Description

Technical Field

[0001] The present invention belongs to the technical field of packaging machines, and particularly relates to an integrated mechanism. Background Art

[0002] In the process of bagging materials in a packaging bag, it is necessary to open the bag, expand the bag, and feed the materials. Usually, these several process steps are realized by different action mechanisms, which makes the overall structure of the packaging machine bloated and not conducive to miniaturization. Since different process steps are completed by different action mechanisms, the correlation between each process step is not strong and precise control is required, resulting in high debugging costs. Moreover, when one of the action mechanisms fails, the other action mechanisms cannot stop in time, which easily causes movement interference and collision, further expanding the loss. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention discloses an integrated mechanism, which adopts one power source and drives at least two action mechanisms in a linkage manner, effectively reducing the volume of the packaging machine, making the connection between each process step stable. At the same time, when one of the action mechanisms fails, it can achieve timely parking and avoid expanding losses.

[0004] The specific technical solution of the present invention is as follows:

[0005] An integrated mechanism, comprising:

[0006] An expanding bag assembly and an opening bag assembly;

[0007] A driving assembly, the driving assembly divides into a first power output and a second power output, the first power output drives the opening bag assembly to open and close to open the bag mouth of the packaging bag, and the second power output drives the expanding bag assembly to switch between an expanding bag position and an avoidance position; and

[0008] A base, the expanding bag assembly and the opening bag assembly are movably arranged on the base;

[0009] Wherein, the expanding bag assembly also follows the opening and closing of the opening bag assembly, so as to form a feeding channel at the expanding bag position after the bag mouth of the packaging bag is opened.

[0010] The movement of the driving assembly can realize the first power output and the second power output, use two powers to drive the expanding bag assembly and the opening bag assembly to move synchronously, and realize the avoidance of the expanding bag assembly in the corresponding process actions. Therefore, in the actual process actions of opening the bag and expanding the bag, it can avoid the interference between the expanding bag assembly and the packaging bag, resulting in the inability of the opening bag assembly to perform the bag opening operation well; on this basis, the process linkage of expanding the bag and opening the bag is improved well, and based on the same power source, the volume of the equipment is effectively reduced, and the additional losses caused by accidental failures are avoided.

[0011] Preferably, a linkage mechanism is provided between the bag opening assembly and the bag supporting assembly. The linkage mechanism includes a first connecting portion for cooperating with the first power output and a second connecting portion for cooperating with the second power output. The bag opening assembly is connected to the first connecting portion, and the bag supporting assembly is connected to the second connecting portion;

[0012] The first connecting portion is movably engaged with the base in the opening and closing direction of the bag opening assembly, and the second connecting portion is movably engaged with the base in a direction perpendicular to the opening and closing direction of the bag opening assembly;

[0013] The bag supporting assembly is slidably engaged with the second connecting portion in its opening and closing direction, and the bag supporting assembly and the bag opening assembly are slidably engaged in a direction perpendicular to the opening and closing direction.

[0014] This application is provided with a linkage mechanism. Through the linkage mechanism, the relative movements of the bag opening assembly and the bag supporting assembly have a linkage relationship, thereby improving the movement correlation of bag opening and bag supporting.

[0015] Preferably, a first guiding portion and a second guiding portion which are connected to each other are provided on the base, and the first connecting portion is movably engaged with the first guiding portion and the second guiding portion respectively;

[0016] The first connecting portion moves along the first guiding portion to drive the bag opening assembly to open and close; when the first connecting portion moves to the end of the first guiding portion, the first connecting portion transitions to the second guiding portion and moves in a direction non-collinear with the opening and closing direction of the bag opening assembly, so as to cause a spatial displacement for the bag opening assembly to avoid interference.

[0017] The second guiding portion can cause a spatial displacement for the bag opening assembly to avoid interference. At this time, the bag opening assembly avoids the packaging bag. The packaging bag itself is transported to the lower side / inner side of the integrated mechanism through the clamping assembly. Therefore, before opening the bag, it is necessary to adjust the position of the bag opening assembly so that at least a part of the bag opening of the packaging bag can be located at a preset bag opening position.

