Description

Technical Field

[0001] This utility model relates to the technical field of roller cutting devices, and in particular to a roller cutting device for a rewinding machine. Background Technology

[0002] The rewinder roller cutting device, as a key piece of equipment working in conjunction with the rewinder, plays an indispensable role in the entire production process. Its main task is to precisely cut long strips of rollers into shorter ones. These cut short rollers are then conveyed in an orderly manner to the rewinder. When the rewinder slits large rolls of various materials, such as paper and plastic film, the separated material is tightly wound onto these short rollers. This not only greatly improves the uniformity of the material but also provides numerous conveniences for subsequent processing and product transportation, effectively improving overall production efficiency and logistics convenience.

[0003] However, traditional rewinding machine roller cutting devices have many obvious limitations and cannot meet the needs of modern automated mass production. In the design of traditional devices, only the alignment mechanism and the cutting mechanism are provided to the operator. When performing roller cutting operations, the operator needs to manually move the roller and place it into a pre-set fixed position on the cutting device. This process is not only physically demanding but also time-consuming. After placing the roller, the operator must carefully move the cutting blade manually according to the instructions of the alignment mechanism to complete the cutting operation. Because it relies entirely on manual operation, the operator's skill level and working condition have a significant impact on the cutting accuracy, resulting in the cut roller length often failing to fully meet production requirements, easily leading to length deviations, and consequently affecting the quality of subsequent production.

[0004] Furthermore, after the roller cutting is completed, operators still need to manually collect and arrange the cut roller segments. This additional step not only increases the labor intensity of the operators but also further reduces production efficiency. In today's increasingly automated production environment, these drawbacks of traditional rewinding machine roller cutting devices are becoming increasingly prominent, severely restricting the production scale and economic benefits of enterprises. Therefore, optimizing and upgrading the rewinding machine roller cutting device has become an urgent task to achieve more efficient, precise, and automated production operations. Utility Model Content

[0005] This invention overcomes the shortcomings of existing technologies and provides a roller cutting device for a rewinding machine. The inner inclined surface of the storage rack utilizes the gravity of the rollers to allow them to roll naturally, eliminating the need for additional power, reducing costs and energy consumption, and improving the convenience and efficiency of material feeding. The lifting and pushing plate has a reasonable width, ensuring accurate feeding of single strands and avoiding chaotic cutting. In case of blockage, the anti-blocking cylinder drives the anti-blocking push plate to push away the blocked rollers, ensuring material flow and reducing downtime. The pressing, cutting, and end-stopping components of the cutting assembly work together. The pressing roller prevents the rollers from jumping up, the rotating clamping block ensures stable cutting, and the circular blade ensures cutting accuracy. The swing receiving roller shaft of the unloading assembly moves flexibly, supporting the rollers during cutting and allowing them to fall into the receiving trough after completion, realizing automated unloading. The cooperation of all components enables automatic roller picking and cutting, reducing labor intensity and improving efficiency and accuracy.

[0006] To solve the above-mentioned technical problems, the utility model is implemented through the following technical solution: A rewinding machine roller cutting device includes a storage rack body, an inner inclined receiving surface is provided inside the storage rack body, a cutting component and a feeding component are provided on one side of the storage rack body, the feeding component includes a basic receiving roller shaft and an oscillating receiving roller shaft, the oscillating receiving roller shaft can be close to or away from the basic receiving roller shaft.

After the rollers roll out from the inner inclined surface of the receiving device, one roller falls onto the lifting and pushing plate each time. When the lifting and pushing plate rises, it pushes the rollers between the base receiving roller shaft and the swing receiving roller shaft in a combined state. Then, the cutting component cuts the rollers. After the cutting is completed, the moving receiving roller shaft moves away from the base receiving roller shaft, and the rollers fall from between the base receiving roller shaft and the swing receiving roller shaft to the receiving trough.

When the lifting pusher plate rises, the lower side of its upper end surface docks with the higher side of the discharge docking slope. The width of the lifting pusher plate is greater than the diameter of one roller but less than the sum of the diameters of two rollers. After the rollers roll down the inner inclined plane, only one roller can land on the lifting push plate. After the lifting push plate is raised, the roller slides down from the lifting push plate between the base receiving roller and the swing receiving roller.

