[0030] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0031] Please refer to Figures 1 to 6As shown, the utility model designs a clamping and cutting device for FEP heat shrinkable tubes, which includes a first clamping mechanism 2 and a cutting mechanism 1, wherein the cutting mechanism 1 includes a first driving member 11 and a cutting member 12, wherein the first driving member 11 is used to drive the cutting member 12 to cut the FEP heat shrinkable tube; wherein the first clamping mechanism 2 includes a second driving member 21, a limiting member 22 and a clamping member 23, wherein the output end of the second driving member 21 is rotatably connected to the clamping member 23, and the clamping member 23 is also rotatably connected to the limiting member 22, so as to drive the clamping member 23 to rotate around the limiting member 22, and clamp the FEP heat shrinkable tube between the clamping member 23 and the limiting member 22.

[0032] In the above technical solution of the utility model, the clamping and cutting device abandons all the existing traditional forms of manual grasping and cutting of FEP heat shrink tubes. It uses its own clamping mechanism to effectively clamp the FEP heat shrink tube, and enables the clamped FEP heat shrink tube to take the material from the wet expander or the dry expander. After the FEP heat shrink tube is cooled, the FEP heat shrink tube is cut off and rolled up by its own cutting mechanism, thereby greatly improving the degree of automation in the production of FEP heat shrink tubes. It does not require manual operation and can improve production efficiency and production quality.

[0033] Furthermore, the clamping and cutting device described in the present invention further comprises a second clamping mechanism 3, wherein the second clamping mechanism 3 comprises two stoppers 31 arranged opposite to each other, and the distance between the two stoppers 31 is the diameter of the FEP heat shrink tube.

[0034] In order to ensure that the cutting mechanism 1 can drive its cutting piece 12 to cut the FEP heat shrink tube more accurately and stably, in the above technical solution of the utility model, a second clamping mechanism 3 can also be provided, and the second clamping mechanism 3 and the first clamping mechanism 2 are respectively provided at both ends of the cutting mechanism 1, that is, the first clamping mechanism 2, the cutting mechanism 1 and the second clamping mechanism 3 can be provided in sequence along the feeding direction of the FEP heat shrink tube. At this time, when the cutting mechanism 1 is used to cut the FEP heat shrink tube, the first clamping mechanism 2 and the second clamping mechanism 3 can clamp the FEP heat shrink tube accordingly.

[0035] It should be pointed out that the distance between the two stoppers 31 arranged opposite to each other on the above-mentioned second clamping mechanism 3 is manually adjustable, and the operator can control the distance between the two stoppers 31 to be the diameter of the FEP heat shrink tube, so that the second clamping mechanism 3 can stably clamp the above-mentioned FEP heat shrink tube.

[0036] Furthermore, in the clamping and cutting device described in the present invention, the second clamping mechanism 3 further includes a mounting block 32 , and the mounting block 32 is provided with two mounting posts 33 arranged opposite to each other, and the mounting posts 33 are used to mount the stopper 31 .

[0037] Furthermore, in the clamping and cutting device described in the present invention, the stopper 31 includes a bolt 311 and a flexible pad 312 , the bolt 311 is threadedly connected to the mounting post 33 , and one end of the bolt 311 passes through the mounting post 33 and is connected to the flexible pad 312 .

[0038] In the above technical solution of the utility model, in order to facilitate the installation and adjustment of the gap between the two stoppers 31 arranged opposite to each other, in actual application, the stopper 31 can be specifically arranged to include a bolt 311 and a flexible pad 312, and the bolt 311 can be controlled to be threadedly connected to the mounting column 33, and one end of the bolt 311 passes through the mounting column 33 and is connected to the above-mentioned flexible pad 312. At this time, the flexible pads 312 of the two stoppers 31 arranged opposite to each other are close to each other, and the distance between the two is the diameter of the FEP heat shrink tube.

