Description

Technical Field

[0001] The utility model relates to the technical field of adhesive melting devices, in particular to an acrylic pressure-sensitive adhesive melting device for ultra-low temperature use. Background Art

[0002] Acrylic pressure-sensitive adhesive has good low-temperature and high-temperature resistance, low condensable volatiles and mass loss rate, and no harmful gas escape. It is used to make various types of pressure-sensitive tapes. Pressure-sensitive adhesive generally exists in solid form and can be prepared into granular, cylindrical and block shapes according to needs. When used, it is melted by high-temperature heating to make it liquid. The pressure-sensitive adhesive is applied to the object to be bonded or the tape by spraying or coating. After forming, the pressure-sensitive adhesive will cool rapidly under suitable environmental conditions to form a high-strength adhesive layer.

[0003] At present, the glue melting devices are generally hot melt glue guns and hot melt glue pens. When in use, the device uses internal heating components to perform hot melt processing on the pressure-sensitive adhesive. The melted pressure-sensitive adhesive is sprayed out through the glue nozzle and then coated on the corresponding object or tape. However, pressure-sensitive adhesive sometimes needs to be used in a low-temperature environment. At this time, the glue liquid at the glue nozzle is easy to solidify, which in turn affects the normal glue discharge of the equipment. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides an ultra-low temperature acrylic pressure-sensitive adhesive melting device. By arranging a heat-insulating cap on the glue outlet pipe, the electric heating plate arranged inside it can insulate the environment at the glue outlet nozzle, avoiding the situation where the temperature is too cold and the glue is quickly solidified, resulting in the inability to discharge glue normally. This solves the problem that the glue liquid at the glue outlet nozzle of the current glue melting equipment is easily solidified.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example

[0023] like Figure 1 、 Figure 2 and Figure 3 As shown, an embodiment of the present invention proposes an ultra-low temperature acrylic pressure-sensitive adhesive melting device, which includes a barrel 1, a heating part 4 is provided on one side of the barrel 1, and a glue outlet pipe 5 is connected to a conical connecting part 8 provided on the other side of the heating part 4, and the glue outlet pipe 5 is connected to a glue outlet nozzle 7, and an insulating cap 6 is provided on the glue outlet pipe 5, and the insulating cap 6 includes: an annular body 601, the annular body 601 is adapted to be on the glue outlet pipe 5: a groove 603, which is formed on the inner side of the annular body 601, and an insulating cover 608 is fixedly connected to the groove 603 of the annular body 601, and an electric heating plate 609 is installed on the inner side of the insulating cover 608, and the electric heating plate 609 can form an insulation treatment at the glue outlet nozzle 7 when energized to prevent the glue liquid from solidifying.

[0024] It should be noted that a glue stick channel is formed on the inner side of the barrel 1 for storing glue sticks. By arranging a heating portion 4 on one side of the barrel 1, the end of the glue stick is heated to form glue liquid. By arranging a glue discharge pipe 5 on the conical connecting portion 8 on one side of the heating portion 4, and connecting the glue discharge nozzle 7 on the glue discharge pipe 5, the glue liquid can be discharged through the glue discharge pipe 5 and the glue discharge nozzle 7, and then the glue liquid can be applied to the corresponding adhesive tape or object. By arranging a heat-insulating cap 6 on the glue discharge pipe 5, the heat-insulating cap 6 can achieve heat preservation treatment at the glue discharge nozzle 7 to avoid In a cold environment, the glue at the glue nozzle 7 solidifies (the glue melting equipment is not working), which leads to the subsequent inability to use normally. When glue needs to be applied, the thermal insulation cap 6 can be removed. The thermal insulation cap 6 includes a ring body 601, a groove 603, an insulating cover 608 and a heating plate 609. The insulating cover 608 realizes the installation of the heating plate 609. The heating plate 609 can form an insulation treatment at the glue nozzle 7 when power is turned on to prevent the glue from solidifying (it can be used without applying glue, and the thermal insulation cap 6 can be removed when glue application is required).

[0025] like Figure 2 As shown, in some embodiments, a lithium battery 605 is installed on a battery slot 604 opened on one side of the ring body 601, and a switch 602 is provided on the ring body 601, and the switch 602, the lithium battery 605 and the electric heater 609 are connected in series.

[0026] It should be noted that the lithium battery 605 is used to power the electric heater 609, and the switch 602 is used to control the heating and heat preservation state.

[0027] like Figure 2 As shown, in some embodiments, an annular protrusion 607 is protruded from one side of the annular body 601 close to the battery slot 604 , and a protective cap 606 is threadedly connected to the annular protrusion 607 .

[0028] It should be noted that the protective cap 606 is detachably assembled on the annular body 601 , thereby facilitating the replacement of the lithium battery 605 .

[0029] like Figure 1 As shown, in some embodiments, an arc-shaped cavity 10 is opened on the cylinder body 1, and an arc-shaped cover 2 is rotatably connected to the arc-shaped cavity 10 of the cylinder body 1, and a locking tongue 3 is installed on one side of the arc-shaped cover 2, and the locking tongue 3 is adapted to the corresponding lock hole 9 on the cylinder body 1.

[0030] It should be noted that by providing an arc-shaped cavity 10 on the barrel body 1, it is convenient to load the glue stick. By rotating the arc-shaped cover 2 at the arc-shaped cavity 10 of the barrel body 1, the arc-shaped cover 2 can achieve a protective effect at the arc-shaped cavity 10. By installing a lock tongue 3 on the arc-shaped cover 2, the lock tongue 3 is adapted to the corresponding lock hole 9 on the barrel body 1 to achieve the fixation of the arc-shaped cover 2 on the barrel body 1. This method facilitates the assembly of the glue stick and is convenient.

[0031] like Figure 1 As shown, in some embodiments, a feeding component is also included, which includes: a screw 12, which is threadedly connected to one side of the barrel 1; a push plate 11, which is adapted on the inner side of the barrel 1, and one side of the push plate 11 is coaxially connected to one end of the screw 12 for rotation; and a handwheel 13, which is fixedly connected to the other end of the screw 12.

[0032] It should be noted that the arrangement of the push plate 11, the screw 12 and the hand wheel 13 facilitates the feeding of the glue stick. When in use, the screw 12 is rotated by the hand wheel 13, and then the push plate 11 moves, and the push plate 11 pushes the glue stick to realize the feeding of the glue stick. The push plate 11 is coaxially connected to the screw 12. When the screw 12 rotates, the push plate 11 does not rotate, thereby realizing stable feeding of the glue stick.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
