Description

Technical Field

[0001] The present invention belongs to the technical field of base paper winding for paper cup production, and in particular relates to a base paper laminating and winding device and a base paper laminating and winding method for paper cup production. Background Art

[0002] A paper cup is a paper container made by mechanically processing and gluing paper made from chemical wood pulp. To improve the leak-proofness of paper cups, a film is typically applied to the paper. This film not only prevents the cup from leaking but also helps form the cup during production.

[0003] The base paper needs to be rolled up after laminating, and the applicant has retrieved some existing technologies to achieve the rolling up of the base paper. For example, the patent publication number CN119284611B is a base paper laminating and rolling device and a base paper laminating and rolling method for paper cup production. Its main technical means is to install multiple winding shafts through a rotating bracket. When the coated base paper is rolled up on one of the winding shafts, the rotating bracket can drive the winding shaft to rotate in a circular motion, so that the other winding shaft equipped with a winding sleeve is moved to the winding station, and the winding shaft with the paper roll is moved to the outside of the frame. After that, the coated base paper is cut and the cut end is wound on the surface of the new winding sleeve to continue to roll up the coated base paper, so that the laminating equipment does not need to be stopped and waited synchronously when changing the roll, which is beneficial to improving the base paper laminating efficiency. After analysis by the applicant, the disadvantage of this technical solution is that: in the above solution, after a set of winding shafts have wound up the base paper, the base paper needs to be cut first, and then the base paper needs to be wound around the surface of a new winding sleeve. This process cannot achieve continuous winding and requires pausing the winding to achieve this. In this way, both the winding device and the laminating equipment need to be briefly stopped, thereby reducing the winding efficiency and the laminating efficiency. Summary of the Invention

[0004] The purpose of the present invention is to address the shortcomings of the existing technology and provide a base paper laminating and winding device and a base paper laminating and winding method for paper cup production, so as to solve the technical problem in the existing technology that the winding device and the laminating equipment still need to be briefly shut down when changing the winding sleeve, thereby reducing the winding efficiency and the laminating efficiency.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A base paper laminating and winding device comprises a bottom plate, two sets of brackets, two sets of turntables, and a positioning motor for driving the turntables to rotate. The device also comprises:

[0007] A rotating shaft, wherein the rotating disc is provided with a plurality of notches, and the two ends of the rotating shaft are respectively sleeved in the overlapping notches on the two rotating discs, and a baffle is provided on the outside of the notch, and the baffle abuts against the end of the rotating shaft, and a winding motor is installed on the bracket, and the output end of the winding motor is connected to the rotating shaft in a non-contact transmission manner, and the rotating shaft is covered with a winding sleeve;

The shaft of the rotating part of the pressure rod is fixedly connected to the pressure rod, and a through slot is provided on the rotating shaft, and the rack passes through the through slot.

[0015] As a preferred embodiment of the above technical solution, a pressure roller is installed on the bottom plate.

[0016] As a preferred embodiment of the above technical solution, a counterweight is fixed to the bottom of the mounting plate, and the counterweight is always vertically downward when the rotating shaft does not rotate.

[0017] As a preference of the above technical solution, a discharge plate is provided on the bottom plate. The discharge plate is located away from the pressure roller. Two guide plates are symmetrically arranged on the bottom plate. The guide plates are close to the pressure roller. The two guide plates are respectively close to two opposite groups of turntables. A rotating shaft with a new winding sleeve sleeved on the periphery is placed on the two guide plates. The highest point of the rotating shaft here is above the lowest point of the lowest notch of the turntable. After the turntable rotates, the notch drives the rotating shaft to move along the guide plate, so that the rotating shaft is sleeved on the innermost side of the notch.

[0018] As a preference of the above technical solution, a groove is provided on the surface of the winding sleeve. The pressing rod is located in the groove. A cutting knife is provided on one side of the pressing rod close to the discharge plate. The cutting knife inclines obliquely downward.

