Description

Technical Field

[0001] The present invention relates to the technical field of tofu cutting tools, and particularly to a Wensi tofu cutting device. Background Art

[0002] Wensi tofu originated in Yangzhou. It is a traditional special famous dish in Jiangsu Province and belongs to Huaiyang cuisine of Jiangsu cuisine. This dish has a long history. It has extremely strict ingredient selection, delicate knife skills, is soft, tender, clear and mellow, melts in the mouth, and at the same time has the effects of regulating malnutrition and tonifying deficiency and nourishing the body. This dish is also an excellent recipe for the elderly and children to choose when dining.

[0003] Wensi tofu and its production highly test the knife skills. It is very difficult to cut without certain skills. At present, there are molds for cutting Wensi tofu on the market. Generally, they are composed of a cylindrical body with both ends penetrated, a sieve mesh fixed at one end of the cylindrical body, and a pressing plate. A tofu block conforming to the cross-section of the cylindrical body is placed into the cylindrical body, and then the tofu block is pushed by the pressing plate to move towards one end of the sieve mesh, and is extruded into strips under the sieve holes of the sieve mesh. However, such devices have a common problem, that is, they can only form strips of tofu within a certain diameter range, or are called chrysanthemum tofu, and cannot reach the filamentous form of Wensi tofu. Moreover, this kind of mold can only act on egg tofu with a firmer texture and stronger cohesion, while for lactone tofu (traditional Wensi tofu is made of lactone tofu), when extruding, as Figure 1 shown, the pressure of the pressing plate on the tofu block is downward, and the frictional force of the inner wall of the cylindrical body on the edge of the tofu block is upward. Therefore, the tofu at the edge of the cylindrical body is very easy to be damaged. And when extruding, the pressure is mainly concentrated at the pressing plate, which also easily causes the tofu at the top to be damaged, that is, it cannot maintain a complete shape. And when extruding, because it is necessary to overcome the frictional force at the edge of the cylindrical body, a relatively large pressure needs to be applied, which further causes the tofu to be crushed and sprayed out instead of being extruded into filaments. For this reason, we propose a Wensi tofu cutting device. Summary of the Invention

[0004] The purpose of the present invention is to provide a Wensi tofu cutting device to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A Wensi tofu cutting device includes a hollow cylindrical body with both ends open. One end is the inlet for the tofu block, and the other end is the outlet. At least three conveyor belts are sleeved on the side wall of the cylindrical body through roller shafts. The conveying direction of the conveyor belts is towards both ends of the cylindrical body. The conveyor belts form the feeding of the tofu block and prevent the tofu block from contacting the inner wall of the cylindrical body. A sieve mesh is arranged at the outlet end of the cylindrical body. A pushing ring is sleeved on the outer wall of the cylindrical body. The pushing ring is connected to the same position of each conveyor belt to control the synchronous movement of the conveyor belts. The tofu enters between the conveyor belts from the inlet, and is conveyed towards the outlet end by the pushing ring controlling the conveyor belts, and passes through the sieve mesh to form filamentous tofu.

[0006] Preferably, four sets of conveyor belts are provided, forming a channel with a rectangular cross-section, and the cross-section of the corresponding cylinder is rectangular.

[0007] Preferably, the conveyor belt is provided with an extension part at the inlet end of the cylinder. The extension part is integrated with the conveyor belt. The extension parts of each conveyor belt are integrally in an inverted cone shape from the inlet of the cylinder to the outlet end. The extension part is used to place the tofu block and guide it into the cylinder.

[0008] Preferably, the length of the extension part along the feeding direction of the tofu is more than half of the length of both ends of the cylinder.

[0009] Preferably, legs are provided on the outer wall of the cylinder. The legs are used to support the cylinder to be placed horizontally and make one of the conveyor belts convey horizontally.

[0010] Preferably, mounting frames are provided at both ends of the outer wall of the cylinder in the width direction of the conveyor belt. The mounting frames slide directionally along the two ends of the cylinder through slide rails. Two feeding rollers are rotatably installed between the two groups of mounting frames on the same side of the conveyor belt. The two feeding rollers clamp the conveyor belt, and synchronous gears that are meshed with each other and have the same size are fixed at the ends of the two feeding rollers. An installation shaft is also rotatably connected to the mounting frame. A deflecting gear and an input gear are respectively fixed at both ends of the installation shaft. The deflecting gear is meshed with the synchronous gear corresponding to the feeding roller on the inner side of the conveyor belt. A rack meshed with the input gear is fixed on the outer wall of the cylinder along the tofu feeding direction. The transmission ratio from the input gear to the synchronous gear is greater than or equal to.

