Description

Technical Field

[0001] The present application relates to the technical field of automatic material processing equipment, and in particular to a material bag rolling and shaping device capable of rolling and shaping material bags of different specifications. Background Art

[0002] In automatic conveyor lines, roller-forming of material bags can make the shape of the material bags more regular and compact, making them more stable and firm during subsequent packaging, stacking and transportation, reducing the risk of deformation and scattering, and improving packaging quality. The shaped material bags are easier to transport on the conveyor line, which can reduce problems such as jamming, tipping and blockage, and improve the operating efficiency and reliability of the conveyor line. In addition, through roller-forming, the volume of the material bags can be compressed so that they take up less space during storage and transportation, thereby reducing warehousing and logistics costs.

[0003] Chinese utility model patent CN202122676182.2 discloses a material bag leveling device, including: a conveyor line, a lifting unit, a bracket, and an upper leveling unit. The lifting unit is installed on the conveyor line. The lifting unit has an output end that moves in a straight line. The bracket is arranged above the conveyor line and installed at the output end. The lifting unit is used to control the height of the bracket. The upper leveling unit includes: a pressure roller and a position adjustment assembly. The pressure roller is a cylindrical roller. The pressure roller is located directly above the conveyor line and installed on the bracket. The position adjustment assembly is arranged between the bracket and the pressure roller. The pressure roller is rotatably installed on the position adjustment assembly. The position adjustment assembly is used to adjust the distance between the pressure roller and the conveyor line.

[0004] Although the technical solution disclosed in the above document squeezes the upper surface of the material bag by a pressure roller so that the locally accumulated particles can move toward other positions in the packaging bag, thereby shaping the material bag, its application process requires turning a hand wheel to adjust the position of the pressure roller, which is inconvenient to use.

[0005] Therefore, the existing automatic conveyor line material bag roller shaping machine still has the following problems in practical application: 1. In order to adapt to material bags of different height specifications, the roller shaping machine needs to be adjusted in height, and the existing roller shaping machine uses a rotating hand wheel and a lead screw to adjust the height. When adjusting, the operator needs to turn the hand wheel to drive the lead screw and then drive the roller to rise or fall. This manual adjustment method is inconvenient to operate and relies on manual labor, which increases the labor cost in the production process; 2. The shaping components of the existing roller shaping machines mostly adopt a single roller component and a conveying component in parallel design, which is less suitable for irregular material bags.

[0006] Therefore, the existing automatic conveyor line material bag roller pressing and shaping machine still has many defects, and it is necessary to propose a new technical solution to solve the problems existing in the prior art. Utility Model Content

[0035] The present application is further described below in detail through specific embodiments in conjunction with the accompanying drawings.

[0036] In the description of this application: unless otherwise specified, the meaning of "plurality" is two or more. The terms "first", "second", "third", etc. in this application are intended to distinguish the objects referred to, and do not have special meanings in terms of technical connotations (for example, they should not be understood as emphasizing the importance or order, etc.). Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).

[0037] The terms such as "upper", "lower", "left", "right", "middle", etc. used in this application are usually used to facilitate intuitive understanding by comparing with the accompanying drawings, and are not absolute limitations on the positional relationship in the actual product. Without departing from the technical concept disclosed in this application, changes in these relative positional relationships should also be regarded as the scope of this application.

[0038] The present embodiment provides a material bag rolling and shaping device, which can roll and shape material bags on automatic conveyor lines. In order to adapt to material bags of different height specifications, the present application adopts a motor-driven lead screw lifting method to achieve the lifting and lowering adjustment of the rolling roller assembly. For example, by lifting the lead screw driven by the lifting motor, the height of the rolling roller assembly is raised when the lifting motor rotates forward, and the height of the rolling roller assembly is lowered when the lifting motor rotates reversely. In order to improve the adaptability of the material bag rolling and shaping device to irregular material bags with complex and uncertain initial states, the present application adopts a multi-stage roller series connection method to shape the material bags. In the present embodiment, a four-stage roller series connection method is adopted, and the four-stage rollers are connected in series using a chain drive method. Through the steps of pre-shaping, shaping, and final shaping, the shaping of material bags in complex states is achieved. The structural principle of the material bag rolling and shaping device provided by the present application is described in detail below in conjunction with the accompanying drawings.

[0039] See also Figure 1 , 2The present application provides a material bag rolling and shaping device, which mainly includes a material bag conveying part 1 and a rolling part 2 arranged above the material bag conveying part 1. The material bag conveying part 1 includes a conveying frame 11 and a conveyor belt 12 installed on the conveying frame 11. The conveyor belt 12 conveys several material bags to the bottom of the rolling part 2 in sequence, and then outputs the material bags after the rolling shaping is completed. The conveying part in the present application mainly plays the role of conveying the material bags, and it can be any mechanism that can convey materials.

[0040] The rolling part 2 mainly includes a rolling mounting frame 21 mounted above the conveying frame 11. The rolling mounting frame 21 is straddled on the conveying frame 11. The rolling mounting frame 21 is a steel structure frame, which mainly provides an installation position for subsequent mechanisms and components.

