Description

Technical Field

[0001] This utility model relates to the field of ton bag machine feeding technology, specifically an automatic lifting device for the feeding port of a ton bag machine. Background Technology

[0002] A ton bag packaging machine is a large-scale automated packaging equipment used for packaging materials in ton bags. It is mainly used in industries such as chemicals, building materials, grains, feed, and mining. Through automatic weighing, filling, and sealing processes, it loads powdery, granular, or flake materials into ton bags, achieving efficient and precise packaging operations. The automatic lifting device at the ton bag machine's feeding port is an important auxiliary device. Its main function is to automatically adjust the height of the feeding port. This device uses mechanical transmission or a hydraulic system to change the height of the feeding port, ensuring it maintains a suitable docking height with different material conveying equipment (such as screw conveyors, belt conveyors, and pneumatic conveying devices).

[0003] In the prior art, when feeding powder into the feed port of a ton bag machine, the powder may clump together. Because the clumps cannot be broken up or the feed port cannot be cleared, the feed port is prone to blockage, which will affect the continuity of feeding and is not conducive to ensuring feeding efficiency. Therefore, in order to solve the above problems, an automatic lifting device for the feed port of the ton bag machine is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic lifting device for the feeding port of a ton bag machine, so as to solve the problem mentioned in the background art that the feeding port is easily blocked due to the inability to properly disperse clumps of powder or clear the feeding port, which in turn affects the continuity of feeding and is not conducive to ensuring feeding efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic lifting device for the loading port of a ton bag machine, including a bracket, a loading pipe movably disposed on the inner side of the bracket, and a connecting plate fixedly connected to the surface of the loading pipe, a guide rail fixedly connected to the upper surface of the bracket, a lifting component fixedly connected to the surface of the loading pipe, and the lifting component movably disposed on the surface of the guide rail, and a telescopic cylinder movably mounted on the surface of the bracket, with the end of the telescopic cylinder away from the bracket movably connected to the lifting component;

[0006] The inner side of the bracket is provided with a feeding mechanism, and the surface of the connecting plate is provided with a striking mechanism.

[0007] The feeding mechanism includes a rotating rod and a stirring rod, both of which are movable inside the feeding pipe. The striking mechanism includes a movable rod and a striking block. The movable rod is arranged in two groups and is movable on the top of the connecting plate, and the striking block is fixedly connected to the surface of the movable rod.

[0008] Preferably, the feeding mechanism further includes a support frame, which is fixedly connected to the top end of the feeding pipe. The rotating rod is movable inside the support frame, and a first motor is fixedly installed at the top end of the support frame. The rotating rod and the output end of the first motor are fixedly connected.

[0009] Preferably, the stirring rods are arranged in sixteen groups and fixedly connected to the connecting plate. The surface of the rotating rod is fixedly connected to a fixing rod, and the surface of the fixing rod is fixedly connected to a brush plate. Both the fixing rod and the brush plate are movable inside the feeding pipe.

[0010] Preferably, a limiting rod is fixedly connected to the bottom end of the support frame, a connecting block is fixedly connected to the surface of the rotating rod, and a rotating groove is provided on the inner side of the connecting block. The end of the limiting rod away from the support frame moves within the rotating groove.

[0011] Preferably, the striking mechanism further includes a fixing plate, which is fixedly connected to the upper surface of the connecting plate. A reciprocating lead screw is movably connected to the inner side of the fixing plate, and a second motor is fixedly installed at the top of the fixing plate. One end of the reciprocating lead screw is movably connected to the connecting plate, and the other end of the reciprocating lead screw is fixedly connected to the output end of the second motor.

[0012] Preferably, a movable block is movably connected to the surface of the reciprocating lead screw, and the movable block moves on the surface of the fixed plate, and a support block is fixedly connected to the upper surface of the bracket.

[0013] Preferably, the movable rod is movably connected to the support block via a rotating shaft, and a spring is fixedly connected to the bottom end of the movable rod. One end of the spring is fixedly connected to the connecting plate, and the other end of the spring is fixedly connected to the movable rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The rotation of the rotating rod drives the stirring rod and the fixing rod to rotate as well. The rotation of the stirring rod can agitate the powder entering the feeding pipe, which can break up the clumps of powder and prevent the powder from accumulating and clogging in the feeding pipe, thus ensuring the stability and continuity of feeding. The rotation of the fixing rod can drive the brush plate to rotate as well. The brush plate can clean the inner wall of the feeding pipe, which can prevent the powder from adhering and thus better avoid the accumulation of powder, making it easier for the powder to fall.

[0016] 2. By rotating the reciprocating screw, the movable block can reciprocate vertically under the action of the reciprocating screw, and can squeeze the movable rod. Combined with the elasticity of the spring, the movable rod can drive the striking block to move accordingly, so that the striking block can strike the feeding pipe. The vibration generated by the striking can better prevent the powder from adhering to the feeding pipe, thereby further reducing accumulation. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-5 One embodiment provided by this utility model:

[0025] The telescopic cylinder 15, the first motor 22, and the second motor 32 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0026] An automatic lifting device for the loading port of a ton bag machine includes a support 1. A loading pipe 11 is movably mounted on the inner side of the support 1, and a connecting plate 12 is fixedly connected to the surface of the loading pipe 11. A guide rail 13 is fixedly connected to the upper surface of the support 1. A lifting assembly 14 is fixedly connected to the surface of the loading pipe 11 and is movably mounted on the surface of the guide rail 13. A telescopic cylinder 15 is movably mounted on the surface of the support 1, and the end of the telescopic cylinder 15 furthest from the support 1 is movably connected to the lifting assembly 14. A feeding mechanism is provided on the inner side of the support 1. The surface of 2 is provided with a striking mechanism. The feeding mechanism includes a rotating rod 21 and a stirring rod 23. Both the rotating rod 21 and the stirring rod 23 are movable inside the feeding pipe 11. The striking mechanism includes a movable rod 35 and a striking block 36. The movable rod 35 is in two sets and is movable on the top of the connecting plate 12. The striking block 36 is fixedly connected to the surface of the movable rod 35. Through the extension and retraction of the telescopic cylinder 15, in conjunction with the setting of the lifting component 14, the feeding pipe 11 can be moved vertically, thereby facilitating the lifting and lowering of the feeding pipe 11 and changing the feeding position.

