Description

Technical Field

[0001] This utility model relates to the field of bag making technology, and in particular to a handle transfer device for bag making equipment and bag making equipment. Background Technology

[0002] In the automated production process of bag making equipment, the handle piece is a crucial component of the packaging bag. The precise and stable transfer of the handle piece is a key process for ensuring the quality of bag forming and production efficiency. Currently, the handle piece transfer structures in conventional bag making equipment on the market are mostly simple pushing structures, free-fall feeding structures, or simple flat belt conveyor structures. These conveyor structures are simple in design, relying solely on the material's own gravity or the slight friction of a regular belt to complete the feeding. They are simple in structure and single in function, mainly used for conveying and shifting the handle piece.

[0003] However, in existing technologies, the handle conveying structure relies solely on the friction between surfaces to complete the conveying process. This can easily lead to handle pieces shifting, slipping, warping, or even falling off. It also makes it impossible to accurately align the handle with the fixed part of the bag body material, greatly reducing the stability of the handle transfer and easily causing defective or waste packaging bags. Furthermore, existing bag making equipment typically uses a low-speed conveying and manual correction method, which not only significantly reduces the efficiency of handle transfer and cannot adapt to the high-speed automated bag making production rate, but also increases the cost of manual intervention and equipment maintenance. Utility Model Content

[0004] The purpose of this invention is to solve the technical problem that the existing handle conveying structure relies solely on the friction between surfaces to complete the conveying, which easily leads to handle offset, slippage, warping, or even detachment, greatly reducing the stability of handle transfer and also affecting the transfer rate of handle.

[0005] To solve the above-mentioned technical problems, the present invention discloses a handle piece transfer device for bag making equipment, including a conveying component and a pressing component.

[0006] The conveying component has a conveying channel and a conveying section extending along the conveying direction. The handle piece enters the conveying channel from the inlet end of the conveying component and is conveyed by the conveying section, and is output from the outlet end of the conveying component. The outlet end faces the handle fixing part of the sheet material being transported on the bag making equipment. The conveying section has an engaging force that engages with the handle piece.

[0007] The pressing component is located beside the inlet end of the conveying component. The pressing component has a movable pressing part that can press the handle piece that enters the conveying channel from the inlet end in sequence, so that the handle piece engages with the conveying component.

[0008] The above technical solution includes a conveying channel and a conveying section with engagement force. The handle piece enters from the inlet end and engages with the conveying section, then is conveyed along the conveying direction to the outlet end and output to the handle fixing part. The engagement force of the conveying section ensures reliable contact between the handle piece and the conveying section during conveying. Compared to existing structures that rely solely on surface friction, this reduces the handle piece's deviation and slippage during conveying. Furthermore, a pressing component is located beside the inlet end. This pressing component presses the handle piece entering the conveying channel, ensuring full engagement between the handle piece and the conveying section. This helps prevent the handle piece from shifting or falling off due to poor engagement when entering the conveying channel.

[0009] Therefore, the conveying and pressing components of this handle transfer device work together to improve the stability and continuity of handle transfer, from the pressing engagement at the inlet to the continuous engagement during the conveying process. Furthermore, the pressing component allows the handle to enter the conveying channel at a high speed and quickly engage with the conveyor, facilitating adaptation to high-speed automated bag-making production rates.

[0010] The present invention also discloses a handle piece transfer device for bag making equipment, wherein a vacuum chamber is provided on the side of the conveying channel, and the conveying part has an adsorption part communicating with the vacuum chamber.

[0011] The conveying unit engages the handle piece located in the conveying channel with the adsorption force of the adsorption unit.

[0012] Using the above technical solution, a negative pressure environment is created in the vacuum chamber. This negative pressure is applied to the handle pieces within the conveying channel via the adsorption unit, allowing the conveying unit to engage with the handle pieces through adsorption. Adsorption provides a more reliable connection, further reducing the risk of handle pieces shifting, slipping, or warping during transport. Furthermore, the structural configuration of the adsorption unit and vacuum chamber can accommodate handle pieces of different specifications and materials. By adjusting the negative pressure, the adsorption force can be matched to the weight and area of ​​the handle pieces, thus expanding the applicability of the handle piece transfer device.

[0013] In addition, the adsorption force acts in a gentle manner, making it less likely to cause indentations or damage to the surface of the handle, thus helping to maintain the surface quality of the handle.

[0014] The present invention also discloses a handle piece transfer device for a bag making equipment. The conveying component includes a conveyor belt assembly disposed on the frame of the bag making equipment. One side of the conveyor belt assembly is located beside the conveying channel and extends along the conveying direction to form a conveying section. Multiple adsorption sections are arranged at intervals on the conveyor belt.

[0015] Furthermore, the vacuum chamber is enclosed on one side of the belt, away from the conveying channel.

[0016] Using the above technical solution, the conveyor belt assembly provides a continuously operating conveying surface. One side of the belt extends along the conveying direction to form the conveying section, providing a continuous conveying path for the handle pieces. Multiple adsorption sections spaced apart on the belt form an adsorption force when passing through the area covered by the vacuum chamber, ensuring that the handle pieces are continuously adsorbed throughout the conveying process, thus helping to maintain the stability of the conveying process. The vacuum chamber is located on the side of the belt away from the conveying channel, so that the negative pressure area corresponds to the position of the adsorption sections, resulting in a compact structural layout that helps reduce the overall size of the device. In addition, the belt conveyor system operates smoothly and with low noise, making it suitable for continuous high-speed operation and facilitating adaptation to high-speed automated bag-making production rates.

[0017] The present invention also discloses a handle piece transfer device for a bag making equipment. The pressing component includes a pressing body disposed on the frame of the bag making equipment and capable of swinging about an axis extending in a vertical direction perpendicular to the conveying direction. The pressing part is located at one end of the pressing body.

