Description

Technical Field

[0001] The invention relates to the technical field of packaging, in particular to a steel belt guided baler. Background Art

[0002] Steel strapping machine refers to a device that uses steel strapping to strap products or packages. It is widely used in the fields of steel pipe logistics, transportation and warehousing, such as Figure 6 As shown, when bundling steel pipes, the steel pipes are usually stacked into a honeycomb shape, that is, a hexagonal arrangement, and then the stacked steel pipes are bundled with steel belts to improve the stability and safety of the stacked steel pipes.

[0003] Existing steel strapping machines usually use a roller magnetic ring guide as the steel strap guiding mechanism. Through the coordinated action of magnetic attraction, the roller and the mechanical guidance of the side plates on both sides, the steel strap is made to surround the outside of the stacked steel pipe along a preset ring path. Then the steel strapping machine first puts the end of the steel strap tightly against the stacked steel pipe, and then tightens, buckles and cuts the steel strap to achieve bundling of the stacked steel pipes.

[0004] The following problems exist in the existing bundling of steel pipes: 1. The steel belt deflects or even derails along the axial direction of the steel pipe: when the end of the steel belt is pressed against the stacked steel pipe and the steel belt is tightened, the steel belt is in a bent and relaxed state during this process. Especially when the width of the steel belt is less than the distance between the two side plates, the side of the steel belt cannot be limited. As a result, the relaxed and bent steel belt may deflect along the axial direction of the steel pipe or even deviate from the annular guide under the action of its elasticity, which requires stopping the machine and resetting the steel belt, reducing the packaging efficiency of the stacked steel pipes.

[0005] 2. Loose bundling: Currently, the steel strip is tightened only by tightening the top. Since steel pipes are usually stacked in a honeycomb shape, the steel strip needs to cross multiple corners of the hexagon during the tightening process. Every time it passes a corner, the contact friction between the steel strip and the steel pipe will cause tension loss, resulting in uneven tension distribution of the steel strip corresponding to the lower side of the hexagon during the tightening process. As a result, the steel strip may be partially too tight or too loose after bundling, affecting the bundling quality of the stacked steel pipes. Summary of the Invention

[0027] The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product instructions shall be followed.

[0028] See Figure 1 and Figure 6A steel belt guided baler includes a base 1, on which a strapping unit 2 is installed. The strapping unit 2 includes an annular guide rail 21, on which two tensioning units 3 are symmetrically arranged front and back are installed. A leveling unit 4 is installed at a position corresponding to the annular guide rail 21 on the base 1. Two gathering units 5 symmetrically arranged left and right are also installed on the base 1. The gathering units 5 are used to gather and stack hexagonal steel pipes.

[0029] It should be noted that the strapping unit 2 includes a mounting frame fixedly mounted on the middle part of the upper end of the base 1, and the annular guide rail 21 is fixedly mounted on the mounting frame. The middle part of the upper end of the annular guide rail 21 is set as an open structure, and a packing mechanism 22 is installed on the mounting frame. The packing mechanism 22 adopts the existing technology. The packing mechanism 22 is used to feed the steel belt from the opening of the annular guide rail 21 to the annular guide rail 21. At the same time, the packing mechanism 22 can also make the end of the steel belt close to the stacked steel pipe, and tighten, bite and cut the steel belt. The annular guide rail 21 adopts the existing technology. It is adsorbed on the surface of the steel belt by magnets and guided by the side plates and bearings on both sides to achieve the surrounding state of the steel belt on the stacked steel pipe during packaging. A conveyor roller assembly is installed on the upper right end of the base 1. The conveyor roller assembly is used to convey the stacked steel pipe to the right.

