Description

Technical Field

[0001] This application relates to the field of cigarette product prototyping technology, and in particular to an automated experimental device for the production of multi-component composite filter rods. Background Technology

[0002] Traditional cigarette filters are primarily made of cellulose acetate, but with technological advancements, the types and functions of filters have undergone significant changes. For example, there are activated carbon composite filter rods, plant fiber filter rods, non-toxic chemical fiber filter rods, high-carbon filter rods, magnetic material filter rods, hollow filter rods, and menthol-type filter rods. These are all filter types developed based on different filtration needs and technological innovations. Furthermore, filter rods of different materials and structures can be combined into a single filter to improve cigarette flavor, enhance filtration efficiency, and reduce harm to human health.

[0003] However, before these diverse filter tips can be mass-produced, it is often necessary to select a suitable process for prototyping and to conduct performance tests on the samples to determine whether they are suitable for mass production. There are generally two existing processes: one is the cigarette holder forming process, and the other is the twisting process. The cigarette holder forming process refers to rolling a filter paper with multiple filter rods, and then cutting the filter paper and filter rods into multiple finished filter rods at the same time. The twisting process refers to cutting a filter paper into multiple filter papers of the same length as the combined multi-element filter rods, and then twisting each filter paper with a single multi-element filter rod to form a finished filter rod.

[0004] However, when prototyping multi-component filter rods, existing large-scale mass production machines are usually modified. This modification is time-consuming, and the modified machines are highly specialized, only capable of prototyping one type of filter rod: binary, ternary, or quaternary composite. They cannot achieve multi-component filter rod prototyping and can only use one process for prototyping. This high degree of specialization makes them unsuitable for experimental prototyping of various multi-component filter rods. Therefore, existing prototyping equipment has low efficiency and poor adaptability, making it unsuitable for dedicated experimental prototyping. Summary of the Invention

[0005] In order to realize the prototyping of diversified filter rods, improve prototyping efficiency, and provide strong support for the rapid development and prototyping of new products, this application provides an automated experimental equipment for the production of multi-component composite filter rods.

[0006] The experimental equipment for automatic production of multi-component composite filter rods provided in this application adopts the following technical solution: An automated production experimental device for multi-component composite filter rods includes an experimental platform, a first material collection assembly, a filter rod slitting assembly, a second material collection assembly, a first conveyor belt, a winding assembly, an unwinding assembly, a cutting assembly, a filter paper slitting assembly, a positioning and gluing assembly, a finished product slitting assembly, a first collection box, and a second collection box. The first collection assembly is provided in several units, which are used to store different types of filter rods and can transport the filter rods one by one to the filter rod cutting assembly. The filter rod cutting assembly is provided in several parts, and each filter rod cutting assembly corresponds to the first material collection assembly. The filter rod cutting assembly is used to cut the filter rod into a specified size and transport the cut filter rod to the second material collection assembly. The second material collection component is provided in several parts, and the second material collection component corresponds one to one with the filter rod cutting component. The second material collection component is used to store the cut filter rods and can transport the cut filter rods one by one to the first conveyor belt. The first conveyor belt is used to transport the filter rods to the winding component. The unwinding assembly is used to unwind the filter paper to the cutting assembly, the cutting assembly is used to cut the filter paper to a suitable width so that the filter paper can just wrap around the circumference of the filter rod, and the unwinding assembly transports the cut filter paper to the filter paper slitting assembly. The filter paper cutting assembly is used to cut the filter paper to a suitable length so that the length of each filter paper is exactly the same as the length of the multi-element filter rod. The filter paper cutting assembly is used to transport the cut filter paper to the positioning and coating assembly. The positioning and gluing assembly is used to transport the filter paper to the designated position of the winding assembly and apply glue to the filter paper fasteners. The winding assembly is used to wind the filter paper and filter rod together and transport them. If the filter paper has been cut by the filter paper cutting component before winding, the winding component will transport the wound filter rod to the first collection box. If the filter paper is not cut by the filter paper slitting component before winding, the winding component will transport the wound filter rod to the finished product slitting component, which will then cut the wound filter rod into multiple finished multi-element filter rods and transport them to the second collection box.

[0007] By adopting the above technical solution, filter rods of different materials can be placed into different first collection components. According to the needs of the sample product, the filter rods in the corresponding first collection components are discharged to the filter rod cutting component for cutting. After cutting, they are transported to the second collection component. Then, according to the combination sequence of the multi-element filter rods, the corresponding second collection component discharges one filter rod at a time to the first conveyor belt, which then transports it to the winding component. The unwinding component unwinds the filter paper, and the cutting component cuts the filter paper to a suitable width. Then, the next step of production is carried out according to the selected process. If the cigarette holder forming process is selected, the filter paper is only conveyed by the filter paper slitting component without being slitted. The filter paper slitting component transports the filter paper to the positioning and gluing component, which then transfers the filter paper to the designated position of the winding component for gluing. The winding component then winds the filter rod and filter paper together. At this time, multiple multi-element filter rods are wound together within one sheet of filter paper. The wound paper is then conveyed to the finished product slitting component to be cut into multiple finished multi-element filter rods and transported to the second collection box for collection. If the twisting and forming process is selected, the filter paper is cut into several filter papers of the same length as a single multi-element combination filter rod by the filter paper cutting component. Then, the positioning and gluing component transfers the filter paper to the designated position of the winding component for gluing. The winding component can then wind the filter rod and filter paper together and transport them directly to the first collection box for collection. This equipment can produce samples of binary, ternary, quaternary, and even multi-element filter rods. It can also select the sample manufacturing process according to the actual production process, making it highly adaptable and efficient in producing samples.

