Due to the slow dripping of the paint, it is easy to form drip marks on the outside of the pump casing, affecting the aesthetics of the finished product, so there is a certain room for improvement.

[0022] See also Figure 1-Figure 4The utility model provides an embodiment: a paint dipping device for pump casing production, comprising a paint dipping box 1, a protective cover 2 is arranged at the top of the paint dipping box 1, and a servo motor 12 is installed at the bottom end of the back side of the protective cover 2, a screw rod 13 is installed at the top of the servo motor 12, and both ends of the screw rod 13 are connected to the back side of the protective cover 2 through a support bearing 3, a lifting block 7 is sleeved on the outside of the screw rod 13, and the front side of the lifting block 7 extends to the inside of the protective cover 2, and a support rod 6 is installed on the front side of the bottom end of the lifting block 7;

[0023] A guide block is installed at the bottom end of the support rod 6, and a guide groove is opened at the top end of the lifting sleeve rod 5. The support rod 6 and the lifting sleeve rod 5 form an up and down sliding structure. At the same time, the sliding distance of the lifting sleeve rod 5 is equal to twice the distance between the eccentric shaft 804 and the axis of the gear 801;

[0024] Specifically, Figure 1 , Figure 2 , Figure 3 As shown, when in use, the lifting sleeve rod 5 slides up and down outside the support rod 6, so that the pump housing can perform a higher frequency up and down oscillation in the single up and down movement process, so that the pump housing can quickly throw off the excess paint after the paint is dipped, thereby improving the quality and efficiency of subsequent drying;

[0025] The bottom end of the support rod 6 is sleeved with a lifting rod 5, the bottom end of the lifting rod 5 is installed with a triangular prism 4, and the bottom end of the outer side of the triangular prism 4 is provided with an adjustment mechanism 9;

[0026] The adjustment mechanism 9 includes a support plate 901 installed at the bottom end of the outer side of the triangular prism 4, and a first ring 902 is installed on the outside of the top of the support plate 901, an extension plate 903 is penetrated inside the first ring 902, and a second ring 904 is arranged on the outer side of the top of the extension plate 903, and the second ring 904 sleeves the support plate 901 inside, and a spring 905 is installed on one end of the extension plate 903 close to the triangular prism 4, and one end of the spring 905 is connected to the outer wall of the second ring 904;

[0027] The support plate 901 and the extension plate 903 form a left-right sliding structure through the action of the first ring 902 and the second ring 904. At the same time, there are three support plates 901 in total, and the support plates 901 are triangularly distributed on the triangular prism 4;

[0028] Specifically, Figure 1 , Figure 4 As shown, when in use, the elastic effect of the spring 905 is utilized to make the extension plate 903 expand outward, thereby changing the position of the limit block 11 to achieve the bottom clamping effect of the pump casings of different diameters;

[0029] One end of 9 is installed with 10, and both sides of the top of 10 are installed with 11, and the front sections of both sides of 7 are provided with 8, and 8 is used to drive 5 to slide up and down along the outside of 6, so as to realize the up and down vibration of the pump housing;

[0030] A support block 10 is installed at one end of the adjustment mechanism 9, and limit blocks 11 are installed on both sides of the top of the support block 10. The front sections of both sides of the lifting block 7 are provided with synchronous oscillation mechanisms 8, which are used to drive the lifting sleeve rod 5 to slide up and down along the outside of the support rod 6, thereby realizing the up and down oscillation of the pump housing;

[0031] The synchronous oscillation mechanism 8 includes a gear 801 installed on the outside of the lifting block 7, and an eccentric shaft 804 is installed on the outside of the gear 801, and a movable rod 803 is sleeved on the outside of the eccentric shaft 804, and a connecting rod 806 is correspondingly installed on the outside of the lifting sleeve rod 5 below the gear 801, and a rotating sleeve 805 is sleeved on one end of the outside of the connecting rod 806, and the bottom end of the rotating sleeve 805 is welded to the bottom end of the movable rod 803, and a tooth plate 802 is meshed inside the gear 801, and the inner side of the tooth plate 802 is connected to the inner wall of the protective cover 2;

[0032] The top end of the movable rod 803 is rotatably connected to the gear 801 through the action of the eccentric shaft 804, and the bottom end of the movable rod 803 is rotatably connected to the connecting rod 806 through the action of the rotating sleeve 805;

[0033] The gear 801 meshes with the toothed plate 802 and rotates four times. The length of the toothed plate 802 is equal to half of the descending length of the lifting block 7.

[0034] Specifically, Figure 1 , Figure 3 As shown, when in use, the movement of the lifting block 7 drives the gear 801 to move synchronously, and then cooperates with the tooth plate 802 to make the gear 801 itself rotate synchronously, so as to cooperate with the movable rod 803 and other means to achieve the up and down reciprocating traction effect on the lifting sleeve rod 5, and the up and down reciprocating movement is carried out with the single descent or single ascent of the pump shell, so that the pump shell can automatically and directly vibrate and throw out excess paint after the paint immersion is completed.

[0035] Working principle: When the utility model is used, the support block 10 is first pressed inwards to make the first ring 902 shrink inwards first, and then the pump housing is sleeved on the outside of the triangular prism 4 from bottom to top, and the first ring 902 is loosened. The elastic effect of the spring 905 is used to make the first ring 902 expand outwards along the support plate 901, so that the support block 10 moves outwards, and the limit block 11 is used to clamp the inner wall of the pump housing, and the support effect of the support block 10 is cooperated to achieve the limit fixing effect of the pump housings of different diameters;

[0036] Secondly, by starting the servo motor 12, the screw rod 13 rotates, so that the lifting block 7 moves downward along the through hole of the protective cover 2, so that the lifting block 7 drives the pump housing below into the interior of the immersion paint box 1 to achieve the immersion paint effect on the pump housing;

[0037] Finally, the lifting block 7 is reset and raised. When the lifting block 7 rises to a distance from one end, the gear 801 driven by the lifting block 7 contacts and meshes with the tooth plate 802, thereby causing the gear 801 to rotate, thereby driving the eccentric shaft 804 to rotate. Since the eccentric shaft 804 is connected to the movable rod 803, one end of the movable rod 803 moves, and the other end of the movable rod 803 presses the rotating sleeve 805 downward, so that the rotating sleeve 805 pushes the lifting sleeve rod 5 downward through the connecting rod 806. During the continuous rotation of the gear 801, the bottom end of the movable rod 803 pushes and pulls the rotating sleeve 805 up and down, so that the lifting sleeve rod 5 oscillates up and down along the support rod 6, and then drives the pump casing that has been dipped in paint to move synchronously, thereby utilizing the inertia of the up and down oscillations to synchronously cause the pump casing to throw out excess paint downward during the rising process.
