Description

Technical Field

[0001] The utility model relates to the technical field of powder-liquid double-chamber bag manufacturing machinery, and more specifically, to a conveying clamp for a powder-liquid double-chamber bag powder dispensing machine. Background Art

[0002] Powder-liquid double chamber bag powder filling machine is used to produce powder-liquid double chamber bags. Powder-liquid double chamber bag is a kind of ready-to-mix infusion preparation system for intravenous drip, which encapsulates drug powder and injection solvent separately in two chambers of the same packaging bag separated by a virtual weld.

[0003] During the manufacturing process of powder-liquid dual-chamber bags, the powder-liquid dual-chamber bag powder filling machine uses the conveying clamps to transport the packaging bags to the corresponding workstations of each process to cooperate with the operation of other devices. For example, the sterilized packaging bags enter the sterile area for bag opening, packaging, inflation and other processes. However, the existing conveying clamps only have the function of fixing the packaging bags. After the packaging bags are transported to the sterile area, they need to cooperate with the external bag opening suction cup to open and close the packaging bags. Since the bag opening suction cup requires a certain stroke to complete the bag opening and closing action, the bag opening and closing efficiency is low, which in turn affects production efficiency. In addition, the opening and closing of the packaging bags is completely dependent on the suction force of the bag opening suction cup. If the suction force of the bag opening suction cup is insufficient, the opening and closing of the packaging bags will be unstable.

[0004] In summary, how to enable the conveying clamp to control the opening and closing of the bag mouth and cooperate with the suction of the external bag opening suction cup to improve the opening and closing efficiency and stability of the bag is a problem that needs to be solved urgently by technical personnel in this field. Utility Model Content

[0016] Preferably, a pair of detachable positioning columns are provided on the second side of the slider and are located between the pair of bag hanging plates. When the pair of bag hanging plates are both in the initial positions, the pair of positioning columns are in contact with the pair of bag hanging plates accordingly.

[0017] Preferably, it further comprises a pair of clamping assemblies, which are respectively arranged on the top of a pair of bag hanging plates, and the clamping assemblies include:

[0018] A fixing clip is flippably mounted on the bag hanging plate, and the fixing clip is provided with a through hole for the positioning member to pass through;

[0019] A push-pull mechanism is connected to the fixing clip and is used to drive the fixing clip to rotate so as to engage with or disengage from the positioning piece.

[0020] Preferably, the push-pull mechanism includes a cavity, a push rod and a hinged rod. The cavity is provided on the side of the bag hanging plate facing away from the fixed clamp and extends along the axial direction parallel to the positioning member. The push rod is slidably provided inside the cavity along the length direction of the cavity. The hinged rod is provided inside the cavity, and one end of the hinged rod is hinged to the push rod, and the other end passes through the bag hanging plate and is hinged to the fixed clamp.

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] The core of the utility model is to provide a conveying clamp for a powder-liquid dual-chamber bag powder filling machine, which can control the opening and closing of the bag mouth of the packaging bag and cooperate with the suction force of the external bag opening suction cup, thereby greatly improving the opening and closing efficiency and stability of the packaging bag.

[0049] It should be noted that in this embodiment, the orientations or positional relationships indicated by “up”, “down”, “front”, “back”, etc. are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.

[0050] Please refer to Figure 1 and Figure 2 In a specific embodiment, the conveying clamp for the powder-liquid dual-chamber bag powder filling machine provided in the present application includes a slider 1, a pair of bag hanging plates 2, a pair of positioning members 4, a first elastic member 5 and a guide leg 6.

[0051] The first side of the slider 1 is used for being mounted on the timing belt 13 .

[0052] A pair of bag hanging plates 2 are rotatably disposed on the second side of the slider 1 . The pair of bag hanging plates 2 are spaced apart from each other from back to front along the conveying direction of the synchronous belt 13 , and their opposite sides are transmission-connected via a gear meshing structure 3 .

[0053] A pair of positioning members 4 are respectively provided on the top of a pair of bag hanging plates 2 for positioning and installing the packaging bags.

