Description

Technical Field

[0001] This utility model belongs to the field of pyrotechnics technology, specifically relating to a clamp that facilitates the gripping of raw material barrels. Background Technology

[0002] Raw materials for pyrotechnics are the basic substances used to manufacture various pyrotechnics (such as detonators, explosives, and fuses), and their properties directly determine the function and safety of the pyrotechnics. As a key link in the production of raw materials for pyrotechnics, repackaging is the core link connecting the supply of raw materials with subsequent processing, and has a decisive impact on production safety and product quality.

[0003] Currently, the packaging of raw materials for pyrotechnic products is mostly done manually. The process involves opening the raw material drum, removing the moisture-proof bags and inner packaging bags, and then manually packaging the materials to convert bulk raw materials into small-dose units suitable for subsequent production. However, manual packaging has many drawbacks, such as high safety risks, low sorting accuracy, and limited operating speed, making it difficult to meet the needs of large-scale production. To solve these problems and achieve automated packaging, the opened raw material drums need to be moved from their initial position to an automated packaging mechanism. However, the following problems arise during the movement of the raw material drums: 1. The moisture-proof bags and inner packaging bags inside the raw material barrel cannot be secured after being turned out. Therefore, they are prone to interfering with other structures during the movement by the robotic arm, causing the raw material barrel to tilt and creating a hazard.

[0004] 2. The raw material drums are packaged in paper drums. Due to the unstable structure of the paper drums, there is a risk that the raw material drums may fall off during the process of being grasped and moved by the robotic arm. Utility Model Content

[0005] The purpose of this invention is to solve the aforementioned problems by providing a clamp that facilitates the gripping of raw material drums. This clamp can secure the moisture-proof bag and inner packaging bag that have been turned out of the drum, and also increases the stability of the raw material drum during movement. When the robotic arm grips the raw material drum, it grips the fixed wall on the outside of the drum. At the same time, the support plate below the fixed wall also supports the bottom of the drum, effectively preventing the drum from falling off during movement.

[0006] To achieve the above objectives, this utility model provides a clamp for easy gripping of raw material barrels, including a fixed wall that surrounds the raw material barrel. One side of the fixed wall is provided with a locking structure, which can loosen or lock the fixed wall relative to the raw material barrel. The other side of the fixed wall is connected to one end of a connecting rod, and the other end of the connecting rod is provided with a support plate for supporting the raw material barrel and reducing the stress on the fixed wall.

[0007] Advantages and beneficial effects of this utility model

[0008] 1. This utility model has two fixed walls in the circumferential direction of the raw material barrel. The two fixed walls can be locked or released relative to the raw material barrel through a locking structure on one side. When released, the two fixed walls can be opened and the support plate at the bottom of the clamp can be pushed into the bottom of the raw material barrel, or the clamp can be separated from the raw material barrel. When locked, the moisture-proof bag, inner packaging bag and raw material barrel can be fixed by the two fixed walls. Therefore, there will be no interference with other structures during the movement of the raw material barrel by the robot arm, thus solving the problem of the raw material barrel tilting and avoiding the occurrence of danger.

[0009] 2. The fixed wall in this utility model not only serves to secure the moisture-proof bag and the inner packaging bag, but also avoids direct contact between the robotic arm and the raw material barrel. When the robotic arm grabs the raw material barrel, it will grip the fixed wall. At the same time, one side of the fixed wall is connected to the pallet via a connecting rod, and the pallet is located at the bottom of the raw material barrel. As the raw material barrel moves with the robotic arm, the pallet will support the raw material barrel, thereby effectively preventing the raw material barrel from falling off during the movement.

[0010] 3. The clamp in this utility model has a simple, lightweight structure that is easy to operate. It can make the raw material bucket move stably during the clamping process and avoid direct contact between the pyrotechnic materials and people. Attached Figure Description

[0016] like Figure 1 As shown, a clamp for easy gripping of raw material drums includes a fixed wall 2 that surrounds the outer wall of the raw material drum 1. The fixed wall 2 can fix the outwardly turned moisture-proof bag and inner packaging bag, and also prevent the robotic arm from directly contacting the raw material drum 1 when gripping, avoiding the risk of falling off due to the instability of the paper drum structure. A locking structure 3 is provided on one side of the fixed wall 2. The locking structure 3 can loosen or lock the fixed wall 2 relative to the raw material drum 1. When unlocked, the support plate 5 on the clamp can be pushed into the bottom of the raw material drum 1 or the clamp can be separated from the raw material drum 1. When the fixed wall 2 is locked relative to the raw material drum 1 by the locking structure 3, the moisture-proof bag, inner packaging bag and raw material drum 1 that have turned out of the drum can be fixed, preventing the outwardly turned moisture-proof bag and inner packaging bag from interfering with other structures when the robotic arm moves the raw material drum 1. Therefore, the problem of the raw material drum tilting is solved, and the danger caused by the tilting of the raw material drum is avoided. The other side of the fixed wall 2 is connected to the upper end of the connecting rod 4. The lower end of the connecting rod 4 is provided with a support plate 5. The support plate 5 can make the clamp set vertically, and also supports the raw material barrel 1 and reduces the force on the fixed wall 2.

