Description

Technical Field

[0001] This invention relates to the field of packaging technology, specifically to a compact labeling machine for paper bowls in bags. Background Technology

[0002] Bagged paper bowls refer to the production of multiple paper bowls packaged in soft plastic bags (such as PE / PP).

[0003] For packaging bags such as soft plastic bags, because they are flexible and easily deformed, they are usually labeled before packaging. After packaging paper bowls, the overall shape of the packaging bag is irregular.

[0004] The labels affixed before packaging are generally generic labels, which contain information that is required by regulations or remains unchanged over time, such as product name, ingredients, and manufacturer information.

[0005] For immediate-release labels, these labels contain mandatory information that cannot be covered by general labels, such as production date and batch number. They are generally affixed after packaging is complete.

[0006] (1) Because the overall shape of the packaging bag is irregular after packaging, there is no regular support surface during the labeling process, which affects the firmness of the labeling;

[0007] (2) In order to ensure the firmness of the label, if a reinforcement operation such as pressing is performed after the label is applied, it may cause compression to the soft material such as the paper bowl, affecting the appearance of the product when it leaves the factory.

[0008] (3) The labeling process generally constitutes an independent production line, which occupies additional production space to a certain extent. Furthermore, for real-time labels containing real-time information, if an independent production line is used for labeling, when the batch of products corresponding to the series of real-time information may be destroyed due to quality problems, the real-time labels corresponding to the batch of products need to be removed simultaneously, which may cause information confusion and affect the overall production rhythm of the production line to a certain extent.

[0009] Therefore, we propose a compact labeling machine for paper bowls in bags. Summary of the Invention

[0010] [Technical problems solved]

[0011] To address the shortcomings of existing technologies, this invention provides a compact bagged paper bowl labeling machine, which has advantages such as labeling support, process integration, and high compactness, and can effectively solve the problems in the background technology.

[0012] [Technical Solution]

[0013] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a compact bagged paper bowl labeling machine, including a labeling mechanism and an adsorption mechanism for adsorbing and pulling apart the container, and also including a support assembly, which includes at least two parts. In the combined state, the at least two parts are used to support the interior of the container during the labeling process, and are configured to move towards or away from each other, so as to open the container when the at least two parts move to contact the container.

[0014] Preferably, in this embodiment, the labeling mechanism can be a pressure-type or a vacuum adsorption type, which are optional setups made by those skilled in the art based on existing technology and actual implementation conditions.

[0015] Preferably, the adsorption mechanism is an adsorption mechanism such as a vacuum suction cup for adsorbing the contents. The aim is to use the vacuum suction cups located on both sides of the contents to generate negative pressure to pull the contents apart. This is an optional setup for actual implementation by those skilled in the art, so it will not be described in detail in this embodiment, nor will it be considered as a further limitation on the technical features of the present invention.

[0016] Preferably, in this embodiment, the support component includes at least two parts that can be of any structural shape, so that the two parts can form a complete and relatively flat surface after being combined, thereby supporting the labeling process of the container.

[0017] Preferably, the two parts on the support assembly are configured to move towards each other or away from each other, which means that the movement is controlled by an external drive mechanism or manually. In this embodiment, it can be a drive mechanism that moves two lead screw pairs by a lead screw, or a drive mechanism such as an electric slide table, which aims to achieve the function of moving the two parts on the support assembly towards each other or away from each other. This is an optional configuration made by those skilled in the art for actual implementation, so it will not be described in detail in this embodiment, nor is it intended to further limit the technical features of the present invention.

[0018] Preferably, in this embodiment, the drive mechanism is configured to be movable in at least one dimension, i.e., at least vertical or horizontal, and can also rotate. However, it is controlled by an external robotic arm and is intended to move the support assembly into the interior of the container for support or expansion.