[0018] The pressing body oscillates around an axis so that the pressing part moves toward the conveying part located at the inlet end.

[0019] Using the above technical solution, the pressing body can swing around its axis, allowing the pressing part to move towards the conveyor section at the inlet end and apply pressing force to the handle pieces. The swinging motion is relatively gentle, helping to avoid impact damage to the handle pieces. The pressing part is located at one end of the pressing body, and the swinging motion of the pressing body drives the pressing part to move, thereby pressing the handle pieces entering the conveyor channel sequentially. In addition, the swinging pressing structure can adapt to handle pieces of different thicknesses. When the thickness of the handle piece changes, the swing angle of the pressing body can be adjusted accordingly, which helps to improve the adaptability of the device. Furthermore, the swinging structure has fewer moving parts and a simpler mechanical structure, which helps to reduce the failure rate and maintenance costs.

[0020] The present invention also discloses a handle piece transfer device for bag making equipment. The handle piece transfer device further includes a conveying drive component, which is connected to the conveyor belt assembly and the pressing component for transmission.

[0021] The conveyor drive unit can drive the pressing component to press the handle piece that enters the conveyor channel from the inlet end, and drive the conveyor belt of the conveyor belt assembly to convey the handle piece.

[0022] Using the above technical solution, the conveyor drive unit simultaneously powers both the pressing component and the conveyor belt assembly, achieving synchronous linkage between the pressing operation and the handle sheet conveying operation. Compared to independent drive structures, the integrated linkage transmission structure can coordinate the operating rhythm of the two sets of working mechanisms, reducing problems such as misalignment and conveying jams caused by misaligned action sequences, and helping to improve the continuity and smoothness of handle sheet transfer. In addition, the shared drive structure can simplify the parts of the bag-making equipment, making it easier to reduce the energy consumption and maintenance costs of the bag-making equipment, and helping to improve overall operating efficiency.

[0023] The present invention also discloses a handle piece transfer device for bag making equipment. The conveying drive component includes a conveying drive motor, and the output end of the conveying drive motor is provided with a first transmission belt group that is connected to the end of the pressing body away from the pressing part. The output end of the conveying drive motor is also provided with a second transmission belt group that is connected to an intermediate transmission belt group. One of the conveying support rollers of the conveying belt group is connected to the intermediate transmission belt of the intermediate transmission belt group.

[0024] Furthermore, the pressing part includes a pressing roller disposed at one end of the pressing body. The axis of the pressing roller is parallel to the vertical direction and can rotate relative to the pressing body about the vertical direction.

[0025] Using the above technical solution, the conveyor drive motor transmits power to the pressing body via the first transmission belt group, driving the pressing body to swing and achieve the pressing action; the power is then transmitted to the intermediate transmission belt group via the second transmission belt group, and then to the conveyor support roller via the intermediate transmission belt, driving the conveyor belt to rotate and achieve the conveying of the handle piece. The first transmission belt group and the second transmission belt group are connected from the output end of the same motor, so that the pressing action and the conveying action are driven by the same power source and kept synchronized.

[0026] The pressing part uses a pressing roller with its axis parallel to the vertical direction. This allows the pressing roller to contact the handle plate in a rolling manner during pressing. Compared to sliding contact, rolling contact reduces frictional damage to the handle plate surface, helping to protect its surface quality. The pressing roller can rotate relative to the pressing body, allowing it to rotate with the movement of the handle plate during pressing, reducing pressing resistance and improving the smoothness of pressing.

[0027] The present invention also discloses a handle piece transfer device for bag making equipment. An adjusting wheel group is provided between the conveyor drive motor and the intermediate transmission belt group, and on the side of the second transmission belt group. The transmission belt of the second transmission belt group can be sleeved on the adjusting wheel group and connected to the intermediate transmission belt group for transmission.

[0028] By adopting the above technical solution, an adjusting wheel set is set on the side of the second transmission belt set. The power of the second transmission belt set can be transmitted to the intermediate transmission belt set through the adjusting wheel set, thereby adjusting the conveying speed to match the conveying requirements of different specifications of handle pieces.

[0029] The present invention also discloses a handle piece transfer device for bag making equipment, wherein an adjustment component is provided on one side of the conveyor belt assembly near the outlet end.

[0030] The adjustable component has multiple adjustable sections that sequentially adjust the spacing between two adjacent handle pieces on one side of the conveyor belt.

[0031] Using the above technical solution, the spacing adjustment component sequentially adjusts the spacing between adjacent handle pieces on the conveyor belt through multiple adjustment sections. This ensures that the handle pieces have a suitable spacing when they reach the exit end, facilitating accurate alignment with the handle fixing parts of the sheet material being transported on the bag-making equipment. If the spacing between adjacent handle pieces is too large or too small, the handle pieces may not correspond to the handle fixing parts on the sheet material. The spacing adjustment component helps ensure the accuracy of the alignment between the handle pieces and the sheet material, reducing defects caused by improper spacing. Furthermore, the sequential adjustment of multiple adjustment sections allows for gradual spacing adjustment.

[0032] In addition, the spacing adjustment component is located near the outlet end, so that the spacing adjustment is completed just before the handle plate is output, which helps to reduce secondary deviations in spacing during the conveying process.

[0033] The present invention also discloses a handle piece transfer device for bag making equipment. The adjusting component includes an adjusting chain set on the frame. The adjusting chain is located on the side of one side of the belt and extends parallel to the conveying direction. Multiple adjusting hooks are spaced apart on the adjusting chain to form multiple adjusting parts. The adjusting chain is connected to one of the drive rollers of the second drive belt group.

