Description

Technical Field

[0001] This utility model belongs to the technical field of pharmaceutical production equipment, specifically relating to an aluminum-plastic blister pack guide plate structure. Background Technology

[0002] Aluminum-plastic blister packs, commonly known as "blister packaging" or "aluminum-plastic blister packs," are a widely used composite packaging form in the pharmaceutical packaging industry. The core structure consists of an upper layer of pharmaceutical-grade aluminum foil and a lower layer of rigid plastic sheet (mostly polyvinyl chloride (PVC) or polyvinylidene chloride (PVDC)) formed by thermoforming. The upper aluminum foil provides excellent barrier, light-blocking, and sealing properties, isolating oxygen, moisture, and light. The lower rigid plastic sheet is molded into independent "blister packs" to precisely contain solid medications such as tablets, capsules, and pills. The core function of this packaging is to provide an "independent, sealed space" for single-dose medications, preventing moisture, oxidation, contamination, or breakage during storage and transportation, ensuring stable efficacy. Clear labeling of the drug name, specifications, batch number, and expiration date facilitates dosage identification for patients and supports drug traceability management.

[0003] The guide plate is a key auxiliary component in aluminum-plastic blister packaging equipment (i.e., blister packaging machine). It is usually installed at the front end of the drug filling station and is mostly a metal or engineering plastic plate with specific guide grooves or channels. Its core function is "precise delivery and positioning of drugs": During the packaging process, the solid drugs to be packaged (such as tablets and capsules) enter the guide plate through the hopper. The guide plate, through its own channel structure, organizes the disordered drugs into an orderly arrangement and stably and accurately guides them into the recesses of the already formed plastic blister pack, avoiding drug jamming, misalignment, or incomplete filling. This directly ensures the filling accuracy and production efficiency of the aluminum-plastic blister pack and is a crucial step in ensuring that each blister pack can accurately accommodate a single dose of drug.

[0004] Existing guide plates use guide grooves on their surfaces to guide and transport medicines. However, after long-term use, the guide rack is prone to wear due to friction and collisions with the medicines, which affects the smoothness of the medicines' sliding. Furthermore, the fixed structure of the guide grooves can easily affect the smoothness of the medicines' sliding when transporting medicines with certain special shapes. Utility Model Content

[0005] The purpose of this utility model is to provide an aluminum-plastic blister pack guide plate structure, which aims to solve the problems of existing guide plates that use guide grooves on the surface to guide and transport medicines. However, after long-term use, the guide plate is prone to wear due to friction and collision of the medicines, which affects the smoothness of the medicine sliding. Furthermore, the fixed guide groove structure can easily affect the smoothness of the medicine sliding when transporting medicines with certain special shapes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aluminum-plastic blister pack guide plate structure, comprising a guide plate body, characterized in that: a slot is opened at the transverse end of the inner wall surface of the guide plate body, a plug is inserted into the surface of the slot, a separator is connected to the top surface of the plug, a stop is abutted to the surface of the separator, dovetail blocks are connected to the longitudinal end surfaces of both sides of the stop, the dovetail blocks are wedge-shaped connected to the dovetail groove, the dovetail groove is opened on the top surface of the mounting frame, the surface of the mounting frame is rotatably connected to one end surface of the guide plate body via a first rotating shaft, a first elongated oval groove is symmetrically opened on the longitudinal end surface of the mounting frame, and the other end surface of the guide plate body is rotatably connected to an adjustment frame via a second rotating shaft, a second elongated oval groove is opened on the surface of the adjustment frame.

[0007] As a preferred embodiment of the aluminum-plastic blister pack guide plate structure of this utility model, the slot is a "T"-shaped groove, the shape and size of which are adapted to the insert block.

[0008] As a preferred embodiment of the aluminum-plastic blister pack guide plate structure of this utility model, the separator is a U-shaped integrated structure with rectangular transparent observation windows installed on both sides of its longitudinal end.

[0009] As a preferred embodiment of the aluminum-plastic blister pack guide plate structure of this utility model, the guide plate body and the mounting frame are both U-shaped integrated structures, and the rectangular groove on the inner wall of the mounting frame is adapted to the shape and size of the outer wall of the guide plate body.

