Description

Technical Field

[0001] The utility model relates to a connection component, in particular to an improved aluminum foil negative pressure suction conveying connection component for a packaging machine, belonging to the technical field of cigarette manufacturing. Background Art

[0002] Generally speaking, the negative pressure suction conveying component of the aluminum foil packaging machine plays the role of conveying aluminum foil when the equipment is operating normally. When the aluminum foil is cut to a fixed length by the cutting knife and then adsorbed on the suction conveyor belt by negative pressure suction, the rotation of the suction conveyor belt will continue to convey the fixed-length aluminum foil downward to the position of the acceleration wheel, and then the acceleration wheel will convey the single aluminum foil to the paper receiving positioning block, waiting for continued packaging at the next workstation.

[0003] The existing negative pressure suction conveying connection components for aluminum foil will cause the following equipment failures after the equipment has been running for a long time: 1. The suction holes will be blocked due to the effect of negative pressure suction, which will cause the aluminum foil to be poorly adsorbed, resulting in skewness, blockage and other failures during the conveying process; 2. The suction belt will become loose or worn after the equipment has been running for a period of time. When the suction belt becomes loose, the suction belt assembly must be removed from the equipment to adjust the tension. If the suction belt is severely worn, it needs to be replaced. Similarly, the suction belt assembly must be removed before replacement; 3. When the suction belt guide wheel bearing fails and needs to be replaced, the suction belt assembly components must be removed.

[0004] Problems encountered when the above problems occur and the suction belt assembly needs to be disassembled:

[0005] 1. The connection between the transmission shaft of the suction belt assembly and the transmission shaft of the equipment is a split nylon connection block, that is to say, the nylon connection block is not fixed on the transmission shaft of the equipment, nor is it fixedly connected to the transmission shaft of the suction belt assembly. In this way, the nylon connection block is particularly easy to fall off during the disassembly and installation process, which brings great inconvenience to maintenance;

[0006] 2. The suction belt assembly is fixed to the equipment by three screws. The screw on the right is easier to see and has a larger space. It is also easier to operate during disassembly and installation and will not fall off. The installation position of the two screws on the left is relatively narrow and not easy to operate. You must use a long hexagon socket to carefully insert the screws into the installation holes and then tighten them. It is also easy for the screws to fall off when operating in this narrow space. If they fall into the equipment, do not look for them. Sometimes it only takes 5 minutes to install the suction belt assembly, but it takes 30 minutes to find the screws or connecting blocks after they fall off.

[0007] After searching, the Chinese utility model patent with announcement number CN203450439U currently discloses a transmission shaft connection structure of a negative pressure suction belt of aluminum foil paper in a packaging machine, including: a transmission shaft, a connection block, a polyurethane cross slider coupling and a negative pressure suction belt coupling, the right end of the transmission shaft is screwed with the connection block, the left end of the polyurethane cross slider coupling is provided with a left groove, and the right end of the connection block is inserted into the left groove to form an interference fit; the right end of the polyurethane cross slider coupling is provided with a right groove, and the protrusion at the left end of the negative pressure suction belt coupling is inserted into the right groove to form an interference fit; the left groove and the right groove are in a cross shape. The technical problem that the utility model patent currently still has is that it does not solve the problem that the connection block is easy to fall off during disassembly and installation; at the same time, the utility model does not solve the problem that the suction belt assembly is difficult to install.

[0008] Therefore, the key to solving the above technical problems is to develop an improved packaging machine aluminum foil negative pressure suction conveying connection component that is reasonably designed, stable and reliable, and easy and quick to install and disassemble.

[0092] Furthermore, the locking nut 4 comprises:

[0102] In summary, a more specific implementation method of the present invention is:

[0103] Before using the improved packaging machine aluminum foil negative pressure suction conveying connecting component of the above-mentioned design structure, the already manufactured connecting component needs to be installed as a spare.

