Technical Field

[0001] The invention relates to rubber band processing equipment, in particular to a rubber band splicing machine. Background Art

[0002] In the traditional manufacturing process, long strips of elastic bands are sewn together into circular elastic rings, usually by hand.

[0003] In the manual sewing process, the long elastic band is folded manually, the two ends of the elastic band are overlapped or pressed together, and the elastic band with the two ends in the overlapping or pressed together state is sewed by a sewing machine.

[0004] The above manual sewing process has complicated operation steps, requires high operator proficiency, and has low processing efficiency. Summary of the invention

[0005] In view of this, an object of the present invention is to provide a rubber band splicing machine, which can automatically sew the ends of rubber bands and has high processing efficiency.

[0006] In order to solve the above technical problems, the technical solution of the present invention is:

[0007] A rubber band joining machine, comprising a frame, a sewing machine body is mounted on the frame, the sewing machine body comprises a sewing platform and a sewing joint, the sewing joint is used to sew the rubber band on the sewing platform, and the frame is provided with a material clamping mechanism, a material turning mechanism, and a material cutting mechanism;

[0008] The turning mechanism is located below the seaming platform, and includes a mounting platform, on which two clamping claws are mounted, and the two clamping claws are symmetrically distributed on the left and right sides of the seaming platform, and a rotating driving part corresponding to the clamping claws is provided on the mounting platform, and the rotating driving part is used to drive the clamping claws to flip to the top or bottom of the seaming platform, and a sliding driving part is provided on the frame, and the sliding driving part is used to drive the mounting platform to move, and the clamping claws on the mounting platform can move closer to or away from the seam joint;

[0009] The material clamping mechanism and the material cutting mechanism are respectively located on the left and right sides of the material turning mechanism. The material clamping mechanism is used to clamp the rubber band in the material cutting mechanism and pull it into the material turning mechanism. The material cutting mechanism is used to cut the rubber band.

[0010] Through the above technical scheme, the rotating driving part drives the clamping claw to be located below the sewing platform, the elastic band will be located on the cutting mechanism first, the clamping mechanism will clamp the end of the elastic band in the cutting mechanism, and the clamping mechanism will drag the elastic band to the clamping claw of the turning mechanism, the cutting mechanism cuts the elastic band, the two clamping claws clamp the two ends of the elastic band respectively, the rotating driving part drives the clamping claw to flip to above the sewing platform, the two ends of the elastic band approach each other, the sliding driving part drives the mounting platform to move toward the seaming joint, the seaming joint can automatically sew the end of the elastic band clamped on the clamping claw, and after the sewing is completed, the clamping claw can also push the sewn elastic band off the sewing platform;

[0011] The above-mentioned automated sewing operation completes the actions of automatic clamping, cutting, sewing and unloading. Not only is the overall sewing processing efficiency high, but also because the clamping claws and the sliding drive unit cooperate with each other to complete the clamping and pushing of the rubber band, the pushing mechanism for pushing the rubber band is eliminated, the feeding stroke is short, and the structure is highly compact.

[0012] Preferably, a pushing portion is provided on the seaming platform, and the pushing portion includes a pushing plate and a pushing drive assembly, and the pushing drive assembly is used to drive the pushing plate to move along the plane where the seaming platform is located, and the end of the pushing plate close to the seam joint is the pushing end, and the pushing end is used to abut against the end of the elastic band to be sewn and make the end of the elastic band flush.

[0013] Through the above technical scheme, when the rotating drive unit drives the clamping claw holding the end of the elastic band to flip to above the sewing platform, the end of the elastic band is also located on the upper plate surface of the pushing plate, and the sliding drive unit drives the mounting platform to move toward the seam joint. When the elastic band is located below the sewing head, the pushing drive assembly can drive the pushing plate to move toward the sewing head, and the end surface of the pushing end of the pushing plate can be aligned with the two end surfaces of the elastic band, thereby making the two end surfaces of the elastic band flush, and the seam joint then sews the two end surfaces of the elastic band, and the seam joints formed on the elastic band are more neat and the seam firmness is higher.

[0014] Preferably, the left and right sides of the pushing plate are respectively provided with inclined surfaces corresponding to the clamping claws one by one.

[0015] Through the above technical solution, when the rotating drive unit drives the clamping claw holding the end of the rubber band to flip to above the seaming platform, the end of the rubber band will contact the inclined surface of the pushing plate, which is beneficial to increase the effective contact area between the rubber band and the pushing plate, thereby reducing the probability of wrinkles generated by the rubber band during the movement process, and ensuring the overall processing quality in the later stage.

[0016] Preferably, a seam groove is provided on the upper surface of the seam platform, the seam groove is located below the seam joint, and a protrusion extending into the seam groove is provided on the pushing end.

