Description

Technical Field

[0001] This invention relates to the field of delivery devices, specifically a syringe processing and delivery device. Background Technology

[0002] The syringe manufacturing process includes injection molding, assembly, cleaning, sterilization, testing, and packaging. Efficient material flow between these stages requires a conveying system. Incorporating the design concepts and technologies of automated storage and retrieval systems (AS / RS), the conveying system should achieve high efficiency, precision, flexibility, and intelligence, significantly improving production efficiency and product quality.

[0003] In existing technology, syringes are generally first transported to a clamping device via a vibratory feeder. The clamping device, in conjunction with a cylinder, clamps and transports the syringe. The syringe can then be transferred from the clamping device to the processing station to achieve production transport of the syringe. However, during use and observation, it was found that this transport method is inconvenient because the cylinder needs to repeatedly grab the syringe, resulting in a long action cycle.

[0004] Therefore, a syringe processing and delivery device is proposed to address the above problems. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: A syringe processing and conveying device of the present invention includes a chute, one side of which is connected to the discharge port of a vibrating plate; the other side of the chute is provided with a material handling assembly and a conveying assembly; the material handling assembly includes a mounting plate; a first motor is fixedly connected inside the mounting plate; a rotating shaft is fixedly connected to the output end of the first motor; a first distributing disc is fixedly connected to the end of the rotating shaft; a second distributing disc is provided on one side of the first distributing disc, and the second distributing disc is inclined; both the surface of the first and second distributing discs are provided with grooves for limiting syringes; a first spur gear is fixedly connected to the middle of the rotating shaft, and a second spur gear is provided on one side of the first spur gear, the second spur gear being rotatably connected to the mounting plate; the first spur gear and the second spur gear are meshed; a first bevel gear is fixedly connected to the top of the second spur gear; the middle of the second distributing disc... A second bevel gear is fixedly connected to the mounting plate, and the second bevel gear meshes with the first bevel gear. A fixed plate is provided on one side of the second distribution plate, and the fixed plate is fixedly connected to the mounting plate. A baffle and a support plate are fixedly connected to the surface of the fixed plate. The baffle has an L-shaped structure, and the support plate is longer than the baffle. The conveying assembly includes a pair of frames. A pair of conveying rollers are rotatably connected between the pair of frames. A conveyor belt is sleeved on the conveying rollers, and multiple support plates are fixedly connected to the conveyor belt. The support plates are provided with slots for limiting the syringes. A second motor is fixedly connected to one side of one of the frames, and the output end of the second motor is fixedly connected to one of the conveying rollers. Through the cooperation of the first and second distribution plates, the syringes conveyed by the vibratory feeder can be orderly sorted and conveyed to the conveying assembly, realizing the rapid stacking of syringes and facilitating subsequent processing of the syringes.

[0007] Preferably, a hemisphere is fixedly connected to the middle of the rotating shaft; a sphere is provided inside the hemisphere; multiple protrusions are fixedly connected inside the hemisphere, and the protrusions are located in the upper region of the hemisphere; through the cooperation of the sphere and the protrusions, the sphere can move continuously under centrifugal force and collide with the protrusions, so that the syringe on the first dispensing plate can continuously adjust its posture under vibration, thereby reducing the jamming of the syringe when it is conveyed by the first dispensing plate.

[0008] Preferably, the outer wall of the hemisphere is fixedly connected to multiple mounting slots; a counterweight is slidably connected inside the mounting slot; a protrusion is fixedly connected to the outer wall of the counterweight; by setting multiple counterweights, the overall mass of the hemisphere can be increased by installing multiple counterweights on the outside of the hemisphere, thereby changing the moment of inertia of the hemisphere. When all counterweights are installed, the mass of the hemisphere is the highest, and the moment of inertia is also the highest. Since the moment of inertia is inversely proportional to the natural frequency, the vibration frequency of the hemisphere is the lowest at this time, which can extend the service life of the hemisphere. Conversely, when high-frequency vibration is required, all counterweights can be removed from the mounting slots to reduce the moment of inertia of the hemisphere and increase the vibration frequency of the hemisphere.

