Description

Technical Field

[0001] This utility model relates to the field of tobacco filter rod forming technology, specifically, to a non-contact glue supply device. Background Technology

[0002] In recent years, with the increasing variety of filter rods, in order to meet the glue supply requirements of different filter rods, the glue supply system for filter rods has also been continuously upgraded. The glue supply methods mainly based on coating and spraying glue can no longer meet the needs of all filter rods. Especially when it comes to special filter rods, high-permeability paper and high-speed molding, the phenomenon of poor adhesion and inaccurate control of glue amount often occurs.

[0003] When addressing weak adhesion issues using glue application methods such as spraying or applying glue, the solutions include adding multiple glue guns or increasing the glue dispensing volume. Adding multiple glue guns increases costs, while increasing the dispensing volume can result in a glue line that is thicker in the middle and thinner at the edges, leading to glue seepage. To ensure accurate glue dispensing for strip materials, an ideal technical solution has been continuously sought. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a non-contact glue application device. This invention enables uniform glue application to strip materials, ensures glue application quality, and solves the problem of precise glue application to strip materials.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a non-contact glue supply device, comprising a support plate, a linear drive mechanism, a glue gun, a glue roller, a drive reduction motor, a guide mechanism, and a glue supply system.

[0006] The linear drive mechanism is installed on the front of the support plate and is used to drive the glue gun to move in a straight line, so that the glue gun moves closer to or away from the glue application roller.

[0007] The glue gun is fixed on the linear drive mechanism and is used to dispense white glue;

[0008] The glue-applying roller is coaxially mounted at the end of the output shaft of the drive geared motor and located on one side of the front of the support plate. It is used to apply the white glue output from the glue gun onto the strip material.

[0009] The drive geared motor is mounted on the back of the support plate and its output shaft is rotatably connected to the support plate to drive the glue coating roller to rotate.

[0010] The guiding mechanism is installed on the front of the support plate and on the side of the coating roller away from the glue gun. It is used to guide the strip material to move close to the coating roller along a predetermined trajectory.

[0011] The glue supply system is connected to the glue gun via pipes and signal lines to supply white glue to the glue gun.

[0012] Based on the above, the support plate is set vertically in the left-right direction, with the front side of the support plate being its front side and the rear side of the support plate being its back side.

[0013] Based on the above, the linear drive mechanism includes a cylinder base, a slide cylinder, and a connecting plate. The cylinder base is installed on the left side of the front side of the support plate. The slide cylinder is horizontally installed on the cylinder base in the left-right direction. The piston rod of the slide cylinder extends out of the right end of its cylinder body. The connecting plate is installed on the right end of the slide of the slide cylinder by screws. The glue gun is installed on the connecting plate, and the outlet of the glue gun is located at the lower right end of the glue gun body.

[0014] Based on the above, the drive reduction motor is installed on the right side of the rear side of the support plate by screws. The output shaft of the drive reduction motor is horizontally rotatably connected to the support plate in the front-back direction and is located on the right side of the slide cylinder. The glue-applying roller is coaxially installed at the front end of the output shaft of the drive reduction motor and is located on the right side of the glue gun. When the piston rod of the slide cylinder extends, the glue gun is close to the glue-applying roller. When the piston rod of the slide cylinder retracts, the glue gun moves away from the glue-applying roller.

[0015] Based on the above, the outlet of the glue gun is equipped with a glue nozzle, which includes an upper cover plate, a glue line distribution plate, and a lower cover plate. The upper cover plate, glue line distribution plate, and lower cover plate are stacked together from top to bottom to cover the outlet of the glue gun and are fixedly connected to the lower right end of the glue gun body with screws. The upper cover plate has a glue outlet hole corresponding to the outlet of the glue gun. The glue line distribution plate has several glue line grooves with front and back spacing and open on the right side corresponding to the glue outlet hole. Each glue line groove diverts the white glue to form several glue lines.

[0016] Based on the above, each of the four corners of the cylinder base is provided with a first adjustment hole in the left-right direction, and a first fastening bolt is installed in each of the first adjustment holes. The cylinder base is fixed to the left side of the front side of the support plate by each of the first fastening bolts.

