Description

Technical Field

[0001] The utility model relates to a bag pushing mechanism for a stacking machine. Background Art

[0002] After being vacuum-packed in bags, powders and granules such as grains, feeds, salt, seeds, milk powder, etc. need to be stacked. Currently in the market, most vacuum packages are packed in cartons. In order to save the packaging cost, a packaging method using heat shrinkable films has gradually emerged in the market, which can basically meet the transportation and storage requirements like carton packaging and greatly reduce the cost at the same time. Currently, stacking usually relies on manual labor. With the market demand, relying solely on manual stacking has the following disadvantages: 1. The efficiency of manual stacking is slow and cannot meet the current market demand; 2. Manual stacking is uneven, resulting in inconvenience for subsequent packaging. Therefore, the demand for high-speed stacking machines in the packaging industry is increasing day by day. Before stacking, it is necessary to transfer and push the material bags. Currently, the existing pushing often has problems such as incomplete pushing or excessive pushing, which causes the position of the material bags to shift and affects the subsequent stacking effect, and thus needs to be improved urgently. Content of the Utility Model

[0003] In view of the deficiencies of the prior art, the technical problem to be solved by the utility model is to provide a bag pushing mechanism for a stacking machine, which is not only reasonable in structure but also stable and convenient.

[0004] To solve the above technical problem, the technical solution of the utility model is: a bag pushing mechanism for a stacking machine, including a main frame. A bag pushing conveyor belt is arranged inside the main frame. Above the bag pushing conveyor belt, there is a bag pushing frame that slides longitudinally. A lifting cylinder is fixedly connected to the bag pushing frame, and the bottom of the telescopic end of the lifting cylinder is fixedly provided with a bag pushing plate. The bag pushing frame is driven to reciprocate by a horizontal bag pushing cylinder. At the end of the pushing of the bag pushing plate, there is a bag taking-out mechanism for receiving or taking out the bag. The bag taking-out mechanism includes a horizontal support plate. Both sides of the support plate are slidably connected to the main frame through connecting seats. The support plate is driven by a bag taking-out cylinder arranged parallel to the bag pushing cylinder. Above the end of the pushing of the bag pushing cylinder on the main frame, there is an overshoot baffle for blocking the excessive pushing of the material bag or blocking the material bag from being linked by the support plate when taking out the bag.

[0005] Furthermore, a bag blocking plate is arranged along the transverse conveying direction of the bag pushing conveyor belt, and the top of the bag blocking plate is driven to lift vertically by a bag blocking cylinder.

[0006] Furthermore, there are two groups of the bag pushing conveyor belts and they are horizontally butted. At the near ends of the transverse two sides of the corresponding bag pushing frames, lifting cylinders are fixedly provided respectively to push the material bags on the two bag pushing conveyor belts. The bag pushing cylinder extends longitudinally, and its telescopic end is fixedly connected to the middle of the bag pushing frame. Both transverse ends of the bag pushing frame are slidably connected to a bag pushing slide rail through sliders, and the bag pushing slide rails are fixedly connected to the main frame.

[0007] Further, there are two groups of the baffle plates corresponding to the bag blocking cylinders, which are respectively arranged above the input ends of the two bag pushing conveyors to prevent subsequent material bags from being input together.

[0008] Further, the overshoot baffle plates both extend horizontally and are symmetrically arranged in two groups. The two overshoot baffle plates are fixedly connected into one body by a horizontal connecting plate. The middle of the horizontal connecting plate is penetrated by a longitudinal lead screw and is driven to slide longitudinally by it. Both ends of the horizontal connecting plate are slidably connected to a longitudinal adjusting slide rail through sliders, and the adjusting slide rail is fixedly connected to the main frame.

[0009] Further, there are two groups of the support plates symmetrically arranged. The two groups of support plates are fixedly connected by a linkage plate. The telescopic end of the bag extracting cylinder is hinged to the linkage plate. The tops of the connecting seats are both slidably connected to a longitudinal slide rail fixedly connected to the main frame through sliders.

[0010] Further, a stacking table for receiving material bags for stacking is arranged below the support plate.

[0011] Further, the ends of the lead screws are both rotatably connected to the main frame through bearing seats, and one end penetrates out of the bearing seat and is fixedly connected with a crank.

[0012] Compared with the prior art, the utility model has the following beneficial effects: Through the setting of the overshoot baffle plates, it is possible to avoid both the problem of excessive pushing of the material bags during bag pushing and the problem of the material bags being displaced by the support plate during bag extraction. At the same time, the adjusting assembly can be adaptively adjusted to fit various types of material bags, with strong applicability, simple structure, and stable and efficient cooperation.

