Description

Technical Field

[0001] The invention relates to the technical field of slitting machines, in particular to a raw material shearing device for producing metal decorative plates. Background Art

[0002] As a kind of metal decorative board, metal carved aluminum-zinc composite insulation board is made of alloy steel plate, which is laminated with special resin at high temperature, filled with hard polyurethane foam insulation, and pasted with aluminum foil. Metal carved aluminum-zinc composite insulation board is an energy-saving wall decoration building material developed in recent years. The surface is metal embossed with brick pattern, stone pattern, water ripple and other patterns. Metal coil is the main raw material for the production of metal carved aluminum-zinc composite insulation board.

[0003] For shorter metal decorative panels, shearing is generally completed by transverse shearing equipment, while for some metal decorative panels with narrow and long dimensions, longitudinal shearing machines are required to complete the shearing. The longitudinal shearing machine uses a rotating central shaft to drive multiple rotating disc knives on the outer wall to rotate to achieve shearing. The spacing between adjacent disc knives represents the width of the metal decorative panel after shearing, and the spacing between adjacent disc knives is generally fixed. When the spacing between adjacent disc knives needs to be changed, the disc knives and rotating shaft of the entire longitudinal shearing machine need to be disassembled and reinstalled with bolts.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] like Figures 1 to 11 As shown, the present invention includes the following embodiments:

[0034] Embodiment 1: A raw material shearing device for producing metal decorative plates, comprising a base 1; a shearing groove 11 is provided on the upper surface of the base 1 toward the front; the shearing groove 11 is rotatably connected to a rotating shaft 2 by the rear groove wall; the rear side of the base 1 is fixedly connected to a main motor 3 connected to the rear end of the rotating shaft 2; an adjusting groove 21 is provided along the axial direction at the front end of the rotating shaft 2; a clamping groove 22 is provided in communication with the outer wall of the rotating shaft 2; a first clamping block 4 is slidably connected in the clamping groove 22; an annular knife seat 5 is slidably sleeved on the outer wall of the rotating shaft 2 along the axial direction; the outer wall of the annular knife seat 5 is sleeved and connected An annular disc knife 51; the inner wall of the annular knife seat 5 is fixedly connected to the first clamping block 4; the adjusting groove 21 is rotatably connected to the adjusting rod 6 by the rear groove wall; the front end of the adjusting rod 6 extends to the outside of the adjusting groove 21; the first clamping block 4 is in contact with the outer wall of the adjusting rod 6; the outer wall of the adjusting rod 6 is fixedly connected to an arc-shaped clamping strip 61 with a notch; the notch is larger than the width of the clamping slot 22; a plurality of the clamping strips 61 are evenly distributed along the axial direction of the adjusting rod 6; the first clamping block 4 is provided with a first locking groove 41 circumferentially along the adjusting rod 6; the clamping strip 61 can be screwed into the first locking groove 41 as the adjusting rod 6 rotates.

[0035] In this embodiment, traction grooves 12 are provided on the upper surface of the base 1 on the left and right sides of the shear groove 11; a lower traction roller 13 is rotatably connected in the traction groove 12; an auxiliary motor 14 connected to one end of the lower traction roller 13 is fixedly connected to the front side of the base 1; the traction groove 12 protrudes from the outer wall of the lower traction roller 13; the upper surface of the base 1 is fixedly connected to the pressure seat 7; a pressure groove 71 is provided through the front and back of the pressure seat 7; a pressure block 72 is slidably connected to the pressure groove 71 up and down; the upper surface of the pressure block 72 is connected to the upper end of the pressure groove 71 by a compression spring 73; an upper traction roller 74 is rotatably connected between the two pressure blocks 72 in the front and rear directions; the upper traction roller 74 is located directly above the lower traction roller 13.

[0036] In this embodiment, the slot 22 passes through the rotating shaft 2 forward; the depth of the shear groove 11 increases as it moves away from the main motor 3; the end of the shear groove 11 away from the main motor 3 is fixedly connected to the transverse track 15; the transverse track 15 is connected to the support seat 8 for front and rear sliding; the support seat 8 is provided with a support hole 81 through the front and rear; the inner diameter of the support hole 81 is adapted to the outer diameter of the rotating shaft 2, and the support seat 8 can drive the support hole 81 along the transverse track 15 to be sleeved on the front end outer wall of the rotating shaft 2.