[0019] Preferably, without changing the connection relationship between the support component and the drive mechanism, the position of the support component can be offset relative to the drive mechanism, such as... Figure 2 As shown in the diagram, in this state, the product can be unloaded at the location indicated by the hollow arrow to ensure a smooth product transport path.

[0020] Preferably, the support assembly includes at least two arm-shaped members as the two parts, and the support assembly also includes at least two smoothing members that can move towards or away from each other, for applying force to the interior of the container during the movement of the smoothing members after the container is opened.

[0021] Preferably, the two smoothing parts can move towards or away from each other, which means that they are controlled by an external drive mechanism, such as an electric slide table or a drive mechanism like a lead screw + lead screw pair or a screw + screw pair.

[0022] Preferably, the arm-shaped or smoothing member can be cylindrical or square, and the part that may come into contact with the container is preferably made of curved surface to reduce friction on the container during contact.

[0023] Preferably, the smoothing component can be a roller-like structure.

[0024] Preferably, the smoothing member is provided with a force-receiving part, and a slide rail is provided in cooperation with the force-receiving part. The force-receiving part can only move in one direction on the slide rail. This direction is configured to be in the same direction as the movable direction of the smoothing member, and the slide rail can move in a direction perpendicular to the movable direction of the smoothing member.

[0025] Preferably, the force-bearing part and the corresponding smoothing part are rigidly connected, which can be a fixed connection or a direct opening on the smoothing part.

[0026] Preferably, the labeling machine further includes a drive mechanism, which includes a gear and two racks that mesh with the gear and are symmetrical about the gear. The racks are connected to the arm-shaped object or smoothing component and are used to drive the corresponding arm-shaped object or smoothing component to move during the movement. The drive mechanism consists of two racks and a gear.

[0027] Preferably, the gear is fixed so that it can only rotate and not rotatable, and the rack and the corresponding arm-shaped object or smoothing part are rigidly connected, which can be a fixed connection.

[0028] Preferably, when the drive mechanism is provided in at least two sets, the gears in the two sets of drive mechanisms are arranged in the same axial direction, and a drive shaft is provided between the two gears. The drive shaft is configured to engage with the two gears, and can only engage with one of the gears at any given time.

[0029] Preferably, the drive shaft is configured to engage with the two gears, and the fact that it can only engage with one gear at a time means that when the drive shaft engages with one gear, it disengages from the other gear. In other words, the drive shaft can only drive the gear it engages with to rotate, and the gears it disengages from are in a mutual rotational relationship.

[0030] Preferably, the smoothing component is connected to the drive shaft, and is used to drive the smoothing component to move synchronously via a slide rail during the movement of the drive shaft.

[0031] Preferably, in this embodiment, the smoothing component is connected to the drive shaft or the drive end of a moving drive component that drives the drive shaft via a slide rail, forming a rigid connection, which can be a fixed connection.

[0032] Preferably, a rotary drive component is connected to the drive shaft. The rotary drive component is any type of rotary drive component that can drive the drive shaft to rotate, such as a motor or a motor + reducer. Those skilled in the art can choose to install it according to the actual implementation situation.

[0033] Preferably, when the drive shaft needs to move while satisfying the rotational drive conditions, such as... Figure 7 In the structural state shown, the drive shaft is connected to the rotating drive component through a set of relatively perpendicular helical gears, thereby changing the direction of the drive path of the drive shaft. The drive shaft can be connected to a moving drive component in its axial direction. The moving drive component can be an electric push rod, or a fluid-type straight cylinder actuator such as a cylinder, any of which can drive the drive shaft to move in its axial direction.

[0034] Preferably, the drive shaft includes a key shaft one, with key shaft two rotatably connected to both ends of the key shaft one. One end of the key shaft one passes through the key shaft two corresponding to that end. The key shaft one is configured to be axially movable and rotatable.

[0035] Preferably, the key shaft one has one end passing through the corresponding key shaft two, which means that a key shaft three is provided on the key shaft one. The key shaft three passes through the key shaft two to the outside and forms a transmission connection with the external rotation drive component and movement drive component through the key shaft three.

