Description

Technical Field

[0001] This utility model belongs to the technical field of roller device, specifically, it relates to a biscuit cutting and forming roller device. Background Technology

[0002] In the biscuit production process, the roller device is a crucial step in achieving biscuit shaping and cutting. Traditional biscuit cutting and shaping roller devices typically employ a single roller cutting mold or roller blade structure, using the rotation of the roller and the action of the blade to cut the biscuit dough into shape. While this design meets the needs of biscuit production to some extent, it has several problems in practical application. First, biscuits tend to stick to the roller surface during the cutting process, leading to uneven cutting and affecting product quality. This is especially true for dough with high moisture content, where adhesion is more severe, easily producing dough crumbs, which further affects the biscuit shaping effect. Second, the traditional device is complex to adjust the cutting shape and size, and changing molds is difficult, making it hard to adapt to the production needs of biscuits of different sizes and shapes. For example, changing molds in traditional roller cutting and shaping mechanisms requires disassembling multiple parts, which is cumbersome, and the mold components cannot be quickly disassembled and cleaned, affecting production efficiency. In addition, traditional devices can usually only perform a single cutting or shaping operation, unable to meet the needs of multiple biscuit production simultaneously, resulting in limited functionality. These problems limit the efficiency and flexibility of biscuit production, increase production costs, and also affect product diversity and quality.

[0003] With the ever-changing market demands, consumers are placing higher requirements on the variety, shape, and quality of cookies. Therefore, developing a novel cookie cutting and forming roller device that can effectively address these issues is particularly important. An ideal device should possess advantages such as reduced adhesion, flexible adjustment of cutting shape and size, improved production efficiency, multi-functionality, and simple structure to meet the diverse needs of modern cookie production. Based on this market demand and technological background, this invention proposes an innovative cookie cutting and forming roller device. It aims to overcome the shortcomings of traditional devices by improving the device's structural design, thereby achieving efficient, flexible, and high-quality cookie production. Utility Model Content

[0004] In view of this, the present invention provides a biscuit cutting and forming roller device, which solves the problem of uneven cutting and low production efficiency caused by adhesion in traditional biscuit cutting and forming roller devices.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a biscuit cutting and forming roller device, including a roller, the roller being fixed by a frame, a conveyor shaft being provided at the bottom of the roller, and a rolling shaft being provided at the bottom of the conveyor shaft. The rolling shaft is used to drive the conveyor shaft to rotate, thereby driving the roller to rotate. The roller includes:

[0007] A vent roller includes a hollow roller body, multiple retractable vent needles, a spring mechanism, an adjusting plate, and an adjusting screw. The vent needles are connected to the adjusting plate inside the roller body via the spring mechanism. The adjusting plate can be rotated by an external adjusting screw. The adjusting plate is provided with grooves of different depths, and the bottom of the vent needle is located in the groove. As the adjusting plate rotates, the vent needle extends or retracts to the surface of the roller body under the action of the spring.

[0008] The slitting and forming roller includes two nested rollers, an inner roller and an outer roller. The inner roller has a basic slitting edge on its surface. The outer roller is a rotatable adjusting ring with a slitting groove that mates with the inner roller's cutting edge. The outer roller is connected to an adjusting nut via a threaded connection. Rotating the adjusting nut allows the outer roller to move axially, thereby changing the relative position of the slitting groove and the inner roller's cutting edge.

[0009] The technical advantages of the biscuit slitting and forming roller device provided by this utility model are as follows: The ventilated roller, through its retractable ventilating needles, can generate a micro-airflow when the biscuit passes through the roller, reducing adhesion between the biscuit and the roller surface, preventing the biscuit surface from being stretched and deformed during the slitting process, and improving the appearance quality of the biscuit. The slitting and forming roller, through the cooperation of inner and outer rollers, can flexibly adjust the slitting shape and size to adapt to the production needs of biscuits of different specifications, improving the versatility and flexibility of the device.

[0010] Based on the above technical solution, the biscuit cutting and forming roller device of this utility model can be further improved as follows:

[0011] In the initial state, all the air-permeable needles extend out of the surface of the roller body.

[0012] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: In the initial state, all the air needles are extended, which can ensure that the roller surface has good air permeability before adjustment, reduce biscuit adhesion, and improve the slitting effect.

[0013] Furthermore, the extension length and number of the ventilation needles can be adjusted by rotating the adjusting screw. One end of the adjusting screw is connected to the adjusting plate, and the other end extends out of the roller body and is equipped with a handwheel.

