Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and particularly to a packaging equipment for spinning production. Background Art

[0002] In the field of spinning production, the packaging operation after the formation of yarn bobbins is a key process to ensure the safe transportation of products. In the traditional packaging process, operators need to manually put plastic packaging bags around the yarn bobbins and then use heat-sealing equipment for encapsulation. However, the existing technology has the following significant defects:

[0003] The degree of manual intervention is high. The bagging process relies on manual operation. Workers need to repeatedly perform actions such as holding the bag open and putting it on. The single-shift repeated operation reaches hundreds of times. This not only limits the packaging efficiency to the manual speed but also is more likely to cause quality accidents such as scratches on the surface of the yarn bobbins due to fatigue operation. At the same time, it is difficult to ensure the precise alignment of the packaging bag and the yarn bobbin during manual bagging, which will lead to problems such as skewed sealing and incomplete local sealing in the subsequent automated heat-sealing process.

[0004] Chinese Patent CN118683997B discloses a packaging equipment for all-cotton Lyocell blended yarn, which includes a frame. A material placing mechanism, a material transferring mechanism, and a palletizing mechanism are sequentially arranged on the frame. The material placing mechanism includes a material placing cylinder. A placing plate is arranged on the piston rod of the material placing cylinder. The placing plate is penetrated with a limiting groove for the bottom of the yarn tube to be inserted. The length of the limiting groove extends along the length direction of the piston rod of the material placing cylinder. The placing plate is used to receive the yarn tubes sent out by the packaging machine. The material transferring mechanism is used to transfer the yarn tubes into the palletizing mechanism batch by batch. The palletizing mechanism includes an installation frame and a palletizing frame. A lifting plate is arranged to move up and down vertically inside the installation frame. The palletizing frame is arranged on the lifting plate, and the lifting plate is used to drive the palletizing frame to move up and down. The palletizing frame is used to batch-receive the yarn tubes transferred out from the material transferring mechanism. This application has the effect of improving the packaging efficiency and being able to meet the mass production requirements of the factory.

[0005] The above patent uses a material transferring mechanism and a palletizing mechanism to achieve palletizing, but does not package the spun yarn. Subsequently, manual bagging is still required, and the bagging efficiency is low. At the same time, the tail of the bag body is not opened during manual bagging, which is likely to cause difficulties in loading the spun yarn into the bag when the spun yarn enters the bag, and there is a risk that the spun yarn will squeeze the bag body off during bagging. Summary of the Invention

[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to propose a packaging equipment for spinning production. Through the bagging assembly of the present invention, the function of automatic bagging is realized, and at the same time, the bag opening is blown to blow open the tail of the bag body, thereby avoiding the problem of improper installation of the tail of the bag body; through the setting of the clamping assembly, the bag opening is clamped, thereby preventing the high-pressure gas from blowing off the bag body when the air nozzle sprays air at the bag opening; at the same time, through the clamping of the second suction cup and the first wedge block of the clamping assembly, it is ensured that the bag body will not be clamped until it is fully opened, thereby avoiding the bag body being clamped during the opening process, resulting in tearing.

[0021] (1) The present invention sets a bagging assembly at the feeding end of the packaging conveyor belt, and sucks the bag body at the bottom of the bagging box through the first suction cup of the bag suction member, and then descends. After one side of the bag body opening is pulled out of the bagging box, the mounting plate is driven to approach the bagging box through the contraction of the telescopic rod.

When the third wedge block slides upward, it drives the second wedge block to slide inward toward the mounting frame, so that the bag opening is opened. At the same time, the second suction cup on the second wedge block and the end of the first wedge block located on the inner side of the mounting frame abut against the support plate to clamp and fix the bag opening, thereby clamping the bag opening and preventing high-pressure gas from blowing off the bag body when the air nozzle sprays air at the bag opening. At the same time, the clamping of the second suction cup and the first wedge block of the clamping assembly ensures that the bag body is clamped only after it is fully opened, thereby avoiding the bag body being clamped during the opening process, resulting in tearing.

[0023] (3) The packaging equipment of the present invention uses a feeding conveyor belt to transport the yarn, which is sorted on a discharging conveyor belt. After the sorting is completed, a batch of yarn is pushed into the bag body by a pushing cylinder and sent to the next procedure for sealing. The whole process does not require manual operation, which greatly improves the packaging efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] As Figures 1 to 6 shown, a packaging device for spinning production includes a feeding conveyor belt 100 and a discharging conveyor belt 200 provided on a frame 400.