[0008] Furthermore, the storage rack is equipped with an anti-blocking component, which includes an anti-blocking cylinder connected to an anti-blocking push plate. The output direction of the anti-blocking cylinder is opposite to the installation direction of the feeding assembly. An anti-blocking guide plate is also provided above the anti-blocking cylinder.

[0009] Furthermore, the feeding assembly includes a feeding base, which is composed of a base receiving roller shaft and base side plates connected to its two ends. The lower end of the base side plates is rotatably connected to a feeding swing component. The feeding swing component includes a swing shaft and a swing receiving roller shaft arranged in parallel. Both ends of the swing shaft and the swing receiving roller shaft are connected to a swing arm. When the swing shaft rotates, it drives the swing arm to swing, thereby driving the swing receiving roller shaft to move closer to or away from the base receiving roller shaft.

[0010] Furthermore, one end of the foundation receiving roller is connected to a drive motor.

[0011] Furthermore, a swing arm drive component is provided on the side of the base side plate, and the swing arm drive component includes a swing arm drive cylinder. The swing arm drive cylinder is connected to the swing block via a fisheye connector, and the other end of the swing block is connected to the swing shaft.

[0012] Furthermore, the cutting assembly includes an adjusting rod, on which a pressing component and a cutting component are provided, and at both ends of the adjusting rod are end abutment components; The cutting component is used to cut the roller into segments, the pressing component is used to hold the upper end of the roller against the roller during the cutting process to prevent the roller from jumping up, and the end abutment component is used to hold both ends against the roller during the cutting process.

[0013] Furthermore, the pressing component includes a pressing slide, which is slidably connected to the adjusting rod. The pressing slide is provided with screws that abut against the adjusting rod to fix the position of the pressing slide on the adjusting rod. The pressing slide is connected to the pressing cylinder and the first lifting seat; the first lifting seat is slidably connected to the lifting roller seat, and the output end of the pressing cylinder is connected to the lifting roller seat; the lifting roller seat is rotatably connected to the pressing roller.

[0014] Furthermore, the cutting component includes a cutting slide, which is slidably connected to the adjusting rod. The cutting slide is provided with screws that abut against the adjusting rod to fix the position of the cutting slide on the adjusting rod. The cutting slide connects the cutting lifting cylinder and the second lifting seat. The second lifting seat is slidably connected to the cutting lifting seat. The cutting lifting seat is connected to the circular blade drive motor, and the circular blade drive motor is connected to the circular blade.

[0015] Furthermore, the end abutment component includes an end base, the end base is connected to an end clamping cylinder, the output end of the end clamping cylinder is connected to a clamping rotary seat, and the clamping rotary seat is rotatably connected to a rotating clamping block.

[0016] Compared with existing technologies, the advantages of this utility model are: 1. The ingenious design of the inner inclined surface of the storage rack allows the rollers to roll naturally using their own weight, eliminating the need for additional power equipment to move the rollers. This reduces equipment costs and energy consumption while improving the convenience and efficiency of feeding. The width of the lifting and pushing plate is reasonably designed, being greater than the diameter of one roller but less than the sum of the diameters of two rollers. This ensures that only one roller falls onto it at a time, achieving precise single-roller feeding and avoiding the cutting chaos caused by multiple rollers entering the cutting area simultaneously, thus guaranteeing the orderly progress of the cutting operation.

[0017] 2. When roller blockage occurs, the anti-blockage cylinder can drive the anti-blockage push plate to move, promptly pushing away the blocked roller and allowing the accumulated roller to move again, ensuring smooth material flow, reducing equipment downtime caused by blockage, and improving production efficiency.

[0018] 3. The pressing component, cutting component, and end abutment component in the cutting assembly work together to provide strong support for the cutting operation. The pressing roller of the pressing component abuts against the upper end of the roller to prevent the roller from jumping up during cutting; the rotating clamping block of the end abutment component clamps both ends of the roller and can rotate with it, ensuring the stability of the roller cutting process; the circular blade of the cutting component can accurately cut the roller into segments, ensuring cutting accuracy.

[0019] 4. The swing receiving roller of the feeding assembly can be flexibly moved closer to or further away from the base receiving roller via the swing arm drive component. During cutting, the two are in contact to provide support for the roller; after cutting, the swing receiving roller moves away from the base receiving roller, allowing the roller to fall smoothly into the receiving trough, thus realizing the automation and orderliness of the feeding process.

