Description

Technical Field

[0001] The present invention relates to the technical field of dust-free paper cutting, and in particular to a dust-free paper high-precision cutting device and method. Background Art

[0002] Dust-free paper cutting mainly relies on professional cutting equipment, which uses precise mechanical structure or laser technology to achieve dust-free paper cutting. Specifically:

[0003] Mechanical dust-free paper cutter: This type of equipment cuts dust-free paper through precise mechanical structure and cutting tools. They are usually equipped with advanced control systems to ensure cutting accuracy and efficiency. Mechanical dust-free paper cutters are suitable for dust-free paper of various specifications and thicknesses to meet different production needs.

[0004] Laser cutting technology: Laser cutting technology may be used in some high-precision or special-need dust-free paper cutting. Laser cutting uses a high-power density laser beam to irradiate the workpiece, causing the irradiated material to melt, vaporize or ablate rapidly, thereby achieving precise dust-free cutting.

[0005] When using a mechanical dust-free paper cutter to cut dust-free paper, the surface of the dust-free paper to be cut after transportation is often in a wrinkled state due to the low tension of the dust-free paper during transportation, which affects the high-precision cutting operation of the dust-free paper.

[0015] Preferably, the connecting assembly includes a fixed frame fixed to the upper end of the circular frame, a plurality of groups of second sleeves are fixed on the fixed frame, each group of the second sleeves is slidably connected with a second sliding rod, one end of the second sliding rod is fixed to a limit plate, a second spring is sleeved on the outer side of the second sleeve, the two ends of the second spring are respectively connected to the limit plate and the fixed frame, and a push plate for pressing against the end of the T-shaped limit rod is fixed on the support frame.

[0016] Preferably, the lifting assembly includes a connecting plate fixed between two groups of support frames, and a cylinder for driving the lifting plate to lift is installed on the connecting plate.

[0017] Preferably, the winding assembly includes two groups of mounting grooves opened on the machine body, a winding roller is arranged between the two groups of mounting grooves, the winding roller is rotatably connected to the two groups of mounting grooves through bearings, the dust-free paper body is rolled on the winding roller, and a supporting roller for supporting the transported dust-free paper body is arranged on the machine body.

[0018] Preferably, the conveying assembly includes two sets of mounting shafts rotatably connected to the machine body, conveying rollers are fixed on the two sets of mounting shafts, the dust-free paper body passes through between the two sets of conveying rollers and is arranged against each other, and a driving motor for driving the mounting shafts is installed on the machine body.

[0019] A high-precision cutting method for dust-free paper comprises the following steps:

[0020] S1: When using a mechanical dust-free paper cutter to cut the dust-free paper body, the end of the dust-free paper body rolled on the winding roller is passed through between the two sets of conveying rollers and abutted against each other. During the passing process, the support roller abuts against the inner side of the dust-free paper body, elastically supporting the dust-free paper body, so as to facilitate the subsequent stable and high-quality conveying operation of the dust-free paper body;

[0021] S2: After the dust-free paper body is threaded, the conveying rollers on the mounting shaft are driven to rotate by the driving motor. Since the two sets of conveying rollers are against the dust-free paper body, the dust-free paper body is driven to be conveyed by the friction between the conveying rollers and the dust-free paper body;

[0022] S3: After the dust-free paper body is conveyed to a certain length, the lifting plate is driven to move downward by the lifting assembly. During the downward movement of the lifting plate, the cutter at the lower end of the lifting plate is abutted against the dust-free paper body conveyed to a certain length above the support plate, so as to cut the dust-free paper body;

[0023] S4: In the process of cutting the dust-free paper body by descending the lifting plate, as the lifting plate descends, the two groups of pressing plates under the circular frame first abut against the surface of the dust-free paper body and are limited in the vertical direction. As the lifting plate and the circular frame continue to descend, the circular frame moves toward the abutted pressing plates. During the movement, the two groups of inclined grooves on the transmission plate interact with the two groups of transmission pins respectively, so that the two groups of pressing plates are driven to move under force;

[0024] S5: During the movement of the pressing plate, the installation plate is driven to move through the connection of the telescopic assembly. During the movement of the installation plate, the two groups of installation plates and the pressing plate are forced to move away from each other through the sliding guide of each group of T-bars. Since the pressing plate and the upper surface of the dust-free paper body are against each other, the dust-free paper body that is pressed against each other is flattened through the mutual movement of the pressing plate after being forced, thereby reducing the probability of wrinkles on the dust-free paper body to be cut, and further facilitating a more accurate cutting operation of the dust-free paper body.

