Description

Technical Field

[0001] This utility model relates to the technical field of cream mask bagging mechanism applicable to similar sizes, and more particularly to a cream mask bagging mechanism applicable to similar sizes. Background Technology

[0002] In the automated bagging production of cream masks, the stable opening and closing and precise positioning of the packaging bag are the core factors that determine the quality of bagging. The performance of the bagging-related structures that undertake this key function directly affects production efficiency and product qualification rate.

[0003] Existing automated equipment structures responsible for opening, closing, and positioning packaging bags exhibit numerous insurmountable shortcomings when faced with the packaging requirements of cream masks of similar sizes. In terms of bag positioning, existing structures lack sufficient constraint on the bag opening edges. Since cream mask packaging bags are mostly made of flexible film, they are easily affected by airflow and equipment vibration during high-speed production, leading to positional shifts. Traditional positioning structures often rely solely on simple stops for limitation, failing to adaptively adjust to subtle dimensional differences in the packaging bags. This results in misalignment between the bag opening and the mask conveying path. When the mask is pushed to the bag opening, it may fail to enter the bag smoothly due to positional deviation, or it may become crooked or wrinkled inside the bag, severely affecting the product's appearance quality. Therefore, a bag-feeding mechanism suitable for cream masks of similar sizes is proposed to solve these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a bag-feeding mechanism suitable for cream masks of similar size. It solves the problem that traditional positioning structures often rely solely on simple blocks for limiting the position, and cannot adaptively adjust to subtle differences in the size of the packaging bags. This results in misalignment between the bag opening and the mask conveying path. When the mask is pushed to the bag opening, it may not be able to enter the bag smoothly due to positional deviation, or the mask may become crooked or wrinkled inside the bag after entering, seriously affecting the product's appearance quality.

[0005] To solve the above technical problems, the present invention provides the following technical solution: a bag-filling mechanism for cream masks of similar size, comprising a fixed base plate, wherein the fixed base plate is provided with a connecting mechanism, the connecting mechanism includes a traction component disposed at one end of the front side of the fixed base plate, a pushing component connected to the top of the traction component, and a bag-filling component connected to the front end of the pushing component.

[0006] The bag-feeding assembly includes a connecting rod, a gear fixedly connected to the outer wall of the connecting rod, a rack plate meshing with the outer wall of the gear, an L-shaped reinforcing block fixedly connected to one end of the front of the rack plate, a connecting rod fixedly connected to the outer wall of the L-shaped reinforcing block, a fixing block fixedly connected to the inner side of the connecting rod, a fixing rod fixedly connected to the inner wall of the fixing block, a stop block fixedly connected to the inner side of the fixing rod, a sliding rod fixedly connected to the bottom of the rack plate, and an opening / closing bag plate fixedly connected to the inner side of the sliding rod.

[0007] A further improvement is that the traction assembly includes a fixing plate fixedly connected to the front side of the fixing base plate, a cylinder is fixedly connected to the outer wall of the fixing plate, a push rod is fixedly connected to the top output end of the cylinder, a push block is fixedly connected to the top of the push rod, and a receiving plate is fixedly connected to the top of the push block.

[0008] A further improvement is that the pusher assembly includes a receiving frame, an L-shaped frame is fixedly connected to the top of the receiving frame, a cylinder two is fixedly installed on the outer wall of the L-shaped frame, a push rod two is fixedly connected to the output end of the front of the cylinder two, a fixed circular block is fixedly connected to the outer wall of the push rod two, a limit ring is fixedly connected to the outer wall of the L-shaped frame, and a hinge block is hinged to the front end of the push rod two.