[0019] As a preference of the above technical solution, there are two groups of rotating shafts. The two groups of rotating shafts are respectively sleeved on both ends of the winding sleeve. Grooves are provided at the opposite ends of the two groups of rotating shafts. A movable rod is longitudinally and movably installed on the winding sleeve. The movable rod passes through the groove. The movable rod is located below the position where the two pressing rods abut against each other. A U-shaped rod is provided at the bottom of the movable rod.

One end of the U-shaped rod respectively passes through the connecting grooves provided in the grooves of the rotating shaft and on the inner wall of the winding sleeve, so that the rotating shaft and the winding sleeve are fixed together.

[0020] A winding method of a base paper laminating and winding device. The method is applied to the base paper laminating and winding device as described above. The method includes the following steps:

[0021] Step S1: First, sleeved a plurality of rotating shafts with winding sleeves sleeved on the periphery into the opposite notches on the two turntables, and then place a rotating shaft with a winding sleeve sleeved on the periphery on the two guide plates;

[0022] Step S2: Then place the break of the base paper on the surface of the uppermost winding sleeve. The pressing rod moves downward through the pressing mechanism to clamp the base paper, and then the rotating shaft and the winding sleeve rotate to wind the base paper through the winding motor;

[0023] Step S3: Before the uppermost winding sleeve winds up the base paper, control the pressing mechanism on the rotating shaft at the front end of the rotation of the uppermost winding sleeve to make the two pressing rods here rotate to a state perpendicular to the rotating shaft, and then make the turntable rotate through the position adjustment motor to make this group of rotating shafts rotate to the top, then make the pressing rod rotate to a state parallel to the rotating shaft, and then make the pressing rod move downward through the pressing mechanism to clamp the base paper, and at the same time cut the base paper through the cutting knife, and the rotating shaft rotates at the same time to make the winding sleeve wind the base paper, realizing continuous winding of the base paper;

[0024] Step S4: When the top winding sleeve completes winding and reaches above the discharge plate, the telescopic member here contracts the limit plate, and the restriction on the rotating shaft is released. The rotating shaft will roll along the notch to make the winding sleeve and the wound base paper roll off the discharge plate, thereby completing automatic unloading.

[0025] The beneficial effects of the present invention are:

[0026] 1. In the present invention, the pressing mechanism moves the pressing rod downward, thereby clamping the base paper and cutting the base paper at the same time. In this way, the rotating shaft will immediately reel in the base paper after rotation, thereby realizing continuous reeling of the base paper. This eliminates the need for the reeling device and the laminating equipment to stop briefly, thereby improving the reeling efficiency and the laminating efficiency.

[0027] 2. In the present invention, when the rotating shaft rotates to the uppermost position and the pressure rod moves downward, the cutter on the pressure rod will slowly approach the base paper and cut the base paper. In this way, the base paper is cut while the pressure rod clamps the base paper. Therefore, when the rotating shaft rotates to the uppermost position and the pressure rod moves downward to clamp the base paper, the winding sleeve can be immediately driven to wind up the base paper, thereby further realizing continuous winding of the base paper, further avoiding the short shutdown of the winding device and the laminating equipment at this time, and further improving the winding efficiency and the laminating efficiency.

[0028] 3. In the present invention, before the rotating shaft rotates to the highest point, the two pressure rods are moved toward the winding sleeve by the downward pressure mechanism on the rotating shaft, so that the base paper is passed around from under the pressure roller, so that the two pressure rods are pressed against the bottom of the base paper, thereby controlling the tension of the base paper. Since the overall diameter of the uppermost winding sleeve gradually increases when winding the base paper, the tension of the base paper will become greater and greater when the rotating shaft speed remains unchanged, which may cause the base paper to break due to excessive tension. At this time, the height of the two pressure rods cooperating with the pressure roller can be controlled to slowly move downward, thereby reducing the tension of the base paper, effectively preventing the base paper from breaking, and ensuring the integrity of the wound base paper.

