Description

Technical Field

[0001] The invention relates to the technical field of multi-production line feeding, and in particular to a multi-production line feeding device for plastic products. Background Art

[0002] Plastic products are usually produced by mixing plastic masterbatch, color masterbatch and additives. In order to improve production efficiency, multiple production lines are used for feeding. Advanced automation technology and control systems are used to realize full automation of multiple production line feeding. Due to different production workshop layouts and production line settings have different requirements for material lifting heights, lifting dumpers can be used for feeding. The lifting height of the lifting dumper can usually be adjusted according to actual conditions to adapt to various complex workshop layouts. It can lift the plastic masterbatch to a suitable height to smoothly feed each production line and cooperate with various sensors to quickly lift it to a suitable height.

[0003] Application No. CN202311234989.8 proposes a positioning system for a lifting feeder. When the barrel moves along with the sliding frame, the guide rod always slides along the first guide groove, and the first guide groove limits the random sliding of the slider, so that before the barrel reaches the unloading station, the sealing plate remains in a sealed state for the bottom opening of the barrel, thereby achieving the purpose of ensuring the safe transportation of materials.

[0004] However, when the lifting feeder moves to the unloading station, the sealing plate keeps sealing the bottom opening of the barrel. The plastic masterbatch in the barrel squeezes the plastic masterbatch at the barrel mouth under the action of gravity, causing the plastic masterbatch to be compacted at the barrel mouth and causing blockage, thereby reducing the adding speed of the plastic masterbatch. Summary of the invention

The plastic masterbatch inside the barrel is arranged above the spreading sheets.

[0020] Compared with the prior art, the present invention has the following beneficial technical effects:

[0021] In the present invention, when the plastic masterbatch inside the barrel flows normally, the bearing plate is pressed down by the plastic masterbatch below the inclined limiting block. When the plastic masterbatch is blocked, at this time, the plastic masterbatch on the bearing plate keeps falling, while the plastic masterbatch inside the barrel no longer falls. At this time, the bearing plate moves from below the inclined limiting block to above the inclined limiting block. After the bearing plate resets, vibration is generated, so that the dredging plate moves reciprocally. When the dredging plate moves upward, due to the resistance of the plastic masterbatch, the dredging plate is pressed against the anti - seepage blocking block. When the dredging plate moves downward, the dredging plate rotates under the resistance of the plastic masterbatch and separates from the anti - seepage blocking block. At this time, the dredging plate pulls down the plastic masterbatch, thereby dredging the blocked plastic masterbatch.

[0022] Further, the plastic masterbatch on the bearing plate falls onto the fan plate. The fan plate is impacted by the gravitational potential energy of the plastic masterbatch and rotates, compressing the torsion spring, so that the fan plate continuously fluctuates. Since multiple fan plates are all inclined and annularly distributed at equal angles on the arc surface of the central block, the directions in which the plastic masterbatch bounces on each fan plate are different, thus scattering the plastic masterbatch. The vibration of the fan plate is used to disperse plastic masterbatches of different sizes, so that the plastic masterbatch, color masterbatch and additives are fully and evenly mixed, ensuring the consistency and stability of the performance of plastic products, reducing the required stirring time, and improving production efficiency.

[0023] Furthermore, when the plastic masterbatch inside the barrel is about to be completely discharged, the amount of the plastic masterbatch falling inside the barrel is small, and the downward pressure of the plastic masterbatch on the bearing plate decreases. At this time, the guide block moves upward, and the guide block drives the vibrating rod to impact the spreading plate through the ring. Since the amount of the plastic masterbatch inside the barrel is small at this time, the pressure of the plastic masterbatch on the spreading plate is small, so the spreading plate is pushed up, and the vibrating rod impacts the spreading plate to make it vibrate, thereby vibrating off the plastic masterbatch sticking to the spreading plate, avoiding the influence of the residual plastic masterbatch on the ratio of the plastic masterbatch, color masterbatch and additives.

