Description

Technical Field

[0001] The present application relates to the field of liquid food filling production with lids, and in particular to a rectangular channel with adjustable length. Background Art

[0002] In the production of beer and carbonated beverage filling, the filled products need to be sealed, which requires various caps, such as plastic caps, crown caps, etc. After the cap sorting process, these caps will be arranged in the same direction, waiting for the sealing station to take the caps and add them to the bottles to complete the sealing of the bottles. In order to achieve batch industrial production, the arranged caps are usually designed with a certain buffer volume, which requires a rectangular channel to transport the caps and also serve as a buffer. In order to ensure continuous and stable cap transportation, this rectangular channel is usually made of non-soft materials.

[0003] In actual engineering applications, bottles have different heights, and one device needs to seal bottles of different heights in different time periods. A commonly used technology is to design the rectangular channel for conveying caps into multiple sections, and then design a certain section in the middle to be replaceable. Each bottle of a certain height corresponds to a rectangular conveying section of a certain length. When the equipment needs to seal bottles of another height, the replaceable rectangular conveying section is disassembled and replaced with a section of the corresponding length to adapt to the sealing of this type of bottle.

[0004] However, there are two prominent problems with manual replacement. The first is that each time you switch to a different height, you need to dismantle it first and then install it. After installation, it may also take a period of adjustment, which takes a considerable amount of time and affects efficiency. The second is that each time you make manual adjustments, due to differences in skills and work concentration, as well as the decrease in positioning accuracy after multiple disassembly and replacement, there will be more or less a period of adjustment due to the cap jam after replacement. This jam will cause the filled products in production to not be sealed in time, affecting product quality and causing a certain amount of scrapping. Especially for large-capacity equipment, dozens of bottles of uncapped products may be rejected each time the cap jams.

[0005] If there is a way to automatically adjust the length of the rectangular cap conveying channel when producing bottles of different heights, it will greatly save changeover time and quality, which is a pain point in improving quality and efficiency.

[0006] At present, relevant patents have been retrieved for the above-mentioned problems, such as CN208150257U, CN210619313U and CN215796705U, which are close to the present application. However, the contents of the patents cannot provide corresponding solutions to the background technology content, and the contents of other patents cannot provide corresponding solutions either, so there is no effective way to solve the above-mentioned problem.

It is understood that the drawings are only provided for reference and illustration, and are not used to limit the present application. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.

[0033] Specifically, Figure 1 As shown, a rectangular channel with adjustable length is provided in an embodiment of the present application, and the cross-section of the channel is set to a rectangular shape to facilitate the limited transportation of the bottle caps. At the same time, in order to facilitate transportation, a first channel 100 and a second channel 200 are provided in the present application, and the first channel 100 and the second channel 200 are connected, and a transition area is provided between the first channel 100 and the second channel 200 to facilitate the transportation of the bottle caps.

[0034] Specifically:

The first guide rail 110 and the second guide rail 120 are arranged opposite to each other, and the first guide rail 110 and the second guide rail 120 are arranged in parallel, so that the first guide rail 110 and the second guide rail 120 enclose and form the first channel 100.

[0036] Among them, the first guide rail 110 and the second guide rail 120 are both in a C-shaped structure, so that the cross-section of the first channel 100 presents a rectangular structure. In the rectangular structure, an abutment bar 150 is provided. The abutment bar 150 is a protruding long strip structure on the first guide rail 110 and the second guide rail 120 toward the first channel 100. The abutment bar 150 can abut against both sides of the bottle cap to limit the bottle cap for the first time, thereby facilitating the transportation of the bottle cap.

[0037] Preferably, in the embodiment of the present application, since the thicknesses of different bottle caps are different, the abutment bar 150 can be set as a spring structure, and a spring is provided between the abutment bar 150 and the first guide rail 110 and the second guide rail 120 to adapt to the sizes of different bottle caps and facilitate the limiting of the bottle caps.

[0041] Through the first channel 100 and the second channel 200, and the cross-sectional area of ​​the second channel 200 is smaller than the cross-sectional area of ​​the first channel 100, the bottle cap can enter the second channel 200 from the first channel 100, and the second channel 200 further limits the bottle cap to facilitate the transportation of the bottle cap.

[0042] To facilitate the positioning of the bottle cap, an abutment member 140 is connected between the first guide rail 110 and the second guide rail 120 , and both ends of the abutment member 140 abut against the first guide rail 110 and the second guide rail 120 , respectively, so that a first channel 100 is formed between the first guide rail 110 and the second guide rail 120 .

[0043] The abutment member 140 is configured as a buffer pad in the present application, and the buffer pad is sandwiched between the first guide rail 110 and the second guide rail 120, so that a rectangular channel is formed between the first guide rail 110 and the second guide rail 120;

[0044] In the present application, two groups of buffer pads are provided, each group is provided with two, one group is a square buffer pad, and the buffer pad is fixed by screws on the first connecting member 130, and at the same time, the screws pass through the first guide rail 110 and the second guide rail 120 to limit the first guide rail 110 and the second guide rail 120, so that the first guide rail 110 and the second guide rail 120 can be finely adjusted in distance through the group of buffer pads;

[0045] Another set of buffer pads is a buffer roller, which can cooperate with the square buffer pad to buffer the first guide rail 110 and the second guide rail 120;

[0046] Preferably, in the embodiment of the present application, the buffer roller can also assist the movement of the second channel 200 so as to adjust the transition area between the first channel 100 and the second channel 200.
