Description

TECHNICAL FIELD

[0001] The utility model relates to a slitting machine, in particular to a coiled material slitting machine. BACKGROUND

[0002] Surface coating technology is used to attach the veneer material to the substrate surface, which can not only protect the substrate but also beautify the appearance. The substrate is usually a wooden strip, medium density board, wood-plastic, plastic steel, aluminum profile and the like, and the veneer material is usually CPL, PET, PVC, composite aluminum film and the like. The veneer material is a wide roll when it leaves the factory, which needs to be cut into a narrow roll matching the size of the substrate by a slitting machine before being attached.

[0003] The patent application for invention with publication number CN119283117A discloses a slitting machine. When in use, the diaphragm roll is placed on the fixed frame and clamped, and after the diaphragm starts to unroll, the diaphragm on the diaphragm roll is guided by the guide roller, so that the diaphragm is in contact with the upper knife blade to realize the cutting of the diaphragm by the upper knife blade. Meanwhile, a winding roller needs to be arranged behind the rack, and the number of winding rollers is the same as the number of cut diaphragm rolls. The diaphragm is unrolled in front of the rack, cut by the upper knife blade, and wound in the rear of the rack to complete the cutting of the diaphragm roll by unrolling and winding at the same time.

[0004] However, when the diaphragm roll is cut by the slitting machine, the diaphragm roll needs to be continuously unrolled first, and continuously wound behind the rack until the unrolling is completed to realize the complete cutting of the diaphragm roll, which takes a long time. When the width of the cutting is different, the position of the upper knife blade needs to be adjusted repeatedly to make the distance between the adjacent two upper knife blades meet the width requirement of the diaphragm.

DETAILED DESCRIPTION

[0035] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are merely intended to illustrate and explain the present application, and do not constitute a limitation on the present application.

[0036] The orientation words or positional relationships such as "upper", "lower", "left", "right", "front", "back" and the like described in the embodiments are based on the orientation relationship in the drawings of the present application specification Figure 1 、 Figure 3 , 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 must have a specific orientation, a specific orientation structure and operation, and therefore cannot be understood as a limitation on the content protected by the present application.

[0037] As shown in Figures 1-9 , the present embodiment comprises a control box 1, a frame 2, a material shaft, a cutting mechanism 4, a first driving member and a second driving member. The first driving member and the second driving member are used to drive the cutting mechanism 4 to move, so as to perform segmented cutting of different widths on the whole roll of material on the material shaft.

[0038] I. Control box 1, material shaft;

[0039] In the present embodiment, the material shaft adopts an existing air expansion shaft 3, and the specific structure and working principle of the air expansion shaft 3 will not be described in detail in the present embodiment. The air expansion shaft 3 is rotatably arranged on the frame 2. Specifically, Figure 4As shown in the figure, the air inflation shaft 3 is rotatably connected with the frame 2 through the bearing 5, the air inflation shaft 3 is fixedly sleeved in the inner ring of the bearing 5, and the outer ring of the bearing 5 is fixedly sleeved with the frame 2. As shown in the figure Figure 1 , 4 As shown in the figure, the driving of the air inflation shaft 3 is realized through the reduction motor 6, the chain wheels 7 and the chain 8 arranged in the shell 33. The chain wheels 7 are provided with two, one is fixedly arranged at the output end of the reduction motor 6 and the left end of the air inflation shaft 3, and the chain 8 is sleeved on the two chain wheels 7. During work, the reduction motor 6 rotates, the chain wheel 7 fixedly connected with the reduction motor 6 rotates, and then the chain wheel 7 fixedly connected with the air inflation shaft 3 rotates through the chain 8, so as to realize the rotation of the air inflation shaft 3.

[0040] Since the air inflation shaft 3 is made of metal material, if the cutting mechanism 4 cuts to the innermost layer of the roll material, it will contact the air inflation shaft 3, causing the cutting mechanism 4 to be damaged. Therefore, the protective sleeve is covered on the outer contour of the air inflation shaft 3 in the embodiment, as shown in the figure Figure 9 The protective sleeve includes a plurality of arc-shaped pieces 9, the length of each arc-shaped piece 9 is equal to the length of the air inflation shaft 3, the bending radius of the arc-shaped piece 9 is the same as the radius of the outer contour of the air inflation shaft 3, the plurality of arc-shaped pieces 9 are sequentially arranged along the circumference of the air inflation shaft 3, and a small gap is left between the adjacent two arc-shaped pieces 9. In the embodiment, the arc-shaped pieces 9 are adhered on the air inflation shaft 3 by glue. The arc-shaped pieces 9 are made of PVC material, which can protect the air inflation shaft 3 and the cutting mechanism 4 from being damaged. When the cutting mechanism 4 contacts the arc-shaped piece 9 during cutting, it represents that the cutting of the whole roll of roll material is completed. After multiple uses, when there are many cutting marks on the arc-shaped piece 9, it can be replaced, which is more convenient and economical.

