Description

Technical Field

[0001] This invention relates to the field of equipment technology for processing tofu skin, and particularly to a mechanism for rolling tofu skin. Background Technology

[0002] Tofu skin rolls are a type of bean curd product, typically deep-fried until golden brown and crispy, resulting in an excellent texture. Traditionally, production involves manually removing the tofu skin, deep-frying, and rolling it, leading to very low efficiency. Automatic tofu skin frying equipment is now available, such as the tofu skin processing equipment disclosed in Chinese Utility Model Patent CN213344125U. This equipment includes a frying device comprising a frying frame with a rotating disc frame driven by a divider. Several clamping components for gripping and releasing the tofu skin are mounted on the disc frame, their movement tracing the inside of the oil pan. Then, the tofu skin on the clamping handles is rolled up inside the rolling drum via a sprocket and gear on the clamping components engaging with a chain on a chain drive component. Under the adhesive force of a rubber block, the tofu skin roll falls from the rolling drum, completing the tofu skin roll forming process.

[0003] However, after the rotten skin on the clamping handle comes out of the oil pan, it is suspended in the air and is easily damaged at the entrance of the coil. At the same time, the clamping assembly includes a sleeve rotatably connected inside the outer shell, a sliding rod slidably connected inside the sleeve, a spring connecting the sleeve and the sliding rod, a clamping frame fixedly installed on the sleeve, and two clamping handles rotatably connected to the clamping frame. The two clamping handles are connected to two swing rods between the two clamping handles and the sliding rod, respectively. One end of the swing rod is hinged to the sliding rod, and the other end is hinged to the corresponding clamping handle. When the first drive pushes the sliding rod, the two clamping handles open into a funnel shape inside the coil. When the rotten skin roll is taken out, it is easy to open the rotten skin roll, which affects the quality of the rotten skin roll.

[0004] Therefore, in order to improve the forming quality of tofu skin rolls, it is necessary to make necessary modifications to the frying device in the above-mentioned tofu skin processing equipment in order to improve the forming quality and practicality of tofu skin rolls. Summary of the Invention

[0009] Furthermore, a sliding rod is slidably provided inside the sleeve, and a compression spring for resetting the sliding rod is provided between the sliding rod and the sleeve; a clamping frame is provided at the front end of the sleeve; two parallel cranks are hinged to the clamping handle, and the two cranks are hinged to the clamping frame at equal distances; a connecting rod for driving the corresponding crank to rotate is hinged to the front end of the sliding rod; a push cylinder is provided at the rear end of the sliding rod.

[0010] Furthermore, the chain drive assembly also includes sprockets B rotatably connected to both ends of the mounting beam and driven by the chain, wherein one of the sprockets B is driven to rotate by a servo motor.

[0011] Furthermore, the rollers are a guide roller assembly, and each end of the guide roller assembly is provided with a tensioning component. Two tensioning components are symmetrically arranged with respect to the center line of the sector plate. The tensioning component includes a pressure rod hinged to the sector plate. One end of the pressure rod is rotatably connected to a tensioning wheel, and the other end is provided with a tension spring in a stretched state. One end of the tension spring is provided with a support rod A, and the other end is provided with a support rod B. Support rod A is bolted to the pressure rod. Support rod B is bolted to the sector plate.

[0012] Furthermore, the guide skin assembly also includes a support base, which has a vertical U-shaped groove on one side of the guide skin groove; both sides of the guide skin groove are bolted and fixed to the inner wall of the U-shaped groove.

[0013] Furthermore, two elongated holes A are provided on the side wall of the U-shaped groove for adjusting the vertical height of the guide groove; the bottom of the U-shaped groove is provided with several threaded push rods, which are used to push against the bottom of the guide groove.

[0014] Furthermore, an adjusting plate is slidably provided above the bottom of the guide groove; a pushing component is provided on the front side of the guide groove; the pushing component is used to drive the adjusting plate to move parallel within the guide groove.

