Technical Field

[0001] This utility model relates to the field of automotive wiper blade technology, specifically an automotive wiper blade cutting machine. Background Technology

[0002] A wiper blade cutting machine is a device specifically designed for cutting wiper blades. It typically has a mechanical transmission device, such as a motor driving a belt or gear transmission, to partially automate the conveying and cutting of the blades. Manual feeding and control of the cutting start are still required.

[0003] In the comparative case, patent publication number CN222472588U discloses an automatic adhesive strip cutting machine, including a base.

A photoelectric encoder is installed on one side of the base, and the measuring end of the photoelectric encoder is fixedly connected to the drive wheel. This utility model relates to the field of adhesive strip cutting machine technology and solves the problem that in the prior art, automatic adhesive strip cutting machines require manual measurement of the adhesive strip length, which easily leads to errors in the cut length. Furthermore, the operation process is cumbersome and time-consuming, affecting the efficiency of adhesive strip cutting.

[0004] However, in implementing the relevant technology, the above-mentioned automatic rubber strip cutting machine was found to have the following problems. The comparative case uses a photoelectric encoder to measure the number of rotations of the drive wheel of the rubber strip cutting machine and automatically calculates the transmission distance of the rubber strip material, enabling the rubber strip cutting machine to perform automatic cutting, reducing the error caused by manual measurement, and making the operation simpler and reducing the time required for measurement. This can improve the production efficiency of rubber strip cutting. The existing rubber strip cutting machine requires manual feeding and cutting operations, which does not protect the operator's hands and is prone to safety accidents, reducing the safety of using the rubber strip cutting machine.

[0005] Therefore, the design of the rubber strip cutting machine needs to be modified to effectively prevent the safety accidents that may occur due to the lack of protection for the operator's hands during manual feeding and cutting operations. Utility Model Content

[0018] 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.

[0019] like Figures 1 to 6 As shown, the present invention provides a car windshield wiper rubber strip cutting machine, comprising: The bracket 1 has a worktable 2 fixedly connected to its top. A drive motor 3 is installed on the right side of the bottom of the worktable 2. Sliding mechanisms 4 are fixedly connected to the front and back ends of the top of the worktable 2. The sliding mechanism 4 includes a rectangular plate 41, a slider 42, and a grooved plate 43. The front and back ends of the top of the worktable 2 are fixedly connected to the rectangular plate 41. The slider 42 is slidably connected to the left side of the top of the rectangular plate 41. The top of the slider 42 is fixedly connected to the grooved plate 43. The top of the grooved plate 43 is inserted with a fixing mechanism 5.

[0020] refer to Figure 3 The fixing mechanism 5 includes an iron block 51, a cover plate 52 and a magnet block 53. An iron block 51 is inserted into the top of the groove plate 43, and a cover plate 52 is fixedly connected to the top of the iron block 51. A magnet block 53 is provided at the front and back ends of the inner cavity of the groove plate 43 and at the position corresponding to the iron block 51. An auxiliary mechanism 6 is fixedly connected to the right side of the inner wall of the rectangular plate 41.

[0021] As a technical optimization of this utility model, by setting the fixing mechanism 5, the iron block 51 can be inserted downward into the groove plate 43 by holding the cover plate 52. When the iron block 51 is inserted into the groove plate 43 and is magnetically fixed with the magnet block 53, the groove plate 43 can fix and cover the adhesive strip, thus avoiding the phenomenon of the adhesive strip detaching inside the groove plate 43.

[0022] refer to Figure 3 The auxiliary mechanism 6 includes a telescopic rod 61, a tension spring 62, and a handle 63. The telescopic rod 61 is fixedly connected to the right side of the inner wall of the rectangular plate 41. The left side of the telescopic rod 61 is fixedly connected to the right side of the slider 42. The tension spring 62 is sleeved on the surface of the telescopic rod 61. The left and right sides of the tension spring 62 are fixedly connected to the right side of the slider 42 and the surface of the telescopic rod 61, respectively. The handle 63 is fixedly connected to the front end of the groove plate 43. The moving mechanism 7 is fixedly connected to the left and right sides of the top of the bracket 1.

[0023] As a technical optimization of this utility model, by setting the auxiliary mechanism 6, the handle 63 can be pushed to the right. The movement of the handle 63 to the right drives the slider 42 and the groove plate 43 to move synchronously. When the slider 42 moves, it squeezes and contracts the telescopic rod 61. The contraction of the telescopic rod 61 compresses and stores the elastic kinetic energy of the tension spring 62 on the surface, thereby achieving the function of active reset and avoiding the inability of the telescopic rod 61 to reset after contraction, which would cause the machine to stop working continuously.

