Abstract

The utility model relates to a testing device for the stripped strength of the uppers and the soles of the shoes. During the process of the detection, the tested shoes is forced by an operator directly, the peeling strength value can be indicated through a dial indicator by utilizing the elastic deformation of a measuring force piece to test the shoes whether achieve the requirement of the product standard, and therefore, the quality of the shoes can be known and controlled in time. The utility model has the advantages of simple structure, low cost, convenient operation and stable quality. Besides, the utility model is suitable for all shoe-making factories.

Description

Testing device for shoes stripped strength

The utility model relates to a kind of testing arrangement that becomes footwear upper of a shoe and sole peel strength.

Peel strength is an important indicator that is controlled to the footwear quality, so stripping off device is one of indispensable checkout equipment of one factory.

At present have electrically and manually two kinds to peel off testing arrangement in order to what test this index, but its service condition strictness, complicated operation, therefore the cost height is popularized in medium-sized and small enterprises and is remained in certain difficulty.

Along with developing rapidly of shoemaking industry, more and more higher to quality requirement, this just needs a kind of low price, simple to operate, the miniaturization testing arrangement that can in time detect, reflect at any time quality situation in the production process.

The utility model aims to provide a kind of simple in structure, cheap, easy and simple to handle, can reflect the checkout gear of product quality simultaneously again soon.

The testing arrangement of one-tenth footwear upper of a shoe of the present utility model and sole peel strength comprises shown in schematic diagram at least:

(1) dynamometry sheet (elastomer) 1, its end is rigidly connected with the supporting station 4 that is positioned on the base plate 9, and its distortion is stressed linear with institute;

(2) hoe scaler 2, are rigidly connected with an end of 1, and its edge of a knife is positioned at 1 neutral line;

(3) amesdial 3, are connected with 4, be positioned at 1 directly over and have point of contact with it;

(4) supporting station 4, are positioned at the end on base plate 9 planes, and is rigidly connected with base plate 9;

(5) bearing 5 slidably is positioned at 1 below, on the base plate 9, can be with respect to sliding before and after the dynamometry leaf length direction, and adjusting the distance between adjustable support 6 and the edge of a knife 2, and there is fixture 7 to make it not come off or will ly fixes;

(6) adjustable support 6, are connected with 5, wherein have with respect to hoe scaler edge of a knife adjusting device 8 up and down;

(7) base plate 9, and it is the plummer of whole device.

The available steel of whole device are made, and dynamometry sheet 1 adopts spring steel, requires quenching hardness suitable, and the distortion when making the dynamometry sheet stressed has favorable linearity, its deviation from linearity≤3%.

Hoe scaler directly contacts with tested one-tenth footwear, and the power that it is suffered is delivered on the dynamometry sheet during detection.

Amesdial 3 is primary instruments of measuring dynamometry sheet deformation values, and the dial plate indicating value is a long measure, and each little lattice is 1 μ m.When manually forcing in the band shoe last or hat block when becoming on the footwear, the dynamometry sheet produces strain, amesdial shows the deformation values of dynamometry sheet, because power value and deformation values are linear relationships, therefore suitably select the installation site of amesdial, make the i.e. little lattice of tabular value 1 μ m() corresponding to power value 1N, can directly read the power value by amesdial.

Supporting station 4 is fixed on the base plate 9, is the end that is rigidly connected of dynamometry sheet and amesdial table shaft bar, and the linear deformation when guaranteeing that the dynamometry sheet is stressed and the error of indication of amesdial drop to minimum.

Adjustable support 6 can be adjusted its height by sole thickness in order to the supporting sole, guarantees that the normal angle when measuring is 5 °-10 °.

The method of operating of this testing arrangement:

1. rotate the dial plate of amesdial 3, the minute hand of amesdial is transferred to " 0 " position.

2. place footwear by Fig. 2, and according to sole thickness and size adjust adjustable support 6 height and and hoe scaler 2 between distance, make sole and support contact point and peel off distance 〉=50mm between the edge of a knife, sole inclination angle with respect to the horizontal plane is between 5 °-10 °, and hoe scaler is aimed at the tested position of footwear.

3. slowly depress the other end of footwear with hand reposefully, observe amesdial pointer indication dial plate indicating value simultaneously, amesdial 3 shows dynamometry sheet deformation values, is peeling force value (N).Because designed to peel off the edge of a knife wide 1 centimetre, peel strength value (N/Cm) equates with the numerical value of peeling force value.When tabular value reaches the peel strength value of product standard regulation, whether occur coming unglued between observation upper of a shoe and the sole, not come unglued, come unglued for defective for qualified.

Technical indicator: peak load 400N

Stripper edge of a knife width 10 ± 0.1mm

Dynamometry sheet deviation from linearity≤3%

Instrument deviation of reading≤3%

Instrument tolerance between forward and backward in indicating value 8%

The characteristics of this testing arrangement are:

1. volume is little, and in light weight is the most outstanding in the like product.

2. simple to operate, use flexibly, conveniently moving is not subjected to the restriction of environmental condition, can be used on inter process workman self check and inspector check.

By its structures shape product price cheap, no matter large or small enterprise or individual industrialists and businessmen can both bear, and are easy to ensure the quality of products.

4. unpowered and transmission device.

In order to be illustrated more clearly in the utility model, enumerate following examples, but its to scope of the present utility model without any restriction.

Example 1

This testing arrangement is shown in Figure 1 as illustrating, comprising:

Dynamometry sheet 1 adopts long 170-175 millimeter, the spring steel of wide 20-25 millimeter, and the one end is rigidly connected by bolt and supporting station 4, and the other end is connected with hoe scaler.

Hoe scaler 2, long 30-35 millimeter, wide 10 millimeters, rigidly connected with dynamometry sheet one end, the edge of a knife is positioned at the neutral line of dynamometry sheet.

Amesdial 3 meets the commercially available prod of national standard, and is rigidly connected by table bar and support and supporting station 4, is positioned at the top of dynamometry sheet.As illustrate shown in Figure 1ly, be the 120-130 millimeter from table shaft bar left end to table bar right-hand member total length.Amesdial and dynamometry sheet have point of contact.

Supporting station 4 is the square object of one (45-50) * (45-50) * (25-30) millimeter, and is rigidly connected in base plate by bolt.

Slidably bearing 5, and the available angle steel is made, on base plate, and its long 80-85 millimeter, the wide width that is a bit larger tham base plate has fixture 7 to make it to be positioned at not come off on the base plate and slidably in the base plate side.

Adjustable support 6 is a long 25-30 millimeter, the cylinder of external diameter 12-15 millimeter, and its top is a hemispherical, the bottom is the plane, is arranged in bearing end slidably and makes it the device that moves up and down only, can make it to raise in cylinder lower end shimming.

Tunable arrangement 8 is thick 1,2 or 3 millimeter, 20 * 30 millimeters long square washers.

Base plate 9, long 260-285 millimeter, wide 160-180 millimeter, thick 15-20 millimeter.

It is device of the present utility model that the parts of above-mentioned size are fitted together by described connected mode.Whole device need be purchased the commercially available prod that meets national standard in addition except that amesdial, and available steel are made, but its surface baking vanish or chromium plating.
