Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to an automatic closing device for anode powder packaging. Background Art

[0002] In the process of producing aluminum using electrolysis, a large amount of finished powder is produced in the anode workshop. This powder is discharged through the discharge port and packaged into packaging bags for storage, sale or standby.

[0003] In the process of packaging powder, the packaging bag needs to be placed at the feeding port for loading. After the powder is loaded, the packaging bag needs to be sealed to prevent the powder from escaping or leaking. Before sealing, the two sides of the bag opening of the packaging bag need to be squeezed inward so that the two sides of the bag opening of the packaging bag fit together to facilitate the sealing operation. To this end, when closing and sealing the bag opening, a splint provided with a hot melt device is generally used to perform the specific execution. While the two sides of the bag opening are clamped and closed by the splint, the hot melt device on the splint performs a hot melt sealing treatment on the bag opening. However, the sealing part of this packaging bag that has been hot-melt treated by the splint is linear, and the local sealing strength is not high, resulting in the bag opening of the packaging bag being very prone to leakage during the subsequent handling process.

[0004] To address the shortcomings of existing hot-melt seals, wire tying has been used instead. This method offers advantages over hot-melt sealing in that, after sealing, the bag openings are gathered and folded in an interlaced pattern, making them less likely to loosen or leak, effectively avoiding the drawbacks of hot-melt sealing. However, currently, tying the bag openings relies on operators manually twisting the ends of curved tying pins together. This operation is cumbersome, time-consuming, and labor-intensive. Therefore, a device that can automatically tie and seal the bags is needed to improve sealing efficiency. Utility Model Content

[0005] The utility model aims to provide an automatic closing device for anode powder packaging, so as to realize automatic closing and sealing of the bag opening of the packaging bag and improve the sealing efficiency of the packaging bag.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an automatic closing device for anode powder packaging, comprising a frame, a closing mechanism is provided on the frame, the closing mechanism comprises a driving member, a supporting platform and a pair of symmetrically distributed swing arms, the driving member is used to drive the supporting platform to move linearly, an arc-shaped notch is provided at the end of the supporting platform away from the driving member, the notch is used to carry arc-shaped binding nails for binding, two swing arms extend from one side of the driving member to the other side of the notch, and the middle parts of the two swing arms are rotatably connected to the supporting platform, and the ends of the two swing arms close to the notch are fixedly connected with arc-shaped clamping nozzles, and the clamping nozzles are located above the supporting platform; the swing arm is connected to a swing drive unit, the swing drive unit is used to drive the swing arm to swing so that the two clamping nozzles are offset from each other, the two swing arms are also connected to a reset member, and the middle parts of the two swing arms are away from each other and the two ends are close to each other.

[0007] The principle and advantages of this solution are: in this solution, the driving member drives the supporting platform, so that the clamping nozzle can be automatically moved to the bag opening of the packaging bag for tying. When tying, the binding nail is pre-placed at the notch of the supporting platform. After the clamping nozzle is moved to the bag opening of the packaging bag, the bag opening of the packaging bag enters the notch. At this time, the swing arm is driven by the swing driving unit to swing the swing arm. Since the middle of the swing arm is positioned on the supporting platform, the end of the swing arm away from the swing driving unit will swing in the opposite direction under the action of the lever, so that the two clamping nozzles move toward each other and resist each other. During the movement of the clamping nozzle, the two ends of the arc-shaped binding nail at the notch are squeezed inward, so that the binding nail changes from an arc to a ring, thereby automatically tying the bag opening. Through the structure in this solution, the automatic tying of the binding nail can be achieved without manual tying, which improves the working efficiency and sealing quality of tying and sealing.

[0008] Preferably, as an improvement, the swing drive unit includes a drive cylinder fixed on the support platform, the cylinder rod of the drive cylinder is connected to a swing control member, and the swing control member simultaneously abuts against the parts of the two swing arms close to the drive member.

