Description

Technical Field

[0001] This utility model relates to the field of stretching machine technology, and in particular to a drive device for vacuum adsorption conveying in a stretching machine. Background Technology

[0002] A stretching machine is a piece of equipment used to stretch and form the body of a beverage can (two-piece can). There are two types of stretching machines: chain conveyor belt stretching machines and vacuum adsorption conveyor stretching machines. The chain conveyor belt stretching machine uses a continuous conveyor belt to transport the can, while the vacuum adsorption conveyor stretching machine uses a disc pallet with vacuum adsorption function to transport the can.

[0003] The conveyor belt drive of the belt stretching machine and the disc pallet drive of the vacuum adsorption conveyor have different structures and cannot be used interchangeably. That is, the drive devices of the belt stretching machine and the vacuum adsorption conveying stretching machine are incompatible. A stretching machine cannot use two conveying methods. Therefore, it cannot switch between the two conveying methods arbitrarily according to production needs, which limits its application scope. Utility Model Content

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0044] Example:

[0045] like Figure 1-5 The image shows a driving device for vacuum adsorption conveying of a stretching machine provided in this embodiment, including a disc tray 1, a driving device 2, a transmission device 3, and a stretching machine body 4;

[0046] The stretching machine body 4 has mounting holes on one side. The disc tray 1, the drive device 2, and the transmission device 3 are detachably mounted on the mounting holes on the stretching machine body 4 by bolts. The mounting holes can also be used to install chain conveyor drive devices. That is, the mounting holes required for this drive device are completely consistent with the mounting holes (size and position) required for installing chain conveyor drive devices, which has stronger compatibility.

[0047] The disc pallet 1 is located on the top of one side of the stretching machine body 4, and the drive device is located on the lower side of the disc pallet 1. The drive device 2 can drive the disc pallet 1 to rotate on the stretching machine body 4 through the transmission device 3 to transport the tank.

[0048] This utility model discloses a driving device for vacuum adsorption conveying of a stretching machine. By setting a detachable disc pallet device in conjunction with a tensioning device, a driving device, and a transmission device, it can effectively drive the disc pallet (vacuum adsorption conveying). This device can quickly switch the conveyor belt stretching machine to vacuum adsorption conveying mode according to production needs, thereby realizing the function of mechanized transport of tanks and meeting production requirements.

[0049] When the chain conveyor stretching machine needs to be switched to vacuum adsorption conveying mode, the chain drive device on the chain conveyor stretching machine is removed, and the entire drive device is installed in the original mounting hole position. This will enable the switch from chain conveying mode to vacuum adsorption conveying mode, meeting the requirements of vacuum adsorption conveying tank.

[0050] In a specific embodiment, the driving device 2 includes a drive shaft 21, a drive sprocket 22, a drive chain 23, and a drive motor;

[0051] The drive motor is fixed to the side of the stretching machine body 4, the drive shaft 21 is connected to the output end of the drive motor, and the drive sprocket 22 is mounted on the drive shaft 21;

[0052] One end of the drive chain 23 is sleeved on the outside of the drive sprocket 22, and the other end of the drive chain 23 is connected to the transmission device 3.

[0053] The drive motor provides a stable and reliable power source for the entire drive unit; the drive shaft 21 is directly connected to the output end of the drive motor (coaxially connected through a coupling), which can stably transmit the power output by the drive motor to the drive sprocket 22, thereby ensuring that the drive chain 23 drives the transmission device 3 to run smoothly and ensuring the stable working state of the vacuum adsorption conveying system (disc pallet) of the stretching machine.

[0054] In a specific embodiment, the transmission device 3 is located on the lower side of the disc pallet 1, and the transmission device 3 includes a transmission shaft 31, a first transmission gear 32, a second transmission gear 33, and a transmission chain 34.

[0055] The drive shaft 31 is fixed on the stretching machine body 4. The first drive gear 32 and the second drive gear 33 are rotatably mounted on the drive shaft 31. The end of the drive chain 23 away from the drive sprocket 22 is sleeved on the outside of the first drive gear 32.

[0056] One end of the transmission chain 34 is sleeved on the outside of the second transmission gear 33, and the other end of the transmission chain 34 is connected to the disc pallet 1. The movement of the drive chain 23 can drive the first transmission gear 32 and the second transmission gear 33 to rotate, thereby driving the transmission chain 34 to rotate and driving the disc pallet 1 to rotate.

[0057] Through the gears and chains of the transmission device 3, the high speed and low torque of the drive motor can be converted into the low speed and high torque required by the disc pallet 1, which is suitable for the conveying conditions.

[0058] After the drive motor (not shown in the figure) is started, it drives the drive shaft 21 to rotate. The rotation of the drive shaft 21 drives the sprocket 22 to rotate. The rotation of the drive sprocket 22 synchronously drives the transmission chain 34 of the transmission device 3 to move and drives the second transmission gear 33 to rotate. Since the second transmission gear 33 and the first transmission gear 32 are fixed on the transmission shaft 31, the first transmission gear 32 and the transmission shaft 31 also rotate synchronously with the second transmission gear 33. The first transmission gear 32 is connected to the transmission device 3, which can drive the transmission device 3 to rotate, and finally drive the disc pallet 1 to rotate, so as to realize the transport of the tank.

