[0022] S2: By setting an electric double-headed telescopic device at the center of the inner wall of the linkage pipe, the electric double-headed telescopic device is used to control the limiting direction of the conical push block, thereby controlling the rotation direction of the linkage pipe and the bevel gear arranged at one end thereof, so as to control the position switching of the wire brushes on the two transmission lead screws.

[0023] S3: By setting an auxiliary gear rod at one end of the fixed frame far from the second elastic telescopic rod, when the transmission lead screw drives the auxiliary gear rod to pass through the rack arranged in the limit sliding box, the auxiliary gear rod drives the fixed frame to rotate in reverse, so as to facilitate cleaning the wire brush by using the ultrasonic cleaning tank.

[0024] Due to the adoption of the above technical solutions, the technical progress achieved by the present invention compared with the prior art is:

[0025] 1. The present invention provides an automatic conveying device for biscuit manufacturing and its use method. By starting the steam ejector arranged at the top of the inner wall of the cleaning bin, the biscuit crumbs in the gaps of the conveyor belt are cleaned, and the sauce attached to the gaps of the conveyor belt is softened by the steam. The first arc-shaped fixing block arranged at one end of the foam brush is pushed by the push rod, so that the foam brush moves reciprocally horizontally in the limit frame, and the cleaning liquid in the liquid storage bin is sent into the foam brush to brush the sauce attached to the top of the conveyor belt. When the conveyor belt is finished being brushed, the dry ice ejector arranged at one end of the top of the inner wall of the cleaning bin far from the steam ejector is started, and dry ice particles are sprayed onto the surface of the conveyor belt. By using a strong cold impact, the residual foam and water stains on the surface of the conveyor belt are cleaned, and by using the characteristic of dry ice sublimation, the water vapor residue in the cleaning bin is reduced, further solving the problem that in the use process of the traditional automatic conveying device for biscuit manufacturing, when transporting walnut shortbread biscuits, the biscuit crumbs and sauce are easily attached to the conveying gaps, which is likely to affect the food safety of walnut shortbread biscuits over time.

[0026] 2. The present invention provides an automated conveying device for biscuit manufacturing and its usage method. By arranging a first elastic telescopic rod at the center of one side of the inner wall of the limiting frame, and connecting its output end to the side of the foam brush away from the first arc-shaped fixing block, the foam brush is enabled to move horizontally and repeatedly within the limiting frame, so that the cleaning liquid flows out along the holes in the foam brush to brush the top of the conveyor belt, thereby generating foam to achieve the purpose of cleaning and brushing the top of the conveyor belt. This not only enables more meticulous cleaning of the gaps in the conveyor belt, but also the horizontal force generates less friction compared to the friction generated by the traditional reverse-rotating brush cleaning, reducing the damage to the conveying main body. Moreover, during the process of the foam brush brushing the conveyor belt, the small-amplitude and high-frequency vibration generated is conducive to throwing out the water stains attached to the surface of the conveyor belt, further solving the problem that in the process of using the traditional automated conveying device for biscuit manufacturing, the conveyor belt is often cleaned by a reverse-rotating brush, which not only easily damages the conveyor belt, but also cannot brush the stains remaining in the gaps of the conveyor belt more meticulously.

[0027] 3. The present invention provides an automated conveying device for biscuit manufacturing and its usage method. By arranging a conical push block at the output end of the electric double-headed telescopic device, the protruding end is used to push the conical push block to limit the elastic limit blocks arranged at the upper and lower ends of the inner cavity of the linkage pipe. When the linkage bevel gear drives the bevel gear ring to rotate, the protrusions arranged on the inner wall of the bevel gear ring are used to contact the elastic limit blocks. Since one end of the elastic limit block is limited by the conical push block and cannot be retracted, the corresponding end of the bevel gear ring drives the linkage pipe to rotate, enabling the linkage gear rod to control the position switching of the two wire brushes on the transmission screw rod according to the rotation direction of the bevel gear, further solving the problem that in the process of using the traditional automated conveying device for biscuit manufacturing, when cleaning the bottom of the conveyor belt, dirt easily adheres to the surface of the wire brush, and in order to avoid secondary pollution to the conveyor belt, it is often necessary to stop the machine to replace and clean the wire brush.

