Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to an automatic dough mixer. Background Art

[0002] Modern automatic dough mixers can control the ratio of water to flour, adjusting the dosage through electronic and electrical systems. This control method not only improves dough quality and ensures consistent mixing, but also reduces the need for manual operation and improves production efficiency. However, some challenges remain. For example, after the dough mixing process is completed, the dough needs to be removed from the dough hopper. Existing dough mixers cannot effectively control the degree of rotation of the dough hopper, and the operator may need to manually adjust the rotation, which not only increases the workload but also reduces overall production efficiency. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the existing technology and propose to design an automatic dough mixer that can accurately control the degree of flipping of the dough bucket, avoid manual adjustment again, and improve production efficiency.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] An automatic dough mixer, comprising a frame and:

[0006] The dough bucket has two ends that are rotatably connected to the two sides of the frame respectively. A stirring mechanism is arranged in the dough bucket. The stirring shaft of the stirring mechanism is connected to the output end of the reducer installed on the frame. The reducer drives the stirring mechanism to move, thereby achieving the purpose of automatic dough kneading; one end of the dough bucket is connected to a worm gear, which meshes with a horizontal worm located below it and arranged on the frame. One end of the worm gear is connected to a tipping bucket pulley, which is connected to a tipping bucket motor wheel through a transmission belt. The tipping bucket motor wheel is installed at the output end of the tipping bucket motor. When the tipping bucket motor is started, the tipping bucket pulley is driven to rotate through the transmission belt, which causes the worm gear to rotate, thereby driving the worm gear to rotate, and the worm gear drives the dough bucket to flip;

[0007] The switch baffle is fixedly installed on the upper end of the worm gear side;

[0008] There are two limit switches installed on the frame, namely limit switch a and limit switch b. Limit switch a and limit switch b are located on both sides of the switch block. When the switch block contacts limit switch a or limit switch b, the dough bucket stops flipping;

[0009] The proximity switch baffle is fixedly installed on the lower end of the worm gear side;

[0010] Two proximity switches are provided, namely proximity switch a and proximity switch b. Proximity switch a and proximity switch b are fixed on an arc-shaped mounting plate, and the arc-shaped mounting plate is mounted on the frame.

[0011] Furthermore, when the proximity switch a contacts the proximity switch baffle, the dough bucket stops flipping; and the stirring mechanism can only work when the proximity switch b contacts the proximity switch baffle.

[0012] Furthermore, a block mechanism is provided on the frame, comprising a fixed base, a block support, a block cylinder, and a block; the fixed base is mounted on the frame, the block support is mounted on the fixed base and can rotate relative to the fixed base, the block is mounted on the block support and can rotate with the block support to prevent the dough bucket from turning over; the block cylinder is mounted on the frame, the piston rod of the block cylinder is fixed to the block support, and is used to drive the block support to rotate. When the dough bucket is in a vertical position, the block just prevents the dough bucket from turning over. When the dough bucket needs to be turned over, the block cylinder needs to first drive the block support to rotate, thereby moving the block to one side of the dough bucket to prevent the dough bucket from turning over.

[0013] Furthermore, an upper cover is installed on the top of the dough hopper, and an opening cylinder is installed on both sides of the frame. The piston rod of the opening cylinder is connected to the end of the upper cover for opening and closing the upper cover.

[0014] Furthermore, a cover opening limit switch and a cover closing limit switch are respectively provided at both ends of the cover opening cylinder.

[0015] Furthermore, a noodle adding port and a water adding port are provided on the upper cover, which are used to add noodles and water into the noodle hopper respectively.

[0016] Furthermore, the frame includes a main frame and shields arranged on both sides of the main frame.

[0017] Furthermore, the input end of the speed reducer is connected to the output end of the main motor mounted on the frame via a sprocket or a belt, which has lower noise and better transmission efficiency.

[0018] The utility model is also equipped with an electrical system, which adopts PLC intelligent control and is connected to electrical components such as the tipping bucket motor, the block cylinder, and the main motor. It automatically controls the main tipping bucket motor, the block cylinder, and the main motor, and automatically completes a series of automated actions such as kneading dough, flipping and returning the dough bucket to the center, and automatically opening and closing the upper cover to achieve automatic dough kneading.

