Description

Technical Field

[0001] This utility model relates to a non-woven packaging transfer, segmentation, connection, and buffer device, belonging to the category of packaging equipment. Background Technology

[0002] Non-woven fabrics are characterized by good sealing properties, yet breathability and high structural strength. They are commonly used in the production of hygiene products, but with increased production and decreased prices, their application in packaging bags has gradually expanded in recent years.

[0003] This is especially true for packaging materials that require both airtightness and high structural strength, while also being breathable, such as flour packaging.

[0004] Non-woven fabrics used in packaging employ a folded structure, with the product name and graphic information printed on their surface.

[0005] Non-woven fabrics are not elastic and their seams are heat-sealed.

[0006] Currently, the printing press cannot be interrupted, otherwise printing discontinuity will occur. Rewinding after printing can result in loose non-woven fabric and inaccurate heat sealing and cutting. Therefore, heat sealing and cutting are performed directly after printing. This stage requires feeding non-woven fabric after printing to continue until heat sealing and cutting. A buffer device is needed to buffer and dry the printed material after printing before heat sealing and cutting. Summary of the Invention

[0007] To address the aforementioned problems, this utility model provides a non-woven packaging transfer printing segmentation and connection buffer device, which solves the problem of buffering the non-woven packaging after printing to the heat sealing and air cutting device.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] This utility model relates to a non-woven fabric packaging transfer printing segmentation and buffer device, comprising a frame, a swing frame, a buffer, multiple sets of fixed rollers, and multiple sets of buffer rollers. The frame is rectangular, with open front, rear, and top sections. The front section, the material inlet, is configured as a printing machine, and the rear section, the material feeding end, is configured as a bag stacking machine. There are at least two sets of fixed rollers, located on the upper part of the frame, with both ends of the fixed rollers mounted on the frame. The swing frame is located inside the frame, with one end hinged to the frame and the other end mounted on the buffer roller. The buffer roller is mounted on the swing frame, and a buffer is provided between the swing frame and the frame. One end of the buffer is connected to the swing frame, and the other end is connected to the frame. The buffer drives the swing frame to move downwards. The non-woven fabric material is turned from the fixed rollers in the material inlet direction to the buffer rollers, then from the buffer rollers to the fixed rollers in the other material feeding direction, and finally from the fixed rollers in the material feeding direction to the bag stacking machine.

[0010] According to the nonwoven packaging transfer dividing and connecting buffer device, there are four sets of fixed rollers and three sets of buffer rollers. The nonwoven fabric reciprocates in sequence through the fixed rollers, buffer rollers, and fixed rollers. The swing frame is a rectangular frame with a hinge structure on one long side inside the frame.

[0011] According to the aforementioned non-woven fabric packaging transfer dividing and connecting buffer device, the buffer roller includes a rotating part and a buffer shaft, with a bearing mechanism between them. Both ends of the buffer shaft are fixed to a swing frame. The fixed roller includes a central fixed shaft and an outer roller part, with a bearing structure between them. Both ends of the fixed shaft are fixed to the swing frame.

[0012] According to the non-woven packaging transfer dividing and connecting buffer device, the buffer is a cylinder. The cylinder body end is hinged to the lower part of the swing frame hinge position of the machine frame, and the piston rod end of the cylinder is hinged to the middle position of the swing frame. The cylinders are arranged in two sets on both sides of the swing frame.

[0013] According to the nonwoven packaging transfer dividing and connecting buffer device, the frame is provided with an elevated frame in the material feeding direction. The top and middle of the elevated frame are respectively provided with a high-position reversing roller and a low-position steering roller. The low-position reversing roller is higher than the fixed roller, and the low-position steering roller and the fixed roller are arranged in a staggered manner.

[0014] According to the non-woven packaging transfer dividing and connecting buffer device, the frame is made of rectangular tube, with rectangular sides and rectangular front and back directions. The top of the frame is fixedly connected to the top of the printing machine at the front end, and the rear end of the frame is fixedly connected to the bag stacking machine.

[0015] According to the non-woven packaging transfer dividing and connecting buffer device, the buffer is a spring, one end of the spring is fixed to the frame and the other end is fixed to the swing frame, and the spring drives the swing frame to move downward.

[0016] The advantages of this utility model are:

[0017] This device connects the printing and folding heat sealing processes in the production of non-woven paper bags. It can buffer the continuous printing process and feed the material to the folding heat sealing equipment, thus enabling uninterrupted production of non-woven fabrics.

