Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of thickness measuring instruments, and more specifically, to a thickness measuring instrument for household paper. Background Technology

[0002] Household paper refers to various types of sanitary wipes used for personal hygiene at home and when out and about. This includes toilet paper rolls, facial tissues, boxed tissues, pocket tissues, paper handkerchiefs, napkins, hand towels, wet wipes, and kitchen paper towels. Household paper is primarily used for daily hygiene, hence the common term "household paper" used in the paper industry. It is an indispensable type of paper in people's lives. It comes in various shapes, including single square sheets (called facial tissues) and rolled into rolls (called toilet paper rolls). Thickness testing is used to measure the thickness of household paper. A thickness measuring instrument is a specialized instrument for measuring the thickness of objects. It can accurately measure the thickness of various materials, such as metals, plastics, paper, and fabrics. The measurement range of this instrument varies depending on its type and intended use, ranging from extremely small thicknesses (such as micron-level film thickness) to the thickness of larger objects. Its working principle involves a measuring probe contacting the surface of the object being measured, using a mechanical transmission device to convert the change in thickness into a measurable displacement signal, and then using a sensor to convert the displacement signal into an electrical signal for processing and display.

[0003] In existing technology, thickness measuring instruments for household paper typically place the paper directly on the measuring instrument to measure its thickness. However, the paper is easily displaced by external forces during the measurement process, which may affect the measurement results and lead to deviations in the measurement data. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this disclosure provide a thickness measuring instrument for household paper, which solves the technical problem in the prior art that paper is easily affected by external forces during the measurement process and may be displaced, which may affect the measurement effect and cause deviations in the measurement data.

The first guide roller is rotatably mounted inside the frame. The second guide roller is rotatably mounted inside the frame via two movable plates and is positioned above the first guide roller. The movable plates are capable of vertical movement inside the frame. The movable plates are square in shape and can move within the cavity formed inside the frame. The second guide roller moves synchronously with the movable plates. The positioning mechanism is mounted on one of the movable plates on one side and moves synchronously with the movable plates. The positioning mechanism is used to position the second guide roller inside the frame.

[0009] As a preferred embodiment of the thickness measuring instrument for household paper described in this utility model, in order to increase the friction between the abutting positioning plate and the anti-slip strip, an anti-slip pad is provided on the side of the abutting positioning plate near the anti-slip strip, and the anti-slip pad abuts against the anti-slip strip under the action of the abutting positioning plate.

[0010] As a preferred embodiment of the thickness measuring instrument for household paper described in this utility model, in order to realize the winding of the paper and the adjustment of the winding height of the winding roller, the main body of the measuring instrument is equipped with a U-shaped seat through an L-shaped plate. Two upright plates are provided on the upper side of the U-shaped seat through a connecting mechanism. The connecting mechanism is used to connect the U-shaped seat and the upright plates.

[0011] The connecting mechanism includes a connecting seat, a connecting plate, a sliding plate, and a slide rail. The connecting seat is installed on the inner bottom wall of the U-shaped seat. The connecting plate is installed on the lower side of the upright plate and moves synchronously with the upright plate. The sliding plate is installed on the lower side of the connecting plate and moves synchronously with the connecting plate. The sliding plate is sleeved on the outer side of the connecting seat.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1-5 As shown, this invention discloses a thickness measuring instrument for household paper according to an embodiment of the present invention. The instrument includes a main body 1, a frame 2, a first guide roller 3, a second guide roller 4, a moving plate 5, and a positioning mechanism. In contrast to existing technologies where paper is easily displaced by external forces during measurement, potentially affecting measurement results and causing data deviations, this embodiment addresses this issue by using the first guide roller 3 and the second guide roller 4 in conjunction to guide and limit the paper, ensuring stability during thickness measurement, reducing the probability of paper displacement, and guaranteeing accurate thickness measurement data. The moving plate 5 and the positioning mechanism work together to adjust the height and position of the second guide roller 4, allowing operators to adjust its height according to different paper thicknesses. This enables the device to measure paper of varying thicknesses, increasing its applicability.

