Description
Technical Field
[0001] This utility model relates to the field of machinery, and in particular to a dust extraction duct adjustment component. Background Technology
[0002] In the current packaging bag manufacturing industry, to ensure the cleanliness of the packaging bag surface, it is usually necessary to install a dust collection device to remove dust from the surface of the packaging bag. Common dust collection devices are stationary during operation, while the packaging bags are usually moved under the drive of a drive roller, and the dust collection device picks up the dust from the surface of the moving packaging bags.
[0003] In existing stationary vacuum cleaners, adjusting the distance between the vacuum cleaner's suction duct and the packaging bag on the drive roller is typically necessary to regulate the suction force and control the vacuuming effect for different packaging bags. For example, when the suction direction of the suction duct is perpendicular to the packaging bag surface, and the adjustable direction of the suction duct is also perpendicular to the packaging bag surface, driving the suction duct to move perpendicular to the packaging bag surface quickly adjusts the suction force. Conversely, when the suction direction of the suction duct is inclined to the packaging bag surface, and the adjustable direction of the suction duct is horizontal, while the packaging bag's movement direction is inclined to the horizontal plane, moving the suction duct changes the distance between it and the packaging bag surface, thus adjusting the suction force.
[0004] In existing fixed dust collection devices, the position of the packaging bags on the drive roller may vary depending on the dust collection requirements of different packaging bags. For example, some packaging bags may be located in the middle of the drive roller, while others may be located slightly to the left of the middle of the drive roller. Therefore, the dust collection duct may also be adjusted to move in a direction parallel to the plane where the packaging bags are located in order to meet the production needs of different packaging bags.
[0005] However, existing dust extraction duct adjustment components are relatively complex in structure and do not change the usage. Utility Model Content
[0006] To address the problems existing in the prior art, this utility model discloses a dust extraction duct adjustment component, which has a simple structure and is easy to adjust.
[0007] The objective of this utility model is achieved through the following technical solution: A dust extraction duct adjustment assembly is disposed between a frame and a dust extraction duct. It includes an adjustment block connected to the frame, an adjustment block having a through groove and adjustment portions disposed on both sides of the through groove. Each adjustment portion includes a through hole communicating with the through groove, a first rod disposed in the through hole and entering the through groove and movable, and a second rod disposed in the through groove that is displaced by the movement of the first rod. The first rod abuts against the second rod, and the second rod is connected to the dust extraction duct.
[0008] Furthermore, the adjustment blocks are provided on both sides of the dust extraction duct.
[0009] Furthermore, the through groove is a strip-shaped groove, and the length direction of the through groove is perpendicular to the axial direction of the second rod.
[0010] Furthermore, the first rod is threadedly connected to the through hole.
[0011] Furthermore, the first rod is provided with a locking nut that is threadedly engaged with the first rod, and the locking nut abuts against the outer wall of the adjusting block.
[0012] Furthermore, the second rod is detachably connected to the dust extraction duct.
[0013] Furthermore, the second rod is a bolt, and the nut of the second rod and the dust extraction duct are located on both sides of the first rod, respectively.
[0014] Furthermore, the through groove, the adjusting part, and the second rod constitute an adjusting module, and at least two adjusting modules are provided on a single adjusting block.
[0015] Furthermore, on a single adjustment block, the connection point between the adjustment block and the frame is located between adjacent adjustment modules.
[0016] Furthermore, the edges of the adjustment block are chamfered.
[0017] Compared with the prior art, the advantages of this utility model are as follows: by setting the through groove, adjusting the position of the first rod can drive the second rod to move along the length of the through groove, thereby adjusting the position of the dust suction duct. The structure is simple and the adjustment is convenient. At the same time, both first rods abut against the second rod, and the second rod is firmly clamped by the two first rods, so that the position of the dust suction duct is stable and fixed without displacement of the first rod.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0023] like Figures 1 to 3 As shown, this utility model discloses a dust suction duct adjustment component for use in an automatic packaging bag production device. The automatic packaging bag production device includes a frame 1, a dust suction duct 2, and a drive roller for driving the packaging bags. The dust suction duct 2 is used to absorb dust from the surface of the packaging bags located on the drive roller. The dust suction duct adjustment component of this utility model is disposed between the frame 1 and the dust suction duct 2. Adjusting the dust suction duct adjustment component of this utility model allows for adjustment of the position of the dust suction duct 2.
