[0038] Embodiment one

[0039] Referring to Figures 1-5 The application discloses an automatic glue feeding device for corrugated paper production, which comprises a main body assembly 1, wherein the main body assembly 1 comprises: side plates 11, which are symmetrical in the middle and are rotationally connected with conveying rollers 12; glue tanks 13, which are arranged between the side plates 11; glue feeding assemblies 2, which are arranged on the side plates 11 and the glue tanks 13, the glue feeding assemblies 2 comprise: glue grooves 21, which are arranged on the glue tanks 13, and the output shafts of the glue tanks 13 are located above the glue grooves 21; side blocks 221, which are symmetrically and fixedly connected to the right side walls of the left side plates 11; moving blocks 22, which are slidingly connected between the side blocks 221; supporting plates 231, which are fixedly connected to the right side walls of the left side plates 11; springs 23, which are fixedly connected between the moving blocks 22 and the supporting plates 231; connecting rods 24, which are fixedly connected to the right side walls of the moving blocks 22; glue plugs 25, which are fixedly connected to the bottoms of the connecting rods 24 and extend into the glue grooves 21; motors 26, which are arranged on the left side walls of the left side plates 11, and the output shafts of the motors 26 extend through and reach between the side plates 11; cams 27, which are arranged on the output shafts of the motors 26. The bottoms of the supporting plates 231 are fixedly connected with sliding rods 241, the sliding rods 241 extend through the connecting rods 24, and the connecting rods 24 are slidingly connected to the sliding rods 241. The outer side walls of the sliding rods 241 are provided with light-reflecting sheets 3, the left side walls of the right side plates 11 are provided with photoelectric sensors 31, the photoelectric sensors 31 are located on the same horizontal line as the light-reflecting sheets 3, the tops of the right side plates 11 are provided with sound-light alarms 32, and the light-reflecting sheets 3, the photoelectric sensors 31 and the sound-light alarms 32 are electrically connected through a controller.

[0040] In use, workers place corrugated paper to be glued on the conveying rollers 12, and start the motor 26, the motor 26 drives the cam 27 to rotate, when the protruding part of the cam 27 rotates to the upper side, the cam 27 lifts the moving block 22 upward, the spring 23 is compressed, the moving block 22 drives the glue plug 25 to rise through the connecting rod 24, at this time, the glue in the moving block 22 flows to the corrugated paper under the action of gravity, when the cam 27 continues to rotate, the lower point rotates to the upper side, the moving block 22 returns to the bottom under the action of the spring 23, the glue plug 25 moves downward, the glue plug 25 enters the output port of the glue groove 21, the glue groove 21 stops feeding glue, and the cycle is repeated, so that intermittent glue feeding is realized, the corrugated paper crest position is glued separately, and glue waste is avoided.

[0041] When the connecting rod 24 moves, it slides on the sliding rod 241. The sliding rod 241 guides the movement of the connecting rod 24, thereby increasing the stability of the connecting rod 24 when it moves the rubber stopper 25. When the connecting rod 24 moves the rubber stopper 25 to the top, the connecting rod 24 blocks the reflector 3, and the light signal received by the photoelectric sensor 31 weakens accordingly. When the rubber stopper 25 closes the dispensing port, the reflector 3 is exposed, and the light signal received by the photoelectric sensor 31 is stronger. Based on the presence or absence of a light signal or the change in the intensity of the light signal, it is converted into an electrical signal output to determine the open or closed state of the rubber stopper 25. Once an abnormality occurs, the photoelectric sensor 31 sends an electrical signal to the controller (not shown in the figure), and the controller activates the audible and visual alarm 32 to sound an alarm, facilitating timely correction by the staff.

[0042] The aforementioned photoelectric sensor 31 is based on the photoelectric effect, meaning that when light shines on a photoelectric element, the electrical characteristics of the element change. When an object blocks the light path between the light source and the photoelectric element, the intensity of the light received by the photoelectric element changes, thus altering the output electrical signal, thereby detecting the presence of the object. The audible and visual alarm 32 mainly consists of an audible alarm unit, a visual alarm unit, a control circuit, and a power supply. When a trigger signal is received from the sensor or control system, the control circuit drives the audible and visual alarm units to operate. The specific structure will not be described in detail here.

[0043] Example 2

[0044] An auxiliary function has been added based on Embodiment 1.

[0045] See Figures 1-5 The outer wall of the movable block 22 is symmetrically and fixedly connected to a slider 222, which is slidably connected to a groove opened on the opposite surface of the side block 221. Insulation cotton 211 is provided on the outside of the glue groove 21. A connecting block 4 is fixedly connected to the left side wall of the cam 27. Both the connecting block 4 and the output shaft of the motor 26 have threaded holes, and bolts 41 are threaded into the threaded holes.

[0046] When the moving block 22 moves up and down, the sliders 222 on both sides slide in the side blocks 221, the sliders 222 guide the movement of the moving block 22, thereby increasing the stability of the moving block 22 when moving, facilitating accurate control of whether the rubber plug 25 discharges glue or not. The heat preservation cotton 211 outside the glue groove 21 preserves the glue in the glue groove 21, reduces the cooling speed of the glue, thereby facilitating the glue coating operation on the corrugated paper. The staff disassembles the motor 26 by unscrewing the bolt 41, since the corresponding central angle of the convex part of the cam 27 determines the opening time of the rubber plug 25, that is, the glue supply time; and the corresponding central angle of the concave part of the cam 27 is the closing time of the rubber plug 25, that is, the glue supply stopping time. The base circle radius and lift height of the cam 27 and other parameters also affect the movement speed and stroke range of the rubber plug 25, thereby affecting the glue supply flow. The connecting block 4 and the bolt 41 facilitate the staff to replace the motors 26 with different specifications in diameter, thereby flexibly adjusting the glue supply time and flow, adapting to different specifications of corrugated paper production processes.