Detailed implementation manners

[0040] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0041] Such as Figures 1 to 11As shown in the figure, an automatic conveying device for biscuit manufacturing according to an embodiment of the present invention includes a conveying main body 1. One end of the outer wall of the conveying main body 1 is drivingly connected to a first pulley 2. One end of the first pulley 2 is drivingly connected to a linkage bevel gear 3. And one end of the outer wall of the linkage bevel gear 3 is fixedly connected to a cleaning bin 4. One end of the top inner wall of the cleaning bin 4 is fixedly connected to a steam ejector 5. One end of the top inner wall of the cleaning bin 4 away from the steam ejector 5 is fixedly connected to a dry ice ejector 6. The center of the bottom inner wall of the cleaning bin 4 is fixedly connected to an ultrasonic cleaning tank 7. The top of the cleaning bin 4 is fixedly connected to a slope plate 8. One end of the top outer wall of the cleaning bin 4 is fixedly connected to a liquid storage bin 9. A cleaning mechanism is arranged at the bottom of one side of the outer wall of the liquid storage bin 9. Both sides of the outer wall of the linkage bevel gear 3 are engaged with bevel gear rings 10. And one side of the outer wall of the bevel gear ring 10 is fixedly connected to one end of the top inner wall of the cleaning bin 4 close to the dry ice ejector 6. The inner wall of the bevel gear ring 10 is rotatably connected to a linkage pipe 11. And one end of the linkage pipe 11 is rotatably connected to the top of one side of the inner wall of the cleaning bin 4. An adjusting mechanism is arranged inside the linkage pipe 11. The end of the linkage pipe 11 away from the cleaning bin 4 is fixedly connected to a bevel gear 12. The bottom of one side of the outer wall of the bevel gear 12 is engaged with a driving bevel gear rod 13. And the top of the driving bevel gear rod 13 is rotatably connected to one end of the top inner wall of the cleaning bin 4 close to the bevel gear ring 10. The bottom of the driving bevel gear rod 13 is fixedly connected to a linkage gear rod 14. A lifting mechanism is arranged at the bottom of one side of the outer wall of the linkage gear rod 14.

