[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0022] Example

[0023] Depend on Figure 1-4 Provided is a cutting device for producing rubber sealing rings, comprising a conveyor belt mechanism 1;

[0024] Two sets of lifting components 2 are installed on the side of the conveyor belt mechanism 1; the two sets of lifting components 2 are arranged opposite to each other and pressing components 3 are slidably installed on the two sets of lifting components 2;

[0025] The pressing assembly 3 includes a connecting seat 31 slidably arranged on the lifting assembly 2, and connecting blocks 32 are respectively connected to the two sides of the connecting seat 31. Bolt shafts 33 are rotatably connected to the two connecting blocks 32 and are connected to a lower pressing arm 35 through the bolt shaft 33. A plurality of groups of compression springs 36 are arranged at the bottom of the lower pressing arm 35 along its transverse direction, and a pressure plate 37 is arranged at the bottom of the plurality of compression springs 36.

[0026] In this embodiment, in actual use, through the mutual movement and coordination of multiple components in the set lifting assembly 2, the set lifting assembly 2 can drive the pressing assembly 3 to move up and down. At this time, the user controls the lower pressing arm 35 in the set pressing assembly 3 to move downward until the compression spring 36 is compressed, so that the four pressing plates 37 on the two groups of pressing assemblies 3 can stably press and position the rubber sealing ring raw material. At this time, the user can drive the cutting tool to cut the rubber sealing ring. Compared with the rubber ring cutting method in the cited document, by adding the lifting assembly 2 and the pressing assembly 3 on the basis of the cited document, the raw material of the rubber sealing ring can be better positioned to facilitate cutting by the cutting tool, which is more practical as a whole.

[0027] Specifically, refer to Figure 3-4 The pressing plate 37 is a rubber sheet, and the bottom of the pressing plate 37 is engraved with a mesh anti-skid pattern.

[0028] In this embodiment, when the user places the raw material of the rubber sealing ring on the conveyor belt mechanism 1 and drives the conveyor belt mechanism 1 to transport the raw material, the user can then drive the lifting component 2 to lift and adjust the pressing component 3 until the set pressing plate 37 is displaced and lowered. At this time, the bottom of the pressing plate 37 is in contact with the surface of the rubber sealing ring raw material. The mesh anti-slip texture on the pressing plate 37 can increase the friction between the rubber sealing ring raw material and the raw material to maintain a fixed position during the molding process, which helps to ensure that the molded rubber sealing ring has a consistent size and shape, and at the same time cooperates with the deformation and tightness of the compression spring 36 to further improve the downward pressure effect on the rubber ring raw material.

[0029] Specifically, refer to Figure 2-4 The top end of the bolt shaft 33 passes through the connecting block 32 and is connected to a handle 34 , and a cross-shaped ear plate is arranged outside the handle 34 .

[0030] In this embodiment, when the user rotates the handle 34, the bolt shaft 33 will rotate accordingly, and gradually break away from the limit of the connecting block 32. At this time, the connecting block 32 can rotate in the connecting seat 31. The user can adjust the angle between the connecting block 32 and the connecting seat 31, as shown in the embodiment. Figure 3 As shown, the pressing arm 35 connected to the side of the connecting block 32 can rotate accordingly. When the angle between the pressing arm 35 and the connecting seat 31 changes and gradually decreases, the pressing arm 35 set at this time can press down and fix the rubber ring material of a small area. Similarly, when the angle spacing between the two pressing arms 35 in a group of pressing components 3 is enlarged, the pressing arm 35 set can press down and fix the rubber ring material of a larger area, thereby improving the overall use range of the material fixation.

[0031] Specifically, refer to Figure 1-3 The lifting assembly 2 includes a screw box 21 arranged on the side of the conveyor belt mechanism 1. A slide groove is opened on the front of the screw box 21. A screw 23 is rotatably arranged in the screw box 21. A slider seat 25 is slidably engaged with the outside of the screw 23. One side of the slider seat 25 passes through the slide groove and is connected to the connecting seat 31.

[0032] In this embodiment, when the reciprocating motor 22 in the lifting assembly 2 is connected to the power supply and driven, the screw 23 provided at this time can rotate synchronously. When the screw 23 is rotating, it is limited by the slide groove of the screw box 21, so that the slider seat 25 engaged with the outside of the screw 23 can drive the pressing assembly 3 to move as a whole.

[0033] Specifically, refer to Figure 1-3 A bearing seat 24 is also provided in the lead screw box 21 , and the bearing seat 24 is rotatably connected to the top end of the lead screw 23 .

[0034] In this embodiment, the bearing seat 24 can cooperate with the rotation of the lead screw 23 to make the lead screw 23 rotate more smoothly, while reducing the vibration amplitude of the lead screw 23 and improving the displacement stability of the slider seat 25.

[0035] Specifically, refer to Figure 1-3 A reciprocating motor 22 is assembled in the lead screw box 21 , a power slot is opened at the bottom of the lead screw box 21 , and the output end of the lead screw box 21 is rotatably connected to the bottom end of the lead screw 23 .

[0036] In this embodiment, when the reciprocating motor 22 in the lifting assembly 2 is connected to the power supply and driven, the screw 23 provided at this time can rotate synchronously, and the power slot opened at the bottom of the screw box 21 can be used to connect the power cord to the screw box 21.

[0037] The utility model of cutting device for rubber sealing ring production:

[0038] Step 1: In actual use, when the user needs to cut the rubber sealing ring, the user drives the conveyor belt mechanism 1 to transport the rubber sealing ring raw material. When the rubber sealing ring raw material is transported to the bottom of the cutting device, the user drives the two sets of lifting components 2 to move. At this time, the set lifting components 2 can drive the pressing component 3 to move the vertical height, thereby fixing the rubber sealing ring through the pressing component 3;

[0039] Step 2: When the reciprocating motor 22 in the lifting assembly 2 is connected to the power supply and driven, the screw 23 set at this time can rotate synchronously. When the screw 23 is rotating, it is limited by the slide groove of the screw box 21, so that the slider seat 25 engaged with the outside of the screw 23 can drive the pressing assembly 3 to move as a whole until the set pressure plate 37 contacts the rubber sealing ring material. At this time, the user controls the set lower pressure arm 35 to continue to move downward until the compression spring 36 is compressed, so that the four pressure plates 37 on the two groups of pressing assemblies 3 can stably press and position the rubber sealing ring material. At this time, the user can drive the cutting tool to cut the rubber sealing ring.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
