Description

Technical Field

[0001] The invention belongs to the technical field of tobacco production equipment, and in particular relates to a novel shredded material recovery system. Background Art

[0002] The shredding process of tobacco leaves mainly uses shredder equipment. Before the tobacco leaves enter the knife gate for cutting, the shredder will first pass through the compaction system. The tobacco leaves are pressed into "tobacco cakes" in the compaction system and transported to the knife gate for cutting. However, during the compaction and transportation process, the gap between the frame wall panel and the copper chain will cause some broken tobacco and tobacco dust to fall into the inner surface of the copper chain ring. After multiple rollings by the active and passive rollers, they enter the connection part of the chain plate; or hard tobacco scales are formed in the chain buckle groove. Long-term accumulation will cause the copper chain to deviate, and the transmission shaft meshing teeth will arch and jump, which is easy to cause friction and collision with the lower knife gate, seriously affecting the stability and service life of the equipment.

[0003] One of the existing treatment methods for the soot formed is to perform manual maintenance after the production is completed. Another treatment method is to reduce the gap between the wall panel and the chain. When manual maintenance is selected, due to the long production time of the equipment, the maintenance time is insufficient, and the maintenance needs to be performed when the chain is started, which poses a great safety hazard and does not comply with safety operating procedures. When reducing the gap between the wall panel and the chain, due to the mechanical movement of the copper chain, considering the offset error of the movement of the copper chain during the transmission process, a reasonable gap is a necessary design condition. After statistics, experiments and calculations, the equipment operation accuracy is adjusted to the optimal state. The gap between the copper chain and the wall panel needs to be as large as 0.8-1mm to ensure that the equipment operation is not affected. Therefore, the method of reducing the gap is not widely applicable.

[0004] In summary, the fundamental reason for the instability of the equipment is the falling of the tobacco leaves inside. It is urgent to develop a new material recovery system to solve the above technical problems. Summary of the invention

[0005] In order to solve the above technical problems existing in the prior art, the present invention provides a new material recovery system. The present invention can realize the clean recovery of tobacco leaves and tobacco foam that fall into the copper chain; it can not only reduce the tobacco leaves that fall into the chain, improve the stability of the compaction system operation, but also recover these tobacco leaves and add them back to the production line, reducing material loss in tobacco production, while ensuring the stability of equipment operation, improving productivity and reducing loss.

[0006] The technical solution adopted by the present invention is:

[0008] The purging and recovery device comprises a blowing pipe (6). When the three-position five-way solenoid valve Y1 is energized, the cylinder drives the upper copper chain and the upper knife gate seat to be pressed downward. At the same time, the compressed air is sequentially delivered to the blowing pipe (6) through the one-way valve (61), the pneumatic three-element (62), the two-position three-way solenoid valve (63) and the stop valve (64). The other end of the blowing pipe (6) is connected to the wallboard of the copper chain (11) through a threaded M6 air pipe. The purging port of the blowing pipe (6) is flush with the wallboard, and the height of the purging port is the same as the loose edge of the copper chain so that the compressed air can be blown flat into the loose edge of the copper chain. An embedded collection bag (7) is arranged opposite the purging port. The lower part of the embedded collection bag (7) is connected to a negative pressure pipeline, so that the material in the embedded collection bag (7) can be recovered by negative pressure.

[0009] Furthermore, the gap distance between the guide trough (2) and the cross arm wallboard (1) in the vertical direction is 20 mm.

[0010] Furthermore, the three smoke dust collecting ports (4) are arranged in a triangular shape, with two large ports and one small port. The areas of the smoke dust collecting ports (4) are designed according to the production flow rate and the quality of the cleaned materials.

[0012] Furthermore, the purge port of the blowing pipe is installed on one side of the wall panel.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 2. The present invention effectively avoids the generation of cigarette dust scale, reduces the deviation and jumping of the copper bar chain, and improves the operating stability of the compaction and conveying system of the shredder.

[0016] 3. The present invention can achieve the required cleaning effect by adjusting the pressure of compressed air according to different material characteristics and required results; at the same time, the falling materials are recovered into the equipment through the collection bag and the negative pressure recovery device, which reduces material loss and improves the intelligence level of the equipment.

[0024] The specific implementation of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.

[0025] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0026] The present invention will be described in detail below in conjunction with exemplary embodiments with reference to the accompanying drawings.

