Description

Technical Field

[0001] This utility model relates to the field of glass tube processing technology, and in particular to a spraying device for pharmaceutical glass tubes. Background Technology

[0002] In the production and processing of glass tubes, a protective liquid is usually sprayed onto their surface to improve their corrosion resistance, wear resistance, and other properties. Existing pharmaceutical glass tube spraying equipment generally uses nozzles to spray the glass tubes, but in practical applications, this type of spraying equipment has many problems.

[0003] Traditional spray nozzles typically employ a standard conical spray pattern. When the glass tube diameter is small, the spray areas of multiple nozzles tend to overlap significantly, resulting in excessively thick protective liquid coating in the overlapping areas. This not only wastes the protective liquid but also affects the uniformity and quality of the coating on the glass tube surface. Conversely, when the glass tube diameter is large, the spray area may not completely cover the glass tube surface, creating spray blind spots and leading to uneven coating of the protective liquid, thus failing to provide effective protection. Furthermore, existing spraying devices mostly have fixed nozzle angles, making it difficult to flexibly adjust the spray direction and spray area according to the actual diameter of the glass tube. This results in poor applicability of the spraying device, failing to meet the coating needs of glass tubes of different specifications, significantly limiting production efficiency and product quality, and increasing production costs. Utility Model Content

[0004] This invention provides a spraying device for pharmaceutical glass tubes to solve the problem of fixed nozzles and difficulty in adjusting the spray coverage of existing devices.

[0005] To alleviate the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A pharmaceutical glass tube spraying device includes a conveying mechanism for conveying glass tubes, a spraying mechanism is provided on the conveying mechanism, the spraying mechanism includes a sliding frame connected to the conveying mechanism, and a plurality of nozzles are arranged in a circular array on the sliding frame, the spraying shape of the plurality of nozzles being fan-shaped.

[0007] The multiple nozzles can swing relative to the sliding frame, and when the multiple nozzles swing synchronously and in the same direction, the overlapping area of ​​the spray from two adjacent nozzles changes.

[0008] Furthermore, the spraying mechanism also includes a housing, the middle of which has a through hole that mates with the glass tube, and the sliding frame slides within the housing.

[0009] Furthermore, the through hole in the middle of the outer shell is fitted with the glass tube with a clearance.

[0010] Furthermore, multiple gears are rotatably connected to the sliding frame, and mounting seats are fixedly connected to the side walls of each of the multiple gears. The nozzle is fixedly connected to the mounting seat, and multiple sets of teeth are provided inside the housing to mesh with the multiple gears.

[0011] Furthermore, multiple connecting rods are fixedly connected to the sliding frame, and the ends of the multiple connecting rods are jointly fixedly connected to a ring. An electric push rod is fixedly connected to the conveying mechanism, and the output end of the electric push rod is fixedly connected to the ring.

[0012] Furthermore, the conveying mechanism is equipped with a distance sensor located at the top of the glass tube. When the diameter of the glass tube decreases, the distance between the distance sensor and the glass tube increases, thereby extending the electric push rod to allow the sliding frame to slide, thus changing the nozzle from a vertical state to an inclined state.

[0013] Furthermore, there are two electric push rods, and the two electric push rods are symmetrically connected to the conveying mechanism.

[0014] Furthermore, the conveying mechanism includes a conveying frame, within which a plurality of conveying wheels are rotatably connected in a linear array, and the glass tube is driven on the upper part of the plurality of conveying wheels.

[0015] Furthermore, the conveyor frame has a notch, and the outer shell is fixedly connected to the notch.

[0016] Furthermore, a bracket is fixedly connected within the notch, and the outer shell is fixedly connected to the bracket.

[0017] The beneficial effects of this utility model are analyzed as follows:

[0018] A pharmaceutical glass tube spraying device includes a conveying mechanism for conveying glass tubes, a spraying mechanism on the conveying mechanism, and a sliding frame connected to the conveying mechanism. Multiple nozzles are arranged in a circular array on the sliding frame, and the spraying shape of the multiple nozzles is fan-shaped. The multiple nozzles can swing relative to the sliding frame, and when the multiple nozzles swing synchronously and in the same direction, the area of ​​the overlapping spraying part of two adjacent nozzles changes.

