Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1:

[0032] Please refer to in conjunction with Figures 1-7, the present invention provides a technical solution: a mechanical bearing for food machinery equipment, including a bearing outer ring 1 and a bearing inner ring 2. A connecting seat 3 is fixedly connected to the outer surface of the rear side of the bearing outer ring 1. A rotating shaft 4 rotatably penetrates through the outer surface of the connecting seat 3. An isolation column 5 is fixedly sleeved on the outer surface of the rotating shaft 4. A conical outer sleeve 6 is fixedly connected to the outer surface of the front side of the connecting seat 3. A conical inner sleeve 7 is arranged inside the conical outer sleeve 6. A fixing needle 8 movably penetrates through the outer surface of the conical outer sleeve 6. Three receiving grooves are circumferentially arranged on the outer surface of the conical inner sleeve 7. Steel balls 11 are arranged inside all three receiving grooves. The fixing needle 8 is fixedly connected to a connecting rod at one end close to the rotating shaft 4 of the conical outer sleeve 6. The other end of the connecting rod is fixedly connected to a limiting block 10. A limiting groove 9 is opened on the outer surface of the rotating shaft 4. A spring is fixedly connected inside the limiting groove 9. Specifically, the isolation column 5 is used to block between the bearing and the food machinery, preventing the bearing from directly contacting the surface of the food machinery, causing the conical inner sleeve 7 to move, driving the steel balls 11 to move. After the steel balls 11 move, the gaps between the multiple steel balls 11 become larger, enabling the fixing needle 8 to be pulled. At this time, pulling the fixing needle 8 causes the fixing needle 8 to drive the limiting block 10 to move, causing the limiting block 10 to disengage from the inside of the limiting groove 9, thereby applying force to the isolation column 5, causing the isolation column 5 to rotate, driving the rotating shaft 4 to rotate by ninety degrees, thereby cleaning the contact end face between the food machinery and the bearing, reducing the growth of bacteria, increasing the cleanliness of the food machinery during use. After the cleaning is completed, rotate the isolation column 5 so that the roller 29 at the other end of the isolation column 5 abuts against the surface of the food machinery, and then push the fixing needle 8. The fixing needle 8 presses the steel balls 11, causing the steel balls 11 to move inside the receiving grooves. When the needle rod of the fixing needle 8 contacts the steel balls 11, the steel balls 11 expand outward. When it is necessary to pull the fixing needle 8 outward, the steel balls 11 need to move to the right side of the conical outer sleeve 6 and expand outward, but due to the blocking force of the conical inner wall of the conical outer sleeve 6, the steel balls 11 cannot expand outward, so that the fixing needle 8 drives the limiting block 10 to insert into the limiting groove 9 to limit the rotating shaft 4 and prevent the rotating shaft 4 from rotating, thereby being able to avoid direct contact between the bearing and the food machinery and reducing the cleaning difficulty between the bearing and the end face of the food machinery.

[0033] In this embodiment, a first spring 12 is fixedly connected to the inner wall of the conical outer sleeve 6. The other end of the first spring 12 is fixedly connected to the outer surface of the conical inner sleeve 7. A lever 13 is fixedly connected to the outer surface of the top of the conical inner sleeve 7. A sliding groove is opened on the outer surface of the conical outer sleeve 6. The lever 13 is movably connected to the inside of the sliding groove. Specifically, when it is necessary to clean the end face between the bearing and the food machinery, pull the lever 13, causing the lever 13 to move inside the sliding groove, thereby causing the conical inner sleeve 7 to move and deforming the first spring 12.

[0034] In this embodiment, a movable post 27 is movably inserted inside the isolation post 5. A third spring 28 is fixedly connected inside the isolation post 5. The other end of the third spring 28 is fixedly connected to the movable post 27. A roller 29 is installed at the other end of the movable post 27. Specifically, when the isolation post 5 is rotated, when the roller 29 contacts the surface of the food machinery, the third spring 28 is compressed, and under the elastic force of the third spring 28, the vibration force generated by the food machinery is buffered to avoid affecting the service life of the isolation post 5.

[0035] In this embodiment, a connection disk is fixedly connected to the outer surface of the fixed needle 8. A fourth spring is fixedly connected between the connection disk and the tapered outer sleeve 6. The fourth spring is sleeved on the outer surface of the fixed needle 8. Specifically, when the steel ball 11 moves to provide a moving channel for the fixed needle 8, the fourth spring is reset, and the fourth spring drives the fixed needle 8 to reset.

