Detailed implementation manners

[0028] The following describes the detailed implementation manners of the present invention with reference to the accompanying drawings and embodiments. However, the following embodiments are only used to illustrate the present invention in detail and do not limit the scope of the present invention in any way.

[0029] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. The "first", "second", etc. involved in this application are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence.

[0030] The tofu skin sorting machine provided by the embodiment of the present invention is mainly used to stack and sort the processed and dispersed tofu skins into stacks, so as to facilitate the storage, handling, and sale of tofu skins.

[0031] Embodiment 1:

[0032] A tofu skin sorting machine, please refer to Figures 1 to 6 。

[0033] The tofu skin sorting machine provided by the embodiment of the present invention includes a frame 1, and the frame 1 is used to install and support other components, mechanisms, and devices of the tofu skin sorting machine, so that each component, mechanism, and device form an integral whole that can cooperate with each other to achieve corresponding functions. In this embodiment, the frame 1 is of a split design, and in other embodiments, it can also be designed as an integral type.

[0034] As Figure 1 and Figure 2 shown, a tofu skin conveyor belt 2 is installed on the frame 1, and a tofu skin stacking device 3 is arranged beside the tofu skin conveyor belt 2. The tofu skin conveyor belt 2 is driven by a motor and is used to convey the tofu skins one by one to the tofu skin stacking device 3, and then the tofu skin stacking device 3 stacks the tofu skins one by one together. In this embodiment, the driving motor of the mechanical gripper and the driving motor of the cooling transmission chain both use servo motors. In other embodiments, stepper motors can also be used.

[0035] The tofu skin stacking device 3 includes a tofu skin receiving table 31, a mechanical gripper 32 capable of clamping the tofu skin, and a transmission component for driving the mechanical gripper 32 to grab the tofu skins conveyed by the tofu skin conveyor belt 2 back and forth and stack them on the tofu skin receiving table 31.

[0036] In this embodiment, the tofu skin receiving table 31 includes a lifting device, which is an electric jack 311. A top plate 312 is provided on the electric jack 311. The electric jack 311 is driven by a motor 313 to lift and lower the screw rod, and the lifting height can be finely adjusted. An induction component 314 is arranged on the frame 1 on the side of the top plate 312. The induction component 314 can be an infrared sensor, a photoelectric sensor, etc. When the induction component 314 senses that a tofu skin is falling, the motor 313 drives the top plate 312 to descend to a height corresponding to the thickness of a tofu skin.

[0037] The transmission component includes transmission lines arranged on both sides of the mechanical gripper 32. In this embodiment, the transmission line is a transmission chain 33. A total of four mechanical grippers 32 are provided between the transmission chains 33 on both sides. During the rotation of the transmission chain 33, the four mechanical grippers 32 can alternately grab the tofu skin.

[0038] Combined Figure 3 As shown, in this embodiment, the mechanical gripper 32 includes supports 321 on both sides. A fixed shaft 322 and a rotating shaft 323 are arranged between the supports 321. A plurality of gripper claws 324 are provided on the rotating shaft 323. A positioning device is arranged between the rotating shaft 323 and the fixed shaft 322. In this embodiment, the positioning device includes a positioning spring 326, and a spring is also arranged between each gripper claw 324 and the rotating shaft 323, so that the biting force between each gripper claw 324 and the fixed shaft 322 can be adjusted. For the convenience of representation, Figure 3 the gripper claw 324 and the fixed shaft 322 are in an open state.

[0039] The positioning spring 326 is to restrict the rotating shaft 323 so that the rotating shaft 323 does not rotate freely, so that the rotating shaft 323 is in a stable state relative to the fixed shaft 322. As Figure 3 shown, a guide shaft 3262 is sleeved in the positioning spring 326. A collar 3231 is fixedly arranged on the rotating shaft 323. An extension plate 3261 is arranged on the fixed shaft 322. The lower end of the guide shaft 3262 is hinged to the collar 3231, and the upper end is inserted into the hole in the extension plate 3261. When an external force is applied to the rotating shaft 323 to make the rotating shaft 323 rotate clockwise, the gripper claw 324 and the fixed shaft 322 can open, and at this time the positioning spring 326 is compressed. When the applied external force is eliminated, the rotating shaft 323 rotates back to the original state, and the gripper claw 324 and the fixed shaft 322 can close.

