Description

Technical Field

[0001] The present invention relates to the technical field of solid pesticide filling, in particular to a solid pesticide filling device. Background Art

[0002] In the production process of solid pesticides, filling is one of the key links. At present, there are many problems in the existing solid pesticide filling devices.

[0003] On the one hand, to prevent product tilting due to gaps between two conveyor belts, a single-piece conveyor belt is often used, connecting multiple processing steps in series. However, this design occupies a large space in the processing line, and the entire device is difficult to disassemble, lacking flexibility, making it difficult to adapt to the filling needs of different product types and unable to flexibly adjust and optimize the layout according to actual production conditions.

[0004] On the other hand, during the filling process, solid pesticides tend to accumulate unevenly in the filling bottle, resulting in internal cavities, which affects product quality and production efficiency. Also, during the preparations before filling, tiny water droplets may form on the inner wall of the filling bottle. If not cleaned and dried, this can affect the storage quality of the solid pesticide and may cause problems such as pesticide clumping. Furthermore, solid pesticides in storage boxes are prone to clumping during long-term storage, affecting the smoothness and accuracy of filling. Most existing filling devices lack the design and functionality to effectively address these issues, making it difficult to meet the requirements of modern production for efficient, high-quality filling.

[0005] A solid pesticide filling device is proposed to solve the problems of easy tilting and uneven filling of current equipment products. Summary of the Invention

[0019] The beneficial effects of the present application are as follows:

[0020] After the driving motor is started, the wiping block automatically rotates and wipes the inner wall of the tightly pressed filling bottle, so that the fine water droplets on the inner wall of the filling bottle are wiped off, and the subsequent filling effect is improved.

[0021] During the time interval when the wiping block moves downward into the filling bottle, the resisting block automatically presses the pre-dried filling bottle, so that shaking or deviation of the filling bottle in the subsequent processing process is avoided, and the subsequent drying effect is improved.

[0022] When wiping, the third piston can convert the wiping action into gas source productivity. When the wiping block moves down to wipe the bottle, the third piston is pumped up, and the air is sucked into the air storage box for storage. When the wiping block moves up and resets, the third piston is pressed down, and the stored gas is sprayed onto the bottle wall to enhance drying.

[0023] At the same time, the rotation and up and down movement of the wiping component causes the stirring rod to rotate and crush the medicine blocks, while the up and down movement expands the stirring range, thereby stirring the powdered solid pesticide in the medicine storage box up and down to avoid agglomeration.

[0024] Before the drive motor is started, the first conductive block and the second conductive block will contact to generate a control signal, which can turn on the power of the conveyor belt when it rises to the top after drying, and deliver the new bottle to the work station. After the drying starts, the drive motor starts, and begins to descend and disengage, and the power is cut off to stop the conveying, ensuring that the bottle body is stationary, thereby achieving the effect of "reset to send the bottle, and lock it when it is in place".

[0025] The present invention effectively solves the problem of product tilting caused by the gap between the two conveyor belts through the unique positioning assembly design. The rotary drive, support plate, hinge plate, and adjustment ring in the positioning assembly work together to ensure that when the positioning assembly tilts when switching between the conveying area and the circulation area, the angle between the support plate and the adjustment ring is adjusted to keep the adjustment ring horizontal. This ensures the stability of the filled bottles during the conveying process, prevents them from shifting and tilting, and ensures smooth production.

[0026] During the filling process, the rotary drive drives the support plate and adjustment ring, causing the adjustment rod to slide relative to the annular groove, generating friction with the adjustment roller, causing the adjustment roller to rotate. Because the adjustment rollers at both ends rotate toward the center of the adjustment ring, the friction generated by contact with the adjustment rollers causes the filled bottle to move toward the center of the adjustment ring, preventing solid pesticide from accumulating on only one side. This effectively solves the problems of uneven filling and internal cavities, and improves product quality and consistency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following is a non-limiting detailed description of the technical solutions of the present invention in conjunction with preferred embodiments and the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0030] Example 1:

[0031] Reference Figures 1-11 , a solid pesticide filling device, comprising a frame 1; like Figure 1 As shown, a conveyor belt 16 is provided in the frame 1, and a plurality of positioning components 17 are provided on the conveyor belt 16. The positioning components 17 are arranged along the conveying path of the conveyor belt 16. The positioning components 17 are used to carry filling bottles 18, and the filling bottles 18 are used to contain solid pesticides.

