Description

Technical Field

[0001] This invention relates to the field of pastry conveying technology, and in particular to a pastry processing conveying mechanism. Background Technology

[0002] As a traditional food, the industrialization of pastry production is crucial for achieving large-scale, standardized, and safe and stable supply. Traditional pastry processing has long relied on manual or single-machine operations, resulting in bottlenecks such as low production efficiency, difficulty in hygiene control, and poor product consistency, making it difficult to meet the large-scale demands of the modern market. Therefore, deeply integrating continuous, automated processing and conveying mechanisms with pastry production has become a core path for the transformation of the food industry. To this end, patent CN217295918U discloses a conveying mechanism for pastry processing, which includes a conveying body and a conveying tray. The conveying body includes a body shell, a transmission structure, a fixed rotating structure, a controller, a power supply, a driven wheel support structure, and a drive wheel support structure. The transmission structure includes a conveyor belt, a driven wheel, a drive wheel, and a drive motor. The fixed rotating structure includes a rotating control head, a telescopic rod, a second support plate, an electromagnet plate, and a sensor. The conveying tray is placed on the conveyor belt and includes a first support plate, a resin board layer, a sensor transmitter, and a stainless steel layer. The beneficial effects of this utility model are: its structure is reasonable, its degree of automation is high, and it can automatically adjust the height and angle of the pastry according to the set program, making the work of processing personnel more convenient and comfortable, greatly improving the processing efficiency, and having good applicability. The above-mentioned conveying mechanism for pastry processing can automatically adjust the height and angle of pastries according to the set program, making it more convenient and comfortable for processing personnel. However, once the production line is built, it cannot realize the free combination of products with different subsequent processes, such as different filling injection machines, different sauce injection machines, etc. When it is necessary to change the existing product process, such as sending pastry dough from one production line to the filling injection machine of another production line, it does not have the ability to respond quickly to the market, the production line is too rigid, and the products are monotonous. Summary of the Invention

[0003] The purpose of this invention is to provide a pastry processing conveying mechanism to solve the problem of rigid production lines in existing pastry processing conveying mechanisms.

The two sets of front reversing gear sets mesh with the lower plate single transmission gear and the upper plate single transmission gear, respectively. A front misalignment shaft is fixed on one side of the front reversing gear set, and the front misalignment shaft is meshed with the upper plate connecting gear.

[0008] Preferably, a forward misaligned tooth is provided on one side of the forward misaligned shaft, and the forward misaligned tooth is meshed with the lower single drive gear. A forward reset tooth set is provided on one side of the forward misaligned tooth, and two sets of forward reset tooth sets are provided. The two sets of forward reset tooth sets mesh with the lower single drive gear and the upper single drive gear, respectively.

[0009] Preferably, the driving wheel at the top of the front reset gear set is provided with a rear change gear set in an alternating manner, and there are two sets of rear change gear sets. The two sets of rear change gear sets mesh with the lower plate transmission gear set and the upper plate transmission gear set, respectively. A rear misalignment shaft is fixed on one side of the rear change gear set.

[0010] Preferably, a rear misaligned tooth is provided on one side of the rear misaligned shaft, and the rear misaligned tooth is meshed with the upper disk transmission gear set. A rear reset tooth set is provided on one side of the rear misaligned tooth, and two sets of rear reset tooth sets are provided. The two sets of rear reset tooth sets are respectively meshed with the lower disk transmission gear set and the upper disk transmission gear set.

[0011] Preferably, the merging mechanism includes a left merging disc installed at the end of the left conveyor, and a right merging disc installed at the end of the right conveyor on the side of the left merging disc. The edges of both the left and right merging discs are provided with concave grooves.

[0012] Preferably, a second gear is installed at the bottom of both the left and right material mixing trays, and a first gear is connected to one side of the second gear, while a third gear meshes with one side of the first gear.

