Description

Technical Field

[0001] The present application relates to the technical field of shearing devices, and in particular to a high-efficiency label paper shearing device. Background Art

[0002] Label paper, also known as strip paper, is widely used in daily life. With the continuous development of label paper, related equipment has also developed rapidly. In the process of label paper production, the paper needs to be cut into fixed sizes to facilitate the sticking of goods.

[0003] A Chinese patent with publication number CN218984892U discloses a shearing device for label paper production, including a base, a table, a cutter and a stand. A paper cutting groove corresponding to the cutter is opened on the table, a crossbeam is fixedly installed on the upper end of the stand, the cutter is fixedly installed on the lower end of the tool mounting plate, a hydraulic cylinder is fixedly installed on the crossbeam, the output end of the hydraulic cylinder is connected to the tool mounting plate, a protective frame is fixedly arranged on the table, a push rod is fixedly installed on the lower end of the protective frame, the output end of the push rod is fixedly connected to a pressing plate, the pressing plate is arranged at the front end of the cutter, a first baffle mechanism and a second baffle mechanism are arranged on the table, the first baffle mechanism is arranged on the left side of the pressing plate, and the second baffle mechanism is arranged on the right side of the pressing plate. The shearing device can effectively prevent the label paper from being easily wrinkled and offset by external force during the process of shearing the label paper, and can make corresponding adjustments according to the different widths of the label paper, which is convenient for popularization and application.

[0004] With regard to the above-mentioned related technologies, the inventor believes that the cutter on the cutter mounting plate is in the shape of a long strip, and in order to ensure that the waste label paper is not cut off, the label paper needs to be conveyed intermittently during the conveying process to ensure the normal operation of the next cutting operation, which leads to an increase in the overall cutting time and a decrease in cutting efficiency, which is obviously insufficient. Utility Model Content

[0005] In order to improve the cutting efficiency of label paper, the present application provides a high-efficiency label paper cutting device.

[0006] The present application provides an efficient label paper cutting device adopts the following technical solution:

[0007] A high-efficiency label paper cutting device comprises a frame, a round roller cutter and a conveyor belt rotatably connected to the frame, a rotating shaft is rotatably connected to the frame, the rotating shaft and the round roller cutter are detachably connected and fixed and coaxially arranged, a gap is formed between the conveyor belt and the round roller cutter for the label paper to pass through, and a driving component for driving the rotating shaft is provided on the frame.

[0008] By adopting the above technical solution, when the driving assembly arranged on the frame starts to work, the driving rotating shaft rotates, so that the round roller cutter also rotates. When the label paper passes through the gap between the conveyor belt and the round roller cutter, the round roller cutter starts to cut the label paper. Since the conveyor belt is always conveying, the label paper is always cut by the round roller cutter, thereby improving the cutting efficiency.

[0009] Optionally, the circular roller cutter includes two cutter sleeves with semicircular cross-sections, an integrally formed blade is provided on the cutting sleeve, an integrally formed limiting protrusion is provided on the rotating shaft, a limiting groove is provided on the semicircular cutter sleeve for plugging with the limiting protrusion, end cover rings are provided at both ends of the cutter sleeve, fasteners are provided on the end cover rings, and the end cover rings fix the rotating shaft and the two cutter sleeves through the fasteners.

[0010] By adopting the above technical solution, the limiting groove on the cutter shaft sleeve is plugged into and matched with the limiting protrusion integrally formed on the rotating shaft, and the two semicircular arc-shaped cutter shaft sleeves are fixedly connected to the rotating shaft through the end cover rings and fasteners at both ends of the front and rear ends, which is convenient for workers to install and rotate. When one of them is damaged, one of them can be replaced, thereby saving costs.

[0011] Optionally, a pad is provided on the frame, a lap groove for the pad to overlap is opened on the frame, the pad is located between the conveyor belt and the round roller cutter, and a rubber pad is provided on the pad.

[0012] By adopting the above technical solution, when the circular roller cutter is cutting the label paper, the pad provides supporting force, and the direct contact between the two rigid parts may cause damage to the circular roller cutter and wear on the pad surface, while the rubber pad can increase the service life of the circular roller cutter.

[0013] Optionally, a buffer member (81) is provided between the overlapping groove and the backing plate.

[0014] By adopting the above technical solution, the buffer member (81) arranged between the overlapping groove and the pad can effectively alleviate the impact force generated during shearing.

[0015] Optionally, a unwinding roller is provided upstream of the circular roller cutter, and a winding roller is provided downstream of the circular roller cutter. The driving assembly includes a synchronous belt, a synchronous wheel and a click arranged on the frame. The synchronous wheels are respectively fixedly mounted on the rotating shaft, the winding roller and the driving shaft of the conveyor belt close to one end of the winding roller. The motor causes the synchronous wheels to rotate simultaneously through the synchronous belt.