[0040] As Figure 3 shown, a radial handle 327 is arranged at one end of the rotating shaft 323. The inside of the support 321 is hollow, and the lower end of the handle 327 extends out of the support 321. Combined Figure 1As shown in the figure, a first blocking projection 11 is correspondingly provided on the frame 1 near the dried bean curd skin conveyor belt 2. The first blocking projection 11 is provided on one side of the frame 1. When the drive chain 33 drives the mechanical gripper 32 to move so that the turning handle 327 touches the first blocking projection 11, the force on the turning handle 327 causes the rotating shaft 323 to rotate, thereby causing the gripper 324 and the fixed shaft 322 to open. At this time, the frontmost dried bean curd skin on the dried bean curd skin conveyor belt 2 falls, and the front end of the falling dried bean curd skin falls between all the open grippers 324 and the fixed shaft 322. As the drive chain 33 continues to rotate, the turning handle 327 leaves the first blocking projection 11, and the gripper 324 and the fixed shaft 322 on the mechanical gripper 32 close to grasp the dried bean curd skin.

[0041] As Figure 2 shown, a slide plate 21 is provided at the front end of the dried bean curd skin conveyor belt 2, which can guide the falling dried bean curd skin between the front grippers 324 and the fixed shaft 322.

[0042] When the mechanical gripper 32 holding the dried bean curd skin 4 moves above the dried bean curd skin receiving table 31, the lower end of the dried bean curd skin 4 is placed on the right side of the top plate 312. Combining Figure 1 shown, a second blocking projection 12 is provided on the frame 1 diagonally above the dried bean curd skin receiving table 31. As the mechanical gripper 32 continues to move to the left, the turning handle 327 on the mechanical gripper 32 touches the second blocking projection 12, and the gripper 324 and the fixed shaft 322 open to release the dried bean curd skin 4. The left end of the dried bean curd skin 4 falls on the left side of the top plate 312. In this way, the dried bean curd skins can be laid flat on the top plate 312 for stacking.

[0043] As Figure 1 shown, a first sensing component 13 for controlling the movement of the mechanical gripper 32 is provided above the front end of the dried bean curd skin conveyor belt 2, and a second sensing component 14 for controlling the mechanical gripper 32 to be in the waiting position is provided on the dried bean curd skin stacking device 3. The first sensing component 13 and the second sensing component 14 are sensors.

[0044] The drive chain 33 is driven by a motor. After the dried bean curd skin stacking device 3 grabs a dried bean curd skin and places it on the dried bean curd skin receiving table 31, as the drive chain 33 continues to rotate, the second sensing component 14 senses the incoming mechanical gripper 32, and the motor controls the drive chain 33 to move the mechanical gripper 32 to a suitable position to wait. The dried bean curd skin conveyor belt 2 conveys a dried bean curd skin at regular intervals. When the first sensing component 13 senses that a dried bean curd skin is being conveyed, the motor controls the drive chain 33 to rotate, causing the mechanical gripper 32 in the waiting position to move forward. When the mechanical gripper 32 opens, the front end of the conveyed dried bean curd skin just falls into the mechanical gripper 32 and is grabbed.

[0045] Furthermore, as Figure 1 and Figure 2As shown, the dried bean curd skin finishing machine further includes a dried bean curd skin cooling device 5, which is used to cool the freshly processed hot dried bean curd skin. Only after cooling can the dried bean curd skins be stacked together to prevent spoilage.

[0046] The dried bean curd skin cooling device 5 includes multiple placing rods 51 for placing the dried bean curd skins. Cooling transmission lines are respectively arranged at both ends of the placing rods 51. In this embodiment, the cooling transmission line is a cooling transmission chain 52. In other embodiments, the cooling transmission line can adopt a transmission belt, such as a toothed belt. A plurality of first limiting tabs 521 are arranged at intervals on the cooling transmission chain 52, and the end of each placing rod 51 is arranged between adjacent first limiting tabs 521, so that the placing rod 51 can be kept stable during the transmission on the cooling transmission chain 52.

[0047] As Figure 4 shown, both ends of the placing rod 51 are square parts 511, and the middle part is a round tube part 512. The square parts 511 are placed on the cooling transmission chain 52, which can prevent the placing rod 51 from rolling over, so that the dried bean curd skins on the placing rod 51 will not roll off.

[0048] As Figure 1 shown, a dried bean curd skin flattening mechanism 53 is arranged between the dried bean curd skin cooling device 5 and the dried bean curd skin conveyor belt 2 to flatten the dried bean curd skins on the placing rods 51 onto the dried bean curd skin conveyor belt 2.