[0017] Based on the above, two second adjustment holes are opened vertically along the connecting plate, spaced apart from left to right. A slider is slidably installed in each of the two second adjustment holes. The gun body of the glue gun is connected to the two sliders by two second fastening bolts that are respectively threaded onto the two sliders. The two second fastening bolts press and fix the gun body of the glue gun on the connecting plate.

[0018] Based on the above, the guiding mechanism includes two sets of guiding components, which have the same structure and are symmetrically arranged about the glue coating roller.

[0019] The upper guide assembly includes a guide base, an adjusting plate, a fixed shaft, and a guide roller. The guide base is installed on the right side of the front side of the support plate by screws and is located on the upper right side of the output shaft of the drive reduction motor. The adjusting plate is a long strip plate arranged in the left-right direction and parallel to the support plate. A third adjustment hole is opened on the adjusting plate along its length direction. The adjusting plate is pressed and fixed on the front side of the guide base by a third fastening bolt that is slidably installed through the third adjustment hole. The fixed shaft is horizontally fixed on the left side of the front side of the adjusting plate in the front-back direction and is located on the upper right side of the glue coating roller. The guide roller is fitted on the fixed shaft and is rotatably connected to the fixed shaft by bearings. The guide roller is located on the upper right side of the glue coating roller.

[0020] The strip material is inclined downwards from the upper right, wraps around the upper left part of the upper guide roller, then vertically downwards and close to the right side of the coating roller, then wraps around the lower left part of the lower guide roller and is inclined downwards to the right.

[0021] Based on the above, the speed of the drive geared motor is 500rpm-10000rpm; the diameter of the glue-applying roller is 5mm-15mm; when the glue gun is close to the glue-applying roller, the gap between the glue nozzle and the glue-applying roller is 0.02mm-0.2mm.

[0022] This utility model has substantial features and advancements compared to the prior art. Specifically, the non-contact glue dispensing device provided by this utility model has the following advantages:

[0023] On the one hand, by rotating the coating roller, the white latex output from the glue gun is applied to the strip material, making the glue line thickness uniform and the surface smoother. Compared with traditional glue application, it better prevents glue seepage. The coating roller can also make the glue application amount more precise by adjusting the speed and the gap between it and the glue gun.

[0024] On the other hand, by using the glue line distribution plate in the glue nozzle to create various glue line grooves, multiple glue lines can be sprayed from a single glue gun. Furthermore, by replacing the glue line distribution plate with different glue line groove sizes, quantities, and distribution positions, it is possible to apply glue to strip materials of various glue line specifications, saving costs and precisely controlling the width, quantity, and position of the glue lines.

[0025] In summary, this invention enables uniform gluing of strip materials, ensures gluing quality, and solves the problem of precise gluing supply for strip materials. Attached Figure Description

[0033] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0034] Example 1

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a non-contact glue supply device includes a support plate 1, a linear drive mechanism, a glue gun 2, a glue roller 3, a drive reduction motor 4, a guide mechanism, and a glue supply system.

[0036] A linear drive mechanism is installed on the front of the support plate 1 to drive the glue gun 2 to move in a straight line, so that the glue gun 2 moves closer to or away from the glue roller 3.

[0037] The glue gun 2 is fixed on the linear drive mechanism and is used to output white glue;

[0038] The glue-applying roller 3 is coaxially mounted at the end of the output shaft of the drive reduction motor 4 and located on one side of the front of the support plate 1, and is used to apply the white glue output by the glue gun 2 onto the strip material 19.

[0039] The drive reduction motor 4 is mounted on the back of the support plate 1 and its output shaft is rotatably connected to the support plate 1 to drive the glue coating roller 3 to rotate.

[0040] The guide mechanism is installed on the front of the support plate 1 and on the side of the glue roller 3 away from the glue gun 2, and is used to guide the strip material 19 to move close to the glue roller 3 along a predetermined trajectory.

[0041] The glue supply system is connected to the glue gun 2 via pipes and signal lines to supply white glue to the glue gun 2.

[0042] The support plate 1 is vertically arranged in the left-right direction, with its front side being its front side and its rear side being its back side.

