[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] It should be noted that in this embodiment, the directions or positional relationships indicated by "upper", "lower", "front", "back", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present application. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0043] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0044] like Figure 1 As shown, in this embodiment, a roll paper slicing device is provided, which includes a frame 11, a rolling cutting assembly 12 and an unwinding device 13. The frame 11 is the main bearing component, and it can be a frame structure of various forms, as long as the overall stability of the device is ensured. The unwinding device 13 includes an unwinding roller 131 rotatably arranged on the frame 11 and an unwinding guide assembly 132 installed on the frame 11. A roll paper is placed on the unwinding roller 131. The paper roll can be wound on the unwinding roller 131, and the paper roll is introduced into the unwinding guide assembly 132 in the form of a paper tape 16 in a rotating manner, and the unwinding guide assembly 132 is used to introduce the paper tape 16 into the rolling cutting assembly 12.

[0045] It should be noted that the rolling assembly 12 includes a rolling disc 121 rotatably disposed on the frame 11 and a rolling cutter 122 mounted on the outer periphery of the rolling disc 121. Figure 4 When the paper tape 16 enters the rolling and cutting assembly 12 under the guidance of the unwinding guide assembly 132 , it can contact the rolling cutter 122 in the rolling and cutting assembly 12 , so that the paper tape 16 is rolled and cut by the pressure of the rolling cutter 122 on the paper tape 16 .

[0046] In other words, by installing the unwinding roller 131 on the frame 11, it is convenient for the operator to place the paper roll on the unwinding roller 131, and installing the unwinding guide assembly 132 on the frame 11 can provide a guiding effect for the paper tape 16, and installing the rolling cutter 121 on the frame 11 and making the rolling cutter 121 rotatably connected to the frame 11, so that the rolling cutter 122 can roll and cut the paper tape 16 under the rotation of the rolling cutter 121, thereby achieving a shearing effect on the paper tape 16.

[0047] Since the paper roll is arranged on the unwinding roller 131 in a winding manner, the paper roll can be output in the form of a paper tape 16 when the unwinding roller 131 is rotated directly or indirectly. Of course, there are many ways to rotate the unwinding roller 131, such as manually pulling the head of the paper tape 16, and unwinding it through the unwinding guide assembly 132 and the rolling cutter 121 in sequence, and then controlling the rotation of the rolling cutter 121 to achieve rolling cutting of the pulled paper tape 16, that is, when the rolling cutter 121 rotates, since the rolling cutter 121 or the rolling cutter 122 has a certain pressure on the paper tape 16, when the rolling cutter 121 rotates automatically, the paper tape 16 can be automatically pulled out at the same time and unrolled in the unwinding guide assembly. Under the action of 132, the paper tape 16 at the pulling position moves along a fixed moving path. When the rolling cutter 122 contacts the paper tape 16, the paper material can be cut off from the paper tape 16 under the pulling force of the rolling cutter 121 on the paper tape 16 and the pressure of the rolling cutter 122 on the paper tape 16; or a motor drive or the like is adopted to realize the rotation of the unwinding roller 131 and automatic unwinding, that is, the unwinding roller 131 is externally connected to a motor, and the motor drives the unwinding roller 131 to rotate, so that the roll paper is introduced into the rolling cutter assembly 12 in the form of a paper tape 16, and the shearing of the paper tape 16 is completed.

[0048] In addition, the shape of the cut paper depends on the shape of the rolling cutter 122. For example, when the rolling cutter 122 is circular, the shape of the cut paper is also circular. Similarly, when the rolling cutter 122 is triangular, the shape of the cut paper is also triangular. For example, when the rolling cutter 122 is quadrilateral, the shape of the cut paper is also quadrilateral. This will not be described in detail here. In the embodiment of the present utility model, the shape of the rolling cutter 122 includes but is not limited to the above-mentioned circular, triangular, quadrilateral, etc. The number of the rolling cutters 122 on the rolling cutter disc 121 is at least two, and the two rolling cutters 122 are arranged in an array along the circumferential direction of the rolling cutter disc 121, and the shapes of the two rolling cutters 122 can be the same or different.

[0049] In summary, when the paper tape 16 is cut, the unwinding roller 131 is used to position the paper roll, the unwinding guide assembly 132 is used to guide the paper tape 16, and the rolling cutter 121 is rotated to drive the rolling cutter 122 to cut the paper tape 16, thereby realizing automatic cutting of the paper tape 16. Compared with the manual cutting method of paper pieces, the paper roll slicing equipment of the present application can realize the assembly line operation of cutting the paper tape 16, improve the efficiency of cutting the paper tape 16, and at the same time ensure that the specifications of the cut paper materials are consistent and the quality of the paper materials is uniform.

