Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle sealing strip processing, in particular to a vehicle sealing strip cutting device. BACKGROUND

[0002] The vehicle sealing strip is a key component of the door and window gaps and the vehicle body of the automobile, rail transit and the like, and its main functions include sealing, sound insulation, dust prevention and shock absorption. The material of the vehicle sealing strip is usually an elastic material such as rubber and silicone, which has certain flexibility and resilience. However, due to these characteristics, the sealing strip is prone to irregularities such as curling and bending during production, which affects the cutting process of the sealing strip.

[0003] During the conveying and production of the sealing strip, the surface of the sealing strip may be folded and bent. These folds will have an adverse effect on the dimensional accuracy and flatness of the cutting surface of the sealing strip. Since the sealing strip is directly put into the cutting process in a curled state, there is a lack of effective flattening and straightening mechanism, resulting in large dimensional deviation and uneven cut after cutting, which affects the sealing performance and even causes assembly difficulties. In addition, the sealing strip may be bent upwards due to its own friction or other reasons when cutting, which shortens the measured length and adversely affects the final cutting size. The control accuracy of the existing device cannot meet the production requirements of high-end vehicle sealing strips, mainly because there is a lack of precise monitoring and feedback regulation of the conveying length, flattening treatment and cutting position of the sealing strip, resulting in poor size consistency of the same batch of products, high rejection rate, increased cost of subsequent quality inspection and rework. These problems are superimposed on each other, seriously affecting the production quality of the vehicle sealing strip, weakening the sealing performance and assembly efficiency of the vehicle, and possibly causing water leakage, air leakage, noise increase and other problems during driving due to poor sealing, thereby damaging the use experience and brand reputation of the vehicle. SUMMARY

[0004] The technical problem to be solved by the present application is that the existing technology has the defect that the uneven sealing strip affects the cutting accuracy. Therefore, we propose a vehicle sealing strip cutting device.

[0005] In order to achieve the above purpose, the following technical scheme is adopted in the present application: a vehicle sealing strip cutting device, comprising a base, a top shell fixedly connected to the top of the base, a guide plate rotatably connected to one end of the inside of the top shell through a rotating shaft, two rollers provided on both sides of the inside of the top shell, two extrusion rollers provided in the middle of the top shell, and a conveying roller and a tray.

[0006] A processing mechanism is installed in the inside of the top shell. The processing mechanism drives the two rollers to move inward and close to the two sides of the sealing strip, and then the rollers move forward to flatten and straighten the curled sealing strip.

[0007] The extrusion mechanism is connected to the processing mechanism so that when the roller moves back and forth, it drives the extrusion roller to move down and fit against the top of the sealing strip. Then, it moves linearly with the roller and presses down to seal tightly against the surface of the guide plate, so as to prevent the sealing strip from bunching up when it is cut.

[0008] The feeding mechanism is connected to the processing mechanism so that the extrusion roller deflects downward to push the sealing strip on the surface out to the front end.

[0009] Preferably, the processing mechanism includes:

[0010] The gears are divided into two groups of two, each group consisting of two gears. The gears are installed inside the top shell, and the surfaces of the two gears mesh together to form a toothed chain. A protruding rod is fixedly connected to the top of the toothed chain, and a motor is installed at the bottom of each gear. Two long rods are fixedly connected to both sides of the top of the top shell, and a sliding shell is slidably connected to the two long rods. The sliding shell is slidably connected to the surface of the protruding rod, and a push rod is rotatably connected to the surface of the protruding rod. The push rod is slidably connected to the inside of the sliding shell, and a sleeve is fixedly connected to one end of the push rod. A roller is installed on one side of the sleeve. A moving module is installed on the top of the top shell, and a lifting module is installed on the slide of the moving module. A cutting shear is fixedly connected to the bottom of the lifting module.

