Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hot melt glue packaging, in particular to a PUR hot melt glue filling and packaging system. BACKGROUND

[0002] PUR hot melt glue is full name for moisture curing reaction type polyurethane hot melt glue, its action mechanism is that polyurethane prepolymer reacts with moisture in the air, and forms stable chemical structure through curing and crosslinking. Because of the special reaction mechanism of PUR hot melt glue, the packaging of PUR hot melt glue is a very important link.

[0003] Because the PUR hot melt glue is non-toxic and odorless, so in the existing PUR hot melt glue filling and packaging system, the aluminum bag is first placed in the barrel by manual, then the aluminum bag in the barrel is straightened by manual holding the metal frame, then the opening end of the aluminum bag is straightened, then the barrel is placed on the conveying belt, after the barrel reaches the bottom of the glue filling machine following the conveying belt, the glue filling machine is started, the PUR hot melt glue in molten state is directly poured into the barrel covered with the aluminum bag, after the glue filling is completed, the barrel continues to move to the bottom of the sealing assembly following the conveying belt, the opening end of the aluminum bag is closed by manual, then the closed aluminum bag is put into the sealing assembly, the sealing assembly performs vacuum treatment on the inside of the aluminum bag, and then nitrogen is added into the barrel, so that the barrel is in a state of no air and water vapor at last.

[0004] In the actual operation process, for smaller barrels, the selection of aluminum bags is also relatively small, so one person can place and straighten the aluminum bag, but for larger barrels, the aluminum bags used are relatively large, so two or more people are needed to place the aluminum bags, and then the aluminum bags in the barrel are arranged by manual holding the metal frame matched with the barrel, so as to make the outer wall of the aluminum bag adhere to the inner wall of the barrel and reduce the wrinkles of the aluminum bag, but in the long-term working process, in addition to the fact that iron products are relatively heavy, this not only increases the working strength of the workers, but also reduces the working efficiency of the workers after they feel tired, if the working efficiency is to be maintained, the workers need to be replaced, so double or more workers need to be arranged at the same post, which increases the production cost.

[0005] Therefore, the PUR hot melt glue filling and packaging system is proposed to solve the problems of increasing labor cost and low efficiency of the PUR hot melt glue filling and packaging system caused by manual operation in the prior art. SUMMARY

[0006] The purpose of the present application is to provide a PUR hot melt glue filling and packaging system to solve the problem of low efficiency of the PUR hot melt glue filling and packaging system caused by long-term manual placement and straightening of the aluminum bag body by workers.

[0007] To achieve the above object, the present application provides the following technical solutions:

[0008] The system for filling and packaging PUR hot melt adhesive comprises a conveying assembly, a barrel body, a sealing assembly, a glue filling assembly and an aluminum bag body, further comprises a mounting frame, a cylinder, a mounting plate, a top cover, a slot type bridge, a suction cylinder, a support, a transfer cylinder, an aluminum bag placing mechanism, a driving mechanism, a fitting mechanism, a shrinking mechanism, a shielding structure and a closing mechanism, the cylinder is installed at the bottom end of the mounting frame, the mounting plate is connected with the output end of the cylinder, the slot type bridge is installed at the top end of the mounting plate and the top cover respectively, the suction cylinder is installed at the bottom end of the top cover, the support is connected between the mounting frame and the mounting plate, the transfer cylinder is movably installed on the support, the cylinder drives the suction cylinder to move up and down and pass through five points a, b, c, d and e in turn, when moving from a to b, the mounting plate drives the support and the transfer cylinder to move down, when moving from b to c, the support stops moving, and the driving mechanism drives the transfer cylinder to translate to below the suction cylinder, when moving from c to d, the transfer cylinder stops moving, and the mounting plate, the top cover and the suction cylinder continue to move down through the transfer cylinder, when moving from d to e, the suction cylinder moves to the bottom end of the barrel body, the shrinking mechanism drives the top cover to close at the top end of the barrel body, and the fitting mechanism fits the aluminum bag body with the inner wall of the barrel body; when moving from e to d, the glue filling assembly fills glue into the aluminum bag body through the shielding structure, when moving from d to c, the mounting plate, the top cover and the suction cylinder move above the transfer cylinder through the transfer cylinder, when moving from c to b, the closing mechanism closes the opening of the aluminum bag body and the driving mechanism drives the transfer cylinder to move below the aluminum bag placing mechanism, when moving from b to a, the support is driven to move up, and the transfer cylinder adsorbs the outermost aluminum bag body of the aluminum bag placing mechanism to the inner wall.