[0016] By adopting the above technical solution, when the motor rotates, the speeds of the conveyor belt, the winding roller and the rotating shaft are consistent through the transmission of the synchronous belt and the synchronous wheel, thereby reducing the possibility of label paper breaking.

[0017] Optionally, two limit plates are provided on the frame, the limit plates are located on both sides of the conveyor belt, and the label paper is located between the two limit plates during conveyance.

[0018] By adopting the above technical solution, the limiting plate can prevent the label paper from deviating during the transmission process, thereby reducing the unqualified rate of the finished product.

[0019] Optionally, a bidirectional screw is rotatably passed through one end of the limit plate, and a guide rod is rotatably passed through the other end. The two thread sections of the bidirectional screw are respectively threadedly connected to the limit plate, and a sliding groove is provided on the limit plate to slide with the guide rod.

[0020] By adopting the above technical solution, the bidirectional screw can adjust the distance between the limit plates according to the different models of label paper, so that it can adapt to different models of label paper. When the limit plates on both sides of the label paper approach or move away from each other, the sliding grooves on the limit plates slide in conjunction with the guide rods, making the limit plates more stable when they approach each other.

[0021] Optionally, an auxiliary roller is provided upstream of the circular roller cutter, the auxiliary roller is rotatably connected to the frame, and the label paper is passed between the auxiliary roller and the conveyor belt.

[0022] By adopting the above technical solution, before the label paper is cut by the circular roller cutter, the auxiliary roller can press the label paper to make its surface have a certain degree of flatness, thereby improving the qualified rate of the product.

[0023] Optionally, a waste roller, a glue pressing roller and a glue release roller are sequentially arranged downstream of the circular roller cutter. The waste roller, the glue pressing roller and the glue release roller are respectively rotatably connected to the frame. The glue pressing roller is located above the conveyor belt. The waste roller is located between the glue pressing roller and the conveyor belt. The gap formed between the waste roller and the glue pressing roller is used for transmitting waste label paper. An adhesive piece is fixedly sleeved on the glue release roller, and the adhesive piece is adhered to the waste label paper through the gap formed between the waste roller and the glue pressing roller.

[0024] By adopting the above technical solution, after the label paper is cut by the circular roller cutter, the waste label paper and the adhesive piece pass through the gap between the waste roller and the glue roller together, so that the adhesive piece is more firmly attached to the waste label paper, thereby increasing the tension of the waste label paper, making the waste label paper less likely to break, and improving work efficiency.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. When the driving assembly on the frame starts working, the circular roller cutter starts to cut the label paper when the label paper passes through the gap between the conveyor belt and the circular roller cutter. Since the conveyor belt is always conveying, the label paper is always cut by the circular roller cutter, thereby improving the cutting efficiency;

[0027] 2. The limiting groove on the cutter shaft sleeve is plugged into the limiting protrusion integrally formed on the rotating shaft, and the two cutter shaft sleeves are fixedly connected to the rotating shaft through the end cover rings at both ends of the front and rear ends and the fasteners, which is convenient for workers to install and rotate. When one of them is damaged, one of them can be replaced, thereby saving costs;

[0028] 3. When the round roller cutter is cutting the label paper, the pad provides support. When the working time is too long and the two rigid parts are in direct contact, the round roller cutter may be damaged and the pad surface may be worn. The rubber pad can increase the service life of the round roller cutter. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following is combined with Figure 1-4 This application is described in further detail.

[0036] The embodiment of the present application discloses a high-efficiency label paper cutting device.

[0037] refer to Figure 1A high-efficiency label paper cutting device includes a frame 1 and a conveyor belt 13. The two conveyor shafts of the conveyor belt 13 are rotatably connected to the frame 1. The frame 1 is rotatably connected with an unwinding roller 11, a winding roller 12 and a round roller cutter 5. The unwinding roller 11 is upstream of the round roller cutter 5, and the winding roller 12 is downstream of the round roller cutter 5. The label paper starts to be transmitted from the unwinding roller 11 along the direction of the conveyor belt 13. When passing through the round roller cutter 5, the label paper is cut, and then the winding roller 12 winds up the cut label paper.

