Description

Technical Field

[0001] The present invention relates to the technical field of negative pressure generating devices, and particularly to a negative pressure device for the silicone material feeding port in the processing of aviation inner linings. Background Art

[0002] An aviation inner lining is a material used to protect the items inside a box, mainly applied in air transportation. It has excellent flame retardant performance and high impact resistance. It usually has a phenolic resin as the matrix and a fiberglass fabric as the reinforcing material, with a white or beige decorative film adhered to the surface. The main function of the aviation inner lining is to reduce the impact on items during transportation and protect the items from damage.

[0003] The commonly used material for aviation inner linings is usually made of phenolic resin and fiberglass fabric, with a white or beige decorative film adhered to the surface. This material has excellent flame retardant performance and high impact resistance, and can adapt to various transportation environments. And silicone materials are used in the production process of fiberglass fabrics. Therefore, during the processing of fiberglass fabrics, silicone is sent into the designated processing equipment through a silicone material feeding device.

[0004] In the prior art, however, the silicone material feeding device generally transports the silicone material through a pipeline, and dust particles are generally doped in the silicone material. As a result, when the silicone material is discharged from the material feeding port of the feeding device, the dust will disperse everywhere, causing pollution to the workshop. At the same time, the dust mixed into the processing equipment will affect the quality of the processed fiberglass fabric. Summary of the Invention

[0005] The purpose of the present invention is to provide a negative pressure device for the silicone material feeding port in the processing of aviation inner linings to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A negative pressure device for the silicone material feeding port in the processing of aviation inner linings, comprising: a material feeding pipe; a plurality of first negative pressure pipes are communicated with the outer side wall of the material feeding pipe, a first partition component is connected between the inner side walls of the material feeding pipe, a first auxiliary material feeding component is connected in the material feeding pipe, both the first auxiliary material feeding component and the first negative pressure pipes are located above the first partition component, a lifting component is arranged in the material feeding pipe, and the lifting component is connected to the first partition component to open or close the first partition component;

[0007] The first auxiliary material feeding component includes a fixing plate connected between the inner walls of the material feeding pipe, a plurality of swinging mechanisms are annularly and equally angularly connected to the bottom of the fixing plate, and a plurality of pairs of material receiving plates are annularly and equally angularly connected to the plurality of swinging mechanisms. Each pair of the two material receiving plates is distributed in an isosceles triangle shape with the tip part aligned with the axis of the fixing plate.

[0008] Preferably, the first partition assembly includes a first fixed ring fixedly connected between the inner side walls of the discharge tube, a first inverted truncated cone-shaped blanking cavity is opened on the top of the first fixed ring, a first discharge cavity is connected to the inner bottom wall of the first blanking cavity, the inner bottom wall of the first discharge cavity passes through the bottom wall of the first fixed ring, the first partition assembly also includes a first inverted truncated cone-shaped cover plate that can cover the top of the first discharge cavity, the outer side surface of the first cover plate can be tightly against the top of the first discharge cavity, and the first cover plate is connected to the lifting assembly. The advantage of such an arrangement is that the first cover plate can be driven up and down by the lifting assembly to separate the first cover plate from the top of the first discharge cavity to release the partition or make the outer side surface of the first cover plate tightly against the top of the first discharge cavity to form a partition to prevent the silicone material from falling through the first discharge cavity.

[0009] Preferably, the inclination of the outer side surface of the first cover plate is smaller than the inclination of the inner side wall of the first blanking cavity, and the angle between the inclination surfaces of the two is not less than twenty degrees. There is a line contact between the outer side surface of the first cover plate and the top of the first discharge cavity. The advantage of such a configuration is that the angle between the inclination surface of the outer side surface of the first cover plate and the inclination surface of the inner side wall of the first blanking cavity is not less than twenty degrees, thereby ensuring that the silicone material can smoothly pass through the first discharge cavity after the first cover plate is separated upward from the top of the first discharge cavity. In addition, there is a line contact between the outer side surface of the first cover plate and the top of the first discharge cavity, thereby preventing the silicone material from being crushed when the outer side surface of the first cover plate is tightly against the top of the first discharge cavity, thereby reducing damage to the silicone material and improving the reliability and practicality of the negative pressure device.

