Description

TECHNICAL FIELD

[0001] The present application belongs to the field of baling press equipment, more particularly, relates to a wire feeding mechanism and a reinforcing bar baling press using the same. BACKGROUND

[0002] In the traditional industry, the reinforcing bars, steel bars and the like are usually baled by manual work with simple tools. Under the manual labor condition, the workers are prone to fatigue due to the high work intensity, and the work injury is likely to occur, which is not conducive to the safety production. Meanwhile, the baling efficiency is low and the baling quality is not high. In order to solve these problems, some reinforcing bar baling equipment appears in the market, such as the Chinese invention patent "Rod baling press and baling method" (application number CN2010105702801, application date December 2, 2010, authorization announcement date August 15, 2012), but these equipment has the following problems: (1) the gripping force of the baling wire is not enough, so that the baling tightness is not enough, resulting in loose baling; (2) the baling wire is prone to winding and rolling when feeding; (3) the baling wire lacks the related design of automatic feeding.

[0003] In order to overcome the problems of the traditional industry and the existing reinforcing bar baling machine, the relevant cooperative company has developed the Chinese invention patents "Full-automatic mechanical hand reinforcing bar baling machine" (application number 2015103507968, application date June 23, 2015, authorization announcement date December 26, 2017) and "Reinforcing bar baling machine based on driven opening and closing clamping block device" (application number 2016102833451, application date April 28, 2016, authorization announcement date May 11, 2018).

[0004] The Chinese invention patent with the announcement number CN104925293B discloses a reinforcing bar baling equipment named "Full-automatic mechanical hand reinforcing bar baling machine". The invention patent realizes the baling of the reinforcing bar bundle by the cooperation of the down wire feeding straightening workbench and the rotating clamping mechanical paw. The down wire feeding straightening workbench is composed of a base, a disorderly wire frame, a roller straightening machine, a hydraulic shear, an opening and closing guide pipe and a stand. The opening and closing guide pipe is composed of a jacking hydraulic cylinder, a four-bar linkage mechanism and a guide pipe (the jacking hydraulic cylinder can control the opening and closing state of the guide pipe through the four-bar linkage mechanism). During the work, the down wire feeding straightening workbench is responsible for feeding the baling wire through the bottom of the reinforcing bar bundle and into the rotating clamping mechanical paw (at this time, the opening and closing guide pipe of the down wire feeding straightening workbench is in the closed state, the wire is fed into the opening and closing guide pipe, and the opening and closing guide pipe plays the role of wire feeding guide). When the wire feeding length reaches the set wire feeding length, the hydraulic shear cuts off the wire, then the opening and closing guide pipe is opened, and the rotating clamping mechanical paw pulls the two ends of the wire to the set height and then rotates, realizing the baling of the reinforcing bar bundle.

[0005] A Chinese invention patent with publication number CN105775201B discloses a steel bar bundling machine based on a driven opening and closing clamp block device. The driven opening and closing clamp block device is used to replace the opening and closing guide pipe in the patent with publication number CN104925293B. Compared with the opening and closing guide pipe in the patent with publication number CN104925293B, the driven opening and closing clamp block device has a simple structure and does not need a hydraulic cylinder or a pneumatic cylinder as a driving component, thereby simplifying the movement mechanism and saving cost. Meanwhile, the control program of the hydraulic cylinder or the pneumatic cylinder is omitted, and malfunction is effectively avoided.

[0006] Although these bundling machines not only solve the above problems but also are favored by the market, the above steel bar bundling machine can only realize the threading, bundling and rotation of one bundling steel bar in actual use, i.e. for the steel bar to be bundled, only one steel bar can be used for bundling (for a fixed bundling position, only one steel bar can be used for bundling), and the bundling of multiple steel bars cannot be realized (i.e. for a fixed bundling position, multiple steel bars cannot be used for bundling). Although the bundling effect of the bundling machine is good, the bundling with one steel bar can also meet the needs of customers, but in some conditions, two steel bars must be used for bundling to meet the transportation and use requirements, which seriously limits the application of the steel bar bundling machine, and the bundling machine cannot be popularized and used. In addition, the front and rear pushing feeding mode needs to accurately control the feeding process of the bundling steel bar, and is prone to cause poor feeding or errors. SUMMARY

[0026] The technical solutions of the present application will be further described below through specific examples.