[0009] In the above scheme, when the PUR hot melt adhesive needs to be filled, the aluminum bag body needs to be placed in the barrel body, the aluminum bag body can be pre-installed layer by layer on the outer wall of the conical frame, then the suction cylinder drives the transfer cylinder to rise under the action of the cylinder, the outermost aluminum bag body of the conical frame can be adsorbed and transferred, then the suction cylinder and the transfer cylinder are driven to descend under the action of the cylinder, in the process of continuous descent, the transfer cylinder changes from descending to translating, and then moves below the suction cylinder, under the action of the cylinder, the transfer cylinder stops moving, the suction cylinder drives the aluminum bag body to continue to descend, passes through the transfer cylinder and enters the barrel body, and then the aluminum bag body is placed, then the barrel body is sealed and pressurized, the outer wall of the aluminum bag body can be fitted with the inner wall of the barrel body, then the suction cylinder is driven to rise from the barrel body under the action of the cylinder, and the glue filling mechanism is lowered to fill glue, after the glue filling is completed, the third telescopic frame and the clamping plate can be inclined under the action of the cylinder, the opening of the aluminum bag body is flattened, only one cylinder is used to control the operation of each process, which not only saves labor and reduces the working intensity of workers, but also improves the glue filling efficiency of the PUR hot melt adhesive.

[0010] Optionally, the aluminum bag body is placed, and the smoothing work before the aluminum bag body is sealed can be operated manually or mechanically, but manual operation of each process of the PUR hot melt adhesive increases the work intensity of workers, and long-term work may even reduce the work efficiency of the PUR hot melt adhesive filling and packaging. If you want to maintain the work efficiency, you need to replace the workers, which will increase the cost of manual labor, so manual operation of filling and packaging is not selected.

[0011] Preferably, the aluminum bag placing mechanism comprises a conical frame, a first telescopic frame, a hook, a chain and a positioning ring, the conical frame and the first telescopic frame are both installed at the bottom end of the support, the first telescopic frame is coaxially arranged with the conical frame, the hook is installed at the movable end of the first telescopic frame, the chain is sleeved on the outer wall of the hook, the bottom end of the chain is installed at the top end of the positioning ring, the inner wall of the positioning ring is in the shape of a circular truncated cone, the inner diameter of the positioning ring is smaller than the diameter of the top end of the conical frame, the top end opening of the transfer cylinder is in the shape of a circular truncated cone, the slope of the inner wall of the top end of the transfer cylinder, the slope of the outer wall of the conical frame and the slope of the inner wall of the positioning ring are consistent, and the bottom end inner diameter of the transfer cylinder is greater than the top end outer diameter of the conical frame.

[0012] In the above scheme, the aluminum bag body is sleeved on the outer wall of the conical frame layer by layer, as the number of aluminum bag bodies increases, the positioning ring moves downward, and at the same time stretches the first telescopic frame, so that the positioning ring can always clamp and position the outermost aluminum bag body, then the transfer cylinder is lowered after adsorbing the outermost aluminum bag body, which can stretch the first telescopic frame to a certain extent, but under the elasticity of the first telescopic frame body, the positioning ring will not produce a large displacement, only the outermost aluminum bag body can be separated, and at the same time the inner aluminum bag body can be clamped and positioned. At this time, due to the decrease in the number of aluminum bag bodies, the overall thickness between the conical frame and the aluminum bag body will decrease slightly, so that the positioning ring will shrink a certain height under the elasticity of the first telescopic frame, so that the outermost aluminum bag body can be clamped and positioned regardless of the remaining number of aluminum bag bodies.