[0013] Preferably, the limiting structure includes an upper connecting gear set installed on the top of the left and right conveyor channels, and a lower connecting gear set installed at the bottom of the upper connecting gear set. The upper connecting gear set is meshed with the first tooth, and the lower connecting gear set is meshed with the second tooth. Both ends of one side of the upper connecting gear set are provided with pinions, and the top of each pinion is provided with a limiting rod. Elastic plates are provided at the corners of the limiting rods.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the pastry processing conveying mechanism, through a purely mechanical lane changing and merging mechanism, effectively breaks the deadlock of the traditional pastry production line, and realizes automatic cross lane changing and orderly merging of double-line pastries with a highly reliable and low-cost mechanical structure, which significantly improves the process reorganization capability and market response speed of the production line. 1. By incorporating a track-changing mechanism, pastries can be automatically and precisely switched from the left conveyor to the right conveyor, or vice versa, without altering the physical layout of the production line or requiring manual intervention. This effectively addresses the core defect that "once the production line is built, the process route is completely fixed." When market demand changes and different pastries need to be combined with processing steps on another line, this mechanism can achieve rapid switching, giving the production line a high degree of process reconfiguration capability. This allows a single production line to flexibly cope with the production needs of multiple varieties and customization, significantly enhancing market responsiveness. Furthermore, the concave grooves of the upper and lower clamping plates are used to "flexibly fix" the pastries and rotate them synchronously. Before and after the track change, the feeding and releasing of the pastries are precisely controlled by the limiting structure, which avoids sliding friction between the pastries and the equipment, effectively preventing the surface of the pastries from being scratched or damaged during the track change process, and ensuring the appearance quality of the products. Furthermore, the track-changing action is triggered by the complete rotation of the drive wheel. By adjusting the speed of the drive motor, the frequency of track-changing can be precisely controlled, thereby flexibly adjusting the production interval between pastries and making it easier to accurately match the rhythm of the preceding and following processes. Furthermore, the entire lane-changing and merging action is achieved by a purely mechanical transmission system consisting of a worm gear, a turbine, a drive wheel, and a series of gear sets. Compared with electric or pneumatic lane-changing systems that rely on sensors, cylinders, and programmable controllers, mechanical transmission has the characteristics of definite action and high reliability. It is particularly suitable for the humid and dusty environment that may exist in food processing workshops. It has good stability, low failure rate, and ensures continuous production. 2. By setting up a merging mechanism, the left and right merging trays rotate continuously and synchronously in opposite directions, feeding pastries from two independent conveyor channels into a single conveyor channel in a precise, orderly and alternating manner, like gears meshing. This achieves dynamic and seamless merging, avoiding the risks of waiting, congestion or collision caused by intermittent operation, ensuring a continuous and smooth merging process. This allows downstream packaging machines, testing machines or decorating machines and other single-line equipment to obtain a continuous and stable material flow, eliminating equipment start-ups or idling caused by uneven material supply, thereby improving the utilization rate of downstream single-line equipment. Furthermore, by adjusting the speed of the drive servo motor, the rotation speed of the mixing tray can be precisely controlled, thereby flexibly setting the spacing of the combined pastries on a single conveyor, providing ideal conditions for subsequent automatic packaging. Moreover, the pastries from the left and right production lines form a fixed alternating arrangement after being combined. This predictable order provides a natural sorting basis for packaging by specific variety combinations, such as mixed flavor gift boxes, without the need for additional complex sorting systems.