Description

Technical Field

[0001] This utility model belongs to the field of cardboard processing technology, and in particular relates to a cardboard trimming device for packaging box production. Background Technology

[0002] According to the published patent CN221584667U, a cardboard trimming device for packaging box production includes a base and an outer shell fixedly installed on the base. A horizontally arranged through groove is formed between the outer shell and the base. Two sets of symmetrically arranged pulleys are installed in the through groove. The pulleys are used to transport the cardboard of the packaging box along the front-back direction of the through groove so that it passes through the through groove. This solves the problem of more burrs and debris appearing on the cut edges of the cardboard after cutting. However, the following shortcomings still exist:

[0003] The aforementioned equipment solves the problem of automatically dropping debris and waste into the receiving trough and cleaning it by pushing the plate. However, the cardboard may move during the trimming process, which may cause the blade to damage the cardboard surface, thus affecting the dimensional accuracy and edge neatness of the cardboard after trimming. This results in the cardboard not meeting the specifications required for packaging box production. Therefore, we propose a cardboard trimming device for packaging box production. Utility Model Content

[0004] The purpose of this utility model is to provide a cardboard trimming device for packaging box production. Through the limiting mechanism and the trimming mechanism, it solves the problem that the above-mentioned equipment can automatically drop debris and waste into the receiving trough and be carried out by the push plate for cleaning. However, the cardboard may move during trimming, which may cause the blade to damage the surface of the cardboard, thereby affecting the dimensional accuracy and edge neatness of the cardboard after trimming, resulting in the cardboard not meeting the specifications of packaging box production.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a cardboard trimming device for packaging box production, including a workbench, a support frame fixedly connected to the top outer wall of the workbench, a controller fixedly connected to the outer wall of the support frame, and a limit mechanism provided on the bottom outer wall of the workbench.

[0007] The limiting mechanism includes a motor mounting bracket, the outer wall of which is fixedly connected to the bottom outer wall of the worktable. A first motor is fixedly connected to the outer wall of the motor mounting bracket. A rotating shaft is fixedly connected to the bottom output end of the first motor via a coupling. A gear is fixedly connected to the outer wall of the rotating shaft at the end away from the first motor. A sliding groove is provided inside the worktable. Several slide rails are fixedly connected to the bottom outer wall of the worktable. Slide plates are slidably connected inside each of the slide rails. The outer wall of each slide plate at the end away from the slide rail is slidably connected to the inner wall of the sliding groove. Clamping plates are fixedly connected to the top outer wall of each slide plate.

[0008] Furthermore, a rack is fixedly connected to the outer wall of several of the slide plates, and the outer wall of several of the racks meshes with the outer wall of the gear. The outer wall of the support frame is provided with a trimming mechanism.

[0009] Furthermore, the trimming mechanism includes a motor fixing plate, the outer wall of which is fixedly connected to the outer wall of the support frame, and a second motor is fixedly connected to the outer wall of the motor fixing plate. The bottom output end of the second motor is fixedly connected to a rotating shaft via a coupling.

[0010] Furthermore, a synchronous pulley is fixedly connected to the outer wall of the end of the rotating shaft away from the second motor, and a synchronous belt is driven to the outer wall of the synchronous pulley.

[0011] Furthermore, a second synchronous pulley is connected to the outer wall of the synchronous belt, and a lead screw is fixedly connected to the inner wall of the second synchronous pulley.

[0012] Furthermore, the outer wall of the lead screw is threaded with a slider, and the inner wall of the support frame is provided with a second sliding groove.

[0013] Furthermore, the outer wall of the slider is slidably connected to the inner wall of the second groove, and an electric telescopic rod is fixedly connected to the bottom outer wall of the slider.

[0014] Furthermore, a cutter is fixedly connected to the bottom output end of the electric telescopic rod, and a cutting blade is fixedly connected to the bottom output end of the cutter.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a rotating shaft. When the shaft rotates, it drives a gear to rotate, which in turn drives two racks to move in alignment. These racks then move their connected slide plates along the same trajectory. The slide plates then slide along a rail, causing a clamping plate to slide within a groove. When the clamping plate contacts the cardboard, it is positioned and fixed, ensuring the cardboard does not move or wobble during trimming. This allows the trimming cutter to cut along a preset path, guaranteeing dimensional accuracy and edge smoothness, ensuring consistent packaging box dimensions, and improving product quality.

[0017] 2. This utility model incorporates a second synchronous wheel. When the second synchronous wheel starts to rotate, it drives the lead screw to rotate. When the lead screw starts to rotate, it drives the slider to move left and right. At this time, the slider drives the cutting blade to move along the same trajectory. Subsequently, the cutting blade can completely cut the edges and corners of the cardboard, achieving the effect of trimming the cardboard. This ensures that the length, width, diagonal, and other dimensions of the cardboard meet the design requirements of the packaging box, thereby making the produced packaging boxes uniform in size and standard in specifications, improving the overall quality and consistency of the product.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The outer wall of the support frame 101 is provided with a trimming mechanism 3.

[0029] The trimming mechanism 3 includes a motor fixing plate 301. The outer wall of the motor fixing plate 301 is fixedly connected to the outer wall of the support frame 101. A second motor 302 is fixedly connected to the outer wall of the motor fixing plate 301. The motor fixing plate 301 is used to limit and fix the second motor 302, making the second motor 302 more stable during use. The bottom output end of the second motor 302 is fixedly connected to a rotating shaft 303 via a coupling. A synchronous pulley 304 is fixedly connected to the outer wall of the end of the rotating shaft 303 away from the second motor 302. When the second motor 302 is in operation, the synchronous pulley 304 is fixedly connected to the outer wall of the end of the rotating shaft 303 away from the second motor 302.

[0031] One specific application of this embodiment is:

[0032] When the operator needs to use the equipment, the cardboard is first placed on the workbench 1. Then, the first motor 202 is started via the controller 102. When the first motor 202 starts running, it drives the rotating shaft 203 to rotate. When the rotating shaft 203 starts rotating, it drives the gear 204 to rotate. When the gear 204 starts rotating, it drives the two racks 209 to move in alignment. At this time, the two racks 209 drive their respective connected slide plates 207 to move along the same trajectory. The slide plates 207 then drive the clamping plates 208 to slide in the slide groove 205 via the slide rail 206. When the clamping plates 208 contact the cardboard, they limit and fix it. Then, the electric telescopic rod 310 is started via the controller 102. At this time, the electric telescopic rod 310 lowers the cutter 311 and the cutting blade 312 to the appropriate position. The device is set up, and then the cutter 311 is started. When the cutter 311 starts running, it drives the cutting blade 312 to rotate. When the cutting blade 312 contacts the cardboard, it cuts it. Then, the controller 102 starts the second motor 302. When the second motor 302 starts running, it drives the rotating shaft 303 to rotate. When the rotating shaft 303 starts rotating, it drives the synchronous pulley 304 to rotate. At this time, the synchronous pulley 304 drives the synchronous pulley 306 to rotate through the synchronous belt 305. When the synchronous pulley 306 starts rotating, it drives the lead screw 307 to rotate. When the lead screw 307 starts rotating, it drives the slider 308 to move left and right. At this time, the slider 308 drives the cutting blade 312 to move along the same trajectory. Then the cutting blade 312 can completely cut the corners of the cardboard.
