[0030] In the embodiment of the present application, the material on the conveyor belt is placed in the space between the baffles 20. The multiple baffles 20 are preferably arranged at equal intervals. The spring piece 30 is detachably connected to the belt body 10, so that it can be replaced separately at any time. The above-mentioned spring pieces 30 are arranged at both ends of the baffle 20, which can reduce the bending, wear and deformation of the baffle 20 and other structural parts on the composite filter rod forming unit when friction occurs. The spring piece 30 can be bonded to the baffle 20 by PU structural adhesive. Generally, the material of the belt body 10 is PU, and the material of the spring piece 30 can be 301 high-rebound stainless steel.

[0031] The conveyor belt of the embodiment of the present application is provided with spring pieces 30 at both ends of the baffle 20, and the spring pieces 30 are detachably connected to the main body 10, which can improve the local rigidity of the baffle 20, and the spring pieces 30 can be replaced separately, thereby reducing the fragility of the baffle 20 when rubbing against other structural parts on the composite filter rod forming unit, delaying the time when the baffle 20 wears and deforms, extending the service life of the conveyor belt, reducing the number of times the composite filter rod forming unit is shut down for replacement, and improving the production capacity of the composite filter rod forming unit.

[0032] In some embodiments, the conveyor belt also includes a connecting component 40, which can detachably connect the main body 10 and the spring piece 30; the connecting component 40 includes a driving mechanism, a positioning block and a reset mechanism, the positioning block extends from the spring piece 30 into the main body 10, the driving mechanism is connected to the positioning block so that the positioning block enters the main body 10 or moves out of the main body 10, and the reset mechanism is arranged between the spring piece 30 and the positioning block so that the positioning block is stuck in the main body 10.

[0033] In the embodiment of the present application, the driving mechanism drives the positioning block into the main body 10 by connecting with the positioning block. At this time, the reset mechanism is reset to make the positioning block stuck in the main body 10, thereby realizing the connection between the spring piece 30 and the belt body 10; when removing the connecting component 40, the driving mechanism drives the positioning block to separate from the main body 10, so that the reset mechanism is in a compressed state, and the positioning block is taken out from the main body 10, thereby realizing the disassembly of the spring piece 30 and the main body 10.

[0034] The specific structures of the driving mechanism, the positioning block and the reset mechanism can be set differently as needed. In some embodiments, the driving mechanism includes a central shaft 41, a gear 42, an upper rack 43 and a lower rack 44, the output end of the central shaft 41 is connected to the gear 42; the positioning block includes a first positioning block 45 and a second positioning block 46, the upper rack 43 is connected to the first positioning block 45, and the lower rack 44 is connected to the second positioning block 46; the gear 42 is respectively engaged with the upper rack 43 and the lower rack 44 to adjust the distance between the first positioning block 45 and the second positioning block 46.

[0035] Reference Figure 2 The upper rack 43 is connected to the first positioning block 45 on the left side to drive the first positioning block 45 to move. The lower rack 44 is connected to the second positioning block 46 on the right side to drive the second positioning block 46 to move. The gear 42 is meshed with the upper rack 43 and the lower rack 44 respectively. Under the action of the central shaft 41 and the gear 42, the upper rack 43 and the lower rack 44 respectively drive the first positioning block 45 and the second positioning block 46 to approach or move away, thereby realizing the positioning block entering into the body 10 or being taken out of the body 10. The driving mechanism of the gear 42 and the rack has a simple structure, good stability, and is easy to disassemble.

[0036] Specifically, the bottom end of the spring sheet 30 forms a first cavity, and the driving mechanism is placed in the first cavity; the side wall of the spring sheet 30 forms a through slot, which is connected to the first cavity, and the lower rack 44 extends from the first cavity through the through slot. In the embodiment of the present application, placing the driving mechanism in the first cavity in the spring sheet 30 can protect the driving mechanism from external influences and ensure its function. The lower rack 44 extends from the first cavity through the through slot, and the distance between the first positioning block 45 and the second positioning block 46 can be controlled by pressing the lower rack 44 to reduce the distance between the first positioning block 45 and the second positioning block 46 so that the two are close to each other, thereby removing the first positioning block 45 and the second positioning block 46 from the body 10.