[0013] Optionally, placing the aluminum bag body in the transfer cylinder can be done by placing a large number of aluminum bag bodies on the conical frame at one time or placing the aluminum bag bodies one by one on the shelf by hand. If the aluminum bag bodies are placed one by one on the shelf above the transfer cylinder by hand, a flow line mode will be formed, and long-term work will make workers feel tedious, thereby reducing the enthusiasm of work, and manual operation will also reduce the work efficiency, so a large number of aluminum bag bodies are sleeved on the conical frame at one time, which can avoid manual participation within a certain period of time.

[0014] Preferably, the driving mechanism comprises a first rack, a first spur gear, a first rotating shaft, a first bevel gear, a second bevel gear, a second rotating shaft and a transfer unit, the first rack is installed on one side of the mounting plate, the inner part of the support is respectively provided with a rotating groove and a first mounting groove, the first spur gear is rotatably installed on the inner wall of the rotating groove, the first rack is in meshing connection with the first spur gear, the first rotating shaft is symmetrically installed on the two sides of the first spur gear, one end of the first rotating shaft is rotatably installed on the inner wall of the first mounting groove, the first bevel gear is installed on the outer wall of the first rotating shaft, the second bevel gear is in meshing connection with the first bevel gear, the second rotating shaft is installed at the bottom end of the second bevel gear, and the bottom end of the second rotating shaft is also provided with a second bevel gear, and the second bevel gear is connected with the transfer unit.

[0016] In the above scheme, the movement of the transfer cylinder is linked with the lifting of the adsorption cylinder, which can ensure that the adsorption cylinder drives the movement of the transfer barrel during the movement, and the synchronous movement between the adsorption cylinder and the transfer cylinder can avoid errors in the work process, increase the mechanization performance of the device, and simplify the operation of the device.

[0017] Optionally, the transfer cylinder and the fitting mechanism can be driven by a cylinder to operate in linkage or separately driven by a cylinder, but the transfer cylinder driven by a separate cylinder cannot ensure that the movement of the adsorption cylinder and the movement of the transfer cylinder remain synchronous, which may have a bad impact on the placement of the aluminum bag body to some extent, and therefore a separate cylinder is not selected to drive the transfer cylinder.

[0023] In the above scheme, by increasing the sealing of the barrel, the aluminum bag body can be pushed after the placement is completed, the local outer wall of the aluminum bag body is attached to the inner wall of the barrel, and then the air is filled into the barrel after the sealing of the barrel is increased, so as to realize the pressurization of the barrel. Because the pressure inside and outside the barrel is not the same, the outer wall of the aluminum bag body is completely attached to the inner wall of the barrel, so as to avoid the existence of air between the aluminum bag bodies due to the existence of wrinkles, and to avoid the influence of air on the storage of PUR hot melt adhesive.

[0024] Optionally, the aluminum bag body is placed on the inner wall of the barrel before filling, which can be operated mechanically or manually. However, manual operation may cause the aluminum bag body to not completely attach to the inner wall of the barrel, and may cause the aluminum bag body to have wrinkles, which may cause air to remain in the aluminum bag body during vacuum operation, which may affect the storage of PUR hot melt adhesive. At the same time, the smoothing of the aluminum bag body by workers is operated by a metal frame matched with the barrel, which increases the working strength of the workers, so that the workers do not smooth the aluminum bag body in the barrel.

[0025] Preferably, the closing mechanism comprises a rectangular groove, a first guide rod, a telescopic spring, a sliding block, a third connecting rod, a third fixed seat, a fourth fixed seat, a fourth connecting rod, a second rack, a second straight gear, a fourth rotating shaft, a fifth fixed seat, a third telescopic frame, a clamping plate and a second telescopic frame. The rectangular groove is arranged in the installation plate. The first guide rod is arranged on the inner wall of the rectangular groove.

