DETAILED DESCRIPTION

[0048] The specific implementation of the utility model will be described below with reference to the accompanying drawings of the specification.

[0049] As a specific embodiment, the continuous roll forming device of the embodiment of the utility model includes a sheet loading device 1, a gluing device 2, a roll forming device 3, a roll discharge structure 5 and an installation carrier 9 for installation; in other words, the installation carrier 9 is used to install the sheet loading device 1, the gluing device 2, the roll forming device 3 and the roll discharge structure 5 so that the sheet loading device 1, the gluing device 2, the roll forming device 3 and the roll discharge structure 5 are an integral device; of course, it is easy to understand that the sheet loading device 1, the gluing device 2, the roll forming device 3 and the roll discharge structure 5 can also be installed on multiple installation carriers 9 to form separate devices.

[0050] The sheet loading device 1 comprises a sheet loading power wheel 11, a sheet forming cutter 12, a buffer belt 13 and a sheet loading rotating wheel 19, which are arranged in sequence. The sheet forming cutter 12 has a reciprocating power; the buffer belt 13 has a planar portion and the planar portion is tangent to the sheet loading power wheel 11. Usually, a sheet loading driven wheel (not shown in the drawing) is arranged above the sheet loading power wheel 11 and cooperates with the sheet loading power wheel 11.

[0051] The planar portion of the buffer belt 13 has negative pressure and horizontal conveying power. For example, the buffer belt 13 is a flexible annular belt and is driven by the buffer belt power wheel 139 to have conveying power. A buffer support 131 is provided in the buffer belt 13. The buffer support 131 is provided with a negative pressure cavity 132 connected to negative pressure. The top surface of the buffer support 131 fits the planar portion of the buffer belt 13. The top surface of the buffer support 131 and the entire buffer belt 13 are provided with through holes that penetrate to the negative pressure cavity 132. The planar portion of the buffer belt 13 always has negative pressure, which can ensure that the belt-like object 81 or sheet-like object 82 thereon is flat.

[0052] The upper film rotating wheel 19 has a rotational power and is provided with an upper film adsorption head 191, and the upper film adsorption head 191 is connected to a negative pressure. For example, the upper film rotating wheel 19 is driven by the upper film synchronous wheel 721 described later and has a rotational power.

[0053] The upper sheet adsorption head 191 can directly or indirectly adsorb the sheet 82 on the planar portion of the buffer belt 13. For example, when the vertical plane passing through the axis of the upper sheet rotating wheel 19 passes through the planar portion of the buffer belt 13, the upper sheet adsorption head 191 on the upper sheet rotating wheel 19 can directly adsorb the sheet 82 on the planar portion of the buffer belt 13 when it rotates to the lowest position. The embodiment in which the sheet 82 on the planar portion of the buffer belt 13 is adsorbed by the upper sheet adsorption head 191 after being transported by the upper sheet output belt 14, the transition belt 15, etc. described later, is an embodiment in which the upper sheet adsorption head 191 indirectly adsorbs the sheet 82 on the planar portion of the buffer belt 13.

[0054] The working principle of the upper sheet device 1 is that the upper sheet driven wheel and the upper sheet power wheel 11 clamp the belt 81, and the upper sheet power wheel 11 rotates to move the belt 81 between the upper sheet driven wheel and the upper sheet power wheel 11, so that one end of the belt 81 extends to the plane of the buffer belt 13 for partial loading. At this time, one end of the belt 81 remains in a plane, and the sheet forming cutter 12 reciprocates to cut off one end of the belt 81 to form a sheet 82.

[0055] After that, the upper sheet adsorption head 191 directly or indirectly adsorbs the sheet 82 on the plane of the buffer belt 13. During the rotation of the upper sheet rotating wheel 19, the glue coating device 2 applies glue to the sheet 82 adsorbed by the upper sheet adsorption head 191 to form a glue-coated sheet 83. The glue coating device 2 is a conventional device for applying glue to the sheet 82 in the prior art.

[0056] The glue-coated sheet 83 adsorbed by the upper sheet adsorption head 191 moves to the highest point of the upper sheet rotating wheel 19 along with the upper sheet rotating wheel 19. At this time, the glue-coated sheet 83 is roughly horizontal and is clamped by the rotating clamp 341 and the opening and closing clamp 351 described later.