[0038] Reference Figure 2 The round roller cutter 5 comprises two cutter sleeves 51 with a semicircular cross section, and a blade 52 integrally formed therewith is arranged on the outer side of the cutter sleeves 51. A rotating shaft 55 is rotatably connected to the frame 1, and the two cutter sleeves 51 are sleeved on the rotating shaft 55. The rotating shaft 55 is provided with an integrally formed limiting protrusion 551, and the limiting protrusion 551 has a rectangular cross section. A limiting groove 511 is provided on the inner side of the cutter sleeve 51 to be plugged with the limiting protrusion 551. The plugging and matching of the limiting protrusion 551 and the limiting groove 511 enables the cutter sleeve 51 to rotate with the rotating shaft 55 without relative rotation. End cover rings 53 are provided at both ends of the cutter shaft sleeve 51, and fasteners 54 are provided on the end cover rings 53. The fasteners 54 are hexagon socket screws. The end cover rings 53 fix the rotating shaft 55 with the two cutter shaft sleeves 51 through the hexagon socket screws, so that the cutter shaft sleeves 51 rotate together with the rotating shaft 55. When it is necessary to cut different types of label paper, the worker only needs to remove the hexagon socket screws on the end cover ring 53 to complete the replacement of the cutter shaft sleeve 51.

[0039] Reference Figure 1 and Figure 3 The frame 1 is rotatably provided with an auxiliary roller 2, which rotates above the conveyor belt 13 and close to the side of the unwinding roller 11. Before the label paper is conveyed to the gap formed between the auxiliary roller 2 and the conveyor belt 13, the auxiliary roller 2 can flatten the label paper. The frame 1 is rotatably connected with a round roller cutter 5, and a pad 8 is provided directly below the round roller cutter 5. The pad 8 has a square cross-section. The frame 1 is provided with an overlapping groove 14 for the pad 8 to overlap. The pad 8 is between the conveyor belt 13 and the round roller cutter 5. A rubber pad 82 is provided on the pad 8. A buffer 81 is provided between the overlapping groove 14 and the pad 8. The buffer 81 is a sponge pad.

[0040] Reference Figure 1 and Figure 4, a U-shaped cross-section limit plate 3 is arranged on both sides along the conveying direction of the conveyor belt 13, a bidirectional screw 31 is rotatably penetrated at one end of the frame 1, and a guide rod 32 is rotatably penetrated at the other end. The threaded sections at both ends of the bidirectional screw 31 are respectively threadedly connected with the two limit plates 3, the two ends of the bidirectional screw 31 are rotatably connected to the frame 1, one end extends out of the frame 1 and is fixedly connected to a hand wheel, and a sliding groove 33 that slides with the guide rod 32 is provided on the limit plate 3.

[0041] Reference Figure 1 On the frame 1, a glue release roller 6, a glue pressing roller 7 and a waste roller 4 are rotatably arranged respectively, and all three are at the downstream position of the round roller cutter 5. When the cut paper is cut by the round roller cutter 5, the waste label paper produced will pass through the gap formed between the glue pressing roller 7 and the waste roller 4. The glue release roller 6 is provided with an adhesive member 61, which is an adhesive tape. The adhesive tape will be attached to the waste label and pass through the gap formed between the glue pressing roller 7 and the waste roller 4.

[0042] Reference Figure 1 and 5 , the reel 12 is arranged on the opposite side of the unreel 11, and the waste label paper will be reeled onto the reel 12. A driving assembly 9 is arranged on the frame 1, and the driving assembly 9 includes a synchronous belt 91, a synchronous wheel 92 and a motor 93 arranged on the frame 1. The synchronous wheel 92 is respectively fixedly sleeved on the rotating shaft 55, the reel 12 and the driving shaft of the conveyor belt 13 close to the reel 12. When the motor 93 drives to rotate, the synchronous wheel 92 on the driving shaft will rotate under the action of the motor 93, and the reel 12 and the synchronous wheel 92 on the rotating shaft 55 will rotate simultaneously under the action of the synchronous belt 91. The motor 93 is fixed to the frame 1 by screws. A collection frame is arranged on one side of the end of the conveyor belt 13, and the opening of the collection frame faces the conveyor belt 13. After the label paper is cut, the finished product will fall on the conveyor belt 13 and reach the collection frame.

[0043] The implementation principle of an efficient shearing device in the embodiment of the present application is:

[0044] When the motor 93 is working, the synchronous belt 91 and the synchronous wheel 92 rotate simultaneously, and the conveyor belt 13, the winding roller 12 and the round roller cutter 5 rotate simultaneously. The label paper is limited by the U-shaped limiting plate 3 to ensure that the label paper will not deviate during the conveying process. The auxiliary roller 2 keeps the surface of the label paper flat when it is cut.

[0045] When the label paper passes through the gap between the pad 8 and the round roller cutter 5, the blade 52 integrally formed on the cutter sleeve 51 will cut the label paper. Since the conveyor belt 13 is always conveying, the round roller cutter 5 is always cutting the label paper, thereby improving the cutting efficiency.

[0046] After the label paper is cut, the finished product will be transmitted to the collection frame on the transmission, and the tape on the glue roller 6 will stick to the waste label paper. After passing through the gap formed between the glue pressing roller 7 and the waste roller 4, the tape will stick to the waste label paper better, and finally be wound on the winding roller 12.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