[0011] Preferably, the inclination angle between the extension part on the conveyor belt and the conveyor belt is 3° - 8°.

[0012] Preferably, an anti-deviation groove is formed on the inner side of the conveyor belt.

[0013] Preferably, the cross-section of the cylinder is a regular quadrilateral.

[0014] Preferably, a shaping blade is provided below the sieve mesh. The shaping blade corresponds to the size of the tofu block defined by the conveyor belt. The shaping blade is used to pre-cut the tofu to form a fixed size.

[0015] Compared with the prior art, the beneficial effects of the present invention are: By arranging multiple sets of conveyor belts on the conventional mold cylinder for shredded tofu, the conveyor belts are used to drive the feeding of the tofu blocks, thereby avoiding the gelatinization of the tofu blocks caused by excessive pressure and further preventing the formation of filaments; By using the conveyor belt to drive the feeding of the tofu blocks, the stability of the feeding tension can be effectively guaranteed. The feeding process is uniform and relatively stable, which can better cut the tofu blocks into filaments; By setting up structures such as a mounting frame, a synchronous gear, and an input gear, the present invention makes the movement direction of the pushing ring consistent with the feeding direction of the tofu cubes, which is more in line with the usage habits and convenient for use.

Detailed Embodiments

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figure 2The present invention provides a technical solution: a Wensi tofu cutting device, comprising a cylinder 1, the cylinder 1 is a hollow columnar body, with openings at both ends, one end is an inlet 1a, and the other end is an outlet 1b, the cylinder 1, the side walls of the cylinder 1 are located at both ends and rollers are installed, and a conveyor belt 2 is sleeved by the roller, and the conveyor belt 2 is provided with at least three groups, and the two side walls of the conveyor belt 2 in the width direction are close to each other, forming a polygonal shape, as one embodiment, Figure 5 The cylindrical body 1 is circular in cross section, and six sets of conveyor belts 2 are arranged on it to form a hexagonal shape. As another embodiment, Figure 6 As shown, the cross section of the columnar barrel 1 is triangular, and the corresponding conveyor belts 2 are set in three groups. The function of the barrel 1 is mainly to support and install the conveyor belts 2, so its shape is not necessarily polygonal and matches the number of conveyor belts 2. As a better choice, the barrel 1 is set to have a rectangular cross section. The rectangle is more convenient for installing the conveyor belt 2. The conveyor belt 2 also forms a rectangle, and on the other hand, it can better adapt to tofu. Generally, tofu is in a square shape when it is sold or packaged. The rectangular shape can handle the tofu block completely, and other shapes will produce scraps. See also Figure 10 A through slot is provided at a position near the outlet 1b on the side wall of the cylinder 1, and one of the rollers for installing the conveyor belt 2 is located at the through slot. This arrangement of the conveyor belt 2 can provide space for installing the screen 3 at the outlet 1b. The screen 3 is composed of a frame corresponding to the cylinder 1 and metal wires or metal sheets located in the frame. The metal wires or metal sheets are horizontally and vertically staggered to form a cutting net; See also Figure 2 The push ring 13 has a shape similar to the cross-sectional shape of the cylinder 1, and is sleeved on the outer wall side of the cylinder 1. The push ring 13 is fixedly connected to the same position of each conveyor belt 2, and the synchronous movement of the conveyor belt 2 is uniformly driven by the movement of the push ring 13. A guide slide is also provided between the push ring 13 and the cylinder 1 to avoid the inclination of the push ring 13 causing the movement of each conveyor belt 2 to be inconsistent; For details, see Figure 1 , Figure 2 and Figure 4, in a conventional Wensi tofu mold, the tofu block is mainly pushed forward by pressing with a pressing plate and cut into strips under pressure through a sieve 3. The inner wall of the cylinder 1 of the traditional mold is in direct contact with the tofu block. Therefore, when the tofu block is squeezed, the pressure of the tofu in the middle position is downward, while the tofu at the edge is upward due to the friction between the inner wall of the cylinder 1, and the pressure needs to overcome the friction. Therefore, a relatively large pressure is applied. If the pressure is too large, the tofu block will be squeezed into a paste or mud, and at this time, it can no longer be cut into strips or filaments. However, this solution avoids the limitation of friction through the conveyor belt 2, drives the movement of the tofu block through the movement of the conveyor belt 2, and does not require additional pressure on the tofu block. Therefore, it will not generate a large pressure on the tofu block to cause the tofu block to be in a paste or mud state. On the other hand, the conveyor belt 2 drives the tofu block through friction. As long as an external force is not applied quickly to the push ring 13, the friction of the conveyor belt 2 on the tofu block is very stable and will not cause the tofu to break, as Figure 4 shown, when the cylinder 1 is placed vertically, the self-gravity of the tofu block and the drive of the conveyor belt 2 make it move downward easily and then be cut into filaments through the sieve 3; Further, a bracket (not shown in the figure) can be provided at the outlet 1b end of the cylinder 1. The bracket supports the cylinder 1, which facilitates the setting of a container at the bottom to receive the shredded tofu. The bracket is preferably set as an independent individual spliced with the cylinder 1 to facilitate selective assembly according to usage habits; Furthermore, the push ring 13 can be fed in a non-manual way or by using a counterweight. The advantage of the counterweight method is that it can keep the tofu feeding at a relatively balanced and stable speed, thus ensuring the stability of the filament formation.

