Abstract
Description
Technical Field
[0001] This utility model relates to the field of upholstered furniture processing technology, specifically a feeding device for upholstered furniture processing. Background Technology
[0002] Upholstered furniture primarily refers to furniture made mainly of foam and fabric. The manufacturing process of upholstered furniture relies heavily on handcraftsmanship, with main steps including nailing the inner frame, applying the base fabric, attaching the foam, cutting, sewing the outer cover, and finally, upholstering. Examples include sofas and beds. Upholstered furniture is a type of furniture that includes sofas and beds made of casual fabric, genuine leather, imitation leather, or a combination of leather and fabric.
[0003] In the manufacturing process of upholstered furniture, wood raw materials such as pine, birch, and oak are usually used to make the main structure of products such as sofa frames and bed frames. During transportation, the wood boards are usually stacked on top of the feeding device. However, the stacking height of the wood boards is relatively high, and the vibration and bumps during the operation of the feeding device can easily exceed the critical overturning moment due to the inertial force generated by the transportation vibration. This can cause the upper layers of boards to slip and tip over, posing a risk of goods falling. At the same time, it increases the cost of secondary sorting, requiring workers to re-sort and adjust the stacking state, thereby reducing work efficiency. Furthermore, after the entire feeding process is completed, workers still need to move the stacked wood boards out of the feeding device one by one, increasing the manpower requirements and making the transportation process cumbersome and inefficient.
[0004] Therefore, those skilled in the art have provided a feeding device for processing upholstered furniture to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to provide a feeding device for processing upholstered furniture, so as to solve the problems mentioned in the background art, such as the inconvenience of feeding and the shaking of wooden boards during transportation.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A feeding device for processing upholstered furniture includes a feeding cart, an adjusting mechanism, and a limiting mechanism. Two sets of adjusting seats are fixedly connected to one end of the upper surface of the feeding cart. A stacking plate is rotatably connected between the two sets of adjusting seats. A fixed column is fixedly connected to the center of the upper surface of the stacking plate. A threaded rod is rotatably connected inside the fixed column. A servo motor is fixedly connected to the top of the fixed column. The power output end of the servo motor passes through the fixed column and is fixedly connected to the threaded rod. A threaded sleeve is threadedly connected to the outer wall of the threaded rod. The threaded sleeve is slidably engaged with the inner wall of the fixed column. A limiting mechanism is provided at the upper end of the threaded sleeve.
[0008] As a further embodiment of this utility model: two sets of sliders are slidably connected to the bottom end of the stacking plate away from the adjusting seat. The bottom ends of the two sets of sliders are fixedly connected to hinge seats. A hinge rod is rotatably connected inside the hinge seat. A hinge sleeve is rotatably connected to the outer wall of the hinge rod.
[0009] As a further improvement of this utility model: two sets of electric push rods are fixedly connected to the end of the upper surface of the feeding cart away from the adjusting seat, and the electric push rods are all fixedly connected to the adjacent hinge sleeves.
[0010] As a further embodiment of this utility model: both the left and right ends of the threaded sleeve are fixedly connected to a first extension post, and both the first extension posts are rotatably connected to a bidirectional lead screw. The outer walls of both the left and right ends of the bidirectional lead screw are threadedly connected to a first limiting plate, and the first limiting plate is slidably engaged with the inner wall of the first extension post. The end of the first extension post away from the fixed post is rotatably connected to a knob, and the power end of the knob passes through the fixed post and is fixedly connected to the bidirectional lead screw.
[0011] As a further embodiment of this utility model: a second extension column is fixedly connected to both side walls of the first extension column, an adjustment groove is provided in the second extension column, and multiple sets of limiting holes are provided on the left and right sides of the upper end face of the second extension column, and the multiple sets of limiting holes are arranged at equal intervals.
