Description

Technical Field

[0001] This invention relates to the field of solid pesticide filling technology, and more particularly to a solid pesticide filling device. Background Technology

[0002] Filling is a crucial step in the production of solid pesticides. Currently, existing solid pesticide filling equipment has many problems.

[0003] On the one hand, in terms of product transportation, to avoid products tilting due to gaps when transporting between two conveyor belts, integrated conveyor belts are often used, connecting multiple processing steps in series with one conveyor belt. However, this design makes the processing line cumbersome and the entire device difficult to disassemble, lacking flexibility and unable to adapt to the filling needs of different types of products, 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 inside the filling bottle, resulting in internal cavities that affect product quality and production efficiency. Furthermore, during pre-filling preparation, tiny water droplets may remain on the inner wall of the bottle; if not cleaned and dried, this can affect the storage quality of solid pesticides and potentially lead to clumping. In addition, solid pesticides in the storage tank are also prone to clumping during prolonged storage, affecting the smoothness and accuracy of filling. Most existing filling devices lack the design and functionality to effectively address these problems, making it difficult to meet the demands of modern production for efficient and high-quality filling.

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

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a solid pesticide filling device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A solid pesticide filling device includes a frame, a conveyor belt disposed within the frame, and multiple positioning components mounted on the conveyor belt.

[0009] The positioning component includes a rotary drive, a fixed end of which is fixed to the conveyor belt, and a support plate fixed to the output end of the rotary drive. A hinge plate is hinged to the side wall of the support plate, and the support plate and the hinge plate form a circular whole. An adjusting ring is fixed above the hinge plate. The adjusting ring is the same size as the circular whole and is located directly above the support plate and the hinge plate. The angle between the adjusting ring and the support plate is adjusted by a telescopic drive. An annular groove is opened on the end face of the adjusting ring away from the support plate. Several adjusting rollers are arranged in an array through the inner wall of the annular groove inside the adjusting ring. The adjusting rollers are rotatably connected to the outer walls of the annular grooves on both sides. Filling bottles are placed on the adjusting rollers.

[0010] The top of the frame has a mounting hole, and a sliding seat is fixed in the mounting hole by bolts. A mounting plate is connected to the sliding seat by a linear drive. A storage tank is fixedly connected to the mounting plate. The top of the storage tank is equipped with a feed pipe that communicates with its interior. The bottom of the storage tank has a discharge port. A control valve is installed in the discharge port to control the flow of pesticide from the discharge port. An adjusting cover is fixed on the outer wall of the storage tank outside the discharge port. The adjusting cover is adapted to the size of the adjusting ring. Two adjusting rods are fixed symmetrically at the end of the adjusting cover away from the storage tank. The adjusting rods correspond to the annular groove. When filling the bottle, the adjusting rods rotate within the annular groove.

[0011] Furthermore, a wiping assembly is provided on the mounting plate. The wiping assembly includes a fixing plate, which is fixedly installed between the inner walls of both sides of the frame. The top of the fixing plate is rotatably connected to the top of the frame via a reciprocating screw. An upper block is threaded onto the reciprocating screw, forming a reciprocating motion mechanism.

[0012] Furthermore, a mounting bracket is fixedly installed on the top of the mounting plate, and a drive motor is fixedly installed on the top of the mounting bracket. The upper end of the reciprocating lead screw passes through the top of the frame and the mounting bracket in sequence, and is fixedly connected to the output shaft of the drive motor to realize power transmission. Two lower linkage rods are slidably connected to the fixed plate. One end of each of the two lower linkage rods is fixedly connected to the bottom of the upper block, and the other end of the two lower linkage rods is fixedly installed on the same lower block, forming a vertical reciprocating motion structure.

[0013] Furthermore, a rotating cylinder is rotatably connected to the lower block, and two wiping blocks are fixedly connected to the outer side of the rotating cylinder. The wiping blocks are periodically raised and lowered to wipe by the rotation of the reciprocating screw.

[0014] Furthermore, an air blowing assembly connected to the wiping assembly is provided above the conveyor belt. The air blowing assembly includes an air storage box, which is located on the outer wall of the rotating drum and above the wiping block. A third piston is provided inside the rotating drum, which is fixedly connected to the extension end of the reciprocating screw and performs vertical reciprocating motion inside the rotating drum as the reciprocating screw rotates.

