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

[0022] The first clamping plate and the second clamping plate are respectively arranged on the lifting platform through a first moving component and a second moving component.

[0023] Preferably, the lifting platform includes a first guide rail groove and a second guide rail groove;

[0024] The first moving assembly includes a first driving cylinder and a first guide rail. The first guide rail and the first guide rail groove are arranged in cooperation.

[0027] Compared with the prior art, the technical effects of the present invention are as follows:

[0028] (1) The first clamping plate and the second clamping plate constitute the clamping components on both sides of the ton bag, the first curved plate and the second curved plate constitute the bottom lifting component of the ton bag, and the first and second baffles staggered in height direction constitute the blocking components of the front and rear end faces of the ton bag.

[0030] (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.

[0031] (4) The staggered arrangement of the first and second stop bars in the height direction helps to expand the blocking area of ​​the front and rear ends of the ton bag, making it easier for the ton bag to maintain a fixed shape. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Example 1

[0043] 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").

[0044] Ton bag clamping components, reference Figures 1 to 6 As 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 arranged 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 arranged at the end of the second curved plate 22, and the first baffle 13 and the second baffle 23 are staggered in the height direction; the first curved plate 12 and the second curved plate 22 constitute the bottom lifting assembly of the ton bag; a third baffle 14 is arranged in the middle of the first curved plate 12, and a first baffle rod 141 is respectively arranged at both ends of the third baffle rod 14, and a second baffle rod 231 is respectively arranged at both ends of the second baffle rod 23; the first baffle rod 141 and the second baffle rod 231 are staggered in the height direction.

[0045] Specifically, see the diagram of ton bags Figure 4 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.

[0046] 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.

[0047] 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. Because 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. The first stop bar 13 and the second stop bar 23, which are staggered in the height direction, provide space for the first stop bar 141 and the second stop bar 231, which are staggered in the height direction, to avoid interference between the first stop bar 141 and the second stop bar 231; it should be further explained that the first curved plate 12 and the second curved plate 22 are respectively provided with the first stop bar 13 and the 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 1 Angle 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.

[0048] In addition, in order to further achieve the clamping of the ton bag, a third baffle 14 is arranged in the middle of the first curved plate 12, a fourth baffle 15 is arranged above the third baffle 14, and a fifth baffle 24 is arranged above the second baffle 23. The third baffle 14, the fourth baffle 15 and the fifth baffle 24 further achieve the blocking of both sides of the ton bag, especially the two sides near the bottom, to achieve tight holding; 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, the fourth baffle 15 and the fifth 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.

[0049] Thirdly, see Figure 1 and Figure 2, a first baffle 141 is respectively provided at both ends of the third baffle 14, a second baffle 231 is respectively provided at both ends of the second baffle 23, a third baffle 151 is respectively provided at both ends of the fourth baffle 15, and a fourth baffle 241 is respectively provided at both ends of the fifth baffle 24. The first baffle 141, the second baffle 231, the third baffle 151 and the fourth baffle 241 constitute a blocking component for the front end and rear end faces of the ton bag; the first baffle 141 and the second baffle 231 are staggered in the height direction, and the third baffle 151 and the fourth baffle 241 are staggered in the height direction. The staggered setting in the height direction can avoid interference between the baffles on the one hand, and on the other hand, it can expand the blocking range of the baffles to prevent the ton bag from tilting.

[0050] 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.

[0051] Example 2

[0052] See also Figures 1 to 5 Based on Example 1, the ton bag clamping assembly further includes a lifting assembly 3, which includes a lifting rail 31 and a lifting platform 32. The first clamping plate 11 and the second clamping plate 21 are respectively mounted on the lifting platform 32 via a first moving assembly 4 and a second moving assembly 5. The lifting platform 32 includes a first guide rail groove 321 and a second guide rail groove 322. The first moving assembly 4 includes a first drive cylinder 41 and a first guide rail 42. The first guide rail 42 cooperates with the first guide rail groove 321. The first guide rail 42 ends at the top of the first clamping plate 11. The first drive cylinder 41 drives the first guide rail 42 to move along the first guide rail groove 321, thereby moving the first clamping plate 11. The second moving assembly 5 includes a second drive cylinder 51 and a second guide rail 52. The second guide rail 52 cooperates with the second guide rail groove 322. The second guide rail 52 ends at the top of the second clamping plate 21. The second drive cylinder 51 drives the second guide rail 52 to move along the second guide rail groove 322, thereby moving the second clamping plate 21.

