Description

Technical Field

[0001] The invention relates to the technical field of stainless steel heat-insulating containers, and in particular to a traceless weld rolling processing device. Background Art

[0002] Welding is a critical and common process in the production of thermal insulation containers. The quality of welding on cup bodies and other container products directly impacts the appearance and performance of the container. After welding, some cup bodies are prone to uneven welds, which can be inconsistent with the original dimensions. Rolling the weld seam is necessary to facilitate subsequent polishing, ensuring the weld is as smooth as the rest of the outer surface.

[0003] However, conventional weld rolling treatment methods have shortcomings, such as easily causing scratches and damage to the product's appearance. During the weld rolling process, the uneven force applied by the roller from one side can easily cause the cup to be eccentric and out of place, affecting product quality. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a seamless weld rolling processing device, which can flatten the unevenness of the weld to ensure product quality; facilitate subsequent polishing processing; and avoid the cup body from being eccentric or even falling out during the rolling process, affecting product quality.

The servo moving part is provided with a matching servo controller to control the feed of the servo moving part, driving the rolling wheel to roll the weld of the container; the weld is rolled and the uneven parts are flattened; since the rolling wheel operates from one side, it is easy to push the container to offset and even cause the container to fall out; therefore, during the rolling process, force is applied to the inner wall of the container through the force compensation part, and the direction of the force is opposite to the direction of the rolling wheel, which plays a role in balancing the external force; thereby the force of the container is balanced to improve the processing quality of the container.

[0009] During clamping, when the inner support block clamps the inner wall of the opening of the fixed container, the pull rod is always in a tensile state on the conical block, and the inner support block can be stretched open by the conical block, the width of the dividing groove is increased, and the outer surface of the inner support block is pressed against the inner wall of the container to achieve clamping; when unloading the container, the pull rod is pulled in the opposite direction, the conical block no longer expands the inner support block outward, the inner support block is reset under the action of its own elasticity, and the width of the dividing groove is reduced.

[0011] According to the above technical means, the clamp and the force compensation part can directly cooperate with each other to provide force balance while achieving the clamping of the container, which helps to improve the processing quality when the container is flattened.

In addition, the compensation cycle of the force of the compensation block body can be controlled by controlling the frequency of the pump air, which facilitates better force balance and reduces the container offset caused by the rolling wheel during rolling.

DETAILED DESCRIPTION

[0035] The following will be combined with the accompanying 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 embodiments described 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 making creative efforts shall fall within the scope of protection of the present invention:

[0036] like Figures 1-8As shown, the embodiment of the present application discloses a seamless weld rolling processing device, including a chassis 100 and a clamp 300 for clamping a container 200; the clamp 300 includes a limit seat 101 and an inner support clamping portion 303 installed on the top surface of the chassis 100, and a transmission member 114 is rotatably installed in the limit seat 101, and the transmission member 114 adopts a long shaft sleeve, and a key groove is provided on the top inner wall of the long shaft sleeve, and a passive wheel is installed on the bottom outer wall of the long shaft sleeve; a mounting bar 112 is installed in the chassis 100, and a driver 113 is provided on the mounting bar 112, and the driver 113 is connected to the passive wheel at the bottom end of the long shaft sleeve by transmission, and the top end of the long shaft sleeve is connected to a rotating disk 302 through a key and a key groove, and the rotating disk 302 is rotatably connected to the limit seat 101; the rotating disk 302. The middle part of the transmission part 114, that is, the long shaft sleeve, is set to be hollow, forming a hollow structure such as a gap 3021, and the hollow structure is used to install the inner support clamping part 303; a force-applying gas rod 301 connected to the inner support clamping part 303 is installed in the chassis 100, and the force-applying gas rod 301 is used to drive the inner support clamping part 303 to clamp the container 200; a force compensation part 304 is installed on the rotating disk 302, and the force compensation part 304 is located above the inner support clamping part 303; a servo moving part 107 is installed above the chassis 100, and a rolling wheel 109 is installed at the output end of the servo moving part 107; the rolling wheel 109 is used to roll the welding part of the container 200, and the force compensation part 304 balances the force when the rolling wheel 109 rolls the container 200.

[0037] In this embodiment, the container 200 is a stainless steel heat-insulating container, and can also be a cylindrical stainless steel container. The top of the container 200 is open, and during the rolling operation, the container 200 is inverted. After the container 200 is internally clamped by the internal support clamping portion 303, the servo moving part 107 is started to drive the rolling wheel 109 to roll the weld of the container 200; the weld is rolled to flatten the uneven surface to make the outer surface of the container smooth; however, since the rolling wheel 109 operates from one side, it is easy to push the container 200 to the side and cause it to deviate, or even cause the container 200 to fall out; therefore, the force compensation portion 304 is used to apply force to the inner wall of the container 200, and the direction of the force is opposite to the direction of the force applied by the rolling wheel 109, thereby balancing the force on the container 200.

