Abstract
Description
Technical Field
[0001] This invention relates to paper cup or paper bowl forming equipment. Background Technology
[0002] The horizontal high-speed paper cup or bowl forming machine can form paper sheets to make paper cups or bowls. However, the station layout of this high-speed forming machine is not reasonable enough, occupying a large space and having low space utilization. Moreover, its main drive structure layout is unreasonable and not compact enough.
[0003] The forming machine shapes fan-shaped paper sheets into paper cups or bowls. The cup clamping mechanism in the forming machine uses a flipping cup clamp (flipping and opening / closing action) to cooperate with the mold forming process. The flipping cup clamp wraps the paper sheet onto the mold (i.e., the cup mold). To ensure stable wrapping and a better forming effect, the cup clamping mechanism is equipped with a lifting pressure strip. The pressure strip rises to press the paper sheet against the underside of the mold before the flipping cup clamp wraps it. The pressure strip requires an additional power source for lifting, resulting in lower efficiency and more complex control. There are two flipping cup clamps, left and right, that work together to open and close. Each flipping cup clamp is connected to a corresponding linkage, which drives the flipping cup clamp to flip and open / close. Ensuring stable lifting and swinging of the linkage, and isolating it from dust and oil, is quite difficult when the linkage is lifting and swinging.
[0004] In forming machines, the rolling equipment rolls the bottom of formed paper cups or bowls to compact, emboss, or texture them. The bearings of the rolling rollers have a relatively short lifespan during use. Currently, rolling equipment has a complex structure, is difficult to assemble, and has poor operational stability. The corresponding transmission mechanism is also complex, and its stability needs improvement to meet further speed requirements. The rolling rollers are mounted on a movable block device, which drives their eccentric movement. The movable block device cooperates with a rolling shaft with a wedge-shaped section. The rolling shaft rotates and moves axially, while the rolling rollers roll against a die. When the rolling equipment is designed with oil lubrication, it is necessary to prevent lubricating oil leakage from contaminating the paper container at the rolling rollers, and also to prevent paper dust at the rolling rollers from entering the oil circuit and affecting transmission. The rolling rollers are driven by the rolling shaft, which needs both axial movement and rotation; ensuring the stable operation of the rolling shaft is crucial.
[0005] The forming machine has an edge-rolling assembly, on which edge-rolling devices (such as a top edge-rolling device or a bottom edge-rolling device) are installed to roll the corresponding bottom and top edges of the paper tube. The stability of the edge-rolling assembly affects the edge-rolling effect and speed. Summary of the Invention

[0053] This embodiment of the horizontal high-speed paper cup or paper bowl forming machine includes a four-station rotary paper feeding mechanism 1, a seven-station main rotary tower forming mechanism 2, and a seven-station auxiliary rotary tower forming mechanism 3. The rotary paper feeding mechanism 1 adopts a four-station layout, meaning that four gripper devices are installed on the rotary paper feeding mechanism and work in 90-degree increments. The main rotary tower forming mechanism 2 adopts a seven-station layout, with seven horizontal main tower molds (with paper cups fitted on the outside) on the main rotary tower, working in seven equal increments. The main rotary tower forming mechanism is equipped with a corresponding arc-surface indexing cam mechanism (including A cylindrical indexing cam) to drive the main rotary tower to rotate in seven equal increments. The auxiliary rotary tower forming mechanism 3 adopts a seven-station layout, with seven horizontal auxiliary tower molds (with paper cups fitted inside) on the auxiliary rotary tower, working in seven equal increments. The auxiliary rotary tower forming mechanism is equipped with a corresponding cylindrical indexing cam mechanism (including B cylindrical indexing cam) to drive the auxiliary rotary tower to rotate in seven equal increments. The main rotating tower forming mechanism and the auxiliary rotating tower forming mechanism are existing technologies. The present invention aims to arrange and lay out their workstations in a completely new way.
[0054] The seven-station main rotating tower forming mechanism 2 has a bottom punching station, a paper feeding and connecting station, a first cup bottom preheating station, a second cup bottom preheating station, a bottom rolling station, a rolling station, and a main and auxiliary tower connecting station arranged in a circumferential sequence.
[0055] The seven-station auxiliary rotating tower forming mechanism 3 has a main and auxiliary tower connection station, a cup mouth lubrication station, a pre-winding station, a first final winding station, a second final winding station, a cup exiting station, and a reserved empty station arranged in a circumferential sequence.
[0056] The circumferential arrangement of the seven-station main rotary tower forming mechanism 2 is opposite to that of the seven-station auxiliary rotary tower forming mechanism 3. The seven-station main rotary tower forming mechanism 2 and the seven-station auxiliary rotary tower forming mechanism 3 share the main and auxiliary tower connection station. The four-station turntable paper feeding mechanism 1 is connected to the paper feeding connection station.
[0057] The new 4-7-7 workstation layout is more rational, compact, and efficient in space utilization. This layout can accommodate the forming of round, square, and oval paper cups. Corresponding devices and assemblies are configured within this 4-7-7 layout, resulting in a rational and compact structure. The adjacent placement of the first and second cup bottom preheating stations ensures good preheating performance and saves energy.
[0058] Each workstation will be equipped with a corresponding assembly or mechanism. Specifically, the bottom die punching station is equipped with a bottom die punching assembly 4; the paper feeding and connecting station is also equipped with a cup clamping mechanism 5; the first cup bottom preheating station is equipped with a first cup bottom preheating assembly 6; the second cup bottom preheating station is equipped with a second cup bottom preheating assembly 7; the bottom roll assembly is equipped with a bottom roll assembly 8; the rolling station is equipped with a rolling assembly 9; the cup mouth lubrication station is equipped with a cup mouth lubrication assembly 10; the pre-winding station is equipped with a pre-winding assembly 11; the first final roll assembly is equipped with a first final roll assembly 12; the second final roll assembly is equipped with a second final roll assembly 13; and the cup ejection station is equipped with a cup ejection assembly 14.
[0059] The turntable paper feeding mechanism 1 adopts a four-station layout, that is, four gripper devices are set on the turntable paper feeding mechanism and work together by rotating 90 degrees in increments.
[0060] In this embodiment, the four-station turntable paper feeding mechanism 1 includes a turntable 1A, which is connected to a rotary transmission device 20A. The rotary transmission device 20A drives the turntable to rotate. Four gripper devices 2A are arranged on the turntable 1A at indexing intervals. The gripper devices 2A can rotate with the turntable 1A at indexing intervals. The turntable corresponds to the four stations. The indexing and rotation of the turntable 1A are coordinated with the rotation, making the layout of the four stations more reasonable. The gripper devices clamp and release the paper sheets that are fed in.
