Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, in particular to full-automatic ton-binding rope packaging equipment. Background Art

[0002] Ton bags are mainly used to load bulk powdery, granular or block materials. They include a bag body with a bag opening and a lifting ring. The bag must be sealed after filling to avoid leakage and escape during transportation.

[0003] At present, the main sealing methods for ton bags are sewing and tying ropes. Among them, tying ropes is a quick sealing method and is widely used. In order to ensure the efficiency of tying ropes, technical personnel in this field have developed a variety of tying rope machines. For example, Jiangsu Jinyi United Intelligent Manufacturing Co., Ltd., Anqiu Boyang Machinery Manufacturing Co., Ltd., Sanwei Hanjie Machinery (Shandong) Co., Ltd., etc. have manufactured fully automatic ton bag tying equipment, including a conveyor belt. The conveyor bag is equipped with a closing module and a tying rope module. The closing module first clamps the bag mouth of the ton bag horizontally, and then extrude it into a column, and then ties it through the tying rope module. The tying rope module is a tying rope machine, which can realize fully automatic tying ropes for ton bags with fast working speed and high stability.

[0004] In the process of horizontally clamping the bag opening of the ton bag, the bag opening is clamped from both sides by the clamping arms, and the clamping arms clamp the bag opening by swinging or translation, thereby pre-shaping the bag opening. During use, due to the irregular initial shape of the bag opening, the state of the bag opening after closing is greatly deviated, resulting in poor stability during the tying process, and even leakage. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a fully automatic ton-bundling rope packaging device.

[0006] The present invention is achieved through the following technical solutions:

The corresponding surfaces of the two movable clamping blocks are processed with arc grooves, and the two arc grooves cooperate to shrink the bag opening.

[0008] Furthermore, the translation frame can drive the bag clamping rod to move to the discharge nozzle, and the translation frame and the conveyor belt can move synchronously.

[0009] Furthermore, the bag clamping rod, the clamping plate and the movable clamping block are distributed in sequence from top to bottom, and an arc-shaped unloading port is provided on the clamping plate, and the unloading port corresponds to the terminal position of the bag opening shrinkage.

[0010] Furthermore, the elastic buffer structure includes an elastic capsule body arranged on the inner side of the bag clamping rod. The elastic capsule body is in the shape of an elongated strip and distributed along the length direction of the bag clamping rod.

[0011] Furthermore, the elastic buffer structure includes a support tube, the bag clamping rod is a round rod, the end of the bag clamping rod is inserted into the support tube through a support bearing, a flip plate is fixed on the inner side of the bag clamping rod, and a limiting opening is processed at the end of the support tube. The end of the flip plate extends into the limiting opening, and the limiting opening limits the flipping angle of the flip plate. When the flip plate swings to the lower end of the limiting opening, the flip plate is in an initial position of 8-10° obliquely upward. When the flip plate flips to the upper end of the limiting opening, the flip plate is in a limited position of 45-60° obliquely upward.

[0012] Furthermore, the flip plate includes a steel mesh frame, and a rubber layer is coated on the outside of the steel mesh frame.

[0013] Furthermore, the bag clamping rod includes a support plate, a corrective portion is provided on the edge of the support plate that is inclined upward, a pressure plate is provided on the upper side of the support plate, and the elastic buffer structure includes a rubber plate arranged between the pressure plate and the support plate, and both sides of the rubber plate extend outside the pressure plate to form an extrusion head that cooperates with the bag opening, and the corrective portion corrects the extrusion head obliquely upward so that the extrusion head is in an oblique upward position in the initial state.

[0015] Furthermore, a friction layer is installed on the working surface of the extrusion head that cooperates with the bag opening.

[0016] The beneficial effects of the present invention are:

[0017] 1. The slide drives the translation frame to move the ton bag to the predetermined position. The bag clamping rod clamps the bag opening, which can make the bag opening have a good initial state, thereby providing a good foundation for the rope tying machine. Under the action of the elastic buffer structure and the elastic force of the bag opening itself, the bag clamping rod can clamp the bag opening, thereby ensuring the stability of the position between the bag opening and the bag clamping rod during the movement of the ton bag.