[0036] Preferably, the first key shaft is rotatably connected to the second key shaft located at both ends by two rotatable connectors. In this embodiment, the rotatable connectors can be bearings.

[0037] Preferably, the drive mechanism further includes a fixing member, and the drive shaft is configured such that when the first key shaft engages with one of the gears, the second key shaft that engages with the other gear simultaneously engages with the fixing member and cannot rotate.

[0038] Preferably, the fixing member is an external fixing frame, and the entire drive mechanism is connected to an external control device such as a robotic arm through the fixing member.

[0039] Preferably, in this embodiment, the gear is rotatably connected to the fixed member and is not movable.

[0040] Preferably, two fixing parts are provided on the fixing member, and the fixing parts are keyways, which are used to form a key engagement with the key shaft on the drive shaft.

[0041] [Beneficial Effects]

[0042] Compared with the prior art, the present invention provides a compact labeling machine for bagged paper bowls, which has the following advantages:

[0043] This compact bagged paper bowl labeling machine, through its set support component, extends into the interior of the container when the two parts of the support component are combined, thus supporting the labeling area on the container. After labeling is completed, the two parts of the support component are moved until they are both in contact with the container, thereby expanding the container. In this way, the labeling action for soft materials such as containers is integrated into the product packaging process. On the one hand, it can ensure the flatness of the labeling on the container to the greatest extent, and on the other hand, it can adapt to the dynamic needs of real-time label application.

[0064] To make the technical means, creative features, achieved objectives, and functional effects of this invention readily understandable, the invention will be further described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0065] Example 1

[0066] To address the shortcomings of existing technologies, such as Figures 1-3As shown, the present invention provides a compact bagged paper bowl labeling machine, including a labeling mechanism 4 and an adsorption mechanism 3 for adsorbing and pulling apart a container 001, and also includes a support assembly 1. The support assembly 1 includes at least two parts, which, in a combined state, are used to support the interior of the container 001 during the labeling process, and are configured to move towards or away from each other, so as to open the container 001 when the at least two parts move to contact the container 001.

[0067] In this embodiment, the labeling mechanism 4 can be a pressure-adhesive type or a vacuum adsorption type, which are optional installations made by those skilled in the art based on the actual implementation situation and with reference to the prior art.

[0068] The adsorption mechanism 3 mainly adopts an adsorption mechanism such as a vacuum suction cup for adsorbing the container 001. It aims to use the vacuum suction cups located on both sides of the container 001 to generate negative pressure suction to pull the container 001 apart. This is an optional setup made by those skilled in the art for actual implementation, so it will not be described in detail in this embodiment, nor will it be regarded as a further limitation on the technical features of the present invention.

[0069] In this embodiment, the support component 1 includes at least two parts that can be of any structural shape, with the aim that the two parts can form a complete and relatively flat surface after being combined, so that the surface can support the labeling process of the container 001.

[0070] The configuration of the two parts on the support assembly 1 to move towards each other / away from each other refers to control by an external drive mechanism or manual control. In this embodiment, it can be a drive mechanism that drives two lead screw pairs to move by a lead screw, or a drive mechanism such as an electric slide table, which aims to achieve the function of driving the two parts on the support assembly 1 to move towards each other / away from each other. This is an optional configuration made by those skilled in the art for actual implementation, so it will not be described in detail in this embodiment, nor will it be regarded as a further limitation on the technical features of the present invention.

[0071] In this embodiment, the drive mechanism 2 is configured to move in at least one dimension, that is, to move at least vertically or laterally, and to rotate at the same time. However, it is controlled by an external robotic arm and is intended to move the support assembly 1 into the interior of the container 001 for support or expansion.

