Description

Technical Field

[0001] The present application relates to the technical field of nalbuphine production, and in particular to an automatic packaging device for nalbuphine injection. Background Art

[0002] The refining stage of the nalbuphine production process mainly involves removing impurities and purifying the synthetic crude nalbuphine, and then storing the nalbuphine in the form of a solution in ampoules or vials for storage, packaging and transportation.

[0003] The automatic packaging equipment for ampoule bottles in the prior art usually includes a bottle conveyor line and a box conveyor line. The bottle conveyor line is usually located above the packaging conveyor line; a sorting device is provided on the box conveyor line to sort the plastic boxes one by one and place them on the box conveyor line, and a labeling device is provided on the bottle conveyor line to label the ampoule bottles. After the ampoule bottles complete the labeling operation on the bottle conveyor line, a transfer sprocket wheel provided at the end of the bottle conveyor line will transfer the ampoule bottles and place them on the plastic boxes, and then the plastic boxes will be conveyed forward to the sealing unit for sealing, and then automatically boxed by the packaging unit to complete the automatic packaging operation of the ampoule bottles.

[0004] However, when the ampoule bottle is transferred from the transfer sprocket to the plastic box, there is a height difference when the ampoule bottle is transferred from the bottle conveyor line and then to the box conveyor line through the transfer sprocket. When the ampoule bottle hits an external object under the action of gravity, cracks may appear, and there may even be a risk of the bottle breaking. There are certain safety hazards that need to be improved. Summary of the invention

[0007] By adopting the above-mentioned technical scheme, 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 conveyor line, they can be conveyed by the bottle conveyor line to the workstation slot area located in the first loading area; then the rotating frame mechanism rotates, and can transfer each ampoule bottle to the second loading area. During this process, the possibility of collision between the ampoule bottles and external equipment is low, which is conducive to reducing the possibility of cracks or even breakage of the ampoule bottles, ensuring production safety. The plastic boxes containing the ampoule bottles are sorted one by one by the sorting device and placed on the box conveyor line. After the workstation slot area containing the ampoule bottles rotates to the second loading area, the box conveyor line transfers the plastic boxes to the workstation slot area, and then the rotating frame mechanism continues to rotate, transferring the plastic boxes to the film sealing device for film sealing, and finally transferring them to the unloading conveyor line, which can automatically complete a series of packaging processes such as labeling, boxing and film sealing of the ampoule bottles, and realize automated production.

[0008] Optionally, the rotating frame mechanism includes a central rotating drum and a plurality of outer plate frames evenly arranged on the outer circumference of the central rotating drum, and adjacent outer plate frames are arranged at intervals to form a station slot area; the width of the outer plate frame is smaller than the length of the ampoule bottle; The transfer device also includes two fixed side guard plates, which are respectively located on two opposite sides of the outer frame, and the distance between the two side guard plates is adapted to the length of the ampoule bottle; the end of the bottle conveyor line partially extends between the side guard plates and the outer frame.

[0009] By adopting the above-mentioned technical solution, two side guard plates are set and the distance between the two side guard plates is adapted to the length of the ampoule bottle, the possibility of the plastic box shifting sideways or falling can be reduced when the plastic box enters the work station slot area, thereby ensuring that the plastic box is smoothly transferred to the next work station when the outer plate frame rotates.

[0010] Optionally, the clamping mechanism includes a fixed column and a movable column, the fixed column is vertically fixed with a rotating shaft, and the fixed column is rotatably connected to the central rotating cylinder through the rotating shaft; The cross-section of the middle part of the rotating shaft is rectangular, the movable column is provided with a rectangular groove, the movable column is movably sleeved on the rotating shaft through the rectangular groove, and a hard spring is provided between the movable column and the rotating shaft, the hard spring is used to force the movable column to normally abut against the fixed column, so as to force the movable column and the fixed column to clamp the fixed plastic box together; The equipment assembly is provided with a fixed base, and the fixed base is provided with an operating mechanism. When the station slot area is located in the second loading area, the operating mechanism is located outside the clamping mechanism and is used to force the movable column to move in a direction away from the fixed column.