[0027] refer to Figures 1 to 7A novel shredded material recovery system of the present invention comprises a cross arm wall panel 1, a guide trough 2, a wear-resistant plate and a purge recovery device. An arched threaded hole is arranged below the cross arm wall panel 1, and the cross arm wall panel 1 is fixed to the exterior wall panel 3 through the arched threaded hole; the guide trough 2 is located below the cross arm wall panel 1, and there is a gap between the guide trough 2 and the cross arm wall panel 1 in the vertical direction; the guide trough 2 is a V-shaped guide cross plate, and the elbow part of the V-shaped guide cross plate is in close contact with the wear-resistant plate. The lower end of the plate 5; three smoke dust collecting ports 4 are arranged in the middle of the wear-resistant plate 5, the tight edge of the copper bar chain is arranged on the wear-resistant plate, and the rack supporting the copper bar chain is arranged in 3 layers, and the wear-resistant plate is fixed to the first layer rack 8 by screws; the loose edge of the copper bar chain is arranged in the middle of the second layer rack 9 and the third layer rack 10, and does not contact the second layer rack 9 and the third layer rack 10; the first layer rack 8 has three corresponding blanking ports corresponding to the three smoke dust collecting ports 4;

[0028] Specifically, most of the tobacco leaves falling from the gap between the copper chain and the frame can be directly guided into the lower copper chain area, and the other end of the guide plate exceeds the loose edge of the copper chain to prevent the fallen tobacco dust and broken tobacco leaves from falling into the inner surface of the copper chain ring.

[0029] The purge recovery device includes a blow pipe 6. The three-position five-way solenoid valve Y1 is energized, and the cylinder drives the upper copper chain and the upper knife gate seat to press down. At the same time, the compressed air is sequentially delivered to the blow pipe 6 through the one-way valve 61, the pneumatic three-element 62, the two-position three-way solenoid valve 63 and the stop valve 64. The other end of the blow pipe 6 is connected to the wallboard of the copper chain 11 through a threaded M6 air pipe. The purge port of the blow pipe 6 is flush with the wallboard, and the height of the purge port is the same as the loose edge of the copper chain, so that the compressed air is blown flat into the loose edge of the copper chain. A recessed collection bag 7 is arranged opposite the purge port. The lower part of the recessed collection bag 7 is connected to a negative pressure pipeline, so that the material in the recessed collection bag 7 can be recovered by negative pressure. This installation method can disassemble the collection bag, and at the same time, a negative pressure pipeline is connected to the lower part of the collection bag, so that the material in the collection bag can be recovered by negative pressure.

[0030] Specifically, the air source of the equipment itself is used, and the electromagnetic switch and three-way pipeline are installed to automatically open and close the purge device. The purge port is installed on one side of the wall panel and connected to the wall panel of the copper chain through a threaded M6 air pipe quick connector. To prevent the thread of the air pipe quick connector from colliding with the uneven copper chain, the purge port is flush with the wall panel, and the height of the purge port is the same as the loose edge of the copper chain, so that the compressed air is blown flat inside the loose edge of the copper chain. At the same time, a collection bag is installed on the other side. The collection bag is fixed to the frame through a self-designed mounting bracket and connected to the negative pressure pipeline. When the purge is started, the compressed air is sprayed through the electromagnetic valve, the purge pipeline, and the purge hole to blow the falling material inside the copper chain to the collection bag on the other side. The collection bag is to ensure that the compressed air can blow each chain link horizontally during the movement of the lower copper chain, and the blown ash is blown into the ash collection bag. The tobacco leaves in the collection bag are re-sucked into the upper chain through the negative pressure equipment that is turned on at a fixed time and returned to the production line. In order to avoid dust inside the copper chain caused by excessive wind speed during the whole process, the compressed air is limited to a maximum of 2 bar. At the same time, the electrical control program is designed to control the purge system. By detecting the linkage signal of the copper chain drive shaft of the equipment, the opening and closing of the purge system are set to ensure that the purge action is correct and does not cause energy waste.

[0031] In one embodiment, the gap distance between the material guide trough 2 and the cross arm wall panel 1 in the vertical direction is 20 mm.

[0032] In one embodiment, the three smoke dust collecting ports 4 are arranged in a triangular shape, with two large and one small. The area of ​​the smoke dust collecting ports 4 is designed according to the production flow rate and the quality of the cleaned falling materials.

[0033] In one embodiment, the three smoke dust collecting ports 4 are provided with one opening of 100*300 mm and two openings of 50*150 mm, with a front and rear interval of 200 mm.

[0034] Specifically, this design can ensure that a small number of tobacco leaves that fall into the wear-resistant plate can fall into the frame from the drop opening, while also ensuring that the wear-resistant plate has sufficient stress and does not deform.

[0035] In one embodiment, the purge port of the blow pipe is installed on one side of the wall panel.
