Description

Technical Field

[0001] This utility model relates to the field of label cutting technology, specifically a rapid cutting and positioning device for labels. Background Technology

[0002] Self-adhesive labels are a type of composite material made of paper, film, or other special materials as the face stock, coated with adhesive on the back, and with silicone-coated release paper as the backing paper. Label cutting equipment is required during the production of self-adhesive labels.

[0003] Currently, some label cutting devices have unreasonable traction mechanism designs, resulting in uneven traction force. This can easily cause labels to slip or wrinkle during transport. Furthermore, the lack of effective limiting measures during traction makes it easy for labels to deviate from the predetermined transport path, affecting subsequent cutting processes and leading to low production efficiency. For example, some devices using a single traction roller have poor traction performance when the label material is thin or has a smooth surface, making it impossible to stably transport the label to the cutting position. Therefore, we need to propose a rapid cutting and positioning device for labels. Utility Model Content

[0004] The purpose of this invention is to provide a rapid cutting and positioning device for labels, which uses a traction and limiting mechanism to traction and assist in limiting the label before and after cutting, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A label quick-cutting and positioning device, comprising: Base; Two sets of guide frames are symmetrically fixedly installed on the surfaces at both ends of the base. Inside, two sets of guide rollers with different heights are rotatably installed to guide the labels. The positioning and cutting mechanism is installed at the top center of the base and is used to position and cut the label. The traction and limiting mechanism, installed on the base, is used for traction and auxiliary limiting of the label before and after cutting; The traction limiting mechanism includes two sets of mounting brackets; Two sets of mounting frames are symmetrically fixedly installed on the top of the base, located on both sides of the positioning and cutting mechanism. The lower traction rollers are rotatably installed inside the mounting frames via bearings. One end of each traction roller passes through the mounting frame and is fixedly connected to a synchronous pulley. The two sets of synchronous pulleys are connected by a synchronous belt drive. The other end of one set of traction rollers passes through the mounting frame and is fixedly connected to a traction motor. A limit roller is rotatably installed above the traction roller. The traction roller and the limit roller work together to pull and assist in limiting the label.

[0006] Preferably, the positioning and cutting mechanism includes a support platform; The support platform is fixedly installed at the top center of the base, and a cutting groove is opened on the surface. A fixing frame is fixedly installed at the top, and a cylinder is fixedly installed at the top of the fixing frame. The bottom of the cylinder's telescopic end passes through the fixing frame and is fixedly connected to a mounting plate. A cutting die is fixedly installed at the bottom center of the mounting plate. The cutting die is adapted to the cutting groove, and a U-shaped positioning plate is movably installed on the mounting plate below the outer wall of the cutting die. This plate is used to press and position the label before cutting to prevent the label from shifting during the cutting process.

[0007] Preferably, six sets of first telescopic rods are symmetrically fixedly installed on the bottom of the mounting plate in pairs, the bottom of each of the six sets of first telescopic rods is fixedly connected to the top of the U-shaped positioning plate, and the outer wall of the first telescopic rod is fitted with a first spring.

[0008] Preferably, the fixing bracket has guide rods slidably inserted on both sides of the cylinder, and the bottom of the guide rods is fixedly connected to the top of the mounting plate.

[0009] Preferably, auxiliary rollers are rotatably mounted on both sides of the support platform via brackets, and the top of the auxiliary rollers is flush with the top of the support platform to assist in conveying labels.

[0010] Preferably, three sets of second springs are fixedly installed at equal intervals on the inner top of the mounting frame, and a concave frame is fixedly installed at the bottom of the three sets of second springs.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of a traction limiting mechanism, adopts two sets of mounting frames, with lower traction rollers installed inside. The synchronous rotation of the two sets of traction rollers is achieved through synchronous pulleys and synchronous belts, and the power is provided by a traction motor, ensuring the uniformity and stability of the label traction force. At the same time, a limiting roller is set above the traction roller, and the limiting roller is mounted on the concave frame through a second spring and a second telescopic rod. The elastic force of the second spring makes the limiting roller always tightly pressed against the label surface, effectively preventing the label from slipping, wrinkling or deviating from the conveying path during the traction process, ensuring that the label can be stably and smoothly conveyed to the cutting position, thus improving production efficiency. 2. This utility model, through the setting of a positioning and cutting mechanism, has a U-shaped positioning plate in the positioning and cutting mechanism. Before the cutting die is pressed down by the cylinder, the U-shaped positioning plate first contacts the label and presses it into position. Through the buffering effect of the first telescopic rod and the first spring, sufficient clamping force can be ensured while avoiding excessive squeezing and damage to the label. This design effectively avoids label deviation during the cutting process, making the cut label size accurate and the edges neat, greatly improving the cutting quality of the label, reducing the scrap rate, and saving production costs.

