[0002] A blood collection chair is a specialized chair designed for medical institutions, used by healthcare professionals to collect blood from patients or blood donors. The structural frame of a blood collection chair is typically made of metal tubing, commonly including but not limited to stainless steel and aluminum alloy tubing. These materials possess excellent mechanical properties and corrosion resistance, making them suitable for the demands of medical environments. During production, these tubing materials undergo precise cutting, bending, and welding processes to form the blood collection chair frame components that meet design requirements. The tubing cutting and blanking equipment used in blood collection chair production is specifically designed for processing these tubing materials, aiming to improve production efficiency and product quality.

[0003] Existing tube cutting devices for blood collection chair production typically rely on manual placement of tubes one by one to the cutting station, resulting in low work efficiency. Although some devices are electrically driven, each process needs to be started in stages, leading to time delays between processes and poor production continuity. Summary of the Invention

Detailed Implementation

[0030] The invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are illustrated. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0031] A tube cutting device for the production of blood collection chairs, such as Figures 1-12As shown, the system includes a base 1, a support frame 2, a limiting block 3, an electric guide rail 4, a transport frame 5, a push rod 6, a connector 7, a lifting frame 8, a first connecting rod 9, a first elastic element 10, a lifting plate 11, a slide table 17, a mounting plate 23, and a collection frame 34. The base 1 has a support frame 2 and an electric guide rail 4 on its top. The support frame 2 is designed as an inclined plane, and the electric guide rail 4 is located at the bottom of the support frame 2. A limiting block 3 is located in the middle of the top of the support frame 2, used to position the pipe. Several first connecting rods 9 are located at the bottom of the support frame 2, and the lifting frame 8 is slidably connected to each of the first connecting rods 9. A lifting plate 11 is located at the top of the upper first connecting rod 9, below and behind the limiting block 3. A first elastic element 10 is located on the outer side of the upper first connecting rod 9, connecting the lifting frame 8 and the lifting plate 11. The first elastic element 10 allows the lifting frame 8 to quickly return after lifting a pipe. Returning to its original position, ready for the next lifting action, the base 1 has a conveying frame 5 on top, which is located above the electric guide rail 4. The moving part of the electric guide rail 4 is connected to a push rod 6 and a connector 7. The bottom of the conveying frame 5 has a through groove for the push rod 6 to move. The top of the connector 7 has an inclined block, and the side of the inclined block near the left end of the lifting frame 8 is designed as an inclined surface. The top right side of the base 1 is slidably connected to a slide table 17. The top right side of the base 1 has a collection frame 34. The slide table 17 has a cutting mechanism, and the collection frame 34 has a mounting plate 23. A fixing mechanism is provided between the cutting mechanism and the mounting plate 23. The slide table 17 is located to the right of the electric guide rail 4, and the collection frame 34 is located behind the slide table 17. The top of the support frame 2 has a feeding hopper 37, which is used to stack multiple pipes into the feeding hopper 37 to achieve automatic continuous feeding. The bottom front side of the feeding hopper 37 has a limiting plate 38, which can prevent the pipes from sliding out during the feeding process.

[0032] like Figure 5 As shown, the cutting mechanism includes a cylinder 18, a mounting bracket 19, an abrasive wheel cutter 20, a dual-axis motor 21, and a third threaded rod 22. Three mounting brackets 19 are provided on the top of the slide table 17, each mounting abrasive wheel cutter 20. The middle mounting bracket 19 is fixedly connected to the slide table 17, while the mounting brackets on either side are slidably connected to the slide table 17. Two cylinders 18 are provided on the top of the base 1, located on the left and right sides of the slide table 17 respectively, with their extension rods connected to the slide table 17. A dual-axis motor 21 is located in the center of the top of the slide table 17. 1. Two third threaded rods 22 with opposite directions of rotation are connected to the two output shafts of the dual-axis motor 21. The two third threaded rods 22 are respectively threaded to the mounting brackets 19 on both sides. When cutting, the abrasive wheel cutter 20 and the cylinder 18 are started. The cylinder 18 will drive the slide table 17 to move closer to the pipe. Then the abrasive wheel cutter 20 cuts the pipe. When the length of each section of the cut pipe needs to be adjusted, the dual-axis motor 21 can be started to adjust the mounting brackets 19 on both sides to adjust the distance between the abrasive wheel cutters 20 on both sides and the abrasive wheel cutter 20 located in the middle.

[0033] like Figure 7 and Figure 8 As shown, the fixing mechanism includes a top frame 27, a movable plate 28, a connecting plate 29, a second connecting rod 30, a second elastic element 31, and a support plate 39. Two support plates 39 are provided on the front side of the mounting plate 23. A sliding groove is formed on the support plate 39, and the movable plate 28 is slidably connected to the groove. A second connecting rod 30 is provided at the rear end of the movable plate 28. A connecting plate 29 is provided at the end of the second connecting rod 30 away from the movable plate 28. A second elastic element 31 is provided on the outer side of the second connecting rod 30. The second elastic element 31 provides appropriate elastic support when the top frame 27 pushes the movable plate 28, ensuring the pipe is stably secured. While ensuring a secure clamping effect, the second elastic element 31 is connected between the moving plate 28 and the connecting plate 29 to prevent damage to the pipe due to excessive pressure. The mounting bracket 19 in the middle is provided with top brackets 27 on both sides. The position of the top brackets 27 corresponds to the lower part of the moving plate 28. As the abrasive wheel cutter 20 moves towards the pipe, the top brackets 27 will move closer to the moving plate 28. The top brackets 27 will contact the lower part of the moving plate 28 and push the moving plate 28 to slide along the groove, thereby driving the connecting plate 29 to move towards the mounting plate 23, thus clamping the pipe and providing stable support and fixation.

