Dust removal mechanism for carton processing

Abstract

The utility model relates to the technical field of carton processing equipment, in particular to a dust removal mechanism for carton processing. According to the carton processing dust removal mechanism provided by the embodiment of the invention, the to-be-cut corrugated board is fixed to the workbench, and the driving device is started to enable the first lead screw to rotate. And under the condition that the first lead screw rotates, the cutting assembly can be driven by the first nut base to do linear motion, and therefore the cutting treatment process is achieved. Meanwhile, a first bevel gear fixed to the first lead screw can drive the second lead screw to rotate through a bevel gear transmission mechanism. Due to the fact that the rotating direction of a thread-shaped thread of the first lead screw is opposite to that of the second lead screw, a dust collector of the dust collection mechanism can be driven by a second nut seat to move opposite to the cutting mechanism. In this way, the dust collection mechanism can adsorb the chippings at the cutting position of the corrugated board through the dust collection opening of the dust collector, and therefore the problem that the chippings are accumulated around the material leakage holes to cause blockage is solved.

Description

Technical Field

[0001] This application relates to the field of cardboard box processing equipment technology, and more specifically, to a dust removal mechanism for cardboard box processing. Background Technology

[0002] Corrugated boxes are packaging products made from corrugated cardboard through die-cutting, creasing, stapling, or gluing. They are widely used in the transport packaging industry. Because corrugated cardboard needs to be made into corrugated boxes of different sizes, it needs to be cut into the required shapes and sizes, and then folded and stapled or glued to form complete corrugated boxes.

[0003] In related technologies, corrugated cardboard is typically placed on the worktable of a cutting machine and cut by moving cutting blades. During the actual cutting process, the multi-layered cardboard structure of the corrugated cardboard is subjected to compression and shearing action by the cutting blades, resulting in the formation of debris. Therefore, the worktable surface is usually equipped with drainage holes to facilitate the directional collection and processing of the debris.

[0004] However, the design of the discharge hole may cause debris to accumulate around it. This not only affects the cleanliness of the workbench but may also hinder debris collection, thus impacting the efficiency of debris collection. Utility Model Content

[0005] In view of this, embodiments of this application provide a dust removal mechanism for carton processing to solve the technical problem in the related art that debris generated during the cutting of corrugated cardboard may accumulate near the material discharge hole of the worktable.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] A dust removal mechanism for cardboard box processing includes:

[0008] The frame has a worktable at its top, with several material leakage holes evenly distributed in the central area of ​​the worktable along the thickness direction; a drive beam is arranged parallel above the worktable, and an open drive cavity extending along its length is formed inside the drive beam.

[0009] The first lead screw is horizontally rotatably disposed within the drive cavity, with its axial direction aligned with the length direction of the drive cavity; the end of the first lead screw extends outside the drive cavity and is coaxially connected to the output shaft of the drive device, which is disposed on the outer surface of the side plate of the drive beam; a first bevel gear is fixedly fitted at the input end of the first lead screw.

[0010] The second lead screw is horizontally rotatably positioned directly below the drive beam. Its thread direction is opposite to that of the first lead screw, but it has the same pitch. A second bevel tooth is fixedly fitted at the input end of the second lead screw, and the specifications of the second bevel tooth are the same as those of the first bevel tooth.

[0011] A bevel gear transmission mechanism, comprising a transmission rod and bevel gears disposed at both ends thereof. The transmission rod passes through the bottom plate of the drive beam and is connected to the first bevel gear and the second bevel gear respectively through the bevel gears at both ends thereof.

[0012] A cutting assembly, comprising a first nut seat threadedly connected to the first lead screw, the cutting assembly being threadedly connected to the first lead screw via the first nut seat, and the cutting blade of the cutting assembly acting on the table surface of the worktable;

[0013] The vacuuming mechanism includes a second nut seat sleeved on the second lead screw. The second nut seat is rigidly connected to a vacuum cleaner via a bracket. The vacuum cleaner's suction port faces the cutting blade and maintains a preset distance from the material leakage hole.

[0014] Among the possible implementation methods is a straight track;

[0015] The linear track is symmetrically arranged on the two side walls of the workbench in the width direction. The bottom of both ends of the drive beam is provided with sliders that match the linear track. The drive beam is slidably arranged in the linear track of the workbench through the sliders.

