Description

Technical Field

[0001] The invention relates to the technical field of slitting machine equipment, in particular to a high-speed slitting machine. Background Art

[0002] High-speed slitting machine is a high-efficiency and high-precision processing equipment that cuts wide raw materials into narrow strips. It is widely used for cutting non-woven fabrics, mica tapes, paper, insulation materials and various film materials. A complete high-speed slitting machine usually includes necessary components such as a frame, a feeding device, a cutting device, a winding device and an electronic control device. Among them, the cutting device is the most important component of the high-speed slitting machine. The cutters used in the cutter device include a group of upper and lower knives and several groups of rolling shear type cutters installed, such as the cutter device of the high-speed slitting machine disclosed in the Chinese patent document with authorization announcement number CN211393286U. There are also knife / anvil matching cutters in which several cutters are arranged on the knife shaft, and then several cutting grooves matching the cutters are correspondingly arranged on the knife anvil shaft, such as the cutter device involved in the high-speed slitting machine disclosed in the Chinese patent document with authorization announcement number CN 207943628U. Among them, the rolling shear type cutter is widely used because of its fast cutting speed, good incision quality and the cutting blade is not easy to be damaged. At present, common high-speed slitting machines generally have an automatic knife arrangement function (that is, a number of cutters and the distance between two adjacent cutters are set on the knife shaft according to the needs of cutting).

DETAILED DESCRIPTION

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] (Example 1) Definition of terms: Knife separation refers to the automatic adjustment of the axial distance between the upper knife and the lower knife in the rolling shear cutter device; The winding core tube refers to a tubular structural member which is detachably arranged on the winding shaft and adapted to the width of the narrow material to be wound after each slitting, and is used for winding the narrow material to be wound after slitting.

[0019] See Figures 1 to 4 and Fig.15 The high-speed slitting machine of this embodiment is mainly composed of a frame 1, a feeding device 2, a winding device 3, a cutting device 4, an electric control device 5, a winding core tube positioning device 6 and a waste recovery device 7.

[0020] The frame 1 serves as the installation base for other components of the high-speed slitting machine of this embodiment. As a specific implementation, in this embodiment, the frame 1 is mainly composed of a left support plate 11, a right support plate 12, a plurality of tie rods 13 for pulling and connecting the left support plate 11 and the right support plate 12, a left cabinet 14 arranged on the left support plate 11, and a right cabinet 15 arranged on the right support plate 12. As a preferred embodiment, a waste outlet 15-1 is provided on the right side of the right cabinet 15; a transparent observation window 15-2 is provided on the front side of the right cabinet 15 for conveniently observing the operating status of the relevant components in the cabinet during operation.

[0021] The feeding device 2 is arranged on the frame 1, and is used to convey the raw materials to be cut to the cutting device 4. The feeding device 2 can adopt the common structure of the existing high-speed slitting machine. As a structural improvement, in this embodiment, the feeding device 2 includes a raw material roll placement mechanism 21, a raw material traction roller 22, a main drive motor 23, and a material receiving platform 24. As a preferred embodiment, the feeding device 2 also includes a laminating material unwinding shaft 25 and a laminating material guide roller 26.

[0022] See also Figure 2 and Figure 4The raw material roll placement mechanism 21 is used to place the raw material roll 101 to be cut. In order to efficiently replace and quickly move the raw material roll 101 into place during production, as an improvement on the structure commonly used in the raw material roll placement mechanism of the prior art, in this embodiment, the raw material roll placement mechanism 21 includes a mounting base plate 21-1 movably arranged on the rear side of the frame 1, two chuck slide rails 21-2 respectively fixedly arranged on the left and right sides of the mounting base plate 21-1, a raw material roll chuck 21-3 slidably arranged on each of the two chuck slide rails 21-2, two chuck translation cylinders 21-4 fixedly arranged on the mounting base plate 21-1 for each driving a raw material roll chuck 21-3 to move left and right on a corresponding chuck slide rail 21-2, and two chuck lifting cylinders 21-4 fixedly arranged on the frame 1 and transmission-connected to the mounting base plate 21-1 so that the two raw material roll chucks 21-3 can move up and down. Obviously, each oil cylinder as a power source can also be replaced by a power output mechanism such as an air cylinder or a motor. The advantages of the raw material roll placement mechanism 21 with the above structure over similar mechanisms in the prior art are: it can quickly and conveniently place raw material rolls 101 to be cut with different lengths and diameters. According to the different lengths of the raw material rolls 101, the two clamp translation oil cylinders 21-4 each drive a raw material roll clamp 21-3 to make a left-right relative movement to automatically adjust the two raw material roll clamps 21-3 to a set spacing, and then the two raw material roll clamps 21-3 are connected to the central through hole of the raw material roll 101 from both sides. At the same time, according to the different diameters of the raw material roll 101, the two raw material roll clamps 21-3 are driven by the two clamp lifting oil cylinders 21-4 to move up and down to adjust the distance between the raw material roll 101 and the ground accordingly and make the raw material roll 101 reach the set position quickly and accurately.

