Description

Technical Field

[0001] This utility model relates to the field of label production, specifically to a label conveying and positioning device. Background Technology

[0002] After the labels are printed, they need to be conveyed to an inspection platform. The inspection platform is equipped with instruments to inspect the labels. As the labels pass through the inspection platform, the instruments inspect the printed patterns on the labels to determine whether the printing quality of the labels is up to standard.

[0003] The testing platform is equipped with two positioning blocks, which are located at the two edges of the label paper. The label paper is conveyed on the testing platform, and the two positioning blocks limit the movement of the label paper to prevent it from shifting during the conveyance.

[0004] However, with the positioning block fixed in place, the label paper moves, causing friction between the edge of the label paper and the positioning block. This friction is of the sliding friction type, which results in burrs on the edge of the label paper, making the edge of the label paper rough and affecting the quality of the label paper. It also produces some friction noise. Utility Model Content

[0005] The present invention aims to provide a label conveying and positioning device to solve the problem of relative friction between the edge of the label paper and the positioning block during the conveying process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a label conveying and positioning device, comprising a detection platform and two positioning units, each positioning unit comprising a positioning block, the two positioning blocks being slidably connected relative to each other on the detection platform, each positioning block being rotatably connected to a rotating shaft, the rotating shafts on the two positioning blocks being arranged opposite to each other, and both rotating shafts being arranged vertically; each rotating shaft having an annular groove on its circumferential side, the lower inner wall of the annular groove being lower than the surface of the detection platform, and the upper inner wall of the annular groove being higher than the surface of the detection platform.

[0007] The principle and advantages of this solution are as follows: Two positioning units are used to limit the movement of the label paper, preventing deviation during label paper transport. The label paper is transported between the two positioning units on the detection platform. The edge of the label paper is located in an annular groove, and the inner wall of the annular groove abuts against the edge of the label paper, thus limiting the transport of the label paper and preventing deviation. During the transport process, the rotating shaft can rotate under the influence of the label paper, or the rotating shaft can be additionally driven to rotate. Because the rotating shaft is in a rotating state, the contact points between the label paper and the rotating shaft, as well as the edge of the label paper, all move, and the two are essentially in a relatively stationary state. This reduces the relative friction between the label paper and the rotating shaft, resulting in less friction on the edge of the label paper, reducing the likelihood of burrs, and improving the quality of the label paper.

[0008] Meanwhile, since the annular groove is arc-shaped, the edge of the label paper contacts the inner wall of the annular groove at a point, rather than a line, compared to existing technologies. This reduces the degree of contact between the label paper and the positioning unit. From this perspective, it also helps to reduce the friction between the edge of the label paper and the rotating shaft. The edge of the label paper experiences less friction, making it less prone to burrs and improving the quality of the label paper.

[0009] To achieve the above objectives, the present invention may also adopt the following technical solution: a label conveying and positioning device, comprising a detection platform and two positioning units, each positioning unit comprising a positioning block, the two positioning blocks being opposite to each other and slidably connected to the detection platform; each of the two positioning blocks having a contact portion on its opposite side, the two contact portions being oppositely arranged, the contact portion being a vertical edge, the thickness of the vertical edge being less than 1mm.

[0010] The principle and advantages of this solution are as follows: Two positioning units are used to limit the movement of the label paper, preventing it from shifting during transport. The label paper is transported between the two positioning units on the detection platform. The edge of the label paper contacts the contact part, and the contact part abuts against the edge of the label paper, thus limiting the transport of the label paper and preventing it from shifting. During transport, since the contact part is a vertical edge with a thickness of less than 1mm, it can be considered as a vertical line. The contact between the edge of the label paper and the contact part is a point contact, rather than a line contact, compared to existing technologies. This reduces the degree of contact between the label paper and the positioning unit, which helps to reduce friction between the edge of the label paper and the contact part. Less friction on the edge of the label paper reduces the likelihood of burrs and improves the quality of the label paper.

[0011] The following are further improvement plans. If the multiple improvement plans do not contradict each other, they can be combined arbitrarily.

[0012] Preferably, as an improvement, the positioning block is equipped with a motor for driving the rotating shaft. Thus, the motor drives the rotating shaft to rotate, and the rotational power of the shaft comes from the motor rather than from the label paper. This helps reduce friction between the label paper and the rotating shaft, resulting in less friction on the edges of the label paper, reducing the likelihood of burrs, and improving the quality of the label paper.

