Description

Technical Field

[0001] This utility model relates to the field of cardboard box production equipment technology, specifically to a cardboard box feeding guide mechanism on a secondary waste removal device. Background Technology

[0002] Waste removal is an indispensable part of the cardboard box production process. Traditional waste removal methods often rely on manual operation, which is not only inefficient but also poses safety hazards. With the continuous development of automation technology, more and more cardboard box manufacturers are adopting automated waste removal devices to improve production efficiency and product quality.

[0003] Currently, there are various waste removal devices on the market, but existing cardboard box waste removal devices still have some shortcomings in terms of pressing and feeding cardboard boxes. For example, a cardboard box production line disclosed in Chinese utility model patent application number 202020660954.6, in which cardboard boxes are pushed into the conveying mechanism by a pushing mechanism, and under the action of a blower pump, an air blowing cover continuously blows air to clean up waste. Therefore, when the cardboard boxes enter the conveying mechanism from the pushing mechanism, they may be affected by the air blown out by the air blowing cover, resulting in displacement, falling, or being overturned, which will affect the feeding of cardboard boxes and even affect subsequent production processes. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a cardboard box feeding guide mechanism for a secondary waste cleaning device.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A cardboard box feeding guide mechanism for a secondary waste removal device includes two sets of symmetrically arranged support side plates, and a guide pressing assembly and a blowing assembly installed between the two support side plates. The two sets of support side plates are movably installed on the support beam at the top of the conveyor frame. The blowing assembly is located behind the guide pressing assembly. The guide pressing assembly includes support rods fixed at both ends to the two support side plates, multiple guide frames rotatably sleeved on the support rods, and pressure rollers rotatably installed at the bottom of the guide frames. After installation, the guide frames are inclined backward and supported by the pressure rollers at their ends. The front side of the guide frames forms a downwardly inclined guide surface.

[0007] Furthermore, the multiple guide frames are arranged at even intervals along the support rod.

[0008] In this utility model, the guide frame includes a bushing for being sleeved on a support rod, a guide rod connected to the top of the bushing, and a connecting seat connected to the bottom of the guide rod. The guide rod has a rectangular tubular structure, and the bushing and the connecting seat are both located on the rear side of the guide rod. The front side of the guide rod is smoothly arranged to form the guide surface.

[0009] Furthermore, a locking sleeve is provided on one side of the bushing on the support rod. The locking sleeve is provided with a limiting block extending axially and a handle with a radial thread engagement. The locking sleeve is tightened and fixed to the support rod by the handle. A limiting pin is provided at the end of the limiting block corresponding to the width position of the bushing. The limiting pin abuts against the end face of the bushing. The locking sleeve and the limiting pin limit the bushing axially.

[0010] In this utility model, the top of the support beam is provided with a support guide rail extending along the conveying direction, and the bottom of the two side support plates is provided with guide wheels that roll on the support guide rail. The guide wheels drive the support side plates to move along the support guide rail.

[0011] Furthermore, the two supporting side plates are also provided with a drive assembly for driving the guide wheel to rotate. The drive assembly includes a rotating seat fixed to the outside of the two supporting side plates, a driven shaft with both ends rotatably engaged on the rotating seat, a first sprocket mounted on the driven shaft, and a second sprocket mounted on the guide wheel. One end of the driven shaft extends outward and has a handwheel for driving the driven shaft to rotate at the extended end. The first sprocket has two sets and is respectively located on the inside of the driven shaft near the supporting side plate. The first sprocket and the second sprocket are connected by a chain. When the handwheel is turned, the driven shaft drives the guide wheel on the two supporting side plates to rotate through the first sprocket.

[0012] Furthermore, the rolling surface of the guide wheel is concave, and the concave guide wheel is adapted to the top surface of the supporting guide rail.

[0013] Furthermore, the lower part of the support side plate is provided with a limiting roller, the shaft of the limiting roller is rotatably engaged with the support side plate, the limiting roller abuts against the bottom of the support beam and cooperates with the guide wheel to form upper and lower limits.

[0014] This utility model has the following advantages and beneficial effects:

[0015] A guide and clamping assembly is installed at the feeding end of the conveyor frame. The guide frame in the guide and clamping assembly is inclined backward and supported by the pressure roller at the end, so that the front side of the guide frame forms a downward inclined guide surface. When the cardboard box that has undergone the first waste removal enters the secondary waste removal device, the front end of the cardboard box will hit the guide surface and thus deflect downward, so that the cardboard box can fall quickly onto the conveyor frame. Once on the conveyor frame, the cardboard box is clamped by the pressure roller, which prevents it from being blown off course, falling, or overturned by the air blowing assembly during the feeding process. This ensures that the cardboard box is fed normally for secondary waste removal and ensures the normal operation of the subsequent production process. Attached Figure Description

