Description

Technical Field

[0001] The utility model relates to a hot melt adhesive compound machine with a drying structure, belonging to the technical field of hot melt adhesive compound machines. Background Art

[0002] In the processing and production of composite fabrics, the connection between fabrics or between fabrics and membranes is mainly processed by hot melt adhesive laminating machines.

[0003] However, existing hot melt adhesive laminating machines generally do not have a drying structure. When laminating some thinner fabrics, they are often rolled up without being dried in time after lamination, resulting in glue overflow and sticking on the surface of the composite fabric when the composite fabric is used subsequently, affecting the normal use of the composite fabric. In view of the above shortcomings, the utility model proposes a hot melt adhesive laminating machine with a drying structure. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a hot melt adhesive compounding machine with a drying structure to solve the existing problems.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized by the following technical scheme: a hot melt adhesive compound machine with a drying structure, comprising a frame, a material rack arranged on the frame from left to right, a first supporting roller, a compounding roller, a second supporting roller, a drying device, a third supporting roller and a reel, the drying device comprising a drying box, a first drying plate group arranged at the lower end of the drying box cavity, and a second drying plate group is vertically symmetrically arranged above the top surface of the first drying plate group, and a hair dryer is connected between the first drying plate group and the second drying plate group through an air inlet hose;

[0006] The first drying plate group includes a heating base plate, a blowing top plate attached to the top surface of the heating base plate, a supporting roller group arranged at intervals in the cavity of the blowing top plate, and a plurality of heating tubes arranged at intervals in the cavity of the heating base plate. A blowing tube box is connected to the rear end side of the heating base plate, and an air inlet tube is connected to one side of the blowing tube box. The first drying plate group has the same structure as the second drying plate group, but there is no supporting roller group on the second drying plate group.

[0007] As a further improvement, a door for feeding composite materials is hingedly connected to the rear side of the drying box, a material inlet is provided on the left side of the drying box, and a material outlet is provided on the right side of the drying box.

[0008] As a further improvement, a heating tube groove for installing each heating tube is provided on the top surface of the heating bottom plate, and a plurality of air inlet openings connected to the blowing tube box are provided at intervals on the groove wall at the rear side of the heating tube groove.

[0009] As a further improvement, a plurality of blowing openings connected to the heating tube grooves are provided at intervals on the blowing top plate, and each blowing opening is vertically aligned with each heating tube in a one-to-one correspondence.

[0010] As a further improvement, the composite roller and the winder are prior art, and their structures are not described in detail here.

[0011] The beneficial effects of the utility model are:

[0012] The utility model provides a hot melt adhesive compounding machine with a drying structure. The drying device composed of a drying box, a first drying plate group, a second drying plate group and a hair dryer is designed as a structural combination on the right side of a compounding roller on the compounding machine. After the fabric is compounded with the hot melt adhesive and conveyed to the right, it is promptly dried by double-sided hot air blowing in the drying device, so that the hot melt adhesive in the compounded fabric is accelerated to solidify, and the fabric will not overflow and stick to the surface of the fabric due to the unsolidified hot melt adhesive after being wound up by the winder at the rightmost end of the compounding machine, thereby improving the compounding quality.

The first drying plate group 62 has the same structure as the second drying plate group 63, but the second drying plate group 63 does not have a supporting roller group 623. A door 611 for threading composite materials is hingedly connected to the rear side of the drying box 61. A feed inlet 612 is provided on the left side of the drying box 61, and a discharge outlet 613 is provided on the right side of the drying box 61. A heating pipe groove 6211 for installing each heating pipe 624 is provided on the top surface of the heating bottom plate 621, and a plurality of air inlet openings 6212 connected to the blow pipe box 625 are spaced apart on the rear side groove wall of the heating pipe groove 6211. A plurality of blowing openings 6221 connected to the heating pipe groove 6211 are spaced apart on the blowing top plate 622, and each blowing opening 6221 is vertically aligned with each heating pipe 624 in a one-to-one correspondence.

[0018] Working principle:

[0019] When in use, after the fabric is compounded with hot melt adhesive by the compounding roller 4 from the left side and transported to the right, when passing through the drying device 6, the fabric at this time is transported by the bottom surface of the fabric against the top surfaces of multiple rollers of the supporting roller group 623 under the action of the second supporting roller 5 and the third supporting roller 7. In this process, the air inlet hose of the blower 64 blows air synchronously to the first drying plate group 62 and the second drying plate group 63, and the gas enters the blowing pipe box 625 through the air inlet pipe 626 and is discharged from each air inlet port 6212. The hot air is blown into the heating tube groove 6211, thereby taking away the heat generated by each heating tube 624 in the heating tube groove 6211 and blowing upward through each blowing hole 6221. Because the first drying plate group 62 and the second drying plate group 63 are symmetrically arranged, the hot air is blown upward from the first drying plate group 62 and blown downward from the second drying plate group 63, so that the hot air is used to dry the fabric after hot melt adhesive compounding on both sides, so that the hot melt adhesive in the fabric can be cured faster, and finally it is transported to the right and rolled up by the winder 8.
