Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to a bag-loading mechanism suitable for PE packaging bags. Background Technology

[0002] In the modern packaging industry, polyethylene (PE) material has gradually become an ideal choice for packaging various products due to its excellent flexibility, water resistance, and recyclability. Especially in the food, daily necessities, and cosmetics industries, PE material is increasingly favored by businesses and consumers for its lightweight and safety. However, the physical properties of flexible single-layer PE bags determine their instability during the bag-feeding process: this material is prone to deformation and slippage under stress, and due to its flexibility, traditional bag-feeding mechanisms often cannot effectively grasp and guide it into the production line. This not only increases the equipment failure rate but also leads to production line downtime, thus affecting overall production efficiency. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bag-loading mechanism suitable for PE packaging bags, ensuring that stacked PE bags can be smoothly transported one by one to the next process, avoiding deformation and slippage, reducing equipment failure rate, and improving production efficiency.

[0004] The technical solution to achieve the purpose of this utility model is:

[0005] A bag-loading mechanism for PE packaging bags includes a frame, a movable bag storage section, a lifting bag suction section, a horizontal bag clamping section, a bag limiting section, and a servo bag conveying section mounted on the frame. The movable bag storage section and the bag limiting section are arranged adjacent to each other. The lifting bag suction section is located above the end of the movable bag storage section near the bag limiting section. The horizontal bag clamping section is located above the bag limiting section with its clamping opening facing the lifting bag suction section, and is used to transfer the PE bags suctioned by the lifting bag suction section to the bag limiting section. The servo bag conveying section includes a conveying roller located below the bag limiting section, and the conveying roller is adapted to convey the PE bags on the bag limiting section to the next process.

[0006] Furthermore, the movable storage bag unit includes a first support frame fixedly mounted on the side of the frame. A first platform is fixedly mounted on the top of the first support frame, and a plurality of limiting rods are provided at the bottom that are movably arranged in the horizontal direction. A first sliding groove corresponding to the limiting rods is opened on the first platform, and the plurality of limiting rods vertically pass through the first sliding groove to form a limiting surface.

[0007] Furthermore, a first guide rod is fixedly mounted on the bottom of the first support frame, and a connecting rod is slidably provided between the two first guide rods. The limiting rod is vertically fixed on the connecting rod. A first cylinder is fixedly mounted on one end of the first support frame. The piston rod of the first cylinder is horizontally arranged and vertically fixed to the connecting rod.

[0008] Furthermore, a first positioning plate is provided on any side of the first platform that is perpendicular to the limiting surface, and a second positioning plate is provided on the side of the first platform near the bag limiting part.

[0009] Furthermore, the lifting suction bag unit includes a lifting cylinder fixedly mounted on the top of the frame. The piston rod of the lifting cylinder is vertically downward and fixedly connected to a fixing plate. The fixing plate is evenly provided with multiple pneumatic suction cups along its length.

[0010] Furthermore, the translational bag clamping part includes a slide cylinder and a second guide rod fixedly mounted on the top of the frame and arranged in parallel. A moving block fixedly connected to the sliding block of the slide cylinder is slidably mounted on the second guide rod. A crossbar is fixedly suspended on the moving block. Pneumatic clamps are symmetrically provided at both ends of the crossbar. The pneumatic clamps are provided with opposing grippers to form a clamping opening. Anti-slip pads are provided on the inner side of the grippers.

[0011] Furthermore, the bag limiting part includes a second support plate fixedly installed in the middle of the frame, a second platform plate fixedly installed on the top of the second support plate, and multiple parallel second slide grooves opened on the second platform plate, with adjustable spacing limiting posts provided in the second slide grooves.

[0012] Furthermore, a forward and reverse adjusting screw is provided below the second platform and mounted on the second support plate. A third guide rod is provided parallel to both sides of the forward and reverse adjusting screw. The forward thread area and the reverse thread area of ​​the forward and reverse adjusting screw are respectively threaded to the mounting plate that slides with the third guide rod. A second cylinder is fixedly mounted on the mounting plate. The piston rod of the second cylinder passes through the mounting plate and is fixedly connected to a first connecting plate that is parallel to the mounting plate. The limiting post is vertically fixedly mounted on the first connecting plate.

[0013] Furthermore, it also includes a lifting and pressing part, which includes a pressing cylinder fixedly mounted on the top of the frame.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects:

[0016] (1) This utility model first separates the stacked PE bags by lifting and suction bag part, and then transfers the PE bags by translating bag clamping part. On the one hand, it saves time by reducing the range of motion of individual parts. On the other hand, it fully considers the soft and slippery characteristics of PE bag material and adopts clamping transfer instead of direct suction transfer. The PE bag is transported by the movable bag storage part, bag limiting part and servo bag conveying part. The reliability is higher, the long single conveying line is avoided, the deformation and slippage of PE bags are effectively prevented, the equipment failure rate is reduced and the production efficiency is improved.