[0054] Both ends of the first elastic member 5 are connected to a pair of bag hanging plates 2 respectively.

[0055] One end of the guide leg 6 is arranged at the bottom of the rear bag hanging plate 2, and the other end of the guide leg 6 is inclined upward toward the direction away from the front bag hanging plate 2, and is used to be slidably arranged on the liftable support mechanism.

[0056] It should be noted that the powder-liquid dual-chamber bag powder filling machine has a conveying system, which is generally composed of a synchronous belt 13, a servo motor for driving the synchronous belt 13 through each process station, a conveying fixture, and a support mechanism. The conveying fixture is connected to the synchronous belt 13, and the support mechanism is installed at the filling station. After the conveying fixture moves to the filling station with the synchronous belt 13, the support mechanism can drive the conveying fixture to rise, so that the bag opening of the packaging bag fixed on the conveying fixture moves to the bag opening suction cup installed on the filling station. The bag opening suction cup opens the bag opening of the packaging bag, and then the filling device installed at the filling station fills the powder chamber of the packaging bag with medicinal powder. Among them, the specific structure and installation method of the synchronous belt 13, the servo motor, the support mechanism, and the bag opening suction cup are not the focus of improvement of this application. Reference can be made to the existing technology and will not be described in detail herein.

[0057] In the above embodiment, the first side of the slider 1 is installed on the synchronous belt 13, so that the overall conveying fixture moves to the subpackaging station with the synchronous belt 13. A pair of bag hanging plates 2 are provided on the other side of the slider 1. The pair of bag hanging plates 2 are arranged from back to front along the conveying direction of the synchronous belt 13, and are divided into a rear bag hanging plate 2b and a front bag hanging plate 2a. The front bag hanging plate 2a and the rear bag hanging plate 2b are both rotatably connected to the other side of the slider 1 through the rotating shaft 8, so that the pair of bag hanging plates 2 can rotate around their corresponding rotating shaft 8.

[0058] In addition, the opposite sides of a pair of bag hanging plates 2 are connected by a gear meshing structure 3, so that the rotation of any bag hanging plate 2 will drive the other bag hanging plate 2 to rotate in the opposite direction. Figure 1 As shown, for example, the top of the rear bag hanging plate 2b is driven to rotate downward toward the front bag hanging plate 2a, and the bottom is driven to rotate upward away from the front bag hanging plate 2a. Even if the rear bag hanging plate 2b rotates counterclockwise, under the power transmission action of the tooth meshing structure 3, the top of the front bag hanging plate 2a will rotate downward toward the rear bag hanging plate 2b, and the bottom will rotate upward away from the rear bag hanging plate 2b, even if the front bag hanging plate 2a rotates clockwise. It can be seen that, by simply driving the bottom of any bag hanging plate 2 to rotate upward away from the other bag hanging plate 2, the tops of a pair of bag hanging plates 2 can be brought closer to each other, and vice versa.

[0059] It is understood that the packaging bag has hanging holes at both corners of the bag opening. A pair of corresponding hanging holes are mounted on a pair of positioning members 4 located at the top of a pair of hanging plates 2, allowing the packaging bag to be mounted between the tops of the pair of hanging plates 2. Therefore, by controlling the relative movement of the pair of hanging plates 2, such that the tops of the pair of hanging plates 2 move toward or away from each other, the opening and closing of the packaging bag can be controlled. It should be noted that the specific structure of the positioning members 4 is not limited and can be conventional hanging pins or other structures, as long as they can be hooked into the hanging holes of the packaging bag.

