Description

Technical Field

[0001] This invention belongs to the technical field of cigarette production equipment, specifically relating to a paper feeding guide device and guide method for a ZJ17 cigarette making machine. Background Technology

[0002] In cigarette production, tipping paper, also known as cork paper, is a crucial auxiliary material that bonds the filter to the cigarette pack. Its conveying and positioning accuracy directly determines the quality of the finished cigarette. The stability of the tipping paper's lateral position in the supply path directly affects the cutting position, the gluing position, and the appearance quality of the rolled cigarette. Tipping paper misalignment, where the tipping paper belt deviates from the preset lateral reference position during high-speed operation, leads to appearance defects such as inconsistent tipping paper length, misaligned gluing marks, rough edges, and curling edges.

[0003] The ZJ17 cigarette making machine is a widely used medium-speed cigarette making equipment in the tobacco industry. Its tipping paper supply path typically includes components such as a paper tray support, guide rollers, a doctor blade, a feed roller, a pressure roller shaft, and a guide block. The tipping paper tray is fixed on the paper tray support. The pressure roller shaft presses the tipping paper strip onto the feed roller. The friction between the feed roller, pressure roller shaft, and paper strip drives the tipping paper tray to rotate, supplying tipping paper in the running direction. The supplied tipping paper bypasses the guide block, which is a limiting part that is low in the middle and high on both sides, restricting the lateral movement of the paper strip. When the tipping paper deviates, the lateral position of the guide block is manually adjusted to correct the deviation.

[0004] While the aforementioned tipping paper supply path can constrain the lateral position of the paper tape to some extent, in actual production, the tipping paper tape is affected by factors such as tension fluctuations, mechanical vibrations, and friction fluctuations between the paper tape and the guide elements. This causes the paper tape and the guide block's side limit references to deform under pressure, deviating from the preset supply path and resulting in tape misalignment. This not only requires frequent manual intervention to correct the misalignment but also produces a large number of defective tipping papers of uneven length, increasing material consumption and, in severe cases, causing equipment downtime and reducing production efficiency.

[0005] Therefore, it is necessary to provide a paper feeding guide device and method for the ZJ17 winding and splicing machine that can stably guide the feeding paper in both the front-end supply path and the end path before entering the cutting wheel.

[0006] To address the aforementioned technical problems, this invention is proposed. Summary of the Invention

[0015] The rear baffle 25 and the front baffle 26 are respectively disposed on both sides of the guide groove 24 along the width direction of the splicing paper strip. They are used to limit the two sides of the splicing paper strip along the width direction when the splicing paper strip passes through the guide groove 24, so as to restrict the splicing paper strip from lateral displacement along its width direction. Among them, the splicing paper strip corresponding to the left guide block 13 is the spare splicing paper strip 16, and the splicing paper strip corresponding to the right guide block 18 is the currently supplied splicing paper strip 17.

[0017] The adjusting screw 27 is disposed on the side of the guide block bracket 22 and connected to the guide groove 24, and is used to adjust the lateral position of the guide groove 24 relative to the guide block bracket 22.

[0018] The end guide assembly includes an end guide block 20, which is disposed on the paper feed side of the paper cutting wheel 21 and is used to laterally limit the paper tape before it enters the paper cutting wheel 21.

[0019] The end guide block 20 includes a cylindrical shaft 200 and limiting baffles 201 disposed at both ends of the cylindrical shaft 200, and an end limiting channel for the paper tape to pass through is formed between the limiting baffles 201.

[0020] Preferably, the left guide block 13 and the right guide block 18 are arranged symmetrically with respect to the two sides of the paper receiving device 15.

[0021] Preferably, the distance between the limiting baffles 201 at both ends of the cylindrical shaft 200 is equal to the width of the receiving paper.

[0022] Preferably, the number of suction holes 23 is 4 to 12, which are arranged laterally along the guide groove 24, and the diameter of the suction holes 23 is 0.8 mm to 3.0 mm.

[0023] Preferably, the distance between the front baffle 26 and the rear baffle 25 is equal to the width of the splicing paper.

[0024] Preferably, the adjusting screw 27 is arranged along the width direction of the paper tape being dispensed, and the adjusting screw 27 is connected to the guide groove 24, for adjusting the position of the guide groove 24 relative to the guide block bracket 22 along the width direction of the paper tape being dispensed when rotated.

