DETAILED DESCRIPTION

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0037] See attached Figure 1 -Attached Figure 7 A device for opening and feeding cigarette clips, comprising a body 1, an opening mechanism 2, a clamping mechanism 3, a lifting mechanism 4 and a feeding mechanism 5; a storage port 10 connecting the outside and the interior of the body 1 is provided on one side of the body 1; the opening mechanism 2 is installed in the body 1 and is designed corresponding to the storage port 10, and is used to carry and open a cigarette clip 6 with tobacco leaves; the clamping mechanism 3 is installed in the body 1 and is located below the opening mechanism 2, for clamping or loosening tobacco leaves; the lifting mechanism 4 is installed in the body 1 and is drivingly connected to the clamping mechanism 3, for driving the clamping mechanism 3 to move up and down; the feeding mechanism 5 is installed on the body 1 and is located above the opening mechanism 2, for clamping and feeding tobacco leaves.

[0038] Specifically, when in use, the cigarette clamp 6 with tobacco leaves is inserted into the body 1 from the storage port 10 and placed on the clamp opening mechanism 2, then the clamping mechanism 3 is started to clamp the tobacco leaves on the cigarette clamp 6, and then the clamp opening mechanism 2 is started to open the cigarette clamp 6, and the clamping mechanism 3 is driven upward by the lifting mechanism 4 to drive the tobacco leaves into the feeding mechanism 5; after the feeding mechanism 5 clamps the tobacco leaves, the clamping mechanism 3 is controlled to release the tobacco leaves, and the tobacco leaves can be transported to the next process through the feeding mechanism 5; after the tobacco leaves are transported, each mechanism is controlled to reset, and the empty cigarette clamp 6 is taken out, and the above operation process is repeated.

[0039] In summary, the present invention designs a clamping mechanism 3 to fix tobacco leaves, thereby preventing the opening mechanism 2 from opening the tobacco clamps 6 and causing the tobacco leaves to fall, and designs a lifting mechanism 4 to drive the clamping mechanism 3 to move upward, so that the tobacco leaves can be transferred to the feeding mechanism 5 and fed to the next process; compared with the manual operation method, the present clamping and feeding equipment has a high degree of automation, and can automatically open the tobacco clamps 6 and take out the tobacco leaves for transportation, so as to improve production efficiency; and there is no need for workers to touch the tobacco leaves during the entire process, which can reduce the possibility of tobacco leaf damage and improve the quality of tobacco leaves.

[0040] See attached Figure 1 -Attached Figure 7 The present invention also includes a control box (not shown in the figure), which is installed on the body 1 and is electrically connected to the clamping mechanism 2, the clamping mechanism 3, the lifting mechanism 4 and the feeding mechanism 5; a control button 11 electrically connected to the control box is installed on the outer wall of the body 1, and a safety grating 12 electrically connected to the control box is also installed at the storage port 10.

[0041] Specifically, after a worker inserts a cigarette holder 6 with tobacco leaves into the machine body 1 through the storage port 10 and places it on the opening mechanism 2, he presses the control button 11 to control the opening mechanism 2, the clamping mechanism 3, the lifting mechanism 4 and the feeding mechanism 5 to operate in sequence according to a preset program, thereby realizing the automatic loading and unloading of tobacco leaves.

[0042] The safety grating 12 is designed to detect whether there is an object at the storage opening 10. If the safety grating 12 detects the presence of a cigarette clip 6, a worker's hand, or other object at the storage opening 10, the safety grating 12 will issue a closing command to the control box. At this time, even if the control button 11 is pressed, the various mechanisms cannot be activated. Therefore, the design of the safety grating 12 can improve operational safety.

[0043] It should be noted that the technology of sending instructions to the control box through the safety grating 12 and the control button 11, thereby controlling the operation of electrical components through the control box, is very common in the field of machinery and belongs to the existing technology. Therefore, the specific circuit structure and operating principle are not elaborated in detail in the present invention.

