Description
Technical Field
[0001] The utility model relates to the technical field of material cutting equipment, in particular to a cutting mechanism and a cutting equipment. Background Art
[0002] When the existing material cutting equipment cuts workpieces to be cut such as insulation boards, the insulation boards need to be cut into multiple segments. Since the cutting direction of the saw teeth of the saw blade of the cutting machine generally can only be unidirectional cutting, that is, the saw blade rotates in one direction and cuts when moving, and cannot cut when rotating and moving in the other opposite direction. Therefore, there are mainly two cutting methods when the existing material cutting equipment cuts the insulation board into multiple segments. The first cutting method is that after the saw blade completes one cutting, the cutting direction of the saw teeth of the saw blade is turned 180° and then the next segment is cut. The second cutting method is that after the saw blade cuts from one end of the insulation board to the other end to complete one segment of cutting, the saw blade switches to the no-load state of non-cutting, and then the saw blade or the insulation board is moved so that the saw blade returns to one end of the insulation board, and then the saw blade is started to cut from one end of the insulation board to the other end to complete the next segment of cutting. The cutting processes of the above two cutting methods are relatively cumbersome and have low efficiency. Summary of the Utility Model

In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example.
[0047] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
[0048] Unless otherwise specified or defined, the term "and / or" used in the present utility model includes any and all combinations of one or more of the related listed items.
[0049] For the convenience of description, unless otherwise specified, the up-down direction mentioned below is consistent with the up-down direction of Figure 1 itself, the left-right direction mentioned below is consistent with the left-right direction of Figure 1 itself, and the front-back direction mentioned below is consistent with the up-down direction of Figure 5 itself.
[0050] As Figures 1 to 5 shown, this embodiment provides a cutting mechanism 1, including a base 11, a first saw blade 12, a second saw blade 13, a first rotation driver 14, a second rotation driver 15, a first linear driver 16, and a second linear driver 17. Both the first saw blade 12 and the second saw blade 13 are thin circular cutting tools for cutting solid materials. A number of saw teeth are circumferentially distributed on the outer circumferential side surfaces of the first saw blade 12 and the second saw blade 13. When the first saw blade 12 and the second saw blade 13 rotate in one direction, the saw teeth can cut the workpiece to be cut. When the first saw blade 12 and the second saw blade 13 rotate in another opposite direction, the saw teeth cannot cut the workpiece to be cut.
[0051] The rotation axis of the first saw blade 12 is parallel to the rotation axis of the first saw blade 12, and the cutting direction of the saw teeth of the first saw blade 12 is opposite to the cutting direction of the saw teeth of the second saw blade 13. For example, in Figure 1 , when the first saw blade 12 rotates clockwise and the first saw blade 12 moves linearly from left to right relative to the workpiece to be cut, the saw teeth of the first saw blade 12 can cut the workpiece to be cut. When the first saw blade 12 moves linearly from right to left relative to the workpiece to be cut, the saw teeth of the first saw blade 12 cannot cut the workpiece to be cut. When the first saw blade 12 rotates counterclockwise, the first saw blade 12 cannot cut the workpiece to be cut whether it moves linearly from left to right or from right to left relative to the workpiece to be cut. When the second saw blade 13 rotates counterclockwise and the second saw blade 13 moves linearly from right to left relative to the workpiece to be cut, the saw teeth of the second saw blade 13 can cut the workpiece to be cut. When the second saw blade 13 moves linearly from left to right relative to the workpiece to be cut, the saw teeth of the second saw blade 13 cannot cut the workpiece to be cut. When the second saw blade 13 rotates clockwise, the second saw blade 13 cannot cut the workpiece to be cut whether it moves linearly from left to right or from right to left relative to the workpiece to be cut. When the first saw blade 12 moves linearly relative to the workpiece to be cut, it can be by moving the base 11 to drive the first saw blade 12 to move, or by driving the workpiece to be cut to move linearly. Similarly, when the second saw blade 13 moves linearly relative to the workpiece to be cut, it can be by moving the base 11 to drive the second saw blade 13 to move, or by driving the workpiece to be cut to move linearly, so as to enable the first saw blade 12 and the second saw blade 13 to cut the workpiece to be cut.