[0013] Preferably, as an improvement, the diameter of the rotating shaft is 0.5-1cm.

[0014] Preferably, as an improvement, the two positioning blocks have shaft grooves on their opposite sides, and the rotating shaft rotates at the shaft grooves, with the circumferential side of the rotating shaft protruding from the shaft grooves. The shaft grooves are used to accommodate the rotating shaft, making the structure of the rotating shaft and positioning blocks compact and reasonable, and the rotating shaft will not occupy too much space on the outside of the positioning blocks.

[0015] Preferably, as an improvement, the detection platform is provided with a first strip hole, and both positioning blocks pass downward through the first strip hole. The bottom of the positioning block is provided with an extension located below the bottom of the rotating shaft, and the bottom of the rotating shaft is rotatably connected to the extension.

[0016] Therefore, the first slotted hole serves as a guide for adjusting the sliding position of the positioning block. The extension is located below the bottom of the rotating shaft, and it provides support for the installation and rotation of the rotating shaft.

[0017] Preferably, as an improvement, the bottom of the testing platform is fixedly connected to a fixed plate, and each of the two positioning units also includes a sliding block, with both sliding blocks slidably connected to the fixed plate; tightening bolts are connected between the two positioning blocks and the sliding blocks below them, and a rotating head for rotating the tightening bolts is provided above each positioning block; and a pressing surface for pressing the testing platform is provided on each of the two positioning blocks.

[0018] Therefore, by rotating the rotating head, the rotating head drives the tightening bolt to rotate. When the tightening bolt is tightened, the positioning block and the sliding block are tightened, and the pressing surface of the positioning block presses the detection platform, thereby locking the positioning block on the detection platform. The positioning block will not slide on the detection platform to adjust its position. When the tightening bolt is loosened, the positioning block and the sliding block are not tightened, and the pressing surface of the positioning block will not press the detection platform. The positioning block can slide on the detection platform to adjust its position.

[0019] Preferably, as an improvement, a clamping platform is fixedly provided below the rotating head, and the bottom of the clamping platform abuts against the top of the positioning block.

[0020] Therefore, by rotating the rotating head, the rotating head drives the tightening bolt to tighten the positioning block and sliding block. The tightening bolt moves downward as a whole, pressing down on the top of the positioning block from the bottom of the pressing platform, thus pressing the pressing surface of the positioning block against the testing platform. By rotating the rotating head in the opposite direction, the rotating head loosens the tightening bolt, and the tightening bolt moves upward as a whole. The bottom of the pressing platform no longer presses down on the top of the positioning block, and the positioning block no longer presses against the testing platform, allowing it to slide on the testing platform.

[0021] Preferably, as an improvement, the fixing plate is provided with a second strip hole, the first strip hole and the second strip hole are opposite each other, and both sliding blocks pass through the second strip hole.

[0022] Therefore, by setting a second strip hole on the fixed plate, the sliding block is guided.

[0023] Preferably, as an improvement, both ends of the fixing plate are bent upwards, and both ends of the fixing plate are fixedly connected to the detection platform.

[0024] Therefore, the end of the fixing plate is bent to facilitate the connection between the end of the fixing plate and the detection platform.

[0025] Preferably, as an improvement, each sliding block is provided with a groove, and the edge of the second strip hole is located in the groove.

[0026] Therefore, the edge of the second strip hole is engaged in the groove, and the sliding block can slide on the fixed plate, but the sliding block will not move vertically. This makes it easier to tighten the positioning block and the sliding block, and at the same time makes the sliding block slide more stably on the fixed plate. Attached Figure Description

[0034] Example 1 The basics are as follows: Figures 1-5 The label conveying and positioning device shown includes a frame (not shown), a detection platform 1, and two positioning units. The detection platform 1 is plate-shaped, with a length of 0.5-1m and a thickness of 0.5cm. The detection platform 1 has a first strip-shaped hole 2 along its length. The detection platform 1 can be fixed to the frame with screws.

[0035] Both positioning units include positioning blocks 3 and sliding blocks 10. The two positioning blocks 3 are slidably connected to the detection platform 1 and pass downward through the first strip hole 2. Specifically, each positioning block 3 has a first sliding part 13 integrally provided on its bottom, which passes downward through the first strip hole 2. The bottom of the positioning block 3 is provided with a pressing surface 18, which is in contact with the top surface of the detection platform 1 and can press the top surface of the detection platform 1.

