A bottle capping mechanism of a capping machine

Abstract

This utility model relates to the field of capping machine technology, specifically a bottle capping mechanism for a capping machine. It includes a cabinet with a conveyor running horizontally across its top. Two sets of positioning plates are symmetrically arranged on the top of the conveyor, and a capping device is positioned above the conveyor. A frame is fixed to one side of the capping device on the top of the cabinet. A screening mechanism for removing bottles with loose caps is located below the frame, along with an adjusting component to drive the screening mechanism upwards or downwards. This utility model incorporates a screening mechanism. For defective bottles, when they move to the mounting plate, the caps of these bottles, being relatively high, will touch a pressure sensor and be temporarily blocked. Simultaneously, the pressure sensor rapidly transmits a signal to an electric push rod. The electric push rod, through a push block, quickly pushes the defective bottle out of the notch, thus screening it out and ensuring overall product quality.

Description

Technical Field

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

[0002] Patent application number 202421627562.4 discloses a capping machine for pure water production. Bottle caps are conveyed into a chute and flow to the bottom of the chute, where they are held in place by a pressure plate. When the cap slides to the bottom of the chute, it is tilted with its bottom opening facing left. Water bottles are moved from the left by a conveyor belt. When the bottle reaches the bottom of the chute, the top of the bottle slightly passes the left end of the cap and abuts against the inner right side of the cap, thus pulling the cap out. This simple operation greatly improves capping efficiency. Subsequently, three conveyor belts transport and fix the water bottles, and the capping belts press the caps step by step, making the caps more tightly sealed and less prone to damage. However, after capping, some caps may bounce upwards due to elasticity or quality issues, resulting in incomplete capping. In this case, defective bottles need to be rejected to ensure the overall quality of the product. Based on this, a bottle capping mechanism for a capping machine is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a bottle capping mechanism for a capping machine, which can screen out bottles with loose caps and ensure the overall quality of the products.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a bottle capping mechanism for a capping machine, comprising a cabinet, a conveyor running horizontally across the top of the cabinet, two sets of positioning plates symmetrically arranged on the top of the conveyor, and a capping device arranged above the conveyor; a frame is fixed on one side of the capping device at the top of the cabinet, and a screening mechanism for removing bottles with unpressed caps is arranged below the frame, as well as an adjusting component for driving the screening mechanism to move up or down; The screening mechanism includes a notch on a positioning plate and a connecting plate. An installation plate is fixed to the end of the connecting plate, and a pressure sensor is installed on the side of the installation plate. A support plate is fixed to the top of the conveyor, and an electric push rod is installed on the support plate. The electric push rod is connected to the pressure sensor, and a push block is fixed to the movable end of the electric push rod. When the bottle cap contacts the pressure sensor, the electric push rod controls the push block to push the bottle out of the notch.

[0005] Preferably, the adjusting component includes a first component, which is a hydraulic rod mounted on the frame, with the movable end of the hydraulic rod fixedly connected to the top of the mounting plate.

[0006] Preferably, the adjusting component includes a second component, which includes a lead screw threaded onto the frame, the bottom of the lead screw being rotatably connected to the top of the mounting plate, and a limiting rod that is slidably connected to the frame being fixed to the top of the mounting plate.

[0008] Preferably, the outer end of the pusher is configured as an arc-shaped surface that adapts to the surface of the bottle.

[0009] Preferably, the edges of the positioning plates are bent outwards so that the bottle can smoothly enter between the two sets of positioning plates.

Detailed Implementation

[0014] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Example

[0015] After capping, some bottle caps may pop upwards due to elasticity or quality issues, meaning they are not completely sealed. To identify these bottles, the following solution has been implemented. Figures 1-4 As shown, a bottle capping mechanism for a capping machine includes a cabinet 1. A conveyor 2 runs horizontally across the top of the cabinet 1. Two sets of positioning plates 4 are symmetrically arranged on the top of the conveyor 2. The edges of the positioning plates 4 are bent outwards to allow the bottle to smoothly enter between the two sets of positioning plates 4. The positioning plates 4 ensure that the bottle moves in a straight line, allowing the bottle and cap to move smoothly to the position below the capping device 3. The capping device 3 is arranged above the conveyor 2 (the capping device 3 is an existing mature technology, which will not be elaborated here, but can be referred to the patent with application number 202421627562.4). A frame 5 is fixed on one side of the capping device 3 at the top of the cabinet 1. A screening mechanism 6 for removing bottles with loose caps is arranged below the frame 5, and a first piece 7 drives the screening mechanism 6 to move up or down. The bottle cap is placed on the bottle body, either manually or via a slide mechanism. Under the constraint of two sets of positioning plates 4, it moves along the conveyor 2 to the capping device 3. After capping, it passes through the screening mechanism 6. Compared to a tightly sealed cap, an unsealed cap is too high. The screening mechanism 6 can intercept it and remove it from between the two sets of positioning plates 4.