[0072] It should be noted that in this embodiment, the container 001 mainly refers to a soft packaging material such as a packaging bag, used to package and sell products such as paper bowls. Furthermore, those skilled in the art will understand that the present invention is not limited to packaging operations such as labeling paper bowls. For example, it can be paper cups, etc., and its packaging process is similar to any product known and understood by those skilled in the art, such as paper bowls. In this embodiment, paper bowls are mainly used as an example.

[0073] During the labeling process of the paper bowl packaging, the container 001 is transported to the operable space of the adsorption mechanism 3, or the adsorption mechanism 3 moves to a position where it can adsorb the adsorption mechanism 3, and the adsorption mechanism 3 is activated. The adsorption mechanisms 3 are distributed on both sides of the container 001 to adsorb the two sides of the container 001. Then the adsorption mechanisms 3 distributed on both sides of the container 001 move apart to form a pulling action on the container 001.

[0074] After container 001 is opened, as follows Figure 1 In the structural state shown, a support component 1 is inserted inside the container 001. The part of the support component 1 inside the container 001 corresponds to the part where the label is pre-labeled on the outside of the container 001. Based on this support component 1, the labeling mechanism 4 with the label is moved outside the container 001, so that the labeling mechanism 4 acts on the outside of the container 001 to achieve labeling.

[0075] After the container 001 is labeled, the two parts on the support assembly 1 are moved apart by the drive mechanism 2 until the two parts are in full contact with the container 001, thus forming a complete opening action of the container 001. Then, based on this opening action, the paper bowl can be put into the container 001. For example, the paper bowl can be transported to the top of the container 001 by a conveying device, and the container 001 is longitudinally opened by a mouth opener above the container 001 so that the paper bowl can be put in.

[0076] It is worth mentioning that, through the set support component 1, with the two parts of the support component 1 combined, the support component 1 is inserted into the interior of the container 001 to provide support for the labeling part on the container 001. After the labeling is completed, the two parts of the support component 1 are moved until they are in contact with the container 001 to expand the container 001. In this way, the labeling action for soft materials such as the container 001 is integrated into the product packaging process. On the one hand, it can ensure that the labeling of the container 001 is as flat as possible. On the other hand, it enables the labeling machine to adapt to the dynamic needs of real-time label application.

[0077] As a preferred embodiment, such as Figure 2As shown, the positions of the support component 1 and the drive mechanism 2 can be offset relative to the drive mechanism 2 without changing the connection relationship between them. For example... Figure 2 As shown in the diagram, in this state, the product can be unloaded at the location indicated by the hollow arrow to ensure a smooth product transport path.

[0078] As a preferred embodiment, such as Figure 4 , 5 As shown, the support assembly 1 also includes a fitting arm 13 that fits into the structure of the arm 11. The arm 11 and the fitting arm 13 form a regular shape to effectively reduce friction caused by unnecessary contact that may occur during the insertion of the support assembly 1 into the container 001.

[0079]

Example 2

[0080] In the above embodiment one, the labeling operation of the container 001 is carried out during the pre-packaging process of opening the container 001, thereby integrating the labeling process into the packaging process of the paper bowl.

[0081] Considering that the container 001 is made of a soft material, and in order to make the labeling machine adaptable to the existing compact requirements (small body design, small footprint, suitable for installation on production lines or workstations with limited space), the selection of the labeling machine in this embodiment is mainly based on the labeling machine with the fewest dimensional operating directions, such as a unidirectional moving pressing labeling machine, which uses a direct pressing method to complete the labeling operation of the container 001.

[0082] However, labeling machines that only have a pressing method lack a spreading action, which limits the adhesion of labels applied to soft materials such as container 001. Therefore, to further improve the adhesion of labels applied to container 001 while ensuring a compact overall structure, this embodiment is proposed based on the above-described embodiment one:

[0083] Specifically, such as Figure 4 As shown, the support assembly 1 for a compact bagged paper bowl labeling machine includes at least two arm-shaped parts 11, which are two parts. The support assembly 1 also includes at least two smoothing parts 12 that can move towards or away from each other, which are used to apply force to the interior of the container 001 during the movement of the smoothing parts 12 after the container 001 is opened.