Specific implementation mode

[0020] To make the above features and advantages of the present utility model more obvious and understandable, specific embodiments are hereinafter given and described in detail in conjunction with the accompanying drawings as follows.

[0021] As Figures 1 to 5 shown, a pushing mechanism for a bag stacking machine includes a main frame 1. A pushing conveyor belt 2 is arranged inside the main frame. Above the pushing conveyor belt, there is a pushing frame 3 that slides longitudinally. A lifting cylinder 4 is fixedly connected to the pushing frame. At the bottom of the telescopic end of the lifting cylinder, a pushing plate 5 is fixedly provided. The pushing frame is driven to reciprocate by a horizontal pushing cylinder 6. At the end of the pushing of the pushing plate, there is a bag extraction mechanism 7 for receiving the material bag or extracting the bag. The bag extraction mechanism includes a horizontal support plate 8. Both sides of the support plate are slidably connected to the main frame through connecting seats 9. The support plate is driven by a bag extraction cylinder 10 arranged parallel to the pushing cylinder. Above the end of the pushing of the pushing cylinder on the main frame, there is an overshoot baffle 11 for blocking the over-pushing of the material bag during pushing or blocking the material bag from being driven by the support plate during bag extraction.

[0022] In the embodiment of the present utility model, a pushing assembly is composed of a pushing frame, a lifting cylinder, a pushing plate, a pushing cylinder, and a pushing slide rail, and an adjusting assembly is composed of a lead screw, an overshoot baffle, a transverse connecting plate, an adjusting slide rail, a bearing seat, and a crank.

[0023] In the embodiment of the present utility model, a bag blocking plate 12 is arranged along the transverse conveying direction of the pushing conveyor belt. The top of the bag blocking plate is driven to lift vertically by a bag blocking cylinder 13.

[0024] In the embodiment of the present utility model, two groups of pushing conveyor belts are arranged and are horizontally butted. At the near ends of the transverse two sides of the corresponding pushing frame, lifting cylinders are fixedly provided to push the material bags on the two pushing conveyor belts respectively. The pushing cylinder extends longitudinally, and its telescopic end is fixedly connected to the middle of the pushing frame. Both transverse ends of the pushing frame are slidably connected to the pushing slide rails 14 through sliders, and the pushing slide rails are fixedly connected to the main frame.

[0025] In the embodiment of the present utility model, two groups of the baffle plates and the bag blocking cylinders are correspondingly arranged, and are respectively arranged above the input ends of the two pushing conveyor belts to prevent subsequent material bags from being input together.

[0026] In the embodiment of the present utility model, the overshoot baffles all extend horizontally and are symmetrically arranged in two groups. The two overshoot baffles are fixedly connected into an integral body by a transverse connecting plate 15. The middle of the transverse connecting plate is penetrated by a longitudinal lead screw 16 and is driven to longitudinally slide by the lead screw. Both ends of the transverse connecting plate are slidably connected to a longitudinal adjusting slide rail 17 through sliders, and the adjusting slide rail is fixedly connected to the main frame.

[0027] In the embodiment of the present utility model, the support plates are symmetrically arranged in two groups. The two support plates are fixedly connected by a linkage plate 18. The telescopic end of the bag-pulling cylinder is hinged to the linkage plate. The tops of the connecting seats are slidably connected to a longitudinal slide rail 19 fixedly connected to the main frame through sliders.

[0028] In the embodiment of the present utility model, a stacking table 20 for receiving and stacking the material bags is arranged below the support plate.

[0029] In the embodiment of the present utility model, the ends of the lead screws are rotatably connected to the main frame through bearing seats 21, and a crank 22 is fixedly connected to one end after passing through the bearing seat.

[0030] In the embodiment of the present utility model, first, after the specification of the material bag is selected, the position of the overshoot baffle needs to be adjusted by manually shaking the crank. When the material bags are respectively conveyed onto the two pushing conveyor belts, the bag-blocking cylinder descends, and the pushing conveyor belt stops conveying. Blocked by the bag-blocking plate, then the lifting cylinder descends, and the pushing plate abuts against the edge of the material bag. Then the pushing cylinder contracts to drive the pushing plate to longitudinally push the material bag onto the support plate, and the overshoot baffle blocks to prevent excessive longitudinal pushing and dropping. Finally, the bag-pulling cylinder contracts and drives the support plate to longitudinally slide, so that the material bag does not move with the support plate under the blocking action of the overshoot baffle, and the material bag freely falls onto the stacking table for stacking after the support plate moves.

[0031] The present utility model is not limited to the above best embodiment, and anyone can obtain other various forms of the pushing mechanism for the stacking machine under the inspiration of the present utility model. All equal changes and modifications made according to the scope of the patent application of the present utility model shall fall within the coverage scope of the present utility model.
