They are suitable for any company and any industry as advertising and gifts. The product is made of non-woven fabrics, which is a new generation of environmentally friendly materials. It is moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in colors, low in price, and recyclable.

[0003] The material can be naturally decomposed in 90 days when placed outdoors, and has a service life of up to 5 years when placed indoors. It is non-toxic, odorless, and has no residual substances when burned, thus not polluting the environment. It is internationally recognized as an environmentally friendly product that protects the earth's ecology. Traditional non-woven bags are usually processed using non-woven bag processing equipment;

[0004] However, the non-woven bag has a handle that can be used, and the traditional processing equipment does not have a device for automatically installing the handle. Therefore, after the non-woven bag is processed, the handle ring needs to be manually installed on the non-woven bag, which not only reduces the processing efficiency, but also consumes more labor costs;

[0005] Aiming at the shortcomings of traditional non-woven bag processing equipment and the problem of automatic and precise docking of handle straps with non-woven bags, a handle forming device for non-woven bag making machines is proposed. Summary of the invention

[0006] The embodiments according to the present invention are intended to solve or improve at least one of the above technical problems.

[0007] A first object of an embodiment of the present invention is to provide a handle forming device for a non-woven bag making machine.

[0008] An embodiment of the first aspect of the invention provides a handle forming device for a non-woven bag making machine, comprising a base; a material pulling mechanism, longitudinally corresponding to the base, and horizontally installed on an external wall; a cutting material supporting mechanism, which is slidably installed on the base and laterally corresponds to the bottom end of the material pulling mechanism; and a bending mechanism, which is slidably connected to the base; wherein two bending mechanisms are provided and are arranged between the bottom end of the material pulling mechanism and the cutting material supporting mechanism, and the two bending mechanisms move in opposite directions on the base, and the cutting material supporting mechanism is used for supporting and shearing the material strip.

[0009] According to a handle forming device for a non-woven bag making machine provided by the present invention, the material strip conveyed by the external material strip conveyor can be supported, transmitted and sheared through the cutting support mechanism, so as to control and guide the single-segment length of the material strip during processing; the material strip can be pulled at one end of the cutting support mechanism through the pulling mechanism, and the processing length of the material strip can be controlled by the moving distance of the bottom end of the pulling mechanism, so as to process different types of handles; the long strip of material can be rotated and bent at two points through two provided bending mechanisms, so as to transform and process the long strip of material into a U shape, and the bottom end of the pulling mechanism and the cutting support mechanism can be connected to each other. Between the mechanisms, the two bending mechanisms move in opposite directions on the base, so that the length of the hand-holding part of the handle forming part of the material strip can be adjusted, so as to adapt to the change of the pulling part width of different non-woven bags. The opposite moving directions make the center position between the two pulling mechanisms unchanged, so as to keep the lengths of the two ends of the handle equal during the change and adjustment. The cutting material supporting mechanism is slidably installed on the base, so that the cutting material supporting mechanism can move when supporting different material strip widths, so that the axis of the material strip always corresponds to the center between the bending parts of the bending mechanism, avoiding the occurrence of asymmetry at the two ends of the handle after bending.

[0010] In addition, the technical solution provided according to the embodiment of the present invention may also have the following additional technical features:

[0012] In this technical solution, through the relative rotation of the two transmission rods and the front-rear sliding connection between the guide slide seats, the two bending mechanisms can move to equal lengths when the horizontal movement directions are opposite, so that when the length of the gripping part of the handle changes, the lengths of the hanging parts at both ends are the same, so as to facilitate the connection of the external bag body, and after the connection, the bag body will not be tilted when a person pulls it by hand.

[0020] In this technical solution, the exposed width of the supporting plate is changed through the sliding connection between the supporting plate and the clamping seat so as to adapt to different widths of the material strip. The sliding of the clamping seat can realign the axis of the material strip after adapting to different widths of the material strip so as to perform bending operations. The cutting tool is controlled by the cutting drive cylinder so that the two cutting tools can shear and break the material strip passing between them so as to continuously process a single section of the material strip.

[0022] In this technical solution, a ball screw slide is used and in cooperation with a material pulling drive cylinder to clamp one end of the material strip and then pull it. The cutting length of the material strip can be selected by selecting the moving length of the moving end of the ball screw slide, so that the size of the handle required for different bag bodies can be processed.

[0023] In any of the above technical solutions, the material pulling mechanism further includes: a clamping block, which is rotatably mounted on the moving end of the material pulling drive cylinder, and the left side wall of the clamping block is rotatably connected to the side wall of the transmission frame.

[0024] In this technical solution, the clamping block is rotatably installed with the moving end of the material pulling drive cylinder and the side wall of the transmission frame respectively, so that the clamping block can press down and clamp the material strip in a rotating form, making each rotation and downward clamping of the clamping block more stable and accurate, avoiding the deviation of the clamping block.

