DETAILED DESCRIPTION

[0037] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0038] Please refer to Figure 1-11 As shown, an embodiment of the present application provides a packaging machine, including a rotating component 2, a packaging bag carrier 4 and a posture control mechanism 3, wherein the rotating axis of the rotating component 2 is arranged in a transverse direction, and the packaging bag carrier 4 is rotatably connected to the rotating circumference of the rotating component 2.

[0039] The packaging machine is a bagging packaging machine, which realizes the packaging of materials through processes such as bagging, loading and heat sealing. The packaging bag carrier 4 on it is rotatably arranged to carry the packaging bag 0 and drive the packaging to move between different stations with the rotating component 2. The rotating component 2 is used to switch the packaging bag 0 on the packaging bag carrier 4 between different stations by rotating to perform processes such as bag taking, loading and heat sealing, and the rotating axis of the rotating component 2 is set horizontally, which is convenient for multi-station parallel expansion, and can perform packaging processing at multiple stations at the same time, improve packaging processing efficiency, and has a compact structure and occupies little space. The posture control mechanism 3 is used to control the packaging bag carrier 4 to maintain a preset posture between different stations, so as to facilitate the corresponding processes at different stations.

[0040] Please refer to Figure 3-5As shown, in an embodiment of the present application, the path of the packaging bag carrier 4 rotating circumferentially with the rotating component 2 includes a posture maintaining section 23, a posture adjustment section 1 21 and a posture adjustment section 22 which are connected in sequence, a bag loading station 01 is arranged between the posture adjustment section 1 21 and the posture adjustment section 2 22, and a loading station 02 is arranged in the posture maintaining section 23.

[0041] The workstations of the packaging machine are arranged around the circumference of the rotating member 2, and multiple workstations can be arranged according to needs or actual conditions, such as 3-5 workstations. In the embodiment of the present application, the workstations at least include a bagging station 01 and a loading station 02. The bagging station 01 is used to load the bag when the bag carrier 4 moves to the bagging station 01, that is, to load the bag 0 on the bag carrier 4. The loading station 02 is used to load the material into the bag 0, and the bag mouth of the bag 0 needs to be kept in an upward posture during the bagging process. For the convenience of the following description, the bag carrier 4 is named as the first posture in this posture, and the bag carrier 4 is in the second posture with the bag mouth of the bag 0 facing horizontally when in the bagging station 01. In this way, the path of the packaging bag carrier 4 rotating circumferentially with the rotating component 2 can be divided into a posture maintaining section 23, a posture adjustment section 1 21 and a posture adjustment section 22. The packaging bag carrier 4 performs corresponding posture maintaining and posture switching when moving along each path section, so as to facilitate processing at corresponding workstations.

[0042] On this basis, in order to achieve that the packaging bag 0 on the packaging bag carrier 4 can at least maintain a first posture at the loading station 02 and maintain a second posture that is convenient for bag loading at the bag loading station 01, the posture control mechanism 3 controls the posture of the packaging bag carrier 4 during the rotation process. During the movement of the packaging bag carrier 4 along the posture maintaining section 23, the posture control mechanism 3 drives the packaging bag carrier 4 to maintain the first posture with the bag mouth of the packaging bag 0 facing upward, that is, the packaging bag carrier 4 is in the same fixed posture relative to the ground during the movement along the posture maintaining section 23. The packaging bag carrier 4 moves from the posture maintaining section 23 along the posture adjustment section 21. When it reaches the bag loading station 01, the posture control mechanism 3 drives the packaging bag carrier 4 to switch from the first posture to the second posture with the bag opening of the packaging bag 0 facing horizontally, that is, when the packaging bag carrier 4 moves to the bag loading station 01, it rotates relative to the ground and switches to the second posture to receive the packaging bag 0 fed by the bag loading device. When the packaging bag carrier 4 moves from the bag loading station 01 along the posture adjustment section 22 to the posture holding section 23, the posture control mechanism 3 drives the packaging bag carrier 4 to switch from the second posture to the first posture, that is, when the packaging bag carrier 4 moves to the posture holding section 23, it rotates again relative to the ground to return to the first posture.

