[0052] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0053] like Figures 1 to 5 As shown, a material receiving mechanism 100 provided by one embodiment of the present invention includes a support base 1, a conveying assembly 2, and a material digging assembly 3. The conveying assembly 2 is rotatably connected to the support base 1, and the material digging assembly 3 is mounted on the support base 1. The material digging assembly 3 includes a mounting base 31, a first driving member 32, and a material digging member 33. The first driving member 32 is mounted on the mounting base 31, and the output end of the first driving member 32 is connected to the material digging member 33.

[0054] The conveyor assembly 2 is used to move the sheet material in a first direction a toward or away from the material bin 300. The sheet material contacts the conveyor assembly 2, and when the conveyor assembly 2 rotates, the sheet material is moved. When the sheet material moves to a predetermined position, the conveyor assembly 2 stops rotating, and the first driving member 32 drives the material shifting member 33 to rotate, so that the material shifting member 33 can shift the sheet material to continue moving in the first direction a. The material shifting member 33 provides additional thrust to the sheet material, thereby storing the sheet material in the material bin 300 or delivering the sheet material out of the material bin 300.

[0055] Among them, the preset position is the maximum distance that the conveying component 2 can drive the material sheet to move. For example, when the material sheet is stored in the material box 300, after the conveying component 2 drives most of the material sheet into the material box 300, the remaining small part does not run smoothly. In this case, during the rotation of the material shifting member 33, a thrust can be applied to the material sheet, and the material sheet can be pushed into the material box 300 to avoid affecting the storage of the material sheet.

[0056] Specifically, the support base 1 is disposed on one side of the material bin 300 and is capable of driving the material sheets in and out of the material bin 300 via the material receiving mechanism 100. When the material sheets need to be stored in the material bin 300, the material sheets from the previous process are delivered to the material bin 300. The conveying assembly 2 rotates, thereby driving the material sheets to move in the first direction a, allowing the material sheets to gradually enter the material bin 300. When the material sheets reach the preset position, most of the material sheets have entered the material bin 300, and the conveying assembly 2 stops conveying. Next, the first driving member 32 drives the material diverter 33 to rotate. During the rotation process, the material diverter 33 can abut the material sheets and push the material sheets to continue moving in the first direction a, thereby allowing the material sheets to completely enter the material bin 300. When the sheet material is delivered from the bin 300, the pushing mechanism provided on the bin 300 pushes the sheet material. After the sheet material contacts the conveyor assembly 2, the conveyor assembly 2 drives the sheet material to move, further increasing the driving force of the sheet material. When the sheet material reaches the preset position, most of the sheet material has been moved out of the bin 300, at which point the conveyor assembly 2 stops conveying. The first driving member 32 drives the material shifting member 33 to rotate. During the rotation process, the material shifting member 33 can abut against the sheet material and push the sheet material to continue moving in the first direction a, thereby completely delivering the sheet material from the bin 300.

[0057] In this embodiment, after the material sheet is moved a certain distance to a preset position by the conveying component 2, most of the material sheet enters or leaves the material box 300, and a small part of the material sheet still has not entered or left the material box 300. The first driving component 32 drives the material shifting component 33 to rotate, so that the material shifting component 33 applies a thrust on the material sheet during the rotation process, thereby pushing the remaining part of the material sheet into or out of the material box 300, avoiding insufficient conveying force of the conveying component 2 and affecting the input or output of the material sheet.

[0058] In one embodiment, the first driving member 32 is a motor.

[0059] In one embodiment, if Figure 4 As shown, the material-digging member 33 includes a connecting rod 331 and a first material-digging portion 332. The first material-digging portion 332 extends along the second direction. One end of the connecting rod 331 is connected to the output end of the first driving member 32, and the other end of the connecting rod 331 is connected to one end of the first material-digging portion 332. The other end of the first material-digging portion 332 is connected to the second material-digging portion 333. The first direction a and the second direction b are not parallel and do not overlap.

