Description

Technical Field

[0001] This utility model relates to the field of food and pharmaceutical packaging equipment technology, specifically to a drying device and an automatic production line for columnar materials. Background Technology

[0002] Existing drying devices for cylindrical objects (such as bullets), such as the drying device disclosed in patent US2383474A, use a synchronous belt to transport bullet casings (cylindrical objects) and fix positioning posts on the synchronous belt. The bullet casing (cylindrical shell) is placed outside the positioning posts for transportation and drying. This drying device has the following disadvantages: 1) Because the bullet casing (cylindrical shell) is placed outside the positioning posts, the bullet casing (cylindrical shell) is completely exposed during transportation, which can easily scratch the bullet casing (cylindrical shell) during loading, unloading, or transportation, affecting the subsequent production qualification rate; 2) The positioning posts are fixed on the synchronous belt. If some positioning posts are not fitted with bullet casings (cylindrical shells) during the loading process, the unloaded positioning posts will affect the operation of downstream equipment (such as pharmaceutical powder filling); 3) The synchronous belt occupies a large area, has a short drying time, and has a poor drying effect on bullet casings (cylindrical shells) after dispensing.

[0003] In addition, existing column assembly lines have low automation, require manual loading and unloading multiple times, have low production efficiency, and are prone to scratching the column shell during the loading and unloading process. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a drying device that can realize floating conveying and protect the outer shell of materials from being scratched.

[0005] This invention further provides an automated production line for columnar materials that eliminates the need for multiple manual loading and unloading operations and improves the level of automation.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A drying device includes a single-row conveyor mechanism, a drying mechanism, and multiple carriers. Each carrier is provided with a material receiving hole. The single-row conveyor mechanism is used to convey the carriers. Guide and positioning rails are provided on both sides of the single-row conveyor mechanism to guide and position the carriers. The single-row conveyor mechanism is used to drive the carriers to run sequentially within the drying mechanism.

[0008] As a further improvement to the above technical solution:

[0009] The drying device further includes an input conveying mechanism, an output conveying mechanism, and a return conveying mechanism for conveying the carrier. The input conveying mechanism is connected to the input end of the single-row conveying mechanism, and the input end of the input conveying mechanism is provided with a feeding mechanism. The output conveying mechanism is connected to the output end of the single-row conveying mechanism, and the output end of the output conveying mechanism is provided with a discharging mechanism. The input end of the return conveying mechanism is connected to the output conveying mechanism, and the output end of the return conveying mechanism is connected to the input conveying mechanism.

[0010] The output end of the output conveying mechanism is connected to the input end of the return conveying mechanism via a first feeding wheel, and the output end of the return conveying mechanism is connected to the input end of the input conveying mechanism via a second feeding wheel. The second feeding wheel is also connected to a carrier input wheel.

[0011] The return conveying mechanism is parallel to the input conveying mechanism and the output conveying mechanism at both ends, and is located in the middle near the outside of the drying mechanism.

[0012] The single-row conveyor mechanism is serpentine.

[0013] The vehicle is provided with a first positioning part on both sides, and the guide positioning fence is provided with a second positioning part on each of the opposite sides to cooperate with the first positioning part for positioning.

[0014] The first positioning part is a cylindrical boss, and the second positioning part is an arc-shaped notch that mates with the cylindrical boss.

[0015] The top of the material receiving hole is provided with an inverted conical guide.

[0016] An automated production line for cylindrical objects includes a first assembly device, the aforementioned drying device, a second assembly device, an appearance inspection device, and a weighing and rejecting device that are connected in sequence. The first assembly device is used for feeding and assembling the cylindrical object shell, and the second assembly device is used for feeding and assembling the filler and the cover.

[0017] As a further improvement to the above technical solution:

[0018] A buffer device is provided between the second assembly device and the appearance inspection device.

