Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a capping device for chemical reagent packaging bottles. Background Technology

[0002] A capping device is a device used to seal a container. A capping device for chemical reagent packaging bottles is a device specifically designed for sealing chemical reagent packaging bottles. In a broad sense of container sealing, the sealing material can be a stopper, gasket, etc. The part of the container that uses the sealing material is called the bottle mouth. The cap is usually the most critical part of the packaging. In addition to being easy to open and (if applicable) to be re-closed, it must also meet all the basic functions of the packaging.

[0003] In existing technologies, especially when using a capping device to cover chemical reagent packaging bottles with a stopper, it is necessary to apply downward pressure to cover the packaging bottle. However, when dealing with packaging bottles of various heights, the limiting structure on the device cannot adjust the height, making it difficult to limit packaging bottles of various heights using the existing limiting structure. This has certain limitations in use. If a limiting structure is not used, the packaging bottle may accidentally shift or tip over before capping, affecting the accuracy of capping. Utility Model Content

[0004] This utility model provides a capping device for chemical reagent packaging bottles, which facilitates capping operations on packaging bottles of various heights, reduces usage limitations, and ensures capping accuracy.

[0005] In order to solve the problems of the prior art, this utility model discloses a capping device for chemical reagent packaging bottles, including a body and a capping head, wherein the capping head is located in the upper part of the body;

[0006] Below the sealing head is a sealing platform. The upper part of the sealing platform is fixed with a lower annular positioning sleeve around the perimeter. The upper part of the lower annular positioning sleeve is provided with an upper annular positioning sleeve. The inner walls of the lower annular positioning sleeve and the upper annular positioning sleeve are provided with elastic clamping components.

[0007] An electric telescopic shaft is fixed to one side of the upper end of the lower annular positioning sleeve, and the power end of the electric telescopic shaft is fixed to the adjacent upper annular positioning sleeve above.

[0008] A protective box is located below the packaging platform, and a material changing drive assembly is located inside the protective box.

[0009] Furthermore, each of the elastic clamping components includes a limiting protrusion and a spring. The inner walls of the lower annular positioning sleeve and the upper annular positioning sleeve are all provided with shrinkage grooves. The limiting protrusions are slidably connected to the shrinkage grooves, and the ends of the limiting protrusions extend out of the shrinkage grooves. One end of the spring is connected to the inner wall of the shrinkage groove, and the other end of the spring is fixed to the limiting protrusion.

[0010] Furthermore, the limiting protrusion is hemispherical.

[0011] Furthermore, the inner diameter of the lower annular positioning sleeve is equal to that of the upper annular positioning sleeve.

[0012] Furthermore, a telescopic rod is fixed to the other side of the upper end of the lower annular positioning sleeve, and the upper end of the telescopic rod is fixed to the adjacent upper annular positioning sleeve.

[0013] Furthermore, the material changing drive assembly includes a support shaft, a brake motor, a PLC controller, a main gear, and a secondary gear. The support shaft is rotatably connected to the bottom of the protective box and rotatably extends through the top of the protective box. The packaging platform is fixed to the upper end of the support shaft.

[0014] Furthermore, both the brake motor and the PLC controller are fixed inside the protective box. The main gear is connected to the power end of the brake motor, and the auxiliary gear is fixedly sleeved around the support shaft, and the auxiliary gear meshes with the main gear.

[0015] Furthermore, the front end of the protective box is covered with a cover plate that is fixed by bolts.

[0016] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0017] 1. By setting up elastic clamping components, it is easy to quickly clamp and limit the packaging bottles of various outer diameters. The lower ring positioning sleeve limits the lower part of the packaging bottle and the upper ring positioning sleeve limits the upper part of the packaging bottle. Therefore, it helps to prevent the packaging bottle from shifting or tipping before sealing, thus ensuring the accuracy of sealing the packaging bottle.

[0018] 2. The extension and retraction of the electric telescopic shaft facilitates the up and down movement of the upper annular positioning sleeve, thus allowing for adjustment of the distance between the upper and lower annular positioning sleeves and the limiting height of the upper annular positioning sleeve. This facilitates the limiting of packaging bottles of various heights and effectively reduces the limitations of capping.

[0019] 3. By setting four sets of lower and upper annular positioning sleeves on the packaging platform, and combining the operation of the material changing drive component to drive the packaging platform to rotate, it is convenient to quickly change to the next packaging bottle for capping, thereby improving the capping efficiency.

[0028] A sealing device for chemical reagent packaging bottles:

[0029] like Figure 1 , 2As shown in Figures 4 and 5, this embodiment includes a body 1 and a sealing head 2. The sealing head 2 is located in the upper part of the body 1. A sealing platform 3 is provided below the sealing head 2. Lower annular positioning sleeves 5 are fixed around the upper end of the sealing platform 3. Upper annular positioning sleeves 6 are provided at the upper end of each lower annular positioning sleeve 5. Elastic clamping components are provided around the inner walls of both the lower annular positioning sleeve 5 and the upper annular positioning sleeve 6. Each elastic clamping component includes a limiting protrusion 9 and a spring 11. Shrinkage grooves 10 are opened around the inner walls of both the lower annular positioning sleeve 5 and the upper annular positioning sleeve 6. The limiting protrusions 9 are slidably connected to the shrinkage grooves 10, and the ends of the limiting protrusions 9 extend out of the shrinkage grooves 10. One end of the spring 11 is connected to the inner wall of the shrinkage groove 10, and the other end of the spring 11 is fixed to the limiting protrusion 9. The limiting protrusion 9 is hemispherical. The inner diameters of the lower annular positioning sleeve 5 and the upper annular positioning sleeve 6 are equal.

