[0024] Beneficial effects of the present invention:

[0025] 1. The present invention realizes the linkage operation of the bag feeding mechanism and the bag shifting mechanism by designing a traction component, that is, after the bag body is in place, as the push plate continues to apply thrust to the docking plate, the mouth of the packaging bag delivered to the bottom of the support plate can be automatically opened, which is convenient for the powder filling tube to fill pesticide powder. Compared with the prior art, the two mechanisms operate synchronously, which reduces the number of driving sources used for the entire equipment, reduces power consumption, and thus reduces packaging costs.

[0026] 2. The present invention realizes the linkage operation of the pressing mechanism and the sealing mechanism by designing a transmission component, that is, while the pressing roller presses the outer wall of the packaging bag containing the pesticide powder from bottom to top, the two heat-sealing plates can automatically move toward the bag opening, so that the pesticide powder is more dispersedly stored inside the packaging bag through pressing, and the subsequent caking caused by concentrated accumulation at a certain position in the packaging bag is prevented, which affects the use. At the same time, the remaining air in the bag can be discharged before sealing, so as to prevent the subsequent storage from being damp and causing the efficacy to be reduced, thereby improving the packaging quality of the pesticide powder.

[0027] 3. Combining the beneficial effects of 1 and 2, the bag feeding mechanism and the bag shifting mechanism can operate in conjunction, and the pressing mechanism and the sealing mechanism can operate in conjunction, which greatly reduces the number of driving sources used for the entire equipment, thereby minimizing the overall structure of the equipment to the greatest extent, reducing the cost and occupied space of the equipment, and at the same time facilitating the use of other equipment, thereby improving the practicality and flexibility of the equipment.

[0028] 4. The present invention designs a bag feeding mechanism, namely a material placing rack, a pushing assembly and four first electric suction cups, and designs a screw slide at the same time, so as to realize automatic loading of packaging bags, and at the end of each loading, it is just located between the four first electric suction cups and the four second electric suction cups, so as to facilitate the subsequent rapid bag opening, reduce the processing steps, and further help to improve the packaging efficiency of pesticide powder.

[0029] 5. The present invention is designed with two movable blocks and two stoppers, which can quickly block the first T-shaped plate after the four first electric suction cups are in place, thereby limiting the first T-shaped plate and ensuring that it does not move forward any further. At the same time, by designing the push block, docking plate, telescopic spring, spline and keyway, after the first T-shaped plate stops moving forward, the push block can be driven to move forward through the connecting rod, thereby contacting the docking plate, thereby driving the four second electric suction cups to move and open the bag opening, thereby facilitating the filling of pesticide powder, thereby improving the packaging accuracy, preventing the pesticide powder from leaking, and avoiding waste of resources.

[0051] Reference Figures 1 to 10As shown, the pushing assembly includes a first electric push rod 25, a connecting rod 26, a sleeve block 27 and a push block 28. A support rod is fixedly provided on the top of the base. The first electric push rod 25 is inserted into the top of the support rod. The connecting rod 26 is fixedly provided on its output end. The push block 28 is fixedly provided at one end of the connecting rod 26 away from the first electric push rod 25. The sleeve block 27 is fixedly provided on the outer wall of the first T-shaped plate 14. A key groove 29 is provided at one end of the connecting rod 26 away from the support rod. The connecting rod 26 is plugged into the sleeve block 27. A socket for the connecting rod 26 to pass through is provided on the outer wall of the sleeve block 27.

Each driving element on the device is electrically connected to the controller. When the pesticide powder is packaged in bags, the four first electric suction cups 12 are first started to adsorb the first packaging bag on the discharge rack 11 to achieve grabbing. Then, the first electric push rod 25 is started through the controller to make its output end extend toward the end close to the heat sealing plate 21 for the first time. Then, the first electric push rod 25 is powered off. Since its output end is fixedly connected to the connecting rod 26, the connecting rod 26 is plugged into the sleeve block 27, and the sleeve block 27 is fixedly connected to the first T-shaped plate 14, the four first electric suction cups 12 are aligned with the four second electric suction cups 16. Then, the four second electric suction cups 16 are started to adsorb the outer walls of the two ends of the packaging bag respectively.

[0052] Reference Figures 1 to 10As shown, the traction assembly includes an insertion rod 31, a swing rod 32, a pull rope 33 and a limiting wheel 34. Two movable blocks 35 are fixed on the outer wall of the first T-shaped plate 14, and two stoppers 36 are fixed on the outer wall of the vertical plate. The height of each movable block 35 is consistent with the height of a stopper 36.