[0011] By adopting the above technical solution, when the station slot area is located in the second loading area, the clamping mechanism can be opened by controlling the operation of the operating mechanism to force the movable column to move away from the fixed column. At this time, the plastic box transported to the station slot area via the box conveyor line can enter between the movable column and the fixed column. Then, by forcing the operating mechanism to reset, the movable column can be reset to a state of contact with the fixed column under the elastic force of the hard spring, so that the movable column and the fixed column can clamp the plastic box together and maintain the clamping state, so that the plastic box can be smoothly brought to the next station when the outer plate frame rotates.

[0012] Optionally, the operating mechanism includes a first linear cylinder fixed to a fixed base and a push piece fixed to a movable end of the first linear cylinder. The movable column is partially provided with an inclined guide portion. When the first linear cylinder is actuated, the push piece abuts against the inclined guide portion and forces the movable column to move away from the fixed column.

[0013] By adopting the above-mentioned technical solution, when the first linear cylinder is actuated, the pushing piece at the movable end of the first linear cylinder can abut against the inclined guide portion of the movable column member, and then the cooperation between the inclined guide portion and the movable column member forces the movable column member to move in a direction away from the fixed column member, so that the clamping mechanism is in an open state.

[0014] Optionally, a holding plate is movably embedded in the inner side wall of the station slot area, the holding plate and the clamping mechanism are arranged on two opposite inner walls of the station slot area, and a side of the holding plate close to the clamping mechanism is provided with a plurality of sunken grooves, the sunken grooves are used for the ampoule bottle to be sunken and positioned; A structural groove for reducing weight is provided inside the outer plate frame, and an inserting column portion is provided on the side of the supporting plate away from the clamping mechanism. The inserting column portion is inserted into the structural groove, and an anti-slip portion is provided on the end of the inserting column portion away from the clamping mechanism. When the work station slot area where the supporting plate is located is located in the first loading area, the supporting plate is horizontally arranged, and at this time, the anti-slip portion is spaced apart from the inner wall of the structural groove on one side close to the work station slot area.

[0015] By adopting the above-mentioned technical solution, when the station slot area is located in the first loading area, the ampoule bottles transported to the station slot area via the bottle conveyor line can be transferred to the receiving plate, and the setting of each recessed groove on the receiving plate can play a role in positioning the ampoule bottles to a certain extent, so that each ampoule bottle is kept at a distance. It should be noted here that the subsequent plastic box is in an upside-down state when entering the station slot area, and then with the rotation of the outer plate frame, the plastic box and each ampoule bottle are flipped around the central axis of the outer plate frame, which can enable each ampoule bottle to smoothly enter each partition area of ​​the plastic box, and after the flipping of the receiving plate, it can naturally move downward under the action of its own gravity, which plays a role in pressing the bottle, which is conducive to pressing each ampoule bottle smoothly into each corresponding partition area of ​​the plastic box, so as to facilitate the subsequent film sealing operation.

[0016] Optionally, a plurality of arc guide plates are provided on the side of the side guard plate close to the other side guard plate, and adjacent arc guide plates are spaced apart from each other to form separation areas for separating ampoules; each arc guide plate is located between the first loading area and the second loading area, and when the work station slot area moves from the first loading area to the second loading area, each ampoule bottle enters each separation area respectively.

[0017] By adopting the above-mentioned technical solution, a plurality of arc-shaped guide plates are arranged to form a separation zone. When the outer plate frame rotates to drive the work station slot area to move from the first loading area to the second loading area, each ampoule bottle can move along the corresponding separation zone. This is beneficial to reduce the possibility of the ampoules overlapping each other in the second loading area, and ensure that the subsequent plastic boxes can smoothly enter the work station slot area of ​​the second loading area and be clamped and fixed by the clamping mechanism.

