[0048] refer to Figures 1 to 3At least one embodiment provides a sheet metal pretreatment device before painting, including: a placement part 1, which includes a placement groove 11 serving as a sheet metal conveying channel for placing sheet metal parts that need to be pretreated, and the sheet metal parts move forward in the placement groove 11 when rolling and subjected to force; a shaping mechanism 2, which includes a shaping barrel 21 for rolling the sheet metal parts to shape them and a central shaft 23 running through the shaping barrel 21, and when the sheet metal parts are pretreated, the central shaft 23 drives the shaping barrel 21 to roll the sheet metal parts; a power mechanism 3, which is connected to the central shaft 23 and is suitable for driving the shaping barrel 21 to rotate, and is used to provide power for the shaping barrel 21 to rotate; the shaping mechanism 2 also includes a crushing component 24 running through the side wall of the shaping barrel 21, which is used to crush impurity blocks on the surface of the sheet metal parts when the shaping barrel 21 shapes the sheet metal parts; the power mechanism 3 is electrically connected to an external control system for controlling the operation and stop of the several parts, as well as transmitting signals.

[0049] In some embodiments, the placement groove 11 passes through the upper portion of the placement groove 11 ; the shaping barrel 21 is provided with a guide hole 22 serving as a passage for the crushing assembly 24 , so as to ensure the accuracy of the movement path of the crushing assembly 24 .

[0050] In some embodiments, the placement groove 11 passes through the two ends of the placement piece 1 to facilitate the reception and release of the sheet metal piece; one end of the crushing component 24 is movably inserted into the side of the central axis 23, and the other end passes through the guide hole 22; so that the end of the crushing component 24 is suitable for contacting the impurity blocks on the sheet metal piece to crush them.

[0051] In some embodiments, there are multiple shaping mechanisms 2, which are used to shape the sheet metal multiple times, and at the same time, the crushing components 24 crush the impurity blocks on the sheet metal multiple times; the central axis 23 of at least one of the shaping mechanisms 2 is connected to the power mechanism 3, so that when one of the shaping barrels 21 rotates to drive the sheet metal forward, the sheet metal drives the other shaping barrels 21 to rotate synchronously, so that a single power mechanism 3 drives multiple shaping mechanisms 2 to rotate synchronously through the sheet metal as a medium; multiple crushing components 24 are staggered to achieve an ideal crushing effect.

[0052] In some embodiments, a channel for sheet metal parts to pass through is provided between the shaping barrel 21 and the bottom of the placement tank 11; and the guide holes 22 on the shaping barrel 21 are distributed in a circular array.

[0053] In some embodiments, the crushing assembly 24 includes a moving shaft 25, an elastic member 28 and a crushing head 29; one end of the moving shaft 25 is movably inserted in the central shaft 23, and the other end is located in the guide hole 22, for ensuring that the moving shaft 25 can move in the axial direction of the guide hole 22; the middle part of the moving shaft 25 is connected to the central shaft 23 through the elastic member 28, for driving the crushing assembly 24 to reset after it is separated from the sheet metal; the crushing head 29 is fixedly connected to the end of the moving shaft 25.

[0054] In some embodiments, the elastic member 28 is a spring; the portion of the crushing head 29 connected to the moving shaft 25 is located in the guide hole 22, and the tip of the crushing head 29 away from the moving shaft 25 is located outside the guide hole 22, to ensure that the crushing head 29 can contact the sheet metal.

[0055] In some embodiments, the motion shaft 25 includes a thin shaft 26 inserted into the central shaft 23 and a thick shaft 27 for installing the crushing head 29; one end of the elastic member 28 is connected to the intersection of the thick shaft 27 and the thin shaft 26, and the other end is connected to the side of the central shaft 23.

[0056] In some embodiments, the power mechanism 3 includes a rotating shaft 32 connected to the central shaft 23 and a motor 31 that provides power to the rotating shaft 32; the pretreatment equipment also includes a dust collecting part 4 for absorbing impurities, which is used to absorb the crushed impurity fragments.

[0057] In some embodiments, the elastic member 28 is located outside the thin shaft 26 ; the dust collecting member 4 is located above the placement groove 11 ; and the dust collecting member 4 is located between the two shaping barrels 21 .

[0058] Working principle: before starting to use a sheet metal pretreatment device before painting, the placement slot 11 of the placement part 1 is connected to the sheet metal conveying device and the sheet metal receiving device; when starting to use a sheet metal pretreatment device before painting: the sheet metal conveying device conveys the sheet metal to be pretreated into the placement slot 11; at the same time, under the control of the external control system, the motor 31 drives the central shaft 23 to rotate through the rotating shaft 32, and the rotation of the central shaft 23 drives the shaping cylinder 21 to rotate synchronously; when the shaping cylinder 21 rotates, it presses the sheet metal to shape it, and drives the sheet metal to advance in the placement slot 11; at the same time, the sheet metal in the placement slot 11 contacts the shaping barrel 21 of the other shaping mechanism 2, thereby pushing the other shaping barrels 21 to rotate synchronously Rotation; During this process, when the crushing assembly 24 at the bottom of the shaping barrel 21 contacts the sheet metal, the crushing head 29 contacts the sheet metal, crushing or flattening the impurity blocks on the surface of the sheet metal. After the crushing head 29 contacts the impurity blocks on the sheet metal, the moving shaft 25 partially compresses the elastic member 28, and the moving shaft 25 is inserted into the central shaft 23; When the shaping barrel 21 continues to rotate, the crushing head 29 separates from the sheet metal, and under the action of the elastic member 28, the moving shaft 25 and crushing head 29 return to their original position; When the sheet metal continues to move to the next crushing assembly 24, the subsequent crushing assembly 24 contacts the flattened impurity blocks and crushes them; During this process, the dust collecting member 4 continues to work to suck away impurities on the sheet metal, thereby completing the cleaning of the sheet metal. During this process, the crushing head 29 intermittently contacts different positions of the sheet metal, creating small holes on the sheet metal, which facilitates the subsequent painting of the sheet metal; The above process is maintained until the work is completed.