[0043] Among them, the posture control mechanism 3 is used to control the packaging bag carrier 4 to maintain a preset posture in different path sections for movement. When the packaging bag carrier 4 moves along the posture holding section 23, the posture control mechanism 3 drives the packaging bag carrier 4 to maintain the first posture with the bag opening of the packaging bag 0 facing upward. In this posture, the packaging bag carrier 4 can be loaded with solid or liquid materials from top to bottom, and in this posture, the problems of easy shrinkage and uneven bag opening of the packaging bag 0 when the material is loaded horizontally can be avoided, making loading more convenient, reducing other mechanisms to prevent shrinkage and uneven bag opening, and reducing costs. When the packaging bag carrier 4 moves from the posture holding section 23 to the bag loading station 01, the posture control mechanism 3 drives the packaging bag carrier 4 to switch from the first posture to the second posture with the bag opening of the packaging bag 0 facing horizontally. In the second posture, the packaging bag carrier 4 can be easily loaded on the bag loading station 01 through the bag loading mechanism 5 on the station. Since the rotating component 2 drives the packaging bag carrier 4 to rotate and switch between multiple workstations, when the packaging bag carrier 4 moves from the bag loading station 01 along the posture adjustment section 22 to the posture maintaining section 23, the posture control mechanism 3 needs to switch the packaging bag carrier 4 from the second posture back to the first posture, so that loading can be carried out from top to bottom.

[0044] It can be understood that the posture control mechanism 3 mainly drives the packaging bag carrier 4 connected to the rotating component 2 to rotate relative to the rotating component 2 to switch the posture. The posture control mechanism 3 can be a motor-based power mechanism, which is arranged on the rotating component 2. The power mechanism is connected to the packaging bag carrier 4 in transmission. The power mechanism can adjust the posture of the packaging bag carrier 4 by adjusting the rotation rate and rotation direction, or it can be achieved through some guiding mechanisms to switch and maintain the corresponding posture, or it can be achieved by other existing mechanisms that play the same role, without limitation.

[0045] Through the above technical solution, the posture control mechanism 3 controls the posture of the packaging bag carrier 4 on the rotating member 2, which can not only make the packaging bag 0 on the packaging bag carrier 4 switch to a preset posture or maintain a preset posture between different stations, but also can greatly reduce the length of the packaging bag 0 on the plane during the packaging process by setting the processing station on the circumference of the rotating member 2, thereby significantly reducing the overall volume of the packaging machine and improving the work efficiency. Moreover, by setting a plurality of stations including the bag loading station 01 and the loading station 02 on the rotating circumference of the rotating member 2, the posture control mechanism 3 can be used to realize horizontal bag loading, and when moving toward the loading station 02, the packaging bag 0 can be switched to a posture with the bag mouth facing upward and maintained in this posture, which can be more conducive to loading, and can also avoid the problems of shrinkage and uneven bag mouth when the bag mouth is facing horizontally, and the material falling out of the packaging bag 0, and when moving to the bag loading station 01, it can be flipped to a horizontal state, so that cyclic state switching and continuous packaging can be realized, and the work efficiency is improved.

[0046] In one embodiment, in combination Figure 3-7 As shown, the posture control mechanism 3 may include a guide member 33 connected to the packaging bag carrier 4, and the guide member 33 moves along the guide path 31 of the annular structure with the rotation of the rotating component 2. The guide member 33 is eccentrically arranged relative to the hinge point between the packaging bag carrier 4 and the rotating component 2, and the guide member 33 moves along the guide path 31 to control the posture of the packaging bag carrier 4 during the rotation of the packaging bag carrier 4 with the rotating component 2; the guide path 31 includes a guide segment 1 313 corresponding to the posture adjustment segment 1 21, a guide segment 2 314 corresponding to the posture adjustment segment 22, and a guide segment 3 315 corresponding to the posture maintaining segment 23, which are connected in sequence.

