This utility model also relates to soybean skin production equipment having the aforementioned soybean skin pressing and forming device. Background Technology
[0002] As a traditional soy product, the production process of bean curd sheets typically relies on manual labor or semi-automated equipment. In existing technology, concentrated soy milk is usually poured between two layers of bean curd sheet cloth to form a bean curd block. The bean curd block and its two sides (the bean curd sheets) are then repeatedly folded until a certain thickness is achieved, after which it is squeezed and dehydrated using a pressing device. After pressing, the bean curd sheets need to be manually peeled off the bean curd sheet cloth, or the bean curd sheets and bean curd sheet cloth need to be manually placed into a demolding device to separate the bean curd sheets from the two layers of bean curd sheet cloth.
[0003] In the existing bean curd skin production process, the pressing and demolding processes cannot be carried out continuously. Manual assistance is required between the pressing and demolding processes, resulting in low production efficiency of bean curd skin. Utility Model Content

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0006] A device includes a frame, an upper conveyor belt, a lower conveyor belt, a dehydration assembly, a pressing assembly, and a bean curd skin conveyor belt disposed on the frame;
[0007] The front end of the frame is equipped with a soy milk pouring device, which can coat the soy milk onto the lower conveyor belt to form soy milk cakes, and the rear end of the frame is equipped with a soy milk conveyor belt to carry soy milk skins.
[0008] Both the upper conveyor belt and the lower conveyor belt are made of bean curd sheet cloth, and the working sections of the lower conveyor belt and the upper conveyor belt are capable of clamping the bean curd sheets and conveying them to the bean curd sheet conveyor belt.
[0009] The dehydration component is located in front of the pressing component and includes two dewatering cylinders disposed on the upper and lower sides of the two working sections and used to squeeze the two working sections.
[0010] The dewatering cylinder includes a cage-shaped support frame rotatably mounted on the frame, and a cylinder wall surrounding the support frame, wherein the cylinder wall has a plurality of through holes arranged in an array.
[0011] The pressing assembly includes two pressure rollers rotatably mounted on the frame. The two pressure rollers are respectively located on the upper and lower sides of the two working sections and behind the dehydration assembly. The two pressure rollers can squeeze the soybean curd to form the soybean skin.
[0012] Furthermore, two roller brushes are rotatably mounted on the frame, with the two roller brushes located at the tail ends of the upper conveyor belt and the lower conveyor belt, respectively; the sweeping directions of the two roller brushes are opposite to the conveying directions of the upper conveyor belt and the lower conveyor belt, respectively, and the two roller brushes can peel off the bean skins attached to the upper conveyor belt or the lower conveyor belt.
[0013] Furthermore, the frame is equipped with a blower, which is configured as two separate blowers located on the upper and lower sides of the two working sections; the two blowers are located behind the pressing assembly, and the air outlets of the two blowers are oriented towards the two working sections.
[0014] Furthermore, the hair dryer includes a housing, a fan disposed within the housing, and a heating element disposed at the air outlet.
[0015] Furthermore, the pressing components are configured as a plurality of units spaced apart along the length of the frame, and the distance between two pressing rollers in the plurality of pressing components gradually decreases from the front end to the rear end of the frame.
[0016] Furthermore, in the pressing assembly, a lifting mechanism is provided between the upper pressure roller and the frame; the lifting mechanism includes two screws rotatably disposed on both sides of the frame and vertically arranged, two threaded sleeves disposed at both ends of the pressure roller shaft, and a worm gear rotatably disposed on the frame; the two threaded sleeves are screwed onto the two screws, and the bottom ends of the two screws are provided with worm wheels; the worm gear is located below the working section of the lower conveyor belt, and both ends of the worm gear mesh with the two worm wheels.
[0017] Furthermore, the frame is provided with a water collection tray, and the water collection tray is located below the lower conveyor belt working section.