[0044] See attached Figure 1 -Attached Figure 7 The cigarette holder 6 includes a left pressing plate 61 and a right pressing plate 62, and a pressing pin 63 installed on the left pressing plate 61 or the right pressing plate 62; a bayonet 61k is provided at the end of the left pressing plate 61, and a buckle 62k is provided at the end of the right pressing plate 62. The buckle 62k can be inserted into the bayonet 61k to fix the left pressing plate 61 and the right pressing plate 62 to each other and enclose the pressing pin 63; the opening mechanism 2 includes a base plate 21, a carrier frame 22, a first driving assembly 23 and a top fastener 24; the base plate 21 is provided with two pieces and is located on both sides of the storage port 10; the carrier frame 22 is provided with two pieces and They are slidably mounted on two base plates 21 respectively, and both carrier frames 22 are equipped with carrier rods 22z extending along the Y-axis direction, and limit members 25 designed corresponding to the carrier rods 22z. The two carrier rods 22z are used to carry the cigarette clamp 6, and the two limit members 25 are used to limit the left pressure plate 61 and the right pressure plate 62 respectively; the first drive assembly 23 is provided with two groups and is respectively mounted on the two base plates 21, and is respectively driven and connected to the two carrier frames 22; the push-up member 24 is installed on any carrier frame 22 and can push the buckle 62k away from the bayonet 61k.

[0045] Specifically, when in use, first start the two sets of first drive components 23 to drive the two carrying frames 22 to move closer to each other in the X-axis direction, so that the two carrying rods 22z are close together and aligned with the placement opening 10. After the worker inserts the cigarette clip 6 from the placement opening 10 and places it on the two carrying rods 22z, the two limit members 25 are started to respectively limit the left pressure plate 61 and the right pressure plate 62 of the cigarette clip 6 to complete the placement of the cigarette clip 6.

[0046] After the clamping mechanism 3 clamps the tobacco leaves under the cigarette clamp 6, the buckle 62k on the right pressure plate 62 is pushed away from the buckle 61k on the left pressure plate 61 by the push fastener 24, and then the two groups of first driving components 23 are started to drive the two carrying frames 22 away from each other in the X-axis direction, so that the two carrying rods 22z move away from each other and drive the left pressure plate 61 and the right pressure plate 62 to separate from each other to open the cigarette clamp 6; after the cigarette clamp 6 is opened, the clamping mechanism 3 is driven to move upward and close to the feeding mechanism 5 through the lifting mechanism 4.

[0047] After the feeding mechanism 5 clamps the tobacco leaves, it controls the clamping mechanism 3 to release the tobacco leaves to ensure smooth transportation of the tobacco leaves. During the transportation of the tobacco leaves, the worker can first drive the clamping mechanism 3 back to its original position through the lifting mechanism 4, and then drive the two carrying rods 22z closer to each other through the two groups of first driving components, so that the buckle 62k of the right pressure plate 62 and the bayonet 61k of the left pressure plate 61 are buckled with each other to form a cigarette clamp 6. The worker can wait until the tobacco leaves are transported, and then take out the empty cigarette clamp 6 and replace it with a new cigarette clamp 6 with tobacco leaves.

[0048] Therefore, the coordinated use of the above structures can ensure that the cigarette holder 6 is stably placed, and realize the automatic opening and closing of the cigarette holder 6 and the automatic transportation of tobacco leaves, thereby improving work efficiency and convenience.

[0049] It should be noted that the cigarette clamp 6 is an existing product, and the limiting member 25 and the top fastener 24 of the clamp opening mechanism 2 are also existing products. For example, the limiting member 25 and the top fastener 24 can also adopt an electric cylinder, a screw motor 551 or other mechanisms with a moving stroke. Due to the variety of related products, the present invention does not make specific restrictions on this.

[0050] See attached Figure 1 -Attached Figure 7 For ease of understanding, the limiting member 25 in the present invention includes a first cylinder 251 and an insert block 252. The insert block 252 is located above the cigarette clamp 6. The first cylinder 251 is installed on the carrier frame 22 and is drivingly connected to the insert block 252 to drive the insert block 252 to move up and down along the Z-axis direction; the insert blocks 252 of the two limiting members 25 can be respectively inserted into or detached from the left pressure plate 61 and the right pressure plate 62.

[0051] Specifically, under normal circumstances, the insert blocks 252 of the two limiting members 25 are respectively separated from the left pressure plate 61 and the right pressure plate 62, so that the cigarette clip 6 can be smoothly placed on the two carrying rods 22z; when the cigarette clip 6 is placed, the two first cylinders 251 are started to drive the two insert blocks 252 to move downward and insert into the left pressure plate 61 and the right pressure plate 62, thereby limiting the left pressure plate 61 and the right pressure plate 62 on the two carrying rods 22z respectively.

[0052] When the top fastener 24 squeezes the buckle 62k out of the bayonet 61k, the two groups of first driving components 23 drive the two carrying rods 22z away from each other to open the cigarette holder 6; and when the tobacco leaves are removed, the two groups of first driving components 23 drive the two carrying rods 22z toward each other to re-assemble the cigarette holder 6. At this time, the two first cylinders 251 drive the two inserting blocks 252 to move upward and disengage from the left pressure plate 61 and the right pressure plate 62, so that the empty cigarette holder 6 can be removed from the two carrying rods 22z.

