After the counterweight block moves, the second pull rope is in a relaxed state, and the third elastic member pushes the winding gear to move through the winding rod, so that the winding gear is meshed with the fixed gear. The material storage drum drives the winding gear to move circumferentially around the fixed gear. During the movement of the winding gear, the winding rod is driven to rotate, so that the first pull rope is wound around the winding rod, and then the pull rod can be pulled up; when the pull rod moves to the top of the longitudinal rod, the pull rod can no longer move, so that the winding rod has no The method continues to rotate, and at this time the winding gear continuously pushes the winding rod to move away from the fixed gear during the circumferential movement around the fixed gear, and the third elastic member pushes the winding rod to move toward the fixed gear, so that when the pressure rod position is locked, the winding gear will not interfere with the fixed gear; when the material storage barrel stops rotating, the fourth elastic member pulls the counterweight block to move toward the fixed gear, and the counterweight block pulls the winding rod to move away from the fixed gear through the second pull rope, and the winding rod drives the winding gear to move and disengage from the fixed gear.

[0038] The following is combined with Figure 1-Figure 10 This application is described in further detail.

[0039] The embodiment of the present application discloses a material pretreatment device for injection molding equipment.

[0040] Reference Figure 1 A feeding pretreatment device for injection molding equipment includes a stirring barrel 1 with an opening at the top, four legs 29 are fixedly installed at the bottom of the stirring barrel 1, a barrel cover 27 is installed at the open end of the top of the stirring barrel 1, a discharge pipe 28 is installed at the bottom of the stirring barrel 1, and a switch valve is installed on the discharge pipe 28.

[0041] Reference Figure 1 and Figure 2 A driving member 2 is fixedly installed in the middle of the bottom wall of the mixing barrel 1, and a stirring shaft 3 is installed in the mixing barrel 1 to rotate along its own axis direction. The bottom end of the stirring shaft 3 is fixedly connected to the driving member 2, and a plurality of stirring blades 4 are fixedly installed on the stirring shaft 3. In the present application, the driving member 2 can be selected as a servo motor. The driving member 2 drives the plurality of stirring blades 4 to rotate through the driving shaft, and the stirring blades 4 can stir and mix a variety of raw material particles.

[0042] Reference Figure 2 and Figure 3A circular track 30 is fixedly installed on the inner wall of the mixing barrel 1, and a material storage barrel 5 with an open top is coaxially installed on the top of the inner cavity of the mixing barrel 1, and the material storage barrel 5 is rotatably installed on the circular track 30. A transmission assembly 6 is installed in the mixing barrel 1, and the transmission assembly 6 is connected to the mixing shaft 3 and the material storage barrel 5. When the mixing shaft 3 rotates, the mixing shaft 3 can drive the material storage barrel 5 to rotate in the mixing barrel 1 through the transmission assembly 6.

[0043] Reference Figure 2 , Figure 4 and Figure 5 Four partitions 7 are fixedly installed at equal intervals along the circumference of the storage barrel 5. The partitions 7 are installed along the diameter direction of the storage barrel 5, and the four partitions 7 divide the inner cavity of the storage barrel 5 into four storage chambers 8. A blanking plate 10 is installed in the bottom wall of each storage chamber 8 of the storage barrel 5, and a blanking port 9 is opened at one end of the blanking plate 10 close to the outer peripheral wall of the storage barrel 5.

[0044] When a plurality of raw materials are stirred and mixed, the plurality of raw materials are first placed in a plurality of storage chambers 8 of the storage barrel 5, and the driving member 2 drives the storage barrel 5 to rotate through the stirring shaft 3 and the transmission assembly 6, and the plurality of raw materials rotate and fall into the stirring barrel 1 through the plurality of discharge ports 9, so that the plurality of raw materials can be preliminarily mixed. The stirring shaft 3 then drives the stirring blade 4 to rotate, and the stirring blade 4 stirs and mixes the plurality of raw materials in the stirring barrel 1 again, thereby improving the stirring and mixing effect of the plurality of raw materials.

[0045] A retaining ring 31 is fixedly mounted on the inner wall of the mixing barrel 1, and the inner side of the retaining ring 31 is tilted downward. The retaining ring 31 is located directly below the feeding port 9 and above the stirring blade 4. The raw material particles falling from the feeding port 9 first fall on the retaining ring 31, and the raw material particles are rebounded to the middle of the mixing barrel 1 under the action of the retaining ring 31. At this time, the rotating stirring blade 4 will break up the raw material particles, thereby further improving the mixing effect of multiple raw material particles.