[0034] Using the above technical solution, the adjustable chain extends parallel to the conveying direction and is consistent with the movement direction of the conveyor belt. As the adjustable hooks move with the chain, they can push or limit the handle pieces on the belt, thus adjusting the spacing. The adjustable chain is connected to the drive rollers of the second drive belt group, meaning the adjustable chain is also driven by the conveying drive component, eliminating the need for an additional drive component, which simplifies the structure and reduces costs. Furthermore, the spacing of the adjustable hooks matches the conveying rhythm of the handle pieces, enabling individual spacing control of each handle piece.

[0035] The present invention also discloses a handle piece transfer device for bag making equipment, the handle piece transfer device further comprising a strip cutting assembly located on one side of the inlet end of the conveying component.

[0036] The strip cutting assembly includes a cutting component and strip feeding components and handle piece discharge components located on opposite sides of the cutting component. The discharge end of the handle piece discharge component corresponds to the inlet end of the conveying component.

[0037] The strip is fed by the strip feeding component toward the cutting component, and the strip cut by the cutting component forms a handle piece. The handle piece discharge component discharges the cut handle piece toward the inlet end of the conveying component.

[0038] By adopting the above technical solution, the strip is cut into handle pieces by the strip cutting component and then discharged to the inlet end of the conveying component. There is no need to prepare handle pieces separately and add a manual feeding process, which helps to improve the automation level and production efficiency of the handle piece transfer device.

[0039] Furthermore, the cutting component is located between the strip feeding component and the handle plate discharge component, which allows the strip feeding direction and the handle plate discharge direction to be consistent or arranged in a straight line, which helps to shorten the material flow path.

[0040] The present invention also discloses a handle piece transfer device for bag making equipment. The cutting component includes a cutting drive and a cutting roller. One end of the cutting roller is fitted with a cutter seat. The cutting drive and the other end of the cutting roller are connected by a cutting transmission gear set.

[0041] The strip feeding component includes a feeding drive and a pair of feeding roller groups spaced apart. Each feeding roller group includes multiple feeding rollers spaced apart, and a feeding roller for feeding the strip is sleeved at one end of each feeding roller. The feeding drive is connected to the feeding transmission gear set sleeved at the other end of each feeding roller.

[0042] The handle plate discharge component includes a discharge drive and a pair of discharge roller groups spaced apart. Each discharge roller group includes multiple discharge rollers spaced apart, and a discharge belt is sleeved on one end of each discharge roller. The discharge drive is connected to the discharge transmission gear group sleeved on the other end of each discharge roller.

[0043] Using the above technical solution, the cutting component drives the cutting transmission gear set through the cutting drive component, which in turn drives the cutting roller to rotate. The cutter holder rotates with the cutting roller to cut the strip. The strip feeding component drives the feeding transmission gear set through the feeding drive component, which in turn drives each feeding roller set to rotate. The feeding rollers clamp the strip for feeding. The multiple feeding rollers are spaced apart to help evenly distribute the clamping force and reduce the deformation of the strip during feeding. The handle piece discharge component drives the discharge transmission gear set through the discharge drive component, which in turn drives the discharge roller set to rotate. The discharge belt discharges the cut handle piece. The belt discharge method is relatively gentle and helps to avoid damage to the handle piece during discharge.

[0044] In addition, each component is equipped with an independent drive unit, allowing for independent adjustment of the cutting, feeding, and discharging speeds, which helps to adapt to the processing needs of handle pieces of different specifications. At the same time, the gear transmission system has a compact structure and stable transmission ratio, which helps to maintain the synchronous operation of each roller group.

[0045] The present invention also discloses a handle piece transfer device for a bag making equipment, which further includes a mounting base movably mounted on the frame of the bag making equipment, the mounting base including a pair of spaced-apart mounting sidewalls.

[0046] Among them, a pair of feeding roller sets, a cutting roller set and a pair of discharge roller sets are all set on a pair of mounting side walls. The feeding roller, the cutter holder and the discharge belt are located on one side of the pair of mounting side walls of the mounting base, and the feeding transmission gear set, the cutting transmission gear set and the discharge transmission gear set are located on the other side of the pair of mounting side walls of the mounting base.

[0047] Using the above technical solution, the mounting base integrates the feed roller assembly, cutting roller assembly, and discharge roller assembly onto a pair of mounting side walls, facilitating overall installation and disassembly. The feed rollers, cutter holder, and discharge belt are located on one side (working side), while each transmission gear assembly is located on the other side (transmission side). This separate layout of the working side and transmission side helps reduce interference from transmission components to the working area and facilitates separate operation during daily maintenance and repair.

[0048] The present invention also discloses a bag-making device, including any of the above-mentioned handle piece transfer devices for bag-making devices.

[0049] When the handle piece transfer device includes a strip cutting assembly and a mounting base, an adjusting guide rail is provided on the frame of the bag making equipment for assembling the mounting base, so as to adjust the position of the mounting base and the strip cutting assembly relative to the frame.

[0050] By adopting the above technical solution, the bag-making equipment achieves stable and rapid conveying of handle pieces through this handle piece transfer device, which helps improve the overall processing efficiency of the bag-making equipment. Furthermore, the mounting base is assembled onto the frame via adjustable guide rails, allowing the strip cutting assembly to move and adjust its position along the guide rails, facilitating adaptation to the handle fixing positions of bags of different sizes. When changing product specifications, alignment adjustments can be made simply by adjusting the position of the strip cutting assembly along the guide rails, thus improving the equipment's versatility and changeover efficiency.

[0051] The present invention also discloses a bag-making device, which further includes a pressing component located beside the outlet end of the conveying component, and the pressing component is connected to the conveying drive component of the conveying component.

[0052] The handle piece output from the outlet end of the conveying component is located at the handle fixing part of the sheet material being transported on the bag making equipment, and the pressing component presses the handle piece on the sheet material.