[0015] Furthermore, the pushing assembly includes an adjusting seat and a longitudinal screw; the screw has symmetrically arranged optical axes that slide through the front side of the guide groove on both sides; the rear end of the screw has a connecting seat; both the optical axes and the connecting seat are fixed to the front end of the adjusting plate; the adjusting seat is fixed to the front side of the guide groove; the adjusting seat is threadedly connected to the screw; the screw is located above the guide groove; the front end of the screw has a handle, and the rear end is coaxially arranged with the connecting seat with a lubricating bearing; the connecting seat has a retaining ring for limiting the longitudinal movement of the screw.

[0016] Furthermore, the roll includes a slide cylinder mounted on top of the mounting base; a connecting plate is provided on the top of the slide on the slide cylinder; a clamping cylinder is provided at the bottom of the connecting plate, and a longitudinal beam is bolted to the clamping jaws on the clamping cylinder; a baffle is provided at the front end of the longitudinal beam, and a U-shaped opening matching the size of the clamping handle is opened in the middle of the baffle along the transverse direction; a clamping cylinder with an arc cross-section is bolted longitudinally to the rear end of the baffle, and the two clamping cylinders can be combined into a cylinder for holding the rotten skin roll.

[0017] Furthermore, the top and bottom sides of the clamping cylinders are smoothly transitioned with outwardly curved arc-shaped portions; a first gap of value a is provided between the two clamping cylinders after they are joined together, and a second gap of value b is provided between the two baffles after they are joined together, where a≤b, 2mm≤b≤2.5mm; the directions of the first gap and the second gap are consistent; the angle between the direction of the second gap and the vertical direction is β, where 5°≤β≤6°.

[0018] Compared with the prior art, the beneficial effects of this invention are as follows: By tensioning one side of the chain with several rollers and coaxializing it with the disc frame, the rotisserie sheet roll on the clamping handle is smoothly rolled along the guide groove under the drive of sprocket A before entering the coil, completing the pre-rolling and forming of the rotisserie sheet. This avoids scratching the rotisserie sheet during forming inside the coil and ensures the processing quality of the rotisserie sheet roll. The use of two parallel opening and closing clamping handles prevents the rotisserie sheet roll from being stretched open inside the coil, improving the regularity of the rotisserie sheet roll. The coordinated operation of the overall structure reduces factors affecting the quality of the rotisserie sheet roll and improves the overall practicality. Attached Figure Description

[0033] Example

[0034] Please see Figures 1 to 11 The present invention provides a tofu skin rolling mechanism, including a disc frame 1, a skin guide assembly 4 and a rolling cylinder 5. The disc frame 1 is evenly distributed with clamping assemblies 2 driven to rotate by a chain transmission assembly 3, and the number of clamping assemblies 2 is three.

[0035] The clamping assembly 2 includes a sleeve 22 rotatably connected to a fixed base 21, which is bolted to a disc frame 1; the sleeve 22 is provided with a sprocket A29, and the front end of the sleeve 22 is provided with two parallel opening and closing clamping handles 26.

[0036] The chain drive assembly 3 includes a chain 33 rotatably mounted on a mounting beam 31. A sector plate 34 is provided at the front end of the mounting beam 31. Several rollers 35 are rotatably connected to the sector plate 34 and are coaxially arrayed relative to the disc frame 1. The rollers 35 are located inside the chain 33 and rotate in contact with the chain 33. The chain 33 on one side of the roller 35 meshes with the sprocket A29.

[0037] The guide belt assembly 4 includes an arc-shaped guide belt groove 42. Several rollers 35 can tension the chain 33. At the same time, when the corroded skin on the clamp 26 slides along the guide belt groove 42, since the chain 33 on one side of the roller 35 is coaxial with the disc frame 1, the clamping assembly 2 rolls on the chain 33 through the sprocket A29, so that the corroded skin is pre-rolled and formed, avoiding scratches and damage when entering the coil, thus ensuring the quality of the corroded skin roll.

