Abstract
Description
Technical Field
[0001] This utility model relates to the field of pressure strip feeding technology, specifically an automatic feeding device for decorative panel pressure strips. Background Technology
[0002] Against the backdrop of the rapid development of the building decoration and furniture manufacturing industry, decorative panels, as a core material that combines aesthetics and functionality, are seeing their application scenarios continuously expand, and the requirements for the processing precision of decorative panels are also significantly increasing. As a key component for the assembly and edge finishing of decorative panels, the processing quality of decorative panel molding strips directly affects the overall splicing effect and service life of the decorative panels. During the processing of decorative panel molding strips, multiple processes such as conveying, positioning, drilling, and cutting are usually required.
[0003] Existing feeding methods for decorative panel strips use fixed tracks or single guide structures. In actual feeding processes, due to differences in the materials of the decorative panel strips (such as wood, plastic, metal, etc.) and unavoidable minor dimensional deviations during production, fixed tracks or single guide structures cannot provide a stable and suitable limiting effect on both sides of the strip, which can easily lead to unilateral deviation of the strip during conveying.
[0004] Existing decorative panel molding strips lack effective cleaning of surface debris during processing. In the early processing of molding strips (such as cutting and sanding), impurities such as wood chips, plastic scraps, or metal powder easily adhere to their surface. If these debris are not cleaned in time, they will fill the contact surface between the molding strip and the clamp when the molding strip is held by the positioning fixture, forming a "micro-gap". This "micro-gap" will cause the positioning fixture to reduce the clamping and positioning accuracy of the molding strip, further aggravating the problems of hole position deviation and cutting dimension deviation.
[0005] Patent CN208648057U discloses an automatic feeding machine for pressing strips. By having multiple material cylinders, a large number of pressing strips can be placed in a single automatic feeding machine, and it can cooperate with a robot to realize automatic feeding of pressing strips.
[0006] However, this patent has the following drawbacks: during the feeding and conveying process of the decorative panel strip, the feeding machine does not effectively treat the debris (such as wood chips, plastic fragments, metal powder, etc. generated in the previous processing) attached to the surface of the strip; after these residual debris enter the next processing station with the strip, they will directly interfere with the precise operation of subsequent processes and affect the processing quality and precision of the decorative panel strip. Utility Model Content
[0007] To address the technical problems in existing technologies, such as the tendency for unilateral deviation during the feeding of decorative panel strips and the easy adhesion of impurities such as wood chips, plastic scraps, and metal powder to the surface of the strips, coupled with the lack of effective cleaning methods, this utility model provides an automatic feeding device for decorative panel strips.
[0008] The objective of this utility model can be achieved through the following technical solutions: An automatic feeding device for decorative panel strips includes a support frame and a horizontal plate mounted on the upper part of the support frame. Vertical plates are fixedly connected to the upper surface of the horizontal plate. A double-acting screw and a guide rod are rotatably connected between the symmetrically arranged vertical plates. Adjusting nuts are threaded onto the double-acting screw and the guide rod and are symmetrically arranged. A connecting rod is fixedly connected to the lower surface of the adjusting nut. A clamping plate is fixedly connected to the lower surface of the connecting rod. A first limiting groove is opened at the bottom of the connecting rod. A limiting rod is provided in the first limiting groove. A first spring is provided on the outside of the limiting rod. A first sweeping rod and a second sweeping rod are provided in the first limiting groove. A second limiting groove is provided at the end of the second sweeping rod near the first sweeping rod. A second spring is provided in the second limiting groove. One end of the second spring is connected to the first sweeping rod, and the other end of the second spring is connected to the second sweeping rod.
[0009] Furthermore, the inside of the horizontal plate has a slot, and a worm is installed in the slot of one side of the horizontal plate. Multiple sets of worm wheels are meshed and connected above the worm, and the worm wheels are evenly distributed in multiple sets along the horizontal direction.
[0010] Furthermore, the horizontal plate is equipped with a rotating shaft on each of its opposite sides, and a rotating roller is fixedly connected to each of the opposite ends of the rotating shaft. The rotating shaft on one side passes through the side wall of the horizontal plate and is connected to a worm gear, while the rotating shaft on the other side is rotatably connected to the side wall of the horizontal plate.
