Description

Technical Field

[0001] The invention relates to the technical field of plastic product production, in particular to an automatic material suction mechanism for environmentally friendly plastic particle raw materials. Background Art

[0002] Environmentally friendly plastic particles refer to plastic particles with environmentally friendly characteristics. Most of them are made of recycled materials or adopt specific production processes to reduce the impact on the environment, so that they can gradually decompose in the natural environment and reduce damage to the ecosystem. As people's environmental awareness increases, more and more fields are beginning to use environmentally friendly plastic particles as raw materials to promote sustainable development and reduce environmental pollution.

[0003] In the prior art, when producing with plastic particles, most of the time, the plastic particles are piled inside a box and then pumped and fed by a suction mechanism, or the suction is directly performed in a bag containing the plastic particles, so that the plastic particles can be transported normally. However, due to the level of production and the limitation of production space, there will be more or less small particles of impurities and dust in the environmentally friendly plastic particle raw materials. If they are to be discharged, a cleaning process needs to be added, which reduces the actual production efficiency. At the same time, after pumping and feeding, the plastic particles are not directly discharged for use, but are piled in a container for preparation. Since the entry direction is fixed, the plastic particles will inevitably form a slope when they are piled in the container, affecting the detection accuracy of the sensor. Based on this, the present invention provides an automatic suction mechanism for environmentally friendly plastic particle raw materials to solve the above problems. Summary of the invention

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 6 The present invention provides a technical solution: an automatic material suction mechanism for environmentally friendly plastic granule raw materials, comprising a fixed frame 1 and a feeding box 8, a material storage tank 2 is fixed on the inner side of the fixed frame 1, a vacuum pump 3 is fixedly installed on the top of the fixed frame 1, an air extraction pipe 4 that penetrates the outer side of the material storage tank 2 and extends to the inside thereof is fixedly installed on the input end of the vacuum pump 3, a balancing valve 5 that is connected to the inside of the material storage tank 2 is fixedly installed on the top, a material sensing sensor 6 is fixedly installed on the inner left wall of the material storage tank 2, a flattening component 700 for pushing the raw materials to make them flat is installed on the inner side of the material storage tank 2, and a conveying component 900 for conveying the raw materials is installed on the inner side of the feeding box 8;

[0030] In the above-mentioned embodiment, through the cooperation between the material storage tank 2, the vacuum pump 3, the exhaust pipe 4, the material sensing sensor 6 and the horizontal component 700, the kinetic energy of the incoming raw materials can be recovered and used to drive the horizontal component 700 to transmit, so that it can stir the raw materials, thereby avoiding the situation where the height of one side is higher and the other side is lower when feeding on one side, so that the material sensing sensor 6 can sense the height of the raw materials more accurately, which is convenient for controlling the amount of raw materials. Through the coordinated use of the loading box 8 and the conveying component 900, the incoming raw materials can be conveyed, and the internal impurities and dust can be effectively discharged during the conveying process, which is convenient for subsequent production work, and can also avoid the situation where the raw materials are easily dusted when they are accumulated inside the box with a larger opening.

[0031] In this embodiment, the conveying assembly 900 is a structure used to temporarily store raw materials and can remove impurities and dust from them.

[0033] It should be noted that a removal hole for removing the collection box 903 is provided on the back of the loading box 8, which facilitates the removal of the collection box 903 from the interior of the loading box 8. The right end of the conveying rod 906 passes through the inner box 902 and the loading box 8 in sequence and extends to the outside. The left end of the air inlet pipe 913 passes through the right end of the conveying rod 906 and is rotatably connected to the inner side of the conveying rod 906 through a bearing, so that the air inlet pipe 913 can transfer the airflow output by the air delivery fan 912 to the interior of the conveying rod 906, wherein the input end of the air delivery fan 912 is detachably connected to a dust filter.

[0034] In addition, the inner bottom wall of the inner box 902 is inclined toward the side close to the bottom end of the suction tube 914, and the height of the arc-shaped blade 908 decreases from left to right, so that the arc-shaped blade 908 can match the inner bottom wall of the inner box 902, allowing the arc-shaped blade 908 to turn over the raw materials inside the inner box 902, and the output shaft of the servo motor 910 passes through the loading box 8 and the inner box 902 and is fixedly connected to the left end of the conveying rod 906, so that the servo motor 910 can drive the conveying rod 906 to rotate.

