Description

Technical Field

[0001] The utility model relates to the field of packaging equipment, in particular to a quick replacement device for a synchronous belt of a multi-row horizontal sealing machine. Background Art

[0002] In the traditional transverse sealing mechanism, the rotating shaft of the synchronous belt is connected to the swing arm structure. The rotating shaft is a complete connecting shaft. Therefore, if you want to replace the synchronous belt, you cannot remove the entire shaft from the swing arm structure. You can only remove the swing arm structure. The removed synchronous belt will be connected with the swing arm structures on both sides. In this process, disassembling and reinstalling the swing arm structure is time-consuming and labor-intensive, making the entire maintenance process very inefficient.

[0003] To solve the above problems, we made a series of improvements. Utility Model Content

[0004] The purpose of the utility model is to provide a quick replacement device for the synchronous belt of a multi-row horizontal sealing machine to overcome the above-mentioned shortcomings and deficiencies existing in the prior art.

[0005] A device for quickly replacing the synchronous belt of a multi-row horizontal sealing machine comprises: a coupling, a transmission shaft, a swing arm shaft and a photoelectric sensor sheet, wherein both ends of the transmission shaft are connected to the swing arm shaft through a coupling, the swing arm shaft is connected to a swing arm mechanism, a photoelectric sensor sheet is provided on the transmission shaft, and the transmission shaft is connected to a synchronous pulley of the synchronous belt.

[0006] Furthermore, the connection between the swing arm shaft and the transmission shaft is an L-shaped cross-section.

[0007] Beneficial effects of the utility model:

[0008] Compared with the traditional technology, the utility model divides the traditional synchronous belt shaft into two swing arm shafts and a transmission shaft, and then connects them through a coupling, so as to achieve faster and more efficient replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following is a further description of the present invention in conjunction with specific embodiments. It should be understood that the following embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0018] Example 1

[0019] Figure 1 It is a structural schematic diagram of the utility model. Figure 2 It is a schematic diagram of the structure of the transmission shaft and the swing arm shaft. Figure 3 It is a schematic diagram of the structure of the coupling. Figure 4 This is a usage state diagram of the utility model. Figure 5 Schematic diagram of the structure of a traditional device.

[0020] like Figure 1-4 As shown, a device for quickly replacing the synchronous belt of a multi-row horizontal sealing machine includes: a coupling 100, a transmission shaft 200, a swing arm shaft 300 and a photoelectric sensor sheet 400. Both ends of the transmission shaft 200 are connected to the swing arm shaft 300 through the coupling 100. The swing arm shaft 300 is connected to the swing arm mechanism 1. The transmission shaft 200 is provided with a photoelectric sensor sheet 400. The transmission shaft 200 is connected to the synchronous pulley 3 of the synchronous belt 2.

[0021] The connection between the swing arm shaft 300 and the transmission shaft 200 is an L-shaped cross section.

[0022] like Figure 5 As shown, the structural changes of the utility model include the following aspects: the traditional rotating shaft is a complete shaft, and the utility model breaks it into three sections starting from the connection between its two ends and the swing arm mechanism 1. They are: two swing arm shafts 300 and a transmission shaft 200. The two swing arm shafts 300 are connected to the swing arm mechanism 1, and the photoelectric sensor sheet 400 and the synchronous pulley 3 of the synchronous belt 2 are installed on the transmission shaft 200. With this design, the transmission shaft and the synchronous belt 2 thereon are independent. At this time, the transmission shaft 200 and the swing arm shaft 300 are fixed by the coupling 100 to restore the basic synchronous belt transmission function.

[0023] like Figure 4As shown, in the implementation process, first, we design the connection part of the transmission shaft 200 and the swing arm shaft 300 into an L-shaped cross-section. Then it can be connected by an L-shaped interlocking connection, and then fixed with the coupling 100. This connection method forms a complete cylinder by cross-jointing two L-shaped cross-section axes. It not only increases the stability and strength of the connection, but also facilitates disassembly and maintenance. Secondly, the fixing method of the coupling 100 is a wrapped coupling with three screw holes and screws. Such a design is very convenient for disassembly. Finally, the photoelectric sensor sheet 400 can help the rotating shaft composed of the transmission shaft 200 and the swing arm shaft 300 find the origin to ensure its precise positioning and stability.

[0024] Therefore, in this structural design, when we want to disassemble the synchronous belt, we do not need to disassemble the swing arm mechanism 1. Instead, we can directly disassemble the coupling 100. At this time, the swing arm shaft 300 is fixed on the swing arm mechanism 1, and the transmission shaft 200 together with the synchronous belt 2 can be disassembled. The overall efficiency is greatly improved.

[0025] Compared with the traditional technology, the utility model divides the traditional synchronous belt shaft into two swing arm shafts and a transmission shaft, and then connects them through a coupling, so as to achieve faster and more efficient replacement.

[0026] The specific implementation modes of the present invention are described above, but the present invention is not limited thereto. The present invention can also have various changes without departing from the purpose of the present invention.
