Description

Technical Field

[0001] This invention relates to the field of biscuit production, and in particular to a conveying device for biscuit production with a correction system. Background Technology

[0002] The biscuit production line is an automated food machinery equipment used for biscuit processing. It mainly consists of a forming machine, a tunnel-type hot air circulating electric oven, an oil sprayer, a turning machine, a biscuit sorting machine, a biscuit filling machine, a packaging table, a cooling line, and other equipment. The production line adopts CPU module control and back-mounted motor drive technology to realize the fully automated operation of the entire process from feeding, three-stage pressing, forming, baking, oil spraying, cooling to packaging.

[0003] The invention patent with announcement number CN109987392B discloses a conveyor belt alignment system and a conveyor belt mechanism for a biscuit production line. The system corrects the deviation of the conveyor belt by adjusting the swing of the alignment rollers, thereby reducing wear on the conveyor belt. In its embodiment, at least two sets of alignment rollers are used, and the conveyor belt passes around the alignment rollers in an S-shape, which can achieve a better alignment effect.

[0004] Utility model patent CN205328080U discloses a self-correcting conveyor device for biscuit production machinery. A photoelectric switch is installed on a support frame at the edge of the conveyor belt. The photoelectric switch is connected to a control mechanism, which in turn is connected to a cylinder. During operation, this device prevents conveyor belt deflection, significantly improving biscuit quality and extending the conveyor belt's lifespan. Furthermore, its automatic correction during production increases production efficiency.

[0005] Existing conveyor belt correction devices mainly rely on pairs of photoelectric detection devices for monitoring and adjustment correction devices. Once the photoelectric detection device detects a shift in the conveyor belt, the correction device performs correction work based on the monitoring results. However, most of the existing photoelectric positions are fixed, which are easily contaminated with dirt during food production, affecting the accuracy of the photoelectric detection device and frequently causing the correction device to be activated, thus affecting normal biscuit processing. Summary of the Invention

[0006] The core of this invention lies in the use of dual photoelectric detection units, which enables self-diagnosis during the detection process, providing strong anti-interference capabilities and solving the problem of existing photoelectric detection devices being easily affected by external factors. Simultaneously, the electromagnetic block-eccentric rotating shaft structure achieves fast response speed and precise resetting.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A conveying device for biscuit production with a web-correcting system includes a pair of matched frames. Multiple driving rollers and a driven roller are connected between the two frames. The driven roller is located on the same side of the driving rollers. A pair of web-correcting units, matching the position of the driven roller, are connected to the frames. Each web-correcting unit includes an eccentric rotating shaft sleeved on the driven roller and a stepper motor fixed to the side of the frame away from the driven roller. The power output end of the stepper motor passes through the frame and extends to the other side, where a web-correcting screw is fixedly connected. The web-correcting screw rotates... The moving connection is a lead screw nut. The outer side of the eccentric rotating shaft is fitted with a fixed frame. The fixed frame includes an outer frame. The inner wall of the outer frame is carved with an arc-shaped movable groove with an angle of 90 degrees. An electromagnetic block is fixedly connected to the lower side wall of the arc-shaped movable groove. The eccentric rotating shaft includes a rotating shaft body that matches the outer frame. The lower end of the rotating shaft body is fixedly connected with a limiting lug that matches the arc-shaped movable groove. The limiting lug attracts the energized electromagnetic block. The lower end of the fixed frame is fixedly connected with a connecting post. A ball joint is hinged between the lead screw nut and the connecting post.

[0009] Two frames are fixedly connected to photoelectric detection units at their close ends. Each photoelectric detection unit includes an electric slide rail fixedly connected to the frame. An anti-deviation detection unit is slidably connected inside the electric slide rail. The anti-deviation detection unit includes an electric slider slidably connected to the electric slide rail. An electric push rod is fixedly connected to the electric slider. A C-block is fixedly connected to the end of the electric push rod away from the electric slider. The open end of the C-block faces the conveyor belt. When the electric push rod is extended to its limit, the conveyor belt extends into the C-block. A photosensitive unit and a light-emitting unit are fixedly connected to the upper and lower inner walls of the C-block, respectively. Precise deviation correction is achieved through the deviation correction unit, and automatic re-inspection is performed by the anti-deviation detection unit.

[0010] Furthermore, both electric chute slabs are covered with protective frames on their outer sides. The protective frames are fixedly connected to the frame. An isolation curtain is fixedly connected to the opening on the side of the protective frame away from the frame. The isolation curtain consists of multiple elastic fibers that are intertwined and wrapped together, making it difficult for the light-emitting unit and the photosensitive unit to be contaminated by dirt in the environment.

