Description

Technical Field

[0001] This utility model belongs to the field of material processing technology, and in particular relates to an automatic edge trimming device. Background Technology

[0002] In the processing of roll or sheet materials, edge trimming is an important step to ensure the consistency of product dimensions and the quality of the finished product's appearance.

[0003] The prior art, authorized by CN204802726U, discloses a cutting and rolling machine, which includes a housing. Inside the housing, a feeding device, an edge trimming device, a cutting device, and a rolling device are arranged sequentially. The edge trimming device includes a rotating material pad roller and two edge trimming blades rotating above the material pad roller. The two edge trimming blades are located at both ends of the material pad roller. Below both ends of the material pad roller, an edge guide roller and an edge winding roller are rotatably arranged. The trimmed edge material is guided by the edge guide roller and then collected by the edge winding roller. The formed fabric undergoes edge trimming before packaging, and the trimmed scraps are collected into a roll by the edge guide roller and the edge collecting roller.

[0004] This device primarily uses a circular cutter to cut edge material and guides the edge material into a take-up roller for centralized winding. It suffers from the following core technical defects:

[0005] (1) Edge material is processed by winding, which makes it difficult to remove in time. Furthermore, long strips of edge material are prone to tangling and knotting under high-speed operation, which is not conducive to continuous operation.

[0006] (2) Lacking adsorption function, it is impossible to absorb edge material in time, resulting in limited equipment space and poor operation stability.

[0007] Therefore, there is an urgent need to develop an integrated edge trimming device with automatic cutting, edge material adsorption and conveying, and online crushing capabilities to improve edge material processing efficiency and ensure continuous and stable operation of the production line. Utility Model Content

[0008] In order to solve the problems of the existing technology, this utility model proposes an automatic edge trimming device with automatic cutting and the ability to absorb the trimmed edge material.

[0009] An automatic trimming device, characterized in that it comprises:

[0010] The cutting and positioning module 1 includes: a circular cutter 11, a cutting power unit 12 for driving the circular cutter 11 to rotate, a blade holder assembly 13 for mounting the circular cutter 11 and the cutting power unit 12, and a sliding assembly 14 for moving the blade holder assembly 13;

[0011] The edge material collection and processing module 2 includes: an adsorption and conveying sub-module 21: having an air inlet 22 located near the cutting area, a fan for providing negative pressure suction, and a conveying pipeline 24 connecting the air inlet 22 and the fan;

[0012] The suction control module includes: a speed detection unit for detecting the operating speed, a fan control unit connected to the speed detection unit by signal, and a fan connected to the fan control unit by control, for adjusting the suction intensity of the fan in real time according to the operating speed;

[0013] The suction port 22 and the conveying pipeline 24 are connected to the inlet of the edge material collection and processing module 2, forming a continuous edge material suction and conveying system. By setting up a cutting positioning module, an edge material collection and processing module, and a suction control module, an automated and integrated edge material processing system is formed, which can achieve precise cutting, immediate collection, synchronous conveying, and real-time adaptive suction intensity of edge materials. This improves cutting quality while effectively avoiding edge material scattering and pollution, as well as blockage problems caused by insufficient suction, and is adaptable to various operating conditions.

[0014] Furthermore, a crushing submodule is also provided within the conveying pipeline 24 connecting the air intake 22 and the blower. The crushing submodule includes crushing components and a crushing power unit 25 that drives the crushing components. The crushing power unit 25 is linked to the start / stop operation of the blower. By integrating the crushing submodule into the conveying pipeline, edge material can be crushed synchronously during the suction process, preventing long strips of edge material from becoming entangled or blocked within the pipeline, thus ensuring system operational stability. The linkage control between the crushing power unit and the blower reduces energy consumption and improves system coordination and automation.

[0015] Furthermore, the crushing submodule also includes a screening structure 3. The screening structure 3 is a screen with a preset aperture, located at the output end of the crushing submodule, used to limit the particle size of the edge material after crushing. The screening structure further controls the particle size of the edge material within a safe range, ensuring that the crushed material size meets the requirements of subsequent processing, preventing large-sized edge material from clogging the hose or damaging downstream equipment, and improving the applicability and safety of the device.

[0016] Furthermore, the crushing component is a high-speed rotating impeller with a rotation speed of not less than 3000 rpm; the screening structure 3 is a replaceable screen with an adjustable screen aperture of 10-30 mm. By limiting the impeller rotation speed and screen aperture parameters, efficient crushing and particle size control of edge materials are achieved, ensuring the stability of the crushing effect; the replaceable screen design enhances the equipment's adaptability and ease of maintenance under different material conditions.

[0017] In some embodiments, the tool holder assembly 13 is further provided with a material edge detection sensor, which is connected to the control terminal of the sliding assembly 14 that moves the tool holder assembly 13, for the purpose of realizing automatic calibration of the tool holder assembly 13.

[0018] In some embodiments, the cutting power unit 12 is a servo motor with a rated power of 1.1kW; the circular cutter 11 has a diameter of 80-150mm and a cutting line speed of not less than 150m / min.

[0019] In some embodiments, the blower is a high-pressure blower with a rated wind pressure of not less than 20 kPa; the conveying pipeline 24 is a wear-resistant flexible hose with an inner diameter of 40-60 mm and a length not exceeding 5 m.

[0020] In some embodiments, an environmental control module is also included, comprising an electrostatic elimination unit and / or a temperature control unit disposed near the cutting area. By adding an environmental control module, the risks arising from electrostatic accumulation or heat sensitivity of the material during the cutting process are effectively addressed, further improving the system's adaptability to various materials and preventing quality defects caused by electrostatic adsorption or edge adhesion.

[0021] Furthermore, the static elimination unit is an ion bar structure; the temperature control unit is a resistance or PTC ceramic heating structure with a temperature control range of 20℃-150℃, and is equipped with a PID controller. The use of an ion bar and a PID precision heating device provides high responsiveness and accuracy in static elimination and temperature control, ensuring that the cut material 4 does not warp, melt, or become charged during edge trimming, thus improving product quality consistency and cutting effect stability.

[0022] The beneficial effects of this utility model are as follows: This utility model proposes an automatic edge trimming device, including a cutting and positioning module 1, an edge material collection and processing module 2, and a suction control module. By setting up the cutting and positioning module, the edge material collection and processing module, and the suction control module, and by setting up the circular cutter and its sliding component in the cutting and positioning module, the device achieves the effect of precise cutting and positioning of materials of different widths. The suction port of the adsorption and conveying sub-module is connected to the fan to form a continuous conveying channel, which achieves the effect of efficiently and synchronously collecting edge trimming waste and avoiding edge material scattering. This creates an automatic edge trimming system that integrates cutting, adsorption, crushing, screening, and control, which has the beneficial effects of improving cutting accuracy, synchronously and efficiently collecting edge material, avoiding hose blockage, adapting to changes in operating speed, and ensuring continuous and stable operation of the system. The overall structure is compact and the response is rapid. Attached Figure Description
