Description

Technical Field

[0001] This utility model belongs to the field of tobacco material handling technology, and in particular relates to a tobacco material handling and feeding device. Background Technology

[0002] After the tobacco crop matures, its leaves are used as raw material. Tobacco leaves are generally long and narrow. Tobacco production includes pre-processing stages such as harvesting, sorting, and drying. Before the drying stage, namely the sorting stage, the strip-shaped tobacco leaves need to be laid out parallel to ensure even heating and ventilation during drying, and to avoid localized mold growth or uneven drying. Traditionally, the sorting process involves manual selection and placement, which is inefficient and can easily damage or contaminate the tobacco leaves, thus affecting product quality. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a tobacco feeding and sorting device that can automatically sort and sort strip tobacco leaves, thereby improving production efficiency.

[0004] To achieve the above objectives, this utility model employs the following technical solution: a tobacco feeding and sorting device, comprising a frame; a feed inlet located on one side of the frame; a discharge outlet located on the other side of the frame; a hopper located inside the feed inlet; a conveyor belt located between the feed inlet and the discharge outlet; a picking mechanism located above the conveyor belt, the picking mechanism being used to pick up tobacco leaves from the hopper and place them onto the conveyor belt; and a linear drive mechanism located above the conveyor belt, the linear drive mechanism being fixedly connected to the frame, the linear drive mechanism being used to drive the picking mechanism to perform reciprocating linear motion.

[0005] Optionally, the material handling mechanism includes a fixed base, with limit sleeves on both sides of the fixed base. The limit sleeves are slidably connected to limit rods, with a crossbar connected to the top of the limit rods and a gripping component connected to the bottom of the limit rods.

[0006] Optionally, the fixed base is connected to a motor, the output shaft of the motor is fixedly connected to a first connecting rod, one end of the first connecting rod is hinged to a second connecting rod, and the second connecting rod is slidably connected to the side of the crossbar.

[0007] Optionally, the gripping assembly includes a fixing plate, one side of which is connected to a plurality of needle grippers for gripping tobacco leaves.

[0008] Optionally, the linear drive mechanism is fixedly connected to the frame, and the linear drive mechanism includes a slide rail and a slider slidably connected to the slide rail, with the top of the slider fixedly connected to the bottom of the fixed base.

[0009] Optionally, the hopper includes multiple vertically arranged dividing rods and a base plate slidably connected to the dividing rods. The top of the base plate is used to place tobacco leaves, and a lifting mechanism for adjusting the height of the base plate is provided in the feed inlet.

[0010] Optionally, the lifting mechanism includes at least two forks, one side of which is provided with a drive assembly for driving the forks to move up and down, and the forks are provided with magnetic blocks and positioning pins, and the base plate is provided with a corresponding insertion hole that cooperates with the positioning pin.

[0011] Optionally, the base plate is made of magnetic material.

[0012] Optionally, a baffle is provided inside the discharge port. The baffle is located on one side of the conveyor belt and is used to block the tobacco leaves, allowing the tobacco leaves to fall freely and vertically.

[0013] Optionally, the baffle is V-shaped.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: By setting a linear drive mechanism and a material handling mechanism above the feed inlet, the hopper is pushed into the feed inlet, and the material handling mechanism grabs the tobacco leaves in the hopper and places them on the conveyor belt. The conveyor belt drives the tobacco leaves to move towards the discharge outlet. When the tobacco leaves move to the end of the conveyor belt, they collide with the baffle due to inertia. The baffle corrects the orientation of the tobacco leaves, thereby realizing automated material handling and greatly improving production efficiency. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Example 1 Reference Figures 1-7This embodiment provides a tobacco feeding and handling device, specifically including a frame 1; a feed inlet 2 located on one side of the frame 1; a discharge outlet 3 located on the other side of the frame 1; a hopper 4 located inside the feed inlet 2; a conveyor belt 5 located between the feed inlet 2 and the discharge outlet 3; a picking mechanism 7 located above the conveyor belt 5, which is used to pick up tobacco leaves from the hopper 4 onto the conveyor belt 5; and a linear drive mechanism 6 located above the conveyor belt 5, which is fixedly connected to the frame 1 and is used to drive the picking mechanism 7 to perform reciprocating linear motion.

[0021] The hopper 4 is movable and has wheels installed at the bottom, which makes it easy to replace the hopper 4 in a timely manner and improve efficiency. The top of the hopper 4 is open and a small hopper door is set on one side of the hopper 4. The top of the small hopper door is hinged to the side wall of the hopper 4. The internal condition of the hopper 4 can be observed by pushing, pulling or flipping the small hopper door.

[0022] The frame 1 is also equipped with several door panels that can be opened and closed to close the entire frame 1. The discharge port 3 is connected to the side of the frame 1. The tail of the conveyor belt 5 extends to the outside of the frame 1 and is located inside the discharge port 3. The bottom of the discharge port 3 is open for discharging materials.

[0023] The linear drive mechanism 6 is fixedly connected to the upper crossbeam inside the frame 1. There are two linear drive mechanisms 6 and two material picking mechanisms 7. The two linear drive mechanisms 6 drive the two material picking mechanisms 7 to move alternately, thereby successively carrying out the material picking and unloading process. The working efficiency is high, and the material picking speed can reach 100-180 pieces per minute.

