Description

Technical Field

[0001] This utility model relates to the field of tobacco raw material storage technology, specifically to an automatic lifting and laying device for insect-proof netting. Background Technology

[0002] Tobacco leaves and shredded tobacco are the core raw materials for cigarette manufacturing. They are usually purchased in large quantities by manufacturers during the harvest season and stored for year-round use. During storage, tobacco leaves and shredded tobacco may be eaten by insects, and these insects may also breed and excrete within the tobacco leaves and shredded tobacco, seriously affecting their quality. This not only wastes raw materials but also affects the quality of the final cigarette product.

[0003] Therefore, laying insect-proof netting has become one of the important measures to ensure the quality of tobacco products. Traditional methods of laying insect-proof netting mainly rely on manual operation, which is time-consuming, inefficient, and poses safety risks due to working at heights. Typically, insect-proof netting weighs over 20 kilograms. During the laying process, at least four workers are needed on the stack, squatting throughout to pull the netting. When the netting scrapes or rubs severely against the tobacco boxes, it needs to be adjusted back and forth, and in some areas, workers need to crawl. Four more people are needed below to pull the netting, ensuring proper spacing around the edges and reducing corner scraping. They are also responsible for moving tools and ensuring safety supervision. The upper-level work is physically demanding and requires high physical strength. To ensure smooth progress, workers at the top and bottom often switch between stacks and work surfaces, resulting in extremely low laying efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art pointed out in the background section, this utility model provides an automatic lifting and laying device for insect netting, which is safe, efficient, simple and flexible in structure, and can greatly reduce the labor intensity of workers and reduce personnel safety risks.

[0005] This utility model provides an automatic lifting and laying device for insect-proof netting, used for laying insect-proof netting on tobacco stacks. It includes: two sets of side frames, each set comprising a base and two uprights spaced apart on the base along a first direction, the tops of the two uprights connected by a connecting beam; the two sets of side frames are spaced apart along a second direction; each base has at least one caster wheel at its bottom; and a crossbeam extending along the second direction, its two ends connected to the connecting beams of the two sets of side frames respectively. The crossbeam has a width along the first direction to allow operators to stand or place the insect-proof netting. The caster wheels are adapted to support the side frames and the crossbeam under external force, allowing the crossbeam to move along the first direction and span the tobacco stack; the first direction and the second direction are perpendicular to each other.

[0006] In a possible implementation, the base includes a first crossbar and a second crossbar, the first crossbar extending along a first direction, and two second crossbars respectively connected to the two ends of the first crossbar and extending along a second direction, with a caster wheel provided at each end of the second crossbar.

[0007] In a possible implementation, the crossbeam is configured to be telescopic in the second direction.

[0008] In a possible implementation, the pole is configured to be telescopic in a direction perpendicular to the first direction and the second direction.

[0009] In a possible implementation, the side support frame further includes a lifting mechanism disposed on the base and the connecting beam, for driving the connecting beam to rise and fall.

[0010] In a possible implementation, the lifting mechanism includes a lead screw mechanism, which includes a threaded lead screw, a nut, and a motor for driving the threaded lead screw to rotate; the threaded lead screw is rotatably disposed between the base and the connecting beam, with the motor disposed on one of the base and the connecting beam and the nut disposed on the other, the nut engaging with the threaded lead screw.

[0011] In a possible implementation, the lifting mechanism includes a cylinder mechanism, with a cylinder body fixedly mounted on one of the base and the connecting beam, and the other connected to the cylinder output end.

[0012] In a possible implementation, the crossbeam and the connecting beam are detachably connected by a pin-hole fitting mechanism.

[0013] In a possible implementation, the lifting mechanism is detachably connected to the base and / or the connecting beam via a pin-hole engagement mechanism.

[0014] In a possible implementation, the side support also includes a reinforcing beam connected between the two uprights, the height of the reinforcing beam being between the base and the connecting beam, and a sleeve being provided on the reinforcing beam, through which the lifting mechanism is disposed.

[0015] According to the automatic lifting and laying device for insect-proof netting provided in this embodiment, the insect-proof netting to be laid can be temporarily placed on a crossbeam, and operators can also stand on the crossbeam. The side support frame raises the crossbeam above the stack, and the operator on the ground pushes the device. With the help of casters, the device can easily move in all directions, allowing the crossbeam to cross the stack and lay the insect-proof netting over it. In this process, the weight of the insect-proof netting is mainly borne by the crossbeam, reducing the number of personnel required on the crossbeam, and reducing the range of motion and force exerted, thus greatly reducing safety risks. In addition, the device is easy to move; it can be moved to the corresponding work position as needed, and can also be easily pushed to other positions when not in use. Attached Figure Description

Figure 1-3 As shown: An automatic lifting and laying device 100 for insect-proof netting includes: two sets of side frames 10, each set of side frames 10 including a base 11 and two uprights 12 spaced apart on the base 11 along a first direction, the top ends of the two uprights 12 being connected by a connecting beam 13, the two sets of side frames 10 being spaced apart along a second direction, and each base 11 having at least one caster wheel 111 at its bottom; a crossbeam 20 extending along the second direction, with its two ends respectively connected to the connecting beams 13 of the two sets of side frames 10, the crossbeam 20 having a width along the first direction for operators to stand on or stack insect-proof netting; wherein, the caster wheel 111 is adapted to carry the side frames 10 and the crossbeam 20 to move along the first direction under the action of external force, and to allow the crossbeam 20 to cross tobacco stacks; the first direction and the second direction are perpendicular to each other.

