Description

Technical Field

[0001] The invention relates to the field of elevator parts processing, and in particular to a spraying device for elevator parts processing. Background Art

[0002] The service life of an elevator is inextricably linked to the quality of its parts. During the production of elevator parts, in order to ensure that the surface of the elevator parts is isolated from the external environment and avoid corrosion, paint and other coatings will be sprayed on the surface of the elevator parts so that a protective layer is attached to the surface of the workpiece, thereby increasing the service life of the workpiece and improving the overall aesthetics of the elevator.

[0003] An automated spraying production line for elevator parts with publication number CN117358479A in the prior art can clean the elevator parts to reduce the impact of dust on the spraying of elevator parts, and can screen out unqualified elevator parts to avoid spraying of elevator parts, thereby reducing the waste of paint and the time spent on spraying unqualified workpieces, thereby improving the processing efficiency of the device.

[0004] Although the above-mentioned prior art can clean the accessories before spraying, in the actual processing process, the cleaning device cannot be flexibly adjusted according to the processed accessories. When spraying the I-shaped or U-shaped mounting frame of the elevator accessories, it cannot be flexibly adjusted to clean both sides. Therefore, it is necessary to install cleaning devices on both sides, which not only increases the cost, but also cannot be used when spraying and cleaning the elevator plate accessories, which is relatively wasteful. Summary of the invention

[0013] In the above technical solution, further, a pair of guide rods are fixedly connected to the top of the connecting rod and are arranged through the top of the adjusting plate.

A third spring is fixedly connected between the card slots and the round balls, and a plurality of limit slots are provided on the inner side of the adjustment frame at positions corresponding to the round balls. When the adjustment plate is pushed, the round balls will be squeezed to slide toward the inner side of the card slots and out of the inner side of the limit slots, and the third spring will be compressed at the same time.

[0016] In the above technical solution, further, a rectangular groove is opened on the top of the support plate, and the top of the guide plate is fixedly connected with a rectangular rod and slidably connected to the inner side of the rectangular groove. Through the setting of the rectangular groove and the rectangular rod, the sliding of the guide plate can be guided to prevent the guide plate from swinging randomly following the pull rod, thereby improving the stability of the device during adjustment.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

DETAILED DESCRIPTION

[0029] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0030] like Figure 1-Figure 8The spraying device for processing elevator parts shown in the figure comprises a conveyor line 1, which is composed of a motor, a conveyor roller and a conveyor belt. The conveyor roller is driven to rotate by the motor, thereby driving the conveyor belt to be transmitted between multiple conveyor rollers to realize the transportation of materials, and a first support frame 2 and a second support frame 3 are arranged on the conveyor line 1. A spraying mechanism 4 for spraying paint is arranged inside the second support frame 3. The spraying mechanism 4 is mainly composed of a paint spraying tube and a multi-axis moving mechanism, which can realize multi-directional spraying of workpieces. It is a mature mechanism in the prior art and will not be described in detail here. A plurality of fixed frames 5 are arranged inside the first support frame 2, such as Figure 3 The hinge of the fixed frame 5 shown in the figure may be provided with an angle limit frame for limiting the rotation angle to avoid excessive rotation angle, and the bottoms of several fixed frames 5 are connected by hinges, and the inner sides of the fixed frames 5 are fixedly connected with air injection pipes 6, and the tops of the fixed frames 5 are provided with a limit mechanism for adjusting the folding position, and the top of one of the fixed frames 5 located in the middle is fixedly connected with a connecting frame 8, and the top of the connecting frame 8 is fixedly connected with a rack 9 and is arranged through the top of the first support frame 2, and the outer wall of the rack 9 is fixedly connected with a limit plate 10 and abuts against the top of the first support frame 2, and the inner side of the first support frame 2 is provided with an adjustment mechanism for adjusting the folding of the fixed frame 5;

[0031] When the elevator panel is to be sprayed, the elevator panel is placed on the conveyor line 1. Then, when the panel passes through the first frame 2, the external fan is controlled to start, and the air is transported to the jet pipe 6 through the hose for spraying, so as to blow off the dust and impurities on the surface of the panel. Then, as the conveyor line 1 continues to transport the elevator panel to the bottom of the second frame 3, the spraying mechanism 4 can be controlled to start spraying the elevator panel.

