Description

Technical Field

[0001] The utility model relates to the technical field of labeling machines, in particular to a flat labeling machine with high-precision positioning. Background Technique

[0002] A flat labeling machine is a device specifically used to paste paper or metal foil labels on specified packaging containers through adhesives. When the flat labeling machine is in use, the sensor detects the passing of the product and transmits a signal to the labeling control system. Within a specified time, the control system controls the motor to send out the label and attach it to the position on the product where the label is to be attached. Subsequently, the product flows through the label covering device, and the label is tightly pressed, completing the attachment action of one label; currently, the flat labeling machine is applicable to the automatic labeling of both sides of various flat and square products and the circumferences of round bottles in the food, daily chemical, pharmaceutical, and other light industrial industries.

[0003] The conveying system is one of the important component structures of the flat labeling machine, and its main function is to convey the product. When the conveyor belt conveys the product to the position where the label is to be attached, the conveyor belt stops moving, and the labeling component then labels the product; however, in the process of conveying the product by the existing conveying system, although corresponding limiting structures are provided to enable the product to move along a predetermined trajectory, in the actual use process, the limiting effect of the limiting structure is limited, and the product moving along the conveyor belt has a position deviation when it is conveyed to the position where the label is to be attached, thereby affecting the accuracy of labeling. In view of this, we propose a flat labeling machine with high-precision positioning. Content of the Utility Model

On the right vertical plate 20, a motor 23 for driving the double-headed screw rod 22 to rotate is installed; on both threaded ends of the double-headed screw rod 22, a support plate 24 is threadedly connected. At the top of the support plate 24, a cross plate 25 is fixed. At both ends of the cross plate 25, guide rods 26 are fixed. Between the ends of the two guide rods 26, a limiting plate 27 for restricting the movement track of the product on the top of the conveyor 10 is fixed. At the rear end of the limiting plate 27, there is a bent part 271 inclined to one side; on the top of the limiting plate 27, ear plates 28 are fixed. On one ear plate 28, an infrared emission module 281 is installed, and on the other ear plate 28, an infrared receiving module 282 is installed; on both sides of the conveyor 10 near the front end, a product fixing part 3 is installed. The product fixing part 3 includes two symmetrically arranged fixing frames 30 fixed to the machine body 1. On the top of the fixing frame 30, an electric cylinder 31 is installed. At the ends of the piston rods of the electric cylinder 31, fixing blocks 32 are installed. On one side of the fixing block 32, a detachable movable seat 33 is provided. At the bottom end of one side wall of the movable seat 33, a clamping block 34 is installed. On the clamping block 34, a clamping groove 341 for clamping the product is provided.

[0034] In this embodiment, a fixing groove is formed at the top of the fixing block 32; a connecting block 332 is installed at the top end of one end surface of the movable seat 33 close to the fixing block 32. The connecting block 332 is inserted into the connecting block 332, and a fixing bolt 333 is passed through the connecting block 332, and the fixing bolt 333 is threadedly connected to the fixing block 32. This design facilitates the disassembly and assembly of the movable seat 33 and the clamping block 34, so as to conveniently replace the appropriate clamping block 34 according to the size of the product.

[0035] In this embodiment, a fixing hole 301 is formed at the bottom end of the fixing frame 30, and a connecting bolt threadedly connected to the machine body 1 is passed through the fixing hole 301. Through the fixing hole 301 and the connecting bolt threadedly connected to the machine body 1, the firm connection between the fixing frame 30 and the machine body 1 is ensured. This connection method is simple and reliable, and can effectively prevent the fixing frame 30 from loosening or shifting during use.

[0036] In this embodiment, the limiting plate 27 and the bending portion 271 are of an integrally formed structure, and both the limiting plate 27 and the bending portion 271 are made of plastic material. This design improves the structural stability. At the same time, the selection of plastic material ensures its light weight and certain durability, and is not easy to cause damage to the product.

[0037] In this embodiment, the other end of the guide rod 26 passes through the vertical plate 20 and is slidably connected to the vertical plate 20, and a limiting block is coaxially fixed at the other end of the guide rod 26. This design plays a guiding role in the horizontal movement of the cross plate 25, ensuring the stability of the cross plate 25, and the limiting block can prevent the guide rod 26 from detaching from the vertical plate 20.

[0038] In this embodiment, two diagonal braces 11 are fixedly connected to both the front and rear ends between the conveyor 10 and the machine body 1 by bolts, and the diagonal braces 11 are inclined.

[0042] It should be noted that the motor 23 involved in this embodiment is an existing conventional technology and will not be elaborated here.

[0043] Before specific use, the user first turns on the power supply of the motor 23. The motor 23 starts to work. The output shaft of the motor 23 rotates to drive the double-headed lead screw 22 to rotate. As the double-headed lead screw 22 rotates, the two side support plates 24 move synchronously relative to each other. The support plates 24 drive the cross plate 25 to move at the same time. The cross plate 25 drives the guide rod 26 to move. The guide rod 26 drives the two side limiting plates 27 to move synchronously. As the two side limiting plates 27 move synchronously relative to each other, the distance between the two limiting plates 27 changes. When the distance between the two limiting plates 27 moves to an appropriate distance, the user turns off the power supply of the motor 23.

[0044] During specific use, the user first turns on the power supply of the conveyor 10. The conveyor 10 starts to work. The conveyor belt of the conveyor 10 drives the product to move forward at the same time. When the product passes through the sensor 40, the sensor 40 transmits a signal to the labeling control system. The labeling control system controls the operation of the two side electric cylinders 31. The electric cylinders 31 drive the two side fixed blocks 32 and the movable seats 33 to move synchronously relative to each other. The movable seat 33 drives the clamping blocks 34 to move at the same time. The two side clamping blocks 34 clamp and fix the product. At the same time, the labeling control system controls the conveyor 10 to stop moving. Finally, the labeling system labels the fixed product.

[0045] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and do not limit the present invention.
