Description

Technical Field

[0001] The utility model relates to the technical field of canning devices, in particular to a canning device for aqueous emulsion pesticides. Background Art

[0002] An aqueous emulsion pesticide is a preparation in which a liquid pesticide technical material in liquid form or prepared by mixing with a solvent is dispersed in water in the form of small droplets with a size of 0.5 - 1.5 microns, and its appearance is a milky white milk-like liquid.

[0003] Due to its relatively weak fluidity compared with aqueous solutions, during the filling process of aqueous emulsion pesticides, residues and dripping are likely to occur at the end of the filling head. Therefore, when filling aqueous emulsion pesticides, a drip-proof receiving cylinder is provided below the filling head. There is a type of filling device on the market where the receiving cylinder fits against the bottom of the filling head. When the filling head moves downward, it can squeeze the receiving cylinder to make it flip. Eventually, the opening of the receiving cylinder is inclined downward and aligned with the top opening of the packaging barrel of the aqueous emulsion pesticide, so that the aqueous emulsion pesticide received inside the receiving cylinder flows back into the packaging barrel again. After the filling head moves upward, the receiving cylinder will automatically reset to an inclined upward state under the action of a torsion spring, realizing the operations of blocking and receiving the bottom of the filling head.

[0004] However, in the above structure, when the filling head moves downward, it always forms extrusion with the receiving cylinder, that is, the receiving cylinder will generate friction on the outer wall of the filling head, and the aqueous emulsion pesticide flowing out from inside the receiving cylinder will pass through the outer wall of the filling head and then fall into the packaging barrel. In this way, during long-term use, not only will the outer wall of the filling head be worn and scratched, but also the outer wall of the filling head will have residues of aqueous emulsion pesticides, which need to be cleaned later. Based on this, a canning device for aqueous emulsion pesticides is provided. Summary of the Invention

[0005] The purpose of the utility model is to provide a canning device for aqueous emulsion pesticides to solve the problems in the above background.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A canning device for aqueous emulsion pesticides, including a filling machine main body and a filling assembly arranged on one side of the filling machine main body. The filling assembly includes a lifting seat, a connecting arm, and a filling three-way valve.

[0007] The lifting seats are distributed on the outer side, the connecting arm is fixed at one end of the lifting seat and extends to the front of the filling machine main body, and the filling three-way valve is installed at the end of the connecting arm away from the lifting seat.

[0008] A drip-proof component is further arranged on one side of the outer wall of the filling machine main body, and the drip-proof component is used for drip-proof protection of the bottom end of the filling three-way valve.

[0009] The anti-drip component includes a concave fixing frame, a material receiving cylinder, a rotating shaft, a driven gear, and a linkage tooth arm;

[0010] The concave fixing frame is fixed to one side of the outer wall of the filling machine main body and extends to the front of the filling machine main body. The rotating shafts are symmetrically fixed to both ends of the outer wall of the material receiving cylinder. The material receiving cylinder is rotatably connected to the inner side of the concave fixing frame through the rotating shafts. When the material receiving cylinder is inclined upward, the opening of the material receiving cylinder is located directly below the filling three-way valve, so as to realize the anti-drip protection of the filling three-way valve;

[0011] One of the rotating shafts penetrates to the outer end of the concave fixing frame and is fixedly connected to the driven gear. The linkage tooth arm is fixed to one end of the lifting seat and the bottom end of the linkage tooth arm extends to one side of the driven gear. A tooth arm meshing with the driven gear is formed at the bottom of one side of the linkage tooth arm. The up and down movement of the linkage tooth arm is used to drive the material receiving cylinder to perform a flipping operation.

[0012] As a further solution of the present invention: The filling component further includes a fixing seat, a guide rod, and a pneumatic push rod;

[0013] There are two fixing seats and two guide rods. The two fixing seats are vertically distributed and fixed to one side of the outer wall of the filling machine main body, and the fixing seats are located above the concave fixing frame. The two guide rods are symmetrically fixed in the middle of the two fixing seats. The lifting seat is slidably sleeved outside the two guide rods;

[0014] The pneumatic push rod is fixed to the top of the lower fixing seat and the top of the output end is fixedly connected to the bottom of the lifting seat. The pneumatic push rod is used to drive the filling three-way valve to move up and down, and at the same time provide power for the flipping of the material receiving cylinder.

[0015] As a further solution of the present invention: The anti-drip component further includes a sliding weight, a limiting block, and a limiting chute;

[0016] The sliding weight is slidably connected to the inside of the material receiving cylinder. The limiting block is fixed to the top of the sliding weight. The limiting chute is formed at the top inside of the guide rod. The limiting block is slidably and limitedly connected to the inside of the limiting chute;

[0017] When the material receiving cylinder flips downward, the sliding weight slides downward under the action of its own gravity to realize the pushing of the emulsion pesticide inside the material receiving cylinder.

