[0001] The invention belongs to the technical field of tobacco processing equipment, and in particular relates to a tobacco sheet separation device. Background Art

[0002] With the widespread use of high-speed cigarette making machines, cigarette factories have higher and higher requirements for the uniformity of tobacco leaves. At present, many cigarette factories have realized this problem and put the uniformity of tobacco leaves on the work schedule. In the process of tobacco leaf processing, tobacco leaf screening is an important link. The purpose of screening is to screen out large pieces of tobacco leaves for separate processing, which will reduce the crushing of tobacco leaves, reduce tobacco leaf consumption in the production process, and reduce production costs.

[0003] The main screening method for tobacco leaves at present is vibrating screening equipment. Due to the large mass of tobacco leaves, the screen is usually formed by opening round holes on the plate, and woven screens are generally not used. The disadvantages of this type of screen are that tobacco leaves are easy to clog the screen during the screening process, and the screening effect will gradually decrease during use, and the screen will be clogged, resulting in low screening efficiency. The size of the screen hole cannot be adjusted, and the entire screen needs to be replaced when changing the screening accuracy. Summary of the invention

The rods are transmission connected, the scraper plate includes a baffle and an inclined plate, the inclined plate is hingedly mounted on the baffle, a reserved groove corresponding to the sieve hole is provided on the baffle, traction columns are provided at both ends of the inclined plate, a connecting plate is installed at the bottom end of the baffle, the connecting plate is fixedly installed on the linkage rod, a notch is provided on the oblique plate, the linkage rod is located in the notch, sieve holes are provided on the side plate, the first splicing plate and the second splicing plate, the sieve holes on the first splicing plate and the second splicing plate are staggered, a lifting and adjusting mechanism is installed on the outer frame, and the traction column is slidably carded in the lifting and adjusting mechanism.

[0007] On the basis of the above scheme, the present invention also makes the following improvements:

[0008] Further, the adjustment member includes a push rod, a connecting rod and an adjustment screw, the push rod and the connecting rod are integrally formed, the adjustment screw is threadedly connected to the outer frame, the linkage rod is provided with a first transmission groove and a second transmission groove that are interconnected, the width of the first transmission groove is equal to the outer diameter of the push rod, the width of the second transmission groove is equal to the outer diameter of the connecting rod, the end of the adjustment screw is provided with a first blind hole, and the other end is provided with an adjustment column, the connecting rod is penetrated in the first blind hole, the adjustment screw and the connecting rod are provided with corresponding connecting holes, and the connecting hole is penetrated with a connecting key. The adjusting screw is driven to produce horizontal displacement while rotating by rotating the adjustment key, and the push rod can produce horizontal displacement while rotating when the adjusting screw moves horizontally. Under the action of the first transmission groove and the second transmission groove, the push rod and the connecting rod can make the linkage rod move horizontally without driving the linkage rod to rotate, and the horizontally moving linkage rod can drive the scraper to move horizontally.

[0009] Furthermore, the first splicing plate and the second splicing plate are both provided with rounded corners at the top of the sieve hole, so that the top of the sieve hole is smoother and the tobacco leaves can fall into the sieve hole better during the screening process.

[0010] Furthermore, two oppositely arranged bases are installed on the inner walls of both sides of the outer frame, and a fixing rod is detachably installed on the outer frame, and the side panels, the first splicing panel and the second splicing panel are all installed between the base and the fixing rod. The side panels, the first splicing panel and the second splicing panel are supported by the base, and then fixed by the fixing rod, so that during installation, the side panels, the first splicing panel and the second splicing panel can be directly placed on the base and then fixed by the fixing rod, which is convenient for installation and easy to use.

[0011] Furthermore, the base is provided with a first mounting slot, a second mounting slot and an adjusting slot, the lifting and adjusting mechanism includes a top plate and a pressure plate, the traction column is located between the top plate and the pressure plate and is in sliding contact with the top plate and the pressure plate, the width of the pressure plate is smaller than the width of the top plate, a plurality of limit columns are provided at the bottom end of the top plate, the base is provided with limit holes matching the limit columns, the limit columns are slidably penetrated into the limit holes, the side walls at both ends of the top plate are provided with a first traction slot and a second traction slot, the pressure plate is fixedly provided with a first stud, the first stud is installed with a traction plate and a fastening nut, the traction plate is located in the first traction slot, the fastening nut is located at the lower part of the top plate, the base is threaded with a second stud in the adjusting slot, and the top end of the second stud is ball-jointed to the top plate. The top plate and the pressure plate are driven to move up and down by the second stud. Since the traction column on the inclined plate is located between the top plate and the pressure plate, when the heights of the top plate and the pressure plate change, the traction column will slide between the top plate and the pressure plate to change the angle of the inclined plate, thereby realizing the adjustment of the angle of the inclined plate, and then changing the angle of the inclined plate according to actual conditions during use, to avoid the inclined plate maintaining the original inclined angle to move and block the sieve holes when the scraper plate causes the moving sieve holes to be blocked by the baffle plate, resulting in the tobacco leaves being difficult to fall out of the sieve holes during the screening process and causing blockage. A reserved groove corresponding to the sieve holes is provided on the baffle plate.

