[0068] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The description of the exemplary embodiments is intended to apply to various alternative embodiments as well. The following description is not intended to be exhaustive or to limit the application to the precise form disclosed. Many modifications and variations are possible in light of this disclosure. It is intended that the scope of the application be defined by the claims appended hereto rather than by the description of the exemplary embodiments. All articles, patents, and other publications that have been cited in this disclosure are incorporated herein by reference.

[0069] The terms "first", "second", "third", "fourth", and the like in the description and in the claims, where they occur, are used as labels for nouns that they precede, and do not necessarily describe a relationship with, or sequence in time, the other objects described. It will be understood that the use of such terms is merely for distinguishing between the objects described, and not for describing a specific order or sequence in time between such objects. Further, the terms "comprise" and "have," and variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, product, or apparatus that comprises a list of elements is not necessarily limited to those elements, but can include other elements not expressly listed or inherent to such process, method, system, product, or apparatus.

[0070] As mentioned in the background section, when the bent material strip passes between the two extrusion rollers, the two sides of the material strip will be aligned for subsequent high-frequency welding into a tube. However, for an ultra-thin material strip (such as a wall thickness of less than 0.2 mm), the material strip is weak in elasticity and easy to deform, and it is difficult to be tightly attached to the extrusion rollers, so that the two sides of the material strip are difficult to align, that is, the butt joint of the two sides of the material strip is misaligned or out of layer. The technical requirement in the existing high-frequency welding is that the out-of-layer degree cannot exceed 15% of the thickness of the material strip. If the out-of-layer degree exceeds the range, the welding requirement cannot be met, and defects such as poor welding are caused, thereby seriously affecting the product quality, causing waste, and reducing the yield and production capacity of the product.

[0071] To solve the above problems in the prior art, the application provides an auxiliary feeding device and a roll bending pipe machine. The auxiliary feeding device provided by the application comprises two supporting mechanisms and two material guiding mechanisms. The material guiding mechanism comprises a driving assembly. The two driving assemblies are correspondingly and oppositely arranged on the two supporting mechanisms, and when the material strip is fed to the roll bending pipe machine, the two driving assemblies drive the opposite two sides of the material strip entering the extrusion rollers to move away from each other, so that the surfaces of the two sides of the material strip are respectively in rolling contact with the surfaces of the two extrusion rollers, facilitating subsequent welding into a tube, and effectively avoiding or reducing the misalignment of the two sides of the material strip, thereby ensuring the product quality.

[0072] The technical solutions of the application will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described in detail in some embodiments.

[0073] Please refer to Figures 1-4 The auxiliary feeding device provided by the embodiment of the application is used for feeding the bent material strip 20 to the roll bending pipe machine 10. The roll bending pipe machine 10 oppositely comprises two extrusion rollers 11. The auxiliary feeding device comprises two supporting mechanisms 100 and two material guiding mechanisms 200.

[0074] The material guiding mechanism 200 comprises a driving assembly 210. The two driving assemblies 210 are correspondingly and oppositely arranged on the two supporting mechanisms 100, and are configured to drive the opposite two sides of the material strip 20 entering the extrusion rollers 11 to move away from each other when the material strip 20 is fed to the roll bending pipe machine 10, so that the surfaces of the two sides of the material strip 20 are respectively in rolling contact with the surfaces of the two extrusion rollers 11.

[0075] The roll bending pipe machine 10 in the embodiment is used for extruding and bending the long strip-shaped material strip 20, aligning the two sides of the material strip 20, and then sealing the two sides of the material strip 20 by high-frequency welding, so as to form a tubular structure. Therefore, the roll bending pipe machine 10 is provided with at least two opposite extrusion rollers 11 and a high-frequency welding unit. The cavity between the two extrusion rollers 11 is the cross-sectional shape of the tube.

[0076] In this embodiment, the strip 20 can be a strip of thin plate or sheet, such as stainless steel strip. The auxiliary feeding device can be used to assist in conveying the strip 20 to the roller bending tube forming machine 10, so that the strip 20 is close to the two extrusion rollers 11, so as to carry out the next high-frequency welding process.

[0077] In this embodiment, the support mechanism 100 is used for support and to provide an installation foundation. It can be in the form of a bracket, frame, or shell, and can be integrally formed or spliced ​​together. Two support mechanisms 100 can be arranged opposite each other on the roll bending tube forming machine 10, and there is a conveying station between them.