[0008] Optionally, the first material collection assembly includes a first hopper and a first locking feed roller. The first locking feed roller is adapted to the outlet of the first hopper. The circumferential surface of the first locking feed roller is provided with a plurality of first receiving grooves along its length. Each first receiving groove can only accommodate one filter rod at a time, and only one receiving groove of the first locking feed roller leaves the outlet of the first hopper at a time.

[0009] By adopting the above technical solution, during material discharge, the motor drives the first locking feed roller to rotate at a specified angle, so that the first locking feed roller only delivers one filter rod at a time.

[0010] Optionally, the filter rod cutting assembly includes a first receiving plate located below the discharge port of the first hopper. The first receiving plate has a first positioning groove, and a first support plate is hinged to one end of the first receiving plate. The first support plate is driven by a motor to swing up and down. The first support plate is located above the feed end of the second collecting assembly. The first support plate has a plurality of first cutting grooves along its width direction. A first adjusting component is provided on the experimental table. A plurality of first cutting blades are installed on the first adjusting component. The first adjusting component is raised and lowered by an electric cylinder. The first receiving plate is provided with a first reciprocating component and a first clamping component. The first clamping component is used to hold the two ends of the filter rod that falls into the first positioning groove. The first reciprocating component is used to simultaneously transport the first clamping component and the filter rod to the first support plate. The first adjusting component is used to adjust the plurality of first cutters to a suitable spacing.

[0011] By adopting the above technical solution, the filter rod discharged from the first hopper falls into the first positioning groove. Then, the first clamping member clamps the filter rod, and the first reciprocating member drives the filter rod to move onto the first support plate and align the filter rod with the first cutter. Then, the first adjusting member adjusts the spacing of the first cutter and controls the first cutter to fall and cut. After cutting, the first clamping member resets, and the first support plate rotates to make the filter rod roll into the second collection assembly. The first cutters on both sides can be adjusted to the sides of the support plate to achieve bi-splitting of the filter rod, or the first cutters can be aligned with the corresponding first cutting grooves to achieve multi-splitting of the filter rod. The first clamping member can reduce the possibility of filter rod misalignment, allowing the filter rod to be accurately cut and shaped.

[0012] Optionally, the second material collection assembly includes a second hopper and a second locking feed roller. The second locking feed roller has a plurality of second receiving grooves opened on its circumferential surface along its length direction. The second locking feed roller has the same structure as the first locking feed roller. Length adjustment side plates are provided on both sides of the second hopper. The length adjustment side plates pass through the second hopper and are driven to move by a cylinder. The two length adjustment side plates are each located above both ends of the second locking feed roller.

[0013] By adopting the above technical solution, the distance between the two length adjustment side plates is adjusted according to the different lengths of the filter rods after cutting, so that only one filter rod of different lengths can fall into the second receiving trough each time.

[0014] Optionally, the first conveyor belt is located below the discharge ports of several second hoppers. The winding assembly includes a winding box containing winding fabric, a winding roller, a tension plate, and several support rollers. The winding fabric is wound around the winding fabric, the winding roller, the tension plate, and the support rollers. The top surface of the winding fabric forms a winding surface, a concave surface, and a raised surface. At least two support rollers support the winding surface. The winding roller is higher than the support rollers and supports the raised surface. The portion of the winding fabric between the winding roller and the adjacent support roller is subjected to gravity. The concave surface is formed by the material being fed into the roll-up box, with the first conveyor belt directly opposite the feeding hole. The feeding hole is directly opposite the groove formed by the concave surface. An adjusting roller is rotatably connected inside the box, and a tensioning plate is connected to the adjusting roller. The adjusting roller is driven to rotate by the motor. The box is equipped with a reciprocating component for moving the roll-up roller along the length of the top surface of the roll-up fabric. A lifting plate is provided on the box, driven by an electric cylinder. Material guide plates are provided at both ends of the lifting plate, and the two material guide plates are respectively positioned opposite to the two ends of the concave surface.

[0015] By adopting the above technical solution, multiple types of filter rods are conveyed to the concave surface of the winding cloth via the first conveyor belt. Then, the material guide plate descends, and the two treatment plates abut against the end faces of the two outermost filter rods, thereby adjusting the position of multiple filter rods so that they abut against each other and are centered. After the filter paper is placed at the end of the winding surface away from the raised surface, the reciprocating component drives the winding roller to move towards the winding surface, thereby the winding cloth drives the filter rod to roll to the filter paper for winding. During the movement of the winding roller, the winding cloth gradually tightens. After winding, the winding cloth pops out the wound filter rod. By rotating the adjusting roller, the abutment state of the tension plate against the winding cloth can be changed, thus enabling the winding of filter rods with different outer diameters, making it highly applicable.

[0016] Optionally, the cutting assembly includes a cam, a control shaft, a first cutting plate, and a second cutting plate. The cam is driven by a motor. The control shaft is rotatably connected to the experimental platform. A first connecting plate and a second connecting plate are symmetrically arranged on the circumference of the control shaft. The first connecting plate abuts against the circumference of the cam. The second connecting plate is hinged to a first connecting rod. The first connecting rod is connected to a first moving plate. The first moving plate is connected to a second connecting rod. The first cutting plate is fixed on the experimental platform. The second connecting rod passes through the first cutting plate and is connected to the second cutting plate. The first cutting plate is provided with a second cutting blade. The second cutting plate has a second cutting groove. The unwinding assembly includes an unwinding roller and a guide roller. The finished filter paper is wound around the unwinding roller, passes around the guide roller, and passes between the first cutter and the second cutter.

