Description

Technical Field

[0001] The utility model relates to the technical field of packaging industry, in particular to chain feeding equipment for a foot pier machine. Background Art

[0002] The packaging industry involves the packaging of various items (such as products, parts, and raw materials) using specialized packaging materials and tools, following specific techniques and processes. This process aims to ensure the integrity, safety, and convenience of the items during storage, transportation, and use. The packaging industry plays a vital role in protecting goods, improving logistics efficiency, disseminating information, promoting sales, and promoting environmental protection and sustainable development. With the continuous advancement of technology and the expansion of its application areas, the packaging industry will continue to contribute significantly to the development of various industries.

[0003] Among them, in the contemporary packaging industry, some pallet pads are made by reprocessing old building templates. The foot pad machine for processing the template is to assemble the multi-layer slats manually, clamp them with two sets of cylinders in opposite directions, and send them to the cutting machine mouth. After sending one section, it returns and clamps again to push, and completes the pushing action reciprocatingly.

[0004] However, when the existing technology is actually used, when the foot pier machine is clamping and conveying the slats, sometimes the clamped board head will be misaligned with the unclamped board head just behind the board joint. Under the reaction force of the cutting knife, the rear board head will be inserted into the front panel slat, resulting in an extra layer. In this way, the machine mouth cannot pass through and is stuck. If the length of the foot pier machine clamping plate is increased, the transportation distance of the slats will be reduced, thereby increasing the number of round trips and the transportation distance, increasing the chance of the machine being stuck, and thus affecting the processing efficiency of the pallet pads. Utility Model Content

Under the reaction force of the cutting knife, the rear board head will be inserted into the front panel slat, resulting in an extra layer. In this way, the machine mouth cannot pass through and is stuck. If the length of the foot pier machine splint is increased, the transportation distance of the slats will be reduced, thereby increasing the number of round trips and increasing the transportation distance, increasing the chance of the machine being stuck, and thus affecting the processing efficiency of the pallet pads.

Sliders 13 are fixedly installed at the upper and lower ends of the U-shaped movable platform 12, and the slides 13 are symmetrically distributed at the upper and lower ends of the U-shaped movable platform 12. The upper and lower inner walls of the front ends of the fixed support frame 6 and the movable support frame 7 are provided with limited straight sliding grooves 14, and the slides 13 are movably connected to the inner walls of the limited straight sliding grooves 14, so that the U can be adjusted by the slides 13 in conjunction with the limited straight sliding grooves 14. The U-shaped movable platform 12 is limited in linear movement, and the inner wall of the U-shaped movable platform 12 is connected to the tensioner 15 through the rotating shaft, and the tensioner 15 is meshed and connected to the inner side of the front end of the conveying chain 10, so that the conveying chain 10 is rotated and conveyed by the active sprocket 9 and the tensioner 15. The fixed support frame 6 and the movable support frame 7 are fixedly installed with support plates 16 on the outer side of the middle, and the number of support plates 16 is several, and they are symmetrically distributed on the outer side of the middle of the fixed support frame 6 and the movable support frame 7. A limited telescopic rod 17 is fixedly installed on the inner side of the support plate 16, and the inner telescopic part of the limited telescopic rod 17 is A U-shaped mounting platform 18 is fixedly installed, a support spring 19 is fixedly installed on the inner side of the support plate 16, and the support spring 19 is fixedly installed on the outer side of the U-shaped mounting platform 18 at one end away from the support plate 16. The support spring 19 is in a compressed state, so that the support spring 19 cooperates with the limiting telescopic rod 17 to elastically support the U-shaped mounting platform 18 in a limited position. The inner wall of the U-shaped mounting platform 18 is rotatably connected to a pressure sprocket 20 through a pin shaft, and the pressure sprocket 20 is meshed and connected to the inner side of the middle part of the conveying chain 10, so that the pressure sprocket 20 provides pressure support to the inner side of the middle part of the conveying chain 10;

[0027] A main support frame 21 is fixedly installed on the outer middle part of the movable support frame 7, and a sub-support frame 22 is fixedly installed on the outer middle part of the upper end of the support platform 1.

[0028] Working principle: When in use, the utility model places the slat to be conveyed on the upper front end of the conveying trough 2. When the slat is placed on the upper front end of the conveying trough 2, the pressure sprocket 20 supports the pressure on the inner side of the middle of the conveying chain 10, so that the inner side of the conveying chain 10 will fit against the outer side of the front end of the slat. When the inner side of the conveying chain 10 fits against the outer side of the front end of the slat, the driving motor 8 is turned on by control. When the driving motor 8 is turned on, the active sprocket 9 is driven to rotate. When the active sprocket 9 rotates, it cooperates with the tensioner 15 to drive the conveying chain 10 to rotate and convey. When the conveying chain 10 is rotated and conveyed, the friction force generated by the fit between the inner side of the conveying chain 10 and the outer side of the front end of the slat drives the slat to be continuously conveyed backward, thereby facilitating the continuous backward conveying of the slat.

[0029] At the same time, the fastening nut that locks and tightens the first adjusting screw rod 11 is loosened by rotation. When the fastening nut that locks and tightens the first adjusting screw rod 11 is loosened, the first adjusting screw rod 11 is rotated by turning the handle 25. When the first adjusting screw rod 11 rotates, it will move back and forth due to the force generated by the threaded connection. When the first adjusting screw rod 11 moves back and forth, it will drive the U-shaped movable platform 12 to move linearly back and forth. When the U-shaped movable platform 12 moves linearly back and forth, it will drive the front and rear ends of the tensioning wheel 15 to move linearly. When the tensioning wheel 15 moves linearly back and forth, the tensioning degree of the conveying chain 10 can be adjusted, so that the conveying chain 10 is convenient for clamping the slats to be conveyed, and at the same time, the second adjusting screw rod 23 is locked by rotating and loosening. When the fastening nut for locking and fastening the second adjusting screw rod 23 is loosened, the second adjusting screw rod 23 is rotated by the turntable 24. When the second adjusting screw rod 23 rotates, it will move left and right due to the force generated by the threaded connection. When the second adjusting screw rod 23 moves left and right, it will drive the main support frame 21 to move left and right. When the main support frame 21 moves left and right, it will drive the movable support frame 7 to move left and right in a straight line. When the movable support frame 7 moves left and right in a straight line, it will synchronously drive the conveying chain 10 to adjust the left and right linear movement, so that the distance between the inner sides of the conveying chain 10 for clamping and conveying the slats becomes larger or smaller, thereby realizing the continuous backward conveying of the slats while facilitating the clamping and conveying of slats of different thicknesses.