[0018] Optionally, a connecting rod is sleeved on the outer circumference of the rotating shaft, the connecting rod is located on the side of the fixed column away from the movable column, and the connecting rod is circumferentially linked with the rotating shaft; the end of the connecting rod is rotatably connected to a sliding rod, the end of the sliding rod is hinged with a sliding seat, the sliding seat is slidably connected to the central rotating cylinder, and when the station slot area rotates to the outside of the film sealing device, the sliding direction of the sliding seat is set in the same direction as the horizontal direction; A linkage groove is provided on the side of the sliding seat away from the central rotating cylinder, and a switching mechanism is fixed to the equipment assembly. When the station slot area moves to the outside of the film sealing device, the switching mechanism and the linkage groove cooperate with each other to switch the clamping mechanism from the station slot area to the film sealing device.

[0019] By adopting the above technical solution, when the outer plate frame 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, and then by controlling the action of the switching mechanism, the sliding seat and the sliding rod can be pulled away from the corresponding station slot area, so that the connecting rod rotates; in this process, since the connecting rod and the rotating shaft are circumferentially linked, the movement of the sliding seat can drive the rotating shaft to rotate, thereby forcing the clamping mechanism to smoothly bring the plastic box and the ampoule bottle to the film sealing device for film sealing. 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 sealed plastic box back to the station slot area, so that the outer plate frame can subsequently transfer the plastic box to the unloading conveyor line for the final packaging operation.

[0020] Optionally, the switching mechanism includes a second linear cylinder fixed to a fixed base and an arc-shaped pull plate fixed to a movable end of the second linear cylinder, and the linkage groove is arranged in an arc shape. When the workstation groove area moves to the outside of the film sealing device, the arc-shaped pull plate matches and enters the linkage groove.

[0021] By adopting the above-mentioned technical solution and setting an arc-shaped pull plate, when the work station slot area moves to the outside of the film sealing device, the arc-shaped pull plate can be matched and entered into the linkage slot. At this time, by controlling the movement of the second linear cylinder, the arc-shaped pull plate and the linkage slot can cooperate to make the sliding seat follow the movement of the second linear cylinder, thereby smoothly driving the clamping mechanism to switch between the work station slot area and the film sealing device.

[0022] Optionally, the equipment assembly fixed frame is provided with a bottle pressing roller, and the bottle pressing roller is located outside the film sealing device; when the clamping mechanism is switched from the work station slot area to the film sealing device, the ampoule bottle passes under the bottle pressing roller.

[0023] By adopting the above technical solution, when the clamping mechanism switches from the work 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 product rate.

[0024] Optionally, the feeding device includes a feeding platform for placing stacked plastic boxes, a limiting frame plate is provided on the side of the feeding platform close to the sorting device, and a reciprocating mechanism is provided on the side of the feeding platform away from the sorting device, for forcing the plastic boxes to move toward the limiting frame plate; The sorting device includes a third linear cylinder fixedly mounted on the loading 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 is actuated, the negative pressure suction nozzles enter the inner side of the limiting frame plate and suck the plastic box.

[0025] By adopting the above technical solution, stacked plastic boxes are placed on the loading platform, and the push mechanism can move the plastic boxes toward the limit frame to ensure that there are always plastic boxes at the limit frame. When the sorting device is in operation, the third linear cylinder can drive the mounting plate to move toward the limit frame, so that the negative pressure suction nozzle of the mounting plate fits the outermost plastic box; then the negative pressure suction nozzle is controlled to operate, and the negative pressure suction nozzle can absorb the outermost plastic box, and then the third linear cylinder resets, and the negative pressure suction nozzle brings the plastic box to the box conveyor line, and then the negative pressure suction nozzle is closed, and the plastic box can fall on the box conveyor line and be transported forward by the box conveyor line to the second loading area.