[0037] When working, before using the shearing equipment to shear the raw material for the production of metal decorative panels, namely the metal coil, the staff first installs and adjusts the position of the disc knife 51. Specifically, the staff first pushes the support seat 8 forward along the horizontal track 15, so that the support hole 81 on the support seat 8 is separated from the front end of the rotating shaft 2. One hand holds the outer wall of the front end of the rotating shaft 2, and the other hand rotates the front end of the adjusting rod 6. The front end of the adjusting rod 6 can be set to be flat, so that it is easy to twist. In the process of twisting the adjusting rod 6, the adjusting rod 6 will rotate in the adjusting groove 21, and the adjusting rod 6 will drive the clamping strip 61 on the outer wall to rotate. The clamping strip 61 is arc-shaped, and the notch position of the clamping strip 61 is As the adjusting rod 6 rotates and aligns with the slot 22, the annular knife seat 5 with the installed disc knife 51 is then moved to between the rear side of the support seat 8 and the front end of the rotating shaft 2. Then, the first clamping block 4 on the inner side of the annular knife seat 5 is aligned with the slot 22, and the annular knife seat 5 is sleeved on the outer wall of the rotating shaft 2. The annular knife seat 5 drives the first clamping block 4 to slide backward along the slot 22. In this way, the installation or replacement of the corresponding number of disc knives 51 is completed in sequence. Since the notch of the clamping strip 61 on the adjusting rod 6 is aligned with the slot 22, the clamping strip 61 will not hinder the movement of the first clamping block 4. Then, the support seat 8 is pushed to move backward along the horizontal track 15, so that the outer wall of the front end of the rotating shaft 2 is re-located in the support hole 81 Then start to adjust the position of the disc knife 51, push the disc knife 51 to drive the annular knife seat 5 to move axially along the rotating shaft 2, the distance between adjacent disc knives 51 affects the width of the raw material after shearing, and the position of the disc knife 51 directly affects the shearing position. After completing the movement and adjustment of the disc knife 51, use one hand to hold the outer wall of the rotating shaft 2, and use the other hand to rotate the adjusting rod 6 clockwise to start returning to its position. During the rotation of the adjusting rod 6, multiple clamping strips 61 on the outer wall will be driven to rotate synchronously and return to their positions. The end of the clamping strip 61 is tapered, so that the clamping strip 61 can be smoothly inserted into the first locking groove 41 on the first clamping block 4 after the adjusting rod 6 rotates, so that the first clamping block 4 is After the first clamping block 4 is locked, it cannot slide along the clamping groove 22, thereby locking the annular knife seat 5 and the disc knife 51, completing the process of adjusting the axial position of the disc knife 51 on the rotating shaft 2. When adjusting the disc knife 51 next time, the adjusting rod 6 is turned counterclockwise again, so that the adjusting rod 6 drives the clamping strip 61 to move out of the first locking groove 41 on the first clamping block 4, so that the notch on the clamping strip 61 is aligned with the clamping groove 22, so that the first clamping block 4 is unlocked, and after the first clamping block 4 moves along the clamping groove 22, the adjusting rod 6 is turned clockwise again, so that the clamping strip 61 is clamped into the first locking groove 41 on the first clamping block 4 again, so as to lock the first clamping block 4, and this process is repeated;

