Description

Technical Field

[0001] This utility model relates to the field of label machine technology, specifically to a mechanism that can identify the width of paper. Background Technology

[0002] A label printer is a device that can print various types of labels. Through built-in printing technologies such as thermal printing and thermal transfer printing, it clearly prints information such as text, patterns, and barcodes onto label materials. It is suitable for various scenarios such as office, logistics, retail, warehousing, and medical. It can help users efficiently complete tasks such as item classification, labeling, price marking, and asset management. It features easy operation, clear printing, and durable labels.

[0003] Accurate paper size recognition is a key factor in ensuring automated operation and efficient work of equipment. The traditional method involves manually measuring the paper size with tools and then manually inputting or selecting the paper width to set the size. The entire operation is cumbersome and reduces overall work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a mechanism for recognizing paper width dimensions, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows.

[0006] A paper width recognition mechanism includes a lower frame with a horizontal plate installed inside. Two paper clamping blocks are symmetrically mounted on the upper surface of the horizontal plate via a transmission mechanism, which enables the two paper clamping blocks to move simultaneously in opposite directions. A sliding rheostat is mounted on the lower surface of the horizontal plate, with the end of the upper slider of the rheostat connected to the bottom of one of the paper clamping blocks. A centering sensor is located on the outer side of the horizontal plate.

[0007] As can be seen, by setting up a transmission mechanism, the two paper clamping blocks can move synchronously and clamp the two sides of the paper width respectively. The paper clamping blocks drive the slider to slide on the surface of the sliding rheostat. The paper width can be obtained by the resistance value, thus identifying the overall width of the paper. Compared with the traditional method, the size identification can be completed at the same time as clamping the paper, avoiding cumbersome operation steps and improving the overall work efficiency.

[0008] Furthermore, the transmission mechanism includes an upper sealing plate mounted on the upper side of the horizontal plate, a fixed column mounted on the bottom of the upper sealing plate, a transmission gear sleeved on the outer surface of the fixed column, two parallel racks slidably mounted on the upper surface of the horizontal plate, both racks meshing with the transmission gear, and two paper clamping blocks respectively mounted on the upper surface of the two racks.

[0009] Furthermore, the surface of the horizontal plate is provided with a groove, and the transmission gear is disposed within the groove. A protrusion is installed inside the groove, and a bevel gear is installed at the bottom of the transmission gear, with the protrusion positioned between the teeth of the bevel gear. A spring is fitted onto the outer surface of the fixing column, with both ends of the spring abutting against the upper sealing plate and the bevel gear, respectively.

[0010] Furthermore, a through groove is formed on the surface of the lower middle frame, and a U-shaped strip is installed at the bottom of the centrally located sensor, with the bottom of the U-shaped strip extending through the through groove to the lower side of the lower middle frame. A through hole is formed in the middle of the U-shaped strip, and a positioning post is set inside the through hole. Arc-shaped posts are set on both sides of the lower middle frame in the width direction of the through groove.

[0011] Furthermore, the surface of the U-shaped strip has a notch that extends into the interior of the through hole.

[0012] Furthermore, the upper surface of the centered sensor is provided with anti-slip protrusions.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0014] 1. This utility model, through the setting of the transmission mechanism, enables two paper clamping blocks to move synchronously and clamp on both sides of the paper width direction respectively. The paper clamping blocks drive the slider to slide on the surface of the sliding rheostat. The paper width can be obtained by the resistance value, thereby identifying the overall width of the paper. Compared with the traditional method, the size identification can be completed at the same time as clamping the paper, avoiding cumbersome operation steps and improving the overall work efficiency.

[0015] 2. This utility model, through the setting of positioning columns and arc-shaped columns, can adjust the horizontal position of the centering sensor, thereby adjusting the printing position on the paper, which can meet different usage needs, and has a simple structure and is easy to use.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-8 As shown, a paper width recognition mechanism includes a lower frame 1. A horizontal plate 101 is installed inside the lower frame 1. Two paper clamping blocks 102 are symmetrically mounted on the upper surface of the horizontal plate 101 via a transmission mechanism 2. The transmission mechanism 2 enables the two paper clamping blocks 102 to move simultaneously in opposite directions. A sliding rheostat 103 is installed on the lower surface of the horizontal plate 101. The end of the upper slider 104 of the sliding rheostat 103 is connected to the bottom of one of the paper clamping blocks 102. A centering sensor 105 is provided on the outer side of the horizontal plate 101.

