Description

Technical Field

[0001] The present invention relates to the technical field of diaper production, and more particularly to a rapid glue spraying device for diaper production. Background Art

[0002] The key core technology of diapers is the "core". From a technical perspective, the diaper core has undergone three revolutions so far. Diapers are disposable products made of non-woven fabrics, toilet paper, fluff pulp, polymer absorbent resin, PE film, rubber bands and other materials. There are two types: for infants and for adults.

[0003] The shortcomings of the existing technology: During the diaper production process, it is necessary to spray glue on the surface of the diaper to stick different production raw materials together. However, most of the existing glue spraying equipment can only spray glue on specified sizes. When facing diapers used for different age needs, the diaper raw materials and the glue spraying area will change accordingly. The existing equipment is difficult to meet the production needs of glue spraying raw materials for diapers of different sizes. For this reason, we propose a fast glue spraying device for diaper production. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a rapid glue spraying device for diaper production to solve the problems existing in the above-mentioned background technology.

[0005] The present invention provides the following technical solution: a rapid glue spraying device for diaper production, comprising a machine base, an upper shell being installed at the upper end of the machine base, a lower shell being installed at the lower end of the machine base, a plurality of guide rollers being installed in the upper shell and the lower shell, diaper raw materials being guided and conveyed on the circumferential surfaces of the guide rollers, a glue spraying assembly being installed in the upper shell, the glue spraying assembly comprising a mounting frame, a mounting shell, a dynamic glue spraying head, a fixed glue spraying head and a conveying pipe, a pair of the mounting frames being installed on the inner wall of the upper shell, the mounting shell being installed between the mounting frames, a plurality of the dynamic glue spraying heads being rotatably connected in the mounting shell by a rotating rod, the fixed glue spraying head being fixedly connected in the mounting frame, the conveying pipe being installed at the upper end of the mounting shell, the conveying pipe being connected to the dynamic glue spraying head and the fixed glue spraying head by a diverter hose, a hot melt box being installed at the upper end of the upper shell, the hot melt box and the conveying pipe being connected by a connecting pipe;

[0006] Preferably, a large gear and a small gear are respectively installed on the circumferential surface of a group of the rotating rods, and a plurality of guide frames are installed on the surface of the mounting shell. Racks are slidably connected in the guide frames, and the racks are respectively engaged with the large gear and the small gear.

[0007] Preferably, a connecting rod is installed on the upper end of the rack, a micro cylinder is installed on the surface of the mounting shell, and the output end of the micro cylinder is connected to the connecting rod.

[0008] Preferably, a correction component is installed in the upper shell body, and the correction component includes a connecting frame, a rotating frame and a correction wheel. A pair of the connecting frames are slidably connected to the surface of the machine base, and the rotating frame is installed at the upper end of the connecting frame. Multiple correction wheels are rotatably connected to the rotating frame through a rotating shaft. A mounting shaft is installed on the surface of the machine base, and the circumferential surface of the mounting shaft is rotatably connected to a connecting gear. The surface of the connecting frame is provided with tooth grooves, and the connecting gears are engaged with the tooth grooves.

[0009] Preferably, an electric push rod is installed on the upper end of the machine base, and the output of the electric push rod is connected to a connecting block, and the connecting block is connected to one of the connecting frames.

[0010] Preferably, a detection probe is installed on the upper end of the machine base, and the detection probe is used to transmit a signal so that the controller controls the operation of the electric push rod.

[0011] Preferably, a first negative pressure box is installed in the upper shell, and a second negative pressure box is installed in the lower shell, and air suction ports are provided on the surfaces of the first negative pressure box and the second negative pressure box.

[0012] Technical effects and advantages of the present invention:

[0013] 1. The present invention controls the operation of a micro-cylinder to drive multiple racks to slide simultaneously in a guide frame. Due to the difference in diameter between the large gear and the small gear, the rotating rod in each group is driven to rotate at different angles, which can drive different dynamic glue spraying heads in each group to rotate at different angles. This makes the spacing between the dynamic glue spraying head and the fixed glue spraying head close after adjustment, and can change the range of glue sprayed by the dynamic glue spraying head, thereby achieving the effect of spraying glue on diaper materials of different sizes, realizing the adjustment of the glue spraying area while ensuring the uniformity of the glue spraying.