[0010] Preferably, the swing mechanism includes a plurality of rotating seats fixedly connected to the bottom of the fixed plate in an annular shape with equal angles, the bottoms of the plurality of rotating seats are hinged with a plurality of hinge plates in an annular shape with equal angles, the sides of the plurality of hinge plates away from the axial line of the fixed plate and the diameter of the bottom surface of the fixed plate are hinged with a plurality of first electric push rods in annular shape with equal angles, and the plurality of pairs of the holding plates are connected to the bottom surfaces of the plurality of hinge plates in annular shape with equal angles. The advantage of such an arrangement is that the hinge plate and the plurality of pairs of holding plates can be driven to swing up and down by the extension and contraction of the first electric push rod, thereby completing the upward shifting of the organic silicon material, which can not only prevent the organic silicon material from being blocked in the gap between the first cover plate and the top of the first discharge chamber, making the unloading process of the organic silicon material smoother, but also can make the dust mixed in the organic silicon material be more smoothly sucked away by the first negative pressure pipe when the organic silicon material slides down from the holding plate, thereby improving the dust removal effect on the organic silicon material and preventing the dust from floating around after the organic silicon material is discharged from the bottom end of the unloading pipe.

[0011] Preferably, two first motors are symmetrically fixedly connected in the plurality of hinged plates, and the output ends of the two first motors pass through the bottom wall of the hinged plate and are symmetrically fixedly connected to the two first rotating shafts, each pair of the two material holding plates are symmetrically fixedly sleeved on the outer circumferential surface of the two first rotating shafts, and each pair of the two material holding plates are symmetrically connected to two groups of material guide plates on the side surfaces facing the inner wall of the discharge tube, and each group of multiple material guide plates are equidistantly distributed along the length direction of the material holding plates, and the material guide plates and the material holding plates are not parallel in width direction. The advantage of such an arrangement is that when the two first motors are started, the two material holding plates are driven to rotate in opposite directions through the two first rotating shafts during the upward swinging process, so that the silicone material initially lifted up by the two material holding plates will slide downward along each pair of the two material holding plates as the material holding plates rotate, thereby ensuring that the silicone material slides downward more smoothly and more dispersedly, so that the first negative pressure tube can more fully and effectively absorb dust mixed in the silicone material.

[0012] Preferably, an auxiliary material-pickling assembly is connected to the inside of the feed tube, and the auxiliary material-pickling assembly is used to enable the material-holding plate that is swung to a high position to be more smoothly inserted into the bottom of the silicone material again. The advantage of such a setting is that the first auxiliary feed-pickling assembly can more smoothly perform repeated upwards movement of the silicone material on the upper side of the first cover plate, thereby further improving the effect of adsorbing and removing dust in the silicone material.

[0013] Preferably, the auxiliary material pushing component includes a fixed block fixedly connected to the top of the first cover plate. A straight hole is formed in the top of the fixed block, and the bottom end of the straight hole penetrates through the bottom of the fixed block. A plurality of partition grooves are annularly formed at equal angles on the top of the fixed block. A plurality of pairs of partition plates are rotatably connected in an annular and equiangular manner through first rotating rods on the inner bottom walls of the plurality of partition grooves. Two groups of first elastic members are symmetrically and fixedly connected between the side surfaces of each pair of partition plates close to the partition grooves and the inner side walls of the partition grooves. The fixing plate is connected to the lifting component. The lifting component can first pull the fixing plate upward and then pull the first cover plate upward. The advantage of such a setting is that while the material receiving plate pushes the silicone material on the top of the first cover plate upward, the lifting component can first pull the material receiving plate upward to the upper side of the fixed block, and then as the swinging mechanism drives the material receiving plate to rotate towards the direction close to the fixed block to the vertical position, the lifting component can drive the material receiving plate to move downward and insert it into the partition groove. In this way, due to the blocking of the partition plates, the silicone material can be prevented from entering the partition groove, so that the material receiving plate can be smoothly inserted into the bottom of the silicone material, thereby providing favorable conditions for the next upward pushing of the silicone material. In addition, when the material receiving plate needs to push the silicone material upward, the swinging mechanism is started to drive the material receiving plate to swing upward. When the material receiving plate touches the partition plate, it will overcome the elastic force of the first elastic member and push open the partition plate to continue swinging upward to push up the silicone material. When the material receiving plate separates from the partition plate, the partition plate will close again under the elastic force of the first elastic member to prevent the silicone material from entering the partition groove, so as to ensure that the material receiving plate can be smoothly inserted into the partition groove and be prepared for the next upward pushing of the silicone material.

