[0004] When the device is working and the part to be cut is moved into place, the motor needs to be turned off to stop the movement of the conveyor belt to complete the cutting. Furthermore, in order to complete the overall processing, the motor and the conveyor belt need to be started multiple times, resulting in low work efficiency and certain usage limitations.

[0005] Therefore, it is necessary to provide a processing device and a processing method for a drawstring inner bag to solve the above technical problems. Summary of the invention

[0006] The purpose of the present invention is to provide a processing device and a processing method for a drawstring inner bag, so as to solve the problem that in order to complete the overall processing in the above-mentioned background technology, the motor and the conveyor belt need to be started multiple times, resulting in low work efficiency.

DETAILED DESCRIPTION

[0034] Embodiment 1:

[0035] See also Figure 1 to Figure 2 The embodiment of the present invention provides a processing device for a lacing inner bag, which is mainly used to improve the processing efficiency of the lacing inner bag. The processing device includes a workbench 1 and a discharge mechanism 2 arranged on the workbench 1 and used to convey materials. In this embodiment, the discharge mechanism 2 is an existing mature technology and is not described in detail here. A conveying component 3 for driving the movement of materials is arranged on the workbench 1 and at a position corresponding to the discharge mechanism 2. A transmission component 4 connected to the transmission component 3 and a moving component 5 movably engaged with the transmission component 4 are arranged on the workbench 1.

[0036] In this embodiment, Figure 1 From the perspective of , the material discharge mechanism 2 is located on the left side, the transmission component 4 is located on the front left side of the conveying component 3, and the moving component 5 is also located on the left side when it is in the initial position. When the material discharge mechanism 2 and the conveying component 3 are started, the material begins to be discharged and moves from left to right with the transport component. The conveying component 3 also drives the moving component 5 to move right synchronously through the transmission component 4. The moving component 5 cuts the material during the rightward movement, so that the whole machine can be operated without stopping. After the cutting is completed, the conveying component 3 drives the moving component 5 to move left and reset through the transmission component 4 to prepare for the next cutting work.

[0037] See also Figures 1 to 5 In this embodiment, preferably: the conveying assembly 3 includes a first roller 301 and a second roller 303 that are rotatably matched with the workbench 1, and the outer surfaces of the first roller 301 and the second roller 303 are jointly sleeved with a conveyor belt 302 (the surface of the conveyor belt 302 is provided with a cutting groove that is adapted to the cutting mechanism 2, which is not shown in the figure), and the conveyor belt 302 corresponds to the position of the discharge mechanism 2 and can play a role in receiving and conveying the material. In order to achieve overall drive, a motor 304 that is fixedly connected to the workbench 1 is fixedly installed at the front end of the first roller 301; at the same time, a first pulley 305 that is transmission-connected to the transmission assembly 4 is fixedly installed at the front end of the second roller 303. When the motor 304 drives the first roller 301 and the second roller 303 to rotate, the transmission assembly 4 can be driven to work through the first pulley 305.

[0038] Furthermore, the transmission assembly 4 includes a support rod 401 detachably connected to the workbench 1, a second pulley 402 is rotatably mounted on the front end of the support rod 401, a belt 403 is sleeved on the outer surfaces of the first pulley 305 and the second pulley 402, and a protrusion 404 that is movably engaged with the moving assembly 5 is fixedly mounted on the front surface of the belt 403; when the first pulley 305 drives the second pulley 402 to rotate through the belt 403, the protrusion 404 moves in a circular trajectory with the belt 403 and drives the moving assembly 5 to achieve left and right reciprocating movement. At the same time, the size of the first pulley 305 can be adjusted to adjust the amount of movement of the protrusion 404 with the belt 403 when the material is fed to the right, thereby controlling the movement stroke of the moving assembly 5 driven by the protrusion 404.

