Description

Technical Field

[0001] The present invention relates to the technical field of tire manufacturing, and particularly relates to an air spring embryo punching machine. Background Art

[0002] Air springs were mainly applied to the suspension systems of railway vehicles in the early stage to improve the riding comfort and reduce the impact of vehicles on the tracks. With the continuous progress of technology, air springs have gradually been applied to fields such as automobiles, industrial machinery, aerospace, etc.

[0003] In the field of automobiles, the application of air springs began in high-end luxury models to provide a smoother driving experience and adjustable suspension height. In recent years, with the popularization of technology and the reduction of costs, more and more ordinary models have also started to adopt air springs.

[0004] An air spring mainly consists of a rubber airbag, an upper cover plate, a lower cover plate, an additional air chamber, etc. By filling compressed air into the rubber airbag, the rubber airbag expands, thereby generating an elastic force. The stiffness of the air spring can be changed by adjusting the air pressure in the rubber airbag to achieve the adjustment of the softness and hardness of the suspension system.

[0005] During the vulcanization process of the rubber airbag, i.e., the embryo, it is easy to produce appearance defects such as lack of glue and air bubbles, and it is necessary to punch holes in the rubber airbag for exhaust. In the past, manual punching was used, resulting in low efficiency. Therefore, in order to improve product quality, production efficiency, and reduce appearance defects, it is necessary to develop an air spring embryo punching device. Summary of the Invention

[0006] The purpose of the present invention is to solve the above-mentioned technical deficiencies and provide an air spring embryo punching machine.

[0007] To this end, the present invention provides an air spring embryo punching machine, including a frame. An adjusting device, a punching needle, and an expansion drum are arranged on the frame. The expansion drum is used to fix the embryo. The adjusting device is used to adjust the position of the punching needle to punch the embryo. The expansion drum rotates intermittently through a driving device. A limiting device is fixedly installed on the frame, and the limiting device is used to limit the embryo.

[0008] Preferably, the adjusting component includes a transverse moving component and a longitudinal moving component. The longitudinal moving component is installed on the frame, and the transverse moving component is installed on the longitudinal moving component. The longitudinal moving component is used to drive the transverse moving component to move vertically, and the transverse moving component is used to drive the punching needle to adjust horizontally.

[0009] Preferably, the driving device includes a push cylinder, a first chain, a one-way flywheel, a spring and a driving shaft. The push cylinder is fixedly installed on the frame. One end of the first chain is connected to the output end of the push cylinder, and the other end is connected to the spring. The other end of the spring is installed on the frame on one side of the push cylinder. The push cylinder drives the one-way flywheel to rotate through the first chain. The one-way flywheel is installed on the driving shaft, and the driving shaft is connected to the driven shaft through a transmission component. The driven shaft is used to drive the expansion drum to rotate.

[0010] Preferably, the limiting device includes a positioning disk and roller shafts. The positioning disk is fixedly installed on the frame and is coaxially arranged with the expansion drum. A plurality of roller shafts are installed in the positioning disk, and the plurality of roller shafts are arranged in a circular array.

[0011] Preferably, the expansion drum is detachably connected to the driven shaft and is internally connected to the driven shaft. Compressed air is input through a rotary joint at one end of the driven shaft.

[0012] Preferably, the expansion drum is composed of a plurality of expansion drum bodies. The plurality of expansion drum bodies are connected to each other through a ventilation device, and the distance between adjacent two expansion drum bodies is adjusted through an adjustment component.

[0013] Preferably, the expansion drum body includes a support cylinder, a sealing plate, a clamping disc and a capsule. The support cylinder is fixedly installed on the outer side of the sealing plate, and the clamping disc is fixedly installed on the inner side of the sealing plate. An inward concave clamping space is formed between the clamping disc, the support cylinder and the sealing plate, and the clamping space is used to clamp the capsule.

[0014] Preferably, a plurality of through holes are circumferentially formed in the clamping disc, and the through holes are connected to the inner cavity of the capsule. The inner cavity is inflated through the ventilation device.

