Technical Field
[0001] The present application relates to the technical field of preparation of medicinal glass bottles, and in particular to a medicinal glass tube positioning component and a medicinal glass bottle making machine. Background Art
[0002] Medicinal glass bottles are still the preferred packaging for common infusions, antibiotics, general powders, freeze-dried products, vaccines, blood, biological preparations, etc., due to their features of being smooth, transparent, easy to disinfect, corrosion-resistant, high-temperature-resistant, and having good sealing properties. Medicinal glass bottles can be prepared from medicinal glass tubes. For example, controlled antibiotic bottles can be produced using medium borosilicate medicinal glass tubes.
[0003] At present, when a fully automatic intubation machine puts medicinal glass tubes into a medicinal glass bottle making machine (hereinafter referred to as the bottle making machine), the bottle making machine is usually provided with a metal sleeve for receiving the medicinal glass tubes; and when the bottle making machine processes the medicinal glass tubes, the medicinal glass tubes need to be able to rotate at high speed relative to the metal sleeve.
[0004] However, the medicinal glass tube often comes into contact with the metal sleeve during the process of being placed and rotating. Due to the unreasonable setting of the existing metal sleeve structure and fixing method, the friction between the medicinal glass tube and the metal sleeve is very likely to leave scratches on the surface of the prepared medicinal glass bottle, thereby increasing the product scrap rate. Moreover, due to the structural limitations of the metal sleeve, the operator needs to stop the machine regularly to clean impurities inside and outside the sleeve. Otherwise, there is a quality risk of substandard product cleanliness, and the operation is cumbersome. Utility Model Content

[0024] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.
[0025] It should be understood that the terms "upper", "lower", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.
[0026] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0027] In addition, in the description of the present application, “plurality” means two or more than two, unless otherwise clearly and specifically defined.
[0028] by Figures 1 to 3 Taking the example of a pharmaceutical glass tube positioning assembly provided by the present application, the present application provides a pharmaceutical glass tube positioning assembly, which can be configured on a pharmaceutical glass bottle making machine, and specifically can be configured at a station of the pharmaceutical glass bottle making machine for receiving the pharmaceutical glass tubes put in by the fully automatic intubation machine.
[0029] The medicinal glass tube positioning assembly may include multiple fixed sleeves 2 and at least one anti-tilt sleeve group, each anti-tilt sleeve group includes multiple anti-tilt sleeves 3 made of polytetrafluoroethylene, multiple anti-tilt sleeves 3 are detachably sleeved in multiple fixed sleeves 2 and are used to accommodate medicinal glass tubes, and multiple anti-tilt sleeves 3 correspond to multiple fixed sleeves 2 one by one; the above-mentioned fixed sleeves 2 mainly function to fix the anti-tilt sleeves 3 on the bottle making machine; the bottle making machine may also be configured with a clamping device located at the bottom of the anti-tilt sleeve 3, after the fully automatic intubation machine puts the medicinal glass tube into the anti-tilt sleeve 3, the clamping device clamps and fixes its bottom end, and the main function of the anti-tilt sleeve 3 is to circumferentially position the medicinal glass tube to prevent the whole from tilting after the bottom is clamped.
[0030] At the same time, the top end of the inner wall of each fixed sleeve 2 can be formed with a threaded portion 21, which can be understood as an internal thread or an internal thread, and the outer wall of each anti-roll sleeve 3 can be formed with a threaded matching portion 31 corresponding to the threaded portion 21, which can be understood as an external thread or an external thread; and the anti-roll sleeve 3 is a polytetrafluoroethylene sleeve.
[0031] By providing a detachable anti-tilt sleeve 3, the disassembly and regular cleaning of the fixed sleeve 2 and the anti-tilt sleeve 3 are facilitated. At the same time, a threaded portion 21 is formed on the top of the inner circumferential wall of the fixed sleeve 2, and a threaded matching portion 31 corresponding to the threaded portion 21 is formed on the outer circumferential wall of the anti-tilt sleeve 3, so that the anti-tilt sleeve 3 can be fixedly connected with the fixed sleeve 2. After the two are assembled, there is no relative movement during the rotation process (the medicinal glass tube rotates at high speed relative to the anti-tilt sleeve 3), so that the position stability of the anti-tilt sleeve 3 is better, which can minimize the amount of space contained in the anti-tilt sleeve 3. The contact and friction between the medicinal glass tube in the sleeve 3 and the anti-tilt sleeve 3 can reduce the product scrap rate; further, by limiting the anti-tilt sleeve 3 to a polytetrafluoroethylene sleeve, it not only has the characteristics of high temperature resistance, small resistance, and not easy to be contaminated, but also replaces the traditional metal sleeve. It can also reduce the generation of scratches on the medicinal glass bottle, and the material itself is not easy to be polluted, and the cleanliness of the medicinal glass bottle is also greatly improved. The operator does not need to frequently stop the machine to clean the impurities inside and outside the anti-tilt sleeve 3. The operation is simple and effectively reduces the product quality risk.
