Description

Technical Field

[0001] The utility model relates to the technical field of sterilization bag processing equipment, in particular to an automatic segmentation structure for a sterilization bag. Background Art

[0002] Sterilization bags are sterilized packaging bags, usually made of sterile materials, with good airtightness, anti-aging, not easy to break, moisture-proof, dust-proof, insect-proof, and transparent, uniform and flawless, which can ensure that the items are not contaminated and lost during the sterilization process. During the production process, the sterilization bags are first transported to the cutting position, and the positioning device ensures that they are in the correct position. Then, the cutting device is started to cut the sterilization bags with a high-speed rotating blade or laser cutter.

[0003] There are many existing technologies for sterilization bag cutting devices, such as:

[0004] Chinese patent announcement No. CN213648897U discloses a cutting device for producing medical sterilization packaging bags, which includes a workbench, a first fixed column and a second fixed column. The first fixed column is arranged on one side of the workbench, and the second fixed column is arranged on one side of the workbench. By setting a clamping structure, the device is automated, the work efficiency is improved, and the length of the cut packaging bag is always consistent. By setting a first limit plate, the packaging bag is compacted and the packaging bag is prevented from tilting during the pulling process.

[0005] Since the surface material of the sterilization bag is relatively smooth, if the position of the sterilization bag is offset during the cutting process, the sterilization bag will have uneven cuts and become defective, thus affecting the yield of the sterilization bag manufacturer. If the side edge of the sterilization bag is fixed by a fixing mechanism before cutting, it is difficult to achieve automatic continuous cutting, which will seriously slow down the efficiency of the sterilization bag production line. For example, the cutting device for the production of medical sterilization packaging bags proposed in the above patent fixes the packaging bag through a clamping structure, but cannot achieve automatic loading of the sterilization bag, and still cannot take into account both processing efficiency and yield.

[0006] In view of this, we propose an automatic segmentation structure for sterilization bags to improve the shortcomings of the existing technology. Utility Model Content

[0030] Working principle: When the automatic sterilization bag cutting structure provided by the utility model is used, the feeding component 20 is used to realize the automatic and continuous feeding of the sterilization bags to be cut, the cutting component 30 is used to cut the sterilization bags transmitted by the feeding component 20, and the flattening component 40 is used to flatten the incision of the sterilization bag to be cut.

[0031] In order to realize automatic continuous feeding of the sterilization bag to be cut, the feeding assembly 20 includes a pair of wheel groups symmetrically arranged in the horizontal direction, the wheel group includes several pairs of feeding wheels 21, each pair of feeding wheels 21 is symmetrically arranged in the vertical direction, one side of each feeding wheel 21 is coaxially connected to a gear 22, and several gears 22 located on the same horizontal line are meshed with racks 23 on the periphery, and the feeding wheel 21 is driven by a servo motor; the sterilization bag to be cut is placed between the two wheel groups, the servo motor power is turned on, and the servo motor drives the gear coaxially connected to its own output shaft The loading wheel 21 rotates, and the loading wheel 21 drives the gear 22 coaxially connected to itself to rotate. The gear 22 drives the outer rack 23 to rotate, and the rack 23 drives the remaining gears 22 inside itself to rotate. The remaining gears 22 drive the loading wheel 21 coaxially connected to itself to rotate, thereby achieving synchronous rotation of a row of loading wheels 21 at the same horizontal height of the same wheel group. The upper and lower rows of loading wheels 21 of the same wheel group rotate in opposite directions under the drive of the servo motor, thereby driving the sterilization bag between the two rows of loading wheels 21 to move toward the cutting assembly 30.

[0032] Considering the need to cut the sterilization bag transmitted by the loading assembly 20, the cutting assembly 30 includes a pair of slide rails 31 fixedly connected to the two inner side walls of the overhead frame 12, the two slide rails 31 are slidably connected to a slide seat 32 on the side close to each other, a plurality of pulleys 33 are rotatably connected in the slide seat 32, a hot melt knife 34 is fixedly connected between the two slide seats 32, and the pulley 33 is driven by a servo motor; a plurality of guide rods 35 are slidably connected to the edge of the slide seat 32, and a spring 36 is fixedly connected between the bottom of the slide seat 32 and the top of the base 11; the wheel group moves the sterilization bag After being transmitted to the bottom of the hot melt knife 34, the servo motor drives the pulley 33 coaxially connected to its own output shaft to rotate. Under the action of the friction between the pulley 33 and the slide rail 31, the slide 32 moves downward along the slide rail 31, and the two slides 32 drive the preheated hot melt knife 34 to approach the sterilization bag, thereby cutting the sterilization bag. During this period, the spring 36 is compressed. After the cutting is completed, the servo motor drives the pulley 33 to reverse and return to its original position under the action of the restoring force of the spring 36. The cut sterilization bag falls on the conveyor belt 13 and is then transmitted to the next production process.

[0033] In order to flatten the cut of the sterilization bag to be cut, the flattening component 40 includes a compacting arm 41 arranged between the two wheel groups and a support seat 42 fixedly connected to the hot melt knife 34 on the side close to the wheel group, and the support seat 42 is located directly above the edge of the compacting arm 41; due to the characteristics of the sterilization bag material, after being cut by the hot melt knife 34, the cut of the sterilization bag that has not been cut between the wheel groups is prone to wire drawing. The bottom of the compacting arm 41 is close to the top of the support seat 42, thereby flattening the cut of the uncut sterilization bag between the compacting arm 41 and the support seat 42.

[0034] When the automatic sterilization bag cutting structure provided in the utility model is used, the feeding assembly 20 is provided to realize automatic and continuous feeding of the sterilization bags to be cut. Specifically, the sterilization bag to be cut is placed between the two wheel groups, and the servo motor power is turned on. The servo motor drives the feeding wheel 21 coaxially connected to its own output shaft to rotate, and the feeding wheel 21 drives the gear 22 coaxially connected to itself to rotate. The gear 22 drives the outer rack 23 to rotate, and the rack 23 then drives the remaining gears 22 inside itself to rotate, and the remaining gears 22 drive the feeding wheel 21 coaxially connected to itself to rotate, thereby realizing the synchronous rotation of a row of feeding wheels 21 at the same horizontal height of the same wheel group. The upper and lower rows of feeding wheels 21 of the same wheel group rotate in opposite directions under the drive of the servo motor, thereby driving the sterilization bag between the two rows of feeding wheels 21 to move toward the cutting assembly 30; the cutting assembly 30 is used to cut the sterilization bag transmitted by the feeding assembly 20. Specifically, After the wheel group transfers the sterilization bag to the bottom of the hot melt knife 34, the servo motor drives the pulley 33 coaxially connected to its own output shaft to rotate. Under the action of the friction between the pulley 33 and the slide rail 31, the slide 32 moves downward along the slide rail 31, and the two slides 32 drive the preheated hot melt knife 34 to approach the sterilization bag, thereby cutting the sterilization bag. During this period, the spring 36 is compressed. After the cutting is completed, the servo motor drives the pulley 33 to reverse and return to its original position under the action of the restoring force of the spring 36. The cut sterilization bag falls on the conveyor belt 13 and is then transferred to the next production process; the flattening component 40 is used to flatten the incision of the sterilization bag to be cut. Specifically, due to the characteristics of the material of the sterilization bag, after being cut by the hot melt knife 34, the incision of the sterilization bag that has not been cut between the wheel groups is prone to wire drawing. The bottom of the compacting arm 41 is close to the top of the support seat 42, thereby flattening the incision of the uncut sterilization bag between the compacting arm 41 and the support seat 42.