[0024] Detailed, such as Figure 2 and Figure 3 As shown, the dust extraction duct adjustment assembly includes an adjustment block 3 bolted to the frame 1. The adjustment block 3 is plate-shaped and has a through groove and adjustment parts on both sides of the through groove. Each adjustment part includes a through hole communicating with the through groove and a movable first rod 4. The first rod 4 enters the through groove through the through hole. Because adjustment parts are provided on both sides of the through groove, each through groove has at least two first rods 4. If each side of the through groove has two through holes, and each through hole has two first rods 4, then each through groove has eight first rods 4. The following detailed description uses the example of each side of the through groove having one through hole, and each through hole having one first rod 4. Figure 3 As shown, two first rods 4 enter the through groove from both ends. A second rod 5 is provided inside the through groove and is connected to the suction duct 2. The second rod 5 is located between the two first rods 4, and the first rods 4 abut against the second rod 5. Therefore, when the two first rods 4 are fixed, the second rod 5 is firmly held by the two first rods 4, thus stabilizing the position of the suction duct 2. When it is necessary to adjust the position of the suction duct 2, one of the first rods 4 is first moved along the length of the through groove, specifically, one of the first rods 4 is driven to move away from the second rod 5, increasing the gap between the two first rods 4. Then, the second rod 5 is moved towards the already moved first rod 4 and abuts against it, creating a gap between the second rod 5 and the other first rod 4. Finally, the other first rod 4 is moved so that it abuts against the second rod 5, thus completing the movement of the second rod 5 and the movement of the suction duct 2.
[0025] Since the second rod 5 moves within the through groove, the shape and orientation of the through groove determine the direction of movement of the suction duct 2. For example, if the length of the through groove is perpendicular to the plane of the packaging bag, moving the second rod 5 can quickly adjust the distance between the suction duct 2 and the packaging bag. Similarly, if the length of the through groove is inclined to the plane of the packaging bag, moving the second rod 5 can also adjust the distance between the suction duct 2 and the packaging bag. Furthermore, if the suction duct 2 is strip-shaped and the length of the through groove is parallel to the length of the suction duct 2, moving the second rod 5 can control the suction duct 2 to move along its length.
[0026] This invention utilizes a through-slot to adjust the position of the first rod 4, which in turn moves the second rod 5 along the length of the through-slot. This adjusts the position of the suction duct 2, thereby adjusting the relative position of the suction duct 2 and the packaging bag located on the drive roller, meeting the suction needs of different packaging bags. The suction duct adjustment component of this invention has a simple structure and is easy to adjust.
[0027] In the dust extraction duct adjustment component of this utility model, many technical features such as the number of adjustment blocks and the shape of the through groove have multiple implementations. Below, for each of these technical features, including the number of adjustment blocks, one implementation is selected for detailed description. The embodiment in which this implementation is located is referred to as this embodiment. Other implementations of the numerous features such as the number of adjustment blocks are referred to as other embodiments, which are briefly described below.
[0028] In this embodiment, as Figure 1 and Figure 2 As shown, adjusting blocks 3 are provided on both sides of the dust suction duct 2. The beneficial effect of this invention is particularly pronounced when the length of the through groove is perpendicular to the surface of the packaging bag, thanks to the two adjusting blocks 3. In this case, operating the first rod 4 on each of the two adjusting blocks 3 causes the second rods 5 on both sides of the dust suction duct 2 to move in the same direction and by the same distance, thus causing the dust suction duct 2 to translate. Alternatively, operating the first rod 4 on each of the two adjusting blocks 3 can cause them to move with different displacements and / or directions, thus causing the dust suction duct 2 to rotate. This mainly occurs when adjusting the inclination of the drive roller conveying the packaging bag, providing an adaptive adjustment to the dust suction duct 2. Therefore, this invention increases the adjustment range of the dust suction duct 2 by providing adjusting blocks 3 on both sides of the dust suction duct 2. In other embodiments, an adjusting block 3 may be provided at one end of the dust suction duct 2, and a pulley may be provided at the other end of the dust suction duct 2. When the length direction of the through groove is set along the direction perpendicular to the surface of the packaging bag, the second rod 5 is moved and the pulley slides synchronously. At this time, the dust suction duct 2 can only move horizontally.