[0018] Compared with the prior art, this utility model has the following advantages:
[0019] The bean curd sheet pressing and forming device of this utility model, by setting up an upper conveyor belt, a lower conveyor belt, and a pressing component, allows the bean curd sheets to be pressed and formed by the pressure rollers as the conveyor belts move, thus achieving continuous pressing of bean curd sheets. At the same time, by setting up a dehydration component, excess moisture in the bean curd sheets can be removed before pressing, thereby ensuring the production quality of bean curd sheets and improving the production efficiency of bean curd sheets.
[0020] In addition, two rotating brushes are installed on the frame to peel off the bean skins adhering to the upper or lower conveyor belt. Simultaneously, the brushes remove bean residue and other impurities stuck to the conveyor belt, preventing them from interfering with the separation of the bean skins from the conveyor belt and thus avoiding the bean skins sticking to it.

[0021] In addition, the blower includes a heating element at the air outlet, which increases the temperature of the airflow, improves the dehydration effect on the bean curd sheets, and accelerates the drying of the bean curd sheets and the conveyor belt, thereby further facilitating the shaping and separation of the bean curd sheets. The pressing components are configured as multiple units spaced apart along the length of the frame, which can gradually increase the extrusion pressure on the bean curd sheets, promoting the uniform and dense structure of the bean curd sheets and improving the production quality of the bean curd sheets.
[0022] Furthermore, in the pressing assembly, a lifting mechanism is provided between the upper pressure roller and the frame to facilitate adjustment of the bean skin thickness. Finally, a water collection tray is provided on the frame to collect water from the working section of the lower conveyor belt, preventing water released from the bean curd from splashing onto the return section of the lower conveyor belt and causing excessive moisture content in the belt.

[0042] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0043] Example 1
[0044] This embodiment relates to a bean curd skin pressing and forming device, the overall structure of which is as follows: Figure 1 , Figure 2 As shown, this embodiment includes a frame 1, an upper conveyor belt 2, a lower conveyor belt 3, a dehydration component, a pressing component, and a bean curd skin conveyor belt 105, all mounted on the frame 1.
[0045] The machine frame 1 has a soybean milk pouring device at its front end, which can coat soybean curd 7 onto the lower conveyor belt 3. The machine frame 1 also has a soybean curd skin conveyor belt 105 at its rear end, which carries soybean curd skin 8. Both the upper conveyor belt 2 and the lower conveyor belt 3 are made of soybean curd skin 8. The working sections of the lower conveyor belt 3 and the upper conveyor belt 2, i.e., the upper section of the lower conveyor belt 3 and the lower section of the upper conveyor belt 2, can clamp the soybean curd 7 and transport it to the soybean curd skin conveyor belt 105.
[0046] Meanwhile, the dehydration assembly is located in front of the pressing assembly and includes two dewatering cylinders 4, which are respectively disposed on the upper and lower sides of the two working sections and are used to squeeze the two working sections. The dewatering cylinder 4 includes a cage-shaped support frame 401 rotatably mounted on the frame 1, and a cylinder wall 402 surrounding the support frame 401, on which a plurality of through holes 403 are arranged in an array. The pressing assembly includes two pressure rollers 5 rotatably mounted on the frame 1. The two pressure rollers 5 are respectively disposed on the upper and lower sides of the two working sections and are located behind the dehydration assembly, and the two pressure rollers 5 can squeeze the bean curd 7 to form bean skin 8.
[0047] Understandably, if the soybean curd 7 is directly squeezed by the pressure roller 5, some of the water squeezed out of the soybean curd 7 will flow to the unsqueezed portion of the soybean curd 7, resulting in an excessively high moisture content in the unsqueezed portion. This portion of the soybean curd 7 is then prone to overflowing outside the two conveyor belts due to its high moisture content during subsequent pressing, or it may break due to compression, causing a decline in the quality of the soybean curd 7. However, by using the dewatering cylinder 4, which has multiple through holes 403 on its cylinder wall 402, the moisture in the soybean curd 7 can be discharged through the through holes 403 when the dewatering cylinder 4 squeezes the soybean curd 7, thus preventing the soybean curd 7 from having an excessively high moisture content.