[0017] Through the above technical solution, the unstitched elastic band can move along the upper surface of the seam platform provided with the seam groove. When the pushing plate moves, the protrusion at the pushing end will move along the seam groove, thereby improving the contact stability between the pushing end and the end of the elastic band, and the alignment accuracy of the end of the elastic band is higher.

[0018] Preferably, the seam joint includes a seam presser foot, and the seam presser foot is used to press the elastic band onto the seam platform.

[0019] Through the above technical solution, the clamping jaws move the elastic band to the position below the sewing head, the sewing presser foot takes over the clamping jaws and presses the two ends of the elastic band, and the sewing head performs sewing processing on the elastic band at this position. At the same time, the rotating drive unit and the sliding drive unit both reset the clamping jaws, and the clamping jaws clamp and transport the next elastic band to be sewn.

[0020] When the first elastic band is sewn, the sewing presser foot releases the pressing effect on the elastic band, and the clamping claw clamps the next elastic band to be sewn and pushes the first elastic band that has been sewn away from the sewing platform;

[0021] In the above processing flow, the time required for sewing the first elastic band is fully utilized to transfer the second elastic band to be sewn, and the overall automated processing efficiency is further improved.

[0022] Preferably, it further comprises a material receiving mechanism located at one side of the seaming platform, wherein the material receiving mechanism comprises a material receiving frame, and a material receiving rod is installed on the material receiving frame.

[0023] Through the above technical solution, the stitched elastic band can be pushed away from the stitching platform by the clamping claws, and the elastic platform after stitching will fall to the material receiving mechanism, and the material receiving rod can pass through the stitched elastic band to realize automatic material receiving action.

[0024] Preferably, a material receiving tray and a material receiving drive motor for driving the material receiving tray to rotate are installed on the material receiving rack, the number of the material receiving rods is more than two, and all the material receiving rods are distributed on the material receiving tray along the circumferential direction.

[0025] Through the above technical solution, when a certain number of rubber bands are connected to a single receiving rod, the receiving drive motor can drive the receiving plate to rotate, and other receiving rods can rotate to the receiving position to continue to receive the sewn rubber bands.

[0026] Preferably, at least two air pipes are further included, and the air pipes are distributed on the left and right sides of the seaming platform. The air pipes are provided with air outlets, and the air outlets face the upper surface of the seaming platform.

[0027] Through the above technical solution, when the rotary drive unit drives the clamp holding the end of the rubber band to flip to above the seaming platform, the gas in the air pipe will be ejected from the air outlet, and this part of the gas will blow toward the end of the rubber band, reducing the upward warping of the rubber band.

[0028] Preferably, it further comprises a cutting drive unit, the cutting mechanism comprises a cutting table and a cutting knife group installed on the cutting table, and the cutting drive unit is used to drive the cutting mechanism to move towards or away from the side of the turning mechanism.

[0029] Through the above technical solution, on the one hand, since the turning mechanism adopts a rotating structure of the clamping claw, the cutting mechanism can be driven by the cutting drive unit to move back and forth, thereby avoiding interference between the turning mechanism and the cutting mechanism, which helps to improve the structural compactness between the two; on the other hand, in the process of cutting the rubber band, in addition to the cutting action of the cutting knife group, the cutting mechanism can also be used to move closer to or away from the turning mechanism to improve the cutting ability of the material.

[0030] Preferably, it also includes a connecting piece, which is located between the cutting mechanism and the turning mechanism, and the connecting piece includes a connecting drive part and a connecting table. The connecting drive part is installed on the side of the cutting table, and the upper surface of the connecting table is used to contact with the rubber band, and the connecting drive part is used to drive the connecting table to move up and down.

[0031] Through the above technical scheme, on the one hand, based on the special material of the rubber band, when the rubber band is clamped and pulled between the two chucks by the clamping mechanism, part of the rubber band will still span between the single chuck and the cutting mechanism. At this time, the connecting drive part drives the connecting table to rise, and the connecting table can drag the rubber band between the chuck and the cutting mechanism to prevent the rubber band between the chuck and the cutting mechanism from sagging and making the cut rubber band too long; on the other hand, the connecting table can help to improve the flatness of the rubber band on the cutting knife group, and the cutting knife group can more easily cut the rubber band.

[0032] The technical effects of the present invention are mainly reflected in:

[0033] (1) The clamping mechanism, turning mechanism, cutting mechanism and receiving mechanism are automatically connected to each other to complete the automatic sewing and unloading of the rubber band, with high processing efficiency;

[0034] (2) The focus is on improving the turning mechanism. The clamp is installed below the sewing platform. By turning the clamp and driving the sliding drive unit, the two ends of the rubber band can be automatically spliced. The rubber band after sewing can be unloaded on the original sewing platform, realizing short-distance automatic unloading. It fully utilizes the original clamp action, and no additional pushing mechanism is set in the middle. The structure is highly compact and the feeding stroke is short.
