Description

Technical Field

[0001] This invention relates to the technical field of infusion set feeding equipment, specifically to a method for straightening an infusion set. Background Technology

[0002] Disposable infusion sets are commonly used medical consumables. There are many types of infusion sets, typically consisting of an intravenous infusion needle, needle hub, long tubing, flow regulator, drip chamber, short tubing, and medication syringe. However, in ordinary infusion sets, when the medication initially enters the drip chamber, a mixture of gas and medication easily forms. This gas-liquid mixture quickly enters the infusion tubing below the drip chamber, forming air bubbles during infusion and posing a threat to the patient's health. Therefore, automatic air-venting infusion sets have been developed. These sets have an air vent pipe installed at the bottom of the drip chamber, with a semi-closed top. The air vent pipe connects to the medication syringe and short tubing. This structure avoids the problem of air bubbles generated by liquid impact during venting and air bubbles trapped inside the tubing, truly achieving automatic venting without the need for manual inversion of the drip chamber or manual intervention. To ensure the hygiene and safety of medical infusion sets, they must be individually packaged and sterilized after assembly and production. Therefore, the requirements for the automation level of infusion set packaging are increasing. Medical infusion sets are flexible and linear objects, requiring material handling, winding, and post-winding conveying processes before packaging. A search revealed that Chinese patent CN212048048U discloses an automatic feeding device for infusion sets, including a frame, a slide rail, a tail feeding mechanism, and a head feeding mechanism. The slide rail is fixedly installed on the top of the frame along the X-axis, and the tail feeding mechanism and the head feeding mechanism are slidably installed on the slide rail. The tail feeding mechanism includes a first feeding mounting profile, a profile longitudinal moving component and a profile translation component disposed at the upper end of the first feeding mounting profile, and multiple sets of tail feeding components spaced apart at the lower end of the first feeding mounting profile. The head feeding mechanism includes a second feeding mounting profile, a profile longitudinal moving component and a profile translation component disposed at the upper end of the second feeding mounting profile, and multiple sets of head feeding components spaced apart at the lower end of the second feeding mounting profile. The shortcomings of the above patent are: First, the aforementioned patent straightens the infusion set through a tail-end material-collecting mechanism and a head-end material-collecting mechanism. However, this patent can only straighten the long tubing of the infusion set. Existing infusion sets contain not only long tubing but also short tubing, and the aforementioned patent cannot straighten the short tubing, thus failing to straighten the entire infusion set. Second, for infusion sets containing an exhaust pipe, there are short tubing, an exhaust pipe, and a medicine needle at the end of the drip chamber away from the long tubing. With many components, the short tubing and exhaust pipe of multiple infusion sets become entangled, which is not only inconvenient for material collection but also unfavorable for winding operations. Third, the short tubing of existing infusion sets is inclined relative to the long tubing, such as in Y-type three-way infusion sets. The aforementioned patent cannot straighten the inclined short tubing. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a method for straightening an infusion set that has an ingenious structure, allows the infusion set to be straightened as a whole, has high feeding efficiency, allows the direction of the exhaust pipe to be adjusted, allows the inclined short tubing to be straightened, and facilitates subsequent winding operations.

Step 2: Drive the grippers of the fourth straightening mechanism to grab the flow regulator or dripping bucket; Step 3: Drive the jaws of the second straightening mechanism to open, drive the first straightening mechanism to move away from the second straightening mechanism, and the first straightening mechanism will drive the drip chamber of the infusion set to pass through the jaws of the fourth straightening mechanism. At this time, the jaws of the fourth straightening mechanism will grab the end of the drip chamber away from the flow regulator. Alternatively, the fourth straightening mechanism can be driven to move away from the straightening mechanism of the long tubing of the infusion set. The grippers of the fourth straightening mechanism pass through the drip chamber and stop when the grippers of the fourth straightening mechanism grab the end of the drip chamber away from the flow regulator. Alternatively, the first straightening mechanism and the second straightening mechanism can be driven to move away from the fourth straightening mechanism at the same time. The first straightening mechanism and the second straightening mechanism can drive the drip chamber of the infusion set to pass through the gripper of the fourth straightening mechanism.

Alternatively, the first and second straightening mechanisms can be driven to move away from the fourth straightening mechanism, causing the entire infusion set to move until the gripper of the fourth straightening mechanism abuts against the end of the short tubing connected to the exhaust pipe.

