DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1: Please refer to Figure 1-Figure 7The present invention provides a technical solution: a mechanical bearing for food machinery and equipment, comprising 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 is rotatably penetrated through the outer surface of the connecting seat 3, a spacer 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 is movably penetrated through the outer surface of the conical outer sleeve 6, and three accommodating grooves are opened on the outer surface of the conical inner sleeve 7 in a circumferential array, and the three accommodating grooves are arranged on the outer surface of the conical inner sleeve 7. The inside of each groove is provided with a steel ball 11, the fixing needle 8 is located at one end of the conical outer sleeve 6 close to the rotating shaft 4 and is fixedly connected to a connecting rod, the other end of the connecting rod is fixedly connected to a limiting block 10, a limiting groove 9 is provided on the outer surface of the rotating shaft 4, and a third spring 28 is fixedly connected to the inside of the limiting groove 9. Specifically, the bearing and the food machinery are blocked by the isolation column 5 to prevent the bearing from directly contacting the surface of the food machinery, so that the conical inner sleeve 7 moves, driving the steel ball 11 to move, and after the steel ball 11 moves, the gap between the multiple steel balls 11 becomes larger, so that the fixing needle 8 can be pulled out, at this time, the fixing needle 8 is pulled, so that the fixing needle 8 drives the limit block 10 to move, so that the limit block 10 is separated from the inside of the limit groove 9, thereby applying force to the isolation column 5, so that the isolation column 5 rotates, driving the rotating shaft 4 to rotate ninety degrees, so as to clean the contact end surface between the food machinery and the bearing, reduce bacterial breeding, and increase the cleanliness of the food machinery when in use. After cleaning, 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, and then the fixing needle 8 is pushed, and the fixing needle 8 squeezes the steel ball 11, so that The steel ball 11 moves inside the accommodating groove. When the needle rod of the fixed needle 8 contacts the steel ball 11, the steel ball 11 expands outward. When the fixed needle 8 needs to be pulled outward, the steel ball 11 needs to move to the left side of the tapered outer sleeve 6 and expand outward. However, it is blocked by the tapered inner wall of the tapered outer sleeve 6, so that the steel ball 11 cannot expand outward. Therefore, the limiting block 10 is driven by the fixed needle 8 to insert into the limiting groove 9, so as to limit the rotating shaft 4 and prevent the rotating shaft 4 from rotating. This can avoid direct contact between the bearing and the food machinery, and reduce the difficulty of cleaning the bearing and the end face of the food machinery.

[0022] In this embodiment, a first spring 12 is fixedly connected to the inner wall of the conical outer sleeve 6, and 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 top outer surface of the conical inner sleeve 7. A slide groove is provided on the outer surface of the conical outer sleeve 6, and the lever 13 is movably connected to the inside of the slide groove. Specifically, when it is necessary to clean the bearing and the end face of the food machinery, the lever 13 is pulled to move the lever 13 in the slide groove, thereby moving the conical inner sleeve 7 and deforming the first spring 12.

[0023] In this embodiment, a movable column 27 is movably inserted inside the isolation column 5, a third spring 28 is fixedly connected inside the isolation column 5, the other end of the third spring 28 is fixedly connected to the movable column 27, and a roller 29 is installed on the other end of the movable column 27. Specifically, when the isolation column 5 is rotated, when the roller 29 contacts the surface of the food machinery, the third spring 28 is compressed, and under the action of 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 column 5.

[0024] In this embodiment, a connecting disk is fixedly connected to the outer surface of the fixing needle 8, and a fourth spring is fixedly connected between the connecting disk and the conical sleeve 6. The fourth spring is sleeved on the outer surface of the fixing needle 8. Specifically, when the steel ball 11 moves to provide a moving channel for the fixing needle 8, the fourth spring is reset, and the fourth spring drives the fixing needle 8 to reset.

