DETAILED DESCRIPTION
[0019] The present invention will be described in detail below with reference to the accompanying drawings and through examples. The following examples are intended to explain the present invention, but the present invention is not limited to the following examples.
[0020] See also Figure 1-4 The present embodiment relates to a hot melt adhesive cutting device, comprising a frame 101, a cutting table 102 arranged thereon, and a cutting machine body 100 formed by a cutting knife group 1 connected to the cutting table 102 via a multi-axis structure 103. The cutting knife group 1 comprises a fixed seat 11 and a knife seat 12 mounted thereon, a knife head 13 and a support assembly 2 mounted on the knife seat 12 via a connecting seat 14. The support assembly 2 comprises a plurality of support rods 21 slidably arranged on the connecting seat 14 and arranged around the periphery of the knife head 13, a plurality of compression springs 22 adaptively arranged on the outer sides thereof, and a plurality of balls 23 rotatably arranged at the bottom of the support rods 21.
[0021] Specifically in this embodiment, Figure 1 The overall structure of the hot melt adhesive cutting device shown in the figure can be seen in the following figure. Figure 2 As shown, the cutting blade assembly 1 is connected to the cutting table 102 via a multi-axis structure 103 installed on the frame 101 at a position corresponding to the cutting table 102. The multi-axis structure 103 is configured as follows: Figure 1 or Figure 2 The commonly used synchronous belt slide structure is shown in the figure, and the cutting knife group 1 is moved in the corresponding direction of the cutting table 102 by a plurality of driving components 1031 driven by synchronous belts provided on the corresponding positions of the cutting table 102. The specific structure of the cutting knife group 1 can be seen in Figure 3 As shown, the cutting knife group 1 is connected and fixed with the multi-axis structure 103 provided on the corresponding position of the frame 101 through the fixed seat 11 provided thereon. Figure 4As shown, the cutter head 13 installed on the cutter seat 12 is controlled by the multi-axis structure 103 to contact the hot melt adhesive coating surface pressed on the cutting table 102. At the same time, the support assembly 2 provided on the cutter seat 12 moves synchronously, and the multiple groups of support rods 21 slidingly provided on the connecting seat 14 can pre-contact the hot melt adhesive coating surface through the bottom ball 23. Specifically, the initial position of the bottom ball 23 of the support rod 21 is set and installed lower than the bottom of the cutter head 13 on the cutter seat 12. Therefore, during the contact process between the cutter head 13 and the hot melt adhesive coating surface, the support rod 21 is subjected to a certain pressure and can slide in the corresponding direction along the through hole 141 opened at the corresponding position of the connecting seat 14 through the compression spring 22 provided on the outside.