A slot is opened at one end of the swing rod 32, and the insertion rod 31 is plugged into the slot. The pull rope 33 is fixed between the second T-shaped plate 18 and the end of the swing rod 32 away from the insertion rod 31 through a connecting block 49. The limiting wheel 34 is rotatably arranged on the top of the L-shaped plate. The outer wall of the rope 33 fits with the outer edge of the limiting wheel 34, and a telescopic spring 37 is sleeved on one end of the connecting rod 26 away from the supporting rod. The sleeve block 27 and the push block 28 are respectively fixedly connected to the two ends of the telescopic spring 37. A reset spring 38 is sleeved on the outer wall of each circular slide rod 17. The second T-shaped plate 18 and the L-shaped plate respectively contact the two ends of each reset spring 38. When the outer walls of the two ends of the packaging bag are respectively adsorbed, the first electric push rod 25 is restarted through the controller, so that its output end is extended again. Since the two blocks 36 and the two movable blocks 35 have been fitted after the output end is extended for the first time, the push block 28 and the docking plate 15 have also reached The first T-shaped plate 14 is in a fitted state, so when its output end is extended again, the first T-shaped plate 14 is limited and no longer slides toward the end close to the docking plate 15. Since the connecting rod 26 and the sleeve block 27 are slidably connected by the spline 30, the push block 28 is fixedly connected to the connecting rod 26. Therefore, when the output end of the first electric push rod 25 is extended again, the push block 28 will be driven to resist the docking plate 15 and slide toward the end away from the support plate through the guide rod on the top of the vertical plate, so that the telescopic spring 37 is changed from a tight state to a stretched state. Since the insertion rod 31 is plugged into the slot at one end of the swing rod 32, the swing rod 32 is rotatably connected to the support plate, so that the swing rod 3 2 rotates counterclockwise. Since the end of the swing rod 32 away from the insertion rod 31 is fixedly connected to the second T-shaped plate 18 through the pull rope 33 and the connecting block 49, and the second T-shaped plate 18 is slidably connected to the L-shaped plate through two sliding rods, under the limiting action of the limiting wheel 34, when the swing rod 32 rotates counterclockwise, the second T-shaped plate 18 and the four second electric suction cups 16 thereon are driven to slide toward the end close to the L-shaped plate through the pull rope 33, and the two return springs 38 are changed from a tight state to a stretched state, and cooperate with the four fixed first electric suction cups 12 to open the bag mouth of the packaging bag, and inject pesticide powder into the packaging bag through the powder injection tube 10.

[0053] Reference Figures 1 to 10As shown, the telescopic assembly includes a second electric push rod 39, an L-shaped push rod 40, a first pull rod 41 and two strip slide bars 42. Two limit plates are fixedly provided on the outer wall of the vertical plate, two guide rails are fixedly provided between the two limit plates, and each strip slide bar 42 is slidably provided in a guide rail. The second electric push rod 39 is fixedly provided on the outer wall of the vertical plate, and its output end passes through one of the limit plates. The L-shaped push rod 40 is fixedly provided on its output end, and the first pull rod 41 is fixedly provided between the L-shaped push rod 40 and one of the strip slide bars 42. When the packaging bag is filled with pesticide powder, the four first electric suction cups 12 are closed first. At this time, only the four second electric suction cups 16 adsorb one end of the packaging bag filled with pesticide powder to provide support, and then the connecting rod 26 is driven to retract toward the end away from the support plate through the output end of the first electric push rod 25, thereby driving the first T-shaped plate 14 and the four first electric suction cups 12 thereon to move to the initial position. In preparation for the suction and grabbing of the next packaging bag, at this time, since the sleeve block 27 and the push block 28 are respectively fixedly connected to the two ends of the telescopic spring 37, the telescopic spring 37 is changed from a stretched state to a tensioned state, and the push plate returns to its initial position under the pulling action of the telescopic spring 37, and the two reset springs 38 are synchronously changed from a stretched state to a tensioned state, so that the four second electric suction cups 16 return to their initial positions under the action of the pull rope 33 and the rocker arm 32. At this time, the second electric push rod 39 is started by the controller, so that its output end extends upward, because its output end is fixedly connected to one of the strip slide bars 42 through the L-shaped push rod 40 and the first pull rod 41, each strip slide bar 42 is slidably connected to a guide rail, so that the two strip slide bars 42 rise a certain distance. It should be noted that the highest point of this distance rise must be lower than the height of the two heat sealing plates 21, so as to ensure that the pressing roller 19 does not conflict with the heat sealing plate 21.

