Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pharmaceutical and packaging equipment technology, and in particular relates to a capping device and a powder filling machine. Background Technology
[0002] like Figure 1 The irregularly shaped cover shown cannot determine the orientation of the cover when handling it. The cover has a flange on the side, and adjacent covers are prone to overlapping and pressing each other when adding or removing the cover, causing adjacent covers to be lifted and flipped when removing the cover, which affects the stability of the equipment operation. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a capping device and powder filling machine that can achieve stable and efficient operation.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] A capping device includes a horizontally arranged cap conveying channel 1, which is connected to a positioning seat 17. A gap exists between the positioning seat 17 and the cap conveying channel 1. A cap pressing assembly 3 is provided on the cap outlet 2 of the cap conveying channel 1. The cap pressing assembly 3 is used to press the cap inside the cap outlet 2. A bottle conveying channel 4 is provided on the other side of the positioning seat 17. A cap transfer mechanism 5 is provided between the positioning seat 17 and the bottle conveying channel 4. The cap transfer mechanism 5 is used to pick up the cap on the positioning seat 17 and transfer it to the bottle on the bottle conveying channel 4, thereby achieving stable and efficient capping.
[0006] As a further improvement to the above technical solution:
[0007] The cap conveying channel 1 is provided with a cover plate 9, and the cap pressing assembly 3 is fixed to the end of the cover plate 9 to ensure that the cap is conveyed along the cap conveying channel 1.
[0008] The capping assembly 3 includes a mounting base 6 and a pressure plate 8. One end of the pressure plate 8 is a free end, and the other end of the pressure plate 8 is movably connected to the mounting base 6. The pressure plate 8 is used to press the cap and can move above the cap outlet 2.
[0009] The mounting base 6 is provided with a fixed shaft 7, which is positioned across the top of the cover conveying channel 1. A sleeve 13 is fitted on the fixed shaft 7, and a pressure plate 8 is fixedly mounted on the sleeve 13.
[0010] The tablet 8 includes a first horizontal part 10, an inclined part 11, and a second horizontal part 12.
[0011] The cap transfer mechanism 5 includes a translation drive assembly, a lifting drive assembly, and a cap suction head 14. The cap suction head 14 is used to pick up the top of the cap. The translation drive assembly and the lifting drive assembly drive the cap suction head 14 to translate and lift, so that the cap suction head 14 picks up the cap from the positioning seat 17 and transfers it to the bottle body in the bottle conveying channel 4.
[0012] A bottle positioning mechanism 15 is provided on one side of the bottle conveying channel 4. The bottle positioning mechanism 15 is arranged opposite to the cap conveying channel 1, which is a reasonable layout.
[0013] The cap conveying channel 1 is connected to a vibrator 16, which enables horizontal conveying of the cap through vibration. This method is suitable for caps with smooth sidewalls that cannot be conveyed by the cap hanging rail.
[0014] A powder filling machine has a bottle inlet station 18, a first weighing station 19, a powder filling station 20, a second weighing station 21, a capping station 22, a waste removal station 23 and a bottle outlet station 24 arranged sequentially along the bottle conveying channel 4. The capping station 22 is equipped with a capping device as described above.
[0015] The bottle inlet station 18 is connected to the bottle unscrambler 25, and the bottle outlet station 24 is connected to the labeling machine 26.
[0016] Compared with the prior art, the advantages of this utility model are:
[0017] The capping device and powder filling machine of this utility model convey irregularly shaped caps through a horizontally set conveying channel 1. There is a gap between the positioning seat 17 and the cap conveying channel 1 to avoid the cap conveying process of the cap conveying channel 1 affecting the positioning of the cap. The cap on the positioning seat 17 is pushed into place by the cap on the cap conveying channel 1. The gap between the positioning seat 17 and the cap conveying channel 1 reduces the area of flange overlap between adjacent caps. The cap pressing assembly 3 presses the cap in the cap outlet 2 of the cap conveying channel 1. When the cap transfer mechanism 5 picks up the cap on the positioning seat 17, it avoids the irregularly shaped cap flange on the cap outlet 2 pressing the cap on the cap outlet 2, which would cause the cap to be unstable in transfer or cause the cap on the cap outlet 2 to be overturned, affecting the subsequent capping process. This achieves stable and efficient capping and ensures that the powder filling machine can operate stably. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0023] like Figures 2 to 3 As shown, a capping device includes a horizontally arranged cap conveying channel 1, which is connected to a positioning seat 17. There is a gap between the positioning seat 17 and the cap conveying channel 1. A cap pressing assembly 3 is provided on the cap outlet 2 of the cap conveying channel 1. The cap pressing assembly 3 is used to press the cap inside the cap outlet 2.
