Description

Technical Field

[0001] This utility model relates to the field of sofa manufacturing technology, and in particular to a pressing device. Background Technology

[0002] In sofa manufacturing, components made of foam typically include a base, a rectangular frame, and a cuboid backrest. These components must be glued together sequentially from bottom to top. The rectangular frame is filled with glued core blocks, and the seat cushions are then glued on top of these core blocks to form a complete sofa blank. To ensure the glue fully cures and the connections are secure, the glued sofa blanks are pressed together to ensure a tight fit between all contact surfaces.

[0003] However, existing technologies lack specialized pressing equipment for this type of sofa blank. Traditional pressing methods cannot achieve simultaneous pressing of the entire sofa blank in one go, which not only affects pressing efficiency but may also lead to poor bonding effect due to uneven force on various parts, thereby affecting the overall structural stability of the sofa.

[0004] To address this, a pressing device is proposed. Utility Model Content

Detailed Implementation

[0028] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0029] Please refer to Figures 1 to 5 As shown, an embodiment of the present invention provides a pressing device, including a conveying unit 1 and a pressing unit 2;

[0030] The pressing unit 2 includes a support base 201, a guide column 203 fixedly connected to the top of the support base 201, a top plate 202 fixedly installed on the top of the guide column 203, a pressing plate 205 for pressing the top of the sofa blank is provided between the support base 201 and the top plate 202, the pressing plate 205 is slidably installed on the guide column 203, a hydraulic cylinder 204 is fixedly installed on the top of the top plate 202, the bottom of the piston rod of the hydraulic cylinder 204 is fixedly connected to the top of the pressing plate 205, and a pressing block 206 for pressing the core block in the sofa blank is fixedly connected to the bottom of the pressing plate 205.

[0031] Among them, the conveying unit 1 used to convey the sofa blank passes through the area between the pressing plate 205 and the support base 201;

[0032] The pressing plate 205 is provided with a first anti-collapse component 3 for limiting one set of opposite sides of the sofa blank, and the conveying unit 1 is provided with a second anti-collapse component 4 for limiting the other set of opposite sides of the sofa blank.

[0033] By adopting the above technical solution, the conveying unit 1 conveys the sofa blank to the pressing area between the pressing plate 205 and the support base 201; the hydraulic cylinder 204 drives the piston rod to extend and retract, causing the pressing plate 205 to slide up and down along the guide column 203, and the pressing plate 205 to press the top of the sofa blank as a whole, while the pressing block 206 presses the core block in the sofa blank in a targeted manner, so as to achieve simultaneous pressing of multiple parts; during the pressing process, the first anti-collapse component 3 limits one set of opposite sides of the sofa blank, and the second anti-collapse component 4 limits the other set of opposite sides to prevent the sofa blank from collapsing and deforming under pressure.

[0034] In this embodiment, the conveying unit 1 includes a support frame 101, on which a conveyor belt 102 is rotatably mounted via a transmission roller, and a motor 103 for driving the conveyor belt 102 to rotate is mounted on one side of the support frame 101.

[0035] By adopting the above technical solution, the motor 103 provides power, which drives the conveyor belt 102 to rotate on the support frame 101 through the transmission roller. The sofa blank is placed on the surface of the conveyor belt 102. The rotation of the conveyor belt 102 realizes the conveying and positioning of the sofa blank in the pressing area, and completes the material transfer before and after pressing.

[0036] In this embodiment, the first anti-collapse component 3 includes two movable seats 302. The two movable seats 302 are slidably installed at the top ends of the pressing plate 205. The movable seats 302 are provided with insertion holes, and connecting posts 303 are slidably inserted into the insertion holes. The top of the pressing plate 205 is provided with a limiting sliding hole 2051. The lower end of the connecting post 303 slides through the limiting sliding hole 2051 and is fixedly connected to a first limiting plate 304. The top of the pressing plate 205 is fixedly installed with a first cylinder 301 corresponding to the movable seats 302. The piston rod end of the first cylinder 301 is fixedly connected to one side of the movable seat 302.

[0037] By adopting the above technical solution, the first cylinder 301 drives the piston rod to extend and retract, causing the movable seat 302 to slide on the pressing plate 205. The movable seat 302 drives the first limiting plate 304 to move synchronously through the connecting column 303, so that the two first limiting plates 304 fit against a set of opposite sides of the sofa blank. When the pressing plate 205 descends to press, the connecting column 303 can slide along the insertion hole of the movable seat 302, effectively avoiding the phenomenon that the pressing plate 205 cannot continue to move down after the first limiting plate 304 contacts the conveyor belt 102.

[0038] In this embodiment, an anti-detachment plate 305 is fixedly connected to the top of the connecting column 303.

[0039] By adopting the above technical solution, the anti-detachment plate 305 is located at the top of the connecting column 303. When the connecting column 303 slides along the insertion hole of the movable seat 302, the anti-detachment plate 305 can contact the top of the movable seat 302, limiting the downward sliding distance of the connecting column 303, preventing the connecting column 303 from detaching from the insertion hole of the movable seat 302, and ensuring the structural stability of the first anti-collapse component 3.

[0040] In this embodiment, a slide rail 306 is fixedly connected to the top of the pressing plate 205, and a concave groove is provided at the bottom of the movable seat 302. The movable seat 302 is slidably mounted on the slide rail 306 through the concave groove.

