Description

Technical Field

[0001] This utility model relates to the field of paper bag production technology, and in particular to a paper bag handle strap attaching device. Background Technology

[0002] Paper bags are becoming increasingly widely used. For paper bag handles, since they lack handles, they are typically glued directly to the outside of the bag, reducing paper and manufacturing costs. This has led to the widespread adoption of external paper bag handle attachment. Existing paper bag handle attachment equipment uses a continuously rotating transmission mechanism to move the handles, but lacks a handle detection mechanism. If no handle enters the machine, it will idle, wasting electricity and causing bags without handles to move to the next process, compromising product quality. Therefore, we propose a paper bag handle attachment device to solve these problems. Utility Model Content

[0003] The purpose of this utility model is to provide a paper bag handle attaching device, which aims to solve the problem of the lack of a handle transmission and detection mechanism, which causes the device to run idle when no handle enters.

[0004] To solve the above-mentioned technical problems, this utility model provides a paper bag handle strap attaching device, including a frame, a strap guiding mechanism on one side of the inner side of the frame, a strap threading mechanism in the middle of the inner side of the frame, and a attaching mechanism at the bottom of the inner side of the frame; the strap guiding mechanism includes an L-shaped plate fixed to the top of the inner side of the frame, a fixed seat fixedly connected to one end of the L-shaped plate, a guide rod slidably connected to the inner bottom wall of the fixed seat, the guide rod passing through the fixed seat, a connecting rod fixedly connected to the top of the outer surface of the guide rod, a guide wheel rotatably connected to one end of the connecting rod, a spring sleeved in the middle of the outer surface of the connecting rod, an adjusting nut threadedly connected to the bottom of the outer surface of the connecting rod, a rubber contact fixedly connected to one end of the connecting rod, a sensor plate fixedly connected to the middle of the inner top wall of the fixed seat, and an audible and visual alarm fixedly connected to the upper surface of the fixed seat.

[0005] Preferably, the rope threading mechanism includes a motor fixed in the middle of the bottom wall of the frame, and the output end of the motor is fixedly connected to a bidirectional screw.

[0006] Preferably, both sides of the outer surface of the bidirectional screw are threaded with a sliding plate, and both sides of the inner side of the sliding plate are slidably connected with a guide rod, which is fixedly connected to the frame.

[0007] Preferably, a slide rail is fixedly connected to the upper surface of the slide plate, a slider is slidably connected to the outer surface of the slide rail, scale lines are provided on the upper surface of the slide rail, and a tensioning bolt is threadedly connected to one side of the upper surface of the slider.

[0008] Preferably, a fixing rod is fixedly connected to the other side of the upper surface of the slider, and a rope threading wheel is rotatably connected to one end of the fixing rod.

[0009] Preferably, the bonding mechanism includes a first conveying roller rotatably connected to the bottom of the inner side of the frame, and an adhesive applicator is fixedly connected to the inner side of the frame near the first conveying roller.

[0010] Preferably, a second conveying roller is rotatably connected to the other side of the inner side of the frame, and a pressure roller is rotatably connected to the side of the inner side of the frame near the second conveying roller. The pressure roller is made of Teflon anti-stick roller.

[0011] Preferably, a cover is fixedly connected to the inner side of the frame near the pressure roller, a fan is fixedly connected to the top of the inner side of the cover, and an electric heating wire mesh is fixedly connected to the bottom of the inner side of the cover.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model relates to a paper bag handle attaching device. The handle is passed through the surface of a guide wheel. Under the angle of the handle and gravity, the guide wheel causes the guide rod to slide downward, compressing the spring and continuously feeding the handle into the device for attachment. When the handle is completely fed, the angle and weight change cause the guide rod to move upward under the action of the spring. The rubber contact point contacts the sensor plate, thereby triggering an audible and visual alarm to remind the staff that the handle may be broken or that the feeding is complete, allowing for timely handling and preventing the machine from running idle and wasting power resources. It also prevents paper bags without attached handles from flowing out, ensuring product quality and increasing the practicality of the equipment.

