Description

Technical Field

[0001] This utility model relates to the field of paper slitting machine technology, and in particular to a staggered slitting nozzle slitting machine. Background Technology

[0002] In the cigarette manufacturing process, the production of cigarette filter rods is a crucial step. The quality of the outer layer of the filter rod paper has a significant impact on the overall quality of the cigarette. To improve the slitting quality and production efficiency of the outer layer of cigarette filter rod paper and meet the ever-evolving needs of the cigarette industry, developing a staggered slitting filter rod slitting machine is of great practical significance.

[0003] The existing slitting machine's mechanism for positioning, installing, and driving the paper rollers or paper roll shafts is not optimized enough, making the tightening and loosening of the paper rollers or paper roll shafts cumbersome and inconvenient. This indirectly reduces the efficiency of disassembling and replacing the paper rollers or paper rolls and the overall production efficiency of the slitting machine. Utility Model Content

[0004] In view of this, the present invention provides a staggered cutting nozzle slitting machine to solve the problem that the operation of loosening or tightening paper rollers or paper roll shafts is relatively troublesome and inconvenient.

[0005] The technical solution proposed by this utility model is as follows: a staggered cutting nozzle bar slitting machine, specifically including two symmetrically arranged transverse contact plates and hollow roller shafts. Vertical support rods are welded to the top of the transverse contact plates, and the vertical support rods are arranged in pairs. A circular bearing seat is welded to the top of each pair of vertical support rods on the two transverse contact plates. In each pair of bearing seats, a short rotating shaft assembly is mounted through the inner ring of a bearing embedded in one bearing seat, and a long rotating shaft is slidably mounted through the inner ring of a bearing embedded in the other bearing seat. Three L-shaped retaining rods are welded around the long rotating shaft. A baffle plate is attached, and three circumferentially distributed top clamping plates are slidably mounted on the baffle plate; a torsion drive shaft is rotatably mounted through the long rotating shaft, and the first end of the torsion drive shaft is rotatably connected to the baffle plate. The part of the torsion drive shaft that extends out of the long rotating shaft has an external thread, and a threaded sleeve is screwed onto the external thread. A connecting rod is rotatably connected between the threaded sleeve and the top clamping plate; a positioning component is slidably mounted on the vertical support rod in the form of a spring push, and the positioning component is used to insert and position the long rotating shaft; the two ends of the top of the hollow roller shaft are respectively fitted into the part of the short rotating shaft assembly that protrudes into the bearing seat and is placed inside the bearing seat and the three circumferentially distributed top clamping plates.

[0006] Furthermore, the top clamping plate is pressed against the inner circumference of the hollow roller shaft, and a rubber pad adapted to its shape is fixed on the outer side of the top clamping plate. The rubber pad is pressed and clamped between the top clamping plate and the inner circumference of the hollow roller shaft.

[0007] Furthermore, the short shaft assembly has an I-shaped cross-section structure, and a rubber sleeve is fixed to the part of the short shaft assembly that protrudes from the inner side of the bearing seat;

[0008] When the hollow roller shaft is fitted into the short rotating shaft assembly, the rubber sleeve and the inner circumference of the hollow roller shaft come into frictional and compressive contact.

[0009] Furthermore, the baffle plate has three circumferentially distributed sliding grooves, and the tail end of the top plate is integrally formed with a T-shaped slider. The T-shaped slider slides in conjunction with the sliding grooves, and the tail end of the T-shaped slider is fixedly connected to a U-shaped connector.

[0010] The two ends of the connecting rod are rotatably connected to the outer circumference of the threaded sleeve and the U-shaped connector, respectively.

[0011] Furthermore, a small-diameter centering shaft is fixedly connected to the first end of the rotary drive shaft, and the small-diameter centering shaft is rotatably connected to the center part of the baffle.

[0012] Furthermore, the tail end of the long rotating shaft is integrally formed with a thin bushing and a limiting ring, and an annular positioning groove is formed between the limiting ring and the long rotating shaft at intervals.

