Description

Technical Field

[0001] This utility model relates to the field of filling equipment technology, and in particular to a filling and sealing mechanism. Background Technology

[0002] Currently, creams are one or more liquid agents that are poorly soluble in water or solid agents that are soluble in a suitable organic solvent. They are processed by adding dispersants to form a paste-like preparation. The creams are then packaged. Cream filling and sealing machines are devices used to fill and seal the end of a tube (whose head is pre-sealed and its tail is open, and the tube body is cylindrical). They are widely used in the pharmaceutical, daily cosmetic, food, and adhesive industries.

[0003] Currently, the outer diameter of the tubes used for filling creams varies, but the hole diameter for placing the tubes on existing cream filling and sealing machines is fixed, making it inconvenient to fix tubes of different outer diameters. In addition, existing filling and sealing machines still have label misalignment after sealing, resulting in a reduced yield. Utility Model Content

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

[0044] Furthermore, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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 between 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.

[0045] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium.

When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0047] like Figures 1-3 As shown, this embodiment provides a filling and sealing mechanism for filling and sealing a hose, having a first direction X, a second direction Y, and a third direction Z that intersect each other.

[0048] In some implementations, the first direction X, the second direction Y, and the third direction Z intersect each other perpendicularly.

[0049] In some embodiments, the filling and sealing mechanism includes a frame 10, a moving component 20, a vision positioning component 30, and a heat sealing component 40.

[0050] In the specific implementation method, please refer to Figures 1-2 The moving component 20 includes a support platform 21, a first drive unit 23, a moving stage 26, a material cylinder 28, and a second drive unit 29. The support platform 21 is mounted on the frame 10 and extends along a first direction X. The first drive unit 23 is disposed on the support platform 21. The moving stage 26 is slidably connected to the support platform 21. The first drive unit 23 is configured to drive the moving stage 26 to move along the first direction X. The second drive unit 29 is disposed on the moving stage 26. The material cylinder 28 is disposed at the output end of the second drive unit 29. The second drive unit 29 is configured to drive the material cylinder 28 to rotate. The visual positioning component 30 is disposed on the frame 10 and is configured to identify the label at the end of the hose. The heat sealing component 40 is disposed on the frame 10 and is used to heat seal the end of the hose. In this embodiment, the first driving unit 23 can drive the moving stage 26 to move along the first direction X, so that the hose can move between the vision positioning component 30 and the heat sealing component 40. When the hose is at the corresponding position of the vision positioning component 30, the second driving unit 29 can drive the material cylinder 28 to rotate, so that the label at the end of the hose is aligned with the vision positioning component 30 and captured. After the hose is filled with material, it moves to the heat sealing component 40 for heat sealing. This can avoid the label misalignment of the hose after heat sealing and improve the yield.

[0051] In addition, the material cylinder 28 is equipped with a clamping component for clamping the hose, which can meet the fixing of hoses with different outer diameters, improve applicability, avoid the need to change different material cylinders due to different pipe diameters, save time, and improve production efficiency.

[0052] In some embodiments, the heat sealing end assembly 40 is in two sets and is arranged opposite to each other on the frame 10 along the second direction Y. When sealing, the two sets of heat sealing end assemblies 40 can approach each other along the second direction Y and squeeze the end of the hose so that the end of the hose is heated and bonded.

[0053] In some embodiments, the first drive unit 23 is preferably a linear cylinder; in other embodiments, a linear motor may be used instead of a linear cylinder.

[0054] In some embodiments, the moving component 20 further includes a mounting plate 22, which is mounted on the support platform 21, and the first drive unit 23 is connected to the mounting plate 22, thereby achieving fixed installation of the first drive unit 23.

[0055] In some embodiments, to ensure the smooth sliding of the movable stage 26 on the support platform 21, the mounting plate 22 is provided with at least one guide rail 24 extending along a first direction X, and the movable stage 26 is provided with at least one slider 25, which is slidably connected to the at least one guide rail 24. In this way, the cooperation between the slider 25 and the guide rail 24 can reduce the friction between the movable stage 26 and the support platform 21, avoid the generation of abnormal noise, and improve the smoothness and flexibility of the movement of the movable stage 26.

[0056] In some embodiments, the output end of the first drive unit 23 is provided with a push rod 27, which extends along the first direction X and is connected to the moving stage 26. Thus, the first drive unit 23 can drive the push rod 27 to move the moving stage 26 along the guide rail 24.

[0057] In some embodiments, to improve the stability and balance of the moving stage 26, two sliders 25 are preferred, and two guide rails 24 are preferred, with the two sliders 25 respectively connected to the two guide rails 24; this makes the moving stage 26 more stable during movement and prevents tilting.

[0058] In some implementation methods, please refer to Figure 2The material cylinder 28 includes a cylinder body 281, which has an upward-facing inlet 282 in the third direction Z. The clamping component includes at least two clamping bars 283 and a third drive unit 284. The at least two clamping bars 283 are spaced apart on the inner circumference of the cylinder body 281. The third drive unit 284 is located on the inner wall of the cylinder body 281, and its output end is connected to the clamping bars 283. The third drive unit 284 is configured to drive the clamping bars 283 to move radially along the cylinder body 281. Thus, when the hose enters the cylinder body 281 through the inlet, the third drive unit 284 drives the clamping bars 283 to approach and press the hose, thereby fixing the hose and ensuring that the hose can rotate synchronously when the cylinder body 281 rotates, thereby achieving position adjustment and improving the product sealing qualification rate.

[0059] In some embodiments, there are two clamping bars 283 arranged opposite each other; in another embodiment, there are three clamping bars 283, with the angle between two adjacent clamping bars 283 and the axis of the cylinder 281 being 120°; in yet another embodiment, there are four clamping bars 283, with the angle between two adjacent clamping bars 283 and the axis of the cylinder 281 being 90°; in other embodiments, there may be five, six or even more clamping bars 283.