[0032] In some embodiments, reference may be made to Figure 2 and Figure 3 Each fixed sleeve 2 and each anti-tilt sleeve 3 are cylindrical structures with upper and lower openings, that is, each fixed sleeve 2 and each anti-tilt sleeve 3 have a circular cross-sectional shape; specifically, as Figure 3 As shown, each anti-roll sleeve 3 may include a receiving portion 32 for receiving a medicinal glass tube and a screw-on portion 33 connected to one side of the receiving portion 32, and a threaded fitting portion 31 is formed on the screw-on portion 33. In this way, each anti-roll sleeve 3 may be connected to the fixed sleeve 2 via the threaded fitting portion 31 on the screw-on portion 33. By providing the screw-on portion 33 and the receiving portion 32 on the anti-roll sleeve 3, it is helpful to configure a screw-on portion 33 of the same structure for each anti-roll sleeve 3 so as to be connected to a fixed sleeve 2 of the same specification. By changing the structural dimensions of the receiving portion 32, medicinal glass tubes of different specifications can be accommodated and positioned, thereby helping to achieve multiple uses of the fixed sleeve 2 of the same specification.
[0033] In some embodiments, Figure 3 As shown, the outer diameter of the screw-on portion 33 of each anti-tilt sleeve 3 is larger than the outer diameter of its receiving portion 32. The outer diameter of the receiving portion 32 is set to be smaller than the outer diameter of the screw-on portion 33. On the one hand, it is convenient for each anti-tilt sleeve 3 to be installed in the fixed sleeve 2, reducing the contact and interference between the outer wall surface of the anti-tilt sleeve 3 and the inner wall surface of the fixed sleeve 2; on the other hand, it is convenient for the threaded mating portion 31 on the screw-on portion 33 to be withdrawn during processing without the need to set an additional withdrawal groove; furthermore, the mass of the anti-tilt sleeve 3 can be reduced, thereby reducing the load rate of the power source of the bottle making machine and reducing energy consumption.
[0034] It should be pointed out that the shape and size of the threaded fitting portion 31 on the screw-on portion 33 of each anti-roll sleeve 3 are the same; in other words, the shape and size of the threaded portion 21 in each fixed sleeve 2 are the same; by setting the shape and size of the threaded portion 21 in each fixed sleeve 2 to be consistent, on the one hand, it is convenient for batch and efficient processing of the threaded portion 21 and the threaded fitting portion 31, and on the other hand, it is also helpful to configure the screw-on portion 33 of the same structure for each anti-roll sleeve 3 so as to be connected to the fixed sleeve 2 of the same specification. As a further optimization, a plurality of anti-tilt sleeves 3 can constitute a group of anti-tilt sleeves 3, and the medicinal glass tube positioning assembly includes a plurality of groups of anti-tilt sleeves 3 for accommodating medicinal glass tubes of different specifications, and the inner diameter sizes of the accommodating parts 32 of the same group of anti-tilt sleeves 3 are all the same; the inner diameter sizes of the accommodating parts 32 of different groups of anti-tilt sleeves 3 are all different, that is, on the premise of ensuring that each anti-tilt sleeve 3 is equipped with a screw-on part 33 of the same structure, medicinal glass tubes of different specifications can be accommodated and positioned by changing the inner diameter size of the accommodating part 32, thereby helping to achieve multiple uses of the same specification of the fixed sleeve 2. When it is necessary to position medicinal glass tubes of different specifications, the corresponding anti-tilt sleeve group can be used or replaced and placed in the fixed sleeve 2. The structure is simple and reasonable, and it is easy to operate.
