Description

Technical Field

[0001] This utility model relates to the field of tobacco production technology, specifically a tobacco leaf cutting device. Background Technology

[0002] In the process of tobacco leaf re-drying, it is necessary to separate the tobacco leaves and stems. Traditional tobacco leaf re-drying production is adapted to large-scale, high-volume production. The leaf and stem separation adopts the leaf-splitting and air-separation mode. This method requires pre-processing such as one leaf moistening, leaf storage, and two leaf moistening processes. It has the characteristics of long process path, large floor space of leaf-splitting and air-separation equipment, and high energy consumption. It is difficult to meet the processing needs of high-end raw materials for small batches and customization. Moreover, the processing process generates a lot of fragments, and the controllability of the processed sheet shape is poor, with large pieces, medium pieces, fragments, and sesame-like pieces. At the same time, the green and diseased areas on the tobacco leaves cannot be completely removed and some of them enter the final product. A small amount of green and diseased pieces mixed into the finished tobacco sheets will also have a certain impact on the quality of cigarettes.

[0003] According to a tobacco leaf cutting device disclosed in patent number CN 222074458 U, the tobacco leaves to be cut are pressed down by rotating a fixed plate when positioning the tobacco leaves. The positioning of the tobacco leaves requires manual operation, which is inefficient and labor-intensive. In addition, when the fixed plate positions the tobacco leaves, the rubber protrusions at its ends press the tobacco leaves tightly, resulting in a small contact area and high local positioning pressure, which can easily lead to the breakage of the tobacco leaves. Furthermore, after the existing tobacco leaf cutting device is completed, a certain amount of broken tobacco leaves will remain on the support table, which is troublesome to clean and also affects the cutting of the next tobacco leaf. Therefore, we propose a tobacco leaf cutting device. Utility Model Content

[0004] The purpose of this invention is to provide a tobacco leaf cutting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tobacco leaf cutting device, including a support base, a support frame fixedly mounted on the top of the support base, and a laser and a camera respectively mounted in the middle of the support frame. A tobacco leaf positioning mechanism for flexibly positioning tobacco leaves is provided on the top of the support base outside the support frame. A first conveyor belt and a second conveyor belt are respectively provided on both sides of the support base. Strip grooves are equidistantly opened on the top of the support base, and a broken leaf collection groove is provided inside the support base below the strip grooves.

[0006] Preferably, the tobacco leaf positioning mechanism includes a positioning frame, a support rod, a pressure plate, and a spring. The positioning frame is provided on the top of the support base, and the two ends of the positioning frame are slidably connected to the two side walls of the support base. The top two ends of the positioning frame are symmetrically provided with sliding holes, and the support rods are slidably connected in the sliding holes. The bottom of the two support rods at both ends of the positioning frame are fixedly connected to the pressure plate. The top end of the support rod is provided with an external thread, and the end of the support rod located at the external thread is threaded with a nut. A spring is sleeved on the outside of the support rod between the positioning frame and the pressure plate.

[0007] Preferably, mounting plates are fixedly connected to the corresponding two side walls of the support frame, and an electric telescopic rod is fixedly installed on the top of the mounting plate. The piston rod end of the electric telescopic rod passes through the mounting plate and is fixedly connected to the positioning frame.

[0008] Preferably, a vibration motor is installed at both ends of the bottom of the support base.

[0009] Preferably, the laser includes a laser head and a laser generator, the laser head is fixedly installed at the top center of the inner wall of the support frame, and the laser generator is fixedly installed at the top of the support frame.

[0010] Preferably, the first conveyor belt is a silicone conveyor belt with microporous adsorption.

[0011] Preferably, the top of the support base is located on the same horizontal plane as the top of the first conveyor belt and the second conveyor belt.

[0012] Preferably, a rubber pad is provided at the bottom of the pressure plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In the conveying process, the tobacco leaves are conveyed by the first conveyor belt. The negative pressure adsorption of the first conveyor belt makes the tobacco leaves flat and fit the conveyor belt, preventing deviation or wrinkles. By controlling the positioning frame to move down, the two pressure plates simultaneously press down and position the two ends of the tobacco leaves. The cooperation of the spring and the rubber pad at the bottom of the pressure plate realizes the flexible pressing of the tobacco leaves, avoiding hard squeezing that would cause damage to the tobacco leaves.

[0015] 2. This utility model uses a laser generator to perform non-contact cutting on the moldy parts of tobacco leaves, avoiding stress damage from traditional mechanical blades and greatly reducing the breakage rate of tobacco leaves. During the cutting process, a small number of broken tobacco leaves automatically fall into the collection trough under the action of the vibration motor, which can ensure the cleanliness of the top of the support base. The use of visual recognition and laser path planning to achieve intelligent cutting greatly improves the cutting accuracy and cutting efficiency. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a tobacco leaf cutting device, including a support base 1, a support frame 4 fixedly mounted on the top of the support base 1, and a laser 17 and a camera 7 respectively mounted on the middle part of the support frame 4.

[0022] The top of the support base 1 is provided with a tobacco leaf positioning mechanism 5 for flexible positioning of tobacco leaves outside the support frame 4. The first conveyor belt 2 and the second conveyor belt 3 are respectively provided on both sides of the support base 1. The top of the support base 1 is provided with strip grooves at equal intervals. The broken leaf collection groove 13 is provided inside the support base 1 below the strip grooves.