[0018] Preferably, the driving assembly includes:

[0019] A first driving member for the first power output; and

[0020] A second driving member for the second power output;

[0021] Wherein, the first driving member includes a first power member, a second power member, and a third power member. One end of the second power member is hinged to the first power member, and the other end is hinged to the third power member. The third power member is movably connected to the bag opening assembly, and the third power member is also hinged to the base;

[0022] The first power member receives the first power output and moves linearly, transmits the first power output to the third power member through the second power member, and causes the third power member to swing, so as to drive the bag opening assembly to open and close.

[0023] This structure is simple and compact, with a concise power transmission path, and can well achieve the coordinated cooperation between the bag-opening component and the bag-supporting component.

[0024] Preferably, the driving component further includes:

[0025] A driving part one and a driving part two that are separated from each other. The driving part one and the driving part two rotate coaxially, and both are in a closed-loop guiding and driving structure. The driving part one is movably matched with the driving part one, and the driving part two is movably matched with the driving part two.

[0026] This structure is simple, can well achieve power output, and enables the movements between the driving part one and the driving part two not to interfere with each other.

[0027] Preferably, the driving part one has an opening and holding section, a preparation section, a closing movement section, and an opening movement section that are connected end to end;

[0028] The opening and holding section is an arc with the rotation axis as the center of the circle;

[0029] In the direction where the driving part one transitions from the opening and holding section to the closing movement section, the distance from the preparation section to the rotation axis first decreases and then increases;

[0030] In the direction where the driving part one transitions from the preparation section to the opening movement section, the distance from the closing movement section to the rotation axis increases;

[0031] In the direction where the driving part one transitions from the closing movement section to the opening and holding section, the distance from the opening movement section to the rotation axis decreases;

[0032] The driving part two has a position holding section one, a displacement section one, and a position holding section two that are connected end to end;

[0033] Both the position holding section one and the position holding section two are arcs with the rotation axis as the center of the circle, and the diameter of the position holding section two is larger than that of the position holding section one;

[0034] In the direction where the driving part two transitions from the position holding section one to the position holding section two, the distance from the displacement section one to the rotation axis increases.

[0035] This structural setting can well meet the specific process requirements. Since in the direction where the driving part one transitions from the closing movement section to the opening and holding section, the distance from the opening movement section to the rotation axis decreases, when the driving part one moves in the closing movement section, it has the ability to move in different directions, thus avoiding interference between the bag-opening component and the packaging bag.

[0036] Preferably, it further includes a blanking component, and the blanking component is movably arranged on the base;

[0037] The driving assembly also outputs a third power. When the third power output drives the blanking assembly to form a blanking channel, it extends into the packaging bag for blanking.

[0038] In this application, the blanking assembly can be driven to move by the same power source, thereby further reducing the volume of the equipment and better avoiding additional losses caused by accidental failures.

[0039] Preferably, the driving assembly further includes:

[0040] A third driving member for the third power output; and

[0041] A third driving part separated from the first driving part and the second driving part. The third driving part rotates coaxially with the first driving part. The third driving part has a closed-loop guiding and driving structure, and the third driving part is movably matched with the third driving member.

[0042] This structure is simple, can well achieve power output, and enables the movements of the first driving member, the second driving member, and the third driving member not to interfere with each other.

[0043] Preferably, the third driving part has a third position-holding section, a second displacement section, and a fourth position-holding section that are connected end to end;

[0044] Both the third position-holding section and the fourth position-holding section are arcs with the rotation axis as the center of the circle. The diameter of the fourth position-holding section is larger than that of the third position-holding section;

[0045] In the direction where the third driving member transitions from the fourth position-holding section to the third position-holding section, the distance from the second displacement section to the rotation axis decreases, and the second displacement section has at least one first rapid-drop portion.

[0046] This structural setting can well meet the specific process requirements; the first rapid-drop portion can cause the blanking assembly to shake, so that the material can better enter the packaging bag.

