Description

Technical Field

[0001] The utility model belongs to the technical field of packaging carton production, and particularly relates to a deviation-correcting device for a roller conveyor used in carton production and transportation. Background Art

[0002] Cartons are the main packaging products used today. The basic material of cartons is corrugated cardboard, which is made into corrugated boxes by die-cutting, creasing, folding, stapling or gluing. The folding process in the production of packaging cartons is usually carried out by moving the blanks along parallel longitudinal beams with belts and drive rollers, and the lateral position can be adjusted according to the size of the carton.

[0003] In the existing folding production line, during the high-speed and continuous transmission of corrugated cardboard, the cardboard position is very likely to shift due to the physical properties of the material itself, the slight vibration of the conveyor belt or the improper adjustment of the guide mechanism. This shift not only destroys the stability of the corrugated cardboard on the transmission path, but also directly leads to the difficulty in maintaining consistent cardboard parallelism in the subsequent folding process, which in turn causes a series of problems.

[0004] When the corrugated cardboard fails to maintain precise parallel alignment, its edge or crease position may deviate after entering the folding area, resulting in defects such as uneven folding lines, twisted cardboard or incomplete folding. These problems not only affect the appearance of the carton, but more importantly, reduce the structural strength and sealing performance of the carton, resulting in a decline in the quality of the packaging carton products. Summary of the invention

[0005] In view of the problems existing in the prior art, the utility model provides a device for correcting the deviation of a roller conveyor used in the production and transportation of cartons. The differential operation of the double belts generates a lateral force component under the action of friction, so as to achieve real-time correction and stable transportation of the conveyed cardboard, and can detect and correct its position deviation in real time during the cardboard's forward movement. This dynamic adjustment method is more flexible and efficient than static correction.

[0006] The utility model is implemented as follows: a deviation correction device for a cartons production and transportation roller table comprises a conveying bracket, a transmission box is arranged at the end of the conveying bracket, a driving motor is arranged on the transmission box, a first driving pulley and a second driving pulley are arranged on the transmission box on the side where the driving motor is installed, and the driving motor drives the first driving pulley and the second driving pulley to rotate at a differential speed through a gear set in the transmission box;

[0007] A first conveyor belt is arranged on the upper end surface of the conveying bracket along the advancing direction of the corrugated cardboard, the driving side of the first conveyor belt is sleeved on the first active pulley, and a second conveyor belt is arranged above the first conveyor belt, a clamping space for the corrugated cardboard is formed between the upper belt of the first conveyor belt and the lower belt of the second conveyor belt, the driving side of the second conveyor belt is sleeved on the second active pulley, and the lower belt of the second conveyor belt transitions from a vertical state to a horizontal state along the advancing direction of the corrugated cardboard, and drives the corrugated cardboard forward and completes the bending operation under the clamping of the first conveyor belt and the second conveyor belt.

[0008] Furthermore, a fan is arranged outside the conveying bracket, and a plurality of adsorption ducts are arranged inside the conveying bracket along the length direction of the conveying bracket. The adsorption ducts are connected to the fan through a main pipe, and a plurality of first adsorption holes corresponding to the adsorption ducts are arranged on the upper end surface of the conveying bracket, and a plurality of second adsorption holes are arranged on the first conveying belt. Through the negative pressure generated by the fan, the air in the adsorption duct is drawn out to form a local low-pressure area. This low-pressure area acts on the corrugated cardboard through the first adsorption hole and the second adsorption hole to generate adsorption force, which effectively prevents the position of the cardboard from shifting during the conveying process. This design significantly improves the stability of the cardboard on the conveying bracket, providing a strong guarantee for the smooth progress of the subsequent folding process.

[0009] Furthermore, the plurality of first adsorption holes and the plurality of second adsorption holes are equidistantly distributed along the advancing direction of the corrugated cardboard.

[0010] Furthermore, the fan is provided with a dust removal hose, and the suction port of the dust removal hose is located above the clamping space, so that fine particles such as dust and paper scraps generated during the cardboard conveying and folding process can be captured and adsorbed in real time, thereby improving product quality.

[0011] Furthermore, a waste collection bucket is provided between the dust removal hose and the fan, and a conical filter is provided in the waste collection bucket, with the small diameter end of the conical filter facing the fan side. Dust, paper scraps and other waste materials discharged from the dust removal hose can be collected in a centralized manner. This design avoids further diffusion of waste materials in the air and improves dust removal efficiency; after being filtered by the conical filter, impurities in the airflow entering the fan are greatly reduced, thereby reducing the risk of wear of the fan blades and internal components due to long-term friction with impurities.

[0012] Furthermore, the suction side of the dust removal hose is connected to the box body through a clamp seat, and the clamp seat includes two semi-arc clamping parts, and the two semi-arc clamping parts are connected by a locking bolt, which can effectively prevent the dust removal hose from loosening or falling off due to vibration or external force during operation.

[0013] Furthermore, the conveying bracket is provided with a first roller and a second roller for tensioning the upper belt and the lower belt of the second conveying belt.

