Description

Technical Field

[0001] The utility model relates to the technical field of labeling, in particular to a label pressing device for labeling. Background Art

[0002] Labels are a direct means of providing consumers with product information. On the one hand, they effectively provide a basis for consumer choice and protect their interests. On the other hand, they effectively demonstrate the company's commitment to implementing national standards and avoid losses caused by labeling errors. Therefore, before leaving the factory, products are labeled. After labeling, a pressing device is often used to strengthen the label's fit and improve labeling effectiveness.

[0003] Patent No. CN219339987U discloses a packaging carton label pressing structure, which relates to the technical field of label pressing structures, including a workbench and a conveyor belt arranged at the upper end of the workbench. Pressing components are fixedly installed on both sides of the upper end of the outer wall of the workbench, which solves the problem that the operator needs to press after labeling so that the attached label can be firmly adhered to the upper end. This reciprocating operation easily consumes the operator's physical strength, and the manual pressing is not in place, which easily affects the firmness of the label. The operator can directly place the labeled packaging carton on the conveyor belt, and the packaging carton is transported to the lower end of the U-shaped clamping block through the conveyor belt. The soft rubber column will contact the packaging carton transported by the conveyor belt, and press the label on the upper end of the packaging carton. The soft rubber column is a component made of rubber material and will not damage the label. The operator can adjust the height of the micro-electric telescopic rod according to the size of the packaging carton, thereby driving the U-shaped clamping block and the soft rubber column to adjust the height, thereby improving the applicability of the soft rubber column.

[0004] However, the above-mentioned packaging carton label pressing structure still has the following shortcomings:

[0005] The above-mentioned device uses several soft rubber columns to press the label on the upper end of the packaging carton. However, when the soft rubber columns contact the packaging carton, they increase the friction between the packaging carton and the packaging carton, which hinders the movement of the packaging carton and easily causes the packaging carton to overturn, affecting the label pressing progress. In view of this, we propose a label pressing device for labeling. Utility Model Content

[0006] The purpose of the utility model is to overcome the shortcomings of the existing technology, meet the actual needs, and provide a label pressing device for labeling to solve the technical problem that the current device uses a plurality of soft rubber columns to press the label on the upper end of the packaging carton. However, the soft rubber columns increase the friction between the packaging carton and the packaging carton when contacting the packaging carton, so that the movement of the packaging carton is correspondingly hindered, which easily causes the packaging carton to overturn and affects the progress of label pressing.

[0007] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is as follows: a label pressing device for labeling is designed, including a base, a conveyor belt is provided inside the base, an adjustment mechanism is provided on the top of the base, and a pressing component is engaged with the inner side of the adjustment mechanism;

[0008] The pressing assembly includes a pressing cylinder, which is arranged on the inner side of the adjusting mechanism. A group of shaft rods are symmetrically fixedly connected to both ends of the pressing cylinder. A rubber ring is provided on the outer side of the pressing cylinder. A group of limiting grooves are symmetrically opened inside the shaft rods. A guide rod is fixedly connected to the middle end of the limiting groove. A spring is provided on the outer side of the guide rod. A card block is matched and engaged inside the limiting groove. A movable rod is fixedly connected to the top of the card block. A sliding groove is provided on the outer side of the movable rod.

[0009] Preferably, the length of the guide rod is the same as the depth of the limiting groove, a slot matching the diameter of the guide rod is provided inside the clamping block, and the clamping block is in a cross shape.

[0010] Preferably, the clamping block forms an elastic structure through a spring and a limiting groove, and the clamping block forms a sliding structure through a movable rod and a sliding groove.

[0011] Preferably, the adjustment mechanism includes a hydraulic cylinder, and two groups of the hydraulic cylinders are symmetrically embedded on the inner side of the top of the base. The movable ends of the hydraulic cylinders are connected to support plates, and a group of I-frames are symmetrically clamped inside a group of support plates. One end of the I-frame is connected to a motor, and a positioning frame is provided on the outside of the motor.

[0012] Preferably, the support plate and the base form a lifting structure through a hydraulic cylinder, and the workpiece frame can rotate freely inside the support plate.

[0013] Preferably, a slot is provided on the inner side of one end of the I-shaped frame close to the shaft, and the exposed portion of the block is matched and engaged in the slot at the end of the I-shaped frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model effectively drives the pressing assembly to rotate clockwise through the adjusting mechanism, and at the same time the transmission belt rotates counterclockwise and at the same speed as the pressing assembly, so that the pressing cylinder and the rubber ring can press the labels on the surface of the articles without affecting the transmission of the articles, thereby improving the transmission stability. When the pressing cylinder or the rubber ring needs to be repaired and replaced, the movable rod is pulled close to the pressing cylinder, and the movable rod drives the card block to move until the card block is completely hidden in the limit groove. At this time, the pressing assembly can be directly separated from the adjusting mechanism, which is relatively fast and convenient. When installing a new pressing cylinder, the shaft rod is pressed against the inner middle surface of the adjusting mechanism on the basis of pulling the movable rod, and then the movable rod is released. Under the influence of the spring rebound force, the card block is partially ejected and effectively engaged with the inside of the adjusting mechanism, thereby quickly completing the limitation of the pressing cylinder.