[0009] A further improvement is that the outer wall of the connecting rod is fixedly connected to the inner wall of the hinge block, and the gear is rotatably connected to the inner wall of the circular groove at the top of the receiving plate. The gear fixed to the outer wall of the connecting rod rotates accordingly, and the gear is rotatably connected to the inner wall of the circular groove at the top of the receiving plate. This connection method not only ensures the flexible rotation of the gear, but also plays a positioning role for it. Since the gear meshes with the rack plate, the rotation of the gear drives the rack plate to slide along the inner wall of the limiting slide groove opened at the top of the receiving plate. The limiting slide groove ensures that the rack plate can only move in a straight line in a predetermined direction, thereby improving the accuracy of the movement.

[0010] A further improvement is that the fixing plates are symmetrically arranged on both sides of the front of the fixing base plate; the fixing plates fixed on both sides of the front of the fixing base plate provide stable support for the cylinder. After receiving the control signal, the top output end of the cylinder pushes the push rod to move upward, thereby driving the push block and the receiving plate to rise synchronously.

[0011] A further improvement is that the receiving frame is fixedly connected to the top of the receiving plate, the fixed circular block is slidably connected to the inner wall of the limiting ring, and the hinge blocks are symmetrically arranged on the top of the receiving frame; when the receiving plate reaches the preset height, the pushing assembly begins to play a power transmission role; the receiving frame fixed on the top of the receiving plate provides a stable installation base for the entire pushing assembly, the cylinder two on the L-shaped frame is activated, and its front output end pushes the push rod two forward.

[0012] A further improvement is that the rack plate is slidably connected to the inner wall of the limiting groove opened at the top of the receiving plate, and the abutment is set at the outer end of the opening and closing bag plate, with the opening and closing bag plate symmetrically arranged on the inner side of the abutment; the gear meshes with the rack plate, and the rotation of the gear drives the rack plate to slide along the inner wall of the limiting groove opened at the top of the receiving plate. The limiting groove ensures that the rack plate can only move in a straight line in a predetermined direction, improving the accuracy of the movement; the sliding of the rack plate triggers a series of chain reactions; the L-shaped reinforcing block fixedly connected to one end of its front moves together with the rack plate, and drives the fixed block and fixed rod to move through the connecting rod, and the abutment on the inner side of the fixed rod moves accordingly.

[0013] By employing the above technical solution, this utility model provides a pouch-filling mechanism suitable for cream masks of similar size, which has at least the following beneficial effects:

[0014] 1. In the traction component of this utility model, the cylinder can drive the receiving plate to adjust the height. The pushing component ensures stable power transmission through the cooperation of the limiting ring and the fixed round block. In the bag insertion component, the meshing transmission of the gear and the rack plate allows for precise adjustment of the opening and closing range of the bag opening and closing plate. When producing cream masks of different sizes but similar, there is no need to make a lot of mechanical modifications to the mechanism. Stable opening and closing of the packaging bag and accurate insertion of the mask can be achieved simply by adjusting the relevant parameters. This greatly reduces changeover time and equipment adjustment costs, and enhances the flexible production capacity of the production line.

