Description

Technical Field

[0001] This utility model relates to the field of capping machine technology, specifically to a vial capping machine. Background Technology

[0002] A vial capping machine is a device specifically designed for capping and sealing vials. It typically features precise positioning and capping functions to ensure the cap is tightly and accurately pressed onto the vial neck, thus guaranteeing the airtightness and safety of the contents.

[0003] The working principle of a vial capping machine is to place the cap on the mouth of the vial and apply a certain pressure to make it securely sealed. It is widely used in the pharmaceutical, chemical, and food industries, especially in drug production, where it plays a crucial role in ensuring the quality and stability of medicines. However, existing vial capping equipment is divided into manual and pneumatic types. Manual capping pliers have low capping efficiency, while pneumatic capping machines have excessively high costs and maintenance expenses. Utility Model Content

[0004] The purpose of this invention is to provide a vial capping machine to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vial capping machine, comprising: a base, a first rotating shaft rotatably mounted on the base, the first rotating shaft having a spiral groove connected end to end, a limiting block movably sleeved outside the first rotating shaft, a slider fixedly connected to the limiting block, the slider being slidably disposed within the spiral groove connected end to end, a pressing head fixedly connected to the bottom of the limiting block, a support platform mounted above the base, a limiting rod disposed between the base and the support platform, the limiting rod passing through the limiting block, and a turntable rotatably mounted on the base, wherein the first rotating shaft can drive the turntable to rotate intermittently when rotating.

[0006] Furthermore, a sector gear is fixedly sleeved on one end of the first rotating shaft located inside the base, and a spur gear coaxial with the turntable is provided inside the base, the spur gear meshing with the sector gear.

[0007] Furthermore, a second rotating shaft is rotatably disposed inside the base, and the second rotating shaft is connected to the base by a damping bearing. The spur gear is fixedly sleeved outside the second rotating shaft, and the turntable is helically connected to the second rotating shaft.

[0008] Furthermore, straight grooves are provided at the uppermost and lowermost ends of the spiral grooves that are connected end to end.

[0009] Furthermore, the turntable has several storage slots.

[0010] Furthermore, a connecting plate is fixedly connected to the top of the base, and the top of the connecting plate is fixedly connected to the bottom of the support platform.

[0011] Furthermore, a reducer and a motor are fixedly installed on the top of the support platform, and the first rotating shaft is driven to rotate by the motor.

[0012] The beneficial effects of the vial capping machine provided by this utility model in the above technical solution are as follows:

[0013] This invention utilizes a rotating first shaft to cause a limiting block to reciprocate along the axis of the first shaft, thereby driving a pressure head to cap vials placed on a turntable. After capping, as the limiting block begins to move upward, the first shaft drives the turntable to rotate at a certain angle, causing capped vials to be ejected and uncapped vials to be placed directly below the pressure head. This process of repeatedly capping vials is repeated, significantly improving efficiency compared to traditional manual capping pliers. Compared to pneumatic capping machines, it reduces equipment investment costs and maintenance costs.

[0014] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0023] Please see Figures 1-3 A vial capping machine includes: a base 1, a first rotating shaft 7 rotatably mounted on the base 1, a spiral groove 71 connected end to end on the first rotating shaft 7, a limiting block 9 movably sleeved outside the first rotating shaft 7, a slider 91 fixedly connected to the limiting block 9, the slider 91 slidingly disposed within the spiral groove 71, a pressing head 92 fixedly connected to the bottom of the limiting block 9, a support platform 3 mounted above the base 1, a limiting rod 8 disposed between the base 1 and the support platform 3, the top of the limiting rod 8 fixedly connected to the bottom of the support platform 3, the limiting rod 8 passing through the limiting block 9, a hole for the limiting rod 8 to pass through on the limiting block 9, and the limiting rod 8 fixedly connected to the top of the base 1 after passing through the limiting block 9, and a turntable 6 rotatably mounted on the base 1, the first rotating shaft 7 driving the turntable 6 to rotate intermittently.