[0042] During operation, by starting the conveying main body 1, the walnut shortbread cookies are conveyed by the conveying main body 1. Since the walnut shortbread cookies are likely to drop residues during transportation due to factors such as rich taste during the production process, through the slope plate 8 provided at the top of the cleaning bin 4, the crumbs dropped from the surface of the walnut shortbread cookies are guided along the slope plate 8 and accumulated on both sides of the conveying main body 1, facilitating subsequent cleaning. Since the walnut shortbread cookies are made to have various flavors during the production process, sandwich sauces are filled inside the cookies. During transportation, the sauces in the cookies are not completely solidified, resulting in some sauces flowing out along the gaps between the cookies, thus carrying some cookie residues and adhering to the gaps of the conveyor belt (here the conveyor belts are all mesh belt conveyor belts). By starting the steam ejector 5 provided at the top of the inner wall of the cleaning bin 4, the cookie crumbs in the gaps of the conveyor belt are cleaned, and the sauces adhering to the gaps of the conveyor belt are softened by the steam. By providing a first pulley 2 at one end of the outer wall of the conveying main body 1 (the pulleys mentioned in the text are all composed of belts and pulleys), the first pulley 2 is used to drive a linkage bevel gear 3 provided on one side of the inner wall of the cleaning bin 4, which drives the bevel gear rings 10 provided on both sides of the outer wall, and the linkage pipe 11 provided on its inner wall rotates. By providing a bevel gear 12 at one end of the outer wall of the linkage pipe 11, the bevel gear 12 is used to drive a transmission bevel gear rod 13 to rotate, and the transmission bevel gear rod 13 drives a linkage gear rod 14 provided at its bottom to rotate. By providing gear shafts 31 on both sides at the top of the outer wall of the linkage gear rod 14, the gear shafts 31 drive a push rod 33 provided at their tops to rotate, and push a first arc-shaped fixing block 19 provided at one end of the foam brush 16, so that the foam brush 16 moves reciprocally horizontally in the limit frame 17, and the cleaning liquid in the liquid storage bin 9 is sent into the foam brush 16 to brush the sauces adhering to the top of the conveyor belt. At the same time, a push block 32 provided at the bottom of the gear shaft 31 is used to push a second arc-shaped fixing block 30 provided at one end of the outer wall of the wire brush 29, so that the wire brush 29 moves reciprocally horizontally in the fixing frame 27 to brush the sauces and residues adhering to the bottom of the conveyor belt. Since both the foam brush 16 and the wire brush 29 brush the conveyor belt in a horizontal movement manner, not only can the gaps in the conveyor belt be cleaned more carefully, but also the horizontal force is smaller than the friction generated by the traditional reverse-rotating brush cleaning, reducing the damage to the conveying main body 1. Moreover, during the process of the foam brush 16 and the wire brush 29 brushing the conveyor belt, the small-amplitude and high-frequency vibration generated is conducive to throwing out the water stains adhering to the surface of the conveyor belt. Since the wire brush 29 is at the bottom of the conveyor belt, during the long-term brushing process, some cookie residues are likely to adhere to the wire brush 29. By providing an ultrasonic cleaning pool 7 at the center of the bottom of the inner wall of the cleaning bin 4, and using the linkage gear rod 14 to control the lifting of the wire brush 29, it is completely immersed in the ultrasonic cleaning pool 7 for cleaning. When the conveyor belt is finished being brushed, start the dry ice ejector 6 provided at one end of the top of the inner wall of the cleaning bin 4 away from the steam ejector 5, and spray dry ice particles onto the surface of the conveyor belt.Using a strong cold impact to clean the foam and water stains remaining on the surface of the conveyor belt, and taking advantage of the sublimation property of dry ice to reduce the water vapor residue in the cleaning chamber 4, further solving the problem that in the process of using the traditional automated conveying device for biscuit manufacturing, when transporting walnut shortbread cookies, cookie crumbs and sauces are likely to adhere to the conveying gaps, which is likely to affect the food safety of walnut shortbread cookies over time.

[0043] The cleaning mechanism includes a telescopic hose 15 fixedly connected to the bottom of one side of the outer wall of the liquid storage chamber 9. One end of the telescopic hose 15 is fixedly connected with a foam brush 16. The two sides of the outer wall of the foam brush 16 are slidably connected with a limit frame 17, and one end of the outer wall of the limit frame 17 is fixedly connected to the top of one side of the inner wall of the cleaning chamber 4. The center of one side of the inner wall of the limit frame 17 is fixedly connected with a first elastic telescopic rod 18. The output end of the first elastic telescopic rod 18 is fixedly connected to one side of the outer wall of the foam brush 16. A first arc-shaped fixing block 19 is fixedly connected to the side of the foam brush 16 away from the first elastic telescopic rod 18.

[0044] During operation, by arranging the telescopic hose 15 at the bottom of one side of the outer wall of the liquid storage chamber 9, the cleaning liquid is sent into the foam brush 16 through the telescopic hose 15. When the gear shaft 31 drives the push rod 33 to push the first arc-shaped fixing block 19 arranged at one end of the outer wall of the foam brush 16, causing the foam brush 16 to move horizontally within the limit frame 17, by arranging the first elastic telescopic rod 18 at the center of one side of the inner wall of the limit frame 17, and connecting its output end to the side of the foam brush 16 away from the first arc-shaped fixing block 19, the foam brush 16 moves horizontally back and forth within the limit frame 17, enabling the cleaning liquid to flow out along the holes in the foam brush 16 to brush the top of the conveyor belt, thereby generating foam to achieve the purpose of cleaning and brushing the top of the conveyor belt. This not only can clean the gaps in the conveyor belt more meticulously, but also the horizontal force generates less friction compared to the friction generated by the traditional reverse-rotating brush cleaning, reducing the damage to the conveying main body 1. Moreover, during the process of the foam brush 16 brushing the conveyor belt, the small-amplitude and high-frequency vibration generated is conducive to throwing off the water stains attached to the surface of the conveyor belt, further solving the problem that in the process of using the traditional automated conveying device for biscuit manufacturing, the conveyor belt is often cleaned by a reverse-rotating brush, which not only easily damages the conveyor belt but also cannot brush the stains remaining in the gaps of the conveyor belt more meticulously.

