Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper detection, in particular to a corrugated paper detection workbench. Background Art

[0002] Corrugated paper is a cardboard material formed by embossing multiple layers of cardboard. It is usually composed of three layers. The outer layer of cardboard is called face paper, and the two inner layers of cardboard are called corrugated core paper. Corrugated paper adopts a wavy design, which provides better strength and compression resistance. Corrugated paper is widely used in carton manufacturing, packaging materials, printed packaging and other industries.

[0003] After the corrugated paper is produced, it needs to be inspected for quality. Compression testing is one of the inspection items to ensure that the corrugated paper can withstand the pressure and gravity during transportation and storage. The existing method of compressive testing of corrugated paper is mainly to press the corrugated paper with a handheld press, apply the required pressure on the corrugated paper according to the reading of the pressure sensor on the press, and observe whether the corrugated paper is damaged or excessively dented in the compressed area after a period of time. However, during the above-mentioned detection method, due to the lack of positioning of the corrugated paper, the corrugated paper is prone to displacement when under pressure. In addition, the handheld press force detection has large human errors, making it difficult to ensure the accuracy of the detection. Utility Model Content

[0004] The utility model aims to provide a corrugated paper detection workbench with good positioning effect and high detection accuracy, which effectively solves the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions.

[0006] A corrugated paper inspection workbench comprises a base, two clamping blocks are installed above the base through a first driving mechanism arranged on the base, the first driving mechanism is used to drive the two clamping blocks to move away from or closer to each other, a stand is vertically fixed to the rear side of the upper surface of the base, a cantilever is fixed to the top of the stand, a guide hole is vertically passed through the cantilever, a guide rod is slidably installed in the guide hole, a pressure plate is installed at the bottom end of the guide rod, a second driving mechanism is provided on one side of the cantilever, and the second driving mechanism is used to drive the guide rod to be raised and lowered.

[0007] It can be seen that by operating the first driving mechanism, the two clamps are driven to approach each other until the corrugated paper sample is clamped, so as to achieve the positioning effect, and prevent the corrugated paper from being offset by force and affecting normal detection. The utility model limits the guide rod through the guide hole, and can drive the guide rod to rise and fall in the vertical direction by operating the second driving mechanism, so as to ensure that the direction of pressure applied to the corrugated paper sample is consistent downward each time. Combined with the positioning effect of the corrugated paper sample, the consistency of detection of different corrugated paper samples is maintained, and the utility model is highly practical. Compared with the traditional manual handheld detection method, the detection accuracy is high and the error is small.

[0008] Furthermore, the base is provided with a guide groove extending along its length direction, and the first driving mechanism includes a bidirectional threaded rod rotatably installed in the guide groove, two nut seats limitedly slidably installed in the guide groove, and a first rocker, the two nut seats are respectively threadedly matched and mounted on both sides of the bidirectional threaded rod, the two clamping blocks are respectively fixed on the top of the nut seats, one end of the bidirectional threaded rod extends through the side of the base, and the first rocker is installed on the outer end of the bidirectional threaded rod.

[0009] By shaking the first shaking plate forward and reversely, the bidirectional threaded rod is driven to rotate in the guide groove. The rotating guide groove engages and drives the two nut seats to move closer to or away from each other in the guide groove, thereby driving the two clamping blocks to move closer to each other to achieve clamping positioning or move away from each other to achieve clamping release.

[0010] Furthermore, the second driving mechanism includes a connecting arm fixed to one side of the top end of the guide rod, a rack vertically fixed below the connecting arm, an axle rod rotatably installed on the side of the cantilever through a first bracket, a gear and a worm wheel fixedly sleeved on the axle rod, and a worm gear rotatably installed above the cantilever through a second bracket fixed above the cantilever, the gears are meshingly connected with the rack, the worm gear is meshingly connected with the rack, and a second rocker is installed on the end of the worm gear.

