Description

Technical Field

[0001] This utility model relates to the field of automatic bag ejector technology, and in particular to an automatic bag ejector for valve bags. Background Technology

[0002] With the continuous development of industrial production, the application of automated equipment is becoming more and more widespread. In the packaging process of powdery and granular materials, traditional manual operation is not only inefficient, but also prone to environmental pollution and unstable product quality. Therefore, an automatic valve bag injection machine is needed.

[0003] A search revealed Chinese patent publication number CN108502262B, entitled "An Integrated System and Control Method for Automatic Valve Bag Loading." This system includes a system control module, a conveyor, a filling machine, a robot module equipped with a dedicated end effector, and a vision module containing a camera and light source. The end effector includes a pick-up suction cup, a clamping plate, and a bag-opening suction cup. The operation control method is as follows: the system control module controls the conveyor to stop the valve bag below the camera, extracts the position and orientation coordinates of the valve opening, and transmits them to the robot module; the robot module controls the pick-up path and bag-loading path of the end effector based on the coordinate information, thus controlling the end effector... The operator reliably completes the positioning, picking up, clamping, opening, and bagging of valve bags by placing the opened valve on the feeding pipe, saving manpower and improving efficiency. It is flexible and can complete the bagging operation of various valve bags. It adopts commercial robots and vision modules, which simplifies the mechanical structure, improves system reliability, and reduces costs. However, existing automatic bag injection machines mainly rely on suction cups to pick up the bags and then transport them to the set position through a conveying device. During the suction cup picking process, static electricity can easily exist between adjacent bags, causing them to stick together, which affects the working efficiency of the bag injection machine. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic valve bag injection machine, which aims to improve the problem in the prior art where static electricity easily exists between two adjacent bags during the suction process, causing the two adjacent bags to stick together and thus affecting the working efficiency of the injection machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic valve bag injection machine, comprising an outer frame, a support frame provided at the bottom of the outer wall of the outer frame, two bag conveying chains provided on each adjacent side of the support frame, bag conveying plates provided on the outer walls of the two bag conveying chains, a rotating block fixedly connected to the front left side of the outer wall of the support frame, a hydraulic rod rotatably connected to the outer wall of the rotating block, a striking plate rotatably connected to the other end of the hydraulic rod, connecting columns fixedly connected to the left and right sides of the middle of the outer wall of the outer frame, baffles fixedly connected to the outer walls of the two connecting columns, a plurality of suction cups I fixedly connected to the bottom of the two baffles, suction cups II provided on the rear side of the outer wall of the plurality of suction cups I, a clamping plate provided at the top of the baffles, and a fixing mechanism provided on the rear side of the bottom of the outer wall of the outer frame.

[0006] The above technical solution utilizes an automatic valve bag injection machine with an outer frame as its main support structure. The support frame at the bottom of the outer frame carries and supports the bag conveyor. A rotating block at the front left side of the support frame is connected to a hydraulic rod, the other end of which is connected to a striking plate to strike the bag. The valve bag is placed on the bag conveyor plate of the bag conveyor chain, which moves the valve bag forward. When the valve bag reaches the appropriate position, the hydraulic rod extends under the support of the rotating block, driving the striking plate to strike the valve bag, such as to help the bag unfold or to better coordinate it with other components. Simultaneously, suction cups one and two at the bottom of the baffle activate, using vacuum suction to hold the valve bag in place, facilitating bag handling and positioning. Clamping plates tighten the top of the valve bag, further securing it and ensuring its stability during subsequent operations, before the bag injection process begins.

[0007] As a further description of the above technical solution:

[0008] The fixing mechanism includes a fixing rod, the rear side of the outer wall of the fixing rod is connected to the rear side of the outer wall of the outer frame, a connecting shell is fixedly connected to the right side of the outer wall of the fixing rod, a connecting rod is fixedly connected to the outer wall of the connecting shell, and a fixing block is fixedly connected to the other end of the connecting rod.