[0061] An opening is provided at the rotation center of the turntable 1A, and a lifting tooth-opening shaft 3A is installed at the opening. The rotation of the turntable 1A does not affect the lifting and lowering of the lifting tooth-opening shaft 3A. A tooth-opening plate 4A is connected to the lifting tooth-opening shaft 3A and is located above the turntable 1A. The tooth-gripping device includes a paper-gripping tooth 5A, which is hinged to a first mounting base 6A. The first mounting base is connected to the turntable, and the paper-gripping tooth can swing on the first mounting base. Below the paper-gripping tooth 5A is a paper-supporting part 7A located on the turntable. When the paper-gripping tooth 5A presses against the paper-supporting part 7A, it engages to grip the paper. The paper-gripping tooth 5A is also equipped with a paper-gripping reset device 8A, which keeps the paper-gripping tooth in a paper-gripping state with the paper-supporting part. The tooth-opening plate engages with the paper-gripping tooth drive, and the tooth-opening plate 4A rises and falls with the lifting tooth-opening shaft 3A. When descending, the tooth-opening plate presses down to open the paper-gripping tooth for paper input or output. At stations requiring opening of the gripper plate, such as the paper feeding and output stations, there are corresponding gripper plates. At the paper feeding station, the paper is fed to and clamped by the gripper device on the turntable. At the output station, the gripper device releases the paper for subsequent processing. The rotary transmission device 20A includes a servo motor 21A, which drives the turntable to rotate. The servo motor drives the turntable to rotate by a corresponding angle. Four gripper devices are set on the turntable. The servo motor drives the turntable to rotate 90 degrees each time. The gripper plate corresponds to and cooperates with the gripper devices that move to the front and rear stations. The layout is reasonable and the structure is compact. Figure 4 When the gripper is positioned at the front and rear stations, it corresponds to the paper feeding and output stations, respectively. The left and right positions correspond to the idle and heating stations, respectively. This turntable paper feeding mechanism offers faster speeds, meeting the demands of high-speed production. Driven by a servo motor, the turntable rotates, achieving indexing and turning. Its simple and compact structure ensures stable operation to meet high-speed requirements. A limit block 17A can also be added. The paper support section 7A utilizes the turntable edge or is fitted with a paper support plate. The lifting gripper shaft 3A is also equipped with a lifting reset device 19A (such as a spring).
[0062] Servo motor 21A drives and connects to the first output wheel 9A. The turntable 1A is connected to the first input wheel 10A. The turntable and the first input wheel rotate synchronously. The first output wheel 9A and the first input wheel 10A are driven by pulleys, sprockets, or gears. The corresponding transmission methods are belt drive, chain drive, and gear meshing. The diagram shows a pulley and belt with a tensioning pulley 34A. The first output wheel 9A is mounted on a hollow support shaft 11A. A slewing bearing 12A is located between the hollow support shaft and the first output wheel. A lifting threaded shaft 3A is configured within the hollow support shaft and connected to the second cam device 27. The turntable rotates on the hollow support shaft, and the lifting threaded shaft moves up and down within the hollow support shaft, coordinating the rotation of the turntable with the movement of the lifting threaded shaft. The lifting threaded shaft is driven to move up and down by an upgraded transmission device within the hollow support shaft. The servo motor 21A can be configured with a reducer 22A and connected to the first output wheel 9A. Using a servo motor results in faster speed and response. A hollow support shaft is used for support and is fixed to the frame 31A or a fixed base. The hollow support shaft is connected to the frame or fixed base via a second mounting base 32A. The servo motor is connected to the hollow support shaft or the frame via a connecting plate 33A.
[0063] The second cam device 27 includes a transmission cam, which is located below the turntable. The transmission cam is in drive with the lifting and lowering threaded shaft, and the lifting and lowering of the threaded shaft is driven by the transmission cam. The second cam device 27 is connected to the main drive mechanism.
[0064] The paper-clamping gripper 5A is connected to the rotating shaft 18A, which is hinged to the first mounting base 6A. The first mounting base 6A is connected to the turntable 1A. A pressure-bearing component 15A is installed on the rotating shaft 18A, and a pressure-applying component 16A is connected to the tooth-opening plate 4A. During engagement, the pressure-applying component applies pressure to the pressure-bearing component, and the rotation of the rotating shaft 18A drives the paper-clamping gripper 5A to rotate, thus opening the teeth. A paper-clamping gripper is installed at each end of the rotating shaft to ensure stable paper clamping. The paper-clamping reset device 8A includes a paper-clamping reset spring, which is located below the pressure-bearing component. The paper-clamping reset device causes the rotating shaft to rotate back to its original position. The pressure-bearing component 15A has a pressure-bearing bearing that is pressurized for smoother engagement; the pressure-applying component 16A is an adjusting bolt, whose length can be adjusted to meet different needs.
[0065] The molding machine also includes a main drive mechanism, which comprises a main motor 17, a main shaft 18, a first transmission auxiliary shaft 19, and a second transmission auxiliary shaft 20. The main motor 17 is a servo motor, and is connected to the main shaft 18. The main motor 17 drives the main shaft 18 to rotate, and is driven by a gearbox 171 (containing a first bevel gear pair). The main shaft 18 is connected to the A cylindrical indexing camshaft 21 of the seven-station main rotary tower molding mechanism and the B cylindrical indexing camshaft 22 of the seven-station auxiliary rotary tower molding mechanism. The main shaft 18 drives the A and B cylindrical indexing camshafts to rotate, and the corresponding cylindrical indexing cams rotate in coordination to drive the indexing rotation. The A-cylindrical indexing camshaft, B-cylindrical indexing camshaft, main shaft 18, and second transmission auxiliary shaft 20 are parallel. The first transmission auxiliary shaft is connected between the A-cylindrical indexing camshaft and the second transmission auxiliary shaft, and the first transmission auxiliary shaft is perpendicular to the second transmission auxiliary shaft. The first transmission auxiliary shaft is connected to the A-cylindrical indexing camshaft via a second bevel gear pair, and to the B-cylindrical indexing camshaft via a third bevel gear pair. This main transmission mechanism has a reasonable and compact layout, which can match a 4-7-7 workstation layout. The main shaft 18, the first transmission auxiliary shaft 19, the second transmission auxiliary shaft 20, the A-cylindrical indexing camshaft, and the B-cylindrical indexing camshaft are all located in the same plane. The first transmission auxiliary shaft is located between the main rotary tower forming mechanism and the auxiliary rotary tower forming mechanism. A cam structure is set on the first transmission auxiliary shaft for other transmissions. For example, a cam assembly is set on the first transmission auxiliary shaft. The cam assembly is in drive cooperation with the pressure spring of the main rotary tower. The pressure spring drives the pressure block to rise and fall, which can buffer the downward pressure of the corresponding pressure spring of each horizontal mold. The main shaft is connected to the A cylindrical indexing camshaft via a helical gear pair or a belt drive pair, while the main shaft is connected to the B cylindrical indexing camshaft via a chain and sprocket pair. This design facilitates assembly and ensures a high degree of fit.
[0066] The punching die assembly 4 has a punching drive wheel device 41; the first cup bottom preheating assembly 6 has a first cup bottom preheating drive wheel device 61; the second cup bottom preheating assembly 7 has a second cup bottom preheating drive wheel device 71; the rolling assembly 8 has a rolling bottom drive wheel device 81; the rolling assembly 9 has a rolling drive wheel device 91; the cup mouth lubrication assembly 10 has a lubrication drive wheel device 101; the pre-rolling assembly 11 has a pre-rolling drive wheel device 111; the first final roll assembly 12 has a first final roll drive wheel device 121; and the second final roll assembly 13 has a second final roll drive wheel device 131. Each drive wheel device uses a sprocket assembly, which provides good transmission effect and more stable high-speed operation. Each drive wheel device is configured on a rotating vertical shaft, and the corresponding components are driven by an eccentric wheel on the rotating vertical shaft to perform reciprocating motion.
