[0002] At present, metal products such as metal boxes, metal cabinets, and metal shells are all formed by splicing and assembling metal sheets. Before the production of the above-mentioned metal products, it is necessary to first perform a rolling process on the metal sheets of a specified size so that the metal sheets can be formed into a specified shape for easy splicing and assembly.

[0003] In the related art, the production of the above-mentioned metal products includes the following steps: unwinding of raw materials, cutting of raw materials to form metal sheets, calendering of metal sheets, and splicing and assembly. The raw materials are metal coils, which are automatically unrolled by unwinding machines. In the related art, the production of the above-mentioned metal products has begun to introduce fully automatic or semi-automatic technology, which has greatly improved production efficiency.

[0004] With respect to the above-mentioned related technologies, the applicant has found that when introducing fully automatic or semi-automatic technology, the main factor affecting production efficiency is the replenishment of raw materials.

After the new raw materials are replaced, the automatic equipment will be restarted. Therefore, if the replenishment of raw materials can be accelerated, the production efficiency of metal products can be further improved. Summary of the invention

Support seats 13 are provided at both ends of the upper sides of the two side frames 12. A groove 131 with a semicircular cross-section is provided on the upper side of each support seat 13; wherein, the two ends of the unwinding shaft 2 can be respectively placed in the two grooves 131 with overlapping axes, thereby realizing the rotational connection between the unwinding shaft 2 and the frame 1.

[0039] Among them, ball bearings can be installed at both ends of the unwinding shaft 2, and the inner ring of the ball bearing is fixedly connected to the unwinding shaft 2. When the unwinding shaft 2 is connected to the frame 1, the outer wall of the ball bearing fits with the groove 131, thereby making the rotation connection between the unwinding shaft 2 and the frame 1 smoother.

[0040] Reference Figure 3 The driving machine 3 is located between the installation positions of the two unwinding shafts 2. The driving machine 3 includes a carrying plate 31, a reversing gear box 32 and a servo motor 33. The carrying plate 31 can be slidably installed on one of the long sides of the base frame 11, and the sliding direction of the carrying plate 31 is set along the length direction of the base frame 11. The reversing gear box 32 is fixedly installed on the upper surface of the carrying plate 31. The input end of the reversing gear box 32 is upward and vertically arranged, the output end of the reversing gear box 32 is horizontal and arranged toward the middle of the frame 1, and the output shaft of the reversing gear box 32 is parallel to the axis of the unwinding shaft 2 installed on the frame 1.

The two guide rods 34 enclose a sliding groove 341 with a "convex" cross-section. The supporting plate 31 is installed in the bottom of the sliding groove 341, and the two ends of the supporting plate 31 are respectively slidably clamped in the two guide rods 34, so that the supporting plate 31 can only slide along the length direction of the base frame 11.

[0042] Reference Figure 2 and Figure 3 Two eccentric wheels 5 are rotatably connected to the base frame 11, and the rotation axes of the two eccentric wheels 5 are vertically arranged. The two eccentric wheels 5 are arranged along the length direction of the base frame 11, and the two eccentric wheels 5 are respectively arranged on the two ends of the driving machine 3. Connecting sleeves 52 are arranged on the upper surfaces of the two eccentric wheels 5, and the axes of the connecting sleeves 52 are horizontally arranged, and the vertical plane where the axes of the connecting sleeves 52 are located is perpendicular to the vertical plane where the radial lines of the eccentric wheels 5 are located; wherein, engaging wheels 311 are rotatably connected to the two ends of the bearing plate 31, and the outer walls of the two eccentric wheels 5 are respectively abutted against the outer walls of the two engaging wheels 311.

[0043] Among them, a plurality of gear holes 51 are arranged on each eccentric wheel 5, and each gear hole 51 is equidistantly arranged around the axis of the eccentric wheel 5. Two positioning holes (not shown in the figure) are arranged on the base frame 11. Positioning rods (not shown in the figure) are inserted into the corresponding gear holes 51 on each eccentric wheel 5, and the lower ends of the two positioning rods are respectively inserted into the two positioning holes to respectively fix the two eccentric wheels 5, so that the eccentric wheel 5 will not rotate due to vibration or force.

[0044] When the staff needs to rotate the eccentric wheel 5, one end of the straight rod or the "L"-shaped rod can be inserted into the connecting sleeve 52, and then force is applied to the end of the straight rod or the "L"-shaped rod away from the connecting sleeve 52, so that the straight rod or the "L"-shaped rod can drive the eccentric wheel 5 to rotate. When the eccentric wheel 5 rotates, it can push the driving machine 3 to translate along the length direction of the frame 1.

The horizontal height of the second bracket 6 is the same as that of the first bracket 4 located at the lowest point. When the raw material is unrolled, it will fall on the corresponding first bracket 4, and then after the first bracket 4 is output, it will fall on the second bracket 6. The second bracket 6 here can extend the traction path of the raw material, making it less likely that the raw material in use will interfere with the unused raw material.

[0047] The implementation principle of the embodiment of the present application is:

[0048] In the initial state, the raw materials can be placed on both unwinding shafts 2, and then the two unwinding shafts 2 are respectively installed on the two ends of the frame 1, and the two rolls of raw materials are unwound respectively, so that the unwound parts of the two rolls of raw materials are respectively placed on the two first brackets 4, and finally one of the unwinding shafts 2 is connected to the driving machine 3 by means of a transmission belt 8, so that the driving machine 3 can control the unwinding of the unwinding shaft 2.

[0049] When the material on one of the unwinding shafts 2 is used up, the unwinding shaft 2 can be immediately separated from the transmission belt 8, and then the transmission belt 8 can be separated from the other unwinding shaft 2, so that the other unwinding shaft 2 can immediately start unwinding. During the unwinding of the second unwinding shaft 2, the first unwinding shaft 2 can be removed and then new material can be reinstalled. After the installation of the material is completed, it can continue to be placed on the frame 1 for standby.

[0050] Embodiment 2:

[0052] Specifically, a block 823 with a convex cross-section is provided on two opposite side surfaces of the connecting portion 822, and a slot 813 with a convex cross-section is provided on the side surfaces of the two thickened portions 811, and the length direction of the slot 813 extends along the thickness direction of the main belt body 81, and the two ends of the two slots 813 are respectively connected to the two side surfaces of the main belt body 81; wherein, when the connecting member 82 is connected to the main belt body 81, the two blocks 823 are respectively clamped in the two slots 813.

[0054] By adopting the above method, even if the unwinding shaft 2 has been installed on the frame 1, the staff can separate the main belt body 81 from the connecting piece 82 so that the transmission belt 8 can be separated from the unwinding shaft 2 installed on the frame 1, making it convenient for the staff to connect the transmission belt 8 and the unwinding shaft 2 alone.