[0045] The adjusting mechanism includes an electric double-headed telescopic device 20 fixedly connected to the center of the inner wall of the linkage pipe 11. The output ends of the electric double-headed telescopic device 20 are fixedly connected with conical push blocks 21. The two ends of the outer wall of the conical push blocks 21 are both lapped with elastic limit blocks 22, and the outer walls of the elastic limit blocks 22 are fixedly connected to the inner cavity of the linkage pipe 11. The top of the elastic limit block 22 is lapped with a protruding block 23, and one end of the outer wall of the protruding block 23 is fixedly connected to the inner wall of the conical gear ring 10.

[0046] During operation, an electric double-headed retractor 20 is arranged at the center of the inner wall of the linkage tube 11, one end of the electric double-headed retractor 20 is started, and the other end is recovered, and a conical push block 21 is arranged at the output end of the electric double-headed retractor 20, so that the extended end pushes the conical push block 21, and the elastic limit blocks 22 arranged at the upper and lower ends of the inner cavity of the linkage tube 11 are limited. When the linkage bevel gear 3 drives the bevel gear ring 10 to rotate, the protrusion 23 arranged on the inner wall of the bevel gear ring 10 is used to contact the elastic limit block 22. Since the elastic limit block 22 at one end is limited by the conical push block 21 and cannot be recovered, the bevel gear ring 10 at the corresponding end drives the linkage tube 11 to rotate, and the other end is arranged When the elastic limit block 22 loses the limit of the conical push block 21, so that the protrusion 23 in the conical gear ring 10 pushes the elastic limit block 22, the elastic limit block 22 is retracted into the linkage tube 11, so that the corresponding conical gear ring 10 is idle, thereby controlling the rotation direction of the conical gear 12, so that the linkage gear rod 14 can control the position switching of the two wire brushes 29 on the transmission screw 25 according to the rotation direction of the conical gear 12, further solving the problem that during the use of the traditional automatic conveying device for biscuit manufacturing, when cleaning the bottom of the conveyor belt, dirt is easily attached to the surface of the wire brush 29. In order to avoid secondary pollution to the conveyor belt, it is often necessary to stop the machine to replace and clean the wire brush 29.

[0047] The lifting mechanism includes a second pulley 24 that is transmission-connected to the bottom of one side of the outer wall of the linkage gear rod 14, one end of the second pulley 24 is transmission-connected to a plurality of transmission screws 25, and the threads of the transmission screws 25 are opposite, the outer wall of the transmission screw 25 is threadedly connected to a moving block 26, and the outer wall of the moving block 26 is slidably connected to the inner wall of the cleaning bin 4, the inner wall of the moving block 26 is rotationally connected to a fixed frame 27, one end of the inner wall of the fixed frame 27 is fixedly connected to a second elastic telescopic rod 28, and the output end of the second elastic telescopic rod 28 is fixedly connected to a wire brush 29, and the outer wall of the wire brush 29 is fixedly connected to the inner wall of the cleaning bin 4. The two sides of the wall are slidably connected to the inner wall of the fixed frame 27, and the end of the wire brush 29 away from the second elastic telescopic rod 28 is fixedly connected to the second arc-shaped fixed block 30, and the two sides of the top of the outer wall of the linkage gear rod 14 are meshed with gear shafts 31, and one side of the outer wall of the gear shaft 31 is fixedly connected to the inner wall of the cleaning chamber 4, and the bottom of the gear shaft 31 is fixedly connected to a push block 32, and one side of the outer wall of the push block 32 overlaps with one side of the outer wall of the second arc-shaped fixed block 30, and the top of the gear shaft 31 is fixedly connected to a push rod 33, and one side of the outer wall of the push rod 33 overlaps with one side of the outer wall of the first arc-shaped fixed block 19.