[0060] When the first driving member 32 drives the connecting rod 331 to rotate, the other end of the first material-moving portion 332 can rotate about the central axis of the connecting rod 331 to move the material sheet. When the connecting rod 331 rotates, the first material-moving portion 332 swings within a range centered on the central axis of the connecting rod 331. As the first material-moving portion 332 swings, it can contact the material sheet and apply a thrust, thereby pushing the material sheet to move in the first direction a. This provides additional thrust to the material sheet when the conveying assembly 2 is unable to convey the material sheet or when the material sheet is not moving smoothly, thereby ensuring the movement of the material sheet.

[0061] In one embodiment, the material-pickup member 33 also includes a second material-pickup portion 333, and the end of the first material-pickup portion 332 away from the connecting rod 331 is connected to the second material-pickup portion 333. The second material-pickup portion 333 and the connecting rod 331 are offset in the second direction b. When the first driving member 32 drives the connecting rod 331 to rotate, it can drive the first material-pickup portion 332 and the second material-pickup portion 333 to rotate.

[0062] Since the first material-prying portion 332 is connected between the second material-prying portion 333 and the connecting rod 331, and the second material-prying portion 333 and the connecting rod 331 are misaligned in the second direction b, when the connecting rod 331 rotates, the first material-prying portion 332 swings within a range centered on the central axis of the connecting rod 331, and the second material-prying portion 333 swings along with the first material-prying portion 332, and can contact the material plate and apply thrust, thereby pushing the material plate to move along the first direction a.

[0063] Preferably, the first direction a and the second direction b are perpendicular, and the first material-dividing portion 332 swings within a plane defined by the first direction a and the second direction b. The first material-dividing portion 332 extends along the second direction b. The connecting rod 331 is connected to one end of the first material-dividing portion 332 and extends along the first direction a toward the mounting seat 31. The second material-dividing portion 333 is rotatably connected to the other end of the first material-dividing portion 332. The second material-dividing portion 333 is cylindrical and extends along the first direction a away from the mounting seat 31, ensuring that the second material-dividing portion 333 can contact the material sheet when the connecting rod 331 rotates.

[0064] In one embodiment, if Figure 2 、 Figure 4 As shown, the mounting base 31 includes a first mounting plate 311, a second mounting plate 312, and a plurality of struts 313. The first mounting plate 311 is further away from the support base 1 than the second mounting plate 312, and is located above the second mounting plate 312. The plurality of struts 313 are spaced apart and connected between the first mounting plate 311 and the second mounting plate 312 to form a support structure. The first driving member 32 is mounted on the first mounting plate 311, and one end of the connecting rod 331 passes through the second mounting plate 312 and is connected to the output end of the first driving member 32.

[0065] In one embodiment, if Figure 4 As shown, a first sensing piece 34 is provided on the material-digging member 33, and a first sensor 35 and a second sensor 36 are provided on the mounting base 31. The first driving member 32 can drive the material-digging member 33 to rotate between a first position and a second position. When the material-digging member 33 is in the first position, the first sensor 35 can sense the first sensing piece 34. When the material-digging member 33 is in the second position, the second sensor 36 can sense the first sensing piece 34. By having the first sensor 35 and the second sensor 36 respectively sense the first sensing piece 34, the rotation range of the material-digging member 33 can be limited, which helps the material-digging member 33 push the material plate and prevents the material-digging member 33 from colliding with other components.

[0066] The first sensor 35 and the second sensor 36 are mounted on the first mounting plate 311, and the first sensing piece 34 is mounted on the connecting rod 331. When the connecting rod 331 rotates, the first sensing piece 34 can trigger the first sensor 35 and the second sensor 36. Before the material is shifted, the first sensing piece 34 and the first sensor 35 trigger each other. When the material is shifted, the first driving member 32 drives the shifting member 33 to rotate, and the first sensing piece 34 rotates with the shifting member 33. When the first sensing piece 34 triggers the second sensor 36, the first driving member 32 stops driving. At this time, the second shifting portion 333 has a displacement in the first direction a. The second shifting portion 333 applies a thrust to the material plate, which can push the material plate to move in the first direction a.

