A frame structure of a bag arranging machine

Abstract

A bag arranging machine frame structure belongs to the technical field of packaging equipment. It includes a first mounting frame, a second mounting frame, and a guiding device connecting the two. The first mounting frame and the second mounting frame are driven to move apart or together along the guiding device, and corresponding locking devices are provided on both the first mounting frame and the second mounting frame. In the present invention, by driving the first mounting frame and the second mounting frame to separate along the guiding device, the distance between the first rotating shaft and the second rotating shaft is increased to form an operating space without the need for disassembly, reducing the operation difficulty during maintenance and repair operations. At the same time, the locking device can prevent the first rotating shaft or the second rotating shaft from rotating through friction, so that the first rotating shaft and the second rotating shaft maintain the state before separation, avoiding the misalignment of the blade structures on the first rotating shaft and the second rotating shaft, and further preventing the first mounting frame and the second mounting frame from being unable to work after they are joined together.

Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and particularly to a frame structure of a bag arranging machine. Background Art

[0002] A bag arranging machine, namely a packaging and sorting device; in the prior art, a bag arranging machine used to change the vertically falling packaging bags into a horizontal state for stacking is provided with symmetrically arranged and relatively rotatable rotating shafts on a frame, and a blade structure arranged on the rotating shafts and rotating around the rotating shafts. The rotating shafts are perpendicular to the falling direction of the packaging bags. The blade structure has a plurality of claws, and the accommodating space between two adjacent claws is used to accommodate the falling packaging bags. When the packaging bags fall, the packaging bags are accommodated in the accommodating space between two adjacent claws. While the blade structure rotates, the packaging bags are changed from the original vertical state to a horizontal state. After the blade structure continues to rotate, the packaging bags are placed into the stacking space; however, in the existing structure, the positions of the two rotating shafts are fixed, and the gap between the two blade structures in the radial direction of the rotating shafts is very small, close to the contacting state, which makes the space between the two rotating shafts very narrow. When the situation that the packaging bags are stuck or misaligned in the accommodating space between the two claws occurs, or when maintenance and repair of the bag arranging machine are required, or parts are inspected and replaced, the bag arranging machine can only be disassembled, and at least one rotating shaft and the blade structure thereon need to be removed to enable the bag arranging machine to have the operating space for adjusting and taking out the above-mentioned packaging bags, maintaining and repairing, and inspecting and replacing parts. However, the above method requires the disassembly of the bag arranging machine, resulting in cumbersome and difficult operations. Moreover, after disassembly and assembly, the accommodating spaces of the two blade structures respectively used to accommodate the packaging bags need to be made corresponding to ensure that it can perform the bag arranging work, which further increases the difficulty of disassembly and assembly operations, causing the problem of cumbersome and difficult operations. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect that in the bag arranging machine of the prior art, due to the fixed positions of the rotating shafts and the very narrow space between the two rotating shafts, when maintenance and repair operations are required, the bag arranging machine must be disassembled, and after disassembly and assembly, the accommodating spaces of the two blade structures respectively used to accommodate the packaging bags need to be made corresponding, resulting in cumbersome and difficult operations, so as to provide a frame structure of a bag arranging machine.

[0034] The technical solution of the present invention has the following advantages:

[0035] 1. The frame structure of the bag arranging machine provided by the present invention includes a first mounting frame adapted to be provided with a rotatable first rotating shaft; a second mounting frame adapted to be provided with a rotatable second rotating shaft, and the second rotating shaft is parallel to the first rotating shaft; a guiding device connecting the first mounting frame and the second mounting frame; one of the first mounting frame and the second mounting frame is driven to move along the guiding device towards or away from the other of the first mounting frame and the second mounting frame, so that the first rotating shaft and the second rotating shaft move towards or away from each other; a locking device, and corresponding locking devices are provided on both the first mounting frame and the second mounting frame. The locking device includes: a friction belt adapted to abut against the first rotating shaft or the second rotating shaft to provide a frictional force to prevent the first rotating shaft or the second rotating shaft from rotating; a driving part driving the friction belt towards or away from the first rotating shaft, or towards or away from the second rotating shaft.