[0039] Example 1

[0040] This embodiment provides a feeding device for multiple production lines of plastic products, as Figure 1 and 2 shown, which includes a lifting platform 1. A universal wheel 2 is rotatably connected to the bottom of the lifting platform 1. A lifting plate 3 is fixedly installed on the top of the lifting platform 1. A lifting block 4 is slidably connected to the side of the lifting plate 3. A rotating disk 5 is rotatably connected to the side of the lifting block 4 away from the lifting plate 3. The rotating disk 5 is fixedly connected to a material cylinder 6 through a straight rod. Plastic masterbatch is stored inside the material cylinder 6. By raising and lowering the lifting block 4, the height of the material cylinder 6 is changed, and by rotating the rotating disk 5, the opening direction of the material cylinder 6 is changed, so as to move the material cylinder 6 to discharge the material inside it.

[0041] As Figure 3 and 4 shown, a dredging component 7 is arranged inside the material cylinder 6. The dredging component 7 includes a bearing plate 71, a spiral spring 73, an inclined plane 74, an inclined limiting block 75, a first spring 76, a fluctuating part, an anti-seepage blocking block 713 and a dredging plate 714. A support shaft 72 is fixedly installed at the connection between the bearing plate 71 and the spiral spring 73. The support shaft 72 is rotatably connected to the material cylinder 6. The spiral spring 73 is elastically connected between the bearing plate 71 and the material cylinder 6. As Figure 6 shown, the bearing plate 71 is horizontally arranged at the opening of the material cylinder 6. When the plastic masterbatch in the material cylinder 6 falls onto the bearing plate 71, the plastic masterbatch presses down the bearing plate 71 to make the bearing plate 71 rotate and compress the spiral spring 73. When the plastic masterbatch in the material cylinder 6 continuously presses down the bearing plate 71 and the plastic masterbatch in the material cylinder 6 is blocked, the plastic masterbatch will no longer fall. At this time, the elastic force of the spiral spring 73 resets the bearing plate 71.

[0042] As Figure 5 and 6 shown, a baffle is fixedly installed on the top of the bearing plate 71. The baffle blocks the plastic masterbatch falling onto the bearing plate 71 to gather and collect the plastic masterbatch to prevent the plastic masterbatch from scattering. There is a notch on the baffle, and there is a gap between the bearing plate 71 and the material cylinder 6. After the bearing plate 71 rotates, the plastic masterbatch falls from the notch. The bearing plate 71 and the baffle cooperate to guide the plastic masterbatch. At the same time, the bearing plate 71 is impacted by the plastic masterbatch and will continuously compress the spiral spring 73, so that the bearing plate 71 rotates reciprocally, thus achieving the effect of dispersing the plastic masterbatch and uniformly adding the plastic masterbatch.

[0043] As Figure 4As shown, the left and right sides of the pressure plate 71 are provided with inclined surfaces 74, the inner wall of the barrel 6 is fixedly connected to the first spring 76, the end of the first spring 76 is fixedly connected to the inclined limit block 75, the inclined limit block 75 is located on the rotation path of the pressure plate 71, the inner wall of the barrel 6 is fixedly installed with a guide support plate 77, the corner of the inclined limit block 75 is slidably connected to the guide support plate 77, the connection between the pressure plate 71 and the coil spring 73 is fixedly installed with a support shaft 72, the support shaft 72 is rotatably connected to the barrel 6, and the guide support plate 77 supports and guides the inclined limit block 75. Two inclined limit blocks 75 are provided, and are symmetrically arranged at the barrel mouth of the barrel 6. The two inclined limit blocks 75 contact the inclined surfaces 74 on both sides of the pressure plate 71 respectively, and the inclined surface angle of the inclined surface 74 is the same as the inclined surface angle of the inclined limit block 75, and the same inclined surface angle allows for mutual extrusion.

