Conveying mechanism of paper bag machine

Abstract

The utility model discloses a conveying mechanism of a paper bag machine, which comprises a conveying component movably mounted on a frame. In the width direction of the conveying assembly, the limiting assembly is fixedly installed on the rack and located on the corresponding side of the conveying assembly, and the edge clamping assemblies are arranged on the corresponding side of the conveying assembly at intervals in the conveying direction of the conveying assembly and are in sliding connection with the limiting assembly. The side, close to the conveying assembly, of the limiting assembly is provided with a limiting rail. One end of each edge clamping assembly is provided with a rolling component capable of being matched in the limiting rail in a rolling mode. According to the conveying mechanism of the paper bag machine, in the bag blank conveying process, due to the fact that one end of the edge clamping assembly rolls in the limiting rail through the rolling component, the position of the edge clamping assembly is limited by the limiting assembly, and even if the conveying assembly shakes in the bag blank conveying process due to the fact that a power mechanism transmits power, the edge clamping assembly can not rotate. And the side clamp assembly does not collide with other mechanisms on the paper bag machine such as the rack to generate noise.

Description

Technical Field

[0001] The utility model belongs to the technical field of three-dimensional bag forming, in particular to a conveying mechanism of a paper bag machine. Background Art

[0002] Paper bag machine is an automated equipment used to produce environmentally friendly paper packaging bags, mainly used for the production of shopping bags, clothing bags, food bags and other products.

[0003] In the process of producing paper bags, the paper bag machine in the prior art needs to cut the sheet material into bag blanks one by one through a cutting device, and then convey the bag blanks to the crimping device on the paper bag machine through a conveying device for double crimping. The crimped bag blanks are then conveyed by the conveying device to the bottom opening device for bottom opening. The bag blanks with bottom opening are conveyed by the conveying device to the gluing device for gluing. The glued bag blanks are then conveyed to the bottom closing device for bottom closing, thereby making a complete paper bag. The finished paper bag is then conveyed to the packaging device for packaging.

[0004] Specifically, the conveying device needs to clamp both sides of the bag blank during the process of conveying the bag blank, so multiple clamping mechanisms are set on both sides of the conveying device. However, with the increasing demand for miniaturization of paper bag machines, the structure of paper bag machines is designed to be relatively compact, so that after the clamping mechanisms are installed on both sides of the conveying device, their positions are not limited. Therefore, during the operation of the conveying device, the conveying mechanism will vibrate slightly because the power mechanism needs to transmit power, thereby causing the clamping mechanism to vibrate, resulting in collisions between the clamping mechanism and structures on the paper bag machine such as the frame, causing the paper bag machine to make loud noises when producing paper bags. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that during the operation of the conveying device of the paper bag machine, when the power mechanism transmits power, the conveying mechanism will vibrate slightly, thereby linking the clamping mechanism to vibrate, causing the clamping mechanism to collide with the structure of the paper bag machine such as the frame, resulting in the paper bag machine making a loud noise when producing paper bags.

[0006] In order to solve the above problems, the utility model provides a conveying mechanism of a paper bag machine, comprising a conveying assembly movably mounted on a frame, a limiting assembly fixedly mounted on the frame and located on a corresponding side of the conveying assembly in the width direction of the conveying assembly, and at least one side clamp assembly spaced apart along the conveying direction of the conveying assembly on a corresponding side of the conveying assembly and slidably connected to the limiting assembly; wherein a limiting track is provided on a side of the limiting assembly close to the conveying assembly, and a rolling member is provided at one end of each side clamp assembly that is rollably adapted to fit within the limiting track.

[0007] Moreover, along the conveying direction of the bag blank, the limiting track is sequentially formed with a driving clamping section and a driving releasing section from the input end to the output end of the conveying component; wherein, when the bag blank is conveyed to the input end of the conveying component, the rolling member enters the driving clamping section, and the linked side clamping assembly clamps the corresponding side of the bag blank on the conveying component; and, when the bag blank is conveyed to the output end of the conveying component along the conveying direction, the rolling member enters the driving releasing section, and the linked side clamping assembly releases the corresponding side of the bag blank.

[0008] By adopting the above-mentioned technical solution, during the operation of this conveying mechanism, when the sheet material enters the input end of the conveying component, the rolling member enters the drive clamping section of the limiting track, thereby linking the side clamping assembly to clamp the corresponding side of the bag blank on the conveying component, so that during the processing of the bag blank, the position of the bag blank will not shift, thereby ensuring the reliability of the bag blank processing; then, the conveying component continues to convey the bag blank along the conveying direction, and during this process, the rolling member continues to move in the drive clamping section of the limiting track, so that the bag blank is continuously clamped on the conveying surface of the conveying component until the bag blank is processed. The rolling member enters the drive release section, thereby linking the side clamping assembly to release the processed bag blank, and then the processed bag blank is collected.