[0015] Furthermore, the rotating drum is equipped with a second mounting pipe and a third mounting pipe that are connected to its interior. Both the second and third mounting pipes are equipped with one-way valves. The end of the third mounting pipe away from the rotating drum is connected to the gas storage tank. The ends of the second and third mounting pipes that are connected to the rotating drum are located below the third piston. The third piston rotates with the reciprocating screw and slides up and down inside the rotating drum. Through the control of the one-way valve, the gas can enter and exit in one direction.

[0016] Furthermore, two limiting components connected to the wiping assembly are provided above the conveyor belt. The limiting components are fixedly installed on the fixed block at the bottom of the lower block. Two telescopic rods are fixedly installed on the inner wall of the frame. Connecting blocks are fixedly installed at the telescopic ends of the two telescopic rods. Tension springs are fixedly connected between the two connecting blocks and the inner wall of the frame. A moving block is fixedly installed between the two connecting blocks. A stop block is fixedly installed at the bottom of the moving block. The vertical cross-section of the moving block and the fixed block are both right-angled trapezoidal shapes.

[0017] Furthermore, the medicine storage tank is equipped with an agitation component connected to the wiping assembly. The agitation component includes a hollow shaft that passes through and is rotatably connected to the top of the medicine storage tank. A first transmission wheel located above the medicine storage tank is fixedly installed on the outer wall of the hollow shaft. A second transmission wheel is fixedly installed on the outer wall of the reciprocating screw. A belt is provided between the first and second transmission wheels. An agitation shaft that is slidably connected to the bottom of the hollow shaft is provided through it. An agitation rod located below the hollow shaft is fixedly installed on the outer wall of the agitation shaft. A second piston that is slidably connected to the inner wall of the hollow shaft is fixedly installed at one end of the agitation shaft. A fourth mounting tube that communicates with the interior of the hollow shaft is provided at the top of the hollow shaft.

[0018] Furthermore, a cylinder is fixedly installed on the top of the frame, and an upper linkage rod is slidably connected to the top of the mounting plate. One end of the upper linkage rod is fixedly connected to the top of the upper block, and the other end of the upper linkage rod is fixedly installed with a first piston that is slidably connected to the inner wall of the cylinder. A first mounting tube is provided on the cylinder and communicates with its interior. The end of the first mounting tube that communicates with the cylinder is located above the first piston. A rotary joint is provided between the end of the first mounting tube away from the cylinder and the end of the fourth mounting tube. The cross-sections of the second piston and the third piston are both square.

[0019] The beneficial effects of this invention are:

[0020] After the drive motor is started, the wiping block automatically rotates and wipes the inner wall of the pressed filling bottle, thereby wiping away the fine water droplets on the inner wall of the filling bottle and improving the subsequent filling effect.

[0021] During the time interval between the wiping block's movement into the filling bottle, the abutment block automatically presses against the pre-dried filling bottle to prevent shaking or displacement during subsequent processing, thus improving the subsequent drying effect.

[0022] During wiping, the wiping action can be converted into gas source productivity through the third piston. When the wiping block moves down to wipe the bottle, the third piston is drawn up, which in turn draws air into the gas storage tank for storage. When the wiping block moves up to reset, the third piston is pressed down, which in turn sprays the stored gas onto the bottle wall to enhance drying.

[0023] At the same time, the rotation and up-and-down movement of the wiping component cause the stirring rod to rotate and crush the pesticide lumps, while the up-and-down movement expands the stirring range, thereby stirring the powdered solid pesticide in the storage tank to prevent clumping.

[0024] Before the drive motor starts, the first and second conductive blocks come into contact and generate a control signal. When the drying is completed and the block rises to the top, the power supply to the conveyor belt is turned on, and the new bottle is sent into the work station. After the drying drive motor starts, the block begins to descend and disengage, the power is cut off and the conveyor stops, ensuring that the bottle is stationary. This achieves the effect of "resetting and sending the bottle, locking it when it is in place".

[0025] This invention effectively solves the problem of product tilting caused by gaps between two conveyor belts through a unique positioning component design. The rotating drive, support plate, hinge plate, and adjusting ring in the positioning component work together to maintain the adjusting ring's horizontal position when the positioning component tilts during switching between the conveying and circulating areas. This ensures the stability of the filled bottles during transport, prevents them from shifting or tilting, and guarantees smooth production.