[0018] As a further solution of the present invention: The anti-drip component further includes a rotating convex block and a fixed convex block;

[0019] The other rotating shaft penetrates to the other end of the outer wall of the concave fixing frame and is fixedly connected to the rotating convex block. The rotating convex block is distributed on the side surface of the outer wall of the rotating shaft. The fixed convex block is fixed to the other end of the outer wall of the concave fixing frame;

[0020] When the receiving barrel is turned over and facing downward, the rotating protrusion is rotated to fit with the fixed protrusion, and the cooperation between the fixed protrusion and the receiving barrel is used to achieve the limitation of the turning angle of the receiving barrel.

[0021] As a further solution of the utility model: the side of the material receiving barrel and the sliding weight away from the concave fixing frame are both inclined structures, and the angles of the two inclined surfaces match each other.

[0022] As a further solution of the utility model: the top of the side of the linkage tooth arm is a smooth surface and does not contact the driven gear, and the bottom end level of the filling three-way valve is higher than the level of the uppermost tooth block on the linkage tooth arm.

[0023] Compared with the prior art, the beneficial effects of the utility model are:

[0024] By setting up an anti-drip component, the water-emulsion pesticide dripping from the bottom of the filling three-way valve can be received by the material receiving barrel. At the same time, when the filling three-way valve moves downward, the downward movement force can be used to drive the material receiving barrel to flip, and the water-emulsion pesticide inside the material receiving barrel can be pushed out by sliding the sliding weight block, so that the water-emulsion pesticide can flow back into the packaging barrel to achieve the recovery of the water-emulsion pesticide. During this process, the material receiving barrel does not contact the filling three-way valve, thereby avoiding scratches on the filling three-way valve. At the same time, the water-emulsion pesticide flowing out of the material receiving barrel will not contact the surface of the filling three-way valve, thereby avoiding the presence of residual water-emulsion pesticide on the surface of the filling three-way valve.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figures 1 to 4 , in the embodiments of the present utility model, a canning device for an emulsion pesticide includes a filling machine main body 1 and a filling assembly 2 arranged on one side of the filling machine main body 1. The filling assembly 2 includes a lifting seat 203, a connecting arm 204, and a filling three-way valve 205;

[0032] The lifting seats 203 are distributed on the outer side of 101. The connecting arm 204 is fixed to one end of the lifting seat 203 and extends to the front of the filling machine main body 1. The filling three-way valve 205 is installed at the end of the connecting arm 204 away from the lifting seat 203;

[0033] On one side of the outer wall of the filling machine main body 1, a dripping prevention assembly 3 is further provided. The dripping prevention assembly 3 is used for preventing dripping at the bottom of the filling three-way valve 205;

[0034] The dripping prevention assembly 3 includes a concave fixing frame 301, a material receiving cylinder 302, a rotating shaft 303, a driven gear 304, and a linkage tooth arm 305;

[0035] The concave fixing frame 301 is fixed to one side of the outer wall of the filling machine main body 1 and extends to the front of the filling machine main body 1. The rotating shafts 303 are symmetrically fixed to both ends of the outer wall of the material receiving cylinder 302. The material receiving cylinder 302 is rotatably connected to the inside of the concave fixing frame 301 through the rotating shafts 303. When the material receiving cylinder 302 is inclined upward, the opening of the material receiving cylinder 302 is located directly below the filling three-way valve 205, so as to realize the dripping prevention protection of the filling three-way valve 205;

[0036] One rotating shaft 303 penetrates to the outer end of the concave fixing frame 301 and is fixedly connected to the driven gear 304. The linkage tooth arm 305 is fixed to one end of the lifting seat 203 and the bottom end of the linkage tooth arm 305 extends to one side of the driven gear 304. A tooth arm meshing with the driven gear 304 is formed at the bottom of one side of the linkage tooth arm 305. The up and down movement of the linkage tooth arm 305 is used to drive the material receiving cylinder 302 to perform a flipping operation;

[0037] The filling assembly 2 further includes a fixed seat 201, a guide rod 202, and a pneumatic push rod 206;

[0038] There are two fixing seats 201 and two guide rods 202. The two fixing seats 201 are vertically distributed and fixed on one side of the outer wall of the filling machine main body 1, and the fixing seat 201 is located above the concave fixing frame 301. The two guide rods 202 are symmetrically fixed between the two fixing seats 201, and the lifting seat 203 is slidably sleeved on the outer sides of the two guide rods 202;

[0039] The pneumatic push rod 206 is fixed to the top of the lower fixing seat 201, and the top of the output end of 207 is fixedly connected to the bottom of the lifting seat 203. The pneumatic push rod 206 is used to drive the filling three-way valve 205 to move up and down, and at the same time provide power for the flipping of the material receiving cylinder 302.

