Description

Technical Field

[0001] This utility model relates to the field of noodle presses, and more particularly to a noodle press with a movable auxiliary noodle press roller. Background Technology

[0002] Chinese Patent No. CN220000584U discloses an adjustable speed dough press machine, including a frame, a dough pressing mechanism, a dough cutting mechanism, and a speed adjustment knob. A motor is mounted on the frame, and the dough pressing mechanism is mounted on the frame and driven by the motor. The dough pressing mechanism includes a first dough pressing roller, a second dough pressing roller, and a roller adjustment knob. First mounting blocks are respectively provided at both ends of the first dough pressing roller. First mounting grooves for the first mounting blocks to slide in are provided at both ends of the frame. The roller adjustment knob drives the first mounting blocks to slide in the first sliding grooves through a first driving component. The first driving component is a connecting rod connected to the roller adjustment knob and the first mounting blocks at both ends.

[0003] When the roller adjustment knob in the above structure is rotated, it can move the first pressing roller closer to or away from the second pressing roller. However, when the first pressing roller and the second pressing roller are pressing the dough, since the second pressing roller cannot move, the dough will exert a reaction force on the first pressing roller due to the pressure of the two pressing rollers, thereby dragging the first pressing roller to move away from the second pressing roller. At this time, the first pressing roller will press the connecting rod between the roller adjustment knob and the first mounting block, which will cause the connecting rod to be easily damaged by the axial load generated when the first pressing roller is pressing. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies where the connecting rod is easily damaged by the axial load generated during the pressing operation of the first pressing roller. It provides a dough press machine with a movable secondary pressing roller that can reduce the axial load during the pressing operation of the secondary pressing roller.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0006] A noodle press with a movable secondary pressing roller includes a frame, a main pressing roller and a secondary pressing roller disposed within the frame, a guide groove at each end of the frame, and guide blocks at each end of the secondary pressing roller that guide the movement within the guide grooves when the secondary pressing roller moves. A driving component for pushing the guide blocks to move within the guide grooves is disposed within the frame. The driving component includes a motor disposed within the frame and a push rod that pushes the guide blocks to move within the guide grooves under the drive of the motor. A bearing component capable of withstanding the axial load brought by the push rod is disposed between the output shaft of the motor and the push rod.

[0007] Using the above scheme, when the main pressing roller and the auxiliary pressing roller are pressing dough, the dough will exert a reaction force on the auxiliary pressing roller due to the squeezing of the two pressing rollers. At this time, the push rod will apply an axial load to the output shaft of the motor, and the bearing component set between the output shaft of the motor and the push rod will bear the axial load transmitted by the push rod, thereby reducing the axial load on the output shaft of the motor and improving the service life of the motor.

[0008] Preferably, the load-bearing component is a thrust ball bearing.

[0009] Preferably, the thrust ball bearing is a double-direction thrust ball bearing.

[0010] Using the above scheme, the double-direction thrust ball bearing can withstand the axial load transmitted by the push rod. At the same time, the double-direction thrust ball bearing, through the design of two sets of symmetrical raceways and steel balls, can withstand axial forces in both clockwise and counterclockwise directions simultaneously, without the need to install an additional reverse bearing.

[0011] Preferably, the output shaft of the motor is provided with a lead screw that rotates together with the output shaft, the push rod is provided on the lead screw, a limiting hoop is provided in the frame to limit the push rod to rotate with the lead screw, a bearing seat is provided in the frame, and the bidirectional thrust ball bearing includes a shaft ring fixed to the lead screw, a seat ring fixed to the bearing seat, and rolling elements.

[0012] By adopting the above solution, the bearing race located in the bearing housing can bear the axial load when the ball applies an axial load to the lead screw. The axial load transmitted to the bearing race will be distributed to various parts of the bearing race by the rolling elements inside the double-acting thrust bearing, thereby reducing the axial load on the lead screw. Because the axial load on the lead screw is reduced, the axial load on the motor output shaft will also be reduced, thereby improving the service life of the motor.

[0013] This utility model has significant technical effects due to the adoption of the above technical solutions: when the main pressing roller and the auxiliary pressing roller are pressing dough, the dough will exert a reaction force on the auxiliary pressing roller due to the squeezing of the two pressing rollers. At this time, the push rod will apply an axial load to the output shaft of the motor, and the bearing component set between the output shaft of the motor and the push rod will bear the axial load transmitted by the push rod, thereby reducing the axial load on the output shaft of the motor and improving the service life of the motor.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0022] Example

[0023] A dough press with a movable auxiliary pressing roller, reference Figures 1-5 The machine includes a frame 1, a main pressing roller 2 and a secondary pressing roller 3 disposed within the frame 1. Each end of the frame 1 has a guide groove 4. Each end of the secondary pressing roller 3 has a guide block 5 disposed within the guide groove 4 to guide the movement of the secondary pressing roller 3. A drive component for pushing the guide block 5 to move within the guide groove 4 is disposed within the frame 1. The drive component includes a motor 6 disposed within the frame 1 and a push rod 10 that pushes the guide block 5 to move within the guide groove 4 under the drive of the motor 6. A bearing component capable of withstanding the axial load brought by the push rod 10 is disposed between the output shaft of the motor 6 and the push rod 10.

[0024] refer to Figures 4-6 The load-bearing component is a thrust ball bearing. In this embodiment, the thrust ball bearing is a double-direction thrust ball bearing 7. A lead screw 9 is provided on the output shaft of the motor 6 and rotates together with the output shaft. A push rod 10 is provided on the lead screw 9. A limiting hoop 8 is provided in the frame 1 to limit the rotation of the push rod 10 with the lead screw 9. A bearing seat 11 is provided in the frame 1. The double-direction thrust ball bearing 7 includes a shaft ring 701 fixed to the lead screw 9, a seat ring 702 fixed to the bearing seat 11, and rolling elements 703.

[0025] The specific load-bearing process is as follows: When the main pressing roller 2 and the auxiliary pressing roller 3 press the dough, the dough will exert a reaction force on the auxiliary pressing roller 3. The reaction force of the auxiliary pressing roller 3 will be transmitted to the push rod 10, that is, an axial load will be applied to the push rod 10. When the push rod 10 is subjected to an axial load, it will be transmitted to the bearing ring 702 set in the bearing housing 11. When the bearing ring 702 is subjected to an axial load, the rolling element 703 will distribute the axial load on the bearing ring 702 to various parts of the bearing ring 701, thereby reducing the axial load on the lead screw 9. Because the axial load on the lead screw 9 is reduced, the axial load on the output shaft of the motor 6 will also be reduced, thereby improving the service life of the motor 6.

All technical solutions falling within the scope of this utility model's concept are protected.
