Description

Technical Field

[0001] This invention relates to the field of packing device technology, and more specifically, to a packing device for making tofu with a coating. Background Technology

[0002] In the production of tofu with a crisp coating, semi-fluid tofu raw materials need to be accurately and quickly filled into the shaping mold. Currently, the commonly used filling methods in the industry either rely on manual pouring with a scoop, resulting in low efficiency, or use simple hoppers with valve control, which, while achieving a certain degree of mechanization, still have significant shortcomings. During the filling process, due to the viscous texture of the tofu raw materials, some tofu tends to adhere to the inner wall of the hopper and gradually accumulate when poured into the shaping mold below. This residue not only wastes raw materials but also dries and hardens over time, affecting the accuracy of subsequent filling and may even detach and mix into the new product, affecting the consistency of product quality. To address this, this application designs a filling device for tofu with a crisp coating, which can achieve efficient and continuous filling and effectively avoid raw material residue inside the equipment. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a filling device for tofu with a coating, which solves the problem that some tofu remains on the inner wall of the device during the filling process, leading to waste of filling material or a decline in quality.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A filling device for tofu includes a conveyor belt with several protrusions on both sides of the middle section of the conveyor belt. A filling assembly for filling tofu is fixedly installed on the upper side of the protrusions. Several storage tanks are provided on one side of the conveyor belt. A conveying pump for replenishing tofu material is provided at the bottom of the storage tanks. A solenoid valve for controlling the filling is provided at the lower end of the filling assembly.

[0005] Preferably, the packing assembly includes a plurality of columns, which are fixedly installed on the upper end of corresponding protrusions. Connecting blocks are fixedly installed on the upper ends of the plurality of columns, and receiving frames are fixedly installed between the plurality of connecting blocks. A discharge port is provided at the bottom of the receiving frame, and the lower end of the discharge port is fixedly connected to a solenoid valve.

[0006] Preferably, the feed end of the conveying pump is connected to the lower end of the storage tank through a receiving pipe, the discharge end of the conveying pump is fixedly installed with a conveying pipe, one end of the conveying pipe is fixedly installed with a discharge pipe, and the two discharge pipes are respectively located inside the receiving frame on both sides.

[0007] Preferably, a vertical groove is provided on the upper side of the receiving frame, a material guide groove is provided on the lower side of the receiving frame, and a plane bearing is fixedly installed on the upper surface of the receiving frame.

[0008] Preferably, an annular slide is slidably mounted on the upper side of the plane bearing, a driven bracket is fixedly mounted on the inner side of the annular slide, a fixed column is provided on the lower side of the driven bracket, a vertical scraper is provided on one side of the fixed column, and a guide scraper is provided on the lower side of the fixed column.

[0009] Preferably, the driven card holder has a movable through hole inside, and a movable connecting rod is fixedly installed at the upper end of the fixed column. The movable connecting rod is limited and movable inside the movable through hole.

[0010] Preferably, a support spring is fixedly installed between the movable connecting rod body and the bottom of the driven bracket.

[0011] Preferably, the vertical scraper is close to the surface of the vertical groove, the guide scraper is close to the surface of the guide groove, and the guide scraper body is inclined.

[0012] Preferably, a mating gear ring is fixedly installed on the outer side of the annular slide, an extension platform is fixedly installed on the outer side of the receiving frame, a drive motor is fixedly installed on the upper end of the extension platform, a drive gear is fixedly installed on the output end of the drive motor, and the drive gear meshes with the mating gear ring.

[0013] Preferably, a fixed base is fixedly installed on one side of the conveyor belt, and a conveyor motor is fixedly installed on the upper end of the fixed base. The output end of the conveyor motor is connected to the drive shaft of the conveyor belt through a gearbox.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The filling assembly incorporates guide scrapers and vertical scrapers driven by a motor inside the receiving frame. These components continuously scrape the inner wall of the frame and the inclined surface of the guide channel during the filling process. The combined design of the vertical scraper and the inclined guide scraper ensures that viscous tofu raw materials are effectively separated and smoothly guided to the discharge port, fundamentally solving the problems of raw material adhesion and accumulation. Furthermore, the continuous scraping process by the filling assembly reduces residual tofu, thus achieving an active self-cleaning mechanism to prevent tofu residue from fermenting or breeding bacteria inside the equipment.