[0078] The material guiding mechanism 200 in this embodiment includes at least a driving component 210. The driving component 210 is used to drive the material strip 20 to press against the extrusion roller 11. In one example, the driving component 210 can be a non-contact suction cup, which can be used to pick up the material strip 20 made of materials such as stainless steel, and continuous feeding can be used during high-frequency welding. In another example, the driving component 210 can be composed of components such as magnets, used to pick up the material strip 20 made of materials such as ferromagnets, and step feeding can be used during high-frequency welding, that is, feeding one section after another after welding, ensuring that the material strip 20 is tightly gripped during the welding process.

[0079] The two drive components 210 are arranged opposite each other and are respectively arranged on the two support mechanisms 100, that is, the drive components 210 and the support mechanisms 100 correspond one-to-one, which facilitates the adjustment of the distance between the two drive components 210. The two drive components 210 are located on both sides of the conveying station and are used to drive the two sides of the material belt 20 away from each other to form a bulge.

[0080] Specifically, combined Figure 1 , Figure 5 As shown, when the bent strip 20 is assisted in being conveyed to the roller bending machine 10, the strip 20 first passes between two drive components 210, and then between two extrusion rollers 11. The two drive components 210 respectively drive the opposite sides of the strip 20 away from each other. Figure 5 The drive assembly 210 on the left side drives the left surface of the conveyor belt 20 along... Figure 5 The X-axis moves in the opposite direction so that the left side surface of the strip 20 is in contact with... Figure 5 The surface of the left-hand extrusion roller 11 makes rolling contact, while Figure 5 The drive assembly 210 on the right side drives the right surface of the conveyor belt 20 along... Figure 5 The X-axis moves in the positive direction so that the right side surface of the strip 20 is in contact with... Figure 5 The surface of the extrusion roller 11 on the right side of the middle rolls into rolling contact.

[0081] It can be understood that the application of the auxiliary feeding device in the embodiment effectively avoids or reduces the misalignment of the two sides of the material belt 20, at least makes the misalignment degree of the two sides of the material belt 20 within a controllable range, and guarantees the requirements of high-frequency welding, thereby guaranteeing the product quality.

[0082] Therefore, the auxiliary feeding device provided in the embodiment of the application includes two supporting mechanisms 100 and two material guiding mechanisms 200, wherein the material guiding mechanism 200 includes a driving assembly 210, the two driving assemblies 210 are correspondingly and oppositely arranged on the two supporting mechanisms 100, and when the material belt 20 is auxiliary fed to the roll forming pipe machine 10, the two driving assemblies 210 are used to drive the opposite two sides of the material belt 20 entering the extrusion rollers to move away from each other, so that the surfaces of the two sides of the material belt 20 are correspondingly in rolling contact with the surfaces of the two extrusion rollers 11, facilitating subsequent welding into a pipe, effectively avoiding or reducing the misalignment of the two sides of the material belt 20, and guaranteeing the product quality.

[0083] In a possible design, the driving assembly 210 includes a first mounting base 211 and a driving member 212 connected to the first mounting base 211.

[0084] The first mounting base 211 is correspondingly connected to the supporting mechanism 100, and the driving member 212 is used to drive the opposite two sides of the material belt 20 entering the extrusion rollers to move away from each other.

[0085] Specifically, as shown in Figure 2 , Figure 3 , the first mounting base 211 is used to provide a mounting base, which can be in a block shape, a plate shape, a shell shape, or the like, and the first mounting base 211 can be connected to the corresponding supporting mechanism 100 by screwing, welding, clamping, or the like.

[0086] Moreover, the driving member 212 can also be connected to the corresponding first mounting base 211 by screwing, welding, clamping, or the like, which facilitates manufacturing, installation, replacement, and the like. The specific structure and shape of the first mounting base 211 are determined according to the structure type of the driving member 212, and the embodiment is not limited in this regard.

[0087] Exemplarily, in the embodiment, the driving member 212 is a cyclone suction cup. As shown in Figure 4 , one side of the suction cup has a suction surface 2121, the periphery of the suction surface 2121 has a plurality of air outlets, and when the air outlets spray air to the periphery, a cyclone airflow is formed. According to Bernoulli's principle, a negative pressure area is formed in the middle region of the suction surface 2121. Since air is blown on one side and suction is performed on the other side, non-contact suction can be achieved.

