Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a servo punching device based on packaging film processing. Background Technology

[0002] Currently, in the instant noodle packaging process, five loose packets of instant noodles need to be wrapped in a large packaging bag. Before the large packaging bag is made into a large packaging bag by the bag making machine, ventilation holes need to be punched in specific positions on the packaging film. This allows the air inside the bag to be discharged in time through the ventilation holes during the longitudinal sealing and end sealing process. After the ventilation holes are punched, the large packaging bag becomes thinner, which makes it easier for the product inside the bag to move during packaging and thus prevents packaging defects. At the same time, it also facilitates the subsequent automatic boxing process.

[0003] Currently, the punching devices used in the market are mainly pneumatic punching devices. However, pneumatic punching results in large punching impact, inaccurate positioning, and high noise during the punching process, which pollutes the working environment and affects the quality of punching large instant noodle packaging bags. Therefore, we propose a servo punching device based on packaging film processing. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides, for example Figures 1-3The servo punching device for packaging film processing shown includes a frame 100. A guide roller 101 is rotatably mounted on the bottom of the frame 100 to directionally convey the packaging film. Two punching mechanisms are provided on the frame 100, arranged parallel to each other at both ends of the frame 100. The two punching mechanisms are positioned on the left and right sides of the frame 100 to meet the requirement of punching holes on both sides of the packaging film. The punching mechanism includes a rotating blade holder 103 and an anvil 102. The rotating tool holder 103 is fixedly mounted inside the frame 100 and can rotate radially. A cylindrical blade 104 is fixedly mounted on the outer peripheral wall of the rotating tool holder 103. Anvil 102 is arranged parallel to the bottom of the rotating tool holder 103 and can rotate radially. The driving component is mounted on the frame 100 and is used to drive the rotating tool holder 103 to rotate radially. A sensor sensing cam 107 is provided on the frame 100 and is coaxially fixed to the rotating tool holder 103. The front of the sensor sensing cam 107 is aligned with the frame. A 100-phase fixed proximity switch sensor 108 is used. In this embodiment, the punching device can use the encoder feedback signal on the packaging machine to monitor the operation of the packaging film. When the packaging film needs to be punched, it moves to the punching position of the punching mechanism. The drive unit drives the rotating knife holder 103 to rotate, and the rotating knife holder 103 drives the cylindrical knife 104 on its outer peripheral wall to move. The number of cylindrical knife 104 on a single rotating knife holder 103 can be selected and installed according to the usage requirements. The cylindrical knife 104 punches ventilation holes on the packaging film as it rotates with the rotating knife holder 103. Then it stops at the position monitored by the proximity switch sensor 108 on the sensor sensing cam 107 connected to the rotating knife holder 103 shaft, waiting for the next signal from the hole system monitored by the encoder of the packaging machine. This cycle is repeated to realize the continuous ventilation hole punching operation on the packaging film. The entire ventilation hole punching process is accurately positioned, runs smoothly, and has low noise, thus improving the work quality of ventilation hole punching on the packaging film.

[0029] The driving components include a servo geared motor 105 and a transmission gearbox 106. The servo geared motor 105 is fixedly mounted above the rotary tool holder 103, and the transmission gearbox 106 is located at one end of the rotary tool holder 103 and the servo geared motor 105. The rotation shaft of the servo geared motor 105 drives the rotary tool holder 103 to rotate via the transmission gearbox 106. Figure 2 As shown, the transmission gearbox 106 generally contains three gears. The upper and lower gears are coaxially fixed with the servo geared motor 105 and the rotary tool holder 103, respectively, while the middle gear transmits power between the upper and lower gears, so that when the servo geared motor 105 is running, it can drive the rotary tool holder 103 to rotate smoothly through the transmission gearbox 106.

[0030] Furthermore, a support base 110 is fixedly provided on the frame 100, and an anvil shaft 109 is fixedly provided on the top of the support base 110. The anvil 102 is rotatably sleeved on the outer wall of the anvil shaft 109. A pressure adjusting assembly is provided on the support base 110 to adjust the pressing force of the anvil 102 on the packaging film. The pressure adjusting assembly includes an adjusting bolt 111 and an elastic spring 112. The outer wall of the adjusting bolt 111 is threaded into the bottom end of the support base 110, and the top end of the adjusting bolt 111 extends upward and is movably inserted into a hole at the end of the anvil shaft 109. The elastic spring 112 is sleeved on the top of the outer wall of the adjusting bolt 111, and the top end of the elastic spring 112 abuts against the end of the anvil shaft 109. In this embodiment, as shown... Figure 3 As shown, the anvil wheel 102 is tangent to the cylindrical blade 104, which can meet the requirements for punching ventilation holes on the packaging film. At the same time, by rotating the adjusting bolt 111 clockwise or counterclockwise, the distance of the adjusting bolt 111 inserted into or withdrawn from the hole at the end of the anvil wheel shaft 109 can be controlled, thereby adjusting the compression amount of the elastic spring 112 and changing the elastic squeezing force of the elastic spring 112 on the anvil wheel shaft 109. This achieves the adjustment of the squeezing force on the packaging film on the anvil wheel shaft 109, making the operation of punching ventilation holes on the packaging film by the anvil wheel 102 and the cylindrical blade 104 on the rotating blade holder 103 more precise and stable.
