Description

Technical Field

[0001] The present invention relates to the technical field of powder or granular materials, in particular to a ton bag clamping component and a material device. Background Art

[0002] Powdered or granular materials, especially those with high fluidity, such as lithium iron phosphate powder or granules, are often packaged in ton bags during production, turnover, inspection, and logistics. Once filled with these materials, ton bags typically weigh between 300 and 600 kg, which is quite heavy. Due to their high fluidity and difficulty in shaping, these bags require significant manpower for turnover, inspection, and logistics. If the ton bags cannot be kept relatively square during transportation, bulk transport becomes impossible. Furthermore, when using existing mechanically assisted grippers to move the bags, they either fail to lift due to insufficient force, or are punctured due to excessive force, or become irregularly shaped after being moved, rendering them unusable. Consequently, existing techniques often employ the method of attaching hanging ears to the bags, manually hanging the hanging ears before moving them. This method is inefficient and also suffers from the technical drawback of bag deformation. In summary, there are still insurmountable technical obstacles and defects in the production, turnover, inspection and logistics transportation of ton bags of high-fluidity powder materials, resulting in low work efficiency and difficulty in shaping ton bags.

[0003] In view of this, it is necessary to develop a ton bag clamping component and material device to overcome the above-mentioned defects. Summary of the Invention

[0029] (3) Since the distance between the end of the first curved plate and the end of the second curved plate is smaller than the distance between the first clamping plate and the second clamping plate, during the clamping process, even if the bottom of the ton bag is changed in shape, it will not fall from between the end of the first curved plate and the end of the second curved plate. The first curved plate and the second curved plate form an effective support for the bottom of the ton bag and will not puncture the ton bag. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Example 1

[0041] Ginseng Figures 1 to 6 As shown, this embodiment discloses a specific implementation of a ton bag clamping assembly (hereinafter referred to as "clamping assembly").

[0042] Ton bag clamping components, reference Figures 1 to 6As shown, it includes a first clamping assembly 1 and a second clamping assembly 2; the first clamping assembly 1 includes a first clamping plate 11 and a first curved plate 12 arranged at the bottom of the first clamping plate, and a first baffle 13 is provided at the end of the first curved plate 12; the second clamping assembly 2 includes a second clamping plate 21 and a second curved plate 22 arranged at the bottom of the second clamping plate 21, and a second baffle 23 is provided at the end of the second curved plate 22; the first curved plate 12 and the second curved plate 22 constitute the bottom lifting assembly of the ton bag; a first rotating rod 3 and a second rotating rod 4 are respectively provided on both sides of the first curved plate 12 and the second curved plate 22.

[0043] Specifically, see the diagram of ton bags Figure 6 As shown, ton bags filled with powder or granular materials typically weigh 300-600kg. This heavy weight presents drawbacks and obstacles such as difficulty in lifting, easy deformation, and puncture during lifting. Therefore, to achieve a tight grip on the ton bag without puncturing it or causing significant deformation, this places high demands on the clamping of ton bags filled with highly fluid powders. This is achieved through the combined efforts of the following aspects.

[0044] First, see Figure 2 The first clamping plate 11 and the second clamping plate 21 constitute the clamping components on both sides of the ton bag. Since the first clamping plate 11 and the second clamping plate 21 are both in a vertical state, they clamp the two sides of the ton bag through a plane. In order to achieve weight reduction, the first clamping plate 11 and the second clamping plate 21 are provided with several hollow parts.

