Description

Technical Field

[0001] The invention relates to the technical field of tobacco machinery, and in particular to an automatic deviation-correcting and pushing device for a redrying tobacco box. Background Art

[0002] At present, the tobacco industry generally uses stemmed and re-baked tobacco leaves in cigarette manufacturing. In order to facilitate storage and transportation of tobacco leaves, the re-baked tobacco leaves are generally stored in cigarette boxes. The silk line is the first process in cigarette production, and the first process in the silk production process is to send the re-baked cigarette boxes to the production logistics line one box at a time by chartered trucks, and enter the next process for process processing along the roller conveyor channel.

[0003] Among them, the width dimension of the roller conveying channel is designed when the equipment is manufactured, and is basically consistent with the size of the re-drying tobacco box. It is used to prevent the re-drying tobacco box from offsetting during the conveying process and causing tilting and jamming, resulting in production interruptions and equipment failures.

[0004] However, before the cigarette boxes enter the conveying channel, they need to be transported to a platform of a production logistics line. Since the platform equipment is not designed with a correction device for the re-drying cigarette boxes, the chartered driver needs to use his eyes to visually check whether the position of the re-drying cigarette boxes is aligned with the roller conveying channel. This alignment process often requires repeated adjustments, and sometimes deviations will still occur, causing damage to the re-drying cigarette boxes and equipment failures, which is labor-intensive and time-consuming, and increases labor intensity and equipment and material risks.

[0052] like Figures 1 to 4 As shown, an embodiment of the present invention provides an automatic deviation correction and pushing device for a re-roasted tobacco box, which includes a platform 100, an adaptive adjustment mechanism 500, a push plate 211, a pushing mechanism 200, a lead screw 300, a transmission motor 400 and a correction cylinder 900; wherein, the platform 100 is provided with a storage area 110, an auxiliary transmission area 120 and a main transmission area 130 in sequence in the transmission direction of the tobacco box, a guide groove 111 is provided on the storage area 110, a sliding groove is provided on the inner wall of the guide groove 111, and limited position The auxiliary transmission area 120 is provided with a first transmission roller 121, which is driven to rotate by a first motor, and the main transmission area 130 is provided with a second transmission roller 131, which is driven to rotate by a second motor, and the length of the second transmission roller 131 is less than the length of the first transmission roller 121; the adaptive adjustment mechanism 500, the adaptive adjustment mechanism 500 includes a connecting plate 510, a positioning sleeve 520, an adjustment shaft 530 and a spring, the connecting plate 510 is fixedly arranged on the platform 100, the positioning sleeve 520 The spring is fixedly connected to the connecting plate 510, and the adjusting shaft 530 is telescopically inserted into the positioning sleeve 520. The two ends of the spring are respectively fixedly connected to the positioning sleeve 520 and the adjusting shaft 530. The end of the adjusting shaft 530 away from the positioning sleeve 520 is fixedly connected to a second limit frame 150. The two ends of the pushing mechanism 200 are respectively provided with a guide part 210 and a transmission part 220. The guide part 210 is slidably arranged in the guide groove 111, and the guide part 210 is fixedly connected to the push plate 211 after passing through the guide groove 111. The transmission part 220 0 is provided with a sliding protrusion, which is slidably arranged in the sliding groove, and a threaded hole 221 is provided on the transmission part 220; the lead screw 300 is threadedly connected with the threaded hole 221, and a first transmission wheel 310 is fixedly arranged at one end of the lead screw 300; a second transmission wheel 410 is provided on the output shaft of the transmission motor 400, and the second transmission wheel 410 is transmission-connected to the first transmission wheel 310 through a toothed belt 420; the correction cylinder 900 is symmetrically arranged on both sides of the auxiliary transmission area 120, and a correction plate 910 is provided on the piston rod of the correction cylinder 900.

[0053] During operation, the re-baked cigarette box is first transported to the storage area 110 on the platform 100, which is a flat plate surface, so that the re-baked cigarette box can be stably placed. At this time, the detection device on the platform 100 can detect the re-baked cigarette box and send a cigarette box signal. The transmission motor 400 drives the second transmission wheel 410 to rotate according to the cigarette box signal. The second transmission wheel 410 drives the first transmission wheel 310 to rotate through the toothed belt 420. Since the first transmission wheel 310 is fixedly connected to the lead screw 300, the first transmission wheel 310 can drive the lead screw 300 to rotate synchronously; since the push mechanism 200 is constrained by the sliding protrusion and the sliding groove and can only slide in the guide groove 111 without rotating, the rotational movement of the lead screw 300 can be converted into the translational movement of the push mechanism 200 through the threaded cooperation between the lead screw 300 and the transmission part 220, so that the push plate 211 connected to the guide part 210 on the push mechanism 200 can push the re-baked cigarette box to move to the auxiliary transmission area 120.