[0011] Furthermore, before the correction unit starts working, the electric slider will randomly move to any position of the electric slide rail. Then the electric push rod will be activated to push out the C-shaped block, and then move to the end of the electric slide rail away from the driven roller, so that the isolation curtain can clean the light-emitting unit and the photosensitive unit.

[0012] Furthermore, if the photosensitive unit detects dirt twice in a row, it will contact maintenance workers for manual cleaning, reducing the frequency of manual intervention and increasing the smoothness of biscuit production.

[0013] Furthermore, a buffer pad is connected between the protective frame and the electric slide. The buffer pad includes an elastic pad filled with an oily buffer solution, in which multiple buffer balls are suspended to reduce the impact intensity caused by the biscuit falling from the conveyor belt onto the anti-deviation detection unit and the electric slide.

[0014] Furthermore, multiple weight-reducing cavities are carved into the driven roller to reduce its weight and make it easier to adjust its height.

[0015] Meanwhile, a rotating disk is used to replace the first light-emitting unit. The rotating disk is rotatably connected to the lower inner end of the C-shaped block, and multiple second light-emitting units are fixedly connected to the upper end of the rotating disk. A transparent plate is also fixedly connected to the upper end of the rotating disk. Before the detection begins, the rotating disk is rotated so that at least two light-emitting units on the rotating disk are covered by the transmission belt. The photosensitive unit has at least two incomplete light source illumination points, making the light source illumination area more concentrated and easier to detect area changes. At the same time, even if the second light-emitting unit is damaged, it will not affect the normal operation of the anti-bias detection unit.

[0016] Compared with the prior art, the advantages of this invention are:

[0017] This solution employs a belt alignment correction unit. When the conveyor belt deviates, the corresponding electromagnetic block is de-energized. A stepper motor drives the alignment screw, which in turn moves the screw nut. Power is transmitted through a ball joint, connecting column, and fixed frame, causing the limit lug of the eccentric shaft to slide upward along the arc-shaped movable groove, lifting the corresponding end of the driven roller for precise alignment correction. After alignment, the electromagnetic block is re-energized and repositioned. The stepper motor rotates in the opposite direction, restoring the driven roller to a horizontal state. An anti-deviation detection unit automatically re-checks the alignment, forming a closed-loop control system. The anti-deviation detection units on both sides of the frame move C-blocks via electric sliders and electric push rods. Using a light-emitting unit and a photosensitive unit to detect changes in the illuminated area, the direction of deviation can be accurately determined. When the detection results from both sides are inconsistent, the system can automatically identify stains on the C-block or the light-emitting unit, providing a self-diagnostic function. The photoelectric detection unit's working interval can be self-cleaned by random movement in conjunction with an isolation curtain, reducing manual maintenance. During normal operation, the electromagnetic block constantly attracts the limit lug, ensuring the stability of the driven roller's position.

[0018] By using a rotating disk to replace the first light-emitting unit, the illumination area of ​​the light source is more concentrated, making it easier to detect changes in area. At the same time, even if the second light-emitting unit is damaged, it will not affect the normal operation of the photoelectric detection unit. Attached Figure Description

[0031] The technical solutions will now be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention.

[0032] First implementation method:

[0033] Please see Figure 1-3 ,and Figure 6-8A conveying device for biscuit production with a correction system includes a pair of matched frames 1. Multiple driving rollers 2 and a driven roller 3 are connected between the two frames 1. The driving rollers 2 are powered by an electric motor connected to them (this is known technology and is therefore disclosed in detail). The driven roller 3 is located on the same side of the multiple driving rollers 2. A pair of correction units, matching the position of the driven roller 3, are connected to the frame 1. Each correction unit includes an eccentric rotating shaft 11 sleeved on the driven roller 3 and a stepper motor 5 fixed on the side of the frame 1 away from the driven roller 3. The power output end of the stepper motor 5 passes through the frame 1 and extends to the other side, where a correction screw 6 is fixedly connected. A screw nut 7 is rotatably connected to the correction screw 6. The screw nut 7 also contains steel balls and a reverser, enabling the correction screw 6 and screw nut 7 to perform normal correction. The function of the lead screw structure is as follows: the outer side of the eccentric rotating shaft 11 is fitted with a fixed frame 10, the fixed frame 10 includes an outer frame 1001, the inner wall of the outer frame 1001 is carved with an arc-shaped movable groove 1002, the angle of the arc-shaped movable groove 1002 is 90 degrees, an electromagnetic block 1003 is fixedly connected to the lower side wall of the arc-shaped movable groove 1002, the eccentric rotating shaft 11 includes a rotating shaft body 1101 that matches the outer frame 1001, the lower end of the rotating shaft body 1101 is fixedly connected with a limiting ear block 1102 that matches the arc-shaped movable groove 1002, the limiting ear block 1102 is attracted to the energized electromagnetic block 1003, wherein when the driven roller 3 is in a non-correction state, the connection position with the rotating shaft body 1101 is located on the lower side of the overall axis of the eccentric rotating shaft 11, the lower end of the fixed frame 10 is fixedly connected with a connecting column 9, and a ball joint 8 is hinged between the lead screw nut 7 and the connecting column 9.