[0035] At the same time, the top of the dust exhaust fan 916 is the output surface, and the end of the dust exhaust pipe 918 is fixedly connected to the input end of the bag dust collector 917, so that the dust exhaust fan 916 can draw the dust inside the feeding box 8 and convey it through the dust exhaust pipe 918 to the inside of the bag dust collector 917 for processing, wherein the bag dust collector 917 is composed of an outer shell, a bag filter and an air outlet. By conveying dust-laden air to the interior of the bag filter, the dust can remain in the bag filter, and the air is discharged normally through the air outlet to achieve the filtering effect. It is an existing bag dust removal equipment, so it will not be described in detail.

[0036] In this embodiment, the flattening component 700 is a structure for recycling kinetic energy so that it can be used to smooth the raw materials.

[0037] like Figure 2 , Figure 3 and Figure 4As shown, the horizontal assembly 700 includes an inclined panel 701 fixed to the left inner wall of the storage tank 2, a support plate 702 is fixed to the inner side of the storage tank 2, a connecting rod 703 is rotatably connected to the bottom of the support plate 702 through a bearing, a plurality of smoothing rods 704 are fixed to the outer side of the connecting rod 703, a discharge pipe 705 connected to the interior of the storage tank 2 is fixed to the bottom, a control valve 706 connected to the interior of the discharge pipe 705 is fixedly installed, a fixing ring 707 is fixed to the outer side of the connecting rod 703, a plurality of supporting wheels 708 are fixedly installed at the bottom of the fixing ring 707, an annular slide groove 709 for the supporting wheel 708 to slide is provided on the top of the support plate 702, and a top end of the connecting rod 703 is fixed to the bottom of the connecting rod 703. A driven bevel gear 710 is fixedly installed, and a linkage rod 711 is rotatably connected between the front and rear inner walls of the storage tank 2 through a bearing. A driving bevel gear 712 is fixedly installed on the outer side of the linkage rod 711, and a support cylinder 713 is slidably connected to the outer side of the linkage rod 711. A plurality of top rods 714 fixedly connected to the bottom of the inclined plate 701 are fixed on the top of the support cylinder 713, and a sub-gear 715 is fixedly installed on the outer side of the linkage rod 711. An active rod 716 is rotatably connected to the inner side of the storage tank 2 through a bearing, a hollow fixed cylinder 717 is fixed on the outer side of the active rod 716, and a plurality of rectangular plates 718 are fixed on the outer side of the hollow fixed cylinder 717, and a main gear 719 is fixedly installed on the outer side of the active rod 716.

[0038] It should be noted that the inclined plate 701 is inclinedly arranged on the inner side of the storage tank 2, with the right side as the high point and the left side as the low point. The outer side of the exhaust pipe 4 is fixedly connected to the outer side of the storage tank 2, and the right end of the exhaust pipe 4 extends to the left side of the inclined plate 701, so that the inclined plate 701 can restrict the pumping airflow to a certain extent, so that the raw materials entering the storage tank 2 are not easily moved with the airflow. The top end of the connecting rod 703 passes through the top of the support plate 702, and the bottom of the support wheel 708 is in contact with the inner bottom wall of the annular groove 709. Specifically, the rotation direction of the support wheel 708 is the same as the circumferential direction of the annular groove 709, so that the support wheel 708 cooperates with the fixing ring 707 to play an auxiliary supporting role for the connecting rod 703, so that the connecting rod 703 can rotate more smoothly.

[0039] In addition, the outer side of the driven bevel gear 710 and the outer side of the active bevel gear 712 are meshed with each other, and the outer side of the linkage rod 711 and the inner side of the support tube 713 are both smooth, so that the support tube 713 can stably support the linkage rod 711 under the fixing action of the top rod 714, so that it can stably transmit the power, and the back ends of the linkage rod 711 and the active rod 716 both penetrate the back of the storage tank 2 and extend to the outside world. The diameter of the main gear 719 is larger than the diameter of the sub-gear 715, and the outer side of the main gear 719 and the outer side of the sub-gear 715 are meshed with each other, so that the main gear 719 can drive the sub-gear 715 to rotate.

