Description

Technical Field

[0001] This application relates to the technical field of nalbuphine production, and particularly to an automatic packaging device for nalbuphine injection. Background Art

[0002] In the refining stage of the nalbuphine production process, the synthesized crude nalbuphine is mainly purified by removing impurities, and then nalbuphine is stored in ampoules or vials in the form of a solution for storage, packaging, and transportation.

[0003] The existing ampoule automatic packaging equipment usually includes a vial conveyor line and a box conveyor line. The vial conveyor line is usually located above the packaging conveyor line; a sorting device is provided on the box conveyor line to sort and place plastic boxes one by one on the box conveyor line, and a labeling device for labeling ampoules is provided on the vial conveyor line. After the labeling operation of the ampoules is completed on the vial conveyor line, the ampoules will be transferred and placed on the plastic boxes by a transfer sprocket provided at the end of the vial conveyor line. Then the plastic boxes are conveyed forward to a sealing unit for sealing, and then automatically boxed by a packaging unit to complete the automatic packaging operation of the ampoules.

[0004] However, when the ampoules are transferred from the transfer sprocket to the plastic boxes, there is a height difference when the ampoules are transferred from the vial conveyor line through the transfer sprocket to the box conveyor line. The ampoules may crack when hitting external objects under the action of gravity, and there may even be a risk of broken vials, which poses a certain safety hazard and needs to be improved. Summary of the Invention

[0005] Based on this, this application provides an automatic packaging device for nalbuphine injection, which can reduce the possibility of cracks or even breakage of the ampoules when transferring the ampoules, and ensure production safety.

[0006] The automatic packaging device for nalbuphine injection provided by this application adopts the following technical solutions:

[0007] An automatic packaging device for nalbuphine injection includes an equipment assembly. The equipment assembly is provided with a vial conveyor line and a box conveyor line. The vial conveyor line is provided with a labeling device for labeling ampoules, and the end of the vial conveyor line is set as a first loading area; the front end of the box conveyor line is provided with a loading device for placing plastic boxes and a sorting device for sorting plastic boxes, and the end of the box conveyor line is set as a second loading area;

[0008] The equipment assembly is also provided with a transfer device, a film sealing device and a blanking conveyor line. Among them, the transfer device includes a rotating frame mechanism rotatably installed on the equipment assembly and a driving mechanism for driving the rotating frame mechanism to rotate. A plurality of station groove areas are evenly distributed on the outer peripheral surface of the rotating frame mechanism. A clamping mechanism for clamping and fixing the plastic box is arranged inside each station groove area, and the clamping mechanism is rotatably installed on the rotating frame mechanism; the film sealing device is used for sealing the open side of the plastic box. When the rotating frame mechanism rotates, the station groove areas sequentially pass through the first feeding area, the second feeding area, the film sealing device and the blanking conveyor line.

[0009] By adopting the above technical solution, when the automatic packaging equipment of the present application is in use, after the ampoule bottles are automatically labeled by the labeling device on the bottle body conveyor line, they can be conveyed by the bottle body conveyor line to the station groove area located in the first feeding area; then the rotating frame mechanism rotates, and can drive each ampoule bottle to transfer to the second feeding area. In this process, the possibility of the ampoule bottles colliding with external equipment is relatively low, which is beneficial to reducing the possibility of the ampoule bottles cracking or even breaking, and ensuring production safety. The plastic boxes for installing the ampoule bottles are sorted one by one by the sorting device and placed on the box body conveyor line. After the station groove area containing the ampoule bottles rotates to the second feeding area, the box body conveyor line conveys the plastic boxes into the station groove area. Then the rotating frame mechanism continues to rotate, transfers the plastic boxes to the film sealing device for film sealing, and finally transfers them to the blanking conveyor line, which can automatically complete a series of packaging processes such as labeling, box loading and film sealing of the ampoule bottles, and realize automated production.

[0010] Optionally, the rotating frame mechanism includes a central rotating cylinder and a plurality of outer plate frames evenly distributed on the outer peripheral side of the central rotating cylinder. Adjacent outer plate frames are arranged at intervals to form station groove areas; the width of the outer plate frame is smaller than the length of the ampoule bottle;

[0011] The transfer device further includes two side guard plates fixedly arranged. The two side guard plates are respectively located on two opposite sides of the outer plate frame, and the distance between the two side guard plates is adapted to the length of the ampoule bottle; the end of the bottle body conveyor line extends partially between the side guard plate and the outer plate frame.