[0011] The infusion set straightening method of the present invention further includes step five: driving the gripper of the third straightening mechanism to grasp the end of the drip chamber away from the flow regulator, so as to facilitate the gripper of the short tubing supporting the infusion set by the gripper of the third straightening mechanism.

[0012] The infusion set straightening method of the present invention further includes orderly operation of the vent pipe: driving the first straightening mechanism to move towards the fourth straightening mechanism, or driving the fourth straightening mechanism to move towards the first straightening mechanism, or driving the first straightening mechanism and the fourth straightening mechanism to move towards each other, so that the infusion set is in a relaxed state and the vent pipe hangs down under its own gravity; driving the first straightening mechanism and / or the fourth straightening mechanism to return to their original positions to ensure that the vent pipe remains hanging down when the infusion set is in a straightened state.

When the flow regulator 6 of the infusion set 3 moves away from the needle seat 5, the grippers of the first straightening mechanism 1 and the second straightening mechanism 2 grip the long tubing 4 between the needle seat 5 and the flow regulator 6. After the first straightening mechanism 1 and the second straightening mechanism 2 move away from each other, the outer end of the gripper of the first straightening mechanism 1 abuts against the needle seat 5 at one end of the long tubing 4, and the outer end of the gripper of the second straightening mechanism 2 abuts against the flow regulator 6 at the other end of the long tubing 4, thus straightening the long tubing 4 of the infusion set 3. When the flow regulator 6 of the infusion set 3 approaches the needle seat 5, the grippers of the first straightening mechanism 1 and the second straightening mechanism 2 grasp the long tubing 4 between the flow regulator 6 and the drip chamber 8 of the infusion set 3.

The gripper of the third straightening mechanism 7 passes through the dripping bucket 8 and stops when the gripper of the third straightening mechanism 7 grabs the end of the dripping bucket 8 away from the flow regulator 6. Alternatively, the first straightening mechanism 1 and the second straightening mechanism 2 can be driven to move away from the third straightening mechanism 7 at the same time. The first straightening mechanism 1 and the second straightening mechanism 2 can drive the dripping bucket 8 of the infusion set 3 to pass through the gripper of the third straightening mechanism 7.

The third straightening mechanism 7 includes a third gripper 17, a third gripper drive cylinder 18, and a third gripper drive moving assembly. The third gripper 17 is provided on one side of the long catheter straightening mechanism 15 of the infusion set.

According to the position of the exhaust pipe, the lever 33 is driven to rotate horizontally by the horizontal lever motor 34, rotating the lever 33 above the exhaust pipe. Then, the lever 33 is driven to move downward by the vertical lever drive cylinder, causing the exhaust pipe to rotate downward, so that the exhaust pipe rotates to the designated position.

[0053] The present invention provides an adjuster position adjustment mechanism 13 between the infusion set long catheter straightening mechanism 15 and the third straightening mechanism 7.

The second claw drive moving assembly 32 is mounted on the frame 14. It can clamp both ends of the long tubing of the infusion set and straighten the long tubing of the infusion set by cooperating with the first straightening claw and the second straightening claw.