[0057] It can be seen from the above that the sheet loading device 1 can continuously cut the strip 81 into sheets 82 and load the glue-coated sheet 83 onto the sheets.

[0058] As one of the specific embodiments, the sheet loading device 1 also includes a transition belt 15 with a conveying power, for example, driven by a transition power wheel 159 to have a conveying power; the transition belt 15 includes a transition upper belt 151 and a transition lower belt 152; the transition upper belt 151 and the transition lower belt 152 both have a planar portion, the planar portion of the transition upper belt 151 and the planar portion of the transition lower belt 152 fit each other and are in contact with the planar portion of the buffer belt 13 in the conveying direction (such as Figure 6 In the left and right directions shown in FIG. 1 , there are overlapping parts and they are located in the same plane. When viewed from above, the upper transition belt 151 and the lower transition belt 152 are completely staggered with the buffer belt 13 in the width direction. For example, Figure 6 As shown, there are two transition upper belts 151 and transition lower belts 152, which are respectively located on both sides of the buffer belt 13. The buffer belt 13 conveys the sheet 82 thereon to the aforementioned overlapping portion, and a portion of the sheet 82 is clamped by the planar portion of the transition upper belt 151 and the planar portion of the transition lower belt 152 and continues to be conveyed until the sheet 82 is separated from the buffer belt 13. At this time, the sheet 82 is not adsorbed by the negative pressure of the buffer belt 13 but is more easily adsorbed by the upper sheet adsorption head 191, which can improve the reliability of adsorption by the upper sheet adsorption head 191. For example, the upper sheet adsorption head 191 adsorbs a portion of the belt 81 between the two transition upper belts 151, thereby indirectly adsorbing the sheet 82 on the planar portion of the buffer belt 13.

[0059] As one of the specific embodiments, the sheet loading device 1 further includes a sheet loading support 141 and a sheet loading belt 14 with a conveying power. The sheet loading belt 14 has a planar portion. The planar portion of the sheet loading belt 14 and the planar portion of the transition upper belt 151 are located on the same plane and overlap in the conveying direction. The sheet loading support 141 and the planar portion of the sheet loading belt 14 are in contact with or close to each other. The vertical plane passing through the rotation axis of the sheet rotating wheel 19 passes through the planar portion of the sheet loading belt 14. After a portion of the sheet 82 is clamped by the planar portion of the transition upper belt 151 and the planar portion of the transition lower belt 152 and is conveyed to the sheet loading belt 14, the sheet loading belt 14 conveys the sheet 82 until it is adsorbed by the sheet adsorption head 191. In the process of the sheet adsorption head 191 adsorbing the sheet 82, the middle portion of the sheet 82 will not be concave but will be in a planar state as a whole, so as to ensure that the sheet 82 is adsorbed by the sheet adsorption head 191.

[0060] As one of the specific implementations, the ratio of the conveying line speed of the upper sheet output belt 14 to the conveying line speed of the transition belt 15 is a constant value greater than one. For example, assuming that the conveying line speed of the upper sheet output belt 14 is two meters per second and the conveying line speed of the transition belt 15 is one meter per second, the ratio of the two is two. The sheet 82 is transported from the transition belt 15 to the upper sheet output belt 14 and separated at equal intervals, so as to be adsorbed by the upper sheet adsorption head 191.

[0061] As one of the specific implementations, the sheet loading device 1 further includes a sheet loading pressure rod 142, which has a tendency to approach the sheet loading support 141. For example, one end of the sheet loading pressure rod 142 is hinged to the mounting carrier 9, and the other end of the sheet loading pressure rod 142 has a tendency to approach the sheet loading support 141 by its own weight. This ensures that the spacing between the sheet objects 82 on the sheet loading belt 14 is not easily changed, so that the sheet objects 82 can be easily adsorbed by the sheet adsorption head 191.

[0062] As one of the specific embodiments, the sheet loading device 1 further includes a cutter fixed die 121, a sheet forming swing arm 123, and a sheet forming power wheel 122 with a rotational power, the sheet forming cutter 12 is linearly slidably connected to the cutter fixed die 121; one end of the sheet forming swing arm 123 is eccentrically hinged to the sheet forming power wheel 122, and the other end is hinged to the sheet forming cutter 12, and the sheet forming cutter 12 is fitted to the cutter fixed die 121. The sheet forming power wheel 122 rotates so that the sheet forming cutter 12 reciprocates up and down to cut the strip 81 to form a sheet 82.

