[0030] Example 1

[0031] Reference Figure 1 to Figure 7 , which is the first embodiment of the present invention, and provides a belt conveyor, which includes a support frame 100, a plurality of rollers 200 arranged at the upper end of the support frame 100, an electric drive roller 300 arranged at both ends of the support frame 100, and a belt;

[0032] The roller 200 includes a mounting plate 201, a support plate 202 arranged on the upper end of the mounting plate 201, a roller frame 203 arranged on the upper end of the support plate 202, a roller 204 arranged inside the roller frame 203, and a correction component 205 arranged on one side of the roller frame 203.

[0033] Furthermore, the mounting plate 201 includes a fixing tube 201a disposed at the center of its surface, a pair of arc grooves 201b penetrating through both sides of the fixing tube 201a, and a dovetail bar 201c disposed on one side of the mounting plate 201; the dovetail bar 201c is distributed axially along the mounting plate 201.

[0034] Furthermore, the support plate 202 includes a pair of hinge seats 202a disposed on both sides of its upper surface, a fixing column 202b disposed at the bottom center of the support plate 202, and a pair of travel rods 202c disposed on both sides of the fixing column 202b.

[0035] Furthermore, the roller support frame 203 includes a pair of hinged columns 203a disposed on both sides thereof.

[0036] Furthermore, the correction component 205 includes a worm wheel 205a arranged on one side of the hinge column 203a, a worm 205b arranged on one side of the worm wheel 205a, a driving rod 205c sleeved inside the worm 205b, a driving disk 205d sleeved on the bottom of the worm 205b, a slider 205e arranged at the bottom of the driving disk 205d, and a spring 205f sleeved on the top of the driving rod 205c.

[0037] Furthermore, the worm 205b completely penetrates the surface of the support plate 202 and is movably connected to the driving disc 205d.

[0038] Furthermore, the worm 205b includes a first ring 205b-1 disposed at the bottom thereof, and a first conical tooth surface 205b-2 disposed at the bottom of the cavity of the worm 205b.

[0039] Furthermore, the driving rod 205c includes a pair of second conical tooth surfaces 205c-1 arranged at the bottom thereof, and a spring seat 205c-2 arranged on the outer wall of the other end of the driving rod 205c.

[0040] Furthermore, the driving disk 205d includes a limiting cylinder 205d-1 arranged on its upper end surface, a second ring 205d-2 arranged at the opening of the limiting cylinder 205d-1, a third conical tooth surface 205d-3 arranged at the bottom of the limiting cylinder 205d-1 cavity, and a vortex strip 205d-4 arranged on the lower end surface of the driving disk 205d.

[0041] Furthermore, the slider 205e includes a dovetail groove 205e-1 disposed at the bottom thereof, and a vortex groove 205e-2 disposed at the top of the slider 205e.

[0042] It should be noted that the support frame 100 is used to fix and install the rollers 200 and the electric drive rollers 300. Generally, the electric drive rollers 300 are used to drive the belt to move, while the rollers 200 are used to support the belt. The roller 200 array is fixed between the electric drive rollers 300 and is fixedly connected to the support frame 100 through the mounting plate 201.

[0043] Preferably, a fixing cylinder 201a is fixed at the center of the surface of the mounting plate 201, and a fixing column 202b can be accommodated inside the fixing cylinder 201a, so that the support plate 202 can rotate around the fixing cylinder 201a as the axis. It should be noted that a limiting ring is provided at the opening of the fixing cylinder 201a for limiting one end of the fixing column 202b to prevent the support plate 202 from falling off the mounting plate 201.

[0044] A pair of arc grooves 201b are provided at both ends of the surface of the mounting plate 201. The arc grooves 201b are symmetrically distributed on both sides of the fixed cylinder 201a with the fixed cylinder 201a as the center, and the travel rod 202c is inserted into the corresponding arc groove 201b. Since the arc length of the arc groove 201b is limited, the rotation angle of the support plate 202 is limited, and this rotation can be used for belt deviation correction.

[0045] Preferably, a pair of symmetrically distributed hinged seats 202a are fixed at both ends of the upper surface of the support plate 202, and the hinged columns 203a at both ends of the roller frame 203 simultaneously penetrate the hinged seats 202a on the corresponding sides, and the hinged seats 202a and the hinged columns 203a are movably connected, so the roller frame 203 can be turned over with the hinged columns 203a as the axis, which can be used for quick maintenance of the roller 200. In addition, a worm gear 205a is fixed on the hinged column 203a on the side with the dovetail bar 201c, and the roller frame 203 can be turned over by rotating the worm gear 205a.