[0088] In this way, the suction cup can adsorb the material belt 20 without contacting it, thus ensuring continuous conveying of the material belt 20 and guaranteeing continuous processing. The specific model and specifications of the cyclone suction cup can be determined according to actual needs; this embodiment does not impose excessive restrictions.

[0089] Furthermore, in this embodiment, a mounting groove 2111 matching the driving member 212 is provided on one side of the first mounting base 211, and the driving member 212 is installed in the mounting groove 2111.

[0090] Specifically, such as Figure 2 , Figure 3 As shown, a circular mounting groove 2111 is provided on one side of the first mounting base 211. The driving component 212 can be embedded in the mounting groove 2111 to ensure stability. The driving component 212 can be fixed by screws, snap-fits, or other methods, facilitating installation and replacement. Of course, the first mounting base 211 should also have a slot for easy placement of the air tube, etc. The specific shape and size of the mounting groove 2111 depend on the specific structure of the driving component 212, and no excessive restrictions are imposed in this embodiment.

[0091] In some embodiments, the guiding mechanism 200 further includes a guiding roller assembly 220, which is disposed on at least one side of the drive member 212 along the conveying direction of the material belt 20, and the guiding roller assembly 220 is used to provide guidance for the material belt 20.

[0092] For example, such as Figures 1-3 As shown, the guide roller assembly 220 can be mounted on the drive member 212 as follows: Figure 1 The two sides in the Y-axis direction can also be set on one side of the drive component 212. With this setting, the guide roller assembly 220 supports and guides the material belt 20, thereby keeping the distance between the drive component 212 and the material belt 20 stable, reducing the vibration of the material belt 20, and thus ensuring the stability of the auxiliary conveyor belt 20.

[0093] Furthermore, in this embodiment, the guide roller assembly 220 includes a guide roller 221 and two second mounting seats 222. The two second mounting seats 222 are connected to the first mounting seat 211, and the guide roller 221 is rotatably mounted on the two second mounting seats 222.

[0094] The peripheral wall of the guide roller 221 has a concave arc surface 2211, which is used for rolling contact with the surface corresponding to the material belt 20.

[0095] Specifically, such as Figure 2 , Figure 3As shown, the second mounting base 222 is used to provide a mounting base, which can be in a block, plate, shell or the like structure, and the second mounting base 222 can be connected to the corresponding first mounting base 211 by screwing, welding, clamping or the like.

[0096] The two ends of the material guide roller 221 can be rotatably arranged on the second mounting base 222 through bearings or the like, so that the material guide roller 221 can rotate around the Z axis in the Figure 3 The peripheral wall of the material guide roller 221 has a concave arc surface 2211, which is consistent with the arc surface on the extrusion roller 11, so as to facilitate the smooth conveying of the material belt 20 to the extrusion roller 11.

[0097] Further, in the embodiment, the second mounting base 222 is slidingly connected with the first mounting base 211, and the second mounting base 222 slides relative to the first mounting base 211 along the first direction to adjust the distance between the material guide roller 221 and the material belt 20.

[0098] In this way, in combination with Figures 1-3 As shown, the second mounting base 222 can slide relative to the first mounting base 211 along the first direction, and the first direction is shown along the X axis direction in Figure 3 , so as to adjust the distance between the material guide roller 221 and the material belt 20.

[0099] Exemplarily, in the embodiment, one of the second mounting base 222 and the first mounting base 211 is provided with a sliding groove 2221, and the other is provided with a protrusion 2112 matched with the sliding groove 2221, and the protrusion 2112 is slidingly connected with the sliding groove 2221.

[0100] In one example, as shown in Figure 2 , the second mounting base 222 is provided with a sliding groove 2221, which can be a waist-shaped, and the first mounting base 211 is provided with a protrusion 2112 matched with the sliding groove 2221, which can be a bolt, a latch or the like, and is detachably connected with the first mounting base 211. By slidingly connecting the protrusion 2112 with the sliding groove 2221, the second mounting base 222 can be moved along the X axis direction in Figure 3 to adjust the position, and after adjustment, the protrusion 2112 can be locked with the sliding groove 2221.

[0101] In another example, not shown in the figure, the sliding groove 2221 can also be arranged on the first mounting base 211, and the protrusion 2112 can also be arranged on the second mounting base 222. In this way, the second mounting base 222 can also be slidingly connected with the protrusion 2112 and the sliding groove 2221, so as to move along the X axis direction in Figure 3 to adjust the position. For this purpose, it can be determined according to actual requirements, and in the embodiment, it is not specifically limited.