[0012] By adopting the above technical solution, setting two side guard plates and making the distance between the two side guard plates adapted to the length of the ampoule bottle can reduce the possibility of the plastic box shifting or falling when the plastic box enters the station groove area, and then ensure the smooth transfer of the plastic box to the next station when the outer plate frame rotates.

[0013] Optionally, the clamping mechanism includes a fixed column member and a movable column member. The fixed column member is vertically fixed with a rotating shaft, and the fixed column member is rotatably connected to the central rotating cylinder through the rotating shaft;

[0014] The cross-sectional shape in the middle of the rotating shaft is rectangular. The movable column member is provided with a rectangular groove. The movable column member is movably sleeved on the rotating shaft through the rectangular groove, and a hard spring is provided between the movable column member and the rotating shaft. The hard spring is used to force the movable column member to normally abut against the fixed column member, so as to force the movable column member and the fixed column member to jointly clamp and fix the plastic box.

[0015] The equipment assembly is provided with a fixed base, and the fixed base is provided with a control mechanism. When the station groove area is located in the second loading area, the control mechanism is located outside the clamping mechanism and is used to force the movable column member to move away from the fixed column member.

[0016] By adopting the above technical solution, when the station groove area is located in the second loading area, by controlling the action of the control mechanism to force the movable column member to move away from the fixed column member, the clamping mechanism can be in an open state. At this time, the plastic box conveyed to the station groove area via the box conveyor line can enter between the movable column member and the fixed column member. Then, by forcing the control mechanism to reset, the movable column member can be reset to a state of abutting against the fixed column member under the elastic force of the hard spring, so that the movable column member and the fixed column member jointly clamp the plastic box and maintain the clamping state, so as to facilitate the smooth transfer of the plastic box to the next station when the outer plate frame rotates.

[0017] Optionally, the control mechanism includes a first linear cylinder fixed to the fixed base and a pushing member fixed to the movable end of the first linear cylinder. The movable column member is partially provided with an inclined guide portion. When the first linear cylinder acts, the pushing member abuts against the inclined guide portion and forces the movable column member to move away from the fixed column member.

[0018] By adopting the above technical solution, when the first linear cylinder acts, the pushing member at the movable end of the first linear cylinder can abut against the inclined guide portion of the movable column member, and then through the cooperation between the inclined guide portion and the movable column member, the movable column member is forced to move away from the fixed column member, so that the clamping mechanism is in an open state.

[0019] Optionally, a load-bearing plate is movably embedded in the inner side wall of the station groove area. The load-bearing plate and the clamping mechanism are arranged on two opposite inner walls of the station groove area, and a plurality of recessed grooves are provided on the side surface of the load-bearing plate close to the clamping mechanism. The recessed grooves are used for the ampoule bottles to sink into and be positioned.

[0020] A structural groove for weight reduction is provided inside the outer plate frame. The side surface of the load-bearing plate away from the clamping mechanism is provided with an insertion post portion. The insertion post portion penetrates into the structural groove, and an anti-detachment portion is provided at one end of the insertion post portion away from the clamping mechanism. When the station groove area where the load-bearing plate is located is in the first loading area, the load-bearing plate is horizontally arranged. At this time, the anti-detachment portion is spaced from the inner wall of the structural groove close to the station groove area.

[0021] By adopting the above technical solution, when the station tank area is located in the first loading area, the ampoule bottles conveyed to the station tank area via the bottle conveyor line can be transferred to the carrier plate, and the arrangement of the recessed grooves on the carrier plate can play a role in positioning the ampoule bottles to a certain extent, so that the ampoule bottles are kept at intervals. It should be noted here that when the plastic box enters the station tank area later, it is in an inverted state. Then, as the outer plate frame rotates, the plastic box and each ampoule bottle rotate around the central axis of the outer plate frame, enabling each ampoule bottle to smoothly enter each partition area of the plastic box. Moreover, after the carrier plate rotates and under the action of its own gravity, it can naturally move downward to play a role in pressing the bottles, which is beneficial to smoothly pressing each ampoule bottle into the corresponding partition areas of the plastic box for subsequent film sealing operations.