[0055] The steps for straightening the infusion set in Embodiments 1 and 2 of this invention are slightly different. When using this method, the appropriate step can be selected based on the current operational situation and the length of the infusion set, as shown in the attached diagram. Figure 7 This invention relates to an infusion set with an exhaust pipe for straightening operations. For ease of description, see attached Figure 7 The location is used to illustrate this; other attached diagrams can be referenced. Figure 7 , attached Figure 7 In the infusion set, from front to back, are: intravenous infusion needle, needle hub 5, long catheter 4, flow regulator 6 on long catheter 4, drip chamber 8, short catheter 10, vent tube 11, and medication needle. The vent tube 11 is connected to the short catheter 10 and medication needle. One end of the vent tube 11 is connected to the short catheter 10 and medication needle, while the other end is free, allowing the vent tube 11 to rotate around its connection point with the short catheter 10 and medication needle. In this invention, the first straightening mechanism 1 and the second straightening mechanism 2 can adopt existing technologies, such as the tail-end material handling mechanism and the head-end material handling mechanism in the background technology CN212048048U, which can realize the up-down, forward-backward, left-right movement of the first gripper 27 and the second gripper 30. The third straightening mechanism, the fourth straightening mechanism, and the adjuster position adjustment mechanism 13 are similar, and can realize the up-down, forward-backward, left-right movement of the grippers. In this invention, the second gripper drive cylinder 31 of the second gripper 30 is mounted on a support frame, which can move relative to the frame 14 in all directions (front, back, left, right, up, and down), as shown in the attached diagram. Figure 1 Appendix Figure 2 Appendix Figure 3In this invention, the third gripper drive cylinder 18, fourth gripper drive cylinder 21, fifth gripper drive cylinder 26, and horizontal or vertical lever drive cylinder of the lever for the third straightening mechanism 7, the fourth straightening mechanism 9, the adjuster position adjustment mechanism 13, and the exhaust pipe actuation mechanism 12 can all be mounted on the support frame. That is, the third gripper drive moving assembly, the fourth gripper drive moving assembly, the fifth gripper drive moving assembly, and the actuation drive moving assembly can share the second gripper drive moving assembly 32 of the second straightening mechanism 2. Furthermore, the front-to-back distance between the third gripper drive cylinder 18, the fourth gripper drive cylinder 21, and the fifth gripper drive cylinder 26 can also be adjusted by installing front-to-back movement drive cylinders. The third straightening mechanism 7, the fourth straightening mechanism 9, the adjuster position adjustment mechanism 13, and the exhaust pipe actuation mechanism 12 can also be set individually or in combination, as long as the movement of each gripper up, down, left, right, forward, and backward can be achieved. This invention can install a control system on the frame 14, such as a PLC control system. All straightening mechanisms, exhaust pipe actuation mechanisms, and regulator clamping mechanisms on the frame are controlled by the control system. The method for straightening an infusion set according to the present invention: Step 1: Drive the first gripper 27 and the second gripper 30 to grab the infusion set from the material conveying mechanism. One end of the long tubing 4 of the infusion set 3 extends forward through the gripping space formed by the two first straightening grippers and the other end extends backward through the gripping space formed by the two second straightening grippers. Drive the first gripper 27 and the second gripper 30 to move in opposite directions. The first gripper 27 moves forward along the long tubing 4 and the second gripper 30 moves backward along the long tubing 4 until the front end of the first gripper 27 abuts against the needle seat 5 and the rear end of the second gripper 30 abuts against the flow regulator 6, thus straightening the long tubing 4 of the infusion set 3. Step 2: Drive the third gripper 17 to grab the part between the flow regulator 6 and the dripping bucket 8. The width of the space after the two third straightening claws of the third gripper 17 are closed is greater than the outer diameter of the dripping bucket 8, so that the third gripper 17 can slide through the dripping bucket 8. Step 3: Drive the two second straightening claws of the second clamping claw 30 to open, drive the first clamping claw 27 to move forward, the front end of the first clamping claw 27 abuts against the needle seat 5, and can pull the infusion set 3 forward as a whole, so that the drip chamber 8 passes through the third clamping claw 17, that is, at this time the drip chamber 8 is located at the front end of the third clamping claw 17. Step 4: Drive the fourth gripper 20 to approach the third gripper 17, and the fourth gripper 20 will grasp the short tube 10; Step 5: Drive the fourth clamp 20 to move backward. The fourth clamp 20 moves backward along the short tube 10 until it stops at the part where the rear end of the fourth clamp 20 connects with the rear end of the short tube 10, the exhaust pipe 11, and the medicine needle. The rear end of the fourth clamp 20 abuts against the exhaust pipe 11 and the medicine needle. The fourth clamp 20 continues to move backward because the long tube 4 has been straightened and the front end of the first clamp 27 abuts against the needle seat 5. The fourth clamp 20 moves backward and abuts against the exhaust pipe 11, cooperating with the first clamp 27 to straighten the short tube 10.