[0102] Further, in the embodiment, the material guiding roller assembly 220 further comprises two bearing seats 223, the two bearing seats 223 are oppositely connected to the second mounting base 222, and the two ends of the material guiding roller 221 are connected to the two bearing seats 223 through bearings respectively.

[0103] Specifically, as shown in Figure 2 、 Figure 3 , the bearing seat 223 is used to provide a mounting base, which can be in a block, plate, shell or other structure, and the bearing seat 223 can be connected to the two sides of the second mounting base 222 by screwing, welding, clamping or other means, and the two bearing seats 223 are oppositely arranged.

[0104] Moreover, the two ends of the material guiding roller 221 are connected to the two bearing seats 223 through bearings respectively, which facilitates the manufacturing, installation and replacement of various components. The specific type and specification of the bearing seat 223 and the bearing can be determined according to actual needs, which are not limited in the embodiment.

[0105] Further, in the embodiment, the material guiding roller assembly 220 in each material guiding mechanism 200 is provided in two groups, and the two groups of material guiding roller assemblies 220 are sequentially arranged along the conveying direction and are respectively located on the two sides of the driving member 212.

[0106] In this way, as shown in Figure 1 、 Figure 5 , the two groups of material guiding roller assemblies 220 assist in supporting the material belt 20 on both sides of the driving member 212, thereby ensuring the stability of the conveying. The conveying direction is shown along the positive direction of the Y-axis in Figure 5 .

[0107] In some embodiments, the supporting mechanism 100 comprises a base 110 and a support 120, the two bases 110 are oppositely arranged, and the two supports 120 are correspondingly arranged on the two bases 110.

[0108] The two driving assemblies 210 are correspondingly arranged on the two supports 120, and the support 120 moves relative to the corresponding base 110 along the second direction to adjust the distance between the corresponding driving assembly 210 and the corresponding extrusion roller 11 along the conveying direction of the material belt 20.

[0109] Specifically, as shown in Figure 1 、 Figure 5 , the base 110 provides a mounting base, which can be in a block, plate, shell or other structure, and the base 110 is used to be connected to the roller bending pipe machine 10, and the two bases 110 are oppositely arranged. The support 120 can be connected to the corresponding base 110 by screwing, welding, clamping or other means, and the driving assembly 210 is correspondingly connected above the support 120.

[0110] Among them, the bracket 120 moves relative to the corresponding base 110 along the second direction, such as along... Figure 5 As shown in the Y-axis direction, this facilitates the adjustment of the distance between the drive assembly 210 and the corresponding extrusion roller 11 along the conveying direction of the belt 20.

[0111] Furthermore, in this embodiment, the bracket 120 includes a first support member 121 and a second support member 122 disposed on the first support member 121. The first support member 121 is disposed on the corresponding base 110, and the two drive components 210 are disposed on the two second support members 122 respectively.

[0112] The second support member 122 moves relative to the corresponding first support member 121 in a third direction to adjust the distance between the corresponding drive assembly 210 and the corresponding extrusion roller 11 in the extrusion direction.

[0113] Specifically, such as Figure 1 , Figure 2 As shown, both the first support member 121 and the second support member 122 serve a supporting function. Both can be structural members such as rods, plates, strips, or frames. The first support member 121 is erected on the corresponding base 110, and the second support member 122 is arranged laterally on the corresponding first support member 121. The drive assembly 210 is arranged on the corresponding second support member 122.

[0114] Wherein, the second support member 122 moves relative to the corresponding first support member 121 in a third direction, such as along Figure 5 As shown in the X-axis direction, the third direction is consistent with or parallel to the first direction. This makes it easier to adjust the distance of the corresponding drive component 210 relative to the corresponding extrusion roller 11 along the extrusion direction, so that the material strip 20 is in close contact with the extrusion roller 11.

[0115] Furthermore, in this embodiment, the second support member 122 moves relative to the corresponding first support member 121 in the fourth direction to adjust the height of the corresponding drive assembly 210 relative to the corresponding extrusion roller 11.

[0116] In addition, the second support member 122 moves relative to the corresponding first support member 121 in the fourth direction, such as along... Figure 5 As shown in the Z-axis direction. This makes it easier to adjust the height of the corresponding drive component 210 relative to the corresponding extrusion roller 11, preventing the material strip 20 from deviating from the extrusion roller 11 and ensuring the accuracy of the position of the material strip 20 on the extrusion roller 11.
