Description

Technical Field

[0001] This utility model relates to the field of stacking machine technology, specifically to a double-sided powder-sprinkling stacking machine. Background Technology

[0002] The dough produced by the dough mixer is relatively thick. To press the thick dough to the required thickness and then fold it, a dough folding machine is needed.

[0003] Currently, existing dough stacking machines include a pressing device and a stacking device. The pressing device includes two pressing rods, and a second motor drives the pressing rods to rotate. Thick dough sheets are pressed thinner after passing between the two pressing rods. The thickness of the pressed dough sheets is adjusted by changing the distance between the two pressing rods. The stacking device includes a conveyor frame and a dough tray. A track is provided below the pressing device, and a conveyor frame is provided on the track. The conveyor frame is driven by a second motor to move back and forth on the track. The dough tray is placed on the conveyor frame. Dough sheets of the required thickness are pressed out by the pressing device and fall onto the dough tray below. The stacking is completed by moving the dough tray back and forth.

[0004] In the above solution, after the dough sheets are stacked on the tray, the staff needs to tear them apart, which is not only time-consuming and laborious, but also results in uneven edges. In addition, when stacking the dough sheets, in order to prevent them from sticking together, powder needs to be sprinkled on both the top and bottom surfaces of the dough sheets. However, the traditional method is mostly to manually sprinkle powder on the dough sheets, and even some mechanized methods are relatively crude methods of sprinkling powder, which are not efficient and the powder is not easy to sprinkle evenly. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a double-sided powdering and layering machine. By providing a cutting component, the dough can be cut, and by providing a powdering mechanism, powder can be evenly applied to both sides of the dough. This solves the problems of manual tearing of the dough and uneven powdering in the prior art, thereby improving work efficiency and ensuring that the layered dough does not stick together.

[0006] The solution of this utility model to the aforementioned technical problem is:

[0007] A double-sided powder-spreading and stacking machine includes a frame, on which a placement rack, a first belt conveyor, a second belt conveyor, two sets of pressing devices, and a stacking device are mounted. The pressing device includes two pressing rollers and a drive mechanism, and the stacking device includes a placement tray and a reciprocating moving assembly. Two sets of powder-spreading mechanisms and a cutting assembly are provided on the side wall of the frame. One set of powder-spreading mechanisms is located on the left side of the first belt conveyor, and the other set of powder-spreading mechanisms is located on the right side of the second belt conveyor. The cutting assembly is located above the placement tray.

[0008] When thick dough needs to be pressed into the required thickness and folded, the unloading roller with the thick dough wrapped around it is placed on the top of the placement frame. The dough is released, passing sequentially between the two pressing rollers of the two pressing devices, between the first belt conveyor and one of the powder-spreading mechanisms, between the second belt conveyor and the other powder-spreading mechanism, and then between the cutting components. Finally, it is placed on the top of the placement tray. The first belt conveyor, the second belt conveyor, and the drive mechanism are then activated to transport the dough and rotate one of the pressing rollers. The dough, under the action of the pressing roller, drives another pressing roller to rotate, so that the dough is squeezed as it passes between the two pressing rollers. Thus, the dough can be squeezed into the required thickness through two sets of pressing devices. Then, the reciprocating moving component is activated, which drives the placing tray to move back and forth continuously, so that the dough of the required thickness can be folded up. Under the action of two sets of powdering mechanisms, powder is evenly sprinkled on both sides of the dough, so as to ensure that the folded dough pieces do not stick together. After the dough pieces are folded, the cutting component is activated to cut the dough pieces, so that the workers can easily transport the folded dough pieces to other places.

[0009] By incorporating a cutting component, the dough can be cut, and by incorporating a powder-sprinkling mechanism, powder can be evenly sprinkled on both sides of the dough. This solves the problems of existing technologies where workers need to manually tear the dough and the powder is not evenly sprinkled, thereby improving work efficiency and ensuring that the stacked dough pieces do not stick together.

[0010] The utility model is further configured such that: the reciprocating moving component includes two slide rails symmetrically fixed to the bottom of the frame and a first motor; the lower end of the placement plate is fixed with a plurality of sliders that cooperate with the slide rails; the bottom of the frame is rotatably connected to two pulleys; the two pulleys are equipped with the same belt; the belt is fixed to the lower end of the placement plate; and one of the pulleys is fixed to the output end of the first motor.

[0011] With the above technical solution, when it is necessary to drive the placement tray to move back and forth continuously, the first motor is controlled to rotate back and forth, thereby driving one of the pulleys to rotate back and forth, which in turn drives the other pulley to rotate back and forth via the belt. At the same time, the belt can be driven to move back and forth, thereby driving the placement tray to move back and forth continuously.