[0014] 2. The present invention uses the functions of the first negative pressure box and the second negative pressure box. After the diaper raw material spraying is completed, in the subsequent transportation process, the external negative pressure fan is controlled to operate, so that a negative pressure environment is formed in the first negative pressure box and the second negative pressure box. The air around the diaper raw material spraying surface is sucked in through the suction port, which can not only absorb part of the dust to prevent dust from falling on the diaper raw material spraying surface, but also absorb the odor generated on the spraying surface, thereby achieving the effect of odor purification.

DETAILED DESCRIPTION

[0021] The technical solutions of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The rapid glue spraying device for diaper production involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] like Figure 1-4As shown, in one embodiment, a rapid glue spraying device for diaper production is proposed, including a machine base 1, an upper shell 101 is installed on the upper end of the machine base 1, and a lower shell 102 is installed on the lower end of the machine base 1. A plurality of guide rollers 103 are installed in the upper shell 101 and the lower shell 102. Diaper raw materials 104 are guided and transported on the circumferential surfaces of the guide rollers 103. A glue spraying assembly 2 is installed in the upper shell 101. The glue spraying assembly 2 includes a mounting frame 201, a mounting shell 202, a dynamic glue spraying head 203, a fixed glue spraying head 205 and a conveying pipe 206. A pair of mounting frames 201 and 202 are provided. 01 is installed on the inner wall of the upper shell 101, the mounting shell 202 is installed between the mounting brackets 201, multiple dynamic glue spray heads 203 are rotatably connected in the mounting shell 202 through the rotating rod 204, the fixed glue spray head 205 is fixedly connected in the mounting bracket 201, the delivery pipe 206 is installed at the upper end of the mounting shell 202, and the delivery pipe 206 is connected to the dynamic glue spray head 203 and the fixed glue spray head 205 through a diversion hose 207. A hot melt box 208 is installed at the upper end of the upper shell 101, and the hot melt box 208 and the delivery pipe 206 are connected through a connecting pipe 209.

[0023] In actual application of the embodiment of the present invention, the diaper raw material 104 is conveyed through the surface of the guide roller 103 in the upper shell 101 and the lower shell 102, so that the diaper raw material 104 continues to pass under the glue spraying assembly 2. When the glue spraying assembly 2 is running, the material is conveyed through the hot melt box 208, enters the conveying pipe 206 through the connecting pipe 209, and then is conveyed to the multiple dynamic glue spraying heads 203 and the fixed glue spraying heads 205 through the diversion hose 207. Subsequently, the glue sprayed by the multiple dynamic glue spraying heads 203 and the fixed glue spraying heads 205 falls on the diaper raw material 104 below, thus completing the effect of glue spraying on the diaper raw material 104. When facing diaper raw materials 104 of different sizes, the rotating rod 204 is controlled to rotate, and the rotating rod 204 will control the dynamic glue spraying head 203 to rotate. By adjusting the spacing equidistantly, the range of glue sprayed by the dynamic glue spraying head 203 can be changed, thereby achieving the effect of glue spraying on diaper raw materials 104 of different sizes.

[0024] like Figure 3 As shown, in one embodiment, a large gear 3 and a small gear 301 are respectively installed on the circumferential surface of a group of rotating rods 204, and a plurality of guide frames 302 are installed on the surface of the mounting shell 202. The guide frames 302 are all slidably connected to the racks 303, and the racks 303 are respectively engaged with the large gear 3 and the small gear 301.

[0025] When the embodiment of the present invention is actually used, by controlling multiple racks 303 to slide simultaneously in the guide frame 302, the large gear 3 and the small gear 301 can be driven to rotate at the same time. Since there is a difference in diameter between the large gear 3 and the small gear 301, the rack 303 drives the rotating rod 204 in each group to rotate at different angles under the same moving distance, which can drive different dynamic glue spraying heads 203 in each group to rotate at different angles, so that the distance between the glue spraying ports of the dynamic glue spraying head 203 and the fixed glue spraying head 205 is close after adjustment, and the uniformity of glue spraying can be ensured while adjusting the glue spraying area.