[0015] 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.

[0016] Please see Figure 1-4 This utility model provides a technical solution: A label quick cutting and positioning device includes a base 1; two sets of guide frames 2, which are symmetrically fixedly installed on the upper surfaces at both ends of the base 1 along its length, and two sets of guide rollers 21 with different heights are rotatably installed inside for guiding the labels; by setting two sets of guide rollers 21 with different heights, the labels are made to be in a moderately tensile state during the conveying process, avoiding label wrinkles or deviation, and achieving the effect of stable guiding and ensuring the flatness of the label conveying. The positioning and cutting mechanism 3 is installed at the top center of the base 1 and is used to position and cut the label; the traction and limiting mechanism 4 is installed on the base 1 and is used to traction and assist in limiting the label before and after cutting; by setting the positioning and cutting mechanism 3 and the traction and limiting mechanism 4 to work together, the integrated operation of label conveying, positioning and cutting is realized, which improves cutting efficiency and reduces manual intervention. In an optional embodiment: the traction limiting mechanism 4 includes two sets of mounting frames 41; the two sets of mounting frames 41 are symmetrically fixedly installed on the top of the base 1, respectively located on both sides of the positioning and cutting mechanism 3. The lower traction roller 42 is rotatably installed inside the two sets of mounting frames 41 through bearings. One end of each set of traction rollers 42 passes through the mounting frame 41 and is fixedly connected to a synchronous wheel 44. The two sets of synchronous wheels 44 are connected by a synchronous belt drive. The other end of one set of traction rollers 42 passes through the mounting frame 41 and is fixedly connected to a traction motor 43. The mounting frame 41 is located above the traction roller 42 and a limiting roller 45 is rotatably installed. The traction roller 42 cooperates with the limiting roller 45 to traction and assist in limiting the label.

[0017] It should be noted that by setting the transmission structure of the synchronous pulley 44 and the synchronous belt, the rotation speed of the two sets of traction rollers 42 is ensured to be consistent. At the same time, by utilizing the upper and lower cooperation of the traction rollers 42 and the limit rollers 45, the label is pulled smoothly and slipped or deviated during the conveying process.

[0018] In an optional embodiment: the positioning and cutting mechanism 3 includes a support platform 31; the support platform 31 is fixedly installed at the top center of the base 1, and a cutting groove 32 is opened on the surface. A fixing frame 33 is fixedly installed on the top, and a vertically arranged telescopic cylinder 34 is fixedly installed on the top of the fixing frame 33. The bottom of the telescopic end of the cylinder 34 passes through the fixing frame 33 and is fixedly connected to a mounting plate 35. A cutting die 36 is fixedly installed at the bottom center of the mounting plate 35. The cutting die 36 is adapted to the cutting groove 32, and a U-shaped positioning plate 37 is movably installed on the mounting plate 35 below the outer wall of the cutting die 36. This plate is used to press and position the label before cutting to prevent the label from shifting during the cutting process.

[0019] It should be noted that by setting a cutting groove 32 that is precisely matched with the cutting die 36, and in conjunction with the pre-pressing function of the loop positioning plate 37, the effect of neat label cutting edges and accurate dimensions is achieved.

[0020] In an optional embodiment: six sets of first telescopic rods 39 are symmetrically fixedly installed on the bottom of the mounting plate 35 in pairs. The bottom of each of the six sets of first telescopic rods 39 is fixedly connected to the top of the U-shaped positioning plate 37. The outer wall of the first telescopic rod 39 is fitted with a first spring 38. The two ends of the first spring 38 abut against the bottom of the mounting plate 35 and the top of the U-shaped positioning plate 37, respectively.