[0015] 2. The conveying pump can quickly replenish the raw material in the storage tank to the receiving frame during the gap between the completion of one mold filling and the arrival of the next mold, ensuring that the filling action can be carried out immediately. This parallel design of filling and replenishment allows the equipment to match the conveyor belt speed, achieving uninterrupted continuous filling and significantly improving overall production efficiency.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 8 As shown, a filling device for tofu includes a conveyor belt 1, several protrusions 3 are provided on both sides of the middle of the conveyor belt 1, a filling component 6 for filling tofu is fixedly installed on the upper side of the protrusions 3, several storage tanks 4 are provided on one side of the conveyor belt 1, a conveying pump 5 for replenishing tofu material is provided at the bottom of the storage tank 4, and a solenoid valve 7 for controlling the filling is provided at the lower end of the filling component 6.

[0020] Semi-finished tofu can be stored in storage tank 4 to ensure the current storage quality of tofu and reduce external interference; By starting the delivery pump 5, the tofu inside the storage tank 4 can be extracted as needed and delivered to the packing assembly 6, thereby quickly replenishing the required packing to meet the needs of continuous packing. This application uses multiple delivery pumps 5, which can be used separately to avoid the temperature rise of a single delivery pump 5 due to excessive use, which would affect the extraction efficiency. The filling operation of the filling assembly 6 can be controlled by the solenoid valve 7. The mold for forming tofu can be conveyed by the conveyor belt 1. When one of the molds moves under the filling assembly 6, the solenoid valve 7 is opened to quickly discharge the tofu pre-stored inside the filling assembly 6 downwards. After the filling is completed, the solenoid valve 7 is closed, so that the filling assembly 6 stops filling downwards.

[0021] In this embodiment, the packing assembly 6 includes a plurality of columns 601, which are fixedly installed on the upper end of the corresponding boss 3. A connecting block 602 is fixedly installed on the upper end of the plurality of columns 601, and a receiving frame 603 is fixedly installed between the plurality of connecting blocks 602. A discharge port 6031 is provided at the bottom of the receiving frame 603, and the lower end of the discharge port 6031 is fixedly connected to the solenoid valve 7.

[0022] The receiving frame 603 can be positioned above the middle of the conveyor belt 1 by the support of the column 601, so that the mold conveyed inside the conveyor belt 1 can pass under the receiving frame 603 and receive the tofu material pre-stored inside the receiving frame 603. The height of the column 601 can be changed according to the size of the forming mold.

[0023] In the specific setup, the feed end of the conveying pump 5 is connected to the lower end of the storage tank 4 through the receiving pipe 501, the discharge end of the conveying pump 5 is fixedly installed with the conveying pipe 502, one end of the conveying pipe 502 is fixedly installed with the discharge pipe 503, and the two discharge pipes 503 are located on both sides inside the receiving frame 603 respectively.

[0024] The lower end of the storage tank 4 is connected to the conveying pump 5 through the receiving pipe 501. When the conveying pump 5 is started, the tofu is drawn out from the storage tank 4 under the action of the conveying pump 5. The tofu is then conveyed to the discharge pipe 503 through the conveying pipe 502. Finally, the tofu is accurately discharged into the receiving frame 603 through the discharge pipe 503, thereby realizing the rapid replenishment of tofu material. Multiple conveying pumps 5 can also be started at the same time as needed to increase the speed of tofu replenishment. The receiving frame 603 can pre-store tofu to meet the efficiency requirements of continuous tofu filling.

[0025] In this application, a vertical groove 6033 is provided on the upper side of the receiving frame 603, and a guide groove 6032 is provided on the lower side of the receiving frame 603. A plane bearing 6034 is fixedly installed on the upper surface of the receiving frame 603. The tofu inside the receiving frame 603 can be guided downward and discharged through the guide groove 6032, thereby realizing the tofu falling into the filling material by itself.

