Description

Technical Field

[0001] This utility model relates to the field of slotting machine technology, and in particular to an adjustable slotting machine for carton processing. Background Technology

[0002] In the corrugated box processing industry, adjustable slotting machines are key equipment for achieving personalized corrugated box forming. Their core function is to cut slots for folding on cardboard by using adjustable-spacing cutting blades and corresponding lower die slots on the upper and lower rollers.

[0003] When changing products, personnel need to adjust the blade spacing. Currently, the common adjustment method in the industry is for the operator to activate the adjustment mechanism to control the cutting blade, using the contact between the blade sidewall and the inner wall of the lower roller groove to drive the entire tool holder unit for sliding positioning. Although this method is simple in structure, it has a significant drawback in practical applications: as the core component that directly performs the cutting function, the integrity of the cutting edge and the accuracy of its installation directly determine the grooving quality and production cost. However, during the lateral turning process, the force applied to the side of the blade can easily cause micro-chipping and hidden cracks in the carbide cutting edge. These damages will rapidly expand in subsequent high-speed cutting, causing the blade to become dull prematurely and its lifespan to be greatly shortened. Utility Model Content

[0004] (a) Technical problems to be solved In view of the above-mentioned shortcomings and deficiencies of the prior art, this utility model provides an adjustable slotting machine for carton processing, which solves the technical problem that in the existing slotting machine, the contact between the side wall of the blade and the inner wall of the lower roller groove drives the entire blade holder unit to slide and position. During the lateral movement, the force applied to the side of the blade can easily cause micro-chipping and hidden cracks in the cemented carbide cutting edge.

[0005] (II) Technical Solution To achieve the above objectives, the main technical solutions adopted by this utility model include: In a first aspect, this utility model provides an adjustable slotting machine for carton processing.

[0006] This utility model provides an adjustable slotting machine for carton processing, which includes a slotting machine body. The slotting machine body includes a first drive roller and a second drive roller that are arranged parallel to each other and can rotate synchronously in opposite directions. The surface of the first drive roller is detachably mounted with a processing disc that can slide laterally, and the surface of the processing disc is provided with blades; The second drive roller has a tool holder slider fixed on its surface, which matches the number and position of the processing discs. The tool holder slider has an embedding groove on its surface. The embedding groove is on the same vertical axis as the blade and the groove width is the same as the blade thickness. It also includes an auxiliary component disposed on the surface of the machining disk, which is used to replace the cutting tool in engaging with the insert groove during tool pitch adjustment.

[0007] Optionally, the auxiliary component includes: The mating plate has a thickness consistent with the width of the embedding groove, and one end near the embedding groove has an arc-shaped design, with the curvature of the arc-shaped end matching the curvature of the edge of the embedding groove.

[0008] Optionally, the auxiliary component further includes: A housing is fixed to the surface of the processing disc, and a mating plate is slidably installed inside the housing. A spring is fixedly connected to the inner wall of the housing, and the other end of the spring is fixedly connected to the mating plate.

[0009] Optionally, a connecting buckle is fixedly connected to the surface of the housing, and a connecting head is correspondingly provided on the surface of the mating plate. The connecting buckle can hook with the connecting head to lock the position of the mating plate.

[0010] Optionally, the auxiliary component further includes: A groove is formed on the surface of the processing tray, and a slide block is horizontally slidably connected in the groove. The side of the slide block closest to the housing is fixedly connected to the housing.

[0011] Optionally, it is characterized in that, The auxiliary components are provided in at least three, all of which are installed on the surface of the processing disc and are respectively located between two adjacent blades.

[0012] Optionally, the processing disc is detachably connected to the first drive roller by bolts, and the surface of the processing disc is provided with blade mounting holes for fixing the blade, and the blade is fixed to the surface of the processing disc by bolts.

[0013] Optionally, guide grooves are provided on both sides of the mating plate, and these guide grooves cooperate with the guide ribs inside the housing.