[0024] Example 2 This embodiment provides a tobacco feeding and handling device, which differs from the first embodiment in that the material handling mechanism 7 includes a fixed base 701, and limit sleeves 702 are provided on both sides of the fixed base 701. Limit sleeves 702 are slidably connected to limit rods 703. A crossbar 704 is connected to the top of the limit rod 703, and a gripping component 705 is connected to the bottom of the limit rod 703.

[0025] The fixed base 701 is connected to the motor 706. The output shaft of the motor 706 is fixedly connected to the first connecting rod 707. One end of the first connecting rod 707 is hinged to the second connecting rod 708. The second connecting rod 708 is slidably connected to the side of the crossbar 704.

[0026] The gripping assembly 705 includes a fixing plate 7051, and a plurality of needle grippers 7052 for gripping tobacco leaves are connected to one side of the fixing plate 7051.

[0027] A sliding sleeve is fixedly connected to one side of the fixed plate 7051. The sliding sleeve is slidably connected to the limiting rod 703. A tension spring is provided at the bottom of the limiting rod 703 and is connected to the fixed plate 7051. When the tension spring is in its initial state, and the limiting rod 703 moves downward under external force, the tension spring is stretched, and the limiting rod 703 slides downward along the sliding sleeve. During this process, the height of the fixed plate 7051 remains unchanged. When the tension spring is in a taut state, the limiting rod 703 drives the fixed plate 7051 to move downward synchronously. The tension spring acts as a buffer for the linear movement of the gripping component 705, greatly reducing contact damage to the tobacco leaves when the gripping component 705 presses down. The needle gripper 7052 has two rows of needles at the bottom, which are staggered at a certain angle. The needles penetrate the tobacco leaves to achieve gripping. Tests have shown that the success rate of this gripping method is over 80%, and the needle diameter is small, so the damage to the tobacco leaves is almost negligible. An elastic buffer, such as a nitrogen spring, is provided at the connection between the needle gripper 7052 and the fixing plate 7051 to achieve secondary buffering and further reduce damage to the tobacco leaves.

[0028] The linear drive mechanism 6 is fixedly connected to the frame 1. The linear drive mechanism 6 includes a slide rail 601 and a slider 602 that is slidably connected to the slide rail 601. The top of the slider 602 is fixedly connected to the bottom of the fixed seat 701.

[0029] The hopper 4 includes multiple vertically arranged dividing rods 401 and a base plate 402 slidably connected to the dividing rods 401. The top of the base plate 402 is used to place tobacco leaves. A lifting mechanism for adjusting the height of the base plate 402 is provided inside the feed inlet 2. The lifting mechanism includes at least two forks 801. A drive assembly for driving the forks 801 to move up and down is provided on one side of the forks 801. A magnetic block 802 and a positioning pin 803 are provided on the forks 801. The base plate 402 has corresponding holes that cooperate with the positioning pins 803. The base plate 402 is made of magnetic material.

[0030] A baffle 301 is installed inside the discharge port 3. The baffle 301 is located on one side of the conveyor belt 5. The baffle 301 is used to block the tobacco leaves and allow the tobacco leaves to fall freely and vertically. The baffle 301 is V-shaped.

[0031] The baffle 301 is set in a V shape. When the tobacco leaf leaves leave the conveyor belt 5, they collide with the baffle 301 under their own inertia. The tip of the V-shape blocks the middle of the tobacco leaf leaves, causing the two ends of the tobacco leaf leaves to bend. Then, the tobacco leaf leaves rebound and fall due to their own flexibility, which can improve the uniformity of the tobacco leaf leaves.

[0032] The dividing rods 401 are evenly distributed in a matrix, which can achieve a preliminary dividing effect when feeding material into the empty bin, improving the success rate of subsequent gripping. The drive component is a common power mechanism, located on one side of the fork 801, and its specific structure will not be described in detail here. An infrared sensor is installed at the feed inlet 2 to sense the height of the tobacco leaves in the bin 4. The power mechanism drives the fork 801 to rise or fall, thereby adjusting the base plate 402 to a suitable height for the gripping component 705 to grip the material.

[0033] In use, the hopper 4 filled with tobacco leaves is pushed into the feed inlet 2. The position of the hopper 4 is adjusted so that the insertion hole on the base plate 402 corresponds to the position of the positioning pin 803 on the fork 801. The drive assembly is activated to lift the fork 801, allowing the positioning pin 803 to insert into the insertion hole. Due to the action of the magnetic block 802, the base plate 402 is stably attracted. Then, the two linear drive mechanisms 6 and the two material picking mechanisms 7 are activated to achieve automated material handling. When the hopper 4 needs to be replaced, because there is a support beam under the base plate 402, the fork 801 moves downward, causing the base plate 402 to contact the support beam. The fork 801 continues to move downward, thereby overcoming the resistance of the magnetic block 802 and detaching the hopper 4, allowing a new hopper 4 to be replaced.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
