[0051] The terms "upper", "lower", "inner", "outer", etc. do not constitute absolute spatial relationship limitations, but are only concepts of relative positions, which can be understood by those skilled in the art.

[0052] See also Figure 1 The utility model takes the processing of empty cigarette paper tubes in the shape of a truncated cone as an example. The first forming paper is trapezoidal, and the second forming paper is similar to a fan shape.

[0053] See also Figure 2-4 The cigarette empty paper tube forming equipment comprises a frame 200, on which are arranged a first forming paper feeding and cutting device 1000, a first forming paper gluing device, a first forming paper feeding device 2000, a second forming paper automatic paging feeding device 3000, a second forming paper feeding device 4000, a second forming paper feeding mechanism 5000 and a roll paper forming device 6000.

[0054] See also Figure 5-10, The first shaping paper feeding and cutting device 1000 is used to cut the first shaping paper feeding paper tape into a preset shape, and comprises a first shaping paper conveying device 1400 and a cutting knife used to cut the first shaping paper feeding paper tape 100 .

[0055] See also Figure 2 and Figure 5 The first molded paper conveying device 1400 includes a paper tape unwinding reel 1401, a paper feed guide roller group 1402 consisting of two guide rollers, a conveying plate 1420 and a pressing block 1430. A paper clamping surface is formed between the two guide rollers.

[0056] See also Figure 5-9The first molding paper conveying device 1400 is provided with a feeding paper tape limiting structure 1410 to prevent the feeding paper tape from running off. The conveying plate 1420 is arranged at the front of the first molding paper conveying device 1400 to facilitate the smooth feeding of the feeding paper tape. The pressing block 1430 is arranged above the front end of the conveying plate 1420, and a paper feeding gap is arranged between the pressing block 1430 and the conveying plate 1420, so that the first molding paper feeding paper tape 100 passes through the pressing block 1430 and the conveying plate 1420. There is a certain friction between the first molding paper feeding paper tape 100 and the pressing block 1430 and the conveying plate 1420. The first molding paper feeding paper tape 100 passes through the paper tape unwinding reel 1401, the paper clamping surface of the paper feeding guide roller group 1402, the conveying plate 1420, and the paper feeding gap in sequence. A traction clamp 1500 that can move forward and backward is arranged in front of the first shaping paper conveying device 1400 to drive the first shaping paper feeding paper belt 100 to move. The traction clamp 1500 is installed on a linear guide device 1510 superior .

[0057] The cutting knife includes a first cutting knife 1200 arranged at the front end of the first shaping paper conveying device, the first cutting knife 1200 is installed on the frame 200, and the first cutting knife 1200 is used to horizontally cut the continuous first shaping paper feeding paper belt 100 conveyed by the first shaping paper conveying device 1400. The first cutting knife can adopt a conventional scissors structure. When the first shaping paper is rectangular, it is only necessary to control the cutting direction of the first cutting knife 1200 to be perpendicular to the feeding direction of the first shaping paper conveying device 1400 and the distance between the two cuttings of the first cutting knife 1200.

[0058] In this embodiment, since the first shaping paper is a trapezoidal shape with a small top and a large bottom, in order to simplify the cutting structure, this embodiment uses two cutting knives to cooperate with the first shaping paper conveying device to achieve the cutting of the trapezoidal paper piece. A second cutting knives 1300 is also installed on the frame 200. The second cutting knives 1300 are arranged on one side of the first shaping paper conveying device 1400.

[0059] See also Figure 10, The cutting position of the first cutting knife 1200 is not perpendicular to the feeding direction of the first molding paper conveying device 1400, but is arranged to intersect. The cutting direction of the first cutting knife 1200 and the feeding direction of the first molding paper conveying device 1400 form an angle α less than 90 degrees, and the angle α is preferably between 45 degrees and 90 degrees. Without considering the second cutting knife 1300, as the first molding paper conveying device 1400 conveys a continuous feed paper tape, the first cutting knife 1200 can cut the first molding paper feed paper tape 100 into two parallel bottom edges through two cuttings.

