[0046] As Figures 1 to 17As shown, a synchronous and efficient traditional Chinese medicine particle quantitative dispensing equipment includes a rotating disc 100, a plurality of bearing boxes 200 are fixedly arranged on the rotating disc 100 in a circumferential direction, and a bag making device 300, a dispensing device 400, a bag opening shaping and sealing device 500 and a separation and bag falling device 600 are arranged in the rotating direction of the rotating disc 100. In use, each bearing box 200 rotates with the rotating disc 100, the bag making device 300 can make a packaging bag 700 from a packaging bag film, when the bearing box 200 passes through the bag making device 300, the bag making device 300 can place the made packaging bag 700 in the bearing box 200 in a form with an opening upward; then the bearing box 200 rotates to the dispensing device 400, the dispensing device 400 can quantitatively fill traditional Chinese medicine particles into the packaging bag 700 in the bearing box 200 (the packaging bag 700 is quantitatively filled with different compatible components of traditional Chinese medicine particles by a plurality of dispensing devices 400 to complete the dispensing and filling of traditional Chinese medicine formula particles); then, the packaging bag 700 which completes the quantitative dispensing and filling rotates with the bearing box 200 to below the bag opening shaping and sealing device 500, the bag opening shaping and sealing device shapes and seals the opening part at the top of the packaging bag 700; then, the packaging bag 700 which is sealed at the top rotates with the bearing box 200 to the separation and bag falling device 600, the separation and bag falling device 600 opens the bottom of the bearing box 200 and presses the packaging bag 700 out of the bearing box 200; then, the empty bearing box 200 rotates with the rotating disc 100 to below the bag making device 300, the above working process is repeated to realize continuous dispensing production. The synchronous and efficient traditional Chinese medicine particle quantitative dispensing equipment integrates bag making, quantitative dispensing and filling and packaging shaping, can realize whole-process dispensing production of bagged traditional Chinese medicine particle products, the bag making device 300, the dispensing device 400, the bag opening shaping and sealing device 500 and the separation and bag falling device 600 are arranged along the circumference of the rotating disc 100, the whole equipment structure is compact, occupies small space, the actions of each device are smooth, and continuous dispensing production can be realized, and the production efficiency is high.

[0047] In implementation:

[0048] The structure of the bearing box 200 is as follows Figure 2As shown, it comprises a box body 210 and a bottom support 220. The box body 210 is fixedly connected with the rotating disc 100 and can rotate with the rotating disc 100. The box body 210 is provided with a shaping hole 230 from top to bottom. The height of the box body 210 is less than the height of the packaging bag 700, and the shaping hole 230 is adapted to the shape of the packaging bag 700. The bottom support 220 is rotatably connected with the box body 210. The bottom support 220 is provided with a supporting groove 221, which is arranged below the shaping hole 230 and is adapted to the bottom foot of the packaging bag 700. When the carrying box 200 is used to fix the packaging bag 700, the packaging bag 700 with a closed bottom and side and an open top is inserted into the shaping hole 230 because the shaping hole 230 is adapted to the shape of the packaging bag 700. Because the height of the box body 210 is less than the height of the packaging bag 700, the bottom of the packaging bag 700 is below the box body 210, and the bottom foot of the packaging bag 700 is clamped into the supporting groove 221 and is lifted, and the top opening of the packaging bag 700 is above the box body 210.

[0049] During the conveying and dispensing and filling process, the bottom foot of the packaging bag 700 is lifted by the bottom support 220, and the packaging bag 700 can be conveyed forward with the box body 210. During the filling of the material, the opening position of the packaging bag 700 is positioned by the shaping hole 230 because the shape of the packaging bag 700 is adapted to the shape of the shaping hole 230, so that the relative position of the packaging bag 700 and the box body 210 is fixed. Because the box body 210 is fixedly installed on the rotating disc 100, the conveying speed of the rotating disc 100 only needs to be matched with the filling period of the filling mechanism to accurately align and fill, and no additional righting or positioning mechanism needs to be arranged for the bag opening of the packaging bag. Meanwhile, as the subsequent dispensing and filling is performed, the material is gradually filled in the packaging bag 700 according to the shape of the shaping hole 230, and preliminary shaping can be performed.