[0029] 4. In the present invention, when the shaft rotates, the counterweight block swings outward due to centrifugal force, generating a torque opposite to the winding direction, which can balance the pulling force of the base paper, thereby maintaining a stable tension of the base paper, which helps to prevent the base paper from being too loose (causing wrinkles or deviations) or too tight (possibly causing breakage or deformation); at the same time, during the winding process, the counterweight block will automatically adjust the torque as the winding diameter changes, maintain the uniformity of the winding, avoid tension fluctuations caused by changes in the winding diameter, and effectively avoid wrinkles, deviations, breakage or deformation of the base paper during winding; in addition, the counterweight block increases the rotational inertia of the shaft, making the speed of the shaft change more slowly when starting or stopping, and combined with the non-contact transmission of the shaft and the winding motor, it can reduce mechanical shock and wear, thereby improving the life of the equipment.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0041] like Figures 1-6 As shown, a base paper laminating and winding device includes a base plate 1, two sets of brackets 2, two sets of turntables 3 and a positioning motor 11 for driving the turntables 3 to rotate. The device also includes:

[0042] The rotating shaft 4 and the turntable 3 are provided with a plurality of notches 31. The two ends of the rotating shaft 4 are respectively inserted into the overlapping notches 31 on the two turntables 3. A baffle 32 is provided on the outside of the notch 31. The baffle 32 abuts against the end of the rotating shaft 4. The bracket 2 is provided with a winding motor 12. The output end of the winding motor 12 is connected to the rotating shaft 4 in a non-contact transmission manner. The rotating shaft 4 is covered with a winding sleeve 5.

[0043] The limit assembly 6 is installed in the turntable 3. The number of limit assemblies 6 is the same as the number of notches 31. The limit assembly 6 includes a telescopic member 61. The output end of the telescopic member 61 is provided with a limit plate 62. The limit plate 62 is used to limit the shaft 4 from leaving the notch 31.

[0044] A pressing mechanism 7 is installed on the periphery of the rotating shaft 4 and is located on the outside of the winding sleeve 5;

[0045] The pressure rod 8 is connected to the pressing mechanism 7. The pressure rod 8 is driven by the pressing mechanism 7 to move downward and contact the surface of the winding sleeve 5 and clamp the base paper. The pressure rod 8 can also be rotated by the pressing mechanism 7.

[0046] Furthermore, the pressing mechanism 7 includes:

[0047] A mounting plate 71 is movably sleeved on the outer periphery of the rotating shaft 4. A locking member 713 is provided on the mounting plate 71 for fixing the mounting plate 71 and the rotating shaft 4;

[0048] The telescopic member 2 72 , a through hole 1 711 is provided on the mounting plate 71 , the telescopic member 2 72 is installed in the through hole 1 711 , the output end of the telescopic member 2 72 is provided with a connecting plate 73 , a connecting rod 77 is provided at the bottom of the connecting plate 73 , and the connecting rod 77 is connected to the pressure rod 8 .

[0049] The end of the pressure rod 8 away from the winding sleeve 5 is hinged with a fixed end 81, and the hinged part of the pressure rod 8 and the fixed end 81 is located between the mounting plate 71 and the winding sleeve 5. The connecting rod 77 is fixed on the fixed end 81. The mounting plate 71 is provided with a second through hole 712, and the fixed end 81 passes through the second through hole 712. A telescopic part 3 74 is installed at the bottom of the connecting plate 73, and a rack 75 is provided at the output end of the telescopic part 3 74. A gear 76 is installed on the shaft of the rotating part of the pressure rod 8, and the gear 76 and the rack 75 are engaged with each other. The shaft of the rotating part of the pressure rod 8 is fixedly connected to the pressure rod 8, and a through slot 41 is provided on the rotating shaft 4, and the rack 75 passes through the through slot 41.

[0050] A pressure roller 15 is installed on the bottom plate 1.

