A bag arranging machine rack structure

Abstract

A bag-sorting machine frame structure, belonging to the field of packaging equipment technology, includes at least two mounting brackets suitable for mounting rotating shafts and transmission gears; a hinge shaft, through which adjacent mounting brackets are connected by a driven rotational opening and closing mechanism. The end face of the transmission gear furthest from the mounting bracket is the base end face. The longitudinal axis of the hinge shaft is located between the base end face and the mounting bracket, and the distance between the longitudinal axis and the base end face is 0 mm to m mm, ensuring that the transmission gears of adjacent mounting brackets are always meshed. This invention allows adjacent mounting brackets and rotating shafts to be connected by a driven rotational opening and closing mechanism via the hinge shaft, thereby increasing the distance between adjacent rotating shafts to create operating space without removing the rotating shafts. Simultaneously, the distance between the longitudinal axis of the hinge shaft and the base end face of the transmission gear is 0 mm to m mm, ensuring smooth rotation and closing of adjacent mounting brackets and smooth reset of the two transmission gears.

Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, and more specifically to a bag sorting machine frame structure. Background Technology

[0002] A bag sorting machine, also known as a packaging sorting device, is a type of existing bag sorting machine used to change the position of packaging bags falling vertically to horizontal for stacking. It typically consists of a symmetrically rotating shaft on the frame, and a blade structure located on and rotating around this shaft. The shaft is perpendicular to the direction of the bags' descent. The blade structure has multiple grippers, and the space between adjacent grippers accommodates the falling bags. As the bags fall, they are contained within this space. Simultaneously, the rotating blade structure changes the bags from a vertical to a horizontal position. Further rotation places the bags 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 along the radial direction of the rotating shafts is very small, almost in contact. This makes the space between the two rotating shafts very narrow. When the packaging bag gets stuck or misaligned in the space between the two grippers, or when the bag sorting machine needs maintenance or parts need to be repaired or replaced, the bag sorting machine can only be disassembled. At least one rotating shaft and its blade structure need to be removed to give the bag sorting machine the operating space to adjust and remove the packaging bag, perform maintenance, and repair or replace parts. However, the above method requires disassembling the bag sorting machine, which makes the operation cumbersome and difficult. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the existing bag sorting machine, which has a fixed position of the rotating shaft and a very narrow space between the two rotating shafts, which makes it necessary to disassemble the bag sorting machine when maintenance and repair are required, resulting in complicated and difficult operation. The present invention provides a bag sorting machine frame structure.

[0004] This invention provides the following technical solution:

[0005] A bag sorting machine frame structure, comprising:

[0006] At least two mounting brackets are provided, the mounting brackets are adapted to house a rotatable rotating shaft and a transmission gear that rotates synchronously with the rotating shaft, and the rotating shaft is provided with a blade structure;

[0007] The hinge mechanism includes a hinge shaft, through which adjacent mounting brackets are rotatably connected. The end face of the transmission gear away from the mounting bracket is the base end face. The longitudinal axis of the hinge shaft is located between the base end face and the mounting bracket, and the distance between the longitudinal axis and the base end face is 0 mm to m mm, where m is the module of the transmission gear, so that the transmission gears of adjacent mounting brackets are always meshed.

[0008] Optionally, the rotating shaft is provided with a gear section, which is connected to the transmission gear, and the tooth width of the transmission gear is not less than the tooth width of the gear section.

[0009] Optionally, the hinge mechanism further includes two connecting frames connected by a hinge shaft, the connecting frames being connected to the corresponding mounting frames, and the connecting frames having a receiving space suitable for accommodating the transmission gear, the receiving space being located in the axial direction of the hinge shaft.

[0010] Optionally, it also includes:

[0011] A drive wheel is connected to any of the gears on an adjacent mounting bracket to drive the rotating shafts on the adjacent mounting brackets to rotate relative to each other.

[0012] Optionally, it also includes:

[0013] A locking mechanism is adapted to connect adjacent mounting brackets and is located on the side of the mounting bracket opposite to the side connected to the hinge mechanism, so as to fix the position of the adjacent mounting brackets when they are engaged.

[0014] Optionally, the locking mechanism includes:

[0015] A locking buckle is provided for connecting adjacent mounting brackets.

[0016] The technical solution of this invention has the following advantages:

[0017] 1. The bag-making machine frame structure provided by the present invention includes mounting frames, at least two in number, wherein each mounting frame is adapted to have a rotatable rotating shaft and a transmission gear that rotates synchronously with the rotating shaft, and the rotating shaft is provided with a blade structure; a hinge mechanism includes a hinge shaft, wherein adjacent mounting frames are connected by being driven to rotate and open and close through the hinge shaft, the end face of the transmission gear away from the mounting frame is the base end face, the longitudinal axis of the hinge shaft is located between the base end face and the mounting frame, and the distance between the longitudinal axis and the base end face is 0 mm to m mm, where m is the module of the transmission gear, so that the transmission gears of adjacent mounting frames are always meshed and connected.