[0040] In this embodiment: when this device is in use, the packaging barrel is transported to the lower part of the filling three-way valve 205 through the cooperation of an external conveying device, and the opening of the packaging barrel is aligned with the bottom end of the filling three-way valve 205. Then, the pneumatic push rod 206 is started. The pneumatic push rod 206 drives the lifting seat 203, the connecting arm 204, the filling three-way valve 205 and the linkage tooth arm 305 to move downward as a whole. The linkage tooth arm 305 drives the driven gear 304 to rotate. The driven gear 304 drives the material receiving cylinder 302 to flip through the rotating shaft 303, so that the material receiving cylinder 302 flips from the inclined upward state to the inclined downward state, so that the material receiving cylinder 302 will not interfere with the downward movement of the filling three-way valve 205. At the same time, the emulsion pesticide inside the material receiving cylinder 302 can flow downward into the packaging barrel to realize the recovery of the emulsion pesticide;

[0041] Finally, the bottom end of the filling three-way valve 205 penetrates into the packaging barrel, the filling three-way valve 205 is controlled to open for filling operation. After the penetration is completed, the filling three-way valve 205 is closed, and the pneumatic push rod 206 is started to run in the reverse direction, so that the filling three-way valve 205 is reset to its original position. At the same time, when the tooth block on the linkage tooth arm 305 contacts the driven gear 304 again, it can drive the driven gear 304 to rotate, and then the material receiving cylinder 302 is reset to the inclined upward state to realize the shielding of the bottom end of the filling three-way valve 205. When there is residual emulsion pesticide dripping at the bottom end of the filling three-way valve 205, the dripping emulsion pesticide can be received;

[0042] Through the cooperation of the above-mentioned multiple parts, the anti-dripping protection of the filling three-way valve 205 can be realized. At the same time, the material receiving cylinder 302 does not come into contact and friction with the filling three-way valve 205, avoiding scratching and damage to the filling three-way valve 205. At the same time, the emulsion pesticide flowing out of the material receiving cylinder 302 does not contact the surface of the filling three-way valve 205, avoiding the situation of residual emulsion pesticide on the surface of the filling three-way valve 205.

[0043] Please refer to with emphasis Figures 1 to 4 , the anti-dripping component 3 further includes a sliding weight 306, a limiting block 307, a limiting chute 308, a rotating convex block 309, and a fixed convex block 310;

[0044] The sliding weight 306 is slidably connected to the inner side of the material receiving cylinder 302. The limiting block 307 is fixed to the top of the sliding weight 306. The limiting sliding groove 308 is formed on the inner top of the guide rod 202. The limiting block 307 is slidably connected to the inner side of the limiting sliding groove 308 in a limiting manner;

[0045] When the material receiving cylinder 302 is turned downward, the sliding weight 306 slides downward under its own gravity to push the emulsion pesticide inside the material receiving cylinder 302;

[0046] Another rotating shaft 303 penetrates to the other end of the outer wall of the concave fixing frame 301 and is fixedly connected to the rotating convex block 309. The rotating convex blocks 309 are distributed on the side surface of the outer wall of the rotating shaft 303. The fixed convex block 310 is fixed to the other end of the outer wall of the concave fixing frame 301;

[0047] When the material receiving cylinder 302 is turned downward, the rotating convex block 309 rotates to fit with the fixed convex block 310. The cooperation between the fixed convex block 310 and the material receiving cylinder 302 is used to limit the turning angle of the material receiving cylinder 302;

[0048] In this embodiment: when the material receiving cylinder 302 is in an inclined upward state, the sliding weight 306 is received inside the material receiving cylinder 302 under its own gravity. When the material receiving cylinder 302 rotates to an inclined downward state, the sliding weight 306 slides downward under its own gravity, which can not only push out the emulsion pesticide inside the material receiving cylinder 302, but also keep the material receiving cylinder 302 in a stable inclined downward state through the gravity of the sliding weight 306;

[0049] It should be noted that: the cooperation between the limiting sliding groove 308 and the limiting block 307 is used to realize the sliding limit and guidance of the sliding weight 306;

[0050] The cooperation between the rotating convex block 309 and the fixed convex block 310 can limit the turning angle of the material receiving cylinder 302.

[0051] Please refer specifically to Figures 1 to 4 , one side of the material receiving cylinder 302 and the sliding weight 306 away from the concave fixing frame 301 are both in an inclined plane structure, and the inclined plane angles of the two match.

[0052] In this embodiment: due to the inclined plane structure of the material receiving cylinder 302, it will not come into contact or collision with the bottom end of the filling three-way valve 205 when it is inclined upward;

[0053] Due to the inclined plane structure of the sliding weight 306, when the sliding weight 306 is inclined downward, the emulsion pesticide can flow downward along its inclined plane better.

[0054] Please refer specifically to Figures 1 to 4, the top side of the linkage tooth arm 305 is a smooth surface and does not contact the driven gear 304, and the horizontal height of the bottom end of the filling three-way valve 205 is higher than the horizontal height of the uppermost tooth block on the linkage tooth arm 305.

[0055] In this embodiment: through this structure, when the linkage tooth arm 305 moves downward and the tooth block on the linkage tooth arm 305 separates from the driven gear 304, the linkage tooth arm 305 will not contact the driven gear 304;

[0056] Due to the structure that the horizontal height of the bottom end of the filling three-way valve 205 is higher than the horizontal height of the uppermost tooth block on the linkage tooth arm 305, when the filling three-way valve 205 moves upward and the bottom end of the filling three-way valve 205 exceeds the driven gear 304, the tooth block on the linkage tooth arm 305 will contact the driven gear 304. At this time, the tipping of the material receiving cylinder 302 will not collide with the filling three-way valve 205, thus ensuring the smooth operation of the equipment.

[0057] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