[0009] It can be seen that in the process of conveying the bag blanks of the conveying mechanism of this paper bag machine, one end of the side clamp assembly rolls in the limiting track of the limiting assembly through the setting of a rolling member, so that the position of the side clamp assembly is limited by the limiting assembly. Even if the conveying assembly shakes when the power mechanism transmits power during the process of conveying the bag blanks, the side clamp assembly will not collide with other mechanisms on the paper bag machine such as the frame to generate noise, thereby reducing the noise of the paper bag machine during operation, and further reducing the noise in the paper bag machine production workshop.

[0010] Furthermore, an embodiment of the present invention also discloses a conveying mechanism of a paper bag machine, wherein the conveying assembly includes a driving component mounted on a frame, a rotating roller shaft arranged along the width direction and rotatably connected to the frame, and a conveying hub fixedly sleeved on the rotating roller shaft; the limiting assembly is configured as a circular base that is coaxially arranged relative to the conveying hub in the width direction and located on a corresponding side of the conveying hub; wherein the limiting track is arranged along the circumference of the circular base on a side close to the conveying hub and opens toward one side of the conveying hub.

[0011] By adopting the above technical solution, when conveying the bag blanks, the driving component drives the rotating roller to rotate, thereby linking the conveying hub to rotate to convey the bag blanks; compared with the method of conveying the bag blanks by setting a conveyor belt in the prior art, the conveying hub in the present application occupies less installation space for the paper bag machine in the length direction of the paper bag machine.

[0012] Furthermore, an embodiment of the present invention also discloses a conveying mechanism for a paper bag machine, wherein the driving clamping section and the driving releasing section of the limiting track are arranged in sequence and continuously in the circumferential direction of the circular base.

[0013] Among them, when viewed in the width direction, one end of the drive clamping section is opposite to the input end of the conveying hub, and the other end is opposite to the output end of the conveying hub, and the two ends of the drive release section are respectively connected to the two ends of the drive clamping section; and the radial dimension of the drive clamping section is larger than the radial dimension of the drive release section.

[0014] With the above technical solution, since the radial dimension of the drive clamping section is larger than the radial dimension of the drive release section, when the sheet material enters the input end of the conveying assembly and the rolling member enters the drive clamping section of the limiting track, the side clamping assembly can be linked to move toward the outer peripheral surface close to the conveying hub, thereby clamping the corresponding side of the bag blank on the outer peripheral surface of the conveying hub. After the bag blank is processed, the rolling member enters the drive release section, thereby linking the side clamping assembly to move toward the outer peripheral surface away from the conveying hub to release the processed bag blank; in this process, the rolling member is limited by the drive clamping section and the drive release section, thereby reducing the risk of collision between the side clamping assembly and other structures on the paper bag machine (such as the frame), thereby making the paper bag machine less noisy when working.

[0015] In addition, by arranging a limiting track on the circular base, on the one hand, it is possible to drive the side clamp assembly so that the side clamp assembly clamps or releases the bag blank, and on the other hand, it is also possible to limit the side clamp assembly, so that the conveying mechanism makes less noise when working; therefore, this conveying mechanism has the advantages of simple structure and easy maintenance.

[0016] Furthermore, an embodiment of the present invention also discloses a conveying mechanism of a paper bag machine, wherein the side clamp assembly includes a mounting frame fixedly mounted on a corresponding side of a conveying hub in a width direction, and a clamping component and a transmission component mounted on the mounting frame, wherein one end of the transmission component is provided with a rolling member and the other end is transmission-connected to the clamping component; and when the bag blank is conveyed to the input end of the conveying hub, the rolling member enters the drive clamping section, and the transmission component links the end of the clamping component to clamp the corresponding side of the bag blank on the outer peripheral surface of the conveying hub.

[0017] Specifically, the mounting bracket includes a first connecting seat fixedly mounted on a corresponding side of the conveying hub in the width direction, and a second connecting seat fixedly mounted on a side of the first connecting seat close to the limiting assembly.

[0018] Among them, the clamping component is rotatably connected to the first connecting seat, can swing around the conveying direction, and the end portion can switch between a clamping position and a release position relative to the outer circumferential surface of the conveying hub. The transmission component is movably arranged on the second connecting seat, can move along the height direction of the mounting frame with the rolling component, and link the clamping component to swing around the conveying direction.