[0036] The present invention provides a first mounting frame and a second mounting frame connected by a guiding device. The first mounting frame and the second mounting frame can be driven to separate or combine along the guiding device, so that the first rotating shaft and the second rotating shaft move towards or away from each other. When the packaging bag gets stuck or misaligned in the accommodation space between the two clamping jaws, or when maintenance and repair of the bag arranging machine are required, or when parts are inspected, repaired or replaced, the first mounting frame and the second mounting frame can be driven to separate, driving the first rotating shaft and the second rotating shaft away from each other, thereby increasing the distance between the first rotating shaft and the second rotating shaft to form an operation space, without removing the first rotating shaft and / or the second rotating shaft, reducing the operation difficulty during maintenance and repair operations, and improving the work efficiency. At the same time, the present invention is provided with a locking device, which can drive the friction belt to abut against the corresponding first rotating shaft or second rotating shaft through the driving part, thereby preventing the first rotating shaft or the second rotating shaft from rotating through the frictional force. When the first mounting frame and the second mounting frame are separated, the first rotating shaft and the second rotating shaft are kept in the state before separation through the locking device, avoiding rotation during separation and maintenance and repair operations, resulting in misalignment of the blade structures on the first rotating shaft and the second rotating shaft, and further causing the inability to work after the first mounting frame and the second mounting frame are combined.

[0037] 2. The frame structure of the bag arranging machine provided by the present invention, the friction belt is bent to form a bent portion, the bent portion is adapted to abut against the outer periphery of the first rotating shaft or the second rotating shaft, the friction belt includes a fixed end connected to the first mounting bracket or the second mounting bracket, and a movable end connected to the driving portion; the driving portion includes a stretching member, which is movably connected to the first mounting bracket or the second mounting bracket along a direction perpendicular to the axial direction of the first rotating shaft or the second rotating shaft, and the stretching member connects the movable end and drives the movable end to move, so that the bent portion moves towards or away from the first rotating shaft, or, towards or away from the second rotating shaft.

[0038] The friction belt of the present invention is bent to form a bent portion. When it abuts against the outer periphery of the first rotating shaft or the second rotating shaft, due to the bent shape, the contact area with the first rotating shaft or the second rotating shaft is increased, so that a greater frictional force can be provided to better fix the first rotating shaft or the second rotating shaft; the stretching member can move along a direction perpendicular to the axial direction of the first rotating shaft or the second rotating shaft, thereby driving the bent portion to abut against or disengage from the first rotating shaft or the second rotating shaft. By moving the position of the stretching member, the fixing and releasing of the first rotating shaft or the second rotating shaft can be achieved, and the operation is convenient.

[0039] 3. The frame structure of the bag arranging machine provided by the present invention, the locking device further includes a limiting member, which is adapted to connect the stretching member and the corresponding first mounting bracket or the second mounting bracket to limit the position of the stretching member; and the stretching member has an abutting position where the friction belt abuts against the first rotating shaft or the second rotating shaft, and a disengaging position where the friction belt is away from the first rotating shaft or the second rotating shaft.

[0040] The present invention provides a limiting member to limit the position of the stretching member. When the stretching member is in the abutting position, the limiting member can prevent the stretching member from being driven to move by the restoring force of the elastic force of the friction belt itself, the pulling force generated by the gravity of the friction belt, and the pressure of the first rotating shaft or the second rotating shaft on the friction belt, so that the friction belt disengages from or loosens the abutment with the first rotating shaft or the second rotating shaft, and further causes the first rotating shaft or the second rotating shaft to rotate. When the stretching member is in the disengaging position, the limiting member can prevent the stretching member from moving under the action of an external force or due to the vibration of the bag arranging machine, which may cause the friction belt to contact the first rotating shaft or the second rotating shaft, affecting the normal operation of the first rotating shaft or the second rotating shaft and further affecting the normal operation of the bag arranging machine.

