Description

Technical Field

[0001] The invention relates to the technical field of plastic production, in particular to a feeding device for producing degradable plastics. Background Art

[0002] Degradable plastic bags are bags made of plastic as the main raw material. They are indispensable items in people's daily lives and are often used to hold other items. In the production process of degradable plastic bags, plastic particles need to be blown into the required plastic film, so plastic particles need to be added to the blow molding machine.

[0003] According to a feeding device for the production of degradable plastic bags disclosed (Announcement No.: CN221215847U), in the above application, a support ring and a support plate 1 are arranged on the outer side of the conveying screw, and the conveying screw is rotated in the support ring by the support plate 1, and the angle of the conveying screw is adjusted, so that the conveying screw can be easily adjusted in direction to convey raw materials.

[0004] However, in actual use of the above-mentioned equipment, the spiral auger needs a relatively closed environment when conveying granular plastic upwards, and also needs a relatively stable amount of conveyed material. Traditional granular plastic materials are usually fed on one side of the equipment during feeding, which easily causes the material to be unevenly distributed in the feeding chamber, with less material distributed on the side away from the feeding. As a result, the feeding process of the spiral auger cannot maintain stability and continuity, which can easily affect the subsequent production of plastic products. In view of this, we propose a feeding device for the production of degradable plastics. Summary of the invention

[0016] Compared with the prior art, the present invention provides a feeding device for the production of degradable plastics, which has the following beneficial effects:

[0017] 1. The feeding device for the production of degradable plastics is provided with a cloth assembly. Through the rotation of the auger rod, the driving gear and the driven gear are coordinated to make the turntable rotate at a speed lower than the rotation speed of the auger rod, thereby driving the three groups of outer arc plates on the upper surface of the turntable to perform circular motion on the outer surface of the feeding barrel. The setting of the wave groove and the driving of the T-shaped slider by the guide ball make the cloth plate perform a small reciprocating motion in the vertical direction with the T-shaped slider. The setting of the fitting spring and the I-shaped slider is coordinated to make the cloth plate always fit on the upper surface of the plastic particle raw material, so that the raw material distribution in the feeding chamber is more uniform, so as to ensure the stable feeding of the spiral auger, and then ensure the normal production efficiency of the degradable plastic.

[0018] 2. The feeding device for the production of biodegradable plastics is provided with a torsion component. When the cloth plate moves on the surface of the plastic particle raw material, the connecting tube itself will deflect at a certain angle. During this process, the gear rod slides in the cloth plate and cooperates with the pinion to drive the rotating rod to rotate. At this time, the notched ring arranged on the outside of the rotating rod pushes the baffle plate and then drives the torsion sleeve and the torsion plate to rotate 90°. When the cloth plate finishes shoveling and detaches from the plastic particles upward, the cloth plate drives the connecting tube to reverse. At this time, the transmission of the gear rod and the pinion causes the torsion sleeve to drive the torsion plate to reset and rotate to be parallel to the gear rod, so as to slow down the falling speed of the plastic particles at the top of the cloth plate, thereby making their distribution more dispersed, thereby ensuring the uniformity of the distribution of the plastic particle raw materials in the feeding chamber, so as to ensure the stable feeding requirements of the spiral auger.

[0019] 3. The feeding device for the production of biodegradable plastics is provided with a material dividing assembly. When the main push plate is driven by the gear rod to slide in the horizontal direction, it cooperates with the auxiliary transmission rod to move in an arc along the inner surface of the arc groove under the guidance and restriction of the rectangular groove and the arc groove, thereby driving the material dividing plate to deflect with the main transmission rod as the rotation center, and then cooperates with the torsion assembly to guide the plastic particle raw materials diverted from the surface of the cloth plate to both sides of the cloth plate, so that its diffusion range is larger.

[0020] 4. The feeding device for the production of biodegradable plastics is provided with a toggle assembly. During the rotation of the inner arc plate relative to the outer arc plate, due to the chamfered setting of the side of the inner arc plate, the inner arc plate will squeeze and push one side of the L-shaped toggle piece outward. During this process, the circular cavity surrounded by the inner arc plate and the outer arc plate has a feeding channel, which is deflected by the L-shaped toggle piece to facilitate the deposited plastic particle raw materials to smoothly enter the bottom position of the feeding barrel, so as to ensure that the bottom position of the feeding barrel is always in a state of sufficient raw materials, thereby avoiding the occurrence of cavities during the feeding process due to excessive accumulation of materials in the feeding box, thereby reducing the efficiency of upward conveying and feeding of the plastic particle raw materials.