[0060] Regarding the method of driving the pair of bag hanging plates 2 to move relative to each other, the guide leg 6 structure is adopted in the above embodiment. For details, please refer to Figure 1 The top end of the guide leg 6 is fixed to the bottom of the rear bag hanging plate 2b, and the bottom end is tilted upward, away from the front bag hanging plate 2a, and is placed on a liftable support mechanism. Therefore, on the one hand, the horizontal arrangement direction from the top end to the bottom end of the guide leg 6 is aligned with the conveying direction of the synchronous belt 13, which facilitates the conveying fixture to pull the guide leg 6 forward and reduces the forward resistance of the guide leg 6. On the other hand, the bottom end of the guide leg 6 is tilted upward and placed on the liftable support mechanism. The support mechanism only needs to rise to lift the guide leg 6, which ensures that the bottom of the rear bag hanging plate 2b rotates upward with its back facing the front bag hanging plate 2a, thereby causing the tops of the pair of bag hanging plates 2 to move closer together, driving the bag opening.

[0061] Preferably, please refer to Figure 1 A pulley 7 is set at the other end, i.e. the bottom end, of the guide leg 6, so that the bottom end of the guide leg 6 is slidably placed on the support mechanism, reducing the resistance between the guide leg 6 and the support mechanism, and ensuring the smooth and stable rotation of the rear bag hanging plate 2b.

[0062] It is understood that if the support mechanism descends, the rear bag hanging plate 2b and its guide legs 6 at the bottom will rotate and return to their original positions under their own weight, simultaneously driving the front bag hanging plate 2a to rotate and return to their original positions. If a first elastic member 5 is provided between the pair of bag hanging plates 2, combined with the resilience of the first elastic member 5, the pair of bag hanging plates 2 can be quickly and accurately returned to their original positions.

[0063] To sum up, when the conveying fixture for the powder-liquid double-chamber bag powder filling machine of the above embodiment is used, after a pair of bag hanging plates 2 moves to the filling station with the synchronous belt 13, the support mechanism rises and pushes up the guide leg 6, and the tops of the front bag hanging plate 2a and the rear bag hanging plate 2b move closer to each other, driving the two corners of the bag opening of the packaging bag to fold inward, and then driving the two side sealing edges of the bag opening away from each other, the bag opening of the packaging bag opens, and at the same time, the external bag opening suction cups placed on both sides of the packaging bag respectively absorb the two side sealing edges, which can quickly and stably open the bag opening of the packaging bag. After completing the loading and inflation processes, the suction of the bag opening suction cup is removed and the support mechanism is lowered and reset. With the help of the rebound force of the first elastic member 5, the front bag hanging plate 2a and the rear bag hanging plate 2b are rotated and reset respectively, which can quickly and stably close the bag opening of the packaging bag.

[0064] Therefore, compared with the existing transmission clamp that cannot realize the opening and closing of the packaging bag, the transmission clamp provided by the utility model can realize the opening and closing of the packaging bag by controlling the relative movement of a pair of bag hanging plates 2, and cooperate with the external bag opening suction cup to suck the sealing edges on both sides of the packaging bag, thereby opening and closing the bag mouth of the packaging bag more quickly and stably, thereby improving the production efficiency and yield of the powder-liquid double-chamber bag.

[0065] To prevent the packaging bag from falling off, please refer to the above examples. Figure 1 A pair of positioning members 4 are symmetrically arranged along the conveying direction of the synchronous belt 13, so that the two corners of the packaging bag installed on the pair of positioning members are at the same height, thereby ensuring that the packaging bag is placed more stably on the pair of positioning members to prevent the packaging bag from falling off.

[0066] Regarding the specific implementation of the rotating shaft 8 of a pair of bag hanging plates 2, based on the above embodiment, please refer to Figure 1 The rotating shafts 8 of the pair of bag hanging plates 2 are parallel to each other and located at the same height. This ensures that the pair of bag hanging plates 2 rotate symmetrically without misalignment, thereby preventing the packaging bags installed between the tops of the pair of bag hanging plates 2 from falling off and facilitating smooth control of the opening and closing of the packaging bags.

[0067] Further, in this embodiment, please refer to Figure 1 A pair of positioning members 4, a pair of rotating shafts 8 and a first elastic member 5 are arranged in sequence from top to bottom.

