Description

Technical Field

[0001] The invention relates to the technical field of production line cleaning, in particular to a transmission production line, and more particularly to a cake production transmission method based on automatic cleaning. Background Art

[0002] As a food that is deeply loved by consumers, the production process of pastries involves multiple links, including raw material preparation, mixing, molding, baking, cooling, packaging, etc. In order to improve production efficiency, ensure product quality and reduce production costs, pastry manufacturers generally use transmission production lines for automated production. In the process of transporting pastries on the production line, there will be pastry crumbs left on the conveyor belt of the production line. In order to ensure the cleanliness of the conveyor belt, it is usually necessary to use a cleaning device to clean the conveyor belt of the production line.

[0003] Chinese patent CN216511057U discloses a cleaning device for a food production line, which adjusts the height of a dust nozzle and a cleaning cotton block by rotating a driving handle in cooperation with a threaded sleeve to drive a threaded rod to move upward or downward according to the height of a conveying device of the production line, and sucks food residues on the conveying device into a dust collecting box through a negative pressure dust suction device in cooperation with a dust suction pipe and a dust suction nozzle, and then drives a forward screw and a reverse screw to reciprocate forward and reverse through a motor in cooperation with a rotating shaft, a half gear, a first gear and a second gear, and finally drives two cleaning cotton blocks to clean the top of the conveying device during the reciprocating forward and reverse rotation of the forward screw and the reverse screw.

[0004] Although the above patent uses a negative pressure vacuum device in conjunction with a vacuum tube and a vacuum nozzle to suck away the debris on the conveying device, the width of the conveyor belt included in the conveying device is relatively wide, and the cakes are arranged on the conveyor belt, so that there will be debris everywhere on the surface of the conveyor belt.

DETAILED DESCRIPTION

[0037] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] Reference Figures 1 to 13 As shown: a transmission production line, including a conveyor belt 1 for conveying cakes, and also including a gantry 2, a gathering mechanism 3 and a transfer mechanism 4; the gantry 2 includes two vertical plates 21 and a horizontal plate 22, the two vertical plates 21 are respectively arranged on both sides of the conveyor belt 1 in parallel, and the ends of the vertical plates 21 are provided with a connecting shaft 211 and a first spring 212, the connecting shaft 211 is connected to the vertical plates 21, the first spring 212 is sleeved on the connecting shaft 211, and the two ends of the horizontal plate 22 are respectively connected to the middle position of the top of the two vertical plates 21; the gathering mechanism 3 includes two The scraper 31, two limit plates 32, two position control mechanisms 33, two limit control mechanisms and a downward pressure control mechanism 35, the two scrapers 31 correspond to the two vertical plates 21 respectively, the scraper 31 is connected to the connecting shaft 211, the first spring 212 applies an upward force to the scraper 31, the two limit plates 32 correspond to the two scrapers 31 respectively, one end of the limit plate 32 is located between the other end of the scraper 31 and the vertical plate 21 corresponding to the scraper 31, so that the scraper 31 can extend between the two limit plates 32, and the scraper 31 and the limit plate 33 are connected to the vertical plate 21 corresponding to the scraper 31. The two position control mechanisms 33 are respectively arranged on the two vertical plates 21 through hinge connection. The position control mechanisms 33 include a first screw rod 331, a first moving block 332, a driving plate 333 and a first rotation driver 334. Both ends of the first screw rod 331 are connected to the vertical plates 21. The first moving block 332 is arranged on the first screw rod 331. Both ends of the driving plate 333 are axially connected to the first moving block 332 and the limiting plate 32 respectively. The first rotation driver 334 is arranged on one side of the first screw rod 331. Used to drive the first screw 331 to rotate, two limit control structures 34 are respectively arranged on the two limit plates 32, and the limit control structure 34 is used to keep the limit plates 32 translated so that the two limit plates 32 remain parallel; the transfer mechanism 4 includes a cover plate 41 and a lifting control mechanism 42, and an exhaust port 411 is opened at the upper end of the cover plate 41, and the exhaust port 411 is externally connected to a dust removal device, and both sides of the cover plate 41 are connected to the two limit plates 32, and the lifting control mechanism 42 is arranged on the horizontal plate 22, and the output end of the lifting control mechanism 42 is connected to the cover plate 41.