[0047] In this manner, the posture control mechanism 3 adopts a guiding structure to realize the posture switching and posture maintenance of the packaging bag carrier 4. It moves along a preset annular structure guiding path 31 through a guide member 33 connected to the packaging bag carrier 4 as the rotating component 2 rotates. Since the guide member 33 is eccentrically arranged relative to the hinge point between the packaging bag carrier 4 and the rotating component 2, the actuator can be rotated around the hinge point between the packaging bag carrier 4 and the rotating component 2 through the preset guiding path 31, thereby driving the packaging bag carrier 4 to rotate to the corresponding posture or maintain the posture. In this way, the guide path 31 may include a guide segment 1 313 corresponding to the posture adjustment segment 1 21, a guide segment 2 314 corresponding to the posture adjustment segment 22, and a guide segment 3 315 corresponding to the posture maintaining segment 23, which are connected in sequence. When the guide member 33 moves along the guide segment 1 313, the posture can be adjusted from the first posture to the second posture; when the guide member 33 moves along the guide segment 2 314, the posture can be adjusted from the second posture to the first posture; when the guide member 33 moves along the guide segment 3 315, the posture can be maintained and move in the first posture, thereby realizing the posture switching and maintenance of the packaging bag carrier 4 through guidance.

[0048] Furthermore, the guide section three 315 is in an arc shape, and its radius is the same as the rotation radius of the hinge point between the packaging bag carrier 4 and the rotating member 2. The center of the guide section three 315 is eccentric with respect to the rotation axis of the rotating member 2, and the "distance from the center of the guide section three 315 to the rotation axis of the rotating member 2" is consistent with the "distance from the guide member 33 to the hinge point between the packaging bag carrier 4 and the rotating member 2"; the guide section one 313 is in an arc shape, and the center of the guide section one 313 coincides with the rotation axis of the rotating member 2; the guide section two 314 is an arc with a gradually changing radius of curvature connected between the guide section one 313 and the guide section three 315.

[0049] Since the guide member 33 is eccentrically arranged relative to the hinge point between the packaging bag carrier 4 and the rotating member 2, when the rotating member 2 rotates along its rotation axis, in order to achieve that the relative orientation of the guide member 33 relative to the hinge point remains unchanged so as to maintain the first posture, a circular arc-shaped guide section three 315 is provided and its radius is configured to be the same as the rotation radius of the hinge point between the packaging bag carrier 4 and the rotating member 2, and its center is also eccentric to the rotation axis of the rotating member 2, so that the guide member 33 can maintain the posture of the packaging bag carrier 4 when rotating with the rotating member 2. In the process of moving along the guide section three 315, the packaging bag carrier 4 revolves with the rotating member 2 while also rotating relative to the rotating member 2, and at the same time, the packaging bag carrier 4 does not rotate relative to the ground but remains in the first posture, thereby facilitating loading from top to bottom; the guide section one 313 is configured as an arc shape and its center coincides with the rotation axis of the rotating member 2, and its center coincides with the rotation axis of the rotating member 2. The rotation circumference of the point is concentric, that is, the guide member 33 and the hinge point move on circles with the same center but different radii, so that during the rotation of the rotating member 2, the packaging bag carrier 4 only revolves with the rotating member 2 and does not rotate relative to the rotating member 2, that is, the packaging bag carrier 4 will rotate relative to the ground, so that the packaging bag carrier 4 can be rotated from the first posture to the second posture facing horizontally; and the guide section 2 314 is configured as an arc with a gradually changing radius of curvature, so that the packaging bag carrier 4 can be guided in the opposite direction during the rotation of the guide member 33 with the rotating member 2, so that the packaging bag carrier 4 revolves with the rotating member 2 and rotates relative to the rotating member 2 at the same time, and at the same time, the packaging bag carrier 4 is switched from the second posture to the first posture relative to the ground. For example, when the rotating member 2 rotates clockwise, the cooperation of the guide section 2 314 and the guide member 33 is used to drive the packaging bag carrier 4 to rotate counterclockwise relative to the rotating member 2, thereby realizing the adjustment of the packaging bag carrier 4 from the second posture to the first posture.

[0050] In some specific embodiments, the guide member 33 may be a guide portion moving along a guide path, or the guide member 33 may include multiple guide portions, each of which moves along a guide line. Both methods can achieve posture maintenance and adjustment of the packaging bag carrier 4.

[0051] Since the guide path 31 uses a guide structure such as a cam groove for guidance, there is often a large pressure angle during the guiding contact process. The large pressure may cause the guide member 33 to get stuck during the rotation of the rotating component 2, resulting in an unsmooth guiding process.