[0013] Furthermore, two horizontally mounted mounting plates are welded to the vertical support rod at intervals. A U-shaped sliding frame is slidably mounted through the two horizontally mounted mounting plates. A limit plate is integrally formed inside the U-shaped sliding frame, and a semi-circular limit ring is integrally formed at the top of the U-shaped sliding frame. The semi-circular limit ring is inserted into and cooperates with the annular positioning groove.

[0014] The positioning component is composed of a U-shaped sliding frame and a semi-circular limiting ring welded together. The spring that pushes the positioning component is fitted onto the U-shaped sliding frame and is compressed and clamped between the limiting plate and the horizontal mounting plate on the lower side.

[0015] The staggered cutting nozzle slitting machine provided by this utility model has the following beneficial effects:

[0016] 1. The rubber pad can increase the frictional resistance when the top plate and the hollow roller shaft are in tight contact, thereby improving the stability of the transmission connection between the long rotating shaft and the hollow roller shaft.

[0017] 2. In this utility model, simply rotating the rotary drive shaft drives the three top clamping plates to separate from the hollow roller shaft, and controlling the semi-circular limiting ring to separate from the annular positioning groove by pulling down the U-shaped sliding frame, can unlock the long rotating shaft and the hollow roller shaft, and release the long rotating shaft to separate the long rotating shaft and the hollow roller shaft, thus severing the transmission connection between the long rotating shaft and the hollow roller shaft and the positioning of the hollow roller shaft by the long rotating shaft. This allows for the extraction, disassembly, and replacement of the fully loaded hollow roller shaft and the paper roll on it. Thus, in this utility model, only the above two simple operations are needed to unlock and release the hollow roller shaft to meet the conditions for disassembly and replacement of the hollow roller shaft. The operation is simple and time-saving, which helps to indirectly improve the efficiency of disassembly and replacement of the hollow roller shaft. Attached Figure Description

[0047] Implementation 2: This embodiment is based on Implementation 1, but with the following additions:

[0048] This embodiment includes,

[0049] Hollow rollers 8 are rotatably positioned between two bearing seats 103 at corresponding longitudinal positions, and there are three such seats in total. Three sets of vertical support rods 102 are arranged at the top of each horizontal contact plate 1. Sprockets 12 are fixedly mounted on the protruding portions of two short rotating shaft assemblies 9 within two adjacent bearing seats 103. Drive units 11 are fixedly installed on the inner sides of the two sets of vertical support rods 102 corresponding to the positions of these two short rotating shaft assemblies 9. Sprockets 12 are fixedly mounted on the power output shaft of the drive unit 11, and chains 7 are mounted on all three sprockets 12. An electrical control box 10 is fixedly mounted on one set of vertical support rods 102, and the electrical control box 10 contains an electrical control unit for controlling the start and stop of the drive unit 11. Two hollow rollers 8 are arranged at close proximity. Two rows of paper rolls 4 are arranged around the shaft, with an odd and even number of rolls respectively, and the two rows of paper rolls 4 are arranged in an alternating manner. A paper roller 3 is arranged around the remaining hollow roller shaft 8. A U-shaped vertical support frame 101 is arranged in the space between the paper roller 3 and the paper roll 4. The bottom end of the U-shaped vertical support frame 101 is welded and fixed to the horizontal contact plate 1. A row of equally spaced cutting blades 2 is fixedly suspended below the top side rod of the U-shaped vertical support frame 101. The inner ring of the bearing of the short rotating shaft assembly 9 is integrally formed with two symmetrically distributed transmission key strips 1031. Two keyways 605 are symmetrically opened on the outer circumference of the long rotating shaft 6. The transmission key strips 1031 slide with each other. The long rotating shaft 6 is driven by the bearing through the two keyways 605 and the transmission key strips 1031.

