[0001] The utility model belongs to the field of food processing technology and equipment, and more specifically relates to a calendering, cutting and anti-sticking and diffusion integrated machine, which is used in the calendering and cutting stage of high-water-added noodle product processing. Background Art

[0002] Rolling and slitting is a crucial step in noodle processing and a key factor in determining noodle appearance and quality. During the slitting process, dough sheets formed from high-water-addition dough are prone to sticking to the equipment, sticking and tangling between noodles, and uneven cross-sections after slitting. This not only affects noodle quality but also hinders the development of automated production of high-water-addition noodles. Currently, my country lacks suitable rolling and slitting equipment suitable for high-water-addition dough production. Utility Model Content

[0004] The technical solutions adopted are as follows:

[0005] A calendering, slitting and anti-sticking diffusion integrated machine includes a frame and a first-level calendering roller group, a second-level calendering roller group, a slitting knife group, a noodle line diffusion flow plate and a control device installed on the frame, the first-level calendering roller group is arranged above the second-level calendering roller group, the slitting knife group is arranged below the second-level calendering roller group, the noodle line diffusion flow plate is located at the lower discharge end of the slitting knife group, and the first-level calendering roller group and the second-level calendering roller group are respectively composed of a pair of calendering rollers, the calendering gap formed by the second-level calendering roller group is smaller than the calendering gap formed by the first-level calendering roller group, and the noodle line diffusion flow plate is an arc-shaped plate arranged downwardly at an angle; the control device independently controls the operation of the first-level calendering roller group, the second-level calendering roller group and the slitting knife group.

[0006] Preferably, the noodle line diffusion flow plate is a trapezoidal curved surface that is narrow at the top and wide at the bottom. A plurality of widening grooves are evenly distributed from top to bottom on the surface of the noodle line diffusion flow plate that fits the cut noodles, and a gap for air flow is formed between the cut noodles and the widening grooves.

[0007] Furthermore, air blowers are provided at the upper and lower ends of the surface line diffusion flow plate, respectively, for forcibly blowing air into the widened slot.

[0008] Preferably, the slitting knife group is a group of counter-rotating toothed rollers.

[0009] Furthermore, one side of the first-stage calendering roller group and the second-stage calendering roller group is respectively provided with a manual adjustment mechanism for adjusting the corresponding calendering gap size.

[0010] Furthermore, the first-level calendering roller group and the second-level calendering roller group are both cylindrical rollers with smooth surfaces, and an encoder and a laser ranging device are respectively provided on their corresponding rotating shafts. The encoder is connected to the control device and is used to detect the operating speed of the first-level calendering roller group and the second-level calendering roller group in real time, and the laser ranging device is used to detect the size of the corresponding calendering gap in real time.

[0011] Furthermore, the outer layers of the first-stage calendering roller group and the second-stage calendering roller group are coated with a food-grade polytetrafluoroethylene anti-sticking material layer.

[0012] The technical solution of this utility model has the following advantages:

The calendering rollers are preferably made of food-grade polytetrafluoroethylene anti-stick material, which can effectively solve the problem of high-moisture noodle strips sticking to the equipment. After cutting, the noodles fall onto the curved noodle diffusion flow plate, which can effectively prevent the noodles from sticking together.

[0014] B. The present invention allows the cut noodles to fall onto a noodle diffusion plate. By providing a plurality of variable-width slots and air diffusers on the plate, the noodle diffusion plate blows and diffuses air, causing the cross-section of the cut noodles to quickly evaporate moisture while simultaneously diffusing the noodles, thereby solving the problem of noodles sticking together after cutting.

[0015] C. The number of grooves in the noodle line diffusion flow plate of this utility model is designed according to the strip width of the cutter and is designed and manufactured using 3D printing to meet the requirements of rapid and synchronous replacement with the cutter.

[0016] D. The utility model provides an encoder for detecting the rotational speed of the calendering rollers and a laser distance measuring device for accurately detecting the calendering gap on the two-stage calendering roller group. Through precise laser distance measurement, the calendering ratio of each stage and the corresponding rotational speed are calculated.

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.

[0028] like Figure 1 and Figure 2As shown, the utility model provides a calendering, slitting and anti-sticking diffusion all-in-one machine, including a frame 1 and a first-level calendering roller group 2, a second-level calendering roller group 3, a slitting knife group 4, a noodle line diffusion flow plate 5 and a control device (not shown in the figure) installed on the frame 1, the first-level calendering roller group 2 is arranged above the second-level calendering roller group 3, the slitting knife group 4 is arranged below the second-level calendering roller group 3, the noodle line diffusion flow plate 5 is located at the discharge end below the slitting knife group 4, and the first-level calendering roller group 2 and the second-level calendering roller group 3 are respectively composed of a pair of horizontally placed calendering rollers I and calendering rollers II, and the calendering gap formed by the second-level calendering roller group 3 is smaller than the calendering gap formed by the first-level calendering roller group 2. The dough sheet enters from the upper part of the frame 1, and is calendered twice by the first-level calendering roller group 2 and the second-level calendering roller group 3 in sequence to be thinned to the required thickness. The dough sheet is calendered once by the first-level calendering roller group 2, for example, the thickness is changed from 2.0 mm to 1.5 mm, and then is calendered twice by the calendering rollers I and II in the second-level calendering roller group 3. The thickness of the dough sheet after the second calendering is 1.25 mm.

