Description

Technical Field

[0001] This utility model relates to a film winding device, specifically to an automatic dicing and winding machine for EPE sheets. Background Technology

[0002] EPE, or expanded polyethylene, is a lightweight, flexible, non-porous foam structure widely used due to its excellent cushioning and shock absorption, lightweight and environmentally friendly properties, corrosion resistance, sound and heat insulation, and ease of processing. EPE sheets are a type of EPE product, appearing as thin sheets. After processing, they need to be flattened by a traction machine, cut to the required size, and wound into rolls. Finally, they are packaged and transported using a winding machine. Currently, workers use winding machines for this purpose, requiring careful control of the winding speed. Excessive speed can stretch the sheet and cause breakage, while insufficient speed can lead to overlapping during winding. Furthermore, different thicknesses of EPE sheets require different operating parameters, demanding high operational skill and increasing the risk of errors, resulting in low work and production efficiency.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0019] according to Figure 1 , Figure 2 As shown, an automatic EPE sheet dicing and winding machine in this solution includes a frame 100. The frame 100 includes a base 1 and two columns 2 symmetrically arranged at both ends of the base 1. Inclined beams 3 are provided between the two ends of the columns 2 and the base 1. A crossbeam 4 is connected between the upper and lower parts of the two columns respectively.

[0020] The frame 100 has symmetrically arranged rotating arms 101, rotating arm cylinders 102, curved arms 103, curved arm cylinders 104, rocker arms 105, rocker arm cylinders 106, and slicing cylinders 107 on the two end columns 2. Specifically, the tops of the two columns 2 are respectively fixed with first bearings 116, and the two ends of the first rotating shaft 110 are inserted into the first bearings 116 for rotation. The rotating end of the rotating arm 101 is interference-fitted to the end near the first rotating shaft 110.

[0021] The free end of the rotating arm 101 is hinged to the rotating end of the crank arm 103, which has a C-shaped structure. A first roller 108 is provided between the other free ends of the two crank arms 103. One end of the rocker arm 105 is hinged to the middle part 101 of the rotating arm, and a second roller 109 is provided between the other ends of the two rocker arms. A first rotating shaft 110 is provided between the rotating ends of the two rotating arms 101, and a second rotating shaft 111 is provided between the free ends of the two rotating arms 101. In this embodiment, a second bearing 117 is bolted to the inner side of each of the two rotating arms 101, and the end of the second rotating shaft 111 is located inside the bearing 117.

[0022] The base of the rotating arm cylinder 102 is hinged to the support 114, which is fixedly mounted on the column 2. The piston rod at the other end of the rotating arm cylinder 102 is hinged to the front middle part of the rotating arm 101. The base of the crank arm cylinder 104 is hinged to the rotating arm 101 at one end and to the piston rod at the other end of the connecting rod 112 at one end. The other end of the connecting rod 112 is bolted to one end of the crank arm 103. The base of the rocker arm cylinder 106 is hinged to the rotating arm 101 at one end and to the piston rod at the other end of the rocker arm 105. The base of the slicing cylinder 107 is bolted to the inner side of the crank arm 103. A slicing blade 113 is bolted between the piston rods of the two slicing cylinders 107.

[0023] As a further improvement of this embodiment, a pressure roller 115 is provided above the front end of the slicing blade 113, and the two ends of the pressure roller 115 are respectively hinged to the inner sides of the two curved arms 103.

[0024] The following is a schematic diagram illustrating the working principle of an automatic EPE sheet dicing and winding machine according to this utility model:

[0025] like Figure 3 As shown, in the initial state, the EPE sheet 7 comes from below the flattening roller 5 of the traction machine, passes through the automatic EPE sheet dicing and winding machine of this scheme, and arrives above the winding rod 6 of the winding machine.

[0026] like Figure 4 As shown, the piston rod of the rotating arm cylinder 102 retracts, causing the rotating arm 101 to swing down, and the first roller 108 presses down on the EPE sheet 7 behind the winding rod 6.

[0027] like Figure 5As shown, the piston rod of the crank arm cylinder 104 is pushed forward, causing the crank arm 103 to perform a hooking action. The free end of the crank arm 103 moves to the front of the take-up bar 6, while the pressure roller 115 presses down on the EPE sheet 7.

[0028] like Figure 6 As shown, at this time, the piston rod of the rocker arm cylinder 106 advances, and the rocker arm 105 swings, causing the second roller 109 to press down on the EPE sheet 7, so that it is wound onto the take-up rod 6. At this time, the slicing cylinder 107 is advanced, causing the slicing blade 113 to slice and cut the EPE sheet 7.

[0029] like Figure 7 As shown, the cut EPE sheet 7 is wound around the take-up bar 6. Then it returns to its initial state.

[0030] The above description is merely an embodiment of this utility model, and common knowledge such as specific structures and characteristics of the solution is not described in detail here. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
