Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric processing technology, and in particular to a nonwoven fabric tote bag processing device. Background Technology

[0002] Nonwoven fabric is a type of non-woven material. It is made by directly forming fibers from polymer chips, short fibers, or filaments into a web through airflow or mechanical means, then reinforcing it through hydroentangling, needle punching, or thermal rolling, and finally finishing processes to form a non-woven fabric. It is a new type of fiber product with a soft, breathable, and planar structure. Its advantages include no fiber shedding, strength, durability, silky softness, and it is also a type of reinforcing material, possessing a cotton-like feel. Compared to cotton fabrics, nonwoven bags are easier to shape and cheaper to produce. However, during the production process, the surface of nonwoven bags has raised threads, which negatively impacts subsequent printing processes. Therefore, these threads need to be removed. Currently, fixing nonwoven bags is somewhat inconvenient, thus reducing work efficiency.

[0003] For example, a nonwoven tote bag processing device disclosed in Chinese patent literature (publication number: CN222769090U) uses a fixing bolt, a bag clamping plate, a sliding plate and a fixing clamping plate. By rotating the fixing bolt, the distance between the bag clamping plate and the sliding plate is increased. Then, the sliding plate is slid so that the distance between the upper and lower sliding plates is just enough to clamp the nonwoven bag whose thread ends need to be removed. Then, the upper and lower ends of the nonwoven bag are respectively clamped between the bag clamping plate and the fixing clamping plate. Finally, the fixing bolt is tightened to fix the nonwoven bag.

[0004] However, in actual operation, since the fixing plate is set vertically, when fixing the non-woven bag, it must first be passed through the clamping plate, then the non-woven bag is flattened and held, and then the other employee tightens the fixing bolts in turn before the thread removal operation can be carried out. The whole process requires two employees to cooperate, and the steps are cumbersome, which seriously reduces the processing efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. Currently, when processing non-woven bags to remove loose threads, the fixing process requires two people to work together, which is cumbersome and reduces processing efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A non-woven fabric tote bag processing device includes a processing table, a movable groove is provided above the processing table, a movable adjustment mechanism is provided inside the movable groove, and the movable adjustment mechanism includes a lead screw, one end of which is rotatably connected to the rear inner wall of the movable groove through a bearing;

[0008] The other end of the lead screw passes through and extends to the front of the processing table. A first servo motor is fixedly installed on the front of the processing table.

The inner walls of the two support blocks are rotatably connected to rotating rods via bearings.

[0013] Preferably, a gear is fixedly sleeved on the outside of the rotating rod, and symmetrically distributed connecting blocks are fixedly sleeved on the outside of the rotating rod. A placement plate is fixedly connected to the upper end of each of the two connecting blocks, and a second servo electric cylinder is fixedly installed on the upper end of the moving block.

[0014] Preferably, a rack is fixedly connected to one end of the piston rod of the second servo electric cylinder, the tooth surface of the rack meshes with the tooth surface of the gear, the lower end of the rack slides in contact with the upper end of the moving plate, and a third servo electric cylinder is fixedly installed at the lower end of the placement plate.

[0015] Preferably, one end of the piston rod of the third servo electric cylinder is fixedly connected to a lifting plate, and the upper end of the lifting plate is fixedly connected to symmetrically distributed movable rods.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] In this invention, by using the combined use of the moving adjustment mechanism and the flipping mechanism, when the placement plate is in a horizontal state, the operator can directly lay the non-woven bag flat on the placement plate. The pressure plate is driven vertically downward by the third servo electric cylinder to quickly clamp and fix both ends of the bag, reducing bag wrinkles and displacement caused by manual adjustment. There is no need for manual bag insertion, flattening, or two people to tighten the fixing bolts. It can be completed by a single person, reducing the difficulty of operation and thus improving work efficiency. Attached Figure Description

[0028] Example

[0029] like Figure 1-4 As shown, this utility model provides a technical solution: a non-woven fabric tote bag processing device, including a processing table 1. The processing table 1 is made of high-strength cast iron and has good rigidity and stability. A moving groove 2 is milled on the top of the processing table 1. A moving adjustment mechanism is set inside the moving groove 2. The moving adjustment mechanism includes a lead screw 3. The lead screw 3 is made of high-quality alloy steel and has been precision machined and heat-treated to have high strength and wear resistance. One end of the lead screw 3 is rotatably connected to the rear inner wall of the moving groove 2 through a high-precision bearing to ensure smooth rotation of the lead screw 3.

[0030] The other end of the lead screw 3 passes through and extends to the front of the processing table 1. The front of the processing table 1 is fixedly mounted with a first servo motor 31 by bolts. The first servo motor 31 has the characteristics of high precision and high torque, and can accurately control the rotation of the lead screw 3. The output shaft of the first servo motor 31 is fixedly connected to the other end of the lead screw 3 through a flexible coupling to ensure the stability of power transmission. The lead screw 3 is externally threaded with a threaded block 32. The threaded block 32 is made of wear-resistant material and has high precision in matching with the lead screw 3. It can convert the rotational motion of the lead screw 3 into linear motion. The upper end of the threaded block 32 is fixedly connected with a mounting block 33 by welding. The mounting block 33 is used to install the flipping mechanism.

[0031] The upper end of the mounting block 33 is provided with a guide groove 34 by milling. The inner wall of the guide groove 34 is finely polished with low roughness to ensure smooth sliding. The inner wall of the guide groove 34 is slidably connected to a guide slider 35. The guide slider 35 is made of high-strength aluminum alloy and the surface is anodized, which has good wear resistance and corrosion resistance.