[0054] When the re-baked cigarette box is pushed to the auxiliary transmission area 120, the transmission motor 400 reverses to drive the push mechanism 200 to make a reverse return motion, so that the push mechanism 200 is reset to the initial position to prepare for pushing the next re-baked cigarette box. At the same time, the correction cylinder 900 drives its piston rod to extend so that the correction plates 910 on both sides of the auxiliary transmission area 120 gradually contact and clamp the re-baked cigarette box for correction, wherein, even if the re-baked cigarette box is slightly offset after being pushed to the auxiliary transmission area 120, the correction plates 910 on both sides of the re-baked cigarette box can correct it in the process of contacting the re-baked cigarette box, so that the re-baked cigarette box is aligned with the subsequent main transmission area 130.

[0055] After the re-drying cigarette box is calibrated, the calibration cylinder 900 drives the piston rod to make a return motion to release the re-drying cigarette box. At the same time, the first motor is started to drive the first transmission roller 121 to rotate. The first transmission roller 121 can continue to transmit the re-drying cigarette box thereon to the main transmission area 130.

[0056] When the re-drying cigarette box starts to enter the main transmission area 130, the re-drying cigarette box can enter the second transmission roller 131 between the two limit frames. The second transmission roller 131 can be driven by the second motor to transmit the re-drying cigarette box to the subsequent workstation, wherein the limit frames on both sides can limit the re-drying cigarette box to prevent the re-drying cigarette box from deflecting during the transmission to the subsequent workstation.

[0057] Among them, the first limit frame 140 on one side of the main transmission area 130 can be fixed, while the second limit frame 150 on the other side is connected to the adaptive adjustment mechanism 500. When the distance between the two limit frames is smaller than the width of the re-drying tobacco box, the re-drying tobacco box can squeeze the limit frames on both sides. After the second limit frame 150 connected to the adaptive adjustment mechanism 500 is squeezed, the adjustment shaft 530 can be squeezed into the positioning sleeve 520 to compress the spring, so that the distance between the two limit frames can meet the transmission and limitation of the current re-drying tobacco box. At the same time, since the spring can provide a reaction force to the second limit frame 150 after compression, the two limit frames can always be in contact with the re-drying tobacco box, thereby effectively preventing the transmission path of the re-drying tobacco box from being deflected. At the same time, by connecting the second limit frame 150 on one side to the adaptive adjustment mechanism 500, contact limitation of tobacco boxes of different specifications can be achieved, thereby achieving universality.

[0058] Therefore, compared with the prior art, the automatic deviation correction and pushing device for the re-drying cigarette box provided in the embodiment of the present invention realizes the automatic pushing and deviation correction of the re-drying cigarette box, and improves the transmission efficiency of the re-drying cigarette box.

[0059] The length of the second transmission roller 131 is smaller than that of the first transmission roller 121 , so that the correction cylinder 900 has enough correction space above the auxiliary transmission area 120 .

[0060] Furthermore, the automatic deviation correction and pushing device for the re-roasted tobacco box further includes a first detection mechanism 700 and a second detection mechanism 800, wherein the first detection mechanism 700 is symmetrically arranged on both sides of the storage area 110, and the second detection mechanism 800 is symmetrically arranged on both sides of the auxiliary transmission area 120. In this embodiment, the first detection mechanism 700 and the second detection mechanism 800 can both be opposing photoelectric switches.

[0061] When the re-drying cigarette box is placed in the storage area 110, the first detection mechanism 700 may be blocked by the re-drying cigarette box. At this time, the first detection mechanism 700 may send a first cigarette box signal, and the transmission motor 400 drives the pushing mechanism 200 to move according to the first cigarette box signal to push the re-drying cigarette box to the auxiliary transmission area 120 through the push plate 211.