[0025] S6: In the process of driving the two groups of mounting plates to move away from each other under force, as the mounting plates move, the T-shaped limit rod on the mounting plates and the inclined surface on the limit plates are offset against each other. During the offset process, the limit plates are subjected to force to perform a contraction movement. After the T-shaped limit rod passes over the limit plate, the limit plate is reset through the connecting assembly. The reset limit plate blocks the reset movement of the T-shaped limit rod, thereby playing a blocking and limiting role after the mounting plates and the pressure plate move away from each other, thereby preventing the reset of the pressure plate after cutting from causing the cut dust-free paper body to be reset and pulled, affecting the subsequent collection and sorting operations.

[0026] S7: After the cutting is completed, the lifting plate is driven to rise and reset through the lifting assembly. During the process of the lifting plate rising and resetting, one end of the T-shaped limit rod on the mounting plate is abutted against the push plate, pushing the T-shaped limit rod to retract downward on the mounting plate. During the process of the T-shaped limit rod retracting, the T-shaped limit rod is no longer abutted against the limit plate, thereby releasing the limit on the mounting plate, so that the mounting plate and the pressure plate can be reset normally. By resetting the mounting plate and the pressure plate, repeated flattening operations in subsequent cutting processes are facilitated.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] The present invention cuts the dust-free paper body through the mutual cooperation of the conveying component, the winding component and the processing component. In the process of cutting, the two groups of mounting plates and the pressure plate are moved away from each other after being subjected to force through transmission. Since the pressure plate abuts against the upper surface of the dust-free paper body, the dust-free paper body that is pressed against and squeezed is flattened through the mutual movement of the pressure plate after being subjected to force, thereby reducing the probability of wrinkles on the dust-free paper body to be cut, and further facilitating a more precise cutting operation of the dust-free paper body.

[0044] The processing assembly includes two groups of mutually symmetrically arranged mounting plates 701 arranged on the circular frame 5, a sliding assembly for slidably connecting the mounting plates 701 is arranged on the circular frame 5, a pressing plate 702 is arranged below the mounting plate 701, a telescopic assembly for telescopically connecting the pressing plate 702 is arranged between the pressing plate 702 and the mounting plate 701, a transmission assembly for assisting the transmission of the pressing plate 702 is arranged between the circular frame 5 and the two groups of pressing plates 702, and a limiting assembly for limiting the mounting plate 701 after transmission is arranged on the circular frame 5;

[0045] It should be noted here that the dust-free paper body 105 is cut through the cooperation of the conveying component, the winding component and the processing component, and during the cutting process, the two sets of mounting plates 701 and the pressure plate 702 are driven to move away from each other through transmission. Since the pressure plate 702 is against the upper surface of the dust-free paper body 105, the pressure plate 702 moves away from each other after being driven, and the dust-free paper body 105 that is pressed against each other is flattened, thereby reducing the probability of wrinkles on the dust-free paper body 105 to be cut, and further facilitating a more precise cutting operation of the dust-free paper body 105.

[0046] Preferably, the transmission assembly includes a transmission plate 1001 fixed to the lower end of the circular frame 5, and the transmission plate 1001 is provided with two groups of symmetrically arranged inclined grooves 1002, and the two groups of inclined grooves 1002 are slidably connected with transmission pins 1003, and one end of the two groups of transmission pins 1003 is respectively fixed to one side of the two groups of pressure plates 702;

[0047] It should be noted here that: in the process of cutting the dust-free paper body 105 by descending the lifting plate 103, as the lifting plate 103 descends, the two groups of pressure plates 702 under the circular frame 5 first abut against the surface of the dust-free paper body 105 and limit the position in the vertical direction, and as the lifting plate 103 and the circular frame 5 continue to descend, the circular frame 5 moves toward the abutted pressure plates 702, and in the process of movement, the two groups of inclined grooves 1002 on the transmission plate 1001 interact with the two groups of transmission pins 1003 respectively, so that the two groups of pressure plates 702 are driven to move under force.