[0023] The material pulling roller 22 is used to pull the material to be cut from the material roll 101 and move it toward the cutting device 4. The material pulling roller 22 adopts a pair of rollers consisting of an active roller 22-1 and a driven roller 22-2; the main drive motor 23 provides rotational power for the active roller 22-1 of the material pulling roller 22, and provides power for the knife shaft rotation drive mechanism of the cutting device 4 (detailed description later).

[0024] See also Figures 5 to 7 The material receiving platform 24 is used to connect the end of the previous raw material roll 101 that is about to be cut with the head end of the newly installed raw material roll 101, so as to achieve continuous cutting of the raw material and improve the cutting efficiency, and solve the technical problems of stopping the machine after cutting a roll of raw material, and then putting the raw material roll again and manually stretching and arranging the end of the raw material roll on the high-speed slitting machine as if it were the first time, which is time-consuming and labor-intensive and reduces the processing efficiency. Figures 5 to 7As an improvement over the prior art, the material receiving platform 24 of this embodiment includes a mounting bracket 24-1 fixedly arranged on each side of the frame 1, a material support platform 24-2 fixedly arranged between the two mounting brackets 24-1 and composed of a plate body with a cutting groove 24-2-1 in the middle, a material pressing plate 24-3 arranged above the material support platform 24-2 and provided with a piece on each side of the cutting groove 24-2-1, and a material pressing plate 24-3 fixedly arranged on the mounting bracket 24-1 and provided with a piece on each side below the two ends of each material pressing plate 24-3. A pressing plate driving cylinder 24-4 is provided for driving the pressing plate 24-3 to move up and down, a transition roller 24-5 and a material transfer adjustment roller 24-6 are rotatably provided between two mounting brackets 24-1 and respectively located at the front and rear sides of the supporting platform 24-2, and a material transfer adjustment roller adjustment mechanism 25-7 is fixedly provided on each of the two mounting brackets 24-1 and is respectively connected to the left and right ends of the material transfer adjustment roller 24-6 for adjusting the upper and lower positions of the left end and / or right end of the material transfer adjustment roller 24-6. Among them, the transition roller 24-5 and the material transfer adjustment roller 24-6 are both passive rotating rollers; the transition roller 24-5 is used to prevent the raw material to be cut pulled out from the raw material roll 101 from rubbing against the two pressing plates 24-3 when passing through the material receiving platform 24, causing raw material defects, and the material transfer adjustment roller 24-6 is used to adjust the flatness of the raw material to be cut pulled out from the raw material roll, especially the wide-width raw material, under the drive of the two material transfer adjustment roller adjustment mechanisms 24-7, so as to achieve high-quality cutting. Figure 7As shown, as a specific implementation method, the feed adjustment roller adjustment mechanism 24-7 is mainly composed of a support frame 24-7-1 fixed on the mounting bracket 24-1, two guide rods 24-7-2 fixedly arranged in the support frame 24-7-1 in the upper and lower directions, a driving block 24-7-3 which is movably connected to the two guide rods 24-7-2 and is connected to one end of the feed adjustment roller 24-6 and can support the rotation of the feed adjustment roller 24-6, an adjusting screw 24-7-4 rotatably arranged in the support frame 24-7-1 and threadedly cooperated with the threaded hole in the driving block 24-7-3 to enable the driving block 24-7-3 to move up and down, and an adjusting handle 24-7-5 fixedly arranged at the upper end of the adjusting screw 24-7-4 for easy operation. During operation, when the flatness of the raw material to be cut passing under the material transfer adjustment roller 24-6 is not good, the material transfer adjustment roller adjustment mechanism 24-7 is operated to make one or both ends of the material transfer adjustment roller 24-6 move up and down to adjust the flatness of the raw material to be cut to the optimal state, so as to achieve high-quality cutting. During the processing, the method of using the material receiving platform 24 to receive the material is as follows: overlap the end of the previous raw material roll 101 that is about to be cut with the head end of the newly installed raw material roll 101, drive the two pressing plates 24-3 to press down the overlapping part front and back through the pressing plate driving cylinder 24-4, then use a tool such as a utility knife to cut the overlapping part relying on the cutting groove 24-2-1, and throw away the cut edge material. At this time, the end of the previous raw material roll 101 and the head end of the next raw material roll 101 are aligned, and then use adhesive materials such as transparent glue to connect the two from above. If necessary, they can be connected on both sides to enhance the firmness of the connection, and then drive the two pressing plates 24-3 to lift up through the pressing plate driving cylinder 24-4, and then continue to implement the slitting operation. It can be seen that by setting the material receiving platform 24, the trouble of re-loading on the high-speed slitting machine when loading a new raw material roll 101 can be avoided, and the work efficiency can be improved.

