Abstract
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. In order to solve this problem, the bag opening is now sealed by wire tying. However, the current method of closing the packaging bag by clamping the plywood is obviously unable to meet the needs of wire tying and sealing. Therefore, it is necessary to improve the existing packaging bag closing device to meet the needs of sealing the bag opening by wire tying. Utility Model Content
[0004] The utility model aims to provide an automatic closing device for anode powder packaging, so as to realize the closing processing of packaging bags and meet the processing requirements of bag openings tied with iron wires.
[0005] 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 feeding pipe, a front and rear closing mechanism and a left and right closing mechanism are provided on the frame, the left and right closing mechanisms comprise a left closing unit and a right closing unit symmetrically distributed on the left and right sides of the feeding pipe, the left closing unit comprises a swinging cylinder rotatably connected to the frame and a swinging claw rotatably connected to the outer wall of the feeding pipe, the cylinder rod of the swinging cylinder is rotatably connected to the swinging claw; the front and rear closing mechanisms comprise a front closing unit and a rear closing unit, one of the front closing unit and the rear closing unit is located on the swinging claw of the left closing unit, and the other is located on the swinging claw of the right closing unit; the front closing unit and the rear closing unit both comprise a translation driving member, the translation driving member is arranged on the swinging claw, the translation driving member is fixedly connected to the translation claw, the translation driving member is used to drive the translation claw to move in translation, and the translation driving member in the front closing unit and the translation driving member in the rear closing unit are both horizontally arranged.
[0006] The principle and advantages of this solution are: in this solution, the swing cylinder is used to drive the swinging jaws to swing, so that when the two swinging jaws swing from the side of the discharge tube to the bottom, they can close and squeeze the bag opening in the left and right directions, and the translation drive is used to drive the translation jaws to move, so that the two translation jaws can move toward each other and squeeze the bag opening in the front and back directions, thereby achieving the purpose of closing the bag opening in four directions. Compared with the traditional splint closing method, after closing, the side walls of the bag opening are staggered and gathered together, so that the bag opening has only a smaller width, which can make it more convenient to tie the bag opening with binding nails, and thus better adapt to the processing needs of tying the bag opening with binding nails, and it is less likely to leak after tying with binding nails, thereby improving the packaging effect.
[0007] Preferably, as an improvement, the swing clamp includes a base and two layers of splints fixedly connected to the base, the two layers of splints are distributed parallel to each other, and there is a gap between the two layers of splints to form a sealing cavity that is bidirectionally through the front and back.
[0008] Through the above scheme, the two layers of plywood are used to squeeze and close the bag opening of the packaging bag at the upper and lower parts respectively, thereby improving the closing effect and closing quality; at the same time, after the two layers of plywood clamp the bag opening, they can form upward and downward traction on the bag opening, making it more convenient to bundle and seal the bag opening by the sealing mouth.
[0009] Preferably, as an improvement, the splints are detachably fixedly connected to the base.
[0010] Through the above solution, the splint and the base are detachably fixedly connected, so that the splint can be easily disassembled, assembled and maintained while ensuring the clamping and closing effect of the splint on the packaging bag.
[0011] Preferably, as an improvement, a vertically extending adjustment hole is provided on the side edge of the base, and the clamping plates are detachably fixedly connected to the adjustment hole.
[0012] Through the above scheme, the splint is detachably fixedly connected to the base through the adjustment hole, so that the splint can be fixed at different positions of the adjustment hole, thereby changing the height of the splint when fixed on the base, thereby achieving the purpose of adjusting the distance between the two splints. In this way, the positions of the two splints for clamping, fixing and pulling on the bag opening of the packaging bag are adjustable, which is more practical.
[0013] Preferably, as an improvement, the translation clamping jaw is C-shaped.
[0014] Through the above scheme, the C-shaped translation clamp can form a front-to-back squeeze closing on the upper and lower parts of the bag opening, thereby cooperating with the swinging clamp to improve the closing effect and closing quality of the bag opening.
[0015] Preferably, as an improvement, the translational clamping jaw and the translational driving member are both located between the two layers of clamping plates, and the translational driving member can drive the translational clamping jaw to enter and exit the sealing cavity.
