The traction force is unevenly distributed, which can easily cause the rubber conveyor belt to break or crack on the side, thereby reducing the service life of the rubber conveyor belt.

DETAILED DESCRIPTION

[0031] The present invention is described in detail below, and the technical solutions in the embodiments of the present invention are clearly and completely described. 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.

[0032] The present invention provides a cut-resistant rubber conveyor belt through improvement. The technical solution of the present invention is:

[0033] like Figures 1 to 8 As shown, an embodiment of the present invention provides a cut-resistant rubber conveyor belt, comprising two side plates 1, two rollers 2 are rotatably connected between the two side plates 1, belt rollers 3 are fixed on the outer sides of the two rollers 2, and rubber conveyor belts 5 are transmission-connected on the outer sides of the two belt rollers 3, one end of one of the side plates 1 is installed with a motor 4, and the driving end of the motor 4 is fixedly connected to one end of one of the rollers 2, and the motor 4 is started, and the motor 4 drives a roller 2 connected thereto to rotate, and this roller 2 drives the belt roller 3 on its outer side to rotate, and this belt roller 3 drives the rubber conveyor belt 5 and the other belt roller 3 to rotate synchronously, and the two rollers 2 Two traction mechanisms are symmetrically arranged between the two ends and the two side plates 1, and multiple buffer support mechanisms are also arranged between the two roller shafts 2; the traction mechanism includes two pulleys 6 fixed at one end of the two roller shafts 2, and a guide slide groove 11 opened on one side of the side plate 1, the outer sides of the two pulleys 6 are connected to the synchronous belt 7, and multiple fixed sleeves 105 are fixed inside the synchronous belt 7, and a sliding sleeve 106 is slidably inserted on the inner side of each fixed sleeve 105, and a clamping mechanism is arranged on the inner side and both ends of each sliding sleeve 106, and elastic baffles 10 are arranged on the outer side of the rubber conveyor belt 5 at the positions of both sides;

[0034] The elastic blocking piece 10 can block the material being transported on the rubber conveyor belt 5 to prevent the material from spilling from the side of the rubber conveyor belt 5 .

[0035] Furthermore, the clamping mechanism includes a rotating shaft 107 that penetrates and is rotatably connected to the inner side of the sliding sleeve 106 and a housing 101 that is fixed to one end of the sliding sleeve 106. Two fixed guide rods 102 are fixed to the inner side of the housing 101. Two sliders 103 are slidably sleeved at both ends of the outer sides of the two fixed guide rods 102. A clamping plate 104 is fixed to one side of the two sliders 103. Two rotating rods 108 are symmetrically fixed to one end of the rotating shaft 107. One end of the two rotating rods 108 is rotatably connected to the other side of the two sliders 103 through a connecting rod 109.

[0036] The inner and outer sides of the rubber conveyor belt 5 are clamped by the clamping plate 104 in the clamping mechanism, so that the traction force of the synchronous belt 7 can be transmitted to the rubber conveyor belt 5, so that the traction force acting on the upper side of the rubber conveyor belt 5 is more evenly distributed, preventing the two ends of the rubber conveyor belt 5 from being subjected to excessive concentration of traction force from the two belt rollers 3, which causes the rubber conveyor belt 5 to break or cracks on the side, thereby extending the service life of the rubber conveyor belt 5.

[0037] Furthermore, a first convex ring 110 is fixed to one end of the outer side of the sliding sleeve 106 away from the housing 101, a second convex ring 111 is fixed to one end of the outer side of the rotating shaft 107 close to the first convex ring 110, a torsion spring 112 is elastically connected between the first convex ring 110 and the second convex ring 111, a reversing rod 113 is also fixed to one end of the rotating shaft 107 close to the first convex ring 110, two guide sliding shafts 114 are rotatably connected to both ends of the reversing rod 113, the first convex ring 110 and the fixed sleeve 105 are elastically connected by a reset spring 115, two movable guide rods 118 are slidably inserted in the two clamping plates 104, one end of the two movable guide rods 118 at the same height are fixed to a buffer clamping plate 119, and a buffer spring 120 is sleeved on the outer side of each movable guide rod 118;

[0038] The two guide slide shafts 114 can drive the reversing rod 113 to rotate, thereby driving the rotating shaft 107 to rotate, and the rotating shaft 107 drives the two rotating rods 108 to rotate. The two rotating rods 108 drive the two sliders 103 to move synchronously to the middle position of the shell 101 through the two connecting rods 109, thereby driving the two clamping plates 104 to merge, and the two clamping plates 104 drive the two buffer clamping plates 119 to clamp the inner and outer sides of the rubber conveyor belt 5 respectively. When the two buffer clamping plates 119 are gradually clamped on the inner and outer sides of the rubber conveyor belt 5 under the action of the two clamping plates 104, each buffer spring 120 is slowly compressed, so that the clamping force is gradually applied to the inner and outer sides of the rubber conveyor belt 5, effectively avoiding the side deformation of the rubber conveyor belt 5 caused by excessive clamping force applied instantly.

