Description

Technical Field

[0001] This application relates to the technical field of tissue paper processing, and in particular to an automated tissue paper packaging device. Background Technology

[0002] In the production process of tissue paper products, packaging multi-layered wet wipes into packaging bags is one of the main steps. Related technologies typically employ equipment for packaging wet wipes, including a tissue paper conveying mechanism, a packaging bag supply mechanism, a sealing mechanism, a bagging structure, and a shearing mechanism. The multi-layered wet wipes are conveyed to the bagging mechanism via the tissue paper conveying mechanism. The packaging bag initially consists of a long strip of paper, wound onto a unwinding drum. The unwinding drum is driven to rotate by the packaging bag supply mechanism, causing the paper to unwind and be conveyed to the sealing mechanism. The sealing mechanism then heat-seals a pre-defined area of ​​the long strip of paper.

[0003] Then, the paper bag is punched and cut in a pre-set area by a shearing mechanism to form an independent packaging bag. One end of the packaging bag is open and the other end is sealed. Other components open the inside of the packaging bag and fit it onto the bagging mechanism. The open end of the packaging bag faces the tissue conveying mechanism, which feeds the tissue into the packaging bag. After further processing, the packaging bag is sent out by the discharge mechanism.

[0004] The problem with the related technology is that there are usually other auxiliary components between the shearing mechanism and the packaging bag supply mechanism. The packaging bag paper unwound from the packaging bag supply mechanism needs to be relatively long to reach the shearing mechanism for punching and cutting. The longer packaging bag paper is prone to deviation during this transmission process. When the shearing mechanism cuts the packaging bag paper, it will cause the cutting position and shape to not meet the requirements, thus affecting the quality of the finished product. Summary of the Invention

[0005] To improve the quality of finished products, this application provides an automated tissue packaging device.

[0006] The automated tissue packaging equipment provided in this application adopts the following technical solution:

[0007] An automated tissue packaging device includes a frame on which a tissue supply unit and a bag paper supply unit are mounted. A pre-processing unit, a bagging unit, and a post-processing unit are located between the tissue supply unit and the bag paper supply unit. The bag paper supply unit supplies elongated bag paper to the pre-processing unit. A positioning unit is provided along the bag paper supply path. The positioning unit includes a positioning roller mounted on the frame. The bag paper is fed forward through the positioning roller. A transverse groove is formed on the side of the positioning roller facing the bag paper. The positioning unit also includes two positioning side plates slidably mounted within the transverse groove. The distance between the two positioning side plates is equal to the width of the bag paper. A transverse drive assembly is provided on the positioning roller to drive the two positioning side plates to move synchronously and in the same direction.

[0008] By adopting the above technical solution, the coordinated arrangement of the tissue paper supply unit, bag paper supply unit, pre-processing unit, bagging unit, and post-processing unit enables automated packaging of tissue paper, achieving full-process assembly line operation with high processing efficiency. The alignment unit located on the bag paper supply path can correct the position of the bag paper in real time, preventing misalignment during subsequent processing and ensuring the final product quality.

[0009] Optionally, the alignment roller has a hollow chamber, the transverse groove is connected to the chamber, and a shaft is provided in the chamber, which is coaxially distributed with the alignment roller. The alignment side plate includes an inner ring plate and an outer ring plate that are integrally connected. The inner ring plate is slidably sleeved on the shaft, and the outer ring plate is slidably sleeved on the alignment roller.

[0010] By adopting the above technical solution, the two positioning side plates can limit the position of the bag paper passing through them. The inner ring plate is slidably connected to the shaft, and the outer ring plate is slidably connected to the positioning roller, so that the positioning side plates can slide along the extension direction of the transverse groove, thereby adjusting the position of the bag paper set between the two positioning side plates.

[0011] Optionally, the lateral drive assembly includes a drive ring connected to the alignment side plate. The drive ring is sleeved on a shaft. A helical groove is formed on the surface of the shaft corresponding to the drive ring. A transmission protrusion extending into the helical groove is formed on the side of the drive ring facing the shaft, so as to form a structure in which the transmission protrusion drives the drive ring to move laterally along the axial direction when the shaft rotates. One end of the shaft is connected to a first driver that drives the shaft to rotate.

[0012] By adopting the above technical solution, when the first driver drives the shaft to rotate, the matching position of the spiral groove and the transmission protrusion changes, and then the alignment side plate is moved laterally along the axis through the transmission protrusion and the drive ring, making the bag paper position adjustment convenient and the structure simple.

[0013] Optionally, the alignment unit further includes an inner clamping plate disposed in the transverse groove, and a radial drive assembly for driving the inner clamping plate to be pushed out and retracted radially along the alignment roller. The inner clamping plate is disposed between two alignment side plates and its two ends abut against each other. The radial drive assembly is mounted on the alignment side plates. The alignment unit also includes an outer clamping roller mounted on the outer periphery of the alignment side plates. The outer clamping roller is disposed in cooperation with the inner clamping plate.

