Description

Technical Field

[0001] This utility model relates to the technical field of table lifting devices, and in particular to a table lifting device for a fabric lining machine. Background Technology

[0002] The main function of a fabric stacking machine is to neatly stack different types of fabrics to facilitate subsequent production and processing. The position of the fabric stacking knife remains unchanged. For each layer of fabric stacked, the stacking platform (where the fabric is piled) is lowered to the required height according to the type and thickness of the fabric.

[0003] Chinese utility model patent CN203411152U discloses an automatic lifting system for a fabric lining machine platform, comprising a fabric lining machine platform, an AC motor, a reducer, platform lifting wheels, a first lifting chain support roller, a second lifting chain support roller, and a platform lifting shaft. Both sides of the fabric lining machine platform are equipped with pulleys mounted on guide rails. The AC motor is controlled by a frequency converter and connected to a worm gear reducer via a pulley pair. The worm gear reducer is connected to the platform lifting wheels via a sprocket pair. The platform lifting wheels are mounted on the platform lifting shaft. A first lifting chain is provided between the platform lifting wheels and the first lifting chain support roller, and the first lifting chain is connected to a pulley on one side of the fabric lining machine platform.

[0004] The existing lifting structure is a chain-driven structure, which connects the chain directly to the platform. The main load-bearing component is the chain. Especially when the limiting components or structures at both ends of the platform malfunction, the platform will swing, resulting in poor overall stability and mechanical strength. Utility Model Content

[0005] To solve the above problems, this utility model provides a table lifting device for a fabric lining machine.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a table lifting device for a fabric stacking machine, comprising two side plates, a mounting base fixed between the two side plates, a lifting table between the two mounting bases, two first lifting rods rotatably mounted on the mounting base and symmetrically arranged about the center of the lifting table, and a second lifting rod rotatably mounted on the lifting table. The first and second lifting rods are intersected and rotatably connected, the number of the second lifting rods is equal to the number of the first lifting rods and their positions correspond one-to-one, the end of the first lifting rod away from the mounting base is disposed together with the lifting table, a sliding seat is slidably disposed on the mounting base, the end of the second lifting rod away from the lifting table is rotatably disposed on the sliding seat, and a displacement component for driving the sliding seat to move is disposed on the side plate.

[0007] By adopting the above technical solution, the sliding seat is moved by the displacement component, causing the lower end of the second lifting rod to flip toward the lower end of the first lifting rod, while the upper end of the first lifting rod moves toward the upper end of the second lifting rod. This causes the lifting platform to rise or fall, thereby changing the height of the fabric. This product removes the chain traction structure of the existing technology and replaces it with a scissor structure in which the first and second lifting rods are intersected, improving the overall structural stability and strength of the device.

[0008] Furthermore, the displacement assembly includes a displacement motor fixed to one of the side plates, a reducer connected to the output end of the displacement motor, a coupling connected to the output end of the reducer, and a lead screw fixed to the coupling and coaxially arranged with the coupling. The lead screw passes through the sliding seat and is threadedly connected.

[0009] By adopting the above technical solution, after the displacement motor starts working, the reducer reduces the speed of the output end of the displacement motor and transmits the speed to the coupling through the output end of the reducer, thereby causing the lead screw to rotate. Since the lead screw is threadedly connected to the sliding seat, the sliding seat can move. By reducing the speed of the displacement motor, the load on the displacement motor is reduced, thereby reducing the heat generated by the motor due to long-term operation and improving the service life and accuracy of the motor.

[0010] Furthermore, a conveying mechanism is provided on the lifting platform. The conveying mechanism includes a conveying component, which includes a main synchronous pulley rotatably mounted on the lifting platform, a driven synchronous pulley rotatably mounted on the lifting platform, and a synchronous belt sleeved on the lifting platform. The synchronous belt meshes with both the main synchronous pulley and the driven synchronous pulley. The conveying mechanism also includes a rotating component for driving the main synchronous pulley to rotate.

[0011] By adopting the above technical solution, the main synchronous pulley is driven to rotate by the rotating component, thereby causing the synchronous belt meshing with the main synchronous pulley and the slave synchronous pulley meshing with the synchronous belt to rotate, which facilitates the removal or storage of fabric from the lifting platform.

[0012] Furthermore, the rotating assembly includes a rotating motor fixed to the lifting platform, a main sprocket fixedly sleeved on the output end of the rotating motor, a driven sprocket fixedly sleeved on the main synchronous pulley, and a chain for connecting the main sprocket and the driven sprocket, all of which mesh with the main sprocket and the driven sprocket.

[0013] By adopting the above technical solution, after the rotating motor is working, the main sprocket connected to the output end of the rotating motor, the chain connected to the main sprocket, the driven sprocket meshing with the chain, and the main synchronous wheel fixed to the driven sprocket all rotate, thereby ensuring the normal removal or storage of the fabric.

