Description

Technical Field

[0001] This utility model relates to the technical field of food packaging bag slitting machines, specifically a food packaging bag slitting machine. Background Technology

[0002] In the current booming food industry, food packaging is an important link in ensuring food quality and safety and enhancing product appeal. Market demand for it continues to rise. The production efficiency and quality of food packaging bags directly affect the cost and competitiveness of food companies. In the production process of food packaging bags, slitting machines are usually used to cut the food packaging bags.

[0003] There are many types of food packaging bag slitting machines. For example, there are machines that cut easy-tear lines between adjacent food packaging bags. These machines use precise control of the serrated blade cutting device to cut even and neat easy-tear lines between adjacent food packaging bags, making it easier for workers to quickly and conveniently separate individual packaging bags from rolls or stacks of packaging bags, thus improving packaging efficiency.

[0004] Currently, when cutting food packaging bags, a serrated blade cutting device is usually driven to reciprocate, thereby cutting the food packaging bags during the movement. This creates tear lines between adjacent food packaging bags, allowing workers to quickly separate smaller food packaging bags from rolls for use.

[0005] However, during the process of cutting food packaging bags, the serrated blade cutting device generates some impurities that cannot be effectively cleaned, which can easily reduce the cutting quality. Utility Model Content

[0006] Based on this, the purpose of this utility model is to provide a food packaging bag slitting machine to solve the technical problem that some impurities are generated during the slitting process of food packaging bags by the serrated blade cutting device, and these impurities cannot be effectively cleaned, which easily reduces the slitting quality.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a food packaging bag slitting machine, comprising a frame, a fixed block fixedly connected to the top of the frame, a slider slidably connected to the bottom of the fixed block, a serrated cutting device installed at the bottom of the slider, connecting blocks movably connected to both sides of the slider, a roller rotatably connected to each connecting block via a rotating shaft, and an adhesive layer provided on the surface of the roller, a cleaning frame fitted with the fixed block provided on one side of the frame, a filter plate fixedly connected to the cleaning frame, a plurality of brushes fitted with the rollers fixedly connected to the top of the filter plate, a slot provided on one side of the cleaning frame, and a rack provided at the bottom of the slot, and a gear fitted with the rack provided on the surface of each rotating shaft.

[0008] By adopting the above technical solution, when cutting food packaging bags, the slider can be driven to move the serrated blade cutting device back and forth, thereby cutting the food packaging bags during the conveying process. This creates easy-tear lines at the cuts between adjacent food packaging bags without directly cutting them apart. Simultaneously, as the serrated blade cutting device moves, the rollers near the slider's direction of movement press against the food packaging bags, increasing the stability of the cutting. The rollers away from the slider's direction of movement roll on the cut surface, allowing the adhesive layer on the roller surface to help with the cutting. The adhesive layer on the rollers on both sides of the slider adheres to the impurities generated during the cutting process, preventing them from affecting the cutting quality. Therefore, when the serrated blade cutting device reciprocates in a linear motion, the impurities generated during the cutting process can be adhered to the rollers on both sides of the slider and their surface adhesive layer. When the rollers after adhesion are completed enter the cleaning frame, the gears can enter the slots and engage with the rack, thereby achieving rotation within the cleaning frame during the movement of the rollers. This allows the brush to clean the surface of the rollers from all directions, removing the impurities adhering to the adhesive layer and ensuring that the adhesive layer of the rollers always maintains a good adhesion effect, which is conducive to improving the cutting quality.

[0009] The present invention is further configured such that the bottom of the fixing block is provided with a sliding groove, a slider that fits into the sliding groove is slidably connected in the sliding groove, and the slider is configured with a "T" shaped structure. A lead screw that fits into the slider is rotatably connected in the sliding groove, and the slider moves on the surface of the lead screw. A second motor that fits into the lead screw is installed at one end of the fixing block, and the output end of the second motor is connected to one end of the lead screw.