[0038] The chain drive assembly 3 here also includes sprockets B32 rotatably connected to both ends of the mounting beam 31 and driven by the chain 33. One of the sprockets B32 is driven to rotate by the servo motor 8 to ensure the rotation of the chain 33. The aforementioned disc frame 1 is driven to rotate by the divider 11, and the details will not be elaborated further.

[0039] In one embodiment of the present invention, a slide rod 24 is slidably provided inside the sleeve 22, and a compression spring 28 for resetting the slide rod 24 is provided between the slide rod 24 and the sleeve 22; a clamping frame 23 is provided at the front end of the sleeve 22; two parallel cranks 25 are hinged to the clamping handle 26, and the two cranks 25 are hinged at equal distances to the clamping frame 23; a connecting rod 27 for driving the corresponding crank 25 to rotate is hinged to the front end of the slide rod 24; a push cylinder 6 is provided at the rear end of the slide rod 24.

[0040] The two cranks 25 and the corresponding clamps 26 form a parallelogram mechanism, namely a double crank mechanism. Under the push of the push cylinder 6, the slide rod 24 drives the two clamps 26 to open in parallel through the connecting rod 27, so that the rotten skin roll will not be stretched open in the rolling drum 5 due to the opening of the clamps 26, thus ensuring the overall regularity of the rotten skin roll and improving the quality of the rotten skin roll.

[0041] An elastic steel plate 61 can be provided between the push cylinder 6 and the slide rod 24, and the lower end of the elastic steel plate 61 is bolted to the machine body. A ball nut can be provided at the rear end of the slide rod 24, and the ball nut can slide on the elastic steel plate 61 so that the push cylinder 6 can push the slide rod 24 more effectively.

[0042] As an embodiment of the present invention, a plurality of rollers 35 form a guide wheel assembly, and tensioning components 7 are provided at both ends of the guide wheel assembly. The two tensioning components 7 are symmetrically arranged with respect to the center line of the sector plate 34. The tensioning component 7 includes a pressure rod 71 hinged to the sector plate 34. One end of the pressure rod 71 is rotatably connected to a tensioning wheel 72, and the other end is provided with a tension spring 75 in a stretched state. One end of the tension spring 75 is provided with a support rod A73, and the other end is provided with a support rod B74. The support rod A73 is bolted to the pressure rod 71. The support rod B74 is bolted to the sector plate 34.

[0043] The pressure bar 71 here can be provided with several threaded holes 76 for adjusting the support bar A73. The tension of the chain 33 by the pressure bar 71 can be adjusted according to the usage requirements to ensure stable meshing between the chain 33 on the roller 35 side and the sprocket A29.

[0044] As an embodiment of the present invention, the guide skin assembly 4 further includes a support base 41, which has a vertical U-shaped groove on one side of the guide skin groove 42; both sides of the guide skin groove 42 are bolted and fixed to the inner wall of the U-shaped groove.

[0045] Two elongated holes A can be opened on the side wall of the U-shaped groove to adjust the vertical height of the guide groove 42; the bottom of the U-shaped groove is provided with several threaded push rods 49, which are used to push against the bottom of the guide groove 42 to ensure the stability of the position of the guide groove 42.

[0046] In addition, an adjusting plate 43 is slidably provided above the bottom of the guide groove 42; a pushing component is provided on the front side of the guide groove 42; the pushing component is used to drive the adjusting plate 43 to move parallel within the guide groove 42.

[0047] The actuating assembly here includes an adjusting seat 44 and a longitudinal screw 45; the screw 45 has symmetrically arranged optical shafts 46 that slide through the front side of the guide groove 42 on both sides; the rear end of the screw 45 has a connecting seat 47; the optical shafts 46 and the connecting seat 47 are both fixed to the front end of the adjusting plate 43; the adjusting seat 44 is fixed to the front side of the guide groove 42; the adjusting seat 44 is threadedly connected to the screw 45; the screw 45 is located above the guide groove 42; the front end of the screw 45 has a handle 48, and the rear end is coaxially arranged with the connecting seat 47 to form a lubricating bearing; the connecting seat 47 has a retaining ring for limiting the longitudinal movement of the screw 45.

