Description

Technical Field

[0001] The invention relates to the technical field of material conveying, in particular to a conveying mechanism with a protective mechanism for processing school bags. Background Art

[0002] Backpack processing is a complex process involving multiple links. The fabric needs to be cut during the processing. According to the size of the design drawing, the fabric is reasonably arranged on the cutting table. In this step, we should try to save fabric and reduce waste. Use cutting tools to cut the fabric into the shape of various parts of the backpack, for example, cut out the backpack body, sides, pockets, shoulder straps and other parts.

[0003] During the fabric conveying process, the fabric needs to be cut. At this time, there is no object to support the bottom of the fabric. Fabric is a soft material. Without support, it is easy to move during the cutting process. For example, when cutting with laser cutting or mechanical tools, the fabric may shake due to its own flexibility and the force generated by the cutting tool, which will cause the cutting edge to be uneven and unable to meet the precise size requirements. If you are making backpack parts that require high-precision cutting, such as pockets or decorative patches with complex shapes, this imprecise cutting may make it impossible to accurately splice the parts, affecting the overall quality of the backpack. Unsupported fabric is prone to deformation during cutting. Due to the pressure exerted by the cutting tool, the fabric may be stretched, wrinkled, etc. For some backpack fabrics that have high requirements for shape and flatness, such as leather or fabrics with special textures, deformation may damage their appearance and performance, making subsequent processing difficult.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The corresponding part of the cloth conveyed by the conveyor belt reaches the lower surface of the lower assembly plate. The piston rod of the first electric push rod drives the mounting sleeve and the upper mounting plate to descend. After the pressure ring contacts the cloth, the special cutting knife extends through the lower assembly plate to contact the cloth. The conveyor belt is supported by the upper U-shaped assembly frame to ensure that the cloth has enough objects to support it when it is cut. When the upper structure presses and cuts the cloth, the cloth can remain stable during the cutting process. Because the cloth is a relatively soft material, it is easy to move during the cutting process. Precise pressure control can fix the cloth tightly on the lower support structure, making the cutting path more accurate, reducing the jagged or irregular shape of the cutting edge, and improving the quality of the product. The U-shaped assembly frame supports the cloth and can provide a flat cutting platform. For some wrinkled or uneven cloth, the lower support structure can lift the cloth so that it is in a relatively flat state during cutting, thereby protecting the cloth during the cutting process.

[0017] 2. According to the width of the cloth, by twisting the adjusting screw, the rotation of the adjusting screw drives the side telescopic frame to move in the top assembly plate, and when the side telescopic frame moves in the top assembly plate, it drives the structure on the side telescopic frame to move, and the cloth pressing wheel arranged on the side telescopic frame reaches the corresponding position on both sides of the cloth, and the pressure exerted by the cloth pressing wheel on the cloth is buffered by the deformation of the reset spring. The pressure fixing structure can be adjusted according to the width of the cloth to tightly clamp both sides of the cloth, effectively limiting the movement of the cloth in the horizontal direction. When both sides of the cloth are stably fixed, the cutting machine can focus more on the processing operation of the middle part of the cloth without worrying about the change of the overall position of the cloth, thereby improving the effect of cloth cutting.

