Abstract

The present invention relates to the field of packaging machinery, and particularly relates to a linear filling device. It includes a conveying component, a film cutting component, and a handling and boxing component. In the film cutting component, the first hob longitudinally cuts between the connected cups, and the second hob makes longitudinal indentations between the single cups. When the template stops conveying, the third hob is driven by a driving cylinder to move linearly in the transverse direction to transversely cut between the connected cups, and the cutter is driven by a lifting cylinder I to descend to make transverse indentations between the single cups. In the handling and boxing component, through the adjustment of the transverse pitch-changing component and the longitudinal pitch-changing component, the transverse pitch and the longitudinal pitch of the cup-gripping member can be reduced. The present invention can directly enter the handling and boxing process after the film cutting process is completed, enabling continuous production and improving production efficiency.

Description

Technical Field

[0001] The present invention relates to the field of packaging machinery, and particularly to a linear filling device. Background Art

[0002] Cup-shaped products such as yogurt are usually produced and packaged in the form of connected cups, such as the common four-connected cups in two rows and two columns, six-connected cups in two rows and three columns, etc. After the connected cups are filled and sealed with a film, they are in a whole-piece array state. During the linear conveying process, it is necessary to cut between the connected cups to form independent connected cups. In addition, it is also necessary to indent between the single cups in a connected cup to facilitate breaking when the user takes them. However, the film-cutting components on the existing linear filling devices have relatively single functions, and most of them can only perform cutting operations alone, or perform step-by-step cutting and indenting operations on the connected cup products. For example, the film-cutting components disclosed in Chinese Patent Grant Publication No. CN106347731B, with the authorization date of November 13, 2018, and the name of "Three-dimensional Packaging Machine", and Chinese Patent Grant Publication No. CN209617660U, with the authorization date of November 12, 2019, and the name of "A Sealing and Cutting Device" are all designed based on the above functions. This results in a complex overall structure and numerous processes for the film-cutting components used in the production of connected cup products, and relatively low production and packaging efficiency.

[0003] After the film is cut, the connected cups need to be transported from the conveying component and packed into boxes. In some technologies, robots are used to perform the handling and packing operations on the connected cups. Such technologies have relatively high costs. In more technologies, arrayed cup-grabbing parts (such as grippers, suction cups, etc.) are used to grab the connected cups and stack them in the boxes. For example, the patent with the Chinese Patent Grant Publication No. CN102431677B, with the authorization date of March 12, 2014, and the name of "An Automatic Cup-Grabbing Mechanism in a Plastic Cup Packing Machine" adopts this structure, which is also a widely used handling and packing technology at present. To facilitate the cup-grabbing parts to grab the connected cups from the conveying component, there is generally a gap between each cup-grabbing part. This causes a large gap between the connected cups when the cup-grabbing parts transport the connected cups into the box, resulting in low utilization rate of the space inside the box, unstable stacking, easy dislocation, and even the situation where the connected cups are mutually crushed during packing.

[0004] In addition to the respective problems of the above-mentioned film-cutting components and handling and packing components, there is also the problem that the continuity between the film-cutting process and the packing process is not high during the production of connected cups, which affects the production efficiency. Summary of the Invention

[0005] Aiming at the defects of the above-mentioned existing linear filling technology, the present invention provides a linear filling device, which can achieve the following technical effects:

[0006] 1) Improve the design of the film cutting component, so that the film cutting component can complete the horizontal and vertical cutting between the linked cups and the horizontal and vertical creasing between the single cups, simplify the structure, optimize the process, and improve the production and packaging efficiency;

[0007] 2) The distance between each cup grabbing part is adjustable, which is convenient for the cup grabbing part to grab the cup group, and can also reduce the distance between the cup grabbing parts before packing, so that the cup groups are close to each other, improving the space utilization rate in the box, stacking tightly and not easy to be misplaced, and preventing the cup groups from collapsing each other;

[0008] 3) After the film cutting process is completed, the cup can directly enter the handling and packing process, so as to achieve continuous production and improve production efficiency.

[0009] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a linear filling device, comprising a conveying component, a film cutting component, and a transport and packing component. The conveying component is provided with a template, and the template is provided with mold holes in a horizontal and vertical array. The template is driven by the conveying component to be transported along a straight line and passes through the film cutting component and the transport and packing component in sequence.