[0060] The second cutting knife 1300 is arranged on one side of the long side of the first shaping paper feeding paper strip cut by the first cutting knife 1200 (such as Figure 10 The second cutting knife 1300 is used to cut the first shaping paper feeding tape 100 obliquely. The cutting direction of the second cutting knife 1300 is as follows: along the feeding direction, the cutting line gradually deviates from the intersection point of the first shaping paper feeding tape 100 to the other side of the first shaping paper feeding tape 100. The oblique edge obtained after the first shaping paper feeding tape 100 is cut by the second cutting knife 1300 and the other side of the first shaping paper feeding tape 100 form the two sides of the trapezoidal paper piece. As the first shaping paper feeding tape 100 moves, after the second cutting by the first cutting knife 1200, the short bottom side of the obtained trapezoidal paper piece is in front and the long bottom side is in the back, as shown in FIG. Figure 10 As shown in the right part, the "front" and "back" here are based on the feeding direction. The direction of the arrow is "front", and the opposite direction is "back".

[0061] See also Figure 10, The cutting direction of the second cutting knife 1300 forms an angle β with the cutting direction of the first cutting knife 1200, and the angle β is equal to the angle α. The trapezoidal paper piece obtained by adopting this structure has two equal bottom angles and two equal waists. The trapezoidal paper piece has a symmetrical structure, which is convenient for paper roll forming, and the qualified rate of the formed product is high.

[0062] The second cutting knife 1300 includes a sliding cutting knife body 1310, one end of which is rotatably connected via a shaft 1311, and a telescopic push rod 1320 is connected to the sliding cutting knife body 1310. The widths of the conveying plate 1420 and the pressing block 1430 are both less than two-thirds of the width of the first molding paper feeding tape 100, and the side of the first molding paper feeding tape 100 close to the second cutting knife is suspended. The sliding cutting knife body 1310 cooperates with the side of the conveying plate 1420 for cutting.

[0063] See also Figure 5 , Figure 7 , Figure 8 , Fig. 9 The first molding paper glue dispensing device 1600 is used to glue one side of the first molding paper feed tape 100, and the discharge port of the first molding paper glue dispensing device is located above the edge of the first molding paper feed tape 100. In this embodiment, the first molding paper feed tape 100 uses a paper tape with a self-adhesive layer on the edge, and only a small amount of water is needed to make it sticky. The first molding paper glue dispensing device 1600 is filled with water, and the water discharge is controlled by a control valve. The discharge port of the first molding paper glue dispensing device 1600 is close to the first molding paper feed tape 100. As the first molding paper feed tape 100 moves forward, during this process, the control valve of the first molding paper glue dispensing device 1600 opens, and water is left on the glue layer of the first molding paper feed tape 100 in a linear shape.

[0064] Of course, if the first molding paper feed tape 100 is a conventional paper tape, then the first molding paper dispensing device 1600 is filled with glue, and the dispensing valve (control valve) is used to control the glue discharge, and the dispensing port of the dispensing valve is close to the first molding paper feed tape 100.

[0065] The working process of the first shaping paper feeding and cutting device 1000 is as follows:

[0066] When the first molding paper feed tape 100 moves forward driven by the traction clamp 1500, during this process, the first cutting knife 1200 is in an open state, which facilitates the traction clamp 1500 to move forward and backward. After the first molding paper feed tape 100 moves to the preset position, the first cutting knife 1200 performs the first cutting; then the telescopic push rod 1320 of the second cutting knife 1300 contracts, driving the sliding cutter body 1310 to move downward, cutting the suspended first molding paper feed tape on the conveying plate 1420 to obtain a bevel; then, the traction clamp 1500 moves backward to the front end of the first molding paper feed tape 100, clamps the first molding paper feed tape 100, and drives the first molding paper feed tape 100 to move forward. During this process, the dispensing valve of the first molding paper dispensing device 1600 is opened, and the edge of the first molding paper feed tape 100 is continuously glued. After the first shaping paper feeding tape 100 moves to the preset feeding station, the first cutting knife 1200 performs a second cutting, and the pre-designed trapezoidal paper piece can be obtained. This action is repeated.

