Description

Technical Field

[0001] This invention relates to the field of cork paper processing technology, and in particular to an integrated device and method for cork paper rewinding and slitting. Background Technology

[0002] After the tipping paper is processed and manufactured, it needs to be slit and wound according to the specifications and dimensions customized by the customer. After being cut by multiple slitting discs, the width of each strip of tipping paper meets the requirements.

[0003] However, during the slitting process of tipping paper, the paper dust and powder remaining on the slitting disc not only serve to keep the paper warm and store heat, but also affect the cut formation when cutting the tipping paper. In addition, the paper dust and powder will adhere to the tipping paper after slitting. If the tipping paper is directly rewound into a tube after slitting, a lot of paper dust and powder will remain, and subsequent processes will require another cleaning process.

[0004] The paper dust remaining on the slitting disc mainly comes from two sources: First, when the slitting disc comes into contact with the tipping paper during cutting, the paper dust that falls off the cutting edge directly adheres to the cutting edge of the slitting disc; second, the paper dust that falls off the tipping paper falls into the slitting ring groove of the lower linkage roller. When there is a lot of paper dust in the slitting ring groove of the linkage roller, the cutting edge of the slitting disc extending into the slitting ring groove will be contaminated with paper dust.

[0005] During actual slitting, most of the paper scraps and powder generated at the cutting edge of the tipping paper fall into the slitting groove of the linkage roller. Some of the paper scraps and powder in the slitting groove will fall off naturally as the linkage roller rotates. However, if the paper scraps and powder remaining in the slitting groove are not discharged in time, they will accumulate more and more, causing the bottom edge of the slitting disc to be directly contaminated with paper scraps and powder. These paper scraps and powders will reach the tipping paper cutting edge position as the slitting disc rotates, affecting the slitting and cleaning winding effect of the tipping paper.

[0006] Current methods for cleaning the rollers involve installing a brush next to the roller and continuously cleaning it. However, this method has several problems: if the brush bristles are in close contact with the roller, it increases the load on the roller's rotation, affecting the paper's conductivity and increasing energy consumption. Furthermore, the brush bristles accumulate paper dust, requiring frequent cleaning to maintain effective cleaning. Conversely, if the brush bristles are not in close contact with the roller, many stubborn paper dust particles remain and cannot be removed.

[0007] In summary, how to reduce the amount of paper dust remaining on the linkage roller while ensuring the slitting and transmission efficiency of tipping paper, and how to prevent the cutting edge of the slitting disc from being contaminated with the paper dust remaining on the linkage roller, has become a problem that needs to be solved in tipping paper slitting. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to provide an integrated device and method for rewinding and slitting tipping paper, thereby ensuring the slitting effect of tipping paper while ensuring the slitting and conduction efficiency, and improving the cleanliness of the tipping paper after slitting and winding.

[0009] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0010] This invention provides an integrated rewinding and slitting device for cork paper, comprising the following components:

[0011] The slitting assembly is equipped with a guide frame, multiple slitting blades movably mounted on the guide frame, and an auxiliary drive motor located at one end of the guide frame that drives the multiple slitting blades to rotate.

[0012] The roller assembly is located below the slitting assembly. The roller assembly includes two fixed frames and a linkage roller rotatably mounted between the two fixed frames. The linkage roller has multiple slitting annular grooves on its circumferential side. Each slitting annular groove is independently aligned with a slitting cutter disc, and the lowest point of each slitting cutter disc extends into the top side area of ​​the slitting annular groove.

[0013] The system comprises an upstream detection component and a downstream detection component. The upstream detection component is located on one side of the roller assembly, and the downstream detection component is located on the other side. Both the upstream and downstream detection components are equipped with a horizontal frame positioned in the lower half of the linkage roller. The horizontal frame is equipped with a photoelectric probe facing the bottom of the slitting groove. The upstream and downstream detection components are also equipped with positioning angle plates fixedly mounted on a fixed frame. The two ends of the horizontal frame are fixedly connected to the positioning angle plates. The photoelectric probe's detection direction is parallel to the tangent direction of the slitting groove, and there is a gap between the photoelectric probe's detection direction and the inner annular surface of the slitting groove. The upper part of the horizontal frame has an upward slope, with the end of the upward slope closer to the linkage roller higher than the end farther from the linkage roller.

