Description

Technical Field

[0001] The present application relates to the technical field of cargo storage and transportation, and in particular to an anti-drip glue system for a palletizing anti-slip agent coating machine. Background Art

[0002] During the process of palletizing goods for storage or transportation, in order to make the bags stacked on the pallet more stable, prevent the bags from slipping and the entire bag stack from collapsing, and meet the needs of on-site transportation, storage and long-distance transportation of palletized goods in the three-dimensional warehouse, more and more users achieve this function by roller-coating palletizing anti-slip agents on the bags. Therefore, the use of palletizing glue coating machines is becoming more and more widespread.

[0003] If glue drips from the gluing machine, the dripping glue will fall onto the conveyor belt, causing a waste of resources. At the same time, it will increase the friction on the belt surface, making it impossible to complete the normal bag pushing action, resulting in poor stacking operation and reduced work efficiency. In addition, due to the increased friction between the material bags and the belt, the equipment will wear out faster, reducing the service life of the belt and thus increasing costs.

[0004] In order to prevent glue from dripping when glue coating is not required or the glue coating machine is shut down, the roller coating glue coating machines currently on the market all adopt a check valve installed at the end of the glue outlet pipe on the glue coating head to solve the problem. However, when the staff replaces the glue barrel, if the glue filling operation is improper, the pressure in the pipeline is not fully released, and the residual pressure in the pipeline still exceeds the maximum locking force of the check valve. At this time, the glue continues to flow out until it gradually reaches a balance, resulting in glue dripping, so higher requirements are placed on the staff's operation; at the same time, when the glue coating machine has been working for a long time and at a high frequency, the pressure in the pipeline is in a state greater than the maximum locking force of the check valve. If it is shut down at this time, the pressure in the pipeline needs to be slowly released through the outflow of glue until it reaches a balance with the locking force of the check valve, and the problem of glue dripping will also occur.

[0006] The present application provides a palletizing anti-slip agent coating machine anti-drip glue system adopts the following technical solutions:

[0007] A glue-drip prevention system for a palletizing anti-slip agent gluing machine comprises a packaging bag conveying mechanism, a gluing device installed on the packaging bag conveying mechanism, an anti-glue dripping solenoid valve arranged on the gluing device, a lifting device for controlling the vertical position of the gluing device, and a control system for controlling the anti-glue dripping solenoid valve, wherein the anti-glue dripping solenoid valve is used to control the flow of glue, the lifting device comprises a mounting frame installed on the packaging line conveying mechanism, a lifting box fixedly connected to the mounting frame, a rotating motor arranged on a side of the lifting box away from the packaging line conveying mechanism, a first screw fixedly connected to the output shaft of the rotating motor, and a connecting block threadedly connected to the first screw, and the gluing device is mounted on the connecting block.

[0008] By adopting the above technical solution, during use, when the packaging bag passes by, the staff adjusts the lifting device according to the volume of the material in the packaging bag, so that the glue coating roller can abut against the upper surface of the packaging bag and perform glue coating on the packaging bag. When the glue coating roller is lifted up, the induction switch generates a signal, and the control system controls the anti-drip glue solenoid valve to open, so that glue can flow out of the hose. Through signal control, the possibility of glue dripping when no glue coating is needed is reduced, thereby saving resources and improving work efficiency.

[0009] Optionally, the gluing device includes an installation box installed on the side of the connecting block away from the mounting frame, a glue box placed in the installation box, a bracket arranged on the installation box, an induction switch arranged on the bracket, a telescopic member with both ends hinged on the bracket, a gluing roller installed on the side of the bracket close to the packaging bag conveying mechanism, an auxiliary roller rotatably connected to the bracket, and a hose for conveying glue, and the side wall of the auxiliary roller abuts against the side wall of the gluing roller.

[0010] Optionally, the bracket includes a support plate installed on the side of the installation box away from the installation frame, an upper inclined plate fixedly connected to the side of the support plate away from the packaging bag conveying mechanism, a lower inclined plate hinged to the side of the support plate close to the packaging bag conveying mechanism, a mounting frame installed on the lower inclined plate, a first connecting shaft arranged on the installation frame, and a second connecting shaft arranged on the installation frame, the telescopic part is hinged between the installation frame and the upper inclined plate, the glue coating roller is rotatably connected to the first connecting shaft, and the auxiliary roller is rotatably connected to the second connecting shaft.

[0011] Optionally, the telescopic member includes a movable rod hinged on the side of the installation frame away from the packaging bag conveying mechanism, a sleeve hinged on the side of the upper inclined plate away from the installation box, a limit plate arranged on the movable rod, and a return spring arranged between the limit plate and the sleeve, the limit plate is located at one end of the movable rod close to the packaging bag conveying mechanism, the sleeve is sleeved on the movable rod, one end of the return spring is connected to the end of the sleeve, and the other end is connected to the limit plate.