One telescopic spring is connected to one side of the sliding block. One end of the telescopic spring is arranged on the inner wall of the rectangular groove. The third connecting rod is rotatably arranged on the top end of the sliding block. The third fixed seat is rotatably arranged on one end of the third connecting rod.

The elasticity of the second telescopic frame is greater than that of the telescopic spring. The length of the third telescopic frame is greater than the height of the adsorption cylinder. The third telescopic frame has a telescopic function.

[0026] In the above scheme, after the aluminum bag body is placed, the adsorption cylinder rises, when the third mounting seat contacts the second telescopic frame, the angle between the two third connecting rods starts to increase, and under the cooperation of the second rack and the second spur gear, the two third telescopic frames can be tilted towards each other, with the rising of the clamping plates, the distance between the two clamping plates becomes smaller and smaller, and at the same time, the opened aluminum bag body opening can be shrunk, when the angle between the two third connecting rods becomes the maximum, the distance between the two clamping plates starts to be fixed, but at this time the aluminum bag body has been closed.

[0027] Optionally, when the aluminum bag body is closed, mechanical operation or manual operation can be used, but if manual operation is used, the worker needs to be in the same position all the time to close the opening, if the aluminum bag body is large, the worker may not be able to shrink the opening of the aluminum bag body at one time, so the worker needs to move back and forth, which will soon make the worker feel tired, so manual closing is not used.

[0028] Compared with the prior art, the beneficial effects of the present application are:

[0029] 1. The aluminum bag body is adsorbed by the adsorption cylinder, then the adsorption cylinder is controlled to descend by a cylinder, so that the aluminum bag body can be moved into the barrel for placement, the adsorption cylinder is controlled to expand and then seal and pressurize the inside of the aluminum bag body in the barrel, the aluminum bag body can be controlled to gradually collide, so that the adhesion of the outer wall of the aluminum bag body to the inner wall of the barrel can be improved, the existence of wrinkles can be avoided to some extent, air remaining in the aluminum bag body during glue filling can be avoided, the influence of the existence of air on the preservation of PUR hot melt glue can be avoided, the transfer barrel and the adsorption cylinder are synchronously moved by the cylinder, then the inside of the aluminum bag body in the barrel is sealed and pressurized by the pump body, manual operation can be reduced, the working intensity of the worker can be reduced, the glue filling efficiency of the PUR hot melt glue can be improved, and the labor cost can be reduced.

[0030] 2. The installation plate is controlled to rise and fall by the cylinder, which can drive the first rack to rise and fall, the first rack can drive the first spur gear to rotate during the rising and falling process, so that the transfer cylinder and the adsorption cylinder can be synchronously moved, since the diameters of the first spur gear, the first bevel gear, the second bevel gear and the third bevel gear gradually decrease, the function of variable speed can be realized, the transfer barrel and the adsorption cylinder can be synchronously lifted, and can also be quickly translated, the cylinder used to push the transfer barrel to translate can be reduced, the operation of the PUR hot melt glue filling and packaging system can be simplified, and the cost can be reduced.

[0031] 3. The third fixed seat and the second telescopic frame are in contact or away from each other by controlling the lifting of the transfer cylinder by the air cylinder, the angle between the two third telescopic frames can be adjusted, when the third fixed seat rises, the third fixed seat is in contact with the second telescopic frame, so that the opening of the aluminum bag body after filling is closed, manual sealing can be avoided, manual labor can be saved, and the use cost of the PUR hot melt glue filling packaging system can be further saved.