[0025] Preferably, both the guide groove 24 and the end guide block 20 are detachable and replaceable components; the guide groove 24 is provided with various specifications, and different specifications of the guide groove 24 correspond to different distances between the front baffle 26 and the rear baffle 25; the end guide block 20 is provided with various specifications, and different specifications of the end guide block 20 correspond to different distances between the two limiting baffles 201; for the same width of the splicing paper tape, the left guide block 13 and the right guide block 18 are configured with the same specification of guide groove 24, and the distance between the front baffle 26 and the rear baffle 25, as well as the distance between the two limiting baffles 201, are configured to allow the splicing paper tape to pass along the length direction and restrict the splicing paper tape from lateral displacement along the width direction.

[0026] In this invention, the spare splice paper tape 16 refers to the splice paper tape drawn from the spare paper tray and used to continue feeding paper when the currently supplied splice paper tape 17 is exhausted or nearly exhausted. The currently supplied splice paper tape 17 refers to the splice paper tape drawn from the currently supplied paper tray and continuously fed towards the paper cutting wheel during the operation of the winding and splicing machine.

[0027] Another aspect of the present invention provides a paper feeding guide method for a ZJ17 winding and splicing machine, employing the aforementioned paper feeding guide device for the ZJ17 winding and splicing machine, the method comprising the following steps:

[0028] S1. The spare splicing paper tape 16 is introduced into the left guide block 13 along the conveying path of the spare splicing paper tape 16 of the ZJ17 winding machine, and the spare splicing paper tape 16 is made to fit into the guide groove 24 of the left guide block 13.

[0029] S2. The current supply paper tape 17 is introduced into the right guide block 18 along the conveying path of the current supply paper tape 17 of the ZJ17 winding machine, and the current supply paper tape 17 is made to fit the guide groove 24 of the right guide block 18.

[0030] S3. Suction is provided to the partially enclosed cavity formed between the guide groove 24 and the guide block support 22 through the suction pipe interface 28, so that the suction acts on the splicing paper tape passing through the guide groove 24 through the suction hole 23 on the guide groove 24, so as to adsorb the splicing paper tape onto the guide groove 24.

[0031] S4. During the process of the splicing paper strip passing through the guide groove 24, the rear baffle 25 and the front baffle 26, which are respectively provided on both sides of the guide groove 24 along the width direction of the splicing paper strip, limit the two sides of the splicing paper strip along the width direction, so that the splicing paper strip can pass through the guide groove 24 along its length direction and restrict the splicing paper strip from lateral displacement along its width direction.

[0032] S5. When the paper tape passing through the left guide block 13 or the right guide block 18 shifts laterally relative to the predetermined conveying position, the adjusting screw 27 on the corresponding guide block is rotated to drive the corresponding guide groove 24 to move relative to the guide block bracket 22 along the width direction of the paper tape, so as to adjust the lateral position of the paper tape on the corresponding conveying path.

[0033] S6. The spare splicing paper tape 16 and the currently supplied splicing paper tape 17 are spliced ​​by the paper splicing device 15, so that the spliced ​​splicing paper tape is conveyed along the splicing paper tape conveying path toward the paper cutting wheel 21.

[0034] S7. After the spliced ​​paper tape passes through the paper roller 19, it enters the end guide block 20, and the spliced ​​paper tape passes through the end limiting channel formed between the two limiting baffles 201 of the end guide block 20. The two limiting baffles 201 laterally limit the spliced ​​paper tape before it enters the paper cutting wheel 21.

[0035] S8. The paper tape after being laterally limited by the end guide block 20 is conveyed to the paper cutting wheel 21, and the paper tape is cut by the paper cutting wheel 21.

[0036] Preferably, before step S1, guide grooves 24 and end guide blocks 20 that are compatible with the width specification of the splicing paper tape are selected respectively, and guide grooves 24 of the same width specification are installed on the left guide block 13 and the right guide block 18 respectively, so that the left guide block 13 and the right guide block 18 form lateral limits with the same width reference for the spare splicing paper tape 16 and the currently supplied splicing paper tape 17 respectively; at the same time, end guide blocks 20 of the corresponding width specification are installed on the paper feed side of the paper cutting roller 21, so that the end guide blocks 20 form end lateral limits for the splicing paper tape before entering the paper cutting roller 21 that match the left guide block 13 and the right guide block 18.

[0037] Preferably, in step S5, when adjusting the lateral position of the paper tape, the suction hole 23 maintains the adsorption effect of the paper tape, and the adjusting screw 27 on the corresponding guide block is rotated to drive the rear baffle 25 and front baffle 26 on both sides of the corresponding guide groove to move synchronously along the width direction of the paper tape. During the synchronous movement, the suction hole 23 keeps the paper tape attached to the guide groove 24, and the rear baffle 25 and front baffle 26 limit the two sides of the paper tape to correct the lateral offset of the paper tape relative to the predetermined conveying position.

