Description

Technical Field

[0001] This utility model relates to the field of packaging equipment, and in particular to a valve bag swing-type switching bag-making device. Background Technology

[0002] The bagging device is a special device used on the packaging production line to put the opened packaging bags onto the discharge port. Existing bagging devices are generally equipped with one bagging device for each discharge port. However, in actual use, because the discharge process takes a certain amount of time, it is often necessary to pause for a period of time after bagging to wait for the filling to be completed before continuing. The overall production rhythm is slow and the efficiency is not high. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide a valve bag swing-type switching bagging device, which can alternately bag the discharge pipes on both sides by swinging, thereby improving the overall efficiency of the production line.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A valve pocket swing-type switching bagging device is provided, comprising: a horizontal drive cylinder, a guide rail, a translation trolley, a side-swing drive cylinder, a swing frame, and a bag clamping mechanism. The translation trolley is mounted on the guide rail. The telescopic rod end of the horizontal drive cylinder is connected to the translation trolley, enabling it to drive the translation trolley to move horizontally reciprocally along the guide rail. The swing frame is mounted on the belly of the translation trolley. The side-swing drive cylinder is mounted on one side of the translation trolley, and its telescopic rod is connected to the swing frame. The bag clamping mechanism is mounted on the lower part of the swing frame. The side-swing drive cylinder can drive the swing frame to drive the bag clamping mechanism to perform a pendulum motion perpendicular to the direction of the guide rail. The bag clamping mechanism includes a clamping bracket, a synchronous drive cylinder, and a clamp. The clamping bracket includes a hanging plate, a support column, and a base frame. The hanging plate is fixed to the top of the support column to form a T-shape. There are two synchronous drive cylinders, symmetrically suspended at both ends of the hanging plate. The base frame is fixed to the bottom of the support column and is fixedly connected to the bottom of the swing frame. Two sets of rotary joints are symmetrically installed on the base frame about the support column. Each set includes two coaxial rotary joints. The clamp includes two bag-grabbing arms that face each other and hug each other. A bag-closing plate is installed on the inner side of each bag-grabbing arm. The two bag-closing plates are exactly opposite each other. The top of each bag-grabbing arm is connected to a set of rotary joints. A bag-grabbing rod is installed at the lower end of each bag-grabbing arm. The telescopic rod end of the synchronous drive cylinder on the corresponding side of each bag-grabbing arm is movably connected to the upper arm of the corresponding bag-grabbing arm.

[0005] In a preferred embodiment of this utility model, the swing frame includes an active swing rod, a passive swing rod, and a swing platform. The top ends of the active swing rod and the passive swing rod are rotatably mounted below the translation trolley. The top end of the telescopic rod of the side swing drive cylinder is hinged to the rod body of the active swing rod. The swing platform is simultaneously connected to the lower ends of the active swing rod and the passive swing rod, enabling translational movement when the swing frame swings. The base frame is vertically fixed to the outside of the swing platform. The swing platform includes a swing rod connecting frame, a swing shaft, a keel support plate, and a base frame connecting plate. The swing rod connecting frame consists of two parallel support plates. There are two swing shafts, which are installed parallel to each other on the swing rod connecting frame and perpendicular to the two support blocks. One swing shaft is hinged at both ends to two hangers symmetrically arranged at the tail end of the active swing rod, and the other swing shaft is hinged at both ends to two hangers symmetrically arranged at the tail end of the passive swing rod. The distance between the two swing shafts is equal to the distance between the top ends of the active swing rod and the passive swing rod. Part of the keel support plate is fixed on the swing rod connecting frame between the two swing shafts, and the other part extends forward. There are two base frame connecting plates, which are fixed parallel to each other on the keel support plate and are fixedly connected to both sides of the base frame.