[0041] 4. The frame structure of the bag arranging machine provided by the present invention further includes a first transmission tooth part disposed on the first mounting bracket, and the first transmission tooth part is adapted to drive the first rotating shaft to rotate; a second transmission tooth part disposed on the second mounting bracket, and the second transmission tooth part is adapted to drive the second rotating shaft to rotate; the first transmission tooth part and the second transmission tooth part have a connected state of being in transmission connection and a separated state of being separated from each other. When in the separated state, the locking device is connected to the corresponding first rotating shaft or the second rotating shaft.

[0042] The present invention is provided with a first transmission tooth part and a second transmission tooth part that are in transmission connection to drive the relative rotation of the first rotating shaft and the second rotating shaft, so as to enable the bag arranging machine to perform bag arranging operations. When the first mounting bracket and the second mounting bracket are separated, the first transmission tooth part and the second transmission tooth part are also separated. Under the fixing action of the locking device on the corresponding first rotating shaft or the second rotating shaft, the first transmission tooth part and the second transmission tooth part are also restricted by the corresponding first rotating shaft or the second rotating shaft and cannot rotate. Therefore, the state before separation can be maintained, so that when the first mounting bracket and the second mounting bracket are combined, during the subsequent combination process of the first transmission tooth part and the second transmission tooth part, since they always maintain the state before separation, they can be smoothly engaged, and there will be no situation where the first transmission tooth part and the second transmission tooth part cannot be engaged due to rotation in the separated state, resulting in the inability of the first mounting bracket and the second mounting bracket to be combined, and the first transmission tooth part and the second transmission tooth part cannot be in transmission connection, making the bag arranging machine unable to be reset.

[0043] 5. The frame structure of the bag arranging machine provided by the present invention, the first transmission tooth part includes: a runner located on the first rotating shaft, and a first intermediate wheel that is in transmission connection; the second transmission tooth part includes: a runner located on the second rotating shaft, and a second intermediate wheel that is in transmission connection; when in the connected state, the first intermediate wheel is meshed and connected with the second intermediate wheel, and when in the separated state, the first intermediate wheel and the second intermediate wheel are stationary.

[0044] The present invention provides a first intermediate wheel and a second intermediate wheel to connect the first rotating shaft and the second rotating shaft in transmission. When the first mounting frame and the second mounting frame are separated, the first intermediate wheel and the second intermediate wheel are also separated accordingly. Under the fixing action of the locking device on the corresponding first rotating shaft or the second rotating shaft, the first intermediate wheel and the second intermediate wheel are limited by the corresponding first rotating shaft or the second rotating shaft and cannot rotate, so that the state before separation can be maintained, so that when the first mounting frame and the second mounting frame are combined, the first intermediate wheel and the second intermediate wheel can mesh smoothly during the process of combining, because the first intermediate wheel and the second intermediate wheel always maintain the state before separation, and thus the two cannot mesh due to the rotation of the first intermediate wheel and the second intermediate wheel in the separated state, thereby causing the first mounting frame and the second mounting frame to be unable to be combined, and the first intermediate wheel and the second intermediate wheel cannot be connected in transmission, so that the bag sorting machine cannot be reset. At the same time, the provision of the first intermediate wheel and the second intermediate wheel makes the gear transmission structure more compact and helps to reduce the weight.

[0045] 6. The bag sorting machine frame structure provided by the present invention, the guide device includes a guide shaft, which is arranged in a direction perpendicular to the axial direction of the first rotating shaft and the second rotating shaft, and the guide shaft is fixedly connected to one of the first mounting frame and the second mounting frame, and is slidably connected to the other of the first mounting frame and the second mounting frame.

[0046] The guiding device of the present invention includes a guiding shaft, which is fixedly connected to one of the first mounting frame and the second mounting frame, and is slidably connected to the other of the first mounting frame and the second mounting frame. When the first mounting frame and the second mounting frame are driven to separate and combine, the guiding shaft moves with one of the first mounting frame and the second mounting frame, so that the other of the first mounting frame and the second mounting frame moves relative to the guiding shaft, thereby separating and combining the first mounting frame and the second mounting frame along the guiding shaft, so that the first mounting frame and the second mounting frame will not be misaligned when they are reset and combined.

