[0026] In this embodiment, preferably, a limiting plate 13 is fixedly connected to the top of the side surface of the vertical rod 9 , and the limiting plate 13 limits the vertical rod 9 .
[0027] In this embodiment, preferably, the top of the gantry 3 is rotatably connected to two threaded sleeves 14, the interiors of the two threaded sleeves 14 are threadedly connected to vertical screws 15, and the two positioning frames 5 are respectively fixedly connected to the bottom ends of the two vertical screws 15; by rotating the threaded sleeves 14, the thread transmission acts on the vertical screws 15, so that the vertical screws 15 drive the positioning frames 5 to rise and fall.
[0028] In this embodiment, preferably, the tops of the two positioning frames 5 are fixedly connected with a limiting rod 16, the top of the limiting rod 16 passes through the gantry 3, and the length of the vertical screw 15 is greater than the height of the gantry 3; the positioning frame 5 is limited by the limiting rod 16, so that the positioning frame 5 moves straight up or down without deflection, and the length of the vertical screw 15 is greater than the height of the gantry 3, so that the vertical screw 15 will not separate from the threaded sleeve 14.

[0030] In this embodiment, preferably, a support platform 22 located between the two groups of conveying components 2 is fixedly connected to the inner side of the machine 1, the top of the support platform 22 is flush with the tops of the two groups of conveying components 2, and a cutting groove 23 adapted to the cutting knife 42 is opened on the top of the support platform 22; the support platform 22 is connected to the gap between the two groups of conveying components 2, and a cutting force point is given, and a cutting groove is set on it, so that the blade part of the cutting knife 42 is cut into the groove to completely cut the rubber material.
[0031] The working principle and use process of this utility model:
[0032] When slicing the rubber pad, the rubber pad is transmitted through two groups of transmission components 2, and the rotating shaft 18 is driven by the servo motor 21 to rotate the screw sleeve, which can drive the worm gear 19 to rotate and drive the threaded sleeve 14 to rotate. The threaded sleeve 14 drives the vertical screw 15 to move downward in a straight line under the restriction of the limit rod 16 through thread transmission, and the vertical screw 15 drives the positioning frame 5 to move downward and make the positioning roller 6 contact the rubber pad to level the rubber pad. Before the positioning roller 6 contacts the rubber pad, the positioning wheel 8 contacts the rubber pad before the positioning roller 6. As the positioning frame 5 descends and the positioning wheel 8 contacts the rubber pad, the relative distance between the cross plate 10 and the connecting frame is reduced, so that the spring 12 is compressed. The elastic force of the spring 12 acts on the cross plate 10, so that the positioning wheel 8 contacts the rubber pad. It can be seen that during the transmission and cutting process of the rubber pad, the rubber pad is restricted by the positioning roller 6 and the positioning wheel 8, and is effectively positioned without affecting the transmission of the rubber pad, effectively avoiding the deviation of the rubber pad during transmission, and preventing deviation during cutting to reduce the cutting accuracy.
[0033] When cutting the rubber tube, the specific operation steps are roughly the same as the above process, the difference is that the positioning wheel 8 has a movable arc, the rubber tube is correspondingly engaged on the inner side of the positioning wheel 8, and the positioning wheel 8 limits the rubber tube so that the position of the rubber tube will not deviate.
[0034] In summary, the utility model can be used for cutting rubber pads as well as rubber tubes, and has strong applicability. During cutting, the positioning roller 6 and the positioning wheel 8 are used to limit the cutting, thereby effectively avoiding the deviation of the rubber pad or rubber tube during transportation and preventing deviation during the cutting process to improve the cutting accuracy.

The electronic components and modules are all connected to an external power supply and a control switch for use. Their specific circuit connection methods and methods of use are commonly used public technologies and will not be elaborated on here.
[0036] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
