[0002] Automotive sealing strips are important automotive components, mainly made of materials such as EPDM rubber. They are used in car doors, windows, body, sunroof, and engine compartment, and have functions such as waterproofing, sealing, sound insulation, dustproofing, shock absorption, and heat insulation. Their structure includes metal clamps and tongue-shaped buckles for easy installation and fixation, and they can withstand temperatures ranging from -40℃ to 120℃.

[0003] The patent CN219445189U discloses a cutting device for automotive sealing strips. This patent discloses a convenient positioning technical solution, which solves the problem that existing rubber strip cutting devices do not have the ability to position the rubber strip. If the rubber strip deviates during cutting, it will easily lead to uneven blades and affect the quality of the rubber strip.

However, it is not convenient to restrict rubber strips of different sizes, which reduces the effectiveness of use and cutting. Therefore, a cutting device for automotive sealing rubber strips is proposed to solve the above problems. Utility Model Content

[0028] The limiting assembly includes two locking plates 17, which are placed inside two clearance slots 6 respectively. The top surfaces of the two fixing plates 7 are provided with mounting slots 15. The inside of the two mounting slots 15 are fixedly installed with first electric push rods 16. The output ends of the two first electric push rods 16 pass through the fixing plates 7 and extend to the locking plates 17. The output ends of the first electric push rods 16 are fixedly connected to the locking plates 17. The bottom surfaces of the two locking plates 17 are provided with locking grooves 18.

[0029] The two fixing plates 7 each have a first through hole inside. The output end of the first electric push rod 16 passes through the first through hole and is fitted with it with a clearance. The slot 18 is an arc-shaped slot.

[0030] Specifically, the first electric push rod 16 is activated, and the output end of the first electric push rod 16 drives the clamping plate 17 to move downward, so that there is a gap between the clamping plate 17 and the adhesive strip, thereby restricting the adhesive strip. When it is in a suitable position, the clamping plate 17 continues to move downward, so that the adhesive strip and the clamping groove 18 fit together and fix the adhesive strip.

[0031] Please see Figures 1 to 4 In this embodiment, the mounting plate 8 is provided with a cutting assembly for cutting the adhesive strip. The cutting assembly includes a second electric push rod 11, which is fixedly installed on the top surface of the mounting plate 8. The output end of the second electric push rod 11 passes through the mounting plate 8 and extends to its bottom. The output end of the second electric push rod 11 is fixedly connected to a linkage plate 14. A cutter 13 is fixedly connected to the bottom surface of the linkage plate 14. A cutting groove 19 adapted to the cutter 13 is opened on the top surface of the placement plate 1. Two support holes 12 are opened on the top surface of the mounting plate 8. Two support rods 9 are fixedly connected to the top surface of the linkage plate 14, with one end passing through the support hole 12 and extending to the top of the mounting plate 8. Limiting plates 10 are fixedly connected to the top surfaces of the two support rods 9.

[0032] The cutting groove 19 and the cutter 13 are both located between the two fixed plates 7. The support rod 9 and the support hole 12 are fitted with a clearance. The top surface of the mounting plate 8 is provided with a second through hole. The output end of the second electric push rod 11 passes through the second through hole and is fitted with it with a clearance.

[0033] Specifically, the second electric push rod 11 is activated, and the output end of the second electric push rod 11 drives the cutter 13 to move downward through the linkage plate 14. The rubber strip is cut by the cooperation between the cutter 13 and the cutting groove 19. The linkage plate 14 is supported by the gap cooperation between the support rod 9 and the support hole 12, thereby improving the stability of the linkage plate 14.

[0034] It should be noted that the first electric actuator 16 and the second electric actuator 11 are both conventional devices known in the prior art, and their specific structures and working principles will not be described in detail here. This application can ensure that the output ends of the two first electric actuators 16 extend and retract simultaneously by using a synchronization controller or other synchronization device, thereby achieving synchronous operation. These synchronization devices are common and mature in the field of electric control, so they will not be described in detail in the specific embodiments.

[0035] Please see Figures 1 to 4 In this embodiment, the placement plate 1 is provided with a conveying assembly for conveying the adhesive strip. The conveying assembly includes two drive motors 20, both of which are fixedly installed on the back of the placement plate 1. The top surface of the placement plate 1 has two placement slots 2. The interior of each of the two placement slots 2 is rotatably connected to two drive rods 3 via bearings. Connecting rollers 4 are fixedly fitted on the outer peripheral walls of the four drive rods 3. A conveyor belt 5 is fitted between the outer peripheral walls of two adjacent connecting rollers 4. The two drive rods 3 in the middle pass through the placement slots 2 and extend to the back of the placement plate 1. The output shafts of the two drive motors 20 are fixedly connected to the two middle drive rods 3 respectively.

[0036] Among them, the two drive rods 3 in the middle are rotatably connected to the placement plate 1 through bearings, the two fixed plates 7 are located between the two placement slots 2, and the top surface of the conveyor belt 5 and the top surface of the placement plate 1 are on the same horizontal line.

[0037] Specifically, the drive motor 20 is started, and the output shaft of the drive motor 20 drives the intermediate drive rod 3 to rotate, causing the connecting roller 4 to rotate, which in turn drives the conveyor belt 5 to move. The conveyor belt 5 drives the rubber strip to move and transport it.

[0038] It should be noted that this application can achieve synchronous operation by employing a synchronization controller or other synchronization device to ensure that the output bearings of the two drive motors 20 rotate simultaneously. These synchronization devices are common and mature in the field of electric control, and therefore will not be described in detail in specific embodiments.

[0039] The working principle of the above embodiments is as follows:

[0040] Start the drive motor 20. The output shaft of the drive motor 20 drives the intermediate drive rod 3 to rotate, causing the connecting roller 4 to rotate, which in turn drives the conveyor belt 5 to move. The conveyor belt 5 drives the rubber strip to move and convey it. Start the first electric push rod 16. The output end of the first electric push rod 16 drives the clamping plate 17 to move downward, creating a gap between the clamping plate 17 and the rubber strip, thereby restricting the rubber strip. When it is in a suitable position, the clamping plate 17 continues to move downward, so that the rubber strip and the clamping groove 18 fit together and fix the rubber strip. Start the second electric push rod 11. The output end of the second electric push rod 11 drives the cutter 13 to move downward through the linkage plate 14. Through the cooperation between the cutter 13 and the cutting groove 19, the rubber strip is cut off. Through the gap cooperation between the support rod 9 and the support hole 12, the linkage plate 14 is supported, improving the stability of the linkage plate 14.

[0041] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