[0034] like Figure 7 and Figure 9 As shown, it also includes a protective shell 24, a limiting rod 25, a connecting shaft 26, and a limiting seat 40. Each mounting bracket 19 has a connecting shaft 26 on its right side. The protective shell 24 is rotatably sleeved on the outside of the connecting shaft 26. The protective shell 24 is located outside the abrasive wheel cutter 20. The limiting rod 25 is connected between the three protective shells 24. The limiting seat 40 is provided on the top of the base 1. The height of the opening of the limiting seat 40 corresponds to the limiting rod 25. When cutting begins, the limiting rod 25 will move into the limiting seat 40. At this time, the limiting seat 40 can lock the limiting rod 25 to prevent the protective shell 24 from being accidentally opened during the movement.

[0035] like Figure 10 As shown, the connecting shaft 26 has a groove 32, and the connection between the protective shell 24 and the connecting shaft 26 is provided with a protrusion 33. The protrusion 33 fits into the groove 32, and the groove 32 and the protrusion 33 can limit the rotation angle of the protective shell 24.

[0036] like Figure 4As shown, it also includes a second threaded rod 15, a nut plate 151, and a turntable 16. The support frame 2 includes a fixed frame 201 and a movable frame 202. The fixed frame 201 is provided at the top of the base 1, and the movable frame 202 is slidably connected inside the fixed frame 201. The nut plate 151 is provided at the bottom of the fixed frame 201, and the second threaded rod 15 is threadedly connected inside the nut plate 151. The bottom of the movable frame 202 is provided with a bearing seat 42, which is sleeved on the outside of the second threaded rod 15. The turntable 16 is provided on the left side of the second threaded rod 15. When it is necessary to adapt to pipes of different lengths, the turntable 16 can be rotated to drive the second threaded rod 15 to rotate, thereby adjusting the position of the movable frame 202 and thus adjusting the overall length of the support frame 2.

[0037] like Figure 2 and Figure 3 As shown, it also includes a fixed connecting plate 111, a sliding plate 12, a rotary motor 121, a first threaded rod 13, and a guide rod 14. The bottom of the lifting plate 11 is provided with a fixed connecting plate 111, and the first threaded rod 13 is threadedly connected to the fixed connecting plate 111. The sliding plate 12 is slidably connected to the lifting plate 11. The sliding plate 12 is an L-shaped plate, which can simultaneously block the movement of the pipe located behind the sliding plate 12 when it rises. The front side of the sliding plate 12 is provided with a rotary motor 121 and a guide rod 14. The output shaft of the rotary motor 121 is connected to the first threaded rod 13. The guide rod 14 passes through the fixed connecting plate 111. When it is necessary to adapt to pipes of different sizes, the first threaded rod 13 can be rotated by the rotary motor 121 to adjust the position of the sliding plate 12, thereby adjusting the width of the lifting plate 11 so that the lifting plate 11 can support pipes of different sizes.

[0038] like Figure 12 As shown, it also includes a drawer 36 and a filter screen 35. The collection frame 34 is slidably connected to the drawer 36. The filter screen 35 is provided on the inner side of the collection frame 34. The mounting plate 23 is located above the collection frame 34. After the pipe is cut, the pipe will move along the filter screen 35 to the rear side of the collection frame 34, and the debris on the pipe will fall from the filter screen 35 to the drawer 36.

[0039] like Figure 8 As shown, it also includes a rubber pad 41. The front side of the mounting plate 23 is provided with a rubber pad 41. The rubber pad 41 increases the friction to enhance the fixing effect on the pipe.

[0040] In use, the blood collection chair tubing is placed into the hopper 37. The tubing will fall along the inclined surface of the hopper 37 into the support frame 2, and then slide along the inclined surface of the support frame 2 to the back of the limiting block 3. One tubing is then placed into the transport frame 5. Then, the electric guide rail 4 is started. The electric guide rail 4 performs one reciprocating motion. The electric guide rail 4 first drives the push rod 6 to move to the right to transport the tubing to the cutting mechanism. Then, the push rod 6 is moved back to its original position. When the moving part of the electric guide rail 4 moves to the left, it will simultaneously drive the connecting part 7 to move to the left. The inclined block on the connecting part 7 will contact the lifting frame 8 and push the lifting frame 8 upwards at an incline. When the lifting frame 8 rises, it lifts the next tubing, making it pass the limiting block 3 and move along the inclined surface to the transport frame 5 to prepare for the next round of cutting.

[0041] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