[0067] The main shaft 18 is driven by the first transmission wheel assembly 23, which transmits power to the first transmission wheel assembly 23. The main shaft and the first transmission wheel assembly are connected via a fourth bevel gear pair.

[0069] The first cam device 26 is connected to the second transmission shaft 20, and the first cam device is connected to the cup clamping mechanism. The second transmission shaft 20 is also connected to a second cam device 27, which is connected to the lifting shaft at the center of the turntable of the four-station turntable paper feeding mechanism. The transmission cam of the second cam device is connected to the second transmission shaft. The forming machine also has a cup bottom oiling station between the second cup bottom preheating station and the bottom rolling station. The cup bottom oiling station is equipped with a cup bottom oiling device, which includes a cup bottom oiling tray. After oiling, the bottom rolling is smoother. During the rotation of the main rotary tower forming mechanism, the paper tube on it will contact the cup bottom oiling device without stopping.
[0070] The bottom punch assembly 4 includes a bottom forming device, which includes a bottom punching drive hollow shaft 1B and a forming drive shaft 2B. The bottom punching drive hollow shaft 1B and the forming drive shaft 2B are arranged horizontally. The front end of the forming drive shaft 2B is connected to a forming male mold 3B, and the front end of the bottom punching drive hollow shaft 1B is connected to a bottom punching male cutter 4B. A cutter holder 5B can be provided on the bottom punching drive hollow shaft 1B for mounting the bottom punching male cutter 4B.
[0071] To ensure a compact structure, stable operation, and high-speed performance, first guide sleeves 6B are installed on the outer sides of the front and rear of the hollow shaft 1B for bottom-feeding transmission. These first guide sleeves, made of copper, provide movable support at the front and rear of the shaft. This creates double support during lateral movement, resulting in more stable operation. The forming transmission shaft 2B is located inside the hollow shaft 1B. Second guide sleeves 7B, also made of copper, are installed on the outer sides of the front and rear of the forming transmission shaft. These second guide sleeves, located between the hollow shaft 1B and the forming transmission shaft 2B, provide movable support at the front and rear of the forming transmission shaft within the hollow shaft. This double support during lateral movement further enhances stability. The connection between the hollow shaft and the forming transmission shaft is compact, rationally laid out, and operates stably, meeting the requirements of high-speed operation. Below the bottom-punching transmission hollow shaft 1B is a first rotary drive vertical shaft 8B. The first rotary drive vertical shaft 8B is connected to the bottom-punching transmission hollow shaft 1B and the forming transmission shaft 2B respectively. The first rotary drive vertical shaft 8B cooperates in the transmission, which has higher stability, avoids vibration, and meets the high-speed requirements.
[0072] The first rotary drive shaft 8B is equipped with a cam transmission mechanism and a first eccentric wheel transmission mechanism. The bottom-punching transmission hollow shaft has a lower hollow 9B, and the cam transmission mechanism is located at the lower hollow 9B. The cam transmission mechanism is connected to the forming transmission shaft 2B through the lower hollow. The first eccentric wheel transmission mechanism is connected to the bottom-punching transmission hollow shaft. The transmission structure is reasonable and stable, meeting the speed increase requirements. The cam transmission mechanism includes a cam 10B, which is connected to the first rotary drive shaft 8B and is driven to rotate by the first rotary drive shaft. The first eccentric wheel transmission mechanism includes a first eccentric wheel 11B, which is connected to the first rotary drive shaft and is driven to rotate by the first rotary drive shaft. The cam 10B is located above the first eccentric wheel.
[0073] The cam 10B of the cam transmission mechanism is preferably a conjugate cam. The forming transmission shaft 2B is provided with a first front roller 12B and a first rear roller 13B. The first front roller 12B is located on the front side of the conjugate cam, and the first rear roller 13B is located on the rear side of the conjugate cam. The first front roller and the first rear roller are respectively connected to the conjugate cam for transmission. The first front roller and the first rear roller on the forming transmission shaft are driven by the conjugate cam to make the forming transmission shaft move forward and backward. The first front roller, the first rear roller and the conjugate cam are located at the lower hollow of the bottom punching transmission hollow shaft 1B, and are driven by the lower hollow 9B.
[0074] An anti-rotation device is installed between the forming drive shaft and the bottom-punch hollow drive shaft to prevent the forming drive shaft from rotating within the bottom-punch hollow drive shaft, thus making the operation more stable. For example, the anti-rotation device includes a transverse elongated hole 14B, an anti-rotation block 15B, and an anti-rotation wheel assembly 16B. The transverse elongated hole is located on the upper side wall of the bottom-punch hollow drive shaft 1B. The anti-rotation block is connected to the forming drive shaft 2B. The anti-rotation wheel assembly is located on the outside of the bottom-punch hollow drive shaft. The anti-rotation block passes through the transverse elongated hole and is clamped by the anti-rotation wheel assembly, which provides a guiding fit. This device guides the forming drive shaft during lateral movement, preventing it from rotating. During lateral movement, the anti-rotation block is clamped by the anti-rotation wheel assembly and moves laterally forward and backward.
[0075] The first eccentric wheel of the first eccentric wheel transmission mechanism is either a separate or integrated structure with the first rotary drive shaft 8B. The figure shows an integrated structure of the first eccentric wheel 11B and the first rotary drive shaft 8B. Preferably, the first eccentric wheel 11B is connected to a first sleeve 17B. The sleeve hole of the first sleeve 17B is fitted onto the first eccentric wheel 11B. When the first eccentric wheel 11B rotates with the first rotary drive shaft 8B, it causes the first sleeve 17B to oscillate. The rear end of the first sleeve is a first connecting part 18B. The left and right sides of the first connecting part are respectively provided with pull rod holes, and a first pull rod 19B is installed in each pull rod hole; that is, a first pull rod is installed in the left pull rod hole and a first pull rod is installed in the right pull rod hole. A first spring 20B and a first limiting part 21B are provided on the first pull rod 19B. The first limiting part and the first spring are respectively located on the front and rear sides of the pull rod hole. The first spring and the first limiting part cooperate to keep the first pull rod stably connected in the corresponding pull rod hole of the first connecting part, and the first pull rod can move slightly relative to the position of the pull rod hole when the first sleeve is driven to swing. The first spring is pre-tightened on the pull rod by a pre-tightening nut 53B. The rear part of the punching drive hollow shaft 1B is connected to a first transmission block 22B. The first transmission block 22B is hinged to the first connecting seat 23B below. The left and right sides of the first connecting seat 23B are respectively connected to the left and right first pull rods of the first connecting part 18B. The first pull rods are respectively connected to the left and right sides of the first connecting seat. When the first eccentric wheel 11B drives the first sleeve 17B to swing, the first pull rod 19B drives the first connecting seat 23B to swing and move back and forth. The first connecting seat drives the first transmission block 22B to move forward and backward. The punching drive hollow shaft 1B connected to the first connecting seat also moves forward and backward. The first eccentric wheel transmission mechanism has a reasonable structure, stable operation, and can meet high-speed requirements.