[0041] Further, as shown in the figure Figure 1 , 4 The feeding end of the material shaft is detachably provided with a material shaft fixing seat 10, and the feeding end here refers to the right end of the material shaft. The material shaft is rotatably connected with the material shaft fixing seat 10. The material shaft fixing seat 10 is a cubic block structure, and a mounting hole is formed on the material shaft fixing seat 10. The right end of the air inflation shaft 3 penetrates through the material shaft fixing seat 10 and is rotatably connected through the bearing 5, that is, the bearing 5 is fixedly sleeved in the mounting hole, and the right end of the air inflation shaft 3 is fixedly sleeved in the inner ring of the bearing 5, so as to realize the rotatable connection. As shown in the figure Figure 3 The material shaft fixing seat 10 is threadedly connected with a jack 11, the axial direction of the jack 11 extends along the radial direction of the air inflation shaft 3, the jack 11 penetrates through the material shaft fixing seat 10 and abuts against the air inflation shaft 3, so as to tightly press the air inflation shaft 3. When it is needed to place the roll material, the jack 11 is screwed to separate the jack 11 from the air inflation shaft 3, at this time, the material shaft fixing seat 10 can be bent to the right, and then the roll material can be sleeved on the air inflation shaft 3 from the right end of the air inflation shaft 3.

[0042] The material shaft fixing seat 10 is connected with the rack 2 through a support plate 12, the top end of the support plate 12 is fixedly connected with the material shaft fixing seat 10, and the bottom end of the support plate 12 is hingedly arranged on the rack 2. The specific mode of the hinge is that a rotating shaft 13 is fixedly arranged at the bottom end of the support plate 12, the rack 2 and the rotating shaft 13 are hingedly connected through a hinge shaft 14, and the support plate 12 can rotate with the hinge shaft 14 as the rotation center.

[0043] In order to improve the embodiment, a buffer block 15 is fixedly arranged on the side of the material shaft fixing seat 10 away from the material shaft (i.e. the right end surface of the material shaft fixing seat 10), the buffer block 15 is made of rubber or polyurethane material, and the buffer block 15 has the following effect: when the material shaft fixing seat 10 is opened to the right, the buffer block 15 first contacts the ground, thereby buffering and preventing the impact force between the material shaft fixing seat 10 and the ground from being too large. A handle 16 is fixedly arranged at the top end of the material shaft fixing seat 10, so that the material shaft fixing seat 10 can be manually opened to the right.

[0044] II. The cutting mechanism 4;

[0045] As shown in Figure 1 , 7 , the cutting mechanism 4 includes a saw blade 401 and a power member for driving the saw blade 401 to rotate, the rotation axis of the cutting mechanism 4 is parallel to the rotation axis of the material shaft, i.e. the rotation axis of the saw blade 401 is parallel to the rotation axis of the air inflation shaft 3, and the rotation axis is along the left-right direction. As shown in Figure 3 , 5 , the power member is arranged in the first housing 411. The power member includes a motor 402, a first pulley 403 fixedly connected with the output end of the motor 402, a saw shaft seat 404, and a second pulley 405 fixedly connected with the saw shaft seat 404. The saw shaft seat 404 is a prior art. The first pulley 403 and the second pulley 405 are driven through a V-belt 406, and the structure of the V-belt 406 and the matching relationship with the first pulley 403 and the second pulley 405 are prior arts. The end of the saw shaft seat 404 away from the second pulley 405 (i.e. the right end of the saw shaft seat 404) is fixedly connected with the saw blade 401, and the motor 402 is electrically connected with the servo controller in the control box 1. When working, the motor 402 is started to drive the first pulley 403 to rotate, the second pulley 405 is driven to rotate through the V-belt 406, so that the saw blade 401 rotates. If the motor 402 directly drives the saw blade 401 to rotate, a larger motor diameter is required, at this time the effective diameter of the sawing will be reduced, and in the embodiment, the saw shaft seat 404 is arranged between the motor 402 and the saw blade 401, the volume of the saw shaft seat 404 is smaller than that of the motor 402, so that the stroke can be increased.

[0046] Further, as shown in Figure 3As shown, the cutting mechanism 4 further comprises a saw blade guard 407 arranged above the saw blade 401 to block the splinters from flying, and to prevent the operator from being injured by the saw blade 401 when the saw blade 401 rotates at high speed. Figure 7 As shown, a linear laser 408 is fixed on the saw blade guard 407 for positioning and calibration, to ensure that the saw blade 401 is accurately aligned with the position to be cut, so as to perform more accurate cutting. The saw blade guard 407 and the linear laser 408 are prior art.

