Abstract

The utility model discloses a chain plate type electronic weighing scale which belongs to a weighing apparatus. While in use, a belt type electronic weighing scale is changed to a chain plate type electronic weighing scale; a chain plate, a charging plate and a connecting pin are used to form a plate type chain, and the plate type chain is used as a pulling and bearing member; a wedge type block is fixed to the lower part of the plate type chain, the wedge type block is embedded into a V-shaped slot, and the V-shaped slot uses V-shaped slot wheels as a driving wheel and a bend wheel; thereby, the plate type chain is driven to convey the flowing material, and the flow quantity can be transferred and shown by a sensor and a secondary meter when the flowing material passes through a metering section. The utility model has high precision, stable running, etc. The utility model can do weighing for the flowing material of high-temperature and big abrasion ability.

Description

Chain plate type electronic weighing scales

A kind of weighing instrument is applicable to the weighing of continuous flow material when flowing, especially applicable to the weighing of high temperature, continuous flow material that chiseling property of mill is bigger.

The instrument of existing weighing continuous flow material, use the belt-type electronic scales mostly, it is as conveying belt and bearing carrier with balata belt, by driving wheel and bend wheel, the fastness that produces between dependence belt and the two-wheeled transmits moment of torsion and turns round, but this belt-type electronic scales is when using the higher temperature flowable materials, because the balata belt heat resistance is poor, easily burn at a certain temperature, and, for the sharp hard Flow of Goods and Materials in particle corner, rubber conveyer belt is extremely wearing and tearing again, serviceable life is shorter, therefore, adopt balata belt to come weighing high-temperature material or the bigger material of chiseling property of mill to be subjected to certain restriction as the traction and the bearing carrier of electronic scales, for addressing the above problem, adopted various chains as driving component on the electronic scales that has, its driving wheel on head and bend wheel generally adopt toothed wheel or polygonal wheel, rely on the engagement of sprocket to force to transmit moment of torsion, but this sprocket-type electronic scales is owing to inevitably making, install the generation error, wearing and tearing are bigger in the operation process, but also because the sprocket transmission is to rely on engagement to force transmission, its galloping, thereby be difficult to satisfy the accuracy requirement of electronic scales.

The purpose of this utility model is exactly in order to overcome the deficiency of above-mentioned existence, provide a kind of can weighing high temperature or the bigger flowable materials of chiseling property of mill, can turn round again steadily, satisfy the weighing instrument of accuracy requirement.

The utility model is achieved by the following technical solution, promptly adopt leaf chain as traction and bearing carrier, it is made up of carrier bar, charge plate and connecting pin, be fixed with one group of wedge in the bottom of two carrier bars, as driving wheel and bend wheel, wedge is embedded in the groove with the V-type sheave, utilizes the flowable materials on the fastness transmission moment of torsion drive charge plate, gone out signal through a metering section by sensor passes, thereby carry out weighing by secondary instrument.

Description of drawings is as follows:

Fig. 1 is a carrier bar structural representation of the present utility model,

Fig. 2 is a drives structure synoptic diagram of the present utility model,

Fig. 3 is a structural representation of the present utility model.

Below by accompanying drawing the utility model is done more detailed the introduction: see Fig. 1, with carrier bar 1, the leaf chain that charge plate 2 and connecting pin 3 are formed is as traction and bearing carrier 6, and charge plate 2 is fixed on the top of leaf chain, is fixed on the bottom of leaf chain in addition with wedge 4; Wedge 4 directly is embedded in and adopts in the V-shaped groove of V-type sheave 5 as driving wheel among Fig. 2, drives bearing carrier 6 operations by friction torque.Driving wheel and bend wheel all adopt V-shaped groove wheel 5 among Fig. 3, split two ends in frame 10, one group of wedge 4 on the leaf chain 6 directly contacts with the V-shaped groove of driving wheel with bend wheel 5, be provided with several fixed guides 7 at the haul section, and intercept certain length as metering section 8, and these metering section 8 places are provided with sensor 9, and sensor 9 is converted into electric signal output with force signal, through secondary instrument or Computer Processing, directly demonstrate the flow of the flowable materials that passes through.For the V-arrangement race is worn and torn equably, be unlikely because sprocket wheel wearing and tearing back produces galloping, influence precision, the pitch circumference of driving wheel and chain pitch be prime number each other, thereby make contact point constantly change, the bend wheel of wedge 4 in V-shaped groove wheel 5 identical with driving wheel, its pitch circumference and chain pitch be prime number each other.

The utlity model has the precision height, the life-span is long, smooth running, and energy weighing high temperature, the big characteristics such as flowable materials of chiseling property of mill.

Claims

1, a kind of weighing instrument, it drives traction and bearing carrier 6 runnings by driving wheel on the frame 10 and bend wheel 5, flowable materials is through bearing carrier 6 motions, behind metering section 8, its flow transmits and shows through secondary instrument by sensor 9, it is characterized in that described traction and bearing carrier are by carrier bar 1, the leaf chain that charge plate 2 and connecting pin 3 are formed constitutes, the structure of driving wheel and bend wheel 5 is the V-shaped groove wheel, wedge 4 is embedded in the V-type groove, transmits moment of torsion to drive traction and bearing carrier by each other fastness.

2, weighing instrument as claimed in claim 1 is characterized in that the pitch circumference of described driving wheel and bend wheel 5 and carrier bar pitch prime number each other.