When the two strip slide bars 42 rise a certain distance, since the ends of the two strip slide bars 42 away from the guide rail are fixedly connected to the cross bar 43, each limit rod 44 is slidably connected to one end of the cross bar 43, and each transfer block 45 is A limit rod 44 is fixedly connected to one end away from the cross bar 43, and one end of the cross bar 43 and each adapter block 45 respectively contact the two ends of a buffer spring 46. The pressing roller 19 is rotatably connected to the two adapter blocks 45 through a hinge shaft, thereby driving the pressing roller 19 to rise vertically and press the outer wall of one end of the packaging bag from bottom to top. The buffer spring 46 enables the pressing roller 19 to have a telescopic function, which can ensure that the outer wall of the pressing roller 19 is always attached to the outer wall of one end of the packaging bag and rises vertically, thereby squeezing the pesticide powder in the packaging bag, so that the pesticide powder is more dispersed and stored inside the packaging bag, to prevent the subsequent accumulation of concentrated particles in a certain position in the packaging bag to form agglomerates that affect use. At the same time, the remaining air in the bag can be discharged before sealing to prevent the subsequent storage due to moisture and lead to reduced efficacy, thereby improving the packaging quality of the pesticide powder.

[0057] Reference Figures 1 to 10 As shown, the reciprocating sliding assembly includes a fifth gear 55, a second rack 56, a hinge block 57, a second pull rod 58 and two connecting rods 59. The fifth gear 55 is fixedly arranged at the end of the fourth shaft away from the horizontal plate. The second rack 56 is slidably arranged at the bottom of the supporting plate through a T-shaped slider. The second rack 56 is meshed with the fifth gear 55. The second pull rod 58 is fixedly arranged at one end of the second rack 56. The hinge block 57 is fixedly arranged at the end of the second pull rod 58 away from the second rack 56. Each connecting rod 59 is hingedly arranged between the top end of the hinge block 57 and the side wall of one of the mounting rods 24. When the fourth shaft rotates half a circle clockwise, since the fifth gear 55 is fixedly connected to the end of the fourth shaft away from the horizontal plate, the second gear 56 is meshed with the fifth gear 55. The bar 56 is slidably connected to the support plate through a T-shaped slider, the second rack 56 is meshed with the fifth gear 55, the second pull rod 58 is fixedly connected to one end of the second rack 56, the hinge block 57 is fixedly connected to the end of the second pull rod 58 away from the second rack 56, and the top end of the hinge block 57 and the side wall of one of the mounting rods 24 are respectively hinged to the two ends of each connecting rod 59, so that when the second rack 56 slides at the bottom of the support plate toward the end away from the support plate, it drives the two connecting rods 59 to approach each other, thereby pulling the two mounting rods 24 to approach each other, and then driving the two heat sealing plates 21 to heat press the bag mouth of the packaging bag synchronously through the four slides 23, that is, the packaging bag is sealed synchronously while the pressing roller 19 presses the packaging bag.

[0058] Reference Figures 1 to 10As shown, a screw slide 60 is fixedly provided on the top of the storage table 13, and a driving block 61 and two slide columns 62 are provided on the screw slide 60. When a pesticide powder packaging bag is filled with powder and sealed, the screw slide 60 is started. The screw slide 60 drives the packaging bags at the bottom and the top thereof to slide a certain distance toward one end close to the four first electric suction cups 12 through the driving block 61 and the two slide columns 62, so as to facilitate the pushing component to push the next packaging bag to the bag shifting mechanism.