The third extension frame 713 has an extension function. When the glue filling is completed, the installation plate 8 is driven to rise under the action of the air cylinder 7. When the installation plate 8 rises, the third fixed seat 706 is driven to rise, and then contacts the second extension frame 715 to press the third fixed seat 706, so that the inclination angle of the two third connecting rods 705 is increased, and then the sliding block 704 slides on the first guide rod 702, and the extension spring 703 is pressed. In the process of sliding, the sliding block 704 can drive the second rack 709 to move, and the second rack 709 can drive the second spur gear 710 to rotate, so that the third extension frame 713 is driven to rotate. When the two third extension frames 713 gradually change from the vertical state to the inclined state, the clamping plate 714 can drive the aluminum bag body 5 to shrink. When the two clamping plates 714 are in contact, the opening of the aluminum bag body 5 can be shrunk. Then, with the continuous rising of the installation plate 8, the sliding block 704 does not continue to slide, but the second extension frame 715 still continues to compress, so that the clamping plate 714 can be prevented from continuing to adhere. Since the third extension frame 713 has a certain elasticity,The third telescopic frame 713 can prevent the clamping plate 714 from being unable to continue to descend after being in contact with the conveying assembly 1, so that the top cover 9 cannot enter the barrel body 2.

[0054] Working principle: Before filling work, the staff prepares work, puts the aluminum bag body 5 through the positioning ring 205, and then puts it on the outer wall of the conical frame 201 layer by layer, and then the positioning ring 205 moves upward under the action of the first telescopic frame 202, and then through the arc-shaped setting of the inner wall, the aluminum bag body 5 can be pressed and positioned, then the barrel body 2 is placed on the conveying assembly 1, under the action of the conveying assembly 1, the barrel body 2 can be moved to the below of the suction cylinder 11, then the cylinder 7 is started, the cylinder 7 drives the mounting plate 8 to rise, because one end of the second cross rod 19 on one side of the mounting plate 8 is located in the inner wall top end of the third groove 17, in the process of rising of the mounting plate 8, the second cross rod 19 can drive the support 12 to rise, in the process of rising of the support 12, the transfer cylinder 13 can be driven to rise, in the process of rising of the transfer cylinder 13, the outermost aluminum bag body 5 will enter the inside of the transfer cylinder 13, then the vacuum pipe 3004 on the outer wall of the transfer cylinder 13 is connected with the vacuum pump outside, then the vacuum pump is started, the vacuum pump extracts the air in the inside of the transfer cylinder 13 through the vacuum pipe 3004, so that negative pressure is generated, the aluminum bag body 5 can be adsorbed on the inner wall of the transfer cylinder 13, and the opening end of the aluminum bag body 5 is sucked by the boss part at the top end of the transfer cylinder 13, so that the opening of the aluminum bag body 5 is prevented from being wrinkled;

[0055] The cylinder 7 is started again, the cylinder 7 can drive the mounting plate 8 to descend, in the process of descending of the mounting plate 8, the suction cylinder 11 can be driven to descend, and at the same time the support 12 can be driven to descend through the second cross rod 19, in the process of descending of the support 12, the first cross rod 16 can be driven to slide on the second guide rod 15, when the first cross rod 16 drives the support 12 to move to the bottom end of the inner wall of the second groove 14, the support 12 stops moving,

In the process of rotating, the third bevel gear 3001 can drive the screw 3002 to rotate. In the process of rotating, the screw 3002 can drive the threaded clamp block 3003 to move towards the adsorption cylinder 11. In the process of moving, the threaded clamp block 3003 can simultaneously drive the transfer cylinder 13 and the aluminum bag body 5 to move towards the adsorption cylinder 11. When the transfer cylinder 13 is about to coincide with the adsorption cylinder 11, the teeth on one side of the first rack 301 begin to decrease, and the tooth spacing becomes larger, thereby reducing the rotation speed of the first spur gear 302 and the moving speed of the transfer cylinder 13, which can ensure that the transfer cylinder 13 moves at a gentle speed at the end of the stroke, preventing the aluminum bag body 5 from deforming in an emergency stop state;