[0068] Since the front and rear bag hanging plates 2b rotate about their respective rotation axes 8, the pair of rotation axes 8 can divide the top and bottom of the front and rear bag hanging plates 2b into two parts with opposite movement trends. A pair of positioning members 4 are respectively provided at the top of the front and rear bag hanging plates 2b. When the tops of the front and rear bag hanging plates 2b move toward each other, the bag opening of the packaging bag is opened, while the bottoms of the front and rear bag hanging plates 2b move away from each other. A first elastic member 5 is located between the bottoms of the front and rear bag hanging plates 2b. The first elastic member 5 can be stretched to store sufficient energy. When the bag opening of the packaging bag needs to be closed, the first elastic member 5 can release the energy to drive the bottoms of the front and rear bag hanging plates 2b to quickly move toward each other, while driving the tops of the front and rear bag hanging plates 2b to move away from each other, so that the front and rear bag hanging plates 2b quickly return to their initial positions. Therefore, the above-mentioned structure is adopted to arrange the positioning member 4, the rotating shaft 8 and the first elastic member 5. On the one hand, the rotating shaft 8 separates the positioning member 4 and the first elastic member 5, avoiding the first elastic member 5 from interfering with the opening and closing of the packaging bag. On the other hand, the first elastic member 5 is placed between the bottoms of a pair of bag hanging plates 2, which is conducive to the rapid closing of the pair of bag hanging plates 2. At this time, the first elastic member 5 can adopt a tension spring that can withstand a large tensile force and has good resilience.

[0069] Regarding the specific implementation of the tooth meshing structure 3, based on the above embodiment, please refer to Figure 1 The tooth meshing structure 3 includes a pair of tooth plates 30, which are respectively extended in the radial direction of the rotating shaft 8 of the pair of bag hanging plates 2. The two sides of the pair of tooth plates 30 facing each other are respectively arranged on the opposite sides of the pair of bag hanging plates 2, and the two sides facing each other of the pair of tooth plates 30 are meshed and connected by teeth 31.

[0070] The tooth meshing structure 3 adopts the above-mentioned structural setting, which has the following advantages. First, a pair of tooth plates 30 realizes power transfer between the two rotating shafts 8 in space, that is, realizes power transmission between a pair of bag hanging plates 2, so that the relative movement of the pair of bag hanging plates 2 can be achieved by simply driving the rear bag hanging plate 2b; second, the pair of tooth plates 30 are relatively arranged along the radial direction of the rotating shaft 8, which not only makes the structural layout more compact, but also reduces the power transmission path and energy loss, which is conducive to improving the power transmission efficiency between the pair of bag hanging plates 2.

[0071] It should be noted that when a pair of bag hanging plates 2 are not subjected to external driving force, the tops of the pair of bag hanging plates 2 are separated from each other to form a certain distance. The size of this distance should be set according to the width of the closed packaging bag so that the distance between the pair of bag hanging plates 2 meets the distance requirements for positioning and installing the packaging bag.

[0072] To adapt to packaging bags of different sizes, please refer to the above examples. Figure 1 The second side of the slider 1 is provided with a pair of detachable positioning posts 10 located between the pair of bag hanging plates 2. When the pair of bag hanging plates 2 are both in their initial positions, the pair of positioning posts 10 are in contact with the corresponding pair of bag hanging plates 2. Therefore, the present invention can adjust the spacing between the pair of bag hanging plates 2 by adjusting the position of the pair of positioning posts 10, thereby adapting to packaging bags of different sizes.

[0073] In order to prevent the packaging bags from falling off during transportation and to achieve smooth transportation of the packaging bags, based on any of the above embodiments, the present application further includes a pair of clamping assemblies 9, which are respectively arranged on the top of a pair of bag hanging plates 2. The clamping assemblies 9 include a fixed clamp 90 and a push-pull mechanism. The fixed clamp 90 is foldably arranged on the bag hanging plate 2, and is provided with a through hole for the positioning member 4 to pass through. The push-pull mechanism is connected to the fixed clamp 90 and is used to drive the fixed clamp 90 to rotate to engage with or disengage the positioning member 4.