[0039] Furthermore, an extension bracket 116 is fixed to one end of the lower side of the sliding sleeve 106 close to the first convex ring 110, and one end of the extension bracket 116 is rotatably connected to a roller 117;

[0040] The roller 117 and the extension bracket 116 push the sliding sleeve 106 to move along the inner side of the fixed sleeve 105 toward the position of the rubber conveyor belt 5, so that the two clamping plates 104 are close to the side of the rubber conveyor belt 5, so that the clamping plates 104 and the side of the rubber conveyor belt 5 have a certain overlap.

[0041] Further, a guide slot 11 is provided on one side of the side plate 1 at a position corresponding to the guide slide shaft 114, an upper slot 12 and a lower slot 13 are symmetrically provided on the upper side of the guide slot 11, both ends of the upper slot 12 and the lower slot 13 are smoothly connected to the guide slot 11, a guide strip 8 is fixed on one side of the side plate 1 at a position corresponding to the roller 117, and two inclined push surfaces 9 are provided at both ends of the guide strip 8;

[0042] When the two guide slide shafts 114 slide from the inner side of the guide slide groove 11 into the inner sides of the upper slide groove 12 and the lower slide groove 13 respectively, the two guide slide shafts 114 change from the same height to different heights, thereby driving the reversing rod 113 to rotate a certain angle, thereby driving the rotating shaft 107 to rotate, and driving the two clamping plates 104 to merge;

[0043] The two inclined push surfaces 9 at both ends of the guide strip 8 can apply a lateral thrust to the roller 117, thereby pushing the sliding sleeve 106 to move along the inner side of the fixed sleeve 105 toward the position of the rubber conveyor belt 5, so that the two clamping plates 104 are close to the side of the rubber conveyor belt 5, so that the clamping plates 104 and the side of the rubber conveyor belt 5 have a certain overlapping portion.

[0044] Furthermore, the buffer support mechanism includes a square rod 201 fixed between the two side plates 1, a fixing rod 202 is arranged on the outside of the square rod 201, a rectangular hole 203 for the square rod 201 to pass through is opened inside the fixing rod 202, and a rotating cylinder 204 is rotatably connected to the outside of the fixing rod 202, and the upper side of the square rod 201 is elastically connected to the fixing rod 202 through a plurality of symmetrically arranged springs 205;

[0045] Through multiple buffer support mechanisms, when the material hits the upper side of the rubber conveyor belt 5, the instantaneous impact force can be buffered, thereby protecting the rubber conveyor belt 5 and preventing the rubber conveyor belt 5 from being broken due to excessive impact force.

[0046] Working principle: When in use, the motor 4 is started, and the motor 4 drives a roller shaft 2 connected to it to rotate, and the roller shaft 2 drives the belt roller 3 on its outer side to rotate, and the belt roller 3 drives the rubber conveyor belt 5 and another belt roller 3 to rotate synchronously, and the rubber conveyor belt 5 rotates to transport the material on its upper side;

[0047] When the two rollers 2 rotate, the pulleys 6 of the two traction mechanisms can be driven to rotate synchronously. The two pulleys 6 of each traction mechanism drive the outer synchronous belt 7 to rotate. The synchronous belt 7 drives the multiple clamping mechanisms arranged inside it to move along the moving track of the synchronous belt 7 and the rubber conveyor belt 5. The direction of the end away from the motor 4 is the conveying forward direction of the conveyor belt. Figure 1 As shown, the clamping mechanism moves with the synchronous belt 7. When the roller 117 of the clamping mechanism moves to the position of the inclined push surface 9 at one end of the guide strip 8, a lateral thrust is applied to the roller 117 under the guidance of the inclined push surface 9, so that the roller 117 and the extension bracket 116 push the sliding sleeve 106 to move along the inner side of the fixed sleeve 105 toward the position of the rubber conveyor belt 5, so that the two clamping plates 104 are close to the side of the rubber conveyor belt 5, so that the clamping plates 104 and the side of the rubber conveyor belt 5 have a certain overlap, as shown in FIG. Figure 5 As shown;