[0032] It also includes a working platform 19, and the frame 1 is slidably connected to the working platform 19 and is moved back and forth on the working platform 19 by linear driving.

[0033] Existing devices often use integrated conveyors, considering that gaps between conveyors can cause products to tilt when transported between two conveyors. Multiple processing steps are connected in series on a single conveyor, resulting in cumbersome processing line space and difficulty in disassembling the device. This device separates the filling device from the devices used in other processes, making it suitable for filling various types of products. Specifically, to address the problem of tilting caused by analysis between the two conveyors; like Figure 2-Figure 4 As shown, the positioning assembly 17 of the present device includes a rotary drive 171, the fixed end of the rotary drive 171 is fixed to the conveyor belt 16, and a support plate 172 is fixed to the output end of the rotary drive 171, and a hinge plate 173 is hinged to the side wall of the support plate 172. The support plate 172 and the hinge plate 173 form a circular whole, and an adjusting ring 174 is fixed above the hinge plate 173. The adjusting ring 174 is the same size as the circular whole and is located directly above the support plate 172 and the hinge plate 173. The angle between the adjusting ring 174 and the support plate 172 is adjusted by telescopic drive. An annular groove 175 is provided on the end surface of the adjusting ring 174 away from the support plate 172. A plurality of adjusting rollers 176 are arranged in an array on the inner wall of the annular groove 175 in the adjusting ring 174. The adjusting rollers 176 are rotatably connected to the outer walls of the annular grooves 175 on both sides, and the filling bottles 18 are placed on the adjusting rollers 176 for adjusting the position of the filling bottles. The conveyor belt 16 is used to transport the filled bottles 18 so that they pass through different processing stations in sequence; the positioning assembly 17 can carry the filled bottles 18 to prevent them from shifting during the conveying process.

[0034] During the filling process of solid pesticides, the operation of the conveyor belt 16 drives the movement of the positioning assembly 17. Since the conveyor belt 16 is a circulating conveyor belt, it is divided into a conveying area and a circulation area. The positioning assembly 17 in the conveying area is used to receive the empty filling bottles 18 conveyed from the previous process and transport the empty filling bottles 18 to the filling position. After the filling is completed, the filling bottles 18 filled with solid pesticides are transported to the next process, and then enter the circulation area to receive the empty filling bottles 18 conveyed from the previous process again.

[0035] When the positioning assembly 17 switches between the conveying area and the circulation area, the rotation drive 171 is fixed to the conveyor belt 16, thereby causing the positioning assembly 17 to tilt. At this time, the adjustment ring 174 is adjusted to a horizontal state by adjusting the angle between the support plate 172 and the adjustment ring 174. The adjustment ring 174 is brought into contact with the conveyor belt to be docked by sliding the frame 1, thereby receiving the empty filling bottle 18.

[0036] The conveyor belt 16 continues to work and drives the positioning assembly 17 carrying the empty filling bottles 18 to the filling area.