[0048] Preferably, the telescopic assembly includes a plurality of groups of first sleeves 801 fixed to the upper end of the pressing plate 702, each group of the first sleeves 801 is slidably connected with a first slide bar 802, one end of the first slide bar 802 is fixed to the mounting plate 701, and a first spring 803 is sleeved on the outer side of the first sleeve 801, and the two ends of the first spring 803 are respectively connected to the mounting plate 701 and the pressing plate 702;

[0049] It should be noted here that: the first sleeve 801 and the first slide bar 802 facilitate the telescopic connection between the auxiliary pressing plate 702 and the mounting plate 701, and the first spring 803 facilitates the resetting of the pressing plate 702 after the contraction movement.

[0050] Preferably, the sliding assembly includes a plurality of groups of T-shaped rods 901 slidably connected to the circular frame 5, one end of each group of T-shaped rods 901 is fixed to one side of the mounting plate 701, and the outer side of the T-shaped rods 901 is sleeved with mounting springs 902;

[0051] It should be noted here that: by using multiple groups of T-shaped rods 901, it is convenient to guide the installation plate 701 after being subjected to force, and by installing the spring 902, it is convenient to reset the installation plate 701 after movement.

[0052] Preferably, the limiting assembly includes a T-shaped limiting rod 1101 slidably connected to the mounting plate 701, a connecting spring 1102 is sleeved on the outer side of the T-shaped limiting rod 1101, and a limiting plate 1103 is connected to the circular frame 5 through a connecting assembly, and an inclined surface 1104 for resisting and transmitting with the T-shaped limiting rod 1101 is provided on the limiting plate 1103;

[0053] It should be noted here that: in the process of driving the two groups of mounting plates 701 to move away from each other under force, as the mounting plate 701 moves, the T-shaped limit rod 1101 on the mounting plate 701 and the inclined surface 1104 on the limit plate 1103 are offset against each other. During the offset process, the limit plate 1103 is forced to contract. After the T-shaped limit rod 1101 passes over the limit plate 1103, the limit plate 1103 is reset through the connecting component. The reset limit plate 1103 blocks the reset movement of the T-shaped limit rod 1101, thereby playing a blocking and limiting role after the mounting plates 701 and the pressure plate 702 move away from each other.

[0054] Preferably, the connecting assembly includes a fixing frame 1301 fixed to the upper end of the circular frame 5, a plurality of groups of second sleeves 1302 are fixed on the fixing frame 1301, each group of second sleeves 1302 is slidably connected with a second slide bar 1303, one end of the second slide bar 1303 is fixed to the limit plate 1103, a second spring 1304 is sleeved on the outer side of the second sleeve 1302, and the two ends of the second spring 1304 are respectively connected to the limit plate 1103 and the fixing frame 1301, and a push plate 12 for pressing against the end of the T-shaped limit rod 1101 is fixed on the support frame 102;

[0056] Preferably, the lifting assembly includes a connecting plate 201 fixed between the two sets of support frames 102, and a cylinder 202 for lifting and lowering the lifting plate 103 is installed on the connecting plate 201;

[0057] It should be noted here that: the cylinder 202 on the connecting plate 201 can facilitate driving the lifting plate 103 to perform lifting movements.

[0058] Preferably, the winding assembly includes two groups of mounting grooves 401 provided on the machine body 101, a winding roller 402 is provided between the two groups of mounting grooves 401, the winding roller 402 is rotatably connected to the two groups of mounting grooves 401 through a bearing 403, the dust-free paper body 105 is wound on the winding roller 402, and a supporting roller 404 for supporting the conveyed dust-free paper body 105 is provided on the machine body 101;

[0059] It should be noted here that: the reeling roller 402 facilitates the reeling operation of the dust-free paper body 105 , and the mounting groove 401 and the bearing 403 facilitate the auxiliary reeling roller 402 to rotate.