[0053] Using the above technical solution, the pressing component is located on the side of the outlet end. When the handle piece is output from the outlet end and reaches the handle fixing part of the sheet material, the pressing component presses the handle piece onto the sheet material, completing the bonding and positioning of the handle piece and the sheet material.

[0054] Furthermore, the clamping component is connected to the conveying drive component, which makes the clamping action synchronized and coordinated with the conveying action. This helps to ensure that the handle plate is clamped in time when it reaches the handle fixing position, reducing positional deviations caused by timing misalignment.

[0055] The beneficial effects of this utility model are as follows:

[0056] This utility model discloses a handle piece transfer device for bag making equipment, including a conveying component and a pressing component. The conveying component includes a conveying channel and a conveying part with engagement force. The handle piece enters from the inlet end and engages with the conveying part, and is conveyed along the conveying direction to the outlet end for output to the handle fixing part. The engagement force of the conveying part ensures that the handle piece maintains reliable contact with the conveying part during the conveying process. Compared with the existing structure that relies solely on surface friction, this reduces the offset and slippage of the handle piece during the conveying process. Furthermore, the pressing component is located beside the inlet end. By pressing the handle piece entering the conveying channel, the handle piece is fully engaged with the conveying part, which helps to prevent the handle piece from shifting or falling off due to poor engagement when entering the conveying channel. In addition, the handle piece can enter the conveying channel at a high speed and quickly engage with the conveying part, which helps to adapt to the high-speed automated bag making production rate.

[0079] As mentioned in the background section, the existing handle conveying structure relies solely on the friction between surfaces to complete the conveying process, which easily leads to handle offset, slippage, warping, or even detachment, greatly reducing the stability of handle transfer and also affecting the handle transfer rate.

[0080] Therefore, this utility model provides a handle piece transfer device for bag making equipment, including a conveying component and a pressing component. The conveying component has a conveying channel and a conveying section, and the conveying section has an engaging force for engaging with the handle piece. The handle piece enters from the inlet end and is conveyed by the conveying section to the outlet end for output. The pressing component is located beside the inlet end and presses the handle piece entering the conveying channel through a movable pressing part, so that the handle piece is fully engaged with the conveying section. Through the cooperation of the pressing action of the pressing component and the engaging force of the conveying section, from the pressing engagement at the inlet end to the continuous engagement during the conveying process, the stability of the handle piece during the conveying process is doubly guaranteed, reducing the risk of the handle piece shifting, slipping, curling, and falling off during the conveying process.

[0081] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0082] like Figure 1 As shown, the handle piece is usually a sheet material with a handle strip glued on it. By fixing the handle piece to the substrate that forms the bag body, the handle of the packaging bag is formed after the packaging bag is formed.

[0083] like Figure 2 As shown, this embodiment discloses a handle piece transfer device 10 for a bag-making equipment. This handle piece transfer device 10 includes a conveying component 100 and a pressing component 200. The conveying component 100 has a conveying channel and a conveying section 101 extending along the conveying direction Y. The handle piece enters the conveying channel from the inlet end of the conveying component 100 and is conveyed by the conveying section 101, and is output from the outlet end of the conveying component 100. The outlet end faces the handle fixing portion of the sheet material being transported on the bag-making equipment. The conveying section 101 has an engaging force that engages with the handle piece.

[0084] The pressing member 200 is located beside the inlet end of the conveying member 100. The pressing member 200 has a movable pressing part 201. The pressing part 201 can press the handle piece that enters the conveying channel from the inlet end in sequence, so that the handle piece engages with the conveying member 101.

[0085] In this embodiment, the handle piece enters from the inlet end and engages with the conveying section 101. It is then conveyed along the conveying direction Y to the outlet end and output to the handle fixing part. The engagement force of the conveying section 101 ensures that the handle piece maintains reliable contact with the conveying section 101 during the conveying process. Compared with the existing structure that relies solely on surface friction, this reduces the offset and slippage of the handle piece during the conveying process. Furthermore, the pressing member 200 is located beside the inlet end. By pressing the handle piece entering the conveying channel, the pressing member 201 ensures that the handle piece is fully engaged with the conveying section 101, which helps to prevent the handle piece from shifting or falling off due to poor engagement when entering the conveying channel.

[0086] Therefore, the conveying component 100 and the pressing component 200 of this handle piece transfer device 10 work together to improve the stability and continuity of handle piece transfer from the pressing engagement at the inlet end to the continuous engagement during the conveying process. In addition, the setting of the pressing component 200 enables the handle piece to enter the conveying channel at a high speed and quickly engage with the conveying unit 101, which helps to adapt to the high-speed automated bag making production rate.

[0087] This embodiment does not limit the specific structure and arrangement of the conveying component 100. For example, the conveying component 100 can adopt a belt conveying structure, with the conveying section 101 being an annular conveying belt extending along the conveying direction Y. The conveying belt is wound between multiple rollers, and the belt is driven to circulate by rotating the driving rollers. The handle is placed on the upper surface of the belt for conveying. The conveying component 100 can also adopt a roller conveying structure, with the conveying section 101 consisting of multiple rollers arranged at intervals along the conveying direction Y. A gap is left between adjacent rollers for the handle to pass through, and the handle is driven to move forward by rotating the driving rollers. The conveying component 100 can also adopt a chain conveying structure, with the conveying section 101 being a chain extending along the conveying direction Y. Support plates are arranged at intervals on the chain, and the handle is placed on the support plates and conveyed as it moves with the chain.

[0088] It should be noted that the method of achieving the bonding force on the conveying part 101 is not limited in this embodiment. For example, the bonding force can be provided by a high friction coefficient material on the surface of the conveying part 101, such as setting a rubber layer or a patterned structure on the conveying surface to increase the friction force; the bonding force can also be provided by negative pressure adsorption, by setting adsorption holes in the conveying part 101 and connecting a vacuum source to form adsorption force; the bonding force can also be provided by mechanical clamping, by setting flexible clamping members on both sides of the conveying part 101 to lightly clamp the handle piece.

