Description

Technical Field

[0001] This invention relates to the field of bearing production equipment technology, and in particular to a belt feeding device for conveying bearing races. Background Technology

[0002] Belt conveyor for bearing rings is mainly used to transport bearing rings from one place to another. Through the rotation of the drive device, the conveyor belt can transport the bearing rings. Belt conveyor can continuously transport a large number of workpieces, so it is suitable for large-scale production. During use, attention should be paid to the maintenance of the equipment to ensure its normal operation and extend its service life.

[0003] Traditional existing technical solutions have the following drawbacks: when belt conveyor transports bearing rings, the excessive mechanical transmission of the equipment itself will cause vibration. During the transport of bearing rings, they will fall off due to vibration, requiring the equipment to transport them repeatedly, which affects the quantity and efficiency of the transport, resulting in low equipment efficiency. Furthermore, it is inconvenient to screen bearing rings that do not meet the size requirements, making it impractical. Summary of the Invention

[0004] The purpose of this invention is to provide a belt feeding device for conveying rings, thereby solving the problem of low conveying efficiency in existing belt feeding devices for conveying rings.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a belt feeding device for conveying rings, comprising a base and a plate conveyor belt. A support is fixedly connected to the top of the base, and rollers are fixedly installed at both the top and bottom of the support. A servo motor is installed on one side of each roller. A plate conveyor belt is fixedly connected to the outside of the rollers. A finished product box is provided on the top of the base at one end of the plate conveyor belt, and a defective product box is provided on one side of the finished product box. A feeding chute is fixedly connected to one side of the support, and a screening structure is fixedly connected to the top of the feeding chute. A left support plate is fixedly connected to one side of the outer side of the plate conveyor belt. The other side of the outer side of the plate conveyor belt... Each support is fixedly connected to a right support plate. A sliding groove is provided on one side of one end of the support. A limiting mechanism is provided inside the left support plate. The limiting mechanism includes an electromagnetic groove, a conductive head, a spring, a left electromagnetic attraction block, a right electromagnetic attraction block, a conductive post, and a gasket. The electromagnetic groove is located inside the sliding groove. A left electromagnetic attraction block is fixedly connected inside the left support plate on one side of the electromagnetic groove. A conductive post is movably connected inside the left electromagnetic attraction block. A conductive head is fixedly connected to one side of the conductive post. A spring is provided outside the conductive head. A right electromagnetic attraction block is fixedly connected inside the right support plate on one side of the conductive post. Gaskets are provided on the outer walls of both the right and left support plates at one end of the right electromagnetic attraction block.

[0006] Preferably, the screening structure includes an upper slot, an upper baffle, a lower slot, and a lower baffle. The upper slot is fixed to the top of the feeding trough, and the lower slot is fixedly connected to the top of the feeding trough at the bottom of the upper slot.

[0007] Preferably, upper baffles are provided at the bottom of both ends of the upper slot, and lower baffles are provided at the top of both ends of the lower slot. The cooperation between the upper and lower baffles enables the qualified bearing to be rolled and conveyed to one side.

[0008] Preferably, the height between the upper and lower retaining grooves is greater than the outer diameter of the bearing race, and the height between the upper and lower baffles is less than the outer diameter of the bearing race. The heights of the upper baffles are varied. When the outer diameter of the bearing is too small, the upper baffle cannot contact and support it, causing the defective bearing to fall off, thus achieving screening.

[0009] Preferably, the bottom of the feeding chute extends to the top of the defective product box, and the bottom of the plate conveyor belt is located inside the finished product box. Bearings with unqualified outer diameters slide into the defective product box through the feeding chute, which also facilitates the conveying of bearings by the plate conveyor belt.

[0010] Preferably, the right support plate and the left support plate are inclined, and the right support plate, the left support plate, and the lower slot are aligned when they are joined. This allows the bearing to roll to one side under its own weight for feeding.

[0011] Preferably, the length between the conductive head and the conductive post is greater than the length of the left support plate. The two ends of the spring are fixedly connected to the conductive head and the left support plate, respectively. One side of the conductive head is spherical. By pressing the conductive head, the conductive post is pushed into the right electromagnetic attraction block, and the spring can push the conductive head and conductive post back to their original positions.