[0037] like Figure 5-Figure 7 As shown, a mounting hole 101 is provided on the top of the frame 1, a sliding seat 102 is fixed in the mounting hole 101 by bolts, a mounting plate 103 is connected to the sliding seat 102 by a linear drive, and the mounting plate 103 is embedded with a medicine storage box 9 fixedly connected thereto, a feed pipe 5 is provided on the top of the medicine storage box 9 and connected to the inside thereof, a discharge port 91 is provided at the bottom of the medicine storage box 9, a control valve 36 is provided in the discharge port 91, and the control valve 36 can control the pesticide from the discharge port The filling operation is carried out through the outlet 91. An adjusting cover 92 is fixed on the outer wall of the medicine storage box 9 outside the discharge port 91. The adjusting cover 92 is adapted to the size of the adjusting ring 174. Two adjusting rods 93 are fixed to the end of the adjusting cover 92 away from the medicine storage box 9 based on central symmetry, and the axes of the two adjusting rods 93 and the axes of the adjusting cover 92 are on the same horizontal plane. The adjusting rods 93 correspond to the annular groove 175. When the filling bottle 18 is filled, the adjusting rod 93 rotates in the annular groove 175.

[0038] When the positioning assembly 17, carrying the empty filling bottle 18, reaches directly below the discharge port 91, the mounting plate 103 slides downward, driving the discharge port 91 and the adjustment cover 92 downward. When the adjustment rod 93 enters the annular groove 175 and its bottom end surface contacts the cylindrical surface of the adjustment roller 176 located within the annular groove 175, the movement of the mounting plate 103 stops. The control valve 36 allows the pesticide to flow out of the discharge port 91 for filling. During the filling process, the rotary drive 171 rotates the support plate 172, the adjustment cover 92, and the adjustment ring 174, causing the adjustment rod 93 to slide relative to each other within the annular groove 175. As the adjustment rod 93 slides, the friction between the bottom end surface of the adjustment rod 93 and the cylindrical surface of the adjustment roller 176 is tangential to the cross-section of the adjustment roller 176, driving the adjustment roller 176 to rotate. Because the axes of the two adjustment rods 93 and the axis of the adjustment cover 92 are coplanar, the two adjustment rods 93 slide in different axial directions during the rotation of the adjustment cover 92. This trajectories divide the adjustment roller 176 into two equal parts, each rotating in opposite directions. By controlling the rotation direction of the rotary drive 171, both adjustment rollers 176 rotate toward the center adjustment roller 176. Friction generated by the contact between the filling bottle 18 and the adjustment roller 176, with the frictional forces acting in different directions, causes the filling bottle 18 to move toward the center of the adjustment ring 174 to balance the frictional forces. This prevents solid pesticide from accumulating on one side during the filling process, resulting in uneven filling and the creation of internal cavities. Furthermore, during the filling process, the adjustment cover 92 prevents pesticide powder from splashing into the surrounding environment, providing a protective barrier. After filling is complete, the mounting plate 103 is slid upward, causing the discharge port 91 and the adjustment cover 92 to rise and return to their original position. At this time, the rotary drive 171 rotates exactly 180 degrees, and the positioning assembly 17 continues to move along with the conveyor belt 16 to convey the filling bottle 18 filled with pesticide to the next process.

[0039] When the positioning assembly 17 carrying the filling bottle 18 filled with pesticide reaches the docking point of the next process, the positioning assembly 17 is tilted because it is also at the junction of the transportation area and the circulation area. Since the positioning assembly 17 rotates 180° during filling, the adjustment ring 174 can still be adjusted to keep it horizontal. At this time, in order to meet the space required for adjusting the positioning assembly 17 from the circulation area to the transportation area, the frame 1 slides, so that the positioning assembly 17 carrying the filling bottle 18 filled with pesticide contacts the conveyor belt of the next process and transports the filling bottle 18 filled with pesticide to the next process.

[0040] like Figure 8As shown, a wiping assembly is provided on the mounting plate 103, and the wiping assembly includes a fixed plate 26, which is fixedly mounted between the inner walls of the frame 1 on both sides, and the top of the fixed plate 26 is rotatably connected to the top of the frame via a reciprocating screw 29. The reciprocating screw 29 is threadedly connected to an upper block 28, forming a reciprocating motion mechanism.