[0009] The above technical solution uses a connecting rod as a key component to enable the movement of the fixed block. One end of the fixed rod is rotatably connected to the connecting shell, and the other end is rotatably connected to the fixed block. This rotatable connection allows the fixed block to move flexibly relative to the fixed rod and the connecting shell within a certain range, thereby enabling the fixing or loosening of the target object.

[0010] As a further description of the above technical solution:

[0011] Each of the adjacent sides of the support frame is fixedly connected to a connecting rod three, and the outer walls of both connecting rods three are provided with crossbars.

[0012] The above technical solution involves reinforcing the connection points between the connecting rod 3 and the support frame and crossbar, increasing the number of connection points, and improving the firmness and stability of the connection. Especially in working environments where the equipment is subject to significant vibration or impact, reinforcing the connection points can effectively prevent the safety hazards of loosening and falling off the connecting rod 3 or crossbar, ensuring the reliability and safety of the entire structure.

[0013] As a further description of the above technical solution:

[0014] The bottom of the support frame is fixedly connected to multiple support columns, and the bottom of each of the multiple support columns is fixedly connected to a support plate.

[0015] The above technical solution involves the bottom of the support column directly contacting the ground. Its main function is to increase the contact area between the support column and the ground, thereby reducing the pressure on the ground and preventing the support column from sinking into the ground due to excessive pressure, thus ensuring the stability of the entire structure.

[0016] As a further description of the above technical solution:

[0017] Support plates are provided on the front and rear sides of the bottom of the outer frame. The top of each support plate has a groove, and the inner walls of the two grooves are fixedly connected to the front and rear sides of the bottom of the outer frame.

[0018] The above technical solution increases the contact area between the bottom of the outer frame and the placement surface by using a support plate, which helps to distribute the weight borne by the outer frame, thereby improving the stability of the entire equipment placement. At the same time, it provides a certain degree of protection for the bottom of the frame, preventing the bottom of the frame from directly contacting the ground or other placement surfaces and being worn or corroded.

[0019] As a further description of the above technical solution:

[0020] Both connecting posts have screws threaded onto their outer walls, and the outer walls of the two screws are threaded onto the top of the baffle.

[0021] The above technical solution uses screws to connect the key component between the connecting column and the baffle. One end of the screw is threaded to the outer wall of the connecting column, and the other end is threaded to the top of the baffle. By rotating the screw, the tightness of the connection between the baffle and the connecting column can be adjusted, thereby ensuring that the baffle is installed in an accurate and stable position.

[0022] As a further description of the above technical solution:

[0023] The two screws are fixedly connected to the outer wall of the connecting column at equal intervals, and the connecting column is threadedly connected to the baffle by the screws.

[0024] The above technical solution involves two screws that are equidistantly fixed to the outer wall of the connecting column. This equidistant distribution makes the connection force between the connecting column and the baffle more uniform, thereby enhancing the stability of the overall connection structure. The connecting column is threadedly connected to the baffle through screws, forming a reliable fixed structure that can effectively limit the movement of the baffle relative to the connecting column.

[0025] As a further description of the above technical solution:

[0026] A second connecting rod is fixedly connected to the outer wall of the fixing block, and the bottom of the outer wall of the second connecting rod is fixedly connected to the clamping plate.

[0027] The above technical solution ensures the stability of the structure during use by fixing the block and connecting rod 2, and by fixing connecting rod 2 and clamping plate. This allows the clamping plate to reliably clamp the object, preventing loosening or displacement and ensuring the accuracy and reliability of the work.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, by setting two bag conveyor chains on the adjacent side of the support frame and equipping them with bag conveyor plates, the bags can be stably and efficiently conveyed to the bags, ensuring the rapid and orderly movement of the bags in the production process, greatly improving production efficiency and reducing the tediousness and time cost of manual operation.