[0011] Preferably, the extrusion mechanism includes:

[0012] The inner shell is fixedly connected to the bottom of the top shell. Arc grooves are formed on both sides of the inner shell. A T-shaped rod is fixedly connected to the bottom of the guide plate. A toothed plate is fixedly connected to the top of the outer shell. Toothed columns are rotatably connected to both sides of the top shell via rotating shafts. The top of the toothed plate meshes with the toothed column. A large toothed disc is fixedly connected to one end of the toothed column. L-shaped plates are slidably connected to both sides of the top shell. The outer side of the L-shaped plate meshes with the surface of the large toothed disc. A long groove is formed at the bottom of the L-shaped plate. Both ends of the T-shaped rod are slidably connected to the inner wall of the long groove.

[0013] Preferably, the feeding mechanism includes:

[0014] The grooved plate consists of two plates, each fixedly connected to both sides of the top shell. A sliding plate is slidably connected to the inner wall of the grooved plate. A short rod is fixedly connected to the top of the sliding plate. An extension plate is fixedly connected to one side of the sliding shell. The top of the extension plate is fitted onto the surface of the short rod. The bottoms of the two sliding plates are fixedly connected to both sides of the extrusion roller.

[0015] Preferably, the sleeve has grooves on both sides, the long rod is slidably connected to the inner wall of the groove, and the bottom of the extension plate is slidably connected to the inner wall of the groove.

[0016] Preferably, one end of the guide plate is fixedly connected to an arc plate, which has an arc-shaped structure and is inclined downward.

[0017] Preferably, the two sides of the guide plate are slidably connected to the two sides of the inner wall of the inner shell.

[0018] Preferably, the surface of the top shell is provided with scale lines, and a control terminal is provided on one side of the base.

[0019] The technical effects and advantages of this invention are as follows:

[0020] In this invention, a motor drives a gear and a chain drive to make a circular motion of the protruding rod, which in turn pushes the sleeve along the long rod. This allows the two rollers to first move inward to fit against both sides of the sealing strip, and then move forward in a straight line simultaneously. The rolling friction of the rollers flattens and straightens the curled parts. This bidirectional synchronous flattening action effectively eliminates the curling and bending that occurs during the conveying of the sealing strip, ensuring that the sealing strip is in a straight state before cutting. This significantly improves the cutting size accuracy and cut flatness, and solves the problems of poor sealing performance and difficult assembly caused by insufficient pretreatment in traditional devices.

[0021] In this invention, when the processing mechanism drives the housing to move, the toothed plate drives the toothed column and the large toothed disc to rotate, causing the L-shaped plate to slide up and down. The T-shaped rod pushes the guide plate to deflect to a horizontal state. At the same time, the extrusion roller moves down synchronously with the sliding housing and presses the top of the sealing strip tightly. It follows the roller to move linearly to assist in fixation, forming a double stable structure of "flattening on both sides + pressing on the top". This linkage design achieves adaptive pressing, avoiding the sealing strip from bulging or shifting due to elastic rebound during cutting, ensuring that the measured length is consistent with the actual cutting size. At the same time, flexible extrusion prevents damage to the surface of the sealing strip and is suitable for sealing strips of different hardness materials.

[0022] In this invention, when the processing mechanism resets, the sliding shell drives the extension plate to move, and the short rod pulls the slide plate along the groove plate, causing the extrusion roller to deflect downward. At the same time, the guide plate tilts as the T-shaped rod descends, and the sealing strip slides down the arc plate to the material tray under the guidance of gravity and the extrusion roller, completing automatic collection. This design realizes automatic deflection and unloading of the sealing strip after cutting, avoiding the inefficiency and jamming problems caused by manual cleaning. Combined with the arc-shaped guide structure, it ensures smooth unloading, reduces labor intensity, and improves the continuity of the production line.

[0023] In this invention, the processing mechanism serves as the core transmission hub. Through mechanical linkage, the extrusion mechanism is synchronously driven to achieve pressing, and the unloading mechanism completes deflection. In conjunction with the moving module and the lifting module, the cutting shears are controlled for precise cutting. The entire process requires no additional power source and is completed by a single motor drive. The three mechanisms work together to form an integrated automated process of "flattening - pressing - cutting - unloading", reducing manual intervention, improving the dimensional consistency of products in the same batch, and reducing the defect rate. At the same time, through the precise control of the scale line and the control terminal, it can adapt to the rapid switching of production of multiple specifications of sealing strips, combining the advantages of energy saving and high efficiency.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the invention in a schematic manner, and therefore only show the components relevant to the invention.

