[0002] A complete rice noodle production line includes the collaborative operation of several or even dozens of devices. The optimization and improvement of any device will bring huge changes to the current production situation. During the production of rice noodles, due to different requirements of different customers for product specifications, the specification parameters of the product are mainly thickness, width and length. Ensuring different parameters involves different devices.

[0003] During the production of rice noodles, the quantification of width is mainly completed by a strip cutting device. The main component for determining the width of rice noodles in the strip cutting device is the cutter roll.

[0004] The cutter roll of the traditional strip cutting device is mainly integrally processed from round steel. This integrally formed cutter roll structure is continuously widened under the increasing production volume, resulting in an increasing cumulative tolerance in the fit between the cutter roll grooves. In order to make the cutter grooves of the two cutter rolls mesh with each other, the accuracy requirements for the processing equipment are getting higher and higher, resulting in larger and larger processing equipment that can process such wide cutter rolls, higher and higher accuracy requirements, and continuously rising processing costs. Content of the Utility Model

[0005] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a strip cutting device with a segmented assembled cutter roll, which can reduce the influence of the assembly accuracy of the cutter roll, reduce the processing difficulty of the cutter roll, and reduce the cost.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A strip cutting device with a segmented assembled cutter roll includes a fixed frame, a power main shaft, a plurality of power segmented cutter rolls, a power gear, a driven main shaft, a plurality of driven segmented cutter rolls, a driven gear and a transmission device;

[0008] The power main shaft and the driven main shaft are arranged in parallel on the fixed frame, and both ends of the transmission device are respectively connected to the power main shaft and the driven main shaft to make the power main shaft and the driven main shaft rotate towards each other;

[0009] A plurality of power segmented cutter rolls are sequentially sleeved on the power main shaft, a plurality of driven segmented cutter rolls are sequentially sleeved on the driven main shaft, the plurality of power segmented cutter rolls and the plurality of driven segmented cutter rolls are arranged in one-to-one correspondence, and a strip cutting space is formed between each power segmented cutter roll and the corresponding driven segmented cutter roll;

[0010] Tolerance compensation pads are arranged between adjacent power segmented cutter rolls and between adjacent driven segmented cutter rolls, and the width of the tolerance compensation pad is equal to the cumulative tolerance in the fit between the power segmented cutter roll and the driven segmented cutter roll.

[0011] Further, the transmission device includes a driving gear and a driven gear, the driving gear and the driven gear are respectively sleeved on the driving main shaft and the driven main shaft, and the driving gear and the driven gear are in meshing transmission.

[0012] Further, a sprocket for driving rotation is provided on the driving main shaft.

[0013] Further, locking nuts are sleeved on both the driving main shaft and the driven main shaft, which are respectively used to lock the driving segmented cutter roller and the driven segmented cutter roller.

[0014] Further, a fixed bearing seat and a bearing seat with a slider are provided on the fixing frame, the driving main shaft and the driven main shaft respectively pass through the fixed bearing seat and the bearing seat with a slider, a compression spring is provided between the fixed bearing seat and the bearing seat with a slider, and a distance adjusting device is provided on the fixing frame for adjusting the distance between the driving segmented cutter roller and the driven segmented cutter roller.

[0016] Further, a scraper group for cleaning the driving segmented cutter roller and the driven segmented cutter roller is provided on the fixing frame.

[0017] Generally speaking, the utility model has the following advantages:

Tolerance compensation pads are provided between adjacent driving segmented cutter rollers and between adjacent driven segmented cutter rollers. The width of the tolerance compensation pad is equal to the cumulative tolerance of the fit between the previous driving segmented cutter roller and the driven segmented cutter roller, which can eliminate the cumulative tolerance of the fit between the driving segmented cutter roller and the driven segmented cutter roller, enabling the subsequent driving segmented cutter roller and the driven segmented cutter roller to be fitted on the basis of nearly zero tolerance, reducing the influence of the cumulative tolerance on the overall knife roller assembly, and at the same time reducing the processing difficulty of the knife roller and the cost; in addition, since the knife roller is a consumable part, only the external knife roller needs to be replaced when the edge of the assembled knife roller is damaged, avoiding unnecessary waste caused by overall replacement.

[0033] The following will further elaborate on the present utility model in detail.

[0034] As Figures 1-6 shown, a strip cutting device with segmented assembly of cutter rollers includes a fixing bracket 3, a power cutter roller group 1, a driven cutter roller group 2, a transmission device, a tolerance compensation pad 5, and a compression spring 4.

[0035] The power cutter roller group 1 includes a power main shaft 11, a plurality of power segmented cutter rollers 12, and a power gear 13.

[0036] The driven cutter roller group 2 includes a driven main shaft 21, a plurality of driven segmented cutter rollers 22, and a driven gear 23.

[0037] The power main shaft 11 and the driven main shaft 21 are arranged in parallel side by side on the fixing bracket 3, and both ends of the transmission device are respectively connected to the power main shaft 11 and the driven main shaft 21 to make the power main shaft 11 and the driven main shaft 21 rotate towards each other;

[0038] A plurality of power segmented cutter rollers 12 are sequentially sleeved on the power main shaft 11, and a plurality of driven segmented cutter rollers 22 are sequentially sleeved on the driven main shaft 21. The plurality of power segmented cutter rollers 12 and the plurality of driven segmented cutter rollers 22 are arranged in one-to-one correspondence, and a strip cutting space is formed between each power segmented cutter roller 12 and the corresponding driven segmented cutter roller 22;

[0039] Tolerance compensation pads 5 are provided between adjacent power segmented cutter rollers 12 and between adjacent driven segmented cutter rollers 22. The width of the tolerance compensation pad 5 is equal to the cumulative tolerance of the fit between the power segmented cutter roller 12 and the driven segmented cutter roller 22.

