Description

Technical Field

[0001] The invention relates to the technical field of printing and coding reeling, in particular to an automatic reeling device for printing and coding. Background Art

[0002] A printing press is a machine for printing text and images. Modern printing presses are generally composed of mechanisms such as plate loading, inking, pressing, and paper feeding (including folding). Its working principle is: first, the text and image to be printed are made into a printing plate, which is then installed on the printing press. Then, ink is applied to the places where the text and image are on the printing plate by humans or the printing press, and then directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood boards, glass and ceramics), thereby replicating the same printed product as the printing plate. A winding device is provided on one side of the printing press, which cooperates with the paper feeding device to allow the printed paper to pass on the workbench of the printing press, which is convenient for printing and transmitting the paper tape. The existing winding device has a roughly similar structure, and the driving device drives the rotating shaft to rotate, and further drives the receiving roller to rotate, so that the printed paper tape is wound on the receiving roller. However, the existing receiving rollers are generally one or more in number. However, no matter it is one or more, when the receiving roller rewinds to a certain diameter, the equipment needs to be stopped, and then the winding material on the receiving roller is removed, and then a new receiving roller is replaced.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-Figure 7 , the present invention provides a technical solution:

[0029] An automatic winding device for printing and inkjet coding comprises a vertical plate 1, a rotating shaft 2 is rotatably connected to the vertical plate 1, a half gear 38 is installed on the rotating shaft 2, a fixed plate 3 is installed on the rotating shaft 2, two material receiving shafts 4 are rotatably connected to the fixed plate 3, a first gear 9 is installed at one end of the material receiving shaft 4, two anti-loosening mechanisms 5 are installed on the fixed plate 3, a smearing mechanism 10 is provided on the vertical plate 1, the material receiving shaft 4 can contact with the smearing mechanism 10, and the smearing mechanism 10 smears adhesive when released, a first hydraulic rod 16 is rotatably connected to the vertical plate 1, a second gear 17 is installed on the first hydraulic rod 16, and the second gear 17 is movably meshed with the first gear 9, a moving mechanism 18 is installed on the vertical plate 1, a cutting assembly 22 is installed on the lower side of the moving mechanism 18, a pushing mechanism 23 is installed on the moving mechanism 18, and a driving mechanism 28 is provided on the vertical plate 1, and the driving mechanism 28 is movably connected to the first hydraulic rod 16, the rotating shaft 2 and the moving mechanism 18 respectively;

[0030] During operation, two material receiving shafts 4 are provided on the fixed plate 3, and the two material receiving shafts 4 can be replaced, so that when one material receiving shaft 4 is wound up, the other can be wound up quickly, thereby improving the winding efficiency of the equipment. After one material receiving shaft 4 is wound up, the positions of the two material receiving shafts 4 are changed through the cooperation of the driving mechanism 28 and the rotating shaft 2. When the positions of the two material receiving shafts 4 are changed, the moving mechanism 18 is simultaneously lowered, so that the cutting assembly 22 can quickly complete the cutting of the material, and at the same time, the pushing assembly can quickly push the material to the side of the new material receiving shaft 4, so that the new material receiving shaft 4 can continue to be wound up, so that the equipment can achieve the purpose of fast winding without stopping when in use, thereby making the equipment more efficient at work, and further The winding efficiency of the equipment is further accelerated, and the equipment is more convenient to work. When the equipment is changing the position of the material-receiving shaft 4, the material-receiving shaft 4 passes through the coating mechanism 10, which makes the coating mechanism 10 coat the adhesive on the surface of the material-receiving shaft 4, so that the surface viscosity of the material-receiving shaft 4 is stronger, and then the pushing mechanism 23 pushes the material to one side of the material-receiving shaft 4, and the material-receiving shaft 4 can wind the material more quickly, so that the equipment can be wound more efficiently during operation, avoiding the situation where it cannot be wound quickly during winding. During the material-receiving process of the material-receiving shaft 4, the anti-loosening mechanism 5 can squeeze the wound material, thereby ensuring the tightness of the material during winding and preventing looseness during winding, further improving the winding efficiency and automation work efficiency of the equipment.