[0076] A bearing 24B is provided between the first eccentric wheel 11B and the sleeve hole to facilitate smoother transmission of the first eccentric wheel 11B to the first sleeve 17B. A hinge hole is provided on the first connecting seat 23B, and a bearing 25B (such as a double-row angular contact ball bearing) is provided between the first transmission block 22B and the hinge hole to facilitate smoother transmission between the first connecting seat 23B and the first transmission block 22B. A swing clearance is provided between the pull rod hole and the first pull rod 19B, allowing the first pull rod to swing within the pull rod hole. The first connecting seat 23B has through holes that connect to the first pull rod. Locking nuts 26B are provided on both sides of the through holes and on the first pull rod. Adjusting the position of the locking nuts 26B on both sides changes the relative position of the first pull rod and the first connecting seat, thereby adjusting the starting position of the forward and backward movement of the punching drive hollow shaft to meet the needs of reinstalling the punching tool after grinding.
[0077] A fixing frame 34B is provided in front of the male punch 4B, and a female punch 35B is mounted on the fixing frame 34B. The male and female punches cooperate to punch the bottom. A molding female mold 36B is mounted on the fixing frame 34B, and the molding male mold cooperates with the molding female mold to form the shape. The female punch, male punch, molding female mold, and molding male mold are arranged coaxially. The female punch and molding female mold can be integrated or separate; the figure shows an integrated design for easier processing and assembly.
[0078] There are many structures for mounting the punching die and the molding die, among which the following structure is preferred: The mounting frame includes a rear plate and a front plate. The front plate is connected to the rear plate by fasteners (such as screws). The rear plate has a groove between the front plate and the rear plate, which allows the paper material to pass through vertically. The front plate has an assembly through hole for mounting the punching die and the molding die. The assembly through hole is a stepped hole. The punching die and the molding die are assembled and connected to the front plate by fasteners (such as screws).
[0079] The first guide sleeve 6B is clamped and supported by the upper fixed seat 27B and the lower fixed seat 28B. The first rotary drive shaft 8B is rotatably supported by the lower fixed seat. A bearing 29B is provided between the first rotary drive shaft and the lower fixed seat. The upper fixed seat and the lower fixed seat are combined to form a seat body. The lower part of the first rotary drive shaft 8B is connected to the bottom-punching transmission wheel device 41.
[0080] In this embodiment, the cup clamping mechanism 5 includes a mounting shaft 2C, which is mounted on the first support frame 1C. Flipping cup clamps 3C and 4C are connected to the mounting shaft. The flipping cup clamps 3C and 4C are connected to connecting rods 9C and 10C, which drive the flipping cup clamps to flip on the mounting shaft. The flipping cup clamps include a left cup clamp and a right cup clamp, which are respectively driven to flip by corresponding connecting rods (including the left connecting rod and the right connecting rod). The opening and closing action of the flipping cup clamps cooperates with mold forming.
[0081] To ensure greater stability of connecting rods 9C and 10C during swinging and lifting, and to guarantee high-speed operation, in this embodiment, the first support frame 1C includes a transverse partition 14C. The transverse partition 14C has a movable hole 51C, within which a sliding sleeve 52C is housed. A first joint bearing 53C is housed within the sliding sleeve 52C. An upper cover 54C is connected above the transverse partition 14C, and a lower support 55C is connected below it. The sliding sleeve 52C slides within the movable hole 51C and the lower support 55C, with the upper cover 54C and the lower support 55C clamping the sliding sleeve 52C within the movable hole 51C for sliding. The first joint bearing 53C moves with the sliding sleeve within the sliding sleeve 52C. The upper cover 54C... An upper movable channel 56C is provided for the connecting rod to pass through, and a lower movable channel 57C is provided on the lower support 55C for the connecting rod to pass through, so that the connecting rod can connect with the guide sleeve 58C in the first joint bearing in the movable hole, so as to facilitate the lifting and swinging of the connecting rod, and to facilitate the transmission connection between the connecting rod and the first cam device 26 below. The guide sleeve 58C is set in the inner hole of the first joint bearing 53C, that is, the guide sleeve is connected in the inner hole of the inner ring of the first joint shaft. The connecting rods 9C and 10C are connected and configured in the corresponding guide sleeves 58C, and the connecting rods slide axially relative to each other in the guide sleeves. When the inner ring of the first joint bearing rotates in the outer ring, the guide sleeve is supported by the first joint bearing to rotate, and the connecting rod moves relative to each other in the guide sleeve. Different thickness specifications of the lower support are changed to adjust the position of mating with the mold.
[0082] Connecting rods 9C and 10C can slide axially within the guide sleeve 58C on the first joint bearing. When the connecting rod is driven to swing and rise, it can slide axially within the guide sleeve in the first joint bearing. It also cooperates with the first joint bearing to slide with the sliding sleeve in the movable hole, and the inner ring of the first joint bearing rotates in the outer ring, making the connecting rod more stable during swinging and rising, thus meeting the requirements of high-speed operation.
[0083] The flip cup clamps 3C and 4C are hinged to the mounting shaft 2C, allowing them to flip and open / close. For example, the flip cup clamps 3C and 4C are fitted onto the mounting shaft, and a rotating bearing is provided between the flip cup clamps and the mounting shaft for smoother rotation. The mounting shaft is located on the support plate 12C of the first support frame 1C, and the support plate 12C is connected to the transverse partition 14C. A second joint bearing 24C and 30C provide a transmission connection between the connecting rod and the flip cup clamp. The second joint bearing is connected to the upper end of the connecting rods 9C and 10C, and the flip cup clamp is then connected to the second joint bearing.
[0084] The lower end of the connecting rod is connected to the third joint bearings 26C and 32C, which are used for transmission connection to drive the connecting rods 9C and 10C to rise, fall, and swing. The connecting rod is also connected to the rocker arms 36C and 38C, which are hinged to the fixed seats 37C and 39C. The rocker arms are connected to the first cam device 26, which drives the rocker arms to reciprocate on the fixed seats 37C and 39C. The swinging of the rocker arms 36C and 38C drives the connecting rods 9C and 10C to reciprocate, resulting in reciprocating swinging and rising / falling motions. The first cam device 26 includes conjugate cams 41C and 42C, which respectively cooperate to drive the rocker arms 36C and 38C to reciprocate. The rocker arms have two sets of rotors that cooperate with the conjugate cams for transmission, resulting in more stable transmission and meeting the requirements of higher speed operation. The rocker arms also have a drive shaft connected to the third joint bearings 26C and 32C, realizing the transmission connection between the connecting rod and the rocker arms. Conjugate cams 41C and 42C are connected to the second transmission shaft 20.
[0085] The upper end face of the sliding sleeve 52C is slidably engaged with the upper cover 54C, and the lower end face of the sliding sleeve 52C is slidably engaged with the lower support 55C.
[0086] The upper end face of the sliding sleeve 52C maintains a sliding seal contact with the upper cover 54C at all times, and / or the lower end face of the sliding sleeve 52C maintains a sliding seal contact with the lower support 55C at all times. When the sliding sleeve slides within the movable hole between the upper cover and the lower support, the sliding sleeve will maintain a sliding seal contact with the upper cover or the lower support, or the upper cover and the lower support, to prevent lubricating oil from the transmission part below the partition from splashing and contaminating the upper part of the partition, and to prevent paper dust and paper powder from the forming part above the partition from spreading to the lower part of the partition and affecting the transmission part. In the figure, the upper movable channel on the upper cover is a through hole (such as a stepped through hole), and the diameter of the through hole is smaller than the diameter of the movable hole.