[0014] The negative pressure suction assembly is located between the upstream detection assembly and the downstream detection assembly. It is situated below the linkage roller and is equipped with a negative pressure main pipe and multiple negative pressure branch pipes connected to the negative pressure main pipe. Each negative pressure branch pipe is equipped with a negative pressure suction port facing the lowest point of the cutting ring groove, and each negative pressure branch pipe is equipped with an electrically controlled valve.

[0015] The linkage cleaning component is located between the downstream detection component and the slitting disc. It includes a stroke control cylinder containing an electromagnetic module, a push plate, and front and rear limit rings to restrict the push plate's range of motion. A magnetic block is mounted on the side of the push plate facing the electromagnetic module, and a connecting rod extending from the stroke control cylinder is fixedly connected to the side of the push plate facing away from the electromagnetic module. The stroke control cylinder is equipped with a tension spring sleeved on the connecting rod. A brush wheel is mounted on the outer end of the connecting rod, with hard bristles on its ring side that mate with the slitting ring groove. The tension spring is located between the front limit ring and the end plate of the stroke control cylinder. When the electromagnetic module is energized, the polarity of the magnetism is opposite to that of the magnetic block facing the electromagnetic module. When the electromagnetic module is de-energized, the maximum length of the hard bristles extending into the slitting ring groove is the same as the groove depth.

[0016] As a preferred embodiment of the device of the present invention, there is a gap of 1 to 3 mm between the lowest end of the slitting disc and the inner ring surface of the slitting groove.

[0017] As a preferred technical solution of the device of the present invention: a horizontal screw is fixedly provided at both ends of the horizontal frame, a horizontal protrusion is provided on the positioning corner plate, the horizontal protrusion is provided with a horizontal through hole, the horizontal screw passes through the horizontal through hole and is installed with a reinforcing knob.

[0018] As a preferred technical solution of the device of the present invention: the positioning angle plate is provided with a fixed side plate, the fixed side plate is provided with a fixed mounting hole, the fixing frame is provided with a through hole, and a bolt and nut mating structure is installed at the fixed mounting hole and the through hole of the fixing frame.

[0019] As a preferred technical solution of the device of the present invention: the gap between the linear direction detected by the photoelectric probe and the inner annular surface of the slitting groove is 1 to 3 mm.

[0020] As a preferred embodiment of the device of the present invention: let the distance between the front limiting ring and the rear limiting ring be La, and let the length of the hard bristles of the brush wheel be Lc. When the electromagnetic module is de-energized, let the length of the hard bristles extending into the cutting ring groove be Le, then Lc - Le > La.

[0021] This invention provides a driving and control method for an integrated rewinding and slitting device for cork paper, comprising the following:

[0022] S1. The slitting disc and the linkage roller come into contact with the tipping paper. The tipping paper is slit by the slitting disc, and the paper scraps and powder that fall off the tipping paper fall into the slitting ring groove.

[0023] S2. The linkage roller drives the paper scraps and powder in the slitting groove to rotate. During the rotation of the paper scraps and powder in the slitting groove, some of the paper scraps and powder fall off naturally, and some of the paper scraps and powder rotate with the slitting groove to the lower part of the slitting groove.

[0024] S3. The photoelectric probe of the upstream detection component performs real-time photoelectric detection:

[0025] When the photoelectric probe of the upstream detection component detects an unobstructed signal, the negative pressure branch pipe directly below the same cutting ring groove position will not have a negative pressure suction action.

[0026] When the photoelectric probe of the upstream detection component detects an obstruction signal, the negative pressure branch pipe directly below the same cutting ring groove position performs a negative pressure suction action.