[0053] See attached Figure 1 -Attached Figure 7 For ease of understanding, the top fastener 24 in the present invention includes a support plate 241, a second cylinder 242 and a third cylinder 243; a carrier plate 221 is installed on the carrier frame 22, and a slider 222 is slidably installed on the carrier plate 221; the second cylinder 242 is installed on the carrier plate 221 and is driven and connected to the slider 222; the third cylinder 243 is installed on the slider 222 and is driven and connected to the support plate 241, and a support block 241k is provided on the support plate 241.

[0054] Specifically, under normal circumstances, the stop plate 241 is placed above the carrier plate 221 and offset from the material opening 10 to avoid obstructing the placement of the cigarette holder 6. When the cigarette holder 6 with tobacco leaves is fixed to the two carrier rods 22z and the clamping mechanism 3 clamps the tobacco leaves, the second cylinder 242 is first activated to drive the slider 222 to move along the X-axis direction so that the stop block 241k is aligned with the buckle 62k. Then, the third cylinder 243 is activated to drive the stop plate 241 to move along the Y-axis direction so that the stop block 241k squeezes the buckle 62k out of the buckle 61k.

[0055] When the buckle 62k is disengaged from the latch 61k, the two first driving assemblies 23 need to control the two carrying rods 22z to move away from each other, so that the left pressure plate 61 and the right pressure plate 62 are disengaged from each other. When the cigarette holder 6 is completely opened, the third cylinder 243 drives the support plate 241 to move along the Y-axis direction and away from the buckle 62k, and the second cylinder 242 drives the support plate 241 back to its original position to avoid hindering the removal of the empty cigarette holder 6.

[0056] See attached Figure 1 -Attached Figure 7 A stopper 22d is installed on one end of the two carrying rods 22z away from the storage port 10. When the cigarette clip 6 is placed on the two carrying rods 22z, the stopper 22d abuts against the cigarette clip 6 to limit the movement range of the cigarette clip 6, avoiding excessive movement of the cigarette clip 6 and causing dislocation, thereby further improving the convenience of operation.

[0057] See attached Figure 1 -Attached Figure 7 The clamping mechanism 3 includes a bracket 31 and a second driving assembly 32. The bracket 31 is arranged in the machine body 1 and is located below the clamping mechanism 2, and clamping rods 31z extending along the Y-axis direction are provided on both sides of the bracket 31. The two clamping rods 31z are respectively located on both sides of the storage port 10 and are slidably connected to the bracket 31; the second driving assembly 32 is installed on the bracket 31 and is synchronously driven and connected with the two clamping rods 31z to drive the two clamping rods 31z to move closer to or away from each other along the X-axis direction; the lifting mechanism 4 is driven and connected to the bracket 31 to drive the bracket 31 to move up and down along the Z-axis direction.

[0058] Specifically, when the cigarette clamp 6 with tobacco leaves is placed and fixed on the two carrying rods 22z, the second driving component 32 is started to drive the two clamping rods 31z to move closer to each other along the X-axis direction to clamp the tobacco leaves fixed on the cigarette clamp 6; after the tobacco leaves are clamped, the cigarette clamp 6 is opened by the clamping mechanism 2, and the lifting mechanism 4 is started to drive the bracket 31 to move up along the Z-axis direction, so that the tobacco leaves can be brought closer to the feeding mechanism 5; after the feeding mechanism 5 clamps the tobacco leaf stems, the second driving component 32 is started to drive the two clamping rods 31z to move away from each other along the X-axis direction to loosen the tobacco leaves, and the tobacco leaves can be transported to the next process via the feeding mechanism 5, and the lifting mechanism 4 drives the bracket 31 to move down along the Z-axis direction, so that the two clamping rods 31z return to their original position.

[0059] See attached Figure 1 -Attached Figure 7 The bracket 31 is provided with a accommodating cavity 310 connected to the storage port 10 and opening upward, and the two clamping rods 31z are symmetrically arranged on both sides of the opening of the accommodating cavity 310. When the cigarette clamp 6 is placed on the clamping mechanism 2, the tobacco body of the tobacco leaf hangs down in the accommodating cavity 310; therefore, the design of the accommodating cavity 310 can provide a accommodating space for the tobacco body of the tobacco leaf. On the one hand, it is convenient for workers to place the cigarette clamp 6 with tobacco leaves, and on the other hand, it allows the tobacco leaves to be smoothly unfolded, reducing the possibility of tobacco leaf wrinkles and damage.