[0050] When the packaging bag is separated and dropped after the top is sealed, the bottom support 220 is lifted to be turned outward, driving the supporting groove 221 to be turned and separated from the bottom foot of the packaging bag 700. Then, the top of the packaging bag 700 is pressed downward, and the packaging bag 700 is squeezed out of the shaping hole 230, so that the dropping and separating of the packaging bag can be completed. In this process, on the one hand, the overall shaping of the packaging bag 700 is completed when the packaging bag is pressed downward because the shape of the shaping hole 230 is adapted to the shape of the packaging bag 700, and no additional shaping process is needed after the packaging bag is dropped. On the other hand, in the separation and dropping of the packaging bag by relying on the self-weight in the prior art, the packaging bag 700 is inevitably subjected to the friction and blocking of the inner wall of the carrying box (or tray), and the falling speed of each packaging bag 700 is different due to the different influences of the blocking and lag. However, the falling time of the packaging bag can be directly controlled according to the pressing time by the pressing and dropping of the packaging bag, so that the rhythm of continuous production is ensured.

[0051] In a specific implementation, the bottom support 220 includes a lever, a supporting piece and a torsion spring 222, the lever is fixedly connected with the supporting piece, and the supporting groove 221 is arranged on the supporting piece; the hinge seat 211 is fixedly arranged on the box body 210, one end of the lever is rotatably connected with the hinge seat 211, and the torsion spring is arranged between the lever and the hinge seat 211; one side of the supporting piece, which faces the center of the box body 210, is in abutment with the hinge seat 211, and one end of the supporting groove 221, which faces the center of the box body 210, is open. In a natural state, the torsion spring 222 pulls the lever tightly to position the supporting piece in abutment with the hinge seat 211, at this time, the supporting groove 221 is located below the shaping hole 230 and can hold up the bottom foot of the packaging bag 700. The end of the lever, which is away from the hinge seat 211, is obliquely arranged away from the box body 210, when it is necessary to turn over the supporting piece, the bottom support 220 can be turned up and opened only by lifting the lever upward. Further, the supporting piece has two, and the two supporting pieces are symmetrically arranged on both sides of the bottom of the box body 210 and are used for supporting the two bottom feet of the packaging bag 700 at the same time. Further, the cross section of the shaping hole 230 is olive-shaped in the middle and rectangular at both ends, when the packaging bag 700 is inserted and fixed, the two side edges of the packaging bag 700 are clamped and arranged in the rectangular hole regions at both ends of the shaping hole 230, and are positioned and centered, and when filling, the material fills the olive-shaped region in the middle of the shaping hole 230 to complete the preliminary shaping of the product; the cross section of the supporting groove 221 is V-shaped, when the packaging bag 700 is inserted and fixed, the supporting groove 221 can guide the two ends of the bottom sealing edge of the packaging bag 700 to complete the positioning and centering of the packaging bag 700 in the box body 210. A plurality of mounting holes 212 are further arranged on the box body 210, which facilitates the fixation of the box body 210 on the turntable 100 through bolts, screws and the like; a plurality of reinforcing rib plates are further arranged on the box body 210 to improve the rigidity of the box body 210 and maintain the shape of the box body 210 and the shaping hole 230. In actual application, a plurality of shaping holes 230 can be arranged on the box body 210, the plurality of shaping holes 230 are arranged in sequence along the thickness direction of the packaging bag 700, and the bottom ends of the plurality of shaping holes 230 are provided with the supporting grooves 221, so that simultaneous conveying, filling and separating and falling of a plurality of packaging bags can be realized to improve production efficiency. The application embodiment shown in the drawing is a double-bag simultaneous dispensing production application.