[0017] Considering that the raw material drums containing pyrotechnic materials are very heavy, weighing up to 75 kg, the fixing wall 2 in this embodiment uses an opening and closing mechanism to loosen or lock the moisture-proof bag and inner packaging bag that have been turned out of the raw material drum. See below. Figures 2 to 4 The fixed wall 2 will be described in further detail.

[0018] The fixed wall 2 is divided into a first fixed wall 21 and a second fixed wall 22. The structure of the first fixed wall 21 is the same as that of the second fixed wall 22. A locking structure 3 is provided on one side adjacent to the first fixed wall 21 and the second fixed wall 22. The other side adjacent to the first fixed wall 21 and the second fixed wall 22 is rotatably connected by a hinge 6. When the locking structure 3 is unlocked, the first fixed wall 21 and the second fixed wall 22 can be rotated outward relative to each other around the hinge 6, so that the fixed wall 2 is in the open state. At this time, it is convenient to push the tray 5 on the clamp into the bottom of the raw material barrel 1 or to separate the clamp from the raw material barrel 1. Then, the first fixed wall 21 and the second fixed wall 22 are rotated inward relative to each other through the hinge 6, so that the fixed wall 2 is in the closed state. Then, the first fixed wall 21 and the second fixed wall 22 are locked by the locking structure 3, thereby fixing the turned-out moisture-proof bag, the inner packaging bag and the raw material barrel 1.

[0019] like Figure 2 and Figure 3 As shown, the locking structure 3 is a long-arm type hook and loop fastener, which is an existing structure with the model number PKWSAI. The locking seat 31 of the hook and loop fastener is connected to the first fixed wall 21, and the base 32 of the hook and loop fastener is connected to the second fixed wall 22. The base 32 is provided with a rotatable long-arm handle 33. By manually moving the long-arm handle 33, the locking buckle 34 at its front end can be locked or separated from the locking seat 31.

[0020] like Figure 4 As shown, a connecting rod 4 is welded to the fixed wall 2 on one side of the hinge 6. The connecting rod 4 is used to support the fixed wall 2 and to connect the pallet 5. The pallet 5 has a downward sloping ramp on the side away from the connecting rod 4. When the clamp is moved toward the raw material barrel 1, the ramp on the pallet 5 makes it easy to push the pallet 5 into the bottom of the raw material barrel 1. When the robot arm clamps and moves the raw material barrel 1, the pallet 5 can support the raw material barrel 1, thereby further preventing the raw material barrel 1 from falling off during the movement.

[0021] like Figure 3 As shown, the first fixed wall 21 and the second fixed wall 22 have the same structure, both including a body 23. The body 23 has a plurality of horizontally arranged elongated through holes 24 evenly distributed on it. The through holes 24 can reduce the weight of the first fixed wall 21 and the second fixed wall 22, making the clamp lighter. The upper and lower sides of the body 23 are provided with reinforcing walls 25. The middle part of the reinforcing wall 25 has an outwardly protruding ridge 26. Through the design of the reinforcing wall 25 and the ridge 26, the structure of the first fixed wall 21 and the second fixed wall 22 can be made more robust and less prone to deformation during clamping, thus increasing the stability of the fixed wall 2.

[0022] Work process First, open the top cover of raw material drum 1, turn the moisture-proof bag and inner packaging bag inside out, then unlock the buckle, rotate the first fixing wall 21 and the second fixing wall 22 outward around the hinge 6, thereby opening the fixing wall 2, push the tray 5 on the clamp into the bottom of the raw material drum 1 via the ramp, then close the first fixing wall 21 and the second fixing wall 22, bringing them close to the outer wall of the raw material drum 1, and then lock the first fixing wall 21 and the second fixing wall 22 with the buckle 3, thereby locking and securing the turned-out moisture-proof bag, inner packaging bag and raw material drum 1. This application has been applied in a large military factory in China, greatly improving production efficiency.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, and are not intended to limit them. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the present utility model.
