Description

Technical Field

[0001] The present application relates to the field of automatic deviation-correcting material folding equipment, and in particular to an automatic deviation-correcting material folding equipment. Background Art

[0002] In the process of making envelope bags, one of the steps requires folding both sides of the raw material 01. Specifically, both sides of the raw material 01 are folded along the preset folding line 013 toward the preset virtual center line 011, so that the two sides of the raw material 01 are folded to form a folded piece 012. The edge of the folded piece 012 close to the preset virtual center line 011 is the inner edge of the fold 0121, and the edge away from the preset virtual center line 011 is the outer edge of the fold 0122. There is a gap between the inner edges of the fold 0121 on the folding pieces 012 on both sides and the preset virtual center line 011, so that the raw material 01 can be cut along the virtual center line 011 in the subsequent steps.

[0003] During the operation, the raw material 01 is usually in the form of a roll. During the process of peeling the raw material 01 from the roll, since the raw material 01 is flexible, although the previous process folds both sides of the raw material 01, during the folding process, the actual folding line 013 may deviate from the preset folding line 013.

[0004] In order to make the raw material 01 continue to fold along the preset folding line 013, the position of the raw material 01 needs to be adjusted. At present, the raw material 01 is manually moved by the on-site workers, but this method requires manual input and is relatively inconvenient to operate. Therefore, providing a device that automatically adjusts the raw material until the actual folding line coincides with the preset folding line is an urgent problem to be solved. Summary of the Invention

[0005] In order to automatically adjust the raw material so that the actual folding line coincides with the preset folding line, the present application provides an automatic deviation-correcting folding device.

[0006] The present application provides an automatic deviation-correcting folding device that adopts the following technical solution: A material folding device with automatic deviation correction includes a folding mechanism, a deviation measuring mechanism and a deviation correction mechanism, wherein the deviation correction mechanism is located at the material inlet end of the folding mechanism; the deviation measuring mechanism includes: a first mounting frame connected to the folding mechanism; and Two detection components are provided on both sides of a preset virtual center line, and the detection components are provided on both sides of the preset virtual center line. The detection components include: A detection seat connected to the first mounting frame; a groove is formed on a side of the detection seat away from a preset virtual center line, the groove being used to accommodate an inner edge of a folded leaf of the folding sheet; an infrared emitter, the infrared emitter being fixedly connected to the detection base; An infrared receiver, the infrared receiver is fixedly connected to the detection base; on the upper and lower sides of the groove, one side is provided with the infrared transmitter, and the other side is provided with the infrared receiver, the infrared receiver is used to receive the light beam emitted by the infrared transmitter; and A processor is communicatively connected to the infrared transmitter and the infrared receiver, and the processor is communicatively connected to the deviation correction mechanism to control the deviation correction mechanism to perform deviation correction.

[0007] By adopting the above technical solution, the light beam emitted by the infrared transmitter is located on the side of the flipped folding sheet. The light beam emitted by the infrared transmitter is blocked by the folding sheet, resulting in the light beam being unable to be received by the infrared receiver, which proves that the raw material is offset. The processor then controls the correction mechanism to operate after receiving the signal; the detection component of the deviation measuring mechanism is used to detect the inner edge of the folding sheet to determine whether the raw material is offset. The processor controls the correction mechanism to correct the offset based on the detection result, so that the actual folding line of the raw material can coincide with the preset folding line, thereby realizing the automatic correction function and improving production efficiency and product quality.