[0018] This invention features a hinge mechanism connecting adjacent mounting frames, each with a corresponding rotating shaft. This allows the adjacent mounting frames and their rotating shafts to be driven to open and close via the hinge. When a packaging bag becomes stuck or misaligned within the space between the two grippers, or when maintenance or replacement of parts is required, the adjacent mounting frames can be opened by rotating them, moving the adjacent rotating shafts away. This increases the distance between the rotating shafts, creating more operating space without requiring disassembly. This reduces the difficulty of maintenance and repairs, improving work efficiency. Furthermore, the longitudinal axis of the hinge is located between the base face of the transmission gear and the mounting frame, with a distance of 0 mm to m mm between them, where m is the module of the transmission gear. This allows the adjacent mounting frames to... The transmission gears on the mounting bracket can also rotate around the hinge axis as the mounting bracket rotates and opens. This prevents interference between the two transmission gears, which could prevent them from rotating and thus hinder the opening of adjacent mounting brackets. Furthermore, the two transmission gears maintain partial tooth engagement during rotation, remaining in the same position as before the mounting bracket rotates and opens. During the rotation and opening process, only one transmission gear rotates, preventing misalignment and ensuring that adjacent mounting brackets cannot close properly when they rotate and close. Therefore, the distance between the longitudinal axis and the base end face of the transmission gear is 0 mm to m mm, ensuring smooth rotation and closing of adjacent mounting brackets and smooth reset of the two transmission gears without manual adjustment. This improves the convenience of opening and closing adjacent mounting brackets and increases operational efficiency.

[0019] 2. The bag sorting machine frame structure provided by the present invention includes a gear section on the rotating shaft, the gear section being connected to the transmission gear, and the tooth width of the transmission gear being not less than the tooth width of the gear section.

[0020] The rotating shaft of this invention is provided with a gear section, and the tooth width of the transmission gear is not less than the tooth width of the gear section, thereby ensuring that the transmission gear can be installed on the corresponding mounting bracket. This avoids the tooth width of the gear section being too large, which would interfere with the mounting structure used to install the transmission gear, causing the transmission gear to be unable to be installed smoothly or to wobble after installation. Consequently, the meshing transmission gears may be damaged by impact or friction during rotation due to the wobble.

[0021] 3. The bag sorting machine frame structure provided by the present invention further includes two connecting frames connected by a hinge shaft. The connecting frames are connected to the corresponding mounting frames, and the connecting frames have a receiving space suitable for accommodating the transmission gear. The receiving space is located in the axial direction of the hinge shaft.

[0022] The hinge mechanism of the present invention further includes two connecting frames connected by a hinge shaft. The connecting frames have a receiving space suitable for accommodating the transmission gear. The transmission gear is arranged in the receiving space so that the hinge shaft and the transmission gear can satisfy the positional relationship that the longitudinal axis of the hinge shaft is located between the base end face of the transmission gear and the mounting frame, and the distance between the longitudinal axis and the base end face is 0 mm to m mm. This ensures that the corresponding transmission gear can always be meshed when the adjacent mounting frames rotate. At the same time, it also makes the structure of the hinge mechanism and the transmission gear more compact, reduces the space occupied by the equipment, and is beneficial to the installation of the present invention.

[0023] 4. The bag sorting machine frame structure provided by the present invention further includes a locking mechanism, which is adapted to connect adjacent mounting frames and is located on the side of the mounting frame opposite to the side connected to the hinge mechanism, so as to fix the position of the adjacent mounting frames when they are engaged.

[0024] The present invention includes a locking mechanism to fix the position of adjacent mounting frames when they are engaged, preventing them from rotating and opening under external force or due to vibrations generated by the bag sorting machine, thus ensuring the normal operation of the bag sorting machine equipped with the present invention.

[0035] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] Example 1

[0037] This embodiment provides a bag sorting machine frame structure, such as Figures 1-5 As shown, including

[0038] Mounting bracket 1 is provided at least two. In this embodiment, there are two mounting brackets 1. Of course, there can be more than two in other embodiments. The mounting bracket 1 is adapted to be provided with a rotatable rotating shaft 2 and a transmission gear 3 that rotates synchronously with the rotating shaft 2. The rotating shaft 2 is provided with a plurality of blade structures 10, and the plurality of blade structures 10 are arranged along the axial direction of the rotating shaft 2. The blade structure 10 has a plurality of claws 11. The accommodating space 12 between two adjacent claws 11 is used to accommodate the falling packaging bag. In this embodiment, the mounting bracket 1 is provided with a space suitable for accommodating a plurality of blade structures 10 on the rotating shaft 2.

