Description

Technical Field

[0001] This utility model relates to the field of soybean product production technology, especially tofu, and specifically to an automatic tofu-slicing machine for tofu production lines. Background Technology

[0002] Baojiang tofu is a local specialty snack. Its production process is similar to that of regular tofu, except for an additional step of soaking in baking soda water. Essentially, after the tofu, made with gypsum, is sliced, it is soaked in water with baking soda for a period of time, then rinsed and dried. This process creates a creamy inner layer, making it popular with consumers.

[0003] The production of tofu with a crispy skin requires slicing. In factory production, slicing is usually done by specialized equipment. The main drawback of current equipment is that it is difficult for the blade to completely overlap with the bottom of the tray when cutting. To avoid blade obstruction caused by the blade extending below the surface of the tray, a certain space is usually left between the blade tip and the tofu tray. However, this space prevents the tofu from being completely cut, and there will be some entanglement when removing it from the tray, resulting in some defects in the sliced ​​tofu. When the blade tip is below the surface of the tray, the blade tip will cut into the tray, which can cause difficulty in cutting or even break the blade tip. Summary of the Invention

[0004] This utility model is an automatic tofu cutting machine for tofu production line. It adopts a movable blade structure, which allows the blade to rotate when it comes into contact with the tray, changing the cutting angle of the blade and avoiding blade damage caused by hard contact between the blade and the tray. At the same time, the tilt of the blade allows it to fully contact the surface of the tray, so as to completely cut the tofu and ensure product quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The automatic tofu cutting machine for tofu production line includes a frame and a reciprocating belt mounted on the frame. The reciprocating belt is driven by a stepper motor, and a movable tray is installed on the upper part of the reciprocating belt. A longitudinal gantry and a transverse gantry are respectively located on the right side of the frame, and a cutting knife assembly is installed in each of the longitudinal and transverse gantry. Two longitudinally arranged slide rails are provided on the frame to the right of the longitudinal gantry, and the transverse gantry moves longitudinally reciprocating on the slide rails.

[0007] The horizontal gantry is an inverted U-shaped structure. The bottom of both sides of the horizontal gantry is equipped with sliding clips corresponding to the slide rails. By sliding the sliding clips on the slide rails, the horizontal gantry slides back and forth on the slide rails. The slide rails are also equipped with telescopic rods that drive the horizontal gantry.

[0008] Both the longitudinal and transverse gantry frames are equipped with U-shaped brackets, with the bracket openings facing downwards. The tops of the brackets are connected to the tops of the corresponding gantry frames via telescopic rods. The bottoms of the brackets are equipped with rotating parts, and the cutter assembly is mounted on the rotating parts.

[0009] The rotating part includes a rotating shaft and a sleeve mounted on the rotating shaft. The rotating shaft is located at the bottom of the bracket, and the sleeve is located on the outside of the rotating shaft. A torsion spring is provided between the rotating shaft and the sleeve, and the cutter assembly is located on the side of the sleeve.

[0010] The cutting blade assembly corresponding to the longitudinal gantry is located on the left side of the corresponding sleeve, while the cutting blade assembly corresponding to the transverse gantry is located at the front of the corresponding sleeve.

[0011] The cutting blade assembly includes several cutting blades and corresponding cutting blade seats. The side of the sleeve is provided with a sliding groove corresponding to the cutting blade seat. The cutting blade seat is installed in the sliding groove, and the cutting blade is installed vertically on the cutting blade seat.

[0012] Furthermore, the slide groove has a T-shaped structure, and the cutter holder has a corresponding T-shaped structure, with the cutter holder slidably installed within the slide groove.

[0013] Furthermore, a clamping plate is provided on both sides of the cutter holder. The middle part of the clamping plate is hinged to both sides of the cutter holder. The distance from the hinge point between the clamping plate and the cutter holder to the bottom of the clamping plate is greater than the distance from the hinge point to the bottom of the slide groove. A support spring is provided on the inner side of the top of the clamping plate to support the top outward. The support spring supports the top of the clamping plate so that the bottom of the clamping plate is close to the bottom of the slide groove and supports and rubs against the bottom of the slide groove.

