Description

Technical Field

[0001] The invention relates to the field of packaging box transportation, and more specifically, to a roller conveyor for packaging box processing. Background Art

[0002] Roller conveyor, also known as roller conveyor or roller conveyor, is a mechanical equipment that uses the rotation of rollers to transport items. In the field of packaging box processing, roller conveyors are mainly used to transport various packaging boxes, cartons and other items to achieve automated and continuous production processes. Roller conveyors are suitable for conveying items with flat bottoms, such as packaging boxes, cartons, etc. At the same time, it can withstand large impact loads and is suitable for conveying heavier items. Roller conveyors are mainly composed of transmission rollers, frames, brackets, drive devices and other parts. They have a simple structure and are easy to install and maintain.

[0003] In the process of packaging box processing, roller conveyors are widely used in automated production lines. For example, roller conveyors can play an important role in the transportation, sorting, and stacking of packaging boxes. By cooperating with other conveying equipment and special machines, the automated processing and transportation of packaging boxes can be realized, and production efficiency and product quality can be improved. Packaging boxes transported by roller conveyors will inevitably deviate when turning. Therefore, after the deviation occurs, it is necessary to check whether the counterweight rollers and other components inside the roller conveyor are faulty or worn. In the prior art, since paper packaging boxes are usually flattened and transported by roller conveyors during the production process, in order to improve the transportation efficiency of the packaging boxes, multiple packaging boxes are generally stacked together for transportation. However, when the stacked packaging box cardboards turn, the stacked packaging box cardboards will tilt due to inertia, causing the stacked packaging box cardboards to easily fall or tip over during subsequent transportation.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0022] See also Figures 1 to 8 A roller conveyor for packaging box processing comprises a roller conveyor body 1 and a material roller 101 rotatably connected to the inside of the roller conveyor body 1, a side plate 11 is fixedly connected to the upper side of the roller conveyor body 1, a control panel 12 is provided on the front of the roller conveyor body 1, and a material guide component 2 is provided on the upper side of the roller conveyor body 1; The material guiding component 2 includes a first slide groove 22 opened on the upper and lower sides of the front side of the horizontal part of the side plate 11, a first slider 221 is slidably connected inside the first slide groove 22, the front sides of the two first sliders 221 are commonly fixedly connected to the baffle 21, the back side of the first slider 221 is rotatably connected to the first roller 222, the right side of the baffle 21 is fixedly connected to the fixed plate 23, the right side of the fixed plate 23 is hinged to the rotating plate 231, guide holes 232 are opened through the left and right sides of the vertical part of the side plate 11, the right side of the rotating plate 231 is inserted into the guide hole 232, a driving member 24 is arranged on the back side of the horizontal part of the side plate 11, a sleeve 25 is fixedly connected to the back side of the baffle 21, and a counterweight plate 26 is slidably connected to the left side of the baffle 21.

[0023] The driving member 24 includes a servo motor 241, a screw rod 242 and a screw rod nut 243. The servo motor 241 is fixedly installed on the right rear part of the vertical part of the side plate 11. The right end of the screw rod 242 is fixedly connected to the output end of the servo motor 241. The screw rod nut 243 is threadedly connected to the outer side of the screw rod 242. The sleeve 25 is movably sleeved on the outer side of the screw rod nut 243. The sleeve 25 passes through the horizontal part of the side plate 11.

[0024] A height adjustment assembly 27 is provided on the upper side of the roller conveyor body 1 and on the left side of the baffle 21 .

