Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plate cutting machines, in particular to a cutting equipment for composite plate processing. BACKGROUND

[0002] Composite plate refers to a plate composed of two or more materials. In fact, the concept and manufacturing method of composite plate are different for different materials. In daily life, the commonly used composite plates are mainly metal composite plates, wood-plastic composite plates and glass steel composite plates.

[0003] Composite plates need to be cut to different lengths according to actual needs in production and processing, so as to improve the range of use. During the cutting process of the composite plate, a large amount of dust will be generated, so a dust removal device needs to be installed to remove dust from the cutting equipment.

[0004] The existing dust removal device is usually installed at a fixed position of the equipment, so the range of dust adsorption is limited, which will affect the dust removal effect during cutting. Therefore, a cutting equipment for composite plate processing is needed to solve the above problems. SUMMARY

[0005] In view of the problems in the prior art, the purpose of the embodiment of the present application is to provide a cutting equipment for composite plate processing to solve the problems in the background art.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical scheme:

[0007] A cutting equipment for composite plate processing, comprising:

[0008] A support seat, wherein a cutting machine is installed in the support seat;

[0009] A reciprocating unit rotatably connected in the support seat and connected with the cutting machine, used to drive the cutting machine to reciprocate up and down;

[0010] A guide unit fixed on the support seat and connected with the reciprocating unit, used to guide and limit the reciprocating unit;

[0011] A feeding unit rotatably connected on the support seat and connected with the reciprocating unit, used to rotate under the action of the reciprocating unit, thereby driving the composite plate to transmit power;

[0012] A dust removal unit rotatably connected on the support seat, used to remove dust from the cutting machine;

[0013] A rotating unit rotatably connected on the support seat and connected with the dust removal unit, used to drive the dust removal unit to reciprocate and rotate alternately;

[0014] The self-rotation unit is fixed on the support base and connected with the dust removal unit, and is used to drive the dust removal unit to rotate.

[0015] Compared with the prior art, the embodiment of the present application has the following beneficial effects: the reciprocating unit is rotatably connected in the support base and connected with the cutting machine, and is used to drive the cutting machine to reciprocate up and down; the guide unit is fixed on the support base and connected with the reciprocating unit, and is used to guide and limit the reciprocating unit; the feeding unit is rotatably connected in the support base and connected with the reciprocating unit, and is used to rotate under the action of the reciprocating unit, thereby driving the composite board to transmit power; the dust removal unit is rotatably connected in the support base, and is used to remove dust from the cutting machine; the rotating unit is rotatably connected in the support base and connected with the dust removal unit, and is used to drive the dust removal unit to reciprocate alternately; and the self-rotation unit is fixed on the support base and connected with the dust removal unit, and is used to drive the dust removal unit to rotate.

[0016] When the composite board is processed and cut, the cutting machine and the reciprocating unit are turned on, the reciprocating unit can drive the cutting machine to slide up and down under the action of the guide unit, so that the cutting machine can cut the composite board periodically. The reciprocating unit can drive the feeding unit to feed the composite board when it rotates, thereby facilitating the cutting machine to cut the composite board periodically.

[0033] In the embodiment of the present application, when the composite board is processed and cut, the cutting machine 11 and the reciprocating unit 2 are turned on, the reciprocating unit 2 can drive the cutting machine 11 to slide up and down under the action of the guide unit 3, so that the cutting machine 11 can cut the composite board periodically. The reciprocating unit 2 can drive the feeding unit 4 to feed the composite board when rotating, thereby facilitating the cutting machine 11 to cut the composite board periodically. The dust removal unit 5 is turned on, which can adsorb the dust generated during the cutting process of the composite board into the dust bag. The rotating unit 6 is turned on, which can drive the dust removal unit 5 to reciprocate and alternately rotate by a certain angle; and the dust removal unit 5 can rotate under the action of the rotation unit 7 when rotating, so that the dust removal unit 5 can alternately rotate in the direction of the two shafts, increasing the adsorption range of the dust removal unit 5 to the dust generated during the cutting process of the composite board, effectively improving the adsorption effect of the dust.