[0034] Please see Figures 2-5 and Figure 9 Two frames 1 are respectively fixedly connected to photoelectric detection units at their close ends. Each photoelectric detection unit includes an electric slide 12 fixedly connected to the frame 1. An anti-deviation detection unit 13 is slidably connected inside the electric slide 12. The anti-deviation detection unit 13 includes an electric slider 1301 slidably connected to the electric slide 12. An electric push rod 1302 is fixedly connected to the electric slider 1301. A C-shaped block 1303 is fixedly connected to the end of the electric push rod 1302 away from the electric slider 1301. The open end of the C-shaped block 1303 faces the transmission belt 4. When the electric push rod 1302 is extended to its limit, the transmission belt 4 extends into the C-shaped block 1303. A photosensitive unit 1305 and a light-emitting unit 1304 are respectively fixedly connected to the upper and lower inner walls of the C-shaped block 1303.

[0035] In this embodiment, when the conveyor belt 4 is normally conveying biscuits, multiple active rollers 2 drive the belt to rotate, while the driven rollers 3 are driven to rotate by the friction of the conveyor belt 4. During the operation of the conveying device, every ten minutes, the two photoelectric detection units will be activated together: the electric push rod 1302 extends to its maximum length, and at the same time, the electric slider 1301 moves to the position furthest from the conveyor belt 4 within the electric slide chute 12. Then, the electric slider 1301 slowly drives the photoelectric detection unit toward the conveyor belt 4. The entire process takes no less than one minute. During the movement of the photoelectric detection unit, if the light-receiving area received by the two photosensitive units 1305 does not change, it indicates that the conveyor belt 4 is in normal conveying operation and no correction work is required. If the illuminated area received by photosensitive unit 1305 changes, it indicates that the transmission belt 4 has shifted towards the side with a smaller illuminated area. The correction unit on the side with a smaller illuminated area of ​​photosensitive unit 1305 needs to be activated. If the illuminated area detected by one photosensitive unit 1305 changes while the other does not, it indicates that there is dirt on the photoelectric detection unit on the side where the illuminated area did not change, which affects the normal detection work of C-block 1303 and light-emitting unit 1304. It needs to be cleaned during the working interval of the photoelectric detection unit. When the illuminated area received by the photosensitive unit 1305 with a changed illuminated area increases, the transmission belt 4 shifts to the opposite side, and the correction unit on the opposite side is activated. Conversely, it indicates that the transmission belt 4 shifts to itself, and the correction unit on the same side needs to be activated.

[0036] When the correction unit receives the start command, the electromagnetic block 1003 is de-energized, and the stepper motor 5 starts, driving the correction screw 6 to rotate. This allows the screw nut 7 to move along the correction screw 6 toward the driven roller 3. At this time, the screw nut 7 will have a tendency to synchronously drive the fixed frame 10 and the eccentric shaft 11 toward the driven roller 3. However, due to the presence of the ball joint 8, the fixed frame 10 and the eccentric shaft 11 will not move completely along the axial direction of the correction screw 6 in space. At the same time, the fixed frame 10 and the eccentric shaft 11 are separated by the arc-shaped movable groove 10. Constrained by 02 and the limiting ear block 1102, the limiting ear block 1102 will move upward along the arc-shaped movable groove 1002, causing the driven roller 3 and the started correction unit to move upward, thereby enabling the transmission belt 4 to perform correction work on the other side. 15 seconds after the correction unit is started, the electromagnetic block 1003 is energized, and the stepper motor 5 rotates in the reverse direction to the initial position, so that the driven roller 3 returns to the horizontal state. The photoelectric detection unit immediately performs a re-inspection. When it is found that the transmission belt 4 still has a deviation, the correction work continues until the correction is completed.