[0014] Preferably, the lifting component includes a connecting block fixedly connected between the inner side walls of the feeding pipe through a cross bar. A second electric push rod is fixedly connected to the bottom of the connecting block, and the output end of the second electric push rod is fixedly connected to the top of the fixing plate. The lifting component further includes a first telescopic rod fixedly connected between the bottom of the fixing plate and the top surface of the first cover plate. The first telescopic rod is located in the straight hole of the fixed block. The advantage of such a setting is that when the second electric push rod contracts, under the action of the first telescopic rod, the fixing plate will be driven to move upward first. When the first telescopic rod extends to the longest position, the first cover plate will be pulled upward to release the blocking effect of the first partition component. In this way, when feeding is not required, the second electric push rod can be used to drive only the material receiving plate to move up and down reciprocally to repeatedly push the silicone material on the upper side of the first cover plate, so as to effectively adsorb and remove the dust in the silicone material, and further more effectively prevent a large amount of dust from floating around when the silicone material is discharged from the bottom end of the feeding pipe.

[0015] Preferably, a second partition assembly is connected between the inner walls of the feeding tube, and a plurality of second negative pressure tubes are connected to the outer wall of the feeding tube, the second negative pressure tube is located between the first partition assembly and the second partition assembly, the second partition assembly includes a second fixing ring fixedly connected between the inner walls of the feeding tube, a second inverted truncated cone-shaped feeding cavity is provided on the top of the second fixing ring, a second discharging cavity is connected to the inner bottom wall of the second feeding cavity, the inner bottom wall of the second discharging cavity passes through the bottom wall of the second fixing ring, the second partition assembly also includes a second inverted truncated cone-shaped cover plate which can cover the top end of the second discharging cavity, the outer side surface of the second cover plate can be tightly against the top end of the second discharging cavity, and the bottom of the first cover plate A second auxiliary unloading component is connected, and the second auxiliary unloading component is located on the upper side of the second cover plate. A second telescopic rod is fixedly connected between the second auxiliary unloading component and the top surface of the second cover plate. The second auxiliary unloading component can cooperate with the second negative pressure tube to more thoroughly adsorb and remove dust in the silicone material. The advantage of this arrangement is that the second cover plate can be pulled upward and away from the top of the second discharge chamber by the first cover plate and the second telescopic rod, so that the partition effect of the second partition component can be released to allow the silicone material to pass through the second discharge chamber and be discharged from the bottom of the unloading tube. At the same time, the second auxiliary unloading component can move the fallen silicone material to enhance the adsorption effect of the second negative pressure tube on the dust mixed in the silicone material.