[0038] After the adjustment of the axial position of the disc knife 51 on the rotating shaft 2 is completed, the upper traction roller 74 is lifted. After the upper traction roller 74 is lifted, it will drive the pressure block 72 to overcome the compression spring 73 and move upward in the pressure groove 71. After the upper traction roller 74 moves up, a gap is formed between the corresponding lower traction roller 13. Then, the head end of the metal coil is moved through the gap between one of the upper traction rollers 74 and the lower traction roller 13 to the top of the shearing groove 11 to contact the disc knife 51. The rotating main motor 3 will drive the rotating shaft 2 to rotate. During the rotation of the rotating shaft 2, the first clamping block 4 and the annular knife seat 5 will be driven to rotate. During the rotation of the annular knife seat 5, the disc knife 51 will be driven to rotate. During the rotation of the disc knife 51, the metal coil will be sheared. After shearing The metal coil will be led out from the gap between the other upper traction roller 74 and the lower traction roller 13. The upper traction roller 74 presses the metal coil under the pressure of the compression spring 73. Under the rotation of the two auxiliary motors 14, the lower traction roller 13 will rotate to drive the metal coil to move. The metal coil is sheared by the disc knife 51 under tension, realizing the shearing process of raw materials for the production of metal decorative plates. During the shearing process of the metal coil, the debris cut from the top of the shearing groove 11 will fall into the bottom of the shearing groove 11 under the action of gravity, and the debris on the card slot 22 and the card strip 61 will be thrown into the shearing groove 11 under the centrifugal force generated by the rotation. The shearing groove 11 is inclined so that the debris can flow out along the bottom of the inclined shearing groove 11.

[0039] The present invention achieves rapid adjustment of the axial position of the disc cutter 51 on the rotating shaft 2 by sliding the first clamping block 4 on the inner side of the annular cutter seat 5 along the clamping groove 22 and then locking it. Compared with the existing adjustment method of the disc cutter 51, the present invention is faster, more convenient and more flexible.

[0040] Embodiment 2: The second clamping block 9 is slidably connected in the clamping groove 22; the outer wall of the rotating shaft 2 is axially slidably sleeved with an annular block seat 91; the annular block seat 91 is fixedly connected to the second clamping block 9; the outer wall of the annular block seat 91 is rotatably connected to an annular limiting plate 92; the outer diameter of the limiting plate 92 is larger than the outer diameter of the disc knife 51; the shape of the second clamping block 9 is consistent with that of the first clamping block 4; the second clamping block 9 is provided with a second locking groove 93 along the circumference of the adjusting rod 6; the clamping strip 61 can be screwed into the second locking groove 93 as the adjusting rod 6 rotates.

[0041] When the second clamping block 9 is in operation, when the notch on the clamping strip 61 is aligned with the clamping slot 22, the second clamping block 9 is in the unlocked state, and the second clamping block 9 can slide along the clamping slot 22, so that the annular stopper 91 can drive the limiting plate 92 to move along the axial direction of the rotating shaft 2, so as to change the axial position of the limiting plate 92 on the rotating shaft 2, so that the spacing between the two limiting plates 92 is changed, and the distance between the two limiting plates 92 is equal to the width of the metal coil to be sheared, and the limiting plate 92 is used to limit the edge of the metal coil to be sheared. After the limiting plates 92 complete the position adjustment, one hand holds the outer wall of the rotating shaft 2, and the other hand rotates the front end of the adjusting rod 6. During the rotation of the adjusting rod 6, the clamping strip 61 will be driven to rotate in the adjusting slot 21, and the clamping strip 61 will enter the second locking slot 93 during the rotation, thereby realizing the locking of the second clamping block 9. After the second clamping block 9 is locked, the axial positions of the two limiting plates 92 are locked by adjusting The axial position of the two limit plates 92 in the rotating shaft 2 makes the limit plates 92 after adjustment suitable for shearing metal coils of different widths, and plays a role in limiting the edges of metal coils of different specifications, so that the metal coils can be sheared more stably; in addition, the unlocking and locking methods of the limit plates 92 are also more flexible than the existing methods; during the shearing process of the disc cutter 51 driven by the rotating shaft 2, the rotating shaft 2 will drive the annular stopper 91 to rotate, but since the annular stopper 91 is rotatably connected to the limit plates 92, the limit plates 92 will not move with the rotation of the rotating shaft 2, thereby reducing the wear of the limit plates 92 during the process of limiting the edges of the metal coils; in addition, the outer diameter of the limit plates 92 is larger than the outer diameter of the disc cutter 51, so that the limit plates 92 can limit the edges of the metal coils before and after the disc cutter 51 shears, and the limiting effect is better; some parts such as balls and rollers can be set on the limit plates 92 to reduce the friction with the edges of the metal coils.