[0019] By adopting the above technical solution, when the sheet material enters the input end of the conveying assembly and the rolling member enters the driving clamping section of the limiting track, the transmission member can be linked to move in the direction close to the outer peripheral surface of the conveying hub, and drive the clamping member to swing relative to the first connecting seat in the direction close to the outer peripheral surface of the conveying hub and clamp the bag blank on the outer peripheral surface of the conveying hub; when the bag blank is processed, the rolling member enters the driving release section, the transmission member can be linked to move in the direction away from the outer peripheral surface of the conveying hub, and drive the clamping member to swing relative to the first connecting seat in the direction away from the outer peripheral surface of the conveying hub and release the bag blank; in this process, the clamping member clamps or releases the bag blank by swinging, so no relative friction will occur between the bag blanks, thereby avoiding the problem of the position of the bag blank being offset due to the relative friction between the two when the clamping member clamps or releases the bag blank.

[0020] Furthermore, an embodiment of the present invention also discloses a conveying mechanism of a paper bag machine, in which the rolling member is configured as a rolling wheel; a slide groove along the height direction is opened on one side of the second connecting seat, and the transmission component includes a slide rod extending along the height direction and slidingly connected to the slide groove, and a transmission rod having one end transmission connected to the corresponding side of the slide rod and the other end extending along the height direction and transmission connected to the clamping component.

[0021] Among them, transmission limit parts are correspondingly provided at both ends of the transmission rod, and the rolling wheel is rotatably connected to one end of the sliding rod close to the circular base and is rollingly connected to the limit track.

[0022] By adopting the above technical solution, the rolling component is set as a rolling wheel, thereby reducing the friction between the rolling component and the limiting track when sliding in the limiting track, further reducing the probability of the rolling component and the limiting track being stuck due to excessive friction, so that the clamping component can reliably clamp the bag blank.

[0023] Moreover, when the sheet material enters the input end of the conveying hub and the rolling wheel enters the driving clamping section of the limiting track, the sliding rod can be linked to move toward the outer peripheral surface of the conveying hub in the height direction and the transmission rod can be linked to move in the height direction, thereby driving the clamping component to rotate relative to the first connecting seat through the transmission rod to clamp the bag blank on the outer peripheral surface of the conveying hub. The clamping component can clamp the bag blank through a simple structural setting. Therefore, this structural setting can reduce the manufacturing cost of the conveying component and facilitate maintenance.

[0024] In addition, transmission limiters are correspondingly provided at both ends of the transmission rod, which can effectively transmit the power applied by the rolling wheel to the sliding rod to the clamping component via the transmission rod, providing an effective power source for the clamping component to clamp or release the bag blank.

[0025] Furthermore, an embodiment of the present invention also discloses a conveying mechanism of a paper bag machine, wherein the transmission limit members at both ends of the transmission rod are respectively configured as a first internally threaded joint bearing at one end of the transmission rod and a second internally threaded joint bearing at the other end.

[0026] Among them, a connecting rod is provided on the corresponding side of the sliding rod, one end of the connecting rod is fixedly connected to the corresponding side of the sliding rod, and the other end extends toward one end of the transmission rod and is fixedly connected to the inner ring of the first internally threaded joint bearing; one end of the transmission rod is fixedly connected to the outer ring of the first internally threaded joint bearing, and the other end is fixedly connected to the inner ring of the second internally threaded joint bearing; and the corresponding end of the clamping part is fixedly connected to the outer ring of the second internally threaded joint bearing.

[0027] By adopting the above technical solution, a first internally threaded spherical bearing and a second internally threaded spherical bearing are respectively arranged at both ends of the transmission rod. On the one hand, the connection strength between the connecting rod and one end of the transmission rod, and between the other end of the transmission rod and the clamping component is guaranteed; on the other hand, since the spherical sliding structure of the first internally threaded spherical bearing and the second internally threaded spherical bearing allows the inner ring to swing in any direction, the installation error existing during the installation between the connecting rod and one end of the transmission rod, and between the other end of the transmission rod and the clamping component can be compensated, thereby avoiding jamming between the connecting rod and one end of the transmission rod, and between the other end of the transmission rod and the clamping component, thereby ensuring the continuity of power transmission.

[0028] Furthermore, an embodiment of the present invention also discloses a conveying mechanism of a paper bag machine, wherein a limit plate is further provided on the second connecting seat, and the limit plate cover is provided in the slide groove and fixedly connected to the second connecting seat.

