Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of tarpaulin processing, and relates to a cutting knife set and tarpaulin cutting knife set. BACKGROUND
[0002] Tarpaulin is one of the core components of a car cover, which is mainly covered on the top of the car cover framework to shield sunlight and rainwater. Since the shape of the car cover is not a standard shape, the required tarpaulin shape needs to be cut according to actual needs during actual production.
[0003] At present, when cutting tarpaulin, the tarpaulin on the tarpaulin roll is first pulled onto the multi-hole support table. After the tarpaulin is pulled to the designated position, the negative pressure cover under the support table is vacuumized, and the tarpaulin is stably laid on the top of the support table. Then the three-axis gantry is moved, and the cutting knife is driven to cut the tarpaulin, so as to obtain the required tarpaulin shape and size. The three-axis gantry is a conventional structure, which can drive the knife holder to move in X, Y and Z directions. The knife holder includes a fixed seat fixedly connected with the three-axis gantry and a motor (or a swing cylinder or other conventional structure capable of adjusting the angle) located on the fixed seat. The output shaft of the motor has a rotating seat, and the bottom of the rotating seat is rotatably connected with a rolling knife. When cutting the tarpaulin, the rolling knife rotates while cutting the tarpaulin. When cutting the tarpaulin at different positions, the motor drives the rotating seat to rotate, so that the rolling knife can smoothly cut the tarpaulin. Since the tarpaulin is hard and has high strength, the rolling knife needs to be replaced frequently during actual production. The common rolling knife is usually sleeved on a support column, and then a bolt is inserted into the free end of the support column. The rolling knife is limited by the bolt. Since the bolt needs to be unscrewed and installed every time, the operation efficiency is low. UTILITY MODEL CONTENTS

The same or similar reference numerals in the drawings represent the same or similar parts.
[0032] A cutting blade assembly, such as Figures 1 to 7 As shown, it includes:
[0033] The rotating seat 1 is vertically oriented (although it is named rotating seat 1, it may not rotate in actual use depending on the actual needs; for example, in the case of only straight cutting, the rotating seat 1 has a horizontal cylinder on its side, which drives the rotating seat 1 to move horizontally back and forth and to roll and cut the workpiece) and a support column 2 is horizontally set on the side of the rotating seat 1, with a limit hole 3 vertically penetrating the support column 2.
[0034] The rolling cutter 4 has a hole in its middle that mates with the support column 2, and the bottom of the rolling cutter 4 is lower than the rotating seat 1;

[0036] The elastic member 7 is continuously in a compressed state, and the bottom of the elastic member 7 continuously applies a downward force to the lifting column 5.