[0047] 7. The bag sorting machine frame structure provided by the present invention further includes a positioning device, which is suitable for connecting the first mounting frame and the second mounting frame to define the relative position of the first mounting frame and the second mounting frame.

[0048] The present invention provides a positioning device to limit the relative position of the first mounting frame and the second mounting frame. When the first mounting frame and the second mounting frame are in a matched state, the positioning device connects the first mounting frame and the second mounting frame to prevent the two from being separated under the action of external force or vibration, which would cause the bag sorting machine to be unable to operate normally.

[0064] A first mounting frame 1, adapted to be provided with a rotatable first rotating shaft 3. A blade structure 28 is provided around the first rotating shaft 3, and a plurality of blade structures 28 are arranged along the axial direction of the first rotating shaft 3. The blade structure 28 has a plurality of claws 26, and the accommodating space 27 between two adjacent claws 26 is used to accommodate the falling packaging bags.

In this embodiment, the second mounting frame 2 forms a space adapted to accommodate a plurality of blade structures 28 on the second rotating shaft 4.

[0066] When the packaging bag falls, the packaging bag is accommodated in the accommodating space 27 between two adjacent claws 26. While the blade structure 28 rotates, the packaging bag is changed from the original vertical state to the horizontal state. After the blade structure 28 continues to rotate, the packaging bag is placed in the stacking space below the first mounting frame 1 and the second mounting frame 2.

[0067] The guiding device 8 connects the first mounting bracket 1 and the second mounting bracket 2. The structure of the guiding device 8 is not specifically limited in this embodiment. Preferably, the guiding device 8 in this embodiment includes a guiding shaft 5, a linear bearing mounting portion 6 and a guiding shaft mounting portion 7.

The linear bearing mounting portion 6 is arranged on the first mounting bracket 1, and the linear bearing mounting portion 6 is provided with a linear bearing slidably connected to the guiding shaft 5, so that the guiding shaft 5 is fixedly connected to the second mounting bracket 2 and slidably connected to the first mounting bracket 1, thereby enabling the first mounting bracket 1 and the second mounting bracket 2 to separate or combine along the guiding shaft 5. Of course, in other embodiments, the guiding shaft 5 can also be slidably connected to the second mounting bracket 2 and fixedly connected to the first mounting bracket 1. Of course, in other embodiments, the linear bearing mounting portion 6 and the guiding shaft mounting portion 7 can also be not provided, and the guiding shaft 5 can be directly fixedly connected to one of the first mounting bracket 1 and the second mounting bracket 2, and a sliding hole perpendicular to the axial directions of the first rotating shaft 3 and the second rotating shaft 4 is provided in the other, and the guiding shaft 5 is adapted to extend into the sliding hole and slide along the length direction of the sliding hole.

Of course, in other embodiments, the handle 22 can also be provided on the first mounting bracket 1, and by manually pushing or pulling, the first mounting bracket 1 is driven to move along the guiding device 8 towards or away from the second mounting bracket 2. Of course, in other embodiments, a telescopic cylinder can also be provided to drive the first mounting bracket 1 and the second mounting bracket 2 to separate or combine.

[0069] The locking device 12, corresponding locking devices 12 are provided on both the first mounting bracket 1 and the second mounting bracket 2. The locking device 12 includes a friction belt 9, which is adapted to abut against the first rotating shaft 3 or the second rotating shaft 4 to provide a frictional force for preventing the first rotating shaft 3 or the second rotating shaft 4 from rotating; a driving portion 10, which drives the friction belt 9 to move towards or away from the first rotating shaft 3, or, towards or away from the second rotating shaft 4.