[0050] The rolling cutting assembly 12 also includes a pressing roller 123, see Figure 3The pressure roller 123 is rotatably arranged on the frame 11 and is tangent to the rolling disc 121 or the rolling cutter 122. It should be pointed out that the pressure roller 123 is tangent to the rolling disc 121 or the rolling cutter 122 in order to increase the friction between the paper tape 16 and the rolling disc 121, thereby ensuring that the pressure of the rolling cutter 122 can stably act on the paper tape 16. On this basis, by installing the pressure roller 123 on the frame 11 and making the pressure roller 123 tangential to the rolling disc 121, when cutting the paper tape 16, the friction between the paper tape 16 and the rolling disc 121 can be increased under the action of the pressure roller 123, which helps to pull the paper tape 16 to move when the rolling disc 121 rotates. At the same time, the pressure between the rolling cutter 122 and the paper tape 16 can be increased under the squeezing action of the pressure roller 123 and the rolling cutter 122, so that the rolling cutter 122 can cut paper on the paper tape 16, avoiding the situation that the paper material is not cut through by the rolling cutter 122 and cannot be separated from the paper tape 16, thereby improving the success rate of cutting paper by the roll paper slicing equipment.

[0051] Please refer to Figure 5 In this embodiment, the unwinding roller 131 includes a concentrically arranged core shaft 1311, a fixed disk 1312 and a connecting disk 1313, the core shaft 1311 is rotatably arranged on the frame 11, the fixed disk 1312 is fixedly connected to the core shaft 1311, the connecting disk 1313 passes through the core shaft 1311 and is detachably connected to the fixed disk 1312, and an annular boss 1314 is provided on the side of the fixed disk 1312 facing the connecting disk 1313, the annular boss 1314 is located on the outer periphery of the core shaft 1311, and the outer diameter of the annular boss 1314 is smaller than the outer diameters of the fixed disk 1312 and the connecting disk 1313, so as to form a space for accommodating a paper roll at the annular boss 1314 between the connecting disk 1313 and the fixed disk 1312.

[0052] By fixedly connecting the fixed disk 1312 with the core shaft 1311, the connecting disk 1313 is detachably connected to the fixed disk 1312, and a accommodating space is formed at the connection between the connecting disk 1313 and the fixed disk 1312. Therefore, when adding or replacing a paper roll to the unwinding roller 131, the connecting disk 1313 is removed from the fixed disk 1312, and then the center of the paper roll is passed through the core shaft 1311 and attached to the annular protrusion 1314 of the fixed disk 1312, and finally the connecting disk 1313 is passed through the core shaft 1311 and connected to the fixed disk 1312, so that the paper roll can be added or replaced, so that the paper roll slicing device can perform subsequent cutting operations on the added paper roll.

[0053] In this embodiment, the rolling assembly 12 further includes a rolling drive member 124. Figure 2 The rolling drive 124 is fixed on the frame 11, and its power end is connected to the rolling disc 121 to drive the rolling disc 121 to rotate. The unwinding device 13 also includes an unwinding drive 133, please refer to Figure 5The unwinding driving member 133 is fixed on the frame 11, and its power end is connected to the unwinding roller 131 to drive the unwinding roller 131 to rotate, thereby realizing the unwinding of the paper roll in the form of a paper tape 16.

[0054] By fixing the rolling and cutting drive member 124 on the frame 11 and connecting the rolling and cutting drive member 124 with the rolling and cutting disk 121, the rolling and cutting disk 121 can be driven to rotate under the drive of the rolling and cutting drive member 124, so that the rolling cutter 122 on the rolling and cutting disk 121 cuts the paper tape 16. By fixing the unwinding drive member 133 on the frame 11 and connecting the unwinding drive member 133 with the unwinding roller 131, the unwinding roller 131 can be driven to rotate under the drive of the unwinding drive member 133 to control the unwinding roller 131 to unwind the paper tape 16 from the paper roll, so that the rolling and cutting disk 121 rolls and cuts the released paper tape 16 to cut the required paper material on the paper tape 16. It should be noted that, for the rolling and cutting drive component 124 and the unwinding drive component 133, only the rolling and cutting drive component 124 can be set or both can be set at the same time. When only the rolling and cutting drive component 124 is set, the pulling force of the rolling and cutting disk 121 can still ensure that the paper tape 16 is continuously input into the rolling cutter 122.