[0043] Specifically, the linear drive mechanism includes a cylinder base 5, a slide cylinder 6, and a connecting plate 7. The cylinder base 5 is installed on the left side of the front side of the support plate 1. The slide cylinder 6 is horizontally installed on the cylinder base 5 in the left-right direction. The piston rod of the slide cylinder 6 extends out of the right end of its cylinder body. The connecting plate 7 is installed on the right end of the slide of the slide cylinder 6 by screws. The glue gun 2 is installed on the connecting plate 7. The outlet of the glue gun 2 is located at the lower right end of the glue gun body.

[0044] Specifically, the drive reduction motor 4 is mounted on the right side of the rear side of the support plate 1 by screws. The output shaft of the drive reduction motor 4 is horizontally rotatably connected to the support plate 1 in the front-rear direction and is located on the right side of the slide cylinder 6. The glue application roller 3 is coaxially mounted at the front end of the output shaft of the drive reduction motor 4 and is located on the right side of the glue gun 2. When the piston rod of the slide cylinder 6 extends, the glue gun 2 is close to the glue application roller 3; when the piston rod of the slide cylinder 6 retracts, the glue gun 2 moves away from the glue application roller 3. The speed of the drive reduction motor 4 is adjustable, with a speed range of 500rpm-10000rpm. This allows for adjustment of the speed of the glue application roller 3, enabling precise adjustment of the glue application amount. Furthermore, different diameter glue application rollers 3 can be selected according to different working conditions, with a diameter range of 5mm-15mm.

[0045] Specifically, the outlet of the glue gun 2 is equipped with a glue nozzle 8, which includes an upper cover plate 9, a glue line distribution plate 10, and a lower cover plate 11. The upper cover plate 9, glue line distribution plate 10, and lower cover plate 11 are stacked together from top to bottom, covering the outlet of the glue gun 2 and fixed to the lower right end of the glue gun body of the glue gun 2 with screws. The upper cover plate 9 has a glue outlet hole (not shown in the figure) corresponding to the outlet of the glue gun 2. The glue line distribution plate 10 has several glue line grooves 12 with front and back spacing and open on the right side, corresponding to the glue outlet hole. Each glue line groove 12 diverts the white glue to form several glue lines. By replacing the glue line distribution plate 10 with different glue line grooves 12 in size, quantity, and distribution position, the glue supply needs of various glue line specifications with different widths, quantities, and positions of the strip material 19 can be met.

[0046] In this embodiment, the guiding mechanism includes two sets of guiding components. The two sets of guiding components have the same structure and are arranged symmetrically about the glue coating roller 3.

[0047] The upper guide assembly includes a guide base 13, an adjusting plate 14, a fixed shaft 15, and a guide roller 16. The guide base 13 is installed on the right side of the front side of the support plate 1 by screws and is located on the upper right side of the output shaft of the drive reduction motor 4. The adjusting plate 14 is a long strip plate arranged in the left-right direction and parallel to the support plate 1. A third adjustment hole 17 is opened on the adjusting plate 14 along its length direction. The adjusting plate 14 is pressed and fixed on the front side of the guide base 13 by a third fastening bolt 18 that is slidably installed through the third adjustment hole 17. The fixed shaft 15 is horizontally fixed on the left side of the front side of the adjusting plate 14 in the front-back direction and is located on the upper right side of the glue coating roller 3. The guide roller 16 is fitted on the fixed shaft 15 and is rotatably connected to the fixed shaft 15 through a bearing (not shown). The guide roller 16 is located on the upper right side of the glue coating roller 3.

[0048] The strip material 19 slopes downwards from the upper right, wraps around the upper left of the upper guide roller 16, and then vertically downwards, passing close to the right side of the coating roller 3. It then wraps around the lower left of the lower guide roller 16 and slopes downwards to the right. The strip material 19 changes its trajectory via the guide roller 16. The position of the guide roller 16 can be adjusted by adjusting the installation position of the adjusting plate 14, thereby adjusting the distance between the strip material 19 and the coating roller 3 to achieve different adhesive lines. The specific adjustment operation for the installation position of the adjusting plate 14 is as follows: loosening the third fastening bolt 18 allows the adjusting plate 14 to rotate and slide relative to the third fastening bolt 18 through the third adjusting hole 17, thus adjusting the position of the guide roller 16 to a suitable position. Then, tightening the third fastening bolt 18 fixes the adjusting plate 14 in place.

