Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging technology, specifically a pressing device for a calcium gluconate tablet packaging line. Background Technology
[0002] In the packaging and production of tablets such as calcium gluconate tablets, blister packaging is commonly used. This process usually includes: heating and molding a rigid plastic sheet to form a cavity, filling the cavity with a tablet, covering it with aluminum foil, and finally heating and pressurizing the aluminum foil and blister pack to seal it. Existing pressing devices mostly employ flat plate pressing or simple roller pressing. In practical applications, these traditional methods have significant drawbacks: due to the raised cavities at the bottom of the blister pack, when it enters the pressing station, the cavities fall into the grooves of the conveyor plate, leaving the blister pack surface (the annular plane that needs to be sealed with the aluminum foil) suspended in this area. Traditional flat or smooth rollers cannot apply effective pressure to this suspended area, resulting in an incomplete and loose seal between the aluminum foil and the blister pack around the cavities. This easily leads to air leakage or insufficient sealing strength, severely affecting the product's shelf life and quality. Utility Model Content
[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a pressing device for a calcium gluconate tablet packaging line, which solves the aforementioned problems.
[0004] (II) Technical Solution To achieve the above objectives, this utility model is implemented through the following technical solution: a pressing device for a calcium gluconate tablet packaging line, comprising a conveying plate, a hot press roller, a rotating shaft, and a support wheel assembly. The hot press roller and the rotating shaft are respectively disposed on the upper and lower sides of the conveying plate. The support wheel assembly is equidistantly installed on the outer side of the rotating shaft. The conveying plate is used to support and convey the blister pack, and the hot press roller is used to press the blister pack and aluminum foil together. The support wheel assembly includes a support wheel, a groove, a fixing ring, and a fixing bolt. The outer wall of the support wheel has a groove, and the side of the support wheel has a fixing ring. The support wheel and the fixing ring are integrally formed. The middle of both the support wheel and the fixing ring is penetrated by a rotating shaft, and the fixing ring is locked to the rotating shaft by the fixing bolt.
[0005] Preferably, a drive gear is installed on both the left and right sides of the outer wall of the rotating shaft, and the rotating shaft is connected to the drive gear in a driving connection. The top of the drive gear meshes with the driven gear, and the driven gear is connected to the hot press roller in a driving connection through a connecting shaft. The rotating shaft is connected to the output shaft of the motor in a driving connection.
[0006] Preferably, the conveyor plate includes strip plates, strip grooves, a support plate, and conveyor wheels.

[0014] 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.
[0015] Please see Figure 1-5 This utility model provides a pressing device for a calcium gluconate tablet packaging line: it includes a conveyor plate 1, a hot press roller 2, a rotating shaft 3, and a support wheel assembly 4. The hot press roller 2 and the rotating shaft 3 are respectively arranged on the upper and lower sides of the conveyor plate 1. The support wheel assembly 4 is installed at equal intervals on the outer side of the rotating shaft 3. The conveyor plate 1 is used to support and convey the blister pack 11, and the hot press roller 2 is used to press the blister pack 11 and the aluminum foil 13. The support wheel assembly 4 includes a support wheel 41, a groove 42, a fixing ring 43, and a fixing bolt 44. The outer wall of the support wheel 41 is provided with a groove 42, and a fixing ring 43 is provided on the side of the support wheel 41. The support wheel 41 and the fixing ring 43 are integrally formed. The middle of the support wheel 41 and the fixing ring 43 are both penetrated by the rotating shaft 3, and the fixing ring 43 is locked to the rotating shaft 3 by the fixing bolt 44. The rotating shaft 3 has drive gears 8 installed on both the left and right sides of its outer wall, and the rotating shaft 3 is connected to the drive gears 8 in a transmission manner. The top of the drive gear 8 meshes with the driven gear 9, and the driven gear 9 is connected to the hot press roller 2 in a transmission manner through the connecting shaft 10. The rotating shaft 3 is connected to the output