[0084] The ability of the two smoothing parts 12 to move toward or away from each other is controlled by an external drive mechanism, which can be an electric slide table or a drive mechanism such as a lead screw + lead screw pair or a screw + screw pair.

[0085] The arm-shaped part 11 or the smoothing part 12 can be cylindrical or square, and the part that may come into contact with the container 001 is preferably set as an arc surface to reduce the friction on the container 001 during the contact process.

[0086] The smoothing component 12 can be a roller-like structure.

[0087] It should be noted that this invention is a compact bagged paper bowl labeling machine. Through the provided support component 1, during the pre-labeling process of the container 001, i.e., during the pre-expansion process of the container 001, the initial structural state of the support component 1 is as follows: Figure 3 As shown, the support component 1 is inserted into the container 001 in a whole state to provide support for the labeling process of the container 001. It is mainly composed of two arm-shaped parts 11 on the support component 1.

[0088] After labeling the container 001, it is necessary to expand the container 001. This is done by moving two arm-shaped objects 11 apart inside the container 001 until both arm-shaped objects 11 are in full contact with the container 001, thereby achieving unidirectional expansion of the container 001. In this state, the container 001 is expanded into a taut state.

[0089] Then, with the container 001 taut and the labeling mechanism 4 located outside the container 001 not retracted, the labeling mechanism 4 provides support to the outside of the container 001. At this time, two smoothing parts 12 move apart inside the container 001. With the labeling mechanism 4 providing support to the outside of the container 001, the two smoothing parts 12 move apart inside the container 001, and the two smoothing parts 12 act on the inner surface of the container 001 during the movement, thereby forming a smoothing action on the inner surface of the container 001.

[0090] It is worth mentioning that after the container 001 is fully opened, the smoothing component 12 is moved inside the container 001 to form a smoothing action applied after labeling the container 001. Since the support component 1 has a smoothing action, a relatively simple vertical pressure labeling mechanism 4 can be used. Because the operation of the labeling mechanism 4 is simple, the labeling mechanism 4 is more compact to a certain extent, which is conducive to improving the overall integration of the production line and is more suitable for integrating the labeling process into the packaging process.

[0091] As a preferred embodiment, and as Figure 4As shown, when the smoothing member 12 is present, the smoothing member 12 is located inside the enclosing structure formed by the arm-shaped member 11 and the fitting arm 13. In this way, when the support component 1 is pre-inserted into the container 001, friction caused by the smoothing member 12 being exposed to the outside and potentially having unnecessary contact with the container 001 can be effectively avoided.

[0092]

Example 3

[0093] In the above-described embodiment two, since a smoothing action is added after the spreading action, and there is a need to control both sets of arm-shaped components 11 and smoothing components 12, the single-motor system only requires one set of control logic. Considering that the difference between the dual-motor system and the single-motor system is that the dual-motor system usually requires complex coordination control algorithms (such as speed synchronization, load distribution, braking anti-slip, etc.), in order to reduce the overall manufacturing cost of the device and simplify the control mechanism of the two sets of arm-shaped components 11 and smoothing components 12, this embodiment is proposed based on the above-described embodiment two:

[0094] Specifically, such as Figure 5 , 7 As shown, the driving mechanism 2 for a compact bagged paper bowl labeling machine is also included. The labeling machine further includes a driving mechanism 2, which includes a gear 22. Two racks 21 mesh with the gear 22 and are symmetrical about the gear 22. The racks 21 are connected to the arm-shaped object 11 or the smoothing part 12 and are used to drive the corresponding arm-shaped object 11 or the smoothing part 12 to move during the movement. The driving mechanism 2 is composed of two racks 21 and a gear 22.