[0025] As a preferred method, in order to solve the technical problem that two different raw materials need to be bonded and then slit during the actual processing process, but the existing high-speed slitting machines are difficult to meet this requirement, the feeding device 2 of this embodiment also includes a bonding material unwinding shaft 25 and a bonding material guide roller 26 which are passively rotatably arranged on the frame 1 and located above the material receiving platform 24, wherein the bonding material unwinding shaft 25 is used to place the bonding material roll 102 with adhesiveness on one side; the bonding material guide roller 26 is used to guide the bonding material output from the bonding material roll 102 to move toward the raw material traction roller 22; the bonding material to be slit output from the raw material roll 101 and the bonding material output from the bonding material roll 102 are automatically bonded after passing through the raw material traction roller 22 (counter-roller), and then move to the cutting device 4, and the cutting device 4 cuts the bonded materials to be slit, as shown in FIG. Fig.15 shown.

The winding device 3 can adopt the common structure of the existing high-speed slitting machine. As a structural improvement implementation method, in this embodiment, the winding device 3 includes a winding shaft 31 arranged on the frame 1, a winding shaft support mechanism 32 that is movably matched with one end of the winding shaft 31 to facilitate the unloading of the narrow material roll 103 after cutting, a winding motor 33 for driving the winding shaft 31 to rotate, a winding roller mechanism 34 for flattening and pressing the narrow material after cutting to ensure the quality of winding, and a winding guide roller 35 for guiding the movement of the narrow material after cutting. A winding core tube (not shown in the figure, and those skilled in the art are familiar with it) is arranged on the winding shaft 31, and the number of the winding core tubes is set accordingly according to the number of rolls to be rolled. Obviously, one reel can be provided. In this embodiment, the reel 31 is provided with two reel arms, an upper reel 31-1 and a lower reel 31-2.

[0027] See also Figures 8 to 14The cutting device 4 is mainly composed of a lower knife shaft 41, an upper knife shaft 42, a knife shaft rotation driving mechanism 43, a lower knife 44, an upper knife 45, a knife magazine 46, an automatic knife arrangement mechanism 47, and an upper and lower knife separation and separation mechanism 48.

[0028] The lower blade shaft 41 and the upper blade shaft 42 can adopt the common structure of the blade shaft adopted by the existing high-speed slitting machine. The lower blade shaft 41 and the upper blade shaft 42 are rotatably arranged on the frame 1. As an improvement on the prior art, the lower blade shaft 41 of this embodiment adopts a key-type air-expanding shaft with a plurality of radially embedded and evenly distributed rubber strips. Specifically, the lower blade shaft 41 includes an air-expanding shaft body 41-1, four rubber strips 41-2 that are radially embedded and evenly distributed and axially arranged on the shaft body 41-1, and an air nozzle 41-3 for ventilation arranged on one side of the shaft body 41-1. The structure of the upper blade shaft 42 is the same as that of the lower blade shaft 41. The lower knife shaft 41 and the upper knife shaft 42 adopt the aforementioned structure, so that after the lower knife 44 and the upper knife 45 respectively installed on the lower knife shaft 41 and the upper knife shaft 42 are arranged in place, the lower knife 44 and the upper knife 45 can be installed and fastened on the lower knife shaft 41 and the upper knife shaft 42 respectively only by expanding the lower knife shaft 41 and the upper knife shaft 42 through air intake, without the need to manually tighten the fastening screws provided on the lower knife 44 and the upper knife 45 to fasten them to the corresponding knife shafts as in the prior art, thereby saving manpower and improving work efficiency.

