[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the solution will be further described in detail below in conjunction with specific embodiments.

[0030] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a conveying flat belt joint grinding device, which includes a fixed base plate 11, a belt limiting assembly for pressing the belt onto the fixed base plate 11, a belt grinding mechanism for grinding the joint of the belt, a driving member for driving the belt grinding mechanism to operate, and a clamping mechanism for clamping the fixed base plate 11 on a work surface, the belt limiting assembly is arranged on one side of the fixed base plate 11, and the belt grinding mechanism is arranged on the other side of the fixed base plate; the belt limiting assembly and the belt grinding mechanism are arranged opposite to each other.

[0031] The conveyor flat belt joint grinding device provided in the embodiment of the present invention, when in use, clamps the fixed base plate 11 on the work surface through the clamping mechanism, and then uses the belt limiting assembly to press the belt, and then drives the belt grinding mechanism to operate through the driving member to grind the belt joint, thereby better avoiding the use of a file for manual grinding, and making the grinding of the belt joint more time-saving and labor-saving, and effectively improving the grinding efficiency.

[0032] Furthermore, the belt grinding mechanism includes a first support plate 37, a second support plate, a roller 34, and a sanding belt 33. The first support plate 37 and the second support plate are relatively arranged on the other side of the fixed bottom plate; the sanding belt 33 is sleeved outside the roller; the roller is horizontally arranged between the first support plate and the second support plate, and a rotating shaft 341 is arranged at the middle position of both ends of the roller, and the first support plate and the second support plate are respectively provided with through holes that cooperate with the rotating shaft for rotation; the driving member is used to drive the rotating shaft at the left end of the roller to rotate; a grinding block 35 is arranged below the sanding belt, and the joint of the belt is clamped in the gap between the grinding block and the sanding belt. With this scheme, the driving member drives the rotating shaft to rotate, and the roller and the sanding belt rotate with the rotation of the rotating shaft. The rotating sanding belt is used to grind the joint of the belt, so that the polished belt joint has a better quality, which is easy to meet the technical requirements of the cold bonding joint method, improve the bonding quality, and ensure the reliable operation of the belt conveyor.

[0033] In order to enable the rotating shaft 341 to rotate more smoothly, a bearing 32 is disposed in the through hole.

[0034] Specifically, the second support plate includes an upper plate 39 and a lower plate 31, and the upper plate is detachably connected to the lower plate; the through hole on the second support plate is arranged on the upper plate, so as to facilitate the installation of the roller and the grinding block during assembly. Preferably, the upper plate is an inverted L-shaped structure, and the lower plate is an L-shaped structure adapted to the upper plate, and the upper plate and the lower plate can be connected by screws.

[0035] In order to achieve a better grinding effect, the grinding block 35 is an arc block, and the arc surface of the grinding block is opposite to the sanding belt 33. Preferably, the arc block is a quarter arc block. Preferably, the roller is a rubber roller to facilitate the installation of the sanding belt and increase the friction between the roller and the sanding belt to prevent the sanding belt from slipping relative to the roller.

[0036] Furthermore, the two ends of the grinding block 35 are rotatably connected to the first support plate and the second support plate through a rotating shaft 37, and the axis of the rotating shaft 37 is located on the side of the center of gravity of the grinding block away from the belt limiting assembly; the lower side edge 351 of the grinding block close to the belt limiting assembly is in contact with the fixed base plate; a gap is provided between the lower side edge 352 of the grinding block away from the belt limiting assembly and the fixed base plate for the grinding block to rotate around the rotating shaft at a certain angle; the upper part of the grinding block 35 away from the belt limiting assembly is connected to the fixed base plate through an elastic member 36. With this solution, the axis of the rotating shaft 37 is located on the side of the center of gravity of the grinding block away from the belt limiting assembly, that is, the rotating shaft is eccentrically arranged on the grinding block, and the grinding block is rotatably connected to the first support plate and the second support plate, so that when the outermost end of the belt joint is polished and thinned, that is, when the grinding is completed, the eccentrically arranged grinding block is driven by the high-speed rotating sanding belt to rotate a certain angle in the direction opposite to the rotation direction of the sanding belt, and then continues to grind the belt joint, and repeats this cycle until the joint is completely polished, thereby making the grinding of the belt joint more convenient, more time-saving and labor-saving; at the same time, using the sanding belt in conjunction with the follow-up grinding block to grind the belt joint can ensure that the belt joint is evenly polished, and the belt joint after grinding is relatively smooth, thereby ensuring the splicing quality of the belt. It can be understood that if Figure 2 As shown, the number of elastic parts can be two, and the two ends of the upper part of the grinding block 35 away from the belt limiting assembly are respectively connected to the fixed base plate through elastic parts 36; the elastic parts can preferably be springs; the rotation range of the grinding block can be within forty-five degrees; the rotating shaft can pass through the grinding block, and the two ends of the rotating shaft are respectively rotatably connected to the first support plate and the second support plate, and the grinding block 35 can be fixed on the rotating shaft by fixing screws 38.

