Description

Technical Field

[0001] The utility model relates to the field of oral solid capsule production, and specifically relates to a capsule feeding device and a blister machine. Background Art

[0002] A blister machine is a device for hermetically packaging products with plastic films, applicable to processing thermoformed films, aluminum formed films, and aluminum cover films to more easily fit the surface of articles, form on a forming die, blow the softened film into blisters using compressed air, precisely place the products into the blister eyes of a blister plate by a filling device, seal the covering film and the forming film at a suitable temperature and pressure, simultaneously print the batch number through a typing and embossing device, and finally cut the products into packaged plates of specified sizes through a punching device.

[0003] In order to prevent materials from blocking when entering the filling plate, the rotary brush can rotate clockwise to prevent excess materials from blocking at the interface of the device. However, the material of the rotary brush is relatively hard, and for relatively sensitive capsules, the capsules will be repeatedly rubbed in the device, easily grinding the capsules. Moreover, each brush of the existing rotary brush is a complete rectangle. When the amount of capsules is large, it is easy to block between each brush of the rotary brush, resulting in extrusion and causing the capsules to deform, affecting the appearance of the capsules and reducing the qualified rate of blister packaging.

[0004] In addition, for relatively large-sized capsules, it is difficult to control the device angle during the filling and guiding process to enable the capsules to enter the blister eyes intact and smoothly. Sometimes, due to the greater weight of the capsule products, the angle between the feeding devices is not gentle enough, and under the influence of gravity, a strong impact force is received at the moment of entering the blister eyes, resulting in deformation of the capsules at least and rupture at worst, affecting the appearance and quality of the capsules.

[0034] Figure 1 is a schematic structural diagram of an embodiment of a capsule feeding device of the present utility model; Figure 2 is Figure 1 a side view of the capsule feeding device; Figure 3 is a schematic diagram of a formed blister.

[0035] Capsules on the market can generally be divided into models and sizes of No. 000, No. 00, No. 0, No. 1, No. 2, No. 3, No. 4, No. 5 and other special specifications according to their capacity. The capsule sizes from No. 000 to No. 5 decrease in sequence, and No. 000 is the largest. No. 0 is a commonly used model, and the size can be referred to as that of cold medicine, and No. 1 can be referred to as that of amoxicillin. Conventional extended capsules are indicated by the suffix "el", such as 00el. Special specification models can be formulated by the production enterprise itself according to its own enterprise standards.

[0036] From Figures 1 to 2 As can be seen, the capsule feeding device may include a material distribution plate 1, a filling plate 3, an auxiliary brush 2, a feeding extender 4, and a guiding platform 5.

[0037] The top surface of the filling plate 3 is connected to the bottom surface of the material distribution plate 1. The auxiliary brush 2 may include a motor and a roller 21. A plurality of comb teeth 22 are arranged radially on the outer peripheral surface of the roller 21. The roller 21 is arranged above the material distribution plate 1 through a support structure 6, so that the roller 21 can transfer the falling capsules to the filling plate 3 under the drive of the motor, prevent the capsules from being blocked at the junction of the material distribution plate 1 and the filling plate 3, and play a buffering role.

[0038] In an alternative embodiment, the motor may be arranged inside or outside the roller 21. If the motor is arranged outside the roller 21, one end of the support structure 6 may be fixed to the adjacent motor, and the other end is fixed to the roller 21 so that it extends above the material distribution plate 1. The support structure 6 may be arranged on the material distribution plate 1 or the filling plate 3. In actual operation, those skilled in the art can arrange the positions of the support structure 6 and the motor according to the specific situation and working environment. In Figure 1 and Figure 2 the illustrated embodiment, the situation where the support structure 6 is arranged on the material distribution plate 1 and the embodiment where the motor drives inside the roller 21 are shown.

[0039] In this embodiment, the feeding extender 4 is located between the filling plate 3 and the guiding platform 5, and both ends can be detachably connected to the lower end of the filling plate 3 and the guiding platform 5 through connectors respectively. Specifically, as Figure 1 shown, the upper end of the feeding extender 4 is detachably connected to the lower end of the filling plate 3 through a first connector 7, and the lower end of the feeding extender 4 is detachably connected to the guiding platform 5 through a second connector 8.