[0045] Second, see Figure 1 and Figure 2 The first curved plate 12 and the second curved plate 22 form a bottom lifting component for the ton bag, which lifts the bottom of the ton bag through the curved surface. Since the distance between the end of the first curved plate 12 and the end of the second curved plate 22 is smaller than the distance between the first clamping plate 11 and the second clamping plate 21, during the clamping process, even if the bottom of the ton bag is changed in shape, it will not fall from between the end of the first curved plate 12 and the end of the second curved plate 22. The first curved plate 12 and the second curved plate 22 form an effective support for the bottom of the ton bag and will not puncture the ton bag. It should be further explained that the ends of the first curved plate 12 and the second curved plate 22 are respectively provided with a first stop bar 13 and a second stop bar 23; the angle between the first stop bar 13 and the first curved plate 12 is a right angle (see Figure 1 Angle a), the end surface of the first baffle 13 is in contact with the surface of the first curved plate 12, that is, the first baffle 13 and the first curved plate 11 cooperate to form a support for the bottom of the ton bag, and the first baffle 13 can effectively prevent the ton bag from sliding down; the angle between the second baffle 23 and the second curved plate 22 is a right angle (see Figure 1Angle b), the end surface of the second baffle 23 is in contact with the surface of the second curved plate 22, that is, the second baffle 23 and the second curved plate 21 cooperate to support the bottom of the ton bag, and the second baffle 23 can effectively prevent the ton bag from sliding down.

[0046] In addition, in order to further achieve the clamping of the ton bag, a third baffle 14 is set at the connection between the first clamping plate 11 and the first curved plate 12, and a fourth baffle 24 is set at the connection between the second clamping plate 21 and the second curved plate 22. The third baffle 14 and the fourth baffle 24 further achieve the blocking of both sides of the ton bag, especially the two sides near the bottom, to achieve tight clamping; in order to prevent the edges of the baffles from puncturing the ton bag, the cross-sections of the first baffle 13, the second baffle 23, the third baffle 14 and the fourth baffle 24 are all rounded rectangles, that is, the edges of the baffles are rounded, which can not only block the ton bag but also prevent it from puncturing the ton bag.

[0047] Thirdly, see Figure 1 and Figure 2 The first rotating rod 3 and the second rotating rod 4 form a blocking component for the front and rear end surfaces of the ton bag, and the blocking is performed through the cylindrical surface.

[0048] In summary, the clamping components on both sides, the bottom lifting components and the blocking components on the front and rear end surfaces exert force at the same time, that is, the ton bag is clamped through the plane, arc surface and cylinder. There is no part that punctures the ton bag during clamping. When stable clamping and lifting can be achieved, the ton bag will not be punctured, which provides a basis for the automated movement of ton bags in turnover, inspection and logistics transportation.

[0049] Example 2

[0050] See also Figures 1 to 6Based on Example 1, the ton bag clamping assembly further includes a lifting assembly 5, which includes a lifting rail 51 and a lifting platform 52. The first clamping plate 11 and the second clamping plate 21 are respectively mounted on the lifting platform 52 via a first moving assembly 6 and a second moving assembly 7. The lifting platform 52 includes a first guide rail groove 521 and a second guide rail groove 522. The first moving assembly 6 includes a first drive cylinder 61 and a first guide rail 62. The first guide rail 62 cooperates with the first guide rail groove 521. The first guide rail 62 ends at the top of the first clamping plate 11. The first drive cylinder 61 drives the first guide rail 62 to move along the first guide rail groove 521, thereby moving the first clamping plate 11. The second moving assembly 7 includes a second drive cylinder 71 and a second guide rail 72. The second guide rail 72 cooperates with the second guide rail groove 522. The second guide rail 72 ends at the top of the second clamping plate 21. The second drive cylinder 71 drives the second guide rail 72 to move along the second guide rail groove 522, thereby moving the second clamping plate 21.

[0051] Specifically, see Figures 1 to 5 The first drive cylinder 61 and the second drive cylinder 71 are preferably electric cylinders. On the one hand, electric cylinders have high control accuracy, and on the other hand, electric cylinders do not produce oil pollution. The first drive cylinder 61 independently drives the first clamping plate 11 to move left and right along the first guide groove 521, while the second drive cylinder 71 independently drives the second clamping plate 21 to move left and right along the second guide groove 522. The process of clamping a ton bag is as follows: Step 1: The ton bag is placed under the lifting platform 52, and the first drive cylinder 61 and the second drive cylinder 71 respectively drive the first clamping plate 11 and the second clamping plate 21 to open to both sides; Step 2: The lifting platform 52 descends along the lifting track 51, causing the first clamping plate 11 and the second clamping plate 21 to descend, and stops descending when the ends of the first curved plate 12 and the second curved plate 22 are flush with the bottom of the ton bag; Step 3: The first drive cylinder 61 and the second drive cylinder 71 respectively drive the first clamping plate 11 and the second clamping plate 21 to close to the middle and clamp the ton bag; Step 4: The lifting platform 52 rises along the lifting track 51 to clamp the ton bag. Lift it up to provide a base material for the next step; the fifth step is to discharge the material. The lifting platform 52 descends to a suitable height along the lifting track 51. After the ton bag has a new carrying platform, the first driving cylinder 61 and the second driving cylinder 71 respectively drive the first clamping plate 11 and the second clamping plate 21 to open to both sides, loosening the ton bag on both sides. Then, the lifting platform 52 rises along the lifting track 51. During the rising process, the first rotating rod 3 and the second rotating rod 4 can flatten the front and rear ends of the tilted and deformed ton bag while rotating, so that the ton bag maintains a basically square shape; the first rotating rod 3 and the second rotating rod 4 flatten the ton bag by rolling without puncturing the ton bag.