[0027] The following will be described by taking the improved "steel bar bundling machine with top wire inlet" of the relevant cooperative company as an example. As shown in the accompanying drawings Figure 1 A steel bar bundling machine is shown in Chinese utility model patent "steel bar bundling machine with top wire inlet", (patent number ZL2021206564094, application date March 31, 2021, authorization announcement date February 1, 2022), among which the screwing mechanical hand adopts the structure of the invention patent "mechanical hand for screwing and bundling" (patent number ZL2015103514162, application date June 23, 2015, authorization announcement date December 26, 2017), the opening and closing guide pipe adopts the structure of the utility model patent "driven opening and closing clamping block device for wire threading guide applied to steel bar bundling machine" (patent number ZL2016203827699, application date April 28, 2016, authorization announcement date November 23, 2016) or the structure of the utility model patent "automatic opening and closing guide pipe device based on spring sheet" (patent number ZL2020217655389, application date August 21, 2020, authorization announcement date April 6, 2021). No matter which structure of the opening and closing guide pipe is adopted, a plurality of opening and closing guide pipes need to be arranged in the wire inlet direction to form a basically continuous wire feeding channel, so that the steel bar for bundling enters the horizontally arranged wire feeding channel after entering the rear end of the bundling machine and passing through the straightening, and then enters the through hole of the left and right clamping working surfaces of the left and right rotating arms. For the convenience of description, the entire wire feeding channel is divided into two components, the section from the screwing mechanical hand to the hydraulic shear is called "outer wire feeding channel", and the section between the left and right rotating arms of the screwing mechanical hand is called "inner wire feeding channel". In order to solve the problem of bundling of stacked profile steel bars or steel pipes, a lifting mechanism is arranged between the opening and closing guide pipes in the inner wire feeding channel, which is specifically described in Chinese utility model patent application "lifting mechanism and steel bar bundling machine using the same" (application date December 17, 2022, application number 2022233889558) or invention patent application "lifting mechanism and steel bar bundling machine using the same" (application date December 17, 2022, application number 202211627837X).

[0028] As Figure 2The basic working process of the tying machine is illustrated by taking the tying of the bar steel as an example. Since the cross section of the steel is circular or approximately circular, the steel to be tied is gathered into a bundle, and the cross section of the tied steel is circular or approximately circular. The tying steel passes through the bundle of steel from below, and the left and right ends of the tying steel are arranged in the through holes of the left clamping working surface below the left rotating arm and the right clamping working surface below the right rotating arm, respectively. During the tying process, the left rotating arm and the right rotating arm move upward, thereby driving the tying steel to move along the left and right ends of the steel to be tied. Since the steel to be tied is gathered into a bundle, and the cross section of the tied steel is circular or approximately circular, the tying steel has small resistance to the steel to be tied, and the tying steel can be in good contact (i.e., close fit) with the bundle of steel (i.e., the steel to be tied), especially with the bottom or lower surface of the bundle of steel. At this time, above the tying steel, the left and right clamping arms drive the left and right clamping working surfaces to clamp and rotate the tying steel into a knot, thereby tying and bundling the bundle of steel. In the delivery channel composed of the opening and closing guide pipes, the front and rear tying steels are delivered by the front and rear pushing method, i.e., after being cut by the hydraulic shear, the tail of the front steel is pushed by the head of the rear steel to move forward along the delivery channel. For the steel to be tied, there is only one tying steel at the fixed tying position to achieve the tying, and it is impossible to achieve the tying of multiple steels.