[0024] According to the automatic lifting and laying device 100 for insect-proof netting provided in this embodiment of the present invention, the insect-proof netting to be laid can be temporarily placed on the crossbeam 20, and the operator can also stand on the crossbeam; the side support 10 raises the crossbeam 20 above the height of the stack, and the operator standing on the ground pushes the device. With the action of the casters 111, the device can easily move in all directions, so that the crossbeam 20 can cross the stack, and the insect-proof netting is laid on the stack in the process. In this process, the weight of the insect-proof netting is mainly borne by the crossbeam, the number of personnel required on the crossbeam 20 is reduced, and the range of motion and force are reduced, greatly reducing the safety risk. In addition, the device is also easy to move, that is, it can be moved to the corresponding working position according to the work needs, and can be easily pushed to other positions when not in use.

[0025] In a possible implementation, the base 11 includes a first crossbar 112 and a second crossbar 113. The first crossbar 112 extends along a first direction, and the two second crossbars 113 are respectively connected to the two ends of the first crossbar 112 and extend along a second direction. Each end of the second crossbar 113 is provided with a caster wheel 111.

[0026] This design increases the effective lateral area of ​​the base 11, thus improving the stability of the device. On the other hand, it allows for the arrangement of more casters 111, reducing the weight borne by each caster 111 and lowering the risk of damage.

[0027] In a possible implementation, the crossbeam 20 is configured to be telescopic in the second direction. In this case, on the one hand, the length of the crossbeam can be adjusted according to the width of the stack when in use, making it more versatile; on the other hand, the size of the device can be reduced when not in use, making it easier to store.

[0028] In a possible implementation, the upright 12 is configured to be telescopic in a direction perpendicular to the first and second directions. In this case, on the one hand, during use, the height of the upright 12 can be adjusted according to the height of the stack to meet the usage requirements. At the same time, the device can also be adjusted to the minimum height required for laying, thereby reducing safety risks. On the other hand, when not in use, the size of the device can be reduced for easy storage.

[0029] In a possible implementation, the side support 10 further includes a lifting mechanism 14, which is disposed on the base 11 and the connecting beam 13, and is used to drive the connecting beam 13 to rise and fall. In this embodiment, the lifting and lowering of the device is achieved through the lifting mechanism 14, which helps to improve efficiency and reduce the labor intensity of personnel. In specific implementations, the lifting mechanism 14 can take many different forms. This application only illustrates the use of a screw mechanism and a cylinder mechanism. Those skilled in the art will understand that this function can also be achieved through other types of transmission mechanisms, which are also within the scope of this embodiment.

[0030] In a possible implementation, the lifting mechanism 14 includes a lead screw mechanism, which includes a threaded lead screw, a nut, and a motor for driving the threaded lead screw to rotate; the threaded lead screw is rotatably disposed between the base 11 and the connecting beam 13, with the motor disposed on one of the base 11 and the nut disposed on the other, and the nut engaging with the threaded lead screw.

[0031] In a possible implementation, the lifting mechanism 14 includes a cylinder mechanism, with a cylinder body fixedly mounted on one of the base 11 and the connecting beam 13, and the other connected to the cylinder output end.

[0032] In a possible implementation, the crossbeam 20 and the connecting beam 13 are detachably connected by a pin-hole fitting mechanism 30. The pin-hole fitting mechanism 30 allows for quick assembly and disassembly of the device. Combined with the telescopic features disclosed in other embodiments of this application, the size of the device can be further reduced, making it not only convenient for storage but also facilitating floor changes. For example, after disassembly, the device can be easily moved into an elevator for floor changes without requiring manual transport up stairs due to elevator access limitations.

[0033] In a possible implementation, the lifting mechanism 14 is detachably connected to the base 11 and / or the connecting beam 13 via a pin-hole engagement mechanism 30.

[0034] In a possible implementation, the side support 10 further includes a reinforcing beam 15 connected between the two uprights 12. The height of the reinforcing beam 15 is set between the base 11 and the connecting beam 13. The reinforcing beam 15 is also provided with a sleeve 151, through which the lifting mechanism 14 is disposed.

[0035] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description.