[0012] The utility model is further configured such that: the powder dispensing mechanism includes a powder storage box, an adjustment component and an opening and closing component, the upper end of the powder storage box is formed with a slot, a box cover is inserted into the slot, a first powder outlet plate is fixed on the inner wall of the powder storage box, a dispersing roller is rotatably connected inside the powder storage box, the dispersing roller abuts against the upper end of the first powder outlet plate, a second motor is fixed on the side wall of the powder storage box, and one end of the dispersing roller is fixed on the output end of the second motor.

[0013] The above technical solution allows for evenly sprinkling flour on both sides of the dough. The lid is opened, a certain amount of flour is poured into the flour storage box, the lid is closed, and the second motor is started to rotate the dispersing roller, thus dispersing the flour in the storage box and preventing it from accumulating and failing to drain through the gap in the first flour discharge plate. The opening and closing mechanism is controlled to open, allowing the flour to drain through the gap in the first flour discharge plate. The amount of flour discharged is adjusted by the regulating component. When the dough passes under the flour storage box, the flour will drain through the gap in the first flour discharge plate and fall evenly onto one side of the dough. As the dough continues to be conveyed through another set of flour-sprinkling mechanisms, the flour can fall evenly onto the other side of the dough, thus achieving even sprinkling on both sides of the dough.

[0014] The utility model is further configured such that: the adjusting component includes a second powder outlet plate inserted into the side wall of the powder storage box, the upper end of the second powder outlet plate abutting against the lower end of the first powder outlet plate, and a handle is fixed on the side wall of the second powder outlet plate.

[0015] With the above technical solution, by providing a second flour discharge plate, when flour needs to be discharged, it must pass through the gap between the first and second flour discharge plates simultaneously. Therefore, when it is necessary to adjust the flour discharge rate, the second flour discharge plate can be moved by a handle to adjust the size of the gap between the first and second flour discharge plates, thereby adjusting the flour discharge rate.

[0016] The utility model is further configured such that: the opening and closing component includes a powder baffle plate rotatably connected to the lower end of the powder storage box, a connecting frame rotatably connected to the side wall of the powder baffle plate, the other end of the connecting frame rotatably connected to the side wall of the powder storage box, a sleeve fixed to the side wall of the powder storage box, and a stop rod inserted into the sleeve.

[0017] With the above technical solution, when flour needs to be discharged, the operator moves the connecting frame downwards, causing the powder baffle to rotate outwards. The connecting frame is then placed on one side of the powder storage box, allowing the flour to be discharged. When it is necessary to stop discharging flour, the operator moves the connecting frame upwards, causing the powder baffle to rotate inwards and abut against the lower end of the powder storage box, thus stopping the flour discharge. The stop rod is then inserted into the sleeve, abutting against the lower end of the connecting frame, preventing the connecting frame from moving downwards under gravity.

[0018] The utility model is further configured such that: the cutting assembly includes a cylinder fixed to the lower end of the frame, a first shearing block is fixed to the end of the cylinder's push rod, and a second shearing block is fixed to the lower end of the frame and is offset from the first shearing block.

[0019] Using the above technical solution, the dough is placed on the top of the placement tray after passing between the first and second cutting blocks. When the dough needs to be cut after being stacked, the cylinder is activated to move the first cutting block, and under the action of the second cutting block, the dough located between the first and second cutting blocks can be cut.

[0020] The utility model is further configured such that a brush is provided on one side of the powder-spreading mechanism, and the brush is fixed to the side wall of the frame.

[0021] With the above technical solution, after the powdering mechanism sprinkles powder on the surface of the dough, it can brush off the excess flour on the surface of the dough by means of a brush, thus preventing waste caused by too much flour.

[0022] The beneficial effects of this utility model are:

[0023] Compared with existing technologies, this invention features a cutting component that allows the dough to be cut and a powder-sprinkling mechanism that allows powder to be evenly sprinkled on both sides of the dough. This solves the problems of existing technologies, such as the need for workers to manually tear the dough and uneven powder application, thereby improving work efficiency and ensuring that the stacked dough pieces do not stick together.

[0024] The dough is equipped with a brush, which allows excess flour to be brushed off the surface of the dough. Attached Figure Description

Detailed Implementation

[0031] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0032] The following is for reference Figures 1 to 5 This utility model will now be described.

[0033] A double-sided powder-spreading and stacking machine includes a frame 1, on which a placement rack 2, a first belt conveyor 3, a second belt conveyor 4, two sets of pressing devices and a stacking device are mounted. The pressing device includes two pressing rollers 5 and a drive mechanism 6. The stacking device includes a placement tray 7 and a reciprocating moving assembly. Two sets of powder-spreading mechanisms and a cutting assembly are provided on the side wall of the frame 1. One set of powder-spreading mechanisms is located on the left side of the first belt conveyor 3, and the other set of powder-spreading mechanisms is located on the right side of the second belt conveyor 4. The cutting assembly is located above the placement tray 7.