[0025] By adopting the above technical solution, first, when the roller conveyor body 1 conveys the stacked materials through the material roller 101, before the stacked materials are sent from the horizontally arranged material roller 101 to the longitudinally arranged material roller 101, the stacked materials will first contact with the stacked materials and push the baffle 21 through the stacked materials. Through the control of the control panel 12, the roller conveyor body 1 will start the servo motor 241 of the driving part 24 to rotate with the screw 242, so that the screw 242 will drive the screw nut 243 on its outer side and the sleeve 25 on the outer side of the screw nut 243 to start moving to the right. The side plate 11 is fixed to the baffle plate 21, so that the baffle plate 21 will also move with it and always move with the stacked materials. When the baffle plate 21 moves to the right, the counterweight plate 26 on the left side of the baffle plate 21 will slowly move downward, and finally press the upper side of the stacked materials, and the counterweight plate 26 always moves with the baffle plate 21. At the same time, the back of the baffle plate 21 will slide in the first slide groove 22 through the first slider 221 and the first roller 222 that can roll inside the first slider 221, and the rotating plate 231 hinged to the fixed plate 23 will also slide in the guide groove under the push of the baffle plate 21. It should be noted that, because the shape of the rotating plate 231 is adapted to the guide groove, after the stacked materials push the baffle 21, if the baffle 21 tilts, the rotating plate 231 hinged to the fixed plate 23 will be restricted by the guide groove, and finally support one side of the baffle 21, so that the baffle 21 can still move freely. After the right side of the baffle 21 is in vertical contact with the side plate 11, the material suddenly stops moving during the movement process, and the inertia generated will drive the material to tilt toward the direction of the baffle 21. At this time, the baffle 21 can block the material. Since the stacked material is always in contact with the baffle 21 when turning, the baffle 21 can block the material when the material stops suddenly. At the same time, the counterweight plate 26 above the material will also press on the top of the material to prevent the material from tilting or falling due to inertia when it stops moving.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, a height adjustment assembly 27 is provided on the upper side of the roller conveyor body 1 and the left side of the baffle 21 . The height adjustment assembly 27 includes a second slide groove 271 opened at the front and rear parts of the left side of the baffle 21 .

[0027] A second slider 272 is slidably connected inside the second slide groove 271, and the left side of the second slider 272 is fixedly connected to the right side of the counterweight plate 26. A support seat 273 is fixedly connected to the left rear part of the upper end of the roller conveyor body 1, and the inclined surface of the support seat 273 faces the baffle 21, and the inclined surface of the support seat 273 begins to have an embedding groove 274. A support bar 275 is fixedly connected to the back of the counterweight plate 26, and the left side of the support bar 275 is provided with an inclined surface, and the inclined surface of the support bar 275 is rollingly connected to the second roller 276, and the lower side of the support bar 275 is in sliding contact with the upper side of the support seat 273. After the support bar 275 moves to the right, the inclined surface of the support bar 275 is in sliding contact with the inclined surface of the support seat 273. After the inclined surface of the support bar 275 contacts the inclined surface of the support seat 273, the second roller 276 rolls and contacts in the embedding groove 274.

[0028] Pressing components 28 are disposed inside and on both upper and lower sides of the counterweight plate 26 .

[0029] By adopting the above technical solution, first, when the baffle 21 moves to the right, the support bar 275 will move with the counterweight plate 26. At this time, the support bar 275 will gradually lose the support from the support seat 273, and at the same time, the second slider 272 fixed to the counterweight plate 26 will also slide in the second slide groove 271 on the left side of the baffle 21. As the baffle 21 continues to move to the right, the second roller 276 on the inclined surface of the support bar 275 will also roll in the embedded groove 274 on the inclined surface of the support seat 273, and gradually move downward. When the counterweight plate 26 and the pressing assembly 28 thereunder come into contact with the material, the counterweight plate 26 will stop moving downward. After the material is sent away by the longitudinally arranged rollers, the drive Component 24 will drive the baffle 21 to move to the left. At this time, the inclined surface of the support bar 275 contacts the inclined surface of the support seat 273, and the support bar 275 slides obliquely upward on the inclined surface of the support seat 273. When the lower side of the support bar 275 contacts the upper side of the support seat 273, the height of the support bar 275 will rise to the highest point. In the process of the stacked material pushing the baffle 21, the height of the counterweight block can be adjusted according to the material and the position of the support bar 275 on the inclined surface of the support seat 273, so that when the roller conveyor body 1 transports materials of different heights, it can still press the materials through the counterweight plate 26 and the pressing assembly 28 to ensure the stability of the stacked materials when turning.

[0030] like Figure 2 and Figure 6 As shown, the pressing assembly 28 includes an electric push rod 281 fixedly mounted on the upper side of the counterweight plate 26 , and the electric push rod 281 passes through the counterweight plate 26 .

