Description

Technical Field

[0001] This utility model relates to the field of canvas cutting technology, and in particular to a canvas production and cutting device with a waste material recycling function. Background Technology

[0002] Canvas is a type of fabric woven from canvas yarn, possessing excellent abrasion resistance, waterproof properties, and breathability. It is commonly used in the production of outdoor products such as tents, backpacks, and hats. A search revealed Chinese utility model patent application number 202222594493.9, which discloses a cutting device for canvas bag production. This device is primarily used for cutting canvas during canvas bag production. Upon completion of cutting, a drive motor is activated, moving the canvas to a waste separation structure where a fan is activated. The fan quickly separates the waste material from the cut material, causing it to fall into a collection box.

[0003] Regarding the existing technology, the inventors also discovered a potential problem: since the main components of canvas are cotton and linen, a large amount of lint is generated during the cutting process. If a blower is used to separate the waste, this lint may be blown into the surrounding environment, which is detrimental to maintaining a clean production environment and ensuring work efficiency.

[0004] Therefore, how to ensure effective separation of waste while minimizing environmental pollution is an urgent problem to be solved. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a canvas production cutting device with waste material recycling function to solve the above problems.

[0006] To achieve the above objectives, this utility model provides a canvas production cutting device with waste material recycling function, including a support frame, an unwinding unit and a winding unit disposed at both ends of the support frame, a belt conveyor disposed between the unwinding unit and the winding unit, a cutting unit mounted on the belt conveyor, and a separation unit disposed between the winding unit and the belt conveyor.

[0007] The separation unit includes a rotating roller rotatably mounted on the bracket, a push block slidably disposed on the side of the rotating roller for pushing the canvas cutting material downward, and a spring connected between the push block and the rotating roller.

[0008] Preferably, the bracket is equipped with a motor that drives the rotating roller to rotate.

[0009] Preferably, the pushing block is provided with an attraction groove, and the inside of the rotating roller is provided with a negative pressure chamber, which is connected to the attraction groove through a connecting pipe.

[0010] Preferably, the bracket is fixedly mounted with a filter box, the upper end of the filter box is connected to the negative pressure chamber through a connecting pipe, and the lower end of the filter box is connected to a negative pressure fan.

[0011] Preferably, a receiving box is provided below the separation unit.

[0012] Preferably, the belt conveyor is fixedly mounted with a slide rail, and the cutting unit is slidably mounted inside the slide rail.

[0013] Preferably, pressure rollers are installed at both ends of the bracket near the inner sides of the unwinding unit and the winding unit.

[0014] Compared with the prior art, this utility model has the following advantages: This utility model replaces the traditional method of using a fan to blow off the cutting material by pushing the cutting material and the canvas residue when the rotating roller rotates. This can effectively prevent cotton lint from flying away. In addition, through the design of the negative pressure chamber and the suction groove, the cotton lint on the canvas surface can be sucked away, which can effectively improve the processing environment.

Detailed Implementation

[0021] The following is in conjunction with the appendix Figure 1-4 The specific embodiments of this utility model will be described in further detail.

[0022] Depend on Figure 1-4This invention discloses a canvas production cutting device with a waste material recycling function, comprising a support 10, an unwinding unit 20 and a winding unit 30 disposed at both ends of the support 10, a belt conveyor 40 disposed between the unwinding unit 20 and the winding unit 30, a cutting unit 50 mounted on the belt conveyor 40, and a separation unit 60 disposed between the winding unit 30 and the belt conveyor 40. The cutting unit 50 is a laser cutter. In use, the canvas is unwound through the unwinding unit 20, and the unwound canvas is cut by the cutting unit 50. The cut material is separated by the separation unit 60, and the waste material after cutting the canvas is wound up by the winding unit 30.

[0023] In the existing technology, the separation device for canvas cutting material is mainly a fan. During processing, the canvas cutting material is cut and then blown off by the fan. Since the main raw material of canvas is cotton and linen, this method can easily cause cotton fibers to fly into the environment.

[0024] To solve the above problems, the present invention mainly improves the separation unit 60.

[0025] In this embodiment, the separation unit 60 includes a rotating roller 61 rotatably mounted on the bracket 10, a pushing block 62 slidably disposed on the side of the rotating roller 61 for pushing the canvas cutting material downwards, and a spring 63 connected between the pushing block 62 and the rotating roller 61. The bracket 10 is equipped with a motor 67 that drives the rotating roller 61 to rotate. During operation, the external power supply of the motor 67 is turned on, causing the rotating roller 61 to rotate continuously. During the rotation, the lower surface of the rotating roller 61 and the upper surface of the canvas remain in close contact. It can be understood that when the canvas surface is intact, the pushing block 62 will automatically retract into the rotating roller 61 and compress the spring 63 when it approaches the canvas surface. When the pushing block 62 reaches the part of the cutting material, the rotating roller 61 will automatically push the cutting material downwards, causing the cutting material to peel off from the canvas. Compared with the method of blowing with a fan in the prior art, this method can effectively prevent cotton fibers from flying away and reduce environmental pollution.

[0026] Furthermore, in order to collect the cotton lint generated during cutting, the push block 62 is provided with an attraction groove 65, and the inside of the rotating roller 61 is provided with a negative pressure chamber 64. The negative pressure chamber 64 is connected to the attraction groove 65 through a connecting pipe 66. When the rotating roller 61 rotates, it drives the push block 62 to rotate. The negative pressure chamber 64 generates suction on the surface of the canvas through the attraction groove 65, thereby sucking away the cotton lint generated during cutting. It is understood that the suction should be controlled to be less than the weight of the cutting material.

[0027] Specifically, a filter box 68 is fixedly installed on the bracket 10. The filter box 68 is equipped with a filter screen 682. The upper end of the filter box 68 is connected to the negative pressure chamber 64 through a connecting pipe 681, and the lower end of the filter box 68 is connected to a negative pressure fan 69.

[0028] Below the separating unit 60 is a receiving box 70 for receiving the cut material.

[0029] In some embodiments, the belt conveyor 40 is fixedly mounted with a slide rail 80, and the cutting unit 50 is slidably mounted in the slide rail 80 to facilitate adjustment of the position of the cutting unit 50.

[0030] In some embodiments, pressure rollers 90 are installed at both ends of the support 10 near the inner sides of the unwinding unit 20 and the winding unit 30 to press the canvas.

[0031] The purpose of this invention is to provide a canvas production cutting device with a waste material recycling function. By improving the design of the separation unit and using structures such as the negative pressure chamber, it effectively prevents cotton lint from scattering and reduces environmental pollution.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 the technical features of the units therein. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