[0032] A first servo electric cylinder 36 is fixedly installed on one side of the inner wall of the guide slide 34 by bolts. The first servo electric cylinder 36 has the characteristics of high precision and high speed, and can accurately control the movement of the guide slider 35. One end of the piston rod of the first servo electric cylinder 36 is fixedly connected to one side of the guide slider 35 to ensure a firm connection and flexible transmission.

[0033] The flipping mechanism includes a movable plate 4, which is welded from steel plate and has high strength and rigidity. The lower end of the movable plate 4 is fixedly connected to the upper end of the guide slider 35 by bolts and can move together with the guide slider 35. The upper end of the movable plate 4 is fixedly connected by welding to symmetrically distributed support blocks 41. The support blocks 41 are made of cast steel and have good load-bearing capacity. The inner walls of the two support blocks 41 are rotatably connected to rotating rods 42 through high-precision bearings.

[0034] A gear 43 is fixedly connected to the outside of the rotating rod 42 via a key. The gear 43 is made of high-quality alloy steel and has undergone precision machining and heat treatment, resulting in high hardness and wear resistance. A symmetrically distributed connecting block 44 is also fixedly connected to the outside of the rotating rod 42 via welding. The upper ends of the two connecting blocks 44 are fixedly connected to a placement plate 45 by bolts. The placement plate 45 is made of aluminum alloy sheet with an anti-slip surface treatment, which can effectively fix the non-woven bag. A second servo electric cylinder 46 is fixedly installed on the upper end of the moving plate 4 by bolts. The second servo electric cylinder 46 can precisely control the flipping action.

[0035] One end of the piston rod of the second servo electric cylinder 46 is fixedly connected to a rack 47 by bolts. The rack 47 meshes precisely with the tooth surface of the gear 43, which can convert the linear motion of the second servo electric cylinder 46 into the rotational motion of the gear 43. The lower end of the rack 47 slides in contact with the upper end of the moving plate 4. The lower end of the placement plate 45 is fixedly installed with a third servo electric cylinder 48 by bolts. The third servo electric cylinder 48 is used to drive the lifting and lowering of the pressure plate 411.

[0036] One end of the piston rod of the third servo electric cylinder 48 is fixedly connected to a lifting plate 49 by bolts. The upper end of the lifting plate 49 is fixedly connected by welding to symmetrically distributed movable rods 410. The movable rods 410 are made of stainless steel with a smooth surface and can slide smoothly in the through holes on the placement plate 45. One end of the movable rods 410 extends through to the top of the placement plate 45 and is fixedly connected to a pressure plate 411 by bolts. The bottom surface of the pressure plate 411 is attached with a silicone pad, which can prevent the fabric from being pinched when clamping the non-woven bag, while ensuring uniform clamping force.

[0037] A collection slot 5 is milled into the top of the processing table 1 to collect the cut thread ends. A fixed bracket 6, made of high-strength steel, is welded and fixed to the top of the processing table 1, providing good support strength. A second servo motor 61 is bolted to the upper end of the fixed bracket 6. The output shaft of the second servo motor 61 is fixedly connected to a cutting shaft 62 via a flexible coupling. The cutting shaft 62 is made of alloy steel and has sharp cutting blades mounted on its surface, which can effectively cut the thread ends on the surface of the non-woven bag. One end of the cutting shaft 62 passes through the fixed bracket 6 and is rotatably connected to the upper end of the processing table 1 through a high-precision bearing, ensuring smooth rotation of the cutting shaft 62.

[0038] The working process of this utility model:

[0039] Step 1: The operator lays the non-woven bag flat on the horizontal placement plate 45. The anti-slip texture on the surface of the placement plate 45 is used to initially fix the position of the bag, ensuring that the fabric is flat and wrinkle-free. The third servo electric cylinder 48 is activated, and the piston rod extends downward, driving the pressure plate 411 to press vertically down through the movable rod 410, pressing the edge of the bag tightly onto the placement plate 45. A silicone pad is used between the pressure plate 411 and the placement plate 45 to avoid damaging the fabric and to ensure uniform clamping force. The piston rod of the second servo electric cylinder 46 retracts, pulling the rack 47 to move horizontally. The rack 47 meshes with the gear 43 to drive the rotating rod 42 to rotate. When the rotating rod 42 drives the placement plate 45 to rotate 90° to a vertical position, the second servo electric cylinder 46 stops. The rack 47 and the gear 43 achieve mechanical locking through tooth surface meshing to prevent shaking during processing.

[0040] Step two: The piston rod of the first servo electric cylinder 36 extends, pushing the guide slider 35 forward along the guide groove 34, causing the moving plate 4 and the vertically positioned non-woven bag to approach the cutting shaft 62. The second servo motor 61 drives the cutting shaft 62 to rotate at high speed. When its circumferential cutting edge contacts the surface of the bag, it uses the difference in linear velocity to cut off the protruding thread ends. The first servo motor 31 synchronously drives the lead screw 3 to reciprocate, and the threaded block 32 drives the mounting block 33 to reciprocate linearly along the axis of the lead screw 3, causing the bag to move left and right during the cutting process, ensuring that all surface thread ends are completely cut. After cutting, the thread ends fall into the collection trough 5 due to gravity. A negative pressure pipe is connected below the collection trough 5, which is linked to the central dust removal system or an independent vacuum cleaner in the workshop. Airflow draws the debris into the dust collection box, achieving simultaneous cutting and collection. After processing, the piston rod of the second servo electric cylinder 46 extends, pushing the rack 47 to move in the opposite direction. The rotating rod 42 drives the placement plate 45 to rotate 90° back to a horizontal position. The piston rod of the third servo electric cylinder 48 retracts, and the pressure plate 411 lifts. The operator removes the processed non-woven bag, puts in new material, and repeats the above process. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
