Description

Technical Field

[0001] This utility model relates to the technical field of tobacco processing equipment, specifically to a tobacco leaf anti-scratching conveying and transporting equipment. Background Technology

[0002] In the production and processing of tobacco leaves, the transportation link from harvesting to curing is crucial, directly affecting the quality of the tobacco leaves and the efficiency of subsequent processing. Tobacco leaves are relatively fragile, especially freshly harvested leaves, which have high water content and are easily damaged. If they are squeezed, scratched, or bumped during transportation, problems such as leaf damage, wrinkling, and browning are very likely to occur. This not only reduces the grade of the tobacco leaves but also affects the final quality indicators such as combustibility and aroma, resulting in economic losses for tobacco farmers and tobacco companies. Currently, tobacco leaf transportation mainly relies on traditional equipment such as bamboo baskets, plastic baskets, or simple trolleys. These devices generally suffer from insufficient protection: the inner walls of bamboo and plastic baskets are relatively hard, and they lack specialized fixing and cushioning structures. During transportation, tobacco leaves are easily damaged due to shaking, stacking, friction, and compression. Although simple trolleys can achieve mobile transportation, most of them lack enclosed or shielding structures, leaving the tobacco leaves exposed and susceptible to contamination from the external environment (such as dust and rain). Furthermore, improper handling during handling and loading / unloading can easily cause the tobacco leaves to scratch. Furthermore, existing transfer equipment has limitations in adaptability and flexibility. Different batches and parts of the tobacco leaf vary in shape and quantity, making it difficult for traditional equipment to adjust the space according to the actual condition of the leaves. This can lead to either excessive space causing the leaves to shake excessively or insufficient space causing excessive compression. Meanwhile, manual handling and loading / unloading of tobacco leaves is not only labor-intensive and inefficient, but also prone to further damage due to improper human operation. Utility Model Content

[0003] The purpose of this utility model is to provide a tobacco leaf anti-scratching transport and transfer device to solve the problems mentioned in the background art. The inner walls of bamboo baskets and plastic baskets are relatively hard and lack a special fixing and cushioning structure. During the transfer process, tobacco leaves are easily damaged due to shaking and stacking. Although simple trolleys can achieve mobile transfer, most of them do not have a closed or shielding structure. The tobacco leaves are exposed to the outside and are easily contaminated by the external environment (such as dust and rain). At the same time, during the handling and loading and unloading process, improper operation can easily cause tobacco leaves to scratch.

[0004] To achieve the above objectives, this utility model provides a tobacco clamp and tobacco leaf anti-scratching conveying and transfer device, including a base. The base has a square structure, with adjusting components installed at the four corners of the top. A baffle is provided between the adjusting components. The baffle is expanded and contracted by adjusting the adjusting components. A square protective space is formed inside the baffle. A tobacco leaf clamp is installed inside the protective space for holding and placing tobacco. The top of the protective space is sealed by a detachable top cover.

[0005] This setup is based on a square base with adjustable components at the four corners of its top. The baffles between the adjustable components can be expanded and contracted through the adjustable components, thereby forming a square protective space inside the baffles. The tobacco clamp is installed inside the protective space to hold the tobacco leaves, and the top is sealed with a removable top cover.

[0006] Preferably, the adjusting component includes a column, the column is hollow and has a lead screw installed inside, a lead screw slider is installed on the lead screw, a lifting rod is connected to the top of the enclosure piece, and the lead screw slider is connected and fixed to both ends of the lifting rod.

[0007] This setting adjusts the internal structure of the column, which is hollow and fitted with a lead screw. The lead screw slider on the lead screw is fixed at both ends to the lifting rod connected to the top of the enclosure panel. When the lead screw rotates, the lead screw slider will drive the lifting rod to move up and down, thereby realizing the expansion and contraction of the enclosure panel.

[0008] Preferably, the upper end of the lead screw is driven to rotate by a lead screw motor.

[0009] In this configuration, the upper end of the lead screw is driven to rotate by a lead screw motor, and the power provided by the motor enables the lead screw to rotate according to the control requirements.