[0067] See also Fig.11 The first shaping paper feeding device 2000 is located at the front end of the first shaping paper feeding and cutting device 1000, and is used to feed the cut first shaping paper to the roll paper shaping device 6000. It mainly includes a first lifting device 2100 and a feeding platform 2200 installed on the first lifting device. The first lifting device 2100 adopts a screw lifting device, which has a strong bearing capacity and is easy to operate. The nut seat 2110 is mounted on the screw rod 2120, and the screw rod 2120 is connected to the driving motor. The nut seat 2110 can move up and down along the screw rod 2120. The nut seat 2110 and the feeding platform 2200 are fixedly connected by bolts 2111, and the feeding platform 2200 is lifted up and down along with the nut seat 2110.

[0068] See also Fig.12The feeding platform 2200 is provided with left and right movable blocks (2210, 2220) that can be opened to the middle in an inverted "eight" shape. The bottom of the left and right movable blocks (2210, 2220) are respectively provided with connecting arms 2230, and the connecting arms 2230 are connected to the feeding platform through shafts 2231, and the connecting arms 2230 can swing around the shafts 2231. A torsion spring is installed on the shaft 2231, and the torsion spring on the left side drives the connecting arm on the left side to swing to the left, and the torsion spring on the right side drives the connecting nose on the right side to swing to the right, so that the left and right movable blocks (2210, 2220) are in an outwardly opened state in a natural state. The feeding platform 2200 is provided with movable block limiters 2232 to limit the opening range of the two movable blocks. Of course, other methods may also be used to drive the left and right movable blocks (2210, 2220) to open outward, such as common elastic structures such as tension springs and springs that apply outward force to the movable blocks or connecting arms.

[0069] An elastic material layer for placing the first shaping paper is fixedly connected between the left and right movable blocks (2210, 2220); since the first shaping paper is relatively thin, the elastic material layer is an elastic breathable material layer 2240; the elastic breathable material layer 2240 can be made of cloth, bamboo fiber and other materials. A first adsorbent for absorbing the first shaping paper through the elastic breathable material layer is provided between the left and right movable blocks and below the elastic breathable material layer 2240. In this embodiment, the first adsorbent is a hollow adsorbent 2250. The left side of the elastic breathable material layer 2240 is fixed to the left movable block 2210, and the right side of the elastic breathable material layer 2240 is fixed to the right movable block 2220. Since the left and right movable blocks (2210, 2220) are in an outwardly open state in a natural state, the elastic breathable material layer 2240 connected between the left and right movable blocks (2210, 2220) is in a taut state driven by the left and right movable blocks, and the breathability is enhanced.

[0070] The hollow adsorbent 2250 is arranged on the feeding platform 2200 through a spring 2251, the lower end of the spring is connected to the feeding platform 2200, and the upper end is connected to the hollow adsorbent 2250. The hollow adsorbent 2250 can be extended and retracted in the up and down directions through the spring 2251. In the natural state, the upper adsorption port of the hollow adsorbent supports the elastic breathable material layer 2240.

[0071] After the first shaping paper is cut for the second time by the first cutting knife 1200, the first shaping paper just falls on the elastic breathable material layer 2240, and the hollow adsorbent 2250 adsorbs the first shaping paper. The first lifting device 2100 drives the feeding platform 2200 to rise to the position of the paper roll forming mandrel. The first shaping paper and the elastic breathable material layer 2240 are supported by the paper roll forming mandrel. As the feeding platform 2200 continues to rise, the hollow adsorbent 2250 overcomes the spring force and moves downward under the pressure of the paper roll forming mandrel. The middle of the first shaping paper and the elastic breathable material layer 2240 is concave downward. The left and right movable blocks (2210, 2220) overcome the spring force and close to the middle under the drive of the elastic breathable material layer 2240, bend the first shaping paper and wrap it on the outer surface of the paper roll forming mandrel. Then the paper roll forming mandrel starts to roll paper. After the material processing is completed, the feeding platform descends, and the hollow adsorbent 2250 moves upward and resets under the action of the spring 2251. The left and right movable blocks are reset under the elastic force of the torsion spring, and the elastic breathable material layer is tightened, waiting for the next material to be loaded.