[0052] In order to solve this problem, in a preferred technical solution, the guide member 33 includes a guide portion 1 331 and a guide portion 2 332, and the guide path 31 includes a guide line 1 311 coordinated with the guide portion 1 331 and a guide line 2 312 coordinated with the guide portion 2 332; the guide segment 2 314 of the guide line 1 311 and the guide segment 2 314 of the guide line 2 312 have different curvature radius changes.

[0053] The guide member 33 is provided with two guide parts, namely the guide part 1 331 and the guide part 2 332. The guide part 1 331 and the guide part 2 332 move along a guide path 31 respectively. For the convenience of distinction, the guide path 31 coordinated with the guide part 1 331 is the guide line 1 311, and the guide path 31 coordinated with the guide part 2 332 is the guide path 312. In this way, the pressure generated in the guiding process can be dispersed by the guide part 1 331 and the guide part 2 332, and the friction of the guide member 33 in the guiding process can be reduced, so that the guiding process is smoother and more stable; in the guide section 2 314 of the guide line 1 311 and the guide line 2 312, by setting the curvature changes of the two to be different, the guide part 1 331 and the guide part 2 332 can be better adjusted in posture when moving along the guide section 2 314, that is, the second horizontal posture is adjusted to the first vertical posture with the bag opening facing upward.

[0054] In a specific implementation process, the distance from the guide part 1 331 to the hinge point between the packaging bag carrier 4 and the rotating member 2 is the same as the distance from the guide part 2 332 to the hinge point between the packaging bag carrier 4 and the rotating member 2, and the guide section 1 313 of the guide line 1 311 and the guide section 1 313 of the guide line 2 312 have a path overlap section. By configuring the distances between the guide part 1 331 and the guide part 2 332 and the hinge point between the packaging bag carrier 4 and the rotating member 2 to be the same, the guide part 1 331 and the guide part 2 332 can have a path overlap section when traveling along the guide section 1 313, that is, a section of the path of the two overlaps, and although there is a path overlap section, the guide part 1 331 and the guide part 2 332 still travel along their respective guide lines in an orderly manner.

[0055] The posture control mechanism 3 specifically includes a guide plate 32 which is stationarily arranged parallel to the rotating member 2, and the guide plate 32 is provided with an annular cam groove 321 which constructs the guide path 31, the guide portion 1 331 is fitted in the annular cam groove 321 of the guide line 1 311, and the guide portion 2 332 is fitted in the annular cam groove 321 of the guide line 2 312, and there is a height difference between the groove depths of the annular cam groove 321 of the guide line 1 311 and the annular cam groove 321 of the guide line 2 312.

[0056] By constructing the annular cam groove 321 structure of the guide path 31, when the guide part 1 331 and the guide part 2 332 move along the annular cam groove 321 of their respective guide lines, since there is an intersection between the guide line 1 311 and the guide line 2 312, by configuring the groove depths of the annular cam groove 321 of the guide line 1 311 and the annular cam groove 321 of the guide line 2 312 to have a height difference, it is convenient for the guide part 1 331 and the guide part 2 332 to move along their respective guide lines in an orderly manner, avoiding the situation where the guide part 1 331 or the guide part 2 332 is misplaced and enters an incorrect guide line during the moving process, thereby ensuring the reliability of the entire posture adjustment process.