[0048] By adjusting the plate 43 and sliding it longitudinally along the bottom of the guide groove 42, the width of the guide groove 42 used to guide the rotten skin can be adjusted according to the width of different batches of rotten skin, so as to ensure that the rotten skin roll is flat and pre-rolled.

[0049] The front end of the optical axis 46 here can be threaded with a cover to prevent the optical axis 46 from disengaging from the guide groove 42.

[0050] As an embodiment of the present invention, the roll 5 includes a slide cylinder 52 disposed on the top of the mounting base 51; a connecting plate 53 is provided on the top of the slide of the slide cylinder 52; a clamping cylinder 54 is provided at the bottom of the connecting plate 53, and a longitudinal beam 55 is bolted to the clamping claw on the clamping cylinder 54; a baffle 56 is provided at the front end of the longitudinal beam 55, and a U-shaped opening 59 matching the size of the clamping handle 26 is opened in the middle of the baffle 56 in the transverse direction; a clamping cylinder 57 with an arc-shaped cross section is bolted to the rear end of the baffle 56 in the longitudinal direction, and the two clamping cylinders 57 can be combined into a cylinder for holding the rotten skin roll.

[0051] The clamping cylinder 54 drives the two clamping cylinders 57 to merge. The pre-rolled tofu skin roll on the clamping handle 26 is located inside the two clamping cylinders 57. At this time, the servo motor 8 drives the chain transmission assembly 3, and the clamping handle 26 drives the pre-rolled tofu skin roll to complete the final forming. Finally, the servo motor 8 stops running and pushes the cylinder 6 to push the slide bar 24. The two clamping handles 26 open in parallel, and the slide cylinder 52 drives the two clamping cylinders 57 to move longitudinally. Under the action of the baffle 56, the two clamping handles 26 slide out from the U-shaped opening 59 on the baffle 56. At this time, under the action of the compression spring 28, the two clamping handles 26 close in parallel. The tofu skin roll remains inside the two clamping cylinders 57 until the two clamping cylinders 57 open, and the tofu skin roll falls into the material channel to enter the next oil-removing process. The entire process can complete the transfer of the tofu skin roll without the existing adhesive blocks, ensuring the overall quality of the tofu skin roll.

[0052] The clamping cylinder 57 has outwardly curved arc-shaped portions on both its top and bottom sides, forming a smooth transition. A first gap of value 'a' is provided between the two clamping cylinders 57 after they are joined, and a second gap of value 'b' is provided between the two baffles 56 after they are joined, where a ≤ b, 2mm ≤ b ≤ 2.5mm. The directions of the first and second gaps are consistent. The angle between the direction of the second gap and the vertical direction is 'β', 5° ≤ β ≤ 6°, to prevent the rotten skin roll from being damaged by the clamping cylinders 57 when it falls into the material channel, further ensuring the overall quality of the rotten skin roll. The inclined first and second gaps prevent the edges of the rotten skin roll from being exposed to the clamping cylinders 57 and damaged, and the arc-shaped portions on the clamping cylinders 57 prevent the rotten skin roll from being scratched when it falls into the material channel.

[0053] The front end of the aforementioned longitudinal beam 55 may also be provided with a mounting plate 58, which has several elongated holes B along the vertical direction and is bolted to the longitudinal beam 55 through the elongated holes B; the clamping plate 56 is bolted and fixed to the mounting plate 58 to facilitate the adjustment of the vertical position of the clamping cylinder 57.

[0054] This invention can be summarized in other specific forms that do not depart from the spirit or essential features of the invention. Therefore, in all respects, the above embodiments of the invention should be considered illustrative only and not limiting, while the claims define the scope of the invention. The foregoing description does not define the scope of the invention; therefore, any changes within the meaning and scope equivalent to the claims should be considered to be included within the scope of the claims.
