Description

Technical Field

[0001] This utility model relates to the field of soybean product production technology, and in particular to a tofu skin production system. Background Technology

[0002] The existing tofu production system includes equipment such as a pouring machine, a press, and a frame return system. The production process is roughly as follows: the pouring machine pours the tofu curd into a frame, which is then sent to the press for pre-pressing and main pressing via the frame return system. Next, it is sent to the cloth-peeling station to separate the cloth, and the finished product is sent to subsequent processes. Finally, the frame is returned to the starting position of the pouring machine, completing one production cycle.

[0003] The applicant has discovered that the prior art has at least the following technical problems:

[0004] Traditional folding methods often involve frame movement or arched pendulum conveyor swinging, but both can lead to uneven distribution of the fabric within the frame, resulting in unstable quality of the sheets and limited production output.

[0005] Specifically, if a frame-based folding method is used, the frame generates inertia during the folding process. The product then bounces and bumps against the frame, resulting in a high breakage rate on both sides and a decrease in product quality. To reduce inertia and increase the yield, the production speed must be reduced, but this limits output.

[0006] If an arched pendulum conveyor is used for folding, the mold frame does not move, and the arched pendulum conveyor drives the wrapping cloth forward to fold it into the mold frame to complete the pouring. Since the swing arm of the arched pendulum conveyor has a swing angle of 87 degrees to 175 degrees, changes in the swing arm angle can cause the tofu pudding to flow directly downwards at its highest point, damaging the product and affecting both output and quality. For example, application number CN202420052739.6 discloses a conveying mechanism and a tofu skin production system.

[0007] In view of the above, this utility model is hereby proposed. Utility Model Content

The lifting base plate is connected to the frame via the scissor assembly.

[0021] This invention effectively avoids the technical problems of uneven fabric distribution, unstable quality, and limited output caused by the design defects of the folding method in existing thousand-sheet production systems. This invention provides a thousand-sheet production system, including a frame, and a folding mechanism, a conveying mechanism, and a frame return mechanism mounted on the frame. The frame is provided with an initial position, a folding position, a pre-pressing position, a main pressing position, and a peeling position. The conveying mechanism drives the frame to sequentially pass through the initial position, folding position, pre-pressing position, main pressing position, and peeling position. The frame return mechanism connects the initial position and the peeling position, and is used to drive the frame from the peeling position to the initial position, completing the cyclic use of the frame.

The feeding end of the first transmission component corresponds to the unloading end of the casting machine, and the unloading end of the first transmission component corresponds to the second transmission component, and is connected to the second transmission component through a linkage component. The pushing component drives the unloading end of the first transmission component to move horizontally reciprocally, causing the second transmission component to move horizontally reciprocally at the folding position, so that the fabric is folded within the frame. This invention utilizes the synergistic action of a first transmission component, a second transmission component, and a pushing component. The first transmission component receives the product, and through the driving force of the pushing component, it cooperates with the second transmission component to uniformly fold the product at the folding position. Furthermore, as the reciprocating speed of the first transmission component increases, while the transmission speed of the second transmission component remains constant, the length of the product increases. The faster the transmission speed of the second transmission component, the shorter the product length. By adjusting the speeds of the first and second transmission components, the length of the product can be controlled, thereby enabling the production system to adapt to diverse production needs and improving production flexibility and efficiency.

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0039] like Figures 1-5As shown, this utility model provides a tofu sheet production system, including a frame 1, and a folding mechanism, a conveying mechanism, and a return frame mechanism 8 disposed on the frame 1. The frame 1 is provided with an initial position 101, a folding position 102, a pre-pressing position 103, a main pressing position 104, and a peeling position 105. The conveying mechanism drives the frame 11 to pass through the initial position 101, the folding position 102, the pre-pressing position 103, the main pressing position 104, and the peeling position 105 in sequence. The return frame mechanism 8 connects the initial position 101 and the peeling position 105 and is used to drive the frame 11 to move from the peeling position 105 to the initial position 101 to complete the cyclic use of the frame 11.

