AI Technical Summary
Existing tobacco clamps cause tobacco leaves to easily scatter during the drying and curing process, and the thinner leaf stalks are difficult to clamp, leading to them falling off.
The clamping structure consists of a top plate, a middle plate, and a bottom plate. It uses the repulsive force of magnets and the action of springs to clamp the tobacco leaves between the middle plate and the bottom plate. The difference in deformation of the soft hairs compensates for the insufficient clamping force of the clamping plate on the thinner leaf petioles, ensuring stable clamping.
This effectively prevents tobacco leaves from scattering during the clamping process, ensures that thinner leaf petioles do not easily fall off, and achieves stable clamping of tobacco leaves and smooth drying and baking.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco processing, specifically a magnetic tobacco clip. Background Technology
[0002] During the drying and curing process of tobacco leaves, tobacco clamps are used to hold the leaf stalks and suspend the tobacco leaves. A common tobacco clamp structure uses two parallel clamping plates or rods, with an elastic element applying pressure to hold the leaf stalks. For example, utility model patent application number 200820052430.8 discloses a tobacco clamp rod, which uses a spreading frame to open two square timbers. After arranging the tobacco leaves between the two timbers, the spreading frame is released, and the two timbers clamp the leaf stalks under the action of spring contraction. This type of structure has the following drawbacks in use:
[0003] First, during the tobacco leaf arrangement process, the tobacco leaves are easily scattered due to the lack of clamping.
[0004] Secondly, because the thickness of tobacco leaf petioles varies and the clamps are made of hard material, thinner petioles may not be able to be clamped tightly and are prone to falling off during drying or baking. Summary of the Invention
[0005] To address the problem that tobacco leaves tend to scatter when arranged in a tobacco clip, and that leaves with thinner stems tend to fall off easily, this invention provides a magnetic tobacco clip.
[0006] The technical solution includes a top plate, a middle plate, and a bottom plate arranged in parallel from top to bottom. A vertical first guide rod is fixed to each of the left and right ends of the bottom plate. A vertical first guide hole is opened at each of the left and right ends of the top plate. The upper end of the first guide rod passes through the first guide hole at the same end, allowing the top plate to slide up and down along the first guide rod. A spring is fitted onto the first guide rod. A radial first pin hole is opened on the first guide rod, and a first pin shaft matching the first pin hole is also included. A second guide rod is fixed to each of the left and right ends of the middle plate. A vertical second guide hole is opened at each of the left and right ends of the top plate. The upper end of the second guide rod passes through the second guide hole at the same end, allowing the middle plate to move up and down relative to the top plate. A magnet is installed on the lower surface of the top plate and the upper surface of the middle plate. The two magnets repel each other, causing the top plate and the middle plate to tend to move away from each other. A radial second pin hole is opened on the second guide rod, and a second pin shaft matching the second pin hole is also included. Soft hairs are densely distributed on the lower surface of the middle plate and the upper surface of the bottom plate.
[0007] The free ends of the soft hairs all tilt backward.
[0008] The upper ends of the first guide rod and the second guide rod are both provided with limiting flanges.
[0009] Both the first pin and the second pin are connected to the upper end of their respective guide rods via a connecting line.
[0010] The magnet is plate-shaped and is installed along the length of the middle plate and the top plate.
[0011] During the clamping process, the present invention can prevent the tobacco leaves from scattering during the clamping process. After clamping, the deformation difference of the soft hairs and the clamping force on the petiole can compensate for the insufficient clamping force of the clamping plate on the thinner petiole, ensuring that all tobacco leaves are stably clamped.

[0021] Referring to the accompanying drawings, this utility model includes a top plate 1, a middle plate 2, and a bottom plate 3 arranged in parallel from top to bottom. A vertical first guide rod 4 is fixed to each of the left and right ends of the bottom plate 3. A vertical first guide hole 5 is opened at each of the left and right ends of the top plate 1. The upper end of the first guide rod 4 passes through the first guide hole 5 at the same end, allowing the top plate 1 to slide up and down along the first guide rod 4. A support spring 6 is fitted onto the first guide rod 4. A radial first pin hole 7 is opened on the first guide rod 4, and a first pin 8 matching the first pin hole 7 is also included. When the top plate 1 is pressed down against the pressure spring until its upper surface is lower than the first pin hole 7, the first pin 8 is inserted into the first pin hole 7, thus restricting the top plate 1 from springing back upwards. A second guide rod 9 is fixed at each of the left and right ends of the middle plate 2. A vertical second guide hole 10 is opened at each of the left and right ends of the top plate 1. The upper end of the second guide rod 9 passes through the second guide hole 10 at the same end, so that the middle plate 2 can move up and down relative to the top plate 1. A magnet 11 is installed on the lower surface of the top plate 1 and the upper surface of the middle plate 2. The two magnets 11 repel each other, so that the top plate 1 and the middle plate 2 tend to move away from each other. A radial second pin hole 12 is opened on the second guide rod 9. It also includes a second pin 13 that matches the second pin hole 12. When the middle plate 2 overcomes the repulsive force of the magnet 11 and approaches the top plate 1 until the second pin hole 12 is higher than the upper surface of the top plate 1, the second pin 13 is inserted, which can restrict the middle plate 2 so that it cannot bounce back downward.