[0052] The above bag making device 300 is as follows Figure 3As shown, it comprises a bag forming frame 310 for forming a packaging film roll, a linkage sealing mechanism 320 comprising a vertical sealing strip 321 and a bottom sealing strip 322 for bottom sealing and side sealing of the packaging film at the lower part of the bag forming frame, a top bag piece arranged at the lower end of the bag forming frame and capable of moving up and down, and a counter cutter 330 arranged at the lower end of the bag forming frame for cutting the packaging film. When the bag making device 300 makes a bag, the packaging film is first wrapped around the bag forming frame 310 to form a packaging film roll; then the vertical sealing strip 321 and the bottom sealing strip 322 of the linkage sealing mechanism 320 are controlled to move towards the bag forming frame 310, the vertical sealing strip 321 can side seal the packaging film at the lower part of the bag forming frame 310, and the bottom sealing strip 322 can bottom seal the bottom end of the packaging film at the bottom of the bag forming frame 310; then the top bag piece is moved downward, the top bag piece can drive the whole bottom sealed packaging film to move downward; then the top bag piece is lifted, the counter cutter 330 cuts the bottom end of the packaging film pushed downward by the top bag piece, and separates an independent packaging bag 700; the above working process is repeated to continuously make bags.

[0053] The specific structure of the bag making device 300 is applied to the present application, the top bag piece is arranged directly below and opposite to one of the carrying boxes 200, and when the bottom sealed packaging film is driven to move downward, the top bag piece can also directly place the part of the packaging film at the lower part which is bottom sealed and side sealed (i.e. the independent packaging bag 700 separated by the counter cutter 330 subsequently) into the shaping hole 230 of the carrying box 200, to complete the alignment and placement process of the packaging bag 700 into the carrying box 200. Further, the top bag piece is adapted to the shape of the shaping hole 230, and when the top bag piece pushes the packaging bag 700 into the carrying box 200, it can also open the bag opening of the packaging bag 700. Overall, in the synchronous and efficient traditional Chinese medicine particle quantitative dispensing equipment, the bag making device 300 simultaneously has the functions of continuous bag making, alignment and bag placing, and bag opening, without the need for additional devices for placing packaging bags and opening bag openings, the overall integration of the equipment is high, the occupied space is small, and there is no additional placement of packaging bags and opening of bag openings, which is conducive to ensuring the efficient and rapid production rhythm.

[0054] The above dispensing device 400 can use any device on the market that can realize the quantitative filling of solid particle materials, which will not be described in detail here. A bag opening alignment detection mechanism 800 is also arranged between the bag making device 300 and the dispensing device 400, such as Figures 4 to 6As shown, the bag opening adjustment detection mechanism 800 includes a bagging assembly 810 and an opening detection assembly 820 arranged in sequence along the rotation direction of the rotating disc 100. The bagging assembly 810 is arranged above the rotating disc, and is used to push the opening of the packaging bag 700 passing below the bagging assembly 810. The opening detection assembly 820 is used to detect the opening position and width of the packaging bag 700 after being pushed by the bagging assembly 810. In use, when the rotating disc 100 drives the packaging bag 700 to pass below the bagging assembly 810, the bagging assembly 810 blocks the front of the bag opening of the packaging bag 700. As the rotating disc 100 continues to move forward, the top bag opening of the packaging bag 700 is bent and then returns to the original position after passing the bagging assembly 810. The whole process is equivalent to that the bag opening of the packaging bag 700 is hit once by the bagging assembly 810, and the hitting process can open the bag opening of the packaging bag 700 which is not completely opened. Then, the rotating disc 100 drives the packaging bag 700 to the position of the opening detection assembly 820, and the opening detection assembly 820 detects the opening position of the packaging bag 700. If the bag opening of the packaging bag 700 is opened beyond the set position, the rotating disc 100 continues to move forward and enters the subsequent filling process. If the bag opening of the packaging bag 700 is not opened to the set position, the rotating disc 100 reverses and drives the packaging bag 700 to retreat to the bagging assembly 810 and then moves forward again (the bag opening is hit once when the packaging bag 700 retreats to pass the bagging assembly 810, and the bag opening is hit once again when the packaging bag 700 moves forward to pass the bagging assembly 810 again), until the opening detection assembly 820 detects that the bag opening of the packaging bag 700 is opened beyond the set position, and then the rotating disc 100 continues to move forward.

