Description

TECHNICAL FIELD

[0001] The present application belongs to the field of agricultural planting machinery, and particularly relates to a grape bagging device based on a shed frame type planting. BACKGROUND

[0002] Grape bagging is a planting technique, that is, a cluster of grapes is covered with a special bag or cover during the development of grape fruits to protect the grape fruits from the invasion of pests and diseases and to improve the color, sugar content and quality of the fruits. The significance of grape bagging lies in that it can effectively reduce the harm of pests and diseases to grapes, reduce the use amount of chemical pesticides, reduce the pollution to the environment, and also can improve the sales price and market competitiveness of grape fruits. Therefore, the adoption of grape bagging technology helps to improve the yield and quality of grape planting, and is a modern and environmentally-friendly cultivation method.

[0003] At present, the main planting method of grapes in China is shed frame and hedge frame. The grape bagging device designed this time is mainly for shed frame type planting. The shed frame type planting is an improved cultivation method, which can make grape fruits as regularly suspended in the air as possible, and the spacing between the fruits is larger, and the obstacles encountered in the bagging are also less. The working environment formed by the cultivation method provides the possibility for the grape bagging machine to perform bagging work. The conventional manual bagging of grape clusters is time-consuming and labor-intensive, and needs to wrap the packaging bag around the grape, bundle the bag opening, and finally bundle the stem of the grape with the bag opening through adhesive tape. The above manual method is time-consuming and labor-intensive, and the automatic bagging machine can greatly improve the bagging efficiency and greatly reduce the labor cost, thereby improving the production efficiency. As part of agricultural mechanization and intelligentization, the research and application of the bagging machine can promote the intelligent development of agricultural production.

[0004] In summary, how to realize the automatic bagging of shed frame type planted grapes has become a problem that researchers in the field urgently need to solve. SUMMARY

[0005] The technical problem to be solved by the present application is how to realize the automatic bagging of shed frame type planted grapes.

[0006] To solve the above technical problems, the technical scheme adopted by the present application is:

[0007] The application is a grape bagging device based on shed planting, comprising: a rack provided with a walking assembly at the bottom; a lifting module provided on the rack; a front extension module provided at the execution end of the lifting assembly; a packaging mechanism provided at the execution end of the front extension module; a bag supply assembly provided on the bottom plate of the rack, provided with a packaging suitable for the adsorption of the bag opening assembly in the packaging mechanism; the bag supply assembly comprises: a bag storage box with an opening at the top; a pressing strip fixedly provided at the top of the bag storage box; a first support plate on which the packaging bag is placed, provided with an elastic member between the first support plate and the bottom of the bag storage box, so that the packaging bag is pressed between the pressing strip and the first support plate; a tray horizontally outwardly extended at the opening of the top of the bag storage box; a paper feeding roller driven to rotate by a conveying motor and provided at the top of the bag storage box, with the bottom abutting against the packaging bag; when the paper feeding roller rotates, the packaging bag pressed between the pressing strip and the first support plate is moved to the tray under the action of friction, and the bag opening assembly in the packaging mechanism is adsorbed to the packaging bag on the tray under the cooperation of the lifting module and the front extension module, so as to open the packaging bag, and then the packaging bag is sleeved on the grape outside through the lifting module and the front extension module, and the grape is bound and tied through the packaging mechanism.

[0008] In the scheme, the rack walks through the walking assembly, and when moving to the grape to be sleeved with the bag, the lifting module and the front extension module on the rack drive the packaging mechanism to move linearly along two axes, the bag supply assembly places the packaging bag on the tray, the packaging mechanism moves to adsorb the packaging bag, and then the packaging mechanism resets to sleeve the grape with the open packaging bag, and then the packaging mechanism binds and ties the grape together with the stem, so as to realize the automatic bagging of the grape planted in the shed.

[0009] In this way, only the packaging bag needs to be placed on the first support plate, and the packaging bag is pressed between the first support plate and the pressing strip under the action of the elastic force, the paper feeding roller rotates to convey the uppermost packaging bag to the tray through friction.