[0025] like Figures 1 to 5As shown, this embodiment discloses a carton feeding and guiding mechanism on a secondary waste removal device. The secondary waste removal device includes a conveyor frame 1 for transporting cartons. The carton feeding and guiding mechanism 2 is movably mounted on a support beam 11 at the top of the conveyor frame 1 and is located at the feeding end of the conveyor frame 1. The conveyor frame 1 uses a conveyor belt to transport cartons. The conveyor belt is driven by a drive motor. Specifically, two rotating shafts are installed parallel to each other on the support beam 11. The conveyor belt is fitted onto the two rotating shafts, and the drive motor drives one of the rotating shafts to rotate, thereby transporting the cartons. The carton feeding and guiding mechanism 2 includes two sets of symmetrically arranged support side plates 20, and a guide pressing assembly 21 and a blowing assembly 22 installed between the two support side plates 20. The blowing assembly 22 is located behind the guide pressing assembly 21. The cartons passing through the guide pressing assembly 21 are blown by the blowing assembly 22 to achieve the effect of secondary waste removal. Component 21 includes a support rod 23 fixed at both ends to the two side support plates 20, multiple guide frames 24 rotatably sleeved on the support rod 23, and pressure rollers 25 rotatably installed at the bottom of the guide frames 24. The multiple guide frames 24 are evenly spaced along the support rod 23. The length of the guide frame 24 is greater than the height of the support rod 23. Therefore, after installation, the guide frame 24 will tilt backward and form support through the pressure rollers 25 at the end. Specifically, the front side of the guide frame 24 forms a downwardly inclined guide surface 240. When the cardboard box that has undergone the first waste removal enters the secondary waste removal device, the front end of the cardboard box will hit the guide surface 240 and thus shift downward, so that the cardboard box can quickly fall into the conveyor frame 1. The cardboard box that falls into the conveyor frame 1 is pressed by the pressure rollers 25 to prevent it from being blown off course, falling, or overturned by the air blowing component 22 during the feeding process. This ensures that the cardboard box is fed normally for secondary waste removal and ensures the normal operation of the subsequent production process.

[0026] Specifically, the blowing assembly 22 includes an air collecting pipe 221 and multiple air outlet pipes 222 connected to the air collecting pipe 221. The multiple air outlet pipes 222 are arranged corresponding to the guide frame 24. The input end of the air collecting pipe 221 is connected to a blower. The air outlet pipes 222 blow air towards both sides of the guide frame 24, thereby performing secondary waste removal on the cardboard box.

[0027] In this embodiment, the guide frame 24 includes a bushing 241 for sleeved on the support rod 23, a guide rod 242 connected to the top of the bushing 241, and a connecting seat 243 connected to the bottom of the guide rod 242. Preferably, the bushing 241 and the connecting seat 243 are connected to the guide rod 242 by welding. Specifically, the guide rod 242 has a rectangular tubular structure, and the bushing 241 and the connecting seat 243 are both located on the rear side of the guide rod 242. The front side of the guide rod 242 is smoothly arranged to form the guide surface 240.

[0028] Furthermore, since the guide frame 24 is rotatably sleeved on the support rod 23, it is necessary to axially limit the guide frame 24. A locking sleeve 26 is provided on the support rod 23 on one side of the bushing 241. The locking sleeve 26 is provided with a limiting block 261 extending axially and a handle 262 with radial thread engagement. The locking sleeve 26 is tightened and fixed on the support rod 23 by the handle 262. A limiting pin 263 is provided at the end of the limiting block 261 corresponding to the width position of the bushing 241. The limiting pin 263 abuts against the end face of the bushing 241. Thus, the locking sleeve 26 and the limiting pin 263 cooperate to achieve axial limitation of the bushing 241. When it is necessary to change the position of the guide frame 24, it is only necessary to loosen the handle 262 to allow the locking sleeve 26 and the support rod 23 to move relative to each other for adjustment.

[0029] In this embodiment, during waste removal, in order to remove waste from cartons of different specifications, it is necessary to adjust the distance between the guide pressing assembly 21 and the feeding port. Therefore, a support guide rail 12 extending along the conveying direction is provided on the top of the support beam 11 on the conveying frame 1, and guide wheels 27 that roll on the support guide rail 12 are provided below the support side plates 20 on both sides. The support side plates 20 can be moved along the support guide rail 12 by the guide wheels 27, thereby adjusting the position of the support side plates 20.

[0030] Furthermore, to facilitate the adjustment of the position of the support side plates 20, a drive assembly 28 is provided on both sides of the support side plates 20. The drive assembly 28 includes a rotating seat 281 fixed to the outside of the two support side plates 20, a driven shaft 282 rotatably engaged with the rotating seat 281 at both ends, a first sprocket 283 mounted on the driven shaft 282, and a second sprocket 284 mounted on the guide wheel 27. Specifically, one end of the driven shaft 282 extends outward, and a handwheel 285 is provided at the extended end to facilitate the rotation of the driven shaft 282. Two sets of the first sprocket 283 are provided and respectively located on the inner side of the driven shaft 282 near the support side plate 20. The first sprocket 283 and the second sprocket 284 are connected by a chain. The chain is a conventional component and is not shown in the figure. When the handwheel 285 is rotated, the driven shaft 282 can drive the guide wheel 27 on both sides of the support side plates 20 simultaneously, making it more convenient to adjust the position of the support side plates 20. Preferably, in order to enable the guide wheel 27 to roll along the support rail 12, the rolling surface of the guide wheel 27 is set as a concave structure, and the concave structure of the guide wheel 27 is adapted to the support rail 12.

[0031] Furthermore, in order to prevent the support side plate 20 from detaching from the conveyor frame 1, a limiting roller 29 is provided at the lower part of the support side plate 20. The rotating shaft of the limiting roller 29 is rotatably engaged with the support side plate 20. The limiting roller 29 abuts against the bottom of the support beam 11 on the conveyor frame 1 to form upper and lower limits, thereby preventing the guide wheel 27 from detaching from the support guide rail 12.

[0032] The above description in this specification is merely an illustrative example of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the specific embodiments described or adopt similar methods to replace them, as long as they do not deviate from the content of this specification or exceed the scope defined in the claims, they shall all fall within the protection scope of this invention.
