Description

Technical Field

[0001] This invention relates to the field of food production equipment technology, specifically a refrigerated cutting machine for producing milk crisps based on equidistant cutting. Background Technology

[0002] Milk crisp is a type of shortbread made primarily from butter, flour, sugar, milk powder, and egg liquid through mixing, baking, or drying. It is characterized by its loose texture, crisp taste, and high oil content. In the industrial production process of milk crisp, the large pieces of milk crisp dough after baking need to be cut into small, uniform pieces according to specifications for subsequent packaging and sales. Milk crisp cutting machines are automated equipment specifically designed to complete this equidistant cutting process. They typically consist of a conveying device, a cutting device, and a power system, and can cut continuous large-sized milk crisp dough into rectangular or square pieces that meet the requirements.

[0003] When existing dicing machines lift the blades to detach the material after dicing, the milk curd pieces easily adhere to the side of the blades due to surface adhesion and cannot fall off naturally. The milk curd pieces adhering to the blades are lifted by the blades, causing stringing or tearing between the diced milk curd pieces and the undiced parts. The cuts become uneven and the sizes are inconsistent, which seriously affects the appearance of the product. In addition, when the ambient temperature is high, the surface of the milk curd is easy to soften or even slightly melt, which also causes the softened milk curd to easily adhere to the side of the blades when the dicing blades rise.

[0004] Therefore, we propose a refrigerated cutting machine for the production of milk crisps based on equidistant cutting. Summary of the Invention

[0005] The purpose of this invention is to provide a refrigerated cutting machine for the production of milk crisps based on equidistant cutting, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a refrigerated cutting machine for producing milk crisp based on equidistant slicing, comprising a base plate, a U-shaped mounting plate, and a fixing cover. The U-shaped mounting plate and the fixing cover are both fixedly connected to the upper end of the base plate. The U-shaped mounting plate is located inside the fixing cover. A belt conveyor assembly is installed on the inner wall of the U-shaped mounting plate. A cutting assembly for slicing is installed on the fixing cover. A cooling assembly for cooling the milk crisp is installed on the fixing cover.

[0007] Preferably, the dicing assembly includes an electric push rod, which is fixedly connected to the upper end of the fixed cover. The output end of the electric push rod slides through the fixed cover. A lifting plate is fixedly connected to the output end of the electric push rod. Multiple guide rails are fixedly connected to the lower end of the lifting plate. A moving plate is slidably connected to the lower end of the multiple guide rails. A cross-cutting blade is fixedly connected to the lower end of the moving plate. Multiple vertical cutting blades arranged in an array are fixedly connected to one side of the cross-cutting blade near the lower part.

[0008] Preferably, guide grooves are provided on the inner walls of both sides of the fixed cover, the two guide grooves are symmetrically arranged and inclined, and guide blocks are fixedly connected to both sides of the movable plate, and the two guide blocks are slidably connected in the two guide grooves respectively.

[0009] Preferably, a plurality of arrayed guide cylinders are fixedly connected to one side of the movable plate, and a lifting rod is slidably connected inside each of the plurality of guide cylinders. A scraper is fixedly connected to the lower end of the plurality of lifting rods. The scraper is attached to the side of the horizontal cutting blade away from the vertical cutting blade. A one-way screw is rotatably connected to the top inner wall of the middle guide cylinder, and the lifting rod inside the middle guide cylinder is threaded onto the outside of the one-way screw.

[0010] Preferably, a small spur gear is rotatably connected to the upper end of the guide cylinder located in the middle. The output end of the small spur gear rotatably passes through the guide cylinder, and the output end of the small spur gear is fixedly connected to the upper end of the one-way screw. A gear set is provided on the upper end of the moving plate. One gear on one side of the gear set meshes with the small spur gear. A rack is fixedly connected to the lower end of the lifting plate. The rack meshes with one gear on the other side of the gear set.