[0029] In the present application, the "outer delivery channel" is replaced as a whole, i.e., the delivery mechanism of the present application is installed and used as an "outer delivery channel". As shown in FIG. 1, the delivery mechanism of the present application is installed and used as an "outer delivery channel". Figure 3As shown, the two open-close pipes constitute an "inner wire feeding channel", and a jacking mechanism (not shown in the figure) is optionally arranged between the two open-close pipes. The first fixed part and the second fixed part of the wire feeding mechanism are arranged between the inner wire feeding channel and the hydraulic shears, and the first fixed part and the second fixed part are both arranged in parallel along the wire feeding direction of the reinforcing steel bars for bundling. A first moving part that can move along the wire feeding direction of the reinforcing steel bars for bundling is arranged on the first fixed part. The first fixed part is a rail screw, and the first moving part is a slider that moves on the rail screw. A servo motor or a hydraulic motor is used as a power source and is controlled. A wire feeding groove is arranged in the second fixed part, which is matched with the inner wire feeding channel (i.e., the open-close pipes and the wire feeding channel of the open-close pipes) and the hydraulic shears in the reinforcing steel bar bundling machine, so that the reinforcing steel bars for bundling can be fed along the path of "hydraulic shears-wire feeding groove-open-close pipes". The second moving part is connected to the first moving part at one end (i.e., the top) and is arranged in the wire feeding groove of the second fixed part at the other end (i.e., the bottom). When the first moving part moves on the rail screw, the first moving part drives the second moving part connected thereto to also move along the wire feeding direction. The other end of the second moving part in the wire feeding groove also moves along the wire feeding direction, thereby pushing one or two reinforcing steel bars for bundling in the wire feeding groove towards the open-close pipes and the wire feeding channel of the open-close pipes. Of course, according to the wire feeding requirement of one or multiple reinforcing steel bars for bundling, the wire feeding channel of the open-close pipes is expanded in the diameter direction based on the original application of a single reinforcing steel bar for bundling to meet the requirement. As shown in FIGS. 1-3, the wire feeding mechanism is arranged in the reinforcing steel bar bundling machine, and the wire feeding mechanism is arranged between the inner wire feeding channel and the hydraulic shears. The wire feeding mechanism is arranged in the reinforcing steel bar bundling machine, and the wire feeding mechanism is arranged between the inner wire feeding channel and the hydraulic shears. Figure 4 As shown in FIG. 4, the cross section of the second fixed part is observed along the wire feeding direction. It can be seen that the wire feeding groove is arranged at the central position of the second fixed part. The top of the second moving part is fixedly connected to the first moving part, and the bottom of the second moving part is arranged in the wire feeding groove of the second fixed part to push the reinforcing steel bars for bundling. At this time, two reinforcing steel bars for bundling are arranged in the wire feeding groove, thereby providing two reinforcing steel bars for bundling for a specific bundling position to realize the subsequent clamping and rotating bundling action.

[0030] As shown in FIGS. 1-3, the wire feeding mechanism is arranged in the reinforcing steel bar bundling machine, and the wire feeding mechanism is arranged between the inner wire feeding channel and the hydraulic shears. The wire feeding mechanism is arranged in the reinforcing steel bar bundling machine, and the wire feeding mechanism is arranged between the inner wire feeding channel and the hydraulic shears. Figure 5 and 6 As shown in FIGS. 1-3, the wire feeding mechanism is arranged in the reinforcing steel bar bundling machine, and the wire feeding mechanism is arranged between the inner wire feeding channel and the hydraulic shears. The wire feeding mechanism is arranged in the reinforcing steel bar bundling machine, and the wire feeding mechanism is arranged between the inner wire feeding channel and the hydraulic shears. Figure 5 is a view observed along the wire feeding direction, Figure 6 is a side cross-sectional view, and the two are combined to explain as follows:

[0031] From Figure 4 and 5The second moving part includes a horizontal part 26-1, a vertical part 26-2 and a protruding part 26-3. The horizontal part constitutes the top of the second moving part. One end of the horizontal part is fixedly connected with the first moving part, so that the second moving part and the first moving part are connected as a whole. A first connecting hole 26-4 is arranged at the one end of the horizontal part, and the two are fixedly connected by a screw or a bolt. The horizontal part has a certain length, one end of which is fixedly connected with the first moving part, and the other end extends above the wire feeding groove of the second fixed part. The vertical part is arranged in a vertical downward direction which is substantially perpendicular to the horizontal part. The bottom of the vertical part is provided with the protruding part. The protruding part constitutes the bottom of the second moving part. The shapes of the vertical part and / or the protruding part are matched with the shape of the wire feeding groove of the second fixed part. When the first moving part moves on the first fixed part, the first moving part drives the second moving part to move as a whole. At this time, the vertical part and / or the protruding part can move in the wire feeding groove of the second fixed part and push the reinforcing steel bars in the wire feeding groove to move in the inward wire feeding channel. A wire feeding hole 26-5 is arranged on the vertical part of the second moving part and matched with the hydraulic shear. In the wire feeding process, after the reinforcing steel bars pass through the hydraulic shear, they enter the second fixed part through the wire feeding hole, and are cut off by the hydraulic shear after a certain length. From the wire feeding direction, the head of the rear reinforcing steel bar is cut off, and the cut reinforcing steel bar falls into the wire feeding groove and is pushed by the protruding part of the second moving part to move in the inward wire feeding channel.