[0039] Of course, since the above-mentioned bolt 311 is threadedly connected to the mounting column 33, during actual setting, the bolt 311 can be adjusted in real time according to the FEP heat shrink tubes of different diameters to be produced to adjust the distance between the two stoppers 31, thereby better clamping the FEP heat shrink tube.

[0040] Furthermore, in the clamping and cutting device described in the present invention, the flexible pad 312 is a silicone pad.

[0041] Furthermore, the clamping and cutting device described in the present invention further includes a bracket 4 and a driving device 5 arranged on the bracket 4, and the first clamping mechanism 2, the cutting mechanism 1 and the second clamping mechanism 3 are all arranged at the output end of the driving device 5.

[0042] Furthermore, in the clamping and cutting device described in the present invention, there is an angle between the driving direction of the driving device 5 and the horizontal direction.

[0043] It should be noted that in actual application, in order to facilitate use, the clamping and cutting device is also provided with a bracket 4 and a driving device 5 arranged on the bracket 4. The above-mentioned bracket 4 can be used to connect and match with external equipment, and the above-mentioned driving device 5 can be used to drive and adjust the positions of the first clamping mechanism 2, the cutting mechanism 1 and the second clamping mechanism 3 to meet the use requirements under different conditions.

[0044] In actual application, the operator can set and control the driving direction of the driving device 5 to have an angle with the horizontal direction. At this time, the first clamping mechanism 2, the cutting mechanism 1 and the second clamping mechanism 3 can be set at an angle to the horizontal direction to better clamp and cut the FEP heat shrink tube.

[0045] Furthermore, the clamping and cutting device described in the present invention further includes a guide rod 6, one end of which is connected to the bracket 4, and the other end of which extends from the bracket 4 and is used to support the FEP heat shrink tube.

[0046] In the above technical scheme of the utility model, in actual application, in some preferred embodiments, considering that the FEP heat shrinkable tube may be too long and may not be able to enter the first clamping mechanism 2 and the cutting mechanism 1 well after being discharged, a guide rod 6 may be pre-arranged on the clamping and cutting device, one end of which is connected to the bracket 4, and the guide rod 6 can be used to support the FEP heat shrinkable tube, so that the FEP heat shrinkable tube can be directly, simply and accurately transported to the appropriate positions of the first clamping mechanism 2 / second clamping mechanism 3 and the cutting mechanism 1 after being guided and supported by the guide tube after being discharged.

[0047] Furthermore, in the clamping and cutting device described in the present invention, the guide rod 6, the first clamping mechanism 2, the cutting mechanism 1 and the second clamping mechanism 3 are sequentially arranged along the feeding direction of the FEP heat shrink tube.

[0048] Furthermore, in the clamping and cutting device described in the present invention, the cutting piece 12 includes an upper blade 121 and a lower blade 122 which are arranged vertically up and down, and the upper blade 121 and the lower blade 122 are cross-hinged together through a pivot.

In actual application, there can be a hinge angle between the upper blade 121 and the lower blade 122, and the FEP heat shrink tube fed into the clamping and cutting device of the present invention can be correspondingly extended into the hinge angle (i.e., between the upper blade 121 and the lower blade 122). At this time, the first driving member 11 can be further controlled to work, so as to utilize the first driving member 11 to control and drive the upper blade 121 and the lower blade 122 to move closer to each other, thereby effectively cutting the FEP heat shrink tube.

[0050] Please refer to Figure 1 - Figure 6 , Embodiment 1 of the present utility model is:

[0051] A clamping and cutting device for an FEP heat shrinkable tube comprises a first clamping mechanism 2, a second clamping mechanism 3, a cutting mechanism 1, a bracket 4 and a driving device 5. The driving device 5 is arranged on the bracket 4, and a mounting plate is arranged at the output end of the driving device 5. The first clamping mechanism 2, the second clamping mechanism 3 and the cutting mechanism 1 are all arranged on the mounting plate at the output end of the driving device 5, and the first clamping mechanism 2, the cutting mechanism 1 and the second clamping mechanism 3 are arranged in sequence along the feeding direction of the FEP heat shrinkable tube.

