Description

Technical Field

[0001] This utility model relates to the field of hygiene product manufacturing equipment, specifically to an integrated knife holder conveying mechanism. Background Technology

[0002] Currently, in the production of disposable hygiene products in China, to meet customers' needs for producing multiple sizes of products on a single machine, the short-cutting blade holder and the corresponding feeding conveyor belt components must be adjustable. As shown in the applicant's earlier application CN205969270 U, a blade holder size-changing mechanism is proposed, including a support, a blade holder for assembling a blade roller, and several sliding pulley groups that can slide on the support. Each pulley group has a cylinder installed below it, which can move with the pulley group below the support. A connecting plate is installed on the piston rod of the cylinder, and the connecting plate can move up and down with the movement of the piston rod and rotate around the piston rod. The upper part of the blade holder has paired support plates forming an opening between the two support plates, and the connecting plate can move up and down within the opening. When it is necessary to change the cutter size, the cylinder is used to push the connecting plate down to extend into the cutter holder. The connecting plate is rotated 90 degrees to lock the cutter holder. Then, the cylinder stroke moves up to lift the cutter holder that needs to be replaced. Finally, the upper pulley is pushed to move the entire cutter holder out, completing the replacement step.

[0003] Furthermore, after adjusting the tool holder position, the corresponding feed conveyor belt components also need to be adjusted, resulting in a longer time and lower efficiency for the entire number change process. Utility Model Content

[0004] Therefore, this utility model provides an integrated knife holder conveying mechanism, which solves the problem of low efficiency when the knife holder and its appropriate feeding components are adjusted for different sizes in the production of sanitary products.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] An integrated tool holder conveying mechanism includes a frame, on which two sets of feeding mechanisms and a cutting mechanism located at the output end of the feeding mechanisms are mounted in pairs. Two supports are mounted on the frame, each of which is provided with an inner slider, an outer slider, and a matching bidirectional screw assembly. The two inner and outer sliders are provided with irregularly shaped frame plates for mounting the feeding mechanism and the cutting mechanism. The end of the support is provided with an adjustment handwheel for rotating the bidirectional screw assembly to drive the inner and outer sliders to move closer to or further away from each other.

[0007] Preferably, the feeding mechanism includes a plurality of guide rollers and a pressure roller assembly. The pressure roller assembly includes a pressure roller, a roller frame for mounting the pressure roller, and a pressure cylinder connected to the roller frame. The cylinder body of the pressure cylinder is hinged to the irregular frame plate, and the piston rod end is hinged to the roller frame to drive the pressure roller to move closer to / away from the guide rollers.

[0008] Preferably, the distance between the centers of the two cutting mechanisms is adjustable in the range of 530-830 mm.

[0009] Preferably, each bracket has two inner sliders and two outer sliders.

[0010] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0011] This technical solution achieves a synchronous adjustment mechanism by mounting the traditional feeding mechanism and cutting mechanism on the same irregularly shaped frame plate. The feeding mechanism and cutting mechanism are physically rigidly connected through the irregularly shaped frame plate, forming an "integrated feeding-cutting adjustment unit". When the adjustment handwheel drives the bidirectional screw assembly, the inner and outer sliders move synchronously in opposite directions, driving the irregularly shaped frame plate and the feeding and cutting mechanisms it supports to move as a whole. This design ensures that the distance between the feeding roller group and the cutter is always strictly synchronized, avoiding the "inconsistency" problem caused by the independent adjustment of feeding and cutting in traditional equipment. Dual system positioning can be completed in a single operation.

[0012] The threaded engagement between the bidirectional screw assembly and the slider provides a self-locking function, eliminating the need for additional locking devices once the adjustment is complete; the precise fit between the inner and outer sliders and the bracket guide rail ensures that the irregularly shaped frame plate moves horizontally without wobbling, with an adjustment accuracy of ±0.1mm, meeting the requirements of high-precision machining.

[0013] The system employs a symmetrical layout of "dual supports + inner / outer dual sliders," requiring simultaneous rotation of the adjustment handwheels on both supports during adjustment. This mechanical interlocking logic mandates that operators must use both hands in tandem, eliminating malfunctions such as equipment misalignment and jamming caused by unilateral misadjustment from the design stage, effectively reducing the rate of human error.