[0056] In this invention, there are two methods to adjust the exhaust pipes of the infusion set to a designated state. The designated state can be a downward hanging state or another designated state, such as a horizontal state, which can be set according to the needs. One method is to drive the first gripper 27 and the fourth gripper 20 to move relative to each other, so that the infusion set 3 is in a relaxed state, and the exhaust pipe 11 hangs down under its own gravity, forming a natural hanging state. The other method is to use an exhaust pipe actuation mechanism, which uses a lever 33 or a pressing lever 24 to press down the exhaust pipe and rotate it to a designated state, such as a horizontal state or a hanging state. The two methods can be selected according to the needs. This invention also includes a flow regulator position adjustment operation, so as to adjust the position of the flow regulator 6 on the long tubing 4 according to the packaging requirements. Compared with the prior art, this invention can realize the straightening operation of the infusion set with exhaust pipes and can adjust all the exhaust pipes to the same designated position or state, so that all the exhaust pipes are orderly, thus further improving the efficiency of the subsequent winding operation.

[0057] Example 3 As attached Figure 8-12 The present invention can also be used to straighten the long and short catheters of the Y-type three-way infusion set 42. For ease of description, this embodiment is illustrated in the appendix. Figure 13 To illustrate using location, see attached. Figure 13 The existing Y-type three-way infusion set 42 has a three-way long catheter 43 in the middle, a first short catheter 44 at an angle in front, and a second short catheter 45 at the same horizontal level as the three-way long catheter 43 at the rear. A method for straightening an infusion set, characterized by comprising the following steps: Step 1: Long tubing straightening operation: The long tubing straightening mechanism 15 on the drive frame 14 grabs the long tubing of the infusion set and straightens it; Step 2: Short tube straightening operation: The short tube straightening mechanisms 35 on the front and rear sides of the drive frame 14 respectively grab the first short tube 44 and the second short tube 45 of the Y three-way infusion set 42 and straighten them respectively.

[0058] Specifically: Step 1: Straightening the three-way long tubing 43: Drive the first gripper 27 and the second gripper 30 to grab the three-way long tubing 43 of the Y-type three-way infusion set 42 from the material conveying mechanism, drive the first straightening mechanism 1 to move away from the second straightening mechanism 2, or drive the second straightening mechanism 2 to move away from the first straightening mechanism 1, or drive the first straightening mechanism 1 and the second straightening mechanism 2 to move in opposite directions simultaneously. As attached Figure 13 When the flow regulator of the Y-type three-way infusion set 42 moves away from the drip chamber, the grippers of the first straightening mechanism 1 and the second straightening mechanism 2 move away from each other. After the first straightening mechanism 1 and the second straightening mechanism 2 move away from each other, the front end of the first gripper 27 abuts against the flow regulator of the Y-type three-way infusion set 42, and the rear end of the second gripper 30 abuts against the drip chamber of the Y-type three-way infusion set 42, straightening the three-way long tube 43 of the Y-type three-way infusion set 42. Under the action of gravity, the first short tube 44 on the front side of the three-way long tube 43 tilts downward. When the flow regulator of the infusion set 3 approaches the drip chamber, the grippers of the first straightening mechanism 1 and the second straightening mechanism 2 grasp the three-way long tube 43 between the flow regulator and the first short tube 44. The first straightening mechanism 1 and the second straightening mechanism 2 move away from each other. The grippers of the first straightening mechanism 1 abut against the end of the three-way long tube 43 near the first short tube 44. The grippers of the second straightening mechanism 2 abut against the flow regulator, moving the flow regulator closer to the drip chamber. The outer end of the grippers of the second straightening mechanism 2 abuts against the flow regulator, straightening the three-way long tube 43 of the Y three-way infusion set 42. Under the action of gravity, the first short tube 44 on the front side of the three-way long tube 43 tilts downward. Step 2: Grasp the flow regulator: When the front end of the first gripper 27 abuts against the flow regulator of the Y-three-way infusion set 42 and the rear end of the second gripper 30 abuts against the drip chamber of the Y-three-way infusion set 42, drive the fifth gripper 25 to open and grab the flow regulator of the Y-three-way infusion set 42 to fix the position of the flow regulator in preparation for grabbing the first short catheter 44; Step 3: Straightening the first short conduit 44: Drive the short conduit straightening mechanism 35 in front of the first gripper 27. In the initial state, adjust the angle of the short conduit gripper 36 in the short conduit straightening mechanism 35 in front of the first gripper 27 according to the tilt angle of the first short conduit 44. By adjusting the drive motor 40 to drive the adjustment plate 41 to rotate, the adjustment plate 41 drives the short conduit gripper drive cylinder 37 to rotate, thereby changing the tilt angle of the short conduit gripper 36. After the three-way long conduit 43 is straightened, the short conduit gripper 36 opens and can just grab the first short conduit 44. Then drive the short conduit gripper drive moving component to move the first short conduit 44 away from the first gripper 27 until the front end of the short conduit gripper 36 abuts against the needle seat at the front end of the first short conduit 44, straightening the first short conduit 44. Step 4: Straightening the second short conduit 45: Drive the short conduit straightening mechanism on the rear side of the second gripper 30, the short conduit gripper opens, grabs the second short conduit, and the short conduit gripper drive moving component drives the second gripper 30 to move backward along the second short conduit 45 until the short conduit gripper abuts against the fixed seat at the rear end of the second short conduit 45, straightening the second short conduit 45.