[0047] Preferably, the bag-opening assembly includes a first bag-opening mechanism and a second bag-opening mechanism arranged oppositely, the bag-supporting assembly includes a first bag-supporting mechanism and a second bag-supporting mechanism arranged oppositely, the first bag-opening mechanism and the first bag-supporting mechanism are on the same side, and the second bag-opening mechanism and the second bag-supporting mechanism are on the same side;

[0048] Among the first bag-supporting mechanism and the second bag-supporting mechanism, any one is provided with a limiting member facing the other, and the limiting members provided by the two are separated or abutted as the bag-opening assembly opens and closes;

[0049] A guiding member is arranged between the bag-opening mechanism and the bag-supporting mechanism on the same side, and an elastic member is sleeved on the guiding member.

[0050] When the two limit members abut against each other, further movement of the driving assembly can compress the elastic member. Then, when the bag supporting mechanism I and the bag supporting mechanism II remain stationary, the bag opening mechanism I and the bag opening mechanism II can achieve further movement, thereby realizing the bag opening of the packaging bag. During the next movement process, the elastic member on either side releases the stored energy, driving the bag opening mechanism and the bag supporting mechanism on the same side to return to their original relative positions, thus meeting the bag supporting requirements.

[0051] Compared with the prior art, the present invention can realize the movement of multiple action mechanisms through one power source, thereby improving the movement linkage of different technological processes. At the same time, the volume of the equipment is reduced, which is beneficial to the miniaturization of the equipment. In addition, when any one of the action mechanisms fails, the power source can stop, effectively avoiding additional losses. Therefore, the present invention does not need to separately design complex independent transmission systems for different action mechanisms, making the entire mechanical transmission system more concise and easy to maintain and manage.

Detailed implementation manners

[0061] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the specific implementation manners.

[0062] As Figures 1 to 4 shown, an integrated mechanism includes a bag supporting assembly 1, a bag opening assembly 2, a driving assembly 3, and a base 4; the driving assembly 3 outputs a first power and a second power, the first power output drives the bag opening assembly 2 to perform an opening and closing movement to open the bag mouth of the packaging bag, and the second power output drives the bag supporting assembly 1 to switch between a bag supporting position and an avoidance position; the bag supporting assembly 1 and the bag opening assembly 2 are movably arranged on the base 4; the bag supporting assembly 1 also opens and closes following the bag opening assembly 2 to form a material discharging channel at the bag supporting position after the bag mouth of the packaging bag is opened.

[0063] In this embodiment, the integrated mechanism is used for a packaging machine, and the packaging machine is configured with a clamping mechanism for transporting the packaging bag. The clamping mechanism transports the package to the inside of the opened bag opening assembly 2, so that when the bag opening assembly 2 closes, the bag opening of the packaging bag can be realized. Specifically, in this embodiment, the bag opening assembly 2 uses a suction cup 5 to adsorb the packaging bag to open the bag, and the bag supporting assembly 1 uses a pusher 6 to extend into the inside of the packaging bag after the packaging bag is opened and move following the bag opening assembly 2, thereby forming a material discharging channel. After the material discharging channel is formed, materials can be input from the bag mouth of the packaging bag.

[0064] Further, in this embodiment, the bag opening assembly 2 includes a bag opening mechanism 1 and a bag opening mechanism 2 which are arranged opposite to each other, and the bag holding assembly 1 includes a bag holding mechanism 1 and a bag holding mechanism 2 which are arranged opposite to each other, the bag opening mechanism 1 and the bag holding mechanism 1 are on the same side, and the bag opening mechanism 2 and the bag holding mechanism 2 are on the same side; either of the bag holding mechanism 1 and the bag holding mechanism 2 is provided with a stopper 7 facing the other, and the stoppers 7 provided on both are separated or counteracted with the opening and closing movement of the bag opening assembly 2; a guide member is provided between the bag opening mechanism and the bag holding mechanism on the same side, and the guide member is provided with an elastic member 8. When the second power output causes the bag holding assembly 1 to be in the avoidance position ( Figure 7 D), since both the bag-holding mechanism 1 and the bag-holding mechanism 2 are provided with the limiting members 7, the two paddles 6 do not contact each other due to the interference of the two limiting members 7 during the closing process of the bag-holding assembly 1. At this time, the driving assembly 3 continues to operate, so that the bag-holding mechanism 1 and the bag-holding mechanism 2 maintain a relatively static position. Based on the deformation of the elastic member 8, the bag-opening mechanism 1 and the bag-opening mechanism 2 continue to move close to each other until they contact so that the two suction cups 5 respectively adsorb the two sides of the packaging bag, thereby opening the bag mouth of the packaging bag during the opening movement. In this process, the two limiting members 7 also separate from each other. Under the force of the elastic member 8 restoring the deformation, the two paddles 6 move away from each other to restore the original relative position with the suction cup 5 on the same side, and then the second power output causes the bag-holding assembly 1 to be in the bag-holding position ( Figure 7 F), the opened packaging bag is opened. At the same time, it can be seen that the two plectrums 6 are located on the inner sides of the two suction cups 5.