[0062] When the re-baked cigarette box reaches the auxiliary transmission area 120, the second detection mechanism 800 is blocked by the re-baked cigarette box. At this time, the second detection mechanism 800 can send a second cigarette box signal, and the correction cylinder 900 drives the piston rod to extend according to the second cigarette box signal to drive the correction plate 910 to calibrate and clamp the cigarette box. Among them, the second detection mechanism 800 can be pre-delayed. The delay time can be the time from the piston rod of the correction cylinder 900 to the correction plate 910 completing the correction and clamping of the cigarette box. That is, when the cigarette box is calibrated, the second detection mechanism 800 sends a delay signal, and the correction cylinder 900 drives the piston rod to do a return movement according to the delay signal to release the cigarette box, so that the cigarette box can be transported to the main transmission area 130 through the first transmission roller 121 on the auxiliary transmission area 120.

[0063] Furthermore, in order to provide guidance for the movement of the pushing mechanism 200 and facilitate the positioning of the screw 300, the automatic deviation correction and pushing device of the re-roasting tobacco box also includes a reciprocating bracket 600, which is fixedly arranged on the storage area 110 of the platform 100, and a sliding space is arranged on the reciprocating bracket 600, and the transmission part 220 on the pushing mechanism 200 is slidably arranged in the sliding space; the screw 300 is rotatably connected to the reciprocating bracket 600.

[0064] Specifically, the reciprocating bracket 600 may include two symmetrically arranged short plates 610 and two symmetrically arranged long plates 620, and the short plates 610 and the long plates 620 enclose a sliding space; a through hole 611 is arranged on the short plate 610, and a connecting section 320 is arranged at the end of the lead screw 300, and the connecting section 320 is rotatably arranged in the through hole 611 through a bearing, and the connecting section 320 is fixedly connected to the first transmission wheel 310 after passing through the through hole 611, wherein the sliding groove is arranged on the long plate 620.

[0065] After the transmission part 220 on the pushing mechanism 200 cooperates with the lead screw 300 through the threaded hole 221, the sliding protrusion on the transmission part 220 can cooperate with the sliding groove on the long plate 620. Through the cooperation of the sliding groove and the sliding protrusion, the rotation of the pushing mechanism 200 can be prevented, and the rotational motion of the lead screw 300 is converted into the translational motion of the pushing mechanism 200.

[0066] Furthermore, the automatic deviation correction and pushing device of the re-roasting tobacco box also includes a first limit switch 630 and a second limit switch 640. The first limit switch 630 is arranged on the end of the reciprocating bracket 600 close to the auxiliary transmission area 120, and the second limit switch 640 is arranged on the end of the reciprocating bracket 600 away from the auxiliary transmission area 120; the pushing mechanism 200 is provided with a first impact block 230 and a second impact block 240, the first impact block 230 is in contact with the first limit switch 630, and the second impact block 240 is in contact with the second limit switch 640.

[0067] Among them, the reciprocating bracket 600 is arranged in the storage area 110 of the platform 100. When the push mechanism 200 pushes the re-baked tobacco box to move in the direction of the auxiliary transmission area 120, when the first collision block 230 on the push mechanism 200 contacts the first limit switch 630, the re-baked tobacco box is transmitted to the auxiliary transmission area 120, the first limit switch 630 sends a first in-place signal, and the transmission motor 400 rotates in the opposite direction according to the first in-place signal to control the push mechanism 200 to reversely make a return movement. During the return process, when the second collision block 240 contacts the second limit switch 640, the second limit switch 640 can send a second in-place signal, and the transmission motor 400 stops running according to the second in-place signal, so that the push mechanism 200 is in a waiting state.

[0068] Furthermore, the automatic deviation correction and pushing device of the re-drying tobacco box also includes a switch bracket, and the first limit switch 630 and the second limit switch 640 are respectively fixed to the reciprocating bracket 600 through the switch bracket; the reciprocating bracket 600 is provided with a plurality of fixing holes in the length direction, and the switch bracket is fixedly connected to the reciprocating bracket 600 through the cooperation of the fixing holes and screws.

[0069] When it is necessary to push re-roasted cigarette boxes of different sizes, the pushing stroke of the pushing mechanism 200 is not the same. In order to ensure that cigarette boxes of different sizes can be pushed to the auxiliary transmission area 120, the fixed position of the switch bracket on the reciprocating bracket 600 can be changed to adjust the distance between the first limit switch 630 and the second limit switch 640, thereby changing the timing when the first limit switch 630 and the second limit switch 640 are triggered, thereby meeting the pushing requirements for cigarette boxes of different sizes.