[0038] The beneficial effects of this invention are:

[0039] Compared with the prior art, the present invention has at least the following beneficial effects:

[0040] 1. This invention, by setting a front-end dual-path guide assembly in the tipping paper supply path of the ZJ17 splicing machine, allows the left and right guide blocks to be respectively positioned on the conveying paths of the spare tipping paper tape and the currently supplied tipping paper tape. This enables pre-guiding and lateral limiting of the two tipping paper tapes at the front end of the splicing device. Compared with the method of limiting solely by the original guide roller or a single guide block, this invention can constrain the lateral position of the tipping paper tape before it enters the splicing position, reducing the risk of lateral deviation of the spare and currently supplied tipping paper tapes due to tension fluctuations, equipment vibration, or changes in friction before splicing, thereby improving the stability of the tipping paper splicing process.

[0041] 2. Both the left and right guide blocks of this invention are equipped with guide grooves, suction holes, suction pipe interfaces, front baffles, and rear baffles. The suction pipe interface can provide suction to the cavity formed between the guide groove and the guide block support, and the paper tape being fed into the guide groove is adsorbed through the suction holes. Simultaneously, the front and rear baffles can limit the two side edges of the paper tape in the width direction. Therefore, this invention forms a composite guiding method of "suction adsorption positioning + mechanical limiting on both sides," which can reduce the shaking, warping, and drifting of the paper tape during high-speed conveying, and avoid deformation and swaying caused by simple squeezing between the paper tape and the limiting components, thus helping to maintain the stable operation of the paper tape along the predetermined conveying reference.

[0042] 3. This invention allows for adjustment of the lateral position of the guide groove relative to the guide block support by setting an adjusting screw connected to the guide groove on the side of the guide block support. When the paper tape shifts laterally relative to the predetermined conveying position, the operator can correct the position of the guide groove by rotating the adjusting screw, thereby simultaneously adjusting the suction position of the suction hole on the paper tape and the limiting positions of the front and rear baffles on both sides of the paper tape. This structure enables rapid correction without significant disassembly and modification of the original paper feeding system, reducing frequent downtime for adjustments and repeated manual intervention, and improving the continuous operation capability and ease of debugging of the equipment.

[0043] 4. This invention also includes an end guide block on the paper feed side of the paper cutting wheel. The end guide block forms an end limiting channel through a cylindrical shaft and end limiting baffles, ensuring that the feed paper strip is again laterally limited before entering the paper cutting wheel. The front-end dual-path guide assembly works in conjunction with the end guide assembly to form multi-level guiding and limiting at the front end of the paper receiving device and the paper feed side of the paper cutting wheel, preventing the paper strip from deviating from the predetermined position again during long-distance transport. This improves the accuracy of the paper cutting position and subsequent winding position, reduces quality defects such as uneven feed paper length, glue imprint deviation, rough edges, and curling edges, lowers the defect rate and auxiliary material waste, and improves the appearance quality of cigarette products and equipment operating efficiency.

[0062] The guide groove 24 is disposed on the guide block support 22, and a partially closed cavity is formed between the guide groove 24 and the guide block support 22;

[0063] The rear baffle 25 and the front baffle 26 are respectively disposed on both sides of the guide groove 24 along the width direction of the splicing paper strip. They are used to limit the two sides of the splicing paper strip along the width direction when the splicing paper strip passes through the guide groove 24, so as to restrict the splicing paper strip from lateral displacement along its width direction. Among them, the splicing paper strip corresponding to the left guide block 13 is the spare splicing paper strip 16, and the splicing paper strip corresponding to the right guide block 18 is the currently supplied splicing paper strip 17.

[0064] The guide groove 24 is provided with a suction hole 23 that communicates with the partially enclosed cavity. The suction pipe interface 28 is provided on the side of the guide block bracket 22 and forms a suction channel with the guide groove 24, the front baffle 26 and the rear baffle 25.

[0065] The adjusting screw 27 is disposed on the side of the guide block bracket 22 and connected to the guide groove 24, and is used to adjust the lateral position of the guide groove 24 relative to the guide block bracket 22.

[0066] The end guide assembly includes an end guide block 20, which is disposed on the paper feed side of the paper cutting wheel 21 and is used to laterally limit the paper tape before it enters the paper cutting wheel 21.

[0067] The end guide block 20 includes a cylindrical shaft 200 and limiting baffles 201 disposed at both ends of the cylindrical shaft 200, and an end limiting channel for the paper tape to pass through is formed between the limiting baffles 201.

[0068] The left guide block 13 and the right guide block 18 are arranged symmetrically with respect to the two sides of the paper receiving device 15.

