Description

Technical Field

[0001] This utility model relates to the field of thickness detection technology, and in particular to a corrugated cardboard thickness detection device. Background Technology

[0002] Corrugated cardboard, also known as corrugated paperboard, is made of at least one layer of corrugated paper and one layer of linerboard bonded together. It possesses good elasticity and extensibility. It is mainly used in the manufacture of cartons, carton fillings, and other packaging materials for fragile goods. The corrugated waves of the cardboard resemble interconnected arches, arranged side-by-side and supporting each other to form a triangular structure. This provides good mechanical strength, allowing it to withstand a certain amount of pressure on a flat surface, and its elasticity provides excellent cushioning. Corrugated cardboard has a wide range of applications, resulting in strong market demand and large-scale production.

[0003] To better control the quality of corrugated cardboard produced, factories sample some cardboard for thickness testing to determine if the thickness meets standards. However, when inspecting the thickness, factories typically only use calipers to measure the edges. Calipers cannot be used on the center of the cardboard, leading to significant errors in the measurement results. This method is ineffective in assessing the production quality and hinders strict quality control. Utility Model Content

[0004] The purpose of this application is to provide a corrugated cardboard thickness testing device to solve the problem mentioned in the background art that when factories conduct random inspections of the thickness of corrugated cardboard, they generally only use calipers to measure the thickness at the edges. The calipers cannot be used to measure the thickness of the middle part of the corrugated cardboard, resulting in a large error in the test results. This makes it impossible to effectively judge the production quality of the corrugated cardboard and is not conducive to the strict control of the production quality of corrugated cardboard.

[0005] To achieve the above objectives, this application provides the following technical solution: a corrugated cardboard thickness detection device, comprising a frame, a horizontal plate fixed on the frame, and a movable traction assembly installed on the frame. Two first carrier tubes arranged in parallel are installed on the movable traction assembly, and the movable assembly is used to drive the two first carrier tubes to move synchronously. A second carrier tube is slidably inserted into the bottom of the first carrier tube, and a U-shaped seat is fixed to the bottom of the second carrier tube. Rollers are rotatably connected between the front and rear inner walls of the U-shaped seat via bearings. A top plate is fixed to the top of the second carrier tube, and an indicator light is installed on the lower part of the top plate. The second carrier tube is sleeved around the indicator light. Two power-on pins are installed on the upper part of the top plate. A stud is inserted into the top of the first carrier tube, and the first carrier tube is threadedly connected to the stud. A carrier plate is rotatably connected to the bottom end of the stud via bearings. The carrier plate slides against the inner wall of the first carrier tube, and two power-supply pins are installed on the lower part of the carrier plate. When the two power-on pins contact the two power-supply pins, the indicator light is energized and illuminates.

[0006] Furthermore, a knob is fixed to the top of the stud.

[0007] Furthermore, a storage battery is installed on the back of the first carrier cylinder, which is used to power the indicator light.

[0008] Furthermore, two limiting rods are fixed on the second carrier cylinder, and a limiting groove adapted to the limiting rods is provided on the first carrier cylinder.

[0009] Furthermore, a reinforcing plate is fixed between the frame and the cross plate.

[0010] Furthermore, the mobile traction assembly includes a rectangular frame plate, which is fixedly mounted on the frame and located directly above the horizontal plate. A lead screw is rotatably connected between the left and right inner walls of the rectangular frame plate via bearings. A lead screw nut is mounted on the lead screw, and a carrier block is mounted on the lead screw nut. The carrier block slides against the inner wall of the rectangular frame plate, and a support plate is fixed to the bottom of the carrier block. Two fixing plates are fixed to the bottom of the support plate, and the two first carrier cylinders are respectively mounted on the two fixing plates. A drive motor is mounted on the right side of the rectangular frame plate, and the lead screw is driven by the drive motor.

[0011] Furthermore, a guide rod is fixed between the left and right inner walls of the rectangular frame plate, and the carrier block is slidably sleeved on the outside of the guide rod.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] 1. In this utility model, by turning the knob, the stud can be rotated, causing the stud to pull the carrier plate to slide inside the first carrier cylinder, thereby adjusting the distance between the bottom of the power supply pin and the top of the power receiving pin. The moving traction component pulls the roller to roll above the corrugated cardboard to be tested. Corrugated cardboard with the correct thickness will not trigger the indicator light on the right side to light up, nor will it cause the indicator light on the left side to go out. Corrugated cardboard with the incorrect thickness will show a different result. In this way, the detection result of the corrugated cardboard thickness is more accurate, and the detection of the corrugated cardboard thickness is more convenient and efficient.