[0017] By adopting the above technical solution, the unwinding roller and the guide roller unwind the filter paper. The cam rotates and drives the first connecting plate to move. The first connecting plate drives the control shaft to rotate. The control shaft drives the second connecting plate to move away from the first cutting plate. The second connecting plate pulls the first connecting rod to move the first moving plate away from the first cutting plate. The first moving plate pulls the second connecting rod to move the second cutting plate closer to the first cutting plate. Then, the second cutter is inserted into the second cutting groove to cut the filter paper.

[0018] Optionally, the filter paper slitting assembly includes several second conveyor belts, a first pressure roller, and a second pressure roller. A cutting space is left between adjacent second conveyor belts. A second adjusting component is provided on the experimental platform. Several third cutters are installed on the second adjusting component. The third cutters are located above the second conveyor belts. The second adjusting component is used to adjust the several third cutters to a suitable spacing. The second adjusting component is raised and lowered by an electric cylinder. The first pressure roller and the second pressure roller are both arranged along the width direction of the second conveyor belt and are in contact with all the second conveyor belts. The third cutters are located between the first pressure roller and the second pressure roller.

[0019] By adopting the above technical solution, the filter paper is cut to a suitable width and falls onto multiple second conveyor belts. The second adjusting component first drives the third cutting groove to be inserted into the cutting space and rotates. The multiple second conveyor belts simultaneously drive the filter paper to the first pressure roller. The first pressure roller presses the filter paper, and the third cutter cuts the filter paper. After one end of the filter paper is cut, it passes through the second pressure roller. The cooperation of the first pressure roller and the second pressure roller enables the filter paper to be accurately cut into several segments.

[0020] Optionally, the positioning and gluing assembly includes a lifting seat located above the roll-to-roll box. The lifting seat is driven by an electric cylinder and is equipped with a lateral adjustment component connected to a pressure block. A connecting plate is provided on the lifting seat, which can connect with the roll-to-roll surface of the roll-to-roll fabric. The lateral adjustment component can drive the pressure block to rise and fall and move the pressure block along the length direction of the lifting seat. The lifting seat is also equipped with a longitudinal adjustment component, which is equipped with a cold glue sprayer. The longitudinal adjustment component is used to drive the cold glue sprayer to move along the width and length directions of the lifting seat.

[0021] By adopting the above technical solution, the filter paper is conveyed from the second conveyor belt to the connecting plate, and then the pressure block presses the filter paper. The lifting seat descends to connect the connecting plate with the roll-up surface of the roll-up cloth. The transverse adjustment component drives the pressure block to move, and the pressure block drags the filter paper to the designated position on the roll-up surface. Then, the longitudinal adjustment component drives the cold glue sprayer to the overlap, and the longitudinal adjustment component then drives the cold glue sprayer to move along the length of the filter paper to spray glue, thereby realizing the automatic positioning and glue spraying of the filter paper.

[0022] Optionally, the bottom of the winding box is provided with a discharge port at the end away from the tensioning plate. The winding box is equipped with a first sealing plate and a second sealing plate. Both the first sealing plate and the second sealing plate are driven by an electric cylinder. The first sealing plate and the second sealing plate together close the discharge port. When the first sealing plate is open and the second sealing plate is closed, the discharge port is connected to the finished product cutting assembly; When the first sealing plate is closed and the second sealing plate is open, the discharge port is connected to the first collection box.

[0023] By adopting the above technical solution and adjusting the opening and closing states of the first and second sealing plates, filter rods produced by two different manufacturing processes, namely cigarette gun forming and twisting forming, can be collected separately.

[0024] Optionally, the finished product slitting assembly includes a second receiving plate, which is connected to the discharge end of the coiling assembly. The second receiving plate has a second positioning groove. A second support plate is hinged to the end of the second receiving plate away from the coiling assembly. The second support plate is driven by a motor to swing up and down. The second support plate is located above the feeding end of the second collection box. The second support plate has several third cutting grooves along its width direction. A third adjusting component is provided on the experimental table. Several fourth cutting blades are installed on the third adjusting component. The third adjusting component is raised and lowered by an electric cylinder. The second receiving plate is provided with a second reciprocating component and a second clamping component. The second clamping component is used to hold the two ends of the filter rod that falls into the second positioning groove. The second reciprocating component is used to simultaneously transport the second clamping component and the filter rod to the second support plate. The third adjusting component is used to adjust the plurality of the fourth cutters to a suitable spacing.