[0011] Preferably, the cooling component includes a refrigeration device for generating cold air and a plurality of air nozzles arranged in an array. The refrigeration device is fixedly connected to one side of the upper end of the substrate, and the plurality of air nozzles are fixedly connected to the inner top wall of the fixed cover. The air outlet of the refrigeration device is connected to an air supply network, and the air inlet of the plurality of air nozzles penetrates the fixed cover and is connected to the side wall of the air supply network.

[0012] Preferably, the upper end of the U-shaped mounting plate is fixedly connected to two symmetrically arranged pads, both of which are located below the cross-cutting blade.

[0013] Preferably, a baffle plate is fixedly connected to the lower part of the inner wall of the fixed cover, and the baffle plate has multiple openings, with the multiple vertical cutting blades located inside the multiple openings respectively.

[0014] Preferably, a control panel is fixedly connected to the upper end of the substrate.

[0015] Preferably, the scraper is made of a flexible material.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses an electric push rod in the cutting assembly to drive the lifting plate to descend, which in turn drives the horizontal and vertical cutting blades to simultaneously cut the milk crisp at equal intervals. When the lifting plate rises, the guide block and guide groove work together to move the moving plate laterally, which moves the cut milk crisp pieces a certain distance along the conveying direction, so that the cut pieces are naturally separated from the uncut parts and avoids sticking. At the same time, the gear set on the moving plate meshes with the rack when it moves laterally, and drives the one-way screw to rotate through the acceleration transmission. This causes the scraper to automatically descend when the horizontal cutting blade rises and scrape off the milk crisp attached to the side of the blade. When the blade descends to cut, the scraper automatically rises to avoid interfering with the cutting, ensuring the integrity of the cut pieces and the smoothness of the cut, thus improving the efficiency and yield of continuous production.

[0017] 2. Cold air is generated by the refrigeration equipment and blown evenly into the cutting area inside the fixed cover through multiple arrayed nozzles via the air supply network. This keeps the milk crisp at a low temperature throughout the cutting process, thereby inhibiting the milk crisp from softening and melting due to friction and increased ambient temperature. This significantly reduces the risk of adhesion between the milk crisp and the cutting and belt conveyor components, ensuring that the cut pieces are regular in shape and have a smooth surface. It also helps to maintain the texture properties of the milk crisp and facilitates smooth subsequent processing. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-7 As shown, the present invention provides a technical solution: a refrigerated cutting machine for producing milk crisp based on equidistant cutting, comprising a base plate 1, a U-shaped mounting plate 2, and a fixing cover 3. The U-shaped mounting plate 2 and the fixing cover 3 are both fixedly connected to the upper end of the base plate 1. The U-shaped mounting plate 2 is located inside the fixing cover 3. A belt conveyor assembly 4 is installed on the inner wall of the U-shaped mounting plate 2. A cutting assembly 5 for cutting is installed on the fixing cover 3. A cooling assembly 6 for cooling the milk crisp is installed on the fixing cover 3.

[0022] Furthermore, the base plate 1 serves as the supporting foundation for the entire equipment, providing a stable mounting platform for each component. The U-shaped mounting plate 2 is fixed to the upper end of the base plate 1 and located inside the fixing cover 3, providing a stable mounting space for the belt conveyor assembly 4. The fixing cover 3 is fixed to the upper end of the base plate 1 and covers the U-shaped mounting plate 2 inside it, playing a sealing and protective role, reducing the interference of the external environment on the cutting process. The belt conveyor assembly 4 is installed on the inner wall of the U-shaped mounting plate 2 and is used to continuously convey the milk crisp material to be cut, realizing automated assembly line operation and improving production efficiency. The cutting assembly 5 is installed on the fixing cover 3 and cuts the milk crisp on the belt conveyor assembly 4 at equal intervals through periodic lifting and lowering movements, ensuring that the cut pieces are of uniform size. The cooling assembly 6 is installed on the fixing cover 3 and continuously cools the milk crisp during the cutting process to prevent the milk crisp from softening and sticking due to temperature rise, ensuring neat cut surfaces and complete cut pieces.