[0034] Reference Figure 1 - Figure 8 As shown, the present invention provides a technical solution: a vehicle sealing strip cutting device, including a base 1, a top shell 2 fixedly connected to the top of the base 1, a guide plate 3 rotatably connected to one end of the top shell 2 through a rotating shaft, rollers 4 on both sides inside the top shell 2, two extrusion rollers 5 in the middle of the top shell 2, and also including a conveying roller 6 and a material tray 7.

[0035] The top shell 2 is equipped with a processing mechanism that drives two rollers 4 to move inward toward the sides of the sealing strip. Then the rollers 4 move forward to flatten and straighten the curled sealing strip.

[0036] The extrusion mechanism is connected to the processing mechanism so that when the roller 4 moves back and forth, it drives the extrusion roller 5 to move down and fit against the top of the sealing strip. Then, it moves linearly with the roller 4 and presses down to seal tightly against the surface of the guide plate 3, so as to prevent the sealing strip from bunching up when it is cut.

[0037] The feeding mechanism is connected to the processing mechanism so that the extrusion roller 5 deflects downward to push the sealing strip on the surface out to the front end.

[0038] Reference Figure 1 - Figure 8 As shown in this implementation plan, the processing mechanism includes:

[0039] Gear 8, divided into two groups of two, is installed inside the top shell 2. The surfaces of the two gears 8 are connected to a toothed chain 9. A protruding rod 10 is fixedly connected to the top of the toothed chain 9. A motor 11 is installed at the bottom of the gear 8. Two long rods 12 are fixedly connected to both sides of the top of the top shell 2. The two long rods 12 are slidably connected to a sliding shell 13. The sliding shell 13 is slidably connected to the surface of the protruding rod 10. A push rod 14 is rotatably connected to the surface of the protruding rod 10. The push rod 14 is slidably connected to the inside of the sliding shell 13. A sleeve 15 is fixedly connected to one end of the push rod 14. A roller 4 is installed on one side of the sleeve 15. A moving module 16 is installed on the top of the top shell 2. A lifting module 17 is installed on the slide of the moving module 16. A cutter 18 is fixedly connected to the bottom of the lifting module 17.

[0040] The feeding mechanism includes:

[0041] Two groove plates 27 are fixedly connected to both sides of the top shell 2. A sliding plate 28 is slidably connected to the inner wall of the groove plate 27. A short rod 29 is fixedly connected to the top of the sliding plate 28. An extension plate 30 is fixedly connected to one side of the sliding shell 13. The top of the extension plate 30 fits over the surface of the short rod 29. The bottoms of the two sliding plates 28 are fixedly connected to both sides of the extrusion roller 5. The sealing strip is conveyed forward by the conveying roller 6 into the processing area. The conveyed sealing strip enters the top of the guide plate 3 via the conveying roller 6. Utilizing the tilt angle of the guide plate 3 and the groove design of the inner shell 19, the sealing strip gradually tilts and is positioned on top of the guide plate 3. Subsequently, the processing mechanism is activated, driving the gear 8 to rotate via the motor 11. This causes the toothed chain 9 to rotate, driving the protruding rod 10 to follow the toothed chain 9 in a circular trajectory. After a certain length of sealing strip is conveyed to the top of the guide plate 3, the conveying roller 6 stops running. The rotation of the toothed chain 9 causes the protruding rod 10 to start moving in a semi-circular trajectory along the outside of the gear 8, which in turn causes the protruding rod 10 to move to the other side. During this process, the protruding rod 10 drives the push rod 14 to slide along the inside of the sliding shell 13, and the sliding shell 13 is kept in a fixed position through the sliding connection between the sliding shell 13 and the long rod 12. This makes the sliding shell 13 only move laterally. At the same time, the semi-circular deflection of the push rod 14 and the protruding rod 10 will push the sleeve 15 and the roller 4 closer to the guide plate 3. The sleeve 15 on the other side also moves synchronously, causing the two rollers 4 to move closer to each other.