[0027] Furthermore, the feeding mechanism also includes a support frame 2, which is fixedly connected to the top of the feeding pipe 11. The rotating rod 21 is movable inside the support frame 2. The top of the support frame 2 is fixedly installed with a first motor 22, and the output end of the rotating rod 21 and the first motor 22 are fixedly connected. By setting the rotating rod 21, when the rotating rod 21 rotates, the stirring rod 23 can move accordingly. The rotation of the stirring rod 23 can agitate the powder entering the feeding pipe 11, break up the clumps of powder, and prevent the feeding pipe 11 from getting blocked, thus ensuring stable feeding.

[0028] Furthermore, the stirring rods 23 are fixedly connected to the connecting plate 12 in sixteen groups. The surface of the rotating rod 21 is fixedly connected to the fixing rod 24, and the surface of the fixing rod 24 is fixedly connected to the brush plate 25. Both the fixing rod 24 and the brush plate 25 are movable inside the feeding pipe 11. By setting the fixing rod 24, when the rotating rod 21 rotates, the fixing rod 24 can drive the brush plate 25 to rotate accordingly. The rotation of the brush plate 25 can scrape the wall of the feeding pipe 11, which can prevent the accumulation of coal powder.

[0029] Furthermore, a limiting rod 26 is fixedly connected to the bottom end of the support frame 2, and a connecting block 27 is fixedly connected to the surface of the rotating rod 21. A rotating groove 28 is opened on the inner side of the connecting block 27. The end of the limiting rod 26 away from the support frame 2 moves inside the rotating groove 28. By setting the limiting rod 26 and opening the rotating groove 28, the rotating rod 21 can be limited, so that the rotating rod 21 can rotate stably.

[0030] Furthermore, the striking mechanism also includes a fixed plate 3, which is fixedly connected to the upper surface of the connecting plate 12. A reciprocating screw 31 is movably connected to the inner side of the fixed plate 3, and a second motor 32 is fixedly installed at the top of the fixed plate 3. One end of the reciprocating screw 31 is movably connected to the connecting plate 12, and the other end of the reciprocating screw 31 is fixedly connected to the output end of the second motor 32. By rotating the reciprocating screw 31, the movable block 33 can be driven to reciprocate. With the setting of the spring 37, the movable rod 35 can move and reset under the action of the movable block 33 and the spring 37, thereby enabling the striking block 36 to strike the feeding pipe 11. The vibration generated by the striking can prevent coal powder from adhering to the inner wall of the feeding pipe 11.

[0031] Furthermore, a movable block 33 is movably connected to the surface of the reciprocating screw 31, and the movable block 33 moves on the surface of the fixed plate 3. A support block 34 is fixedly connected to the upper surface of the bracket 1. With the movable block 33, when the reciprocating screw 31 rotates, the movable block 33 can move vertically on the surface of the fixed plate 3, which facilitates the movable block 33 to squeeze the movable rod 35 during the descent, thereby enabling the movable rod 35 to drive the striking block 36 to move.

[0032] Furthermore, the movable rod 35 is movably connected to the support block 34 via a rotating shaft. A spring 37 is fixedly connected to the bottom end of the movable rod 35. One end of the spring 37 is fixedly connected to the connecting plate 12, and the other end of the spring 37 is fixedly connected to the movable rod 35. By setting the spring 37, the movable rod 35 can be reset, thereby enabling the striking block 36 to be reset.

[0033] Working principle: During use, the first motor 22 is electrically connected to an external power source. The operator starts the first motor 22 by pressing the switch. The first motor 22 drives the rotating rod 21 to rotate. The connecting block 27 will rotate under the action of the rotating rod 21, and the limiting rod 26 will move inside the rotating groove 28. The stirring rod 23 and the fixing rod 24 will rotate under the action of the rotating rod 21. The rotation of the stirring rod 23 can agitate the powder entering the feeding pipe 11, break up the clumps of powder, and prevent and clear the feeding pipe 11. The brush plate 25 will rotate under the action of the fixing rod 24, which can clean the inner wall of the feeding pipe 11, thereby preventing the powder from adhering to and accumulating on the inner wall of the feeding pipe 11.

[0034] The second motor 32 is electrically connected to an external power source. The operator starts the second motor 32 by pressing a switch. The operation of the second motor 32 drives the reciprocating screw 31 to rotate. The movable block 33 moves on the surface of the second motor 32 and the fixed plate 3 under the action of the reciprocating screw 31, realizing the vertical movement of the movable block 33. The descent of the movable block 33 compresses the movable rod 35, and then the movable rod 35 moves through the rotating shaft, causing the striking block 36 to lift up. At this time, the spring 37 is in a contracted state, so that the striking block 36 strikes the feed tube 11. When the movable block 33 moves up and releases the compression on the movable rod 35, the movable rod 35 is reset under the rebound action of the spring 37, and then the striking block 36 is reset accordingly.

[0035] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