[0030] The present invention is used for packing steel pipes after stacking, and when the end of the steel belt is pressed against the stacked steel pipe and the steel belt is tightened, the present invention can keep the steel belt in a straight state, and arrange the steel belt and the annular guide rail 21 in the center left and right, thereby preventing the steel belt from deflecting or derailing along the axial direction of the steel pipe, ensuring the packing efficiency of the stacked steel pipes, and at the same time, the present invention can also flatten the steel belt from the middle to both sides along the lower side contour of the hexagon, so that the tension of the steel belt corresponding to the lower side contour is evenly distributed, preventing the steel belt from being too loose or too tight after bundling, and ensuring the bundling quality of the stacked steel pipes.

[0031] Specifically, the stacked steel pipes (in a hexagonal honeycomb shape) are first transported to the annular guide rail 21 through external conveying equipment, and the bundling position of the stacked steel pipes is aligned with the middle of the annular guide rail 21. At the same time, the steel belt is fed from the opening of the annular guide rail 21 into the annular guide rail 21 through the packaging mechanism 22, and then the two gathering units 5 are controlled to gather the stacked steel pipes. Then, the packaging mechanism 22 is controlled to make the end of the steel belt close to the stacked steel pipe. In this process, the steel belt is in a tensioned and straightened state under the action of the tensioning unit 3. At the same time, the tensioning unit 3 can also arrange the steel belt and the annular guide rail 21 in the center left and right, so that the bundling position of the steel belt and the stacked steel pipes is accurately aligned. Then, when the width of the steel belt is less than the distance between the two side plates, the steel belt can be prevented from skewing or derailing along the axial direction of the steel pipe.

[0032] The packaging mechanism 22 is controlled again to tighten the steel belt. During the tightening process of the steel belt, the steel belt is still in a straight state under the action of the tensioning unit 3, and is arranged in the center of the annular guide rail 21. When the steel belt fits on the lower side of the hexagon, the flattening unit 4 is controlled to flatten the steel belt from the middle to both sides along the lower side contour of the hexagon. After the steel belt is tightened, the packaging mechanism 22 is controlled to perform operations such as biting and cutting the steel belt. Finally, the external conveying equipment and the conveying roller assembly are controlled to convey the stacked steel pipes to the right, and the above operations are repeated to realize the packaging operation of the stacked steel pipes.

[0033] See Figure 1 、 Figure 4 and Figure 6 The gathering unit 5 includes a pressurizing group 51 installed on the base 1, and two L-shaped transmission plates 52 arranged symmetrically in front and back are installed on the pressurizing group 51. Gathering plates 53 are fixedly installed on the opposite sides of the upper ends of the horizontal sections of the two transmission plates 52, and the upper ends of the two gathering plates 53 are arranged inclined in a direction away from each other.

[0034] See Figure 1 and Figure 4 The pressurizing group 51 includes two pressurizing plates 511 symmetrically arranged front and back and slidingly mounted on the base 1. A synchronizer 512 is connected between the two pressurizing plates 511 and the base 1. The upper end of the pressurizing plate 511 and the vertical end of its corresponding transmission plate 52 are slidably connected front and back. A pressurizing spring 513 is connected between the pressurizing plate 511 and the transmission plate 52.

[0035] It should be noted that the synchronous part 512 includes a synchronous screw 1, which is provided with two threaded sections arranged in front and behind and with opposite rotation directions. The two pressure plates 511 are connected to their corresponding threaded sections by threaded cooperation, and the synchronous screw 1 is rotatably connected to the base 1. The front end of the synchronous screw 1 is fixedly connected to the output shaft of the motor 1 fixedly mounted on the base 1. By starting the motor 1 to drive the synchronous screw 1 to rotate, the synchronous screw 1 drives the corresponding two pressure plates 511 to move synchronously toward each other.