[0041] like Figure 5 and Figure 9 As shown, the top of the mounting plate 103 is fixedly mounted with a mounting frame 3, and the top of the mounting frame 3 is fixedly mounted with a drive motor 4. The upper end of the reciprocating screw 29 passes through the top of the frame and the mounting frame 3 in sequence, and is fixedly connected to the output shaft of the drive motor 4 to achieve power transmission. Two lower linkage rods 30 are provided through the fixed plate 26 and are slidably connected thereto. One end of each lower linkage rod 30 is fixedly connected to the bottom of the upper block 28, and the other end of each lower linkage rod 30 is fixedly mounted to the same lower block 25, forming a vertical reciprocating motion structure.

[0042] The lower block 25 is provided with a rotating drum 21 rotatably connected thereto, and two wiping blocks 27 fixedly connected thereto are provided on the outer side of the rotating drum 21 . The wiping blocks 27 are driven by the rotation of the reciprocating screw 29 to achieve periodic lifting and wiping actions.

[0043] A blowing assembly connected to the wiping assembly is provided above the conveyor belt 16, and the blowing assembly includes an air storage box 22. The air storage box 22 is provided on the outer wall of the rotating drum 21 and is located above the wiping block 27. A third piston 37 is provided inside the rotating drum 21. The third piston 37 is fixedly connected to the extended end of the reciprocating screw 29 and performs vertical reciprocating motion in the rotating drum 21 as the reciprocating screw 29 rotates.

[0044] The rotating drum 21 is provided with a second mounting tube 20 and a third mounting tube 38 connected to the interior thereof. A one-way valve is provided in the second mounting tube 20 and the third mounting tube 38. One end of the third mounting tube 38 away from the rotating drum 21 is connected to the air storage box 22. The ends of the second mounting tube 20 and the third mounting tube 38 connected to the rotating drum 21 are both located below the third piston 37. The third piston 37 rotates with the reciprocating screw 29 and slides up and down in the rotating drum 21. The one-way inlet and outlet of the gas is realized by the control of the one-way valve.

[0045] Furthermore, a drying machine is provided next to the air storage box 22. The drying machine is equipped with a heating element and an air circulation system, which can continuously generate dry air. The dry air generated by the drying machine is continuously transported to the air storage box for storage through the pipeline system.

[0046] like Figure 8 and Figure 10As shown, two limit assemblies connected to the wiping assembly are provided above the conveyor belt 16, and the limit assemblies are fixedly mounted on the fixed block 14 at the bottom of the lower block 25. Two telescopic rods 12 are fixedly mounted on the inner wall of the frame 1, and the telescopic ends of the two telescopic rods 12 are fixedly mounted with connecting blocks 24. Tension springs 13 are fixedly connected between the two connecting blocks 24 and the inner wall of the frame 1. A moving block 39 is fixedly mounted between the two connecting blocks 24, and a stop block 15 is fixedly mounted on the bottom of the moving block 39. The vertical cross-sections of the moving block 39 and the fixed block 14 are both right-angled trapezoidal shapes.

[0047] When the lower block 25 moves downward, the inclined surface of the fixed block 14 will contact the inclined surface of the moving block 39, so that the two telescopic rods 12 are extended, the tension spring 13 is extended, and the two retaining blocks 15 are brought closer to each other, pressing the filling bottles 18 tightly to prevent the filling bottles 18 from shifting and shaking during the drying process; when the lower block 25 moves upward, the fixed block 14 and the moving block 39 no longer cooperate, and the tension spring 13 makes the two retaining blocks 15 move away from each other, which does not affect the subsequent transportation of the filling bottles 18.