[0089] Furthermore, this embodiment does not limit the specific structure and arrangement of the pressing component 200. For example, the pressing component 200 can adopt a lever-type pressing structure, with the pressing part 201 being a pressing element at one end of the lever. The pressing element presses the handle piece downward by rotating the lever around the fulcrum. The pressing component 200 can also adopt a cylinder-type pressing structure, with the pressing part 201 being a pressure plate at the end of the cylinder piston rod. The pressure plate moves up and down by extending and retracting the cylinder to press the handle piece. The pressing component 200 can also adopt a cam-type pressing structure, with the pressing part 201 being a pressure head at the end of the driven rod driven by the cam. When the cam rotates, the pressure head is driven by the driven rod to periodically press the handle piece.

[0090] The specific structure of the conveying component 100 will be described in detail below.

[0091] In this embodiment, as Figure 3 and Figure 4 As shown, the conveying component 100 includes a conveyor belt assembly 110 mounted on the frame 20 of the bag making equipment. One side of the conveyor belt assembly 110 is located beside the conveying channel and extends along the conveying direction Y to form a conveying section 101. The conveyor belt assembly 110 provides a continuously operating conveying surface, and the one side of the belt extends along the conveying direction Y to form the conveying section 101, providing a continuous conveying path for the handle piece.

[0092] Furthermore, a vacuum chamber is provided on the side of the conveying channel, and the conveying part 101 has an adsorption part 102 that communicates with the vacuum chamber. The conveying part 101 engages with the handle piece located in the conveying channel by the adsorption force of the adsorption part 102. The adsorption part 102 may be an adsorption hole opened on the conveying part 101 or a suction cup provided on the conveying part 101.

[0093] It should be noted that the vacuum chamber creates a negative pressure environment, which is applied to the handle pieces within the conveying channel by the adsorption unit 102. This allows the conveying unit 101 to engage with the handle pieces through adsorption. The adsorption force provides a more reliable engagement, further reducing the risk of the handle pieces shifting, slipping, or warping during conveying. Furthermore, the structural configuration of the adsorption unit 102 and the vacuum chamber can accommodate handle pieces of different specifications and materials. By adjusting the negative pressure, the adsorption force can be matched to the weight and area of ​​the handle pieces, thus expanding the applicability of the handle piece transfer device 10.

[0094] In addition, the adsorption force acts in a gentle manner, making it less likely to cause indentations or damage to the surface of the handle, thus helping to maintain the surface quality of the handle.

[0095] Specifically, the vacuum chamber can adopt a box-type sealed cavity structure, with an opening on one side of the box that connects to the adsorption section 102. A vacuum pump is connected to the cavity to create negative pressure. Alternatively, the vacuum chamber can adopt a tubular cavity structure, with multiple through holes on the side wall of the tubular cavity extending along the conveying direction Y that connect to the adsorption section 102, and connected to a vacuum source through pipelines.

[0096] Specifically, multiple adsorption units 102 are spaced apart on the conveyor belt, and a vacuum chamber is installed on one side of the belt away from the conveying channel. The multiple adsorption units 102 on the belt create adsorption force when passing through the area covered by the vacuum chamber, ensuring that the handle pieces are continuously adsorbed throughout the conveying process, thus helping to maintain the stability of the conveying process. The vacuum chamber being installed on the side of the belt away from the conveying channel ensures that the negative pressure area corresponds to the position of the adsorption units 102, resulting in a compact structural layout that helps reduce the overall size of the device. Furthermore, the belt conveyor system operates smoothly and with low noise, making it suitable for continuous high-speed operation and facilitating adaptation to high-speed automated bag-making production rates.

[0097] It should be noted that the vacuum chamber can be set close to the back of the belt, and a sealing strip is set between the opening of the chamber and the back of the belt to reduce air leakage; the vacuum chamber can also maintain an appropriate gap with the back of the belt, and be connected to the adsorption part 102 through a transition channel, with a flexible seal set at the gap that moves with the belt.

[0098] The structure of the pressing component 200 will be described in detail below.

[0099] like Figure 3 and Figure 4 As shown, in this embodiment, the pressing component 200 includes a pressing body 210 mounted on the frame 20 of the bag-making equipment and capable of swinging about an axis extending in a vertical direction X perpendicular to the conveying direction Y. The pressing body 210 can be configured as a rod-shaped or plate-shaped structure, and the pressing part 201 is located at one end of the pressing body 210. It should be noted that the middle part of the pressing body 210 can be mounted on the frame 20 via a hinge to form a swing fulcrum.

[0100] In this embodiment, the pressing body 210 can swing around its axis, allowing the pressing part 201 to move towards the conveying part 101 at the inlet end and apply pressing force to the handle pieces. The swinging motion is relatively gentle, helping to avoid impact damage to the handle pieces. The pressing part 201 is located at one end of the pressing body 210. The swinging motion of the pressing body 210 drives the pressing part 201 to move, thereby pressing the handle pieces entering the conveying channel sequentially. In addition, the swinging pressing structure can adapt to handle pieces of different thicknesses. When the thickness of the handle piece changes, the swing angle of the pressing body 210 can be adjusted accordingly, which helps to improve the adaptability of the device. Furthermore, the swinging structure has fewer moving parts and a simpler mechanical structure, which helps to reduce the failure rate and maintenance costs.

