DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] See also Figure 1-7 A dough slitting and rolling mechanism for a hand-pulled pancake production line includes a mounting frame 1 and a loading conveyor belt 21, an operating conveyor belt 22, and a unloading conveyor belt 23 which are assembled on the mounting frame 1 and arranged in sequence. The loading conveyor belt 21 and the operating conveyor belt 22 are arranged at the same horizontal height, and the unloading conveyor belt 23 is arranged below the operating conveyor belt 22.

[0040] It also includes a slitting assembly 3 arranged between the feeding conveyor belt 21 and the working conveyor belt 22. The slitting assembly 3 includes a cutting tool 31 and a telescopic cylinder A32. The telescopic cylinder A32 is fixedly installed on the mounting frame 1 and arranged in the vertical direction. The cutting tool 31 is fixedly connected to the movable end of the telescopic cylinder A32.

[0041] It also includes a roll assembly 4 arranged at the downstream end of the working conveyor belt 22. The roll assembly 4 includes a sliding bracket 41, a roll roller 42, and a telescopic cylinder B43. The sliding bracket 41 is installed on the mounting frame 1, the roll roller 42 is rotatably installed on the sliding bracket 41, the telescopic cylinder B43 is fixedly installed on the mounting frame 1, and the movable end of the telescopic cylinder B43 is fixedly connected to the sliding bracket 41.

[0042] The drive motor 5 is also included, and the drive motor 5 is in power connection with the loading conveyor belt 21 , the working conveyor belt 22 , the unloading conveyor belt 23 , and the winding roller 42 .

[0043] The setting of the mounting frame 1 enables the conveyor belts, slitting components 3, rolling components 4 and driving motor 5 to be stably mounted thereon, and the various components cooperate to realize the slitting and rolling operations of the noodles to meet the preliminary work of the production and processing of hand-pulled pancakes.

[0044] During operation, the dough sheets brushed with cooking oil are prevented from being transmitted on the feeding conveyor belt 21, so that they are stably transmitted along the feeding conveyor belt 21 and the working conveyor belt 22. During this process, the telescopic cylinder A32 drives the cutting tool 31 to move downward to cut the transmitted dough sheets into equal sizes. After cutting, the dough sheets of equal sizes are transmitted along the working conveyor belt 22.

[0045] When the dough sheet is transported to the downstream end of the working conveyor belt 22, the dough rolling assembly 4 starts to operate, and the telescopic cylinder B43 drives the sliding bracket 41 and the dough rolling roller 42 to resist each other at the downstream end of the working conveyor belt 22. The running dough rolling roller 42 acts on the dough sheet to roll the dough sheet into a strip structure. During this process, the telescopic cylinder B43 gradually drives the sliding bracket 41 and the dough rolling roller 42 to move backward. After the dough sheet is completely formed into a strip, it slides from the gap between the working conveyor belt 22 and the dough rolling roller 42, and is finally taken over by the unloading conveyor belt 23.

[0046] Afterwards, the telescopic cylinder B43 drives the winding roller 42 to return to the position against the downstream end of the operation conveyor belt 22 to perform the winding operation on the next face sheet.

[0047] In order to ensure that the loading conveyor belt 21, the operating conveyor belt 22, and the unloading conveyor belt 23 can be stably installed in the installation frame 1, and to ensure that each conveyor belt is driven by the driving motor 5 to operate stably, the following technical solution is provided.

[0049] The ends of the two groups of drive rollers 201 in the working conveyor belt 22 are both fixedly connected to the drive sprockets 203, and the two adjacent groups of drive sprockets 203 are chain-driven.

[0050] Each conveyor belt is connected to the conveyor belt 202 through two sets of transmission rollers 201, thereby ensuring the stable operation of the conveyor belt 202.

[0051] The transmission sprocket 203 in the feeding conveyor belt 21 and one group of transmission sprockets 203 in the working conveyor belt 22 realize chain transmission through a chain, and the other group of transmission sprockets 203 in the working conveyor belt 22 and the transmission sprocket 203 in the unloading conveyor belt 23 realize chain transmission through a chain. When the driving motor 5 drives the transmission roller 201 fixedly connected to it to operate, each conveyor belt 202 can realize stable transmission of hand-pulled pancake fabrics.

[0052] To ensure that the slitting assembly 3 can be stably assembled on the mounting frame 1, and to ensure that the slitting assembly 3 can effectively cut the conveyed dough sheets.

[0053] The mounting frame 1 is fixedly connected to a mounting plate A11 and a support pad 12.

