[0028] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present utility model. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments

[0029] In order to enable those skilled in the technical field to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings

[0030] As Figures 1-4 shown, it is an embodiment provided by the present utility model

[0031] An embodiment of the present utility model provides a rubber material slitting mechanism, including: a mounting shell 10, a first cutter group 20 and a second cutter group 30. The first cutter group 20 and the second cutter group 30 are spaced and mounted in the mounting shell 10. Specifically, the first cutter group 20 includes a first sliding rod 21, a plurality of first cutter seats 22 and a plurality of first hob cutters 23. The first cutter seats 22 are slidably mounted on the first sliding rod 21, and the first hob cutters 23 are rotatably mounted at the front ends of the first cutter seats 22 one by one. During the conveying process of the sheet-shaped rubber material, the first hob cutters 23 pass over the rubber material and slit the rubber material into strips. Similarly, the second cutter group 30 includes a second sliding rod 31, a plurality of second cutter seats 32 and a plurality of second hob cutters 33. The second cutter seats 32 are slidably mounted on the second sliding rod 31, and the second hob cutters 33 are rotatably mounted at the front ends of the second cutter seats 32 one by one. Compared with the first cutter group 20, the second cutter group 30 is farther from the inlet of the rubber material, that is, the rubber material passes through the first cutter group 20 first and then through the second cutter group 30. Among them, the first sliding rod 21 is parallel to the second sliding rod 31, and the plurality of first hob cutters 23 and the plurality of second hob cutters 33 are parallel to each other, capable of neatly slitting the rubber material. The orthographic projection of the first hob cutters 23 on the plane where the second hob cutters 33 are located does not intersect with the second hob cutters 33, so that the first hob cutters 23 and the second hob cutters 33 can be moved and adjusted at will without interfering with each other. When slitting the rubber material, the first hob cutters 23 and the second hob cutters 33 can cooperate with each other without being restricted by the first cutter seats 22 and the second cutter seats 32. Compared with the prior art in which the minimum width of the rubber strip slitting is limited by the width of two adjacent cutter seats, the rubber material slitting mechanism in this embodiment has a larger selection range for the slitting width of the rubber strip, can cut out thinner and narrower rubber strips, and makes the applicability of the rubber material slitting mechanism stronger. In addition, compared with the prior art in which only one cutter group is used for slitting, the rubber material slitting mechanism in this embodiment has two cutter groups, and can slit out twice the amount of rubber strips of a single cutter group under mutual cooperation, and the production efficiency can also be greatly improved.

[0032] Specifically, the plurality of first hob cutters 23 and the plurality of second hob cutters 33 are arranged in an interleaved manner. The number of the first hob cutters 23 is the same as that of the second hob cutters 33, and the radius of the first hob cutters 23 is the same as that of the second hob cutters 33, which can more conveniently slit the rubber material.

[0033] Further, scale rulers 40 are respectively arranged on the first sliding rod 21 and the second sliding rod 31, which is convenient for accurately controlling the movement of the first hob cutters 23 and the second hob cutters 33 and adjusting the interval between adjacent first hob cutters 23 and second hob cutters 33.

[0034] Furthermore, the cross-sections of the first sliding rod 21 and the second sliding rod 31 are both "D"-shaped. The rear end of the first tool holder 22 is sleeved on the first sliding rod 21, which can prevent the first tool holder 22 from rotating circumferentially along the first sliding rod 21. The rear end of the second tool holder 32 is sleeved on the second sliding rod 31, which can prevent the second tool holder 32 from rotating circumferentially along the second sliding rod 31, ensuring the stability of the first hob 23 and the second hob 33 during material cutting.

[0035] Specifically, the first tool holder 22 and the second tool holder 32 do not intersect and will not interfere with each other during movement. The width of the first tool holder 22 is the same as that of the second tool holder 32, which is convenient for unifying the specifications of components and reducing the equipment cost.

[0036] Furthermore, the first tool holder 22 is generally "d"-shaped as a whole, and the first hob 23 is arranged on the left side of the front end of the first tool holder 22. The second tool holder 32 is generally "b"-shaped as a whole, and the second hob 33 is arranged on the right side of the front end of the second tool holder 32.

[0037] Specifically, two pressure rollers 11 are rotatably installed in the installation shell 10. The two pressure rollers 11 are arranged at intervals and are parallel to each other, which can extrude the rubber material into a sheet shape. The first hob 23 and the second hob 33 are simultaneously tangent to the roller surface of one of the pressure rollers 11, which can completely cut off the rubber material, so that the cut rubber strips will not stick to each other.

[0038] Obviously, the embodiments described above are only a part of the embodiments of the present invention, rather than all of them. The drawings show the preferred embodiments of the present invention, but do not limit the patent scope of the present invention. The present invention can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosed content of the present invention more thorough and comprehensive. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing specific embodiments, or perform equivalent replacements for some of the technical features. Any equivalent structures made directly or indirectly using the specification and drawings of the present invention in other related technical fields are equally within the scope of the patent protection of the present invention.