[0012] Furthermore, the two ends of the fixing rod are respectively provided with a second blind hole, the upper end of the fixing rod is provided with a slide groove connected with the second blind hole, a lock pin is slidably installed in the second blind hole, a spring is provided between the lock pin and the bottom of the second blind hole, a lever is passed through the slide groove, the lever is fixedly connected with the lock pin, and a through hole corresponding to the lock pin is provided on the outer frame. The locking pin is pushed out by the spring and inserted into the through hole so that the fixing rod is fixed to the outer frame, and when it needs to be disassembled, the lever can be pulled, so that the installation and disassembly of the fixing rod are relatively convenient.

[0013] Furthermore, a slot is provided on the inclined plate, and a load-bearing beam corresponding to the slot is installed on the outer frame. The load-bearing beam supports the middle of the first splicing plate and the second splicing plate to prevent the middle of the first splicing plate or the second splicing plate from sinking when the tobacco leaves are heavy.

[0014] Furthermore, the load-bearing beam and the linkage rod are both located between two adjacent sieve holes on the first splicing plate, and the load-bearing beam is located between two adjacent sieve holes on the second splicing plate, so as to avoid the load-bearing beam and the sieve hole overlapping, resulting in the lower end of the sieve hole being blocked by the load-bearing beam, causing tobacco leaves to block the sieve hole during the screening process.

[0015] Beneficial effects of the present invention:

[0016] 1. Both the first splicing plate and the second splicing plate are provided with inclined inclined plates. During the oscillating screening process, since the motion trajectory of the screen is fixed and the tobacco leaves oscillate irregularly during screening, the tobacco leaves that fall into the screen holes hit the inclined plates, so that the inclined plates can better take out the tobacco leaves that fall into the screen holes, which can better prevent the tobacco leaves from clogging the screen holes;

[0017] 2. The scraper plate can be driven to move by the linkage rod, so that the baffle plate slides in the first connecting groove and the second connecting groove to cover the sieve hole, so that the size of the exposed part of the sieve hole can be adjusted, thereby adjusting the screening accuracy of the screen;

[0018] 3. The height of the traction column on the inclined plate is adjusted by the lifting and adjusting mechanism. Since the traction column on the inclined plate is slidably installed on the lifting and adjusting mechanism, when the lifting and adjusting mechanism changes the height of the traction column, the traction column will slide on the lifting and adjusting mechanism to change the angle of the inclined plate, thereby adjusting the angle of the inclined plate. Then, the angle of the inclined plate can be changed according to actual conditions during use, so as to avoid the inclined plate maintaining the original tilt angle to move and block the sieve hole when the scraper plate blocks the movable sieve hole by the baffle plate, which makes it difficult for tobacco leaves to fall out of the sieve hole during the screening process and causes blockage;

[0019] 4. The screen is formed by combining the side plate, the first splicing plate and the second splicing plate. When it is partially damaged, the damaged first splicing plate and the second splicing plate can be disassembled and replaced without replacing the entire part, thereby reducing costs. At the same time, compared with the screen of the integral structure, the production and manufacturing of the combined screen is relatively easy. BRIEF DESCRIPTION OF THE DRAWINGS

The horizontally moving linkage rod 63 can drive the scraper 6 to move horizontally.

[0043] Specifically, two oppositely arranged bases 12 are installed on the inner walls on both sides of the outer frame 1, and two fixing rods 5 are detachably installed on the outer frame 1, and the two fixing rods 5 are respectively located above the two bases 12, and the side panels 3, the first splicing panel 2 and the second splicing panel 4 are all installed between the base 12 and the fixing rods 5. The side panels 3, the first splicing panel 2 and the second splicing panel 4 are supported by the base 12, and then fixed by the fixing rods 5, so that during installation, the side panels 3, the first splicing panel 2 and the second splicing panel 4 can be directly placed on the base 12 and then fixed by the fixing rods 5. It is easy to install and easy to use.

