Technical Field

[0001] This utility model relates to the field of spray painting technology, specifically to a feeding device for a suspended spray painting line. Background Technology

[0002] Painting is a common practice for corrosion prevention and decoration of workpieces. The painting process mainly includes two methods: manual painting and automatic painting.

[0003] Automatic painting lines have the advantages of energy saving and environmental protection. However, some automatic painting lines use conveyor belts to send the workpieces to be painted into the painting booth. This means that the bottom surface of the workpieces cannot be effectively painted, and the loading and unloading of workpieces is limited to the two ends of the conveyor belt. The second method is very inconvenient to pick up and put down materials due to the limited placement of the workpieces. Therefore, there is an urgent need for a feeding device for suspended painting lines that provides stable feeding and convenient picking and putting down of materials. Summary of the Invention

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] Example 1:

[0033] The feeding device for the suspended spray painting line provided by this utility model works in conjunction with the spray booth to deliver the workpieces to be painted to the spray booth at the same speed. Figure 1 , 2 In the embodiments shown in 3 and 7, the slide rail 101 can be made of high-strength profiles such as steel plates or iron plates, and processed into the required shape by cold bending. The bracket 102 is used to support the slide rail 101, and the structure of the support frame includes a support column and a suspension beam, with the upper part of the slide rail 101 connected to the suspension beam.

[0034] The slide rail 101 is configured according to production needs, such as the storage location of workpieces to be processed and the safe location of workpieces after processing. After assembly, the slide rail 101 is in a closed state. To facilitate transportation, the slide rail 101 is segmented, and each segment has a mounting plate 104 at its end. Adjacent slide rail segments are connected via the mounting plates 104 and secured with bolts. A gap at the bottom of the slide rail 101 allows the hanging rod 103, which is attached to the chain, to travel.

[0035] The chain is slidably connected inside the slide rail 101. Specifically, the chain includes several first chain links 106 and several second chain links 108. The ends of each first chain link 106 and the ends of each second chain link 108 are hinged via a connecting block 107, allowing adjacent first chain links 106 and second chain links 108 to rotate left and right and up and down, thereby ensuring that the chain can turn and climb along the slide rail 101. Each first chain link 106 and each second chain link 108 is provided with a roller 105 that contacts the inner wall of the slide rail 101. Among them, the roller 105 at the first chain link 106 contacts the bottom of the slide rail 101. Since the roller 105 at the first chain link 106 carries the workpiece to be processed, the roller 105 at the first chain link 106 can be in the form of a double wheel. The roller 105 at the second chain link 108 contacts the side wall of the slide rail 101, mainly guiding the direction of the chain and not needing to bear excessive pressure. Therefore, the roller 105 at the second chain link 108 can be a single wheel. To reduce wear on the inner wall of the slide rail 101 caused by the roller 105, a rubber coating is provided on the outer edge of each roller 105.

[0036] One end of each hanging rod 103 can be suspended at the roller shaft of the first chain link 106 of the chain, and the other end of each hanging rod 103 is used to hang the workpiece to be processed.

[0037] The drive assembly is used to provide power for the movement of the chain. Specifically, the drive assembly includes a drive motor and levers 115. One optional driving method between the drive motor and the chain is that a wheel is rotatably connected to the bracket 102, and levers 115 are evenly distributed on the rim of the wheel. The drive motor drives the wheel to rotate, and the levers 115 on the rim of the wheel apply force to the roller shafts at each of the first chain links 106 of the chain to drive the chain.

[0038] like Figure 7 As shown, another optional driving method between the drive motor and the chain is that a conveyor belt 116 is rotatably connected to the bracket 102, and levers 115 are evenly distributed on the conveyor belt 116. The drive motor drives the conveyor belt 116 to rotate, and the levers 115 set on the conveyor belt 116 apply force to the roller shafts at each of the first chain links 106 of the chain to achieve the driving of the chain.

[0039] In order to reduce the load on the drive motor, the power output of the drive motor is reduced by a speed reducer.