[0019] Technical effects of this utility model:

[0020] Compared to existing technologies, the automatic dough mixer of the present invention can precisely control the flipping and centering of the dough bucket. Specifically, when the dough bucket flips, the bucket stops flipping when the switch block contacts limit switch a or limit switch b. When the dough bucket returns to the center, the bucket stops flipping when the proximity switch block contacts proximity switch a. The mixing mechanism only operates when the proximity switch block contacts proximity switch b. This avoids the problem of manual readjustment due to the dough bucket not flipping properly, and also avoids the risk of starting the mixing operation when the dough bucket is not flipped properly, thus ensuring safety and reliability.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0029] Example 1:

[0030] like Figure 1-4As shown, the present embodiment involves an automatic dough mixer, including a frame 1, a dough bucket 2, a stirring mechanism, a block mechanism, a reducer 3, a worm gear 5, a worm 6, a tipping bucket motor 10, a switch baffle 11, a limit switch a1201, a limit switch b1202, a proximity switch baffle 13, a proximity switch a14, a proximity switch b15, and an upper cover 21.

[0031] The frame 1 includes a main frame 101 and shields 102 provided on both sides of the main frame 101 , and the shields 102 serve as a protective device.

[0032] An upper cover 21 is provided above the noodle hopper 2 , and a noodle adding port 25 and a water adding port 26 are provided on the upper cover 21 for adding noodles and water into the noodle hopper 2 respectively.

[0033] The two ends of the dough bucket 2 are respectively connected to the two sides of the frame 1 for rotation. A stirring mechanism is provided in the dough bucket 2. The stirring shaft of the stirring mechanism is connected to the output end of the reducer 3 installed on the frame 1 through a coupling 4. The input end of the reducer 3 is connected to the output end of the main motor 27 installed on the frame 1 through a sprocket or belt, so that the reducer 3 drives the stirring mechanism to operate and perform the dough kneading operation. The other end of the dough bucket 2 is connected to the worm gear 5, which is engaged with the horizontal worm 6 located below it and installed on the frame 1. One end of the worm gear 6 is connected to the bucket pulley 7, which is connected to the bucket motor wheel 9 through a transmission belt 8. The bucket motor wheel 9 is installed at the output end of the bucket motor 10. When the bucket motor 10 is started, the bucket pulley 7 is driven to rotate through the transmission belt 8, causing the worm 6 to rotate, thereby driving the worm gear 5 to rotate, and the worm gear 5 drives the dough bucket 2 to flip.

[0034] The switch block 11 is fixedly mounted on the upper side of the worm gear 5. Two limit switches are provided, both mounted on the frame 1, namely limit switch a1201 and limit switch b1202. Limit switches a1201 and b1202 are located on either side of the switch block 11. When the switch block 11 contacts limit switch a or limit switch b, the dough hopper 2 stops turning.

[0035] The proximity switch block 13 is fixedly mounted on the lower side of the worm gear 5. Two proximity switches are provided: proximity switch a14 and proximity switch b15. These switches are fixed to an arc-shaped mounting plate 16, which is mounted on the frame 1. When proximity switch a14 contacts proximity switch block 13, the dough hopper 2 stops turning; the stirring mechanism only operates when proximity switch b15 and proximity switch block 13 are in contact. The coordination between proximity switches a14 and b15, and the linkage between proximity switch b15 and the stirring mechanism, enables the stirring mechanism to continue stirring even when the dough hopper 2 is in its proper position, ensuring safe and effective operation.

[0036] The stopper mechanism is located on the side of the frame 1 near the reducer 3 and comprises a fixed base 17, a stopper support 18, a stopper cylinder 19, and a stopper 20. The fixed base 17 is mounted on the frame 1, the stopper support 18 is mounted on the fixed base 17 and can rotate relative to the fixed base 17, and the stopper 20 is mounted on the stopper support 18 and can rotate with the stopper support 18, thereby preventing the dough hopper 2 from turning over. The stopper cylinder 19 is mounted on the frame 1, and its piston rod is fixed to the stopper support 18, which is used to drive the stopper support 18 to rotate. When the dough hopper 2 is in a vertical position, the stopper 20 prevents the dough hopper 2 from turning over. To turn the dough hopper 2 over, the stopper cylinder 19 first drives the stopper support 18 to rotate, thereby moving the stopper 20 to the side of the dough hopper 2 to prevent it from turning over.