[0039] The gantry 2 can be installed at any position of the conveyor belt 1 according to the position of other equipment on the conveyor belt 1. If the gantry 2 is set at the end of the conveyor belt 1, when the cakes move on the conveyor belt 1 and need to be packaged at the end of the conveyor belt 1, the two position control mechanisms 33 respectively adjust the positions of the two limit plates 32, and the first rotary driver 334 drives the first screw 331 to rotate, and the first moving block 332 moves along the first screw 331. The first moving block 332 will drive the limit plate 32 to move to the edge of the conveyor belt 1 through the driving plate 333 to prevent the scraper 31 and the limit plate 32 from hindering the movement of the cakes. When the packaging step of producing cakes is set before reaching the gathering mechanism 3, the two position control mechanisms 33 drive the two limit plates 32 to move toward the middle of the conveyor belt 1, and the two limit control structures 34 are between the two limit plates. During the movement of 32, the two limit plates 32 are kept parallel to form a regular channel between the two limit plates 32. The scraper 31 rotates around the connecting shaft 211 under the action of the limit plates 32, so that the two scrapers 31 form a V-shaped opening facing the conveying direction of the conveyor belt 1. In the process of the two limit plates 32 moving toward the middle of the conveyor belt 1, the lifting control mechanism 42 drives the cover plate 41 to move downward, and the two sides of the cover plate 41 abut against the two limit plates 32 to form an independent space with an entrance. The external dust removal device extracts the gas in the independent space through the exhaust port 411 on the cover plate 41, and uses the airflow to extract the debris from the conveyor belt 1. Since the debris is gathered in a smaller space for processing, the dust removal device can discharge the debris more quickly, thereby concentrating the action points of the dust removal device and improving the debris processing efficiency.

[0040] Reference Figure 5 and Figure 6As shown: the limit control structure 34 includes a limit rod 341, a first guide structure 342 and two second guide structures 343; one end of the limit rod 341 vertically passes through the vertical plate 21 and is connected to the limit plate 32; the first guide structure 342 is arranged on the limit plate 32, and the first guide structure 342 includes a first sliding connecting rod 3421, the first sliding connecting rod 3421 is parallel to the conveyor belt 1, and the first sliding connecting rod 3421 is provided with a first sliding connecting block 3422 at both ends, one end of the limit rod 341 is slidably connected to the first sliding connecting rod 3421, and the limit rod 341 is perpendicular to the first sliding connecting rod 3421; the two second guide structures 34 3 are respectively arranged at both ends of the first guide structure 342, the guiding direction of the second guide structure 343 is perpendicular to the conveyor belt 1, the two second guide structures 343 connect the first guide structure 342 with the limiting plate 32, the second guide structure 343 includes a first guide slide bar 3431 and a second spring 3432, both ends of the first guide slide bar 3431 are connected to the limiting plate 32, the first sliding connection block 3422 is slidably arranged on the first guide slide bar 3431, the second spring 3432 is sleeved on the first guide slide bar 3431, and both ends of the second spring 3432 are respectively abutted against the first sliding connection block 3422 and the end of the first guide slide bar 3431.

[0041] When the position control mechanism 33 adjusts the position of the limit plate 32, the limit plate 32 needs to move between the middle and the edge of the conveyor belt 1. At the same time, the limit plate 32 is moved along the conveying direction of the conveyor belt 1 by the action of the scraper 31, and the limit plate 32 will also follow the scraper 31 to move toward the upper conveying surface of the conveyor belt 1. By setting the limit rod 341, the first guide structure 342 and the second guide structure 343, when the position control mechanism 33 adjusts the position of the limit plate 32, the limit plate 32 drives the limit rod 341 to slide relatively along the vertical plate 21. At this time, the limit rod 341 moves along its axial direction. , realizing the precise translation of the limit plate 32 between the middle and edge of the conveyor belt 1, one end of the limit rod 341 slides on the first sliding connecting rod 3421, maintaining the vertical relationship between the limit rod 341 and the limit plate 32, ensuring that the limit plate 32 always moves in the correct direction, and when the scraper 31 drives the limit plate 32 to move toward the upper conveying surface of the conveyor belt 1, the limit plate 32 realizes a smooth displacement through the relative sliding between the first guide slide bar 3431 and the first sliding connecting block 3422, so that the limit rod 341 is always perpendicular to the limit plate 32, ensuring the accuracy of the limiting effect.

