DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1

[0020] See also Figure 1-3 The utility model provides the following technical solutions: a new type of laser engraving additive unloading hopper, including a unloading hopper body 1, a discharge port 3 is arranged at the lower end of the unloading hopper body 1, a valve 4 is arranged on the side of the discharge port 3, a support plate 5 is arranged on the lower end surface of the unloading hopper body 1, a support rod 2 is arranged at the lower end corner of the support plate 5, a feed hopper 8 is arranged on one side of the upper end of the unloading hopper body 1, a laser engraving additive stirring and dredging mechanism 7 is arranged at the upper center position of the unloading hopper body 1, and a unloading hopper inner wall cleaning mechanism 6 is arranged on the other side of the upper end of the unloading hopper body 1.

[0021] Specifically, the inner wall cleaning mechanism 6 of the discharge hopper includes a scraper 61, a lifting frame 62, a screw 63, a motor 64 and a guide assembly 65. A motor 64 is arranged on the other side of the upper end of the discharge hopper body 1, a screw 63 is arranged on the output end of the motor 64, a lifting frame 62 is arranged on the surface of the screw 63, a scraper 61 is arranged on the outer side of the lifting frame 62, and a guide assembly 65 is arranged inside the other side of the lifting frame 62.

[0022] By adopting the above technical solution, the new laser engraving additive is poured into the interior of the discharge hopper body 1 through the feed hopper 8. Since a lot of material will remain on the inner wall of the discharge hopper body 1 when it is used for a long time, at this time, by turning on the motor 64, the motor 64 drives the screw 63 to rotate through the output end, and the rotation of the screw 63 drives the lifting frame 62 to descend. The descent of the lifting frame 62 drives the scraper 61 to descend, so that the inner wall of the discharge hopper body 1 can be cleaned.

[0023] Specifically, the guide assembly 65 includes a through hole 651 and a guide rod 652. The guide rod 652 is provided inside the other side of the lifting frame 62. The through hole 651 corresponding to the guide rod 652 is provided inside the other side of the lifting frame 62.

[0024] By adopting the above technical solution, the lifting frame 62 slides on the surface of the guide rod 652 when it is lifted or lowered, thereby improving the stability of the lifting frame 62 during the lifting process.

[0025] Specifically, the lower end of the screw 63 is rotatably connected to the inner wall of the discharge hopper body 1 through a bearing.

[0026] By adopting the above technical solution, the arrangement of the structure can avoid the problem of the screw rod 63 being stuck during rotation.

[0027] When the present embodiment is in use, the new laser engraving additive is poured into the interior of the discharge hopper body 1 through the feed hopper 8. Since a lot of material will remain on the inner wall of the discharge hopper body 1 after long-term use, the motor 64 is turned on at this time. The motor 64 drives the screw 63 to rotate through the output end. The rotation of the screw 63 drives the lifting frame 62 to descend. The descent of the lifting frame 62 drives the scraper 61 to descend, so as to clean the inner wall of the discharge hopper body 1. When the lifting frame 62 is lifted, it slides on the surface of the guide rod 652 at the same time, thereby improving the stability of the lifting frame 62 during the lifting process.

[0028] Example 2

[0029] The difference between this embodiment and the embodiment 1 is that the laser engraving additive stirring and unblocking mechanism 7 comprises a stirring shaft 71, a second motor 72, a stirring rod 1 73 and an unblocking rod 75. The second motor 72 is arranged at the center of the upper end of the discharge hopper body 1, the output end of the second motor 72 is arranged with a stirring shaft 71, the upper end surface of the stirring shaft 71 is arranged with a stirring rod 1 73, and the lower end surface of the stirring shaft 71 is arranged with an unblocking rod 75.

[0030] By adopting the above technical solution, since the new laser engraving agent may have a caking problem inside the discharge hopper body 1, by turning on the motor 2 72, the motor 2 72 drives the stirring shaft 71 to rotate through the output end, and the stirring shaft 71 rotates to drive the stirring rod 1 73 to stir the laser engraving agent. At the same time, the stirring shaft 71 drives the unblocking rod 75 to rotate, thereby unblocking the laser engraving agent at the discharge port 3 to prevent the laser engraving agent from being blocked at the discharge port 3.

[0031] Specifically, a stirring rod 2 74 is disposed on the upper end surface of the stirring shaft 71 near the stirring rod 1 73, and the stirring rod 1 73 and the stirring rod 2 74 are disposed on the surface of the stirring shaft 71 in a staggered manner.

[0032] By adopting the above technical solution and setting the stirring rod 74, the stirring efficiency of the laser engraving additive can be improved.

[0033] When this embodiment is in use, since the new laser engraving agent may have a caking problem inside the discharge hopper body 1, by turning on the motor 2 72, the motor 2 72 drives the stirring shaft 71 to rotate through the output end, and the stirring shaft 71 rotates to drive the stirring rod 1 73 to stir the laser engraving agent. At the same time, the stirring shaft 71 drives the unblocking rod 75 to rotate, thereby unblocking the laser engraving agent at the discharge port 3 to avoid the laser engraving agent from being blocked at the discharge port 3. By setting the stirring rod 2 74, the stirring efficiency of the laser engraving agent can be improved.

[0034] Working principle and use process of the utility model: When the utility model is used, the new laser engraving additive is poured into the interior of the discharge hopper body 1 through the feed hopper 8. Since the inner wall of the discharge hopper body 1 will have more materials left after long-term use, the motor 64 is turned on at this time, and the motor 64 drives the screw 63 to rotate through the output end, and the screw 63 rotates to drive the lifting frame 62 to descend, and the lifting frame 62 descends to drive the scraper 61 to descend, so as to clean the inner wall of the discharge hopper body 1. When the lifting frame 62 is lifted, it slides on the surface of the guide rod 652 at the same time. Thereby improving the stability of the lifting process of the lifting frame 62; since the new laser engraving agent may have a caking problem inside the discharge hopper body 1, at this time, by turning on the motor 2 72, the motor 2 72 drives the stirring shaft 71 to rotate through the output end, and the rotation of the stirring shaft 71 drives the stirring rod 1 73 to stir the laser engraving agent. At the same time, the stirring shaft 71 drives the unblocking rod 75 to rotate, thereby unblocking the laser engraving agent at the discharge port 3 to avoid the laser engraving agent from being blocked at the discharge port 3. By setting the stirring rod 2 74, the stirring efficiency of the laser engraving agent can be improved.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
