Description

High Precision Automatic conveying equipment of weighing

Technical field

The utility model relates to a kind of High Precision Automatic conveying equipment of weighing, be applied to the industry such as warehouse logistics, manufacturing industry, be used in the accurate weight being arranged at the acquisition of the pipeline on two layers or multilayer flooring conveying articles, save its link of weighing, be convenient to the Efficient Operation of conveying equipment, increase work efficiency.

Background technology

At present, it is also few to be specifically designed to the equipment of high-precision weighing that pipeline that flooring installs uses, and when existing weighing-appliance is installed on the pipeline of multilayer flooring, weighting error is large, can not meet the demand of user; The main cause that its error produces is: the object that conveying equipment of weighing is weighed due to it is kept in motion, inevitably vibration is produced in motion process, thus easily produce resonance and affect weighing precision, therefore the intrinsic frequency how reducing conveying equipment self of weighing just has become a research direction improving weighing precision.

Utility model content

The utility model is for above-mentioned defect, and object is that providing a kind of reduces conveying equipment of weighing, thus improves the high accuracy building automatic Weighing conveying equipment of weighing precision.

The technical solution adopted in the utility model is for this reason: the utility model comprises support, is arranged on the LOAD CELLS on support, is arranged on the conveyer belt on LOAD CELLS top, establishes Weight plate between LOAD CELLS and support.

Buffer is established between described support and Weight plate.

Also Weight plate is established in the space formed between described LOAD CELLS and Weight plate.

The motorized pulleys driving conveyer belt are established between described LOAD CELLS and conveyer belt.

The utility model has the advantages that: 1) utilize the hardness of intrinsic frequency with it of object, size, quality relevant, the frequency that hardness is high is high, the principle that the large frequency of quality is low; Improve main structure body, increase the weight of base rack, thus reduce the intrinsic frequency of self, the impact of desalination resonance on weighing precision; Because the material of pipeline of weighing and size do not have too many improvement space, and the height of whole support adds that the height of drum conveying line will remain on same horizontal plane with other conveying equipments; If select the weight increasing support to reach reduction intrinsic frequency, so new production originally low support can only be compared, to obtain the height installing Weight plate; So when ensureing that whole height is constant, the support of new production is changed original support, and rubber blanket that 6MM is thick on four pin cup underlays of new support; The steel plate that 20MM that two pieces of its gross weights reach 186.9Kg is thick is installed on the top of support, has increased the deadweight of support, reduce the intrinsic frequency of self, effectively alleviated resonance that the environmental factors such as floor vibrations produce to the impact of weighing precision;

2) between support and steel plate, increase buffer, simplify the vibrations that surrounding environment causes further, eliminate the impact of resonance on weighing precision.Because buffer has the effect of damping, so we have installed the thick buffer of 40MM additional between support and steel plate, reduce the impact on steel plate of vibrations to a certain extent;

3) improve the installation site of LOAD CELLS, thus reduce the weighting error because the factors such as tare weight is excessive cause.4 original LOAD CELLSs be contained in support pin cup bottom, which results in the tare weight that whole line of weighing is all electronic scale, thus have impact on the precision of weighing.The more important thing is that such mounting means will cause 4 force acting on transducer there are differences because support four legs itself are difficult to ensure on same horizontal plane, thus produce error.Therefore, 4 LOAD CELLSs have been arranged on the Weight plate of 20MM by we, this ensures that there 4 sensors on the same face.And the motorized pulleys line be arranged on above sensor is an entirety, so just can ensure that force acting on transducer evenly also mitigates tare weight simultaneously, thus improve weighing precision;

4) motorized pulleys substitute motor as power original paper: first, and motor operation can produce vibrations, be exactly in weighing process motor out of service, this vibration also can not disappear at once, thus affects weighing precision.And motorized pulleys operate steadily, shake little alleviating to a great extent because the undesirable element of execution original paper generation is on the impact of weighing precision.Secondly, motorized pulleys are for motor, and its weight wants light and simple installation, not only can reduce tare weight but also Roller conveyor just can be arranged on LOAD CELLS very easily.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

1 be support, 2 be LOAD CELLS in figure, 3 be conveyer belt, 4 be Weight plate, 5 be buffer, 6 be motorized pulleys, 7 for pin cup.

Detailed description of the invention

The utility model establishes Weight plate 4 between LOAD CELLS 2 and support 1, and Weight plate 4 can be one piece of form, and also can be several pieces and assemble, the utility model preferentially selects the form of assembling, and to reduce, monolithic Weight plate 4 quality is convenient installs.

The utility model establishes buffer 5 in Weight plate 4 bottom simultaneously.

Also establish Weight plate 4 in the space that the utility model further can be formed between LOAD CELLS 2 and Weight plate 4, make full use of existing space, namely reach increase weight, simultaneously the not object that takes up room of increasing device again.

The utility model adopts motorized pulleys 6 to carry out driving conveyer belt 1, and motorized pulleys 6 are arranged on LOAD CELLS 2 top.

The utility model arranges pin cup 7 in support 5 bottom, and pin cup 7 is provided with cushion pad.
