Description

Technical Field

[0001] The invention relates to the field of paper storage structures, in particular to a single-blade double-rotation synchronous cutting and non-speed difference paper stacking device. Background Art

[0002] As a single-blade dual-rotation fully synchronous slitting equipment for high-precision paper slitting, it is mainly used for precision paper slitting. It can slit the rewound paper roll into paper with specifications within the width, a cutting length deviation of less than 0.15mm, and a squareness of less than 0.3mm according to the needs of the downstream packaging or printing market.

[0003] In order to complete the paper slitting, the single-blade double-rotation fully synchronous slitting equipment includes a base paper rack, a paper feeding system, a slitting system, a paper conveying system, etc. The base paper rack is a paper roll positioning device. The paper feeding system ensures that the paper enters the slitting system smoothly, and is equipped with a tension control detection system. At the same time, the roll diameter detection system will control the anti-curling flattening device to press down according to the size of the paper roll diameter, thereby achieving the flattening effect on the paper. The slitting system includes a longitudinal slitting system and a transverse slitting system. Among them, the longitudinal slitting system is initially set according to the paper width requirements, and the slitting knife structure controlled by a servo motor can realize automatic knife arrangement. The transverse slitting system uses two sets of servo motors as the power source to synchronously tangent the rotary knife rollers in the opposite direction, and realizes the synchronous precision size transverse cutting function of the paper length at different vehicle speeds, speed-up process, and speed-down process. Paper conveying system: It is divided into high-speed conveying and low-speed conveying parts. The high-speed conveying part allows the paper to quickly leave the transverse cutting area after transverse cutting, and the low-speed conveying part realizes the purpose of paper stacking, while reducing the paper conveying speed, providing a reasonable working condition for the paper handling system.

[0004] In order to facilitate the orderly storage of paper, a paper storage structure is provided at the end of the paper slitting.

DETAILED DESCRIPTION

[0035] 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.

[0036] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0037] Example 1

[0038] like Figure 1 , Figure 7As shown, in order to quickly realize the replacement of the paper storage device and avoid the influence of the replacement of the storage device on the paper slitting, this embodiment provides a new storage device for the slitting device. The storage device includes a guide frame 1 and multiple groups of supporting components 3, and the multiple groups of supporting components 3 are movably arranged on the guide frame 1. The top of the supporting component 3 is detachably provided with a support plate 31, and the height of the support plate 31 can be adjusted according to the thickness of the paper stack, so that the slit paper stack can be set on the support plate 31. When multiple sheets of paper are stacked and supported on the support plate 31, at least two groups of supporting components 3 can be controlled to move synchronously, so that the supporting component 3 full of paper deviates from the slitting device, and the other supporting component 3 moves to the position facing the slitting device, and then the replacement of the supporting component 3 is completed in the gap between the two sheets of paper, which changes the current situation that the staff uses forklifts and other equipment to transfer the storage device, and correspondingly reduces the influence of the replacement of the storage device on the paper slitting. After the support plate 31 full of paper deviates from the slitting device, the staff can use forklifts and other equipment to transfer it in a relatively ample time.

[0039] like Fig.12 As shown, in order to enable the support component 3 to move at the end of the slitting device, the guide frame 1 is configured as a frame structure and is configured perpendicular to the slitting device. Therefore, the support component 3 can be controlled to move along the length direction of the guide frame 1 under the action of external force, that is, the support component 3 moves along the width direction of the slitting device, providing support for the replacement of the two groups of support components 3.

[0040] like Fig.10 As shown, in order to realize the movement of the supporting assembly 3, the supporting assembly 3 includes a lifting frame and a plurality of second pulleys 39. The support plate 31 is detachably arranged on the top of the lifting frame. Connecting shafts 38 are respectively penetrated at both ends of the bottom of the lifting frame. A second pulley 39 is provided at the end of each connecting shaft 38 through a bearing connecting sleeve. The second pulley 39 is supported on the guide frame 1, that is, the top of the guide frame 1 penetrates the second pulley 39. Therefore, under the action of the second pulley 39, not only the supporting assembly 3 is stably installed on the guide frame 1, but also support is provided for controlling the movement of the supporting assembly 3.

