Description

Technical Field

[0001] The present application relates to the field of equipment for testing the quality of plastic tarpaulins, and more specifically, to a device and process for testing the thickness of plastic tarpaulins. Background Art

[0002] As a key material widely used in warehousing, transportation, agriculture, and other fields, the uniformity of plastic tarpaulin's thickness directly impacts its waterproofness, tensile strength, and durability. Therefore, to ensure that the thickness of produced or purchased plastic tarpaulins meets quality requirements, relevant personnel often use plastic tarpaulin thickness testing devices to test the thickness of plastic tarpaulins.

[0003] The document with prior art publication number CN215114417U provides a spunlace non-woven fabric thickness monitoring device. The device can quickly determine the thickness of the spunlace non-woven fabric by setting up an installation shell, a laser rangefinder and a controller, making it convenient for staff to adjust the process parameters of the equipment, change the thickness, and achieve automatic fine adjustment.

[0004] While the aforementioned prior art solutions can achieve the relevant beneficial effects through existing structures, they still suffer from the following drawbacks: When using the aforementioned solutions to measure the thickness of a tarpaulin, the tarpaulin must be completely in contact with the metal plate to ensure accurate measurement. However, as the tarpaulin moves, a certain gap inevitably exists between the tarpaulin and the metal plate. Furthermore, the metal surface is likely to wear out after long-term use during movement, increasing the coefficient of friction, affecting the smooth passage of the fabric and potentially damaging it. Furthermore, the aforementioned solutions utilize airflow to promote contact, but this airflow may disturb the surface fibers of the fabric, affecting the accuracy of the laser rangefinder's readings. In light of these issues, we propose a device and process for measuring the thickness of plastic tarpaulins. Summary of the Invention

DETAILED DESCRIPTION

[0071] The present invention will be further described in detail below with reference to the accompanying drawings by way of examples of the present invention.

[0072] Reference Figures 1-10 The plastic tarpaulin thickness detection device disclosed in the embodiment of the present application includes: a thickness measuring mechanism, a placement rack 2, a conveying mechanism, a limiting mechanism, a correction component 5, a chip removal component 8 and an air injection component 9.

[0073] Among them, the thickness measuring mechanism is used to measure the thickness of the plastic tarpaulin. The thickness measuring mechanism includes an installation shell 1, a through slot 101 is provided on the installation shell 1, and laser rangefinders 10 are installed on the upper and lower sides of the installation shell 1; a supporting rod 17 is rotatably connected to one side of the placement frame 2, and one end of the supporting rod 17 is arranged in a T-shaped structure. A limiting slot is provided in the placement frame 2 to ensure that the supporting rod 17 is limited and rotated on the placement frame 2; the conveying mechanism is used to convey the plastic tarpaulin, and the conveying mechanism includes a first support frame 4 installed on one side of the installation shell 1, and two transmission rollers 3 are installed on the first support frame 4. A driving mechanism is also installed on one side of the first support frame 4, and the driving mechanism is used to drive the two transmission rollers 3 to rotate; the limiting mechanism includes a second support frame 14 installed on the other side of the installation shell 1, and two adjustment rollers 6 are installed on the second support frame 14; the correction component 5 is used to ensure that the tarpaulin located in the installation shell 1 is arranged in a horizontal structure; the chip removal component 8 is used to remove the raw material residue on the plastic tarpaulin; the air injection component 9 is used to blow air into the installation shell 1 to prevent external dust from invading and affecting the normal operation of the laser rangefinder 10.

[0074] A staff member secures the fabric roll onto the support rod 17, then sequentially passes one end of the fabric through the gap between the two adjustment rollers 6, the through slot 101, and the two transfer rollers 3. The adjustment roller 6 adjusts the pulled fabric to a horizontal position. Under the control of an external control mechanism, the drive mechanism operates, the two transfer rollers 3 rotate toward each other, and the fabric gradually enters the mounting housing 1. The upper and lower laser rangefinders 10 operate, and the external control mechanism calculates the thickness of the plastic tarpaulin. This method not only greatly reduces wear on the plastic tarpaulin during measurement, ensuring its quality, but also avoids measurement errors caused by unilateral laser measurement, effectively improving the accuracy of thickness measurements.