[0039] In the above structure, the support rod 401 is detachably connected to the workbench 1 by bolts, and mounting holes arranged in a rectangular array are provided on the surface of the workbench 1. The mounting holes are parallel to the moving direction of the material (horizontally left and right), so that the support rod 401 and the second pulley 402 can move left and right in the horizontal direction (relatively close to / away from the first pulley 305). During the left and right movement of the second pulley 402 and the support rod 401, in order to ensure the tension of the belt 403, a tensioning wheel that is movably fitted with the belt 403 is provided inside the workbench 1, and the tensioning wheel is abutted against the bottom of the belt 403 to achieve continuous tensioning of the belt 403. In this embodiment, the mounting hole and the tensioning wheel are not shown, and the tensioning wheel is an existing mature technology and is not described in detail here. The above design can change the stroke of the moving component 5 in the left and right moving direction, thereby changing the cutting position of the material to meet the cutting requirements of materials of different sizes.

[0040] Furthermore, the moving assembly 5 includes a bracket 501 that is slidably matched with the workbench 1. The bracket 501 is designed in an inverted U shape and has a vertical slot 502 therein. The bracket 501 is slidably mounted with a slider 503 through the vertical slot 502. The slider 503 is hollow and is just sleeved on the outside of the protrusion 404. When the protrusion 404 moves to the right along the upper side of the belt 403, the slider 503 drives the bracket 501 to move to the right synchronously. When the protrusion 404 is ready to move to the lower side of the belt 403 along the semicircular edge on the right side of the belt 403, the protrusion 404 can drive the slider 503 to vertically descend along the vertical slot 502. When the protrusion 404 moves to the left along the lower side of the belt 403, the slider 503 drives the bracket 501 to move to the left and reset. Among them, an electric push rod 504 is also fixedly installed on the inner top wall of the bracket 501, and a cutting mechanism 505 corresponding to the position of the conveyor belt 302 is fixedly installed on the output end of the electric push rod 504. When the electric push rod 504 drives the cutting mechanism 505 to descend, the material on the conveyor belt 302 can be cut. In this embodiment, the cutting mechanism 505 is an existing mature technology and will not be described in detail here.

[0041] When in use, the discharge mechanism 2 and the motor 304 are started, and the material is driven to move to the right through the first roller 301, the second roller 303 and the conveyor belt 302. The first roller 301 drives the protrusion 404 to move along the circular trajectory of the belt 403 through the first pulley 305, the second pulley 402 and the belt 403. When the protrusion 404 is on the upper side of the belt 403, it drives the bracket 501, the electric push rod 504 and the cutting mechanism 505 to move to the right through the slider 503. During the rightward movement, the electric push rod 504 is started to drive the cutting mechanism 505 to descend. When the cutting mechanism 505 contacts the material, the bracket 501 still maintains the trend of driving the electric push rod 504 and the cutting mechanism 505 to move to the right. At this time, the cutting mechanism 505 maintains the rightward movement process and cooperates with the conveyor belt 302 to complete the cutting of the material (at this time, the protrusion 404 has not entered the lower side of the belt 403 along the semicircular edge on the right side of the belt 403). When the electric push rod 504 drives the cutting mechanism 505 to rise, the protrusion 404 has moved to the lower side with the belt 403. At this time, the conveyor belt 302 continues to move to the right to transport materials, and the protrusion 404 drives the electric push rod 504 and the cutting mechanism 505 to reset to the left through the slider 503 and the bracket 501. After passing the semicircular plate on the left side of the belt 403, the protrusion 404 moves to the upper side of the belt 403 again, and at this time it can drive the slider 503 and the bracket 501 to move right, and so on.

[0042] In summary, through the cooperation of the structures such as the protrusion 404, the slider 503, the first pulley 305 and the first roller 301, when the first roller 301 provides power for the conveyor belt 302 to transport materials, the first pulley 305 can also provide power for the movement of the belt 403, so that the protrusion 404 can be moved back and forth with the movement of the belt 403, so that the cutting mechanism 505 can complete the descending cutting while maintaining the synchronous rightward movement, and the material can be quickly cut without stopping the movement of the conveyor belt 302, which effectively improves the processing efficiency. At the same time, the loss and safety risk of the conveyor belt 302 are reduced without the need to start and stop the conveyor belt 302 many times. The cutting mechanism 505 can vertically descend to contact the upper surface of the material and realize cutting during the rightward movement. Compared with the background technology, it can reduce the bending deformation caused by moving from the side to the other side, and thus the overall cutting quality can be guaranteed during the processing of the device, which is more practical.