Each ampoule is transported from the bottle conveyor line to the workstation slot area, and then the rotating rack mechanism rotates to drive the ampoule to the second loading area. During this process, the possibility of collision between the ampoule and external equipment is low, which is conducive to reducing the possibility of cracks or even breakage of the ampoule, ensuring production safety; 2. By making the station slot 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, boxing and film sealing of ampoules can be automatically completed to realize automated production; 3. By setting up an operating mechanism to force the movable column to move away from the fixed column, the clamping mechanism located in the second loading area can be opened; then the plastic box enters between the movable column and the fixed column, and the movable column is reset under the elastic force of the hard spring, so that the movable column and the fixed column can clamp the plastic box together and maintain the clamping state, so that the plastic box can be smoothly brought to the next workstation when the outer panel frame rotates.

[0033] Back to Figure 2 The driving mechanism 42 includes a rotating motor 421 and a driving gear 422, wherein the rotating motor 421 is fixedly supported on the equipment assembly 1, and the driving gear 422 is fixed to the output end of the rotating motor 421; an integrally formed outer peripheral gear ring 413 is provided on one side end of the central rotating cylinder 411, and the outer peripheral gear ring 413 is coaxially arranged with the central rotating cylinder 411, and the outer peripheral gear ring 413 and the driving gear 422 are meshed with each other, and then when the rotating motor 421 is running, the meshing transmission of the driving gear 422 and the outer peripheral gear ring 413 can make the rotating frame mechanism 41 rotate circumferentially around the central axis of the central rotating cylinder 411, so that each station slot area 44 can pass through the bottle conveyor line 2, the box conveyor line 3, the film sealing device 5 and the unloading conveyor line 6 in sequence.

[0034] Each outer plate frame 412 is provided with a structural groove 414. The setting of the structural groove 414 can reduce the overall weight of the outer plate frame 412, so that the rotating motor 421 can smoothly drive the rotating frame mechanism 41 to rotate, thereby extending the service life of the driving motor. Each station slot area 44 is provided with an embedded groove on the inner wall, and a connecting groove connected to the structural groove 414 is provided on the inner bottom wall of the embedded groove. The cross-sectional shape of the connecting groove is rectangular; a supporting plate 45 is matched and installed in the embedded groove, and a plug-in column 451 is fixed on the side of the supporting plate 45. The plug-in column 451 is matched and inserted in the connecting groove and can move in the connecting groove; an anti-slip portion 452 is provided at one end of the plug-in column 451 away from the supporting plate 45. The anti-slip portion 452 is normally located in the structural groove 414, and the outer diameter of the anti-slip portion 452 is larger than the outer diameter of the plug-in column 451, which can prevent the supporting plate 45 from accidentally detaching from the embedded groove.

[0035] A plurality of recessed grooves 453 are provided on the side of the supporting plate 45 away from the plug-in column portion 451, and all the recessed grooves 453 are arranged side by side and equidistantly on the surface of the supporting plate 45; when the work station slot area 44 where the supporting plate 45 is located is located in the first loading area, the supporting plate 45 is horizontally arranged, and at this time the recessed grooves 453 can be located on the top surface of the supporting plate 45, for the ampoule bottle to be sunken and temporarily positioned; in addition, at this time, the anti-slip portion 452 is spaced apart from the inner wall of the side of the structural slot 414 close to the work station slot area 44.

[0036] Back to Figure 1 The bottle conveyor line 2 is arranged on the top of the equipment assembly 1 and is used to convey ampoules; the bottle conveyor line 2 includes a conveying platform 21 and two first conveyor belts 22 arranged on both sides of the conveying platform 21, and the conveying direction of the first conveyor belt 22 is the same as the extension direction of the conveying platform 21; a plurality of baffle bars 23 are equidistantly arranged on the surface of each first conveyor belt 22, and when the ampoule bottle is conveyed to the first conveyor belt 22 from the previous process, it can enter the area between two adjacent baffle bars 23, so that each ampoule bottle can be spaced and conveyed forward in sequence.

