Detailed Implementation

[0023] The following are specific embodiments of the utility model, which are described in conjunction with the accompanying drawings to further illustrate the technical solution of the utility model. However, the utility model is not limited to these embodiments.

[0024] like Figs. 1-3 As shown, the long part feeding device includes a support beam 1, on which several horizontally arranged active rollers 11 are rotatably mounted. Each active roller 11 has an arc-shaped limiting groove 12 to form a straight conveying channel. Above the conveying channel, there is a driven roller 2 that can be vertically raised and lowered. The driven roller 2 is movably connected to the lifting bracket 4 mounted on the support beam 1 through a lifting assembly 3.

[0025] That is, the limiting grooves opened in each active roller are used as the conveying channel, so that the rods can be concentrated on the conveying channel to avoid lateral movement of the rods and improve the conveying efficiency. In addition, several driven rollers that can move up and down are set at intervals above the conveying channel by lifting components. The driven rollers are used to push the rods against the limiting grooves from above to keep the rods transported stably.

[0026] In this embodiment, the lifting assembly 3 includes a roller fixing block 31 and a lifting screw 32 rotatably connected to the upper end of the roller fixing block 31. The lifting screw 32 is threadedly connected to the lifting bracket 4, and the driven roller 2 is rotatably disposed at the lower end of the roller fixing block 31.

[0027] The lifting screw is firmly combined with the lifting support by adopting standard threaded connection technology, and the roller fixing block is fixed on the lifting support plate by threads; the driven roller is installed at the lower end of the roller fixing block to realize precise vertical lifting. This design makes the height of the driven roller adjustable, which can be adjusted according to the thickness of different materials and the feeding requirements, ensures stable feeding pressure, and has stronger adaptability.

[0028] In this embodiment, the lifting support 4 includes two columns 41 arranged on the support beam 1 and a lifting support plate 42 vertically arranged between the two columns 41, and the lifting screw 32 is threadedly connected to the lifting support plate 42. The roller fixing block 31 abuts against the column 41 to limit the rotation of the roller fixing block 31 with the lifting screw 32.

[0029] Two sturdy columns are fixed on the support beam, and a lifting support plate is installed between the two columns. The lifting screw is embedded in the support plate by threaded connection, the roller fixing block is in contact with the column, and the whole structure is prevented from swinging due to the rotation of the screw. This structure ensures the stability and positioning accuracy of the lifting system, and does not produce lateral shaking when adjusting the feeding, ensuring the stability and reliability of the feeding process.

[0030] In this embodiment, the side surface of the roller fixing block 31 is provided with a lifting sliding groove 33 conforming to the lifting track of the driven roller 2, and the column 41 is provided with a sliding block 43 protruding towards the roller fixing block 31, which cooperates with the lifting sliding groove 33 to slide.

[0031] An accurate sliding groove is reserved on the roller fixing block, so that the fixing block can move along the predetermined track during lifting; at the same time, a protruding sliding block is machined on the column to form a guide cooperation with the sliding groove. Through the cooperation of the sliding groove and the sliding block, the vertical motion track of the driven roller can be accurately controlled, which prevents uneven feeding caused by position deviation, and further ensures the stability of the overall operation of the feeding device.

[0032] In this embodiment, the roller fixing block 31 is a C-shaped structure with an opening facing the conveying channel, and the two end surfaces of the driven roller 2 are rotatably connected at the C-shaped opening. The top of the roller fixing block 31 is rotatably connected with a connecting key 34, and the connecting key 34 is fixedly connected with the lower end surface of the lifting screw 32.

[0033] The roller fixing block adopts a C-shaped design, which allows the driven roller to rotate freely in the fixing block and maintain a good position; the connecting key at the top is fixed with the lower end of the lifting screw by welding or fasteners, which ensures the transmission synchronization of the whole lifting mechanism. The design of C-shaped structure and connecting key ensures that the driven roller does not easily fall off or move relatively during feeding, and effectively transmits the driving force of the lifting screw, ensuring the feeding accuracy.

[0034] In this embodiment, the roller fixing block 31 and the driven roller 2 are also provided with buffer springs, so that the driven roller 2 can float up and down according to the force.

[0035] The buffer springs with appropriate stiffness and preload force are installed between the driven roller and the fixing block. When the material impact is encountered during the feeding process, the spring can absorb part of the impact force. This buffering design reduces the risk of impact load of the equipment, reduces the mechanical wear and tear and the error caused by impact during the material transportation process, and improves the overall durability and stability of the device.

[0036] In this embodiment, the upper end of the lifting screw 32 is provided with a lifting handle 35.

[0037] The handle is installed on the lifting screw, which is convenient for the operator to manually adjust the height of the driven roller, so that the feeding device can quickly adapt to the feeding needs of different sizes of materials. The design of the handle simplifies the on-site adjustment work, improves the use convenience and flexibility of the equipment, and facilitates the precise feeding adjustment.

[0038] In this embodiment, the driven roller 2 is provided with an arc-shaped pressing groove 21 around the circumference, and the pressing groove 21 is matched with the conveying channel and has an arc diameter larger than that of the limiting groove 12.

[0039] The arc-shaped pressing groove is processed on the outer surface of the driven roller, which is designed to match the limiting groove formed on the driving roller, so as to ensure that the feeding material is subjected to appropriate pressing force during the conveying process. The pressing groove helps to prevent the long material from deviating from the channel due to vibration or inclination during the feeding process, maintains stable conveying, and also plays an auxiliary guiding role.

[0040] In this embodiment, the limiting groove 12 is provided with inclined guide slopes 13 on both sides of the limiting groove 12.

[0041] On the driving roller, in addition to the arc-shaped limiting groove, inclined guide slopes are processed on both sides of the groove, which help the material to automatically adjust the position during the feeding process and converge to the center channel. The design of the guide slope improves the self-adjusting ability of the feeding channel, so that the long material can always maintain the correct movement direction during the feeding process, prevents deviation, and ensures the feeding efficiency.

[0042] In this embodiment, the shaft of the driving roller 11 is provided with a rotating shaft, both ends of the rotating shaft are rotatably arranged on the support beam 1, and one end of the rotating shaft is driven by a motor.

[0043] The driving roller rotates by being installed on a rotating shaft, the rotating shaft is fixed on the support beam, and one end is driven by a motor to realize continuous rotation of the driving roller and push the materials forward along the conveying channel. Through the motor drive and the rotating shaft structure, the driving roller can realize stable and high-speed rotation, thereby ensuring the continuity and high efficiency of the feeding process and meeting the requirements of the automatic production line for efficient feeding.

[0044] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