[0043] Embodiment 2:

[0044] See also Figures 1 to 6 On the basis of the first embodiment, in order to further ensure the cutting effect of the material, a base 6 (from Figure 6The base 6 is also U-shaped when viewed from the right side. A pressing component 7 corresponding to the position above the conveyor belt 302 is slidably provided on the surface of the base 6. When the material is discharged through the discharge mechanism 2 and moves to the right with the conveyor belt 302, the upper surface of the material can contact the pressing component 7. The pressing component 7 can achieve a belt pressing positioning effect on the material.

[0045] A pressing plate 506 corresponding to the position of the material pressing component 7 is fixedly installed on the surface of the cutting mechanism 505 and near the upper side. When the cutting mechanism 505 is about to come into contact with the material, the pressing plate 506 comes into contact with the material pressing component 7, driving the material pressing component 7 to move obliquely to the lower right ( Figure 5 Perspective), the conveyor belt 302 is used to tension the movable side of the right end of the material, while the left side of the material is tensioned by the discharge mechanism 2. At this time, the cutting mechanism 505 can ensure the cutting quality when it descends to complete the cutting.

[0046] See also Figures 1 to 7 In this embodiment, preferably: the material pressing assembly 7 includes a connecting rod 701 that is slidably matched with the base 6. The connecting rod 701 is U-shaped and has partitions 702 fixedly installed at both ends. The opposite sides of the two partitions 702 are rotatably provided with pressure rollers 703 corresponding to the upper position of the conveyor belt 302. When the material moves to the right, its upper surface contacts the pressure roller 703 to achieve material pressing. In this embodiment, two pressure rollers 703 are provided, and the number of pressure rollers 703 can be increased as needed to ensure the material pressing effect. At the same time, a first spring 704 is fixedly installed between the bottom of the connecting rod 701 and the base 6. Under the action of the first spring 704, there is a tendency to drive the connecting rod 701 to move downward, so that the connecting rod 701 drives the partition 702 and the pressure roller 703 to move downward and contact the material well.

[0047] In the above structure, the front end of the connecting rod 701 extends upward and corresponds to the pressure plate 506 up and down. When the pressure plate 506 descends, it pushes the connecting rod 701 to descend, so that the connecting rod 701 drives the pressure roller 703 to descend synchronously through the partition 702 and squeeze the first spring 704; and the front end of the connecting rod 701 extends upward, so that the pressure plate 506 will not interfere with the movement of the partition 702 and the pressure roller 703 when it descends.

[0048] Furthermore, a guide groove 601 is provided on the surface of the base 6 for the sliding of the connecting rod 701. In this embodiment, the guide groove 601 is an inclined groove, and the angle between the side of the inclined groove close to the discharge mechanism 2 and the upper surface of the conveyor belt 302 is set at an acute angle, so that when the connecting rod 701 descends under the action of the pressure plate 506, it can move obliquely to the lower right along the inclined groove.

[0049] When in use, the material is driven to move rightward and the cutting mechanism 505 is driven to move back and forth left and right through the cooperation of the first roller 301, the first pulley 305, the protrusion 404 and the bracket 501. The cutting mechanism 505 is lowered to complete the cutting when it moves rightward synchronously with the material. The working process and effect of this part are the same as those in the first embodiment, and will not be repeated here. The difference is that when the material moves rightward along the conveyor belt 302, it can contact the pressure roller 703 and enter between the pressure roller 703 and the conveyor belt 302. The rotating pressure roller 703 plays a belt-pressing positioning effect on the material, reducing the material's streamers and deviations. When moving to the right, the cutting mechanism 505 drives the pressure plate 506 to descend synchronously. When the cutting mechanism 505 is about to contact the material, the pressure plate 506 contacts the connecting rod 701, driving the connecting rod 701 to move obliquely to the lower right along the guide groove 601. The connecting rod 701 drives the pressure roller 703 to move synchronously through the partition plate 702. With the support of the conveyor belt 302, effective tensioning of the right side of the material can be achieved. At this time, the further descent of the cutting mechanism 505 can achieve rapid cutting of the material and ensure the cutting quality (although the pressure plate 506 will drive the connecting rod 701 to continue to tilt and descend at this time, the material moves less in the up and down directions due to the support of the conveyor belt 302 on the material, and the cutting mechanism 505 can still complete the cutting process).