[0042] Reference Figure 5 and Figure 7As shown: the gathering mechanism 3 also includes a downward pressure control mechanism 35, which is arranged on the horizontal plate 22. The downward pressure control mechanism 35 includes a downward pressure plate 351, two driving arms 352 and a driving structure 353; the downward pressure plate 351 is arranged parallel to the lower side of the horizontal plate 22; the two driving arms 352 are symmetrically arranged at the upper end of the downward pressure plate 351; the driving structure 353 is arranged at the upper end of the horizontal plate 22, and the driving structure 353 includes a double-headed screw 3531 and two second moving blocks 3532, and the two ends of the double-headed screw 3531 are Connected to the cross plate 22, the two second movable blocks 3532 are respectively arranged on the two threaded parts of the double-headed screw 3531, and the two second movable blocks 3532 respectively correspond to the two driving arms 352, and the two ends of the second driving arm 352 are respectively axially connected to the lower pressure plate 351 and the second movable block 3532. The driving structure 353 also includes a second rotation driver 3533, and the second rotation driver 3533 is arranged at one end of the double-headed screw 3531. The second rotation driver 3533 is used to drive the double-headed screw 3531 to rotate.

[0043] Some debris will stick to the conveyor belt 1. If the interaction force between the lower end of the scraper 31 and the conveyor belt 1 is small, it is difficult for the scraper 31 to hinder the debris on the conveyor belt 1. By setting the downward pressure control mechanism 35, after the position control mechanism 33 adjusts the position of the scraper 31 and the limit plate 32, the downward pressure control mechanism 35 works, and the second rotation driver 3533 drives the double-headed screw 3531 to rotate slowly. As the double-headed screw 3531 rotates, the two second moving blocks 3532 move away from each other due to the action of the thread, and then the lower pressure plate 351 is driven to move steadily downward through the two driving arms 352. During the translation of the lower pressure plate 351, the bottom of the lower pressure plate 351 contacts the tops of the two scrapers 31 at the same time, applying a downward force to the two scrapers 31, which makes the scraper 31 fit more closely on the conveyor belt 1, thereby increasing the interaction force between the scraper 31 and the conveyor belt 1, so that the scraper 31 can more effectively remove the debris on the conveyor belt 1.

[0044] Reference Figure 4 and Figure 8 As shown: the gathering mechanism 3 also includes a first cleaning mechanism 36 and a quick disassembly structure 37; the first cleaning mechanism 36 is arranged at the lower part of the scraper 31 facing the conveying direction of the conveyor belt 1, the first cleaning mechanism 36 includes a mounting plate 361 and a plurality of first cleaning rollers 362, the mounting plate 361 is arranged on one side of the scraper 31, and the mounting plate 361 is connected to the scraper 31, and the plurality of first cleaning rollers 362 are arranged at equal intervals between the mounting plate 361 and the scraper 31, the first cleaning mechanism 36 also includes a third rotation driver 363 and a chain transmission structure 364, the third rotation driver 363 is arranged on the mounting plate 361; the quick disassembly structure 37 is arranged on the other side of the scraper 31.

[0045] When the debris is obstructed by the scraper 31, the debris will stick to the scraper 31, causing the debris to accumulate on the side of the scraper 31 facing the conveying direction of the conveyor belt 1. By providing a first cleaning mechanism 36 and a quick disassembly structure 37, the quick disassembly structure 37 can quickly install the first cleaning mechanism 36 on the scraper 31. During the operation of the scraper 31, the third rotary driver 363 continues to operate, and drives a plurality of first cleaning rollers 362 to rotate through the chain transmission structure 364. The first cleaning rollers 362 apply a force toward the middle of the conveyor belt 1 to the debris in front of the scraper 31, pushing the debris toward the channel between the two limit plates 32, thereby achieving efficient cleaning of the debris in front of the scraper 31 and effectively avoiding the accumulation of debris on the scraper 31.

[0046] Reference Figure 8 and Fig. 9 As shown: the quick disassembly and assembly structure 37 includes a plug-in positioning block 371, a clamping block 372 and a locking structure 373; the plug-in positioning block 371 is connected to the first cleaning mechanism 36, and a plug hole that matches the plug-in positioning block 371 is provided on the scraper 31; the clamping block 372 is connected to the plug-in positioning block 371; the locking structure 373 is arranged on the scraper 31, and the locking structure 373 includes a U-shaped frame 3731, two guide telescopic rods 3732, two clamping blocks 3733 and two third springs 3734, the U-shaped frame 3731 is connected to the scraper 31, two guiding telescopic rods 3732 are respectively arranged at the two ends of the U-shaped frame 3731, the guiding telescopic rod 3732 is slidably connected to the U-shaped frame 3731, two clamping blocks 3733 respectively correspond to the two guiding telescopic rods 3732, one side surface of the clamping block 3733 abuts against the scraper 31, two third springs 3734 are respectively mounted on the two guiding telescopic rods 3732, and the two ends of the third spring 3734 abut against the end of the U-shaped frame 3731 and the clamping block 3733 respectively.

