Description

Technical Field

[0001] The utility model belongs to the technical field of polytetrafluoroethylene material processing devices, and in particular relates to a polytetrafluoroethylene rod slicing device. Background Art

[0002] Polytetrafluoroethylene is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene. This material has strong corrosion resistance. The advantages of polytetrafluoroethylene are not only reflected in its excellent corrosion resistance, but also in its high lubricity, non-adhesion, non-toxicity, electrical insulation, high temperature resistance and low temperature resistance. In addition, polytetrafluoroethylene also has good anti-aging resistance and has the best aging life among plastics. It is a polymer material with excellent performance and is widely used in chemical, electronic, medical and other fields. In the production and processing of polytetrafluoroethylene rods, slicing operations are often required. Traditional slicing methods mostly use manual operation or simple mechanical slicing, which has certain defects. For example, in the Chinese patent with publication number "CN 216731994 U", a device for slicing polytetrafluoroethylene rods is disclosed. When the device slices the polytetrafluoroethylene rod, a servo motor 1, a screw rod 1 and a slider are set to drive the stepper motor to move, so that the saw blade slices the polytetrafluoroethylene rod. By setting a servo motor 2, a screw rod 2, a slide plate, a cylinder 2, a lifting plate and an L-shaped push rod, the polytetrafluoroethylene rod placed in the rod slide rail can be pushed to the position of the saw blade. Since the device pushes the polytetrafluoroethylene rod from the end, after the polytetrafluoroethylene rod on the device is sliced, it is necessary to wait for the pushing structure to be completely reset before reloading, which increases the difficulty of slicing the polytetrafluoroethylene rod and reduces the slicing efficiency of the polytetrafluoroethylene rod.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-Figure 10 As shown, the utility model provides the following technical solutions:

[0032] A polytetrafluoroethylene rod slicing device comprises a pusher 8, the pusher 8 comprises two drive assemblies 88 symmetrically arranged in an upper and lower direction, and the drive assembly 88 comprises a guide part and a drive part rotatably connected to the guide part, and a moving channel for guiding the polytetrafluoroethylene rod to move along a preset direction is formed between the two guide parts;

[0033] The device also includes a slicing member for slicing the polytetrafluoroethylene rod material, and the slicing member is located at the discharge end of the moving channel.

[0034] Through the above technical scheme, when personnel need to slice the polytetrafluoroethylene rod, the polytetrafluoroethylene rod is placed between the two guide parts. After the polytetrafluoroethylene rod is placed, the driving part works, so that the driving part rotates relative to the circumference of the polytetrafluoroethylene rod, and the polytetrafluoroethylene rod is driven by the driving part to move between the two guide parts, so that the polytetrafluoroethylene rod moves toward the slicing part. When the polytetrafluoroethylene rod is under the slicing part, the slicing part works, so that the slicing part slices the polytetrafluoroethylene rod, and the polytetrafluoroethylene rod continues to move, so that the polytetrafluoroethylene rod continues to be sliced, and while slicing, personnel can also simultaneously place the polytetrafluoroethylene rod for loading.

[0035] Specifically, in one embodiment, regarding the above-mentioned guide portion:

[0036] like Figure 1-Figure 3 , Figure 5-Figure 6 , Figure 8-Figure 9As shown, the guide portion includes an arc-shaped plate 884, and the arc-shaped plate 884 is recessed toward one side of the polytetrafluoroethylene rod to form an arc-shaped groove 885.

[0037] In this embodiment, when personnel need to slice the polytetrafluoroethylene rod, the polytetrafluoroethylene rod is placed between the two arc plates 884. After the polytetrafluoroethylene rod is placed, the driving part works, so that the driving part rotates relative to the circumference of the polytetrafluoroethylene rod, and the polytetrafluoroethylene rod is driven by the driving part to move between the two arc plates 884, so that the polytetrafluoroethylene rod moves toward the slicing part. When the polytetrafluoroethylene rod is under the slicing part, the slicing part works, so that the slicing part slices the polytetrafluoroethylene rod, and the polytetrafluoroethylene rod continues to move, so that the polytetrafluoroethylene rod continues to slice. While slicing, personnel can also simultaneously place the polytetrafluoroethylene rod for loading. In addition, through the cooperation of the arc groove 885, the polytetrafluoroethylene rod moves more smoothly between the two arc plates 884.