[0010] The film cutting component includes a longitudinal film cutting component and a transverse film cutting component. The longitudinal film cutting component includes a longitudinal cutting component and a longitudinal creasing component. The longitudinal cutting component and the longitudinal creasing component are arranged alternately in the transverse direction. The longitudinal cutting component includes a first roller. The longitudinal creasing component includes a second roller. The rotating axis of the first roller and the rotating axis of the second roller are both arranged in the transverse direction. The transverse film cutting component includes a transverse cutting component and a transverse creasing component. The transverse creasing component and the transverse cutting component are arranged side by side in the longitudinal direction. The transverse cutting component is distributed at intervals in the transverse direction. The transverse cutting component includes a third roller and a driving cylinder. The driving cylinder drives the third roller to perform linear reciprocating motion in the transverse direction. The rotating axis of the third roller is arranged in the longitudinal direction. The transverse creasing component includes a cutter and a lifting cylinder I. The cutter is arranged in the transverse direction. The lifting cylinder I drives the cutter to perform lifting motion in the vertical direction.

[0011] The longitudinal direction is parallel to the template conveying direction, and the transverse direction is perpendicular to the template conveying direction. The cups are placed in the mold holes of the array as a whole piece. When the template is conveyed forward in the longitudinal direction, the first roller cuts the linked cups longitudinally, and the second roller makes longitudinal indentations between single cups. When the template stops conveying, the driving cylinder drives the third roller to move in a transverse straight line to cut the linked cups transversely, and the lifting cylinder I drives the cutter down to make transverse indentations between single cups. At this point, the linked cup product completes cutting and indentation in both the transverse and longitudinal directions, simplifies the structure, optimizes the process, and thus improves production and packaging efficiency.

[0012] In order to enable the first hob and the third hob to accurately cut the cup-connected product, grooves are provided on the template in a horizontal and vertical distribution. When the longitudinal cutting assembly operates, the vertically distributed grooves are located directly below the first hob. When the transverse cutting assembly operates, the horizontally distributed grooves are located directly below the third hob. In this way, the heights of the first hob and the third hob can be lowered, enabling the first hob and the third hob to move in the grooves, increasing the cutting amount of the cup-connected product, and thus cutting the cup-connected product.

[0013] Specifically, the longitudinal cutting assembly, the longitudinal indentation assembly, and the transverse cutting assembly all include adjustment cylinders. The first hob, the second hob, and the third hob are connected to the lower ends of the corresponding adjustment cylinders. When the piston rods of the adjustment cylinders extend and retract, they drive the first hob, the second hob, and the third hob to move up and down in the vertical direction. In actual use, the hobs will become dull, and the wear conditions of each hob are different. Therefore, when the hob wears, the amount of extension and retraction of the piston rod of the adjustment cylinder is adjusted according to the different wear degrees of the hob, so as to ensure that the cutting and indentation effects of the first hob, the second hob, and the third hob on the cup-connected product are in the best state.

[0014] The number of the second hobs and the cutting knives is arranged according to the number of horizontal rows and vertical columns of the single cups in a group of cup-connected products. At least one second hob is arranged between two adjacent first hobs, and at least one cutting knife is arranged between the first hob and the third hob.

[0015] To improve the flexibility of the longitudinal film cutting component and the transverse film cutting component in vertical movement, this film cutting component further includes a lifting component. The lifting component includes a motor I, a synchronous belt I, a fixed seat, and a load-carrying seat. The motor I and the synchronous belt I are both installed on the fixed seat. The synchronous belt I is unfolded in the vertical direction. The load-carrying seat is fixed on the straight section of the synchronous belt I. The transverse film cutting component and the longitudinal film cutting component are both installed on the load-carrying seat. The motor I drives the synchronous belt I to operate and drives the load-carrying seat to move up and down in the vertical direction, thereby adjusting the working heights of the first hob, the second hob, the third hob, and the cutting knife.

[0016] A sliding frame is provided on the load-carrying seat. The transverse cutting assembly is installed on the sliding frame. The sliding frame is slidably arranged on the load-carrying seat through a horizontally extending guide rail. The piston rod of the driving cylinder is connected to the sliding frame. The driving cylinder drives the sliding frame to perform a horizontal linear motion along the guide rail, and multiple groups of third hobs on the sliding frame also move horizontally therewith, reducing the stroke of the piston rod of the driving cylinder while ensuring the transverse cutting of the entire cup-connected product.