[0035] In some embodiments, the difference between the inner diameter of the receiving portion 32 of each anti-tilt sleeve 3 and the outer diameter of the medicinal glass bottle (such as an antibiotic bottle) prepared by the medicinal glass tube inside it is about 2 mm, so as to ensure that the medicinal glass tube can rotate smoothly in the receiving portion 32 of each anti-tilt sleeve 3. It should be noted that although the numerical ranges and parameters describing the broad scope of the present application are approximate and are defined by "about", the numerical values described in the specific examples are reported as accurately as possible. However, any numerical value inherently contains certain errors, which may be caused by the standard deviation found in their respective test measurements (including the standard deviation found in the measuring instrument).
[0036] In some embodiments, Figure 3 As shown, each anti-tilt sleeve 3 also includes a limiting portion 34 arranged on the side of the screw-on portion 33 away from the accommodating portion 32, and the bottom of the limiting portion 34 abuts against the top of the corresponding fixed sleeve 2; by setting the limiting portion 34, the anti-tilt sleeve 3 can be axially limited when the anti-tilt sleeve 3 is screwed on the fixed sleeve 2. At the same time, by setting the limiting portion 34 and the threaded matching portion 31 on the top of the anti-tilt sleeve 3, a better seal can be formed at the top matching portion of the anti-tilt sleeve 3 and the fixed sleeve 2, preventing impurities from entering between the anti-tilt sleeve 3 and the fixed sleeve 2, and facilitating the cleaning and maintenance of the two. It should be noted that the limiting portion 34 can have a circular cross-sectional shape, and of course it can also be other shapes, which are not limited here.
[0037] In some embodiments, please refer to Figure 2 and Figure 3The bottom of each fixed sleeve 2 is provided with a step portion 22 protruding toward the inside thereof, and each anti-roll sleeve 3 also includes an abutment portion 35 arranged on the side of the accommodating portion 32 away from the screw-on portion 33 and used to abut against the step portion 22; that is, in addition to providing the above-mentioned limiting portion 34, the anti-roll sleeve 3 can also be axially limited by providing the step portion 22 and the abutment portion 35 when the anti-roll sleeve 3 is screwed on the fixed sleeve 2, so that the anti-roll sleeve 3 can be more stably installed in the fixed sleeve 2.
[0038] In some embodiments, a plurality of fixed sleeves 2 are detachably arranged on the rotating disc 1 of the bottle making machine, such as Figure 1 As shown, by arranging a plurality of fixed sleeves 2 and a plurality of anti-tilt sleeves 3 on the rotating disc 1, it is possible to realize that a rotating disc 1 can bear a plurality of medicinal glass tubes, and the plurality of medicinal glass tubes are processed and produced at the same station, thereby improving the production efficiency. It should be noted that the specifications of the same batch of medicinal glass tubes placed on the rotating disc 1 are generally all the same, but of course they may be different. The anti-tilt sleeves 3 of different specifications can be adaptively arranged according to the actual processing conditions, and this is not the only limitation here.
[0039] In some embodiments, please refer to Figure 1 , a plurality of fixed through grooves 100 corresponding to the plurality of fixed sleeves 2 are arranged on the circumferential edge of the rotating disc 1, and the plurality of fixed sleeves 2 are located in the plurality of fixed through grooves 100 and are arranged at intervals from each other along the circumferential direction of the rotating disc 1. The plurality of fixed through grooves 100 may have a circular cross-sectional shape, and may be set to be of uniform size to fix and install a plurality of fixed sleeves 2 of uniform size. The fixed sleeve 2 may be fixed in the fixed through groove 100 by threaded connection or clamping, and the present application is not limited to the above-mentioned connection method. During actual production and processing, the medicinal glass tube may revolve together with the medicinal glass tube positioning assembly around the central axis a of the rotating disc. The fixing method of the fixed sleeve 2 in the above-mentioned embodiment can reduce the friction between the medicinal glass tube contained in the anti-tilt sleeve and the anti-tilt sleeve during the above-mentioned rotation of the medicinal glass tube, thereby further reducing the product scrap rate.
[0040] The present application proposes a medicinal glass bottle making machine, which includes the above-mentioned medicinal glass tube positioning assembly. By setting the above-mentioned medicinal glass tube positioning assembly, the failure downtime rate of the medicinal glass bottle making machine during the production process can be reduced, while the production capacity can be improved; the product scrap rate and labor costs can be reduced; at the same time, the problem of impurities on the surface of the medicinal glass bottle can be reduced, and the cleanliness of the product can be better guaranteed.
[0041] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the implementation methods of the present application. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present application should be included in the protection scope of the claims of the present application.