[0032] In actual operation, because the tail of the reinforcing steel bar cut off by the hydraulic shear is raised, when the second moving part is used for pushing, the raised tail of the reinforcing steel bar may sometimes enter the wire feeding hole by mistake, causing failure of wire feeding or wire feeding defects. Therefore, a baffle 26-6 is arranged on the vertical part of the second moving part. The baffle includes a vertical part 26-6-1 and a horizontal part 26-6-2 which are connected at a substantially ninety-degree angle, such as being connected as a whole. The vertical part of the baffle is connected with the vertical part of the second moving part, and the horizontal part of the baffle is connected with the bottom end of the vertical part of the baffle and located above the wire feeding groove of the second fixed part and parallel to the length direction of the wire feeding groove. A communicating hole 26-6-4 is arranged on the vertical part of the baffle and matched with the wire feeding hole 26-5 arranged on the vertical part of the second moving part. A third connecting hole 26-6-3 is arranged on the vertical part of the baffle and matched with a second connecting hole 26-7 arranged on the vertical part of the second moving part. The vertical part of the baffle is connected with the vertical part of the second moving part by a screw or a bolt, so as to realize the connection of the baffle and the second moving part.

[0033] In use, the reinforcing steel wire passes through the wire feeding through hole, the communication hole and enters the second fixing component, and the length is fixed, and then the hydraulic shear cuts the reinforcing steel wire. From the wire feeding direction, the head of the reinforcing steel wire is cut off, and the tail of the reinforcing wire is cut off. The cut reinforcing steel wire (i.e. the reinforcing steel wire in front of the wire feeding direction) is ejected from the horizontal part of the baffle. At this time, the cut reinforcing steel wire falls into the wire feeding groove. Due to the existence of the horizontal part of the baffle, even if the tail of the cut reinforcing steel wire is raised, it cannot mistakenly enter the wire feeding through hole, thereby ensuring the continuity of wire feeding.

[0034] The reinforcing wire tying machine (such as a top wire feeding reinforcing wire tying machine, a full-automatic mechanical hand reinforcing wire tying machine, a reinforcing wire tying machine based on a driven opening and closing clamp block device, and a reinforcing wire tying machine using a jacking mechanism) installed and used with the above wire feeding mechanism uses the wire feeding mechanism of the application to replace the original “outer wire feeding channel”, uses the wire feeding groove of the second fixing component as the wire feeding channel, and widens the wire feeding channel of the opening and closing guide pipe according to the needs of the “inner wire feeding channel”, and at the same time meets the needs of conveying one or more reinforcing steel wires. For example, when two reinforcing steel wires are needed, the diameter of the wire feeding channel of the opening and closing guide pipe is slightly larger than the diameter of the two reinforcing steel wires. The entire reinforcing wire tying machine uses the wire feeding groove of the second fixing component as the wire feeding channel, and uses the second moving component to push the reinforcing steel wire to realize wire feeding for the mechanical hand and the inner wire feeding channel. In this way, one reinforcing steel wire can be fed one by one, or multiple reinforcing steel wires (such as two reinforcing steel wires) can be fed, so that one reinforcing steel wire or multiple reinforcing steel wires can be tied at a certain tying position. After wire feeding, the first moving component drives the second moving component to return to the original position close to the hydraulic shear. After the reinforcing steel wire is processed by the hydraulic shear and falls into the wire feeding groove, subsequent wire feeding is performed. For the entire reinforcing wire tying machine, the reinforcing steel wire retains the original wire feeding mode (such as cutting off the tail of the previous reinforcing steel wire with the head of the next reinforcing steel wire) before the hydraulic shear and after falling into the wire feeding groove. After the reinforcing steel wire falls into the wire feeding groove, the original wire feeding mode is abandoned, and push-type wire feeding is adopted. In the case of ensuring the safety of wire feeding, the efficiency of wire feeding is improved. Such design provides convenience for new customers and takes into account the usage habits of old customers.

[0035] The above is an exemplary description of the application. It should be noted that any simple modification, change or other equivalent replacement that does not deviate from the core of the application and can be made by those skilled in the art without creative labor falls within the protection scope of the application.