[0009] Preferably, the outer wall of the counterweight is symmetrically rotatably connected with a clamping plate; the clamping plate has an arc-shaped structure, with a protrusion located between a pair of clamping plates, and the two sides of the protrusion are inclined; a support arm is fixedly connected to one side of the clamping plate, and a spring is fixedly connected between the support arm and the counterweight; when the operator installs the counterweight into the mounting slot through the protrusion, the two sides of the protrusion will squeeze the clamping plate and cause the clamping plate to rotate to avoid it. When the counterweight reaches the bottom of the mounting slot, the clamping plate will slide out from the end of the protrusion and reset under the elastic force of the spring. At this time, the clamping plate can limit the protrusion and the counterweight together to improve the stability of the counterweight during operation. When it is necessary to disassemble the counterweight, the support arms of the two clamping plates can be pressed at the same time to make the clamping plate rotate and move away from the protrusion. Then the counterweight can be taken out from the mounting slot through the protrusion.

[0010] Preferably, the top of the hemisphere has multiple ventilation holes. By providing ventilation holes, the sphere inside the hemisphere will frequently collide as it rotates with the axis of rotation for a long time. Some of the kinetic energy will be converted into heat energy, causing the temperature inside the hemisphere to rise and the air pressure to increase. The ventilation holes can balance the air pressure inside the hemisphere and the outside, thereby reducing the interference of air pressure changes on the movement of the sphere.

[0011] Preferably, a rod is rotatably connected through a pair of frames; a belt is fitted between the rod and the output end of the second motor; symmetrical wave-shaped grooves are provided on both sides of the rod, and a vertical rod is slidably connected within the grooves; a slide rail is fixedly installed on one side of the frame, and the frame is slidably connected to the vertical rod via the slide rail; a horizontal plate is fixedly connected to the top of the vertical rod; a push plate is provided at the end of the horizontal plate; when the second motor starts, the rod can be driven to rotate via belt drive, and when the rod rotates, the vertical rod can be driven to reciprocate horizontally along the frame via the wave-shaped grooves on its surface. The push plate and the horizontal plate move synchronously with the vertical rod, and the pressure plate can contact the piston rod of the syringe on the support plate during the reciprocating movement. The push plate can squeeze and compress the piston rod into the syringe barrel to limit and calibrate the length of the piston rod of the syringes on different support plates, reducing the production inconvenience caused by inconsistent piston rod positions of some syringes.

[0012] Preferably, a slider is fixedly connected to one side of the push plate; the slider and the horizontal plate are through-connected and slidably connected; a pair of screws are rotatably connected to one side of the pressure plate; ear plates are fixedly connected to both sides of the horizontal plate, and the ear plates are threadedly connected to the screws; before squeezing the piston rod of the syringe, the distance between the push plate and the horizontal plate can be controlled by simultaneously rotating a pair of screws, thereby adjusting the stroke of the push plate squeezing the piston rod, which can adapt to the calibration requirements of the piston rod under different production conditions.

[0013] Preferably, a pair of third flat gears are rotatably connected to the side of the horizontal plate away from the pressure plate; a transmission block is fixedly connected to one side of the third flat gears, and the transmission block is slidably connected to the end of the screw; the transmission block has a triangular structure; a rack is slidably connected to the top of the horizontal plate; the rack and the pair of third flat gears are meshed; when adjusting the pressure plate, the operator can drive the sliding convex tooth to mesh with the pair of third flat gears, and the third flat gears will rotate under the meshing action, and drive the screw to rotate together through the transmission block, so as to realize the synchronous rotation of the pair of screws by the device, simplifying the operation required to simultaneously control the screws. At this time, the rack can be fastened to the surface of the horizontal plate by bolts.

[0014] Preferably, a pressure plate is rotatably connected to the top of the horizontal plate, and the pressure plate and the horizontal plate are connected by a torsion spring; multiple protruding teeth are fixedly connected to the side of the pressure plate facing the rack; when the rack needs to be operated, the operator can turn the handle on one side of the pressure plate and rotate it. At this time, the torsion spring will be in a bent state, and the pressure plate will also move away from the rack. When the rack loses the engaging action of the protruding teeth on the surface of the pressure plate, it will be in a movable state. At this time, the rack can be operated. After adjustment, the pressure plate can be released so that the protruding teeth on the pressure plate and the protruding teeth on the rack re-engage, thereby achieving quick fixation of the rack.

