Description

Technical Field

[0001] This invention relates to the field of French fry cutting technology, and more particularly to a French fry cutting device. Background Technology

[0002] French fries are a common fast food made by deep-frying potatoes cut into strips. To improve processing efficiency and uniformity of thickness, automated French fry cutting devices are typically used to cut potatoes in batches.

[0003] Patent publication number CN100336474C discloses a potato cutting machine, which includes a water inlet pipe and a material conveying pipe at the inlet and outlet ends of a pressure pump. The water inlet pipe is connected to a water storage tank, and a cutting device is installed on the material conveying pipe. A sealed feeding device is connected in parallel to the material conveying pipe between the pressure pump and the cutting device. The device consists of a frame and a rotatable star-shaped feeding wheel, with a star wheel container and a sealed container arranged circumferentially on the star-shaped feeding wheel. This equipment features high yield and production efficiency, low power consumption, and convenient operation.

[0004] In the above technical solution, in order to cut potato materials, a pressure pump and a sealed feeding device are set at one end of the conveying pipe, and a combined cutting device is set at the other end. High-pressure water flow is used to drive the potato materials through the combined cutting device, and the combined cutting device cuts them into French fries. However, in order to avoid potatoes getting stuck in the conveying pipe during the conveying process, the inner diameter of the conveying pipe usually needs to be set to 1.2-1.8 times the outer diameter of the potato materials. During the conveying process, the potato materials are affected by gravity and will be located in the lower middle position of the conveying pipe, and collide with the lower middle position of the combined cutting device, causing the combined cutting device to be prone to skew and damage. Summary of the Invention

[0048] The technical solutions of this invention will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0049] like Figure 1-11 As shown, a French fry cutting device of the present invention includes a conveying pipe 1, a cutting blade 2, and a lifting part 3.

[0050] Among them, the conveying pipeline 1 is used to convey high-pressure water and potatoes.

[0051] The slicing blade 2 is used to cut potatoes into French fries inside the conveying pipe 1. The slicing blade 2 is fixedly installed inside the conveying pipe 1.

[0052] The lifting part 3 is used to change the direction of potato movement. The lifting part 3 is set on the conveying pipe 1. When the potato in the conveying pipe 1 passes through the lifting part 3, the lifting part 3 abuts against the potato in the conveying pipe 1. Preferably, it abuts and guides the bottom side of the potato, so that it moves in the conveying direction of the conveying pipe 1 and moves a certain distance in the vertical upward direction. This is so that the potato is located at the center position of the cutting blade 2 when it passes through the cutting blade 2, thereby avoiding the problem of the cutting blade 2 being deflected and damaged due to the potato being conveyed in the middle and lower part of the conveying pipe 1, and ensuring the service life of this French fry cutting device. There are two, including but not limited to two, situations in which the lifting part 3 drives the potato to lift and make the potato contact the center position of the cutting blade 2. The first situation is... In one scenario, the potato is continuously lifted and moved between the lifting part 3 and the cutting blade 2. When the potato reaches the position of the cutting blade 2, it is exactly at its center. In another scenario, the potato is first lifted and moved between the lifting part 3 and the cutting blade 2, and then lowered due to gravity. When the potato reaches the position of the cutting blade 2, it is exactly at its center. Both scenarios meet the design purpose of this invention. Of course, the potatoes transported by the conveying pipe 1 cannot be completely uniform. Therefore, the landing point of the potatoes on the cutting blade 2 will have some differences. The lifting part 3 is designed not to ensure that every potato passes through the center position of the cutting blade 2, but to ensure that most potatoes pass through the center position of the cutting blade 2 during the transport process.

[0053] French fry length is an important indicator in French fry processing. Given the same volume, oblong potatoes can produce longer French fry than spherical potatoes. Therefore, this French fry cutting device preferably uses oblong potatoes; that is, the potatoes transported in conveying pipe 1 are oblong potatoes. The length of the oblong potato is X, and the width is Y. Before the potatoes enter the French fry cutting device, they are first screened using the two data points X and Y. Correspondingly, let the inner diameter of the cavity of the pipe conveying the oblong potatoes be Z. The inner diameter of the cavity of the pipe located at the top part 3 is... The diameter is Z1, and the inner diameter of the pipe cavity not located at the top part 3 is Z2. Let Z2>X>Z1>Y, that is, potatoes can be transported in any shape in the pipe cavity without the top part 3. However, when the potatoes are transported to the position of the top part 3, due to the relatively small inner diameter of its cavity, the potatoes need to be rotated so that the two tips are facing the transport direction of the transport pipe 1 in order to pass through the transport pipe 1. Even if the tips of the potatoes collide with the cutting blade 2 to cut them, the length of the processed French fries is guaranteed to be the longest that can be processed, thus meeting the processing requirements.

