[0050] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0051] Combine the following Figure 1-Figure 6 , the automatic cutting device provided by the embodiment of the utility model is described in detail through specific embodiments and application scenarios.

[0052] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the utility model provides an automatic cutting device, comprising: a conveying platform 1, a telescopic driving member 2, a cutting component 3 and a linkage component 4.

[0053] The conveyor platform 1 is used to convey the sheet material along the conveying direction. The cutting assembly 3 is arranged at the front side of the conveyor platform 1 along the conveying direction. The cutting assembly 3 includes a first cutting knife 31 and a second cutting knife 32. The first cutting knife 31 and the second cutting knife 32 are arranged opposite to each other up and down.

[0054] The linkage assembly 4 is rotatably disposed on the conveying platform 1 , one end of the linkage assembly 4 is connected to the first cutting knife 31 , and the other end of the linkage assembly 4 is connected to the second cutting knife 32 .

[0055] The telescopic driving member 2 is connected to the first cutting knife 31 to drive the first cutting knife 31 to move between the first position and the second position along the vertical direction.

[0056] When the first cutting knife 31 is in the first position, the cutting edge of the first cutting knife 31 and the cutting edge of the second cutting knife 32 are far apart; when the first cutting knife 31 is in the second position, the cutting edge of the first cutting knife 31 and the cutting edge of the second cutting knife 32 are in contact with each other.

[0057] It is understandable that the sheet material shown in this embodiment can be cardboard, plastic board, steel plate, etc., and there is no specific limitation on this.

[0058] The conveying platform 1 may adopt conveying mechanisms such as belt conveyors, chain plate conveyors, etc. that are well known in the art. A correction mechanism may be configured on the conveying platform 1 to correct the position and posture of the sheet material during the conveying process based on the correction mechanism.

[0059] In practical applications, the conveying platform 1 can be controlled to convey the sheet material in a step-by-step manner according to the cutting size of the sheet material, so as to meet the demand for continuous cutting of the sheet material.

[0060] A bracket 102 can be set on the upper side of the conveying platform 1 to realize the installation of the telescopic drive member 2 based on the bracket 102. The bracket 102 can be configured as a gantry frame structure. The output end of the telescopic drive member 2 is set vertically downward and connected to the first cutting knife 31.

[0061] The telescopic drive member 2 may be a hydraulic cylinder or a pneumatic cylinder known in the art. When the structural strength of the sheet material is greater than a preset value, for example, when the sheet material is a steel sheet, the telescopic drive member 2 is configured as a hydraulic cylinder; when the structural strength of the sheet material is less than a preset value, for example, when the sheet material is a cardboard, the telescopic drive member 2 is configured as a pneumatic cylinder.

[0062] At the same time, the first cutting knife 31 and the second cutting knife 32 of the cutting assembly 3 are mirror-imaged relative to the horizontal plane, and the cutting edges of the first cutting knife 31 and the second cutting knife 32 are both beveled, so that when the cutting edges of the first cutting knife 31 and the second cutting knife 32 are in contact, the sheet material can be effectively sheared.

[0063] In addition, driven by the telescopic drive member 2, the first cutting knife 31 will move up and down in the vertical plane. At this time, the linkage assembly 4 is used to transmit the force from the first cutting knife 31, thereby lifting the second cutting knife 32 to move up and down, so that the cutting edge of the first cutting knife 31 and the cutting edge of the second cutting knife 32 are reciprocatingly fitted and separated.

[0064] The linkage assembly 4 may be configured as a crank arm or may be configured to include a plurality of transmission rods connected in sequence, and no specific limitation is made to this.

[0065] For the automatic cutting device shown in this embodiment, by configuring a conveyor table 1, a telescopic driving member 2, a cutting assembly 3 and a linkage assembly 4, when cutting a sheet of material, the sheet of material is conveyed to between the first cutting knife 31 and the second cutting knife 32 of the cutting assembly 3 through the conveyor table 1, and when the telescopic driving member 2 drives the first cutting knife 31 to move downward, the first cutting knife 31 drives the second cutting knife 32 to move upward through the linkage assembly 4 during the movement, until the blade of the first cutting knife 31 and the blade of the second cutting knife 32 are in contact with each other, so as to achieve cutting of the sheet of material; when the telescopic driving member 2 drives the first cutting knife 31 to move downward, the first cutting knife 31 drives the second cutting knife 32 to move upward through the linkage assembly 4, until the blade of the first cutting knife 31 and the blade of the second cutting knife 32 are in contact with each other, so as to achieve cutting of the sheet of material; When moving upward, the first cutting knife 31 drives the second cutting knife 32 to move downward through the linkage assembly 4 during the movement until the blade of the first cutting knife 31 and the blade of the second cutting knife 32 are separated from each other, so that the sheet material can be conveyed forward along the gap between the blade of the first cutting knife 31 and the blade of the second cutting knife 32; as the sheet material is continuously fed and the telescopic drive member 2 drives the first cutting knife 31 to continuously reciprocate between the first position and the second position, the blade of the first cutting knife 31 and the blade of the second cutting knife 32 can be reciprocally fitted and separated, thereby realizing continuous cutting of the sheet material.

