Description

Technical Field

[0001] This invention relates to the structure of a movable conveyor frame, and more particularly to the frame mechanism of a packing machine. Background Technology

[0002] A strapping machine is a machine that uses strapping tape to bundle items. The frame device is a guide and support device for the strapping tape before it is bundled. One type of frame device uses a combination of a movable frame and a fixed frame. The tape path has a groove-shaped cross-section. The tape path and the movable frame are fixed together, with the opening of the groove facing the fixed frame. Just before the tape retracts, the movable frame moves rapidly away from the fixed frame, and the entire tape path moves rapidly along with the movable frame, thus opening the tape path and allowing the strapping tape to be retracted and wrapped around the bundled item. The strapping machine frame performs this movement very quickly, and the strapping tape, originally threaded within the tape path, may be pulled off course or misaligned by this movement, affecting the packaging quality. Summary of the Invention

[0003] The purpose of this invention is to provide a packaging machine frame mechanism that avoids the shortcomings mentioned in the background art and improves packaging quality. To this end, this invention adopts the following technical solution:

[0004] A baling machine frame mechanism includes a fixed frame and a conveyor belt. The conveyor belt is characterized by being composed of an inner movable conveyor belt and an outer fixed conveyor belt. The baling machine frame mechanism also includes an inner movable conveyor belt opening and closing motion drive mechanism and an inner movable conveyor belt opening and closing guide mechanism. The outer fixed conveyor belt is mounted on the fixed frame. The inner movable conveyor belt is connected to the inner movable conveyor belt opening and closing motion drive mechanism and the inner movable conveyor belt opening and closing guide mechanism, and can be driven to move back and forth to complete the opening and closing of the conveyor belt.

[0005] The opening and closing motion drive mechanism includes a first side drive mechanism, a second side drive mechanism, and a synchronization mechanism. The first side drive mechanism and the second side drive mechanism are located on the left and right sides of the inner ring movable belt, respectively. The first side drive mechanism and the second side drive mechanism perform lifting and lowering movements synchronously based on the synchronization mechanism. The two sides of the inner ring movable belt are movably connected to the first side drive mechanism and the second side drive mechanism, respectively.

[0006] Based on the above technical solutions, the present invention can also employ the following further technical solutions, or combine these further technical solutions:

[0007] The synchronization mechanism includes a connecting mechanism and a driving mechanism. The first side driving mechanism is connected to the driving mechanism and is driven to perform lifting and lowering movements. The second side driving mechanism and the first side driving mechanism are connected through the connecting mechanism and can lift and lower synchronously with the first side driving mechanism.

[0008] The inner ring movable guide includes an inner ring wall and a first side wall of the guide; the outer ring fixed guide is provided with an outer ring wall of the guide.

[0009] The fixed frame is equipped with a panel, and the outer ring fixed belt is connected to the panel, the panel forming the second sidewall of the belt.

[0010] The inner ring movable belt is a single piece; the outer ring fixed belt is a single piece.

[0011] The connecting mechanism between the second-side drive mechanism and the first-side drive mechanism is a connecting rope; a guide wheel for the connecting rope is provided on the fixed frame.

[0012] The upper end of the first side drive mechanism is connected to a connecting rope. The connecting rope first goes downward, then turns through the first guide wheel to be close to the panel on the fixed frame and upward, then turns through the second guide wheel to be above the outer ring fixed track and towards the side where the second side drive mechanism is located, and then turns downward through the third guide wheel above the second side drive mechanism and connects to the second side drive mechanism.

[0013] The drive mechanism of the first side drive mechanism adopts a cam-controlled linkage mechanism, including a transverse link. The transverse link transmits power from the middle of the packing machine to the lower part of the first side drive mechanism. One end of the transverse link is fixedly connected to a swing arm, which cooperates with the cam and can be driven to rotate by the cam, thereby driving the transverse link to rotate. The other end of the transverse link is fixedly connected to an output linkage mechanism, which is then connected to the first side drive mechanism to drive the inner ring movable belt to move in the opening direction.

[0014] The inner ring movable belt opening and closing motion drive mechanism includes a drive elastic component that drives the inner ring movable belt to move in the closing direction.

[0015] The first side drive mechanism and the inner ring movable belt are connected by an opening and closing control component, and the second side drive mechanism and the inner ring movable belt are connected by a lifting guide component; the first side drive mechanism and the fixed frame are connected by a lifting guide component; the first side drive mechanism and the second side drive mechanism also include an extended connecting rod.