[0036] The gathering unit 5 is used to gather the stacked steel pipes; specifically, when the external conveying equipment conveys the stacked steel pipes into the annular guide rail 21 and aligns the bundling position of the stacked steel pipes with the middle of the annular guide rail 21, the synchronous member 1 512 is controlled to drive the two pressure plates 511 to move in a direction close to each other, so that the pressure plate 511 drives the two transmission plates 52 to move in a direction close to each other through the pressure spring 513, and the transmission plate 52 moves to the lower horizontal section where the steel pipes are stacked in a honeycomb shape, i.e., a hexagonal arrangement, and contacts it, and the two transmission plates 52 drive the gathering plate 53 to move synchronously and press against it. The inclined surface on the lower side of the hexagon, and as the two pressure plates 511 move, the pressure spring 513 is compressed, and then under the action of the pressure spring 513, the two front and rear arranged transmission plates 52 and gathering plates 53 can gather the stacked steel pipes in the direction of approaching each other, and the packaging mechanism 22 presses down the upper side of the hexagon, thereby ensuring that the steel pipes are tightly gathered together, further ensuring the bundling quality of the stacked steel pipes. When the bundling of the steel pipes is completed, the control synchronization member 512 finally drives the transmission plate 52 and the gathering plate 53 to return to their initial position in the direction of moving away from each other through the two pressure plates 511.

[0037] See Figure 1 、 Figure 2 、 Figure 3 and Figure 6 The tensioning unit 3 includes an arc-shaped mounting plate 31 fixedly mounted on the left and right sides of the annular guide rail 21 through a plurality of connecting blocks. A tensioning rod 33 is mounted on the inner arc surface of the arc-shaped mounting plate 31 through a plurality of elastic connecting groups 32 evenly arranged in an arc shape. The two tensioning rods 33 arranged on the left and right sides are arranged in contact with each other on opposite sides and are both arranged as a frustum structure. A centering limit group 34 is mounted on the tensioning rod 33. A linkage group 35 is mounted on the opposite sides of the two arc-shaped mounting plates 31. The linkage group 35 and the tensioning rod 33 cooperate to drive the centering limit group 34 to arrange the steel belt and the annular guide rail 21 in the center left and right.

[0038] The tensioning unit 3 is used to keep the steel belt in a straight state; specifically, when the packing mechanism 22 is controlled to make the end of the steel belt close to the stacked steel pipe, during this process, the part of the steel belt close to the packing mechanism 22 first moves toward the direction of the stacked steel pipe and moves out of the annular guide rail 21, and as the packing mechanism 22 drives the end of the steel belt to move downward, the steel belt gradually moves out of the annular guide rail 21, and the steel belt can be sequentially fitted on the two tensioning rods 33 arranged on the left and right from top to bottom. Under the action of the truncated cone structure of the two tensioning rods 33, the opposite sides of the two tensioning rods 33 are aligned with the left and right centers of the steel belt, thereby making the steel belt and the annular guide rail 21 straight. The circular guide rail 21 is aligned in the center left and right. As the packaging mechanism 22 tightens the steel belt, the steel belt is in a straight state under the action of the left and right tensioning rods 33, thereby preventing the steel belt from being in a bent and relaxed state, and preventing the steel belt from being deflected or derailed along the axial direction of the steel pipe. The linkage group 35 is started to drive the centering limit group 34 to perform secondary centering alignment on the steel belt through the tensioning rod 33, further ensuring that the steel belt is always aligned in the center left and right with the annular guide rail 21, so that the bundling position of the steel belt and the stacked steel pipe is accurately aligned, further preventing the steel belt from being deflected or derailed along the axial direction of the steel pipe, and ensuring the packaging efficiency of the stacked steel pipes.

[0039] When the packaging mechanism 22 presses the end of the steel belt against the stacked steel pipe and tightens the steel belt, the linkage group 35 is controlled to return to its initial position. The steel belt can cooperate with the cone structure of the two tensioning rods 33 arranged on the left and right from top to bottom, and drive the two tensioning rods 33 to move away from each other, so that the steel belt is separated from between the two tensioning rods 33, so that the packaging mechanism 22 can complete operations such as tightening, buckling and cutting the steel belt.

[0040] See Figure 1 、 Figure 2 and Figure 3 The elastic connection group 32 includes a connecting plate 321 fixedly mounted on the arc-shaped mounting plate 31, and the tensioning rod 33 slides left and right through the corresponding connecting plate 321. A return spring 322 is connected between the tensioning rod 33 and its corresponding connecting plate 321.