[0010] In order to realize that only the uppermost packaging bag moves to the tray, the rubber strip is arranged at the connection between the tray and the bag storage box.

[0011] The rotation of the paper feeding roller, the friction f1 between the paper feeding roller and the first paper, pushes the first paper to move forward; the sliding of the first paper generates the friction f2 between the first paper and the second paper, which pushes the second paper to move forward and prevents the first paper from moving forward; the sliding of the second paper generates the friction f3 between the second paper and the third paper, which prevents the second paper from moving forward; thus, it can be concluded that if only the first paper is allowed to slide and enter the tray, f1 needs to be greater than f2; and f3 needs to be greater than f2, but f3 being greater than f2 obviously cannot be achieved, so a rubber strip is arranged at the end of the tray to introduce f4, so that the friction force condition for the component to feed one paper at a time can be obtained as follows:

[0012] f1>f2,f3+f4>f2;To achieve this condition, the surface friction factor of the paper feeding roller needs to be greater than the friction factor of the paper bag, and the friction factor of the rubber strip at the end of the tray is not required and is appropriate.

[0013] In order to illustrate the specific structure of the walking assembly, the walking assembly comprises: a damping support arranged at the bottom corner of the frame; a hinge hingedly connected with the damping support and connected with the damping support through a damping spring; two wheel set connecting plates arranged on both sides of the hinge and rotatably connected with the same hub motor; and a walking wheel connected with the hub motor.

[0014] Since the ground environment on which the device walks is uneven soil environment, the hinge is hingedly connected with the damping support, and the damping spring is connected with the hinge and the damping support, so that when the uneven road surface is needed, the hinge will rotate relative to the damping support, the damping spring ensures the resetting of the hinge after turning over, the hub motor drives the walking wheel to walk, and further drives the device to walk.

When the bag opening assembly adsorbs the packaging bag and opens it, the bag opening of the packaging bag is placed between the upper opening and the lower opening, the grapes fall into the packaging bag through the upper opening, the bunching assembly works to bunch the bag opening of the packaging bag together with the stem of the grapes, and the bundling assembly works to bundle the bag opening of the packaging bag together with the stem of the grapes with adhesive tape and cut off the adhesive tape after bundling.

[0021] In this scheme, the bag opening assembly, the bundling assembly and the bunching assembly are arranged in sequence from top to bottom between the upper opening and the lower opening. The bag opening assembly is used to open the bag opening of the packaging bag until the bundling is completed, the bunching assembly is used to bunch the bag opening of the packaging bag together with the stem of the grapes, and the bundling assembly is used to bundle the bag opening. In this way, the packaging bag can be sleeved on the grapes, and automatic bagging and packaging of the grapes are realized.

[0022] Similarly, when the grapes are sold, the operator only needs to hold the stem to realize the packaging of the grapes, and automatic bagging and packaging of the grapes are realized.

[0023] In order to illustrate the specific structure of the bag opening component in the packaging mechanism, the bag opening component comprises: a first suction cup fixed at the upper support plate through a first suction cup frame and located above one side of the lower opening; a support plate slidingly arranged at the bottom of the upper support plate through a first power assembly; a turnover frame rotatingly arranged at the bottom of the support plate controlled by a rotating motor; a second suction cup fixed at the turnover frame and located above the other side of the lower opening; when the second suction cup is controlled by the rotating motor to reverse to a downward state, the packaging bag is adsorbed at this time, and after the adsorption is completed, the second suction cup is rotated to be opposite to the first suction cup, and the second suction cup is moved close to the first suction cup through the first power assembly, the other side of the packaging bag is adsorbed by the first suction cup, and the first power assembly is reset to open the bag opening of the packaging bag.