[0025] By adopting the above technical solution, the filter rod formed by the cigarette gun is transported out from the cigarette box and falls on the second positioning groove of the second receiving plate. Then, the second clamping member clamps the filter rod, and the reciprocating member drives the second clamping member and the filter rod to move to the second support plate. The third adjusting member controls the fourth cutter to descend and cut the filter rod, forming multiple multi-element composite filter rods.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. This equipment can produce samples of binary, ternary, quaternary and even multi-element filter rods. At the same time, the sample manufacturing process can be selected according to the actual production process. It is highly adaptable and has high sampling efficiency. 2. To achieve multi-segment cutting of the filter rod, the first clamping component can reduce the occurrence of filter rod misalignment, so that the filter rod can be accurately cut into shape; 3. Multiple second conveyor belts simultaneously drive the filter paper to the first pressure roller. The first pressure roller presses the filter paper, and the third cutter cuts the filter paper. After one end of the filter paper is cut, it passes through the second pressure roller. The first and second pressure rollers work together to ensure that the filter paper can be accurately cut into several segments. 4. The filter paper is conveyed from the second conveyor belt to the connecting plate, and then the pressure block presses the filter paper. The lifting seat descends to connect the connecting plate with the roll-up surface of the roll-up cloth. The transverse adjustment component drives the pressure block to move, and the pressure block drags the filter paper to the designated position on the roll-up surface. Then the longitudinal adjustment component drives the cold glue sprayer to the overlap. The longitudinal adjustment component then drives the cold glue sprayer to move along the length of the filter paper to spray glue, realizing automatic positioning and glue spraying of the filter paper.

[0037] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0038] This application discloses an automated experimental device for producing multi-component composite filter rods.

[0039] like Figure 1 and Figure 2 The experimental equipment for automatic production of multi-component composite filter rods includes an experimental table 1, a first material collection assembly 2, a filter rod slitting assembly 3, a second material collection assembly 4, a first conveyor belt 11, a winding assembly 5, an unwinding assembly 6, a cutting assembly 7, a filter paper slitting assembly 8, a positioning and gluing assembly 9, a finished product slitting assembly 10, a first collection box 12, and a second collection box 13. The first collection component 2 is provided in four parts. The four first collection components 2 are installed on the experimental table 1 and are arranged at equal intervals along the length of the experimental table 1. The four first collection components 2 are used to store different types of filter rods and can transport the filter rods one by one to the filter rod cutting component 3. There are four filter rod cutting components 3. Each filter rod cutting component 3 corresponds to one of the first collection components 2. The filter rod cutting components 3 are located below the first collection components 2. The filter rod cutting components 3 are used to cut the filter rods into specified sizes and transport the cut filter rods to the second collection components 4. There are four second material collection components 4. Each second material collection component 4 corresponds to one of the filter rod cutting components 3. The second material collection components 4 are located below the filter rod cutting components 3. The second material collection components 4 are used to store the cut filter rods and can transport the cut filter rods one by one to the first conveyor belt 11. The first conveyor belt 11 is set along the length of the experimental table 1 and is located below the second material collection components 4. The first conveyor belt 11 is used to transport the filter rods to the winding and splicing components 5. The unwinding assembly 6 is used to unwind the filter paper to the cutting assembly 7. The cutting assembly 7 is used to cut the filter paper to a suitable width so that the filter paper can just wrap around the circumference of the filter rod. The unwinding assembly 6 transports the cut filter paper to the filter paper slitting assembly 8. The filter paper cutting assembly 8 is used to cut the filter paper to a suitable length so that the length of each filter paper is exactly the same as the length of the multi-element filter rod. The filter paper cutting assembly 8 is used to transport the cut filter paper to the positioning and gluing assembly 9. The positioning and gluing assembly 9 is located above the winding assembly 5. The positioning and gluing assembly 9 is used to transport the filter paper to the designated position of the winding assembly 5 and apply glue to the filter paper fastener. The winding assembly 5 is used to wind the filter paper and filter rod together and transport them. If the filter paper has been cut by the filter paper cutting component 8 before winding, the winding component 5 will transport the wound filter rod to the first collection box 12. If the filter paper is not cut by the filter paper slitting component 8 before winding, the winding component 5 transports the wound filter rod to the finished product slitting component 10. The finished product slitting component 10 is located below the filter paper slitting component 8. The finished product slitting component 10 cuts the wound filter rod into multiple finished multi-element filter rods and transports them to the second collection box 13.

[0040] The experimental platform 1 is equipped with a human-computer interaction screen 14 for adjusting the data of each component.

[0041] During the sampling process, filter rods of different materials are first placed into different first collection components 2. According to the needs of the sampled product, the filter rods in the corresponding first collection components 2 are discharged to the filter rod cutting component 3 for cutting. After cutting, they are transported to the second collection component 4. Then, according to the combination sequence of the multi-element filter rods, the corresponding second collection component 4 discharges one filter rod at a time to the first conveyor belt 11, and then the first conveyor belt 11 transports it to the winding component 5 to wait for winding. While the filter rod is being cut and transported, the unwinding assembly 6 unwinds the filter paper, and the cutting assembly 7 cuts the filter paper to the appropriate width before proceeding to the next production step according to the selected process. If the cigarette gun forming process is selected, the filter paper is only conveyed by the filter paper slitting component 8 without being slitted. The filter paper slitting component 8 transports the filter paper to the positioning and gluing component 9. The positioning and gluing component 9 transfers the filter paper to the designated position of the winding component 5 for gluing. Then the winding component 5 can wind the filter rod and the filter paper together. At this time, multiple multi-element filter rods are wound inside one filter paper. The wound filter rod is conveyed to the finished product slitting component 10 to be cut into multiple finished multi-element filter rods and transported to the second collection box 13 for collection. If the twisting and forming process is selected, the filter paper is cut into several filter papers of the same length as a single multi-element combination filter rod by the filter paper cutting component 8. Then, the positioning and gluing component 9 transfers the filter paper to the designated position of the winding component 5 for gluing. Then, the winding component 5 can wind the filter rod and filter paper together and transport them directly to the first collection box 12 for collection. This equipment can produce samples of binary, ternary, quaternary, and even multi-element filter rods. It can also select the sample manufacturing process according to the actual production process, making it highly adaptable and efficient in producing samples.