[0040] The folding mechanism includes a first transmission component 2, a second transmission component 3, and a pushing component 5. The feeding end of the first transmission component 2 is correspondingly set to the unloading end of the casting machine, and the unloading end of the first transmission component 2 is correspondingly set to the second transmission component 3. The first transmission component 2 is connected to the second transmission component 3 through a linkage component 4. The pushing component 5 drives the unloading end of the first transmission component 2 to move horizontally back and forth, thereby driving the second transmission component 3 to move horizontally back and forth at the folding position 102, so that the fabric is folded within the frame 11.

[0041] Through the coordinated action of the first transmission component 2, the second transmission component 3, and the pushing component 5, the first transmission component 2 receives the product, and, driven by the pushing component 5, cooperates with the second transmission component 3 to complete the uniform folding of the product at the folding position 102. Furthermore, as the reciprocating speed of the first transmission component 2 increases, while the transmission speed of the second transmission component 3 remains constant, the length of the product increases. The faster the transmission speed of the second transmission component 3, the shorter the product length. By adjusting the speeds of the first transmission component 2 and the second transmission component 3, the length of the product can be controlled, thereby enabling the production system to adapt to diverse production needs and improving production flexibility and efficiency.

[0042] Furthermore, a support plate 107 is provided on the frame 1 at the positions corresponding to the pre-pressing position 103 and the main pressing position 104 to support the frame 11 and the product. A conveying guide plate 108 is provided on at least one side of the positions corresponding to the initial position 101, folding position 102, pre-pressing position 103, main pressing position 104, and peeling position 105 to guide the frame 11 along a preset path. A return frame guide plate 109 is provided on the return frame section 106 between the peeling position 105 and the initial position 101 on the frame 1 to guide the frame 11 along a preset path from the peeling position 105 to the initial position 101, realizing the automatic recycling of the frame 11 and improving the continuity and cyclicality of the thousand-sheet production process.

[0043] As an optional implementation, such as Figure 1 , Figure 2 , Figure 3As shown, the first transmission component 2 includes a first active roller 201, a first driven roller 202, a first conveying part 203, a first driving part 204, and a first mounting base 205. The first conveying part 203 is mounted on the first active roller 201 and the first driven roller 202. The first active roller 201 is located close to the casting machine and is connected to the first driving part 204. The first driven roller 202 is mounted on the first mounting base 205. The first mounting base 205 is connected to the pushing component 5 and is slidably connected to the frame 1 through the first guiding component.

[0044] Furthermore, the first transmission unit includes a conveyor belt. The first transmission component 2 receives tofu curd from the casting machine and forms a product consisting of an upper layer of cloth, tofu curd, and a lower layer of cloth, arranged from top to bottom, at its feed end. The specific formation process of the upper layer of cloth, tofu curd, and lower layer of cloth is prior art and will not be described in detail here.

[0045] The first drive unit 204 provides power to the first active roller 201, thereby driving the first conveying unit 203 to transport the product to the second transmission unit.

[0046] The first guide assembly includes a first guide groove 1010 and a first guide slider 206 that slides in cooperation with the first guide groove 1010. The first guide groove 1010 is disposed on the frame 1, and the first guide slider 206 is disposed on the bottom surface of the first mounting base 205. Through the sliding cooperation between the first guide slider 206 and the first guide groove 1010, the first mounting base 205 can move along a preset path during reciprocating movement, thereby improving the reliability and stability of movement.

[0047] A tension adjusting roller group 207 is provided at the lower part of the first transmission unit for adjusting the tension of the first transmission unit. The specific number, specifications and layout of the adjusting rollers in the tension adjusting roller group 207 can be designed according to the usage requirements.

[0048] As an optional implementation, such as Figure 1 , Figure 2 , Figure 3 As shown, the second transmission assembly 3 includes a second active roller 301, a second driven roller 302, a second transmission section 303, a second drive section 304, and a second mounting base 305. The second transmission section 303 is mounted on the second active roller 301 and the second driven roller 302. The second drive section 304 is connected to the second active roller 301 in a transmission manner. The second active roller 301 and the second driven roller 302 are mounted on the second mounting base 305. The second mounting base 305 is slidably connected to the frame 1 through a second guide assembly.