[0027] In use, the paper is placed between two paper clamping blocks 102, and then one of the paper clamping blocks 102 is slid. Under the action of the transmission mechanism 2, the two paper clamping blocks 102 clamp the two sides of the paper width direction respectively. At this time, the two paper clamping blocks 102 limit the paper and ensure the stability of the paper conveying. When the paper clamping block 102 is slid, it drives the slider 104 to slide on the surface of the sliding rheostat 103. The size of half the paper width can be obtained by the resistance value, so that the overall width of the paper can be identified. Compared with the traditional method, the size identification can be completed at the same time as clamping the paper, avoiding cumbersome operation steps and improving the overall work efficiency.

[0028] The centering sensor 105 is used to identify the center position of the paper, so that information such as text and patterns can be printed on the paper with the centering sensor 105 as the center.

[0029] It is worth noting that both the sliding rheostat 103 and the centering sensor 105 are electrically connected to the controller of the label printer body. The controller performs unified control and parameter adjustment, which is a common existing technology, so it will not be described in detail here.

[0030] Preferably, the transmission mechanism 2 includes an upper sealing plate 201 installed on the upper side of the horizontal plate 101, a fixing post 202 installed at the bottom of the upper sealing plate 201, a transmission gear 203 sleeved on the outer surface of the fixing post 202, two parallel racks 204 slidably installed on the upper surface of the horizontal plate 101, and both racks 204 are meshed with the transmission gear 203, and two paper clamping blocks 102 are respectively installed on the upper surface of the two racks 204.

[0031] The transmission gear 203 can rotate on the outside of the fixed column 202. When one of the paper clamping blocks 102 slides, the paper clamping block 102 drives the rack 204 connected to it to slide horizontally. Through the meshing relationship between the rack 204 and the transmission gear 203, the other rack 204 can be driven to move synchronously in the opposite direction, so as to achieve the purpose of driving the two paper clamping blocks 102 to move inward or outward at the same time.

[0032] Preferably, the surface of the horizontal plate 101 is provided with a groove 3, and the transmission gear 203 is disposed in the groove 3. A protrusion 301 is installed inside the groove 3, and a bevel gear 302 is installed at the bottom of the transmission gear 203, with the protrusion 301 positioned between the teeth of the bevel gear 302. A spring 303 is sleeved on the outer surface of the fixing post 202, and both ends of the spring 303 abut against the upper sealing plate 201 and the bevel gear 302, respectively.

[0033] Under the elastic force of the spring 303, the bevel gear 302 can abut against the protrusion 301, which at this time limits the angle of the transmission gear 203, thus limiting the position of the two paper clamping blocks 102. When it is necessary to adjust the position of the paper clamping block 102, it is only necessary to slide it with a little force to drive the bevel gear 302 to rotate up and down above the protrusion 301, so as to achieve the purpose of transmission. After the paper clamping block 102 is released, the limiting effect on it can be restored.

[0034] Preferably, a through groove 4 is formed on the surface of the lower middle frame 1, and a U-shaped strip 401 is installed at the bottom of the centrally located sensor 105, with the bottom of the U-shaped strip 401 extending through the through groove 4 to the lower side of the lower middle frame 1. A through hole 402 is formed in the middle of the U-shaped strip 401, and a positioning post 403 is provided inside the through hole 402. Arc-shaped posts 404 are provided on both sides of the lower middle frame 1 in the width direction of the through groove 4.

[0035] When the content to be printed does not need to be centered, the centering sensor 105 can be slid horizontally. The centering sensor 105, through the U-shaped strip 401, drives the positioning post 403 to move on the surface of the arc-shaped post 404. Under the elastic deformation of the U-shaped strip 401, the positioning post 403 can always be pulled to abut against the arc-shaped post 404. Therefore, when the centering sensor 105 is slid to the designated position, the positioning post 403 is locked in the gap between two adjacent arc-shaped posts 404, thus achieving the function of limiting its position. Since the text, pattern, and other information content is printed on the paper with the centering sensor 105 as the center, the printing position on the paper can be changed by adjusting the position of the centering sensor 105.

[0036] Preferably, the surface of the U-shaped strip 401 is provided with a notch 5, which extends into the interior of the through hole 402.

[0037] By setting the notch 5, the deformation capability of the U-shaped strip 401 is improved, allowing the centering sensor 105 to slide more easily and smoothly to change its position.

[0038] Preferably, the upper surface of the centered sensor 105 is provided with anti-slip protrusions 6.

[0039] The anti-slip protrusions 6 increase the surface friction, effectively reducing the risk of slippage when sliding the centering sensor 105.

[0040] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

For those skilled in the art, any equivalent substitutions or obvious modifications made without departing from the concept of the present invention, and which have the same performance or use, should be considered as falling within the patent protection scope defined by the submitted claims.