[0016] Preferably, the second auxiliary blanking component includes a mounting block fixedly connected to the bottom of the first cover plate. A second motor is fixedly connected inside the mounting block. The output end of the second motor penetrates the bottom wall of the mounting block and is fixedly connected to a fixed column. A plurality of first baffle plates are fixedly connected to the outer peripheral surface of the fixed column at equal angles in a circular shape. A plurality of moving grooves are opened on the outer peripheral surface of the fixed column at equal angles in a circular shape. The plurality of moving grooves and the plurality of first baffle plates are distributed in a staggered manner. A square rod is fixedly connected between the inner top wall and the inner bottom wall of the moving groove. A plurality of second baffle plates are movably sleeved on the outer peripheral surfaces of the plurality of square rods at equal angles in a circular shape. A second elastic member is fixedly connected between the bottom of the second baffle plate and the inner bottom wall of the moving groove. The top surface of the second baffle plate is located above the top surface of the first baffle plate. The advantage of such a setting is that when the second motor drives the fixed column to rotate self - sufficiently, the fixed column will drive the plurality of first baffle plates and the plurality of second baffle plates to rotate to stir the falling silicone material. In this way, the dust mixed in the silicone material can be better separated from the silicone material. In this way, the second negative pressure pipe can more smoothly adsorb the dust. At the same time, after the fixed column drives the second telescopic rod to extend to the longest position, it will continue to pull the second cover plate upward to separate from the top end of the second discharge cavity. In this way, the partition function of the second partition component can be released so that the silicone material passes through the second discharge cavity and is discharged from the bottom end of the blanking pipe, thus completing the blanking work. In addition, when the first cover plate pulls the first baffle plate and the second baffle plate upward, the top surfaces of the plurality of second baffle plates will first contact the bottom surface of the first fixing ring. In this way, the second baffle plate will overcome the elastic force of the second elastic member and slide downward. In this way, the second baffle plate moves relative to the first baffle plate, so as to avoid the silicone material getting stuck in the gap between the first baffle plate and the second baffle plate, ensuring the smooth progress of the blanking work.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] Through the first auxiliary blanking component and the first partition component, the first partition component partitions the blanking pipe. In this way, it can cooperate with the first negative pressure pipe to form a negative pressure inside the blanking pipe to make the silicone material in the pipe roll more smoothly along the upstream pipe into the blanking pipe, ensuring the smooth progress of the blanking work. At the same time, through the swinging mechanism, a plurality of pairs of material - holding plates are driven to stir the silicone material above the first partition component upward and then let it fall, which can cooperate with the first negative pressure pipe to effectively adsorb and remove the dust mixed in the silicone material, avoiding a large amount of dust floating around when the silicone material is discharged from the bottom end of the blanking pipe, and effectively improving the reliability and safety of the negative pressure device.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1 - 9, A negative pressure device for the silicone material outlet in the processing of an aviation inner lining shown in the figure, comprising: a material discharging pipe 1; a plurality of first negative pressure pipes 11 are communicated with the outer side wall of the material discharging pipe 1, a first partition component 2 is connected between the inner side walls of the material discharging pipe 1, a first auxiliary material discharging component 3 is connected in the material discharging pipe 1, both the first auxiliary material discharging component 3 and the first negative pressure pipes 11 are located above the first partition component 2, a lifting component 5 is arranged in the material discharging pipe 1, and the lifting component 5 is connected with the first partition component 2 to open or close the first partition component 2;

[0031] Filter meshes are fixedly connected to the inner wall of the air inlet ends of the first negative pressure pipe 11 and the second negative pressure pipe 12, not shown in the figure, the air outlet ends of the first negative pressure pipe 11 and the second negative pressure pipe 12 are both communicated with an air suction pump, and the output end of the air suction pump is communicated with a dust collection box, not shown in the figure;

[0032] The first auxiliary material discharging component 3 includes a fixing plate 31 connected between the inner walls of the material discharging pipe 1, a plurality of swinging mechanisms 32 are connected to the bottom of the fixing plate 31 at equal angles in a ring shape, a plurality of pairs of material holding plates 33 are connected to the plurality of swinging mechanisms 32 at equal angles in a ring shape, and each pair of two material holding plates 33 are distributed in an isosceles triangle shape and the tip parts are aligned with the axis line of the fixing plate 31.

[0033] Refer to Figure 2 and Figure 3 , The first partition component 2 includes a first fixing ring 21 fixedly connected between the inner side walls of the material discharging pipe 1, a first material falling cavity 22 in the shape of an inverted frustum is opened at the top of the first fixing ring 21, a first discharging cavity 23 is communicated with the inner bottom wall of the first material falling cavity 22, the inner bottom wall of the first discharging cavity 23 penetrates through the bottom wall of the first fixing ring 21, the first partition component 2 further includes an inverted frustum-shaped first cover plate 24 that can cover the top end of the first discharging cavity 23, the outer side surface of the first cover plate 24 can tightly abut against the top end of the first discharging cavity 23, and the first cover plate 24 is connected with the lifting component 5.

