Description

TECHNICAL FIELD

[0001] The application relates to the technical field of dough sheeters, in particular to a dough sheeter with a gap fine-tuning locking mechanism and a use method thereof. BACKGROUND

[0002] In the field of dough processing, a dough sheeter is a key device for realizing dough rolling and forming. Its core function is to repeatedly roll the dough through a pair of counter-rotating conveying rollers, and finally produce a dough sheet with uniform thickness and compact texture. In this process, the gap between the two conveying rollers determines the final thickness of the dough sheet, so the accurate adjustment and stable maintenance of the gap are important indicators to measure the performance of the dough sheeter. Traditional dough sheeters usually use a manual screw rod combined with a scale dial to adjust the gap, and are fixed by a mechanical locking device. However, in actual production, especially in continuous operation, equipment vibration, reaction force when the dough passes through, and slight deformation of the locking mechanism may all cause the preset gap to drift, affecting the uniformity of the product thickness. In addition, to prevent sticking, the dough sheet surface often needs to be dusted during the dough pressing process. The existing dusting structure is mostly a fixed powder box or a vibrating screen. When processing dough with high water content for a long time, the flour is prone to dampening and caking and blocking at the powder box screen, resulting in uneven dusting or even interruption, which not only affects the quality of the dough pressing, but also requires frequent manual cleaning, seriously restricting the production efficiency and automation level. Flour blocking occurs from time to time, causing dusting to be interrupted and requiring frequent manual cleaning, which not only increases labor intensity but also reduces production efficiency, so a dough sheeter with a gap fine-tuning locking mechanism and a use method thereof are proposed to solve the problems raised in the above. SUMMARY

[0004] The application provides a dough sheeter with a gap fine-tuning locking mechanism and a use method thereof, which adopts the following technical scheme: A dough sheeter with a gap fine-tuning locking mechanism, comprising a machine body, a lower conveying structure, an upper conveying structure, a guide roller and a dusting structure arranged inside the machine body, a driving mechanism arranged on the outer wall of the machine body for driving the lower conveying structure, the upper conveying structure and the guide roller; A linkage mechanism, a boosting assembly and a knocking assembly are arranged on the machine body in cooperation, wherein a clutch assembly cooperating with the upper conveying structure is arranged on the linkage mechanism, and the boosting assembly and the knocking assembly are driven for use through the cooperation of the clutch assembly and the upper conveying structure; The pressurization assembly includes a pressurization component, which includes a pressurization cylinder, a piston slidably disposed inside the pressurization cylinder, and a connecting plate fixed to the end of the piston. A return spring is installed between the connecting plate and the pressurization cylinder. The pressurizing assembly also includes an air supply pipe disposed between the pressurizing component and the striking component. The striking component includes a striking component and a main pipe disposed outside the powder-spreading structure. The two ends of the air supply pipe are fixedly connected to the pressurizing cylinder and the main pipe, respectively. The striking component includes a hollow mounting cylinder and a striking block slidably disposed within the mounting cylinder. A connecting pipe is fixed between the outer wall of the mounting cylinder and the main pipe.

[0005] Optionally: the number of guide rollers is two, the upper conveying structure is inclined, the upper conveying structure includes a conveying component, and an adjustment frame is provided on the outside of the conveying component. An adjustment groove for fine adjustment of the conveying component is provided inside the machine body to cooperate with the adjustment frame.

[0006] Optionally: The two guide rollers are distributed vertically at the same end of the lower conveying structure and the upper conveying structure, and a baffle is fixed to the top side of the machine body by bolts.

[0007] Optionally, the linkage mechanism further includes an abutting component and a reciprocating component, and the abutting component achieves lifting and lowering adjustment through the reciprocating component; the abutting component includes a frame with a U-shaped shape disposed above the upper conveying structure, an abutting roller is installed on the inner bearing of the frame, a guide component penetrating the interior of the baffle is disposed above the frame, and an eccentric wheel is fixed at one end of the abutting roller to abut against the connecting plate in the pressurizing component.