[0048] During operation, by arranging a second pulley 24 at the bottom on one side of the outer wall of the linkage gear rod 14, several transmission lead screws 25 arranged at one end are driven by the second pulley 24. Since the threads between the transmission lead screws 25 are opposite, when the transmission lead screws 25 rotate, the moving blocks 26 arranged on their outer walls will move in opposite directions. By arranging a fixed frame 27 on the inner wall of the moving block 26 and arranging a second elastic telescopic rod 28 at one end of the inner wall of the fixed frame 27, and arranging a wire brush 29 at the output end of the second elastic telescopic rod 28. When both sides at the top of the outer wall of the linkage gear rod 14 drive the gear shaft 31 to rotate, by arranging a push block 32 at the bottom of the gear shaft 31, when the push block 32 pushes the wire brush 29 away from the second arc-shaped fixing block 30 arranged at one end of the second elastic telescopic rod 28, the second elastic telescopic rod 28 is used to reset the wire brush 29, so as to achieve the lateral reciprocating movement of the wire brush 29 in the fixed frame 27 to brush the bottom of the conveyor belt. When there is more dirt attached to the surface of the wire brush 29, the linkage gear rod 14 is reversely rotated by the linkage pipe 11, so that the wire brushes 29 on the two transmission lead screws 25 in the cleaning bin 4 are replaced in position, further solving the problem that in the process of using the traditional automatic conveying device for biscuit manufacturing, when cleaning the conveyor belt, in order to avoid dirt attachment to the conveyor belt, it is often necessary to frequently stop the machine and clean and replace the wire brush 29, resulting in low biscuit conveying efficiency.

[0049] One end of the outer wall of the fixed frame 27 away from the second elastic telescopic rod 28 is fixedly connected with an auxiliary gear rod 34, and one end of the outer wall of the auxiliary gear rod 34 is slidably connected with the inner wall of the cleaning bin 4. One end of the inner wall of the cleaning bin 4 close to the transmission lead screw 25 is fixedly connected with a limit sliding box 35. A rack 36 is fixedly connected to the middle of the inner wall of the limit sliding box 35. One side of the outer wall of the rack 36 is meshed with one side of the outer wall of the auxiliary gear rod 34. A fitting block 37 is slidably connected to one end of the inner cavity of the moving block 26 close to the fixed frame 27. One end of the outer wall of the fitting block 37 is clamped with a groove opened on one side of the outer wall of the auxiliary gear rod 34. One side of the outer wall of the fitting block 37 is fixedly connected with a fixed column 38. A limit block 39 is slidably connected to the outer wall of the fixed column 38. One end of the outer wall of the limit block 39 is fixedly connected with the top of one side of the inner wall of the cleaning bin 4.

[0050] During operation, by setting an auxiliary gear rod 34 at one end of the fixing frame 27 away from the second elastic telescopic rod 28, when the wire brushes 29 on the two transmission lead screws 25 in the cleaning bin 4 are replaced in position, when the moving block 26 drives the fixing frame 27 to move downward, by setting a fitting block 37 at one end of the inner cavity of the moving block 26 close to the fixing frame 27, a fixing column 38 provided on one side of the outer wall of the fitting block 37 slides along the chute provided by the limiting block 39 provided on the top of one side of the inner wall of the cleaning bin 4, and the fitting block 37 extends out of the moving block 26, so that the auxiliary gear rod 34 is released from the limit of the fitting block 37. By setting a limiting sliding box 35 at one end of the inner wall of the cleaning bin 4 close to the transmission lead screw 25 and setting a rack 36 in the middle of the inner wall of the limiting sliding box 35, when the moving block 26 drives the auxiliary gear rod 34 to contact the rack 36 during the downward movement, the auxiliary gear rod 34 drives the fixing frame 27 to reverse until the brushing surface of the wire brush 29 faces downward, facilitating subsequent cleaning of the stains attached to the surface of the wire brush 29 by the ultrasonic cleaning tank 7. At the same time, the other transmission lead screw 25 drives the moving block 26 to move upward, so that the corresponding auxiliary gear rod 34 passes through the rack 36, thereby reversing the corresponding wire brush 29. When the moving block 26 moves to the top, the fixing column 38 slides into the chute provided by the limiting block 39 and pulls the fitting block 37 into the moving block 26 to fix the auxiliary gear rod 34, thus avoiding the problem that the wire brush 29 is prone to looseness during horizontal repeated brushing, resulting in damage to the equipment.

