Description

Technical Field:

[0001] The present invention relates to a machine for automatically rolling fillings into bean curd sheets, belonging to the technical field of food processing devices. Background Art:

[0002] With the development of the economy and the progress of society, the products of soy products have been aging day by day. In recent years, major soy product manufacturers have been intensifying their research and development of new products to meet the changing needs of consumers. The sandwich bean rolls developed by our company have come into being. The sandwich bean rolls utilize the flexible characteristic of traditional bean curd sheets that can be rolled into cylinders. Before rolling, various edible food fillings are added to make bean rolls such as chicken bean rolls, duck bean rolls, mushroom bean rolls, sprout bean rolls, bamboo shoot bean rolls, and so on.

[0003] In the current existing technologies, the bean rolls made by each manufacturer are all manually rolled, which is time-consuming and laborious, and the working cycle is very long. In the production process, it is also very easy to occur the phenomena of deterioration, putrefaction and rancidity, resulting in product scrapping. Currently, there are two forms of making bean rolls:

[0004] 1. Completely handmade: A large bean curd sheet is cut into small square bean curd sheets with a size of 100mm * 100mm. Manually scoop a small ladle of prepared filling, about 15g, and place it on the small bean curd sheet. Use the fingers of both hands to fold two corners of the bean curd sheet and hold them, and then continuously roll forward with the thumb to complete the rolling of one bean roll. One worker can produce 35 catties of bean rolls per hour. Calculated based on a 10-hour shift, it is 350 catties / shift. The characteristic is that each one is hand-rolled individually. It is easy to breed bacteria. The working time is long, and fermentation and souring affect the taste.

[0005] 2. In the Hubei region, there is a traditional habit of using a "manual cigarette rolling machine" to roll bean rolls. However, relatively speaking, the efficiency of rolling bean rolls with the manual cigarette rolling machine is about 1.2 times higher than that of completely handmade rolling, that is, 420 catties / shift. The cigarette rolling machine also requires manual filling. When pouring the filling into the filling tray, it needs to be manually leveled. The filling is scraped into the filling groove by using a quantitative scraping knife, and then a whole piece of bean curd sheet with a length of 300mm * a width of 120mm is manually placed. The bean curd sheet is rolled by pulling with a piercing rod to drive the wrapping cloth. After one roll is cut, there are 3 - 4 bean rolls. However, the efficiency is low during manual preparation of materials, the speed is slow, and the overall production capacity is still low. Summary of the Invention:

[0006] In view of the above problems, the present invention effectively increases the output of bean rolls by a large margin, greatly reduces the labor cost, and can further improve the stability and controllability of product quality, and provides a sandwich bean roll filling and rolling machine that can meet automatic filling and automatic rolling.

[0007] To achieve the above object, the present invention is realized through the following technical solutions: An automatic bean curd skin stuffing rolling machine, comprising: a stuffing machine, a moving slide located below the stuffing machine for supporting the stuffing machine, a rolling and forming mechanism located at the front end of the moving slide, an electrical control unit located on the right side of the moving slide, and an overall frame for supporting the stuffing machine, the moving slide, and the rolling and forming mechanism;

[0008] The stuffing machine includes a stuffing machine hopper, a stuffing machine motor located behind the stuffing machine hopper, a stuffing machine screw housing located in front of the stuffing machine hopper, stuffing machine fixing tie rods fixedly arranged on both sides of the stuffing machine screw housing, a stuffing machine pump head located in front of the stuffing machine screw housing, a stuffing machine discharge pipe communicating with the stuffing machine pump head, a stuffing machine pump head locking nut for locking the stuffing machine screw housing and the stuffing machine pump head, and a stuffing machine base plate located at the bottom of the stuffing machine hopper, the stuffing machine motor, and the stuffing machine screw housing;

[0009] The moving slide includes a fixing frame for the stuffing machine moving mechanism, two slide rails mounted on the fixing frame for the stuffing machine moving mechanism through guide rail seats, and a screw slide table fixedly connected to the stuffing machine base plate;

[0010] The rolling and forming mechanism includes a rolling and forming machine and a cloth pressing mechanism located above the rolling and forming machine. The rolling and forming machine includes two stuffing rolling push rod cylinders, a joint bearing connected to the two stuffing rolling push rod cylinders, a stuffing rolling push rod installed between the joint bearings, a cloth clamping rod fixed to the stuffing rolling push rod through a cloth clamping rod fixing nut located above the stuffing rolling push rod, and a stuffing rolling flexible mesh cloth wound around the stuffing rolling push rod. A stuffing rolling platform is installed directly below the stuffing rolling flexible mesh cloth. Stuffing rolling demolding grooves and stuffing receiving grooves are respectively formed at the front and rear ends of the stuffing rolling platform. Mesh cloth fixing seats cooperating with the mesh cloth fixing blocks are respectively arranged on the outer sides of the front and rear ends of the stuffing rolling platform. The front and rear ends of the stuffing rolling flexible mesh cloth are perforated and can be inserted into the mesh cloth fixing blocks. Any one end of the stuffing rolling flexible mesh cloth must pass through the stuffing rolling push rod and the cloth clamping rod;