[0067] In one embodiment, if Figure 2、 Figure 4 As shown, the material diverter assembly 3 also includes a transmission assembly 37 installed on the mounting base 31. The transmission assembly 37 is installed between the first mounting plate 311 and the second mounting plate 312. The material diverter 33 includes a first material diverter 33a and a second material diverter 33b. The input end of the transmission assembly 37 is connected to the output end of the first driving member 32, and the output end of the transmission assembly 37 is connected to the first material diverter 33a and the second material diverter 33b. The first driving member 32 can drive the first material diverter 33a and the second material diverter 33b to rotate. The first driving member 32 can simultaneously drive the first material diverter 33a and the second material diverter 33b to rotate through the transmission assembly 37, so that the first material diverter 33a and the second material diverter 33b remain synchronized. In the process of pushing the material sheet into the material box 300, the first material diverter 33a and the second material diverter 33b simultaneously apply thrust to the material sheet, and can apply uniform thrust from different positions, so that the material sheet can smoothly enter the material box 300 and avoid jamming or tilting. The first sensing piece 34 is disposed on the first material-moving member 33 a . When the first sensing piece 34 triggers the second sensor 36 , the first material-moving member 33 a and the second material-moving member 33 b rotate to their proper positions, and the first driving member 32 stops driving.

[0068] The first material diverter 33a rotates in the opposite direction to the second material diverter 33b. That is, when the first material diverter 33a rotates clockwise, the second material diverter 33b rotates counterclockwise. When the first material diverter 33a rotates counterclockwise, the second material diverter 33b rotates clockwise. In this way, during the rotation of the first and second material diverters 33a, 33b, there is no interference with the components between the first and second material diverters 33a, 33b.

[0069] In one embodiment, if Figure 4 As shown, the transmission assembly 37 includes a driving wheel 371, a transition wheel 372, a first driven wheel 373, and a second driven wheel 374. The driving wheel 371 is connected to the output end of the first driving member 32, and the first driven wheel 373 is mounted on the connecting rod 331 of the first material-diverting member 33a and meshes with the driving wheel 371. Through the meshing of the first driven wheel 373 and the driving wheel 371, power can be stably transmitted from the first driving member 32 to the first material-diverting member 33a, thereby achieving rotation of the first material-diverting member 33a.

[0070] The second driven wheel 374 is installed on the second material diverter 33b and meshes with the transition wheel 372, and the transition wheel 372 meshes with the driving wheel 371, that is, the second driven wheel 374, the transition wheel 372 and the driving wheel 371 mesh in sequence, and the transition wheel 372 plays the role of transmitting power and changing the transmission direction. When the first material diverter 33a and the second material diverter 33b need to rotate in opposite directions, the transition wheel 372 is set between the second driven wheel 374 and the driving wheel 371, which can change the rotation direction of the second material diverter 33b, so that the rotation direction of the second material diverter 33b is different from the rotation direction of the first material diverter 33a.

[0071] In one embodiment, if Figure 2 、 Figure 3 As shown, the material receiving mechanism 100 also includes a second driving member 5, which is installed on the support seat 1, and the output end of the second driving member 5 is connected to the second mounting plate 312. The second driving member 5 can drive the material picking assembly 3 to reciprocate between the first position and the second position along the third direction c; the first direction a and the third direction c are not parallel and do not overlap.

[0072] The third direction c is Figure 2 In the vertical direction, the first position is above the second position. The second driving member 5 drives the material-dividing assembly 3 to move upward. When the material-dividing assembly 3 is in the first position, there is a gap between the end of the material-dividing member 33 close to the conveying assembly 2 and the conveying assembly 2, which can avoid the material sheet and facilitate the conveying assembly 2 to drive the material sheet to the preset position. After the material sheet reaches the preset position, the second driving member 5 drives the material-dividing assembly 3 downward, and the material-dividing assembly 3 moves from the first position to the second position. When the material-dividing assembly 3 is in the second position, the first driving member 32 drives the material-dividing member 33 to rotate, so that the material-dividing member 33 can push the material sheet to move.

