DETAILED DESCRIPTION

[0030] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0031] See also Figure 1 and Figure 3 , an automatic packaging machine for blister particles, comprising a base plate 1, a rotating shaft 2, a rotating disk 3, a fixing component 4, a supporting ring 5, a transposition component 6 and a blanking component 7. The base plate 1 is placed on the ground, the upper end surface of the base plate 1 is fixedly connected to the rotating shaft 2, the upper end surface of the rotating shaft 2 is rotatably connected to the rotating disk 3, four fixing components 4 are evenly fixedly connected on the annular outer surface of the rotating disk 3 along its circumferential direction, the upper end surface of the base plate 1 is fixedly connected to the supporting ring 5 through a bracket, the outer surface of the rotating shaft 2 is installed with a transposition component 6, and the upper end surface of the base plate 1 is located on the right side of the rotating shaft 2 and is installed with a blanking component 7.

[0032] See also Figure 1 , Figure 3 and Figure 4The fixing assembly 4 includes a connecting shaft 41, a fixing platform 42, a clamping mechanism 43, a limiting rod 44, a sliding block 45 and a limiting mechanism 46. The connecting shaft 41 is rotatably connected to the outer surface of the circular ring of the rotating disk 3, and the end of the connecting shaft 41 away from the rotating disk 3 is fixedly connected to the fixing platform 42, and the clamping mechanism 43 is installed on the upper and lower end surfaces of the fixing platform 42. An annular groove is provided on the inner surface of the supporting ring 5, and the end of the fixing platform 42 away from the connecting shaft 41 is fixedly connected to the limiting rod 44, and the end of the limiting rod 44 away from the fixing platform 42 is rotatably connected to the sliding block 45. The sliding block 45 is slidably connected in the annular groove, and a limiting mechanism 46 is installed between the limiting rod 44 and the sliding block 45.

[0033] See also Figure 1 , Figure 2 and Figure 5 The clamping mechanism 43 includes a bracket plate 431, a threaded rod 432, a rotating head 433, a clamping plate 434, a linkage rod 435 and a fixed plate 436. The bracket plate 431 is fixedly connected to one end of the upper end surface of the fixed platform 42 close to the limiting axis, and the threaded rod 432 is threadedly connected to the bracket plate 431. The rotating head 433 is fixedly connected to one end of the threaded rod 432 away from the connecting shaft 41. The clamping plate 434 is rotatably connected to one end of the threaded rod 432 close to the connecting shaft 41. Linkage rods 435 are hinged on both sides of the clamping plate 434 in the horizontal direction. The end of the linkage rod 435 away from the clamping plate 434 is hinged to a fixed plate 436. The two fixed plates 436 can only slide in a direction in which they are close to or away from each other.

[0034] During the specific work, the packaging mold is manually placed on the fixed table 42, and then the rotating head 433 is rotated. The rotating head 433 drives the threaded rod 432 to rotate, and then the clamping plate 434 moves away from the rotating head 433. During the movement, the clamping plate 434 causes the two linkage rods 435 to rotate, and further causes the two fixed plates 436 to move in a direction close to each other. When the clamping plate 434 contacts the packaging mold, the two fixed plates 436 also contact the packaging mold at the same time, thereby realizing the limited fixation of the packaging mold in multiple directions. When the four packaging molds of the same kind are all fixed, the fixing assembly 4 is manually turned over, and then the four packaging molds of another kind are fixed in another clamping mechanism 43 of the fixing assembly 4 using the above steps.

[0035] See also Figure 3 and Figure 6The unloading assembly 7 includes an unloading rack 71, a slide plate 72, a slide block 73, an electric push rod 74, a slide column 75, a sliding frame 76, a rubber suction cup 77, an unloading spring 78 and an air jet mechanism 79. The unloading rack 71 is fixedly connected to the right side of the upper end surface of the bottom plate 1, and the unloading rack 71 is fixedly connected to the slide plate 72. The lower end surface of the slide plate 72 is slidably connected to the slide block 73. The lower end surface of the slide block 73 is fixedly connected to the electric push rod 74. The electric push rod The output end of 74 is fixedly connected with a sliding column 75, and the sliding column 75 is a stepped square column structure. A sliding frame 76 is sleeved and slidably connected to the sliding column 75. A plurality of suction holes are evenly opened on the lower end surface of the sliding frame 76. A rubber suction cup 77 is fixedly connected to the lower end surface of the sliding frame 76 and the corresponding positions of the suction holes. A feeding spring 78 is fixedly connected between the upper end surface of the sliding frame 76 and the lower end surface of the slide rail block 73. The lower end surface of the slide rail block 73 is fixedly connected with an injection mechanism 79.