[0048] The medicine storage box 9 is provided with a stirring assembly connected to the wiping assembly, and the stirring assembly includes a hollow shaft 23 that is arranged on the top of the medicine storage box 9 and is rotatably connected thereto. A first transmission wheel 8 located above the medicine storage box 9 is fixedly mounted on the outer wall of the hollow shaft 23, a second transmission wheel 11 is fixedly mounted on the outer wall of the reciprocating screw rod 29, a belt 10 is arranged between the first transmission wheel 8 and the second transmission wheel 11, a stirring shaft 34 that is slidably connected to the bottom of the hollow shaft 23 is penetrated by the bottom of the hollow shaft 23, a stirring rod 35 located below the hollow shaft 23 is fixedly mounted on the outer wall of the stirring shaft 34, a second piston 33 that is slidably connected to the inner wall of the hollow shaft 23 is fixedly mounted on one end of the stirring shaft 34, and a fourth mounting tube 40 that is connected to the interior of the hollow shaft is provided on the top of the hollow shaft 23.

[0049] The cylinder 2 is fixedly mounted on the top of the frame 1, and an upper linkage rod 32 slidably connected to the cylinder 2 is provided through the top of the mounting plate 103. One end of the upper linkage rod 32 is fixedly connected to the top of the upper block 28, and the other end of the upper linkage rod 32 is fixedly mounted with a first piston 31 slidably connected to the inner wall of the cylinder 2. A first mounting tube 6 connected to the interior of the cylinder 2 is provided on the cylinder 2, and one end of the first mounting tube 6 connected to the cylinder 2 is located above the first piston 31. A rotary joint 7 is provided between the end of the first mounting tube 6 away from the cylinder 2 and one end of the fourth mounting tube 40. The cross-sections of the second piston 33 and the third piston 37 are both square.

[0050] When the reciprocating screw 29 rotates, the hollow shaft 23 is driven to rotate through the first transmission wheel 8, the second transmission wheel 11 and the belt 10, thereby rotating the stirring shaft 34 and the stirring rod 35 to stir the solid pesticide in the medicine storage box 9 to prevent agglomeration; at the same time, the upper block 28 moves up and down, driving the upper linkage rod 32 and the first piston 31 to slide up and down in the cylinder 2, so that the incompressible liquid circulates in the cylinder 2, the first mounting tube 6, the fourth mounting tube 40, and the hollow shaft 23, realizing hydraulic transmission, so that the second piston 33 slides up and down in the hollow shaft 23, thereby driving the stirring shaft 34 and the stirring rod 35 to move up and down, thereby improving the stirring effect; the second piston 33 and the third piston 37 with a square cross section can rotate with the hollow shaft 23 and the reciprocating screw 29, respectively.

[0051] When the present invention is used, the filling bottle 18 is placed in the positioning assembly 17 on the conveyor belt 16. Powdered solid pesticide is added to the medicine storage box 9 through the feed pipe 5, and then the conveyor belt 16 is used to move a filling bottle 18 to the bottom of the rotating drum 21. The drive motor 4 is started to drive the reciprocating screw 29 to rotate. The reciprocating screw 29 rotates the hollow shaft 23 through the transmission of the first transmission wheel 8, the second transmission wheel 11 and the belt 10. Since the second piston 33 has a square cross-section and is slidably connected to the inner wall of the hollow shaft 23, the second piston 33, the stirring shaft 34 and the stirring rod 35 rotate accordingly, stirring the powdered solid pesticide in the medicine storage box 9 to prevent agglomeration.

[0052] As the reciprocating screw 29 rotates, the upper block 28, threadedly connected to the reciprocating screw 29 and guided by two lower linkage rods 30, drives the lower block 25, the rotating drum 21, and the fixed block 14 to reciprocate up and down. During the reciprocating motion of the upper block 28, the upper linkage rod 32 causes the first piston 31 to slide back and forth within the cylinder 2. This allows the incompressible liquid in the area above the first piston 31 within the cylinder 2, within the first mounting tube 6, within the fourth mounting tube 40, and within the area above the second piston 33 within the hollow shaft 23 to circulate, creating a hydraulic transmission that causes the second piston 33 to reciprocate up and down, thereby driving the stirring shaft 34 and stirring rod 35 to reciprocate up and down, improving the stirring effect.

