Description

Technical Field

[0001] This utility model relates to the field of PTFE tube cutting technology, and in particular to a PTFE tube cutting device. Background Technology

[0002] PTFE tubing, also known as polytetrafluoroethylene tubing or simply F4 tubing, is a high molecular polymer, commonly referred to as the "king of plastics." It is characterized by its white, waxy, and translucent appearance, and possesses excellent heat and cold resistance. During the production process, PTFE tubing sometimes needs to be cut. Existing cutting devices are not convenient for simultaneously cutting multiple PTFE tubings, resulting in low cutting efficiency. Furthermore, they are not convenient for adjusting the cutting length of the PTFE tubing. Therefore, those skilled in the art provide a PTFE tubing cutting device to solve the problems mentioned in the background art. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection", and "setting" should be interpreted broadly. For those skilled in the art, the specific meaning of the above terms in this patent can be understood according to the specific circumstances.

[0020] Reference Figures 1-5 A PTFE tube cutting device includes a base plate 1, a support frame 2 fixed on the base plate 1 by bolts, a cutting assembly for cutting PTFE tubes on the support frame 2, a positioning plate 3 fixed on the base plate 1 by bolts, and the positioning plate 3 is located on one side of the cutting assembly. The side of the positioning plate 3 has multiple positioning holes 4, through which multiple PTFE tubes are passed respectively. The support frame 2 is provided with a material blocking assembly, and the support frame 2 is provided with a locking assembly for controlling the position of the material blocking assembly.

[0021] In this invention, the cutting assembly includes a first cutter head 8, a second cutter head 9, a first electric push rod 7, and a second electric push rod 10. The first cutter head 8 and the second cutter head 9 are both slidably connected to the support frame 2. The first electric push rod 7 is fixed to the base plate 1 by bolts, and one end of the first electric push rod 7 is fixed to the first cutter head 8. The second electric push rod 10 is fixed to the top of the support frame 2 by bolts, and one end of the second electric push rod 10 is fixed to the second cutter head 9. When the first electric push rod 7 and the second electric push rod 10 are activated, they extend synchronously, causing the first cutter head 8 and the second cutter head 9 to move towards each other and contact the PTFE tubes, thereby achieving simultaneous cutting of multiple PTFE tubes at one time.

[0022] In this utility model, the material blocking assembly is a top plate 5, and guide rods 14 are slidably connected through both sides of the support frame 2. The top plate 5 is fixed to the ends of the two guide rods 14 by bolts, and the top plate 5 is located between the first cutter head 8 and the second cutter head 9. Multiple PTFE tubes pass through each positioning hole 4 and the cutting operation can begin when one end of the PTFE tube contacts the top plate 5.

[0023] In this invention, the locking component is a magnetic ring 15. Sliding rods 11 are slidably connected to both sides of the support frame 2. A magnetic ring 15 is fixed to one end of each sliding rod 11 by bolts, and the magnetic ring 15 is attracted to the guide rod 14. Springs 12 are sleeved on the outer circumference of both sliding rods 11, and the two ends of the springs 12 are fixed to the sliding rods 11 and the support frame 2, respectively. Multiple scale lines 13 are provided on the side of the guide rod 14. When adjusting the cutting length of the PTFE tube, the two sliding rods 11 are pulled outwards. The sliding rods 11 move outwards, causing the magnetic ring 15 to disengage from the guide rod 14. The springs 12 contract under force, and then the top plate 5 is pulled to move the guide rod 14. The movement distance of the top plate 5 can be determined by observing the scale lines 13. After determining the position, the sliding rods 11 are released, and the springs 12 return to their original position, causing the magnetic ring 15 to re-attract to the guide rod 14, thus locking the guide rod 14.

[0024] In this utility model, a discharge plate 6 is fixed to one side of the base plate 1 by bolts, and the discharge plate 6 is set at an angle. The cut PTFE tubes fall onto the discharge plate 6 and then roll out through the discharge plate 6.

[0025] Working principle: When it is necessary to cut PTFE tubes, multiple PTFE tubes are passed through each positioning hole 4 so that one end of the PTFE tube contacts the top plate 5. At this time, the PTFE tube is located between the first cutter head 8 and the second cutter head 9. The first electric push rod 7 and the second electric push rod 10 are activated. The first electric push rod 7 and the second electric push rod 10 extend synchronously, causing the first cutter head 8 and the second cutter head 9 to move towards each other and contact the PTFE tube, so as to achieve simultaneous cutting of multiple PTFE tubes at one time. The cut PTFE tubes fall onto the discharge plate 6 and are then discharged by rolling through the discharge plate 6.

[0026] When adjusting the cutting length of the PTFE tube, pull the two slide rods 11 outwards respectively. The slide rods 11 move outwards, causing the magnetic ring 15 to disengage from the guide rod 14. The spring 12 contracts under force. Then, pull the top plate 5 to move the guide rod 14. The movement distance of the top plate 5 can be determined by observing the scale line 13. After determining the position, release the slide rods 11. The spring 12 rebounds and resets, causing the magnetic ring 15 to re-attract the guide rod 14, thus locking the guide rod 14. When the PTFE tube contacts the adjusted top plate 5, it can be cut again.

[0027] In this application, the structures and connections not described in detail are all prior art, and their structures and principles are well known, so they will not be described in detail here.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