[0011] The worm is driven to rotate by shaking the second rocking plate in both directions. The rotating worm meshes with the worm wheel and drives the shaft and gear to rotate. The rotating gear can mesh with the driving rack to move up and down. Under the fixed connection of the connecting arm, the guide rod can be driven to rise and fall synchronously, thereby providing a stable drive for the rise and fall of the guide rod and the pressure plate. The drive adjustment is carried out by the worm meshing with the worm wheel. The transmission of the worm and the worm wheel has a one-way effect, thus achieving a self-locking effect. When the second rocking plate is not shaken, the guide rod is ensured not to rise and fall at will, which helps to maintain the state of the pressure plate and facilitates the detection operation.

[0012] Furthermore, a pressure sensor is embedded in the bottom of the pressure plate, the pressure-bearing surface of the pressure sensor is flush with the lower surface of the pressure plate, and a display is provided on the upper surface of the base, which is electrically connected to the pressure sensor.

[0013] When the corrugated paper sample is pressed under the pressure plate, the pressure sensor will contact and squeeze the corrugated paper sample. At the same time, the pressure sensor will collect the pressure data and transmit the data to the display for display, so that the staff can read the data and adjust the detection pressure to the required size.

[0014] Furthermore, a vertically extending detection ruler is fixed to the side of the stand, and the zero scale of the detection ruler is flush with the upper surface of the base. An indicator strip is fixed to the side of the pressure plate, and the lower surface of the indicator strip is flush with the lower surface of the pressure plate.

[0015] When the pressure plate just touches the top of the corrugated paper, the reading of the position indicated by the indicator bar on the side of the pressure plate on the detection ruler is the thickness of the corrugated paper, thereby realizing the detection of the thickness of the corrugated paper, so that the device can perform both corrugated paper compression resistance detection and corrugated paper thickness detection, killing two birds with one stone.

[0016] Furthermore, rubber pads are fixed to the opposite side surfaces of the two clamping blocks, and the rubber pads have anti-slip grooves.

[0017] By providing a rubber pad and providing anti-skid patterns on the rubber pad, the friction between the clamping block and the corrugated paper can be increased, thereby achieving an anti-skid effect and further improving the stability of the clamping of the corrugated paper.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0019] 1. The utility model places the corrugated paper sample above the base and between the two clamping blocks, and operates the first driving mechanism to drive the two clamping blocks to approach each other until the corrugated paper sample is clamped, thereby achieving a positioning effect, and the placed corrugated paper is subjected to force deviation and affects normal detection.

[0020] 2. The utility model limits and guides the guide rod through the guide hole, and can drive the guide rod to rise and fall in the vertical direction by operating the second driving mechanism, thereby ensuring that the direction of the pressure applied to the corrugated paper sample each time is consistently downward. Combined with the positioning effect of the corrugated paper sample, the consistency of the detection of different corrugated paper samples is maintained, and the utility model is highly practical. Compared with the traditional manual handheld detection method, the detection accuracy is high and the error is small.

[0021] 3. The utility model adopts the method of worm meshing and worm wheel rotation to drive and adjust. The transmission of the worm and worm wheel has a one-way effect, thereby achieving a self-locking effect. When the second rocking plate is not shaken, it ensures that the guide rod will not rise or fall at will, which helps to maintain the state of the pressure plate and facilitates detection operations.

[0022] 4. When the pressure plate of the utility model presses the corrugated paper sample, the pressure sensor will contact and squeeze the corrugated paper sample, and at the same time, the pressure sensor will collect pressure data and transmit the data to the display for display, so as to facilitate the staff to read and adjust the detection pressure to the required size. In addition, when the pressure plate just touches the top of the corrugated paper, the reading of the position indicated by the indicator bar on the side of the pressure plate on the detection ruler is the thickness of the corrugated paper, thereby realizing the detection of the thickness of the corrugated paper, so that the device can perform both the compression resistance test of the corrugated paper and the thickness test of the corrugated paper, killing two birds with one stone.