[0047] After the first cleaning roller 362 has been used for a period of time, debris will adhere to the first cleaning roller 362 and contaminate the first cleaning roller 362. Therefore, the first cleaning roller 362 needs to be cleaned frequently. When the first cleaning mechanism 36 needs to be disassembled, the staff only needs to apply a force to the mounting plate 361 to move away from the scraper 31. The mounting plate 361 will drive the clamping block 372 to move by plugging in the positioning block 371. The movement of the clamping block 372 will push the two clamping blocks 3733 away from each other and compress the two third springs 3734. When the clamping block 372 is completely separated from the clamping block 3733, the two third springs 3734 respectively push the two clamping blocks 3733 to quickly reset for the next installation. Be prepared. When the first cleaning roller 362 is cleaned, the staff only needs to insert the plug-in positioning block 371 into the socket on the scraper 31 again. The plug-in positioning block 371 will drive the clamping block 372 to move toward the locking structure 373. The clamping block 372 will first push the two clamping blocks 3733 away from each other, and then under the action of the two third springs 3734, the clamping block 3733 will quickly reset and be clamped between the clamping block 372 and the scraper 31 to achieve a stable locking. Finally, use bolts to fix the clamping block 372 to the U-shaped frame 3731 to ensure that the first cleaning mechanism 36 is firmly installed on the scraper 31, thereby simplifying the installation and disassembly of the first cleaning mechanism 36 and improving the disassembly efficiency.

[0048] Reference Figure 3 and Fig.10 As shown: the lifting control mechanism 42 includes a second screw rod 421, a bevel gear transmission group 422, a third moving block 423 and two third guide structures 424; the second screw rod 421 is vertically arranged at the upper end of the middle part of the double-headed screw rod 3531; the bevel gear transmission group 422 is respectively arranged between the second screw rod 421 and the double-headed screw rod 3531; the third moving block 423 is arranged on the thread of the second screw rod 421, and the third moving block 423 is connected to the cover plate 41; the two third guide structures 424 are respectively arranged on both sides of the second screw rod 421, and the third guide structure 424 includes a mounting bracket 4241 and a guide telescopic column 4242, one end of the mounting bracket 4241 is connected to the cross plate 22, and the two ends of the guide telescopic column 4242 are respectively connected to the other end of the mounting bracket 4241 and the cover plate 41.

[0049] When the downward pressure control mechanism 35 applies a force toward the conveyor belt 1 to the scraper 31, the double-headed screw 3531 will rotate, and the rotation of the double-headed screw 3531 will be accurately transmitted to the second screw 421 through the bevel gear transmission group 422, so that the second screw 421 also starts to rotate. As the second screw 421 rotates, the third moving block 423 starts to descend, and at the same time, the third moving block 423 drives the cover plate 41 to move downward together, and the cover plate 41 also drives the extension of the guide telescopic column 4242 during the movement. The guide telescopic column 4242 correspondingly limits the rotation of the cover plate 41 to ensure that the cover plate 41 can move smoothly toward the two limit plates 32, thereby realizing the linkage between the downward pressure control mechanism 35 and the lifting control mechanism 42.

[0050] Reference Figure 7 and Fig.11 As shown, the driving arm 352 includes a telescopic arm 3521 and a telescopic spring 3522 ; the two ends of the telescopic arm 3521 are axially connected to the lower pressing plate 351 and the second moving block 3532 respectively; the telescopic spring 3522 is sleeved on the telescopic arm 3521 .

[0051] When the second screw 421 starts to drive the third moving block 423 to descend, the second screw 421 needs to rotate a sufficient number of times to enable the cover plate 41 to smoothly descend to a position closely abutting against the limit plate 32 through the third moving block 423. During this process, the rotational power of the second screw 421 comes from the driving of the double-headed screw 3531, so the double-headed screw 3531 also needs to rotate a sufficient number of times, which will cause the two second moving blocks 3532 to still move away from each other after the lower pressure plate 351 descends to the fixed position. Therefore, the driving arm 352 is set to a telescopic arm 3521 and a telescopic spring 3522. When the lower pressure plate 351 cannot continue to move downward due to resistance, the second moving block 3532 continues to move along the double-headed screw 3531, the telescopic arm 3521 begins to contract, and the telescopic spring 3522 is also gradually compressed, which together absorbs and buffers the downward force generated during the movement of the second moving block 3532, thereby preventing the lower pressure plate 351 from continuing to push the scraper 31 to move toward the conveyor belt 1.