[0065] In this embodiment, a linkage mechanism is provided between the bag opening assembly 2 and the bag holding assembly 1, and the linkage mechanism includes a connection part 1 9 for cooperating with the first power output, and a connection part 2 10 for cooperating with the second power output. The bag opening assembly 2 is connected to the connection part 1 9, and the bag holding assembly 1 is connected to the connection part 2 10; the connection part 1 9 is movably matched with the base 4 in the opening and closing direction of the bag opening assembly 2, and the connection part 2 10 is movably matched with the base 4 in the opening and closing direction perpendicular to the bag opening assembly 2; the bag holding assembly 1 is slidably matched with the connection part 2 10 in its opening and closing direction, and the bag holding assembly 1 and the bag opening assembly 2 are slidably matched perpendicular to the opening and closing direction. The movement of the connection part 1 9 can realize the opening and closing of the bag opening assembly 2 and the bag holding assembly 1, and the movement of the connection part 2 10 realizes the high and low position switching of the bag holding assembly 1. Specifically, the connection part 1 9 and the base 4 are slidably matched in the horizontal direction, and the connection part 2 10 and the base 4 are slidably matched in the vertical direction. Through the sliding matching relationship, the movement path of the connection part 1 9 and the connection part 2 10 is maintained. On this basis, through the structure of the linkage mechanism itself and its matching relationship with the base 4, when the connection part 2 10 is actuated, the bag holding assembly 1 moves vertically relative to the bag opening assembly 2. At this time, the bag opening assembly 2 remains in its original position. Since only the bag holding assembly 1 is actuated, the switching movement between the avoidance position and the bag holding position can be well realized. Furthermore, the base 4 is provided with a first guide portion 11 and a second guide portion 12 which are connected to each other, and the connecting portion 9 cooperates with the first guide portion 11 and the second guide portion 12 for movement respectively; the connecting portion 9 moves along the first guide portion 11 to drive the bag opening component 2 to open and close; when the connecting portion 9 moves to the end of the first guide portion 11, the connecting portion 9 transitions to the second guide portion 12, and moves in a direction which is non-collinear with the opening and closing direction of the bag opening component 2, so that the bag opening component 2 generates a spatial displacement for avoidance. The first guide part 11 and the second guide part 12 are configured as slots opened on the base 4, and the slots are L-shaped. It can be understood that the bag opening assembly 2 includes a bag opening mechanism 1 and a bag opening mechanism 2, so the number of slots is two, which are symmetrically distributed on the base 4 compared to the center line of the base 4. Based on this, the number of connecting parts 1 9 is also two, and any connecting part 1 9 has a wheel body 13 that matches the slot, and both connecting parts 1 9 have the ability to slide with the connecting part 2 10 in the opening and closing direction. In the initial state, the connecting part 1 9 is located at the smooth junction of the first guide part 11 and the second guide part 12. With the output of the first power, the connecting part 1 9 first enters the second guide part 12, and then exits the second guide part 12, and then performs a closing movement along the first guide part 11, and then moves in the opposite direction along the first guide part 11 until it moves to the smooth junction of the first guide part 11 and the second guide part 12 to achieve opening, thereby completing the movement of this process stage.Generally speaking, the connection part 19 is located at the smooth junction of the first guide part 11 and the second guide part 12, and is slightly higher than the axis of the first guide part 11, so as to facilitate the transportation of the packaging bag and avoid motion interference with the packaging bag or the clamping component. In order to ensure the relative motion stability between the bag opening component 2 and the bag holding component 1, a guide rod is also provided between the two.

