In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

The content of the present invention will be further described in detail with reference to the specific embodiments, and fig. 1 and fig. 2 show the front view and the right view of the metal powder flattening device of the present invention, which mainly comprises a base plate 1, a supporting frame 2, a flattening assembly 3, a lifting driving portion 4, a material container 5, etc. Wherein the supporting frame 2 is detachably fixed to the upper plane of the base plate 1 by means of bolts. The material container 5 is arranged directly below the spreading assembly 3. The lifting driving part 4 is disposed between the supporting frame 2 and the leveling assembly 3 to drive the leveling assembly 3 to move up and down along the supporting frame 2 as a whole. The flattening assembly 3 includes a fixing frame 31, a first linear motion power element 32, a transmission shaft 33, a synchronous belt transmission mechanism 34, a clamping jaw mechanism 35 and a flattening head 36. The transmission shaft 33 is fixed on the bottom surface of the fixing frame 31 and passes through the supporting frame 2. The fixed frame 31 is driven by a first linear motion power element 32 to drive the transmission shaft 33 to move in the up-and-down direction relative to the supporting frame 2. The synchronous belt transmission mechanism 34 is fixed on the support frame 2 and drives the transmission shaft 33 to perform circumferential rotation motion. The clamping jaw mechanism 35 is fixed at the lower end of the transmission shaft 33 to realize the grabbing of the flattening head 36. The gripper mechanism 35 includes a gripper group 351 and a gripper cylinder 352 that drives the gripper group 351 to open and close. In the actual operation process, the flattening heads 36 are replaced every time when the flattening work is carried out for the rated times, so that excessive accumulation of the metal powder on the flattening heads is avoided, and the rated weight of the metal powder is effectively ensured to meet the use requirement. In addition, the time consumed by the conventional tile head cleaning and air drying operation is saved, the phenomenon of long-time shutdown is avoided, and the working efficiency is improved.

As a further optimization of the above metal powder flattening apparatus, the above flattening assembly 3 may be additionally provided with a positioning plate 37. The positioning plate 37 is fixed to the cylinder of the gripper cylinder 352 by means of the connecting rod 38 and is surrounded by the gripper block 351 (as shown in fig. 4). Thus, when the flattening head 36 is grabbed by the clamping jaw group 351, the top surface of the flattening head is opposite to the lower plane of the positioning plate 37, and the flattening head 36 is completely attached to the positioning plate 37 along with the continuation of the grabbing process, so that the flattening head is ensured to be always kept in a horizontal state, and the surface flatness of the metal powder after being flattened is ensured.

Furthermore, in view of improving the guiding performance of the operation of the spreading assembly 3, the metal powder spreading apparatus may be additionally provided with a guiding device, i.e., a slide rail slider assembly 6, wherein the slide rail is detachably fixed on the front side wall of the supporting frame 2 by means of bolts, and the slider is fixed on the rear side surface of the fixed frame 31 (as shown in fig. 3).

Furthermore, the above-mentioned flattening assembly 3 may be additionally provided with an elastic leaning mechanism 39. The elastic leaning mechanism 39 comprises an auxiliary support 391, an elastic transition component 392 and a pressing support 393 which are arranged in sequence just below the support frame 2, and the specific positions and the assembling relationship thereof are shown in fig. 4. During the gradual pressing of the container 5 against the support 393, it moves towards each other relative to the auxiliary support 391 and always exerts a resilient abutment force on the container 5 under the action of the resilient transition element 392. In this way, the material container 5 can be effectively pressed by the pressing support 393, so that the position change of the material container in the flattening process is prevented, and the smooth flattening process is ensured. In addition, the pressing force applied to the container 5 by the pressing bracket 393 is an elastic force, thereby preventing the occurrence of the pressure loss phenomenon.

In order to ensure the practical use effect of the elastic abutting mechanism 39 and the reliability of the working performance thereof, the following scheme can be referred to: the number of resilient transition members 392 is set to 2 sets, symmetrically distributed on the left and right sides of drive shaft 33 (as shown in fig. 4). As a specific refinement of the structure of the resilient transition assembly 392, it mainly comprises a first guide rod 3921, a first guide sleeve 3922 fitted to the first guide rod 3921, and a first cylindrical spring 3923, wherein the first guide rod 3921 and the first guide sleeve 3922 are respectively fixed on the pressing bracket 393 and the auxiliary bracket 391. The first cylindrical spring 3923 is sleeved on the first guide rod 3921 and pressed between the pressing bracket 393 and the auxiliary bracket 391 (as shown in fig. 6). In actual operation, the directionality of the movement of the pressing bracket 393 with respect to the auxiliary bracket 391 is ensured by the first guide lever 3921, and the downward pressure applied to the container 5 is always provided by the first cylindrical spring 3923. Of course, the number of the elastic transition elements 392 can be 3 sets, 4 sets, etc., and are circumferentially distributed along the central axis of the transmission shaft 33.

In order to prevent the rigid contact between the pressing bracket 393 and the container 5 and to prevent the container 5 from being damaged by pressure, an elastic rubber pad (not shown) may be provided on the bottom surface of the pressing bracket 393, and is preferably detachably disposed so as to facilitate a replacement operation of the elastic rubber pad during a later maintenance.

In addition, the metal powder flattening device further includes 2 sets of limiting mechanisms 310, which are symmetrically distributed along the left-right direction (as shown in fig. 5). Of course, in view of reducing the manufacturing cost, the number of the limiting mechanisms 310 may be set to one set, and include a bottom plate 3101, a second guide rod 3102, a second guide sleeve 3103, a second column spring 3104, and a top plate 3105 (as shown in fig. 6) on the premise of meeting the basic use requirement. The bottom plate 3101 is fixed on the cylinder body of the clamping jaw cylinder 352, and is provided with a mounting hole matched with the second guide sleeve 3103. The top plate 3105 is horizontally arranged right above the bottom plate 3101. The second guide bar 3102 extends downward from the bottom surface of the top plate 3101 and passes through the second guide sleeve 3103 to achieve connection with the fixed frame 31. The second column spring 3104 abuts between the bottom plate 3101 and the top plate 3105. Thus, the pressure value applied to the metal powder by the flattening head 36 is always kept in a floating state, and the flattening effect is ensured.

The limiting mechanism 310 further includes an adjusting bolt 3106 and a locking nut 3107 (shown in fig. 6). The adjusting bolt 3106 is vertically inserted and fixed to the top plate 3105, and is locked by a lock nut 3107. The adjusting bolt 3106 is always abutted against the upper top surface of the second column spring 3104. When the pressure value of the flat heads 36 applied to the metal powder needs to be adjusted, the locking nuts 3107 are loosened and the adjusting bolts 3106 are screwed.

Finally, the synchronous belt transmission mechanism 34 can be further refined, and mainly comprises a first synchronous wheel, a second synchronous wheel, a synchronous belt, a servo rotating motor fixed on the support frame 2 and the like. Wherein the second synchronizing wheel is fixed with the transmission shaft 33 in a key connection manner. The first synchronizing wheel is fixed at the output end of the servo rotating motor, and drives the second synchronizing wheel under the action of the synchronizing belt, so as to drive the transmission shaft 33 to perform circumferential rotating motion (as shown in fig. 3).