[0009] Through the above solution, the swing control member is used to move linearly under the drive of the driving cylinder and counteract different parts of the swing arm, thereby achieving control of different swing degrees of the swing arm and further achieving automatic swing control of the clamping nozzle.

[0010] Preferably, as an improvement, the swing control member is a wheel rotatably connected to the cylinder rod of the driving cylinder, and there is one wheel, which simultaneously abuts against two swing arms; or there are two groups of wheels symmetrically distributed, and the two groups of wheels abut against two swing arms respectively.

[0011] Through the above solution, the cylinder drives the wheel to move, causing the wheel to push against the swing arm and swing the swing arm. While achieving the swing control of the swing arm, the wheel can rotate on the swing arm, thereby reducing the friction when the two are in contact, which is more conducive to the wheel's swing control of the swing arm. When there is only one wheel, one wheel pushes against both swing arms at the same time, so that the two swing arms can swing synchronously, and then the two clamping mouths can squeeze the two ends of the tying nail inward at the same time, which is beneficial to improving the quality of the tying. When there are two sets of wheels, the two sets of wheels push against the two swing arms respectively. This means that the wheel diameter does not need to be very large, which is more convenient for structural assembly and actual installation and use.

[0012] Preferably, as an improvement, the swing control member is a wedge fixedly connected to the cylinder rod of the driving cylinder, the diameter of the wedge facing the notch is larger than the other end, and both side ends of the wedge are provided with wedge surfaces and the wedge surfaces are against the two swing arms.

[0013] Through the above scheme, the wedge block is driven to move by driving the cylinder, so that the wedge block pushes the two swing arms to swing. Compared with the pushing structure and method of the wheel, the wedge surface of the swing control part has a larger area for contact with the swing arm, which is more conducive to the swing control of the swing arm.

[0014] Preferably, as an improvement, the swing control component includes a rack fixedly connected to the cylinder rod of the driving cylinder, a gear is meshed on the rack, a double-headed screw is coaxially fixedly connected to the gear, both ends of the double-headed screw are socketed and threadedly connected with a sliding sleeve, the sliding sleeve is set on the supporting platform for sliding along the axial direction of the double-headed screw, and a push block is fixedly connected to the sliding sleeve, and the two push blocks are respectively abutted against the two swing arms.

[0015] Through the above scheme, the transmission of the gear rack mechanism and the screw mechanism is utilized to make the driving cylinder drive the push block to move laterally and push the swing arm to make the swing arm swing. In this swing control method, since the push block does not follow the cylinder rod of the driving cylinder to move linearly along the axial direction of the cylinder rod, but only moves linearly along the radial direction of the cylinder rod in the original position, the area of contact and friction between the swing arm and the swing control part is smaller, which can reduce the area of wear caused by the swing control part on the swing arm, and is beneficial to extending the service life of the swing arm.

[0016] Preferably, as an improvement, a nailing position is provided on the supporting platform, and the cylinder rod of the driving cylinder is fixedly connected to a push handle. The nailing position is located between the notch and the push handle and is located on the moving path of the push handle. The push handle is used to push the binding nail from the nailing position to the notch.

[0017] With the above solution, the stapling position is used to place lashing nails to be used. When the driving cylinder is activated, the push handle moves and automatically pushes the lashing nails on the stapling position to the notch for use, thereby achieving automatic pushing of the lashing nails. The stapling position makes it easier to place lashing nails, avoiding the risk of lashing nails falling out of the notch or being pinched by the clamp when placing lashing nails directly in the notch, thus improving practicality.

[0018] Preferably, as an improvement, the tying mechanism also includes a nail rack for storing binding nails, the nail rack is fixed on the supporting platform, the nail rack has a horizontal part and a vertical part connected to each other, the horizontal part and the vertical part have a smooth transition, and the vertical part is located directly above the stapling position.