[0063] As one of the specific implementations, the film loading device 1 also includes a negative pressure plate 16, a label tracking sensor 161, an unwinding wheel 18, and an unwinding motor 189 that drives the unwinding wheel 18 to rotate. The label tracking sensor 161 is electrically connected to the unwinding motor 189, and the label tracking sensor 161 is facing the negative pressure plate 16. The negative pressure plate 16 can achieve negative pressure in the same way as the cache support 131, which will not be repeated here. The belt roll 8 is fixed on the unwinding wheel 18 and leads out the belt 81. The belt 81 passes through the negative pressure plate 16 and is adsorbed on the negative pressure plate 16 to form a plane. The label tracking sensor 161 is a conventional device in the prior art for identifying labels on the sheet 82. The unwinding motor 189 rotates according to the identification signal of the label tracking sensor 161 on the label on the sheet 82, and can automatically control the speed of releasing the sheet 82 as needed. The loading device 1 also includes a deflection correction sensor 162 and a deflection correction motor (not shown in the drawings) capable of causing the unwinding wheel 18 to swing. The deflection correction sensor 162 is a conventional sensor in the prior art for identifying the positions of both sides of the belt 81. The deflection correction sensor 162 is electrically connected to the deflection correction motor. The deflection correction motor causes the unwinding wheel 18 to swing according to the signal of the deflection correction sensor 162 to achieve deflection correction.

[0064] As one of the specific embodiments, the film loading device 1 also includes a tension adjustment structure 17; the tension adjustment structure 17 includes a movable tension wheel frame 173, a plurality of fixed tension wheels 171, and a plurality of movable tension wheels 172 arranged on the movable tension wheel frame 173; it is easy to understand that the position of the fixed tension wheel 171 is fixed relative to the mounting carrier 9, and the movable tension wheel frame 173 can slide linearly relative to the fixed tension wheel 171, for example, by a linear guide rail 174 to achieve linear sliding relative to the fixed tension wheel 171. The belt 81 bypasses the fixed tension wheel 171 and the movable tension wheel 172 in turn to achieve tensioning of the belt 81, which can ensure that the belt 81 is flat. The friction force of the linear guide rail 174 and the weight of the movable tension wheel frame 173 are adjustable to achieve adjustable tensioning force on the belt 81.

[0065] The roll forming device 3 includes a turntable 31 , a clamping assembly 34 and a pressing assembly 36 .

[0066] The turntable 31 has a rotational power. For example, the turntable 31 is fixedly provided with a turntable power shaft 319, and the turntable power shaft 319 is rotated by conventional driving means such as a motor; of course, the rotational drive can be realized by the synchronous driving structure 7 described later.

[0067] The clamping piece assembly 34 includes a rotating jaw 341 and an opening and closing jaw 351 that can rotate relative to the rotating jaw 341; the rotating jaw 341 and the opening and closing jaw 351 together form a cylindrical or truncated cone shape. It is easy to understand that the shape formed by the rotating jaw 341 and the opening and closing jaw 351 together is an overall cylindrical shape (the diameters of the two ends are equal) or a truncated cone (there is a difference in the diameters of the two ends). It should be noted that when the shape formed by the rotating jaw 341 and the opening and closing jaw 351 together is a cylindrical shape, the shape of the rolled sheet 84 described later is also a cylindrical shape. Of course, after the opening and closing jaw 351 rotates relative to the rotating jaw 341 and opens, the rotating jaw 341 and the opening and closing jaw 351 still together form a cylindrical or truncated cone shape.

[0068] The rotating jaw 341 is disposed on the rotating disk 31 and rotates relative to the rotating disk 31 as the rotating disk 31 rotates. It is easy to understand that the opening and closing jaw 351 and the rotating jaw 341 can be driven by a separate servo motor and by conventional electrical control means, so that the opening and closing jaw 351 rotates relative to the rotating jaw 341, and the rotating jaw 341 rotates relative to the rotating disk 31 as the rotating disk 31 rotates.