[0014] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0015] This device features a rotatable cutter structure. When cutting tofu on a tray, the bottom of the cutter can be extended downwards below the upper surface of the tray. The cutter rotates as it passes over the tray, preventing damage to the blade from hard contact. At the same time, the cutter tilts and fits against the surface of the tray, completely cutting the tofu and ensuring the quality of the tofu slices. Attached Figure Description

[0021] like Figures 1-4 The tofu production line shown includes an automatic tofu cutting machine, which includes a frame 1 and a reciprocating belt 2 mounted on the frame 1. The reciprocating belt 2 is driven by a stepper motor 201, and a movable tray 202 is mounted on the upper part of the reciprocating belt 2. A longitudinal gantry 301 and a transverse gantry 302 are respectively provided on the right side of the frame 1. Cutting knife groups 4 are respectively provided in the longitudinal gantry 301 and the transverse gantry 302. Two longitudinally arranged slide rails 303 are provided on the frame 1 to the right of the longitudinal gantry 301, and the transverse gantry 302 moves longitudinally and reciprocally on the slide rails 303.

[0022] The transverse gantry 302 has an inverted U-shaped structure. The bottom of both sides of the transverse gantry 302 is provided with sliding clips 304 corresponding to the slide rail 303. By sliding the sliding clips 304 on the slide rail 303, the transverse gantry 302 slides back and forth on the slide rail 303. The slide rail 303 is also provided with a telescopic rod 305 for driving the transverse gantry 302.

[0023] Both the longitudinal gantry 301 and the transverse gantry 302 are equipped with U-shaped brackets 306, with the openings of the brackets 306 facing downwards. The tops of the brackets 306 are connected to the tops of the corresponding gantry via telescopic rods 307. The bottoms of the brackets 306 are equipped with rotating parts 5, and the cutter assembly 4 is mounted on the rotating parts 5.

[0024] The rotating part 5 includes a rotating shaft 501 and a sleeve 502 disposed on the rotating shaft 501. The rotating shaft 501 is disposed at the bottom of the bracket 306, and the sleeve 502 is disposed on the outside of the rotating shaft 501. A torsion spring 503 is disposed between the rotating shaft 501 and the sleeve 502. The cutter assembly 4 is disposed on the side of the sleeve 502.

[0025] The cutting blade group 4 corresponding to the longitudinal gantry 301 is located on the left side of the corresponding sleeve 502, and the cutting blade group 4 corresponding to the transverse gantry 302 is located at the front of the corresponding sleeve 502.

[0026] The cutter assembly 4 includes several cutters 401 and corresponding cutter seats 402. The side of the sleeve 502 is provided with a sliding groove 504 corresponding to the cutter seat 402. The cutter seat 402 is installed in the sliding groove 504, and the cutters 401 are installed vertically on the cutter seat 402.

[0027] Furthermore, the slide groove 504 has a T-shaped structure, and the cutter holder 402 has a corresponding T-shaped structure, with the cutter holder 402 slidably installed within the slide groove 504.

[0028] Furthermore, the cutter holder 402 is provided with a clamping plate 403 on both sides. The middle part of the clamping plate 403 is hinged to both sides of the cutter holder 402. The distance from the hinge point between the clamping plate 403 and the cutter holder 402 to the bottom of the clamping plate 403 is greater than the distance from the hinge point to the bottom of the slide groove 504. The inner side of the top of the clamping plate 403 is provided with a support spring 404 to support the top of the clamping plate 403 outward. The support spring 404 supports the top of the clamping plate 403 so that the bottom of the clamping plate 403 is close to the bottom of the slide groove 504 and supports and rubs the bottom of the slide groove 504.

[0029] During operation, tofu is placed on a tray and then, driven by a reciprocating belt, first enters the area corresponding to the horizontal gantry. At this point, the vertical telescopic rod pushes the bracket downwards until the tip of the blade is below the surface of the tray. Before the blade contacts the tray, the longitudinal telescopic rod pushes the horizontal gantry backwards. As the blade passes the tray, the tray supports the blade, causing the blade and sleeve to tilt. The tilted blade then cuts the tofu along the surface of the tray. When the blade leaves the tray surface, the sleeve, driven by a torsion spring, returns the cutter assembly to the vertical position. The vertical telescopic rod then lifts the bracket, rotating part, and cutter assembly upwards, completing the longitudinal cut. Subsequently, the reciprocating belt carries the longitudinally cut tofu through the longitudinal gantry and the internal cutter assembly for transverse cutting. The overall working process of the rotating part and cutter assembly is the same as above, except that the bracket, rotating part, and cutter assembly do not move; transverse cutting is achieved by the movement of the tray.

[0030] The device cuts tofu using a tiltable and rotating blade. The tilting of the blade avoids hard damage from contact with the tray, and the tilted blade can fully contact the tray, allowing for better cutting of the tofu and resulting in a better-looking finished product.