[0017] Specifically, the transverse indentation assembly further includes a connecting plate and a pressing plate. The cutting knife and the pressing plate are both installed on the connecting plate. The connecting plate is connected to the lower end of the piston rod of the lifting cylinder I. The number of pressing plates is two. The two pressing plates are elastically installed on both sides of the cutting knife through elastic members. When the piston rod of the lifting cylinder I expands and contracts, it drives the connecting plate to descend, and the pressing plates press on the cup connecting product, ensuring that the cutting knife can be prepared for transverse indentation. The cutting knife is in a multi-segment form, and the structure of each segment of the cutting knife is the same. In one segment of the cutting knife, the height of the cutting knife gradually becomes higher from the middle to both ends. The middle position of the cutting knife cuts deeper, and the two ends of the cutting knife cut shallower. In this way, it can not only ensure the shape of the cup connection but also ensure that users can easily break the cup connection.

[0018] The handling and packing component includes a top plate, cup-grabbing members, and a displacement component. The cup-grabbing members are arranged in an array on the top plate in the transverse and longitudinal directions. The top plate is driven by the displacement component to perform linear reciprocating motions in the vertical and horizontal directions. It also includes a transverse pitch-changing component and a longitudinal pitch-changing component. There are load-carrying plates arranged horizontally on the top plate. The load-carrying plates are slidably installed at the lower end of the top plate through transverse guide rails. The transverse pitch-changing component is installed on the top plate and drives each load-carrying plate to perform linear motions with different distances in the transverse direction. The cup-grabbing members are arranged longitudinally on the load-carrying plates. The cup-grabbing members are slidably installed at the lower end of the load-carrying plates through longitudinal guide rails. The longitudinal pitch-changing component is installed on the load-carrying plates and drives each cup-grabbing member to perform linear motions with different distances in the longitudinal direction.

[0019] Each load-carrying plate is arranged horizontally on the top plate. The transverse pitch-changing component drives each load-carrying plate to slide on the transverse guide rails and the sliding distances of each load-carrying plate are different, so as to achieve the effect of shortening the transverse pitch of the load-carrying plates. Since the cup-grabbing members are installed on the load-carrying plates, when the transverse pitch-changing component operates, it can shorten the transverse pitch of the cup-grabbing members, making the cup-grabbing members approach each other horizontally; each cup-grabbing member is arranged longitudinally on the load-carrying plate. The longitudinal pitch-changing component drives each cup-grabbing member to slide on the longitudinal guide rails and the sliding distances of each cup-grabbing member are different, so as to achieve the effect of shortening the longitudinal pitch of the cup-grabbing members, making the cup-grabbing members approach each other longitudinally. In summary, after the cup-grabbing members grab the cups, before packing, through the adjustment of the transverse pitch-changing component and the longitudinal pitch-changing component, the transverse pitch and longitudinal pitch of the cup-grabbing members can be reduced, so that the cups approach each other, improving the utilization rate of the space inside the box during packing, making the cups stack tightly and not easily misaligned, and preventing mutual extrusion.

[0020] The structures of the horizontal pitch-changing component and the vertical pitch-changing component are similar. Specifically, the horizontal pitch-changing component includes a first driving cylinder, a first swing rod, and a number of first connecting rods. One end of the first swing rod is hinged to the top plate, the cylinder block of the first driving cylinder is hinged to the top plate, the piston rod of the first driving cylinder is hinged to the first swing rod, the number of the first connecting rods is determined by the number of the load-carrying plates to be driven, one end of each first connecting rod is hinged to the swing rod, and the other end of each first connecting rod is hinged to the corresponding load-carrying plate. When the piston rod of the first driving cylinder extends or retracts, it drives the first swing rod to rotate, drives the movement of each first connecting rod on the first swing rod, and thus drives the load-carrying plate to slide. Since the lengths of the first connecting rods are different, the longer the first connecting rod, the shorter the sliding distance of the load-carrying plate. When the piston rod of the first driving cylinder extends, the distance between the load-carrying plates becomes larger; when the piston rod of the first driving cylinder retracts, the distance between the load-carrying plates becomes smaller.

[0021] In view of the large number of cup-gripping parts arranged horizontally, in order to avoid the first driving cylinder from bearing too many load-carrying plates and also avoid the first connecting rod being too long from affecting the transmission progress, two sets of horizontal pitch-changing components are arranged. The two sets of horizontal pitch-changing components are symmetrically arranged at the horizontal two ends of the cup-gripping parts, and each set of horizontal pitch-changing components controls the cup-gripping parts on one side to perform linear movement towards each other horizontally.