[0014] One end of the adjusting screw is connected to the adjusting disc, and the other end extends outside the roller body and is equipped with a handwheel. When the operator turns the handwheel on the adjusting screw, the adjusting disc rotates accordingly. The adjusting disc has annular grooves of different depths, into which the bottom of the vent needle is embedded. Due to the action of the spring mechanism, the vent needle automatically extends and retracts according to the depth of the groove. When the adjusting disc rotates to different positions, the vent needle extends or retracts according to the corresponding groove depth, thereby changing the extension length and number of vent needles. For example, when the adjusting disc rotates to a certain position, causing the bottom of the vent needle to enter a shallower groove, the vent needle will extend a shorter length under the action of the spring; while when the adjusting disc rotates to another position, causing the bottom of the vent needle to enter a deeper groove, the vent needle will retract more, or even completely retract into the roller body.

[0015] Furthermore, the inner roller cutting edge is square, and the outer roller cutting groove can be adjusted to form square or rectangular cutting areas with different side lengths.

[0016] The adjusting ring of the outer roller has multiple axially distributed slitting grooves, the shape and size of which can be designed as needed. The slitting blade of the inner roller has a basic square structure, and its shape and size are fixed. By rotating the adjusting nut, the outer roller moves axially, causing a relative displacement between the slitting grooves on the adjusting ring and the blade of the inner roller in the axial direction. Due to the fit between the slitting grooves and the blade, when the outer roller moves to different positions, the overlapping part of the slitting groove and the blade will form square or rectangular slitting areas with different side lengths. For example, when the outer roller moves to a certain position, the overlapping part of the slitting groove and the blade forms a square slitting area with side length 'a'; when the outer roller moves to another position, the overlapping part forms a rectangular slitting area with side length 'b'. In this way, the slitting shape and size can be flexibly adjusted according to the specifications of different biscuits.

[0017] Furthermore, the groove depth of the adjustment disc varies to accommodate vent needles with different extension lengths.

[0018] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the groove design of different depths allows the ventilation needles to extend to different lengths as needed, further optimizing the ventilation effect and reducing biscuit adhesion.

[0019] Furthermore, the vent roller and the slitting and forming roller are arranged sequentially along the biscuit conveying direction.

[0020] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the sequential setting of the ventilation hole roller and the slitting and forming roller ensures that the biscuits are slitting and forming immediately after the ventilation treatment, thereby improving production efficiency and product quality.

[0021] Furthermore, both the adjusting screw and the adjusting nut are located outside the roller assembly for easy operation. The adjusting nut is installed at the end of the outer roller and connected to the outer roller by a thread. The adjusting nut has a handle on its exterior for easy operation.

[0022] Both the adjusting screw and the adjusting nut are located externally on the roller assembly for easy operator adjustment. Specifically, one end of the adjusting screw passes through the end of the roller body and connects to the internal adjusting disc; the other end extends outside the roller body and is equipped with a handwheel for easy operation. The adjusting nut is installed at the end of the outer roller and is connected to the outer roller via threads. The adjusting nut has an easy-to-operate handle on its exterior, allowing the operator to adjust the position of the outer roller by turning the handle. This design allows the operator to easily adjust the extension length and number of the vent needles and the position of the slitting grooves without disassembling the roller assembly, improving the ease of use and flexibility of the device.

[0023] Furthermore, the spring mechanism is a compression spring, with one end connected to the vent needle and the other end connected to the adjustment disc.

[0024] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the design of the compression spring can ensure that the vent needle maintains a stable elastic force during the adjustment process, thereby improving the extensibility and reliability of the vent needle.

[0025] Furthermore, the adjusting ring of the outer roller is provided with scale markings to indicate the relative position of the cutting groove and the cutting edge of the inner roller.

[0026] The beneficial effects of adopting the above-mentioned improvement scheme are: the scale markings can help operators adjust the position of the slitting groove more accurately, thereby improving slitting accuracy and consistency.

[0027] Furthermore, the surfaces of both the vent roller and the slitting and forming roller are smoothed to reduce the adhesion of biscuits during the slitting and forming process.

[0028] The specific processing method is as follows:

[0029] Surface polishing: The roller surface is polished using high-precision polishing equipment to achieve a surface roughness of Ra0.8 or less, ensuring a smooth and flat roller surface.

[0030] Coating treatment: A food-grade non-stick coating is applied to the polished roller surface. This coating has excellent non-stick properties and high-temperature resistance, effectively preventing biscuits from sticking to the roller surface. The coating thickness is uniform, generally 0.1-0.3 mm.

[0031] Surface hardening treatment: The roller surface is hardened, such as by nitriding or carburizing, to improve the hardness and wear resistance of the roller surface and extend the service life of the roller.