[0008] Optionally: The clutch assembly includes a clutch element and a connecting arm disposed between the clutch element and the reciprocating assembly; the clutch element includes a clutch seat, a rotor disposed inside the clutch seat, and a centrifugal block, wherein a linkage shaft fixed inside the rotor and fixed to the end of the roller on the conveying component is provided, and an mounting sleeve is sleeved outside the linkage shaft, wherein a connecting rod is hinged between the mounting sleeve and the centrifugal block.

[0009] Optionally: the centrifugal block is slidably connected to the inside of the rotor, the mounting sleeve is composed of two rotating sleeves, and a return spring is installed on the outer wall of one of the sliding sleeves and the outer wall of the centrifugal block, and one side of the connecting arm is fixed to the outer wall of the other rotating sleeve.

[0010] Optionally: A limiting rod extending to the outside of the mounting cylinder is fixed on the outer wall of the striking block, and there are multiple striking parts, which are linearly and equidistantly distributed outside the powder-spreading structure.

[0011] Optional: The reciprocating assembly includes a reciprocating plate slidably installed inside the machine body. The reciprocating plate has an inclined guide groove inside. A guide wheel that is rotatably connected to the outer wall of the frame is rolled inside the guide groove. The powder-spreading structure is bolted to the outer wall of the reciprocating plate.

[0012] Optionally, the reciprocating assembly further includes a guide block and a mating block, wherein the guide block is fixed to the outer wall of the reciprocating plate, the mating block is fixed to the top side of the connecting plate, and the guide block and the mating block each have an inclined surface for abutting mating on opposite sides.

[0013] Another problem that this invention also needs to solve is to provide a method of using a dough press with a gap fine-tuning locking mechanism, including the following steps: S1. Preparations before powering on: Check that all parts are intact, and add enough flour to the flouring structure; S2, Start-up and pressing: Once the drive mechanism is started and the equipment reaches its operating speed, the clutch assembly activates, automatically disengaging and releasing the lock, causing the upper conveying structure to enter a floating pressure surface state. The dough is placed into the lower conveyor structure and rolled into a sheet by the lower conveyor structure, the upper conveyor structure, and the conveyor rollers. S3, Sprinkle with powder: The powder-spreading structure is activated to evenly spread powder on the dough. At the same time, the rotation speed of the upper conveyor structure increases, thereby driving the clutch component to work. The linkage mechanism automatically triggers two actions. First, the abutting roller presses down to fit the upper conveyor structure. After the abutting roller fits, the eccentric wheel triggers the pressurization component to generate airflow to drive the striking component to strike the powder-spreading structure, preventing the powder-spreading structure from clogging. Repeat step 3, and the device will automatically unlock and enter working mode.

[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. In this invention, when the upper conveying structure is in operation, the linkage shaft drives the rotor to rotate. As the rotation speed changes, the centrifugal block slides inside the rotor under the action of centrifugal force, overcoming the elastic force of the return spring, thus achieving clutch engagement with the upper conveying structure. The structure design that uses centrifugal force to achieve clutch engagement is novel and unique. It does not require additional complex control devices and can automatically control the clutch engagement based solely on the operating state of the equipment itself. This ensures stable operation of the equipment at different working stages, simplifies the operation process, and reduces the equipment failure rate.

[0015] 2. In this invention, when the eccentric wheel at one end of the abutting roller pushes the connecting plate, the piston slides and compresses air in the pressurizing cylinder, generating airflow to start the striking component. Due to the multi-point distribution and limiting design of the striking components, the powder-spreading structure can be struck comprehensively and evenly, effectively preventing flour from clogging in the powder-spreading structure and ensuring the uniformity of powder spreading.