[0066] In this embodiment, the driving component 3 includes a driving member 14 and a driving member 2 15; the driving member 14 is used for the first power output; the driving member 2 15 is used for the second power output; the driving member 14 includes a power member 16, a power member 2 17, and a power member 3 18, one end of the power member 2 17 is hinged to the power member 16, and the other end is hinged to the power member 3 18, the power member 3 18 is movably connected to the bag opening component 2, and the power member 3 18 is also hinged to the base 4; the power member 16 receives the first power output and moves in a straight line, and transmits the first power output to the power member 3 18 via the power member 2 17, so that the power member 3 18 swings to drive the bag opening component 2 to open and close. The power member 16 and the base 4 slide in cooperation in the vertical direction, the middle part of the power member 3 18 is hinged with the base 4, one end of the power member 3 18 is hinged with the power member 2 17, and the other end is provided with a sliding hole, which cooperates with the wheel body 1 13 through the sliding hole, thereby realizing sliding cooperation with the first guide part 11 and the second guide part 12. The driving member 2 15 slides in cooperation with the base 4 in the vertical direction, thereby realizing the up and down movement of the bag-opening assembly 1, and then realizing the differential movement of the bag-opening assembly 2 and the bag-holding assembly 1 through the incompletely consistent movement mode of the connecting part 1 9 and the connecting part 2 10, so as to achieve the coordinated cooperation between the two and realize the specific use requirements of opening and holding the bag mouth of the packaging bag.