[0087] For more stable sealing, a paper-pressing strip 5C is provided between the flip cup clamps 3C and 4C. The paper-pressing strip 5C is located above the mounting shaft 2C and is connected to the lifting shaft 6C. The lifting shaft 6C is equipped with a descent transmission part 7C, which works in conjunction with the flip cup clamp's reversal transmission. The lifting shaft 6C is also connected to an upward reset device 8C. When the flip cup clamp reverses, it will cause the descent transmission part 7C to descend, and the lifting shaft will also descend; when the flip cup clamp flips upward, the upward reset device 8C will cause the lifting shaft 6C to rise; the rising and falling of the lifting shaft will cause the paper-pressing strip 5C to rise and fall.
[0088] When the left or right flip cup clamp flips back (flips downward, away from the mold), it presses down against the descending transmission part 7C, causing the descending transmission part to descend, which in turn causes the lifting shaft 6C to descend. The lifting shaft then drives the pressure strip to descend. When the flip cup clamp closes and flips (flips upward, towards the mold), the lifting shaft rises under the reset of the rising reset device. The rising and falling of the lifting shaft drives the rising and falling of the pressure strip. When the pressure strip rises, it presses against the lower side of the mold, holding the paper down so that the flip cup clamp can finally close to fit the mold for forming. The descent of the pressure strip is driven by the corresponding flip cup clamp, and the rise is driven by the rising reset device. No additional power source is required, resulting in a compact structure, higher mechanical linkage efficiency, and stable operation. The descending transmission part 7C is located below the flip cup clamp. Preferably, the flip cup clamp is connected to a pressure roller 44C, which is driven by the descending transmission part for smoother transmission. The pressure roller 44C can be set on a corresponding connecting shaft, and the connecting shaft on the flip cup clamp is connected to the second joint bearing.
[0089] The descent transmission unit 7C is equipped with a roller assembly 11C, which rolls against the vertical surface of the first support frame 1C. The roller assembly 11C maintains its rolling motion against the vertical surface, ensuring stable lifting and lowering of the descent transmission unit and the lifting shaft, resulting in a compact structure. To avoid the problem of the lifting shaft rotating, two sets of roller assemblies 11C are installed on one side of the vertical surface for greater stability.
[0090] The first support frame 1C includes a support plate 12C, a mounting shaft 2C mounted on the support plate 12C, and a guide hole 13C on the first support frame. The lifting shaft is disposed within the guide hole 13C, which can be a guide sleeve to ensure stable lifting and lowering of the lifting shaft. The guide hole is located on the support plate 12C. The side of the support plate can serve as the facade of the first support frame. The support plate 12C is connected to a transverse partition 14C to form the first support frame 1C. The transverse partition also has guide holes for the mounting shaft.
[0091] The pressure strip is connected to the third mounting base 15C, which has a clearance channel 16C. The third mounting base 15C is connected to the lifting shaft 6C, and the mounting shaft 2C is located within the clearance channel 16C. The lifting shaft drives the third mounting base 15C to rise and fall without interfering with the mounting shaft, resulting in a reasonable and compact structural layout.
[0092] The descending transmission unit 7C includes a locking block 17C, which has a locking hole 18C and a locking groove 19C. The locking hole and the locking groove communicate with each other. The locking block is equipped with a locking fastener 20C (such as a fastening bolt). The lifting shaft 6C is connected within the locking hole 18C. By adjusting the locking fastener, the locking groove and locking hole can be tightened or loosened, allowing adjustment of the relative vertical position of the locking block and the lifting shaft. The relative vertical position of the descending transmission unit 7C and the lifting shaft 6C will also be adjusted, allowing adjustment of the starting position of the paper pressing strip and the engagement position with the right-flipping cup clamp. The descending transmission unit 7C is equipped with an adjusting bolt 21C. By adjusting the position and height of the adjusting bolt 21C, the engagement position with the flipping cup clamp can be further adjusted. The adjusting bolt is also equipped with a locking nut 22C, which can be locked after the adjusting bolt is rotated to adjust the height to prevent loosening. During operation, the pressure strip first rises to press down on the mold, then flips the cup clamp to continue flipping and finally closes to press down on the mold. After this part of the forming is completed, the flipped cup clamp flips back first, and then drives the pressure strip to descend.
[0093] In this configuration, the rising reset device 8C includes a reset spring 23C, which is sleeved on the lifting shaft 6C and engages with the descending transmission part 7C. The reset spring releases its elastic force to return the descending transmission part to its rising position. Using a reset spring to reset the lifting shaft facilitates installation and provides a buffer when the pressure strip contacts the mold, preventing damage to parts. Specifically, the rising reset device 8C acts on the descending transmission part; when the descending transmission part descends under the action of the flipping cup clamp, the reset spring deforms and stores energy (compression); when the flipping cup clamp flips upward, the reset spring releases its elastic force to return the descending transmission part to its rising position.
[0094] Referring to the attached drawings, the cup dispensing assembly 14 has a cup dispensing mechanism, which includes a second support frame 1D. A bent tube 2D is mounted on the second support frame 1D, through which the finished paper container passes. A second input wheel 3D and a rotating positioning disk 4D are connected to the bent tube 2D. The inlet of the bent tube is coaxially aligned with the second input wheel and the rotating positioning disk (i.e., on the same axis). The second input wheel is connected to a rotary transmission device, which drives the second input wheel 3D to rotate, causing the bent tube to rotate. The bent tube, the second input wheel, and the rotating positioning disk rotate synchronously. Preferably, the inlet of the bent tube 2D is horizontally aligned with the axis of the coaxial alignment of the second input wheel 3D and the rotating positioning disk 4D, making assembly easier and operation smoother.
[0095] The outlet of the bend 2D is equipped with a first receiving port 6D and a second receiving port 7D. The rotation of the bend allows its outlet to switch between the first and second receiving ports. One of the first and second receiving ports is used to receive qualified products, and the other is used to receive unqualified products.
[0096] The second support frame 1D is equipped with a positioning roller 5D on one side. The rotating positioning disk 4D and the positioning roller 5D cooperate for support and positioning. The positioning roller 5D supports and positions the rotating positioning disk 4D. The structure is reasonable and the rotation is more stable. The bend 2D on the second support frame 1D is only supported and positioned by the positioning roller 5D and the rotating positioning disk 4D. It is not necessary to use a large bearing sleeve on the outside of the bend for support, which reduces the cost.
[0097] Preferably, the rotary transmission device includes a servo motor 8D, which is connected to a second output wheel 9D. The servo motor is equipped with a reduction gear 81D (such as a reduction gearbox) connected to the second output wheel 9D. The second output wheel 9D is connected to a second input wheel 3D. The second output wheel and the second input wheel use pulleys, sprockets, gears, etc., and the corresponding transmission uses belt drive, chain drive, or gear meshing. In the figure, pulley and belt drive are used for connection.
[0098] The servo motor drive offers faster speed, quicker response, and more precise, controllable and adjustable rotation angle, meeting the needs of different angle settings for the first and second receiving ports. For example, the bent pipe rotates 180 degrees or 90 degrees to switch between the first and second receiving ports.
[0099] The second support frame 1D has a support plate 16D with holes for the bent pipe to pass through. The second support frame 1D also has a base plate 17D for connection to the support plate 16D. A first receiving port 6D and a second receiving port 7D are located on the base plate 17D. Positioning rollers 5D are located on the front side of the support plate 16D of the second support frame. The front side of the second support frame 1D is connected (via connecting rods or connecting plates) to a cup-discharging air duct 20D. The cup-discharging air duct is existing technology and is connected to the inlet of the bent pipe 2D.