[0010] Preferably, the top cover is made of transparent glass material, and a support block is installed on the upper side of the adjustment component to support the top cover.

[0011] The top cover of this device is made of transparent glass, and the support block on one side of the upper part of the adjustment component supports the top cover, so that the top cover can stably cover the top of the protected space.

[0012] Preferably, the upper outer side of the adjusting component is fixed with a handle for manual pushing and transfer, and the bottom of the base is equipped with casters.

[0013] This feature includes an adjustment mechanism with an outer handle on the upper part providing a point of force for manual pushing, and casters at the bottom of the base enabling flexible steering and movement of the equipment.

[0014] Preferably, the end of the enclosure panel away from the lifting rod is wound up by a winding wheel, and both ends of the winding wheel are fixed to the outer wall of the adjusting component by positioning shafts.

[0015] In this configuration, the end of the enclosure panel furthest from the lifting rod is wound around a take-up reel. The take-up reel is fixed to the outer wall of the adjusting component via a positioning shaft. When the lifting rod raises and unfolds the enclosure panel, the take-up reel rotates to release the enclosure panel. When the lifting rod descends, the take-up reel winds up the enclosure panel.

[0016] Preferably, a torsion spring is installed on the positioning shaft, and the torsion spring is used to drive the enclosure panel to rewind and reset.

[0017] The torsion spring on the positioning shaft of this device deforms and stores elastic potential energy when the enclosure panel is unfolded. When the enclosure panel needs to be retracted, the torsion spring releases the elastic potential energy to drive the winding wheel to rotate, thereby realizing the automatic winding and resetting of the enclosure panel.

[0018] Preferably, the enclosure panel is made of flexible rubber material and has a sponge layer on its surface.

[0019] The fencing panels are made of flexible rubber material with a sponge layer on the surface. The flexible material has good elasticity and deformation capacity, while the sponge layer provides cushioning.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: In this tobacco leaf anti-scratching transport and transfer equipment, the equipment achieves all-round protection for the tobacco leaves through multiple structures. The baffle is made of flexible rubber material with a sponge layer on the surface, which is soft and has good cushioning performance. It can avoid direct rigid contact between the tobacco leaves and the baffle structure, fundamentally reducing leaf damage caused by scratches. At the same time, the design of the protective space keeps the tobacco leaves in a relatively independent environment, reducing the impact of external collisions and compression on the tobacco leaves. Combined with the stable clamping of the tobacco leaves by the tobacco leaf clamping rod, it further reduces the shaking and mutual friction of the tobacco leaves during the transfer process, significantly improving the integrity of the tobacco leaves. In terms of spatial adaptability adjustment, the equipment achieves flexible expansion and contraction of the enclosure panels through adjustable components. Driven by a screw motor, the lead screw rotates, causing the lead screw slider and connected lifting rod to rise and fall, thereby controlling the expansion height of the enclosure panels. Combined with the winding wheel and torsion spring, the size of the protective space can be flexibly adjusted according to the quantity and height of the tobacco leaves. This avoids excessive shaking of the tobacco leaves due to excessive space, while preventing excessive compression due to insufficient space. It meets the transfer needs of different batches and parts of tobacco leaves, improving the versatility of the equipment. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides a tobacco clamp and tobacco leaf anti-scratching conveying and transfer device, such as... Figure 1 , Figure 2 As shown, it includes a base 1, which is a square structure. Adjustment components 2 are installed at the four corners of the top. A baffle plate 3 is set between the adjustment components 2. The baffle plate 3 can be expanded and contracted by adjusting the adjustment components 2. A square protective space is formed inside the baffle plate 3. A tobacco clamp 4 is installed inside the protective space. The tobacco clamp 4 is used to hold and place tobacco. The top of the protective space is sealed by a detachable top cover 5.

