Technical Field
[0001] This utility model relates to the technical field of paper flatness detection structure, and in particular to a paper flatness detection device for corrugated cardboard production. Background Technology
[0002] The paper smoothness testing device used in corrugated board production refers to the paper smoothness meter, also known as a smoothness tester. It is an instrument specifically designed to measure the surface smoothness of paper and paperboard. It is widely used in papermaking, packaging, printing, commodity inspection, scientific research and other departments, and is one of the important indicators for evaluating paper quality.
[0003] The basic structural components of a paper smoothness tester mainly include a test head, a measurement system, an air path system, and a control system. In existing technologies, when testing paper smoothness with a paper smoothness tester, the paper needs to be placed on the surface of the sample placement stage of the test head, and the test head is used for measurement. This method has several problems: first, there is no clamping structure, and the paper is too light, so it is easy to fly away and cause positional deviation; second, when measuring continuously, the position of the corrugated cardboard paper sample needs to be frequently adjusted manually. Utility Model Content
[0004] The main purpose of this utility model is to provide a paper flatness detection device for corrugated cardboard production, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A paper flatness testing device for corrugated cardboard production includes a smoothness meter body. Two grooves are formed on the upper surface of the smoothness meter body. A paper translation mechanism is movably installed inside each groove. A test head is fixedly installed at the center of the front end of the upper surface of the smoothness meter body. A printing outlet is provided near one end of the inclined surface of the smoothness meter body. A touch panel is embedded and fixedly installed near the other end of the inclined surface of the smoothness meter body. A start button is provided near the lower corner of the front surface of the smoothness meter body. A C-shaped support frame is fixedly installed at the front and rear ends of the lower surface of the smoothness meter body. A sponge pad is fixedly installed on the lower surface of the C-shaped support frame, and a rubber pad strip is fixedly installed on the lower surface of the sponge pad.
[0007] Preferably, there are two C-shaped support frames, sponge pads and rubber pads. The lower surface of the rubber pad has a transverse groove. The number of transverse grooves on the lower surface of the rubber pad is several, and the transverse grooves on the lower surface of the rubber pad are evenly distributed.
[0008] Preferably, the paper translation mechanism includes a bending slide, a C-shaped clamp, a triangular plate, a rubber strip, a screw, and an electric motor.
[0009] Preferably, the lower end of the bent sliding frame is inserted into the interior of the sliding groove.
[0010] Preferably, there are two C-shaped clips, which are fixedly installed at the middle of both ends of the bent sliding frame. There are two triangular plates installed on the outside of the C-shaped clips, which are fixedly installed at the upper and lower ends of the C-shaped clips. Rubber strips are fixedly installed at both the upper and lower ends of the C-shaped clips, and horizontal strips are fixed on the surface of the triangular plates.
[0011] Preferably, one end of the screw is inserted into the threaded through hole on the side of the bent slide frame.
[0012] Preferably, the electric motor is fixedly installed inside the slide groove at the front end, and the rotating shaft of the electric motor is fixedly connected to the other end of the screw.
[0013] This invention features a paper translation mechanism that can hold paper and automatically move paper samples used in corrugated cardboard production back and forth on the test head sample placement platform, which is beneficial for the smoothness meter to continuously measure the paper.
[0014] The C-shaped support frame, sponge pad, and rubber pads provide support, allowing operators to better lift the smoothness meter. The sponge pad makes the rubber pad fit the table better and also provides shock absorption. The rubber pads provide anti-slip properties, and the horizontal grooves on the lower surface of the rubber pads increase friction. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] like Figure 1-5 As shown, a paper flatness testing device for corrugated cardboard production includes a smoothness meter body 1. The upper surface of the smoothness meter body 1 has two grooves 2. A paper translation mechanism 3 is movably installed inside the grooves 2. A test head 4 is fixedly installed at the middle of the front end of the upper surface of the smoothness meter body 1. A printing outlet 5 is provided near one end of the inclined surface of the smoothness meter body 1. A touch panel 6 is embedded and fixedly installed near the other end of the inclined surface of the smoothness meter body 1. A start button 7 is provided near the lower corner of the front surface of the smoothness meter body 1. A C-shaped support frame 8 is fixedly installed at the front and rear ends of the lower surface of the smoothness meter body 1. A sponge pad 9 is fixedly installed on the lower surface of the C-shaped support frame 8. A rubber pad strip 10 is fixedly installed on the lower surface of the sponge pad 9. The paper translation mechanism 3 can clamp the paper and automatically move the paper sample for corrugated cardboard production back and forth against the sample placement platform surface of the test head 4, which is beneficial for the smoothness meter to continuously measure the paper.
[0023] In this embodiment, there are two C-shaped support frames 8, sponge pads 9, and rubber pads 10. The lower surface of the rubber pads 10 has horizontal grooves, and there are several horizontal grooves on the lower surface of the rubber pads 10. The horizontal grooves on the lower surface of the rubber pads 10 are evenly distributed. The C-shaped support frame 8 provides support, allowing the operator to better lift the smoothness meter body 1. The sponge pad 9 makes the rubber pads 10 fit the table more closely and has a shock-absorbing and cushioning effect. The rubber pads 10 have an anti-slip function, and the horizontal grooves on the lower surface of the rubber pads 10 increase the friction.
[0024] In this embodiment, the paper translation mechanism 3 includes a bending slide frame 301, a C-shaped clamp 302, a triangular plate 303, a rubber strip 304, a screw 305, and an electric motor 306.
[0025] In this embodiment, the lower end of the bent sliding frame 301 is inserted into the interior of the sliding groove 2, and the bent sliding frame 301 can slide within the sliding groove 2.
[0026] In this embodiment, two C-shaped clips 302 are provided. The C-shaped clips 302 are fixedly installed at the middle of both ends of the bending slide frame 301. Two triangular plates 303 are installed on the outside of the C-shaped clips 302. The triangular plates 303 are fixedly installed on the outside of the C-shaped clips 302 at the upper and lower ends. Rubber strips 304 are fixedly installed on both the upper and lower ends of the C-shaped clips 302. Horizontal strips are fixed on the surface of the triangular plates 303. The horizontal strips on the surface of the triangular plates 303 increase the friction. The C-shaped clips 302 can be opened by pinching the rear end of the triangular plates 303. The rubber strips 304 play a non-slip role to prevent the paper from slipping out of the C-shaped clips 302.
[0027] In this embodiment, one end of the screw 305 is inserted into the threaded through hole on the side of the bent slide frame 301.
[0028] In this embodiment, the electric motor 306 is fixedly installed inside the slide 2 at the front end. The rotating shaft of the electric motor 306 is fixedly connected to the other end of the screw 305. When testing the flatness of the corrugated cardboard, the C-shaped clamp 302 is pinched open by the rear end of the triangular plate 303 to clamp the two ends of the paper used for corrugated cardboard production. The start button 7 is pressed to turn on the smoothness meter body 1. The touch panel 6 is used for control. The electric motor 306 drives the screw 305 to rotate, so that the screw 305 enters and exits the threaded through hole of the bending slide frame 301, allowing the bending slide frame 301 to move along the slide 2, causing the paper to move and adhere to the sample placement platform surface of the test head 4, so that the test head 4 can perform continuous testing.
[0029] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