[0041] See Figure 1 、 Figure 2 and Figure 3The linkage group 35 includes an arc-shaped electric slider assembly 351 installed on the arc-shaped mounting plate 31, and an arc plate 352 is installed on the side of the arc-shaped electric slider assembly 351 away from the arc-shaped mounting plate 31. A plurality of linkage wedge blocks 353 are arranged on the side of the arc plate 352 away from the arc-shaped mounting plate 31. The distribution positions of the linkage wedge blocks 353 correspond one-to-one to the installation positions of the tensioning rods 33. The left and right tensioning rods 33 are both set to have a hemispherical structure on their opposite sides and are in contact with the corresponding linkage wedge blocks 353 on the oblique surface. The linkage wedge blocks 353 are fixedly connected to the corresponding arc-shaped plate 352 through an L-shaped connecting rod 354; a plurality of arc-shaped synchronization connecting rods 355 are fixedly installed on the opposite sides of the left and right arc plates 352, and the synchronization connecting rods 355 are located on the outside of the arc-shaped mounting plate 31.

[0042] See Figure 3 Circumferentially distributed slots 331 are provided on opposite sides of the two tensioning rods 33 arranged on the left and right sides, and the slots 331 are used to connect the ends of the two tensioning rods 33 arranged on the left and right sides together.

[0043] It should be noted that the arc-shaped electric slider assembly 351 includes an arc-shaped guide rail and a plurality of electric sliders evenly arranged in an arc shape. The arc-shaped guide rail is fixedly mounted on the corresponding arc-shaped mounting plate 31. The electric slider is fixedly connected to the corresponding arc-shaped plate 352. By starting the electric slider, the corresponding arc-shaped plate 352 is driven to move along the arc-shaped track of the arc-shaped guide rail.

[0044] The linkage group 35 and the tensioning rod 33 cooperate to drive the centering limit group 34 to arrange the steel belt and the annular guide rail 21 in the center. Specifically, when the steel belt is sequentially attached to the two tensioning rods 33 arranged on the left and right from top to bottom, the electric slider drives the arc plate 352 to move downward along the arc track of the arc guide rail. Under the action of the synchronous link 355, it is ensured that the left and right arc plates 352 can move synchronously. The arc plate 352 drives the linkage wedge block 353 to move through the L-shaped link 354, and the linkage wedge block 353 is connected to the arc plate 352. The inclined surface 53 and the hemispherical structure of the corresponding tensioning rod 33 cooperate to drive the left and right tensioning rods 33 to move toward each other, and the tensioning rod 33 compresses the corresponding return spring 322. Under the action of the slot 331, the ends of the left and right tensioning rods 33 can be plugged together, and the left and right tensioning rods 33 drive the corresponding centering limit group 34 to perform secondary centering alignment on the steel belt, further ensuring that the steel belt is always aligned with the left and right centers of the annular guide rail 21, so that the bundling position of the steel belt and the stacked steel pipes is accurately aligned.

[0045] When the packaging mechanism 22 presses the end of the steel belt against the stacked steel pipe and tightens the steel belt, the arc-shaped electric slider assembly 351 is controlled to drive the linkage wedge block 353 to move to the initial position, and the left and right tensioning rods 33 move away from each other to the initial position under the action of the corresponding reset springs 322, so that the steel belt is now in contact with the conical structure of the left and right tensioning rods 33, and when the packaging mechanism 22 tightens the steel belt, the steel belt can first cooperate with the conical structure of the left and right tensioning rods 33 on the upper side, and drive the left and right tensioning rods 33 on the upper side to move away from each other, so that the steel belt is separated from between the left and right tensioning rods 33 on the upper side. As the packaging mechanism 22 tightens the steel belt, the steel belt can still be in a straight state under the action of the remaining two left and right tensioning rods 33, and gradually separate from the corresponding two tensioning rods 33 from top to bottom.