[0012] As a further embodiment of this utility model: a second limiting plate is slidably engaged in the adjusting groove, and an installation plate is fixedly connected to the top of the second limiting plate. Limiting holes are opened at both ends of the installation plate. Insert rods are movably engaged at the overlapping points of the limiting holes of the installation plate and the limiting holes at the upper ends of the second extension column. Connecting rods are fixedly connected to the upper ends of the two sets of insert rods. Pull blocks are fixedly connected to the upper ends of the connecting rods. Return springs are sleeved and connected to the outer walls of the insert rods. One end of the return spring is fixedly connected to the installation plate, and the other end of the return spring is fixedly connected to the connecting rod.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. Because of the adjustment mechanism, the start of the electric push rod drives the stacking plate to rise and adjust the angle to form an inclined surface, which simplifies the unloading process. The staff does not need to spend a lot of manpower to move the wood. They can realize the automatic sliding of the wood by simply controlling the electric push rod, which significantly improves the unloading efficiency and reduces the labor intensity.
[0015] 2. Due to the presence of a limiting mechanism, the timber stack is constrained in three dimensions by multi-directional pressing from the top (first / second extension column), left and right sides (first limiting plate), and front and rear sides (second limiting plate). This effectively prevents the timber from shifting due to vibration, tilting, or other factors during movement, ensuring safety during transportation or processing. The synergistic effect of the pressing forces in all directions allows it to withstand greater external impacts compared to fixing in a single direction, reducing the risk of timber scattering. The first / second extension column, first limiting plate, and second limiting plate are all freely adjustable to accommodate timber boards of different sizes. Attached Figure Description

[0021] 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.
[0022] Example 1
[0023] Reference Figure 1-4This embodiment provides a feeding device for processing upholstered furniture, including a feeding cart 1, an adjusting seat 2, a stacking plate 3, an electric push rod 4, a slider 5, a hinge seat 6, a hinge rod 7, a hinge sleeve 8, a fixing column 9, a threaded rod 10, a threaded sleeve 11, a servo motor 12, a first extension column 13, a bidirectional lead screw 14, a knob 15, a first limiting plate 16, a second extension column 17, an adjusting groove 18, a second limiting plate 19, a mounting plate 20, a limiting hole 21, an insert rod 22, a return spring 23, a connecting rod 24, and a pull block 25; Two sets of adjusting seats 2 are fixedly connected to one end of the upper surface of the feeding car 1. A stacking plate 3 is rotatably connected between the two sets of adjusting seats 2. A fixed column 6 is fixedly connected to the center of the upper surface of the stacking plate 3. A threaded rod 10 is rotatably connected inside the fixed column 6. A servo motor 12 is fixedly connected to the top of the fixed column 6. The power output end of the servo motor 12 passes through the fixed column 6 and is fixedly connected to the threaded rod 10. A threaded sleeve 11 is threadedly connected to the outer wall of the threaded rod 10. The threaded sleeve 11 is slidably engaged with the inner wall of the fixed column 6. A limit mechanism is provided at the upper end of the threaded sleeve 11.
[0024] Example 2
[0025] Reference Figure 1 , 2 This embodiment is based on the previous embodiment, but differs from the previous embodiment in that two sets of sliders 5 are slidably connected to the bottom end of the stacking plate 3 away from the adjusting seat 2. The bottom ends of the two sets of sliders 5 are fixedly connected to hinge seats 6. Hinges 7 are rotatably connected inside the hinge seats 6. Hinges 8 are rotatably connected to the outer wall of the hinges 7. Two sets of electric push rods 4 are fixedly connected to the upper end of the feeding car 1 away from the adjusting seat 6. The electric push rods 4 are fixedly connected to the adjacent hinge sleeves 8.
[0026] When unloading is required, start the electric push rod 4. The electric push rod 4 will lift upward and drive the hinge sleeve 8 and the hinge seat 6 to lift upward, so that the stacking plate 3 moves synchronously. According to the rotational connection between the other end of the stacking plate 3 and the two sets of adjustment seats 2, the angle of the stacking plate 3 can be adjusted to form an inclined angle, which makes it easier for the staff to unload the material.
[0027] It should be added that the hinge effect of the hinge sleeve 8 and the hinge rod 7 can prevent jamming during the lifting process of the electric push rod 4 driving the stack plate 3 to move.
[0028] It should be added that the hinge seat 6 is slidably connected to the stacking plate 3 via the slider 5, which can prevent jamming during the movement of the stacking plate 3 driven by the electric push rod 4.