[0032] The adjusting mechanism includes an upper servo motor 11, a pair of fixed plates 12 are fixedly connected to the top of the inner side of the first support frame 2, a winding roller 13 is rotatably connected between the fixed plates 12, the upper servo motor 11 is fixedly connected to one of the side walls of the fixed plates 12, and the output end of the upper servo motor 11 passes through the fixed plate 12 and is fixedly connected to the winding roller 13, a disc 14 is fixedly connected to the middle of the outer wall of the winding roller 13, and a quarter of the outer wall of the disc 14 is fixedly connected to a plurality of tooth blocks 15 meshing with the rack 9, pulley seats 16 are fixedly connected to both sides of the top of the first support frame 2, a pair of pull rings 17 are fixedly connected to the top of two of the fixed frames 5 at both ends, and a pull wire 18 is fixedly connected between each pair of pull rings 17, the top of the pull wire 18 passes through the outer wall of the pulley seat 16 and is wound around the winding roller 13, and the directions of the pull wires 18 wound around the winding roller 13 are arranged in opposite directions, a top plate 19 is fixedly connected to the top of the rack 9, and a first spring 20 is fixedly connected between the top plate 19 and the top of the first support frame 2;

[0033] When the cleaning position needs to be adjusted for spraying the I-beam or U-shaped frame, first, according to the size of the workpiece to be sprayed, the limit sliding frame 24 at the corresponding position on the limit mechanism is pushed out, and the connection between the fixed frame 5 at the position to be folded can be released, and then the upper servo motor 11 is controlled to start and drive the winding roller 13 and the disc 14 to rotate, so that the pull wire 18 wound in opposite directions on the winding roller 13 is released to both sides at the same time, and then guided by the pulley seat 16, the fixed frame 5 with the limit released at both ends is rotated 90 degrees around the hinge, and at the same time, the middle fixed frame 5 is limited by the connecting frame 8, the rack 9 and the limit plate 10, so that its position is different, thereby driving the jet pipe 6 to flip to both sides to realize the adjustment of the jet position, and the elevator accessories of different styles and specifications can be cleaned to ensure the quality of the elevator accessories spraying. When resetting, the upper servo motor 11 can be controlled to rotate in the opposite direction;

[0034] When spraying and cleaning higher I-beams or U-shaped plates, the limiting sliding frame 24 at the nearest position between the fixed frames 5 is opened for adjustment through the limiting mechanism, and as the upper servo motor 11 starts to unwind the pull wire 18, the fixed frames 5 on both sides gradually flip downward. Due to the limitation of the pull wire 18 position by the pulley seat 16, the more the fixed frames 5 on both sides flip downward, the more turns the winding roller 13 unwinds, thereby flipping the nearest connection of the fixed frames 5, and the winding roller 13 will drive the disc 14 to rotate to rotate the tooth block 15 to the meshing position with the rack 9. As the fixed frames 5 on both sides gradually flip downward, the rack 9 will be driven upward by the tooth block 15, and the connecting frame 8 and the fixed frame 5 will be pulled upward to avoid being blocked by the conveyor line 1 after the fixed frames 5 on both sides are flipped. Larger workpieces can be sprayed and cleaned, so that the cleaning position can be adjusted according to I-beams of different specifications, further improving the cleaning effect and application range of the device, and ensuring the spraying quality of elevator accessories.

[0035] In order to avoid hindering the adjustment of the cleaning position, the jet pipes 6 are fixedly connected by bellows 7, and one of the jet pipes 6 is connected to the air outlet of the external fan through a hose. Through the setting of the bellows 7, when the fixed frame 5 is flipped, the bellows 7 can be driven to stretch, thereby not hindering the normal flipping of the fixed frame 5. At the same time, the jet pipes 6 are connected to each other to ensure the normal operation of the cleaning mechanism.

