Description

Technical Field

[0001] This utility model relates to the field of nonwoven bag production technology, and in particular to a nonwoven bag punching device. Background Technology

[0002] In the production process of nonwoven bags, holes need to be processed on the nonwoven bags using a punching device to facilitate the subsequent handle installation process. Existing technology, such as the utility model patent: A punching mechanism for nonwoven bag production that can prevent nonwoven bags from shifting (Publication No.: CN220785066U), discloses a punching mechanism for nonwoven bag production that can prevent nonwoven bags from shifting, including: a base, a punching device connected to the base to optimize the punching capability of the device, and a translation device connected to the punching device to optimize the translation capability of the device. The force is optimized, and a fixing device is connected to the translation device to optimize the fixing ability of the device. This is a punching mechanism for non-woven bag production that can prevent non-woven bags from shifting. The motor drives the rotating shaft to rotate, which can drive the threaded rod A and threaded rod B to rotate simultaneously. Since the threads between threaded rod A and threaded rod B are in opposite directions, the limiting rod will move in opposite directions as the rotating shaft rotates. The rotation of the motor can make the limiting rod move in the front and back direction, so that it can be properly positioned according to non-woven bags of different sizes.

[0003] When punching holes in non-woven bags, the aforementioned punching device lacks a structure to transport the non-woven bag to the bottom of the punching head. Manual assistance is required to place the non-woven bag under the punching head for the operation, thus the punching efficiency needs to be improved.

[0004] To address the aforementioned problems, this utility model provides improvements. Utility Model Content

[0023] The following will refer to the appendix in the embodiments of this utility model. Figure 1-6 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] As shown in the figure, a non-woven bag punching device includes a frame 1, a punching mechanism 2 mounted on the frame 1, and a feeding mechanism 3 mounted on the frame 1. The feeding mechanism 3 includes a feeding plate 31, a positioning frame 32, and a pressing assembly 33. The feeding plate 31 is horizontally slidably mounted on the frame 1 below the punching mechanism 2. The positioning frame 32 is mounted on the feeding plate 31. A synchronous belt 12, which is driven and connected to a motor mounted on the frame 1, is mounted on the frame 1. The feeding plate 31 is fixedly connected to the synchronous belt 12. The pressing assembly 3... 3 includes a first transmission rod 331, a first pressing rod 332, a second transmission rod 333, and a second pressing rod 334. The first transmission rod 331 and the second transmission rod 333 are respectively rotatably mounted on two symmetrical side plates of the pressing frame, and the first transmission rod 331 and the second transmission rod 333 are respectively hinged to the output shafts of the first pressing cylinder 335 and the second pressing cylinder 336 mounted on the feeding plate 31. A plurality of L-shaped first pressing rods 332 and second pressing rods 334 are respectively fixedly connected to the first transmission rod 331 and the second transmission rod 333.

[0025] Specifically, the punching mechanism 2 includes a punching head 21, a positioning seat 22, a drive rod 23, and a punching cylinder 24. The positioning seat 22 is fixedly mounted on the frame 1. The drive rod 23 is slidably mounted on the positioning seat 22. The punching head 21 is fixedly connected to the lower end of the drive rod 23. The punching cylinder 24 is mounted on the frame 1, and the output shaft of the punching cylinder 24 is fixedly connected to the upper end of the drive rod 23 with its downward facing direction. The feeding plate 31 has a waste discharge hole 311 that matches the punching head 21.

[0026] In the above structure, the motor is connected to the synchronous belt 12 via a synchronous pulley. The motor drives the synchronous belt 12 to move, and the synchronous belt 12 drives the feeding plate 31 to slide horizontally on the frame 1. When punching holes in the non-woven bag, the non-woven bag is placed into the positioning frame 32, which has an inner hole matching the outer contour of the non-woven bag, and placed on the feeding plate 31. The positioning frame 32 ensures the accurate positioning of the non-woven bag. Then, the first pressing cylinder 335 and the second pressing cylinder 336 drive the first transmission rod 331 and the second transmission rod 333 to rotate, respectively. The first transmission rod 331 and the second transmission rod 333 drive the first pressing rod 332 and the second pressing rod 334 to swing, so that the ends of the first pressing rod 332 and the second pressing rod 334 swing towards the non-woven bag placed in the positioning frame 32 and press against the non-woven bag, thus punching the non-woven bag. The bag is pressed onto the feeding plate 31. Then, the motor drives the synchronous belt 12 to move the feeding plate 31 downwards towards the punching mechanism, thus moving the non-woven bag pressed onto the feeding plate 31 to the position where the waste discharge hole 311 is aligned with the punching head 21. Next, the punching cylinder 24 drives the drive rod 23 to move downwards on the positioning seat 22, thereby driving the punching head 21 to punch holes in the non-woven bag, completing the punching operation of the non-woven bag. The punched waste material falls through the waste discharge port. In the above structure and process, the non-woven bag is positioned accurately by the positioning frame 32, and the pressing component 33 ensures that the non-woven bag does not shift during punching, thus ensuring the accuracy of punching. Furthermore, the punching operation of the non-woven bag can be automatically completed simply by manually placing the non-woven bag into the positioning frame 32, thereby saving manpower and improving production efficiency.