[0016] Through the above scheme, the translational clamp and the translational driving member are arranged between the two layers of plywood, so that when the translational driving member drives the translational clamp to move horizontally, the translational clamp can enter and exit the sealing cavity, and when the two translational clamps move relative to each other, the distance between the two translational clamps can also become smaller or even offset each other, so that when the bag opening is closed, the width of the bag opening can be further reduced, which is more convenient for wire bundling and improves the closing effect and quality of the bag.
[0017] Preferably, as an improvement, the swinging jaw and the translational jaw are both hollow.
[0018] Through the above solution, the hollow swinging jaw and the translational jaw are lighter, easier to drive and save power.
[0019] Preferably, as an improvement, the translation drive member includes a screw, a sleeve and a drive motor, both ends of the screw are rotatably connected to the swing clamp, the drive motor is connected to the screw and is used to drive the screw to rotate, the sleeve is sleeved on the screw and cooperates with the screw thread, the sleeve is fixedly connected to the translation clamp, and the sleeve is laterally slidably connected to the swing clamp.
[0020] Through the above scheme, the rotation of the lead screw causes the sleeve to slide on the lead screw, thereby causing the sleeve to drive the translation clamp to move. The lead screw has a guiding effect on the movement of the sleeve and the translation clamp, so that the translation clamp can move horizontally in a predetermined direction with higher movement accuracy.
[0021] Preferably, as an improvement, the translation drive member is a translation cylinder, the translation cylinder is fixed on the swing clamp, and the cylinder rod of the translation cylinder is fixedly connected to the translation clamp.
[0022] Through the above solution, the translational clamping jaw is directly driven to move by the cylinder, which has the advantages of fast response speed, simple structure, and easy maintenance and control. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] 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.
[0027] The figure marks in the drawings of the specification include: frame 1, feeding pipe 2, left closing unit 3, right closing unit 4, swing cylinder 5, swing clamp 6, base 7, clamping plate 8, adjustment hole 9, front closing unit 10, rear closing unit 11, screw 12, sliding sleeve 13, sealing cavity 14, and translation clamp 15.
[0028] Example 1
[0029] The structure of the automatic closing device for anode powder packaging in this embodiment is as follows: Figure 1 、 2 3, including a frame 1, the frame 1 is provided with a feed pipe 2, a front and rear closing mechanism and a left and right closing mechanism, wherein:
[0030] The left and right closing mechanism includes a left closing unit 3 and a right closing unit 4 symmetrically distributed on the left and right sides of the feeding tube 2. The left closing unit 3 includes a swing cylinder 5 rotatably connected to the frame 1 via a rotating shaft and a swing clamp 6 rotatably connected to the outer wall of the feeding tube 2 via a rotating shaft. The cylinder rod of the swing cylinder 5 is rotatably connected to the swing clamp 6 via a rotating shaft. In this way, while the swing cylinder 5 drives the swing clamp 6 to swing, the swing clamp 6 can rotate relative to the swing cylinder 5, so that the swing cylinder 5 adapts to the position of the swing clamp 6 without blocking the swing clamp 6. Figure 2 and 3 As shown together, the swing clamp 6 includes a base 7 and two layers of plywood 8 fixedly connected to the base 7, the two layers of plywood 8 are distributed parallel to each other on the upper and lower sides, and there is a gap between the two layers of plywood 8 to form a sealing cavity 14 that is bidirectionally through the front and back sides. Specifically, in this embodiment, the fixed connection between the plywood 8 and the base 7 is detachably fixed by bolts, and its implementation method is as follows: a vertically extending adjustment hole 9 is provided on the side edge of the base 7, and the side ends of the plywood 8 are detachably fixed in the adjustment hole 9 by bolts, so that the fixed position of the plywood 8 in the adjustment hole 9 is adjustable.