[0023] The belt conveyor assembly 4 is existing technology. It uses a drive device to drive the drive roller to rotate. The friction between the drive roller and the conveyor belt drives the conveyor belt to run in a cycle. At the same time, the tensioning device gives the conveyor belt an appropriate tension to ensure that there is enough friction between it and the roller to prevent slippage. After the material falls onto the conveyor belt from the feed end, it moves with the material by relying on the friction of the conveyor belt, thereby realizing continuous conveying from the feeding point to the unloading point. This will not be elaborated further here.

[0024] In the preferred embodiment of this technical solution, please refer to Figures 1-4 As shown, the dicing assembly 5 includes an electric push rod 501, which is fixedly connected to the upper end of the fixed cover 3. The output end of the electric push rod 501 slides through the fixed cover 3. A lifting plate 502 is fixedly connected to the output end of the electric push rod 501. Multiple guide rails 503 are fixedly connected to the lower end of the lifting plate 502. A moving plate 504 is slidably connected to the lower end of the multiple guide rails 503. A cross-cutting blade 505 is fixedly connected to the lower end of the moving plate 504. Multiple vertical cutting blades 506 arranged in an array are fixedly connected to one side of the cross-cutting blade 505 near the bottom.

[0025] Furthermore, the electric push rod 501 drives the lifting plate 502 to move up and down through its telescopic movement, providing the linear driving force required for cutting. The lifting plate 502 rises and falls synchronously with the electric push rod 501, stably transmitting power to the lower components to ensure the consistency of the cutting stroke. The guide rail 503 is fixed at the lower end of the lifting plate 502 and plays a guiding and supporting role for the moving plate 504, allowing the moving plate 504 to slide smoothly along the set direction. The moving plate 504 can move laterally on the guide rail 503, adapting to different cutting positions during cutting and assisting the cutting blade to detach from the material. The cross-cutting blade 505 descends with the moving plate 504 to complete the transverse cutting, ensuring that the length of the milk crisp is consistent. The vertical cutting blade 506 is fixedly connected to the lower side of the cross-cutting blade 505 and is distributed in an array. It descends synchronously with the cross-cutting blade 505 to complete the longitudinal equidistant cutting, cutting the milk crisp into multiple small squares in one go.

[0026] In the preferred embodiment of this technical solution, please refer to Figure 3 and Figure 4 As shown, guide grooves 507 are provided on both inner walls of the fixed cover 3. The two guide grooves 507 are symmetrically arranged and inclined. Guide blocks 508 are fixedly connected to both sides of the movable plate 504. The two guide blocks 508 are slidably connected in the two guide grooves 507 respectively.

[0027] Furthermore, the guide grooves 507 are opened on the inner walls of both sides of the fixed cover 3 and are inclined. During the lifting and lowering of the moving plate 504, the guide blocks 508 are forced to slide along its inclined trajectory, thereby causing the moving plate 504 to generate lateral displacement when moving up and down. This helps the blade to automatically detach from the cut milk crisps when it is lifted and reduces adhesion. The guide blocks 508 are fixedly connected to both sides of the moving plate 504 and slidably connected in the two guide grooves 507 respectively. The inclined constraint of the guide grooves 507 is transmitted to the moving plate 504, ensuring that the moving plate 504 moves smoothly along the predetermined inclined trajectory. This allows the cutting assembly 5 to gently push the milk crisps in the conveying direction after cutting, preventing the cut pieces from re-adhering to the uncut parts.

