Description

Technical Field

[0001] The invention relates to the technical field of packaging bag production and manufacturing equipment, in particular to a feeding and conveying mechanism of a bag sorting machine. Background Art

[0002] After the packaging bags are manufactured in the bag making machine, there is generally a conveying and sorting process before entering the strapping process. The production speed of existing bag making machines is very fast. If this process is manually operated, the efficiency is low and the cost is high, which cannot match the production speed of the bag making machine.

[0003] The conveying and sorting of packaging bags are also operated by equipment, but the existing conveying and sorting equipment has certain defects:

[0004] 1. The packaging bags coming out of the bag making machine may be output in one or more ways depending on the raw materials. The sizes of the packaging bags also vary in size. The operations required for the corresponding adjustments of the conveying and sorting equipment are very complicated. For example, if baffles are used as interval branching equipment, it is necessary to disassemble and assemble the partitions of the entire line, adjust the spacing and quantity, which is time-consuming and labor-intensive.

[0005] 2. Existing conveying and bag sorting equipment generally adopts plane conveying. During the conveying process, the packaging bags are easily affected by external factors and deflected or even turned over, which affects the subsequent processes, especially for small and thin packaging bags.

[0006] 3. Due to problems with the raw materials themselves or the manufacturing process, there are often defective bags coming out of the bag making machine. Manual removal is inefficient and prone to errors. The existing removal method is to set a jet device above the entrance of the conveying equipment to jet the defective bags before they enter to make them fall. However, this method has many problems: there is a certain error rate, and it may not be able to effectively remove defective bags, especially for some bags with larger sizes and weights; in addition, to ensure the removal effect, there needs to be a certain gap between the bag making machine and the conveying and sorting equipment. Bags of different sizes and weights have different optimal gaps. Therefore, calculations and adjustments need to be made before production, which is troublesome to operate. Even at the optimal gap, it cannot be avoided that defective products enter the conveying and sorting mechanism or qualified products fall from the gap; in addition, the airflow generated by the jet method will affect the front and back bags.

[0007] 4. The feeding and discharging directions of the conveying and bag sorting equipment need to correspond to the front and rear equipment. The feeding and discharging directions of the existing conveying and bag sorting equipment are single and inconvenient to adjust, and even the entire equipment needs to be moved, which is not conducive to automated production. Summary of the invention

[0008] In view of the above requirements, the present invention provides a feeding and conveying mechanism for a bag sorting machine, which can adapt to various conveying line quantity and packaging bag size requirements, and can effectively remove defective products with stable conveying.

[0009] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0010] A feeding and conveying mechanism of a bag sorting machine is used for conveying packaging bags, comprising a bottom plate and wall panels on both sides, the wall panels are supported by a certain number of optical axes, the front end of the wall panel is provided with two upper and lower parallel transmission shafts, one end of the transmission shaft is connected to a synchronous pulley, a driving wheel connected to a motor is fixed on the wall panel, the synchronous pulley and the driving wheel are connected by a synchronous belt, and the synchronous belt is reversely connected to the two synchronous pulleys, at least one conveying line is provided between the two wall panels, the conveying line comprises four conveying slider seats, two conveying slider seats are respectively arranged in front and behind and in parallel up and down, the conveying slider seat comprises a slider and a conveying wheel, at least two mounting holes a are provided on the slider, at least one round belt groove a is provided on the conveying wheel, a slider seat mounting shaft passing through the mounting hole a is provided between the two wall panels, the front and rear two conveying wheels located above and the front and rear two conveying wheels located below are respectively covered with conveying round belts, and the transmission shaft passes through the two conveying wheels at the front end. When working, the motor drives the driving wheel and the synchronous pulley to rotate, among which the synchronous pulley located at the top rotates counterclockwise, and the synchronous pulley located at the bottom rotates clockwise, and the transmission shaft and the conveying wheel on it rotate in the corresponding direction. The packaging bag enters between the two conveying wheels at the front end, is clamped by the upper and lower conveying round belts and conveyed backward, and is output from between the two conveying wheels at the rear end. The number of conveying lines can be increased or decreased according to the number of packaging bag lines entering, and the spacing of the conveying lines can be adjusted according to the size of the packaging bags.

[0011] Preferably, the transmission shaft is a spline shaft, and the two conveying wheels at the front end are provided with corresponding spline holes to ensure stable transmission of power.