[0014] By adopting the above technical solution, the inner clamping plate and the outer clamping roller are set together. The radial drive component drives the inner clamping plate to be pushed out from the transverse groove, so that the paper bag passing through the surface of the inner clamping plate is clamped between the inner clamping plate and the outer clamping roller. When the two alignment side plates move, they drive the clamped paper bag to move synchronously, which can ensure the alignment effect and accuracy.

[0015] Optionally, the frame is provided with a waist-shaped groove, and the alignment roller is slidably installed in the waist-shaped groove. The alignment unit also includes a tension drive assembly for driving the alignment roller to slide, which is used to adjust the tension of the bag paper passing through the alignment roller.

[0016] By adopting the above technical solution, when the tensioning drive assembly drives the positioning roller to move along the extension direction of the waist-shaped groove, it can control the tension of the bag paper during the feeding process. When it is necessary to adjust the position of the bag paper, the tensioning drive assembly drives the positioning roller to move to the inside of the bag paper that has passed through it, so that the bag paper is not loosened. After the bag paper is loosened, its position adjustment is more convenient.

[0017] Optionally, the inner ring plate protrudes outward from the side facing the inner clamping plate to form a housing. A through hole for the shaft to pass through is provided in the middle of the housing. The radial drive assembly includes a rotating ring plate rotatably installed in the housing. A transmission groove is provided on the surface of the rotating ring plate. The transmission groove is linear and one end is inclined away from the center of the rotating ring plate. A transmission rod is provided in the transmission groove. The transmission rod extends radially along the toothed ring. A limiting hole is provided in the part of the housing facing the transverse groove. One end of the transmission rod passes through the limiting hole and is connected to the inner clamping plate. The radial drive assembly also includes a transmission component for driving the rotating ring plate to rotate.

[0018] By adopting the above technical solution, when the rotating ring plate is driven to rotate by the transmission component, the position of the transmission rod in the transmission groove changes and is driven to slide along the extension direction of the limiting hole, thereby making the inner clamping plate closer to or further away from the outer clamping roller.

[0019] Optionally, the pre-processing unit includes a front-end sealing assembly and a primary shearing assembly mounted on the frame. The front-end sealing assembly is close to the coding assembly, and the primary shearing assembly is positioned on the path from the front-end sealing assembly to the bagging unit. The primary shearing assembly has a channel for conveying the bag, and two clamping assemblies are respectively provided at both ends of the channel for clamping the two ends of the bag during the shearing process.

[0020] By adopting the above technical solution, the paper bag is sequentially fed from the paper bag supply unit through the coding assembly, the front sealing assembly, and the primary shearing assembly. These components respectively perform coding at fixed positions on the paper bag, heat sealing, and shearing, ultimately forming a packaging bag that is open at one end and sealed at the other, for use in the subsequent bagging unit. The first and second clamping assemblies clamp both ends of the paper bag during the shearing process, preventing the paper bag from shifting position.

[0021] Optionally, the pressing assembly includes a support plate installed on the side of the primary shearing assembly near the bagging unit. The support plate has a through opening corresponding to the channel, and pressing grooves are formed on both sides of the through opening. A first pressing cylinder is installed on the support plate. The first pressing cylinder has an upwardly extending telescopic end, and the telescopic end is connected to a pressing plate. The pressing plate is configured to cooperate with the pressing grooves to press the two sides of the bag paper passing through the support plate.

[0022] By adopting the above technical solution, the first pressing component moves the pressing plate closer to or away from the support plate to achieve pressing or preventing loosening of one end of the bag paper.

[0023] Optionally, a traction component is also provided on the side of the primary shearing component near the front sealing component. The traction component is used to pull the bag paper toward the primary shearing component. The second pressing component is provided between the primary shearing component and the traction component. It includes an upper rubbing plate and a lower rubbing plate distributed vertically, and a second pressing cylinder connected to the upper rubbing plate. The second pressing cylinder is used to drive the upper rubbing plate to move closer to or away from the lower rubbing plate.

[0024] By adopting the above technical solution, the second pressing cylinder drives the upper rubbing plate to move closer to or away from the lower rubbing plate, so as to press or prevent loosening of the other end of the bag paper.

[0025] Optionally, a translation drive assembly is further provided between the primary shearing assembly and the traction assembly. The translation drive assembly has two drive ends, and the upper rubbing plate and the lower rubbing plate are respectively connected to the two drive ends. The translation drive assembly is used to drive the upper rubbing plate and the lower rubbing plate to move synchronously in opposite directions.

[0026] By adopting the above technical solution, the two driving ends of the translation drive assembly can drive the upper and lower rubbing plates to move in opposite directions respectively. During the movement, the upper and lower surfaces of the bag paper pressed between the upper and lower rubbing plates move accordingly, thereby performing a pre-opening action on the bag paper to facilitate the subsequent bagging unit to open the packaging bag.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By setting a positioning unit on the paper bag supply path, under the cooperation of the transverse drive component and the radial drive component, the radial drive component can bring the inner clamping plate closer to the outer clamping roller, so that the paper bag that was originally fed forward by the positioning roller is clamped between the inner clamping plate and the outer clamping roller. The transverse drive component drives the two positioning side plates to slide left and right in the transverse shift groove, thereby adjusting the local position of the paper bag laterally, so that when the position shifts during the paper bag supply process, it can be adjusted in time.