[0052] The first saw blade 12 is rotatably mounted on the base 11 and can slide along the radial direction of the first saw blade 12 itself. The first saw blade 12 can be slidably mounted by means of a slide base or the like, or can be mounted on a wheel axle, and the wheel axle is slidably mounted on the base 11. The second saw blade 13 is rotatably mounted on the base 11 and can slide along the radial direction of the second saw blade 13 itself. The second saw blade 13 can be slidably mounted by means of a slide base or the like, or can be mounted on a wheel axle, and the wheel axle is slidably mounted on the base 11.
[0053] The first rotation driver 14 is in transmission connection with the first saw blade 12 to drive the first saw blade 12 to rotate. The first rotation driver 14 includes devices such as a motor, and directly or indirectly drives the first saw blade 12 to rotate in one direction through the motor, so as to cut the workpiece to be cut along the first straight line direction. The second rotation driver 15 is in transmission connection with the second saw blade 13 to drive the second saw blade 13 to rotate. The second rotation driver 15 includes devices such as a motor, and directly or indirectly drives the second saw blade 13 to rotate in a direction opposite to the rotation direction of the first saw blade 12 through the motor, so as to cut the workpiece to be cut along the direction opposite to the first straight line direction. Through the first saw blade 12 and the second saw blade 13, reciprocating cutting of the workpiece to be cut is realized.
[0054] The first linear driver 16 is in transmission connection with the first saw blade 12 to drive the first saw blade 12 to approach or move away from the workpiece to be cut. The second linear driver 17 is in transmission connection with the second saw blade 13 to drive the second saw blade 13 to approach or move away from the workpiece to be cut. The first linear driver 16 and the second linear driver 17 can work alternately, so that the first saw blade 12 and the second saw blade 13 can be alternately used to cut the workpiece to be cut. Exemplarily, the workpiece to be cut is located on the right side of the cutting mechanism 1. When the cutting mechanism 1 works, it drives the base 11 and / or the workpiece to be cut to perform horizontal linear movement in the left-right direction, so as to realize the relative movement between the base 11 and the workpiece to be cut. When the base 11 moves from left to right relative to the workpiece to be cut, the first rotation driver 14 drives the first saw blade 12 to rotate, so that the first saw blade 12 cuts the workpiece to be cut. After the workpiece to be cut moves to the left side of the first saw blade 12, the first section of the workpiece to be cut is completed. When the next section needs to be cut, it is not necessary to first drive the first saw blade 12 to stop and move the workpiece to be cut back to the right side of the cutting mechanism 1. At this time, the first saw blade 12 can be first stopped from rotating and moved downward, and the second saw blade 13 is driven to move upward. The base 11 moves back and forth relative to the workpiece to be cut to adjust the cutting position. Then the second rotation driver 15 drives the second saw blade 13 to rotate and moves the workpiece to be cut from the left side of the second saw blade 13 to the right side of the second saw blade 13, so as to complete the cutting of the second section of the workpiece to be cut. Then, the cutting processes of the first section and the second section are repeated to cut the workpiece to be cut into multiple sections.
[0055] In this way, the present application switches the first saw blade 12 and the second saw blade 13 with opposite cutting directions through the first linear drive 16 and the second linear drive 17. The cutting mechanism 1 does not need to move unloaded to the same side of the workpiece to be cut for the next cutting, thereby realizing rapid and continuous cutting of the workpiece to be cut and improving the cutting efficiency of the workpiece to be cut.
[0056] In one embodiment, the base 11 includes a first base body 111 and a first slide 112 slidably provided on the first base body 111 along the radial direction of the first saw blade 12 and a second slide 113 slidably provided on the first base body 111 along the radial direction of the second saw blade 13. The first slide 112 and the second slide 113 slide along the vertical direction, the first linear drive 16 is transmission-connected with the first slide 112, and the second linear drive 17 is transmission-connected with the second slide 113. The first linear drive 16 can drive the first slide 112 to slide up and down, and the second linear drive 17 can drive the second slide 113 to slide up and down, so that the first saw blade 12 and the second saw blade 13 can slide close to the workpiece to be cut when they slide upward, and can slide away from the workpiece to be cut when they slide downward.
