Description

Technical Field

[0001] This utility model relates to the field of easy-tear line processing technology, and in particular to an easy-tear line processing device for hygiene product packaging bags. Background Technology

[0002] Packaging bags with easy-tear lines on the market typically achieve this through vertical pre-cutting. However, in practice, this vertical pre-cutting process is problematic because the vertical movement of the serrated blade needs to maintain a relatively high speed. Furthermore, it is affected by the hardness and thickness of the material being pre-cut, making it easy for the blade to cut too shallowly and resulting in incomplete pre-cutting, thus failing to achieve the desired easy-tear line.

[0003] Existing technology CN218640442U discloses a device for processing easy-tear lines on sanitary product packaging bags, including a mounting frame. A first guide roller and a second guide roller are rotatably mounted on the mounting frame. A saw blade assembly is slidably mounted on the mounting frame. The mounting frame is equipped with a drive mechanism for driving the saw blade assembly to move back and forth. A clamping mechanism located on the right side of the saw blade assembly is also provided on the mounting frame for clamping the packaging bag. A fixing plate is bolted to the mounting frame, and a slide rail is fixedly connected to the fixing plate. The saw blade assembly includes a slide block, a first mounting plate, a second mounting plate, a third mounting plate, and a saw blade. The slide block is mounted on the slide rail, the first mounting plate is fixedly connected to the slide block, the second mounting plate is fixedly connected to the rear side of the first mounting plate, and the third mounting plate is fixedly connected to the lower side of the second mounting plate. The saw blade is rotatably mounted on the rear side of the third mounting plate via bearings. Compared to existing technologies, this invention has better stability and higher production efficiency.

[0004] However, in the aforementioned technologies, the packaging bags may be affected by various factors during processing, such as uneven conveyor belt speed, insufficient installation accuracy of guide rollers, and uneven tension of the packaging bags themselves, which can lead to bag deviation. Limiting components can constrain the movement of the packaging bags, reducing deviation and ensuring that the bags move along a predetermined path, thus smoothly completing the processing of the easy-tear lines. Utility Model Content

[0005] The purpose of this utility model is to provide a device for processing easy-tear lines on hygiene product packaging bags, which solves the problem that packaging bags may be affected by various factors during the processing of existing technology, such as uneven conveyor belt speed, insufficient installation accuracy of guide rollers, and uneven tension of the packaging bag itself, thus causing the packaging bag to deviate.

[0006] To achieve the above objectives, this utility model provides a device for processing easy-tear lines on sanitary product packaging bags, including a mounting frame, a first guide roller, a second guide roller, a saw blade assembly, and a pressing mechanism. The first guide roller and the second guide roller located to the right of the first guide roller are rotatably mounted on the mounting frame. The saw blade assembly, which moves in the front-back direction, is slidably mounted on the mounting frame. The pressing mechanism located to the right of the saw blade assembly is provided on the mounting frame.

[0007] It also includes adjustable limit components;

[0008] The adjusting and limiting assembly includes a first limiting plate, a connecting ring, a rotating ring, a connecting rod, a second limiting component, and an adjusting and rotating component. The first limiting plate is sleeved on the outside of the first guide roller. The connecting ring is rotatably connected to the first limiting plate and is located in the groove of the first limiting plate. The rotating ring is fixedly connected to the connecting ring and is located on the inner ring wall of the connecting ring. One end of the connecting rod is fixedly connected to the first limiting plate, and the other end of the connecting rod is fixedly connected to the second limiting component. The second limiting component is disposed on the second guide roller. The adjusting and rotating component is connected to the first limiting plate and passes through the mounting frame.

[0009] The second limiting component includes a second limiting plate and a limiting rod. The second limiting plate is sleeved on the outside of the second guide roller. The limiting rod is fixedly connected to the second limiting plate and passes through the mounting frame near one end of the second guide roller.

[0010] The mounting frame has a limiting hole, which is located at one end of the mounting frame near the second guide roller and cooperates with the limiting rod.

[0011] The mounting bracket also has a threaded hole, which is located at one end of the mounting bracket near the first guide roller and extends through the mounting bracket.

[0012] The adjusting rotating component includes an adjusting screw and a rotating handle. One end of the adjusting screw passes through the threaded hole and is rotatably connected to the upper end of the first limiting plate via a bearing. The rotating handle is fixedly connected to the adjusting screw and is located at the other end of the adjusting screw.

[0013] This utility model discloses a device for processing easy-tear lines on sanitary product packaging bags. The first limiting plate is driven to move by the adjusting rotating component, and the first limiting plate drives the second limiting plate to move synchronously through the connecting rod.

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] This utility model discloses a device for processing easy-tear lines on sanitary product packaging bags: It includes a mounting frame 101, a first guide roller 102, a second guide roller 103, a saw blade assembly 104, a pressing mechanism 105, and an adjusting and limiting assembly. The adjusting and limiting assembly includes a first limiting plate 106, a connecting ring 107, a rotating ring 108, a connecting rod 109, a second limiting component, and an adjusting and rotating component. The second limiting component includes a second limiting plate 110 and a limiting rod 111. The mounting frame 101 has a limiting hole 112 and a threaded hole 113. The adjusting and rotating component includes an adjusting screw 114 and a rotating handle 115. This solution addresses the problem in existing technologies where packaging bags may be affected by various factors during processing, such as uneven conveyor belt speed, insufficient installation accuracy of the guide rollers, and uneven tension of the packaging bag itself, leading to bag deviation. It is understood that the aforementioned solution can adjust the guiding width of the first guide roller 102 and the second guide roller 103 based on the width of the packaging bag through the adjusting and limiting assembly, thereby preventing bag deviation.