[0006] In a preferred embodiment of this utility model, the translation trolley includes a frame and four clamping wheel pairs. The guide rail consists of two parallel slide rails. The frame is divided into four corners, with four clamping wheel pairs installed in pairs. Each clamping wheel pair includes an upper roller and a lower roller. The upper rollers and lower rollers of two clamping wheel pairs on the same side clamp the slide rails on the corresponding sides in the middle of the wheel surface. The frame consists of upper and lower frames. The upper frame of the frame connects the upper rollers of the four clamping wheel pairs together. A hinge joint connected to the top end of the telescopic rod of the horizontal drive cylinder is installed on the center line of the upper frame. A swing seat and a bottom plate are installed sequentially along the center line on the belly of the lower frame of the frame. The upper end of the swing frame is connected to the swing seat. The side swing drive cylinder is connected to the translation trolley through the bottom plate. A follower rod is provided between the side-swing drive cylinder and the bottom plate. The tail end of the cylinder body of the side-swing drive cylinder is hinged to one end of the follower rod. The body of the follower rod is fixed to the bottom plate and perpendicular to the guide rail. The other end of the follower rod passes through the translation trolley and is connected to the cable chain.

[0007] The beneficial effects of this utility model are as follows: This utility model is designed to match the overall optimization of existing packaging production lines. By setting two discharge ports on both sides of the bagging mechanism, and then adding a swing drive to the linear motion of the existing bagging mechanism, the main body of the bagging mechanism can swing left and right, thereby realizing the alternating switching of bagging between the two discharge pipes. This alternating bagging and filling on both sides can effectively avoid the rhythm interruption caused by the filling time during the single-line bagging process, significantly increasing the overall efficiency of the production line, and the layout of the entire production line is more compact.

[0010] Please see Figures 1 to 15 The embodiments of this utility model include: A valve bag swing-type switching bagging device includes: a horizontal drive cylinder 1, a guide rail 5, a translation trolley 4, a side-swing drive cylinder 2, a swing frame 8, and a bag clamping mechanism. The translation trolley 4 is mounted on the guide rail 5. The telescopic rod end of the horizontal drive cylinder 1 is connected to the translation trolley 4, enabling it to drive the translation trolley 4 to reciprocate horizontally along the guide rail 5. The swing frame 8 is mounted on the belly of the translation trolley 4. The side-swing drive cylinder 2 is mounted on the horizontal drive cylinder 5. Moving the trolley 4 to one side, the telescopic rod of the side-swing drive cylinder 2 is connected to the swing frame 8. The bag clamping mechanism is installed at the lower part of the swing frame 8. The side-swing drive cylinder 2 can push the swing frame 8 to drive the bag clamping mechanism to perform a pendulum motion perpendicular to the direction of the guide rail 5. The bag clamping mechanism includes a clamping bracket 6, a synchronous drive cylinder 3, and a clamp 7. The clamping bracket 6 includes a hanging plate 601, a support column 602, and a base frame 603. The hanging plate 601 is fixed to the top of the support column 602 to form a T-shaped structure. There are two synchronous drive cylinders 3, symmetrically suspended at both ends of the hanging plate 601. The base frame 603 is fixed to the bottom of the support column 602 and is fixedly connected to the bottom of the swing frame 8. Two sets of rotary joints 604 are symmetrically installed on the base frame 603 about the support column. Each set includes two coaxial rotary joints 604. The clamp 7 includes two opposing gripping arms 701. A clamping frame 704 is installed on the inner side of each gripping arm 701. A clamping plate is installed on the clamping frame 704. 703, the two bag clamping plates 703 are exactly opposite each other, the top ends of the two bag gripping arms 701 are respectively connected to a set of rotary joints 604, the lower end of each bag gripping arm 701 is equipped with a bag gripping rod 702, the telescopic rod end of the synchronous drive cylinder 3 on the corresponding side of each bag gripping arm 701 is also movably connected to the upper arm of the corresponding bag gripping arm 701, the telescopic rods of the two synchronous drive cylinders 3 extend and retract at the same time, which can drive the two bag gripping arms 701 to open or close at the same time, and the bag clamping plates 703 on the inner side of the two bag gripping arms 701 also open or close synchronously.