[0051] An automated conveying method for biscuit manufacturing, which uses the above-mentioned automated conveying device for biscuit manufacturing, and the method is as follows:

[0052] S1: Pass the conveying main body 1 through the cleaning bin 4, use the steam ejector 5 provided in the cleaning bin 4 to soften the sauce attached to the conveyor belt, then use the foam brush 16 and the wire brush 29 in cooperation with the cleaning liquid to deeply clean the conveyor belt, and finally use the dry ice ejector 6 to clean the foam and water stains attached to the conveyor belt;

[0053] S2: By setting an electric double-headed telescopic device 20 at the center of the inner wall of the linkage pipe 11, use the electric double-headed telescopic device 20 to control the limiting direction of the conical push block 21, thereby controlling the rotation direction of the linkage pipe 11 and the conical gear 12 provided at one end thereof, so as to control the position switching of the wire brushes 29 on the two transmission lead screws 25;

[0054] S3: By setting an auxiliary gear rod 34 at one end of the fixing frame 27 away from the second elastic telescopic rod 28, when the transmission lead screw 25 drives the auxiliary gear rod 34 to pass through the rack 36 provided in the limiting sliding box 35, the auxiliary gear rod 34 drives the fixing frame 27 to reverse, thus facilitating the cleaning of the wire brush 29 by the ultrasonic cleaning tank 7.

[0055] Specifically describe the working principle of the automatic conveying device for biscuit manufacturing and its usage method below.