[0012] Preferably, the outer diameter of the conductive post is equal to the inner diameter of the left and right electromagnetic attracting blocks, and a sliding structure is formed between the electromagnetic groove and the conductive head. The bottom of the groove is arc-shaped. The arc-shaped bottom of the groove facilitates the sliding operation of the conductive head, and the conductive post fits tightly with the interior of the left and right electromagnetic attracting blocks, facilitating electrical connection.

[0013] Preferably, the plate conveyor belt and the support form a rotating structure. The right support plate and the left support plate are fixed to the outer sides of two adjacent plates of the plate conveyor belt, and the distance between the adjacent right support plate and the left support plate is greater than the outer diameter of the bearing race. This enables the plate conveyor belt to operate normally and allows the right support plate and the left support plate to support and transport the bearing.

[0014] The belt feeding device for conveying rings provided by this invention has the following advantages:

[0015] By setting a limiting mechanism, when the plate conveyor belt is operating, the bearing is driven to engage with the left and right support plates. When rotating to the chute, the conductive head is squeezed, causing the conductive column to move to one side into the right electromagnetic attraction block. After the conductive head slides into the electromagnetic groove and is energized, the current is transmitted to the left and right electromagnetic attraction blocks through the conductive column. After the left and right electromagnetic attraction blocks are energized and opened, the bearing is attracted to the left and right support plates. When the conductive head slides to the top of the chute, the spring drives the conductive column to disengage from the right electromagnetic attraction block through tension. After the conductive head slides out of the electromagnetic groove, the power is cut off, the left and right electromagnetic attraction blocks stop attracting, and the bearing is unloaded from one side. This realizes the function of limiting the bearing rings during the conveying process of the belt feeding equipment used for ring conveying, preventing the bearing rings from falling off midway due to vibration, and improving the working efficiency of the equipment.

[0016] By incorporating a screening structure, when the left and right support plates rotate to align with the lower slot, the bearing rings, through their own pressure and the inclined angle of the support, cause them to roll along the lower slot. Due to the cooperation between the upper and lower baffles, bearings with acceptable outer diameters roll to one side. When the outer diameter of the bearing is smaller, the upper baffle cannot engage with the bearing, and it loses support and falls into the defective product box along the feed chute due to gravity. This makes the belt feeding equipment used for conveying bearing rings easier to screen for defective bearing rings, simplifying operation and saving labor and finished products.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-9The present invention provides a belt feeding device for conveying rings, comprising a base 3 and a plate conveyor belt 11. A bracket 9 is fixedly connected to the top of the base 3, and rollers 12 are fixedly installed on both the top and bottom of the bracket 9. A servo motor 10 is installed on one side of the rollers 12. The plate conveyor belt 11 is fixedly connected to the outside of the rollers 12. A finished product box 5 is provided on the top of the base 3 at one end of the plate conveyor belt 11, and a defective product box 4 is provided on one side of the finished product box 5. A feeding chute 2 is fixedly connected to one side of the bracket 9, and the bottom of the feeding chute 2 extends to the top of the defective product box 4. The bottom of the plate conveyor belt 11 is located inside the finished product box 5. A left support plate 7 is fixedly connected to the outside of the plate conveyor belt 11. A limiting mechanism 8 is provided inside the left support plate 7. The limiting mechanism 8 includes an electromagnetic groove 801, a conductive head 802, a spring 803, a left electromagnetic attraction block 804, a right electromagnetic attraction block 805, a conductive post 806, and a gasket 807. Electromagnetic groove 801 is located inside the slide 13. A left electromagnetic attraction block 804 is fixedly connected inside the left support plate 7 on one side of electromagnetic groove 801. A conductive post 806 is movably connected inside the left electromagnetic attraction block 804. A conductive head 802 is fixedly connected to one side of the conductive post 806, and a spring 803 is provided outside the conductive head 802. A right electromagnetic attraction block 805 is fixedly connected inside the right support plate 6 on one side of the conductive post 806. The right support plate 6 at one end of the right electromagnetic attraction block 805... Both the outer wall of the left support plate 7 and the outer wall of the left support plate 7 are provided with gaskets 807. The length between the conductive head 802 and the conductive post 806 is greater than the length of the left support plate 7. The two ends of the spring 803 are fixedly connected to the conductive head 802 and the left support plate 7 respectively. One side of the conductive head 802 is spherical. The outer diameter of the conductive post 806 is equal to the inner diameter of the left electromagnetic attraction block 804 and the right electromagnetic attraction block 805. The electromagnetic groove 801 and the conductive head 802 form a sliding structure. The bottom of the groove 13 is arc-shaped.