[0022] Optionally, a plurality of arc-shaped guide plates are provided on the side of the side guard plate close to the other side guard plate. The adjacent arc-shaped guide plates are spaced from each other and form partition channels for separating the ampoule bottles; each arc-shaped guide plate is located between the first loading area and the second loading area. When the station tank area moves from the first loading area to the second loading area, each ampoule bottle enters each partition channel respectively.

[0023] By adopting the above technical solution, by providing a plurality of arc-shaped guide plates to form partition channels, during the process that the outer plate frame rotates to drive the station tank area to move from the first loading area to the second loading area, each ampoule bottle can move along the corresponding partition channel, which is beneficial to reducing the possibility of the ampoule bottles overlapping each other in the second loading area and ensuring that the subsequent plastic box smoothly enters the station tank area in the second loading area and is clamped and fixed by the clamping mechanism.

[0024] Optionally, a connecting rod member is sleeved on the outer peripheral side of the rotating shaft. The connecting rod member is located on the side of the fixed column member away from the movable column member, and the connecting rod member is circumferentially linked with the rotating shaft; the end of the connecting rod member is rotatably connected with a sliding rod member, the end of the sliding rod member is hinged with a sliding seat, the sliding seat is slidably connected to the central rotating cylinder, and when the station tank area rotates to the outside of the film sealing device, the sliding direction of the sliding seat is arranged in the same direction as the horizontal direction;

[0025] A linkage groove is provided on the side of the sliding seat away from the central rotating cylinder. A switching mechanism is fixed to the equipment assembly. When the station tank area moves to the outside of the film sealing device, the switching mechanism cooperates with the linkage groove to realize the switching of the clamping mechanism from the station tank area to the film sealing device.

[0026] By adopting the above technical solution, when the outer plate rack rotates to bring the station slot area to the outside of the film sealing device, the switching mechanism can cooperate with the linkage slot of the sliding seat. Then, by controlling the action of the switching mechanism, the sliding seat and the sliding rod member can be pulled away from the corresponding station slot area, causing the connecting rod member to rotate. During this process, since the connecting rod member is circumferentially linked with the rotating shaft, the movement of the sliding seat can drive the rotating shaft to rotate, thereby forcing the clamping mechanism to smoothly drive the plastic box and the ampoule bottle to rotate to the film sealing device for film sealing operation. It can be understood that after the film sealing operation is completed, by controlling the switching mechanism to reset, the clamping mechanism can send the film-sealed plastic box back to the station slot area, facilitating the subsequent transfer of the plastic box by the outer plate rack to the blanking conveyor line for the final packaging operation.

[0027] Optionally, the switching mechanism includes a second linear cylinder fixed to the fixed base and an arc-shaped pulling plate fixed to the movable end of the second linear cylinder. The linkage slot is arranged in an arc shape. When the station slot area moves to the outside of the film sealing device, the arc-shaped pulling plate is matched and enters the linkage slot.

[0028] By adopting the above technical solution, by setting the arc-shaped pulling plate, when the station slot area moves to the outside of the film sealing device, the arc-shaped pulling plate can be matched and enter the linkage slot. At this time, by controlling the action of the second linear cylinder, the cooperation between the arc-shaped pulling plate and the linkage slot can make the sliding seat follow the action of the second linear cylinder, thereby smoothly driving the clamping mechanism to switch between the station slot area and the film sealing device.

[0029] Optionally, the equipment assembly fixing frame is provided with a bottle pressing roller, and the bottle pressing roller is located outside the film sealing device; when the clamping mechanism switches from the station slot area to the film sealing device, the ampoule bottle passes under the bottle pressing roller.

[0030] By adopting the above technical solution, when the clamping mechanism switches from the station slot area to the film sealing device, the presence of the bottle pressing roller can ensure that each ampoule bottle is stably located in each partition area of the plastic box, so as to ensure the smooth film sealing of the subsequent plastic box and reduce the defective rate.

