Description

Technical Field

[0001] The utility model belongs to the technical field of bag pressing and synchronous conveying, in particular to a bag pressing and synchronous conveying mechanism. Background Art

[0002] The bagging machine is responsible for removing bags from the bag storage compartment one by one. If bags are curled during storage, they will also be curled as they are removed. If they are not externally leveled, the bags, due to their light weight, are prone to tilting and shifting. This can also lead to inaccurate bag positioning (since the bagging machine's function is to remove bags one by one and place them in a fixed position for later use, inaccurate positioning can affect subsequent processes).

[0003] Most bag pressing mechanisms on the market use unpowered nylon rollers. After pressing the bag, the rollers are just driven and do not provide power. In addition, the contact surface between the rollers and the belt is point contact, which has poor stability. Utility Model Content

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: a bag pressing and synchronous conveying mechanism, including a base and a support frame, the support frame is fixed to the periphery of the base, and a transmission mechanism arranged around the support frames, the transmission mechanism is used to transport the bags; it also includes a bag pressing mechanism arranged at the upper end of the support frame, the bag pressing mechanism is used to flatten the bags.

[0006] Furthermore, the transmission mechanism includes a power rod, a transmission roller, a passive roller, a driving wheel and a bag pressing synchronous wheel. The power rod is rotatably arranged between the support frames, one end of the power rod passes through the support frame, the transmission roller is arranged on the upper part of the power rod, the passive roller is rotatably arranged between the support frames, the bag pressing synchronous wheel is arranged at one end of the power rod, a rotating motor is fixed to the lower end of the support frame, the driving wheel is rotatably arranged at the lower end of the support frame, the bag pressing synchronous wheel is rotatably arranged between the support frames, a transmission chain is wound between the driving wheel and the bag pressing synchronous wheel, and a belt is wound between the transmission roller and the passive roller.

[0007] Furthermore, the bag pressing mechanism includes a telescopic universal joint, a secondary driving rod, a bracket and a secondary driving roller. The telescopic universal joint is arranged through the upper end of the support frame, the power rod passes through one end of the support frame and is fixed with cylindrical gear 1, the telescopic universal joint passes through one end of the support frame and is fixed with cylindrical gear 2 engaged with cylindrical gear 1, the bracket is arranged at the other end of the telescopic universal joint, and the other end of the telescopic universal joint passes through the bracket, the secondary driving rod is rotatably arranged between the brackets, the secondary driving roller is rotatably arranged between the brackets, a downward pressure synchronous belt is wound between the secondary driving rod and the secondary driving roller, the lower end of the bracket is provided with an auxiliary downward pressure guide plate, the upper end of the bracket is dynamically connected to the movable part of the air pump, and the air pump is arranged at the upper end of the bracket.

[0008] Furthermore, a photoelectric sensor is fixedly connected to the upper end of the side of the base, a microprocessor is fixedly connected to the lower end of the base, and the photoelectric sensor is connected to the microprocessor through a wire.

[0009] Furthermore, the downward pressing synchronous belts are in two groups and are symmetrical along the center line. The downward pressing guide plate is concave, and the upper end of the downward pressing guide plate is connected to the lower end of the bracket.

[0010] Furthermore, the rotating motor is connected to the microprocessor via a wire, and the air pump is connected to the microprocessor via a wire.

[0011] Furthermore, a laser photoelectric emitter compatible with the photoelectric sensor is provided at the upper end of the bracket, and the laser photoelectric emitter emits a light beam of φ1 to 2 m.

[0012] After adopting the above structure, the beneficial effects of the utility model are as follows:

[0013] (1) The meshing transmission between the cylindrical gear 1 and the cylindrical gear 2 between the transmission mechanism and the bag pressing mechanism realizes the synchronous transmission of the transmission and bag pressing operations, prevents the bag from tilting and causing the conveying position deviation, and can flatten the uneven bags to ensure smooth conveying.

[0014] (2) The bag pressing mechanism on the market basically uses a single or multiple pressing wheels. The contact surface between the pressing wheel and the belt is point contact, and the pressing wheel has no power. The improved bag pressing mechanism not only has a large contact surface (surface contact) for the bag pressing, but also has power and is more reliable.
