Description

Technical Field

[0001] This utility model relates to the field of three-coordinate cutting machine equipment technology, and in particular to a dust collection device for a garment cutting machine. Background Technology

[0002] Three-coordinate vibrating knife cutting machines are a type of efficient and precise cutting equipment commonly used in modern garment industrial production. They are widely used for cutting various materials such as leather, fabric, and foam. During the operation of the vibrating knife cutting machine, a certain amount of dust and debris is generated. At the same time, this high-frequency vibration also makes the dust and debris generated during the cutting process more likely to fly around. Therefore, modern vibrating knife cutting machines need to be equipped with special dust collection equipment to suck up the dust and debris generated during the cutting process and prevent them from flying around and affecting the working environment and machine performance. However, the dust collection devices of existing garment cutting machines generally have the problems of small suction ports and insufficient suction power.

[0003] For example, Chinese utility model patent CN221988952U discloses a dust collection device for a garment cutting machine. Although the solution can cover the dust generated during cutting by adding a dust cover, and the dust generated during the cutting process is sucked into the dust collection box through the dust suction pipe when the exhaust fan is started, so as to reduce the pollution of the working environment, the air guide groove and the central hole on the lower side of the dust cover are very small. This may lead to insufficient suction power of the dust collection device and insufficient dust collection space.

[0004] Based on this, a dust collection device for a garment cutting machine is proposed to solve the above problems. Utility Model Content

[0005] To address the technical problem of the narrow suction port of the dust collection device in a garment cutting machine, this utility model provides a dust collection device for a garment cutting machine.

[0006] This utility model is achieved using the following technical solution: a dust collection device for a garment cutting machine, including a cutting machine frame, a base on the cutting machine frame, a limiting frustum fixedly connected to one side of the base, a plurality of first suction grooves arranged in a circumferential array on the lower side of the limiting frustum, a circular groove on the upper side of the limiting frustum, a sealing box rotatably connected to the inner side of the circular groove, a plurality of second suction grooves arranged in a circumferential array on the lower side of the sealing box, the second suction grooves cooperating with the first suction grooves, a sealing box rotation mechanism for connecting or blocking the first and second suction grooves on the upper side of the base, and a dust collection mechanism on the outer side of the limiting frustum.

[0007] As a further improvement to the above solution, the sealing box rotation mechanism includes a mounting plate fixedly connected to one side of the base, a connecting cylinder rotatably connected to the lower side of the mounting plate, the lower side of the connecting cylinder communicating with the upper side of the sealing box, and a vibrating knife cutting mechanism for rotating the sealing box is provided on the inner side of the connecting cylinder.

[0008] As a further improvement to the above solution, the vibrating knife cutting mechanism includes multiple linear slide grooves opened inside the connecting cylinder. The multiple linear slide grooves are arranged in a circumferential array. The upper end of each linear slide groove is connected to a spiral slide groove opened inside the connecting cylinder. A pointer rod is slidably connected to the inner side of each linear slide groove. The ends of the multiple pointer rods that are close to each other are fixedly connected to a vibrating knife assembly. A vibrating knife lifting mechanism is provided on the upper side of the vibrating knife assembly.

[0009] As a further improvement to the above solution, the vibrating knife lifting mechanism includes a cylinder mounted on the upper side of the mounting plate, the output end of the cylinder extending downward and fixedly connected to a connecting rod, and the lower end of the connecting rod being fixedly connected to the upper side of the vibrating knife assembly.

[0010] As a further improvement to the above solution, the dust collection mechanism includes a flow guide groove hole opened on one side of the sealing box, a dust suction connecting pipe connected to one side of the limiting frustum, the lower port of the dust suction connecting pipe being configured to cooperate with the flow guide groove hole, and a dust suction mechanism being provided on the upper side of the base.

[0011] As a further improvement to the above solution, the vacuuming mechanism includes a vacuum cleaner assembly fixedly connected to the upper side of the base, and one side of the vacuum cleaner assembly is connected to the upper port of the vacuuming connecting pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. When the vibrating knife assembly lowers to cut, the pointer rod on one side pushes the spiral slide to rotate at a certain angle, which in turn pushes the sealing box to rotate, so that the first suction groove and the second suction groove on the lower side are aligned and connected, thereby expanding the area of ​​the dust suction port on the lower side of the limiting truncated cone and improving the dust suction capacity.

[0014] 2. When the sealing box is reversed, the vibrating knife assembly rises, and the first and second suction grooves on the lower side block each other, which can prevent the dust in the vacuum cleaner connecting pipe and the vacuum cleaner assembly from flowing back, and improve the sealing performance.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] Example:

[0025] Please combine Figures 1-6 The dust collection device of a garment cutting machine in this embodiment includes a cutting machine frame 1. It should be noted that the existing technology of three-coordinate cutting machine is very mature. The cutting machine frame 1 mainly has the functions of forward and backward and left and right movement to meet the position requirements during cutting.

[0026] As shown in Figure 5, the machine frame 1 of the cutting machine is equipped with a base 3, which is a movable slide table. In this embodiment, it can be driven by a linear module, which has the advantage of high precision.

