Description

Technical Field

[0001] This utility model relates to the field of cigarette packaging machine equipment maintenance and assembly technology, and in particular to a quick disassembly and assembly tooling for a miniature bearing of an FX packaging machine. Background Technology

[0002] The FOCKE-FX high-speed hard-pack packaging machine is one of the main models in cigarette production, and its FPI cigarette pack appearance inspection assembly plays a crucial role in ensuring cigarette pack quality. The pulley assembly is a vital transmission component of the FPI cigarette pack appearance inspection assembly, working in conjunction with the toothed belt to complete the transmission process. There are more than 20 pulley assemblies, and the 619 / 8-2RS miniature bearings used inside are relatively small. When replacing or repairing these pulley bearings, conventional tools such as pulley machines and pulley clamps cannot reach inside the pulley assembly due to size limitations.

[0003] The current production line uses a conventional method of disassembling pulleys by repeatedly striking them with a thin copper rod. This method has many drawbacks. Firstly, the lack of a device to secure the pulley assembly makes it difficult to precisely control the force and direction of the striking process, easily damaging the pulley body, bearings, and surrounding components. This compromises assembly quality and may leave hidden problems even after repair, affecting the overall performance and operational stability of the equipment. Secondly, this method is extremely inefficient; replacing more than 20 sets of pulley assembly bearings takes approximately two hours, severely disrupting production, increasing equipment downtime, and ultimately leading to economic losses.

[0004] Therefore, developing a tooling system that can efficiently, accurately, and cost-effectively enable the rapid assembly and disassembly of miniature bearings in FX packaging machines to meet the urgent need for rapid equipment maintenance and ensuring production continuity is of great practical significance. Utility Model Content

[0005] In response to the work requirements and existing problems in the aforementioned background technology, the inventor has considered and innovated in order to provide a quick disassembly and assembly tooling for miniature bearings in FX packaging machines.

[0006] To solve the above problems and achieve the above objectives, the present invention adopts the following technical solution:

[0007] A quick-release tooling for miniature bearings in an FX packaging machine is used to disassemble and assemble the first miniature pulley bearing (41) and the second miniature pulley bearing (46) of the pulley assembly (4). It includes:

[0008] An expansion screw (1) has an external thread at one end;

[0009] The expansion positioning component (2) has an internal thread that matches the external thread of the expansion screw (1) and is detachably connected to the expansion screw (1);

[0010] The pulley assembly holder (3) is a hollow cylindrical structure. One end of the pulley assembly holder (3) has a slot (31) that matches the shape of the pulley assembly (4), and the bottom has an annular support seat.

[0011] As a preferred embodiment of this utility model, the expansion screw (1) includes:

[0012] The striking head (11) is a cubic structure and is connected to the connecting rod (12);

[0013] The connecting rod (12) is a cylindrical structure, with one end connected to the striking head (11) and the other end connected to the tightening head (13);

[0014] The expansion head (13) is a frustum structure, with one end connected to the connecting rod (12) and the other end connected to the threaded rod (14);

[0015] The threaded rod (14) is a cylindrical structure with external threads.

[0016] As a preferred embodiment of the present invention, the expansion positioning component (2) is composed of three hollow cylindrical sections connected together, with a threaded inner ring and two symmetrical slots (22) at the bottom. The expansion positioning component (2) is divided into three equal expansion segments (21) by three vertical slots. The length of the vertical slots is shorter than that of the expansion positioning component (2) and does not penetrate the expansion positioning component (2).

[0017] The working principle of this utility model is as follows:

[0018] 1. Installation and composition of pulley assembly

[0019] The pulley assembly (4) is mounted on the FPI cigarette pack appearance inspection assembly (9) by means of the first bolt (5), spacer (6), gasket (7) and second bolt (8). The pulley assembly (4) includes a first miniature pulley bearing (41), a first snap ring (42), a pulley bearing spacer (43), a pulley body (44), a second snap ring (45), and a second miniature pulley bearing (46).

[0020] 2. Tooling composition and assembly:

[0021] The tooling mainly includes a tensioning screw (1), an expansion positioning component (2), and a pulley assembly holder (3).