[0011] The cloth pressing mechanism includes a cloth pressing rod vertical arm and a cloth pressing rod horizontal arm erected above the cloth pressing rod vertical arm. A downward cloth pressing cylinder located directly above the stuffing receiving groove is arranged in the middle of the cloth pressing rod horizontal arm. A cloth pressing rod is installed at the bottom of the downward cloth pressing cylinder. Left and right cloth pressing rod guide rods are installed on the upper surfaces of both ends of the cloth pressing rod. The left and right cloth pressing rod guide rods are respectively erected on a left guide rod linear bearing seat and a right guide rod linear bearing seat;

[0012] The electrical control unit includes a control box and a PLC located inside the control box. A display screen is arranged on the front surface of the control box, and a main power switch is arranged above the display screen.

[0013] The overall frame includes a stuffing rolling machine support frame, adjustable furniture feet installed at the bottom of the stuffing rolling machine support frame, two stuffing recovery barrels placed inside the support feet of the stuffing rolling machine, and a tofu skin placement table fixed to the left side of the stuffing rolling machine support frame.

[0014] Preferably, a support arm of a cloth pressing guide rod proximity switch is installed at the top of the downward cloth pressing air cylinder. A cloth pressing return proximity switch 17 is provided on the support arm of the cloth pressing guide rod proximity switch. The cloth pressing return proximity switch is located directly above the left cloth pressing rod guide rod and is on the same central axis as the left cloth pressing rod guide rod.

[0015] Preferably, four guide rail sliders are installed in parallel below the base plate of the stuffing machine. The four guide rail sliders are installed on two slideway guide rails. A lead screw slideway is installed in the middle between the two parallel slideway guide rails. The middle of the base plate of the stuffing machine is fixed to the slideway moving seat of the lead screw slideway. The lead screw slideway is connected to a slideway motor.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The stuffing machine moves back and forth on the slideway through the drive of the slideway moving seat to automatically and evenly stuff, and after rolling, it is full and symmetrical. After the stuffing is given, one roll is completed in one second, (diameter 20 - 25mm, length 520mm, cut into 8 equal parts). The production cycle is short, the hands do not directly touch the stuffing, the chance of the product being infected by bacteria is small, the taste is good, and the flavor is fresh. In comparison with the traditional manual cigarette rolling machine used to roll bean rolls, the cigarette rolling machine can roll 360 catties of bean rolls per shift, while the stuffing rolling machine invented by our company can produce 1500 catties per person per shift by one person, which is 4.2 times that of the manual cigarette rolling machine. When using the cigarette rolling machine to roll bean rolls, manual stuffing is required. Pouring the stuffing into the stuffing tray requires manual scraping to level it. Using a spatula to scrape the stuffing into the stuffing groove, then manually placing a whole piece of tofu skin, and manually using a piercing rod to pull and roll to drive the wrapping cloth to roll. The manual feeding efficiency is low, the speed is slow, the labor intensity is high, and the production capacity is low. While using the stuffing rolling machine invented by our company, the labor intensity is low, the employees work easily, and they can sit or stand and operate easily and switch the body state at will.

[0018] 2. When using the cigarette rolling machine to prepare the stuffing, a large amount of manual contact with the stuffing will cause bacterial contamination, while the stuffing rolling machine of the present invention does not require manual direct contact with the stuffing. The stuffing runs in a closed state inside the stuffing machine and will not be directly exposed to the air all the time, thus preventing the stuffing from being contaminated by miscellaneous bacteria.

[0019] 3. The movement of the stuffing machine is controlled by a servo motor. After receiving the PLC command instruction, the blades of the vane pump of the stuffing machine are evenly distributed, and the extruded stuffing is uniform. Compared with the bean rolls rolled by hand and the cigarette rolling machine, the size of the bean rolls is much more controllable. The weight of the stuffing is determined by the number of output pulse signal values, thereby controlling the weight of the bean rolls. The influence of human factors is reduced.

The middle of the stuffing machine base plate 33 is fixed to the slideway moving seat 56 of the lead screw slide table 26, and the lead screw slide table 26 is connected to a slideway motor 36.

[0040] Specifically, first start the control unit. After the stuffing machine receives the PLC instruction, the servo motor on the slideway mechanism controls the back-and-forth movement of the slideway moving seat. The slideway moving seat drives the stuffing machine base plate, thereby driving the stuffing machine main body on the stuffing machine base plate to move back and forth and start and stop.