[0095] When the drive mechanism 2 is provided with at least two sets, the gears 22 in the two sets of drive mechanisms 2 are arranged on the same axial direction, and a drive shaft 23 is provided between the two gears 22. The drive shaft 23 is configured to engage with the two gears 22, and can only engage with one of the gears 22 at any given time.

[0096] Among them, the gear 22 is fixed so that it can only rotate and not rotate, and the rack 21 is rigidly connected to the corresponding arm 11 or smoothing part 12, which can be a fixed connection.

[0097] The drive shaft 23 is configured to engage with the two gears 22, and can only engage with one of the gears 22 at a time. This means that when the drive shaft 23 engages with one of the gears 22, it disengages from the other gear 22. In other words, the drive shaft 23 can only drive the gear 22 it engages with to rotate, and the gears 22 it disengages from are in a mutual rotational relationship.

[0098] It should be noted that this invention is a compact bagged paper bowl labeling machine. In the above embodiment, the drive mechanism 2 first controls the movement of the arm-shaped object 11. After the arm-shaped object 11 effectively expands the container 001, the smoothing component 12 smooths the container 001. That is, during the packaging and labeling process:

[0099] In practical implementation, if it is necessary to control the movement of either the arm-shaped object 11 or the smoothing component 12, in this embodiment, taking the movement control of the arm-shaped object 11 as an example, the drive shaft 23 is moved to engage with the gear 22 attached to the arm-shaped object 11 rather than with the gear 22 attached to the smoothing component 12. That is, the drive shaft 23 can drive the gear 22 attached to the arm-shaped object 11 to rotate, but cannot drive the gear 22 attached to the smoothing component 12 to rotate.

[0100] In this state, the drive shaft 23 is driven to rotate by rotating the drive member 24. During the rotation of the drive shaft 23, the gear 22 that engages with it is driven to rotate. During the rotation of the gear 22, the two racks 21 that mesh with it are driven to move apart or towards each other, thereby realizing the movement control of the arm-shaped object 11 or the smoothing member 12 connected to the rack 21.

[0101] It is worth mentioning that in this embodiment, the two sets of arm-shaped parts 11 and the smoothing parts 12 on the support component 1 are controlled in batches by the drive mechanism 2. Compared with the dual-motor system, the control logic of the single-motor system is simpler, the operation and maintenance are more convenient in actual implementation, and the cost is lower, making it suitable for mass application on the production line.

[0102]

Example 4

[0103] In the above embodiment three, since the two sets of racks 21 and gears 22 are controlled in batches by a single set of rotation drive 24 and movement drive 25, this embodiment is proposed to ensure that the other set of racks 21 and gears 22 can remain sufficiently stable during the control of one set of racks 21 and gears 22:

[0104] Specifically, such as Figure 5 , 7 As shown in Figure 8, the drive mechanism 2 for a compact bagged paper bowl labeling machine also includes a fixing member 26. The drive shaft 23 is configured such that when the key shaft 231 engages with its gear 22, the key shaft 232 that engages with the other gear 22 simultaneously engages with the fixing member 26 and cannot rotate.

[0105] Among them, the fixing component 26 is an external fixing frame, and the entire drive mechanism 2 is connected to an external control device such as a robotic arm through the fixing component 26;

[0106] In this embodiment, gear 22 is rotatably connected to fixed member 26 and cannot be moved;

[0107] Two fixing parts 261 are provided on the fixing member 26. The fixing parts 261 are keyways, which are used to form a key engagement with the key shaft 232 on the drive shaft 23.

[0108] Furthermore, such as Figure 9 As shown, the drive shaft 23 for a compact bagged paper bowl labeling machine includes a key shaft 231, and key shafts 232 are rotatably connected to both ends of the key shaft 231. One end of the key shaft 231 passes through the key shaft 232 corresponding to that end. The key shaft 231 is configured to be axially movable and rotatable.