[0066] It can be seen from the above that the utility model can realize automatic cutting of sheet materials, reduce labor costs, and ensure cutting efficiency of sheet materials.

[0067] In some embodiments, Figure 1 and Figure 4 As shown, the linkage assembly 4 includes at least one set of linkage units 41 , and each set of linkage units 41 includes a pressure rod 411 , a linkage rod 412 and a support rod 413 .

[0068] One end of the pressure rod 411 is connected to the first cutting knife 31, and the other end is rotatably connected to the first end of the connecting rod 412; the middle part of the connecting rod 412 is rotatably arranged on the front side of the conveying platform 1; the second end of the connecting rod 412 is rotatably connected to one end of the supporting rod 413, and the other end of the supporting rod 413 is connected to the second cutting knife 32.

[0069] It is understandable that the pressure rod 411 is fixedly connected to the first cutting blade 31, the support rod 413 is fixedly connected to the second cutting blade 32, and the middle part of the linkage rod 412 is rotatably sleeved on the rotating shaft 414, and the rotating shaft 414 is fixedly arranged on the front side of the conveying platform 1. Among them, the pressure rod 411 and the support rod 413 can be arranged vertically or inclined, and there is no specific limitation on this.

[0070] When the telescopic driving member 2 drives the first cutting knife 31 to move downward, the first cutting knife 31 drives the pressure rod 411 to move downward, and the pressure rod 411 applies a downward force to the first end of the connecting rod 412, so that the connecting rod 412 rotates counterclockwise relative to the conveyor platform 1, so that the second end of the connecting rod 412 drives the support rod 413 to move upward, and then the support rod 413 drives the second cutting knife 32 to move upward until the blade of the first cutting knife 31 and the blade of the second cutting knife 32 are in contact with each other, so as to achieve cutting of the sheet material.

[0071] When the telescopic driving member 2 drives the first cutting knife 31 to move upward, the first cutting knife 31 drives the pressure rod 411 to move upward, and the pressure rod 411 applies an upward force to the first end of the connecting rod 412, so that the connecting rod 412 rotates clockwise relative to the conveying platform 1, so that the second end of the connecting rod 412 drives the supporting rod 413 to move downward, and then the supporting rod 413 drives the second cutting knife 32 to move downward until the cutting edge of the first cutting knife 31 and the cutting edge of the second cutting knife 32 are separated, so that the sheet material can be conveyed forward along the gap between the cutting edge of the first cutting knife 31 and the cutting edge of the second cutting knife 32.

[0072] In some embodiments, Figure 4 As shown, during the cutting process of the sheet material, in order to prevent the linkage assembly 4 from interfering with the sheet material in the conveying direction, the present embodiment provides a pressure rod 411 and a support rod 413 that extend in the vertical direction respectively.

[0073] The pressing rod 411 is located on the left or right side of the cutting assembly 3 along the width direction of the conveying platform 1 ; the linking rod 412 and the supporting rod 413 are located on the lower side of the cutting assembly 3 .

[0074] Furthermore, in this embodiment, a limiting component 101 is also provided on the front side of the conveying platform 1. The limiting component 101 can be configured as a "U"-shaped seat. The support rod 413 is movably arranged in the limiting component 101 along the vertical direction. The limiting component 101 is used to guide the support rod 413 to stably perform lifting and lowering movements along the vertical direction to ensure the stability of the lifting and lowering of the second cutting knife 32.

[0075] In some embodiments, Figure 1 and Figure 4 As shown, two sets of linkage units 41 are provided, and the two sets of linkage units 41 are axially symmetrically arranged relative to the axial symmetry plane of the conveying platform 1 .

[0076] It is understandable that this embodiment further ensures that the second cutting knife 32 stably performs lifting and lowering movements under the linkage of the linkage assembly 4 by providing two sets of linkage units 41, so as to ensure the cutting quality of the sheet material based on the cooperation between the first cutting knife 31 and the second cutting knife 32.