[0104] The specific installation process is:

[0105] When installing the clamping connection block 2, the connection block 3 and the locking nut 4, the operator first installs the key 12 in the keyway 11 on the suction belt rotating shaft 1, and then the operator installs the clamping connection block 2 at the corresponding position of the suction belt rotating shaft 1. Next, the operator sequentially installs the newly designed connection block 3 so that a group of card slots 31 of the connection block 3 and the fixed card block 22 of the clamping connection block 2 are correspondingly engaged and connected together. Finally, the operator tightens the locking nut 4 so that the connection block 3 will not fall off;

[0106] When installing the suction belt assembly 8 and connecting the suction belt assembly 8 to the base 72 of the device 7, first connect the other set of slots 31 of the connecting block 3 on the suction belt assembly 8 with the connecting block of the transmission shaft connecting block 5. Then, the operator completes the installation and locking of the fastening bolts 62 at the fastening holes at the bevel of the base 81, so that the suction belt assembly 8 will not fall off. Then, use a T-shaped Allen wrench to reach into the device 7 to install the fastening bolts 62 at the non-beveled edge, so that there is no risk of the fastening bolts 62 falling off. Finally, the installation of the suction belt assembly 8 and the device 7 is completed.

[0107] During use, when the fastening bolt 62 is removed, after being completely removed and loosened, the fastening bolt 62 will not fall out of the hole due to the internal threaded hole of the fastening block 61, so there is no need to consider the risk of the fastening bolt 62 falling into the equipment;

[0108] When it is necessary to install the fastening bolt 62, we screw the fastening bolt 62 into the internal thread hole of the fastening block 61, and the front end should not exceed the base 81, because the internal thread of the nylon fastening block itself has a self-locking function.

[0109] When the utility model is installed, subsequent work can be carried out. The specific working process is the same as the original existing technical working method. The negative pressure suction conveying component of the aluminum foil of the packaging machine plays the role of conveying the aluminum foil when the equipment is operating normally. When the aluminum foil is cut to a fixed length by the cutting knife, it is adsorbed on the suction conveyor belt by negative pressure suction. The rotation of the suction conveyor belt will continue to convey the fixed-length aluminum foil downward to the position of the acceleration wheel, and then the acceleration wheel will convey the single aluminum foil to the paper receiving positioning block, waiting for continued packaging at the next workstation.

[0110] In the above-mentioned whole implementation operation process, since the utility model improves the suction belt rotating shaft of the existing packaging machine suction belt assembly, its shaft end can connect the connecting block 3 to the suction belt rotating shaft 1 through the locking nut 4, that is, during disassembly and installation, the connecting block 3 is always connected to the suction belt rotating shaft 1 of the suction belt assembly and will not fall off, as shown below Figures 3 to 5As shown; this design enables the connecting block 3 to be firmly connected to the suction belt rotating shaft 1, and can prevent the connecting block 3 from falling off when installing and disassembling the aluminum foil suction belt assembly components, thereby improving the maintenance efficiency of the aluminum foil suction belt assembly components, while reducing the installation and disassembly time, thereby reducing time costs.

[0111] The utility model improves the transmission shaft connecting block on the shaft head of the existing packaging machine transmission shaft 71, which can correspond to the connecting component of the suction belt rotating shaft head of the improved suction belt assembly, and is adapted to be connected with the connecting block 3, as follows Figure 1 and Figure 2 As shown; this design can ensure perfect compatibility with the newly designed suction belt assembly 8, thereby improving the efficiency of disassembly and installation.

[0112] The utility model reconstructs the fastening hole on the existing aluminum foil suction belt assembly base that is inconvenient to install the fastening screw into a larger square hole, and then processes a nylon fastening block 61 with a square outside and a threaded hole in the middle, and sets the fastening block 61 in the square space of the base 81; at the same time, the existing full-thread fastening screw is changed to a half-thread fastening bolt 62, as shown below Figures 3 to 5 As shown; this design can ensure that when installing and disassembling the aluminum foil suction belt assembly components, the aluminum foil suction belt assembly can be quickly installed on the equipment through the newly designed fastening bolts, thereby reducing the installation and disassembly time and thus improving the installation efficiency.

[0113] Finally, it should be noted that the above has been combined with the embodiments and drawings to clearly and completely describe the concept, specific structure and technical effects of the utility model, so as to fully understand the purpose, characteristics and effects of the utility model.

The various technical features in the creation of the utility model can be combined interactively without conflicting with each other.