[0016] 2. The utility model effectively drives the support plate to move up and down through the hydraulic cylinder, thereby driving the pressing assembly on the inner side of the support plate to move up and down, making it easy to adjust the distance between the pressing assembly and the conveyor belt, so as to adapt to pressing labels on the surfaces of objects of different heights. Since the exposed part of the card block matches and engages in the cross card slot at the end of the I-frame, when the motor is started, it effectively drives the I-frame and the pressing assembly to rotate, so that the pressing assembly can achieve auxiliary transportation of objects.

[0024] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0025] A label pressing device for labeling, see Figures 1 to 4 , comprising a base 1, a conveyor belt 2 is provided inside the base 1, an adjustment mechanism 3 is provided on the top of the base 1, and a pressing component 4 is engaged with the inner side of the adjustment mechanism 3;

[0026] The pressing component 4 includes a pressing cylinder 401, which is arranged on the inner side of the adjusting mechanism 3. A group of shaft rods 402 are symmetrically fixedly connected at both ends of the pressing cylinder 401. A rubber ring 403 is provided on the outside of the pressing cylinder 401. A group of limiting grooves 404 are symmetrically opened inside the group of shaft rods 402. A guide rod 405 is fixedly connected to the middle end of the limiting groove 404. A spring 406 is provided on the outside of the guide rod 405. A clamping block 407 is matched and engaged with the inside of the limiting groove 404. The length of the guide rod 405 is the same as the depth of the limiting groove 404. A slot hole matching the diameter of the guide rod 405 is opened inside the clamping block 407. The clamping block 407 is cross-shaped. A movable rod 408 is fixedly connected to the top of the clamping block 407. A sliding groove 409 is provided on the outside of the movable rod 408. Furthermore, the clamping block 407 forms an elastic structure with the limiting groove 404 through the spring 406, and the clamping block 407 forms a sliding structure with the sliding groove 409 through the movable rod 408. The utility model effectively drives the pressing assembly 4 to rotate clockwise through the adjusting mechanism 3, and the conveyor belt 2 rotates counterclockwise and at the same speed as the pressing assembly 4, so that the pressing cylinder 401 and the rubber ring 403 can press the label on the surface of the article without affecting the transmission of the article, thereby improving the transmission stability. When the pressing cylinder 401 or the rubber ring 403 needs to be repaired and replaced, the movable rod 408 is pulled close to the pressing cylinder 401, and the movable rod 408 drives the card block 407 to move until the card block 407 is completely hidden in the limit groove 404. At this time, the pressing assembly 4 can be directly separated from the adjusting mechanism 3, which is relatively fast and convenient. When installing a new pressing cylinder 401, the shaft rod 402 is pressed against the inner middle surface of the adjusting mechanism 3 on the basis of pulling the movable rod 408, and then the movable rod 408 is released. Under the influence of the rebound force of the spring 406, the card block 407 partially pops out and effectively engages with the inside of the adjusting mechanism 3, quickly completing the limitation of the pressing cylinder 401.

[0027] It is worth noting that the adjustment mechanism 3 includes a hydraulic cylinder 301, and two groups of hydraulic cylinders 301 are symmetrically embedded on the inner side of the top of the base 1. The movable end of the hydraulic cylinder 301 is connected to a support plate 302, and a group of I-frames 303 are symmetrically clamped inside a group of support plates 302, wherein the support plates 302 form a lifting structure with the base 1 through the hydraulic cylinder 301, and the I-frame 303 can rotate freely inside the support plate 302. Furthermore, a slot is provided on the inner side of one end of the I-frame 303 close to the shaft 402, and the exposed part of the block 407 matches and fits in the slot at the end of the I-frame 303. A motor 304 is connected to the end of the I-frame 303 on one side, and a positioning frame 305 is provided on the outside of the motor 304. The utility model effectively drives the support plate 302 to move up and down through the hydraulic cylinder 301, thereby driving the pressing component 4 inside the support plate 302 to move up and down, making it easy to adjust the distance between the pressing component 4 and the conveyor belt 2, so as to adapt to pressing labels on the surfaces of objects at different heights. Since the exposed part of the card block 407 matches and engages with the cross card slot at the end of the I-frame 303, when the motor 304 is started, it effectively drives the I-frame 303 and the pressing component 4 to rotate, so that the pressing component 4 can achieve auxiliary transportation of objects.

[0028] Working principle: The hydraulic cylinder 301 drives the support plate 302 to move up and down, thereby driving the pressing component 4 inside the support plate 302 to move up and down, so as to adjust the distance between the pressing component 4 and the conveyor belt 2, so as to adapt to the pressing of labels on the surfaces of objects at different heights. After that, the motor 304 is started, and the motor 304 drives the work frame 303 and the pressing component 4 to rotate clockwise, while the conveyor belt 2 rotates counterclockwise and at the same speed as the pressing component 4, so that the pressing cylinder 401 and the rubber ring 403 can press the labels on the surface of the objects without affecting the transmission of the objects. If the pressing cylinder 4 needs to be repaired and replaced 01 or rubber ring 403, pull the movable rod 408 toward the pressure cylinder 401, and the movable rod 408 drives the block 407 to move until the block 407 is completely hidden in the limit groove 404. At this time, the covering component 4 can be directly separated from the adjustment mechanism 3. When installing a new pressure cylinder 401, the shaft 402 is pressed against the inner middle surface of the adjustment mechanism 3 on the basis of pulling the movable rod 408, and then the movable rod 408 is released. Under the influence of the rebound force of the spring 406, the block 407 partially pops out and engages with the inside of the adjustment mechanism 3, quickly completing the limitation of the pressure cylinder 401.
