[0036] The present invention provides a dough sheet rolling machine, such as Figure 1 and Figure 2 As shown, the dough sheet rolling machine includes: a bracket 1, a rolling device 2, a driving device 3 and a positioning device. In the present embodiment, the dough sheet rolling machine includes a rolling device 2, a driving device 3 and a positioning device. The bracket 1 includes a support frame 11 and a support plate 12 fixed to the support frame 11, and the support plate 12 is in the form of a closed loop. In the present embodiment, the bracket 1 includes four parts, and the four parts are connected end to end to form a rectangle in a vertical plane, and the corners of the rectangle are rounded. The support plate 12 surrounds the bracket 1 and is arranged in contact with the outer wall of the support frame to form a rectangular ring. The rolling device 2 includes a rolling belt 21 in a closed loop surrounding the outer wall of the support plate 12 and a rolling forming component 22 cooperating with the rolling belt 21. In the present embodiment, the rolling belt 21 is also in the form of a rectangular ring. One section of the rolling belt 21 is used to carry the dough sheet 7, as shown in FIG. Figure 1 The figure shows a horizontal section of the rolling belt 21 located at the upper part. The rolling forming assembly 22 includes a sliding part 221 that can slide along the support plate 12 and a pick-up roller 222 installed on the sliding part 221. The pick-up roller 222 is horizontal and its axial direction is perpendicular to the sliding direction of the sliding part 221. The pick-up roller 222 can rotate relative to the sliding part 221. The pick-up roller 222 picks up a part of the rolling belt 21 from the support plate 12. When the pick-up roller 222 passes the rolling belt 21 where the dough sheet 7 is located, the part of the rolling belt 21 is picked up. The picked-up rolling belt 21 rolls up the dough sheet 7 and pushes the rolled dough roll to move. When the dough roll moves to the corner of the rectangle, it falls from the rolling belt 21 and is collected to proceed to the next procedure. In another embodiment, the support plate 12 can also be set to a triangle or a pentagon, and the rolling belt 21 is also triangular or pentagonal accordingly. In yet another embodiment, the support plate 12 has a horizontal section and a semicircular section located below the horizontal section and connected to the horizontal section. Correspondingly, the winding belt 21 also includes a horizontal section and a semicircular section.

[0037] The positioning device includes a first positioning component 4 and a second positioning component 5. The first positioning component 4 is located upstream of the dough sheet 7 to be rolled, and the second positioning component 5 is located downstream of the dough sheet 7 to be rolled. When the roll forming component 22 passes through the first positioning component 4, Figure 5 As shown, the second positioning assembly 5 positions the rolling belt 21 on the support plate 12. When the rolling forming assembly 22 passes through the second positioning assembly 5, as shown in FIG. Figure 4 As shown, the first positioning assembly 4 positions the rolling belt 21 on the support plate 12, so that the first positioning assembly 4 and the second positioning assembly 5 prevent the rolling belt 21 from sliding along the support plate 12. The driving device 3 can drive the rolling forming assembly 22 to move along the support plate 12, and the rolling forming assembly 22 can circulate along the support plate 12 one circle at a time, and complete a rolling action every time it moves one circle.

[0038] The dough sheet rolling machine of the present invention can automatically complete the rolling of the dough sheet 7 through the multi-circle circular movement of the rolling forming component 22. The staff only needs to make the dough sheet 7 between the first positioning component 4 and the second positioning component 5 before rolling, and the dough sheet rolling machine can complete the rolling, thereby freeing up a large amount of labor and improving the efficiency of rolling. At the same time, since the force of each rolling is the same, the shapes of all the rolled rolls can be guaranteed to be consistent to the greatest extent. In addition, the rolling forming component 22 only moves in one direction along the support plate 12, and there is no need to change the direction, so its operation is more reliable and efficient.

[0039] The curling and rolling forming assembly 22 further includes a curling roller 223 mounted on the sliding member 221 and rotatable relative to the sliding member 221. Figure 6 As shown, the curling roller 223 is parallel to the pick-up roller 222. In the up-down direction, the curling roller 223 is closer to the support plate 12, and in the sliding direction of the sliding member 221, the curling roller 223 is located upstream of the pick-up roller 222. The rolling belt 21 passes from the bottom of the curling roller 223 from downstream to upstream, extends downstream and upward until it passes over the pick-up roller 222 from above and then returns downward to the support plate 12. The curling roller 223 straightens the rolling belt 21 between the support plate 12 and the pick-up roller 222, and forms an angle between the portion of the rolling belt 21 that is attached to the support plate 12 and the portion of the rolling belt 21 that is wound between the curling roller 223 and the pick-up roller 222. The angle can further ensure the angle of the rolling, thereby further improving the consistency of the shape of the formed dough roll. In addition, in this embodiment, the curling roller 223 is detachably mounted on the sliding component 221, and the sliding component 221 can replace the curling roller 223 with different radii, so that the angle of the rolling belt 21 can be adjusted, thereby adjusting the tightness of the rolling.

