DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-3 This application is described in further detail.

[0023] The embodiment of the present application discloses a sporadic barrel heating device.

[0024] Reference Figure 1 and Figure 2 The sporadic barrel heating device includes a barrel body 1 for containing glue, a heat conducting plate 2 is fixedly connected to the outer peripheral wall of the barrel body 1, and the heat conducting plate 2 is spirally wound on the outer peripheral wall of the barrel body 1, and the heat conducting plate 2 can be made of metal; a limiting groove 4 is provided on the surface of the heat conducting plate 2 away from the barrel body 1, and the limiting groove 4 is also spirally arranged, and a heating wire 3 matching the limiting groove 4 is tightly arranged in the limiting groove 4, and the heating wire 3 in the limiting groove 4 is also spirally wound on the outer edge of the barrel body 1; the limiting groove 4 has the function of supporting and limiting the heating wire 3, so that the heating wire 3 is not easy to be offset and misaligned relative to the heat conducting plate 2 under the action of external force. Therefore, when the outside temperature is low, the staff can use the heating wire 3 to heat the heat conducting plate 2, and the heat on the heat conducting plate 2 can pass through the barrel body 1 to heat the glue inside the barrel body 1, thereby reducing the decrease in fluidity of the glue inside the barrel body 1 due to the decrease in temperature, thereby improving the performance of the glue.

[0025] Reference Figure 1 and Figure 2 , the outer edge of the barrel body 1 is wrapped with a ring-shaped first thermal insulation cotton 5, the heat conducting plate 2 and the electric heating wire 3 are both located at the inner edge of the first thermal insulation cotton 5, and the first thermal insulation cotton 5 is detachably connected to the heat conducting plate 2. The setting of the first thermal insulation cotton 5 has the effect of heat preservation and heat insulation, thereby further improving the heating effect of the electric heating wire 3 on the glue inside the barrel body 1. The setting of the first thermal insulation cotton 5 and the heat conducting plate 2 being detachably connected to each other allows the staff to flexibly adjust the thermal insulation state of the barrel body 1 according to actual conditions; for example, when the outside temperature is low and the glue in the barrel body 1 needs to be heated and insulated, the first thermal insulation cotton 5 is installed and wrapped on the outer edge of the barrel body 1 for insulation; when the outside temperature is high, the first thermal insulation cotton 5 can be removed from the barrel body 1; at the same time, the detachable setting of the first thermal insulation cotton 5 also facilitates the staff to regularly replace the damaged first thermal insulation cotton 5.

[0026] Reference Figure 2, a plurality of connecting bolts 6 are provided on the first heat-insulating cotton 5, and a plurality of connecting grooves 7 matching the connecting bolts 6 are correspondingly provided on the end surface of the heat-conducting plate 2 away from the barrel body 1, and the first heat-insulating cotton 5 is detachably connected to the heat-conducting plate 2 by means of a plurality of connecting bolts 6 being threadedly connected in a plurality of connecting grooves 7 respectively; when the first heat-insulating cotton 5 is connected to the outer edge of the barrel body 1, the first heat-insulating cotton 5 is tightly pressed between the ends of the plurality of connecting bolts 6 and the heat-conducting plate 2. Therefore, the staff can install or remove the first heat-insulating cotton 5 by means of bolt disassembly according to actual needs, so that the staff can flexibly adjust the heat-insulating state of the barrel body 1 or replace the first heat-insulating cotton 5 according to actual conditions.

[0027] Reference Figure 2 In order to further improve the stability of the connection between the first thermal insulation cotton 5 and the barrel body 1, a support ring 8 is sleeved on the outer edge of the connecting bolt 6; when the first thermal insulation cotton 5 is connected to the outer edge of the barrel body 1, the support ring 8 is pressed between the end of the connecting bolt 6 and the first thermal insulation cotton 5. The provision of the support ring 8 increases the contact area between the end of the connecting bolt 6 and the first thermal insulation cotton 5, so that the pressing force from the connecting bolt 6 can be evenly dispersed on the first thermal insulation cotton 5 through the support ring 8, thereby further strengthening the connection stability between the first thermal insulation cotton 5 and the barrel body 1.

[0028] Reference Figure 1 and Figure 3 The bottom of the barrel body 1 is fixedly connected with a support frame 9, and the bottom of the support frame 9 is connected with a plurality of universal wheels 11, and the staff can conveniently adjust the position of the barrel body 1 through the universal wheels 11; the bottom surface of the barrel body 1 is bonded with a second thermal insulation cotton 10, and the outer edge of the second thermal insulation cotton 10 is in contact with the first thermal insulation cotton 5. Therefore, the provision of the second thermal insulation cotton 10 reduces the possibility of the heat in the barrel body 1 being quickly dissipated from the bottom of the barrel body 1, thereby further improving the thermal insulation performance of the barrel body 1.

[0029] Reference Figure 1 and Figure 3In order to improve the stability of the barrel body 1, two brake frames 12 are fixedly connected to the support frame 9, and the barrel body 1 is located between the two brake frames 12. Brake rods 13 are respectively penetrated and threadedly connected on the two brake frames 12 in the vertical direction. The ends of the brake rods 13 located at the bottom are rotatably connected to brake plates 14 arranged in the horizontal direction. The ends of the brake rods 13 away from the brake plates 14 are fixedly sleeved with handwheels 15. A rubber plate 16 is connected to the end surface of the brake plates 14 facing away from the brake rods 13. A plurality of anti-skid ridges 17 are provided on the surface of the rubber plates 16 facing away from the brake plates 14. The plurality of anti-skid ridges 17 are integrally formed with the rubber plates 16. Therefore, after the barrel body 1 is moved to the target position, the staff can drive the brake rod 13 by turning the hand wheel 15 to drive the brake plate 14 and the rubber plate 16 to move downward until the anti-slip ridges 17 on the rubber plate 16 are tightly against the ground, thereby fixing the position of the barrel body 1; reducing the possibility that the barrel body 1 will move and deviate from the target position under the action of external force after being pushed to the target position, thereby further improving the stability of the barrel body 1.

[0030] Reference Figure 3 In order to facilitate the replacement of the aged or damaged rubber sheet 16, a plurality of mounting bolts 18 are provided on the rubber sheet 16, and the plurality of mounting bolts 18 and the plurality of anti-skid ridges 17 are mutually staggered, and the rubber sheet 16 is detachably connected to the brake plate 14 by bolting the plurality of mounting bolts 18 to the brake plate 14. Therefore, the staff can regularly remove the rubber sheet 16 from the brake plate 14 by bolt removal, and then conveniently replace the damaged or aged rubber sheet 16.

[0031] The implementation principle of the embodiment of the present application is: when the outside temperature is low, the staff can install the first thermal insulation cotton 5 to the outer edge of the barrel body 1, and then use the heating wire 3 to heat the inside of the barrel body 1, thereby reducing the fluidity of the glue inside the barrel body 1 due to the decrease in temperature, thereby improving the performance of the glue; when the outside temperature is high, the staff can remove the first thermal insulation cotton 5 from the barrel body 1 so that the heat inside the barrel body 1 can be quickly dissipated, that is, the thermal insulation performance of the barrel body 1 can be flexibly adjusted according to actual conditions.