[0031] The telescopic end of the electric push rod 281 is fixedly connected to a pressing plate 282, and the lower side of the pressing plate 282 is squeezed and contacted with an airbag 283. The upper left and right sides of the airbag 283 are fixedly connected to limit rods 284. The lower left and right sides of the counterweight plate 26 are provided with limit grooves 285. The limit rods 284 are slidably connected in the limit grooves 285. The upper inner side of the limit grooves 285 is fixedly installed with a first pressure sensor 286. The upper side of the airbag 283 is fixedly installed with an air pipe 287, and the air pipe 287 is connected to the airbag 283. The other end of the air pipe 287 is connected to an external air supply device.

[0032] A thickness detection assembly 29 is disposed on the front and inside of the support base 273 .

[0033] By adopting the above technical solution, when the counterweight plate 26 moves downward, the airbag 283 below it will first contact the upper side of the material. Because the limit rod 284 on the upper side of the airbag 283 can move up and down a certain distance in the limit groove 285, the airbag 283 contacts the material. The counterweight plate 26 sleeved on the outer side of the limit rod 284 through the limit groove 285 will continue to move downward. After the pressing plate 282 contacts the upper side of the airbag 283, the electric push rod 281 cooperates with the thickness detection component 29 to detect the material and then drives the pressing plate 282 to move. The pressing plate 282 squeezes the airbag 283, while the air pressure inside the airbag 283 is stable. At this time, the external air supply device will not convey gas into the airbag 283 through the conveying pipe. When transporting materials of the same volume, the same pressure will be maintained to press the upper side of the material. While the counterweight plate 26 presses the material, the pressing plate 282 will also press the airbag 283. Since the air pressure inside the airbag 283 is stable, the pressure of the airbag 283 when pressing the material remains stable, so as to avoid damage to the material due to excessive pressing pressure.

[0034] like Figures 2 to 4 As shown, a thickness detection assembly 29 is disposed on the front and inside of the support base 273 . The thickness detection assembly 29 includes a moving groove 291 disposed on the front of the support base 273 .

[0035] The movable groove 291 is internally slidably connected to a movable plate 292, the front side of the movable plate 292 is fixedly connected to a thin sheet 293, a slope is provided at the lower left side of the thin sheet 293, the upper side of the movable plate 292 is fixedly connected to a first pressure spring 294, the other end of the first pressure spring 294 is fixedly connected to an extrusion plate 295, and the second pressure sensor 296 is fixedly installed on the upper side of the interior of the movable groove 291, and the upper side of the extrusion plate 295 is in extrusion contact with the lower side of the second pressure sensor 296.

[0036] By adopting the above technical solution, first, in the process of the material roller 101 conveying the material, as the material passes through the thin sheet 293 fixed by the movable plate 292 on the side of the support seat 273, the thin sheet 293 will slide into the feeding of the lowest piece of material through its inclined surface close to the material side. When materials of different thicknesses are conveyed, the height to which the thin sheet 293 is lifted will change, and the upper side of the movable plate 292 is fixedly connected to the first pressure spring 294, and the extrusion plate 295 fixed to the top of the first pressure spring 294 is always in contact with the second pressure sensor 296. The lifted thin sheet 293 will drive the movable plate 292 to move upward and squeeze the first pressure spring 294, and the rebound force generated by the compression of the first pressure spring 294 will be fed back to the first pressure sensor 28 through the extrusion plate 295. 6, so that the first pressure sensor 286 transmits information to the control panel 12. At this time, the external air supply device will transport or extract the corresponding volume of gas into the conveying pipe according to the control of the control panel 12, so that the volume of the gas inside the airbag 283 changes. After the pressing plate 282 presses the airbag 283, due to the change in the volume of the gas inside the airbag 283, the pressure exerted on the material after the airbag 283 is squeezed will also change. Due to the different thicknesses of the materials, the squeezing force of the squeezing plate 295 on the second pressure sensor 296 will change, thereby controlling the volume of the gas inside the airbag 283, so that the pressure exerted on the material after the airbag 283 is squeezed can be adjusted accordingly according to the thickness of the material itself, so as to prevent the squeezing force from being too large or too small to affect the material conveying efficiency, and also to avoid damage to the material again.

