[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0038] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0039] Example 1
[0040] Reference Figure 1 to Figure 17 , which is the first embodiment of the present invention, and the embodiment provides a modified plastic particle mixing device, which includes an adjusting component 200 and a main body component 100. Through the cooperation of the two, the modifier powder falling on the inner bottom wall of the mixer shell 101 can be blown to the plastic particles, so that the modifier powder and the plastic particles are fully mixed. At the same time, the air pressure of the jet can be automatically adjusted according to the amount of plastic particles in the mixer shell 101. When the amount of plastic particles in the mixer shell 101 is large, the air pressure of the jet is high, which can make the modifier powder and the plastic particles fully contact. When the amount of plastic particles in the mixer shell 101 decreases, the air pressure of the jet is reduced to prevent the "dust" phenomenon caused by blowing up the modifier powder due to the large jet pressure. When the amount of plastic particles in the mixer shell 101 is less than the threshold, the jet is no longer sprayed into the mixer shell 101, which can reduce the operating time of the jet device, thereby reducing its wear degree, extending its service life, and effectively avoiding the generation of the "dust" phenomenon.
[0041] Specifically, the main assembly 100 includes a mixer housing 101 , a stirring shaft 102 and a stirring paddle 103 . The stirring shaft 102 is rotatably connected to the mixer housing 101 , and the stirring paddle 103 is fixed to the surface of the stirring shaft 102 .
[0042] The mixer shell 101 is the shell of the modified plastic particle mixing device, which is used to hold plastic particles. A driving motor is provided on one side of the mixer to drive the stirring shaft 102 to rotate. The driving motor driving the stirring shaft 102 to rotate is a prior art and will not be elaborated here. The stirring shaft 102 is used to drive the stirring paddle 103 to rotate, so that the stirring paddle 103 can stir the plastic particles in the mixer shell 101, so that the plastic particles and the modifier powder are mixed.
[0043] The adjustment component 200 is arranged on the mixer housing 101, and includes a support member 201, an injection member 202, an inflatable member 203 and an adjustment member 204. The support member 201 is arranged on the mixer housing 101, the injection member 202 is located in the mixer housing 101, the inflatable member 203 is arranged on one side of the injection member 202, and the adjustment member 204 is located in the injection member 202.
[0044] The support member 201 is used to support the mixer housing 101. At the same time, the support member 201 detects the weight of the plastic particles in the mixer housing 101, thereby driving the adjustment member 204. The jet member 202 is used to spray into the mixer housing 101, so that the modifier powder and the plastic particles are in full contact. The inflatable member 203 compresses gas into the jet member 202 through the drive of the stirring shaft 102, so that the stirring shaft 102 stops driving the stirring paddle 103 to rotate, and the inflatable member 203 can also stop compressing gas into the jet member 202, which can avoid unnecessary energy waste, reduce the operating cost of the equipment, reduce the wear of the equipment, and extend the life of the equipment. The adjustment member 204 is used to adjust the air pressure in the jet member 202, so that the jet member 202 automatically adjusts the jet pressure to adapt to the change in the amount of plastic particles in the mixer housing 101.
[0045] Specifically, the support member 201 includes a support leg 201a, a first spring 201b, a support column 201c, a base 201d and an adjustment block 201e. The support leg 201a is fixed to one side of the mixer housing 101, and the two ends of the first spring 201b are respectively fixed to the inner top wall of the support leg 201a and the top of the support column 201c. The support column 201c and the support leg 201a are slidably connected, the support column 201c is fixed to the top of the base 201d, and the adjustment block 201e is fixed to the top of the base 201d.
[0046] The base 201d is used to fix and support the adjustment block 201e and the support column 201c. There are four support legs 201a, which are symmetrically arranged on both sides of the mixer housing 101. The first spring 201b is in a compressed state and is used to support the support legs 201a. The adjustment block 201e is located on one side of the adjustment member 204 and is used to drive the adjustment member 204. When the amount of plastic particles in the mixer housing 101 decreases, the mixer housing 101 can be pushed by the reset force of the first spring 201b, so that the adjustment block 201e is away from the adjustment member 204. At this time, the adjustment member 204 can reduce the air pressure in the jet member 202, thereby reducing the blowing ability of the modifier powder and preventing the modifier powder from "dusting".
[0047] Specifically, the jet component 202 includes a support plate 202a, an air storage box 202b, a support bar 202c, a sealing plate 202d and an air intake pipe 202e. The support plate 202a is fixed to the inner top wall of the mixer housing 101, the air storage box 202b is fixed to the bottom of the support plate 202a, the support bar 202c is fixed to the inner wall of the air storage box 202b, the sealing plate 202d slides between the support bar 202c and the support plate 202a, and the air intake pipe 202e is arranged at the bottom of the air storage box 202b.