[0014] Furthermore, the sliding seat is provided with a connecting assembly, which includes a connecting column rotatably mounted on the sliding seat, a roller disposed on the connecting column, and a limiting plate fixed on the mounting base and slidingly cooperating with the roller. The connecting column passes through the end of the second lifting rod away from the lifting platform and is rotatably connected. The number of sets of the connecting assembly is equal to the number of the second lifting rods and their positions correspond one-to-one.

[0015] By adopting the above technical solution, the roller will slide within the limiting plate during the sliding process of the lower end of the second lifting rod, which improves the stability of the movement of the second lifting rod.

[0016] Furthermore, the roller is rotatably connected to the connecting column, and the roller and the connecting column are coaxially arranged.

[0017] By adopting the above technical solution, the roller is rotatably connected to the connecting column, which reduces the friction between the roller and the limiting plate.

[0018] Furthermore, the surface of the synchronous belt is provided with grooves of a wave-shaped structure.

[0019] By adopting the above technical solution, the friction of the fabric on the synchronous belt is increased.

[0020] Furthermore, a moving mechanism is jointly provided on the side plate and the lifting platform. The moving mechanism includes a limiting component, which includes a fixed frame disposed between the two side plates. The upper end of the second lifting rod is rotatably mounted on the bottom of the fixed frame, and a connecting block is rotatably mounted on the upper end of the first lifting rod. The connecting block is slidably engaged with the bottom of the fixed frame. The lifting platform is slidably disposed on the fixed frame. The limiting component also includes a sliding block fixed to the lifting platform and a limiting frame fixed to the fixed frame. The limiting frame passes through the sliding block and is slidably engaged. The moving mechanism also includes a driving component for driving the lifting platform to move.

[0021] By adopting the above technical solution, the driving component drives the lifting platform to move, which in turn moves both the synchronous belt connected to the lifting platform and the sliding block connected to the lifting platform. This allows for adjustment of the horizontal position of the synchronous belt, thereby increasing its conveying range. Furthermore, during the movement of the sliding block, it moves along the side wall of the limit frame, improving the stability of the lifting platform's movement.

[0022] Furthermore, the drive assembly includes a drive shaft fixed to and coaxially arranged on the synchronous pulley and a gear sleeved on the drive shaft, and the top of the limiting frame is provided with multiple tooth grooves that mesh with the gear.

[0023] By adopting the above technical solution, during the rotation of the synchronous pulley, both the drive shaft connected to the synchronous pulley and the gear connected to the drive shaft rotate. Since the gear meshes with the tooth groove, the purpose of moving the lifting platform is achieved.

[0024] In summary, the present invention has the following beneficial effects: In this application, the existing chain traction structure is removed and replaced with a scissor structure in which the first lifting rod and the second lifting rod are intersected, thereby improving the overall structural stability and strength of the device.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] Example 1: As Figure 1-4 As shown in the embodiment of this application, a table lifting device for a fabric stacking machine is disclosed, including a side plate 1, a displacement component 7, and a connecting component 9. Two side plates 1 are provided. A mounting base 2 is fixed between the two side plates 1, and a lifting table 3 is provided between the two mounting bases 2. Two first lifting rods 4 are rotatably mounted on the mounting base 2, symmetrically arranged about the center of the lifting table 3. A second lifting rod 5 is rotatably mounted on the lifting table 3. The first lifting rods 4 and second lifting rods 5 are arranged intersectingly and rotatably connected. The number of second lifting rods 5 is equal to the number of first lifting rods 4, and their positions correspond one-to-one. The end of the first lifting rod 4 furthest from the mounting base 2 is attached to the lifting table 3. A sliding seat 6 is slidably mounted on the mounting base 2, and the end of the second lifting rod 5 furthest from the lifting table 3 is rotatably mounted on the sliding seat 6. The displacement component 7 drives the sliding seat 6 to move, causing the lower end of the second lifting rod 5 to flip toward or away from the lower end of the first lifting rod 4. At the same time, the upper end of the first lifting rod 4 moves toward or away from the upper end of the second lifting rod 5, thereby causing the lifting platform 3 to rise or fall, thus changing the height of the fabric. This product removes the existing chain 824 traction structure and replaces it with a scissor structure in which the first lifting rod 4 and the second lifting rod 5 are intersected, improving the overall structural stability and strength of the device.

[0029] The displacement assembly 7 is mounted on the side plate 1 and is used to drive the sliding seat 6 to move. The displacement assembly 7 includes a displacement motor 71, a reducer 72, a coupling 73, and a lead screw 74. The displacement motor 71 is fixed to one of the side plates 1. The reducer 72 is connected to the output end of the displacement motor 71 (the reducer 72 mainly includes a worm gear and a worm. The worm is fixed to the output end of the displacement motor 71, and the worm gear is fixed to the coupling 73. The worm and worm gear mesh. The structure of other parts of the reducer 72 is existing technology and will not be described in detail here). The coupling 73 is connected to the output end of the reducer 72. The lead screw 74 is fixed to the coupling 73 and coaxially arranged with the coupling 73. The lead screw 74 passes through the sliding seat 6 and is threadedly connected. After the displacement motor 71 starts working, the reducer 72 reduces the speed of the output end of the displacement motor 71 and transmits the speed to the coupling 73 through the output end of the reducer 72, thereby causing the lead screw 74 to rotate. Since the lead screw 74 is threadedly connected to the sliding seat 6, the sliding seat 6 can move. By reducing the speed of the displacement motor 71, the load on the displacement motor 71 is reduced, thereby reducing the heat generated by the motor due to long-term operation and improving the service life and accuracy of the motor.

