DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The core of the present invention is to provide a wire feeding device, which can be independently arranged relative to the bundling machine to avoid occupying the space of the bundling machine, and can be connected to a larger wire supply reel to achieve long-term continuous wire feeding and avoid frequent replacement of the wire supply reel.

[0039] Another core of the present invention is to provide a bundling machine including the above-mentioned wire feeding device.

[0040] Please refer to Figures 1 to 3 , Figure 1 A schematic structural diagram of a specific embodiment of the wire feeding device provided by the present invention; Figure 2 for Figure 1 A schematic diagram of the wire feeding device in the wire feeding state; Figure 3 for Figure 1 Schematic diagram of the wire feeding device in the wire feeding state. Figure 2The wire feeding state refers to the moving wheel assembly moving in a direction away from the first guide and clamping assembly and the second guide and clamping assembly until the filamentary product is pulled out from the wire supply reel to a position of a suitable length; Figure 3 The wire feeding state refers to the moving wheel assembly moving toward the direction close to the first guide clamping assembly and the second guide clamping assembly until the filamentary product is output to the strapping machine at a position of a suitable length.

[0041] This specific embodiment provides a wire feeding device, comprising: a first wire guide tube 1, a first guide and clamping assembly, a moving wheel assembly, a second guide and clamping assembly, and a second wire guide tube 26, which are sequentially arranged in the transverse direction;

[0042] The filamentary product 25 can be inserted through the first wire guide tube 1, and pass through the first guide and clamping assembly, the moving wheel assembly, the second guide and clamping assembly, and the second wire guide tube 26 in sequence; the first guide and clamping assembly and the second guide and clamping assembly can both clamp or loosen the filamentary product 25 inserted therein;

[0043] The moving wheel assembly is movably arranged in the vertical direction.

[0044] It should be noted that the first wire guide tube 1 and the second wire guide tube 26 can be configured to have smooth edge structures to avoid abrasion of the filamentary product 25 during the wire feeding process.

[0045] The first guide and clamping assembly and the second guide and clamping assembly can be located at the same height or at different heights. During the vertical movement of the moving wheel assembly, the moving wheel assembly will have a moving component perpendicular to the conveying direction of the filamentary product 25 so as to pull the filamentary product 25 out of the wire supply reel. The moving component perpendicular to the conveying direction of the filamentary product 25 mentioned here means that the moving direction of the moving wheel assembly is perpendicular to the connecting direction of the first guide and clamping assembly and the second guide and clamping assembly, or the moving direction of the moving wheel assembly has a component perpendicular to the connecting direction of the first guide and clamping assembly and the second guide and clamping assembly.

[0046] The first wire guide tube 1 is fixedly installed on the left wire guide tube fixing plate 1-1, and the second wire guide tube 26 is fixedly installed on the right wire guide tube fixing plate 1-1. The wire guide tube fixing plate 1-1 can be fixedly connected to the installation base for installing the first guide clamping assembly and the second guide clamping assembly.

[0047] The first guide and clamping assembly and the second guide and clamping assembly can both guide the filamentary product 25 that penetrates therein, and clamp or release the filamentary product 25 that penetrates therein. When the first guide and clamping assembly is in a loose state and the second guide and clamping assembly is in a clamping state, the moving wheel assembly is moved away from the first guide and clamping assembly and the second guide and clamping assembly, so that the filamentary product 25 can be pulled out from the wire supply reel. When the first guide and clamping assembly is in a clamping state and the second guide and clamping assembly is in a loose state, the moving wheel assembly is moved toward the first guide and clamping assembly and the second guide and clamping assembly, and the equipment used in conjunction with the wire feeding device is actuated, so that the filamentary product 25 can be pulled out from the second wire guide tube 26.

[0048] The number of the moving wheel groups in the moving wheel assembly needs to be determined according to the actual situation, and can be one group, or two groups or more groups, specifically determined according to the actual situation. When there is only one group of moving wheel groups, the filamentous product 25 passes through the first guide and clamping assembly, the moving wheel group and the second guide and clamping assembly in sequence.

