Description

Technical Field

[0001] The invention relates to the technical field of blood circuit tube gluing, and in particular to a gluing jig. Background Art

[0002] Blood tubes are commonly used in hemodialysis, hemofiltration and hemodiafiltration treatment. When producing blood tubes, one end of the tube needs to be coated with glue so that a connector can be installed on the coated end. When coating, only the outer wall of the blood tube needs to be coated with glue, and no glue should enter the blood tube to ensure the production quality of the blood tube.

[0003] At present, the blood tube is generally coated with glue by hand. The specific method of manual coating is as follows: a culture dish is filled with glue, and a sponge is placed in it as a medium for conducting the glue. The operator places the outer wall of the blood tube horizontally on the sponge containing glue, applies force so that the blood tube is partially embedded in the sponge, and rotates the blood tube for one circle, so that the glue is evenly coated on the outer wall of the blood tube.

[0004] However, this method has certain operational difficulties, slow gluing speed, and is easily affected by the operation process, making it difficult to ensure the gluing quality. Summary of the invention

[0005] The purpose of the present invention is to provide a glue coating jig capable of efficiently coating blood tubes with glue.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a glue coating jig, comprising a box body with a first chamber, a horizontally arranged transmission shaft disposed in the first chamber, a driving mechanism for driving the transmission shaft to rotate, and a turntable disposed in the first chamber, the turntable having a first end face and a second end face; the first end face is opposite to the end face of the transmission shaft, and the transmission shaft is fixedly connected to the first end face of the turntable through a top core; a first glue coating hole is provided on the second end face; a second glue coating hole connected to the first chamber is provided on the surface of the box body, and the second glue coating hole is concentrically arranged with the first glue coating hole; a glue coating pipeline is provided in the turntable, and the glue coating pipeline has opposite inlet and outlet ends, the inlet end of the glue coating pipeline is provided on the side of the turntable and connected to the first chamber, and the outlet end of the glue coating pipeline is connected to the first glue coating hole.

[0007] Furthermore, a plurality of the glue coating pipelines are arranged at intervals along the rotating disk in an annular direction.

[0008] Furthermore, the box body is also provided with a glue supply tank and a connecting pipe, the glue supply tank is provided with a glue cavity for filling glue; the first chamber is connected with the inside of the glue supply tank through the connecting pipe; the connecting pipe is provided with a first opening and closing member.

[0009] Furthermore, a drainage hole connected to the glue supply tank is opened on the surface of the box body, and a second opening and closing member is arranged in the drainage hole.

[0010] Furthermore, it also includes a first stud, a first accommodating hole provided on the end surface of the transmission shaft, and a first through hole provided on the side surface of the transmission shaft and connected to the first accommodating hole; the top core has a first part inserted into the first accommodating hole, the first stud passes through the first through hole and is connected to the first part, and the first stud is also fixedly connected to the transmission shaft.

[0011] Furthermore, it also includes a second stud, a second accommodating hole provided on the first end face, and a second through hole provided on the side of the disc and connected to the second accommodating hole; the top core has a second part inserted into the second accommodating hole, the second stud passes through the second through hole and is connected to the second part, and the second stud is also fixedly connected to the disc.

[0012] Furthermore, the second accommodating hole is communicated with the first glue coating hole.

[0013] Furthermore, the second through hole is an oblong hole, and the length direction of the oblong hole is parallel to the axis of the rotating disk.

[0014] Furthermore, the driving mechanism is a motor.

[0015] Furthermore, the first chamber has a first opening opened on the surface of the box body, and a transparent cover is provided at the first opening.

[0016] Compared with the prior art, the glue coating jig according to the embodiment of the present invention has the following beneficial effects:

[0017] When the present invention is used to apply glue to the outer wall of the blood tube, the gluing can be done automatically without too much operation, the operation difficulty is low and the gluing quality can be guaranteed. Specifically, the first chamber is filled with glue that can partially immerse the turntable; the blood tube to be coated with glue is inserted into the first glue coating hole through the second glue coating hole; then, the turntable is driven to rotate, and the inlet end of the glue coating pipeline enters the glue as the turntable rotates. At this time, the glue coating pipeline and the first chamber are connected through the inlet end of the glue coating pipeline, and a communicating vessel is formed. Under the action of the glue pressure, part of the glue is driven by the pressure from the inlet end to the inside of the glue coating pipeline; the turntable continues to rotate, and the inlet end of the glue coating pipeline is separated from the glue and rotates to the upper part of the turntable. Under the action of gravity, the glue inside the glue coating pipeline enters the first glue coating hole through the outlet end of the glue coating pipeline, drips on the outer wall of the blood tube, and flows to both sides along the outer wall of the blood tube, so as to fully coat the outer wall of the blood tube in the first glue coating hole. When the inlet end of the glue coating pipeline is in the glue, in order to further improve the glue coating effect, the rotation speed of the turntable is controlled so that the inlet end of the glue coating pipeline is immersed in the glue for a long enough time so that enough glue enters the glue coating pipeline.

When applying glue, the blood tube is inserted from the second glue-applying hole 12 into the first glue-applying hole 31 , and glue is injected into the first chamber 11 , so that the turntable 3 is partially immersed in the glue.

[0030] Preferably, in one implementation, the driving mechanism is a motor.

[0031] Preferably, in one embodiment, see Figure 1 and Figure 2 , the box body 1 is installed on the fixing seat 5.

[0032] Preferably, in one embodiment, see Figure 1 and Figure 2 The glue coating pipeline 32 is arranged along the radial direction of the turntable 3 so that the glue can smoothly enter the first glue coating hole 31 from the glue coating pipeline 32 .

[0033] Specifically, in one implementation, see Figure 2 and Figure 4 The glue coating pipelines 32 are arranged at intervals along the rotating disk 3. When the rotating disk 3 rotates, the glue coating pipelines 32 simultaneously transport glue to the first glue coating hole 31, with high transport efficiency, and ensure that the amount of glue entering the first glue coating hole 31 is sufficient to coat the blood tube.

[0034] Specifically, in one implementation, see Figure 1 -3 and Figure 5 The box body 1 also has a glue supply tank 17 and a connecting pipe 14. The glue supply tank 17 has a glue cavity 172 for filling glue. The first chamber 11 is connected to the glue supply tank 17 through the connecting pipe 14. The connecting pipe 14 has a first opening and closing member 171. Before use, the glue cavity 172 is filled with glue.

[0035] Preferably, in one embodiment, see Figure 1 -3 and Figure 5 , the first opening and closing member 171 is a cover provided at one end of the communication pipe 14 and covering the third opening of the glue box 17. When in use, the cover is opened, the first chamber 11 and the glue supply tank 17 form a communicating vessel through the communication pipe 14, and the glue in the glue supply tank 17 flows into the first chamber 11 and fills the first chamber 11. At this time, the pressure on the surface of the glue in the first chamber 11 is equal to the pressure on the surface of the glue in the glue box 17.

[0036] Specifically, in one implementation, see Figure 1 -3. A groove 13 for accommodating the glue supply tank 17 is provided on the surface of the box body 1. The box body 1 is also provided with a drainage hole 15 connected to the groove 13. A second opening and closing member 16 is provided in the drainage hole 15.

[0037] Preferably, in one embodiment, the second opening and closing member 16 is a sealing cover.

[0038] Specifically, in one implementation, see Figure 1 -2, also includes a first stud, a first accommodating hole 21 provided on the end face of the transmission shaft 2, and a first through hole provided on the side of the transmission shaft 2 and connected to the first accommodating hole 21; the top core 4 has a first part inserted into the first accommodating hole 21, the first stud passes through the first through hole and is connected to the first part, and the first stud is also fixedly connected to the transmission shaft 2.

[0039] Specifically, in one implementation, see Figure 1 -2, also includes a second stud, a second accommodating hole 33 provided on the first end face, and a second through hole 35 provided on the side of the disk 3 and connected to the second accommodating hole 33; the top core 4 has a second part inserted into the second accommodating hole 33, the second stud passes through the second through hole 35 and is connected to the second part, and the second stud is also fixedly connected to the disk 3.

[0040] Specifically, in one implementation, see Figure 4 The second accommodating hole 33 is connected to the first glue coating hole 31 , and the aperture of the second accommodating hole 33 is larger than the aperture of the first glue coating hole 31 , and the top core 4 can abut on the end surface between the second accommodating hole 33 and the first glue coating hole 31 .