[0072] See also Figure 2 and 4 A second shaping paper feeding device 4000 is also provided on the frame 200, which mainly includes a conveyor belt 4200 and a second shaping paper gluing device. Since the second shaping paper is a cardboard sheet, it is formed by punching out the stacked raw material paper sheets together. The punched cardboard sheets remain in a stacked state and need to be separated into sheets for feeding one by one. Therefore, a second shaping paper automatic paging feeding device 3000 is provided on the second shaping paper feeding device 4000. The second shaping paper automatic paging feeding device 3000 is used to separate the stacked cardboard sheets and feed them individually.

[0073] See also Figure 13-Figure 16 The second shaping paper automatic paging feeding device 3000 includes a frame (equivalent to a silo) to prevent the stacked cardboard sheets 400 on the conveyor belt from tilting, and the frame includes at least a limiter distributed on the left and right sides of the stacked cardboard sheets. In this embodiment, the limiter includes a plurality of vertical limiter rods 3120. Of course, a conventional limiter structure such as a limiter plate can also be used. The vertical limiter rod 3120 is fixed by a connecting member 3130.

[0074] The baffle 3200 is disposed above the conveyor belt 4200 and blocks the front end of the stacked cardboard sheets 400 to prevent the stacked cardboard sheets 400 from moving as a whole with the conveyor belt 4200, and a discharge gap 3210 that only allows a single cardboard sheet to pass through is provided between the baffle 3200 and the conveyor belt 4200.

[0075] The baffle 3200 is connected to a height fine-tuning mechanism. The height fine-tuning mechanism includes a connecting block 3220 connected to the baffle, the connecting block is sleeved on the vertical shaft 3230 of the frame, the lower end of the connecting block 3220 is connected to a spring 3240, and the upper end is connected to a screw micrometer 3250. The screw micrometer 3250 is a high-precision distance measurement and adjustment device, which is an existing structure. The height of the connecting block 3220 is fine-tuned by rotating the screw micrometer 3250, thereby adjusting the height of the baffle 3200, thereby adjusting the discharge gap 3210. The height of the discharge gap 3210 is preferably 1.2-1.7 times the thickness of the cardboard. In this embodiment, the height of the discharge gap 3210 is 1.5 times the thickness of the cardboard.

[0076] The clamping device 3300 presses down one end of the stacked cardboard 400 close to the discharge gap. Its functions are: the cardboards are stacked together with the center of gravity in the middle. The clamping device 3300 can prevent the end of the cardboard close to the discharge gap from tilting, so that the end of the stacked cardboard close to the discharge gap is close to the conveyor belt 4200, so that the cardboard can smoothly come out of the discharge gap 3210; the second is to increase the friction between the bottom cardboard and the conveyor belt 4200, and drive the cardboard to move with the conveyor belt 4200 through the friction.

[0077] The clamping device includes a counterweight 3310 and a pressure arm 3320. The counterweight 3310 is mounted on one of the vertical limit shafts 3120. One end of the pressure arm 3320 is fixedly connected to the counterweight 3310 with bolts, and the other end of the pressure arm 3320 is correspondingly arranged above one end of the stacked cardboard sheets near the discharge gap. The pressure arm provides downward pressure under the weight of the counterweight.

[0078] A fixed pad 3150 is provided at one end of the cardboard of the conveyor belt away from the discharge gap. The fixed pad 3150 is fixed on the frame. One end of the stacked cardboard 400 away from the discharge gap 3210 is placed on the fixed pad 3150, so that the center of gravity of the stacked cardboard is moved forward, and further the end of the cardboard close to the discharge gap is closely attached to the conveyor belt, which is convenient for discharge.

[0079] In addition, the surface of the conveyor belt 4200 is a non-slip surface structure. Through the cooperation of the clamping device, the friction between the bottom cardboard and the conveyor belt is greater than the friction between the bottom cardboard and the second to last cardboard.

[0080] When the conveyor belt 4200 is working, the friction between the conveyor belt 4200 and the cardboard 400 drives the cardboard to move with the conveyor belt; by setting a discharge gap 3210 between the baffle and the conveyor belt that only allows a single cardboard to pass through, automatic paging and loading of stacked cardboard sheets can be achieved.