[0073] Further, if Figure 4 As shown, the material-moving member 33 has three positions during rotation: a zero position, a first rotational position, and a second rotational position. The first sensor 35 and the second sensor 36 are arranged opposite each other in the first direction a. When the material-moving assembly 3 is in the first position, the material-moving member 33 is at the zero position, and the first sensor plate 34 is located between the first sensor 35 and the second sensor 36. At this time, the second material-moving portion 333 is located above the material plate.

[0074] When the material sheet reaches the preset position, the second driving member 5 drives the material diverter assembly 3 to move downward, and the first driving member 32 drives the first diverter member 33a and the second diverter member 33b to rotate outward from the zero position. When the first sensing plate 34 triggers the first sensor 35, the first sensor 35 receives the in-position signal and the first driving member 32 stops. At this time, the second diverter portion 333 of the first diverter member 33a and the second diverter portion 333 of the second diverter member 33b swing outward, avoiding the material sheet in the vertical direction. When the second driving member 5 drives the material diverter assembly 3 to continue to move downward, the second diverter portion 333 of the first diverter member 33a and the second diverter portion 333 of the second diverter member 33b will not collide with the material sheet. After moving downward into position, the first driving member 32 drives the first diverter member 33a and the second diverter member 33b to rotate, and the first diverter member 33a and the second diverter member 33b can push the material sheet to move until the first sensing plate 34 triggers the second sensor 36, at which time the first driving member 32 stops. Finally, the second driving member 5 drives the material shifting assembly 3 back to the initial position, and the first driving member 32 drives the first material shifting member 33a and the second material shifting member 33b to rotate back to the zero position, so as to facilitate the next material plate conveying.

[0075] In one embodiment, if Figure 1 、 Figure 2 As shown, the material receiving mechanism 100 also includes a material pressing assembly 4, which is connected to the mounting seat 31. When the second driving member 5 drives the material shifting assembly 3 to move up and down along the third direction c, it can drive the material pressing assembly 4 to move back and forth along the third direction c through the mounting seat 31.

[0076] As the press assembly 4 moves downward, it gradually approaches the conveyor assembly 2, thereby pressing the sheet material between the press assembly 4 and the conveyor assembly 2. The press assembly 4 is used to apply pressure to the sheet material to increase the friction between the sheet material and the conveyor assembly 2 when the conveyor assembly 2 drives the sheet material to move. When there is sufficient friction between the sheet material and the conveyor assembly 2, the power of the conveyor assembly 2 can be effectively transmitted to the sheet material, and the sheet material can better "attach" to the conveyor assembly 2, thereby moving stably with the movement of the conveyor assembly 2, reducing the possibility of slippage and deviation.

[0077] In one embodiment, if Figure 1 As shown, a third sensor 14 and a fourth sensor 15 are provided on the support base 1 , and the third sensor 14 is located above the fourth sensor 15 in the third direction c.

[0078] A second sensing sheet 421 is provided on the pressing assembly 4, and the second sensing sheet 421 can trigger the third sensor 14 or the fourth sensor 15. The third sensor 14 is an extreme position sensor, which can limit the highest position of the pressing assembly 4 to move upward. The fourth sensor 15 is an initial position sensor, which can limit the initial position of the pressing assembly 4.

[0079] like Figure 2 As shown, when the second sensing piece 421 triggers the fourth sensor 15, the pressing assembly 4 is located at the initial position. When the conveying assembly 2 starts to convey the material sheet, the second driving member 5 drives the pressing assembly 4 to descend until the pressing assembly 4 squeezes the material sheet.

[0080] When the sheet reaches the preset position, Figure 3 As shown, the second driving member 5 drives the material-prying assembly 3 to move downward while driving the material-pressing assembly 4 to move upward. The first driving member 32 drives the material-prying member 33 to rotate. When the first sensing piece 34 triggers the first sensor 35, the first sensor 35 receives the in-position signal and the first driving member 32 stops. The second driving member 5 drives the material-prying assembly 3 to continue to move downward, and the material-pressing assembly 4 to continue to move upward. When the second sensing piece 421 triggers the third sensor 14, they stop moving. The material-prying assembly 3 and the material-pressing assembly 4 move into position. Then, the first driving member 32 drives the material-prying member 33 to pry the material.

