Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of devices for EVA boards, in particular to a collecting device for batch cutting of EVA boards. Background Art
[0002] The EVA board is a new type of board, and due to its excellent earthquake resistance, heat insulation, chemical corrosion resistance and other properties, it has been widely used in various industries.
[0003] When producing long-strip EVA boards, usually a whole EVA board is first produced, and then according to the data required for production, a whole EVA board is cut into strips by a slitting machine. After that, the strip-shaped EVA boards are collected. In order to conveniently organize and transport these EVA board strips, and considering that the EVA board itself has good flexibility, the current collection method uses two solid material rollers to clamp one end of the EVA board, and the EVA board is wound into a disc shape by rotating the solid material rollers. In this way, two solid material rollers can process multiple EVA board strips at the same time, thereby effectively improving the collection efficiency of the EVA board strips; and when the EVA board strips are almost completely wound, a pressing roller is used to fix the other end of the EVA board, and then the other end of the EVA board is fixed uniformly with tape, and then a tool is used to cut the tape; this can quickly fix the disc-shaped EVA board and prevent it from loosening, and finally the disc-shaped EVA board can be removed from the solid material roller.
[0004] However, when the above method is used, since the EVA board strips are arranged relatively closely, when cutting the tape with a tool, the tool is very easy to deviate and cut the EVA board, resulting in a significant increase in the loss rate of the EVA board, thereby reducing the production efficiency. Summary of the Utility Model

[0018] To make the objectives, technical solutions, and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.
[0019] Embodiment: A collecting device for batch cutting of EVA boards, in combination with Figures 1 - 3 , comprising: a mounting frame 2, a material-fixing roller 3, a partition 4, a positioning block 5, and a fixing member 6; the mounting frame 2 is placed on the front side of the outlet of the slitting machine 1; turntables are provided on both sides of the mounting frame 2, and a motor is provided on the right side of the mounting frame 2. The output end of the motor is fixed to the turntable on the right side. Two material-fixing rollers 3 are installed between the two turntables of the mounting frame 2 for fixing one end of the EVA board strip. The material-fixing roller 3 is installed in an inserted manner with the turntable, enabling the material-fixing roller 3 to be freely disassembled from the turntable of the mounting frame 2; a partition 4 for separating the EVA board strips is slidably installed on the material-fixing roller 3. There are twenty-one partitions 4, enabling the material-fixing roller 3 to coil twenty EVA board strips at the same time; a positioning block 5 is slidably installed at the right end of the material-fixing roller 3, and the positioning block 5 restricts the position of the partition 4 on the material-fixing roller 3; a fixing member 6 is provided on the positioning block 5. The fixing member 6 is a bolt, and the fixing member 6 is threadedly connected to the positioning block 5 and contacts the material-fixing roller 3.
[0020] In combination with Figures 1 - 3 , comprising: a mounting block 9, a return spring 10, a pressure roller 11, and a handle 13; mounting blocks 9 are slidably installed on the left and right sides of the mounting frame 2; a return spring 10 is fixedly installed between the mounting block 9 and the mounting frame 2; a pressure roller 11 is fixedly installed between the two mounting blocks 9; a handle 13 is installed between the two mounting blocks 9, and the handle 13 is located above the pressure roller 11.
[0021] When using this device to collect the EVA strips slit by the slitter 1, remove the solid material roller 3, sandwich the slit EVA strips between the solid material rollers 3, and place the EVA strips correspondingly between the partitions 4. After completion, fix the solid material roller 3 back on the mounting frame 2. Then, slide the positioning block 5 and push the positioning block 5 towards the partition 4 to make each partition 4 closely adhere to each EVA strip. After completion, rotate the fixing member 6 to fix the position of the positioning block 5. Subsequently, control the rotation of the solid material roller 3 through the mounting frame 2, and the EVA strips are coiled into a disk shape. As the diameter of the coiled EVA strips increases, the EVA strips squeeze the pressure roller 11 to move upward, and the return spring 10 is compressed. Then, under the action of the return spring 10, the pressure roller 11 presses and fixes the EVA strips on the solid material roller 3 to prevent the EVA strips from spreading. After that, when the EVA strips are completely coiled on the solid material roller 3, stop rotating the solid material roller 3, use tape to fix the other ends of all the EVA strips to the coiled EVA strips at one time to achieve rapid sealing, and then use a cutter to cut the tape. At this time, due to the partitioning effect of the partition 4, there are gaps between the coiled EVA strips, so the cutter is not likely to scratch the EVA strips, thereby reducing the loss of EVA strips and achieving the effect of improving the production efficiency of EVA strips. Finally, use the handle 13 to move the pressure roller 11 upward, remove the solid material roller 3 from the mounting frame 2, and push the partition 4 away from the solid material roller 3, then all the EVA strips can be removed from the solid material roller 3. Moreover, the partition 4 enables the coiled EVA strips to be smoothly unloaded from the solid material roller 3, preventing the EVA strips from spreading due to friction when the EVA strips are discharged, improving the material collection effect, and completing the neat collection of EVA strips at this time.
[0022] Combined with Figure 1 、 Figure 2 and Figure 4 it also includes: a bracket 7, a guide plate 8 and a roller 12; a bracket 7 is fixedly installed at the rear of the mounting frame 2; a guide plate 8 is fixedly installed on the bracket 7, and the intervals on the guide plate 8 correspond one by one to the intervals between the partitions 4; a roller 12 is rotatably installed on the guide plate 8, and the roller 12 is in rolling contact with the EVA strips. When the EVA strips are coiled on the solid material roller 3, the guide plate 8 separates each EVA strip, enabling each EVA strip to be better coiled independently, preventing adhesion between the EVA strips, and avoiding the problem of reduced coiling effect of the EVA strips. The roller 12 can reduce the friction between the EVA strips and the guide plate 8, thereby reducing the influence of the guide plate 8 on the coiling of the EVA strips.
[0023] Combined with Figure 1 it also includes: a spacer sleeve 14; a spacer sleeve 14 is sleeved outside the return spring 10, and the spacer sleeve 14 can prevent debris from getting stuck in the return spring 10 to avoid affecting the normal pressing function of the pressure roller 11.
[0024] Combined withFigure 1 , and also includes: a spacer 15; a spacer 15 is fixedly installed on the side of the partition 4 that contacts the EVA strip, so that the spacer 15 can be deformed in advance during the process of the partition 4 and the EVA strip being in close contact, thereby preventing the EVA strip from deforming, allowing the EVA strip to be coiled straight, thereby improving the coiling effect of the EVA strip.

These descriptions are only for explaining the principles of the embodiments of the present utility model, and cannot be interpreted in any way as limiting the protection scope of the embodiments of the present utility model.