[0060] Preferably, the conveying assembly includes two sets of mounting shafts 301 rotatably connected to the body 101, and conveying rollers 302 are fixed to the two sets of mounting shafts 301. The dust-free paper body 105 passes through between the two sets of conveying rollers 302 and is arranged against each other. A driving motor 303 for driving the mounting shafts 301 is installed on the body 101;

[0061] It should be noted here that: the end of the dust-free paper body 105 rolled on the winding roller 402 is passed through and abutted against the two groups of conveying rollers 302. During the passing process, the support roller 404 is abutted against the inner side of the dust-free paper body 105, and the dust-free paper body 105 is elastically supported to facilitate the subsequent stable and high-quality conveying operation of the dust-free paper body 105. After the dust-free paper body 105 is passed through, the conveying roller 302 on the mounting shaft 301 is driven to rotate by the driving motor 303. Because the two groups of conveying rollers 302 abut against the dust-free paper body 105, the dust-free paper body 105 is driven for conveyance through the abutting friction between the conveying roller 302 and the dust-free paper body 105.

[0062] A high-precision cutting method for dust-free paper comprises the following steps:

[0063] S1: When the mechanical dust-free paper cutter is used to cut the dust-free paper body 105, the end of the dust-free paper body 105 rolled on the winding roller 402 is passed through between the two sets of conveying rollers 302 and abutted against each other. During the passing process, the support roller 404 abuts against the inner side of the dust-free paper body 105, and the dust-free paper body 105 is elastically supported, so as to facilitate the subsequent stable and high-quality conveying operation of the dust-free paper body 105;

[0064] S2: After the dust-free paper body 105 is threaded, the conveying roller 302 on the mounting shaft 301 is driven to rotate by the driving motor 303. Since the two sets of conveying rollers 302 are against the dust-free paper body 105, the dust-free paper body 105 is driven to be conveyed by the friction between the conveying rollers 302 and the dust-free paper body 105;

[0065] S3: After the dust-free paper body 105 is conveyed to a certain length, the lifting plate 103 is driven to move downward by the lifting assembly. During the downward movement of the lifting plate 103, the cutter 104 at the lower end of the lifting plate 103 abuts against the dust-free paper body 105 conveyed to a certain length above the support plate 106, and the dust-free paper body 105 is cut;

[0066] S4: In the process of cutting the dust-free paper body 105 by descending the lifting plate 103, as the lifting plate 103 descends, the two groups of pressing plates 702 below the circular frame 5 first abut against the surface of the dust-free paper body 105 and are limited in the vertical direction. As the lifting plate 103 and the circular frame 5 continue to descend, the circular frame 5 moves toward the abutted pressing plates 702. During the movement, the two groups of inclined grooves 1002 on the transmission plate 1001 interact with the two groups of transmission pins 1003 respectively, so that the two groups of pressing plates 702 are driven to move under force;

[0067] S5: During the movement of the pressing plate 702, the mounting plate 701 is driven to move through the connection of the telescopic assembly. During the movement of the mounting plate 701, the two groups of mounting plates 701 and the pressing plate 702 are forced to move away from each other through the sliding guide of each group of T-bars 901. Since the pressing plate 702 abuts against the upper surface of the dust-free paper body 105, the pressing plate 702 moves away from each other after being forced, and the dust-free paper body 105 that is pressed against each other is flattened through the movement of the pressing plate 702 to reduce the probability of wrinkles on the dust-free paper body 105 to be cut, and further facilitate the dust-free paper body 105 to be cut with higher precision.

[0068] S6: In the process of driving the two groups of mounting plates 701 to move away from each other under force, as the mounting plates 701 move, the T-shaped limit rod 1101 on the mounting plates 701 and the inclined surface 1104 on the limit plate 1103 are abutted against each other. During the abutment process, the limit plate 1103 is forced to contract. After the T-shaped limit rod 1101 passes over the limit plate 1103, the limit plate 1103 is reset through the connecting assembly. The reset limit plate 1103 blocks the reset movement of the T-shaped limit rod 1101, thereby blocking and limiting the mounting plates 701 and the pressing plates 702 after they move away from each other, thereby preventing the reset of the pressing plates 702 after cutting from causing the cut dust-free paper body 105 to be reset and pulled, affecting the subsequent collection and sorting operations.