[0041] According to a handle forming device for a non-woven bag making machine provided by the present invention, the material strip conveyed by the external material strip conveyor can be supported, transmitted and sheared through the cutting support mechanism 3, so as to control and guide the single-segment length of the material strip during processing; the material pulling mechanism 2 can pull the material strip at one end of the cutting support mechanism 3, and the processing length of the material strip can be controlled by the moving distance of the bottom end of the pulling mechanism 2, so as to process different types of handles; the long strip of material can be rotated and bent at two points through two provided bending mechanisms 4, so as to transform and process the long strip of material into a U shape, and the bottom end of the pulling mechanism 2 and the cutting support mechanism 4 can be connected to each other. Between the supporting mechanisms 3, the two bending mechanisms 4 move in opposite directions on the base 1, so that the length of the hand-holding part of the handle forming part of the material strip can be adjusted, so as to adapt to the width of the pulling part of different non-woven bags. The opposite moving directions prevent the center position between the two pulling mechanisms 2 from changing, so as to keep the lengths of the two ends of the handle equal during the change and adjustment. The cutting material supporting mechanism 3 is slidably installed on the base 1, so that the cutting material supporting mechanism 3 can move when supporting different material strip widths, so that the axis of the material strip always corresponds to the center between the bending parts of the bending mechanism 4, avoiding the occurrence of asymmetry at the two ends of the handle after bending.

[0042] In any of the above embodiments, Figure 1-5 As shown, the transmission rods 5 are rotatably installed on the opposite side walls of the two bending mechanisms 4, and the two transmission rods 5 are rotatably connected.

[0043] In this embodiment, through the relative rotation of the two transmission rods 5 and the front-to-rear sliding connection between the guide slide seats 6, the two bending mechanisms 4 can move to the same length when the horizontal movement directions are opposite, so that when the length of the gripping part of the handle changes, the lengths of the hanging parts at both ends are the same, so as to facilitate the connection with the external bag body, and after the connection, the bag body will not be tilted when a person pulls the bag by hand.

[0044] In any of the above embodiments, Figure 1-5 As shown, the bending mechanism 4 includes: a sliding seat 401, which is slidably installed on the base 1; a clamping cylinder 402, which is installed on the upper surface of the sliding seat 401; a rotating disk 403, which is connected to the moving end of the clamping cylinder 402; wherein the side wall of the sliding seat 401 is rotatably connected to the transmission rod 5.

[0045] In this embodiment, the sliding seat 401 slides on the base 1, so that the material strip thereon changes and adapts when the handle width changes after processing, and moves at equal distances and opposite directions under the drive of the transmission rod 5. The material strip can be adsorbed and driven to rotate by the rotating disk 403 to perform bending operations. The clamping cylinder 402 can make the rotating disk 403 contact the material strip downward so that the rotating disk 403 can form suction after pressing and contacting the material strip to drive it.

[0046] Specifically, the rotating disk 403 is an electric rotating disk, and a suction cup is installed on the lower surface to drive the material strip to be adsorbed after being pressed. The rotation directions of the two rotating disks 403 are opposite.

[0047] Furthermore, a top plate 9 is fixedly mounted on the upper surface of the bottom end of the sliding seat 401, and the support of the top plate 9 at the bottom can lift and support the material strip above to prevent the material strip from sagging downward.

[0048] In any of the above embodiments, Figure 1-5 As shown, a guide hole 4011 is provided on the side wall of the sliding seat 401, the inner wall of the guide hole 4011 is slidably connected to the guide rod 7, the end wall of the guide rod 7 is fixedly installed with a support seat, and the lower surface of the support seat is fixedly connected to the base 1.

[0049] In this embodiment, by setting the guide hole 4011 and the guide rod 7, the directions of the two sliding seats 401 can be accurately reversed horizontally when they move in opposite directions relative to each other, and the position correspondence between the two sliding seats 401 can also be more accurate.

[0050] In any of the above embodiments, Figure 1-5 As shown, a driving cylinder 8 is fixedly installed on the upper surface of the base 1 , and a moving end of the driving cylinder 8 is connected to any sliding seat 401 .

[0051] In this embodiment, the movement of the sliding seat 401 can be more accurate and automatic by driving the air cylinder 8. The moving end of the driving air cylinder 8 drives the sliding seat 401, and under the action of the transmission rod 5, the two sliding seats 401 can move in opposite directions and at the same length relative to each other, which is more accurate in making the lengths of the two ends of the material strip equal after the handle is formed.

[0052] In any of the above embodiments, Figure 1-5As shown, the cutting support mechanism 3 includes: a support plate 301; a clamping seat 302, the inner wall of the clamping seat 302 is slidably connected to the side wall of the support plate 301, and the lower surface of the clamping seat 302 is slidably connected to the base 1; a cutting drive cylinder 303, the cutting drive cylinder 303 is fixed on the upper surface of the clamping seat 302; a cutting tool 304, the cutting tool 304 is respectively fixedly mounted on the moving end of the cutting drive cylinder 303 and the upper surface of the bottom end of the clamping seat 302.

[0053] In this embodiment, the exposed width of the supporting plate 301 is changed through the sliding connection between the supporting plate 301 and the clamping seat 302 so as to adapt to different widths of the material strip. The sliding of the clamping seat 302 can realign the axis of the material strip after adapting to different widths of the material strip so as to perform a bending operation. The cutting drive cylinder 303 controls the cutting tools so that the two cutting tools can shear and break the material strip passing between them so as to continuously process a single section of the material strip.