[0034] The bagging box 510 is provided with a bagging assembly 600 near the discharge side of the discharge conveyor belt 200, and the clamping assemblies 700 are symmetrically installed on both sides of the mounting frame 500, and the clamping assembly 700 and the bagging assembly 600 are arranged in linkage; a pushing cylinder 900 is also installed on the frame 400, and the pushing cylinder 900 is arranged above the discharge conveyor belt 200 and located in the feeding direction of the packaging conveyor belt 300.

[0035] The discharge conveyor belt 200 is used to receive the materials delivered by the feeding conveyor belt 100, and arrange them one by one. After arranging to a predetermined number, the pushing cylinder 900 is used to push them onto the packaging conveyor belt 300 under the bagging box 510; specifically, the conveying speed and frequency of the discharge conveyor belt 200, the receiving feeding conveyor belt 100 and the packaging conveyor belt 300, and the pushing of the pushing cylinder can be controlled by a control system, which are all existing technologies and will not be elaborated here.

[0036] In this embodiment, the bagging assembly 600 includes a bag suction piece 690 arranged below the bagging box 510, and mounting plates 610 arranged on both sides of the bagging box 510, and the mounting plates 610 slide horizontally on the mounting frame 500; a bidirectional screw 620 is rotatably connected between the two mounting plates 610, a motor 660 is fixed on one side of the mounting plate 610, and the output shaft of the motor 660 is fixedly connected to one end of the bidirectional screw 620; two support plates 630 for relative movement are screwed on the bidirectional screw 620; limit rods 640 are provided on both sides of the support plate 630; and blowing pieces 650 are connected between the mounting plates 610 on both sides and their corresponding support plates 630.

[0037] The bag suction member 690 sucks a bag at the bottom of the bagging box 510. After one side of the bag is sucked, the bagging box 510 is pulled out. At this time, the telescopic cylinder 512 is driven to contract to slide the mounting plate 610 to one side of the bagging box 510. After the sliding is completed, the lower end of the support plate 630 extends into the bag opening, and the driving motor 660 drives the two support plates 630 to slide to the two sides of the mounting frame 500 through the rotation of the bidirectional screw 620 and the setting of the limit rod 640. The bag opening is opened to realize the function of automatic bagging. At the same time, when the support plate 630 slides outward, the airbag 651 is squeezed and the internal air is released. The gas in the gas cylinder 653 is opened and fixed, and the gas in the gas cylinder 653 reaches the critical pressure value. The safety valve 655 opens automatically, and the air nozzle 654 sprays air at the bag opening to blow open the bag body away from the end of the bag opening, so that the tail of the bag body is completely separated from the bagging box 510. The present invention realizes the function of automatic bagging through the bagging assembly 600, and blows air to the bag opening at the same time, avoiding the problem of improper installation of the tail of the bag body. No manual operation is required in the whole process, which greatly saves manpower and improves the work efficiency of packaging.

[0038] In this embodiment, the blowing member 650 includes an airbag 651 fixedly connected between the mounting plate 610 and the support plate 630, a one-way air inlet valve is installed on the airbag 651, the airbag 651 is located on one side of the mounting plate 610 and is connected to a ventilation pipe 652, the other end of the ventilation pipe 652 is connected to a gas cylinder 653, and the gas cylinder 653 is installed on the side of the mounting plate 610 close to the support plate 630; the gas cylinder 653 is provided with a gas nozzle 654, and a safety valve 655 is installed on the gas nozzle 654.

[0039] Before spinning and bagging, the support plate 630 slides outward, and the internal gas of the airbag 651 is discharged to the gas cylinder 653 to spray air to the bag opening, and the bag body away from the end of the bag opening is blown open, so that the tail of the bag body is completely separated from the bagging box 510; after the spinning and bagging is completed, the motor 660 is driven to reverse, and the support plates 630 on both sides are moved closer to the center of the packaging conveyor belt 300 through the reversal of the motor 660, driving the airbag 651 to be pulled open. At this time, there is no gas inside the airbag 651. After being pulled open, the one-way valve on the airbag 651 is forced to open under the pressure difference between the inside and outside of the airbag 651, and the external gas is inhaled. After the inhalation is completed, the one-way valve is closed to prepare for the next bagging; the motor 660 is reversed, and the support plates 630 on both sides are moved closer to the center of the packaging conveyor belt 300, and the bag body is loosened and sent to the next procedure for sealing through the packaging conveyor belt 300.