[0012] By adopting the above technical solution, when in use, after the glue coating roller is lifted up by the packaging bag, the glue coating roller returns to its initial position under the action of the elastic force of the return spring.

[0013] Optionally, the gluing device further includes a vibration-damping component, which is used to increase the buffering force when the gluing roller contacts the surface of the packaging bag, thereby improving the flexibility of the gluing roller.

[0014] Optionally, the vibration damping assembly includes a first connecting ring arranged on the first connecting shaft, a second connecting ring sleeved on the first connecting ring, and a vibration damping spring arranged between the first connecting ring and the second connecting ring.

[0015] By adopting the above technical solution, when in use, when the glue coating roller contacts the surface of the packaging bag, the damping spring is compressed, so that the contact force between the glue coating roller and the packaging bag is enhanced, while the flexibility of the glue coating roller is improved.

[0016] Optionally, the gluing device further includes an adjusting component, and the adjusting component is used to adjust the relative position of the rubber hose and the gluing roller.

[0017] By adopting the above technical solution, when in use, the staff operates the adjustment component according to the surface area of ​​the packaging bag to adjust the relative position between the end of the hose and the glue roller, so that the packaging bag is fixed more firmly during stacking.

[0018] Optionally, the adjustment assembly includes a connecting plate installed on a side of the installation frame away from the packaging bag conveying mechanism, a sliding block slidably connected to the connecting plate, and a pushing cylinder for controlling the sliding of the sliding block.

[0019] By adopting the above technical solution, when in use, the staff starts the push cylinder to push the cylinder piston rod to extend, so that the sliding block moves, thereby changing the position of the hose.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. This application sets up an anti-drip glue solenoid valve and its corresponding control system. When a packaging bag passes by, the sensor switch sends a signal, and the control system controls the anti-drip glue solenoid valve to open, allowing the glue in the hose to flow out. When the packaging bag leaves, the glue roller returns to its initial position under the action of gravity and the elastic force of the return spring. At this time, the sensor switch signal disappears, and the control system controls the anti-drip glue solenoid valve to close, and the glue in the hose stops flowing out. Through signal transmission and control, the possibility of glue leakage in the glue applicator when gluing is not needed is reduced, saving resources, and at the same time reducing the damage to the packaging bag conveyor surface caused by glue dripping;

[0022] 2. This application provides a vibration reduction component so that when the packaging bag passes through the gluing roller, the gluing roller applies a certain pressure to the packaging bag, causing the material in the convex part of the packaging bag to transfer to the concave part, thereby making the gluing roller work more flexibly and improving the working efficiency of the gluing roller;

[0023] 3. This application sets an adjustment component so that the staff can adjust the position of the hose according to the surface area of ​​the packaging bag, making the gluing position of the gluing roller on the packaging bag more flexible and improving the stability of the packaging bags when stacking.

[0027] The following is combined with Figure 1-2 This application is described in further detail.

[0028] The embodiment of the present application discloses a palletizing anti-slip agent coating machine anti-drip glue system. Figure 1 A palletizing anti-slip agent gluing machine anti-drip glue system includes a bag conveying mechanism 1, a gluing device 2 mounted on the bag conveying mechanism 1, an anti-drip glue solenoid valve 3 disposed on the gluing device 2, a lifting device 4 for controlling the vertical movement of the gluing device 2, and a control system for controlling the anti-drip glue solenoid valve 3. The anti-drip glue solenoid valve 3 is used to control the flow of glue. The anti-drip glue solenoid valve 3 and the control system are both existing technical structures and are not further elaborated in this application.

[0029] The packaging bag conveying mechanism 1 includes a support frame 11 placed on the ground, a support frame 12 installed on the side of the support frame 11 away from the ground, and a belt conveyor 13 installed on the support frame 12. The belt conveyor 13 is a prior art and will not be elaborated in this application.

[0030] The lifting device 4 includes a mounting frame 41 installed on the side of the support frame 12 away from the ground, a lifting box 42 fixedly connected to the mounting frame 41, a rotating motor 43 arranged on the side of the lifting box 42 away from the packaging line conveying mechanism, a first screw 44 fixedly connected to the output shaft of the rotating motor 43, and a connecting block 45 threadedly connected to the first screw 44. The gluing device 2 is installed on the connecting block 45, and the connecting block 45 slides with the lifting box 42.

[0031] Reference Figure 1 and Figure 2 The gluing device 2 includes an installation box 21 installed on the side of the connecting block 45 away from the mounting frame 41, a glue box 22 placed in the installation box 21, a bracket 23 arranged on the installation box 21, a telescopic member 24 with both ends hinged on the bracket 23, an induction switch 25 arranged on the bracket 23, a gluing roller 26 installed on the side of the bracket 23 close to the packaging bag conveying mechanism 1, an auxiliary roller 27 rotatably connected to the bracket 23, and a hose 28 for conveying glue. The installation box 21 and the bracket 23 are both provided with connecting holes for the hose 28 to pass through.