[0074] Specifically, such as Figure 1 As shown, reversible fixing clips 90 are installed at the top of both the front bag hanging plate 2a and the rear bag hanging plate 2b. These fixing clips 90 are perforated, allowing the positioning members 4 on the bag hanging plate 2 to pass through the perforations and exit the fixing clips 90. Each fixing clip 90 corresponds to a push-pull mechanism, the driving end of which is connected to the fixing clip 90. Therefore, when installing a packaging bag, the push-pull mechanism is controlled to cause the fixing clips 90 to flip outward, moving the perforated portion of the fixing clip 90 away from the bag hanging plate 2, disengaging the positioning members 4 from the fixing clips 90. The two bag hanging holes of the packaging bag are then correspondingly fitted onto the pair of positioning members 4. The push-pull mechanism is then controlled to cause the fixing clips 90 to flip inward, returning the perforated portion of the fixing clip 90 to its initial position, so that the fixing clips 90 clamp the packaging bag mounted on the positioning members 4. When removing the packaging bag, the above-described operation is reversed.

[0075] Therefore, compared with the existing conveying clamp that only locates and installs the packaging bag through the positioning part 4, the present application adds a clamping component 9, which not only ensures that the packaging bag is stably and reliably fixed on the conveying clamp, but also prevents the packaging bag from falling off the positioning part 4 during the conveying process, thereby ensuring that the packaging bag is smoothly transported to each process station, greatly improving the yield rate, and the previous process no longer requires the positioning part 4 for positioning, making the equipment easier to process and low-cost.

[0076] In this embodiment, please refer to Figure 1 One side of the fixing clip 90 is rotatably connected to the bag hanging plate 2 through a pin shaft A91 perpendicular to the positioning member 4, and a through hole is set on the other side to enable the fixing clip 90 to be flipped relative to the bag hanging plate 2 while being able to be taken away from the through hole and detached from the positioning member 4 in time.

[0077] Furthermore, a notch is provided at a position of the through hole away from the pin shaft A91 , and the notch contacts and fits with the outer surface of the positioning member 4 , making it easier for the positioning member 4 to detach from the fixing clamp 90 .

[0078] Regarding the specific implementation of the push-pull mechanism, in this embodiment, please refer to Figure 3 and Figure 4 The push-pull mechanism includes a cavity 92, a push rod 93 and a hinged rod 94. The cavity 92 is arranged on the side of the bag hanging plate 2 facing away from the fixing clamp 90, and extends along the axial direction of the parallel positioning member 4. The push rod 93 is slidably arranged inside the cavity 92 along the length direction of the cavity 92. The hinged rod 94 is arranged inside the cavity 92, and one end of the hinged rod 94 is hinged to the push rod 93, and the other end passes through the bag hanging plate 2 to hinge the fixing clamp 90.

[0079] Specifically, taking the push-pull mechanism on the front side bag hanging plate 2a as an example, a fixing clamp 90 is provided on one side of the front side bag hanging plate 2a, and one side of the fixing clamp 90 is rotatably connected to the front side bag hanging plate 2a through a pin shaft A91, and the other side of the front side bag hanging plate 2a is fixedly connected to the first end of the cavity 92, and the second end of the cavity 92 extends a certain distance away from the front side bag hanging plate 2a along the axial direction of the positioning member 4 to form a accommodating space for accommodating a push rod 93 and a hinge rod 94, and the push rod 93 is slidingly arranged along the length direction of the cavity 92, and the push rod 93 is hinged to one end of the hinge rod 94 through a pin shaft B95 toward one end of the front side bag hanging plate 2a, and a through hole is provided at the position of the front side bag hanging plate 2a facing the accommodating space of the cavity 92, and the other end of the hinge rod 94 passes through the through hole and is hinged to the fixing clamp 90 through the pin shaft B95. Thus, when the fixing clamp 90 needs to be opened, the push rod 93 is pushed forward, so that the push rod 93 moves closer to the front bag hanging plate 2a, driving the hinged rod 94 to push open the fixing clamp 90; when the fixing clamp 90 needs to be closed, the push rod 93 is pulled backward, so that the push rod 93 moves away from the front bag hanging plate 2a, driving the hinged rod 94 to pull back the fixing clamp 90. Thus, the push rod 93 installed in the cavity 92 is pushed and pulled, and the hinged rod 94 is used to allow the fixing clamp 90 and the push rod 93 to rotate relative to each other within a certain range, thereby realizing the opening and closing of the fixing clamp 90.