[0069] The sheet pressing assembly 36 includes a sheet pressing roller 361 . The sheet pressing roller 361 changes its distance from the rotating clamping jaw 341 as the rotating disk 31 rotates.

[0070] The working principle of the roll forming device 3 is that the upper sheet rotating wheel 19 drives the upper sheet adsorption head 191 to rotate until the upper sheet adsorption head 191 is roughly located at the top of the upper sheet rotating wheel 19. At this time, the glue-coated sheet 83 adsorbed by the upper sheet adsorption head 191 is roughly horizontal; the opening and closing jaws 351 rotate relative to the rotating jaws 341 so that the opening and closing jaws 351 and the rotating jaws 341 clamp the glue-coated sheet 83; the opening and closing jaws 351 and the rotating jaws 341 clamp the glue-coated sheet 83 and rotate with the turntable 31. This process corresponds to the workstation for clamping the glue-coated sheet 83.

[0071] Afterwards, the pressing roller 361 approaches the rotating jaw 341 until it contacts the glue-coated sheet 83, so that the glue-coated sheet 83 gradually adheres to the cylindrical or truncated cone shape of the opening and closing jaw 351 and the rotating jaw 341, until the entire glue-coated sheet 83 adheres to the opening and closing jaw 351 and the rotating jaw 341 to form a rolled sheet 84; this process corresponds to the station for curling the glue-coated sheet 83. It is easy to understand that the glue on the rolled sheet 84 enables it to maintain its shape.

[0072] Afterwards, the sealing claw 38 described later is used to press the portion of the rolled sheet 84 that exceeds the axial length of the rotating clamp 341 against one end of the rotating clamp 341 to achieve sealing. In other words, at this time, one end of the rolled sheet 84 is open and the other end is sealed due to the pressure of the sealing claw 38 to form a sealed rolled sheet 84; this process corresponds to the work station for sealing the rolled sheet 84; and in this process, the pressing roller 361 remains pressed against the glue-coated sheet 83.

[0073] Afterwards, the opening and closing jaws 351 rotate relative to the rotating jaws 341 to loosen the sealed rolled sheet 84, and the pressing roller 361 moves away from the rotating jaws 341 by a large distance, so that the sealed rolled sheet 84 moves along the rotating jaws 341 and detaches from the rotating jaws 341 and the opening and closing jaws 351 through the roll discharge structure 5 described later. This process is the work station for outputting the rolled sheet 84.

[0074] Afterwards, the pressing roller 361 approaches the rotating clamp 341 but still has a small distance from the rotating clamp 341; this process prepares the pressing roller 361 for approaching the preparation station and for the station for clamping the glue-coated sheet 83 in the next cycle.

[0075] By repeating the above process, the roll-shaped sheet 84 can be produced continuously and automatically; during the continuous production process, the turntable 31 always keeps rotating.

[0076] It is easy to understand that all the above-mentioned workstations can achieve better production results, but it does not mean that all the above-mentioned workstations are indispensable to the roll forming device 3; in other words, only the workstation for clamping the glue-coated sheet 83, the workstation for curling the glue-coated sheet 83, and the workstation for outputting the rolled sheet 84 are indispensable workstations.

[0077] As one of the specific embodiments, the clip assembly 34 also includes a rotating connection cylinder 342 and a rotating gear 343 fixedly connected to the rotating clamping claw 341 and the rotating connection cylinder 342 at both ends; the roll forming device 3 also includes a clip fixing plate 32 fixed on the mounting carrier 9, for example, the fixed connection is achieved through the fixing plate mounting column 39; the clip fixing plate 32 is fixedly provided with a rotating rack segment 321 meshing with the rotating gear 343; the rotating connection cylinder 342 is rotatably connected to the turntable 31. For example, the turntable connection carrier 318 is fixed on the turntable 31, and the rotating connection cylinder 342 is rotatably connected to the turntable connection carrier 318 fixed on the turntable 31 through a bearing, so that the rotating connection cylinder 342 is rotatably connected to the turntable 31. It can realize that the rotating clamping claw 341 rotates synchronously with the turntable 31 and has high reliability. The range of the center angle of the rotating rack segment 321 (the center angle relative to the axis of the turntable 31) corresponds to the station of curling the glue-coated sheet 83.