[0042] During the above process, when the casing 15 moves inward, it pushes the toothed column 23 to rotate clockwise via the toothed plate 22. The rotation of the toothed column 23 drives the large toothed disc 24 to rotate. Due to the transmission ratio of the large toothed disc 24 being greater than that of the toothed column 23, the large toothed disc 24 rotates clockwise and drives the L-shaped plate 25 to move upward. This causes the T-shaped rod 21 to slide inside the long groove 26, pushing the guide plate 3 to deflect upward. During this process, the T-shaped rod 21 slides upward along the arc groove 20, causing the guide plate 3 to gradually rotate to a horizontal state. At this time, a sealing strip has been placed on the surface of the guide plate 3. As the guide plate 3 rotates to be flush with the top casing 2, The sealing strip is moved out from inside the inner shell 19 and placed in the top area of ​​the guide plate 3. As the rollers 4 rise and retract synchronously with the guide plate 3, when the guide plate 3 rotates to a horizontal state, the two rollers 4 also retract synchronously to both sides of the sealing strip. Subsequently, the toothed chain 9 drives the protruding rod 10 to rotate continuously. After the guide plate 3 deflects to a horizontal state and the rollers 4 retract and approach the sealing strip, the protruding rod 10 is on the other side of the toothed chain 9 and moves linearly with the subsequent rotation of the toothed chain 9 until it moves to the gear 8 on the other side. Then it rotates in the opposite direction and returns to the initial position, completing one cutting process.

[0043] During the above process, when the protruding rod 10 moves linearly for the first time, it drives the sliding shell 13 and the sleeve 15 to move synchronously. This causes the sliding shell 13 to move linearly along the long rod 12, keeping the roller 4 always in contact with both sides of the sealing strip. As the two rollers 4 move linearly, they squeeze the sealing strip on the surface of the guide plate 3, straightening and flattening it, so that the sealing strip is placed in the middle area of ​​the guide plate 3 and is in a straight state. When the protruding rod 10 is ready to rotate for the second time, the motor 11 stops running. According to the device size design, the longest sealing strip conveyed to the top of the guide plate 3 cannot exceed the scale line 32, so that the protruding rod 10 has already moved from the sealing strip before the second rotation. The other end of the strip is removed, and it is no longer clamped or limited. At this time, the sealing strip has been straightened and flattened by the processing mechanism and is in a straight state. Then, the moving module 16 and the lifting module 17 start to operate. According to the predetermined cutting size setting, the moving module 16 drives the lifting module 17 to move and adjust the cutting position. The straight length of the sealing strip on the top of the guide plate 3 is measured by the length measuring device inside the top shell 2. Then the lifting module 17 moves to the designated position and pushes the cutting scissors 18 downward to cut. It should be noted that the cutting length of the sealing strip is measured from the front end to the rear end, that is, starting from the scale line 32.

[0044] After the cutting is completed, the lifting module 17 drives the cutting shears 18 to rise and reset. The motor 11 runs again, driving the protruding rod 10 to move in a semi-circle along the gear 8 at the other end to the other side. This process drives the housing 15 to move in the opposite direction. Through the toothed plate 22, the toothed column 23 and the large toothed disc 24 move in the opposite direction, causing the large toothed disc 24 to drive the L-shaped plate 25 to move downward, thereby pushing the T-shaped rod 21 down along the arc groove 20, causing one end of the guide plate 3 to deflect to the initial state. At this time, the sealing strip on the top of the guide plate 3 has been cut by the cutting shears 18. As the guide plate 3 deflects downward, its surface sealing strip slides forward along the surface until it falls into the material tray 7 and is collected, thus completing a cutting process of the sealing strip to the specified size.

[0045] Furthermore, when this device runs once, the protruding rod 10 will follow the toothed chain 9 to make one circular movement. This causes the protruding rod 10 to make two semi-circular movements to complete the lateral movement of the housing 15. This causes the roller 4 to first retract inward and then expand outward to complete the reset operation. The guide plate 3 will also first deflect upward and then deflect downward to reset. This causes the toothed chain 9 to complete one cutting process in one revolution. After the sealing strip is cut, the mechanism is used to reset to the initial state, as shown in the example figure, to prepare for the next cutting process.