[0027] Please combine Figure 4 As shown, a limiting frustum 6 is fixedly connected to one side of the base 3. Multiple suction grooves 9 arranged in a circular array are provided on the lower side of the limiting frustum 6. A circular groove is provided on the upper side of the limiting frustum 6. A sealing box 11 is rotatably connected to the inner side of the circular groove. In this embodiment, the sealing box 11 has a circular structure and a hollow structure inside.

[0028] Please combine Figure 5As shown, the lower side of the sealed box 11 is provided with multiple second suction grooves 14 arranged in a circular array, and the second suction grooves 14 are arranged in cooperation with the first suction groove 9.

[0029] When the sealing box 11 rotates clockwise, the second suction groove 14 rotates along with it until it completely overlaps with the first suction groove 9 to form a passage, at which point vacuuming can be performed;

[0030] When the sealing box 11 is reversed, the second suction groove 14 and the first suction groove 9 are offset from each other and blocked, thus sealing the box. At this time, vacuuming is not possible.

[0031] The upper side of the base 3 is provided with a sealing box rotation mechanism that allows the first suction groove 9 and the second suction groove 14 to communicate with or block each other, and a dust collection mechanism is provided on the outer side of the limiting round platform 6.

[0032] Please combine Figure 4 As shown, the sealing box rotation mechanism includes a mounting plate 10 fixedly connected to one side of the base 3, and a connecting cylinder 8 rotatably connected to the lower side of the mounting plate 10. The connecting cylinder 8 is a cylindrical hollow structure.

[0033] The lower side of the connecting cylinder 8 is connected to the upper side of the sealing box 11, and the inner side of the connecting cylinder 8 is provided with a vibrating knife cutting mechanism that makes the sealing box 11 rotate.

[0034] Please combine Figure 6 As shown, in this embodiment, the vibrating knife cutting mechanism includes two linear slide grooves 17 opened inside the connecting cylinder 8. The two linear slide grooves 17 are arranged in a circumferential array. The upper end of each linear slide groove 17 is connected to a spiral slide groove 16 opened inside the connecting cylinder 8. A pointer rod 13 is slidably connected to the inner side of each linear slide groove 17. The ends of the two pointer rods 13 that are close to each other are fixedly connected to the vibrating knife assembly 7. A vibrating knife lifting mechanism is provided on the upper side of the vibrating knife assembly 7.

[0035] Please combine Figure 4 and Figure 6 As shown, the vibratory knife lifting mechanism includes a cylinder 5 mounted on the upper side of the mounting plate 10. The output end of the cylinder 5 extends downward and is fixedly connected to a connecting rod 12. The lower end of the connecting rod 12 is fixedly connected to the upper side of the vibratory knife assembly 7.

[0036] When the pointer rod 13 moves within the linear slide 17, the vibrating knife assembly 7 only changes its height in the vertical direction, and the sealing box 11 does not rotate.

[0037] When the pointer rod 13 moves and slides in the spiral groove 16, the vibrating knife assembly 7 changes its height in the vertical direction while pushing the sealing box 11 to rotate, so as to connect or block the first suction groove 9 and the second suction groove 14.

[0038] Please combine Figure 6As shown, the dust collection mechanism includes a guide slot 15 opened on one side of the sealing box 11, a dust suction connecting pipe 4 connected to one side of the limiting frustum 6, the lower end of the dust suction connecting pipe 4 and the guide slot 15 are configured to cooperate with each other, and a dust suction mechanism is provided on the upper side of the base 3.

[0039] When the sealing box 11 rotates and the first suction groove 9 connects with the second suction groove 14, the guide groove hole 15 on the sealing box 11 is connected to the lower port of the dust collection connecting pipe 4.

[0040] When the guide slot hole 15 is misaligned with the lower port of the suction pipe 4, the suction pipe 4 can be blocked.

[0041] Please combine Figure 1 As shown, the vacuuming mechanism includes a vacuum cleaner assembly 2 fixedly connected to the upper side of the base 3, and one side of the vacuum cleaner assembly 2 is connected to the upper port of the vacuuming connecting pipe 4.

[0042] The implementation principle of the dust collection device of a garment cutting machine in this embodiment is as follows: the cutting machine frame 1 controls the movement position of the three-coordinate cutting machine, enabling the vibrating knife assembly 7 to move forward, backward, left, and right. At the same time, the cylinder 5 pushes the connecting rod 12 down, causing the vibrating knife assembly 17 to slide downward along the inner side of the connecting cylinder 8. At this time, the pointer rod 13 on the side of the vibrating knife assembly 17 moves downward. When passing through the spiral slide 16 track section, it drives the connecting cylinder 8 and the sealing box 11 to rotate, thereby making the first suction groove 9 on the limiting round 6 and the second suction groove 14 under the sealing box 11 overlap and connect. At this time, the dust collector assembly 2 can absorb and collect the dust generated during the vibrating knife cutting through the dust collection connecting pipe 4 and the guide slot hole 15. When passing through the straight slide 17 track section, the connecting cylinder 8 does not rotate, but only changes in vertical height. Conversely, when the vibrating knife assembly 17 rises upward under the drive of the cylinder 5, the sealing box 11 reverses, and the first suction groove 9 and the second suction groove 14 block each other to seal, preventing dust backflow.

[0043] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
