Description

TECHNICAL FIELD

[0001] The utility model belongs to the conveyor technical field, concretely relates to a conveying belt deviation rectifying mechanism and conveyor. BACKGROUND

[0002] The conveyor is composed of a frame, a plurality of transmission rollers, at least one power roller and a conveying belt. The conveying belt passes through the transmission rollers and the power roller, and rotates between the plurality of transmission rollers. Therefore, when the material is placed on the conveying belt, the conveying belt can move the material. Since the axial center lines of the plurality of transmission rollers on the conveyor are difficult to be completely parallel, the transmission rollers can change the moving direction of the conveying belt, resulting in deviation of the conveying belt during movement. Thus, the conveying belt is easy to touch the frame, causing wear of the conveying belt and affecting the service life of the conveying belt. In addition, the conveying belt is usually annular during use. Since the lengths of the conveying belts are difficult to be completely the same, the moving distances of the two sides of the conveying belt are different, and the conveying belt deviates during movement, also causing wear of the conveying belt.

[0003] In the prior art, patent number 202123212593 2 discloses a conveying belt deviation rectifying device. The conveying belt deviation rectifying device includes a frame and a deviation rectifying assembly. The deviation rectifying assembly includes a deviation rectifying roller, a push-pull element and a detection unit. The deviation rectifying roller is movably arranged on the frame. The push-pull element is arranged on the frame in a manner capable of pushing the deviation rectifying roller to swing horizontally. The push-pull element drives the deviation rectifying roller to swing horizontally according to the deviation amount of the conveying belt, so as to correct the direction of the conveying belt. However, the single adjustment of the swing of one end of the deviation rectifying roller not only causes the connection between the deviation rectifying roller and the frame to be not firm, but also easily causes the device to be damaged during long-term use.

[0030] Now a conveying belt deviation correction mechanism and a conveyor provided by the present application will be described.

[0031] In a first aspect, see Figure 1 and Figure 2 A conveying belt deviation correction mechanism comprises a support, a connecting frame, a swing frame, two drive assemblies and a deviation correction roller. The connecting frame is provided with a hollow chamber, the connecting frame is arranged on the support, and the two ends of the connecting frame are connected with the support respectively; the swing frame is arranged in the hollow chamber, and the swing frame is rotationally connected with the connecting frame through a pin shaft; the two drive assemblies are arranged in the hollow chamber, and the two drive assemblies are symmetrically arranged at the two ends of the swing frame along the length direction of the swing frame, and the power output end of the drive assembly is rotationally connected with the swing frame; the deviation correction roller is rotationally connected with the swing frame, and the central axis of the deviation correction roller is arranged in parallel with the length direction of the connecting frame.

[0032] Compared with the prior art, the conveying belt deviation correction mechanism provided in the embodiment places the conveying belt on the deviation correction roller. Since the two drive assemblies are rotationally connected with the two ends of the swing frame, and the swing frame is rotationally connected with the connecting frame through a pin shaft, when the conveying belt deviates, the drive assemblies are started, and the two drive assemblies are adjusted in contraction and thrust according to the deviation of the conveying belt, so as to adjust the swing amplitude of the deviation correction roller, so as to realize automatic deviation correction adjustment of the conveying belt. Compared with adjusting the swing of one end of the deviation correction roller to adjust the conveying belt, the swing frame and the two drive assemblies are arranged, the rotation of the swing frame is controlled by the drive assemblies, and then the swing of the deviation correction roller is controlled, so as to realize the purpose of correcting the conveying belt, and solve the technical problems that the connection between the deviation correction roller and the frame body is not firm, and the equipment is easily damaged during long-term use of the device.

[0033] See Figure 3 , in combination with the first aspect, in some embodiments, the support comprises two frame bodies, the two frame bodies are arranged in parallel, and the frame body comprises a bottom plate, two vertical plates and a connecting shaft. The bottom plate is horizontally arranged; the two vertical plates are vertically arranged on the bottom plate, and the two vertical plates are symmetrically arranged on both sides of the length of the bottom plate; and the connecting shaft is arranged in parallel above the bottom plate, and the two ends of the connecting shaft are rotationally connected with the two vertical plates respectively.

[0034] See Figure 4 and Figure 5 The connecting frame comprises two sliding boxes and two panels. The two sliding boxes are arranged in one-to-one correspondence with the two frame bodies, and the sliding boxes are slidingly sleeved on the connecting shaft; the two panels are horizontally and spacedly arranged along the height direction of the support, and the two ends of the two panels are fixedly connected with the two sliding boxes respectively.

[0035] Among them, the two sliding boxes and the two panels surround the hollow chamber for accommodating the swing frame.

[0036] Since the sliding box sliding sleeve is arranged on the connecting shaft, the sliding box is slidingly connected with the frame body, when it is needed to adjust the overall tension of the conveying belt, only the position of the connecting frame on the frame body needs to be adjusted, so that the overall tension of the conveying belt can be adjusted, and since the sliding box and the frame body are slidingly connected, the operation of carrying the overall deviation rectifying mechanism is omitted during movement, and the operation is more convenient.

[0037] Further, the sliding box is filled with lubricating grease, so as to reduce the friction when the sliding box slides on the connecting shaft.

[0038] Referring to Figure 2 On the basis of the above embodiment, the driving assembly comprises a fixed frame and a pushing piece. The fixed frame is arranged on the side of the hollow chamber away from the deviation rectifying roller, and the fixed frame is fixedly connected with the two panels respectively; one end of the pushing piece is rotatably connected with the fixed frame, and the other end is rotatably connected with the swing frame.