[0040] Specifically, a sprocket 15 is provided on the power main shaft 11, and the sprocket 15 is driven to rotate by an external power motor (not shown in the figure). The sprocket 15 rotates and drives the power main shaft 11 to rotate through a flat key. A plurality of power segmented cutter rollers 12 are sequentially arranged on the power main shaft 11. The power main shaft 11 and the power segmented cutter roller 12 are connected by a spline. The power main shaft 11 rotates and completes the power output to the power segmented cutter roller 12 through the spline, and the power segmented cutter roller 12 performs continuous circular motion.

[0041] In this embodiment, the transmission device includes a power gear 13 and a driven gear 23. The power gear 13 and the driven gear 23 have the same number of teeth and modulus, and are respectively sleeved on the power main shaft 11 and the driven main shaft 21, and the power gear 13 and the driven gear 23 are meshed for transmission.

[0042] After the power main shaft 11 rotates, it transmits torque to the power gear 13 through a flat key to complete driving the power gear 13 to rotate. The power gear 13 inputs torque to the driven gear 23 to complete the reverse rotation of the driven gear 23 and the driven main shaft 21. At the same time, it drives the driven segmented cutter roller 22 on the driven main shaft 21 to rotate through a spline, and completes the opposite and inward rotation of the power segmented cutter roller 12 and the driven segmented cutter roller 22.

[0043] Locking nuts 6 are threadedly connected to both the power main shaft 11 and the driven main shaft 21, respectively for locking the power segmented cutter roller 12 and the driven segmented cutter roller 22.

[0044] A fixed bearing seat 14 and a slider-bearing seat 24 are provided on the fixed frame 3. The power main shaft 11 and the driven main shaft 21 respectively pass through the fixed bearing seat 14 and the slider-bearing seat 24. A compression spring 4 is provided between the fixed bearing seat 14 and the slider-bearing seat 24. The compression spring 4 is in a compressed state, and its two ends respectively abut against the fixed bearing seat 14 and the slider-bearing seat 24, and always maintains an outward thrust on the driven cutter roller group 2. A distance adjusting device is provided on the fixed frame 3 for adjusting the distance between the power segmented cutter roller 12 and the driven segmented cutter roller 22.

[0045] Specifically, a base 31 is provided at the lower end of the fixing frame 3. Cross braces 34 are respectively provided on both sides of the base 31. A top plate 32 and a bottom plate 33 are provided at the upper end. Both the top plate 32 and the bottom plate 33 are provided with a right-angled U-shaped groove. The two grooves are arranged oppositely to form a limiting and guiding cavity. The slider of the slider bearing block 24 slides linearly in the limiting and guiding cavity. End plates 35 are fixedly provided on the side parts at both ends of the fixing frame 3. There are threaded holes on the end plates 35. The distance adjusting device is an adjusting screw 36. The adjusting screw 36 passes through the end plate 35 inwardly and is connected to the slider bearing block 24. The extending direction of the adjusting screw 36 is parallel to the compression spring 4. The adjusting screw 36 is adjusted inwardly and outwardly through the thread to complete the position limitation of the driven cutter roller group 2, and realize the adjustment of the cutting depth between the power segmented cutter roller 12 and the driven segmented cutter roller 22.

[0046] A scraper group 7 for cleaning the power segmented cutter roller 12 and the driven segmented cutter roller 22 is also provided on the fixing frame 3.

[0047] During operation, the rice noodles to be cut are introduced into the cutter roller grooves that rotate inwards towards each other. The rice noodles are cut under the extrusion with the roller cutter groove gap adjusted. The scraper group 7 adjusts the scraper to enter the cutter groove of the cutting roller through the scraper seat. Every time the cutter roller rotates one circle, the scraper group 7 cleans the residual materials in the roller cutter groove once, keeping the cutting device clean during operation.

[0048] The utility model has the following advantages:

[0049] 1. For the power cutter roller group 1 and the driven cutter roller group 2 on the cutting device, under the outward thrust of the compression spring 4, when adjusting the roller cutter groove gap of the driven cutter roller group 2, only need to loosen or tighten the adjusting screw 36 to complete, which is simple, economical and effective.

[0050] 2. The segmented roller cutters on the cutting device are installed on the main shaft by an assembled method. After the cutter grooves of each segment of the cutter roller are engaged, the tolerance compensation is completed through the tolerance compensation block. Each segment of the segmented roller cutter is an independent unit, with less mutual influence, avoiding the problem that the accumulated tolerance in the cooperation of an integrally processed long roller cutter leads to difficult misaligned meshing of the cutter grooves, indirectly reducing the processing accuracy requirements. At the same time, triangular grooves are processed on the convex surface of the cutter groove on the segmented cutter roller, reducing the contact surface between the cutter surface and the material when the cutting edge cuts the material, and avoiding the tool deflection phenomenon caused by excessive contact between the cutter groove and the material.

[0051] 3. The segmented installation enables the width of the cutting device to be completed only by adding the number of segments of the roller cutter in a modular way. The segmented cutter roller can be mass-produced as a standard part.

[0052] The production of the equal-width strip cutting device with a 4-segment installation enables the production of strip cutting devices of different specifications only by changing the width of the knife grooves of the segmented knife roller. All parts of the whole strip cutting device are the same except for the change of the knife roller, which is convenient for production. When the knife grooves are damaged and maintained, only the damaged segmented knife roller needs to be replaced, reducing the use cost.

[0053] The above embodiments are the preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and shall be included in the protection scope of the present invention.