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-15This invention provides a pastry processing conveying mechanism, comprising a left conveyor 1 and a right conveyor 5 installed on one side thereof; a switching mechanism 2 is provided at the middle position of the left conveyor 1 and the right conveyor 5, and a limiting structure 6 is installed at one end of the switching mechanism 2; a single-sided conveyor 3 is installed at one end of the left conveyor 1 and the right conveyor 5, and a merging mechanism 4 is provided at one end of the single-sided conveyor 3; the switching mechanism 2 includes a lower clamping plate 22 installed at the middle position of the left conveyor 1 and the right conveyor 5, and an upper clamping plate 21 penetrates through the top of the lower clamping plate 22; a driving wheel 23 is provided at the bottom of the lower clamping plate 22; an upper plate transmission gear set 25 is installed at the bottom of one side of the driving wheel 23; a lower plate transmission gear set 24 is installed at the top of the upper plate transmission gear set 25; an upper plate single transmission gear 29 is installed at the bottom of the other side of the driving wheel 23, and a lower plate single transmission gear 28 is installed at the top of the upper plate single transmission gear 29; the driving wheel 23 is designed with... A worm gear 26 is provided, and a worm 27 is installed on one side of the worm gear 26. An upper plate connecting gear 212 is installed at the bottom of the upper chuck 21, and the upper plate connecting gear 212 meshes with the upper plate transmission gear set 25 and the upper plate single transmission gear 29 respectively. A lower plate connecting gear 222 is installed at the bottom of the lower chuck 22, and the lower plate connecting gear 222 meshes with the lower plate transmission gear set 24 and the lower plate single transmission gear 28 respectively. The outer edge of the driving wheel 23 is provided with front-changing teeth. Group 231, and the front reversing gear group 231 is provided with two groups. The two groups of the front reversing gear group 231 mesh with the lower plate single transmission gear 28 and the upper plate single transmission gear 29 respectively. A front misaligned shaft 232 is fixed on one side of the front reversing gear group 231, and the front misaligned shaft 232 is meshed with the upper plate connecting gear 212. A front misaligned tooth 233 is provided on one side of the front misaligned shaft 232, and the front misaligned tooth 233 is meshed with the lower plate single transmission gear 28. Reference Figures 1-11As shown, when the device is in use, two types of pastries are conveyed on the left conveyor 1 and the right conveyor 5. Two different fillings are injected during the conveying process. When the fillings of the two types of pastries need to be replaced in response to market demand, a servo motor is installed on one side of the worm gear 27. The servo motor is started to drive the worm gear 27 and the worm wheel 26 that meshes with it to rotate. The worm wheel 26 is fixed to the drive wheel 23, causing the drive wheel 23 to rotate counterclockwise. At this time, the pastries conveyed on the left conveyor 1 have been conveyed into the concave groove of the lower clamping plate 22, and the concave groove of the upper clamping plate 21 is in the open state in the initial mode to ensure the passage of the pastries. The drive wheel 23 rotates counterclockwise, and the two sets of front changing gear teeth 231 approach the lower plate single drive gear 28 and the upper plate single drive gear 29. The front end of the lower front changing gear teeth 231 has more teeth than the upper front changing gear teeth 231, and it meshes with the upper plate single drive gear 29 first. The upper plate single drive gear 29 meshes with the upper plate connecting gear 212, so that the upper plate The connecting gear 212 and the upper clamping plate 21 fixed thereto rotate counterclockwise first. The extra teeth correspond to the rotation of the upper clamping plate 21, so that its concave groove matches the concave groove of the lower clamping plate 22, which has a flexible fixing effect on the pastry. After the two sets of front-changing gear teeth 231 mesh with the lower plate single drive gear 28 and the upper plate single drive gear 29 at the same time, the lower plate connecting gear 222 and the upper plate connecting gear 212 cause the upper clamping plate 21 and the lower clamping plate 22 to drive the pastry to rotate counterclockwise by 1 rpm. At 80° above the right conveyor 5, under the continuous rotation of the drive wheel 23, the forward misalignment shaft 232 engages with the upper plate connecting gear 212, and the forward misalignment teeth 233 engage with the lower plate connecting gear 222 through the lower plate single transmission gear 28. The two engage simultaneously, respectively driving the upper clamping plate 21 to rotate clockwise