[0067] In the present embodiment, the driving assembly 3 further comprises a driving part 1 and a driving part 2 separated from each other, the driving part 1 and the driving part 2 rotate coaxially, and both are closed-loop guiding driving structures, the driving part 1 and the driving member 14 are movably matched, and the driving part 2 and the driving member 2 15 are movably matched. Specifically, the driving assembly 3 is composed of at least one cam. In the present embodiment, the driving assembly 3 comprises a cam 19 and a cam 20, the cam 19 and the cam 20 are integrated into one body, so as to improve the synchronization of movement, the driving part 1 is configured as the side ring groove of the cam 19, and the driving part 2 is configured as the flange surface of the cam 2 20. Therefore, during the coaxial rotation of the cam 19 and the cam 2 20, the differentiated movement of the connecting part 1 9 and the connecting part 2 10 is realized by relying on the different shapes of the driving part 1 and the driving part 2. The power member 16 has a wheel body 2 matched with the driving part 1, and the driving member 2 15 has a wheel body 3 matched with the driving part 2. Further, as Figure 5 and Figure 6As shown, the first driving part has an opening and holding section 21, a preparation section 22, a closing movement section 23, and an opening movement section that are connected end to end; the opening and holding section 21 is an arc with the rotation axis as the center of the circle; in the direction where the first driving member 14 transitions from the opening and holding section 21 to the closing movement section 23, the distance from the preparation section 22 to the rotation axis first decreases and then increases; in the direction where the first driving member 14 transitions from the preparation section 22 to the opening movement section, the distance from the closing movement section 23 to the rotation axis increases; in the direction where the first driving member 14 transitions from the closing movement section 23 to the opening and holding section 21, the distance from the opening movement section to the rotation axis decreases; the second driving part has a position holding section 27, a displacement section 28, and a position holding section 29 that are connected end to end; both the position holding section 27 and the position holding section 29 are arcs with the rotation axis as the center of the circle, and the diameter of the position holding section 29 is larger than the diameter of the position holding section 27; in the direction where the second driving member 15 transitions from the position holding section 27 to the position holding section 29, the distance from the displacement section 28 to the rotation axis increases. Since the diameter of the position holding section 29 is larger than the diameter of the position holding section 27, the position of the third wheel body in the position holding section 27 is lower than the position of the third wheel body in the position holding section 29. At this time, the bag supporting assembly 1 is in the bag supporting position and is also in the state of receiving the packaging bag. During specific use operations, in the initial stage, the second wheel body is located in the opening and holding section 21, and the third wheel body is located in the position holding section 27, as Figures 5 to 8As shown, the second wheel body enters the preparation section 22. The preparation section 22 is linear and has the characteristic that the distance to the rotation axis first decreases and then increases. Therefore, the first wheel body 13 will first enter the second guiding part 12 to achieve the avoidance of the packaging bag / clamping mechanism. At this time, the clamping assembly has corresponding cooperation and can transfer the packaging bag to between the first bag-opening mechanism and the second bag-opening mechanism well. Then, the first wheel body 13 exits the second guiding part 12, making the first wheel body 13 tend to move along the first guiding part. At this time, the second wheel body has entered the first displacement section 28 from the first position-holding section 27, that is, at this time, the bag-supporting assembly 1 starts to move upward, so that when the bag-opening assembly 2 makes a closing movement, the bag-supporting assembly 1 is located above the bag-opening assembly 2 and does not affect the two suction cups 5 from adsorbing the packaging bag. Then, the second wheel body enters the closing movement section 23, making the bag-opening assembly 2 perform a closing movement, and at the same time, the bag-supporting assembly 1 also performs a closing movement until the suction cups 5 adsorb the packaging bag. During this process, the third wheel body has passed through the first displacement section 28 and is located at the second position-holding section 29. In fact, the opening and holding section 21 includes a gentle opening section 24 and a rapid opening section 25. The connection between the second displacement-holding section and the first displacement-holding section is the second rapid descent part 26. That is to say, the third wheel body enters the first displacement-holding section from the second position-holding section 29 in a rapid descent manner, aiming to make the paddle 6 in the avoidance position quickly enter the packaging bag. Therefore, when the second wheel body enters the gentle opening section 24, the third wheel body transitions from the second position-holding section 29 to the first position-holding section 27 through the second rapid descent part 26. Then, the second wheel body enters the rapid opening section 25 to achieve the rapid opening of the packaging bag. Further, the gentle opening section 24 also includes a first movement section and a second movement section. The first movement section realizes the opening of the packaging bag, and the second movement section maintains the current opened state of the packaging bag and waits for the paddle 6 to extend into the packaging bag. It can be seen that the second movement section is an arc with the rotation axis as the center. Thus, after the paddle 6 enters the packaging bag, the second wheel body enters the rapid opening section 25, thereby realizing the rapid opening of the rapid bag-opening assembly 2 and the bag-supporting assembly 1. During this process, the third wheel body is also located at the first position-holding section 27. When the second wheel body moves in the opening and holding section 21 and the third wheel body moves in the first position-holding section 27 at the same time, the packaging bag can be fed. After the feeding is completed, according to the actions of the first cam 19 and the second cam 20, the bag-supporting assembly 1 first switches to the bag-supporting position and disengages from the packaging bag. At this time, the clamping assembly can remove the packaging bag after feeding.

[0068] Thus, through the cyclic repetition of the above movement process, the complete process actions can be continuously realized.

[0069] As Figure 1 and Figure 2As shown, in this embodiment, the integrated mechanism can also integrate the linkage of the blanking assembly 30. Further, it further includes the blanking assembly 30, and the blanking assembly 30 is movably arranged on the base 4; the driving assembly 3 also branches out a third power output, and the third power output drives the blanking assembly 30 to extend into the packaging bag for blanking when forming a blanking channel. The driving assembly 3 further includes a third driving member 31 for the third power output; a third driving part separated from the first driving part and the second driving part, the third driving part rotates coaxially with the first driving part, the third driving part has a closed-loop guiding and driving structure, and the third driving part is movably matched with the third driving member 31. The third driving member 31 and the base 4 are slidably matched in the vertical direction. In order to further maintain the movement stability, a first guide block 32 is fixedly arranged on the second driving member 15, and a second guide block 33 is arranged on the connecting part 2. The first guide block 32 and the second guide block 33 are respectively sleeved on the outer side of the third driving member 31, so as to respectively realize the sliding fit with the third driving member 31. At the same time, in the vertical direction, a guiding and coupling member can also be arranged between the connecting part 2 and the blanking assembly 30. The driving member has a fourth wheel body for cooperating with the third driving part. In this embodiment, the third driving part is configured as the flange surface of the first cam 19, which can reduce the layout volume of the driving assembly 3 and effectively ensure the structural stiffness of the cam. It can be known that each driving part can be configured by using different cams, or the three driving parts can be configured on one cam, that is, two driving parts are respectively configured as the annular grooves on both sides of the cam, and the other driving part is located as the flange surface of the cam.