[0038] In some optional embodiments, an opening is provided on the side of the chassis 100, and a door 110 is mounted on the opening; components within the chassis 100 can be inspected, installed, or protected by opening and closing the door 110. The driver 113 includes a drive motor, a driving pulley mounted at the output end of the drive motor, and a drive belt connecting the driving pulley and the driven pulley. When the drive motor is activated, the driving pulley, the driving belt, and the driven belt drive the transmission member 114 to rotate, thereby driving the rotating disk 302 and the container 200 clamped by the inner support clamping portion 303 to rotate.

[0039] In some optional embodiments, such as Figure 2-4 、 Figure 8 As shown, the internal support clamping part 303 includes an internal support block 3034, a conical block 3033 and a pull rod 3031. The conical block 3033 is inserted into the internal support block 3034. The half of the internal support block 3034 close to the conical block 3033 is provided with dividing grooves in a circular array. The divided grooves are mainly used to divide the internal support block 3034 into four uniform internal support parts. The half of the internal support block 3034 away from the conical block 3033 is a tube, which can connect and fix the four internal support parts as a whole; one end of the pull rod 3031 is passed through the conical block 3033 and the internal support block 3034 and extends from the bottom of the internal support block 3034 to be connected with the force-applying gas rod 301. The other end of the pull rod 3031 is provided with a threaded section, and a nut 3032 is installed on the threaded section to limit the conical block 3033; specifically, it can be locked by two nuts 3032.

[0040] In some optional embodiments, a positioning hole is provided on the bobbin, a connecting tube is extended at the bottom of the rotating disk 302, a fixing hole corresponding to the positioning hole is opened on the connecting tube, and the inner support block 3034 is installed and fixed by inserting a rod into the fixing hole and the positioning hole.

[0041] In some optional embodiments, such as Figure 8 As shown, there are four dividing grooves, and the four dividing grooves are provided with a clearance groove 3035. In the process of pulling the conical block 3033 by the pull rod 3031, the clearance groove 3035 has a sufficient width so that the expansion of the inner support block 3034 will not affect the force compensation part.

[0042] In some optional embodiments, the servo moving member 107 includes a servo moving pair and a drive motor mounted on the servo moving pair. The output end of the drive motor is connected to the rotating shaft 104 via a coupling 108. A roller 109 is mounted on the rotating shaft 104. Specifically, an L-shaped mounting base is mounted on the top rear side of the chassis 100, and the servo moving pair is mounted on the mounting base. The servo moving pair generally includes a slide groove opened on the top of the mounting base, a slider mounted in the slide groove, and a lead screw and a polished rod rotatably mounted on the slider. The reciprocating motor is used to drive the lead screw, and the reciprocating motor drives the slider to slide in the slide groove via the lead screw.

[0043] In this embodiment, the drive motor may be selected not only as a reduction motor but also as a servo motor, a permanent magnet synchronous motor, and the like.

[0044] In some optional embodiments, such as Figure 1 、 Figure 2As shown, a first guide rail 102 is mounted on the top surface of the chassis 100, on which a synchronous slider 103 is slidably mounted. The synchronous slider 103 can be a motorized slider with a rotating sleeve mounted on it. A coupling 108 is mounted on the output end of the drive motor, and a rotating shaft 104 is mounted between the rotating sleeve and the coupling 108. A rolling wheel 109 is mounted on the rotating shaft 104. A second guide rail 105 is mounted on the back side of the chassis 100, on which an adjustment rod 106 is slidably mounted. The end of the adjustment rod 106 is mounted with a limit frame 111, which is mounted on both sides of the rolling wheel 109. The limit frame 111 does not affect the rotation of the rolling wheel 109, but can adjust the rolling wheel 109 up and down.

[0045] In some alternative embodiments, the adjustment rod 106 may be a pneumatic push rod, an electric push rod, or a hydraulic push rod. The addition of the adjustment rod 106, coupled with the drive of the servo movable member 107, allows for reciprocating processing of the weld seam of the container in a variety of directions, improving processing adaptability. The reciprocating movement of the servo movable member 107 can be used to flatten the container 200, enabling a smooth flattening operation on the weld seam of the container 200.

