[0002] Foam shock-absorbing sheets are environmentally friendly, and have the properties of cushioning, shock resistance, heat insulation, and protection. They are widely used in various industries such as electronics, medical, and automotive, and are becoming more and more popular in the market.

[0003] The processing of foam shock-absorbing sheets requires the allocation and proportioning of raw materials, foaming, hardening and cutting.

[0028] In order to achieve accurate lateral positioning of the foam damping sheet 2 by the pressing member and prevent the pressing member from deviating during the rotation process, as shown in FIG. Figure 4 As shown, in this embodiment, a groove 41b is provided on the support plate, and a first protrusion 41a corresponding to the groove 41b on the support plate is provided on the sliding block. The moving rod pushes the sliding block to move. At this time, the first protrusion 41a moves linearly along the groove 41b on the support plate, further improving the movement accuracy of the lateral distance between the clamping parts, greatly improving the work efficiency, and saving the work cost.

[0029] In order to achieve accurate positioning of the foam damping sheet 2 by the pressing member in the longitudinal direction and prevent the pressing member from being offset during movement, Figure 5 and Figure 6As shown, in this embodiment, guide grooves 12a of preset depth are provided on both sides of the fixed plate 7, and moving blocks 51a matching the guide grooves 12a are provided under the first support plate 3b and the fourth support plate 6b, and second protrusions 42a are provided on one side of the first sliding block 3a and the fourth sliding block 6a, and matching hollow grooves are provided on the first moving rod 11 and the second moving rod 12, so as to limit multiple degrees of freedom of the clamping mechanism and increase the stability of the movement. At this time, under the push and pull of the electric cylinder, the first clamping mechanism 3 and the fourth clamping mechanism 6 are respectively moved linearly relative to the second clamping mechanism 4 and the third clamping mechanism 5, thereby improving the accuracy of the longitudinal distance positioning of the foam shock absorbing plate 2 and greatly improving the stability of the work.

[0030] In order to solve the problem that the moving rod is easy to be damaged and inconvenient to replace during the subsequent long-term use, such as Figure 2 and Figure 3 As shown, in this embodiment, a first connecting block 10c and a second connecting block 10d are respectively connected to one side of the first push rod 10a and the second push rod 10b, and the first connecting block 10c and the second connecting block 10d at one end away from the first push rod 10a and the second push rod 10b are set to a hollow "T" shape, and the first moving rod 11 and the second moving rod 12 connected thereto are set to a cylindrical "T" shape corresponding to the "T" shape at the connection point, which is engaged in the hollow groove of the connecting block and then fixed with screws. On the one hand, the stability of the moving rod connection is increased, and secondly, setting the connecting block to a hollow shape can also save some materials. When the moving rod is damaged, the moving rod can be quickly taken out and a new moving rod can be engaged in the connecting block, which further improves work efficiency and saves work costs.

[0031] In the process of positioning the foam shock-absorbing sheet 2, the irregular shape of the pressing piece is prevented, and the foam shock-absorbing sheet 2 is not worn or damaged during the pressing process. In this embodiment, the first pressing piece 3d, the second pressing piece 4d, the third pressing piece 5d and the fourth pressing piece 6d are "L" shaped and have rounded corners. On the one hand, the foam shock-absorbing sheet 2 can be pressed flatly, and on the other hand, it will not be worn due to the edges and corners, which further improves the stability of the work, greatly improves the work efficiency, saves work time, and reduces work costs.

[0032] As described above, although the present invention has been represented and described with reference to specific preferred embodiments, it should not be interpreted as a limitation of the present invention itself, and various changes in form and details may be made without departing from the spirit and scope of the present invention defined in the appended claims.