[0027] S4. The photoelectric probe of the downstream detection component performs real-time photoelectric detection:

[0028] When the photoelectric probe of the downstream detection component detects an unobstructed signal, the electromagnetic module of the stroke control cylinder at the same slitting groove position is de-energized and does not operate, and the hard bristles of the brush wheel do not make extrusion contact with the inner ring surface of the slitting groove of the linkage roller.

[0029] When the photoelectric probe of the downstream detection component detects an obstruction signal, the electromagnetic module of the stroke control cylinder at the same cutting ring groove position is energized. The electromagnetic module pushes the magnetic block, push plate, and connecting rod to move towards the linkage roller, and the hard bristles of the brush wheel make extrusion contact with the inner ring surface of the cutting ring groove of the linkage roller.

[0030] Compared with existing technologies, the beneficial effects of this invention are:

[0031] This invention utilizes multiple independent negative pressure airflow intake structures configured on the bottom side of the linkage roller. An upstream detection component is positioned upstream of the negative pressure airflow intake structure to detect the tangential thickness accumulation of paper scraps that have not naturally detached from the slitting groove. When the amount of paper scraps remaining in the slitting groove is relatively thick, the corresponding negative pressure airflow intake structure performs a negative pressure intake operation at the bottom of the linkage roller, sucking the paper scraps out of the slitting groove. A downstream detection component is positioned downstream of the negative pressure airflow intake structure to detect the thicker paper scraps that have not yet been sucked out by the negative pressure airflow. A linkage cleaning component controls hard bristles to forcibly scrape away the thicker paper scraps remaining in the slitting groove. This reduces the amount of paper scraps remaining on the linkage roller while ensuring the slitting and transmission efficiency of the tipped paper. It also prevents the cutting edge of the slitting disc from being contaminated with the paper scraps remaining on the linkage roller, ensuring the slitting effect of the tipped paper and improving the cleanliness of the wound tipped paper after slitting.

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0041] Example 1: This invention designs an integrated rewinding and slitting device for tipping paper, mainly comprising a slitting component 1, a roller component 2, an upstream detection component 3a, a negative pressure suction component 4, a downstream detection component 3c, and a linkage cleaning component 5. The main structures that cooperate with each other are as follows:

[0042] Please see Figure 1 , Figure 2 , Figure 3The slitting assembly 1 is equipped with a guide frame 101, on which multiple rotating slitting discs 102 are mounted. An auxiliary drive motor 103 is mounted on one side of the guide frame 101, which drives the multiple slitting discs 102 to rotate.

[0043] The roller assembly 2 is located below the slitting assembly 1. The roller assembly 2 includes two fixed frames 201 and a linkage roller 202 rotatably mounted between the two fixed frames 201. The linkage roller 202 has multiple slitting annular grooves 2021 on its circumferential side. Each slitting annular groove 2021 is independently aligned with a slitting blade disc 102. Figure 2 , Figure 3 The lowest end of the slitting disc 102 extends into the top side area of ​​the slitting ring groove 2021, and there is a gap of 1 to 3 mm between the lowest end of the slitting disc 102 and the inner ring surface 2022 of the slitting ring groove 2021.

[0044] Please see Figure 2 , Figure 3 The upstream detection component 3a is located on one side of the roller assembly 2, and the downstream detection component 3c is located on the other side of the roller assembly 2. Both the upstream detection component 3a and the downstream detection component 3c are equipped with a transverse frame 301. The horizontal position of the transverse frame 301 is located in the lower half of the linkage roller 202. The transverse frame 301 is equipped with a photoelectric probe 3011. The photoelectric probe 3011 is directed towards the bottom area of ​​the cutting ring groove 2021.

[0045] The upper part of the transverse frame 301 is provided with an upper inclined surface 3013. The end of the upper inclined surface 3013 near the linkage roller is higher than the end away from the linkage roller 202. This allows paper scraps and powder that fall naturally from above to fall onto the upper inclined surface 3013 and be discharged directly outward, without falling onto the photoelectric probe 3011 and interfering with the detection.

