Description

Technical Field

[0001] This utility model relates to the technical field of filling machines, specifically a lifting and adjusting mechanism for a filling machine. Background Technology

[0002] Filling machines are widely used in pharmaceuticals, food, daily chemicals, and oils, and can fill various liquid and paste products, such as disinfectants and beverages. Currently, in bottle-bottom filling machines, when filling bottles of different heights, the height of the filling machine needs to be adjusted to ensure that the distance between the filling valve and the bottle mouth remains consistent, thus ensuring a smooth filling process.

[0003] The existing lifting and adjusting structure of the filling machine integrates the drive unit, gear ring, lifting unit and other components on the top of the support plate. The end of the lifting unit away from the support plate is used to install the bottle placement platform. This causes water to easily accumulate on the support plate during bottle cleaning, making it difficult to clean and prone to bacterial growth over time. Secondly, directly setting the lifting unit between the support plate and the bottle placement platform can easily increase the load on the lifting unit. Especially when the lifting unit extends, the lateral vibration generated during cleaning or filling affects the lifting accuracy of the lifting unit. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting and adjusting mechanism for a filling machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting and adjusting mechanism for a filling machine, comprising a bracket, a gear ring, and a driving component mounted on the bracket for driving the gear ring to rotate; a plurality of lifting components mounted on the bracket, each lifting component including a threaded lifting unit mounted on the bracket and whose movable end is connected to a bottle-laying platform; further comprising: a centering support component connected to the threaded lifting unit and used to support the gear ring, wherein the driving end of the threaded lifting unit is fixed with a driven gear meshing with the gear ring.

[0006] The lifting and adjusting mechanism for the filling machine as described above: the threaded lifting unit includes: a threaded sleeve rotatably mounted on the bracket, a threaded sleeve fixed inside the threaded sleeve, and the drive end formed on the threaded sleeve at the position for fixing the driven gear; a screw rod passing through the threaded sleeve and extending into the threaded sleeve, and threadedly connected to the threaded sleeve, with the end of the screw rod away from the threaded sleeve forming the movable end.

[0007] The lifting and adjusting mechanism for the filling machine as described above: the threaded sleeve passes through the bracket and is connected to the first bearing seat and the second bearing seat installed at the upper and lower ends of the bracket.

[0008] The lifting and adjusting mechanism for the filling machine as described above: the centering support includes: a centering seat mounted on the frame and a centering component fixedly mounted on the centering seat, wherein the centering component and the driven gear form a receiving space for inserting the gear ring.

[0009] The lifting and adjusting mechanism for the filling machine as described above: the centering member is arranged in a columnar structure, and its outer wall has an annular inner insert for receiving the gear ring. The diameter of the circle at the end of the annular inner insert of the plurality of centering members facing the driven gear is equal to the inner diameter of the gear ring.

[0010] The lifting and adjusting mechanism for the filling machine as described above: a protective cover is fitted on the outside of the lead screw located between the bottle placement platform and the support.

[0011] The lifting and adjusting mechanism for the filling machine as described above: the driving component includes: a motor mounted on the bracket via a motor mount, the output shaft of the motor having a drive gear that meshes with the gear ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the centering support component effectively supports the toothed ring, allowing the toothed ring to be suspended in the air; at the same time, the lifting component is installed through the bracket, so that there is no support platform below the toothed ring, thus eliminating the problem of water accumulation on the support platform when cleaning the bottle.

[0013] The multiple threaded lifting units are connected to the gear ring via driven gears. When the gear ring rotates, the lifting of multiple lifting components can be synchronized, ensuring the synchronicity and stability of the bottle-laying platform. The design of the centering support not only effectively supports the gear ring but also ensures the stability of the gear ring during rotation, thereby further improving the stability and reliability of the cleaning process.

The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0022] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0023] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0024] Please see Figures 1-5 In this embodiment of the present invention, a lifting and adjusting mechanism for a filling machine includes a bracket 1, a gear ring 3, and a driving component mounted on the bracket 1 for driving the gear ring 3 to rotate; a plurality of lifting components 2 mounted on the bracket 1, each lifting component 2 including a threaded lifting unit mounted on the bracket 1 and whose movable end is connected to a bottle-laying platform; and a centering support component connected to the threaded lifting unit for receiving the gear ring 3, wherein the driving end of the threaded lifting unit is fixed with a driven gear 8 that meshes with the gear ring 3.

[0025] The support 1 includes a horizontal support and a vertical support, which are connected to form a support platform. Support legs are installed at the bottom of the support platform. The lifting component 2 extends through the support platform so that the gear ring 3 and the driving component are located below the support platform, thereby reducing the distance between the bottle-placement platform and the support 1 and improving the stability of the lifting mechanism.