[0049] The dried bean curd skin flattening mechanism includes support rods 534 respectively arranged on the left and right sides above the dried bean curd skin conveyor belt 2, and multiple placing rods 51 for placing on the support rods 534. The dried bean curd skins are placed on the placing rods 51, and both ends of the placing rod 51 are respectively placed on the support rods 534, so that the lower end of the dried bean curd skin on the placing rod 51 drives the dried bean curd skin to fall and flatten on the dried bean curd skin conveyor belt 2 by friction with the upper surface of the dried bean curd skin conveyor belt 2. After the dried bean curd skin falls, its two sides are parallel to the two sides of the dried bean curd skin conveyor belt 2 and generally will not tilt.

[0050] In this embodiment, support plates 5341 are arranged on the support rods 534 on both sides, and roller groups are respectively installed on the inner sides of the support plates 5341 through rotating shafts. The setting of the roller groups is beneficial to promoting the falling of the dried bean curd skins on the placing rods 51.

[0051] Combined with Figure 5 shown, each side of the roller group includes a first driven roller 5311, a second driven roller 5312 and a driving roller 5313. The first driven roller 5311, the second driven roller 5312 and the driving roller 5313 are all rollers with a friction surface on the outer peripheral surface. As Figure 1As shown in the figure, a driving motor 5342 is provided outside the movable frame 531. When the frontmost cross bar 51 on the cooling transmission chain 52 falls onto the roller groups on both sides, the driving motor 5342 can drive the driving roller 5313 to rotate. The driving roller 5313 then drives the first driven roller 5311 and the second driven roller 5312 to rotate clockwise. Since the main body of the cross bar is the round tube part 512, the rotation of the roller groups can drive the cross bar 51 to rotate, causing the tofu skin on the cross bar 51 to fall off.

[0052] Furthermore, the tofu skin flattening mechanism 53 further includes a movable support 531. The support rod 534 is installed on the movable support 531. The movable support 531 is installed on the frame 1 through the first driving component 532. The first driving component 532 is a cylinder. Two stop bars 533 are also provided on the front side of the movable support 531. When the tofu skin erected on the cross bar 51 that has fallen onto the roller groups falls off, the first driving component 532 drives the movable support 531 to move forward. The two ends of the cross bar 51 are blocked from the roller groups by the stop bars 533. Then the first driving component 532 drives the movable support 531 to move backward. The tofu skin flattening mechanism 53 can then immediately flatten the tofu skin on the next cross bar, and so on in a cycle.

[0053] Cooling devices such as fans and air conditioners can be provided beside the tofu skin cooling device 5 to promote the rapid cooling of the hot tofu skin.

[0054] Furthermore, the tofu skin sorting machine further includes a cross bar return device 6. The cross bar return device 6 is arranged side by side with the tofu skin cooling device 5. The cross bar return device 6 is used to continuously return the cross bars that have fallen from the tofu skin flattening mechanism 53 to the rear end of the tofu skin cooling device 5, enabling the cross bars to be recycled.

[0055] As Figure 1 and Figure 2 shown, the cross bar return device 6 includes two cross bar return transmission lines provided on the side of the cooling transmission chain 52. In this embodiment, the cross bar return transmission line is the cross bar return transmission chain 61. As Figure 5 shown, a first receiving groove for receiving the falling cross bar 51 is provided below the stop bar 533. The first receiving groove includes a first right half groove 62 and a first left half groove 63. The first right half groove 62 is located below the roller group on the support rod 534. Two first inclined guide rods 621 are respectively provided at the rear ends of both sides of the first right half groove 62. The cross bar on the roller group can fall into the first right half groove 62 along the first inclined guide rods 621. The front side of the first receiving groove is welded to the frame, and the front side is blocked by the frame to prevent the cross bar from rolling due to inertia during the falling process.

[0056] Combined with Figure 1As shown in the figure, the first left half groove 63 is located above the rod return transmission chain 61. A second driving mechanism 64 is provided beside the first right half groove 62. The second driving mechanism 64 is a rodless cylinder. A lever 642 is installed on the moving block 641 of the rodless cylinder. When the moving block 641 moves along the guide rod 643, the lever 642 can send the rod received in the first right half groove 62 to the first left half groove 63.

[0057] Second limiting flanges 611 are provided at intervals on the rod return transmission chain 61. A notch 65 for passing the second limiting flanges is formed in the middle of the first receiving groove. The length of the rod is longer than that of the first left half groove 63. When the rod is located in the first left half groove 63, one end of the rod is located in the notch 65 and the other end is located outside the first left half groove 63. In this way, during the rotation of the rod return transmission chain 61, the second limiting flange 611 can take out the rod in the first left half groove 63 and always bring the rod to the rear end of the tofu skin cooling device 5.

