Description

Quick inspection tool for detecting photo paper cores

technical field

The utility model relates to an inspection tool, in particular to a quick inspection tool for detecting the core of photographic paper.

Background technique

Since our company produces expanded printing roll paper, the paper core is provided by the supplier. During the use of the customer after the product leaves the factory, it will be found that some batches of product paper cores have unqualified inner diameters. In this case, we will The inner diameter of the paper core provided by the supplier must be fully inspected or partially inspected.

The general method is to use calipers to measure one by one. Due to the large quantity, it is very troublesome to measure and read in this way. After a long time, people are prone to fatigue, and the accuracy of measurement is greatly reduced. In short, it is labor-intensive and time-consuming, and the error rate is also high.

Utility model content

The purpose of the utility model is to overcome the defects of the prior art and provide a quick inspection tool for detecting the core of photographic paper.

In order to achieve the above object, the utility model adopts the following technical solutions:

The rapid inspection tool for detecting the core of photographic paper includes a base plate and two semicircular blocks arranged on the base plate; the base plate is provided with two elongated grooves, and the lower side of the base plate is provided with two through A screw with an elongated groove and a half-circle block threaded connection.

Preferably, four foot pads are provided on the lower side of the bottom plate.

Preferably, the lower end of the semicircular block is provided with a square protrusion embedded in the elongated groove.

Preferably, at least one semicircular block is provided with more than two square grooves on the inner surface; and a square measuring block arranged in the square groove is also included.

Preferably, the square gauge block is a magnetic iron block.

Preferably, the width of the square gauge block is less than one-fifth to one-tenth of the height.

Preferably, the upper, lower, left and right four surfaces of the square gauge block are provided with embedded magnetic pieces.

Compared with the prior art, the utility model has the beneficial effects that: the utility model adopts two adjustable semicircular blocks fixed on the bottom plate, which can form different sizes of inner diameter snap gauge structures, and when used for the inspection of the inner diameter of the paper core, the effect Well, the inspection efficiency and accuracy have been improved; compared with the inspection with calipers, the inspection efficiency has increased by more than five or six times. There are square grooves of different depths on the inner surface of the semicircular block and square gauge blocks in the square grooves, which can quickly form different sizes of inner diameter caliper structures, so that the inner diameter caliper structures can be quickly adjusted and the adjustment efficiency is improved.

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.

Detailed ways

In order to fully understand the technical content of the utility model, the technical solutions of the utility model will be further introduced and illustrated below in conjunction with specific examples, but not limited thereto.

In conjunction with Fig. 1 and 2, understand the concrete content of the present utility model. The utility model is used for detecting the rapid inspection tool of photographic paper core, comprises base plate 10 and two semicircle blocks 20 that are arranged on base plate 10; Two screws 30 threaded through the elongated groove 11 and the semicircular block 20 . The underside of base plate 10 is provided with four foot pads 40 (can be placed on the workbench during use, prevents sliding). In order to prevent the rotation of the semicircular block, a square protrusion (not shown) embedded in the elongated groove 11 is provided at its lower end.

In another embodiment shown in FIG. 3 , three square grooves 21 (with different depths) are provided on the inner surfaces of the two semicircular blocks 20A;

In other embodiments, the square measuring block is a magnetic iron block, and the two can be fixed through magnetism. The specific structure can be in the form of embedding magnetic sheets on the surface, for example, embedded magnetic sheets are arranged on the upper, lower, left and right four surfaces of the square gauge block.

In other embodiments, the width of the square measuring block can be less than one-fifth to one-tenth of the height, and by rotating 90 degrees, different diameters of the caliper can be realized, and the purpose of testing products with different inner diameters can be achieved.

In summary, the utility model adopts two adjustable semicircular blocks fixed on the bottom plate, which can form different sizes of internal diameter snap gauge structures, and when used for the inspection of the inner diameter of the paper core, the effect is good, and the inspection efficiency and accuracy are improved. ;Compared with caliper inspection, the inspection efficiency has been improved by more than five or six times. There are square grooves of different depths on the inner surface of the semicircular block and square gauge blocks in the square grooves, which can quickly form different sizes of inner diameter caliper structures, so that the inner diameter caliper structures can be quickly adjusted and the adjustment efficiency is improved.

The above only uses examples to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation of the utility model is limited to this, and any technical extension or re-creation done according to the utility model shall be Protected by the utility model. The scope of protection of the utility model shall be determined by the claims.