[0010] By adopting the above technical solution, the second motor is started to drive the lead screw to rotate, which in turn drives the slider to move in the groove. This allows for precise control of the slider's speed and position, thus enabling control of the serrated blade cutting device's position and facilitating better cutting of food packaging bags.

[0011] The present invention is further configured such that a storage shaft is rotatably connected inside the frame, a support plate is fixedly connected to one side of the frame, a first motor that matches the storage shaft is installed on the top of the support plate, and the output end of the first motor is connected to one end of the storage shaft.

[0012] By adopting the above technical solution, after tear lines are cut between adjacent food packaging bags, the first motor can be started to drive the storage shaft to rotate, thereby realizing the storage of the cut food packaging bags through the storage shaft.

[0013] The present invention is further provided that a set of rollers are rotatably connected inside the frame.

[0014] By adopting the above technical solution, the rollers can ensure the flatness of the food packaging bag during movement, avoiding wrinkles that may affect cutting.

[0015] The present invention is further configured such that a serrated cutting device is mounted on the bottom of the slider by a first bolt.

[0016] By adopting the above technical solution, the first bolt is used to install the serrated blade cutting device, which facilitates the disassembly and replacement of the serrated blade cutting device. Therefore, when the blade of the serrated blade is worn, it can be quickly replaced, thereby ensuring the cutting effect.

[0017] The present invention is further configured such that connecting blocks are installed on both sides of the slider by means of second bolts.

[0018] By adopting the above technical solution and using the second bolt to install the connecting block, the connection between the connecting block and the slider can be made firm and reliable. At the same time, after the roller has been used for a long time and the adhesive layer on its surface is insufficient, it can be disassembled and replaced, so that the adhesive layer on the roller surface can adhere to impurities in the food packaging bag cutting process.

[0019] The present invention is further configured such that the filter plate is configured as an inclined structure.

[0020] By adopting the above technical solution, the inclined structure of the filter plate allows the cleaned debris to fall off along the inclined structure and through the holes in the filter plate, preventing the cleaned debris from entering the frame and thus affecting the cutting of food packaging bags.

[0021] In summary, the present invention has the following main advantages:

[0022] This invention utilizes a second motor to rotate a lead screw, which in turn moves a slider and a serrated cutting device, facilitating the slitting of food packaging bags. During the movement of the serrated cutting device, the rollers near the slider's direction of movement press against the food packaging bags, increasing slitting stability. Meanwhile, the rollers away from the slider's direction of movement roll on the cut surface, allowing the adhesive layer on their surface to adhere to impurities generated during slitting, preventing them from affecting cutting quality. Therefore, when the serrated cutting device reciprocates linearly, the rollers on both sides of the slider and their adhesive layer adhere to impurities generated during slitting. After adhesion, when the rollers enter the cleaning frame, the gears engage with the rack in the slots, allowing the rollers to rotate within the cleaning frame during movement. This enables the brush to thoroughly clean the roller surface, removing impurities adhering to the adhesive layer and ensuring the adhesive layer maintains good adhesion, thus improving slitting quality.

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] A food packaging bag slitting machine, such as Figure 1-4As shown, the device includes a frame 1, within which a set of rollers 2 are rotatably connected to ensure the flatness of the food packaging bag during movement. A storage shaft 3 is also rotatably connected within the frame 1. A support plate 5 is fixedly connected to one side of the frame 1. A first motor 4, which engages with the storage shaft 3, is mounted on the top of the support plate 5. The output end of the first motor 4 is connected to one end of the storage shaft 3. Therefore, when cutting the food packaging bag with tear lines, the first motor 4 can be activated to drive the storage shaft 3 to rotate. The rotation of the storage shaft 3 allows for the storage of the cut food packaging bag, thus improving the efficiency of food packaging bag cutting.