A guiding ball 87 is fixedly installed on the outer wall of the end of the T-shaped slider 86 close to the center of the feeding box 1. A wave groove 88 is formed on the arc-shaped outer wall at the bottom end of the feeding cylinder 3. The guiding ball 87 is arranged inside the wave groove 88. A sliding rod 89 is fixedly installed on the inner wall of the T-shaped slider 86. The sliding rod 89 penetrates and is slidably installed with an I-shaped slider 810. A fitting spring 811 is fixedly connected between the side wall of the I-shaped slider 810 and the inner wall of the end of the T-shaped slider 86. A cloth plate 812 is movably installed on the outer wall of the I-shaped slider 810.

[0035] Please refer to the attached drawings of the specification Figures 1 - 2 , in an embodiment of the present invention, a feeding cavity is formed inside the feeding box 1, and the feeding cavity is in through connection with the feeding port 2, so that the staff can put granular plastic into the inside of the feeding cavity through the feeding port 2. And there is a certain gap between the bottom end of the feeding cylinder 3 and the bottom inner wall of the feeding cavity to facilitate the rotation of the outer arc plate 84 on the outer surface of the feeding cylinder 3, and at the same time, the feeding of the spiral auger 7 can be ensured. At the same time, the discharge port 4 is in through connection with the inner cavity of the feeding cylinder 3. When the driving motor 5 is started, it cooperates with the auger rod 6 and the spiral auger 7 to convey the granular plastic raw material in the feeding cavity upward, and finally discharges it outward through the discharge port 4 to facilitate plastic production. In addition, the number of the outer arc plates 84 is set to three groups, and the three groups of outer arc plates 84 are evenly distributed in a circumferential array on the top outer surface of the turntable 81.

At the same time, the arc-shaped inner surface of the turntable 81 is provided with tooth patterns that mesh with the driven gear 83, so that a planetary gear set structure is formed between the driving gear 82, the driven gear 83 and the turntable 81. When the auger rod 6 drives the driving gear 82 to rotate, the transmission of the driven gear 83 is cooperated to make the turntable 81 rotate at a speed lower than that of the auger rod 6. Specifically, there is a speed difference between the turntable 81 and the auger rod 6. Further, the guide groove 85 is arranged in an inclined shape, and the T-shaped slider 86 is movably installed inside the guide groove 85, so that the T-shaped slider 86 can only move along the inner surface of the guide groove 85, and the T-shaped slider 86 is away from the center side of the feeding box 1 The outer surface is arranged to be an arc shape matched with the inner surface of the outer arc plate 84, so that the movement of the T-shaped slider 86 on the surface of the outer arc plate 84 is smoother, so as to ensure that the cloth plate 812 can be relatively stable when the granular plastic is moved. At the same time, an I-shaped slide groove matched with the I-shaped slider 810 is provided at one end of the T-shaped slider 86 close to the cloth plate 812, so that the I-shaped slider 810 can slide inside the T-shaped slider 86. Specifically, there are two groups of fitting springs 811, and the two groups of fitting springs 811 are mirror-imaged at the left and right ends of the I-shaped slider 810. At the same time, a circular hole matched with the slide rod 89 is provided on the inner wall of the I-shaped slider 810, so as to ensure that the movement between the I-shaped slider 810 and the T-shaped slider 86 is more stable, thereby enhancing the stability of the I-shaped slider 810 and the cloth plate 812 during the movement.

[0037] During the feeding process of granular plastic, the staff continuously feeds granular plastic raw materials into the feeding port 2, and then starts the driving motor 5, cooperates with the rotation of the auger rod 6 and the spiral auger 7, so as to transport the plastic raw materials in the feeding box 1 upward, and finally discharges them outward through the outlet 4 to the material production equipment. At the same time, through the rotation of the auger rod 6, cooperates with the driving gear 82 and the driven gear 83, so that the turntable 81 rotates at a speed lower than the speed of the auger rod 6, thereby driving the three sets of outer arc plates 8 on the upper surface of the turntable 81 The outer surface of the feeding cylinder 3 performs a circular motion, and the wave groove 88 is set and the guide ball 87 drives the T-shaped slider 86, so that the distribution plate 812 performs a small reciprocating motion in the vertical direction along with the T-shaped slider 86, and the setting of the fitting spring 811 and the I-shaped slider 810 is set, so that the distribution plate 812 is always fitted on the upper surface of the plastic granule raw material, so that the raw material distribution in the feeding chamber is more uniform, so as to ensure the stable feeding of the spiral auger 7, and further ensure the normal production efficiency of the degradable plastic.

