[0031] The glue coating machine which is convenient to use comprises a liquid storage device 11, a control device 12 and a perfusion pipe 13. The liquid storage device 11 is connected with the control device 12. The control device 12 is used to control the output amount of glue liquid. The perfusion pipe 13 is passed through the control device 12. The liquid storage device 11 comprises a liquid storage cavity 14 and a conveying structure 15. The conveying structure 15 is placed in the liquid storage cavity 14. The control device 12 is passed through the upper part of the perfusion pipe 13, and a perfusion opening is formed upward. The lower end of the perfusion pipe 13 extends downward to the liquid storage cavity 14. The glue liquid enters the liquid storage cavity 14 along the perfusion pipe 13 through the perfusion opening. The control device 12 drives the conveying structure 15 to convey the glue liquid in the liquid storage cavity 14 to the outside.

[0032] By connecting the liquid storage device 11 and the control device 12 together, and the upper part of the perfusion pipe 13 is passed through the control device 12, wherein the upper part of the perfusion pipe 13 is formed with a perfusion opening facing upward, and the lower part of the perfusion pipe 13 extends into the liquid storage chamber 14, the glue can flow in from the perfusion opening, so that the glue can enter the liquid storage chamber 14, and the glue in the liquid storage chamber 14 is driven by the control device 12 and the conveying structure 15 arranged in the liquid storage chamber 14 to move to the outside, which is very convenient.

[0033] The conveying structure 15 with a simple structure is used to convey the glue liquid in the liquid storage chamber 14, and includes a suction piece 16, a glue pump 17 and an output piece 18. The suction piece 16 is located in the liquid storage chamber 14, and the glue pump 17 is connected to the suction piece 16. The suction piece 16 is used to suck the glue liquid; the interior of the suction piece 16 is hollow to form a suction chamber 21, and the outer surface of the suction piece 16 has a suction port 19 and a glue delivery port 20. The suction port 19 and the glue delivery port 20 are internally connected to the suction chamber 21, and the glue delivery port 20 is connected to the output piece 18 through a pipeline; the glue pump 17 drives the suction piece 16 to suck the glue liquid into the suction chamber 21 through the suction port 19, and drives the glue liquid to flow from the suction chamber 21 through the glue delivery port 20 to the output piece 18, and the output piece 18 transports the glue liquid to the outside.

[0034] By connecting the glue pump 17 to the suction member 16, the suction member 16 is driven to suck the glue into the suction chamber 21 inside the suction member 16, and then the glue pump 17 continues to drive the glue in the suction chamber 21 to be output from the glue delivery port 20 of the suction member 16 to the output member 18, and the structure is simple.

[0035] Among them, a transversely arranged horizontal groove 27 is formed at the lower part of the suction piece 16, and the suction port 19 is formed on the bottom of the horizontal groove 27 and is connected to the suction chamber 21; the horizontal groove 27 is extended along the width direction of the suction piece 16, and the lower part of the suction piece 16 is connected to the bottom of the liquid storage chamber 14, and the glue enters from the groove of the horizontal groove 27 and enters the suction chamber 21 from the suction port 19.

[0036] In addition, a glue delivery port 20 is formed at the upper portion of the suction member 16, and the glue delivery port 20 is connected to the suction chamber 21. The output member 18 has an infusion port, and the glue delivery port 20 and the infusion port pipeline are connected; the glue pump 17 drives the glue to flow out of the suction chamber 21, and flows into the output member 18 through the glue delivery port 20 and the infusion port, and then the output member 18 outputs the glue to the outside.

[0037] The suction member 16 has a first inner tube 22 and a second inner tube 23. The first inner tube 22 connects the suction port 19 and the suction chamber 21, and the second inner tube 23 connects the suction chamber 21 and the glue delivery port 20. The suction member 16 includes a first one-way valve 24, which is disposed in the first inner tube 22, and the first one-way valve 24 prevents the glue liquid from flowing back from the suction chamber 21 to the liquid storage chamber 14. By arranging the first inner tube 22 and the first one-way valve 24, after the glue liquid is sucked into the suction chamber 21, it will not flow back from the suction port 19 to the liquid storage chamber 14.

[0038] In addition, the suction member 16 also includes a second one-way valve 25, which is placed in the second inner tube 23, and the second one-way valve 25 prevents the glue from flowing back from the glue delivery port 20 to the suction chamber 21; and the second inner tube 23 and the second one-way valve 25 are set so that the glue cannot flow back from the glue delivery port 20 to the suction chamber 21, and the structure is simple and effective.