[0057] The first rotary driver 14 includes a first motor 141 mounted on the first seat 111, a first driving pulley 142 rotatably mounted on the first seat 111 and transmission-connected to the first motor 141, a first driven pulley 143 rotatably mounted on the first slide 112, and a first transmission belt 144 sleeved on the first driving pulley 142 and the first driven pulley 143. The second rotary driver 15 includes a second motor 151 mounted on the first seat 111, a second driving pulley 152 rotatably mounted on the first seat 111 and transmission-connected to the second motor 151, a second driven pulley 153 rotatably mounted on the second slide 113, and a second transmission belt 154 sleeved on the second driving pulley 152 and the second driven pulley 153. The first saw blade 12 is transmission-connected to the first driven pulley 143, and the second saw blade 13 is transmission-connected to the second driven pulley 153.
[0058] The first linear driver 16 and the second linear driver 17 can be components such as cylinders, hydraulic cylinders, pneumatic telescopic rods, lead screw modules, etc. When the first linear driver 16 drives the first sliding seat 112 to move upward, the first driven pulley 143 and the first saw blade 12 move upward, making the first transmission belt 144 in a pre-tensioned state. The first driving pulley 142 can drive the first driven pulley 143 to rotate through the first transmission belt 144, so that the first saw blade 12 can rotate to cut the workpiece to be cut. Similarly, when the second linear driver 17 drives the second sliding seat 113 to move upward, the second driven pulley 153 and the second saw blade 13 move upward, making the second transmission belt 154 in a pre-tensioned state. The second driving pulley 152 can drive the second driven pulley 153 to rotate through the second transmission belt 154, so that the second saw blade 13 can rotate to cut the workpiece to be cut. When the first linear driver 16 drives the first sliding seat 112 to move downward, the first saw blade 12 moves away from the workpiece to be cut, and the first transmission belt 144 becomes slack. At this time, the first driving pulley 142 cannot drive the first driven pulley 143 to rotate through the first transmission belt 144, thereby preventing the first saw blade 12 from idling. When the second linear driver 17 drives the second sliding seat 113 to move downward, the second saw blade 13 moves away from the workpiece to be cut, and the second transmission belt 154 becomes slack. At this time, the second driving pulley 152 cannot drive the second driven pulley 153 to rotate through the second transmission belt 154, thereby preventing the second saw blade 13 from idling.
[0059] In other embodiments, the base 11 includes a second seat body, a third sliding seat slidably disposed along the radial direction of the first saw blade 12 on the second seat body, and a fourth sliding seat slidably disposed along the radial direction of the second saw blade 13 on the second seat body. The first rotation driver 14 includes a third motor mounted on the third sliding seat. The second rotation driver 15 includes a fourth motor mounted on the fourth sliding seat. The first saw blade 12 is rotatably mounted on the third sliding seat and is in transmission connection with the third motor. The second saw blade 13 is rotatably mounted on the fourth sliding seat and is in transmission connection with the fourth motor. The first rotation driver 14 and the first saw blade 12 are both mounted on the third sliding seat, and the second rotation driver 15 and the second saw blade 13 are both mounted on the fourth sliding seat, reducing the installation difficulty of the first rotation driver 14 and the first saw blade 12, the second rotation driver 15 and the second saw blade 13, and improving the transmission reliability of the first rotation driver 14 and the second rotation driver 15.
[0060] Further, a first guide rod 114 and a second guide rod 115 are installed on the first body 111 or the second body. In order to improve the sliding stability of the first sliding seat 112, the second sliding seat 113, the third sliding seat, and the fourth sliding seat, there are two first guide rods 114 and two second guide rods 115. The two first guide rods 114 are arranged at intervals and are both vertically arranged. The two second guide rods 115 are arranged at intervals and are both vertically arranged. The two ends of the first sliding seat 112 are respectively slidably arranged on the two first guide rods 114, or the two ends of the third sliding seat are respectively slidably arranged on the two first guide rods 114. The two ends of the second sliding seat 113 are respectively slidably arranged on the two second guide rods 115, or the two ends of the fourth sliding seat are respectively slidably arranged on the two fourth guide rods. Through the guiding of the first guide rod 114 and the second guide rod 115, the stability of the first saw blade 12 and the second saw blade 13 moving along the direction of approaching or departing from the workpiece to be cut is improved.