[0032] Compared with existing technologies, the beneficial effects of the biscuit slitting and forming roller device provided by this utility model are as follows: Firstly, the ventilator needle design of the ventilator roller effectively reduces the adhesion between the biscuit and the roller surface, preventing the biscuit surface from being stretched and deformed during slitting, thus improving the appearance quality of the biscuits. Through the micro-airflow formed by the ventilator needles, the biscuit maintains good air permeability as it passes through the roller, reducing adhesion. Secondly, the inner and outer rollers of the slitting and forming roller are designed to flexibly adjust the slitting shape and size, adapting to the production needs of biscuits of different specifications and shapes. By rotating the adjusting nut, the outer roller moves axially, changing the relative position of the slitting groove and the inner roller cutting edge, thereby achieving fine-tuning of the slitting shape and size. Furthermore, by reducing adhesion and allowing for flexible adjustment, the device eliminates the need for frequent shutdowns for cleaning and adjustment during production, significantly improving production efficiency. The ventilator roller design reduces biscuit adhesion, while the flexible adjustment function of the slitting and forming roller reduces downtime due to mold changes. Meanwhile, the device can simultaneously meet the production needs of various biscuits, reducing equipment investment and lowering production costs. The combined design of the vented roller and the slitting and forming roller allows the device to not only complete slitting and forming operations, but also to be flexibly adjusted as needed to meet different production requirements.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0041] like Figure 1 , Figure 2 The diagram shown is an example of a biscuit cutting and forming roller device provided by this utility model. It includes a roller, which is fixed by a frame 30. A conveyor shaft 40 is provided at the bottom of the roller, and a rolling shaft 50 is provided at the bottom of the conveyor shaft 40. The rolling shaft 50 drives the conveyor shaft 40 to rotate, thereby causing the roller to rotate. The roller includes:

[0042] like Figure 3 As shown, the vent roller 10 includes a hollow roller body 11, multiple retractable vent needles 12, a spring mechanism 13, an adjusting plate 14, and an adjusting screw 15. The vent needles 12 are connected to the adjusting plate 14 inside the roller body 11 through the spring mechanism 13. The adjusting plate 14 can be rotated by the external adjusting screw 15. The adjusting plate 14 is provided with grooves of different depths. The bottom of the vent needles 12 is located in the grooves. As the adjusting plate 14 rotates, the vent needles 12 extend or retract from the surface of the roller body 11 under the action of the spring.

[0043] like Figure 4 As shown, the slitting and forming roller 20 includes two nested rollers, an inner roller 21 and an outer roller 22. The inner roller 21 has a basic slitting edge on its surface. The outer roller 22 is a rotatable adjusting ring with a slitting groove that mates with the cutting edge of the inner roller 21. The outer roller 22 is connected to an adjusting nut by a threaded connection. Rotating the adjusting nut allows the outer roller 22 to move axially, thereby changing the relative position of the slitting groove and the cutting edge of the inner roller 21.

[0044] During operation, the venting roller and the slitting and shaping roller allow the biscuits to pass through the venting roller for ventilation, reducing adhesion between the biscuits and the roller surface. They then proceed to the slitting and shaping roller for cutting and shaping. The two rollers work closely together during the biscuit processing to complete the cutting and shaping steps.

[0045] Usage steps:

[0046] The vent roller and the slitting and forming roller are installed in the rectangular frame respectively to ensure the stability and positional accuracy of the roller.

[0047] Install the transmission shaft and the rolling shaft into place, ensuring that the rolling shaft is connected to an external power source (such as a motor).

[0048] Depending on the thickness and shape of the biscuit, adjust the extension length and number of vent needles by rotating the adjusting screw. Initially, all vent needles are extended, but some can be retracted as needed.

[0049] According to the specifications of the biscuits, the position of the outer roller is adjusted by rotating the adjusting nut, which changes the relative position of the slitting groove and the inner roller cutting edge to form the required slitting shape and size.

[0050] Start the external power source to make the rolling shaft rotate, which in turn drives the ventilation hole roller and the slitting and forming roller to rotate through the transmission shaft.

[0051] The biscuit ingredients are fed into the device. The biscuits first pass through the ventilation roller and the ventilation needles reduce adhesion. Then they enter the slitting and shaping roller for slitting and shaping.

[0052] After being cut and shaped, the cookies are collected by conveyor belts or other collection devices, completing the production process.

[0053] In the above technical solution, the venting needles 12 extend fully out of the surface of the roller body in the initial state.

[0054] Furthermore, in the above technical solution, the extension length and number of the ventilation needles 12 can be adjusted by rotating the adjusting screw 15. One end of the adjusting screw 15 is connected to the adjusting plate 14, and the other end extends out of the roller body 11 and is equipped with a handwheel.

[0055] Furthermore, in the above technical solution, the inner roller 21 has a square cutting edge, and the outer roller 22 cutting groove can be adjusted to form square or rectangular cutting areas with different side lengths.