[0016] In some possible implementations, the cutting assembly is fixedly connected to the first nut seat by a detachable bolt.

[0017] In some possible implementations, a column connected to the cutting assembly is vertically disposed on the top of the first nut seat, and a mounting plate is fixedly disposed on the top of the column. The mounting plate is connected to the cutting assembly along the thickness direction by bolts.

[0018] In some possible implementations, the direction of movement of the drive beam along the linear track is orthogonal to the direction of movement of the cutting assembly along the first lead screw axis.

[0019] In some possible implementations, a transmission bearing is also included, which is fixedly sleeved on the outside of the transmission rod;

[0020] The transmission bearing is fixedly mounted on the base plate of the drive beam via its outer ring, and the inner ring of the transmission bearing is fixedly connected to the outer wall of the transmission rod.

[0021] The dust removal mechanism for cardboard box processing provided in this application embodiment has at least the following beneficial effects:

[0022] In the cardboard processing dust removal mechanism provided in this embodiment, the corrugated cardboard to be cut is fixed on the worktable, and the drive device is activated to rotate the first lead screw. While the first lead screw is rotating, the cutting assembly moves linearly under the drive of the first nut seat, thus achieving the cutting process. Simultaneously, the first bevel gear fixed to the first lead screw drives the second lead screw to rotate via the bevel gear transmission mechanism. Since the thread direction of the first lead screw is opposite to that of the second lead screw, the vacuum cleaner of the dust collection mechanism moves in the opposite direction to the cutting mechanism under the drive of the second nut seat. In this way, the dust collection mechanism can absorb debris from the corrugated cardboard cutting position through the vacuum cleaner's suction port, thereby preventing debris from accumulating around the discharge hole and causing blockage.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figures 1-5 As shown in the embodiment of this application, the dust removal mechanism for cardboard processing includes a frame 100, a first lead screw 400, a second lead screw 600, a transmission mechanism, a cutting assembly 800, and a dust collection mechanism. The frame 100 is a hardware component used to support and install the various parts. A workbench 200 is bolted to the top of the frame 100. The workbench 200 serves as a carrier for cutting corrugated cardboard. Several material discharge holes 210 are distributed in the central area of ​​the workbench 200 surface, extending along the thickness direction. Debris generated during the cutting process can enter the workbench 200 through the material discharge holes 210, achieving directional collection of debris.

[0033] A drive beam 300 is also arranged parallel above the workbench 200. An open drive cavity 310 is formed inside the drive beam 300, which extends along the length of the drive beam 300. Furthermore, an open opening communicating with the drive cavity 310 is provided at the top of the drive beam 300.

[0034] The first lead screw 400 is a mechanical transmission element that converts rotary motion into linear motion. Both ends of the first lead screw 400 are rotatably equipped with first support seats, and the first lead screw 400 is mounted within the drive cavity 310 of the drive beam 300 via the first support seats. For example... Figure 2 and Figure 3As shown, the axial direction of the first lead screw 400 is consistent with the length direction of the drive cavity 310, and the end of the first lead screw 400 extends outside the drive cavity 310 and is connected to the drive device 500. The first lead screw 400 is coaxially connected to the output shaft of the drive device 500, and the drive device 500 is mounted on the outer surface of the side plate of the drive beam 300. Furthermore, a first bevel gear 410 is fitted onto the first lead screw 400 near the input end via a key connection.

[0035] Similarly, the second lead screw 600 is also a mechanical transmission element that converts rotary motion into linear motion. Both ends of the second lead screw 600 are rotatably equipped with second support seats, and the second lead screw 600 is mounted in the drive cavity 310 of the drive beam 300 via the second support seats. For example... Figure 4 As shown, the axial direction of the second lead screw 600 is consistent with the length direction of the drive cavity 310. A second bevel gear 610 is fitted at the input end of the second lead screw 600 via a key connection. The second bevel gear 610 is located directly below the first bevel gear 410, and the second bevel gear 610 has the same specifications as the first bevel gear 410. Furthermore, the thread direction of the second lead screw 600 is opposite to that of the first lead screw 400, and both have the same pitch.