[0041] By adopting the above technical solution, the movable seat 302 cooperates with the slide rail 306 on the top of the pressing plate 205 through the concave slide groove at the bottom. When the first cylinder 301 drives the movable seat 302 to move, the slide rail 306 provides guidance for the movable seat 302, ensuring that the movable seat 302 slides smoothly along a straight line, avoiding the first limiting plate 304 from shifting, and ensuring accurate positioning of the side of the sofa blank.

[0042] In this embodiment, the second anti-collapse component 4 includes a second cylinder 401. There are two second cylinders 401, which are respectively installed on the bottom sides of the support frame 101. The piston rod end of the second cylinder 401 is fixedly connected to an inverted L-shaped plate 402, and the upper end of the inverted L-shaped plate 402 is fixedly connected to a second limiting plate 403.

[0043] By adopting the above technical solution, the second cylinder 401 drives the piston rod to extend and retract, causing the inverted L-shaped plate 402 to move on both sides of the support frame 101. The inverted L-shaped plate 402 drives the second limiting plate 403 to move closer to or away from the sofa blank in sync. When the sofa blank enters the pressing area, the two second limiting plates 403 are attached to another set of opposite sides of the sofa blank, limiting the sides during the pressing process to prevent them from collapsing and deforming.

[0044] In this embodiment, a guide sleeve 404 is fixedly connected to the bottom of the support frame 101, and a guide rod 405 is fixedly connected to the lower end of the inverted L-shaped plate 402. The guide rod 405 is slidably inserted into the guide sleeve 404.

[0045] By adopting the above technical solution, when the second cylinder 401 drives the inverted L-shaped plate 402 to move, the guide rod 405 at the lower end of the inverted L-shaped plate 402 slides along the guide sleeve 404 at the bottom of the support frame 101. The cooperation between the guide sleeve 404 and the guide rod 405 provides motion guidance for the inverted L-shaped plate 402, ensuring that the second limiting plate 403 moves smoothly along a straight line, thereby improving the stability and accuracy of limiting the side of the sofa blank.

[0046] The overall operation process of this pressing device is as follows:

[0047] 1. Initial preparation stage

[0048] The device is in its initial state: the pressing plate 205 is located at the upper end of the guide column 203 under the drive of the hydraulic cylinder 204, with sufficient space between it and the support base 201; the two first limiting plates 304 of the first anti-collapse component 3 are in an open state with a distance greater than the width of the sofa blank, and the two second limiting plates 403 of the second anti-collapse component 4 are also in an open state with a distance greater than the length of the sofa blank; the conveyor belt 102 is in a stationary state.

[0049] 2. Blank Placement and Conveying

[0050] The operator places the bonded sofa blank onto the conveyor belt 102 of the conveying unit 1, ensuring the blank is positioned correctly. The motor 103 is started, driving the conveyor belt 102 to rotate via the transmission rollers, transporting the sofa blank towards the pressing area. When the blank reaches directly below the pressing area, the motor 103 stops, and the conveyor belt 102 comes to a standstill, completing the blank positioning.

[0051] 3. Anti-collapse limit action

[0052] When hydraulic cylinder 204 is activated, its piston rod extends downward, causing the pressing plate 205 to slide vertically downward along guide post 203:

[0053] When the bottom of the pressing plate 205 contacts the top of the sofa blank, the piston rod of the hydraulic cylinder 204 stops moving.

[0054] The first anti-collapse component 3 operates as follows: two first cylinders 301 are activated, their piston rods retract, pushing the movable seat 302 to slide along the slide rail 306 at the top of the pressing plate 205 toward the blank; the movable seat 302 drives the first limiting plate 304 to move synchronously through the connecting column 303 until the two first limiting plates 304 are in contact with one of the opposite sides of the sofa blank, so that the lateral limiting anti-detachment plate 305 ensures that the connecting column 303 does not detach from the movable seat 302.

[0055] The second anti-collapse component 4 operates as follows: the two second cylinders 401 are activated, their piston rods retract, pushing the inverted L-shaped plate 402 to move towards the blank; the inverted L-shaped plate 402 drives the second limiting plate 403 to move synchronously until the two second limiting plates 403 are in contact with the other set of opposite sides of the sofa blank, thus achieving longitudinal limiting.

[0056] 4. Pressing and cooperating

[0057] The piston rod of the hydraulic cylinder 204 continues to extend, and the pressing plate 205 applies downward pressure to the entire blank to ensure that the base, rectangular frame, and shaped backrest are tightly fitted together.

[0058] At the same time, the pressing block 206 at the bottom of the pressing plate 205 is precisely aligned with the core block in the sofa blank, and targeted pressure is applied to the core block to ensure that the core block is firmly bonded to the surrounding structure and the seat cushion above.

[0059] During the pressing process, the first limiting plate 304 and the second limiting plate 403 always keep the blank side in place to prevent the blank from collapsing under pressure.

[0060] 5. Resetting and unloading

[0061] After pressing for a preset time, the piston rod of hydraulic cylinder 204 retracts, driving pressing plate 205 and pressing block 206 to reset upward along guide post 203; then, the piston rods of first cylinder 301 and second cylinder 401 extend, driving first limit plate 304 and second limit plate 403 to reset to the open state; finally, motor 103 starts again, and conveyor belt 102 sends the pressed sofa blank out of the pressing area, completing one pressing operation cycle, and the device waits for the next operation.

[0062] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments.