[0052] Reference Figure 3 , Fig.10 and Fig.12 As shown: the transfer mechanism 4 also includes a second cleaning mechanism 43, which is arranged inside the cover plate 41. The second cleaning mechanism 43 includes a second cleaning roller 431, which is arranged inside the cover plate 41, and the direction of the axis of the second cleaning roller 431 is the same as the conveying direction of the conveyor belt 1. The second cleaning mechanism 43 also includes a fourth rotation driver 432, which is arranged outside the cover plate 41, and the fourth rotation driver 432 is used to drive the second cleaning roller 431 to rotate.

[0053] On the conveyor belt 1, the debris is guided by the scraper 31 and enters the narrow channel formed by the two limit plates 32 in an orderly manner. Since the debris is attached to the conveyor belt 1, even if the external dust removal device works at full capacity and tries to extract the air in the independent space to take away the debris, it is difficult to effectively remove the debris. At this time, the second cleaning mechanism 43 comes into play. When the cover plate 41 abuts against the two limit plates 32, the fourth rotary driver 432 drives the second cleaning roller 431 to rotate at high speed. The high-speed rotating second cleaning roller 431 lifts the debris on the conveyor belt 1 into the air. At this time, the flowing air extracted by the dust removal device can easily carry the lifted debris together, thereby removing the debris tightly attached to the conveyor belt 1.

[0054] Reference Fig.12 and Fig.13 As shown: the second cleaning mechanism 43 also includes a fourth guide structure 433 and a swing structure 434; the fourth guide structure 433 is arranged outside the cover plate 41, and the fourth guide structure 433 includes a second guide slide bar 4331 and a fourth moving block 4332, both ends of the second guide slide bar 4331 are connected to the cover plate 41, the second guide slide bar 4331 is parallel to the conveyor belt 1, and both ends of the second guide slide bar 4331 are arranged above the second cleaning roller 431, the fourth moving block 4332 is slidably arranged on the second guide slide bar 4331, and the fourth moving block 4332 is connected to the second cleaning roller 431; the swing structure 434 is arranged at the upper end of the cover plate 41, and the swing structure 434 is arranged at the upper end of the cover plate 41. The dynamic structure 434 is used to drive the fourth moving block 4332 to reciprocate along the second guide slide rod 4331. The swing structure 434 includes a swing arm 4341, a second sliding connecting rod 4342, a second sliding connecting block 4343 and a swing driver 4344. One end of the swing arm 4341 is axially connected to the fourth moving block 4332. A bar groove is provided on the swing arm 4341. The second sliding connecting rod 4342 is arranged in the bar groove. The second sliding connecting block 4343 is slidably arranged on the second sliding connecting rod 4342. The swing driver 4344 is arranged on the cover plate 41. The output end of the swing driver 4344 is connected to the second sliding connecting block 4343.

[0055] The channel between the two limit plates 32 has a certain width, so multiple second cleaning rollers 431 are required to work together to fully cover it. However, the existence of multiple second cleaning rollers 431 may hinder the debris from being effectively lifted into the air. At this time, the fourth guide structure 433 and the swing structure 434 come into play. The swing driver 4344 drives the second sliding connection block 4343 to swing back and forth within a preset angle. The swinging of the second sliding connection block 4343 not only drives the swing arm 4341 to swing through the second sliding connection rod 4342, but also enables the fourth moving block 4332 to reciprocate along the second guide slide rod 4331 through the transmission of the swing arm 4341, and finally makes the second cleaning roller 431 reciprocate between the two limit plates 32, thereby realizing that the second cleaning roller 431 completely covers the channel between the two limit plates 32, ensuring comprehensive cleaning of debris in the channel and significantly improving the cleaning efficiency.

[0056] A cake production and transmission method based on automatic cleaning comprises the following steps:

[0057] S1, the two position control mechanisms 33 adjust the distance between the two limit plates 32 so that the two limit plates 32 are close to each other, and the two limit plates 32 respectively drive the two scrapers 31 to move, and the two scrapers 31 form a V-shaped opening facing the conveying direction of the conveyor belt 1;

[0058] S2, the scraper 31 blocks the debris on the surface of the conveyor belt 1, and the debris moves along the scraper 31 toward between the two limit plates 32, so that the debris gathers within the coverage of the cover plate 41;

[0059] S3, the upgrade control mechanism controls the cover plate 41 to cover the upper ends of the two scrapers 31, the cover plate 41 and the two tube plates enclose an independent space, and the external dust removal device extracts the gas in the space, generates suction in the hole, and extracts the debris in the space.