[0024] The second suction cup can not only adsorb the bag downward under the driving of the rotating motor, but also can move linearly along the length direction of the frame under the driving of the first power assembly. The second suction cup is rotated to a horizontal state and is close to the first suction cup, and then the second suction cup and the first suction cup are far away from each other to open the bag opening of the packaging bag, so that the grapes can enter.

The plurality of arc-shaped blades are simultaneously rotated, the inner side arc acts on the bag opening to band the bag opening, and the twisted grape stems are pushed to the middle during the contraction process, so that the subsequent binding mechanism can work conveniently.

[0029] The bottom plate is further provided with two tensioning wheels; the two tensioning wheels are located on both sides of the synchronous wheel and are arranged through the synchronous belt;

[0030] The motor drives the main synchronous pulley to rotate, but considering that the span of the synchronous belt is large, the length of the synchronous belt is not easy to control, therefore, two tensioning wheels are arranged between the main synchronous pulley and the rotor, so that the effective length of the synchronous belt can be adjusted.

[0031] In order to illustrate the specific structure of the arc-shaped blades and the rotor, the thickness of the arc-shaped blades is 1 / 2 of the thickness of the rotor; the arc-shaped blades are arranged obliquely upward at the connection with the rotor.

[0032] In order to ensure that the blades always maintain a stacked state during work, the upper surface of the rotor is an inclined surface, and the thickness of the rotor is 5 mm, so that the arc-shaped blades can be stacked with each other during installation, the thickness of the entire device is reduced, and the deformation of the arc-shaped blades caused by extrusion between the arc-shaped blades during rotation is reduced; as for the blades, the blades are designed to be narrow at the top and wide at the bottom, and the thickness is 2.5 mm, which is also to ensure that the arc-shaped blades can always maintain a stacked state during work, but the blades will inevitably deform during rotation, so the material of the arc-shaped blades is selected to be high-toughness and smooth-surface acrylic resin.

[0034] The ratchet wheel and the pawl are matched in shape, the pawl is engaged in the groove of the ratchet wheel as much as possible to ensure that the adhesive tape is adhered sufficiently; the front ends of the profile frame and the cutter frame need to be pinched tightly, so the length of the profile frame is longer than that of the cutter frame, and the front end of the profile frame is placed on the support section of the cutter frame; the size of the cutter frame needs to be ensured to be able to cut off the adhesive tape smoothly after the cutter frame is forced to rotate by a certain angle, the adhesive tape is installed on the rotating column of the second box body during installation, the adhesive tape is wound on the ratchet wheel through the guide column, the pawl embeds the adhesive tape in the groove of the ratchet wheel and adheres the adhesive tape to the surface for taking out the adhesive tape, the first box body and the second box body have a gap, and the gap is rounded at the inlet to facilitate the bag opening to enter the channel; during bundling, the bundled bag opening passes through the gap, the pawl is pushed to move downward and pulls out the adhesive tape around the bag opening, after the adhesive tape is wound, the pawl re-engages the excess adhesive tape with the ratchet wheel; then the bag opening continues to advance, the cutter on the cutter frame cuts off the adhesive tape, at the same time, the profile frame and the cutter frame pinch the cut adhesive tape; after the bundling is completed, each part returns to the initial position through the spring, the pawl re-embeds the adhesive tape in the groove of the ratchet wheel and adheres the adhesive tape to the surface, and the cycle is completed.