[0056] Furthermore, in the above technical solution, the groove depth of the adjusting plate 14 is different to accommodate the vent needles 12 with different extension lengths.

[0057] Furthermore, in the above technical solution, the vent roller 10 and the slitting and forming roller 20 are arranged sequentially along the biscuit conveying direction.

[0058] Furthermore, in the above technical solution, both the adjusting screw 15 and the adjusting nut are located outside the roller device for easy operation. The adjusting nut is installed at the end of the outer roller 22 and is connected to the outer roller 22 by threads. The outside of the adjusting nut is provided with a handle for easy operation.

[0059] Furthermore, in the above technical solution, the spring mechanism 13 is a compression spring, one end of which is connected to the vent needle 12 and the other end is connected to the adjustment plate 14.

[0060] Furthermore, in the above technical solution, the adjusting ring of the outer roller 22 is provided with a scale mark to indicate the relative position of the cutting groove and the cutting edge of the inner roller 21.

[0061] Furthermore, in the above technical solution, the surfaces of the vent roller 10 and the slitting and forming roller 20 are both smoothed to reduce the adhesion of biscuits during the slitting and forming process.

[0062] First embodiment:

[0063] The biscuit slitting and forming roller device in this embodiment includes a vent roller and a slitting and forming roller. The vent roller has a hollow design and multiple retractable vent needles installed inside. The vent needles are connected to an adjusting plate inside the roller via a spring mechanism, and the adjusting plate can be rotated via an external adjusting screw. The adjusting plate has grooves of different depths, and the bottom of the vent needles is located in the grooves. As the adjusting plate rotates, the vent needles extend or retract from the roller surface under the action of the spring. The slitting and forming roller consists of two nested rollers, an inner roller with a basic slitting edge on its surface, and an outer roller that is a rotatable adjusting ring with a slitting groove that mates with the inner roller's edge. The outer roller is connected to an adjusting nut via a threaded connection. Rotating the adjusting nut allows the outer roller to move axially, thereby changing the relative position of the slitting groove and the inner roller's edge.

[0064] In this embodiment, the number of holes per row for each cookie is 32323, meaning the first column has 3 ventilation holes, the second column has 2 ventilation holes, the third column has 3 ventilation holes, and so on. The relationship between the ventilation needles on the corresponding ventilation rollers is that the ratio of the number of holes between adjacent rows is 1.5:1. This distribution effectively reduces the adhesion between the cookie and the roller surface, while ensuring good air permeability during the cookie cutting process and reducing adhesion.

[0065] Second embodiment:

[0066] The biscuit slitting and forming roller device in this embodiment employs a nano-coating on the surface of the perforated roller. The coating thickness is 50-100 nm, exhibiting hydrophobic and oleophobic properties. This coating further reduces the adhesion between the biscuit and the roller surface, improving slitting quality. The slitting and forming roller utilizes a multi-stage adjustment structure, allowing for fine adjustment of the slitting grooves via multiple adjusting nuts. This design enables more complex slitting shapes and size adjustments, meeting higher precision production requirements.

[0067] This embodiment is suitable for production scenarios with high requirements for the quality and precision of cookie slicing, such as the production of high-end cookies or cookies with complex shapes. The porous roller with nano-coating treatment can effectively reduce adhesion, while the slicing and forming roller with a multi-level adjustment structure can achieve more precise slicing adjustments.

[0068] Specifically, the principle of this utility model is as follows: The biscuit slitting and forming roller device of this utility model solves the aforementioned problems of traditional devices through innovative structural design. The core of the device lies in two main components: the vented roller and the slitting and forming roller;

[0069] Ventilation roller: Featuring a hollow design with multiple retractable ventilation pins inside. These pins are connected to an internal adjusting disc via a spring mechanism, which can be rotated using an external adjusting screw. The adjusting disc has grooves of varying depths, with the bottom of the ventilation pins positioned within these grooves. As the adjusting disc rotates, the ventilation pins extend or retract from the roller surface under the action of the springs. This design creates a micro-airflow as the cookie passes through the roller, reducing adhesion between the cookie and the roller surface and preventing the cookie surface from being stretched and deformed during cutting.

[0070] The slitting and forming roller consists of two nested rollers, an inner and an outer one. The inner roller has a basic slitting edge on its surface, while the outer roller is a rotatable adjusting ring with a slitting groove that mates with the inner roller's cutting edge. The outer roller is connected to an adjusting nut via a threaded connection. Rotating the adjusting nut allows the outer roller to move axially, thereby changing the relative position of the slitting groove and the inner roller's cutting edge, enabling fine-tuning of the slitting shape and size. This design allows the device to flexibly adjust the slitting shape and size to meet the production needs of biscuits of different specifications.