[0034] When a thick dough sheet 8 needs to be pressed into the required thickness and folded, the feeding roller with the thick dough sheet 8 wound on it is placed on the upper end of the placement frame 2, and the dough sheet 8 is released. The dough sheet 8 passes sequentially between the two pressing rollers 5 of the two pressing devices, between the first belt conveyor 3 and one of the powder-spreading mechanisms, between the second belt conveyor 4 and the other powder-spreading mechanism, and then between the cutting components. Finally, it is placed on the upper end of the placement tray 7. The first belt conveyor 3, the second belt conveyor 4, and the drive mechanism 6 are started to transport the dough sheet 8 and rotate one of the pressing rollers 5. Under the action of the dough sheet 8, another pressing roller 5 is driven to rotate, so that the dough sheet 8 is squeezed when passing between the two pressing rollers 5. Thus, the dough sheet 8 can be squeezed into the required thickness through the two sets of pressing devices. The reciprocating moving component is activated, which drives the placing tray 7 to move back and forth continuously, so that the dough sheet 8 of the required thickness can be folded up. Under the action of the two sets of powdering mechanism, powder is evenly sprinkled on both sides of the dough sheet 8, so as to ensure that the folded dough sheets 8 do not stick together. After the dough sheet 8 is folded, the cutting component is activated to cut the dough sheet 8, so that the staff can easily carry the folded dough sheet 8 to other places.

[0035] By incorporating a cutting component, the dough sheet 8 can be cut. By incorporating a powder-sprinkling mechanism, powder can be evenly sprinkled on both sides of the dough sheet 8. This solves the problems of existing technologies where workers need to manually tear the dough sheet 8 and the powder-sprinkling is not uniform, thereby improving work efficiency and ensuring that the stacked dough sheets 8 do not stick together.

[0036] The reciprocating motion assembly includes two slide rails 9 symmetrically fixed to the bottom of the frame 1 and a first motor 10. The lower end of the placement plate 7 is fixed with multiple sliders 11 that cooperate with the slide rails 9. The bottom of the frame 1 is rotatably connected to two pulleys 12. The same belt 13 is installed on the two pulleys 12. The belt 13 is fixed to the lower end of the placement plate 7. One of the pulleys 12 is fixed to the output end of the first motor 10.

[0037] When it is necessary to drive the placement tray 7 to move back and forth continuously, the first motor 10 is controlled to rotate back and forth, thereby driving one of the pulleys 12 to rotate back and forth. The rotation of one pulley 12 drives the other pulley 12 to rotate back and forth via the belt 13, and at the same time, the belt 13 can be driven to move back and forth, thereby driving the placement tray 7 to move back and forth continuously.

[0038] The powder dispensing mechanism includes a powder storage box 14, an adjustment component, and an opening and closing component. The upper end of the powder storage box 14 has a slot 1401 formed therein, and a box cover 15 is inserted into the slot 1401. A first powder outlet plate 16 is fixed on the inner wall of the powder storage box 14. A dispersing roller 17 is rotatably connected inside the powder storage box 14. The dispersing roller 17 abuts against the upper end of the first powder outlet plate 16. A second motor 18 is fixed on the side wall of the powder storage box 14, and one end of the dispersing roller 17 is fixed on the output end of the second motor 18.

[0039] When it is necessary to evenly sprinkle flour on both sides of the dough sheet 8, open the lid 15, pour a certain amount of flour into the flour storage box 14, close the lid 15, start the second motor 18, drive the dispersing roller 17 to rotate, thereby dispersing the flour in the flour storage box 14 to prevent the flour from accumulating and not being able to be discharged from the gap of the first flour discharge plate 16. Control the opening and closing component to open, so that the flour can be discharged through the gap of the first flour discharge plate 16. Adjust the amount of flour discharged by adjusting the component. When the dough sheet 8 passes under the flour storage box 14, the flour will be discharged through the gap of the first flour discharge plate 16 and fall evenly on one side of the dough sheet 8. When the dough sheet 8 continues to be conveyed through another set of flour sprinkling mechanisms, the flour can fall evenly on the other side of the dough sheet 8, so that the flour can be evenly sprinkled on both sides of the dough sheet 8.

[0040] The adjustment assembly includes a second powder outlet plate 19 that is inserted into the side wall of the powder storage box 14. The upper end of the second powder outlet plate 19 abuts against the lower end of the first powder outlet plate 16. A handle 20 is fixed on the side wall of the second powder outlet plate 19.