[0019] With this solution, the nail rack is used to arrange and place lashing nails for use, eliminating the need to add a new nail after each lashing. This allows the device to continuously perform packaging operations, making it more convenient for actual production use. By pushing the lashing nail along the nail rack, it moves from the horizontal portion to the vertical portion, where it automatically drops along the vertical portion to the stapling position, achieving automatic nailing.

[0020] Preferably, as an improvement, a nail pushing head is slidably provided on the nail rack, and the nail pushing head is used to push the binding nails to move along the nail rack, and a compression spring is connected between the nail pushing head and the nail rack.

[0021] With the above solution, the nail pusher is used to push the lashing nails arranged on the nail rack forward, so that the lashing nails can be dropped into the nailing positions one by one. This allows for automatic loading of lashing nails without manual pushing, facilitating actual production use. The compression spring is used to exert a continuous squeezing force on the nail pusher, enabling the nail pusher to continuously push the lashing nails.

[0022] Preferably, as an improvement, two guide nozzles are fixedly provided at one end of the supporting platform where the notch is provided, and the notch is located between the two guide nozzles.

[0023] Through the above solution, the guide nozzle is used to guide the bag opening when the bag opening moves into the notch, so that the bag opening of the bag can smoothly enter the notch and be completely and well tied, which is conducive to improving the tying quality of the bag opening.

[0024] Preferably, as an improvement, the tying mechanism is rotatably connected to the frame, a lifting cylinder is connected between the tying mechanism and the frame, and both ends of the lifting cylinder are rotatably connected to the frame and the tying mechanism respectively.

[0025] Through the above scheme, the jacking cylinder can flip the tying mechanism so that the tying mechanism can be in a vertical state when in standby state and a flat state when in use. In this way, when the packaging bag needs to be taken out from above, the tying mechanism can be changed to a vertical state, so that the tying mechanism will not hinder the removal of the packaging bag. At the same time, when the equipment is not needed, it is also easier to store the tying mechanism, reduce the width of the equipment, and facilitate the storage of the equipment.

[0033] The following is a detailed description of the present invention through specific embodiments, but the embodiments of the present invention are not limited thereto. Unless otherwise specified, the technical means used in the following embodiments are conventional means well known to those skilled in the art; the experimental methods used are conventional methods; and the materials and reagents used are all commercially available.

[0034] The figure marks in the drawings of the specification include: frame 1, mounting plate 2, lifting cylinder 3, control cylinder 4, notch 5, swing arm 6, clamping nozzle 7, reset part 8, guide nozzle 9, driving cylinder 10, wheel 11, nail rack 12, horizontal part 13, vertical part 14, nailing position 15, push handle 16, nail pushing head 17, wedge block 18, rack 19, gear 20, double-headed screw 21, sliding sleeve 22, push block 23, binding nail 24, and supporting platform 25.

[0035] Example 1

[0036] The automatic sealing device for anode powder packaging in this embodiment has a structure as follows: Figure 1 and Figure 2 As shown, it includes a frame 1, on which a tying mechanism is provided, and the tying mechanism includes a driving member, a supporting platform 25 and a pair of symmetrically distributed swing arms 6. A lifting cylinder 3 is connected between the tying mechanism and the frame 1, and the two ends of the lifting cylinder 3 are rotatably connected to the frame 1 and the tying mechanism respectively. Specifically, the driving member in this embodiment is a control cylinder 4, and a mounting plate 2 is rotatably connected to the frame 1 through a rotating shaft. The control cylinder 4 is fixed on the mounting plate 2, and the cylinder seat of the lifting cylinder 3 is rotatably connected to the frame 1. The cylinder rod of the lifting cylinder 3 is rotatably connected to the bottom of the mounting plate 2. In this way, through the operation of the lifting cylinder 3, the mounting plate 2 can be flipped on the frame 1 together with the tying mechanism, so that the tying mechanism can be transformed between a horizontal state and a vertical state.

