Description

Technical Field

[0001] This utility model relates to the field of tobacco machinery assembly technology, and in particular to a tooling for installing the end cap of a separate drum on a loading machine. Background Technology

[0002] Currently, the YJ27 assembly machine's separating drum uses a cylindrical end-face cam mechanism to separate tobacco strips. The separation drum's motion is as follows: the outer and inner cams are fixed, and the curve of the outer cam on the cylindrical end face rises in the same direction as the inner cam, but in opposite directions. When the drum rotates, it drives the rollers and two sets of sliders to rotate around the cam center. The inner slider is fixed to the inner cam shaft by bolts passing through threaded holes and slides only on the outer cam shaft; the outer slider is fixed to the outer cam shaft by bolts passing through threaded holes and slides only on the inner cam shaft. During the drum's rotation, a compression spring presses the cam shaft and rollers tightly against the cam surface. The rollers move along the rising curves of the outer and inner cams on the cylindrical end face, respectively. The inner and outer cam shafts move to the inner and outer sides of the drum, respectively, driving the sliders to move to both sides, thus achieving the separation of the tobacco strips.

[0003] The compression spring is supported by the separator drum end cap. When installing the separator drum end cap, the large spring force makes it difficult to press the end cap onto the separator drum. In existing technology, manual labor or long bolts are typically used to press the end cap onto the separator drum, and then bolts are used to secure it at a suitable distance. This installation is time-consuming and labor-intensive, usually requiring two people. Furthermore, the large spring force makes installation errors and injuries easy to occur.

[0004] Therefore, there is an urgent need for a tooling for separating the drum end cap of the assembly machine to solve the above problems. Utility Model Content

[0015] Furthermore, the mounting base has a second mounting hole with threads in the middle, and the end of the guide shaft connected to the mounting base has a threaded section, which is threadedly connected to the second mounting hole.

[0016] Furthermore, the other end of the guide shaft is provided with a first force-applying part, the outer contour of which is a regular hexagon.

[0017] Furthermore, the pressure cap includes a first cap and a second cap, both of which are disc-shaped and coaxially arranged. The diameter of the first cap is smaller than the inner diameter of the separation drum end cap, and the diameter of the second cap is larger than the inner diameter of the separation drum end cap.

[0040] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0041] This embodiment provides a tooling for installing a detachable drum end cap on a receiving machine. It is simple and convenient to operate, enables rapid installation of the detachable drum end cap, saves manpower, and has high installation efficiency.

[0042] In this embodiment, the assembly machine includes a connected drum shaft and a separating drum, the separating drum end cap being annular. Figures 1-2As shown, the mounting fixture for the drum end cap of the receiving machine includes a mounting base 1, a fixing component (not shown in the figure), a guide shaft 2, a pressure cap 3, and a tightening nut 4. The mounting base 1 has a first mounting hole 11, through which the fixing component can pass and fix the mounting base 1 to the drum shaft. One end of the guide shaft 2 is detachably connected to the mounting base 1, and the other end of the guide shaft 2 is threaded. The pressure cap 3 has a round hole, and the pressure cap 3 is fitted onto the guide shaft 2, and the pressure cap 3 can reciprocate along the axial direction of the guide shaft 2. The tightening nut 4 is fitted onto the other end of the guide shaft 2, located at the end of the pressure cap 3 furthest from the mounting base 1, and the tightening nut 4 can abut against the pressure cap 3. Understandably, when installing the separator drum end cover, first install the structure of the separator drum excluding the separator drum end cover and compression springs onto the drum shaft. Then, place multiple compression springs in the groove of the separator drum end cover. Install the mounting base 1 onto the drum shaft through the first mounting hole 11 and the fixing piece. Then, install the guide shaft 2 onto the mounting base 1. Pass the separator drum end cover through the guide shaft 2. The multiple compression springs correspond to multiple cam shafts respectively. Install the pressure cover 3 and the tightening nut 4. Press the separator drum end cover onto the separator drum by rotating the tightening nut 4. After the separator drum end cover is pressed into place, install the bolts used to fix the separator drum end cover. Remove the tightening nut 4, pressure cover 3 and guide shaft 2. Then loosen the fixing piece on the mounting base 1 and remove the mounting base 1. The operation is simple and convenient, enabling quick installation of the separator drum end cover, saving manpower, and has high installation efficiency.