[0049] The specific working process of this embodiment is as follows:

[0050] (1) In the initial state, the piston rod of the slide cylinder 6 is in the retracted state, and the glue gun 2 is away from the glue roller 3;

[0051] (2) When it is necessary to apply glue, the piston rod of the slide cylinder 6 extends, and the slide of the slide cylinder 6 drives the glue gun 2 to move to the right through the connecting plate 7, so that the glue gun 2 is close to the glue roller 3 and the glue nozzle 8 is close to the glue roller 3. Then, the drive reduction motor 4 starts and drives the glue roller 3 to rotate counterclockwise. The strip material 19 is guided to move from top to bottom through the two guide rollers 16. At the same time, the glue supply system receives the glue supply signal and starts to provide white glue to the glue gun 2. The glue gun 2 starts to dispense glue. At the outlet of the glue gun 2, glue lines are formed by the glue line distribution plate 10 in the glue nozzle 8. Each glue line is attached to the glue roller 3 and is evenly coated onto the strip material 19 under the rotation of the glue roller 3.

[0052] (3) When the glue supply ends or the glue gun 2 needs to be cleaned, the strip material 19 stops moving, the drive reduction motor 4 stops, the piston rod of the slide cylinder 6 retracts, and the glue gun 2 moves away from the glue coating roller 3.

[0053] Example 2

[0054] like Figure 1 , Figure 2 and Figure 6 As shown, the difference from Embodiment 1 is that the cylinder base 5 has a first adjustment hole 20 horizontally opened at each of the four corners along the left and right directions, and a first fastening bolt 21 is installed in each of the first adjustment holes 20. The cylinder base 5 is fixed to the left side of the front side of the support plate 1 by each of the first fastening bolts 21.

[0055] Furthermore, two second adjustment holes 22 spaced apart are opened vertically along the upper edge of the connecting plate 7. Each of the two second adjustment holes 22 is fitted with a sliding block 23. The gun body of the glue gun 2 is connected to the two sliding blocks 23 by two second fastening bolts 24 that are respectively threaded onto the two sliding blocks 23. The two second fastening bolts 24 press and fix the gun body of the glue gun 2 onto the connecting plate 7.

[0056] When it is necessary to adjust the thickness of the glue line, it can be achieved by adjusting the gap between the glue gun 2 and the glue roller 3 when the glue gun 2 is close to the glue roller 3, so that when the glue gun 2 is close to the glue roller 3, the gap between the glue nozzle 8 and the glue roller 3 is in the range of 0.02mm-0.2mm.

[0057] Specifically, the position of the glue gun 2 is adjusted by adjusting the position of the slider 23 on the cylinder base 5 or the connecting plate 7, thereby adjusting the gap between the glue gun 2 and the glue roller 3 when the glue gun 2 is close to the glue roller 3. Loosening each of the first fastening bolts 21 adjusts the horizontal position of the cylinder base 5, thereby adjusting the horizontal position of the glue gun 2. Loosening each of the second fastening bolts 24 adjusts the vertical position of the slider 23 on the connecting plate 7, thereby adjusting the vertical position of the glue gun 2, thus adjusting the gap between the glue gun 2 and the glue roller 3 when the glue gun 2 is close to the glue roller 3.

[0058] It should be noted that the glue supply system is existing technology in this field. In this embodiment, the glue supply system includes a glue tank, a piston pump, and a controller.

[0059] The glue bucket is used to store white glue, and a liquid level sensor is installed inside the glue bucket to detect the amount of white glue.

[0060] The piston pump is connected to the glue bucket and glue gun 2 via pipelines, and is used to pump white glue from the glue bucket to the glue gun 2. The piston pump is equipped with a filter device and a pressure regulating device.

[0061] The controller is connected to the piston pump, glue gun 2, and level sensor via signal lines to control the piston pump pressure and glue dispensing from glue gun 2. The glue tank, piston pump, controller, level sensor, piping, and signal lines are not shown in the diagram; they are standard designs and commercially available. Their specific construction and operating principles will not be elaborated upon. The controller is a PLC or microcontroller, and its signal control portion utilizes conventional control technology in this field, without involving any new computer programs.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and not to limit it; although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents; without departing from the spirit of the technical solution of the utility model, they should all be included in the scope of the technical solution for which protection is requested in the utility model.