[0037] The driving member (i.e., the control cylinder 4) is used to drive the linear motion of the carrier 25. In this embodiment, the carrier 25 is fixed on the cylinder rod of the control cylinder 4. In this way, the linear motion of the carrier 25 can be achieved by the operation of the control cylinder 4. Figure 2 An arc-shaped notch 5 is provided at the end of the supporting platform 25 away from the control cylinder 4. The notch 5 is used to carry the arc-shaped binding nails 24 for binding. Two swing arms 6 extend from one side of the control cylinder 4 to the side of the notch 5, and the middle parts of the two swing arms 6 are rotatably connected to the supporting platform 25 through a rotating shaft. An arc-shaped clamping nozzle 7 is fixedly connected to the end of the two swing arms 6 close to the notch 5, and the clamping nozzle 7 is located above the supporting platform 25.

[0038] The swing arm 6 is connected to a swing drive unit, which is used to drive the swing arm 6 to swing so that the two clamping nozzles 7 are aligned. The ends of the two swing arms 6 closest to the control cylinder 4 are also connected to a reset member 8. In this embodiment, the reset member 8 is a tension spring, with both ends of the tension spring connected to the ends of the two swing arms 6. Furthermore, the two swing arms 6 in this embodiment are bent, with the middle portions of the two swing arms 6 moving away from each other and the ends moving closer together. This allows one end of the swing arm 6 to swing under force, while the other end can swing in the opposite direction. Two guide nozzles 9 are fixed to the end of the support platform 25 where the notch 5 is located, with the notch 5 located between the two guide nozzles 9.

[0039] The swing drive unit includes a drive cylinder 10 fixedly connected to the support platform 25. The cylinder base of the drive cylinder 10 is fixed to the cylinder rod of the control cylinder 4. That is, in this embodiment, the drive cylinder 10 is arranged between the support platform 25 and the control cylinder 4, and the cylinder base of the drive cylinder 10 is fixedly connected to both the support platform 25 and the cylinder rod of the control cylinder 4. In this way, the control cylinder 4 can directly drive the drive cylinder 10 to move linearly, and can also directly drive the support platform 25 to move linearly by driving the drive cylinder 10.

[0040] The cylinder rod of the driving cylinder 10 is connected to a swing control member, which simultaneously abuts against the two swing arms 6 near the control cylinder 4. Specifically, in this embodiment, the swing control member is a wheel 11 rotatably connected to the cylinder rod of the driving cylinder 10. Two sets of wheels 11 are symmetrically distributed, each abutting against the two swing arms 6. This reduces the diameter of the wheels 11, making them easier to configure and install. In actual use, a single wheel 11 can also be designed, with this wheel 11 abutting against both swing arms 6.

[0041] In addition, combined Figure 1 and Figure 4 As shown, the tying mechanism in this embodiment also includes a nail rack 12 for storing tying nails 24. The nail rack 12 is fixed on a supporting platform 25. The nail rack 12 has a horizontal portion 13 and a vertical portion 14 that are interconnected and integrally formed. The horizontal portion 13 and the vertical portion 14 have a smooth transition. A nailing position 15 is provided on the supporting platform 25. The vertical portion 14 of the nail rack 12 is located directly above the nailing position 15. The cylinder rod of the driving cylinder 10 is fixedly connected to a push handle 16. The push handle 16 is used to push the tying nail 24 from the nailing position 15 to the notch 5 to push the tying nail 24. The nailing position 15 is located between the notch 5 and the push handle 16 and is located on the moving path of the push handle 16.

[0042] A nail pushing head 17 is also slidably provided on the nail rack 12, and the nail pushing head 17 is used to push the binding nails 24 to move along the nail rack 12. A compression spring is connected between the nail pushing head 17 and the nail rack 12. The nail pushing head 17 generates a continuous thrust on the binding nails 24 through the compression spring, so that the binding nails 24 can be automatically pushed to the binding position 15 one after another.

