Description

Tension detector with automatic packing box unfolding capability test function

The technical field is as follows:

the utility model relates to a have tensile force detector of automatic expansion capability test of packing carton concurrently.

Background art:

the packaging box needs to carry out tension detection on paper in the production process, and aims to detect whether the used paper meets the requirement of tension resistance. A paper tension detector is specially designed for the manufacturer, but the traditional paper tension detector can only detect the tensile resistance of paper, and the function is single. The packaging box needs to detect the tensile resistance of paper and the unfolding capability of the packaging box, and most of packaging box wrapping products are carried out in full-automatic equipment at present, so that the packaging box needs to be unfolded easily and maintain a box-shaped unfolding state reliably after being unfolded. The main factor influencing the unfolding difficulty and reliability of the packing box is the crease characteristic in the manufacturing process of the packing box, the packing box can be easily unfolded due to too large pressure of pressing the crease, but the box-shaped strength is not enough after the box is unfolded, the box is difficult to unfold due to too small pressure, and at present, no detection equipment specially aiming at the unfolding performance of the packing box exists.

The utility model has the following contents:

the utility model aims at overcoming the shortcoming of above-mentioned prior art, provide a have the tensile force detector of the automatic expansion capability test of packing carton concurrently.

The purpose of the invention of the utility model can be realized by the following technical scheme: the utility model provides a have tensile force detector of automatic expansion capability test of packing carton concurrently, including frame, elevating gear, fixed paper holder and lift paper holder, lift paper holder installs on elevating gear, and fixed paper holder is fixed in the frame and is located the below of lift paper holder, is provided with the tension sensor in the frame inside, is provided with V-arrangement paper pressing member at the top of lift paper holder, correspondingly is provided with the fixed paper pressing member of falling V-arrangement in the top of V-arrangement paper pressing member.

The lifting device comprises a screw rod, a servo motor and a lifting piece, the screw rod is arranged in the frame, the screw rod is installed on the servo motor, the lifting paper holder is provided with the lifting piece, and the lifting piece is connected to the screw rod in a penetrating mode and forms threaded fit with the screw rod.

The fixed paper clamping device and the lifting paper clamping device are the same in structure and comprise a machine base, a left clamping block and a right clamping block, the machine base is installed on a lifting piece, the left end of the machine base is fixedly provided with the left clamping block, the right end of the machine base is connected with a screw in a penetrating mode, the right clamping block is arranged at the front end of the screw, and the screw is rotated to control the right clamping block to move left and right.

After adopting this technical scheme, compare with prior art, this technical scheme has following advantage: the test of the automatic expansion performance of the packaging box is added on the basis of the original tension detector, the function of the tension detector is added, the modification cost is low, and the detection is reliable.

Description of the drawings:

fig. 1 is a structural diagram of the tension detector of the present invention.

The specific implementation mode is as follows:

the present technology is further described below with reference to the accompanying drawings.

The tensile testing appearance that has packing carton automatic expansion ability test concurrently of this embodiment, including frame 1, elevating gear, fixed paper holder 2 and lift paper holder 3, fixed paper holder 2 is the same with lift paper holder 3 structure, including frame 4, left clamp splice 5 and right clamp splice 6, frame 4 is installed on lift 7, the left end of frame 4 is fixed to be set up left clamp splice 5, the right-hand member has worn to connect screw 8, right clamp splice 6 sets up at the 8 front ends of screw, back and forth movement about the right clamp splice 6 of 8 control of rotating screw. The lifting paper holder 3 is arranged on a lifting device, the fixed paper holder 2 is fixed on the frame 1 and is positioned below the lifting paper holder 3, a tension sensor (the common knowledge technology is not marked in the figure) is arranged in the frame 1, the V-shaped paper pressing piece 9 is arranged at the top of the lifting paper holder 3, the V-shaped paper pressing piece 9 and the lifting paper holder 3 lift together, and correspondingly, the inverted V-shaped fixed paper pressing piece 10 is arranged above the V-shaped paper pressing piece 9. The lifting device comprises a screw rod 11, a servo motor 12 and a lifting piece 7, the screw rod 11 is arranged in the rack 1, the screw rod 11 is installed on the servo motor 12, the lifting paper holder 3 is installed on the lifting piece 7, and the lifting piece 7 penetrates through the screw rod 11 and forms threaded fit with the screw rod 11. The servo motor 12 is started to drive the screw rod 11 to rotate, the lifting piece 7 is driven to lift, and the lifting paper holder 3 arranged on the lifting piece 7 and the V-shaped paper pressing piece 9 lift together.

When the tensile resistance of the paper needs to be detected, the screws 8 on the fixed paper holder 2 and the lifting paper holder 3 are unscrewed, the screws 8 drive the right clamping block 6 to retreat away from the left clamping block 5, then the lower end of the paper is placed between the left clamping block 5 and the right clamping block 6 on the fixed paper holder 2, the upper end of the paper is placed between the left clamping block 5 and the right clamping block 6 on the lifting paper holder 3, then the screws 8 on the fixed paper holder 2 and the lifting paper holder 3 are rotated to move the right clamping blocks 6 at the two positions to the left clamping block 5, finally the paper is clamped, then the servo motor 12 is started to enable the screw rod 11 to drive the lifting piece 7 and the lifting paper holder 3 to ascend, the paper is pulled in the ascending process, the tensile force sensor senses the tensile force of the lifting paper holder 3 in the ascending process, the maximum tensile force data obtained when the paper is pulled apart is obtained, and therefore the tensile resistance of the paper is obtained.

When the unfolding performance of the packing box needs to be detected, the packing box is placed between an inverted V-shaped fixed paper pressing piece 10 and a V-shaped paper pressing piece 9 which are positioned above the tension detector, then a servo motor 12 is started to rotate a screw rod 11 to drive a lifting piece 7, a lifting paper holder 3 and the V-shaped paper pressing piece 9 to ascend, the packing box is oppositely pressed together with the inverted V-shaped fixed paper pressing piece 10 fixed above the tension detector along with the ascending of the V-shaped paper pressing piece 9, the packing box is opened, a tension sensor acquires the pressure in the opposite pressing process, a tester is enabled to master pressure data, if the packing box is successfully opened, the packing box is proved to be suitable for being used on an automatic packing machine, however, if the packing box is failed to be opened, namely the packing box is not opened and is bent, the pressure for pressing each turn of the packing box is required to be adjusted in the indentation process, then the, obtaining the optimal pressing force of the indentation for large-scale production of the packaging box.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention in any way. The invention is not limited to the embodiments described herein, but is capable of other embodiments with obvious modifications and variations, including those shown in the drawings and described herein.
