[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-6As shown, the utility model provides a technical solution: a hot melt adhesive filtering device of a glue machine, comprising a glue box 1, a threaded connection seat 2 arranged on the surface of the glue box 1, a plug 3 threadedly connected to the threaded connection seat 2, and a glue outlet pipe 4 on the glue box 1 corresponding to the position of the plug 3, one end of the plug 3 is equidistantly and vertically fixedly connected with a plurality of connecting plates 5 along the circumferential direction, the sum of the thickness of the connecting plate 5 and the spliced ​​filter screen 10 is the same as the wall thickness of the connecting pipe 6, the connecting pipe 6 entering the glue box 1 and the spliced ​​filter screen 10 form a structure with the same thickness throughout, and insertion is more convenient;

[0022] The ends of the multiple connecting plates 5 away from the plug 3 are fixedly connected to a connecting tube 6 connected to the glue outlet pipe 4. The inner diameter of the glue outlet corresponding to the connecting tube 6 and the glue outlet pipe 4 is smaller than the radius of the ball 9. The connecting tube 6 and the ball 9 are in clearance fit. Under the pressure of the end frame 401, the ball 9 retracts into the connecting tube 6, and the filtered hot melt adhesive in the connecting tube 6 flows out through the gap between the ball 9 and the connecting tube 6.

[0023] A retaining frame 7 is fixedly installed in the connecting pipe 6, and a supporting spring 8 is arranged on one side of the retaining frame 7. One side of the supporting spring 8 supports a ball 9 that contacts the upper end frame 401 of the rubber outlet pipe 4. A plurality of connecting plates 5 are provided with a plurality of spliced ​​filter screens 10 located between the plug 3 and the connecting pipe 6. The spliced ​​filter screen 10 includes a plurality of independent arc filter screen plates and is connected to the connecting plate 5 by countersunk hexagon socket bolts 11, ensuring that the radius of the spliced ​​filter screen 10 is the same as the radius of the connecting pipe 6, and will not affect the normal insertion of the connecting pipe 6.

[0024] Working principle:

[0025] The cold glue in the glue box 1 flows through the spliced ​​filter screen 10 and the connecting pipe 6 into the glue outlet pipe 4 and flows out. The support spring 8 contracts when the end frame 401 on the glue outlet pipe 4 squeezes the ball 9, and the ball 9 is separated from the glue outlet port of the connecting pipe 6, providing a channel for the cold glue to flow. When it needs to be disassembled and cleaned, the plug 3 is directly twisted to remove the plug 3, the connecting plate 5, the connecting pipe 6 and the spliced ​​filter screen 10 from the glue box 1 and the threaded connection seat 2. When the support spring 8 loses the end frame 401 on the glue outlet pipe 4 to squeeze the ball 9, the ball 9 is pushed to dock with the glue outlet of the connecting pipe 6 to prevent external dust and debris from entering the connecting pipe 6 and the inner side of the spliced ​​filter screen 10. The spliced ​​filter screen 10 can be disassembled, cleaned and replaced separately, and the plug 3 is also very convenient to disassemble, thereby simplifying the cleaning process of the filtering device.