[0020] Refer to Figure 2 and Figure 10, in the component for clamping the tofu blocks formed by the conveyor belt 2, the size at the inlet 1a of the cylinder 1 is the same as the cross-sectional shape of the tofu blocks. As a result, it is difficult for the tofu blocks to enter the range wrapped by the cylinder 1, and it is easy to cause damage to the tofu blocks. Therefore, a connecting frame 14 is fixedly connected to the inlet 1a of the cylinder 1. The adjacent connecting frames 14 are connected and fixed by roller shafts or connecting plates. The connecting frame 14 faces away from the inlet 1a, and a roller shaft is rotatably connected to the outer end (the end far from the inlet 1a) of the connecting frame 14. The extension 201 of the conveyor belt 2 is supported by the roller shaft. The extension 201 and the conveyor belt 2 are integrated. Another set of turning roller shafts is arranged at the inlet 1a of the cylinder 1, so that there is an included angle α between the two sections of the conveyor belt 2. That is, in the half-sectional view of the conveyor belt 2, the included angle between the section of the conveyor belt 2 at the side wall of the cylinder 1 and the extension 201 is α. The preferred included angles α are 3°, 4°, 5°, 6°, 7° and 8°. Since it is bilateral, the overall included angle is 6° - 16° to facilitate the introduction of the tofu. The extensions 201 of each conveyor belt 2 are in an inverted cone shape as a whole. The extension 201 is convenient for guiding the tofu blocks, so that they can smoothly enter the interior of the cylinder 1; Furthermore, the straight-line length of the extension 201 is more than half of the length of the cylinder 1. Since the length between the two ends of the cylinder 1 matches the length of the tofu blocks, only when the length of the extension 201 reaches half of the length of the tofu can part of the tofu block be placed on the extension 201 of the conveyor belt 2 and the other part be suspended without breaking. Therefore, it is preferred that the length of the extension 201 exceeds 2 / 3 of the length of the tofu block; Specifically, during use, the cut tofu blocks are directly placed on any one of the conveyor belts 2, and the cylinder 1 is placed obliquely or horizontally, so that the conveyor belt 2 carrying the tofu blocks is at the lowest relative position. Push the push ring 13 to move the conveyor belt 2. When the tofu blocks enter the cylinder 1, the cylinder 1 can be placed vertically or continue to be placed obliquely or horizontally to continuously feed the tofu blocks; In the above solution, when used in a horizontal state, the cylinder 1 can be as Figure 2 and Figure 3 shown, with legs 4 provided. The legs 4 support the cylinder 1 for use. In the supported state of the legs 4, it is in the state as Figure 3 , so that the push ring 13 and the conveyor belt 2 are both off the ground or the table to prevent affecting the use.

