Description

Technical Field

[0001] This utility model belongs to the technical field of flatbed irregular shape cutting machine, and relates to a hot air smoothing mechanism for preventing curling in flatbed irregular shape cutting machine. Background Technology

[0002] Flatbed cutting machines are widely used in industries such as cardboard, plastics, and leather. They can precisely cut flat materials and enable automated production. A flatbed cutting machine consists of a cutting platform, a sliding beam, and a cutting head. The sliding beam is mounted horizontally above the cutting platform and can slide back and forth along the left and right edges of the platform. The cutting head is mounted on the sliding beam and can slide along it, allowing the cutting head to groove at any point within the cutting platform.

[0003] Chinese utility model patent CN203956996U discloses a partitioned flatbed cutting machine, including a cutting platform, a machine head, and a sliding beam. The sliding beam is horizontally installed above the cutting platform, with its left and right ends respectively installed on the left and right edges of the cutting platform, allowing the sliding beam to slide along the edges of the cutting platform. The machine head is installed on the sliding beam, allowing the machine head to slide along the sliding beam. The cutting platform is divided into at least two areas, each with an exhaust pipe underneath. Each exhaust pipe has a valve and a connector, with the lower end of each exhaust pipe connected to the connector. The connector has an exhaust fan connecting pipe, which communicates with each exhaust pipe. This technical solution divides the cutting platform into multiple areas. During operation, the exhaust fan only extracts air from the flat material in the area where the machine head is located, effectively creating an exhaust fan under each area. This results in a more even and enhanced adsorption force on the flat material. However, this technical solution may cause problems such as bending and warping of the cut material, affecting subsequent product quality and production efficiency. Utility Model Content

[0004] To address the issues of bending and warping that may occur in the cut material, affecting subsequent product quality and production efficiency, this utility model proposes an anti-curling hot air smoothing mechanism for a flat irregular-shaped cutting machine. This mechanism effectively solves the problems of bending and warping that may occur in the cut material, thus affecting subsequent product quality and production efficiency in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A hot air smoothing mechanism for preventing curling in a flat irregular-shaped cutting machine includes a flat irregular-shaped cutting machine and a cutting mechanism disposed on the flat irregular-shaped cutting machine. Two connecting plates are symmetrically arranged at the front and rear ends of the cutting mechanism. A hot air mechanism and a smoothing mechanism are disposed on the opposite sides of the two connecting plates, located on the right side of the cutting mechanism. The hot air mechanism is located between the cutting mechanism and the smoothing mechanism.

[0006] Furthermore, the hot air mechanism includes a hot air box disposed on opposite sides of two connecting plates, an air outlet being provided through the lower side of the hot air box, multiple blowers being disposed inside the hot air box, multiple heating elements being disposed inside the hot air box, the heating elements being located between the blowers and the air outlet of the hot air box, and multiple air inlets being provided through the right side of the hot air box, the air inlets corresponding to the positions of the blowers.

[0007] Furthermore, a dustproof net is provided on the inner side of the hot air box, and the dustproof net is located on one side of the air inlet.

[0008] Furthermore, the smoothing mechanism includes two cylinders symmetrically arranged on opposite sides of two connecting plates. A push plate is provided at the output end of the cylinder, a mounting plate is provided on the side of the push plate, and a coupling is provided on the lower side of the mounting plate. A pressure roller is rotatably connected between the two couplings.

[0009] Furthermore, the pressure roller includes a drive shaft, with both ends of the drive shaft rotatably connected to two couplings. An inner shaft is provided on the outer side of the drive shaft, and an outer shaft is provided on the outer side of the inner shaft. The drive shaft, the inner shaft, and the outer shaft are all connected and driven by a riveting structure.

[0010] Furthermore, the outer side of the outer shaft is covered with an elastic layer.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The present invention softens the material after cutting through the hot air mechanism, thereby improving the smoothing effect and smoothing efficiency of the subsequent material. The smoothing mechanism presses down and smooths the material, improving the flatness of the material and preventing the material from warping or bulging. The multi-layer structure of the pressure rollers makes the pressure rollers lightweight and quick to load and unload, improving the work efficiency of the workers when installing the pressure rollers.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0015] like Figures 1 to 6 As shown, a hot air smoothing mechanism for preventing curling in a flat irregular-shaped cutting machine includes a flat irregular-shaped cutting machine 1 and a cutting mechanism 101 mounted on the flat irregular-shaped cutting machine 1. The aforementioned flat irregular-shaped cutting machine 1 and cutting mechanism 101 are both existing technologies, and their internal structures and working principles are well known to those skilled in the art, and will not be described in detail here. Two connecting plates 4 are symmetrically mounted on the front and rear ends of the cutting mechanism 101 by bolts. A hot air mechanism 2 and a smoothing mechanism 3 are provided on the opposite sides of the two connecting plates 4, located on the right side of the cutting mechanism 101. The hot air mechanism 2 and the smoothing mechanism 3 can move synchronously with the cutting mechanism 101. The hot air mechanism 2 is located between the cutting mechanism 101 and the smoothing mechanism 3.