An upper mounting plate 9 is fixedly mounted on the bottom of the mounting sleeve 7. The upper mounting plate 9 and the structure below the upper mounting plate 9 can be replaced to achieve the replacement of special cutting knives 16 of different shapes to ensure the cutting of parts of different shapes. A mounting ring 10 is fixedly mounted on the outer wall of the upper mounting plate 9. A mounting column 11 is fixedly mounted inside the mounting ring 10. The mounting column 11 is fixedly mounted on the mounting ring 10. Through the cooperation of the mounting column 11 and the lifting ring 12, the lower mounting plate 13 and the upper mounting plate 9 are assisted to approach each other. After the lower mounting plate 13 approaches the upper mounting plate 9, the special cutting knife 16 at the bottom of the upper mounting plate 9 is exposed to achieve The special cutting knife 16 contacts the cloth, and a lifting ring 12 is movably sleeved outside the mounting column 11. A lower assembly plate 13 is arranged between the lifting rings 12 for fixed connection, and the lower assembly plate 13 is located directly below the upper mounting plate 9. The lower assembly plate 13 and the upper mounting plate 9 cooperate with each other to realize the cutting of the cloth. A buffer spring 14 sleeved outside the mounting column 11 is arranged between the lifting ring 12 and the mounting ring 10. The buffer spring 14 is used for the rebound after the upper mounting plate 9 and the lower assembly plate 13 are close to each other, and assists the upper mounting plate 9 and the lower assembly plate 13 to move away from each other. A pressure ring 15 is fixedly installed at the bottom of the lifting ring 12, and a special cutting knife 16 is fixedly installed at the bottom of the upper mounting plate 9.

An upper U-shaped assembly frame 20 is arranged above the lower U-shaped assembly frame 19, and a V-shaped elastic plate 21 is fixedly installed on the bottom of the upper U-shaped assembly frame 20. The bottom end of the V-shaped elastic plate 21 is rotatably connected with a buffer wheel 22, and the buffer wheel 22 is supported at a corresponding position on the upper surface of the lower U-shaped assembly frame 19. The foundation is raised by installing the second electric push rod 18 through the inner mounting frame 17, and the piston rod of the second electric push rod 18 pushes the lower U-shaped assembly frame 19 to rise and fall.The lower U-shaped assembly frame 19 and the upper U-shaped assembly frame 20 form a structure that rises and falls. The lower U-shaped assembly frame 19 and the upper U-shaped assembly frame 20 cooperate with the descending special cutting knife 16. The special cutting knife 16 cuts and presses the cloth from above. The upper U-shaped assembly frame 20 supports the conveyor belt 3 and the cloth above the conveyor belt 3 from below to ensure the fixed effect of the cloth being supported and prevent the cloth from shifting during the cutting process. When the piston rod of the second electric push rod 18 moves upward, it drives the lower U-shaped assembly frame 19 and the upper U-shaped assembly frame 20 to rise, and the structure formed by the lower U-shaped assembly frame 19 and the upper U-shaped assembly frame 20 is deformed. The connection position of the upper U-shaped assembly frame 20 and the lower U-shaped assembly frame 19 is a wrapped design. At the same time, when the lower U-shaped assembly frame 19 and the upper U-shaped assembly frame 20 approach each other, the V-shaped elastic plate 21 will be deformed, which is used to reset the structure formed by the lower U-shaped assembly frame 19 and the upper U-shaped assembly frame 20.

[0035] The upper U-shaped assembly frame 20 is arranged at a corresponding position at the bottom of the lower assembly plate 13, and the lower assembly plate 13 and the buffer wheel 22 are respectively arranged above the conveyor belt 3 and inside the conveyor belt 3, ensuring that the upper U-shaped assembly frame 20 and the lower assembly plate 13 are located on both sides of the cloth to ensure the fixing effect of the cloth.

[0036] The thickness of the pressure ring 15 is the same as the distance between the lower assembly plate 13 and the upper mounting plate 9. When the pressure ring 15 is pressurized and the lower assembly plate 13 approaches the upper mounting plate 9, the special cutting knife 16 under the upper mounting plate 9 can be exposed through the groove on the lower assembly plate 13, so that the special cutting knife 16 can be exposed and cut.

[0037] The upper U-shaped assembly frame 20 and the lower U-shaped assembly frame 19 are symmetrically arranged in an upper and lower manner. The V-shaped elastic plate 21 is an elastic member. The V-shaped elastic plate 21 has an elastic design, which can ensure that the upper U-shaped assembly frame 20 and the lower U-shaped assembly frame 19 are reset after being close to each other.