[0043] In the specific implementation of this embodiment, the lashing nails 24 are arc-shaped and arranged on the nail rack 12. When arranged, the lashing nails 24 on the horizontal portion 13 are opened upward, and the lashing nails 24 on the vertical portion 14 are opened toward the side of the notch 5. The pusher head 17 generates a continuous thrust on the lashing nails 24 through the compression spring, so that the lashing nails 24 can be automatically pushed to the nailing position 15 one after another. The adjacent lashing nails 24 are fixed by local adhesive, so that there is a certain fixing and restraining effect between the adjacent lashing nails 24, so that the lashing nails 24 will not fall freely on the vertical section to the nailing position 15. At the same time, due to the local adhesive effect, the arranged lashing nails 24 can rotate at the connection part of the horizontal portion 13 and the vertical portion 14. The arrangement direction of the tying nails 24 will change at the bend without separation. After the tying nails 24 are installed, the tying nail 24 at the lower end of the vertical portion 14 just breaks away from the vertical portion 14 and falls on the nailing position 15. However, at this time, the tying nail 24 and the tying nail 24 above are still not separated from each other due to the adhesion, that is, the distance between the nailing position 15 and the lower end of the vertical portion 14 is just the thickness of a tying nail 24, so that only one tying nail 24 will fall on the nailing position 15 at a time.

[0044] When the bag opening of the packaging bag needs to be tied and sealed, the lifting cylinder 3 works and flips the tying mechanism from a vertical state to a horizontal state through the mounting plate 2. Then, the control cylinder 4 works and pushes the driving cylinder 10 and the supporting platform 25 forward until the bag opening of the packaging bag enters the notch 5 from the front end of the notch 5. The guide nozzle 9 is used to guide the packaging bag so that the bag opening of the packaging bag can enter the notch 5 completely and smoothly. Then, the driving cylinder 10 works, and the cylinder rod of the driving cylinder 10 drives the wheel 11 and the push handle 16 to move in a straight line. The push handle 16 pushes the binding nail 24 on the nailing position 15 forward, so that the binding nail 24 is separated from the binding nail 24 on the nail rack 12 and moves to the notch 5 to be used for binding. After the tying nail 24 is moved to the notch 5, the cylinder rod of the driving cylinder 10 contracts, driving the push handle 16 and the wheel 11 to move backward, and the wheel 11 pushes the end of the swing arm 6 close to the driving cylinder 10, so that the two swing arms 6 close to the end of the driving cylinder 10 open, and the two swing arms 6 close to the end of the notch 5 swing in the opposite direction and close, thereby closing the two ends of the tying nail 24, so that the tying nail 24 is tied to the bag opening, completing the tying process.

[0045] Then the cylinder rod of the driving cylinder 10 is extended and reset again, the wheel 11 moves toward the stapling position 15, and the end of the swing arm 6 close to the driving cylinder 10 is reset under the action of the tension spring, so that the ends of the two swing arms 6 close to the notch 5 are reset and move away from each other. Then the control cylinder 4 controls the driving cylinder 10 and the supporting platform 25 to reset, so that the bag mouth of the completed packaging bag carrying the tied binding nails 24 are detached from the front end of the notch 5, thereby completing a tying operation.

[0046] Of course it is easy to think of, combined with Figure 4 As shown, when the push handle 16 pushes the tying nail 24 on the nailing position 15 away and transfers it to the notch 5, the push handle 16 and the upper end surface of the cylinder rod of the driving cylinder 10 always abut against the lower end of the nail rack 12. In this way, the push handle 16 and the cylinder rod of the driving cylinder 10 can isolate the lower end of the nail rack 12 from the nailing position 15. At this time, the latter tying nail 24 is blocked by the push handle 16 and the cylinder rod of the driving cylinder 10 and will not fall into the nailing position 15. When one bundling is completed, the cylinder rod and the push handle 16 of the driving cylinder 10 move backward and approach the cylinder seat of the driving cylinder 10. When the push handle 16 moves between the nailing position 15 and the driving cylinder 10, there is no obstruction between the nailing position 15 and the lower end of the nail rack 12. The tying nail 24 at the bottom of the nail rack 12 automatically falls into the nailing position 15 under the push of the nail pushing head 17, thereby completing the automatic nailing of the tying nail 24.