[0015] Preferably, the horizontal plate has a cavity inside, and a pair of fixed rods are fixed inside the cavity; multiple iron plates are slidably connected between the pair of fixed rods; by setting the fixed rods and iron plates, when the horizontal plate moves back and forth with the upright, the iron plates will also move back and forth along the fixed rods. The assembly consisting of the horizontal plate and the upright will vibrate due to frequent movement. At this time, the friction between the iron plates and the inner wall of the cavity will convert the vibration energy into heat energy to dampen the horizontal plate and the upright.

[0016] The advantages of this invention are:

[0017] 1. The syringe processing and conveying device of the present invention, through the cooperation of the first and second distribution trays, can orderly arrange and convey the syringes conveyed by the vibratory plate to the conveying assembly, realize the rapid stacking of syringes, and facilitate subsequent processing of syringes.

[0018] 2. The syringe processing and conveying device of the present invention, through the cooperation of the ball and the protrusion, the ball can move continuously under centrifugal force and collide with the protrusion, so that the syringe on the first material distribution plate can continuously adjust its posture under vibration, thereby reducing the jamming of the syringe when it is conveyed by the first material distribution plate.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Specific implementation examples are given below.

[0033] Please see Figures 1 to 10 As shown in the embodiment of the present invention, a syringe processing and conveying device includes a chute 1, one side of which is connected to the discharge port of a vibratory feeder; the other side of the chute 1 is provided with a material handling assembly and a conveying assembly; the material handling assembly includes a mounting plate 12; a first motor 13 is fixedly connected inside the mounting plate 12; a rotating shaft 14 is fixedly connected to the output end of the first motor 13; a first distributing plate 15 is fixedly connected to the end of the rotating shaft 14; a second distributing plate 18 is provided on one side of the first distributing plate 15, and the second distributing plate 18 is inclined; both the surface of the first distributing plate 15 and the second distributing plate 18 are provided with grooves for limiting syringes; a first spur gear 161 is fixedly connected to the middle of the rotating shaft 14, and a second spur gear 162 is provided on one side of the first spur gear 161, the second spur gear 162 being rotatably connected to the mounting plate 12; the first spur gear 161 and the second spur gear 162 are meshed; the second spur gear 161... 2. A first bevel gear 171 is fixedly connected to the top; a second bevel gear 172 is fixedly connected to the middle of the second distributing plate 18, the second bevel gear 172 is rotatably connected to the mounting plate 12, and the second bevel gear 172 is meshed with the first bevel gear 171; a fixing plate 19 is provided on one side of the second distributing plate 18, and the fixing plate 19 is fixedly connected to the mounting plate 12; a baffle 110 and a support plate 1101 are fixedly connected to the surface of the fixing plate 19, the baffle 110 has an L-shaped structure, and the support plate 1101 is longer than the baffle 110; the conveying assembly includes a pair of frames 111; a pair of conveying rollers are rotatably connected between the pair of frames 111, a conveyor belt is sleeved on the conveying rollers, and multiple support plates 113 are fixedly connected to the conveyor belt; the support plate 113 is provided with a slot for limiting the syringe; a second motor 112 is fixedly connected to one side of one of the frames 111, and the output end of the second motor 112 is fixedly connected to one of the conveying rollers;