[0019] The glass tube passes through the middle of the sliding frame, and the nozzle starts spraying protective liquid onto the glass tube. The spray trajectory of the nozzle is close to a two-dimensional fan shape rather than a standard cone shape, ensuring that the thickness of the protective liquid sprayed onto the glass tube is as required. When the nozzle is vertically pointed at the glass tube, if the diameter of the glass tube is small, the spray trajectories of two adjacent nozzles will intersect. At this time, the thickness of the protective liquid sprayed at the intersection is higher. In this case, the nozzle is controlled to swing on the sliding frame so that the spray direction of the nozzle is no longer perpendicular to the glass tube, thereby changing the area of ​​the intersection of the spray trajectories of two adjacent nozzles. By adjusting the area of ​​the intersection, the protective liquid can be sprayed more evenly on the glass tube, which is conducive to the subsequent processing of the glass tube.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Examples, such as Figures 1-5 As shown, a pharmaceutical glass tube spraying device includes a conveying mechanism 100 for conveying glass tubes, a spraying mechanism 200 disposed on the conveying mechanism 100, and a sliding frame 220 connected to the conveying mechanism 100. A plurality of nozzles 250 are arranged in a circular array on the sliding frame 220, and the spraying shape of the plurality of nozzles 250 is fan-shaped. The plurality of nozzles 250 can swing relative to the sliding frame 220, and when the plurality of nozzles 250 swing synchronously and in the same direction, the area of ​​the overlapping spraying part of two adjacent nozzles 250 changes.

[0032] Working mechanism of the pharmaceutical glass tube spraying device provided in this embodiment:

[0033] The glass tube passes through the center of the sliding frame 220, and simultaneously the nozzle 250 is activated to spray a protective liquid onto the glass tube. The spray trajectory of the nozzle 250 is close to a two-dimensional fan shape rather than a standard cone shape, ensuring that the thickness of the protective liquid sprayed onto the glass tube reaches the required level. Figure 4 and Figure 5As shown, when the nozzle 250 is vertically pointed at the glass tube, if the diameter of the glass tube is small, the spray trajectories of two adjacent nozzles 250 will intersect. At this time, the thickness of the protective liquid sprayed at the intersection is higher. In this case, the nozzle 250 is controlled to swing on the sliding frame 220 so that the spray direction of the nozzle 250 is no longer perpendicular to the glass tube. This changes the area of ​​the intersection of the spray trajectories of two adjacent nozzles 250. By adjusting the area of ​​the intersection, the protective liquid can be sprayed more evenly on the glass tube, which is beneficial for the subsequent processing of the glass tube.

[0034] Among the optional methods in this embodiment, the more preferred one is:

[0035] The spraying mechanism 200 also includes a housing 210, with a through hole in the middle of the housing 210 that mates with the glass tube, and a sliding frame 220 sliding inside the housing 210.

[0036] The sliding frame 220 and the nozzle 250 connected to the sliding frame 220 are both located inside the housing 210, so that the protective liquid sprayed by the nozzle 250 that does not adhere to the glass tube can be collected inside the housing 210, preventing the protective liquid from spreading in the workshop and preventing the waste of raw materials.

[0037] Among the optional methods in this embodiment, the more preferred one is:

[0038] Multiple gears 230 are rotatably connected to the sliding frame 220. Mounting bases 240 are fixedly connected to the side walls of the multiple gears 230. The nozzle 250 is fixedly connected to the mounting base 240. Multiple sets of teeth that mesh with the multiple gears 230 are provided inside the outer casing 210.

[0039] When the sliding frame 220 slides, the gear 230 rotatably connected to the sliding frame 220 can roll on the teeth inside the housing 210, thereby rotating the gear 230 and driving the nozzle 250 to swing, so that the intersection area of ​​the spray from two adjacent nozzles 250 changes. The nozzle 250 is fixed to the mounting base 240 by a threaded connection. By rotating the nozzle 250, the distance between the nozzle 250 and the glass tube in the vertical state can be adjusted, thereby ensuring that the spray can completely cover the glass tube with a larger diameter.

[0040] Among the optional methods in this embodiment, the more preferred one is:

[0041] Multiple connecting rods 270 are fixedly connected to the sliding frame 220, and the ends of the multiple connecting rods 270 are fixedly connected to a ring 260. An electric push rod 280 is fixedly connected to the conveying mechanism 100, and the output end of the electric push rod 280 is fixedly connected to the ring 260.

