Description

Technical Field

[0001] The utility model relates to the technical field of corrugated cardboard production, and particularly relates to a glue amount control mechanism for a glue applicator in corrugated cardboard production. Background Art

[0002] The cardboard used in existing corrugated cartons generally needs to be pasted in multiple layers, which requires gluing and pressing processes for the cardboard. The traditional gluing and pressing processes are mostly carried out separately. After the gluing is completed by the gluing device, the operator needs to manually press the cardboard.

[0003] Chinese Patent Authorization Publication No. CN218610108U discloses a glue applicator for corrugated cardboard production, which relates to the technical field of corrugated paper gluing. It includes a base. Both the front and rear sides of the middle part of the upper surface of the base are fixedly connected with brackets. A glue applicator roller is rotatably connected between the two brackets. The front bracket is equipped with a glue applicator motor, and the output end of the glue applicator motor is fixedly connected with the glue applicator roller. A glue tank is fixedly connected between the two brackets. The bottom of the glue tank is hollowed out. The bottom of the glue tank coincides with the glue applicator roller and is rotatably connected with the glue applicator roller. A communication pipe is fixedly connected to the front end of the glue tank. The top of the communication pipe is fixedly connected with a funnel II. A glue pool is fixedly connected between the two brackets. A conduit is fixedly connected to the front end of the glue pool. The top of the conduit is fixedly connected with a funnel I. A coating roller is rotatably connected between the two brackets. The utility model can continuously supply glue to the coating roller and the glue applicator roller by setting the glue pool, the coating roller, the glue applicator roller and the glue tank. The above existing technical solution has the following deficiencies: This technical solution can press the corrugated cardboard by machine by setting a pressure roller and a pressing motor, liberating the workers and improving the pressing efficiency. However, this technical solution is relatively lacking in controlling the amount of glue dropping. It requires manual control of the glue amount, and the glue outlet is prone to adhesion of dried glue, making it difficult to complete the subsequent gluing work. Therefore, we need to design a glue amount control mechanism for a glue applicator in corrugated cardboard production to solve the above-mentioned problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a glue amount control mechanism for a glue applicator in corrugated cardboard production to solve the problem of difficult glue amount control of the glue applicator in the above background art.

[0005] To achieve the above object, the utility model provides the following technical solution: A glue amount control mechanism for a sizing machine in corrugated cardboard production, including a base, on the top of the base is installed a sizing machine housing, and on the top of the sizing machine housing is installed a support frame. On the top of the support frame is installed a storage tank, and at the bottom of the support frame is installed a feeding pipe, and a control valve is installed on the outer side of the feeding pipe. Inside the support frame is installed a bearing box, and at the bottom of the bearing box are respectively installed a weight sensor and a single-chip microcomputer.

On the top of each first thread sleeve is installed a clamping plate, and on the inner side of the clamping plate are evenly installed anti-slip protrusions. On the top of the base is placed a corrugated cardboard, and on one side inside the base is installed a first motor.

[0006] When using a glue amount control mechanism for a sizing machine in corrugated cardboard production with this technical solution, through the mutual cooperation of the through pipe and the nozzle, the corrugated cardboard after sizing can be dried, improving the work efficiency.

[0012] Preferably, the sizes of the rotating blocks are equal to the sizes of the rotating grooves, and the cross-sections of the rotating blocks are all arranged in a T shape.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: The glue amount control mechanism for the corrugated cardboard production gluing machine not only realizes the function of controllable glue amount, but also realizes the function of integrated drying and purification;

[0014] (1) During use, the glue in the storage tank falls into the inside of the bearing box.

[0015] (2) Through the mutual cooperation of the through pipe and the nozzle, the corrugated cardboard after gluing can be dried, improving the working efficiency. The harmful gases generated during the drying process are absorbed by the activated carbon adsorption net inside the purification box and discharged, thus ensuring the healthy living state of the staff. At the same time, the shape of the slow-flow plate is set in a wave shape, which can prolong the contact time between the harmful gases and the activated carbon adsorption net, making the purification work more efficient. At the same time, by setting the fixing mechanism, the purification box and the internal purification components can be replaced and cleaned regularly, effectively prolonging their service life and use value.