[0036] During specific operation, the external clearance rotating device is used to drive the rotating shaft 2 to rotate, and the rotating shaft 2 drives the rotating disk 3 to rotate, further driving the fixed component 4 to rotate. The fixed component 4 performs different tasks when it is in different positions. The front and left positions correspond to the loading step and the paper card adding step respectively. When the fixed component 4 rotates to the rear position, the heat sealing device performs heat sealing and packaging treatment on the packaging mold. Then, when it rotates to the right position, the external mobile device first drives the slide rail block 73 to slide above the fixed component 4, and then the electric push rod 74 is started. The output end of the electric push rod 74 drives the slide column 75 to move downward. Because the initial state of the unloading spring 78 is a compressed state, the slide column 75 is larger than the upper end surface of the square column and the sliding The top surface of the frame 76 is in close contact with the product. When it moves down to the point where the rubber suction cup 77 contacts the product, the feeding spring 78 just returns to its original length. Then the output end of the electric push rod 74 continues to extend, causing the slide column 75 to slide in the sliding frame 76. When the lower end surface of the slide column 75 contacts the bottom surface of the sliding frame 76, the electric push rod 74 retracts the output end, and the output end drives the slide column 75 to move upward. At this time, the sliding frame 76 is stationary due to the feeding spring 78, and then the slide column 75 slides inside the sliding frame 76 and generates suction on the product below. When the suction is sufficient, the slide column 75 will drive the sliding frame 76 and the product to move upward together. After rising to the specified position, the external mobile device drives the slide rail block 73 to slide to the collection position for product collection.

[0037] See also Figure 6The jet mechanism 79 includes a telescopic airbag 791, an air supply pipe 792, an air nozzle 793, an air inlet pipe 794, a first one-way valve 795 and a second one-way valve 796. The lower end surface of the slide rail block 73 is fixedly connected with the telescopic airbag 791, the telescopic airbag 791 is fixedly connected with the air supply pipe 792, the end of the air supply pipe 792 away from the telescopic airbag 791 is fixedly connected with the air nozzle 793, the air nozzle 793 is fixedly connected to the right end surface of the sliding frame 76, the air supply pipe 792 is connected with the air inlet pipe 794, the air inlet pipe 794 is installed with a first one-way valve 795, and the second one-way valve 796 is installed in the air supply pipe 792 near the air nozzle 793.

[0038] During specific operation, when the sliding column 75 moves downward, the telescopic airbag 791 inhales air by its own elastic force. At this time, the second one-way valve 796 is closed and the first one-way valve 795 is opened. The air enters the air inlet pipe 794 through the first one-way valve 795 and then enters the telescopic airbag 791 through the air supply pipe 792. When the sliding column 75 rises, the upper end surface of the sliding column 75 will squeeze the telescopic airbag 791. At this time, the first one-way valve 795 is closed and the second one-way valve 796 is opened. The air in the telescopic airbag 791 will pass through the air supply pipe 792 to the air nozzle 793 and be ejected from the air nozzle 793. The ejected gas blows toward the product, thereby realizing heat dissipation of the product after heat sealing and packaging.

[0039] See also Figure 3 The conversion assembly includes a fixed bevel gear 61, a hydraulic push rod 62 and a driven bevel gear 63. The fixed bevel gear 61 is slidably connected to the outer surface of the rotating shaft 2, the hydraulic push rod 62 is fixedly connected to the lower end surface of the fixed bevel gear 61, and the driven bevel gear 63 is fixedly connected to the connecting shaft 41.

[0040] See also Figure 4 The limiting mechanism 46 includes a hemispherical groove 461, a stop rod 462 and a telescopic spring 463. The hemispherical groove 461 is symmetrically provided at the connection between the sliding block 45 and the limiting rod 44. A limiting hole is provided on the outer surface of the limiting rod 44 at a position corresponding to the hemispherical groove 461. The stop rod 462 is slidably connected in the limiting hole. The telescopic spring 463 is fixedly connected between the stop rod 462 and the inner wall of the limiting hole. The end of the stop rod 462 away from the telescopic spring 463 is set as a hemispherical clamp.