[0037] Preferably, the driving member is connected to the rotating shaft at the left end of the drum through an elastic coupling 41, so that the elastic coupling 41 can better avoid a small amount of misalignment between the driving head of the driving member and the rotating shaft 341 caused by assembly error, so that the operation of the drum 34 is relatively stable. It can be understood that the structure of the elastic coupling 41 is the same as that of the elastic coupling in the prior art, and will not be repeated here.

[0038] Furthermore, the clamping mechanism includes a clamping column 55, a clamping handle 53, and a clamping bolt 54 arranged on the top surface of the fixed base plate. The clamping handle is a U-shaped structure, one end of the clamping handle is connected to the clamping column 55, and the other end of the clamping handle is provided with a threaded hole for matching with the threaded section of the clamping bolt; the clamping bolt is located below the fixed base plate, and the bolt head of the clamping bolt 54 is located below the threaded hole, so that after the fixed base plate is placed on the work surface, it is only necessary to rotate the clamping bolt so that the upper end of the clamping bolt is pressed against the bottom surface of the work surface, and the fixed base plate can be clamped on the work surface. It can be understood that the clamping column can be arranged opposite to the first support plate.

[0039] Preferably, the driving member is an electric drill, and the upper end of the clamping column is provided with a clamping assembly for clamping the drill bit tube of the electric drill, and the drill bit extending from the drill bit tube is coaxially connected to the rotating shaft at the left end of the drum; the clamping assembly includes a first clamping ring 56, a second clamping ring 51, a clamping stud 57, and a clamping nut 58, the outer wall surface of the first clamping ring is connected to the upper end of the clamping column, and one end of the first clamping ring 56 is hingedly connected to one end of the second clamping ring; the other end of the first clamping ring and the other end of the second clamping ring are provided with corresponding connecting holes, and the threaded section of the clamping stud passes through the connecting hole and cooperates with the clamping nut. With this scheme, the drill bit tube is clamped by the first clamping ring and the second clamping ring, so as to better avoid large shaking of the drill bit tube during grinding, thereby ensuring the grinding quality. It can be understood that two upwardly inclined trigger plates 52 can be relatively arranged on the clamping nut to facilitate the rotation of the clamping nut; after the drill bit tube of the electric drill is placed in the first clamping ring, the second clamping ring is buckled, and then the clamping nut is tightened to press the second clamping ring onto the first clamping ring, thereby achieving the clamping of the drill bit tube. After clamping, the drill bit tube needs to be coaxial with the rotating shaft to ensure better grinding quality; the drill bit of the electric drill extends out of the drill bit tube and is coaxial with the drill bit tube, and the drill bit of the electric drill is the driving head of the driving member; when an elastic coupling is provided, one end of the elastic coupling 41 can be connected to an electric drill connector 61 for connecting to the drill bit of the electric drill, and the electric drill connector 61 can be connected to the elastic coupling through a locking screw 42, and the other end of the elastic coupling can be connected to the rotating shaft 341 through a locking screw 42; Figure 1 As shown, the first clamping ring and the second clamping ring are both arc-shaped rings with openings facing each other to form a ring structure; the electric drill is not shown in the figure.

[0040] Specifically, the belt limiting assembly includes two limiting studs 22, a pressure strip 23, and two limiting nuts 21. The two limiting studs are relatively arranged on one side of the fixed base plate, and the two ends of the pressure strip are respectively provided with through holes for the two limiting studs 22 to pass through; a gap is provided between the pressure strip and the fixed base plate for the belt to pass through; the end of the limiting stud 22 away from the fixed base plate passes through the through hole and then cooperates with the limiting nut 21; the two limiting nuts correspond to the two limiting studs in a one-to-one manner, so that after the belt passes through the above-mentioned gap, when the joint of the belt is located at the grinding position of the belt grinding mechanism, the limiting nut is rotated to press the pressure strip on the belt, so that the belt can be limited to prevent the belt from moving too much into the belt grinding mechanism. It can be understood that although the pressure strip presses the belt against the fixed base plate, the belt can move to a certain extent. For example, when the grinding block rotates, a small section of the belt will pass through the gap and move toward the grinding block. Two upwardly inclined lever pieces 24 can be relatively arranged on the limit nut to facilitate the rotation of the limit nut 21.

[0041] The conveyor flat belt joint grinding device provided in the embodiment of the present invention can be adjusted according to the belt width, and the belt width range that can be ground is 10 to 100 mm; it uses an electric drill as the power input of the belt grinding mechanism, and drives the sanding belt through the roller to grind the belt, which can improve the grinding efficiency and reduce labor intensity. The belt joint after grinding has better flatness, is convenient for bonding, and has good durability after bonding.

[0042] The above are only preferred embodiments of the present invention. It should be pointed out that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. Moreover, after reading the contents of the present invention, relevant technical personnel in the field may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.