[0008] Optionally, it further includes a material guide plate, wherein the material guide plate and the folding mechanism are arranged in sequence in the feeding direction; two correcting mechanisms are provided, and the correcting mechanisms are arranged on the material guide plate; the correcting mechanisms include a main correcting component and an adjusting component; The main correction component includes: an upper wheel seat, the upper wheel seat being located above the guide plate; and an upper deflection correcting wheel, the upper deflection correcting wheel being rotatably connected to the upper wheel seat about a first axis; the first axis being parallel to the upper plate surface of the guide plate, and the angle formed between the first axis and a preset virtual center line is not equal to 90°; in the two deflection correcting mechanisms, the two upper deflection correcting wheels are symmetrically arranged about the preset virtual center line; The adjustment component includes: a second mounting frame, the second mounting frame being fixedly connected to the material guide plate; a connecting rod, the connecting rod being rotatably connected to the second mounting frame about a second axis, the second axis being arranged horizontally and perpendicular to a preset virtual center line; the upper wheel seat being connected to the connecting rod; and a first motor, the first motor being in communication with the processor; the first motor being connected between the connecting rod and the second mounting frame, and configured to drive the connecting rod to rotate about a second axis, so as to adjust the upper deflection-correcting wheel between a deflection-correcting posture and a withdrawal posture; When the upper deflection-correcting wheel is in the deflection-correcting posture, the upper deflection-correcting wheel is used to press the raw material onto the guide plate; During the process of adjusting the upper deflection-correcting wheel from the deflection-correcting posture to the withdrawing posture, the distance between the upper deflection-correcting wheel and the material guide plate increases.

[0009] By adopting the above technical solution, after the first motor receives the signal from the processor, it drives the connecting rod to rotate to press the upper correcting wheel onto the raw material on the guide plate. Since the upper correcting wheel is inclined, the raw material can be automatically adjusted as the upper correcting wheel rotates.

[0010] Optionally, the main correction component further includes: A second motor is connected between the upper wheel seat and the upper deflection correcting wheel to drive the upper deflection correcting wheel to rotate along the upper wheel seat.

[0011] By adopting the above technical solution, the upper correction wheel is driven by the second motor to rotate along the upper wheel seat, which can push the raw material forward and sideways at the same time, ensuring that the center line of the raw material is at the preset virtual center line, and ensuring that the subsequent actual folding line coincides with the preset folding line.

[0012] Optionally, the main correction component further includes: a first ball seat, the first ball seat being fixedly connected to the upper wheel seat; a first universal ball, the first universal ball being fixedly connected to an end of the connecting rod away from the first motor, and the first universal ball being universally hinged to the first ball seat; and A first locking member is connected between the first ball seat and the first universal ball to fix the first universal ball to the first ball seat.

[0013] By adopting the above technical solution, the arrangement of the first ball seat, the first universal ball and the first locking piece can conveniently adjust the angle of the upper correcting wheel. After adjustment, the first universal ball can also be fixed to ensure stable operation of the upper correcting wheel.

[0014] Optionally, the wheel surface coaxial fixing sleeve of the upper deviation-correcting wheel is provided with a flexible rubber ring.

[0015] By adopting the above technical solution, the wheel surface of the upper deflection correcting wheel is coaxially fixed with a flexible rubber ring, which can make it easier for the upper deflection correcting wheel to push the raw material to move after contacting the raw material.

[0016] Optionally, the correction mechanism further includes an auxiliary correction component, and the auxiliary correction component includes: A lower wheel seat, the lower wheel seat being located below the material guide plate; a linear drive member connected between the lower wheel seat and the material guide plate to drive the lower wheel seat to move; a driving direction of the linear drive member is perpendicular to the upper plate surface of the material guide plate; and A lower deflection correcting wheel is provided below each of the upper deflection correcting wheels; the lower deflection correcting wheel is connected to the lower wheel seat and rotates around the third axis. In the same deflection correcting mechanism, the second axis and the third axis are parallel. An avoidance hole is formed through the material guide plate. Under the drive of the linear drive component, the lower deflection correcting wheel can pass through the avoidance hole and abut against the upper deflection correcting wheel.

[0017] By adopting the above technical solution, the linear drive component in the auxiliary correction component can drive the lower wheel seat to move, so that the lower correction wheel passes through the avoidance hole of the guide plate and abuts against the upper correction wheel, thereby clamping and pushing the raw material, and improving the accuracy and stability of the raw material position adjustment.