[0055] The opening detection assembly 820 includes a detection assembly mounting seat 821 and two sets of reflection switches 822 arranged side by side. The reflection switches 822 are arranged to face the side of the bag opening of the packaging bag passing the position of the opening detection assembly 820. The two sets of reflection switches 822 are arranged on both sides of the extension line of the width direction of the packaging bag 3, and the distance between the two sets of reflection switches 822 is matched with the filling space required by the subsequent dispensing device 400. Figure 6 As shown, the two sets of reflection switches 822 respectively determine whether the left and right sides of the packaging bag 700 are opened to the set position. Only when Figure 6 As shown in the lower packaging bag in the middle, when the rays of the two sets of reflection switches 822 are all blocked by the bag opening of the packaging bag 700, it indicates that the bag opening of the packaging bag 700 is opened beyond the set position, and the packaging bag 700 can be smoothly dispensed and filled after moving to the dispensing device 400. When the rays of any one of the two sets of reflection switches 822 are not blocked, it indicates that the bag opening of the packaging bag 700 is not opened to the set position, and the packaging bag 700 needs to be retreated to the bagging assembly 810 for hitting and adjustment. Figure 6 As shown in the upper packaging bag 700 in the middle, it is the case that the rays of the reflection switches are not blocked on both sides of the packaging bag 700.

[0056] In specific implementation, the bagging assembly 810 includes a bagging mounting member 811, a bagging member 813, and a pressing plate 812. The pressing plate 812 is fixedly connected with the bagging mounting member 811 by bolts. The bagging member 813 is clamped between the pressing plate 812 and the bagging mounting member 811. The bagging member 813 has a simple mounting structure, and the clamping position of the bagging member 813 can be conveniently adjusted to meet the requirement that most of the packaging bags 700 are opened to more than a set position by one beating of the bagging member 813 during debugging, so as to meet the subsequent filling requirement and reduce the frequency of reverse rotation of the rotating disc 100. Similarly, the opening detection assembly 820 can be provided in several numbers, and the several opening detection assemblies 820 are arranged side by side to be suitable for the situation of simultaneous conveying and filling of multiple packaging bags 700, such as the application embodiment of simultaneous conveying and filling of double bags shown in the drawing.

[0057] The structure of the bag opening shaping and sealing device 500 is shown in Figures 7 to 12 The bag opening shaping and sealing device 500 includes a mounting member, an elastic member, a driving mechanism, a sealing mechanism, and a shaping mechanism. A first sliding seat 501 and a second sliding seat 502 are sequentially and slidably arranged on the mounting member. The sliding directions of the first sliding seat 501 and the second sliding seat 502 are the same. The first sliding seat 501 is connected with the second sliding seat 502 through the elastic member. The driving mechanism is used to drive the second sliding seat 502 to slide. The shaping mechanism includes a shaping groove 503. The shaping groove 503 is fixedly arranged on the first sliding seat 501. The shaping groove 503 is arranged along the sliding direction of the first sliding seat 501. One end of the shaping groove 503 away from the second sliding seat 502 is open. The open end of the shaping groove 503 is arranged opposite to the side edge of the opening part of the packaging bag 700 in one of the bearing boxes. In implementation, the shaping groove 503 can be directly formed on the first sliding seat 501, or two parallel shaping strips can be installed on the first sliding seat 501 as shown in the drawing. The shaping groove 503 is formed between the two shaping strips. The sealing mechanism includes a top sealing heating strip 504, a top sealing rubber strip 505, a top sealing lever 506, and a top sealing guide groove 507. The top sealing heating strip 504 is slidably arranged on the first sliding seat 501. The sliding direction of the top sealing heating strip 504 is perpendicular to the sliding direction of the first sliding seat 501. The top sealing rubber strip 505 is fixedly arranged on the first sliding seat 501. The top sealing heating strip 504 is arranged opposite to the top sealing rubber strip 505. A sealing groove is formed between the top sealing heating strip 504 and the top sealing rubber strip 505. The sealing groove is arranged opposite to the shaping groove 503. The top sealing guide groove 507 is arranged on the second sliding seat 502. One end of the top sealing lever 506 is slidably arranged in the top sealing guide groove 507. The other end of the top sealing lever 506 is fixedly connected with the top sealing heating strip 504. The top sealing guide groove 507 is formed as an arc-shaped groove. When the second sliding seat 502 approaches the first sliding seat 501, the top sealing heating strip 504 can be driven to approach the top sealing rubber strip 505 through the top sealing lever 506.

