Description

Technical Field

[0001] This application belongs to the field of tobacco leaf processing technology, specifically relating to a double-box pneumatic baling device for tobacco leaves. Background Technology

[0002] After curing, the tobacco leaves are loose and scattered, which is not conducive to bagging, transportation, and sales. They need to be compressed and tied into bundles. To accelerate the compression process, various tobacco stations have designed and manufactured multiple pneumatic baling devices, which have generally improved work efficiency. However, some problems remain, such as: only one pressing station, requiring workers to wait during compression, thus hindering efficiency; unreasonable pneumatic switch settings, requiring bending over or moving to activate, reducing efficiency; and fixed compression volume, lacking flexibility. Summary of the Invention

[0003] This application provides a double-box pneumatic baling device for tobacco leaves to solve or partially solve the problems mentioned in the background art.

[0004] This application provides a pneumatic baling device for double-box tobacco leaves, including a mounting base. The mounting base has a mounting groove with its top and front communicating with the outside. A central partition is provided at the bottom center of the mounting groove, dividing the mounting groove into two holding grooves with their tops and fronts communicating with the outside. A first lifting mechanism is vertically mounted on the top of the central partition. A rotating beam is rotatably mounted at the top end of the lifting part of the first lifting mechanism. A holding cylinder and a hand control valve are vertically mounted on the top of the rotating beam. The output rod of the holding cylinder passes through the rotating beam, and a pressure block is provided at its bottom end. The holding cylinder is connected to an external air pump through the hand control valve. A movable pressure plate with a cross-sectional dimension adapted to the holding groove is movably mounted inside the holding groove. The pressure block and the movable pressure plate are in movable contact.

[0005] Preferably, the mounting base is provided with casters at the four corners of its bottom.

[0006] Preferably, locking seats are symmetrically arranged on the distal sidewalls of the two holding grooves. Each locking seat includes a base that is vertically disposed on the sidewall of the holding groove. A lifting groove is opened on the rear side of the top of the base. A lifting rod is slidably disposed in the lifting groove. A pressure rod is disposed on the top of the lifting rod. The base, the lifting rod, and the pressure rod form a U-shaped locking groove with the opening facing forward. The rotating beam is movably inserted into the locking groove.

[0007] Preferably, a fastening bolt is provided on the side wall of the base, and the fastening bolt spirally penetrates the side wall of the lifting groove and moves in contact with the lifting rod.

[0008] Preferably, when the rotating beam seat is inserted into the locking groove, the pressing cylinder is located at the center of the pressing groove.

[0009] Preferably, a rotating handle is provided at the top end of the rotating beam on the side away from the first lifting mechanism.

[0010] Preferably, guide grooves are symmetrically provided on the left and right side walls of the pressing groove, and the left and right sides of the movable pressure plate are slidably embedded in the guide grooves.

[0023] Example 1

[0024] like Figures 1 to 4 As shown, this application provides a pneumatic baling device for double-box tobacco leaves, including a mounting base 1. The mounting base 1 has a mounting groove with its top and front communicating with the outside. A central partition 12 is provided at the bottom center of the mounting groove. The mounting groove is divided into two holding grooves 11 with their tops and fronts communicating with the outside by the central partition 12. A first lifting mechanism 5 is vertically provided at the top of the central partition 12. A rotating beam 4 is rotatably provided at the top end of the lifting part of the first lifting mechanism 5. A holding cylinder 2 and a manual control valve 7 are vertically provided at the top of the rotating beam 4. The output rod of the holding cylinder 2 passes through the rotating beam 4 and a pressure block 21 is provided at its bottom end. The holding cylinder 2 is connected to an external air pump through the manual control valve 7. A movable pressure plate 3 with a cross-sectional size adapted to the holding groove 11 is movably provided in the holding groove 11. The pressure block 21 and the movable pressure plate 3 are in movable contact.