[0036] In the specific implementation process, this bearing is installed on the food machinery. The isolation post 5 is used to block between the bearing and the food machinery to prevent the bearing from directly contacting the surface of the food machinery. When it is necessary to clean the end faces of the bearing and the food machinery, pull the lever 13, so that the tapered inner sleeve 7 moves, driving the steel ball 11 to move. After the steel ball 11 moves, the gap between the multiple steel balls 11 becomes larger, enabling the fixed needle 8 to be pulled. At this time, pull the fixed needle 8, so that the fixed needle 8 drives the limit block 10 to move, causing the limit block 10 to disengage from the inside of the limit groove 9, thereby applying force to the isolation post 5, causing the isolation post 5 to rotate, driving the rotating shaft 4 to rotate by ninety degrees, so as to clean the contact end faces between the food machinery and the bearing, reduce the growth of bacteria, and increase the cleanliness of the food machinery during use. After the cleaning is completed, rotate the isolation post 5 so that the roller 29 at the other end of the isolation post 5 abuts against the surface of the food machinery, and then push the fixed needle 8. The fixed needle 8 presses the steel ball 11, causing the steel ball 11 to move inside the receiving groove. When the needle rod of the fixed needle 8 contacts the steel ball 11, the steel ball 11 expands outward. When it is necessary to pull the fixed needle 8 outward, the steel ball 11 needs to move to the right side of the tapered outer sleeve 6 and expand outward, but due to the blocking force of the tapered inner wall of the tapered outer sleeve 6, the steel ball 11 cannot expand outward, so that the fixed needle 8 drives the limit block 10 to insert into the limit groove 9 to limit the rotating shaft 4 and prevent the rotating shaft 4 from rotating, thereby avoiding direct contact between the bearing and the food machinery and reducing the cleaning difficulty between the end faces of the bearing and the food machinery.

[0037] Embodiment 2:

[0038] Please refer to Figures 1-2 、 Figure 4 and Figure 8, the present invention provides a technical solution: Rotating seats 14 are fixedly connected to the outer surfaces on the left and right sides of the outer ring 1 of the bearing. A support shaft rotatably penetrates through the outer surface of the rotating seat 14. A telescopic column 15 is fixedly sleeved on the outer surface of the support shaft. The other end of the telescopic column 15 is fixedly connected to a mounting plate 16. Mounting holes 19 are formed on the outer surface of the mounting plate 16. Specifically, when installing this bearing, align the mounting holes 19 with the reserved holes on the mechanical equipment, and screw the mounting bolts into the corresponding positions of the mounting holes 19 and the reserved holes to install this bearing. When it is necessary to change the installation position, apply force to the telescopic column 15 so that the telescopic column 15 drives the support shaft to rotate and rotate the mounting plate 16 to a position parallel to the horizontal plane.

[0039] In this embodiment, a first gear 17 is fixedly sleeved on the outer surface of the support shaft. A connecting shaft is rotatably connected to the outer surface of the rotating seat 14. A second gear 18 is fixedly sleeved on the outer surface of the connecting shaft. The outer surfaces of the first gear 17 and the second gear 18 are movably engaged. Specifically, when the telescopic column 15 drives the support shaft to rotate, it drives the first gear 17 to rotate. The first gear 17 and the second gear 18 are engaged, so that a certain amount of force needs to be applied to the telescopic column 15 to rotate.

[0040] In this embodiment, the telescopic column 15 includes a fixed column and an adjustment column. Screw holes are formed on the outer surfaces of the fixed column and the adjustment column. The number of screw holes on the surface of the adjustment column is several and is arranged in a linear array. Adjusting handwheels are threadedly connected to the corresponding screw holes of the fixed column and the adjustment column. Specifically, by adjusting the position of the adjustment column in the fixed column and making the corresponding screw holes correspond to each other, screw the adjusting handwheels into the corresponding screw holes to limit the fixed column and the adjustment column, thereby adjusting the overall length of the telescopic column 15.

[0041] In the specific implementation process, when installing this bearing, align the mounting holes 19 with the reserved holes on the mechanical equipment, and screw the mounting bolts into the corresponding positions of the mounting holes 19 and the reserved holes to install this bearing. When it is necessary to change the installation position, apply force to the telescopic column 15 so that the telescopic column 15 drives the support shaft to rotate and drives the first gear 17 to rotate. The first gear 17 and the second gear 18 are engaged, so that a certain amount of force needs to be applied to the telescopic column 15 to rotate. Rotate the mounting plate 16 to a position parallel to the horizontal plane, and by adjusting the length of the telescopic column 15, make the bearing located at a precise position, and then install this bearing, so that different installation directions can be selected according to the actual installation requirements of the food machinery.

[0042] Embodiment 3:

[0043] Please refer to Figures 9-10, the present invention provides a technical solution: several balls 20 are arranged between the bearing outer ring 1 and the bearing inner ring 2. A heat dissipation cavity is formed inside the bearing outer ring 1. A plurality of ventilation holes 26 are arranged on the outer surface of the bearing outer ring 1 in a circumferential array, and the ventilation holes 26 extend to the inside of the heat dissipation cavity. The inner surface of the bearing outer ring 1 is fixedly communicated with a piston cylinder 21. A piston disc 22 is movably connected inside the piston cylinder 21. A piston rod 23 is fixedly connected to the bottom outer surface of the piston disc 22. An arc-shaped plate 24 is fixedly connected to the bottom outer surface of the piston rod 23. Specifically, when the bearing inner ring 2 makes the balls 20 rotate, the balls 20 contact the arc-shaped plate 24. As the balls 20 contact the arc-shaped plate 24, the arc-shaped plate 24 is squeezed, causing the piston rod 23 to move upward. The piston disc 22 drives the piston rod 23 to move upward, causing the piston disc 22 to move upward, and applying wind force to the heat dissipation cavity.