[0058] The working process of the shaping and sealing device 500 is shown in Figures 7 to 9As shown, in the return state, the second slide 502 is located at the left end of the entire device, the first slide 501 is located at the middle of the device to avoid each bearing box 200, and the packaging bag 700 can be smoothly conveyed under the rotation of the turntable 100; when it is necessary to shape and seal the packaging bag 700, the turntable 100 stops running, the driving mechanism drives the second slide 502 to slide to the right, and under the pushing of the elastic member (spring), the first slide 501 slides to the right, and when passing through the position of the packaging bag 700, the opening edge of the packaging bag 700 is clamped into the shaping groove 503, and in the process of continuous sliding of the first slide 501, the shaping groove 503 gradually combs the opening edge of the packaging bag (it needs to be explained here that, due to the setting of the elastic member, the sliding of the first slide 501 is not rigid sliding in the process of combing and shaping, and it has the effect of flexible oscillation combing), until the first slide 501 slides to the right end of the device and is limited, at this time, the bag opening shaping is completed; then the driving mechanism continues to drive the second slide 502 to move to the right, the elastic member is compressed, and the second slide 502 approaches the first slide 501, at this time, under the guidance of the top sealing guide groove 507, the top sealing lever 506 drives the top sealing heating strip 504 to approach the top sealing rubber strip 505, until the bag opening of the packaging bag 700 is clamped between the top sealing heating strip 504 and the top sealing rubber strip 505 to complete the sealing; after the sealing is completed, the driving mechanism reverses the operation to drive the second slide 502 to slide to the left, and under the pulling of the elastic member, the first slide 501 moves to the left together, and both return to the original position. Figure 1 As shown in the return state, the turntable 100 continues to run, thereby completing a shaping and sealing action.

[0059] As can be seen from the above working process, the entire shaping and sealing action can be continuously completed only by driving the second slide 502 to continuously slide forward by the driving mechanism, and after the sealing is completed, the second slide 502 is reversely driven to return the device, which is simple to control and continuous in action, and the production rhythm is more compact, which is beneficial to realize continuous high-speed production. It also needs to be explained that the first slide 501 and the second slide 502 are connected through the elastic member, and when high-speed feeding occurs, the elastic member also plays a buffering role to avoid rigid impact between the second slide 502 and the first slide 501.

[0060] Furthermore, a limit stop 508 is fixedly installed on the mounting component. The limit stop 508 is adapted to the first slide block 501. When the first slide block 501 moves to the right and abuts against the limit stop 508, the opening edge of the packaging bag 700 is completely inserted into the shaping groove 503 and the shaping is completed. At this time, the limit stop 508 blocks and limits the first slide block 501. In specific implementation, the limit stop 508 can be a shock-absorbing sleeve, shock-absorbing pad, etc., to reduce the rigid impact generated by the first slide block 501 during high-speed production. A first position sensor 509 and a second position sensor 510 are also fixedly installed on the mounting component. Both the first position sensor 509 and the second position sensor 510 are adapted to the second slide block 502. When the second slide block 502 moves to... Figure 7 When the slide block 502 moves to the indicated return position, it is sensed by the second position sensor 510; Figure 9 The top sealing heating strip 504 and top sealing adhesive strip 505, when clamping the bag opening to the sealing position, are sensed by the first position sensor 509. By configuring the sensor, a position signal can be provided, facilitating automatic control of the feed speed during the shaping and sealing process through a program, thereby improving continuous production speed. The specific control process is as follows: From... Figure 7 When the return state is shown, and reshaping and sealing are required, the drive mechanism first drives the second slide 502 to move to the right at high speed according to a set time or set step size, so that the first slide 501 approaches the position where the bag opening is inserted into the opening end of the shaping groove 503; then the drive mechanism switches to low speed to drive the second slide 502 to move to the right until the first position sensor 509 senses and emits a signal, at which point the aforementioned reshaping and sealing action is completed; then the drive mechanism pushes the second slide 502 to move to the left at high speed according to a set time or set step size; after the set time or set step size, if the second position sensor 510 does not sense and emit a signal, the drive mechanism switches to low speed to drive the second slide 502 to move to the left for compensation, until the second position sensor 510 senses and emits a signal, and the drive mechanism stops operating.