[0029] The knife shaft rotation drive mechanism 43 is used to drive the lower knife shaft 41 and the upper knife shaft 42 to rotate so as to drive the lower knife 44 and the upper knife 45 to rotate accordingly, so as to realize the rolling shear type slitting of the material to be slit. As a specific implementation method, the knife shaft rotation drive mechanism 43 includes a power input gear 43-1 arranged at one end of the lower knife shaft 41, a first transmission gear 43-2 arranged on the lower knife shaft 41 and on the same side as the power input gear 43-1, and a second transmission gear 43-3 arranged on the upper knife shaft 42 and capable of engaging or disengaging with the first transmission gear 43-2; the power of the knife shaft rotation drive mechanism 43 comes from the aforementioned main drive motor 23; the knife shaft rotation drive mechanism 43 is connected to the main drive motor 23 by its power input gear 43-1.

[0030] The lower knife 44 and the upper knife 45 are circular knives (also known as disc knives in the industry); each lower knife 44 cooperates with a corresponding upper knife 45 to form a rolling shear type knife group.

[0031] The tool magazine 46 is used to store all the cutting knives before the knife arrangement and the cutting knives that do not participate in the cutting when working after the knife arrangement (the cutting knives in this embodiment refer to the lower knife 44 and the upper knife 45). The tool magazine 46 is composed of a space surrounded by a tool magazine mounting plate 46-1, a mounting connecting rod 46-2 and the middle and upper part of the right support plate 12 of the frame 1. The tool magazine mounting plate 46-1 is fixedly connected to the right support plate 12 of the frame 1 through a plurality of mounting connecting rods 46-2 and is arranged on the right side of the right support plate 12; a clearance hole that passes through the left and right directions is opened in the middle and upper part of the right support plate 12, and the right sides of the lower knife shaft 41 and the upper knife shaft 42 extend to the right into the tool magazine 46 through the clearance hole of the right support plate 12, and the right end of the lower knife shaft 41 is rotatably arranged on the tool magazine mounting plate 46-1. The lower knife 44 and the upper knife 45 are arranged in sequence in the tool magazine 46 in a staggered manner. By setting up a tool magazine 46, before each slitting work, a corresponding number of cutters can be called out from the tool magazine 46 according to the needs of this slitting, and the remaining cutters are retained in the tool magazine 46, thereby effectively solving the technical problem that the number of cutters set on the knife shaft of the existing high-speed slitting machine are all temporarily installed and arranged in parallel according to the needs of this slitting. When the number of cutters required for the next slitting is different, it is necessary to manually pull out the knife shaft, and then add or remove a certain number of cutters on the knife shaft, which brings inconvenience in use, affects the use efficiency and poses certain risks to the operator.

[0032] The automatic tool arrangement mechanism 47 is used to automatically call out a set number of lower knives 44 and upper knives 45 from the lower knife 44 and upper knife 45 groups stored on the lower knife shaft 41 and the upper knife shaft 42 extending into the tool magazine 46 according to the slitting needs, and arrange them on the lower knife shaft 41 and the upper knife shaft 42 according to the set positions and intervals. As an improvement on the prior art, in this embodiment, the automatic tool arrangement mechanism 47 includes an electric cylinder mounting beam 47-1 fixed on the frame 1, an electric cylinder 47-2 fixed on the electric cylinder mounting beam 47-1, and an automatic clamp 47-3 driven by the electric cylinder 47-2 to move left and right. As a preferred embodiment, the automatic tool arrangement mechanism 47 also includes a tool arrangement limit position sensor 47-4 provided on each of the left and right sides of the electric cylinder 47-2 for limiting the left and right movement of the automatic clamp 47-3. The electric cylinder 47-2 (also called a slide module or a linear module) is a commercially available part, and the tool arrangement limit position sensor 47-4 is a commercially available contact sensor. As shown in FIG. Fig.14 As shown, the automatic clamp 47-3 includes a commercially available pneumatic finger 47-3-1, two cutter clamps 47-3-2 fixedly mounted on the pneumatic finger 47-3-1, and two sensor mounting arms 47-3-3, and a knife search sensor 47-3-4 mounted on the two sensor mounting arms 47-3-3. The knife search sensor 47-3-4 preferably adopts a through-beam photoelectric sensor. Two sets of automatic knife arrangement mechanisms 47 with the same structure are provided, and the two sets of automatic knife arrangement mechanisms 47 are arranged oppositely in the upper and lower parts, respectively, for automatically arranging the upper knife 45 and the lower knife 44 on the upper knife shaft 42 and the lower knife shaft 41.

