Description

Technical Field

[0001] This utility model relates to the field of plastic product processing, and in particular to a feeding device for production handling. Background Technology

[0002] In plastic product processing, the feeding process plays a crucial role. Precise and efficient feeding ensures a smooth production process and reduces production stoppages caused by untimely material supply. A suitable feeding device can accurately control the amount and speed of material input, ensuring that plastic raw materials enter the processing equipment evenly and improving product quality stability.

[0003] Existing feeding devices have shortcomings in material height adjustment. They typically employ a mechanically fixed structure, using rigid supports to fix the height of the suction cup. This structure relies on manual adjustment of bolts or multi-position limit switches to achieve height adjustment, but it cannot achieve continuous and precise adjustment. Therefore, the suction cup often fails to accurately align with the material surface when adsorbing materials. Because it cannot be adjusted in a timely and flexible manner according to the actual height of the material, the suction cup frequently experiences positioning deviations during adsorption, leading to adsorption failure. This not only affects feeding efficiency but also causes production process stagnation, thereby increasing production costs. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figure 1 - Figure 5This utility model provides an embodiment of a material feeding device for production handling, including a conveyor 1. Support legs 2 are fixedly connected to the lower end of the conveyor 1's frame. An L-shaped feeding platform 3 is provided at the rear end of the conveyor 1. Support feet 4 are fixedly connected to the lower end of the feeding platform 3. A bearing seat 5 is provided at the upper end of the horizontal section of the feeding platform 3. A main shaft 6 is rotatably connected inside the bearing seat 5. A spur gear 7 is fixedly connected to the outer wall of the main shaft 6. An electric push rod 8 is also provided at the upper end of the horizontal section of the feeding platform 3. A rack 9 is provided at the power output end of the electric push rod 8, and the rack 9 meshes with the spur gear 7. A slide rail 10 is fixedly connected to the upper end of the horizontal section of the feeding platform 3. A slider 11 is slidably connected to the slide rail 10. The right end of the slider 11 is connected to the left end of the rack 9. A horizontally extending cantilever beam 12 is fixedly connected to the upper side of the outer wall of the main shaft 6. A connecting seat 13 is provided at the lower end of the cantilever beam 12, and a cylinder 14 is provided at the lower end of the connecting seat 13. A suction cup 15 for adsorbing materials is provided at the power output end of the cylinder 14. A cavity 16 is opened in the vertical part of the loading platform 3. A lifting module for adjusting the height of the material is provided in the cavity 16. An adjusting plate 17 is provided in the lifting module. A storage box 18 for placing materials is provided at the upper end of the adjusting plate 17. The storage box 18 is located below the suction cup 15. A sliding module for guiding the vertical movement of the adjusting plate 17 is provided on the front inner wall of the cavity 16. The conveyor 1, as the core component of material conveying, is responsible for conveying the materials transported by the loading device to the subsequent production stage according to the set direction and speed. The material platform 3 provides the mounting foundation for other components of the feeding device and serves as a support platform during the material feeding process. The main shaft 6 is supported by bearing number one, ensuring smooth and stable rotation, reducing frictional resistance, and improving transmission efficiency. The main shaft 6 drives the cantilever beam 12 and the connected cylinder 14 and suction cup 15 to perform circular motion, enabling the suction cup 15 to adsorb and transport materials at different positions. The spur gear 7 meshes with the rack 9, converting the linear motion of the rack 9 into its own rotational motion, which in turn drives the main shaft 6 to rotate synchronously, achieving power transmission and motion conversion. The electric push rod 8 serves as the power source, providing power for linear motion. Through the meshing of the rack 9 and the spur gear 7, the linear motion is converted into rotational motion. The rotation of shaft 6 is facilitated by slide rail 10, which provides a sliding track for slider 11. Slider 11 slides on slide rail 10, ensuring the straightness and stability of rack 9's movement. Cantilever beam 12, connecting main shaft 6, cylinder 14, and suction cup 15, transmits the rotational motion of main shaft 6 to cylinder 14 and suction cup 15, enabling suction cup 15 to perform circular motion in the horizontal direction. Connecting seat 13 connects cantilever beam 12 and cylinder 14, serving as a transition and support. Cylinder 14, as a power source, provides the power for linear motion, driving suction cup 15 to perform vertical linear motion, thus enabling suction cup 15 to adsorb and release materials. Suction cup 15 utilizes the principle of negative pressure to adsorb materials, achieving vertical lifting and lowering motion under the drive of cylinder 14.The material is picked up from the storage box 18 and transported above the conveyor 1, then released to complete the loading process. The lifting module adjusts the height of the material to ensure that the suction cup 15 can smoothly pick up the material. The height of the storage box 18 is adjusted by the vertical movement of the adjusting plate 17 on the sliding module. The storage box 18 is used to place the material to be loaded, providing a stable storage space for the material, which facilitates the accurate picking up of the material by the suction cup 15. The sliding module guides the adjusting plate 17 to move linearly in the vertical direction, ensuring the straightness of the movement of the adjusting plate 17.