[0047] As shown, Figure 7 As shown, a waste collecting hopper 409 is arranged at the bottom of the saw blade guard 407 corresponding to the position of the saw blade 401, and a dust suction port 410 is arranged on the waste collecting hopper 409 for connecting with a dust suction pipeline.

[0048] The cutting mechanism 4 is slidingly arranged on the rack 2 by the first driving member and the second driving member.

[0049] III. The first driving member;

[0050] The first driving member drives the cutting mechanism 4 to move along the axial direction of the material shaft (i.e. left and right directions).

[0051] As shown, Figure 3 , 6 As shown, the first driving member comprises a first servo motor 17, a first synchronous pulley 18, a first synchronous belt 19, a first lead screw 20 and a first limiting part; the first servo motor 17, the first synchronous pulley 18 and the first synchronous belt 19 are located in the second housing 34.

[0052] The axial direction of the first lead screw 20 is parallel to the axial direction of the material shaft, and the first lead screw 20 is rotatably arranged on the rack 2 by a first lead screw seat, and the structure of the first lead screw 20 and the first lead screw seat is prior art. As shown, Figure 6 As shown, two first synchronous pulleys 18 are arranged, one is fixed on the output end of the first servo motor 17, and the other is fixed on the right end of the first lead screw 20, and the first synchronous belt 19 is sleeved on the two first synchronous pulleys 18.

[0053] As shown, Figure 3 As shown, the first limiting part comprises a first guide rail 21 and a first sliding block slidingly arranged on the first guide rail 21, and the first guide rail 21 is fixed on the rack 2 and parallel to the axial direction of the material shaft. In this embodiment, two first guide rails 21 are arranged, and the first lead screw 20 is located between the two first guide rails 21, and one first sliding block is slidingly sleeved on each first guide rail 21, and the first sliding block is fixedly connected with the cutting mechanism 4, that is, the two first sliding blocks are fixedly connected with the bottom of the first housing 411.

[0054] The cutting mechanism 4 is threadedly connected with the first screw rod 20. Specifically, a screw nut is threadedly connected with the first screw rod 20, and the screw nut is fixedly connected with the bottom of the first shell 411. When the first screw rod 20 rotates, the screw nut and the first shell 411 have a tendency to rotate with the first screw rod 20, but the screw nut and the first shell 411 cannot rotate due to the restriction of the first guide rail 21 and the first sliding block. At this time, under the cooperation of threads, the screw nut and the first shell 411 slide linearly in the left and right directions. The first driving member can move the cutting structure to a position to be cut.

[0055] To perfect the embodiment, as shown in Figure 6 , a drag chain 22 is arranged on the rack 2. One end of the drag chain 22 is fixedly connected with the rack 2, and the other end is fixedly connected with the cutting mechanism 4 and moves leftward and rightward with the cutting mechanism 4. The drag chain 22 can freely stretch and bend when the cutting mechanism 4 moves, thereby protecting the cable. The structure of the drag chain 22 is a prior art. Figure 7 、 8 To protect the first guide rail 21 and the first screw rod 20, an organ type guide rail protective cover 35 is arranged on each of the left and right sides of the first shell 411. Considering the shielding relationship, Figure 7 , the organ type guide rail protective cover 35 is shown by a dashed line. When the cutting mechanism 4 moves rightward, the left organ type guide rail protective cover 35 is stretched, and the right organ type guide rail protective cover 35 is compressed, thereby preventing dust and cutting debris from entering the first screw rod 20 and the first guide rail 21. Figure 3 As shown in , a proximity switch 23 is arranged on the first guide rail 21 and is used to control the stroke of the cutting mechanism 4. The drag chain 22, the organ type guide rail protective cover 35, and the proximity switch 23 are prior arts.

[0056] Four, a second driving member;

[0057] The second driving member drives the cutting mechanism 4 to move in the direction of approaching or moving away from the material shaft (i.e., the front and back directions).

[0058] As shown in Figure 3 、 6 , 7, the second driving member includes a second servo motor 24, a second synchronous wheel 25, a second synchronous belt 26, a second screw rod 27, and a second limiting part. The second servo motor 24, the second synchronous wheel 25, and the second synchronous belt 26 are located in a third shell 28.

[0059] The second screw rod 27 is arranged on the rack 2 in the axial direction perpendicular to the axial direction of the material shaft and is rotatably arranged on the second screw rod seat. The second synchronous wheel 25 is provided with two synchronous wheels, one of which is fixedly connected with the output end of the second servo motor 24 and the other of which is fixedly connected with the rear end of the second screw rod 27. The second synchronous belt 26 is threadedly connected with the two second synchronous wheels 25.