[0075] Reference Figure 1 、 Figure 2 and Figure 4 The plastic tarpaulin thickness detection device provided in the embodiment of the present application has a driving mechanism including a motor 11 and two first gears 12 .

[0076] The output end of the motor 11 is fixedly connected to one of the transmission rollers 3 ; the first gear 12 is installed on one side of the transmission roller 3 , and the two first gears 12 are meshed and connected.

[0077] After the motor 11 is running, under the connection of the two first gears 12, the two transmission rollers 3 rotate towards each other, pulling the plastic tarpaulin to one side.

[0078] Reference Figure 1 、 Figure 2 、 Figure 4 and Figure 5 In the plastic tarpaulin thickness detection device provided in an embodiment of the present application, the limiting mechanism also includes a reversing component 7, which is used to drive the two adjustment rollers 6 to rotate in the opposite direction to the transmission roller 3. The reversing component 7 includes a first driving wheel 701 and a second gear 703.

[0079] Among them, the first driving wheel 701 is fixedly installed on one of the first gears 12; the second gear 703 is installed at one end of the adjusting roller 6, and the two second gears 703 are meshed with each other. One side of one of the second gears 703 is meshed and connected with the third gear 702, and a driving shaft 706 is fixedly installed on one side of the third gear 702. The second driving wheel 705 is sleeved on the outside of the driving shaft 706, and the first transmission belt 704 is installed on one side of the second driving wheel 705. The first driving wheel 701 and the second driving wheel 705 are friction-driven with the first transmission belt 704.

[0080] During the rotation of the transmission roller 3, under the connection of the first driving wheel 701, the first transmission belt 704 and the second driving wheel 705, the third gear 702 follows the rotation. Since the third gear 702 is meshed with the second gear 703, the adjustment roller 6 will rotate in the opposite direction to the transmission roller 3, straightening the plastic tarpaulin located in the mounting shell 1, thereby effectively improving the accuracy of the thickness measurement of the plastic tarpaulin.

[0081] Based on the above scheme, the plastic tarpaulin thickness detection device provided by this application has a connecting groove 707 on the second driving wheel 705, one side of the driving shaft 706 is made of rubber material and has an anti-slip strip on the surface, and the driving shaft 706 and the connecting groove 707 are frictionally transmitted.

[0082] Since one side of the driving shaft 706 is made of rubber material and has an anti-slip strip on the surface, the second driving wheel 705 mainly relies on friction to drive the adjustment roller 6 to rotate. When the friction between the plastic tarpaulin and the adjustment roller 6 is large, the second driving wheel 705 will idle. In this way, the adjustment roller 6 can be prevented from damaging the plastic tarpaulin, which can not only ensure the straightening state of the plastic tarpaulin, but also prevent the plastic tarpaulin from being damaged by excessive tension.

[0083] Reference Figure 3 、 Figure 7 and Figure 8 In the plastic tarpaulin thickness detection device provided in the embodiment of the present application, the alignment component 5 includes a detection mechanism and a lifting mechanism. The detection mechanism includes a fixed frame 501, two movable plates 503, a pressure sensor 506 and a pushing mechanism.

[0084] Among them, the fixed frame 501 is fixedly installed on one side of the installation shell 1; the connecting frame 504 is fixedly installed on the inner side of the movable plate 503, and the contact rod 505 is slidably connected to the inner side of the connecting frame 504, and a ball 507 is embedded in the end of the contact rod 505; the pressure sensor 506 is fixedly installed on the movable plate 503, and the outer end of the contact rod 505 is abutted against the detection end of the pressure sensor 506; the pushing mechanism is used to drive the two movable plates 503 to move in a straight line; the lifting mechanism is used to drive the second support frame 14 to move up and down.

[0085] After the fabric is secured for testing, the two movable plates 503, driven by the push mechanism, move the pressure sensor 506 inward until the ball bearing 507 contacts the surface of the plastic tarpaulin. If the plastic tarpaulin deviates up or down during testing, the contact rod 505 moves outward, applying pressure to the pressure sensor 506. At this point, under the control of the external control mechanism, the lifting mechanism operates, and the second support frame 14 drives the adjustment roller 6 up and down until the plastic tarpaulin is adjusted to a horizontal position. This method allows the position of the plastic tarpaulin to be adjusted in real time, ensuring that the plastic tarpaulin remains horizontal during thickness measurement, fully ensuring the consistency and accuracy of the measurement results.