[0039] This embodiment does not limit the specific structure of the transmission gear 3. Preferably, the transmission gear 3 in this embodiment is an intermediate wheel, which is mounted on the mounting shaft located on the mounting bracket 1. The rotating shaft 2 is provided with a gear part 5, which meshes and drives the transmission gear 3. That is, two adjacent rotating shafts 2 are connected by two transmission gears 3, and the two rotating shafts 2 rotate relative to each other. The tooth width of the transmission gear 3 is not less than the tooth width of the gear part 5. Of course, in other embodiments, the transmission gear 3 can also be a gear part 5, that is, the gear parts 5 of two adjacent rotating shafts 2 are directly meshed and connected.

[0040] This embodiment does not specifically limit the structure for driving the rotating shaft 2 to rotate. Preferably, in this embodiment, either of the two adjacent mounting brackets 1 is provided with a drive wheel. The drive wheel is a gear rotatably mounted on the corresponding mounting bracket 1 and meshes with the gear part 5 on the mounting bracket 1. The drive wheel is driven by the motor and drives the meshing gear part 5 to rotate, which in turn drives the other gear part 5 to rotate through the transmission gear 3, and causes the rotating shaft 2 on the adjacent mounting brackets 1 to rotate relative to each other. Of course, in other embodiments, a drive wheel may not be provided, and a rotating motor may be provided to directly drive the rotating shaft 2 to rotate.

[0041] The hinge mechanism 4 includes a hinge shaft 6, and adjacent mounting brackets 1 are connected by the hinge shaft 6 through which they are driven to rotate and open / close. Figure 5 As shown, the end face of the transmission gear 3 away from the mounting bracket 1 is the base end face. The longitudinal axis of the hinge shaft 6 is located between the base end face and the mounting bracket 1, and the distance L between the longitudinal axis and the base end face is 0 mm to [m(z+2)-mz] / 2 mm, that is, 0 mm to m mm, where m is the module of the transmission gear 3 and z is the number of teeth of the transmission gear 3, so that the transmission gears 3 of adjacent mounting brackets 1 are always meshed and connected.

[0042] This embodiment does not limit the specific structure of the hinge mechanism 4. Preferably, the hinge mechanism 4 in this embodiment further includes two connecting frames 7 connected by a hinge shaft 6. The connecting frame 7 is connected to the corresponding mounting frame 1, and the connecting frame 7 has a receiving space suitable for accommodating the transmission gear 3. The receiving space is located in the axial direction of the hinge shaft 6. In this embodiment, the mounting shaft is located in the receiving space, and one end of the mounting shaft abuts against the mounting frame 1, and the other end abuts against the connecting frame 7. The connecting frames 7, the mounting shaft, and the mounting frame 1 are connected sequentially by bolts for fixation. The transmission gear 3 is disposed on the mounting shaft. This is to ensure that the transmission gear 3 is located within the accommodating space, thereby ensuring that the longitudinal axis of the hinge shaft 6 is located between the base end face and the mounting bracket 1, and the distance L between the longitudinal axis and the base end face is 0 mm to m mm, where m is the module of the transmission gear 3; of course, in other embodiments, the connecting bracket 7 may not be provided, and adjacent mounting brackets 1 may be directly hinged through the hinge shaft 6. The hinge shaft 6 is set on one mounting bracket 1, and the other mounting bracket 1 is provided with a hole suitable for fitting the hinge shaft 6, so that the hinge shaft 6 can rotate in the hole. In this case, the mounting bracket 1 needs to have a groove to accommodate the transmission gear 3.

[0043] A locking mechanism 8 is adapted to connect adjacent mounting brackets 1 and is located on the side of the mounting bracket 1 opposite to the side connected to the hinge mechanism 4, so as to fix the position of adjacent mounting brackets 1 when they are engaged. Preferably, in this embodiment, the locking mechanism 8 includes a locking buckle adapted to connect adjacent mounting brackets 1 and a protrusion on the mounting bracket 1 adapted to install the locking buckle. One protrusion of the mounting bracket 1 is provided with a retaining ring end of the locking buckle, and the protrusion of the other mounting bracket 1 is provided with a locking buckle end. The retaining ring end and the locking buckle end are adapted to be engaged and connected. Of course, in other embodiments, the locking buckle can also adopt a press buckle structure. Of course, in other embodiments, the locking mechanism 8 can also adopt a lock body or an adhesive structure. Of course, in other embodiments, the locking mechanism 8 may not be provided.

[0044] In this embodiment, the structure for driving adjacent mounting brackets 1 to rotate open or rotate and engage is not specifically limited. Preferably, in this embodiment, one of the mounting brackets 1 is provided with a handle 9, which drives the adjacent mounting brackets 1 to rotate open or rotate and engage by manual pushing and pulling. Of course, in other embodiments, a telescopic cylinder can also be provided to drive the adjacent mounting brackets 1 to rotate open or rotate and engage.

[0045] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