[0040] It should be noted that the detachable connection is a detachable movable connection, and the movable connection means that the angles formed by the upper and lower ends of the feeding extender 4 connected to the filling plate 3 and the guiding platform 5 respectively can be independently adjusted. Optionally, the adjustment range of the angle formed by the upper end of the feeding extender 4 connected to the lower end of the filling plate 3 is 0 to 90°; the adjustment range of the angle formed by the lower end of the feeding extender 4 connected to the upper end of the guiding platform 5 is 0 to 90°. It should be noted that in this embodiment, the "upper end" of the feeding extender 4 refers to Figure 1 the end with a higher slope near the filling plate 3, and the "lower end" refers to the end with a lower slope near the guiding platform 5.

[0041] In an alternative embodiment, the feeding extender 4 may be in a straight slope shape or a concave arc slope shape. In such as Figure 2In the illustrated embodiment, the blanking extender 4 shown in the figure is in the shape of a concave arc slope.

[0042] Figures 1 to 2 The capsule blanking device shown also includes a series of guide rails 11, conveying troughs, channels or guide posts, which can guide the capsules to move along a predetermined path, thereby avoiding collisions or overturning of the capsules during the blanking process and ensuring that the arrangement directions of the capsules are consistent. Specifically, the filling plate 3 has a number of first capsule conveying troughs 31; the blanking extender 4 has a number of third capsule conveying troughs 41; the guiding platform 5 has a number of second capsule conveying troughs 51. Among them, the first capsule conveying trough 31 is aligned with the second capsule conveying trough 51, the first capsule conveying trough 31 is aligned with the third capsule conveying trough 41; the third capsule conveying trough 41 is aligned with the second capsule conveying trough 51.

[0043] The dividing plate 1 is mainly used to evenly distribute the capsules into different guide rail 11 paths, and the filling plate 3 is connected to the lower end of the dividing plate 1 for discharging to fill the capsules into the bubble eyes of the formed blister. As Figure 3 shown, the formed blister is a container with a series of grooved bubble eyes formed by blow molding a softened film with compressed air, and is used to place the capsules.

[0044] In order to avoid the capsules being worn out by repeated friction in the auxiliary brush 2, in this embodiment, the material of the roller 21 is pharmaceutical butyl rubber, which has good elasticity and softness. In addition, the roller 21 made of pharmaceutical butyl rubber can withstand a large amount of impact and friction during high-speed rotation and has good wear resistance.

[0045] In alternative other embodiments, the material of the roller 21 can be a soft rubber material with a hardness value range between 30 and 50 Shore A. However, it should be noted that since the roller 21 of the auxiliary brush 2 is used for pharmaceutical production, pharmaceutical-grade materials should still be selected and comply with the "Measures for the Administration of Pharmaceutical Packaging Materials and Containers" promulgated by the Order of the State Drug Administration.

[0046] When using small-sized capsules, there is no need to additionally install the blanking extender 4, but when using size 00 and larger-sized capsules, it is necessary to install the blanking extender 4 to play a buffering role and avoid appearance defects caused by the impact force on the capsules.

[0047] The guiding platform 5 is located at the most downstream of the entire capsule feeding device and is used to guide the capsules to smoothly and precisely slide into the blister eyes of the formed blister pack along a preset path. A blister eye refers to a special structure formed by a blister packing machine during the packaging process for containing medicines or other small items. The blister eyes are made by heating and softening a plastic sheet (usually materials such as polyvinyl chloride PVC or polyvinylidene chloride PVDC), and then using the method of vacuum thermoforming or compressed air blow molding to form a specific groove shape in a mold. Subsequently, medicines or other items are placed in these grooves, and then a covering material (such as aluminum foil) is sealed with the plastic sheet through a sealing mechanism to form a sealed packaging unit.

