Description

Technical Field

[0001] This application relates to the field of food processing equipment technology, and in particular to a dual electric cylinder lifting drive device. Background Technology

[0002] An electric cylinder lifting drive is a device that achieves linear motion through motor drive, enabling efficient, safe, and precise operation in industrial equipment such as confectionery production.

[0003] In related technologies, traditional electric cylinder lifting drive devices use a motor to drive an electric cylinder to achieve linear motion. During candy production, the raw materials are first mixed. When the mixture reaches a certain consistency, the electric cylinder drives a lifting plate to move linearly. The lifting plate then drives multiple piston rods to inject and suck up the syrup.

[0004] In practical use, it was found that during mass production of candy, with the increased length and width of the lifting plate, uneven force was applied to both sides of the lifting plate when one motor drove one electric cylinder in linear motion, making it impossible to simultaneously and stably perform the injection and suction of syrup. To enable stable control of the lifting plate's movement by the electric cylinders, two sets of electric cylinders were designed for lifting. However, in actual use, when both motors were started simultaneously, the synchronization of the two sets of electric cylinders was difficult to guarantee, so the lifting plate still suffered from unstable lifting. Summary of the Invention

[0005] To improve the stability of the lifting platform, this application provides a dual-cylinder lifting drive device, which has the effect of synchronous and stable lifting action.

[0006] The dual-electric-cylinder lifting drive device provided in this application adopts the following technical solution:

[0007] A dual-cylinder lifting drive device includes a frame, on which a motor and multiple telescopic cylinders are mounted, with the multiple telescopic cylinders located around the motor; the output end of the motor is provided with a drive pulley, and the output end of each telescopic cylinder is provided with a driven pulley; belts are fitted onto the drive pulley and the driven pulley, and the drive pulley and the driven pulley rotate synchronously via the belts; the output end of each telescopic cylinder passes through the frame and is provided with a lifting plate.

[0008] By adopting the above technical solution, a driving pulley is set at the output end of the motor, and a driven pulley is set at the output end of the telescopic cylinder. When the motor is working, since the driving pulley and the driven pulley rotate together through the belt, the output ends of multiple telescopic cylinders rotate at the same speed, which improves the synchronicity of the extension and retraction of the two telescopic cylinders. This allows the lifting plate to rise and fall synchronously under the action of the telescopic cylinder, thus improving the stability of the lifting plate.

[0009] Optionally, the frame is provided with multiple tension pulleys, which are located between the driving pulley and the driven pulley; the belt is a double-toothed belt, and the tension pulley is located on the side of the double-toothed belt away from the driving pulley; the double-toothed belt is meshed with the driving pulley, the driven pulley and the tension pulley.

[0010] By adopting the above technical solution, the tension pulley is located between the driven pulley and the driving pulley. When the driving and driven pulleys rotate synchronously with the tension pulley via the double-sided toothed belt, the tension pulley can adjust the initial tension of the double-sided toothed belt, reducing vibration and maintaining transmission stability. Simultaneously, the tension pulley, located outside the double-sided toothed belt, can effectively compress the belt, mitigating slippage and compensating for wear when parts of the belt are too loose or too tight. The tension pulley's meshing connection with the driving and driven pulleys via the double-sided toothed belt facilitates the synchronous extension and retraction of the telescopic cylinder, further improving the stability of the lifting plate's raising and lowering.

[0011] Optionally, the frame is provided with a waist-shaped hole, and both ends of the tensioning pulley shaft are provided with protrusions. The protrusions are inserted into the waist-shaped hole, and the frame is provided with a retaining member that passes through the waist-shaped hole and abuts against the protrusion.

[0012] By adopting the above technical solution, a protrusion is provided on the tension pulley, and the protrusion is inserted into the oblong hole. During installation, the position of the tension pulley can be adjusted by abutting the protrusion with a clamping member, which facilitates installation and control.

[0013] Optionally, the clamping element is a bolt.