[0033] The working process of the automatic knife arrangement mechanism 47 is explained by taking the automatic arrangement of the lower knife 44 on the lower knife shaft 41 as an example: under the control of the electric control device 5, the automatic clamp 47-3 moves to the right side of the lower knife shaft 41 in the knife magazine 46 with its two knife clamps 47-3-2 in an open state, and when the knife search sensor 47-3-4 senses the first lower knife 44 in the knife magazine 46, the two knife clamps 47-3-2 clamp the lower knife 44, and then the automatic clamp 47-3 drives the lower knife 44 to move to the left on the lower knife shaft 41 to a set position, and then the two knife clamps 47-3-2 are released to release the lower knife 44, and then the automatic clamp 47-3 continues to arrange the subsequent lower knives 44 to the set position as described above. The arrangement process of the upper knife 45 is similar. As can be seen from the above, the automatic knife arrangement mechanism 47 of this embodiment can quickly and accurately arrange the knives on the knife shaft, which is conducive to improving work efficiency and slitting quality.

[0034] The upper and lower knife separation and separation mechanism 48 is used to drive the upper knife 45 and the lower knife 44 to separate so that the material to be cut can pass through, and the upper knife 45 and the lower knife 44 can be matched for cutting, and the axial distance between the upper knife 45 and the lower knife 44 of the same knife group is adjusted. In this embodiment, as a specific implementation method, the upper and lower knife separation and separation mechanism 48 is mainly composed of an upper knife shaft rocking shaft 48-1, an upper knife shaft support arm 48-2, an upper knife shaft clutch drive arm 48-3, an upper knife shaft clutch drive cylinder 48-4, a limit block 48-5, a limit member 48-6, a knife separation drive assembly 48-7, and a knife separation stroke limit assembly 48-8.

[0035] An upper knife shaft support arm 48-2 is fixedly provided on each of the left and right sides of the upper knife shaft rocking shaft 48-1. The two ends of the upper knife shaft 42 are respectively connected to an upper knife shaft support arm 48-2 and can rotate relying on the two upper knife shaft support arms 48-2; the upper knife shaft clutch drive arm 48-3 is fixedly provided at the right end of the upper knife shaft rocking shaft 48-1 and is located on the right side of the tool magazine mounting plate 46-1 of the tool magazine 46; the upper knife shaft clutch drive cylinder 48-4 is fixedly provided on the tool magazine mounting plate 46-1 and is transmission-connected to the upper knife shaft clutch drive arm 48-3; the limit block 48-5 is on the upper One and two limit blocks 48-5 are fixedly arranged on each of the left and right sides of the tool shaft rocking shaft 48-1 and are located on the outside of the two upper tool shaft support arms 48-2; the limit piece 48-6 is matched with the limit block 48-5 to limit the moving stroke of the upper tool shaft 42, and each limit block 48-5 is equipped with two limit pieces 48-6 arranged in an upper and lower manner, of which the two limit pieces 48-6 located on the left are fixed on the right side surface of the left support plate 11 of the frame 1, and the two limit pieces 48-6 located on the right are fixed on the left side surface of the tool magazine mounting plate 46-1. The knife-cutting drive assembly 48-7 is mainly composed of a knife-cutting drive motor 48-7-1, a coupling 48-7-2 and a connecting flange 48-7-3. The knife-cutting drive motor 48-7-1 is connected to the left end of the upper knife shaft rocking shaft 48-1 through the coupling 48-7-2. The knife-cutting drive motor 48-7-1 and the coupling 48-7-2 are fixed on the left support plate 11 of the frame 1 through the connecting flange 48-7-3. The knife-cutting stroke limit assembly 48-8 is used to limit the knife-cutting stroke, such as Fig.11 As shown, the tool travel limit assembly 48-8 is mainly composed of a detection plate 48-8-1, a sensor support 48-8-2, and a photoelectric sensor 48-8-3. Two photoelectric sensors 48-8-3 are provided on the sensor support 48-8-2, and the sensor support 48-8-2 is fixedly arranged on the right side of the tool magazine mounting plate 46-1. One end of the detection plate 48-8-1 is fixedly connected to the right end of the upper tool shaft shaking shaft 48-1, and the other end of the detection plate 48-8-1 is movably matched with the two photoelectric sensors 48-8-3. Preferably, the tool travel limit assembly 48-8 also includes a retractable detection plate support 48-8-4 for preventing the detection plate 48-8-1 from deforming. The two ends of the detection plate support 48-8-4 are respectively fixedly connected to the detection plate 48-8-1 and the tool magazine mounting plate 46-1.