[0039] When one pushing piece pushes, since the swing frame is rotatably connected with the connecting frame through the pin shaft, the other side of the swing frame is subjected to extrusion force, so that the pushing piece on the other side is started to retract, so as to drive the swing frame to normally rotate.

[0040] Referring to Figure 6 Further, the swing frame comprises a rotating part and two deviation rectifying parts. The rotating part is arranged in the hollow chamber, the rotating part is rotatably connected with the two panels, and the two deviation rectifying parts are symmetrically arranged at the two ends of the rotating part respectively. The two deviation rectifying parts are correspondingly arranged with the two pushing pieces, the tail end of the deviation rectifying part is rotatably connected with the pushing piece, and the top end of the deviation rectifying part is rotatably connected with the deviation rectifying roller. The pushing piece is started, and since the tail end of the deviation rectifying part is rotatably connected with the power output end of the pushing piece, when the deviation rectifying part is subjected to the pushing or retraction of the pushing piece, the deviation rectifying part rotates with the pushing piece.

[0041] The swing frame is rotatably connected with the connecting frame through the pin shaft, so that the swing frame can better rotate when subjected to the pushing or retraction of the pushing piece, so as to drive the horizontal swing of the deviation rectifying roller.

[0042] In some embodiments, an adjusting friction plate is arranged between the top surface of the swing frame and the bottom of the panel, a plurality of grooves are arranged on the adjusting friction plate, and the grooves are used to accommodate lubricating oil.

[0043] The lubricating oil in the grooves can reduce the friction between the adjusting friction plate and the panel, so that the swing frame can better rotate and swing.

[0044] Specifically, an adjusting friction plate is also arranged between the lower surface of the swing frame and the bottom panel.

[0045] Further, a pressurized oil cup is further arranged on the panel, the pressurized oil cup is in communication with the grooves, and the lubricating oil is pressurized through the pressurized oil cup.

[0046] Further, a reinforcing plate is arranged between the two panels, the reinforcing plate is arranged vertically between the two panels, and the reinforcing plate is arranged on the side of the panel close to the deviation correcting roller.

[0047] The reinforcing plate can improve the connection strength between the two panels.

[0048] Specifically, the reinforcing plate has a V-shaped structure, which can be adapted to the rotation of the swing frame, avoiding collision between the swing frame and the reinforcing plate during the rotation of the swing frame, thereby avoiding damage to the equipment.

[0049] Specifically, the pushing piece is an electric push rod or an air cylinder, and the power output end of the pushing piece is connected to the deviation correcting part in a pin joint, a bolt joint, a clamping joint or an abutting joint.

[0050] As another embodiment, a hydraulic cylinder can be used for adjusting a heavy conveyor belt.

[0051] The hydraulic cylinder mainly converts hydraulic energy into mechanical energy, and is mainly used as a linear reciprocating hydraulic actuator. The structure of the entire device is simple and reliable, and when used, it can realize reciprocating motion without the need for a speed reducer and without transmission gaps, and the operation is very stable. Therefore, it is widely used in various mechanical hydraulic systems.

[0052] The output force of the hydraulic cylinder is proportional to the effective area of the piston and the pressure difference between the two sides. The hydraulic cylinder basically consists of a cylinder barrel and a cylinder cover, a piston and a piston rod, a sealing device, a buffer device, and an exhaust device.

[0053] The structure of the hydraulic cylinder is various, and according to the movement mode, it can be effectively divided into linear reciprocating type and rotary swing type. According to the hydraulic pressure acting condition, it can be divided into single-acting type and double-acting type. According to the structure, it can be divided into piston type, plunger type and swing type.

[0054] In a single-acting hydraulic cylinder, the pressure oil is supplied to only one cavity of the hydraulic cylinder, and the cylinder moves in one direction by hydraulic pressure. The reverse direction movement is realized by external force such as spring force, self-weight or external load. In a double-acting hydraulic cylinder, the piston moves in two directions by the action of hydraulic pressure through the alternating oil supply of two cavities.

[0055] The piston type hydraulic cylinder can be divided into single-rod type and double-rod type structures, and its fixing mode can be cylinder body fixing and piston rod fixing. According to the hydraulic pressure acting condition, it can be single-acting type and double-acting type. In a single-acting hydraulic cylinder, the pressure oil is supplied to only one cavity of the hydraulic cylinder, and the cylinder moves in one direction by hydraulic pressure. The reverse direction movement is realized by external force such as spring force, self-weight or external load. In a double-acting hydraulic cylinder, the piston moves in two directions by the action of hydraulic pressure through the alternating oil supply of two cavities.

[0056] Electric push rod is also called linear drive, mainly by motor push rod and control device and other mechanisms composed of a new type of linear actuator, can be considered as a rotary motor in the structure of a kind of extension.

[0057] Electric push rod is a kind of electric power drive device which converts the rotary motion of motor into the linear reciprocating motion of push rod. It can be used as an execution machine in various simple or complex process to realize remote control, centralized control or automatic control.

[0058] Electric push rod has the characteristics of novel and exquisite design, small size, high precision, complete synchronization, good self-locking performance, hygiene, motor direct drive, no need for pipeline gas source, oil circuit and other characteristics. It has been widely used in production line, automobile, air window opening, military, stage, textile, sewage treatment and other industries.

[0059] Based on the same inventive concept, the embodiments of the present application also provide a conveyor, which comprises the conveyor belt deviation rectifying mechanism in the above-mentioned scheme.

[0060] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