[0060] See attached Figure 1 -Attached Figure 7 The lifting mechanism 4 includes a support frame 41, a slide 42 and a third drive assembly 43; the support frame 41 is installed in the machine body 1, the slide 42 is slidably installed on the support frame 41 and fixed to the bracket 31, the third drive assembly 43 is installed on the machine body 1 and the support frame 41, and the third drive assembly 43 is driven and connected to the slide 42 to synchronously drive the slide 42 and the bracket 31 to move up and down along the Z-axis direction, thereby making the two clamping rods 31z move away from or close to the feeding mechanism 5; and when the third drive assembly 43 drives the two clamping rods 31z to approach the feeding mechanism 5, the tobacco stems of the tobacco leaves can be transferred into the feeding mechanism 5.

[0061] Among them, the support frame 41, the slide 42 and the third drive assembly 43 can be set in two or two groups, and are respectively set on both sides of the storage port 10 to improve the operation stability; in addition, in addition to the above-mentioned structure, the lifting mechanism 4 can also adopt other structures with a moving stroke, which is not limited in the present invention.

[0062] See attached Figure 1 -Attached Figure 7 The feeding mechanism 5 includes a fastening plate 51, a fixed frame 52, a wheel belt 53, a fourth driving assembly 54 and a driving wheel group 55. The top side of the body 1 is provided with a material trough 13 connecting the outside and the inside of the body 1, and the material trough 13 extends along the Y-axis direction; there are two fastening plates 51, which are installed on the top of the body 1 and located on both sides of the material trough 13; there are two fixing frames 52 and they are slidably installed on the two fastening plates 51 respectively; there are two groups of fourth driving assemblies 54 and they are respectively installed on the two fastening plates 51, and the two groups of fourth driving assemblies 54 are respectively connected to the two fixing frames 52 for driving;

[0063] There are two wheel belts 53 and they are movably mounted on the two fixed frames 52 respectively, and a clamping groove 530 corresponding to the material trough 13 is formed between the two wheel belts 53 to allow the tobacco leaf stems to be arranged in an orderly manner; there are two driving wheel groups 55 and they are respectively mounted on the two fixed frames 52, and the two driving wheel groups 55 are respectively connected to the two wheel belts 53 to drive the two wheel belts 53 to run synchronously.

[0064] Specifically, under normal circumstances, the two wheel belts 53 are far away from each other, and the clamping groove 530 is in the maximum state; when the lifting mechanism 4 drives the clamping mechanism 3 to move up along the Z-axis direction and allows the tobacco stems to enter the clamping groove 530, the two groups of fourth driving components 54 synchronously drive the two fixed frames 52 to move closer to each other along the X-axis direction, so that the clamping groove 530 formed by the two wheel belts 53 clamps and fixes the leaf stems, and then the two groups of driving wheel assemblies 55 are started to synchronously drive the two wheel belts 53 to run synchronously, so that the tobacco leaves can be transported along the direction of the material trough 13.

[0065] See attached Figure 1 -Attached Figure 7 The driving wheel group 55 includes a motor 551, a driving wheel 552 and an auxiliary wheel 553; at least two driving wheels 552 are provided and are rotatably mounted at both ends of the fixed frame 52, and a plurality of auxiliary wheels 553 are provided and are rotatably mounted on the fixed frame 52 and located between the two driving wheels 552. The belt 53 is wound around the two driving wheels 552 and the plurality of auxiliary wheels 553; the motor 551 is installed on the fixed frame 52 and is drivingly connected to any one of the driving wheels 552; when the motor 551 of the driving wheel group 55 drives the driving wheel 552 to rotate, it can drive the belt 53 to run; and since there are two driving wheel groups 55, the two belts 53 can be driven to run synchronously to smoothly transport tobacco leaves.

[0066] Among them, the design of the two driving wheels 552 is mainly used to drive the wheel belt 53, while the design of the multiple auxiliary wheels 553 can support the wheel belt 53, preventing the tobacco stems behind the wheel belt 53 from being squeezed and sunken, thereby improving the conveying capacity of the wheel belt 53.

[0067] It should also be noted that the first drive assembly 23, the second drive assembly 32, the third drive assembly 43 and the fourth drive assembly 54 described above can be directly composed of one or more electric cylinders / screw motors 551, or other mechanisms with a moving stroke can be used.