[0016] 3. In this invention, when the connecting plate moves, the reciprocating plate can be pushed to move through the abutting action of the inclined surface, which further realizes the linkage between the pressurizing component and the reciprocating component. The inclined surface abutting design is simple in structure, but can effectively transmit power and realize the coordinated work between different components. Attached Figure Description

[0019] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0020] like Figures 1 to 8As shown, a dough press with a gap fine-tuning locking mechanism in this embodiment includes a machine body 1, a lower conveying structure 2, an upper conveying structure 3, guide rollers 4, and a powder-spreading structure 6 disposed inside the machine body 1. A drive mechanism 5 for driving the lower conveying structure 2, the upper conveying structure 3, and the guide rollers 4 is provided on the outer wall of the machine body 1. It should be noted that there are two guide rollers 4. The upper conveying structure 3 is inclined and includes a conveying component 31. An adjustment frame 32 is provided on the outside of the conveying component 31. An adjustment groove 33 is provided inside the machine body 1 to cooperate with the adjustment frame 32 for fine-tuning of the conveying component 31. The two guide rollers 4 are distributed vertically at the same end of the lower conveying structure 2 and the upper conveying structure 3. One of the guide rollers 4 is slidably disposed, which can be adjusted for gap. After the guide roller 4 is adjusted, it is locked and fixed by a plug rod. A stop frame 12 is bolted to the top side of the machine body 1.

[0021] To further clarify, the powder-sprinkling structure 6 can adopt an existing and publicly reproducible structure. In use, the drive mechanism 5 is activated, which drives the lower conveyor structure 2, the upper conveyor structure 3, and the guide rollers 4 to begin operation. The dough is placed at the starting end of the lower conveyor structure 2. Under the action of the drive mechanism 5, the dough moves forward with the lower conveyor structure 2. When the dough reaches the space between the lower and upper conveyor structures 2, the gap between them has been precisely adjusted according to the dough thickness requirements. Under the pressure between the two structures, the dough is gradually pressed into a sheet. Simultaneously, the two guide rollers 4 guide the dough smoothly through the conveying channel, ensuring the dough remains stable during transport without shifting or wrinkling. The dough passes through the guide rollers 4 and is introduced into the upper conveyor structure 3 for transport, then falls into the lower conveyor structure 2 for further transport. In this way, the pressing effect can be repeatedly achieved.

[0022] To improve the flour-spreading effect, the machine body 1 is equipped with a linkage mechanism, a pressure boosting component 9, and a striking component 11. The linkage mechanism includes a clutch component 8 that works in conjunction with the upper conveyor structure 3. The clutch component 8, in conjunction with the upper conveyor structure 3, drives the pressure boosting component 9 and the striking component 11. It should be noted that the pressure boosting component 9 provides more stable and stronger pressure for the flour-spreading process. Through the linkage mechanism and the upper conveyor structure 3, when the upper conveyor structure 3 is operating, the clutch component 8 triggers the pressure boosting component 9, which in turn activates the striking component 11 to strike the exterior of the flour-spreading structure 6. This allows the flour-spreading structure 6 to spray flour more evenly onto the dough surface, while also preventing clogging of the flour-spreading structure 6. It is worth mentioning that, under the action of the linkage mechanism, the tapping component 11 can tap the powder-spreading structure 6 in a timely manner according to the operating status of the upper conveying structure 3. When the powder-spreading structure 6 shows signs of flour blockage, the tapping action of the tapping component 11 can loosen the blocked flour and discharge it smoothly, ensuring the smooth flow of the powder-spreading channel, thereby continuously and stably carrying out the powder-spreading work and further improving the powder-spreading effect. Furthermore, the automatic operation of the pressurizing component 9 and the striking component 11 is achieved through the cooperation of the clutch assembly 8 and the upper conveying structure 3. Operators only need to activate the upper conveying structure 3, and the entire powder-spreading system will automatically start working according to the preset program, without the need for manual activation or adjustment of the pressurizing and striking devices. This greatly simplifies the operation process and reduces the difficulty of operation.

