Description

Technical Field

[0001] The utility model relates to the technical field of tobacco processing equipment, in particular to a tobacco leaf separation and grabbing clamp. Background Art

[0002] In the cigarette manufacturing industry, primary tobacco leaf curing, a critical step in converting fresh tobacco leaves into the "raw tobacco" needed for cigarette production, is crucial for ensuring the quality and flavor of cigarette products. The primary curing process not only profoundly changes the physical state and chemical composition of the tobacco leaves, but also significantly improves their storage stability and adaptability to subsequent processing. However, post-curing tobacco leaf processing, particularly the separation of bundled tobacco leaves for subsequent processes such as shredding and rolling, has traditionally relied on manual labor. This is not only labor-intensive but also inefficient, significantly impacting the speed of the entire production line and increasing operating costs.

[0003] Therefore, how to provide a tobacco leaf separation and grabbing clamp that can effectively improve the tobacco leaf separation efficiency is a technical problem that technical personnel in this field currently need to solve. Utility Model Content

[0004] The utility model aims to provide a tobacco leaf separation and grabbing clamp, which solves the technical problem that the existing manual operation of tobacco leaf separation requires a lot of manpower.

[0008] A connecting plate, the top end of which is fixedly connected to the mounting base;

[0009] A mounting plate is fixedly mounted on the bottom of the connecting plate, wherein the bottom end of the mounting plate is connected to the acupuncture suction cup;

[0010] The air nozzle is arranged on both sides of the acupuncture suction cup, and the bottom end of the air nozzle is provided with an air outlet.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0029] See also Figure 1-Figure 2 The present application provides a tobacco leaf separation and grasping clamp, including a mounting base 1, the top end of which is detachably connected to a driving member (not shown in the accompanying drawings), the driving member being an industrial robot or a coordinate system truss robot, and the driving member can make the mounting base 1 move along a motion trajectory; a clamping jaw 2, a plurality of clamping jaws 2 are evenly spaced and arranged at the bottom end of the mounting base 1; the clamping jaw 2 includes: a connecting plate 3, the top end of which is fixedly connected to the mounting base 1; a mounting plate 4, fixedly arranged at the bottom of the connecting plate 3, the connecting plate 3 is located in the middle of the upper end of the mounting plate 4, and the bottom end of the mounting plate 4 is connected to the puncture suction cup 5; an air nozzle 6, which is located on both sides of the puncture suction cup 5, and an air outlet is provided at the bottom end of the air nozzle 6, and the puncture suction cup 5 and the air nozzle 6 are independently connected to the air source channel, so that the working states of the puncture suction cup 5 and the air nozzle 6 can be controlled separately.

[0030] That is to say, the mounting base 1 is detachably connected to the industrial robot or the coordinate system truss robot. Through the driving system, the mounting base 1 and the clamping jaws 2 thereon can be precisely moved and positioned according to a preset motion trajectory to ensure accurate grasping and separation of tobacco leaves. Multiple clamping jaws 2 are evenly spaced at the bottom end of the mounting base 1 to ensure that multiple tobacco leaves can be grasped and processed at the same time. Each clamping jaw 2 includes a connecting plate 3, a mounting plate 4 and a needle suction cup 5.

[0031] The top of the connecting plate 3 is fixedly connected to the mounting base 1, which serves to connect and support the mounting plate 4. The mounting plate 4 is fixed to the bottom of the connecting plate 3 to provide an installation platform for the acupuncture suction cup 5 and the air nozzle 6. The acupuncture suction cup 5 is used to grab tobacco leaves, and a plurality of retractable pins are provided inside the acupuncture suction cup, which can then grab the tobacco leaves and effectively adsorb the surface of the tobacco leaves under the negative pressure of the acupuncture suction cup.

[0032] The air nozzles 6 are located on both sides of the needle sucker 5, and an air outlet is provided at the bottom end thereof to assist the needle sucker 5 in ventilation and blowing off excess tobacco leaves when grabbing tobacco leaves.

[0033] Working principle:

[0034] The industrial robot / coordinate system truss robot ensures that the gripper can accurately dock at the target position according to the preset program and path. When the gripper reaches the grasping position, the needle suction cup is pressed against the upper surface of the tobacco leaf, and the needle suction cup starts to work (that is, ventilation). The internal needles gently penetrate the surface of the tobacco leaf under the drive of air pressure. At the same time, negative pressure is generated inside the needle suction cup to tightly adsorb the tobacco leaf on the suction cup. During the process of the tobacco leaf being adsorbed, the air nozzles on both sides of the needle suction cup start to work, blowing out air to help remove excess tobacco leaves associated with the target tobacco leaf. Then the industrial robot / coordinate system truss robot makes its gripper reach the unloading position, the needle suction cup stops working, and the grabbed tobacco leaf falls into the designated area under the action of gravity.

[0035] In summary, the tobacco leaf separation and grabbing clamp provided in this application reduces the use of manpower, which not only improves the grabbing efficiency, but also reduces labor intensity and cost.