[0015] 2. The symmetrical fixing plate of the traction component of this utility model provides stable support for the whole. The symmetrical arrangement of the hinge blocks in the pushing component ensures that the power is evenly transmitted to the bag-feeding component. The design of the rack plate sliding along the limiting groove and the fixed round block sliding along the limiting ring in the bag-feeding component ensures the accuracy of the movement trajectory of each component. The auxiliary positioning of the abutment block on the edge of the packaging bag and the symmetrical movement of the opening and closing bag plate prevent the packaging bag from shifting and the bag opening from opening unevenly. This allows the cream mask to enter the bag smoothly and accurately, reducing problems such as mask jamming, deformation and packaging bag damage, and significantly improving product packaging quality and production efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Traditional positioning structures often rely solely on simple stops for positioning, failing to adapt to subtle dimensional differences in packaging bags. This leads to misalignment between the bag opening and the mask delivery path. When the mask is pushed to the bag opening, it may fail to enter the bag smoothly due to positional deviation, or it may become misaligned or wrinkled inside the bag, severely impacting product appearance quality. This embodiment provides a bag-feeding mechanism suitable for cream masks of similar sizes. Please refer to... Figures 1-5The embodiment provides a bag-filling mechanism suitable for cream masks of similar size, including a fixed base plate 1. The fixed base plate 1 is provided with a connecting mechanism 2. The connecting mechanism 2 includes a traction component 21 disposed at one end of the front of the fixed base plate 1. A pushing component 22 is connected to the top of the traction component 21. A bag-filling component 23 is connected to the front end of the pushing component 22. The bag-filling component 23 includes a connecting rod 231. A gear 232 is fixedly connected to the outer wall of the connecting rod 231. A rack plate 233 meshes with the outer wall of the gear 232. An L-shaped reinforcing block 234 is fixedly connected to one end of the front of the rack plate 233. A connecting rod 235 is fixedly connected to the outer wall of the L-shaped reinforcing block 234. A fixing block 236 is fixedly connected to the inner side of the connecting rod 235. A fixing rod 237 is fixedly connected to the inner wall of the fixing block 236. A stop block 238 is fixedly connected to the inner side of the fixing rod 237. A sliding rod 2310 is fixedly connected to the bottom of the rack plate 233. An opening and closing bag plate 2311 is fixedly connected to the inner side of the sliding rod 2310.

[0027] In this embodiment, in the bag assembly 23, the transmission and conversion of power further realizes the opening and closing operation of the bag opening; the outer wall of the connecting rod 231 is fixedly connected to the inner wall of the hinge block 227, so the angle change of the hinge block 227 drives the connecting rod 231 to rotate synchronously; the gear 232 fixed on the outer wall of the connecting rod 231 rotates accordingly, and the gear 232 is rotatably connected to the inner wall of the circular groove at the top of the receiving plate 215. This connection method not only ensures the flexible rotation of the gear 232, but also plays a positioning role for it; since the gear 232 meshes with the rack plate 233, the rotation of the gear 232 drives the rack plate 233 to slide along the inner wall of the limiting slide groove opened at the top of the receiving plate 215. The limiting slide groove ensures that the rack plate 233 can only move in a straight line in a predetermined direction, improving the accuracy of the movement; the sliding of the rack plate 233 triggers a series of chain reactions; its front side The L-shaped reinforcing block 234, which is fixedly connected to the end, moves together with the rack plate 233. Through the connecting rod 235, it drives the fixed block 236 and the fixed rod 237 to move, and the abutment block 238 on the inner side of the fixed rod 237 moves accordingly. The abutment block 238 is set at the outer end of the opening and closing bag plate 2311. During the movement, it can assist in positioning the edge of the packaging bag to prevent the packaging bag from shifting during the opening and closing process. At the same time, the sliding rod 2310, which is fixedly connected to the bottom of the rack plate 233, drives the opening and closing bag plate 2311 to move. Since the opening and closing bag plate 2311 is symmetrically arranged on the inner side of the abutment block 238, under the drive of the rack plate 233, the opening and closing bag plates 2311 on both sides will move closer or further away from each other, thereby achieving precise opening and closing of the packaging bag opening. When the bag opening is opened to the appropriate degree, the external conveying device delivers the cream mask to the bag opening. With the coordinated action of each component, the mask smoothly enters the packaging bag.

[0028] Furthermore, the outer wall of the connecting rod 231 is fixedly connected to the inner wall of the hinge block 227, and the gear 232 is rotatably connected to the inner wall of the circular groove at the top of the receiving plate 215; the rack plate 233 is slidably connected to the inner wall of the limiting groove opened at the top of the receiving plate 215, and the abutment block 238 is set at the outer end of the opening and closing bag plate 2311, and the opening and closing bag plate 2311 is symmetrically arranged on the inner side of the abutment block 238.