[0031] Optionally, the feeding device includes a feeding platform for placing stacked plastic boxes. A limiting frame plate is arranged on one side of the feeding platform close to the sorting device, and a pushing mechanism is arranged on the side of the feeding platform far from the sorting device for forcing the plastic box to move in the direction close to the limiting frame plate;

[0032] The sorting device includes a third linear cylinder fixedly installed on the feeding platform and a mounting plate arranged at the movable end of the third linear cylinder. A plurality of negative pressure suction nozzles are fixed on the mounting plate. When the third linear cylinder acts, the negative pressure suction nozzles enter the inner side of the limiting frame plate and suck the plastic box.

[0033] By adopting the above technical solution, stack of plastic boxes are placed on the loading platform, and the pushing mechanism can move the plastic boxes in the direction close to the limiting frame plate, ensuring that there is always a plastic box at the position of the limiting frame plate. When the sorting device operates, the third linear cylinder can drive the mounting plate to move in the direction close to the limiting frame plate, so that the negative pressure suction nozzle of the mounting plate fits on the outermost plastic box; then control the operation of the negative pressure suction nozzle, and the negative pressure suction nozzle can suck the outermost plastic box. Then, the third linear cylinder performs a reset action, and the negative pressure suction nozzle brings the plastic box to the box conveyor line, and then closes the negative pressure suction nozzle. The plastic box can fall on the box conveyor line and be conveyed forward by the box conveyor line to the second loading area.

[0034] In summary, the present application includes at least one of the following beneficial technical effects:

[0035] 1. By conveying each ampoule bottle from the bottle conveyor line to the station groove area, and then the turntable mechanism rotates to drive the ampoule bottle to transfer to the second loading area. During this process, the possibility of the ampoule bottle colliding with external equipment is relatively low, which is beneficial to reducing the possibility of the ampoule bottle having cracks or even breaking, and ensuring production safety;

[0036] 2. By making the station groove area pass through the first loading area, the second loading area, the film sealing device and the unloading conveyor line in sequence, a series of packaging processes such as labeling, box loading and film sealing of the ampoule bottle can be automatically completed, realizing automated production;

[0037] 3. By setting the operating mechanism to force the movable column member to move away from the fixed column member, the clamping mechanism located in the second loading area can be in an open state; then the plastic box enters between the movable column member and the fixed column member, and the movable column member resets under the elastic force of the hard spring, enabling the movable column member and the fixed column member to jointly clamp the plastic box and maintain the clamping state, so as to facilitate the outer plate frame to smoothly bring the plastic box to the next station when rotating.

[0051] The following further elaborates on this application in conjunction with the attached Figures 1-9 drawings for a more detailed description.

[0052] The embodiment of this application discloses an automatic packaging device for nalbuphine injection.

[0053] Refer to Figure 1, An automatic packaging device for nalbuphine injection, comprising a device assembly 1, and the device assembly 1 is provided with a bottle conveying line 2, a box conveying line 3, a transfer device 4, a film sealing device 5 and a blanking conveying line 6; wherein, the transfer device 4 includes a turntable mechanism 41, a driving mechanism 42 and side guard plates 43. Additionally, referring to Figure 2 , the turntable mechanism 41 includes a central cylinder 411 rotatably mounted on the device assembly 1 and a plurality of outer plate frames 412 integrally formed on the outer peripheral surface of the central cylinder 411. In this embodiment, the number of the outer plate frames 412 is set to 8, and all the outer plate frames 412 are equidistantly arranged along the outer peripheral side of the central cylinder 411; additionally, there is an interval between adjacent outer plate frames 412 and a working station groove area 44 is formed, and the working station groove area 44 is used for the feeding and packaging of ampoules and plastic boxes. In this embodiment, the width of the outer plate frame 412 is smaller than the length of the ampoule.

[0054] Back to Figure 1 , in this embodiment, the side guard plates 43 are acrylic plates, and the number of the side guard plates 43 is two. Each side guard plate 43 is fixedly mounted on the top of the device assembly 1; the two side guard plates 43 are respectively arranged on two opposite sides of the outer plate frame 412, and each side guard plate 43 is arranged at an interval from the outer plate frame 412; the distance between the two side guard plates 43 is set to be equal to the width of the plastic box, which is beneficial for the plastic box to smoothly enter the working station groove area 44 and be located between the two side guard plates 43, reducing the possibility of the plastic box laterally shifting or even accidentally falling in the working station groove area 44.