[0014] (III) Beneficial Effects The beneficial effects of this utility model are: By setting up an independent auxiliary component, when adjusting the blade distance, the mating plate replaces the cutting blade and the tool holder slider's embedded groove for meshing and transmission. This completely avoids the blade from being subjected to abnormal lateral thrust and friction, fundamentally solving problems such as chipping of the cutting edge and wear of the mounting reference surface caused by directly moving the blade. This protects expensive tools and significantly extends their service life. The auxiliary components can be flexibly adjusted in lateral position on the machining disk by sliding cooperation between the slide block and the machining disk groove. At least three auxiliary components are set and distributed between adjacent blades. No matter what angle the machining disk is rotated to, the tool holder slider can be adjusted synchronously by the nearest auxiliary component, avoiding delays in adjustment operation caused by machining disk angle issues.

Detailed Implementation

[0017] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper" and "lower" are used interchangeably with... Figure 1 The orientation is used as a reference.

[0018] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0019] like Figures 1 to 6As shown, this embodiment proposes an adjustable slotting machine for carton processing, including a slotting machine body 100. The slotting machine body 100 has a first drive roller 160 and a second drive roller 110 arranged vertically and parallel to each other. The two roller shafts are arranged in parallel and can achieve synchronous rotation in opposite directions (controlled by the machine's own drive device), providing stable power for carton conveying and slotting. The surface of the first drive roller 160 is used to install the processing disc 130, and the surface of the second drive roller 110 is used to install the knife holder slider 120. The positions of the two correspond one-to-one to ensure the accuracy of subsequent slotting.

[0020] The processing disc 130 is detachably mounted on the surface of the first drive roller 160 by bolts, and can slide laterally along the roller shaft to adjust the grooving spacing. Its surface is reserved with blade mounting holes for fixing the blade 140. The blade 140 is made of cemented carbide and is fixed to the surface of the processing disc 130 by bolts. The blade edge faces downwards towards the second drive roller 110, which is the core cutting component for grooving operations.

[0021] The tool holder slider 120 is fixed to the surface of the second drive roller 110, matching the number and position of the processing disk 130, and its surface is provided with an embedding groove 150.

[0022] The groove of the embedded groove 150 and the blade 140 are on the same vertical axis. The groove width is the same as the blade thickness, and the groove depth meets the cutting requirements of the blade edge. When grooving, the blade edge of the blade 140 can be partially inserted into the embedded groove 150, which ensures that the carton is completely grooved and avoids direct contact between the blade and the second drive roller, while also reducing the generation of burrs on the bottom of the cardboard.

[0023] The auxiliary component 200 is disposed on the surface of the machining disk 130 and is activated when adjusting the tool pitch. Its core function is to replace the meshing transmission between the insert 140 and the tool holder slider 120 in the groove 150, thereby preventing the insert 140 from bearing lateral force.

[0024] The auxiliary component 200 includes a mating plate 215 disposed on the surface of the processing disk 130. The thickness of the mating plate 215 is the same as the width of the embedding groove 150. One end of the mating plate 215 near the embedding groove 150 adopts an arc-shaped design. The curvature of the arc-shaped end matches the curvature of the edge of the embedding groove. This allows the plate to slide smoothly into the groove during adjustment, even if there is a slight deviation in position, by means of the arc-shaped guide, reducing impact and wear. Guide grooves 214 are provided on both sides of the mating plate 215. These guide grooves 214 cooperate with the guide ribs inside the housing 210, which not only enhances the overall bending strength of the mating plate 215, but also cooperates with the internal structure of the housing 210, limiting the sliding of the mating plate 215 to only the vertical direction and preventing displacement.