[0025] In the specific implementation process, the bearing is installed on the food machinery, and the isolation column 5 is used to block the bearing and the food machinery to prevent the bearing from directly contacting the surface of the food machinery. When the bearing and the end face of the food machinery need to be cleaned, the lever 13 is pulled to move the conical inner sleeve 7, driving the steel ball 11 to move. After the steel ball 11 moves, the gap between the multiple steel balls 11 becomes larger, so that the fixing needle 8 can be pulled out. At this time, the fixing needle 8 is pulled to make the fixing needle 8 drive the limit block 10 to move, so that the limit block 10 is separated from the inside of the limit groove 9, thereby applying force to the isolation column 5, so that the isolation column 5 rotates, driving the rotating shaft 4 to rotate ninety degrees, thereby cleaning the contact end face between the food machinery and the bearing, reducing bacterial growth, and increasing the food machinery in use. To improve the cleanliness during use, after cleaning, 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 fixed needle 8. The fixed needle 8 squeezes the steel ball 11, so that the steel ball 11 moves inside the accommodating groove. When the needle rod of the fixed needle 8 contacts the steel ball 11, the steel ball 11 expands outward. When the fixed needle 8 needs to be pulled outward, the steel ball 11 needs to move to the left side of the conical sleeve 6 and expand outward, but it is blocked by the conical inner wall of the conical sleeve 6, so that the steel ball 11 cannot expand outward, so that the limit block 10 is driven by the fixed needle 8 to insert into the limit groove 9, 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 difficulty of cleaning between the bearing and the end face of the food machinery.

[0026] Embodiment 2: Please refer to Figure 1-Figure 2 , Figure 4 and Figure 8The present invention provides a technical solution: the left and right outer surfaces of the bearing outer ring 1 are fixedly connected with a rotating seat 14, the outer surface of the rotating seat 14 is rotatably penetrated by a support shaft, the outer surface of the support shaft is fixedly sleeved with a telescopic column 15, the other end of the telescopic column 15 is fixedly connected with a mounting plate 16, and the outer surface of the mounting plate 16 is provided with a mounting hole 19. Specifically, when installing the bearing, align the mounting hole 19 with the reserved hole on the mechanical equipment, and screw the mounting bolt into the mounting hole 19 corresponding to the reserved hole to install the bearing. When the installation position needs to be changed, force is applied to the telescopic column 15, so that the telescopic column 15 drives the support shaft to rotate, and the mounting plate 16 is rotated to a position parallel to the horizontal plane.

[0027] 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, and the first gear 17 is movably meshed with the outer surfaces of the second gear 18. Specifically, when the telescopic column 15 drives the support shaft to rotate, the first gear 17 is driven to rotate, and the first gear 17 is meshed with the second gear 18, so that the telescopic column 15 needs to apply a certain force to rotate.

[0028] In this embodiment, the telescopic column 15 includes a fixed column and an adjusting column. The outer surfaces of the fixed column and the adjusting column are provided with screw holes. The number of screw holes on the surface of the adjusting column is several and they are arranged in a linear array. The screw holes corresponding to the fixed column and the adjusting column are threadedly connected with an adjusting handwheel. Specifically, by adjusting the position of the adjusting column in the fixed column and making the corresponding screw holes correspond to each other, the adjusting handwheel is screwed into the corresponding screw hole to limit the fixed column and the adjusting column, thereby adjusting the overall length of the telescopic column 15.

[0029] In the specific implementation process, when installing the bearing, align the mounting hole 19 with the reserved hole on the mechanical equipment, and screw the mounting bolt into the mounting hole 19 corresponding to the reserved hole to install the bearing. When the installation position needs to be changed, force is applied 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 is meshed with the second gear 18, so that the telescopic column 15 needs to apply a certain force to rotate. The mounting plate 16 is rotated to a position parallel to the horizontal plane, and the bearing is located at a precise position by adjusting the length of the telescopic column 15. Then, the bearing is installed, so that different installation directions can be selected according to the actual installation requirements of the food machinery.

[0030] Embodiment 3: Please refer to Figure 9-10The present invention provides a technical solution: a plurality of balls 20 are arranged between the bearing outer ring 1 and the bearing inner ring 2, a heat dissipation cavity is opened inside the bearing outer ring 1, a plurality of ventilation holes 26 are opened in a circumferential array on the outer surface of the bearing outer ring 1, and the ventilation holes 26 extend to the inside of the heat dissipation cavity, a piston cylinder 21 is fixedly connected to the outer surface of the bearing outer ring 1, a piston disk 22 is movably connected inside the piston cylinder 21, a piston rod 23 is fixedly connected to the bottom outer surface of the piston disk 22, and an arc plate 24 is fixedly connected to the bottom outer surface of the piston rod 23. Specifically, when the bearing inner ring 2 causes the ball 20 to rotate, the ball 20 contacts the arc plate 24, and as the ball 20 contacts the arc plate 24, the arc plate 24 is squeezed, so that the piston rod 23 moves upward, and the piston plate drives the piston rod 23 to move upward, so that the piston disk 22 moves upward, and wind force is applied to the heat dissipation cavity.