[0021] It should be noted that by setting up six sets of symmetrically distributed first telescopic rods 39 and first springs 38, the elastic force of the springs is used to make the force on the U-shaped positioning plate 37 uniform when pressing the label. At the same time, the telescopic rods restrict the deformation direction of the springs, thus achieving the effect of flexible pressing and avoiding damage to the label surface.

[0022] In an optional embodiment: guide rods 310 are slidably inserted into both sides of the mounting bracket 33 on the cylinder 34, and the bottom of the guide rods 310 is fixedly connected to the top of the mounting plate 35.

[0023] It should be noted that by setting two sets of symmetrical guide rods 310, the mounting plate 35 is guided to make vertical lifting and lowering movements under the drive of the cylinder 34, so as to achieve the effect of the cutting die 36 accurately aligning with the cutting groove 32 and avoiding cutting deviation.

[0024] In an optional embodiment, two sets of auxiliary rollers 311 are rotatably mounted on both sides of the support platform 31 via brackets, and the top of the auxiliary rollers 311 is flush with the top of the support platform 31 for assisting in the conveying of labels.

[0025] It should be noted that by setting an auxiliary roller 311 that is flush with the support platform 31, the height difference when the label enters and leaves the support platform 31 is eliminated, thus achieving smooth label conveying and avoiding jamming or wrinkling.

[0026] In an optional embodiment: three sets of second springs 46 are fixedly installed at equal intervals on the inner top of the mounting frame 41, and a concave frame 47 is fixedly installed at the bottom of the three sets of second springs 46. The limiting roller 45 is rotatably installed inside the concave frame 47 through a bearing, and the limiting roller 45 and the traction roller 42 are arranged vertically in correspondence. The elastic force of the second springs 46 makes the limiting roller 45 always press against the label surface.

[0027] It should be noted that by setting three sets of equally spaced second springs 46, uniform downward pressure is provided to the limiting roller 45, while adapting to labels of different thicknesses, achieving the effect of adaptive pressing and ensuring traction stability.

[0028] In an optional embodiment: a second telescopic rod 48 is installed inside the second spring 46. The top of the second telescopic rod 48 is fixedly connected to the inner top of the mounting bracket 41, and the bottom is fixedly connected to the top of the concave bracket 47. The second telescopic rod 48 and the second spring 46 are coaxially arranged.

[0029] It should be noted that by setting a coaxial second telescopic rod 48 and a second spring 46, the lateral deformation of the spring is limited, ensuring that the limiting roller 45 always maintains a vertical clamping force, thus achieving structural stability and preventing the limiting roller 45 from shifting.

[0030] Working principle: First, the label material enters from the guide frame 2 at one end of the base 1, and is tensioned and guided by two sets of guide rollers 21 set at different heights to avoid wrinkles during the initial conveying of the label. Then, the label enters the traction limiting mechanism 4. After the traction motor 43 starts, it drives the two sets of traction rollers 42 to rotate synchronously through the synchronous wheel 44 and the synchronous belt. At the same time, the limiting roller 45 presses against the label surface under the elastic force of the second spring 46 to form a stable traction conveying, ensuring that the label moves towards the positioning and cutting mechanism 3 at a preset speed. When the label is conveyed to the surface of the support platform 31, the auxiliary rollers 311 on both sides help the label to smoothly transition to the cutting area. At this time, the cylinder 34 is activated and pushes the mounting plate 35 downward. The U-shaped positioning plate 37 at the bottom of the mounting plate 35 first contacts the label. Under the elastic action of the first spring 38, the label is evenly pressed and positioned to prevent it from shifting during cutting. As the mounting plate 35 continues to descend, the cutting die 36 and the cutting groove 32 on the support platform 31 precisely cooperate to complete the rapid cutting of the label. After cutting, cylinder 34 drives mounting plate 35 to reset, and the loop positioning plate 37 is disengaged from the label under the action of the first spring 38. At the same time, the traction limiting mechanism 4 continues to pull the cut label to the guide frame 2 at the other end of the base 1, and finally outputs the finished label through guide roller 21.

[0031] The control method in this application is through a controller. The controller's control circuit can be implemented by a person skilled in the art through simple programming and is common knowledge in the field. Furthermore, since this application is mainly used to protect the structure, shape, and their combination, this application will not explain the control method and circuit connection in detail.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