[0022] The lower surface of the middle plate 2 and the upper surface of the bottom plate 3 are densely covered with soft hairs 14. When the middle plate 2 is close to the bottom plate 3, the upper and lower soft hairs 14 interlock with each other. After the petiole of the tobacco leaf is inserted between the middle plate 2 and the bottom plate 3, it will be held by the soft hairs 14 and will not be scattered or easily fall off.
[0023] The free ends of the soft bristles 14 are all tilted to the rear. The petiole of the tobacco leaf is inserted into the soft bristles 14 from front to back in the direction of the bristles, so it is easy to insert. When it is pulled out, it is against the direction of the bristles, so it will not fall out easily.
[0024] The upper ends of the first guide rod 4 and the second guide rod 9 are both provided with limiting flanges 15, which can prevent the top plate 1 from slipping off the first guide rod 4 and the second guide rod 9.
[0025] Both the first pin 8 and the second pin 13 are hung on the upper end of the corresponding guide rod by a connecting line 16 to prevent the pins from being lost.
[0026] The magnet 11 is plate-shaped and is installed along the length of the middle plate 2 and the top plate 1, so that the magnetic force is evenly distributed along the length of the middle plate 2, ensuring uniform clamping force on the tobacco leaves.
[0027] This device has three states during use:
[0028] In state one, neither the first pin 8 nor the second pin 13 is inserted into the corresponding pin hole. At this time, under the action of the compression spring and the repulsive force of the magnet 11, the top plate 1 and the bottom plate 3 maintain the maximum distance, and the middle plate 2 and the top plate 1 maintain the maximum distance. The soft bristles 14 on the middle plate 2 and the soft bristles 14 on the bottom plate 3 partially engage. At this time, the petioles of the tobacco leaves can be inserted from front to back into the soft bristles 14 between the bottom plate 3 and the middle plate 2. The soft bristles 14 hold the petioles so that the arranged tobacco leaves will not be scattered or fall off. After the tobacco leaves are arranged between the bottom plate 3 and the middle plate 2, the top plate 1 is pressed down to the lowest limit position, the first pin 8 is inserted into the first pin hole 7, and the second pin 13 is inserted into the second pin hole 12. The device is then moved to state two.
[0029] In state two, the top plate 1 is pressed down to its limit position, and the top plate 1 and the bottom plate 3 maintain the minimum distance. The top plate 1 and the middle plate 2 also maintain the minimum distance. Under the action of the downward repulsive force of the magnet 11 on the middle plate 2, the middle plate 2 and the bottom plate 3 clamp the petiole of the tobacco leaf. At this time, the soft hairs 14 on the middle plate 2 and the soft hairs 14 on the bottom plate 3 are completely engaged. The deformation difference of the soft hairs 14 and the holding force on the petiole can compensate for the insufficient clamping force of the clamping plate on the thinner petiole. In this state, the tobacco leaf can be dried, baked and other processes. When it is necessary to remove the tobacco leaf, pull out the first pin 8 and move the device to state three.
[0030] In state three, after the first pin 8 is pulled out, under the action of the compression spring, the top plate 1 springs back to the highest position and maintains the maximum distance from the bottom plate 3, while the second pin 13 is not pulled out. The middle plate 2 maintains the minimum distance from the top plate 1, and the middle plate 2 maintains the maximum distance from the bottom plate 3. At this time, the soft bristles 14 on the middle plate 2 and the soft bristles 14 on the bottom plate 3 are completely separated, and the tobacco leaves can be easily poured out.
[0031] When reloading the tobacco leaves, remove the second pin 13 and return the device to state one.
[0032] In the process of clamping tobacco leaves, the soft bristles 14 hold the leaf petioles, which can prevent the tobacco leaves from being scattered. After clamping, under the repulsive force of the magnet 11, the middle plate 2 and the bottom plate 3 hold the tobacco leaves. The deformation difference of the soft bristles 14 and the holding force on the leaf petioles can compensate for the insufficient holding force of the clamping plate on thinner leaf petioles, ensuring that all tobacco leaves are stably clamped.