[0069] S7: After the cutting is completed, the lifting plate 103 is driven to rise and reset through the lifting assembly. During the process of the lifting plate 103 rising and resetting, one end of the T-shaped limit rod 1101 on the mounting plate 701 is abutted against the push plate 12, pushing the T-shaped limit rod 1101 to retract downward on the mounting plate 701. During the retraction of the T-shaped limit rod 1101, the T-shaped limit rod 1101 is no longer abutted against the limit plate 1103, and the limit on the mounting plate 701 is released, so that the mounting plate 701 and the pressing plate 702 can be reset normally. The resetting of the mounting plate 701 and the pressing plate 702 facilitates the repeated flattening operation in the subsequent cutting process.

10. A high-precision cutting method for dust-free paper, which refers to a high-precision cutting device for dust-free paper according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: During the process of cutting the dust-free paper body (105) using a mechanical dust-free paper cutter, the end of the dust-free paper body (105) rolled on the winding roller (402) is passed through between the two sets of conveying rollers (302) and abutted against each other. During the passing process, the support roller (404) abuts against the inner side of the dust-free paper body (105), elastically supporting the dust-free paper body (105), thereby facilitating the subsequent stable and high-quality conveying operation of the dust-free paper body (105); S2: After the dust-free paper body (105) is threaded, the conveying roller (302) on the mounting shaft (301) is driven to rotate by the driving motor (303). Since the two sets of conveying rollers (302) are in contact with the dust-free paper body (105), the dust-free paper body (105) is driven to be conveyed by the friction between the conveying rollers (302) and the dust-free paper body (105); S3: After the dust-free paper body (105) is conveyed to a certain length, the lifting plate (103) is driven to move downward by the lifting assembly. During the downward movement of the lifting plate (103), the cutter (104) at the lower end of the lifting plate (103) is abutted against the dust-free paper body (105) conveyed to a certain length above the support plate (106), thereby cutting the dust-free paper body (105); S4: In the process of cutting the dust-free paper body (105) by descending the lifting plate (103), as the lifting plate (103) descends, the two groups of pressing plates (702) below the circular frame (5) first abut against the surface of the dust-free paper body (105) and are limited in the vertical direction. As the lifting plate (103) and the circular frame (5) continue to descend, the circular frame (5) moves toward the abutted pressing plates (702). During the movement, the two groups of inclined grooves (1002) on the transmission plate (1001) interact with the two groups of transmission pins (1003) respectively, so that the two groups of pressing plates (702) are driven to move under force; S5: During the movement of the pressing plate (702), the connecting action of the telescopic assembly drives the installation plate (701) to move. During the movement of the installation plate (701), the sliding guiding action of each group of T-shaped rods (901) causes the two groups of installation plates (701) and the pressing plate (702) to move away from each other after being subjected to force. Since the pressing plate (702) abuts against the upper surface of the dust-free paper body (105), the dust-free paper body (105) that is pressed against each other and is squeezed is flattened through the movement of the pressing plate (702) to reduce the probability of wrinkles on the dust-free paper body (105) to be cut, further facilitating a more accurate cutting operation of the dust-free paper body (105); S6: In the process of driving the two groups of mounting plates (701) to move away from each other under force, as the mounting plates (701) move, the T-shaped limit rod (1101) on the mounting plates (701) and the inclined surface (1104) on the limit plate (1103) are abutted against each other. During the abutment process, the limit plate (1103) is forced to contract. After the T-shaped limit rod (1101) passes over the limit plate (1103), the limit plate (1103) is reset through the connecting assembly. The reset limit plate (1103) blocks the reset movement of the T-shaped limit rod (1101), thereby blocking and limiting the mounting plates (701) and the pressing plate (702) after they move away from each other, thereby preventing the reset of the pressing plate (702) after cutting from causing the cut dust-free paper body (105) to be reset and pulled, affecting the subsequent collection and sorting operations; S7: After the cutting is completed, the lifting plate (103) is driven to rise and reset through the lifting assembly. During the process of the lifting plate (103) rising and resetting, one end of the T-shaped limit rod (1101) on the mounting plate (701) is abutted against the push plate (12), pushing the T-shaped limit rod (1101) to retract downward on the mounting plate (701). During the retracting movement of the T-shaped limit rod (1101), the T-shaped limit rod (1101) is no longer abutted against the limit plate (1103), releasing the limit on the mounting plate (701), so that the mounting plate (701) and the pressing plate (702) can be reset normally. The reset of the mounting plate (701) and the pressing plate (702) facilitates the repeated flattening operation in the subsequent cutting process.