[0061] In practice, photoelectric switches are installed on both sides of the opening end of the shaping groove 503 to detect whether the opening end of the packaging bag 700 is stuck in the shaping groove 503. If the photoelectric switches do not detect a blocked signal, it proves that the opening end of the packaging bag is still open and has not been stuck in the shaping groove 503. The opening end of the shaping groove 503 is also provided with a guide part with an eight-shaped opening, which can smoothly guide the opening end of the packaging bag into the shaping groove 503. A bag mouth guide plate is provided above the guide part. One end of the bag mouth guide plate is fixedly connected to the first slide 501 and moves with the first slide 501. During shaping and sealing, the bag mouth guide plate can press down the packaging bag that is too high to facilitate the subsequent shaping and sealing operation.

[0062] Similarly, as shown in the application embodiment of the double-bag simultaneous conveying and filling, the aforementioned shaping mechanism and sealing mechanism are both provided with two, and the two shaping mechanisms and the two sealing mechanisms are both symmetrically arranged along the center line of the first sliding seat 501, so that the shaping and sealing of two packaging bags can be completed simultaneously in one action. It should be understood that, since the transverse (perpendicular to the sliding direction of the first sliding seat 501) dimension of the shaping mechanism and the sealing mechanism is small, if necessary, several can be arranged side by side to meet the shaping and sealing needs of multiple rows of packaging bags for simultaneous filling and conveying, thereby improving the production efficiency.

[0064] The working process of the separating and falling bag device 600 when separating and falling the bags is as follows: The working process of the separating and falling bag device 600 when separating and falling the bags is as follows:

[0065] S1, when the carrier box 200 is carried to the position between the lower pressing plate 601 and the lifting seat 602 by the rotating disc 100, the rotating disc 100 is paused;

[0066] S1, when the carrier box 200 is carried to the position between the lower pressing plate 601 and the lifting seat 602 by the rotating disc 100, the rotating disc 100 is paused;

[0067] S2, the driving mechanism drives the driving shaft 603 to rotate, in the process of the follower 605 passing through the push section of the cam 604, the lifting seat 602 rises, the bottom support 220 is lifted to turn and open;

[0068] S3, the driving mechanism drives the driving shaft 603 to continue to rotate, in the process of the follower 605 passing through the circular arc maintaining section of the cam 604, the lifting seat 602 is maintained at the highest position to maintain the bottom support 220 of the carrying box 200 in a fully open state, and in this process, the lower pressing plate 601 completes a descending and rising action, and when the lower pressing plate 601 is pressed downward, the packaging bag 700 can be extruded out of the carrying box 200;

[0069] S4, the driving mechanism drives the driving shaft 603 to continue to rotate, in the process of the follower 605 passing through the return section 42 of the cam 604, the lifting seat 602 descends and is separated from the bottom support 220, and the bottom support 220 is reset under the action of the torsional spring;

[0070] S5, the turntable 100 starts to forward transport until the next carrying box 200 is carried to the position between the lower pressing plate 601 and the lifting seat 602, and the processes of S1-S4 are repeated.