[0022] The vertical pitch-changing component includes a second driving cylinder, a second swing rod, and a number of second connecting rods. One end of the second swing rod is hinged to the load-carrying plate, the cylinder block of the second driving cylinder is hinged to the load-carrying plate, the piston rod of the second driving cylinder is hinged to the second swing rod, the number of the second connecting rods is determined by the number of the cup-gripping parts to be driven, one end of each second connecting rod is hinged to the swing rod, and the other end of each second connecting rod is hinged to the corresponding cup-gripping part. When the piston rod of the second driving cylinder extends or retracts, it drives the second swing rod to rotate, drives the movement of each second connecting rod on the second swing rod, and thus drives the cup-gripping part to slide. Since the lengths of the second connecting rods are different, the longer the second connecting rod, the shorter the sliding distance of the cup-gripping part. When the piston rod of the second driving cylinder extends, the distance between the cup-gripping parts becomes larger; when the piston rod of the second driving cylinder retracts, the distance between the cup-gripping parts becomes smaller.

[0023] In order to meet the lifting and translation capabilities of the top plate, the displacement assembly includes a lifting assembly and a translation assembly. The lifting assembly includes a base plate, a lifting cylinder, and a fixed frame. The top plate is connected to the lower end of the fixed frame. The cylinder body of the lifting cylinder is fixed on the base plate. The piston rod of the lifting cylinder is connected to the fixed frame or the top plate. The fixed frame is installed on the base plate in a sliding manner. Specifically, a guide rod is provided on the fixed frame, and a sliding sleeve is provided on the base plate. The guide rod is arranged in the vertical direction. The guide rod is slidably arranged in the sliding sleeve. The stability of the lifting of the fixed frame is increased by the cooperation of the guide rod and the sliding sleeve. When the piston rod of the lifting cylinder is extended and retracted, it drives the fixed frame to perform linear reciprocating motion in the vertical direction. The translation assembly includes a motor, a synchronous belt, and a slide rail. The synchronous belt is extended in the horizontal direction. The base plate is fixed on the straight section of the synchronous belt. The base plate is installed on the slide rail in a sliding manner. When the motor drives the synchronous belt to operate, it drives the base plate to perform linear reciprocating motion in the horizontal direction on the slide rail, so that the top plate obtains the displacement capability in the vertical and horizontal directions.

[0024] In order to make the cups more compact when packing, the cup grabbing parts include a fixed plate, a limit plate, and several suction cups. The fixed plate is mounted on the loading plate in a sliding manner. The fixed plate and the limit plate are arranged up and down and connected by a gas guide rod extending in the vertical direction. The suction cup is mounted on the limit plate and connected to the gas guide rod. In the horizontal or vertical direction, the height of the upper limit plate of the middle cup grabbing part is higher or lower than the height of the upper limit plates of the cup grabbing parts on both sides. For example, if the height of the middle limit plate is higher than the height of the limit plates on both sides, after the suction cup grabs the cup, the cup rests on the limit plate. Due to the height difference of the limit plates, the cup in the middle is higher than the cups on both sides. Therefore, when packing, the cup in the middle will be placed on the edges of the cups on both sides, forming an overlapping relationship, which makes the space utilization rate in the box higher. At the same time, the cups are more tightly connected, less likely to tip over, and more impact-resistant.

[0025] In order to prevent the suction cup from scratching the box when working, the grab cup member also includes a surrounding plate, which is arranged around the edge of the limiting plate and surrounds the suction cup. The grab cup member will open the box when working, and the up and down movement of the outer grab cup member will scratch the box. After adding the surrounding plate, the surrounding plate is in surface contact with the inner wall of the box to prevent the box from being scratched.

[0026] The advantages of the present invention are: 1) when the template is conveyed forward in the longitudinal direction, the first roller cuts the linked cups longitudinally, and the second roller makes longitudinal indentations between the single cups; when the template stops conveying, the driving cylinder drives the third roller to move in a transverse straight line to cut the linked cups transversely, and the lifting cylinder drives the cutter to descend to make transverse indentations between the single cups, thereby simplifying the structure, optimizing the process, and improving the production and packaging efficiency.

[0027] 2) After the cup-gripping member grabs the cups, before packing, through the adjustment of the lateral pitch-changing assembly and the longitudinal pitch-changing assembly, the lateral pitch and the longitudinal pitch of the cup-gripping member can be reduced, so that the cups approach each other, thereby improving the utilization rate of the space inside the box during packing. The cups are stacked tightly and are not easily misaligned, preventing mutual extrusion.

[0028] 3) The adjacent limiting plates are in a state of one being higher and the other being lower. When packing, the middle cup will rest on the cups on both sides, forming a mutually overlapping relationship. The utilization rate of the space inside the box is higher. At the same time, the cups are more tightly packed, are more difficult to topple, and have stronger impact resistance.