[0049] In the process of using the wire feeding device provided by this specific embodiment, the filamentary product 25 of the wire supply disk needs to be firstly passed through the first wire guide tube 1, and then passed through the first guide and clamping assembly, the moving wheel assembly and the second guide and clamping assembly in sequence, and passed through the second wire guide tube 26. After passing through, the filamentary product 25 can be directly connected to the bundling machine. Then the second guide and clamping assembly is made to clamp the filamentary product 25, and the moving wheel assembly is controlled to move in a direction away from the first guide and clamping assembly and the second guide and clamping assembly, so that the filamentary product 25 between the first guide and clamping assembly and the moving wheel assembly and between the second guide and clamping assembly and the moving wheel assembly is stretched, so that the filamentary product 25 is pulled out of the wire supply disk; then the first guide and clamping assembly is controlled to clamp the filamentary product 25, the second guide and clamping assembly is controlled to release the filamentary product 25, and the moving wheel assembly is controlled to move in a direction close to the first guide and clamping assembly and the second guide and clamping assembly. In this process, the bundling machine is activated to complete the bundling; repeating the above steps can realize the continuous wire feeding process of the filamentary product 25.

[0050] Compared with the prior art, the wire feeding device provided in this specific embodiment is independently arranged and does not need to be installed on the bundling machine. Therefore, it is not limited by the size of the bundling machine and can be connected to a larger wire supply reel to achieve a long-term continuous wire feeding process, avoiding the operation of frequent replacement of the wire supply reel; and can realize the automation of the wire feeding process, reduce human participation, and reduce labor costs.

[0054] When it is necessary to pull the filamentary product 25 out of the wire supply disk, the third wire feeding idler wheel 7 needs to cooperate with the second wire pressing wheel 9 to press the filamentary product 25 passing through the third wire feeding idler wheel 7 and the second wire pressing wheel 9, and the second wire feeding idler wheel 4 needs to cooperate with the first wire pressing wheel 5 to loosen the filamentary product 25 passing through the second wire feeding idler wheel 4 and the first wire pressing wheel 5, and control the moving wheel assembly to move in the direction away from the first guide clamping assembly and the second guide clamping assembly; when it is necessary to transport the filamentary product 25 from the wire feeding device to the bundling machine, the third wire feeding idler wheel 7 needs to cooperate with the second wire pressing wheel 9 to loosen the filamentary product 25 passing through the third wire feeding idler wheel 7 and the second wire pressing wheel 9, and the second wire feeding idler wheel 4 needs to cooperate with the first wire pressing wheel 5 to compact the filamentary product 25 passing through the second wire feeding idler wheel 4 and the first wire pressing wheel 5; and control the moving wheel assembly to move in the direction close to the first guide clamping assembly and the second guide clamping assembly.

[0055] The first guide and clamping assembly may further include a first wire feed idler wheel 2 and a first cam 3 tangentially arranged with the first wire feed idler wheel 2, wherein the first wire feed idler wheel 2 and the first cam 3 are both rotatably arranged on the first mounting plate 6;

[0058] Preferably, the first power component and the second power component can both be set as wire pressing cylinders 12, the wire pressing cylinders 12 are fixedly arranged on the wire pressing cylinder fixing plate 13, and the two groups of wire pressing cylinders 12 are symmetrically arranged about the middle section of the wire feeding device. Of course, the first power component and the second power component can also be other power-providing components such as motors, electric cylinders, and motors, which are determined according to actual conditions.

[0059] The first wire pressing wheel 5 and the second wire pressing wheel 9 can be connected to the corresponding sliding structure, and when the wire pressing cylinder 12 is extended or retracted, the first wire pressing wheel 5 or the second wire pressing wheel 9 can be driven to slide along the sliding structure. The sliding structure can be a guide rail slider assembly or a slide groove structure, which is determined according to actual conditions.

[0060] Although the wheel group composed of the first wire feed idler 2 and the first cam 3, the wheel group composed of the fourth wire feed idler 8 and the second cam 10, and the wheel group composed of the fifth wire feed idler 16-1 and the third cam 16-2 can all play a certain guiding effect, in order to make the wheel group composed of the first wire feed idler 2 and the first cam 3, the wheel group composed of the fourth wire feed idler 8 and the second cam 10, and the wheel group composed of the fifth wire feed idler 16-1 and the third cam 16-2 play a better guiding effect, annular grooves can be provided on the outer circumferences of the first wire feed idler 2, the fourth wire feed idler 8 and the fifth wire feed idler 16-1 to prevent the filamentary product 25 from running off; during use, each cam is arranged to fit and tangent to the corresponding wire feed idler, and the filamentary product 25 is located in the annular groove.

