[0028] The utility model discloses a device for coating the inner diameter of a dialyzer joint, such as Figure 1 As shown, it at least comprises: a frame telescopic device 3 at a fixed end, a glue coating rotating device 1 installed on the frame telescopic device 3, and a glue supply device 2 for providing glue liquid to the glue coating rotating device 1. The glue supply device 2 is located at the side of the glue coating rotating device 1, and the glue liquid in the glue supply device 2 enters the glue coating rotating device 1; the frame telescopic device 3 has a fixed frame 31.

[0029] When the dialysis tubing connector that needs to be coated with glue is in place, the frame telescopic device 3 extends the glue coating rotating device 1 to allow the porous glue outlet head 111 to enter the interior of the dialysis tubing connector; then the glue supply device 2 pressurizes the glue to squeeze out the glue, and then the glue coating rotating mechanism 1 drives the glue coating head to rotate to evenly apply the glue to the inner wall of the dialysis tubing connector.

[0030] like Figure 2As shown, the glue supply device 2 at least includes: a glue storage tank 21, a pressure pump 22 connected to the glue storage tank 21, an overflow valve 23 connected to the glue storage tank 21 and the pressure pump 22, an electromagnetic on-off valve 24, a waste liquid tank 25, a manual waste liquid valve 26 connected to the electromagnetic on-off valve 24, a liquid separation block 27 connected to the manual waste liquid valve 26, and a glue supply bracket 201. The glue storage tank 21, the pressure pump 22, the overflow valve 23, the electromagnetic on-off valve 24, and the waste liquid tank 25 are fixed on the glue supply bracket 201 in sequence.

[0031] The glue liquid generates a certain pressure through the pressure pump 22. When the electromagnetic on-off valve 24 is opened, the glue liquid in the glue storage tank 21 enters the liquid separation block 27 through the overflow valve 23, and then enters the glue coating rotating device 1 through the liquid separation. When the electromagnetic on-off valve 24 is closed, the glue liquid returns to the glue storage tank 21 through the overflow valve 23. The overflow valve 23 can control the flow of the glue liquid, greatly reducing the deviation of the glue coating amount.

[0032] The liquid separation block 27 is provided with a plurality of liquid separation holes (not shown), and the glue liquid of the glue supply device 2 enters into the glue coating rotating device 1 through the liquid separation holes of the liquid separation block 27 .

[0033] like Figure 3 and Figure 4 The glue coating rotating device 1 at least includes: a plurality of glue coating head mechanisms 11 arranged in parallel and connected to the liquid separation holes of the liquid separation block 27 of the corresponding glue supply device 2, a rotating seat 12 for fixing the plurality of glue coating head mechanisms 11, a slide rail driving device fixed on the rotating seat 12, and a gear device connected to the slide rail driving device and the plurality of glue coating head mechanisms 111.

[0034] The slide rail driving device includes a guide rail 13 sliding on a rotating seat 12 , a floating joint 14 , a rotary driving cylinder 15 connected to the floating joint 14 and fixed on the rotating seat 12 , and a driving block 17 fixed on the guide rail 13 and connected to the floating joint 14 .

[0035] The gear device includes a plurality of driven gears 16 meshed in sequence and fixed on the corresponding glue coating head mechanism 11 , a driving gear 19 driving the driven gears 16 to move, and a rack 18 meshed with the driving gear 19 and fixedly connected to the driving block 17 .

[0036] When the rotary drive cylinder 15 is extended and retracted, the drive block 17 and the rack 18 are driven to make linear motion, and the gluing head mechanism 11 is driven to rotate through the driving gear 19 and the driven gear 16, so that the linear motion is converted into rotation, driving the gluing head mechanism 11 to rotate.

[0037] like Figure 4The glue coating head mechanism 11 at least includes: a rotary connector 116 connected to the rotary seat 12, a gear 115, a bearing seat 114, a hollow shaft 113, a shaft cap 112, and a porous glue dispensing head 111. The porous glue dispensing head 111 is connected to the corresponding liquid dispensing hole of the liquid dispensing block 27; the rotary connector 116, the gear 115, the bearing seat 114 and the shaft cap 112 are arranged in sequence; one end of the hollow shaft 113 is connected to the rotary connector 116, and the other end is connected to the porous glue dispensing head 111; the gear 115 and the bearing seat 114 are sleeved on the hollow shaft 113;

[0038] The distributed glue can enter the porous glue head 111. When the electromagnetic on-off valve 24 is closed, the pressure is balanced, and the glue stays in the porous glue head 111 without being squeezed out. When the electromagnetic on-off valve 24 is opened, the pressure squeezes out the glue. Due to the small diameter of the porous holes, the amount of glue applied can be controlled by pressure, so that the glue is applied evenly without splashing.

[0039] When the joint to be glued is in place, the telescopic cylinder 32 is extended to move the glue coating rotating device 1 toward the dialyzer joint. When the porous glue outlet head 111 of the glue coating rotating device 1 enters the inner diameter of the dialyzer joint, the electromagnetic on-off valve 24 is energized, and the glue passes through the liquid separator block 27 into the corresponding glue coating rotating device 1. The middle cavity of the glue coating rotating device 1 can deliver the pressurized glue into the porous glue outlet head 111. Under the action of pressure, the glue is squeezed into the inner surface of the joint through the small holes, and then the rotation drive cylinder 15 is extended and retracted to drive the glue coating rotating device 1 to rotate and evenly apply the glue.

[0040] Under the guidance of the guide rail 13, the rotating drive cylinder 15 drives the rack 18 to make linear motion, and the rack 18 engages with the driving gear 19 to convert the linear motion into rotation. The rotating driving gear 19 drives the multiple driven gears 16 to rotate. Among them, the hollow shaft 113, the rotating connector 116, the gear 115, the shaft cover 112 and the porous glue head are all installed on the bearing seat 114 and can rotate. After rotation, the extruded glue is evenly applied to the inner wall of the joint.

[0041] In this embodiment, the liquid separation block 27 has 6 liquid separation holes, and the glue coating head mechanism 11 also has 6 pieces, so that the inner diameter glue coating device of the dialyzer connector can coat the inner walls of 6 connectors with glue at the same time.

[0042] The inner diameter glue coating device of the dialyzer joint of the utility model solves the problems of uneven inner diameter glue coating and splash prevention and has good reliability.

[0043] Therefore, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention.