[0030] 2. In this utility model, the connection between the fixing rod and the rear side of the outer frame provides a stable foundation support for the entire fixing mechanism, enabling it to be firmly attached to the main structure and effectively resist various external vibrations and impacts, ensuring that it will not easily shift or loosen during equipment operation.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0039] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model provides an automatic valve bag injection machine, including an outer frame 1, a support frame 3 at the bottom of the outer wall of the outer frame 1, two bag conveying chains 5 on each adjacent side of the support frame 3, bag conveying plates 4 on the outer walls of the two bag conveying chains 5, a rotating block 6 fixedly connected to the front left side of the outer wall of the support frame 3, a hydraulic rod 7 rotatably connected to the outer wall of the rotating block 6, a striking plate 8 rotatably connected to the other end of the hydraulic rod 7, connecting columns 9 fixedly connected to the left and right sides of the middle of the outer wall of the outer frame 1, baffles 10 fixedly connected to the outer walls of the two connecting columns 9, multiple suction cups 11 fixedly connected to the bottom of the two baffles 10, suction cups 12 on the rear side of the outer wall of the multiple suction cups 11, a clamping plate 13 on the top of the baffles 10, and a fixing mechanism 2 on the rear side of the bottom of the outer wall of the outer frame 1.

[0040] Specifically, the valve bag is placed on the bag conveying plate 4, and the bag conveying chain 5 drives the bag conveying plate 4 to move, thereby conveying the bag along the support frame 3 towards the bag injection mechanism. When the bag moves to a certain position with the conveying chain and approaches the rotating block 6, the hydraulic rod 7 performs telescopic movement under the action of the hydraulic system. Since one end of the hydraulic rod 7 is rotatably connected to the rotating block 6 and the other end is connected to the striking plate 8, the telescopic movement of the hydraulic rod 7 drives the striking plate 8 to reciprocate, striking the adjacent bags. At the same time, when the bag moves below the baffle 10, the suction cup 11 and suction cup 12 at the bottom of the baffle 10 start to work. Suction cup 11 picks up the opening of the bag, and suction cup 12 picks up the tail of the bag. After suction cup 11 picks up the opening of the bag, the clamping plate 13 on the top of the baffle 10 moves downward to clamp the opening of the bag. Because the opening of the bag is picked up by suction cup 11 and the clamping plate 13 applies clamping force, the bag is stably fixed and in an open state, ensuring that the valve bag automatic injection machine operates efficiently and stably.

[0041] Reference Figure 1 and Figure 4 The fixing mechanism 2 includes a fixing rod 201. The rear side of the outer wall of the fixing rod 201 is connected to the rear side of the outer wall of the outer frame 1. A connecting shell 202 is fixedly connected to the right side of the outer wall of the fixing rod 201. A connecting rod 203 is fixedly connected to the outer wall of the connecting shell 202. A fixing block 204 is fixedly connected to the other end of the connecting rod 203.

[0042] Specifically, connecting rod 203 is rotatably connected to connecting shell 202, and power drives connecting rod 203 to rotate about the connection point on connecting shell 202. This rotation changes the angle between connecting rod 203 and connecting shell 202, and the rotation of connecting rod 203 will cause the fixed block 204, which is rotatably connected to it, to move. Because the fixed block 204 is also rotatably connected to connecting rod 203, the fixed block 204, driven by connecting rod 203, moves in an arc around its connection point with connecting rod 203, gradually approaching the target object that needs to be fixed.

[0043] Reference Figure 2 , Figure 3 and Figure 4 Each side of the support frame 3 is fixedly connected with a connecting rod 14, and the outer walls of the two connecting rods 14 are provided with crossbars 15; the bottom of the support frame 3 is fixedly connected with multiple support columns 16, and the bottom of the multiple support columns 16 is fixedly connected with support plates 17; the bottom of the outer wall of the outer frame 1 is provided with support plates 19 on the front and rear sides, and the top of the two support plates 19 is provided with grooves 18, and the inner walls of the two grooves 18 are fixedly connected to the bottom front and rear sides of the outer frame 1.

