Description

Technical Field

[0001] This utility model relates to the field of steel grating production technology, and in particular to an automatic feeding machine for steel grating production. Background Technology

[0002] In the continuous production of steel grating, the automatic and neat unloading and stacking of finished steel grating at the end of the production line is a key step in improving overall production efficiency. Existing automated unloading equipment often employs complex servo motors, sensors, and pneumatic centering and clamping mechanisms to achieve precise positioning and gripping of the steel grating, resulting in complex equipment structures and high manufacturing and maintenance costs. Furthermore, accurately separating individual steel grating pieces from a continuously flowing supply while avoiding interference with subsequent materials during gripping is a common challenge in existing technologies.

[0003] Therefore, this application provides an automatic feeding machine for steel grating production to meet the requirements. Utility Model Content

[0004] The purpose of this application is to provide an automatic feeding machine for steel grating production, which aims to solve the problems of complex structure, high cost, and difficulty in effectively handling continuous material feeding in the existing automatic feeding equipment.

[0005] To achieve the above objectives, this application provides the following technical solution: an automatic unloading machine for steel grating production, comprising a conveying device, an unloading platform, and a movable frame that can move on a track, wherein the movable frame is provided with an unloading device that can slide on its crossbeam; the core of this solution is that an end positioning mechanism is provided at the end of the conveying device to block and position the first steel grating that has reached the gripping position; at the same time, a blocking and separating mechanism is provided before the end positioning mechanism to block and separate the second steel grating that follows immediately after the first steel grating is positioned.

[0006] Preferably, the conveying device comprises multiple unpowered rotating rollers, and the steel grating moves by the pushing force of subsequent steel gratings. This passive conveying method simplifies the drive structure and reduces energy consumption.

[0007] Preferably, the end positioning mechanism includes a limiting rod mounted on the end positioning platform, the position of which can slide along the conveying direction. By adjusting the position of the limiting rod, it can easily adapt to steel gratings of different lengths, thus offering strong versatility.

[0008] Preferably, the blocking and separating mechanism includes a blocking pressure bar mounted on the blocking and separating platform, which can be raised and lowered by a motor. When the first steel grating is in place, the blocking pressure bar descends, reliably blocking the second steel grating, ensuring single-piece operation during the material unloading process and avoiding linkage interference.

[0009] Preferably, the unloading device is provided with a lifting clamping mechanism and a safety support rod below it.

[0010] Preferably, the end of the safety support rod is equipped with a pulley; during unloading, when the clamping mechanism releases the steel grating, the steel grating falls onto the safety support rod and slides on the safety support rod as the unloading device slides, thereby achieving auxiliary alignment. This design cleverly utilizes the movement of the unloading device itself to correct the final position of the steel grating, making its stacking more neat.

[0011] Preferably, the unloading platform is provided with multiple threaded holes, and an unloading positioning rod is detachably installed in each threaded hole via a threaded rod. This modular design allows the unloading positioning rod to be flexibly arranged and replaced as needed, facilitating the stacking operations of products of different specifications.

[0012] Preferably, In summary, the technical effects and advantages of this utility model are as follows: In this invention, the precise positioning and separation of continuously incoming materials is achieved through an end-positioning mechanism and a blocking separation mechanism in a simple mechanical manner, replacing the traditional complex servo centering system, greatly simplifying the equipment structure and reducing manufacturing costs.

[0013] In this invention, the various mechanisms work together to form a complete automated operation process. From separation, positioning, grabbing to transfer and stacking, the entire process requires no manual intervention and is stable and reliable.

[0014] In this invention, the auxiliary sliding alignment function of the safety support rod during the unloading process, and the precise limiting of the unloading positioning rod, ensure that the edges of the final stacked steel grating are neat, which facilitates subsequent packaging and transportation.

[0018] 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. Example

[0019] refer to Figure 1-4 The automatic unloading machine for steel grating production shown includes a moving frame 1, a conveying device 2, and an unloading platform 3. The moving frame 1 consists of two traveling frames 11 and a crossbeam connecting them, and the entire moving frame 1 can move back and forth on a track 4 laid on the ground.

[0020] In one embodiment of this work, the conveying device 2 is used to receive finished steel gratings from the upstream production line. It consists of several interconnected frames, mainly including a blocking and separating platform 23, several conveying platforms 22, and an end positioning platform 21. All platforms are equipped with multiple freely rotatable, unpowered rotating rollers 24. The movement of the steel gratings on the conveying device 2 is achieved by the pushing force of the subsequent steel gratings continuously conveyed from behind.

[0021] In one embodiment of this work, to achieve precise positioning and individual separation of the steel grating, a limiting rod 25 is provided on the end positioning platform 21. The position of the limiting rod 25 can slide and lock on the platform to prevent the first steel grating from being pushed to the end. A blocking pressure rod 26 is provided on the blocking separation platform 23. The pressure rod is driven by a motor and can move up and down.

[0022] In one embodiment of this invention, a material unloading device 12 is slidably connected to the crossbeam of the movable frame 1. Below the material unloading device 12 is a clamping mechanism 14, such as an electromagnetic chuck or pneumatic gripper (not shown in detail in the prior art), and a safety support rod 13. A rotatable pulley is fixed to the end of the safety support rod 13.

[0023] In one embodiment of this invention, the unloading platform 3 is a fixed platform with multiple threaded holes 32 on its upper surface. The lower end of the unloading positioning rod 31 is provided with a threaded rod 33, which can be installed and positioned on the unloading platform 3 by screwing it into the threaded hole 32.

[0024] The working principle of this practical application is as follows: Conveying and Positioning: The steel gratings on the production line are continuously pushed onto the conveyor device 2 of this equipment. The first steel grating moves forward along the rotating roller 24 until its front end touches the limit rod 25 on the end positioning table 21 and stops, completing the final positioning.

[0025] Separation: When the sensor detects that the first steel grating has arrived, the control system drives the blocking pressure bar 26 on the blocking separation platform 23 to descend, pressing on the rear end of the first steel grating or directly blocking the front end of the second steel grating that follows, reliably blocking the subsequent steel grating queue in place.

[0026] Grabbing and Transfer: The moving frame 1 moves above the conveyor 2. The unloading device 12 on it slides to directly above the first steel grating, then the clamping mechanism 14 and the safety support rod 13 descend, and the clamping mechanism 14 activates to grip the steel grating. Afterward, the clamping mechanism 14 and the safety support rod 13 rise together, lifting the steel grating. Finally, the entire moving frame 1 moves along the track 4, transporting the steel grating above the unloading platform 3.

[0027] Unloading and Alignment: After the moving frame 1 is positioned, the unloading device 12 slides to the preset unloading position. The clamping mechanism 14 and the safety support rod 13 descend, aligning the holes of the steel grating with the unloading positioning rod 31 on the unloading platform 3 and lowering it. The clamping mechanism 14 then releases, at which point the weight of the steel grating is entirely supported by the safety support rod 13. Finally, the unloading device 12 slides backward. Due to the presence of the pulley at the end of the safety support rod 13, the steel grating is smoothly pulled along by its own weight and the constraint of the unloading positioning rod 31, thus aligning its edge with the previous steel grating or reference surface. After the unloading device 12 completely retracts, one unloading cycle is completed. The moving frame 1 returns to its initial position, while the blocking pressure rod 26 rises, allowing subsequent steel gratings to advance, and the next cycle begins.

[0029] Components not described in detail in this article are existing technologies.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