[0052] The first driving cylinder 61 and the second driving cylinder 71 move independently, respectively, and can move the first clamping plate 11 and the second clamping plate 21 respectively. When the placement position of the ton bag is offset, the first driving cylinder 61 and the second driving cylinder 71 can be used to make the centers of the first clamping plate 11 and the second clamping plate 21 coincide with the center of the ton bag, thereby achieving centered clamping and preventing the ton bag from being clamped at an angle.

[0053] The technical principle of the first rotating rod 3 and the second rotating rod 4 leveling the front and rear surfaces of the ton bag while rotating is as follows: Figure 4 A first fixing block 31 and a second fixing block 32 are respectively provided at both ends of the first rotating rod 3, the first fixing block 31 is provided with a first through hole 311, and the second fixing block 32 is provided with a second through hole 321. The diameter of the first rotating rod 3 is smaller than the diameters of the first through hole 311 and the second through hole 321, that is, the first rotating rod 3 can rotate freely in the first through hole 311 and the second through hole 321; a third fixing block 41 and a fourth fixing block 42 are respectively provided at both ends of the second rotating rod 4, the third fixing block 41 is provided with a third through hole 411, and the fourth fixing block 42 is provided with a fourth through hole 421. The diameter of the second rotating rod 4 is smaller than the diameters of the third through hole 411 and the fourth through hole 421, that is, the second rotating rod 4 can rotate freely in the third through hole 411 and the fourth through hole 421.

[0054] See also Figure 4 In order to limit the travel of the first rotating rod 3 and the second rotating rod 4 in the left and right directions, a first limiting ring 33 and a second limiting ring 34 are provided at one end of the first rotating rod 3, and the first fixing block 31 is provided between the first limiting ring 33 and the second limiting ring 34. A third limiting ring 35 and a fourth limiting ring 36 are provided at the other end of the first rotating rod 3, and the second fixing block 32 is provided between the third limiting ring 35 and the fourth limiting ring 36, wherein the second limiting ring 34 and the fourth limiting ring 36 are respectively fixed to the first rotating rod 3 by screws, that is, the position of the second limiting ring 34 and the fourth limiting ring 36 can be adjusted by adjusting the position of the second limiting ring 34 and the fourth limiting ring 36. A left and right limit stroke of a rotating rod 3; a fifth limit ring 43 and a sixth limit ring 44 are set at one end of the second rotating rod 4, and the third fixed block 41 is set between the fifth limit ring 43 and the sixth limit ring 44; a seventh limit ring 45 and an eighth limit ring 46 are set at the other end of the second rotating rod 4, and the fourth fixed block 42 is set between the seventh limit ring 45 and the eighth limit ring 46, wherein the sixth limit ring 44 and the eighth limit ring 46 are respectively fixed to the second rotating rod 4 by screws, that is, the left and right limit stroke of the second rotating rod 4 can be adjusted by adjusting the positions of the sixth limit ring 44 and the eighth limit ring 46.

[0055] Through Example 2, the clamped ton bag can be lifted and lowered, and its front and rear faces can be flattened during the release of the ton bag. The ton bag can be shaped without puncturing it, providing a basis for the automation of its turnover, inspection and logistics transportation.
