[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0015] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the scope of the invention. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0016] Please see Figures 1-4 The 3D printing equipment constant temperature working cylinder device in the preferred embodiment includes a housing 1 and a cover 2; the cover 2 is disposed on the top of the housing 1. Two racks 3 are respectively installed on the two side walls of the inner cavity of the housing 1; The power mechanism 4 is located inside the housing 1 and extends through the cover 2; The air outlet component 5 is sleeved on the power mechanism 4 and meshes with the rack 3; The thermostat 6 is embedded in the top of the cover 2 and connected to the air outlet 5 through the connecting pipe 7. It is used to generate constant temperature air and provide a constant temperature environment for the 3D printing working cylinder. The power mechanism 4 is used to drive the air outlet 5 to move up and down; the rack 3 is used to rotate and discharge air during the up and down movement of the air outlet 5, so as to improve the uniformity of air discharge.

[0017] Specifically, refer to Figure 3 The power mechanism 4 includes a support plate 41 inside the housing 1, which provides rotatable support for the bottom end of the threaded rod 42; the threaded rod 42, which is rotatably mounted on the support plate 41 at the bottom and rotatably passes through the cover 2 at the top, drives the lifting plate 51 to rise and fall by rotation; two limiting rods 43 respectively set between the cover 2 and the support plate 41, which limit and guide the rise and fall of the lifting plate 51 to ensure that the lifting plate 51 moves smoothly; and a servo motor 44 set on the top of the cover 2 and whose output shaft is connected to the top end of the threaded rod 42, which serves as a power source to drive the threaded rod 42 to rotate.

[0018] Specifically, refer to Figure 2 and Figure 4 The air outlet component 5 includes a lifting plate 51 sleeved on the outer wall of the threaded rod 42 and the limiting rod 43. The lifting plate 51 is threadedly connected to the threaded rod 42 and slidably engaged with the limiting rod 43. The lifting plate 51 has a U-shaped plate structure and moves up and down along the limiting rod 43 under the drive of the threaded rod 42. Two rotary joints 52 are respectively set on both ends of the lifting plate 51. The rotary joints 52 are connected to the thermostat 6 through a connecting pipe 7 and are used to transmit constant temperature air. The rotary joints 52 can rotate to ensure that the air path is connected when the air outlet duct 53 rotates. The air outlet duct 53, which is connected to the rotating shaft of the rotary joints 52, is used to discharge constant temperature air. Its rotation can make the air outlet more uniform. A gear 54 sleeved on the outer wall of the air outlet duct 53 and meshing with the rack 3 meshes with the rack 3 during the lifting process of the lifting plate 51, driving the air outlet duct 53 to rotate.

[0019] Specifically, refer to Figure 2 and Figure 4 The air outlet duct 53 is provided with several air outlets; the number of air outlets is not less than ten and they are arranged in a ring array on the outer wall of the air outlet duct 53. By setting multiple air outlets and arranging them in a ring array, the air outlet can be made more uniform.

[0020] Specifically, refer to Figure 2 and Figure 4 The cover 2 and the housing 1 are detachably connected by a screw. When maintenance is required, the cover 2 can be disassembled by twisting in the reverse direction. Since the power mechanism 4 and the air outlet 5 are both located on the cover 2, when the cover 2 is removed, the power mechanism 4 and the air outlet 5 are taken out of the housing 1 together for maintenance or repair.

[0021] Working principle During operation, the thermostat 6 generates constant temperature air, which is delivered to the rotary joint 52 of the air outlet 5 through the connecting pipe 7 and then enters the air outlet duct 53; at the same time, the servo motor 44 starts, driving the threaded rod 42 to rotate. Since the lifting plate 51 is threadedly connected to the threaded rod 42 and slides with the limit rod 43, the rotation of the threaded rod 42 drives the lifting plate 51 to move up and down along the limit rod 43. During the up-and-down movement of the lifting plate 51, the gear 54 on the outer wall of the air outlet 53 meshes with the rack 3 on the inner side wall of the housing 1, and the gear 54 drives the air outlet 53 to rotate. While rotating, the air outlet 53 moves up and down with the lifting plate 51, thereby blowing constant temperature air evenly into the 3D printing working cylinder to ensure a uniform temperature distribution inside the working cylinder.

[0022] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