shaft of the motor 5 in a transmission manner. The conveyor plate 1 includes a strip plate 101, a strip groove 102, a support plate 103 and a conveyor wheel 104. The strip plates 101 are fixed at equal intervals on the support plate 103, and the strip groove 102 is formed between the strip plates 101. The conveyor wheel 104 is provided on the top of the strip plate 101 located at the edge. The conveyor wheel 104 is equipped with a drive motor. The bottom of the blister pack 11 is supported by the strip plate 101. The movement of the blister pack 11 is achieved by the unwinding of the blister pack roll and the rotation of the conveyor wheel 104 to achieve stable conveying of the blister pack 11. After the blister pack 11 is pressed out of the medicine cavity 12 by the film press, the medicine cavity 12 slides in the strip groove 102. The hot press roller 2 and the rotating shaft 3 are respectively installed in the upper shell 6 and the lower shell 7. The upper shell 6 and the lower shell 7 are respectively located on the upper and lower sides of the conveyor plate 1, and the left and right sides of the upper shell 6 and the lower shell 7 are fixedly connected by bolts. The number and spacing of the support wheel assemblies 4 are the same as the number and spacing of the strip grooves 102. The outer diameter of the support wheel 41 is larger than that of the fixing ring 43, and the top of the support wheel 41 is embedded in the strip groove 102 of the conveying plate 1. The outer wall of the rotating shaft 3 is provided with bolt holes at equal intervals corresponding to the fixing ring 43. The spacing and installation angle of the support wheels 41 are limited in advance by opening the bolt holes.
[0016] Please see the appendix Figure 6 The pressing device of this utility model is set in a complete packaging line. Its upstream is connected to the molding equipment and filling equipment in the prior art, and its downstream is connected to the film covering equipment in the prior art. When packaging calcium gluconate tablets, the blister pack 11 is first pressed into the filling cavity 12 by the molding equipment, and then smoothly conveyed on the conveyor plate 1. During the conveying process, the filling equipment accurately drops the calcium gluconate tablets 14 into the filling cavity 12 of the blister pack 11, and covers them with aluminum foil 13 after filling. When the blister pack 11 and the aluminum foil 13 pass through the hot press roller 2 and the support wheel assembly 4 together, the part of the bottom of the blister pack 11 located on the strip groove 102 is supported by the support wheel 41 embedded in the strip groove 102. At the same time, the support wheel 41 rotates continuously, and the groove 42 set on its outer wall can effectively avoid the bottom of the filling cavity 12 being pressured, thereby ensuring the integrity of the medicine and the packaging quality.
[0017] Implementation principle: When the packaging line is running, the blister pack 11, which has been formed (i.e., has medicine holes 12), contains calcium gluconate tablets 14, and is covered with aluminum foil 13, is conveyed forward on the conveyor plate 1; when the blister pack 11 runs to the pressing station between the hot press roller 2 and the support wheel assembly 4, the pressing device of this application starts to work: The hot press roller 2 located above the conveyor plate 1 rotates under the drive mechanism (a transmission system consisting of a motor 5 via a rotating shaft 3, a drive gear 8, a driven gear 9, and a connecting shaft 10), applying downward heat and pressure to the aluminum foil 13 on the surface of the blister pack 11. At the same time, the rotating shaft 3 located below the conveyor plate 1 drives multiple support wheel assemblies 4, which are equidistantly installed on its outer side, to rotate synchronously. The top of each support roller 41 is precisely embedded in the strip groove 102 of the conveyor plate 1 and supports the blister pack 11 from below. The groove 42 on its outer wall provides clearance space for the medicine cavity 12 at the bottom of the blister pack 11. Therefore, when the hot press roller 2 presses down, the pressure is mainly applied to the flat area of the blister pack 11 and the aluminum foil 13, while the bottom of the medicine cavity 12 containing the tablets is suspended in the groove of the support roller 41, avoiding direct pressure. This design ensures that the aluminum foil 13 and the blister pack 11 are tightly heat-sealed, while effectively preventing the calcium gluconate tablets 14 in the medicine cavity 12 from breaking due to pressure, thus ensuring the integrity of the packaging and the quality of the medicine.