[0054] Furthermore, an adjusting rod 3031 is fixedly installed on the top of the side wall of the cutting drive cylinder 303, and a fixing rod 3032 is fixedly installed on the upper surface of the clamping seat 302. The top of the fixing rod 3032 is plugged and fixed to the adjusting rod 3031 through an opening, and an interference fit is adopted so that the cutting drive cylinder 303 can be stably plugged and fixed after rotating at different angles.

[0055] Furthermore, the upper surface of the clamping seat 302 is fixed with a cover 3021 by bolts so that the support plate 301 can be pressed after sliding to adjust the exposed width, so that the support plate 301 is stably fixed in the upper position of the clamping seat 302, and the material strip is restricted and guided by the side walls of the support plate 301 and the side walls of the clamping seat 302.

[0056] In any of the above embodiments, Figure 1-5 As shown, the material pulling mechanism 2 includes: a ball screw slide 201; a fixed plate 202, which is respectively installed on the left and right ends of the ball screw slide 201, and the side wall of the fixed plate 202 is fixedly connected to the external wall; a transmission frame 203, which is fixedly connected to the movable end of the ball screw slide 201; a material pulling drive cylinder 204, which is rotatably installed on the side wall of the transmission frame 203; wherein, the lower surface of the movable end of the material pulling drive cylinder 204 cooperates with the upper surface of the bottom end of the transmission frame 203 to clamp and pull the material strip.

[0057] In this embodiment, through the ball screw slide 201 and with the cooperation of the pulling drive cylinder 204, one end of the material strip is clamped and then pulled. The cutting length of the material strip can be selected by selecting the moving length of the moving end of the ball screw slide 201, so as to process the handle size required for different bag bodies.

[0058] In any of the above embodiments, Figure 1-5 As shown, the material pulling mechanism 2 also includes: a clamping block 205, which is rotatably mounted on the moving end of the material pulling driving cylinder 204, and the left side wall of the clamping block 205 is rotatably connected to the side wall of the transmission frame 203.

[0059] In this embodiment, the clamping block 205 is rotatably mounted on the moving end of the material pulling drive cylinder 204 and the side wall of the transmission frame 203 respectively, so that the clamping block 205 can press down and clamp the material strip in a rotating form, so that each rotation and downward clamping of the clamping block 205 is more stable and accurate, avoiding the deviation of the clamping block 205.

[0060] In any of the above embodiments, Figure 1-5 As shown, a groove 206 is respectively formed on the lower surface of the clamping block 205 and the upper surface of the bottom end of the transmission frame 203; and / or an angle 207 is respectively formed on the left side wall of the clamping block 205 and the right side wall of the bottom end of the transmission frame 203.

[0061] In this embodiment, the lower surface of the clamping block 205 and the upper surface of the bottom end of the transmission frame 203 are made uneven by the groove 206, so as to prevent the material strip from sliding when the material strip is pulled, making the clamping transmission more stable and preventing the material strip from loosening;

[0062] The beveled angle 207 provided can provide a longitudinal clamping force on the material strip, so that the material strip can be clamped and fixed more firmly when the material strip is moved.

[0063] In any of the above embodiments, Figure 1-5 As shown, a support hole 2031 is provided at the upper end of the side wall of the transmission frame 203 , the inner wall of the support hole 2031 is slidably connected to the support rod 208 , and the end walls of the support rod 208 are respectively fixedly connected to the side walls of the fixing plate 202 .

[0064] In this embodiment, through the sliding connection and support of the support hole 2031 and the support rod 208, the left and right movement of the transmission frame 203 is more stable, avoiding shaking and deviation, making the material belt more precise during pulling and docking, and reducing errors during processing.

[0065] Workflow: The material pulling mechanism 2 is responsible for pulling and transporting the material strip, after which the cutting support mechanism 3 is responsible for flattening and cutting, and finally the bending mechanism 4 is responsible for bending and forming the material strip;

[0066] The ball screw slide 201 drives the transmission frame 203 to the right end to dock the material strip on the cutting support structure 3, and drives the clamping block 205 to clamp and fix it through the material pulling drive cylinder 204. After the material pulling mechanism 2 pulls the material, it sends an action signal. The two cutting tools 304 cut and break the material strip through the material cutting drive cylinder 303. The clamping cylinder 402 moves downward, and after pressing the material strip, the drive cylinder 8 pushes the sliding seat 6, driving the transmission rod 5 to shrink inward at the same time. The transmission rod 5 and the guide slide seat 6 drive the two sliding seats 401 to move inward, so that the material strip is arched. At the same time, the two rotating disks 403 drive the two ends of the material strip and rotate in opposite directions. Make the material strip into a "U" shape. After the molding is completed, the drive cylinder 10 pushes back to drive the transmission rod 5 to stretch outward, and the various mechanism components are reset. In this process, the transmission rod 5 can adjust the length of the extension, and then adjust the angle of the material strip arching. The two ends of the bent material strip are aligned with the conveying line of the external bag body for hot pressing and fixing.