[0034] In one embodiment of the present application, as shown in Figure 1 and Figure 2 The reciprocating unit 2 comprises:

[0035] The driving member 21 is installed on the support base 1.

[0036] The rotating shaft 22 is rotatably connected to the support base 1, and the end is connected to the output end of the driving member 21.

[0037] The eccentric wheel 23 is installed on the surface of the rotating shaft 22, and the surface is rotatably connected with the inner ring 24.

[0038] The outer ring 26 is connected to the outer surface of the inner ring 24 through the rubber ring 25.

[0039] In this embodiment, the driving member 21 is installed on the support base 1; the rotating shaft 22 is rotatably connected to the support base 1, and the end is connected to the output end of the driving member 21; the eccentric wheel 23 is installed on the surface of the rotating shaft 22, and the surface is rotatably connected with the inner ring 24; the outer ring 26 is connected to the outer surface of the inner ring 24 through the rubber ring 25.

[0040] When the composite board is processed and cut, the cutting machine 11 and the driving member 21 are started, and the output end of the driving member 21 can drive the eccentric wheel 23 on the surface thereof to rotate through the rotating shaft 22. When the eccentric wheel 23 rotates, the inner ring 24 on the surface thereof can be driven to reciprocatingly slide up and down, so that the inner ring 24 can drive the outer ring 26 to synchronously reciprocatingly slide up and down through the rubber ring 25, the guide unit 3 can guide and limit the outer ring 26, so that the outer ring 26 can guide and limit the inner ring 24 through the rubber ring 25, and then the inner ring 24, the rubber ring 25 and the outer ring 26 as a whole reciprocatingly slide up and down, and the eccentric wheel 23 can rotate in the inner ring 24.

[0041] When the inner ring 24, the rubber ring 25 and the outer ring 26 as a whole reciprocatingly slide up and down, the cutting machine 11 can be synchronously driven to slide, so that the cutting machine 11 can cut the composite board. When the rotating shaft 22 rotates, the feeding unit 4 can feed the composite board, and the stability of feeding the composite board is improved.

[0042] When the outer ring 26 slides, the rubber ring 25 can buffer the outer ring 26, so that the cutting machine 11 and the composite board are prevented from being hard mechanically collided. The driving member 21 can be a servo motor or a pneumatic motor, and the rotating shaft 22 can be conveniently and stably driven to rotate.

[0043] In an embodiment of the present application, as shown in the figure, Figure 1 The guide unit 3 comprises:

[0044] The connecting frame 31 is connected to the outer ring 26, and the surface thereof is provided with the sliding groove 32;

[0045] The fixed frame 33 is fixed to the support base 1, and the sliding rod 34 is slidably connected in the fixed frame 33, and the sliding rod 34 is slidably connected with the sliding groove 32;

[0046] The elastic member 35 is connected between the fixed frame 33 and the connecting frame 31;

[0047] The bolt 36 is mounted on the surface of the sliding rod 34, and two groups of the bolt 36 are mounted and slidably connected with the side surface of the connecting frame 31.

[0048] In the embodiment, the connecting frame 31 is connected to the outer ring 26, and the surface thereof is provided with the sliding groove 32; the fixed frame 33 is fixed to the support base 1, and the sliding rod 34 is slidably connected in the fixed frame 33, and the sliding rod 34 is slidably connected with the sliding groove 32; the elastic member 35 is connected between the fixed frame 33 and the connecting frame 31; the bolt 36 is mounted on the surface of the sliding rod 34, and two groups of the bolt 36 are mounted and slidably connected with the side surface of the connecting frame 31.