[0041] A lifting assembly 22 is disposed on the top of the rolling mounting frame 21 , and a power output end of the lifting assembly 22 is connected to the rolling roller assembly 23 . The lifting assembly 22 can drive the rolling roller assembly 23 to rise or fall.

[0042] See also Figure 1 The lifting assembly 22 in the present application mainly includes a lifting motor 221 and a motor mounting frame 222 for mounting the lifting motor 221 . The motor mounting frame 222 is connected to the roller mounting frame 21 through a vertical mounting tube 223 . The vertical mounting tube 223 is arranged below the motor mounting frame 222 .

[0043] In this embodiment, the output end of the lifting motor 221 is connected to a vertically arranged lead screw 224, which is arranged in a vertical installation cylinder 223, and a nut 225 is arranged on the lead screw 224. A connecting cylinder 226 is arranged below the nut 225. The connecting cylinder 226 is an annular cover arranged around the outer periphery of the lead screw 224. The outer wall of the connecting cylinder 226 is slidably connected to the inner wall of the vertical installation cylinder 223. A slider is arranged on the outer wall of the connecting cylinder 226, and a vertical slide groove adapted to the slider is arranged on the inner wall of the vertical installation cylinder 223; a guide ring sleeve 227 is arranged on the inner wall of the connecting cylinder 226, and a guide through hole is provided on the guide ring sleeve 227 to allow the lead screw 224 to pass through, and the bottom of the connecting cylinder 226 is connected to the rolling roller assembly 23. In order to achieve height limiting, an ascending stopper 228 and a descending stopper are arranged on the lead screw 224, and the guide ring sleeve 227 is arranged between the ascending stopper 228 and the descending stopper.

[0044] When the lead screw 224 rotates along the first rotation direction (for example, clockwise) under the drive of the lifting motor 221, the nut 225 and the connecting tube 226 move downward along the central axis direction of the lead screw 224, driving the rolling roller assembly 23 to descend. When the guide ring sleeve 227 abuts against the descending baffle plate 228, it means that the rolling roller assembly 23 has dropped to the lowest position, and the descending baffle plate limits the rolling roller assembly 23 from further descending, thereby achieving automatic stop in place; when the lead screw 224 rotates along the second rotation direction (counterclockwise) under the drive of the lifting motor 221, the nut 225 and the connecting tube 226 move upward along the central axis direction of the lead screw 224, driving the rolling roller assembly 23 to rise. When the guide ring sleeve 227 abuts against the ascending baffle plate 228, it means that the rolling roller assembly 23 has risen to the highest position, and the ascending baffle plate 228 limits the rolling roller assembly 23 from further rising, thereby achieving automatic stop in place.

[0045] Of course, in other embodiments, the lifting assembly 22 in the present application may also adopt some linear drive actuators on the market, such as: driving electric cylinder, hydraulic linear drive, pneumatic linear drive, etc.

[0046] In this application, see Figure 1 The rolling roller assembly 23 installed on the rolling mounting frame 21 includes: a rolling motor 231, a driving wheel installed on the output shaft of the rolling motor 231, a first transmission wheel 232 meshing with the driving wheel for transmission, and a second transmission wheel 234 and a third transmission wheel 235 linked to the first transmission wheel 232 through a driving chain 233, wherein: the first rolling roller 2311 is installed on the second transmission wheel 234, the second rolling roller 2312 is installed on the third transmission wheel 235, the second transmission wheel 234 is connected to the first passive rolling roller 2310 through the first transmission chain 238, and the third transmission wheel 235 is connected to the third rolling roller 2313 through the second transmission chain 239.

The first fixing plate 2315 and the second fixing plate 2316 are arranged opposite to each other, and the rolling motor 231 is installed on the first fixing plate 2315; the first transmission wheel 232, the second transmission wheel 234 and the third transmission wheel 235 are arranged in a triangle shape, and the first transmission wheel 232, the second transmission wheel 234 and the third transmission wheel 235 are arranged in a triangle shape. A transmission wheel 232 is located above the second transmission wheel 234 and the third transmission wheel 235; the second transmission wheel 234 is a double-stage sprocket, the first-stage sprocket on the second transmission wheel 234 is connected to the drive chain 233, and the second-stage sprocket on the second transmission wheel 234 is connected to the first transmission chain 238; the third transmission wheel 235 is a double-stage sprocket, the first-stage sprocket on the third transmission wheel 235 is connected to the drive chain 233, and the second-stage sprocket on the third transmission wheel 235 is connected to the second transmission chain 239.

[0048] In this embodiment, the first rolling roller 2311 is coaxially arranged with the second transmission wheel 234, one end of the first rolling roller 2311 is rotatably connected to the first fixed plate 2315, and the other end of the first rolling roller 2311 is rotatably connected to the second fixed plate 2316; the second rolling roller 2312 is coaxially arranged with the third transmission wheel 235, one end of the second rolling roller 2312 is rotatably connected to the first fixed plate 2315, and the other end of the second rolling roller 2312 is rotatably connected to the second fixed plate 2316. Figure 3 .