[0078] As one of the specific embodiments, the clamping piece assembly 34 also includes an opening and closing member 354, a clamping claw reset member 358 and a movable clamping claw rod 352 provided with a rotating pin 353; the opening and closing member 354 is provided with a motion steering groove 355 and is linearly slidably connected with the rotating connecting cylinder 342 (extending the linear direction of the axis of the movable clamping claw rod 352), such as a linear slider of the opening and closing member 354 (such as Fig.13As shown, the four blocks at the opposite end of the opening and closing jaws 351 of the opening and closing member 354 are linear sliders) and cooperate with the linear slide grooves (not shown in the drawings) of the rotating connecting cylinder 342 to achieve a linear sliding connection; the rotating pin 353 is embedded in the motion steering groove 355, and it is easy to understand that the motion steering groove 355 is a groove formed by moving along the axis of the moving jaw rod 352 while moving around the axis of the moving jaw rod 352; the moving jaw rod 352 is set in the rotating connecting cylinder 342 and can rotate relative to the rotating connecting cylinder 342 It is easy to understand that the opening and closing clamping jaw 351 can also rotate relative to the rotating clamping jaw 341 accordingly; the clamping jaw reset member 358 respectively abuts against the rotating connecting cylinder 342 and the opening and closing member 354, so that the opening and closing member 354 has a tendency to move away from the rotating clamping jaw 341; the clamp fixing disk 32 is provided with a loose claw boss 322 arranged along the axis of the rotating disk 31, and the loose claw boss 322 can directly or indirectly abut against the opening and closing member 354 to make the opening and closing member 354 move axially (in the direction of the axis of the moving clamping jaw rod 352). For example, the tail end of the opening and closing member 354 is provided with a loose claw abutting member 356, and the loose claw boss 322 indirectly abuts against the opening and closing member 354 through the loose claw abutting member 356, thereby enabling the opening and closing member 354 to move axially. Usually, a bearing (not shown in the drawings) sleeved on the opening and closing member 354 is provided in the loose claw abutting member 356, and the bottom end of the loose claw abutting member 356 is connected to the turntable connecting carrier 318 through a linear guide rail 357 to improve stability. It is easy to understand that the loose claw boss 322 is annular in shape when viewed from the front, and its two ends are transitioned through inclined surfaces. The range of the central angle corresponding to the loose claw boss 322 (the central angle relative to the axis of the turntable 31) corresponds to the station for outputting the rolled sheet 84 and the sheet pressing roller 361 close to the preparation station, and the opening and closing jaws 351 of the two stations are relatively opened and do not clamp the coated sheet 83 when rotating with the rotating jaw 341; the specific process is that the loose claw boss 322 abuts against the opening and closing member 354 to make the opening and closing member 354 move axially, and the moving steering groove 355 abuts against the rotating pin 353 so that the moving jaw rod 352 drives the opening and closing jaw 351 to rotate and loosen. In other working positions, the loose claw boss 322 does not abut against the opening and closing member 354, and the opening and closing member 354 is reset under the elastic force of the claw reset member 358, and the opening and closing claw 351 rotates relative to the rotating claw 341 to close and clamp the rubber-coated sheet 83; and the opening and closing claw 351 and the rotating claw 341 can rotate relative to the rotating disk 31 along with the rotating gear 343. It can be more reliably realized that the opening and closing claw 351 is opened and closed along with the rotation of the rotating disk 31, and the opening and closing claw 351 and the rotating claw 341 rotate relative to the rotating disk 31 as a whole.

[0079] As one of the specific implementations, the clip fixing plate 32 is also provided with a posture control rail 323 which is offset from the rotating rack segment 321 in the axial direction of the turntable 31, and a posture control body 344 which can fit with the posture control rail 323 is fixedly provided at one end of the rotating connecting tube 342. For example, a posture control plate 345 is fixedly provided at one end of the rotating connecting tube 342, and four cylindrical posture control bodies 344 are evenly arranged on the posture control plate 345. Of course, the posture control body 344 can also be a roller; when viewed along the axis of the turntable 31, the posture control rail 323 and the rotating rack segment 321 are surrounded as a whole to form a closed circular ring. It should be noted that in the discharge rack section 324 mentioned later, the middle part of the attitude control rail 323 is provided with a discharge rack section 324 which is staggered from the attitude control rail 323 in the axial direction of the turntable 31, so that the attitude control rail 323 is divided into two sections by the discharge rack section 324. It should also be understood that the attitude control rail 323 and the rotating rack section 321 are surrounded to form a closed circular ring when viewed along the axis of the turntable 31; the discharge rack section 324 can mesh with the rotating gear 343. It can ensure that the rotating jaw 341 has a uniform posture during each rotation of the turntable 31 (one rotation of the turntable 31), and will not be adjusted due to factors such as deadweight, thereby ensuring accurate clamping of the rubber-coated sheet 83.