[0041] Specifically, in one implementation, see Figure 4The second through hole 35 is an oblong hole, and the length direction of the oblong hole is parallel to the axis of the rotating disk 3. After the blood tube is inserted into the first glue coating hole 31, it extends into the second accommodating hole 33 and abuts against the top core 4. The arrangement of the oblong hole can adjust the relative position of the rotating disk 3 and the top core 4 when they are fixedly connected, and then adjust the distance between the end surface of the rotating disk 3 and the top core 4, thereby adjusting the length of the blood tube entering the disk 3, and then adjusting the glue coating length of the blood tube.

[0042] Specifically, in one implementation, see Figure 1 -3, the first chamber 11 has a first opening 18, the first opening 18 is opened on the surface of the box body 1, and the first opening 18 and the second glue-spreading hole 12 are arranged on different surfaces, and a cover plate is arranged at the first opening 18. The cover plate is transparent, so as to facilitate observation of the glue condition in the first chamber 11.

[0043] Preferably, in one embodiment, see Figure 4 A notch 34 connected to the second accommodating hole 33 is also provided on the side of the turntable 3. When the turntable 3 is disassembled, the notch 34 is lifted by hand after the second stud is loosened to remove the turntable 3 from the top core 4.

[0044] The working process of the present invention is as follows: before applying glue, the cover of the glue box 17 is opened, the first chamber 11 and the glue supply tank 17 form a communicating vessel through the connecting pipe 14, the glue flows from the glue box 17 to the first chamber 11, and forms a predetermined height in the first chamber 11, and the predetermined height needs to be immersed in the part of the turntable 3. The driving mechanism is started, the driving mechanism drives the transmission shaft 2 to rotate, and the transmission shaft 2 drives the turntable 3 to rotate through the top core 4. When the turntable 3 rotates, the inlet end of the glue coating pipeline 32 enters the glue as the turntable 3 rotates. At this time, the glue coating pipeline 32 and the first chamber 11 are connected through the inlet end of the glue coating pipeline 32 to form a communicating vessel. Under the action of the glue pressure, part of the glue is driven by the pressure from the inlet end to enter the inside of the glue coating pipeline 32; the turntable 3 continues to rotate, and the inlet end of the glue coating pipeline 32 is separated from the glue and rotates to a position where the height of the outlet end is lower than the height of the inlet end. Under the action of gravity, the glue in the glue coating pipeline 32 enters the first glue coating hole 31 through the outlet end of the glue coating pipeline, drips on the outer wall of the blood tube, and flows to both sides along the outer wall of the blood tube to fully coat the outer wall of the blood tube in the first glue coating hole 31. When the inlet end of the glue coating pipeline 32 is in the glue, in order to further improve the glue coating effect, the rotation speed of the turntable 3 is controlled so that the inlet end of the glue coating pipeline 32 is immersed in the glue for a long enough time, so that enough glue enters the glue coating pipeline 32. The turntable 3 continues to rotate, and the glue coating pipeline 32 gradually becomes vertical. Under the action of gravity, the glue in the glue coating pipeline 32 moves to the outlet end of the glue coating pipeline 32, enters the first glue coating hole 31 and smears the blood tube in the first glue coating hole 31. At the same time, during the rotation process, the glue in the first glue coating hole 31 can flow into the second receiving hole 33 connected to the first glue coating hole 31, and return to the first chamber 11 through the oblong hole or notch 34 in the second receiving hole 33.

[0045] In summary, the embodiment of the present invention provides a glue coating jig, which drives the glue filled in the first chamber 11 to enter the first glue coating hole 31 from the first chamber 11 when the turntable 3 rotates, and coats the outer wall of the blood tube inserted into the first glue coating hole 31. During the glue coating process, the user only needs to insert the blood tube into the first glue coating hole 31, and the glue coating is automatically performed without excessive operations. The operation difficulty is low and the glue coating quality can be guaranteed.

[0046] Furthermore, the glue of the gluing jig of the present invention is placed in the first chamber 11 and the glue supply tank 17, the first opening 18 of the first chamber 11 is covered with a cover plate, and the glue supply tank 17 is connected to the first chamber 11 through a connecting pipe 14. The glue will not be directly exposed to the workshop environment. Compared with the existing method of manually applying glue in which the glue is directly exposed to the workshop environment, the present invention will not affect the workshop environment.