and the lower clamping plate 22 to rotate counterclockwise. With the pastry as the center point, the pastry loses its limit and leaves under the conveying of the right conveyor 5, completing the transfer of the pastry from the left conveyor 1 to the right conveyor 5. A front reset tooth set 234 is provided on one side of the front misaligned tooth 233, and two sets of the front reset tooth set 234 are provided. The two sets of the front reset tooth set 234 mesh with the lower plate single drive gear 28 and the upper plate single drive gear 29, respectively. A rear change-track tooth set 235 is provided alternately on the edge of the driving wheel 23 at the top of the front reset tooth set 234, and two sets of the rear change-track tooth set 235 are provided. The two sets of the rear change-track tooth set 235 mesh with the lower plate drive gear set 24 and the upper plate drive gear set 29, respectively. The gear set 25 meshes with each other. A rear offset shaft 236 is fixed on one side of the rear shift gear set 235. A rear offset tooth 237 is provided on one side of the rear offset shaft 236, and the rear offset tooth 237 meshes with the upper drive gear set 25. A rear reset tooth set 238 is provided on one side of the rear offset tooth 237, and there are two sets of rear reset tooth sets 238. The two sets of rear reset tooth sets 238 mesh with the lower drive gear set 24 and the upper drive gear set 25 respectively. Reference Figures 8-11As shown, when the pastry changes lanes from the left conveyor 1 to the right conveyor 5, the drive wheel 23 continues to rotate. The two sets of front reset gear sets 234 mesh with the lower plate single drive gear 28 and the upper plate single drive gear 29. Through the lower plate connecting gear 222 and the upper plate connecting gear 212, the lower clamping plate 22 and the upper clamping plate 21 rotate counterclockwise simultaneously until the concave groove is above the right conveyor 5. At this point, the lower clamping plate 22 is in an unfolded state, facilitating the transport of pastries from the right conveyor 5 to the concave groove of the upper clamping plate 21. The drive wheel 23 continues to rotate, and the two sets of rear lane-changing gear sets 235 mesh with the lower plate drive gear set 24 and the upper plate drive gear set 25 respectively. At this time, the upper... The rear shift gear set 235 has a large number of teeth at its front end, and both the lower plate drive gear set 24 and the upper plate drive gear set 25 are two-gear combinations. Therefore, the upper rear shift gear set 235 first meshes with the lower plate drive gear set 24, and drives the lower clamping plate 22 to rotate clockwise through the lower plate connecting gear 222, corresponding to the concave groove of the upper clamping plate 21. Then, it continues to rotate, rotating the pastry onto the left conveyor 1. At this time, the rear misalignment shaft 236 meshes with the inner lower plate drive gear set 24. The bottom of the inner lower plate drive gear set 24 is lower than that of the outer lower plate drive gear set 24, so that the rear misalignment shaft 236 can contact the inner lower plate drive gear set 24, but not the outer rear misalignment shaft 236. 36. The bottom of the toothed plate passes through a non-contact mechanism. The rear misaligned tooth 237 meshes with the upper plate drive gear set 25. The two mesh simultaneously, causing the upper clamping plate 21 and the lower clamping plate 22 to rotate clockwise and counterclockwise, respectively. The concave groove unfolds, and the pastry is conveyed away by the left conveyor 1. The drive wheel 23 continues to rotate. The two sets of rear reset tooth sets 238 mesh with the lower plate drive gear set 24 and the upper plate drive gear set 25, causing the concave grooves of the upper clamping plate 21 and the lower clamping plate 22 to rotate to the initial position above the left conveyor 1. Because the front change tooth set 231, the front misaligned tooth 233, and the front reset tooth set 234 are all height-aligned with the lower plate single drive gear 28 and the upper plate single drive gear 29. Then, the reversing gear set 235, the rear misaligned gear set 237, and the rear reset gear set 238 are all aligned with the lower plate transmission gear set 24 and the upper plate transmission gear set 25. The positions of the lower plate single transmission gear 28, the upper plate single transmission gear 29, the lower plate transmission gear set 24, and the upper plate transmission gear set 25 are all staggered and spaced apart. Therefore, when the drive wheel 23 rotates, the non-meshing teeth and gears will not come into contact. Thus, when the drive wheel 23 rotates one revolution, it can complete one reversal from the left conveyor 1 to the right conveyor 5 and