[0050] In the first embodiment, the cutting is completed by driving the cutting mechanism 505 to descend while moving right synchronously with the material. Although the conveyor belt 302 can be processed without stopping, the right side of the material (the side away from the discharge mechanism 2) is not limited. Therefore, as the cutting mechanism 505 descends and cuts, the area in contact with the cutting mechanism 505 will bend and deform, thereby causing dimensional errors in the cutting process and affecting the cutting quality. There are certain limitations in use.

[0051] Compared with the first embodiment, through the cooperation of the structures such as the base 6, the connecting rod 701, the pressure roller 703 and the pressure plate 506, when the cutting mechanism 505 descends to prepare for cutting, the pressure roller 703 can be driven to move obliquely away from the discharge mechanism 2 and close to the conveyor belt 302, and then cooperate with the upper surface of the conveyor belt 302 to achieve effective tensioning of the right side of the material (the side away from the discharge mechanism 2), so that the cutting mechanism 505 can complete rapid cutting on the basis of material tensioning, avoiding bending deformation in the contact area with the cutting mechanism 505, which can effectively reduce the dimensional error during cutting and further ensure the cutting quality of the material. At the same time, the setting of the pressure roller 703 cooperates with the first spring 704 to adapt to the upper and lower thickness of the material. When the material enters between the pressure roller 703 and the conveyor belt 302, the first spring 704 provides downward pressure for the pressure roller 703, which plays a role in the belt positioning effect of the material, which can effectively prevent the material from running off and streamers, and achieve a multifunctional effect; the overall operation is combined with the movement of the cutting mechanism 505 and the setting of the conveyor belt 302, and the applicability is stronger.

[0052] Embodiment three:

[0053] See also Figures 1 to 9 On the basis of the second embodiment, in order to further ensure the conveying of the material by the conveyor belt 302, the pressure roller 703 includes a short rod 7031 rotatably connected to the partition 702, and a roller 7032 is fixedly installed at the end of the short rod 7031 away from the partition 702. The short rods 7031 of the two pressure rollers 703 are synchronously rotated by a belt transmission 7033, and a second gear 7034 is fixedly installed on the outer surface of the short rod 7031 near the material discharge mechanism 2. Of course, the belt transmission 7033 in this embodiment can also be replaced by a chain transmission.

[0054] Furthermore, the support rod 401 is designed in a front and rear two-stage design, the rear end of which is detachably connected to the workbench 1, while the front end is rotatably connected to the rear end and is used to place the second pulley 402. A first gear 405 that meshes with the second gear 7034 is also fixedly installed on the outer surface of the front end, so that when the front end rotates, the second gear 7034 can be driven to rotate synchronously through the first gear 405, and then the synchronous rotation of the overall short rod 7031 and the roller 7032 is achieved through the belt transmission 7033. Because the moving direction of the belt 403 is synchronized with the conveyor belt 302 (clockwise movement), the roller 7032 located above the conveyor belt 302 needs to be opposite to the conveyor belt 302 (counterclockwise rotation), so that a good material conveying effect can be achieved, so the first gear 405 and the second gear 7034 are set to make the short rod 7031 and the roller 7032 achieve the effect of being opposite to the conveyor belt 302.

[0055] See also Figures 1 to 10 In this embodiment, it is preferred that: the conveyor belt 302 has front and rear sides, so in order to ensure the conveying effect, the roller 7032 corresponding to the pressure roller 703 is also on the front and rear sides. At this time, two second gears 7034 are provided and are fixedly mounted on the front end of the support rod 401 (at this time, the front and rear length dimension of the front end of the support rod 401 is greater than the front and rear length dimension of the conveyor belt 302).