[0081] In one embodiment, if Figure 1 As shown, the material receiving mechanism 100 also includes a support rod 61 and a connecting rod 62. The support rod 61 is installed on the support seat 1. The middle part of the connecting rod is rotatably connected to the support rod 61. One end of the connecting rod 62 is rotatably connected to the pressing assembly 4, and the other end of the connecting rod 62 is rotatably connected to the mounting seat 31.

[0082] like Figure 2 、 Figure 3 As shown, with the support rod 61 as the fulcrum, the connecting rod 62 rotates relative to the support rod 61, driving the pressing assembly 4 and the prying assembly 3 to move in opposite directions in the third direction c. When the second driving member 5 drives the prying assembly 3 upward toward the first position, the connecting rod 62 drives the pressing assembly 4 downward along the third direction c. This allows the prying assembly 3 to avoid the material sheet while also enabling the pressing assembly 4 to squeeze the material sheet.

[0083] When the sheet material reaches the preset position, the second driving member 5 drives the material shifting assembly 3 to move downward toward the second position, and the pressing assembly 4 moves upward along the third direction C through the transmission of the connecting rod 62. This allows the pressing assembly 4 to separate from the sheet material and no longer apply pressure to the sheet material. At the same time, after the material shifting assembly 3 moves downward into position, the first driving member 32 can drive the material shifting member 33 to rotate and shift the sheet material.

[0084] In this embodiment, the connecting rod 62 is connected between the mounting base 31 of the pressing assembly 4 and the material shifting assembly 3, so that the synchronous reverse movement of the pressing assembly 4 and the material shifting assembly 3 can be achieved, thereby reducing the operation time of the material receiving mechanism 100, and the pressing assembly 4 and the material shifting assembly 3 can share the second driving member 5, thereby reducing the number of components.

[0085] In one embodiment, if Figure 2 As shown, there are two pressing assemblies 4, namely the first pressing assembly and the second pressing assembly, which are arranged on both sides of the prying assembly 3 in the second direction b. Correspondingly, there are two connecting rods 62, namely the first connecting rod and the second connecting rod. One end of the mounting seat 31 is connected to the first pressing assembly through the first connecting rod, and the other end of the mounting seat 31 is connected to the second pressing assembly through the second connecting rod. When the second driving member 5 drives the prying assembly 3 to move upward, the first pressing assembly and the second pressing assembly move downward synchronously. When the second driving member 5 drives the prying assembly 3 to move downward, the first pressing assembly and the second pressing assembly move upward synchronously.

[0086] In one embodiment, if Figure 2 、 Figure 5 As shown, the pressing assembly 4 includes a first pressing wheel 41, a pressing wheel mounting frame 42, and a connecting member 43. The first pressing wheel 41 is mounted on the pressing wheel mounting frame 42, and the second sensing plate 421 is mounted on the pressing wheel mounting frame 42. The first pressing wheel 41 is used to press the sheet material when the conveyor assembly 2 drives the sheet material to move, thereby increasing the friction between the sheet material and the conveyor assembly 2. The first pressing wheel 41 is rotatably connected to the pressing wheel mounting frame 42. The rolling characteristics of the first pressing wheel 41 ensure that it does not cause excessive wear or scratches on the surface of the sheet material while pressing the sheet material.

[0087] One end of the connecting member 43 is connected to the pressure wheel mounting frame 42, and the other end of the connecting member 43 is rotatably connected to the connecting rod 62. The connection between the pressing assembly 4 and the connecting rod 62 can be realized through the connecting member 43, so that under the drive of the second driving member 5, the up and down movement of the pressing assembly 4 can be realized through the connection between the connecting rod 62 and the connecting member 43.