[0042] like Figure 3The first material collection assembly 2 includes a first hopper 21 and a first locking feed roller 22. The first locking feed roller 22 is adapted to the outlet of the first hopper 21. The diameter of the outlet of the first hopper 21 is 2-5mm larger than the diameter of the filter rod, thus ensuring that only one filter rod passes through the outlet of the first hopper 21 at a time. The inner wall of the first hopper 21 is inclined to connect with the outlet of the first hopper 21. The first locking feed roller 22 has four first receiving grooves 221 evenly spaced along its circumference. Each first receiving groove 221 is along the first locking feed roller 22. The feeding roller 22 extends along its length to both ends of the first locking feeding roller 22. The inner diameter of the first receiving groove 221 is 2-5mm larger than the diameter of the filter rod, ensuring that the first receiving groove 221 can accommodate only one filter rod at a time and can accommodate filter rods with different inner diameters. When one of the first receiving grooves 221 faces downward away from the discharge port of the first hopper 21, two of the first receiving grooves 221 face the side wall of the discharge port of the first hopper 21, and one of the first receiving grooves 221 faces upward directly towards the discharge port of the first hopper 21. A motor is installed on the first hopper 21, and the motor is coaxially connected to the first locking feeding roller 22. During discharge, the motor drives the first locking feeding roller 22 to rotate 90 degrees each time, so that the first locking feeding roller 22 delivers only one filter rod at a time.

[0043] like Figure 3 and Figure 4 The second material collection assembly 4 includes a second hopper 41 and a second locking feed roller 42. The size of the second hopper 41 is smaller than that of the first hopper 21. The first hopper 21 and the second hopper 41 have the same structure. The second locking feed roller 42 has a second receiving groove 421. The structure of the second locking feed roller 42 is the same as that of the first locking feed roller 22. The second hopper 41 has length adjustment side plates 43 on both sides, which pass through the second hopper 41. Cylinders are installed on both sides of the second hopper 41, and the cylinders are connected to the length adjustment side plates 43 on the same side. The two length adjustment side plates 43 are located above the two ends of the second locking feed roller 42. The distance between the two length adjustment side plates 43 is adjusted according to the different lengths of the filter rods after cutting, so that only one filter rod of different lengths falls into the second receiving groove 421 each time.

[0044] like Figure 1 and Figure 5The filter rod cutting assembly 3 includes a first receiving plate 31, which is located below the outlet of the first hopper 21. A first positioning groove 311 is formed on the first receiving plate 31, directly opposite the outlet of the first hopper 21. The portion of the conveying surface of the first receiving plate 31 near the first positioning groove 311 is higher than the bottom of the groove, while the remaining portion is flush with the bottom of the groove. The first receiving plate 31 is located away from the first hopper 21. One end of the first support plate 32 is hinged to the first receiving plate 31, and a motor is installed on the first receiving plate 31. The motor is connected to the hinge shaft of the first support plate 32, and the first support plate 32 is driven by the motor to swing up and down. The first support plate 32 is located above the discharge port of the second hopper 41. The first support plate 32 has three first cutting grooves 321 equidistantly opened along its width direction. The experimental table 1 is provided with a first adjusting component 33, and three first cutters 34 are installed on the first adjusting component 33. The first adjusting component 33 is raised and lowered by an electric cylinder. The first adjusting component 33 includes a mounting base, an electric cylinder connected to the mounting base, and the width of the mounting base is greater than the width of the first support plate 32. The mounting base is equidistantly connected to three lead screws along its width direction. The lead screw in the middle is higher than the lead screws on both sides. The lead screws on both sides are bidirectional threaded lead screws. Three movable seats are slidably connected inside the mounting base. One movable seat is threadedly connected to the middle lead screw, and the other two movable seats are threadedly connected to the bidirectional threaded lead screws on both sides. One movable seat is threadedly connected to the positive thread section of the two bidirectional threaded lead screws, and the other movable seat is threadedly connected to the negative thread section of the two bidirectional bolt lead screws. The bottoms of the three movable seats are flush, and each of the three movable seats is equipped with a motor. Each motor is connected to a first cutter 34. The width between the first cutters 34 on both sides can be adjusted to be greater than the width of the first support plate 32, thereby enabling the filter rod to be cut into two or four equal parts.

[0045] The first receiving plate 31 is provided with a first reciprocating member 35 and a first clamping member 36. The first clamping member 36 is used to hold the two ends of the filter rod falling into the first positioning groove 311. The first reciprocating member 35 is used to simultaneously transport the first clamping member 36 and the filter rod to the first support plate 32. The first adjusting member 33 is used to adjust the plurality of first cutters 34 to a suitable spacing. The first reciprocating component 35 includes two cylinders, which are mounted on both sides of the first receiving plate 31. The piston rods of both cylinders are connected to electric cylinders, and the piston rods of the electric cylinders can extend along the width direction of the first receiving plate 31. The electric cylinders are connected to clamping blocks. After the filter rod falls into the first positioning groove 311, the electric cylinders on both sides drive the clamping blocks to clamp the ends of the filter rods. At the same time, the cylinders on both sides are activated to push the electric cylinders to move, thereby moving the filter rods onto the first support plate 32.