[0060] In some embodiments, the clamping bar 283 has a guide surface 283a and an anti-slip surface 283b on the side away from the third drive unit 284. The guide surface 283a is close to the feed port 282. The guide surface 283a can guide the hose to quickly enter the cylinder 281, improving operating efficiency. The anti-slip surface 283b allows the clamping bar 283 to fit tightly against the outer wall of the hose, thereby achieving the clamping effect on the hose and avoiding mechanical friction between the hose and the clamping bar 283 during the synchronous rotation of the cylinder 281 and the hose.

[0061] In some embodiments, the guide surface 283a is a guide slope, and the acute angle θ formed by the guide surface 283a and the anti-slip surface 283b satisfies: 20°≤θ≤50°; the guide slope makes it easier for the hose to enter the cylinder 281, improving operating efficiency.

[0062] In some embodiments, the guide surface 283a is a guide arc surface, with the convex surface of the guide surface 283a facing the feed port 282. The guide arc surface makes it easier for the hose to enter the cylinder 281, improving operating efficiency.

[0063] In some embodiments, during the process of the second drive unit 29 driving the barrel 28 to rotate, in order to avoid mechanical friction between the head of the hose and the barrel 281, a gasket 285 is provided at the inner bottom of the barrel 281. The gasket 285 is provided to protect the head of the hose.

[0064] In some embodiments, the gasket 285 is a silicone gasket. The silicone gasket has a shock-absorbing function and a certain degree of elasticity. During the process of inserting the hose into the cylinder 281, the head of the hose will not collide with the cylinder 281, thereby protecting the hose.

[0065] In other embodiments, the gasket 285 may also be a rubber gasket or a sponge gasket, which serves the same function as a silicone gasket.

[0066] In some embodiments, the visual positioning component 30 includes a support 31, a pole 32, a support member, and a visual camera 36. The support 31 is mounted on the frame 10, the pole 32 is mounted on the support 31 along a third direction Z, the support member is mounted on the pole 32, and the visual camera 36 is mounted on the support member. In a specific embodiment, the support member includes a first support member 33 and a second support member 34. The first support member 33 is connected to the pole 32, and the second support member 34 is connected to the first support member 33 via a connector 35. Thus, the first support member 33 can adjust the height of the visual camera 36 along the pole 32 in the third direction Z. The second support member 34, connected to the first support member 33 via the connector 35, can adjust the angle of the visual camera 36 in the horizontal plane, allowing the visual camera 36 to adjust its position according to the diameter of the hose, enabling the visual camera 36 to effectively identify the label at the end of the hose and improve the sealing success rate.

[0067] In some embodiments, to meet the filling requirements of the hose, the filling and sealing mechanism further includes a filling tube head 50, which is located on the frame 10 and positioned above the moving component 20 along the third direction Z. The filling tube head 50 is connected to the material tank for filling the hose.

[0068] In other embodiments, the injection tube head 50 can be mounted on a multi-axis robot or a multi-axis gantry to improve the flexibility of the injection tube head 50, enabling it to move flexibly in the first direction X, the second direction Y, and the third direction Z to meet the needs of injecting material into the hose and improve efficiency.

[0069] The working process of this utility model is as follows: Please refer to... Figures 1-3In operation, the first drive unit 23 pre-extends the barrel 28 via the push rod 27, then pre-seals the head of the hose with a cap and inserts it head-down into the barrel 281, with the tail of the hose open and positioned outside the barrel 281. The third drive unit 284 drives the clamping bar 283 to approach and press against the hose, thereby fixing it in place. The second drive unit 29 drives the barrel 28 to rotate synchronously with the hose until the vision camera 36 detects and identifies the label at the tail of the hose. At this point, the second drive unit 29 stops, and the first drive unit 23, via the push rod... 27 drives the material cylinder 28 to move directly below the injection tube head 50, or the injection tube head 50 moves on the multi-axis robot or multi-axis gantry to above the material cylinder 28, so that the injection tube head 50 is aligned with the tail opening of the hose, and the material is injected into the hose. After injection, the first drive unit 23 drives the material cylinder 28 to the heat sealing assembly 40 through the push rod 27. The two sets of heat sealing assemblies 40 approach each other along the second direction Y and squeeze the tail of the hose, so that the tail of the hose is heated and bonded, thereby realizing the sealing action. Finally, the hose is taken out from the material cylinder 28, waiting for the next hose to be inserted.

[0070] In summary, this utility model embodiment provides a filling and sealing mechanism, which, by setting a first driving unit 23, can drive a moving stage 26 to move along a first direction X, so that the tube can move between the visual positioning component 30 and the heat sealing component 40. When the tube is at the corresponding position of the visual positioning component 30, the second driving unit 29 can drive the material cylinder 28 to rotate, so that the label at the end of the tube is aligned with the visual positioning component 30 and captured. After the tube is filled with material, it moves to the heat sealing component 40 for heat sealing. This can avoid label misalignment after heat sealing and improve the yield.

[0071] In addition, the material cylinder 28 is equipped with a clamping component for clamping the hose, which can meet the fixing of hoses with different outer diameters, improve applicability, avoid the need to change different material cylinders due to different pipe diameters, save time, and improve production efficiency.

[0072] The above description is merely a preferred embodiment of this utility model. It should be noted that, for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this utility model, and these improvements and substitutions should also be considered within the protection scope of this utility model. The basic principles, main features, and advantages of this utility model have been shown and described above. For those skilled in the art, it is obvious that this utility model is not limited to the details of the above preferred embodiments. The embodiments should be considered exemplary and non-limiting. The scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included within this utility model.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in the embodiments can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