[0071] As can be seen from the above working process, the separation and bag falling device 600 can drive the lifting and descending actions of the lower pressing plate 601 and the lifting seat 602 through a single power input driving shaft 603, and under the design of the foregoing structure, the lower pressing plate 601 and the lifting seat 602 are asynchronous and realize bidirectional separation and bag falling. Specifically, the bottom of the carrying box 200 is in an open state by lifting the bottom support 220 with the lifting seat 602, at which time the bottom of the packaging bag 700 is separated from the bottom of the carrying box 200; then the lifting seat 602 maintains the open state, and the lower pressing plate 601 extrudes the packaging bag 700 out of the carrying box 200, so that the packaging bag 700 is separated from the carrying box 200 as a whole, and in the process of extruding the packaging bag 700 out of the carrying box 200, the packaging bag 700 is also shaped by relying on the shaping hole, so that the product is more regular and beautiful; then the lifting seat 602 descends to close the bottom of the carrying box 200. In actual application, if the driving shaft 603 is continuously rotated, the separation and bag falling device 600 will execute the action of “lifting the lifting seat 602, maintaining the lifting seat 602 at the highest position while the lower pressing plate 601 completes a pressing and rising action, and lowering the lifting seat 602” according to the rotation speed of the driving shaft 603 in a certain period, and if the cycle period matches the transport rhythm of the turntable 100, the automatic separation and bag falling can be realized at the end of the bagged product production line, and the structure and control are relatively simple.

[0072] The aforementioned "the end of the crank 606 away from the driving shaft 603 is matched with the pressing plate 601, and the pressing plate 601 completes a descending and ascending action in the process of keeping the lifting seat 602 at the highest point", can be realized in various structural forms, for example: the end of the crank 606 away from the driving shaft 603 is rotatably connected with a connecting rod, and the other end of the connecting rod is rotatably connected with the pressing plate 601, so that the crank 606, the connecting rod and the pressing plate 601 form a crank-connecting rod-slider mechanism, and when the crank 606 rotates one circle, the pressing plate 601 completes a descending and ascending action. Through specific size and position design, the follower 605 can be located in the middle of the circular arc keeping section of the cam 604 when the pressing plate 601 is at the lowest point, which can meet the aforementioned "the pressing plate 601 completes a descending and ascending action in the process of keeping the lifting seat 602 at the highest point". This will not be described in detail here. In the implementation of the embodiment, a first elastic member and a target plate 609 are further provided, the first elastic member is used to apply an upward elastic force to the pressing plate 601, the target plate 609 is fixedly connected with the pressing plate 601, and the end of the crank 606 away from the driving shaft is provided with a tapping member matched with the target plate 609. As shown in Figure 15 Fig. 6 shows a state diagram when the follower 605 is located at the starting position of the circular arc keeping section of the cam 604 in the counterclockwise rotation process of the driving shaft 603, at this time, the tapping member starts to contact the target plate 609; in the process of continuing to rotate the driving shaft 603 counterclockwise, the tapping member rotates with the crank 606, and pushes down the target plate 609, thereby driving the entire pressing plate 601 to move downward; as shown in Figure 16 Fig. 7 shows a state diagram when the follower 605 rotates to the end position of the circular arc keeping section 40 of the cam 604, when the driving shaft 603 continues to rotate to this state, the tapping member moves to the end of the target plate 609; as shown in Figure 17 Fig. 8 shows a state diagram when the follower 605 enters the return section 42 of the cam 604, when the driving shaft 603 continues to rotate to this state, the tapping member is separated from the target plate 609, and the pressing plate 601 quickly rebounds and resets under the action of the first elastic member. The whole structure is compact, occupies small space, the pressing plate 601 can quickly rebound and reset after completing the pressing, avoids interference and blockage to the subsequent packaging bag, and is beneficial to the rapid connection of the rotating disc 100 and the separation and bag falling device 600.

[0073] In actual production process, the time of starting the rotary disc 100 after completing the bagging does not necessarily wait for the lifting seat 602 to completely descend, and only needs to confirm that the packaging bag 700 has been separated to complete the bagging to start the rotary disc 100 to forwardly convey, so that the step time of conveying and the descending time of the lifting seat 602 are overlapped, thereby further improving the production speed and efficiency. Further, the inductive switch 613 is arranged on the lifting seat 602, and the inductive switch 613 is used to detect the bagging condition of the packaging bag 700. For example, the inductive switch 613 is selected to be a pair of shot switches, which are arranged opposite to the bagging path below the packaging bag 700, and when the signal of the pair of shot switches changes from no to yes and then to no, it proves that the packaging bag 700 has been successfully bagged.