[0031] In this embodiment, the outer surface of the piston cylinder 21 is fixedly connected to a balance pipe, and a one-way valve is installed inside the balance pipe. The flow direction of the one-way valve is from the inside of the piston cylinder 21 to the outside of the piston cylinder 21. Specifically, when the ball 20 is separated from the surface of the arc plate 24, the pressure under the piston plate is balanced through the balance pipe.

[0032] In this embodiment, a connecting plate is fixedly connected to the interior of the piston cylinder 21, and the piston rod 23 movably passes through the outer surface of the connecting plate. A second spring 25 is fixedly connected between the connecting plate and the piston plate 22. Specifically, when the piston plate 22 moves upward, the second spring 25 is deformed. When the ball 20 is separated from the surface of the arc plate 24, the second spring 25 drives the arc plate 24 to reset.

[0033] During the specific implementation process, when the inner ring 2 of the bearing makes the ball 20 rotate, the ball 20 contacts the arc plate 24. As the ball 20 contacts the arc plate 24, the arc plate 24 is squeezed, so that the piston rod 23 moves upward, and the piston plate drives the piston rod 23 to move upward, so that the piston disc 22 moves upward, and wind force is applied to the heat dissipation cavity. When the ball 20 is separated from the surface of the arc plate 24, the second spring 25 drives the arc plate 24 to reset, and the pressure under the piston plate is balanced by the balance pipe. The heat generated by the bearing during use is discharged from the heat dissipation cavity, and the air flow rate is increased by applying pressure, thereby increasing the heat discharge effect and improving the service life of the bearing.

[0034] Working principle: When the present invention is used, the bearing is installed on the food machinery, and the isolation column 5 is used to block the bearing and the food machinery to prevent the bearing from directly contacting the surface of the food machinery. When the bearing and the end face of the food machinery need to be cleaned, the lever 13 is pulled to move the conical inner sleeve 7, driving the steel ball 11 to move. After the steel ball 11 moves, the gap between the plurality of steel balls 11 becomes larger, so that the fixing needle 8 can be pulled out. At this time, the fixing needle 8 is pulled to drive the limit block 10 to move, so that the limit block 10 is separated from the inside of the limit groove 9, thereby applying force to the isolation column 5, so that the isolation column 5 rotates, driving the rotating shaft 4 to rotate ninety degrees, thereby cleaning the contact end face between the food machinery and the bearing, reducing bacterial growth, and increasing the food machinery Regarding the cleanliness during use, after cleaning, 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 fixed needle 8. The fixed needle 8 squeezes the steel ball 11, so that the steel ball 11 moves inside the accommodating groove. When the needle rod of the fixed needle 8 contacts the steel ball 11, the steel ball 11 expands outward. When the fixed needle 8 needs to be pulled outward, the steel ball 11 needs to move to the left side of the conical sleeve 6 and expand outward, but it is blocked by the conical inner wall of the conical sleeve 6, so that the steel ball 11 cannot expand outward, so that the limiting block 10 is inserted into the limiting groove 9 through the fixed needle 8 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 difficulty of cleaning between the bearing and the end face of the food machinery.

[0035] When installing the bearing, align the mounting hole 19 with the reserved hole on the mechanical equipment, and screw the mounting bolt into the mounting hole 19 corresponding to the reserved hole to install the bearing. When the installation position needs to be changed, 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 is meshed with the second gear 18, so that the telescopic column 15 needs to apply a certain force to rotate. The mounting plate 16 is rotated to a position parallel to the horizontal plane, and the bearing is located at a precise position by adjusting the length of the telescopic column 15. Then, the bearing is installed, so that different installation directions can be selected according to the actual installation requirements of the food machinery.

[0036] When the inner ring 2 of the bearing makes the ball 20 rotate, the ball 20 contacts the arc plate 24. As the ball 20 contacts the arc plate 24, the arc plate 24 is squeezed, causing the piston rod 23 to move upward. The piston plate drives the piston rod 23 to move upward, causing the piston disc 22 to move upward, applying wind force to the heat dissipation cavity. When the ball 20 is separated from the surface of the arc plate 24, the second spring 25 drives the arc plate 24 to reset. The pressure under the piston plate is balanced by the balance pipe. The heat generated by the bearing during use is discharged from the heat dissipation cavity, and the air flow rate is increased by applying pressure, thereby increasing the heat discharge effect and improving the service life of the bearing.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