[0039] In addition, the glue pump 17 includes a pump body 28 forming a traveling chamber and a pump shaft 30 for providing pressure. The pump body 28 is fixedly arranged relative to the suction piece 16, and the pump shaft 30 is embedded in the traveling chamber; an upper interface is formed at the upper part of the suction piece 16, and the upper interface passes through the suction chamber 21 along the top-down direction; a lower interface is formed at the lower part of the pump body 28 toward the suction piece 16, and the lower interface passes through the traveling chamber and is arranged opposite to the upper interface; a compression column 31 is provided at the lower part of the bottom of the pump shaft 30 toward the traveling chamber, and the compression column 31 is embedded in the suction chamber 21 from the upper interface and the lower interface. When the pump shaft 30 moves up and down, the lower part of the compression column 31 goes deeper into the suction chamber 21.

[0040] When the lower part of the compression column 31 goes deeper into the suction chamber 21, the space in the suction chamber 21 gradually decreases, causing the atmospheric pressure in the chamber to increase, so that the glue liquid is compressed and moves from the suction chamber 21 through the second one-way valve 25 to the glue delivery port 20, and then output from the suction member 16 to the output member 18.

[0041] In addition, an overflow groove is formed at the lower part of the compression column 31, so as to prevent excessive pressure on the glue liquid when the compression column 31 gradually moves downward.

[0042] A return spring 29 is connected between the lower surface of the pump shaft 30 and the bottom of the traveling chamber. The return spring 29 drives the pump shaft 30 to move away from the bottom of the traveling chamber, thereby driving the compression column 31 to gradually move upward. At this time, the atmospheric pressure in the suction chamber 21 gradually decreases, and the glue is sucked into the suction chamber 21 from the suction port 19 through the first inner tube 22 and the first one-way valve 24.

[0043] The conveying structure 15 with a simple structure also includes a motor 32 and an extension rod 33 connected to the motor 32. A contact block 34 is provided on the upper part of the pump shaft 30, and the extension rod 33 abuts against the contact block 34. When the motor 32 is running, the extension rod 33 is driven by the motor 32 to press the contact block 34, the pump shaft 30 is pressed downward, and the lower part of the compression column 31 goes deep into the suction chamber 21.

[0044] The extension rod 33 has a contact rod 35 at one end facing the pump shaft 30, and the other end of the extension rod 33 is connected to the motor; the contact block 34 has a contact surface arranged obliquely from bottom to top, and when the motor 32 drives the extension rod 33 to rotate, the contact rod 35 is pressed from the lower part of the contact surface to the upper part of the contact surface, and the contact block 34 is pressed downward and pushes the pump shaft 30 to move downward; when the contact rod 35 is separated from the contact surface, the pump shaft 30 is driven by the reset spring 29 to move away from the bottom of the traveling chamber.

[0045] The two contact blocks 34 are symmetrically arranged on the upper part of the pump shaft 30, and the two contact rods 35 are symmetrically connected to the extension rod 33; a reset space is formed between the two contact blocks 34. When the contact rod 35 rotates to the reset space and disengages from the contact surface, the pump shaft 30 moves upward, and the compression column 31 is driven by the reset spring 29 to move upward; at this time, the internal pressure of the suction chamber 21 is reduced, so that the glue liquid is sucked from the suction port 19.

[0046] In addition, an infusion tube 36 and an output tube 37 are formed inside the output component 18. The output component 18 has an input port and an output port. The input port is connected to the infusion tube 36, and the output port is connected to the output tube 37. The infusion tube 36 and the output tube 37 are connected and connected to each other. The glue enters the output tube 37 from the infusion tube 36 and flows out from the output port.

[0047] Moreover, a shunt tube 38 is formed inside the output member 18, and the output member 18 has a shunt port, which is connected to the shunt tube 38, and the shunt tube 38 intersects with the infusion tube 36 and is connected to form an intersection cavity 42; the upper part of the output member 18 has a control hole, and the control hole penetrates from top to bottom to the intersection cavity 42; the control device 12 includes a control block 41, and the control block 41 is embedded in the intersection cavity 42 from the control hole, and the control block 41 controls the flow rate to flow into the shunt tube 38.

[0048] The control block 41 has a diversion gap 39 and a buffer cavity 40 , and the diversion gap 39 is connected to the buffer cavity 40 to form a diversion channel; when the diversion channel is connected to the infusion tube 36 and the diversion tube 38 at the same time, the glue is diverted to the diversion tube 38 .

[0049] The control device 12 also includes a control column 43, the lower part of the control column 43 is connected to the control block 41, the upper part of the control column 43 passes through the control device 12 to be higher than the upper surface of the control device 12, and is formed with a screwing end 44 for screwing the control column 43. When the screwing end 44 is screwed, the control column 43 drives the control block 41 to rotate and makes the shunt channel connect to the infusion tube 36 and the shunt tube 38 at the same time, so that the glue is shunted into the shunt tube 38.