[0048] The support plate 202a and the gas storage box 202b are fixedly connected by bolts, and a sealing gasket is provided between the support plate 202a and the gas storage box 202b to prevent the gas in the gas storage box 202b from leaking from the connection between the two. The support plate 202a is provided with a plurality of air holes, and the bottom wall of the mixer housing 101 is also provided with a plurality of air holes. The air holes of the support plate 202a and the mixer housing 101 are interconnected. The support bar 202c is used to support the sealing plate 202d. The sealing plate 202d is provided with a plurality of air holes corresponding to the support plate 202a. The air holes are connected by moving the sealing plate 202d. When the air holes on the sealing plate 202d and the support plate 202a are connected, the gas in the air storage box 202b will be sprayed into the air holes on the inner bottom wall of the mixer shell 101 through the air holes, thereby blowing the modifier powder on the inner bottom wall of the mixer shell 101. When the air holes on the sealing plate 202d and the support plate 202a are not connected, the sealing plate 202d blocks the support plate 202a, so that the gas in the air storage box 202b cannot enter the mixer shell 101 through the support plate 202a.
[0049] Specifically, the jet component 202 also includes a sleeve 202f, a sealing cover 202g, a connecting rod 202h, a second spring 202i, a support plate 202j, an isolation column 202k and a support ring 202l. The sleeve 202f is fixed in the mixer housing 101, the sealing cover 202g is located at the top of the sleeve 202f, the connecting rod 202h is fixed to the bottom of the sealing cover 202g, the two ends of the second spring 202i are respectively fixed to the inner top wall of the sleeve 202f and the top of the support plate 202j, the support plate 202j is fixed to the bottom of the connecting rod 202h, the isolation column 202k is fixed to the top of the support plate 202j, the support ring 202l is fixed to the top of the isolation column 202k, and a through hole U is opened at the top of the sleeve 202f.
[0050] The sleeve 202f is located in the air hole opened in the mixer housing 101, and the gas in the air storage box 202b can enter the sleeve 202f in the air hole of the mixer housing 101 through the support plate 202a.
[0051] When the air pressure in the sleeve 202f increases, the sealing cover 202g can be squeezed through the through hole U, so that the sealing cover 202g moves upward. At this time, the gas in the sleeve 202f can smoothly blow the modifier powder through the air holes of the mixer shell 101. The setting of the isolation column 202k and the support ring 202l can prevent the support plate 202j from blocking the through hole U, so that the gas in the sleeve 202f cannot smoothly enter the air holes of the mixer shell 101.
[0052] When the air holes on the sealing plate 202d and the support plate 202a are not connected, the support plate 202j can be pushed under the action of the return elastic force of the second spring 202i, so that the support plate 202j moves downward. At this time, the support plate 202j can drive the sealing cover 202g to move downward through the connecting rod 202h, so that the sealing cover 202g blocks the through hole U, which can effectively prevent the modifier powder in the mixer housing 101 from entering the sleeve 202f through the through hole U.
[0053] Example 2
[0054] Reference Figure 1 , Figure 5 and Figure 11 to Figure 14 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.
[0055] Specifically, the inflatable member 203 includes a rotating shaft 203a, a first pulley 203b, a second pulley 203c and a partition 203d. The rotating shaft 203a is rotatably connected to the mixer housing 101, the first pulley 203b is fixed to the surface of the stirring shaft 102, the second pulley 203c is fixed to the surface of the rotating shaft 203a, the partition 203d is fixed to the mixer housing 101, and the first pulley 203b and the second pulley 203c are connected by a belt.
[0056] The partition 203d is used to isolate the first pulley 203b from the belt. When the stirring shaft 102 rotates, the second pulley 203c can be driven to rotate by the first pulley 203b, so that the second pulley 203c drives the rotating shaft 203a to rotate.
[0057] Specifically, the inflatable member 203 also includes a compression tube 203e, an air guide tube 203f, a one-way valve 203g and a compression plug 203h. The compression tube 203e is fixed to the end of the air intake pipe 202e, the air guide tube 203f is arranged in the compression tube 203e, the one-way valve 203g is arranged on the air intake pipe 202e and the air guide tube 203f, and the compression plug 203h slides in the compression tube 203e.
[0058] The compression pipe 203e is connected to the air intake pipe 202e, and the air guide pipe 203f is connected to the compression pipe 203e. The one-way valve 203g is a prior art, and its specific structure is not shown in the figure. The one-way valve 203g on the air guide pipe 203f allows the air in the air guide pipe 203f to flow into the compression pipe 203e from the outside, and the one-way valve 203g on the air intake pipe 202e allows the air in the air intake pipe 202e to flow from the compression pipe 203e to the air intake pipe 202e, and cannot flow in the reverse direction. When the compression plug 203h When it moves into the compression tube 203e, the air in the compression tube 203e can be compressed into the intake pipe 202e. When the compression plug 203h moves toward the outside of the compression tube 203e, the air pressure in the compression tube 203e decreases. At this time, the outside air enters the compression tube 203e through the air guide tube 203f to fill the air for the compression tube 203e. Through the reciprocating movement of the compression plug 203h, the air in the compression tube 203e can be continuously compressed into the intake pipe 202e, thereby providing gas for the air storage box 202b.