[0026] During the filling process, a rotary drive rotates the support plate and adjusting ring. The adjusting rod slides relative to the adjusting roller within the annular groove, generating friction that causes the adjusting roller to rotate. Since the rotation direction of the adjusting rollers at both ends is towards the center of the adjusting ring, the filling bottle, under the frictional force generated by its contact with the adjusting roller, moves towards the center of the adjusting ring. This prevents solid pesticides from accumulating on one side, effectively solving the problems of uneven filling and internal cavities, and improving product quality and consistency.

[0040] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0041] Example 1:

[0042] Reference Figures 1-11 A solid pesticide filling device, comprising a frame 1;

[0043] like Figure 1 As shown, a conveyor belt 16 is provided inside 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 and are used to carry the filling bottles 18, which are used to contain solid pesticides.

[0044] It also includes a work platform 19, on which the frame 1 is slidably connected and moved back and forth on the work platform 19 by a linear drive.

[0045] Existing equipment often uses integrated conveyor belts to connect multiple processing steps, as gaps between conveyor belts can cause product tilting during transport. This results in cumbersome processing lines and difficult disassembly. This new equipment separates the filling unit from other process equipment, making it suitable for filling various types of products. Specifically, it addresses the issue of tilting caused by gaps between conveyor belts.

[0046] like Figures 2-4As shown, the positioning component 17 of this device includes a rotary drive 171. The fixed end of the rotary drive 171 is fixed to the conveyor belt 16, and the output end of the rotary drive 171 is fixed to a support plate 172. 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. 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 a telescopic drive. An annular groove 175 is opened on the end face of the adjusting ring 174 away from the support plate 172. Several adjusting rollers 176 are arranged in an array through 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. A filling bottle 18 is placed on the adjusting roller 176 for adjusting the position of the filling bottle. The conveyor belt 16 is used to transport the filling bottles 18 so that they pass through different processing stations in sequence; the positioning component 17 can support the filling bottles 18 to prevent them from shifting during the transport process.

[0047] During the filling process of solid pesticides, the movement of the conveyor belt 16 drives the movement of the positioning component 17. Since the conveyor belt 16 is a circulating conveyor belt, it is divided into a conveying area and a circulating area. The positioning component 17 in the conveying area is used to receive the empty filling bottles 18 from the previous process and transport the empty filling bottles 18 to the filling position. After filling is completed, the filling bottles 18 filled with solid pesticides are transported to the next process and then enter the circulating area to receive the empty filling bottles 18 from the previous process again.

[0048] When the positioning component 17 switches between the conveying area and the circulation area, the rotation drive 171 is fixed to the conveyor belt 16, causing the positioning component 17 to tilt. At this time, the angle between the support plate 172 and the adjusting ring 174 is adjusted to make the adjusting ring 174 horizontal. The adjusting ring 174 is brought into contact with the conveyor belt to be docked by the sliding frame 1, thereby receiving the empty filling bottle 18.

[0049] The conveyor belt 16 continues to operate, and drives the positioning component 17, which carries the empty filling bottle 18, to the filling area.

[0050] like Figures 5-7As shown, the top of the frame 1 has a mounting hole 101. 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. A pesticide storage tank 9 is embedded in the mounting plate 103 and fixedly connected thereto. The top of the pesticide storage tank 9 is provided with a feed pipe 5 that communicates with its interior. The bottom of the pesticide storage tank 9 has a discharge port 91. A control valve 36 is provided in the discharge port 91, which can control the pesticide discharge. The filling operation is carried out by the outlet 91. An adjusting cover 92 is fixed on the outer wall of the medicine storage tank 9 outside the outlet 91. The adjusting cover 92 is adapted to the size of the adjusting ring 174. Two adjusting rods 93 are fixed on the end of the adjusting cover 92 away from the medicine storage tank 9 based on central symmetry. The axis of the two adjusting rods 93 is on the same horizontal plane as the axis of the adjusting cover 92. The adjusting rods 93 correspond to the annular groove 175. When filling the filling bottle 18, the adjusting rods 93 rotate in the annular groove 175.