[0037] like Figure 1 , Figure 7 and Figure 8 As shown, a cleaning component 3 is provided on the lower inner side of the roller conveyor body 1, and the cleaning component 3 includes a support plate 31 fixedly connected to the lower inner side of the roller conveyor body 1, a longitudinal linear array positioning guide rail 32 is fixedly connected to the upper side of the support plate 31, a positioning block 33 is slidably connected to the inner transverse linear array of the positioning guide rail 32, a scraper 34 is fixedly connected to the upper side of the positioning block 33, and a second pressure spring 35 is fixedly connected between the lower end of the positioning block 33 and the positioning guide rail 32.

[0038] By adopting the above technical solution, first, during the rolling of the material roller 101, the positioning block 33 inside the positioning guide rail 32 is always pushed upward by the second pressure spring 35, so that the scraper 34 above the positioning block 33 contacts the material roller 101. As the material roller 101 starts to rotate, the impurities originally attached to the surface of the material roller 101 will be scraped off by the scraper 34. Since the material roller 101 is always in contact with the scraper 34 during the rotation process, the scraper 34 can clean the impurities attached to the surface of the material roller 101 to avoid corrosion of the roller caused by impurities attached to the surface of the roller, and at the same time prevent the bulge caused by the attachment of impurities to the surface of the roller from causing the material to deviate during the transportation process, which not only ensures the cleanliness of the roller surface, but also ensures the transportation efficiency of the material.

[0039] like Figure 8 As shown, a monitoring component 36 is provided inside the support plate 31, and the monitoring component 36 includes an insertion slot 361 that is formed in a horizontal linear array and runs through the top of the inner wall at the rear end of the positioning guide rail 32. A card plate 362 is inserted inside the insertion slot 361, and a trigger plate 363 is fixedly connected to the back of a single horizontal card plate 362. After the positioning block 33 moves upward, it is squeezed and contacted with the inclined surface of the card plate 362, and the left and right sides of the rear end of the trigger plate 363 are fixedly connected to third pressure springs 364. The left and right sides of the inside of the support plate 31 are provided with third pressure sensors 365 in a longitudinal linear array, and the other end of the third pressure spring 364 is sleeved on the outside of the third pressure sensor 365. After the positioning block 33 squeezes the card plate 362, the trigger plate 363 is squeezed and contacted with the third pressure sensor 365, and the two corresponding third pressure sensors 365 on the left and right are fixedly installed on the left and right sides of the back of the corresponding positioning guide rail 32.

[0040] By adopting the above technical solution, first, after the scraper 34 contacts the material roller 101, if the surface of the roller is worn, the second pressure spring 35 under the positioning block 33 will push the positioning, and the positioning block 33 will slide upward inside the positioning guide rail 32, and will also contact the inclined surface of the card plate 362 entering the insertion groove 361. The card plate 362 squeezed by the positioning block 33 will move toward the direction of the third pressure sensor 365, and push the trigger plate 363 to squeeze the third sensor. Then the control panel 12 electrically connected to the third pressure sensor 365 will issue a warning. When the trigger plate 363 needs to be reset, the third pressure spring 364 will push it. Because after the roller is worn, the positioning block 33 at the corresponding position will start to move upward and push the trigger plate 363 to squeeze the second sensor, so that the control panel 12 can quickly display the worn roller, which is convenient for the subsequent maintenance and repair of the roller conveyor body 1, and the conveying efficiency of the roller conveyor body 1 for materials will also be guaranteed.