[0021] Please see Figure 3 - Figure 5In this embodiment, the lifting module includes a second bearing seat 19, with a lead screw 20 rotatably connected inside the second bearing seat 19. A rotary motor 21 is installed at the upper end of the vertical part of the loading platform 3, and the output shaft of the rotary motor 21 is connected to the upper end of the lead screw 20. The outer wall of the lead screw 20 is threadedly connected to the adjusting plate 17. The sliding module includes a second slide rail 22, with the second slide rail 22 installed on the front inner wall of the cavity 16. A second slider 23 is slidably connected to the second slide rail 22, and the surface of the second slider 23 is fixedly connected to one end of the adjusting plate 17. The sliding surfaces of the first slide rail 10 and the second slide rail 22 are coated with a lubricating coating. The threaded surface of the lead screw 20 is provided with an anti-rust coating. The side wall of the storage box 18 is provided with a material height detection device. A photoelectric sensor 24 is electrically connected to the control switch of the rotary motor 21. Rubber blocks with anti-slip textures are provided at the lower ends of the support legs 2 and 4. The second bearing seat 19 provides stable rotational support for the lead screw 20, ensuring its smooth rotation. The lead screw 20 is connected to the output shaft of the rotary motor 21, converting the rotational motion of the motor into its own rotation. Its outer wall is threadedly connected to the adjusting plate 17. When the lead screw 20 rotates, the adjusting plate 17 moves vertically along the lead screw 20 under the action of the threads, thereby adjusting the height of the storage box 18. The threaded surface has an anti-rust coating to effectively prevent the lead screw 20 from being exposed to moisture. In environments with corrosive gases, the lead screw 20 may rust, ensuring transmission accuracy and service life. The rotary motor 21 serves as the power source for the lifting module, providing power for rotational movement. The second slide rail 22 provides a sliding track for the second slider 23, guiding it to move linearly in the vertical direction, thus ensuring the straightness and stability of the adjusting plate 17 during vertical movement, preventing the adjusting plate 17 from shifting or wobbling, and improving the accuracy of material height adjustment. The lubricating coating on the sliding surfaces of the first slide rail 10 and the second slide rail 22 reduces friction between the slider and the slide rail, reducing wear. The photoelectric sensor 24 detects the height of the material in the storage box 18 in real time. When the material height changes, the photoelectric sensor... The sensor 24 converts the detection signal into an electrical signal and transmits it to the control switch of the rotary motor 21. When the material height is lower than the set value, the photoelectric sensor 24 outputs a signal to close the control switch, the rotary motor 21 starts, drives the lead screw 20 to rotate, the adjusting plate 17 rises, and the height of the storage box 18 increases. When the material height reaches the set value, the photoelectric sensor 24 outputs a signal to open the control switch, and the rotary motor 21 stops rotating. The rubber blocks at the lower ends of the support legs 2 and support feet 4 increase the friction between the feeding device and the ground, improve the stability of the device, and prevent the device from sliding or tipping over during operation. The lower ends of the rubber blocks are provided with anti-slip textures, which further increase the friction between the device and the ground and improve the anti-slip effect.

[0022] During the operation, the material is first placed in the storage box 18, and then the electric push rod 8 and cylinder 14 are started. The piston rod of cylinder 14 moves to make the suction cup 15 adsorb the material. Then the electric push rod 8 drives the rack 9 to drive the main shaft 6 to rotate through the meshing relationship, so that the cantilever beam 12 moves above the conveyor 1. Then, the cylinder 14 continues to drive the piston rod, so that the suction cup 15 transfers the material to the conveyor 1.

[0023] When the height of the material in the storage box 18 changes, the photoelectric sensor 24 converts the detection signal into an electrical signal and transmits it to the control switch of the rotary motor 21. The rotary motor 21 is started to drive the lead screw 20 to rotate, raising the height of the adjustment plate 17 and the storage box 18. When the material height reaches the set value, the photoelectric sensor 24 outputs a signal to disconnect the control switch and stop the rotary motor 21.

[0024] Through the above steps, the material is efficiently adsorbed and released by precise positioning and negative pressure principle. The lifting and sliding modules work together to ensure that the suction cup 15 is accurately docked with the material, avoiding adsorption failure, improving the stability of feeding, and solving the problem that the existing feeding device cannot adjust in time according to the actual height of the material, making it difficult for the suction cup 15 to accurately dock with the material.