[0049] The outer ring 26 can drive the connecting frame 31 to move up and down synchronously when moving up and down reciprocally, so that the connecting frame 31 can drive the sliding rod 34 to move up and down reciprocally in the fixed frame 33 through the sliding connection of the sliding groove 32 and the bolt 36, and the bolt 36 can limit the sliding rod 34, facilitating the sliding of the connecting frame 31 and the sliding rod 34.

[0050] When the connecting frame 31 drives the sliding rod 34 to slide, the elastic member 35 can be compressed, so that the elastic member 35 can buffer the connecting frame 31, improving the protection performance of the connecting frame 31. Since the eccentric wheel 23 rotates circumferentially, the connecting frame 31 can also drive the sliding groove 32 to slide on the surface of the sliding rod 34. The connecting frame 31 can periodically drive the cutting machine 11 to slide downward, so that the cutting machine 11 can cut and process the composite board when the cutting machine 11 slides downward to contact the composite board.

[0051] The bolt 36 in the guide unit 3 can also be replaced by a sliding member, which is fixed on the surface of the sliding rod 34 and is in sliding connection with the sliding groove 32. The connecting frame 31 can drive the sliding groove 32 to slide on the surface of the sliding member, and the connecting frame 31 can drive the sliding rod 34 to slide in the fixed frame 33 through the connection of the sliding groove 32 and the sliding member.

[0052] The elastic member 35 can be a spring or elastic rubber, which can buffer the connecting frame 31.

[0053] In an embodiment of the present application, as shown in Figure 1 The feeding unit 4 comprises:

[0054] The transmission rod 41 is rotationally connected in the support base 1 and is provided with the transmission roller 42 on the surface.

[0055] The belt 43 is connected between the transmission rod 41 and the rotating shaft 22.

[0056] The limiting frame 44 is fixed on the support base 1 and is in sliding connection with the composite board, and is used for guiding and limiting the composite board.

[0057] In the embodiment, the transmission rod 41 is rotationally connected in the support base 1 and is provided with the transmission roller 42 on the surface; the belt 43 is connected between the transmission rod 41 and the rotating shaft 22; and the limiting frame 44 is fixed on the support base 1 and is in sliding connection with the composite board, and is used for guiding and limiting the composite board.

[0058] When the composite board is processed, the composite board is passed through the surface of the transmission roller 42 and into the limiting frame 44. When the rotating shaft 22 rotates, it can drive the transmission rod 41 to rotate in the support seat 1 through the connection with the belt 43, so that the transmission rod 41 can drive the transmission roller 42 on its surface to rotate synchronously, so that the transmission roller 42 can drive the composite board to slide in the limiting frame 44 through the connection with the composite board, thereby facilitating the periodic cutting of the cutting machine 11 to the composite board.

[0059] The surfaces of the rotating shaft 22 and the transmission rod 41 are provided with belt pulleys, and the belt 43 can drive the rotating shaft 22 and the transmission rod 41 through the belt pulleys. The surface of the transmission roller 42 can be provided with a rubber pad, which can increase the friction coefficient between the transmission roller 42 and the composite board, thereby facilitating the sliding of the composite board in the limiting frame 44 driven by the transmission roller 42.

[0060] In one embodiment of the present application, as shown in Figure 3 and Figure 4 The dust removal unit 5 comprises:

[0061] The rotating rod 51 is rotatably connected to the support seat 1, and the end portion is provided with a rotating frame 52.

[0062] The first rotating rod 53 is rotatably connected in the rotating frame 52, and the end portion is provided with a support 54, and the support 54 is provided with a plurality of sets of dust removal fans 55.

[0063] In this embodiment, the rotating rod 51 is rotatably connected to the support seat 1, and the end portion is provided with a rotating frame 52. The first rotating rod 53 is rotatably connected in the rotating frame 52, and the end portion is provided with a support 54, and the support 54 is provided with a plurality of sets of dust removal fans 55.