[0081] See also Figure 17-Figure 19A second lifting device 4110 is provided on one side of the conveyor belt 4200 of the second shaping paper feeding device 4000, and the second lifting device 4110 is fixed on the frame. The second lifting device 4110 includes a fixed seat 4112 and a lifting platform 4111, and the lifting platform 4111 can move up and down (vertically lift) relative to the fixed seat 4112. A second adsorption component is fixedly connected to the lifting platform 4111. In this embodiment, the second adsorption component adopts a hollow suction cup 4300, and the hollow suction cup 4300 is located directly above the conveyor belt 4200. The second lifting device 4110 is lifted vertically to suck up the cardboard 400 on the conveyor belt 4200 and rise for feeding.

[0082] The second molding paper dispensing device includes a dispensing valve 4400, the feed port of the dispensing valve 4400 is connected to the glue cylinder 4410, the dispensing valve 4400 is vertically arranged, and the lower end thereof is connected to a glue outlet pipe 4420, and the glue outlet 4430 at the lower end of the glue outlet pipe 4420 is located directly above the conveyor belt 4200, and the position of the glue outlet 4430 corresponds to the edge position of the cardboard loading station on the conveyor belt directly below.

[0083] After the paginated cardboard 400 moves from the conveyor belt 4200 to the preset position, the second lifting device 4110 starts to work, driving the hollow suction cup 4300 to move downward. When the hollow suction cup 4300 is close to the upper surface of the cardboard 400, the hollow suction cup 4300 sucks the cardboard 400 through the operation of the hollow pumping device. Then the lifting platform 4111 of the second lifting device 4110 rises, driving the hollow suction cup 4300 and the cardboard 400 to rise until the upper surface of the cardboard 400 adsorbed by the hollow suction cup 4300 is 2-5 mm from the glue outlet 4430 of the dispensing valve. The lower end of the water drop-shaped glue coming out of the glue outlet 4430 of the dispensing valve 4400 is attached to the upper surface of the cardboard 400 to achieve dispensing.

[0084] See again Figure 2 and Figure 4 The second shaping paper feeding mechanism 5000 is used to feed the second shaping paper to the roll shaping device; the second shaping paper feeding mechanism 5000 includes a movable clamping jaw 5100 for clamping the second shaping paper, and the movable clamping jaw 5100 is arranged on a linear sliding platform 5200. The linear sliding platform 5200 includes a linear guide mechanism 5210 that moves left and right, and a telescopic rod mechanism 5220 that can move forward and backward is arranged on a slide 5211 of the linear guide mechanism. The movable clamping jaw 5100 is fixed on the telescopic rod mechanism 5220, and moves forward and backward as the telescopic rod mechanism 5220 is extended and retracted, and moves left and right as the slide 5211 slides.

[0085] When the cardboard 400 is glued, the movable clamping jaw 5100 moves forward under the drive of the telescopic rod mechanism 5220, clamps the cardboard 400, and then moves backward to reset. Then, the movable clamping jaw 5100 moves rightward under the drive of the slide 5211 to the front of the roll paper forming mandrel, and the telescopic rod mechanism 5220 drives the movable clamping jaw 5100 forward again to load the cardboard 400 into the second forming paper receiving groove of the roll paper forming mandrel. The telescopic rod mechanism 5220 shrinks and resets, and the slide 5211 moves leftward to reset.

[0086] See also Figure 2 , 3 4. A roll paper forming device 6000 is used to roll the first forming paper and the second forming paper. The roll paper forming device 6000 is located above the first forming paper feeding device 2000.

[0087] See also Fig. 20 The roll forming device 6000 mainly includes a roll forming mandrel 6400, which is connected to a reducer 6300 and driven by the reducer to rotate around its own axis. The roll forming mandrel 6400 is located on the upward movement path of the elastic breathable material layer 2240.

[0088] See also Fig.21 In this embodiment, the paper roll forming mandrel 6400 adopts a segmented structure, including a mandrel front section 6100 and a mandrel rear section 6200 made of metal. The segmented structure is convenient for mandrel processing and reduces processing costs.