[0017] (2) This utility model uses a movable limiting rod to push the PE bags stacked on the first platform to move, which can transport multiple PE bags at the same time, and at the same time prevent the PE bags from sliding backward due to inertia by the limiting rod.

[0018] (3) This utility model uses a cylinder to drive the connecting rod to move along the first guide rod, thereby driving the limit rod to move. The structure is simple and the movement is smooth.

[0019] (4) By setting a first positioning plate as a reference surface, this utility model ensures that the front and rear sides of the PE bags stacked on the platform are kept level. Then, under the push of the limiting rod and the action of the second positioning plate, the left and right sides of the PE bags are kept level, thus ensuring the positional accuracy of the PE bag conveying.

[0020] (5) This utility model uses a cylinder to drive the pneumatic suction cup to perform lifting and lowering movements. It has a simple structure, is easy to control, and has a rapid action response.

[0021] (6) This utility model provides further protection by setting anti-slip soft pads to prevent the PE bag from being pinched by the claws.

[0022] (7) This utility model can meet the bag-loading needs of more PE bags by setting adjustable spacing limit posts, thus making it more versatile.

[0023] (8) This utility model uses a forward and reverse adjusting screw to quickly adjust the original spacing of the limiting post, and then uses a cylinder to achieve a secondary adjustment of the spacing of the limiting post, which has a wider range of applications.

[0024] (9) This utility model sets up a lifting and pressing part to press the bag body and prevent the PE bag from shifting during movement.

[0025] (10) By setting up a lifting baffle, the PE bag stops moving after it moves to contact the baffle plate, thus achieving automatic positioning and improving the accuracy of conveying to the next process. Attached Figure Description

Detailed Implementation

[0033] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0034] (Example 1)

[0035] like Figures 1 to 4 The bag feeding mechanism for PE packaging bags shown includes a frame 1, a movable bag storage section 2, a lifting bag suction section 3, a horizontal bag clamping section 4, a bag limiting section 5, and a servo bag conveying section 6, all mounted on the frame 1. The movable bag storage section 2 and the bag limiting section 5 are arranged adjacent to each other. The lifting bag suction section 3 is located above the end of the movable bag storage section 2 that is close to the bag limiting section 5. The horizontal bag clamping section 4 is located above the bag limiting section 5 and its clamping opening is directly opposite the lifting bag suction section 3. It is used to transfer the PE bags suctioned by the lifting bag suction section 3 to the bag limiting section 5. The servo bag conveying section 6 includes a conveying roller 6-1 located below the bag limiting section 5. The conveying roller 6-1 is adapted to convey the PE bags on the bag limiting section 5 to the next process.

[0036] Specifically, the mobile bag storage unit 2 includes a first support frame 2-1 fixed to the side of the frame 1. A first platform 2-2 is fixed to the top of the first support frame 2-1. Three first sliding grooves 2-2-1 are formed on the first platform 2-2. Each first sliding groove 2-2-1 has a vertically arranged limiting rod 2-3 inserted intermittently to form a limiting surface. Parallel first guide rods 2-4 are fixed to the bottom of the first support frame 2-1. A connecting rod 2-5 is slidably arranged between two first guide rods 2-4. The limiting rod 2-3 is vertically fixed to the connecting rod 2-5. A first cylinder 2-6 is fixed to one end of the first support frame 2-1. The piston rod of the first cylinder 2-6 is horizontally arranged and vertically fixed to the connecting rod 2-5. The first cylinder 2-6 drives the limiting rod 2-3 to move the PE bags stacked on the first platform 2-2, which can simultaneously transport multiple PE bags and prevent the PE bags from sliding backward due to inertia through the limiting rod 2-3. A first positioning plate 2-7 is provided on any side of the first platform 2-2 perpendicular to the limiting surface, and a second positioning plate 2-8 is provided on the side of the first platform 2-2 near the bag limiting part 5. By setting the first positioning plate as a reference surface, the front and rear sides of the PE bags stacked on the platform are kept flush. Under the push of the limiting rod and the action of the second positioning plate 2-8, the left and right sides of the PE bags are kept flush, ensuring the positional accuracy of the PE bag conveying.

[0037] The lifting suction bag unit 3 includes a lifting cylinder 3-1 fixedly mounted on the top of the frame 1. The piston rod of the lifting cylinder 3-1 is set vertically downward and fixedly connected to a fixing plate 3-2. The fixing plate 3-2 is evenly provided with multiple pneumatic suction cups 3-3 along its length.

[0038] The translating bag clamping part 4 includes a slide cylinder 4-1 fixedly mounted on the top of the frame 1 and arranged in parallel with a second guide rod 4-2. A moving block 4-3, which is fixedly connected to the sliding block of the slide cylinder 4-1, is slidably mounted on the second guide rod 4-2. A crossbar 4-4 is fixedly suspended on the moving block 4-3. Pneumatic clamps 4-5 are symmetrically arranged at both ends of the crossbar 4-4. The pneumatic clamps 4-5 are provided with opposing grippers to form a clamping opening. Anti-slip soft pads are provided on the inner side of the grippers to provide further protection and prevent the grippers from damaging the PE bag.