[0019] Compared with the prior art, the advantages of this utility model are:

[0020] The drying device disclosed in this utility model uses a single-row conveyor mechanism to drive the carriers to run sequentially within the drying mechanism. Materials that enter the drying mechanism first exit first, ensuring the drying time for each material. This effectively dries the materials within the carriers, meeting the needs of production scenarios with strict requirements for material drying time. The carriers are equipped with material receiving holes, into which materials are placed for conveying, preventing them from being completely exposed and protecting their outer shell from scratches. Furthermore, the carriers are guided and positioned on the single-row conveyor mechanism via guide positioning rails, rather than being fixed to it, enabling floating conveying. If a carrier becomes empty, it can be removed, preventing empty carriers from affecting downstream equipment, such as pharmaceutical powder filling equipment.

[0021] The automatic production line for cylindrical objects disclosed in this utility model automatically feeds and assembles the cylindrical object shell and cover in the first assembly device and the second assembly device, respectively. The drying device is equipped with a feeding mechanism, a discharging mechanism and a feeding wheel, which eliminates the need for multiple manual feeding and unloading operations, improves the degree of automation, avoids scratching the cylindrical object shell during frequent manual feeding and unloading, and helps to improve the product qualification rate.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] Example 1

[0031] Figure 1 and Figure 2 An embodiment of the drying device of this utility model is shown. The drying device of this embodiment includes a single-row conveying mechanism 1, a drying mechanism 2 and multiple carriers 3. The carriers 3 are provided with material receiving holes 31. The single-row conveying mechanism 1 is used to convey the carriers 3. The single-row conveying mechanism 1 is provided with guide positioning rails 4 on both sides. The guide positioning rails 4 guide and position the carriers 3. The single-row conveying mechanism 1 is used to drive the carriers 3 to run sequentially in the drying mechanism 2.

[0032] In this drying device, a single-row conveyor mechanism 1 drives the carrier 3 to run sequentially within the drying mechanism 2. The material that enters the drying mechanism 2 first exits first, ensuring the drying time for each material. This effectively dries the material in the carrier 3 within the drying mechanism 2, meeting the needs of production scenarios with strict requirements for material drying time. The carrier 3 is equipped with a material receiving hole 31, into which the material is placed for conveying, preventing the material from being completely exposed and protecting the outer shell from scratches. At the same time, the carrier 3 is guided and positioned on the single-row conveyor mechanism 1 by a guide positioning railing 4, rather than being fixed to the single-row conveyor mechanism 1, enabling floating conveying. If the carrier 3 is empty, it can be removed, preventing the empty carrier 3 from affecting the operation of downstream equipment, such as pharmaceutical powder filling equipment.

[0033] Furthermore, in this embodiment, the drying device also includes an input conveying mechanism 5, an output conveying mechanism 6, and a return conveying mechanism 7 for conveying the carrier 3. The input conveying mechanism 5 is connected to the input end of the single-row conveying mechanism 1, and the input end of the input conveying mechanism 5 is equipped with a feeding mechanism. The output conveying mechanism 6 is connected to the output end of the single-row conveying mechanism 1, and the output end of the output conveying mechanism 6 is equipped with a discharging mechanism. The input end of the return conveying mechanism 7 is connected to the output conveying mechanism 6, and the output end of the return conveying mechanism 7 is connected to the input conveying mechanism 5. The feeding mechanism places the material into the carrier 3 at the input end of the input conveying mechanism 5. The input conveying mechanism 5 drives the carrier 3 to be conveyed to the single-row conveying mechanism 1. The single-row conveying mechanism 1 drives the carrier 3 to run sequentially in the drying mechanism 2 to dry the material. After drying, the material is output through the output conveying mechanism 6. When the material is conveyed to the output end of the output conveying mechanism 6, it is discharged through the discharging mechanism. After the material is discharged, the empty carrier 3 continues to flow back to the input conveying mechanism 5 through the return conveying mechanism 7 for recycling, thereby improving the conveying efficiency. It should be noted that the input conveying mechanism 5, the single-row conveying mechanism 1, the output conveying mechanism 6, and the return conveying mechanism 7 can all be the same single-row conveyor belt.