[0070] Furthermore, the automatic deviation correction and pushing device of the re-roasting tobacco box also includes a support block 920 and a mounting bracket 930. The support block 920 is fixedly arranged on both sides of the auxiliary transmission area 120, and the mounting bracket 930 is vertically connected to the support block 920. The correction cylinder 900 is arranged on the mounting bracket 930; a sliding hole is arranged on the support block 920, and the piston rod of the correction cylinder 900 is fixedly connected to the correction plate 910 after passing through the sliding hole; a support arm 931 is fixedly arranged below the mounting bracket 930, and a preset angle is formed between the support arm 931 and the mounting bracket 930, and the end of the support arm 931 away from the mounting bracket 930 is fixedly arranged on the platform 100.

[0071] Among them, the mounting bracket 930 extends with a set length in a direction perpendicular to the support block 920 to provide support for the correction cylinder 900 as a whole. At the same time, a support arm 931 is arranged below the mounting bracket 930 to share the force at the connection between the mounting bracket 930 and the support block 920, thereby ensuring the stability of the fixation of the correction cylinder 900.

[0072] Furthermore, the automatic deviation correction and pushing device for the redrying tobacco box further comprises a fixing bracket, a waist-shaped hole is provided on the mounting bracket 930, the fixing bracket is fixedly arranged on the mounting bracket 930 through the waist-shaped hole and the bolt, and the correction cylinder 900 is fixedly arranged on the fixing bracket. Thus, the position of the fixing bracket on the mounting bracket 930 can be easily adjusted to meet the fixed installation of correction cylinders 900 of different models.

[0073] Further, if Figure 3 As shown, the automatic deviation correction and pushing device of the re-roasting tobacco box also includes a positioning bracket 141, a positioning bolt 142, a first nut and a second nut; the first end of the positioning bracket 141 is fixedly arranged on the main transmission area 130, the second end of the positioning bracket 141 is provided with a through hole 611, and the second end of the positioning bracket 141 is aligned with the first limiting frame 140 in the horizontal direction; a screw hole is provided on the first limiting frame 140 on the side of the main transmission area 130 away from the adaptive adjustment mechanism 500, the lead screw 300 of the positioning bolt 142 passes through the through hole 611 and is fixed in the screw hole, and the nut of the positioning bolt 142 is abutted against the positioning bracket 141; the first nut and the second nut are both sleeved on the stud, the first nut is abutted against the first limiting frame 140, the second nut is abutted against the positioning bracket 141, and the second nut and the nut are respectively located on both sides of the positioning bracket 141.

[0074] When the position adjustment of the first limit frame 140 on the side of the main transmission area 130 away from the adaptive adjustment mechanism 500 is completed, the stud of the positioning bolt 142 is tightened into the screw hole on the first limit frame 140 until the nut on the positioning bolt 142 abuts against the positioning bracket 141. At this time, tighten the first nut to make the first nut abut against the first limit frame 140, and tighten the second nut at the same time to make the second nut abut against the positioning bracket 141, thereby locking the position of the limit bracket.

[0075] In order to facilitate the movement of the limiting frame relative to the main transmission area 130 , a guide block is provided on the limiting frame, and a guide groove 111 is provided on the main transmission area 130 , and the guide block and the guide groove 111 are slidably matched.

[0076] Furthermore, a guide arm 143 is provided on the limit frame, and a preset angle is formed between the guide arm 143 and the transmission direction of the redrying tobacco box. The preset angle can be 30° to 45°, and is preferably 40° in this embodiment. Thus, the slight deflection of the tobacco box can be corrected by the guide arm 143, so that the tobacco box can smoothly enter between the two limit frames.

[0077] Furthermore, a guide wheel is rotatably arranged on the limiting frame, and a wheel rim of the guide wheel protrudes from the surface of the limiting frame.

[0078] When the cigarette box is transferred between the two limit racks, the two sides of the cigarette box can contact the guide wheels respectively. As the cigarette box is transferred forward, the guide wheels can rotate due to the friction of the cigarette box, thereby avoiding sliding friction resistance between the cigarette box and the limit racks. At the same time, through the contact between the cigarette box and the guide wheels, the two sides of the cigarette box can be limited to prevent the cigarette box from shifting during the transmission process.

[0079] The automatic deviation-correcting and pushing device for a re-drying cigarette box provided in an embodiment of the present invention realizes the automatic pushing and deviation-correcting of the re-drying cigarette box, thereby improving the transmission efficiency of the re-drying cigarette box.