[0086] Based on the above scheme, the plastic tarpaulin thickness detection device provided by this application has a pushing mechanism including a first bidirectional screw rod 502 rotatably connected to a fixed frame 501, and a movable plate 503 is threadedly connected to the first bidirectional screw rod 502; the lifting mechanism includes a plurality of electric push rods 508, and the output end of the electric push rod 508 is connected and fixed to the second support frame 14.

[0087] The staff rotates the first bidirectional screw rod 502, and the movable plates 503 on both sides move toward each other.

[0088] Reference Figure 1 and Figure 4 In the plastic tarpaulin thickness detection device provided in the embodiment of the present application, a roller spacing adjustment mechanism is installed on the first support frame 4 and the second support frame 14. The roller spacing adjustment mechanism is used to adjust the roller spacing between the two transmission rollers 3 and the two adjustment rollers 6. The roller spacing adjustment mechanism includes a slider 15, a universal connecting rod 13 and a second bidirectional screw rod 16.

[0089] Among them, the slider 15 is slidably installed on the first support frame 4 and the second support frame 14, and the transmission roller 3 and the adjustment roller 6 are rotatably connected to the corresponding slider 15; the universal connecting rod 13 on one side is fixedly connected between the transmission roller 3 and the corresponding first gear 12, and the universal connecting rod 13 on the other side is fixedly connected between the adjustment roller 6 and the corresponding second gear 703. The setting of the universal connecting rod 13 enables the transmission roller 3 and the adjustment roller 6 to still rotate smoothly after the roller spacing is adjusted; the second bidirectional screw rod 16 is rotatably installed on the first support frame 4 and the second support frame 14, and the slider 15 is rotatably connected to the corresponding second bidirectional screw rod 16.

[0090] The staff rotates the second bidirectional screw 16, and the slider 15 drives the transmission roller 3 or the adjustment roller 6 to move linearly, so that the roller distance between the two transmission rollers 3 and the two adjustment rollers 6 can be adjusted. In this way, the technical solution can be applied to plastic tarpaulins of different thicknesses, thereby improving the applicability of the technical solution.

[0091] Reference Figure 1 、 Figure 2 、 Figure 8 and Figure 9 In the plastic tarpaulin thickness detection device provided in the embodiment of the present application, the chip removal component 8 includes an induced draft fan 807 and a dust cleaning cylinder 802.

[0092] Among them, the suction end of the induced draft fan 807 is connected to the receiving pipe 801; the dust cleaning cylinder 802 is connected to the inner cavity of the receiving pipe 801, the dust cleaning cylinder 802 is densely covered with bristles 806, and a plurality of dust suction grooves 803 are opened on the dust cleaning cylinder 802.

[0093] Before the plastic tarpaulin enters the installation shell 1 for thickness measurement, the brush bristles 806 will brush off the raw materials and dust remaining on the surface of the plastic tarpaulin. At the same time, under the action of the induced draft fan 807, these impurities will be sucked away, effectively preventing these debris from affecting the accuracy of laser thickness measurement.

[0094] Based on the above scheme, the plastic tarpaulin thickness detection device provided in this application has a dust cleaning cylinder 802 that is rotatably installed on one side of the receiving tube 801, and a third driving wheel 804 is fixedly installed on the end of the receiving tube 801 and the second gear 703. A second transmission belt 805 is installed on one side of the second gear 703, and the third driving wheel 804 and the second transmission belt 805 are frictionally transmitted.

[0095] During the rotation of the second gear 703, under the connection between the third driving wheel 804 and the second transmission belt 805, the dust cleaning cylinder 802 will drive the bristles 806 to rotate, effectively improving the cleaning effect of the plastic tarpaulin.

[0096] Reference Figure 1 、 Figure 2 、 Figure 8 and Figure 10 In the plastic tarpaulin thickness detection device provided in the embodiment of the present application, the air-increasing component 9 includes a filter box 901 , a blowing pipe 903 and a cutting air net 905 .