[0015] Preferably, the manufacturing method of the capsule includes the following steps:

[0016] S1. Fix the forming cylinder to the left mold, and sequentially attach a first film, multiple layers of cord fabric and a second film to the forming cylinder and the left mold. The first film, the cord fabric and the second film together form the capsule body;

[0017] S2. Use a connecting piece to compact the capsule body at the edge of the left mold;

[0018] S3. Turn the other end of the capsule body back to the flange of the connecting piece;

[0019] S4. Use the right mold to be fixedly connected to the connecting piece and press the capsule body at the flange;

[0020] S5. Continue to turn the already turned-back capsule body back to the right mold until it is symmetric about the connecting piece left and right;

[0021] S6. Wrap the symmetric capsule body with cloth strips and wait for vulcanization.

[0022] The beneficial effects of the present invention are as follows: The present invention provides an air spring embryo punching machine, which has the following beneficial effects.

[0023] (1) Under the action of the horizontal moving component, the punching needle can adjust the horizontal position of the punching needle at any time according to the size of air spring embryos of different specifications. After adjustment, the punching needle can, under the action of the vertical moving component, punch holes downward at the positions where air bubbles are likely to occur, such as the bell mouth, the middle, and the tail slope of the embryo. Moreover, the embryo can also rotate at a fixed distance intermittently under the action of the driving device, reducing appearance defects, improving production efficiency, reducing the labor intensity and error of manual operation, and ensuring the stability of product quality.

[0024] (2) The positioning disk is coaxially arranged with the expansion drum. When the embryo is sleeved on the expansion drum, the positioning disk can play a good limiting role, meeting the positioning requirements of embryos of different specifications. When punching holes in embryos of the same specification, due to the limitation of the positioning disk, there is no need to adjust the position of the punching needle every time, improving work efficiency. At the same time, the positioning disk is equipped with roller shafts arranged in an annular array, which can not only reduce the friction with the embryo and reduce the resistance of the embryo rotation, but also when the embryo rotates intermittently, the position of each punching needle is located at the vacancy between two roller shafts each time, playing a protective role for the punching needle and reducing the damage of the punching needle.

[0025] (3) Use the push cylinder to drive the driving shaft to rotate intermittently, and the driving shaft then drives the driven shaft to rotate intermittently through the transmission component, so that the driven shaft and the driving shaft are independent of each other, which is conducive to inputting compressed air into the driven shaft, and then driving the expansion drum to expand to automatically center and fix the position of the embryo.

[0026] (4) Adjust the distance between adjacent expansion drum bodies through the adjustment component, which can meet the punching requirements of embryos of different lengths. Description of the Drawings

Detailed implementation mode

[0042] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments to help understand the content of the present invention. The methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercially available products unless otherwise specified.

[0043] Embodiment:

[0044] As Figures 1 to 14 shown, the present invention provides an air spring blastocyst puncturing machine, including a frame 1, which is welded by 60*60 square tubes and σ = 4mm iron plates. An adjusting device, a needle 2 and an expansion drum 3 are arranged on the frame 1. The expansion drum 3 is used to fix the blastocyst 4, and the adjusting device is used to adjust the position of the needle 2 to puncture the blastocyst 4. The expansion drum 3 rotates intermittently through a driving device 5. A limiting device 6 is fixedly installed on the frame 1, and the limiting device 6 is used to limit the blastocyst 4.

[0045] Furthermore, as Figures 1 to 3 shown, the adjusting component includes a transverse movement component 7 and a longitudinal movement component 8. The longitudinal movement component 8 is installed on the frame 1, and the transverse movement component 7 is installed on the longitudinal movement component 8. The longitudinal movement component 8 is used to drive the transverse movement component 7 to move vertically, and the transverse movement component 7 is used to drive the needle 2 to adjust horizontally and puncture vertically.

[0046] The longitudinal movement component 8 includes a first cylinder 81, a guide rail 82, and a slider 83. The cylinder block of the first cylinder 81 is vertically and fixedly installed on the frame 1. The output end of the first cylinder 81 is connected to the transverse movement component 7. A vertical guide rail 82 is fixedly installed on the frame 1, and a slider 83 is fixedly installed on the transverse movement component 7. The slider 83 is slidably connected to the guide rail 82.

[0047] In this embodiment, the number of the guide rails 82 is two. The two guide rails 82 are both fixedly installed on the frame 1 and arranged in parallel. The two sliders 83 slide along the corresponding guide rails 82, enhancing the stability during the vertical movement.

