[0043] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0044] Example

[0045] like Figure 1-2 As shown, an automatic nozzle cutting machine for toy tire production includes a frame 1, a first translation material rack 2 movably mounted above the frame 1, a second translation material rack 3 movably mounted inside the frame 1 and capable of being raised and lowered to avoid the first translation material rack 2, and a laser cutting mechanism 4 located above the front end of the frame 1.

[0046] like Figure 3-11 As shown, the frame 1 includes a base 11, outer plates 12 fixedly installed on both sides of the base 11 for supporting the first translational material rack 2, inner plates 13 fixedly installed on both sides of the base 11 for supporting the second translational material rack 3, a lifting guide plate 14 fixedly installed inside the base 11 for acting on the second translational material rack 3, a screw device 15 installed on the outer side of the upper end of one of the outer plates 12 for driving the first translational material rack 2, and a belt driving device 16 installed on the middle inner side of the other outer plate 12 for driving the second translational material rack 3.

[0047] Specifically, the base 11 serves as the foundation of the entire frame and can provide a stable support and structural foundation. The outer plate 12 and the inner plate 13 are fixed on the base 11, respectively supporting the first translation material rack 2 and the second translation material rack 3, ensuring the stability and smooth movement of the material racks, and playing an effective supporting role. Furthermore, in addition to supporting the second translation material rack 3, the inner plate 13 is also equipped with a lifting guide plate 14, which can effectively guide the vertical movement of the second translation material rack 3, increasing the accuracy and controllability of the operation.

[0048] It should be further explained that the first translation rack 2 is driven by a screw device 15, which can usually provide higher precision and stability, and is suitable for applications that require accurate position control. The second translation rack 3 uses a belt drive device 16, which can usually provide faster movement speed and greater load capacity, and is suitable for scenes that require frequent movement and large loads.

[0049] In the structure of the frame 1, the upper end of the outer plate 12 is fixed with a first translation rack translation rail 121 by bolts, and the upper end of the inner plate 13 is fixed with a second translation rack translation rail 131 by bolts. Specifically, it is beneficial for the first translation rack 2 and the second translation rack 3 to move alternately, replacing a complex transmission belt structure.

[0050] In the structure of the frame 1, a guide groove 141 is provided on the lifting guide plate 14, and the guide groove 141 includes an alternating avoidance section 141a, a guide groove slope section 141b inclined upward from both ends of the alternating avoidance section 141a, and a guide groove translation section 141c straightened from the upper end of the guide groove slope section 141b.

[0051] It should be further explained that when the guide wheel 36 moves in the guide groove 141, the guide wheel 36 moves downward through the guide groove slope section 141b and enters the alternating avoidance section 141a, so that the second translation material rack 3 and the first translation material rack 2 alternate, or the guide wheel 36 moves upward and disengages from the alternating avoidance section 141a, so that the second translation material rack 3 and the first translation material rack 2 alternately rise after completing, and enter the guide groove translation section 141c and are on the same horizontal line with the first translation material rack 2, so as to facilitate loading and unloading.

[0052] In the structure of the frame 1, the screw device 15 includes a screw mounting frame 151 fixedly mounted on the outer plate 12, a screw 152 movably mounted on the screw mounting frame 151 through a fixed bearing, a moving block 153 assembled on the screw 152 and assembled with the first translation material rack 2, and a screw motor 154 mounted on the outside of the screw mounting frame 151 and fixedly connected to the screw 152 at the output end. Specifically, the screw motor 154 drives the screw 152, and utilizes the moving block 153 assembled with the first translation material rack 2 to drive the entire first translation material rack 2 to translate.

[0053] In the structure of the frame 1, the belt driving device 16 includes a plurality of fixed shafts 161 fixedly mounted on the outer plate 12, a driven gear 162 mounted on the fixed shaft 161, a toothed belt 163 meshed with the driven gear 162, a toothed belt tensioning frame 164 mounted on the outer plate 12, a tensioning wheel 165 supported and mounted by the toothed belt tensioning frame 164 and capable of contacting the toothed belt 163, a forward and reverse motor 166 fixedly mounted on the outer plate 12, and a driving gear 167 mounted on the output end of the forward and reverse motor 166 and meshed with the toothed belt 163. Specifically, since the belt pressing block 314 cooperates with the supporting arm 313 to squeeze the fixed toothed belt 163, the forward and reverse motor 166 can be used to drive the driving gear 167, so that the toothed belt 163 drives the second translation material rack 3 to reciprocate on the inner plate 13. At the same time, under the guiding action of the lifting guide plate 14, the second translation material rack 3 can move alternately with the first translation material rack 2.

[0054] The first translation material rack 2 includes a first translation plate body 21, a first translation plate body slide rail seat 22 fixedly installed below the first translation plate body 21 by bolts and corresponding to the outer plate 12, a right-angle frame 23 fixedly installed on one side of the first translation plate body 21 by bolts, and a first translation material rack material tray 24 clamped above the first translation plate body 21 and used for loading and unloading materials respectively.

Specifically, the belt pressure block 314 squeezes the toothed belt 163, and can drive the entire second translational material rack 3 to move through the driving plate 31.

[0060] In the structure of the second translation material rack 3, the sleeve 32 is a steel cylinder with steel balls embedded inside. Specifically, the limiting column 33 is clearance-matched with the sleeve 32 and supported by the internal steel column. During actual operation, the steel balls cooperate with lubricating oil to enable the limiting column 33 to move flexibly up and down in the sleeve 32.

[0061] In the structure of the second translation material rack 3, an anti-dropout plate 331 is fixed by bolts below the limiting column 33 on the same side of the second translation material rack 3. Specifically, the anti-dropout plate 331 can prevent the limiting column 33 from detaching during the movement process.

[0062] In the structure of the second translational material rack 3, a second translational material rack support plate mounting hole 341 is opened on the second translational material rack support plate 34, and the bottom of the second translational material rack material tray 37 is integrally formed with a second translational material rack material tray protrusion 371 corresponding to the second translational material rack support plate mounting hole 341.