[0029] 4) Along the linear conveying direction of the conveying component, the connected cups first pass through the film-cutting component to cut the film, and then pass through the handling and packing component for handling and packing. The whole process is continuous and complete, and the production efficiency is greatly improved. Description of the Drawings

Therefore, it cannot be understood as a limitation to the present invention. In addition, terms such as "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0045] The present invention will be further described below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0046] Embodiment of the present invention:

[0047] A linear filling device, as Figure 1As shown in the figure, it includes a conveying component 100, a storage component 101, a dust removal component 102, a sterilization component 103, a filling component 104, a sealing component 105, a film cutting component 200, and a handling and packing component 300. Among them, the storage component 101 (for storing cup products), the dust removal component 102 (for removing dust inside the cup products), the sterilization component 103 (for sterilizing the inside of the cup products), the filling component 104 (for filling materials into the cup products), and the sealing component 105 (for sealing the cup products filled with materials) are all prior arts, and their specific structures will not be elaborated in this embodiment. A template 218 is provided on the conveying component. The template is provided with a transverse and longitudinal array of die holes 201. The template is driven by the conveying component to be conveyed linearly and sequentially passes through the storage component 101, the dust removal component 102, the sterilization component 103, the filling component 104, the sealing component 105, the film cutting component 200, and the handling and packing component 300.

[0048] As Figures 2 to 7 shown in the figure, the film cutting component 200 includes a longitudinal film cutting component 200, a transverse film cutting component 200, and a lifting component. The longitudinal film cutting component 200 and the transverse film cutting component 200 are both located above the template 218;

[0049] The template 218 is driven by the conveying component to be conveyed linearly. Taking the conveying direction parallel to the template 218 as the longitudinal direction and the direction perpendicular to the conveying direction of the template 218 as the transverse direction, the template 218 is provided with a transverse and longitudinal array of die holes 201. Before film cutting, the cups are in a whole piece structure and placed in the array of die holes 201 to be conveyed together with the template 218.

[0050] The longitudinal film cutting component 200 includes a longitudinal cutting assembly and a longitudinal indentation assembly. The longitudinal cutting assembly and the longitudinal indentation assembly are arranged alternately in the transverse direction. The longitudinal cutting assembly includes a first hob 202, and the longitudinal indentation assembly includes a second hob 203. The rotation axes of the first hob 202 and the second hob 203 are both arranged in the transverse direction.

[0051] The transverse film cutting component 200 includes a transverse cutting assembly and a transverse indentation assembly. The transverse indentation assembly and the transverse cutting assembly are arranged side by side in the longitudinal direction.

[0052] The transverse cutting assemblies are distributed at intervals in the transverse direction. The transverse cutting assembly includes a third hob 204 and a driving cylinder 205. The driving cylinder 205 drives the third hob 204 to perform a linear reciprocating motion in the transverse direction. The rotation axis of the third hob 204 is arranged in the longitudinal direction.

[0053] The horizontal indentation assembly includes a cutting knife 206, a lifting cylinder I 207, a connecting plate 208, and a pressing plate 209. The cutting knife and the pressing plate 209 are both installed on the connecting plate 208. The connecting plate 208 is installed at the lower end of the piston rod of the lifting cylinder I 207. The number of pressing plates 209 is two. The cutting knife 206 is arranged horizontally. The two pressing plates 209 are elastically installed on both sides of the cutting knife 206 through elastic members such as springs. When the piston rod of the lifting cylinder I 207 expands and contracts, it drives the connecting plate 208 to move up and down, thereby driving the cutting knife 206 and the pressing plate 209 to move up and down in the vertical direction.

[0054] The lifting component includes a motor I 210, a synchronous belt I 211, a fixed seat 212, and a load-carrying seat 213. The motor I 210 and the synchronous belt I 211 are both installed on the fixed seat 212. The synchronous belt I 211 is unfolded in the vertical direction. The load-carrying seat 213 is fixed on the straight section of the synchronous belt I 211. The horizontal film cutting component 200 and the vertical film cutting component 200 are both installed on the load-carrying seat 213. The motor I 210 drives the synchronous belt I 211 to operate and drives the load-carrying seat 213 to move up and down in the vertical direction, thereby adjusting the working heights of the first hob 202, the second hob 203, the third hob 204, and the cutting knife 206, and improving the flexibility of the vertical movement of the vertical film cutting component 200 and the horizontal film cutting component 200.