[0046] Reference Figure 2 and Figure 3 Specifically, the transmission assembly 6 includes a fixed frame 61, a connecting column 62, a mounting plate 63, a driving gear 64, a gear ring 65 and three driven gears 66. The fixed frame 61 is fixedly installed on the top of the mixing barrel 1 and is located above the storage barrel 5. The connecting column 62 is fixedly installed on the middle part of the bottom wall of the fixed frame 61 along the axial direction of the mixing barrel 1. The connecting column 62 passes through the storage barrel 5, and the mounting plate 63 is fixedly installed on the bottom end of the connecting column 62 and is located outside the bottom end of the storage barrel 5.

[0047] The driving gear 64 is fixedly mounted on the top of the stirring shaft 3, and three driven gears 66 are rotatably mounted on the bottom wall of the mounting plate 63. The three driven gears 66 are arranged in a circumferential array on the outer peripheral side of the driving gear 64, and each driven gear 66 is meshed with the driving gear 64. The gear ring 65 is fixedly mounted on the bottom wall of the storage barrel 5, and the three driven gears 66 are meshed with the inner side of the gear ring 65. The mounting plate 63 is fixedly mounted in the stirring barrel 1 through the connecting column 62 and the fixing frame 61. The stirring shaft 3 drives the three driven gears 66 to rotate through the driving gear 64, and the three driven gears 66 then drive the storage barrel 5 to rotate through the gear ring 65.

[0048] Reference Figure 4 and Figure 5 , a slide plate 11 is slidably installed in the blanking plate 10 along its length direction, and a driving assembly 12 is installed on the mounting plate 63, and the driving assembly 12 includes four first magnetic parts 121, twelve second magnetic parts 122 and a third magnetic part 123. The four first magnetic parts 121 are fixedly installed in the middle of the side wall of the four slide plates 11 close to the mounting plate 63, the twelve second magnetic parts 122 are fixedly installed on the outer peripheral side wall of the mounting plate 63 at equal intervals along the circumference of the mounting plate 63, and the twelve third magnetic parts 123 are fixedly installed on the outer peripheral side wall of the mounting plate 63 at equal intervals along the circumference of the mounting plate 63, and each second magnetic part 122 is located between two adjacent third magnetic parts 123. In the present application, the first magnetic part 121, the second magnetic part 122 and the third magnetic part 123 can all be selected as magnets, and the first magnetic part 121 and the second magnetic part 122 attract each other, and the first magnetic part 121 and the third magnetic part 123 repel each other.

[0049] When the storage barrel 5 rotates, the storage barrel 5 drives the four slides 11 to rotate synchronously. The mounting plate 63 is fixed in the mixing barrel 1 through the connecting column 62 and the fixing frame 61. During the rotation of the storage barrel 5, the multiple second magnetic parts 122 and the third magnetic parts 123 on the mounting plate 63 will remain stationary. The slide 11 drives the first magnetic part 121 to move circumferentially around the mounting plate 63. The first magnetic part 121 will pass through the multiple second magnetic parts 122 and the third magnetic parts 123 in sequence. When the first magnetic part 121 moves to the second magnetic part 122, and the first magnetic part 121 and the second magnetic part 122 are located on the same straight line along the diameter direction of the mounting plate 63, the second magnetic part 122 attracts the first magnetic part 121 and drives the slide 11 to move toward the mounting plate 63. At this time, the discharge port 9 is opened. When the first magnetic member 121 moves to the third magnetic member 123, and the first magnetic member 121 and the third magnetic member 123 are located on the same straight line along the diameter direction of the mounting disk 63, the third magnetic member 123 repels the first magnetic member 121 and drives the slide plate 11 to move away from the mounting disk 63, and the feed port 9 is closed at this time. The feed port 9 is continuously opened and closed during the movement of the slide plate 11. During the continuous reciprocating movement of the slide plate 11, the raw material particles in the feed port 9 are squeezed, so that the raw material particles are not easy to block the feed port 9. At the same time, when the slide plate 11 closes the feed port 9, there will be raw material particles in the feed port 9. At this time, the slide plate 11 will not completely close the feed port 9. The slide plate 11 will squeeze the raw material particles in the feed port 9, which can also achieve the effect that the raw material particles are not easy to block the feed port 9.