[0019] 3. The end of the flip plate first contacts the bag opening and clamps it, and the two bag clamping rods move closer to each other. The flip plate is stressed and flips upward. The bag clamping rod clamps the bag opening and pushes it upward, so that the bag opening is in an upward tensioned state. When the flip plate is further flipped to the upper end of the limit opening, it cannot continue to flip, and the clamping force on the bag opening increases rapidly, thereby ensuring the stability of the bag opening clamping. In the process of clamping the bag opening, the bag opening is further shaped, and the bag clamping rod can be better protected, so that the force on the bag clamping rod is evenly increased.

[0030] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] Example 1

[0033] like Figure 1-5 As shown, a fully automatic ton bag rope packaging equipment includes a conveyor belt 1, which is a roller conveyor belt, thereby ensuring the supporting strength of the ton bag 2. The ton bag 2 is positioned by the friction between the conveyor belt 1 and the ton bag 2, so that the ton bag 2 can move in a straight line, and thus better cooperate with the closing device and rope tying machine 8 on the conveyor belt 1. The conveyor belt 1 extends to the lower end of the discharge nozzle 4. The rope tying machine 8 uses the LXDZGS-02A rope tying machine of Suizhou Huajian Drying Equipment Co., Ltd., which can automatically perform rope winding and bundling.

[0034] The conveyor belt 1 is provided with a closing device, which includes a pre-forming device, which includes a slide mounted on the side of the conveyor belt 1, a translation frame 6 is mounted on the slide, and a servo slide 5 is selected for the slide, so that the stroke can be accurately controlled. Two bag clamping rods 7 are mounted on the translation frame 6, and the bag clamping rod 7 is driven to move by a cylinder 16, which is mounted on the translation frame 6. An elastic buffer structure that matches the bag opening 3 is mounted on the bag clamping rod 7, and the elastic buffer structure includes an elastic capsule 18 mounted on the inner side of the bag clamping rod 7. The elastic capsule 1 8 is made of polyethylene material and is in the shape of a long strip. It is distributed along the length direction of the bag clamping rod 7. The translation frame 6 can drive the bag clamping rod 7 to move to the discharge nozzle 4. The servo slide 5 drives the translation frame 6 and the conveyor belt 1 to move synchronously. The bag clamping rod 7 is connected to the piston rod of the cylinder 16 through the bending rod 20. During the movement of the bag clamping rod 7, the elastic capsule 18 is deformed, increasing the contact area with the bag opening 3, thereby making the bag clamping more stable. The bag clamping rod is made of a rectangular tube, which provides an attachment surface for the elastic capsule 18. The elastic capsule 18 and the rectangular tube are bonded by an adhesive.

[0035] The closing device also includes a shrinking device installed at the rope tying machine 8, which includes two horizontal splints 9, a clamping opening formed between the two splints 9, the splint 9 is connected to a second cylinder 11, and the two splints 9 are driven to move closer or farther away by the second cylinder 11, the second cylinder 11 is connected to a fixed seat 10, and then fixedly connected to the side of the conveyor belt 1, a guide column 12 for guiding and supporting the splint 9 is installed on the fixed seat 10, and the guide column 12 is connected to the fixed seat 10 through a linear bearing, thereby ensuring that the splint 9 moves stably, the splint 9 is connected to a connecting seat 13 that cooperates with the second cylinder 11, and the cross section of the connecting seat 13 is L-shaped. The first wing of 3 is parallel to the splint 9, and the second wing of the connecting seat 13 is connected to the guide column 12, which is driven by the cylinder 2 11. It can provide a buffer during the extrusion process to prevent the splint 9 from being deformed due to excessive force. The splint 9 and the bag opening 3 are rounded to avoid scratching the bag opening 3. A movable clamp 15 is also installed on the lower side of the splint 9. The two splints 9 are both equipped with movable clamps 15. The movable clamp 15 is driven to move by the rodless cylinder 14. The moving direction of the movable clamp 15 is parallel to the length direction of the clamp. The corresponding surfaces of the two movable clamps 15 are processed with arc grooves 19, and the two arc grooves 19 cooperate to shrink the bag opening 3.