[0029] The surface line diffusion flow plate 5 used in the present invention is an arc-shaped plate arranged at an angle downward; independent frequency conversion motors are respectively arranged on the first-level calendering roller group 2, the second-level calendering roller group 3 and the slitting knife group 4, and the control device is electrically connected to each frequency conversion motor to independently control the operating speed of the first-level calendering roller group 2, the second-level calendering roller group 3 and the slitting knife group 4.

[0030] As a further preferred embodiment of the present invention, both the primary calendering roller set 2 and the secondary calendering roller set 3 are smooth cylindrical rollers. Their corresponding rotating shafts are equipped with an encoder 7 and a laser distance measuring device 8, respectively. The encoder 7 is connected to a control device and is used to detect the operating speed of the primary calendering roller set 2 and the secondary calendering roller set 3 in real time. The laser distance measuring device 8 is used to detect the size of the corresponding calendering gap in real time. The laser distance measuring device 8 enables precise distance measurement and calculates the calendering ratio of each level. For example, the calendering ratio of the primary calendering roller set 2 is 25%, and the calendering ratio of the secondary calendering roller set 3 is 16.7%. Each pair of calendering rollers is arranged horizontally, with the dough sheet moving from top to bottom. They are independently driven by variable frequency drives, and the encoders accurately calculate the speed, achieving precise speed matching and control of the three reduction motors. The corresponding calendering rollers in the primary calendering roller set 2 and the secondary calendering roller set 3 are preferably 127 mm in diameter and 550 mm in width.

[0031] As a further preferred embodiment of the present invention, a manual adjustment mechanism for adjusting the thickness of the dough strip is installed on the same side of the first-stage calendering roller group 2 and the second-stage calendering roller group 3, which is used to adjust the calendering gap between the calendering roller I and the calendering roller II in each stage of the calendering roller group, so as to achieve manual adjustment of the dough strip thickness. Figure 5 and Figure 6As shown, the manual adjustment mechanism 6 includes an adjusting handwheel 61, a transmission device 62, a transmission shaft 63 and a pull rod 64. A pull rod 64 is installed on the bearing seats at both ends of the calendering roller II. Two transmission devices 62 are set on the transmission shaft 63. The rotating shaft connected to the adjusting handwheel 61 is connected to the transmission shaft 63. The two pull rods 64 are connected to the transmission devices 62 respectively. By rotating the adjusting handwheel 61 forward and reverse, the transmission shaft 63 rotates forward and reverse synchronously. The transmission shaft 63 drives the pull rod 64 to move forward and backward through the transmission device 62. The two pull rods 64 then pull the bearing seats at both ends of the calendering roller II to move synchronously, thereby adjusting the calendering gap between the calendering roller I and the calendering roller II.

[0032] The noodle diffusion plate 5 used in the present invention adopts an arc-shaped structure. When the cut noodles fall onto its upper surface, a gap will naturally form between adjacent noodles. The edges of the noodles are affected by the air in the environment and will not cause sticking problems. Figure 3 As shown, the preferred noodle diffuser plate 5 of the present invention is a trapezoidal curved surface that is narrow at the top and wide at the bottom. Several variable-width grooves 51 are evenly distributed on the surface of the noodle diffuser plate 5, which aligns with the cut noodles. A gap for air flow is formed between the cut noodles and the variable-width grooves 51. As the cut noodles slide downward across the noodle diffuser plate 5, a tiny gap is formed during their sliding, facilitating air flow. The noodles diffuse along the variable-width grooves 51, preferably over a width of 550 mm to 650 mm.

[0033] As a further preferred embodiment of the present invention, Figure 2 and Figure 4 As shown, the present invention features slow forced-air diffusers 9 at the upper and lower ends of the noodle diffuser 5. These diffusers force air into the variable-width slots 51, rapidly evaporating moisture from the noodle cutouts. This prevents noodle sticking and stranding, creating favorable conditions for subsequent drying and dehydration. The noodle diffuser 5 in the present invention is preferably manufactured using 3D printing, though other fabrication methods are also possible.

[0034] As a further preferred embodiment of the present invention, the slitting knife group 4 used in the present invention is a group of counter-rotating toothed rollers, preferably 550 mm in width, placed horizontally, and independently driven by variable frequency, suitable for various knife types.

[0035] In order to further prevent the problem of adhesion between noodles and the calendering roller, the utility model is coated with a food-grade polytetrafluoroethylene anti-sticking material layer on the outer layer of the calendering roller, which is suitable for calendering noodles with a moisture content greater than 34% and a noodle thickness of 1-3mm.

[0036] The rolled dough sheet enters the strip cutting stage and is cut into noodles of the required cross-sectional size by the strip cutting knife group 4; the noodles are diffused along the noodle line diffusion flow plate 5 and output to the subsequent processing steps.

[0037] Any matters not described in this utility model are applicable to the prior art.

[0038] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