[0101] Specifically, the pressing part 201 includes a pressing roller 202 disposed at one end of the pressing body 210. The axis of the pressing roller 202 is parallel to the vertical direction X and can rotate relative to the pressing body 210 about the vertical direction X. When pressing, the pressing roller 202 contacts the handle piece in a rolling manner. Compared with sliding contact, rolling contact can reduce frictional damage to the surface of the handle piece, which helps to protect the surface quality of the handle piece. Furthermore, the pressing roller 202 can rotate relative to the pressing body 210, so that the roller can rotate with the movement of the handle piece during the pressing process, reducing pressing resistance and helping to improve the smoothness of pressing.

[0102] More specifically, the pressing roller 202 can be a rubber-coated roller, with an outer layer of rubber material and an inner layer of metal bearing core. The relatively soft rubber surface helps to reduce indentations on the handle plate. The pressing roller 202 can also be a polyurethane roller, made entirely of polyurethane material, which has good wear resistance and a moderate surface friction coefficient. The pressing roller 202 can also be a metal roller with an elastic material covering its surface. The metal core provides structural rigidity, and the surface elastic layer provides cushioning. This embodiment does not limit this to a single method.

[0103] The drive structure of the conveying component 100 and the pressing component 200 will be described in detail below.

[0104] like Figure 3 and Figure 4 As shown, in this embodiment, the handle piece transfer device 10 further includes a conveying drive 300, which is connected to the conveyor belt assembly 110 and the pressing component 200 in a transmission connection.

[0105] The conveying drive unit 300 can drive the pressing unit 200 to press the handle piece that enters the conveying channel from the inlet end, and drive the conveyor belt of the conveyor belt group 110 to convey the handle piece.

[0106] In other words, the conveyor drive unit 300 simultaneously powers both the pressing component 200 and the conveyor belt assembly 110, enabling synchronized operation of the pressing and handle sheet conveying processes. Compared to independent drive structures, the integrated linkage transmission structure coordinates the operating rhythms of the two working mechanisms, reducing issues such as misalignment and conveying jams caused by misaligned action sequences, thus improving the continuity and smoothness of handle sheet transfer. Furthermore, the shared drive structure simplifies the components of the bag-making equipment, reducing energy consumption and maintenance costs, and ultimately improving overall operational efficiency.

[0107] Specifically, the conveying drive unit 300 includes a conveying drive motor, and the output end of the conveying drive motor is provided with a first transmission belt group 310 which is connected to the end of the pressing body 210 away from the pressing part 201. The output end of the conveying drive motor is also provided with a second transmission belt group 320 which is connected to an intermediate transmission belt group 330. One of the conveying support rollers of the conveying belt group 110 is connected to the intermediate transmission belt of the intermediate transmission belt group 330.

[0108] In this embodiment, the conveyor drive motor transmits power to the pressing body 210 via the first transmission belt group 310, driving the pressing body 210 to swing and achieve the pressing action; the second transmission belt group 320 transmits power to the intermediate transmission belt group 330, and then the intermediate transmission belt transmits power to the conveyor support roller, driving the conveyor belt to rotate and achieve the conveying of the handle piece. The first transmission belt group 310 and the second transmission belt group 320 are connected from the output end of the same motor, so that the pressing action and the conveying action are driven by the same power source and kept synchronized.

[0109] Furthermore, such as Figure 4 As shown, an adjusting wheel assembly 400 is also provided between the conveyor drive motor and the intermediate transmission belt assembly 330, located beside the second transmission belt assembly 320. The transmission belt of the second transmission belt assembly 320 can be fitted onto the adjusting wheel assembly 400 and connected to the intermediate transmission belt assembly 330 for transmission. This allows the transmission speed to be adjusted via the adjusting wheel assembly 400 to the intermediate transmission belt assembly 330, thereby adjusting the conveying speed to match the conveying requirements of different sized handle pieces. It should be noted that the adjusting wheel assembly 400 may include multiple cooperating adjusting gears. These gears change the transmission ratio between the second transmission belt assembly 320 and the intermediate transmission belt assembly 330. These multiple adjusting gears can be mounted on a dedicated mounting plate.

[0110] When multiple handle plates are arranged sequentially on the conveyor belt and conveyed forward, the spacing between adjacent handle plates may be uneven due to fluctuations in upstream material supply. Therefore, as follows: Figure 3 and Figure 4 As shown, in this embodiment, a pitch adjustment component 500 is provided on one side of the conveyor belt assembly 110 near the outlet end.

[0111] The adjusting component 500 has multiple adjusting sections 501 that sequentially adjust the spacing between two adjacent handle pieces conveyed on one side of the belt. This ensures that the handle pieces have a suitable spacing when they reach the exit end, facilitating accurate alignment with the handle fixing parts of the sheet material being transported on the bag-making equipment. If the spacing between adjacent handle pieces is too large or too small, the handle pieces may not correspond to the handle fixing parts on the sheet material. The adjusting component 500 helps ensure the accurate alignment of the handle pieces and the sheet material, reducing defects caused by improper spacing. Furthermore, the sequential adjustment of the multiple adjusting sections 501 allows for gradual spacing adjustment.

[0112] In addition, the spacing adjustment component 500 is located near the outlet end, so that the spacing adjustment is completed just before the handle plate is output, which helps to reduce secondary deviations in spacing during the conveying process.

[0113] Specifically, the pitch adjustment component 500 includes a pitch adjustment chain 510 disposed on the frame 20. Part of the pitch adjustment chain 510 is located on the side of one side of the belt and extends parallel to the conveying direction Y. Multiple pitch adjustment hooks 502 are spaced apart on the pitch adjustment chain 510 to form multiple pitch adjustment parts 501. The pitch adjustment chain 510 is connected to one of the drive rollers of the second drive belt group 320.

