A capping machine for reducing bottle body shaking during filling

Abstract

This utility model relates to a capping machine, specifically, a capping machine for filling bottles that reduces bottle sway. It includes an assembly table, with a pressing component mounted on its upper side. In its initial state, the wedges are housed within guide grooves, not occupying space on the upper side of the assembly table, thus facilitating bottle placement. During capping, a servo cylinder drives a moving plate and the wedges upwards. The interaction between the wedge's inclined surface and the fixed guide wheel forces all wedges to move synchronously towards the center. This, in turn, causes T-blocks to drive rubber pads to evenly clamp the bottle from all sides, securing it and suppressing sway during capping. Furthermore, when the moving plate moves downwards, the T-blocks are blocked from contacting the fixed cross plate, allowing the T-blocks to slide out of the T-grooves of the wedges. This facilitates quick disassembly and replacement of T-blocks of different sizes to accommodate the clamping needs of bottles with different shapes, ensuring a stable anti-sway effect for various bottle types.

Description

Technical Field

[0001] This utility model relates to a capping machine, specifically, to a capping machine for filling bottles that reduces bottle shaking. Background Technology

[0002] A capping machine is a device used to press a cap onto the bottle neck to complete the seal. During the capping process, in order to prevent poor sealing, liquid spillage, or even bottle breakage caused by the bottle tilting or tilting, it is necessary to effectively reduce the shaking of the bottle.

[0003] Common beverage bottles and medicine bottles are mostly cylindrical. In existing technology, fixed clamps or fixed-position clamps are usually used to hold the bottle from around the body in an attempt to suppress its shaking.

[0004] However, the fixed clamping mechanism protrudes from the workbench in its initial state, which not only occupies the operating space and affects the efficiency of convenient placement and removal of the bottle, but also these clamps are often custom-made for specific bottle types and lack versatility. When switching to bottles of different diameters or shapes, it is necessary to replace the entire complex clamping module, which is cumbersome to operate and takes a long time to adjust, thus affecting the flexibility and efficiency of production. Utility Model Content

[0005] The purpose of this invention is to provide a capping machine for filling bottles that reduces bottle shaking, thereby solving the problems mentioned in the background art.

[0006] To address the above problems, the present invention aims to provide a capping machine for filling bottles that reduces bottle shaking. The machine includes an assembly table, a pressing assembly on its upper side, several guide grooves on the assembly table, a support frame fixedly mounted on its lower side wall, and a servo cylinder fixedly mounted on the bottom of the support frame. The upper end of the push rod of the servo cylinder slides through the support frame and is fixedly mounted with a moving plate. A clamping block assembly is provided on the upper side of the moving plate at a position corresponding to each guide groove. The clamping block assembly includes a wedge slidably mounted on the moving plate, located inside the corresponding guide groove. The clamping block assembly also includes a displacement mechanism for driving the wedge to slide along the inner wall of the guide groove. When the servo cylinder drives the moving plate to move vertically upward, the moving plate drives the wedge to move upward, and simultaneously, the displacement mechanism drives the wedge to move towards the center of the assembly table.

[0007] As a further improvement to this technical solution, the displacement mechanism includes two end plates fixedly installed on the side wall of the movable plate, two guide rods fixedly installed between the two end plates, and the wedge block slidably installed on the two guide rods.

[0008] As a further improvement to this technical solution, a return spring is sleeved on the guide rod. The two ends of the return spring are fixedly connected to the side of the wedge block near the center of the assembly table and the end plate, respectively. The return spring is used to push the wedge block away from the center of the assembly table.

[0009] As a further improvement to this technical solution, the displacement mechanism also includes a wheel frame fixedly installed inside the guide groove. Several guide wheels are equidistantly mounted on the wheel frame along the inclined direction. The guide wheels roll in contact with the side of the wedge block away from the center of the assembly table, and the side of the wedge block in contact with the guide wheels is set as an inclined surface.