[0077] In some embodiments, Figure 3 As shown, a limiting structure is provided between the second cutting blade 32 and the conveying platform 1; the limiting structure includes a limiting block 321 and a limiting groove 103, the limiting block 321 is provided on the second cutting blade 32, the limiting groove 103 is provided on the conveying platform 1, and extends in the vertical direction.

[0078] The limiting block 321 is movably disposed in the limiting groove 103 to guide the second cutting knife 32 to perform lifting movement relative to the conveying platform 1 .

[0079] When the limit block 321 abuts against the upper wall of the limit slot 103, the second cutting knife 32 is at the highest position; when the limit block 321 abuts against the lower wall of the limit slot 103, the second cutting knife 32 is at the lowest position.

[0080] It can be understood that during the rising process of the second cutting knife 32, the limit block 321 will rise together with the second cutting knife 32, and based on the sliding cooperation between the limit block 321 and the limit groove 103, the stability of the rising of the second cutting knife 32 is ensured; when the top surface of the limit block 321 abuts against the upper groove wall of the limit groove 103, the second cutting knife 32 cannot continue to rise. At this time, the second cutting knife 32 rises to the highest position, and the cutting edge of the first cutting knife 31 and the cutting edge of the second cutting knife 32 are in contact.

[0081] When the second cutting knife 32 is lowered, the limit block 321 will lower together with the second cutting knife 32, and the stability of the lowering of the second cutting knife 32 is ensured based on the sliding cooperation between the limit block 321 and the limit groove 103; when the bottom surface of the limit block 321 abuts against the lower groove wall of the limit groove 103, the second cutting knife 32 cannot continue to lower. At this time, the second cutting knife 32 is lowered to the lowest position, and the cutting edge of the first cutting knife 31 and the cutting edge of the second cutting knife 32 are separated.

[0082] In this way, based on the cooperation between the limiting block 321 and the limiting groove 103, this embodiment can stably control the blade of the first cutting knife 31 and the blade of the second cutting knife 32 to switch between the fitting state and the separation state.

[0083] In some embodiments, Figure 1 and Figure 2 As shown, the conveying platform 1 includes a conveying platform surface 11 and a clamping assembly 12 .

[0084] The conveying table 11 is used to place the sheet material and convey the sheet material horizontally along its length direction; the clamping assembly 12 is arranged on the upper side of the conveying table 11, and the clamping assembly 12 has a clamping opening, which can be adjusted along the width direction of the conveying table 11.

[0085] The clamping assembly 12 is used to limit the position of the sheet material on the conveying table 11 through the clamping opening.

[0086] It is understandable that the conveying table 11 can be configured as a box body, on which a conveyor belt and a rotating drive mechanism matching the conveyor belt are arranged. The conveyor belt extends along the length direction of the box body and is arranged horizontally to realize horizontal conveyance of the sheet material.

[0087] In practical applications, the clamping width of the clamping mouth of the clamping assembly 12 can be determined according to the width of the sheet to be cut. After the clamping width of the clamping mouth is adjusted, the clamping assembly 12 can be used to limit the position of the sheet on the conveying table 11 to prevent the position of the sheet from changing during the cutting process. Based on the mutual cooperation between the conveying table 1 and the cutting assembly 3, the cutting quality of the sheet is ensured.

[0088] In some embodiments, Figure 2 As shown, the clamping assembly 12 includes a first clamping member 121, a second clamping member 122 and a driving member.

[0089] The first clamping member 121 and the second clamping member 122 are disposed opposite to each other along the width direction of the conveying table 11 , and a clamping opening is formed between the first clamping member 121 and the second clamping member 122 .

[0090] The driving member is connected to the first clamping member 121 and the second clamping member 122 respectively to drive the first clamping member 121 and the second clamping member 122 to move closer to or farther from each other.

[0091] It is understandable that in this embodiment, a driving member can be configured for each of the first clamping member 121 and the second clamping member 122, so that the first clamping member 121 and the second clamping member 122 can be driven by the driving member to move closer to or farther away from each other, thereby adjusting the cutting width of the sheet material.

[0092] Of course, in this embodiment, the first clamping member 121 and the second clamping member 122 can also be connected to the same set of driving members, and the same set of driving members can be used to drive the first clamping member 121 and the second clamping member 122 to move closer or farther away.

