Description

Technical Field

[0001] This utility model relates to the field of biscuit production technology, and in particular to a dough mixing and stirring device for biscuit production. Background Technology

[0002] Biscuits are foods made primarily from cereal flour, with added sugar, oil, and other ingredients, through processes such as mixing the flour (or batter), shaping, and baking (or frying). They also include foods for which cream, egg whites, cocoa, chocolate, etc., are added before or after cooking (either on the surface or inside the product).

[0003] The production process can generally be divided into stages such as raw material preparation, mixing, shaping, baking, and packaging; mixing is the process of mixing and blending various raw materials. During mixing, ingredients such as flour, sugar, eggs, butter, and milk powder are put into a machine in proportion and mixed evenly with a mixer to form a uniform cookie dough.

[0004] A horizontal mixer is a type of dough mixing equipment, and it is a core piece of equipment in large baking factories, central kitchens, and industrial pasta production lines for processing large volumes of high-viscosity dough (such as bread dough, pizza dough, and some hard biscuit dough). Its key feature is that the mixing shaft is placed horizontally, and the mixing tank is U-shaped or rectangular.

[0005] When a horizontal mixer is working, gears, chains, or belts transmit power from the reducer to the mixing shaft, causing the hooks on the mixing shaft to mix the raw materials into dough. The mixing cylinder cannot move while mixing the dough, so relying solely on the hooks for mixing results in low efficiency in water incorporation into the raw materials before dough formation, affecting the speed of dough formation. Utility Model Content

[0006] The purpose of this invention is to provide a dough mixing device for biscuit production, which can shake the mixing tank during the mixing of raw materials, increase the contact area between water and raw materials in the mixing tank, promote the rapid integration of water and raw materials, and improve the dough forming speed.

[0007] To achieve the above objectives, a dough mixing device for biscuit production is provided, comprising a housing, a second electric push rod rotatably connected to the bottom of the housing, two support plates symmetrically fixed to the inner wall of the housing, each support plate having a groove on its surface, a tension shaft and a drive shaft inside the housing, the two ends of the drive shaft passing through the two support plates and rotatably connected to them, and the two ends of the tension shaft passing through the grooves on the two support plates and slidably connected to them, a drive mechanism mounted on opposite ends of the two support plates, the drive shaft and tension shaft passing through the drive mechanism and fixedly connected to it, and a... The device includes a drive motor, with its shaft connected to a transmission shaft via a coupling. A mixing cylinder is mounted at one end of the device housing, and the housing surface has a groove to accommodate the mixing cylinder. A mixing shaft is rotatably connected to this groove, passing through and rotatably connecting to the mixing cylinder. A stirring hook is located within the mixing cylinder, and the mixing shaft passes through and is fixedly connected to the hook. The housing surface has a first slot and a second slot. One end of the drive mechanism extends through the second slot to the outside of the housing, and one end of the mixing shaft is fixedly connected to the drive mechanism. The upper end of a second electric push rod passes through the first slot out of the housing, and is rotatably connected to the bottom of the mixing cylinder. This mechanism allows the mixing cylinder to vibrate during mixing, increasing the contact area between water and ingredients, promoting rapid mixing, and improving dough forming speed.

[0008] According to the aforementioned dough mixing and stirring device for biscuit production, an automatic tensioning mechanism is fixedly connected to the bottom of the device housing, and the automatic tensioning mechanism is located between two support plates. The tensioning shaft passes through the automatic tensioning mechanism and is rotatably connected to it. The automatic tensioning mechanism keeps the drive mechanism in a tensioned state, ensuring the transmission efficiency of the drive mechanism.