[0020] Through the effective cooperation of various components, the automatic material handling and cutting function of the roller is realized, reducing the labor intensity of operators and improving the efficiency and accuracy of roller cutting. Attached Figure Description

Detailed Implementation

[0023] The preferred embodiments of the utility model are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the utility model.

[0024] like Figures 1 to 8As shown, a rewinding machine roller cutting device includes a storage rack 1. The storage rack 1 has an inner inclined surface 101 for receiving. The roller to be cut is placed on the inner inclined surface 101. The inner inclined surface 101 can use the roller's own weight to make the roller roll down naturally, preparing it for subsequent cutting operations. A cutting assembly 3 and a feeding assembly 4 are provided on one side of the storage rack 1. The feeding assembly 4 includes a basic receiving roller 4012 and a swing receiving roller 4023. The swing receiving roller 4023 can be close to or away from the basic receiving roller 4012. A receiving trough 403 is provided below the basic receiving roller 4012 and the swing receiving roller 4023 to receive the rollers after cutting and to serve as a temporary storage. The receiving trough 403 is also set with an inclined surface. After the rollers cut into segments fall into the receiving trough 403, they slide down the inclined surface of the receiving trough 403 into the next device.

[0025] The lifting and pushing plate 4042 is located at the lower end of the receiving inner inclined surface 101. After the roller rolls out of the receiving inner inclined surface 101, one roller falls onto the lifting and pushing plate 4042 each time. When the lifting and pushing plate 4042 rises, it pushes the roller between the base receiving roller shaft 4012 and the swing receiving roller shaft 4023 in the combined state. Then the cutting component 3 cuts the roller. After the cutting is completed, the swing receiving roller shaft 4023 moves away from the base receiving roller shaft 4012, and the roller falls from between the base receiving roller shaft 4012 and the swing receiving roller shaft 4023 to the receiving trough 403.

[0026] A pushing component 404 is provided on the side of the basic receiving roller 4012 away from the swing receiving roller 4023. The pushing component 404 includes a lifting pushing plate 4042. A discharge docking slope 102 is provided on the side of the storage rack 1. The upper end of the discharge docking slope 102 is above the basic receiving roller 4012. The lifting pushing plate 4042 is located between the inner slope 101 and the discharge docking slope 102. The upper end of the lifting pushing plate 4042 is a slope. When the lifting pushing plate 4042 descends, the higher side of its upper end is lower than the inner slope 101. When the lifting push plate 4042 rises, the lower side of its upper end face aligns with the higher side of the discharge docking slope 102. The width of the lifting push plate 4042 is greater than the diameter of one roller but less than the sum of the diameters of two rollers. After the roller rolls down from the inner slope 101, only one roller can land on the lifting push plate 4042. After the lifting push plate 4042 rises, the roller slides off the lifting push plate 4042 between the base receiving roller shaft 4012 and the swing receiving roller shaft 4023, preparing for the cutting operation.

[0027] Once the roller is pushed between the base receiving roller 4012 and the oscillating receiving roller 4023, the cutting assembly 3 begins to function, precisely cutting the roller. After the cutting is complete, the oscillating receiving roller 4023 moves away from the base receiving roller 4012, at which point the roller falls from between the two into the receiving trough 403, completing a full cutting and unloading process.

[0028] The storage rack 1 is equipped with an anti-blocking component 2, which includes an anti-blocking cylinder 201 connected to an anti-blocking push plate 202. The output direction of the anti-blocking cylinder 201 is opposite to the installation direction of the feeding assembly 4. When a blockage occurs, the anti-blocking cylinder 201 drives the anti-blocking push plate 202 to move, pushing away the blocked rollers and allowing the accumulated rollers to move again, providing space for the rollers to move and ensuring smooth material flow. In addition, an anti-blocking guide ramp 203 is provided above the anti-blocking cylinder 201, which can guide the rollers to roll down a predetermined path, further reducing the possibility of blockage.

[0029] The feeding assembly 4 includes a feeding base 401, which is composed of a base receiving roller 4012 and base side plates 4011 connected to its two ends. The lower end of the base side plate 4011 is rotatably connected to a feeding swing component 402. The feeding swing component 402 includes a swing shaft 4022 and a swing receiving roller 4023 arranged in parallel. Both ends of the swing shaft 4022 and the swing receiving roller 4023 are connected to a swing arm 4021. When the swing shaft 4022 rotates, it drives the swing arm 4021 to swing, thereby driving the swing receiving roller 4023 to move closer to or away from the base receiving roller 4012.

