Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

Referring now to fig. 1 to 2, a belt tensioner according to an embodiment of the present invention is described, including a frame 100, a drum 300, a tension connection block 200, and a tension member 400. The rack 100 is provided with a first chute 110, and two ends of the first chute 110 are provided with a connecting plate 120 which is vertically upward; the sliding blocks 310 are arranged at both ends of the drum 300, and the sliding blocks 310 can move in the first sliding chute 110; two ends of the tensioning connecting block 200 are connected with the connecting plate 120 through bolts and limit the sliding block 310 to move up and down with the first sliding chute 110; the tension member 400 is disposed on the connection plate 120 and pulls the slider 310 such that the drum 300 tensions the belt.

For example, referring to fig. 1, the frame 100 is fixed to the end of the belt conveyor, and since the drum 300 is normally pulled leftward to tension the belt, the first chute 110 is disposed in a direction parallel to the moving direction of the belt. The sliding blocks 310 are installed at both ends of the drum 300, and the sliding blocks 310 are driven by the tension element 400 to slide leftward in the sliding grooves, so that the drum 300 slides leftward, and a belt is tensioned. The first sliding groove 110 performs sliding guiding, and the tension connection block 200 presses the sliding block 310 downward to keep the sliding block 310 attached to the first sliding groove 110, thereby ensuring the guiding effect of the first sliding groove 110, and preventing the roller 300 from being separated from the sliding groove upward, so that the sliding block 310 is sufficiently fixed except for the sliding direction, and can only perform adjustment movement by the tension element 400. The slider 310 can be fixed without adjusting the tension element 400, ensuring proper operation of the belt. The tensioning connecting block 200 is connected with two ends of the connecting plate 120 through bolts, so that the assembly and disassembly are convenient.

According to some embodiments of the present invention, the tension element 400 is an adjusting screw, and the tension element 400 is disposed on the connecting plate 120 and can drive the sliding block 310 to move in a direction away from the frame 100. For example, referring to fig. 1, the tension member 400 is provided on the left connection plate 120 and is connected to the slider 310 through the connection plate 120 by a screw hole. During the rotation process of the adjusting screw rod, the screw thread moves back and forth, so that the sliding block 310 is driven to move to realize tensioning. It can be understood that the adjusting screw can also be disposed on the connecting plate 120 on the right side to achieve the same technical effect, but the adjusting screw at the right end is inconvenient for the worker to adjust.

According to some embodiments of the present invention, the end of the two tension connection blocks 200 away from the drum 300 is provided with an end connection plate 210. For example, referring to fig. 2, the drum 300 pulls the belt to the left to tension the belt. And the drum 300 itself is subjected to a tensile force of both ends to the left and a tensile force of the belt to the right in the middle. Because the stress on the roller 300 is unevenly distributed, the tensioning devices on the two sides are outwards expanded to form a splayed shape, so that the roller 300 is easy to bend and deform, and is easy to break and damage in the use process. For this purpose, the end of the tensioner remote from the drum 300 is connected by the tail web 210, avoiding the tensioner from flaring out. Thereby preventing the bending breakage of the drum 300.

According to some embodiments of the present invention, a sweeper 130 for the inner side of the race belt is provided in the frame 100. For example, referring to fig. 1 and 2, the belt and the drum 300 are closely fitted, and the pressure between the drum 300 and the belt is large in order to tighten the belt. If the inner surface of the belt has chips or sundries, the belt and the roller 300 can clamp the chips when passing through the roller 300, so that the belt or the roller 300 is easily damaged, and particularly, when the chips are sharp, the belt can be cut, and the use is influenced. To avoid debris entering the drum 300 with the belt, the belt is typically cleaned before entering the drum 300. As shown, the lower belt moves to the left into the drum 300 and the sweeper 130 sweeps against the belt surface.

Specifically, the sweeper 130 includes a fixing frame 131, a connecting rod 132 and a cleaning brush 133, the fixing frame 131 is disposed on the frame 100, one end of the connecting rod 132 is hinged to the fixing frame 131, the other end of the connecting rod 132 is hinged to the cleaning brush 133, and the cleaning brush 133 is abutted against the inner side of the belt for sweeping. For example, referring to fig. 1, in order to ensure that the sweeper 130 can constantly maintain the contact with the belt due to the possibility of up-and-down shaking of the belt during movement, the cleaning brush 133 is movably connected to the fixing bracket 131 on the frame 100 through the connecting rod 132, and the cleaning brush 133 can freely swing up and down and maintain the contact with the belt through its own gravity.

According to some embodiments of the present invention, the drum 300 includes a rotating shaft 320 and a cylinder 330, a supporting frame 340 is disposed between the rotating shaft 320 and the cylinder 330, and the sliding blocks 310 are disposed at both ends of the rotating shaft 320. For example, referring to fig. 1, in order to reduce the weight of the drum 300, reduce the load when the belt rotates, and maintain the large diameter of the drum 300, the drum 300 is generally designed to be hollow, and both ends are connected by the rotating shaft 320, and the outer cylinder 330 and the inner rotating shaft 320 are connected and supported by the supporting frame 340, so that the structural strength is maintained, and the weight is effectively reduced.

According to some embodiments of the present invention, the supporting frame 340 is provided with a reinforcing rib 350, for example, referring to fig. 2, since the drum 300 is easily stressed and bent during the movement process, in order to increase the strength of the supporting frame 340, the reinforcing rib 350 is generally provided on the supporting frame 340 near both ends of the drum 300, so as to improve the mechanical properties of the supporting frame 340, and the overall structure of the drum 300 is more stable.

The utility model discloses a theory of operation does: when the belt tensioning device is installed, the roller 300 is firstly placed on the first sliding groove 110 after escaping into the belt, and is connected with the connecting plate 120 through the tensioning connecting block 200 to form a complete sliding groove, after the belt tensioning device is installed, the tensioning element 400 is connected with the sliding block 310, and the sliding block 310 is pulled backwards through the tensioning element 400, so that tensioning is realized. The mode of tensioning after installation is adopted for use, and the mode of tensioning before installation does not need to be performed like the traditional tensioning device, so that the installation is more convenient.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
