Description

Technical Field

[0001] This utility model relates to the field of primary slitting wheels, and in particular to a primary slitting wheel adjustment mechanism. Background Technology

[0002] The primary slitting roller in the cigarette splicing machine aligns double-length cigarette strips and then cuts them into equal-length cigarettes. The primary slitting roller has two floats, the distance between which is adjusted via an adjustment mechanism.

[0003] Traditional adjustment mechanisms employ a double-ended screw design, with the threads at both ends rotating in opposite directions. When the double-ended screw is driven to rotate, the nuts at both ends move relative to each other, thereby causing the two float rings to move closer or further apart, thus achieving the purpose of distance adjustment.

[0004] However, traditional adjustment mechanisms lack effective dustproof and protective designs. This allows dust and foreign objects to easily penetrate the mechanism. For example, dust entering the mating area between the screw and nut can affect transmission and cause wear. Simply adding a dust cover to the adjustment mechanism to provide overall protection is insufficient. Since the adjustment mechanism needs to connect to an external float, the dust cover requires grooves to accommodate the movement of the adjustment mechanism's output end and its connection to the float. This inevitably allows dust and foreign objects to enter through these grooves, resulting in inadequate dustproof performance. Utility Model Content

[0005] This utility model provides a primary slitting wheel adjustment mechanism to solve the technical problem of poor dustproof effect.

[0006] This utility model solves the above-mentioned technical problems through the following technical solutions: This utility model provides a primary slitting wheel adjustment mechanism, including a protective cover; it also includes: a translation mechanism, which is installed inside the protective cover, and the output of the translation mechanism is connected to two connecting plates, each of which is fixedly connected to a float ring; the two float rings are respectively sleeved at both ends of the primary slitting wheel, and the translation mechanism is used to drive the two float rings away from or towards each other; a baffle plate, on the side of the protective cover near the primary slitting wheel, a side groove is provided, and the baffle plate covers the side groove; the output of the translation mechanism is connected to the baffle plate, and the output of the translation mechanism passes through the side groove and extends to the outside of the protective cover.

[0008] Preferably, the device also includes a base, which is fixedly mounted to the bottom of the protective cover, and the translation mechanism is mounted on the base.

[0009] Preferably, the translation mechanism includes a fixed middle plate, which is fixedly installed at the top center of the base. A fixed end plate is fixedly installed at the top of each of the two ends of the base. A stud is rotatably installed between each of the two fixed end plates and the fixed middle plate.

[0025] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0026] like Figures 1-6 As shown, the primary slitting wheel adjustment mechanism includes a protective cover 4; it also includes: The translation mechanism is installed inside the protective cover 4, and the output part of the translation mechanism is connected to two connecting plates 3. Each of the two connecting plates 3 is fixedly connected to a floating ring 2. The two floats 2 are respectively fitted onto the two ends of the primary cutting wheel 1, and the translation mechanism is used to drive the two floats 2 to move away from each other or closer to each other; The shield 6 has a side groove 401 on the side of the protective cover 4 near the primary cutting wheel 1, and the shield 6 covers the side groove 401. The output of the translation mechanism is connected to the baffle plate 6, and the output of the translation mechanism passes through the side groove 401 and extends to the outside of the protective cover 4.

[0027] There are two side slots 401 and two baffle plates 6. The two baffle plates 6 cover the two side slots 401 respectively, and the length of the baffle plate 6 is greater than the length of the side slot 401. With the above design, the baffle plate 6 moves together with the output part of the translation mechanism, always completely blocking the side slot 401, thereby always ensuring the sealing of the side slot 401.

[0028] like Figure 1 and Figure 6 As shown, as a specific technical solution, it also includes a base 5, which is fixedly installed on the bottom of the protective cover 4, and the translation mechanism is installed on the base 5. The protective cover 4 has a side groove 401 on one side and an opening at the bottom, while other parts are closed; the base 5 is used to close the bottom of the protective cover 4, and at the same time, the base 5 provides an installation position for the translation mechanism.