[0048] The transverse movement component 7 includes a second cylinder 71, a lead screw 72, a support frame 73, and a mounting frame 74. A fixed plate 22 is welded inside the support frame 73. The middle position of the fixed plate 22 is connected to the output end of the first cylinder 81. Sliders 83 are fixedly installed at both ends of the fixed plate 22. A horizontally arranged lead screw 72 is rotatably installed on the support frame 73. A mounting frame 74 is threadedly connected to the lead screw 72. A second cylinder 71 is detachably installed on the mounting frame 74. The output end of the second cylinder 71 is fixedly connected to the puncturing needle 2. The puncturing needle 2 is arranged towards the position where the blastocyst 4 needs to be punctured. The orientation of the puncturing needle 2 can adjust the installation position and inclination angle of the second cylinder 71 at any time according to the puncturing position.

[0049] Further, the first cylinder 81 is fixedly installed on the top of the frame 1 through a connecting plate 30. The bottom of the limit rod 32 is fixedly installed on the fixed plate 22. Its top passes through the connecting plate 30 and is limited and adjusted by a nut 33. The nut 33 is threadedly connected to the upper part of the limit rod 32. During the puncturing process, the vertical movement distance of the first cylinder 81 is limited by adjusting the position of the nut 33.

[0050] In this embodiment, the number of the lead screws 72 is two. The two lead screws 72 are arranged parallel to each other up and down. One end of the lead screw 72 is rotatably connected to the inner side of the support frame 73, that is, the side close to the fixed plate 22, through a bearing 23. The other end of the lead screw 72 penetrates through the outer side of the support frame 73 and is fixedly installed with a handwheel 24. Optical axes 25 arranged parallel to the lead screw 72 are fixedly installed on the support frame 73 on both the upper and lower sides of the lead screw 72.

[0051] In this embodiment, the mounting bracket 74 includes a first mounting bracket 741, a second mounting bracket 742, and a third mounting bracket 743, which are arranged in sequence from left to right. The puncturing needle 2 on the first mounting bracket 741 is used to puncture the flared opening position of the blastocyst 4, the puncturing needle 2 on the second mounting bracket 742 is used to puncture the middle position of the blastocyst 4, and the third mounting bracket 743 is used to puncture the tail inclined plane of the blastocyst 4. Among them, the first mounting bracket 741 and the third mounting bracket 743 are respectively threadedly connected to the corresponding lead screws 72, and both the upper and lower ends are sleeved on the optical axis 25 and slide thereon. The second mounting bracket 742 is sleeved on the lead screw 72 and the optical axis 25 and slides along them. When it is necessary to fix the position of the second mounting bracket 742, a first setscrew is used to pass through the second mounting bracket 742 and tighten it against the optical axis 25 for fixation.

[0052] Further, as Figure 4 and Figure 5 shown, the driving device 5 includes a push cylinder 51, a first chain 52, a one-way flywheel 53, a spring 54, and a driving shaft 55. The push cylinder 51 is a pneumatic cylinder, and the first chain 52 is a bicycle chain. The push cylinder 51 is fixedly installed on the frame 1 through a mounting plate 26. One end of the first chain 52 is connected to the output end of the push cylinder 51, and the other end is connected to the spring 54. The other end of the spring 54 is installed on the mounting plate 26 on one side of the push cylinder 51. The push cylinder 51 drives the one-way flywheel 53 to rotate through the first chain 52. The one-way flywheel 53 is installed on the driving shaft 55. The driving shaft 55 is rotatably installed on the frame 1 through a first pillow block bearing 27. The first pillow block bearing 27 is a UCP206 pillow block bearing. The driving shaft 55 is connected to the driven shaft 10 through a transmission component 9. The driven shaft 10 is used to drive the expansion drum 3 to rotate. The driven shaft 10 is installed on the frame 1 through a second pillow block bearing 29. The second pillow block bearing 29 is a UCP208 pillow block bearing.

[0053] The transmission component 9 includes a driving sprocket 91, a driven sprocket 92, and a driving chain 93. The driving sprocket 91 is fixedly installed on the driving shaft 55, the driven sprocket 92 is fixedly installed on the driven shaft 10, and the driving chain 93 is sleeved on the driving sprocket 91 and the driven sprocket 92, so that the driving sprocket 91 drives the driven sprocket 92 to rotate.

[0054] The diameter of the driven sprocket 92 is larger than that of the driving sprocket 91, which has a speed reduction effect and matches the transmission ratio.