[0064] When the dust removal fan 55 is turned on, when the impeller rotates at high speed, the air in the impeller is also driven to rotate, at this time, the air at the center of the impeller is thrown to the edge of the impeller due to the action of centrifugal force, and a vacuum is formed at the center of the impeller. Therefore, the external air continuously flows into the center of the impeller under the action of pressure difference, so that the fan has the ability to suck air.

[0065] One side of the dust removal fan 55 is connected with a dust collection bag, and the dust removal fan 55 can adsorb the dust generated during the cutting process of the composite board into the dust collection bag during work, so as to adsorb the dust during the cutting process of the composite board.

[0066] The rotating unit 6 is opened, the rotating unit 6 can drive the rotating rod 51 to reciprocate and rotate alternately in the support base 1 through the connection with the rotating rod 51, the rotating rod 51 can drive the rotating frame 52 at the end to rotate in the process of rotating, so that the rotating frame 52 can drive the support 54 to reciprocate and rotate alternately synchronously through the first rotating rod 53, so that the support 54 can drive the plurality of groups of dust removal fans 55 on the surface to reciprocate and rotate alternately, thereby increasing the adsorption range of the dust removal fan 55 to the dust generated in the cutting process of the composite board, and effectively improving the adsorption effect of the dust.

[0067] The dust removal fan 55 in the dust removal unit 5 can also be directly installed on the surface of the rotating frame 52, and the rotating frame 52 can drive the dust removal fan 55 to reciprocate and rotate alternately.

[0068] In an embodiment of the present application, as shown in Figure 3 and Figure 4 The rotating unit 6 comprises:

[0069] The motor 61 is installed on the support base 1.

[0070] The rotating shaft 62 is rotatably connected to the support base 1, and the end is provided with the rotating disc 63.

[0071] The rotating column 64 is eccentrically fixed to the rotating disc 63 and is hinged through the double connecting rod 65 and the rotating rod 51.

[0072] In the embodiment, the motor 61 is installed on the support base 1; the rotating shaft 62 is rotatably connected to the support base 1, and the end is provided with the rotating disc 63; the rotating column 64 is eccentrically fixed to the rotating disc 63 and is hinged through the double connecting rod 65 and the rotating rod 51.

[0073] The motor 61 is opened, the output end of the motor 61 can drive the rotating disc 63 on the surface to rotate through the rotating shaft 62, the rotating disc 63 can drive the rotating column 64 on the surface to rotate synchronously when rotating, so that the rotating column 64 can drive the rotating rod 51 to reciprocate and rotate alternately in the support base 1 through the connection with the double connecting rod 65, the rotating rod 51 can drive the rotating frame 52 at the end to rotate in the process of rotating, the rotating frame 52 can drive the support 54 to reciprocate and rotate alternately synchronously through the first rotating rod 53, so that the support 54 can drive the plurality of groups of dust removal fans 55 on the surface to reciprocate and rotate alternately, thereby increasing the adsorption range of the dust removal fan 55 to the dust generated in the cutting process of the composite board.

[0074] The double connecting rod 65 in the rotating unit 6 can also be replaced by a sliding frame, one end of the sliding frame is fixed on the surface of the rotating rod 51, and the other end of the sliding frame is in sliding connection with the surface of the rotating column 64. When the rotating disc 63 drives the rotating column 64 to rotate, the rotating rod 51 can be driven to alternately rotate in the support base 1 through the connection with the sliding frame.

[0075] In one embodiment of the present application, as shown in the figure, Figure 4 The autorotation unit 7 comprises:

[0076] The L-shaped frame 71 is fixed on the support base 1 and internally rotatably connected with the second rotating rod 72;

[0077] The first helical gear 73 is installed at the end of the second rotating rod 72;

[0078] The second helical gear 74 is installed at the end of the first rotating rod 53 and in meshing connection with the first helical gear 73.