[0051] A counterweight 9 is fixed to the bottom of the mounting plate 71 , and the counterweight 9 is always vertically downward when the rotating shaft 4 does not rotate.

[0052] In one case of this embodiment, telescopic part 1 61, telescopic part 2 72 and telescopic part 3 74 can all be cylinders, or other components that can be telescopically driven; a magnetic coupling is formed between the rotating shaft 4 and the winding motor 12, thereby achieving non-contact transmission.

[0053] When this embodiment is actually used, the limit plate 62 is moved to limit the rotating shaft 4 through the telescopic member 1 61, and the coated base paper is wound around the outer periphery of the uppermost group of winding sleeves 5. The telescopic member 2 72 is extended, so that the connecting plate 73 drives the connecting rod 77 to move the pressure rod 8 downward, so that the pressure rod 8 clamps the base paper, and the rotating shaft 4 is rotated by the winding motor 12. The rotating shaft 4 and the winding sleeve 5 rewind the base paper. When the rewinding sleeve 5 rewinds a certain amount of base paper, the telescopic member 3 74 on the other group of rotating shafts 4 is first extended, so that the rack 75 drives the gear 76 to rotate, thereby rotating the pressure rod 8. The pressing rod 8 is rotated to a state perpendicular to the rotating shaft 4, and then the positioning motor 11 is used to rotate the turntable 3, so that the other set of rotating shafts 4 is rotated to the top. At this time, the pressing rod 8 is perpendicular to the rotating shaft 4, which will prevent the pressing rod 8 from being blocked by the base paper when moving. Then the pressing rod 8 is rotated to a state parallel to the rotating shaft 4, and then the pressing mechanism 7 is used to move the pressing rod 8 downward, thereby clamping the base paper and cutting the base paper at the same time. In this way, the rotating shaft 4 will immediately reel in the base paper after rotation, thereby realizing continuous reeling of the base paper, which does not require the reeling device and the laminating equipment to be temporarily stopped, thereby improving the reeling efficiency and the laminating efficiency.

[0054] Before the rotating shaft 4 rotates to the highest point, the two pressure rods 8 are moved toward the winding sleeve 5 by the downward pressure mechanism 7 on the rotating shaft 4, so that the base paper is passed around from under the pressure roller 15, so that the two pressure rods 8 are pressed against the bottom of the base paper, thereby controlling the tension of the base paper. Since the overall diameter of the uppermost winding sleeve 5 gradually increases when winding the base paper, the tension of the base paper will become greater and greater when the rotating speed of the rotating shaft 4 remains unchanged, which may cause the base paper to break due to excessive tension. At this time, the height of the two pressure rods 8 cooperating with the pressure roller 15 can be controlled to slowly move the pressure rods 8 downward, thereby reducing the tension of the base paper, effectively avoiding base paper breakage, and ensuring the integrity of the wound base paper.

[0055] The counterweight 9 can ensure that the pressure rod 8 is always located above the winding sleeve 5, thereby ensuring that the pressure rod 8 presses the base paper or the pressure rod 8 is against the bottom of the base paper; when the rotating shaft 4 rotates, the counterweight 9 swings outward due to centrifugal force, generating a torque opposite to the winding direction, which can balance the pulling force of the base paper, thereby maintaining a stable tension of the base paper, which helps to prevent the base paper from being too loose (causing wrinkles or deviations) or too tight (which may cause breakage or deformation); at the same time, during the winding process, the counterweight 9 will automatically adjust the torque as the winding diameter changes, maintain the uniformity of the winding, avoid tension fluctuations caused by changes in the winding diameter, and effectively avoid wrinkles, deviations, breakage or deformation of the base paper during winding; in addition, the counterweight 9 increases the rotational inertia of the rotating shaft 4, making the speed of the rotating shaft 4 change more smoothly when starting or stopping, and combined with the non-contact transmission of the rotating shaft 4 and the winding motor 12, it can reduce mechanical shock and wear, thereby improving the life of the equipment.