[0032] During use, the staff operates the rotating motor 43 according to the volume of the packaging bag to be glued and the items contained in the packaging bag, so that the output shaft of the rotating motor 43 rotates, driving the first screw 44 to rotate, and the connecting block 45 threadedly connected to the first screw 44 moves along the length direction of the first screw 44, thereby adjusting the gluing device 2 to a suitable position so that the gluing device 2 can glue the surface of the packaging bag, thereby improving the gluing efficiency; when the belt conveyor 13 transports the packaging bag, the packaging bag applies an upward thrust to the gluing roller 26, so that the gluing roller 26 is lifted up, and the induction switch 25 generates a signal. After receiving the signal, the control system controls the anti-drip glue solenoid valve 3 to open, so that the glue in the hose 28 flows out. When the packaging bag leaves, under the action of gravity and the telescopic part 24, the glue roller 26 moves to the initial position, and the signal of the sensing switch 25 disappears. When the control system cannot receive the signal of the sensing switch 25, the control system controls the anti-drip glue solenoid valve 3 to close, so that the glue in the hose 28 stops flowing out. By using signals to control the flow of glue, the possibility of glue dripping is reduced, the waste of glue resources is reduced, and the impact of glue dripping on the belt conveyor 13 is reduced, thereby improving work efficiency.

[0033] Reference Figure 1 and Figure 2 The bracket 23 includes a support plate 231 installed on the side of the installation box 21 away from the installation frame 41, an upper inclined plate 232 fixedly connected to the side of the support plate 231 away from the packaging bag conveying mechanism 1, a lower inclined plate 233 hinged to the side of the support plate 231 close to the packaging bag conveying mechanism 1, a mounting frame 234 installed on the lower inclined plate 233, a first connecting shaft 235 fixedly connected to the mounting frame 234, and a second connecting shaft 236 fixedly connected to the mounting frame 234; wherein the telescopic member 24 is located between the mounting frame 234 and the upper inclined plate 232; the first connecting shaft 235 and the second connecting shaft 236 are both arranged along the length direction of the mounting frame 234, the glue coating roller 26 is rotatably connected to the first connecting shaft 235, and the auxiliary roller 27 is rotatably connected to the second connecting shaft 236.

[0034] Under normal circumstances, the side wall of the glue coating roller 26 abuts against the side wall of the auxiliary roller 27, and the rubber hose 28 is located between the glue coating roller 26 and the auxiliary roller 27 near one end of the packaging bag conveying mechanism. When the packaging bag passes by, the packaging bag drives the glue coating roller 26 to rotate, and the glue coating roller 26 drives the auxiliary roller 27 to rotate, so that the glue between the glue coating roller 26 and the auxiliary roller 27 rotates and smears around the peripheral wall of the glue coating roller 26, so that the glue coating roller 26 performs a glue coating operation on the surface of the packaging bag.

[0035] The telescopic member 24 includes a movable rod 241 hinged on the side of the mounting frame 234 away from the packaging bag conveying mechanism 1, a sleeve 242 hinged on the side of the upper inclined plate 232 away from the mounting box 21, a limiting plate 243 fixedly connected to the movable rod 241, and a return spring 244 arranged between the limiting plate 243 and the end of the sleeve 242. The limiting plate 243 is located at the end of the movable rod 241 close to the packaging bag conveying mechanism 1, the sleeve 242 is sleeved on the movable rod 241, one end of the return spring 244 is connected to the end of the sleeve 242, and the other end is fixedly connected to the limiting plate 243.

[0036] During use, when the packaging bag passes by, the packaging bag applies an upward thrust to the glue coating roller 26, the glue coating roller 26 is lifted upward, the lower inclined plate 233 rotates around its hinge axis, and the movable rod 241 moves into the sleeve 242. At this time, the reset spring 244 is compressed, causing the induction switch 25 to generate a signal, thereby allowing the control system to control the anti-drip glue solenoid valve 3 to open, and the glue in the hose 28 flows between the glue coating roller 26 and the auxiliary roller 27, and the glue coating roller 26 performs glue coating on the passing packaging bag.

[0037] Among them, the induction switch 25 can be a travel switch, so that under normal circumstances, the side wall of the sleeve 242 abuts against the travel switch, thereby controlling the anti-drip glue solenoid valve 3 to close; when the packaging bag passes by, the packaging bag exerts an upward force on the glue coating roller 26, so that the glue coating roller 26 is lifted up. At this time, the sleeve 242 will also rotate around the hinge axis with the upper inclined plate 232, so that the sleeve 242 is separated from the travel switch, and the anti-drip glue solenoid valve 3 can be controlled.