[0046] The filter rods discharged from the first hopper 21 fall into the first positioning groove 311. Then, the first clamping member 36 clamps the filter rods, and the first reciprocating member 35 moves the filter rods onto the first support plate 32, aligning the filter rods with the first cutter 34. Then, the first adjusting member 33 adjusts the spacing of the first cutter 34 and controls the first cutter 34 to fall and cut. After cutting, the first clamping member 36 resets, and the first support plate 32 rotates to make the filter rods roll into the second collection assembly 4. The first cutters 34 on both sides can be adjusted to the sides of the first support plate 32 to achieve bi-splitting of the filter rods, or the first cutters 34 can be aligned with the corresponding first cutting grooves 321 to achieve multi-splitting of the filter rods. The first clamping member 36 can reduce the possibility of filter rod misalignment, allowing the filter rods to be accurately cut and shaped.

[0047] like Figure 6 and Figure 7 The first conveyor belt 11 is located below the discharge ports of the four second hoppers 41. The first conveyor belt 11 is set along the length of the experimental platform 1. The width of the first conveyor belt 11 is 2-5 mm greater than the inner diameter of the filter rod. The winding assembly 5 includes a winding box 51, which contains a winding cloth 55, a winding roller 52, a tension plate 53, and four support rollers 54. The winding cloth 55 is wound around the winding roller 52, the tension plate 53, and the four support rollers 54. Two of the support rollers 54 are rotatably connected to the bottom of the winding box 51 and are located at one end of the winding box 51. The other two support rollers 54 support the top surface of the winding cloth 55. The height of roller 2 is higher than the height of support roller 54. The top surface of the fabric 55 forms a winding surface 551, a concave surface 552, and a raised surface 553. Two support rollers 54 support the winding surface 551, and the winding roller 52 supports the raised surface 553. The portion of the fabric 55 between the winding roller 52 and the adjacent support roller 54 forms a concave surface 552 under the action of gravity. An adjusting roller 56 is rotatably connected inside the winding box 51. The adjusting roller 56 is located at the end of the winding box 51 away from the winding surface 551 of the fabric 55. The tension plate 53 is connected to the adjusting roller 56. The adjusting roller 56 is driven to rotate by a motor installed on the winding box 51. The roll-to-roll box 51 is provided with a reciprocating component 57 for driving the roll roller 52 to move along the length of the top surface of the roll fabric 55. The reciprocating component 57 includes rodless cylinders provided on both sides of the roll-to-roll box 51. The side wall of the roll-to-roll box 51 is provided with sliding holes along its length. The roll roller 52 passes through the sliding holes and is rotatably connected to the slider of the rodless cylinder. The roll roller 52 has a built-in heating module, which can heat the roll roller 52 during the hot glue heating process.

[0048] The winding box 51 has a feed hole 511. The first conveyor belt 11 is directly opposite the feed hole 511. The feed hole 511 is directly opposite the slot formed by the concave surface 552. The winding box 51 is provided with a lifting plate 58. The lifting plate 58 is located above the winding box 51 and is directly opposite the concave surface 552. The lifting plate 58 is driven to lift by an electric cylinder. The two ends of the lifting plate 58 are provided with material guide plates 581. The two material guide plates 581 are respectively set opposite to the two ends of the concave surface 552. The opposite side of the two material guide plates 581 can be attached to the inner side wall of the winding box 51. The opposite side of the two material guide plates 581 is set as an inclined surface.

[0049] Multiple types of filter rods are conveyed to the concave surface 552 of the winding cloth 55 via the first conveyor belt 11. Then, the material guide plate 581 descends, and the two material guide plates 581 respectively abut against the end faces of the two outermost filter rods, thereby adjusting the position of multiple filter rods so that they abut against each other and are centered. After the filter paper is placed at the end of the winding surface 551 away from the raised surface 553, the reciprocating component 57 drives the winding roller 52 to move towards the winding surface 551, thereby the winding cloth 55 drives the filter rods to roll to the filter paper for winding. During the movement of the winding roller 52, the winding cloth 55 gradually tightens. After winding, the winding cloth 55 pops out the wound filter rods. By rotating the adjusting roller 56, the abutment state of the tension plate 53 against the winding cloth 55 can be changed, thus enabling the winding of filter rods with different outer diameters, which has high applicability.

[0050] like Figure 6 and Figure 8 The cutting assembly 7 includes a cam 71, a control shaft 72, a first cutting plate 73, and a second cutting plate 74. The cam 71 is driven by a motor. The control shaft 72 is rotatably connected to the experimental table 1. The circumferential surface of the control shaft 72 is symmetrically connected to a first connecting plate 75 and a second connecting plate 76. The first connecting plate 75 abuts against the circumferential surface of the cam 71. The second connecting plate 76 is hinged to a first connecting rod 77. The first connecting rod 77 is connected to a first moving plate 78. The first moving plate 78 is connected to a second connecting rod 79. The first cutting plate 73 is fixed on the experimental table 1. The second connecting rod 79 passes through the first cutting plate 73 and is connected to the second cutting plate 74. The first cutting plate 73 is provided with a second cutting blade 731. The second cutting plate 74 has a second cutting groove 741. The first cutting plate 73 is located above the second cutting plate 74. The first moving plate 78 is located above the first cutting plate 73. The second connecting plate 76 is located above the first moving plate 78. The unwinding assembly 6 includes an unwinding roller 61, a guide roller 62, an active roller 63, and a passive roller 64. The finished filter paper is wound on the unwinding roller 61, passes around the guide roller 62 and passes between the first cutter 73 and the second cutter 74, and then passes between the active roller 63 and the passive roller 64. The active roller 63 is driven by a motor to rotate.