[0040] In this embodiment, the bag suction member 690 includes a fixing plate 691 fixed on the inner side of the mounting frame, the fixing plate 691 is located below the packaging conveyor belt 300, a telescopic rod 692 is vertically mounted on the fixing plate 691, a first suction cup 693 is fixed on the top of the telescopic rod 692, a long strip opening is opened on the packaging conveyor belt 300, and the first suction cup 693 passes through the long strip opening under the extension and retraction of the telescopic rod 692 to pull down the bottom surface of the bag body in the bagging box 510 one by one.

[0041] The first suction cup 693 is used to suck the bag body, and the rise and fall of the telescopic rod 692 is used to suck the bag body and release the bag body. Specifically, when in use, the telescopic rod 692 is driven to rise, and after the bag body is sucked by the first suction cup 693, the telescopic rod 692 is driven to descend to the packaging conveyor belt 300, so that the top of the first suction cup 693 is flush with the upper surface of the packaging conveyor belt 300. After the support plate 630 sinks into the bag opening and the bag opening is opened, the telescopic rod 692 can be driven to further descend, so that the first suction cup 693 is separated from the bag body, and the bag is sucked.

[0042] In this embodiment, the clamping assembly 700 includes a first wedge block 710 and a second wedge block 720 that slide horizontally on the mounting frame 500, and the first wedge block 710 and the second wedge block 720 are arranged vertically; a connecting plate 530 is further fixed on the outer side wall of the mounting frame 500 between the first wedge block 710 and the second wedge block 720, and a third wedge block 730 is vertically slidably connected to the connecting plate 530; a limiting ring 731 is provided on the third wedge block 730, and the limiting ring 731 is located above the connecting plate 530; a butting ring 721 is provided on the second wedge block 720, and a spring 740 is further sleeved on the second wedge block 720, and the spring 740 is located between the butting ring 721 and the outer side wall of the mounting frame 500;

[0043] One end of the first wedge block 710 located outside the mounting frame 500 is in sliding fit with the bottom of the third wedge block 730, and one end of the second wedge block 720 located outside the mounting frame 500 is in sliding fit with the top of the third wedge block 730.

[0044] See Figure 6 , on the outer side of the mounting frame 500, the first wedge block 710 and the third wedge block 730 are provided with opposite slopes, and both ends of the second wedge block 720 are provided with slopes that cooperate with the first wedge block 710 and the third wedge block 730; when the support plate 630 slides outward to the first wedge block 710, the first wedge block 710 is pushed to slide outward. At this time, the first wedge block 710 pushes the third wedge block 730 to slide upward. When sliding, the third wedge block 730 pushes the second wedge block 720 to slide inward and compresses the spring 740. After the support plate 630 slides outward in place, one end of the first wedge block 710 abuts against the support plate 630, and the second suction cup 750 of the second wedge block 720 sucks the bag body and abuts against the support plate 630, realizing the clamping of the bag mouth end, preventing the high-pressure gas from blowing off the bag body when the air nozzle 654 jets air at the bag mouth. At the same time, through the clamping of the second suction cup 750 and the first wedge block 710 of the clamping assembly 700, it is ensured that the bag body will be clamped only after being fully opened, avoiding the problem of tearing caused by the bag body being clamped during the opening process.

[0045] In this embodiment, a sloping feeding plate 410 is installed between the feeding conveyor belt 100 and the discharging conveyor belt 200, and the sloping feeding plate 410 is fixed on the machine frame 400; a guide rod 110 is installed on the feeding conveyor belt 100, the guide rod 110 is fixed on the machine frame 400, and the front end of the guide rod 110 extends to the discharging conveyor belt 200.

[0046] The guiding rod 110 is used for guiding, and the slope-shaped feeding plate 410 is used for the feeding connection between the feeding conveyor belt 100 and the discharging conveyor belt 200. It should be noted that the feeding conveyor belt 100 is slightly higher than the discharging conveyor belt 200 for convenient feeding.

