Description

Technical Field

[0001] This utility model relates to the field of water-soluble fertilizer production technology, specifically to an auxiliary device for sealing barrels in a water-soluble fertilizer production line. Background Technology

[0002] In the production of water-soluble fertilizers, sealing the containers is a crucial step in the product packaging process, and its quality directly affects the storage, transportation, and effectiveness of the fertilizer. With the continuous expansion of water-soluble fertilizer production scale and the increasing level of automation, higher demands are being placed on the efficiency and quality of container sealing operations.

[0003] While existing automated sealing equipment has improved production efficiency to some extent, it still has many shortcomings in practical use. For example, some equipment lacks flexible height adjustment, making it unable to adapt to the sealing needs of different sized barrels. This necessitates frequent equipment changes or complex adjustments, increasing production costs and operational difficulty. Furthermore, existing clamping mechanisms often cannot be precisely adjusted according to the barrel size, leading to unstable clamping. During sealing, the barrel is prone to shaking or displacement, resulting in uneven sealing and reduced sealing performance and aesthetics. Additionally, existing edge-trimming mechanisms are complex in structure, cumbersome to operate, and difficult to precisely control the trimming force and speed, easily leading to over- or under-trimming, affecting the folding effect of the lid and the sealing quality. Therefore, we propose an auxiliary barrel sealing device for water-soluble fertilizer production lines. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary device for sealing barrels in a water-soluble fertilizer production line, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a mounting frame, with a mounting sleeve fixedly mounted at the bottom of the mounting frame. A lifting sleeve is slidably mounted inside the mounting sleeve. A first screw is rotatably mounted inside the mounting sleeve via a bearing, passing through the lifting sleeve and threadedly connected to it. A fixing plate is fixedly mounted at the bottom of the lifting sleeve. Several electric push rods are evenly fixedly mounted at the bottom of the fixing plate. A trimming mechanism is fixedly mounted at the end of the telescopic arm of each electric push rod. A clamping mechanism is also fixedly mounted inside the mounting frame. The clamping mechanism includes mounting shells symmetrically fixedly mounted on both sides of the mounting frame. Slider blocks are symmetrically slidably mounted on the front and rear sides inside the mounting shells. A bidirectional screw is rotatably mounted inside the mounting shells via a bearing, passing through and threadedly connected to the two sliders. A clamping plate is fixedly mounted at the bottom of each slider. A first gear is connected to the bidirectional screw via a key. Racks are fixedly mounted on the outer walls of both sides of the fixing plate, meshing with the first gear.

[0006] Preferably, a worm gear is keyed to the first screw inside the mounting bracket, and a worm is rotatably mounted on the mounting bracket, with the worm and worm gear meshing with each other.

[0007] Preferably, the edge-gathering mechanism includes a mounting plate fixedly installed at the bottom telescopic end of the electric push rod. Several mounting plates are evenly fixedly installed on the bottom of the mounting plate. A through hole is provided through the mounting plate. A slide rod is slidably installed in the through hole. A movable plate is fixedly installed at the inner end of the slide rod. Several fixing blocks are evenly fixedly installed on the side wall of the movable plate. An edge-gathering plate is fixedly installed on the inner wall of the fixing blocks.

[0008] Preferably, the mounting plate is also provided with a second screw via a bearing, the second screw passing through the movable plate and being threadedly connected to the movable plate.

[0009] Preferably, the mounting plate is further provided with a drive mechanism that operates with the drive edge-gathering mechanism. The drive mechanism includes a second gear rotatably mounted on the mounting plate, a second bevel gear fixedly mounted on the inner wall of the second gear, and a first bevel gear fixedly mounted on the outer end of the second screw. The first bevel gear and the second bevel gear mesh with each other.

[0010] Preferably, a support plate is fixedly installed on the side wall of the rear mounting plate, and a drive motor is fixedly installed on the top of the support plate. A drive gear is connected to the power output shaft of the drive motor via a key, and the drive gear meshes with the second gear.

[0011] Preferably, a servo motor is fixedly mounted on the outer wall of the front side of the mounting bracket.

[0012] Preferably, the power output shaft of the servo motor is fixedly connected to the worm gear via a coupling.

[0013] Preferably, a first limiting block is fixedly installed at the outer end of the slide bar.