[0010] As a further improvement to this technical solution, a T-shaped groove is provided on the side of the wedge block near the center of the assembly table, and a T-shaped block is slidably installed inside the T-shaped groove. One end of the T-shaped block extends to the outside of the T-shaped groove and is fixedly installed with a rubber pad.

[0011] As a further improvement to this technical solution, a cross plate is fixedly installed on the lower side wall of the assembly table, and the ends of the cross plate extend to the bottom of the four T-blocks respectively.

[0012] As a further improvement to this technical solution, when the servo electric cylinder drives the moving plate to move downward, the lower sidewall of the T-block contacts the upper sidewall of the cross plate.

[0013] As a further improvement to this technical solution, the pressing assembly includes a mounting plate installed on the upper side of the assembly platform. A cylinder is fixedly installed on the upper side wall of the mounting plate, and the lower end of the piston rod of the cylinder slides through the mounting plate and is fixedly installed with a pressure head.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This capping machine for filling bottles reduces bottle sway. In its initial state, the wedges are stored inside the guide grooves, not occupying space on the upper side of the assembly table, thus facilitating bottle placement. During the capping process, the moving plate and wedges are moved upward by a servo electric cylinder. The interaction between the inclined surface of the wedges and the fixed guide wheels forces all wedges to move synchronously towards the center. Then, the T-blocks drive the rubber pads to clamp the bottle evenly from all sides, thus fixing the bottle and suppressing bottle sway during capping. When the moving plate moves downward, the T-blocks are blocked from contacting the fixed cross plate, allowing the T-blocks to slide out of the T-slots of the wedges. This facilitates quick disassembly and replacement of T-blocks of different sizes to meet the clamping requirements of bottles with different shapes, ensuring a stable anti-sway effect for various bottle types.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 Please see Figure 1 and Figure 2As shown, the purpose of this embodiment is to provide a capping machine for filling bottles that reduces bottle shaking. It includes an assembly table 1, and a pressing component 2 is provided on the upper side of the assembly table 1. The pressing component 2 is used to press the bottle cap stably and fix it to the bottle body. The structure of the pressing component 2 is detailed below. The pressing component 2 includes a mounting plate 21 installed on the upper side of the assembly table 1. Specifically, two slide rods are vertically fixedly installed on the upper side wall of the assembly table 1. The mounting plate 21 is slidably sleeved on the two slide rods. A crossbeam is fixedly installed on the upper end of the two slide rods. A threaded rod is rotatably installed on the crossbeam. The threaded rod is threadedly connected to the mounting plate 21. By rotating the threaded rod, the mounting plate 21 can be moved up and down along the slide rods, thereby adjusting the height of the entire pressing component 2 to adapt to the capping requirements of bottles of different heights.

[0019] A cylinder 22 is fixedly installed on the upper side wall of the mounting plate 21. The lower end of the piston rod of the cylinder 22 slides through the mounting plate 21 and is fixedly installed with a pressure head 23. During operation, the operator or an external robot places the cylindrical bottle body with the bottle cap already placed on the bottle mouth on the assembly table 1, and ensures that the bottle cap is directly below the pressure head 23. Then, the cylinder 22 is activated, and the piston rod pushes the pressure head 23 down to press the bottle cap tightly onto the bottle body.

[0020] To reduce bottle shaking during capping, several vertically penetrating guide grooves 11 are provided on the assembly table 1. All guide grooves 11 are arranged in a circular array with the axis of the pressure head 23 as the center, as shown in the figure. Figures 3-9 A support frame 3 is fixedly installed on the lower side wall of the assembly table 1. A servo cylinder 4 is fixedly installed at the bottom of the support frame 3. The upper end of the push rod of the servo cylinder 4 slides through the support frame 3 and is fixedly installed on a moving plate 5. A clamping block assembly 7 is provided on the upper side of the moving plate 5 at a position corresponding to each guide groove 11. The clamping block assembly 7 includes a wedge 73 slidably installed on the moving plate 5. The wedge 73 is located inside the corresponding guide groove 11. A T-shaped groove 731 is opened on the side of the wedge 73 near the center of the assembly table 1. A T-shaped block 77 is slidably installed inside the T-shaped groove 731. One end of the T-shaped block 77 extends to the outside of the T-shaped groove 731 and is fixedly installed with a rubber pad 78.