[0057] To better illustrate the movement process of the guide part 1 331 and the guide part 2 332, please refer to Figure 4-Figure 7As shown, the guide path 31 of the guide part 1 331 is the guide line 1 311, and the guide path 31 of the guide part 2 332 is the guide line 2 312. The guide line 1 311 and the guide line 2 312 have a path overlap section in the guide section 1 313. When the packaging bag carrier 4 moves from the posture maintaining section 23 to the posture adjusting section 2 22 along with the rotating member 2, the guide part 1 331 and the guide part 2 332 gradually transition from the guide section 3 315 of the guide line 1 311 and the guide section 3 315 of the guide line 2 312 to the path overlap section of the guide section 2 314, respectively. In this process, the guide part 1 331 and the guide part 2 332 gradually transition from the guide section 3 315 of the guide line 1 311 and the guide section 3 315 of the guide line 2 312 to the path overlap section of the guide section 2 314. The orientation relationship between the second 332 and the hinge point of the rotating component 2 and the packaging bag carrier 4 will change relatively, and the packaging bag carrier 4 will be gradually turned over and adjusted from the first posture with the bag mouth facing upward; when the packaging bag carrier 4 moves to the bagging station 01, the guide part 1 331 and the guide part 2 332 of the guide member 33 are guided by the guide section 1 313, and the packaging bag carrier 4 is turned 90 degrees from the first posture to the second posture facing horizontally, and the bagging mechanism 5 on the bagging station can bag it in this posture; after the packaging bag carrier 4 is bagged at the bagging station 01, the bag mouth of the packaging bag 0 on the packaging bag carrier 4 faces horizontally, and the guide section 1 313 is guided by the guide section 1 313. The first guide portion 331 enters the second guide segment 314 of the first guide line 311, and the second guide portion 332 enters the second guide segment 314 of the second guide line 312. Since the curvature radius of the second guide segment 314 of the two lines varies differently, during the process of the guide member 33 rotating with the rotating member 2, the first guide portion 331 and the second guide portion 332 are respectively guided by the corresponding second guide segment 314, so that the packaging bag carrier 4 can rotate relative to the rotating member 2 in the direction opposite to the rotation direction of the rotating member 2, thereby adjusting the posture of the packaging bag carrier 4 from the second posture to the first posture. When the first guide portion 331 and the second guide portion 332 are respectively When it moves to the end of the corresponding guide section 2 314 in succession, the posture adjustment of the packaging bag carrier 4 is completed. Under the rotation drive of the rotating component 2, the guide part 1 331 and the guide part 2 332 will enter the guide section 3 315 of their respective guide lines. At this time, the packaging bag carrier 4 is in the first posture and will maintain the first posture in the posture maintaining section 23, and then can be moved to the loading station 02 for loading from top to bottom, and then the rotating component 2 continues to rotate to drive the packaging bag carrier 4 to move to the guide section 1 313 again, thereby completing a packaging process of material packaging, and through reciprocating cycles, more efficient material packaging can be achieved.

[0058] In this embodiment, the power mechanism is arranged on the rotating member 2 and rotates circumferentially with the rotating member 2. During the rotation of the rotating member 2, the power mechanism can drive the packaging bag carrier 4 to rotate in the opposite direction and control it at a suitable rotation rate, and can also realize the packaging bag carrier 4 to maintain the packaging bag 0 in the work station with the bag opening facing upward and switch the posture. Specifically, the power structure can be a driving motor, which drives the packaging bag carrier 4 to rotate.

[0059] Please refer to Figure 1 , Figure 5 and Fig. 9 As shown, in the embodiment of the present application, the packaging machine is capable of heat sealing, and the heat sealing can be performed by setting a heat sealing mechanism 7 in the posture holding section 23, or by an external heat sealing mechanism 7, without limitation.

[0060] On this basis, in one embodiment, a heat sealing station 03 is further provided on the posture holding section 23, and the heat sealing station 03 is provided with a heat sealing mechanism 7 for heat sealing the packaging bag 0 after unloading, and the heat sealing mechanism 7 includes a fixed heat sealing part 74, a movable heat sealing part 72 and a driving device 71, and the driving device 71 drives the movable heat sealing part 72 to flip and clamp relative to the fixed heat sealing part 74 between the avoidance position and the working position.

[0061] In this embodiment, the heat sealing station 03 is arranged in the posture holding section 23, and the heat sealing mechanism 7 on the heat sealing station 03 heat seals the packaging bag 0 on the packaging bag carrier 4 in the first posture. Since the bag mouth of the packaging bag 0 faces upward, the heat sealing of the bag mouth of the packaging bag 0 can be achieved by flipping the heat sealing method. Specifically, the heat sealing mechanism 7 mainly consists of a fixed heat sealing part 74, a movable heat sealing part 72 and a driving device 71. The fixed heat sealing part 74 is fixedly arranged at the heat sealing station 03 and is located on one side of the bag mouth of the packaging bag 0. The driving device 71 is connected to the movable heat sealing part 72 and is used to drive the movable heat sealing part 72 to switch between the working position and the avoidance position. When the movable heat sealing part 72 is in the avoidance position, it is located above the fixed heat sealing position, and when in the working position, it flips to the opposite side of the fixed heat sealing position and clamps the bag mouth of the packaging bag 0, so that the bag mouth can be fused at high temperature to achieve heat sealing of the bag mouth. The movable heat sealing portion 72 is an L-shaped structure, a heat sealing block 73 is arranged inside the movable heat sealing portion 72 , and the fixed heat sealing portion 74 is also fixedly arranged on the heat sealing block 73 .