[0023] The pressurizing assembly 9 in this example includes a pressurizing component 91, which comprises a pressurizing cylinder 911, a piston 912 slidably disposed inside the pressurizing cylinder 911, and a connecting plate 917 fixed to the end of the piston 912. A return spring 913 is installed between the connecting plate 917 and the pressurizing cylinder 911. After the piston 912 completes one pressurizing action, the return spring 913 automatically resets the piston, preparing it for the next pressurization, thus ensuring the continuity and stability of the pressurization process. The pressurizing assembly 9 also includes an air supply pipe 92 disposed between the pressurizing component 91 and the striking assembly 11. It should be noted that the pressurization level can be flexibly adjusted by adjusting the movement distance of the piston 912 within the pressurizing cylinder 911. Operators can precisely control the stroke of the piston 912 according to different dough types, thicknesses, and processing requirements, enabling the dough press to adapt to various production needs and improving the equipment's versatility.

[0024] In this embodiment, the striking component 11 includes a striking element 111 and a main pipe 112 disposed outside the powder-spreading structure 6. The two ends of the gas supply pipe 92 are fixedly connected to the pressurizing cylinder 911 and the main pipe 112, respectively. Specifically, the striking element 111 includes a hollow mounting cylinder 1111 and a striking block 1112 slidably disposed within the mounting cylinder 1111. A connecting pipe 1113 is fixed between the outer wall of the mounting cylinder 1111 and the main pipe 112. In use, the striking block 1112 in the striking element 111 slides within the mounting cylinder 1111 and impacts the powder-spreading structure 6 under gas pressure, generating vibration. This vibration effectively loosens and discharges the flour clogged within the powder-spreading structure 6, preventing powder spreading interruptions or uneven spreading due to flour blockage, thus ensuring the smooth progress of the powder spreading process.

[0025] It should be noted that a limiting rod 1114 extending to the outside of the mounting cylinder 1111 is fixed on the outer wall of the striking block 1112. There are multiple striking elements 111, and these multiple striking elements 111 are linearly and equidistantly distributed outside the powder-spreading structure 6. It should also be noted that the mounting cylinder 1111 serves as a guide cavity, and the striking block 1112 is slidably disposed inside the mounting cylinder 1111. Driven by airflow, it is propelled outward to strike the powder-spreading structure 6. The limiting rod 1114 is fixed to the outer wall of the striking block 1112 and extends outward from the mounting cylinder 1111. This arrangement not only prevents the striking block 1112 from completely detaching but also allows for a direct visual display of its operating status.

[0026] The linkage mechanism in this embodiment also includes an abutting component 7 and a reciprocating component 10, and the abutting component 7 achieves lifting and lowering adjustment through the reciprocating component 10; the abutting component 7 includes a frame 71 with a U-shaped shape, which is set above the upper conveying structure 3. An abutting roller 72 is installed on the inner bearing of the frame 71. A guide 73 that penetrates the interior of the baffle 12 is set above the frame 71. An eccentric wheel 74 that abuts against the connecting plate 917 in the pressurizing component 91 is fixed at one end of the abutting roller 72; it should be noted that the key to the setting of the eccentric wheel 74 is that its outline is not a perfect circle. Therefore, when the abutting roller 72 descends with the frame 71, the protruding part of the eccentric wheel 74 will press against the connecting plate 917 at the front end of the pressurizing component 91, thereby triggering the pressurizing action.

[0027] The clutch assembly 8 includes a clutch element 81 and a connecting arm 82 disposed between the clutch element 81 and the reciprocating assembly 10; the clutch element 81 includes a clutch seat 811, a rotor 812 disposed inside the clutch seat 811 and a centrifugal block 814, the rotor 812 has a linkage shaft fixed inside and fixed to the end of the roller on the conveying component 31, and the linkage shaft is fitted with an installation sleeve 813, wherein the installation sleeve 813 and the centrifugal block 814 are hinged to a connecting rod 815.