[0029] like Figure 6 As shown, as a specific technical solution, the translation mechanism includes a fixed middle plate 12, which is fixedly installed at the top center of the base 5. A fixed end plate 13 is fixedly installed at the top of each end of the base 5. A stud 14 is rotatably installed between each of the two fixed end plates 13 and the fixed middle plate 12. The two studs 14 are fixedly connected, and a movable nut seat 15 is threaded onto each of the two studs 14. A movable plate 7 is fixedly installed on one side of each of the two movable nut seats 15. The two movable plates 7 pass through the two side grooves 401 respectively, and the two movable plates 7 are fixedly connected to the two connecting plates 3 respectively.

[0030] The two movable plates 7 serve as the two output parts of the translation mechanism and are connected to the two connecting plates 3, as follows: Figure 5 As shown, the connecting plate 3 and the movable plate 7 are fixed together by bolts and nuts.

[0031] The side groove 401 is the output part of the translation mechanism (i.e., the movable plate 7) that extends out from the protective cover 4 to provide a position. The movable plate 7 extends out from the protective cover 4 and is used to connect and fix with the structure outside the protective cover 4.

[0032] like Figure 6 As shown, as a specific technical solution, multiple guide rods 16 are fixedly installed on both sides of the fixed middle plate 12, which are arranged parallel to the studs 14. The guide rods 16 are slidably sleeved with guide holes opened on the movable nut seat 15. The sliding between the guide rods 16 and the guide holes provides guidance for the movement of the movable nut seat 15.

[0033] The two studs 14 have opposite thread directions, and an input shaft 8 is fixedly mounted on one end of each stud 14.

[0034] The input shaft 8 is connected to an external drive component, such as a motor. The motor drives the two studs 14 to rotate synchronously. The studs 14 and the movable nut seat 15 are driven by threads. With the guidance provided by the guide rod 16 and the guide hole, the movable nut seat 15 moves along the length of the guide rod 16. The threads of the two studs 14 are turned in opposite directions, so the two movable nut seats 15 move in opposite directions, specifically moving closer to each other or further away from each other.

[0035] As the movable nut seat 15 moves, it drives the float ring 2 to move through the movable plate 7 and the connecting plate 3, so that the two float rings 2 move closer or further apart; thereby controlling and adjusting the distance between the two float rings 2 to adjust the inner and outer positions of the cigarette group, so that the cigarette group is aligned and neatly arranged.

[0036] like Figures 3-4 As shown, as a specific technical solution, each of the two shielding plates 6 is provided with a sleeve 11, and the two sleeves 11 are respectively fitted into the two movable plates 7.

[0037] The movable plate 7 is provided with multiple clamping components, which abut against the baffle plate 6. This ensures that the baffle plate 6 fits tightly against the side surface of the protective cover 4 where the side groove 401 is located.

[0038] The clamping assembly includes a fixed base 9, which is fixedly installed on the surface of the movable plate 7. A spring 10 is fixedly connected to the fixed base 9, and the end of the spring 10 away from the fixed base 9 abuts against the baffle plate 6. The spring 10 is in a compressed state.

[0039] The fixed base 9 is an L-shaped plate, and the fixed base 9 is fixedly connected to the surface of the movable plate 7 by screws.

[0040] The baffle plate 6 is used to block the side groove 401 to prevent dust and foreign objects from entering the protective cover 4 through the side groove 401, ensuring the protective effect of the protective cover 4 on its internal components, and preventing dust from entering between the stud 14 and the movable nut seat 15, which would affect the threaded transmission of the two.

[0041] The baffle plate 6 can move together with the movable plate 7 without affecting the movement of the movable plate 7 to the connecting plate 3 and the float ring 2 to adjust the position of the float ring 2. It should be noted that the baffle plate 6 has sufficient length on both sides. The baffle plate 6 moves together with the movable plate 7 and can always cover the side groove 401, ensuring that the protective cover 4 is always in a closed state.

[0042] The clamping component provides pressure to the baffle plate 6, making the baffle plate 6 fit tightly against the protective cover 4, avoiding gaps between the two and ensuring the sealing effect.

[0043] This utility model is not limited to the above-described embodiments. Any changes in its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
