Description

Technical Field

[0001] This invention relates to the field of production equipment technology for hemodialysis tubing, and in particular to a packaging device for hemodialysis tubing. Background Technology

[0002] Currently, the packaging of hemodialysis tubing is usually done manually. Since the tubing is packaged between the mold cavity and the dialysis paper, and there is usually a large gap between the inner mold cavity and the dialysis paper, the fittings and tubing of the hemodialysis tubing in the mold cavity can easily pop out. This can lead to the risk of pressure or burns to the hemodialysis tubing during the heat sealing of the dialysis paper. In addition, this manual packaging is also prone to product stacking during transportation, which can cause the fittings of the hemodialysis tubing to fall off, deform, or bend. Summary of the Invention

[0003] The purpose of this invention is to provide a packaging device for hemodialysis tubing that not only avoids product stacking during transportation, but also prevents damage to the hemodialysis tubing during heat sealing.

[0004] To achieve the above objectives, the present invention provides a packaging device for hemodialysis tubing, comprising: a feeding mechanism, a first conveying mechanism, a mold cavity, a spot welding mechanism, a second conveying mechanism, and a hot-melt mechanism; the top surface of the mold cavity has a placement groove and is disposed in the first conveying mechanism; the feeding mechanism is disposed on one side of the first conveying mechanism and is used to place the hemodialysis tubing into the placement groove and to place dialysis paper on the top surface of the mold cavity and seal the placement groove; the spot welding mechanism is disposed at one end of the first conveying mechanism, and the first conveying mechanism is used to convey the mold cavity to the spot welding mechanism; the spot welding mechanism includes a driving assembly, a pressure plate, and a welding torch, the driving assembly and the pressure plate being connected... A connection is provided to drive the pressure plate to move toward the placement groove, so as to adhere and fix the dialysis paper to the top surface of the mold cavity and press and fix the blood dialysis tube to the placement groove. The pressure plate has multiple welding holes, which are spaced apart circumferentially along the mold cavity and penetrate the pressure plate. The welding gun passes through the welding holes and is used to spot weld and fix the dialysis paper to the top surface of the mold cavity. One end of the second transmission mechanism is connected to the spot welding mechanism and the other end is connected to the hot melt mechanism. The second transmission mechanism is used to transfer the mold cavity from the spot welding mechanism to the hot melt mechanism, and the hot melt mechanism is used to hot melt and press the dialysis paper to the top surface of the mold cavity.

[0005] Optionally, a pulling mechanism is also included. The feeding mechanism includes a receiving box and a moving component. The receiving box includes a frame and a base plate. The bottom of the frame has a groove. The base plate is slidably connected to the groove and together with the frame forms a receiving groove. The receiving groove is used to receive dialysis tubing. The moving component is used to move the receiving box above the placement groove. The pulling mechanism is located on one side of the first transmission mechanism and is used to pull the base plate out of the groove so that the dialysis tubing located in the receiving groove falls into the placement groove.

[0006] Optionally, the feeding mechanism further includes a paper feeding assembly, which is located on one side of the first transmission mechanism and is used to place the dialysis paper onto the top surface of the mold cavity.

[0007] Optionally, the mold cavity further includes a guide plate, which is disposed on the top surface of the mold cavity and has a guide groove on the top surface of the guide plate. The guide groove passes through the guide plate and communicates with the placement groove. The moving component is used to slide the receiving box along the guide groove to correspond to the placement groove.

[0008] Optionally, the moving component includes a guide rail and a clamping member. The guide rail is disposed on one side of the first transmission mechanism, and the clamping member is slidably connected to the guide rail and is used to clamp the receiving box. As the clamping member slides along the guide rail, the receiving box can move above the placement slot.

[0009] Optionally, a pressing and following mechanism is also included. The pressing and following mechanism is located on one side of the first transmission mechanism. The pressing and following mechanism includes a transmission component and a pressing component. The pressing component is located on the transmission component. The pressing component is used to press the blood dialysis tube in the receiving groove into the placement groove. The transmission component is used to drive the pressing component to move together with the blood dialysis tube to the spot welding mechanism.

[0010] Optionally, the clamping assembly includes a frame, a lifting motor, and a push plate. The frame is disposed on the conveying assembly, the lifting motor is disposed on the frame, and the push plate is connected to the output end of the lifting motor and is correspondingly disposed with respect to the receiving groove.

