Description

Technical Field

[0001] The invention relates to a European-style conveyor with an empty return hook, belonging to the field of slaughtering equipment. Background Art

[0002] Most of the empty hook conveyors use PE plates as chain tracks. The chain uses sleeve roller chains. Special chain plates are made on the chain links of the set length. The special chain plates are equipped with a plate rack. The plate rack is equipped with a plate. Due to structural restrictions, the plate is installed on the side of the chain. When the chain moves, it will produce a certain lateral force, which increases the wear of the chain and the track. Because the sleeve roller chain is used, the conveyor can only move in a straight line. When encountering a situation where horizontal turning is required, it can only be made in sections. The downward track is used at the turning connection of the two conveyors. The hook is prone to drop here, and a guard rail needs to be installed. Summary of the invention

[0003] According to the background problem, the problem to be solved by the present invention is:

[0004] The return hook conveyor can only move in a straight line, and the turning requires two conveyors to be made in sections; a sliding track is used at the turning connection of the two conveyors, and the hook is prone to falling off here, so a guard rail needs to be installed.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A European-style conveyor with an empty hook includes a driving end, a driven end, a corner system and a double-hinged chain; the driving end includes a reducer, a driving sprocket, a driving end frame and a driving end fixed frame, the reducer is connected to the driving sprocket through a transmission shaft, the reducer is fixed on the driving end frame, and the upper part of the driving end frame is connected to the fixed frame; the driven end includes a tensioning mechanism, a double-linked airbag cylinder, a square seat bearing, a driven sprocket, a driven end fixed frame and a driven end frame, the driven end sprocket center is connected to the square seat bearing, the square seat bearing is connected to the tensioning mechanism, and the tensioning mechanism The structure and the double air bag cylinder are fixed on the driven end frame, the tensioning mechanism is connected to the double air bag cylinder, and the driven end frame is connected to the driven end fixed frame; the corner system includes a hanging frame, an angle sprocket track, an angle sprocket, a pulley hook track and a hanger, a sprocket track is provided under the hanging frame, the angle sprocket is provided on the inner side of the sprocket track, the sprocket track is connected to the pulley hook track through the hanger, and the pulley hook track is provided under the sprocket track; the double-hinged chain connects the driving sprocket, the angle sprocket and the driven sprocket, and the double-hinged chain is connected to a paddle plate through a paddle plate fixed frame below.

[0007] Preferably, the double hinge strips are unequally spaced double hinge strips, and the double hinge strips can be bent up and down while being bent left and right.

[0008] Preferably, the paddle plate fixing frame is connected to a protective baffle, and the protective baffle is located behind the paddle plate.

[0009] Preferably, the corner system is divided into an inner hanger corner system and an outer hanger corner system, wherein the hanger is on the inner side of the pulley hook track in the inner hanger corner system and the hanger is on the outer side of the pulley hook track in the outer hanger corner system. The inner hanger corner system corresponds to the case where the pulley hook body passes through the outer side of the pulley hook track, and the outer hanger corner system corresponds to the case where the pulley hook body passes through the inner side of the pulley hook track.

[0010] Preferably, the paddle is a polyurethane plate, and the paddle is T-shaped or rectangular; the polyurethane material has good toughness and can be restored to its original state after multiple bendings.

[0011] The European-style empty-hook conveyor adopts a vertical double-layer rotary track and is matched with a double-hinged chain, so that one chain can simultaneously complete two actions: turning left and right and climbing up and down. The reduction in the number of chains required corresponds to the reduction in the number of power sources, that is, the number of conveyors required, which saves costs. One European-style empty-hook conveyor can meet complex site requirements; the driven end of the European-style empty-hook conveyor is provided with a tensioning device connected to a double-linked air bag cylinder, and the tension of the double-linked air bag cylinder is adjusted by the contraction and expansion of the double-linked air bag cylinder, reducing the difficulty of adjustment; a paddle plate fixing frame is installed at the bottom of the double-hinged chain, and a T-shaped or rectangular paddle plate is installed on the paddle plate fixing frame, according to the use of the pulley hook and the use of Different occasions require different paddles to be installed. The paddles are made of high-elastic polyurethane plates. The polyurethane paddles have good toughness, high elasticity, and a certain hardness. When pushing the pulley hooks, they can ensure that multiple pulley hooks are pushed at the same time. When the pulley hooks on the line are full, the pulley hooks can no longer be moved forward. At this time, there is no need to stop the empty hook conveyor line. The resistance encountered by the paddle plate when moving the pulley hook group is too large, and the paddle plate bends and slides over the upper end of the pulley hook. When a gap appears at the front end of the conveyor, the resistance is reduced, and the paddle plate no longer bends after being stressed, and the pulley hook can be transported forward. The protective baffle prevents the paddle plate from bending too much and breaking, thereby reducing the maintenance frequency and cost of the empty hook European conveyor.

[0012] The beneficial effects of the present invention are:

[0013] The shifting plate and the track can be placed directly below the hanging beam, with the center of gravity pointing vertically downward, so that the conveyor will not be tilted or stressed.

[0014] The empty hook conveyor can climb up and down and turn left and right according to the layout of the factory, and there is no need to connect multiple conveyors for transportation within the effective length.

[0015] The installation is simple. The upper end of the track is directly hung on the bottom of the main steel beam and fixed with a bolt pressure plate. The power end and the driven end are fixed with double brackets. Vertical installation saves space.

[0016] The track and corner wheels are double-layered with compact structure, saving materials and increasing frame strength.

[0017] It runs smoothly and can realize 180° and 90° reversing transportation. The hook is not likely to fall off at the reversing point.

[0018] The airbag cylinder tensioning device is adopted, which ensures moderate chain tension and relaxation, low noise and prolongs the service life of the chain. BRIEF DESCRIPTION OF THE DRAWINGS