[0053] When the reciprocating screw rod 29 rotates, the third piston 37 with a square cross section rotates, and the rotary drum 21 and the wiping block 27 also rotate due to the sliding connection between the third piston 37 and the inner wall of the rotary drum 21. During the downward movement of the lower block 25, the rotary drum 21 and the fixed block 14 to the process of the wiping block 27 entering the filling bottle 18, the inclined surface of the fixed block 14 is in contact with the inclined surface of the moving block 39, so that the two telescopic rods 12 are elongated, the tension spring 13 is elongated, and the two abutting blocks 15 are close to each other and abut against the filling bottle 18 to prevent deviation and shaking during the subsequent drying process. Subsequently, the rotating wiping block 27 contacts the inner wall of the filling bottle 18 to clean the small water droplets on the inner wall. When the rotary drum 21 moves downward, the third piston 37 slides upward in the rotary drum 21, generating a suction effect to suck the hot gas in the gas storage tank 22 into the rotary drum 21 through the third installation pipe 38.

[0054] When the lower block 25, the rotary drum 21 and the fixed block 14 move upward, the inclined surface of the fixed block 14 is no longer matched with the inclined surface of the moving block 39, the tension spring 13 causes the two abutting blocks 15 to move away from each other to avoid affecting the subsequent conveying of the filling bottle 18. When the rotary drum 21 moves upward, the third piston 37 slides downward in the rotary drum 21, generating a squeezing effect to blow the hot gas in the rotary drum 21 to the inner wall of the filling bottle 18 through the second installation pipe 20, completing the drying process. Subsequently, the filling bottle 18 is moved to be directly below the medicine storage tank 9 by the conveying belt 16, and is filled by controlling the valve 36. When the filling bottle 18 is located directly below the medicine storage tank 9, another filling bottle 18 has been moved to be directly below the rotary drum 21, preparing for subsequent wiping.

[0055] Example Two:

[0056] The first conductive block 41 is fixedly arranged on the side wall of the upper block 28 and vertically reciprocates with the reciprocating screw rod 29; The second conductive block 42 is fixedly arranged at the bottom of the mounting plate 103 and located at the position corresponding to the highest point of the movement path of the upper block 28.

[0057] Contact conduction: when the upper block 28 rises to the highest point, the first conductive block 41 contacts the second conductive block 42 to form a closed circuit, and the driving source of the conveying belt 16 is powered on; Separation and power-off: when the upper block 28 moves downward to the working position (the wiping block 27 enters the filling bottle 18), the two conductive blocks are separated, the circuit is disconnected, and the driving source of the conveying belt 16 is powered off and stopped.

[0058] Process running procedure: the workstations strictly follow the "conveying → positioning → drying → conveying → filling" process cycle.

[0059] The specific running steps are as follows: Step 1: Bottle body transfer After the drive motor 4 is started, the upper block 28 begins to reciprocate; when the upper block 28 rises to the highest point, the conductive blocks are in contact, the driving source of the conveyor belt 16 is energized, and the filled bottles 18 in the positioning assembly 17 are conveyed forward a certain distance (the vertical distance between the axis of the rotating drum 21 and the axis of the medicine storage box 9), so that the next bottle to be processed enters the drying station and the dried bottle enters the filling station.

[0060] Step 2: Drying Phase The upper block 28 descends, the conductive block separates, and the conveyor belt 16 is powered off and stops; the rotating drum 21 drives the wiping block 27 to descend and rotate, cleaning the water droplets on the inner wall of the bottle, and at the same time the hot air blowing mechanism is started to complete the drying.

[0061] Step 3: Filling stage After drying is completed, the conveyor belt 16 is powered on again to deliver the drying bottle to the bottom of the medicine storage box 9, and the control valve 36 is opened for filling; the next bottle enters the drying station synchronously and the process is repeated.