[0042] Embodiment 3: A square rod 23 is provided along the front-to-back direction directly above the rotating shaft 2; the square rod 23 is slidably connected to a limit seat 24 with a triangular cross-section in the front-to-back direction; the inner side of the limit seat 24 is connected to a metal conveyor belt 26 through a roller 25; the lower surface of the metal conveyor belt 26 is parallel to the upper surface of the base 1; a gap is left between the two metal conveyor belts 26 on the inner side of the limit seat 24; the upper position of the disc knife 51 is located between the corresponding two metal conveyor belts 26.

[0043] In this embodiment, the upper surface of the base 1 is fixedly connected to the vertical seat 16 at the rear position; the upper surface of the vertical seat 16 is provided with a vertical groove 17; the vertical groove 17 penetrates through the rear and is threadedly connected to a bolt 18; the vertical block 19 is connected to the vertical groove 17 so as to slide up and down; the upper end of the vertical block 19 is fixedly connected to the rear end of the square rod 23.

[0044] In this embodiment, the range of the lower surface of the metal conveyor belt 26 in the left-right direction is greater than the diameter of the disc knife 51 .

[0045] During operation, in the initial state, each disc knife 51 is located in the gap between the corresponding two metal conveyor belts 26. When the first clamping block 4 is unlocked, the first clamping block 4 and the annular knife seat 5 move axially along the rotating shaft 2, and the annular knife seat 5 will drive the disc knife 51 to move axially along the rotating shaft 2. During the movement of the disc knife 51 along the rotating shaft 2, the corresponding two metal conveyor belts 26 will be driven to move forward and backward, and the two metal conveyor belts 26 will drive the limiting seat 24 to move along the front and rear directions of the square rod 23. After the position adjustment of the disc knife 51 is completed, the first clamping block 4 is locked again, and then the bolt 18 is loosened, so that the vertical block 19 moves upward to drive the square rod 23 to move upward. The upward movement of the square rod 23 will drive the limiting seat 24 and the two metal conveyor belts 26 inside the limiting seat 24 to move upward. After the metal coil is pre-sheared from the upper position of the disc knife 51, the square rod 23 is put down. During the downward movement of the square rod 23, the limiting seat 24 and the two inner metal conveyor belts 26 will be driven The belt 26 moves downward until the two metal conveyor belts 26 flatten the metal coil bent upward, and the lower surface of the metal conveyor belt 26 is flush with the lower position of the outer wall of the upper traction roller 74, and the disc knife 51 is located in the gap between the two corresponding metal conveyor belts 26, and then the bolt 18 is tightened to lock the vertical block 19 in the vertical groove 17. During the rotation and shearing process of the disc knife 51, the shearing direction of the upper edge of the disc knife 51 is from left to right, and the cutting force of the disc knife 51 is from bottom to top. In addition, the stress of the metal coil itself is also bent upward. Therefore, through the shielding and limiting effect of the two metal conveyor belts 26 in the limiting seat 24, the metal coil is kept as flat as possible, so that the metal coil is sheared with higher quality and the shearing effect is improved; in addition, under the friction between the metal coil and the metal conveyor belt 26, the metal conveyor belt 26 will be driven along the roller 25 to reduce the friction between the metal conveyor belt 26 and the metal coil, and reduce the wear on the metal coil;

[0046] The contact range of the lower surface of the metal conveyor belt 26 in the left and right directions with the metal coil in this embodiment is much larger than the outer diameter of the disc knife 51, which can fully press and flatten the metal coil, so that the metal coil is not easy to bend under the shearing of the disc knife 51, and the incision is smoother. The metal conveyor belt 26 that provides support on both sides of the disc knife 51 can move back and forth with the movement of the disc knife 51, which is more convenient to adjust.

[0047] Embodiment 4: The outer wall at the front end of the adjusting rod 6 is symmetrically provided with centrifugal grooves 62; the bottoms of the two centrifugal grooves 62 are penetrated by a circular hole (not shown in the figure); the circular hole passes through an elastic rope (not shown in the figure); a centrifugal block 65 is slidably connected in the centrifugal groove 62; the two centrifugal blocks 65 are connected by an elastic rope on one side close to each other; the centrifugal blocks 65 have the same specifications as the centrifugal groove 62; the two centrifugal blocks 65 are adapted to the outer wall of the adjusting rod 6 on one side away from each other and are arc-shaped; the centrifugal block 65 extends out of the centrifugal groove 62 under the action of centrifugation and contacts the inner wall of the adjusting groove 21.