[0080] In this embodiment, please refer to Figure 3 The cavity 92 is provided with a slide groove 96 extending along its length direction, and the push rod 93 is provided with a push column 97, which passes through the slide groove 96 and extends out of the cavity 92.

[0081] Specifically, a slide groove 96 is provided on the outer wall of the cavity 92. The slide groove 96 extends along the length of the cavity 92, and the interior of the cavity 92 is connected to its exterior through the slide groove 96. That is, the slide groove 96 penetrates the outer wall of the cavity 92 in a direction perpendicular to the length of the cavity 92. One end of the push rod 93 is fixed to the push rod 93 inside the cavity 92, and the other end extends out of the cavity 92 through the slide groove 96. Thus, the push column 97 acts as the control portion of the push rod 93. The control portion extends from the interior of the cavity 92, making it convenient to manually push and pull the control portion to control the opening and closing of the fixing clamp 90. In addition, the slide groove 96 acts as a slide rail, limiting the path for the push column 97 to slide back and forth, thereby preventing the push rod 93 from deviating during its forward and backward movement, which would cause the fixing clamp 90 to open and close unreliably.

[0082] In this embodiment, the chute 96 is arranged near the end of the cavity 92 away from the bag hanging plate 2, which is conducive to maximizing the length space of the cavity 92 to arrange the chute 96.

[0083] Preferably, the cavity 92 is provided with a through hole along its length, which is equivalent to an accommodating space for accommodating the push rod 93 and the hinge rod 94. The cavity 92 with this structure is not only convenient for processing and manufacturing the cavity 92, but also convenient for installing the push rod 93 and the hinge rod 94.

[0084] For further information, please refer to Figure 1 The end of the cavity 92 away from the bag hanging plate 2 is provided with a blocking plate 99 that blocks the through hole. This allows foreign matter to enter the cavity 92 and block the movement of the push rod 93 or the hinged rod 94. It should be noted that the end of the cavity 92 near the bag hanging plate 2 is connected to the through hole in the bag hanging plate 2, so that the hinged rod 94 located in the cavity 92 passes through the through hole and is hingedly connected to the fixing clamp 90.

[0085] In this embodiment, please refer to Figure 4 A second elastic member 98 is provided between the push rod 93 and the cavity 92. Thus, when the push post 97 is in the initial position, the second elastic member 98 is positioned between the push post 97 and the inner wall of the cavity 92. The elastic force of the second elastic member 98 in a compressed state facilitates rapid opening and closing of the fixing clamp 90. The second elastic member 98 can be a compression spring that can withstand greater pressure and deformation.

[0086] Regarding the specific structure of a pair of bag hanging plates 2, based on the above embodiment, please refer to Figure 1 and Figure 2 A pair of bag hanging plates 2 each include a gear plate 21 and a bag hanging arm 20 that are connected as one body, and the two are arranged in a direction from top to bottom.

[0087] Specifically, the front bag hanging plate 2a is composed of a front gear plate 21 and a front bag hanging arm 20, while the rear bag hanging plate 2b is composed of a rear gear plate 21 and a rear bag hanging arm 20. The tops of the front and rear bag hanging arms 20 and 20 are both equipped with a clamping assembly 9 and a positioning member 4 to firmly clamp the packaging bags. The opposing sides of the front and rear gear plates 21 are meshed and connected by a toothed structure 3, and a guide leg 6 is provided at the bottom of the rear gear plate 21. Therefore, the bag hanging plate 2 composed of the above two components is not only convenient for processing and manufacturing of the bag hanging plate 2, but also convenient for assembly and disassembly of the various components on the bag hanging plate 2.