[0029] 2. Through the coordinated arrangement of clamping components one and two, during the first cutting action of the bag paper, clamping components one and two can simultaneously clamp and fix both ends of the bag paper, preventing the bag paper from shifting position when the punching blade cuts downwards. The translation drive component can cause the upper and lower rubbing plates to move in opposite directions simultaneously after the cutting is completed. The upper and lower surfaces of the bag paper, which are clamped and fixed between the upper and lower rubbing plates, are rubbed left and right by friction, thereby achieving pre-opening, so that the subsequent bagging unit can open the open end of the packaging bag.

Detailed Implementation

[0042] The following is in conjunction with the appendix Figure 1-11 This application will be described in further detail.

[0043] This application discloses an automated tissue packaging device. (Refer to...) Figure 1 An automated tissue packaging device includes a frame 1 and a tissue supply unit 2 and a bag supply unit 3 fixed on the frame 1, as well as a pre-processing unit 4 and a bagging unit 5 disposed between the tissue supply unit 2 and the bag supply unit 3, wherein the bag processing unit is disposed on the side closer to the bag supply unit 3, and the bagging unit 5 is disposed on the side closer to the tissue supply unit 2.

[0044] The tissue supply unit 2 has an input end and an output end, with the output end close to the bagging unit 5 to feed tissues to the bagging unit 5. The bag supply unit 3 is used to provide the bagging unit 5 with a separate packaging bag body that is open at one end and sealed at the other end. The bagging unit 5 is used to feed the tissues that have been fed to the vicinity into the bag body from the open end of the packaging bag body to complete the bagging.

[0045] Furthermore, a discharge unit 6 is also provided on the frame 1. A post-processing unit 7 is provided between the discharge unit 6 and the bagging unit 5. The packaging bag containing paper towels is processed into a finished product at the post-processing unit 7, and the finished product is sent out through the discharge unit 6.

[0046] Reference Figure 1 and Figure 2 The tissue supply unit 2 includes a storage conveyor belt group 21, a skip-packing assembly 22, and an intermittent conveyor belt group 23, which are sequentially distributed and connected end-to-end from one side of the frame 1 towards the bagging unit 5. The input end of the tissue supply unit 2 is located at the end of the storage conveyor belt group 21 away from the skip-packing assembly 22, and the output end is located at the end of the intermittent conveyor belt group away from the skip-packing assembly 22. Tissues are placed on the storage conveyor belt group 21 from the input end, move towards the skip-packing assembly 22 with the storage conveyor belt group, and then are fed into the intermittent conveyor belt group 23 through the skip-packing assembly 22. The intermittent conveyor belt group 23 is used to intermittently supply tissues to the output end. The specific structure and working principle of the storage conveyor belt group 21, the skip-packing assembly 22, and the intermittent conveyor belt group 23 are all prior art and will not be described in detail here.

[0047] During the process of the tissue paper supply unit 2 conveying tissue paper to the bagging unit 5, the bag paper supply unit 3 simultaneously provides the bagging unit 5 with a packaging bag that is open at one end and sealed at the other end through the pre-processing unit 4.

[0048] Reference Figure 1 and Figure 2The bag paper supply unit 3 includes an unwinding roller 31 mounted on the frame 1. An air shaft 32 passes through the middle of the unwinding roller 31. A roll of bag paper is wound on the air shaft 32. The roll can be connected to the air shaft 32 by inflating the air shaft 32. When the motor drives the unwinding roller 31 to rotate, the roll rotates with the unwinding roller 31, so that the bag paper is conveyed to the forward processing unit 4 at a certain speed. It can be understood that the bag paper conveyed to the forward processing unit 4 is long and thin.

[0049] Furthermore, a buffer assembly 8 and a pressing assembly 9 are provided on the path of the bag paper being conveyed from the bag paper supply unit 3 to the forward processing unit 4. The pressing assembly 9 is located between the unwinding roller 31 and the buffer assembly 8. The pressing assembly 9 includes an upper pressing plate 91 and a lower pressing plate 92 mounted on the frame 1 and distributed vertically opposite each other, a pressing cylinder 93 that drives the upper pressing plate 91 to move closer to or away from the lower pressing plate 92, and a pressing guide roller 94 that guides one end of the bag paper drawn from the unwinding roller 31 between the upper pressing plate 91 and the lower pressing plate 92.

[0050] The buffer assembly 8 includes two sets of buffer roller groups 81 arranged vertically. Each set of buffer roller groups 81 includes multiple buffer rollers spaced apart in the same row. The bag paper, drawn from the pressing assembly 9, is sequentially conveyed vertically and horizontally around each buffer roller to the forward processing unit 4. The buffer assembly 8 also includes an electric slide rail 82 that drives at least one set of buffer roller groups 81 to move vertically. When the electric slide rail 82 controls the two sets of buffer roller groups 81 to move closer to each other, the bag paper passing through the buffer assembly 8 gradually becomes loose. When the electric slide rail 82 controls the two sets of buffer roller groups 81 to move away from each other, the bag paper passing through the buffer assembly 8 is tightened.