[0034] During operation, syringes accumulate inside the vibratory feeder. The vibratory feeder is activated to arrange and feed the syringes. The syringes are conveyed to the chute 1 through the vibratory feeder's outlet. The specific design of the vibratory feeder is existing technology and is therefore not described in detail here. The syringes on the chute 1 flow towards the mounting plate 12 under gravity. The first motor 13 is activated, driving the rotating shaft 14 to rotate the first distribution plate 15. Simultaneously, the rotating shaft 14 drives the first spur gear 161 to rotate synchronously. The first spur gear 161 meshes with the second spur gear 162, causing the second spur gear 162 to rotate. Gear 162 drives the first bevel gear 171 to rotate and meshes the first bevel gear 171 with the second bevel gear 172, thereby causing the second distribution plate 18 connected to the second bevel gear 172 to rotate synchronously. When the first distribution plate 15 rotates, it can limit the movement of the syringes on the chute 1 by the cooperation between the groove on its surface and the inner wall of the mounting plate 12. At this time, the protrusion on the surface of the syringe barrel is located on the surface of the first distribution plate 15 and the mounting plate 12. After the first distribution plate 15 rotates a certain distance, the syringe will move to the second distribution plate 18 and be engaged with the second distribution plate 18. 8. The syringe continues to move and disengage from the limiting position of the mounting plate 12. At the same time, the protrusion of the syringe falls onto the surface of the support plate 1101. As the second distributing plate 18 rotates, the syringe can enter the baffle 110 through the support plate 1101. The baffle 110 can limit the syringe and prevent it from falling off until the syringe moves to the end point of the support plate 1101 and the baffle 110 and slides out from the groove of the second distributing plate 18. At this time, the second motor 112 on the frame 111 is in the starting state. When the second motor 112 is started, it can drive the support plate 1 on the conveyor belt through the conveyor roller. 13 moves, and when the syringe falls out of the second distribution plate 18, it can fall onto the support plate 113 under the guidance of the baffle 110 and the end of the support plate 1101. The support plate 113 can limit the syringe barrel and protrusion through its surface groove, realizing the material sorting of the syringe during the delivery of the device. The delivery of subsequent syringes is the same as the above steps. Through the cooperation of the first distribution plate 15 and the second distribution plate 18, the syringes delivered by the vibratory plate can be sorted in an orderly manner and delivered to the delivery assembly, realizing the rapid stacking of syringes, which is convenient for subsequent processing of syringes.

[0035] Please see Figures 5 to 7 As shown, a hemisphere 2 is fixedly connected to the middle of the rotating shaft 14; a sphere 22 is provided inside the hemisphere 2; a plurality of protrusions 23 are fixedly connected inside the hemisphere 2, and the protrusions 23 are located in the upper region of the hemisphere 2.

[0036] When the first motor 13 starts, it drives the rotating shaft 14 to rotate, which in turn drives the hemisphere 2 to rotate. When the hemisphere 2 rotates, the sphere 22 inside it moves under centrifugal force. The sphere 22 slides along the inner wall of the hemisphere 2 and collides with the protrusion 23 continuously during the movement. The vibration generated by the collision can be transmitted to the first distribution plate 15 through the hemisphere 2 and the rotating shaft 14. This allows the syringe, which is limited between the first distribution plate 15 and the mounting plate 12, to continuously adjust its own posture under the action of vibration until it is adjusted to a vertical state, which is beneficial for the first distribution plate 15 to transport the syringe. Through the cooperation of the sphere 22 and the protrusion 23, the sphere 22 can move continuously under centrifugal force and collide with the protrusion 23, so that the syringe on the first distribution plate 15 can continuously adjust its posture under the action of vibration, thereby reducing the jamming of the syringe when it is transported by the first distribution plate 15.

[0037] Please see Figure 6 and Figure 7 As shown, the outer wall of the hemisphere 2 is fixedly connected with a plurality of mounting grooves 3; a counterweight 32 is slidably connected inside the mounting groove 3; and a protrusion 33 is fixedly connected to the outer wall of the counterweight 32.

[0038] By setting multiple counterweights 32, the overall mass of the hemisphere 2 can be increased by installing multiple counterweights 32 on the outside of the hemisphere 2, thereby changing the moment of inertia of the hemisphere 2. When all counterweights 32 are installed, the mass of the hemisphere 2 is the highest and the moment of inertia is also the highest. Since the moment of inertia is inversely proportional to the natural frequency, the vibration frequency of the hemisphere 2 is the lowest at this time, which can extend the service life of the hemisphere 2. Conversely, when high-frequency vibration is required, all counterweights 32 can be removed from the mounting slot 3 to reduce the moment of inertia of the hemisphere 2 and increase the vibration frequency of the hemisphere 2.

[0039] Please see Figure 7 As shown, the outer wall of the counterweight 32 is symmetrically rotatably connected with a clamping plate 4; the clamping plate 4 has an arc-shaped structure, and the protrusion 33 is located between a pair of clamping plates 4, and the two sides of the protrusion 33 are inclined; a support arm 42 is fixedly connected to one side of the clamping plate 4, and a spring is fixedly connected between the support arm 42 and the counterweight 32.