[0025] The rotating beam 4 drives the pressing cylinder 2 to press the tobacco leaves in the two pressing slots respectively, which is flexible and has higher compression and bundling efficiency. A manual control valve 7 is set on the rotating beam 4. After the rotating beam 4 is rotated, the manual control valve 7 can control the pressing cylinder 2 to drive the movable pressure plate 3 to press down, which conforms to the operation process and does not require moving or bending over, further improving efficiency. The height of the pressing cylinder 2 is controlled by the first lifting mechanism 5, which in turn controls its pressing height, making it easy to flexibly adjust the size of the tobacco bundle and improve the flexibility of compression and bundling.

[0026] Preferably, the mounting base 1 is provided with four casters 8 at the bottom corners, which increases the mobility of this application.

[0027] Specifically, locking seats 6 are symmetrically arranged on the distal sidewalls of the two holding grooves 11. Each locking seat 6 includes a base 61 that is vertically disposed on the sidewall of the holding groove 11. A lifting groove is provided on the rear side of the top of the base 61. A lifting rod 63 is slidably disposed in the lifting groove. A pressure rod 62 is provided on the top of the lifting rod 63. The base 61, the lifting rod 63, and the pressure rod 62 form a U-shaped locking groove with the opening facing forward. The rotating beam 4 is movably inserted into the locking groove. A fastening bolt 64 is provided on the sidewall of the base 61. The fastening bolt 64 spirally penetrates the sidewall of the lifting groove and movably abuts against the lifting rod 63.

[0028] Loosen the fastening bolt 64 and adjust the height of the lifting rod 63 so that when the rotating beam 4 is screwed into the locking groove, the top of the rotating beam 4 and the bottom of the pressure rod 62 are in close contact. When the output rod of the holding cylinder 2 drives the pressure block 21 to abut against the movable pressure plate 3, the tobacco leaves below the movable pressure plate 3 will exert a reaction force on the rotating beam 4. The two ends of the rotating beam 4 are fixed by the first lifting mechanism 5 and the pressure rod 62 respectively, maintaining the stability of the pressing process and preventing the rotating beam 4 from tilting due to unstable force when it is only fixed to one end of the first lifting mechanism 5, thus damaging its connection.

[0029] Preferably, when the rotating beam 4 is inserted into the locking groove, the pressing cylinder 2 is located at the center of the pressing groove 11, which is beneficial to the stable pressing of the movable pressure plate 3.

[0030] Preferably, a rotating handle 41 is provided at the top end of the rotating beam 4 away from the first lifting mechanism 5, so as to facilitate manual operation of the rotating beam 4.

[0031] Preferably, guide grooves 13 are symmetrically provided on the left and right side walls of the pressing groove 11, and the left and right sides of the movable pressure plate 3 are slidably embedded in the guide grooves 13. An elastic band 31 is connected to the top of the guide groove 13, and the bottom end of the elastic band 31 is connected to the movable pressure plate 3.

[0032] The guide groove 13 is used to guide the lifting and lowering of the movable pressure plate 3. The elastic band 31 facilitates the lifting and resetting of the movable pressure plate 3 after the tobacco leaf is compressed, thus avoiding instability during the lifting and lowering of the detachable movable pressure plate 3 and the waste of time due to frequent movement of the movable pressure plate 3.

[0033] The first lifting mechanism 5 is a hydraulic lifting mechanism or an electric cylinder.

[0034] Implementation principle:

[0035] Tobacco leaves are filled below the movable pressure plate 3 in the two pressure grooves 11. The rotating beam 4 is rotated to make the pressure cylinder 2 rotate into one of the pressure grooves 11, and its end rotates into the locking groove. The external air pump is controlled by the hand control valve 7 to introduce high pressure gas into the pressure cylinder 2. The pressure block of the pressure cylinder 2 drives the movable pressure plate 3 to compress the tobacco leaves. The pressure cylinder 2 is reset. The rotating beam 4 is rotated by rotating the handle 41 to make it rotate into the other pressure groove 11 to compress the tobacco leaves. The first pressure groove 11 is used for tobacco leaf replacement, which speeds up the efficiency of tobacco leaf compression and bundling.

[0036] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