[0029] By adopting the above technical solution, the sliding rod is limited by setting a limit plate, so that the sliding rod will not fall out of the sliding groove during the movement in the sliding groove; when the conveying hub suddenly stops running, the sliding rod will not fall out of the sliding groove due to the action of inertia; and when the sliding rod is subjected to the centrifugal force of the rotation of the conveying hub, the risk of the sliding rod falling out of the sliding groove can also be reduced by the limit plate.

[0030] Furthermore, an embodiment of the present invention also discloses a conveying mechanism of a paper bag machine, wherein the clamping component includes a rotating seat rotatably connected to a first connecting seat, a clamping head having one end fixedly connected to the rotating seat and the other end extending in the height direction toward the conveying surface of the conveying hub, and a connecting rod having one end fixedly connected to the rotating seat and the other end extending in the width direction and fixedly connected to the outer ring of the second internally threaded joint bearing.

[0031] Furthermore, an embodiment of the present invention also discloses a conveying mechanism of a paper bag machine, wherein a limiting rod is provided on the rotating seat along the length direction of the mounting frame and passes through the rotating seat; and both ends of the limiting rod extend out of the rotating seat respectively and are opposite to the side of the first connecting seat close to the second connecting seat in the width direction.

[0032] By adopting the above technical solution, when the bag blank enters the output end of the conveying hub and the rolling wheel enters the driving release section of the limiting track, the linkage slide rod moves away from the outer circumference of the conveying hub in the height direction and the linkage transmission rod moves in the height direction, thereby driving the rotating seat to rotate away from the outer circumference of the conveying hub relative to the first connecting seat through the transmission rod, and causing the clamping head to swing in the direction away from the outer circumference of the conveying hub to release the processed bag blank; and by setting the limiting rod to limit the rotation angle of the rotating seat, it is avoided that the rotation angle of the rotating seat is too large, thereby avoiding the problem of inaccurate clamping position of the clamping head when clamping the bag blank again.

[0052] As described in the background technology, the conveying device of the paper bag machine in the prior art needs to clamp both sides of the bag blank during the process of conveying the bag blank, so multiple clamping mechanisms are set on both sides of the conveying device. However, with the increasing demand for miniaturization of paper bag machines, the structure of the paper bag machine is designed to be relatively compact, so that after the clamping mechanism is installed on both sides of the conveying device, its own position is not limited. Therefore, when the conveying device conveys the bag blank, the power mechanism needs to transmit power, and the conveying mechanism will shake slightly, thereby linking the clamping mechanism to shake, causing the clamping mechanism to collide with the structure on the paper bag machine such as the frame, making the paper bag machine noisy when producing paper bags.

[0053] In order to solve the above problems, the utility model provides a conveying mechanism of a paper bag machine, comprising a conveying assembly movably mounted on a frame, a limiting assembly fixedly mounted on the frame and located on a corresponding side of the conveying assembly in the width direction of the conveying assembly, and at least one side clamp assembly spaced apart along the conveying direction of the conveying assembly on a corresponding side of the conveying assembly and slidably connected to the limiting assembly; wherein, a limiting track is provided on the side of the limiting assembly close to the conveying assembly, and a rolling member is provided at one end of each side clamp assembly that is rollably adapted to fit within the limiting track; in the process of conveying the bag blanks, the conveying mechanism of this paper bag machine, because one end of the side clamp assembly rolls within the limiting track of the limiting assembly by providing the rolling member, the position of the side clamp assembly is limited by the limiting assembly, even if the conveying assembly shakes when the power mechanism transmits power during the process of conveying the bag blanks, the side clamp assembly will not collide with other mechanisms on the paper bag machine, such as the frame, to generate noise.

[0054] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0055] like Figure 1 and Figure 2 As shown, this embodiment provides a conveying mechanism 1 of a paper bag machine, which is used to convey the bag blanks to various processing mechanisms of the paper bag machine for processing along the production direction of the paper bags during the production process.

[0056] Specifically, the conveying mechanism 1 includes a conveying assembly 2 movably mounted on a frame 10, a limiting assembly 3 fixedly mounted on the frame 10 and located on one side of the conveying assembly 2 in the width direction of the conveying assembly 2, and at least one side clamp assembly 4 spaced apart along the conveying direction of the conveying assembly 2 on one side of the conveying assembly 2, each side clamp assembly 4 is slidably connected to the limiting assembly 3; when the blank is conveyed to the input end of the conveying assembly 2, the side clamp assembly 4 clamps the corresponding side of the blank so that the position of the blank will not shift during the conveying process. It should be understood that Figure 1 The right side of the figure also has a frame 10, so that the overall structure of the conveying structure 1 can be seen clearly. Figure 1 The frame 10 on the right side is not shown; and the width direction of the conveying assembly 2 is Figure 1 The arrow marked W in the figure points to the direction.

