Description

Technical Field

[0001] This utility model relates to the field of adhesive supply technology, and in particular to a fluid level monitoring and supply device. Background Technology

[0002] For two-component dispensing, existing dispensing machines typically use two independent feed screws to feed materials into the mixing tube (or mixing nozzle). The outlet of the mixing tube can be connected to a needle of any diameter to ensure accurate dispensing volume. Existing gear metering devices are completely inadequate for the requirements. When adhesive A and adhesive B enter the glue gun, the amount of adhesive dispensed determines the mixing ratio. Smaller dispensing ratios have a larger allowable error range, while larger ratios like 50:1 or 40:1 have a smaller allowable error range. Currently, dispensing devices cannot provide feedback on changes in the liquid level in the glue tank during two-component dispensing, thus making it impossible to control the dispensing volume and ratio, easily leading to adhesive imbalance. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a fluid level monitoring and supply device. This fluid level monitoring and supply device can avoid imbalance in the ratio of two-component adhesive, improve the quality of the final mixed adhesive, and also ensure the accuracy between the installation position and the push plate, avoiding the situation where adhesive cannot be pushed out due to positional deviation.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a fluid level monitoring and supply device, comprising: a glue tank having an A glue storage chamber and a B glue storage chamber respectively, and an A glue cylinder and a B glue cylinder corresponding to the A glue storage chamber and the B glue storage chamber respectively. The A glue cylinder and the B glue cylinder are disposed in a housing. The top of the glue tank has a protrusion, which has an A glue outlet communicating with the A glue storage chamber and a B glue outlet communicating with the B glue storage chamber respectively. A carrier block is installed on the upper surface of the top plate of the housing. At least two support columns are provided above the carrier block and a guide block connected to it. A contoured through hole that mates with the glue tank is opened on the upper surface of the carrier block. A guide through hole that mates with the protrusion on the glue tank is opened on the upper surface of the guide block. A first feed notch communicating with the contoured through hole and a second feed notch communicating with the guide through hole are respectively opened on the same side surface of the carrier block and the guide block.

[0005] The upper ends of the piston rods of the vertically arranged A-glue cylinder and B-glue cylinder are respectively equipped with A movable blocks and B movable blocks that can move vertically. The lower end of an A-glue push rod, coaxial with the A-glue storage cavity, is connected to the A movable block. The upper end of the vertically extending A-glue push rod passes through the top plate of the housing and is equipped with an A-glue push plate that is embedded in the A-glue storage cavity from the bottom. The lower end of a B-glue push rod, coaxial with the B-glue storage cavity, is connected to the B movable block. The upper end of the vertically extending B-glue push rod passes through the top plate of the housing and is equipped with a B-glue push plate that is embedded in the B-glue storage cavity from the bottom. The A-glue cylinder has one end connected to the piston rod of the A-glue cylinder and the B-glue cylinder. The other ends of the movable block and the B movable block extend toward the front side plate of the housing. The front side plate of the housing is provided with A-shaped holes and B-shaped holes extending in the vertical direction. An A indicator block located on the outside of the front side plate of the housing is connected to the end face of the A movable block away from the piston rod of the A-glue cylinder by a pin passing through the A-shaped hole. A B indicator block located on the outside of the front side plate of the housing is connected to the end face of the B movable block away from the piston rod of the B-glue cylinder by a pin passing through the B-shaped hole. Both the A indicator block and the B indicator block have an indicator part. An indicator barcode that cooperates with the indicator part is provided on the front surface of the front side plate of the housing.

[0006] The following are further improvements to the above technical solution:

[0007] 1. In the above scheme, there are 4 support columns, which are located at the four corners of the carrier block.

[0008] 2. In the above scheme, a rotating rod is provided between the two support columns located on both sides of the first feed notch. One end of the rotating rod is rotatably mounted on a support column, and the other end of the rotating rod is connected to a mounting block fixedly mounted on the support column by bolts.

[0009] 3. In the above scheme, a groove is provided on the rotating rod for another support column to be inserted.

[0010] 4. In the above scheme, the two indicator parts are arranged facing each other on opposite sides of indicator block A and indicator block B.

