Description

Technical Field

[0001] This utility model relates to the field of cigarette machine design technology, and in particular to a bearing mounting assembly and its packaging device. Background Technology

[0002] The GDX1 packaging machine uses a suction roller to pick up individual sheets of sealing paper from the sealing paper magazine. These sheets are then conveyed to the adhesive application position via the first and second guide rollers. The adhesive is applied to the sealing paper before it continues to be conveyed downwards. Since both the first and second guide rollers are bearings, wear and jamming can occur after prolonged operation, leading to defects such as misaligned seals. In severe cases, sealing paper blockage can cause the GDX1 packaging machine to stop. Therefore, regular inspection and maintenance of the bearings on the first and second guide rollers are necessary. Replacing the first guide roller is relatively easy, but replacing the second guide roller is more time-consuming and labor-intensive. During installation, the gaps between the two sides of the second guide roller and the bearing housing are very small, and two very thin shims are required. The installation pin also lacks a guiding structure. Precise alignment of the holes on the bearing housing, the two thin shims, and the bearing is required, necessitating repeated alignment multiple times. This results in a long installation time and low efficiency. Furthermore, the shims are small and easily lost after disassembly. Utility Model Content

[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] The bearing mounting assembly and packaging device provided by this utility model improve the bearing mounting efficiency and the packaging device improves the packaging efficiency.

[0036] like Figure 2 and Figure 3As shown, the bearing mounting assembly includes a mounting base 1, a first fixing member 2, and a second fixing member 3. The mounting base 1 has a receiving groove 11 for accommodating the bearing 10. The mounting base 1 has two mounting through holes 12, which are located on both sides of the receiving groove 11 and communicate with it. The two mounting through holes 12 extend along a first direction and are aligned along the first direction. The two inner walls of the receiving groove 11 are provided with annular protrusions 13, which surround the mounting through holes 12. The first fixing member 2 and the second fixing member 3 can pass through the two mounting through holes 12 respectively, and the first fixing member 2 and / or the second fixing member 3 passes through the inner hole of the bearing 10. The first fixing member 2 and the second fixing member 3 can fix the bearing 10 and the mounting base 1, and the ends of the first fixing member 2 and the second fixing member 3 that are far apart from each other can be flush with the outer surface of the mounting base 1. The first direction is as follows: Figure 2 As shown in the X direction.

[0037] The bearing mounting assembly provided by this utility model includes a mounting base 1, a first fixing member 2, and a second fixing member 3. The receiving groove 11 protects the bearing 10 installed within it, reducing impacts and preventing wear. The two inner walls of the receiving groove 11 are provided with annular protrusions 13, which abut against the inner ring of the bearing 10, ensuring that the outer ring of the bearing 10 rotates within the receiving groove 11. Simultaneously, the annular protrusions 13 are fixedly connected to the mounting base 1 to prevent loss. Since the two mounting through holes 12 are aligned, during installation, only the inner hole of the bearing 10 needs to be aligned with one of the mounting through holes 12, reducing the difficulty of bearing installation and improving installation efficiency.

[0038] This embodiment does not specifically limit the shape of the mounting base 1 and the receiving groove 11. For example, the mounting base 1 is a rectangular block, and a rectangular receiving groove 11 is provided at the bottom of the mounting base 1 to facilitate processing.

[0039] The mounting through hole 12 is used to pass through the first fixing member 2 and the second fixing member 3. Exemplarily, the mounting through hole 12 includes a cylindrical hole section 121 and a frustum-shaped hole section 122 connected to each other. The cylindrical hole section 121 extends along a first direction and is close to the inner wall of the receiving groove 11. The frustum-shaped hole section 122 is frustum-shaped, with its large end opening aligned with the outer surface of the mounting base 1, and its small end connected to the cylindrical hole section 121. The frustum surface of the frustum-shaped hole section 122 can position the first fixing member 2 or the second fixing member 3, allowing the first fixing member 2 and the second fixing member 3 to slide along the frustum surface to the cylindrical hole section 121 without the need for other positioning components, reducing installation steps and improving installation efficiency.

[0040] Specifically, the first fixing member 2 includes a first head 21, and the second fixing member 3 includes a second head 31. Both the first head 21 and the second head 31 are frustoconical, and their frustoconical surfaces can fit against the frustoconical surface of the frustoconical hole section 122. This increases the contact area, reduces local stress concentration, avoids deformation or breakage caused by local overload, and improves service life. Simultaneously, when the frustoconical surfaces of the first head 21 and the second head 31 fit against the frustoconical surface of the frustoconical hole section 122, when the first fixing member 2 and the second fixing member 3 are subjected to vibration, the normal pressure between the two frustoconical surfaces is converted into frictional force that prevents them from rotating relative to each other, reducing loosening and improving connection stability.