[0057] Specifically, a limiting track 30 is provided on the side of the limiting assembly 3 near the conveyor assembly 2. Each side clamp assembly 4 is provided at one end with a rolling member 41 that rolls within the limiting track 30. When the side clamp assembly 4 grips the bag blank and moves with the conveyor assembly 2, the rolling member 41 moves within the limiting track 30, thereby limiting the position of the side clamp assembly 4 and preventing the side clamp assembly 4 from colliding with other structures on the paper bag machine and generating noise. It should be understood that the number of side clamp assemblies 4 can be set to 1, 2, 4, etc., and this embodiment is not limited thereto.

[0058] Specifically, along the conveying direction of the bag blank, the limiting track 30 is sequentially formed with a drive clamping section 32 and a drive release section 33 from the input end of the conveying component 2 to the output end of the conveying component 2; wherein, when the bag blank is conveyed to the input end of the conveying component 2, the rolling member 41 enters the drive clamping section 32, and the linked side clamping component 4 clamps the corresponding side of the bag blank on the conveying component 2; and, when the bag blank is conveyed to the output end of the conveying component 2 along the conveying direction, the rolling member 41 enters the drive release section 33, and the linked side clamping component 4 releases the corresponding side of the bag blank. It should be noted that the side clamp assembly 4 can be provided on both sides of the conveying assembly 2 in the width direction, so that the bag blank is clamped on both sides in the width direction of the conveying assembly 2; or, since the bag blank needs to be processed with the bottom opened on the downstream side in the conveying direction during processing, the side clamp assembly 4 can also be provided on only one side in the width direction of the conveying assembly 2, and it is only necessary to design the length of the clamping head 421 to be larger in the width direction of the conveying assembly 2, so that the bag blank is clamped on the upstream side in the conveying direction, and the bottom can be opened on the downstream side.

[0059] More specifically, the working principle of this conveying mechanism 1 is as follows: during the operation of this conveying mechanism 1, when the sheet material enters the input end of the conveying component 2, the rolling member 41 enters the driving clamping section 32 of the limiting track 30, thereby linking the side clamping component 4 to clamp the corresponding side of the bag blank on the conveying component 2, so that during the processing of the bag blank, the position of the bag blank will not shift, thereby ensuring the reliability of the bag blank processing; then, the conveying component 2 continues to convey the bag blank along the conveying direction, and during this process, the rolling member 41 continues to move in the driving clamping section 32 of the limiting track 30, so that the bag blank is continuously clamped on the conveying surface of the conveying component 2 until the bag blank is processed. The rolling member 41 enters the driving release section 33, thereby linking the side clamping component 4 to release the processed bag blank, and then the processed bag blank is collected.

[0060] It can be seen that in the process of conveying the bag blanks of the conveying mechanism 1 of this paper bag machine, one end of the side clamp assembly 4 rolls in the limiting track 30 of the limiting assembly 3 by setting the rolling member 41, so that the position of the side clamp assembly 4 is limited by the limiting assembly 3. Even if the conveying assembly 2 shakes when the power mechanism transmits power during the process of conveying the bag blanks, the side clamp assembly 4 will not collide with other mechanisms on the paper bag machine such as the frame 10 to generate noise, thereby reducing the noise of the paper bag machine during operation, and further reducing the noise in the paper bag machine production workshop, providing a good working environment for the workshop staff, and contributing to the physical and mental health of the staff.

[0061] In addition, during the operation of this conveying mechanism 1, the rolling member 41 is cleverly designed to move within the driving clamping section 32 or the driving releasing section 33 of the limiting track 30 to realize the linkage side clamping or releasing of the bag blank by the side clamping assembly 4, without the need to set a driving motor to drive the side clamping assembly 4. Therefore, this conveying mechanism 1 also has the advantages of simple structure and low manufacturing cost.

[0062] Furthermore, the structure and arrangement of the conveying assembly 2, the limiting assembly 3, and the side clamp assembly 4 are further explained below.

[0063] In one embodiment, Figure 1 and Figure 2 As shown, the conveyor assembly 2 includes a drive component mounted on the frame 10, a rotating roller 21 disposed along the width of the frame 10 and rotatably connected to the frame 10, and a conveyor hub 20 fixedly mounted on the rotating roller 21. When conveying the blanks, the drive component drives the rotating roller 21 to rotate, thereby driving the conveyor hub 20 to rotate and convey the blanks. Compared to the prior art method of conveying blanks by providing a conveyor belt, the conveyor hub 20 in this application takes up less installation space in the paper bag machine along the length direction.