[0038] In addition, in the present invention, how the driving part drives the polytetrafluoroethylene rod to move, such as Figure 1-Figure 3 , Figure 5-Figure 9 As shown, the driving part includes a driving roller 881, and a support seat 883 is fixedly connected to the side of the arc plate 884 facing away from the arc groove 885. The driving roller 881 is rotatably connected to the inside of the support seat 883, and a motor 882 is fixedly connected to the outside of the support seat 883, and the output end of the motor 882 is connected to the driving roller 881.

[0039] In this embodiment, after the polytetrafluoroethylene rod is placed between the two arc plates 884, the arc plates 884 support the motor 882 and the driving roller 881, and the motor 882 drives the driving roller 881 to rotate relative to the support seat 883, so that the driving roller 881 rotates relative to the circumference of the polytetrafluoroethylene rod, and the driving roller 881 drives the polytetrafluoroethylene rod to move between the two arc plates 884, so that the polytetrafluoroethylene rod moves toward the slicing part. When the polytetrafluoroethylene rod is under the slicing part, the slicing part works, so that the slicing part slices the polytetrafluoroethylene rod, and the polytetrafluoroethylene rod continues to move, so that the polytetrafluoroethylene rod continues to slice, and while slicing, personnel can also simultaneously place the polytetrafluoroethylene rod for loading, and in addition, through the cooperation of the arc groove 885, the polytetrafluoroethylene rod moves more smoothly between the two arc plates 884.

[0040] Furthermore, when the device drives the PTFE rod to move, in order to allow the device to be adjusted according to the specifications of the PTFE rod, such as Figure 1-Figure 3 , Figure 5-Figure 7As shown, the pusher 8 also includes a telescopic member, one side of the telescopic member is fixedly connected to one of the arc plates 884, and the other side of the telescopic member is fixedly connected to the other arc plate 884, and the two arc plates 884 are moved closer to or away from each other by the telescopic member.

[0041] In this embodiment, before personnel need to place the polytetrafluoroethylene rods, the telescopic parts work, thereby allowing the telescopic parts to drive the two arc plates 884 to move relative to each other, and then adjust the distance between the two arc plates 884, so that the device can drive polytetrafluoroethylene rods of different specifications to move, thereby increasing the scope of use of the device.

[0042] Specifically, in one embodiment, regarding the telescopic member:

[0044] In this embodiment, before personnel need to place polytetrafluoroethylene rods, the second electric push rod 83 works, and the first side plate 81 and the second side plate 89 cooperate to move the first support plate 82 relative to the second support plate 87, thereby adjusting the distance between the first support plate 82 and the second support plate 87. When the first support plate 82 and the second support plate 87 move, the two arc plates 884 are driven to move synchronously, thereby adjusting the distance between the two arc plates 884, so that the device can drive polytetrafluoroethylene rods of different specifications to move, thereby increasing the scope of use of the device.

[0045] In addition, in the present invention, in order to allow the number of polytetrafluoroethylene rods cut by the device to be adjusted, such as Figure 1-Figure 4 As shown, the device also includes a support assembly, the top of which is symmetrically fixedly connected to a support rod 6, a total of N pushers 8 are provided, N ≥ 1, and a connecting seat 85 is fixedly connected to the bottom of the pusher 8.

[0046] In this embodiment, the support rod 6 is supported by the support assembly. When personnel need to slice the polytetrafluoroethylene rod, the required number of pushers 8 are placed above the support rod 6, and the connection grooves 86 on the connecting seat 85 are engaged with the support rod 6, so that the required number of pushers 8 are installed on the support assembly, and the polytetrafluoroethylene rod is driven to move by the pushers 8, and the polytetrafluoroethylene rod is sliced ​​by the slicing piece, so that the device can slice the required number of polytetrafluoroethylene rods at the same time.

When the position of the connecting seat 85 is fixed, in order to further improve the tightness of the connecting seat 85 after adjustment, a rubber plate 810 is bonded to one end of the limit screw 84 extending to the inside of the connecting groove 86.

[0049] Specifically, in one embodiment, regarding the above-mentioned support assembly:

[0050] like Figure 1-Figure 4 As shown, the support assembly includes a base plate 2 , a base foot 1 is fixedly connected to the bottom of the base plate 2 , and two top plates 9 are symmetrically fixedly connected to the top of the base plate 2 , and a support rod 6 is fixedly connected between the two top plates 9 .