[0114] In this embodiment, the adjustable chain 510 extends parallel to the conveying direction Y and is consistent with the movement direction of the conveyor belt. As the adjustable hook 502 moves with the adjustable chain 510, it can push or limit the handle pieces on the belt, thereby adjusting the spacing. The adjustable chain 510 is connected to the drive roller of the second drive belt group 320, so that the adjustable chain 510 is also driven by the conveying drive component 300, eliminating the need for an additional drive component, which helps simplify the structure and reduce costs. Furthermore, the spacing of the adjustable hooks 502 matches the conveying rhythm of the handle pieces, enabling individual spacing control of each handle piece.

[0115] Specifically, when the movement speed of the adjusting chain 510 is faster than that of the conveyor 101, the adjusting hook 502 can push the handle piece on the belt body as it moves with the adjusting chain 510. When the movement speed of the adjusting chain 510 is slower than that of the conveyor 101, the adjusting hook 502 can limit the handle piece on the belt body as it moves with the adjusting chain 510.

[0116] Of course, the adjusting component 500 can also adopt a block-type adjusting structure. Multiple adjusting parts 501 are blocks arranged at intervals along the conveying direction Y. The blocks can be raised and lowered. When raised, they block the handle plate, and when lowered, they allow passage. The spacing can be adjusted by controlling the raising and lowering sequence of each block. The adjusting component 500 can also adopt a cam-type adjusting structure. Multiple adjusting parts 501 are cam push rods arranged at intervals along the conveying direction Y. When the cam rotates, the push rods periodically extend to push the handle plate to adjust the spacing.

[0117] Furthermore, such as Figures 5 to 7 As shown, in this embodiment, the handle piece transfer device 10 also includes a strip cutting assembly 600 located on one side of the inlet end of the conveying component 100. It should be noted that the strip is actually a long strip structure of multiple handle strips pasted at intervals, which can only be formed into a handle piece after being cut.

[0118] The strip cutting assembly 600 includes a cutting component 610 and a strip feeding component 620 and a handle piece discharge component 630 located on opposite sides of the cutting component 610. The discharge end of the handle piece discharge component 630 corresponds to the inlet end of the conveying component 100.

[0119] The strip is fed by the strip feeding component 620 toward the cutting component 610, and the cutting component 610 cuts the strip to form a handle piece. The handle piece discharge component 630 discharges the cut handle piece to the inlet end of the conveying component 100. There is no need to prepare the handle piece separately and add a manual feeding process, which helps to improve the automation level and production efficiency of the handle piece transfer device 10.

[0120] Furthermore, the cutting component 610 is located between the strip feeding component 620 and the handle piece discharge component 630, so that the feeding direction of the strip and the discharge direction of the handle piece can be consistent or arranged in a straight line, which helps to shorten the material flow path. In this embodiment, the feeding direction of the strip and the discharge direction of the handle piece are arranged in a straight line and are both perpendicular to the conveying direction Y of the conveying component 100. After the handle piece is discharged from the discharge component, it is conveyed in a different direction by the conveying component 100.

[0121] Specifically, such as Figure 6 As shown, the cutting component 610 includes a cutting drive component 611 and a cutting roller 612. One end of the cutting roller 612 is fitted with a cutter holder 613. The other end of the cutting drive component 611 and the cutting roller 612 are connected by a cutting transmission gear set 614.

[0122] The strip feeding component 620 includes a feeding drive 621 and a pair of feeding roller groups 622 spaced apart. Each feeding roller group 622 includes a plurality of feeding rollers spaced apart, such as two, three, four, five or other numbers of feeding rollers spaced apart. Each feeding roller has a feeding roller 623 for feeding strips sleeved at one end. The feeding drive 621 is connected to the feeding transmission gear group 624 sleeved at the other end of each feeding roller.

[0123] The handle plate discharge component 630 includes a discharge drive component 631 and a pair of discharge roller groups 632 arranged at intervals. Each discharge roller group 632 includes multiple discharge rollers arranged at intervals. Each discharge roller group 632 includes two, three, four, six or other numbers of discharge rollers arranged at intervals. One end of the multiple discharge rollers is fitted with a discharge belt 633. The discharge drive component 631 is connected to the discharge transmission gear group 634 fitted at the other end of each discharge roller.

[0124] In this embodiment, the cutting component 610 drives the cutting transmission gear set 614 through the cutting drive component 611, which drives the cutting roller 612 to rotate synchronously. The cutter holder 613 rotates with the cutting roller 612 to cut the strip. Of course, a cutter holder can be provided on the opposite side of the cutting roller 612, or a pair of cutting rollers 612 can be provided to rotate towards each other to achieve cutting. The strip feeding component 620 drives the feeding transmission gear set 624 through the feeding drive component 621, which drives each feeding roller set 622 to rotate. The feeding roller 623 clamps the strip for feeding. The multiple feeding rollers are spaced apart to help evenly distribute the clamping force and reduce the deformation of the strip during feeding. The handle piece discharge component 630 drives the discharge transmission gear set 634 through the discharge drive component 631, which drives the discharge roller set 632 to rotate. The discharge belt 633 discharges the cut handle piece. The belt discharge method is relatively gentle, which helps to avoid damage to the handle piece during the discharge process.

[0125] In addition, each component is equipped with an independent drive unit, allowing for independent adjustment of the cutting, feeding, and discharging speeds, which helps to adapt to the processing needs of handle pieces of different specifications. At the same time, the gear transmission system has a compact structure and stable transmission ratio, which helps to maintain the synchronous operation of each roller group.

[0126] Of course, each component may also adopt a common drive structure similar to that of the conveying component 100 and the pressing component 200; this embodiment does not limit this to a single one.

[0127] It should be noted that, as Figure 5 As shown, this handle transfer device 10 also includes a mounting base 700 movably mounted on the frame 20 of the bag making equipment, the mounting base 700 including a pair of spaced-apart mounting sidewalls 710.