[0055] In addition, the above-mentioned rolling drive 124 includes any one of a servo motor, a stepper motor, and a synchronous motor to drive the rolling disc 121 to rotate. Preferably, the rolling drive 124 uses a servo motor to accurately control the rotation angle and rotation speed of the rolling disc 121, so that the rolling cutter 122 can cut the paper tape 16. Similarly, the unwinding drive 133 includes any one of a servo motor, a stepper motor, and a synchronous motor to drive the unwinding roller 131 to rotate. Preferably, the unwinding drive 133 uses a servo motor to accurately control the rotation angle and rotation speed of the unwinding roller 131, so that the unwinding roller 131 can control the moving speed of the paper tape 16.

[0056] Please refer to Figure 6 In this embodiment, the unwinding guide assembly 132 includes at least one unwinding guide roller 1321 rotatably mounted on the frame 11, and the unwinding guide roller 1321 is located between the unwinding roller 131 and the rolling cutter 121 to change the conduction direction of the paper tape 16. In other words, the paper tape 16 guided by the unwinding roller 131 may have uncertainty in direction when entering the rolling cutter 121, which may affect the shearing effect of the rolling cutter 122. Therefore, at least one unwinding guide roller 1321 is arranged between the unwinding roller 131 and the rolling cutter 121, and the paper tape 16 can be guided to the rolling cutter 121 under the guiding action of at least one unwinding guide roller 1321, so that the paper tape 16 enters the rolling cutter 121 in a fixed path, thereby ensuring the rolling cutter 122 The rolling cutter 122 is effective, and it is convenient for the rolling cutter 121 and the pressure roller 123 to cooperate with each other to achieve the rolling cutter effect of the paper tape 16.

[0057] Based on the above embodiment, the unwinding guide rollers 1321 of the present application are three, please refer to Figure 6 The three guide rollers are distributed in a triangle as a whole. Of course, the specific positions can also be adjusted according to the actual situation to ensure that the paper tape 16 can enter the rolling and cutting assembly 12 in a flat posture after being guided out. In addition, at least two unwinding guide grooves 111 are provided on the frame 11, wherein two unwinding guide rollers 1321 are respectively slidably arranged in the two unwinding guide grooves 111, and another unwinding guide roller 1321 is rotatably connected to the frame 11 through the unwinding connecting rod 113. In other words, the positions of the three unwinding guide rollers 1321 can be adjusted, and the paper tape 16 is wound around and passes through the three unwinding guide rollers 1321 in sequence. By adjusting the spacing between the three unwinding guide rollers 1321, the tension of the paper tape 16 when passing through the roll guide assembly can be adjusted.

[0058] Specifically, when the paper tape 16 becomes loose, the unwinding link 113 rotates downward to straighten the paper tape 16; when the paper tape 16 is subjected to excessive tension and becomes tight, the tight paper tape 16 pulls the unwinding link 113 to rotate upward, thereby reducing the tightness of the paper tape 16, allowing the paper tape 16 to move on the paper rolling and slicing equipment with normal tension, which is beneficial for the rolling disc 121 to roll and cut the paper tape 16.

[0059] The unwinding guide assembly 132 also includes an unwinding elastic member 1322, see Figure 6 The frame 11 is provided with an unwinding connection column 115, one end of the unwinding elastic member 1322 is connected to the unwinding connection column 115, and the other end is connected to the unwinding connecting rod 113, and the unwinding elastic member 1322 is used to provide the unwinding connecting rod 113 with a force to rotate and drive the corresponding unwinding guide roller 1321 away from the other two unwinding guide rollers 1321. It should be pointed out that, by the tension of the unwinding elastic member 1322 on the unwinding connecting rod 113, the unwinding connecting rod 113 is always subjected to a downward rotation force, and by winding the paper tape 16 through the three unwinding guide rollers 1321 in sequence and subjecting the unwinding connecting rod 113 to an upward rotation force under the tension of the paper tape 16, the tensioning effect on the paper tape 16 is achieved, so that the paper tape 16 always maintains a normal tension when moving on the roll paper slicing device, and avoids the phenomenon of the paper tape 16 being tight or loose.

[0060] Among them, the unwinding elastic member 1322 is preferably a tension spring, and the two ends of the tension spring are respectively connected to the unwinding connecting rod 113 and the unwinding connecting column 115, so that after the paper tape 16 passes through the three unwinding guide rollers 1321, the unwinding connecting rod 113 can be pulled up and rotated downward, thereby achieving the tensioning effect on the paper tape 16.

