Description

Technical Field

[0001] This utility model relates to the field of protection technology for bottle filling and capping integrated machines, and in particular to bottle filling and capping integrated machines with protective devices. Background Technology

[0002] In modern food, beverage, and pharmaceutical packaging industries, capping machines are widely used in high-speed production lines as key equipment for automatically capping and tightening bottles. Their front end typically uses a synchronous belt drive system for bottle conveying, offering advantages such as smooth operation, precise positioning, and easy maintenance. However, in actual production, a lack of impact resistance is a problem: Without effective limit or buffer structures on both sides of the synchronous belt, when the robotic arm malfunctions or there is a collision during manual operation, the bottles being conveyed in front will continue to move forward due to inertia, forming a "bottle stacking" phenomenon—multiple bottles are continuously squeezed, tilted, or even thrown off the conveyor belt, causing multiple losses; product quality is damaged: bottle scratches, labels are damaged; equipment downtime: manual intervention is required to clean up the collapsed bottles, with an average interruption of 5-10 minutes each time, which seriously affects OEE (Overall Equipment Efficiency).

[0003] To address these issues, we have proposed an integrated bottle filling and capping machine with a protective device. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a bottle filling and capping integrated machine with a protective device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A bottle-filling and capping machine with a protective device includes a capping machine body, a support frame fixed on one side of the capping machine body, mounting seats fixed on both sides of the upper end of the support frame, and a fixing seat fixed at one end of the mounting seat. Two guide rods are fixed on one side of the mounting base. Slider blocks are sleeved on the two guide rods. The upper ends of the two sliders are fixed to the bearing plate. An acrylic baffle is fixed on the bearing plate, and the two acrylic baffles correspond to each other. A hydraulic damper is fixed to one side of the mounting base, and a fixing plate is fixed to the other side of the mounting base. A hydraulic buffer is fixed to one end of the fixing plate. A moving block is connected between the piston rod of the hydraulic buffer and the hydraulic damper. The upper end of the moving block is fixed to the lower middle part of the bearing plate.

The hydraulic damper and hydraulic buffer are linked and combined to cover bidirectional motion, and the dual hydraulic systems are coordinated to achieve controllable damping throughout the entire stroke. 3.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-4 A bottle-filling and capping machine with a protective device includes a capping machine body 101. A support frame 102 is fixed on one side of the capping machine body 101. Mounting seats 501 are fixed on both sides of the upper end of the support frame 102. A fixing seat 504 is fixed on one end of the mounting seat 501. Two guide rods 302 are fixed on one side of the mounting base 501. A slider 503 is sleeved on the two guide rods 302. The two guide rods 302 and the matching slider 503 ensure the translational movement of the bearing plate. The upper ends of the two sliders 503 are jointly fixed to the support plate 403, and an acrylic baffle 401 is fixed on the support plate 403. The two acrylic baffles 401 correspond to each other. The acrylic baffles 401 have strong impact resistance and light transmittance ≥92%. A hydraulic damper 304 is fixed on one side of the mounting base 501, and a fixing plate 303 is fixed on the other side of the mounting base 501. A hydraulic buffer 301 is fixed at one end of the fixing plate 303. The resistance of the hydraulic buffer 301 can be adjusted within the range of 50–200N. A moving block 404 is connected between the piston rods of the hydraulic buffer 301 and the hydraulic damper 304. The upper end of the moving block 404 is fixed to the lower middle part of the bearing plate 403. The support frame 102 and the mounting base 501 adopt a quick-release flange interface with a positioning pin structure, which can complete the replacement of the entire set of protective components within 10 minutes and is suitable for different bottle diameters. A synchronous belt 103 is provided at the upper middle part of the support frame 102. The synchronous belt 103 is located between two acrylic baffles 401. The synchronous belt 103 adopts a high-precision synchronous toothed belt drive system, combined with servo motor closed-loop control, to ensure that the linear speed is stable and adjustable within the range of 0.5–2m / min, adapting to different bottle shapes (such as round, square, and irregularly shaped bottles). A fixed frame 202 is fixed to one side of the upper end of the support frame 102. A detector 201 is installed on the fixed frame 202. An acrylic baffle 401 passes through the fixed frame 202. The detector 201 adopts an industrial-grade CMOS global shutter camera with a resolution of more than 5 million pixels and a frame rate of ≥60fps. It is used in conjunction with a ring LED fill light to monitor information such as the number, posture, color, shape, and label integrity of bottles. The upper end of the fixed base 504 is provided with sliding grooves 502 on both sides. A slider 503 on the same side is engaged in a sliding groove 502 on the same side. Two mounting plates 402 are fixed on the upper end of the bearing plate 403. An acrylic baffle 401 on the same side is connected between the two mounting plates 402 by two bolts. One side of the acrylic baffle 401 is equipped with a wear-resistant coating. The wear-resistant coating is a nano-silica composite coating with a thickness of about 2–5 μm. The coefficient of friction is reduced to below 0.2. The coating can not only resist repeated scratches on the bottle, but also reduce static electricity to attract dust and extend the cleaning cycle.

[0017] In this utility model: 1. Normal operation phase: (1) Bottle conveying The bottle is fed in by the upstream equipment and moves forward along the synchronous belt 103 between two parallel acrylic baffles. The direction of travel is precisely guided by the baffles on both sides to prevent deviation. (2) Visual monitoring enabled The detector 201 (machine vision camera) is mounted on the mounting bracket 202. It monitors the number, spacing, posture and whether the bottles are overturned in real time through the transparent acrylic material. The signal is connected to the PLC control system. (3) The structure maintains static equilibrium The hydraulic buffer and damper are in a pre-compressed state, providing an initial preload (50N) to ensure that the load-bearing system is slightly compressed but not deformed, maintaining an overall rigid appearance.

[0018] (4) Abnormal event triggering stage (collision / bottle stacking) The dynamic buffer response phase will be initiated when any of the following occurs: blockage in subsequent processes leading to bottle accumulation; robot arm positioning deviation causing impact to the current bottle column; or manual accidental pushing of the front end of the bottle column. Step 1: The impact force is transmitted to the baffle. The front bottle row is pushed against the acrylic baffle 401 on one side by the force, and the force is transmitted step by step through the mounting plate 402 → bearing plate 403 → moving block 404. Step 2: Hydraulic system start-up buffer The moving block pulls the piston rod of the hydraulic damper 304 to extend, while simultaneously pushing the piston rod of the hydraulic buffer 301 to retract; the internal oil is forced to flow at high speed through the throttling orifice, converting kinetic energy into heat energy for consumption; because the oil circuit is designed as a bidirectional controllable damping system, it can generate constant resistance (adjustable within the range of 50–200N) whether in tension or compression, avoiding instantaneous overload and achieving millisecond-level energy absorption; Step 3: Guiding mechanism ensures motion accuracy The two guide rods 302 and the matching slider 503 ensure that the bearing plate only moves in a translational motion perpendicular to the production line direction. The design of the slide groove 502 to engage the slider prevents twisting or jamming and ensures that the baffles on both sides move synchronously. Step 4: Non-rigid relief protection for the bottle body The baffle is moved back horizontally by about 20-50mm to release the accumulated pressure, allowing the bottles to stretch out naturally and preventing them from stacking and tipping over. This process is like "soft wall yielding", which significantly reduces local stress concentration. Step 5: Automatic reset and resumption of operation Once the external force is removed, the hydraulic system, driven by built-in reverse oil pressure, slowly returns the bearing plate to its original position. The entire process requires no manual intervention, and the production line can be restarted immediately.

[0019] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