[0053] Specifically, see Figures 1 to 5The first drive cylinder 41 and the second drive cylinder 51 are preferably electric cylinders. On the one hand, the electric cylinders have high control accuracy, and on the other hand, the electric cylinders do not produce oil pollution; the first drive cylinder 41 independently drives the first clamping plate 11 to move left and right along the first guide rail groove 321, and the second drive cylinder 51 independently drives the second clamping plate 21 to move left and right along the second guide rail groove 322. The process of clamping the ton bag is as follows: Step 1: The ton bag is placed under the lifting platform 32, and the first driving cylinder 41 and the second driving cylinder 51 respectively drive the first clamping plate 11 and the second clamping plate 21 to open to both sides, and the first clamping plate 11 synchronously drives the first block rod 141 and the third block rod 151 to move, and the second clamping plate 21 synchronously drives the second block rod 231 and the fourth block rod 241 to move; Step 2, the lifting platform 32 descends along the lifting rail 31, so that the first clamping plate 11 and the second clamping plate 21 descend, and the lowering is stopped when the ends of the first curved plate 12 and the second curved plate 22 are flush with or close to the bottom of the ton bag; Step 3, the first driving cylinder 41 and the second driving cylinder 51 respectively drive the first clamping plate 11 and the second clamping plate 21 to close to the middle and clamp the ton bag, and the first block rod 141 and the third block rod 151 block the left half of the front and rear end faces of the ton bag during the movement, and the second block rod 231 and the fourth block rod 241 block the front and rear end faces of the ton bag during the movement. In the right half of the bag, the first stop bar 141, the second stop bar 231, the third stop bar 151 and the fourth stop bar 241 block the front and rear end faces of the ton bag in a staggered manner in the height direction; fourth, the lifting platform 32 rises along the lifting rail 31 to lift the clamped ton bag and provide a base material for the next action; fifth step, unloading, the lifting platform 32 descends to a suitable height along the lifting rail 31, and after the ton bag has a new carrying platform, the first driving cylinder 41 and the second driving cylinder 51 respectively drive the first clamping plate 11 and the second clamping plate 21 to open to both sides, release the ton bag on both sides, and synchronously drive the first stop bar 141, the second stop bar 231, the third stop bar 151 and the fourth stop bar 241 to leave the ton bag, and then the lifting platform 32 rises along the lifting rail 31 to prepare for the next ton bag lifting operation; the first stop bar 141, the second stop bar 231, the third stop bar 151 and the fourth stop bar 241 have the function of leveling the ton bag without puncturing the ton bag.

[0054] The first driving cylinder 41 and the second driving cylinder 51 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 41 and the second driving cylinder 51 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.

[0055] See also Figure 5 and Figure 6, in order to make the first blocking rod 141, the second blocking rod 231, the third blocking rod 151 and the fourth blocking rod 241 further reduce the resistance and block the front and rear end faces of the ton bag, the ends of the first blocking rod 141, the second blocking rod 231, the third blocking rod 151 and the fourth blocking rod 241 are all provided with an outward-facing arc-shaped portion 6, and a guide wheel 61 is provided on the arc-shaped portion 6, and the guide wheel 61 rolls along the surface of the ton bag. The guide wheel 61 can be a wheel or a bull's eye bearing. The rolling surface of the guide wheel 61 protrudes from the surfaces of the first blocking rod 141, the second blocking rod 231, the third blocking rod 151 and the fourth blocking rod 241; the end of the arc-shaped portion 6 faces outward, and in the process of contacting with the ton bag, it is the arc-shaped portion 6 that contacts and will not puncture the ton bag; in addition, in order to further reduce the resistance, a guide wheel 61 is provided on the arc-shaped portion 6, and the guide wheel 61 will roll out a groove on the surface of the ton bag during the process of rolling along the ton bag. The groove plays a guiding role, and the subsequent blocking rods will move along the groove without puncturing the ton bag.

[0056] See also Figure 5 In order to further reduce the friction between the barrier rod and the ton bag and prevent the ton bag from being punctured, the angle between the first barrier rod 141 and the third barrier bar 14 is 95° to 110°, the angle between the second barrier rod 231 and the second barrier bar 23 is 95° to 110°, the angle between the third barrier rod 151 and the fourth barrier bar 15 is 95° to 110°, and the angle between the fourth barrier rod 241 and the fifth barrier bar 24 is 95° to 110°. Figure 5 When the included angle is obtuse, the width of the barrier bar is the largest when it contacts the bag, and then the barrier bar gradually tightens the front and rear end surfaces of the bag during the clamping process to prevent the bag from being punctured.

[0057] Through Example 2, the clamped ton bag can be lifted and lowered, and the front and rear end faces of the ton bag can be kept basically flat by the first barrier rod 141, the second barrier rod 231, the third barrier rod 151 and the fourth barrier rod 241 which are staggered in the height direction. The shaping of the ton bag is achieved without puncturing the ton bag, providing a basis for the automation of its turnover, inspection and logistics transportation.