[0044] Specifically, connecting rod 3 14 is fixed to the adjacent side of support frame 3, providing a stable support point for crossbar 15. Crossbar 15 is installed on the outer wall of connecting rod 3 14, and its main function is to expand the functionality of support frame 3. Support plate 17 is in direct contact with the ground, and its large area can distribute the concentrated force transmitted from support column 16 to a larger ground area, thereby reducing the pressure on the ground. Support plates 19 are provided on the front and rear sides of the bottom of the outer wall of outer frame 1, and are tightly fixed to the front and rear sides of the bottom of outer frame 1 through the groove 18 opened at the top, which enhances the stability and structural strength of the bottom of outer frame 1.

[0045] Reference Figure 1 , Figure 4 and Figure 5 Both connecting columns 9 have screws 20 threadedly connected to their outer walls, and the outer walls of the two screws 20 are threadedly connected to the top of the baffle 10; both screws 20 are fixedly connected to the outer walls of the connecting columns 9 at equal intervals, and the connecting columns 9 are threadedly connected to the baffle 10 through the screws 20; the outer wall of the fixing block 204 is fixedly connected to the second connecting rod 21, and the bottom of the outer wall of the second connecting rod 21 is fixedly connected to the clamping plate 13.

[0046] Specifically, the connecting column 9 is fixed to the left and right sides of the middle of the outer wall of the outer frame 1. The outer wall of the connecting column 9 is threaded, and the matching screw 20 is screwed into the thread of the connecting column 9 at one end. The two screws 20 are fixed at equal intervals on the outer wall of the connecting column 9. This equal distribution ensures the positional accuracy and symmetry of the baffle 10 on the connecting column 9 when the baffle 10 is installed. Align the threaded hole at the top of the baffle 10 with the screw 20 that has been screwed into the connecting column 9, and then rotate the baffle 10 or use a tool to tighten the screw 20 so that the screw 20 is gradually screwed into the threaded hole at the top of the baffle 10. When the fixing block 204 is subjected to external driving force, the connecting rod 21 is fixedly connected to the outer wall of the fixing block 204 and will move synchronously with the movement of the fixing block 204. The bottom of the outer wall of the connecting rod 21 is fixedly connected to the clamping plate 13. The movement of the connecting rod 21 will drive the clamping plate 13 to move accordingly.

[0047] Working principle: After the automatic valve bag injection machine is started, the operator places the valve bag on the bag conveyor plate 4. Above, the bag conveyor chain 5 drives the bag conveyor plate 4 to move, thereby conveying the bag along the support frame 3 towards the bag injection mechanism. When the bag moves to a certain position with the conveyor chain and approaches the rotating block 6, the hydraulic rod 7 performs telescopic movement under the action of the hydraulic system. Since one end of the hydraulic rod 7 is rotatably connected to the rotating block 6 and the other end is connected to the striking plate 8, the telescopic movement of the hydraulic rod 7 drives the striking plate 8 to reciprocate and beat the adjacent bags. At the same time, when the bag moves below the baffle 10, the suction cup 11 and suction cup 22 at the bottom of the baffle 10 start to work. The suction cup 11 sucks the opening of the bag and the suction cup 22 sucks the tail of the bag. After the suction cup 11 sucks the opening of the bag, the clamping plate 13 at the top of the baffle 10 moves downward and clamps the opening of the bag. Since the opening of the bag is sucked by the suction cup 11 and the clamping plate 13 applies clamping force, the bag is stably fixed and in an open state, ensuring the efficient and stable operation of the valve bag automatic bag injection machine.

[0048] Furthermore, the outer rear side of the fixed rod 201 is connected to the outer rear side of the outer frame 1, and the connecting shell 202 on the right side of its outer wall is connected to the fixed block 204 by means of the connecting rod 203. During operation, the fixed rod 201 forms a fixed frame by relying on its connection with the outer frame 1. The connecting shell 202 and the connecting rod 203 transmit the external force on the fixed block 204 to the fixed rod 201 and the outer frame 1, thereby ensuring that the fixed block 204 can maintain stability.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