[0074] It should be noted that the foregoing is the working process description when the driving shaft 603 rotates in one direction. The separation and bagging device 600 can also rotate the driving shaft 603 in the reverse direction according to the needs in actual application, which should also be within the concept of the present application. Specifically, the working process is as follows: first, rotate the driving shaft 603 counterclockwise to drive the lifting seat 602 to rise to the position shown in FIG. 6A; then continue to rotate the driving shaft 603 counterclockwise, maintain the position of the lifting seat 602 unchanged, and lower the lower pressing plate 601 to the position shown in FIG. 6B; then reverse the driving shaft 603 to rotate clockwise, and in the rotating process, the driven part 605 can continue to be attached to the circular arc maintaining segment of the cam 604 to maintain the position of the lifting seat 602 unchanged, and the striking part is reversely rotated with the crank 606, the lower pressing plate 601 is raised to the position shown in FIG. 6A under the action of the first elastic part; then continue to rotate the driving shaft 603 clockwise, and in the process of the driven part 605 reversely passing through the pushing segment of the cam 604, the lifting seat 602 gradually descends. Figure 15 Figure 16 It should be noted that the foregoing is the working process description when the driving shaft 603 rotates in one direction. The separation and bagging device 600 can also rotate the driving shaft 603 in the reverse direction according to the needs in actual application, which should also be within the concept of the present application. Specifically, the working process is as follows: first, rotate the driving shaft 603 counterclockwise to drive the lifting seat 602 to rise to the position shown in FIG. 6A; then continue to rotate the driving shaft 603 counterclockwise, maintain the position of the lifting seat 602 unchanged, and lower the lower pressing plate 601 to the position shown in FIG. 6B; then reverse the driving shaft 603 to rotate clockwise, and in the rotating process, the driven part 605 can continue to be attached to the circular arc maintaining segment of the cam 604 to maintain the position of the lifting seat 602 unchanged, and the striking part is reversely rotated with the crank 606, the lower pressing plate 601 is raised to the position shown in FIG. 6A under the action of the first elastic part; then continue to rotate the driving shaft 603 clockwise, and in the process of the driven part 605 reversely passing through the pushing segment of the cam 604, the lifting seat 602 gradually descends. Figure 15

[0075] In specific implementation, the striking part uses the roller 610, which is rotatably connected with the crank 606 to reduce the wear of itself and the target plate 609. The separation and bagging device 600 further includes an upper sliding seat 611 and two parallelly arranged guide rails 614, the upper sliding seat 611 is slidably connected with the two guide rails 614, and the lower pressing plate 601 is installed on the upper sliding seat 611; the first elastic part is selected to be two first springs 607, the two first springs 607 are respectively sleeved on the two guide rails 614, the lower end of the first spring 607 is fixed, and the upper end of the first spring 607 is fixedly connected with the upper sliding seat 611.

[0076] ​​The aforementioned fitting of the follower 605 and the cam 604 can adopt different locking forms of cam mechanisms, such as a form-locking cam mechanism in which a groove is machined on the wheel surface of the cam 604 and the follower 605 is slidingly arranged in the groove. In the embodiment, a force-locking cam mechanism is arranged for the purpose of structural simplification and cost control, i.e., the follower 605 is arranged directly above the driving shaft 603 to form a gravity closed-locking form, and the follower 605 can be kept in close contact with the cam 604 under the action of the weight of the lifting seat 602. Further, a second elastic member is arranged to apply a downward elastic force to the lifting seat, further forming a spring closed-locking form, and ensuring the close contact reliability of the follower 605 and the cam 604. In the specific implementation, the bag separating and falling device 600 further comprises a sliding seat 612 and two parallel arranged guide rails 614, the sliding seat 612 is slidingly connected with the two guide rails 614, and the lifting seat 602 is installed on the sliding seat 612; the second elastic member is a second spring 608, and the two second springs 608 are sleeved on the two guide rails 614, the upper end of the second spring 608 is fixed, and the lower end of the second spring 608 is fixedly connected with the sliding seat 612.