[0024] The slider 91 is slidably set in the spiral groove 71 connected end to end. By rotating the first rotating shaft 7, the first rotating shaft 7 will inevitably drive the limiting block 9 to rotate together. However, due to the limiting action of the limiting rod 8, the limiting block 9 cannot follow the rotation of the first rotating shaft 7, forcing the limiting block 9 to reciprocate in the axial direction of the first rotating shaft 7. This drives the pressure head 92 to cap the vials placed on the turntable 6. After the capping is completed, when the limiting block 9 starts to move upward, the first rotating shaft 7 drives the turntable 6 to rotate at a certain angle, so that the capped vials are sent out and the uncapped vials are sent directly below the pressure head 92. This process of capping vials to be capped is repeated, which greatly improves the efficiency compared to traditional manual capping pliers. Compared with pneumatic capping machines, it reduces equipment investment costs and maintenance costs.

[0025] Furthermore, a sector gear 72 is fixedly sleeved at one end of the first rotating shaft 7 located inside the base 1. A spur gear 10 coaxial with the turntable 6 is provided inside the base 1. The spur gear 10 meshes with the sector gear 72. The rotation of the first rotating shaft 7 can drive the sector gear 72 to rotate, and the sector gear 72 will drive the spur gear 10 to rotate at a certain angle. This angle is the same as the angle between the adjacent vials placed on the turntable 6 and the axis of the turntable 6, thereby realizing the process of sending out the vials after they are capped and sending the vials to be capped directly below the pressure head 92.

[0026] Furthermore, a second rotating shaft 101 is rotatably installed inside the base 1. The second rotating shaft 101 is connected to the base 1 by a damping bearing. The damping bearing is a commercially available product, and its function is to provide static damping force so that the second rotating shaft 101 remains fixed in any position (without the need for an additional locking structure). The spur gear 10 is fixedly sleeved on the outside of the second rotating shaft 101. The turntable 6 is screwed to the second rotating shaft 101. By turning the turntable 6, the distance between the turntable 6 and the top of the base 1 can be changed, thereby adapting to capping vials of different heights. A limiting component can be set between the turntable 6 and the spur gear 10, such as fixing the two together by a connecting rod, to ensure that the turntable 6 and the spur gear 10 rotate synchronously.

[0027] Furthermore, straight grooves 73 are provided at both the uppermost and lowermost ends of the spiral grooves 71 that are connected end to end, for reference. Figure 2 The uppermost and lowermost horizontal sections of the spiral groove 71, which are connected end to end, are straight grooves 73. When the limiting block 9 moves the pressure head 92 downward, the pressure head 92 wraps around the head of the vial. The mold edge of the pressure head 92 applies radial and axial pressure to the aluminum cap skirt, forcing the aluminum cap skirt to contract towards the bottle mouth flange (the annular protrusion at the bottle neck), forming a mechanical engagement, and further pressing the rubber stopper into the bottle mouth to enhance the sealing performance (the elastic deformation of the rubber stopper assists in the sealing). Because the straight groove 73 is opened in the spiral groove 71, the pressure head 92 will wrap and squeeze the vial cap for a period of time, resulting in a better capping effect for the vial.

[0028] In a further embodiment of this utility model, a plurality of storage slots 61 are provided on the turntable 6. The storage slots 61 are slots opened on the turntable 6 for placing vials. Some symmetrically arranged rubber strips can be pasted into the storage slots 61 so that when the vials are placed into the storage slots 61, the deformation of the rubber strips limits the position of the vials, making the placement of the vials more stable.

[0029] In a further embodiment of this invention, a connecting plate 2 is fixedly connected to the top of the base 1, and the top of the connecting plate 2 is fixedly connected to the bottom of the support platform 3. The base 1 and the support platform 3 are connected together by the connecting plate 2, making the device compact and easy to transport.

[0030] In a further embodiment of this invention, a reducer 4 and a motor 5 are fixedly installed on the top of the support platform 3. The first rotating shaft 7 is driven to rotate by the motor 5. The speed of the motor 5 is changed by setting the reducer 4, thereby adjusting the pressure frequency of the device.

[0031] In this utility model, reference Figures 1 to 3 First, the vials to be capped are placed into the storage slots 61, with one slot 61 corresponding to one vial. Then, the motor 5 is started, driving the first rotating shaft 7 to rotate. The limiting block 9 reciprocates vertically on the first rotating shaft 7. The limiting block 9 moves downward to cap the vials to be capped directly below. As the limiting block 9 moves upward, the pressing head 92 disengages from the vial, and the sector gear 72 meshes with the spur gear 10, causing the spur gear 10 to rotate at a certain angle, so that the turntable 6 rotates at the same angle, sending out the capped vials and sending the vials to be capped directly below the pressing head 92. This process is repeated to achieve continuous capping by the device.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