[0055] When it is necessary to drive the blastocyst 4 on the expansion drum 3 to rotate, the push cylinder 51 is started. The push cylinder 51 pulls down or pushes up, and drives the first chain 52 to move under the action of the spring 54, thereby driving the one-way flywheel 53 to rotate. The rotation of the one-way flywheel 53 drives the rotation of the drive shaft 55 and the driving sprocket 91. The driving sprocket 91 drives the driven sprocket 92 to rotate through the drive chain 93, thereby driving the rotation of the driven shaft 10. The driven shaft 10 drives the expansion drum 3 to rotate intermittently. In this embodiment, the expansion drum 3 rotates 20 mm each time, and this process repeats in a cycle.

[0056] Furthermore, the limiting device 6 includes a positioning disk 61 and roller shafts 62. The positioning disk 61 is fixedly installed on the frame 1 and is coaxially arranged with the expansion drum 3. A plurality of roller shafts 62 are installed in the positioning disk 61, and the plurality of roller shafts 62 are arranged in a circular array.

[0057] When the blastocyst 4 is sleeved on the expansion drum 3, the positioning disk 61 can achieve a good limiting effect and meet the positioning requirements of blastocysts 4 of different specifications. When puncturing blastocysts 4 of the same specification, there is no need to adjust the position of the puncturing needle 2 every time, which improves the working efficiency. At the same time, the roller shafts 62 arranged in a circular array are installed on the positioning disk 61, which can not only reduce the friction with the blastocyst 4 and reduce the resistance of the blastocyst 4 to rotate, but also when the blastocyst 4 rotates intermittently, the position of each puncture is at the gap between two roller shafts 62, which plays a protective role for the puncturing needle 2 and reduces the damage of the puncturing needle 2.

[0058] Furthermore, the expansion drum 3 is detachably connected to the driven shaft 10, which is convenient for replacing the expansion drum 3. And the expansion drum 3 is internally connected to the driven shaft 10. Compressed air is input through one end of the driven shaft 10 by a rotary joint 11. A quick exhaust valve 28 is connected to the rotary joint 11. The quick exhaust valve 28 is connected to equipment such as an air compressor through a pipeline, and then compressed air is input into the expansion drum 3 through the driven shaft 10.

[0059] The rotary joint 11 can rotate along with the rotation of the driven shaft 10, thus avoiding pipeline entanglement and ensuring the smooth progress of the air inflation and puncturing operations.

[0060] Furthermore, an air storage tank 40 is provided on the frame 1, and the air storage tank 40 is used to prevent pipeline pressure fluctuations.

[0061] Furthermore, as Figures 6 to 8 shown, the expansion drum 3 is composed of a plurality of expansion drum bodies 31. The plurality of expansion drum bodies 31 are connected to each other through a ventilation device, and the distance between adjacent two expansion drum bodies 31 is adjusted by an adjustment component 12. The number of expansion drum bodies 31 in this embodiment is two.

[0062] The adjustment component 12 includes a first connecting shaft 121 and a second connecting shaft 122. The first connecting shaft 121 is coaxially and fixedly installed on the front expansion drum body 31, and the second connecting shaft 122 is coaxially and fixedly installed on the rear expansion drum body 31. The second connecting shaft 122 is inserted into the first connecting shaft 121 and slides therein and is fixed by a fixing component.

[0063] The fixing component includes a second setscrew and a threaded hole 35. The threaded hole 35 is formed on the first connecting shaft 121, and the second setscrew is threadedly connected to the threaded hole 35 to tightly fix the position of the second connecting shaft 122.

[0064] Furthermore, the expansion drum body 31 includes a support cylinder 311, a sealing plate 312, a chuck 313 and a capsule 314. The support cylinder 311 is fixedly installed on the outer side of the sealing plate 312 by bolts, and the chuck 313 is fixedly installed on the inner side of the sealing plate 312 by bolts. An inward concave annular clamping space 13 is formed between the chuck 313, the support cylinder 311 and the sealing plate 312, and the clamping space 13 is used for clamping the capsule 314.

[0065] The sealing plate 312 includes a left sealing plate 3121 and a right sealing plate 3122. The left support cylinder 311, the left sealing plate 3121, the chuck 313, the right sealing plate 3122 and the right support cylinder 311 are fixedly connected in sequence.

[0066] Furthermore, a plurality of uniformly distributed through holes 14 are circumferentially formed on the chuck 313. The through holes 14 are communicated with the inner cavity 15 of the capsule 314, and the inner cavity 15 is inflated by an air venting device.