[0059] Reference Figures 1 to 10 As shown, the material discharging rack 11 includes a bottom plate 63, a side plate 64 and a plurality of baffle rods 65. The bottom plate 63 is fixedly arranged between the driving block 61 and the top of the two sliding columns 62, and the side plate 64 is fixedly arranged at one end of the top of the bottom plate 63. An avoidance groove 66 is opened on the outer wall of the side plate 64, and a plurality of baffle rods 65 are arranged on the outer wall of the side plate 64 at equal intervals. A plurality of baffle rods 65 are installed on the top and bottom outer walls of the side plate 64 at equal intervals. An insertion gap is provided between every two baffle rods 65 on the top and bottom outer walls to facilitate the insertion of packaging bags. The bottom plate 63 supports the bottom of the packaging bag to prevent the packaging bag from falling. In conjunction with the screw slide 60, automatic grabbing of the packaging bag can be realized. The avoidance groove 66 provides an avoidance space for the connecting rod 26 when the bottom plate 63 drives the side plate 64 to slide toward one end close to the four first electric suction cups 12, so as to prevent the side plate 64 from conflicting with the connecting rod 26.

[0060] Working principle of the present invention: the equipment is equipped with a controller, and all driving elements on the equipment are electrically connected to the controller. When the pesticide powder bag packaging work is carried out, the four first electric suction cups 12 are first started to adsorb the first packaging bag on the material discharging rack 11 to achieve grabbing, and then the first electric push rod 25 is started by the controller to make its output end extend toward the end close to the heat sealing plate 21 for the first time, and then the first electric push rod 25 is powered off. Since its output end is fixedly connected to the connecting rod 26, the connecting rod 26 is plugged into the sleeve block 27, and the sleeve block 27 is fixedly connected to the first T-plate 14, the four first electric suction cups 12 are aligned with the four second electric suction cups 16, and then the four second electric suction cups 16 are started to adsorb the outer walls of the two ends of the packaging bag respectively.

[0061] After the outer walls of both ends of the packaging bag are adsorbed respectively, the first electric push rod 25 is restarted through the controller, so that its output end is extended again. Since the two stoppers 36 and the two movable blocks 35 have been fitted after the output end is extended for the first time, the push block 28 and the docking plate 15 are also in a fitted state. Therefore, when the output end is extended again, the first T-shaped plate 14 is limited and no longer continues to slide toward the end close to the docking plate 15. Since the connecting rod 26 and the sleeve block 27 are slidably connected by the spline 30, the push block 28 is fixedly connected to the connecting rod 26. Therefore, when the output end of the first electric push rod 25 is extended again, it will drive the push block 28 to contact the docking plate 15 through the guide rod at the top of the vertical plate to the end away from the support plate. The swing arm 32 is rotatably connected to the support plate due to the insertion of the insertion rod 31 and the slot at one end of the swing arm 32, so that the swing arm 32 rotates counterclockwise. Since the end of the swing arm 32 away from the insertion rod 31 is fixedly connected to the second T-shaped plate 18 through the pull rope 33 and the connecting block 49, the second T-shaped plate 18 is slidably connected to the L-shaped plate through two sliding rods. Under the limiting action of the limiting wheel 34, when the swing arm 32 rotates counterclockwise, the pull rope 33 will drive the second T-shaped plate 18 and the four second electric suction cups 16 thereon to slide toward the end close to the L-shaped plate, thereby cooperating with the four fixed first electric suction cups 12 to open the bag mouth and inject pesticide powder into the inside of the bag through the powder injection tube 10.

[0062] When the packaging bag is filled with pesticide powder, the four first electric suction cups 12 are closed first. At this time, only the four second electric suction cups 16 adsorb one end of the packaging bag containing pesticide powder to provide support. Then, the output end of the first electric push rod 25 drives the connecting rod 26 to retract toward the end away from the support plate, thereby driving the first T-shaped plate 14 and the four first electric suction cups 12 thereon to move to the initial position to prepare for the adsorption and grasping of the next packaging bag. At this time, since the sleeve block 27 and the push block 28 are respectively fixedly connected to the two ends of the telescopic spring 37, the telescopic spring 37 changes from a stretched state to a tight state, and the push plate is pulled by the telescopic spring 37 to return to its initial position. Position, the two return springs 38 are synchronously changed from a stretched state to a taut state, so that the four second electric suction cups 16 return to their initial positions under the action of the pull rope 33 and the rocker arm 32. At this time, the second electric push rod 39 is started by the controller, so that its output end extends upward. Since its output end is fixedly connected to one of the strip slide bars 42 through the L-shaped push rod 40 and the first pull rod 41, each strip slide bar 42 is slidably connected to a guide rail, so that the two strip slide bars 42 rise a certain distance. It should be noted that the highest point of this distance rise must be lower than the height of the two heat sealing plates 21, so as to ensure that the pressing roller 19 does not conflict with the heat sealing plate 21.