[0034] Specifically, by driving the first cover plate 24 to move up and down through the lifting component 5, the first cover plate 24 can be separated from the top end of the first discharging cavity 23 to release the partition, or the outer side surface of the first cover plate 24 can tightly abut against the top end of the first discharging cavity 23 to form a partition to prevent the silicone material from falling through the first discharging cavity 23.

[0035] Refer to Figure 3 , The inclination degree of the outer side surface of the first cover plate 24 is less than the inclination degree of the inner side wall of the first material falling cavity 22, and the included angle between the inclined surfaces of the two is not less than twenty degrees, and the outer side surface of the first cover plate 24 and the top end of the first discharging cavity 23 are in line contact.

[0036] Specifically, the angle between the inclined surface of the outer side surface of the first cover plate 24 and the inclined surface of the inner wall of the first blanking chamber 22 is not less than twenty degrees, thereby ensuring that the silicone material can smoothly pass through the first discharge chamber 23 after the first cover plate 24 is separated from the top of the first discharge chamber 23. In addition, there is a line contact between the outer side surface of the first cover plate 24 and the top of the first discharge chamber 23, thereby making it difficult for the silicone material to be crushed when the outer side surface of the first cover plate 24 is tightly against the top of the first discharge chamber 23, thereby reducing damage to the silicone material and improving the reliability and practicality of the negative pressure device.

[0037] See also Figure 4 , Figure 5 and Figure 7 The swing mechanism 32 includes a plurality of rotating seats 321 fixedly connected to the bottom of the fixed plate 31 in a ring shape at equal angles, a plurality of hinged plates 322 are hinged to the bottom of the plurality of rotating seats 321 in a ring shape at equal angles, a plurality of first electric push rods 323 are hinged to the sides of the plurality of hinged plates 322 away from the axial line of the fixed plate 31 and the diameter of the bottom surface of the fixed plate 31 in a ring shape at equal angles, and a plurality of pairs of material holding plates 33 are connected to the bottom surfaces of the plurality of hinged plates 322 in a ring shape at equal angles.

[0038] Specifically, the hinged plate 322 and the multiple pairs of material holding plates 33 can be driven to swing up and down by the extension and retraction of the first electric push rod 323, so as to complete the upward movement of the silicone material. This can not only prevent the silicone material from being blocked in the gap between the first cover plate 24 and the top of the first discharge chamber 23, making the discharge process of the silicone material smoother, but also can make the dust mixed in the silicone material more smoothly sucked away by the first negative pressure pipe 11 when the silicone material slides down from the material holding plate 33, thereby improving the dust removal effect on the silicone material and preventing the silicone material from being discharged from the bottom of the discharge pipe 1. Disperse dust.

[0039] See also Figure 4 , Figure 5 and Figure 7 Two first motors are symmetrically fixedly connected in the multiple hinged plates 322, and the output ends of the two first motors pass through the bottom wall of the hinged plate 322 and are symmetrically fixedly connected to the two first rotating shafts. Each pair of two material holding plates 33 is symmetrically fixedly sleeved on the outer circumferential surface of the two first rotating shafts, and each pair of two material holding plates 33 is symmetrically connected with two groups of material guide plates 34 on the side facing the inner wall of the discharge tube 1. Each group of multiple material guide plates 34 is equidistantly distributed along the length direction of the material holding plates 33, and the width directions of the material guide plates 34 and the material holding plates 33 are not parallel.

[0040] Specifically, when starting the two first motors to drive the two material holding plates 33 to rotate in opposite directions during the upward swing through the two first rotating shafts, the silicone materials initially lifted upward by the two material holding plates 33 will slide downward along each pair of the two material holding plates 33 respectively as the material holding plates 33 rotate. In this way, it can ensure that the silicone materials slide downward more smoothly and dispersedly, so that the first negative pressure pipe 11 can adsorb the dust mixed in the silicone materials more fully and effectively.

[0041] Refer to Figures 2 - 5 , an auxiliary material dialing assembly 4 is connected inside the blanking pipe 1. The auxiliary material dialing assembly 4 is used to make the material holding plate 33 swung to a high position more smoothly insert into the bottom of the silicone materials again.