[0029] In this embodiment, as Figure 3 As shown, the through groove is a strip-shaped groove, with its length direction perpendicular to the axis of the second rod 5. The dust extraction duct 2 is also strip-shaped, with the axis of the second rod 5 parallel to the length direction of the dust extraction duct 2. Both the length direction of the through groove and the axis of the second rod 5 lie in a plane parallel to the horizontal plane. When the second rods 5 at both ends of the dust extraction duct 2 move in the same direction and with the same displacement along the length direction of the through groove, the dust extraction duct 2 is translated along the length direction of the through groove. When the suction direction of the dust extraction duct 2 is set along the length direction of the through groove, and when the plane where the packaging bag is located is perpendicular to the suction direction of the dust extraction duct 2, the suction force of the dust extraction duct 2 on the packaging bag can be quickly adjusted by adjusting the amount of translation along the length direction of the through groove. In other embodiments, depending on the production requirements of different packaging bags and the adjustment requirements of the position of the dust extraction duct 2, the through groove can also be arc-shaped, in which case the first rod 4 is a flexible rod.
[0030] In this embodiment, as Figure 3As shown, the adjusting block 3 is plate-shaped, with a through groove penetrating the plate planes on opposite sides of the adjusting block 3, and a through hole penetrating the side wall surface of the adjusting block 3 and the through groove. A first rod 4 is threadedly connected to the through hole, with the axis of the through hole coinciding with the center line of the through groove in the length direction. Therefore, rotating the first rod 4 allows it to move along the through groove in the length direction, thereby controlling the length of the first rod 4 entering the through groove. This invention facilitates the adjustment of the first rod 4's movement by threading it to the through hole, and due to the threaded connection, the first rod 4 is not easily moved during the operation of the dust extraction duct 2. In other embodiments, the first rod 4 is clearance-fitted to the through hole, but several grooves are provided on the first rod 4, and the adjusting block 3 is provided with locking blocks that mate with the grooves; the first rod 4 and the adjusting block 3 are fixed by the engagement of the locking blocks with different grooves.
[0031] In this embodiment, as Figure 3 As shown, the first rod 4 is provided with a locking nut 6 that is threadedly engaged with the first rod 4, and the locking nut 6 abuts against the outer wall of the adjusting block 3. When it is necessary to adjust the movement of the first rod 4, first rotate the locking nut 6 to create a gap between the locking nut 6 and the side wall of the adjusting block 3, and then rotate the first rod 4. When the first rod 4 is adjusted to a suitable position, rotate the locking nut 6 again to make it abut against the side wall of the adjusting block 3. This utility model, through the setting of the locking nut 6, forms a double nut locking structure with the locking nut 6 and the threaded through hole relative to the first rod 4, making the first rod 4 less likely to move during the operation of the dust collection duct 2. In other embodiments, the adjusting block 3 and the first rod 4 can also adopt the above-mentioned slot and block engagement to make the first rod 4 less likely to move during the operation of the dust collection duct 2.
[0032] In this embodiment, as Figure 2 As shown, after prolonged operation, the dust collection duct 2 accumulates a significant amount of dust and requires cleaning. Therefore, the second rod 5 is detachably connected to the dust collection duct 2, allowing for separation between the duct 2 and the second rod 5 before cleaning. There are various methods of detachable connection, such as threaded connections, snap-fit connections, and magnetic connections. In other embodiments, the second rod 5 can also be welded to the dust collection duct 2; in this case, the dust collection duct 2 would need to be cleaned within the automated packaging bag production device.