[0064] Specifically, the structure and arrangement of the driving component are not limited. For example, it can be a driving motor installed on the frame 10 and connected to the rotating roller 21. This embodiment does not limit this.

[0065] Of course, the conveying component 2 can also be configured to include a rotating shaft arranged along the width direction and rotatably connected to the frame 10, and an electric motor installed on the frame 10 and connected to the drive shaft for driving the rotating shaft to rotate, as well as a rotating wheel fixedly mounted on the rotating shaft and a conveyor belt fixedly mounted on the outer peripheral surface of the rotating wheel; this embodiment does not make a sole limitation on the structure and setting method of the conveying component 2.

[0066] Furthermore, if Figure 2 As shown, the limiting component 3 is configured as a circular base 31 which is coaxially arranged relative to the conveying hub 20 in the width direction and located on the corresponding side of the conveying hub 20; wherein, the limiting track 30 is arranged on the side close to the conveying hub 20 along the circumference of the circular base 31 and opens toward the side of the conveying hub 20; the limiting component 3 is configured as a circular base 31 so as to be adaptable to the conveying path of the conveying hub 20, and the limiting track 30 is arranged on the side close to the conveying hub 20, so as to facilitate the installation of the rolling member 41 into the limiting track 30, and the space occupied in the width direction of the conveying component 2 is small.

[0067] The following further explains the arrangement of the limiting track 30 on the circular base 31.

[0068] like Figure 4 As shown, the driving clamping section 32 and the driving releasing section 33 of the limiting track 30 are arranged in sequence and continuously along the circumference of the circular base 31; thereby, the rolling member 41 can smoothly move from the driving clamping section 32 to the driving releasing section 33. Furthermore, by providing the limiting track 30 on the circular base 31, it is possible to drive the side clamp assembly 4, so that the side clamp assembly 4 clamps or releases the bag blank, and it is also possible to limit the side clamp assembly 4, thereby reducing noise during operation of the conveying mechanism 1; thus, this conveying mechanism 1 has the advantages of simple structure and easy maintenance.

[0069] Specifically, when viewed along the width direction, one end of the drive clamping section 32 is opposite to the input end of the conveying hub 20, and the other end is opposite to the output end of the conveying hub 20, and the two ends of the drive release section 33 are respectively connected to the two ends of the drive clamping section 32; and the radial dimension of the drive clamping section 32 is larger than the radial dimension of the drive release section 33.

[0070] More specifically, since the radial dimension of the drive clamping section 32 is greater than the radial dimension of the drive release section 33, when the sheet enters the input end of the conveying assembly 2 and the rolling member 41 enters the drive clamping section 32 of the limiting track 30, the side clamping assembly 4 can be linked to move toward the outer peripheral surface close to the conveying hub 20, thereby clamping the corresponding side of the bag blank on the outer peripheral surface of the conveying hub 20. After the bag blank is processed, the rolling member 41 enters the drive release section 33, thereby linking the side clamping assembly 4 to move toward the outer peripheral surface away from the conveying hub 20 to release the processed bag blank; in this process, the rolling member 41 is limited by the drive clamping section 32 and the drive release section 33, thereby reducing the risk of collision between the side clamping assembly 4 and other structures on the paper bag machine (such as the frame 10), thereby making the paper bag machine less noisy when working.

[0071] Furthermore, the structure and arrangement of the side clip assembly 4 are described.

[0072] like Figure 3 and Figure 5 As shown, the side clamp assembly 4 includes a mounting frame 40 fixedly mounted on the corresponding side of the conveying hub 20 in the width direction, and a clamping component 42 and a transmission component 43 mounted on the mounting frame 40, wherein one end of the transmission component 43 is provided with a rolling member 41, and the other end is transmission-connected to the clamping component 42; and, when the bag blank is conveyed to the input end of the conveying hub 20, the rolling member 41 enters the driving clamping section 32, and the end of the clamping component 42 is linked by the transmission component 43 to clamp the corresponding side of the bag blank on the outer peripheral surface of the conveying hub 20, so that the position of the bag blank will not be easily shifted during the conveying process, so that the processed paper bags have higher quality.

[0073] Optionally, in one embodiment, the mounting bracket 40 includes a first connecting seat 400 fixedly mounted on a corresponding side of the conveying hub 20 in the width direction, and a second connecting seat 401 fixedly mounted on a side of the first connecting seat 400 close to the limiting assembly 3 .