[0011] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

Both A and B-indicator blocks have an indicator section. An indicator barcode, cooperating with the indicator section, is provided on the front surface of the front side plate of the housing. This allows for real-time feedback on changes in the liquid level within the glue container during the two-component glue supply process, facilitating timely adjustment of the glue dispensing volume. To avoid imbalance in the two-component adhesive ratio and improve the quality of the final mixed adhesive, the top of the adhesive bucket has a protrusion with an A-component outlet communicating with the A-component storage chamber and a B-component outlet communicating with the B-component storage chamber.

[0027] The upper ends of the piston rods of the vertically arranged A-glue cylinder 31 and B-glue cylinder 32 are respectively equipped with A movable blocks 41 and B movable blocks 42 that can move vertically. The lower end of an A-glue push rod 51, which is coaxial with the A-glue storage cavity 21, is connected to the A movable block 41.

The front side plate 103 of the housing 1 is provided with A strip-shaped holes 71 and B strip-shaped holes 72 extending in the vertical direction. An A indicator block 81 located on the outside of the front side plate 103 of the housing 1 is connected to the end face of the A movable block 41 away from the piston rod of the A glue cylinder 31 by a pin 9 passing through the A strip-shaped hole 71.

Both the A indicator block 81 and the B indicator block 82 have an indicator part 10. An indicator barcode 11 that cooperates with the indicator part 10 is provided on the front surface of the front side plate 103 of the housing 1.

[0028] The front surface of the front panel of the housing is provided with an indicator barcode that works with the indicator unit. This barcode provides real-time feedback on changes in the liquid level in the glue tank during the two-component glue supply process. This allows for timely adjustment of the glue dispensing volume, avoids imbalance in the two-component glue ratio, and improves the quality of the final mixed glue.

[0029] A rotating rod 17 is provided between two support columns 16 located on both sides of the first feed notch 142. One end of the rotating rod 17 is rotatably mounted on one support column 16, and the other end of the rotating rod 17 is connected to a mounting block 19 fixedly mounted on the support column 16 by bolts 18. A groove 171 is provided on the rotating rod 17 for the other support column 16 to be inserted.

[0030] Two of the aforementioned indicator sections 10 are arranged facing each other on opposite sides of indicator block A 81 and indicator block B 82; the inner diameter of the aforementioned glue storage cavity 21 is larger than the inner diameter of the glue storage cavity 22.

[0031] The working principle of this utility model is as follows:

[0032] In use, first loosen the bolt on the rotating rod, then rotate one end away from the support column. Next, push the glue bucket into the contour hole on the carrier block through the first feed notch. Simultaneously, the protrusion on the glue bucket enters the guide hole through the second feed notch and slides from one end to the other, thus accurately installing the glue bucket. This ensures that the A-grade pusher plate and the B-grade pusher plate can be correspondingly embedded in the A-grade storage cavity and the B-grade pusher plate, respectively. The typical volumes of the A-grade and B-grade storage cavities are 490ml, 200ml, and 150ml, respectively.

[0033] In the initial state, the piston rods of both the A-type and B-type glue cylinders are in the retracted state. When glue supply begins, the piston rods of the A-type and B-type glue cylinders move upwards simultaneously, driving the A-type push rod and the B-type push rod to move upwards respectively. This further drives the A-type push plate and the B-type push plate to move upwards respectively, pushing the A-type glue and B-type glue liquid in the A-type glue storage chamber and the B-type glue storage chamber to be supplied outwards from their respective glue outlets at the top.

[0034] At the same time, indicator blocks A and B move upward along with the piston rods of the A and B glue cylinders, thereby visually displaying the changes in the liquid level of the glue in the A and B glue storage chambers through the cooperation of the two indicator parts located on the outside of the housing and the indicator barcode.

[0035] When the above-mentioned fluid level monitoring and supply device is used, it can provide real-time feedback on the changes in the liquid level in the glue bucket through the indicator barcode set on the front surface of the housing in conjunction with the indicator part during the two-component glue supply process. This is conducive to timely adjustment of the glue dispensing volume, avoiding the imbalance of the two-component glue ratio, and improving the quality of the final mixed glue. Furthermore, it can realize the quick loading and unloading of the glue bucket and ensure the relative positional accuracy between the glue bucket installation position and the A glue pusher plate and the B glue pusher plate, avoiding the situation where the glue bucket position is offset and glue cannot be pushed out.

[0036] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