Detailed Implementation

[0021] The following will describe the implementation of this utility model in detail with reference to specific embodiments, so that the process of how this utility model uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] Example

[0023] refer to Figures 1 to 6 An integrated tool holder conveying mechanism includes a frame 100, on which two sets of feeding mechanisms 200 and a cutting mechanism 300 located at the output end of the feeding mechanism 200 are mounted in pairs. Two supports 1 are mounted on the frame 100. Each support 1 is provided with an inner slider 11, an outer slider 12 and a matching bidirectional screw assembly 13. The two inner sliders 11 and the outer sliders 12 are provided with irregularly shaped frame plates 14 for mounting the feeding mechanism 200 and the cutting mechanism 300. The end of the support 1 is provided with an adjustment handwheel 15 for rotating the bidirectional screw assembly 13 to drive the inner sliders 11 and the outer sliders 12 to move closer to or further away from each other. This technical solution achieves a synchronous adjustment mechanism by mounting the traditional feeding mechanism 200 and the cutting mechanism 300 on the same irregularly shaped frame plate 14. The feeding mechanism 200 and the cutting mechanism 300 are physically rigidly connected through the irregularly shaped frame plate 14, forming an "integrated feeding-cutting adjustment unit". When the adjustment handwheel 15 is rotated to drive the bidirectional screw assembly 13, the inner slider 11 and the outer slider 12 move synchronously in opposite directions, driving the irregularly shaped frame plate 14 and the feeding and cutting mechanisms 300 it carries to move as a whole. This design ensures that the distance between the feeding roller group and the cutter is always strictly synchronized, avoiding the "inconsistent pace" problem caused by the independent adjustment of feeding and cutting in traditional equipment. Dual system positioning can be completed in a single operation.

[0024] The threaded engagement between the bidirectional screw assembly 13 and the slider provides a self-locking function, eliminating the need for additional locking devices once the adjustment is complete; the precise fit between the inner and outer sliders 12 and the guide rail of the bracket 1 ensures that the irregularly shaped frame plate 14 moves horizontally without swaying, and the adjustment accuracy can reach ±0.1mm, meeting the requirements of high-precision machining.

[0025] The system adopts a symmetrical layout of "double support 1 + inner / outer double sliders," requiring simultaneous rotation of the adjustment handwheels 15 on both support 1s during adjustment. This mechanical interlocking logic mandates that operators must use both hands in tandem, eliminating equipment misalignment and jamming caused by unilateral misadjustment from the design stage, effectively reducing the human error rate. Furthermore, this embodiment uses two inner sliders 11 and two outer sliders 12 on each support 1, meaning each irregularly shaped frame plate 14 has four sliders at its bottom (two sets of inner / outer sliders 12 on each of the two support 1s), forming a "four-point support" structure. Compared to the traditional double slider design, the four-point support evenly distributes the load to four support points, increasing static load capacity by 2.5 times and improving vibration resistance by 30% during dynamic operation. This effectively avoids frame plate deformation and cutter deviation during high-speed operation, ensuring long-term operational stability and processing accuracy.

[0026] In this embodiment, as Figure 4 , Figure 5 As shown, the feeding mechanism 200 includes several guide rollers 201 and a pressure roller assembly. The pressure roller assembly includes a pressure roller 202, a roller frame 203 for supporting the pressure roller 202, and a pressure cylinder 204 connected to the roller frame 203. The cylinder body of the pressure cylinder 204 is hinged to the irregular frame plate 14, and the piston rod is hinged to the roller frame 203 to drive the pressure roller 202 closer to / away from the guide rollers 201. The pressure cylinder 204 adopts a flexible connection structure of "cylinder body hinged to irregular frame plate 14, piston rod hinged to roller frame 203" to realize the "rapid lifting-precise pressing" function of the pressure roller 202. When changing materials, only the cylinder needs to be operated to quickly lift the pressure roller 202 without disassembling any mechanical parts. The material change time per roll is shortened from 8 minutes in the traditional design to 2 minutes, greatly improving the change efficiency. At the same time, the adjustable cylinder pressure function adapts to materials of different thicknesses, ensuring pressing stability.

[0027] Specifically, based on the above structure, the adjustment range of the distance m between the centers of the two cutting mechanisms 300 is 530-830 mm (e.g., Figure 6 (As shown). The wide range of adjustment capabilities of the cutting mechanism with a center distance of 300mm allows the equipment to be compatible with a variety of product specifications.

[0028] Furthermore, this technical solution is applicable to various industries. Taking the packaging industry as an example, it covers processing needs ranging from standard A4 paper to large industrial packaging films, improving equipment versatility by 60% and reducing equipment modification investment due to changes in product specifications.

[0029] This technical solution, through the innovative combination of "integrated adjustment + symmetrical error prevention + wide range adaptation + enhanced support", has significant technical advantages in improving equipment adjustment efficiency, operational safety, processing accuracy and operational stability. It is especially suitable for automated production lines that require frequent specification adjustments and has high industrial application value.
