Description

Technical Field

[0001] This utility model relates to the field of quantitative adhesive injection technology, and in particular to a quantitative adhesive injection device for pipeline bonding. Background Technology

[0002] Hemodialysis tubing is a key consumable in hemodialysis treatment, used to establish an extracorporeal blood circulation pathway, connect the patient to the dialysis machine, and allow blood to circulate safely and smoothly inside and outside the body to complete toxin removal and fluid balance regulation. The bonding quality of hemodialysis tubing directly affects the safety of dialysis treatment. The quantitative adhesive injection device ensures the sealing and reliability of tubing connections by precisely controlling the amount of adhesive. This device is suitable for bonding dialysis tubing materials such as polyvinyl chloride and silicone, meeting the requirements of medical-grade sterility and accurate measurement.

[0003] In pipeline bonding operations, precise quantitative dispensing of adhesive is a key step in ensuring bonding quality. Traditional pipeline bonding adhesive dispensing methods mostly rely on manual operation, such as manually squeezing the glue bottle or using a simple syringe to inject adhesive. This method not only makes it difficult to accurately control the amount of adhesive injected, which can easily lead to excessive glue and waste or insufficient glue and affect bonding strength, but also results in low efficiency and high labor intensity, which cannot meet the needs of large-scale pipeline bonding operations.

[0004] In view of the shortcomings of traditional glue injection methods and existing devices, this device solves the problems of inaccurate metering and inconvenient operation of traditional methods by filling glue from the storage bottle into the limiting sleeve, and then using the connection between the glue dispensing tube and the tube head to achieve precise extraction and injection of glue through pressing operation.

[0005] In view of the above-mentioned defects of traditional glue injection methods and existing devices, this device solves the problems of inaccurate quantitative measurement and inconvenient operation of traditional methods by filling glue from the storage bottle into the limiting sleeve, and then using the sleeve connection between the glue dispensing tube and the tube head to achieve precise extraction and injection of glue through pressing operation. This utility model is proposed.

[0006] Therefore, the purpose of this utility model is to solve the problem of inaccurate metering in traditional manual glue dispensing by designing a bottle and limiting sleeve. This ensures accurate glue volume, avoids waste and insufficient bonding strength, and simplifies the operation of the dispensing tube by pressing it.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0022] Reference Figure 1-4This is the first embodiment of the present invention, which provides a quantitative glue injection device for pipe bonding, including a quantitative glue injection base plate 1 and a glue injection fixing box 2 on one side of the quantitative glue injection base plate 1. The glue injection fixing box 2 is provided with a limiting sleeve 3 inside, and a limiting connecting block 4 is provided on one side of the limiting sleeve 3. It includes a fixed limiting plate 7 installed on one side of the limiting sleeve 3, a fixed sleeve 10 on one side of the fixed limiting plate 7, a constraint sleeve 12 on one side of the fixed sleeve 10, a fixed connecting block 5 on one side of the glue injection fixing box 2, a glue injection fixing groove 6 opened inside the fixed connecting block 5, and a supporting connecting plate 22 on one side of the quantitative glue injection base plate 1. A storage bottle 21 is provided on one side of the support connecting plate 22, and a glue dispensing head 20 is provided on one side of the storage bottle 21. One end of the glue dispensing head 20 is inserted into the inner side of the corresponding glue injection fixing groove 6. A glue dispensing hole 23 is opened on the limiting sleeve 3. The glue dispensing hole 23 is connected to the glue injection fixing groove 6. A limiting connecting groove 8 is opened on one side of the fixing limiting plate 7. Example 2

[0023] Reference Figure 2-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that it includes a sealing connecting block 15 installed inside the fixing sleeve 10, a fixing constraint block 14 on one side of the sealing connecting block 15, a glue outlet tube 13 on one side of the fixing constraint block 14, one end of the limiting connecting block 4 being inserted into the inner side of the limiting connecting groove 8, a guide sleeve 9 on one side of the fixing limiting plate 7, and a glue outlet tube 13 on the inner side of the guide sleeve 9. A fixed constraint groove 16 is provided on the inner side of the fixed constraint block 14. A sealing ball 17 is provided on the inner side of the fixed constraint groove 16. A constraint connecting block 11 is provided on the inner side of the fixed sleeve 10. A return spring 19 is provided between the constraint connecting block 11 and the sealing connecting block 15. A fixed ball 18 is provided between the constraint connecting block 11 and the constraint sleeve 12. One end of the constraint sleeve 12 is located inside the limiting sleeve 3.

[0024] In use, the quantitative dispensing base plate 1 serves as the basic support structure, the dispensing fixing box 2 is fixed on the quantitative dispensing base plate 1, the storage bottle 21 is fixed to one side of the quantitative dispensing base plate 1 through the support connecting plate 22, and its dispensing head 20 is inserted into the dispensing fixing groove 6 of the dispensing fixing box 2. At this time, the glue in the storage bottle 21 flows into the inner side of the limiting sleeve 3 through the dispensing fixing groove 6 and the dispensing outlet hole 23 on the limiting sleeve 3, completing the initial filling. The fixing limiting plate 7 is connected to the limiting sleeve 3 through the limiting connecting block 4 to ensure the stability of the fixing component. The constraint sleeve 12 is installed on one side of the fixing sleeve 10, and one end of the constraint sleeve 12 is submerged in the liquid glue.

[0025] The tube head to be bonded is fitted onto the outside of the dispensing tube 13. The sealing ball 17 on the inside of the fixed constraint block 14 contacts the inner wall of the tube head to form a preliminary seal, preventing glue leakage during glue injection. The return spring 19 between the constraint connecting block 11 and the sealing connecting block 15 is in its natural state. The sealing connecting block 15 is located in the initial position inside the fixed sleeve 10. At this time, the glue in the limiting sleeve 3 remains stationary under the action of gravity and air pressure.

[0026] Pressing down the dispensing tube 13 causes the fixed constraint block 14 and sealing connection block 15 to move downward along the fixed sleeve 10. When the sealing connection block 15 moves, the volume of the cavity formed by it and the inner side of the fixed sleeve 10 increases, and the internal air pressure rises. Under the action of air pressure, the fixed ball 18 seals the constraint sleeve 12, so that the glue can only enter the inner side of the tube head to be bonded from the side of the dispensing tube 13. Then the sealing connection block 15 is reset by the return spring 19. Due to the increase in internal space, the internal pressure of the fixed sleeve 10 decreases, so the glue enters the inner side of the fixed sleeve 10 from the side of the constraint sleeve 12 under the action of air pressure. Thus, the tube head is removed, and the tube head containing glue is connected to the hose to complete the bonding, preparing for the next glue injection operation.

[0027] The remaining structure is the same as that in Example 1.

[0028] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