[0109] Wherein, the key shaft 231 has one end passing through the key shaft 232 corresponding to that end, which means that a key shaft 2311 is provided on the key shaft 231. The key shaft 2311 is passed through the key shaft 232 to the outside, and is connected to the external rotation drive 24 and movement drive 25 through the key shaft 2311.

[0110] In a preferred embodiment, key shaft 231 is rotatably connected to key shaft 232 located at both ends by two rotatable connectors 233. In this embodiment, the rotatable connectors 233 can be bearings.

[0111] It should be noted that the present invention is a compact bagged paper bowl labeling machine. Through the set drive mechanism 2, in the process of batch control of the two sets of arm-shaped objects 11 and smoothing parts 12, the key shaft 231 is moved between the two gears 22. When the key shaft 231 moves to engage with one of the gears 22, rotating the key shaft 231 can drive the gear 22 to rotate, so as to realize the movement control of the arm-shaped objects 11 or smoothing parts 12 attached thereto.

[0112] During this process, another gear 22 engages with the second key shaft 232 on the drive shaft 23. Since the second key shaft 232 and the first key shaft 231 are rotatably connected, the rotation of the second key shaft 232 will not be disturbed when the first key shaft 231 drives the gear 22 it engages with to rotate.

[0113] In addition, such as Figure 10 In the structural state shown, when key shaft 231 engages with one of its gears 22, key shaft 232, which engages with another gear 22, is simultaneously engaged with the outside. In this embodiment, it is a fixing part 261 engaged with the fixing member 26. When key shaft 232 engages with the fixing member 26 and one of its gears 22, the rotation of the gear 22 is restricted by the fixing member 26 and thus will not rotate on its own, thereby ensuring its own stability.

[0114] Example 5

[0115] In the above embodiment 2, since the spreading action of the container 001 is performed after the spreading action of the container 001, during the spreading process of the container 001, the container 001 should only contact the arm 11 that is spreading. The requirement for spreading the container 001 is that the smoothing member 12 needs to protrude from the arm 11, that is, the smoothing member 12 needs to contact the container 001 further than the arm 11, so that the smoothing member 12 can effectively apply force to the container 001 during the movement of the smoothing member 12.

[0116] As described above, if the smoothing component 12 partially contacts the container 001 during the process of spreading the container 001, meaning that the container 001 experiences force at least at three points during the spreading process, the spreading of the container 001 will be insufficient, resulting in a lack of tightness in the spread container 001 and affecting the effectiveness of subsequent smoothing operations. Therefore, this embodiment is proposed:

[0117] Specifically, such as Figure 6 As shown, the smoothing part 12 for a compact bagged paper bowl labeling machine has a force-receiving part 121 and a slide rail 122 that cooperates with the force-receiving part 121. The force-receiving part 121 can only move in one direction on the slide rail 122. This direction is configured to be the same as the movable direction of the smoothing part 12, and the slide rail 122 can move in a direction perpendicular to the movable direction of the smoothing part 12.

[0118] The force-bearing part 121 and the corresponding smoothing part 12 are rigidly connected, which can be a fixed connection or directly opened on the smoothing part 12.

[0119] In this embodiment, a moving drive member 25 may be provided on the slide rail 122 to drive the slide rail 122 to move in a direction perpendicular to the movable direction of the smoothing member 12.

[0120] It should be noted that this invention is a compact bagged paper bowl labeling machine. Through the provided smoothing component 12, during the process of opening the container 001, the smoothing component 12 is in a non-extended state, such as... Figure 10 The structure shown is such that only the arm-shaped part 11 is in contact with the container 001. With this structure, the container 001 can be opened up without being disturbed by the smoothing part 12.

[0121] In this embodiment, the direction of controlling the extension state of the smoothing member 12 is vertical, and the direction of moving the smoothing member 12 toward the arm-shaped object 11 is horizontal.