[0059] In a specific embodiment, a first mounting base 5 is detachably mounted on the body 4 of the stretching machine, and a mounting shaft is rotatably mounted on the first mounting base 5 via a bearing. A first driven gear 7 and a second driven gear 8 are fixed on the mounting shaft 6.

[0060] The end of the transmission chain 34 away from the second transmission gear 33 is sleeved on the outside of the first driven gear 7. The transmission chain 34 meshes with the second transmission gear 33. The second driven gear 8 meshes with the pallet gear 11 on the disc pallet 1. The movement of the transmission chain 34 can drive the first driven gear 7 and the second driven gear 8 to rotate. The rotation of the second driven gear 8 drives the disc pallet 1 to rotate.

[0061] The first mounting base 5 is detachably mounted on the body 4 of the stretching machine by bolts, which facilitates the assembly and disassembly of this device.

[0062] The first transmission gear 32 rotates, which drives the first driven gear 7 to rotate through the transmission chain 34. Since the second driven gear 8 is fixed on the mounting shaft 6, the rotation of the first driven gear 7 drives the first driven gear 7 to rotate through the mounting shaft 6.

[0063] The device obtains power from the drive shaft 21 (drive motor), and transmits the power to the drive chain 23 via the drive sprocket 22. The drive chain 23 drives the first transmission gear 32 and the second transmission gear 33 to rotate. The second transmission gear 33 drives the first driven gear 7 and the second driven gear 8 to rotate via the transmission chain 34. Finally, the second driven gear 8 drives the disc pallet 1 to rotate, which can transfer the tank from the feeding turntable to the subsequent stabilizing turntable, forming spindle turntable or other processing stations, realizing the function of mechanized tank transportation.

[0064] In a specific embodiment, it also includes a second mounting base 9 and a tensioning device 10 disposed on the second mounting base 9 for tensioning the drive device. The tensioning device 10 includes a tensioning arm 101, a tensioning wheel 102 and a tensioning arm limiting device.

[0065] The second mounting base 9 is detachably mounted on the body 4 of the stretching machine;

[0066] One end of the tensioning arm 101 is rotatably mounted on the second mounting base 9 (fixed by bolts; loosening the bolts allows adjustment around the connection between the tensioning arm 101 and the second mounting base 9; rotating the tensioning arm 101 to a suitable position ensures the drive chain 23 is in a suitable tension state). The other end of the tensioning arm 101 is provided with the tensioning wheel 102, which is rotatably disposed at the bottom of the tensioning arm 101. The tensioning wheel 102 meshes with the outer side of the drive chain 23. A tensioning arm limiting device is provided on one side of the tensioning arm 101 to limit the angular position of the tensioning arm 101. The tensioning device ensures the tension of the drive chain 23. The result is that the meshing effect between the drive chain 23 and the drive sprocket 22 is guaranteed, thereby ensuring that the power of the drive device can be effectively transmitted to the transmission device 3; at the same time, the adjustable tension arm 101 can adjust the tension force applied to the drive chain 23, which can avoid the problem of increased frictional resistance during transmission due to excessive tension of the drive chain 23, resulting in a significant decrease in transmission speed and increased energy consumption, and can also avoid the problem of the drive chain 23 jamming or speed fluctuation due to insufficient meshing between the drive chain 23 and the drive sprocket 22 or the occurrence of "tooth skipping", thus avoiding problems such as unsmooth conveying path, transmission process and unstable conveying path, and ensuring the transport path of the tank;

[0067] The second mounting base 9 can be detachably mounted on the body 4 of the stretching machine by bolts, which facilitates the assembly and disassembly of this device.

[0068] In a specific embodiment, the tensioning arm limiting device includes a mounting block 103 and a threaded limiting post 104. The mounting block 103 is disposed on the second mounting base 9, and the threaded limiting post 104 is disposed on the mounting block 103 and can be locked onto the mounting block 103 by a nut. The bottom of the threaded limiting post 104 abuts against the top of the tensioning arm 101.

[0069] The mounting block 103 has a vertically threaded hole, and the threaded limiting post 104 is vertically installed inside the threaded hole. In actual use, the position of the threaded limiting post 104 on the mounting block 103 can be adjusted as needed by rotating the threaded limiting post 104, that is, adjusting the height of the bottom of the threaded limiting post 104 and making the bottom of the threaded limiting post 104 abut against the upper side of the tensioning arm 101. After the position is adjusted, the threaded limiting post 104 is fixed by the nut. The threaded limiting post 104 can vertically limit the tensioning arm 101 when the device is working, and at the same time provide limiting force for the tensioning arm 101 and the tensioning wheel 102, ensuring the stability of the position of the tensioning arm 101 and the tensioning wheel 102, thereby ensuring the stability of the tension force on the drive chain 23, thus ensuring the positional stability of the drive chain 23 during movement, and ultimately improving the smoothness of the rotation of the disc pallet 1, ensuring the positional stability of the tank transmission, and thus ensuring the accuracy of subsequent tank processing.

[0070] In a specific embodiment, a fixed seat 12 is also included. The transmission shaft 31 is fixedly mounted on the stretching machine body 4 through the fixed seat 12. The fixed seat 12 is detachably mounted on the mounting holes on the stretching machine body 4 by bolts, which facilitates the disassembly and assembly of the device, improves the disassembly and assembly efficiency of the device, and thus improves the switching efficiency between devices with different transmission methods.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