[0074] Specifically, the clamping member 42 is rotatably connected to the first connecting seat 400, can swing around the conveying direction, and the end portion can switch between a clamping position and a release position relative to the outer circumference of the conveying hub 20. The transmission member 43 is movably arranged on the second connecting seat 401, can move along the height direction of the mounting frame 40 with the rolling member 41, and can link the clamping member 42 to swing around the conveying direction. It should be understood that the height direction of the mounting frame 40 is Figure 5 The length direction of the mounting frame 40 is Figure 5 The arrow marked L in the figure points to the direction.

[0075] More specifically, when the sheet material enters the input end of the conveying assembly 2 and the rolling member 41 enters the driving clamping section 32 of the limiting track 30, the transmission component 43 can be linked to move toward the direction close to the outer peripheral surface of the conveying hub 20, and drive the clamping component 42 to swing relative to the first connecting seat 400 toward the direction close to the outer peripheral surface of the conveying hub 20 and clamp the bag blank on the outer peripheral surface of the conveying hub 20; when the bag blank processing is completed, the rolling member 41 enters the driving release section 33, the transmission component 43 can be linked to move toward the direction away from the outer peripheral surface of the conveying hub 20, and drive the clamping component 42 to swing relative to the first connecting seat 400 toward the direction away from the outer peripheral surface of the conveying hub 20 and release the bag blank; in this process, the clamping component 42 clamps or releases the bag blank by swinging, so no relative friction occurs between the bag blank, thereby avoiding the problem of the position of the bag blank being offset due to the relative friction between the two when the clamping component 42 clamps or releases the bag blank.

[0076] Specifically, the structure and configuration of the rolling member 41 are not limited, and may be, for example, a rolling wheel, a ball bearing, a sliding wheel, etc., which is not limited in this embodiment. For example, configuring the rolling member 41 as a rolling wheel can reduce the friction between the rolling member 41 and the limiting track 30 when sliding within the limiting track 30, further reducing the risk of the rolling member 41 and the limiting track 30 becoming stuck due to excessive friction, allowing the clamping component 42 to reliably clamp the bag blank.

[0077] The structure and arrangement of the transmission component 43 are further explained below.

[0078] Alternatively, in one embodiment, Figure 5As shown, a slide groove along the height direction is opened on one side of the second connecting seat 401, and the transmission component 43 includes a slide rod 430 extending along the height direction and slidingly connected in the slide groove, and a transmission rod 431 with one end transmission connected to the corresponding side of the slide rod 430 and the other end extending along the height direction and transmission connected to the clamping component 42, and the rolling wheel is rotatably connected to one end of the slide rod 430 close to the circular base 31 and is rollingly connected to the limiting track 30.

[0079] Specifically, when the sheet material enters the input end of the conveying hub 20 and the rolling wheel enters the driving clamping section 32 of the limiting track 30, the sliding rod 430 can be linked to move along the height direction toward the outer peripheral surface of the conveying hub 20 and the transmission rod 431 can be linked to move along the height direction, thereby driving the clamping component 42 to swing relative to the first connecting seat 400 through the transmission rod 431, and clamping the bag blank on the outer peripheral surface of the conveying hub 20. The clamping component 42 can clamp the bag blank through a simple structural setting. Therefore, this structural setting can reduce the manufacturing cost of the conveying component and facilitate maintenance.

[0080] More specifically, transmission limiters are provided at both ends of the transmission rod 431, which can effectively transmit the power applied by the rolling wheel to the slide rod 430 to the clamping component 42 via the transmission rod 431, providing an effective power source for the clamping component 42 to clamp or release the bag blank.

[0081] Specifically, the structure and arrangement of the transmission limiter are not limited.

[0082] Optionally, in a feasible implementation, as Figure 5 As shown, the transmission limiters at both ends of the transmission rod 431 are respectively set to the first internal threaded joint bearing 432 at one end of the transmission rod 431, and the second internal threaded joint bearing 433 at the other end; wherein, a connecting rod 434 is provided on the corresponding side of the sliding rod 430, one end of the connecting rod 434 is fixedly connected to the corresponding side of the sliding rod 430, and the other end extends toward one end of the transmission rod 431 and is fixedly connected to the inner ring of the first internal threaded joint bearing 432; one end of the transmission rod 431 is fixedly connected to the outer ring of the first internal threaded joint bearing 432, and the other end is fixedly connected to the inner ring of the second internal threaded joint bearing 433; and the corresponding end of the clamping component 42 is fixedly connected to the outer ring of the second internal threaded joint bearing 433.

