Description

Technical Field

[0001] This utility model relates to the field of lampshade feeding technology, and in particular to an automatic lampshade feeding device. Background Technology

[0002] In traditional lampshade production, the unloading process after cutting often relies heavily on manual labor. Workers need to manually pick up scattered lampshades from beside the cutting equipment and then carry them to a designated collection area. Because the speed of manual unloading is limited by the workers' physical strength, skill level, and number of workers, it is difficult to meet the requirements of high-speed, continuous operation in modern production lines, often becoming a bottleneck in the entire production process. Secondly, the labor intensity is high. Furthermore, directly picking up the lampshades after cutting, before they have left the cutting area, easily leads to operational errors, causing accidental injury to the lampshade and cutting tool. Finally, workers need to bend over for long periods, repeatedly grabbing and carrying items, which easily leads to fatigue and work-related injuries. The working environment is relatively monotonous and highly repetitive, therefore, an automatic lampshade unloading device is needed. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-4 An automatic lampshade unloading device includes a unloading frame 1, with a feed inlet 2 at the right end of the unloading frame 1. The feed end of the feed inlet 2 is connected to the conveying end of the lampshade cutting and conveying. After the lampshade is cut, it enters the interior of the unloading frame 1 through the feed inlet 2 via a conveyor belt. An automatic unloading mechanism 3 is set inside the unloading frame 1 to realize the automatic unloading action of the cut lampshade. An insertion groove 9 is opened at the receiving point of the unloading frame 1. A receiving frame 10 is slidably inserted into the inner wall of the insertion groove 9. A universal wheel is also provided at the bottom of the receiving frame 10.

[0020] A support plate 4 is fixedly installed on the inner wall of the feeding frame 1. The support plate 4 is located at the left end of the feed inlet 2. A sliding groove 5 is opened on the top of the support plate 4, and a sliding rod 6 is slidably inserted into the inner wall of the sliding groove 5.

[0021] Specifically, the support plate 4 is set up so that the cut lampshade enters the unloading frame 1 through the conveyor and is supported by the support plate 4. The slide groove 5 opened on the surface of the support plate 4 facilitates the sliding rod 6 to slide inside the slide groove 5 and adjust the distance between the slide rod 6 and the lampshade.

[0022] The bottom of the slide rod 6 is threadedly connected to a limit locking plate 7, which is located at the bottom of the support plate 4 and is locked in place by screws. The top of the slide rod 6 is rotatably connected to an auxiliary wheel 8 via a bearing.

[0023] Specifically, after the slide bar 6 is adjusted to the desired position, it is firmly fixed in a specific position within the slide groove 5 by a threaded locking plate 7 and screws. This ensures that the adjusted precise position can be reliably maintained and will not move arbitrarily due to vibration or other forces during operation; the auxiliary wheel 8 can gently guide the lampshade. When the lampshade is pushed or guided into the lower material frame 1 after being cut by the cutting mechanism, the rotation of the auxiliary wheel 8 allows the lampshade to move more smoothly and reduces resistance.

[0024] The automatic feeding mechanism 3 includes a feeding plate 31. One end of the inner wall of the feeding frame 1 is hinged to one end of the feeding plate 31. The feeding plate 31 is located on one side of the support plate 4. A telescopic cylinder 32 is hinged to the inner wall of the feeding frame 1. The top end of the telescopic cylinder 32 is hinged to the bottom of the feeding plate 31. The feeding plate 31 can reciprocate around the axis of the hinge by the telescopic movement of the telescopic cylinder 32.

[0025] Specifically, by swinging, the material feeding plate 31 can flip the lampshade conveyed on the support plate 4 out from the top of the material feeding plate 31. This can more effectively transfer materials from the feeding area to the inside of the receiving frame 10 to achieve automatic material receiving; the movement of the telescopic cylinder 32 is controllable, and the angle, speed and timing of the swing of the material feeding plate 31 can be precisely controlled to achieve precise material feeding control.

[0026] A vertical slide plate 33 is fixedly installed at the top of one end of the feeding frame 1. An adjustment groove 34 is provided on the surface of the vertical slide plate 33. An adjustment rod 35 is slidably inserted into the inner wall of the adjustment groove 34. One end of the adjustment rod 35 is rotatably connected to an extrusion wheel 36 through a bearing. The extrusion wheel 36 is located at the top of the lampshade.

