Description

Technical Field

[0001] This utility model relates to the field of packaging substrate drying technology, specifically a substrate dryer for pharmaceutical packaging. Background Technology

[0002] In recent years, the pharmaceutical industry has developed rapidly. As an important part of the pharmaceutical field, drug packaging refers to the operation of dispensing, sealing, filling, and labeling semi-finished or finished drug preparations using appropriate materials or containers and packaging technology to provide quality assurance for drugs. Therefore, the quality of drug packaging also greatly affects the quality of drugs. With people paying more and more attention to drug quality, how to improve the quality of drug packaging has become a research focus for major drug packaging manufacturers.

[0003] For example, a pharmaceutical packaging substrate dryer (publication number: CN220472182U) includes a drying chamber with an inlet and an outlet at both ends. A first conveyor and a second conveyor are installed inside the inlet and outlet, respectively, and conveyor belts are installed on both the first and second conveyors. A turning roller is rotatably connected between the two sides of the inner cavity of the drying chamber via a connecting shaft. This invention, through the arrangement of a drying chamber, inlet, outlet, first conveyor, second conveyor, conveyor belt, turning roller, storage tank, and drive motor, uses the first conveyor and conveyor belt to place the pharmaceutical substrate to be dried in the drying chamber, drying one side of the substrate. Then, the drive motor drives the turning roller to rotate, cooperating with the storage tank to turn the pharmaceutical substrate onto the conveyor belt of the second conveyor, thereby turning, drying, and conveying the pharmaceutical substrate, thus improving the drying effect and efficiency of the pharmaceutical substrate.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, it was discovered that the aforementioned equipment lacks a dehumidification mechanism during application. Water vapor generated during the drying process of the packaging substrate inside the drying chamber will accumulate at the top of the drying chamber and cannot be discharged, resulting in a continuous increase in humidity, which in turn affects the drying of the packaging substrate. Therefore, we need to propose a substrate dryer for pharmaceutical packaging. Utility Model Content

[0005] The purpose of this invention is to provide a substrate dryer for pharmaceutical packaging. By using a steam extraction fan, the water vapor generated during the drying process of the packaging substrate can be extracted and discharged, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A substrate dryer for pharmaceutical packaging includes a drying chamber. A feeding hopper is fixedly connected to the top of one end of the drying chamber. Two sets of conveying mechanisms for conveying the substrate are installed vertically below the feeding hopper in the drying chamber. Two sets of drying mechanisms for drying the substrate are installed at the top and bottom of the inner side of the drying chamber. A steam suction fan is installed above one end of the drying chamber. A turning mechanism for turning the substrate is provided on one side of the steam suction fan. A discharge plate is provided at the bottom of the other end of the drying chamber.

[0008] Preferably, the conveying mechanism includes several sets of rotating rollers, which are equidistantly mounted on the inner walls of both sides of the drying chamber. One end of one set of rotating rollers passes through the drying chamber and is fixedly connected to a drive motor. The outer walls of the several sets of rotating rollers are provided with a mesh conveyor belt.

[0009] Preferably, the discharge end of one set of conveying mechanisms is located above the feed end of another set of conveying mechanisms, and the discharge end of the other set of conveying mechanisms is located above the discharge plate.

[0010] Preferably, the drying mechanism includes two sets of mounting brackets, which are symmetrically fixedly installed on the inner wall of the drying chamber. Several sets of heating tubes are fixedly installed between the two sets of mounting brackets, and a heat dissipation shell with several sets of through holes on its surface is fixedly installed on the outside of the several sets of heating tubes in the drying chamber.

[0011] Preferably, the material turning mechanism includes a rotating shaft, which is rotatably mounted on the inner wall of the drying chamber, and one end of the rotating shaft passes through the drying chamber and is fixedly connected to a material turning motor. Three sets of material turning plates are installed in a circular array on the outer wall of the rotating shaft.

[0012] Preferably, the interior of the drying chamber is fixedly installed with a guide plate at an angle, and the guide plate is located on one side of the turning mechanism.

[0013] Preferably, two sets of steam suction fans are symmetrically arranged, and a discharge port is opened at the bottom of one end of the drying box, with the discharge plate inclinedly arranged inside the discharge port.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through the setting of two sets of steam suction fans, can suck out the water vapor generated during the drying process of the packaging substrate in the drying box, avoid the accumulation of water vapor in the drying box, and thus maintain a dry environment in the drying box. This helps to speed up the drying process and improve the drying efficiency.