[0056] Furthermore, since the connecting rod 701 will drive the short rod 7031, the roller 7032 and the second gear 7034 to move along the guide groove 601 through the partition 702, and the first gear 405 and the second gear 7034 must be kept in meshing, the guide groove 601 in this embodiment has an arcuate edge 602, and the virtual circle where the arcuate edge 602 is located is concentric with the virtual circle where the first gear 405 is located; at the same time, a top rod 705 that is movably fitted with the arcuate edge 602 is fixedly installed on the surface of the connecting rod 701 close to the first gear 405, and a second spring 706 that is in contact with the guide groove 601 is fixedly installed on the surface of the connecting rod 701 away from the top rod 705. The second spring 706 is not connected to the guide groove 601 but can keep the top rod 705 in a fit state with the arcuate edge 602 through the connecting rod 701. When the pressing plate 506 pushes the connecting rod 701 to descend, the connecting rod 701 is lowered in an arc shape through the push rod 705 and the arc edge 602, thereby driving the second gear 7034 to move clockwise along the first gear 405 and maintain a meshing state.

[0057] In the above structure, the contact between the top rod 705 and the arc-shaped edge 602 is located on the upper side of the right quarter of the arc-shaped edge 602 ( Fig.10 In this case, the top rod 705 can maintain the overall tendency of being tilted to the lower right when driving the connecting rod 701 to descend, and can also make the second gear 7034 revolve around the first gear 405 and maintain meshing.

[0058] When in use, the first roller 301, the first pulley 305, the convex block 404 and the bracket 501 drive the material to move right and drive the cutting mechanism 505 to move back and forth. The cutting mechanism 505 moves right synchronously with the material and descends to complete the cutting. The base 6, the connecting rod 701 and the pressing plate 506 are used to tighten the right side of the material to ensure the cutting quality. The working process and effect of this part are the same as those in the second embodiment, and will not be repeated here. The difference is that when the first roller 301 drives the second pulley 402 to rotate through the first pulley 305 and the belt 403, the second pulley 402 drives the second gear 7034 to rotate synchronously through the front end of the support rod 401, and the second gear 7034 drives the roller 7032 to rotate in the opposite direction of the conveyor belt 302 through the first gear 405 and the short rod 7031. At this time, if the material enters between the roller 7032 and the conveyor belt 302, it can be quickly transported. When the pressure plate 506 pushes the connecting rod 701 downward, the connecting rod 701 drives the partition 702, the short rod 7031, the roller 7032 and the second gear 7034 to move obliquely to the lower right along the arc edge 602 through the top rod 705 and the second spring 706, so that the roller 7032 can cooperate with the conveyor belt 302 to achieve tension on the right side of the material on the basis of continuous rotation, so that the second gear 7034 can revolve along the first gear 405 and still maintain meshing transmission.

[0059] In the second embodiment, the pressure roller 703 and the first spring 704 are arranged so that the pressure roller 703 can play a role in pressing the material and tensioning it during cutting. After the material is cut by the cutting mechanism 505, the material on the right side of the cutting mechanism 505 (i.e., the cut material) will be subject to the squeezing force and friction force of the pressure roller 703 (the effect of the first spring 704), and thus cannot keep pace with the movement of the conveyor belt 302, and will interfere with the material on the left side that has not been cut, which has certain limitations in use.

[0060] Compared with the second embodiment, through the cooperation of structures such as the first gear 405, the second gear 7034, the arc plate and the top rod 705, under the premise of ensuring that the roller 7032 moves obliquely to the lower right for tensioning, the revolution of the second gear 7034 relative to the first gear 405 can drive the roller 7032 to rotate in the opposite direction of the conveyor belt 302, and then cooperate with the conveyor belt 302 to achieve synchronous transportation of materials (cut materials and uncut materials), and can maintain synchronization both in the normal moving state and in the pressure tension state, effectively avoiding interference between the cut materials and the uncut materials, and facilitating timely observation and subsequent material collection and reprocessing; the overall operation is combined with the rotation of the second pulley 402 and the movement of the connecting rod 701 to meet more requirements in actual use.
