Detailed implementation manners

[0045] The present utility model will be further described in detail below in conjunction with the accompanying drawings through specific implementation manners.

[0046] Embodiment 1

[0047] As Figure 1 shown, this embodiment provides a disassembly and assembly tool for the lower paper cutting assembly of the transparent paper of the small box of the ZB48A packaging machine, including: a tooling vehicle body, a mounting plate 5, a lifting assembly, and an adjusting assembly. When in use, the tooling vehicle body is moved to the front of the lower paper cutting assembly of the transparent paper of the small box of the ZB48A packaging machine. The height of the mounting plate 5 is adjusted through the lifting assembly so that the connecting holes thereon are aligned with the screw holes on the back plate of the lower paper cutting assembly 7 of the transparent paper. Then, the mounting plate 5 is moved forward by using the adjusting assembly so that it is closely attached to the back plate of the lower paper cutting assembly 7 of the transparent paper. After being fixed with screws, the lower paper cutting assembly 7 of the transparent paper can be removed. During installation, the reverse operation can be performed. Through this disassembly and assembly tool, the disassembly and assembly difficulty of the lower paper cutting assembly 7 of the transparent paper can be effectively reduced, and the efficiency and safety can be improved.

[0048] Specifically, as Figures 2-3 shown, the tooling vehicle body includes: a base 1, and universal wheels 11 are provided at the bottom of the base 1 for the movement of the tooling. The lifting assembly includes a lifting bracket 2 and a slide seat 3. The lifting bracket 2 includes a vertical plate 22 and a horizontal plate 21. The horizontal plate 21 is connected to the base 1 through a lever mechanism. The vertical plate 22 is arranged on the horizontal plate 21, and the two form a "⊥" shape. A vertically arranged long slotted hole 24 and a dovetail groove 25 are provided on the vertical plate 22. Screws pass through the long slotted hole 24 and are connected to the slide seat 3. A slide block 31 is provided on the slide seat 3, and the slide block 31 is located in the dovetail groove 25. The adjusting assembly is installed on the slide seat 3, and the mounting plate 5 is arranged on the adjusting assembly. By loosening the screws, the slide seat 3 can be moved up and down, thereby driving the adjusting assembly and the mounting plate 5 thereon to perform height adjustment.

[0049] The lever mechanism includes: a crowbar 61, a first connecting member 62, and a plurality of second connecting members 63. The first connecting member 62 is provided at the end of the crowbar 61. One end of the first connecting member 62 is connected to the cross plate 21, and the other end is connected to the base 1. The plurality of second connecting members 63 are symmetrically arranged on both sides of the cross plate 21 and the base 1, and both ends of the second connecting members 63 are respectively hinged to the cross plate 21 and the base 1. As Figures 3-4 shown, when the crowbar 61 is pressed down, the first connecting member 62 is driven to move backward, causing the base 1 and the second connecting members 63 connected thereto to move accordingly. Since the ground is supported by the universal wheels 11, the height of the lifting bracket 2 will decrease, and further the feet 23 of the cross plate 21 will support on the ground, ensuring the stability of the tooling during the loading and unloading process. On the contrary, when the crowbar 61 is pulled up, the height of the lifting bracket 2 will rise, and further the feet 23 will be separated from the ground, facilitating the movement of the tooling. A stop block 64 is provided at the bottom of the cross plate 21. When the height of the cross plate 21 rises, the stop block 64 moves upward and backward, and finally presses on the base 1. At this time, the second connecting member 63 presents an inclined state with the connecting end to the base 1 in the front and the connecting end to the cross plate 21 in the back. Under the gravity of the upper lifting assembly, adjusting assembly, and mounting plate 5, the stop block 64 is kept pressing on the base 1, thus ensuring the stability of the tooling during the movement process.

[0050] As Figure 5 shown, the adjusting assembly includes: a lead screw 41 and a plurality of slide rods 4. The lead screw 41 passes through the slide base 3 and extends forward. A handle 42 is installed at one end close to the vertical plate 22 for rotating the lead screw 41, and a stop block 43 is installed at the other end to prevent the mounting plate 5 from sliding out of the lead screw 41. The plurality of slide rods 4 are distributed below the lead screw 41, and the cross section is in a rhombus shape. A moving pair is provided on the mounting plate 5, and each moving pair corresponds to one slide rod 4. Each moving pair is composed of two connecting rods 51 distributed up and down and a bearing group on the connecting rod 51. The bearing group includes a plurality of bearings 52, and the mounting plate 5 is facilitated to move along the slide rod 4 through the bearings 52.

[0051] Specifically, the disassembly process is as follows:

[0052] (1) Disassemble the components around the lower paper cutting assembly 7 of the small box transparent paper.

[0053] (2) Push the tooling in so that the base 1 of the tooling is inserted under the machine. The vertical plate 22 is basically aligned with the lower paper cutting assembly of the small box transparent paper, and use the crowbar 61 to lower the height of the cross plate 21, and use the feet 23 to support the tooling.

[0054] (3) Loosen the screws on the slide base 3, adjust the height of the slide base 3 so that the mounting plate 5 is aligned with the lower paper cutting assembly 7 of the small box transparent paper, and then tighten the screws.

[0055] (4) Rotate the handle 42 to adjust the front and back position of the mounting plate 5 so that it closely adheres to the back plate of the lower paper cutting assembly 7 of the small box transparent paper.

[0056] (5) Open the cover plate of the rear box of the machine and loosen the drive toothed belt of the assembly.

[0057] (6) Loosen the fixing screws of the assembly and the frame. At the same time, insert the fixing screws synchronously on the mounting plate 5 to fix the lower paper cutting assembly 7 of the small box transparent paper and the mounting plate 5.

[0058] (8) Rotate the handle 42 to move the mounting plate 5 backward, smoothly pull out the assembly from the machine, lift the cross plate 21 with a crowbar, and pull out the tooling together with the assembly mounted on it for maintenance.

[0059] Installation process:

[0060] (1) After repairing the lower paper cutting assembly 7 of the small box transparent paper, push the tooling in so that the tooling base 1 is inserted under the machine.

[0061] (2) Since the height of the slide block 3 remains unchanged, the height of the assembly is the same as that during disassembly. Only slide the left and right positions of the tooling to align the pin holes and the positioning pins, and then the assembly can be pushed in.

[0062] (3) Remove the fixing screws of the mounting plate 5 and the assembly, and synchronously insert the fixing screws of the assembly and the machine.

[0063] (4) Install the drive toothed belt of the assembly in the rear box of the machine, tension the toothed belt, and install the cover plate of the rear box of the machine.