[0097] Among them, the filter box 901 is fixedly connected between the suction end of the induced draft fan 807 and the end of the receiving tube 801, and a sealing cover 904 is inserted on the filter box 901, and a filter membrane 902 is installed on one side of the sealing cover 904; the end of the blowing pipe 903 passes through one side of the mounting shell 1 and extends to its inner cavity; the cutting wind net 905 is installed on one side of the end of the blowing pipe 903, and the wind blown out of the blowing pipe 903 will be blocked and separated by the cutting wind net 905, effectively preventing the rapid airflow from disturbing the plastic tarpaulin and affecting the measurement accuracy.

[0098] The airflow absorbed by the induced draft fan 807 is filtered by the filter membrane 902 and then blown to the cutting air net 905 through the blowing pipe 903. After being blocked and separated, this part of the airflow flows into the installation shell 1, which makes the installation shell 1 always in a positive pressure state, thereby preventing external dust from flowing in and further improving the accuracy of laser thickness measurement.

[0099] The plastic tarpaulin thickness detection process described in this embodiment is implemented based on any plastic tarpaulin thickness detection device and includes the following steps:

[0100] S1. The staff will put the cloth roll on the support rod 17 and pass one end of the cloth through the two adjustment rollers 6, the through slot 101 and the two transmission rollers 3 in sequence;

[0101] S2. According to the thickness of the plastic tarpaulin, rotate the second bidirectional screw 16 until the roller distance is adjusted to an appropriate state;

[0102] S3. Rotate the first bidirectional screw 502. The movable plates 503 on both sides drive the corresponding contact rods 505 to move inward until the balls 507 contact the surface of the plastic tarpaulin.

[0103] S4, the motor 11 is running, the two transmission rollers 3 rotate in opposite directions, and the plastic tarpaulin is pulled out to one side;

[0104] S5, the adjustment roller 6 rotates in the opposite direction to the transmission roller 3 to straighten the plastic tarpaulin in the mounting housing 1;

[0105] S6, the dust cleaning cylinder 802 drives the bristles 806 to rotate while the induced draft fan 807 operates, and the raw materials and dust remaining on the surface of the plastic tarpaulin will be brushed off and sucked into the filter box 901;

[0106] S7, the cloth gradually enters the installation shell 1, and the laser rangefinders 10 on the upper and lower sides are in operation. After calculation by the external control mechanism, the thickness of the plastic tarpaulin can be obtained.

[0107] The implementation principle of the plastic tarpaulin thickness detection device of the embodiment of the present application is as follows: when relevant staff need to use this technical solution to detect the thickness of the plastic tarpaulin, the staff first fixes the cloth roll on the supporting rod 17, and passes one end of the cloth through the two adjustment rollers 6, the through groove 101 and the two transmission rollers 3 in sequence.

[0108] Then, the staff rotates the second bidirectional screw 16 according to the thickness of the plastic tarpaulin, and the slider 15 then drives the transmission roller 3 or the adjustment roller 6 to move linearly until the roller distance is adjusted to an appropriate state.

[0109] Subsequently, the staff rotates the first bidirectional screw 502, and the movable plates 503 on both sides drive the corresponding contact rods 505 to move inward until the balls 507 contact the surface of the plastic tarpaulin.

[0110] Under the control of the external control mechanism, the motor 11 is operated, and the two conveying rollers 3 rotate in opposite directions, pulling the plastic tarpaulin to one side.

[0111] As the cloth continues to move, under the connection of the first driving wheel 701, the first transmission belt 704 and the second driving wheel 705, the adjustment roller 6 will rotate in the opposite direction to the transmission roller 3, straightening the plastic tarpaulin located in the installation shell 1.

[0112] During the rotation of the adjustment roller 6, the dust cleaning cylinder 802 will drive the brush 806 to rotate. At this time, the induced draft fan 807 will run synchronously, and the raw materials and dust remaining on the surface of the plastic tarpaulin will be brushed off and sucked into the filter box 901.

[0113] The air flow absorbed by the induced draft fan 807 is filtered by the filter membrane 902 and blown to the cutting air net 905 through the blowing pipe 903. After being blocked and separated, this part of the air flow flows into the installation shell 1, which makes the installation shell 1 always in a positive pressure state.

[0114] Subsequently, the cloth gradually enters the installation shell 1, and the laser rangefinders 10 on the upper and lower sides are operated. After calculation by the external control mechanism, the thickness of the plastic tarpaulin can be obtained.