[0062] In another embodiment, a transfer station (not shown in the figure) may be provided on the posture holding section 23, and the transfer station is provided with a transfer mechanism to transfer the filled packaging bag 0 to a vacuum pumping mechanism (not shown in the figure).

[0063] In this embodiment, the set transfer station can facilitate the setting of the transfer mechanism, and the packaging bag 0 after filling can be clamped and moved to the vacuum mechanism through the transfer mechanism. The vacuum mechanism can form a vacuum environment inside or outside the packaging bag 0, and heat sealing is performed under the vacuum environment. Under this environment, the air in the packaging bag 0 is discharged in large quantities, reducing the content of gases such as oxygen, which can effectively inhibit the growth of aerobic microorganisms and oxidation reactions of products.

[0064] In order to facilitate the packaging bag 0 to be shipped after heat sealing, combined with Figure 2 and Figure 5 As shown, a delivery station 04 is provided on the posture adjustment section 1 21 or the posture holding section 23, and the delivery station 04 is provided with a packaging bag conveying mechanism 9. By providing the delivery station 04 on the posture adjustment section 1 21 or the posture holding section 23, the packaging bag 0 can be conveyed and shipped through the packaging bag conveying mechanism 9 on the station after being loaded or heat-sealed. Specifically, the packaging bag conveying mechanism 9 can be conveyed by a conveyor belt, for example, the conveyor belt mechanism is provided below the heat-sealing mechanism 7, and the packaging bag 0 can fall onto the conveyor belt mechanism after being heat-sealed and be transported and shipped out.

[0065] Please refer to Figure 1 and Figure 8 As shown, in an embodiment of the present application, the bag loading station 01 is provided with a bag loading mechanism 5 , and the bag loading mechanism 5 transports the packaging bag 0 with the bag opening facing horizontally in a transverse direction to the packaging bag carrier 4 at the bag loading station 01 .

[0066] The bag loading mechanism 5 provided at the bag loading station 01 is a transverse bag loading method, which loads the packaging bag 0 transversely on the packaging bag carrier 4 in the transversely oriented second posture. Specifically, the bag loading mechanism 5 may include a bag bin 51 for stacking the packaging bags 0 and a transverse transfer mechanism 52 such as a screw nut pair. The transverse transfer mechanism may move transversely and take out the packaging bag 0 from the bottom of the bag bin 51 through a vacuum suction cup 53, and then move transversely to transfer it to the packaging bag carrier 4 with a clamping port. The packaging bag carrier 4 may load the packaging bag 0 by clamping.

[0067] Please refer to Fig.11 As shown, in an embodiment of the present application, the packaging bag carrier 4 includes a bag clamping assembly, which includes two clamping parts 42 and a transmission shaft 43 that is transmission-connected to the two clamping parts 42 for clamping action, and the transmission shaft 43 is connected to a gear 41; a driving device 28 is provided at the bag loading station 01, and the driving device 28 includes a driving motor 1 82 and an incomplete gear 81 driven by the driving motor 1 82, and the incomplete gear 81 is partially meshed with the gear 1 41, and the driving motor 1 82 drives the incomplete gear 81 to switch between the avoidance position and the transmission position in the circumferential direction.