[0040] At the same time, the end of the suction pipe 914 away from the inner box 902 passes through the loading box 8 and the storage tank 2 in sequence and extends to the interior of the storage tank 2, and the bottom end of the suction pipe 914 is bent downward, and the end of the suction pipe 914 located inside the storage tank 2 is above the rightmost rectangular plate 718. Specifically, the rectangular plate 718 will not contact the end of the suction pipe 914 during the rotation, so that the raw material discharged from the suction pipe 914 can push the right side of the rightmost rectangular plate 718 to move, and then can apply initial kinetic energy to the hollow fixed cylinder 717 and the active rod 716, so as to facilitate the recycling of the falling kinetic energy, and can properly smooth the raw materials stacked inside the storage tank 2 without applying other power equipment, so as to facilitate the material sensing sensor 6 to sense the top, and the material sensing sensor 6 can be an infrared sensor.

[0041] The working principle of the above embodiment is:

[0042] (1) When sucking the environmentally friendly plastic granule raw material, the raw material is poured into the interior of the feeding box 8 through the feed hopper 901, and the servo motor 910 is started to drive the conveying rod 906 to rotate, thereby driving the spiral blade 907 to rotate. Under the rotation and pushing action of the spiral blade 907, the raw material inside the feeding box 8 can be pushed to the side close to the suction pipe 914. During the conveying process, the arc blade 908 can turn the raw material over, so that the impurities inside can easily fall, and then pass through the sieve plate 905 into the collection box 903. The raw materials are stored in the bag filter 917, and the air is started to flow into the conveying rod 906 through the air inlet pipe 913 and then discharged through the air hole 909, so that the raw materials can be blown by other airflow during the process of being turned by the arc blades 908, so that the dust inside can fly out, and the dust exhaust fan 916 is started to transport the flying dust through the corresponding dust exhaust box 915 and the dust exhaust pipe 918 to the bag filter 917 for treatment and then discharge, so that the dust and impurities in the raw materials can be separated to a certain extent during the transportation process.

[0043] (2) When sucking materials, start the vacuum pump 3 so that it can evacuate the inside of the storage tank 2 through the suction pipe 4, thereby forming a negative pressure inside the storage tank 2, so that the suction pipe 914 can extract the raw materials inside the loading box 8 and convey them to the inside of the storage tank 2. When the raw materials are discharged through the suction pipe 914, they will push the rectangular plate 718 to move, thereby driving the hollow fixed cylinder 717 to rotate, and the active rod 716 to rotate, so that the main gear 719 rotates and drives the secondary gear 715 to rotate, so that the linkage rod 711 rotates and drives the The active bevel gear 712 rotates, and the driven bevel gear 710 is driven to rotate under the action of meshing transmission, so that the connecting rod 703 can rotate stably under the support of the fixing ring 707 and the supporting wheel 708, and then can drive the smoothing rod 704 to rotate to properly push the raw materials inside the storage tank 2, and try to avoid the occurrence of one side being too high, so as to facilitate the material sensing sensor 6 to sense the material height. When needed, open the control valve 706 to allow the material inside the storage tank 2 to continue to be transported through the discharge pipe 705.

[0044] Compared with the prior art, the automatic suction mechanism for environmentally friendly plastic granule raw materials can recover the kinetic energy of the incoming raw materials through the cooperation between the material storage tank 2, the vacuum pump 3, the exhaust pipe 4, the material sensing sensor 6 and the horizontal component 700, and is used to drive the horizontal component 700 to transmit, so that it can stir the raw materials, thereby avoiding the situation where one side is higher and the other side is lower when feeding on one side, so that the material sensing sensor 6 can sense the height of the raw materials more accurately, which is convenient for controlling the amount of raw materials. Through the coordinated use between the feeding box 8 and the conveying component 900, the incoming raw materials can be conveyed, and the internal impurities and dust can be effectively discharged during the conveying process, which is convenient for subsequent production work. It can also avoid the situation where the raw materials are easily dusted on the surface when they are accumulated inside a box with a large opening, thereby enabling it to meet the requirements for temporary storage of environmentally friendly plastic granule raw materials, and is convenient for users to use, and solves the problem that the existing automatic suction mechanism is prone to sucking in impurities and dust during the process of pumping plastic granule feeding, resulting in the actual quality of the finished product being affected.