[0030] One end of the base receiving roller 4012 is connected to the drive motor 406. Therefore, when the roller is between the base receiving roller 4012 and the swing receiving roller 4023, the rotation of the base receiving roller 4012 can drive the roller to rotate. At this time, the circular blade 3046 of the cutting assembly 3 descends and contacts the roller to cut it. Since the roller is constantly rotating, the circular blade 3046 can cut the roller along the circumference of the roller.

[0031] A swing arm drive component 405 is provided on the side of the base side plate 4011. The swing arm drive component 405 includes a swing arm drive cylinder 4051. The swing arm drive cylinder 4051 is connected to a swing block 4052 via a fisheye connector. The other end of the swing block 4052 is connected to a swing shaft 4022. When the swing arm drive cylinder 4051 pushes the end of the swing block 4052 to swing, the end of the swing block 4052 connected to the swing shaft 4022 rotates accordingly, thereby causing the swing shaft 4022 to rotate, thus causing the swing arm 4021 to move away from the base side plate 4011. One end of the swing shaft 4022 swings, thereby enabling the swing receiving roller 4023 to move away from or close to the base receiving roller 4012. When the swing receiving roller 4023 is in contact with the base receiving roller 4012, the space between them serves to support the roller and provides bottom support force for the roller during the cutting process of the roller by the circular blade 3046. After the roller is cut, the swing receiving roller 4023 moves away from the base receiving roller 4012, and a separation occurs between them. The roller then falls from the space between them to the receiving trough 403.

[0032] The cutting assembly 3 includes an adjusting rod 301, on which a pressing component 302 and a cutting component 304 are provided, and at both ends of the adjusting rod 301 are end abutment components 303. The cutting component 304 is used to cut the roller into segments, the pressing component 302 is used to hold the upper end of the roller during the cutting process so that the roller does not jump up, and the end abutment component 303 is used to hold both ends of the roller during the cutting process.

[0033] The pressing component 302 includes a pressing slide 3021, which is slidably connected to the adjusting rod 301. The pressing slide 3021 is provided with screws to abut against the adjusting rod 301 to fix the position of the pressing slide 3021 on the adjusting rod 301. The pressure slide 3021 connects the pressure cylinder 3022 and the first lifting seat 3023; the first lifting seat 3023 is slidably connected to the lifting roller seat 3024, and the output end of the pressure cylinder 3022 is connected to the lifting roller seat 3024; the lifting roller seat 3024 is rotatably connected to the pressure roller 3025. During cutting, the pressure cylinder 3022 drives the lifting roller seat 3024 to descend, causing the pressure roller 3025 to abut against the upper end of the roller, preventing the roller from jumping up during the cutting process and ensuring the accuracy and stability of the cutting.

[0034] The cutting component 304 includes a cutting slide 3041, which is slidably connected to the adjusting rod 301. The cutting slide 3041 is provided with a screw to abut against the adjusting rod 301 to fix the position of the cutting slide 3041 on the adjusting rod 301. The cutting slide 3041 connects the cutting lifting cylinder 3042 and the second lifting seat 3043. The second lifting seat 3043 is slidably connected to the cutting lifting seat 3044. The cutting lifting seat 3044 is connected to the circular knife drive motor 3045. The circular knife drive motor 3045 is connected to the circular blade 3046.

[0035] The end abutment component 303 includes an end base 3031, which is connected to an end clamping cylinder 3032. The output end of the end clamping cylinder 3032 is connected to a clamping rotary seat 3034, which is rotatably connected to a rotating clamping block 3033. Therefore, even though the rotating clamping block 3033 clamps both ends of the roller, the rotating clamping block 3033 can also rotate with the roller, thus ensuring the smooth operation of roller cutting.

[0036] The operating process of the rewinding machine roller cutting device is as follows: First, the roller to be cut is placed on the receiving inner inclined surface 101 inside the storage rack 1, and the roller naturally rolls down under its own gravity. The anti-blocking guide inclined plate 203 in the anti-blocking component 2 guides the roller to roll down along a predetermined path. If a blockage occurs, the anti-blocking cylinder 201 drives the anti-blocking push plate 202 to move, pushing away the blocked roller and ensuring smooth material flow.