[0036] During the working process, the bag clamping rod 7, the clamping plate 9 and the moving clamping block 15 are arranged in sequence from top to bottom, and the ton bag 2 is placed at the predetermined position of the conveyor belt 1. The conveyor belt 1 drives the ton bag 2 to move to the discharge nozzle 4 of the injection machine. The conveyor belt 1 pauses, and the support bag opening 3 is opened to inject material into the ton bag 2. After the injection is completed, the slide drives the translation frame 6 to move the ton bag 2 to the predetermined position. The cylinder 16 drives the bag clamping rod 7 to clamp the bag opening 3, and the discharge nozzle 4 rises and separates from the bag opening 3. The conveyor belt 1 and the slide move synchronously. The ton bag 2 is transported to the rope tying machine 8, and the cylinder 2 11 is activated to clamp the lower end of the bag opening 3 at the clamping plate 9. The rodless cylinder 14 is activated to move the clamping block 15 to shrink the bag opening 3 through the arc groove 19. During the shrinking process, the cylinder 16 is activated to separate the bag clamping rod 7 from the bag opening 3 to avoid interference with the operation of the rope tying machine 8. After the rope tying is completed, the rodless cylinder 14 is reset, and the cylinder 2 11 is reset. After the rope tying is completed, the bag opening 3 falls under the action of its own weight, and the slide drives the translation frame 6 to reset, and then the next cycle is carried out.

[0037] The ton bag 2 is placed at a predetermined position on the conveyor belt 1. When the bag opening 3 is supported by the discharge nozzle 4, the slide drives the translation frame 6 to move the ton bag 2 to the predetermined position. The cylinder 16 drives the bag clamping rod 7 to clamp the bag opening 3, which can make the bag opening 3 have a good initial state, thereby providing a good foundation for the rope tying machine 8 to tie the rope. The position of the bag clamping rod 7 is lower than the discharge nozzle 4, and the difference is 3-4cm, thereby avoiding interference with the discharge nozzle 4. Under the action of the elastic buffer structure and the elastic force of the bag opening 3 itself, the bag clamping rod 7 can clamp the bag opening 3, thereby ensuring the stability of the position between the bag opening 3 and the bag clamping rod 7 during the movement of the ton bag.

[0038] After the ton bag 2 moves to the rope tying machine 8, the cylinder 2 11 is actuated to the middle position of the splint 9 clamping the bag opening 3. At this time, the bag opening 3 on the upper side of the movable slider is clamped. When the movable clamping block 15 is actuated, the bag opening 3 can be evenly stressed, thereby reducing the offset. At the end of the shrinking action, the deformation of the bag opening 3 exerts a greater force on the bag clamping rod 7. During the shrinking process, the cylinder 16 is actuated to separate the bag clamping rod 7 from the bag opening 3, which can protect the bag clamping rod 7 and has little effect on the shrinking effect. After the bag clamping rod 7 is separated from the bag opening 3, the movable clamping block 15 and the splint 9 still clamp the bag opening 3 to shape the bag opening 3. They are released after the rope tying machine 8 completes its work to ensure the quality of the rope tying.

[0039] During the test, we tried to move the translation frame 6 and the bag clamping rod 7 out before tying the bag. However, since the bag clamping rod 7 was lower than the highest point of the bag opening 3, the movement of the bag clamping rod 7 would push the bag opening 3, causing the bag opening 3 to deviate and affecting the tying effect.

[0040] During the test, it was found that when the movable clamping block 15 was working, a large lateral thrust was generated in the process of the bag opening 3 being squeezed and compressed. When the lateral thrust acted on the splint 9, the splint 9 was easily deformed. By reducing the driving air pressure of the control cylinder 2 11, the cylinder 2 11 can form an elastic buffer, but the clamping force on the bag opening 3 becomes weaker, and the bag opening 3 cannot be clamped stably. In this embodiment, an arc-shaped unloading port 17 is processed on the splint 9, and the unloading port 17 corresponds to the end position of the bag opening 3 shrinking. At the unloading port 17, the bag opening 3 can unload the force laterally, thereby reducing the pressure on the splint 9, and at the same time, the elastic force to the surrounding areas after the bag opening 3 shrinks can be evenly dispersed, and the columnar bag opening 3 formed has a more neat appearance.