[0044] The plastic masterbatch on the pressure plate 71 presses down the pressure plate 71, and the pressure plate 71 compresses the coil spring 73 and uses the inclined surface 74 to squeeze the inclined limit block 75. The inclined limit block 75 is forced to move away from the pressure plate 71 and compress the first spring 76. The plastic masterbatch in the barrel 6 flows normally. The gravity of the pressure plate 71 and the gravity of the plastic masterbatch thereon are greater than the resistance formed by the inclined limit block 75 and the first spring 76 and the elastic force of the coil spring 73. The pressure plate 71 rotates to the bottom of the inclined limit block 75. When the barrel 6 is at the mouth of the barrel 6, the pressure plate 71 is rotated to the bottom of the inclined limit block 75. The plastic masterbatch is blocked, and the gravity of the pressure plate 71 and the gravity of the plastic masterbatch thereon as well as the resistance formed by the inclined limit block 75 and the first spring 76 are less than the elastic force of the coil spring 73. At this time, the pressure plate 71 moves from the bottom of the inclined limit block 75 to the top of the inclined limit block 75, and the resistance force on the rotation of the pressure plate 71 is instantly reduced. The inclined limit block 75 is used to block the pressure plate 71 to accumulate force for the coil spring 73, and the pressure plate 71 quickly rotates and resets, accelerating the reset of the pressure plate 71 to cause the pressure plate 71 to vibrate.

[0045] like Figure 8 As shown, wave parts are arranged on both sides of the pressure plate 71, and the wave parts include a docking plate 78, a clearance groove 79, a push rod 710, a sliding ball 711 and a guide block 712. The docking plates 78 are fixedly installed on the left and right sides of the pressure plate 71, and a clearance groove 79 is provided on the docking plate 78. The push rod 710 passes through the docking plate 78 from the clearance groove 79. Two sliding balls 711 are fixedly installed on the rod body of the push rod 710, and the two sliding balls 711 are respectively located on the upper and lower sides of the docking plate 78. The top of the push rod 710 is fixedly installed with a guide block 712, and the side of the guide block 712 is fixedly installed with an anti-seepage blocking block 713. The anti-seepage blocking block 713 is rotatably connected to the dredging plate 714 on the side away from the wave part.

[0046] Since the rotation of the pressure plate 71 will cause the positions of the docking plate 78 and the extension rod 710 to be misaligned, the extension rod 710 slides in the clearance groove 79 to prevent the pressure plate 71 from being stuck by the extension rod 710 when rotating.

[0047] The bearing plate 71 rotates and resets quickly. Due to the inertia of the coil spring 73, the bearing plate 71 will vibrate reciprocally. At this time, the bearing plate 71 drives the sliding bead 711 to move by means of the docking plate 78. The sliding bead 711 drives the guide block 712 and the anti-seepage blocking block 713 to move reciprocally through the top extension rod 710. The anti-seepage blocking block 713 drives the dredging plate 714 on its side to move reciprocally. When the dredging plate 714 moves upward, due to the resistance of the plastic masterbatch, the dredging plate 714 is pressed against the anti-seepage blocking block 713. When the dredging plate 714 moves downward, the dredging plate 714 rotates under the resistance of the plastic masterbatch and separates from the anti-seepage blocking block 713. At this time, the dredging plate 714 pulls down the plastic masterbatch, thereby dredging the blocked plastic masterbatch.

[0048] As Figure 8 shown, the anti-seepage blocking block 713 and the dredging plate 714 are combined to form an I-shaped structure. A guide groove 715 is opened inside the barrel 6. The anti-seepage blocking block 713 slides at the guide groove 715. The up-and-down length of the anti-seepage blocking block 713 is longer than that of the guide groove 715. The anti-seepage blocking block 713 always covers the guide groove 715 during the up-and-down movement, and the dredging plate 714 contacts the plastic masterbatch, preventing the plastic masterbatch from oozing out from the guide groove 715.

[0049] In this embodiment, the plastic masterbatch inside the barrel 6 flows normally. The bearing plate 71 is pressed down by the plastic masterbatch to below the inclined limiting block 75. When the plastic masterbatch is blocked, at this time, the plastic masterbatch on the bearing plate 71 keeps falling, while the plastic masterbatch in the barrel 6 no longer falls. At this time, the bearing plate 71 moves from below the inclined limiting block 75 to above the inclined limiting block 75. The resistance force for the bearing plate 71 to rotate is instantaneously reduced. The inclined limiting block 75 is used to block the bearing plate 71 to store energy for the coil spring 73. The bearing plate 71 rotates and resets quickly, accelerating the reset of the bearing plate 71 to make the bearing plate 71 vibrate. The bearing plate 71 uses the wave member to make the dredging plate 714 move reciprocally. When the dredging plate 714 moves upward, due to the resistance of the plastic masterbatch, the dredging plate 714 is pressed against the anti-seepage blocking block 713. When the dredging plate 714 moves downward, the dredging plate 714 rotates under the resistance of the plastic masterbatch and separates from the anti-seepage blocking block 713. At this time, the dredging plate 714 pulls down the plastic masterbatch, thereby dredging the blocked plastic masterbatch.