[0051] The buffer assembly 8 and the pressing assembly 9 are configured together. The bag paper is continuously supplied to the forward processing unit 4. As the bag paper on the unwinding roller 31 gradually decreases, when the bag paper is about to run out, its rear end passes through the pressing assembly 9. The pressing cylinder 93 presses and fixes the rear end between the upper pressing plate 91 and the lower pressing plate 92. At the same time, the electric slide rail 82 controls the two sets of buffer rollers 81 to move closer to each other, so that the bag paper passing around each buffer roller gradually becomes loose, so that there is enough margin to supply to the next unit. Thus, the bag paper can still be continuously supplied to the next unit during the process of replacing the previous roll of bag paper, ensuring the continuous operation of the equipment.

[0052] Furthermore, refer to Figure 2A coding assembly 10 is also provided on the path of the bag paper led out from the buffer assembly 8 to the forward processing unit 4. The coding assembly 10 includes a coding plate 101, a coding printer 102 and a coding guide roller 103. The coding guide roller 103 is used to guide the bag paper led out from the buffer assembly 8 over the coding plate 101. The coding printer 102 is installed above the coding plate 101. When the bag paper passes over the coding plate 101, it can intermittently spray codes on the bag paper, so that when the forward processing unit 4 processes the bag paper into individual packaging bags, the codes can be located in the same position of each packaging bag.

[0053] Reference Figure 2 , Figure 3 and Figure 4 A positioning unit 11 is also provided on the path of the paper bag being conveyed from the paper bag supply unit 3 to the forward processing unit 4. The positioning unit 11 includes multiple positioning rollers 111 mounted on the frame 1. The multiple positioning rollers 111 are respectively positioned near the pressing assembly 9, the buffer assembly 8 and the coding assembly 10, and preferably positioned at the rear end of the paper bag after passing the pressing assembly 9, the buffer assembly 8 and the coding assembly 10. The paper bag led out from the pressing assembly 9 passes through the pressing assembly 9, the first positioning roller 111, the buffer assembly 8, the second positioning roller 111, the coding assembly 10 and the third positioning roller 111 in sequence before being conveyed to the forward processing unit 4.

[0054] A transverse groove 112 is formed on the side of the alignment roller 111 facing the bag paper. The transverse groove 112 extends along the axial direction of the alignment roller 111. The alignment unit 11 also includes two alignment side plates 113 slidably installed in the transverse groove 112. The two alignment side plates 113 are relatively distributed and are parallel to the end face of the alignment roller 111. The distance between the two alignment side plates 113 is equal to the width of the bag paper and less than the length of the transverse groove 112. The alignment unit 11 also includes a transverse drive assembly 115 that drives the two alignment side plates 113 to move synchronously and in the same direction. When the two alignment side plates 113 move in the transverse groove 112, the local transverse position of the bag paper is adjusted, thereby playing a role in correction and alignment.

[0055] Furthermore, the alignment side plate 113 includes an inner ring plate 1131 and an outer ring plate 1132 connected to each other. A cavity is formed inside the alignment roller 111, and a shaft 114 coaxially distributed with the alignment roller 111 is installed in the cavity. The inner ring plate 1131 is sleeved on the surface of the shaft 114 and can slide relative to the shaft 114, while the outer ring plate 1132 is sleeved on the surface of the alignment roller 111 and can slide relative to the alignment roller 111. The cavity is connected to the transverse shift groove 112, and the portion connecting the inner ring plate 1131 and the outer ring plate 1132 is disposed in the transverse shift groove 112.

[0056] Furthermore, the alignment unit 11 also includes an inner clamping plate 116 disposed between the two alignment side plates 113, and an outer clamping roller 117 mounted on the two alignment side plates 113, with the inner clamping plate 116 and the outer clamping roller 117 being distributed opposite to each other. The alignment unit 11 also includes a radial drive assembly 118 mounted on the alignment side plates 113, the drive end of which is connected to the inner clamping plate 116 and is capable of driving the inner clamping plate 116 to move toward or away from the outer clamping roller 117.

[0057] Preferably, both sides of the transverse shift groove 112 are formed into a stepped structure, and the outer side of the inner clamping plate 116 is configured to fit the transverse shift groove 112 so that the inner clamping plate 116 can be spliced ​​and fixed in the transverse shift groove 112. When the bag paper is normally supplied, the lower surface of the bag paper is in contact with the upper surface of the inner clamping plate 116. When the position of the bag paper is offset, the radial drive assembly 118 drives the inner clamping plate 116 to push outward, and the inner clamping plate 116 approaches the outer clamping roller 117, so that the bag paper is clamped between the inner clamping plate 116 and the outer clamping roller 117, thereby driving the transverse drive assembly 115 to move the two alignment side plates 113 laterally at the same time. The bag paper located between the two alignment side plates 113 moves laterally accordingly, thereby adjusting the position of the bag paper to achieve correction and alignment.