[0029] Furthermore, the gear 232 fixed to the outer wall of the connecting rod 231 rotates accordingly, and the gear 232 is rotatably connected to the inner wall of the circular groove at the top of the receiving plate 215. This connection method not only ensures the flexible rotation of the gear 232, but also plays a positioning role for it. Since the gear 232 meshes with the rack plate 233, the rotation of the gear 232 drives the rack plate 233 to slide along the inner wall of the limiting slide groove opened at the top of the receiving plate 215. The limiting slide groove ensures that the rack plate 233 can only move in a straight line in a predetermined direction, thereby improving the accuracy of the movement.

[0030] Example 2

[0031] Based on Embodiment 1, the traction assembly 21 includes a fixing plate 211 fixedly connected to the front side of the fixing base plate 1. A cylinder 212 is fixedly connected to the outer wall of the fixing plate 211. A push rod 213 is fixedly connected to the top output end of the cylinder 212. A push block 214 is fixedly connected to the top of the push rod 213. A receiving plate 215 is fixedly connected to the top of the push block 214. The holding assembly 22 includes a receiving frame 221. An L-shaped frame 222 is fixedly connected to the top of the receiving frame 221. A cylinder 223 is fixedly installed on the outer wall of the L-shaped frame 222. A push rod 224 is fixedly connected to the output end of the front side of the cylinder 223. A fixing block 225 is fixedly connected to the outer wall of the push rod 224. A limit ring 226 is fixedly connected to the outer wall of the L-shaped frame 222. A hinge block 227 is hinged to the front side of the push rod 224.

[0032] In this embodiment, when the equipment is started, the traction component 21 starts working first; the fixing plates 211 fixed on both sides of the front of the fixing base plate 1 provide stable support for the cylinder 212. After receiving the control signal, the top output end of the cylinder 212 pushes the push rod 213 upward, thereby driving the push block 214 and the receiving plate 215 to rise synchronously; the rising height of the receiving plate 215 can be adjusted according to the position of the packaging bag in actual production to ensure that the subsequent bag insertion component 23 can be accurately aligned with the packaging bag, creating suitable space conditions for the subsequent bag opening and closing and mask insertion operation; as the receiving plate 215 reaches the preset height, the pushing component 22 begins to play the role of power transmission; the receiving frame 221 fixed on the top of the receiving plate 215 provides support for the entire The push-support assembly provides a stable installation base. The cylinder 223 on the L-shaped frame 222 is activated, and its front output end pushes the push rod 224 forward. At this time, the fixed circular block 225 fixed on the outer wall of the push rod 224 slides along the inner wall of the limiting ring 226. The limiting ring 226 plays a strict guiding and limiting role on the movement of the fixed circular block 225, effectively preventing the push rod 224 from deviating or shaking during the movement, and ensuring the stability of power transmission. Since the front end of the push rod 224 is hinged to the hinge block 227, and the hinge block 227 is symmetrically arranged on the top of the receiving frame 221, the forward movement of the push rod 224 causes the two hinge blocks 227 to change angles simultaneously, and the power is evenly transmitted to the bag-feeding assembly 23.

[0033] Furthermore, the fixing plate 211 is symmetrically arranged on both sides of the front of the fixing base plate 1; the receiving frame 221 is fixedly connected to the top of the receiving plate 215, the fixing round block 225 is slidably connected to the inner wall of the limiting ring 226, and the hinge block 227 is symmetrically arranged on the top of the receiving frame 221.

[0034] Furthermore, the receiving frame 221 fixed to the top of the receiving plate 215 provides a stable mounting base for the entire push assembly. The cylinder 223 on the L-shaped frame 222 is activated, and its front output end pushes the push rod 224 forward. At this time, the fixed round block 225 fixed to the outer wall of the push rod 224 slides along the inner wall of the limiting ring 226. The limiting ring 226 plays a strict guiding and limiting role on the movement of the fixed round block 225, effectively preventing the push rod 224 from deviating or shaking during the movement, and ensuring the stability of power transmission.