[0014] 2. This utility model relates to a paper bag handle attaching device. Two sets of sliding plates move closer together or separate under the action of a bidirectional screw, changing the distance between the two sets of opposite rope-threading wheels and altering the position of the slider on the outer surface of the slide rail. This allows for adjustment of the distance between adjacent rope-threading wheels to accommodate paper bag handles of different widths, thus expanding the range of applications. Multiple second conveying rollers are positioned opposite the pressure rollers, pressing the handles and paper bags together during the paper bag conveying process, thereby increasing the load-bearing capacity of the handles. The opening of the cover gradually widens from top to bottom, allowing the drying area to be expanded when the fan and electric heating wire mesh are activated, accelerating the drying of the paper bags and handle glue and saving time.

[0025] This utility model provides a paper bag handle attaching device. Please refer to [link / reference]. Figures 1-6 The system includes a frame 1, a rope guiding mechanism 2 on one side of the inner side of the frame 1, a rope threading mechanism 3 in the middle of the inner side of the frame 1, and a fitting mechanism 4 at the bottom of the inner side of the frame 1. The rope guiding mechanism 2 includes an L-shaped plate 201 fixed to the top of the inner side of the frame 1. A fixed seat 202 is fixedly connected to one end of the L-shaped plate 201. A guide rod 203 is slidably connected to the inner bottom wall of the fixed seat 202. The guide rod 203 passes through the fixed seat 202. A connecting rod 204 is fixedly connected to the top of the outer surface of the guide rod 203. A guide wheel 205 is rotatably connected to one end of the connecting rod 204. A spring 206 is sleeved in the middle of the outer surface of the connecting rod 204. An adjusting nut 207 is threadedly connected to the bottom of the outer surface of the connecting rod 204. A rubber contact 208 is fixedly connected to one end of the connecting rod 204. A sensor plate 209 is fixedly connected to the middle of the inner top wall of the fixed seat 202. An audible and visual alarm 210 is fixedly connected to the upper surface of the fixed seat 202. The rope threading mechanism 3 includes a motor 301 fixed in the middle of the bottom wall of the frame 1, and a bidirectional screw 302 is fixedly connected to the output end of the motor 301.

[0026] Both sides of the outer surface of the bidirectional screw 302 are threadedly connected to the slide plate 303, and both sides of the inner side of the slide plate 303 are slidably connected to the guide rod 304. The guide rod 304 is fixedly connected to the frame 1.

[0027] The upper surface of the slide plate 303 is fixedly connected to the slide rail 305, the outer surface of the slide rail 305 is slidably connected to the slider 306, the upper surface of the slide rail 305 is provided with scale lines 307, and a tensioning bolt 308 is threadedly connected to one side of the upper surface of the slider 306.

[0028] A fixing rod 309 is fixedly connected to the other side of the upper surface of the slider 306, and a rope threading wheel 310 is rotatably connected to one end of the fixing rod 309.

[0029] The bonding mechanism 4 includes a first conveying roller 401 rotatably connected to the bottom of the inner side of the frame 1, and an adhesive applicator 402 is fixedly connected to the inner side of the frame 1 near the first conveying roller 401.

[0030] A second conveying roller 403 is rotatably connected to the other side of the inner side of the frame 1. A pressure roller 404 is rotatably connected to the side of the inner side of the frame 1 near the second conveying roller 403. The pressure roller 404 is made of Teflon anti-stick roller.

[0031] A cover 405 is fixedly connected to the inner side of the frame 1 near the pressure roller 404. A fan 406 is fixedly connected to the top of the inner side of the cover 405, and an electric heating wire mesh 407 is fixedly connected to the bottom of the inner side of the cover 405.