[0042] Specifically, it enables the first auxiliary blanking assembly 3 to more smoothly lift the silicone materials above the first cover plate 24 upward repeatedly, so as to further improve the adsorption and removal effect of the dust in the silicone materials.

[0043] Refer to Figure 4 、 Figure 5 and Figure 8 , the auxiliary material dialing assembly 4 includes a fixed block 41 fixedly connected to the top of the first cover plate 24. A straight hole is formed at the top of the fixed block 41 and the bottom end of the straight hole penetrates through the bottom of the fixed block 41. A plurality of partition grooves 42 are annularly and equiangularly formed at the top of the fixed block 41. A plurality of pairs of partition plates 43 are rotationally connected in an annular and equiangular manner through first rotating rods on the inner bottom walls of the plurality of partition grooves 42. Two groups of first elastic members 44 are symmetrically fixedly connected between the side surfaces of each pair of partition plates 43 close to the partition grooves 42 and the inner side walls of the partition grooves 42. The fixing plate 31 is connected to the lifting assembly 5, and the lifting assembly 5 can first pull the fixing plate 31 upward and then pull the first cover plate 24 upward.

[0044] Specifically, while the material receiving plate 33 toggles the silicone material on the top of the first cover plate 24 upward, the lifting assembly 5 can first pull the material receiving plate 33 upward to the upper side of the fixed block 41, and then as the swing mechanism 32 drives the material receiving plate 33 to rotate towards the fixed block 41 to the vertical position, the lifting assembly 5 can drive the material receiving plate 33 to move downward and insert it into the partition groove 42. In this way, due to the blockage of the partition plate 43, the silicone material can be prevented from entering the partition groove 42, so that the material receiving plate 33 can be smoothly inserted into the bottom of the silicone material, thus providing favorable conditions for the next upward toggling of the silicone material. In addition, when the material receiving plate 33 needs to toggle the silicone material upward, the swing mechanism 32 is started to drive the material receiving plate 33 to swing upward. When the material receiving plate 33 touches the partition plate 43, it will overcome the elastic force of the first elastic member 44 and push open the partition plate 43 to continue swinging upward to toggle the silicone material. After the material receiving plate 33 separates from the partition plate 43, the partition plate 43 will close again under the elastic force of the first elastic member 44 to prevent the silicone material from entering the partition groove 42, so as to ensure that the material receiving plate 33 can be smoothly inserted into the partition groove 42 and prepare for the next upward toggling of the silicone material;

[0045] The partition plate 43 is composed of a plurality of small door plates 431 evenly distributed at equal intervals from top to bottom. Two groups of the first elastic members 44 are respectively connected between the sides of the two groups of small door plates 431 and the inner side wall of the partition groove 42. In this way, the small door plates 431 can be closed separately, so that the opening time of each pair of small door plates 431 can be shortened, effectively preventing the silicone material from entering the partition groove 42, ensuring that the subsequent material receiving plate 33 can be smoothly inserted into the partition groove 42, and ensuring that the toggling operation of the silicone material can be carried out smoothly.

[0046] Refer to Figure 2 and Figure 3 As shown in, the lifting assembly 5 includes a connecting block 51 fixedly connected between the inner side walls of the feeding pipe 1 through a cross bar. The bottom of the connecting block 51 is fixedly connected with a second electric push rod 52. The output end of the second electric push rod 52 is fixedly connected with the top of the fixing plate 31. The lifting assembly 5 further includes a first telescopic rod 53 fixedly connected between the bottom of the fixing plate 31 and the top surface of the first cover plate 24. The first telescopic rod 53 is located in the straight hole of the fixed block 41.

[0047] Specifically, when the second electric push rod 52 starts to contract, under the action of the first telescopic rod 53, the fixed plate 31 will be driven to move upward first. When the first telescopic rod 53 extends to the longest position, the first cover plate 24 will be pulled upward to release the partition function of the first partition assembly 2. In this way, when feeding is not required, the second electric push rod 52 can only drive the material receiving plate 33 to reciprocate up and down to repeatedly stir the silicone material on the upper side of the first cover plate 24, so as to effectively adsorb and remove the dust in the silicone material, and further more effectively avoid a large amount of dust from floating around when the silicone material is discharged from the bottom end of the feeding pipe 1.