[0016] The opening and closing control assembly includes an inclined groove and a guide fitting that mates with the inclined groove wall, and the lifting guide assembly includes a vertical groove and a guide fitting that mates with the vertical groove wall.

[0017] The outer ring wall of the outer ring fixed track includes a left outer ring wall, an upper outer ring wall, and a right outer ring wall. The side of the left outer ring wall, the upper outer ring wall, and the right outer ring wall facing the inner ring track wall has a recessed area.

[0018] The inner ring movable belt opening and closing guide mechanism adopts a guide column, which is fixed to a fixed frame or a component fixed together with the fixed frame. The inner ring movable belt is provided with a guide structure, and the guide column passes through the guide structure.

[0019] By adopting the technical solution of the present invention, the present invention can reduce the impact of the opening action of the packing strap on the packing strap, and can reduce the weight that needs to be moved when opening the packing strap, reduce the power requirements, and improve the overall integrity and synchronization of the opening and closing actions, making it more stable and improving the binding quality.

[0024] Figure 5 A schematic diagram of the inner activity area. Detailed Implementation

[0025] Referring to the attached drawings, the baling machine frame mechanism includes a fixed frame 100 and a conveyor belt. The conveyor belt consists of an inner movable conveyor belt 200 and an outer fixed conveyor belt 1. The baling machine frame mechanism also includes an inner movable conveyor belt opening and closing motion drive mechanism and an inner movable conveyor belt opening and closing guide mechanism. Compared with conventional baling machines, the load on the inner movable conveyor belt opening and closing motion drive mechanism, at least for the conveyor belt portion, is reduced.

[0026] The outer ring fixed guide 1 is mounted on the fixed frame 100. The inner ring movable guide 200 is connected to the inner ring movable guide opening and closing motion drive mechanism and the inner ring movable guide opening and closing guide mechanism, and can move back and forth relative to the front panel 101 of the fixed frame 100 to complete the opening and closing of the guide.

[0027] When the inner movable belt 200 moves into position towards the front panel 101 of the fixed frame 100, the belt formed by the inner movable belt 200 and the outer fixed belt 1 closes. When the inner movable belt 200 moves away from the front panel 101 of the fixed frame, the belt opens.

[0028] The inner movable belt channel 200 and the outer fixed belt channel 1 are integral components. The inner movable belt channel 200 has an approximate L-shaped cross-section. When the belt channel is closed, the integral component forms the inner ring wall 2 and the side wall 20 away from the front panel of the fixed frame. No further reshaping is required during installation.

[0029] The outer ring fixing channel 1 is a single piece. When the channel is closed, the outer ring fixing channel forms the outer ring wall of the channel. The outer ring fixing channel is connected to the front panel 101 of the fixing frame by screws, and no further straightening is required during installation. When the outer ring fixing channel is set on the fixing frame, it can also be welded to the fixing frame or be an integral part of the fixing frame.

[0030] As shown in the figure, the outer ring wall of the outer ring fixing channel 1 includes a left outer ring wall 11, an upper outer ring wall 12, and a right outer ring wall 13. A recessed area 10 is provided on the side of the left outer ring wall 11, the upper outer ring wall 12, and the right outer ring wall 13 facing the inner ring channel wall. This recessed area 10 can prevent or alleviate the lateral pulling of the channel during opening caused by the wavy shape that may be formed by the packing strap during the feeding process, which results in the outer ring wall being connected to the inner ring channel wall by the packing strap with a certain degree of rigidity. It can serve as a substitute for the ejector pin. For the integral outer ring fixing channel 1, forming this recessed area 10 is easier, and the connection of the recessed area 10 is smoother, improving the application effect of the recessed area 10. The outline of the recessed area 10 can be an arc or an elliptical arc, and the recessed area 10 smoothly transitions to the straight edge of the outer ring channel wall.

[0031] The opening and closing motion drive mechanism includes a first side drive mechanism, a second side drive mechanism, and a synchronization mechanism. The first side drive mechanism and the second side drive mechanism are located on the left and right sides of the inner ring movable belt 200, respectively. The first side drive mechanism and the second side drive mechanism perform lifting and lowering movements synchronously based on the synchronization mechanism. The two sides of the inner ring movable belt 200 are movably connected to the first side drive mechanism and the second side drive mechanism, respectively.