The telescopic cylinder A32 is fixedly installed on the mounting plate A11. A knife groove vertically opposite to the cutting tool 31 is opened on the support pad 12.

[0054] The setting of the mounting plate A11 can ensure that the telescopic cylinder A32 is stably installed on it, and the support pad 12 can effectively support the dough sheets transmitted between the feeding conveyor belt 21 and the working conveyor belt 22, and the knife groove opened on it can prevent the falling cutting tool 31 from directly colliding with the support pad 12, thereby ensuring the sharpness of the blade of the cutting tool 31.

[0055] In order to ensure that the roll assembly 4 can be stably assembled on the mounting rack 1 and that the sliding bracket 41 can slide stably on the mounting rack 1, the following technical solution is provided.

[0056] The mounting frame 1 is fixedly connected to a mounting frame plate B13 and a guide shaft 14. A strip-shaped through hole 15 is opened on the side wall of the mounting frame 1. The sliding bracket 41 is slidably connected with the guide shaft 14. The telescopic cylinder B43 is fixedly installed on the mounting frame plate B13, and the end of the winding roller 42 is arranged in the strip-shaped through hole 15.

[0057] The setting of the mounting plate B13 can ensure the stable installation of the telescopic cylinder B43, the setting of the guide shaft 14 can ensure the stable sliding of the sliding bracket 41 along the length direction of the mounting frame 1, and the setting of the strip through hole 15 can avoid spatial movement interference between the rolling roller 42 and the side wall of the mounting frame 1.

[0058] In order to ensure that the winding roller 42 can be linked with the driving roller 201 in the working conveyor belt 22 and to ensure that the driving motor 5 can drive the winding roller 42 to operate stably when running, the following technical solution is provided.

[0059] A driving bevel gear A204 is fixedly connected to one group of transmission rollers 201 in the working transmission belt 22, and a transmission bevel gear A16 that is meshed with the driving bevel gear A204 is rotatably installed on the side wall of the mounting frame 1, and a spline shaft 17 is fixedly connected to the axis of the transmission bevel gear A16. A transmission bevel gear B411 that is slidably plugged into the spline shaft 17 is rotatably installed on the sliding bracket 41, and a driving bevel gear B412 that is meshed with the transmission bevel gear B411 is rotatably installed on the sliding bracket 41. A rotating sprocket 44 is fixedly connected to the axis of the winding roller 42 and the driving bevel gear B412, and the two groups of rotating sprockets 44 realize chain transmission through chains.

[0060] The combination of the spline shaft 17 and the transmission bevel gear B411 can ensure that when the sliding bracket 41 and the rolling roller 42 move along the length direction of the mounting frame 1, the power of the transmission bevel gear A16 can always be transmitted to the transmission bevel gear B411.

[0061] When the driving motor 5 drives the transmission roller to operate, the winding roller 42 is driven to operate stably through the driving bevel gear A204, the transmission bevel gear A16, the spline shaft 17, the transmission bevel gear B411, the driving bevel gear B412, and the rotating sprocket 44.

[0062] In order to prevent the dough sheet from sticking to the rolling roller 42 and affecting the rolling effect during the rolling process, the following technical solution is provided.

A plurality of groups of oil drip nozzles 453 are evenly installed at the bottom of the oil storage tank 451, and the oil drip nozzles 453 are arranged toward the oil brush 452.

[0064] The oil storage tank 451 stores cooking oil, which drips from the oil drip nozzle 453 and evenly falls on the oil brush 452. The oil brush 452 can evenly brush the dripping cooking oil on the rolling roller 42 so that the rolling roller 42 is covered with cooking oil, which can effectively prevent the back of the dough sheet (the unoiled side) from sticking to the rolling roller 42 and affecting the quality of the rolling.

[0065] Due to the height difference between the working conveyor belt 22 and the unloading conveyor belt 23, in order to ensure that the fabric after the roll surface treatment at the downstream end of the working conveyor belt 22 falls stably on the unloading conveyor belt 23, a material guide slope 18 is fixed in the mounting frame 1, and the two ends of the material guide slope 18 are opposite to the working conveyor belt 22 and the unloading conveyor belt 23 respectively.

[0066] After the fabric rolled into strips falls from the downstream end of the working conveyor belt 22, it slides along the guide slope 18 onto the unloading conveyor belt 23, enabling the unloading conveyor belt 23 to effectively receive the fabric strips and transport them to the downstream end.

[0067] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