[0009] According to the aforementioned dough mixing device for biscuit production, the automatic tensioning mechanism comprises a connecting block, a pulley, a wire rope, a tension sensor, a motor, a reducer, and a winch. The tension sensor, motor, reducer, and winch are fixedly connected to the bottom of the equipment housing. The motor shaft is connected to the input shaft of the reducer via a coupling, and the reducer's output shaft is connected to the winch shaft via a coupling. The wire rope is wound by the winch. The connecting block is fixedly connected to the surface of the tensioning shaft. The pulley is welded to the lower end of the connecting block. One end of the wire rope passes through the pulley and extends to the upper end of the tension sensor, and the wire rope is fixedly connected to the tension sensor. The motor increases torque through the reducer, causing the winch to wind the wire rope. The wire rope pulls the connecting block downwards through the pulley, causing the tensioning shaft to drive the tensioning pulley to tension the drive mechanism. The tension sensor detects the tension applied by the wire rope to the pulley. Once the required tension is reached, the controller provides feedback to stop the motor.

[0010] According to the aforementioned dough mixing device for biscuit production, a first electric push rod is provided on both sides of the mixing cylinder, with the output end of the first electric push rod facing the mixing cylinder. The first electric push rod is fixedly connected to the surface of the equipment housing. Fixed sleeves for inserting the first electric push rods are fixedly connected to both ends of the mixing cylinder. The fixed sleeves are inserted when the opening of the mixing cylinder is vertically upward. When the opening of the mixing cylinder is vertically upward, the first electric push rod can be inserted into the fixed sleeve to stabilize the mixing cylinder, achieving the effect of keeping the mixing cylinder stationary while the stirring hook alone mixes the raw materials.

[0011] According to the dough mixing device for biscuit production, a support block is fixedly connected to the bottom of the groove of the device shell, and the upper end of the support block is slidably connected to the bottom of the mixing cylinder. The support block supports the mixing cylinder, reduces the load on the mixing shaft, and makes the shaking of the mixing cylinder more stable.

[0012] According to the aforementioned dough mixing and stirring device for biscuit production, a controller is fixedly connected to the side of the device housing. The controller controls the drive motor, the first electric push rod, and the second electric push rod. The controller receives detection signals from a tension sensor to automatically tension the transmission belt driven by the motor. The controller controls the operating status of the device and collects and processes sensor signals from the device before providing feedback.

[0013] According to the aforementioned dough mixing and stirring device for biscuit production, the controller surface is equipped with a main switch, an emergency stop button, a start button, a tilt mode button, and a gear adjustment knob. This allows operators to control and adjust the device's operating status and mode via the controller.

[0014] According to the aforementioned dough mixing device for biscuit production, the driving mechanism comprises a driven wheel, a tensioning wheel, a driving wheel, and a transmission belt. The mixing shaft passes through the middle of the driven wheel and is fixedly connected to it. The tensioning shaft passes through the middle of the tensioning wheel and is fixedly connected to it. The transmission shaft passes through the middle of the driving wheel and is fixedly connected to it. The transmission belt passes sequentially over the surfaces of the driven wheel, tensioning wheel, and driving wheel and is connected end-to-end. The transmission belt extends to the outside of the equipment housing through a first slot. The cooperation of the driven wheel, tensioning wheel, driving wheel, and transmission belt causes the drive motor to drive the mixing shaft to rotate, thus mixing the raw materials in the mixing tank.

[0015] The above solution has the following beneficial effects: when the second electric push rod drives the drive motor and drive mechanism to drive the stirring hook to stir the raw materials, the stirring cylinder shakes, increasing the contact area between water and raw materials in the stirring cylinder, promoting the rapid integration of water and raw materials, and improving the dough forming speed.