[0040] As shown in FIG. 6 , the roll forming assembly 22 further includes a lower pressing roller 224 mounted on the sliding component 221 and rotatable relative to the sliding component 221. The lower pressing roller 224 is parallel to the lifting roller 222. The roll belt 21 passes over the lifting roller 222 and is pressed down to the support plate 12 by the lower pressing roller 224. The lower pressing roller 224 can limit the direction of the roll belt 21 and keep the roll belt 21 in a tensioned state, so that the roll action is more refined.

[0041] As shown in Figure 6, the sliding component 221 is provided with an adjustment groove 2214, the wall of the adjustment groove 2214 is provided with a threaded hole, the lifting roller 222 is located in the adjustment groove 2214, and the part of the lifting roller 222 located in the adjustment groove 2214 is provided with a threaded hole, and the rolling forming component 22 also includes an adjusting bolt 225, and the adjusting bolt 225 is respectively matched with the threaded hole of the adjustment groove 2214 and the threaded hole of the lifting roller 222 and adjusts the upper and lower positions of the lifting roller 222 relative to the curling roller 223 and the position in the sliding direction of the sliding component 221 by adjusting the matching position with the threaded hole of the adjustment groove 2214.

[0042] The sliding component 221 includes a horizontal portion 2211, a first inclined portion 2212 and a second inclined portion 2213. In the sliding direction of the sliding component 221, the first inclined portion 2212 extends from the horizontal portion 2211 downstream and upwardly inclined, and the second inclined portion 2213 extends from the first inclined portion 2212 upstream and upwardly inclined. The curling roller 223 and the lower pressure roller 224 are both provided on the horizontal portion 2211, and in the sliding direction of the sliding component 221, the curling roller 223 is located downstream of the lower pressure roller 224. The adjustment groove 2214 is provided on the second inclined portion 2213, and the extension direction of the adjustment groove 2214 is consistent with the extension direction of the second inclined portion 2213.

[0043] like Figure 3 As shown, the driving device 3 includes a motor 31 fixed to the bracket 1 and two groups of transmission mechanisms. Each group of transmission mechanisms includes a driving sprocket 32 ​​rotating under the drive of the motor 31, a chain 34 cooperating with the driving sprocket 32, and three driven sprockets 33 cooperating with the chains 34. In this embodiment, the driving sprocket 32 ​​and the driven sprocket 33 are arranged together to form a rectangle, and the chain 34 is in a rectangular ring shape. The two groups of transmission mechanisms are respectively installed on both sides of the bracket 1. The motor 31 synchronously drives the driving sprockets 32 of the two groups of transmission mechanisms. For example, the two driving sprockets 32 can be installed on the same driving shaft. The motor 31 drives the two driving sprockets 32 to rotate synchronously, so that the two chains 34 move synchronously. The two ends of the sliding component 221 are respectively connected to the two chains 34 and move under the drive of the chains 34. As shown Figure 3As shown, the support frame 11 is also provided with a chain 34 guide rail to guide the movement of the chain 34, so that the entire roll forming assembly 22 is driven to move reliably and stably along the rectangular ring through the sprocket and the chain 34, ensuring the stable roll forming. Of course, in other embodiments, each group of transmission mechanisms may include a driving sprocket 32 ​​and other number of driven sprockets 33, such as two driven sprockets 33, in which case the driving sprocket 32 ​​and the driven sprocket 33 are arranged together in a triangle, and the chain 34 is also in a triangle. When four driven sprockets 33 are used, the driving sprocket 32 ​​and the driven sprocket 33 can be arranged in a pentagon accordingly, and the chain 34 is also in a pentagon.