[0021] In the initial state, the upper end of the wedge 73 is housed inside the guide groove 11, ensuring that the upper side of the assembly table 1 is clean and easy to place the bottle.

[0022] The clamping block assembly 7 also includes a displacement mechanism for driving the wedge block 73 to slide along the inner wall of the guide groove 11. After the bottle body is placed on the assembly table 1 at the position between all the rubber pads 78, the moving plate 5 is driven to move vertically upward by the servo electric cylinder 4. The moving plate 5 drives the wedge block 73 to move upward, and at the same time, the displacement mechanism drives the wedge block 73 to move towards the center of the assembly table 1. The wedge block 73 drives the rubber pads 78 to move synchronously, so that all the rubber pads 78 move together synchronously and make tight contact with the outer wall of the bottle body, thereby clamping and fixing the bottle body to suppress the shaking of the bottle body during the capping process.

[0023] The following details the structure of the displacement mechanism, referring to... Figures 7-9 The displacement mechanism includes two end plates 71 fixedly mounted on the upper side wall of the movable plate 5. Two guide rods 72 are horizontally fixedly mounted between the two end plates 71. A wedge 73 is slidably mounted on the two guide rods 72, so that the wedge 73 can only move horizontally along the axis of the guide rods 72. A return spring 74 is sleeved on the guide rods 72. The two ends of the return spring 74 are fixedly connected to the side of the wedge 73 near the center of the assembly table 1 and the end plate 71, respectively. The return spring 74 is used to push the wedge 73 away from the center of the assembly table 1. The displacement mechanism also includes a wheel frame 75 fixedly mounted inside the guide groove 11. Several guide wheels 76 are equidistantly mounted on the wheel frame 75 along the inclined direction. The guide wheels 76 roll in contact with the side of the wedge 73 away from the center of the assembly table 1, and the side of the wedge 73 in contact with the guide wheel 76 is set as an inclined surface.

[0024] When the servo cylinder 4 pushes the moving plate 5 upward, the wedge 73 rises accordingly. During the upward movement, the inclined surface of the wedge 73 contacts and rolls with the guide wheel 76, causing the wedge 73 to overcome the elastic force of the return spring 74 and move towards the center of the assembly table 1. The return spring 74 is thus compressed and contracted. The movement of the wedge 73 then drives the rubber pad 78 to move towards the center through the T-block 77, finally clamping the bottle body.

[0025] After the capping is completed, the servo electric cylinder 4 drives the moving plate 5 to move down, which in turn moves the wedge 73 down. At the same time, the reset spring 74 rebounds, pushing the wedge 73 away from the bottle body and returning it to its initial position, thereby releasing the clamping of the rubber pad 78 on the bottle body. At this time, the bottle body can be removed.

[0026] To accommodate the clamping requirements of bottles with different shapes, a cross plate 6 is fixedly installed on the lower side wall of the assembly table 1. The ends of the cross plate 6 extend to the bottom of the four T-blocks 77. When the servo cylinder 4 drives the moving plate 5 to move downward, the moving plate 5 drives the wedge block 73 and the T-block 77 to move downward synchronously. The lower side wall of the T-block 77 contacts the upper side wall of the cross plate 6. If the moving plate 5 continues to move downward, since the cross plate 6 is fixed, it will prevent the T-block 77 from moving downward with the wedge block 73, causing relative movement between the T-block 77 and the wedge block 73, so that the T-block 77 slides out of the T-groove 731 of the wedge block 73, thereby realizing the quick disassembly of the T-block 77.

[0027] Next, the operator can replace the T-block 77 with one of the appropriate size according to the shape of the bottle to ensure that all rubber pads 78 can effectively clamp the bottle when the wedge 73 moves the T-block 77 toward the center, thereby expanding the applicability of the device.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