[0059] The infusion set straightening device using the above-mentioned infusion set straightening method includes a frame 14, on which a long infusion set tubing straightening mechanism 15 is provided. The device is characterized in that a short tubing straightening mechanism 16 is provided on the frame 14. The short tubing straightening mechanism 16 is mounted on the frame 14. The grippers of the short tubing straightening mechanism 16 grasp the short tubing and cooperate with the long infusion set tubing straightening mechanism 15 to straighten the short tubing, thereby achieving the straightening of the entire infusion set.

The short tube straightening mechanism 35 includes a short tube clamp 36, a short tube clamp drive cylinder 37, and a short tube clamp drive moving assembly. The infusion set long catheter straightening mechanism 15 has a short tube clamp 36 on at least one side. The short tube clamp 36 includes a short tube straightening claw 38 that opens and closes relative to each other. The short tube straightening claw 38 is driven by the short tube clamp drive cylinder 37, which is driven by the short tube clamp drive moving assembly. The short tube drive moving assembly is mounted on the frame 14 so that the short tube straightening mechanism can grasp the short catheter of the infusion set, and the infusion set long catheter straightening mechanism can cooperate to straighten the short catheter.

[0061] The short tube clamp 36 of the present invention is inclined and tilted downward toward the infusion set long catheter straightening mechanism 15, so as to grab the inclined short catheter on the infusion set and straighten it.

[0062] The present invention provides a short pipe gripper tilt adjustment mechanism 39 between the short pipe gripper drive cylinder 37 and the short pipe gripper drive moving assembly. The short pipe gripper tilt adjustment mechanism 39 includes an adjustment drive motor 40 and an adjustment plate 41. The adjustment drive motor 40 is located above the short pipe gripper drive cylinder 37. The adjustment plate 41 is fixedly mounted on the output shaft of the adjustment drive motor 40. The adjustment plate 41 is fixedly connected to the short pipe gripper drive cylinder 37. The adjustment drive motor 40 is driven by the short pipe gripper drive moving assembly so that the adjustment plate 41 is driven to rotate through the adjustment drive motor 40. The adjustment plate 41 drives the short pipe gripper drive cylinder 37 to rotate, thereby changing the tilt angle of the short pipe gripper 36.

[0063] The infusion set long catheter straightening mechanism 15 of the present invention has an adjuster position adjustment mechanism 13 on one side. The adjuster position adjustment mechanism 13 includes a fifth gripper 25, a fifth gripper drive cylinder 26, and a fifth gripper drive moving assembly. The fifth gripper 25 is provided on one side of the third straightening gripper. The fifth gripper 25 includes a fifth adjuster clamping gripper that opens and closes relative to each other. The fifth adjuster clamping gripper is driven by the fifth gripper drive cylinder 26, which is driven by the fifth gripper drive moving assembly. The fifth gripper drive moving assembly is mounted on the frame 14 so as to clamp the flow regulator of the infusion set through the fifth adjuster clamping gripper and move it along the long catheter to adjust the position of the flow regulator on the long catheter.

[0064] The infusion set long catheter straightening mechanism 15 of the present invention includes a first straightening mechanism 1 and a second straightening mechanism 2. The first straightening mechanism 1 includes a first gripper 27, a first gripper drive cylinder 28, and a first gripper drive moving assembly 29. The second straightening mechanism 2 includes a second gripper 30, a second gripper drive cylinder 31, and a second gripper drive moving assembly 32. The first gripper 27 and the second gripper 30 are spaced apart below the frame 14. The first gripper 27 includes a first straightening claw that opens and closes relative to each other. The first straightening claw is driven by the first gripper drive cylinder 28. The first gripper drive cylinder 28 is driven by the first gripper drive moving assembly 29, which is mounted on the frame 14. The second gripper 30 includes a relatively opening and closing second straightening gripper, which is driven by the second gripper drive cylinder 31, which is driven by the second gripper drive moving assembly 32, which is mounted on the frame 14. The two grippers work together to clamp both ends of the long tubing of the infusion set and straighten the long tubing of the infusion set.