[0030] By setting up an elastic clamping component, the packaging bottle is inserted from top to bottom into the upper annular positioning sleeve 6 and the lower annular positioning sleeve 5. During this process, the packaging bottle will push the limiting protrusion 9 into the shrinkage groove 10 along the arc surface of the hemispherical limiting protrusion 9. The limiting protrusion 9 compresses the spring 11. After the packaging bottle is fully inserted, the elastic force of the spring 11 applies a reaction force to the limiting protrusion 9, which is conducive to quickly clamping and limiting packaging bottles of various outer diameters. The lower annular positioning sleeve 5 limits the lower part of the outer periphery of the packaging bottle, and the upper annular positioning sleeve 6 limits the upper part of the outer periphery of the packaging bottle. During the process of the capping head 2 on the machine body 1 sealing the packaging bottle with the stopper (the working principle of the capping head 2 sealing the packaging bottle with the stopper is existing technology and is not a technical improvement point in this case, so it will not be described in detail), it is beneficial to prevent the packaging bottle from shifting or tipping before sealing, thereby ensuring the accuracy of the packaging bottle sealing.

[0031] like Figure 2 As shown, in this embodiment, an electric telescopic shaft 7 is fixed on one side of the upper end of the lower annular positioning sleeve 5, and the power end of the electric telescopic shaft 7 is fixed to the adjacent upper annular positioning sleeve 6.

[0032] The extension and retraction of the electric telescopic shaft 7 facilitates the up-and-down movement of the upper annular positioning sleeve 6, thereby facilitating the adjustment of the distance between the upper annular positioning sleeve 6 and the lower annular positioning sleeve 5. This allows for easy adjustment of the limiting height of the upper annular positioning sleeve 6, which in turn helps to limit the positioning of packaging bottles of various heights, preventing positional shifts or tipping of the packaging bottles before capping and effectively reducing the limitations of capping.

[0033] like Figure 2 As shown in this embodiment, a telescopic rod 8 is fixed on the other side of the upper end of the lower annular positioning sleeve 5, and the upper end of the telescopic rod 8 is fixed to the adjacent upper annular positioning sleeve 6.

[0034] By setting the telescopic rod 8, when the upper annular positioning sleeve 6 moves up and down, it will pull the telescopic rod 8 to extend and retract together. Since the telescopic rod 8 is located on the other side, it plays a role in providing auxiliary support for the upper annular positioning sleeve 6, which helps to ensure the stability of the upper annular positioning sleeve 6's up and down movement.

[0035] like Figure 1 , 3 As shown, in this embodiment, a protective box 4 is provided below the packaging platform 3. A material changing drive assembly is provided inside the protective box 4. The material changing drive assembly includes a support shaft 12, a brake motor 13, a PLC controller 16, a main gear 14, and a secondary gear 15. The support shaft 12 is rotatably connected to the bottom of the protective box 4 and rotatably extends through the top of the protective box 4. The packaging platform 3 is fixed to the upper end of the support shaft 12. The brake motor 13 and the PLC controller 16 are both fixed inside the protective box 4. The main gear 14 is connected to the power end of the brake motor 13. The secondary gear 15 is fixedly sleeved around the support shaft 12 and meshes with the main gear 14.

[0036] By setting four sets of lower annular positioning sleeves 5 and upper annular positioning sleeves 6 on the packaging platform 3, with each set of lower annular positioning sleeves 5 and upper annular positioning sleeves 6 holding one packaging bottle, and setting the PLC controller 16 to be electrically connected to the brake motor 13, the PLC controller 16 controls the brake motor 13 to work. When the brake motor 13 works, it drives the main gear 14, the secondary gear 15, the support shaft 12, the packaging platform 3, the lower annular positioning sleeves 5 and the upper annular positioning sleeves 6 to rotate 90 degrees each time and stop, which means that the corresponding packaging bottle is moved to the lower end of the capping head 2. Therefore, combined with the work of the material changing drive component to drive the packaging platform 3 to rotate, it is convenient to quickly change to the next packaging bottle for capping. After the capped packaging bottle is away from the packaging bottle, it can be safely taken out and replaced, thereby improving the capping efficiency.

[0037] like Figure 2 As shown, in this embodiment, the front end of the protective box 4 is covered with a cover plate 17 fixed by bolts.

[0038] By setting a cover plate 17 that can be installed and removed with bolts, the structure inside the protective box 4 can be easily maintained when there is a fault, thereby ensuring that the structure inside the protective box 4 works normally.

[0039] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