[0037] The upper cover 21 is equipped with an opening cylinder 22. Specifically, a set of opening cylinders 22 are installed on both sides of the frame 1. The piston rods of the opening cylinders 22 are connected to the ends of the upper cover 21 for opening and closing the upper cover 21. Preferably, two sets of opening cylinders 22 are installed on the same side of the opening cylinders 22, so that the upper cover 21 can be raised and lowered more smoothly. An opening limit switch 23 and a closing limit switch 24 are respectively provided at both ends of the opening cylinders 22. Specifically, as Figure 5 As shown, the lid opening limit switch 23 and lid closing limit switch 24 are located at the upper and lower limits of the lid opening cylinder 22, respectively. The piston inside the lid opening cylinder 22 is magnetic. When the upper cover 21 is closed and the piston of the lid opening cylinder 22 is at the lower limit, the magnetic force causes the lid closing limit switch 24 to close, providing the electrical system with a signal that the upper cover 21 is at the lower limit. Conversely, when the upper cover 21 is opened, the piston is at the upper limit, causing the lid opening limit switch 23 to close, providing the electrical system with a signal that the upper cover 21 is at the upper limit.

[0038] The present invention is also equipped with an electrical system, which adopts PLC intelligent control and is connected to electrical components such as the tipping bucket motor 10, the block cylinder 19, the cover opening cylinder 22, and the main motor 27. It automatically controls the main tipping bucket motor 10, the block cylinder 19, the cover opening cylinder 22, and the main motor 27, and automatically completes a series of automated actions such as kneading dough, turning over and returning the dough bucket 2, and automatically opening and closing the upper cover 21, thereby realizing automatic kneading dough.

[0039] Working principle: When the present invention is in use, flour is added to the dough bucket 2 through the flour adding port 25, and water is added to the dough bucket 2 through the water adding port 26. After the flour and water adding actions are completed, the dough mixer is started and begins to work automatically. During the working process, the electrical system automatically controls the main motor 27. After the dough is kneaded, the cover opening cylinder 22 and the block cylinder 19 work simultaneously. The cover opening cylinder 22 pushes up the upper cover 21 to complete the cover opening. The block cylinder 19 pushes the block support 18 to rotate around the fixed seat 17, so that the block support 18 is disengaged from the block 20. Then the bucket motor 10 drives the bucket pulley 7 to rotate through the transmission belt 8, and the bucket pulley 7 drives the worm 6 to rotate. The worm gear 5 drives the dough bucket 2 to flip to the left (such as Figure 1 and Figure 6 As shown, the switch block 11 contacts the limit switch a1201, stopping the dough hopper 2 from turning. The electrical system controls the main motor 27 to rotate in a regular, alternating forward and reverse direction, discharging the kneaded dough from the dough hopper 2. The dumping motor 10 then rotates in the reverse direction, and the proximity switch block 13, fixed to the worm gear 5, rotates with the dough hopper 2. The proximity switch block 13 first passes the proximity switch b15 and then continues to rotate. When the proximity switch block 13 contacts the proximity switch a14, the dough hopper 2 stops turning. The dough hopper 2 is in an upright position, and the proximity switch block 13 contacts both the proximity switches a14 and b15. At this point, the lid opening cylinder 22 and the stopper cylinder 19 operate simultaneously. The lid opening cylinder 22 drives the upper lid 21 downward, completing the lid closing process. The stopper cylinder 19 then drives the stopper support 18 back, which rotates around the fixed base 17 until it returns to its original position, returning to the initial state of adding water and dough, completing a cycle.

[0040] The proximity switch b15 has a lid-opening parking function. The stirring mechanism can only work continuously after the proximity switch b15 contacts the proximity switch block 13. The proximity switch a14 is a switch for detecting the upright state of the dough bucket 2. Only when the proximity switch block 13 contacts the proximity switch a14 can the upper cover 21 be opened and closed.

[0041] Figure 1 When the noodle bucket 2 needs to flip right (backward), the upper cover 21 is opened, the block support 18 is opened, the noodle bucket 2 flips backward, the switch block 11 contacts the limit switch b1202, and the flipping action is completed. The noodle bucket 2 can be cleaned as needed. After the cleaning work is completed, the noodle bucket 2 flips left and returns to normal. When the proximity switch block 13 contacts the proximity switch a13, the noodle bucket 2 stops rotating. At this time, the noodle bucket 2 is not in the upright position. If the left flip button is continued to be pressed, the proximity switch block 13 and the proximity switch b15 will completely disengage. Then, the right flip button is pressed. The proximity switch block 13 first contacts the proximity switch b15 and then continues to flip. When the proximity switch block 13 contacts the proximity switch a14, the noodle bucket 2 stops flipping and is in the middle upright position, rotating back to its original position.

The patent protection scope of the present utility model includes but is not limited to the above-mentioned specific implementation methods. Any appropriate changes or modifications made to them by ordinary technicians in the relevant technical field that comply with the claims of the present utility model shall fall within the patent protection scope of the present utility model.