[0044] Specifically, the base 12 is provided with a first mounting groove 121, a second mounting groove 122 and an adjustment groove 123, the lifting and adjusting mechanism includes a top plate 81 and a pressure plate 82, the traction column 622 is located between the top plate 81 and the pressure plate 82 and the pressure plate, and is in sliding contact with the top plate 81 and the pressure plate 82, the width dimension of the pressure plate 82 is smaller than the width dimension of the top plate 81, a plurality of limiting columns 811 are provided at the bottom end of the top plate 81, limiting holes matching the limiting columns 811 are provided on the base 12, the limiting columns 811 are slidably penetrated in the limiting holes, the side walls at both ends of the top plate 81 are provided with a first traction groove 812 and a second traction groove 813, and the pressure plate 82 is fixedly provided with a first stud 8 3. The first stud 83 is installed with a traction plate 831 and a fastening nut 832. The traction plate 831 is located in the first traction groove 812, and the fastening nut 832 is located at the lower part of the top plate 81. The base 12 is screwed with a second stud 124 in the adjustment groove 123. The top end of the second stud 124 is ball-jointed on the top plate 81. Since the width of the pressure plate 82 is smaller than the width of the top plate 81, when installing the leaf hanging plate 6, the fastening nut 832 can be loosened first, and then the pressure plate 82 can be pulled to slide by the first stud 83 to prevent the pressure plate 82 from blocking the traction column 622 on the inclined plate 62. After the leaf hanging plate 6 is placed, the pressure plate 82 is reset to press all the traction columns 622. The top plate 81 and the pressure plate 82 are driven to move up and down by the second stud 124. Since the traction column 622 on the inclined plate 62 is located between the top plate 81 and the pressure plate 82, when the heights of the top plate 81 and the pressure plate 82 change, the traction column 622 will slide between the top plate 81 and the pressure plate 82 to change the angle of the inclined plate 62, thereby adjusting the angle of the inclined plate 62, and then changing the angle of the inclined plate according to actual conditions during use, to avoid the inclined plate 62 maintaining the original inclination angle to move and block the sieve hole 21 when the scraper plate 6 causes the movable sieve hole 21 to be blocked by the baffle 61, resulting in the tobacco leaves being difficult to fall out of the sieve hole 21 during the screening process, causing blockage.

[0045] Specifically, second blind holes 51 are respectively provided at both ends of the fixing rod 5, a slide groove 52 connected to the second blind hole 51 is provided at the upper end of the fixing rod 5, a locking pin 53 is slidably installed in the second blind hole 51, a spring 55 is provided between the locking pin 53 and the bottom of the second blind hole 51, a lever 54 is passed through the slide groove 52, and the lever 54 is fixedly connected to the locking pin 53, and a through hole 13 corresponding to the locking pin 53 is provided on the outer frame 1, the locking pin 53 is pushed out by the spring 55 and inserted into the through hole 13 so that the fixing rod 5 is fixed to the outer frame 1, and when disassembly is required, the lever 54 can be pulled, so that the installation and disassembly of the fixing rod 5 are relatively convenient.

[0046] Specifically, a slot 621 is provided on the inclined plate 62, and a load-bearing beam 15 corresponding to the slot 621 is installed on the outer frame 1. The load-bearing beam 15 supports the middle parts of the first splicing plate 2 and the second splicing plate 4 to prevent the middle parts of the first splicing plate 2 or the second splicing plate 4 from sinking when the tobacco leaves are heavy.

[0047] Specifically, the load-bearing beam 15 and the linkage rod 63 are both located between two adjacent sieve holes 21 on the first splicing plate 2, and the load-bearing beam 15 is located between two adjacent sieve holes 21 on the second splicing plate 4, so as to avoid the load-bearing beam 15 and the sieve hole 21 overlapping, resulting in the lower end of the sieve hole 21 being blocked by the load-bearing beam 15, causing tobacco leaves to block the sieve hole 21 during the screening process.

[0048] During installation, pull the lever 54 to compress the spring 55 so that the locking pin 53 is disengaged from the through hole 13, remove the fixing rod 5 from the outer frame 1, and then alternately place the first splicing plate 2 and the second splicing plate 4 on the base 12 on the outer frame 1, and at the same time, make the card slot 621 clamped on the load-bearing beam 15, and then place the side plate 3 on the load-bearing beam 15, and then pull the lever 54 to compress the spring 55 so that the locking pin 53 is located in the second blind hole 51, and place the fixing rod 5 on the upper ends of the side plate 3, the first splicing plate 2 and the second splicing plate 4, release the lever 54 to make the lever 54 clamped in the through hole 13, and complete the fixing of the two ends of the side plate 3, the first splicing plate 2 and the second splicing plate 4, and complete the combination, and then install the combined screen on the oscillation device for use;

[0049] When the screening accuracy of the screen needs to be adjusted, the adjusting key is turned to drive the adjusting screw 73 to produce horizontal displacement while rotating. When the adjusting screw 73 moves horizontally, the top rod 71 is horizontally displaced while rotating. Under the action of the first transmission groove 631 and the second transmission groove 632, the top rod 71 and the connecting rod 72 can make the linkage rod 63 move horizontally without driving the linkage rod 63 to rotate. The horizontally moving linkage rod 63 can drive the scraper 6 to move horizontally, so that the baffle 61 gradually slides from the first connecting groove 22 into the second connecting groove 63. The sieve hole 21 is blocked in the second connecting groove 23 to adjust the screening accuracy of the sieve; then the second stud 124 is rotated as needed to drive the top plate 81 to descend, and the pressure plate 82 is driven down under the action of the first stud 83 and the traction plate 831, thereby driving the traction column 622 to descend, changing the inclination angle of the inclined plate 62 to prevent the scraper plate 6 from causing the movable sieve hole 21 to be blocked by the baffle 61, and the inclined plate 62 maintains the original inclination angle to move and block the sieve hole 21, resulting in the tobacco leaves being difficult to fall out of the sieve hole 21 during the screening process, causing blockage.