[0041] During specific work, when the packaging mold needs to be replaced, first stop the steps on each workstation and start the hydraulic push rod 62. The output end of the hydraulic push rod 62 drives the fixed bevel gear 61 to move upward. After engaging with the driven bevel gear 63, the driven bevel gear 63 rotates with the rotation of the external intermittent rotating device, and further flips the fixed component 4. During the flipping process, the stop rod 462 will first exit the hemispherical groove 461 and fit tightly against the inner surface of the sliding block 45. When the flipping is completed, the stop block 462 is just located at the other hemispherical groove 461. At this time, the telescopic spring 463 extends to drive the stop block 462 into the hemispherical groove to complete the rotation limit.

[0042] When the above-mentioned blister particle automatic packaging machine is used for packaging, the specific packaging method includes the following steps: S1: manually place the packaging mold on the fixed table 42, and then rotate the rotating head 433. The rotating head 433 drives the threaded rod 432 to rotate, thereby causing the clamping plate 434 to move away from the rotating head 433. During the movement, the clamping plate 434 causes the two linkage rods 435 to rotate, and further causes the two fixed plates 436 to move in a direction close to each other. When the clamping plate 434 contacts the packaging mold, the two fixed plates 436 also contact the packaging mold at the same time, thereby realizing the limited fixation of the packaging mold in multiple directions. When the four packaging molds of the same type are all fixed, the fixing component 4 is manually turned over, and then the four packaging molds of another type are fixed in another clamping mechanism 43 of the fixing component 4 using the above steps.

[0043] S2: The rotating device drives the rotating shaft 2 to rotate by utilizing the external clearance, and the rotating shaft 2 drives the rotating disk 3 to rotate, further driving the fixed component 4 to rotate. The fixed component 4 performs different tasks when it is in different positions. The front and left positions correspond to the loading step and the paper card adding step respectively. When the fixed component 4 rotates to the rear position, the heat sealing device performs heat sealing and packaging processing on the packaging mold. Then, when it rotates to the right position, the external mobile device first drives the slide block 73 to slide above the fixed component 4, and then the electric push rod 74 is started. The output end of the electric push rod 74 drives the slide column 75 to move downward. Because the unloading spring 78 is initially in a compressed state, the slide column 75 is larger than the upper end surface of the square column and is close to the sliding frame 7. 6, and when the rubber suction cup 77 moves down to contact the product, the feeding spring 78 just returns to its original length, and then the output end of the electric push rod 74 continues to extend, causing the slide column 75 to slide in the slide frame 76. When the lower end surface of the slide column 75 contacts the inner bottom surface of the slide frame 76, the electric push rod 74 retracts the output end, and the output end drives the slide column 75 to move upward. At this time, the slide frame 76 is stationary due to the feeding spring 78, and then the slide column 75 slides inside the slide frame 76 and generates suction for the product below. When the suction is sufficient, the slide column 75 will drive the slide frame 76 and the product to move upward together. After rising to the specified position, the external mobile device drives the slide rail block 73 to slide to the collection position for product collection.

[0044] S3: When the slide column 75 moves downward, the telescopic airbag 791 inhales air by its own elastic force. At this time, the second one-way valve 796 is closed and the first one-way valve 795 is opened. The air enters the air inlet pipe 794 through the first one-way valve 795 and then enters the telescopic airbag 791 through the air supply pipe 792. When the slide column 75 rises, the upper end surface of the slide column 75 squeezes the telescopic airbag 791. At this time, the first one-way valve 795 is closed and the second one-way valve 796 is opened. The air in the telescopic airbag 791 passes through the air supply pipe 792 to the air nozzle 793 and is ejected from the air nozzle 793. The ejected gas blows toward the product, thereby realizing heat dissipation of the product after heat sealing and packaging.

[0045] S4: When the packaging mold needs to be replaced during work, first stop the steps on each workstation and start the hydraulic push rod 62. The output end of the hydraulic push rod 62 drives the fixed bevel gear 61 to move upward. After engaging with the driven bevel gear 63, the driven bevel gear 63 rotates with the rotation of the external intermittent rotating device, and further flips the fixed component 4. During the flipping process, the stop rod 462 will first exit the hemispherical groove 461 and fit tightly against the inner surface of the sliding block 45. When the flipping is completed, the stop block 462 is just located at the other hemispherical groove 461. At this time, the telescopic spring 463 extends to drive the stop block 462 into the hemispherical groove to complete the rotation limit.