[0046] Throughout the process, after the sealing strip is conveyed by the conveyor roller 6, it moves in a straight line along both sides of the sealing strip by the roller 4 before cutting. This process removes any curved or uneven parts on the surface of the sealing strip, ensuring that the sealing strip reaches the optimal straight state before entering the cutting area. The roller 4 is cleverly designed to fit the contour of the sealing strip, effectively removing minor bends without damaging the sealing strip material. This pretreatment step greatly improves the accuracy and efficiency of subsequent cutting, ensuring that the cut sealing strip is sized accurately and meets the high standards of precision and appearance required for vehicle sealing strips.

[0047] Reference Figure 2 - Figure 7 As shown, in this embodiment, the extrusion mechanism includes:

[0048] The inner shell 19 is fixedly connected to the bottom of the top shell 2. Arc grooves 20 are provided on both sides of the inner shell 19. A T-shaped rod 21 is fixedly connected to the bottom of the guide plate 3. A toothed plate 22 is fixedly connected to the top of the outer shell 15. Toothed columns 23 are rotatably connected to both sides of the top shell 2 via rotating shafts. The top of the toothed plate 22 meshes with the toothed column 23. A large toothed disc 24 is fixedly connected to one end of the toothed column 23. L-shaped plates 25 are slidably connected to both sides of the top shell 2. The outer side of the L-shaped plate 25 meshes with the surface of the large toothed disc 24. The L-shaped plate 25 has a long groove 26 at its bottom. Both ends of the T-shaped rod 21 are slidably connected to the inner wall of the long groove 26. When the processing mechanism drives the sliding shell 13 to move linearly along the surface of the long rod 12, the extension plate 30 will move synchronously with the sliding shell 13. The lateral movement of the extension plate 30 will drive the short rod 29 to move linearly in sync. This causes the short rod 29 to drive the slide plate 28 to begin sliding along the inner wall of the groove plate 27. Since the rear end of the groove plate 27 is designed to be inclined upwards, this allows the slide plate 28 to move smoothly. Starting from the initial position, the slide plate 28 tilts downwards until it moves into the straight groove of the groove plate 27, moving in a straight line. When the slide plate 28 descends, the short rod 29 slides downwards along the top of the extension plate 30, causing the bottom of the slide plate 28 to gradually approach the bottom of the top shell 2. This drives the extrusion roller 5 to lower its height, causing the extrusion roller 5 to adhere to the top surface of the sealing strip. Subsequently, the extension plate 30 moves laterally along the sleeve 15, causing the extrusion roller 5 to begin to adhere to the top of the sealing strip and press the sealing strip downwards to adhere tightly to the surface of the guide plate 3. Then, the linearly moving auxiliary roller 4 straightens and flattens the sealing strip to prevent it from bending or folding when placed on the surface of the guide plate 3, ensuring that the sealing strip remains flat and straight. After the slide plate 28 slides along the inner wall of the groove plate 27 to the other end, the circular movement of the toothed chain 9 will cause the extension plate 30 to begin to move in the reverse direction until the slide plate 28 begins to rise along the inclined groove of the initial position, causing the extrusion roller 5 to move away from the top area of ​​the guide plate 3, in order to return to the initial position and prepare for the next extrusion of the sealing strip.

[0049] It is important to note that the extrusion roller 5 is positioned close to the roller 4. When the roller 4 extrudes the sealing strip on both sides, the extrusion roller 5 is located at the rear end of the roller 4. This allows it to flatten the bulges caused by the roller 4's extrusion on both sides of the sealing strip, ensuring the effectiveness of the roller 4 in achieving a smooth seal. The entire cutting device is ingeniously designed, ensuring the stability and accuracy of the sealing strip during the cutting process. Furthermore, the device boasts a high degree of automation, significantly reducing the tediousness of manual operation and improving cutting efficiency. In practical applications, this cutting device demonstrates excellent adaptability and durability, meeting the cutting needs of sealing strips for different vehicle models and providing strong support for the automotive manufacturing industry.