[0046] See Figure 2 and Figure 3 The centering limit group 34 includes a centering limit plate 341 slidably mounted on the tension rod 33 , and a plurality of circumferentially evenly arranged extension springs 342 are connected between the centering limit plate 341 and the tension rod 33 .

[0047] When the two tensioning rods 33 on the left and right sides move in the direction of approaching each other and the ends of the two tensioning rods 33 are plugged together, the two tensioning rods 33 arranged on the left and right sides drive the corresponding two centering limit plates 341 to move in the direction of approaching each other, so that the two centering limit plates 341 are tightly attached to the left and right sides of the steel belt, and as the two tensioning rods 33 move in the direction of approaching each other, the two centering limit plates 341 perform secondary centering of the steel belt under the action of their corresponding extension springs 342, further ensuring that the steel belt and the annular guide rail 21 are always aligned in the center of the left and right, so that the bundling position of the steel belt and the stacked steel pipes is accurately aligned, thereby further ensuring the packaging efficiency of the stacked steel pipes, and when the two tensioning rods on the left and right sides move in the direction of moving away from each other to the initial position under the action of the corresponding return springs 322, the tensioning rod 33 drives the corresponding centering limit plates 341 to move to the initial position through the extension springs 342.

[0048] See Figure 1 、 Figure 4 、 Figure 5 and Figure 6The flattening unit 4 includes two front-to-back symmetrically arranged synchronization groups 41 installed on the base 1. Two left-to-right symmetrically arranged elastic clamping rods 42 are installed on the synchronization group 41. The upper ends of the elastic clamping rods 42 are hinged with a pulling plate 43. The synchronization group 41 is used to drive the pulling plate 43 along the lower side contour of the hexagon from the middle to both sides through the elastic clamping rods 42 to flatten the steel belt from the middle to both sides, so that the tension on the steel belt is evenly distributed; initially, the opposite sides of the two left-to-right pulling plates 43 are located on the left and right sides of the steel belt, and will not interfere with the steel belt moving out of the annular guide rail 21.

[0049] The flattening unit 4 is used to make the steel belt close to the lower side contour of the hexagon; specifically, when the packaging mechanism 22 tightens the steel belt and the steel belt initially fits the lower side of the stacked steel pipe, the control synchronization group 41 drives the two elastic clamping rods 42 arranged on the left and right to gradually approach, so that the opposite sides of the two pulling plates 43 arranged on the left and right are in contact, and then the two synchronization groups 41 are controlled to drive the two pulling plates 43 arranged in the front and back to move away from each other through the elastic clamping rods 42. At the same time, the synchronization group 41 drives the pulling plates 43 to elastically fit the steel belt corresponding to the lower middle part of the steel pipe stacked in a honeycomb shape, that is, a hexagonal arrangement, through the elastic clamping rods 42. Then, when the two pulling plates 43 arranged in the front and back move synchronously in the direction of moving away from each other, the front and rear pulling plates 43 pull the steel belt corresponding to the horizontal surface of the lower side of the hexagon in the direction of moving away from each other, so that the steel belt is The tension under the action of the two pulling plates 43 is evenly distributed. When the pulling plate 43 moves to the lower inclined surface of the hexagon, the pulling plate 43 flips over under the hinged action of the pulling plate 43 and the elastic holding rod 42, and the transmission plate 52 and the gathering plate 53 gather the stacked steel pipes in the direction of approaching each other. As the front and rear pulling plates 43 elastically adhere to the steel belts corresponding to the lower side contour of the hexagon and synchronously move away from each other, the front and rear pulling plates 43 flatten the steel belts from the middle to both sides along the lower side contour of the hexagon. In the process of tightening the steel belt, the tension on the steel belt corresponding to the lower side contour is evenly distributed, thereby preventing the steel belt from being too loose or too tight after bundling, and ensuring the bundling quality of the stacked steel pipes. When the bundling of the stacked steel pipes is completed, the synchronization group 41 is controlled to drive the pulling plate 43 to return to its initial position.