[0049] Furthermore, the second conveying unit 303 has a conveying direction opposite to that of the first conveying unit 203. The second driving unit 304 provides power to the second drive roller 301, thereby driving the second conveying unit 303 to transport the product into the mold frame 11.

[0050] The second guide assembly includes a second guide groove 306 and a second guide slider 1011 that slides with the second guide groove 306. The second guide groove 306 is disposed on the bottom surface of the second mounting base 305, and the second guide slider 1011 is disposed on the frame 1. Through the sliding engagement between the second guide slider 1011 and the second guide groove 306, the second mounting base 305 can move along a preset path during reciprocating movement, thereby improving the reliability and stability of movement.

[0051] As an optional implementation, such as Figure 1 , Figure 2 , Figure 3 As shown, the linkage assembly 4 includes a first sprocket, a first chain 401, a second sprocket 402, and a second chain 403. The first sprocket is connected to the first driven roller shaft 202 and meshes with the first chain 401. One end of the first chain 401 is connected to the frame 1, and the other end is connected to one end of the second mounting base 305. The second sprocket 402 is connected to the first driven roller shaft 202 and meshes with the second chain 403. One end of the second chain 403 is connected to the frame 1, and the other end is connected to the other end of the second mounting base 305.

[0052] Furthermore, the driving component 5 drives the first mounting base 205 to move the first driven roller 202 reciprocally in the horizontal direction. The specific structure of the driving component 5 adopts existing technology; as long as it can achieve the aforementioned functions, it is acceptable, and will not be elaborated upon here.

[0053] The drive component 5 drives the first driven roller 202 to move, which in turn drives the first sprocket and the second sprocket 402 to move synchronously, thereby driving the second mounting base 305 and the second conveyor 303 to move in the same direction.

[0054] Through the transmission of the first sprocket and the first chain 401, as well as the second sprocket 402 and the second chain 403, the movement of the first driven roller shaft 202 is transmitted to the second mounting base 305, thereby realizing the synchronous movement of the first transmission component 2 and the second transmission component 3 and improving the stability and reliability of the transmission.

[0055] As an optional implementation, such as Figure 5As shown, it also includes a lifting mechanism 7, which is located at the folding position 102. The lifting mechanism 7 includes a first push rod 701, a scissor assembly 702 and a lifting base plate 703. The lifting base plate 703 is connected to the frame 1 through the scissor assembly 702. One end of the first push rod 701 is rotatably connected to the frame 1 and the other end is connected to the lifting base plate 703, which is used to drive the lifting base plate 703 to perform lifting and lowering actions within the frame 11.

[0056] Furthermore, the lifting mechanism 7 is located below the folding position 102.

[0057] When the second conveying unit 303 conveys the product into the mold frame 11, the first push rod 701 drives the lifting base plate 703 to perform lifting and lowering actions within the mold frame 11 to assist in folding the product. The first push rod 701 includes, but is not limited to, electric push rods, pneumatic push rods, and hydraulic push rods.

[0058] As an optional implementation, the unloading end of the second conveying unit 303 is provided with a height detection component to detect the height of the products stacked within the frame 11, thereby avoiding problems caused by excessive stacking.

[0059] As an optional implementation, such as Figure 4 As shown, the frame return mechanism 8 includes a third conveying part 801 and a third driving part 802. The third conveying part 801 is a closed structure and connects the initial position 101 and the peeling position 105. A driving member is provided on the third conveying part 801. The third driving part 802 drives the third conveying part 801 to move, thereby moving the frame 11.

[0060] Furthermore, the return frame guide plate 109 slides with the molded frame 11. The function of the return frame guide plate 109 is to support the molded frame 11 and to guide the molded frame 11 when the third transmission part 801 drives the molded frame 11 from the peeling position 105 to the initial position 101, so that the molded frame 11 moves from the peeling position 105 to the initial position 101 along a preset path under the action of the driving member.