[0038] Please refer to the instruction manual Figures 8 - 11In the embodiment of the present invention, a torsion assembly 9 is provided inside the material distribution plate 812, which can prolong the buffer time of the plastic granule raw material on the material distribution plate 812 during distribution. The torsion assembly 9 includes a connecting tube 91, the end of the connecting tube 91 is rotatably mounted on the inner wall of the I-shaped slider 810, and the end of the connecting tube 91 away from the I-shaped slider 810 is fixedly connected to the side wall of the material distribution plate 812. A volute spring 92 is sleeved on the arc-shaped outer surface of the connecting tube 91, a square rod 93 is fixedly mounted on the inner wall of the I-shaped slider 810, and a transmission column 94 is slidably mounted on the outer wall of the square rod 93. A convex ball 95 is fixedly mounted on the arc-shaped inner wall of the connecting tube 91, and a spiral groove 96 is provided on the arc-shaped outer surface of the transmission column 94. The convex ball 95 is arranged inside the spiral groove 96, and a gear rod 97 is fixedly installed on the end of the transmission column 94 away from the I-shaped slider 810, a rotating rod 98 is rotatably installed on the inner wall of the cloth plate 812, and a pinion 99 is passed through and fixedly installed on the rotating rod 98. The top surface of the rotating rod 98 is rotatably connected to a torsion sleeve 910, and a torsion plate 911 is fixedly installed on the outer wall of the torsion sleeve 910. A baffle 912 is fixedly installed on the inner arc-shaped inner wall of the end of the torsion sleeve 910 close to the rotating rod 98, a limiting plate 913 is fixedly installed on the arc-shaped outer wall of the rotating rod 98, a notch ring 914 is fixedly installed on the arc-shaped outer wall of the rotating rod 98, and an elastic sheet 915 is fixedly connected between the side wall of the notch ring 914 and the side wall of the baffle 912.

[0039] Specifically, a rotation cavity adapted to the connecting cylinder 91 is provided on the inner wall of the I-shaped slider 810, and the two ends of the volute spring 92 are respectively fixedly connected to the bottom inner wall of the rotation cavity and the arc-shaped outer wall of the connecting cylinder 91, so that the connecting cylinder 91 always has a movement tendency of reverse rotation to achieve reset when rotating. At the same time, the outer diameter of the transmission column 94 is adapted to the size of the internal cavity of the connecting cylinder 91, so that the connecting cylinder 91 and the transmission column 94 can move relative to each other without the problem of motion interference. Further, the transmission column 94 is close to the I-shaped slider 810. A square hole is formed on the inner wall of one end thereof to match the square rod 93, thereby limiting the transmission column 94 to linear motion only in the horizontal direction. At the same time, during the rotation of the connecting tube 91, the transmission column 94 is guided and restricted by the convex ball 95 and the spiral groove 96, so that the transmission column 94 moves in the horizontal direction along the outer surface of the square rod 93. Under the influence of the elastic force of the volute spring 92, the connecting tube 91 will prompt the transmission column 94 to perform a horizontal reset movement on the outer surface of the square rod 93 when resetting, and finally drive the gear rod 97 to slide left and right in the horizontal direction.

[0040] In addition, the pinion gear 99 meshes with the rack 97 to achieve transmission. A rotation hole adapted to the size of the torsion sleeve 910 is provided on the inner wall of the top of the cloth distributing plate 812, and the bottom end of the torsion sleeve 910 is rotatably installed inside the rotation hole. At the same time, a circular groove with a diameter larger than the outer diameter of the notch ring 914 is provided on the inner wall of one end of the torsion sleeve 910 close to the rotating rod 98, and the top end of the rotating rod 98 is rotatably connected to the inner wall of the top of the circular groove. At the same time, the baffle 912, the limiting plate 913, the notch ring 914 and the elastic piece 915 are all arranged in the same plane, and the baffle 912 and the limiting plate 913 are arranged correspondingly. The thickness of the baffle 912 is smaller than the thickness of the notch ring 914. At the same time, the surface of the limiting plate 913 close to the rotating rod 98 is attached to the arc-shaped outer wall of the rotating rod 98, so that when the rotating rod 98 remains stationary, the torsion sleeve 910 can only rotate away from the limiting plate 913 on the top of the rotating rod 98. Further, the notch of the notch ring 914 is set to 90°, so that the torsion sleeve 910 can drive the torsion plate 911 to rotate at most 90° even when rotating. And through the setting of the elastic piece 915, the torsion sleeve 910 always has a movement tendency of reverse rotation to achieve reset.