[0036] A fixing plate 9 is fixedly connected to the bottom of the detection platform 1. Specifically, in this embodiment, both ends of the fixing plate 9 are bent upwards, and both ends of the fixing plate 9 are welded or fixed to the bottom of the detection platform 1 by screws. The fixing plate 9 has a second strip-shaped hole 19, which is parallel to and vertically opposite to the first strip-shaped hole 2. Two sliding blocks 10 are slidably connected to the fixing plate 9. Specifically, the sliding blocks 10 have grooves 14 on both sides, and the part between the grooves 14 on both sides of the sliding block 10 is the second sliding part 12. The sliding block 10 is located on the fixing plate 9, and the second sliding part 12 passes through the second strip-shaped hole 19. The edge of the second strip-shaped hole 19 is located in the groove 14, allowing the sliding block 10 to slide on the fixing plate. The bottom of the sliding block 10 is a locking plate part 11, which is locked under the fixing plate 9, so that the sliding block 10 will not move upwards and fall off the fixing plate 9, and the sliding block 10 can slide stably on the fixing plate 9. In this embodiment, the distance between the inner walls on both sides of the chute 14 is equal to the thickness of the fixing plate 9.

[0037] In this embodiment, vertical tightening bolts 16 are connected between the two positioning blocks 3 and the sliding block 10 below them. The threaded section of the tightening bolt 16 is vertically inserted into the top of the sliding block 10 and threadedly connected to the top threaded hole of the sliding block 10. The smooth section of the tightening bolt 16 passes through the positioning block 3. A clamping platform 15 is coaxially and integrally fixed to the top of the smooth section of the tightening bolt 16. The diameter of the clamping platform 15 is larger than the diameter of the smooth section, and the bottom of the clamping platform 15 can abut against the top of the positioning block 3. A rotating head 4 is coaxially and integrally fixed to the top of the clamping platform 15. By rotating the rotating head 4, the tightening bolt 16 can be rotated.

[0038] In this embodiment, both positioning units also include a rotating shaft 6. Shaft grooves 20 are provided on the opposite sides of the two positioning blocks 3. The rotating shaft 6 rotates vertically in the shaft grooves 20. Specifically, the top of the rotating shaft 6 is rotatably connected to the top of the positioning block 3 via a shaft. The first sliding part 13 is integrally provided with an extension 17, which extends below the bottom of the rotating shaft 6. The bottom of the rotating shaft 6 is rotatably mounted on the extension 17 via a shaft, and the extension 17 is used to support the rotating shaft 6. The circumferential side of the rotating shaft 6 protrudes from the shaft groove 20. In this embodiment, the diameter of the rotating shaft 6 is 0.5-1 cm. A motor 5 for driving the rotating shaft 6 to rotate is mounted (e.g., fixed by bolts) on the top of the positioning block 3. The motor 5 and the rotating shaft 6 are coaxially connected. In this embodiment, both rotating shafts 6 have annular grooves 8 on their circumferential sides. The lower inner wall of the annular groove 8 is lower than the surface of the detection platform 1. Specifically, the lower inner wall of the annular groove 8 is located in the first strip hole 2 and is lower than the upper surface of the detection platform 1. The upper inner wall of the annular groove 8 is located above the first strip hole 2. Therefore, the upper inner wall of the annular groove 8 is higher than the upper surface of the detection platform 1.

[0039] In this embodiment, the distance between the upper and lower inner walls of the annular groove 8 can be 1-5 mm. When the label paper 7 is conveyed on the detection platform 1, the label paper 7 is located between the two positioning blocks 3, and the edge of the label paper 7 is located in the annular groove 8. The label paper 7 is conveyed along the perpendicular direction of the line connecting the two positioning blocks 3. During the conveying process, the edge of the label paper 7 moves in the annular groove 8.

[0040] The specific implementation process is as follows: Normally, the tightening bolt 16 is always located on the positioning block 3 and the sliding block 10. By rotating the rotating head 4, the rotating head 4 drives the tightening bolt 16 to rotate. When the tightening bolt 16 is tightened, the tightening bolt 16 moves downward as a whole and screws into the sliding block 10. The positioning block 3 and the sliding block 10 are tightened. The pressing platform 15 below the rotating head 4 presses down against the positioning block 3. The pressing surface 18 of the positioning block 3 presses the detection platform 1, thereby locking the positioning block 3 on the detection platform 1 and preventing the positioning block 3 from sliding on the detection platform 1.