[0031] Subsequently, a fixing block 6 is fixedly connected to the top of the frame 1, and a slider 8 is slidably connected to the bottom of the fixing block 6. A serrated blade cutting device 12 is installed at the bottom of the slider 8. Connecting blocks 13 are movably connected to both sides of the slider 8. Each connecting block 13 is rotatably connected to a roller 16 via a rotating shaft 15. Therefore, when the slider 8 slides, it can synchronously drive the serrated blade cutting device 12 and the roller 16 to move, thereby realizing the adjustment of the serrated blade cutting device 12. The surface of the roller 16 is provided with an adhesive layer 23. When the serrated blade cutting device 12... During the movement, the roller 16 at the end closest to the slider 8 in the direction of movement presses down on the food packaging bag, which increases the stability of the cutting. Meanwhile, the roller 16 at the end furthest from the slider 8 rolls on the cut surface, allowing the adhesive layer 23 on its surface to adhere to impurities generated during cutting, preventing them from affecting the cutting quality. Therefore, when the serrated blade cutting device 12 reciprocates in a linear motion, the rollers 16 on both sides of the slider 8 and their adhesive layer 23 enhance the stability of the cutting process and ensure proper cutting. To prevent the adhesion of impurities, a cleaning frame 18 is provided on one side of the frame 1, which fits into the fixing block 6. A filter plate 19 is fixedly connected inside the cleaning frame 18. Several brushes 20 that fit into the rollers 16 are fixedly connected to the top of the filter plate 19. A slot 21 is provided on one side of the cleaning frame 18, and a rack 22 is provided at the bottom of the slot 21. Each rotating shaft 15 has a gear 17 that fits into the rack 22. Therefore, when the rollers 16 move into the cleaning frame 18, the gears 17 can enter the slot 21 and fit into the rack 22. The roller 16 can be moved by the driving force of the slider 8, and then the roller 16 can be rotated by the gear 17 and the rack 22, so that the brush 20 can clean the surface of the roller 16 in all directions, remove the impurities adhering to the adhesive layer 23, and ensure that the adhesive layer 23 of the roller 16 always maintains a good adhesion effect, which is conducive to improving the cutting quality. At the same time, the fixing block 6 is located between a set of rollers 2, which can ensure the flatness of the food packaging bag during the movement of the set of rollers 2, and avoid wrinkles during the movement that affect the cutting.

[0032] A groove 7 is provided at the bottom of the fixed block 6, and a slider 8 that matches the groove 7 is slidably connected in the groove 7, allowing the slider 8 to slide within the groove 7. The slider 8 is designed with a "T" shape to increase the stability of its movement. A lead screw 9 that matches the slider 8 is rotatably connected in the groove 7, and the slider 8 moves on the surface of the lead screw 9. A second motor 10 that matches the lead screw 9 is installed at one end of the fixed block 6, and the output end of the second motor 10 is connected to one end of the lead screw 9. When the second motor 10 is started, it drives the lead screw 9 to rotate, thereby driving the slider 8 to move within the groove 7. Thus, the movement of the slider 8 can drive the serrated blade cutting device 12 to move, achieving precise control of the movement position of the serrated blade cutting device 12, thereby enabling better cutting of food packaging bags.

[0033] Furthermore, a serrated blade cutting device 12 is installed at the bottom of the slider 8 via a first bolt 11, which increases the firmness of the connection between the slider 8 and the serrated blade cutting device 12, making it easy to disassemble and replace the serrated blade cutting device 12. Therefore, when the blade of the serrated blade is worn, it can be quickly replaced to ensure the cutting effect. Connecting blocks 13 are installed on both sides of the slider 8 via second bolts 14, which makes the connection between the slider 8 and the connecting blocks 13 firm and reliable. Therefore, when the adhesive layer 23 on the surface of the roller 16 becomes non-adhesive after long-term use, the quick connecting blocks 13 and the roller 16 can be disassembled and replaced to avoid affecting the adhesion of impurities generated during the food packaging bag cutting process. At the same time, the filter plate 19 is set as a sloping structure, which allows the impurities cleaned by the brush 20 to fall into the cleaning frame 18 along the sloping structure and the holes on the surface of the filter plate 19, making it easy to collect and clean the cleaned impurities later. It also prevents the cleaned impurities from entering the frame 1 and affecting the cutting of food packaging bags.