[0050] The working principle, specific details, implementation steps, functions and interrelationships of the features in the above embodiments, and the roles these features play in realizing this technical solution will be described and explained in detail below:

[0051] Paper roller 3 is made of uncut outer packaging paper used to manufacture cigarette filter rods. Paper roll 4 is formed by winding strips of paper cut from the paper roller. Cutting blade 2 pierces the paper pulled from paper roller 3 and uses the traction conveying force of paper roll 4 to cut the paper into strips. Hollow roller shaft 8 rotates between two bearing seats 103 via short rotating shaft assembly 9, long rotating shaft 6, and two bearings assembled with them. Through the meshing transmission of chain 7 and three sprockets 12, drive unit 11 can drive the two hollow roller shafts. The rotation of the core roller 8 and the two rows of paper rolls 4 enables the two rows of paper rolls 4 to pull and convey the raw paper, and to cut the raw paper using a row of cutting blades 2. The cut strips of paper can be rotated and wound up. Since the two rows of paper rolls 4 are staggered and set in odd and even numbers respectively, the even-numbered paper rolls 4 can wind up the even-numbered strips of paper, and the odd-numbered paper rolls 4 can wind up the odd-numbered strips of paper. In this way, the two rows of paper rolls 4 can classify and wind up the strips of paper cut by staggered odd and even numbers.

[0052] The threaded sleeve 604, three connecting rods 606, and three clamping plates 607 are connected to form a three-crank slider mechanism. Through this mechanism, the forward and reverse rotation torque drive shaft 601 can be threaded to drive the threaded sleeve 604 to slide toward or away from the long rotating shaft 6. The drive control and the three clamping plates 607 slide synchronously inward and outward, and press against or separate from the inner circumference of the end of the hollow roller shaft 8. This connects the long rotating shaft 6 and the hollow roller shaft 8 to a tight transmission connection or releases the long rotating shaft 6 and the hollow roller shaft 8 to decouple the power. The part of the hollow roller shaft 8 that is fitted with the short rotating shaft assembly 9 is transmitted to the short rotating shaft assembly 9 through the frictional extrusion force applied to the rubber sleeve 901. The rubber pad 6071 can increase the frictional resistance when the clamping plate 607 and the hollow roller shaft 8 are in tight contact, thereby improving the stability of the transmission connection between the long rotating shaft 6 and the hollow roller shaft 8.

[0053] When the semicircular limiting ring 501 is inserted into the annular positioning groove, the long rotating shaft 6 can be positioned to slide towards the hollow roller shaft 8 and be connected to the hollow roller shaft 8 in a driving state. The semicircular limiting ring 501 is kept in the inserted positioning state by the spring push on the U-shaped slide frame 5.

[0054] In this invention, simply rotating the rotary drive shaft 601 drives the three clamping plates 607 to separate from the hollow roller shaft 8, and controlling the semicircular limiting ring 501 to be pulled out of the annular positioning groove by pulling down the U-shaped sliding frame 5, can unlock the long rotating shaft 6 and the hollow roller shaft 8, and release the long rotating shaft 6 to separate the long rotating shaft 6 and the hollow roller shaft 8, thus terminating the transmission connection between the long rotating shaft 6 and the hollow roller shaft 8 and the positioning of the hollow roller shaft 8 by the long rotating shaft 6. This allows for the extraction, disassembly, and replacement of the fully loaded hollow roller shaft 8 and the paper roll 4 on it. Thus, in this invention, only these two simple operations are needed to unlock and release the hollow roller shaft 8 to meet the conditions for disassembly and replacement of the hollow roller shaft 8. The operation is simple and time-saving, which helps to indirectly improve the efficiency of disassembly and replacement of the hollow roller shaft 8.

[0055] It is worth noting that the composition of the electronic control unit, its connection and wiring method with the drive unit 11, and its control principle for the electronic control unit are existing technologies for those skilled in the art who are engaged in equipment electrification design, modification, and testing, and therefore will not be elaborated here.