[0026] In the specific configuration, an annular slide 605 is slidably mounted on the upper side of the plane bearing 6034, a driven bracket 606 is fixedly mounted on the inner side of the annular slide 605, a fixed column 6082 is provided on the lower side of the driven bracket 606, a vertical scraper 6083 is provided on one side of the fixed column 6082, and a guide scraper 607 is provided on the lower side of the fixed column 6082.

[0027] The vertical scraper 6083 can scrape the inner wall of the vertical trough 6033 to prevent some tofu from remaining on the inner wall of the vertical trough 6033 when the tofu falls on its own. Both the vertical scraper 6083 and the guide scraper 607 are made of flexible materials. The guide scraper 607 can push the tofu at the bottom of the guide trough 6032, and its inclined setting can guide the passing tofu, thereby increasing the tofu filling speed and meeting the efficiency requirements of automatic filling.

[0028] It should be noted that the driven card holder 606 has a movable through hole 6061 inside, and a movable connecting rod 608 is fixedly installed on the upper end of the fixed post 6082. The movable connecting rod 608 is limited and movable inside the movable through hole 6061.

[0029] A support spring 6081 is fixedly installed between the movable connecting rod 608 and the bottom of the driven bracket 606.

[0030] The movable through hole 6061 can limit the lifting and lowering movement of the movable link 608 to ensure its stable lifting and lowering. The support spring 6081 is set between the body of the movable link 608 and the bottom of the driven bracket 606, so that the body of the movable link 608 can make a certain range of lifting and lowering changes, so that the guide scraper 607 reduces the resistance during the initial movement and further improves its service life.

[0031] In this application, the vertical scraper 6083 is close to the surface of the vertical groove 6033, the guide scraper 607 is close to the surface of the guide groove 6032, and the guide scraper 607 is inclined.

[0032] In this embodiment, a mating gear ring 6051 is fixedly installed on the outer side of the annular slide 605, an extension platform 604 is fixedly installed on the outer side of the receiving frame 603, a drive motor 6041 is fixedly installed on the upper end of the extension platform 604, a drive gear 6042 is fixedly installed on the output end of the drive motor 6041, and the drive gear 6042 meshes with the mating gear ring 6051.

[0033] The drive motor 6041 is started to drive the drive gear 6042 to rotate. Under the rotation of the drive gear 6042, it meshes with the gear ring 6051 for transmission. The plane bearing 6034 and the annular slide 605 are in sliding fit, so as to realize the continuous rotation of the annular slide 605. The annular slide 605 is fixedly connected to the driven bracket 606, so that the vertical scraper 6083 and the guide scraper 607 both rotate continuously. This realizes the comprehensive guidance of tofu material to the receiving frame 603 and the comprehensive cleaning of residual tofu material adhering to the inner wall of the receiving frame 603. The filling assembly 6 not only realizes efficient filling operation, but also reduces the residue of tofu material during the filling process, reduces material waste, and accurately controls the filling amount.

[0034] In this application, a fixed base 2 is fixedly installed on one side of the conveyor belt 1, and a conveyor motor 201 is fixedly installed on the upper end of the fixed base 2. The output end of the conveyor motor 201 is connected to the drive shaft of the conveyor belt 1 through a gearbox. The conveyor motor 201 can drive the drive shaft of the conveyor belt 1 to rotate, thereby realizing the operation of the conveyor belt 1 and continuously conveying the mold.

[0035] The working principle of this type of filling device for tofu with a coating: In use, the molds for shaping tofu are first placed on the conveyor belt 1 in sequence. Then, the conveyor motor 201 is started to make the conveyor belt 1 transport the molds. When one of the molds moves to the bottom of the filling assembly 6, the solenoid valve 7 is opened and the drive motor 6041 is started at the same time. The drive gear 6042 meshes with the gear ring 6051 to make the annular slide 605 move, which drives the vertical scraper 6083 and the guide scraper 607 to rotate inside the receiving frame 603, so that the tofu inside the receiving frame 603 falls quickly into the mold, thus realizing the rapid filling operation. After the filling is completed, the solenoid valve 7 is turned off, and then the delivery pump 5 is started to transport the tofu inside the storage tank 4 to the receiving frame 603. This allows the receiving frame 603 to extract the tofu for replenishing the filling before the next mold arrives, thus achieving efficient filling operation.

[0036] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