[0038] A side telescopic frame 23 is movably installed in the top assembly plate 2, and the side telescopic frame 23 can move laterally on the top assembly plate 2. A U-shaped buckle 24 is fixedly installed on the top assembly plate 2, and a positioning screw 25 is threadedly connected to the U-shaped buckle 24. The positioning screw 25 is rotatably connected to the side telescopic frame 23, and the rotation of the positioning screw 25 drives the side telescopic frame 23 to move laterally on the top assembly plate 2. The lateral movement of the side telescopic frame 23 changes the position of the cloth pressing wheel 31 to ensure that the cloth pressing wheel 31 can apply pressure to the edge of the cloth. An assembly top frame 26 is fixedly installed on the upper surface of the side telescopic frame 23, and the top of the assembly top frame 26 A third electric push rod 27 is fixedly installed on the inside, a lifting sleeve 28 is fixedly installed on the bottom end of the piston rod of the third electric push rod 27, an inner telescopic plate 29 is movably installed in the lifting sleeve 28, a plurality of return springs 30 are arranged on the top end of the inner telescopic plate 29, the top end of the return spring 30 is fixedly installed on the top end of the lifting sleeve 28, a plurality of cloth pressing wheels 31 are arranged on the bottom end of the inner telescopic plate 29, the piston rod of the third electric push rod 27 drives the lifting sleeve 28 to rise and fall, and when the lifting sleeve 28 is raised and lowered, the cloth pressing wheel 31 is driven to rise and fall, and the cloth pressing wheel 31 contacts with the edge of the cloth, thereby fixing the cloth, and at the same time does not affect the conveying of the cloth on the conveyor belt 3.

[0039] Both top assembly plates 2 are provided with side telescopic frames 23 and structures installed on the side telescopic frames 23, and the two sets of side telescopic frames 23 and structures installed on the side telescopic frames 23 are arranged symmetrically on the left and right, and the two sets of cloth pressing wheels 31 correspond to the two sides of the cloth to ensure the stability of the cloth during the comfort process.

[0040] A rectangular mounting sleeve 32 is fixedly installed on both sides of the inner side of the assembly base frame 1 near the unloading end, a lifting strip 33 is movably installed in the rectangular mounting sleeve 32, a telescopic slot 3201 is opened on the rectangular mounting sleeve 32, a semicircular card slot 3301 is opened on the lifting strip 33, and a wind cooling device 34 is fixedly connected to the bottom ends of the two lifting strips 33, a U-shaped frame 35 is fixedly installed on the rectangular mounting sleeve 32, a telescopic card strip 36 is movably installed in the telescopic slot 3201, and the telescopic card strip 36 is located in the semicircular card slot 3301, and the U-shaped frame An adjusting screw 37 is threadedly connected on 35, and the adjusting screw 37 is rotatably connected to the telescopic clamping strip 36. The lifting strip 33 is lifted and lowered in the rectangular mounting sleeve 32, thereby driving the air cooling device 34 to lift and lower. The air cooling device 34 is arranged at a corresponding position above the fabric to ensure that the fabric is cooled. During the lifting and lowering process of the lifting strip 33, it is necessary to push the telescopic clamping strip 36 to be extended and retracted by twisting the adjusting screw 37. The adjusting screw 37 is located in the semicircular clamping groove 3301 to fix the lifting and lowering of the lifting strip 33 in the rectangular mounting sleeve 32.

[0041] The width of the semicircular slot 3301 is the same as the width of the telescopic clip 36 . The telescopic clip 36 is located in the semicircular slot 3301 to fix the lifting and lowering of the lifting bar 33 .

[0042] The air cooling device 34 is arranged on the upper mounting plate 9 near the unloading side, and the air cooling device 34 cools down the cloth so that the cloth will not be burned by being cut by the heated special cutting knife 16 .

[0043] A guide plate 38 is fixedly installed on the assembly base 1 near the loading side, and a guide roller 39 is provided above the assembly base 1 near the conveyor belt 3. The cloth placed on the guide plate 38 moves between the guide roller 39 and the guide plate 38. The guide roller 39 applies pressure to the cloth to ensure that the cloth is flush with the upper surface of the conveyor belt 3 to realize the transportation of the cloth.

