[0032] In powder equipment or manufacturing industries, material transportation is very common, and material transportation requires packaging. During packaging, nylon bags, PE bags, ton bags, etc. are generally used for packaging. For example, in powder industries such as fertilizers, cement, flour, and manufacturing, in order to prevent material leakage, the packaging bags need to be fixed and bundled. The existing method is to rely on rubber bands, cable ties, nylon ropes, iron wires, etc. for manual bundling, which is inconvenient to install and remove, and the low reliability of bundling easily causes material leakage and thus pollutes the environment.
[0033] In view of this, the utility model proposes a clamp tooling and production equipment, which improves the degree of automation, improves the reliability of bundling material bags and discharge pipes during powder packaging, and avoids the pollution of materials to human body and environment. Figures 1 to 5 The utility model provides an embodiment of a fixture and production equipment.
[0034] Please refer to Figure 1 , Figure 1 The schematic diagram of the structure of the clamping tool 100 provided by the utility model is used to clamp and position the receiving bag 8 of the discharge pipe 5 set on the production equipment 1000. The clamping tool 100 includes a plurality of clamping members 1. The clamping member 1 can be a whole or two parts arranged at intervals. As long as the clamping member 1 is elastically facing the first side of the discharge pipe 5, the first side is used to directly act on the receiving bag of the discharge pipe of the production equipment to elastically suppress it.
[0035] It should be noted that the first side portion of the clamping member is elastically arranged or the entire clamping member is elastically arranged, and the plurality of clamping members 1 clamp the outer wall of the receiving bag 8 sleeved on the discharge pipe 5 to jointly form a clamping space;
[0036] The specific form of the driving member 2 is not limited here, and it can be pneumatic drive, hydraulic drive or electric drive, etc. The driving member 2 drives the clamping member 1 to move toward the direction of the discharge pipe. All of the multiple clamping members 1 can move toward the direction of the discharge pipe, or a part of the multiple clamping members 1 can move toward the direction of the discharge pipe, while the other part is fixed. No specific limitation is made here.
[0037] In the technical solution of the utility model, the driving member 2 drives the clamping member 1 to change the clamping space. When the clamping space changes from small to large, the clamping member elastically presses the receiving bag 8 of the discharge pipe 5 arranged on the production equipment 1000. When the clamping space changes from large to small, the clamping member releases the elastic pressing. This not only improves the degree of automation, but also improves the reliability of the bundling of the material bag and the discharge port during the powder packaging process, while avoiding the pollution of the human body and the environment by the leakage of materials.
[0038] The structure of the clamping member 1 is described in detail below by taking the elastic structure as a whole being elastic as an example. Figure 2 The clamping member includes a main body 11 and an elastic structure 12 arranged on a first side of the main body 11. The specific form of the main body 11 is not limited, and it can be an annular steel ring or a square steel ring. It can be set to maintain rigidity according to the diameter of the discharge pipe. In this embodiment, the main body 11 is a semi-annular steel ring to match the diameter of the material pipe wall. The elastic structure 12 is elastically arranged as a whole, so that the clamping space of the elastic structure 12 is larger after elastic deformation, and the clamping is more secure. A part of the elastic structure 12 is spaced or arranged between the main body 11. The elastic structure 12 as a whole is spaced apart from the steel ring. Specifically, the middle part or the whole of the elastic structure 12 is spaced apart from the steel ring. In this way, the steel ring can provide support and safety protection for the elastic structure 12 when the first side of the elastic structure elastically presses the outer wall of the receiving bag 8 sleeved on the discharge pipe 5, while ensuring the clamping effect, so as to avoid damage to the elastic structure 12, thereby damaging the receiving bag 8 and the discharge pipe 5 and causing material leakage. In addition, it can ensure that the elastic structure 12 returns to its original state after each elastic pressing is completed.
[0039] In order to improve the reliability of the clamping member 1, please refer to Figure 2 and Figure 4The elastic structure 12 includes two clip ears 121 arranged at both ends of the steel ring along the length direction and a belt body 122 connecting the two clip ears 121. The clip ears 121 can be made of nylon or rubber, and the belt body 122 can be a nylon rope, a rubber band or an elastic cloth belt. In this embodiment, the two clip ears 121 are made of rubber blocks, and the belt body 122 is an elastic cloth belt, so that the contact area with the receiving bag is larger and the bundling is more secure. In particular, the rubber block is connected to the two ends of the elastic cloth belt after hot melting, the process is simple and the fixing effect is better. The clip ears 121 are arranged along the length direction of the steel ring to prevent the elastic cloth belt from breaking and causing the two steel rings to collide; the two ends of the elastic cloth belt are respectively connected to the two clip ears 121, in particular, the rubber block is connected to the elastic cloth belt and the two ends of the steel ring after hot melting, the process is simple and the fixing effect is better. Specifically, when the driving member 2 drives the steel ring to move in the direction of the discharge pipe 5, the clamping space of the elastic cloth belt becomes larger to elastically press the outer wall of the receiving bag 8 sleeved on the discharge pipe 5, so that the connection between the receiving bag 8 and the discharge pipe 5 is tightened more firmly. In this embodiment, the elastic cloth belt and the steel ring are arranged at intervals as a whole, which can buffer the torque during the driving process, reduce the friction at the connection between the receiving bag 8 and the discharge pipe 5, and is convenient for the receiving bag 8 of the discharge pipe with different diameters, which can enhance the sealing between the receiving bag 8 and the discharge pipe 5 and enhance the service life of various related equipment.
