Description

TECHNICAL FIELD

[0001] The utility model relates to a tobacco leaf rolling clamp technical field especially relates to a kind of tobacco leaf rolling clamp convenient to clamp. BACKGROUND

[0002] In the tobacco leaf planting and processing field, tobacco leaf rolling is the key process in the initial processing link of tobacco leaf, and its purpose is to orderly clamp and fix the picked tobacco leaf, so as to carry out subsequent airing, baking and other treatments, which directly affects the final quality of tobacco leaf.

[0003] In the current traditional tobacco leaf rolling mode, tobacco farmers need to manually arrange and align the tobacco leaf, and then fix it by means of rope binding and bamboo clamp clamping. In this process, the positioning and clamping of the tobacco leaf are entirely dependent on manual operation, which not only requires repeated adjustment of the position of the tobacco leaf to ensure neatness, but also needs to exert a relatively large force to complete clamping. The single rolling capacity is limited, and long-time operation can easily lead to hand fatigue, which seriously restricts the rolling efficiency and cannot meet the needs of large-scale planting. Although the existing simple tobacco leaf rolling tool can reduce the work intensity, it mainly adopts a single clamping structure and lacks precise positioning and locking design. In the clamping process, if the force is not properly controlled, the tobacco leaf may be clamped too loosely, causing it to shift, or clamped too tightly, causing it to break. At the same time, if the clamped tobacco leaf is subjected to slight external impact, the clamping structure may fail, requiring re-adjustment, which further increases the operation complexity.

Detailed Implementation

[0025] Example: A convenient cigarette clip, such as... Figures 1-11As shown, the assembly includes a worktable 1, a lower clamp 2, a positioning block 201, a first spring 202, a second spring 203, a wedge block 204, a cylinder 3, a mounting frame 301, an upper clamp 303, a buckle 306, a controller 5, an installation assembly, and an unloading assembly. The controller 5 is bolted to the front left side of the worktable 1. A positioning groove is provided on the rear top side of the worktable 1, and the lower clamp 2 is fitted into the positioning groove to form a sliding fit. The front and rear side walls of the upper side of the lower clamp 2 are spaced apart. Three positioning blocks 201 are slidably connected. The top of each positioning block 201 is a triangular pyramidal structure. Four first springs 202 are connected between the bottom of each positioning block 201 and the lower clamp 2. An inclined block 204 is slidably connected to the inner side of each positioning block 201. Two second springs 203 are connected between the inclined block 204 and the inside of the positioning block 201. The top surface of the inclined block 204 is an inclined structure, and its bottom surface is a flat structure. A cylinder 3 is mounted on the upper rear side wall of the worktable 1 via a bracket. The cylinder 3 is connected to the control... The device 5 is electrically connected. The cylinder 3 telescopic rod is connected to the mounting frame 301. The upper weaving clamp 303 is detachably connected to the mounting frame 301 through the mounting assembly. The upper weaving clamp 303 is located at the bottom of the mounting frame 301. The upper weaving clamp 303 and the lower weaving clamp 2 are precisely aligned vertically. The two work together to clamp and hold the tobacco leaves. Three buckles 306 are connected at intervals on both the front and rear sides of the bottom of the upper weaving clamp 303. The buckles 306 are precisely aligned with the positioning blocks 201 one-to-one. Furthermore, the buckle 306 can engage with the inclined block 204. The angle between the top inclined surface of the inclined block 204 and the horizontal plane is 15°-45°. The inclined block 204 is made of wear-resistant alloy material (to improve the wear resistance and service life of the structure). The surface of the inclined block 204 that contacts the buckle 306 is coated with polytetrafluoroethylene (which can significantly reduce the frictional resistance when the two slide relative to each other, making the buckle 306 push the inclined block 204 more smoothly and reducing jamming). The worktable 1 is equipped with a material unloading assembly.

[0026] like Figures 6-7 As shown, the mounting assembly includes a locking block 304 and a third spring 305. Three slots 302 are spaced apart on the front and rear side walls of the lower part of the mounting frame 301. The upper clamp 303 is slidably connected to the locking block 304 at the position corresponding to the slot 302. Two third springs 305 are connected between the locking block 304 and the interior of the upper clamp 303. The upper and lower surfaces of the locking block 304 are machined with bevels, and the locking block 304 is adapted to be locked into the corresponding slot 302, forming a locking and engaging structure.