[0088] Regarding the specific connection method between the slider 1 and the synchronous belt 13, based on any of the above embodiments, please refer to Figure 2 The first side of the slider 1 is provided with two sets of rollers spaced apart from each other from top to bottom. The two sets of rollers are used to be mounted on two guide rails 14 on both sides of the synchronous belt 13.

[0089] Specifically, a first set of rollers 11 is provided on the upper portion of the first side of the slider 1, and a second set of rollers 12 is provided on the lower portion of the first side of the slider 1. A fixing hole is provided on the slider 1 between the first set of rollers 11 and the second set of rollers 12. The fasteners on the synchronous belt 13 cooperate with the fixing holes on the slider 1 to secure the slider 1 to the synchronous belt 13, thereby securing the entire conveying fixture to the synchronous belt 13. In addition, guide rails 14 are provided on both sides of the synchronous belt 13. The rollers in the first set of rollers 11 are all mounted on the guide rails 14 located above the synchronous belt 13, while the rollers in the second set of rollers 12 are all mounted on the guide rails 14 located below the synchronous belt 13. This allows the slider 1 to move smoothly along the two guide rails 14 driven by the synchronous belt 13, thereby smoothly conveying the packaging bags.

[0090] Therefore, compared with the existing conveying clamp that uses a sliding connection between the slider 1 and the guide rail 14 on the side of the synchronous belt 13, the present application uses a rolling connection between the roller and the guide rail 14 to realize the clamp transmission. Rolling friction replaces sliding friction, the friction resistance is small, the friction particles can be reduced, and it is beneficial to the packaging bags in a sterile environment.

[0091] It is understandable that if the gap between the roller and the guide rail 14 is too small, the friction resistance will increase and the wear of the guide rail 14 will be aggravated. If the gap between the roller and the guide rail 14 is too large, the accuracy and smoothness of the roller movement will be reduced. Therefore, adjusting the gap between the roller and the guide rail 14 to an appropriate range will help ensure the smooth, accurate and stable movement of the slider 1.

[0092] In this embodiment, please refer to Figure 5Either or both roller groups are eccentric rollers. The eccentric rollers can be used to adjust the gap between the rollers and the guide rail 14, thereby enabling smooth, precisely positioned, and stable movement of the slider 1 on the timing belt 13, thereby enabling the conveyor fixture to smoothly convey the packaging bags. It should be noted that the number of rollers in each roller group is not unique and can be adaptively adjusted based on actual working conditions.

[0093] If the rollers in the first group of rollers 11 are set as eccentric rollers, so that the eccentric rollers are placed on the upper side of the synchronous belt 13, it is convenient to manually adjust the eccentricity of the eccentric rollers, and further facilitate the adjustment of the gap between the rollers and the guide rail 14.

[0094] If the rollers in the second group of rollers 12 are set as eccentric rollers, the eccentric rollers are placed on the lower side of the synchronous belt 13, and by adjusting the eccentricity of the eccentric rollers, the eccentric rollers are appropriately pre-tightened on the guide rail 14, thereby improving the load-bearing capacity of the second group of rollers 12, and further making the overall conveying fixture more firmly installed on the guide rail 14.

[0095] If the rollers in the first group of rollers 11 and the second group of rollers 12 are both eccentric rollers, the slider 1 can be moved more smoothly, accurately and stably on the synchronous belt 13, thereby greatly improving the stability of the conveying clamp in conveying the packaging bag and reducing vibration.

[0096] Optionally, the rollers in the two groups of rollers are V-shaped rollers, and the two guide rails 14 on the edges of both sides of the synchronous belt 13 are V-shaped guide rails 14. The rolling contact between the V-shaped rollers and the V-shaped guide rails 14 has the characteristics of small friction resistance, small vibration and fast movement speed, which further improves the stability and efficiency of the conveying clamp in conveying the packaging bags.