[0059] Specifically, the inflatable member 203 also includes a limiting sleeve 203i, an extrusion sleeve 203j and a driving block 203k. The limiting sleeve 203i is fixed in the mixer housing 101, the extrusion sleeve 203j slides in the limiting sleeve 203i, the driving block 203k is fixed to the surface of the rotating shaft 203a, and a reciprocating groove V is opened in the extrusion sleeve 203j.
[0060] The compression plug 203h is fixed at the end of the extrusion sleeve 203j, and the limiting sleeve 203i is used to limit the extrusion sleeve 203j so that the extrusion sleeve 203j can move stably. When the rotating shaft 203a rotates, it can drive the driving block 203k to move in the reciprocating groove V of the extrusion sleeve 203j, thereby driving the extrusion sleeve 203j to move back and forth, so that the extrusion sleeve 203j drives the compression plug 203h to move back and forth.
[0061] Example 3
[0062] Reference Figure 4 and Figure 6 to Figure 10 , which is the third embodiment of the present invention, and is based on the first two embodiments.
[0063] Specifically, the adjusting member 204 includes a driving seat 204a, a sealing tube 204b, a third spring 204c, a sleeve 204d and a supporting seat 204e. The driving seat 204a is fixed to the bottom of the sealing plate 202d, the sealing tube 204b is fixed to one side of the driving seat 204a, two ends of the third spring 204c are respectively fixed to the inner wall of the sealing tube 204b and the inner wall of the sleeve 204d, the sleeve 204d slides in the sealing tube 204b, and the supporting seat 204e is fixed to the end of the sleeve 204d.
[0064] The driving seat 204a is used to drive the sealing plate 202d to move, so as to control whether the sealing plate 202d blocks the air holes of the supporting plate 202a. The sealing tube 204b slides in the air storage box 202b, and the connection between the sealing tube 204b and the air storage box 202b is sealed. The third spring 204c is in a compressed state. The supporting seat 204e is located on one side of the adjusting block 201e. The adjusting block 201e is used to adjust the position of the supporting seat 204e. When the air in the air storage box 202b When the pressure increases, the sealing tube 204b can be squeezed toward the outside of the air storage box 202b, so that the sealing tube 204b further compresses the third spring 204c. While the sealing tube 204b moves, the sealing plate 202d can be driven to move by the driving seat 204a, so that the air holes of the sealing plate 202d and the support plate 202a are connected. At this time, the gas in the air storage box 202b can enter the mixer housing 101, thereby blowing the modifier powder on the inner bottom wall of the mixer housing 101.
[0065] When the amount of plastic particles in the mixer housing 101 decreases, the mixer housing 101 will move upward. At this time, the adjustment block 201e and the support seat 204e will move away from each other, so that the squeezing force of the support seat 204e on the third spring 204c is reduced. At this time, the third spring 204c will be released, so that the elastic force of the third spring 204c is reduced. At this time, the gas in the air storage box 202b can more easily push the sealing tube 204b. In order to make the air holes of the sealing plate 202d and the support plate 202a connected, the gas pressure in the air storage box 202b is required to be lower, so that the flow rate of the air flow sprayed into the mixer housing 101 is lower, reducing the blowing force on the modifier powder on the inner bottom wall of the mixer housing 101 and preventing the occurrence of "dust".
[0066] Specifically, the adjusting member 204 also includes a positioning sleeve 204f, a fixing block 204g and a positioning rod 204h. The positioning sleeve 204f is fixed to one side of the support seat 204e, the fixing block 204g is fixed to the bottom of the mixer housing 101, the positioning rod 204h is fixed between the two fixing blocks 204g, and the positioning sleeve 204f slides on the surface of the positioning rod 204h.
[0067] Both ends of the positioning rod 204h are provided with fixing blocks 204g, and both sides of the support seat 204e are fixed with positioning sleeves 204f. The positioning sleeves 204f slide on the surface of the positioning rod 204h, so that the support seat 204e can move stably.
[0068] Specifically, the adjusting member 204 also includes an adjusting rod 204i, a positioning ring 204j and a support pad 204k. The adjusting rod 204i is fixed to the inner wall of the sleeve 204d, the positioning ring 204j is fixed to the surface of the adjusting rod 204i, the support pad 204k is fixed to the inner wall of the mixer housing 101, and a flow channel W is opened in the adjusting rod 204i.