[0063] When the two bar slide bars 42 rise a certain distance, since the ends of the two bar slide bars 42 away from the guide rails are fixedly connected to the cross bar 43, each limit rod 44 is slidably connected to one end of the cross bar 43, and each adapter block 45 is fixedly connected to the end of a limit rod 44 away from the cross bar 43, one end of the cross bar 43 and each adapter block 45 respectively contact the two ends of a buffer spring 46, the pressing roller 19 is rotatably connected to the two adapter blocks 45 through the hinge shaft, thereby driving the pressing roller 19 to rise vertically, pressing one side of the packaging bag The outer wall of the end is pressed from bottom to top, and the buffer spring 46 makes the pressing roller 19 have a telescopic function, which can ensure that the outer wall of the pressing roller 19 is always attached to the outer wall of one end of the packaging bag and rises vertically, thereby squeezing the pesticide powder in the packaging bag, so that the pesticide powder is stored more dispersedly inside the packaging bag, to prevent the subsequent accumulation of concentrated particles in a certain position in the packaging bag to form lumps that affect use, and at the same time, the remaining air in the bag can be discharged before sealing to prevent the subsequent storage from being damp and resulting in reduced efficacy, thereby improving the packaging quality of the pesticide powder.

[0064] When the L-shaped push rod 40 drives the buffer frame 20 and the pressing roller 19 thereon to rise vertically to press the packaging bag, since the L-shaped push rod 40 is fixedly connected to the first rack 47 through the connecting block 49, the first gear 48 is fixedly connected to the first rotating shaft, the first rotating shaft is rotatably connected to the cross plate, and the first gear 48 is meshed with the first rack 47, so that when the first rack 47 follows the L-shaped push rod 40 to rise vertically, the first gear 48 and the first rotating shaft are driven to rotate clockwise. Since the second gear 50 is fixedly connected to the first rotating shaft, the third gear 51 and the fourth gear 52 are fixedly connected to the second rotating shaft and the third rotating shaft respectively, the second gear 50, the third gear 51 and the fourth gear 52 are meshed in sequence, the diameter of the second gear 50 is half of the diameter of the third gear 51, and the diameters of the third gear 51 and the fourth gear 52 are the same, the two synchronous wheels 54 are fixedly connected to the third rotating shaft and the fourth rotating shaft respectively, and the two synchronous wheels 54 are sleeved by the synchronous belt 53, so that the fourth rotating shaft rotates half a circle clockwise.

[0065] When the fourth shaft rotates half a circle clockwise, since the fifth gear 55 is fixedly connected to the end of the fourth shaft away from the cross plate, the second rack 56 is slidably connected to the support plate through a T-shaped slider, the second rack 56 is meshed with the fifth gear 55, the second pull rod 58 is fixedly connected to one end of the second rack 56, the hinge block 57 is fixedly connected to the end of the second pull rod 58 away from the second rack 56, the top end of the hinge block 57 and the side wall of one of the mounting rods 24 are hinged to the two ends of each connecting rod 59 respectively, so that when the second rack 56 slides at the bottom of the support plate to the end away from the support plate, it drives the two connecting rods 59 to approach each other, thereby pulling the two mounting rods 24 to approach each other, and then driving the two heat sealing plates 21 to synchronously heat press the bag mouth of the packaging bag through the four slides 23, that is, the packaging bag is sealed synchronously while the pressing roller 19 presses the packaging bag.

[0066] When a pesticide powder packaging bag is filled with powder and sealed, the screw slide 60 is started. The screw slide 60 drives the packaging bags at the bottom and the top to slide a certain distance toward one end close to the four first electric suction cups 12 through the driving block 61 and the two slide columns 62, so that the pushing component can push the next packaging bag to the bag-moving mechanism.

[0067] A number of baffle bars 65 are installed at equal intervals on the top and bottom outer walls of the side panels 64. An insertion gap is provided between every two baffle bars 65 on the top and bottom outer walls to facilitate the insertion of packaging bags. The bottom plate 63 supports the bottom of the packaging bag to prevent the packaging bag from falling. In conjunction with the screw slide 60, automatic gripping of the packaging bag can be achieved. The avoidance groove 66 provides an avoidance space for the connecting rod 26 when the bottom plate 63 drives the side panel 64 to slide toward one end close to the four first electric suction cups 12, thereby preventing the side panel 64 from conflicting with the connecting rod 26.