[0022] In this embodiment, the first guide roller 102 and the second guide roller 103 located to the right of the first guide roller 102 are rotatably mounted on the mounting frame 101. The saw blade assembly 104, which moves in the front-back direction, is slidably mounted on the mounting frame 101. The clamping mechanism 105 located to the right of the saw blade assembly 104 is provided on the mounting frame 101. The first guide roller 102 and the second guide roller 103 are rotatably mounted on the mounting frame 101. The saw blade assembly 104 is slidably mounted on the mounting frame 101. The mounting frame 101 is provided with a drive mechanism for driving the saw blade assembly 104 to move back and forth. The mounting frame 101 is provided with a pressing mechanism 105 located on the right side of the saw blade assembly 104 for pressing the packaging bag. A fixing plate is fixedly connected to the mounting frame 101 by bolts. A slide rail is fixedly connected to the fixing plate. The saw blade assembly 104 includes a slide block, a first mounting plate, a second mounting plate, a third mounting plate, and a saw blade. The slide block is mounted on the slide rail. The first mounting plate is fixedly connected to the slide block. The second mounting plate is fixedly connected to the rear side of the first mounting plate. The third mounting plate is fixedly connected to the lower side of the second mounting plate. The saw blade is rotatably mounted on the rear side of the third mounting plate through a bearing. It has good stability and high production efficiency.

[0023] The first limiting plate 106 is sleeved on the outside of the first guide roller 102. The connecting ring 107 is rotatably connected to the first limiting plate 106 and is located in the groove of the first limiting plate 106. The rotating ring 108 is fixedly connected to the connecting ring 107 and is located on the inner ring wall of the connecting ring 107. One end of the connecting rod 109 is fixedly connected to the first limiting plate 106, and the other end of the connecting rod 109 is fixedly connected to the second limiting member. The second limiting member is disposed on the second guide roller 103. The adjusting rotating member is connected to the first limiting plate 106 and passes through the mounting frame 101. The first limiting plate 106 is a cube with a circular through hole in the middle and an open groove inside the through hole. The structure of the groove matches the structure of the connecting ring 107. The inner wall of the connecting ring 107 is fixed with the rotating ring 108. The inner diameter of the rotating ring 108 matches the diameter of the first guide roller 102. The rotating ring 108 rotates with the first guide roller 102 through the connecting ring 107 to reduce friction on the packaging bag. The first limiting plate 106 is convex in shape. One of its upper ends is connected to the adjusting rotating component. The adjusting rotating component drives the first limiting plate 106 to move horizontally along the first guide roller 102. The top of the first limiting plate 106 is also fixedly connected to one end of the connecting rod 109. The other end of the connecting rod 109 is fixedly connected to the second limiting component. The second limiting component moves synchronously through the connecting rod 109. Therefore, by driving the first limiting plate 106 to move through the adjusting rotating component, the first limiting plate 106 synchronously drives the second limiting plate 110 to move through the connecting rod 109, thereby realizing the simultaneous adjustment of the guiding width of the first guide roller 102 and the second guide roller 103.

[0024] Secondly, the second limiting plate 110 is sleeved on the outside of the second guide roller 103; the limiting rod 111 is fixedly connected to the second limiting plate 110 and passes through the end of the mounting frame 101 near the second guide roller 103; the limiting hole 112 is provided at the end of the mounting frame 101 near the second guide roller 103 and cooperates with the limiting rod 111. The second limiting plate 110 has the same shape and size as the first limiting plate 106. The second limiting plate 110 also has a circular through hole, and a groove matching the connecting ring 107 is opened in the through hole. The connecting ring 107 is also rotatably arranged in the groove of the second limiting plate 110, and the rotating ring 108 is fixedly arranged on the inner ring wall of the connecting ring 107. The rotating ring 108 is sleeved on the second guide roller 103. The packaging bag passing through the second guide roller 103 is limited by the second limiting plate 110, the connecting ring 107 and the rotating ring 108. The limiting rod 111 passes through the limiting hole 112. The limiting rod 111 and the limiting hole 112 cooperate to further restrict the rotation of the fixedly connected second limiting plate 110, so that the second limiting plate 110 can only move horizontally.

[0025] Meanwhile, the threaded hole 113 is located at one end of the mounting frame 101 near the first guide roller 102 and passes through the mounting frame 101; one end of the adjusting screw 114 passes through the threaded hole 113 and is rotatably connected to the upper end of the first limiting plate 106 via a bearing; the handle 115 is fixedly connected to the adjusting screw 114 and is located at the other end of the adjusting screw 114. The thread on the inner side of the threaded hole 113 engages with the thread on the outer side of the adjusting screw 114. The adjusting screw 114 passes through the threaded hole 113 and is rotatably connected to the first limiting plate 106 via a bearing. The adjusting screw 114 extends and retracts on the mounting frame 101 by helical rotation, thereby driving the first limiting plate 106 to move horizontally. Rotating the adjusting screw 114 via the handle 115 requires less effort.

[0026] When using the easy-tear line processing device for sanitary product packaging bags of this utility model, the first limiting plate 106 is driven to move by the adjusting rotating component, and the first limiting plate 106 drives the second limiting plate 110 to move synchronously through the connecting rod 109, thereby realizing the simultaneous adjustment of the guiding width of the first guide roller 102 and the second guide roller 103.

[0027] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