[0088] In one embodiment, if Figure 5 As shown, the pressing assembly 4 further includes an adapter 45 and an elastic member 46. The adapter 45 is mounted on the pressure roller mounting frame 42, and an accommodating cavity 453 is formed in the adapter 45. A limiting member 44 is provided at one end of the connecting member 43 close to the pressure roller mounting frame 42. In the third direction c, the projected area of ​​the limiting member 44 is larger than the projected area of ​​the connecting member 43. The limiting member 44 protrudes from the connecting member 43 in the circumferential direction of the connecting member 43. Accommodating the limiting member 44 in the accommodating cavity 453 can effectively limit the position of the connecting member 43 in the third direction c, so that it cannot be separated from the accommodating cavity 453, thereby achieving the connection between the connecting member 43 and the pressure roller mounting frame 42.

[0089] The elastic member 46 is disposed in the accommodating cavity 453 and abuts between the limiting member 44 and the pressure roller mounting bracket 42. The second driving member 5 can drive the connecting member 43 to squeeze the elastic member 46, so that the elastic member 46 generates an elastic force applied to the sheet. The elastic force generated by the compression of the elastic member 46 is transmitted to the pressure roller mounting bracket 42, and then applied to the sheet through the first pressure roller 41, so that the pressing assembly 4 can automatically adjust the pressure according to the different conditions of the sheet. In addition, during the pressing process, the elastic member 46 can act as a buffer, reducing the impact between the first pressure roller 41 and the sheet, and protecting the sheet from excessive pressure shock.

[0090] When the second driving member 5 drives the material-prying assembly 3 to move upward, the connecting rod 62 is connected to the support rod 61 through rotation, so that the pressing assembly 4 can move downward. When the first pressing wheel 41 contacts the material plate, the pressing wheel mounting bracket 42 no longer moves downward. Then, the second driving member 5 continues to drive the material-prying assembly 3 to move upward. At this time, through the connection between the connecting rod 62 and the connecting member 43, the connecting member 43 can be driven to continue to move downward, so that the elastic member 46 is compressed, and the elastic member 46 generates an elastic force, which is applied to the material plate through the pressing wheel mounting bracket 42, thereby squeezing the material plate and increasing the friction between the material plate and the conveying assembly 2.

[0091] In one embodiment, the elastic member 46 is a compression spring.

[0092] In one embodiment, if Figure 5 As shown, the adapter seat 45 includes a first adapter 451 and a second adapter 452. The first adapter 451 and the second adapter 452 are both in an inverted L shape and are arranged opposite to each other. A accommodating cavity 453 is formed between the first adapter 451 and the second adapter 452. There is an opening between the two that is connected to the accommodating cavity 453. The width of the opening is close to the outer diameter of the connecting member 43. The limit member 44 is located between the first adapter 451 and the second adapter 452. The end of the connecting member 43 close to the pressure roller mounting frame 42 can extend into the accommodating cavity 453 through the opening and be connected to the limit member 44. The first adapter 451 and the second adapter 452 can stop the limit member 44 from detaching from the accommodating cavity 453.

[0093] In one embodiment, if Figure 5 As shown, the pressing assembly 4 further includes a third sensing piece 441 and a fifth sensor 48. The third sensing piece 441 is mounted on the limiting member 44, and the fifth sensor 48 is mounted on the adapter 45. Driven by the second driving member 5, the connecting member 43 can continuously move downward and compress the elastic member 46. When the third sensing piece 441 triggers the fifth sensor 48, the second driving member 5 stops driving the connecting member 43. The third sensing piece 441 and the fifth sensor 48 can limit the movement range of the connecting member 43, preventing the connecting member 43 from excessively compressing the elastic member 46, thereby avoiding excessive pressure on the sheet material.

[0094] Specifically, when the second sensing piece 421 triggers the fourth sensor 15, the pressing assembly 4 is located at the initial position. When the conveying assembly 2 starts to convey the material plate, the second driving member 5 drives the pressing assembly 4 to descend until the third sensing piece 441 triggers the fifth sensor 48, and the pressing assembly 4 stops moving downward.