[0067] The air venting device includes a first air venting component and a second air venting component. The first air venting component is communicated with the second air venting component. The first air venting component is used for venting the expansion drum body 31 connected to the installation shaft 34. The installation shaft 34 is detachably connected to the driven shaft 10 by bolts. The second air venting component is used for venting the remaining plurality of expansion drum bodies 31.

[0068] The first air venting component includes a central hole 36 formed on the left sealing plate 3121. One side of the central hole 36 is communicated with the installation shaft 34, the installation shaft 34 is communicated with the driven shaft 10, and the other side of the central hole 36 is communicated with the chuck 313 and is communicated with the inner cavity 15 of the capsule 314 through the through hole 14.

[0069] The second air venting component includes a quick socket 37 and a quick insertion tube 38. Quick sockets 37 are provided on both the right sealing plate 3122 of the front expansion drum body 31 and the left sealing plate 3121 of the rear expansion drum body 31. The quick sockets 37 are communicated with the chuck 313, and the quick sockets 37 are communicated with each other through the quick insertion tube 38.

[0070] When the expansion drum body 31 needs to be inflated, the quick exhaust valve 28 is connected to equipment such as an air compressor through a pipeline, and the air in the quick exhaust valve 28 is input into the mounting shaft 34 through the driven shaft 10. The air in the mounting shaft 34 enters the chuck 313 of the left expansion drum body 31 through the center hole 36, and enters the inner cavity 15 of the capsule 314 through the through hole 14, thereby inflating the capsule 314 on the left expansion drum body 31.

[0071] The air entering the chuck 313 will continue to enter the quick-insert tube 38 through the quick-insert port 37 on the right sealing plate 3122 of the left expansion drum body 31. Under the action of the quick-insert tube 38, the compressed air will enter the chuck 313 of the right expansion drum body 31 through the quick-insert port 37 on the left sealing plate 3121 of the right expansion drum body 31, and continue to enter the inner cavity 15 of the capsule 314 along the through hole 14 to inflate the right expansion drum body 31. At this point, the inflation work of the two expansion drum bodies 31 is completed. The inflation operation in this embodiment can adjust the inflation pressure of the expansion drum 3 at any time to achieve synchronous inflation of multiple expansion drum bodies 31, which greatly improves the inflation efficiency.

[0072] Further, such as Figure 9 As shown, the method for making capsule 314 comprises the following steps:

[0073] S1, such as Figure 10 As shown, the forming cylinder 16 and the left mold 17 are fixedly connected by bolts, and the first film, the second layer of curtain fabric with a thickness of 1 mm and the second film with a thickness of 0.7 mm are sequentially attached to the forming cylinder 16 and the left mold 17. When attaching, the bubbles on the first film, the curtain fabric and the second film are punctured and compacted by a pressing roller. The first film, the curtain fabric and the second film together constitute a capsule body 18;

[0074] S2, such as Figure 11 As shown, the connecting member 19 is fixed to the left mold 17 by bolts, and the capsule body 18 at the edge of the left mold 17 is compacted;

[0075] S3, such as Figure 12 As shown, the other end of the capsule body 18 is manually reversed to the flange 20 of the connecting member 19;

[0076] S4, such as Figure 13 As shown, the right mold 21 is fixedly connected to the connecting member 19 by bolts and the capsule body 18 at the flange 20 is pressed;

[0077] S5, such as Figure 14 As shown, the reversed capsule body 18 is further reversed toward the right mold 21 until it is symmetrical along the connecting piece 19;

[0078] S6. Wrap the symmetric capsule body 18 with a cloth strip, wait for vulcanization, and then remove the forming cylinder 16.

[0079] S7. Send the capsule body 18, the left mold 17, the connecting piece 19, and the right mold 21 into a vulcanizing tank for vulcanization. After vulcanization is completed, introduce cold air into the left mold 17 or the right mold 21. Since the interiors of the left mold 17, the right mold 21, and the connecting piece 19 are connected, the cold air in the left mold 17 or the right mold 21 is input to the capsule body 18 through the ventilation pipe 39 on the connecting piece 19, so as to separate the lower surface of the capsule body 18 from the left mold 17, the right mold 21, and the connecting piece 19. After deflation, remove the bolts between the left mold 17, the connecting piece 19, and the right mold 21 and take out the capsule body 18.