[0041] When the cloth distributing plate 812 distributes on the surface of the plastic particle raw material, especially when the cloth distributing plate 812 is pressed down and inserted into the plastic particle raw material on the surface layer, due to the influence of its resistance, the connecting cylinder 91 itself will deflect at a certain angle. In this process, through the relative rotation between the connecting cylinder 91 and the transmission column 94, and the guidance and limitation of the convex ball 95 and the spiral groove 96, the transmission column 94 moves horizontally away from the outer arc plate 84 along the outer surface of the square rod 93, thereby pushing the rack 97 to slide, and driving the rotating rod 98 to rotate through the pinion gear 99. At this time, the notch ring 914 arranged outside the rotating rod 98 pushes the baffle 912, thereby driving the torsion sleeve 910 and the torsion plate 911 to rotate 90°. When the cloth distributing plate 812 finishes shoveling the material and moves upward away from the plastic particles, the cloth distributing plate 812 drives the connecting cylinder 91 to reverse. At this time, through the transmission of the rack 97 and the pinion gear 99, the torsion sleeve 910 drives the torsion plate 911 to rotate back to be parallel to the rack 97, so as to delay the falling speed of the plastic particles at the top position of the cloth distributing plate 812, and further make its distribution more dispersed, so as to ensure the uniformity of the distribution of the plastic particle raw material in the feeding cavity, so as to ensure the stable feeding requirement of the spiral auger 7.

[0042] Please refer to the attached instructions Figure 6 and Figure 8, in an embodiment of the present invention, a material distribution component 10 is provided inside the cloth plate 812 to promote the uniform dispersion of the plastic particle raw materials on the surface of the cloth plate 812. The material distribution component 10 includes a connecting rod 101, the top end of the connecting rod 101 is fixedly connected to the side wall of the toothed rod 97, the bottom end of the connecting rod 101 is fixedly connected with a main pushing plate 102, a notch groove is opened at the bottom end of the cloth plate 812, a main transmission rod 103 is fixedly installed on the inner wall at the bottom end of the notch groove, a material distribution plate 104 is rotatably connected to the end of the main transmission rod 103, a secondary transmission rod 105 is rotatably installed on the inner wall of one end of the material distribution plate 104 close to the cloth plate 812, an arc groove 106 is opened on the inner wall of one side of the cloth plate 812 close to the notch groove, the secondary transmission rod 105 is arranged in the arc groove 106, a transmission gear 107 is rotatably installed on the inner wall of the cloth plate 812, and a secondary pushing plate 108 is slidably installed on the inner wall of the cloth plate 812.

[0043] Specifically, a transmission cavity is opened on the inner wall of the cloth plate 812 for the connecting rod 101, the main pushing plate 102 and the secondary pushing plate 108 to perform small horizontal movements, so that when the toothed rod 97 slides horizontally inside the cloth plate 812, there will be no problem of movement interference. At the same time, the number of notch grooves is multiple, and the multiple notch grooves are evenly distributed in a linear array on the outer wall of the end of the cloth plate 812. At the same time, the main transmission rod 103 and the material distribution plate 104 are arranged at the vertical central axis of the notch groove. Further, a rectangular groove with a width adapted to the outer diameter of the secondary transmission rod 105 is opened on the inner wall of the main pushing plate 102. When the main pushing plate 102 is driven by the connecting rod 101 to slide horizontally, under the guidance and restriction of the rectangular groove and the arc groove 106, the secondary transmission rod 105 is driven to move along the inner surface of the arc groove 106 in an arc, thereby driving the material distribution plate 104 to deflect with the main transmission rod 103 as the rotation center, and then cooperating with the twisting component 9 to guide the plastic particle raw materials shunted on the surface of the cloth plate 812 to both sides of the cloth plate 812, so that its diffusion range is larger.

[0044] At the same time, the main pushing plate 102 and the secondary pushing plate 108 are symmetrically arranged on the left and right sides of the vertical central axis of the cloth plate 812, and the central symmetry point of the main pushing plate 102 and the secondary pushing plate 108 is the axis center of the transmission gear 107. In addition, racks that can be engaged with the transmission gear 107 and realize transmission are arranged at one end of the main pushing plate 102 and the secondary pushing plate 108 close to the transmission gear 107. Then, with the cooperation of the transmission gear 107, the main pushing plate 102 and the secondary pushing plate 108 can move synchronously towards or away from each other, and then guide the material distribution plate 104 to be arranged in a "V" shape at the bottom end of the cloth plate 812, promoting the plastic particle raw materials to move towards the center of the feeding cavity and away from the center of the feeding cavity, improving the distribution uniformity of the plastic particle raw materials in the feeding cavity, and then ensuring the normal production requirements of the spiral auger 7.

