Description

Technical Field

[0001] The invention relates to the technical field of printing devices, in particular to an automatic wheel reel with a clamping function. Background Art

[0002] The automatic wheel winder is an industrial equipment, which is mainly used to automatically wind various strip or sheet materials (such as paper, plastic film, tape, cloth, etc.) onto a reel to form a neat roll product, so as to facilitate the storage, transportation and subsequent processing of the materials.

[0003] The working principle of the traditional automatic winder is usually that the coil is pulled by the traction device and then rolled on the air shaft. The strength of the air shaft directly affects the accuracy of the coil. As the diameter of the coil increases, the air shaft is very likely to bend and deform, causing the coil to wrinkle, which makes it impossible to rewind the material. Secondly, when facing the collection of wide-width and large-diameter coils, the traditional automatic winder cannot collect them normally due to the weight of the coil and the weight concentrated in the middle. For this reason, we propose an automatic wheel winder with a clamping function. Summary of the invention

[0006] Preferably, a guide rail is fixedly connected to the outer side of the mounting plate, and the mounting plate is slidably connected to the square support rod through the guide rail. A driving assembly is provided on one side of the mounting plate, and a rotating shaft is rotatably connected to the driving assembly.

One end of the rotating shaft is fixedly connected to a clamping head, and the clamping head is fixedly connected to one side of the corresponding first and second material rolls. One side of the driving assembly is provided with an oil cylinder fixedly connected to one side of the mounting plate, and the other end of the oil cylinder is fixedly connected to the corresponding first gear disc or the second gear disc.

[0010] Preferably, the tensioning assembly includes a tensioning bracket, which is fixedly connected to one end of the square support rod, and a guide roller is slidably connected to the inner side of the tensioning bracket. A rubber roller is arranged behind the guide roller, and the rubber roller is fixedly connected to the tensioning bracket. A tensioning cylinder is arranged at the rear end of the guide roller, and the other end of the tensioning cylinder is fixedly connected to the tensioning bracket.

[0011] Preferably, a driving gear is meshed below the front end of the second gear disc, and the driving gear is rotatably connected to the wheel disc bracket.

[0012] Preferably, a step is provided on one side of the material receiving bracket, and the step is designed to have two layers.

[0013] Preferably, a control panel is provided at the rear end of the wheel support.

[0014] Compared with the prior art, the present invention provides an automatic wheel reel with a clamping function, which has the following beneficial effects: 1. By starting the oil cylinder, the output end of the oil cylinder will drive the corresponding mounting plate to move, and the movement of the mounting plate will drive the rotating shaft to move. The movement of the rotating shaft can conveniently drive the clamping head to fix the corresponding thin paper core. After one end of the paper strip material is fixedly wound on the first material roll, the rotating shaft can be driven to rotate through the driving component. The rotation of the rotating shaft will drive the clamping head to rotate, thereby realizing the rotation and winding of the first material roll. Compared with the air-expansion shaft, this air-free shaft winding will not bend and deform due to the excessive weight of the coil, which will cause the coil to wrinkle, and then cause the material to be unable to be wound. The performance is more reliable when collecting wide-format and large-diameter coils.

[0015] 2. When the first material roll has been wound for a period of time and the winding diameter of the first material roll reaches the predetermined diameter, the driving components on both sides of the second material roll will be started. Driven by the driving components, the second material roll will reach the same speed as the first material roll. At this time, the output end of the first cylinder will drive the material receiving wall plate to move on the upper end of the wheel bracket. The movement of the material receiving wall plate will drive the pressing roller and the cutting knife to move backward at the same time. When the pressing roller and the second material roll are in contact, the cutting knife will also cut the paper strip material. At this time, the second material roll can be rotated to realize the winding of the paper strip material by the second material roll, so that the paper strip material can be docked without stopping the equipment during winding, thereby improving the winding efficiency.

[0016] 3. By driving the gear to rotate, the first gear disc and the second gear disc will rotate, and the second material roll will be rotated to the position of the first material roll, completing the position exchange between the first material roll and the second material roll, so that the second material roll is above the unloading platform, which can facilitate the unloading of the second material roll after the winding is completed.

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.