[0034] Furthermore, in this embodiment, the output end of the output conveying mechanism 6 is connected to the input end of the return conveying mechanism 7 via the first feeding dial 8, and the output end of the return conveying mechanism 7 is connected to the input end of the input conveying mechanism 5 via the second feeding dial 9. The second feeding dial 9 is also connected to the carrier input dial 10. The connection between the conveying mechanisms via the dials not only changes the conveying direction and compacts the overall structure, but also plays a certain buffering role, facilitating loading and unloading. The second feeding dial 9 can supplement the carrier 3 according to the actual production situation to ensure the conveying effect.

[0035] Furthermore, in this embodiment, the two ends of the return conveying mechanism 7 are parallel to the input conveying mechanism 5 and the output conveying mechanism 6, respectively, and the middle part is located near the outer side of the drying mechanism 2. This further makes the overall structure more compact and reduces the footprint of the conveying mechanism.

[0036] Furthermore, in this embodiment, the single-row conveyor mechanism 1 is serpentine. That is, the single-row conveyor mechanism 1 drives the carrier 3 to circulate within the drying mechanism 2, extending the material drying time and improving the drying effect.

[0037] Furthermore, in this embodiment, the carrier 3 is provided with first positioning parts 32 on both sides, and the guide positioning fence 4 is provided with second positioning parts 41 on both opposite sides, which cooperate with the first positioning parts 32 for positioning. The first positioning parts 32 and the second positioning parts 41 cooperate to position and guide the transport of the carrier 3.

[0038] Furthermore, in this embodiment, the first positioning part 32 is a cylindrical boss, and the second positioning part 41 is an arc-shaped recess that mates with the cylindrical boss. Since the single-row conveying mechanism 1 travels around the drying mechanism 2 and needs to make multiple turns, the positioning by the cylindrical boss and the arc-shaped recess not only simplifies the structure but also facilitates the travel and turning.

[0039] Furthermore, in this embodiment, the top of the material receiving hole 31 is provided with an inverted conical guide portion 311. This facilitates the placement of material into the material receiving hole 31 and reduces scratches on the material.

[0040] Example 2

[0041] Figure 3 This invention illustrates an embodiment of an automated production line for cylindrical objects. The automated production line for cylindrical objects in this embodiment includes a first assembly device 11, the aforementioned drying device, a second assembly device 12, an appearance inspection device 13, and a weighing and rejecting device 14 connected in sequence. The first assembly device 11 is used for feeding and assembling the cylindrical object shell, and the second assembly device 12 is used for feeding and assembling the filler and the cover.

[0042] This automated production line for cylindrical products has a first assembly unit 11 for feeding and assembling cylindrical shells. After drying in a drying unit 2, the cylindrical shells are filled with powder and capped in a second assembly unit 12. The assembled cylindrical products undergo appearance inspection in an appearance inspection device 13 to ensure a high pass rate. Qualified cylindrical products then enter a weighing and rejection device 14 for weighing, and defective bottles are rejected, ensuring a high yield rate for cylindrical product production. The cylindrical shells and caps are automatically fed and assembled in the first assembly unit 11 and the second assembly unit 12, respectively. The drying unit 2 is equipped with a feeding mechanism, a discharging mechanism, and a feeding wheel, eliminating the need for multiple manual loading and unloading operations, thus improving automation and preventing scratches on the cylindrical shells during frequent manual loading and unloading, ultimately increasing the product pass rate.

[0043] Furthermore, in this embodiment, a buffer device 15 is provided between the second assembly device 12 and the appearance inspection device 13. The buffer device 15 can buffer a certain amount of assembled columnar objects. When the devices at the front end of the buffer device 15 malfunction or stop, the appearance inspection device 13 and the devices at the back end can operate normally to ensure the production rhythm.

Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