[0048] When the capsules are arranged in an orderly manner on the filling plate 3 after passing through the auxiliary brush 2, adjusting the angle between the feeding extender 4 and the filling plate 3 and the guiding platform 5 to be gentler can prevent the capsules from being impacted strongly when discharging from the filling plate 3, thus avoiding appearance defects. After a certain buffering effect on the feeding extender 4, the capsules are then transported to the guiding platform 5, effectively improving the product qualification rate and ensuring product quality. It should be noted that the basis for judging "gentler" is whether the capsules can be fed smoothly without blockage and jumping intervals, and specifically, it can be adjusted according to the model size of the capsules.

[0049] Figure 4 is Figure 1 the schematic structural view of the auxiliary brush in Figure 5 is Figure 4 the top view of the auxiliary brush; Figure 6 is Figure 4 the side view of the auxiliary brush.

[0050] As can be seen from Figures 4 to 6 the auxiliary brush 2 includes a drum 21 and a number of comb teeth 22 arranged radially on the outer periphery of the drum 21, rather than a complete integral rectangular sheet brush. In an alternative embodiment, the comb teeth 22 on the outer peripheral surface of the drum 21 are arranged in several rows, and the comb teeth 22 on two adjacent rows are Figures 4 to 6 aligned in a staggered manner as shown in Figures 1 to 2 shown, and the filling plate 3 Figures 1 to 2At the junction shown), it can also provide a buffer space during the clockwise rotation of the auxiliary brush 2, avoiding the blockage between the comb teeth 22 of the brush due to a large amount of capsules, resulting in mutual extrusion and causing deformation of the capsules, which may lead to appearance defects. Specifically, the discrete distribution of the comb teeth 22 with a certain spacing and angle can control the feeding speed of the capsules, buffer the direct impact during the feeding of the capsules to cause deformation and damage, and the comb teeth 22 continuously rotating with the drum 21 can also prevent the material from being blocked during the feeding process and maintain the continuous movement of the capsules. The misaligned and aligned comb teeth 22 can also make the capsules at any position, such as the capsules in the corner, move together, reducing the waste of materials.

[0051] In summary, for the capsule feeding device provided by the present utility model, the capsule material enters the filling plate 3 through the material distribution plate 1. To prevent the capsule material from being blocked when entering the filling plate 3, the auxiliary brush 2 can rotate clockwise at a high speed to prevent the excess capsule material from blocking the connection between the material distribution plate 1 and the filling plate 3. When using large-sized, large-capacity, and relatively fragile capsules for packaging, the auxiliary brush 2 made of medicinal butyl rubber of the present utility model can not only prevent the excess capsule material from blocking the interface between the material distribution plate 1 and the filling plate 3, but also provide a buffer space to avoid extrusion caused by the large amount of capsules occupying space, effectively improving the qualified rate of the product and ensuring the product quality.

[0052] When the capsules are arranged orderly on the filling plate 3 after passing through the auxiliary brush 2, for No. 0 and smaller capsules, there is no need to install the feeding extender 4. During the initial production, only the angle between the filling plate 3 and the guiding platform 5 can be adjusted according to the situation of the capsule material to achieve smoother sliding of the capsule material into the forming packaging material, that is, the "bubble eye" mentioned above. However, for No. 00 and larger-sized capsules, the feeding extender 4 is installed, with its upper end connected to the filling plate 3 and its lower end connected to the guiding platform 5. It should be noted that the angle between the filling plate 3 and the feeding extender 4 also needs to be gentle, and at the same time, it is necessary to ensure that the angle between the feeding extender 4 and the guiding platform 5 is also gentle, so that the capsules can avoid strong impact when discharging from the filling plate 3, which may cause appearance defects. After a certain buffering effect through the feeding extender 4, the capsules are then transported to the guiding platform 5, effectively improving the qualified rate of the product and ensuring the product quality.

[0053] To achieve the foregoing purpose, the present utility model also provides a capsule blister machine, wherein the capsule blister machine includes the capsule feeding device described in any of the foregoing embodiments.

[0054] The preferred specific embodiments of the present utility model have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present utility model without creative work. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field based on the concept of the present utility model through logical analysis, reasoning, or limited experiments on the basis of the prior art shall fall within the protection scope determined by the claims.