[0080] As one of the specific embodiments, the sheet pressing assembly 36 also includes a sheet pressing control shaft 362, a sheet pressing extension arm 363 and a sheet pressing slider 364 which are fixedly connected in sequence. The sheet pressing control shaft 362 is rotatably connected to the turntable 31, for example, it is rotatably connected to the turntable connecting carrier 318 fixed on the turntable 31 through a bearing; the sheet pressing roller 361 is directly or indirectly connected to the sheet pressing control shaft 362, and a spacing is provided between the sheet pressing slider 364, the sheet pressing roller 361 and the axial center line of the sheet pressing control shaft 362; the roll forming device 3 also includes a sheet pressing fixed disk 33 fixed on the mounting carrier 9, the sheet pressing fixed disk 33 is provided with an annular (annular refers to the shape where the head and tail are connected) sheet pressing groove 331, the sheet pressing groove 331 includes a supporting section 332 and a spacing section 333, and there is a radius difference between the supporting section 332 and the spacing section 333, and the sheet pressing slider 364 is embedded in the sheet pressing groove 331. It is easy to understand that the abutting section 332 and the spacing section 333 are both annular sectors when viewed from the front, and a smooth transition to the pressing slider 364 is achieved through an inclined surface or the like. It is easy to understand that the clamping plate 32 and the pressing plate 33 can also be an integral component; this embodiment distinguishes the two only for the convenience of explanation. When the pressing slider 364 is located in the abutting section 332 of the pressing slot 331, the pressing roller 361 abuts against the rotating clamp 341 and the rubber-coated sheet 83; when the pressing slider 364 is located in the spacing section 333 of the pressing slot 331, the pressing slider 364 drives the pressing control shaft 362 and the pressing roller 361 to rotate, so that the pressing roller 361 is far away from the rotating clamp 341. It can more reliably achieve that the pressing roller 361 abuts against and approaches the rotating clamp 341 as the turntable 31 rotates.

[0081] As one of the specific embodiments, the pressing assembly 36 also includes a clamping structure 37, which includes a clamping extension body 371 and a roller frame hinge cylinder 374 with a clamping elastic member groove 373, the roller frame hinge cylinder 374 is rotatably connected to the pressing control shaft 362, for example, the roller frame hinge cylinder 374 is fixedly provided with a roller frame hinge cylinder 374, the roller frame hinge cylinder 374 is sleeved on the pressing control shaft 362 so that the roller frame hinge cylinder 374 is rotatably connected to the pressing control shaft 362, the pressing roller 361 is arranged on the roller frame hinge cylinder 374, the clamping extension body 371 passes through the clamping elastic member groove 373, and clamping elastic members 379 are arranged on both sides of the clamping elastic member groove 373, the clamping elastic members 379 are respectively abutted against the clamping elastic member groove 373 so that the clamping extension body 371 has a tendency to be centered relative to the clamping elastic member groove 373. It is easy to understand that in this embodiment, the pressing roller 361 is indirectly connected to the pressing control shaft 362. The pressing control shaft 362 rotates so that the pressing roller 361 is against the rotating clamp 341 through the elastic force of the pressing elastic member 379, which can ensure that the pressing roller 361 has a relatively stable holding force on the rotating clamp 341, thereby ensuring the quality of the curled rubber-coated sheet 83.

[0082] As one of the specific implementations, the roll forming device 3 further includes a sealing claw 38 with a rotating power, and the sealing claw 38 can abut or approach one end of the rotating clamping claw 341 to seal one end of the roll-shaped sheet 84 .