[0037] Reference Figure 3 It should be noted here that the end of each first conveyor belt 22 can extend to between a side guard plate 43 and an outer plate frame 412, so that the first conveyor belt 22 can smoothly convey the ampoule bottles to the interior of the work station slot area 44, and make each ampoule bottle respectively sink into each inner recessed groove 453 for preliminary positioning; the present application sets the end of the bottle conveyor line 2 as the first loading area.

[0038] Back to Figure 1 The bottle conveyor line 2 is also provided with a labeling device 24, which can automatically label the ampoule bottle, so that the label with the relevant information of the nalbuphine injection is automatically attached to the outer peripheral surface of the ampoule bottle. It should be noted here that the specific structure of the labeling device 24 in this embodiment is a conventional design in the art, which is not the focus of the present case, and therefore will not be described in detail here.

[0039] The box conveyor line 3 is fixedly mounted above the bottle conveyor line 2 and is used to convey plastic boxes. The front end of the box conveyor line 3 is provided with a loading device 31 for placing plastic boxes and a sorting device 32 for sorting plastic boxes, and the end of the box conveyor line 3 is set as a second loading area. Figure 4 The feeding device 31 includes a feeding platform 311, a limit frame plate 312 and a recursive mechanism. The feeding platform 311 is fixedly arranged on the top of the equipment assembly 1. When feeding, the operator can place the stacked plastic boxes flat on the feeding platform 311.

[0040] The recursive mechanism includes a linear module 313 fixed to the loading platform 311 and a pushing seat 314 arranged at the movable end of the linear module 313. When the linear module 313 is reset to the initial position, the pushing seat 314 can be located on one side of the loading platform 311 away from the box conveyor line 3; the limiting frame plate 312 is fixed to the top of the loading platform 311, and the limiting frame plate 312 is located on one side of the loading platform 311 close to the box conveyor line 3. The limiting frame plate 312 in this embodiment is U-shaped, and the internal width of the limiting frame plate 312 is slightly smaller than the width of the plastic box. When the linear module 313 is in motion, the pushing seat 314 can gradually push the plastic box to move toward 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, thereby playing a limiting role.

[0041] Reference Figure 5 The sorting device 32 includes a third linear cylinder 321 fixedly mounted above the loading platform 311 and a mounting plate 322 fixed to the movable end of the third linear cylinder 321, wherein the third linear cylinder 321 is in a normally retracted state, at which time the mounting plate 322 is located above the box conveyor line 3; a plurality of negative pressure suction nozzles 323 are fixed on the mounting plate 322, and when the third linear cylinder 321 is actuated, it can drive the mounting plate 322 to enter the inner side of the limiting frame plate 312 and make the negative pressure suction nozzle 323 abut against the plastic box closest to the limiting frame plate 312; then the negative pressure suction nozzle 323 operates and generates suction to absorb the plastic box, and the reset of the third linear cylinder 321 can make the plastic box pass through the limiting frame plate 312 and move to above the box conveyor line 3, and then the negative pressure suction nozzle 323 is closed, and the plastic box can fall on the box conveyor line 3 and be carried forward by the box conveyor line 3. It should be noted here that, in this embodiment, when the plastic box falls on the box conveying line 3, it will be in an upside-down state.

[0042] Reference Figure 6 When the rotating motor 421 drives the rotating frame mechanism 41 to rotate and the station slot area 44 enters the second loading area at the end of the box conveying line 3 from the first loading area at the end of the bottle conveying line 2, the plastic box can be conveyed to the station slot area 44 via the box conveying line 3. In addition, each station slot area 44 is provided with a clamping mechanism 7, which 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 conducive to the smooth transfer of the plastic box and each ampoule bottle to the next station; the clamping mechanism 7 and the object receiving plate 45 in a station slot area 44 can be respectively arranged on the two opposite inner walls of the station slot area 44.

[0043] Specific reference Figure 7The clamping mechanism 7 includes a fixed column 71 and a movable column 72. The fixed column 71 is vertically fixed with a rotating shaft 73, and a rotating seat 415 is provided on the side of the central rotating cylinder 411. By rotating the rotating shaft 73 and connecting it to the rotating seat 415, the fixed column 71 can be rotated to be connected to the central rotating cylinder 411. It should be noted here that the rotating shaft 73 line of the fixed column 71 will be perpendicular to the rotating shaft 73 line of the central rotating cylinder 411.