[0027] Specifically, this is implemented by setting an extrusion roller 36 at the top of the lampshade, which limits the top direction of the lampshade during transport to prevent deviation and ensure precise transport. The adjustment groove 34 can be set to adjust the limiting position according to the thickness of the lampshade, reducing limitations.

[0028] The other end of the adjusting rod 35 is threadedly connected to a sealing plate 37, which is located on one side of the vertical slide plate 33 and is locked in place by screws.

[0029] Specifically, by setting the sealing plate 37, it is possible to lock and position the adjusting rod 35 after the position is adjusted, so that the squeezing wheel 36 is prevented from tilting upward under the conveying force of the lamp cover during rolling, thus preventing the adjusting rod 35 from shifting.

[0030] An L-shaped connecting plate 38 is fixedly installed on the top left end of the feeding frame 1. A sensor 39 is fixedly installed on the top of the L-shaped connecting plate 38. The sensor 39 detects the input lampshade and sends a signal to the controller.

[0031] Specifically, sensor 39 is a photoelectric sensor that can accurately detect whether the lampshade has successfully entered the unloading position. It confirms that the cutting action during conveying has been completed and the product has been fed in. After sensor 39 detects the lampshade entering, it sends an electrical signal to the controller, such as a PLC. Upon receiving the signal, the controller determines whether to execute a cylinder action based on a pre-programmed program or logic. If the action conditions are met, the controller sends a control signal to the solenoid valve. Upon receiving the control signal, the solenoid valve switches its internal air path. The air source flows to a specific chamber of the cylinder, either the rod chamber or the rodless chamber, according to the solenoid valve's switching, while gas in the other chamber is discharged, driving the cylinder piston to move.

[0032] The automatic lampshade unloading device achieves efficient, precise, and reliable automated operation through a series of ingenious designs. The support plate 4, in conjunction with the adjustable slide bar 6 and auxiliary wheels 8, not only provides stable support for the lampshade but also allows for flexible adjustment according to its size, guiding its smooth transport and effectively preventing deviation and accumulation, thus reducing the risk of damage. The core unloading plate 31, combined with the telescopic cylinder 32, achieves active and efficient transfer of the lampshade through precisely controlled swinging motion, avoiding the clogging problems that may occur with traditional methods and ensuring production cycle time. The adjustable extrusion wheel 36 on the vertical slide plate 33 further limits and tidies up the top of the lampshade, and locks it in place with the sealing plate 37 to ensure positional stability. The addition of the sensor 39 and controller gives the entire system "intelligent" characteristics, enabling real-time monitoring of the lampshade transport status and precise triggering of the unloading action based on signals, achieving closed-loop control of the production process. These synergistic designs significantly improve production efficiency, product quality, and automation level, reduce labor costs and labor intensity, and enhance the adaptability and reliability of the equipment.

[0033] Working principle: First, the cut lampshades enter from the feed port 2 at the right end of the unloading frame 1 via the conveyor mechanism and fall onto the support plate 4. The auxiliary wheels 8 on the support plate 4 gently guide the lampshades to align them neatly.

[0034] At the top of the feeding frame 1, sensor 39 monitors in real time. When a new lampshade enters its detection range, sensor 39 sends a signal to the controller to confirm the arrival of the material.

[0035] After receiving the signal, the controller will determine whether to perform the unloading action according to the preset program. When the conditions are met, the controller sends a command to the solenoid valve of the telescopic cylinder 32.

[0036] The solenoid valve switches the air path, allowing compressed air to enter either the rod-side or rodless-side chamber of the telescopic cylinder 32, pushing the piston to extend or retract. The piston's movement drives the feed plate 31, which is hinged to it, to swing downwards around the hinge axis.

[0037] When the feeding plate 31 swings, the lampshade on the support plate 4 tilts into the receiving frame 10. Then, the controller controls the solenoid valve to reverse, causing the cylinder to extend and the feeding plate 31 to return to its original position, ready for the next feeding cycle. When there are too many lampshades stored in the receiving frame 10, the receiving frame 10 can be moved out of the feeding frame 1 to be replaced with a new receiving frame 10 to continue receiving materials. The receiving frame 10 that has received materials moves to the next process to wait for operation.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
