Description

Technical Field

[0001] This utility model belongs to the field of workpiece spraying technology, specifically relating to a secondary lifting tool for a coating suspension conveyor line. Background Technology

[0002] Currently, in the manufacturing process of photovoltaic polyurethane composite frames, coating is typically applied to prevent corrosion from ultraviolet rays and chemicals, which could affect the lifespan of the frame, enhance its corrosion resistance to acids, alkalis, and salts, reduce potential-induced degradation (PID) phenomena, and make the frame surface smoother, more aesthetically pleasing, and improve the overall visual effect.

[0003] Suspended conveyor lines play a crucial role in the coating process, and their selection and planning directly affect the efficiency of the coating production line and the quality of the products.

[0004] The existing overhead conveyor line uses a secondary lifting device with high degree of freedom and large sway when spraying photovoltaic polyurethane composite frame preparation. This makes it easy for products to accidentally touch each other, resulting in poor surface spraying effect. In addition, the products cannot rotate in the spray booth, resulting in poor spraying effect. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing secondary lifting tools have high degrees of freedom and large sway, which leads to the workpieces colliding with each other, resulting in poor surface spraying effect and the workpieces not being able to rotate, thus affecting the spraying effect.

[0006] To solve the above-mentioned technical problems, the present invention provides a secondary lifting device for a painting suspension conveyor line, comprising a first positioning cone wheel, a first bearing provided on the inner side wall of the first positioning cone wheel, a rotating shaft interference-connected to the inner side wall of the first bearing, a second bearing interference-connected to the side surface of the rotating shaft, a second positioning cone wheel fixedly connected to the side surface of the second bearing, and a gear plate fixedly connected to the side surface of the rotating shaft.

[0007] Through the above technical solution, when this device is installed on the primary lifting device, the first positioning cone wheel and the second positioning cone wheel are fitted into the two locking holes set on the upper and lower parts of the primary lifting device, so that the freedom of the first positioning cone wheel and the second positioning cone wheel is locked, so that they cannot wobble and can only rotate in the circumferential direction. This can prevent wobbling and thus prevent the workpiece installed below from wobbling. It can effectively avoid the problem of poor surface spraying effect caused by the wobbling and collision between workpieces. In addition, the gear plate and the chain work together to make the rotating shaft and the hanging rod drive the workpiece to rotate, thereby making the workpiece rotate and improving the spraying effect of the workpiece.

[0008] The present invention is further configured such that a mounting groove is provided on the side surface of the rotating shaft near the lower end, and a hanging rod is movably connected to the inner side wall of the mounting groove.

[0009] The present invention is further configured such that a screw is threadedly connected to the side surface of the rotating shaft, and the side surface of the screw is threadedly connected to the hanging rod.

[0010] The above technical solution allows the hanging rod to be installed in the mounting groove of the rotating shaft using a screw.

[0011] The present invention is further configured such that a leaf spring is movably connected to the side surface of the hanging rod, and a screw is threadedly connected to the side surface of the leaf spring, and the side surface of the screw is threadedly connected to the hanging rod.

[0012] With the above technical solution, the leaf spring can be installed on the hanging rod by screw two. The workpiece can be inserted by bending the leaf spring. After the leaf spring is loosened, the leaf spring and the hanging rod lock the workpiece in place, fixing the position of the workpiece and facilitating subsequent spraying of the workpiece surface.

[0013] The present invention is further provided that the side surfaces of the hanging rod and the rotating shaft are galvanized.

[0014] Through the above technical solution, galvanizing forms a protective layer on the surface of the hanging rod and the rotating shaft to resist corrosion. This method has the characteristics of strong acid and alkali resistance and good stability, which can effectively extend its service life.

[0015] The beneficial effects of this utility model are as follows:

[0016] (1) The first positioning cone wheel and the second positioning cone wheel enable the device to be fitted into the clasp of the primary lifting tool. The freedom of the first positioning cone wheel and the second positioning cone wheel restricts them so that they cannot shake and can only rotate in the circumferential direction, thereby preventing the workpiece installed below from shaking and avoiding the problem of poor surface coating effect caused by the collision between workpieces.

[0017] (2) The first bearing and the second bearing enable the shaft and the hanging rod to rotate. When the gear plate meshes with the chain, the rotation causes the workpiece to rotate. Attached Figure Description

[0020] 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. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] like Figure 1 As shown, this embodiment of a secondary lifting device for a painting overhead conveyor line includes a first positioning cone wheel 1. A first bearing 2 is provided on the inner side wall of the first positioning cone wheel 1. A rotating shaft 3 is interference-fitted to the inner side wall of the first bearing 2. A mounting groove 7 is provided near the lower end of the side surface of the rotating shaft 3. A hanging rod 8 is movably connected to the inner side wall of the mounting groove 7. A screw 9 is threadedly connected to the side surface of the rotating shaft 3, and the side surface of the screw 9 is threadedly connected to the hanging rod 8. A second bearing 4 is interference-fitted to the side surface of the rotating shaft 3. A second positioning cone wheel 5 is fixedly connected to the side surface of the second bearing 4. When this device is installed on the primary lifting device, the first positioning cone wheel 1 and the second positioning cone wheel 5 are fitted into two locking holes provided above and below the primary lifting device, thus locking the freedom of the first positioning cone wheel 1 and the second positioning cone wheel 5, preventing them from shaking and allowing only circumferential rotation. This avoids shaking and allows the lower-mounted... To prevent workpieces from shaking, the problem of poor surface coating caused by workpieces wobbling and bumping is effectively avoided. A gear plate 6 is fixedly connected to the side surface of the rotating shaft 3. The gear plate 6 cooperates with the chain to make the rotating shaft 3 and the hanging rod 8 drive the workpiece to rotate, thereby improving the coating effect of the workpiece. A leaf spring 10 is movably connected to the side surface of the hanging rod 8. The leaf spring 10 can cooperate with the hanging rod 8 to lock and limit the installed workpiece. A screw 11 is threadedly connected to the side surface of the leaf spring 10. The side surface of the screw 11 is threadedly connected to the hanging rod 8. The side surfaces of the hanging rod 8 and the rotating shaft 3 are all galvanized. The first bearing 2 and the second bearing 4 can effectively reduce the wear of the rotating shaft 3 and improve its service life. The galvanizing treatment forms a protective layer on the surface of the hanging rod 8 and the rotating shaft 3 to resist corrosion. This method has the characteristics of strong acid and alkali resistance and good stability, which can effectively extend its service life.

[0022] The working principle of this utility model is as follows: When using this device, the first positioning cone wheel 1 and the second positioning cone wheel 5 are sleeved in the two upper and lower clamping holes of the primary hanger. The whole device will only rotate in the circumferential direction without shaking in the clamping holes. At this time, the leaf spring 10 is pried open to insert the workpiece to be sprayed from below. After the leaf spring 10 is released, the leaf spring 10 and the hanging rod 8 clamp the workpiece and position it to prevent it from shaking during the spraying process. When the gear plate 6 cooperates with the chain, the rotating shaft 3, the hanging rod 8 and the workpiece can rotate in the spray booth.

[0023] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