[0083] By respectively arranging the first internal thread type spherical bearing 432 and the second internal thread type spherical bearing 433 at both ends of the transmission rod 431, on the one hand, the connection strength between the connecting rod 434 and one end of the transmission rod 431, and the other end of the transmission rod 431 and the clamping component 42 is guaranteed; on the other hand, since the spherical sliding structure of the first internal thread type spherical bearing 432 and the second internal thread type spherical bearing 433 allows the inner ring to swing in any direction, the installation error between the connecting rod 434 and one end of the transmission rod 431, and the other end of the transmission rod 431 and the clamping component 42 can be compensated, thereby avoiding the connection rod 434 and one end of the transmission rod 431, and the other end of the transmission rod 431 and the clamping component 42 from being stuck, thereby ensuring the continuity of power transmission.

[0084] Optionally, in a feasible implementation, a limiting plate 403 is further provided on the second connecting seat 401 , and the limiting plate 403 is covered in the sliding groove and fixedly connected to the second connecting seat 401 .

[0085] Specifically, the slide rod 430 is limited by setting a limit plate 403, so that the slide rod 430 will not fall out of the slide groove during the movement in the slide groove; when the conveying hub 20 suddenly stops running, the slide rod 430 will not fall out of the slide groove due to the action of inertia; and when the slide rod 430 is subjected to the centrifugal force of the rotation of the conveying hub 20, the risk of the slide rod 430 falling out of the slide groove can also be reduced by the limit plate 403.

[0086] The structure and arrangement of the clamping component 42 are further explained below.

[0087] like Figure 5 As shown, the clamping component 42 includes a rotating seat 420 rotatably connected to the first connecting seat 400, a clamping head 421 having one end fixedly connected to the rotating seat 420 and the other end extending along the height direction toward the conveying surface of the conveying hub 20, and a connecting rod 422 having one end fixedly connected to the rotating seat 420 and the other end extending along the width direction and fixedly connected to the outer ring of the second internal threaded joint bearing 433.

[0088] Specifically, Figure 5The overall structural diagram of the middle side clamp assembly 4 is used to illustrate the working principle of the side clamp assembly 4. When the bag blank enters the input end of the conveying hub 20, the rolling wheel enters the driving clamping section 32 of the limiting track 30, and the rolling wheel links the sliding rod 430 to move along the height direction toward the outer circumference close to the conveying hub 20 and links the connecting rod 434 to move along the height direction, thereby driving the transmission rod 431 to move along the height direction through the connecting rod 434 and push one end of the connecting rod 422, and then the connecting rod 422 rotates on the linkage rotating seat 420 relative to the first connecting seat 400 close to the outer circumference of the conveying hub 20, and makes the clamping head 421 swing toward the direction close to the outer circumference of the conveying hub 20, and the bag blank is clamped on the outer circumference of the conveying hub 20 by the clamping head 421.

[0089] More specifically, when the bag blank enters the output end of the conveying hub 20, the rolling wheel enters the driving release section 33 of the limiting track 30, and the rolling wheel links the slide rod 430 to move in the height direction toward the outer circumference away from the conveying hub 20 and links the connecting rod 434 to move in the height direction away from the conveying hub 20, thereby driving the transmission rod 431 to move in the height direction through the connecting rod 434 and pulling one end of the connecting rod 422, and then the connecting rod 422 links the rotating seat 420 to rotate relative to the first connecting seat 400 away from the outer circumference of the conveying hub 20, and makes the clamping head 421 swing in the direction away from the outer circumference of the conveying hub 20, and the clamping head 421 releases the processed bag blank clamped on the outer circumference of the conveying hub 20.

[0090] Optionally, in a feasible implementation, as Figure 5 As shown, a limiting rod 423 is provided on the rotating seat 420 along the length direction of the mounting frame 40, which passes through the rotating seat 420; and both ends of the limiting rod 423 extend out of the rotating seat 420 respectively, and are opposite to the side of the first connecting seat 400 close to the second connecting seat 401 in the width direction.

[0091] Specifically, when the bag blank enters the output end of the conveying hub 20 and the rolling wheel enters the driving release section 33 of the limiting track 30, the linkage slide rod 430 moves in the height direction toward the outer circumference away from the conveying hub 20 and drives the transmission rod 431 to move in the height direction, thereby driving the rotating seat 420 to rotate relative to the first connecting seat 400 away from the outer circumference of the conveying hub 20 through the transmission rod 431, and causing the clamping head 421 to swing in the direction away from the outer circumference of the conveying hub 20 to release the processed bag blank; and by setting the limiting rod 423, the rotation angle of the rotating seat 420 can be limited, thereby avoiding the problem of the rotating seat 420 having an inaccurate clamping position when the clamping head 421 clamps the bag blank again due to excessive rotation angle.