[0029] Example 3
[0030] Reference Figure 1 , 34. This embodiment is based on the previous embodiment, but differs in that: both ends of the threaded sleeve 11 are fixedly connected to a first extension post 17, and both ends of the first extension post 17 are rotatably connected to a bidirectional lead screw 14. Both ends of the bidirectional lead screw 14 are threadedly connected to the outer walls of a first limiting plate 16, and the first limiting plate 16 is slidably engaged with the inner wall of the first extension post 17. A knob 15 is rotatably connected to the end of the first extension post 17 away from the fixed post 9. The power end of the knob 15 passes through the fixed post 9 and is fixedly connected to the bidirectional lead screw 14. Both ends of the first extension post 17 are fixedly connected to a second extension post 17, and both ends of the second extension post 17 have an adjustment groove 18. The upper end of the second extension post 17... Multiple sets of limiting holes 21 are provided on both the left and right sides of the surface. The multiple sets of limiting holes 21 are arranged at equal intervals. A second limiting plate 19 is slidably engaged in the adjustment groove 18. A mounting plate 20 is fixedly connected to the top 1 of the second limiting plate 19. Limiting holes 21 are provided on both the left and right ends of the mounting plate 20. Insert rods 22 are movably engaged at the overlapping points of the limiting holes 21 of the mounting plate 20 and the limiting holes 21 at the upper end of the second extension column 17. Connecting rods 24 are fixedly connected to the upper ends of the two sets of insert rods 22. Pull blocks 25 are fixedly connected to the upper ends of the connecting rods 24. A return spring 23 is sleeved and connected to the outer wall of the insert rod 22. One end of the return spring 23 is fixedly connected to the mounting plate 20, and the other end of the return spring 23 is fixedly connected to the connecting rod 24.
[0031] The same batch of wooden boards are stacked sequentially on the left and right ends of the stacking plate 3 (both sides of the fixed column 9), and the height of the stacked wood on both sides is consistent. After stacking, the servo motor 12 is started. The servo motor 12 drives the threaded rod 10 to rotate. The threaded rod 10 drives the threaded sleeve 11 on the outer wall to move vertically horizontally (the threaded sleeve 11 is limited by the fixed column 9). This drives the first extension column 13 at the left and right ends of the threaded sleeve 11 and the various components at the upper end to press down vertically horizontally in sync until the lower end face of the first extension column 13 and the second extension column 17 abuts against and presses against the top of the wood stack.
[0032] After pressing the top, rotate the knob 15 on the side wall of the first extension column 13. The knob 15 rotates and drives the bidirectional lead screw 14 to rotate. The rotation of the bidirectional lead screw 14 drives the first limiting plates 16 connected by threads at both ends to move laterally horizontally. Through the positive and negative thread connection of the bidirectional lead screw 14, both sets of first limiting plates 16 move laterally horizontally towards one end of the wood pile until the two sets of first limiting plates 16 abut against and press against the outer walls of the left and right sides of the wood pile.
[0033] Pull the lever 25, which will move the connecting rod 24 at the bottom and the two sets of insert rods 22 upward, moving them out of the limiting hole 21 of the second extension column 17. This will unlock the mounting plate 20 and the second limiting plate 19. Pull the mounting plate 20 and the second limiting plate 19 into the adjusting groove 18 of the second extension column 17 until they abut against and press against the outer walls of the front and rear sides of the timber stack. After pressing, release the lever 25, and the return spring 23 on the outer wall of the insert rod 22 will automatically reset, causing the insert rod 22, the connecting rod 24 and the locking block to automatically reset, and allowing the insert rod 22 to insert into the bottom perpendicular limiting hole 21, thus completing the relocking.
[0034] It should be added that by pressing down the top surface and all side walls of the timber pile, it is possible to effectively prevent the timber pile from shifting during movement.
[0035] It should be added that when the lower end faces of the first extension post 13 and the second extension post 17 abut against and press against the top of the timber pile, the positions of the two sets of first limiting plates 16 and the two sets of second limiting plates 19 are the initial positions.
[0036] It should be added that the initial position of the first limiting plate 16 and the two sets of second limiting plates 19 is the side of the first extension post 13 and the second extension post 17 furthest away from the timber pile.
[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