[0061] The cams mentioned in the present application document include a first cam 3, a second cam 10 and a third cam 16-2, and the wire feed idler wheels include a first wire feed idler wheel 2, a second wire feed idler wheel 4, a third wire feed idler wheel 7, a fourth wire feed idler wheel 8 and a fifth wire feed idler wheel 16-1.

[0062] Preferably, the first guide clamping assembly and the second guide clamping assembly can be symmetrically arranged about the middle cross-section of the wire feeding device so that the first guide clamping assembly and the second guide clamping assembly are located at the same height to facilitate processing and assembly.

[0063] like Figure 2 and Figure 3 As shown, the filamentary product 25 passes through the first wire guide tube 1 on the left and passes through the second wire guide tube 26 on the right. During use, due to Figure 2 and Figure 3The wire feeding device shown is a symmetrical structure about the middle cross section, so the filamentary product 25 can also be passed through the second wire guide tube 26 on the right and passed out of the first wire guide tube 1 on the left, which is determined according to actual conditions.

[0064] On the basis of the above embodiment, the moving wheel assembly can include a moving wheel group, a lifting component and a push-pull plate 17 on which the moving wheel group is installed; the lifting component is connected to the push-pull plate 17 and drives the push-pull plate 17 to move up and down, so that the moving wheel group is relatively close to or away from the first guide clamping assembly and the second guide clamping assembly.

[0065] The lifting component includes a power piece, a fixed slide rail 21 and a slider 22 slidably arranged relative to the slide rail 21 . The push-pull plate 17 is connected to the slider 22 , and the output end of the power piece is connected to the push-pull plate 17 .

[0066] The power part can be a push-pull cylinder 18, which is installed on a push-pull cylinder fixing plate 19; the telescopic end of the push-pull cylinder 18 is connected to the push-pull plate 17 to drive the push-pull plate 17 to move up and down, so that the moving wheel group is close to or away from the first guide clamping assembly and the second guide clamping assembly.

[0067] When the number of moving wheel groups is one group, the moving wheel group can be set on the midline of the connecting line of the first guide and clamping assembly and the second guide and clamping assembly. After the filamentary product 25 passes through the first guide and clamping assembly, it passes through the moving wheel group and then passes into the second guide and clamping assembly.

[0068] It should be noted that the moving wheel group can be arranged on the upper part of the first guide clamping assembly and the second guide clamping assembly, or can be arranged on the lower part of the first guide clamping assembly and the second guide clamping assembly, which is determined according to the actual situation; Figure 1 As shown, the moving wheel set is arranged at the lower part of the first guide clamping assembly and the second guide clamping assembly, and is driven to approach or move away from the first guide clamping assembly and the second guide clamping assembly by the push-pull cylinder 18.

[0071] Compared with not setting the fixed wheel group 16, setting the fixed wheel group 16 can make the movable wheel group move in the direction away from the first guide clamping assembly and the second guide clamping assembly. Under the condition of the same moving distance, the wire supply reel can pull out a longer filamentary product 25 than that without the fixed wheel group 16; when the length of the filamentary product 25 required by the tying machine at a time remains unchanged, the moving distance of the movable wheel group can be shortened, and the movement of the movable wheel group can be made more stable, and the filamentary product 25 can be prevented from oscillating.

[0072] Preferably, the fixed wheel set 16 can be installed on the push-pull cylinder fixed plate 19 through the fixed wheel set connecting plate 20.

[0075] The push-pull cylinder 18 can drive the push-pull plate 17 to slide downward until the push-pull plate 17 contacts the limit adjustment piece 24. Therefore, by adjusting the installation position of the limit adjustment piece 24, the sliding range of the push-pull plate 17 can be adjusted to adjust the length of the filamentary product 25 tensioned during a single movement of the moving wheel assembly; the limit adjustment piece 24 can be set as a plate-like structure, and a waist-shaped hole can be set in the plate-like structure, and a threaded hole can be set in the push-pull cylinder fixing plate 19, and the position of the waist-shaped hole relative to the threaded hole can be adjusted, and the installation position of the limit adjustment piece 24 can be adjusted; or multiple groups of threaded holes can be set along the moving direction of the moving wheel assembly, which is determined according to actual conditions.