[0038] Reference Figure 1 and Figure 2 Since the packaging bags are easily deformed by external forces during transportation, when the packaging bags move to the bottom of the gluing device 2, bulges or pits appear on the upper surface of the packaging bags. When the gluing roller 26 performs the gluing operation, gaps in the glue traces appear on the upper surface of the packaging bags, resulting in insufficient glue coating on the surface of the packaging bags, and thus poor fixing effect between the packaging bags when the packaging bags are stacked.

[0039] In order to improve the gluing effect of the gluing roller 26 on the surface of the packaging bag, a vibration damping component 5 is provided between the first connecting shaft 235 and the gluing roller 26. The vibration damping component 5 is used to increase the buffering force when the gluing roller 26 contacts the surface of the packaging bag, thereby improving the flexibility of the gluing roller 26.

[0040] Reference Figure 2 The vibration damping assembly 5 includes a first connecting ring 51 arranged on the first connecting shaft 235 , a second connecting ring 52 sleeved on the first connecting ring 51 , and a vibration damping spring 53 arranged between the first connecting ring 51 and the second connecting ring 52 .

[0041] During use, the staff operates the lifting device 4 to adjust the glue coating roller 26 to a suitable position so that when the packaging bag passes by, the side wall of the glue coating roller 26 is pressed against the upper surface of the packaging bag. Under the elastic force of the vibration-damping spring 53, the glue coating roller 26 pushes the raised part of the packaging bag surface to the recessed part, making the packaging bag surface relatively flat, which is conducive to the gluing work of the packaging bag.

[0042] Reference Figure 1 and Figure 2 In order to increase the glue coating area of ​​the glue coating roller 26 on the surface of the packaging bag and make the position between the packaging bags more stable, two glue coating rollers 26 are provided, and two auxiliary rollers 27 are provided accordingly. The two glue coating rollers 26 are both located on the first connecting shaft 235, and the two auxiliary rollers 27 are both located on the second connecting shaft 236. Two rubber hoses 28 are arranged opposite to each other, and the ends of the two rubber hoses 28 are respectively located on the two glue coating rollers 26.

[0043] When in use, the two glue coating rollers 26 have two relative glue coating tracks on the surface of the packaging bag, which increases the glue coating area on the surface of the packaging bag, thereby improving the stability of the packaging bag.

[0044] Due to the different sizes of packaging bags, when the upper surface area of ​​the packaging bag is large, if the two gluing tracks are relatively concentrated, the fixing effect of the two relatively concentrated gluing tracks will be poorer than that of the two dispersed and symmetrical gluing tracks.

[0045] In order to be suitable for packaging bags of different sizes, an adjustment component 6 is provided on the mounting frame 234. The adjustment component 6 is used to adjust the relative position of the hose 28 and the glue coating roller 26. The adjustment component 6 includes a connecting plate 61 installed on the side of the mounting frame 234 away from the packaging bag conveying mechanism 1, a sliding block 62 slidably connected to the connecting plate 61, and a pushing cylinder 63 for controlling the sliding of the sliding block 62. A movable groove for the rubber hose 28 to pass through is provided on the connecting plate 61. The pushing cylinder 63 is installed on the inner wall of the mounting frame 234 and the telescopic direction is consistent with the movable groove. The piston rod of the pushing cylinder 63 is fixedly connected to the side wall of the sliding block 62.

[0046] During use, the staff operates the cylinder 63 according to the size of the packaging bag, adjusts the relative position of the hose 28 and the glue roller 26, so that the glue can be symmetrically applied to the upper surface of the packaging bag, making the position of the packaging bag more firmly fixed.

[0047] The implementation principle of the anti-drip glue system of the palletizing anti-slip agent gluing machine of the present application is as follows: when in use, the staff operates the lifting device 4 to adjust the position of the glue coating roller 26 in the vertical direction according to the volume of the material in the packaging bag, and operates the adjustment component 6 to adjust the relative position of the end of the hose 28 and the glue coating roller 26 according to the area of ​​the packaging bag. After the preparation work is completed, when the packaging bag passes by, the packaging bag applies an upward thrust to the glue coating roller 26. After the glue coating roller 26 is lifted up, the sensing switch 25 generates a signal. After receiving the signal, the control system opens the anti-drip glue solenoid valve 3, allowing the glue in the hose 28 to flow out. When the packaging bag leaves, under the action of the reset spring 244, the glue coating roller 26 moves to the initial position, and the signal of the sensing switch 25 disappears. When the control system cannot receive the signal of the sensing switch 25, the control system controls the anti-drip glue solenoid valve 3 to close. At this time, the glue in the hose 28 stops flowing out, and the operation is completed.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