[0037] By setting up a correction unit, when the conveyor belt 4 deviates, the corresponding electromagnetic block 1003 is de-energized. The stepper motor 5 drives the correction screw 6 to move the screw nut 7. The power is transmitted through the ball joint 8, connecting column 9 and fixed frame 10, causing the limit ear block 1102 of the eccentric rotating shaft 11 to slide upward along the arc-shaped movable groove 1002, lifting the corresponding end of the driven roller 3 to achieve precise correction. After correction, the electromagnetic block 1003 is re-energized and repositioned. The stepper motor 5 rotates in the opposite direction to restore the driven roller 3 to a horizontal state, and the photoelectric detection unit automatically re-inspects, forming a closed-loop control. The photoelectric detection units on both sides of the frame 1 drive the C-block 1303 to move through the electric slider 1301 and electric push rod 1302. The light-emitting unit 1304 and the photosensitive unit 1305 detect changes in the illuminated area, which can accurately determine the direction of deviation. When the detection results on both sides are inconsistent, the system can automatically identify that there are stains on the C-block 1303 or the light-emitting unit 1304, which has a self-diagnostic function. The working gap of the photoelectric detection unit can be self-cleaned by randomly moving in conjunction with the isolation curtain 16, reducing manual maintenance. During normal operation, the electromagnetic block 1003 constantly attracts the limiting ear block 1102 to ensure the stable position of the driven roller 3.

[0038] Specifically, each time the stepper motor 5 works, the distance that the lead screw nut 7 moves along the axial direction of the correction lead screw 6 does not exceed 5mm, and the electromagnetic block 1003 remains in the normally open state when the driven roller 3 is working normally, so that the driven roller 3 is not easy to deviate.

[0039] Both electric slides 12 are covered with protective frames 14 on their outer sides. The protective frames 14 are fixedly connected to the frame 1. An isolation curtain 16 is fixedly connected to the opening on the side of the protective frame 14 away from the frame 1. The isolation curtain 16 includes multiple elastic fibers, which are intertwined and wrapped together. When the correction unit is not in working state, it will be pulled into the protective frame 14 by the electric push rod 1302, so that the light-emitting unit 1304 and the photosensitive unit 1305 are not easily contaminated by dirt in the environment.

[0040] Before the correction unit starts working, the electric slider 1301 will randomly move to any position of the electric slide rail 12. Then the electric push rod 1302 will start to push out the C-shaped block 1303, and then move to the end of the electric slide rail 12 away from the driven roller 3, so that the isolation curtain 16 can clean the light-emitting unit 1304 and the photosensitive unit 1305, and the cleaning position is not easily concentrated in the same position, which is not likely to affect the cleaning effect.

[0041] When the photosensitive unit 1305 detects dirt twice in a row, it contacts maintenance workers for manual cleaning, reducing the frequency of manual intervention and increasing the smoothness of biscuit production.

[0042] A buffer pad 15 is connected between the protective frame 14 and the electric slide 12. The buffer pad 15 includes an elastic pad 1501, which is filled with an oily buffer solution. The oily buffer solution is preferably silicone oil. Multiple buffer balls 1502 are suspended in the oily buffer solution to reduce the impact intensity of the biscuit falling from the conveyor belt 4 on the anti-deviation detection unit 13 and the electric slide 12, so that the working state of the electric slide 12 and the anti-deviation detection unit 13 is not easily affected.

[0043] Multiple weight-reducing cavities are carved into the driven roller 3 to reduce the weight of the driven roller 3 and reduce the difficulty of adjusting the height of the driven roller 3.

[0044] In addition, the control and power supply methods of the electrical units (including but not limited to stepper motor 5, electric slide 12 and anti-deviation detection unit 13, etc.) in this application are all well-known technologies to those skilled in the art. Those skilled in the art can make reasonable settings based on the existing technology to meet the usage requirements of this application. Among them, the electric push rod 1302 needs to move, and when wired power supply is used, auxiliary power supply can be provided by drag chain.

[0045] Second implementation method:

[0046] Please see Figure 10 A rotating disk 1306 is rotatably connected to the lower inner wall of the C-shaped block 1303. Multiple light-emitting units 2 are fixedly connected to the upper end of the rotating disk 1306. A transparent plate 1307 is fixedly connected to the upper end of the rotating disk 1306. The rotating disk 1306 replaces the light-emitting unit 1304. The detection process is the same as in the first embodiment. Before the detection starts, the rotating disk 1306 is rotated so that at least two light-emitting units on the rotating disk 1306 are covered by the transmission belt 4. The photosensitive unit 1305 has at least two incomplete light source illumination points. Compared with the first method, the light source illumination area in this embodiment is more concentrated, making it easier to detect area changes. At the same time, even if some of the light-emitting units 2 are damaged, it will not affect the normal operation of the anti-bias detection unit 13.

[0047] Compared to the first implementation method, the detection of the offset of the transmission belt 4 is more accurate in this implementation method. However, the use of the rotating disk 1306 will also increase the corresponding cost. Those skilled in the art need to make a reasonable choice based on actual usage requirements.

[0048] The above description is merely a preferred embodiment of the present invention; it encompasses all the protection scope of the present invention. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the present invention, based on the technical solutions and improved concepts of the present invention, should be covered within the protection scope of the present invention.