[0061] Optionally, the first saw blade 12 and the second saw blade 13 are arranged at intervals along the rotation axis of the first saw blade 12 or the rotation axis of the second saw blade 13. That is, the plane where the first saw blade 12 is located and the plane where the second saw blade 13 is located are arranged at intervals and are parallel to each other. In this way, the cutting positions when the first saw blade 12 rises for cutting are different from those when the second saw blade 13 rises for cutting. After the first saw blade 12 finishes cutting, when the second saw blade 13 cuts the next section of the workpiece to be cut, it may not be necessary to adjust the cutting position or reduce the moving distance of adjusting the cutting position.
[0062] Optionally, one radial direction of the first saw blade 12 and one radial direction of the second saw blade 13 are collinear, that is, the plane where the first saw blade 12 is located and the plane where the second saw blade 13 is located are coplanar, which is convenient for the first saw blade 12 and the second saw blade 13 to perform cutting positioning. After the first saw blade 12 finishes cutting, based on the first saw blade 12, the driving base 11 and the workpiece to be cut are moved along the rotation axis direction of the first saw blade 12 or the rotation axis direction of the first saw blade 12, so that the second saw blade 13 can be moved more precisely to the next cutting position of the workpiece to be cut.
[0063] In one embodiment, the cutting mechanism 1 further includes a measuring instrument 18 for measuring the sliding positions of the first saw blade 12 and the second saw blade 13. The measuring instrument 18 is installed on the base 11. Specifically, the first saw blade 12 and the second saw blade 13 can move up and down to approach or depart from the workpiece to be cut. The measuring instrument 18 is a height measuring instrument, abbreviated as a height gauge or altimeter, which is mainly used to measure the height of an object. Through the measuring instrument 18, the positions of the first saw blade 12 and the second saw blade 13 can be detected, and the positions of the first saw blade 12 and the second saw blade 13 can be monitored, so as to avoid incorrect use of the first saw blade 12 and the second saw blade 13 for cutting during cutting.
[0064] Furthermore, the sliding direction of the first saw blade 12 is parallel to that of the second saw blade 13. The sliding direction of the first saw blade 12 and that of the second saw blade 13 may form an angle. For example, the first saw blade 12 may be inclined upward to approach or move away from the workpiece to be cut, and the second saw blade 13 may be vertically upward to approach or move away from the workpiece to be cut. In order to reduce the moving stroke of the first saw blade 12 and the second saw blade 13 and improve the switching efficiency of the first saw blade 12 and the second saw blade 13, both the first saw blade 12 and the second saw blade 13 slide along the vertical direction to approach or move away from the workpiece to be cut.
[0065] This embodiment also provides a cutting device, which includes a material rack 2 and the cutting mechanism 1 of any one of the above embodiments. The material rack 2 has a processing part for placing the workpiece to be cut, and the processing part is used to support the workpiece to be cut. The base 11 is slidably arranged on the material rack 2 along the radial direction of the first saw blade 12 or the second saw blade 13. The base 11 can be manually pushed to slide, or the base 11 can be equipped with a power system 19, and the base 11 slides left and right on the material rack 2 through the power system 19. The processing part is located on the sliding path of the base 11, and the processing part is located on the sliding paths of the first saw blade 12 and the second saw blade 13. When the base 11 passes through the processing part, the first saw blade 12 or the second saw blade 13 can cut the workpiece to be cut. During cutting, the first saw blade 12 or the second saw blade 13 can be switched to cut the workpiece to be cut according to the moving direction of the base 11.
[0066] Optionally, the power system 19 can be realized by means of a cylinder, a lead screw module, a gear-rack combination, etc. to move the base 11 along the left and right directions of the material rack 2.
[0067] It can be understood that in other embodiments, the base 11 can also be fixedly installed, and the workpiece to be cut is transported close to the first saw blade 12 and the second saw blade 13 on the base 11 by manual or feeding equipment.
[0068] Furthermore, a conveying mechanism 3 is provided at the processing part of the material rack 2, and the conveying mechanism 3 has a conveying channel extending along the axial direction of the first saw blade 12 or the second saw blade 13. Specifically, the conveying mechanism 3 includes a conveyor belt or a conveying chain. The conveying channel is located on the conveyor belt or the conveying chain. There are multiple conveyor belts or conveying chains arranged at intervals. By using the conveying mechanism 3, the workpiece to be cut can be driven to move along the axial direction of the first saw blade 12 or the second saw blade 13, so that the cutting position of the first saw blade 12 or the second saw blade 13 on the workpiece to be cut can be adjusted.