[0041] Example 2

[0042] like Figure 6-8As shown, a fully automatic ton-wrapped rope packaging equipment is different from Example 1 in that the elastic buffer structure includes a support tube 21 installed at the end of the bending rod 20. For ease of production, the bending rod 20 and the support tube 21 are integrally bent from a stainless steel tube and have high anti-deformation strength. The bag clamping rod 7 is a round rod, and the end of the bag clamping rod 7 is inserted into the support tube 21 through a support bearing 24. There are two support bearings 24, thereby improving the support stability of the bag clamping rod 7. A flip plate 23 is fixed to the inner side of the bag clamping rod 7. The width of the flip plate 23 is 20-30 mm. The flip plate 23 includes a wire mesh frame, and a wire mesh frame is covered on the outside. The rubber layer makes the flip plate 23 elastic. A limiting opening 22 is processed at the end of the support tube 21. The end of the flip plate 23 extends into the limiting opening 22. The limiting opening 22 limits the flip angle of the flip plate 23. When the flip plate 23 swings to the lower end of the limiting opening 22, the flip plate 23 is in an initial position of 8-10 degrees upward. At this initial position, it can provide lateral thrust. When the force increases, it will automatically flip upward. When the flip plate 23 flips to the upper end of the limiting opening 22, the flip plate 23 is in a limited position of 45-60 degrees upward. It can no longer continue to flip upward and can automatically flip downward.

[0043] When the two bag clamping rods 7 are moved closer to each other, the end of the flip plate 23 first contacts the bag opening 3 and clamps it. When the two bag clamping rods 7 are moved closer to each other, the flip plate 23 is stressed and flips upward. The bag clamping rods 7 clamp the bag opening 3 and push the bag opening 3 upward, so that the bag opening 3 is in an upwardly stretched state. When the flip plate 23 is further flipped to the upper end of the limit opening 22, it cannot continue to flip, and the clamping force on the bag opening 3 increases rapidly, thereby ensuring the stability of the clamping of the bag opening 3. When the cylinder 16 drives the two bag clamping rods 7 to disengage from the bag opening 3, the flip plate 23 automatically flips downward and resets.

[0044] Compared with Example 1, the elastic buffer structure provided in this embodiment can further shape the bag opening 3 during the process of clamping the bag opening 3, and can better protect the bag clamping rod 7, so that the force on the bag clamping rod 7 is evenly increased. The disadvantage is that the flip plate 23 is easily deformed and damaged, and needs to be replaced and maintained regularly.

[0045] Example 3

[0046] like Figure 9As shown, a fully automatic ton-wrapped rope packaging equipment is different from Example 1-2 in that the bag clamping rod 7 includes a support plate 30, which is an aluminum alloy plate. The edge of the support plate 30 is bent upward to form an obliquely upward orthopedic part. A pressure plate 25 is installed on the upper side of the support plate 30 through a connecting bolt 29. The elastic buffer structure includes a rubber plate 26 installed between the pressure plate 25 and the support plate 30. The rubber plate 26 is vulcanized rubber. Both sides of the rubber plate 26 extend to the outside of the pressure plate 25 to form an extrusion head 27 that cooperates with the bag opening 3. The thickness of the extrusion head 27 gradually decreases from the outside to the inside. During use, the deformation speed can be gradually reduced, thereby ensuring the clamping stability of the bag opening 3. The minimum thickness of the extrusion head 27 is 5-6 mm, thereby ensuring sufficient anti-deformation strength. The lower end surface of 25 is formed with a downward pressing portion, and the cross-section of the pressing portion is a downward arc, corresponding to the middle position of the rubber plate 26. A friction layer 28 is installed on the working surface of the extrusion head 27 that cooperates with the bag opening 3. The friction layer 28 is a silicone rubber layer with a thickness of 1-2mm, which can be quickly extruded and deformed to increase the friction between the bag opening 3. The corrective portion corrects the extrusion head 27 obliquely upward so that the extrusion head 27 is in an oblique upward state in the initial state, and further bends and deforms upward after cooperating with the bag opening 3 for extrusion. The pressing portion can increase the extrusion force between the pressure plate 25 and the rubber plate 26, and can cooperate with the corrective portion to make the extrusion head 27 deform obliquely upward. In addition, the pressing portion can also improve the bending and deformation resistance of the pressure plate 25, and the corrective portion can improve the bending and deformation resistance of the support plate 30.

[0047] The extrusion heads 27 on both sides of the bag clamping rod 7 are arranged symmetrically. After one side is damaged, the bag clamping rod 7 is rotated to use the other side, thereby increasing the service life. Compared with Example 2, the bag clamping rod 7 provided in this embodiment has a reduced shaping stroke for the bag opening 3, but its service life is significantly increased.

[0048] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
