Description

Technical Field

[0001] This utility model relates to the field of plastic film technology, and in particular to a plastic film labeling device. Background Technology

[0002] Plastic films are thin film materials typically used for packaging, protecting, and covering items. They can be made of different types of plastics such as polyethylene, polypropylene, and polyvinyl chloride. The characteristics of plastic films include softness, transparency, water resistance, chemical resistance, and a certain degree of tear resistance, making them applicable in various fields.

[0003] Currently, each piece of plastic film is usually printed with the manufacturer's corresponding logo. The plastic film is then printed and cut to the required length. However, the printing equipment and the cutting equipment are usually not on the same production line, which causes some inconvenience to the processing.

[0004] Existing plastic film labeling equipment suffers from the following drawbacks: It lacks a single functionality and an integrated cutting structure to facilitate labeling operations, requiring the plastic film to be transferred to a cutting production line. This results in the high space cost associated with separate labeling and cutting equipment. Therefore, we propose a plastic film labeling device. Summary of the Invention

[0005] The main objective of this invention is to provide a plastic film labeling device that can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A plastic film labeling device includes a mounting frame, an upper discharge roller, and a lower discharge roller, as well as a label holder, a label pressing plate, and an electric heating plate. The mounting frame has an opening at its top, and mounting ears are fixedly provided at both ends of the mounting frame away from the opening. The upper and lower discharge rollers are respectively rotatably mounted at the top and bottom between the mounting ears via bearings. The label holder is bolted to the bottom of the mounting frame away from the opening. The electric heating plate is fixedly embedded in the label holder, and raised characters are provided on the outer side of the electric heating plate.

[0008] Furthermore, the printing plate is disposed on one side of the printing base, and a groove corresponding to the raised character is formed on one side of the printing plate.

[0009] Furthermore, pneumatic push rods are respectively embedded at both ends of the mounting frame away from the label holder. The sleeve cylinder of the pneumatic push rod is fixedly connected to the mounting frame, and the output end of the pneumatic push rod is fixedly connected to the end of the label pressure plate.

[0010] Furthermore, a blade a is fixedly installed at the bottom of the label holder, and a blade b corresponding to blade a is fixedly installed at the bottom of the label pressure plate.

[0011] Furthermore, a motor is provided on one side of the mounting frame, the motor housing is installed and connected to the mounting ear at the corresponding position, and the drive end of the motor is installed and connected to the rotating shaft of the upper discharge roller.

[0012] Furthermore, a heat insulation plate is provided between the label holder and the electric heating plate.

[0013] Compared with the prior art, this utility model has the following advantages: The assembly consisting of a mounting frame, upper discharge roller, lower discharge roller, label holder, label pressure plate, and electric heating plate provides an integrated labeling and cutting structure for plastic film processing. After the plastic film is pushed out by the upper and lower discharge rollers, it is pressed onto the label holder by the label pressure plate. The electric heating plate with raised characters on the label holder heat-presses the plastic film with labels, while simultaneously cutting the plastic film with blades A and B. This integrates the labeling and cutting operations, improving work efficiency and eliminating the need for additional cutting equipment lines, thus reducing the space cost of processing equipment. It also solves the problem of the limited functionality of existing plastic film heat-printing and labeling equipment, which lacks an integrated cutting structure to assist workers during labeling and requires transferring the plastic film to a cutting line, resulting in high space costs for separate labeling and cutting equipment.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1-3 As shown, a plastic film labeling device includes a mounting frame 1, an upper discharge roller 4 and a lower discharge roller 5, and also includes a label holder 6, a label pressing plate 9 and an electric heating plate 7. The mounting frame 1 has an opening 2 at its top, and mounting ears 3 are fixedly provided at both ends of the mounting frame 1 away from the opening 2. The upper discharge roller 4 and the lower discharge roller 5 are respectively rotatably mounted at the top and bottom between the mounting ears 3 via bearings. The label holder 6 is bolted to the bottom of the mounting frame 1 away from the opening 2. The electric heating plate 7 is fixedly embedded in the label holder 6, and raised characters 8 are provided on the outer side of the electric heating plate 7.

[0020] The printing plate 9 is located on one side of the printing base 6, and a groove 10 corresponding to the raised character 8 is provided on one side of the printing plate 9.

[0021] Among them, pneumatic push rods 11 are respectively embedded at both ends of the mounting frame 1 away from the label holder 6. The sleeve cylinder of the pneumatic push rod 11 is fixedly connected to the mounting frame 1, and the output end of the pneumatic push rod 11 is fixedly connected to the end of the label pressure plate 9.

[0022] The bottom of the label holder 6 is fixedly equipped with a blade 12, and the bottom of the label pressure plate 9 is fixedly equipped with a blade 13 corresponding to the blade 12.

[0023] The mounting bracket 1 has a motor 14 on one side. The housing of the motor 14 is connected to the mounting ear 3 at the corresponding position. The drive end of the motor 14 is connected to the rotating shaft of the upper discharge roller 4.

[0024] A heat insulation plate is provided between the label holder 6 and the electric heating plate 7.

[0025] It should be noted that this utility model is a plastic film labeling device. During operation, the operator inserts the plastic film to be labeled through the opening 2 and into the space between the upper discharge roller 4 and the lower discharge roller 5. The motor 14 drives the upper discharge roller 4 to rotate, automatically pushing out the plastic film placed between the upper discharge roller 4 and the lower discharge roller 5. Simultaneously, the pushed-out plastic film falls between the labeling seat 6 and the labeling pressure plate 9. Heating by the electric heating plate 7 generates heat in the raised characters 8. The output end of the pneumatic push rod 11 retracts, causing the labeling pressure plate 9 to press the plastic film onto the labeling seat 6. At the same time, the raised characters 8, under high temperature, thermally print a mark on the plastic film. The specific character style of the starting character 8 is set according to the actual processing requirements. During the process, the processing personnel can install the a blade 12 and the b blade 13 at the bottom of the label holder 6 and the label pressure plate 9 respectively, depending on whether the plastic film needs to be cut. This allows the plastic film to be cut by the a blade 12 and the b blade 13 while the label pressure plate 9 and the label holder 6 are pressed together, so that each piece of plastic film is simultaneously heat-printed with a label. This effectively integrates the label printing and cutting operations. Furthermore, the electric heating plate 7 can be turned off later according to the usage requirements, and the plastic film can be cut separately by the a blade 12 and the b blade 13. This method is highly flexible and easy to operate.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