[0051] When the positioning assembly 17 carrying the empty filling bottle 18 reaches directly below the outlet 91, the outlet 91 and the adjusting cover 92 move downwards by sliding the mounting plate 103 downwards. The mounting plate 103 stops moving when the adjusting rod 93 enters the annular groove 175 and its bottom end face contacts the cylindrical surface of the adjusting roller 176 located within the annular groove 175. The pesticide flows out of the outlet 91 for filling via the control valve 36. During filling, the rotation drive 171 rotates the support plate 172, the adjusting cover 92, and the adjusting ring 174, while the adjusting rod 93 slides relative to the other component within the annular groove 175. During the sliding of the adjusting rod 93, the direction of the friction between the bottom end face of the adjusting rod 93 and the cylindrical surface of the adjusting roller 176 is the same as the tangential direction of the cross-section of the adjusting roller 176, thus causing the adjusting roller 176 to rotate. Since the axes of the two adjusting rods 93 and the axis of the adjusting cover 92 are on the same horizontal plane, the axial directions of the sliding of the two adjusting rods 93 are different during the rotation of the adjusting cover 92. The adjusting roller 176 is evenly divided into two parts according to the sliding trajectory of the two adjusting rods 93. The two parts of the adjusting roller 176 rotate in opposite directions. By controlling the rotation direction of the rotation drive 171, the rotation direction of both parts of the adjusting roller 176 is made towards the middle adjusting roller 176. Because the filling bottle 18 generates friction in contact with the adjusting roller 176, and the directions of the friction are inconsistent, in order to balance the friction, the filling bottle 18 moves towards the center of the adjusting ring 174, preventing the solid pesticide from accumulating on one side during filling, thus avoiding uneven filling and internal cavities. Simultaneously, during filling, the adjusting cover 92 prevents pesticide powder from splashing into the surrounding environment, providing a certain degree of protection. After filling is completed, the discharge port 91 and the adjusting cover 92 are raised and reset by sliding the mounting plate 103 upwards. At this moment, the rotary drive 171 rotates exactly 180°, and the positioning component 17 continues to move with the conveyor belt 16, transporting the pesticide-filled bottle 18 to the next process.

[0052] When the positioning component 17 carrying the pesticide-filled bottle 18 reaches the next process docking point, since this is also the boundary between the transportation area and the circulation area, the positioning component 17 tilts. Because the positioning component 17 rotated 180° during filling, the adjusting ring 174 can still be adjusted to keep it horizontal. At this time, in order to meet the space required for the positioning component 17 to adjust from the circulation area to the transportation area, the frame 1 slides, so that the positioning component 17 carrying the pesticide-filled bottle 18 contacts the conveyor belt of the next process and transports the pesticide-filled bottle 18 to the next process.

[0053] like Figure 8As shown, a wiping assembly is provided on the mounting plate 103. The wiping assembly includes a fixing plate 26, which is fixedly installed between the inner walls of both sides of the frame 1. The top of the fixing plate 26 is rotatably connected to the top of the frame through a reciprocating screw 29. An upper block 28 is threadedly connected to the reciprocating screw 29, forming a reciprocating motion mechanism.

[0054] like Figure 5 and Figure 9 As shown, a mounting bracket 3 is fixedly mounted on the top of the mounting plate 103, and a drive motor 4 is fixedly mounted on the top of the mounting bracket 3. The upper end of the reciprocating lead screw 29 passes through the top of the frame and the mounting bracket 3 in sequence, and is fixedly connected to the output shaft of the drive motor 4 to realize power transmission. Two lower linkage rods 30 are slidably connected to the fixed plate 26. One end of each of the two lower linkage rods 30 is fixedly connected to the bottom of the upper block 28, and the other end of the two lower linkage rods 30 is fixedly mounted to the same lower block 25, forming a reciprocating motion structure in the vertical direction.

[0055] A rotating cylinder 21 is rotatably connected to the lower block 25. Two wiping blocks 27 are fixedly connected to the outer side of the rotating cylinder 21. The wiping blocks 27 are periodically raised and lowered by the rotation drive of the reciprocating screw 29.

[0056] An air blowing assembly connected to the wiping assembly is provided above the conveyor belt 16. The air blowing assembly includes an air storage box 22, which is located on the outer wall of the rotating drum 21 and 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 extension end of the reciprocating screw 29 and performs vertical reciprocating motion inside the rotating drum 21 as the reciprocating screw 29 rotates.

[0057] The rotating drum 21 is provided with a second mounting pipe 20 and a third mounting pipe 38 that are connected to its interior. Both the second mounting pipe 20 and the third mounting pipe 38 are equipped with a one-way valve. The end of the third mounting pipe 38 away from the rotating drum 21 is connected to the gas storage tank 22. The ends of the second mounting pipe 20 and the third mounting pipe 38 that are connected to the rotating drum 21 are located below the third piston 37. The third piston 37 rotates with the reciprocating screw 29 and slides up and down inside the rotating drum 21. Through the control of the one-way valve, the gas can enter and exit in one direction.

