DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0024] like Figure 1-3 The cutter assembly shown in the figure includes a toggle gear 10, a cutter seat disc 20 and a blade disc 30 having a blade 33; the blade disc 30 and the toggle gear 10 are disposed on opposite sides of the cutter seat disc 20 and are respectively fixed on the cutter seat disc 20, so that the blade disc 30 and the toggle gear 10 are fixedly connected; the cutter seat disc 20, the blade disc 30 and the toggle gear 10 are coaxially arranged; the blade 33 extends out of the cutter seat disc 20, so that the blade 33 is not affected by the cutter seat disc 20 and ensures that the blade 33 contacts the tire, thereby achieving cutting; in actual During operation, the blade disc and another external blade disc cooperate to engage the tire to drive the tire to rotate and cooperate to cut the tire; the toggle gear 10 is used to rotate with the cutter seat disc 20 when the blade disc 30 rotates to cut the tire, so that the tooth portion 11 of the toggle gear drives the tire to rotate relative to the blade disc 30, that is, further drives the tire to rotate in the opposite direction of the cutting direction, avoiding idling of the blade disc and improving cutting efficiency; specifically, the tire rotates around its central axis, and at this time, cooperates with the tire rotation during the rotation and cutting process of the blade disc 30.

[0025] Furthermore, the diameter of the toggle gear 10 is smaller than the diameter of the blade disc 30, so that when the toggle gear 10 pushes the tire, it is further ensured that the blade disc 30 can be inserted into the tire to cut the tire; further, the diameter of the toggle gear 10 is larger than the diameter of the blade seat disc 20.

[0026] The tooth portion 11 of the shifting gear mentioned above extends toward the rotation direction of the blade disc 30, further ensuring the shifting of the tire.

[0027] The diameter of the blade disk 30 is greater than the diameter of the blade seat disk 20 , so that the blade edge 33 is ensured to protrude outside the blade disk 30 .

[0028] In order to facilitate the coaxial arrangement of the tool seat disc 20 and the blade disc 30, preferably, a positioning structure 40 is arranged between the tool seat disc 20 and the blade disc 30; the positioning structure 40 includes a positioning block 41 and a positioning groove 42; one of the positioning block 41 and the positioning groove 42 is arranged on the tool seat disc 20, and the other is arranged on the blade disc 30; the positioning groove 42 and the positioning block 41 are matched and inserted so that the central axes of the tool seat disc 20 and the blade disc 30 coincide with each other, thereby realizing the coaxial arrangement of the tool seat disc 20 and the blade disc 30, without the need for manual visual judgment and multiple position adjustments, thereby simplifying the installation procedure.

[0029] The present invention discloses a further implementation of the positioning structure 40. Specifically, the positioning groove 42 is opened on the blade disc 30, and the positioning block 41 is arranged on the blade seat disc 20; more specifically, the positioning groove 42 is coaxially arranged with the blade disc 30, and the positioning block 41 is coaxially arranged with the blade seat disc 20, so that after the positioning groove 42 is inserted into the positioning seat, the blade disc 30 and the blade seat disc 20 are coaxially arranged; of course, the positioning structure 40 can also adopt the following implementation mode. Specifically, the positioning groove 42 is opened on the blade seat disc 20, and the positioning block 41 is arranged on the blade disc 30; more specifically, the positioning groove 42 is coaxially arranged with the blade seat disc 20, and the positioning block 41 is coaxially arranged with the blade disc 30.

[0030] The present invention also discloses another embodiment of the positioning structure 40, wherein the positioning block 41 is a non-equilateral right triangle or other irregular shapes, etc., and the positioning groove 42 is also a non-equilateral right triangle or other irregular shapes, etc. having the same shape as the positioning block 41. In this way, by matching the positioning groove 42 and the positioning, the relative positioning of the blade disc 30 and the blade seat disc 20 can be achieved, thereby achieving the coaxial setting of the two.

[0031] Furthermore, the blade disc 30 and the blade seat disc 20 are fixedly connected by a locking structure 50; the locking structure 50 includes a first socket 51 opened on the blade seat disc 20, a second socket 52 opened on the blade disc 30, a screw and a nut; the rod of the screw passes through the first socket 51 and the second socket 52, and is threadedly engaged with the nut, thereby locking the blade seat disc 20 and the blade disc 30. At this time, the blade seat disc 20 and the blade disc 30 can be replaced by unscrewing the screw and the nut.

[0032] Since the tire contains materials with relatively high hardness such as steel wire, preferably, the blade disc 30 is in the shape of a truncated cone; the upper bottom surface of the blade disc 30 faces the blade seat disc 20; the angle ∠A between the lower bottom surface 31 of the blade disc and the side surface 32 of the blade disc is 40-50°, and a blade 33 is formed at the intersection of the lower bottom surface 31 of the blade disc and the side surface 32 of the blade disc. At this time, the blade 33 of the blade disc 30 is relatively sharp, and the thickness of the blade disc 30 is sufficient, thereby avoiding its cracking due to cutting materials such as steel wire.

[0033] Preferably, the angle ∠A is 48°.

[0034] The present invention further discloses a cutter mechanism, including a bracket 60 , a rotary motor 70 and the above-mentioned cutter assembly; the body of the rotary motor 70 is fixed on the bracket 60 ; the output shaft of the rotary motor 70 is drivingly connected to the cutter seat disc 20 .

[0035] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