[0050] There is another embodiment, a flow control structure with easy operation, which is used in a glue coating machine, and includes a control block 41, a control column 43 and an output member 18, wherein the lower portion of the control column 43 is connected to the control block 41, and the upper portion of the control block 41 forms a screwing head for screwing; an infusion tube 36, a shunt tube 38 and an output tube 37 are formed inside the output member 18, the output member 18 has an input port connected to the infusion tube 36, an output port connected to the output tube 37 and a shunt port connected to the shunt tube 38, and the output tube 37 is connected and connected to the infusion tube 36; a control hole is provided at the upper portion of the output member 18, the infusion tube 36 and the shunt tube 38 are connected and connected to form a junction cavity 42, the control hole penetrates to the junction cavity 42, and the control block 41 is embedded in the junction cavity 42 from the control hole; the control block 41 has a shunt channel, and when the screwing head is screwed, the shunt channel rotates to connect the shunt tube 38 and the infusion tube 36.

When the screw head on the control column 43 is screwed, the shunt channel of the control block 41 is connected to the infusion tube 36 and the shunt tube 38 at the same time, and the glue enters the shunt tube 38, thereby controlling the glue flow entering the output tube 37.

[0052] The junction of the output tube 37 and the infusion tube 36 is located between the input port and the intersection cavity 42 ; before the glue flows to the intersection cavity 42 , it flows out from the output tube 37 .

[0053] The control block 41 is hollow to form a buffer cavity 40, and the partition gap connects the buffer cavity 40, and the length and width of the partition gap are smaller than the diameter of the infusion tube 36; when the partition gap is only connected to the infusion tube 36, after the glue flows in the infusion tube 36 to the buffer cavity 40, the glue is blocked and flows back.

[0055] The infusion tube 36 and the shunt tube 38 intersect at an angle to form an intersection; the separation notch and the buffer chamber 40 form a shunt channel; the separation notch forms a cutting surface, and when the cutting surface faces the intersection, the shunt channel connects the infusion tube 36 and the shunt tube 38; by screwing the screw head on the control column 43, the control block 41 can be rotated, so that the shunt channel connects the infusion tube 36 and the shunt tube 38 at the same time.

[0056] In addition, the infusion tube 36 and the shunt tube 38 are arranged horizontally, wherein the infusion tube 36 extends along the length direction of the output member 18, and the shunt tube 38 extends along the width direction of the output member 18; the diameter of the output tube 37 is smaller than the diameters of the shunt channel and the shunt tube 38; the output tube 37 is arranged along the vertical direction; and it is difficult for the glue to flow into the output tube 37.

[0057] A loading hole 45 penetrating the output member 18 is formed at the front of the output member 18 . The output port is located on the hole wall of the loading hole 45 . The infusion tube 36 , the output tube 37 and the shunt tube 38 are located above the output port and do not intersect with the loading hole 45 .

[0058] In addition, the flow control structure which is easy to operate includes a first limit block 56 and a second limit block 56, and the control column 43 has a horizontally arranged limit rod 47; the limit rod 47 rotates forward and backward on the horizontal plane between the first limit block 56 and the second limit block 56, and when the limit rod 47 rotates forward to touch the first limit block 56, the shunt channel is no longer connected to the shunt tube 38, and the dividing gap is located inside the infusion tube 36; when the limit rod 47 rotates reversely to touch the second limit block 56, the shunt channel is connected to the shunt tube 38 and the infusion tube 36 at the same time, and the flow entering the shunt tube 38 is the largest at this time.

[0059] The liquid storage device 11 includes a shell 26, which is hollow to form a liquid storage chamber 14; a through hole 46 is formed on the outer wall of the shell 26 and penetrates to the liquid storage chamber 14, the front of the output member 18 is connected to the wall of the liquid storage chamber 14, and the loading hole 45 is arranged opposite to the through hole 46, and the input port and the diversion port are located at the rear of the output member 18.

[0060] The first limiting block 56 and the second limiting block 56 are fixedly connected to the cavity wall of the liquid storage cavity 14 .

[0061] In another embodiment, the liquid storage device 11 includes a liquid level window structure 48, which is used for a glue coating machine. The liquid level window structure 48 includes an adapter 49 and a glass tube 50. The glue coating machine has a shell 26, and the shell 26 is hollow to form a liquid storage chamber 14 for storing glue, and the adapter 49 is hollow to form a adapter chamber 52; the adapter 49 has a horizontally arranged insertion column 51, and the end of the insertion column 51 extending toward the liquid storage chamber 14 is formed with a liquid level hole, and the liquid level hole is connected to the adapter chamber 52; the shell 26 has an insertion hole that penetrates to the liquid storage chamber 14, and the insertion column 51 is inserted into the liquid storage chamber 14 through the insertion hole; the glass tube 50 is formed with an overflow port toward the lower part of the adapter 49, and the upper part of the adapter 49 has a docking port, which is connected to the adapter chamber 52, and the glass tube 50 is connected to the adapter 49 and the docking port is located in the glass tube 50.