[0055] Back to Figure 2 , the driving mechanism 42 includes a rotary motor 421 and a driving gear 422. Among them, the rotary motor 421 is fixedly supported on the device assembly 1, and the driving gear 422 is fixed to the output end of the rotary motor 421; an outer peripheral gear ring 413 is integrally formed at one end of the central cylinder 411. The outer peripheral gear ring 413 is coaxially arranged with the central cylinder 411, and the outer peripheral gear ring 413 meshes with the driving gear 422. Furthermore, when the rotary motor 421 operates, the turntable mechanism 41 can be driven to rotate circumferentially around the central axis of the central cylinder 411 by the meshing transmission between the driving gear 422 and the outer peripheral gear ring 413, so that each working station groove area 44 can sequentially pass through the bottle conveying line 2, the box conveying line 3, the film sealing device 5 and the blanking conveying line 6.

[0056] Each outer plate frame 412 is internally provided with a structural groove 414. The provision of the structural groove 414 can reduce the overall weight of the outer plate frame 412, facilitating the smooth driving of the rotating frame mechanism 41 by the rotating motor 421 and extending the service life of the driving motor. The inner wall of each station groove area 44 is provided with an embedded groove, and the inner bottom wall of the embedded groove is provided with a communication groove communicating with the structural groove 414. The cross-sectional shape of the communication groove is rectangular; a carrier plate 45 is fitted and installed in the embedded groove. A plug post portion 451 is fixed to the side surface of the carrier plate 45. The plug post portion 451 is fitted and inserted into the communication groove and can move within the communication groove; a anti-disengagement portion 452 is provided at one end of the plug post portion 451 away from the carrier plate 45. The anti-disengagement portion 452 is normally located within the structural groove 414, and the outer diameter dimension of the anti-disengagement portion 452 is larger than the outer diameter dimension of the plug post portion 451, which can prevent the carrier plate 45 from accidentally disengaging from the embedded groove.

[0057] A plurality of recessed grooves 453 are provided on the side surface of the carrier plate 45 away from the plug post portion 451. All the recessed grooves 453 are arranged side by side and equidistantly on the surface of the carrier plate 45; when the station groove area 44 where the carrier plate 45 is located is in the first loading area, the carrier plate 45 is horizontally arranged. At this time, the recessed grooves 453 can be located on the top surface of the carrier plate 45 for the ampoule bottles to sink into and be temporarily positioned; in addition, at this time, the anti-disengagement portion 452 is spaced from the inner wall of the structural groove 414 close to the station groove area 44.

[0058] Back to Figure 1 The bottle conveyor line 2 is arranged on the top of the equipment assembly 1 for conveying ampoule bottles; the bottle conveyor line 2 includes a conveying platform 21 and two first conveyor belts 22 arranged on both side surfaces of the conveying platform 21. The conveying direction of the first conveyor belts 22 is the same as the extending direction of the conveying platform 21; a plurality of partition bars 23 are equidistantly arranged on the surface of each first conveyor belt 22. When the ampoule bottles are conveyed from the previous process to the first conveyor belt 22, they can enter the area between two adjacent partition bars 23, so as to convey each ampoule bottle at intervals forward in sequence.

[0059] Referring to Figure 3 Here, it should be noted that the end of each first conveyor belt 22 can extend between a side guard plate 43 and the outer plate frame 412, facilitating the smooth conveyance of the ampoule bottles by the first conveyor belt 22 into the station groove area 44 and enabling each ampoule bottle to sink into each recessed groove 453 for preliminary positioning; in this application, the end of the bottle conveyor line 2 is set as the first loading area.

[0060] Back to Figure 1, a labeling device 24 is also provided on the bottle body conveyor line 2. Through the labeling device 24, automatic labeling operation can be carried out on the ampoule bottles, so that the labels with relevant information of nalbuphine injection are automatically attached to the outer peripheral surface of the ampoule bottles. It should be noted here that the specific structure of the labeling device 24 in this embodiment is a conventional design in the art and is not the key point protected by this case, so it will not be elaborated in detail here.