[0058] Specifically, the lateral drive assembly 115 includes drive rings 1151 respectively mounted on opposite sides of the two alignment side plates 113. The drive rings 1151 are slidably connected to the shaft 114. A helical groove is formed on the circumferential surface of the shaft 114 near the drive rings 1151. A transmission protrusion 1152 extending into the helical groove is provided on the side of the drive ring 1151 facing the shaft 114. When the shaft 114 rotates, the engagement position between the helical groove and the transmission protrusion 1152 changes. The shaft 114 forms the wall of the helical groove, driving the transmission protrusion 1152 to move, thereby causing the alignment side plates 113 to move via the drive rings 1151. The lateral drive assembly 115 also includes a first driver that drives the shaft 114 to rotate. The first driver can be a forward / reverse motor, etc.

[0059] It is important to note that, to prevent the alignment side plate 113 from rotating along with the shaft 114, a limiting structure is provided between the alignment side plate 113 and the alignment roller 111. Specifically, the limiting structure can be a key located on the inner wall of the alignment roller 111, extending axially along the roller. A keyway is formed on the outer periphery of the inner ring plate 1131 of the alignment side plate 113, and the key passes through this keyway, thereby constraining the rotation of the alignment side plate 113. This ensures that when the first driver drives the shaft 114 to rotate, the alignment side plate 113 can only move linearly along the axial direction of the shaft 114.

[0060] Reference Figure 5 and Figure 6A housing is formed protruding outward from the side of the inner ring plate 1131 facing the inner clamping plate 116. The radial drive assembly 118 is disposed inside the housing. A limiting hole is provided on the side of the housing facing the inner clamping plate 116. The limiting hole extends radially along the inner ring plate 1131. The radial drive assembly 118 includes a transmission rod 1181 passing through the limiting hole. The transmission rod 1181 can slide along the extension direction of the limiting hole. One end of the transmission rod 1181 is connected to the inner clamping plate 116, and the other end extends into the housing. A transmission assembly 1182 and a rotating ring plate 1183 for driving the transmission rod 1181 to slide are installed inside the housing. A transmission groove is provided on the rotating ring plate 1183. The end of the transmission rod 1181 extending into the housing is engaged in the transmission groove.

[0061] The transmission groove is a linear groove that is not parallel to any radial direction of the rotating ring plate 1183. One end of the groove is inclined away from the rotating ring plate 1183. When the rotating ring plate 1183 rotates, one end of the transmission rod 1181 moves in the transmission groove. The inclined shape of the transmission groove causes the transmission rod 1181 to slide along the extension direction of the limiting hole, thereby driving the inner clamping plate 116 to move closer to or away from the outer clamping roller 117.

[0062] Specifically, the transmission assembly 1182 can be composed of the following structural parts: A shaft sleeve is rotatably mounted inside the housing, and the shaft sleeve is sleeved on the shaft rod 114, with the two not affecting each other; that is, the rotation of either the shaft rod 114 or the shaft sleeve will not affect the other. The aforementioned rotating ring plate is fixed to the outer circumferential surface of the shaft sleeve and can rotate with the shaft sleeve. The transmission assembly 1182 includes a transmission gear set and a motor, wherein the driven wheel of the transmission gear set is fixed on the shaft sleeve. When the motor drives the transmission gear set to run, the driven wheel can drive the shaft sleeve to rotate, thereby causing the rotating ring plate 1183 to rotate. Of course, this embodiment only shows a specific technical solution of the transmission assembly 1182 that drives the rotating ring plate 1183 to rotate, and those skilled in the art can also make substitutions based on existing technology and common knowledge.

[0063] Furthermore, each positioning roller 111 on the frame 1 has a waist-shaped groove. The positioning roller 111 is slidably installed in the waist-shaped groove. The extension direction of the waist-shaped groove is parallel to the radial direction of the positioning roller 111, and the extension direction of the waist-shaped groove intersects the centerline of the portion of the bag paper passing through the positioning roller 111. A tensioning drive assembly (not shown in the figure) is also installed on the frame 1. The tensioning drive assembly is connected to the positioning roller 111 and is used to drive the positioning roller 111 to move within the waist-shaped groove. When the positioning roller 111 moves along the waist-shaped groove away from the bag paper passing through it, the bag paper in the feeding process can be relaxed. Then, the position of the bag paper is adjusted by the positioning unit 11. Compared with adjustment during tensioning, this is easier and less likely to cause the bag paper to be overstretched and deformed.

[0064] Reference Figure 7The pre-processing unit 4 includes a front-end sealing assembly 41 and a primary shearing assembly 42. The primary shearing assembly 42 is located near the bagging unit 5, and the front-end sealing assembly 41 is positioned between the primary shearing assembly 42 and the coding assembly 10. After the bag paper has been coated with the coding, it is first heat-sealed by the front-end sealing assembly 41. After heat-sealing, it is fed into the primary shearing assembly 42, which cuts the heat-sealed side of the bag paper, thus forming an independent packaging bag with one end open and the other end sealed. After cutting, the open end of the packaging bag faces the bagging unit 5.