[0044] The first positioning assembly 4 and the second positioning assembly 5 both include a fixing part 41, 51 fixed to the support frame 11, a lifting part 42, 52 that can move up and down relative to the fixing device, a positioning drive device 43, 53 that drives the lifting parts 42, 52 to rise and fall, and a sensor 44, 54 for detecting the rolling and forming assembly 22; the dough sheet rolling machine also includes a control device (not shown in the figure), the sensor 44 of the first positioning assembly 4 and the sensor 54 of the second positioning assembly are both located between the fixing part 41 of the first positioning assembly and the fixing part 51 of the second positioning assembly, and the sensor 44 of the first positioning assembly 4 is located upstream of the sensor 54 of the second positioning assembly. When the dough sheet rolling machine 22 is moved upward and downward, the sensor 44 of the first positioning assembly 4 and the sensor 54 of the second positioning assembly are moved upward and downward, and the sensor 44 of the first positioning assembly 4 is moved upward and downward. When the control device receives the signal from the sensor 44 of the first positioning component 4 that detects the rolling and rolling forming component (at this time the rolling and rolling forming component has just passed the first positioning component 4), it controls the up and down driving device 44 of the first positioning component 4 to drive the lifting component 42 of the first positioning component 4 to descend to position the rolling belt 21 on the support plate 12, and maintains this state until the set time, then controls the up and down driving device 44 of the first positioning component 4 to drive the lifting component 42 of the first positioning component 4 to rise, or it can also control the up and down driving device 44 of the first positioning component 4 to drive the lifting component 42 of the first positioning component 4 to rise according to the number of revolutions of the motor 31, at which time the rolling and rolling forming component 22 runs to the vicinity of the upstream of the first positioning component 4. When the control device receives the signal from the sensor 54 of the second positioning component 5 that the roll forming component 22 is detected (at this time, the roll forming component 22 is about to reach the second positioning component 5), the up-down driving device 54 of the second positioning component 5 is controlled to drive the lifting component 52 of the second positioning component 5 to rise to allow the roll forming component 22 to pass through and maintain this state until the set time, and then the up-down driving device 54 of the second positioning component 5 is controlled to drive the lifting component 52 of the second positioning component 5 to descend, or the up-down driving device 54 of the second positioning component 5 can be controlled to drive the lifting component 52 of the second positioning component 5 to descend according to the number of revolutions of the motor 31. At this time, the roll forming component 22 runs to the vicinity of the upstream of the first positioning component 4, and the lifting component 42 of the first positioning component 4 is about to rise. The descent of the lifting component 52 of the second positioning component 5 is earlier than the rise of the lifting component 42 of the first positioning component 4, ensuring that the roll belt 21 is always positioned. The time period or the number of revolutions of the motor is the set condition.

[0045] like Figure 1 and Figure 3As shown, the fixing component 41 includes a vertical fixing plate 411, and the fixing plate 411 is perpendicular to the length direction of the support plate 12. The fixing component 41 also includes two support legs 412 located on both sides of the rolling belt 21, and the upper ends of the support legs 412 are connected to the lower ends of the fixing plates 411. In this embodiment, the support legs 412 are formed by extending downward from both sides of the fixing plates 411. The two support legs 412 are respectively fixed to the support frame 11, and a space is formed between the lower end of the fixing plate 411 and the rolling belt 21 to allow the rolling forming assembly 22 to pass through. The positioning drive device 433 can drive the lifting component 42 to reciprocate up and down. The lifting component 42 can move upward to make way for the passing space, and the lifting component 42 can move downward to block the passing space and press the rolling belt 21 onto the support plate 12. The positioning drive device 433 can be a cylinder, a hydraulic cylinder or an electric cylinder. In this embodiment, a cylinder is selected, and its piston rod is downward. The lifting component 42 is a positioning plate fixed to the lower end of the piston rod. When the rolling forming component 22 approaches, the positioning plate rises under the drive of the cylinder, allowing the rolling forming component 22 to pass. After the rolling forming component 22 leaves, the positioning plate descends under the drive of the cylinder to press the rolling belt 21 onto the support plate 12.

The negative pressure pump 61 makes the negative pressure box body 62 have negative pressure, and forms adsorption on the dough sheet 7 to be rolled on the rolling belt 21, so as to prevent the dough sheet 7 from sliding relative to the rolling belt 21 under the push of the rolling belt 21 during rolling, so that the rolling can be completed at the set position, the rolling action is more precise, and the finished product rate of the rolling is improved. In this embodiment, different covers are provided as the upper wall of the negative pressure box body 62, and the shapes and areas of the adsorption through holes of different covers are different, thereby improving the adaptability to dough sheets of different shapes and sizes, so that the dough sheets are more firmly adsorbed, and the rolling yield rate is further improved. After the rolling is completed, the rolled dough sheet 7 is located at the end of the adsorption area, and is no longer adsorbed, but rolls to the set position under the push of the rolling belt 21 to enter the next program.

[0047] In another embodiment, the dough sheet rolling machine includes a plurality of rolling devices 2 and positioning devices corresponding to the plurality of rolling devices 2, and the rolling belts 21 of all the rolling devices 2 are parallel.