[0054] The average size of potatoes varies from batch to batch. Using the same conveying pipe 1, cutting blade 2 and lifting part 3 will result in differences in the contact point between the potato and the cutting blade 2. In order to improve the adaptability of this French fry cutting device, the lifting part 3 can be moved along the conveying direction of the conveying pipe 1 to adjust its distance from the cutting blade 2.

[0055] For the form of the lifting part 3, the present invention provides two specific structures:

[0056] The first specific structure is as follows: Figure 2 As shown, the lifting part 3 is a fixed wedge 31, which is fixedly installed on the bottom side inside the conveying pipe 1. The distance from the side of the fixed wedge 31 close to the center line of the conveying pipe 1 to the center line of the conveying pipe 1 gradually decreases along the conveying direction of the conveying pipe 1. Even though the bottom side of the fixed wedge 31 is fixed to the bottom side inside the conveying pipe 1, the top side of the fixed wedge 31 is inclined. When the potato is conveyed in the conveying pipe 1 and comes into contact with the fixed wedge 31, the fixed wedge 31 applies an upward force to the potato, so that the potato can be lifted a distance inside the conveying pipe 1 so that the potato is located in the center position when it passes the cutting blade 2.

[0057] Preferably, the distance from the side of the fixed wedge 31 closest to the centerline of the conveying pipe 1 to the centerline of the conveying pipe 1 changes at a rate that first gradually decreases, then gradually increases, and finally gradually decreases to zero. Figure 2 As shown, if the conveying direction of the conveying pipe 1 is taken as the abscissa, and the top side of the fixed wedge 31 is regarded as a curve, the slope of the tangent of this curve gradually decreases first, then gradually increases, and finally gradually decreases to zero. At this time, the top surface of the fixed wedge 31 can be regarded as two steep slopes. The two steep slopes lift the potato in segments so that the potato is lifted more slowly and stably. At the same time, the two steep slopes can have different functions, such as one steep slope can rotate the potato so that the tip of the potato is facing the cutting blade 2, while the other steep slope can lift the potato.

[0058] like Figure 3 As shown, in order to prevent the potatoes from shaking in a direction that is perpendicular to the conveying direction of the conveying pipe 1 and parallel to the horizontal plane, a limiting groove 301 can be opened on the top side of the fixed wedge 31 near the cutting tool 2. The cross-section of the limiting groove 301 is arc-shaped and is used to limit the potatoes.

[0059] The first specific structure of the aforementioned lifting part 3 has the effect of simple structure and can reduce investment costs. However, since the lifting part 3 is set inside the conveying pipe 1, its adaptive adjustment function is relatively poor.

[0060] The second specific structure is as follows: Figure 4As shown, the conveying pipe 1 includes a first pipe 11 and a second pipe 12, and the lifting part 3 includes two reducing connecting pipes 32 and a lifting pipe 33. The cutting tool 2 is fixedly installed inside the first pipe 11; the second pipe 12 is coaxial with and spaced apart from the first pipe 11; the two reducing connecting pipes 32 are respectively sealed and fixed at one end of the first pipe 11 near the second pipe 12 and at one end of the second pipe 12 near the first pipe 11, and are connected to them; the lifting pipe 33 is fixedly installed between the two reducing connecting pipes 32. The inner wall of the lifting tube 33 is continuously connected to the inner wall of the variable diameter connecting tube 32. The inner diameter of the lifting tube 33 is smaller than the inner diameter of the variable diameter connecting tube 32, and the top side inside the lifting tube 33 is flush with the top side inside the variable diameter connecting tube 32. The lifting part 3 is designed independently and is connected and fixed between the first pipe 11 and the second pipe 12. When the potato enters the lifting part 3, it is first guided and lifted by the inclined bottom surface of the variable diameter connecting tube 32, and then passes through the lifting tube 33 and the first pipe 11 in sequence, and finally passes through the center position of the cutting knife 2.

[0061] like Figure 4 As shown, the variable diameter connecting pipe 32 connected to the first pipe 11 is sealed and fixed inside the first pipe 11 in a slidable manner; the variable diameter connecting pipe 32 connected to the second pipe 12 is sealed and fixed outside the second pipe 12 in a slidable manner; by sliding the two variable diameter connecting pipes 32 along the conveying direction of the conveying pipe 1, the lifting part 3 can be moved in the conveying direction of the conveying pipe 1.