[0061] The upper surface of the third conveying section 801 is lower than or flush with the bottom surface of the return frame guide plate 109, and the return frame guide plate 109 has an opening 1091 for the third conveying section 801 and the driving member to pass through. This arrangement is for the convenience of the layout of the third conveying section 801. Since the movement path of the mold frame 11 from the peeling position 105 to the initial position 101 is U-shaped, in the U-shaped movement path, the driving member abuts against different side plates of the mold frame 11 through the opening 1091, realizing the turning and continued movement of the mold frame 11. Specifically, after the mold frame 11 completes the upper layer wrapping, tofu sheet and lower layer wrapping operations at the driving peeling position 105, the driving member abuts against the long side plate of the mold frame 11, driving it to move from the peeling position 105 to the entrance of the return frame section 106. At this time, the mold frame 11 is intercepted by the return frame guide plate 109 and temporarily stops. The continuous movement of the third conveyor causes the driving component to pass through the opening 1091 and abut against the short side plate of the mold frame 11, driving the mold frame 11 to move towards the exit of the return frame section 106. The mold frame 11 remains stationary until it is intercepted by the return frame guide plate 109 at the exit of the return frame section 106. The continuous movement of the third conveyor causes the driving component to pass through the opening 1091 and abut against the long side plate of the mold frame 11, driving it to move from the exit of the return frame section 106 to the initial position 101.

[0062] In existing technologies, multiple sensors need to be installed along the moving path of the mold frame 11 to detect its specific position in order to achieve the cycle of the mold frame 11. Due to the humid operating environment, the failure rate is high and the overall cost is high. This utility model achieves automatic cyclic use of the mold frame 11 by pre-setting the distance between the peeling position 105 and the initial position 101 through the control module, which simplifies the structure, reduces costs and failure rate, and improves the continuity and cyclicality of the production process.

[0063] As an optional implementation, the third transmission unit includes a belt or chain plate, and the third drive unit includes a hydraulic motor, an electric motor, or a geared motor.

[0064] As an optional implementation, such as Figure 1 , Figure 4 As shown, it also includes a pre-press 9 and a main press 10. The pre-press 9 is located above the pre-press position 103, and the main press 10 is located above the main press position 104, for pressing the product in the frame 11.

[0065] Furthermore, the bottom plate of the mold frame 11 has receiving grooves at its four corners for installing spring balls as in the prior art. When the mold frame 11 slides on the conveying guide plate 108 and the return frame guide plate 109, the spring balls reduce the direct contact area between the mold frame 11 and the conveying guide plate 108 and the return frame guide plate 109, reducing friction, wear, and extending service life. When the pre-press 9 and the main press 10 apply pressure to the mold frame, the spring balls retract into the mold frame 11 in response to the pressure. Specifically, the lower end face of the spring balls remains flush with the bottom surface of the mold frame 11, ensuring the uniformity of the pressure applied to the product by the pre-press 9 and the main press 10, and avoiding any uneven pressing effect due to the presence of the spring balls.

[0066] It should be noted that the specific structures of the pre-press 9 and the main press 10 adopt existing technology. As long as they can remove excess moisture from the product within the pressing frame 11, they are acceptable. No further details will be provided here.

[0067] As an optional implementation, the conveying mechanism includes a second push rod 6.

[0068] The telescopic end of the second push rod 6 abuts against the side plate of the frame 11, driving the frame 11 to move between the initial position 101, the folding position 102, the pre-pressing position 103, the main pressing position 104, and the peeling position 105. At each station, the frame 11 remains stationary for a period of time to complete the corresponding operation, thus completing the thousand-sheet production process. Specifically, when the frame 11 is stationary at the folding position 102, the first transmission component 2 receives the product and, through the drive of the push component 5 and in cooperation with the second transmission component 3, completes the uniform folding of the product within the frame 11. The second push rod 6 includes, but is not limited to, electric push rods, pneumatic push rods, and hydraulic push rods.

[0069] When frame 11 stops at pre-compression position 103, pre-compression machine 9 presses the product inside frame 11 to remove some moisture.

[0070] When the mold frame 11 stops at the main pressure position 104, the main press 10 further presses the product inside the mold frame 11 to remove more moisture.

[0071] When the frame 11 stops at the peeling position 105, the separation of the upper wrapping cloth, the tofu skin and the lower wrapping cloth is completed.