[0093] In this application scenario, the driving member can be configured to include a driving motor, a lead screw, a first lead screw nut, a second lead screw nut and a slide rail, wherein the driving motor is connected to the lead screw, a forward thread segment and a reverse thread segment are provided on the lead screw, the first lead screw nut is sleeved on the forward thread segment, and the second lead screw nut is sleeved on the reverse thread segment; the slide rail and the lead screw are arranged side by side, and the first lead screw nut and the second lead screw nut are movably arranged on the slide rail respectively. Among them, the first lead screw nut is connected to the first clamping member 121, and the second lead screw nut is connected to the second clamping member 122.

[0094] In this way, when the driving motor drives the lead screw to rotate clockwise or counterclockwise, the first lead screw nut and the second lead screw nut can approach or move away from each other along the slide rail, thereby conveniently adjusting the clamping width between the first clamping member 121 and the second clamping member 122.

[0095] In some embodiments, Figure 3 and Figure 5 As shown, the first clamping member 121 and the second clamping member 122 are configured to have the same structure, and both the first clamping member 121 and the second clamping member 122 include a plate body 1211 and a slider 1212 .

[0096] The plate body 1211 is extended along the conveying direction of the conveying table 11, and the slider 1212 is arranged on the lower side of the plate body 1211; a slide groove 110 is provided on the conveying table 11, and the slide groove 110 is extended along the width direction of the conveying table 11, and the slider 1212 is movably arranged in the slide groove 110 along the extension direction of the slide groove 110.

[0097] It is understandable that, based on the sliding fit between the slider 1212 and the slide groove 110 , it is possible to ensure that the first clamping member 121 and the second clamping member 122 can stably move along the width direction of the conveying table 11 .

[0098] The slide groove 110 may be configured as a dovetail groove, and the slider 1212 is adapted to the shape of the slide groove 110 to prevent the slider 1212 from being separated from the slide groove 110 when the slider 1212 moves along the slide groove 110 .

[0099] like Figure 1 and Figure 2 As shown, the automatic cutting device shown in this embodiment further includes: a human-computer interaction module 7, a first position sensor and a second position sensor.

[0100] The first position sensor and the second position sensor are electrically connected to the human-machine interaction module 7 , respectively. The human-machine interaction module 7 is electrically connected to the telescopic driving member 2 , the conveying table 11 , and the clamping assembly 12 , respectively.

[0101] The human-computer interaction module 7 is used for the operator to input cutting parameters.

[0102] The first position sensor is used to detect the distance information of the sheet material moving along the conveying direction, and the human-machine interaction module 7 is used to control the conveying state of the conveying table 11 according to the distance information and the cutting parameters.

[0103] The second position sensor is used to detect the position information of the sheet material relative to the conveying table 11 along the width direction, and the human-computer interaction module 7 is used to control the clamping state of the clamping assembly 12 according to the position information and cutting parameters.

[0104] It is understandable that the first position sensor and the second position sensor may both be cameras or infrared ranging sensors known in the art.

[0105] The human-machine interaction module 7 may be a touch screen controller known in the art. The human-machine interaction module 7 is disposed on the support column 6 and located on the conveying platform 1 to facilitate the operator to perform human-machine interaction operations.

[0106] In actual applications, the operator inputs cutting parameters into the human-computer interaction module 7 in advance according to actual needs. The cutting parameters can be the cutting length and cutting width set for the sheet to be cut. The human-computer interaction module 7 responds to the operator's input instructions to control the working status of the telescopic drive 2, the conveying table 11 and the clamping assembly 12, so as to continuously cut the sheet through the cutting assembly 3.

[0107] During sheet material conveying based on the conveyor table 1, the first position sensor detects the distance information of the sheet material moving along the conveying direction in real time. The human-computer interaction module 7 compares the distance information fed back by the first position sensor with the cutting length corresponding to the cutting parameters, and performs PID control on the conveyor table 1 to ensure that the cutting length of the sheet material meets the set requirements.

[0108] Correspondingly, the second position sensor detects in real time the position information of the sheet material along the width direction relative to the conveying table 11. The human-computer interaction module 7 compares the position information fed back by the second position sensor with the cutting width corresponding to the cutting parameters, and performs PID control on the conveying table 1 to ensure that the clamping width of the clamping assembly 12 is adapted to the width of the sheet material, so as to correct the posture of the sheet material during the cutting process based on the clamping assembly 12 to ensure the cutting quality of the sheet material.

[0109] like Figure 1 and Figure 6 As shown, the automatic cutting device shown in this embodiment also includes: a collecting box 5; the collecting box 5 is arranged on the front side of the conveying platform 1 along the conveying direction, and the collecting box 5 is used to collect the sheet materials after the cutting process by the cutting component 3.