[0043] Furthermore, compared to existing technologies, by setting up the aforementioned assembly machine separation drum end cover installation fixture, the compression spring and separation drum end cover of the YJ27 assembly machine separation drum can be installed simply and effortlessly, even by one person, reducing manpower consumption; at the same time, the fixture is simple and convenient to use, avoids personnel injury, and has a high level of safety.

[0044] Further, refer to Figure 2 and Figure 3 Two first mounting holes 11 and two fasteners are provided, with each first mounting hole 11 corresponding to one of the two fasteners, thereby improving the fixing effect on the mounting base 1. The first mounting hole 11 can be a through hole, and the fastener can be a bolt. The fastener passes through the first mounting hole 11 and connects to the drum shaft to fix the mounting base 1 to the drum shaft. In this embodiment, the two first mounting holes 11 are symmetrically arranged on the mounting base 1 and are located near the edge of the mounting base 1. The specific dimensions of the mounting base 1, the first mounting holes 11, and the fasteners can be determined according to actual usage requirements, and this embodiment does not impose specific limitations.

[0045] In this embodiment, to facilitate the installation of the mounting base 1 on the drum shaft and improve the stability of the separating drum, a flange cover 100 can be used. That is, before installing the mounting base 1, the flange cover 100 is first installed on the drum shaft, and then the mounting base 1 is installed on the flange cover 100 and connected to the drum shaft. Specifically, the flange cover 100 is provided with a fixing hole 101 that mates with the first mounting hole 11. The fixing member passes through the corresponding first mounting hole 11 and fixing hole 101 and is fixed to the drum shaft.

[0046] Furthermore, such as Figure 3 and Figure 7 As shown, multiple clearance grooves 13 are evenly spaced on the outer circumferential surface of the mounting base 1. It can be understood that by providing multiple clearance grooves 13 on the outer circumferential surface of the mounting base 1, after the separation drum end cover is installed, the bolts for fixing the flange cover 100 can be installed using these grooves to fix the position of the separation drum, further improving the stability of the separation drum. In this embodiment, two clearance grooves 13 are symmetrically provided on the outer circumferential surface of the mounting base 1, and a fixing groove 102 is provided on the flange cover 100. The clearance grooves 13 and fixing grooves 102 are correspondingly provided. Both the clearance grooves 13 and fixing grooves 102 can be radial grooves, and the size of the clearance groove 13 is larger than the size of the fixing groove 102 to facilitate the installation of bolts for fixing the flange cover 100 and the removal of the mounting base 1. The specific number and location of the clearance grooves 13 can be determined according to actual usage requirements; this embodiment does not impose specific limitations.

[0047] It should be noted that the flange cover 100 is used to improve the stability of the separation drum and the convenience of installing the mounting base 1, while also preventing the mounting base 1 from damaging the separation drum. The specific structure of the flange cover 100 is existing technology and is not the focus of this embodiment, so it will not be described in detail.

[0048] For example, such as Figures 3-4 As shown, the mounting base 1 has a threaded second mounting hole 12 in its middle. The end of the guide shaft 2 connected to the mounting base 1 has a threaded section 21, which is threaded into the second mounting hole 12. It is understood that by providing the threaded section 21 and the second mounting hole 12, a detachable connection between the guide shaft 2 and the mounting base 1 can be easily achieved. Of course, in other embodiments, other methods can also be used to achieve a detachable connection between the guide shaft 2 and the mounting base 1, such as snap-fit ​​connections or key connections, which can be determined according to actual usage requirements.

[0049] In this embodiment, as Figure 3As shown, the mounting base 1 includes a base body 14 and a protrusion 15 coaxially arranged with the base body 14. The second mounting hole 12 passes through the base body 14 and the protrusion 15. By providing the protrusion 15, it is convenient to improve the strength of the mounting base 1 itself and to facilitate the installation of the guide shaft 2.

[0050] Furthermore, such as Figure 4 As shown, the other end of the guide shaft 2 is also provided with a first force-applying part 22, the outer contour of which is a regular hexagon. It can be understood that by setting the first force-applying part 22 with a regular hexagonal outer contour, when the guide shaft 2 is manually driven to rotate to a certain extent or when the guide shaft 2 is just being removed, it is convenient to use tools such as wrenches to drive the guide shaft 2 to rotate, making the operation convenient and labor-saving.