[0014] Preferably, a second limiting block is fixedly installed at the outer end of the second screw.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: the servo motor drives the worm gear to rotate, which in turn drives the worm wheel and the first screw to rotate, so that the lifting sleeve moves up and down in the mounting sleeve, realizing flexible adjustment of the height of the edge-sealing mechanism. It can adapt to the sealing requirements of barrels of different specifications, without the need for frequent equipment replacement or complex adjustments, effectively reducing production costs and operational difficulty. When the lifting sleeve moves, the racks on both sides of the fixed plate drive the first gear on the bidirectional screw to rotate, so that the bidirectional screw drives the slider and clamping plate to move. The clamping position can be precisely adjusted according to the size of the barrel, ensuring clamping stability and avoiding barrel shaking or displacement during sealing, thus improving the neatness and sealing performance of the seal.

[0016] In addition, the electric push rod can move the mounting plate and the entire edge-sealing mechanism closer to the bucket lid. The drive motor drives the second screw to rotate through the transmission of the drive gear, the second gear, the second bevel gear and the first bevel gear, so that the moving plate and the edge-sealing plate move, precisely controlling the edge-sealing force and speed, preventing over- or under-sealing, ensuring the folding effect and sealing quality of the bucket lid. The first limit block on the slide rod and the second limit block on the second screw can prevent the parts from falling off, ensuring the stable operation of the equipment, improving the utilization efficiency of the edge-sealing plate, and improving the overall efficiency and quality of the water-soluble fertilizer bucket sealing operation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides a technical solution: such as Figures 1-4The illustrated auxiliary equipment for sealing barrels in a water-soluble fertilizer production line includes a mounting frame 1. A mounting sleeve 2 is fixedly mounted on the bottom of the mounting frame 1. A lifting sleeve 3 is slidably mounted inside the mounting sleeve 2. A fixing plate 4 is fixedly mounted on the bottom of the lifting sleeve 3. Several electric push rods 14 are evenly fixedly mounted on the bottom of the fixing plate 4. A trimming mechanism is fixedly mounted at the end of the telescopic arm of each electric push rod 14. A clamping mechanism is also fixedly mounted inside the mounting frame 1. The clamping mechanism includes mounting shells 9 symmetrically fixedly mounted on both sides inside the mounting frame 1. Slider blocks 11 are symmetrically slidably mounted on the front and rear sides inside the mounting shells 9. A bidirectional screw 10 is rotatably mounted inside the mounting shells 9 via bearings. The bidirectional screw 10 passes through the two sliders 11 and is connected to the two sliders 11. The slider 11 is threadedly connected. Rotating the bidirectional screw 10 will move the two sliders 11 closer or further apart. A clamping plate 30 is fixedly installed at the bottom of the slider 11. Under the action of the clamping plate 30, the barrel to be sealed can be positioned and clamped, thus ensuring the sealing quality of the barrel to a certain extent. A first gear 12 is set on the bidirectional screw 10 through a key connection. A rack 13 is fixedly installed on the outer walls of both sides of the fixing plate 4. The rack 13 and the first gear 12 mesh with each other. When the fixing plate 4 drives the edge-gathering mechanism to move up and down, the clamping plate 30 can be moved under the action of the rack 13 and the first gear 12, thus better clamping and positioning the barrel.

[0024] The first screw 5 is rotatably mounted inside the mounting sleeve 2 via a bearing. The first screw 5 passes through the lifting sleeve 3 and is threadedly connected to the lifting sleeve 3. Rotating the first screw 5 will drive the lifting sleeve 3 to move up and down, thereby adjusting the height of the edge-sealing mechanism and better meeting the subsequent sealing work of the barrel.

[0025] A worm gear 6 is keyed to the first screw 5 inside the mounting frame 1. A worm 7 is rotatably mounted on the mounting frame 1, and the worm 7 meshes with the worm gear 6. Rotating the worm 7 will drive the first screw 5 to rotate via the worm gear 6. In addition, because the worm gear 6 and the worm 7 have a self-locking function, the height of the edge-gathering mechanism and the position of the clamping plate 30 after adjustment can be restricted, thereby ensuring the sealing quality of the barrel. A servo motor 8 is fixedly mounted on the front outer wall of the mounting frame 1. The power output shaft of the servo motor 8 is fixedly connected to the worm 7 via a coupling. The servo motor 8 can then drive the worm 7 to rotate.