[0032] The main body of the detector 1 contacts the surface of the paper through a precision probe, and then uses a mechanical transmission mechanism to convert the displacement of the probe into a measurable signal, thereby realizing the detection of the paper thickness.

[0033] like Figure 1 and Figure 2 As shown, frame 2 is mounted on one side of the main body 1 of the detector via a mounting plate. First guide roller 3 is rotatably mounted inside frame 2. Second guide roller 4 is mounted inside frame 2 via a positioning mechanism and is positioned above first guide roller 3. A movable opening is provided on the inner side of frame 2, the width of which is adapted to the diameter of second guide roller 4. When second guide roller 4 moves with movable plate 5, it moves within the movable opening. Figure 3 As shown, the positioning mechanism includes a cylinder 101, an adjusting frame 102, a spring 103, and an abutting positioning plate 104. Two anti-slip strips 9 are provided on one side of the frame 2, and the two anti-slip strips 9 are symmetrically arranged on the frame 2. The anti-slip strips 9 are located between the frame 2 and the abutting positioning plate 104. An anti-slip pad is provided on the side of the abutting positioning plate 104 near the anti-slip strips 9. The anti-slip pad abuts against the anti-slip strips 9 under the action of the abutting positioning plate 104. The anti-slip strips 9 and the anti-slip pad can increase the friction between the frame 2 and the abutting positioning plate 104, thereby ensuring the positioning effect after the abutting positioning plate 104 abuts. The first guide roller 3 and the second guide roller 4 can guide and limit the paper, thereby ensuring the stability of the paper during the detection process. The operator can adjust the height of the second guide roller 4 through the moving plate 5, so that the first guide roller 3 and the second guide roller 4 can limit the paper of different thicknesses. The positioning mechanism can position the second guide roller 4, thereby ensuring the stability of the second guide roller 4 after adjustment.

[0034] like Figure 1 and Figure 4 As shown, the main body 1 of the detector is equipped with a U-shaped seat 6 via an L-shaped plate. Two upright plates 7 are connected to the upper side of the U-shaped seat 6 via a connecting mechanism. A take-up roller 8 is rotatably mounted on the inner side of each upright plate 7. One of the upright plates 7 on one side is equipped with a drive mechanism for rotating the take-up roller 8. The drive mechanism is a forward and reverse rotating motor. Figure 5 As shown, the connecting mechanism includes a connecting seat 201, a connecting plate 202, a sliding plate 203, and a slide rail 204. Multiple elastic protrusions 10 are provided on the outer side of the connecting seat 201. The multiple elastic protrusions 10 are vertically arranged on the outer side of the connecting seat 201. The elastic protrusions 10 can limit the position of the sliding plate 203 on the connecting seat 201, thereby ensuring the stability of the sliding plate 203 on the connecting seat 201. The winding roller 8 can wind up the paper, thereby keeping the paper stable when it passes through the detector body 1.

[0035] Working principle:

[0036] The staff adjusts the height of the second guide roller 4 according to the different thicknesses of the paper. The staff pulls the adjustment frame 102 to move it. During the movement of the adjustment frame 102, the spring 103 is compressed. The adjustment frame 102 drives the abutment positioning plate 104 to move and cancel the abutment of the abutment positioning plate 104. Then, the staff adjusts the position of the moving plate 5 inside the frame 2. The moving plate 5 drives the second guide roller 4 to rise and fall, realizing the adjustment of the height of the second guide roller 4. After the adjustment is completed, the staff releases the adjustment frame 102. Under the action of the spring 103, the adjustment frame 102 drives the abutment positioning plate 104 to abut against the anti-slip strip 9, realizing the positioning of the second guide roller 4 after the height adjustment.

[0037] Then, the staff passes the paper to be tested between the first guide roller 3 and the second guide roller 4 and then puts it onto the take-up roller 8. After being put on, the forward and reverse motor is started, which drives the take-up roller 8 to rotate. The take-up roller 8 winds up the paper. During the winding process, the first guide roller 3 and the second guide roller 4 guide and limit the paper. The probe inside the main body 1 of the detector comes into contact with the surface of the paper. The probe moves laterally through the mechanical transmission mechanism. During the movement, the probe detects the thickness of the paper.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