[0025] The auxiliary component 200 also includes a housing 210 disposed on the surface of the processing plate 130. A mating plate 215 slides in the housing 210. A spring 213 is fixedly connected to the inner wall of the housing 210. The other end of the spring 213 is fixedly connected to the mating plate 215. In its natural state, the spring 213 can push the mating plate 215 downward to extend out of the housing 210. After adjustment, the mating plate 215 can be retracted by compressing the spring 213 with external force.

[0026] A connecting buckle 211 is fixedly connected to the surface of the housing 210, and a connecting head 212 is correspondingly provided on the surface of the mating plate 215. The connecting buckle can hook with the connecting head to lock the position of the mating plate 215 in the non-adjustment state.

[0027] When personnel need to use the mating plate 215 to penetrate into the embedding groove 150 to replace the blade 140 and drive the tool holder slider 120 to adjust the tool distance together with the machining disk 130, the personnel first remove the connecting buckle 211 from the connector 212. At this time, the spring 213 will drive the mating plate 215 to extend downward until the lower end of the mating plate 215 is in contact with the inner wall of the embedding groove 150 of the tool holder slider 120, thus completing the connection. Subsequently, when the machining disk 130 moves, the mating plate 215 can be used to drive the tool holder slider 120 to move together.

[0028] The auxiliary component 200 also includes a groove 221 formed on the surface of the machining disk 130. A slide block 220 is horizontally slidably connected in the groove 221. The side of the slide block 220 closest to the housing 210 is fixedly connected to the housing 210. By sliding the slide block 220 along the groove 221, the lateral position of the auxiliary component 200 on the machining disk 130 can be adjusted to meet different tool distance adjustment requirements.

[0029] Three auxiliary components 200 are provided, all of which are installed on the surface of the machining disk 130 and are respectively located between the two cutting blades 140, ensuring that the tool holder slider 120 can be synchronously adjusted through the nearest auxiliary component 200 no matter what angle the machining disk 130 is rotated to.

[0030] Slotting working principle: According to the slotting requirements of the carton to be processed, the spacing of the blades 140 is adjusted in advance, and the positions of the processing plate 130 and the knife holder slider 120 are locked by bolts; the connecting buckle 211 of the auxiliary component 200 is hooked with the connector 212, so that the mating plate 215 is retracted into the housing 210 to avoid interfering with the slotting; then the equipment is started, and the first drive roller 160 and the second drive roller 110 rotate synchronously in opposite directions. The carton to be processed is placed into the feeding end of the equipment, and the carton is conveyed between the two rollers along with the roller shaft. When the carton passes between the blades 140 and the knife holder slider 120, the cutting edge of the blades 140 cuts into the carton and partially extends into the embedded groove 150, completing the slotting operation. The slotted carton is output from the discharge end.

[0031] When it is necessary to adjust the slot spacing, first loosen the bolts locking the machining disc 130 and the tool holder slider 120. Then, operate the auxiliary component 200 on the station that needs to be moved, and disconnect the connector 212 from the connector buckle 211. At this time, the spring 213 drives the mating plate 215 to extend, so that the arc-shaped end of the mating plate 215 extends downward into the embedded groove 150. Next, activate the equipment's built-in adjustment mechanism (such as a handwheel or electric adjustment device) to move the processing disc 130 laterally along the first drive roller 160. Since the mating plate 215 engages with the embedded groove 150, the movement of the processing disc 130 will cause the tool holder slider 120 to slide synchronously along the second drive roller 110 via the mating plate 215 until the blade 140 spacing reaches the preset specification. After confirming the tool spacing adjustment is in place, manually push the mating plate 215 upwards to compress the spring 213 until the mating plate 215 retracts into the housing 210. Re-engage the connecting buckle 211 with the connecting head 212 to lock the position of the mating plate 215. Then tighten the locking bolts of the processing disc 130 and the tool holder slider 120 to ensure the components are fixed in position. Finally, re-lock the processing disc 130 and the tool holder slider 120 to resume the grooving operation. Throughout the entire process, the cutting blade 140 does not participate in the force transmission and is thoroughly protected.