[0040] When the worker installs the counterweight 32 into the mounting groove 3 using the protrusion 33, the two sides of the protrusion 33 will press against the clamping plate 4 and cause the clamping plate 4 to rotate and avoid it. When the counterweight 32 reaches the bottom of the mounting groove 3, the clamping plate 4 will slide out from the end of the protrusion 33 and reset under the elastic force of the spring. At this time, the clamping plate 4 can limit the protrusion 33 and the counterweight 32 together to improve the stability of the counterweight 32 during operation. When it is necessary to disassemble the counterweight 32, the support arms 42 of the clamping plates on both sides can be pressed at the same time to make the clamping plate 4 rotate and move away from the protrusion 33. Then the counterweight 32 can be taken out from the mounting groove 3 through the protrusion 33.

[0041] Please see Figure 6 As shown, the top of the hemisphere 2 has multiple ventilation holes 5;

[0042] By setting ventilation holes 5, the spheres 22 inside the hemisphere 2 will collide frequently as they rotate with the shaft 14 for a long time. Some of the kinetic energy will be converted into heat energy, causing the temperature inside the hemisphere 2 to rise and the air pressure to increase. Ventilation holes 5 can balance the air pressure inside the hemisphere 2 and the outside, thereby reducing the interference of air pressure changes on the movement of the spheres 22.

[0043] Please see Figure 9 and Figure 10 As shown, a rod 6 is rotatably connected and runs through a pair of frames 111; a belt is fitted between the rod 6 and the output end of the second motor 112; wavy grooves are symmetrically opened on both sides of the rod 6, and uprights 62 are slidably connected in the grooves; a slide rail is fixedly installed on one side of the frame 111, and the frame 111 is slidably connected to the uprights 62 through the slide rail; a horizontal plate 63 is fixedly connected to the top of the uprights 62; a push plate 64 is provided at the end of the horizontal plate 63;

[0044] When the second motor 112 starts, it can drive the rod 6 to rotate via belt drive. When the rod 6 rotates, it can drive the upright 62 to move horizontally back and forth along the frame 111 via the wave-shaped groove on the surface. The push plate 64 and the horizontal plate 63 move synchronously with the upright 62. During the reciprocating movement, the push plate 64 can contact the piston rod of the syringe on the support plate 113. The push plate 64 can squeeze and compress the piston rod into the syringe barrel to limit and calibrate the length of the piston rod of the syringe on different support plates 113, reducing the production inconvenience caused by inconsistent piston rod positions of some syringes.

[0045] Please see Figure 10 As shown, a slider 72 is fixedly connected to one side of the push plate 64; the slider 72 and the horizontal plate 63 are connected through and slidably; a pair of screws 7 are rotatably connected to one side of the push plate 64; ear plates are fixedly connected to both sides of the horizontal plate 63, and the ear plates are threadedly connected to the screws 7.

[0046] Before the piston rod of the syringe is squeezed, the distance between the push plate 64 and the cross plate 63 can be controlled by simultaneously rotating a pair of screws 7. This allows for adjustment of the stroke of the push plate 64 squeezing the piston rod, thus adapting to the calibration requirements of the piston rod under different production conditions.

[0047] Please see Figure 10As shown, a pair of third spur gears 8 are rotatably connected to the side of the horizontal plate 63 away from the push plate 64; a transmission block 83 is fixedly connected to one side of the third spur gear 8, and the transmission block 83 is slidably connected to the end of the screw 7; the transmission block 83 has a triangular structure; a rack 82 is slidably connected to the top of the horizontal plate 63; the rack 82 and the pair of third spur gears 8 are in a meshing relationship.

[0048] When adjusting the push plate 64, the operator can drive the sliding tooth 92 to mesh with a pair of third flat gears 8. The third flat gears 8 will rotate under the meshing action and drive the screw 7 to rotate together through the transmission block 83, so as to realize the synchronous rotation of the pair of screws 7 by the device, simplifying the operation required to control the screws 7 at the same time. At this time, the rack 82 can be fastened to the surface of the horizontal plate 63 by bolts.

[0049] Please see Figure 10 As shown, a pressure plate 9 is rotatably connected to the top of the horizontal plate 63, and the pressure plate 9 is connected to the horizontal plate 63 by a torsion spring; multiple protruding teeth 92 are fixedly connected to the side of the pressure plate 9 facing the rack 82.

