Description

Technical Field

[0001] The utility model relates to the technical field of printing tear lines, in particular to an instant online printing tear line mechanism. Background Art

[0002] In the packaging industry, the addition of tear lines is a common process used to facilitate consumers to open the package. The traditional method of adding tear lines usually requires a separate process on the production line to add tear lines to the packaging material manually or mechanically before proceeding to the subsequent packaging process. This method not only increases production costs, but also reduces production efficiency. At the same time, since the position of the tear line needs to be precisely controlled, the traditional method often has difficulty in ensuring the position accuracy of the tear line, resulting in inconvenient opening or poor appearance of the final product.

[0003] Existing deficiencies:

[0004] Due to the limitations of traditional tear line adding methods, manufacturers are faced with the dual challenges of improving production efficiency and ensuring the accuracy of tear line positioning. On the one hand, the separate tear line adding process increases production time and cost; on the other hand, it is difficult to achieve high-precision tear line positioning by manual or traditional mechanical methods, which affects product quality and consumer experience. Therefore, the development of an instant online printing tear line mechanism that can accurately add tear lines directly to packaging materials under normal production conditions, which not only improves production efficiency but also ensures the accuracy of tear line positioning, has become an urgent problem that needs to be solved in the packaging industry. To this end, the utility model proposes an instant online printing tear line mechanism to solve the above problems. Utility Model Content

[0005] In order to overcome the defects of the prior art, the purpose of the utility model is to provide an instant online printing tear line mechanism to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is implemented as follows: a real-time online printing tear line mechanism, comprising:

[0007] A fixing plate, wherein the fixing plates are two;

[0008] A compression spring, one end of which is fixed to one of the fixing plates, and a one-way roller is mounted on the other end of the compression spring;

[0009] A film winding drum, the film winding drum is mounted on another fixed plate, and a height adjustment rod is provided on one side of the film winding drum;

[0010] A fixed knife seat is arranged on one side of the film winding drum, a cylinder is fixed on one side of the fixed knife seat, and a toothed blade is connected to the output end of the cylinder.

[0011] Preferably, the outer surface of the one-way roller has a friction enhancing material.

[0012] Preferably, the length of the height adjustment rod is adjustable.

[0013] Preferably, the cylinder is a bidirectional cylinder.

[0014] The beneficial effects of the utility model are embodied in:

[0015] High efficiency and immediacy: The mechanical design supports the instant printing of tear lines at designated locations during the film's passage, thereby improving production efficiency and meeting the needs of rapid production. This immediacy is particularly important for time-sensitive products on the production line, which can reduce production delays and speed up the overall production process.

[0016] Simple structure and easy maintenance: Since the mechanism uses simple fixed plates, compression springs, one-way rollers, film winding rollers and fixed knife seats and other basic components, the entire mechanism is not only simple in structure, but also easy to install, debug and maintain. The simplified mechanical structure reduces possible failure points and improves the stability of the equipment and the reliability of long-term operation.

[0017] Precise positioning, high tear line quality: The toothed blade controlled by the cylinder can accurately print the tear line on the film, ensuring the quality and consistency of the tear line. The precise positioning mechanism also allows the position of the tear line to be adjusted as needed, providing greater flexibility to adapt to different product designs and functional requirements.

[0018] In summary, the instant online printing tear line mechanism not only improves the efficiency and quality of production, but also has the advantages of simple structure, easy maintenance, precise positioning, strong adaptability and safe operation. It is a practical new mechanical structure with a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] It should be noted that if the utility model embodiments involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

Example

[0026] Please refer to the instruction manual Figure 1 The utility model provides an instant online printing tear line mechanism, specifically:

[0027] Main structure composition:

[0028] Fixed plate 8: The two fixed plates serve as the support of the main structure to stabilize the entire mechanism.

[0029] Compression spring 7: one end is fixed to one of the fixed plates 8, and the other end is mounted with a one-way roller 6, which provides the necessary tension to keep the material passing smoothly.

[0030] One-way roller 6: The outer surface is covered with friction enhancing material to ensure that the material will not slip when passing through, ensuring the accuracy of the tearing line.

[0031] Film winding drum 5: mounted on another fixed plate 8, used for guiding and storing the material to be printed.

[0032] Height adjustment rod 4: It is arranged on one side of the film winding roller 5, and its length is adjustable to adapt to materials of different thicknesses and ensure smooth passage of the materials.

[0033] Fixed blade holder 1: arranged at one side of the film winding roller 5, used for fixing the toothed blade 2.

[0034] Cylinder 3: A bidirectional cylinder fixed on the fixed knife holder 1, with a toothed blade 2 connected to its output end for controlling the cutting action of the blade.

[0035] Control system:

[0036] The mechanism is managed by an integrated control system, including the triggering timing of the cylinder 3, the speed adjustment of the film winding roller 5 and the position adjustment of the height adjustment rod 4, so as to achieve precise operation on a high-speed production line.

[0037] Directions:

[0038] First, adjust the height adjustment rod 4 and the fixed plate 8 to reach the desired position, and use the compression spring 7 to support the one-way roller 6 to press the film-winding roller 5. After the film moves forward, it cannot rebound due to the action of the one-way roller 5, ensuring that the rear end film is always in a taut state. The film passes between the fixed knife seat 1 and the toothed blade 2. Every time the film moves as needed, the cylinder 3 drives the toothed blade to move once, cutting small holes of equal size and spacing on the film to facilitate tearing.

[0039] Through this design, the instant online printing tear line mechanism can meet the production requirements of high efficiency and high precision, and is particularly suitable for fast packaging production lines, thereby improving production efficiency and product appearance quality.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