[0018] Optionally, the auxiliary correction component further includes: A lifting seat connected to the output end of the linear drive member; a second ball seat, the second ball seat being fixedly connected to the lifting seat; a second universal ball, the second universal ball being hinged to the second ball seat, and the lower wheel seat being fixedly connected to the second universal ball; and A second locking member is connected between the second ball seat and the second universal ball to fix the second universal ball to the second ball seat.

[0019] By adopting the above technical solution, the arrangement of the second ball seat, the second universal ball and the second locking member can facilitate the adjustment of the angle of the lower deviation-correcting wheel.

[0020] Optionally, the folding mechanism includes: a frame, wherein the first mounting frame is fixedly connected to the frame; A table top, the table top is fixedly connected to the frame, the material guide plate is higher than the upper surface of the table top, and the material guide plate is arranged to be inclined downward toward one side of the table top; and Two pressing assemblies; the two pressing assemblies are symmetrically arranged on the table about a preset virtual center line, and the pressing assemblies include: Vertical side bars, the vertical side bars are fixedly connected to the table top, and the width between the vertical side bars in the two pressing assemblies is adapted to the width of the raw material after folding; a connecting seat, the connecting seat being fixedly connected to the table top, the connecting seat being located both on a side of the vertical side bar close to the material guide plate and on a side of the vertical side bar away from a preset virtual center line; and A transverse pressure rod is horizontally arranged, and a first feeding gap is left between the transverse pressure rod and the upper surface of the table; one end of the transverse pressure rod is fixedly connected to the connecting seat, and the other end extends to one side of a preset virtual center line; along the feeding direction, the distance between the two transverse pressure rods gradually decreases.

[0021] By adopting the above technical solution, the guide plate is set higher than the table surface and tilted downward, which can guide the raw materials to be transported to the table surface after being peeled off from the coil; the two pressing components are symmetrically arranged, and the width between the vertical side rods is adapted to the width of the raw materials after folding, so that the raw materials can be folded on both sides after entering between the two vertical side rods; a first material passing gap is left between the horizontal pressing rod and the table surface, and the spacing gradually decreases, which helps to fold the raw materials into two layers and allow them to enter the next process.

[0022] Optionally, the folding mechanism further includes an adapter frame and two guide assemblies, the adapter frame being fixedly connected to the frame; the two guide assemblies being symmetrically arranged about a preset virtual center line; the guide assemblies including: a vertical rod, the vertical rod being fixedly connected to the adapter frame; and A cross bar is fixedly connected to one end of the vertical bar close to the table top, and the cross bar has a top supporting end, the top supporting end of the cross bar is close to the vertical side bar, and a second material passing gap is left between the top supporting end of the cross bar and the vertical side bar.

[0023] By adopting the above technical solution, the ends of the horizontal bars cooperate with the vertical side bars to guide the raw materials, so that the raw materials can be folded along the preset folding lines as much as possible.

[0024] Optionally, the top supporting end of the crossbar is a round head.

[0025] By adopting the above technical solution, the raw material can be confined between the top supporting end of the cross bar and the table surface, thereby reducing the wear of the raw material caused by the top supporting end of the cross bar.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The deviation measuring mechanism can detect whether the material is deflected. The processor controls the deviation correcting mechanism based on the detection results, automatically adjusting the material so that the actual folding line coincides with the preset folding line, reducing manual input and making operation more convenient. 2. The upper correcting wheel of the correcting mechanism can be adjusted between a correcting position and a withdrawing position.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 2-7 This application is described in further detail.

[0030] The embodiment of the present application discloses a material folding device with automatic deviation correction. Figure 2 The automatic deviation-correcting folding device includes a material guide plate 1 and a folding mechanism 2 arranged in sequence along the feeding direction, and also includes a deviation-correcting mechanism 4 arranged on the material guide plate 1 and a deviation-measuring mechanism 3 arranged on the folding mechanism 2.