[0033] In this embodiment, as Figure 2 and Figure 3As shown, the second rod 5 is a bolt, therefore the second rod 5 is also connected to the suction duct 2 by a thread, i.e., a detachable connection by a thread. The nut of the second rod 5 and the suction duct 2 are located on opposite sides of the first rod 4, with the first rod 4 abutting against the body of the second rod 5, and the nut of the second rod 5 located on the side of the first rod 4 furthest from the suction duct 2. In this case, the nut of the second rod 5 facilitates the separation or connection of the second rod 5 to the suction duct 2, and also serves as a limiting element. Because the suction duct 2 vibrates during operation, if the second rod 5 were a screw, it might move along its axis under the vibration of the suction duct 2, potentially causing it to detach from the through groove, leading to abnormal separation of the suction duct 2 and the adjusting block 3. The nut on the second rod 5 effectively prevents it from coming out of the through groove. In other embodiments, an anti-slip pad can also be provided at the end of the first rod 4 that abuts against the second rod 5.
[0034] In this embodiment, as Figure 3 As shown, the through groove, the adjusting part, and the second rod 5 together form an adjusting module. At least two adjusting modules are provided on a single adjusting block 3, and each adjusting module is equally spaced along the length direction perpendicular to the through groove, with the length directions of the through grooves in each adjusting module being parallel to each other. Since the volume of the suction duct 2 is usually large, this invention, through the arrangement of multiple adjusting modules, allows multiple second rods 5 to connect the suction duct 2 and the adjusting block 3, effectively enhancing the connection strength between the suction duct 2 and the adjusting block 3. In other embodiments, only one adjusting module may be provided on a single adjusting block 3, but the radial cross-sectional area of the second rod 5 is larger to ensure that the second rod 5 has sufficient strength and rigidity.
[0035] In this embodiment, as Figure 3 As shown, on a single adjusting block 3, the connection point between the adjusting block 3 and the frame 1 is located between adjacent adjusting modules, that is, the connection point between the adjusting block 3 and the frame 1 is located between two adjacent through slots. This makes the force on the adjusting block 3 more uniform and less prone to bending and deformation. In other embodiments, the connection point between the adjusting block 3 and the frame 1 can also be set to be on the same side of each through slot. However, in this case, due to the large gaps in the through slots, the overall rigidity of the adjusting block 3 is lower, and the force applied at the connection point between the adjusting block 3 and the frame 1 is more likely to cause deformation of the adjusting block 3.
[0036] In this embodiment, as Figure 3 As shown, the adjusting block 3 is rectangular in shape, and its edges are chamfered 7. This invention uses the chamfered edges 7 to prevent the edges of the adjusting block 3 from scratching the human body during the rotation of the first lever 4 or the second lever 5. In other embodiments, the adjusting block 3 may also be circular.
[0037] In summary, the dust extraction duct adjustment component of this utility model, through the setting of the through groove, allows adjustment of the position of the first rod 4, which in turn drives the second rod 5 to move along the length of the through groove, thereby adjusting the position of the dust extraction duct 2. The structure is simple and the adjustment is convenient. Furthermore, by setting adjustment blocks 3 on both sides of the dust extraction duct 2, the adjustment range of the dust extraction duct 2 is increased. The through groove is designed as a strip-shaped groove, facilitating quick adjustment of the suction force of the dust extraction duct 2 on the packaging bag. The threaded connection between the first rod 4 and the through hole facilitates adjustment of the first rod 4's movement, and the first rod 4 is not easily moved during the operation of the dust extraction duct 2. The locking nut 6 forms a double-nut locking structure with the threaded through hole relative to the first rod 4. The second rod 5 is detachably connected to the dust extraction duct 2, facilitating cleaning operations. The second rod 5 is designed as a bolt, and the nut on the second rod 5 effectively prevents the second rod 5 from coming out of the through groove. By incorporating multiple adjustment modules, the connection strength between the suction duct 2 and the adjustment block 3 is effectively enhanced. Furthermore, by positioning the connection point between the adjustment block 3 and the frame 1 between adjacent adjustment modules on a single adjustment block 3, the adjustment block 3 is less prone to bending and deformation. Finally, the chamfered corner 7 prevents the edges of the adjustment block 3 from scratching the user.
[0038] It should be emphasized that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