[0068] The packaging bag carrier 4 mainly includes a bag clamping assembly, through which the packaging bag 0 is clamped. The two clamping parts 42 of the bag clamping assembly are clamped through the transmission shaft 43, and the transmission shaft 43 is connected to a gear 1 41, and the gear 1 41 is used to mesh with the incomplete gear 81 of the driving device 2 8. Since the transmission member of the driving device 2 8 is an incomplete gear 81, the incomplete gear 81 can be circumferentially switched between the transmission position and the avoidance position by rotation, that is, when the tooth portion of the incomplete gear 81 rotates to the transmission position, it can mesh with the gear 1 41, and the driving of the clamping assembly can be realized by rotation, and when the tooth portion of the incomplete gear 81 rotates to the other side, the area where the tooth portion is not set does not mesh with the gear 1 41, and thus does not cause interference or transmission to the gear 1 41, thereby realizing selective avoidance and transmission. In this way, the driving device 2 8 can be arranged outside the rotating member 2 or the packaging bag carrier 4, which can reduce the weight and structural complexity of the bag clamping assembly. Specifically, a cam member 44 is provided on the transmission shaft 43, and a pressure rod 45 rotatably arranged on the bag clamping assembly mounting frame is abutted on the cam member 44, and the other end of the pressure rod 45 is connected to two clamping parts 42 whose movable direction is consistent with the movable direction of the pressure rod 45, and the other clamping part 42 is fixedly arranged, and the interactive clamping part 42 is provided with a spring 47, so that when the transmission shaft 43 rotates to lift the pressure rod 45, the other end of the pressure rod 45 will drive the movable clamping part 42 to move relative to the other clamping part 42, and then an opening action can be performed to clamp the packaging bag 0; at the same time, multiple groups of bag clamping assemblies can realize the bag opening action through relative movement along the axial direction, for example, two movable shafts 46 are respectively connected to a bag clamping assembly and drive the two groups of bag clamping assemblies to move relative to each other, thereby realizing the bag opening action.

[0069] In order to facilitate the loading of materials into the packaging bag 0 with the bag opening facing upward, Figure 1 and Fig.10 As shown, further, a loading station 02 is provided on the rotating circumference of the rotating component 2, and the loading station 02 is provided with a unloading mechanism 6. The unloading mechanism 6 includes a material pump 61 and a vertically arranged discharge pipe 62 connected to the material pump 61, and bag opening components 63 are provided on both sides below the discharge pipe 62.

[0070] In this way, through the unloading mechanism 6 on the unloading station, when the packaging bag carrier 4 moves to the unloading station, the unloading mechanism 6 can be vertically aligned with the packaging bag 0, and the material can be dropped into the packaging bag 0 through the discharge of the unloading mechanism 6, so as to realize the loading. In the specific implementation process, the material can be a fixed material or a liquid material, and there is no restriction. The unloading mechanism 6 is preferably a unloading mechanism 6 for liquid material loading, for example, the unloading mechanism 6 includes a material pump 61 and a discharge pipe 62 connected to the material pump 61, and the discharge pipe 62 is vertically arranged and located directly above the packaging bag carrier 4 when it is in the loading station 02. When there is a packaging bag 0 below, the material pump 61 starts to control the material to be discharged from the discharge pipe 62 into the packaging bag 0. At the same time, a bag opening component 63 such as a vacuum suction cup can be arranged on both sides below the discharge pipe 62, and the bag opening components 63 on both sides can make the two sides of the bag opening be adsorbed so that the bag opening is better opened, and then the material can be better loaded.

[0071] In order to realize batch material packaging, in an embodiment of the present application, the packaging bag carrier 4 includes a plurality of groups of bag clamping assemblies distributed along a first direction parallel to the axial direction of the rotating member 2, the bag loading station 01 is provided with bag loading mechanisms 5 which are the same in number and one-to-one correspond to the bag clamping assemblies, and the loading station 02 is provided with loading mechanisms which are the same in number and one-to-one correspond to the bag clamping assemblies.

[0072] There are multiple groups of bag clamping components distributed along the first direction, and there are also multiple groups of mechanisms on the bag loading station 01 and the loading station 02. In this way, the batch packaging bags 0 can be packaged after the rotating member 2 rotates one circle, which can greatly improve work efficiency.

[0073] Specific, combined Figure 1 and Figure 2 As shown, the rotating member 2 is rotatably arranged on the frame 1, and its rotation is driven by a driving mechanism 1. The main rotating shaft of the driving mechanism 1 connects the two rotating members 2. A plurality of groups of packaging bag carriers 4 distributed along the rotation circumference are arranged between the two rotating members 2, and the mechanism corresponding to each workstation is arranged on the frame 1 along the rotation circumference of the rotating member 2.

[0074] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention, and the protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