[0026] The edge-sealing mechanism includes a mounting plate 15 fixedly installed at the bottom telescopic end of the electric push rod 14. Several mounting plates 17 are evenly fixedly installed on the bottom of the mounting plate 15. A through hole is provided through the mounting plate 17, and a sliding rod 18 is slidably installed in the through hole. A movable plate 20 is fixedly installed on the inner end of the sliding rod 18. Several fixing blocks 22 are evenly fixedly installed on the side wall of the movable plate 20. An edge-sealing plate 23 is fixedly installed on the inner wall of the fixing blocks 22. At this time, the sliding rod 18 can drive the movable plate 20 to move, thereby folding the side wall of the lid and completing the sealing work of the barrel. A second screw 21 is also rotatably installed on the mounting plate 17 through a bearing. The second screw 21 passes through the movable plate 20 and is threadedly connected to the movable plate 20. At this time, rotating the second screw 21 can drive the movable plate 20 to move, thereby folding the lid by the edge-sealing plate 23, thus ensuring the sealing work of the barrel.

[0027] The mounting plate 15 is also equipped with a drive mechanism that operates with the edge-gathering mechanism. The drive mechanism includes a second gear 16 rotatably mounted on the mounting plate 15, a second bevel gear 26 fixedly mounted on the inner wall of the second gear 16, and a first bevel gear 25 fixedly mounted on the outer end of the second screw 21. The first bevel gear 25 and the second bevel gear 26 mesh with each other. When the second gear 16 is rotated, the second screw 21 is rotated through the second bevel gear 26 and the first bevel gear 25, thereby driving the edge-gathering plate 23 to move, and thus performing the edge-gathering work of the bucket body. A support plate 27 is fixedly mounted on the side wall of the rear mounting plate 17. A drive motor 28 is fixedly mounted on the top of the support plate 27. A drive gear 29 is connected to the power output shaft of the drive motor 28 by a key. The drive gear 29 meshes with the second gear 16. When the drive motor 28 is rotated, the second gear 16 is rotated through the drive gear 29, and then the second screw 21 is rotated through the second bevel gear 26 and the first bevel gear 25, thereby performing the edge-gathering work of the bucket lid through the edge-gathering plate 23.

[0028] A first limiting block 19 is fixedly installed at the outer end of the slide rod 18, and a second limiting block 24 is fixedly installed at the outer end of the second screw 21. At this time, under the action of the first limiting block 19 and the second limiting block 24, the efficiency of the edge trimming plate 23 is ensured.

[0029] Working principle: First, place the barrel to be sealed in a suitable position within the mounting frame 1. Start the servo motor 8, whose power output shaft drives the worm gear 7 to rotate via a coupling. Because the worm gear 7 meshes with the worm wheel 6, the worm wheel 6 rotates accordingly, thereby driving the first screw 5 to rotate. The first screw 5 passes through the lifting sleeve 3 and is threadedly connected to it. Under the action of the thread, the lifting sleeve 3 moves up and down within the mounting sleeve 2. The bottom of the lifting sleeve 3 is fixed with a fixing plate 4, which drives the electric push rod 14 and the edge-gathering mechanism at its bottom to move up and down, thereby adjusting the height of the edge-gathering mechanism to meet the sealing requirements of different barrels. At the same time, the racks 13 on both sides of the outer wall of the lifting sleeve 3 mesh with the first gear 12 on the bidirectional screw 10. When the lifting sleeve 3 moves, it drives the bidirectional screw 10 to rotate. The bidirectional screw 10 passes through the front and rear sliders 11 within the mounting shell 9 and is threadedly connected to them, thereby moving the front and rear sliders 11 closer or further apart. The clamping plate 30 at the bottom of the sliders 11 moves accordingly, positioning and clamping the barrel.

[0030] After the height is adjusted, the telescopic arm of the electric push rod 14 extends, driving the edge-sealing mechanism closer to the bucket lid. At this time, the drive motor 28 starts, and the drive gear 29 on its power output shaft drives the second gear 16 to rotate. The second bevel gear 26 on the inner wall of the second gear 16 meshes with the first bevel gear 25 at the outer end of the second screw 21, driving the second screw 21 to rotate. The second screw 21 passes through the moving plate 20 and is threadedly connected to the moving plate 20. The moving plate 20 moves under the guidance of the slide rod 18, and the edge-sealing plate 23 on the side wall fixing block 22 of the moving plate 20 moves accordingly, folding the side wall of the bucket lid to complete the sealing work. The first limiting block 19 on the outer side of the slide rod 18 and the second limiting block 24 on the outer side of the second screw 21 can prevent the parts from falling off and ensure the efficiency of the edge-sealing plate 23.