[0044] In this embodiment, a balance pipe is fixedly communicated with the outer surface of the piston cylinder 21. A one-way valve is installed inside the balance pipe, and the flow direction of the one-way valve is from the inside of the piston cylinder 21 towards the outside of the piston cylinder 21. Specifically, when the balls 20 separate from the surface of the arc-shaped plate 24, the pressure below the piston disc 22 reaches balance through the balance pipe.

[0045] In this embodiment, a connecting disc is fixedly connected inside the piston cylinder 21. The piston rod 23 movably penetrates through the outer surface of the connecting disc. A second spring 25 is fixedly connected between the connecting disc and the piston disc 22. Specifically, when the piston disc 22 moves upward, the second spring 25 deforms. When the balls 20 separate from the surface of the arc-shaped plate 24, the second spring 25 drives the arc-shaped plate 24 to reset.

[0046] In the specific implementation process, when the bearing inner ring 2 makes the balls 20 rotate, the balls 20 contact the arc-shaped plate 24. As the balls 20 contact the arc-shaped plate 24, the arc-shaped plate 24 is squeezed, causing the piston rod 23 to move upward. The piston disc 22 drives the piston rod 23 to move upward, causing the piston disc 22 to move upward, and applying wind force to the heat dissipation cavity. When the balls 20 separate from the surface of the arc-shaped plate 24, the second spring 25 drives the arc-shaped plate 24 to reset. The pressure below the piston disc 22 reaches balance through the balance pipe. The heat generated when the bearing is in use is discharged from the heat dissipation cavity, and the air flow rate is increased by applying pressure, thereby enhancing the heat dissipation effect and improving the service life of the bearing.

[0047] Working principle: When the present invention is in use, the bearing is installed on the food machinery. The isolation column 5 is used to block between the bearing and the food machinery, preventing the bearing from directly contacting the surface of the food machinery. When it is necessary to clean the end faces of the bearing and the food machinery, the lever 13 is pulled, causing the tapered inner sleeve 7 to move, driving the steel balls 11 to move. After the steel balls 11 move, the gaps between the multiple steel balls 11 become larger, enabling the fixing pin 8 to be pulled. At this time, the fixing pin 8 is pulled, causing the fixing pin 8 to drive the limit block 10 to move, so that the limit block 10 disengages from the inside of the limit groove 9, thereby applying force to the isolation column 5, causing the isolation column 5 to rotate, driving the rotating shaft 4 to rotate by 90 degrees, so as to clean the contact end faces between the food machinery and the bearing, reduce the growth of bacteria, and increase the cleanliness of the food machinery during use. After the cleaning is completed, the isolation column 5 is rotated so that the roller 29 at the other end of the isolation column 5 abuts against the surface of the food machinery. Then, the fixing pin 8 is pushed. The fixing pin 8 presses the steel balls 11, causing the steel balls 11 to move inside the receiving groove. When the shank of the fixing pin 8 contacts the steel balls 11, the steel balls 11 expand outward. When it is necessary to pull the fixing pin 8 outward, the steel balls 11 need to move to the right side of the tapered outer sleeve 6 and expand outward, but due to the blocking force of the tapered inner wall of the tapered outer sleeve 6, the steel balls 11 cannot expand outward. Thus, the limit block 10 is driven by the fixing pin 8 to insert into the limit groove 9 to limit the rotating shaft 4 and prevent the rotating shaft 4 from rotating, thereby being able to avoid direct contact between the bearing and the food machinery and reducing the cleaning difficulty between the end faces of the bearing and the food machinery.

[0048] When installing this bearing, align the installation hole 19 with the reserved hole on the mechanical equipment, and screw the installation bolt into the corresponding position of the installation hole 19 and the reserved hole to install this bearing. When it is necessary to change the installation position, apply force to the telescopic column 15, causing the telescopic column 15 to drive the support shaft to rotate and drive the first gear 17 to rotate. The first gear 17 meshes with the second gear 18, so that a certain force needs to be applied to the telescopic column 15 to rotate. Rotate the mounting plate 16 to a position parallel to the horizontal plane, and by adjusting the length of the telescopic column 15, make the bearing located at the precise position, and then install this bearing, so that different installation directions can be selected according to the actual installation requirements of the food machinery.

[0049] When the ball 20 rotates in the inner ring 2 of the bearing, the ball 20 contacts the arc-shaped plate 24. As the ball 20 contacts the arc-shaped plate 24, it squeezes the arc-shaped plate 24, causing the piston rod 23 to move upward. The piston disk 22 drives the piston rod 23 to move upward, causing the piston disk 22 to move upward, applying wind force to the heat dissipation cavity. When the ball 20 separates from the surface of the arc-shaped plate 24, the second spring 25 drives the arc-shaped plate 24 to reset. The pressure below the piston disk 22 reaches equilibrium through the balance pipe. The heat generated when the bearing is in use is discharged from the heat dissipation cavity, and the air flow rate is increased by applying pressure, thereby increasing the effect of heat dissipation and improving the service life of the bearing.

[0050] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