[0036] The working principle and process of the upper and lower knife separation and separation mechanism 48 are briefly described as follows: when the material to be cut needs to pass through the cutting knife device 4 for feeding, the piston rod of the upper knife shaft clutch driving cylinder 48-4 retracts, and the power of the upper knife shaft clutch driving cylinder 48-4 is transmitted in sequence through the upper knife shaft clutch driving arm 48-3, the upper knife shaft rocking shaft 48-1, and the two upper knife shaft support arms 48-2 to make the upper knife shaft 42 move upward, thereby separating the upper knife 45 from the lower knife 44 so that there is a gap for feeding between the two; when the feeding is completed, the piston rod of the upper knife shaft clutch driving cylinder 48-4 extends out, so that the upper knife 45 and the lower knife 44 are aligned and close to the set position; during the movement of the upper knife shaft 42, the limit block 48-5 and the limit member 48-6 limit the extreme position of the movement of the upper knife shaft 42. When the upper knife 45 and the lower knife 44 are aligned, the knife drive motor 48-7-1 of the knife drive assembly 48-7 is started to make the upper knife shaft shaking shaft 48-1 move slightly to the right in a straight line, thereby driving the upper knife shaft 42 to move to the right, so that the axial spacing between the upper knife 45 and the lower knife 44 of the same group after each row of knives on the upper knife shaft 42 is adjusted to the optimal state. During the knife separation process, the knife separation stroke limit assembly 48-8 is used to limit the knife separation stroke. When the photoelectric sensor 48-8-3 of the knife separation stroke limit assembly 48-8 sends a signal that the adjustment is in place, the knife drive motor 48-7-1 stops running. At this time, the axial spacing between the upper knife 45 and the lower knife 44 of each knife group used for cutting has been adjusted to the set optimal spacing.

When in use, according to the total number of winding core tubes arranged on the upper winding shaft 31-1 and the lower winding shaft 31-2 of the winding device 3 (that is, the total number of narrow material rolls 103 after slitting), a corresponding number of one-word laser modules 63 are manually slid to the right from the left side of the slide rail 61, and each one-word laser module 63 emits a linear visible laser beam; the operation method for accurately positioning each winding core tube is: first align the visible laser beam emitted by the first one-word laser module 63 on the left side that is moved out with the left side of the first upper knife 45 on the leftmost side of the upper knife shaft 42, and then move the first winding core tube on the left side of the upper winding shaft 31-1 so that the left end of the winding core tube As close as possible to the visible laser beam emitted by the first one-word laser module 63, the left side of the winding core tube is accurately aligned with the left side of the first upper knife 45; then the visible laser beam emitted by the second one-word laser module 63 is aligned with the left side of the first lower knife 44 on the lower knife shaft 43, and then the first winding core tube on the left side of the lower winding shaft 31-2 is moved, so that the left end of the winding core tube is as close as possible to the visible laser beam emitted by the second one-word laser module 63, so that the left side of the winding core tube is accurately aligned with the left side of the first lower knife 44; repeat this until each winding core tube is accurately positioned. In this embodiment, the winding core tube positioning device 6 is set as a preferred method.
