Description

Technical Field

[0001] The invention relates to the technical field of hot-melting of new materials, in particular to a hot-melting device for producing new materials. Background Art

[0002] The hot melt machine uses electric heating to transfer heat from the heating plate to the corresponding material structure. In the production process of new materials, it is usually necessary to heat the new materials to a molten state and then pour them out to complete the collection or corresponding casting process. During this process, the hot melt device needs to complete the new material feeding, melting and pouring processes.

[0003] However, in the traditional technology, direct cylinder drive is used to control the rotation of the hot melt box. However, since the interior of the hot melt box is filled with a lot of molten material, its weight is usually high, and as the liquid level continues to change during the pouring process, the center of gravity of the hot melt box also changes continuously. Relying solely on the control of the driving cylinder leads to a high initial driving force requirement, and the driving force during the process also needs to be continuously adjusted as the center of gravity changes. The repeated adjustment process thus affects the service life of the equipment.

[0004] At the same time, since there are many types of new materials and the weights of different new materials are inconsistent, the required counterweight weights are also inconsistent. However, if a simple counterweight structure is used, it is impossible to replace the corresponding counterweight weights according to different new materials. Moreover, in the process of adjusting the counterweight structure on both sides, only manually replacing the counterweight discs will easily cause the number of counterweight discs on both sides to be consistent, resulting in inconsistent weights on both sides, affecting the specific counterweight effect. Summary of the invention

[0005] The purpose of the present invention is to solve the existing problems that the initial driving force requirement is high due to the control relying solely on the driving cylinder, and the driving force in the process also needs to be continuously adjusted as the center of gravity changes. The repeated adjustment process thus affects the service life of the equipment. If a simple counterweight structure is used, the corresponding counterweight weight cannot be replaced according to different new materials.

[0018] The invention provides a hot melt device for producing new materials, which has the following beneficial effects:

[0019] Through the cooperation between the hot melt box, the drive motor, the counterweight plate, the drive cylinder, the threaded sleeve block and the inclined beam, before the hot melt box needs to be dumped, the user can control the drive motor so that the output shaft of the drive motor drives the threaded rod to rotate, thereby driving the threaded sleeve block to move outward, so that the threaded sleeve block drives the counterweight plate to move away from the rotating shaft, and increases the force arm on one side of the counterweight plate, so that the weight on both sides of the inclined beam is roughly equal. At this time, starting the drive cylinder again only requires a small force to push the hot melt box to dump, and during the dumping process, the drive motor can control the threaded sleeve block and the counterweight plate inward at any time to achieve the purpose of ensuring that the weight on both sides of the inclined beam is always roughly equal when the liquid level changes. In this way, it is ensured that the drive cylinder only needs a small force to control the dumping process of the hot melt box, effectively avoiding the problem that the initial driving force requirement is high due to relying solely on the control of the drive cylinder, and the driving force in the process also needs to be continuously adjusted as the center of gravity changes, and the repeated adjustment process affects the service life of the equipment.

In this way, the problem of being unable to replace the corresponding counterweight weight according to different new materials if a simple counterweight structure is used is avoided;

[0021] Through the cooperation among the connecting rod, rubber sleeve, spring and pressure plate, when changing the number of counterweight discs, the user can first pull up the connecting rod to make the pressure plate out of the range of threaded rod two, and then put the counterweight disc on the outer wall of threaded rod two, and finally loosen the connecting rod. Once the number of counterweight discs on both sides is inconsistent, a cavity will appear on one side when the pressure plate is pressed down, thus ensuring the consistency of the number of counterweight discs on both sides, effectively avoiding the problem that the number of counterweight discs on both sides is easily inconsistent due to manual replacement of the counterweight discs, resulting in inconsistent weights on both sides that affects the specific counterweight effect.

In this way, it is ensured that the drive cylinder 306 only needs a small force to control the tipping process of the hot melt box 2, effectively avoiding the problem of relying solely on the control of the drive cylinder, which leads to a high initial driving force requirement, and the driving force in the process also needs to be continuously adjusted as the center of gravity changes, and the repeated adjustment process further affects the service life of the equipment.

[0036] See attached Figure 1-6 In this embodiment, the adjustment assembly 5 includes a threaded rod 501, a pressure plate 502, a counterweight plate 503, a counterweight tray 504, a connecting rod 505, a rubber sleeve 506, a spring 507 and a nut 508;

[0037] A plurality of threaded rods 501 are fixedly connected at the center of the upper end of the outer wall of the threaded sleeve block 404, and a counterweight tray 504 is fixedly connected to the lower part of the outer wall of the threaded rod 501. A plurality of counterweight disks 503 are stacked on the upper part of the counterweight tray 504. The upper part of the outer wall of the threaded rod 501 is clearance-matched with the counterweight disk 503 and the pressure plate 502. The pressure plate 502 is used to ensure that the number of counterweight disks 503 on both sides is consistent. The pressure plate 502 is squeezed on the upper surface of the uppermost counterweight disk 503. The uppermost part of the outer wall of the threaded rod 501 is threadedly connected to a nut 508, and the lower surface of the nut 508 is aligned with the pressure plate 502. The upper surfaces are tightly pressed against each other, the outer and inner walls of the outer walls of the front and rear pressure plates 502 are fixedly connected to the connecting rod 505, a rubber sleeve 506 is sleeved at the center of the upper outer wall of the connecting rod 505, and springs 507 are distributed on the outer walls of both sides of the lower part of the connecting rod 505. The elastic coefficient of the spring 507 can be determined according to the specific usage. The ends of the spring 507 are fixedly connected to the pressure plate 502 and the counterweight tray 504 respectively, and the lower ends of both sides of the connecting rod 505 are penetrated and slidably connected to the counterweight tray 504. The positions of the front and rear pressure plates 502 and the number of the counterweight trays 503 are corresponding and consistent;