[0046] The direction of the line detected by the photoelectric probe 3011 is parallel to the tangential direction of the slit ring groove 2021, and there is a gap between the direction of the line detected by the photoelectric probe 3011 and the inner ring surface 2022 of the slit ring groove 2021.

[0047] The gap between the linear direction detected by the photoelectric probe 3011 and the inner ring surface 2022 of the slitting groove 2021 is 1-3mm. This size needs to match the gap between the lowest end of the slitting disc and the bottom surface of the slitting groove. It's not necessary to forcibly clean the groove just because there is paper dust or powder inside; as long as the paper dust or powder does not directly contact the slitting disc and is not carried along by the disc, it's sufficient. The linear directions detected by the photoelectric probes 3011 of both the upstream detection component 3a and the downstream detection component 3c do not intersect with the inner ring surface 2022 of the slitting groove 2021, leaving a certain gap to allow for sufficient paper dust and powder to be absorbed. This reduces the need for constant cleaning, decreasing the operating frequency and workload of the linkage roller 202 and the cleaning equipment. Figure 2 , Figure 3 The inner ring surface of the slitting groove 2021 is the position of the dotted circle of the slitting groove 2021.

[0048] Please see Figure 1 , Figure 4 The upstream detection component 3a and the downstream detection component 3c are also equipped with positioning angle plates 302 fixedly installed on the fixed frame 201, and the two ends of the transverse frame 301 are fixedly connected to the positioning angle plates 302.

[0049] Please see Figure 1 , Figure 2 , Figure 3 The negative pressure suction component 4 is located between the upstream detection component 3a and the downstream detection component 3c. The negative pressure suction component 4 is located below the linkage roller 202. The negative pressure suction component 4 is equipped with a negative pressure main pipe 401. The negative pressure main pipe 401 is provided with multiple negative pressure branch pipes 402. The negative pressure suction port 4021 of the negative pressure branch pipe 402 faces the lowest point of the cutting ring groove 2021. Each negative pressure branch pipe 402 is equipped with an electric control valve 403. The electric control valve 403 controls the negative pressure airflow of the negative pressure branch pipe 402 at its respective position.

[0050] Please see Figure 2 , Figure 3 The linkage cleaning component 5 is located between the downstream detection component 3c and the slitting disc 102. The linkage cleaning component 5 includes a stroke control cylinder 501, which contains an electromagnetic module 502, a pusher plate 503, a front limit ring 507, and a rear limit ring 508. The front limit ring 507 and the rear limit ring 508 limit the range of motion of the pusher plate 503. The front limit ring 507 is closer to the linkage roller 202, and the rear limit ring 508 is farther away from the linkage roller 202. A magnetic block 509 is installed on one side of the pusher plate, facing the electromagnetic module 502. The magnetic polarity of the electromagnetic module 502 when it is energized is opposite to the polarity of the side of the magnetic block 509 facing the electromagnetic module 502. A connecting rod 504 is fixedly connected to the other side of the push plate 503. The connecting rod 504 faces away from the electromagnetic module 502. The connecting rod 504 extends outward from the stroke control cylinder 501. The stroke control cylinder 501 is equipped with a tension spring 510, which is sleeved on the connecting rod 504. The tension spring 510 is located between the front limit ring 507 and the side end plate of the stroke control cylinder 501. A brush wheel 505 is arranged on the outer end of the connecting rod 504. The brush wheel 505 has hard bristles 506 on its circumferential side, which cooperate with the cutting ring groove 2021.

[0051] The distance between the front limiting ring 507 and the rear limiting ring 508 is La, the length of the hard bristles 506 of the brush wheel 505 is Lc, and the length of the hard bristles 506 extending into the cutting ring groove 2021 is Le.

[0052] When the electromagnetic module 502 is de-energized, the maximum length of the rigid bristles 506 extending into the slitting ring groove 2021 is the same as the groove depth of the slitting ring groove 2021, that is, Le=La.

[0053] When the electromagnetic module 502 is de-energized: Lc-Le>La, this is easy to understand. In fact, when the hard bristles 506 are pushed towards the cutting ring groove 2021, the brush wheel 505 will not come into contact with the linkage roller 202.