[0031] The front and rear closing mechanism includes a front closing unit 10 and a rear closing unit 11. One of the front closing unit 10 and the rear closing unit 11 is located on the swinging clamp 6 of the left closing unit 3, and the other is located on the swinging clamp 6 of the right closing unit 4. The front closing unit 10 and the rear closing unit 11 both include a translation drive member, which is arranged on the swinging clamp 6 and is fixedly connected to a translation clamp 15. The translation drive member is used to drive the translation clamp 15 to translate. The translation drive member in the front closing unit 10 and the translation drive member in the rear closing unit 11 are both arranged horizontally; specifically, as shown in FIG. Figure 3 As shown, the translation drive member in this embodiment includes a lead screw 12, a sleeve 13 and a drive motor. The two ends of the lead screw 12 are rotatably connected to the base 7 of the swing clamp 6 through bearings. The drive motor is connected to the lead screw 12 and is used to drive the lead screw 12 to rotate. The sleeve 13 is sleeved and threadedly connected to the lead screw 12. The sleeve 13 and the translation clamp 15 are fixedly connected by bolts, and the sleeve 13 is laterally slidably connected to the base 7 or the clamping plate 8 of the swing clamp 6. The sliding connection can be specifically adopted in the following manner: a sliding groove is provided on the base 7 or the clamping plate 8, and the sliding sleeve 13 is limited and clamped in the sliding groove. In this way, the sliding sleeve 13 can be limited so that when the lead screw 12 rotates, the sliding sleeve 13 can only slide laterally back and forth on the swing clamp 6 along the axial direction of the lead screw 12, and will not rotate with the lead screw 12. At the same time, the translation clamp 15 in this embodiment is C-shaped. The translational jaws 15 and the translational driving member are both located between the two layers of plywood 8, and the translational driving member can drive the translational jaws 15 in and out of the sealing cavity 14, so that the two translational jaws 15 can be as close as possible or even against each other when moving together, so as to enhance the closing effect of the bag opening.
[0032] In addition, the swinging jaw 6 and the translational jaw 15 in this embodiment are both hollow.
[0033] During actual application, when loading is required, the bag opening of the packaging bag is placed at the discharge pipe 2 for loading.
[0034] After loading, the bag opening needs to be sealed. Before sealing, the bag opening is first closed by this device. When closing, the swing cylinder 5 drives the swing jaws 6 to swing. The two swing jaws 6 swing downward from the side of the discharge pipe 2 and move closer together, thereby squeezing and closing the bag opening from the left and right sides. Then the drive motor drives the screw 12 to rotate. The screw 12 pushes the sliding sleeve 13 to move horizontally and causes the translation jaws 15 to translate horizontally. The two translation jaws 15 move toward each other, approach, and abut against each other, thereby squeezing and closing the bag opening in two directions in the front and back directions. At this time, the bag opening is squeezed and closed from the front, back, left, and right directions, thereby changing from an open state to a closed state, completing the closing operation of the bag opening. The two layers of plywood 8 and the C-shaped translation jaws 15 jointly clamp and pull the upper and lower parts of the bag opening. The binding wire can enter the sealing cavity 14 from the front or rear end of the sealing cavity 14 to bind the middle part of the bag opening.
[0035] When the distance between the two clamping plates 8 needs to be adjusted, the clamping plates 8 only need to be removed from the adjusting holes 9 and then re-fixed at different positions of the adjusting holes 9 .
[0036] Example 2
[0037] The difference between this embodiment and embodiment 1 is that the structure of the translation drive member is different. The translation drive member in this embodiment is a translation cylinder, which is fixed on the swing clamp 6, and the cylinder rod of the translation cylinder is fixedly connected to the translation clamp 15.
[0038] When this embodiment is implemented, the difference from the implementation process of embodiment 1 is only the closing process of the bag opening in the front-to-back direction. When this embodiment closes the bag opening in the front-to-back direction, the translation cylinder works and drives the translation clamp 15 to move horizontally, and the two translation clamps 15 move closer and abut against each other, thereby performing bidirectional squeezing and closing of the bag opening in the front-to-back direction.
[0039] The above is only an embodiment of the present invention. The front, back, left and right in this content are only used to name four different directions of the same plane, and the common sense such as the specific technical solutions and / or characteristics known in the solution are not described in detail here. It should be pointed out 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 regarded 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 required by 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.