[0050] Embodiment 2

[0051] Based on Embodiment 1, this embodiment proposes a multi-production-line feeding device for plastic products. As Figure 5As shown, a diffusion assembly 8 is provided on the inner wall at the barrel opening of the barrel 6 and below the bearing plate 71. The diffusion assembly 8 includes a central block 81, fan plates 82, torsion springs 83 and support members. The fan plates 82 are rotatably connected to the arc surface of the central block 81, and the torsion springs 83 are elastically connected between the fan plates 82 and the central block 81. A plurality of fan plates 82 are provided and are annularly and equally angularly distributed on the arc surface of the central block 81. The fan plates 82 are inclined, and there is a spacing between adjacent fan plates 82. When the bearing plate 71 moves below the inclined limit block 75, the bearing plate 71 is inclined and faces the fan plates 82.

[0052] The plastic masterbatch on the bearing plate 71 falls onto the fan plates 82. The fan plates 82 are impacted by the gravitational potential energy of the plastic masterbatch and rotate, compressing the torsion springs 83. The plastic masterbatch on the fan plates 82 continuously falls, and the plastic masterbatch on the bearing plate 71 continuously falls onto the fan plates 82, so that the fan plates 82 continuously fluctuate. And because the fan plates 82 are inclined, when the plastic masterbatch falls onto the fan plates 82, the plastic masterbatch impacts the fan plates 82 and bounces up. A plurality of fan plates 82 are all inclined and are annularly and equally angularly distributed on the arc surface of the central block 81, so that the directions in which the plastic masterbatch bounces up on each fan plate 82 are all different.

[0053] As Figure 7 As shown, a converging outlet 88 is opened at the center of the barrel opening of the barrel 6. A closing plate 86 is slidably connected below the barrel opening of the barrel 6 and directly below the converging outlet 88. Two closing plates 86 are provided and are symmetrically arranged at the converging outlet 88. The two closing plates 86 completely close the converging outlet 88. An inclined surface is opened at the top of the closing plate 86. Opening and closing rods 87 are fixedly installed on the arc surfaces of the two closing plates 86. The two opening and closing rods 87 are cross - arranged and rotatably connected to each other. The two ends of the opening and closing rods 87 are respectively located inside and outside the barrel 6.

[0054] The plastic masterbatch inside the barrel 6 accumulates, causing the plastic masterbatch at the bottom to be compacted. Since the inclined surface is opened at the top of the closing plate 86 to support the plastic masterbatch, after the closing plate 86 is removed, the plastic masterbatch at the lowest point forms a sharp corner, and there is no plastic masterbatch compaction on the left and right sides of the sharp corner. Therefore, the plastic masterbatch on the barrel 6 falls. When the plastic masterbatch falls onto the bearing plate 71, the bearing plate 71 rotates, and reciprocally rotates in cooperation with the coil spring 73, performing the steps of the first embodiment. Even when there is no blockage, the falling speed of the plastic masterbatch inside the barrel 6 onto the bearing plate 71 changes, and the balance among the gravity of the bearing plate 71, the elastic force of the coil spring 73 and the gravity of the plastic masterbatch will be broken, so that the bearing plate 71 generates reciprocating rotation.

[0055] As Figure 5As shown, the central block 81 is fixedly connected to the inner wall at the barrel mouth of the barrel 6 through a support member. The support member includes a vertical support rod 84 and a horizontal support rod 85. The two ends of the vertical support rod 84 are respectively fixedly connected to the central block 81 and the horizontal support rod 85, and both ends of the horizontal support rod 85 are fixedly connected to the barrel 6. The vertical support rod 84 and the horizontal support rod 85 support the central block 81.