[0061] In this embodiment, the unwinding guide assembly 132 also includes an unwinding upper limit rod 117 and an unwinding lower limit rod 118 fixed on the frame 11. The unwinding upper limit rod 117 is located above the unwinding link 113 to limit the upward rotation angle of the unwinding link 113, and the unwinding lower limit rod 118 is located below the unwinding link 113 to limit the downward rotation angle of the unwinding link 113.

[0062] During the transmission process of the paper tape 16, the unwinding guide roller 1321 and the unwinding connecting rod 113 cooperate to achieve the tensioning effect on the paper tape 16. When the paper tape 16 is too tight or too loose, the unwinding connecting rod 113 drives the unwinding guide roller 1321 to rotate to automatically adjust the tension of the paper tape 16. When the unwinding connecting rod 113 abuts against the unwinding lower limit rod 118, it means that the paper tape 16 has been adjusted to the tightest state and the paper tape 16 cannot be further tightened. When the unwinding connecting rod 113 abuts against the unwinding upper limit rod 117, it means that the paper tape 16 has been adjusted to the loosest state and the paper tape 16 cannot be further loosened.

[0063] In addition, the present application also includes a winding device 14, which is substantially the same or completely the same as the unwinding device 13 in structure, but according to the unwinding and winding functions, the winding device 14 and the unwinding device 13 need to be symmetrically arranged to respectively satisfy the winding function and the unwinding function. Figure 3 and Figure 7 The reeling device 14 reels the paper tape 16 cut by the rolling disc 121, so that the operator can store and sort the reeled paper rolls conveniently, thereby avoiding the paper tape 16 released by the unwinding roller 131 being too long and not sorted out in time, thereby causing the machine to jam.

[0064] Specifically, the winding device 14 includes a winding roller 141 and a winding guide assembly 142 . The winding roller 141 is rotatably connected to the frame 11 to wind up the paper tape 16 . The winding guide assembly 142 is installed on the frame 11 to provide guidance for the paper tape 16 .

[0065] By installing the winding roller 141 on the frame 11, after the rolling disk 121 completes the rolling and cutting operation on the paper tape 16, the winding roller 141 will rewind the rolled and cut paper tape 16, and the winding guide assembly 142 is installed on the frame 11 to provide a guide for the rolled and cut paper tape 16, thereby preventing the paper tape 16 from becoming loose or tangled when the winding roller 141 is performing the winding operation on the paper tape 16.

[0066] See also Figure 7 In this embodiment, the winding guide assembly 142 includes at least one winding guide roller 1421 installed on the frame 11, and the winding guide roller 1421 is located between the winding roller 141 and the rolling disc 121.

[0067] By setting at least one winding guide roller 1421 between the winding roller 141 and the rolling disc 121, the paper tape 16 on the rolling disc 121 can be guided to the winding roller 141 under the guiding action of at least one winding guide roller 1421, so that the winding roller 141 can wind up the paper tape 16 after rolling.

[0068] On this basis, the number of winding guide rollers 1421 can be set to three, and at least two winding guide grooves 112 are opened on the frame 11, wherein two winding guide rollers 1421 are respectively slidably connected to the two winding guide grooves 112, and the other winding guide roller 1421 is rotationally connected to the frame 11 through the winding connecting rod 114.

[0069] By setting three winding guide rollers 1421, and slidingly connecting two of the winding guide rollers 1421 to the winding guide grooves 112 on the frame 11, the position of the winding guide roller 1421 in the winding guide grooves 112 can be adjusted as needed, and the other winding guide roller 1421 is rotatably connected to the frame 11 through the winding connecting rod 114, so that when the winding guide roller 1421 pulls the paper tape 16 for guiding, the paper tape 16 can be tensioned under the rotation of the winding connecting rod 114, that is, when the paper tape becomes loose, the winding connecting rod 114 rotates downward to straighten the paper tape 16; when the tension on the paper tape 16 is too large and causes it to be tight, the tight paper tape 16 pulls the winding connecting rod 114 to rotate upward, thereby reducing the tightness of the paper tape 16, so that the paper tape 16 maintains normal tension and moves on the roll paper slicing device 1, which is beneficial to the rolling cutting disk 121 to roll the paper tape 16.

[0070] Similarly, the winding guide assembly 142 also includes a winding elastic member 1422 . A winding connecting column 116 is provided on the frame 11 . One end of the winding elastic member 1422 is connected to the winding connecting column 116 , and the other end is connected to the winding connecting rod 114 .