[0049] In this embodiment, the first passive rolling roller 2310 is arranged on the fourth transmission wheel 236, the first passive rolling roller 2310 is coaxially arranged with the fourth transmission wheel 236, the fourth transmission wheel 236 is transmission-connected to the second transmission wheel 234 through the first transmission chain 238, one end of the first passive rolling roller 2310 is rotationally connected to the first fixed plate 2315, and the other end of the first passive rolling roller 2310 is rotationally connected to the second fixed plate 2316; the third rolling roller 2313 is arranged on the fifth transmission wheel 237, the third rolling roller 2313 is coaxially arranged with the fifth transmission wheel 237, the fifth transmission wheel 237 is transmission-connected to the third transmission wheel 235 through the second transmission chain 239, one end of the third rolling roller 2313 is rotationally connected to the first fixed plate 2315, and the other end of the third rolling roller 2313 is rotationally connected to the second fixed plate 2316.

[0050] In this embodiment, the line connecting the center of the first passive roller 2310 and the center of the first roller 2311 forms an angle of 14° with the horizontal plane, the vertical height of the first passive roller 2310 is higher than the vertical height of the first roller 2311, the bottom surface of the first passive roller 2310 is higher than the bottom surface of the first roller 2311, the bottom surface of the first roller 2311 is lower than the bottom surface of the second roller 2312, and the bottom surface of the second roller 2312 is The surface is basically flush with the bottom surface of the third rolling roller 2313, the material bag is pre-shaped between the first passive rolling roller 2310 and the first rolling roller 2311, shaped between the first rolling roller 2311 and the second rolling roller 2312, and finally shaped between the bottom surface of the second rolling roller 2312 and the third rolling roller 2313. Therefore, the device provided in the present application realizes the gradual shaping of irregular material bags through the structural form of multi-stage series rolling rollers.

[0051] Of course, in other embodiments, the rolling roller assembly 23 in the present application may also include more than four rolling rollers, and more levels of rolling rollers may be connected in series to achieve more sophisticated rolling shaping.

[0052] In other embodiments, a line connecting the center of the first passive rolling roller 2310 and the center of the first rolling roller 2311 forms a certain angle with the horizontal plane, and the angle can be selected and adapted according to specific needs.

[0053] Therefore, the structural principle of a material bag rolling and shaping device provided by the present application is as follows: the lifting motor in the lifting assembly drives the lead screw, and the lead screw drives the rolling roller assembly to lift or lower by rotating with the nut. The upper and lower limits are controlled by the baffle. During the rising and lowering process, the lead screw always passes through the guide ring sleeve, and the guide ring sleeve provides a guiding function. The start and stop of the lifting motor are manually operated by the operating button, which is simple and convenient. The rolling motor in the material bag rolling and shaping device drives the driving chain to drive the first passive rolling roller, and the linkage transmission chain drives the first rolling roller, the second rolling roller and the third rolling roller to operate to realize the rolling shaping of the material bag. Among them, the first passive rolling roller forms a certain angle with the other three groups of rolling rollers, so that the material bag can enter the rolling process from the front end more smoothly. The material bag rolling and shaping device provided by the present application can be suitable for material bags of different specifications, has strong adaptability, and the structure of the device is simple and reliable, and it is easy to use.

[0054] Therefore, the present application provides a material bag rolling and shaping device, which drives the rolling roller assembly to rise or fall through a lifting assembly, which is easy to operate and adjust, so that the device can adapt to material bags of different height specifications. At the same time, the rolling roller assembly includes four rolling rollers, namely a first rolling roller, a second rolling roller, a third rolling roller and a first passive rolling roller. The four rolling rollers are parallel to each other, and each rolling roller is perpendicular to the length direction of the conveyor belt of the material bag conveying part. Along the material bag conveying direction, the four rolling rollers are connected in series through a transmission chain and a transmission wheel. The material bag is pre-shaped, shaped and finally shaped by the four rolling rollers. Compared with the traditional single roller assembly, the arrangement of the four rolling rollers can adapt to the rolling of irregular material bags, thereby improving the adaptability of the material bag rolling and shaping device to irregular material bags with complex and uncertain initial states.

[0055] In the present application, the first passive roller, the first roller, the second roller and the third roller are arranged in sequence to form a multi-stage series connection. When the material bag is conveyed to the bottom of the roller assembly, the first passive roller and the first roller first pre-shape the material bag, and then the second roller and the third roller shape and finally shape the material bag in sequence. The shaped material bag is output from the bottom of the roller assembly via the conveyor belt. Therefore, the device provided by the present application realizes the gradual shaping of irregular material bags through the structural form of multi-stage series rollers. Since the line connecting the center of the first passive roller and the center of the first roller forms a certain angle with the horizontal plane, and the vertical height of the first passive roller is higher than that of the first roller, when the material bag enters the bottom of the roller assembly, the first passive roller can adapt to the height of the material bag first, and roll the material bag to a height that the subsequent rollers can adapt to, thereby ensuring the smooth and sequential rolling action.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.

[0057] The above is a relatively specific and detailed description of the present application through general description and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not deviate from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the scope of protection of the claims of the present application.