[0055] The working process of the film cutting component 200: Adjust the height of the load-carrying seat 213 through the lifting component so that each hob and the cutting knife 206 are in the working position. When the template 218 is conveyed linearly in the longitudinal direction, the first hob 202 performs longitudinal cutting between the connected cups. The second hob 203 performs longitudinal indentation between the single cups. When the template 218 stops conveying, the third hob 204 is driven by the driving cylinder 205 to move linearly in the horizontal direction to perform horizontal cutting between the connected cups. The cutting knife 206 is driven by the lifting cylinder I 207 to descend to perform horizontal indentation between the single cups. Thus, the connected cup product has completed cutting and indentation in both the horizontal and vertical directions, simplifying the structure and optimizing the process, thereby improving the production and packaging efficiency.

[0056] Taking the four - cup product after final film cutting as an example, that is, there are two rows horizontally and two columns vertically of single cups in a group of connected cups, and there are six groups of connected cups arranged horizontally in total. The number of the first hob 202 is determined according to the number of horizontally arranged groups of connected cups. Therefore, five first hobs 202 are arranged horizontally for vertical cutting. The number of the second hob 203 is determined according to the number of columns of single cups in a group of connected cups. Therefore, the first hob 202 and the second hob 203 are arranged alternately. Then, according to the number of horizontally arranged groups of four - cup products, six second hobs 203 are arranged in total for vertical indentation. The number of the cutter 206 is determined according to the number of rows of single cups in a group of connected cups. Therefore, one cutter 206 is arranged between the first hob 202 and the third hob 204 for horizontal indentation. It can be understood that the number of the second hob 203 and the cutter 206 can be increased or decreased correspondingly according to the increase or decrease of the number of rows and columns of single cups in a group of connected cups.

[0057] A carriage 214 is provided on the carrier base 213. The number of the third hob 204 is determined according to the stroke of the piston rod of the driving cylinder 205. In this embodiment, three third hobs 204 are installed at intervals horizontally on the carriage 214. The carriage 214 is slidably arranged on the carrier base 213 through a horizontally extending guide rail 215. The piston rod of the driving cylinder 205 is connected to the carriage 214. The driving cylinder 205 drives the carriage 214 to perform a horizontal linear motion along the guide rail 215. The third hob 204 on the carriage 214 also moves horizontally therewith, reducing the stroke of the piston rod of the driving cylinder 205 while ensuring horizontal cutting of the entire connected - cup product.

[0058] In order to enable the first hob 202 and the third hob 204 to accurately cut the connected - cup product, the template 218 is provided with grooves 216 distributed horizontally and vertically. When the vertical cutting assembly operates, the vertically distributed grooves 216 are located directly below the first hob 202. When the horizontal cutting assembly operates, the horizontally distributed grooves 216 are located directly below the third hob 204. In this way, the heights of the first hob 202 and the third hob 204 can be lowered, enabling the first hob 202 and the third hob 204 to move in the grooves 216, increasing the cutting amount of the connected - cup product, and thus cutting the connected - cup product.

[0059] Specifically, when the horizontal indentation assembly works, the pressing plate 209 presses on the connected - cup product to ensure that the cutter 206 can be prepared for horizontal indentation. The cutter 206 is multi - segmented, and the structure of each segment of the cutter 206 is the same. In one segment of the cutter 206, the height of the cutter 206 gradually increases from the middle to both ends. The middle position of the cutter 206 cuts deeper, and the two - end positions of the cutter 206 cut shallower. In this way, both the shape of the connected cup can be ensured and the user can easily break the connected cup.

[0060] Specifically, the longitudinal cutting assembly, the longitudinal indentation assembly, and the transverse cutting assembly all include an adjustment cylinder 217. The first hob 202, the second hob 203, and the third hob 204 are connected to the lower end of the corresponding adjustment cylinder 217. When the piston rod of the adjustment cylinder 217 expands and contracts, it drives the first hob 202, the second hob 203, and the third hob 204 to move up and down in the vertical direction. During actual use of the first hob 202, the second hob 203, and the third hob 204, the phenomenon of dull knives may occur, and the wear conditions of each hob are different. Therefore, after the hob wears, the expansion and contraction amount of the piston rod of the adjustment cylinder 217 is adjusted according to the different wear degrees of the hob, so as to ensure that the cutting and indentation effects of the first hob 202, the second hob 203, and the third hob 204 on the cup joint product are in the best state.

[0061] As Figures 7 to 13 shown in the figure, the handling and packing component 300 includes a top plate 301, a cup grasping member, a displacement component, and a pitch-changing component. The cup grasping members are arranged in a transverse and longitudinal array on the top plate 301. Taking the array mode of the cup grasping members shown Figure 7 as an example, there are six cup grasping members in each row horizontally and three cup grasping members in each column vertically (the number and arrangement mode of the cup grasping members can be adjusted according to the actual working conditions). The top plate 301 is driven by the displacement component to make linear reciprocating motions in the vertical and horizontal directions.