[0051] The unwinding roller 61, in conjunction with the guide roller 62, unwinds the filter paper. The cam 71 rotates, causing the first connecting plate 75 to move. The first connecting plate 75 drives the control shaft 72 to rotate. The control shaft 72 drives the second connecting plate 76 to move away from the first cutting plate 73. The second connecting plate 76 pulls the first connecting rod 77, causing the first moving plate 78 to move away from the first cutting plate 73. The first moving plate 78 pulls the second connecting rod 79, causing the second cutting plate 74 to move closer to the first cutting plate 73. This causes the second cutter 731 to insert into the second cutting groove 741, thereby cutting the filter paper. Before cutting, the filter paper has passed through the active roller 63 and the passive roller 64, so that the filter paper is in a taut state and can be cut smoothly.

[0052] like Figure 6 and Figure 7 The filter paper slitting assembly 8 includes four second conveyor belts 81, a first pressure roller 82, and a second pressure roller 83. The four second conveyor belts 81 are arranged equidistantly along the length of the test bench, with a cutting space between adjacent second conveyor belts 81. A second adjusting member 84 is installed on the test bench 1, and the second adjusting member 84 is equipped with three third cutters 85. The third cutters 85 are located above the second conveyor belts 81. The second adjusting member 84 is used to adjust the spacing of the third cutters 85 to a suitable distance. The second adjusting member 84 is raised and lowered by an electric cylinder. The structure of the second adjusting member 84 is the same as that of the first adjusting member 33. The width of the third cutters 85 on both sides can be adjusted to be greater than the width of the four second conveyor belts 81. The first pressure roller 82 and the second pressure roller 83 are both arranged along the width direction of the second conveyor belts 81 and are in contact with all the second conveyor belts 81. The second adjusting member 84 is located between the first pressure roller 82 and the second pressure roller 83. The active roller 63 and the passive roller 64 are connected to the feed end of the second conveyor belts 81. One end of the second conveyor belt 81 extends above the discharge end of the winding junction box 51.

[0053] After the filter paper is cut to a suitable width, it falls onto multiple second conveyor belts 81. The second adjusting member 84 first drives the third cutter 85 to insert into the corresponding cutting space and rotate. The multiple second conveyor belts 81 simultaneously drive the filter paper to the first pressure roller 82. The first pressure roller 82 presses the filter paper, and the third cutter 85 cuts the filter paper. After one end of the filter paper is cut, it passes through the second pressure roller 83. The first pressure roller 82 and the second pressure roller 83 cooperate to ensure that the filter paper can be accurately cut into several segments.

[0054] like Figure 6 and Figure 7The positioning and gluing assembly 9 includes a lifting seat 91, which is located above the roll-to-roll box 51. The lifting seat 91 is driven to rise and fall by an electric cylinder. The lifting seat 91 is equipped with a transverse adjustment component 92, which is connected to a pressure block 93. The lifting seat 91 is also equipped with a connecting plate 94, which is located below the lifting seat 91 and between the roll-to-roll fabric 55 and the second conveyor belt 81. The connecting plate 94 can connect with the roll-to-roll surface 551 of the roll-to-roll fabric 55. The transverse adjustment component 92 can drive the pressure block 93 to rise and fall and move the pressure block 93 along the length direction of the lifting seat 91. The lifting seat 91 is also equipped with a longitudinal adjustment component 95, which is equipped with a cold glue sprayer 96. The longitudinal adjustment component 95 is used to drive the cold glue sprayer 96 to move along the width and length directions of the lifting seat 91. The horizontal adjustment component 92 includes a lead screw, which is rotatably connected to the lifting seat 91. The lead screw is driven by a motor. The lead screw is threadedly connected to a moving block, which is slidably connected to the lifting seat 91. A cylinder is installed on the moving block, and the cylinder is connected to the pressure block 93. The longitudinal adjustment component 95 includes two lead screws, which are rotatably connected within the lifting base 91. The lead screw of the transverse adjustment component 92 is located between the two lead screws of the longitudinal adjustment component 95, and the position of the two lead screws of the longitudinal adjustment component 95 is lower than the position of the lead screw of the transverse adjustment component 92. The two lead screws of the longitudinal adjustment component 95 are driven by a motor, and both lead screws are threadedly connected to an adjustment block. The bottom of the adjustment block is also equipped with a motor and a lead screw. The lead screw of the adjustment block is arranged along the width direction of the lifting base 91, and the bottom surface of the adjustment block is fixed to the cold glue sprayer 96.

[0055] The filter paper is conveyed from the second conveyor belt 81 to the connecting plate 94. Then, the pressure block 93 presses the filter paper. The lifting seat 91 descends to connect the connecting plate 94 with the splicing surface 551 of the splicing cloth 55. The transverse adjustment component 92 drives the pressure block 93 to move. The pressure block 93 drags the filter paper to the designated position of the splicing surface 551. Then, the longitudinal adjustment component 95 drives the cold glue sprayer 96 to the overlap. The longitudinal adjustment component 95 then drives the cold glue sprayer 96 to move along the length of the filter paper to spray glue, realizing automatic positioning and glue spraying of the filter paper.