[0048] The torsion spring 112 in the clamping mechanism applies a certain torsion torque to the second convex ring 111, and the torsion torque is transmitted to the rotating shaft 107, and then transmitted to the reversing rod 113 through the rotating shaft 107, and finally transmitted to the two guide slide shafts 114. After the torsion torque is applied to the upper side of the guide slide groove 11 at one end of the conveying forward direction, the other guide slide shaft 114 applies pressure to the lower side of the guide slide groove 11. Therefore, when the two guide slide shafts 114 slide inside the guide slide groove 11, the guide slide shaft 114 at one end of the conveying forward direction is pressed against the upper side of the guide slide groove 11. The guide slide shaft 114 is always in contact with the upper side of the guide slide groove 11, and the other guide slide shaft 114 is always in contact with the lower side of the guide slide groove 11. As the synchronous belt 7 drives the clamping mechanism to continue to move, when the two guide slide shafts 114 move to the ends of the upper slide groove 12 and the lower slide groove 13, under the torsion elastic force of the torsion spring 112, one guide slide shaft 114 located in the conveying forward direction will slide into the upper slide groove 12 on the upper side due to the upward force, and the other guide slide shaft 114 will slide into the inner side of the lower slide groove 13 on the lower side due to the downward force, as shown in FIG. Figure 5 As shown, the reversing rod 113 rotates a certain angle, the reversing rod 113 drives the rotating shaft 107 to rotate a certain angle, the rotating shaft 107 drives the two rotating rods 108 to rotate, and the two rotating rods 108 drive the two sliders 103 to move synchronously to the middle position of the shell 101 through the two connecting rods 109, thereby driving the two clamping plates 104 to merge, and the two clamping plates 104 drive the two buffer clamping plates 119 to clamp the inner and outer sides of the rubber conveyor belt 5 respectively. The diameters of the pulley 6 and the belt roller 3 are equal, so the synchronous belt 7 and the rubber conveyor belt 5 can keep synchronous rotation, and when each clamping mechanism is clamped on the inner and outer sides of the rubber conveyor belt 5, it can keep synchronous movement with the rubber conveyor belt 5. The traction mechanism drives multiple clamping mechanisms to apply traction to multiple points on the side of the rubber conveyor belt 5 at the same time, so that the traction force acting on the upper side of the rubber conveyor belt 5 can be more evenly distributed, so as to prevent the two ends of the rubber conveyor belt 5 from being subjected to excessive concentration of traction by the two belt rollers 3, resulting in the breakage of the rubber conveyor belt 5 or cracks on the side, thereby extending the service life of the rubber conveyor belt 5;

[0049] As the multiple clamping mechanisms continue to move, when the two guide slide shafts 114 in each clamping mechanism slide back into the inner side of the guide slide groove 11 from the inner side of the upper slide groove 12 and the lower slide groove 13 respectively, the two guide slide shafts 114 drive the reversing rod 113 to rotate back to the horizontal angle. According to the above principle, the two clamping plates 104 can be driven to separate and release the clamping of the rubber conveyor belt 5. Then, as the clamping mechanism continues to move, when the roller 117 passes the inclined push surface 9 at the other end of the guide strip 8, the return spring 115 releases the elastic force acting on one end of the first convex ring 110, thereby pushing the sliding sleeve 106 to move in the opposite direction along the inner side of the fixed sleeve 105, thereby driving the two clamping plates 104 away from the side of the rubber conveyor belt 5, eliminating the overlapping part of the clamping plates 104 and the rubber conveyor belt 5, so that each clamping mechanism can continuously move in a cycle with the synchronous belt 7;

[0050] Since two movable guide rods 118 are slidably inserted inside the two clamping plates 104, one end of the two movable guide rods 118 at the same height is fixed with a buffer clamping plate 119, and the outer side of each movable guide rod 118 is sleeved with a buffer spring 120, when the two buffer clamping plates 119 are gradually clamped on the inner and outer sides of the rubber conveyor belt 5 under the action of the two clamping plates 104, each buffer spring 120 is slowly compressed, so that the clamping force is gradually applied to the inner and outer sides of the rubber conveyor belt 5, effectively avoiding the deformation of the side of the rubber conveyor belt 5 caused by the excessive clamping force applied instantly;

[0051] The rotating cylinder 204 of multiple buffer support mechanisms is in contact with the inner upper surface of the rubber conveyor belt 5, supporting the upper surface of the rubber conveyor belt 5. The rotating cylinder 204 is rotatably connected to the outer side of the fixed rod 202, which can reduce the friction between the rotating cylinder 204 and the rubber conveyor belt 5 and reduce the resistance of the rubber conveyor belt 5 when rotating. When the material hits the upper side of the rubber conveyor belt 5, the impact force acts on the rotating cylinder 204 in the buffer support mechanism at the corresponding position through the rubber conveyor belt 5, and then is transmitted to each spring piece 205 through the fixed rod 202. Each spring piece 205 can buffer the impact force to a certain extent, thereby protecting the rubber conveyor belt 5 and preventing the rubber conveyor belt 5 from being broken due to excessive impact force.

[0052] The above description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