[0041] like Figure 7 , Figure 8As shown, in addition, a moving assembly 4 is also arranged on the guide frame 1, and the moving assembly 4 includes a second motor 41, a second belt 43 and two second pulleys 42. The two second pulleys 42 are respectively arranged at the two ends of the inner side of the second belt 43, and the central axis is installed on the guide frame 1 through a bearing seat. Therefore, under the action of the second pulley 42, the second belt 43 can be stably installed on the guide frame 1. The central axis of one of the second pulleys 42 is connected to the output shaft of the second motor 41. The second motor 41 is installed on the guide frame 1. Therefore, when the second motor 41 is working, the second pulley 42 can be controlled to rotate, thereby driving the second belt 43 to rotate. Because the second belt 43 is connected to the connecting shaft 38 of the supporting assembly 3, when the second belt 43 rotates, the supporting assembly 3 can be controlled to move.

[0042] like Figure 8 As shown, in order to realize the disassembly connection between the second belt 43 and the connecting shaft 38, a plurality of first clamps 44 are arranged at equal intervals on the second belt 43, a second clamp 47 is arranged on the side of the first clamp 44, and a clamping groove 45 and a clamping column 46 are respectively arranged on the end faces where the first clamp 44 and the second clamp 47 contact each other, the central angle of the clamping groove 45 is greater than 180°, the clamping column 46 is located in the clamping groove 45, and the connecting shaft 38 passes through the space formed by the first clamp 44 and the second clamp 47. Therefore, the first clamp 44 and the second clamp 47 can be stably connected with the cooperation of the clamping groove 45 and the clamping column 46, and at the same time, it is convenient to remove the restrictions of the first clamp 44 and the second clamp 47 according to needs and manually transfer the supporting assembly 3.

[0043] like Figure 8 As shown, in order to make the first clamping plate 44 and the second clamping plate 47 more stably connected, the central angle of the second clamping plate 47 and the first clamping plate 44 is set to 180°, and a rubber layer is provided on the arc-shaped side walls of the first clamping plate 44 and the second clamping plate 47 that are close to each other. If the clamping column 46 is to be installed in the clamping groove 45, it is necessary to press down the second clamping plate 47 to force the rubber layer to deform. When the clamping column 46 is installed in the clamping groove 45, the rubber layer has a tendency to recover the deformation, forcing the first clamping plate 44 and the second clamping plate 47 to move away from each other, thereby increasing the resistance of the clamping column 46 and the clamping groove 45 to move relative to each other, and realizing the stable connection between the first clamping plate 44 and the second clamping plate 47.

[0044] like Fig.10As shown, in order to be able to adjust the height of the support plate 31 according to needs and realize the storage of multiple sheets of paper, the lifting frame includes a lifting frame 32, a bottom frame and multiple support plates 35, two connecting shafts 38 are set through both ends of the bottom frame, the lifting frame 32 is arranged in parallel above the bottom frame, and the multiple support plates 35 are evenly divided into two groups. The two groups of support plates 35 are distributed on both sides of the space formed by the lifting frame 32 and the bottom frame, and each group of support plates 35 is arranged as a scissor-type structure. Therefore, it is set to an adjustable state. Therefore, the position of the support plate 31 can be adjusted by adjusting the state of each group of support plates 35.

[0045] like Fig.10 As shown, in order to adjust the state of each group of support plates 35, the same side end corners at the upper and lower ends of each group of support plates 35 are respectively hingedly connected to the lifting frame 32 and the bottom frame through shafts, bearings and other devices, and the other side end corners are provided with a first pulley 33, and a limiting frame 34 is penetrated through the edge of the first pulley 33. The limiting frame 34 is fixedly connected to the lifting frame 32 or the bottom frame. This arrangement can control the movement of one end of each group of support plates 35 under the action of external force, thereby adjusting the state of each group of support plates 35.

[0046] In order to achieve a detachable connection between the support plate 31 and the lifting frame 32, a socket 311 and a socket 321 are respectively provided on the lifting frame 32 and the support plate 31, and the insertion rod 311 is inserted into the socket 321 to achieve a stable connection between the lifting frame 32 and the support plate 31 and provide convenience for disassembling the support plate 31.

