Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ventilation duct conveying, in particular to a directional guiding conveying device in the production process of a ventilation duct. BACKGROUND

[0002] Ventilation ducts are used in the ventilation and air conditioning engineering of industrial and civil buildings, and are used to convey air, flue gas and other media. Common raw materials include galvanized sheet and stainless steel sheet. The ventilation ducts need to go through multiple processing procedures from sheet material to forming, including bite machine, bending machine, common sheet flange forming machine and other equipment for processing cut sheet material, such as connecting sheet material into a duct by mechanical bite or welding process. For circular air ducts, a spiral air duct machine is often used for one-time forming processing. For rectangular air ducts, common sheet flanges or angle steel flanges and other connection methods may be used for assembly.

[0003] Most commonly used ventilation duct production equipment currently adopts an integrated processing method of five or six lines, that is, the equipment can directly process and produce from sheet material blanking, edge cutting, bending to final forming. During this period, a conveying device is needed to move the sheet material or semi-finished ventilation duct from the outlet of one equipment to the inlet of another equipment, so as to realize automatic continuous processing. Due to site reasons, part of the processing equipment cannot realize straight-line conveying, and needs to cross the line to convey the sheet material between every two processing equipment, that is, the sheet material is moved from one conveying line to another conveying line, and then the sheet material is conveyed in another direction by another conveying line.

[0004] The above cross-line operation is generally operated by an industrial robot or a reciprocating push rod is installed in the roller conveyor, so as to push the sheet material from one conveyor to another conveyor. No matter which operation, the empty reset will occur after the sheet material is placed. The empty reset time cannot transport the sheet material, but the conveyor still transports the sheet material during this period. In order to meet the return gap of the industrial robot or the push rod, the gap between two sheet materials needs to be strictly controlled, the gap between the two sheet materials is increased, and the normal transportation of the sheet material is ensured during the return process of the industrial robot or the push rod. This will reduce the conveying efficiency of the sheet material and cause the overall production efficiency of the ventilation duct to decrease. SUMMARY

[0016] As a further technical scheme of the present application, the side surface of the mounting side shelf and the side surface of the end fixed frame are integrally provided with a perforated spring scraper corresponding to the tension spring, and the two ends of the tension spring are hung and connected with the perforated spring scraper on the side surface of the mounting side shelf and the perforated spring scraper on the side surface of the end fixed frame.

[0017] As a further technical scheme of the present application, the guide limiting mechanism is further provided with an upper pushing reset mechanism movably connected below the guide limiting mechanism.

[0018] The upper pushing reset mechanism is provided with a support transverse plate, and both ends of the support transverse plate are fixedly connected with the bottom of the limiting stand column below the guide rail side plate.

[0023] (3) Beneficial effects:

[0024] A、In the present application, first, the cut plate is moved by the material conveying rollers arranged in a rectangular array, when the plate moves to the end of the conveyor rack, the driving gear and the driven gear at the end of the material conveying roller are engaged with each other, thereby driving the driving worm to rotate, and then the center sliding block is driven to move by the mutual engagement between the driving worm and the worm gear fitting groove, and then the installation side frame on both sides is moved by the center sliding block, and the workpiece shifting rod above the installation side frame pushes the plate above the material conveying roller to move horizontally, thereby pushing the plate at the end of the conveyor rack to the end of the auxiliary conveying belt, and then the plate is conveyed to the subsequent processing equipment by the auxiliary conveying belt, thereby processing the plate into a ventilation duct, and the workpiece shifting rod is driven to move horizontally by the rotating material conveying roller, which not only can convey the plate, but also can move the plate in a direction, thereby moving the plate to the specified equipment for processing.

[0025] B. In the present invention, after the workpiece shifting rod moves the plate from the top of the conveyor frame to the top of the auxiliary conveyor belt, the center slider will move to the limit position. At this time, the sliding guide column at the end of the installation side display rack will move to the end along the guide groove, and then, under the guidance of the inclined slide groove at the end of the guide groove, cooperate with the tension of the tension spring to make the sliding guide column quickly return along the slide groove at the lower inner side of the guide groove. When the sliding guide column moves into the slide groove in the lower half of the guide groove, the worm gear matching groove above the center slider will separate from the driving worm. At the same time, the workpiece shifting rod above the installation side display rack will also move downward, so that the top end of the workpiece shifting rod is lower than the upper surface of the material conveying roller, thereby realizing the rapid reset of the center slider, and the center slider will not affect the plate transported above the material conveying roller when it is reset, thereby improving the efficiency during transportation.

[0026] When the center slider is fully pulled to the end of the guide groove by the tension spring, there will be a sliding groove inclined upward at the end of the guide groove. At this time, the elastic force generated by the compression spring will push the center slider upward, so that the center slider moves back to the sliding groove of the guide groove at the upper part along the end of the guide groove, and the worm gear matching groove above the center slider is re-engaged with the driving worm, and the driving worm drives the center slider to move again, and the next plate is moved from the top of the conveyor frame to the top of the auxiliary conveyor belt, forming a cycle, and the entire reset action of the material guide rack does not affect the conveying of the plate by the material conveying roller, thereby improving the transportation efficiency of the plate.

[0027] D. In the present invention, when the inclined guide plate moves up and down below the guide rail side plate, the limit baffles at both ends of the inclined guide plate will slide and cooperate with the limit columns at the bottom of the guide rail side plate, so that the inclined guide plate can be vertically lifted and lowered below the guide rail side plate, preventing the inclined guide plate from offsetting when pushing the center slider to move, and the spring positioning protrusion integrally provided on the supporting cross plate and the spring positioning groove provided at the bottom of the inclined guide plate cooperate with each other, thereby limiting the two ends of the compression spring, ensuring that the elastic force of the compression spring can push the center slider upward to reset.