[0012] Compared with the prior art, the packaging device for hemodialysis tubing of this invention has the following advantages: By setting up a spot welding mechanism, the hemodialysis tubing is first fixed in the placement groove of the mold cavity by a pressure plate before being fixed by the dialysis paper and the mold cavity through heat fusion pressing, and then fixed by spot welding with a welding gun. This avoids the hemodialysis tubing being crushed or burned during the subsequent heat fusion pressing process. Moreover, since the welding gun passes through the welding hole on the pressure plate to spot weld the dialysis paper and the mold cavity, the setting of the welding hole can also determine the spot welding position and avoid damage to the hemodialysis tubing. In addition, by setting up a feeding mechanism, a first transmission mechanism and a second transmission mechanism, this invention can also realize the automated packaging of hemodialysis tubing, and can also avoid the product stacking during transportation, thereby avoiding the situation of accessories falling off, deforming, or kinking during transportation.

Detailed Implementation

[0017] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0018] In the description of this invention, it should be understood that the terms "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] like Figures 1-3 As shown, an embodiment of the present invention provides a packaging device for hemodialysis tubing, comprising: a feeding mechanism 1, a first transmission mechanism 2, a mold cavity 3, a spot welding mechanism 4, a second transmission mechanism 5, and a hot-melt mechanism 6; the top surface of the mold cavity 3 has a placement groove 31 and is disposed on the first transmission mechanism 2; the feeding mechanism 1 is disposed on one side of the first transmission mechanism 2, and is used to place the hemodialysis tubing into the placement groove 31, and to place dialysis paper on the top surface of the mold cavity 3 and seal it in the placement groove 31; the spot welding mechanism 4 is disposed at one end of the first transmission mechanism 2, and the first transmission mechanism 2 is used to transmit the mold cavity 3 to the spot welding mechanism 4; the spot welding mechanism 4 includes a driving assembly, a pressure plate 41, and a welding torch, the driving assembly being connected to the pressure plate 41 for driving... The pressure plate 41 moves toward the placement groove 31 to adhere and fix the dialysis paper to the top surface of the mold cavity 3 and to press and fix the blood dialysis tube to the placement groove 31. The pressure plate 41 has a plurality of welding holes 411, which are spaced apart circumferentially along the mold cavity 3 and penetrate through the pressure plate 41. The welding gun passes through the welding holes 411 and is used to spot weld and fix the dialysis paper to the top surface of the mold cavity 3. One end of the second transmission mechanism 5 is connected to the spot welding mechanism 4 and the other end is connected to the hot melt mechanism 6. The second transmission mechanism 5 is used to transfer the mold cavity 3 from the spot welding mechanism 4 to the hot melt mechanism 6. The hot melt mechanism 6 is used to hot melt and press the dialysis paper to the top surface of the mold cavity 3.

[0021] Based on the above solution, this application sets up a spot welding mechanism 4 so that the blood dialysis tube is first fixed in the placement groove 31 of the mold cavity 3 by the pressure plate 41 before being fixed by the dialysis paper and the mold cavity 3 through hot melting and pressing. Then, it is spot welded by the welding gun, thereby avoiding the blood dialysis tube being crushed or burned during the subsequent hot melting and pressing process. Moreover, since the welding gun passes through the welding hole 411 on the pressure plate 41 to spot weld the dialysis paper and the mold cavity 3, the setting of the welding hole 411 can also determine the spot welding position and avoid damage to the blood dialysis tube. In addition, this application can also realize the automated packaging of blood dialysis tubes by setting up the feeding mechanism 1, the first transmission mechanism 2 and the second transmission mechanism 5, and can also avoid the product stacking during transportation, thereby avoiding the situation of accessories falling off, deforming or bending the tube during transportation.