[0042] The diameter of the connecting rod 270 is smaller than that of the electric push rod 280. The electric push rod 280 enables the sliding frame 220 to slide inside the housing 210 through the transmission of the ring 260 and the connecting rod 270. The housing 210 has a through hole that mates with the connecting rod 270, so that the atomized protective liquid will not easily leak from the connecting rod 270.

[0043] Among the optional methods in this embodiment, the more preferred one is:

[0044] A distance sensor 290 is provided on the conveying mechanism 100. The distance sensor 290 is located on the upper part of the glass tube. When the diameter of the glass tube decreases, the distance between the distance sensor 290 and the glass tube increases, thereby extending the electric push rod 280 so that the sliding frame 220 slides, and the nozzle 250 changes from a vertical state to an inclined state. When the diameter of the glass tube increases, the distance between the distance sensor 290 and the glass tube decreases, thereby shortening the electric push rod 280 so that the sliding frame 220 slides, and the nozzle 250 swings from an inclined state to a vertical state.

[0045] The distance sensor 290 can be ultrasonic or optical. The distance sensor 290 determines the diameter of the glass tube by detecting the distance between itself and the glass tube. After obtaining the diameter of the glass tube through the distance sensor 290, the control system controls whether the electric push rod 280 extends or retracts. When the diameter of the glass tube is large, the electric push rod 280 extends, and the sliding frame 220 slides, so that the gear 230 rolls on the corresponding teeth, causing the spray angle of the nozzle 250 to change to an inclined state. This reduces or even eliminates the area of ​​the overlapping spray of multiple nozzles 250, ensuring that the protective liquid is evenly sprayed on the glass tube. Conversely, when the diameter is small, the electric push rod 280 shortens, causing the spray angle of the nozzle 250 to tend to a vertical state.

[0046] Among the optional methods in this embodiment, the more preferred one is:

[0047] There are two electric push rods 280, and the two electric push rods 280 are symmetrically connected to the conveying mechanism 100.

[0048] By setting two electric push rods 280, the sliding frame 220 is subjected to a uniform pushing force, preventing the sliding frame 220 from getting stuck in the outer shell 210 due to uneven force.

[0049] Among the optional methods in this embodiment, the more preferred one is:

[0050] The through hole in the middle of the outer casing 210 is fitted with the glass tube with a clearance.

[0051] The two are set to a clearance fit to ensure that the protective liquid will not be scraped off by the hole wall when the glass tube is removed from the housing 210 after being sprayed. At the same time, the axial position of the housing 210 relative to the glass tube is adjusted to adapt to the spraying of glass tubes of different diameters.

[0052] Among the optional methods in this embodiment, the more preferred one is:

[0053] The conveying mechanism 100 includes a conveying frame 110, in which multiple conveying wheels 120 are rotatably connected in a linear array, and the glass tube is driven by the upper part of the multiple conveying wheels 120.

[0054] The conveyor wheel 120 is driven to rotate by an external motor. Multiple conveyor wheels 120 are connected by chain drive to ensure that multiple conveyor wheels 120 can rotate synchronously to convey glass tubes.

[0055] Among the optional methods in this embodiment, the more preferred one is:

[0056] The conveyor frame 110 has a notch 130, and the outer shell 210 is fixedly connected to the notch 130.

[0057] The opening of notch 130 provides space for the installation of housing 210. A through hole is opened at the bottom of housing 210, and a container is placed at the bottom of notch 130 to collect the protective fluid discharged from the through hole at the bottom of housing 210.

[0058] Among the optional methods in this embodiment, the more preferred one is:

[0059] A bracket is fixedly connected inside the notch 130, and the outer shell 210 is fixedly connected to the bracket.

[0060] The bracket is height-adjustable and driven by an electric telescopic rod, hydraulic rod, or cylinder. When the distance sensor 290 detects a change in the diameter of the glass tube, the bracket rises or falls so that the through hole in the middle of the housing 210 can be kept coaxial with the glass tube, ensuring that the distance between the multiple nozzles 250 and the glass tube is equal and guaranteeing the uniformity of the spraying.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