[0047] like Fig.10 As shown, in order to control the movement of the end of each group of support plates 35, a nut is fixedly provided in the middle of the connecting shaft 38 passing through the first pulley 33, and a lead screw 37 is threadedly provided at the nut. The end of the lead screw 37 is connected and installed on the bottom frame through a bearing seat. Therefore, by controlling the rotation of the lead screw 37, the movement of the end of each group of support plates 35 can be forced to achieve the adjustment of the position of the support plate 31.

[0048] like Figure 7 , Fig. 9As shown in the figure, since multiple sets of supporting components 3 are adjustably arranged on the guiding frame 1, in order to control the supporting component 3 that moves to the side directly opposite to the slitting device to change its own height and realize the adjustment of the position of the supporting plate 31, a driving component 5 is also arranged on the guiding frame 1. The driving component 5 includes a third motor 51, a bracket 53, and a diagonal bracing plate 56. The bracket 53 is arranged in a U-shaped structure with an upward opening and is installed below the guiding frame 1. Two sliding slots 57 are symmetrically arranged at the bottom of the bracket 53, and the ends of the sliding slots 57 are open. In addition, a bidirectional screw is penetrated through the bottom of the bracket 53, and the threaded part of the bidirectional screw is arranged facing the sliding slots 57, and the end of the bidirectional screw protruding from the bracket 53 is connected to the power output shaft of the fourth motor 54 through a coupling or the like. Therefore, the rotation of the bidirectional screw can be controlled under the operation of the fourth motor 54. Two diagonal bracing plates 56 are symmetrically arranged, and a fixed frame is hinged at the top. At the same time, a sliding clamping plate 55 is hinged at the bottom. The sliding clamping plate 55 is located in the sliding slot 57, and the bidirectional screw thread penetrates through the sliding clamping plate 55. Therefore, the movement of the sliding clamping plate 55 can be controlled when the bidirectional screw rotates, and then the inclination angle of the diagonal bracing plate 56 can be adjusted to realize the adjustment of the height of the fixed frame. Since the third motor 51 is installed on the fixed frame, the third motor 51 can be controlled to move on both the upper and lower sides of the guiding frame 1 according to the movement needs of the supporting component 3, providing support for controlling the rotation of the lead screw 37.

[0049] As Fig. 9 , Fig.10 shown in the figure, in order to control the rotation of the lead screw 37, a driving gear 52 is arranged on the power output shaft of the third motor 51, and a driven gear 36 is arranged at the end of the lead screw 37. The driven gear 36 can be meshed with the driving gear 52. That is, when the supporting component 3 moves to the side directly opposite to the slitting device, the third motor 51 moves up and down to make the driving gear 52 and the driven gear 36 meshed. Therefore, the rotation of the lead screw 37 can be controlled under the operation of the third motor 51.

[0050] This device can be installed at the end of a single-knife double-rotary synchronous slitting device, and the motor can be set as a servo motor. At the same time, the motor is connected to the servo control center of the single-knife double-rotary synchronous slitting device. The servo control center includes a microprocessor or a digital signal processor (DSP), a power amplification module (such as a power transistor), a signal conditioning module, etc., and it can execute a PID control algorithm. The servo control center is the core control unit of the entire servo system. It is mainly responsible for receiving external instructions, such as position, speed, or torque instructions from a host computer (PLC, industrial computer, etc.), and then accurately controlling the operating state of the servo motor according to these instructions. At the same time, it will also receive information feedback from the servo motor, such as the actual position, speed, and torque of the motor, and perform real-time adjustment of the motor through internal control algorithms, so as to achieve high-precision and high-dynamic-response motor control.

[0051] The servo motor and servo control center are mainly connected by dedicated cables. These cables generally contain power lines and signal lines. For example, the power line is used to transmit the electric energy that drives the motor. Its specifications (such as wire diameter, insulation grade, etc.) should be selected according to the power of the motor to ensure that it can safely and stably provide sufficient power for the motor. The signal line is mainly used to transmit control signals and feedback signals, including the motor's speed command, position command, and the motor's encoder feedback signal (such as rotor position, speed, etc.).

