Abstract

The utility model discloses a belt conveyor. The belt conveyor comprises a plurality of supporting legs and a bed body plate, wherein end portion drive pulleys are arranged at the left end portion and the right end portion of the bed body plate, a belt is arranged between the left end portion drive pulley of the bed body plate and the right end portion drive pulley of the bed body plate, a middle drive pulley is arranged in the middle of the belt, and the middle drive pulley and the end portion pulleys arranged at two end portions are all connected with a servo motor through a transmission mechanism. The belt conveyor is reasonable in structure and appropriate for different requirements of clients due to the fact that a single drive, or dual drives or three drives can be applied to driving belt conveyors to operate according to different lengths, different speeds and different load of the conveyor belts. The servo motor is applied to driving the belt conveyor, and therefore the belt conveyor has the advantages of being low in energy consumption, stable in output torque, and high in efficiency. The positions of electric rollers are determined, and therefore the belt conveyor is beneficial to standardizing, large-scale and mass production.

Description

A kind of belt feeder

Technical field

The utility model relates to the feedway in a kind of Express Logistics industry, is specifically related to a kind of belt feeder.

Background technology

The belt feeder of prior art has following several problem.The first, the belt feeder of prior art only has a head roll, power limited due to motor, in use the transmission length of growing apparatus according to specific needs, if adopt in advance the larger motor of power, can cause huge waste to electric energy before transformation.The second, the belt feeder of prior art adopts Induction Motor-Driven, and its power transfer efficiency is low, and energy consumption is large, and change speed need to increase converter plant, and drive part need to have special driver framework simultaneously, can increase cost.Three, the belt feeder of prior art is completed belt tension, is adjusted sideslip by many cylinders, and cost is higher, and the manufacturing cycle is longer.Four, be bolted between two adjacent lathe bed plates, accuracy of positioning is poor, brings difficulty for the belt adjustment in later stage.Five, the under-chassis of the belt feeder of prior art is all by upper junction plate, lower connecting plate, C type bending part three welding fabrication, in manufacturing process, first to process this three parts, reprocess out under-chassis, consuming time large, cost of labor is high, and stock utilization is lower, and the error in blanking simultaneously, Forging Process and the distortion of the generation in welding process bring hidden danger also can for later installing and using.

Summary of the invention

The deficiency that the utility model exists in order to overcome prior art provides more reasonably belt feeder of a kind of structure.

The utility model is achieved through the following technical solutions: a kind of belt feeder, comprise a plurality of supporting legs and the lathe bed plate that is arranged on these supporting legs, the right part of the left part of described lathe bed plate, described lathe bed plate is provided with the end head roll, be provided with belt between the end head roll of the end head roll of the left end of lathe bed plate and the right-hand member of lathe bed plate, head roll in the middle of the stage casing of this belt is provided with, middle head roll and two end head rolls all connect servomotor by transmission device.

The beneficial effects of the utility model are: the first, the utility model is provided with three head rolls, can be different according to length, speed, the load of belt feeder in practical work process, employing is singly driven, two driving or three drives and drives the belt feeders running, can be fit to client's different demands.The second, the utility model adopts driven by servomotor, and it has advantages of, and energy consumption is low, output torque stable, efficient is high, and the fixed of motorized pulleys position also is convenient to device normalisation, scale, mass production simultaneously.Three, adopt dovetail furrow to coordinate the location with locating piece between two adjacent lathe bed plates of the present utility model, accuracy rate is high, and adjustment brings convenience to belt, shortens belt and adjusts the time.Four, the lower bending edges of lathe bed plate is provided with positioning guiding structure, prevents belt deviation, can reduce the quantity of cylinder simultaneously.Five, under-chassis adopts laser cutting technique and the processing of numerical control bending technology, the accuracy of the position in oad and hole is effectively guaranteed, simultaneously need the position of bending to accomplish fluently mark line at under-chassis, bring for the bending operation convenient, the welding job amount of under-chassis is less simultaneously, only need spot welding after bending and molding, welding deformation amount is less, on under-chassis, control button and electronic devices and components can be installed, convenient practicality, under-chassis can also be used in conjunction with optional features such as pin cup, castors, need not to increase subsidiary part, and under-chassis can be realized standardized designs, manufacturing.

In the drawings: 1-end head roll; 2-lathe bed plate; Head roll in the middle of 3-; The 4-supporting leg.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in detail.

As Figure 1-Figure 4, a kind of belt feeder, comprise a plurality of supporting legs 4 and the lathe bed plate 2 that is arranged on these supporting legs 4, the right part of the left part of lathe bed plate 2, lathe bed plate 2 is provided with end head roll 1, be provided with belt between the end head roll 1 of the end head roll 1 of the left end of lathe bed plate 2 and the right-hand member of lathe bed plate 2, head roll 3 in the middle of the stage casing of this belt is provided with, middle head roll 3 and two end head rolls 1 all connect servomotor by transmission device.

In practical work process, according to the difference of length, speed and the load of belt feeder, adopt singly drive, two driving or three drives and drives the belt feeders running, can be fit to client's different demands.

In addition, adopt dovetail furrow to coordinate the location with locating piece between two adjacent lathe bed plates 2 of the present utility model, accuracy rate is high, and adjustment brings convenience to belt, shortens belt and adjusts the time.The lower bending edges of lathe bed plate 2 is provided with positioning guiding structure, prevents belt deviation, can reduce the quantity of cylinder simultaneously.supporting leg 4 adopts laser cutting technique and the processing of numerical control bending technology, the accuracy of the position in oad and hole is effectively guaranteed, simultaneously need the position of bending to accomplish fluently mark line at supporting leg 4, bring for the bending operation convenient, the welding job amount of supporting leg 4 is less simultaneously, only need spot welding after bending and molding, welding deformation amount is less, on supporting leg 4, control button and electronic devices and components can be installed, convenient practicality, supporting leg 4 can also with the pin cup, the optional features such as castor are used in conjunction with, need not to increase subsidiary part, supporting leg 4 can be realized standardized designs, make.

Should be noted that at last; above content is only in order to illustrate the technical solution of the utility model; but not to the restriction of the utility model protection domain; the simple modification that those of ordinary skill in the art carries out the technical solution of the utility model or be equal to replacement does not all break away from essence and the scope of technical solutions of the utility model.