[0095] In one embodiment, if Figure 2 、 Figure 5 As shown, the pressing assembly 4 further includes a plurality of guide shafts 47, which are spaced apart on the pressing roller mounting frame 42. One end of each guide shaft 47 is connected to the pressing roller mounting frame 42, and the other end of each guide shaft 47 is slidably connected to the support base 1. The plurality of guide shafts 47 can guide the movement of the pressing assembly 4, ensuring the accuracy of the pressing direction and preventing the pressing roller mounting frame 42 from deviating or shaking during movement, which may cause the first pressing roller 41 to be unable to uniformly press the material sheet and affect the pressing effect.

[0096] Among them, a linear bearing is provided on the support seat 1 , and the guide shaft 47 is fitted in the linear bearing to achieve the sliding of the guide shaft 47 relative to the support seat 1 .

[0097] In one embodiment, if Figure 1 As shown, the support base 1 includes a first support plate 11, a second support plate 12 and a plurality of connecting plates 13, and the plurality of connecting plates 13 are connected between the first support plate 11 and the second support plate 12.

[0098] like Figure 5 As shown, the multiple guide shafts 47 include at least a first guide shaft 471 and a second guide shaft 472. The end of the first guide shaft 471 away from the pressure roller mounting frame 42 is inserted through the first support plate 11, and the end of the second guide shaft 472 away from the pressure roller mounting frame 42 passes through the first support plate 11 and is slidably engaged with the mounting base 31. The first guide shaft 471 and the second guide shaft 472 are arranged at both ends of the pressure roller mounting frame 42 to ensure the stability of the movement of the pressure roller mounting frame 42 during the up and down movement.

[0099] Among them, a linear bearing is provided on the mounting seat 31, and the second guide shaft 472 is passed through the linear bearing to achieve sliding fit. When the second driving member 5 drives the material-picking assembly 3 to move up and down, the mounting seat 31 can move along the second guide shaft 472, and the second guide shaft 472 can provide guidance for the operation of the material-picking assembly 3.

[0100] Furthermore, two pressing assemblies 4 are provided, namely a first pressing assembly and a second pressing assembly, which are arranged on both sides of the prying assembly 3 in the second direction b.

The output end of the third driving member 21 is connected to the second pressure roller 22. The third driving member 21 is used to drive the second pressure roller 22 to rotate, thereby driving the sheet material to move in the first direction a. The third driving member 21 directly transmits power to the second pressure roller 22, thereby achieving efficient conveyance of the sheet material.

[0102] In one embodiment, a plurality of second pressure wheels 22 are provided, and the plurality of second pressure wheels 22 are connected via couplings and connecting shafts. Driven by the third driving member 21 , the plurality of second pressure wheels 22 rotate synchronously.

[0103] Preferably, there are two pressing assemblies 4, namely the first pressing assembly and the second pressing assembly, and there are two second pressing wheels 22. The first pressing wheel 41 of the first pressing assembly and one of the second pressing wheels 22 work together to convey the material plate, and the first pressing wheel 41 of the second pressing assembly and the other second pressing wheel 22 work together to convey the material plate.

[0104] In one embodiment, if Figure 1 As shown, a receiving sensor 16 and a discharging sensor 17 are provided on the support seat 1, and the receiving sensor 16 and the discharging sensor 17 are installed on the second support plate 12. The receiving sensor 16 is used to limit the preset position of the material sheet when the material sheet moves along the first direction a toward the material box 300, and the discharging sensor 17 is used to limit the preset position of the material sheet when the material sheet moves along the first direction a away from the material box 300, so that the position of the material sheet can be accurately controlled during receiving and discharging.

[0105] Specifically, when receiving materials, the conveying component 2 drives the material sheet into the material box 300, and the material receiving sensor 16 can continuously monitor the material sheet. When the material receiving sensor 16 cannot sense the material sheet, it indicates that the material sheet has passed the material receiving sensor 16 in the first direction a, and the material sheet has reached the preset position of the material receiving operation, and the material shifting action can be started.
