Description

Technical Field

[0001] The utility model relates to the technical field of powder processing equipment, in particular to a super washable copolyester hot melt adhesive powder processing device. Background Art

[0002] Hot melt adhesive is an important industrial adhesive with very high viscosity. This includes copolyester hot melt adhesive powder obtained by grinding hot melt adhesive particles. Due to its high strength, high viscosity, high heat resistance and water resistance, it is in powder form after production. Powdered hot melt adhesive is easier to mix with other materials, improves the bonding effect, and is also easier to store.

[0003] However, when the existing super-strong water-resistant copolyester hot-melt adhesive powder processing equipment grinds the copolyester hot-melt adhesive particles into powder, the grinding tool in the grinding equipment needs to be in contact and friction with the hot-melt adhesive particles for a long time, which causes the temperature of the grinding tool surface to rise relatively high, especially in a closed grinding chamber, and the cooling rate is relatively slow, resulting in the copolyester hot-melt adhesive powder being more likely to change in physical properties due to the high temperature on the grinding tool surface; in addition, when the existing hot-melt adhesive powder equipment discharges the ground powder, the discharge port of the equipment is usually aligned with the top of the open container without being sealed, which makes it easy for dust to fly when the hot-melt adhesive powder falls into the open container, which is not conducive to the discharge of the hot-melt adhesive powder. Utility Model Content

[0004] The purpose of the utility model is to provide a super washable copolyester hot melt adhesive powder processing device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a super-strong water-resistant copolyester hot melt adhesive powder processing equipment, comprising a vertical box, a feed hopper passing through the top of the vertical box, a grinding chamber opened at the top inside the vertical box, a grinding tool provided inside the grinding chamber, a spiral tube embedded inside the grinding tool, a connecting pipe provided on one side of the grinding tool, a return pipe provided on the other side of the grinding tool, a movable block provided at the bottom of the grinding chamber, a discharge box provided at the bottom of the movable block, a tipping bucket provided at the top of the discharge box, a bottom box fixedly connected to the back of the vertical box, the interior of the bottom box is filled with coolant through the opened cavity, a water inlet pipe and a water outlet pipe respectively passed through one side wall of the bottom box, a refrigeration mechanism is installed at the bottom of the cavity inside the bottom box, and a water pump is fixedly installed on the top of the bottom box.

[0006] Preferably, the connecting pipe and the return pipe are movably connected to the two ends of the spiral pipe through a mold and a rotary joint respectively, the end of the connecting pipe away from the mold is engaged with the outlet pipe, and the bottom end of the return pipe passes through the top of the bottom box.

[0007] Preferably, the water outlet pipe is snap-connected with the output end of the water pump, and the input end of the water pump is communicated with the interior of the bottom box.

[0008] Preferably, both ends of the spiral tube protrude from the two side walls of the mold, a first gear is engaged with the outer wall of the spiral tube close to one end of the bottom box, and a second gear is meshed with the outer wall of the first gear.

[0009] Preferably, a rotating motor is fixedly mounted on the top of the bottom box, and an output end of the rotating motor is engaged with the second gear.

[0010] Preferably, an electric push rod is fixedly mounted on one side wall of the vertical box, the output end of the electric push rod is engaged and connected with the movable block, and the movable block is movably connected to the grinding chamber through the electric push rod.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] This super-strong water-resistant copolyester hot-melt adhesive powder processing equipment uses a water outlet pipe, a spiral pipe, a return pipe, a connecting pipe and a coolant, so that when the abrasive tool in the processing equipment is grinding hot-melt adhesive particles, the heat generated by friction on the surface can be carried away by the circulating coolant, so that the temperature of the abrasive tool surface will not rise due to continuous friction, and the surface temperature can be kept in a relatively low temperature environment, thereby reducing the probability of the physical properties of the hot-melt adhesive powder being changed due to the high temperature of the abrasive tool surface.

[0014] This super-strong water-resistant copolyester hot melt adhesive powder processing equipment uses a discharge box, a tipping bucket and a movable block to allow the ground hot melt adhesive powder to fall from the inside of the grinding chamber into the discharge box in a relatively closed environment. At the same time, when falling into the discharge box, it can be secondary isolated through the tipping bucket, so that the powder falling into the discharge box is not easy to float out from the inside of the discharge box when flying, which is more conducive to the discharge of the hot melt adhesive powder.