[0069] When the amount of plastic particles in the mixer housing 101 is less than the threshold value, the mixer housing 101 will move upward. At this time, the adjusting block 201e and the support seat 204e will be completely separated. Under the action of the reset elastic force of the third spring 204c, the sliding sleeve 204d can be pushed away from the sealing tube 204b, so that the sliding sleeve 204d synchronously drives the adjusting rod 204i to move, so that the adjusting rod 204i drives the positioning ring 204j to move, so that the positioning ring 204j is attached to one side of the air storage box 202b. At this time, the flow channel W port opened in the adjusting rod 204i moves to the position of the support pad 204k, so that the gas in the air storage box 202b continuously flows out through the flow channel W, so that the air pressure in the air storage box 202b cannot reach the pressure that pushes the sealing tube 204b to move so that the air holes of the sealing plate 202d and the support plate 202a are connected, thereby stopping the gas from being sprayed into the mixer housing 101.
[0070] During use, when mixing plastic particles and modifiers, first add the plastic particles into the mixer housing 101, start the drive motor, so that the stirring shaft 102 drives the stirring paddle 103 to rotate, so that the stirring paddle 103 breaks up the plastic particles, and then add a certain amount of modifier powder to the mixer housing 101. Under the stirring of the stirring paddle 103, the plastic particles will begin to mix with the modifier powder.
[0071] While the stirring shaft 102 is rotating, the stirring shaft 102 can drive the second pulley 203c to rotate through the first pulley 203b, so that the second pulley 203c drives the rotating shaft 203a to rotate. When the rotating shaft 203a rotates, it can drive the driving block 203k to move in the reciprocating groove V of the extrusion sleeve 203j, thereby driving the extrusion sleeve 203j to reciprocate, so that the extrusion sleeve 203j drives the compression plug 203h to reciprocate. The reciprocating movement of the compression plug 203h can make the air in the compression pipe 203e be continuously compressed into the intake pipe 202e, thereby providing gas for the air storage box 202b.
[0072] As the air pressure in the air storage box 202b increases, the sealing tube 204b can be squeezed toward the outside of the air storage box 202b, so that the sealing tube 204b further compresses the third spring 204c. When the sealing tube 204b moves, the sealing plate 202d can be driven to move by the driving seat 204a, so that the air holes of the sealing plate 202d and the support plate 202a are connected, and the gas in the air storage box 202b can enter the sleeve 202f in the air hole of the mixer housing 101 through the support plate 202a. The air pressure in 2f increases, and the sealing cover 202g can be squeezed through the through hole U, so that the sealing cover 202g moves upward. At this time, the gas in the sleeve 202f can smoothly pass through the air holes of the mixer shell 101 to blow the modifier powder, so that the modifier powder leaves the bottom wall of the mixer shell 101. Under the stirring of the stirring paddle 103, the plastic particles and the blown modifier powder can be mixed together. When the mixing is completed, the mixture can be discharged for use through the discharge port set on one side of the mixer shell 101.
[0073] Since the amount of plastic particles added to the mixer housing 101 each time is not a constant value, it is necessary to automatically adjust the air pressure of the jet to avoid the generation of "dust" when the amount of plastic particles is too small.
[0074] When the amount of plastic particles added to the mixer housing 101 is small, the mixer housing 101 can be lifted up under the push of the reset elastic force of the first spring 201b, and the support seat 204e moves away from the adjusting block 201e, so that the squeezing force of the support seat 204e on the third spring 204c is reduced. At this time, the third spring 204c is released, so that the elastic force of the third spring 204c is reduced. At this time, the gas in the air storage box 202b can more easily push the sealing tube 204b. In order to connect the air holes of the sealing plate 202d and the support plate 202a, the gas pressure in the air storage box 202b is required to be lower, so that the flow rate of the air flow sprayed into the mixer housing 101 is lower, and the blowing force on the modifier powder on the inner bottom wall of the mixer housing 101 is reduced to prevent the occurrence of "dust".
[0075] When the amount of plastic particles added to the mixer housing 101 is lower than the threshold value, the mixer housing 101 will move upward. At this time, the adjusting block 201e and the support seat 204e will be completely separated. Under the action of the reset elastic force of the third spring 204c, the sliding sleeve 204d can be pushed away from the sealing tube 204b, so that the sliding sleeve 204d synchronously drives the adjusting rod 204i to move, so that the adjusting rod 204i drives the positioning ring 204j to move, so that the positioning ring 204j is attached to one side of the air storage box 202b. At this time, the flow channel W port opened in the adjusting rod 204i moves to the position of the support pad 204k, so that the gas in the air storage box 202b continuously flows out through the flow channel W, so that the air pressure in the air storage box 202b cannot reach the pressure that pushes the sealing tube 204b to move so that the air holes of the sealing plate 202d and the support plate 202a are connected, thereby stopping the gas from being sprayed into the mixer housing 101.