[0056] like Figure 1 and Figure 2 As shown, a discharge plate 13 is provided on the bottom plate 1, and the discharge plate 13 is located away from the pressure roller 15. Two guide plates 14 are also symmetrically provided on the bottom plate 1, and the guide plates 14 are close to the pressure roller 15. The two guide plates 14 are respectively close to the two opposite groups of turntables 3. The rotating shaft 4 with a new winding sleeve 5 on the outer periphery is placed on the two guide plates 14. The highest point of the rotating shaft 4 here is above the lowest point of the notch 31 at the bottom of the turntable 3. After the turntable 3 rotates, the rotating shaft 4 is driven to move along the guide plate 14 through the notch 31, so that the rotating shaft 4 is sleeved on the innermost side of the notch 31.

[0057] In one case of this embodiment, the discharge plate 13 is in an inclined state, and the upper part of the discharge plate 13 is in an arc shape; the bottom of the guide plate 14 is in an arc shape, and the other parts are in an elliptical arc shape.

[0058] When the present embodiment is actually used, after the top winding sleeve 5 has finished winding, the position adjusting motor 11 rotates the turntable 3, so that the winding sleeve 5 with the wound base paper is moved to the discharge plate 13. At this time, the telescopic member 161 contracts the limit plate 62, and the restriction on the rotating shaft 4 is released. The rotating shaft 4 will roll along the notch 31 and the discharge plate 13, thereby completing automatic unloading. This reduces the workload of the workers. When the winding sleeve 5 moves to the discharge plate 13, the discharge plate 13 can support the winding sleeve 5 with the wound base paper, which can effectively prevent the winding sleeve 5 and the rotating shaft 4 from bending and deformation due to the weight of the base paper.

[0059] When the coiling device is working, the worker places the rotating shaft 4 with the coiling sleeve 5 on the two guide plates 14, and ensures that there is always a rotating shaft 4 with the coiling sleeve 5 on the two guide plates 14. In this way, after one round of coiling is completed, the rotating shaft 4 and the coiling sleeve 5 can be automatically replaced, thus ensuring the continuity of the coiling work, improving the coiling efficiency, and cooperating with the automatic unloading of the coiling sleeve 5, which can effectively avoid the shutdown of the coiling device and the film laminating equipment, thereby improving the coiling efficiency and the film laminating efficiency.

[0060] As Figure 8 shown, a slot 54 is formed on the surface of the coiling sleeve 5, the pressure bar 8 is located in the slot 54, a cutter 82 is arranged on one side of the pressure bar 8 close to the discharge plate 13, and the cutter 82 inclines obliquely downward.

[0061] In one case of this embodiment, the total length of the two cutters 82 on the two pressure bars 8 is greater than the length of the coiling sleeve 5, that is, the width of the base paper.

[0062] In the actual application of this embodiment, when the rotating shaft 4 rotates to the top and the pressure bar 8 moves downward, the cutter 82 on the pressure bar 8 will slowly approach the base paper and cut the base paper. In this way, while the pressure bar 8 clamps the base paper, the base paper is cut off, so that when the rotating shaft 4 rotates to the top and the pressure bar 8 moves downward to clamp the base paper, it can immediately drive the coiling sleeve 5 to coil the base paper, thereby further realizing the continuous coiling of the base paper, further avoiding the short-term shutdown of the coiling device and the film laminating equipment at this time, and further improving the coiling efficiency and the film laminating efficiency.

[0063] As Figure 4 and Figure 7 shown, there are two groups of rotating shafts 4, and the two groups of rotating shafts 4 are respectively sleeved at both ends of the coiling sleeve 5. Grooves 42 are formed at one end of the two groups of rotating shafts 4 facing each other. A movable rod 51 is longitudinally and movably installed on the coiling sleeve 5. The movable rod 51 passes through the slot 54. The movable rod 51 is located below the position where the two pressure bars 8 abut against each other. A U-shaped rod 52 is arranged at the bottom of the movable rod 51. An elastic member 53 is connected between the U-shaped rod 52 and the inner wall of the coiling sleeve 5. The elastic member 53 is located outside the movable rod 51. Connecting grooves 10 are formed in the grooves 42 of the rotating shaft 4 and on the inner wall of the coiling sleeve 5. One end of the U-shaped rod 52 respectively passes through the connecting grooves 10 formed in the grooves 42 of the rotating shaft 4 and on the inner wall of the coiling sleeve 5, so as to fix the rotating shaft 4 and the coiling sleeve 5 together.