[0040] Based on the above embodiments, in order to improve the matching degree of the plurality of clamping members, further, please continue to refer to Figure 2 One of each two adjacent clamping ears 121 is provided with a groove 121a, and the other is formed with a convex rib 121b, so that when the clamping fixture 100 clamps the discharge pipe 5, as the multiple clamping members 1 are closed, the convex ribs 121b of the two adjacent clamping ears 121 extend into the groove 121a to form a fit, which can not only increase the friction between the clamping ears 121, but also form a positioning between the two adjacent clamping ears 121, making the clamping fit between the adjacent clamping members 1 more reliable.
[0041] In order to enable the plurality of clamping members 1 to move and improve the clamping efficiency, further, please refer to Figure 1 In this embodiment, the driving member 2 is provided with a plurality of corresponding clamping members 1, and the driving member 2 includes a cylinder 21, and the cylinder 21 includes a piston rod 22. The piston rod 22 of the cylinder 21 drives the connection of the steel ring away from the center of the outer wall of the first side to reduce the torque and form a fixed stroke. The driving connection can be a fixed connection or a hinged connection; when the steel ring moves toward the discharge pipe 5, the piston rod 22 extends, and when the steel ring moves away from the discharge pipe 5, the piston rod 22 shortens. The pneumatic drive is provided in the form of compressed air as the flow medium, which has low cost and high reliability.
[0042] In order to enable the multiple steel rings to move synchronously, in this embodiment, the multiple driving members 2 are simultaneously connected to the same controller to enable synchronous driving. The specific form of the controller is not limited here, for example, it can be a single-chip microcomputer controller or a PLC controller, which is not explained in detail here.
[0043] In particular, see Figure 1 The clamping member and the corresponding driving member 2 constitute a clamping assembly. The clamping assembly is provided with two groups. The clamping assembly is symmetrically arranged on both sides of the discharge pipe 5 of the production equipment 1000, so that the force on the discharge pipe 5 is more balanced.
[0044] For further information, see Figure 3 The clamp tooling 100 also includes a connecting piece 3, one end of the connecting piece 3 is used for rotationally mounting to the frame, and the other end is rotationally connected to the two ends of the steel ring, so that the connecting piece 3 can drive the steel ring to swing back and forth around the connecting piece 3 and has a guiding effect on the stroke of the steel ring. In addition, the setting of the connecting piece 3 makes the strength of the entire clamp higher; the piston rod 22 of the cylinder 21 is rotationally connected to the steel ring through a rotating shaft. Such a connection method enables the steel ring to remain level with the ground when it is loosened or clamped, reducing the swing of the steel ring, thereby improving the reliability of clamping.
[0045] Based on the above examples, please refer to Figure 1 The utility model also proposes a production equipment 1000, including a machine base 4 and a clamping tool 100, the machine base 4 is provided with a discharge pipe 5, the clamping tool 100 is used to clamp and position the receiving bag 8 of the discharge pipe 5 of the production equipment 1000, the driving member 2 drives the clamping member 1 to change the clamping space, when the clamping space changes from small to large, the clamping member 1 elastically presses the receiving bag 8 of the discharge pipe 5 of the production equipment 1000, and when the clamping space changes from large to small, the clamping member releases the elastic pressing, which not only improves the degree of automation, but also improves the reliability of the bundling of the material bag and the discharge port during the powder packaging process, while avoiding the pollution of the human body and the environment by the leakage of materials.
[0046] In order to ensure the continuous and timely discharge of materials during the material conveying process and to ensure the air tightness of the discharge pipe, please refer to Figure 1 In the embodiment, the upper end of the discharge pipe 5 is also connected to a wind lock 6, which is composed of an impeller, a casing, an end cover and a bearing (not shown in the figure). During the continuous rotation of the impeller, the material is discharged from the bottom to ensure the continuity of the feeding. The lower end of the wind lock is connected to the discharge pipe through a flange, which can be easily disassembled repeatedly. The specific model of the wind lock 6 is not limited here.
[0047] Based on the above embodiment, the clamp tooling 100 is currently used in the artificial graphite negative electrode packaging industry. The packaging of materials in this industry is all packaged and transported in ton bags. The industry has high requirements for fiber foreign matter, so rubber bands are generally used for bundling, which is very inconvenient to install and remove. If you encounter a hard material such as aluminum plastic film, it is even more difficult to bundle. Therefore, please refer to Figure 5 The outer wall of the discharge pipe 5 is provided with a convex strip 7, and the convex strip 7 is located below the clamping member 1. Specifically, the material receiving bag 8 is sleeved on the convex strip 7, and the clamp tooling 100 is clamped at the upper end of the connection between the material receiving bag 8 and the convex strip 7. In this way, the convex strip 7 provides a limiting protection for the clamp tooling 100, preventing the clamp tooling 100 from sliding down and falling out of the discharge pipe 5, causing leakage of materials and polluting the environment.
[0048] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