[0031] Reference Figure 2 and Figure 3 The folding mechanism 2 includes a frame 21, a table 22, and two pressing assemblies 23; the table 22 is fixedly connected to the frame 21, the upper surface of the table 22 is horizontal, the upper surface of the guide plate 1 is higher than the upper surface of the table 22, and the upper surface of the guide plate 1 is inclined downward toward the side of the table 22, so that the raw material 01 is peeled off from the coil and is guided by the guide plate 1 to be transported to the table 22 in the folding mechanism 2; The two pressing assemblies 23 are symmetrically arranged on the table 22 about a preset virtual center line 011. The pressing assemblies 23 include vertical side bars 231, a connecting seat 232, and a horizontal pressing bar 233. The vertical side bars 231 are fixedly connected to the table 22. The width between the vertical side bars 231 in the two pressing assemblies 23 is adapted to the width of the raw material 01 after folding. That is, after the raw material 01 enters the table 22, under the guidance of the vertical side bars 231 on both sides, the two sides of the raw material 01 are folded to form a folded sheet 012, and the outer edge 0122 of the folded sheet 012 contacts the vertical side bars 231. The connecting seat 232 is fixedly connected to the table 22. The connecting seat 232 is located on both the side of the vertical side rod 231 close to the material guide plate 1 and the side of the vertical side rod 231 away from the preset virtual center line 011. The transverse pressure rod 233 is arranged horizontally, and a first material passing gap is left between the transverse pressure rod 233 and the upper surface of the table 22. The thickness of the first gap is approximately the thickness of two layers of raw materials 01. One end of the transverse pressure rod 233 is fixedly connected to the connecting seat 232, and the other end extends to the side of the preset virtual center line 011. Moreover, along the feeding direction, the distance between the two transverse pressure rods 233 gradually decreases, that is, the two transverse pressure rods 233 form a V-shaped structure, and the opening of the V is facing the side of the material guide plate 1. When the raw material 01 passes through the folding mechanism 2, under the joint guidance of the horizontal pressure rod 233 and the vertical side rod 231, the raw material 01 is folded into two layers and then passes through the first material feeding gap and enters the next process.

[0032] Reference Figure 3 and Figure 4 In order to further ensure that the raw material 01 is folded according to the preset folding line 013, in some embodiments of the present application, the folding mechanism 2 further includes an adapter frame 24 and two guide assemblies 25; the adapter frame 24 is directly or indirectly fixedly connected to the frame 21, and the guide assemblies 25 are arranged on the adapter frame 24, and the two guide assemblies 25 are symmetrically arranged about the preset virtual center line 011; The guide assembly 25 includes a vertical rod 251 and a horizontal rod 252. The vertical rod 251 is vertically arranged, and the top of the vertical rod 251 is fixedly connected to the adapter frame 24; the horizontal rod 252 is horizontally arranged, and the horizontal rod 252 is fixedly connected to the end of the vertical rod 251 close to the table 22, that is, the horizontal rod 252 is fixedly connected to the bottom end of the vertical rod 251; the gap left between the horizontal rod 252 and the upper surface of the table 22 can accommodate a single layer of raw materials 01 passing through; the horizontal rod 252 has a top supporting end, and the top supporting end of the horizontal rod 252 is close to the vertical side rod 231, and a second material passing gap is left between the top supporting end of the horizontal rod 252 and the vertical side rod 231, and the second material passing gap is used to accommodate a single layer of raw materials 01 passing through; During the operation, the raw material 01 is limited between the top supporting end of the cross bar 252 and the table 22. In order to reduce the wear of the top supporting end of the cross bar 252 on the raw material 01, the top supporting end of the cross bar 252 is set to a round head; because the end of the cross bar 252 cooperates with the vertical side bar 231 to guide the raw material 01, the raw material 01 can be folded along the preset folding line 013 as much as possible.

