Description

Technical Field

[0001] This utility model relates to the technical field of glue coating equipment, specifically to a novel two-component reciprocating metering cylinder. Background Technology

[0002] A glue applicator is a device used to evenly apply glue or other adhesive materials to the surface of an object. It is widely used in many industries such as packaging, electronics, automobiles, and furniture.

[0003] An AB glue applicator is a device specifically designed for the precise mixing and application of two-component adhesives, A and B. It is widely used in industrial production and certain handicrafts. The AB glue applicator stores A and B glue in two separate tanks. A high-precision metering pump extracts the two adhesives according to a set ratio, mixes them thoroughly in a mixing tube, and finally applies the mixed AB glue evenly to the surface of the objects to be bonded through a coating head.

[0004] A Chinese patent with publication number CN217411317U discloses a desktop A / B glue dispensing mechanism, belonging to the field of glue dispensing devices. It includes a housing, a first glue cylinder, a second glue cylinder, a gear pump, and a drive unit. The gear pump comprises a first gear pump and a second gear pump. The input end of the first gear pump is connected to the first glue cylinder, and the input end of the second gear pump is connected to the second glue cylinder. Both the first and second gear pumps are connected to the drive unit. The output ends of both the first and second gear pumps pass through the housing and are connected to the outside. The drive unit is configured in two sets, each set including a motor, a synchronous belt, and synchronous pulleys. The motor is fixed inside the housing. Each set of drive units has two synchronous pulleys, and the synchronous pulleys in the two sets of drive units are independent of each other and are respectively connected to the first and second gear pumps.

[0005] However, existing technologies lack pumps capable of continuously and uninterruptedly outputting AB glue. Therefore, a new type of two-component reciprocating metering cylinder is needed, which can not only continuously and uninterruptedly output glue, but also make the mixing ratio of A and B glue more accurate, and make the switching between the opening and closing of A and B inlets more sensitive and precise.

[0041] Import / export assembly cover plate 21 Detailed Implementation

[0042] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0043] like Figure 1-7As shown, a novel dual-component reciprocating metering cylinder according to this utility model includes: a first-stroke cylinder 1, a second-stroke cylinder 2, and an inlet / outlet assembly. The first-stroke cylinder 1 and the second-stroke cylinder 2 perform synchronous reciprocating motion in opposite directions. The output ends of the first-stroke cylinder 1 and the second-stroke cylinder 2 are connected to the internal channels of the inlet / outlet assembly. Each inlet / outlet assembly is correspondingly provided with an inlet / outlet switch control cylinder. The inlet switch control cylinder and the outlet switch control cylinder of the same stroke cylinder do not open or close simultaneously. The two inlet switch control cylinders do not open or close simultaneously, and the two outlet switch control cylinders do not open or close simultaneously. Both the first-stroke cylinder 1 and the second-stroke cylinder 2 include a component A cylinder body and a component B cylinder body. The component A cylinder body and the component B cylinder body perform synchronous reciprocating motion in the same direction. The volume ratio of the component A cylinder body and the component B cylinder body is consistent with the volume ratio of the glue mixture. The inlet / outlet assembly includes an inlet / outlet assembly cover plate 21, on which the component A inlet / outlet and the component B inlet / outlet are correspondingly provided.

[0044] This application employs a single-stroke synchronous control to ensure the movement of components A and B of the adhesive and that the volume ratio of A and B cavities matches the total volume ratio of the mixed adhesive, resulting in a more precise mixing ratio of A and B adhesives. The dual-stroke switching design ensures a continuous flow of adhesive. A single cylinder simultaneously controls the opening and closing of the A and B inlets and outlets, making the switching process more sensitive and precise.

[0045] A first-stroke cylinder sensor 3 is installed above the first-stroke cylinder 1, and a magnetic device is installed inside the piston of the first-stroke cylinder 1.

[0046] A second-stroke cylinder sensor 4 is installed above the second-stroke cylinder 2, and a magnetic device is installed inside the piston of the second-stroke cylinder 2.

[0047] When the first-stroke cylinder 1 is ventilated, the piston inside the cylinder moves to the left with a magnetic field inside, until the pneumatic magnetic switch of the first-stroke cylinder sensor 3 is triggered, controlling the air circuit to switch to ventilate the second-stroke cylinder 2. At the same time, the first-stroke A-component cylinder 12 and the first-stroke B-component cylinder 9 rapidly apply glue, causing the piston of the first-stroke cylinder 1 to move to the right until the end. The piston of the second-stroke cylinder 2, with a magnetic field inside, moves to the left. When the pneumatic magnetic switch of the second-stroke cylinder sensor 4 is triggered, the air circuit switches back to its original path, and the second-stroke A-component cylinder 16 and the second-stroke B-component cylinder 14 rapidly apply glue, causing the piston of the second-stroke cylinder 2 to move to the right until the end. This cycle continues.

[0048] The inlet / outlet assembly is equipped with a first-stroke outlet switch control cylinder 5 and a first-stroke inlet switch control cylinder 7, which correspond to the first-stroke cylinder 1. When the first-stroke cylinder 1 approaches the inlet / outlet assembly, the first-stroke outlet switch control cylinder 5 opens the outlet, and the first-stroke inlet switch control cylinder 7 closes the inlet.