[0048] As configured above, by setting up the upper conveyor belt 2, the lower conveyor belt 3, and the pressing component, the soybean curd 7 between the upper and lower conveyor belts 3 can be pressed and shaped by the pressure roller 5 as the conveyor belts move, achieving continuous pressing of the soybean skin 8. At the same time, by setting up the dehydration component, excess moisture in the soybean curd 7 can be removed before pressing, preventing the soybean curd 7 from having too high a moisture content and easily overflowing or breaking between the two conveyor belts, thereby ensuring the production quality of the soybean skin 8 and improving the production efficiency of the soybean skin 8.
[0049] Based on the above overview, specifically, the soy milk pouring device of this embodiment includes a soy milk tank 101 and a pouring hopper 102 mounted on a frame 1. The bottom of the soy milk tank 101 is provided with a discharge pipe 103, through which the concentrated soy milk in the soy milk tank 101 can be poured into the pouring hopper 102. The pouring hopper 102 can flow the soy milk to the working section of the lower conveyor belt 3 at a preset width, causing the soy milk to deposit on the lower conveyor belt 3 to form soybean curd 7.
[0050] Furthermore, in this embodiment, the bean curd sheet 8 forming the upper conveyor belt 2 and the lower conveyor belt 3 can be made of filter mesh cloth well-known to those skilled in the art for bean product production, such as cotton or linen mesh cloth or chemical fiber mesh cloth, to ensure that the bean curd sheet 8 cloth has good filtration performance. At the same time, the bean curd sheet conveyor belt 105 located on the frame 1 can transport the formed bean curd sheet 8 to other workstations.
[0051] To prevent the pressed bean curd sheets 8 from sticking to the working sections of the upper and lower conveyor belts 3, two roller brushes 106 are rotatably mounted on the frame 1 in this embodiment. The two roller brushes 106 are located at the tail ends of the upper conveyor belt 2 and the lower conveyor belt 3, respectively. The sweeping directions of the two roller brushes 106 are opposite to the conveying directions of the upper conveyor belt 2 and the lower conveyor belt 3, respectively. The two roller brushes 106 can peel off the bean curd sheets 8 attached to the upper conveyor belt 2 or the lower conveyor belt 3. With the two roller brushes 106 positioned so that their sweeping directions are opposite to the conveying directions of the two conveyor belts, the roller brushes 106 can peel off the bean curd sheets 8 from the conveyor belts. The peeled bean curd sheets 7 can be supported by the roller brushes 106 located at the tail end of the lower conveyor belt 3 and conveyed to the bean curd sheet conveyor belt 105. At the same time, the roller brushes 106 can peel off the bean curd residue and other impurities adhering to the conveyor belt, avoiding affecting the separation of the conveyor belt and the bean curd sheets 8, thereby preventing the bean curd sheets 8 from sticking to the conveyor belt.
[0052] To further facilitate the separation of the bean curd sheet 8 from the conveyor belt, the frame 1 in this embodiment is equipped with a blower 6, which is configured as two separate blowers located on the upper and lower sides of the two working sections. The two blowers 6 are located behind the pressing assembly, and their air outlets face the two working sections. By configuring the blowers 6, air can be blown onto the pressed bean curd sheet 8 and the two working sections, using the airflow to remove moisture from the bean curd sheet 8 and the two working sections, thus facilitating the shaping of the bean curd sheet 8 and its separation from the conveyor belt.
[0053] Specifically, the blower 6 includes a housing 601, a fan 602 disposed within the housing 601, and a heating element 603 disposed at the air outlet. By setting the heating element 603, the temperature of the airflow blown out by the blower 6 can be increased, thereby improving the dehydration effect on the bean curd skin 8, accelerating the drying of the bean curd skin 8 and the conveyor belt, and further facilitating the shaping and separation of the bean curd skin 8.