[0035] Working principle: When the equipment is started, the traction component 21 starts working first; the fixing plates 211 fixed on both sides of the front of the fixing base plate 1 provide stable support for the cylinder 212. After receiving the control signal, the top output end of the cylinder 212 pushes the push rod 213 upward, thereby driving the push block 214 and the receiving plate 215 to rise synchronously; the rising height of the receiving plate 215 can be adjusted according to the position of the packaging bag in actual production to ensure that the subsequent bag insertion component 23 can be accurately aligned with the packaging bag, creating suitable space conditions for the subsequent bag opening and closing and mask insertion operation; as the receiving plate 215 reaches the preset height, the pushing component 22 begins to play the role of power transmission; the receiving frame 221 fixed on the top of the receiving plate 215 provides support for the entire pushing component 212. The support assembly provides a stable installation base. When cylinder 223 on the L-shaped frame 222 is activated, its front output end pushes push rod 224 forward. At this time, the fixed circular block 225 fixed to the outer wall of push rod 224 slides along the inner wall of the limiting ring 226. The limiting ring 226 plays a strict guiding and limiting role on the movement of the fixed circular block 225, effectively preventing push rod 224 from deviating or shaking during the movement, and ensuring the stability of power transmission. Since the front end of push rod 224 is hinged to hinge block 227, and hinge block 227 is symmetrically arranged on the top of the receiving frame 221, the forward movement of push rod 224 causes the two hinge blocks 227 to change angles simultaneously, and the power is evenly transmitted to the bag insertion assembly 23.

[0036] In the bag assembly 23, the transmission and conversion of power further realizes the opening and closing operation of the bag opening; the outer wall of the connecting rod 231 is fixedly connected to the inner wall of the hinge block 227, so the angle change of the hinge block 227 drives the connecting rod 231 to rotate synchronously; the gear 232 fixed on the outer wall of the connecting rod 231 rotates accordingly, and the gear 232 is rotatably connected to the inner wall of the circular groove at the top of the receiving plate 215. This connection method not only ensures the flexible rotation of the gear 232, but also plays a positioning role for it; since the gear 232 meshes with the rack plate 233, the rotation of the gear 232 drives the rack plate 233 to slide along the inner wall of the limiting slide groove opened at the top of the receiving plate 215. The limiting slide groove ensures that the rack plate 233 can only move in a straight line in a predetermined direction, improving the accuracy of the movement; the sliding of the rack plate 233 triggers a series of chain reactions; one end of its front is fixedly connected to The L-shaped reinforcing block 234 moves together with the rack plate 233, and drives the fixed block 236 and fixed rod 237 to move through the connecting rod 235. The abutment block 238 on the inner side of the fixed rod 237 moves accordingly. The abutment block 238 is set at the outer end of the opening and closing bag plate 2311. During the movement, it can assist in positioning the edge of the packaging bag to prevent the packaging bag from shifting during the opening and closing process. At the same time, the sliding rod 2310 fixedly connected to the bottom of the rack plate 233 drives the opening and closing bag plate 2311 to move. Since the opening and closing bag plate 2311 is symmetrically arranged on the inner side of the abutment block 238, under the drive of the rack plate 233, the opening and closing bag plates 2311 on both sides will move closer or further away from each other, thereby achieving precise opening and closing of the bag opening. When the bag opening is opened to the appropriate degree, the external conveying device delivers the cream mask to the bag opening. With the coordinated action of each component, the mask smoothly enters the packaging bag.

[0037] After the bagging operation is completed, cylinder 212 and cylinder 223 operate in opposite directions, driving push rod 213, push rod 224 and other components to reset, thereby returning each component of the bagging assembly 23 to its initial position, preparing for the next bagging operation; throughout the entire operation, the cooperation between the components is close and orderly, and through precise power transmission, strict motion guidance and positioning, the efficiency and stability of the bagging operation of cream masks of similar size are ensured.