[0012] Preferably, the front end of the conveyor line is also provided with two upper and lower conveying swing frames, the conveying swing frame includes two side plates, a mounting hole b is provided in the middle of the side plates, a swing rod is provided at one end between the two side plates, and a swing wheel is provided at the other end, and at least one round belt groove b is provided on the swing wheel. The two side plates are located on both sides of the conveying wheel and are sleeved on the transmission shaft through the mounting hole b. The swing wheel and the adjacent conveying wheel are sleeved with a swinging round belt. Cylinder fixing seats are respectively provided on the two sliders at the front end, and a swing cylinder is provided on the cylinder fixing seat. The movable end of the swing cylinder is connected to the swing rod. The plane where the central axis of the swing rod and the mounting hole b is located has a certain angle with the plane where the central axis of the swing wheel and the mounting hole b is located. The upper and lower conveying swing frames are in opposite directions. The diameter of the mounting hole b of the side plate is slightly larger than the diameter of the transmission shaft, and its movement is not affected by the transmission shaft. During normal operation, the upper and lower swing wheels open at a certain angle and rotate in the same direction as the corresponding conveying wheels. The packaging bag enters between the two swing wheels and enters between the two conveying wheels through the swinging round belt and then is conveyed backward. When the detection mechanism in the front detects a defective packaging bag, the swing cylinder drives the swing rod to move, and the conveying swing frame rotates along the transmission shaft. The upper and lower swing wheels resist each other and close the feed port. The defective packaging bag falls from the bottom, and then the swing cylinder drives the upper and lower swing wheels to open and continue to convey.

[0013] Preferably, a tensioning wheel is provided between the synchronous belt pulley and the driving wheel, and the tensioning wheel is installed in the strip groove of the wall panel. The tightness of the synchronous belt is adjusted by adjusting the tensioning wheel at the strip groove position to ensure effective transmission of power.

[0014] Preferably, a locking block is provided on one side of the slider and is sleeved on the slider seat mounting shaft. The locking block is fixed to the slider and has an adjustment hole, in which an adjustment switch is provided. When the adjustment switch is loosened, the slider can move laterally on the slider seat mounting shaft, and when the adjustment switch is tightened, the locking block is fixed, thereby limiting the position of the slider.

[0015] Preferably, one end of the upper and lower slider seat mounting shafts is connected by a connecting block, on which an adjusting screw rod a is provided, and a corresponding nut is fixed on the wall plate. By adjusting the screw rod a, the slider seat mounting shaft can be moved laterally, thereby adjusting the lateral position of the conveying slider seat thereon.

[0016] Preferably, a support seat is provided below the bottom plate, at least two linear guide rails are provided on the support seat, a plurality of sliders are provided on the linear guide rails, the bottom plate is fixed on the sliders, an adjustment screw rod b is provided on one side of the support seat, and a corresponding nut is fixed on the wall plate. By adjusting the screw rod b, the slider, the bottom plate and the entire mechanism thereon can be moved laterally, thereby adjusting the lateral position of the conveying slider seat.

[0017] Preferably, the side of the support seat is provided with a plurality of anchor steels, which can be used to fix the mechanism and adjust the level of the mechanism.

[0018] Preferably, a horizontal baffle is provided between two wall panels below the conveyor line to prevent the packaging bags from falling.

[0019] Preferably, a counter is fixed on the slider at the rear end of the conveyor line to count the number of output packaging bags, so as to facilitate the subsequent sorting and bundling process.

[0020] Preferably, the number of the upper conveyor belts in the conveyor line is not greater than the number of the lower conveyor belts, and the upper conveyor belts are arranged in a staggered manner with the lower conveyor belts. For example, two conveyor belts are arranged in a staggered manner, and three conveyor belts are arranged in a staggered manner, which can better perform clamping and conveying and avoid deflection or falling.

[0021] The advantages of the present invention are: 1. The conveying line in the mechanism is easy to adjust and can adapt to various numbers of packaging bag output lines and packaging bags of various sizes and specifications, greatly saving time and manpower.

[0022] 2. The round belt clamping and conveying can prevent the packaging bags from being deflected or even turned over by external influences, which is beneficial to the progress of subsequent processes.

[0023] 3. The structure for rejecting defective packaging bags is reliable and effective, which avoids the problem of defective packaging bags entering the conveying line and qualified packaging bags being rejected. The process of rejecting defective packaging bags will not affect the packaging bags before and after.

[0024] 4. The lateral position of the conveyor line in the mechanism has a variety of adjustment methods to meet various operating requirements. The conveying direction can also be adjusted as needed. For example, by adjusting the different height positions of the front and rear slider seat mounting shafts on the wall panel, the conveyor line can convey the packaging bags upward or downward. By adjusting the different positions of the front and rear conveying slider seats on the slider seat mounting shafts, the conveyor line can convey the packaging bags to the left or right.