[0036] On the basis of the above embodiment, it also includes a cylinder 7 that passes through the mounting plate 4. The cylinder 7 is symmetrically arranged on both sides of the mounting plate 4. A limit member 71 is fixed to the upper end of the cylinder 7. The bottom end of each cylinder 7 is commonly connected to the acupuncture suction cup 5. The upper end of the cylinder 7 on one side is commonly connected to the sensing sheet 8. The middle part of the connecting plate 3 is connected to the monitoring probe 9. A rebound member is sleeved on the cylinder 7 located between the mounting plate 4 and the acupuncture suction cup 5. The monitoring probe 9 and the driving member both establish signal connections with the controller.

[0037] That is to say, the cylinders 7 are symmetrically arranged on the front and back sides of the mounting plate 4, the bottom end of each cylinder 7 is connected to the acupuncture suction cup 5, and the upper end is fixed with a limiter 71 for limiting the separation of the cylinder 7 from the mounting plate 4.

[0038] The upper end of the cylinder 7 on one side is connected to the sensing piece 8, and the middle part of the connecting plate 3 is connected to the monitoring probe 9. When the acupuncture suction cup 5 is pressed against the upper surface of the tobacco leaf and the driving part continues to move downward, the acupuncture suction cup 5 continues to move upward following the cylinder 7, and then the sensing piece 8 rises together. When the monitoring probe 9 detects the sensing piece 8, it sends a signal to the controller to stop the driving part and start the acupuncture suction cup 5. A rebound part is provided on the cylinder 7 between the mounting plate 4 and the acupuncture suction cup 5. The rebound part acts as a buffer when the acupuncture suction cup 5 contacts the tobacco leaf, reducing impact and vibration.

[0039] The working process is as follows: the driving part drives the mounting plate 4, the cylinder 7, and the puncture suction cup 5 to descend to the predetermined position, so that the puncture suction cup 5 is attached to the upper surface of the tobacco leaf, and then the driving part continues to move downward, but because the puncture suction cup 5 has contacted the tobacco leaf, the cylinder 7 and the sensing piece 8 actually rise relative to the mounting plate 4. When the sensing piece 8 rises to the detection range of the monitoring probe 9, the monitoring probe sends a signal to the controller. After receiving the signal, the controller controls the driving part to stop working, and starts the adsorption function of the puncture suction cup 5 to start working.

[0040] Specifically, since the acupuncture suction cup 5 and the air nozzle 6 are independently connected to the air source channel, specifically, the acupuncture suction cup 5 is connected to the air source channel through a first pipe, and the air nozzle 6 is connected to the air source channel through a second pipe, the first pipe and the second pipe are both correspondingly provided with solenoid valves, and then the controller controls the working status of the acupuncture suction cup 5 and the air nozzle 6 separately by controlling the solenoid valves.

[0041] Based on the above embodiment, the rebound member is a spring, and a linear bearing is provided between the mounting plate 4 and the cylinder 7 .

[0042] Specifically, a spring acts as a rebound element, mounted on cylinder 7 between mounting plate 4 and puncture suction cup 5. When puncture suction cup 5 comes into contact with tobacco leaves, the spring absorbs and cushions the impact and vibrations generated by contact. A linear bearing, positioned between mounting plate 4 and cylinder 7, provides precise guidance and support for the cylinder's upward and downward motion. This bearing reduces friction and resistance during movement, ensuring smoother and more stable movement. It also ensures that cylinder 7 maintains its correct orientation and position during movement, preventing deviation or shaking, thereby improving the system's accuracy and stability.

[0043] Based on the above embodiments, see Figure 3 The mounting base 1 includes a mounting seat 11 and a crossbeam 12. The mounting seat 11 is detachably connected to the driving member. The crossbeam 12 is fixed to the bottom of the mounting seat 11. A connecting frame 13 is symmetrically provided at the bottom end of the crossbeam 12. A plurality of clamps 2 are evenly spaced at the bottom of each connecting frame 13.

[0044] Specifically, the mounting base 11 and the driving member are connected in a detachable manner. When the driving member needs to be replaced or repaired, it can be easily removed by simply loosening the connection member. The crossbeam 12 is fixed to the bottom of the mounting base 11 to play a connecting and supporting role.

[0045] The connecting frame 13 is arranged at the bottom end of the beam 12 and is symmetrically arranged, which helps to balance the weight of the system. Each connecting frame 13 carries a certain number of clamps 2. The number and distribution of the clamps 2 need to be reasonably planned according to actual needs and system size. Specifically, each connecting frame 13 in this application connects 5 clamps 2.

[0046] On the basis of the above embodiment, a reinforcing rib 14 is provided between the mounting seat 11 and the crossbeam 12 ; and a reinforcing plate 15 is provided between the crossbeam 12 and the connecting frame 13 .

[0047] Specifically, the reinforcing rib 14 is provided between the mounting seat 11 and the crossbeam 12 to increase the connection strength between the mounting seat 11 and the crossbeam 12 and prevent deformation or breakage due to uneven force.

[0048] The reinforcement plate 15 is positioned between the crossbeam 12 and the connecting frame 13 to increase the rigidity and stability of the connection between the two, ensuring that the jaws 2 maintain a stable position and angle when gripping tobacco leaves. The thickness, size, and shape of the reinforcement plate 15 need to be designed based on the specific characteristics of the crossbeam 12, connecting frame 13, and jaws 2. Typically, the reinforcement plate 15 is made of steel or other high-strength materials to ensure sufficient load-bearing capacity and rigidity.

[0049] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0050] This document uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