[0014] The utility model has the advantages and technical effects: Due to the adoption of the above technical solution, the differential operation of the double belts generates a lateral force component under the action of friction, so as to achieve real-time deviation correction and stable conveying of the conveyed cardboard, and can detect and correct its position deviation in real time during the cardboard's forward movement. This dynamic adjustment method is more flexible and efficient than static deviation correction. It reduces the downtime adjustment time caused by the position deviation of the cardboard, and improves the continuous operation capacity of the production line. At the same time, due to the improvement of folding accuracy, the generation of defective products is reduced, and the overall production efficiency and quality are further improved.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0022] like Figures 1 to 4 As shown, the present application provides a deviation correction device for a carton production and transportation roller, comprising a conveying bracket 1, a transmission box 2 is arranged at the end of the conveying bracket 1, a driving motor is arranged on the transmission box 2, and a first driving pulley 3 and a second driving pulley 4 are arranged on the transmission box 2 on the side where the driving motor is installed, and the driving motor drives the first driving pulley 3 and the second driving pulley 4 to rotate differentially through the gear set in the transmission box 2. Specifically, a plurality of groups of gears meshing with each other are arranged in the transmission box 2, and the power of the driving motor drives the large gear through the small gear on the input shaft of the transmission box 2 to achieve the purpose of deceleration. This deceleration is achieved by meshing gears with different numbers of teeth, wherein the small gear has a high rotation speed and the large gear has a low rotation speed, and the first driving pulley 3 and the second driving pulley 4 are respectively installed on gears with different numbers of teeth to achieve differential rotation.

[0023] The upper end surface of the conveying support 1 is provided with a first conveying belt 5 along the advancing direction of the corrugated cardboard, the driving side of the first conveying belt is sleeved on the first driving pulley, and a second conveying belt 6 is provided above the first conveying belt 5. Specifically, the conveying support 1 is provided with a first roller 13 and a second roller 14 for tensioning the upper belt and the lower belt of the second conveying belt 6. A clamping space for the corrugated cardboard is formed between the upper belt of the first conveying belt 5 and the lower belt of the second conveying belt 6, the driving side of the second conveying belt is sleeved on the second driving pulley, and the lower belt of the second conveying belt 6 transitions from a vertical state to a horizontal state along the advancing direction of the corrugated cardboard, and drives the corrugated cardboard forward and completes the bending operation under the clamping of the first conveying belt 5 and the second conveying belt 6.

[0024] Furthermore, a fan 7 is arranged outside the conveying bracket 1, and a plurality of adsorption air ducts 8 are arranged inside the conveying bracket 1 along the length direction of the conveying bracket 1. The adsorption air ducts 8 are connected to the fan 7 through the main pipe 9, and a plurality of first adsorption holes corresponding to the adsorption air ducts 8 are arranged on the upper end surface of the conveying bracket 1, and a plurality of second adsorption holes 5-1 are arranged on the first conveying belt 5. Through the negative pressure generated by the fan 7, the air in the adsorption air duct 8 is extracted to form a local low-pressure area. This low-pressure area acts on the corrugated cardboard through the first adsorption holes and the second adsorption holes 5-1, generating an adsorption force, which effectively prevents the position of the cardboard from shifting during the conveying process. This design significantly improves the stability of the cardboard on the conveying bracket 1, and provides a strong guarantee for the smooth progress of the subsequent folding process. Specifically, the plurality of the first adsorption holes and the plurality of the second adsorption holes 5-1 are equidistantly distributed along the forward direction of the corrugated cardboard.

[0025] Furthermore, a dust removal hose 10 is provided on the fan 7, and the suction port of the dust removal hose 10 is located above the clamping space. It can capture and adsorb fine particles such as dust and paper scraps generated during the cardboard conveying and folding process in real time, thereby improving product quality. Specifically, the adsorption side of the dust removal hose 10 is connected to the box body through a clamp seat 12, and the clamp seat 12 includes two semi-arc clamping parts, and the two semi-arc clamping parts are connected by a locking bolt. It can effectively prevent the dust removal hose 10 from loosening or falling off due to vibration or external force during operation.

[0026] Preferably, a waste collection barrel 11 is provided between the dust removal hose 10 and the fan 7, and a conical filter 15 is provided in the waste collection barrel 11, and the small diameter end of the conical filter 15 faces the fan 7 side. Specifically, the waste collection barrel 11 includes a barrel body and a barrel cover connected by threads, and the conical filter 15 is provided in the barrel body. The dust, paper scraps and other waste materials discharged from the dust removal hose 10 can be collected in a centralized manner. This design avoids further diffusion of waste materials in the air and improves dust removal efficiency; after being filtered by the conical filter 15, the impurities in the airflow entering the fan 7 are greatly reduced, thereby reducing the risk of wear of the fan 7 blades and internal components due to long-term friction with impurities.

[0027] Working principle: The driving sides of the first conveyor belt 5 and the second conveyor belt 6 are respectively sleeved on the first active pulley and the second active pulley, and the first active pulley and the second active pulley have different rotation speeds. The first conveyor belt 5 and the second conveyor belt 6 run at different speeds, thereby forming a speed difference between the two. Due to the existence of the speed difference, when the corrugated cardboard is clamped between the upper layer of the first conveyor belt 5 and the lower layer of the second conveyor belt 6, it will be subjected to the friction force of the different speeds of the two belts. When the corrugated cardboard is offset (such as deviating to one side), due to the relatively fast or slow speed of the belt on that side, a lateral force component pointing to the correct position will be generated. This force component will push the corrugated cardboard to move in the opposite direction, thereby correcting its offset.

[0028] Due to the adoption of the above technical solution, the differential operation of the double belts generates a lateral force component under the action of friction, so as to achieve real-time deviation correction and stable conveying of the conveyed cardboard, and can detect and correct its position deviation in real time during the cardboard's forward movement. This dynamic adjustment method is more flexible and efficient than static deviation correction. It reduces the downtime adjustment time caused by the position deviation of the cardboard and improves the continuous operation capacity of the production line. At the same time, due to the improvement of folding accuracy, the production of defective products is reduced, further improving the overall production efficiency and quality.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