[0032] It should be noted that the rope guiding mechanism 2 guides the carrying rope from the outside to the equipment, and then the rope threading mechanism 3 and the bonding mechanism 4 bond the carrying rope to the paper bag. The L-shaped plate 201 supports the fixed seat 202, which enhances the stability of the support. The guide rod 203 supports the guide wheel 205 through the connecting rod 204, and the spring 206 supports the guide rod 203. When the rope is guided, the carrying rope is passed through the surface of the guide wheel 205. Under the action of the angle of the rope and gravity, the guide wheel 205 causes the guide rod 203 to slide downward, and the spring 206 is compressed, continuously feeding the carrying rope into the equipment for bonding. The guide rod 203 can be adjusted by using the adjusting nut 207 to adjust the stroke according to the material weight and guide angle of the carrying rope, thus enhancing its adaptability. When the carrying rope is finished being conveyed, the change in angle and weight causes the guide rod 203 to move upward under the action of the spring 206. The rubber contact 208 contacts the sensing plate 209, thereby triggering the audible and visual alarm 210, reminding the staff that the carrying rope may have broken or that the conveying has been completed, so that they can deal with it in time, prevent the machine from running idle and wasting power resources, avoid the leakage of paper bags that are not properly attached to the carrying rope, ensure product quality, and increase the practicality of the equipment.

[0033] Preferably, the motor 301 drives the bidirectional screw 302 to rotate, providing power support for the movement and adjustment of the slide plate 303.

[0034] Preferably, the two sets of sliding plates 303 move closer to each other or separate under the action of the bidirectional screw 302, which can change the distance between the two sets of rope-threading wheels 310. The lifting length of the hand rope can be adjusted according to the size of the paper bag, thus enhancing its applicability. The guide rod 304 provides guidance and support for the sliding plates 303.

[0035] Preferably, by changing the position of the slider 306 on the outer surface of the slide rail 305, the distance between two adjacent rope-threading wheels 310 can be adjusted to accommodate paper bag handles of different widths, thus expanding the range of applications. The scale line 307 facilitates precise adjustment of the position of the slider 306, and the tensioning bolt 308 can lock and release the slider 306. When locked, the slider 306 is secure, preventing the rope-threading wheels 310 from moving.

[0036] Preferably, the fixing rod 309 supports the rope threading wheel 310, and the lifting rope can be threaded through the two sets of rope threading wheels 310 facing each other.

[0037] Preferably, the first conveying roller 401 supports and conveys the paper for paper bag processing that enters the inner side of the frame 1. During the conveying process, the glue coater 402 sprays glue evenly onto the paper to facilitate the subsequent bonding of the handle rope.

[0038] Preferably, multiple second conveying rollers 403 are positioned vertically opposite to the pressure roller 404, pressing the handle and paper bag together during the paper bag conveying process, thereby increasing the load-bearing capacity of the handle. The pressure roller 404 is made of Teflon anti-stick roller, which gives it excellent anti-stick properties. Therefore, when it presses the handle and paper bag together, it can prevent the adhesive on the paper bag from adhering to the pressure roller 404, thus improving production efficiency.

[0039] Preferably, the opening of the cover 405 gradually widens from top to bottom, so that when the fan 406 and the electric heating wire mesh 407 are started, the drying range can be expanded, the paper bags and handle rope glue can be dried quickly, and time can be saved.

[0040] In summary, the motor 301 drives the bidirectional screw 302 to rotate, causing the two sets of sliding plates 303 to move closer together or separate, changing the position of the slider 306 on the outer surface of the slide rail 305, and adjusting the distance between the two adjacent rope-threading rollers 310 to accommodate paper bag handles of different widths. The handle is passed through the surface of the guide wheel 205. Under the angle of the rope and gravity, the guide wheel 205 causes the guide rod 203 to slide downwards, compressing the spring 206 and continuously feeding the handle into the equipment for bonding. The fixing rod 309 supports the rope-threading rollers 310. The two sets of opposing rope-threading rollers 310 connect the handles. The first conveying roller 401 feeds the handles into the inner side of the frame 1. The paper used for paper bag processing is supported and conveyed. During the conveying process, glue is evenly sprayed onto the paper by the glue coater 402. Multiple second conveying rollers 403 and pressure rollers 404 are positioned vertically opposite each other, pressing the handle rope and paper bag together during the paper bag conveying process. When the cover 405 is activated, the fan 406 and the electric heating wire mesh 407 can expand the drying range and accelerate the drying of the glue on the paper bag and handle rope. When the handle rope is completely conveyed, the angle and weight change cause the guide rod 203 to move upward under the action of the spring 206. The rubber contact 208 contacts the sensing plate 209, thereby triggering the audible and visual alarm 210 to remind the staff that the handle rope may be broken or the conveying is completed, so that they can deal with it in time.

[0041] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