[0052] Therefore, referring to the technology disclosed above, the storage device can be connected to the slitting device and work in conjunction with the slitting device to achieve paper storage.

[0053] Example 2

[0054] like Figure 1 As shown, on the basis of embodiment 1, in order to avoid the problem of uneven paper stacking, offset, wrinkles, etc. caused by the speed difference between the paper storage and the conveying mechanism of the slitting device, a conveying component 2 can also be provided at the end of the slitting device, and the conveying component 2 is arranged above the supporting component 3, and the paper is stored on the supporting component 3 under the action of the conveying component 2.

[0055] like Figure 2 , Figure 4 As shown, specifically, the conveying assembly 2 includes an endless belt 21 and two support plates 24; the ends of the support plates 24 are fixedly arranged on the slitting device, and the sides of the two support plates 24 close to each other are connected to the first belt 241 through the first pulley 242, and the central axis of one of the first pulleys 242 is connected to the first motor 243 through a sprocket and a chain, so that the first belt 241 can be controlled to rotate under the action of the first motor 243. The endless belt 21 is arranged between the two support plates 24, and the two first belts 241 are respectively fixedly arranged on the inner side of the edge of the endless belt 21. When the first belt 241 rotates, the endless belt 21 rotates synchronously, so that the endless belt 21 can receive the paper output by the slitting device without speed difference. The belt and the pulley can be set as a synchronous belt and a synchronous pulley. The endless belt 21 can be connected to the belt by bolts, or can be connected by welding, or the endless belt 21 and the belt can be connected by other methods.

[0056] like Figure 2 , Figure 3As shown, in order to store the paper on the supporting assembly 3 under the action of the endless belt 21, a bending plate 22 is provided at the end of the endless belt 21. The central angle of the bending plate 22 is greater than 180°, and there is a gap between the bending plate 22 and the endless belt 21. Therefore, when the endless belt 21 carries the paper and moves to the bending plate 22, the paper is bent and moved to the bottom of the endless belt 21 under the action of the bending plate 22, and then falls on the supporting assembly 3. In addition, a plate body can be provided under the endless belt 21, and the two ends of the plate body are installed on the support plate 24 to block the paper from escaping from the endless belt 21, so as to facilitate the orderly storage of the paper in the supporting assembly 3.

[0057] like Figure 5 As shown, in order to ensure that the bending plate 22 is stably installed on the supporting plate 24, a sleeve 221 is fixedly provided at the end of the bending plate 22, a connecting rod 222 is penetrated through the sleeve 221, a fitting plate 224 is fixedly provided on the side of the connecting rod 222, a snap column 223 is fixedly provided on the inner side wall of the fitting plate 224, a snap groove 244 is provided at the end of the supporting plate 24, the fitting plate 224 is fitted to the supporting plate 24, and the snap column 223 is located in the snap groove 244.

[0058] like Figure 2 , Figure 6 As shown, in order to keep the paper still relative to the endless belt 21 when the paper passes through the bending plate 22, a negative pressure mechanism 23 is arranged between the two support plates 24, and the negative pressure mechanism 23 includes a bin body 231 and an air pump 235 (which can also be set as a vacuum pump). The bin body 231 is stably installed on the inner side of the two support plates 24 through a connecting plate 234, and is set so that the top of the opening contacts the endless belt 21, and a sealing layer 232 is arranged at the contact position between the bin body 231 and the endless belt 21; the air pump 235 is installed on the outer side of the support plate 24, and the air inlet is connected to the joint 233 at the bottom of the bin body 231 through a pipeline. Therefore, under the action of the air pump 235, the gas above the endless belt 21 can be adsorbed into the bin body 231 through the air hole 211, and finally discharged from the air pump 235. In this process, the paper can be forced to adhere to the endless belt 21, and the endless belt 21 can be stably passed through the bending plate 22. When the paper moves to the bottom of the endless belt 21 , the air pressure on it is removed, and the paper falls onto the supporting assembly 3 under the action of gravity.

[0059] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0060] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