[0024] like Figures 1 to 5As shown, the super washable copolyester hot melt adhesive powder processing equipment of this embodiment includes a vertical box 2, which is a fixedly connected structure with the bottom box 7. The top of the vertical box 2 is penetrated by a feed hopper 1, and the interior of the feed hopper 1 is communicated with the interior of the grinding chamber 14. The top of the inner side of the vertical box 2 is provided with a grinding chamber 14, and the interior of the grinding chamber 14 is provided with a grinding tool 15. The inner wall of the grinding chamber 14 and the outer wall of the grinding tool 15 are fixedly connected with a plurality of grinding teeth, so that the copolyester hot melt adhesive particles can be smoothly ground in the equipment. The interior of the grinding tool 15 is embedded with a spiral tube 16, and the spiral tube 16 is distributed near the outer wall of the grinding tool 15. On the other side of the mold 15, a return pipe 10 is provided. The function of the return pipe 10 is to allow the coolant 22 that has absorbed the heat to return to the bottom box 7 for re-cooling and wait for subsequent recycling. The bottom of the grinding chamber 14 is provided with a connecting pipe 3. The function of the connecting pipe 3 is to allow the coolant 22 in the bottom box 7 to pass smoothly from the middle of the mold 15 into the spiral pipe 16 of the mold 15, thereby achieving the cooling of the outer wall of the mold 15 by the coolant 22. A movable block 17 is provided, and a discharge port is provided at the junction of the bottom of the grinding chamber 14 and the movable block 17. When the movable block 17 is moved away, the hot melt adhesive powder that has been ground will fall from the discharge port into the tipping bucket 19 below. A discharge box 4 is provided at the bottom of the movable block 17, and the top of the discharge box 4 is open. The function is to collect the falling hot melt adhesive powder so that the hot melt adhesive powder can be kept in a relatively closed environment during discharge, which is more conducive to the discharge of the hot melt adhesive powder. A tipping bucket 19 is provided on the top of the discharge box 4. The surface of the tipping bucket 19 is smooth and not easy to adhere to the hot melt adhesive powder. The back of the vertical box 2 is fixedly connected to the bottom Box 7, the interior of the bottom box 7 is filled with coolant 22 through the opened cavity, and a water inlet pipe 6 and a water outlet pipe 5 are respectively passed through one side wall of the bottom box 7. The function of the water inlet pipe 6 is to replenish the coolant 22 consumed by heat into the bottom box 7, so that the equipment has enough coolant 22 to maintain the cooling of the mold 15. A refrigeration mechanism 21 is installed at the bottom of the inner cavity of the bottom box 7. The refrigeration mechanism 21 enables the coolant 22 flowing back into the bottom box 7 to be quickly cooled, thereby facilitating the continuous circulation of the coolant 22. A water pump 20 is fixedly installed on the top of the bottom box 7, so that the coolant 22 can circulate in the equipment.

[0025] Specifically, the connecting pipe 3 and the return pipe 10 are movably connected to the two ends of the spiral tube 16 through the mold 15 and the rotary joint 9 respectively. The end of the connecting pipe 3 away from the mold 15 is engaged with the outlet pipe 5, and the bottom end of the return pipe 10 passes through the top of the bottom box 7. The connecting pipe 3 can deliver the coolant 22 into the spiral tube 16, and the return pipe 10 can return the coolant 22 that has absorbed heat to the bottom box 7 for subsequent recycling, thereby realizing the circulation of the coolant 22 in the equipment.

[0026] Furthermore, the water outlet pipe 5 is snap-connected with the output end of the water pump 20, and the input end of the water pump 20 is communicated with the interior of the bottom box 7. The water pump 20 can allow the coolant 22 to circulate in the spiral tube 16, thereby helping to keep the outer wall of the mold 15 in a relatively low temperature environment and reduce the probability of changes in the physical properties of the hot melt adhesive powder due to the high temperature of the mold 15.

[0027] Furthermore, both ends of the spiral tube 16 protrude from the two side walls of the grinding tool 15, and the outer wall of the spiral tube 16 close to the end of the bottom box 7 is engaged with the first gear 8, and the outer wall of the first gear 8 is engaged with the second gear 11. The second gear 11 engages with the first gear 8 and rotates to enable the grinding tool 15 to rotate in the grinding chamber 14, thereby providing power for the rotation of the grinding tool 15.

[0028] Furthermore, a rotary motor 12 is fixedly mounted on the top of the bottom box 7 , and an output end of the rotary motor 12 is engaged with the second gear 11 . When energized, the rotary motor 12 can drive the second gear 11 to rotate, providing power for the rotation of the second gear 11 .

[0029] Furthermore, an electric push rod 13 is fixedly installed on one side wall of the vertical box 2, and the output end of the electric push rod 13 is engaged with the movable block 17. The movable block 17 is movably connected to the grinding chamber 14 through the electric push rod 13. When the electric push rod 13 is energized, it can drive the movable block 17 to move at the bottom of the grinding chamber 14, thereby realizing the opening and closing of the discharge port at the bottom of the grinding chamber 14.

[0030] Furthermore, a card strip 18 is engaged with the top of the inner side of the discharge box 4, and the bucket 19 is movably connected to the card strip 18. The discharge box 4 is movably embedded in the vertical box 2. The card strip 18 enables the bucket 19 to be erected inside the discharge box 4, and at the same time facilitates the removal of the bucket 19 from the discharge box 4, thereby facilitating the removal of the hot melt adhesive powder from the discharge box 4.

[0031] The method of using this embodiment is as follows: when using this super strong water-resistant copolyester hot melt adhesive powder processing equipment, it is necessary to first connect the equipment to an external power supply, then add coolant 22 to the water inlet pipe 6, then the water pump 20 pumps the coolant 22 from the water outlet pipe 5 into the connecting pipe 3, and then enters the spiral tube 16 of the mold 15 through the connecting pipe 3, and then the coolant 22 enters the return pipe 10 from the end of the spiral tube 16, so that the coolant 22 returns to the bottom box 7 and is cooled by the cooling mechanism. At this time, the rotating motor 12 is started, so that the rotating motor 12 drives the second gear 11 to rotate, so that the second gear 11 engages with the first gear 8 to rotate, driving the mold 15 to rotate in the grinding chamber 14, and then the copolyester hot melt glue particles can be poured from the feed hopper 1, so that the glue particles fall into the grinding chamber 14 for grinding, and the continuously flowing coolant 22 in the spiral tube 16 will keep the surface of the mold 15 in a relatively low temperature environment, and then the hot melt glue powder that has been ground will fall to the bottom of the active grinding chamber 14, and then the electric push rod 13 is started to move the movable block 17 away from the bottom of the grinding chamber 14, and the hot melt glue powder will fall into the tipping bucket 19 through the opened discharge port, and then slide along the tipping bucket 19 into the discharge box 4 to be collected.

[0032] 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.