[0061] The box body conveyor line 3 is fixedly arranged above the bottle body conveyor line 2 for conveying plastic boxes; a feeding device 31 for placing plastic boxes and a sorting device 32 for sorting plastic boxes are arranged at the front end of the box body conveyor line 3, and the end of the box body conveyor line 3 is set as the second feeding area. Among them, referring to Figure 4 , the feeding device 31 includes a feeding platform 311, a limiting frame plate 312 and a pushing mechanism. The feeding platform 311 is fixedly arranged on the top of the equipment assembly 1. When an operator feeds materials, a stack of plastic boxes can be placed flat on the feeding platform 311.

[0062] The pushing mechanism includes a linear module 313 fixed to the feeding platform 311 and a pushing seat 314 arranged at the movable end of the linear module 313. When the linear module 313 resets to the initial position, the pushing seat 314 can be located at one side end of the feeding platform 311 far from the box body conveyor line 3; the limiting frame plate 312 is fixed to the top of the feeding platform 311, and the limiting frame plate 312 is located at one side end of the feeding platform 311 close to the box body conveyor line 3. In this embodiment, the limiting frame plate 312 is arranged in a U shape, and the internal width dimension of the limiting frame plate 312 is slightly smaller than the width of the plastic box. When the linear module 313 acts, the pushing seat 314 can gradually push the plastic box in the direction close to the limiting frame plate 312. At this time, the plastic box closest to the limiting frame plate 312 can be blocked by the limiting frame plate 312, playing a role in limiting.

[0063] Referring to Figure 5 , the sorting device 32 includes a third linear cylinder 321 fixedly arranged above the feeding platform 311 and a mounting plate 322 fixed to the movable end of the third linear cylinder 321. Among them, the third linear cylinder 321 is in a normally retracted state. At this time, the mounting plate 322 is located above the box body conveyor line 3; a plurality of negative pressure suction nozzles 323 are fixed on the mounting plate 322. When the third linear cylinder 321 acts, it can drive the mounting plate 322 into the inner side of the limiting frame plate 312 and make the negative pressure suction nozzles 323 abut against the plastic box closest to the limiting frame plate 312; then the negative pressure suction nozzles 323 operate and generate suction to adsorb the plastic box. The reset of the third linear cylinder 321 can make the plastic box pass through the limiting frame plate 312 and move above the box body conveyor line 3. Then the negative pressure suction nozzles 323 are closed, and the plastic box can fall on the box body conveyor line 3 and be carried forward by the box body conveyor line 3. It should be noted here that the plastic box will be in an inverted state when it falls on the box body conveyor line 3 in this embodiment.

[0064] Referring to Figure 6 , when the rotating motor 421 drives the turntable mechanism 41 to rotate and the station slot area 44 enters the second loading area at the end of the box conveyor line 3 from the first loading area at the end of the bottle conveyor line 2, the plastic box can be conveyed to the station slot area 44 via the box conveyor line 3. In addition, a clamping mechanism 7 is provided inside each station slot area 44. The clamping mechanism 7 is used to clamp and fix the plastic box and can maintain the clamping state of the plastic box when the outer plate frame 412 rotates, which is beneficial to smoothly transfer the plastic box and each ampoule bottle to the next station; the clamping mechanism 7 and the load-bearing plate 45 in a station slot area 44 can be respectively arranged on two opposite inner walls of the station slot area 44.

[0065] Specifically referring to Figure 7 , the clamping mechanism 7 includes a fixed column member 71 and a movable column member 72. A rotating shaft 73 is vertically fixed to the fixed column member 71, and a rotating seat 415 is provided on the side of the central rotating cylinder 411. By rotatably connecting the rotating shaft 73 to the rotating seat 415, the fixed column member 71 can be rotated and connected to the central rotating cylinder 411; it should be noted here that the axis line of the rotating shaft 73 of the fixed column member 71 will be perpendicular to the axis line of the rotating shaft 73 of the central rotating cylinder 411.