[0020] Reference Figure 1-6 This utility model discloses a dough mixing device for biscuit production, comprising a housing 1, a second electric push rod 6 rotatably connected to the bottom of the housing 1, two support plates 14 symmetrically fixed to the inner wall of the housing 1, each support plate 14 having a groove 15 on its surface, a tensioning shaft 16 and a drive shaft 17 inside the housing 1, with both ends of the drive shaft 17 passing through the two support plates 14 and rotatably connected to them, and both ends of the tensioning shaft 16 passing through the grooves 15 on the two support plates 14 and slidably connected to them, and a drive mechanism 8 installed at the opposite ends of the two support plates 14, with both the drive shaft 17 and the tensioning shaft 16 passing through the drive mechanism 8 and fixedly connected to it, and one end of each support plate 14 fixedly connected to... A drive motor 13 is connected, and the rotating shaft of the drive motor 13 is connected to the transmission shaft 17 via a coupling. A stirring cylinder 2 is installed at one end of the equipment housing 1, and a groove is provided on the surface of the equipment housing 1 to accommodate the stirring cylinder 2. A stirring shaft 9 is rotatably connected in the groove on the surface of the equipment housing 1, and the stirring shaft 9 passes through the stirring cylinder 2 and is rotatably connected to the stirring cylinder 2. A stirring hook 3 is provided in the stirring cylinder 2, and the stirring shaft 9 passes through the stirring hook 3 and is fixedly connected to the stirring hook 3. A first slot 11 and a second slot 12 are provided on the surface of the equipment housing 1. One end of the drive mechanism 8 extends through the second slot 12 to the outside of the equipment housing 1, and one end of the stirring shaft 9 is fixedly connected to the drive mechanism 8.

The wire rope 24 is wound up by the winch 28. The connecting block 22 is fixedly connected to the surface of the tensioning shaft 16. The pulley 23 is welded to the lower end of the connecting block 22. One end of the wire rope 24 passes through the pulley 23 and extends to the upper end of the tension sensor 25. The wire rope 24 is fixedly connected to the tension sensor 25. After the motor 26 increases the torque through the reducer 27, the winch 28 winds up the wire rope 24. The wire rope 24 pulls down the connecting block 22 through the pulley 23, which causes the tensioning shaft 16 to drive the tensioning wheel 19 to tension the drive mechanism 8. The tension sensor detects the tension applied by the wire rope 24 to the pulley 23. After the tension reaches the required level, the controller 4 feeds back to stop the motor 26 from working.

[0023] Both sides of the mixing cylinder 2 are equipped with first electric push rods 5, with the output end of the first electric push rod 5 facing the mixing cylinder 2.

When the opening of the mixing cylinder 2 is vertically upward, the first electric push rod 5 can be inserted into the fixed sleeve to stabilize the mixing cylinder 2, so that the mixing cylinder 2 remains stationary while the stirring hook 3 stirs the raw materials independently.

[0024] A support block 10 is fixedly connected to the bottom of the groove of the equipment shell 1, and the upper end of the support block 10 is slidably connected to the bottom of the mixing cylinder 2. The support block 10 supports the mixing cylinder 2, reduces the load on the mixing shaft 9, and makes the shaking of the mixing cylinder 2 more stable.

[0025] A controller 4 is fixedly connected to the side of the equipment housing 1. The controller 4 controls the drive motor 13, the first electric push rod 5, and the second electric push rod 6. The controller 4 receives the detection signal from the tension sensor to realize the automatic tensioning of the transmission belt 21 by the motor 26.

The transmission belt 21 extends to the outside of the equipment housing 1 through the first slot 11. The cooperation of the driven wheel 18, the tensioning wheel 19, the drive wheel 20, and the transmission belt 21 causes the drive motor 13 to drive the stirring shaft 9 to rotate, thus stirring the raw materials in the stirring tank 2.

[0028] Working principle: During use, the controller 4 controls the second electric push rod 6 to extend fully, the mixing cylinder 2 tilts, and the operator adds raw materials and water to the mixing cylinder 2. After completion, the second electric push rod 6 returns to its original position, and the mixing cylinder 2 becomes vertical. During mixing, the drive motor 13 works, and through the transmission of the drive mechanism 8, the drive shaft drives the mixing shaft 9 to rotate, causing the stirring hook 3 to stir the water and raw materials. At the same time, the second electric push rod 6 reciprocates, causing the mixing cylinder 2 to shake, promoting the rapid mixing of water and raw materials. The motor 26 increases the torque through the reducer 27, causing the winch 28 to wind up the wire rope 24. The wire rope 24 pulls down the connecting block 22 through the pulley 23, causing the tensioning shaft 16 to drive the tensioning wheel 19 to tension the transmission belt 21. The tension sensor detects the tension applied by the wire rope 24 to the pulley 23. After the tension reaches the required level, the controller 4 provides feedback to stop the motor 26.