[0056] As Figures 1 - 11As shown, by starting the conveying main body 1, the walnut shortbread cookies are conveyed by the conveying main body 1. During the production process of the walnut shortbread cookies, due to factors such as rich taste, it is easy to drop residues during transportation. Through the slope plate 8 arranged at the top of the cleaning bin 4, the debris falling from the surface of the walnut shortbread cookies is along the slope plate 8 and accumulates on both sides of the conveying main body 1, facilitating subsequent cleaning. During the production process of the walnut shortbread cookies, in order to make the flavors diverse, sandwich sauces are filled inside the cookies. During transportation, the sauces in the cookies are not completely solidified, resulting in some sauces flowing out along the gaps between the cookies, thus entraining some cookie residues and adhering to the gaps of the conveyor belt (here the conveyor belts are all mesh belt conveyor belts). By starting the steam ejector 5 arranged at the top of the inner wall of the cleaning bin 4, the cookie debris in the gaps of the conveyor belt is cleaned, and the sauces adhering to the gaps of the conveyor belt are softened by the steam. By arranging a first pulley 2 at one end of the outer wall of the conveying main body 1 (the pulleys mentioned in the text are all composed of belts and pulleys), the first pulley 2 drives a linkage bevel gear 3 arranged on one side of the inner wall of the cleaning bin 4, causing it to drive the bevel gear rings 10 arranged on both sides of the outer wall and making the linkage pipe 11 arranged on its inner wall rotate. By arranging a bevel gear 12 at one end of the outer wall of the linkage pipe 11, the bevel gear 12 drives a transmission bevel gear rod 13 to rotate, and the transmission bevel gear rod 13 drives a linkage gear rod 14 arranged at its bottom to rotate. By arranging gear shafts 31 on both sides at the top of the outer wall of the linkage gear rod 14, the gear shafts 31 drive a push rod 33 arranged at their tops to rotate, and push a first arc-shaped fixing block 19 arranged at one end of the foam brush 16, causing the foam brush 16 to reciprocate horizontally in the limit frame 17 and sending the cleaning liquid in the liquid storage bin 9 into the foam brush 16 to brush the sauces adhering to the top of the conveyor belt. At the same time, using a push block 32 arranged at the bottom of the gear shaft 31, pushing a second arc-shaped fixing block 30 arranged at one end of the outer wall of the wire brush 29, causing the wire brush 29 to reciprocate horizontally in the fixing frame 27 to brush the sauces and residues adhering to the bottom of the conveyor belt. Since both the foam brush 16 and the wire brush 29 brush the conveyor belt in a horizontal movement manner, not only can the gaps in the conveyor belt be cleaned more carefully, but also the horizontal force is smaller than the friction generated by the traditional reverse-rotation roller brush cleaning, reducing the damage to the conveying main body 1. Moreover, during the process of the foam brush 16 and the wire brush 29 brushing the conveyor belt, the small-amplitude and high-frequency vibration generated is conducive to throwing out the water stains adhering to the surface of the conveyor belt. Since the wire brush 29 is at the bottom of the conveyor belt, during the long-term brushing process, some cookie residues are easily attached to the wire brush 29. By arranging an ultrasonic cleaning pool 7 at the center of the bottom of the inner wall of the cleaning bin 4 and using the linkage gear rod 14 to control the lifting of the wire brush 29, making it completely immersed in the ultrasonic cleaning pool 7 for cleaning. By arranging an auxiliary gear rod 34 at the end of the fixing frame 27 far from the second elastic telescopic rod 28,When the wire brushes 29 on the two drive lead screws 25 in the cleaning bin 4 are replaced in position, when the moving block 26 drives the fixed frame 27 to move downward, by arranging a fitting block 37 at one end of the inner cavity of the moving block 26 close to the fixed frame 27, a fixed column 38 arranged on one side of the outer wall of the fitting block 37 slides along the chute arranged by the limiting block 39 at the top of one side of the inner wall of the cleaning bin 4, and the fitting block 37 extends out of the moving block 26, so that the auxiliary gear rod 34 is disengaged from the limit of the fitting block 37. By arranging a limiting sliding box 35 at one end of the inner wall of the cleaning bin 4 close to the drive lead screw 25 and arranging a rack 36 in the middle of the inner wall of the limiting sliding box 35, during the downward movement, the moving block 26 drives the auxiliary gear rod 34 to contact the rack 36, and the auxiliary gear rod 34 drives the fixed frame 27 to reverse until the brushing surface of the wire brush 29 faces downward, which is convenient for subsequent cleaning of the stains attached to the surface of the wire brush 29 by the ultrasonic cleaning tank 7. At the same time, the other drive lead screw 25 drives the moving block 26 to move upward, so that the corresponding auxiliary gear rod 34 passes through the rack 36, thereby reversing the corresponding wire brush 29. When the moving block 26 moves to the top, the fixed column 38 slides into the chute arranged by the limiting block 39 and pulls the fitting block 37 into the moving block 26 to fix the auxiliary gear rod 34, thus avoiding the problem that the wire brush 29 is prone to looseness during horizontal repeated brushing, which may cause damage to the equipment. When the conveyor belt finishes brushing, start the dry ice ejector 6 arranged at one end of the top of the inner wall of the cleaning bin 4 far from the steam ejector 5, spray dry ice particles onto the surface of the conveyor belt, and use the strong cold impact to clean the residual foam and water stains on the surface of the conveyor belt. And by using the characteristic of dry ice sublimation, reduce the water vapor residue in the cleaning bin 4, further solving the problem that in the process of using the traditional automatic conveying device for biscuit manufacturing, when transporting walnut shortbread biscuits, biscuit crumbs and sauces are easily attached to the conveying gaps, which is likely to affect the food safety of walnut shortbread biscuits over time.

Therefore, the modifications or improvements without departing from the spirit of the present invention are all within the protection scope of the present invention.