[0065] The front-end sealing assembly 41 includes an upper front-end knife holder 411 and a lower front-end knife holder 412 distributed vertically, and a front-end sealing cylinder 413 that drives the upper front-end knife holder 411 or the lower front-end knife holder 412 to move closer or further apart. During the process of feeding the bag paper to the primary shearing assembly 42, the front-end sealing cylinder 413 intermittently extends and retracts, causing the upper front-end knife holder 411 and the lower front-end knife holder 412 to move closer and further apart. When they move closer, the bag paper undergoes a heat-sealing action; after heat-sealing, they move further apart. The specific heat-sealing structure of the upper front-end knife holder 411 and the lower front-end knife holder 412 is prior art and will not be described in detail here.

[0066] The primary shearing assembly 42 includes a shearing blade holder 421, a punching blade 422, and a shearing cylinder 423. The shearing blade holder 421 has a channel for the bag paper to be introduced into the shearing area from the front sealing assembly 41 and to be led out from the shearing area. The punching blade 422 is installed above the channel and its plane is perpendicular to the plane of the bag paper passing through the channel. The shearing cylinder 423 can drive the punching blade 422 to move up and down to punch the bag paper. It can be understood that the two ends of the punching blade 422 are set with arc-shaped structures, which can form rounded corners on both sides of the bag paper during the punching process.

[0067] Reference Figure 7 A traction component 12 is also provided on the side of the primary shearing component 42 near the front sealing unit. The traction component 12 is used to drive the bag paper forward after it has undergone one punching. The traction component 12 includes an active traction wheel 121 and a passive traction wheel 122 distributed vertically. The bag paper is conveyed between the active traction wheel 121 and the passive traction wheel 122, and the upper and lower surfaces of the bag paper are in full contact with the active traction wheel 121 and the passive traction wheel 122, respectively. When the active traction wheel 121 rotates in a specified direction, it can drive the bag paper forward through friction. The traction component 12 also includes a second driver that drives the active traction wheel 121 to rotate. The second driver can specifically be a belt drive component 1182.

[0068] A channel is formed on the shearing blade holder 43 for conveying the bag paper from the traction assembly 12 to the bagging unit 5. A clamping assembly 13 and a clamping assembly 2 15 are respectively provided at both ends of the channel. The clamping assemblies 13 and 2 15, working in tandem, can clamp and fix both ends of the bag paper during the shearing process, preventing the bag paper from shifting position during punching. Preferably, the clamping assembly 13 is located at the end of the channel closer to the bagging unit 5, and the clamping assembly 2 15 is located at the end of the channel closer to the traction assembly 12.

[0069] Reference Figure 8 The clamping assembly 13 includes a support plate 131 fixedly installed at one end of the channel. The support plate 131 has a clamping groove adapted to the width of the paper bag. When the traction assembly 12 drives the paper bag forward, the open end of the paper bag enters the clamping groove. The clamping assembly 13 also includes a first clamping cylinder 132 and a clamping plate 133 installed on the support plate 131. The clamping plate 133 is connected to the telescopic end of the first clamping cylinder 132. The support plate 131 and the clamping plate 133 are vertically distributed and parallel to each other. After the paper bag enters the clamping groove, the clamping plate 133 is located above the paper bag. By driving the clamping plate 133 downward through the first clamping cylinder 132, the end of the paper bag can be fixed between the clamping plate 133 and the support plate 131 for shearing. After the shearing is completed, the first clamping cylinder 132 drives the clamping plate 133 upward.

[0070] Furthermore, refer to Figure 9 A translation drive assembly 14 is disposed between the primary shearing assembly 42 and the traction assembly 12. The translation drive assembly 14 includes a timing belt and pulleys disposed at both ends of the timing belt, as well as a third driver connected to one of the pulleys. The timing belt extends along the width direction of the channel and includes a first part and a second part. When the third driver drives the pulley to rotate, the first part and the second part of the timing belt move synchronously in opposite directions. Sufficient space is reserved between the first part and the second part, which corresponds to the channel position, so that the bag paper drawn from the traction assembly 12 can enter the channel between the first part and the second part.

[0071] The first part is located above the second part, and mounting plates are installed at corresponding positions in both the first and second parts. The second clamping assembly 15 includes an upper rubbing plate 151 and a lower rubbing plate 152 distributed vertically, and a second clamping cylinder 153 connected to the upper rubbing plate 151. The second clamping cylinder 153 is mounted on the upper mounting plate, and the telescopic end of the second clamping cylinder 153 extends downward and is connected to the upper rubbing plate 151.

[0072] Using the above structure, when the paper bag passes between the first part and the second part, the upper rubbing plate 151 and the lower rubbing plate 152, and is then conveyed to the pressing assembly 13 through the channel, the first pressing cylinder 132 drives the pressing plate 133 to approach the support plate 131 to press one end of the paper bag tightly, and the second pressing cylinder 153 drives the upper rubbing plate 151 to approach the lower rubbing plate 152 to press the other end of the paper bag tightly. Then, the shearing cylinder 45 drives the punching cutter 422 to cut the paper bag.

