Description

Technical Field

[0001] The present application relates to the technical field of non-woven fabric processing, and specifically to a laser cutting device for non-woven fabrics. Background Art

[0002] In the process of using non-woven fabrics to manufacture packaging bags, it is necessary to first design patterns and various graphics, and through laser cutting, precise processing of non-woven fabric raw materials can be achieved.

[0003] After the existing laser cutting device cuts patterns on the raw materials, the conveyor belt will transport the whole forward. However, the cut fabric of the pattern part will separate from the remaining raw materials at the end of the conveyor belt, and some of the pattern fabrics will get stuck at the bottom of the conveyor belt against the conveyor belt, causing the laser cutting transmission to freeze, thus delaying the normal operation of subsequent cutting.

[0004] Therefore, it is necessary to provide a laser cutting device for non-woven fabrics to solve the above problems.

[0005] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of the present application, and therefore, it may include information that does not constitute the prior art. Summary of the Invention

[0006] Based on the above problems existing in the prior art, the problem to be solved by the present application is: to provide a laser cutting device for non-woven fabrics, which solves the problem that the laser cutting transmission freezes due to the pattern fabrics getting stuck at the bottom against the conveyor belt.

[0007] The technical solution adopted by the present application to solve its technical problems is: a laser cutting device for non-woven fabrics, including a machine body, a conveyor belt, and a guiding component; the conveyor belt is arranged inside the machine body through a gear shaft and operates through a driving mechanism; two support frames are fixedly installed on one side of the machine body; the conveyor belt is located between the two support frames, the bottom of the guiding component is slidably connected to the support frames, and one side of the guiding component is located at one end of the conveyor belt;

[0008] Wherein: the guiding component includes an inclined plate and two support plates, the bottom of the inclined plate is fixedly connected to the two support plates, and the two support plates are arranged oppositely; a sliding key is fixedly installed at the bottom of the support plate; the plane where the inclined surface of the inclined plate is located is tangent to the end of the conveyor belt, the side of the inclined plate close to the conveyor belt does not contact the conveyor belt, and the gap is smaller than the fabric thickness; a chute is provided at the top of the support frame, and the sliding key and the corresponding chute are a matching structure;

[0009] Thus, after the fabric on the conveyor belt is laser cut, the driving mechanism controls the conveyor belt to move forward, and the fabric of the pattern part and the remaining raw materials are removed from the conveyor belt. The inclined plate scrapes the working surface of the conveyor belt to prevent the fabric of the pattern part and the remaining raw materials from entering the machine body along with the conveyor belt after separation.

[0010] Furthermore, an auxiliary component is fixedly installed at one end of the machine body on the support frame. The auxiliary component includes a collection box body. One side of the collection box body is fixedly connected to the machine body, and the collection box body is located below the support frame. A storage cavity is provided at the top of the collection box body, and one side of the storage cavity communicates with the outside of the collection box body. The storage cavity is located directly below the inclined plate. Thus, the fabric slides down from the inclined plate into the storage cavity for collection.

[0011] Furthermore, two shaft seats are fixedly installed at the top of the collection box body. The storage cavity is located between the two shaft seats, and the shaft seats are located on the side away from the machine body. A rotating shaft is installed on the shaft seat through a bearing. A roller is fixedly installed on the outside of the rotating shaft between the two shaft seats. A waste material winding component is provided at one end of the collection box body away from the machine body. Thus, after the cut fabric leaves the conveyor belt, it passes under the roller and is wound by the waste material winding component. During this process, the pattern fabric separates from the remaining fabric due to gravity, and the pattern fabric falls into the storage cavity.

[0012] Furthermore, a storage drawer is installed at the storage cavity through a sliding connection. The storage drawer collects the pattern fabric, facilitating the rapid transfer of the pattern fabric at the storage cavity by the staff later and avoiding the explosion of the storage cavity.

[0013] Furthermore, two L-shaped frames are fixedly installed at one end of the machine body on the support frame. The conveyor belt is located between the two L-shaped frames. Wind cavities are fixedly installed at the tops of the two L-shaped frames. The wind cavities are located above the inclined plate and directly above the storage cavity. Air outlets are evenly opened at the bottom of the wind cavity close to the collection box body. An air inlet is opened on one side of the wind cavity. The air inlet and the air outlets are communicated through the inner cavity of the wind cavity. The air inlet is connected to an external air pump through a pipeline. Thus, the air pump inputs cold air into the wind cavity through the air inlet and then discharges it from the air outlets. The cold air blows downward to cool the cut fabric. At the same time, a downward thrust is provided to the pattern fabric to avoid the situation that the connection end points between the pattern fabric and the remaining fabric are not easily separated quickly.