[0055] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0056] like Figures 1-3 As shown, this invention is a grape bagging device based on trellis planting, comprising: a frame 100, with a walking component 110 at its bottom; a lifting module 120 mounted on the frame 100; a forward extension module 130 located at the execution end of the lifting component 120; a packaging mechanism 140 located at the execution end of the forward extension component 130; and a bag supply component 150 mounted on the bottom plate of the frame 100, which is provided with packaging suitable for adsorption by the bag-opening component 2 in the packaging mechanism 140. The bag supply component 150 includes: a storage box 151 with an opening at the top; a pressure strip 152 fixedly mounted on the top of the storage box 151; and a first support plate 153 on which a packaging bag is placed, with an elastic element 154 positioned between the support plate and the bottom of the storage box 151 to press the packaging bag down. Between the pressure strip 152 and the first support plate 153; a tray 156 is provided horizontally outward from the top opening of the storage bag box 151; a paper feeding roller 157 is driven to rotate on the top of the storage bag box 151 by a conveying motor 155, and its bottom abuts against the packaging bag; when the paper feeding roller 157 rotates, the packaging bag pressed between the pressure strip 152 and the first support plate 153 is moved to the tray 156 under the action of friction. With the cooperation of the lifting module 120 and the forward extension module 130, the bag opening component 2 in the packaging mechanism 140 is used to absorb the packaging bag on the tray 156, opening the packaging bag. Then, the lifting module 120 and the forward extension module 130 cover the grapes with the packaging bag. The packaging mechanism 140 then binds and ties the grapes.

[0057] In the scheme, the rack walks through the walking assembly, when moving to the grape to be bagged, the lifting module and the front extension module on the rack drive the packaging mechanism to move linearly in two axes, the bag feeding assembly places the packaging bag on the tray, the packaging mechanism moves to adsorb, then the packaging mechanism resets to set the open packaging bag into the grape, then the packaging mechanism bundles and ties the grape together with the stem, realizing the automatic bagging of the grape planted in the rack;

[0058] In this way, only the packaging bag is placed on the first support plate by manual operation, and the packaging bag is pressed between the first support plate and the pressing strip under the action of the elastic force. The paper feeding roller rotates to convey the uppermost packaging bag to the tray through friction force for the suction of the bag opening assembly of the packaging mechanism.

[0059] As shown in the Figures 2-3 In order to realize the movement of only the upper packaging bag to the tray, the tray 156 is provided with a rubber strip 158 at the connection with the bag storage box 151.

[0060] As shown in the Figure 4 The paper feeding roller rotates, the friction force f1 between the paper feeding roller and No. 1 paper, pushes No. 1 paper to move forward; No. 1 paper sliding generates the friction force f2 between No. 1 paper and No. 2 paper, pushes No. 2 paper to move forward, prevents No. 1 paper from moving forward; No. 2 paper sliding generates the friction force f3 between No. 2 paper and No. 3 paper, prevents No. 2 paper from moving forward; thus it can be concluded that if only No. 1 paper is allowed to slide and enter the tray, f1 needs to be greater than f2; and f3 needs to be greater than f2, but f3 greater than f2 obviously cannot be realized, so a rubber strip is arranged at the end of the tray to introduce f4, thus the friction force condition for each time only one paper is conveyed by the component can be obtained: f1>f2, f3+f4>f2; in order to realize the condition, the surface friction factor of the paper feeding roller is required to be greater than the friction factor of the paper bag, and the friction factor of the rubber strip at the end of the tray is not required to be appropriate.

[0062] The hinge is hinged to the damping support, and the damping spring is connected to the hinge and the damping spring, so that when uneven road surface is needed, the hinge can rotate relative to the damping support, and the damping spring ensures the resetting of the hinge after turning over, the wheel hub motor drives the walking wheel to walk, and further drives the device to walk.

[0063] As Figure 6 shown, in order to illustrate the specific structure of the lifting module, the lifting module 120 of the present application comprises: two lifting frames 121 arranged on both sides of the rack 100; a lifting table 122 slidingly arranged on both sides of the lifting frame 121; a lifting motor 123 fixedly connected with the lifting frame 121; and a lifting chain 124 vertically wound on the lifting frame 121 and driven to rotate by the lifting motor 123, wherein one link is fixedly connected with the lifting table 122.

[0064] In the present scheme, the lifting frame is fixedly arranged and provides a lifting table for lifting, the lifting motor is fixed on the lifting frame, the lifting chain is vertically wound on the lifting frame through sliding, the lifting motor drives the lifting chain to rotate, the lifting table is fixedly connected with one link on the lifting chain, and the lifting chain drives the lifting table to lift along the lifting frame.