[0100] At least three positioning rollers 5D are arranged around the rotating positioning disk 4D, which cooperate to support and position the rotating positioning disk 4D. Four positioning rollers 5D are shown in the figure. The positioning rollers 5D are sleeved on the eccentric shaft 51D, which is mounted on the second support frame 1D. The positioning rollers 5D mounted on the eccentric shaft 51D facilitate assembly with the rotating positioning disk. Rotating the eccentric shaft adjusts the rotation center of the positioning rollers, and the interaction of the positioning rollers adjusts the rotation center of the rotating positioning disk, ensuring that the edge of the rotating positioning disk mates with the positioning rollers (especially when there is an annular groove). The eccentric shaft 51D uses eccentric bolts or eccentric screws, and its shaft has an eccentric part for mounting the positioning rollers.
[0101] Preferably, a support roller 10D (such as a bearing) is provided on the other side of the second support frame 1D. The support roller 10D is arranged around the bend 2D, which can further support the rotation of the bend 2D and make the rotation more stable. In the figure, the support roller 10D is on the rear side of the support plate 16D of the second support frame 1D. Preferably, the support roller 10D is connected to the support 11D, and the support 11D is connected to the second support frame 1D. The support 11D has a radially elongated hole 12D, and a locking fastener (such as a locking bolt or screw) is connected between the radially elongated hole and the second support frame 1D. The relative radial position of the support roller on the support is adjusted so that it can cooperate to support the bend. A sliding groove is also provided on the second support frame for the corresponding support to be assembled, and the radial adjustment position of the support is stable. In the figure, at least three (such as four) support rollers are arranged, and the support rollers are evenly distributed.
[0102] Preferably, the positioning roller 5D has an annular groove (for example, a V-shaped groove arranged in a ring), and the edge of the rotating positioning disk 4D matches the annular groove, with the edge embedded in the annular groove for greater stability.
[0103] The bend 2D has a straight section 13D and a bent section 14D or a folded section. The second input wheel 3D and the rotating positioning disk 4D are connected to the straight section 13D of the bend 2D. Alternatively, the bend 2D is externally connected to a mounting sleeve 15D, as shown in the attached figure. The second input wheel 3D and the rotating positioning disk 4D are connected to the mounting sleeve 15D. The bend 2D is made of a lighter material (such as PP or PE), making it lighter and faster in rotation. The mounting sleeve 15D cooperates with the support rollers 10D around the bend 2D.
[0104] The bottom roll assembly 8 and the pre-roll assembly 11 each adopt the edge roll assembly.
[0105] The edge-curling assembly includes an edge-curling movable shaft 1E, which is arranged laterally. An edge-curling device 2E is located at the front of the edge-curling movable shaft. The edge-curling device 2E is used for edge-curling. The edge-curling device 2E is either a mouth edge-curling device or a bottom edge-curling device. The corresponding edge-curling mold (mouth edge mold or bottom edge mold) is installed at the front of the edge-curling movable shaft. The edge-curling movable shaft 1E drives the edge-curling device 2E to move synchronously laterally and reciprocally for edge-curling the bottom and mouth edges of the paper tube. Some hemming requires the hemming die to rotate. The first and second final rolling assemblies use a structure where the hemming die does not rotate. If rotation of the hemming die is required, a hemming drive wheel 3E is connected to the hemming movable shaft. A first bearing 4E is installed between the hemming drive wheel 3E and the hemming movable shaft 1E, supporting the rotation of the hemming drive wheel on the hemming movable shaft. The hemming drive wheel is connected to a drive device 5E (such as a motor, drive belt, and output wheel) to drive its rotation. Connecting the hemming die of the hemming device to the hemming drive wheel allows it to rotate. The hemming drive wheel moves laterally back and forth with the hemming movable shaft, and the rotation of the hemming die cooperates with the hemming forming. See also... Figure 26The edge-rolling die of the edge-rolling device 2E does not need to rotate. The edge-rolling die is fixedly connected to the edge-rolling movable shaft. The corresponding edge-rolling assembly can also serve as the first final roll assembly and the second final roll assembly.
[0106] To ensure more stable operation of the hemming shaft, the hemming shaft 1E is laterally mounted on the cover 6E. A transparent panel 23E can be installed on the cover to observe the internal transmission structure and lubrication circuit. The cover 6E has a front support 7E and a rear support 8E. The front support has a front mounting hole, and the rear support has a rear mounting hole. Second bearings 9E (such as copper sleeves) are installed between the hemming shaft and the front and rear mounting holes, respectively. The hemming shaft 1E is installed within these second bearings, which support its lateral reciprocating movement. The second bearings 9E provide support at two points (front and rear positions) for the hemming shaft 1E's lateral reciprocating movement. This two-point support on the cover provides better support and greater stability. The cover can be a single piece.
[0107] The cover 6E is connected to the base 10E, and the base 10E is provided with a second rotary drive shaft 11E, which is connected to the hemming movable shaft 1E. The rotation of the second rotary drive shaft 11E drives the hemming movable shaft 1E to move laterally back and forth.
[0108] A second eccentric wheel transmission mechanism is provided on the second rotary drive shaft 11E. The second eccentric wheel transmission mechanism includes a second eccentric wheel 12E connected to the second rotary drive shaft, and the second eccentric wheel 12E is operatively connected to the hemming movable shaft 1E. The second rotary drive shaft is driven by the second eccentric wheel transmission mechanism to move the hemming movable shaft laterally. As an optimization, a second sleeve 13E is operatively connected to the second eccentric wheel 12E. The sleeve hole of the second sleeve 13E is operatively connected to the second eccentric wheel 12E. When the second eccentric wheel 12E rotates with the second rotary drive shaft 11E, it will cause the second sleeve 13E to oscillate. The rear end of the sleeve 13E is a second connecting part 15E. The left and right sides of the second connecting part 15E are respectively provided with tie rod holes, and a second tie rod 16E is provided in the tie rod holes. The second pull rod is equipped with a second spring 17E and a second limiting part 18E. The second limiting part and the second spring are respectively located on the front and rear sides of the pull rod hole. The second spring and the second limiting part cooperate to keep the second pull rod stably connected in the corresponding pull rod hole of the second connecting part. When the second sleeve 13E is driven to swing, the second pull rod can move slightly relative to the position of the pull rod hole. In addition, when the curling movable shaft moves forward and cooperates with the mold, the second spring 17E can play a buffering role, and also buffers accidental collisions. The pressure of the second spring also plays a working holding role, so that the curling mold can curl under the action of the elastic force, and the curling working time and pressure are maintained, resulting in better forming effect. The second spring is pre-tightened on the second pull rod by the pre-tightening nut 19E. The rear part of the curling movable shaft is connected to the second transmission block 20E. In the figure, the second transmission block 20E is clamped on the curling movable shaft and locked by fasteners. The second transmission block 20E is hinged to the second connecting seat 21E below. The left and right sides of the second connecting seat are respectively connected to the second pull rods 16E on the left and right sides of the second connecting part. The tie rods in the tie rod holes on the left and right sides of the second connecting part are respectively connected to the left and right sides of the connecting seat. When the second eccentric wheel 12E drives the second sleeve to swing, the second tie rod 16E drives the second connecting seat to swing and move back and forth, the second connecting seat 21E drives the second transmission block 20E to move forward and backward, and the rolled edge movable shaft connected to the second transmission block will also move forward and backward laterally. Its second eccentric wheel transmission mechanism has a reasonable structure, stable operation, and can meet high-speed requirements. The second eccentric wheel and the second rotary drive vertical shaft are either an integral structure or a separate structure; preferably, they are separate structures. The second eccentric wheel 12E is mounted on the second rotary drive vertical shaft 11E. The second eccentric wheel and the second rotary drive vertical shaft are connected and installed using a separate structure and fasteners, which is more compact and small than the integral structure. The second eccentric wheel 12E adopts a disc-type eccentric wheel and utilizes the outer contour for transmission; preferably, the second eccentric wheel adopts an eccentric wheel with an eccentric column 22E, and a third bearing 24E (for rotational support) is provided between the eccentric column of the second eccentric wheel and the sleeve hole of the sleeve seat, so that the transmission is smoother and more stable.