[0071] By arranging a winding connection column 116 connected to a winding elastic member 1422 on the frame 11, and connecting the other end of the winding elastic member 1422 to the winding connecting rod 114, the winding connecting rod 114 can always be subjected to a downward rotational force under the pulling force of the winding elastic member 1422 on the winding connecting rod 114, and the paper tape 16 is wound around the three winding guide rollers 1421 in sequence and the winding connecting rod 114 is subjected to an upward rotational force under the pulling force of the paper tape 16, thereby achieving a tensioning effect on the paper tape 16, so that the paper tape 16 always maintains a normal tension when moving on the roll paper slicing device 1, thereby avoiding the phenomenon of the paper tape 16 being tight or loose.

[0072] Among them, the winding elastic member 1422 is preferably a tension spring, and the two ends of the tension spring are respectively connected to the winding connecting rod 114 and the winding connecting column 116, so that after the paper tape 16 passes through the three winding guide rollers 1421, the winding connecting rod 114 can be pulled up and rotated upward, thereby realizing the tensioning effect on the paper tape 16.

[0073] In this embodiment, the winding guide assembly 142 also includes a winding upper limit rod 119 and a winding lower limit rod 110 fixed on the frame 11. The winding upper limit rod 119 is located above the winding link 114 to limit the upward rotation angle of the winding link 114, and the winding lower limit rod 110 is located below the winding link 114 to limit the downward rotation angle of the winding link 114.

[0074] By setting a winding upper limit rod 119 on the frame 11 to limit the upward rotation angle of the winding link 114, and setting a winding lower limit rod 110 to limit the downward rotation angle of the winding link 114, the winding guide roller 1421 and the winding link 114 can cooperate to achieve the tensioning effect on the paper tape 16 during the transmission process of the paper tape 16. When the paper tape 16 is too tight or too loose, the winding link 114 drives the winding guide roller 1421 to rotate to automatically adjust the tension of the paper tape 16. When the winding link 114 abuts against the winding lower limit rod 110, it means that the paper tape 16 has been adjusted to the tightest state and the paper tape 16 cannot be further tightened. When the winding link 114 abuts against the winding upper limit rod 119, it means that the paper tape 16 has been adjusted to the loosest state and the paper tape 16 cannot be further loosened.

[0075] In addition, the winding device 14 further includes a winding driving member 143 . The winding driving member 143 is fixed on the frame 11 and connected to the winding roller 141 to drive the winding roller 141 to rotate.

[0076] By fixing the winding drive 143 on the frame 11 and connecting the winding drive 143 to the winding roller 141, the winding roller 141 can be driven by the winding drive 143 to rotate, so as to control the winding roller 141 to wind the paper tape 16 from the rolled and cut paper tape 16 onto the winding roller 141, so as to avoid the phenomenon that the paper tape 16 is not wound up in time and causes the paper tape 16 to get stuck.

[0077] Preferably, the winding drive component 143 includes any one of a servo motor, a stepper motor, and a synchronous motor to drive the winding roller 141 to rotate. Preferably, the winding drive component 143 adopts a servo motor to accurately control the rotation angle and rotation speed of the winding roller 141, so that the winding roller 141 can control the winding speed of the paper tape 16.

[0078] Also, please refer to Figure 1The paper roll slicing device 1 further includes a control module 15, which is mounted on the frame 11 to control the device to slice the paper tape 16. Further, the control module 15 is connected to the unwinding device 13, the rolling and cutting assembly 12 and the rewinding device 14 by signals, so as to respectively control the unwinding device 13 to unwind the paper roll, control the rolling and cutting assembly 12 to roll and cut the paper tape 16, and control the rewinding device 14 to rewind the paper tape 16 after roll cutting.

[0079] By installing the control module 15 on the frame 11 , an operator can control the operation or stop of the roll paper slicing device 1 through the control module 15 .

[0080] Specifically, the control module 15 is electrically connected to the unwinding drive 133, the rolling and cutting drive 124, and the winding drive 143, so as to respectively control the unwinding drive 133 to drive the unwinding roller 131 to unwind the paper roll, control the rolling and cutting drive 124 to drive the rolling and cutting disk 121 to rotate and realize the rolling and cutting of the paper tape 16 under the cutting of the rolling cutter 122, and control the winding drive 143 to drive the winding roller 141 to rewind the rolled and cut paper tape 16. The operator can manually control each link in the roll paper slicing device 1 through the control module 15, so as to troubleshoot the fault through the control module 15 when the roll paper slicing device 1 fails.