[0056] The bottom of the winding box 51 near the connecting plate 94 has a discharge port 512. The winding box 51 is equipped with a first sealing plate 591 and a second sealing plate 592. Both the first sealing plate 591 and the second sealing plate 592 are driven by electric cylinders. The first sealing plate 591 moves vertically up and down by electric cylinders, and the second sealing plate 592 moves horizontally left and right by electric cylinders. The first sealing plate 591 and the second sealing plate 592 together close the discharge port 512. The top surface of the second sealing plate 592 is a guide slope that slopes downward toward the first sealing plate 591. The first collection box 12 is located below the discharge port 512, the finished product slitting assembly 10 is directly opposite the discharge port 512, and the second collection box 13 is located below the finished product slitting assembly 10.

[0057] When the first sealing plate 591 is open and the second sealing plate 592 is closed, the discharge port 512 is connected to the finished product cutting assembly 10. When the first sealing plate 591 is closed and the second sealing plate 592 is open, the discharge port 512 is connected to the first collection box 12.

[0058] By adjusting the opening and closing states of the first sealing plate 591 and the second sealing plate 592, filter rods produced by two different manufacturing processes, namely cigarette gun forming and twisting forming, can be collected separately.

[0059] like Figure 6 and Figure 9 The finished product slitting assembly 10 includes a second receiving plate 101, which is connected to the discharge port 512. A second positioning groove 1011 is provided on the second receiving plate 101, which is arranged along the width direction of the second receiving plate 101. The inner diameter of the second receiving groove 421 is 2-5 mm larger than the inner diameter of the filter rod. A second support plate 102 is hinged to the end of the second receiving plate 101 away from the discharge port 512. The second support plate 102 swings up and down driven by a motor. Plate 102 is located above the feed end of the second collection box 13. The second support plate 102 has three third cutting grooves 1021 along its width direction. The experimental table 1 is provided with a third adjusting member 103. Three fourth cutters 104 are installed on the third adjusting member 103. The third adjusting member 103 is raised and lowered by an electric cylinder. The third adjusting member 103 has the same structure as the second adjusting member 84 and the first adjusting member 33. The width between the fourth cutters 104 on both sides can be adjusted to be greater than the width of the second receiving plate 101.

[0060] The second receiving plate 101 is provided with a second reciprocating member 105 and a second clamping member 106. The second clamping member 106 is used to hold the two ends of the filter rod that falls into the second positioning groove 1011. The second reciprocating member 105 is used to simultaneously transport the second clamping member 106 and the filter rod to the second support plate 102. The third adjusting member 103 is used to adjust the plurality of third cutters 85 to a suitable spacing. The second reciprocating member 105 has the same structure as the first reciprocating member 35. The second reciprocating member 105 is arranged on both sides of the second receiving plate 101. The second clamping member 106 has the same structure as the first clamping member 36.

[0061] The filter rod formed from the cigarette holder is transported out from the cigarette box 51 and falls onto the second positioning groove 1011 of the second receiving plate 101. Then, the second clamping member 106 clamps the filter rod, and the second reciprocating member 105 drives the second clamping member 106 and the filter rod to move onto the second support plate 102. The third adjusting member 103 controls the fourth cutter 104 to descend and cut the filter rod, forming multiple multi-element composite filter rods.

[0062] The implementation principle of this application embodiment is as follows: the first material collection component 2 feeds the filter rod to the filter rod cutting component 3 for fixed-length cutting, and then stores it in the second material collection component 4. Each second material collection component 4 stores different types of filter rods. According to the filter rod types and arrangement designed in the multi-element filter rod, multiple second material collection components 4 discharge the filter rods in sequence according to the combination order of the filter rods, and are conveyed to the winding component 5 by the first conveyor belt 11. Under the transmission action of the first transmission belt, after multiple filter rods reach the winding component 5, they are spliced ​​end to end for combination. Then, the winding component 5 adjusts the position of all filter rods to prepare for winding with the filter paper. While the filter rod is being cut to a fixed length, the unwinding assembly 6 simultaneously unwinds the filter paper. The filter paper is then transported to the cutting assembly 7 for cutting. Depending on the selected process, the filter paper undergoes different operating steps. If the cigarette gun forming process is selected, the filter paper is only conveyed by the filter paper slitting component 8 without being slitted. The filter paper slitting component 8 transports the filter paper to the positioning and gluing component 9. The positioning and gluing component 9 transfers the filter paper to the designated position of the winding component 5 for gluing. Then the winding component 5 can wind the filter rod and the filter paper together. At this time, multiple multi-element filter rods are wound inside one sheet of filter paper. The wound paper is conveyed to the finished product slitting component 10 to be cut into multiple finished multi-element filter rods and transported to the second collection box 13 for collection. If the twisting and forming process is selected, the filter paper is cut into several filter papers of the same length as a single multi-element combination filter rod by the filter paper cutting component 8. Then, the positioning and gluing component 9 transfers the filter paper to the designated position of the winding component 5 for gluing. Then, the winding component 5 can wind the filter rod and filter paper together and transport them directly to the first collection box 12 for collection. Therefore, this equipment can produce samples of binary, ternary, quaternary, and even multi-element filter rods. It can also select the sample manufacturing process according to the actual production process, making it highly adaptable and efficient in producing samples.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