[0016] To successfully remove loosely capped bottles, the screening mechanism 6 includes a notch 67 on the positioning plate 4, the size of which is larger than the outer diameter of the bottle, and a connecting plate 61. A mounting plate 62 is fixed to one end of the connecting plate 61, and a pressure sensor 63 is mounted on the side of the mounting plate 62. A support plate 64 is fixed to the top of the conveyor 2 on the side away from the notch 67. An electric push rod 65 is mounted on the support plate 64, and the electric push rod 65 is signal-connected to the pressure sensor 63. A push block 66 is fixed to the movable end of the electric push rod 65, and the outer end of the push block 66 is designed with an arc-shaped surface adapted to the bottle surface. When the bottle cap contacts the pressure sensor 63, the electric push rod 65 controls the push block 66 to push the bottle (the bottle with the loosely capped bottle) out of the notch 67.

[0017] During use, for bottles with loose caps (referred to as "abnormal bottles"), the height of the abnormal bottle is greater than that of a normal bottle (with a tightly closed cap). When the abnormal bottle moves to the position of the mounting plate 62, its cap, being taller, will touch the pressure sensor 63 and be temporarily blocked. At the same time, the pressure sensor quickly transmits a signal to the electric push rod 65, which extends rapidly, driving the push block 66 to move. The push block 66 can quickly push the abnormal bottle out through the notch 67, thus screening out the abnormal bottle and ensuring the overall quality of the product. After the abnormal bottle is pushed out, the pressure sensor 63 loses pressure, and the electric push rod 65 retracts rapidly, causing the push block 66 to return to its original position.

[0018] To better fit the bottle cap surface and adapt to the capping screening of bottles of various heights, the following solution is provided: The first component 7 is a hydraulic rod installed on the frame 5, and the movable end of the hydraulic rod is fixedly connected to the top of the mounting plate 62.

[0019] During use, based on the specific height of the bottle cap of a normal bottle, the hydraulic rod drives the connecting plate 61 to move, thereby moving the mounting plate 62 and its pressure sensor 63 close to the surface of the bottle cap, but without making contact, to ensure the smooth passage of normal bottles. For bottles with unusual heights, they can be easily screened out. It can adapt to screening normal bottles of different heights and has good practicality.

[0020] To move bottles of different sizes along the same straight line to the capping device 3, the following solution is provided: Several sets of connecting plates 9 are fixed on the top two sides of the conveyor 2. A sleeve 10 is fixed on the end face of the connecting plate 9. A telescopic rod 11 is slidably installed inside the sleeve 10. The end of the telescopic rod 11 extends out of the sleeve 10 and is fixed to the corresponding positioning plate 4. A locking screw 12 for locking the telescopic rod 11 is installed on the outer end of the sleeve 10.

[0021] When using it, taking a small bottle as an example, loosen the locking screw 12, pull the positioning plates 4 on both sides inward until the positioning plates 4 on both sides are close to the outer wall of the bottle, and then tighten the locking screw 12. Example

[0022] Basically the same as in Example 1, such as Figures 5-6 As shown, the difference is that the second part 8 includes a lead screw 81 threadedly mounted on the frame 5. The bottom of the lead screw 81 is rotatably connected to the top of the mounting plate 62. The top of the mounting plate 62 is fixed with a limiting rod 82 that is slidably connected to the frame 5.

[0023] In use, based on the specific height of the bottle cap of a normal bottle, the lead screw 81 is rotated. Under the constraint of the limit rod 82, this causes the mounting plate 62 and its pressure sensor 63 to move and approach the surface of the bottle cap, but not to make contact, ensuring the smooth passage of normal bottles. For bottles with unusual heights, they can be easily screened out. It can adapt to screening normal bottles of different heights and has good practicality.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