[0044] In this embodiment, the end surface of the middle part of the rotating shaft 73 is rectangular, and the movable column 72 is provided with a rectangular groove 721 penetrating on both sides. The movable column 72 can be movably sleeved on the rotating shaft 73 through the rectangular groove 721, so that the movable column 72 can only move along the axial direction of the rotating shaft 73, and the circumferential rotation of the movable column 72 around the rotating shaft 73 is limited. In addition, a hard spring 74 is sleeved on the outer peripheral side of the rotating shaft 73, and the hard spring 74 is located on the side of the movable column 72 away from the fixed column 71; one end of the hard spring 74 abuts against the movable column 72, and the other end abuts against the rotating seat 415, so that it can always generate elastic force acting on the movable column 72, thereby forcing the movable column 72 to normally abut against the fixed column 71.

[0045] In the initial state, the movable column 72 and the fixed column 71 are normally located inside the station slot area 44; a fixed base 11 is fixed on the top of the equipment assembly 1 (refer to Figure 1 ), the fixed base 11 is provided with an operating mechanism 12. When the work station slot area 44 moves to the second loading area, the operating mechanism 12 can be located outside the clamping mechanism 7. By controlling the operation of the operating mechanism 12, the movable column 72 can be forced to move away from the fixed column 71. At this time, the clamping mechanism 7 is in an open state, which is conducive to the plastic box entering the work station slot area 44 and being located between the fixed column 71 and the movable column 72, so that the clamping mechanism 7 can smoothly clamp the fixed plastic box.

[0046] Specifically, refer to Figure 7 The operating mechanism 12 includes a first linear cylinder 121 fixed to the fixed base 11 and a pushing piece 122 fixed to the movable end of the first linear cylinder 121. A side of the movable column 72 close to the pushing piece 122 is partially provided with an inclined guide portion 722, and the pushing piece 122 is arranged opposite to the inclined guide portion 722 along its own moving direction; when the first linear cylinder 121 is actuated, the pushing piece 122 can abut against the inclined guide portion 722, thereby forcing the movable column 72 to move away from the fixed column 71, so that the clamping mechanism 7 is in an open state; after the plastic box enters between the fixed column 71 and the movable column 72, the first linear cylinder 121 is controlled to reset, and after the pushing piece 122 is separated from the inclined guide portion 722, the movable column 72 is reset to abut against the fixed column 71 under the elastic force of the hard spring 74, so that the plastic box can be firmly clamped.

[0047] Also refer to Figure 8 It is worth mentioning that in this embodiment, each side guard plate 43 is provided with a plurality of arc guide plates 431 on the side close to the other side guard plate 43, and each arc guide plate 431 is integrally formed with the side guard plate 43; one end of each arc guide plate 431 in the arc direction is located in the first loading area, and the other end of the arc guide plate 431 in the arc direction extends to the second loading area, and adjacent side guard plates 43 are spaced from each other and form a separation zone. After each ampoule bottle enters the station slot area 44 located in the first loading area, each ampoule bottle is initially positioned in each sunken groove 453, and then during the rotation of the outer plate frame 412, each ampoule bottle can enter each separation zone, which can play a role of separation and guidance, reduce the possibility of ampoule bottles overlapping each other in the second loading area, and ensure that the plastic box can smoothly enter the station slot area 44 of the second loading area and be clamped and fixed by the clamping mechanism 7.