[0060] As shown in Figure 3 ,6 As shown, the second limiting part comprises a second guide rail 29 and a second sliding block 30 slidingly arranged on the second guide rail 29, the second guide rail 29 is fixedly arranged on the rack 2 and perpendicular to the axial direction of the material shaft, that is, the second lead screw 27 and the second guide rail 29 both extend along the front and back directions. In this embodiment, two second guide rails 29 are arranged, and the second lead screw 27 is located between the two second guide rails 29. One second sliding block 30 is slidingly sleeved on each second guide rail 29, and the second sliding block 30 is fixedly connected with the cutting mechanism 4. Specifically, the second driving part is arranged between the cutting mechanism 4 and the first driving part, as shown in Figure 1 、 6 As shown, the second sliding block 30 is fixedly connected with the bottom end of the first shell 411, and the bottom ends of the two second guide rails 29 are fixedly connected with a base plate 31, and the bottom of the base plate 31 is fixedly connected with the first sliding block and the lead screw nut in the first driving part. The concertina guide rail protective cover 35 in the first driving part is fixedly connected with the base plate 31.

[0061] The cutting mechanism 4 is threadedly sleeved with the second lead screw 27. Specifically, a lead screw nut is also threadedly sleeved on the second lead screw 27, and the lead screw nut is fixedly connected with the bottom of the first shell 411. When the second lead screw 27 rotates, the lead screw nut and the first shell 411 have a tendency to rotate with the second lead screw 27, but due to the limitation of the second guide rail 29 and the second sliding block 30, the lead screw nut and the first shell 411 cannot rotate with the second lead screw 27. At this time, under the thread cooperation, the lead screw nut and the first shell 411 slide linearly along the front and back directions. The second driving part can make the cutting structure feed towards or away from the gas expansion shaft 3.

[0062] The control box 1 and the first driving part, and the control box 1 and the second driving part are electrically connected, that is, the first servo motor 17 and the servo controller in the control box 1, and the second servo motor 24 and the servo controller in the control box 1 are electrically connected. The control box 1 is also provided with a PLC, and the PLC is electrically connected with the servo controller; as shown in Figure 1 The control box 1 is also provided with an operation screen 32 for controlling the cutting times and cutting lengths of the cutting mechanism 4, and the operation screen 32 is electrically connected with the PLC inside the control box 1. The left and right sliding, forward feeding or backward retreating of the cutting mechanism 4 are controlled through the operation screen 32, so as to realize the segmented cutting of the coiled material on the gas expansion shaft 3. The structure of the control box 1 and the internal circuit connection relationship are prior art, which will not be described in detail in this embodiment.

[0063] As shown in Figure 1 The first shell 411 and the rack 2 are also provided with a drag chain 22. In addition, in order to protect the second guide rail 29 and the second lead screw 27, the first shell 411 and the third shell 28 are also fixedly connected with a concertina guide rail protective cover, which can prevent dust and cutting debris from entering the second lead screw 27 and the second guide rail 29. The concertina guide rail protective cover is not shown in the figure.

[0064] When the embodiment is used, the whole roll of the material is sleeved on the air inflation shaft 3, the width of the material to be obtained and the number of cutting are selected by the operation screen 32, the cutting is started, the first driving member drives the cutting mechanism 4 to move to the right to the position to be cut, then the second driving member drives the cutting mechanism 4 to feed forward, the saw blade 401 rotates continuously during the feeding process, and the material also rotates continuously with the air inflation shaft 3, the cutting is started when the saw blade 401 contacts the material. With the rotation of the material, the saw blade 401 cuts the material for one turn until the saw blade 401 cuts to the innermost layer of the material and contacts the protective sleeve, and the material is cut completely. After the first cutting is completed, the second driving member drives the cutting mechanism 4 to retreat backward, then the first driving member drives the cutting mechanism 4 to move to the left to the next position to be cut, and the cutting is realized by feeding forward of the second driving member to drive the cutting mechanism 4, so as to reciprocate, and finally the whole roll of the material is cut into multiple rolls of the material with different widths. Finally, the material shaft fixing seat 10 is opened, and the multiple rolls of the material are taken out.

[0065] The embodiment directly cuts the whole roll of the material, and the whole roll state is maintained before and after the cutting, without the need of unwinding, cutting and rewinding, so that the cutting time is effectively shortened and the operation efficiency is improved. The embodiment realizes the multi-section cutting of the whole roll of the material through automatic operation, which is more time-saving and labor-saving.

[0066] It should be noted that the above only describes the preferred embodiments of the present application, and is not used to limit the present application, although the present application is described in detail with reference to the above embodiments, and for those skilled in the art, the technical solutions recorded in the above embodiments can be modified, or some technical features can be replaced.