[0029] Reference Figure 6 , Figure 8 and Figure 9As shown, bearing rings are placed inside the finished product box 5. The servo motor 10 is started, driving the plate conveyor belt 11 to rotate via the roller 12. As the plate conveyor belt 11 rotates, the bearing engages with the left support plate 7 and the right support plate 6. When the left support plate 7 rotates to the slide groove 13, the conductive head 802 is squeezed, pushing the conductive column 806 to one side into the right electromagnetic attraction block 805. After the conductive head 802 slides along the slide groove 13 into the electromagnetic groove 801 and is energized, the current is transmitted through the conductive column 806 to the left electromagnetic attraction block 804 and the right electromagnetic attraction block 805. When the magnetic attraction block 805, the left electromagnetic attraction block 804, and the right electromagnetic attraction block 805 are energized, they open and attract the bearing onto the left support plate 7 and the right support plate 6. Due to the gasket 807, insulation is achieved. When the conductive head 802 slides to the top of the slide groove 13, it disengages from the electromagnetic groove 801 and the power is cut off. The left electromagnetic attraction block 804 and the right electromagnetic attraction block 805 stop attracting the bearing, and the bearing rolls out from one side. The spring 803 drives the conductive column 806 to slide out of the right electromagnetic attraction block 805 through tension, so as not to affect the operation of the plate conveyor belt 11.

[0030] A screening structure 1 is fixedly connected to the top of the feeding trough 2. The screening structure 1 includes an upper slot 101, an upper baffle 102, a lower slot 103, and a lower baffle 104. The upper slot 101 is fixed to the top of the feeding trough 2. The lower slot 103 is fixedly connected to the top of the feeding trough 2 at the bottom of the upper slot 101. Upper baffles 102 are provided at the bottom of both ends of the upper slot 101, and lower baffles 104 are provided at the top of both ends of the lower slot 103. The height between the upper slot 101 and the lower slot 103 is greater than the outer diameter of the bearing ring. The height between the upper baffle 102 and the lower baffle 104 is... The height between them is less than the outer diameter of the bearing ring. The height of the upper baffle 102 is not uniform. The other side of the plate conveyor belt 11 is fixedly connected to the right support plate 6. The plate conveyor belt 11 and the bracket 9 form a rotating structure. The right support plate 6 and the left support plate 7 are fixed to the outer sides of two adjacent plates of the plate conveyor belt 11. The adjacent distance between the right support plate 6 and the left support plate 7 is greater than the outer diameter of the bearing ring. The right support plate 6 and the left support plate 7 are inclined. When the right support plate 6, the left support plate 7 and the lower slot 103 are combined, their positions are relatively aligned. A sliding groove 13 is provided on one side of one end of the bracket 9.

[0031] Reference Figure 3 and Figure 7 As shown, when the left support plate 7 and the right support plate 6 are rotated to align with the lower slot 103, the bearing rings roll along the lower slot 103 due to their own pressure and the tilt angle of the support. Due to the cooperation between the upper baffle 102 and the lower baffle 104, bearings with qualified outer diameters roll to one side. When the outer diameter of the bearing is small, the upper baffle 102 cannot engage with the bearing, and it loses support and falls into the defective product box 4 along the feed chute 2 due to gravity, thus making it easier for workers to screen and remove the bearings.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