[0089] Since the cigarette paper tube is in the shape of a truncated cone, the first shaping paper is in the shape of a trapezoid, and the second shaping paper is similar to a fan. Therefore, the front section 6100 of the mandrel includes a second paper shaping section 6110 and a first paper shaping section 6120. The length of the second paper shaping section is 2-5 cm, and the length of the first paper shaping section is 8-15 cm. The second paper shaping section 6110 and the first paper shaping section 6120 are both truncated cone structures with one end large and the other end small. The tail end of the second paper shaping section 6110 is welded to the front end of the first paper shaping section 6120; the interior of the first paper shaping section is a hollow structure 6121, and the surface of the first paper shaping section is provided with air holes 6122 connected to the hollow structure 6121. The air holes 6122 can be provided in multiple groups, and the air holes 6122 are evenly distributed along the circumferential direction of the surface of the first paper shaping section, and the air holes 6122 are arranged at equal intervals along the length direction of the first paper shaping section. By providing the hollow structure and the air holes, when the paper roll is formed, the first forming paper (thin paper sheet) is first adsorbed on the surface of the first paper roll forming section, and then the paper roll forming core shaft 6400 is driven by the reducer 6300 to rotate, so that the first forming paper (thin paper sheet) paper roll can be completed, which effectively prevents the paper sheet from moving and reduces the defective product rate.

[0090] The front end surface of the second paper roll forming section 6110 is provided with a second paper forming receiving groove 6111. The second paper forming (cardboard) is loaded into the second paper forming receiving groove 6111, and the paper roll forming core shaft 6400 is driven by a motor to rotate, thereby completing the paper rolling of the second paper forming.

[0091] The rear section 6200 of the mandrel is used to connect to an external driving mechanism. The interior of the rear section of the mandrel is also a hollow structure 6210, and is connected to the hollow structure 6121 of the first paper roll forming section. The hollow structure 6210 of the rear section of the mandrel is connected to an external hollowing device, so that the air holes 6122 of the first paper roll forming section 6120 can absorb thin paper sheets. The surface of the rear section of the mandrel is provided with a keyway for connecting to an external driving mechanism.

[0092] The front section 6100 of the mandrel and the rear section 6200 of the mandrel are positioned by positioning pins and positioning holes and connected by bolts.

[0093] The production of different product specifications can be achieved by replacing the mandrel front section 6100.

[0094] The first forming paper is driven to the roll forming mandrel 6400 by the feeding platform 2200, and the left and right movable blocks (2210, 2220) are closed toward the middle to bend the first forming paper and press it on the outer surface of the roll forming mandrel 6400. Then the roll forming mandrel 6400 starts to roll the first forming paper.

[0095] The second shaping paper is sent to the second shaping paper receiving groove 6111 of the paper roll shaping core shaft 6400. The left and right movable blocks (2210, 2220) can also be closed in the middle to bend the second shaping paper and press it on the outer surface of the paper roll shaping core shaft 6400. However, in this embodiment, in order to avoid interference between the actions of various mechanisms and to increase the paper roll efficiency, see Fig. 20 The roll forming device 6000 includes a pressing wheel 6500 for pressing the second forming paper. The side of the pressing wheel 6500 is provided with a hard plate metal, which further bends the second forming paper (hard paper sheet 400) to facilitate the forming of the roll paper. The pressing wheel 6500 is connected to a telescopic device, and the telescopic device drives the pressing wheel to be close to or away from the roll forming core shaft 6400. The telescopic device is connected to the frame through a bracket.

[0096] The processing sequence is: firstly roll the second forming paper (cardboard 400) into shape, then feed the first forming paper to the bottom of the roll forming mandrel 6400 through the first forming paper feeding device 2000, the front end of the first forming paper covers the rear end of the second forming paper, and the first forming paper is rolled into shape through the roll forming mandrel 6400. The first forming paper and the second forming paper are bonded together by the overflow of glue.

[0097] In addition, a telescopic clamp 7000 for clamping the formed piece is provided in front of the roll paper forming core shaft 6400, and the material is unloaded through the telescopic clamp 7000. A material unloading chute 7100 is provided below the telescopic clamp 7000.