[0026] In this embodiment, the toothed ring 3 is effectively supported by the centering support, so that the toothed ring 3 is suspended in the air. At the same time, the lifting component 2 is installed through the bracket 1, so that there is no support platform below the toothed ring 3. This eliminates the problem of water accumulation on the support platform when cleaning the bottle.

[0027] The multiple threaded lifting units are connected to the gear ring 3 via driven gear 8. When the gear ring 3 rotates, the lifting of multiple lifting components 2 can be synchronized, ensuring the synchronization and stability of the bottle-laying platform. The design of the centering support not only achieves effective support for the gear ring 3, but also ensures the stability of the gear ring 3 during rotation, thereby further improving the stability and reliability of the cleaning process.

[0028] Further, please refer to Figure 1 , Figure 2 and Figure 5 The threaded lifting unit includes: a threaded sleeve 204 rotatably mounted on the bracket 1, a threaded sleeve 203 fixed inside the threaded sleeve 204, and the drive end formed by fixing the driven gear 8 on the threaded sleeve 204; a screw 202 passing through the threaded sleeve 203 and extending into the threaded sleeve 204, and threadedly connected to the threaded sleeve 203, the end of the screw 202 away from the threaded sleeve 204 forming the movable end, wherein: the threaded sleeve 204 passes through the bracket 1 and is connected to the first bearing seat 9 and the second bearing seat 10 installed at the upper and lower ends of the bracket 1.

[0029] The through-hole threaded sleeve 204, in conjunction with the first bearing seat 9 and the second bearing seat 10, can effectively improve the stability during the rotation of the threaded sleeve 204, ensuring the stability and synchronization of the lifting action.

[0030] Specifically, when the gear ring 3 rotates, it drives multiple driven gears 8 to rotate synchronously. When the driven gears 8 rotate, they drive the threaded sleeve 204 to rotate. The threaded sleeve 204 drives the lead screw 202 to move along its axial direction through the screw sleeve 203 fixed to it, thereby realizing the vertical lifting and lowering drive of the bottle-laying platform. Under the rotation of the gear ring 3, the multiple driven gears 8 can maintain synchronous rotation, thus ensuring the coordination and stability of the entire lifting system, and can bear a large load, ensuring the stability and safety of the bottle-laying platform during the lifting process.

[0031] Further, please refer to Figures 3-5 The centering support includes a centering seat 6 mounted on the frame 1 and a centering component 7 fixedly mounted on the centering seat 6. The centering component 7 and the driven gear 8 form a receiving space for inserting the gear ring 3.

[0032] For preferred options, please refer to [link / reference]. Figure 6 In one embodiment, the centering component 7 includes a connecting shaft 701 fixed on the centering seat 6 and a nylon wheel 702 sleeved on the connecting shaft 701 and having an "I"-shaped cross section along the axial direction. It also includes a fixing component 703 for fixing the nylon wheel 702 to the connecting shaft 701. The fixing component 703 can be fixed to the connecting shaft 701 by an interference fit.

[0033] Thus, when the gear ring 3 is placed in the receiving space, its inner wall is in contact with the outer wall of the annular inner insert of the multiple centering components 7, achieving precise positioning of the gear ring 3. This not only improves the stability of the gear ring 3 during rotation but also effectively reduces noise and wear caused by shaking or offset, extending the service life of the equipment. At the same time, the setting of the centering support component also makes the installation and disassembly of the gear ring 3 simpler and faster, improving the maintenance efficiency of the equipment.

[0034] Preferably, a protective cover 201 is fitted around the lead screw 202 located between the bottle placement platform and the support 1, thereby effectively preventing the lead screw 202 from directly contacting external objects during the lifting and lowering process, reducing damage caused by collision or friction, and improving the service life of the lead screw 202. At the same time, the retractable design of the protective cover 201 allows it to extend or retract accordingly with the lifting and lowering of the lead screw 202, always maintaining full protection for the lead screw 202, eliminating the need for frequent manual adjustments, and saving manpower and time.

[0035] Preferably, in one embodiment, the sheath 201 is a retractable rubber sleeve or two sleeves fitted together, one sleeve being fixed on the first bearing seat 9, and the other sleeve being fixed on the screw connecting seat (used to connect the screw 202 and the bottle-laying platform) which is fixed to the bottle-laying platform.

[0036] The aforementioned driving component includes a motor 4 mounted on the bracket 1 via a motor mount. The output shaft of the motor 4 is fixed with a drive gear 5 that meshes with the gear ring 3. The motor 4 drives the drive gear 5 to rotate, thereby causing the gear ring 3 to rotate, thus fulfilling the driving requirements.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
