Description

Technical Field

[0001] This utility model relates to the field of nonwoven packaging bag production technology, and in particular to a gluing device for producing nonwoven packaging bags. Background Technology

[0002] In the production of nonwoven packaging bags, gluing is a key process to ensure the firmness of the seams (such as the sides and bottom) and handles of the bag. Special gluing equipment is needed to accurately apply the glue to the designated positions, which directly affects the structural strength and finished product quality of the packaging bag. It is one of the core links to achieve large-scale production of nonwoven packaging bags.

[0003] However, existing adhesive coating equipment for nonwoven packaging bag production has significant limitations: most equipment is only equipped with a single-diameter adhesive nozzle, capable of outputting a fixed amount and type of adhesive. In actual production, the adhesive requirements for nonwoven packaging bags of different specifications and uses vary significantly. For example, thin food-grade nonwoven packaging bags require small-diameter adhesive nozzles to avoid glue overflow and contamination of the bag surface, while thick shopping bag seams require large-diameter nozzles to ensure bonding strength, and lightweight vest bag handle bonding requires medium-diameter nozzles to balance adhesive amount and cost. Existing equipment, due to its single-diameter nozzle, cannot adapt to these diverse adhesive coating needs. Therefore, there is an urgent need to develop an adhesive coating equipment for nonwoven packaging bag production that is convenient to apply and can quickly switch between different nozzle diameters to meet various usage requirements, overcoming the shortcomings of current practical applications and satisfying current needs. Utility Model Content

[0004] The purpose of this invention is to provide a coating equipment for the production of nonwoven packaging bags, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A glue-coating device for producing non-woven packaging bags includes a frame, a connecting plate, a transverse mechanism, an adjustable glue-coating mechanism, and a glue delivery mechanism.

The adjustable glue-coating mechanism includes a distribution pipe, glue nozzles, solenoid valves, a small flexible tube, a turntable, and a second motor. The distribution pipe is fixed to the lower side of the connecting plate. There are three glue nozzles, each with a different diameter, and adjacent glue nozzles are at a 70° angle to each other. Each glue nozzle is equipped with a solenoid valve and is connected to the distribution pipe via a small flexible tube. The second motor is fixed to the lower side of the connecting plate, and the turntable is fixed to the output shaft of the second motor. The glue delivery mechanism is installed on the frame and connected to the distribution pipe.

[0006] Preferably, the transverse mechanism includes a first motor, a lead screw, a nut, a slider, and a guide rail. The first motor is fixed to the frame, the lead screw is rotatably connected to the frame, the output shaft of the first motor is connected to the lead screw via a coupling, a nut is installed on the lead screw, the nut is fixed to a connecting plate, two sliders are fixed on the connecting plate, each slider is slidably mounted on a guide rail, and the guide rail is fixed to the frame.

[0007] Preferably, the glue delivery mechanism includes a delivery pump, a glue storage tank, and a large flexible hose. The delivery pump and the glue storage tank are both mounted on the frame. The inlet end of the delivery pump is connected to the glue storage tank through a pipe, and the outlet end of the delivery pump is connected to a distribution pipe through the large flexible hose.

[0008] Preferably, the top of the glue storage tank is provided with a feeding port, and the top of the feeding port is detachably connected to an end cap by a thread, and a sealing ring is installed inside the end cap.

[0009] Preferably, a PLC controller is installed on the frame, and the first motor, the second motor, and the delivery pump are all electrically connected to the PLC controller.

[0010] The beneficial effects of this utility model are as follows: In use, the glue-coating equipment for non-woven packaging bag production first selects a suitable glue-coating nozzle diameter according to actual usage requirements. A second motor drives a turntable to rotate, which in turn rotates and switches the three glue-coating nozzles. The desired nozzle diameter is rotated to a vertical position, and its solenoid valve is opened, while the solenoid valves on the other two nozzles are closed. Then, the non-woven packaging bag is placed under the selected nozzle to await glue application. A delivery pump draws glue from the storage tank and delivers it to a distribution pipe, which then delivers the glue to the nozzle and applies it to the non-woven packaging bag. Simultaneously, a first motor drives a lead screw to rotate, which in turn moves a nut, which in turn moves a connecting plate. The connecting plate then moves the adjustable glue-coating mechanism laterally, thus widening the glue-coating range of the nozzle. In summary, this utility model offers convenient glue application and allows for quick switching between different nozzle diameters, easily meeting various usage needs. Attached Figure Description

When applying glue, first select the appropriate diameter glue-applying nozzle 402 according to the actual usage requirements. The second motor 406 drives the turntable 405 to rotate. The rotation of the turntable 405 drives the three glue-applying nozzles 402 to rotate and switch, so that the glue-applying nozzle 402 of the required diameter is rotated to a vertical position and the solenoid valve 403 on the glue-applying nozzle 402 is opened. The solenoid valves 403 on the other two glue-applying nozzles 402 are closed. Then, the non-woven packaging bag is placed under the selected glue-applying nozzle 402 to wait for glue application.

[0019] The transverse mechanism 3 includes a first motor 301, a lead screw 302, a nut 303, a slider 304, and a guide rail 305. The first motor 301 is fixed to the frame 1, and the lead screw 302 is rotatably connected to the frame 1. The output shaft of the first motor 301 is connected to the lead screw 302 via a coupling. A nut 303 is installed on the lead screw 302 and is fixed to a connecting plate 2. Two sliders 304 are fixed on the connecting plate 2, and each slider 304 is slidably mounted on a guide rail 305. The guide rail 305 is fixed to the frame 1. In use, the first motor 301 drives the lead screw 302 to rotate, which in turn drives the nut 303 to move, which in turn drives the connecting plate 2 to move. The connecting plate 2 then drives the adjustable glue applicator 4 to move transversely, thereby widening the glue applicator range of the glue applicator nozzle 402.

[0020] The glue delivery mechanism 5 includes a delivery pump 501, a glue storage tank 502, and a large flexible hose 503. The delivery pump 501 and the glue storage tank 502 are both mounted on the frame 1.

[0022] Working Principle: This non-woven packaging bag coating equipment first selects the appropriate diameter coating nozzle 402 according to actual usage requirements. The second motor 406 drives the turntable 405 to rotate, which in turn rotates the three coating nozzles 402, switching them between the desired diameter nozzles. The desired nozzle 402 is rotated to a vertical position, and its solenoid valve 403 is opened. The solenoid valves 403 on the other two nozzles are closed. Then, the non-woven packaging bag is placed on the selected nozzle. Below the glue applicator 402, glue is applied. Then, the glue in the glue storage tank 502 is drawn by the delivery pump 501 and delivered to the diversion pipe 401. The diversion pipe 401 delivers the glue to the glue applicator 402 and then applies it to the non-woven packaging bag. At the same time, the first motor 301 drives the lead screw 302 to rotate. The rotation of the lead screw 302 drives the nut 303 to move. The nut 303 drives the connecting plate 2 to move. The connecting plate 2 drives the adjustable glue applicator 4 to move laterally, thereby making the glue applicator 402 have a wider application range.