[0079] In this embodiment, the L-shaped frame 71 is fixed on the support base 1 and internally rotatably connected with the second rotating rod 72; the first helical gear 73 is installed at the end of the second rotating rod 72; and the second helical gear 74 is installed at the end of the first rotating rod 53 and in meshing connection with the first helical gear 73.

[0080] When the rotating rod 51 drives the rotating frame 52 at the end thereof to alternately rotate, the rotating frame 52 can drive the second helical gear 74 at the end thereof to synchronously rotate through the first rotating rod 53. Since the second helical gear 74 is always in meshing connection with the first helical gear 73, the second helical gear 74 can drive the first rotating rod 53 to alternately rotate in the rotating frame 52 under the action of the first helical gear 73, so that the first rotating rod 53 can drive the dust removal fan 55 on the surface thereof to synchronously and alternately rotate through the support 54.

[0081] Therefore, the dust removal fan 55 can alternately rotate in the direction of the two shafts (the rotating rod 51 and the first rotating rod 53), greatly increasing the adsorption range of the dust removal fan 55 to the dust generated in the cutting process of the composite board and effectively improving the adsorption effect of the dust.

[0082] The L-shaped frame 71 in the autorotation unit 7 and the support base 1 can be connected by bolts or fixedly and integrally connected, which is not limited herein.

[0083] The working principle of the present application is that when the composite board is processed and cut, the cutting machine 11 and the driving part 21 are turned on, the output end of the driving part 21 can drive the eccentric wheel 23 on its surface to rotate through the rotating shaft 22. The eccentric wheel 23 can drive the inner ring 24 on its surface to slide up and down alternately when rotating, so that the inner ring 24 can drive the outer ring 26 to slide up and down synchronously through the rubber ring 25, and the guide unit 3 can guide and limit the outer ring 26, so that the outer ring 26 can guide and limit the inner ring 24 through the rubber ring 25, so that the inner ring 24, the rubber ring 25 and the outer ring 26 slide up and down alternately as a whole, and the eccentric wheel 23 can rotate inside the inner ring 24. The inner ring 24, the rubber ring 25 and the outer ring 26 can drive the cutting machine 11 to slide synchronously when they slide up and down alternately as a whole, so that the cutting machine 11 can cut the composite board. The rotating shaft 22 can drive the feeding unit 4 to feed the composite board when it rotates, improving the stability of the composite board feeding.

[0084] Turn on the dust removal fan 55, which can adsorb the dust generated in the process of cutting the composite board into the dust bag when working, so as to adsorb the dust in the process of cutting the composite board. Turn on the rotating unit 6, which can drive the rotating rod 51 to rotate reciprocatingly in the support seat 1 through the connection with the rotating rod 51, and the rotating rod 51 can drive the rotating frame 52 at its end to rotate during rotation, so that the rotating frame 52 can drive the support 54 to rotate reciprocatingly synchronously through the first rotating rod 53, so that the support 54 can drive the plurality of dust removal fans 55 on its surface to rotate reciprocatingly, thereby increasing the adsorption range of the dust removal fan 55 to the dust generated in the process of cutting the composite board, and effectively improving the adsorption effect of the dust.

[0085] When the rotating rod 51 drives the rotating frame 52 at its end to rotate alternately, the rotating frame 52 can drive the second bevel gear 74 at its end to rotate synchronously through the first rotating rod 53, and since the second bevel gear 74 is always meshed and connected with the first bevel gear 73, the second bevel gear 74 can drive the first rotating rod 53 to rotate alternately in the rotating frame 52 under the action of the first bevel gear 73, so that the first rotating rod 53 can drive the dust removal fan 55 on its surface to rotate alternately synchronously through the support 54.

[0086] Therefore, the dust removal fan 55 can rotate alternately in the direction of the two shafts (rotating rod 51, first rotating rod 53), greatly increasing the adsorption range of the dust removal fan 55 to the dust generated in the process of cutting the composite board, and effectively improving the adsorption effect of the dust.