[0028] The centrifugal block 814 is internally slidably connected to the rotor 812. The mounting sleeve 813 consists of two rotating sleeves, and a return spring 816 is installed on the outer wall of one of the sliding sleeves and the outer wall of the centrifugal block 814. One spring acts on the centrifugal block 814, and the other acts on one of the rotating sleeves, together providing elastic force to reset the centrifugal block 814 and pull back the mounting sleeve 813. One side of the connecting arm 82 is fixed to the outer wall of the other rotating sleeve. Therefore, when the equipment speed changes, the sliding of the centrifugal block 814 drives the mounting sleeve 813 to move axially through the connecting rod 815, which in turn drives the connecting arm 82 to push and pull, thereby realizing power output.

[0029] In this embodiment, the reciprocating assembly 10 includes a reciprocating plate 101 slidably installed inside the machine body 1. The reciprocating plate 101 has an inclined guide groove 102 inside. A guide wheel 103, rotatably connected to the outer wall of the frame 71, is rolled along the inner side of the guide groove 102. When the connecting arm 82 pulls the reciprocating plate 101 horizontally, the inclined guide groove 102 wall forces the guide wheel 103 and the connected frame 71 to move vertically, thus precisely converting the horizontal reciprocating motion into vertical lifting motion, controlling the pressing and releasing of the abutment roller 72. It should be noted that the powder-spreading structure 6 is bolted to the outer wall of the reciprocating plate 101. During operation of the reciprocating assembly 10, the powder-spreading structure 6 can automatically adjust its position to accurately spread powder onto the dough. After the reciprocating assembly 10 is finished, the powder-spreading structure 6 can be moved to the side, facilitating maintenance and powder replenishment by staff. Specifically, the reciprocating assembly 10 also includes a guide block 104 and a mating block 105. The guide block 104 is fixed to the outer wall of the reciprocating plate 101, and the mating block 105 is fixed to the top side of the connecting plate 917. The guide block 104 and the mating block 105 are provided with abutting inclined surfaces 106 on opposite sides. When the reciprocating assembly 10 is finished, the abutting assembly 7 disengages from driving the booster assembly 9. At this time, the booster assembly 9 is restarted by moving the reciprocating plate 101 through the mating inclined surfaces 106, which can further improve the anti-clogging of the powder spreading structure 6.

[0030] Another problem that this invention also needs to solve is to provide a method of using a dough press with a gap fine-tuning locking mechanism, including the following steps: S1. Preparations before powering on: Check that all parts are intact, and add enough flour to the flouring structure 6; S2, Start-up and pressing: When the drive mechanism 5 is started and the equipment reaches the working speed, the clutch component 8 is activated and automatically released from the lock, and the upper conveying structure 3 enters the floating pressure surface state. The dough is placed into the lower conveyor structure 2 and rolled into a sheet by the lower conveyor structure 2, the upper conveyor structure 3 and the guide roller 4. S3, Sprinkle with powder: The powder-spreading structure 3 is activated to evenly spread powder on the dough. At the same time, the rotation speed of the upper conveyor structure 3 is increased, thereby driving the clutch assembly 8 to work. The linkage mechanism automatically triggers two actions. First, the abutting roller 72 presses down and adheres to the upper conveyor structure 3. After the abutting roller 72 adheres, the eccentric wheel 74 triggers the pressurizing assembly 9, which generates airflow to drive the striking piece 111 to strike the powder-spreading structure 6, preventing the powder-spreading structure 6 from becoming blocked. Repeat step 3, and the device will automatically unlock and enter working mode.