[0049] The inlet / outlet assembly is equipped with a second stroke outlet switch control cylinder 6 and a second stroke inlet switch control cylinder 8 corresponding to the second stroke cylinder 2. When the second stroke cylinder 2 approaches the inlet / outlet assembly, the second stroke outlet switch control cylinder 6 opens the outlet and the second stroke inlet switch control cylinder 8 closes the inlet.

[0050] When the first-stroke cylinder 1 approaches the inlet / outlet assembly, the second-stroke outlet switch controls the cylinder 6 to close its corresponding outlet, and the second-stroke inlet switch controls the cylinder 8 to open its corresponding inlet.

[0051] The first-stroke cylinder 1 includes the following components that can be detachably installed: a first-stroke B-component cylinder body 9, a first-stroke B-component piston 10, a first-stroke A-component piston 11, and a first-stroke A-component cylinder body 12. The internal cavity of the first-stroke B-component cylinder body 9 is connected to the inlet and outlet of component B, and the internal cavity of the first-stroke A-component cylinder body 12 is connected to the inlet and outlet of component A.

[0052] The second-stroke cylinder 2 includes detachably mounted: a second-stroke B-component piston 13, a second-stroke B-component cylinder body 14, a second-stroke A-component piston 15, and a second-stroke A-component cylinder body 16. The internal cavity of the second-stroke B-component cylinder body 14 is connected to the inlet and outlet of component B, and the internal cavity of the second-stroke A-component cylinder body 16 is connected to the inlet and outlet of component A. In practical applications, when encountering situations with different adhesive ratios, components can be directly replaced according to the adhesive ratio.

[0053] The import / export assembly cover 21 is provided with a component A total outlet 17, a component A total inlet 18, a component B total outlet 19, and a component B total inlet 20, and a corresponding flow channel is provided on the import / export assembly cover 21.

[0054] This application utilizes the synchronous reciprocating left-right movements of the first-stroke cylinder 1 and the second-stroke cylinder 2 to simultaneously deliver the two-component adhesive. When the first-stroke cylinder 1 moves to the left, the first-stroke inlet switch control cylinder 7 is closed, and the first-stroke outlet switch control cylinder 5 is opened to deliver the adhesive to the first-stroke A-component cylinder 12 and the first-stroke B-component cylinder 9. Simultaneously, the second-stroke inlet switch control cylinder 8 is opened, and the second-stroke outlet switch control cylinder 6 is closed, allowing adhesive replenishment to begin in the second-stroke A-component cylinder 16 and the second-stroke B-component cylinder 14. The second-stroke cylinder 2 then moves to the right. When the first-stroke cylinder 1 triggers the signal from the first-stroke cylinder sensor 3, and the second-stroke cylinder 2 moves to the left, the second-stroke inlet switch control cylinder 8 is closed, and the second-stroke outlet switch control cylinder 6 is opened to deliver adhesive to the cavities of the second-stroke component A cylinder 16 and the second-stroke component B cylinder 14. Simultaneously, the first-stroke inlet switch control cylinder 7 is opened, and the first-stroke outlet switch control cylinder 5 is closed, allowing adhesive replenishment to begin in the first-stroke component A cylinder 12 and the first-stroke component B cylinder 9. The first-stroke cylinder 1 then moves to the right. The switching process repeats when the second-stroke cylinder 2 triggers the signal from the second-stroke cylinder sensor 4; this cycle continues, with adhesive continuously output from the outlet. The internal channel structure of the inlet / outlet assembly cover plate 21 is designed to merge the original multiple inlets / outlets into four.

[0055] This application adopts a standard cylinder design, which eliminates the need for power supply and enables full air-source control, resulting in a simpler structure, easier and more convenient maintenance, and lower costs.

[0056] This application adopts a design that controls the cyclical motion of the first-stroke cylinder 1 and the second-stroke cylinder 2, so that the glue is smoothly delivered in the first and second stroke cylinders, achieving a continuous and uninterrupted output effect.

[0057] This application uses a mechanism design that links the piston rod of the first stroke cylinder 1 to the piston rod of the first stroke A component 11 and the piston rod of the first stroke B component 10, so that the pistons of components A and B move synchronously, which solves the problem of asynchronous glue dispensing of components A and B and achieves the effect of accurate mixing ratio of components A and B glue.

[0058] This application solves the problem of inconsistent outlet switches for components A and B by using an inlet / outlet switch to control the cylinder rod of the cylinder, which links the switch rod and the ball to synchronously control the outlet switches of components A and B, thus achieving the effect of simultaneous glue dispensing.

[0059] This application, through the internal processing channel structure design of the import and export assembly cover plate 21, combines the import of component A in the first and second strokes, the export of component A in the first and second strokes, the import of component B in the first and second strokes, and the export of component B in the first and second strokes. This solves the problem of complex and cumbersome import and export links, while avoiding import and export interference, and makes the appearance simple and beautiful.