[0048] Refer to Figure 1 and Figure 2 , a second partition assembly 7 is connected between the inner side walls of the feeding pipe 1. A plurality of second negative pressure pipes 12 are communicated with the outer side wall of the feeding pipe 1. The second negative pressure pipes 12 are located between the first partition assembly 2 and the second partition assembly 7. The second partition assembly 7 includes a second fixing ring 71 fixedly connected between the inner side walls of the feeding pipe 1. A frustum-shaped second blanking cavity is formed at the top of the second fixing ring 71. A second discharge cavity is communicated with the inner bottom wall of the second blanking cavity. The inner bottom wall of the second discharge cavity penetrates through the bottom wall of the second fixing ring 71. The second partition assembly 7 further includes a frustum-shaped second cover plate 72 that can cover the top end of the second discharge cavity. The outer side surface of the second cover plate 72 can tightly abut against the top end of the second discharge cavity. A second auxiliary feeding assembly 6 is connected to the bottom of the first cover plate 24. The second auxiliary feeding assembly 6 is located above the second cover plate 72. A second telescopic rod 54 is fixedly connected between the second auxiliary feeding assembly 6 and the top surface of the second cover plate 72. The second auxiliary feeding assembly 6 can cooperate with the second negative pressure pipes 12 to more thoroughly adsorb and remove the dust in the silicone material.

[0049] Specifically, through the first cover plate 24 and the second telescopic rod 54, the second cover plate 72 can be first pulled upward away from the top end of the second discharge cavity, so as to release the partition function of the second partition assembly 7, enabling the silicone material to pass through the second discharge cavity and be discharged from the bottom end of the feeding pipe 1. At the same time, the second auxiliary feeding assembly 6 can stir the falling silicone material to enhance the adsorption effect of the second negative pressure pipes 12 on the dust mixed in the silicone material.

[0050] Refer to Figure 6 and Figure 9, the second auxiliary blanking component 6 includes a mounting block 61 fixedly connected to the bottom of the first cover plate 24. A second motor is fixedly connected inside the mounting block 61. The output end of the second motor penetrates the bottom wall of the mounting block 61 and is fixedly connected to a fixed column 62. A plurality of first dial plates 63 are fixedly connected to the outer peripheral surface of the fixed column 62 at equal angles in a ring shape. A plurality of moving grooves 64 are opened on the outer peripheral surface of the fixed column 62 at equal angles in a ring shape. The plurality of moving grooves 64 and the plurality of first dial plates 63 are distributed more. A square rod 65 is fixedly connected between the inner top wall and the inner bottom wall of the moving groove 64. A plurality of second dial plates 66 are movably sleeved on the outer peripheral surfaces of the plurality of square rods 65 at equal angles in a ring shape. A second elastic member 67 is fixedly connected between the bottom of the second dial plate 66 and the inner bottom wall of the moving groove 64. The top surface of the second dial plate 66 is located above the top surface of the first dial plate 63.

[0051] Specifically, the second motor drives the fixed column 62 to rotate. The fixed column 62 drives the plurality of first dial plates 63 and the plurality of second dial plates 66 to rotate to stir the falling silicone material, so that the dust mixed in the silicone material can be better separated from the silicone material, so that the second negative pressure pipe 12 can more smoothly adsorb the dust. At the same time, after the fixed column 62 drives the second telescopic rod 54 to extend to the longest position, it will continue to pull the second cover plate 72 upward to separate from the top end of the second discharge cavity, so as to release the partition function of the second partition component 7 so that the silicone material passes through the second discharge cavity and is discharged from the bottom end of the blanking pipe 1, thus completing the blanking work. In addition, when the first cover plate 24 pulls the first dial plate 63 and the second dial plate 66 upward, the top surfaces of the plurality of second dial plates 66 will first contact the bottom surface of the first fixing ring 21, so that the second dial plate 66 will overcome the elastic force of the second elastic member 67 and slide downward, so that the second dial plate 66 moves relative to the first dial plate 63, so as to avoid the silicone material being stuck in the gap between the first dial plate 63 and the second dial plate 66 and ensure the smooth progress of the blanking work.