[0066] In this embodiment, the end face shape of the middle part of the rotating shaft 73 is rectangular. The movable column member 72 is provided with a rectangular groove 721 penetrating through both sides. The movable column member 72 can be movably sleeved on the rotating shaft 73 through the rectangular groove 721, so that the movable column member 72 can only move along the axis direction of the rotating shaft 73 and the circumferential rotation of the movable column member 72 around the rotating shaft 73 is restricted. In addition, a hard spring 74 is also sleeved on the outer peripheral side of the rotating shaft 73. The hard spring 74 is located on the side of the movable column member 72 away from the fixed column member 71; one end of the hard spring 74 abuts against the movable column member 72, and the other end abuts against the rotating seat 415, so that an elastic force acting on the movable column member 72 can be always generated, and then the movable column member 72 is forced to normally abut against the fixed column member 71.

[0067] In the initial state, the movable column member 72 and the fixed column member 71 are normally located inside the station slot area 44; a fixed base 11 is fixed to the top of the equipment assembly 1 (refer to Figure 1 ), and a control mechanism 12 is provided on the fixed base 11. When the station slot area 44 moves to the second loading area, the control mechanism 12 can be located outside the clamping mechanism 7. By controlling the action of the control mechanism 12, the movable column member 72 can be forced to move in a direction away from the fixed column member 71. At this time, the clamping mechanism 7 is in an open state, which is beneficial for the plastic box to enter the station slot area 44 and be located between the fixed column member 71 and the movable column member 72, so that the clamping mechanism 7 can smoothly clamp and fix the plastic box.

[0068] Specifically, referring to Figure 7, the operating mechanism 12 includes a first linear cylinder 121 fixed to the fixed base 11 and a pushing member 122 fixed to the movable end of the first linear cylinder 121. A partial inclined guide portion 722 is provided on one side of the movable column member 72 close to the pushing member 122, and the pushing member 122 is disposed opposite to the inclined guide portion 722 along its moving direction. When the first linear cylinder 121 operates, the pushing member 122 can abut against the inclined guide portion 722, thereby forcing the movable column member 72 to move away from the fixed column member 71, so that the clamping mechanism 7 is in an open state. After the plastic box enters between the fixed column member 71 and the movable column member 72, by controlling the reset action of the first linear cylinder 121, after the pushing member 122 disengages from the inclined guide portion 722, the movable column member 72 is reset to abut against the fixed column member 71 under the elastic force of the hard spring 74, so as to be able to firmly clamp the plastic box.

[0069] At the same time, referring to Figure 8 , it is worth mentioning that in this embodiment, a plurality of arc-shaped guide plates 431 are provided on the side surface of each side guard plate 43 close to the other side guard plate 43, and each arc-shaped guide plate 431 is integrally formed with the side guard plate 43; one end of each arc-shaped guide plate 431 in the arc direction is located in the first feeding area, and the other end of the arc-shaped guide plate 431 in the arc direction extends to the second feeding area, and the adjacent side guard plates 43 are spaced apart from each other and a partition area channel is formed. After each ampoule bottle enters the station groove area 44 located in the first feeding area respectively, each ampoule bottle is initially positioned in each recessed groove 453 respectively, and then during the rotation of the outer plate frame 412, each ampoule bottle can enter each partition area channel respectively, which can play a role of separating and guiding, reduce the possibility of the ampoule bottles overlapping each other in the second feeding area, and ensure that the plastic box can smoothly enter the station groove area 44 in the second feeding area and be clamped and fixed by the clamping mechanism 7.

[0070] Returning to Figure 1 , the film sealing device 5 is arranged at a position opposite to the first feeding area and is used for sealing the open side of the plastic box; it should be noted that the specific structure of the film sealing device 5 is commonly involved in the art and is not the key point to be protected in this case, so it will not be elaborated in detail here. Referring to Figure 2 , it should be noted here that during the rotation of the outer plate frame 412 to transfer the station groove area 44 from the second feeding area to the film sealing device 5, the plastic box and each ampoule bottle are turned over, so that each ampoule bottle falls into each partition area of the plastic box. At the same time, during this process, the bearing plate 45 can move downward under its own gravity and press each ampoule bottle, so that the ampoule bottle completely enters the partition area, which is convenient for the subsequent film sealing operation of the ampoule bottle. When the anti-detachment portion 452 abuts against the inner wall of the structure groove 414 and the bearing plate 45 is in the limit position, the bearing plate 45 can just fit against the plastic box.