[0128] Among them, such as Figure 6 As shown, a pair of feed roller sets 622, a cutting roller set 612, and a pair of discharge roller sets 632 are all mounted on a pair of mounting sidewalls 710. The feed roller 623, the cutter holder 613, and the discharge belt 633 are located on one side of the pair of mounting sidewalls 710 of the mounting base 700. Figure 7 As shown, the feeding transmission gear set 624, the cutting transmission gear set 614, and the discharge transmission gear set 634 are located on the other side of a pair of mounting sidewalls 710 of the mounting base 700.

[0129] In this embodiment, the mounting base 700 integrates the feed roller assembly 622, the cutting roller 612, and the discharge roller assembly 632 onto a pair of mounting sidewalls 710, facilitating overall installation and disassembly. The feed roller 623, the cutter holder 613, and the discharge belt 633 are located on one side (working side), while each transmission gear assembly is located on the other side (transmission side). This separate layout of the working side and the transmission side helps reduce interference from the transmission components to the working area and facilitates separate operation during routine maintenance and repair, especially for replacing the discharge belt 633.

[0130] This embodiment also discloses a bag-making device, including the handle piece transfer device 10 for bag-making devices described above.

[0131] When the handle piece transfer device 10 includes a strip cutting assembly 600 and a mounting base 700, an adjustment guide rail is provided on the frame 20 of the bag making equipment for assembling the mounting base 700, so as to adjust the position of the mounting base 700 and the strip cutting assembly 600 relative to the frame 20.

[0132] In this embodiment, the bag-making equipment achieves stable and rapid conveying of the handle pieces through the handle piece transfer device 10, which helps improve the overall processing efficiency of the bag-making equipment. Furthermore, the mounting base 700 is mounted on the frame 20 via adjustable guide rails, allowing the strip cutting assembly 600 to move and adjust its position along the guide rails, facilitating adaptation to the position of the handle fixing parts of bags of different specifications. When changing product specifications, the alignment adjustment can be completed by adjusting the position of the strip cutting assembly 600 via the guide rails, which helps improve the versatility of the equipment and changeover efficiency.

[0133] Furthermore, such as Figure 2 and Figure 3 As shown, the bag making equipment also includes a pressing component 30 located beside the outlet end of the conveying component 100, and the pressing component 30 is connected to the conveying drive component 300 of the conveying component 100.

[0134] The handle piece output from the outlet end of the conveying component 100 is located at the handle fixing part of the sheet material being transported on the bag making equipment, and the pressing component 30 presses the handle piece on the sheet material.

[0135] In this embodiment, the pressing component 30 is located beside the outlet end. When the handle piece is output from the outlet end and reaches the handle fixing part of the sheet material, the pressing component 30 presses the handle piece onto the sheet material, completing the bonding and positioning of the handle piece and the sheet material.

[0136] Furthermore, the clamping component 30 is connected to the conveying drive component 300, which makes the clamping action and the conveying action synchronized and coordinated. This helps to ensure that the handle piece is clamped in time when it reaches the handle fixing position, reducing positional deviation caused by timing misalignment.

[0137] This embodiment does not limit the specific structure and setting of the pressing component 30. For example, the pressing component 30 can adopt a spring pressure roller structure. The pressing roller 32 is installed on the frame 20 through the pressing body 31. A spring is set on the pressing body 31 to apply downward pressure to the pressure roller. The pressing body 31 can cooperate with a cam on one of the support rollers of the intermediate transmission belt group 330. When the handle plate passes by, the cam squeezes the pressing body 31, so that the pressing body 31 overcomes the spring force and swings. The pressing roller 32 presses the handle plate with elastic force.

[0138] The pressing component 30 can also adopt a cylinder pressing plate structure. The cylinder is installed on the frame 20, and the piston rod end is connected to the pressing plate. The cylinder extends and retracts to drive the pressing plate to move up and down to press the handle piece. The pressing component 30 can also adopt a cam pressing rod structure. The cam is driven to rotate by the conveying drive component 300. The motion of the cam is converted into the up and down reciprocating motion of the pressing rod through the driven rod to press the handle piece.

[0139] The working process of the handle transfer device 10 will be described in detail below.

[0140] The belt is fed to the cutting unit 610 via the belt feeding unit 620. The cutting unit 610 cuts the belt into individual handle pieces of a set length. The handle piece discharge unit 630 discharges the cut handle pieces to the inlet end of the conveying unit 100. When the handle pieces enter the conveying channel, the pressing part 201 of the pressing unit 200 applies pressing force to the handle pieces under the drive of the conveying drive motor, so that the handle pieces are fully engaged with the conveying part 101 of the conveyor belt assembly 110. The adsorption part 102 on the conveying part 101 forms an adsorption force when passing through the vacuum chamber coverage area, so that the handle pieces are adsorbed and fixed to the surface of the belt. The conveying drive motor drives the conveyor belt to rotate through the second transmission belt assembly 320 and the intermediate transmission belt assembly 330, and the handle pieces move with the belt along the conveying direction Y. The adjusting hook 502 on the adjusting chain 510 moves synchronously beside the belt to adjust the spacing between adjacent handle pieces in sequence. When the handle piece reaches the outlet end, it is output to the handle fixing part of the sheet material being transported on the bag making equipment. The pressing component 30 then presses the handle piece onto the sheet material, completing the transfer and positioning of the handle piece.

[0141] Throughout the entire operation, the conveyor drive unit 300 simultaneously provides power to the pressing component 200, the conveyor belt assembly 110, and the adjustable chain 510, achieving synchronous linkage of the three sets of operations: pressing, conveying, and adjusting. The pressing action of the pressing component 200 and the suction force of the conveying unit 101 work together to ensure the stability of the handle piece during the conveying process, from the pressing engagement at the inlet end to the continuous suction during the conveying process.

[0142] In addition, the conveying drive 300 is also used to drive the pressing component 30, so that the handle piece is pre-pressed on the handle fixing part of the substrate.