[0050] See Figure 4 、 Figure 5 and Figure 6A square groove is provided on the upper side of the base 1 at a position corresponding to the annular guide rail 21. The synchronization group 41 includes a synchronization plate 411. The synchronization plates 411 corresponding to the two synchronization groups 41 are slidably installed in the square groove forward and backward. A synchronization member 2 412 is commonly installed between the two synchronization plates 411 and the base 1. A lifting plate 416 is installed on the upper end of the synchronization plate 411 through a plurality of multi-stage telescopic rods 415 evenly arranged from left to right. The multi-stage telescopic rods 415 are elastically telescopic structures. Two left-right symmetrically arranged synchronization blocks 413 are installed on the upper side of the lifting plate 416 for sliding left and right through a synchronization member 3 414, and the upper ends of the synchronization blocks 413 are fixedly connected to their corresponding elastic tightening rods 42.

[0051] See Figure 4 、 Figure 5 and Figure 6 The left and right ends of the lifting plate 416 are fixedly installed with round rods 417, and the positions on the upper side of the base 1 corresponding to the round rods 417 are fixedly installed with matching plates 11. The upper ends of the opposite sides of the two matching plates 11 arranged in the front and rear are set as inclined surfaces that match the corresponding round rods 417.

[0052] It should be noted that the synchronous component 2 412 includes a synchronous screw 2, which has two threaded sections arranged front to back and with opposite rotation directions. The two synchronous plates 411 are connected to the corresponding threaded sections on the synchronous screw 2 through threaded cooperation, and the synchronous screw 2 is rotatably connected to the base 1. The front end of the synchronous screw 2 is fixedly connected to the output shaft of the motor 2 fixedly mounted on the base 1. By starting the motor 2 to drive the synchronous screw 2 to rotate, the synchronous screw 2 drives the two synchronous plates 411 to move synchronously inward and outward.

[0053] It should be noted that the synchronization component three 414 uses an electric slider assembly to drive the two synchronization blocks 413 to move synchronously. The electric slider assembly includes a slide rail and two electric sliders, wherein the slide rail and the corresponding synchronization plate 411 are fixedly connected, and the two synchronization blocks 413 are fixedly installed on the corresponding electric sliders. By starting the two electric sliders, the two synchronization blocks 413 are driven to move synchronously inward and outward.

[0054] The synchronization group 41 is used to drive the elastic holding rod 42 to move synchronously toward each other. The synchronization group 41 is also used to drive the pulling plate 43 to fit tightly against the lower side of the stacked steel pipe through the elastic holding rod 42. Specifically, when the packaging mechanism 22 tightens the steel belt and the steel belt is initially fitted against the lower side of the stacked steel pipe, the synchronization member 3 414 is controlled to drive the two elastic holding rods 42 and the pulling plate 43 arranged on the left and right to move toward each other through the synchronization block 413, so that the opposite sides of the two pulling plates 43 arranged on the left and right are in contact, and then the synchronization member 2 412 is controlled to drive the two synchronization plates 411 to move away from each other, and the synchronization plate 411 drives the two lifting plates 416 to move away from each other through the multi-stage telescopic rod 415, and Under the cooperation of the round rod 417 and the inclined surface of the matching plate 11, the lifting plate 416 moves upward and stretches the elastic telescopic end of the multi-stage telescopic rod 415. The lifting plate 416 finally drives the pulling plate 43 to stick to the lower side of the steel belt through the synchronization block 413, and the telescopic end of the elastic clamping rod 42 can be compressed, so that the steel belt is tightly attached to the steel belt corresponding to the lower horizontal surface of the hexagon. As the two lifting plates 416 continue to move away from each other, the lifting plate 416 always moves upward under the cooperation of the round rod 417 and the inclined surface of the matching plate 11. Then, when the pulling plate 43 moves to the corresponding position of the lower inclined surface of the hexagon, the telescopic end of the elastic clamping rod 42 can still be compressed, thereby ensuring that the steel belt is tightly attached to the lower side contour of the hexagon.

[0055] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