[0054] Please see Figure 4 , Figure 5 , Figure 6 , Figure 7 The positioning angle plate 302 is provided with a fixed side plate 3023, the fixed side plate 3023 is provided with a fixed mounting hole 3024, the fixing bracket 201 is provided with a through hole, and a bolt and nut mating structure is installed at the fixed mounting hole 3024 and the through hole of the fixing bracket 201.

[0055] The horizontal screw 3012 is located at both ends of the horizontal frame 301. The positioning angle plate 302 is provided with a horizontal protrusion 3021. The horizontal protrusion 3021 has a horizontal through hole 3022. The horizontal screw 3012 passes through the horizontal through hole 3022 and is fitted with a reinforcing knob 303. Figure 1 , Figure 2 , Figure 3 When installing the upstream detection component 3a and the downstream detection component 3c, do not tighten the reinforcing knob 303 first. After the detection direction of the photoelectric probe is adjusted, tighten the reinforcing knob 303.

[0056] Example 2: This invention relates to a drive and control method for an integrated rewinding and slitting device for cork paper, comprising the following:

[0057] First, the slitting disc 102 and the linkage roller 202 come into contact with the tipping paper. The tipping paper is slit by the slitting disc 102, and the paper scraps and powder that fall off the tipping paper by the slitting disc 102 fall into the slitting ring groove 2021.

[0058] Then, the linkage roller 202 drives the paper scraps and powder in the slitting ring groove 2021 to rotate. During the rotation of the paper scraps and powder in the slitting ring groove 2021, some of the paper scraps and powder fall off naturally, and some of the paper scraps and powder rotate with the slitting ring groove 2021 to the lower part of the slitting ring groove 2021.

[0059] Then, the photoelectric probe 3011 of the upstream detection component 3a performs real-time photoelectric detection:

[0060] Scenario 1: When the photoelectric probe 3011 of the upstream detection component 3a detects an unobstructed signal, the negative pressure branch pipe 402 directly below the same cutting ring groove 2021 position does not have a negative pressure suction action, that is, the electric control valve 403 at this position can be closed.

[0061] Scenario 2: When the photoelectric probe 3011 of the upstream detection component 3a detects the obstruction signal, the negative pressure branch pipe 402 directly below the same cutting ring groove 2021 performs a negative pressure suction action, that is, the electric control valve 403 at this position can be opened.

[0062] Then, the downstream detection component 3C's photoelectric probe 3011 performs real-time photoelectric detection:

[0063] Scenario 1: When the photoelectric probe 3011 of the downstream detection component 3c detects an unobstructed signal, the electromagnetic module 502 of the stroke control cylinder 501 at the same position of the slitting ring groove 2021 is de-energized and does not operate. The hard bristles 506 of the brush wheel 505 do not make extrusion contact with the inner ring surface of the slitting ring groove 2021 of the linkage roller 202. When it is not necessary to forcibly scrape off the paper scraps and powder in the slitting ring groove 2021, the length of the hard bristles 506 extending into the slitting ring groove 2021 is small, so as not to increase the burden on the rotation of the linkage roller 202.

[0064] Scenario 2: When the photoelectric probe 3011 of the downstream detection component 3c detects an obstruction signal, the electromagnetic module 502 of the stroke control cylinder 501 at the same position of the slitting ring groove 2021 is energized. The electromagnetic module 502 pushes the magnetic block 509, the push plate 503, and the connecting rod 504 to move towards the linkage roller 202. The hard bristles 506 of the brush wheel 505 make squeezing contact with the inner ring surface of the slitting ring groove 2021 of the linkage roller 202. This forces the thicker paper dust that has not been sucked away by the negative pressure branch pipe 402 to be scraped off. In other words, the hard bristles 506 will only intervene when it is really necessary to use the hard bristles 506 for forced cleaning. This reduces the frequency of use of the hard bristles 506 and eliminates the need for frequent manual cleaning of the hard bristles 506.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