[0023] It should be noted that the first conveyor belt 2 can transport the tobacco leaves to be cut to the support seat 1. The length of the tobacco leaves is greater than the length of the support seat 1. After the tobacco leaves are placed on the support seat 1, the camera 7 identifies the moldy parts of the tobacco leaves and then positions the tobacco leaves. After positioning, the laser 17 performs non-contact cutting on the moldy parts of the tobacco leaves to ensure the quality of the tobacco leaves.

[0024] Please see Figure 2 and Figure 3The tobacco leaf positioning mechanism 5 includes a positioning frame 16, a support rod 9, a pressure plate 10, and a spring 11. The positioning frame 16 is provided on the top of the support base 1, and the two ends of the positioning frame 16 are slidably connected to the two side walls of the support base 1. The top two ends of the positioning frame 16 are symmetrically provided with sliding holes, and the support rod 9 is slidably connected in the sliding holes. The bottom of the two support rods 9 at both ends of the positioning frame 16 is fixedly connected to the pressure plate 10. The top end of the support rod 9 is provided with an external thread, and the end of the support rod 9 located at the external thread is threaded with a nut. The spring 11 is sleeved on the outside of the support rod 9 between the positioning frame 16 and the pressure plate 10.

[0025] It should be noted that, in the use of this invention, the tobacco leaves to be cut are fed into the cutting area by the first conveyor belt 2 with a silicone conveyor belt containing microporous adsorption. The negative pressure adsorption makes the tobacco leaves flat and adhere to the conveyor belt, preventing displacement or wrinkles. After the tobacco leaves are conveyed to the support seat 1, the camera 7 captures images of the tobacco leaves in real time to identify the veins, edges and defect areas of the tobacco leaves. The control system of the device controls the electric telescopic rod 15 to work, causing the positioning frame 16 to slide down. The pressure plate 10 inside the positioning frame 16 presses down on the surface of the tobacco leaves. The spring 11 can play a buffering role, and the rubber pad provides cushioning to avoid damage to the tobacco leaves caused by hard compression, generating the optimal cutting path. The control system of the device controls the laser generator 8 to emit laser light, adjusts the laser angle, and the laser head 6 emits a high-energy laser beam to perform non-contact cutting along the predetermined path. After the cutting is completed, the vibration motor 12 works, causing the cut leaves to fall through the strip groove of the support seat 1 into the leaf collection groove 13 below. The cut complete tobacco leaves are sent out by the second conveyor belt 3 to enter the next process.

[0026] Please see Figure 2 Mounting plates 14 are fixedly connected to the corresponding two side walls of the support frame 4, and an electric telescopic rod 15 is fixedly installed on the top of the mounting plate 14. The piston rod end of the electric telescopic rod 15 passes through the mounting plate 14 and is fixedly connected to the positioning frame 16.

[0027] It should be noted that the electric telescopic rod 15 can drive the positioning frame 16 to rise and fall. The two ends of the positioning frame 16 located on the upper part of the support base 1 are both inverted U-shaped structures, and a pressure plate 10 is slidably installed inside the U-shaped structure. When the positioning frame 16 moves down, the pressure plate 10 inside the positioning frame 16 presses down on the surface of the tobacco leaf, pressing down and positioning the two ends outside the moldy area of ​​the tobacco leaf, thereby achieving the positioning of the tobacco leaf.

[0028] Please see Figure 2 Vibration motors 12 are installed at both ends of the bottom of the support base 1.

[0029] It should be noted that the vibration motor 12 is configured to drive the support base 1 to vibrate, so that the broken tobacco leaves on the support base 1 fall into the broken leaf collection trough 13 through the strip groove.

[0030] Please see Figure 2and Figure 3 The laser 17 includes a laser head 6 and a laser generator 8. The laser head 6 is fixedly installed at the top center of the inner wall of the support frame 4, and the laser generator 8 is fixedly installed at the top of the support frame 4.

[0031] It should be noted that the control system of the device controls the laser generator 8 to emit laser light, adjusts the laser angle, and the laser head 6 emits a high-energy laser beam to achieve the cutting of tobacco leaves.

[0032] Please see Figure 1 The first conveyor belt 2 is a silicone conveyor belt with microporous adsorption.

[0033] It should be noted that negative pressure adsorption is used to make the tobacco leaves fit flat against the conveyor belt, preventing them from shifting or wrinkling.

[0034] Please see Figure 1 The top of the support seat 1 is on the same horizontal plane as the top of the first conveyor belt 2 and the second conveyor belt 3.

[0035] It should be noted that setting the top of the support base 1 to be on the same horizontal plane as the top of the first conveyor belt 2 and the second conveyor belt 3 allows the tobacco leaves on the first conveyor belt 2 to be smoothly transported to the support base 1, and the tobacco leaves on the support base 1 can also be easily transported to the second conveyor belt 3.

[0036] A rubber pad is provided at the bottom of the pressure plate 10.

[0037] It should be noted that the rubber pad at the bottom of the pressure plate 10 enables flexible downward pressure on the tobacco leaves.