[0062] The displacement component includes a lifting component and a translation component.

[0063] The lifting component includes a base plate 302, a lifting cylinder II 303, and a fixing frame 304. The top plate 301 is connected to the lower end of the fixing frame 304. The cylinder body of the lifting cylinder II 303 is fixed on the base plate 302. The piston rod of the lifting cylinder II 303 is connected to the fixing frame 304 or the top plate 301. The fixing frame 304 is installed on the base plate 302 in a sliding manner. Specifically, guide rods 305 are provided on the fixing frame 304, and sliding sleeves 306 are provided on the base plate 302. The guide rods 305 are arranged in the vertical direction and are slidably arranged in the sliding sleeves 306. The cooperation of the guide rods 305 and the sliding sleeves 306 increases the stability of the lifting of the fixing frame 304. When the piston rod of the lifting cylinder II 303 expands and contracts, it drives the fixing frame 304 to make linear reciprocating motions in the vertical direction, so that the top plate 301 obtains the displacement ability in the vertical direction.

[0064] The translation component includes a motor II 307, a synchronous belt II 308, and a slide rail 322. The synchronous belt II 308 is unfolded in the horizontal direction. The base plate 302 is fixed on the straight section of the synchronous belt II 308. The base plate 302 is installed on the slide rail 322 in a sliding manner. When the motor II 307 drives the synchronous belt II 308 to operate, it drives the base plate 302 to make linear reciprocating motions in the horizontal direction along the slide rail 322, so that the top plate 301 obtains the displacement ability in the horizontal direction.

[0065] The variable pitch component includes a lateral variable pitch component and a longitudinal variable pitch component.

[0066] On the top plate 301, there are load-carrying plates 309 arranged horizontally. The load-carrying plates 309 are slidably mounted on the lower end of the top plate 301 through lateral guide rails 310. There are six load-carrying plates 309. The lateral variable pitch component is mounted on the top plate 301 and drives each load-carrying plate 309 to perform linear motion with different distances horizontally. Specifically, the lateral variable pitch component includes a first driving cylinder 311, a first swing rod 312, and several first connecting rods 313. One end of the first swing rod 312 is hinged on the top plate 301, the cylinder body of the first driving cylinder 311 is hinged on the top plate 301, the piston rod of the first driving cylinder 311 is hinged to the first swing rod 312. The number of the first connecting rods 313 is determined according to the number of load-carrying plates 309 to be driven. One end of each first connecting rod 313 is hinged on the swing rod, and the other end of the first connecting rod 313 is hinged to the corresponding load-carrying plate 309. When the piston rod of the first driving cylinder 311 extends and retracts, it drives the first swing rod 312 to rotate, drives the movement of each first connecting rod 313 on the first swing rod 312, thereby driving the load-carrying plate 309 to slide. Since the lengths of the first connecting rods 313 are different, the longer the first connecting rod 313, the shorter the sliding distance of the load-carrying plate 309. When the piston rod of the first driving cylinder 311 extends, the distance between the load-carrying plates 309 becomes larger, and when the piston rod of the first driving cylinder 311 retracts, the distance between the load-carrying plates 309 becomes smaller. Given that the number of cup-grabbing parts arranged horizontally is large, in order to avoid the first driving cylinder 311 bearing too many load-carrying plates 309 and also avoid the first connecting rod 313 being too long affecting the transmission progress, two groups of lateral variable pitch components are arranged. The two groups of lateral variable pitch components are symmetrically arranged at the horizontal two ends of the cup-grabbing parts. Each group of lateral variable pitch components controls the cup-grabbing parts on one side to perform linear motion towards each other horizontally. At this time, three first connecting rods 313 are installed on each first swing rod 312. When the first driving cylinder 311 on each side works, it drives three load-carrying plates 309 to translate respectively.