[0052] Working principle: Start the suction pump to suck air from the blanking pipe 1 through the first negative pressure pipe 11 and the second negative pressure pipe 12, so as to cooperate with the partition functions of the first partition component 2 and the second partition component 7 to form a negative pressure in the blanking pipe 1, so as to ensure that the silicone material can more smoothly roll from the upstream pipeline into the blanking pipe 1 and ensure the smooth progress of the blanking work.

[0053] At the same time, when there is no need to unload the material, the organic silicon material will accumulate on the upper side of the first cover plate 24. Then, when the second electric push rod 52 is started to retract, the fixed plate 31 will be driven to move upward under the action of the first telescopic rod 53, and the second electric push rod 52 will be extended before the first telescopic rod 53 is extended to the longest position. In this way, only the material holding plate 33 can be driven to reciprocate up and down without driving the first cover plate 24 to move upward. At the same time, starting the first electric push rod 323 to retract can drive the hinged plate 322 and multiple pairs of material holding plates 33 to swing up and down, thereby completing the upward movement of the organic silicon material. In this way, not only can the organic silicon material be prevented from being blocked in the gap between the first cover plate 24 and the top of the first discharge chamber 23, making the unloading process of the organic silicon material smoother, but also when the organic silicon material slides down from the material holding plate 33, the dust mixed in the organic silicon material can be more smoothly sucked away by the first negative pressure pipe 11, thereby improving the dust removal effect on the organic silicon material and preventing the organic silicon material from being discharged from the bottom end of the unloading pipe 1. After the dust is scattered everywhere.

[0054] And while the material holding plate 33 pushes the organic silicon material on the top of the first cover plate 24 upward, the lifting component 5 can first pull the material holding plate 33 upward to the upper side of the fixed block 41, and then as the swing mechanism 32 drives the material holding plate 33 to rotate to a vertical position in the direction close to the fixed block 41, the lifting component 5 can drive the material holding plate 33 to move downward and insert it into the partition groove 42. In this way, due to the obstruction of the partition plate 43, the organic silicon material can be prevented from entering the partition groove 42, so that the material holding plate 33 is smoothly inserted into the bottom of the organic silicon material, thereby providing a convenient way for pushing the organic silicon material upward next time. Favorable conditions. In addition, when the holding plate 33 needs to lift the silicone material upward, the swing mechanism 32 is started to drive the holding plate 33 to swing upward. When the holding plate 33 touches the partition 43, the elastic force of the first elastic member 44 is overcome and the partition 43 is pushed open and continues to swing upward to lift the silicone material. After the holding plate 33 is separated from the partition 43, the partition 43 is closed again under the elastic force of the first elastic member 44 to prevent the silicone material from entering the partition groove 42, thereby ensuring that the holding plate 33 can be smoothly inserted into the partition groove 42 and prepare for the next time the silicone material is lifted upward.

[0055] When material is needed, the second electric push rod 52 is started to retract and the first cover plate 24 is driven away from the top of the first discharge chamber 23 through the first telescopic rod 53 so that the silicone material passes through the first discharge chamber 23 and falls on the upper side of the second cover plate 72. At the same time, the second motor is started to drive the fixed column 62 to rotate. The fixed column 62 will drive multiple first shift plates 63 and multiple second shift plates 66 to rotate to shift the falling silicone material, so that the dust mixed in the silicone material can be better separated from the silicone material, so that the second negative pressure tube 12 can absorb the dust more smoothly.

[0056] When blanking is required, the first cover plate 24 is lifted by the second electric push rod 52. After the second telescopic rod 54 is driven by the fixed column 62 to extend to the longest position, it will continue to pull the second cover plate 72 upward to separate from the top end of the second discharge cavity. In this way, the partition function of the second partition assembly 7 can be released, so that the silicone material can pass through the second discharge cavity and be discharged from the bottom end of the blanking pipe 1, thus completing the discharging work.