[0031] Combined with appendix Figures 1-8 The working principle of the above embodiments is as follows: After the drive mechanism 5 is started, the lower conveyor structure 2, the upper conveyor structure 3 and the two guide rollers 4 work together. The dough is placed at the starting end of the lower conveyor structure 2 and is conveyed to the gap of the upper conveyor structure 3. The gap has been precisely manually fine-tuned and locked in the position of the adjusting frame 32 in the adjusting groove 33. The dough is rolled into the initial dough sheet here. After the dough sheet passes through the guide rollers 4, it enters the conveying path of the upper conveyor structure 3 and then falls back to the starting end of the lower conveyor structure 2 to form a cycle, realizing multiple pressing of the dough to achieve the ideal thickness and texture of the dough sheet. Throughout the pressing process, the powder-sprinkling structure 6 sprinkles powder onto the dough surface to prevent sticking. When powder is sprinkled, power is transmitted to the rotor 812 of the clutch assembly 8 via the linkage shaft. The centrifugal force generated by the high-speed rotation of the rotor 812 causes the internal centrifugal block 814 to slide outward against the elastic force of the return spring 816. The radial movement of the centrifugal block 814 is converted into the axial movement of the mounting sleeve 813 via the connecting rod 815, which in turn drives the connecting arm 82 fixed thereto to move. The connecting arm 82 pulls or pushes the reciprocating plate 101 of the reciprocating assembly 10 to perform horizontal reciprocating motion. The inclined guide groove 102 opened inside the reciprocating plate 101 cooperates with the guide wheel 103 on the abutment assembly 7, driving the frame 71 together with the abutment roller 72 to descend. As the abutment roller 72 descends, the eccentric wheel 74 fixed at one end rotates with the shaft. When the protruding part of the eccentric wheel 74 rotates to the bottom, it squeezes the connecting plate 917 in the pressurizing assembly 9, pushing the piston 912 to compress air in the pressurizing cylinder 911, overcoming the resistance of the return spring 913, and completing one pressurization. The compressed air is delivered to each striking piece 111 through the air supply pipe 92 and the main pipe 112, and then through the connecting pipe 1113. The high-pressure airflow drives the striking block 1112 to rush out quickly in the mounting cylinder 1111, violently striking the outer wall of the powder-spreading structure 6, shaking off the clumps of flour to prevent blockage, thus achieving dynamic and uniform powder spreading.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.

The reciprocating plate (101) has an inclined guide groove (102) inside. A guide wheel (103) is rotatably connected to the outer wall of the frame (71) on the inner side of the guide groove (102). The powder spreading structure (6) is bolted to the outer wall of the reciprocating plate (101).

9. A dough press with a gap fine-tuning locking mechanism according to claim 8, characterized in that: The reciprocating assembly (10) further includes a guide block (104) and a mating block (105), wherein the guide block (104) is fixed on the outer wall of the reciprocating plate (101), the mating block (105) is fixed on the top side of the connecting plate (917), and the guide block (104) and the mating block (105) are provided with abutting slopes (106) on opposite sides.

10. A method of using a dough press with a gap fine-tuning locking mechanism, referring to the dough press with a gap fine-tuning locking mechanism as described in any one of claims 1-9, comprising the following steps: S1. Preparations before powering on: Check that all parts are intact, and add enough flour to the flouring structure (6); S2, Start-up and pressing: Start the drive mechanism (5). After the equipment reaches the working speed, the clutch assembly (8) will be activated and automatically released from the lock. The upper conveying structure (3) will enter the floating pressure surface state. The dough is placed into the lower conveyor structure (2) and rolled into a dough sheet by the lower conveyor structure (2), the upper conveyor structure (3) and the conveyor roller (4); S3, Sprinkle with powder: Start the powder spreading structure (3) to evenly spread powder on the dough. At the same time, the rotation speed of the upper conveying structure (3) increases, thereby driving the clutch assembly (8) to work. The linkage mechanism automatically triggers two actions. First, the abutting roller (72) presses down and adheres to the upper conveying structure (3). After the abutting roller (72) adheres, the eccentric wheel (74) triggers the booster assembly (9) to generate airflow to drive the knocking piece (111) to knock on the powder spreading structure (6) to prevent the powder spreading structure (6) from clogging. Repeat step 3, and the device will automatically unlock and enter working mode.