[0041] When the position of the positioning block 3 needs to be adjusted, the rotating heads 4 on the two positioning blocks 3 are rotated in opposite directions. The rotating heads 4 drive the tightening bolts 16 to rotate in opposite directions, loosening the tightening bolts 16. The tightening bolts 16 move upward as a whole and rotate upward a distance from the sliding block 10. The pressing platform 15 moves upward and no longer presses the positioning block 3 against the platform. The pressing surface 18 of the positioning block 3 will not press the detection platform 1 against the platform. The positioning block 3 can slide on the detection platform 1 to adjust its position.

[0042] After the tightening bolts 16 on the two positioning blocks 3 are loosened, the worker slides the positioning blocks 3. The positioning blocks 3 drive the sliding blocks 10 below them to slide in the second strip hole 19 of the fixing plate 9, thereby realizing the adjustment of the distance between the two positioning blocks 34 and enabling the limiting of label paper 7 of different widths.

[0043] When the positioning block 3 is in the locked state, the lower inner wall of the annular groove 8 is lower than the upper surface of the detection platform 1, and the upper inner wall of the annular groove 8 is higher than the upper surface of the detection platform 1. The label paper 7 is conveyed between the two positioning units on the detection platform 1. The edge of the label paper 7 is located in the annular groove 8, and the inner wall of the annular groove 8 abuts against the edge of the label paper 7, thereby limiting the conveyance of the label paper 7 and preventing deviation during conveyance. During the conveyance of the label paper 7, the rotating shafts 6 on the two positioning blocks 3 rotate under the drive of the motor 5. In this embodiment... Figure 1 As the label 7 is conveyed downwards, the left-side rotating shaft 6 rotates clockwise, and the right-side rotating shaft 6 rotates counterclockwise. The linear rotational speed of the rotating shaft 6 is basically the same as the moving speed of the label 7. Because the rotating shaft 6 is rotating, the contact points between the label 7 and the rotating shaft 6, as well as the edge of the label 7, all move, keeping them essentially in a relatively stationary state. This reduces the relative friction between the label 7 and the rotating shaft 6, minimizing friction on the edge of the label 7 and reducing the likelihood of burrs, thus improving the quality of the label 7. Furthermore, because the surface of the annular groove 8 is arc-shaped, the contact point 21 between the annular groove 8 and the edge of the label 7 is a point contact rather than a line contact, resulting in a small degree of contact and further reducing friction on the edge of the label 7.

[0044] Of course, in other embodiments, the rotation of the rotating shaft 6 can be driven by the motor 5 instead of the rotating shaft 6. The rotating shaft 6 is in a state of free rotation on the positioning block 3. In this way, when the label paper 7 is conveyed by the two rotating shafts 6, the edge of the label paper 7 drives the rotating shaft 6 to rotate, so that the rotating shaft 6 can also rotate. The friction between the label paper 7 and the rotating shaft 6 is small, and it is not easy to produce burrs, thus improving the quality of the label paper 7.

[0045] Example 2 The difference between this embodiment and Embodiment 1 is that the positioning block 3 in this embodiment does not have structures such as the rotating shaft 6, motor 5, and shaft groove 20. Instead, it is combined with... Figure 6 As shown, each of the two positioning blocks 3 has an integrally formed contact portion 21 on its opposite side. The contact portions 21 on the two positioning blocks 3 are arranged opposite each other. The contact portion 21 is a vertical edge, and the thickness of the vertical edge is less than 1mm.

[0046] Similar to Embodiment 1, in this embodiment, the contact portions 21 of the two positioning blocks 3 are used to limit the label paper 7, preventing the label paper 7 from shifting during transport. The label paper 7 is transported between the two positioning units on the detection platform 1. The edge of the label paper 7 contacts the contact portion 21, and the contact portion 21 abuts against the edge of the label paper 7, thereby limiting the transport of the label paper 7 and preventing it from shifting. During the transport process, since the contact portion 21 is a vertical edge with a thickness of less than 1mm, the contact portion 21 can be considered as a vertical line. The contact between the edge of the label paper 7 and the contact portion 21 is a point contact, which, compared to the prior art, is not a line contact. This reduces the degree of contact between the label paper 7 and the positioning unit, which helps to reduce the friction between the edge of the label paper 7 and the contact portion 21. The edge of the label paper 7 experiences less friction, making it less prone to burrs and improving the quality of the label paper 7.