[0010] As a preferred embodiment of the aluminum-plastic blister pack guide plate structure of this utility model, the baffle is a U-shaped integrated structure, with a dovetail block connected to each of its two longitudinal end surfaces. The dovetail block is a trapezoidal structure, and its shape and size are adapted to the dovetail groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By using the slots on the guide plate body and the plugs connected to the bottom of the separator, the separator can be quickly fixed on the guide plate body. This allows the separator with the guide groove to be replaced according to the shape of the medicine to be transported. At the same time, the separator can be replaced regularly to avoid wear and tear on its surface caused by the medicine sliding during long-term use, which would affect the smoothness of medicine transport.

[0014] In addition, the two rotating shafts on both sides of the guide plate body and the elongated grooves on the mounting bracket and adjustment bracket facilitate quick fixing and adjustment of the angle of the guide plate body, thereby making it easy to fix the guide plate between the aluminum-plastic blister pack machine and the medicine conveyor belt, and making it easy to disassemble and maintain.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4This utility model provides the following technical solution: A guide plate structure for aluminum-plastic blister packs includes a guide plate body 1, a slot 2 is opened at the transverse end of the inner wall surface of the guide plate body 1, a plug block 3 is inserted into the surface of the slot 2, a separator 4 is connected to the top surface of the plug block 3, a baffle 5 is abutted to the surface of the separator 4, dovetail blocks 6 are connected to the longitudinal end surfaces of both sides of the baffle 5, the dovetail blocks 6 are wedge-shaped connected to the dovetail groove 7, the dovetail groove 7 is opened on the top surface of the mounting frame 8, the surface of the mounting frame 8 is rotatably connected to one end surface of the guide plate body 1 by a first rotating shaft 9, a first elongated groove 10 is symmetrically opened on the longitudinal end surface of the mounting frame 8, and the other end surface of the guide plate body 1 is rotatably connected to the adjusting frame 12 by a second rotating shaft 11, a second elongated groove 13 is opened on the surface of the adjusting frame 12.

[0023] Preferably, the slot 2 is a "T" shaped groove, the shape and size of which are adapted to the insert block 3.

[0024] In practical use, the insert 3 connected to the bottom of the separator 4 is inserted into the slot 2, and the insert 3 is inserted to the bottom of the slot 2. The above operation is repeated to fix the positions of the four sets of separators 4 on the inner wall of the guide plate body 1.

[0025] Preferably, the divider 4 is a U-shaped integrated structure with rectangular transparent observation windows installed on both sides of its longitudinal end.

[0026] In practical use, the width of the through groove on the surface of the separator 4 is 0.5-1mm larger than the maximum diameter of the target drug, and the depth is 1-2mm larger than the thickness of the drug, to ensure that the drug slides stably in a single row without lateral deviation. The through groove on the surface of the separator 4 facilitates the sliding and transfer of the tablets in the groove. At the same time, the observation window on the surface of the separator 4 can be used to observe the sliding of the drug in the through groove on the surface of the separator 4.

[0027] Preferably, both the guide plate body 1 and the mounting frame 8 are U-shaped integrated structures, and the rectangular groove on the inner wall of the mounting frame 8 is adapted to the shape and size of the outer wall of the guide plate body 1.

[0028] In practical use, the mounting bracket 8, which is rotatably connected to one side of the guide plate body 1 via the first rotating shaft 9, abuts against the bottom of the aluminum-plastic blister pack screening tray, thereby enabling the first elongated groove 10 on the surface of the mounting bracket 8 to cooperate with the fixing components and the mounting holes on the surface of the aluminum-plastic blister pack screening tray.

[0029] Preferably, the baffle 5 is a U-shaped integrated structure, with a dovetail block 6 connected to each of its two longitudinal end surfaces. The dovetail block 6 is a trapezoidal structure, and its shape and size are adapted to the dovetail groove 7.

[0030] In practical use, the dovetail blocks 6 on both sides of the baffle 5 are wedge-shaped and inserted into the dovetail groove 7, so that the baffle 5 can abut against the guide plate body 1 and the opening end of the slot 2 to fix the position of the insert block 3 inserted in the slot 2. The dovetail block 6 is a 45° isosceles trapezoidal structure, and the fit gap between the dovetail groove 7 and the dovetail block 6 is ≤0.1mm. The baffle 5 is fixed without loosening by wedge compression.