[0050] When it is necessary to operate the rack 82, the operator can turn the handle on one side of the pressure plate 9 and rotate it. At this time, the torsion spring will be in a bent state, and the pressure plate 9 will also move away from the rack 82. When the rack 82 loses the engaging action of the protruding teeth 92 on the surface of the pressure plate 9, it will be in an active state. At this time, the rack 82 can be operated. After the adjustment is completed, the pressure plate 9 can be released, so that the protruding teeth 92 on the pressure plate 9 and the protruding teeth 92 on the rack 82 can re-engage, thereby achieving quick fixation of the rack 82.

[0051] Please see Figure 10 As shown, the horizontal plate 63 has a cavity inside, and a pair of fixing rods 10 are fixed inside the cavity; a plurality of iron pieces 1001 are slidably connected between the pair of fixing rods 10.

[0052] By setting a fixed rod 10 and an iron plate 1001, when the horizontal plate 63 moves back and forth with the vertical rod 62, the iron plate 1001 will also move back and forth along the fixed rod 10. The assembly consisting of the horizontal plate 63 and the vertical rod 62 will vibrate due to frequent movement. At this time, the friction between the iron plate 1001 and the inner wall of the cavity will convert the vibration energy into heat energy to dampen the horizontal plate 63 and the vertical rod 62.

