Description

Technical Field

[0001] This utility model relates to an automatic punching and venting device for film packaging, belonging to the technical field of household appliance packaging equipment. Background Technology

[0002] Currently, household appliances are often packaged with heat-shrink film before leaving the factory. To prevent the air inside the film from expanding due to heat, causing the film to bulge or rupture, it is necessary to punch holes in the packaging film to release air after application. Existing technologies mostly use fixed drill bits or needle plates for punching, which has significant drawbacks: First, it cannot flexibly adapt to household appliances of different sizes and shapes, resulting in inaccurate punching positions and significant waste of film material; second, rigid contact easily scratches the product surface, leading to poor punching accuracy; third, when changing product specifications, adjustments are time-consuming, severely restricting production efficiency. Therefore, developing a punching and air-venting device that can automatically adjust, precisely align, and protect the product is particularly urgent. Utility Model Content

[0003] This invention overcomes the shortcomings of the existing technology and provides an automatic punching and venting device for film packaging that has a reasonable structure, convenient adjustment, and high punching accuracy.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an automatic punching and venting device for film packaging, comprising: A perforated movable substrate is used for fixed installation at the perforation station of a film-coating machine; A punching wheel slide rail assembly is mounted on the punching movable base plate; The punching mechanism moving seat is mounted on the punching wheel slide rail assembly and is driven by it to move. A punching wheel assembly, mounted on the punching mechanism movable seat, is used to punch holes in the packaging film; The punching wheel assembly includes a punching wheel base plate, a punching wheel shaft, a punching roller, and a plurality of punching pins disposed on the punching roller; the punching wheel base plate is connected to the punching mechanism movable seat, and the punching roller is rotatably mounted on the punching wheel base plate via the punching wheel shaft.

[0005] Furthermore, the corresponding perforating wheel shaft is arranged in the guide groove of the perforating wheel seat plate, and a buffer spring is provided between the perforating wheel seat plate and the perforating wheel shaft.

[0006] Furthermore, the perforating wheel slide rail assembly includes a track and a slider, the slider slidingly engaging with the track and being driven by a ball screw transmission mechanism.

[0007] Furthermore, the punching needles are distributed in a spiral pattern on the surface of the punching roller.

[0008] Furthermore, there are multiple perforating rollers, which are sequentially and movably connected on the perforating roller shaft.

[0009] Furthermore, the ball screw transmission mechanism is connected to a drive motor and controlled by a PLC control system, which is used to precisely control the movement trajectory of the slider and the moving seat of the punching mechanism according to a preset program.

[0010] Furthermore, the punching wheel slide rail assembly includes a first driving structure for driving the punching mechanism moving seat to move laterally back and forth and a second driving structure for moving vertically up and down. The punching mechanism moving seat can perform a combined forward and backward and up and down motion under the drive of the punching wheel slide rail assembly.

[0011] Compared with the prior art, the advantages of this utility model are as follows: This utility model realizes automatic adjustment of the punching position through PLC control, which can adapt to the packaging needs of products of different specifications; it adopts high-precision ball screw transmission to reduce punching errors and avoid damage to the product surface; the equipment changeover time is shortened and it supports rapid switching in mixed production mode; the punching of this utility model is uniform and the waste rate of film material is greatly reduced; the components are organically combined, the operation is stable, and the maintenance is simple.

Detailed Implementation

[0018] The present invention will be further described below with reference to specific embodiments.

[0019] like Figures 1 to 4As shown, this utility model discloses an automatic punching and venting device for film packaging. The punching moving base plate 1 is firmly installed on the punching station frame of the high-speed film packaging machine.

[0020] The perforating wheel slide rail assembly 2 is mounted entirely on the perforating moving base plate 1. This assembly includes a first drive structure 5 for lateral (forward and backward) movement and a second drive structure 6 for vertical (up and down) movement. Both the first drive structure 5 and the second drive structure 6 preferably employ high-precision ball screw pairs driven by servo motors (the screw and nut are not shown separately in the figure), thus forming a precision two-dimensional moving platform. The rail 21 and the slider 22 are key guiding components of this platform, ensuring smooth and precise movement.

[0021] The punching mechanism moving seat 3 is fixedly mounted on the slider 22, so it can be driven to perform precise compound movements in a two-dimensional plane to reach the preset punching position.

[0022] The punching wheel assembly 4 is connected to the punching mechanism moving seat 3 via its punching wheel seat plate 41. The punching wheel shaft 42 is not rigidly fixed, but rather mounted within a guide slot 45 on the punching wheel seat plate 41 and connected to the seat plate via a buffer spring 46. This design makes the entire punching roller assembly 43 a floating body; when encountering uneven product surfaces, it can slightly compress the spring and move along the slot, preventing the punching needle 44 from excessively penetrating or scratching the product. Multiple punching rollers 43 can be connected in series on a single punching wheel shaft 42 to increase the punching width.

[0023] The perforating pins 44 are evenly distributed in a spiral pattern on the circumferential surface of the perforating roller 43. This arrangement makes the perforation process continuous and gradual, rather than instantaneous impact, which is beneficial for uniform degassing of the membrane and stable operation of the equipment.

[0024] During operation, the PLC control system calls a preset program to control the perforating wheel slide rail assembly 2 to drive the perforating mechanism moving seat 3 and the perforating wheel assembly 4 to move to the target position. As the conveyor line carries the film products past, the perforating roller 43 rolls on the film surface, and the perforating needle 44 completes flexible and uniform perforation under the action of the buffer mechanism.

[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
