Description

Technical Field

[0001] The utility model relates to the technical field of dough mixers, and particularly relates to a transmission mechanism of a double-action and double-speed dough mixer. Background Art

[0002] Dough mixers are widely used in the food processing industry. For a good dough mixer, it is generally required to be double-action and double-speed, that is, the dough hook and the dough bucket can rotate at two different speeds simultaneously. The dough mixing effect directly affects the quality of the dough, the taste and appearance of the food.

[0003] However, when the existing dough mixer is in use, if the rotation speed of the dough hook is too slow, the dough will heat up, resulting in the dough not developing gluten, which seriously affects the quality of the dough. If the rotation speed of the dough hook is too fast, the transmission load will increase severely, seriously affecting the service life of the transmission device and generating excessive noise. Therefore, a transmission mechanism of a double-action and double-speed dough mixer is provided. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a transmission mechanism of a double-action and double-speed dough mixer. By setting a motor, a motor multi-wedge pulley, a stirring shaft multi-wedge pulley, a stirring shaft, a synchronous pulley on the main shaft, a main shaft, a synchronous pulley under the main shaft, a dough bucket turntable and a dough hook, the utility model solves the problems that when the existing dough mixer is in use, the dough mixing effect and the quality of the dough are poor, and at the same time, the service life of the dough mixing transmission mechanism is poor.

[0005] The technical solution adopted by the present utility model to solve its technical problems is a transmission mechanism of a double-acting and double-speed dough mixer, including a dough mixing bucket and a motor. A motor multi-wedge pulley is key-connected to the power output end of the motor. A multi-wedge belt is sleeved outside the motor multi-wedge pulley, and a stirring shaft multi-wedge pulley is arranged inside the multi-wedge belt. A stirring block is clamped inside the stirring shaft multi-wedge pulley, and a driving stirring shaft is clamped inside the stirring block. Stirring shaft bearing A and stirring shaft bearing B are arranged outside the stirring shaft, and stirring shaft bearing seats are connected to the outside of stirring shaft bearing A and stirring shaft bearing B by interference fit. A stirring shaft flange is welded to one end of the stirring shaft, and a dough hook for kneading dough is bolted to one side of the stirring shaft flange. A stirring shaft synchronous pulley is sleeved outside the stirring shaft, and an upper synchronous belt is sleeved outside the stirring shaft synchronous pulley. A driving main shaft upper synchronous pulley is arranged inside the upper synchronous belt, and a synchronous block is clamped inside the main shaft upper synchronous pulley. The main shaft is clamped inside the synchronous block. A universal bearing A is key-connected to the outside of the main shaft, and a main shaft upper bearing seat is connected to the outside of the universal bearing A by interference fit. A universal bearing B is sleeved on one side of the main shaft, and a main shaft lower bearing seat is connected to the outside of the universal bearing B by interference fit. A shaft sleeve is arranged on one side of the main shaft lower bearing seat, and a driving main shaft lower synchronous pulley is arranged on one side of the shaft sleeve. A lower synchronous belt is sleeved outside the main shaft lower synchronous pulley. A bucket shaft synchronous pulley is arranged inside the lower synchronous belt, and a belt tensioner is arranged inside the lower synchronous belt. A driving block is clamped inside the bucket shaft synchronous pulley, and a bucket shaft is clamped inside the driving block. Bucket shaft bearing A and bucket shaft bearing B are sleeved outside the bucket shaft, and bucket seat bearing seats are connected to the outside of bucket shaft bearing A and bucket shaft bearing B by interference fit. A bucket turntable for rotating the dough mixing bucket is fixed by screws at the end of the bucket shaft.