[0053] Working principle: Injectors are accumulated inside the vibratory feeder. The vibratory feeder is activated to arrange and feed the injectors. The injectors are conveyed to the chute 1 through the outlet of the vibratory feeder. The specific design of the vibratory feeder is mature existing technology, so it is not described in detail here. The injectors on the chute 1 flow towards the mounting plate 12 under the action of gravity. The first motor 13 is activated, driving the rotating shaft 14 to rotate the first distribution plate 15. Simultaneously, the rotating shaft 14 drives the first spur gear 161 to rotate synchronously. The first spur gear 161 meshes with the second spur gear 162, causing the second spur gear 162 to rotate. The second spur gear 162 then drives the first bevel gear 171 to rotate, causing the first bevel gear 171 to rotate. The first distribution plate 15 meshes with the second bevel gear 172, causing the second distribution plate 18 connected to the second bevel gear 172 to rotate synchronously. When the first distribution plate 15 rotates, it can limit the movement of the syringes on the chute 1 by the cooperation between the groove on its surface and the inner wall of the mounting plate 12. At this time, the protrusion on the surface of the syringe barrel is located on the surface of the first distribution plate 15 and the mounting plate 12. After the first distribution plate 15 rotates for a certain distance, the syringe will move to the second distribution plate 18 and be engaged in the groove inside the second distribution plate 18. Then the syringe continues to move and disengages from the limit of the mounting plate 12. At the same time, the protrusion of the syringe will fall onto the surface of the support plate 1101. As the second distribution plate 18 rotates... The syringe can enter the baffle 110 through the support plate 1101. The baffle 110 can limit the syringe and prevent it from falling off until the syringe moves to the end point of the support plate 1101 and the baffle 110 and slides out from the groove of the second distribution plate 18. At this time, the second motor 112 on the frame 111 is in the starting state. When the second motor 112 is started, it can drive the support plate 113 on the conveyor belt to move through the conveyor roller. When the syringe falls out of the second distribution plate 18, it can fall onto the support plate 113 under the guidance of the baffle 110 and the end of the support plate 1101. The support plate 113 can limit the syringe barrel and protrusion through its surface groove, realizing the device's control of the syringe barrel and protrusion. The feeding of syringes and subsequent syringe feeding are all repeated using the above steps. When the first motor 13 starts, it can drive the rotating shaft 14 to rotate. The rotating shaft 14 will drive the hemisphere 2 to rotate. When the hemisphere 2 rotates, the sphere 22 inside it can move under centrifugal force. The sphere 22 will slide along the inner wall of the hemisphere 2 and continuously collide with the protrusion 23 during the movement. The vibration generated by the collision can be transmitted to the first distribution plate 15 through the hemisphere 2 and the rotating shaft 14. This allows the syringes that are limited between the first distribution plate 15 and the mounting plate 12 to continuously adjust their own posture under the action of vibration until they are adjusted to a vertical state, which is beneficial for the first distribution plate 15 to feed the syringes.By setting multiple counterweights 32, the overall mass of the hemisphere 2 can be increased by installing multiple counterweights 32 on the outside of the hemisphere 2, thereby changing the moment of inertia of the hemisphere 2. When all counterweights 32 are installed, the mass and moment of inertia of the hemisphere 2 are at their highest. Since the moment of inertia is inversely proportional to the natural frequency, the vibration frequency of the hemisphere 2 is at its lowest at this time, which can extend the service life of the hemisphere 2. Conversely, when high-frequency vibration is required, all counterweights 32 can be removed from the mounting groove 3 to reduce the moment of inertia of the hemisphere 2 and increase the vibration frequency of the hemisphere 2. When the operator installs the counterweights 32 into the mounting groove 3 through the protrusions 33, the two sides of the protrusions 33 will squeeze the clamping plate 4 and make the clamping plate 4 enter. When the counterweight 32 reaches the bottom of the mounting groove 3, the locking plate 4 will slide out from the end of the protrusion 33 and reset under the elastic force of the spring. At this time, the locking plate 4 can limit the protrusion 33 and the counterweight 32 together to improve the stability of the counterweight 32 during operation. When the counterweight 32 needs to be disassembled, the support arms 42 of both sides of the locking plate 4 can be pressed at the same time to make the locking plate 4 rotate and move away from the protrusion 33. Then the counterweight 32 can be taken out from the mounting groove 3 through the protrusion 33. By setting the ventilation hole 5, the sphere 22 inside the hemisphere 2 will collide frequently when it rotates with the rotating shaft 14 for a long time. Some of the kinetic energy will be converted into heat energy, which will cause the temperature inside the hemisphere 2 to rise and the air pressure to increase. Ventilation hole 5 can balance the air pressure inside the hemisphere 2 and the outside, thereby reducing the interference of air pressure changes on the movement of the sphere 22. When the second motor 112 starts, it can drive the rod 6 to rotate through belt drive. When the rod 6 rotates, it can drive the upright 62 to move horizontally along the frame 111 through the wave-shaped sliding groove on the surface. The push plate 64 and the horizontal plate 63 move synchronously with the upright 62. During the reciprocating movement, the push plate 64 can contact the piston rod of the syringe on the support plate 113. The push plate 64 can squeeze and compress the piston rod into the syringe barrel to limit and calibrate the length of the piston rod of the syringe on different support plates 113, reducing the impact of inconsistent piston rod positions on some syringes. The production inconvenience is addressed by the fact that before the piston rod of the syringe is squeezed, the distance between the push plate 64 and the horizontal plate 63 can be controlled by simultaneously rotating a pair of screws 7, thereby adjusting the stroke of the push plate 64 squeezing the piston rod to adapt to the calibration requirements of the piston rod under different production conditions. When adjusting the push plate 64, the operator can drive the sliding tooth 92 to mesh with a pair of third spur gears 8. The third spur gears 8 will rotate under the meshing action and drive the screws 7 to rotate together through the transmission block 83, so as to realize the synchronous rotation of the pair of screws 7 by the device, simplifying the operation required to simultaneously operate the screws 7. At this time, the rack 82 can be fastened to the surface of the horizontal plate 63 by bolts.When the rack 82 needs to be operated, the operator can turn the handle on one side of the pressure plate 9. At this time, the torsion spring will be in a bent state, and the pressure plate 9 will move away from the rack 82. The rack 82 will be in a free state when it loses the engaging action of the protruding teeth 92 on the surface of the pressure plate 9. The rack 82 can then be operated. After adjustment, the pressure plate 9 can be released, allowing the protruding teeth 92 on the pressure plate 9 to re-engage with the protruding teeth 92 on the rack 82, achieving quick fixation of the rack 82. By setting the fixing rod 10 and the iron plate 1001, when the horizontal plate 63 moves back and forth with the vertical rod 62, the iron plate 1001 will also move back and forth along the fixing rod 10. The assembly consisting of the horizontal plate 63 and the vertical rod 62 will vibrate due to frequent movement. At this time, the friction between the iron plate 1001 and the inner wall of the cavity will convert the vibration energy into heat energy, thus damping the vibration of the horizontal plate 63 and the vertical rod 62.