[0021] Refer to Figure 2 , Figure 7 , Figure 8 and Figure 9, in the case of only adopting the pushing ring 13, the moving direction of the pushing ring 13 is opposite to the feeding direction of the tofu block, which is relatively contrary to the usage habit. Therefore, multiple groups of mounting frames 5 are arranged on the outer wall of the cylinder body 1, and each group contains two mounting frames 5. The mounting frames 5 are located at the same vertical height of the cylinder body 1. The two mounting frames 5 in the same group are respectively located at both ends of the width direction of the conveyor belt 2. Two feeding rollers 7 are rotatably connected between the mounting frames 5 in the same group through bearings. One feeding roller 7 is located outside the conveyor belt 2, and the other is located inside the conveyor belt 2, so as to clamp the conveyor belt 2. Synchronous gears 8 that mesh with each other are fixedly installed at the ends of the two feeding rollers 7. All parameters of the two synchronous gears 8 are the same. The synchronous gears 8 cause the two feeding rollers 7 to rotate synchronously in opposite directions. An installation shaft 9 is also rotatably connected to the mounting frame 5 through a bearing. Both ends of the installation shaft 9 extend beyond the end faces of the mounting frame 5, and a deflecting gear 10 and an input gear 11 are fixedly connected to both ends of the installation shaft 9 respectively. The deflecting gear 10 meshes with the synchronous gear 8 corresponding to the feeding roller 7 located inside the conveyor belt 2, so as to make the moving direction of the conveyor belt 2 on the outer wall of the cylinder body 1 opposite to the moving direction of the mounting frame 5; An annular groove with an open cross-section is formed on the side wall of the mounting frame 5 close to the outer wall of the cylinder body 1. Correspondingly, a sliding rail 6 is fixed on the outer wall of the cylinder body 1. The sliding rail 6 is slidably oriented and matched with the annular groove on the mounting frame 5. A rack 12 extending in the same direction as the sliding rail 6 is also fixed on the outer wall of the cylinder body 1. The rack 12 meshes with the input gear 11. Adjacent two mounting frames 5 in different groups are fixed through a connecting plate, and the mounting frame 5 is also connected to the pushing ring 13 through the connecting plate; Specifically, when pushing the tofu block, only need to push the pushing ring 13 along the tofu feeding direction. The pushing ring 13 makes the mounting frame 5 move along the tofu feeding direction. When moving, the input gear 11 rotates ( Figure 9 rotates counterclockwise in the shown state), and then the deflecting gear 10 drives the synchronous gear 8, so that Figure 9 the left and right synchronous gears rotate counterclockwise and clockwise respectively. Because the length of the cylinder body 1 is limited, the moving amount of the mounting frame 5 is limited. And the feeding amount of the tofu block is greater than the length of the cylinder body 1. The minimum feeding amount state is that the end of the initial tofu block is located at the inlet 1a of the cylinder body 1. At this time, the tofu block needs to be fed by an amount equal to its own length to be completely filled inside the cylinder body 1, and then it still needs an amount equal to its own length for wire drawing. Therefore, the transmission ratio from the input gear 11 to the synchronous gear 8 should be greater than or equal to 2. Therefore, in order to complete the feeding, the transmission ratio needs to be greater than 2 Refer to Figure 11, the size of the tofu block in the normal buying and selling state is larger than the size optimally used in this solution. Because the larger the size, the more unstable the wire drawing, and the greater the self-weight, it is easy to directly fall off. Therefore, a shaping blade 301 with a predetermined specification is set on the sieve 3 to pre-cut the tofu. The shaping blade 301 extends beyond the lower surface of the sieve 3. The sieve 3 can be taken down separately, and cutting lines are generated on the surface of the whole tofu through the shaping blade 301 to demarcate the size, thus facilitating the user to cut the tofu of a predetermined size.

[0022] Refer to Figure 12 , in order to prevent the conveyor belt 2 from running off track during the back-and-forth movement, an anti-deviation groove 202 is opened in the middle of the inner side wall of the conveyor belt 2, and a protruding step is correspondingly set on the roller shaft to fit the anti-deviation groove 202.

[0023] Furthermore, a handle can also be fixedly connected to the outer wall of the cylinder 1. The handle is convenient for the user to hold, and while being held with one hand, the push ring 13 can be pushed by the thumb.