[0062] Optionally, to allow the two reducing connecting pipes 32 to be slidably fixedly connected to the first pipe 11 and the second pipe 12 respectively, an adjusting mechanism 4 can also be provided. The adjusting mechanism 4 includes a connecting flange 41, multiple screws 42, and nuts 43, such as... Figure 7 As shown, connecting flanges 41 are fixedly installed on the first pipe 11, the second pipe 12, and the reducing connecting pipe 32, respectively. The connecting flanges 41 on the first pipe 11 and the second pipe 12 have multiple circular connecting holes 401, and the connecting flanges 41 on the reducing connecting pipe 32 have multiple arc-shaped connecting holes 402. The multiple circular connecting holes 401 and multiple arc-shaped connecting holes 402 are arranged in a circumferential array about the center line of the first pipe 11 and correspond one-to-one. The screw 42 passes through the corresponding circular connecting holes 401 and arc-shaped connecting holes 402. Each screw 42 is connected to multiple nuts 43 by threaded engagement. The nuts 43 abut against the side of the connecting flange 41 to fix the relative position of the multiple connecting flanges 41. By turning the nuts 43, the lifting part 3 can be moved along the conveying direction of the conveying pipe 1.

[0063] Since the top side inside the lifting tube 33 is flush with the top side inside the reducing connecting tube 32, and the inner diameter of the lifting tube 33 is smaller than the inner diameter of the reducing connecting tube 32, the side view projection of the reducing connecting tube 32 has an additional crescent-shaped area below the side view projection of the lifting tube 33. Furthermore, since the connecting flange 41 on the reducing connecting tube 32 has an arc-shaped connecting hole 402, the lifting part 3 can rotate, thereby changing the height of the center line of the lifting tube 33 to adjust the supporting force on the potato, which is suitable for potatoes of different specifications.

[0064] Optionally, a T-shaped pipe 5 can also be provided. The T-shaped pipe 5 is used to connect the potato conveying device and the high-pressure water conveying device to the conveying pipe 1. The T-shaped pipe 5 includes a first connector 501, a second connector 502 and a third connector 503 that are internally connected. The first connector 501 and the second connector 502 are coaxially arranged, and the first connector 501 is coaxially arranged and sealed with the end of the conveying pipe 1 away from the cutting blade 2. The second connector 502 is used to connect the high-pressure water flow device to deliver high-pressure water into the first connector 501. The third connector 503 is used to connect to the potato screening device to deliver potatoes into the first connector 501. The center line of the third connector 503 is perpendicular to the center line of the first connector 501.

[0065] To keep the potato centered within the conveying pipe 1, a spiral blade 6 can be installed. The spiral blade 6 is fixedly installed within the second connector 502. When water flows through the spiral blade 6, it forms a spiral water flow, which helps to keep the potato centered within the conveying pipe 1 and accelerates the water flow speed. At the same time, its rotation also causes the potato to rotate, allowing it to be conveyed with its tip facing the conveying direction of the conveying pipe 1. Correspondingly, the slicing blade 2 includes multiple blades 21 fixedly connected in a grid pattern. The end of the blade 21 in front of the conveying direction of the conveying pipe 1 is parallel to the conveying direction of the conveying pipe 1, and the end of the blade 21 behind the conveying direction of the conveying pipe 1 forms an angle of 30-60 degrees with the conveying direction of the conveying pipe 1. That is, the end of the blade 21 that receives the potato is inclined, and its inclination direction is consistent with the rotation direction of the potato. When the rotating potato collides and cuts with the inclined blade 21, it can avoid the potato being broken by the blade 21, but rather being cut by the blade 21, thus increasing the flatness of the French fries surface.

[0066] The working principle of the French fry cutting device of the present invention is as follows:

[0067] Connect the potato screening device to the third connector 503 and the high-pressure water input device to the second connector 502. The potatoes are transported into the conveying pipe 1 by the water flow and move along the conveying direction of the conveying pipe 1. When the potatoes pass the lifting part 3, they can be lifted by the lifting part 3, thereby being raised a certain distance in the conveying pipe 1. This allows the potatoes to collide with the center position of the cutting blade 2 during the lifting process or during the process of being lifted and then lowered, ensuring the service life of the cutting blade 2. At the same time, the position of the lifting part 3 can be adjusted according to the size of the potatoes, so that this French fry cutting device can be adapted to potatoes of different sizes.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