[0058] Furthermore, a rod re - setting device 7 for re - setting the returned rod on the cooling transmission chain 52 is provided at the rear end of the rod return device 6. As Figure 6 shown, the rod re - setting device 7 includes a second receiving groove for receiving the rod that drops from the rear end of the rod return transmission chain 61. The second receiving groove includes a second left half groove 71 and a second right half groove 72. A retaining rod is provided on the frame 1 on one side of the second left half groove to prevent the rod from jumping out of the second receiving groove 72 when it drops.

[0059] A third driving mechanism 73 for sending the rod received in the second left half groove 71 to the second right half groove 72 is provided beside the second left half groove 71. The third driving mechanism 73 is a rodless cylinder. A lever 732 is installed on the moving block 731 of the rodless cylinder. When the moving block 731 moves along the guide rod 733, the lever 732 can send the rod received in the second left half groove 71 to the second right half groove 72.

[0060] The second right half groove 72 is located obliquely below the rear end of the cooling transmission chain 52. A pushing mechanism for pushing the rod received in the second right half groove 72 onto the cooling transmission chain 52 is provided obliquely below the second right half groove 72. In this embodiment, the pushing mechanism includes a top - pushing cylinder 741. A cross bar 742 is provided at the top end of the top - pushing cylinder 741. Top rods 743 are respectively provided at both ends of the cross bar 742.

[0061] A notch 75 is provided in the middle of the second receiving groove. The length of the rod is longer than that of the second right half groove 72. When the rod is located in the second right half groove 72, one end of the rod is located in the notch 75 and the other end is located outside the second right half groove 72. The top rods 743 on both sides of the pushing mechanism respectively push both ends of the rod upward to push the rod onto the cooling transmission chain 52 between two adjacent first limiting flanges 521.

[0062] Second inclined guide rods 711 are respectively arranged at both front ends of the second right half groove 72. When the pushing mechanism pushes the lifting rod upward, the second inclined guide rods 711 play a guiding role.

[0063] The pushing mechanism in this embodiment is in the upward pushing mode. In other embodiments, according to the positional relationship between the lifting rod return device and the dried bean curd skin cooling device, other pushing modes such as horizontal pushing can also be designed.

[0064] Furthermore, the dried bean curd skin arranging machine further includes a dried bean curd skin cooling conveyor belt 8. The dried bean curd skin cooling conveyor belt 8 is used to convey hot dried bean curd skins forward one by one. The front end of the dried bean curd skin cooling conveyor belt 8 is close to the rear end of the cooling transmission chain 52. When the foremost dried bean curd skin on the dried bean curd skin cooling conveyor belt 8 drops from its front end, the pushing mechanism just pushes the lifting rod in the second right half groove 72 upward. During the upward pushing process of the lifting rod, the dried bean curd skin that drops at the front end of the dried bean curd skin cooling conveyor belt 8 is laid on the lifting rod. As the pushing mechanism continues to push upward, the lifting rod with the dried bean curd skin laid on it is finally pushed onto the cooling transmission chain 52. In this way, it can be realized that hot dried bean curd skins are automatically laid on the cooling transmission chain 52 one by one.

[0065] A third sensing component 15 is arranged at the front end of the dried bean curd skin cooling conveyor belt 8. When the third sensing component 15 senses that there is a dried bean curd skin, it can correspondingly control the action of the pushing mechanism in the upper lifting rod device 7, so that the dropping time of the dried bean curd skin matches the action time of the pushing mechanism. After each dried bean curd skin drops at the front end of the dried bean curd skin cooling conveyor belt 8, a spare lifting rod is immediately sent to the second right half groove 72.

[0066] In addition, the cooling transmission chain 52 and the lifting rod return transmission chain 61 are respectively driven by motors. The distances between adjacent first limit flanges 521 on the cooling transmission chain 52 are the same, so that the distances between adjacent lifting rods 51 are the same. By controlling the rotation speed of the cooling transmission chain 52, the action frequency of the dried bean curd skin flattening mechanism is matched with the speed of the lifting rods dropping on the cooling transmission chain 52.

[0067] The distances between adjacent second limit flanges 611 on the lifting rod return transmission chain 61 are also the same, and the distances between adjacent second limit flanges 611 on the lifting rod return transmission chain 61 are larger, so as to reduce the number of lifting rods 51 used in the circulation process and avoid mechanical failures caused by the unstable lifting rod 51 hitting the second limit flange 611 when the lifting rod 51 is sent from one side of the first receiving groove to the other side during the sending process.

[0068] Further, the dried bean curd skin finishing machine further includes a peeling device 9 for peeling the sandwich cloth on both sides of the freshly made dried bean curd skin. The freshly made dried bean curd skin is clamped by the sandwich cloth on both sides, so the sandwich cloth on both sides can be peeled off by the peeling device 9. The working method of the peeling device 9 can refer to the Chinese patent document with the publication number CN206005754U applied by the inventor of this application. The dried bean curd skin processed by the peeling device 9 is directly conveyed and laid flat on the dried bean curd skin cooling conveyor belt 8 through its output belt 91.