[0065] In the present scheme, the lifting frame is fixedly arranged and provides a lifting table for lifting, the lifting motor is fixed on the lifting frame, the lifting chain is vertically wound on the lifting frame through sliding, the lifting motor drives the lifting chain to rotate, the lifting table is fixedly connected with one link on the lifting chain, and the lifting chain drives the lifting table to lift along the lifting frame.

[0066] As Figure 6 shown, in order to illustrate the specific structure of the front extension module, the front extension module 130 of the present application comprises: a front extension motor 131 fixed on the lifting table 122; a front extension chain 132 horizontally wound on the lifting table 122 and driven to rotate by the front extension motor 131, wherein one link is fixedly connected with the packaging mechanism 140; and the bottom of the lifting table 122 is slidingly connected with the packaging mechanism 140.

[0067] The packaging mechanism is slidingly connected with the bottom of the lifting table, so that the packaging mechanism can be horizontally extended, the front extension motor is arranged on the bottom of the lifting table, the front extension chain is arranged on the bottom of the lifting table and controlled to rotate by the front extension motor, and the top of the packaging mechanism is fixedly connected with one link of the front extension chain, so that the rotation of the front extension chain can drive the packaging mechanism to horizontally extend from the bottom of the lifting table.

[0068] As Figures 7-8As shown, to illustrate the specific structure of the packaging mechanism, the present invention employs a packaging mechanism 140 comprising: a frame 10 having an upper support plate 11 and a lower support plate 12; an upper opening 13 disposed at the upper support plate 11 for grapes to pass through; a lower opening 14 disposed at the lower support plate 12, located below the upper opening 13; a bag-opening assembly 2 disposed between the upper support plate 11 and the lower support plate 12; and a drawstring assembly 3 disposed at the lower opening 14 and adapted to close the packaging bag. A binding assembly 4 is provided between the binding assembly 3 and the bag opening assembly 2. When the bag opening assembly 2 absorbs and opens the packaging bag, the bag opening is placed between the upper opening 13 and the lower opening 14. Grapes fall into the packaging bag through the upper opening 13. The binding assembly 3 binds the bag opening together with the grape stem. The binding assembly 4 binds the bag opening together with the grape stem with tape and cuts the tape after binding.

[0069] In this solution, the top opening and bottom opening are arranged in a straight line, with a bag opening assembly, a binding assembly, and a mouth-binding assembly arranged sequentially. The bag opening assembly is used to open the bag opening until it is bound. The mouth-binding assembly binds the bag opening along with the grape stem. The binding assembly binds the bag opening. In this way, the bag can be placed on the grape, realizing automated bagging and packaging of grapes.

[0070] Similarly, when packaging grapes for sale, operators only need to lift the stem to package the grapes, thus achieving automated bagging and packaging of grapes.

[0071] like Figures 9-10 As shown, to illustrate the specific structure of the bag-opening assembly, the present invention uses a bag-opening assembly 2 comprising: a first suction cup 21, which is fixed to the upper support plate 11 by a first suction cup frame 22 and located on one side above the lower opening 14; a support plate 23, which is slidably disposed at the bottom of the upper support plate 11 by a first power component; a flipping frame 24, which is rotated and disposed at the bottom of the support plate 23 by a rotating motor 25; and a second suction cup 26, which is fixed to the flipping frame 24 and located on the other side above the lower opening 14. When the second suction cup 26 is reversed to a downward position by the rotating motor 25, it adsorbs the packaging bag. After adsorption is completed, the second suction cup 26 is rotated to be positioned opposite to the first suction cup 21, and the second suction cup 26 is brought close to the first suction cup 21 by the first power component, adsorbing the other side of the packaging bag. The first power component is then reset, opening the bag opening.

[0072] The second suction disc can be driven by the rotating motor to suck the bag downward, and can be driven by the first power assembly to move linearly along the length direction of the frame. The second suction disc rotates to a horizontal state, approaches the first suction disc, and simultaneously performs suction on the packaging bag. Then, the second suction disc and the first suction disc move away, so that the bag opening of the packaging bag is opened, and the grapes can enter.