[0050] Reference Figure 6 and Figure 7 The middle part of the outer wall of the storage barrel 5 is concave inward along its own circumference and is wavy. On the section along the diameter direction of the storage barrel 5, the wavy outer wall of the storage barrel 5 has twelve peaks and twelve troughs. The peaks are protruding toward the outside of the storage barrel 5, and the troughs are concave toward the inside of the storage barrel 5. Twelve installation grooves 40 are evenly spaced along its own circumference on the inner wall of the mixing barrel 1. A fixing sleeve 13 is fixedly installed in each installation groove 40. A sliding rod 14 is slidably installed in each fixing sleeve 13 along the diameter direction of the mixing barrel 1. The twelve fixing sleeves 13 correspond to the twelve third magnetic members 123 along the diameter direction of the storage barrel 5.

[0051] A bracket 32 ​​is fixedly installed at the end of the slide bar 14 away from the fixed sleeve 13, and a roller 16 is rotatably installed in the bracket 32. A first elastic member 15 is sleeved on the fixed sleeve 13, and the two ends of the first elastic member 15 respectively abut against the inner wall of the mixing barrel 1 and the bracket 32. In the present application, the first elastic member 15 can be selected as a spring, and the first elastic member 15 pushes the roller 16 to move through the bracket 32, so that during the rotation of the storage barrel 5, the roller 16 always rolls and fits on the wavy outer wall of the storage barrel 5.

[0052] When the various raw materials in the mixing barrel 1 are mixed and discharged from the discharge pipe 28, the driving member 2 is turned off, and the storage barrel 5 continues to rotate due to inertia, and the rotation speed of the storage barrel 5 gradually decreases until it stops rotating. The first magnetic member 121 corresponds to the trough of the wavy outer wall of the storage barrel 5 along the diameter direction of the storage barrel 5. When the material storage barrel 5 is about to stop rotating, the first elastic member 15 pushes the roller 16 to move, and the roller 16 rolls to the trough of the wavy outer wall of the material storage barrel 5. When the material storage barrel 5 stops completely, the fixed sleeve 13 corresponds to the trough of the wavy outer wall. Because the trough of the wavy outer wall corresponds to the first magnetic member 121, and the fixed sleeve 13 corresponds to the third magnetic member 123, the first magnetic member 121 on the slide plate 11 corresponds to the third magnetic member 123. The third magnetic member 123 acts on the slide plate 11 through the first magnetic member 121. The slide plate 11 moves and closes the discharge port 9, so that when the raw materials are poured into the material storage barrel 5 again, the raw materials will not leak out from the discharge port 9.

[0053] Reference Figure 4 and Figure 5 The two side walls of the blanking plate 10 along the width direction and located near the blanking port 9 are fixedly mounted with connecting shafts 17. The blanking plate 10 is rotatably mounted in the bottom wall of the storage barrel 5 through two shafts with the axis parallel to the tangent direction of the storage barrel 5 as the axis. Four support frames 18 are fixedly mounted on the bottom wall of the storage barrel 5, and the four support frames 18 are respectively located below the four blanking plates 10.

[0054] Reference Figure 8 and Fig. 9 A second elastic member 21 is installed at the bottom of the inner cavity of the support frame 18, and a lifting plate 20 is installed in the support frame 18 in a vertically slidable manner. The bottom end of the lifting plate 20 abuts against the top of the second elastic member 21, and the top of the lifting plate 20 abuts against the side of the bottom wall of the blanking plate 10 away from the blanking port 9. In the present application, the second elastic member 21 can be selected as a spring.

[0055] When the raw material particles are poured into the storage chamber 8, the raw material particles press down the blanking plate 10, and the blanking plate 10 presses down the lifting plate 20. The lifting plate 20 moves downward in the support frame 18 and squeezes the second elastic member 21. The second elastic member 21 shrinks and deforms and stores elastic potential energy. At this time, the blanking plate 10 is in a horizontal state.

[0056] When most of the raw material particles have been discharged, the second elastic member 21 releases its elastic potential energy and pushes the lifting plate 20 to move upward. The lifting plate 20 abuts against the discharge plate 10 and pushes the discharge plate 10 to rotate. At this time, a larger discharge port appears between the end of the discharge plate 10 close to the discharge port 9 and the bottom wall of the storage barrel 5. The raw material particles on the discharge plate 10 are discharged from the storage chamber 8 from the discharge port along the inclined direction of the discharge plate 10, so that it is not easy for raw material particles to remain in the storage chamber 8.