At this time, the above-mentioned first clamping mechanism 2, the cutting mechanism 1 and the second clamping mechanism 3 are all inclined to the horizontal direction to better clamp and cut the FEP heat shrink tube.

[0053] like Figure 5 As shown, in this embodiment, the cutting mechanism 1 designed for the clamping and cutting device specifically includes a first driving member 11 and a cutting member 12, and the cutting member 12 includes an upper blade 121 and a lower blade 122 that are hinged to each other, and the upper blade 121 and the lower blade 122 are cross-hinged together through a pivot. In actual application, there is a hinge angle between the upper blade 121 and the lower blade 122, and the FEP heat shrink tube fed into the cutting mechanism 1 can be correspondingly extended into the hinge angle (i.e., between the upper blade 121 and the lower blade 122). At this time, the first driving member 11 can be further controlled to work, so as to use the first driving member 11 to control and drive the upper blade 121 and the lower blade 122 to move closer to each other, thereby effectively cutting the FEP heat shrink tube.

[0054] Accordingly, if Figure 6 As shown, in the present embodiment, the first clamping mechanism 2 comprises a second driving member 21, a limiting member 22 and a clamping member 23, wherein the clamping member 23 is specifically an L-shaped clamping member 23, and the output end of the second driving member 21 is rotatably connected to one end of the L-shaped clamping member 23, and the L-shaped clamping member 23 is also rotatably connected to the limiting member 22. At this time, the second driving member 21 can drive the L-shaped clamping member 23 to rotate around the limiting member 22, so that the other end of the L-shaped clamping member 23 cooperates with the limiting member 22 to clamp the FEP heat shrinkable tube, that is, the FEP heat shrinkable tube is clamped between the L-shaped clamping member 23 and the limiting member 22.

[0055] And, if Figure 5As shown, the second clamping mechanism 3 designed in this embodiment includes a mounting block 32 and two stoppers 31 arranged opposite to each other, the mounting block 32 is provided with two mounting posts 33 arranged opposite to each other, and each mounting post 33 is provided with a stopper 31. The stopper 31 includes a bolt 311 and a flexible pad 312, and the flexible pad 312 is specifically selected as a silicone pad. The bolt 311 is threadedly connected to the mounting post 33, and one end of the bolt 311 passes through the mounting post 33 and connects to the flexible pad 312, so that the flexible pads 312 of the two stoppers 31 are close to each other, and it is ensured that the spacing between the flexible pads 312 of the two stoppers 31 is finally equal to the diameter of the FEP heat shrink tube.

[0056] In addition, it should be noted that in the present embodiment, a guide rod 6 is further provided on the above-mentioned bracket 4. The guide rod 6 is used to play a guiding role. It is arranged upstream of the above-mentioned cutting mechanism 1 and the two clamping mechanisms, and one end of the guide rod 6 is connected to the bracket 4, and the other end of the guide rod 6 extends from the bracket 4 and is used to support the FEP heat shrinkable tube, so that the FEP heat shrinkable tube can be directly, simply and accurately transported to the appropriate positions of the first clamping mechanism 2 / the second clamping mechanism 3 and the cutting mechanism 1 after being guided and supported by the guide tube after being discharged.

[0057] From the above, it can be seen that the clamping and cutting device designed by the utility model optimizes its own structure, so that the clamping mechanism is used to effectively clamp the FEP heat shrink tube, and the FEP heat shrink tube is clamped to take the material from the wet expander or the dry expander, and after the FEP heat shrink tube is completely cooled, the FEP heat shrink tube is cut off and rolled up by its own cutting mechanism, thereby greatly improving the degree of automation in the production of FEP heat shrink tubes.