[0073] As shown in Figures 9-10 In order to illustrate the specific structure of the first power assembly, the first power assembly comprises: an electric push rod 27, the cylinder body of which is fixed at the bottom of the upper support plate 11, and the output end of which is connected with the support plate 23; a sliding block, which is arranged at the top of the support plate 23 and is in sliding connection with the sliding rail on the frame 10;

[0074] The electric push rod works, the output end of the electric push rod is extended, the support plate is driven to slide, and the second suction disc is driven to move linearly.

[0075] As shown in Figure 11 In order to illustrate the specific structure of the mouth closing assembly, the mouth closing assembly 3 comprises: an annular bottom plate 31, which is arranged on the lower support plate 12 and located at the lower opening 14; an annular cover plate 32, which is arranged on the annular bottom plate 31; a plurality of rotors 33, which are equally and spacedly arranged on the annular bottom plate 31; a plurality of arc-shaped blades 34, which are stacked with each other and are fixed on each rotor 33; a synchronous wheel 35, which is controlled to rotate by a motor 36 and is arranged on the annular bottom plate; a synchronous belt (not shown in the figure), which is in meshing connection with each rotor 33 and the synchronous wheel; when the motor 36 is started, the synchronous belt is driven to rotate by the synchronous wheel 35, and each rotor 33 is driven to rotate, so that a plurality of arc-shaped blades 34 are synchronously rotated and extended into the window of the inner circle of the annular cover plate 32, the inner side arcs of the plurality of arc-shaped blades 34 act on the packaging bag, and the packaging bag is closed;

[0076] The structure of the mouth closing assembly is similar to that of the aperture component of an optical camera. The plurality of arc-shaped blades are simultaneously rotated, the inner side arcs act on the bag opening to close the bag opening, and the twisted grape stems are pushed to the middle during the closing process, so that the subsequent binding mechanism can perform the binding work.

[0077] As shown in Figure 11 The bottom plate 31 is further provided with two tensioning wheels 37; the two tensioning wheels 37 are located on both sides of the synchronous wheel 35 and are arranged around the synchronous belt.

[0078] The main synchronous pulley is driven by the motor to drive the rotors to rotate. However, considering that the span of the synchronous belt is large, the length of the synchronous belt is not easy to control, so two tensioning wheels are arranged between the main synchronous pulley and the rotors, so that the effective length of the synchronous belt can be adjusted.

[0079] As Figures 12-13 shown, in order to illustrate the specific structure of the arc-shaped blade and the rotor, the thickness of the arc-shaped blade 34 is 1 / 2 of the thickness of the rotor 33; the arc-shaped blade 34 is arranged obliquely upward from the connection with the rotor 33.

[0080] As Figures 12-13 shown, in order to ensure that the blades always maintain a stacked state during operation, the upper surface of the rotor is an inclined surface, and the thickness of the rotor is 5mm, so that the arc-shaped blades can be stacked with each other during installation, reducing the thickness of the entire device and also reducing the deformation of the arc-shaped blades during rotation due to the extrusion between the arc-shaped blades; as for the blades, the blades are designed to be narrow at the top and wide at the bottom, with a thickness of 2.5mm, which is also to ensure that the arc-shaped blades can always maintain a stacked state during operation, but the blades will inevitably deform during rotation, so the material of the arc-shaped blades is selected to be high-toughness and smooth-surfaced acrylic resin.