[0024] Based on a square base 1, adjustable components 2 are installed at the four corners of its top. The baffles 3 between the adjustable components 2 can be expanded and contracted through the adjustable components 2, thereby forming a square protective space inside the baffles 3. The tobacco clamps 4 are installed inside the protective space to hold the tobacco leaves, and the top is sealed with a removable top cover 5. The effect is that the protective space formed by the adjustable baffles 3 can be flexibly adjusted according to the actual situation. Combined with the clamping of the tobacco leaves by the tobacco clamps 4 and the sealing of the top cover 5, it provides a basic protective environment for the tobacco leaves, reducing the impact of external factors on the tobacco leaves. At the same time, the removable top cover 5 facilitates the loading and unloading of tobacco leaves.

[0025] In this embodiment, as Figure 3As shown, the adjusting component 2 includes a column 21, the column 21 is hollow inside and a lead screw 22 is installed thereon, a lead screw slider 23 is installed on the lead screw 22, and a lifting rod 31 is connected to the top of the enclosure plate 3. The lead screw slider 23 is connected and fixed to both ends of the lifting rod 31.

[0026] The column 21 in the adjusting component 2 is hollow and fitted with a lead screw 22. The lead screw slider 23 on the lead screw 22 is fixed at both ends to the lifting rod 31 connected to the top of the enclosure 3. When the lead screw 22 rotates, the lead screw slider 23 drives the lifting rod 31 to move up and down, thereby expanding and contracting the enclosure 3. The effect is that, through the cooperation of the lead screw 22 and the lead screw slider 23, the rotational motion is converted into the linear motion of the lifting rod 31, precisely controlling the expansion and contraction of the enclosure 3. This makes the adjustment of the protective space size more stable and accurate, improving the equipment's adaptability to different quantities and shapes of tobacco leaves.

[0027] Specifically, such as Figure 3 As shown, the upper end of the lead screw 22 is driven to rotate by the lead screw motor 24.

[0028] The upper end of the lead screw 22 is driven to rotate by the lead screw motor 24. The power provided by the motor enables the lead screw 22 to rotate according to the control requirements. The effect is that the use of the lead screw motor 24 to drive the adjustment of the enclosure panel 3 is automated, eliminating the need for manual operation, saving manpower, and improving adjustment efficiency. At the same time, the motor drive ensures the stability and consistency of the rotation of the lead screw 22, making the expansion and contraction of the enclosure panel 3 more reliable.

[0029] Furthermore, such as Figure 2 As shown, the top cover 5 is made of transparent glass material, and a support block 25 is installed on the upper side of the adjustment component 2, which supports the top cover 5.

[0030] The top cover 5 is made of transparent glass. The support block 25 on one side of the upper part of the adjusting component 2 supports the top cover 5, allowing it to stably cover the top of the protective space. The effect is that the transparent glass top cover 5 can seal the protective space, preventing dust and impurities from entering, while allowing staff to observe the condition of the tobacco leaves inside at any time and detect problems promptly. The support block 25 ensures the stability of the top cover 5, preventing it from slipping during transport and enhancing the safety of the equipment.

[0031] Furthermore, such as Figure 2 As shown, the upper outer side of the adjusting component 2 is fixed with a handle 6 for manual pushing and transfer, and the bottom of the base 1 is equipped with casters 11.

[0032] The handle 6 on the upper outer side of the adjusting component 2 provides a force point for manual pushing, and the casters 11 at the bottom of the base 1 enable flexible turning and movement of the equipment. The effect is that the handle 6 makes it easier for workers to push the equipment, reducing the labor intensity of manual transportation; the casters 11 enable the equipment to move flexibly in different terrains and scenarios, improving the convenience and flexibility of equipment transportation, and facilitating the transfer of tobacco leaves between fields, curing barns and other places.

[0033] Furthermore, such as Figure 4 As shown, the end of the enclosure panel 3 away from the lifting rod 31 is wound up by the winding wheel 32, and both ends of the winding wheel 32 are fixed to the outer wall of the adjusting component 2 by the positioning shaft 321.