[0011] Furthermore, the guide rod and the bidirectional lead screw are arranged parallel to each other in the horizontal direction, the clamping plates are symmetrically arranged, the first limiting groove is opened at the bottom of the connecting rod located on one side of the guide rod, and the first limiting groove is opened on the opposite side of the symmetrically arranged connecting rods.
[0012] Furthermore, one end of the limiting rod is movably connected to the inside of the connecting rod, and the other end of the limiting rod is fixedly connected to the upper surface of the first sweeping rod; one end of the first spring is fixedly connected to the upper surface of the first sweeping rod, and the other end of the first spring is fixedly connected to the side wall of the connecting rod.
[0013] Furthermore, one end of the first sweeping rod is movably connected to the first limiting groove, and the other end of the first sweeping rod is connected to the second sweeping rod.
[0014] The beneficial effects of this utility model are: This invention utilizes a second motor to drive a bidirectional lead screw to rotate. The rotation of the lead screw causes symmetrically arranged adjusting nuts to move relative to or opposite to each other. This relative or opposite movement of the adjusting nuts causes the connecting rods to move relative to or opposite to each other, which in turn causes the symmetrically arranged clamping plates to move relative to or opposite to each other. The clamping plates provide a limiting effect on both sides of the pressure strip during transport, preventing unilateral deviation. The elastic force of the first spring causes the pressure strip to exert pressure on its upper surface as it passes the bottom of the first and second sweeping rods, thus removing debris. The first spring can adapt to pressure strips of different thicknesses. Removing debris from the surface of the pressure strip reduces the "micro-gap" between the pressure strip and the positioning fixture, facilitating the reduction of hole misalignment and dimensional deviations during subsequent drilling and cutting.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-3As shown, an automatic feeding device for decorative panel strips includes a support frame 1 and a horizontal plate 101 installed on the upper part of the support frame 1, and the support frame 1 is symmetrically arranged. The support frame 1 and the horizontal plate 101 form a U-shape with the opening facing downwards. The horizontal plate 101 has a slot inside, and a worm 5 is provided in the slot on one side of the horizontal plate 101. Multiple sets of worm wheels 4 are meshed above the worm 5, and the worm wheels 4 are evenly distributed in multiple sets along the horizontal direction; this can ensure the force balance and power transmission consistency during the transmission process.
[0019] One end of the worm 5 is rotatably connected to the output end of the first motor 3, and the output end of the first motor 3 passes through the horizontal plate 101 and is fixedly connected to the worm 5; the other end of the worm 5 is rotatably connected to the inner side wall of the horizontal plate 101.
[0020] The horizontal plate 101 is rotatably provided with a rotating shaft 401 on each opposite side. A rotating roller 6 is fixedly connected to each opposite end of the rotating shaft 401. The rotating shaft 401 on one side passes through the side wall of the horizontal plate 101 and connects to the worm gear 4, so as to realize the transmission of power from the worm gear 4 to the rotating roller 6. The rotating shaft 401 on the other side is rotatably connected to the side wall of the horizontal plate 101, so as to provide stable rotational support for the rotating roller 6.
[0021] By starting the first motor 3, the driving force generated at the output end of the first motor 3 is directly transmitted to the worm 5 fixedly connected to it, causing the worm 5 to rotate stably along its own axis. Under the meshing transmission action of the worm 5, multiple sets of worm wheels 4 synchronously obtain power and rotate in the same direction. As the worm wheels 4 rotate, the rotating shaft 401 fixedly connected to the worm wheels 4 is also synchronously driven and rotates in the same direction around its own axis. The other end of the rotating shaft 401 is firmly connected to the rotating roller 6. Therefore, the rotation of the rotating shaft 401 will directly drive multiple rotating rollers 6 to rotate in the same direction.
[0022] As the roller 6 rotates continuously, the friction between its outer surface and the decorative panel strip will smoothly convey the decorative panel strip, uniformly transferring the decorative panel strip placed on the roller 6 from the current processing station to the next processing station, thus realizing the automatic feeding of the decorative panel strip.