[0024] refer to Figure 5 The moving mechanism 7 includes a connecting plate 71, an electric telescopic rod 72, a cross plate 73, and casters 74. The connecting plate 71 is fixedly connected to the left and right sides of the top of the bracket 1. The electric telescopic rod 72 is fixedly connected to the center of the right side of the connecting plate 71. The cross plate 73 is fixedly connected to the bottom of the electric telescopic rod 72. The front end and back end of the bottom of the cross plate 73 are movably connected to the casters 74 through bearings.

[0025] As a technical optimization of this utility model, the electric telescopic rod 72 can be made to work by setting the moving mechanism 7. The working of the electric telescopic rod 72 pushes the horizontal plate 73 and the universal wheel 74 to move downwards synchronously. The universal wheel 74 moves downwards to contact the ground and lifts the bracket 1 away from the ground, thereby realizing the function of movement and avoiding the inability to move the bracket 1 quickly when it needs to be moved.

[0026] refer to Figure 5 A sleeve plate 8 is fixedly connected to the top and bottom of the right side of the connecting plate 71 and sleeved on the surface of the electric telescopic rod 72. The sleeve plate 8 is used in conjunction with the electric telescopic rod 72.

[0027] As a technical optimization of this utility model, the sleeve plate 8 can assist the electric telescopic rod 72 in its work and also play a fixing role, preventing the electric telescopic rod 72 from shaking due to excessive load during operation.

[0028] refer to Figure 3 The front and back ends of the top of the handle 63 are fixedly connected with anti-slip protrusions 9. There are several anti-slip protrusions 9, which are evenly distributed.

[0029] As a technical optimization of this utility model, the anti-slip protrusions 9 can increase the frictional resistance of the handle 63, thus preventing the handle 63 from slipping during hand operation.

[0030] refer to Figure 4 The inner cavity of the magnet block 53 is provided with a through hole 10, and the magnet block 53 is used in conjunction with the iron block 51.

[0031] As a technical optimization of this utility model, by setting the through hole 10, the iron block 51 can be completely inserted through the through hole 10, avoiding the phenomenon that the iron block 51 will get stuck in the through hole 10 due to the narrow width of the through hole 10.

[0032] refer to Figure 3 The cover plate 52 has grooves on both the left and right sides of its surface, and the cover plate 52 is used in conjunction with the grooves.

[0033] As a technical optimization of this utility model, the cover plate 52 can increase the pressure points for the fingers, thus avoiding the phenomenon of slippage caused by the lack of pressure points during hand operation.

[0034] The working principle and usage process of this utility model are as follows: When using, take out the adhesive strip and place it in the center of the grooved plate 43. Then, hold the cover plate 52 and insert one end of the iron block 51 downwards, aligning it with the grooved plate 43. The iron block 51 is inserted into the grooved plate 43 through the through hole 10 and is magnetically fixed by the magnet block 53. The cover plate 52 covers the surface of the adhesive strip to fix both ends. Then, the operator holds the handle 63 and pushes it to the right. The movement of the handle 63 to the right causes the grooved plate 43, the cover plate 52, and the adhesive strip to move as a whole. When the grooved plate 43 moves, it causes the slider 42 to move accordingly. The slider 42 moves horizontally along the rectangular plate 41 and contracts and compresses the telescopic rod 61. The contraction of the telescopic rod 61 compresses the tension spring 62 on the surface, storing elastic kinetic energy. At this time, the drive motor 3 works to drive the cutting belt to move, and the grooved plate 43 drives the rubber strip through the cutting belt to complete the cutting. Then, the handle 63 is released, and the telescopic rod 61, in conjunction with the tension spring 62, releases elastic kinetic energy to reset. The telescopic rod 61 extends and pushes the slider 42 and the grooved plate 43 to move synchronously. The grooved plate 43 returns to its initial position and pulls up the cover plate 52 to expose the rubber strip inside the grooved plate 43 and remove it. The cutting operation is completed. When the bracket 1 needs to be moved, the electric telescopic rod 72 is activated. The electric telescopic rod 72 pushes the horizontal plate 73 and the universal wheel 74 downward to move. The universal wheel 74 moves downward to contact the ground and lifts the bracket 1 and the drive motor 3 to rise as a whole. Then, the bracket 1 is pushed to rotate in conjunction with the universal wheel 74 to achieve movement.

[0035] In summary, this automotive wiper blade cutting machine, through the cooperation of a bracket 1, a worktable 2, a drive motor 3, a sliding mechanism 4, a rectangular plate 41, a slider 42, a grooved plate 43, and a fixing mechanism 5, allows the rubber strip to be placed inside the grooved plate 43. The grooved plate 43 then moves under force, causing the slider 42 to follow. The slider 42 moves horizontally along the rectangular plate 41, allowing the grooved plate 43 to drive the cutting strip via the drive motor 3, thus completing the cutting operation. This ensures safe feeding, preventing accidental injury caused by the palm being too close to the cutting strip. It also solves the problem of existing rubber strip cutting machines requiring manual feeding and cutting, which lacks protection for the operator's hands and easily leads to accidents.
