Description

Technical Field

[0001] This utility model relates to a dripping machine, specifically a switch protection device for the dripping machine, belonging to the technical field of dripping pellet equipment. Background Technology

[0002] A pharmaceutical pellet machine is a specialized piece of equipment used to produce pellet dosage forms. It integrates advanced mechanical, electrical, and automation technologies, enabling it to efficiently and stably produce pellet products that meet pharmaceutical quality standards.

[0003] A pharmaceutical pelleting machine mainly consists of a pelleting system, a heating system, a cooling system, and a control system. The pelleting system, through a precisely designed dropper, evenly drips molten medicine into a cooling medium, where it rapidly solidifies into pellets. The heating system heats the raw drug to a molten state, while the cooling system ensures that the pellets cool and solidify quickly, maintaining their shape and stability. The control system monitors and regulates the entire production process, ensuring that parameters such as dripping rate, temperature, and cooling rate remain within preset ranges, thereby guaranteeing product quality and consistency.

[0004] In existing pelletizing machines, the material being pelletized is propelled by gravity or pressure during the pelletizing process, causing it to fall evenly from inside the pellet head. The material then forms pellets on its own based on surface tension and internal stress. Although this structure can form pellets, the reliance on surface tension and internal stress for pellet formation results in insufficient roundness and significant differences in pellet size, leading to a low pass rate. To address these issues, we provide a switch protection device for the pelletizing machine. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a switch protection device for a dripping machine, the specific technical solution of which is as follows: A switch protection device for a dripping machine includes a dripping head, the bottom end of which is connected to a housing. Multiple sets of first forming clamps and second forming clamps are slidably connected to the inner wall of the housing. The inner sides of the first forming clamps and second forming clamps are provided with spherical grooves. A swing arm is provided on the outside of the housing. One end of the swing arm is hinged to a connecting rod. A hydraulic cylinder is provided above the connecting rod.

[0006] Preferably, one side of each of the first and second forming clamps is connected to a rotating shaft, the outer surface of the housing is connected to a support shaft, the inner side of the swing arm has two first slides that are symmetrical to each other, the inner wall of the first slide is slidably connected to the outer surface of the rotating shaft, and the inner wall of the swing arm is rotatably connected to the inner wall of the support shaft.

[0007] Preferably, a support base is connected to the outer surface of the housing, the fixed end of the hydraulic cylinder is connected to one side of the support base, and the output end of the hydraulic cylinder is connected to a slide.

[0008] Preferably, a second slide rail is provided on the inner side of the slide block, and a slider is slidably connected to the inner wall of the second slide rail. The inner wall of the slider is rotatably connected to the end of the connecting rod away from the swing arm.

[0009] Preferably, a spring is connected to one side of the slider, and the end of the spring away from the slider is connected to the inner wall of the second slide.

[0010] Preferably, the inner wall of the housing is provided with multiple sliding grooves, the outer surfaces of the first forming clamp and the second forming clamp are both connected with slide rails, the outer surfaces of the slide rails are slidably connected to the inner walls of the sliding grooves, and both ends of the housing can be detachably connected with cover plates.

[0011] Preferably, the number of the multiple sets of first forming clamps and second forming clamps are both two, the two first forming clamps and the two second forming clamps are arranged symmetrically, and the two first forming clamps are located above the two second forming clamps.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The switch protection device of this dripping machine, through the cooperation between the first forming clamp, the second forming clamp, and the spherical groove, receives the dripping material by merging the second forming clamp together, preventing the dripping material from continuing to fall. The spherical groove shapes the lower part of the dripping material that falls into the second forming clamp. After the second forming clamp separates, the first forming clamp merges at the same time, blocking the dripping material and preventing it from continuing to drip down from the inside of the dripping head. At the same time, it shapes the upper part of the dripping material that has dripped into the second forming clamp, improving the roundness and uniformity of the droplet size.

[0013] 2. The switch protection device of the dripping machine, through the cooperation between the slider, the spring and the second slide, allows the slider to have space to move through the second slide. When the slider slides, the spring provides elastic support and prevents damage caused by hard contact between the two first forming clamps and the two second forming clamps, thus improving the safety when the first forming clamps and the two second forming clamps come into contact with each other.

[0016] The present invention will now be further described with reference to the accompanying drawings.

[0017] Please see Figures 1-5 A switch protection device for a dripping machine includes a dripping head 1, with a housing 2 connected to the bottom end of the dripping head 1. Multiple sets of first forming clamps 3 and second forming clamps 4 are slidably connected to the inner wall of the housing 2. Each of the first forming clamps 3 and second forming clamps 4 has a spherical groove 5 on its inner side. The spherical groove 5 shapes the dripping material, molding it into a spherical shape. When the first forming clamps 3 and second forming clamps 4 are combined, they form a spherical shape internally. The two first forming clamps 3 shape the upper part of the dripping material, and the two second forming clamps 4 shape the lower part of the dripping material. The number of each set of first forming clamps 3 and second forming clamps 4 is two. The first forming clamp 3 and the two second forming clamps 4 are arranged symmetrically, with the two first forming clamps 3 located above the two second forming clamps 4. When the swing arm 6 swings, the first forming clamps 3 and the second forming clamps 4 move simultaneously through the rotating shaft 9. The first forming clamps 3 and the second forming clamps 4 move in opposite directions. The two first forming clamps 3 retract inward and together, while the two second forming clamps 4 separate in opposite directions. After the two second forming clamps 4 separate in opposite directions, the dripping material falls out from inside the spherical groove 5. After the two first forming clamps 3 merge together, they form a blockage against the dripping head 1, preventing the dripping material from dripping out from inside the outlet of the dripping head 1 and sealing the outlet of the dripping head 1.