[0028] In the preferred embodiment of this technical solution, please refer to Figure 5 and Figure 6 As shown, a plurality of arrayed guide cylinders 509 are fixedly connected to one side of the movable plate 504. Lifting rods 510 are slidably connected inside each of the guide cylinders 509. A scraper 511 is fixedly connected to the lower end of the multiple lifting rods 510. The scraper 511 is attached to the side of the cross-cutting blade 505 away from the vertical cutting blade 506. A one-way screw 512 is rotatably connected to the top inner wall of the guide cylinder 509 located in the middle. The lifting rod 510 inside the guide cylinder 509 located in the middle is threaded onto the outside of the one-way screw 512. A small spur gear 513 is rotatably connected to the upper end of the guide cylinder 509 located in the middle. The output end of the small spur gear 513 rotatably passes through the guide cylinder 509, and the output end of the small spur gear 513 is fixedly connected to the upper end of the one-way screw 512. A gear set 514 is provided on the upper end of the moving plate 504. One gear on one side of the gear set 514 meshes with the small spur gear 513. A rack 515 is fixedly connected to the lower end of the lifting plate 502. The rack 515 meshes with one gear on the other side of the gear set 514.

[0029] Furthermore, the guide cylinder 509 is fixed to one side of the moving plate 504, providing a vertical guide channel for the lifting rod 510, enabling the scraper 511 to move stably up and down along the side of the cross-cutting blade 505, avoiding deviation. The lifting rod 510 is slidably connected inside the guide cylinder 509 and its lower end is connected to the scraper 511, transmitting the constraint of the guide cylinder 509 to the scraper 511, ensuring that the scraper 511 always moves in contact with the surface of the cross-cutting blade 505 without deviation. The scraper 511 is attached to the side of the cross-cutting blade 505 away from the vertical cutting blade 506, and slides along the side of the cross-cutting blade 505 under the action of the lifting rod 510, pushing down the milk powder adhering to the surface of the cross-cutting blade 505 in time and keeping the blade clean. The one-way screw 512 is rotatably connected to the inner wall of the top of the guide cylinder 509 located in the middle and threadedly engaged with the corresponding lifting rod 510. It drives the lifting rod 510 to move up and down through its own forward and reverse rotation, so that... The scraper 511 only descends to scrape material when the blade rises and automatically retracts when the blade descends to avoid interference with cutting. The small spur gear 513 is rotatably connected to the upper end of the guide cylinder 509 located in the middle, and its output end is fixedly connected to the upper end of the one-way screw 512. It receives the rotational power of the gear set 514 and transmits it unidirectionally to the one-way screw 512, ensuring that the action timing of the scraper 511 is synchronized with the cutting cycle. The gear set 514 is set on the upper end of the moving plate 504, and one side of the gear meshes with the small spur gear 513. It accelerates the power of the moving plate 504 when it moves laterally and then transmits it to the small spur gear 513, so that the scraper 511 can obtain a fast-response driving force. The rack 515 is fixedly connected to the lower end of the lifting plate 502 and meshes with the gear on the other side of the gear set 514. The lifting motion of the lifting plate 502 drives the gear set 514 to rotate, so that the automatic reciprocating action of the scraper 511 can be realized without an additional power source.

[0030] In the preferred embodiment of this technical solution, please refer to Figure 1 and Figure 7 As shown, the cooling component 6 includes a refrigeration device 601 for generating cold air and a plurality of air jets 602 arranged in an array. The refrigeration device 601 is fixedly connected to one side of the upper end of the substrate 1. The plurality of air jets 602 are all fixedly connected to the inner wall of the top of the fixed cover 3. The air outlet of the refrigeration device 601 is connected to the air supply network 603. The air inlet of the plurality of air jets 602 all penetrates the fixed cover 3. The air inlet of the plurality of air jets 602 is all connected to the side wall of the air supply network 603.

[0031] Furthermore, the refrigeration device 601 is fixedly connected to one side of the upper end of the substrate 1. It generates low-temperature cold air through internal refrigeration circulation to provide a continuous cold source for the cutting area, which can effectively reduce the temperature of the milk crisp and prevent it from softening and sticking. The air supply network 603 is connected to the air outlet of the refrigeration device 601 and distributes the generated cold air to each jet nozzle 602 to ensure that the cold air is evenly distributed to different positions inside the fixed cover 3 and avoid uneven local cooling. The jet nozzles 602 are fixedly connected to the top inner wall of the fixed cover 3 and are distributed in an array. Their air inlets penetrate the fixed cover 3 and connect to the side wall of the air supply network 603, spraying the cold air evenly to the cutting area below in the form of multiple airflows, so that the surface of the milk crisp and the area around the blade are fully cooled and the milk crisp is kept at a low temperature during the cutting process.