[0033] Reference Figure 4 and Figure 5 In order to further ensure that the raw material 01 is folded along the folding line 013, the deflection detection mechanism 3 is used to detect whether the raw material 01 is offset so as to subsequently adjust the position of the raw material 01; the deflection detection mechanism 3 includes a first mounting frame 31 and two detection components 32; the first mounting frame 31 is connected to the folding mechanism 2, specifically, the first mounting frame 31 is fixedly connected to the table 22 in the folding mechanism 2, and the adapter frame 24 for mounting the guide assembly 25 is fixedly connected to the first mounting frame 31, so that the adapter frame 24 is fixedly connected to the frame 21 and the table 22; After the raw material 01 is folded, two folded sheets 012 are formed. Each detection assembly 32 is used to detect the inner edge 0121 of the folded sheet 012. The detection assembly 32 includes a gooseneck tube 321, a detection seat 322, an infrared transmitter 323, an infrared receiver 324, and a processor 325. One end of the gooseneck tube 321 is fixedly connected to the first mounting frame 31, and the other end is fixedly connected to the detection seat 322. The detection seat 322 is provided on both sides of the preset virtual center line 011. The ends of the two transverse pressure rods 233 that are close to each other are suspended ends. The detection seat 322 is located on the side of the suspended end of the transverse pressure rod 233 close to the material guide plate 1. In this part, both sides of the raw material 01 are in a flipped-up state, but are not completely pressed into a folded state by the transverse pressure rod 233. A groove 3221 is formed on the side of the detection seat 322 away from the preset virtual center line 011. The groove 3221 is used to accommodate the inner edge 0121 of the folding sheet 012 when it is in the flipped-up state. The inner edge 0121 of the folding sheet 012 is inserted into the groove 3221 and can move forward as a whole with the raw material 01 in the groove 3221. The infrared transmitter 323 and the infrared receiver 324 are both fixedly connected to the detection base 322 and are both located in the groove 3221. On the upper and lower sides of the groove 3221, one side is provided with the infrared transmitter 323, and the other side is provided with the infrared receiver 324. The infrared receiver 324 is used to receive the light beam emitted by the infrared transmitter 323. Because the detection base 322 is connected to the gooseneck tube 321, the gooseneck tube 321 can be twisted to make the light beam emitted by the infrared transmitter 323 perpendicular to the folding piece 012 in the flipped state. When the material 01 does not deviate from the preset virtual center line 011, the subsequent actual fold line 013 coincides with the preset fold line 013. In this case, there is a 1mm gap between the light beam emitted by each infrared emitter 323 and the inner edge 0121 of the fold. If the material 01 is bent, the folded sheet 012 in the flipped state will prevent the infrared receiver 324 from receiving the light beam. The processor 325 is fixedly connected to the first mounting frame 31, and the processor 325 is communicatively connected to the infrared transmitter 323 and the infrared receiver 324, and the processor 325 is communicatively connected to the correction mechanism 4 to control the correction mechanism 4 to correct the deviation; it receives a signal indicating whether the infrared receiver 324 receives the light beam. If one of the infrared receivers 324 cannot receive the light beam, the processor 325 receives and processes the signal, and then transmits the signal to the correction mechanism 4 to control the correction mechanism 4 to correct the deviation.