[0050] Reference Figure 7 As shown in this embodiment: Slide grooves 31 are provided on both sides of the housing 15. The long rod 12 is slidably connected to the inner wall of the slide groove 31. The bottom of the extension plate 30 is slidably connected to the inner wall of the slide groove 31. When the sliding shell 13 moves linearly along the long rod 12, the housing 15 is also fitted onto the surface of the long rod 12 through the slide groove 31. When the housing 15 moves laterally, it slides left and right along the surface of the long rod 12, and the bottom of the extension plate 30 slides inside the slide groove 31. Since the housing 15 is only fixedly connected by the push rod 14, the top area of ​​the housing 15 is suspended. The slide groove 31 slides along the long rod 12, so that the force on the housing 15 can also be distributed by the long rod 12, thereby increasing the load-bearing capacity of the housing 15. This makes the operation of the housing 15 more stable.

[0051] Reference Figure 8As shown in this embodiment: one end of the guide plate 3 is fixedly connected to an arc plate 33. The arc plate 33 has an arc-shaped structure and tilts downward. When the sealing strip is cut and begins to tilt downward, the sealing strip begins to slide forward along the surface of the guide plate 3. When the sealing strip slides to the arc plate 33 with the tilt of the guide plate 3, the arc of the arc plate 33 guides the sealing strip, causing the front end of the sealing strip to droop downward through the arc plate 33. This allows the drooping part of the front end of the sealing strip to drag the rear end of the sealing strip downward by its own weight. Afterward, these sealing strips fall into the material tray 7 for collection, or a conveyor belt is installed at the point where the arc plate 33 falls to replace the material tray 7, and these cut sealing strips are then processed. The transfer mechanism allows for more efficient collection and transfer of the cut sealing strips. The arc-shaped guide design of the arc plate 33 ensures smooth sliding of the sealing strips and prevents them from getting stuck at the bottom of the guide plate 3, thus avoiding blockages during device operation. This design also significantly improves the automation of the cutting process, reduces manual intervention, and increases production efficiency. If a conveyor belt replaces the material tray 7, continuous transfer of the cut sealing strips can be further achieved, facilitating subsequent processing or packaging. The entire cutting device design fully considers practicality and efficiency, meeting the actual needs of vehicle sealing strip production.

[0052] Reference Figure 8 As shown in this embodiment: the two sides of the guide plate 3 are slidably connected to the two sides of the inner wall of the inner shell 19. When the guide plate 3 rotates downward, it will be placed inside the inner shell 19. At this time, when the sealing strip is conveyed to the surface of the guide plate 3, it will also be placed inside the inner shell 19 as the guide plate 3 tilts. This makes the sealing strip restricted by the inner shell 19, preventing excessive bending. This ensures that the sealing strip conveyed to the cutting groove on the surface of the guide plate 3 will not deviate from the surface of the guide plate 3. The inner shell 19 limits the two sides of the guide plate 3, ensuring that the sealing strip can be accurately aligned with the material tray 7 for material feeding through the sliding direction of the guide plate 3.

[0053] Reference Figure 1 and Figure 3As shown in this embodiment: the surface of the top shell 2 is provided with scale lines 32, and a control terminal 34 is provided on one side of the base 1. The scale lines 32 serve as the proximity points for the conveying length of the sealing strip. This allows the conveying roller 6 to accurately position the sealing strip according to its actual length when conveying it to the surface of the guide plate 3, ensuring that the length of the sealing strip is consistent each time it is conveyed, thus improving the cutting accuracy. At the same time, the design of the scale lines 32 also takes into account the stability of the sealing strip during the conveying process. Through a reasonable structural layout, the sealing strip is less likely to deviate or slide during the conveying process, further ensuring the cutting quality. In addition, the setting of the control terminal 34 facilitates the overall adjustment and control of the cutting device, allowing operators to flexibly adjust the cutting parameters according to actual needs, thus meeting the production requirements of sealing strips of different specifications.
