Technical Field

[0001] This utility model relates to the field of sealing strip processing technology, and in particular to a punching device for automotive sealing strips. Background Technology

[0002] Sealing strips are functional products used to fill gaps and prevent media leakage or intrusion. They mainly serve functions such as shock absorption, waterproofing, sound insulation, heat insulation, dust prevention, and fixation. They fill the gaps in the joints through elastic deformation to ensure sealing. They are widely used in industries such as automobiles, doors and windows, cabinets, and containers. Sealing strips are made of various materials, including rubber, plastics, metals, and composite materials. Choosing the right material according to different application scenarios is crucial.

[0003] However, in the existing technology, existing automotive sealing strips are usually cut according to needs. During the cutting process, a fixed-length conveying method is usually used to cut sealing strips of the same length. The existing cutting conveying structure usually has the problem that the fixed length of the conveying is fixed and cannot be adjusted according to the needs. This results in a relatively simple conveying length. When it is necessary to cut sealing strips of different lengths, the equipment needs to be changed, which is inconvenient for people to use.

[0008] In a preferred embodiment, a slider is fixedly installed on the outer side of each of the second rotating rods, and a plurality of vertical sliding grooves are provided on one side of the second turntable. An arc-shaped sliding groove is formed on one side of each of the vertical sliding grooves, and a limiting groove is formed on one side of each of the arc-shaped sliding grooves. The vertical sliding grooves, arc-shaped sliding grooves, and limiting grooves are all adapted to the sliders.

[0009] In a preferred embodiment, a motor is fixedly installed on one side of the L-shaped plate, and the output end of the motor passes through one side of the L-shaped plate and is fixedly connected to the second turntable.

[0010] In a preferred embodiment, a cutting groove is provided on the top of the conveyor frame, the cutting groove is located directly below the cutting blade, a limit roller is rotatably installed on the inner side of the conveyor frame, and a sealing strip body is sleeved on the outer side of the take-up roller.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. This utility model uses the second rotating rod to drive the slider to slide from the inside of the limiting groove into the inside of the arc-shaped slide groove. Then, the second rotating rod is rotated to drive the slider to slide inside the arc-shaped slide groove. The slider is slid to one side of the vertical slide groove. Then, through the elastic action of the first return spring, the second rotating rod and the slider on its outer side are driven to slide out from the circular slide groove and the vertical slide groove respectively, so that the second rotating rod can contact the first rotating rod, thereby realizing the intermittent conveying and cutting of sealing strip bodies of different lengths, effectively improving the practicality of the device.

Detailed Implementation

[0022] 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.

[0023] Example 1

[0024] like Figure 1-4As shown, this utility model provides a technical solution: a punching device for automotive sealing strips, comprising: a support frame 11 and a conveyor frame 15. A hydraulic rod 12 is fixedly installed on the top of the support frame 11, and a pressure plate 13 is fixedly installed through the bottom end of the hydraulic rod 12 through the support frame 11. A cutting blade 14 is fixedly installed at the bottom of the pressure plate 13. A conveying structure 2 is provided on one side of the conveyor frame 15. The conveying structure 2 includes two fixed seats 21, and a take-up roller 22 is rotatably installed between the two fixed seats 21. Two baffles 23 are fixedly installed on the outer side of the take-up roller 22. One end of the take-up roller 22 passes through one of the fixed seats 21 and is fixedly installed on a first turntable 24. A plurality of first rotating rods 25 are fixedly installed on the outer side of the first turntable 24. An L-shaped plate 26 is fixedly installed on one side of one of the fixed seats 21. A second turntable 27 is rotatably installed on one side of the L-shaped plate 26. A plurality of second rotating rods 28 are provided on one side of the second turntable 27. The plurality of first rotating rods 25 and the plurality of second rotating rods 28 are respectively staggered. The bottom of the pressure plate 13 is provided with a limit structure 3. Several circular grooves are formed on one side of the second turntable 27. Several second rotating rods 28 are respectively disposed inside the circular grooves and slide in contact with the second turntable 27. A first-order return spring 29 is fixedly installed inside each of the circular grooves of the second turntable 27. A rotating seat 210 is fixedly installed at one end of the first-order return spring 29. The rotating seat 210 is rotatably connected to the second rotating rod 28. Sliders are fixedly installed on the outer sides of each of the second rotating rods 28. Block 212, a number of vertical grooves 213 are provided on one side of the second turntable 27, an arc-shaped groove 214 is formed on one side of each of the vertical grooves 213, and a limiting groove 215 is formed on one side of each of the arc-shaped grooves 214. The vertical grooves 213, arc-shaped grooves 214 and limiting grooves 215 are all adapted to the slider 212. A motor 216 is fixedly installed on one side of the L-shaped plate 26. The output end of the motor 216 passes through one side of the L-shaped plate 26 and is fixedly connected to the second turntable 27.