[0069] The distance between the limiting baffles 201 located at both ends of the cylindrical shaft 200 is equal to the width of the receiving paper.

[0070] There are 6 suction holes 23, which are arranged laterally along the guide groove 24, and the diameter of each suction hole 23 is 2.0 mm.

[0071] The distance between the front baffle 26 and the rear baffle 25 is equal to the width of the paper being dispensed.

[0072] The adjusting screw 27 is arranged along the width direction of the paper tape being dispensed, and the adjusting screw 27 is connected to the guide groove 24, which is used to adjust the position of the guide groove 24 relative to the guide block bracket 22 along the width direction of the paper tape being dispensed when it is rotated.

[0073] Both the guide groove 24 and the end guide block 20 are detachable and replaceable components. The guide groove 24 is provided with various specifications, and different specifications of the guide groove 24 correspond to different distances between the front baffle 26 and the rear baffle 25. The end guide block 20 is provided with various specifications, and different specifications of the end guide block 20 correspond to different distances between the two limiting baffles 201. For the same width of the splicing paper tape, the left guide block 13 and the right guide block 18 are configured with the same specification of guide groove 24. The distance between the front baffle 26 and the rear baffle 25, as well as the distance between the two limiting baffles 201, are all configured to allow the splicing paper tape to pass along the length direction and restrict the splicing paper tape from lateral displacement along the width direction.

[0074] In this invention, the spare splice paper tape 16 refers to the splice paper tape drawn from the spare paper tray and used to continue feeding paper when the currently supplied splice paper tape 17 is exhausted or nearly exhausted. The currently supplied splice paper tape 17 refers to the splice paper tape drawn from the currently supplied paper tray and continuously fed towards the paper cutting wheel during the operation of the winding and splicing machine.

[0075] A paper feeding guide method for a ZJ17 winding and splicing machine, employing the aforementioned paper feeding guide device for the ZJ17 winding and splicing machine, includes the following steps:

[0076] S1. The spare splicing paper tape 16 is introduced into the left guide block 13 along the conveying path of the spare splicing paper tape 16 of the ZJ17 winding machine, and the spare splicing paper tape 16 is made to fit into the guide groove 24 of the left guide block 13.

[0077] S2. The current supply paper tape 17 is introduced into the right guide block 18 along the conveying path of the current supply paper tape 17 of the ZJ17 winding machine, and the current supply paper tape 17 is made to fit the guide groove 24 of the right guide block 18.

[0078] S3. Suction is provided to the partially enclosed cavity formed between the guide groove 24 and the guide block support 22 through the suction pipe interface 28, so that the suction acts on the splicing paper tape passing through the guide groove 24 through the suction hole 23 on the guide groove 24, so as to adsorb the splicing paper tape onto the guide groove 24.

[0079] S4. During the process of the splicing paper strip passing through the guide groove 24, the rear baffle 25 and the front baffle 26, which are respectively provided on both sides of the guide groove 24 along the width direction of the splicing paper strip, limit the two sides of the splicing paper strip along the width direction, so that the splicing paper strip can pass through the guide groove 24 along its length direction and restrict the splicing paper strip from lateral displacement along its width direction.

[0080] S5. When the paper tape passing through the left guide block 13 or the right guide block 18 shifts laterally relative to the predetermined conveying position, the adjusting screw 27 on the corresponding guide block is rotated to drive the corresponding guide groove 24 to move relative to the guide block bracket 22 along the width direction of the paper tape, so as to adjust the lateral position of the paper tape on the corresponding conveying path.

[0081] S6. The spare splicing paper tape 16 and the currently supplied splicing paper tape 17 are spliced ​​by the paper splicing device 15, so that the spliced ​​splicing paper tape is conveyed along the splicing paper tape conveying path toward the paper cutting wheel 21.

[0082] S7. After the spliced ​​paper tape passes through the paper roller 19, it enters the end guide block 20, and the spliced ​​paper tape passes through the end limiting channel formed between the two limiting baffles 201 of the end guide block 20. The two limiting baffles 201 laterally limit the spliced ​​paper tape before it enters the paper cutting wheel 21.

[0083] S8. The paper tape after being laterally limited by the end guide block 20 is conveyed to the paper cutting wheel 21, and the paper tape is cut by the paper cutting wheel 21.