[0014] By adopting the above technical solution, the installation process is relatively simple when screwing in the bolts, and the magnitude of the tightening force can be controlled.

[0015] Optionally, the frame includes a support plate and multiple limiting rods. The limiting rods are fixed to the bottom of the support plate, and multiple limiting holes are opened on the surface of the lifting plate. The limiting rods are inserted into the limiting holes.

[0016] By adopting the above technical solution, when the lifting plate is in lifting motion, the limit rod is inserted into the limit hole, which can reduce the shaking or deviation of the lifting plate and improve the stability of the lifting plate.

[0017] Optionally, the limiting ring and the limiting hole are concentrically arranged, and a rod sleeve is provided inside the limiting ring, with the limiting rod inserted into the rod sleeve.

[0018] By adopting the above technical solution, a sleeve is set inside the limiting ring, and the limiting rod is inserted into the sleeve. The sleeve provides support and stability for the limiting rod. When the limiting rod is subjected to external force, the sleeve can disperse the force and effectively reduce the bending or deformation of the limiting rod.

[0019] Optionally, the support plate is equipped with multiple limiting plates along its length, and the limiting plates are located at the electrical...

[0020] And both sides of the telescopic cylinder.

[0021] By adopting the above technical solution, the limiting plates restrict the swaying of the motor and telescopic cylinder during operation. When the motor vibrates or the telescopic cylinder extends or retracts, the limiting plates on both sides can reduce unnecessary lateral movement and maintain stability during operation.

[0022] Optionally, the telescopic cylinder includes a cylinder body, a rotating rod, and a lead screw. The cylinder body is mounted on a support plate, the rotating rod is rotatably mounted inside the cylinder body, the lead screw is inserted into the rotating rod and threadedly connected to the rotating rod, and the end of the lead screw away from the rotating rod is fixed to the lifting plate.

[0023] By adopting the above technical solution, the rotating rod is threadedly connected to the lead screw, and the rotational motion of the rotating rod is converted into the linear motion of the lead screw, making the telescopic cylinder's telescopic motion smoother and helping to further improve the stability of the lifting plate.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. An active pulley is set at the output end of the motor, and a driven pulley is set at the output end of the telescopic cylinder. The active pulley and the driven pulley are driven synchronously by a double-sided toothed belt, so that the active pulley and the driven pulley rotate at the same speed. This helps to improve the synchronicity of the telescopic cylinder's extension and retraction, and effectively improves the stability of the lifting plate.

[0026] 2. By setting multiple tension pulleys on the frame, when the double-sided toothed belt is slack or slips, the tension pulleys can press against the double-sided toothed belt, and the double-sided toothed belt will generate a force in the opposite direction on the tension pulley, thereby achieving tension and improving the stability of the double-sided toothed belt drive.

[0027] 3. By opening multiple waist-shaped holes on the frame, the installation position of the tension pulley can be adjusted when tightening the double-sided toothed belt, which is beneficial to the stability of the double-sided toothed belt drive. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0034] This application discloses a dual-electric-cylinder lifting drive device, referring to... Figure 1 The system includes a frame 1, which comprises a support plate 101 and four limiting rods 102 fixed to the bottom of the support plate 101. A fixing shell 16 is fixed to the top of the support plate 101, and a motor 2 and two telescopic cylinders 3 are mounted on the fixing shell 16. The motor 2 is located between the two telescopic cylinders 3. (See reference...) Figure 2 The output end of the telescopic cylinder 3 passes through the support plate 101 and is equipped with a lifting plate 7. A filling seat 17 is fixed on the side of the lifting plate 7 away from the telescopic cylinder 3. The two telescopic cylinders 3 are driven to extend and retract by the motor 2, so that the lifting plate 7 moves up and down on the support plate 101 along with the extension and retraction of the telescopic cylinders 3. Then the filling seat 17 performs filling and suction actions on the syrup.