[0031] Preferably, the guide plate body 1, the mounting frame 8 and the first rotating shaft 9 form a rotary connection structure, and the guide plate body 1, the second rotating shaft 11 and the adjusting frame 12 form a rotary connection structure.

[0032] In practical use, the mounting bracket 8, which is rotatably connected to one side of the guide plate body 1 via the first rotating shaft 9, abuts against the bottom of the sieving plate of the aluminum-plastic blister pack machine. This allows the first elongated groove 10 on the surface of the mounting bracket 8 to cooperate with the fixing components and the mounting holes on the surface of the sieving plate of the aluminum-plastic blister pack machine to fix the connection between the mounting bracket 8 and the sieving plate of the aluminum-plastic blister pack machine. Then, the other side of the guide plate body 1 is rotatably connected to the second rotating shaft 11 to adjust the angle of the adjusting brackets 12 connected on both sides. This allows the second elongated groove 13 on the surface of the adjusting bracket 12 to abut against the mounting holes on the surface of the frame directly above the conveyor belt of the aluminum-plastic blister pack machine. Finally, bolts and other fixing components are used to connect the adjusting bracket 12 to the frame directly above the conveyor belt of the aluminum-plastic blister pack machine, thereby fixing the position of the guide plate body 1 on the aluminum-plastic blister pack machine.

[0033] Working principle: When packaging medicines using aluminum-plastic blister packs, the mounting bracket 8, rotatably connected to one side of the guide plate body 1 via the first rotating shaft 9, abuts against the bottom of the aluminum-plastic blister pack machine's screening tray. This allows the first elongated groove 10 on the surface of the mounting bracket 8 to engage with the fixing components and the mounting holes on the surface of the aluminum-plastic blister pack machine's screening tray, thus securing the connection between the mounting bracket 8 and the screening tray. Then, the other side of the guide plate body 1, via the rotatably connected second rotating shaft 11, adjusts the angle of the adjusting brackets 12 connected to both sides, allowing for... The second elongated groove 13 on the surface of the frame 12 abuts against the mounting hole on the surface of the frame directly above the conveyor belt of the aluminum-plastic blister pack machine body. Then, bolts and other fixing components are used to connect the adjusting frame 12 and the frame directly above the conveyor belt of the aluminum-plastic blister pack machine body, thereby fixing the position of the guide plate body 1 on the aluminum-plastic blister pack machine body. The tilt angle of the guide plate body 1 can be adjusted within the range of 15°-30° by the rotational cooperation of the mounting frame 8 and the adjusting frame 12. This range is the optimal angle for the gravity sliding of the medicine, which avoids jamming and prevents the medicine from deviating from the mold due to excessive speed.

[0034] At this point, depending on the shape and size of the tablets or capsules to be processed, select a partition frame 4 with an appropriate through slot size. Insert the insert block 3 connected to the bottom of the partition frame 4 into the slot 2 and insert the insert block 3 into the bottom of the slot 2. Repeat the above operation to fix the position of the four sets of partition frames 4 on the inner wall of the guide plate body 1. Then, use the dovetail blocks 6 on both sides of the baffle 5 to wedge into the dovetail groove 7, so that the baffle 5 can abut against the opening end of the guide plate body 1 and the slot 2 to fix the position of the insert block 3 inserted into the slot 2. At the same time, when the food-grade silicone rubber baffle 5 abuts against the intersection of the guide plate body 1 and the insert block 3, it can elastically fill the gap at the intersection of the guide plate body 1 and the mounting frame 8 with the angle adjusted, so as to avoid the gap between the two and affect the smoothness of the subsequent sliding of the medicine.

[0035] After the fixing is completed, the tablets screened from the screening plate of the aluminum-plastic blister pack machine body fall into the through groove opened on the surface of the separator 4. Then, through the action of the inclined guide plate body 1, the medicine is precisely connected to the medicine mold groove above the conveyor belt of the aluminum-plastic blister pack machine body on the other side and falls into it, thereby guiding and transporting the medicine that needs to be packaged.

[0036] The guide plate body 1 is made of food-grade 304 stainless steel (or high-hardness food-grade PPS plastic), and the surface is polished (roughness Ra≤0.8μm), which not only meets the safety standards for drug contact, but also reduces the frictional resistance when the drug slides.

[0037] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