[0045] Please refer to the instruction manual Figures 3 - 5 In the embodiment of the present invention, a toggle assembly 11 for stabilizing the feeding inside the bottom end of the loading barrel 3 is provided on the top of the turntable 81. The toggle assembly 11 includes a disc 111, which is rotatably mounted on the upper surface of the turntable 81. The disc 111 penetrates and is fixedly connected to the auger rod 6. An inner arc plate 112 is fixedly mounted on the upper surface of the disc 111. Swinging cavities are provided on the inner walls of both sides of the inner arc plate 112. A round rod 113 is rotatably mounted on the inner wall of the swinging cavity. An L-shaped toggle piece 114 is penetrated and fixedly mounted on the round rod 113. A coil spring 115 is sleeved on the arc-shaped outer wall of the round rod 113. A tooth groove 116 is provided on the inner wall of one side of the L-shaped toggle piece 114.

[0046] In an embodiment of the present invention, the arc shape of the inner arc plate 112 is adapted to the outer arc plate 84, and the arc outer surface of the inner arc plate 112 is fitted with the arc inner surface of the outer arc plate 84, so that the two can not interfere with each other during the rotation process, and at the same time, the gap between the two can be kept small enough, and the granular plastic raw material will not enter therein. At the same time, the arc outer wall at one end of the inner arc plate 112 is chamfered to avoid the L-shaped shifter 114 from getting stuck during the relative rotation between the inner arc plate 112 and the outer arc plate 84. In addition, cylindrical cavities with a diameter larger than the coil spring 115 are provided on the inner walls at the upper and lower ends of the swing cavity, and the two ends of the coil spring 115 are fixedly connected to the bottom inner wall of the cylindrical cavity and the arc outer wall of the round rod 113, respectively, so that the round rod 113 always has a movement tendency of reverse rotation to achieve reset when rotating.

[0047] At the same time, the number of tooth grooves 116 is set in multiple groups, and the multiple groups of tooth grooves 116 are evenly distributed in a linear array on the inner wall of the L-shaped shifter 114 away from the center of the loading box 1. During the rotation of the auger rod 6, due to the setting of the driving gear 82 and the driven gear 83, there is a speed difference between the turntable 81 and the disc 111, that is, there is a speed difference between the inner arc plate 112 and the outer arc plate 84. During the rotation of the inner arc plate 112 relative to the outer arc plate 84, due to the chamfer setting of the side of the inner arc plate 112, the inner arc plate 112 will squeeze and push one side of the L-shaped shifter 114 outward. In this process, the circular ring surrounded by the inner arc plate 112 and the outer arc plate 84 The cavity has a feeding channel, through the deflection of the L-shaped puller 114, so as to facilitate the deposited plastic granule raw materials to smoothly enter the bottom position of the loading barrel 3, and then the feeding work is carried out through the spiral auger 7 until the inner arc plate 112 is no longer in contact with the L-shaped puller 114. At this time, the feeding channel between the inner arc plate 112 and the outer arc plate 84 becomes smaller. At this time, the L-shaped puller 114 is reset under the action of the coil spring 115, and the plastic granule raw materials are reset again to ensure that the bottom position in the loading barrel 3 is always in a state of sufficient raw materials, avoiding the occurrence of cavities during the loading process due to excessive accumulation of materials in the loading box 1, thereby reducing the efficiency of the upward conveying and loading of the plastic granule raw materials.

[0048] In the present invention, when in use, the staff continuously feeds granular plastic raw materials into the feeding port 2 to gradually fill the feeding chamber until the granular plastic raw materials cover the inner arc plate 112. At this time, the driving motor 5 is started to cooperate with the rotation of the auger rod 6 and the spiral auger 7 to transport the plastic raw materials in the feeding box 1 upward, and finally discharge them outward through the outlet 4 to the material production equipment. At the same time, through the rotation of the auger rod 6, the driving gear 82 and the driven gear 83 are cooperated to make the turntable 81 rotate at a speed lower than the speed of the auger rod 6, thereby driving the rotary table 81 to rotate. The three groups of outer arc plates 84 on the upper surface of the disk 81 perform circular motion on the outer surface of the loading barrel 3, and cooperate with the setting of the wave groove 88 and the driving of the T-shaped slider 86 by the guide ball 87, so that the cloth plate 812 performs a small reciprocating motion in the vertical direction with the T-shaped slider 86, and cooperates with the setting of the fitting spring 811 and the I-shaped slider 810, so that the cloth plate 812 is always in contact with the upper surface of the plastic particle raw material, so that the raw material distribution in the loading chamber is more even, so as to ensure the stable loading of the spiral auger 7, and then ensure the normal production efficiency of the degradable plastic.

[0049] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