[0109] The second connecting seat 21E has a hinge hole, and a fourth bearing 25E (such as a double-row angular contact ball bearing) is located between the second transmission block 20E and the hinge hole, making the transmission fit between the second connecting seat and the second transmission block smoother and more stable. A swing clearance is left between the pull rod hole and the second pull rod, allowing the pull rod to swing within the pull rod hole. The second connecting seat has through holes that connect to the second pull rod. Locking nuts 26E are located on both sides of the through holes and on the second pull rod. Adjusting the position of the locking nuts 26E on both sides of the through holes changes the relative position of the second pull rod and the second connecting seat, thereby adjusting the starting position of the forward and backward movement of the hemming movable shaft.
[0110] Preferably, a guide wheel 27E is connected to the second transmission block 20E, the guide wheel 27E is configured in a guide groove 28E, the guide groove 28E is set on a guide seat 29E, and the guide seat is connected to the seat cover 6E. The structural layout is reasonable and compact, and the guide wheel corresponds to the second connecting seat 21E located below the second transmission block, resulting in better balance.
[0111] The rear side of the seat cover is equipped with a rear cover 30E, and the front side of the seat cover is equipped with a front cover 31E. The front cover 31E has a movable through hole, and the curling movable shaft is connected in the movable through hole. The rear cover and the front cover cover cover the internal structure of the curling assembly to prevent the lubricating oil from splashing or leaking. A sealing ring is installed in the movable through hole of the front cover, which is located between the front cover and the curling movable shaft, to seal when the curling movable shaft moves in the movable through hole. A seal is also provided between the rear cover and the seat cover to ensure a tight seal.
[0112] A fifth bearing 32E is provided between the second rotary drive shaft 11E and the base 10E, supporting the second rotary drive shaft to rotate on the base. A sprocket connected to the lower part of the second rotary drive shaft serves as a bottom winding drive wheel device 81 or a pre-winding drive wheel device 111, inputting power to the second rotary drive shaft and driving it to rotate.
[0113] If a crimping drive wheel is provided, a step is provided at the front of the crimping movable shaft for the installation of the first bearing 4E. The step is equipped with a retaining ring for axially limiting the first bearing. The crimping drive wheel and the crimping die or crimping bottom die clamp the first bearing, which is convenient to install and has a reasonable combination.
[0114] Referring to the attached drawings, the rolling assembly 9 includes a rolling mechanism, which includes a support shell 15F. A rolling shaft 16F is provided on the support shell 15F. The rolling shaft 16F is rotatable and axially movable. A rolling sleeve device 30F is also provided at the front of the support shell 15F. The rolling sleeve device 30F includes a rolling sleeve 38F and a template 44F. The template 44F is connected to the front end of the rolling sleeve 38F. A wedge block 37F is provided at the front end of the rolling shaft. A movable block device 31F is connected to the front end of the rolling shaft. The movable block device includes an inner movable block 32F and an outer movable block 33F. The inner movable block 32F has a wedge hole 36F that mates with the wedge block portion. When the rolling shaft 16F moves axially, the wedge block portion and the wedge hole mate to make the inner movable block move eccentrically (to one side). When the rolling shaft rotates, the wedge block portion and the wedge hole mate to make the inner movable block rotate. When the rolling shaft rotates and moves axially, it can make the inner movable block rotate and move eccentrically. A sixth bearing 35F connects the inner movable block and the outer movable block. The eccentric movement of the inner movable block can make the outer movable block move eccentrically. The sixth bearing 35F makes the inner movable block rotate within the outer movable block. The outer movable block does not rotate on its own axis except for its revolution. The outer movable block 33F is located inside the rolling sleeve 38F. A support shaft 45F is also provided on the outer movable block 33F. The support shaft 45F moves with the outer movable block (eccentric movement and revolution). A seventh bearing 46F is provided on the support shaft, and a rolling wheel 47F is provided on the seventh bearing 46F. The rolling wheel 47F is supported by the seventh bearing 46F and rolls on the support shaft. The rolling wheel 47F is located in the inner hole of the template 44F. The rolling wheel 47F moves eccentrically and revolves with the support shaft on the outer movable block, and the rolling wheel engages with the inner hole of the template for rolling. The rotation and axial movement of the rolling shaft, through the engagement of the wedge block and the wedge hole, can drive the inner movable block to rotate and move eccentrically, thereby enabling the outer movable block to move eccentrically and revolve within the rolling sleeve. Ultimately, this causes the rolling wheel to move eccentrically and revolve with the support shaft on the outer movable block, and the rolling wheel engages with the inner hole of the template for rolling. The movable block device allows the seventh bearing to be a smaller bearing, resulting in a compact structure; the sixth bearing in the movable block device is a larger bearing, which increases the service life of the sixth bearing; the sixth and seventh bearings are subjected to unidirectional forces, and will not be subjected to bidirectional forces.
[0115] The rolling sleeve 38F is located in the front support hole of the support shell 15F. An eighth bearing 50F is provided between the front support hole and the rolling sleeve. The eighth bearing 50F (such as a copper sleeve) supports the rolling sleeve 38F to slide axially within the front support hole, providing support for front-to-back adjustment and axial buffering. The rolling sleeve is connected to a guide rod 51F. The support shell 15F has a guide sleeve or guide hole that connects to the guide rod. The guide rod guides the rolling sleeve 38F through its cooperation with the guide sleeve or guide hole, ensuring stable axial sliding and preventing rotation. Furthermore, the guide rod 51F is equipped with a tension return spring 52F, located between the rolling sleeve and the support shell. The tension return spring provides axial buffering for the rolling sleeve on the support shell. A locking nut 53F is also provided at the end of the guide rod, limiting its position on one side of the guide sleeve or guide hole. The position of the locking nut on the guide rod allows adjustment of the rolling sleeve's front-to-back axial position on the support shell, meeting different specification requirements.
[0116] The outer movable block 33F is provided with a disc part 34F, and the rolling sleeve 38F is provided with an annular groove 39F. The circumferential edge of the disc part is surrounded by the annular groove 39F. The circumferential edge of the disc part matches in the annular groove, preventing the disc part 34F from detaching from the annular groove 39F and forming a leakage point. The annular groove and the disc part slide in fit, and the circumferential edge of the disc part is always located in the annular groove and maintains a sliding fit, making the operation more stable.