[0035] Reference Figure 2 To improve the stability of the lifting plate 7 as it rises and falls on the support plate 101, four limiting holes 12 are provided on the surface of the lifting plate 7. A limiting ring 13 is fixed on the lifting plate 7, located on the side of the lifting plate 7 closest to the support plate 101, and is concentrically arranged with the limiting holes 12. A rod sleeve 14 is fixed to the inner thread of the limiting ring 13, and a limiting rod 102 is inserted into the rod sleeve 14. When the motor 2 drives the telescopic cylinder 3 to extend or retract, the limiting rod 102 slides in contact with the rod sleeve 14, which helps to improve the stability of the lifting plate 7 as it rises and falls.

[0036] Reference Figure 2 and Figure 3The telescopic cylinder 3 includes a cylinder body 301, a rotating rod 302, and a lead screw 303. The cylinder body 301 is fixed to the fixed housing 16. The rotating rod 302 is rotatably connected inside the cylinder body 301. The lead screw 303 passes through the rotating rod 302 and is threadedly connected to the rotating rod 302. To improve the synchronicity of the extension and retraction of the two telescopic cylinders 3, a driven pulley 5 is fixed to the end of the rotating rod 302 away from the cylinder body 301, and a driving pulley 4 is fixed to the output end of the motor 2. A belt 6 is fitted onto the driving pulley 4 and the driven pulley 5. In this embodiment, the belt 6 is a double-toothed belt. The double-toothed belt meshes with the driving pulley 4 and the driven pulley 5. When the motor 2 is turned on, the motor 2 drives the driving pulley 4 to rotate, and then the double-toothed belt drives the driven pulley 5 to rotate synchronously, so that the two telescopic cylinders 3 extend and retract together, improving the synchronicity of the extension and retraction of the telescopic cylinders 3.

[0037] Reference Figure 2 and Figure 3 To improve the stability of the double-sided toothed belt drive, two tension pulleys 8 are provided on the support plate 101, which are located between the driving pulley 4 and the driven pulley 5. The driving pulley 4 and the driven pulley 5 are respectively engaged with the inner side of the double-sided toothed belt, and the tension pulley 8 is engaged with the outer side of the double-sided toothed belt.

[0038] Reference Figure 2 and Figure 4 To facilitate quick installation of the tension pulley 8, both the top of the fixed housing 16 and the bottom of the support plate 101 have oblong holes 9. Both ends of the tension pulley 8 shaft are fixed with protrusions 10, which are located within the oblong holes 9. The sides of both the fixed housing 16 and the support plate 101 are threaded with clamping members 11. In this embodiment, the clamping member 11 is a bolt. One end of the bolt passes through the oblong hole 9 and abuts against the protrusion 10. When the motor 2 is operating, the bolt abuts against the protrusion 10 of the tension pulley 8, causing the tension pulley 8 to abut against the double-toothed belt. The double-toothed belt generates a force in the opposite direction on the tension pulley 8, thereby achieving tension and improving the stability of the double-toothed belt drive.

[0039] The implementation principle of the dual-cylinder lifting drive device disclosed in this application is as follows: a drive pulley 4 is set on the motor 2, and a driven pulley 5 is set on the telescopic cylinder 3. The drive pulley 4 and the driven pulley 5 are then connected by a double-sided toothed belt. When the motor 2 is working, the drive pulley 4 drives the two driven pulleys 5 to synchronously transmit power through the double-sided toothed belt. The driven pulleys 5 drive the telescopic cylinder 3 to synchronously extend and retract. The lifting plate 7 rises and falls synchronously on the support plate 101 as the telescopic cylinder extends and retracts, thus improving the synchronicity of the extension and retraction of the telescopic cylinder 3. At the same time, a tension pulley 8 is set between the drive pulley 4 and the driven pulleys 5. When the double-sided toothed belt is slack or slips, the tension pulley 8 is adjusted to a suitable position with the double-sided toothed belt by bolts to achieve the tensioning function of the double-sided toothed belt.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