[0022] The expansion screw (1) has an external thread, one end of which is easily connected to the expansion positioning member (2) by a striking head (11) for applying external force, and the other end is detachably connected to the expansion positioning member (2) by a thread.

[0023] The expansion positioning component (2) has an internal thread that matches the external thread of the expansion screw (1). The whole is composed of three hollow cylinders connected together and divided into three equal parts by three vertical grooves (21), which facilitates radial expansion when subjected to force.

[0024] The pulley assembly holder (3) is a hollow cylindrical structure with a slot (31) at one end that matches the shape of the pulley assembly (4) for precise positioning and support of the pulley assembly (4).

[0025] 3. Assembly / disassembly principle:

[0026] Bearing disassembly operation (see) Figure 4 — Figure 10 ):

[0027] First, place the pulley assembly (4) to be disassembled onto the expansion positioning component (2), with the expansion flap (21) snapping into the first miniature pulley bearing (41) or the second miniature pulley bearing (46); then align the pulley assembly (4) and the expansion positioning component (2) with the slot (31) of the pulley assembly holder (3), ensuring that the pulley assembly holder (3) stably supports the pulley assembly (4) and the expansion positioning component (2); then insert the tightening head (13) of the tightening screw (1) into the expansion positioning component (2) and rotate the tightening screw (1). 1) Screw the threaded rod (14) into the internal thread of the expansion positioning part (2). At this time, the expansion flap (21) expands outward under the action of the tightening head (13), and tightly attaches to the first miniature pulley bearing (41) or the second miniature pulley bearing (46) of the pulley assembly (4) and applies disassembly force to make the bearing overcome the matching force between the bearing and the pulley assembly (4); then use a hammer to strike the striking head (11) of the tightening screw to easily remove the first miniature pulley bearing (41) or the second miniature pulley bearing (46) from the pulley body (44).

[0028] Bearing installation operation (see) Figure 11 — Figure 13 ):

[0029] When installing the bearing, simply use the expansion positioning component (2) and the pulley assembly holder (3) of this tooling. Insert the bearing to be replaced into the expansion positioning component (2), and then place the expansion positioning component (2) and the pulley body (44) to be installed into the slot (31) of the pulley assembly holder (3), with the expansion positioning component (2) facing outward. Then, use a hammer to tap the tail of the expansion positioning component (2) until the first miniature pulley bearing (41) or the second miniature pulley bearing (46) is inserted into the pulley body (44). Similarly, complete the installation of the first miniature pulley bearing (41) and the second miniature pulley bearing (46). During the installation process, the expansion positioning component (2) provides a stable guide for the installation of the bearing, ensuring installation efficiency and accuracy.

[0030] The beneficial effects of this utility model are:

[0031] 1. This utility model improves disassembly and assembly efficiency. By cooperating with the expansion screw and the expansion positioning component, this utility model enables rapid disassembly and assembly of miniature bearings. Compared to the traditional method of hammering with a thin copper rod, this tooling significantly shortens disassembly and assembly time and improves production efficiency.

[0032] 2. This utility model ensures precise disassembly and assembly. The pulley assembly holder of this utility model is designed with a groove that matches the shape of the pulley assembly, ensuring precise positioning of the pulley assembly during disassembly and assembly. Simultaneously, the tightening mechanism of the tightening screw and the expansion positioning component applies disassembly force evenly, avoiding the difficulty in controlling the force and direction in traditional hammering methods. This effectively reduces the risk of damage to the pulley body, bearings, and surrounding components, ensuring the overall performance and operational stability of the equipment.

[0033] 3. This utility model reduces maintenance costs. It has a simple structure, is easy to manufacture and maintain, and is reusable. By reducing damage and repair frequency during disassembly and assembly, it lowers equipment maintenance costs. Simultaneously, the increased disassembly and assembly efficiency also reduces indirect economic losses caused by downtime for maintenance. Attached Figure Description

In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concept of this utility model patent.