[0032] Refrigeration equipment 601 is existing technology, employing a compression refrigeration system. It mainly consists of four core components: a compressor, a condenser, an expansion valve, and an evaporator, connected sequentially through pipelines to form a closed-loop circuit. The compressor draws in low-temperature, low-pressure gaseous refrigerant from the evaporator and compresses it into a high-temperature, high-pressure gas. This gas is then discharged into the condenser, where it dissipates heat to the outside environment via air or water cooling, causing the refrigerant to condense into a high-pressure, room-temperature liquid. The high-pressure liquid refrigerant then passes through the expansion valve for throttling and pressure reduction, becoming low-temperature, low-pressure wet vapor that enters the evaporator. Inside the evaporator, it absorbs heat from the surrounding environment and boils and vaporizes, thus achieving a cooling effect. The vaporized low-temperature, low-pressure gaseous refrigerant is then drawn back into the compressor, and this cycle repeats continuously, producing cool air for subsequent use. Further details are omitted here.

[0033] In the preferred embodiment of this technical solution, please refer to Figure 3 As shown, two symmetrically arranged pads 7 are fixedly connected to the upper end of the U-shaped mounting plate 2, and both pads 7 are located below the cross-cutting blade 505.

[0034] Furthermore, the pad 7 is fixedly connected to the upper end of the U-shaped mounting plate 2 and the two are symmetrically arranged. Both pads 7 are located below the cross-cutting blade 505, providing a hard support plane for it when the cross-cutting blade 505 descends to cut, preventing the blade from directly hitting the U-shaped mounting plate 2 and causing damage to the blade edge, while ensuring that the bottom is evenly stressed during cutting so that the cut is complete.

[0035] In the preferred embodiment of this technical solution, please refer to Figure 6 As shown, a baffle plate 8 is fixedly connected to the lower part of the inner wall of the fixed cover 3. The baffle plate 8 has multiple openings 9, and multiple vertical cutting blades 506 are located inside the multiple openings 9 respectively.

[0036] Furthermore, the baffle plate 8 is fixedly connected to the lower part of the inner wall of the fixed cover 3. During the cutting process, it plays a role in limiting and blocking the milk crisp pieces, preventing the milk crisp pieces from shifting excessively with the blades when being moved laterally, and ensuring accurate cutting position. The openings 9 are opened on the baffle plate 8 and the number corresponds to the vertical cutting blades 506. Multiple vertical cutting blades 506 are located inside multiple openings 9, providing a through channel for the vertical cutting blades 506, so that the blades can pass smoothly through the baffle plate 8 to complete the cutting action, while avoiding interference and collision between the blades and the baffle plate 8.

[0037] In the preferred embodiment of this technical solution, please refer to Figure 1 and Figure 6 As shown, a control panel 10 is fixedly connected to the upper end of the substrate 1, and the scraper 511 is made of flexible material.

[0038] Furthermore, the control panel 10 is fixedly connected to the upper end of the substrate 1. The control panel 10 is existing technology and consists of a microprocessor, a human-machine interface, a signal input / output interface, a power module, and corresponding control circuits. The operator inputs start, stop, speed adjustment, and other commands through the human-machine interface. After receiving the commands, the microprocessor or PLC processes them according to the internal preset control program and sends corresponding control signals to each execution component of the equipment through the signal output interface, thereby realizing centralized monitoring and automatic adjustment of the entire cutting machine's operating status, cutting rhythm, and cooling effect. This will not be elaborated further here. The scraper 511 is made of flexible material and can adapt to the slight unevenness of the blade surface when sliding up and down against the side of the cross-cutting blade 505, ensuring that the effect of scraping off the sticky milk crisp is thorough while avoiding scratching the blade surface.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