[0036] In order to further adjust the cleaning position according to I-beams or U-shaped frames of different sizes, the limiting mechanism includes a screw 21, the top of the fixed frame 5 is fixedly connected to the limiting slide rail 22, and a recessed groove 23 is provided near the top of the limiting slide rail 22. The outer wall of the limiting slide rail 22 and the connection between the fixed frames 5 are slidably connected to the limiting slide frame 24, and a second spring 25 is fixedly connected between the groove 23 and the limiting slide frame 24. The thrust of the second spring 25 pushes the limiting slide frame 24 to always remain at the connection between the fixed frames 5, thereby limiting the connection between the fixed frames 5 to prevent the unfolding position from flipping. The outer wall of the connecting frame 8 is fixedly connected to an adjusting frame 26, and the inner side of the adjusting frame 26 is slidably connected to an adjusting plate 27, and the screw 21 is threadedly connected to the adjusting plate 27;

[0037] The top of the limit sliding frame 24 is staggered and fixedly connected with lower conical blocks 28, wherein a pair of lower conical blocks 28 are provided with upper conical blocks 29 that fit with their inclined surfaces on the top, and a connecting rod 30 is fixedly connected between the upper conical blocks 29, the bottom of the screw 21 is rotatably connected to the top of the connecting rod 30, and a pair of guide rods 31 are fixedly connected to the top of the connecting rod 30 and penetrate the top of the adjusting plate 27. Through the setting of the guide rods 31, it can guide the connecting rod 30 when the screw 21 rotates and drives it to slide, so as to prevent the connecting rod 30 from rotating with the screw 21, thereby improving the stability of the device. Slots 32 are provided on both sides of the adjusting plate 27, and round balls 33 are slidably connected to the inner side of the slots 32. A third spring 34 is fixedly connected between the slots 32 and the round balls 33, and a plurality of limit slots 35 are provided on the inner side of the adjusting frame 26 and at positions corresponding to the round balls 33;

[0038] When the folding position of the fixed frame 5 needs to be adjusted, the adjusting plate 27 is first pushed to slide inside the adjusting frame 26, and the extrusion position of the upper conical block 29 is adjusted according to the size of the workpiece. At the same time, when the adjusting plate 27 is pushed, the ball 33 is squeezed to slide inside the slot 32 and slide out of the inner side of the limiting slot 35, and the third spring 34 is compressed at the same time. Then, when the upper conical block 29 moves to the extrusion position, the elastic force of the third spring 34 pushes the ball 33 to slide outward and snap into the inner side of the limiting slot 35, so that the adjusted position of the adjusting plate 27 can be fixed, so as to prevent the adjusting plate 27 from moving randomly and improve the stability of the device.

[0039] Then the screw rod 21 can be rotated to move downward in a spiral motion, thereby driving the connecting rod 30 and the upper conical block 29 to move downward to squeeze the inclined surface of the lower conical block 28, thereby squeezing the lower conical blocks 28 and the limiting sliding frame 24 on both sides to slide toward each other, and at the same time compressing the second spring 25, thereby releasing the position restriction on the connection between the fixed frames 5 that need to be adjusted, and then the adjustment mechanism can be controlled to start adjusting the cleaning position, and finally the reverse operation can be performed when resetting.

[0040] In order to keep the workpiece to be sprayed in the center position, a support plate 36 is fixedly connected to the front side of the first support frame 2, and a pair of guide plates 37 are fixedly connected to the bottom of the support plate 36. Through the arrangement of the pair of guide plates 37, the passing workpiece can be kept in the center position on the conveyor line 1, so that the workpiece can be replaced for cleaning and spraying, and a second servo motor 38 is fixedly connected to the top of the support plate 36, and the output end of the second servo motor 38 passes through the support plate 36 and is fixedly connected to a rotating disk 39, and the bottom sides of the rotating disk 39 are hingedly connected to the guide plate 37 with a pull rod 40, and a rectangular groove 42 is opened on the top of the support plate 36, and a rectangular rod 41 is fixedly connected to the top of the guide plate 37 and is slidably connected to the inner side of the rectangular groove 42. Through the arrangement of the rectangular groove 42 and the rectangular rod 41, the sliding of the guide plate 37 can be guided to prevent the guide plate 37 from swinging arbitrarily following the pull rod 40, thereby improving the stability of the device during adjustment.

[0041] When the position of the guide plate 37 needs to be adjusted according to the I-beam or U-shaped plate of different sizes, the second servo motor 38 is first controlled to start and drive the rotating disk 39 to rotate, and then the two pull rods 40 are pulled to rotate in opposite directions, so that the two guide plates 37 are pulled to move closer to each other through the pull rods 40, and at the same time, the rectangular rod 41 is driven to slide inside the rectangular groove 42, so as to realize the position adjustment between the guide plates 37, which is convenient for flexible adjustment according to the size of the workpiece.

[0042] The basic principles, main features and advantages of the present invention are shown and described above.