[0083] As one of the specific embodiments, the tablet pressing chute 331 further includes a preparatory section 334, which is located between the end of the spacing section 333 and the beginning of the abutting section 332, and the radius of the preparatory section 334 is located between the radius of the abutting section 332 and the radius of the spacing section 333. It is easy to understand that the abutting section 332, the spacing section 333, and the preparatory section 334 are connected head to tail in sequence to form an annular tablet pressing chute 331. The necessary diameter of the turntable 31 can be reduced, thereby controlling the overall size of the device.

[0084] The roll forming device 3 includes a turntable 31, a rotating jaw 341 and an opening and closing jaw 351 that can rotate relative to the rotating jaw 341. The turntable 31 has a rotational power; the rotating jaw 341 and the opening and closing jaw 351 together form a cylindrical or truncated cone shape. The rotating jaw 341 is set on the turntable 31 and rotates relative to the turntable 31 as the turntable 31 rotates.

[0085] The roll discharging structure 5 includes a roll discharging wheel 51 having a rotational power and a cylindrical shape.

[0086] The axis of the roll discharge wheel 51 is perpendicular to the rotating clamping claw 341 and can abut against the rotating clamping claw 341 .

[0087] The working principle of the roll discharge structure 5 is that when outputting the roll sheet 84 at the work station, the roll discharge wheel 51 abuts against the rotating clamp 341 and the roll sheet 84 thereon, and the roll discharge wheel 51 relies on the friction force to move the roll sheet 84 along the rotating clamp 341 until it is separated from the rotating clamp 341, and the roll sheet 84 falls into the discharge bucket 52 described later, thereby being able to continuously separate the roll sheet 84 from the rotating clamp 341.

[0088] As one of the specific implementations, during the process of the roll-discharging wheel 51 abutting against the rotating jaw 341, the opening and closing jaw 351 is in a state of being opened relative to the rotating jaw 341. It is easy to understand that, in the previous station for clamping the glue-coated sheet 83 and the station for curling the glue-coated sheet 83, the narrower rectangular portion of one side of the glue-coated sheet 83 is clamped by the rotating jaw 341 and the opening and closing jaw 351, and the narrower rectangular portion is located on the inner wall of the rolled sheet 84 after the rolled sheet 84 is formed and does not fit the inner wall of the rolled sheet 84. Therefore, during the process of the discharge wheel 51 abutting against the rotating jaw 341, the opening and closing jaw 351 is open relative to the rotating jaw 341; there is no part in the inner wall of the rolled sheet 84 that is clamped by the opening and closing jaw 351 and the rotating jaw 341, which can ensure that the rolled sheet 84 is separated from the rotating jaw 341.

[0089] As one of the specific implementations, during the process of the roll-discharging wheel 51 and the rotating jaw 341 being attached, the rotating jaw 341 rotates relative to the rotating disc 31 while rotating along with the rotating disc 31. The roll-shaped sheet 84 sleeved on the rotating jaw 341 is driven by the roll-discharging wheel 51 to move axially along the rotating jaw 341, and rotates relative to the rotating jaw 341, so that the roll-shaped sheet 84 moves spirally relative to the rotating jaw 341, so that the corresponding portion (i.e., the narrower rectangular portion) of the inner wall of the roll-shaped sheet 84 clamped by the rotating jaw 341 and the opening and closing jaw 351 can be attached to the inner wall of the roll-shaped sheet 84.

[0090] As one of the specific implementations, the rotating jaw 341 is directly or indirectly fixedly connected to the rotating gear 343, and the mounting carrier 9 is fixedly provided with a discharge rack segment 324 that can mesh with the rotating gear 343, for example, the discharge rack segment 324 is fixed on the clamp fixing plate 32. When the clamp assembly 34 passes through the discharge rack segment 324, the rotating gear 343 meshes with the discharge rack segment 324, and the rotating jaw 341 can be more reliably rotated relative to the rotating disk 31 while rotating with the rotating disk 31.

[0091] As one of the specific implementations, the roll discharging wheel 51 is elastic, such as made of silicone, etc., so as to ensure that the roll discharging wheel 51 has a large friction force on the roll sheet 84 and ensures that the roll sheet 84 is separated from the rotating clamp 341 .

[0092] As one of the specific implementations, the thickness of the roll discharging wheel 51 is greater than the maximum diameter of the cylindrical or truncated cone shape formed by the rotating clamping jaw 341 and the opening and closing clamping jaw 351 , so as to ensure that the roll-shaped sheet 84 is separated from the rotating clamping jaw 341 .