[0117] A rotating drive wheel 54F is connected to the rolling shaft 16F. The rotating drive wheel 54F is located outside the support shell 15F. When the rotating drive wheel 54F rotates, it drives the rolling shaft to rotate. The rotating drive wheel is driven by a motor 55F via a belt. The support shell 15F is mounted on the first moving plate 1F. The rolling shaft 16F is connected to the second moving plate 2F. The first moving plate 1F is connected to the first transverse track, which guides its movement. The second moving plate 2F is connected to the second transverse track, which guides its movement. A third rotary drive shaft 3F is mounted on the base 6F. A forward cam 7F and a backward cam 8F are connected to the third rotary drive shaft 3F. The third rotary drive shaft is vertical. When the third rotary drive shaft 3F rotates, it drives the forward cam 7F and the backward cam 8F to rotate. For example, both the first and second transverse tracks are linear guides (such as V-shaped), and wheels on the corresponding moving plates move along the linear guides.
[0118] The first moving plate 1F is provided with a second front roller 9F, which is located in front of the forward cam 7F. The forward cam 7F and the second front roller 9F are in a top-drive engagement (i.e., a push-and-pull drive). The first moving plate 1F is also in a drive engagement with a first spring device 10F, which is connected between the first moving plate 1F and the base 6F. The second moving plate 2F is provided with a second rear roller 13F, which is located behind the retracting cam 8F. The retracting cam 8F and the second rear roller 13F are in a top-drive engagement (i.e., a push-and-pull drive). The second moving plate is also in a drive engagement with a second spring device 14F, which is connected between the second moving plate and the first moving plate. When the forward cam pushes the second front roller forward (to the right in the diagram), the working curve of the forward cam gradually bulges out. The second front roller moves forward synchronously with the first moving plate. The first spring device can buffer and store force (for example, if the first spring device is a compression spring, it will compress). After the first moving plate moves forward to its position, the working curve of the forward cam maintains the position of the second front roller. The second spring device deforms when the first moving plate moves forward, driving the second moving plate forward (if the second spring device is a compression spring, it will compress and deform to push). The working curve of the backward cam contracts inward to make way for the second rear roller and the second moving plate to move forward. After the first moving plate moves forward to its position, the second spring device continues to release elastic force to the second moving plate to move forward until it is in place (it can be used for rolling work to maintain extension and buffer). Then the working curve of the backward cam bulges out and pushes the second rear roller to move backward (to the left in the diagram). The second moving plate moves backward synchronously with the second rear roller. Then the working curve of the forward cam makes way for the second front roller to move backward. The second moving plate moves backward synchronously with the second rear roller. The second spring device can act on the first moving plate to move backward, and the first spring device will also act on the first moving plate to move backward until it moves backward to its position.
[0119] The forward and backward cams on the third rotary drive vertical shaft 3F cooperate with the first and second spring devices to drive the first and second moving plates to move forward and backward. The transmission structure is more reasonable and compact, with higher operational stability, meeting the requirements for further speed increase. The first moving plate is used to install the support shell of the rolling assembly. The support shell will be used to install the rolling sleeve device. The rolling shaft is set to rotate and move axially on the support shell. The second moving plate can be used to drive the rolling shaft forward and backward. With the cooperation of the second spring device, the rolling operation can be extended and buffered, and overload collision damage can be avoided.
[0120] The first spring device 10F includes a first spring, a first air cylinder, or a first hydraulic cylinder, and the second spring device 14F includes a second spring, a second air cylinder, or a second hydraulic cylinder. In the figure, the first spring device uses a first spring (e.g., a compression spring), and the second spring device uses a second spring (e.g., a compression spring). Corresponding spring mounting seats are provided for spring connection and installation.
[0121] The first transverse track is set on the base 6F of the rolling assembly, and the second transverse track is set on the first moving plate 1F. The first moving plate has a notch, and the second moving plate 2F is set on the notch; the layout is reasonable and the structure is more compact.
[0122] As a priority, the forward cam and the backward cam are two cams on a conjugate cam, forming a transmission relationship between the conjugate cam and the second front roller and the second rear roller, which is more stable, meets the needs of high speed, and has a longer service life.
[0123] A bearing 17F is provided between the third rotary drive shaft 3F and the base 6F. The third rotary drive shaft 3F is supported on the base by the bearing 17F and rotates vertically. The lower part of the third rotary drive shaft is connected to a rolling transmission wheel device 91, which is located below the lower port of the base. The rolling transmission wheel device 91 inputs power to the third rotary drive shaft, driving it to rotate. The forward cam and the backward cam are located below the first and second moving plates.
[0124] A transmission sleeve 21F is driven to the rolling shaft 16F. The transmission sleeve 21F has a circumferentially arranged annular groove 22F. When the rolling shaft 16F is driven to rotate, the transmission sleeve 21F and the annular groove 22F will rotate synchronously. A transmission seat 20F is provided on the second movable plate. The second spring device is driven to cooperate with the transmission seat. The transmission seat 20F is provided with at least three rollers 23F. The rollers 23F are arranged in the annular groove 22F, and the three rollers form a right angle or acute angle triangle with each other. Roller 23F rolls on transmission seat 20F. Roller shaft 24F is provided on transmission seat 20F for mounting roller 23F. Roller 23F is configured in an annular groove 22F. When transmission seat 20F is driven forward and backward (transmission seat is driven to move forward and backward by second moving plate), the roller and the annular groove of transmission sleeve drive the rolling shaft to move forward and backward (axial movement), and the rolling shaft can rotate. The three rollers form a right angle or acute angle triangle with each other, so that the rolling shaft is surrounded by at least three rollers, which is more stable and avoids shaking.
[0125] A front rotation and axial sliding support device 56F is provided between the rolling shaft 16F and the rolling sleeve seat 38F to support the rotation and axial sliding of the rolling shaft; a rear rotation and axial sliding support device 57F is provided between the rolling shaft and the rear support hole of the support shell to support the rotation and axial sliding of the rolling shaft. The front rotation and axial sliding support device includes a ninth bearing and a first guide sleeve (such as a copper sleeve). The rolling shaft is located inside the first guide sleeve, and the ninth bearing is positioned between the first guide sleeve and the rolling sleeve seat. The rolling shaft is supported and moves axially within the first guide sleeve, and the first guide sleeve rotates on the rolling sleeve seat supported by the ninth bearing. An axial sliding key is provided between the first guide sleeve and the rolling shaft, allowing the rolling shaft and the first guide sleeve to slide relative to each other axially while maintaining synchronous rotation, thus improving stability. The rear rotation and axial sliding support device includes a mounting sleeve, a support sleeve, a tenth bearing, and a second guide sleeve (such as a copper sleeve). The mounting sleeve is connected to the rear support hole. The second guide sleeve is located between the mounting sleeve and the support sleeve. The tenth bearing is positioned between the support sleeve and the rolling shaft, supporting the rolling shaft to rotate on the support sleeve. The support sleeve is axially slidable by the second guide sleeve, facilitating the installation of lubrication channels. A spacer is provided inside the support sleeve to facilitate the installation of the tenth bearings on both sides. A sealing ring is provided between the mounting sleeve and the support sleeve, and the sealing ring is positioned within the mounting groove of the mounting sleeve.
[0126] The rolling sleeve 38F is provided with an inlet channel 40F, which communicates with an annular groove. The front side of the annular groove has a sealing ring mounting groove, and a sealing ring 41F is installed in the sealing ring mounting groove. The front or rear side of the annular groove has a grooved ring.