[0011] The swing frame 8 includes an active swing rod 801, a passive swing rod 802, and a swing platform 803. The top ends of the active swing rod 801 and the passive swing rod 802 are rotatably mounted below the translation trolley 4. The top end of the telescopic rod of the side swing drive cylinder 2 is hinged to the rod body of the active swing rod 801. The swing platform 803 is simultaneously connected to the lower ends of the active swing rod 801 and the passive swing rod 802, enabling the entire frame to perform translational movement when the swing frame 8 swings. The base frame 603 is vertically fixed to the outside of the swing platform 803. The swing platform 803 includes a swing rod connecting frame 8031, a swing shaft 8033, a keel support plate 8032, and a base frame connecting plate 8034. The swing rod connecting frame 8031 ​​is composed of two parallel support plates. There are two swing shafts 8033, which are installed parallel to each other on the swing rod connecting frame 8031 ​​and perpendicular to the two support blocks. One swing shaft 8033 is hinged at both ends to two hangers symmetrically arranged at the tail end of the active swing rod 801, and the other swing shaft 8033 is hinged at both ends to the opposite... Two hinge joints are mounted at the tail end of the passive swing arm 802. The distance between the two swing shafts 8033 is equal to the distance between the top ends of the active swing arm 801 and the passive swing arm 802. Part of the keel support plate 8032 is fixed to the swing arm connecting frame 8031 ​​between the two swing shafts 8033, and the other part extends forward. There are two base frame connecting plates 8034, which are fixed parallel to the keel support plate 8032 and are fixedly connected to both sides of the base frame 603. In this way, when the swing frame 8 swings to both sides, the clamping bracket 6 can stably maintain a vertically downward state, unaffected by the swinging motion, thereby ensuring the stability of the clamping action of the chuck 7.

[0012] The translation trolley 4 includes a frame 401 and four clamping wheel pairs 402. The guide rail 5 consists of two parallel slide rails. The four clamping wheel pairs 402 are installed in pairs at the four corners of the frame 401. Each clamping wheel pair 402 includes an upper roller and a lower roller. The upper roller and lower roller of the two clamping wheel pairs on the same side clamp the slide rail on the corresponding side in the middle of the wheel surface. The frame 401 consists of upper and lower frames. The upper frame of the frame 401 connects the upper rollers of the four clamping wheel pairs 402 together. A hinge joint 406 connected to the top end of the telescopic rod of the horizontal drive cylinder 1 is installed on the center line of the upper frame. A swing seat 404 and a bottom plate 406 are installed sequentially along the center line of the lower frame of the frame. The upper end of the swing frame 4 is connected to the swing seat 404. The side swing drive cylinder 2 is connected to the translation trolley 4 through the bottom plate 406. With this structure, the translation trolley 4 can move the lower swing frame 8 and the clamping mechanism together as a whole when pushed by the horizontal drive cylinder 1.

[0013] A follower rod 9 is provided between the side-swing drive cylinder 2 and the bottom plate 406. The tail end of the cylinder body of the side-swing drive cylinder is hinged to one end of the follower rod. The body of the follower rod 9 is fixed to the bottom plate 406 and perpendicular to the direction of the guide rail 5. The other end of the follower rod 9 passes through the translation trolley 4 and connects to the cable chain 10. By using the follower rod 9 to support the side-swing drive cylinder 2, the translation trolley 4 can move along with it, keeping the whole structure relatively stationary. This ensures the stability of the swing when the swing frame 8 is pushed to swing. Furthermore, the connection between the follower rod 9, which passes through the translation trolley 4, and the cable chain 10 improves the balance of the entire structure and further enhances the overall stability.

[0014] This utility model can rely on the horizontal drive cylinder 1 and the side swing drive cylinder 2 to make the clamping mechanism reciprocate along the guide rail 5 and swing left and right relative to the guide rail 5. In actual use, it can cooperate with the bag holding mechanism and the bag supporting mechanism. First, the bag with the valve opening supported by the bag supporting mechanism is flipped down and clamped by the bag holding mechanism. Then, the bag supporting mechanism is released and exits the valve opening. Next, the side swing drive cylinder 2 drives the clamping mechanism to swing to one side and, driven by the horizontal drive cylinder 1, puts the bag on one side of the discharge pipe. After putting it on, it returns to the initial bag taking position. The next bag with the valve opening supported is flipped down and clamped by the bag holding mechanism. The above steps are repeated to swing to the other side and put the bag on the other side of the discharge pipe.

[0015] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