[0006] By adopting the above technical solution, when kneading the flour in the dough mixing bucket, the motor outside the dough mixing bucket converts the received electrical energy into mechanical energy. The motor drives the multi-wedge belt outside the motor multi-wedge pulley to rotate. Subsequently, the multi-wedge belt drives the stirring shaft multi-wedge pulley to rotate. Then, the stirring block inside the stirring shaft multi-wedge pulley drives the stirring shaft to rotate. Then, the stirring shaft flange outside the stirring shaft drives the dough hook to knead the flour in the dough mixing bucket. At the same time, the stirring shaft synchronous pulley outside the stirring shaft drives the upper synchronous belt to rotate. Subsequently, the upper synchronous belt drives the synchronous block inside the main shaft upper synchronous pulley to rotate. Then, the synchronous block drives the lower synchronous belt outside the main shaft lower synchronous pulley to rotate. At the same time, the belt tensioner inside the lower synchronous belt adjusts the tension of the lower synchronous belt. Then, the bucket shaft synchronous pulley inside the lower synchronous belt drives the bucket shaft inside the driving block to rotate. Subsequently, the bucket shaft drives the bucket turntable to rotate, so that the bucket turntable drives the dough mixing bucket to rotate, thereby improving the kneading efficiency and quality of the flour in the dough mixing bucket and simultaneously prolonging the service life of the kneading transmission mechanism.

[0007] Specifically, a tension pulley bearing is clamped inside the belt tension pulley. The tension pulley bearing is connected to the inside of the tension pulley bearing seat with an interference fit, and a tension pulley shaft is rotatably connected inside the tension pulley bearing.

[0008] By adopting the above technical solution, when adjusting the tension of the lower synchronous belt, the position of the tension pulley shaft changes inside the lower synchronous belt, causing the belt tension pulley outside the tension pulley shaft to contact the lower synchronous belt. When the lower synchronous belt rotates, the belt tension pulley rotates through the tension pulley bearing seat and the tension pulley bearing, thus facilitating the adjustment of the tension of the lower synchronous belt.

[0009] Specifically, wear-resistant layers are provided on the inner sides of the upper synchronous belt, the multi-wedge belt, and the lower synchronous belt.

[0010] By adopting the above technical solution, by providing wear-resistant layers on the inner sides of the upper synchronous belt, the multi-wedge belt, and the lower synchronous belt, the wear resistance of the upper synchronous belt, the multi-wedge belt, and the lower synchronous belt is improved, and the service life of the upper synchronous belt, the multi-wedge belt, and the lower synchronous belt is increased.

[0011] Specifically, lubricating grease is applied to the inner sides of the tension pulley bearing, the upper main shaft bearing seat, the mixing shaft bearing seat, the lower main shaft bearing seat, and the barrel seat bearing seat.

[0012] By adopting the above technical solution, by applying lubricating oil to the tension pulley bearing, the upper main shaft bearing seat, the mixing shaft bearing seat, the lower main shaft bearing seat, and the barrel seat bearing seat, the friction inside them is reduced, and the service life of the tension pulley bearing, the upper main shaft bearing seat, the mixing shaft bearing seat, the lower main shaft bearing seat, and the barrel seat bearing seat is increased.

[0013] Specifically, the input end of the motor is electrically connected to the power supply end of an external power source.

[0014] By adopting the above technical solution, by connecting to an external power source, the electrical equipment operates normally.

Then, the stirring shaft flange outside the stirring shaft drives the dough hook to knead the flour in the dough bucket. At the same time, the stirring shaft synchronous pulley outside the stirring shaft drives the upper synchronous belt to rotate. Subsequently, the upper synchronous belt drives the synchronous block inside the main shaft upper synchronous belt pulley to rotate. Then, the synchronous block drives the lower synchronous belt outside the main shaft lower synchronous belt pulley to rotate.

[0029] During use, when the tension of the lower synchronous belt 11 needs to be adjusted, the position of the tensioning wheel shaft 33 changes inside the lower synchronous belt 11, so that the belt tensioning wheel 10 outside the tensioning wheel shaft 33 contacts the lower synchronous belt 11, and when the lower synchronous belt 11 rotates, the belt tensioning wheel 10 rotates through the tensioning wheel bearing seat 34 and the tensioning wheel bearing 35, thereby facilitating the adjustment of the tension of the lower synchronous belt 11.

When the lower synchronous belt 11 rotates, the belt tension pulley 10 rotates through the tension pulley bearing seat 34 and the tension pulley bearing 35, thus facilitating the adjustment of the tension of the lower synchronous belt 11.