[0036] In this embodiment, the bevel gear transmission mechanism consists of a transmission rod 700 and bevel gears 710 disposed at both ends of the transmission rod 700. Figure 4 As shown, the transmission rod 700 passes through and is rotatably connected to the base plate of the drive beam 300. The bevel gears 710 at both ends of the transmission rod 700 mesh with the first bevel gear 410 and the second bevel gear 610, respectively. Preferably, a transmission bearing 320 is provided at the base plate of the drive beam 300, and the transmission bearing 320 is sleeved outside the transmission rod 700. The outer ring of the transmission bearing 320 is fixedly connected to the base plate of the drive beam 300, and the inner ring of the transmission bearing 320 is fixedly connected to the transmission shaft, for example, by a key connection.

[0037] Continue as Figures 1-4 As shown, the cutting assembly 800 includes a first nut seat 820, which is threadedly connected to the first lead screw 400. The cutting assembly 800 achieves a threaded connection with the first lead screw 400 through the first nut seat 820. Therefore, starting the drive device 500 can drive the cutting blade 810 of the cutting assembly 800 to cut the corrugated cardboard fixed on the workbench 200.

[0038] Similarly, the vacuuming mechanism includes a second nut seat 910, which is rigidly connected to the vacuum cleaner 900 via a bracket. The second nut seat 910 is threaded onto the second lead screw 600, allowing the vacuum cleaner 900 to achieve a threaded connection with the second lead screw 600. Furthermore, the vacuum cleaner 900's suction port faces the cutting blade 810 of the cutting assembly 800 and maintains a predetermined distance from the material discharge hole 210 of the worktable 200, thus effectively adsorbing debris generated during the cutting process. Specifically, the bevel gear 710 of the transmission rod 700 has a module of 2 to ensure that the vacuum cleaner 900 and the cutting blade 810 can move towards each other at the same speed.

[0039] In the cardboard processing dust removal mechanism provided in this embodiment, the corrugated cardboard to be cut is fixed on the workbench 200, and the drive device 500 is activated to rotate the first lead screw 400. While the first lead screw 400 is rotating, the cutting assembly 800 moves linearly under the drive of the first nut seat 820, thus achieving the cutting process. Simultaneously, the first bevel gear 410 fixed to the first lead screw 400 drives the second lead screw 600 to rotate via the bevel gear transmission mechanism. Since the thread direction of the first lead screw 400 is opposite to that of the second lead screw 600, the vacuum cleaner 900 of the dust collection mechanism moves in the opposite direction to the cutting mechanism under the drive of the second nut seat 910. In this way, the dust collection mechanism can absorb debris from the corrugated cardboard cutting position through the suction port of the vacuum cleaner 900, thereby preventing debris from accumulating around the discharge hole 210 and causing blockage.

[0040] In some embodiments, such as Figure 1 As shown, linear tracks 220 are symmetrically arranged on the two sidewalls of the worktable 200 in the width direction, and the linear tracks 220 extend along the length direction of the worktable 200. Correspondingly, the bottom ends of the drive beam 300 are connected to the linear tracks 220 via sliders. Preferably, the sliders may include guide grooves matching the cross-sectional shape of the linear tracks 220, and linear bearings with built-in balls. This allows the drive beam 300 to move linearly on the worktable 200. Preferably, the direction of movement of the drive beam 300 along the linear tracks 220 is orthogonal to the direction of movement of the cutting assembly 800 along the axial direction of the first lead screw 400. That is, the cutting assembly 800 can achieve coordinated movement along the XY axes through the first lead screw 400 and the linear tracks 220 to meet practical needs.

[0041] In some embodiments, such as Figure 5As shown, a column 821 is fixedly mounted on the top of the first nut seat 820, and a mounting plate 822 is also provided on the top of the column 821. The first nut seat 820 is attached to the cutting assembly 800 through the mounting plate 822 and is connected by bolts. The structure with detachable bolt connection allows workers to easily disassemble and maintain the equipment in a timely manner.

[0042] Preferably, the cutting assembly 800 may also be provided with a height adjustment screw, thereby enabling the cutting blade 810 to adjust in the vertical direction to meet the cutting needs of corrugated cardboard of different thicknesses.
