Description

Technical Field

[0001] The utility model relates to the technical field of low-temperature tobacco production, in particular to an automatic feeding mechanism for a slitting machine. Background Art

[0002] Tobacco flakes are processed tobacco waste such as tobacco stems, tobacco dust and low-grade tobacco leaves discarded in the cigarette production process to produce thin-sheet tobacco regeneration raw materials that meet the requirements of cigarette formula. They are usually transported to the slitting machine in the form of rolls. After slitting, they are mixed with natural tobacco leaves in a certain proportion to make cigarettes. At present, the slitting machine adopts the method of manual loading. Since a single roll of thin sheet material is heavy, it is time-consuming and labor-intensive to transport it manually. In addition, if the material is not loaded in time, it will affect the normal operation of the slitting machine. Summary of the invention

[0003] In order to solve the above problems, the utility model provides an automatic feeding mechanism for a slitting machine, which can specifically adopt the following technical solutions:

[0018] The following is a detailed description of an embodiment of the utility model in conjunction with the accompanying drawings. This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method and a specific working process are given, but the protection scope of the utility model is not limited to the following embodiment.

[0019] The automatic feeding mechanism for a slitting machine described in the utility model comprises a frame and a feeding unit arranged thereon. In this embodiment, there are two feeding units, which are neatly arranged from top to bottom along the frame. Each feeding unit comprises a roll storage and conveying mechanism, a roll unwinding mechanism, a translation mechanism and a roll grabbing mechanism.

[0020] Specifically, Figure 1-3As shown, the roll storage and transportation mechanism is arranged on the horizontal plate of the frame 1, and includes three belt conveyors 2 arranged in the same direction. The belt conveyors 2 have different heights, and the angle of the supporting surface changes along the outer circumference of the roll M, and jointly support the roll M arranged along the length direction of the belt conveyor 2 with the central axis. The length of the supporting surface of each belt conveyor 2 is an integer multiple of the width of a single roll M, thereby forming multiple roll placement positions, and multiple rolls M to be picked up can be placed on the roll storage and transportation mechanism at one time. After the belt conveyor 2 is started, the roll M to be picked up can be conveyed in the direction of the unwinding mechanism.

[0021] The unwinding mechanism is arranged on the vertical plate of the frame 1, and includes a material roll insertion shaft 3 driven by a motor. The material roll insertion shaft 3 is usually an air shaft, which is coaxially arranged with the central axis of the material roll M. Usually, the material roll insertion shaft 3 is arranged at a distance from the belt conveyor 2, and the two are connected through a translation mechanism and a material roll grabbing mechanism.

[0022] The translation mechanism includes a pair of ball screws 41 whose ends are connected to the vertical plates of the frame 1, and the other ends of the ball screws 41 extend above the end of the belt conveyor 2. The two ball screws 41 are parallel to each other, and linear guides 42 in the same direction are arranged on their sides. The nut of each ball screw 41 is slidably connected to the adjacent linear guide 42, and the two screw nuts are connected together through a mounting seat 43. The mounting seat 43 is located above the material roll insertion shaft 3 and reciprocates parallel to the material roll insertion shaft 3. A set of material roll grabbing mechanisms are arranged at both ends of the mounting seat 43.

[0023] The above-mentioned roll grabbing mechanism is symmetrically arranged with respect to the roll M to be grabbed, and each group of roll grabbing mechanisms includes an outer clamping arm 51 and an inner clamping arm 52 which are hingedly connected to the mounting seat 43, and the other ends of the outer clamping arm 51 and the inner clamping arm 52 are hingedly connected to the same clamping piece 53. Among them, the inner clamping arm 52 is connected to the driving motor, and the outer clamping arm 51 moves synchronously with the inner clamping arm 52. Usually, the outer clamping arm 51 and the inner clamping arm 52 are both curved arc-shaped arms. The above-mentioned clamping piece 53 is located in the middle of the roll M to be grabbed, and the contact surface with the roll M to be grabbed is an arc-shaped structure adapted to the roll M to be grabbed. The hinge points of the outer clamping arm 51 and the inner clamping arm 52 of the same group with the mounting seat 43, and the hinge points with the clamping piece 53 are arranged in a parallelogram structure. Compared with the common single-axis gripper, the above parallelogram arrangement structure allows the clamping piece 53 to swing more conveniently and at a controllable angle, thereby improving the gripping strength and ensuring that the clamping piece 53 can fully fit the outer surface of the material roll M to be gripped, and the fitting surface is evenly stressed without damaging the material roll M. In addition, the hinge points of the two sets of outer clamping arms 51 and the inner clamping arm 52 and the mounting seat 43 should also be arranged along the same horizontal line.

[0024] To use, follow these steps:

[0025] Step 1: Start the belt conveyor 2, manually operate the electric forklift to place the material roll M at the input end of the belt conveyor 2, and after the material roll M is pushed forward, continue to load the material until the conveyor belt 2 is fully loaded, and then shut down the belt conveyor 2;

[0026] Step 2: Start the ball screw 41 to move the material roll grabbing mechanism to both sides of the material roll M at the output end of the conveyor belt 2, adjust the opening and closing degree of the clamping arms to make the clamping pieces 53 on both sides hold the material roll M tightly, reverse the ball screw 41, and move the material roll M toward the material roll insertion shaft 3 until the material is loaded onto the material roll insertion shaft 3.

[0027] Step 3: Repeat the above steps to complete the loading of other material rolls M.

[0028] The two groups of feeding units can be operated alternately to leave time for the splicing process and ensure the continuous and uninterrupted operation of the slitting machine.

[0029] It should be noted that, in the description of the present invention, terms indicating orientation or positional relationships, such as "front", "rear", "left", "right", "vertical", "horizontal", "inside", "outside", etc., are based on the orientation or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