[0051] For example, such as Figure 5 As shown, the pressure cap 3 includes a first cap 31 and a second cap 32. Both the first cap 31 and the second cap 32 are disc-shaped and coaxially arranged. The diameter of the first cap 31 is smaller than the inner diameter of the separation drum end cap, and the diameter of the second cap 32 is larger than the inner diameter of the separation drum end cap. It can be understood that the smaller diameter of the first cap 31 facilitates the installation of the separation drum end cap on the outside of the first cap 31, while the larger diameter of the second cap 32 limits and abuts against the separation drum end cap, preventing it from detaching from the second cap 32 and thus ensuring the driving stability of the separation drum end cap.

[0052] Further reference Figure 5 The second cover 32 has a first abutment portion 321 at its end away from the first cover 31, and the tightening nut 4 can abut against the first abutment portion 321. It is understood that the first abutment portion 321 facilitates the connection between the cover 3 and the tightening nut 4, and also ensures a certain distance between the second cover 32 and the tightening nut 4, facilitating the rotation of the tightening nut 4. In this embodiment, the first abutment portion 321 is coaxially arranged with the second cover 32, and the cross-section of the first abutment portion 321 is annular, perpendicular to the axial direction of the first abutment portion 321. The guide shaft 2 passes through the first cover 31, the second cover 32, and the first abutment portion 321, preventing the first abutment portion 321 from interfering with the reciprocating movement of the cover 3 along the guide shaft 2.

[0053] Furthermore, such as Figure 6As shown, the tightening nut 4 includes a second abutting part 41, a main body part 42, and a second force-applying part 43 connected in sequence. The second abutting part 41 can abut against the first abutting part 321. It can be understood that by providing the second abutting part 41, it is convenient for the tightening nut 4 to abut against the pressure cap 3, so as to drive the pressure cap 3 to move. In this embodiment, the tightening nut 4 can be formed by welding the second abutting part 41, the main body part 42, and the second force-applying part 43, or by integral molding.

[0054] Furthermore, the outer peripheral surface of the main body 42 is provided with an embossed surface. By providing an embossed surface on the outer peripheral surface of the main body 42, when the worker holds the main body 42 to drive the tightening nut 4, the embossed surface on the outer peripheral surface of the main body 42 increases the friction, thereby facilitating the driving of the tightening nut 4 and preventing slippage. The specific type of embossed surface can be determined according to actual usage requirements, and this embodiment does not impose a specific limitation.

[0055] Furthermore, such as Figure 6 As shown, the outer contour of the second force-applying part 43 is a regular hexagon. It can be understood that by setting the second force-applying part 43 with a regular hexagonal outer contour, when the tightening nut 4 is manually driven to rotate to a certain extent or when the tightening nut 4 is just being loosened, it is convenient to use tools such as wrenches to drive the tightening nut 4 to rotate, making the operation convenient and labor-saving.

[0056] In this embodiment, the process of using the disassembly machine to separate the drum end cap installation fixture is as follows:

[0057] First, install the structure of the separation drum, excluding the separation drum end cover and the compression spring, onto the drum shaft. Then, install the flange cover 100 onto the drum shaft and place the compression spring inside the separation drum end cover.

[0058] Then, the mounting base 1 is fixed to the drum shaft by passing the fastener through the first mounting hole 11 of the mounting base 1 and the fixing hole 101 of the flange cover 100.

[0059] Then, the guide shaft 2 is fixed to the first mounting hole 11 of the positioning base through the threaded section 21, and the separation drum end cap is inserted through the guide shaft 2 with the compression spring facing the mounting base 1.

[0060] Next, the pressure cap 3 and the tightening nut 4 are sequentially fitted onto the guide shaft 2, and the tightening nut 4 is rotated to press the separation drum end cap onto the separation drum until the separation drum end cap abuts against the separation drum.

[0061] After the separation drum end cover abuts against the separation drum, install the bolts of the separation drum end cover to fix the separation drum end cover in place, and then remove the tightening nut 4, the pressure cover 3 and the guide shaft 2.

[0062] Finally, install bolts for fixing the flange from the clearance groove 13 on the outer periphery of the mounting base 1. Then, loosen the fastener, remove the mounting base 1, and use bolts to pass through the fixing hole 101 and fix it to the drum shaft.

[0063] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