[0031] As a further solution of the present invention, the receiving shaft 4 is located at the lower side of the anti-loosening mechanism 5, the anti-loosening mechanism 5 includes a connecting plate 6, a first spring 7 and an extrusion plate 8, the fixing plate 3 is fixedly connected to the connecting plate 6, a plurality of first springs 7 are fixedly connected to the connecting plate 6, and an extrusion plate 8 is fixedly connected between the plurality of first springs 7, and a smooth layer is provided on the surface of the extrusion plate 8;

[0032] During operation, the extrusion plate 8 is close to one side of the receiving shaft 4. When more and more materials are wound on the receiving shaft 4, the diameter of the wound material becomes larger and larger. At this time, the extrusion plate 8 gradually squeezes the wound material. At the same time, the elastic force of the first spring 7 acts on the extrusion plate 8. The elastic force of the first spring 7 acts as an extrusion force, which can effectively prevent the equipment from becoming loose during winding, thereby further improving the winding tightness of the equipment.

[0033] As a further solution of the present invention, the smearing mechanism 10 includes a bracket 11, a smearing box 12, a mounting plate 13, a second spring 14 and a smearing plate 15. The bracket 11 is fixedly connected to the vertical plate 1, the smearing box 12 is mounted on the bracket 11, two mounting plates 13 are fixedly connected to the bracket 11, a plurality of second springs 14 are fixedly connected to the mounting plate 13, and a smearing plate 15 is fixedly connected between the plurality of second springs 14. The side of the smearing plate 15 is arc-shaped, and the smearing plate 15 and the smearing box 12 are connected through;

[0034] During operation, the smear box 12 injects the colloidal material onto the smear plate 15. When the receiving shaft 4 passes through the two smear plates 15, the elastic force of the second spring 14 acts on the smear plate 15, so that the smear plate 15 is tightly attached to the receiving shaft 4. At this time, the colloidal material on the smear plate 15 is smeared on the receiving shaft 4, and then the surface of the receiving shaft 4 contains the colloidal substance. When the pushing mechanism 23 pushes the material to one side of the receiving shaft 4, the colloidal substance adheres to the material, so that the receiving shaft 4 can quickly reel up the material, thereby forming a non-stop working state.

[0035] As a further solution of the present invention, the moving mechanism 18 includes a rotating sleeve 19, a threaded rod 20 and a limiting rod 21. The rotating sleeve 19 is rotatably connected to the vertical plate 1, the threaded rod 20 is internally threadedly connected to the rotating sleeve 19, and the limiting rod 21 is provided between the threaded rod 20 and the vertical plate 1;

[0036] During operation, when the fixed plate 3 needs to rotate, the first hydraulic rod 16 is shortened first, at which time the first gear 9 and the second gear 17 are disengaged. When the fixed plate 3 rotates, the driving mechanism 28 controls the rotation of the rotating sleeve 19 through the speed regulating box 29 at the same time. When the rotating sleeve 19 rotates, the threaded rod 20 moves under the limit of the limit rod 21. When the threaded rod 20 moves to a certain position, the detector in the cutting component 22 detects the material, and the cutting component 22 moves to cut the material. As the cutting component 22 cuts, the material is in a broken state, and the pushing mechanism 23 begins to push the broken material to one side of the receiving shaft 4. When the receiving shaft 4 starts to reel in, the moving mechanism 18 is reset, and the work is repeated, which can effectively ensure the non-stop reeling work of the equipment, making the equipment more convenient, quick and efficient when reeling in.

[0037] As a further solution of the present invention, the pushing mechanism 23 includes a second hydraulic rod 24, a support plate 25, a push plate 26 and a third hydraulic rod 27. The second hydraulic rod 24 is installed on the threaded rod 20, and a support plate 25 is installed at one end of the second hydraulic rod 24. The push plate 26 is rotatably connected to the support plate 25, and two third hydraulic rods 27 are arranged between the push plate 26 and the support plate 25.