[0040] Example 2:

[0041] Based on Example 1, such as Figure 4 In the embodiment shown, to prevent the workpiece from shaking during the conveying process, a stop block 112 is provided on the outer wall of each hanging rod 103, and a connecting plate 104 is provided between two adjacent hanging rods 103. The body of the connecting plate 104 is provided with two oblong holes 111, and the edge of each oblong hole 111 near the end of the connecting plate body is equidistant from the two hanging rods 103.

[0042] In use, when any hanging rod 103 is disturbed by external forces such as those generated by the paint spraying from the paint gun, the hanging rod 103 at the connecting plate 104 will transmit the external force to the other hanging rods 103 through the connecting plate 104 because the edge of each oval hole 111 near the end of the connecting plate body is equidistant from the two hanging rods 103. This will cancel out the external force and reduce the potential risk of uneven spraying caused by the shaking of the workpiece during the painting operation.

[0043] In this embodiment, to facilitate the connection between the connecting plate 104 and the hanging rod 103, each connecting plate 104 has a notch 110 on its body that communicates with each oval hole 111. At the same time, to prevent the hanging rod 103 from coming out of the notch 110, the spacing between the notches 110 is smaller than the spacing between the two hanging rods 103.

[0044] When connecting the connecting plate 104 and the hanging rod 103, first insert the hanging rod 103 into the oval hole 111 at one end through the notch 110. When hanging the adjacent hanging rod 103 into the other oval hole 111, tilt the adjacent hanging rod 103 and insert the adjacent hanging rod 103 into the oval hole 111 through the notch 110.

[0045] To further prevent the hanging rod 103 from coming off the notch 110, such as Figure 5In the illustrated embodiment, each notch 110 of each connecting plate 104 is hinged with a baffle 113. A torsion spring is provided between the baffle 113 and the body of the connecting plate 104. The torsion spring causes the opposite ends of the baffle 113 and the body of the connecting plate 104 to abut against the body of the connecting plate 104 in the natural state. In use, the hanging rod 103 can be inserted into the oblong hole 111 by pressing the baffle 113.

[0046] Example 3:

[0047] like Figure 6 In the illustrated embodiment, an inspection port is provided at the slide rail 101 to facilitate the installation, inspection, and maintenance of the chain. Through the inspection port, various operations such as chain assembly, chain inspection, and chain oiling can be performed. A cover plate 114 is movably connected to the inspection port, and the cover plate 114 can be fixed to the slide rail 101 with bolts.

[0048] Example 4:

[0049] like Figure 8 In the illustrated embodiment, during the painting operation, in order to rotate the workpiece hanging on the hanging rod 103, each hanging rod 103 is arranged in a split manner, and the lower rod body and the upper rod body are rotatably connected. Specifically, the lower end of the upper rod body is provided with a first flange 117, the upper end of the lower rod body is provided with a second flange 118 and a base 120. The base 120 is a hollow cylinder with an open bottom and a sealed top. A through groove is provided at the base 120, and the through groove extends radially along the base 120. The upper hanging rod passes through the through groove, so that the base 120 and the first flange 117 are concentrically arranged. The lower edge of the inner wall of the base 120 and the outer edge of the second flange 118 are provided with mutually cooperating threaded structures.

[0050] During assembly, the upper hanging rod is inserted into the base 120 through the through groove, the base 120 is moved down so that the top of the base 120 contacts the upper part of the first flange 117, and the lower edge of the base 120 and the outer wall of the second flange 118 are threaded together.

[0051] The bracket 102 is connected to the drive tooth 122 via the mounting base 121. When the hanging rod 103 moves to the drive tooth 122, the drive tooth 122 and the drive wheel 119 come into contact. Under the action of the drive tooth 122 and the drive wheel 119, the moving hanging rod 103 will rotate.

[0052] In this embodiment, to enable selective rotation of the hanging rod 103, the drive gear 122 and the mounting base 121 are movably connected. When rotation of the hanging rod 103 is not required, the relative positions of the drive gear 122 and the mounting base 121 can be adjusted so that the drive wheel 119 at the hanging rod 103 in its natural state does not contact the drive gear 122.

[0053] The above-described embodiments are merely preferred embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be covered within the protection scope of this utility model.
