[0002] Seals are materials or parts that prevent fluids or solid particles from leaking between adjacent mating surfaces and prevent external impurities such as dust and moisture from invading the internal components of machinery and equipment. According to their functions, they are divided into shaft seals, hole seals, dustproof seals, guide rings, fixed seals, and rotary seals. According to their materials, they are nitrile rubber, EPDM rubber, fluororubber, silicone, fluorosilicone rubber, nylon, polyurethane, engineering plastics, etc. During the production process of mechanical seals, the semi-finished products need to be cut into the required length and then processed into finished products.

[0003] However, in the existing production of mechanical seals, when cutting, it is necessary to manually move the semi-finished sealing strip to the bottom of the cutting device, and then cut it into the required length and then connect it to form a sealing ring. The work efficiency is low, and the length is not easy to control, and slight deviations are prone to occur. Therefore, we propose a cutting device for the production of mechanical seals to solve the above problems. Utility Model Content

[0023] Example

[0024] Please refer to Figure 1-4 As shown, the utility model provides a technical solution: a cutting device for producing mechanical seals;

[0025] A cutter 4 is fixedly installed at the front end of the workbench 1, a cutting knife 5 is fixedly installed at the inner end of the cutter 4, a clamping groove 6 is opened at the inner end of the workbench 1, a collection basket 7 is clamped and installed at the inner end of the clamping groove 6, a moving groove 10 is opened at the inner end of the workbench 1, and a mounting plate 9 is clamped and installed at the inner end of the moving groove 10;

[0026] The inner end of the feeding belt 2 is meshedly connected with a driving wheel 8, the rear end of the driving wheel 8 is rotatably mounted with a mounting plate 9, the outer end of the mounting plate 9 is fixedly mounted with an electric telescopic rod 11, and the feeding belt 2 is divided into two groups, the upper and lower groups, which are arranged at the front side of the workbench 1, so as to realize automatic equal feeding, accurate and fast cutting, and improve production efficiency;

[0027] The cutting seat 3 is fixedly mounted at the front end of the workbench 1, and a limiter 12 is mounted on the inner end of the cutting seat 3, and a cutting groove 14 is provided at the inner end of the cutting seat 3. The limiters 12 are installed at the inner end of the cutting seat 3 in two groups, and a through groove 13 is provided at the inner end of the limiters 12. The through groove 13 is arranged on the left side of the two groups of feeding belts 2. The cutting knife 5 is arranged on the upper side of the cutting groove 14, which is convenient for replacing the limiter 12 and is suitable for cutting seals of different models and shapes.

[0028] Specific working principle:

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when the cutting device for producing mechanical seals is used, the semi-finished seal to be cut is passed through the gap between the feeding belt 2 and the feeding belt 2, and through the through slot 13, and then the electric telescopic rod 11 is started, and the electric telescopic rod 11 drives the mounting plate 9 to move at the inner end of the moving slot 10, thereby driving the two groups of feeding belts 2 to move toward each other, clamping the seal to a suitable tightness, and starting the transmission wheel 8. The driving device of the transmission wheel 8 drives the transmission wheel 8 to rotate at a uniform speed. When the transmission wheel 8 rotates, the transmission wheel 8 drives the feeding belt 2 to move, and the two groups of feeding belts 2 rotate in the opposite direction, pushing the seal to the left. After being pushed to the set length, the cutter 4 drives the cutting knife 5 to move downward, and the cutting knife 5 enters the inner end of the cutting slot 14 to cut the seal passing through the through slot 13, and then the feeding belt 2 continues to feed, and pushes the cut section into the inside of the collecting basket 7;

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the limit member 12 is snap-fitted and installed inside the cutting seat 3 and reinforced by bolts. When it is necessary to cut seals of different types, the limit member 12 is removed from the inner end of the cutting seat 3 and replaced with different through grooves 13. At the same time, the width between the feeding belts 2 and the feeding belts 2 can be adjusted by the electric telescopic rod 11, which has high flexibility in use. The above completes a series of operations of the cutting device for the production of mechanical seals. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