[0034] The end of the enclosure panel 3 furthest from the lifting rod 31 is wound around the take-up reel 32. The take-up reel 32 is fixed to the outer wall of the adjusting component 2 via a positioning shaft 321. When the lifting rod 31 drives the enclosure panel 3 to rise and unfold, the take-up reel 32 rotates to release the enclosure panel 3. When the lifting rod 31 descends, the take-up reel 32 winds up the enclosure panel 3. The effect is that the take-up reel 32 provides storage space for the retraction of the enclosure panel 3, making the retraction of the enclosure panel 3 more orderly, avoiding damage caused by random stacking of the enclosure panel 3, and facilitating the next unfolding and use, thus improving the cleanliness and service life of the equipment.

[0035] Furthermore, such as Figure 4 As shown, a torsion spring 322 is installed on the positioning shaft 321. The torsion spring 322 is used to drive the enclosure piece 3 to rewind and reset.

[0036] The torsion spring 322 on the positioning shaft 321 deforms and stores elastic potential energy when the enclosure panel 3 unfolds. When the enclosure panel 3 needs to be retracted, the torsion spring 322 releases the elastic potential energy to drive the winding wheel 32 to rotate, thereby achieving automatic winding and resetting of the enclosure panel 3. The effect is that the automatic resetting function of the torsion spring 322 enables the enclosure panel 3 to be quickly and automatically wound up when the lifting rod 31 descends, without manual assistance, further improving the convenience of equipment operation, while ensuring uniform winding force and avoiding uneven winding of the enclosure panel 3.

[0037] Furthermore, the enclosure panel 3 is made of flexible rubber material and has a sponge layer on its surface.

[0038] The baffle 3 is made of flexible rubber material with a sponge layer on its surface. The flexible material has good elasticity and deformation capacity, while the sponge layer provides cushioning. The effect is that the combination of flexible rubber material and sponge layer can minimize rigid contact between the baffle 3 and the tobacco leaves, and act as a buffer when the tobacco leaves sway, effectively preventing the tobacco leaves from being scratched or squeezed and damaged, significantly improving the protection effect on the tobacco leaves and ensuring the quality of the tobacco leaves.

[0039] In use, the tobacco leaf anti-scratching conveying and transporting equipment of this utility model first removes the detachable top cover 5. By controlling the screw motor 24 to reverse, the screw 22 drives the screw slider 23 and the lifting rod 31 to descend. At this time, the torsion spring 322 on the positioning shaft 321 releases its elastic potential energy, driving the winding wheel 32 to rotate and roll up the enclosure 3, exposing the tobacco leaf clamping rod 4 inside the protective space. The staff neatly clamps the tobacco leaves to be transported onto the tobacco leaf clamping rod 4 to ensure that the tobacco leaves are placed stably. After the tobacco leaves are placed, the screw motor 24 is started to rotate forward. The screw 22 rotates, causing the screw slider 23 to rise, which in turn moves the lifting rod 31 upward, pulling the baffle plate 3 to unfold from the take-up wheel 32. The rising height of the lifting rod 31 is adjusted according to the height and quantity of the tobacco leaves, ensuring that the protective space formed inside the baffle plate 3 precisely covers the tobacco leaves, preventing the leaves from swaying due to excessive space or being squeezed due to insufficient space. During this process, the take-up wheel 32 rotates as the baffle plate 3 unfolds, and the torsion spring 322 deforms to store elastic potential energy. After the protective space is adjusted to the correct position, the transparent glass top cover 5 is placed on the support block 25 on top of the adjusting component 2 to seal the top of the protective space. Workers hold the handle 6 on the outside of the adjusting component 2 and push the equipment via the casters 11 at the bottom of the base 1 to move and transport it in fields, curing barns, and other locations. During transport, the condition of the tobacco leaves inside can be observed at any time through the transparent top cover 5. The flexible rubber and sponge layer of the enclosure 3 effectively cushions the movement of the tobacco leaves, preventing scratches and damage. After the equipment is transferred to the target location, the top cover 5 is removed, the control screw motor 24 is reversed, the lifting rod 31 is lowered, the torsion spring 322 drives the winding wheel 32 to rewind the enclosure piece 3 back to its original position, and the staff removes the tobacco leaves from the tobacco clamp rod 4, completing the entire transfer process.

Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods.
