring 316 passes over the fitting block 315, under the action of the spring 319, the fitting block 315 will abut against the side wall of the positioning rod 311, ensuring the one-way fixation of the positioning rod 311. At this time, the positioning rod 311 is inserted into the positioning hole 39, ensuring the fixation of the annular block 37. At this time, the lifting block 324 is not in contact with the inner sleeve 310, and the lower end surface of the expansion sleeve 320 just contacts the follower ball 322, and the pressure rod 326 abuts against the expansion sleeve 320.

[0044] When it is necessary to release the connection between the positioning rod 311 and the positioning hole 39, refer to Figure 6At this time, continue to press the handle 325, and then the pressure rod 326 will push the expansion sleeve 320 to slide downward. Since the follower ball 322 contacts the outer wall of the expansion sleeve 320, it will drive the fitting plate 314 to expand outward, and then release the connection between the fitting block 315 and the one-way ring 316, and then continue to push so that the follower ball 322 is stuck in the stop groove 323. At this time, stop pressing downward, and then pull the handle 325 upward. First, the one-way ring 316 on the positioning rod 311 passes over the closest fitting block 315. Since the tension spring 327 is connected to the expansion sleeve 320, as it continues to rise, the pulling force continues to increase, and the expansion sleeve 320 moves upward, releasing the clamping between the stop groove 323 and the follower ball 322, thereby completing the reset so that the fitting block 315 contacts the side wall of the positioning rod 311, and at this time the positioning rod 311 returns, releasing the connection with the positioning hole 39, thereby completing the unlocking process.

[0045] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which will not be described one by one here. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