[0027] like Figure 1 and 8 - Figure 11As shown, the unloading assembly includes a motor 4, a screw 401, a first push plate 402, a second push plate 403, a top plate 404, a trapezoidal block 405, and a fourth spring 406. The motor 4 is symmetrically mounted on the upper rear side of the worktable 1 via bolts. The motor 4 is electrically connected to the controller 5. A screw 401 is connected to the output shaft of the motor 4. A first push plate 402 is threaded onto the screw 401. The first push plate 402 and the worktable 1 are in a sliding connection relationship. The first push plate 402 is aligned with the lower clamp 2, and the two are in contact. A second push plate 403 is connected to the bottom of the first push plate 402. 403 and the two sides of the worktable 1 form a sliding fit. The bottom of the worktable 1 is slidably connected to the position corresponding to the positioning groove. Two fourth springs 406 are connected between the top plate 404 and the bottom of the worktable 1. The middle area of ​​the positioning groove on the worktable 1 is set as a hollow structure. The length of the top plate 404 is adapted to the hollow area to ensure that the top plate 404 can smoothly lift the lower clamp 2. Trapezoidal blocks 405 are symmetrically welded to the bottom of the top plate 404. The front and back of the trapezoidal blocks 405 are machined with bevels. The second push plate 403 and the trapezoidal blocks 405 are precisely aligned and form a contact fit relationship.

[0028] During the tobacco leaf arrangement process, the operator first places the lower clamp 2 in the positioning groove, and then lays the tobacco leaves flat on the upper surface of the lower clamp 2. Next, the upper clamp 303 is pushed upward into the mounting frame 301. During this process, the inclined surface of the locking block 304 contacts the bottom edge of the mounting frame 301 and slides relative to it, forcing the locking block 304 to retract and move inward. The third spring 305 is compressed simultaneously. When the locking block 304 moves to align with the slot 302, the third spring 305 elastically resets, driving the locking block 304 to move outward and lock into the slot 302, realizing a quick and detachable connection between the upper clamp 303 and the mounting frame 301. Then, the controller 5 is operated to start the cylinder 3. The telescopic rod of the cylinder 3 extends and drives the mounting frame 301 and the upper clamp 303 to retract and move inward. 03. Simultaneously move downwards; when the latch 306 on the upper clamp 303 contacts the positioning block 201, the latch 306 engages with the triangular pyramidal structure of the positioning block 201. During this process, the first spring 202 achieves a buffering effect on the positioning block 201 through elastic deformation. Immediately afterwards, the positioning block 201 contacts the inclined surface of the inclined block 204, pushing the inclined block 204 to move outwards and retract into the positioning block 201. The second spring 203 is simultaneously compressed. When the latch 306 completely passes the inclined surface of the inclined block 204, the second spring 203 elastically resets, driving the inclined block 204 to move inwards and form a latching engagement with the latch 306, thereby tightly merging the upper clamp 303 and the lower clamp 2 to achieve rapid clamping and positioning of the tobacco leaves. Subsequently, the telescopic rod of the control cylinder 3 is shortened. The system resets, causing the mounting frame 301 to move upwards. Because the buckle 306 and the inclined block 204 maintain a snap-fit ​​engagement, and the bottom surface of the inclined block 204 is flat, the upward movement of the mounting frame 301 cannot synchronously move the upper braiding clamp 303. This causes the inclined bottom surface of the locking block 304 on the upper braiding clamp 303 to abut against the edge of the slot 302. The locking block 304 is squeezed inwards and disengages from the slot 302. Simultaneously, the third spring 305 is compressed, achieving automatic disengagement of the mounting frame 301 from the upper braiding clamp 303. After disengagement, the third spring 305 elastically resets, causing the locking block 304 to return to its initial position. The operation controller 5 starts the motor 4, and the output shaft of the motor 4 rotates, driving the screw 401 to rotate. The screw 401 drives the first push plate 4 through threaded transmission. 02 moves forward synchronously with the second push plate 403; the first push plate 402 contacts and engages with the lower clamp 2, while the second push plate 403 contacts and slides relative to the rear wall slope of the trapezoidal block 405, thereby pushing the trapezoidal block 405 and the top plate 404 to move upward against the elastic force of the fourth spring 406; the top plate 404 passes through the hollow area of ​​the positioning groove and pushes the lower clamp 2 upward, so that it is freed from the constraint of the positioning groove; at this time, the first push plate 402 can smoothly push the lower clamp 2 and the upper clamp 303 to move forward synchronously, pushing the arranged tobacco leaves out of the worktable 1 for easy unloading; when the second push plate 403 and the trapezoidal block 405 are completely disengaged, the fourth spring 406 elastically resets, driving the top plate 404 and the trapezoidal block 405 to move downward to return to the initial position;After the arranged tobacco leaves are pushed out, the control motor 4 reverses its rotation, causing the screw 401 to reverse, which in turn moves the first push plate 402 and the second push plate 403 backward to reset. The second push plate 403 contacts the inclined front wall of the trapezoidal block 405, causing the trapezoidal block 405 to slide relative to the top plate 404. The second push plate 403 will then smoothly pass over the trapezoidal block 405 and finally reset to its initial position, ready for the next tobacco leaf arrangement operation. Following this operation procedure, continuous tobacco leaf arrangement can be achieved.