[0071] Referring to Figure 9, a connecting rod member 75 is sleeved on the outer peripheral side of the rotating shaft 73. The connecting rod member 75 is located on the side of the fixed column member 71 away from the movable column member 72. The connecting rod member 75 is provided with a sleeve groove for the rotating shaft 73 to pass through. The shape of the sleeve groove is a rectangle adapted to the rotating shaft 73, thereby realizing the circumferential linkage setting of the connecting rod member 75 and the rotating shaft 73, that is, when the connecting rod member 75 rotates, it can drive the rotating shaft 73 to rotate together. In addition, a sliding rod member 76 is rotatably connected to the free end of the connecting rod member 75. The end of the sliding rod member 76 away from the connecting rod member 75 is hinged with a sliding seat 77. The sliding seat 77 is slidably connected to the side end face of the central rotating cylinder 411, and when the working station groove area 44 rotates to the outside of the film sealing device 5, the sliding direction of the sliding seat 77 can be set in the same direction as the horizontal direction. In addition, a linkage groove 771 is provided on the side face of the sliding seat 77 away from the central rotating cylinder 411. The linkage groove 771 is an arc-shaped groove, and the axis of the arc of the linkage groove 771 coincides with the axis of the rotating shaft 73 of the central rotating cylinder 411.

[0072] The equipment assembly 1 is provided with a switching mechanism 13. The switching mechanism 13 includes a second linear cylinder 131 fixed to the fixed base 11 and an arc-shaped pull plate 132 fixed to the movable end of the second linear cylinder 131. The shape of the arc-shaped pull plate 132 is adapted to the shape of the linkage groove 771. When the turntable mechanism 41 drives the working station groove area 44 to move to the outside of the film sealing device 5, the arc-shaped pull plate 132 can enter the inside of the linkage groove 771. By controlling the action of the second linear cylinder 131 to pull the sliding seat 77 to move in the direction close to the center of the central rotating cylinder 411, the entire clamping mechanism 7 can be driven to rotate around the central axis of the rotating shaft 73, thereby switching the clamping mechanism 7 from the working station groove area 44 to the film sealing device 5 to facilitate the film sealing operation of the plastic box.

[0073] In this embodiment, the rotation angle of the clamping mechanism 7 is 90°. After the clamping mechanism 7 rotates 90°, the side face of the clamping mechanism 7 can abut against the side face of the central rotating cylinder 411, thereby restricting the further rotation of the clamping mechanism 7. Refer to Figure 8 , in addition, it should be noted here that an avoidance opening 432 is provided on the side guard plate 43 close to the film sealing device 5 among the two side guard plates 43. When the working station groove area 44 moves to the outside of the film sealing device 5, by providing the avoidance opening 432, the clamping mechanism 7 can be smoothly switched to the film sealing device 5 for film sealing operation.

[0074] In addition, back to Figure 8 , the equipment assembly 1 is fixedly provided with a rotatable bottle pressing roller 14. The bottle pressing roller 14 is located outside the film sealing device 5. When the clamping mechanism 7 is switched from the working station groove area 44 to the film sealing device 5, each ampoule bottle can pass under the bottle pressing roller 14 in sequence. The setting of the bottle pressing roller 14 can further press the ampoule bottle completely into the partition area, facilitating the subsequent film sealing operation of the ampoule bottle.

[0075] Back to Figure 6, the blanking conveyor line 6 is fixedly installed on the top of the equipment assembly 1, and the blanking conveyor line 6 is located at the rear end of the film sealing device 5 along the moving direction of the station slot area 44; the fixed base 11 is also provided with a reset column member (not shown in the figure). When the plastic box to complete the film sealing operation enters the station of the blanking conveyor line 6 along with the station slot area 44, the part of the movable column member 72 protruding from the fixed column member 71 can automatically abut against the reset column member and switch the clamping mechanism 7 to the open state. This open state can be for an instant or can be maintained for a period of time; based on this, the plastic box can automatically fall onto the blanking conveyor line 6 under its own gravity and is conveyed forward by the blanking conveyor line 6 to enter the subsequent final packaging operation area.

[0076] The above is the preferred embodiment of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
