Description

Technical Field

[0001] This invention relates to the technical field of adhesive coating for infusion tubes, and in particular to a manual adhesive coating mechanism for the outer side of an infusion tube. Background Technology

[0002] With the widespread use of infusion, the safety and stability of infusion tubing end connections have received increasing attention in the industry. Tubing end bonding is a common connection method. Due to the different applications of infusion tubing, the types of adhesives used at the tubing ends and the bonding distances vary.

[0003] Extensive research revealed that existing technology publication number CN204052041U discloses a catheter external adhesive application device, comprising an adhesive collection box and an application head. The application head is installed on the upper edge of the adhesive collection box. Its key feature is that a peristaltic tube is inserted into the bottom of the adhesive collection box, with a peristaltic pump located in the middle of the tube. The other end of the peristaltic tube is connected to a conversion connector, the other end of which is inserted into the application head. The application head consists of an application block and a guide block. The outer contour of the application block is formed by connecting a large cylinder, a connecting column, and a small cylinder. The inner surface of the application block has a large cavity and a small cavity. The outer contour of the guide block is composed of a cylinder and a step. The inner surface of the guide block has a fixing cavity, a limiting cavity, and a guide opening. The upper cylindrical surface of the cylinder has an adhesive inlet hole. The outer surface of the connecting column of the application block is interference-fitted to the inner surface of the cylinder of the guide block. A drainage channel is formed between the small cylinder and the fixing cavity. This device features uniform adhesive application, fixed adhesive amount, fixed application length, and safe operation.

[0004] Existing adhesive application devices cannot effectively ensure that the adhesive enters the inside of the conduit, and the removal of the product after application is not very convenient.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a manual infusion tube external adhesive dipping mechanism, which would make it more industrially valuable. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the purpose of this invention is to provide a manual glue-dipped mechanism for the outside of the infusion tube.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] The manual infusion tube external glue-applying mechanism includes a support plate, a glue box, a cylinder connector, and a glue-applying mold. The support plate has a waste glue tank and a stepped groove arranged sequentially along the positive X-axis. The glue box is embedded in the stepped groove. A glue box cover is located on the top outer side of the glue box, covering it and securing it to the stepped groove with screws. On the side of the glue box near the waste glue tank, a sensor hole and a connector hole are arranged sequentially along the positive Y-axis. The cylinder connector is installed in the connector hole along the Z-axis, and a proximity sensor is installed in the sensor hole along the Z-axis. The glue-applying mold is installed in the glue box along the Y-axis on the side near the waste glue tank. Furthermore, a gap is provided between the bottom of the glue-dipping mold and the inner bottom of the glue box. A glue-dipping hole is provided in the middle of the glue-dipping mold, and a core needle hole is provided at the bottom of the inner side of the glue-dipping hole. A sensor plate hole is provided on the glue-dipping mold on the side of the glue-dipping hole along the negative Y-axis. The sensor plate is installed in the sensor plate hole. The fixed core needle passes through the glue-dipping hole along the Z-axis and is inserted into the core needle hole. The movable core needle is fitted inside the fixed core needle along the Z-axis. One end of the connector head is connected to the movable core needle, and one end of the connector head is connected to the drive end of the top of the pen-shaped cylinder provided in the cylinder connector. A threaded two-way valve is provided on one side of the cylinder connector.

[0009] As a further improvement of the present invention, a first indicator light hole and a second indicator light hole are provided on the support plate near the waste glue tank, and a button hole is provided on the support plate near the stepped groove. A first indicator light is provided in the first indicator light hole, a second indicator light is provided in the second indicator light hole, and a button is provided in the button hole.

[0010] As a further improvement of the present invention, a controller box is also provided at the bottom of the support plate below the waste glue tank, a controller is provided inside the controller box, and a box bottom plate is provided at the bottom of the controller box.

Two screws are passed through the springs to constrain the glue-dipping mold in the glue box.

[0013] By means of the above-described solution, the present invention has at least the following advantages:

[0014] This invention, through the structural design of a fixed core pin, a movable core pin, and an adhesive-coating mold, ensures that the inside of the product is not coated with adhesive while also facilitating product removal. During product removal, a pen-shaped cylinder pushes the movable core pin upward and continuously provides compressed air from the threaded two-way valve through the cylinder connector and the fixed core pin into the product, preventing product blockage and foreign objects from entering the product.

[0050] Brief description of the working process of this invention:

[0051] This mechanism involves manually inserting the infusion tube and controlling the operation time via controller 16. The operator picks up the product for the glue application process on the outside of the infusion tube, inserts one end of the product through the glue application hole 701 on the glue box cover 5, and the inside of the product fits onto the fixing pin 14. The product is then pushed downwards until its end face contacts the bottom surface of the glue application mold 7. This continues until the glue application mold 7 contacts the bottom of the glue box 4. During this process, the sensor plate 17 embedded on one side of the glue application mold 7 moves downwards along with the mold. When the glue application mold 7 contacts the bottom of the glue box 4, the proximity sensor 20 is triggered, and the control program starts timing. A range of values ​​is controlled to determine the glue application time. This time can be set according to the needs of different products and the type of glue. If the operator's glue application time is too long or too short, the red light (first indicator light 2) will be triggered, indicating that the bonding of the product will be judged as NG (Not Good). If the glue application time is within the range, the green light (second indicator light 3) will be triggered, indicating that the product bonding is OK. The control principle of controller 16 and the above control process are conventional technologies disclosed in the field. Therefore, they will not be elaborated here. Moreover, the above process is only an implementation process description of this organization. This organization is not limited to the above control process.

[0052] When the product is pulled out, the pen-shaped cylinder 13 pushes the internal movable core needle upward once (the number of times can be set according to actual needs), and continuously provides compressed air from the threaded two-way valve 18 through the cylinder connector 6 and the fixed core needle 14 into the product to prevent product blockage and foreign objects. Adhesive is injected into the adhesive box 4 through the upper and lower injection holes 404 and 405, and then overflows through the liquid level adjustment hole 401, forming a cycle. The liquid level in the adhesive box 4 can be adjusted by the liquid level adjustment screw 9 to ensure the adhesive level of the product. The design of the moving and stationary core needles ensures that the inside of the product is not coated with adhesive and facilitates product removal.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0054] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.