[0046] Preferably, three rollers 204 are fixed on the roller support frame 203 for supporting the belt.

[0047] Preferably, a dovetail bar 201c is fixed on one side of the mounting plate 201. The dovetail bar 201c extends along the axis of the mounting plate 201 and can cooperate with the dovetail groove 205e-1 at the bottom of the slider 205e, so that the slider 205e can move along the dovetail bar 201c. It should be noted that the slider 205e and the dovetail bar 201c are in a vertical relationship.

[0048] Preferably, the deviation correction component 205 is arranged on the side with the worm wheel 205a. The end of the worm 205b without screw thread completely penetrates the support plate 202, and the two are movably connected, and the side with screw thread, near the support plate 202, is provided with a plane to prevent the worm 205b from falling off the support plate 202, and the opening at the bottom of the worm wheel 205a is fixed with a first ring 205b-1, and the driving plate 205d, which is also fixed with a second ring 205d-2, can be sleeved on the first ring 205b-1 of the worm wheel 205a without falling off, and the first ring 205b-1 and the second ring 205d-2 are mutually limited.

[0049] A first bevel tooth surface 205b-2 is provided inside the lower end surface of the worm 205b.

[0050] Preferably, a limiting cylinder 205d-1 is fixed on the upper end surface of the driving disk 205d, and an inwardly buckled second ring 205d-2 is fixed at the opening of the limiting cylinder 205d-1 to form a mutual limiting effect with the worm 205b. A third conical tooth surface 205d-3 is provided at the bottom of the cavity of the limiting cylinder 205d-1, and the third conical tooth surface 205d-3 is symmetrical to the first conical tooth surface 205b-2.

[0051] A vortex bar 205d-4 is also fixed on the lower end surface of the driving disk 205d, which can cooperate with a number of vortex grooves 205e-2 on the upper surface of the slider 205e. It should be noted that the slider 205e always points to the center of the driving disk 205d and is away from the center.

[0052] It should be noted that when the driving disk 205d rotates, the driving disk 205d will move under the action of the vortex groove 205e-2 and the vortex bar 205d-4. Since the support plate 202 can only make circular motion, the lateral movement of the slider 205e can prevent the motion interference when the support plate 202 rotates, but ensures the movement of the driving disk 205d, that is, the support plate 202 can rotate and can achieve self-locking.

[0053] Preferably, the driving rod 205c completely penetrates the interior of the worm 205b, and a round block consisting of two symmetrically distributed second conical tooth surfaces 205c-1 is fixed to the driving rod 205c, and the round block is located between the first conical tooth surface 205b-2 and the third conical tooth surface 205d-3. Since a spring seat 205c-2 is also fixed to the outer wall of the top of the driving rod 205c, and the two ends of the spring 205f are respectively limited by the upper end surface of the worm 205b and the spring seat 205c-2, the driving rod 205c is lifted up by the spring 205f, and in the absence of external interference, the first conical tooth surface 205b-2 first meshes with the second conical tooth surface 205c-1 at a slightly upper position.

[0054] When a person rotates the drive rod 205c by a wrench or an electric wrench, the worm 205b can be driven to rotate, and the worm wheel 205a drives the roller frame 203 to rotate, so that the roller frame 203 can be tilted and easily repaired. When the person presses down and rotates the drive rod 205c, the third bevel tooth surface 205d-3 meshes with the lower second bevel tooth surface 205c-1, and the drive disc 205d rotates, thereby driving the support plate 202 to deflect in the circumferential direction, which is used to correct the belt, and the corresponding slider 205e will also slide sideways. The above two processes can be self-locking, that is, when external forces interfere with the support plate 202 or the roller frame 203, they will not be affected by malfunction.

[0055] In summary, this design can realize the flipping and maintenance of the roller frame 203 through the operation of the driving rod 205c, and can rotate and correct the roller frame 203 when the belt is offset during operation. The transmission of the above operations is unidirectional, and the overall stability and reliability of the roller 200 are high.

[0056] It is important to note that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