[0018] A swing arm 6 is provided on the outside of the housing 2. A connecting rod 7 is hinged to one end of the swing arm 6. A hydraulic cylinder 8 is provided above the connecting rod 7. The hydraulic cylinder 8 is the power source to provide power for the movement of the connecting rod 7. After the connecting rod 7 moves, it pushes the swing arm 6 to move. There is an angle difference between the swing arm 6 and the hydraulic cylinder 8. The connecting rod 7 compensates for the angle difference between the swing arm 6 and the hydraulic cylinder 8. A support seat 12 is connected to the outer surface of the housing 2. The fixed end of the hydraulic cylinder 8 is connected to one side of the support seat 12. The output end of the hydraulic cylinder 8 is connected to a slide 13. The support seat 12 provides support force for the hydraulic cylinder 8 and maintains the stability of the hydraulic cylinder 8.

[0019] One side of the first forming clamp 3 and the second forming clamp 4 are both connected to a rotating shaft 9. The first forming clamp 3 and the second forming clamp 4 receive the power of the swing arm 6 through the rotating shaft 9. The outer surface of the housing 2 is connected to a support shaft 10, which provides support force to the swing arm 6 and maintains the stability of the swing arm 6 when it moves. Two first slides 11 are opened on the inner side of the swing arm 6, and the two first slides 11 are symmetrical. The inner wall of the first slide 11 is slidably connected to the outer surface of the rotating shaft 9. The inner wall of the swing arm 6 is rotatably connected to the inner wall of the support shaft 10. The first slide groove 17 provides space for the swing arm 6 to move. When the swing arm 6 moves, an angle difference will be generated between it and the rotating shaft 9. The slide groove 17 compensates for the angle difference between the swing arm 6 and the rotating shaft 9.

[0020] A second slide rail 14 is provided on the inner side of the slide block 13. A slider 15 is slidably connected to the inner wall of the second slide rail 14. The inner wall of the slider 15 is rotatably connected to the end of the connecting rod 7 away from the swing arm 6. The second slide rail 14 provides space for the slider 15 to move. At the same time, the second slide rail 14 wraps around the slider 15 to maintain the stability of the slider 15 when it moves. A spring 16 is connected to one side of the slider 15. The end of the spring 16 away from the slider 15 is connected to the inner wall of the second slide rail 14. The spring 16 provides elastic support for the slider 15 to prevent damage caused by hard contact between the two first forming clamps 3 and the two second forming clamps 4.

[0021] The inner wall of the housing 2 is provided with multiple sliding grooves 17. The outer surfaces of the first forming clamping block 3 and the second forming clamping block 4 are both connected to slide rails 18. The outer surfaces of the slide rails 18 are slidably connected to the inner walls of the sliding grooves 17. Both ends of the housing 2 can be detachably connected to cover plates 19. The sliding grooves 17 provide guidance for the slide rails 18 and maintain the stability of the slide rails 18 when they move. The slide rails 18 provide support for the first forming clamping block 3 and the second forming clamping block 4 and maintain the stability of the first forming clamping block 3 and the second forming clamping block 4 when they move.

[0022] In use, this invention works as follows: First, the hydraulic cylinder 8 is retracted. After the hydraulic cylinder 8 retracts, it moves the slide 13 upward. Simultaneously, the slider 15 moves the connecting rod 7 upward. The connecting rod 7 moves simultaneously, causing the swing arm 6 to swing left and right around the support shaft 10. As the swing arm 6 swings, the first slide rail 11 pushes the rotating shaft 9 to move. The rotating shaft 9 pushes the first forming clamp 3 and the second forming clamp 4 to move simultaneously. After the first forming clamp 3 moves, it separates from each other, while the second forming clamp 4 moves closer together. Then, the dripping material drips from the outlet of the dripping head 1 and falls into the second forming clamp 4. Then, the hydraulic cylinder 8 is activated to extend the slide. After the hydraulic cylinder 8 extends, the slide 13, slider 15, connecting rod 7, and swing arm... The material moves in six directions, and then the two first forming clamps 3 come into contact with each other and merge together, while the two second forming clamps 4 move away from each other and separate. While the two first forming clamps 3 merge together, they squeeze the dripping material. The dripping material has viscosity and will not fall off immediately after the two second forming clamps 4 separate. The two first forming clamps 3 squeeze and shear the dripping material, squeezing and separating the dripping material below the first forming clamps 3 from the dripping material inside the dripper head 1. While the two first forming clamps 3 are in contact, the upper part of the dripping material is squeezed and plasticized through the spherical groove 5, while isolating the dripping material inside the spherical groove 5 from the dripping material inside the dripper head 1. After the two second forming clamps 4 move away from each other and separate, the dripping material inside detaches from the spherical groove 5 and falls off, forming a drip pellet product.