[0053] Example 1

[0054] like Figure 1 — Figure 16 The illustrated FX packaging machine miniature bearing quick-release tooling includes a pulley assembly 4. The pulley assembly 4 is mounted on the FPI cigarette pack appearance inspection assembly 9 via a first bolt 5, a spacer 6, a washer 7, and a second bolt 8. The pulley assembly 4 includes a first miniature pulley bearing 41, a first retaining ring 42, a pulley bearing spacer 43, a pulley body 44, a second retaining ring 45, and a second miniature pulley bearing 46. Its distinguishing feature is that it further includes:

[0057] The pulley assembly holder 3 is a hollow cylindrical structure. One end of the pulley assembly holder 3 has a groove 31 that matches the shape of the pulley assembly 4, and the bottom has an annular support seat.

[0058] Furthermore, such as Figure 15 As shown, the tightening screw 1 includes:

[0059] The striking head 11 is a cubic structure and is connected to the connecting rod 12;

[0060] The connecting rod 12 is a cylindrical structure, with one end connected to the striking head 11 and the other end connected to the tightening head 13;

[0064] In summary, the specific usage process of this utility model is as follows:

[0065] All the necessary components for this invention are prefabricated in the factory.

[0066] When disassembling the bearing, such as Figure 4 , Figure 5 As shown, firstly, the pulley assembly 4 to be disassembled is placed on the expansion positioning component 2, and the expansion flap 21 is inserted into the first miniature pulley bearing 41 or the second miniature pulley bearing 46; then, the pulley assembly 4 to be disassembled and the expansion positioning component 2 are aligned with the slot 31 of the pulley assembly holder 3 and inserted to ensure that the pulley assembly holder 3 stably supports the pulley assembly 4 and the expansion positioning component 2; then, the expansion head 13 of the expansion screw 1 is inserted into the expansion positioning component 2, and the expansion screw 1 is rotated to make the threaded rod 14 engage with the internal thread of the expansion positioning component 2. At this time, the expansion flap 21 expands outward under the action of the expansion head 13, tightly attaching and fixing the first miniature pulley bearing 41 or the second miniature pulley bearing 46 of the pulley assembly 4 and applying disassembly force to make the bearing overcome the cooperation force between the bearing and the pulley assembly 4.

[0067] Furthermore, such as Figure 6 — Figure 9 As shown, by striking the tapping head 11 of the tightening screw with a hammer, the first miniature pulley bearing 41 or the second miniature pulley bearing 46 can be easily removed from the pulley body 44, and then the pulley bearing spacer 43 between the bearings can be removed.

[0068] Furthermore, such as Figure 10 As shown, flip the remaining pulley assembly 4 and use the expansion positioning piece 2 to snap into the remaining bearing, then place it into the pulley assembly holder 3. Repeat the above disassembly operation to remove the first miniature pulley bearing 41 and the second miniature pulley bearing 46; then use snap ring pliers to remove the first snap ring 42 and the second snap ring 45.

[0069] Similarly, disassemble the pulley assembly 4 of all FPI cigarette pack appearance inspection assemblies 9, and then perform maintenance, replacement and upkeep.

[0070] Furthermore, when installing the bearing, first install the first snap ring 42 and the second snap ring 45 into the pulley body 44 using snap ring pliers, and then... Figure 11 , Figure 12 , Figure 13 As shown, simply use the expansion positioning component 2 and the pulley assembly holder 3 of this tooling to insert the bearing to be replaced into the expansion positioning component 2. Then, place the expansion positioning component 2 and the pulley body 44 to be installed into the slot 31 of the pulley assembly holder 3, with the expansion positioning component 2 facing outward. Then, use a hammer to tap the tail of the expansion positioning component 2 until the first miniature pulley bearing 41 or the second miniature pulley bearing 46 is inserted into the pulley body 44. Then, place the pulley bearing spacer 43 onto the first miniature pulley bearing 41 or the second miniature pulley bearing 46. Similarly, complete the installation of the remaining bearing.

[0071] Furthermore, using a special tool, the inner pulley bearing spacer 43 of the pulley assembly 4 is moved to the middle position. Then, the first bolt 5, spacer 6, washer 7, and second bolt 8 are used to install all pulley assemblies 4 into their original positions on the FPI cigarette pack appearance inspection assembly 9, thus completing the maintenance and upkeep of the FPI cigarette pack appearance inspection assembly 9.

[0072] Finally, it should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