[0037] After the rollers roll out from the receiving inner inclined surface 101, one roller falls onto the lifting push plate 4042 located at the lower end of the receiving inner inclined surface 101. When the lifting push plate 4042 descends, the higher side of its upper end face aligns with the lower side of the inner inclined surface 101, facilitating the rollers to roll off; when it rises, the lower side of its upper end face aligns with the higher side of the discharge docking inclined surface 102, pushing the rollers between the combined base receiving roller shaft 4012 and the swing receiving roller shaft 4023.

[0038] The drive motor 406 at one end of the base receiving roller 4012 starts, driving the base receiving roller 4012 to rotate, which in turn drives the roller between the base receiving roller 4012 and the swing receiving roller 4023 to rotate. The pressing component 302 in the cutting assembly 3 is activated, and the pressing cylinder 3022 drives the lifting roller seat 3024 to descend, so that the pressing roller 3025 abuts against the upper end of the roller to prevent the roller from jumping up during the cutting process. The end clamping cylinder 3032 of the end abutting component 303 drives the clamping rotating seat 3034 to move, so that the rotating clamping block 3033 clamps both ends of the roller, and the rotating clamping block 3033 can rotate with the roller to ensure that the roller cutting is carried out smoothly.

[0039] Next, the cutting lifting cylinder 3042 of the cutting component 304 drives the cutting lifting seat 3044 to descend, and the circular blade drive motor 3045 drives the circular blade 3046 to descend and contact the rotating roller, cutting the roller along the circumference.

[0040] After cutting, the swing arm drive cylinder 4051 of the swing arm drive component 405 pushes the end of the swing block 4052 to swing, causing the swing shaft 4022 to rotate, driving the swing arm 4021 to swing, thereby moving the swing receiving roller shaft 4023 away from the base receiving roller shaft 4012. At this time, the roller falls from between the base receiving roller shaft 4012 and the swing receiving roller shaft 4023 into the receiving trough 403. The receiving trough 403 is set with an inclined surface, and the roller cut into segments slides down the inclined surface into the next device, completing a complete cutting and unloading process.

[0041] The inner inclined surface 101 inside the material storage rack 1 of the cutting device of this utility model is ingeniously designed. It can make the roller roll down naturally by its own weight, without the need for additional power equipment to move the roller, thus reducing equipment costs and energy consumption. At the same time, it improves the convenience and efficiency of feeding. The width of the lifting and pushing plate 4042 is reasonably designed, which is greater than the diameter of one roller but less than the sum of the diameters of two rollers, ensuring that only one roller falls on it at a time. This achieves precise single-roller feeding and avoids the cutting chaos caused by multiple rollers entering the cutting area at the same time, thus ensuring the orderly progress of the cutting operation.

[0042] When roller blockage occurs, the anti-blockage cylinder 201 can drive the anti-blockage push plate 202 to move, promptly pushing away the blocked roller and allowing the accumulated roller to move again, ensuring smooth material flow, reducing equipment downtime caused by blockage, and improving production efficiency.

[0043] The pressing component 302, cutting component 304, and end abutment component 303 in the cutting assembly 3 work together to provide strong support for the cutting operation. The pressing roller 3025 of the pressing component 302 abuts against the upper end of the roller to prevent the roller from jumping up during cutting; the rotating clamping block 3033 of the end abutment component 303 clamps both ends of the roller and can rotate with it, ensuring the stability of the roller cutting process; the circular blade 3046 of the cutting component 304 can accurately cut the roller into segments, ensuring cutting accuracy.

[0044] The swing receiving roller 4023 of the feeding assembly 4 can be flexibly moved closer to or further away from the base receiving roller 4012 via the swing arm drive component 405. During cutting, the two are in contact to provide support for the roller; after cutting, the swing receiving roller 4023 moves away from the base receiving roller 4012, allowing the roller to fall smoothly into the receiving trough 403, thus realizing the automation and orderliness of the feeding process.

[0045] Through the effective cooperation of various components, the automatic material handling and cutting function of the roller is realized, reducing the labor intensity of operators and improving the efficiency and accuracy of roller cutting.

[0046] Finally, it should be noted that the above are merely preferred embodiments of the utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the utility model should be included within the protection scope of the utility model.