[0046] In some optional embodiments, such as Figure 2-6As shown, the force compensation part 304 includes a connecting frame 3041, a connecting shell 3042, a fixing sleeve 3043 and a compensation block body. The bottom end of the connecting frame 3041 is fixedly mounted on the rotating disk 302, the middle section of the connecting frame 3041 passes through the give way slot 3035, and the inner support block 3034 does not contact the connecting frame 3041 when expanded; the connecting shell 3042 is mounted on the top of the connecting frame 3041; the fixing sleeve 3043 is mounted in the middle of the connecting shell 3042, and a turbine 30413 is arranged in the fixing sleeve 3043, and the rotating shaft of the turbine 30413 is fixedly connected to the compensation block body; the limiting seat 101, the rotating disk 302, the connecting frame 3041 and the connecting shell 3042 are provided with a connecting pump air pipeline; gas is transported into the fixing sleeve 3043 through the pump air pipeline to drive the turbine 30413 to rotate to drive the compensation block body to rotate, and periodically drive the compensation block body to press against the inner wall of the container 200. The angular velocity of the compensation block body can be adjusted by the amount of pumped air pressure and airflow. The compensation block body includes a compensation block 3044 and a movable block 3045. A guide block is provided at one end of the compensation block 3044, and the movable block 3045 is slidably connected to the guide block. A counterweight block 3046 is symmetrically provided at the other end of the compensation block, which acts as a counterweight for the movable block 3045. A piston cylinder is provided within the compensation block 3044, and a piston 30411 is slidably mounted within the piston cylinder. A telescopic rod 30410 is connected between the piston 30411 and the movable block 3045. The bottom of the compensation block 3044 is provided with an air connection hole connected to the piston cylinder. Two air connection holes are provided, one on each side of the piston 30411, serving as an air supply hole and an air extraction hole, respectively, to achieve reciprocating drive of the piston 30411. A pressure relief hole is provided at the bottom of the compensation block 3044, connected to the piston cylinder. A pressure relief valve is installed on the pressure relief hole to achieve regulation of the air pressure within the piston cylinder. The top of the fixed sleeve 3043 is provided with an array of air holes corresponding to the air connection holes. The air hole array includes two or more air holes. The air extraction holes and air supply holes in the air connection holes are periodically connected with the air holes in the air hole array to realize air supply and extraction. This facilitates the formation of airflow to drive the turbine 30413 to rotate. It also realizes the reciprocating drive of the piston 30411.

[0047] In fact, the connecting frame 3041 includes a connecting ring and four vertical plates processed integrally with the connecting ring, and a connecting shell 3042 is installed on the top of the four vertical plates; Figure 7 The connecting frame 3041 is shown.

[0048] In practice, one air inlet hole can be eliminated and a separate pressure relief hole provided. Air can be supplied through the air inlet hole to keep the piston in an extended state, ensuring that the movable block 3045 can always press against the inner wall of the container. This structural design allows the inner support clamping portion 303 of the clamp 300 to directly cooperate with the force compensation portion 304, achieving force balance while clamping the container 200, thereby helping to improve the processing quality when flattening the container.

[0049] In this embodiment, the pump air pipeline includes an external connection hole 1013 opened on the side of the limit seat 101, a through hole 1012 on the top surface, a first pipe connected between the external connection hole 1013 and the through hole 1012, a cache cavity 1011 arranged on the bottom surface of the rotating disk 302, a transition cavity 3022 connected to the cache cavity 1011, a hollow channel connected to the transition cavity 3022 through the transition hole arranged on the connecting frame 3041, and an air outlet 30412 arranged on the connecting shell 3042, and the air outlet 30412 connects the hollow channel and the interior of the fixing sleeve 3043.

[0050] The external connection hole 1013 is used to connect to an air pump (not shown). The hollow channels are a first hollow channel 3048 and a second hollow channel 3049. The first hollow channel 3048 can be used as an air supply line, while the second hollow channel 3049 can be used as an air extraction line. In practice, both the first hollow channel 3048 and the second hollow channel 3049 can be used as air supply lines. The tops of the hollow channels are through-holes, but can be sealed with plugs 3047.

[0051] In practice, the limiting seat 101 is fixed, while the rotating disk 302 rotates, thus enabling gas transmission via a rotary joint. The rotary joint includes a docking ring 3023 mounted on the rotating disk 302. The docking ring 3023 is engaged within the transition chamber 3022 and can rotate within the transition chamber 3022. A gas connection terminal 3024 is mounted on the docking ring 3023, connecting the transition chamber 3022 to the perforation 1012. A limiting ring 3025 is provided within the transition chamber 3022 to limit the position of the docking ring 3023. The structure of the gas connection terminal 3024 is similar to that of a conventional gas nozzle. In this manner, air is supplied and extracted from the fixed sleeve 3043 via a pumping air pipeline, thereby utilizing the flowing high-pressure gas to drive the compensation block 3044. Furthermore, the force applied to the compensation block 3044 can be controlled by controlling the frequency of the pumping air, thereby facilitating better force balance and mitigating the deflection of the container caused by the rolling wheel 109 during rolling.

[0052] In some embodiments, as Figure 1As shown, a monitoring module 400 is also included. The monitoring module 400 is installed above the chassis 100. The monitoring module 400 is used to monitor the processing data of the container 200. The processing data at least includes the position information of the weld.

[0053] In this embodiment, the monitoring module 400 may include a camera and a line scan camera; the camera and line scan camera are mounted above the chassis 100 via a mounting bracket 401. The camera can capture images of the container 200 to facilitate image analysis of the container 200 model. The weld seam of the container 200 can then be preliminarily determined based on the signals from the container 200. The line scan camera can also acquire three-dimensional data of the container, which can then be further used to determine the weld seam of the container 200. The monitoring module 400 monitors the processing data of the container 200 and controls the feed of the servo moving member 107 accordingly. Furthermore, due to the different feed rates of the servo moving member 107, the force applied by the rolling wheel 109 to the container 200 also varies. Accordingly, the force applied by the rolling wheel 109 is balanced by the force compensating portion 304, which applies a pressing force to the inner wall of the container 200. This can reduce and prevent deviation of the container 200 during rotation and improve rolling quality. Furthermore, combined with the internal support clamping portion 303, high-precision processing of the container 200 is achieved.