[0030] A conveying mechanism 8 is mounted on the lifting platform 3. The conveying mechanism 8 includes a conveying component 81 and a rotating component 82. The conveying component 81 includes a main synchronous pulley 811, a driven synchronous pulley 812, and a synchronous belt 813. The main synchronous pulley 811 is rotatably mounted on the lifting platform 3. The driven synchronous pulley 812 is rotatably mounted on the lifting platform 3. The synchronous belt 813 is fitted onto the lifting platform 3 and engages with both the main synchronous pulley 811 and the driven synchronous pulley 812. The rotating component 82 drives the main synchronous pulley 811 to rotate, thereby causing both the synchronous belt 813 engaging with the main synchronous pulley 811 and the driven synchronous pulley 812 engaging with the synchronous belt 813 to rotate, facilitating the removal or storage of fabric from the lifting platform 3.

[0031] The rotating assembly 82 drives the main synchronous pulley 811 to rotate. The rotating assembly 82 includes a rotating motor 821, a main sprocket 822, a driven sprocket 823, and a chain 824. The rotating motor 821 is fixed to the lifting platform 3. The main sprocket 822 is fixedly sleeved on the output end of the rotating motor 821. The driven sprocket 823 is fixedly sleeved on the main synchronous pulley 811. The chain 824 connects the main sprocket 822 and the driven sprocket 823, and the chain 824 meshes with both the main sprocket 822 and the driven sprocket 823. After the rotating motor 821 operates, the main sprocket 822 connected to the output end of the rotating motor 821, the chain 824 connected to the main sprocket 822, the driven sprocket 823 meshing with the chain 824, and the main synchronous pulley 811 fixed to the driven sprocket 823 all rotate, thereby ensuring the normal removal or storage of the fabric.

[0032] The connecting assembly 9 is mounted on the sliding seat 6 and includes a connecting column 91, a roller 92, and a limiting plate 93. The connecting column 91 is rotatably mounted on the sliding seat 6, passing through the end of the second lifting rod 5 away from the lifting platform 3 and rotatably connected. The roller 92 is mounted on the connecting column 91, and the limiting plate 93 is fixed to the mounting base 2 and slides in cooperation with the roller 92. The number of connecting assemblies 9 is equal to the number of second lifting rods 5, and their positions correspond one-to-one. During the sliding of the lower end of the second lifting rod 5, the roller 92 slides within the limiting plate 93, improving the stability of the movement of the second lifting rod 5.

[0033] Roller 92 is rotatably connected to connecting post 91, and roller 92 and connecting post 91 are coaxially arranged. The rotatable connection between roller 92 and connecting post 91 reduces the friction between roller 92 and limiting plate 93.

[0034] The surface of the timing belt 813 has grooves with a wavy structure. This increases the friction of the fabric on the timing belt 813.

[0035] Example 2: Figure 5-6 As shown, the embodiments of this application are based on Embodiment 1 with the following additions; Specifically, a moving mechanism 10 is jointly provided on the side plate 1 and the lifting platform 3. The moving mechanism 10 includes a limiting component 101 and a driving component 102. The limiting component 101 includes a fixed frame 1011, a sliding block 1012, and a limiting bracket 1013. The fixed frame 1011 is disposed between the two side plates 1, and the upper end of the second lifting rod 5 is rotatably mounted on the bottom of the fixed frame 1011.

The limiting bracket 1013 is fixed on the fixed frame 1011, and the limiting bracket 1013 passes through the sliding block 1012 and is slidably engaged. By driving the lifting platform 3 with the drive component 102, both the synchronous belt 813 and the sliding block 1012 connected to the lifting platform 3 can move, thereby adjusting the horizontal position of the synchronous belt 813 and increasing its conveying range. Furthermore, during the movement of the sliding block 1012, it moves along the side wall of the limit frame 1013, improving the stability of the lifting platform 3's movement.

[0036] The drive assembly 102 is used to drive the lifting platform 3 to move. The drive assembly 102 includes a drive shaft 1021 and a gear 1022. The drive shaft 1021 is fixed to and coaxially arranged with the driven synchronous pulley 812. The gear 1022 is fixedly sleeved on the drive shaft 1021. The top of the limiting frame 1013 has multiple tooth grooves 1023 that mesh with the gear 1022. During the rotation of the driven synchronous pulley 812, both the drive shaft 1021 connected to the driven synchronous pulley 812 and the gear 1022 connected to the drive shaft 1021 rotate. Since the gear 1022 meshes with the tooth grooves 1023, the purpose of moving the lifting platform 3 is achieved.