[0014] 2. In this utility model, a drive motor is used to drive the lead screw to rotate, so that the lead screw drives the carrier block to move in a lead screw transmission manner. The carrier block moves together with the support plate and the fixed plate, thereby driving the two rollers to move, and then performing the inspection of corrugated cardboard.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example: Reference Figure 1-6 The corrugated cardboard thickness testing device shown includes a frame 1, a horizontal plate 2 fixed on the frame 1, and a movable traction assembly installed on the frame 1. Two first carrier tubes 3 arranged in parallel are mounted on the movable traction assembly, which drives the two first carrier tubes 3 to move synchronously. A second carrier tube 4 is slidably inserted into the bottom of each first carrier tube 3. Both the first and second carrier tubes 3 are made of transparent plastic. Two limiting rods 15 are fixed on the second carrier tube 4. Limiting grooves 16 adapted to the limiting rods 15 are formed on the first carrier tube 3. The cooperation between the limiting rods 15 and the limiting grooves 16 prevents the first carrier tube 3 from completely separating from the second carrier tube 4. A U-shaped seat 5 is fixed to the bottom of the second carrier tube 4, and the front and rear inner walls of the U-shaped seat 5 are rotatably connected by bearings. A roller 6 is connected to the top of the second carrier cylinder 4, and a top plate 7 is fixed to the top of the top plate 7. An indicator light 8 is installed on the lower part of the top plate 7. The second carrier cylinder 4 is sleeved on the outside of the indicator light 8. Two power-connecting pins 9 are installed on the upper part of the top plate 7. A stud 10 is inserted into the top of the first carrier cylinder 3, and the first carrier cylinder 3 is threadedly connected to the stud 10. A knob 14 is fixed at the top of the stud 10 to provide a force point. The bottom end of the stud 10 is rotatably connected to a carrier plate 11 through a bearing. The carrier plate 11 slides with the inner wall of the first carrier cylinder 3, and two power-supplying pins 12 are installed on the lower part of the carrier plate 11. A storage battery 13 is installed on the back of the first carrier cylinder 3. The storage battery 13 is used to supply power to the indicator light 8. When the two power-connecting pins 9 and the two power-supplying pins 12 come into contact, the indicator light 8 is powered on and lights up.

[0025] Turning knob 14 rotates stud 10, causing stud 10 to pull carrier plate 11 to slide inside first carrier cylinder 3. This adjusts the distance between the bottom of power supply pin 12 and the top of power connection pin 9. The moving traction component pulls roller 6 to roll above the corrugated cardboard to be tested. Corrugated cardboard with the correct thickness will not trigger the indicator light 8 on the right side to light up, nor will it cause the indicator light 8 on the left side to turn off. Corrugated cardboard with the incorrect thickness will show a different result. In this way, the detection result of corrugated cardboard thickness is more accurate.

[0026] A reinforcing plate 17 is fixed between the frame 1 and the horizontal plate 2. The reinforcing plate 17 provides auxiliary support for the horizontal plate 2, making the horizontal plate 2 more stable when supporting the corrugated cardboard for testing.

[0027] The mobile traction assembly includes a rectangular frame plate 18, which is fixedly installed on the frame 1 and located directly above the horizontal plate 2. A lead screw 19 is rotatably connected between the left and right inner walls of the rectangular frame plate 18 via bearings. A lead screw nut is installed on the lead screw 19, and a carrier block 20 is installed on the lead screw nut. The carrier block 20 slides with the inner wall of the rectangular frame plate 18, and a support plate 21 is fixed to the bottom of the carrier block 20. Two fixing plates 22 are fixed to the bottom of the support plate 21, and two first carrier cylinders 3 are respectively installed on the two fixing plates 22. A drive motor 23 is installed on the right side of the rectangular frame plate 18, and the lead screw 19 is driven by the drive motor 23. A guide rod 24 is fixed between the left and right inner walls of the rectangular frame plate 18, and the carrier block 20 is slidably sleeved on the outside of the guide rod 24.

[0028] The drive motor 23 drives the lead screw 19 to rotate, so that the lead screw 19 drives the carrier block 20 to move in the form of lead screw transmission. The carrier block 20 moves together with the support plate 21 and the fixed plate 22, thereby driving the two rollers 6 to move, and then performing the corrugated cardboard inspection work. The guide rod 24 is set to share the force of the lead screw 19 and improve the stability of the carrier block 20 when it moves.

[0029] Working principle of this utility model:

[0030] First, take out the corrugated cardboard to be tested and lay it flat on the horizontal plate 2. The thickness of this corrugated cardboard is tentatively set as X, and the allowable error is Y. After multiple experiments, the average value is taken to find that the depth of the corrugated cardboard being squeezed by the roller 6 when it rolls is Z. The staff first turns the knob 14 on the left side to make it drive the stud 10 to rotate. The stud 10 pulls the carrier plate 11 to slide inside the first carrier cylinder 3, thereby adjusting the distance between the bottom of the power supply pin 12 and the top of the power receiving pin 9, so that the vertical distance between the two is controlled as XYZ. Then, the staff turns the knob 14 on the right side to adjust the vertical distance between the bottom of the right power supply pin 12 and the top of the power receiving pin 9 to X+YZ, thus completing the preparation work.

[0031] When the drive motor 23 is powered on, it drives the lead screw 19 to rotate. The lead screw 19 drives the carrier block 20 to move to the right via lead screw transmission. The carrier block 20 pulls the two rollers 6 to move, so that the two rollers 6 roll onto the corrugated cardboard to be tested. If the thickness of the corrugated cardboard meets the requirements, the left indicator light 8 should always be lit, and the right indicator light 8 should always be off. If there is a deviation from this result, the thickness of the corrugated cardboard can be determined to be unqualified. In addition, the operator can change the test position of the corrugated cardboard to make it possible to use this device to test the same corrugated cardboard multiple times, so as to improve the accuracy of the test results.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