[0020] See also Figure 1-6 An automatic wheel reel with a clamping function comprises a wheel bracket 1, a material receiving bracket 2 is fixedly connected to the front end of the wheel bracket 1, a material unloading platform 26 is arranged at the rear end of the material receiving bracket 2, a wheel structure is rotatably connected to the inner side of the wheel bracket 1, the wheel structure comprises two clamping units, a first material roll 11 and a second material roll 12 are clamped on the two clamping units respectively, each clamping unit comprises two clamping assemblies, the first material roll 11 and the second material roll 12 are respectively arranged between two corresponding clamping assemblies, the wheel structure comprises a first toothed disc 3 and a second toothed disc 4, a square support rod 5 is fixedly connected between the first toothed disc 3 and the second toothed disc 4, the clamping assembly comprises a mounting plate 7, the mounting plate 7 is slidably connected to the square support rod 5, and two tensioning assemblies are arranged diagonally on the outer side of the square support rod 5.

[0021] In this embodiment, a guide rail 6 is fixedly connected to the outer side of the mounting plate 7, and the mounting plate 7 is slidably connected to the square support rod 5 through the guide rail 6. A driving assembly 8 is provided on one side of the mounting plate 7, and a rotating shaft 9 is rotatably connected to the driving assembly 8. A rotating seat is fixedly connected to the mounting plate 7, and the rotating shaft 9 is rotatably connected to the mounting plate 7 through the rotating seat. A clamping head 15 is fixedly connected to one end of the rotating shaft 9, and the clamping head 15 is fixedly connected to one side of the corresponding first material roll 11 and the second material roll 12. A cylinder 10 fixedly connected to one side of the mounting plate 7 is provided on one side of the driving assembly 8, and the other end of the cylinder 10 is fixedly connected to the corresponding first gear disc 3 or the second gear disc 4.

[0022] Specifically, two thin paper cores for winding the first material roll 11 and the second material roll 12 are respectively installed on the corresponding clamping heads 15, and the two corresponding oil cylinders 10 on the two clamping units are started at this time. The output ends of the two oil cylinders 10 will drive the corresponding mounting plates 7 to move, and the movement of the mounting plates 7 will drive the rotating shaft 9 to move. The movement of the rotating shaft 9 can conveniently drive the clamping heads 15 to fix the corresponding thin paper cores at the same time. At this time, one end of the paper strip material is fixedly wound on the first material roll 11, and then the driving component 8 is started.

When collecting rolls with wide width and large roll diameter, the performance is more reliable.

[0023] In this embodiment, the upper end of the wheel bracket 1 is slidably connected to a material receiving wall plate 19, and the rear end of the material receiving wall plate 19 is fixedly connected to a cutting knife 16. A pressing roller 17 is arranged below the cutting knife 16, and the pressing roller 17 is rotatably connected to the material receiving wall plate 19, and the pressing roller 17 is arranged in front of the second material roll 12.

The front end of the material receiving wall plate 19 is fixedly connected to the output end of the first cylinder 20, and the front end of the first cylinder 20 is fixedly connected to the wheel bracket 1.

[0024] Specifically, when the first material roll 11 is wound after a period of time and the winding diameter of the first material roll 11 reaches a predetermined diameter, the driving components 8 on both sides of the second material roll 12 will be started. Driven by the driving components 8, the second material roll 12 will reach the same speed as the first material roll 11. At this time, the first cylinder 20 is started, and the output end of the first cylinder 20 will drive the material receiving wall plate 19 to move at the upper end of the wheel bracket 1. The movement of the material receiving wall plate 19 will drive the pressing roller 17 and the cutting knife 16 to move backward at the same time. When the pressing roller 17 contacts the second material roll 12, the cutting knife 16 will also cut the paper strip material. At this time, the second material roll 12 is rotated, so that the second material roll 12 can wind up the paper strip material and complete the material connection.

[0025] In this embodiment, a plurality of fixed rollers 21 are fixedly connected to the inner side of the roulette bracket 1, a plurality of floating rollers 22 are arranged behind the plurality of fixed rollers 21, paper strip materials are S-shaped cross-wound between the plurality of fixed rollers 21 and the plurality of floating rollers 22, a movable bracket 23 is arranged at the rear end of the plurality of floating rollers 22, the rear end of the movable bracket 23 is fixedly connected to the output end of the second cylinder 24, and the rear end of the second cylinder 24 is fixedly connected to the rear end of the inner wall of the roulette bracket 1.

[0026] Specifically, by adjusting the output end of the second cylinder 24, the movable bracket 23 can be easily driven to adjust the multiple floating rollers 22, and then the tension of the S-shaped cross-wound paper strip material between the multiple fixed rollers 21 and the multiple floating rollers 22 can be adjusted as needed, which can avoid wrinkling of the paper strip material when winding and improve the flatness during winding.

[0027] In this embodiment, the tensioning assembly includes a tensioning bracket, which is fixedly connected to one end of the square support rod 5.