[0073] After the cutting is completed, the first pressing cylinder 132 drives the pressing plate 133 away from the support plate 131, and the second pressing cylinder 153 maintains the pressing state on the bag paper. At this time, the third driver of the translation drive assembly 14 drives the pulley to rotate. The two mounting plates move with the first part and the second part. When the two mounting plates move, the upper rubbing plate 151 and the lower rubbing plate 152 move accordingly, thereby applying parallel and opposite rubbing forces to the bag paper pressed between the upper rubbing plate 151 and the lower rubbing plate 152. Under the action of the rubbing force, the packaging bag can be pre-opened to facilitate the subsequent bagging unit 5 to open the opening end of the bag paper.

[0074] Reference Figure 2 and Figure 10 The bagging unit 5 includes a horizontal transfer assembly 51 and an opening assembly 52 mounted on the horizontal transfer assembly 51, as well as a vertical transfer assembly 53 and a mouth-supporting assembly 54 mounted on the vertical transfer assembly 53. The opening assembly 52 has suction heads 521 disposed on the upper and lower sides of the packaging bag body. The two suction heads 521 can move closer or further apart. When the two suction heads 521 move closer, they can contact the upper and lower surfaces of the packaging bag body respectively and suction the upper and lower surfaces. After being suctioned, the two suction heads 521 move further apart, respectively driving the upper and lower surfaces of the packaging bag body to move further apart, thereby opening the open end of the packaging bag body. The horizontal transfer assembly 51 drives the opened packaging bag body to move from the primary shearing assembly 42 to the vertical transfer assembly 53.

[0075] The vertical transfer assembly 53 includes a turntable 531 that can rotate in a vertical plane. The support assembly 54 includes a bagging claw 541 disposed on the side of the turntable 531 facing the primary shearing assembly 42. The bagging claw 541 has two states: open and closed. When the horizontal transfer assembly 51 moves the open packaging bag towards the vertical transfer assembly 53, the bagging claw 541 is initially in a closed state, allowing the open end of the packaging bag to fit onto the closed bagging claw 541. Then, the bagging claw 541 returns to an open state, applying an internal support force from inside the packaging bag, thereby fixing the packaging bag onto the bagging claw 541. The turntable 531, which rotates in the vertical plane, has a first position and a second position. The first position corresponds to the position of the turntable 531 near the horizontal transfer assembly 51, and the second position corresponds to the position of the turntable 531 near the output end of the aforementioned tissue supply unit 2. The structures of the horizontal transfer assembly 51, the vertical transfer assembly 53, and the control structure for the opening and closing of the bagging claw 541 all employ existing technology and will not be described in detail here.

[0076] When the turntable 531 drives the bagging claw 541, which is fixed with the packaging bag, to rotate from the first position to the second position, the paper towels delivered to the output end of the paper towel supply unit 2 are loaded into the opened packaging bag.

[0077] Specifically, refer to Figure 10 A lifting unit 16 and a pushing unit 17 are provided before the tissue supply unit 2 and the bagging unit 5. The lifting unit 16 is connected to the output end of the tissue supply unit 2 and has a support surface parallel to the output end of the tissue supply unit 2. The tissues at the output end of the tissue supply unit 2 are further conveyed to the support surface of the lifting unit 16. The lifting unit 16 is configured to be vertically movable so that the support surface can be raised to the same horizontal plane as the second position of the turntable 531.

[0078] Both the lifting unit 16 and the pushing unit 17 are fixed to the side of the turntable 531 facing the tissue supply unit 2. A through-hole is provided on the turntable 531 at the second position. When the support surface of the lifting unit 16 is on the same plane as the second position of the turntable 531, the tissue placed on the support surface corresponds to the pushing hole on the turntable 531. The pushing unit 17 is used to apply a horizontal pushing force to the tissue from one side, so that the tissue can pass through the pushing hole and be put into the packaging bag.

[0079] Furthermore, a correction component 18 is provided on the support surface of the lifting unit 16 to correct the position of the tissue paper on the support surface, ensuring that the tissue paper corresponds to the push port. After pushing the tissue paper into the packaging bag, the pushing unit 17 can further push the tissue paper and the packaging bag towards the end away from the tissue paper supply unit 2. The lifting unit 16, the pushing unit 17, and the correction component 18 all adopt existing technology and will not be described in detail here.

[0080] The aforementioned post-processing unit 7 is positioned along the path of the pushing unit 17 that moves the packaging bag. The post-processing unit 7 includes a rear sealing unit 71 and a secondary cutting assembly 72. The rear sealing unit 71 heat-seals the open end of the packaging bag containing tissues, and the secondary cutting assembly 72 performs a secondary cutting action on the newly heat-sealed end of the packaging bag, ensuring that all four corners of both ends of the packaging bag are rounded with the same shape. Both the rear sealing unit 71 and the secondary cutting assembly 72 utilize existing technology and will not be described in detail here.

[0081] A support conveyor belt 19 is provided on the side of the post-processing unit 7 away from the bagging unit 5. The pushing unit 17 pushes the tissue and the packaging bag onto the support conveyor belt 19, so that most of the lower surface of the packaging bag is placed on the conveying surface of the support conveyor belt 19. A limit corner assembly 20 is provided at one end of the support conveyor belt 19 near the post-processing unit 7 to press and fix the part of the packaging bag placed on the conveying surface, so as to facilitate the back-end heat sealing and secondary punching.