[0058] Furthermore, a drying machine is installed next to the air storage tank 22. The drying machine is equipped with heating elements 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 tank for storage through the pipeline system.

[0059] like Figure 8 and Figure 10As shown, two limiting components connected to the wiping assembly are provided above the conveyor belt 16. The limiting components are fixedly installed on the fixing block 14 at the bottom of the lower block 25. Two telescopic rods 12 are fixedly installed on the inner wall of the frame 1. Connecting blocks 24 are fixedly installed at the telescopic ends of the two telescopic rods 12. 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 installed between the two connecting blocks 24. A stop block 15 is fixedly installed at the bottom of the moving block 39. The vertical cross-section of the moving block 39 and the fixing block 14 are both right-angled trapezoidal shapes.

[0060] 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, causing the two telescopic rods 12 to extend and the tension spring 13 to be stretched, thereby causing the two abutment blocks 15 to move closer to each other and press against the filling bottle 18 to prevent the filling bottle 18 from shifting or shaking during the drying process; when the lower block 25 moves upward, the fixed block 14 and the moving block 39 will no longer cooperate, and the tension spring 13 will cause the two abutment blocks 15 to move away from each other, without affecting the subsequent conveying of the filling bottle 18.

[0061] The medicine storage tank 9 is equipped with an agitation component connected to the wiping assembly. The agitation component includes a hollow shaft 23 that passes through the top of the medicine storage tank 9 and is rotatably connected thereto. A first transmission wheel 8 located above the medicine storage tank 9 is fixedly installed on the outer wall of the hollow shaft 23. A second transmission wheel 11 is fixedly installed on the outer wall of the reciprocating screw 29. A belt 10 is provided between the first transmission wheel 8 and the second transmission wheel 11. An agitation shaft 34 that is slidably connected to the bottom of the hollow shaft 23 is provided through it. An agitation rod 35 located below the hollow shaft 23 is fixedly installed on the outer wall of the agitation shaft 34. A second piston 33 that is slidably connected to the inner wall of the hollow shaft 23 is fixedly installed at one end of the agitation shaft 34. A fourth mounting tube 40 that communicates with the interior of the hollow shaft 23 is provided at the top of the hollow shaft 23.

[0062] A cylinder 2 is fixedly installed on the top of the frame 1. An upper linkage rod 32 is slidably connected to 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. A first piston 31 is fixedly installed on the other end of the upper linkage rod 32 and slidably connected to the inner wall of the cylinder 2. A first mounting tube 6 is provided on the cylinder 2 and communicates with its interior. The end of the first mounting tube 6 that communicates with 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 the end of the fourth mounting tube 40. The cross-sections of the second piston 33 and the third piston 37 are both square.

[0063] When the reciprocating screw 29 rotates, it drives the hollow shaft 23 to rotate via the first transmission wheel 8, the second transmission wheel 11, and the belt 10. This, in turn, causes the stirring shaft 34 and the stirring rod 35 to rotate, stirring the solid pesticide in the storage tank 9 to prevent clumping. At the same time, the upper block 28 moves up and down, causing the upper linkage rod 32 and the first piston 31 to slide up and down inside the cylinder 2. This allows the incompressible liquid to flow through the cylinder 2, the first mounting pipe 6, the fourth mounting pipe 40, and the hollow shaft 23, achieving hydraulic transmission. This causes the second piston 33 to slide up and down inside the hollow shaft 23, which in turn drives the stirring shaft 34 and the stirring rod 35 to move up and down, improving the stirring effect. The second piston 33 and the third piston 37, which have a square cross-section, can rotate with the hollow shaft 23 and the reciprocating screw 29, respectively.

[0064] In use, the filling bottle 18 is placed inside the positioning assembly 17 on the conveyor belt 16. Powdered solid pesticide is added to the storage tank 9 through the feed pipe 5, and then the conveyor belt 16 moves one filling bottle 18 directly below the rotating drum 21. The drive motor 4 is started, driving the reciprocating screw 29 to rotate. The reciprocating screw 29, through the transmission of the first transmission wheel 8, the second transmission wheel 11, and the belt 10, causes the hollow shaft 23 to rotate. Because 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 agitator shaft 34, and the agitator rod 35 rotate accordingly, agitating the powdered solid pesticide in the storage tank 9 to prevent clumping.