[0014] The beneficial effects of this application are as follows: A laser cutting device for non-woven fabrics provided by this application realizes [content missing in the original] through [content missing in the original], thus [content missing in the original].

[0030] As Figures 1-3 shown, this application provides a laser cutting device for non-woven fabrics, which is applied to non-woven fabric processing. It includes a machine body 1, a conveyor belt 2, and a guiding component 3. The conveyor belt 2 is arranged inside the machine body 1 through a gear shaft and operates through a driving mechanism. Two support frames 11 are fixedly installed on one side of the machine body 1. The conveyor belt 2 is located between the two support frames 11. The bottom of the guiding component 3 is slidably connected to the support frame 11, and one side of the guiding component 3 is located at one end of the conveyor belt 2.

[0031] Among them: Referring to Figure 2 、 Figure 3 , the guiding component 3 includes an inclined plate 31 and two support plates 32. The bottom of the inclined plate 31 is fixedly connected to the two support plates 32, and the two support plates 32 are arranged oppositely. A sliding key 321 is fixedly installed at the bottom of the support plate 32. The plane where the inclined surface of the inclined plate 31 is located is tangent to the end of the conveyor belt 2. The side of the inclined plate 31 close to the conveyor belt 2 does not contact the conveyor belt 2, and the gap is smaller than the fabric thickness. A chute 111 is provided at the top of the support frame 11, and the sliding key 321 and the corresponding chute 111 are a matching structure.

[0032] Thus, after the fabric on the conveyor belt 2 is laser cut, the driving mechanism controls the conveyor belt 2 to move forward, and the patterned part of the fabric and the remaining raw materials are removed from the conveyor belt 2. The inclined plate 31 scrapes the working surface of the conveyor belt 2 to prevent the patterned part of the fabric and the remaining raw materials from entering the machine body 1 along with the conveyor belt 2 after being separated.

[0033] Embodiment 2: In the above Embodiment 1, for the separate collection of the cut fabric and the remaining fabric, manual separation and collection are still required. Therefore, the laser cutting device in Embodiment 1 is optimized, and the specific content is as follows:

[0034] Referring to Figure 4 、 Figure 5, at one end of the support frame 11, the machine body 1 is fixedly installed with an auxiliary component.

[0035] Among them: Refer to Figure 4 , Figure 5 , two shaft seats 412 are fixedly installed at the top of the collection box body 41. The storage cavity 411 is located between the two shaft seats 412, and the shaft seats 412 are located on the side far from the machine body 1; a rotating shaft 421 is installed on the shaft seat 412 through a bearing, and a roller 422 is fixedly installed on the outside of the rotating shaft 421 between the two shaft seats 412; a waste material winding component is arranged at one end of the collection box body 41 far from the machine body 1; thus, after the cut fabric leaves the conveyor belt 2, it passes under the roller 422 and is wound by the waste material winding component; during this movement, the pattern fabric is separated from the remaining fabric due to gravity, and the pattern fabric falls into the storage cavity 411.

[0036] Refer to Figure 4 , a storage drawer 43 is installed at the storage cavity 411 through a sliding connection. The storage drawer 43 collects the pattern fabric, which is convenient for the later staff to quickly transfer the pattern fabric at the storage cavity 411 and avoid the storage cavity 411 from bursting.

[0037] Embodiment Three: In order to ensure the integrity of the separation action of the cut fabric and the remaining fabric, on the basis of the above Embodiment Two, the laser cutting device in Embodiment Two is optimized, and the specific content is as follows:

The wind cavity body 51 is located above the inclined plate 31 and directly above the storage cavity 411; air outlets 52 are evenly opened at the bottom of the wind cavity body 51 close to the collection box body 41, and an air inlet 511 is opened on one side of the wind cavity body 51. The air inlet 511 and the air outlets 52 are communicated through the inner cavity of the wind cavity body 51; a pipeline is connected to the air inlet 511 through an external air pump; thus, the air pump inputs cold air into the wind cavity body 51 through the air inlet 511 and then discharges it from the air outlets 52; the cold air blows downward to cool the cut fabric; at the same time, a downward thrust is provided to the pattern fabric, avoiding the situation that the pattern fabric and the remaining fabric have connection endpoints and are not easily separated quickly, and at the same time, it can accelerate the movement of the pattern fabric at the guiding component 3 and avoid the fabric from accumulating at the guiding component.

[0039] It should be noted that the parts not involved in the present utility model are the same as or can be implemented by the prior art; the driving mechanism in the present utility model can use the existing motor to drive the pulley to realize the operation of the conveyor belt, and the surplus material winding assembly in the present utility model can use the existing fabric winding machine to collect the cut fabric.