[0082] Reference Figure 1 and Figure 11 The limiting corner insertion assembly 20 specifically includes a baffle 201 located at the front end of the packaging bag in the pushing direction, a limiting pressure plate 202 disposed above the packaging bag, and corner insertion plates 203 disposed on both sides of the packaging bag. Both the baffle 201 and the limiting pressure plate 202 can move vertically, and the two corner insertion plates 203 can move closer to or further away from each other. Using this structure, when the pushing unit 17 pushes the packaging bag containing tissues onto the support conveyor belt 19, the baffle 201 blocks the packaging bag, while the limiting pressure plate 202 moves downward to apply pressure to the upper surface of the packaging bag, fixing the packaging bag to the support conveyor belt 19. Then, the two corner insertion plates 203 move closer to each other, and the corner insertion plates 203 are configured as L-shaped structures, applying pressure to the packaging bag at their ends facing the packaging bag, causing the sides of the packaging bag to bend to form the required angles. Finally, the rear sealing unit 71 and the secondary shearing assembly 72 perform heat sealing and punching processing on the packaging bag. After processing, both the baffle 201 and the limiting pressure plate 202 move upward, while the corner plates 203 on both sides of the packaging bag move away from each other. The support conveyor belt 19 is then activated to transport the processed packaging bag to the discharge unit 6. The corresponding actions of the baffle 201, the limiting pressure plate 202, and the corner plates 203 can be driven by cylinders connected to each of them.

[0083] The end of the supporting conveyor belt 19 that is away from the post-processing unit 7 is connected to the discharge unit 6. The discharge unit 6 can be a flexible chain conveyor belt. The processed packaging bags fall onto the flexible chain conveyor belt and are transported outward with the flexible chain conveyor belt.

[0084] The implementation principle of an automated tissue packaging device according to an embodiment of this application is as follows: First, stacked tissues are placed on the tissue supply unit 2 and conveyed to the lifting unit 16. The paper bag is fed from the paper bag supply unit 3 and passes through the pressing component 9, the buffer component 8 and the coding component 10 in sequence into the pre-processing unit 4. Under the action of the front sealing unit and the first cutting component 42, the paper bag is processed into a separate packaging bag with one end open and the other end sealed. Before the first cutting, the pressing component 13 and the pressing component 2 15 press and fix the paper bag. After the cutting is completed, the fixing effect of the pressing component 13 on the open end of the packaging bag is released. At the same time, the translation drive component 14 drives the upper rubbing plate 151 and the lower rubbing plate 152 to move in opposite directions synchronously, so that the upper and lower surfaces of the paper bag are rubbed under the action of friction to perform the pre-opening action.

[0085] After the fixing effect of the open end of the packaging bag is released, the opening component 52 of the bag-covering unit 5 opens the open end, and the horizontal transfer component 51 drives the open packaging bag to move towards the turntable 531 through the opening component 52, and finally covers it on the support component 54. Then the motor drives the turntable 531 to rotate, so that the support component 54 with the packaging bag covered moves closer to the paper towel supply unit 2.

[0086] During the rotation of turntable 531, tissue supply unit 2 delivers tissues to lifting unit 16. Lifting unit 16 lifts the tissues upward to correspond with pushing unit 17. During this process, correction component 18 adjusts and positions the tissues. Then, pushing unit 17 pushes the tissues placed on lifting unit 16, so that the tissues are loaded into the open packaging bag through turntable 531, and further pushes the packaging bag through post-processing unit 7 and partially placed on support conveyor belt 19.

[0087] The baffle 201, the limiting pressure plate 202, and the corner plate 203 are all close to the packaging bag body placed on the support conveyor belt 19 and fix the position of the packaging bag body. Then, the rear sealing assembly and the secondary shearing assembly 72 of the post-processing unit 7 heat seal and shear the open end of the packaging bag body to generate the final product. After that, the baffle 201, the limiting pressure plate 202, and the corner plate 203 are all away from the final product. The support conveyor belt 19 drives the final product to be transported to the discharge unit 6 and sent out by the discharge unit 6.

[0088] During the process of feeding the paper bag from the paper bag supply unit 3 to the forward processing unit 4 via the pressing assembly 9, the buffer assembly 8, and the coding assembly 10, the positioning unit 11 can adjust the paper bag if its position is off. When adjusting the position of the paper bag, the tension drive assembly first drives the positioning roller 111 to move, so that the paper bag passing through the positioning roller 111 has a reduced tension. At the same time, the radial drive assembly 118 drives the inner clamping plate 116 to push out, so that the paper bag with reduced tension is clamped between the inner clamping plate 116 and the outer clamping roller 117. Then, the lateral drive assembly 115 drives the positioning side plate 113 to move laterally. When the positioning side plate 113 moves, the paper bag that is clamped and fixed moves accordingly, thereby realizing the adjustment of the position of the paper bag.

[0089] After adjustment, the tension drive assembly drives the alignment roller 111 to reset, and the radial drive assembly 118 drives the inner clamping plate 116 to retract, so that the bag paper re-contacts the surface of the alignment roller 111 and continues to be supplied forward through the alignment roller 111.

[0090] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
