[0035] Embodiment 1:

[0036] The following is combined with Figure 1-6 This application is described in further detail.

[0037] The present application embodiment discloses a double-station automatic cable tie machine, comprising:

[0038] Feeding unit 1, used for unidirectionally conveying a fixed amount of materials to be bundled in batches;

[0039] Two strapping machines 2 are provided, which are symmetrically arranged on both sides of the rear end of the feeding unit 1, and are used to strap materials, and the table tops of the two strapping machines 2 are flush with the table top of the feeding unit 1;

[0040] The material dividing unit 3 is arranged above the rear end of the feeding unit 1 and is used to push the materials in the feeding unit 1 into the strapping machines 2 on both sides alternately;

[0041] A transfer unit 4, which is arranged above the strapping machine 2 and is used to transfer the strapped materials;

[0042] A conveyor belt 5, which is transversely arranged on the same side of the two strapping machines 2, and is used to receive the strapped materials removed by the transfer unit 4 and transport them to the next process;

[0043] A support frame 6, which is fixedly mounted on the rear end table of the feeding unit 1 and is used to mount the distributing unit 3 and the transfer unit 4;

[0044] Photoelectric switches 7, which are respectively arranged at the strapping stations of the two strapping machines 2;

[0045] The PLC controller is electrically connected to the feeding unit 1, the strapping machine 2, the material dividing unit 3, the transfer unit 4 and the photoelectric switch 7 respectively, and is used to control each unit to perform step-by-step actions.

[0046] See also Figure 1 and Figure 2 The feeding unit 1 includes a supporting platform 11 and a chain conveyor 12. The chain conveyor 12 is installed inside the supporting platform 11. A plurality of feeding push blocks 13 are fixedly connected to the surface of the chain conveyor 12 at intervals. A through groove 14 is provided on the top surface of the supporting platform 11 along the transmission direction. When the chain conveyor 12 is running, the feeding push blocks 13 can slide along the through groove 14.

[0047] See also Figure 1 and Figure 2 The top surface of the feeding unit 1 is symmetrically and adjustably fixedly connected with feeding limit baffles 15 on both sides of the central axis along its transmission direction. A feeding channel is formed inside the two feeding limit baffles 15, which can limit the two sides of the material during the feeding process and preliminarily tidy up the material during the feeding process. The feeding limit baffle 15 starts from the transmission starting end of the feeding unit 1 and its length does not exceed the vertical projection of the position of the dividing unit 3.

[0048] See also Figure 1 and Figure 2 The top surface of the feeding unit 1 is provided with a material dividing and limiting baffle plate 16 extending toward the strapping machine 2 on both sides along the end of its feeding channel. The material dividing and limiting baffle plates 16 are symmetrically distributed along both sides of the central axis of the strapping machine 2 table, forming a through material dividing channel. The material in the feeding channel enters the material dividing channel on both sides under the drive of the material dividing unit 3.

[0049] See also Figure 1 , Figure 2 and 3 The material distribution unit 3 includes a material distribution synchronous slide 31, a first material distribution cylinder 32 and a second material distribution cylinder 33. The material distribution synchronous slide 31 is horizontally placed between the two strapping machines 2. The first material distribution cylinder 32 and the second material distribution cylinder 33 are fixedly connected to the bottom of the slider of the material distribution synchronous slide 31 side by side. The bottoms of the first material distribution cylinder 32 and the second material distribution cylinder 33 are symmetrically fixedly connected with material distribution push blocks 34. During the pushing process, the two cylinders are alternately extended and retracted. At the same time, under the drive of the reciprocating motion of the material distribution synchronous slide 31, the two material distribution push blocks 34 alternately push the materials into the material distribution channels on both sides until they enter the strapping station of the strapping machine 2.

[0050] See also Figure 1 , Figure 2 and Figure 4The transfer unit 4 includes a transfer synchronous slide 41 and a non-contact suction cup 42. The transfer synchronous slide 41 is horizontally placed between the strapping machine 2 and the conveyor belt 5. The non-contact suction cup 42 is adjustably fixedly connected to the bottom of the slider of the transfer synchronous slide 41 through a connecting rod 43. The reciprocating motion of the transfer synchronous slide 41 drives the non-contact suction cup 42 to and from the strapping station and the conveyor belt 5. The non-contact suction cup 42 can absorb the strapped materials, thereby realizing the transfer of the strapped materials.

[0051] As a further preference of this embodiment, a rotating cylinder 44 is also connected between the bottom end of the connecting rod 43 and the contactless suction cup 42, so as to rotate the bundled materials by 90° during the transfer process.

[0052] As a further preference of this embodiment, it also includes a pressing module 8, which includes a pressing rod 81 and a pressing cylinder 82. The pressing cylinder 82 is fixedly connected to the bottom of the pressing rod 81. The pressing module 8 is arranged above the strapping station of the strapping machine 2, and is used to press and fix one side of the material during strapping.

[0053] As a further preferred embodiment of this embodiment, the photoelectric switch 7 is fixedly installed at the bottom of the holding rod 81 .

[0054] The implementation principle of a double-station automatic cable tie machine in the embodiment of the present application is:

[0055] See also Figure 5 and Figure 6 When in use, a certain amount of stacked materials is placed into the feeding channel from the front end of the transmission unit, and the chain plate conveyor 12 drives the feeding push block 13 to slide along the through slot 14, and then the front end of the feeding push block 13 pushes the materials to move toward the direction of the distributing unit 3;

[0056] The material distribution synchronous slide 31 of the material distribution unit 3 reciprocates above the material distribution channel. During this process, the two material distribution cylinders alternately drive the material distribution push blocks 34 to move downward and contact the platform surfaces on each side. When the material runs along the feeding channel to the material distribution channel, the material is alternately pushed into the material distribution channels on both sides under the drive of the reciprocating motion of the material distribution synchronous slide 31, and during this period, the chain plate conveyor 12 continuously and rhythmically operates.

[0057] When the first material is pushed to the strapping station of the strapping machine 2, the photoelectric switch 7 senses the material below, and the holding cylinder 82 operates, and its piston rod moves downward until it contacts the top of the material, pressing and fixing one side of the material, and the strapping machine 2 performs a strapping action at the same time;

[0058] When the first bundled material is pushed out by the bundled material entering from behind and enters under the non-contact suction cup 42, the non-contact suction cup 42 is started to adsorb it, and then the transfer synchronous slide 41 is operated, and after the bundled material is sent to the top of the conveyor belt 5, the non-contact suction cup 42 is released, and the bundled material falls into the conveyor belt 5, and then is transported to the next process by the conveyor belt 5;

[0059] Repeat the above actions, and the strapping action and transfer action on both sides will run alternately to realize the double-station automatic strapping of materials.

[0060] It should be noted that the above-mentioned synchronous interval actions can be realized through PLC program control, and the control principles and electrical connection methods involved are existing technologies well known to those skilled in the art, so they will not be repeated in this application.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