[0122] Then, after the container 001 has been effectively opened, if it is necessary to smooth the container 001, the smoothing component 12 is moved vertically so that it extends outward relative to the arm-shaped component 11. Figure 10 The structure shown is in a state where the smoothing member 12 extends out and contacts the container 001. At this time, the smoothing member 12 is moved laterally to smooth the container 001.

[0123] Furthermore, such as Figure 7 As shown, the smoothing component 12 used in the compact bagged paper bowl labeling machine is connected to the drive shaft 23 and is used to drive the smoothing component 12 to move synchronously through the slide rail 122 during the movement of the drive shaft 23.

[0124] In this embodiment, the smoothing component 12 is connected to the drive shaft 23 or the drive end of the moving drive component 25 that drives the drive shaft 23 to move via the slide rail 122. It is a rigid connection and can be a fixed connection.

[0125] A rotation drive component 24 is connected to the drive shaft 23. The rotation drive component 24 is any type of rotation drive component that can drive the drive shaft 23 to rotate, such as a motor or a motor + reducer. Those skilled in the art can choose to install it according to the actual implementation situation.

[0126] When the drive shaft 23 needs to move while satisfying the rotation drive conditions, such as Figure 7 In the structural state shown, the drive shaft 23 is connected to the rotating drive member 24 through a set of relatively perpendicular helical gears, thereby changing the direction of the drive path of the drive shaft 23. The drive shaft 23 can be connected to a movable drive member 25 in its axial direction. The movable drive member 25 can be an electric push rod or a fluid-type straight cylinder actuator such as a cylinder, any of which can drive the drive shaft 23 to move in its axial direction.

[0127] It should be noted that this invention is a compact labeling machine for bagged paper bowls. In this embodiment, the smoothing component 12, as shown... Figure 10 In the structural state shown, after the movement control of the arm-shaped object 11 is completed, that is, after the arm-shaped object 11 effectively expands the container 001, the movement control of the smoothing part 12 is required.

[0128] That is, the drive shaft 23 needs to be moved to switch the movement control of the arm 11 and the smoothing part 12. During the movement of the drive shaft 23, in this embodiment, the movement of the drive shaft 23 drives the slide rail 122 to move. During the movement of the slide rail 122, force is applied to the slide rail 122 connected to the smoothing part 12 to drive the smoothing part 12 to move vertically and extend.

[0129] After the smoothing component 12 extends, it is necessary to control the smoothing component 12 to move laterally. That is, the smoothing component 12 moves laterally relative to the slide rail 122 based on the force-bearing part 121 to complete the smoothing action.

[0130] It is worth mentioning that in this embodiment, the extension / retraction control of the smoothing component 12 is integrated into the movement control of the drive shaft 23, without the need to install a separate control device for the smoothing component 12. This not only ensures that the labeling machine has a compact overall structure and complete functions, but also further reduces the overall setup and maintenance costs of the production line.

[0131] In summary, the basic working principle of this invention is as follows:

[0132] In the process of packaging products such as paper bowls, the container 001 is first pulled open by the adsorption mechanism 3, and then the support component 1 is inserted into the container 001. The support component 1 is in the combined state at this time. In this state, the labeling mechanism 4 is moved to the part corresponding to the support component 1 on the outside of the container 001, so that the labeling mechanism 4 acts on the container 001 to complete the basic labeling.

[0133] Then the drive mechanism 2 drives the two arm-shaped parts 11 on the support assembly 1 to separate until the two arm-shaped parts 11 are in full contact with the container 001, so as to complete the opening of the container 001.

[0134] Subsequently, with the container 001 open, the two smoothing parts 12 are moved by the drive mechanism 2. During the movement, the two smoothing parts 12 apply force to the container 001 from inside. This action is completed without the labeling mechanism 4 located outside the container 001 being removed, thus constituting a smoothing action on the container 001 after labeling.

[0135] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