[0029] In this embodiment, a driving gear 25 is meshed at the lower front end of the second gear disc 4 , and the driving gear 25 is rotatably connected to the wheel disc bracket 1 .

[0030] Specifically, by rotating the driving gear 25, the first toothed disc 3 and the second toothed disc 4 will be rotated, and the second material roll 12 will be rotated to the position of the first material roll 11, completing the position exchange between the first material roll 11 and the second material roll 12, so that the second material roll 12 is above the unloading platform 26, which can facilitate the convenient unloading of the second material roll 12 after the winding is completed. Through this process, the docking of the paper strip material during winding can be completed without stopping the equipment, thereby improving the winding efficiency. It should be noted that the driving force of the driving gear 25 comes from the driving motor. The driving motor is already a public technology in this technical field and is familiar and used by technicians in this field. Therefore, it is not specifically elaborated in this application document.

[0031] In this embodiment, a step 27 is provided on one side of the material receiving bracket 2, and the step 27 is designed to be two layers.

[0032] Specifically, the design of the step 27 can facilitate the staff to stand on the step 27 to operate the device.

[0033] In this embodiment, a control panel is provided at the rear end of the wheel support 1 .

[0034] Specifically, through the design of the control panel, the operator can conveniently control the equipment intelligently through the control panel, thereby improving the production efficiency.

[0035] During operation, the two thin paper cores for winding the first material roll 11 and the second material roll 12 are respectively installed on the corresponding clamping heads 15. At this time, the two corresponding oil cylinders 10 on the two clamping units are started, and the output ends of the two oil cylinders 10 will drive the corresponding mounting plates 7 to move. The movement of the mounting plates 7 will drive the rotating shaft 9 to move. The movement of the rotating shaft 9 can conveniently drive the clamping heads 15 to fix the corresponding thin paper cores at the same time. At this time, one end of the paper strip material is fixedly wound on the first material roll 11, and then the driving component 8 is started. The output end of the driving component 8 drives the rotating shaft 9 to rotate. The rotation of the rotating shaft 9 will drive the clamping heads 15 to rotate. By rotating the clamping heads 15, the first material roll 11 can be easily rotated and wound. At this time, The cooperation between the guide roller 13 and the rubber roller 14 can further adjust the tension of the paper strip material, avoid wrinkling of the paper strip material when winding, and improve the flatness of the winding. When the first material roll 11 is wound for a period of time, the winding diameter of the first material roll 11 will reach a predetermined diameter, and the driving components 8 on both sides of the second material roll 12 will be started. Driven by the driving components 8, the second material roll 12 will reach the same speed as the first material roll 11. At this time, the first cylinder 20 is started, and the output end of the first cylinder 20 will drive the material receiving wall plate 19 to move at the upper end of the wheel bracket 1. The movement of the material receiving wall plate 19 will drive the pressing roller 17 and the cutting knife 16 to move backward at the same time. When the pressing roller 17 contacts the second material roll 12, The cutting knife 16 will also cut the paper strip material at the same time. At this time, the second material roll 12 is rotated to realize the second material roll 12 to reel up the paper strip material, and then complete the material connection. At this time, the driving components 8 on both sides of the first material roll 11 are stopped, and then recovered at the output end of the oil cylinder 10. Through the cooperation of the square support rod 5 and the guide rail 6, the clamping head 15 can release the control of the first material roll 11, and then the first material roll 11 can be easily unloaded through the unloading platform 26. Similarly, a new thin paper core is installed on the clamping head 15 again, and then the oil cylinder 10 is started in the reverse direction to fix the thin paper core again. At this time, the first toothed disc 3 and the second toothed disc 4 are rotated by the driving gear 25 to rotate the second material roll 12 to the first The position of the first material roll 11 is changed to complete the exchange of the positions of the first material roll 11 and the second material roll 12, so that the second material roll 12 is located above the unloading platform 26, which can facilitate the unloading of the second material roll 12 after the winding is completed. Through this process, the docking of the paper strip material during winding can be completed without stopping the device, thereby improving the winding efficiency. At the same time, when the paper strip material is wound, the size of the winding will gradually increase. Similarly, the weight of the paper roll will also increase accordingly. Through this device, the weight of the first material roll 11 and the second material roll 12 will pass through the clamping head 15, and the final weight will be borne on the square support rod 5. Compared with the air-inflating shaft, this air-inflating shaft-free winding will not bend and deform due to the excessive weight caused by the excessive weight of the coil, resulting in wrinkling of the coil.This will cause the material to be unable to be rewound. When receiving wide-format and large-diameter rolls, the performance is more reliable.