[0041] The action process of the stuffing machine for giving stuffing back and forth: After the Plc instruction starts the start switch at the left end of the slideway moving seat, the metal induction proximity block at the rear runs to the start / stop switch 55 at the left end of the stuffing machine for giving stuffing and touches it, triggering the start of the stuffing machine motor. The motor causes the auger to drive the blades in the vane pump to rotate, thereby achieving stuffing the stuffing receiving groove. When the metal induction proximity block at the front continues to run to the start / stop switch at the right end of the stuffing machine for giving stuffing and touches it, the entire stuffing of the stuffing receiving groove is completed. Then it continues to run to the stop switch at the right end of the slideway moving seat and touches it, and the slideway moving seat immediately stops continuing to run.

[0042] After the Plc instruction starts the start switch 57 at the right end of the slideway moving seat, the metal induction proximity block 60 at the front runs to the start switch 59 at the right end of the stuffing machine for giving stuffing and touches it, triggering the start of the stuffing machine motor 28. The motor causes the auger to drive the blades in the vane pump to rotate, thereby achieving stuffing the stuffing receiving groove 45. When the metal induction proximity block 61 at the rear continues to run to the start / stop switch 55 at the left end of the stuffing machine for giving stuffing and touches it, the entire stuffing of the stuffing receiving groove 45 is completed. Then it continues to run to the stop switch 54 at the left end of the slideway moving seat and touches it, and the slideway moving seat 56 immediately stops continuing to run, completing all the actions of one round trip of stuffing.

[0043] Rolling action process: Turn on the main power switch 13 and the pneumatic switch, then start the automatic switch. The PLC instructs the cloth pressing cylinder 19 to start and drive the cloth pressing rod 20 to move downward to press the rolled stuffing flexible mesh cloth 46 into the stuffing receiving groove 45. When the cloth pressing rod 20 then returns to the origin and touches the cloth pressing return proximity switch 17, the start switch 53 at the left end of the sliding table moving seat is immediately activated. The metal induction proximity block 61 at the rear runs to the start / stop switch 55 at the left end of the stuffing feeder and touches it, triggering the start of the stuffing feeder motor 28. The motor drives the auger to drive the blades in the vane pump to rotate, thus achieving stuffing the stuffing receiving groove 45. When the metal induction proximity block 60 at the front continues to run to the start / stop switch 59 at the right end of the stuffing feeder and touches it, the entire stuffing of the stuffing receiving groove 45 is completed. It continues to run to the stop switch 58 at the right end of the sliding table moving seat and touches it, and the sliding table moving seat 56 immediately stops sliding. During the whole process, manual assistance is required to take a piece of bean skin from the bean skin placement table 4 and place it flat on the stuffing rolling platform 51. Then, after the sliding table moving seat 56 stops sliding, the push rod cylinder 9 starts and drives the stuffing rolling push rod 44 and the cloth clamping rod 43 installed on the air rod, as well as the stuffing rolling flexible mesh cloth 46 between the stuffing rolling push rod 44 and the cloth clamping rod 43, to roll forward on the stuffing rolling platform 51 to the stuffing demolding groove 47 for demolding. Then, the operator immediately takes away the rolled bean roll product. At the same time, the push rod cylinder 9 immediately retracts to the origin and touches the push rod return proximity switch 5. The PLC then instructs the cloth pressing cylinder 19 to start again and drive the cloth pressing rod 20 to move downward to press the rolled stuffing flexible mesh cloth 46 into the stuffing receiving groove 45. Immediately after the cloth pressing rod 20 returns to the origin and touches the cloth pressing return proximity switch 17, the start switch 57 at the left end of the sliding table moving seat is activated. The metal induction proximity block 60 at the front runs to the start / stop switch 59 at the right end of the stuffing feeder and touches it, triggering the start of the stuffing feeder motor 28. The motor drives the auger to drive the blades in the vane pump to rotate, thus achieving stuffing the stuffing receiving groove 45. When the metal induction proximity block 61 at the rear continues to run to the start / stop switch 55 at the left end of the stuffing feeder and touches it, the entire stuffing of the stuffing receiving groove 45 is completed. It continues to run to the stop switch 54 at the left end of the sliding table moving seat and touches it, and the sliding table moving seat 56 immediately stops sliding. During the whole process, manual assistance is required to take a piece of bean skin from the bean skin placement table 4 and place it on the stuffing rolling platform 51. When the sliding table moving seat 56 immediately stops sliding, the push rod cylinder 9 starts and drives the stuffing rolling push rod 44 and the cloth clamping rod 43 installed on the air rod, as well as the stuffing rolling flexible mesh cloth 46 between the stuffing rolling push rod 44 and the cloth clamping rod 43, to roll forward on the stuffing rolling platform 51 to the stuffing demolding groove 47 for demolding. Then, the operator immediately takes away the rolled bean product, completing all the actions of rolling the bean roll for one round trip. The push rod cylinder 9 immediately retracts to the origin and touches the push rod return proximity switch 5 to start the second round of rolling.