[0037] In some embodiments, the connecting assembly 40 also includes a fixed shaft 47, one end of which is fixed to an inner wall of the first cavity, and the other end passes through the first positioning block 45 and the second positioning block 46 and is fixed to the other opposite inner wall of the first cavity, and the fixed shaft 47 is movably connected to the first positioning block 45 and the second positioning block 46 respectively; the reset mechanism includes an elastic member, and the two ends of the fixed shaft 47 are respectively sleeved with the elastic members, one end of the elastic member abuts against the inner wall of the first cavity, and the other end abuts against the first positioning block 45 or the second positioning block 46.

[0038] Reference Figure 2 The fixed shaft 47 is fixed in the first cavity of the spring sheet 30, and the fixed shaft 47 passes through the positioning block, and the two positioning blocks are movably connected by means of a hole sleeve. Both ends of the fixed shaft 47 are sleeved with elastic members. In addition to abutting against the inner wall of the first cavity, the elastic member also abuts against the positioning block at the same time. Therefore, when the positioning block moves, the elastic member will change the state of compression or extension, and when the elastic member is reset, the positioning block will also be reset. Among them, the elastic member can be a spring 48.

[0039] Furthermore, a connecting groove and a positioning groove are formed at the upper end of the main body 10. The size of the connecting groove is smaller than that of the positioning groove. The first positioning block 45 and the second positioning block 46 are respectively provided with step portions. The first positioning block 45 and the second positioning block 46 are respectively extended into the positioning groove through the connecting groove so that the step portion abuts against the inner wall of the positioning groove.

[0040] In the embodiment of the present application, the size of the connecting groove is smaller than that of the positioning groove. Figure 2 The connection groove and the positioning groove are square cavities, and their dimensions refer to the length and width of the cavities. The depth of the connection groove and the positioning groove is adjusted according to the size of the positioning block. The first positioning block 45 and the second positioning block 46 are both provided with a step portion, and when the two are close, they can extend into the positioning groove, and then the distance between the two positioning blocks is increased, and they are respectively abutted against the inner wall of the positioning groove, so as to realize the clamping connection between the positioning block and the body 10.

[0041] In some embodiments, the baffle 20 includes a plurality of baffles 21, and adjacent baffles 21 are detachably connected. Figure 1In the embodiment of the present application, the baffle 20 is composed of a plurality of baffles 21, and the number of baffles 21 can be adapted according to the specifications of the belt body 10. The detachable setting between the baffle 21 and the belt body 10 enables independent replacement of any baffle 21 when it is severely worn and deformed, and the baffle 21 can be disassembled and recycled when the belt body 10 cannot be used, thereby avoiding waste of resources.

[0042] Specifically, a locking groove 211 is provided on the block 21, and a through hole 212 is formed on the side wall of the locking groove 211 near the adjacent block 21; the baffle 20 also includes a connecting piece, and the connecting piece extends from one block 21 through the through hole 212 into the locking groove 211 to connect the adjacent block 21. In the embodiment of the present application, the connecting piece connects two adjacent blocks 21. The connecting piece extends from one block 21 through the through hole 212 of the adjacent block 21 into the locking groove 211, thereby locking the two adjacent blocks 21. Specifically, the connecting piece includes a screw 213 and a nut 214, the screw 213 extends through the through hole 212 into the locking groove 211, and the nut 214 is locked on the screw 213 in the locking groove 211.

[0043] In the embodiment of the present application, the method for disassembling and assembling the spring piece 30 and the belt body 10 is as follows: press the lower rack 44, drive the two positioning blocks to approach each other through the driving mechanism, make the two positioning blocks separate from the positioning area of ​​the positioning groove, lift the spring piece 30, make the two positioning blocks move out of the connecting groove and out of the body 10, and then the spring piece 30 and the belt body 10 can be disassembled. The spring piece 30 is bonded to the baffle 20, and the baffle 20 and the belt body 10 can be separated by lifting the two spring pieces 30. In addition, by pressing the lower rack 44, the two positioning blocks are driven to approach each other through the driving mechanism, and the spring 48 is stretched at this time until the two positioning blocks can extend into the connecting groove and then into the positioning groove; the external force pressing the lower rack 44 is cancelled, and the stretched spring 48 loses resistance and can be reset, and the two positioning blocks are pulled toward the inner wall of the positioning groove until the positioning blocks abut against the inner wall of the positioning groove, thereby realizing the installation of the spring piece 30 and the belt body 10; after the spring pieces 30 at both ends of the baffle 20 are installed, the baffle 20 and the belt body 10 can be installed.