[0093] As one of the specific embodiments, the roll discharge structure 5 further includes a discharge bucket 52, which includes a discharge blocking wall 522 and an inclined bottom wall 521 inclined relative to the horizontal plane, and an angle is set between the discharge blocking wall 522 and the rotating clamp 341, for example, the discharge blocking wall 522 is perpendicular to the rotating clamp 341. After the roll sheet 84 discharged by the roll discharge wheel 51 is blocked by the discharge blocking wall 522, it is transported to the output power belt 92 through the inclined bottom wall 521, which can prevent the roll sheet 84 from flying around. Usually, the discharge bucket 52 also includes a guide wall 523 and a shielding wall 529.

[0094] As one of the specific implementations, the roll discharging structure 5 is provided with a notch 524 facing the output end of the inclined bottom wall 521 (i.e., the lower end of the inclined bottom wall 521), and a ventilation device (not shown in the drawings), such as an exhaust fan, is provided at the notch 524 to blow air toward the output end of the inclined bottom wall 521, so as to ensure that the roll-shaped sheet 84 is discharged from the discharge hopper 52.

[0095] The continuous roll forming device of the utility model also includes a synchronous drive structure 7; the synchronous drive structure 7 includes a synchronous drive motor 71, and the synchronous drive motor 71 synchronously drives any at least two of the upper sheet power wheel 11, the sheet forming cutter 12, the buffer belt 13, the upper sheet rotating wheel 19, and the turntable 31. In other words, any at least two of the upper sheet power wheel 11, the sheet forming cutter 12, the buffer belt 13, the upper sheet rotating wheel 19, and the turntable 31 are driven by the same drive source, which is the synchronous drive motor 71. It can reduce the dependence on electrical control, reduce costs, and improve equipment reliability.

[0096] like Figure 5 , 9 As shown, the specific implementation method is as follows: the synchronous drive structure 7 also includes an upper sheet synchronous structure 72, a rotating disk synchronous structure 73 and a pusher claw synchronous structure 74. The upper sheet synchronous structure 72 includes an upper sheet synchronous wheel 721, an upper sheet synchronous belt 722, a transition belt synchronous wheel 723, an upper sheet synchronous tensioning wheel 724 and an upper sheet synchronous transition wheel 725. The rotating disk synchronous structure 73 includes a rotating disk transmission wheel 731 and a rotating disk driving wheel 732. The pusher claw synchronous structure 74 includes a pusher claw transmission belt 741, a pusher claw synchronous wheel 742 and a pusher claw synchronous belt 743.

[0097] The output end of the synchronous drive motor 71 drives the reduction output wheel 711 through gears or the like; the reduction output wheel 711 is fixedly connected to the upper film rotating wheel 19 and directly drives the upper film rotating wheel 19 to rotate.

[0098] The reduction output wheel 711 drives the turntable driving wheel 732 through the turntable transmission wheel 731 and further drives the turntable power shaft 319 and the turntable 31 to rotate.

[0099] The pusher dog transmission belt 741 passes through the turntable driving wheel 732 and the pusher dog synchronous wheel 742 to drive the pusher dog synchronous wheel 742. The pusher dog synchronous wheel 742 is fixedly connected to the pusher dog power shaft 389. For the embodiment with multiple sealing pusher dogs 38, each sealing pusher dog 38 can also be connected by a belt, a synchronous belt, etc. and synchronously driven by the pusher dog power shaft 389.

[0100] The speed reduction output wheel 711 drives the upper sheet synchronous wheel 721. The upper sheet synchronous wheel 721 drives the upper sheet output power wheel 149 through a belt, a synchronous belt, etc.

[0101] The upper sheet synchronous wheel 721 drives the sheet forming power wheel 122 and the transition belt synchronous wheel 723 through the upper sheet synchronous belt 722. The transition belt synchronous wheel 723 drives the upper sheet synchronous transition wheel 725 through the upper sheet synchronous belt 722. The upper sheet synchronous transition wheel 725 drives the cache belt power wheel 139 through a belt, synchronous belt, etc. The cache belt power wheel 139 is meshed with the transition power wheel 159 through gears.