[0041] Working principle: First, when the roller conveyor body 1 conveys the stacked materials through the material roller 101, as the materials pass through the thin sheet 293, the thin sheet 293 will slide into the feeding of the lowest piece of material through its inclined surface close to the material side. When materials of different thicknesses are conveyed, the height of the thin sheet 293 being lifted will change, and the lifted thin sheet 293 will drive the moving plate 292 to move upward in the moving groove 291 and squeeze the first pressure spring 294. The rebound force generated by the compression of the first pressure spring 294 will be fed back to the first pressure sensor 286 through the squeezing plate 295, so that the first pressure sensor 286 transmits information to the control panel 12. At this time, the external air supply device will supply air to the inside of the conveying pipe according to the control of the control panel 12. The corresponding volume of gas is delivered or extracted, so that the volume of gas inside the airbag 283 changes. After the pressing plate 282 presses the airbag 283, the volume of gas inside the airbag 283 changes, and the pressure of the airbag 283 on the material after being squeezed will also change. As the material contacts the baffle 21, the baffle 21 will be pushed. Then the control panel 12 controls the roller conveyor body 1 to start the driving part 24, and the servo motor 241 with the screw 242 rotates, so that the screw 242 will drive the screw nut 243 outside it and the sleeve 25 outside the screw nut 243 to start moving to the right. At the same time, the back of the baffle 21 will pass through the first slider 221 and the first roller 222 that can roll inside the first slider 221 in the first slide 22. The rotating plate 231 hinged to the fixed plate 23 will also slide in the guide groove under the push of the baffle 21. Because the sleeve 25 passes through the side plate 11 and is fixed to the baffle 21, the baffle 21 will also move with it. In the process of the baffle 21 moving to the right, the support bar 275 will move with the counterweight plate 26. At this time, the support bar 275 will gradually lose the support from the support seat 273. At the same time, the second slider 272 fixed to the counterweight plate 26 will also slide in the second slide groove 271 on the left side of the baffle 21. As the baffle 21 continues to move to the right, the second roller 276 on the inclined surface of the support bar 275 will also roll in the embedded groove 274 on the inclined surface of the support seat 273, and gradually move downward. When the counterweight plate 26 and the pressing assembly 28 thereunder are After the material contacts, the counterweight plate 26 will stop moving downward, and when the counterweight plate 26 moves downward, the airbag 283 below it will first contact the upper side of the material, because the limit rod 284 on the upper side of the airbag 283 can move up and down at an end distance in the limit groove 285, so that the airbag 283 contacts the material, and the counterweight plate 26 sleeved on the outer side of the limit rod 284 through the limit groove 285 will continue to move downward. After the pressing plate 282 contacts the upper side of the airbag 283, the electric push rod 281 cooperates with the thickness detection component 29 to detect the material and then drives the pressing plate 282 to move, so that the pressing plate 282 squeezes the airbag 283, and the internal air pressure of the airbag 283 is stable. At this time, the external air supply equipment will not convey gas into the airbag 283 through the conveying pipe.When transporting materials of the same volume, the same pressure will be maintained to press the upper side of the materials. When the materials suddenly stop moving during the movement, the inertia generated will drive the materials to tilt toward the baffle 21. At this time, the baffle 21 can block the materials. After the materials are sent away by the longitudinally arranged rollers, the driving member 24 will drive the baffle 21 to move to the left. At this time, the inclined surface of the support bar 275 contacts the inclined surface of the support seat 273, and the support bar 275 slides obliquely upward on the inclined surface of the support seat 273. When the lower side of the support bar 275 contacts the upper side of the support seat 273, the height of the support bar 275 will rise to the highest point. During the rolling process of the material roller 101, the positioning block 33 inside the positioning guide rail 32 is always pushed upward by the second pressure spring 35, so that the positioning The scraper 34 above the block 33 contacts the material roller 101. As the material roller 101 starts to rotate, the impurities originally attached to the surface of the material roller 101 will be scraped off by the scraper 34. If the roller surface is worn, the second pressure spring 35 below the positioning block 33 will push the positioning. While the positioning block 33 slides upward inside the positioning guide rail 32, it will also contact the inclined surface of the card plate 362 entering the insertion groove 361. The card plate 362 squeezed by the positioning block 33 will move toward the direction of the third pressure sensor 365 and push the trigger plate 363 to squeeze the third sensor. Then the control panel 12 electrically connected to the third pressure sensor 365 will issue a warning. When the trigger plate 363 needs to be reset, the third pressure spring 364 will push it.