[0041] By providing a second flour discharge plate 19, when flour needs to be discharged, it must pass through the gap between the first flour discharge plate 16 and the second flour discharge plate 19 simultaneously. Therefore, when it is necessary to adjust the amount of flour discharged, the second flour discharge plate 19 is moved by the handle 20 to adjust the size of the gap between the first flour discharge plate 16 and the second flour discharge plate 19, thereby adjusting the amount of flour discharged.

[0042] The opening and closing assembly includes a powder baffle 21 rotatably connected to the lower end of the powder storage box 14. A connecting frame 22 is rotatably connected to the side wall of the powder baffle 21. The other end of the connecting frame 22 is rotatably connected to the side wall of the powder storage box 14. A sleeve 23 is fixed to the side wall of the powder storage box 14. A stop bar 24 is inserted into the sleeve 23.

[0043] When flour needs to be discharged, the operator moves the connecting frame 22 downwards, causing the powder baffle 21 to rotate outwards. The connecting frame 22 is then placed on one side of the powder storage box 14, allowing the flour to be discharged. When it is necessary to stop discharging flour, the operator moves the connecting frame 22 upwards, causing the powder baffle 21 to rotate inwards and abut against the lower end of the powder storage box 14, thus stopping the flour discharge. The baffle rod 24 is then inserted into the sleeve 23, abutting against the lower end of the connecting frame 22, preventing the connecting frame 22 from moving downwards under gravity.

[0044] The cutting assembly includes a cylinder 25 fixed to the lower end of the frame 1, a first shearing block 26 fixed to the end of the push rod of the cylinder 25, and a second shearing block 27 fixed to the lower end of the frame 1, which is offset from the first shearing block 26.

[0045] After the dough sheet 8 passes between the first cutting block 26 and the second cutting block 27, it is placed on the top of the placement tray 7. After the dough sheet 8 is stacked, when it is necessary to cut the dough sheet 8, the cylinder 25 is activated to move the first cutting block 26. Under the action of the second cutting block 27, the dough sheet 8 located between the first cutting block 26 and the second cutting block 27 can be cut.

[0046] A brush 28 is provided on one side of the powder-spreading mechanism and is fixed to the side wall of the frame 1.

[0047] After the powdering mechanism sprinkles powder on the surface of the dough 8, the brush 28 can brush away the excess powder on the surface of the dough 8, preventing waste caused by too much powder.

[0048] Working principle:

[0049] When it is necessary to press the thick dough sheet 8 into the required thickness and fold it, open the lid 15, pour a certain amount of flour into the flour storage box 14, close the lid 15, start the second motor 18, drive the dispersing roller 17 to rotate, thereby dispersing the flour in the flour storage box 14, place the feeding roller with the thick dough sheet 8 on the upper end of the placement frame 2, and release the dough sheet 8, so that the dough sheet 8 passes sequentially between the two pressing rollers 5 of the two sets of pressing devices, between the first belt conveyor device 3 and one of the flour storage boxes 14, and the second... The extended end between the belt conveyor 4 and another powder storage box 14, after passing between the first shearing block 26 and the second shearing block 27, is placed on the upper end of the placement tray 7. The operator moves the connecting frame 22 downwards, causing the powder baffle 21 to rotate outwards and the connecting frame 22 to be placed on one side of the powder storage box 14, thus releasing the flour and evenly distributing it onto the surface of the dough sheet 8. The handle 20 moves the second powder outlet plate 19, adjusting the first powder outlet plate 16 and... The size of the gap between the second powder discharge plates 19 is adjusted to regulate the amount of flour discharged. The first belt conveyor 3, the second belt conveyor 4, and the drive mechanism 6 are activated to transport the dough sheet 8 and drive one of the pressing rollers 5 to rotate. At the same time, under the action of the dough sheet 8, the other pressing roller 5 is driven to rotate, so that the dough sheet 8 is squeezed when passing between the two pressing rollers 5. Thus, the dough sheet 8 can be squeezed into the required thickness through the two sets of pressing devices. The first motor 10 is controlled to rotate back and forth, thereby driving one of the pulleys 12 to rotate back and forth. The rotation of one pulley 12 drives the other pulley 12 to rotate back and forth through the belt 13. At the same time, the belt 13 can move back and forth, thereby driving the placement tray 7 to move back and forth continuously and fold the dough sheet 8 of the required thickness. After the dough sheet 8 is folded, the cylinder 25 is activated to drive the first shearing block 26 to move. Under the action of the second shearing block 27, the dough sheet 8 is cut, so that the workers can easily transport the folded dough sheet 8 to other places.

[0050] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