[0044] Working principle:

[0045] The first step: according to the width of the cloth, the corresponding components on the assembly base 1 are adjusted, and the adjusting screw 25 is screwed. The rotation of the adjusting screw 25 drives the side telescopic frame 23 to move in the top assembly plate 2. When the side telescopic frame 23 moves in the top assembly plate 2, it drives the structure on the side telescopic frame 23 to move, and the cloth pressing wheel 31 arranged on the side telescopic frame 23 reaches the corresponding position on both sides of the cloth, and the piston rod of the third electric push rod 27 drives the lifting sleeve 28 to descend, and the lifting sleeve 28 descends and drives the cloth pressing wheel 31 to descend, and the cloth pressing wheel 31 is pressed on the corresponding positions on both sides of the cloth. At the same time, the cloth pressing wheel 31 and the inner telescopic plate 29 transmit the pressure to the reset spring 30 due to the pressure, and the deformation of the reset spring 30 is used to buffer the pressure of the cloth pressing wheel 31 on the cloth. At the same time, the cloth is transported along the upper surface of the guide plate 38, and the cloth reaches the upper surface of the conveyor belt 3 under the guidance of the guide plate 38 and the guide roller 39.

[0046] Step 2: The corresponding part of the cloth transported by the conveyor belt 3 reaches the lower surface of the lower assembly plate 13, and the conveyor belt 3 stops transporting the cloth. The piston rod of the first electric push rod 6 drives the mounting sleeve 7 and the upper mounting plate 9 to descend. The descent of the upper mounting plate 9 also drives the lower assembly plate 13 to descend. At the same time, the piston rod of the inner mounting frame 17 of the conveyor belt 3 also drives the lower U-shaped assembly frame 19 and the upper U-shaped assembly frame 20 to rise. The upper U-shaped assembly frame 20 rises and contacts the top of the inner wall of the conveyor belt 3. The lower assembly plate 13 descends and contacts the cloth above the conveyor belt 3. The pressure ring 15 first contacts the upper surface of the cloth. After the pressure ring 15 contacts the cloth, the pressure ring 15 and the lifting ring 12 are pressed and move upward. The special cutting knife 16 under the upper mounting plate 9 extends out through the lower assembly plate 13. At the same time, the lifting ring 12 is pressed against the buffer spring 1 The pressure is applied to drive the buffer spring 14 to deform, the special cutting knife 16 extends out and contacts the cloth, the upper mounting plate 9 heats the special cutting knife 16, and the special cutting knife 16 cuts the cloth, the lower U-shaped assembly frame 19 and the upper U-shaped assembly frame 20 are supported at the corresponding position of the inner wall of the conveyor belt 3, and the structure composed of the lower U-shaped assembly frame 19 and the upper U-shaped assembly frame 20 will also deform, and the conveyor belt 3 is supported by the upper U-shaped assembly frame 20 to improve the strength of the conveyor belt 3 to ensure that the cloth has enough objects to support it when it is cut, and the structure composed of the V-shaped elastic plate 21 and the buffer wheel 22 can be deformed to adapt to the deformation of the upper U-shaped assembly frame 20 and the lower U-shaped assembly frame 19. After the cutting is completed, the second electric push rod 18 and the first electric push rod 6 work, and the cloth is no longer cut.

[0047] Step 3: By turning the adjusting screw 37, the extension and retraction of the telescopic card strip 36 is adjusted. When the telescopic card strip 36 is retracted, the lifting bar 33 can be raised and lowered. When the telescopic card strip 36 is extended, the lifting bar 33 is fixed. The lifting and lowering of the lifting bar 33 drives the air cooling device 34 to rise and fall, thereby adjusting the distance between the air cooling device 34 and the cloth on the upper surface of the conveyor belt 3, ensuring the cooling effect of the air cooling device 34 on the cloth.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