[0070] As Figure 6 and Figure 7 As shown, further, the third driving part has a third position maintaining section 34, a second displacement section 35 and a fourth position maintaining section 36 which are connected end to end; both the third position maintaining section 34 and the fourth position maintaining section 36 are arcs with the rotation axis as the center of the circle, and the diameter of the fourth position maintaining section 36 is larger than that of the third position maintaining section 34; in the direction where the third driving member 31 transitions from the fourth position maintaining section 36 to the third position maintaining section 34, the distance from the second displacement section 35 to the rotation axis decreases. In the initial state, when the first wheel body 13 is located in the opening maintaining section 21, the fourth wheel body is located in the third position maintaining section 34. When the fourth wheel body enters the second displacement section 35 and drives the blanking assembly 30 to move upward and during the movement in the third position maintaining section 34, the second wheel body moves on the preparation section 22 and the closing movement section 23 to close. The fourth wheel body continues to move on the third position maintaining section 34, and the second wheel body initially enters the opening movement section. After that, the fourth wheel body moves to the third position maintaining section 34 and starts to move downward. When the second wheel body returns to the position in the initial state, the hopper of the blanking assembly 30 extends well into the packaging bag through the blanking channel and stays, so as to carry out blanking. It can be seen that according to the actions of the first cam 19 and the second cam 20, when the bag supporting assembly 1 moves upward, the blanking assembly 30 also moves upward, so that the clamping assembly can move out of the packaging bag.

[0071] Furthermore, the second displacement section 35 has at least one first rapid drop section 37. The arrangement of the first rapid drop section 37 can achieve the downward jitter of the blanking assembly 30. At this time, the uniformity of the material in the hopper of the blanking assembly 30 can be improved, and at the same time, the blockage of the material can be prevented. While realizing the jitter of the material, the material residue can also be effectively reduced.

[0072] Thus, through this embodiment, the bag opening, bag stretching, and blanking of the packaging bag can be realized by the same power source. There is a high linkage between the bag opening assembly 2, the bag stretching assembly 1, and the blanking assembly 30. The mechanical transmission mechanism is simple and easy to implement, and at the same time, the volume of the packaging machine is well reduced. When any one of the transmission parts between the action mechanism and the power source fails, timely parking can also be achieved.

[0073] As Figure 1 shown, in this embodiment, a holding mechanism is respectively connected to the second wheel body, the third wheel body, and the fourth wheel body to maintain relative vertical movement or substantially vertical movement. The holding mechanism includes a seat body 38 and a swing rod 39. The seat body 38 is fixedly arranged. One end of the swing rod 39 is hinged to the seat body 38, and the other end is connected to the corresponding wheel body. Thus, when the wheel body moves along the corresponding driving part, the swing rod 39 swings to maintain the position of the wheel body, thereby improving the linkage movement stability of the integrated mechanism.

[0074] This embodiment is used for a packaging machine. Therefore, the synchronous blanking of multiple packaging bags should be realized as much as possible. Therefore, the integrated mechanism of this embodiment has multiple process positions, and the arrangement direction of the process positions is perpendicular to the opening and closing direction of the bag opening assembly 2, thereby realizing the synchronous action of multiple work positions.

[0075] The above is only the preferred embodiment of the present invention. It should be noted that the above preferred embodiment should not be regarded as a limitation of the present invention. The protection scope of the present invention should be subject to the scope defined by the claims. For those of ordinary skill in the art of this technology, without departing from the spirit and scope of the present invention, several improvements and retouches can also be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