[0047] Repeat the above process and carry out the next tying operation.

[0048] Example 2

[0049] The difference between this embodiment and embodiment 1 is that the structure of the swing control member is different, such as Figure 5 As shown, the swing control component in this embodiment is a wedge block 18 fixedly connected to the cylinder rod of the driving cylinder 10. The diameter of the wedge block 18 at one end facing the notch 5 is larger than that at the other end. Wedge surfaces are provided on both side ends of the wedge block 18 and the wedge surfaces are against the two swing arms 6.

[0050] The process of specific implementation of this embodiment is basically the same as that of Example 1, and the only difference is that the swing control process of the swing arm 6 by the swing control member is different. In this embodiment, when the driving cylinder 10 causes the two swing arms 6 to open close to one end of the driving cylinder 10 through the swing control member, the swing arm 6 is swung by squeezing and pushing the swing arm 6 by the wedge block 18. Compared with pushing the swing arm 6 by the wheel 11, this embodiment uses the wedge block 18 to push the swing arm 6. Since the wedge surface of the swing control member has a larger area for contact with the swing arm 6, this is more conducive to the swing control of the swing arm 6.

[0051] Example 3

[0052] The difference between this embodiment and embodiment 1 and embodiment 2 is that the structure of the swing control member is different. Figure 6 and Figure 7 As shown, the swing control member in this embodiment includes a rack 19 fixedly connected to the cylinder rod of the driving cylinder 10. The rack 19 is arranged parallel to the axial direction of the cylinder rod of the driving cylinder 10. A gear 20 is meshed with the rack 19. The gear 20 is coaxially fixedly connected to a double-ended screw 21. The two ends of the double-ended screw 21 are rotatably connected to the support platform 25 through bearings. In this way, the double-ended screw 21 and the gear 20 are both rotatably matched with the support platform 25. The two ends of the double-ended screw 21 are sleeved and threadedly connected with a sliding sleeve 22. The sliding sleeve 22 is slidably arranged on the support platform 25 along the axial direction of the double-ended screw 21. The sliding sleeve 22 is fixedly connected to the two pushing blocks 23, and the two pushing blocks 23 are respectively abutted against the two swing arms 6. The sliding connection between the sliding sleeve 22 and the support platform 25 can be achieved by providing a slide groove on the support platform 25, and the sliding sleeve 22 is limited and clamped in the slide groove so that the sliding sleeve 22 can only slide along the slide groove and will not rotate with the double-ended screw 21.

[0053] The specific implementation process of this embodiment is basically the same as that of embodiment 1 and embodiment 2, and the only difference is that the swing control part controls the swing of the swing arm 6. The swing control part in this embodiment controls the swing of the swing arm 6 in the following way: when the cylinder rod of the driving cylinder 10 is shortened, the cylinder rod drives the rack 19 to move, and the rack 19 drives the gear 20 to rotate, thereby rotating the double-headed screw 21. Since the threads at both ends of the double-headed screw 21 rotate in opposite directions, the two sliding sleeves 22 slide in opposite directions on the double-headed screw 21 and drive the push block 23 to push the swing arm 6, causing the swing arm 6 to swing. Since the push block 23 does not move along the axial direction of the cylinder rod of the driving cylinder 10 during the process of pushing the swing arm 6, the push block 23 will only contact a small area of the swing arm 6, thereby reducing the area of wear on the swing arm 6 and helping to extend the service life of the swing arm 6.

[0054] The above description is merely an embodiment of the present invention, and the commonly known specific technical solutions and / or features of the solution are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be considered as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection claimed in this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