[0018] The buffer structure of this device will buffer the continuous feeding and form intermittent discharge, which is beneficial to the air drying of non-woven fabric after printing and reduces the use of equipment. Attached Figure Description

[0024] The present invention will now be further described in detail:

[0025] This utility model relates to a non-woven fabric packaging transfer printing and separating buffer device, comprising a frame 1, a swing frame 2, a buffer 3, multiple sets of fixed rollers 5, and multiple sets of buffer rollers 6. The multiple sets of fixed rollers 5 and multiple sets of buffer rollers 6 are mounted on the swing frame, which is connected to the frame via the buffer. The buffer is a reciprocating and extendable structure. The non-woven fabric is reciprocated and wound between the fixed rollers and the buffer rollers. By varying the distance between the fixed rollers and the buffer rollers, stable and continuous feeding is achieved, while intermittent periodic feeding is performed, to facilitate heat sealing and cutting of the folded non-woven fabric.

[0026] Specifically, the frame 1 is rectangular, with open front, rear, and top sections. The front end, the material receiving end, is equipped with a printing machine 9, and the rear end, the material feeding end, is equipped with a bag stacking machine 8. At least two sets of fixed rollers 5 are positioned on the upper part of the frame 1, with both ends of the fixed rollers 5 mounted on the frame 1. The swing frame 2 is located inside the frame 1, with one end hinged to the frame 1 and the other end equipped with a buffer roller 6. The buffer roller 6 is mounted on the swing frame 2, and a buffer is provided between the swing frame 2 and the frame 1. One end of the buffer is connected to the swing frame 2, and the other end is connected to the frame 1. The buffer 3 drives the swing frame 2 downwards. The nonwoven fabric 7 material is redirected from the fixed roller 5 in the material receiving direction to the buffer roller 6, then from the buffer roller 6 to the fixed roller 5 in the other material feeding direction, and finally to the bag stacking machine 8. The swing frame, driven downwards by the buffer, pulls the buffer roller downwards, stretching the nonwoven fabric.

[0027] When the bag-stacking machine feeds the nonwoven fabric, it pulls the nonwoven fabric upwards, causing the swing frame and buffer rollers to swing upwards, rapidly drawing the nonwoven fabric in. Then, the bag-stacking machine stops feeding, and the nonwoven fabric, pulled downwards by the swing frame and buffer rollers, waits for the machine's feeding drive to restart. At this point, the nonwoven fabric is rapidly pulled in again, and the swing frame swings upwards. These steps are repeated, achieving buffered feeding of the nonwoven fabric.

[0028] Specifically, in this device, there are four sets of fixed rollers 5 and three sets of buffer rollers 6. The nonwoven fabric 7 reciprocates sequentially between the fixed rollers 5, buffer rollers 6, and fixed rollers 5. The swing frame 2 is a rectangular frame with a hinge structure on one long side, located inside the frame 1. The surfaces of the rolling rollers and buffer rollers in this device are provided with anti-slip textures.

[0029] The buffer roller 6 of this device includes a rotating part and a buffer shaft, with a bearing mechanism between them. Both ends of the buffer shaft are fixed to the swing frame 2. The fixed roller 5 includes a central fixed shaft and an outer roller part, with a bearing structure between them. Both ends of the fixed shaft are fixed to the swing frame 2.

[0030] The buffer 3 of this device is a cylinder. The cylinder body end is hinged to the lower part of the swing frame 2 of the frame 1, and the piston rod end is hinged to the middle position of the swing frame 2. The cylinders are arranged in two sets on both sides of the swing frame 2.

[0031] The frame 1 is equipped with an overhead frame in the material feeding direction. The top and middle of the overhead frame are respectively equipped with a high-position reversing roller and a low-position steering roller 10. The low-position reversing roller is higher than the fixed roller 5. The low-position steering roller 10 and the fixed roller 5 are arranged in a staggered manner.

[0032] The frame 1 is made of rectangular tube, and is rectangular in both front and back directions. The top of the frame is fixedly connected to the top of the printing machine 9 at the front end, and the rear end of the frame 1 is fixedly connected to the bag stacking machine 8.

[0033] In another embodiment of this utility model, the buffer 3 is a spring, one end of which is fixed to the frame 1 and the other end is fixed to the swing frame 2. The spring drives the swing frame 2 to move downward.

[0034] This device connects the printing and folding heat sealing processes in the production of non-woven paper bags. It can buffer the continuous printing process and feed the material to the folding heat sealing equipment, thus enabling uninterrupted production of non-woven fabrics.

[0035] The buffer structure of this device will buffer the continuous feeding and form intermittent discharge, which is beneficial to the air drying of non-woven fabric after printing and reduces the use of equipment.