[0081] As Figures 14-15 shown, in order to illustrate the specific structure of the bundling assembly, the bundling assembly 4 comprises: a translation assembly adapted to drive the first box body 41 and the second box body 42 to move synchronously along the width direction of the frame 10; a gap 43 is formed between the first box body 41 and the second box body 42 for the bag opening after the bundle opening to pass through; a rotating column 44 is arranged in the second box body 42; an adhesive tape is sleeved on the rotating column 44, and the end portion thereof is placed at the ratchet wheel 46 through the guide column 45; the ratchet wheel 46 is rotatably arranged in the second box body 42; the pawl 47 is rotatably arranged in the first box body 41, the end portion thereof abuts against the notch of the ratchet wheel 46, the first spring 48 is connected between the pawl 47 and the first box body 41; the cutter holder 49 is rotatably arranged in the second box body 42, and is connected with the second box body 42 through the second spring 410, and the cutter 411 is arranged on the cutter holder 49; the profile holder 412 is rotatably arranged in the first box body 41, and is connected with the first box body 41 through the third spring 413, and the end portion thereof is adapted to be supported by the extension segment 414 of the cutter holder 49; when the bag opening after the bundle opening passes through the gap 43, the pawl 47 is forced to rotate to embed the adhesive tape in the notch, and after winding around the bag opening for one turn, the adhesive tape passes through the cutter holder 49, the cutter holder 49 is forced to rotate to rotate and cut off the adhesive tape;

[0082] As Figure 16The ratchet wheel and the pawl are matched in shape, the pawl is perfectly engaged in the groove of the ratchet wheel as much as possible to ensure that the adhesive tape is fully adhered; the front ends of the profile frame and the cutter frame need to be tightly pinched, so the length of the profile frame is longer than that of the cutter frame, and the front end of the profile frame is placed on the support section of the cutter frame; the size of the cutter frame needs to be ensured to be able to smoothly cut the adhesive tape after being forced to rotate a certain angle, the adhesive tape is installed on the rotating column of the second box body during installation, the adhesive tape is wound around the ratchet wheel through the guide column, the pawl embeds the adhesive tape in the groove of the ratchet wheel and adheres the adhesive tape to the surface for taking out the adhesive tape, the first box body and the second box body have a gap, and the gap is rounded at the inlet to facilitate the bag opening to enter the channel; during bundling, the bundled bag opening passes through the gap, the pawl is pushed to move downward and the adhesive tape is pulled out to surround the bag opening for one turn, after the adhesive tape is wound, the pawl will re-engage with the ratchet wheel with the excess adhesive tape; then the bag opening continues to advance, the cutter on the cutter frame cuts the adhesive tape, at the same time, the profile frame and the cutter frame pinch the cut adhesive tape; after the bundling is completed, each part returns to the initial position through the spring, the pawl re-embeds the adhesive tape in the groove of the ratchet wheel and adheres the adhesive tape to the surface, and the cycle is completed.

[0083] As Figure 15 In order to illustrate the specific structure of the translation assembly, the translation assembly comprises: a main transmission shaft 51 arranged along the length direction of the frame body; a first transmission shaft 52 rotatably arranged on one side of the lower opening 14 along the width direction of the frame body and connected with the main transmission shaft 51 through a bevel gear pair; a second transmission shaft 53 rotatably arranged on the other side of the lower opening 14 along the width direction of the frame body and connected with the main transmission shaft 51 through a bevel gear pair; a driving motor 54 connected with the main transmission shaft 51 through a bevel gear pair; a first connecting rod 55 connected with the first box body 41 and connected with the first transmission shaft 52 through a screw rod pair; a second connecting rod 56 connected with the second box body 42 and connected with the second transmission shaft 53 through a screw rod pair; when the driving motor 54 is started, the main transmission shaft 51 is driven to rotate, the main transmission shaft 51 drives the first transmission shaft 52 and the second transmission shaft 53 to rotate through the bevel gear pair; the first transmission shaft 52 and the second transmission shaft 53 drive the first connecting rod 55 and the second connecting rod 56 to move along the width direction of the frame body 10 through the corresponding screw rod pairs, and then drive the first box body 41 and the second box body 42 to move along the width direction of the frame body 10.

[0084] In this way, through the rotation of the driving motor, the synchronous movement of the first box body and the second box body along the width direction of the frame body can be realized.