[0047] In this embodiment, a receiving plate 550 is provided at the feeding end of the mounting frame 500. One side of the receiving plate 550 is attached to the discharging end of the discharging conveyor belt 200, and the other side of the receiving plate 550 is located above the packaging conveyor belt 300; a plurality of positioning baffles 210 are evenly distributed on the discharging conveyor belt 200.

[0048] The receiving plate 550 facilitates the feeding connection, and the side of the receiving plate 550 close to the packaging conveyor belt 300 is located above the packaging conveyor belt 300, which can prevent the problem of belt jamming when the spun yarn enters the bag, resulting in unsuccessful bagging.

[0049] In this embodiment, the support plate 630 is an L-shaped plate, and one end of the support plate 630 is located below the bagging box 510. The L-shaped plate facilitates the support plate 630 to extend into the bag opening to ensure the opening of the bag opening.

[0050] In this embodiment, a telescopic cylinder 512 is connected between the mounting plate 610 and the bagging box 510, and the mounting plate 610 horizontally slides on the mounting frame 500 through the expansion and contraction of the telescopic cylinder 512.

[0051] In this embodiment, a second suction cup 750 is fixed at one end inside the mounting frame 500 where the second wedge-shaped block 720 is located.

[0052] The working principle of a packaging device for spinning production according to the present invention is as follows:

[0053] During use, the telescopic rod 692 is driven to rise, and a bag body at the bottom of the bagging box 510 is sucked by the first suction cup 693. After one side of the bag body is sucked, the bagging box 510 is pulled out, and the telescopic rod 692 is driven to descend to the position of the packaging conveyor belt 300, so that the top of the first suction cup 693 is flush with the upper surface of the packaging conveyor belt 300; the telescopic cylinder 512 is driven to contract, and the mounting plate 610 is slid towards the bagging box 510. After the sliding is completed, the lower end of the support plate 630 extends into the bag opening, the motor 660 is driven, and through the rotation of the bidirectional screw rod 620 and the setting of the limiting rod 640, the two support plates 630 are driven to slide towards both sides of the mounting frame 500, and the bag opening is opened. Then, the telescopic rod 692 can be further driven to descend to complete the function of automatic bag loading;

[0054] Meanwhile, when the support plate 630 slides outward to the first wedge block 710, it pushes the first wedge block 710 to slide outward. At this time, the first wedge block 710 pushes the third wedge block 730 to slide upward. When sliding, the third wedge block 730 pushes the second wedge block 720 to slide inward to the mounting bracket 500 and compresses the spring 740. After the support plate 630 slides outward in place, one end of the first wedge block 710 abuts against the support plate 630, and the second suction cup 750 of the second wedge block 720 sucks the bag body and abuts against the support plate 630, realizing the clamping of the bag mouth end.

[0055] Further, when the support plate 630 slides outward, the airbag 651 is squeezed, and the internal gas is discharged into the gas cylinder 653 through the air pipe 652. When the support plate 630 slides to both sides of the mounting bracket 500, the bag mouth is opened and fixed. At this time, the gas in the gas cylinder 653 reaches the pressure critical value, and the safety valve 655 automatically opens, and the nozzle 654 is aligned with the bag mouth to spray gas, blowing open the bag body at the end far from the bag mouth, realizing that the tail of the bag body is completely separated from the bagging box 510.

[0056] At this time, after a set of arranged spinning is pushed into the bag body through the bag mouth by using the pushing cylinder 900 and the loading is completed, the driving motor 660 rotates reversely. Through the reverse rotation of the motor 660, the support plates 630 on both sides move closer to the center of the packaging conveyor belt 300. The bag body is released by the support plates 630 and the clamping assembly 700 and is sent to the next process for sealing through the packaging conveyor belt 300.

[0057] When the support plate 630 moves closer to the center of the packaging conveyor belt 300, the airbag 651 is stretched. At this time, there is no gas inside the airbag 651. After being pulled open, under the pressure difference between the inside and outside of the airbag 651, the one-way valve on the airbag 651 is forced to open, inhaling external gas. After the inhalation is completed, the one-way valve closes, preparing for the next bagging.

[0058] Although the present invention has been disclosed above with embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments with equivalent changes by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the scope of the technical solution of the present invention.