The adapter 49 has an insertion column 51 and an adapter chamber 52 is formed inside the adapter 49. The insertion column 51 has a liquid level hole and the liquid level hole is connected to the adapter chamber 52. The upper part of the adapter 49 has a docking block 58, and a docking port connected to the adapter chamber 52 is formed on the docking block 58. The glass tube 50 can be inserted into the adapter chamber 52 from the docking port, and the glass tube 50 has an overflow port. When there is glue liquid in the liquid storage chamber 14, the glue liquid can flow from the liquid level hole to the adapter chamber 52 and enter the glass tube 50 from the overflow port, so as to facilitate the observation of the glue liquid height.

[0063] The liquid level window structure 48 for the glue coating machine includes a shielding body 53, a mounting opening is formed at the lower portion of the shielding body 53, a mounting cavity is formed in the hollow portion of the shielding body 53, the mounting opening is connected to the mounting cavity, the glass tube 50 is inserted into the mounting cavity from the mounting opening, and the lower portion of the shielding body 53 is connected to the docking block 58; thus, the shielding body 53 plays a role in fixing the glass tube 50. Since problems may occur if the glue is exposed to light for too long, the shielding body 53 can also reduce the light exposure time of the glue in the glass tube 50.

[0064] However, in order to more conveniently observe the height of the glue, the shielding body 53 is formed with an observation hole 54 , which penetrates the outer surface of the shielding body 53 to the installation cavity; thus, the height of the glue can be observed through the observation hole 54 .

[0065] A blocking position is formed on the upper portion of the shielding body 53, and the observation hole 54 extends to the blocking position in a strip shape from bottom to top; the observation hole 54 is in a strip shape, and a larger observation range can be observed.

[0066] Moreover, the liquid level window structure 48 for the glue coating machine includes a sleeve 55, which is hollow to form a sleeve cavity, and a sleeve opening is formed at the lower end of the sleeve 55, and the sleeve opening is connected to the sleeve cavity; the diameter of the shielding body 53 is smaller than the diameter of the sleeve opening; the sleeve 55 can be sleeved on the shielding body 53, so that when it is necessary to observe the glue liquid height inside the liquid storage cavity 14, the sleeve 55 can be picked up to observe the glue liquid height.

[0067] In addition, a limit block 56 is provided on the inner wall of the sleeve cavity, and the diameter of the limit block 56 is smaller than the diameter of the observation hole 54; the limit block 56 is embedded in the observation hole 54; when the sleeve 55 is picked up, the limit block 56 can limit the sleeve 55 from being taken away, preventing the sleeve 55 from being lost, and is very convenient to use.

[0069] A docking block 58 is formed on the upper part of the docking piece, and a docking port is formed on the upper surface of the docking block 58 away from the adapter 49. The docking block 58 is arranged in a direction from top to bottom, with a larger size at the top and a smaller size at the bottom. Moreover, the inner tube diameter of the glass tube 50 is larger than the maximum diameter of the docking block 58. When the docking block 58 is embedded in the glass tube 50, the glue will not flow to the lower end of the glass tube 50, but will stay on the upper part of the docking block 58 because the docking block 58 is larger at the top and smaller at the bottom.

[0070] A sealing ring 59 is provided at the connection between the insertion column 51 and the shell 26, a sealing ring 59 is provided at the connection between the docking block 58 and the glass tube 50, and a sealing ring 59 is also provided at the connection between the insertion column 51 and the adapter 49, so as to prevent the glue from leaking out.

[0071] In addition, a shielding sheet 62 surrounding the shell 26 and a slide groove 63 formed around the shell 26 are provided on the outer surface of the shell 26. The shielding sheet 62 is placed in the slide groove 63. The shielding sheet 62 is provided with a straight through hole with the same diameter as the penetration hole 46. When the shielding sheet 62 is rotated and the straight through hole is arranged opposite to the penetration hole 46, the hose can be inserted into the loading hole 45; when it is not needed, the shielding sheet 62 can be rotated to cover the penetration hole 46.

[0072] Furthermore, a handle 60 is provided on the control device 12, so that the glue coating machine can be conveniently taken out using the handle 60.

[0073] The lower part of the shell 26 is connected to the base 61, and the shell 26 and the liquid level window structure 48 are fixed on the base 61. The base 61 is made of a heavier metal material, preferably iron, so that the overall center of gravity of the glue coating machine moves downward to prevent the glue coating machine from tipping over during use.
