[0002] Silicone gaskets are a type of sealing ring. Silicone is a rubber material. Due to its special properties, wide temperature range, and excellent chemical properties, it is known as a special rubber along with fluororubber. Silicone is widely used in the manufacture of various seals.
[0003] After the silicone gaskets are manufactured, they need to be trimmed to remove excess waste. Currently, this is mostly done manually with a trimming knife, which is inefficient and cannot guarantee that the burrs on each silicone gasket can be repaired well. Therefore, we propose a silicone gasket trimming device. Utility Model Content

[0014] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figs. 1-3 This utility model provides a technical solution: a silicone gasket trimming device, including a fixed platform 1, a first turntable 2 rotatably mounted on the upper middle part of the fixed platform 1, the first turntable 2 being driven to rotate by a first motor 13, a plurality of second turntables 3 arrayed near the outer diameter of the first turntable 2, the second turntables 3 being rotatably connected to the first turntable 2 by a rotating shaft, the second turntables 3 being driven to rotate by a rotating mechanism 4, a threaded post 5 provided on the upper end of the second turntable 3, a threaded sleeve 6 sleeved on the outside of the threaded post 5, the threaded sleeve 6 being threadedly connected to the threaded post 5, a fixed plate 7 provided on one side of the fixed platform 1, and a trimming knife 8 movably mounted on the fixed plate 7.
[0016] The second turntable 3 and the threaded sleeve 6 are used to install silicone gaskets. In use, the silicone gasket is fitted onto the threaded sleeve 6, with the bottom of the silicone gasket positioned above the second turntable 3. The outer diameter of the threaded sleeve 6 tightens the inner diameter of the silicone gasket, preventing it from easily falling off. The threaded sleeve 6 is connected to the threaded post 5 via threads, facilitating disassembly and replacement. Therefore, a matching threaded sleeve 6 can be used depending on the size of the silicone gasket, making it suitable for various specifications of silicone gaskets. After the silicone gasket is installed, the first motor 13 drives the first turntable 2 to rotate at a certain angle, rotating the silicone gasket to the position of the trimming knife 8. The rotating mechanism 4 drives the second turntable 3 to rotate, causing the silicone gasket to rotate. The trimming knife 8 then trims the rotating silicone gasket. By intermittently rotating the first turntable 2 driven by the first motor 13, the trimmed silicone gasket on the second turntable 3 can be removed, and a new silicone gasket requiring trimming can be placed in. The trimming knife 8 can trim the silicone gaskets installed on the second turntable 3 sequentially.
[0017] The rotating mechanism 4 includes a second motor 41 fixedly installed at the bottom of the fixed platform 1. The output end of the second motor 41 is provided with a first friction wheel 42. The second turntable 3 is fixedly connected to a second friction wheel 43 through a rotating shaft. The second friction wheel 43 is located below the first turntable 2. The second friction wheel 43 is tangent to the first friction wheel 42. Both the outer diameter of the first friction wheel 42 and the second friction wheel 43 are fitted with rubber rings 44.
[0018] The first friction wheel 42 drives the second friction wheel 43 to rotate through friction. Rubber rings 44 are installed on the outer diameters of the first friction wheel 42 and the second friction wheel 43 to ensure close contact between them. When the second motor 41 drives the first friction wheel 42 to rotate, the first friction wheel 42 can drive the second friction wheel 43 to rotate, thus causing the second turntable 3 to rotate.
[0019] The distance between the trimming knife 8 and the second turntable 3 is adjusted by the adjustment mechanism 9. The adjustment mechanism 9 includes two guide posts 91 located inside the fixed plate 7. A knife holder 92 is slidably connected to the guide posts 91. The trimming knife 8 is fixedly installed on the knife holder 92. The fixed plate 7 is connected to a threaded rod 93 by a thread. One end of the threaded rod 93 is provided with a knob 94, which is located outside the fixed plate 7. The other end of the threaded rod 93 is movably connected to the knife holder 92.
[0020] Depending on the size of the silicone gasket, the trimming knife 8 can be adjusted by the adjustment mechanism 9 so that the trimming knife 8 can contact the silicone gasket to remove waste. By rotating the knob 94, the threaded rod 93 moves on the fixed plate 7, so that the knife holder 92 can move closer to or further away from the second turntable 3. Therefore, the distance between the trimming knife 8 mounted on the knife holder 92 and the second turntable 3 changes, thereby realizing the distance adjustment.
[0021] The upper end of the fixed plate 7 is provided with a horizontal plate 10, and a blower pipe 11 for cleaning waste is installed on the horizontal plate 10. The air outlet of the blower pipe 11 faces the position of the trimming knife 8. A waste box 12 is provided below the trimming knife 8, and an opening is provided at the upper end of the waste box 12.
[0022] During the trimming of the silicone gasket, waste material is generated. The trimming knife 8 is continuously blown by the air blower 11, and the waste material removed by the trimming knife 8 is blown away by the air blower 11 and falls into the waste box 12, which can collect the waste material.
[0023] The working principle and usage process of this utility model are as follows: In use, the silicone gasket is fitted onto the threaded sleeve 6, so that the bottom of the silicone gasket is located at the upper end of the second turntable 3. The outer diameter of the threaded sleeve 6 can tighten the inner diameter of the silicone gasket, so that the silicone gasket will not easily fall off. After the silicone gasket is installed, the first motor 13 drives the first turntable 2 to rotate at a certain angle, so that the silicone gasket is rotated to the position of the trimming knife 8. The second turntable 3 is driven to rotate by the rotating mechanism 4, so that the silicone gasket rotates. The trimming knife 8 can then trim the rotating silicone gasket. The first motor 13 drives the first turntable 2 to rotate intermittently, so that the trimmed silicone gasket on the second turntable 3 can be removed, and a new silicone gasket that needs to be trimmed can be put in again. The trimming knife 8 can trim the silicone gaskets installed on the second turntable 3 in turn.
[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