[0016] 2. By using two sets of conveying mechanisms in conjunction with a turning mechanism, the three sets of turning plates in the turning mechanism cause the packaging substrate to fall from one set of mesh conveyor belts into another set of mesh conveyor belts, thus turning it over. At the same time, when the mesh conveyor belts are conveying the packaging substrates, they will not obstruct the hot air output by the drying mechanism at the bottom of the drying chamber. They can also dry the side of the packaging substrate that is in contact with the mesh conveyor belt. This has the advantages of improving drying uniformity, enhancing drying efficiency, reducing drying time, avoiding the conveyor belt from obstructing drying, adapting to various substrates, and reducing energy consumption.

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-5 This utility model provides a technical solution:

[0025] A substrate dryer for pharmaceutical packaging includes a drying chamber 1. A feeding hopper 2 is fixedly connected to the top of one end of the drying chamber 1. Two sets of conveying mechanisms 3 for conveying the substrate are installed in the drying chamber 1 below the feeding hopper 2 in a vertically corresponding manner. Two sets of drying mechanisms 4 for drying the substrate are installed at the top and bottom of the inner side of the drying chamber 1. A steam suction fan 6 is installed above one end of the drying chamber 1. A turning mechanism 5 for turning the substrate is provided on one side of the steam suction fan 6. A discharge plate 8 is provided at the bottom of the other end of the drying chamber 1.

[0026] Furthermore, the conveying mechanism 3 includes several sets of rotating rollers 31, which are equidistantly mounted on the inner walls of both sides of the drying chamber 1. One end of one set of rotating rollers 31 passes through the drying chamber 1 and is fixedly connected to a drive motor 32. The outer walls of the several sets of rotating rollers 31 are provided with a mesh conveyor belt 33, which facilitates the rotation of the connected rotating rollers 31 by the drive motor 32, so that the several sets of rotating rollers 31 cooperate with the mesh conveyor belt 33 to convey the packaging substrate.

[0027] Specifically, the discharge end of one set of conveying mechanisms 3 is located above the inlet end of another set of conveying mechanisms 3, and the discharge end of the other set of conveying mechanisms 3 is located above the discharge plate 8, so that the packaging substrate can fall from one set of mesh conveyor belts 33 onto another set of mesh conveyor belts 33.

[0028] Furthermore, the drying mechanism 4 includes two sets of mounting brackets 41, which are symmetrically fixedly installed on the inner wall of the drying chamber 1. Several sets of heating tubes 42 are fixedly installed between the two sets of mounting brackets 41. A heat dissipation shell 43 with several through holes on its surface is fixedly installed on the outside of the several sets of heating tubes 42 in the drying chamber 1, so as to facilitate the heating of the air inside the drying chamber 1 by starting through the several sets of heating tubes 42. The heat dissipation shell 43 protects the heating tubes 42 while dissipating the heat evenly.

[0029] Furthermore, the turning mechanism 5 includes a rotating shaft 51, which is rotatably mounted on the inner wall of the drying chamber 1. One end of the rotating shaft 51 passes through the drying chamber 1 and is fixedly connected to a turning motor 52. Three sets of turning plates 53 are installed in a ring array on the outer wall of the rotating shaft 51, so that the packaging substrate can be turned over when it falls from one set of mesh conveyor belts 33 into another set of mesh conveyor belts 33 by the rotation of the three sets of turning plates 53 on the outer wall of the rotating shaft 51 driven by the turning motor 52.

[0030] Furthermore, a guide plate 9 is fixedly installed at an angle inside the drying chamber 1. The guide plate 9 is located on one side of the turning mechanism 5, which facilitates the protection and shielding of the packaging substrate turned by the turning plate 53, preventing some of the packaging substrate from falling into the gap between the mesh conveyor belt 33 and the inner wall of the drying chamber 1.

[0031] Furthermore, two sets of steam suction fans 6 are symmetrically arranged. The steam suction fans 6 suck out the water vapor generated during the drying process of the packaging substrate in the drying box 1 to prevent water vapor from accumulating in the drying box 1. A discharge port 7 is opened at the bottom of one end of the drying box 1, and the discharge plate 8 is inclinedly arranged inside the discharge port 7.

[0032] Working Principle: In use, the packaging substrate is fed into the drying chamber 1 through the feeding hopper 2, allowing it to fall onto the mesh conveyor belt 33 in the upper conveying mechanism 3. The packaging substrate is dried by the cooperation of four drying mechanisms 4 at the top and bottom of the drying chamber 1. Two conveying mechanisms 3 work in conjunction with a turning mechanism 5, where three turning plates 53 rotate to turn the packaging substrate from one mesh conveyor belt 33 to another. Simultaneously, the mesh conveyor belt 33 does not obstruct the hot air output from the drying mechanism 4 at the bottom of the drying chamber 1 while drying the side of the packaging substrate in contact with the mesh conveyor belt 33. Two steam suction fans 6 are also installed to extract and discharge the water vapor generated during the drying process, preventing water vapor accumulation in the drying chamber 1. Finally, the dried packaging substrate is discharged from the discharge plate 8.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