[0022] like Figure 1 and Figure 2 As shown, to facilitate the transfer of hemodialysis tubing, a pulling mechanism is also included. The feeding mechanism 1 includes a receiving box 11 and a moving component 12. The receiving box 11 includes a frame and a base plate. The bottom of the frame has a groove, and the base plate is slidably connected to the groove, forming a receiving groove together with the frame. The receiving groove is used to receive hemodialysis tubing. The moving component 12 is used to move the receiving box 11 above the placement groove 31. The pulling mechanism is located on one side of the first transfer mechanism 2 and is used to pull the base plate out of the groove so that the hemodialysis tubing in the receiving groove falls into the placement groove 31. By setting the receiving box 11 as a container for the hemodialysis tubing, damage to the hemodialysis tubing during the process from the feeding mechanism 1 to the mold cavity 3 is avoided. Furthermore, the separation of the hemodialysis tubing from the receiving box 11 by sliding the base plate can also avoid direct contact with the hemodialysis tubing, reducing the risk of contamination.

[0023] like Figure 1 and Figure 2 As shown, for ease of use, the feeding mechanism 1 also includes a paper feeding assembly 7, which is located on one side of the first transmission mechanism 2 and is used to place the dialysis paper onto the top surface of the mold cavity 3.

[0024] like Figure 1 and Figure 2 As shown, in order to ensure that the receiving box 11 can correspond to the mold cavity 3, the mold cavity 3 also includes a guide plate 32. The guide plate 32 is disposed on the top surface of the mold cavity 3, and the top surface of the guide plate 32 has a guide groove. The guide groove passes through the guide plate 32 and is connected to the placement groove 31. The moving component 12 is used to slide the receiving box 11 along the guide groove to correspond to the placement groove 31.

[0025] like Figure 1 and Figure 2 As shown, for ease of use, the moving component 12 includes a guide rail 121 and a clamping member 122. The guide rail 121 is located on one side of the first transmission mechanism 2. The clamping member 122 is slidably connected to the guide rail 121 and is used to clamp the receiving box 11. As the clamping member 122 slides along the guide rail 121, the receiving box 11 can move above the placement slot 31. Through the arrangement of the clamping member 122 and the guide rail 121, the receiving box 11 is suspended during transportation, allowing for direct observation of the blood dialysis tubing and facilitating visual inspection.

[0026] like Figure 1 and Figure 2As shown, for ease of use, a pressing and following mechanism 8 is also included. The pressing and following mechanism 8 is located on one side of the first transmission mechanism 2. The pressing and following mechanism 8 includes a transmission component and a pressing component 81. The pressing component 81 is located on the transmission component. The pressing component 81 is used to press the blood dialysis tube in the receiving groove into the placement groove 31. The transmission component is used to drive the pressing component 81 to move together with the blood dialysis tube to the spot welding mechanism 4. By setting the pressing and following mechanism 8, the blood dialysis tube is always in a pressed state during the process of being transported to the spot welding mechanism 4, thereby avoiding the situation where the accessories of the blood dialysis tube pop out.

[0027] like Figure 1 and Figure 2 As shown, for ease of use, the clamping assembly 81 includes a frame 811, a lifting motor, and a push plate 812. The frame 811 is disposed on the conveying assembly, the lifting motor is disposed on the frame 811, and the push plate 812 is connected to the output end of the lifting motor and is disposed corresponding to the receiving groove. The lifting motor is used to drive the push plate 812 to move toward the receiving groove.

[0028] like Figure 1 and Figure 2 Figure 1 Figure 2 As shown, in order to improve packaging efficiency, the system includes multiple mold cavities 3. The first transmission mechanism 2 includes a stepper motor and a transmission belt. The stepper motor is driven to the transmission belt, and the multiple mold cavities 3 are sequentially arranged on the transmission belt.

[0029] In summary, this invention provides a packaging device for hemodialysis tubing. By setting a spot welding mechanism 4, the hemodialysis tubing is first fixed in the placement groove 31 of the mold cavity 3 by the pressure plate 41 before being fixed by the dialysis paper and the mold cavity 3 through heat fusion pressing. Then, it is spot welded by a welding gun, thereby avoiding damage or burns to the hemodialysis tubing during the subsequent heat fusion pressing process. Moreover, since the welding gun passes through the welding hole 411 on the pressure plate 41 to spot weld the dialysis paper and the mold cavity 3, the setting of the welding hole 411 can also determine the spot welding position and avoid damage to the hemodialysis tubing. In addition, this application can also realize automated packaging of hemodialysis tubing by setting a feeding mechanism 1, a first transmission mechanism 2 and a second transmission mechanism 5, and can also avoid product stacking during transportation, thereby avoiding the situation of accessories falling off, deforming, or folding the tubing during transportation.

[0030] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