[0024] The cap conveying channel 1 is connected to the vibrator 16, which realizes horizontal conveying of the cap through vibration. It is suitable for caps with smooth side walls that cannot be conveyed by the cap hanging rail. There is a gap between the positioning seat 17 and the cap conveying channel 1 to avoid the cap conveying process of the cap conveying channel 1 from affecting the positioning of the cap. The cap on the positioning seat 17 is pushed into place by the cap on the cap conveying channel 1. The gap between the positioning seat 17 and the cap conveying channel 1 reduces the area of flange overlap between adjacent caps. The cap pressing assembly 3 presses the cap in the cap outlet 2 of the cap conveying channel 1. When the cap transfer mechanism 5 picks up the cap on the positioning seat 17, it avoids the cap being unable to be transferred stably due to the irregular cap flange on the cap outlet 2 pressing the cap on the cap outlet 2, or the cap on the cap outlet 2 being overturned, affecting the subsequent capping process, so as to achieve stable and efficient capping and ensure the stable operation of the powder filling machine.
[0025] A bottle positioning mechanism 15 is provided on one side of the bottle conveying channel 4, and the bottle positioning mechanism 15 is arranged opposite to the cap conveying channel 1. The bottle conveying channel 4 is provided on the other side of the positioning seat 17. A cap transfer mechanism 5 is provided between the positioning seat 17 and the bottle conveying channel 4. The cap transfer mechanism 5 is used to pick up the cap on the positioning seat 17 and transfer it to the bottle in the bottle conveying channel 4. The bottle is positioned by the bottle positioning mechanism 15, and then the cap transfer mechanism 5 transfers the cap and presses it on the bottle. Since the bottle positioning mechanism 15 is arranged opposite to the cap conveying channel 1 on both sides of the bottle conveying channel 4, the cap transfer mechanism 5 only needs to move horizontally and vertically. The layout is reasonable and the structure is simple and compact.
[0026] The cap transfer mechanism 5 includes a translation drive assembly, a lifting drive assembly, and a cap suction head 14. The cap suction head 14 is used to pick up the top of the cap. The translation drive assembly and the lifting drive assembly drive the cap suction head 14 to translate and lift, so that the cap suction head 14 picks up the cap from the positioning seat 17 and transfers it to the bottle body in the bottle conveying channel 4. The lifting drive assembly includes a servo motor and a lead screw. The servo motor precisely controls the descent position of the cap suction head 14. The cap suction head 14 picks up the cap from the positioning seat 17 and presses the cap onto the bottle body. The structure is simple and compact, and there is no need to set up a separate cap pressing mechanism. The cap transfer and pressing processes are completed by the cap suction head.
[0027] The capping channel 1 is provided with a cover plate 9, and the capping assembly 3 is fixed to the end of the cover plate 9. The cover plate 9 limits the capping from above, ensuring that the cap is always conveyed along the capping channel 1 during the vibration conveying process of the vibrator 16 and will not jump out of the capping channel 1.
[0028] The capping assembly 3 includes a mounting base 6 and a pressure plate 8. One end of the pressure plate 8 is a free end, and the other end of the pressure plate 8 is movably connected to the mounting base 6, allowing the pressure plate 8 to move above the cap outlet 2. While pressing down on the cap inside the cap outlet 2, it does not interfere with the transfer of the cap on the positioning seat 17. During the cap delivery process on the linear vibrating track, the pressure plate 8 uses gravity to press down on the cap to prevent it from being squeezed and lifted by the caps behind it. During the cap suction head 14's cap removal process, because the cap flange of the cap outlet 2 presses against the cap on the positioning seat 17, as the cap suction head lifts the cap, the cap on the cap outlet 2 lifts up until the cap flange on the positioning seat 17 detaches from the cap on the cap outlet 2. The cap on the cap outlet 2 then falls back down under the gravity of the moving pressure plate 8.
[0029] The mounting base 6 is provided with a fixed shaft 7, which is positioned across the top of the cap conveying channel 1. A sleeve 13 is fitted on the fixed shaft 7, and a pressure plate 8 is fixed on the sleeve 13, so that the pressure plate 8 can rotate around the fixed shaft 7 and press the cap on the cap outlet 2 by the weight of the pressure plate 8.
[0030] The pressing plate 8 includes a first horizontal part 10, an inclined part 11, and a second horizontal part 12, which facilitates the processing and molding of the pressing plate 8. The second horizontal part 12 presses down on the cover to prevent scratching the cover.
[0031] A powder filling machine includes, along the bottle conveying channel 4, a bottle inlet station 18, a first weighing station 19, a powder filling station 20, a second weighing station 21, a capping station 22, a waste removal station 23, and a bottle outlet station 24. The capping station 22 is equipped with a capping device as described above. The bottle inlet station 18 connects to a bottle unscrambler 25, and the bottle outlet station 24 connects to a labeling machine 26. After the bottle is capped at the capping station 22 by the capping device, it is inspected by a detection mechanism, which can detect the bottle height by a photoelectric switch or by a vision camera, etc. If the capping is unqualified, it is removed at the waste removal station 23. If the capping is qualified, it is conveyed to the labeling machine 26 at the bottle outlet station 24 for labeling. The powder filling machine completes the precise powder filling and sealing of the bottle, realizing automated production.
[0032] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. 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.