[0070] In this embodiment, the structures of the friction belt 9 and the driving part 10 are not specifically limited. Preferably, the locking device 12 of this embodiment further includes a mounting base 23, which is used to mount the friction belt 9 and the driving part 10 and is connected to the corresponding first mounting bracket 1 or second mounting bracket 2 to arrange the friction belt 9 and the driving part 10 on the corresponding first mounting bracket 1 or second mounting bracket 2. The friction belt 9 of this embodiment is preferably a belt, which is bent to form a bent portion, and the bent portion is adapted to abut against the outer periphery of the first rotating shaft 3 or the second rotating shaft 4. The friction belt 9 has a fixed end and a movable end. The fixed end is connected to the mounting base 23 through a bent second locking piece 25, thereby connecting the friction belt 9 to the corresponding first mounting bracket 1 or second mounting bracket 2, and the movable end is connected to the driving part 10 through a straight first locking piece 24. The driving part 10 in this embodiment includes a stretching member and a limiting member 11. The stretching member is movably connected to the first mounting bracket 1 or the second mounting bracket 2 along a direction perpendicular to the axial direction of the first rotating shaft 3 or the second rotating shaft 4. Preferably, by providing a through hole suitable for the movement of the stretching member on the mounting base 23, the stretching member is movably connected to the first mounting bracket 1 or the second mounting bracket 2. The end of the stretching member away from the first rotating shaft 3 or the second rotating shaft 4 is a hand-held end, so as to drive the stretching member to move by hand-pushing and pulling. The end of the stretching member facing the first rotating shaft 3 or the second rotating shaft 4 is provided with a first locking piece 24 and is connected to the friction belt 9 through the first locking piece 24, so as to drive the bent portion to move towards or away from the first rotating shaft 3, or towards or away from the second rotating shaft 4 by driving the stretching member to move. The limiting member 11 is adapted to connect the stretching member and the corresponding first mounting bracket 1 or second mounting bracket 2 to limit the position of the stretching member. And the stretching member has an abutting position where the friction belt 9 abuts against the first rotating shaft 3 or the second rotating shaft 4, and a disengaging position where the friction belt 9 is away from the first rotating shaft 3 or the second rotating shaft 4.In this embodiment, the limit member 11 is preferably a nut threadedly connected to the stretching member, and the outer peripheral wall of the stretching member is provided with a thread suitable for connecting the limit member 11, so that the limit member 11 can move along the axial direction of the stretching member. In this embodiment, there are at least two limit members 11, one of which is arranged on the side of the mounting seat 23 away from the first rotating shaft 3 or the second rotating shaft 4, and is used to limit the abutment position, that is, when the friction belt 9 abuts the first rotating shaft 3 or the second rotating shaft 4, the position of the stretching member is limited by abutting the mounting seat 23 to prevent the stretching member from moving toward the first rotating shaft 3 or the second rotating shaft 4, so that the friction belt 9 is out of contact with the first rotating shaft 3 or the second rotating shaft 4, resulting in the inability to lock the first rotating shaft 3 or the second rotating shaft 4. The other of the limit members 11 is arranged on the side of the mounting seat 23 facing the first rotating axis 3 or the second rotating axis 4, and is used to limit the limit position of the disengagement position, that is, the limit position of the stretching member away from the first rotating axis 3 or the second rotating axis 4, that is, to limit the limit stretching state of the friction belt 9, to avoid excessive displacement of the stretching member and excessive force on the friction belt 9, resulting in the friction belt 9 breaking. Of course, since the limit member 11 adopts a nut that can move along the axial direction of the stretching member, it also has the following functions. First, double nut locking can be achieved through the positions of the two limit members 11 to produce an anti-loosening effect, to avoid loosening when only one limit member 11 is used, resulting in movement of the stretching member. Secondly, the limit member 11 The movement of the member 11 makes it possible to adjust the limit position of the stretching member away from the first rotating shaft 3 or the second rotating shaft 4. When the friction belt 9 is stretched and used multiple times and causes its own length to increase, the limit position can be adjusted so that the friction belt 9 can still maintain the contact with the first rotating shaft 3 or the second rotating shaft 4 without causing a decrease in the friction effect; of course, in other embodiments, the limit member 11 can also adopt a latch structure, and the stretching member is provided with a plurality of sockets arranged along its axial direction, and the latch is suitable for being plugged into the sockets and abutting against the first mounting frame 1 or the second mounting frame 2 to limit the position of the stretching member; of course, in other embodiments, the driving unit 10 may also not be provided with the limit member 11, but only be provided with a stretching member.