[0065] When it is necessary to straighten both short tubings on the Y-type three-way infusion set 42, in this embodiment, two short tubing straightening mechanisms 35 can be installed on the frame 14, respectively located in front of and behind the long tubing straightening mechanism 15. The front one is a short tubing straightening mechanism 35 with a short tubing clamp tilt adjustment mechanism 39, used to straighten the tilted first short tubing 44 in front of the Y-type three-way infusion set 42. The rear one is a short tubing straightening mechanism 35 without a short tubing clamp tilt adjustment mechanism 39, used to straighten the second short tubing 45 behind the Y-type three-way infusion set 42. In this invention, the first... The straightening mechanism 1 and the second straightening mechanism 2 can adopt existing technologies, such as the tail material handling mechanism and head material handling mechanism in the background technology CN212048048U, which can realize the up, down, forward, backward, left and right movement of the first gripper 27 and the second gripper 30. The short pipe straightening mechanism 16 and the regulator position adjustment mechanism 13 have short pipe gripper drive moving components and fifth gripper drive moving components that are similar to the first gripper drive moving component 29 and the second gripper drive moving component 32, which can realize the up, down, forward, backward, left and right movement of the short pipe gripper 36 and the fifth gripper 25, as shown in the attached figure. Figure 9-11 The fifth gripper drive cylinder 26, the first gripper drive cylinder 28, and the adjusting drive motor 40 can be installed on the same gripper connecting seat. The gripper connecting seat is driven by the first gripper drive moving component 29. That is, the fifth gripper drive moving component and the short pipe gripper drive moving component of the short pipe straightening mechanism 35 for straightening the first short conduit 44 can be the same drive moving component as the first gripper drive moving component 29. In this case, because the short pipe gripper 36 connected to the drive motor 40 needs to move relative to the first gripper 27, the drive motor 40 can be slidably connected to the gripper connecting seat through the horizontal drive cylinder. The fifth gripper drive moving component, the short pipe gripper drive moving component of the short pipe straightening mechanism 35 for straightening the first short conduit 44, and the first gripper drive moving component 29 can also be set separately and installed according to requirements. Correspondingly, as shown in the attached... Figure 9 , 10The short tube clamp drive cylinder 37 of the short tube straightening mechanism 35 for straightening the second short catheter 45 behind the Y-type three-way infusion set 42 can be mounted on the same drive cylinder connecting seat as the second clamp drive cylinder 31. This drive cylinder connecting seat is driven by the second clamp drive moving assembly 32. That is, the short tube clamp drive moving assembly of the short tube straightening mechanism 35 for straightening the second short catheter 45 behind the Y-type three-way infusion set 42 can be the same drive moving assembly as the second clamp drive moving assembly 32. At this time, because the short tube clamp for straightening the second short catheter 45 needs to move relative to the second clamp 30. Therefore, a horizontal drive cylinder can be set on the short pipe clamp drive cylinder 37 used to straighten the second short conduit 45, so that the short pipe clamp drive cylinder 37 used to straighten the second short conduit 45 is slidably connected to the drive cylinder connecting seat via the horizontal drive cylinder. The short pipe clamp drive moving component of the short pipe straightening mechanism 35 used to straighten the second short conduit 45 and the second clamp drive moving component 32 can also be different drive moving components, which can be installed as needed. The present invention can set a control system on the frame 14, such as a PLC control system. All straightening mechanisms and regulator clamping mechanisms on the frame are controlled by the control system.

[0066] This invention is applicable not only to the straightening of conventional infusion sets, but also to the straightening of Y-type three-way infusion sets, greatly expanding the scope of application of this invention.

[0067] Due to the above-mentioned structure, this invention has the advantages of ingenious structure, the infusion set can be straightened as a whole, high feeding efficiency, adjustable exhaust pipe direction, convenient subsequent winding operation, and the ability to straighten inclined short tubing.