[0048] In this embodiment, the inner wall of the adjustment groove 21 is symmetrically provided with a first square groove 27 ; the cross section of the first square groove 27 is the same as the cross section of the centrifugal block 65 ; the adjustment rod 6 drives the centrifugal groove 62 to rotate so as to be aligned with the first square groove 27 .

[0049] In this embodiment, the upper surface and the side surface of the support seat 8 are connected to each other with an avoidance groove 82 ; the avoidance groove 82 passes through the support hole 81 ; the diameter of the support hole 81 is adapted to the outer diameter of the rotating shaft 2 .

[0050] During operation, after the first block 4 slides along the card slot 22, the adjusting rod 6 is rotated to rotate in the adjusting slot 21, and the adjusting rod 6 will drive the card strip 61 and the centrifugal slot 62 of the outer wall to rotate. The card strip 61 will be inserted into the first locking slot 41 after the adjusting rod 6 rotates, so as to lock the first block 4. The adjusting rod 6 stops rotating after driving the centrifugal slot 62 to align with the first square slot 27. It can be judged specifically by the correspondence between the flat direction of the front end of the adjusting rod 6 and the setting direction of the card slot 22. Then, the main motor 3 is started to drive the rotating shaft 2 to rotate. The rotation of the rotating shaft 2 will drive the adjusting rod 6 in the adjusting slot 21 to rotate, and the centrifugal slot 62 on the outer wall will be driven during the rotation of the adjusting rod 6. As well as the rotation of the centrifugal block 65, the centrifugal block 65 will generate centrifugal force during the rotation process around the center of the adjusting rod 6. The two centrifugal blocks 65 will move away from each other under the action of the centrifugal force and pull the elastic rope. The centrifugal block 65 will slide along the corresponding centrifugal groove 62. The centrifugal block 65 is slidably connected to the centrifugal groove 62. The sliding connection means that it can slide but cannot be separated. After the centrifugal block 65 extends out of the notch of the centrifugal groove 62, it will move close to the corresponding first square groove 27. Since the two centrifugal blocks 65 are in an arc shape at one end away from each other, the centrifugal block 65 can smoothly enter the first square groove 27 under the arc-shaped guidance of the end away from the elastic rope. Since one end of the centrifugal block 65 enters the first square groove 2 7, and the other end is located in the corresponding centrifugal groove 62, so the adjusting rod 6 is locked in the adjusting groove 21, so that the adjusting rod 6 will not produce relative rotation during the rotation of the rotating shaft 2, and the adjusting rod 6 will rotate synchronously with the rotation of the rotating shaft 2, so that the first clamping block 4 is further locked, thereby improving the stability of the disc knife 51; in addition, as the centrifugal force of the centrifugal block 65 increases, the end of the centrifugal block 65 away from the elastic rope will extend from the first square groove 27 into the avoidance groove 82, so that the support seat 8 is axially locked on the outer wall of the rotating shaft 2, so that the adjusting rod 6 and the support seat 8 are locked at the same time during the process of starting the disc knife 51 to rotate and shear; When the disc knife 51 and the rotating shaft 2 stop rotating, the centrifugal block 65 will be pulled close to the circular hole by the elastic rope, and the two centrifugal blocks 65 will move close to each other. The end of the centrifugal block 65 away from the elastic rope will move out of the avoidance groove 82 and the first square groove 27, and finally the centrifugal block 65 will return to the corresponding centrifugal groove 62, so that the adjusting rod 6 and the support seat 8 are unlocked. After the adjusting rod 6 is unlocked, it is convenient to rotate the adjusting rod 6, so as to realize the rapid adjustment of the first clamping block 4 after unlocking. After the support seat 8 is unlocked, the support seat 8 can move forward along the horizontal track 15, so that the support seat 8 is out of contact with the outer wall of the rotating shaft 2, and the disc knife 51 can be quickly removed and replaced.