[0057] The storage barrel 5 is located on the inner wall of each storage chamber 8, and a cross bar 22 is fixedly installed along the diameter direction of the storage barrel 5. The end of the cross bar 22 away from the inner wall of the storage barrel 5 is fixedly installed with a longitudinal bar 23 in the vertical direction. A pressure rod 24 is slidably installed in the longitudinal bar 23 along the vertical direction. The bottom end of the pressure rod 24 extends to the outside of the longitudinal bar 23, and the pressure rod 24 is located above the blanking plate 10. The storage barrel 5 is equipped with four reset assemblies 25 corresponding to the four pressure rods 24. When the storage barrel 5 rotates, the reset assembly 25 drives the pressure rod 24 to move upward. When the pressure rod 24 moves to the top of the longitudinal bar 23, the reset assembly 25 locks the pressure rod 24. When the storage barrel 5 stops rotating, the reset assembly 25 releases the lock on the pressure rod 24, and the pressure rod 24 slides downward under gravity and pushes the blanking plate 10 to rotate to a horizontal state.

[0058] Reference Figure 8 , Fig. 9 and Fig.10 Specifically, the reset assembly 25 includes a first pull rope 251, a winding rod 252, a winding gear 253, a fixed gear 254, a third elastic member 255, a second pull rope 256, a rotating wheel 257, a counterweight block 258 and a fourth elastic member 259. A cylindrical mounting cavity 26 is formed in the middle of the storage barrel 5 along its own axial direction. The storage barrel 5 is located at the top closed opening of the mounting cavity 26 and the bottom open opening of the mounting cavity 26. The connecting column 62 passes through the top closed opening of the mounting cavity 26 and extends into the mounting cavity 26, and the mounting plate 63 is located at the bottom end of the mounting cavity 26.

[0059] One end of the first pull rope 251 is fixedly connected to the top of the pressure rod 24, and the other end of the first pull rope 251 passes through the longitudinal rod 23 and the cross rod 22 and extends into the installation cavity 26 of the storage barrel 5. The storage barrel 5 is located in the installation cavity 26, and the first support ring 33, the second support ring 34 and the third support ring 35 are fixedly installed in sequence from top to bottom along the axis direction of the storage barrel 5. The width of the first support ring 33 is the same as that of the third support ring 35, and the width of the second support ring 34 is smaller than that of the first support ring 33, and the inner peripheral side of the top wall of the second support ring 34 is bent upward to form a flange 36.

[0060] The first support ring 33 and the third support ring 35 are each provided with four slide grooves 37 at equal intervals along their own circumferences. A slider 38 is slidably installed in each slide groove 37 along the diameter direction of the storage barrel 5. The upper and lower ends of the winding rod 252 are rotatably connected to the sliders 38 in the first support ring 33 and the third support ring 35 respectively. A winding drum 39 is fixedly installed on the winding rod 252, and the end of the first pull rope 251 away from the pressure rod 24 is fixedly connected to the winding drum 39.

[0061] The fixed gear 254 is fixedly mounted on the connecting column 62, the winding gear 253 is fixedly mounted on the winding rod 252, the third elastic member 255 is mounted in the slide groove 37 of the first support ring 33 and the third support ring 35, and the third elastic member 255 is located on the side of the slider 38 away from the fixed gear 254. In the present application, the third elastic member 255 can be selected as a spring. The third elastic member 255 pushes the winding rod 252 to move through the slider 38, and the winding rod 252 drives the winding gear 253 to move toward the fixed gear 254 and makes the winding gear 253 mesh with the fixed gear 254.

[0062] When the material storage barrel 5 rotates, the material storage barrel 5 drives the winding gear 253 to move along the circumferential direction of the fixed gear 254. During the movement of the winding gear 253, the winding rod 252 is driven to rotate. The winding rod 252 drives the winding disk 39 to rotate. The winding disk 39 winds up the first pull rope 251, so that the first pull rope 251 can pull the pressure rod 24 to move upward.

[0063] When the pressure rod 24 moves to the top of the longitudinal rod 23, the pressure rod 24 cannot continue to move upward, and the pressure rod 24 pulls the winding disk 39 through the first pull rope 251, so that the winding rod 252 can no longer rotate. When the winding gear 253 moves circumferentially around the fixed gear 254, since the winding gear 253 cannot move, the winding gear 253 moves away from the fixed gear 254 during the movement, so that the winding gear 253 can move normally. After the winding gear 253 moves away from the fixed gear 254, the third elastic member 255 pushes the winding gear 253 to move toward the fixed gear 254 again, so that the pressure rod 24 will not move downward, thereby locking the pressure rod 24.