[0065] When the reciprocating screw 29 rotates, the upper block 28, being threadedly connected to the reciprocating screw 29 and guided by the two lower linkage rods 30, drives the lower block 25, the rotating cylinder 21, and the fixed block 14 to reciprocate up and down. During the reciprocating motion of the upper block 28, the first piston 31 slides back and forth inside the cylinder 2 via the upper linkage rod 32, enabling the flow of incompressible liquid in the area above the first piston 31 inside the cylinder 2, inside the first mounting tube 6, inside the fourth mounting tube 40, and in the area above the second piston 33 inside the hollow shaft 23, forming a hydraulic transmission. This causes the second piston 33 to reciprocate up and down, thereby driving the stirring shaft 34 and the stirring rod 35 to reciprocate up and down, improving the stirring effect.

[0066] When the reciprocating screw 29 rotates, the square-section third piston 37 rotates accordingly. Because the third piston 37 is slidably connected to the inner wall of the rotating cylinder 21, the rotating cylinder 21 and the wiping block 27 also rotate. During the downward movement of the lower block 25, the rotating cylinder 21, and the fixed block 14 until the wiping block 27 enters the filling bottle 18, the inclined surface of the fixed block 14 contacts the inclined surface of the moving block 39, causing the two telescopic rods 12 to extend and the tension spring 13 to be stretched. The two abutment blocks 15 move closer to each other and press against the filling bottle 18 to prevent displacement and shaking during subsequent drying. Subsequently, the rotating wiping block 27 contacts the inner wall of the filling bottle 18, cleaning the fine water droplets on the inner wall. When the rotating cylinder 21 moves downward, the third piston 37 slides upward inside the rotating cylinder 21, generating a suction effect, drawing the hot air in the gas storage box 22 into the rotating cylinder 21 through the third mounting pipe 38.

[0067] When the lower block 25, rotating drum 21, and fixed block 14 move upward, the inclined surface of the fixed block 14 no longer engages with the inclined surface of the moving block 39. The tension spring 13 keeps the two abutment blocks 15 away from each other, preventing them from affecting the subsequent conveying of the filling bottle 18. When the rotating drum 21 moves upward, the third piston 37 slides downward inside the rotating drum 21, generating a squeezing action that blows the hot air inside the rotating drum 21 through the second mounting pipe 20 onto the inner wall of the filling bottle 18, completing the drying process. Afterward, the filling bottle 18 is moved to directly below the medicine storage tank 9 by the conveyor belt 16, and filling is performed by the control valve 36. When the filling bottle 18 is directly below the medicine storage tank 9, another filling bottle 18 has moved to directly below the rotating drum 21, ready for subsequent wiping.

[0068] Example 2:

[0069] The first conductive block 41 is fixedly installed on the side wall of the upper block 28, and performs vertical reciprocating motion driven by the reciprocating screw 29.

[0070] The second conductive block 42 is fixedly installed at the bottom of the mounting plate 103, located at the highest point of the movement path of the upper block 28.

[0071] Contact conduction: When the upper block 28 rises to the highest point, the first conductive block 41 and the second conductive block 42 come into contact, forming a closed circuit, and the conveyor belt 16 is powered on and started.

[0072] Separation and power failure: When the upper block 28 moves downward to the working position (wiping block 27 enters the filling bottle 18), the two conductive blocks separate, the circuit is broken, and the power source of the conveyor belt 16 is cut off and stops.

[0073] Process operation steps: The workstation actions strictly follow the process cycle of "conveying → positioning → drying → conveying → filling".

[0074] The specific operating steps are as follows:

[0075] Step 1: Bottle Transfer

[0076] After the drive motor 4 starts, the upper block 28 begins to reciprocate. When the upper block 28 rises to the highest point, the conductive block contacts, the drive source of the conveyor belt 16 is energized, and the filling bottle 18 in the positioning component 17 is conveyed forward a 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.

[0077] Step 2: Drying stage

[0078] The upper block 28 descends, the conductive block separates, and the conveyor belt 16 is de-energized 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, while the hot air blowing mechanism starts to complete the drying.

[0079] Step 3: Filling Stage

[0080] After drying is complete, the conveyor belt 16 is powered on again, sending the dried bottle directly below the medicine storage tank 9, and the control valve 36 is opened for filling; the next bottle enters the drying station simultaneously, and the process is repeated.