[0026] like Figure 3 As shown, in one embodiment, a connecting rod 304 is installed on the upper end of the rack 303 , a micro cylinder 305 is installed on the surface of the mounting shell 202 , and the output end of the micro cylinder 305 is connected to the connecting rod 304 .

[0027] In actual application, the embodiment of the present invention controls the operation of the micro cylinder 305, which drives the connecting rod 304 to rotate, and the connecting rod 304 drives the multiple racks 303 to slide in the guide frame 302, thereby achieving the effect of controlling the angle adjustment of the dynamic glue spray head 203, changing the glue spraying area, and adapting to the glue spraying processing of diaper raw materials 104 of different sizes.

[0028] like Figure 2 and 5 As shown, in one embodiment, a correction component 4 is installed in the upper shell 101, and the correction component 4 includes a connecting frame 401, a rotating frame 402 and a correction wheel 403. A pair of connecting frames 401 are slidably connected to the surface of the machine base 1, and the rotating frame 402 is installed at the upper end of the connecting frame 401. Multiple correction wheels 403 are rotatably connected in the rotating frame 402 through a rotating shaft. A mounting shaft 404 is installed on the surface of the machine base 1, and the circumferential surface of the mounting shaft 404 is rotatably connected to a connecting gear 405. A tooth groove 406 is opened on the surface of the connecting frame 401, and the connecting gears 405 are engaged with the tooth groove 406.

[0029] In actual application of the embodiment of the present invention, through the action of the connecting gear 405 and the tooth groove 406, when one of the connecting frames 401 slides, the other connecting frame 401 moves synchronously in the mutual direction, thereby enabling the rotating frames 402 and the correcting wheels 403 on both sides to move in the mutual direction. When the diaper material 104 deviates during the conveying process, the connecting frame 401 can be controlled to move inward at this time, so that the correcting wheels 403 on both sides contact the diaper material 104, pushing the diaper material 104 back to the center position, thereby achieving the effect of correcting the deviation of the diaper material 104 during the conveying process.

[0030] like Figure 5As shown, in one embodiment, an electric push rod 407 is installed on the upper end of the machine base 1, and the output of the electric push rod 407 is connected to a connecting block 408, which is connected to one of the connecting frames 401.

[0031] In actual application of the embodiment of the present invention, the electric push rod 407 is controlled to operate, and the electric push rod 407 drives the connecting block 408 to move, and the connecting block 408 drives one of the connecting frames 401 to slide, thereby achieving the effect of controlling the operation of the correction component 4.

[0032] like Figure 2 As shown, in one embodiment, a detection probe 409 is installed on the upper end of the machine base 1, and the detection probe 409 is used to transmit a signal so that the controller controls the operation of the electric push rod 407.

[0033] When the embodiment of the present invention is actually used, during the transportation of the diaper raw material 104, the detection probe 409 detects the left and right positions of the diaper raw material 104 in real time. When the diaper raw material 104 is offset in position during the transportation, the detection probe 409 transmits a signal to the controller, and the controller controls the electric push rod 407 to start, thereby achieving the effect of controlling the operation of the correction component 4.

[0034] like Figure 3 As shown, in one embodiment, a first negative pressure box 5 is installed in the upper shell 101, and a second negative pressure box 501 is installed in the lower shell 102. The surfaces of the first negative pressure box 5 and the second negative pressure box 501 are both provided with air suction ports 502.

[0035] In actual application of the embodiment of the present invention, after the diaper raw material 104 is sprayed with glue, in the subsequent transportation process, the external negative pressure fan is controlled to operate, so that a negative pressure environment is formed in the first negative pressure box 5 and the second negative pressure box 501, and the air around the sprayed surface of the diaper raw material 104 is sucked through the suction port 502, which can not only absorb part of the dust to prevent dust from falling on the sprayed surface of the diaper raw material 104, but also absorb the odor generated on the sprayed surface, thereby achieving the effect of odor purification.