[0034] Reference Figure 6 The correcting mechanism 4 is located at the material inlet end of the folding mechanism 2. Two correcting mechanisms 4 are provided, and the correcting mechanisms 4 are provided on the material guide plate 1. The correcting mechanism 4 includes an adjusting component 41 and a main correcting component 42. The adjusting assembly 41 includes a second mounting frame 411, a connecting rod 412 and a first motor 413. The second mounting frame 411 is fixedly connected to the guide plate 1; the connecting rod 412 is perpendicular to the second axis, and the connecting rod 412 is rotatably connected to the second mounting frame 411 around the second axis; the second axis is horizontally arranged, and the second axis is perpendicular to the preset virtual center line 011; the first motor 413 is connected between the connecting rod 412 and the second mounting frame 411 to drive the connecting rod 412 to rotate around the second axis. Specifically, the housing of the first motor 413 is fixedly connected to the second mounting frame 411, and one end of the connecting rod 412 is fixedly connected to the output shaft of the first motor 413; the first motor 413 is communicatively connected to the processor 325. After receiving the instruction of the processor 325, the first motor 413 drives the connecting rod 412 to rotate along the second mounting frame 411; The main deflection-correcting assembly 42 includes an upper wheel base 421, an upper deflection-correcting wheel 422, and a second motor 423. The upper wheel base 421 and the upper deflection-correcting wheel 422 are located above the guide plate 1. The upper wheel base 421 is connected to the end of the connecting rod 412 away from the first motor 413, and the upper deflection-correcting wheel 422 is connected to the upper wheel base 421. Driven by the first motor 413, the upper deflection-correcting wheel 422 can be adjusted between a deflection-correcting posture and a withdrawal posture. When the upper deflection-correcting wheel 422 is in the deflection-correcting posture, the upper deflection-correcting wheel 422 is used to press the raw material 01 onto the guide plate 1; During the process of adjusting the upper deflection-correcting wheel 422 from the deflection-correcting posture to the withdrawing posture, the distance between the upper deflection-correcting wheel 422 and the material guide plate 1 increases, and the upper deflection-correcting wheel 422 loosens the raw material 01; Regarding the connection method of the upper deflection correcting wheel 422 and the upper wheel seat 421, specifically: the upper deflection correcting wheel 422 is connected to the upper wheel seat 421 by rotating around a first axis, the first axis is parallel to the upper plate surface of the guide plate 1, and the angle formed between the first axis and the preset virtual center line 011 is greater than 0° and not equal to 90°; therefore, when the raw material 01 is pressed against the guide plate 1 by the upper deflection correcting wheel 422, as the upper deflection correcting wheel 422 rotates, the raw material 01 can be pushed to move on the guide plate 1; in the two deflection correcting mechanisms 4, the two upper deflection correcting wheels 422 are symmetrically arranged about the preset virtual center line 011, and the two deflection correcting wheels can move the raw material 01 in different directions; In order to facilitate the movement of the raw material 01, a flexible rubber ring 424 is coaxially fixed on the wheel surface of the upper correcting wheel 422. After the flexible rubber ring 424 contacts the raw material 01, it is easier to push the raw material 01 to move; The second motor 423 is connected between the upper wheel base 421 and the upper correcting wheel 422 to drive the upper correcting wheel 422 to rotate along the upper wheel base 421. Specifically, the housing of the second motor 423 is fixedly connected to the upper wheel base 421, and the output shaft of the second motor 423 is coaxially fixedly connected to the upper correcting wheel 422. In addition, the second motor 423 is also in communication with the processor 325. During the operation, if the first motor 413 and the second motor 423 receive instructions from the processor 325, the first motor 413 drives the connecting rod 412 to rotate, and the main correcting component 42 rotates synchronously with the connecting rod 412. The main correcting component 42 rotates to the upper correcting wheel 422 to press the raw material 01 to the guide plate 1, and the second motor 423 drives the main correcting wheel to rotate, so that the raw material 01 can be pushed forward while pushing the raw material 01 to the side to ensure that the center line of the raw material 01 is at the preset virtual center line 011, so as to ensure that the subsequent actual folding line 013 coincides with the preset folding line 013.

[0035] Reference Figure 7In some embodiments of the present application, the main correction component 42 further includes a first ball seat 425, a first universal ball 426 and a first locking piece 427; the first ball seat 425 is fixedly connected to the upper wheel seat 421; the first universal ball 426 is fixedly connected to the end of the connecting rod 412 away from the first motor 413, and the first universal ball 426 is universally hinged to the first ball seat 425. In the present disclosure, a ball groove adapted to the first universal ball 426 is provided on the first ball seat 425, and the first universal ball 426 can rotate freely in the ball groove; the first locking piece 427 is connected to the first ball seat 425 and the first universal ball The first universal ball 426 is fixed to the first ball seat 425 by the first locking piece 427.