[0048] Back to Figure 1 The film sealing device 5 is arranged at a position opposite to the first feeding area, and is used to seal the open side of the plastic box; it should be noted that the specific structure of the film sealing device 5 is conventional in the art and is not the focus of the present case, so it will not be described in detail here. Figure 2 It should be noted that, when the outer plate frame 412 rotates to transfer the workstation slot area 44 from the second loading area to the film sealing device 5, the plastic box and each ampoule bottle flip over, so that each ampoule bottle falls into each partition area of ​​the plastic box. At the same time, during this process, the supporting 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-slip portion 452 abuts against the inner wall of the structural slot 414 and the supporting plate 45 is in the extreme position, the supporting plate 45 can just fit the plastic box.

[0049] Reference Fig. 9, a connecting rod 75 is sleeved on the outer circumference of the rotating shaft 73, and the connecting rod 75 is located on the side of the fixed column 71 away from the movable column 72; the connecting rod 75 is provided with a sleeve groove for the rotating shaft 73 to pass through, and the shape of the sleeve groove is a rectangle that matches the rotating shaft 73, thereby realizing the circumferential linkage setting of the connecting rod 75 and the rotating shaft 73, that is, when the connecting rod 75 rotates, it can drive the rotating shaft 73 to rotate together. In addition, the free end of the connecting rod 75 is rotatably connected to a sliding rod 76, and the end of the sliding rod 76 away from the connecting rod 75 is hinged with a sliding seat 77, and the sliding seat 77 is slidably connected to the side end surface of the central rotating cylinder 411, and when the station slot 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 of the sliding seat 77 away from the central rotating cylinder 411 . The linkage groove 771 is an arc-shaped groove, and the arc axis of the linkage groove 771 coincides with the center of the rotating shaft 73 of the central rotating cylinder 411 .

[0050] The equipment assembly 1 is provided with a switching mechanism 13, which 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, and the shape of the arc-shaped pull plate 132 is adapted to the shape of the linkage groove 771; when the turntable mechanism 41 moves with the work station slot area 44 to the outside of the film sealing device 5, the arc-shaped pull plate 132 can enter the linkage slot 771, and by controlling the movement of the second linear cylinder 131 to pull the sliding seat 77 to move toward 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, and then the clamping mechanism 7 is switched from the work station slot area 44 to the film sealing device 5, so as to facilitate the film sealing operation of the plastic box.

[0051] In this embodiment, the rotation angle of the clamping mechanism 7 is 90°, and after the clamping mechanism 7 rotates 90°, the side of the clamping mechanism 7 can abut against the side of the central rotating cylinder 411, thereby limiting the further rotation of the clamping mechanism 7. Figure 8 In addition, it should be noted that the side guard plate 43 close to the film sealing device 5 of the two side guard plates 43 is provided with an avoidance opening 432. When the work station slot area 44 moves to the outside of the film sealing device 5, the avoidance opening 432 can enable the clamping mechanism 7 to smoothly switch to the film sealing device 5 to perform the film sealing operation.

[0052] In addition, back to Figure 8 The equipment assembly 1 is fixedly provided with a rotatable bottle pressing roller 14, and the bottle pressing roller 14 is located outside the film sealing device 5; when the clamping mechanism 7 is switched from the work station slot area 44 to the film sealing device 5, each ampoule bottle can pass under the bottle pressing roller 14 in turn, and the setting of the bottle pressing roller 14 can further press the ampoule bottle completely into the separation area, which is convenient for the subsequent film sealing operation of the ampoule bottle.

[0053] Back to Figure 6The unloading conveyor line 6 is fixedly mounted on the top of the equipment assembly 1, and the unloading conveyor line 6 is located at the rear end of the film sealing device 5 along the moving direction of the work station slot area 44; the fixed base 11 is also provided with a reset column (not shown in the figure). When the plastic box to be completed with the film sealing operation enters the work station of the unloading conveyor line 6 along the work station slot area 44, the part of the movable column 72 protruding from the fixed column 71 can automatically abut against the reset column and switch the clamping mechanism 7 to the open state, which can be for a moment or for a period of time; based on this, the plastic box can automatically fall onto the unloading conveyor line 6 under its own gravity, and be transported forward by the unloading conveyor line 6 to enter the subsequent final packaging operation area.

[0054] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