[0064] One end of the fourth elastic member 259 is fixedly mounted on the side of the flange 36 of the second support ring 34 away from the fixed gear 254, and the counterweight 258 is fixedly mounted on the end of the fourth elastic member 259 away from the flange 36, and the counterweight 258 is slidably mounted on the top wall of the second support ring 34 along the diameter direction of the storage barrel 5. The rotating wheel 257 is mounted on the second support ring 34 and is located on the side of the counterweight 258 away from the fourth elastic member 259. Two rotating wheels 257 are installed, and the two rotating wheels 257 are respectively located on the upper and lower sides of the second support ring 34. One end of the second pull rope 256 is fixedly connected to the counterweight 258, and the other end of the second pull rope 256 first passes through the rotating wheel 257 above the second support ring 34 and passes through the second support ring 34, and then passes through the rotating wheel 257 below the second support ring 34 and is rotatably sleeved on the winding rod 252. In the present application, the fourth elastic member 259 can be selected as a spring.

[0065] When the material storage barrel 5 rotates, the material storage barrel 5 drives the counterweight block 258 to rotate, and the counterweight block 258 is moved away from the fixed gear 254 by the centrifugal force. During the movement of the counterweight block 258, the fourth elastic member 259 is pulled, and the fourth elastic member 259 is stretched and deformed and stores elastic potential energy. When the counterweight block 258 moves, the second pull rope 256 is in a relaxed state, so that the third elastic member 255 can push the winding gear 253 to mesh with the fixed gear 254.

[0066] When the storage barrel 5 stops rotating, the fourth elastic member 259 pulls the counterweight 258 to move toward the fixed gear 254. The counterweight 258 pulls the second pull rope 256 during the movement, so that the second pull rope 256 is changed into a taut state. The second pull rope 256 then pulls the winding rod 252 to move away from the fixed gear 254. The winding rod 252 drives the winding gear 253 to move, so that the winding gear 253 is disengaged from the fixed gear 254. At this time, the locking of the pressure rod 24 is released, so that the pressure rod 24 can move downward under the action of gravity.

[0067] The implementation principle of the feed pretreatment device of an injection molding equipment in the embodiment of the present application is as follows: when stirring and mixing a variety of raw materials, the various raw materials are first placed in a plurality of storage chambers 8 of the storage barrel 5 respectively, the driving member 2 drives the driving gear 64 to rotate through the stirring shaft 3, the driving gear 64 drives the three driven gears 66 to rotate, and the three driven gears 66 then drive the storage barrel 5 to rotate through the ring gear 65. During the rotation of the storage barrel 5, the various raw materials rotate through the plurality of discharge ports 9 and fall into the stirring barrel 1 respectively, so that the various raw materials can be preliminarily mixed, the stirring shaft 3 then drives the stirring blade 4 to rotate, and the stirring blade 4 stirs and mixes the various raw materials in the stirring barrel 1 again, thereby improving the stirring and mixing effect of the various raw materials. During the process of the raw material falling through the discharge port 9, the storage barrel 5 drives the first magnetic member 121 to move circumferentially around the mounting plate 63 through the slide plate 11. When the first magnetic member 121 moves through the second magnetic member 122 and the third magnetic member 123, the second magnetic member 122 and the third magnetic member 123 absorb and repel the first magnetic member 121, so that the slide plate 11 can reciprocate in the direction of approaching and moving away from the mounting plate 63, and then squeeze the raw material particles in the discharge port 9, so that the raw material particles are not easy to block the discharge port 9. When most of the raw material particles are discharged, the second elastic member 21 releases elastic potential energy and pushes the lifting plate 20 to move upward, and the lifting plate 20 abuts against the discharge plate 10 and pushes the discharge plate 10 to rotate. At this time, a larger discharge port appears between the end of the discharge plate 10 close to the discharge port 9 and the bottom wall of the storage barrel 5, and the raw material particles on the discharge plate 10 are discharged from the discharge port to the storage chamber 8 along the inclined direction of the discharge plate 10, so that it is not easy for raw material particles to remain in the storage chamber 8. When all the mixed raw materials are discharged from the mixing barrel and the storage barrel 5 stops rotating, the fourth elastic member 259 pulls the counterweight block 258 to move toward the fixed gear 254. During the movement of the counterweight block 258, the second pull rope 256 is pulled, so that the second pull rope 256 is turned into a taut state. The second pull rope 256 then pulls the winding rod 252 to move away from the fixed gear 254. The winding rod 252 drives the winding gear 253 to move, so that the winding gear 253 is disengaged from the fixed gear 254. At this time, the locking of the pressure rod 24 is released, so that the pressure rod 24 can move downward under the action of gravity, and the pressure rod 24 presses down the unloading plate 10, so that the unloading plate 10 rotates to a horizontal state and closes the discharge port between the unloading plate 10 and the storage barrel 5.

[0068] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