[0069] The working process of the dried bean curd skin finishing machine provided by the present invention is as follows:

[0070] (1) After the freshly made dried bean curd skin is peeled off the sandwich cloth by the peeling device 9, the hot dried bean curd skin is output by the output belt 91 and laid flat on the dried bean curd skin cooling conveyor belt 8;

[0071] (2) When the dried bean curd skin on the dried bean curd skin cooling conveyor belt 8 is conveyed to the rear end of the dried bean curd skin cooling device 5 and falls, the upper bracing rod device 7 pushes the bracing rod upward, so that the dried bean curd skin falling on the dried bean curd skin cooling conveyor belt 8 is placed on the pushed-up bracing rod, and the bracing rod is finally pushed onto the cooling transmission chain 52;

[0072] (3) The dried bean curd skin placed on the bracing rod is cooled during the process of being conveyed along the cooling transmission chain 52. When the bracing rod with the dried bean curd skin moves to the rear end along the cooling transmission chain 52, it falls on the dried bean curd skin flattening mechanism 53. The dried bean curd skin flattening mechanism 53 drives the bracing rod to rotate to drop and flatten the dried bean curd skin on the upper surface of the dried bean curd skin conveyor belt 2;

[0073] (4) When the dried bean curd skin conveyor belt 2 conveys the dried bean curd skin to the front end and drops it, the mechanical gripper 32 on the dried bean curd skin stacking device 3 moves to the dried bean curd skin dropping position and opens the gripper claws 324. When the front end of the dried bean curd skin falls into the gripper claws 324, the mechanical gripper 32 continues to move forward, and the gripper claws 324 close to drive the dried bean curd skin to the dried bean curd skin receiving table 31 for stacking;

[0074] (5) Whenever a dried bean curd skin is stacked on the dried bean curd skin receiving table 31, the dried bean curd skin receiving table 31 can descend by a height corresponding to the thickness of one dried bean curd skin. In this way, the dried bean curd skin can always be stacked on the dried bean curd skin receiving table 31 until the dried bean curd skin receiving table 31 can no longer be lowered or the height of the stacked dried bean curd skin is appropriate. Then, the stacked dried bean curd skin on the dried bean curd skin receiving table 31 can be removed to continue stacking the next stack of dried bean curd skin.

[0075] Embodiment 2:

[0076] A dried bean curd skin finishing machine, please refer to Figures 1 to 7 .

[0077] The difference from Embodiment 1 is that in the dried bean curd sheet arranging machine provided by the embodiment of the present invention, the dried bean curd sheet flattening mechanism 53 drives the support rod 534 to swing by a certain angle through a driving mechanism, so that the hanging rod 51 rolls off the support rod 534.

[0078] Specifically, the driving mechanism includes a vertical rod 535 and a cylinder 536. The middle of the support rod 534 is hinged to the top end of the vertical rod 535, and the rear end is hinged to the top end of the cylinder 536. The vertical rod 535 and the cylinder 536 are installed on the frame where the dried bean curd sheet conveyor belt 2 is located. After the dried bean curd sheet 4 on the hanging rod 51 falls, operate the piston rod of the cylinder 536 to retract, which can pull the support rod 534 to swing clockwise by a certain angle, so that the hanging rod 51 falls off. The next hanging rod with a dried bean curd sheet can be placed on the support rod 534 to perform the flattening operation of the next dried bean curd sheet.

[0079] In addition, in other embodiments, a tangent roller can also be provided on the upper surface of the dried bean curd sheet conveyor belt 2 as the dried bean curd sheet flattening mechanism. One end of the dried bean curd sheet on the hanging rod falls on the dried bean curd sheet conveyor belt 2, and the rotation of the roller can pull the dried bean curd sheet off the hanging rod and spread it flat on the dried bean curd sheet conveyor belt 2.

[0080] Based on the above embodiments, the dried bean curd sheet arranging machine of the present invention can replace manual stacking of dried bean curd sheets, save labor, improve the stacking efficiency, and the dried bean curd sheets are directly stacked into a stack, which is convenient for handling.

[0081] The above has described the present invention in detail with reference to the drawings and embodiments; however, those skilled in the art can understand that without departing from the technical concept of the present invention, various specific parameters in the above embodiments can be changed to form multiple specific embodiments, which are all within the common change range of the present invention and will not be elaborated here one by one.