[0027] Furthermore, based on the above structure, the ends of the first pressure rod 332 and the second pressure rod 334 are respectively connected to a first anti-slip pad 337 and a second anti-slip pad 338 made of flexible material. When the first pressure rod 332 and the second pressure rod 334 press the non-woven bag, the first anti-slip pad 337 and the second anti-slip pad 338 come into contact with the non-woven bag, increasing the friction between the first pressure rod 332 and the second pressure rod 334 and the non-woven bag, thereby strengthening the stability of pressing the non-woven bag on the feeding plate 31, ensuring that the non-woven bag will not shift during punching. Moreover, by changing the first anti-slip pad 337 and the second anti-slip pad 338 of different thicknesses, the pressing of non-woven bags of different thicknesses can be achieved, which has better applicability.

[0028] Furthermore, based on the above structure, the feeding plate 31 is composed of a movable frame 312 and a swing plate 313. The movable frame 312 has an inner hole that matches the positioning frame 32. The positioning frame 32 is fixedly mounted on the movable frame 312 so that their inner holes are aligned. The movable frame 312 passes through two support rods 11 mounted on the frame 1 and is fixedly connected to the synchronous belt 12. The swing plate 313 is disposed inside the movable frame 312, and one end of the swing plate 313 is rotatably connected to the movable frame 312. The movable frame 312 is provided with a rotary cylinder 34 that is drively connected to the rotation shaft of the swing plate 313. The waste discharge hole 311 is disposed on the swing plate 313, and the rotary cylinder 34 can drive the swing plate. The feed plate 31 is swaying on the moving frame 312. The moving frame 312 is connected to the support rod 11 to achieve the sliding setting of the feed plate 31 on the frame 1. When punching holes in the non-woven bags, the rotary cylinder 34 drives the swing plate 313 to swing to a horizontal position within the moving frame 312. The non-woven bags placed in the positioning frame 32 are placed on the swing plate 313. After the punching operation of the non-woven bags is completed, the rotary cylinder 34 drives the swing plate 313 to swing, causing the swing plate 313 to tilt. The non-woven bags that have been punched on the swing plate 313 can then slide down the tilted swing plate 313 and leave the feed plate 31, automatically realizing the unloading after punching, thereby further saving manpower and improving production efficiency.

[0029] Furthermore, based on the above structure, the free end of the swing plate 313 forms an abutment portion 314. When the swing plate 313 is located within the moving frame 312, the abutment portion 314 abuts against the moving frame 312. A J-shaped clamping rod 315 is rotatably connected to the moving frame 312. A transmission swing arm 316 is fixedly connected to the second transmission rod 333. The end of the transmission swing arm 316 is hinged to the upper end of the clamping rod 315. When the rotary cylinder 34 drives the swing plate 313 to swing to a horizontal position within the moving frame 312, the abutment portion 314 abuts against the moving frame 312. At the same time, while the second transmission rod 333 drives the second pressing rod 334 to swing towards the non-woven bag placed on the swing plate 313 to press the non-woven bag, the second transmission rod 333 drives the transmission swing arm 316 to swing, thereby driving the clamping rod 315 towards the abutment portion 314. When the second pressing rod 334 presses against the nonwoven bag, the clamping rod 315 presses against the abutment part 314, pressing the abutment part 314 against the moving frame 312. Through the action of the clamping rod 315, the swing of the swing plate 313 is limited, ensuring the stability of the swing plate 313 when it is in a horizontal position. This ensures the accuracy of the position of the nonwoven bag when it is placed on the swing plate 313 and its stability when it is pressed, thereby ensuring the accuracy of the punching. Similarly, the end of the clamping rod 315 is provided with a third anti-slip pad 317 to enhance the stability of the pressing abutment part 314. After the punching operation is completed, the second pressing rod 334 moves away from the nonwoven bag and resets, while the clamping rod 315 moves away from the abutment part 314 and resets. At this time, the rotary cylinder 34 can drive the swing plate 313 to swing to feed the nonwoven bag.

[0030] In addition, based on the above structure, a feeding guide plate 4 is inclinedly arranged on the frame 1 below the moving path of the feeding plate 31. The inclination direction of the feeding guide plate 4 is the same as the swing direction of the swing plate 313. When the rotary cylinder 34 drives the swing plate 313 to feed the non-woven bags, the non-woven bags that slide down the swing plate 313 fall onto the feeding guide plate 4 and slide out of the frame 1 along the feeding guide plate 4, which facilitates the collection of the perforated non-woven bags.

[0031] Furthermore, based on the above structure, a waste discharge guide plate 5 is inclinedly arranged on the free end of the swing plate 313, located below the waste discharge hole 311. The inclination direction of the waste discharge guide plate 5 is opposite to that of the feeding guide plate 4. The waste generated during the punching of the non-woven bag falls through the waste discharge hole 311 and onto the waste discharge guide plate 5, sliding down along the waste discharge guide plate 5. Since the inclination direction of the waste discharge guide plate 5 is opposite to that of the feeding guide plate 4, the waste slides away from the feeding guide plate 4 and does not fall onto the feeding guide plate 4, thus avoiding affecting the collection of the punched non-woven bag.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