[0054] In practical implementation, the heating element in this embodiment can be a conventional heating element such as an electric heating tube or an electric heating wire, as long as it can increase the airflow temperature.
[0055] As a specific implementation, this embodiment configures multiple pressing components spaced apart along the length of the frame 1, with the distance between the two pressure rollers 5 in each pressing component gradually decreasing from the front end to the rear end of the frame 1. By setting multiple pressing components and gradually decreasing the distance between the pressure rollers 5 in each pressing component, progressive pressing of the soybean curd 7 can be achieved. During the process of the soybean curd 7 passing through each pressing component, it undergoes a continuous pressing process of loosening, initial compaction, and dense shaping. During this process, the thickness of the soybean curd 7 gradually decreases, ultimately pressing it to a preset thickness to form soybean skin 8. This allows for a gradual increase in the extrusion pressure on the soybean curd 7, promoting the uniform and dense structure of the soybean curd 7 and improving the production quality of the soybean skin 8.
[0056] Specifically, in order to facilitate the adjustment of the thickness of the bean curd skin 8, a lifting mechanism is provided between the upper pressure roller 5 and the frame 1 in the pressing assembly of this embodiment.
[0057] Among them, such as Figure 3 As shown, the lifting mechanism includes two screws 501 rotatably mounted on both sides of the frame 1 and vertically arranged, two threaded sleeves 502 located at both ends of the shaft of the pressure roller 5, and a worm gear 503 rotatably mounted on the frame 1. The two threaded sleeves 502 are screwed onto the two screws 501, and the bottom ends of the two screws 501 are provided with worm wheels 5011. The worm gear 503 is located below the working section of the lower conveyor belt 3, and both ends of the worm gear 503 mesh with the two worm wheels 5011. When the worm gear 503 is driven to rotate, it can drive the two screws 501 to rotate synchronously, thereby causing the two threaded sleeves 502 to move along the length of the screws 501, changing the distance between the two pressure rollers 5, and thus changing the thickness of the bean curd skin 8. In a specific implementation, one end of the worm gear 503 in this embodiment is provided with a handwheel 504, which can drive the worm gear 503 to rotate by rotating the handwheel 504. In addition, in the worm 503 of this embodiment, only the two ends of the worm 503 have worm structures, and the screw 501 only has a thread structure at its top part, so as to reduce the processing cost of the screw 501 and the worm 503.
[0058] Finally, in this embodiment, a water collection tray 104 is provided on the frame 1, and the water collection tray 104 is located below the working section of the lower conveyor belt 3. By setting up the water collection tray 104, water from the working section of the lower conveyor belt 3 can be collected, preventing water that has escaped from the bean curd 7 from being poured onto the return section of the lower conveyor belt 3, which would cause the moisture content of the lower conveyor belt 3 to be too high and affect the coating of the bean curd 7 on the lower conveyor belt 3, thus ensuring the production quality of the bean skin 8.
[0059] In summary, the bean curd sheet pressing and forming device of this embodiment, by setting up an upper conveyor belt 2, a lower conveyor belt 3, and a pressing component, allows the bean curd sheet 7 to be pressed and formed by the pressure roller 5 as it moves along the conveyor belt, thus achieving continuous pressing of the bean curd sheet 8. At the same time, by setting up a dehydration component, excess moisture in the bean curd sheet 7 can be removed before pressing, thereby ensuring the production quality of the bean curd sheet 8 and improving the production efficiency of the bean curd sheet 8.
[0060] Example 2
[0061] This embodiment relates to a bean curd skin production equipment, which has a bean curd skin pressing and forming device as described in Embodiment 1.
[0062] The bean curd sheet production equipment of this embodiment, through the setting of the bean curd sheet pressing and molding device, can realize the continuous pressing and molding of bean curd sheet 8, and through the setting of the dehydration component, can remove excess water from bean curd sheet 7 before pressing, thereby ensuring the production quality of bean curd sheet 8 and improving the production efficiency of bean curd sheet 8.
[0063] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