[0023] Please see Figure 1 and Figure 4 As shown, vertical plates 2 are fixedly connected to the upper surface of the horizontal plate 101. A bidirectional lead screw 7 is rotatably connected between the symmetrically arranged vertical plates 2. One end of the bidirectional lead screw 7 is connected to the output end of the second motor 12. The output end of the second motor 12 passes through the vertical plate 2 and is fixedly connected to one end of the bidirectional lead screw 7.
[0024] Guide rods are rotatably connected between the symmetrically arranged vertical plates 2. The guide rods and the bidirectional lead screw 7 are arranged parallel to each other in the horizontal direction. Adjusting nuts 8 are threadedly connected to both the bidirectional lead screw 7 and the guide rods. Connecting rods 10 are fixedly provided on the lower surface of the adjusting nuts 8. Clamping plates 11 are fixedly connected to the lower surface of the connecting rods 10. The clamping plates 11 are symmetrically arranged and are used to prevent the decorative panel strip from shifting to one side during the conveying process.
[0025] By starting the second motor 12, the second motor 12 drives the bidirectional lead screw 7 to rotate. The rotation of the bidirectional lead screw 7 causes the symmetrically arranged adjusting nuts 8 to move relative to or opposite to each other. The relative or opposite movement of the adjusting nuts 8 causes the connecting rod 10 to move relative to or opposite to each other. The relative or opposite movement of the connecting rod 10 causes the symmetrically arranged clamping plates 11 to move relative to or opposite to each other. During the conveying process, the decorative panel strip can limit the two sides of the decorative panel strip, so that the decorative panel strip does not deviate to one side during the conveying process.
[0026] A first limiting groove 13 is provided at the bottom of the connecting rod 10 located on one side of the guide rod 9. The first limiting groove 13 is provided on the opposite side of the symmetrically arranged connecting rods 10. A limiting rod 15 is provided in the first limiting groove 13. One end of the limiting rod 15 is movably connected to the inside of the connecting rod 10, and the other end of the limiting rod 15 is fixedly connected to the upper surface of the first sweeping rod 16. A first spring 14 is provided on the outside of the limiting rod 15. One end of the first spring 14 is fixedly connected to the upper surface of the first sweeping rod 16, and the other end of the first spring 14 is fixedly connected to the side wall of the connecting rod 10. When the first spring 14 is in the maximum tension state, it will still apply a certain pressure to the thinnest pressure plate.
[0027] During the conveying process, when the decorative panel strip passes the bottom of the first sweeping bar 16 and the second sweeping bar 1601, the first sweeping bar 16 and the second sweeping bar 1601 will exert a certain pressure on the upper surface of the strip with the help of the elastic force of the first spring 14, and the first sweeping bar 16 and the second sweeping bar 1601 will remove the debris on the upper surface of the decorative panel strip; and the first spring 14 can adapt to decorative panel strips of different thicknesses.
[0028] Removing surface debris can reduce the "tiny gap" between the decorative panel strip and the positioning fixture, making it easier to reduce subsequent issues such as hole misalignment and out-of-tolerance cutting dimensions during drilling and cutting.
[0029] Please see Figure 1 and Figure 5As shown, one end of the first sweeping rod 16 is movably connected to the first limiting groove 13, and the other end of the first sweeping rod 16 is connected to the second sweeping rod 1601. The second sweeping rod 1601 is provided with a second limiting groove 1602 at the end near the first sweeping rod 16. A second spring 17 is provided in the second limiting groove 1602. One end of the second spring 17 is connected to the first sweeping rod 16, and the other end of the second spring 17 is connected to the second sweeping rod 1601.
[0030] When the symmetrically arranged clamping plates 11 move in opposite or relative directions, under the elastic driving force of the second spring 17, the first sweeping rod 16 can be adaptively stretched or contracted along the second limiting groove 1602 of the second sweeping rod 1601; this allows the relative position of the first sweeping rod 16 and the second sweeping rod 1601 to be adjusted synchronously with the movement of the clamping plates 11, thereby flexibly adapting to the opening and closing movements of the symmetrical clamping plates 11, ensuring that the sweeping rod can still maintain a stable cleaning function on the decorative panel strip when the position of the clamping plates 11 changes.