[0080] The manufacturing process of the above-mentioned capsule 314 can quickly complete the preparation of the capsule body 18. The preparation process is simple and fast, with strong stability, and can meet the manufacturing requirements of capsule bodies 18 of different specifications, laying a foundation for the normal use of the capsule 314 on the expansion drum 3 in the future.

[0081] The working principle is as follows:

[0082] First, according to the preparation method of the capsule 314, use the forming cylinder 16, the left mold 17, the connecting piece 19, and the right mold 21 to fix and form the capsule 314 and carry out vulcanization. Clamp and fix the vulcanized capsule 314 through the clamping space 13 formed by the support cylinder 311, the left sealing plate 3121, the chuck 313, and the right sealing plate 3122.

[0083] Then, fixedly install the expansion drum body 31 with the mounting shaft 34 on the driven shaft 10 through bolts. Then, according to the length of the blastocyst 4, insert the second connecting shaft 122 on another expansion drum body 31 into the first connecting shaft 121 of the already installed expansion drum body 31, adjust the distance between the two expansion drum bodies 31. After the adjustment is completed, use the second setscrew to fix the position of the second connecting shaft 122.

[0084] Secondly, the blastocyst 4 is sleeved on the expansion drum 3, such that the bell mouth of the blastocyst 4 abuts against the roller 62 of the positioning disk 61. The quick exhaust valve 28 is used to input compressed air into the driven shaft 10. The compressed air in the driven shaft 10 enters the chuck 313 of the first expansion drum body 31 through the mounting shaft 34 and the central hole 36, and enters the inner cavity 15 of the capsule 314 through the through hole 14 on the chuck 313, causing the capsule 314 on the first expansion drum body 31 to expand. When the compressed air enters the chuck 313 of the first expansion drum body 31, the entering air will also simultaneously pass through the quick socket 37 on its right sealing plate 3122, through the quick insertion tube 38, and into the chuck 313 of the second expansion drum body 31 through the quick socket 37 on the left sealing plate 3121 of the second expansion drum body 31, and then enters the inner cavity 15 of the second expansion drum body 31 under the action of the through hole 14, causing the capsule 314 on the second expansion drum body 31 to expand. Through the above operations, the synchronous expansion of the two expansion drum bodies 31 is achieved, thus completing the automatic centering and fixing of the blastocyst 4.

[0085] Then, according to the position of the blastocyst 4, the handwheel 24 is shaken, such that the handwheel 24 drives the lead screw 72 to rotate, thereby driving the mounting bracket 74 on the lead screw 72 to horizontally move along the lead screw 72, moving the puncturing needle 2 to a suitable position. The puncturing needle 2 on the second mounting bracket 742 is also fixed at a suitable position through the first setscrew, and then the lifting cylinder one 81 is started. Under the limitation of the limiting rod 32, the cylinder one 81 drives the puncturing needle 2 to move downward to a suitable height.

[0086] Secondly, the solenoid valve is started, and the solenoid valve is used to control the piston rod of the push cylinder 51 to move downward, such that the first chain 52 drives the one-way flywheel 53 to rotate and drives the drive shaft 55 to rotate a certain angle. The rotation of the drive shaft 55 simultaneously drives the driven sprocket 92 to rotate through the driving sprocket 91 and the drive chain 93, and then causes the driven shaft 10 to rotate a certain angle. The rotation of the driven shaft 10 also drives the expansion drum 3 to rotate a corresponding certain angle. The set rotation angle of the expansion drum 3 is designed through calculation based on controlling the downward stroke of the push cylinder 51 and according to the number of teeth of the one-way flywheel 53, the number of teeth of the driving sprocket 91, and the number of teeth of the driven sprocket 92.

[0087] Finally, the start button on the operation panel 41 is pressed to start one or more guide rod cylinders two 71. The guide rod cylinders two 71 descend and perform a puncturing operation on both sides and the middle position of the blastocyst 4. The time relay is used to control the cycle time of the puncturing of the puncturing needle 2. After the puncturing is completed, the guide rod cylinders two 71 drive the puncturing needle 2 to rise. The driven shaft 10 continues to rotate a certain angle under the action of the push cylinder 51, and then repeats the puncturing action of the next beat, enabling it to puncture the air spring blastocyst 4 at certain intervals. After the puncturing of the blastocyst 4 is completed, the expansion drum 3 is deflated through the button on the operation panel 41, the blastocyst 4 is removed, and the next round of cycle begins.