[0067] The cup-grabbing members are arranged on the carrier plate 309 in the longitudinal direction. The cup-grabbing members are installed at the lower end of the carrier plate 309 in a sliding manner through the longitudinal guide rail 323. There are three cup-grabbing members on each carrier plate 309. The number of longitudinal pitch-changing assemblies is equal to the number of carrier plates 309, that is, there are six groups. The longitudinal pitch-changing assemblies are installed on the carrier plate 309 and drive each cup-grabbing member to perform linear motion of different distances in the longitudinal direction. Specifically, the longitudinal pitch-changing assembly includes a second driving cylinder 314, a second swing rod 315, and a plurality of second connecting rods 316. One end of the second swing rod 315 is hinged on the carrier plate 309. The cylinder body of the second driving cylinder 314 is hinged on the carrier plate 309. The piston rod of the second driving cylinder 314 is hinged to the second swing rod 315. The number of the second connecting rods 316 is determined according to the number of cup-grabbing members to be driven. One end of each of the second connecting rods 316 is hinged to the swing rod, and the other end of the second connecting rod 316 is hinged to the corresponding cup-grabbing member. When the piston rod of the second driving cylinder 314 is extended or retracted, it drives the second swing rod 315 to rotate, driving the second connecting rods 316 on the second swing rod 315 to move, thereby driving the cup-grabbing member to slide. Since the lengths of the second connecting rods 316 are different, the longer the second connecting rod 316, the shorter the sliding distance of the cup-grabbing member. When the piston rod of the second driving cylinder 314 is extended, the distance between the cup-grabbing members becomes larger, and when the piston rod of the second driving cylinder 314 is retracted, the distance between the cup-grabbing members becomes smaller.

[0068] In order to make the cup 400 more compact when packed, as Figure 9 As shown in , the cup grabbing member includes a fixed plate 317, a limiting plate 318, and a plurality of suction cups 319. The number and arrangement of the suction cups 319 are determined according to the cup combination. For example, a four-cup combination uses four suction cups 319 arranged in two rows and two columns. The fixed plate 317 is mounted on the carrier plate 309 in a sliding manner. The fixed plate 317 and the limiting plate 318 are arranged up and down and connected by an air guide rod 320 extending in the vertical direction. The suction cup 319 is mounted on the limiting plate 318 and establishes an air path connection with the air guide rod 320. In the horizontal or vertical direction, the height of the upper limit plate 318 of the middle cup grabbing member is higher or lower than the height of the upper limit plates 318 of the cup grabbing members on both sides. As shown in Figure 9 , Figure 13 As shown in the figure, in the longitudinal direction, the height of the middle limiting plate 318 is higher than the height of the limiting plates 318 on both sides. For example, after the suction cup 319 absorbs the cup 400, the cup 400 rests on the limiting plate 318. Due to the height difference of the limiting plates 318, the middle cup 400 is higher than the cups 400 on both sides. Therefore, when packing, the middle cup 400 will be overlapped on the edges of the cups 400 on both sides to form an overlapping relationship, which has a higher space utilization rate in the box. At the same time, the cups 400 are more tightly packed, less likely to tip over, and have stronger impact resistance.

[0069] In order to prevent the suction cup 319 from scratching the box during operation, the cup-gripping member further includes a surrounding plate 321. The surrounding plate 321 is arranged around the edge of the limiting plate 318 and encloses the suction cup 319. When the cup-gripping member works, it will expand the box. When the outer cup-gripping member moves up and down, the limiting plate 318 and the suction cup 319 will scratch the box, resulting in damage to the box. After adding the surrounding plate 321, when the cup-gripping member moves, the surrounding plate 321 makes surface contact with the inner wall of the box, having a buffering effect to prevent the box from being scratched and damaged.

[0070] Working principle of the handling and packing component 300: Taking the conveying direction parallel to the cup 400 as the longitudinal direction and the direction perpendicular to the conveying direction of the cup 400 as the transverse direction, the structures of the transverse pitch-changing component and the longitudinal pitch-changing component are similar. Each load-carrying plate 309 is arranged horizontally on the top plate 301. The transverse pitch-changing component drives each load-carrying plate 309 to slide on the transverse guide rail 310 and the sliding distances of the load-carrying plates 309 are different, so as to shorten the transverse pitch between the load-carrying plates 309. Since the cup-gripping member is installed on the load-carrying plate 309, when the transverse pitch-changing component operates, it can shorten the transverse pitch between the cup-gripping members, causing the cup-gripping members to approach each other horizontally; each cup-gripping member is arranged longitudinally on the load-carrying plate 309. The longitudinal pitch-changing component drives each cup-gripping member to slide on the longitudinal guide rail 323 and the sliding distances of the cup-gripping members are different, so as to shorten the longitudinal pitch between the cup-gripping members, causing the cup-gripping members to approach each other longitudinally. In summary, the lifting group enables the cup-gripping member to obtain the displacement ability in the horizontal and vertical directions. After the cup-gripping member grabs the cup 400 and before packing, through the adjustment of the transverse pitch-changing component and the longitudinal pitch-changing component, the transverse pitch and the longitudinal pitch between the cup-gripping members can be reduced, so that the cups 400 approach each other, improving the utilization rate of the space inside the box during packing, making the cups 400 stacked tightly and not easily misaligned, and preventing mutual extrusion.