from the right conveyor 5 to the left conveyor 1. The speed can be adjusted according to the processing needs to meet the interval time between pastries. The outer edge of the upper clamping plate 21 is provided with a first tooth 211, and the outer edge of the lower clamping plate 22 is provided with a second tooth 221. The limiting structure 6 includes an upper connecting gear set 62 installed on the top of the left conveyor 1 and the right conveyor 5, and a lower connecting gear set 65 is installed at the bottom of the upper connecting gear set 62. The upper connecting gear set 62 is meshed with the first tooth 211, and the lower connecting gear set 65 is meshed with the second tooth 221. Both ends of one side of the upper connecting gear set 62 are provided with pinions 64, and the top of each pinion 64 is provided with a limiting rod 61. Each corner of the limiting rod 61 is provided with an elastic piece 63. Reference Figure 4 , Figure 5 and Figure 12 As shown, when the upper clamping plate 21 and the lower clamping plate 22 rotate, when the concave grooves of the lower clamping plate 22 and the upper clamping plate 21 rotate clockwise to above the left conveyor channel 1, the upper clamping plate 21 rotates to the unfolded state. During the rotation, the first tooth 211 on its outer edge meshes with the connecting gear set 62. The connecting gear set 62 meshes with the small gear 64 near the left conveyor channel 1, causing the limiting rod 61 connected to it to rotate counterclockwise, opening the channel. This allows the pastry to be embedded in the concave groove of the lower clamping plate 22 under the conveying of the left conveyor channel 1. When the upper clamping plate 21 rotates counterclockwise and closes the concave groove, the first tooth 211 drives the limiting rod 61 to reverse and reset through the connecting gear set 62, thus intercepting the subsequent pastries. When the concave grooves of the upper clamping plate 22 and the upper clamping plate 21 rotate counterclockwise to the upper part of the right conveyor 5, the lower clamping plate 22 rotates to the unfolded state. During the rotation, the second tooth 221 on its outer edge meshes with the lower connecting gear set 65. The lower connecting gear set 65 meshes with the small gear 64 near the right conveyor 5, causing the limiting rod 61 connected to it to rotate clockwise, opening the channel. This allows the pastry to be embedded in the concave groove of the upper clamping plate 21 under the conveying of the right conveyor 5. When the lower clamping plate 22 rotates clockwise and closes the concave groove, the second tooth 221 drives the limiting rod 61 to reverse and reset through the lower connecting gear set 65, intercepting the pastry and preventing scratches on the surface of the pastry caused by friction when the upper clamping plate 21 and the lower clamping plate 22 rotate. The merging mechanism 4 includes a left merging plate 41 installed at the end of the left conveyor 1, and a right merging plate 42 installed at the end of the right conveyor 5 on one side of the left merging plate 41. The edges of the left merging plate 41 and the right merging plate 42 are provided with concave grooves. The bottom ends of the left merging plate 41 and the right merging plate 42 are both equipped with a second gear 44, and a first gear 43 is connected to one side of the second gear 44. A third gear 45 is meshed on one side of the first gear 43. Reference Figures 13-15As shown, when various fillings for pastries are injected and need to be processed uniformly, such as during assembly and packaging, the two production lines are merged. A servo motor is installed at the bottom of the first gear 43. Starting the servo motor drives the first gear 43 to rotate, and the first gear 43 drives the third gear 45 to rotate synchronously, so that the two sets of second gears 44 connected by the pinion rotate synchronously. Through the design of the number of gears, the left and right assembly trays 41 and 42 rotate relative to each other. The edges of the left and right assembly trays 41 and 42 are provided with staggered concave grooves. Under the staggered rotation, the grooves embed the pastries continuously conveyed from the left conveyor 1 and right conveyor 5 one by one. When the groove rotates to the merging point at the single-sided conveyor 3, due to the difference in rotation between the left and right assembly trays 41 and 42, the pastries slide into the single-sided conveyor 3 under the constraint of the outlet, completing the merging and output of the pastries. The interval time between pastries can be precisely adjusted by adjusting the rotation speed, which is convenient for subsequent assembly and packaging and saves processing time.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