[0041] The first fixing member 2 can be locked to the second fixing member 3 to fix the bearing 10 and the bearing 10 seat. The first fixing member 2 can be plugged into, magnetically connected to, or threadedly connected to the second fixing member 3.

[0042] For example, the first fastener 2 includes a first connecting part 22, and the second fastener 3 includes a second connecting part 33. The first connecting part 22 and the second connecting part 33 are respectively provided through two mounting through holes 12. The first connecting part 22 can be fixedly connected to the inside of the first connecting part 22, which can save installation space.

[0043] Specifically, participate in Figure 2 and Figure 3 The first connecting part 22 is a threaded rod, and the second connecting part 33 is a sleeve with threads inside. The first connecting part 22 can be screwed onto the second connecting part 33. The threaded connection is convenient and self-locking, which improves the connection stability.

[0044] Furthermore, a guide surface 32 is provided at the end of the second fixing member 3 away from the second head 31. The guide surface 32 is a frustum. During the contact between the guide surface 32 and the frustum of the mounting through hole 122, the frustum of the mounting through hole 122 will provide guidance for the second fixing member 3, guiding the second fixing member 3 to extend into the mounting through hole 12, reducing the installation difficulty and improving the installation efficiency.

[0045] To facilitate the rotation of the first fixing member 2 and the second fixing member 3, a first rotating groove 211 is formed on the surface of the first head 21 away from the receiving groove 11, and a second rotating groove 311 is formed on the surface of the second head 31 away from the receiving groove 11. The first rotating groove 211 and the second rotating groove 311 can be adapted to existing rotating tools, such as screwdrivers, reducing installation difficulty and improving installation efficiency.

[0046] This embodiment does not specifically limit the shape of the first rotating groove 211 and the second rotating groove 311. For example, both the first rotating groove 211 and the second rotating groove 311 are internal hexagonal grooves. The hexagonal structure of the internal hexagonal groove is symmetrical, and the force is evenly distributed, which can reduce the risk of groove deformation or breakage. At the same time, the internal hexagonal grooves are formed in the first head 21 and the second head 31, and the internal hexagonal grooves are recessed inward to ensure that the first head 21 and the second head 31 are flush with the outer surface of the mounting base 1, thereby improving the installation accuracy.

[0047] It is understandable that the first head 21 and the second head 31 are flush with the outer surface of the mounting base 1, and the frustum surfaces of the first head and the second head 31 will fit against the frustum surface of the mounting base 1. This design makes the first fixing member 2, the second fixing member 3 and the mounting through hole 12 tightly connected, reducing vibration interference and improving connection strength.

[0048] Optionally, the first connecting part 22 is a cross rod, and the second connecting part 33 has a cross-shaped limiting groove extending along the first direction. The first connecting part 22 can be inserted into the limiting groove, making the connection convenient. The cooperation between the cross rod and the cross-shaped limiting groove can prevent twisting and improve the connection stability.

[0049] The annular protrusion 13 is used to abut against the inner ring of the bearing 10. In this embodiment, the thickness of the annular protrusion 13 is no more than 0.5 mm, which improves the installation accuracy of the bearing 10. Exemplarily, the thickness of the annular protrusion 13 can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm or 0.5 mm. Optionally, the thickness of the annular protrusion 13 is 0.2 mm.

[0050] The annular protrusion 13 can be integrally machined with the mounting base 1, or it can be a separate design. In this embodiment, the annular protrusion 13 and the mounting base 1 are integrally machined, reducing the subsequent connection steps between the annular protrusion 13 and the mounting base 1 and improving installation efficiency.

[0051] join Figure 1 The present invention also provides a packaging device, including a first paper guide roller assembly 100, a mounting frame 200 and the aforementioned bearing mounting assembly. The first paper guide roller assembly 100 is located above the bearing mounting assembly, and an elastic element 300 is provided between the bearing mounting assembly and the mounting frame 200.

[0052] The packaging device provided by this utility model improves the efficiency of inspecting and maintaining the first guide roller assembly 100 and the bearing mounting assembly, thereby improving packaging efficiency.

[0053] The elastic element 300 can buffer vibrations generated during the movement of the packaging device, reduce the impact on the bearing mounting assembly, and improve the service life of the support mounting assembly. The elastic element 300 can be an existing spring, which is readily available.

[0054] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