[0016] In use, the cutting mechanism 101 on the flatbed irregular shape cutting machine 1 can cut the material on the flatbed irregular shape cutting machine 1. After the cutting is completed, the hot air mechanism 2 on one side of the cutting mechanism 101 can heat the cut material with hot air to soften it. Then, the smoothing mechanism 3 on one side of the hot air mechanism 2 can press down and smooth the softened material to prevent the cut material from bending and curling, thereby improving the production quality of the material, reducing rework in the production of the material, and improving the working efficiency of the flatbed cutting machine.

[0017] In this embodiment, the hot air mechanism 2 includes a hot air box 201 bolted to the opposite sides of two connecting plates 4. An air outlet is provided through the lower side of the hot air box 201. Multiple blowers 202 are bolted inside the hot air box 201, and multiple heating elements 203 are bolted inside the hot air box 201. The heating elements 203 are connected to an external power source and are located between the blowers 202 and the air outlet of the hot air box 201. Multiple air inlets are provided through the right side of the hot air box 201. The air inlet 204 corresponds to the position of the blower 202. The working principle of the blower 202 and the heating element 203 is the prior art, which is well known to those skilled in the art and will not be described in detail here. In addition, in this technical solution, the model and specification of the blower 202 is XGB-7.5KW(810) / 380V, and the flow rate is 530. In actual production and use, the staff can adjust the model and quantity of the blower 202 and the heating element 203 according to the actual production needs.

[0018] In use, the blower 202 can draw in outside air through the air outlet and spray it towards the heating plate 203. Then, under the action of the heating plate 203, the heating plate 203 can heat the air sprayed by the blower 202. The heated air can be discharged along the air outlet below the hot air box 201, and heat and soften the material below the air outlet, so as to facilitate subsequent pressing and smoothing, and ensure the cutting production quality of the material.

[0019] In this embodiment, the smoothing mechanism 3 includes two cylinders 301 symmetrically mounted on opposite sides of two connecting plates 4 by bolts. A push plate 302 is bolted to the output end of each cylinder 301. A mounting plate 303 is bolted to the lower side of the push plate 302. A coupling 304 is bolted to the lower side of the mounting plate 303. The coupling 304 is an aluminum alloy double diaphragm coupling with dimensions of 68*Φ25*74mm. A pressure roller 5 is rotatably connected between the two couplings 304 via bearings. The two cylinders 301 can achieve synchronous pushing and operation under the drive of the same air pump. The dimensions of each cylinder 301 are SDA32*100mm. The dimensions of the coupling 304 and cylinders 301 can be adjusted and selected according to actual production needs and working environment.

[0020] During use, the two cylinders 301 can push the pressure roller 5 downwards synchronously, so that the pressure roller 5 comes into contact with the material on the flat irregular cutting machine 1. Under the action of the hot air mechanism 2, the material after cutting has softened. The pressure roller 5 can move with the cutting structure and press down on the softened material to flatten it, preventing the material after cutting from bulging and curling up, ensuring the flatness of the material after cutting, and improving the production quality of the material.

[0021] Example 2 differs from Example 1 in that: like Figure 5 As shown, in this embodiment, a dustproof net 6 is installed on the inner side of the hot air box 201 by bolts. The dustproof net 6 is located on one side of the air inlet 204. In use, the dustproof net 6 can prevent external dust and debris from entering the hot air box 201 through the air inlet 204, ensuring the cleanliness of the inside of the hot air box 201 and ensuring the reliability of the blower 202 and the heating element 203 in use.

[0022] Example 3 differs from Example 1 in that: like Figure 6 As shown, the pressure roller 5 includes a drive shaft 501, with both ends of the drive shaft 501 rotatably connected to two couplings 304. An inner shaft 502 is sleeved on the outer side of the drive shaft 501, and an outer shaft 503 is sleeved on the outer side of the inner shaft 502. The drive shaft 501, inner shaft 502, and outer shaft 503 are all connected and driven by a riveting structure. In use, the multi-layer design of the pressure roller 5 reduces the overall weight of the pressure roller 5, making it lighter and improving the work efficiency of the workers when installing the pressure roller 5. At the same time, the riveting structure used between the drive shaft 501, inner shaft 502, and outer shaft 503 effectively improves the connection strength and transmission efficiency between the drive shaft 501, inner shaft 502, and outer shaft 503, ensuring the reliability of the pressure roller 5 during rotation.

[0023] In this embodiment, the outer shaft 503 is covered with an elastic layer 504. The material of the elastic layer 504 can be high-temperature rubber or other elastic materials. The operator can adjust it according to the actual production needs, which ensures the reliability of the pressure roller 5 during use. The setting of the elastic layer 504 can form a buffer between the outer shaft 503 and the material, preventing the material from being damaged due to friction, and further improving the production efficiency and production quality of the flat irregular shape cutting machine 1.

[0024] Example 4 differs from Example 1 in that: The above technical solution can also add an electrostatic dust removal mechanism to the connecting plate 4 by bolts. The electrostatic dust removal mechanism is located on the side of the smoothing mechanism 3 away from the hot air mechanism 2. The electrostatic dust removal mechanism includes an electrostatic dust removal box and an electrode plate. The electrode plate can adsorb dust and debris on the surface of the material, further improving the cleanliness of the material surface and thus improving the production quality of the material.

[0025] Although the present invention has been described in detail with reference to the foregoing 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