[0038] The top of the lifting groove is lower than the top of the lifting seat 8, the elastic member 7 is located in the lifting groove, and the top of the elastic member 7 is connected with the inner wall of the top of the lifting groove, and the bottom is connected with the top of the lifting platform 9.
[0039] The outer side of the lifting platform 9 is provided with a cover plate 10, the width of the cover plate 10 is greater than the width of the opening side of the lifting groove, the opening side of the lifting groove is opposite to the inner side of the cover plate 10, and the cover plate 10 is movably attached to the outer side of the lifting seat 8.
[0040] The outer side of the cover plate 10 is horizontally provided with a rotating column 11, the outer wall of the rotating column 11 is rotatably sleeved with a rotating member 12, the side of the rotating member 12 is movably attached to the cover plate 10, the bottom is fixedly connected with the top of the lifting column 5, and the outer side of the lifting seat 8 is provided with a fixing mechanism for fixing the position of the rotating member 12; wherein the cover plate 10 covers the opening side of the lifting groove, so that when the rotating member 12 rotates, the inner side of the rotating member 12 is attached to the cover plate 10, and wear between the inner side of the rotating member 12 and the opening side of the lifting groove is avoided, the situation of "stuck" is prevented, and the operation stability is ensured; meanwhile, the cover plate 10 can pass through the accommodation groove 14, that is, the fixing body 13 does not affect the lifting of the cover plate 10.
[0041] The fixing mechanism comprises two fixing bodies 13 vertically arranged outside the lifting seat 8, the two fixing bodies 13 are located on the two sides of the opening side of the lifting groove, the inner side of the fixing body 13 is provided with a gap slot 14 for the movable passing of the cover plate 10, the side of the lifting column 5 close to the cover plate 10 is provided with a passing groove 15, the plane where the outer side of the fixing body 13 is located is between the vertical inner wall of the passing groove 15 and the lifting seat 8, so that when the rotating part 12 rotates relative to the rotating column 11, the existence of the passing groove 15 enables the lifting column 5 to normally pass through the fixing body 13; meanwhile, the existence of the passing groove 15 reduces the friction area between the side of the rolling cutter 4 and the lifting column 5, reduces the wear of the rolling cutter 4 and the lifting column 5, and reduces the noise generated by the two;
[0042] The rotating part 12 is elliptical, and the center of the rotating part 12 is located on the axis of the rotating column 11; the rotating part 12 comprises a first state and a second state.
[0043] When the rotating part 12 is in the first state, the cross rod body 6 abuts against the top of the supporting column 2, the passing groove 15 is higher than the supporting column 2, and the two ends of the minor axis of the rotating part 12 abut against the two fixing bodies 13 respectively.
[0044] When the rotating part 12 is in the second state, the lifting column 5 is horizontal, and the top of the two fixing bodies 13 abuts against the lower side of the rotating part 12.
[0045] The utility model also provides a kind of tarpaulin cutting knife group, including the cutting knife group of any one described above, i.e. the structure of the application can be used to tarpaulin in production process is cut.
[0046] The cutting knife group provided by the utility model can be lifted and rotated when cutting operation is carried out. The mechanism for lifting and rotating the rotating seat 1 is not within the scope of the application, but preferably a (xyz) three-axis gantry, and the three-axis gantry has a fixed seat, a (servo) motor on the fixed seat, and the output shaft of the motor is connected to the rotating seat 1. This way, the rotating seat 1 can be controlled to lift and rotate, and the corresponding cutting object can be cut. It should also be understood that controlling the rotating seat 1 is not within the scope of the application, and will not be described in detail here.
[0047] In the process of cutting, the bottom of the rolling cutter 4 is lower than the rotating seat 1, and one side of the rolling cutter 4 is movably attached to the rotating seat 1, and the other side is movably attached to the lifting column 5, so that the relative position between the rolling cutter 4 and the rotating seat 1 can be stable; at the same time, the rolling cutter 4 is movably sleeved on the supporting column 2, so that the rolling cutter 4 can be cut in a rotating manner, so that the cutting process can be carried out normally. At the same time, since the lifting column 5 is continuously subjected to the downward elastic force of the elastic member 7, and the cross rod body 6 abuts against the top of the supporting column 2, the position stability of the rolling cutter 4 is ensured.
[0048] Then when replacing the rolling cutter 4 or taking off the rolling cutter 4 for grinding, only need to raise the lifting column 5 upward through the cross rod body 6, and make the lifting column 5 separate from the supporting column 2, after the lifting column 5 is moved to a position that does not affect the movement of the rolling cutter 4, the rolling cutter 4 can be directly taken off from the supporting column 2. After replacing or grinding the rolling cutter 4 is completed, the rolling cutter 4 is directly sleeved on the supporting column 2, and then the lifting column 5 passes through the limiting hole 3 from top to bottom, and the cross rod body 6 abuts against the top of the supporting column 2, so that the limiting of the rolling cutter 4 is completed, which is simple and convenient, and improves the efficiency.
[0049] In addition, when the conventional rolling cutter 4 is positioned by bolts, the bolts may be loose or even fall off with the increase of use time. However, in the present application, the lifting column 5 is continuously subjected to the downward elastic force, so that the position of the lifting column 5 can be maintained regardless of use, and the rolling cutter 4 is prevented from loosening or falling off.
[0050] In actual use, the top of the elastic member 7 abuts against the inner wall of the lifting groove top, and the bottom abuts against the top of the lifting platform 9; at the same time, since the cross rod body 6 abuts against the supporting column 2 in the vertical direction, the lifting platform 9 cannot continue to move downward, so that the lifting column 5 can stably limit the outer side of the rolling cutter 4.
[0051] When the rolling cutter 4 needs to be replaced or ground, the worker only needs to manually move the cross rod body 6 upward, and the lifting column 5, the rotating member 12, the rotating column 11, the covering plate 10 and the lifting platform 9 are all raised, and the elastic member 7 is further compressed (which can be a spring, but is preferably a wave-shaped elastic structure, which can be better accommodated in the lifting groove); at this time, during the lifting process, the two sides of the rotating member 12 are limited by the fixing body 13, so that the rotating member 12 and the lifting column 5 can stably maintain the angle of elevation.
[0052] After the rotating member 12 is raised slightly higher than the fixed body 13, the horizontal swing crossbar body 6 is swung 90 degrees, and then the height of the rotating member 12 is lowered, so that both fixed bodies 13 finally abut against the lower side of the rotating member 12, thereby temporarily supporting the rotating member 12; since the elastic member 7 exerts greater elastic force downward at this time, and the bottom end of the rotating member 12 is located between the two fixed bodies 13, the position and angle of the rotating member 12 can be stably maintained, which facilitates workers to remove and install new rolling knives 4.
[0053] After the new rolling knife 4 is installed, the rotating member 12 is slightly raised (manually), the lifting column 5 is kept vertical by rotating the crossbar body 6, then the crossbar body 6 is lowered and the lifting column 5 passes through the limiting hole 3, until the crossbar body 6 abuts against the top of the supporting column 2, thereby limiting the rolling knife 4, which is simple and convenient. Since the rotating member 12 is elliptical, the lifting column 5 does not need to be completely rotated to the vertical state when it is lowered, but only needs to be close to the vertical state; during the lowering process of the rotating member 12, the fixed body 13 guides and turns the rotating member 12 to the vertical state, which is more convenient to operate.
[0054] It should be further pointed out that all the "provision" and similar descriptions in the present application (especially the specification) express that there is a connection relationship between two structures, but the specific connection means is not limited, and is usually a conventional connection means, that is, it should be understood that the means is prior art, and does not need to be described in detail. For example, "a is provided with b", only expresses that a structure is provided with b structure, and the specific connection between the two is through welding, riveting, adhesive connection or integral molding, which is within the protection scope of the present application; for example, "c is provided with d", only expresses that d is rotatably connected with c, and whether the two are rotatably connected through a bearing or d directly penetrates c to be rotatably connected with c, which is within the protection scope of the present application.
[0055] The above description is only a description of the preferred embodiment of the present application, and is not any limitation on the scope of the present application. Any modification and modification of the above disclosure by a person skilled in the art is within the protection scope of the claims.