[0056] In this embodiment, the plastic masterbatch on the bearing plate 71 falls onto the fan plate 82. The fan plate 82 is impacted by the gravitational potential energy of the plastic masterbatch to rotate and compress the torsion spring 83. The plastic masterbatch on the fan plate 82 continuously falls, and the plastic masterbatch on the bearing plate 71 continuously falls onto the fan plate 82, so that the fan plate 82 continuously fluctuates. And because the fan plate 82 is inclined, when the plastic masterbatch falls onto the fan plate 82, the plastic masterbatch impacts the fan plate 82 and bounces up. Multiple fan plates 82 are all inclined and annularly distributed at equal angles on the arc surface of the central block 81, so that the bouncing directions of the plastic masterbatch on each fan plate 82 are different, thereby scattering the plastic masterbatch, and using the vibration of the fan plate 82 to disperse plastic masterbatches of different sizes. During the feeding process, the plastic masterbatch can be dispersed and mixed with the color masterbatch and additives, improving the mixing efficiency.

[0057] Embodiment 3

[0058] Based on the above Embodiment 1 or 2, this embodiment proposes a feeding device for multiple production lines of plastic products, as Figure 8 and 9 shown, a vibrating component 9 is arranged inside the barrel 6 and above the anti-seepage blocking block 713. The vibrating component 9 includes a ring 92, vibrating rods 93 and a spreading sheet 95. The bottom of the ring 92 is fixedly connected to the guiding block 712, the top of the ring 92 is fixedly connected to the vibrating rods 93, the spreading sheet 95 is laid inside the barrel 6, the spreading sheet 95 adopts a funnel-shaped structure, and the spreading sheet 95 is located on the moving path of the vibrating rods 93. An annular groove 91 is formed inside the barrel 6, and the ring 92 slides up and down in the annular groove 91 and is annularly distributed at equal angles on the top of the ring 92.

[0059] The barrel 6 supports the spreading sheet 95, and the spreading sheet 95 supports the plastic masterbatch. When the plastic masterbatch inside the barrel 6 is about to be completely discharged, at this time, the amount of plastic masterbatch falling inside the barrel 6 is small, the downward pressure of the plastic masterbatch on the bearing plate 71 is reduced, and at this time, the coil spring 73 causes the bearing plate 71 to rotate counterclockwise, so that the guiding block 712 moves upward. The guiding block 712 drives the vibrating rods 93 to impact the spreading sheet 95 through the ring 92. Since the amount of plastic masterbatch inside the barrel 6 is small at this time, the pressure of the plastic masterbatch on the spreading sheet 95 is small, so the spreading sheet 95 is pushed up, and the vibrating rods 93 impact the spreading sheet 95 to cause it to vibrate, thereby vibrating off the plastic masterbatch adhering to the spreading sheet 95.

[0060] As Figure 9As shown, a vibration cavity 94 is formed inside the barrel 6. There is a gap between the barrel 6 and the spreading plate 95. The center of the bottom of the spreading plate 95 is docked with the converging outlet 88. The plastic masterbatch inside the barrel 6 is arranged above the spreading plate 95. The spreading plate 95 guides the plastic masterbatch, and the vibration cavity 94 is used for the movement of the vibrating rod 93.

[0061] In this embodiment, when the plastic masterbatch inside the barrel 6 is about to be completely discharged, the amount of the plastic masterbatch falling inside the barrel 6 is small, and the downward pressure of the plastic masterbatch on the bearing plate 71 is reduced. At this time, the guiding block 712 moves upward. The guiding block 712 drives the vibrating rod 93 to impact the spreading plate 95 by means of the circular ring 92. Since the amount of the plastic masterbatch inside the barrel 6 is small at this time, the pressure of the plastic masterbatch on the spreading plate 95 is small. Therefore, the spreading plate 95 is lifted, and the vibrating rod 93 impacts the spreading plate 95 to cause it to vibrate, thereby vibrating off the plastic masterbatch adhering to the spreading plate 95.

[0062] The above specific embodiments are merely several alternative embodiments of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