[0025] In this embodiment, the plurality of first rotating rods 25 and the plurality of second rotating rods 28 are arranged in an alternating pattern. When the second turntable 27 rotates, the second rotating rods 28 contact the first rotating rods 25, thereby driving the first turntable 24 to rotate, which in turn drives the take-up roller 22 to rotate and convey and release the outer sealing strip body 18. The circular groove on the front side of the second turntable 27 reduces the length of the second rotating rod 28 that protrudes when it slides in, thus allowing the second turntable 27 to slide into the circular groove when rotating. The second turntable 27 inside the circular groove will not be able to contact the first rotating rod 25 to drive the first turntable 24 to rotate. Through the set first return spring 29, the second rotating rod 28 can be slid into the circular groove. When the second rotating rod 28 is rotated to slide the slider 212 through the vertical groove 213 and the arc-shaped groove 214 into the limiting groove 215, the elastic action of the first return spring 29 will push the slider 212 into the limiting groove 215, thereby limiting and fixing the second rotating rod 28 and preventing the second rotating rod 28 from popping out.

[0026] Example 2

[0027] like Figure 1 and 5 As shown, a cutting groove 16 is provided on the top of the conveyor frame 15, and the cutting groove 16 is located directly below the cutting blade 14. A limiting roller 17 is rotatably installed on the inner side of the conveyor frame 15, and a sealing strip body 18 is sleeved on the outer side of the take-up roller 22. The limiting structure 3 includes two second return springs 31, both of which are fixedly installed on the bottom of the pressure plate 13. A limiting plate 32 is fixedly installed at the bottom end of both second return springs 31, and a guide post 33 is fixedly installed on the top of both limiting plates 32. Both guide posts 33 penetrate the pressure plate 13 and slide in contact with the pressure plate 13.

[0028] In this embodiment, the cutting groove 16 effectively prevents the cutting blade 14 from directly contacting the conveyor frame 15 during cutting, thus avoiding significant wear on the blade tip and reduced cutting effect. The limiting roller 17 limits the conveying of the sealing strip body 18, preventing it from warping and ensuring stable cutting. The guide column 33 effectively limits the limiting plate 32, ensuring that the two limiting plates 32 press down with the pressure plate 13 to limit and fix the sides of the sealing strip body 18, preventing warping. During return, the limiting plate 32 is kept in a vertical position, preventing movement and tilting.

[0029] Working principle:

[0030] like Figure 1-5As shown, during use, one end of the sealing strip body 18 is passed between the conveyor frame 15 and the limiting roller 17, and then the motor 216 is started. The specific model of the motor 216 is not described, but is based on the compatible equipment. The motor 216 will drive the second turntable 27 to rotate, thereby driving several second rotating rods 28 to rotate. The parts of several second rotating rods 28 that slide out will contact several first rotating rods 25, thereby driving the first turntable 24 to rotate intermittently, thereby driving the sealing strip body 18 on the outside of the take-up roller 22 to be conveyed intermittently. When the conveying stops, the hydraulic rod 12 is started to drive the pressure plate 13 to move downward, thereby driving the cutting blade 14 to cut the sealing strip body 18.

[0031] During the cutting process, the pressure plate 13 drives the two limiting plates 32 to move downward through the two second return springs 31, thereby pressing and fixing the two limiting plates 32 on both sides of the sealing strip body 18. Then, the pressure plate 13 continues to press down to drive the cutting blade 14 to cut. The two second return springs 31 will also be compressed and deformed to improve the limiting effect on the sealing strip body 18, thereby ensuring that the two sides of the sealing strip body 18 at the cutting position will not curl up and affect the cutting during the cutting process, effectively improving the use effect of the device.

[0032] When it is necessary to cut sealing strip bodies 18 of different lengths, press the corresponding number of second rotating rods 28 according to the length requirements. The second rotating rods 28 will drive the slider 212 to slide from the inside of the limiting groove 215 into the inside of the arc-shaped slide groove 214. Then rotate the second rotating rod 28 to drive the slider 212 to slide inside the arc-shaped slide groove 214, and slide the slider 212 to one side of the vertical slide groove 213. Then release the second rotating rod 28. Through the elastic action of the first return spring 29, the rotating seat 210 will drive the second rotating rod 28 and the slider 212 on its outer side to slide out from the circular slide groove and the vertical slide groove 213 respectively, so that the second rotating rod 28 can contact the first rotating rod 25 to realize the intermittent conveying and cutting of sealing strip bodies 18 of different lengths, which effectively improves the practicality of the device.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