[0064] In one case of this embodiment, the elastic member 53 can be a spring or other components that can elastically expand and contract.

[0065] In actual application of this embodiment, when the pressure rod 8 moves down and is sleeved in the embedding groove 54, the pressure rod 8 will press the movable rod 51 downward, so that the movable rod 51 drives the C-shaped rod 52 to move downward, so that the two ends of the C-shaped rod 52 pass through the two grooves 42 and the connecting groove 10 opened on the inner wall of the winding sleeve 5, so that the two sets of rotating shafts 4 and the winding sleeve 5 are fixed. With the pressure rod 8 sleeved in the embedding groove 54, the winding sleeve 5 rotates simultaneously when the rotating shaft 4 rotates, thereby ensuring the power of the winding sleeve 5 when winding, and preventing the winding sleeve 5 from slipping and causing the base paper to be wound up;

[0066] When the rotating shaft 4 and the winding sleeve 5 roll down from the discharge plate 13, the locking piece 713 on the mounting plate 71 is adjusted so that the mounting plate 71 can slide relative to the rotating shaft 4. In this way, the mounting plate 71 will drive the pressure rod 8 to move outward, thereby releasing the restriction of the movable rod 51 by the pressure rod 8, and then the movable rod 51 drives the U-shaped rod 52 back to its original position. At this time, the two sets of rotating shafts 4 can be removed from the winding sleeve 5, and then a new winding sleeve 5 can be installed and placed on the two guide plates 14.

[0067] A winding method for a base paper laminating winding device, the method being applied to the base paper laminating winding device as described above, the method comprising the following steps:

[0068] Step S1: First, several groups of rotating shafts 4 with winding sleeves 5 on the outer periphery are placed in the opposite notches 31 on the two groups of rotating disks 3, and then one group of rotating shafts 4 with winding sleeves 5 on the outer periphery is placed on the two guide plates 14;

[0069] Step S2: The cut end of the base paper is placed on the uppermost surface of the winding sleeve 5, and the pressing mechanism 7 is used to move the pressing rod 8 downward to clamp the base paper, and then the winding motor 12 is used to rotate the rotating shaft 4 and the winding sleeve 5 to rewind the base paper;

[0070] Step S3: before the winding sleeve 5 at the highest position finishes winding the base paper, the downward pressing mechanism 7 on the rotating shaft 4 at the front end of the winding sleeve 5 is controlled to rotate so that the two pressure rods 8 at this position rotate to a state perpendicular to the rotating shaft 4, and then the turntable 3 is rotated by the positioning motor 11 to rotate the set of rotating shafts 4 to the top, and then the pressure rods 8 are rotated to a state parallel to the rotating shaft 4, and then the downward pressing mechanism 7 is used to move the pressure rods 8 downward, thereby clamping the base paper, and at the same time, the base paper is cut by the cutter 82, and the rotating shaft 4 rotates at the same time to make the winding sleeve 5 wind up the base paper, thereby realizing continuous winding of the base paper;

[0071] Step S4: When the top winding sleeve 5 completes winding and reaches above the discharge plate 13, the telescopic member 61 here contracts the limit plate 62, and the restriction on the rotating shaft 4 is released. The rotating shaft 4 will roll along the notch 31 to make the winding sleeve 5 and the wound base paper roll down from the discharge plate 13, thereby completing automatic unloading.

[0072] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and modifications fall within the scope of the invention as claimed.