[0038] During operation, when the moving mechanism 18 descends to a certain position, the cutting assembly 22 cuts the material. At the same time, when the material cutting is completed, the second hydraulic rod 24 pushes the support plate 25 to move. At this time, the push plate 26 installed on the support plate 25 gradually pushes the cut material to one side of the receiving shaft 4 (the specific process is: see Figure 1 Combination Figure 7, the second hydraulic rod 24 pushes the support plate 25 to move until the upper edge of the push plate 26 contacts the material receiving shaft 4 first, and then the third hydraulic rod 27 is started to extend, so that the lower edge of the push plate 26 also contacts the material receiving shaft 4, thereby achieving surface fitting between the push plate 26 and the material receiving shaft 4). At the same time, the adhesive on the material receiving shaft 4 sticks the material to the material receiving shaft 4, and then the driving mechanism 28 controls the rotation of the second gear 17, so that the material receiving shaft 4 rewinds the material. At this time, the moving mechanism 18 is reset, thereby completing the non-stop rapid rewinding of the equipment, thereby further improving the rewinding efficiency of the equipment, making the equipment more convenient and quick when rewinding; at the same time, on the premise of achieving the fit between the paper tape and the shaft body, the end of the paper tape rewinding is prevented from being loose.

[0039] As a further solution of the present invention, the push plate 26 is arc-shaped, the push plate 26 is movably connected to the receiving shaft 4, and an anti-slip layer is provided on the surface of the push plate 26;

[0040] When working, the push plate is arc-shaped, so that it is more convenient to fit with the receiving shaft 4, and it is more convenient to push the material to the side of the receiving shaft 4, and the winding efficiency is higher, which further improves the winding efficiency and convenience of the equipment.

[0041] As a further solution of the present invention, the driving mechanism 28 includes a speed regulating box 29, a first rotating column 30, a torsion spring 31, a third gear 32, a second rotating column 33, a third rotating column 34, a driving motor 35 and a telescopic rod 36. The speed regulating box 29 is installed on the vertical plate 1, and the speed regulating box 29 is transmission-connected to the moving mechanism 18. The first rotating column 30, the second rotating column 33 and the third rotating column 34 are rotatably connected to the vertical plate 1. The first rotating column 30 is transmission-connected to the speed regulating box 29. The torsion spring 31 is sleeved on the first rotating column 30. The third gear 32 is installed at one end of the first rotating column 30. The third gear 32 and the half gear 38 are movably engaged. The second rotating column 33 is transmission-connected to the first hydraulic rod 16. The third rotating column 34 is transmission-connected to the rotating shaft 2. The driving motor 35 is installed on the vertical plate 1. The output end of the driving motor 35 is fixedly connected to the telescopic rod 36, and the telescopic rod 36 is movably engaged with the second rotating column 33 and the third rotating column 34 respectively.

[0042] During operation, when the telescopic rod 36 is extended, the telescopic rod 36 and the second rotating column 33 are engaged, and at this time, the driving motor 35 controls the first hydraulic rod 16 to rotate through the second rotating column 33, and then the first gear 9 and the second gear 17 are rotated. At this time, the material receiving shaft 4 starts to reel in the material, and when the material reeling is completed, the first hydraulic rod 16 is shortened, the first gear 9 and the second gear 17 are disengaged, and the telescopic rod 36 is shortened. At this time, the telescopic rod 36 and the third rotating column 34 are engaged, and then the driving motor 35 controls the rotation of the rotating shaft 2 through the third rotating column 34, and then the positions of the two material receiving shafts 4 are exchanged, and at the same time, the half gear 38 controls the third gear 32 to rotate At the same time, the first rotating column 30 controls the moving mechanism 18 to move through the speed regulating box 29. When the cutting component 22 completes cutting, the moving mechanism 18 will move downward a certain distance. At this time, the pushing mechanism 23 pushes the cut material to the side of the receiving shaft 4. When the receiving shaft 4 completes adhesion, the half gear 38 and the third gear 32 are disengaged. At this time, the torsion spring 31 begins to reset, and then the moving mechanism 18 is reset, and the telescopic rod 36 is extended again, so that the first gear 9 and the second gear 17 are meshed and rotated again, and the material can continue to be rolled up, making the material more automated when rolling up, and at the same time, it can work without stopping during operation, further improving the working efficiency of the equipment.

[0043] As a further solution of the present invention, a self-locking component 37 is installed on the rotating shaft 2;

[0044] During operation, when the shaft 2 rotates, the self-locking mechanism opens, and when the shaft 2 stops rotating, the self-locking mechanism fixes the shaft 2, thereby ensuring the stability of the fixed plate 3 and preventing the receiving shaft 4 on the fixed plate 3 from shaking during winding.