[0084] Before step S1, guide grooves 24 and end guide blocks 20 that are compatible with the width specification of the splicing paper tape are selected according to the width specification. Guide grooves 24 of the same width specification are installed on the left guide block 13 and the right guide block 18 respectively, so that the left guide block 13 and the right guide block 18 form lateral limits with the same width reference for the spare splicing paper tape 16 and the currently supplied splicing paper tape 17 respectively. At the same time, end guide blocks 20 of the corresponding width specification are installed on the paper feed side of the paper cutting roller 21, so that the end guide blocks 20 form end lateral limits for the splicing paper tape before entering the paper cutting roller 21 that match the left guide block 13 and the right guide block 18.

[0085] In step S5, when adjusting the lateral position of the paper tape, the suction hole 23 maintains the adsorption effect on the paper tape. The adjusting screw 27 on the corresponding guide block is rotated so that the corresponding guide groove 24 drives the rear baffle 25 and the front baffle 26 on both sides to move synchronously along the width direction of the paper tape. During the synchronous movement, the suction hole 23 keeps the paper tape in contact with the guide groove 24, and the rear baffle 25 and the front baffle 26 limit the two sides of the paper tape to correct the lateral offset of the paper tape relative to the predetermined conveying position.

[0086] The working principle of this invention is as follows: During the operation of the ZJ17 paper feeding machine, the spare paper feeding tape 16 and the currently supplied paper feeding tape 17 run along their respective conveying paths. The spare paper feeding tape 16 passes through the left guide block 13, and the currently supplied paper feeding tape 17 passes through the right guide block 18. Since the left guide block 13 and the right guide block 18 have the same structural principle, they respectively guide the front end of the paper feeding tape on the corresponding conveying path and limit its lateral movement.

[0087] Taking the right guide block 18 as an example, after the suction pipe interface 28 is connected to the original suction system of the ZJ17 winding and splicing machine, the suction enters the partially enclosed cavity formed between the guide groove 24 and the guide block support 22, and acts on the splicing paper tape passing through the guide groove 24 via the suction holes 23 on the guide groove 24, so that the splicing paper tape is stably adsorbed and adheres to the surface of the guide groove 24. At the same time, the rear baffle 25 and the front baffle 26 set on both sides of the guide groove 24 respectively limit the two sides of the splicing paper tape in the width direction, so that the splicing paper tape can pass smoothly through the guide groove 24 in its length direction and restrict its lateral displacement in the width direction. Thus, the splicing paper tape is simultaneously subjected to the combined effects of suction adsorption positioning and mechanical limiting by the baffles on both sides during the front-end conveying stage, thereby improving the stability of the paper tape conveying position.

[0088] In actual production, when the feed paper tape shifts laterally relative to the predetermined conveying position due to tension fluctuations, equipment vibration, or changes in friction, the operator can rotate the adjusting screw 27 on the corresponding guide block according to the direction of tape deviation. The adjusting screw 27 drives the guide groove 24 to move relative to the guide block bracket 22 along the width direction of the feed paper tape, thereby changing the lateral position of the guide groove 24. This adjusts the suction position of the suction hole 23 on the tape and the limiting positions of the rear baffle 25 and the front baffle 26 on the two sides of the tape, thus correcting the lateral position of the feed paper tape. For example, when the feed paper tape shifts outward, the adjusting screw 27 can be rotated to move the guide groove 24 inward, so that the tape returns to the predetermined conveying reference position.

[0089] When the current supply of splicing paper tape 17 is exhausted or nearly exhausted, the splicing device 15 will continue to supply spare splicing paper tape 16 to the splicing paper tape conveying path. The spliced ​​splicing paper tape continues to be conveyed towards the cutting wheel 21 via the paper roller 19, and passes through the end guide block 20 before entering the cutting wheel 21. The end guide block 20 includes a cylindrical shaft 200 and limiting baffles 201 disposed at both ends of the cylindrical shaft 200. The splicing paper tape passes between the two limiting baffles 201 and contacts the cylindrical shaft 200. The two limiting baffles 201 provide lateral end limiting for the splicing paper tape, so that the splicing paper tape enters the cutting wheel 21 in a stable lateral position, thereby improving the accuracy of the cutting position.

[0090] When the equipment's production grade changes or the width specification of the splicing paper tape changes, the guide groove 24 and end guide block 20 can be replaced with those adapted to the corresponding splicing paper tape width specification. The left guide block 13 and right guide block 18 are equipped with guide grooves 24 of the same specification, and the end guide block 20 adopts the corresponding specification, ensuring that the front-end dual-path guide assembly and the end guide assembly form a continuous and stable multi-level guiding limit for the splicing paper tape under the same width reference. Through the above process, this invention can effectively reduce the risk of splicing paper tape deviation, reduce quality defects such as uneven splicing paper length, glue application position misalignment, burrs, and curling edges, and reduce the frequency of manual correction and downtime adjustment time.

[0091] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