[0039] The bag limiting part 5 includes a second support plate 5-1 fixedly installed in the middle of the frame 1. A second platform plate 5-2 is fixedly installed on the top of the second support plate 5-1. Multiple parallel second slide grooves 5-2-1 are opened on the second platform plate 5-2. The second slide grooves 5-2-1 are equipped with adjustable spacing limiting posts 5-3, thereby meeting the bag loading needs of more specifications of PE bags and improving versatility. Specifically, below the second plate 5-2, there is a forward and reverse adjusting screw 5-4 mounted on the second support plate 5-1. Parallel third guide rods 5-5 are arranged on both sides of the forward and reverse adjusting screw 5-4. The forward and reverse threaded areas of the forward and reverse adjusting screw 5-4 are respectively threaded to mounting plates 5-6 that slide with the third guide rods 5-5. A second cylinder 5-7 is fixedly mounted on the mounting plate 5-6. The piston rod of the second cylinder 5-7 passes through the mounting plate 5-6 and is fixedly connected to a first connecting plate 5-8 arranged parallel to the mounting plate 5-6. A limiting post 5-3 is vertically fixedly mounted on the first connecting plate 5-8. The original spacing of the limiting post 5-3 can be quickly adjusted by the forward and reverse adjusting screw 5-4, and then the spacing of the limiting post 5-3 can be adjusted a second time by the cylinder, thus broadening its applicability.

[0040] The second support plate 5-2 has a through groove 5-2-2 near the outlet of the bag limiting section 5. The conveying roller 6-1 is rotatably mounted on the second support plate 5-1 and located at the through groove 5-2-2, with its top slightly higher than the second support plate 5-2. The servo bag conveying section 6 also includes a servo motor 6-2 fixedly mounted on one end of the second support plate 5-1. The output shaft of the servo motor 6-2 is coaxially fixed to the conveying roller 6-1, thereby driving its rotation to realize the conveying of PE bags.

[0041] To prevent the PE bag from shifting during transport, this embodiment also includes a lifting and pressing part 7. The lifting and pressing part 7 includes a pressing cylinder 7-1 fixedly mounted on the top of the frame 1. The pressing cylinder 7-1 is located above the conveying roller 6-1, and the piston rod is set vertically downward and fixedly connected to a second connecting plate 7-2. The second connecting plate 7-2 is set horizontally and has pressing wheels 7-3 rotating at both ends. The pressing wheels 7-3 press the bag body to prevent displacement.

[0042] To improve the conveying position accuracy, this embodiment also includes a lifting bag blocking part 8, which includes a bag blocking cylinder 8-1 fixedly mounted on the frame 1 and located at the outlet of the bag limiting part 5. The piston rod of the bag blocking cylinder 8-1 is vertically upward and fixedly connected to a bag blocking plate 8-2, so that the PE bag stops moving after it moves to contact the bag blocking plate 8-2, thereby achieving automatic positioning and improving the position accuracy of conveying to the next process.

[0043] The workflow of this embodiment:

[0044] An appropriate number of PE packaging bags are laid flat on the right end of the movable bag storage section 2 and are limited by the limiting rods 2-3. The limiting rods push the sides of the PE packaging bags to align them and move them horizontally to the left end of the movable bag storage section 2. This position is the reference position for bag suction.

[0045] When the packaging bag is in place, the limit rods 2-3 reset to receive the next batch of packaging bags. The pneumatic suction cup of the lifting suction unit 3 sucks on the side of the packaging bag, causing it to be lifted to a certain height. The lateral clamping unit 4 moves to clamp the packaging bag, moves it above the bag compartment of the limiting unit 5, and places the packaging bag into the bag compartment defined by the two limiting posts on the second platform.

[0046] The PE packaging bag lies flat on the second plate of the bag limiting section, contacts the conveying roller of the servo bag conveying section 6, and moves forward under the action of friction. At the same time, the cylinder of the lifting and pressing section 7 drives the pressing roller to descend. The pressing roller contacts the body of the packaging bag and presses the bag body to prevent the packaging bag from shifting during the movement.

[0047] The cylinder of the lifting bag baffle 8 drives the bag baffle plate to rise, waiting for the packaging bag to move into the baffle plate. Once the packaging bag contacts the baffle plate, it stops and remains stationary, waiting for the transfer to the next process.

[0048] In this embodiment, the stacked PE bags are first separated by the lifting suction unit, and then the PE bags are transferred by the translating clamping unit. On the one hand, time is saved by reducing the range of motion of individual components. On the other hand, taking into full account the soft and slippery characteristics of PE bags, clamping transfer is used instead of direct suction transfer. The PE bags are transported by the movable bag storage unit, the bag limiting unit and the servo bag conveying unit, which has higher reliability, avoids a long single conveying line, effectively prevents PE bags from deforming and slipping, reduces equipment failure rate and improves production efficiency.

[0049] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