[0032] The synchronization mechanism can employ a scheme where the first and second side drive mechanisms are driven separately, and the power sources within them are simultaneously started and stopped by a control mechanism, thereby enabling the two sides of the inner ring movable belt to move synchronously back and forth. The power source can be a cylinder, a motor, or a suction cylinder or linkage mechanism combined with a return spring; the power source can be located between the inner ring movable belt and the fixed frame.

[0033] In this embodiment, the synchronization mechanism adopts a mechanical series structure. The synchronization mechanism includes a connecting mechanism and a driving mechanism. The lower end of the first side driving mechanism is connected to the driving mechanism and can be driven to perform lifting and lowering movements. The upper end of the second side driving mechanism is connected to the upper end of the first side driving mechanism through the connecting mechanism and can lift and lower synchronously with the first side driving mechanism. The two sides of the inner ring movable belt 200 are respectively connected to the first side driving mechanism and the second side driving mechanism through connecting members.

[0034] The connecting mechanism between the second-side drive mechanism and the first-side drive mechanism is a connecting rope 7, and the second-side drive mechanism and the first-side drive mechanism are respectively provided with rope connectors 90; the fixed frame 100 is provided with guide wheels for the connecting rope. In this embodiment, the connecting mechanism further adopts the following structure: the upper end of the first-side drive mechanism is connected to the connecting rope 7, the direction of the connecting rope 7 is first downward, then turned by the first guide wheel 71 to be close to the front panel 101 on the fixed frame and upward, then turned by the second guide wheel 72 to be above the outer ring fixed track 1 and facing the second side, and above the second-side drive mechanism by the third guide wheel 73 to be downward and connected to the second-side drive mechanism. In addition, other connecting rope guide wheels can also be provided at appropriate positions.

[0035] In addition, the connecting mechanism can also be implemented using linkage mechanisms or other methods.

[0036] The drive mechanism of the first side drive mechanism can be a linkage mechanism controlled by cam 8, and the rotational power of cam 8 can be derived from the core motor 300 of the packing machine. In this embodiment, the drive mechanism can be implemented as follows: it includes a transverse link 80, which transmits power from the middle of the packing machine to the lower part of the first side drive mechanism. One end of the transverse link 80 is fixedly connected to a rocker arm 81, which cooperates with a cam 8 and can be driven to rotate by the cam 8, thereby driving the transverse link 80 to rotate. The end of the rocker arm 81 can be provided with a roller for cooperating with the cam 8. The other end of the transverse link 80 is fixedly connected to an output linkage mechanism 82, which is then connected to the first side drive mechanism. When the transverse link 80 is driven to rotate by the rocker arm 81, it drives the output linkage mechanism 82 to rotate, thereby driving the first side drive mechanism to rise, thus causing the inner ring movable belt 200 to move in the opening direction. The inner ring movable belt opening and closing motion drive mechanism also includes a drive elastic component 5, which drives the inner ring movable belt 200 to move in the closing direction.

[0037] The first side drive mechanism is connected to the inner ring movable belt 200 and the second side drive mechanism is connected to the inner ring movable belt through an opening and closing control component. The first side drive mechanism is connected to the fixed frame and the second side drive mechanism is connected to the fixed frame 100 through a lifting guide component. The first side drive mechanism and the second side drive mechanism also include a connecting rod 9 with an extended length.

[0038] In this embodiment, the opening and closing control component includes a sloping groove 91 and a guide roller 92 that cooperates with the sloping groove wall. This component can also be replaced by a cam control mechanism. The lifting guide component includes a vertical groove 93 and a guide roller 94 that cooperates with the vertical groove wall. This component can also be replaced by other mechanisms such as guide rails and sliders. The sloping groove 91 and the vertical groove 93 can be located in the first side drive mechanism and the second side drive mechanism. The roller 92 can be disposed on the inner ring movable belt, and the roller 94 can be disposed on the fixed frame 100.

[0039] The inner ring movable belt track opening and closing guide mechanism adopts a guide post 4, which is fixed on the fixed frame 100. The inner ring movable belt track 200 is provided with a guide structure, which can be a guide sleeve 201, a guide hole, etc., and the guide post 4 passes through the guide structure. The driving elastic component 5 is sleeved on the outside of the guide post 4 and is located between the end of the guide post and the inner ring movable belt track 200.

[0040] The above description is only a specific embodiment of the present invention, but the structural features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the protection scope of the present invention.