[0038] Through the cooperation between the nut 508, the second threaded rod 501 and the counterweight plate 503, during the specific use process, the user can also loosen the nut 508 to remove the nut 508 from the upper outer wall of the second threaded rod 501, replace the corresponding number of counterweight plates 503, and then tighten the nut 508. In this way, the problem of being unable to replace the corresponding counterweight weight according to different new materials if a simple counterweight structure is used is avoided;

[0039] Through the cooperation between the connecting rod 505, the rubber sleeve 506, the spring 507 and the pressure plate 502, when changing the number of counterweight discs 503, the user can first pull up the connecting rod 505 to make the pressure plate 502 out of the range of the threaded rod 501, and then put the counterweight disc 503 on the outer wall of the threaded rod 501, and finally loosen the connecting rod 505. Once the number of counterweight discs 503 on both sides is inconsistent, a cavity will appear on one side when the pressure plate 502 is pressed down, thereby ensuring that the number of counterweight discs 503 on both sides is consistent, effectively avoiding the problem that the number of counterweight discs on both sides is easily inconsistent when only manually replacing the counterweight discs, resulting in inconsistent weights on both sides that affects the specific counterweight effect.

[0040] Working principle:

[0041] When the hot melt device for producing new materials is needed, the user can first assemble the overall structure according to the figure. After the assembly is completed, the new material raw material is put into the hot melt box 2 through the material port 6. Then, the heating structure inside the hot melt box 2 is started to heat the new material inside the hot melt box 2 to a molten state. Then, the user can control the driving cylinder 306 to extend the output shaft of the driving cylinder 306, drive the inclined beam 304 to rotate clockwise around the rotating shaft 301, and then the inclined beam 304 can drive the hot melt box 2 to rotate through the main bracket 305. As the angle continues to change, the molten new material inside flows out through the material port 6, and is then dumped into the collection container through the discharge trough 7 and the discharge hopper 8. In this way, the hot melt processing process for producing new materials is completed.

[0042] However, compared with the traditional technology, it adopts direct cylinder drive to control the rotation of the hot melt box. However, since the interior of the hot melt box is filled with a lot of molten material, its weight is usually higher, and with the continuous change of the liquid level during the pouring process, the center of gravity of the hot melt box is also constantly changing. Relying solely on the control of the driving cylinder leads to a higher initial driving force requirement, and the driving force in the process also needs to be constantly adjusted with the change of the center of gravity. The repeated adjustment process further affects the service life of the equipment. Therefore, the present case designs a counterweight assembly 4, so that before the hot melt box 2 needs to be dumped, the user can control the driving motor 401 so that the output shaft of the driving motor 401 drives the threaded rod 405 to rotate, thereby driving the threaded sleeve block 404 to move outward, so that the threaded sleeve block 404 carries The dynamic counterweight plate 503 moves away from the rotating shaft 301, increasing the force arm on one side of the counterweight plate 503, so that the weight on both sides of the inclined beam 304 is roughly equal. At this time, driving the driving cylinder 306 only requires a smaller force to push the hot melt box 2 to tip over. During the tipping process, the driving motor 401 can control the threaded sleeve 404 and the counterweight plate 503 inward at any time to achieve the purpose of ensuring that the weight on both sides of the inclined beam 304 is always roughly equal when the liquid level changes. In this way, it is ensured that the driving cylinder 306 only requires a smaller force to control the tipping process of the hot melt box 2, effectively avoiding the problem that the initial driving force requirement is high due to relying solely on the control of the driving cylinder, and the driving force in the process also needs to be continuously adjusted as the center of gravity changes. The repeated adjustment process further affects the service life of the equipment.

[0043] At the same time, since there are many types of new materials, the weights of different new materials are inconsistent, so the required counterweight weights are also inconsistent. However, if a simple counterweight structure is used, it is impossible to replace the corresponding counterweight weights according to different new materials. Therefore, during specific use, the user can also loosen the nut 508, so that the nut 508 is removed from the upper outer wall of the threaded rod 501, replace the corresponding number of counterweight plates 503, and then tighten the nut 508. In this way, the problem of not being able to replace the corresponding counterweight weights according to different new materials if a simple counterweight structure is used is avoided.

[0044] Moreover, in the process of adjusting the counterweight structure on both sides, only manually replacing the counterweight plates will easily cause the number of counterweight plates on both sides to be consistent, resulting in inconsistent weights on both sides and affecting the specific counterweight effect. Therefore, the present case is designed with connecting rod 505, rubber sleeve 506, spring 507 and pressure plate 502, so that when replacing the number of counterweight plates 503, the user can first pull up the connecting rod 505 to make the pressure plate 502 out of the range of threaded rod 2 501, and then put the counterweight plate 503 on the outer wall of threaded rod 2 501, and finally loosen the connecting rod 505. Once the number of counterweight plates 503 on both sides is inconsistent, a cavity will appear on one side when the pressure plate 502 is pressed down, thereby ensuring the consistency of the number of counterweight plates 503 on both sides, effectively avoiding the problem that only manually replacing the counterweight plates will easily cause the number of counterweight plates on both sides to be consistent, resulting in inconsistent weights on both sides and affecting the specific counterweight effect.

[0045] Although the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
