Description

Technical Field

[0001] The utility model relates to the technical field of rice packaging bag clamping, in particular to an adjustable bag holding device. Background Art

[0002] Rice is made from husked paddy rice. The processing generally includes rice milling, polishing, color sorting, grading and packaging. During packaging, the rice is usually packed in bags and then transported and sold bag by bag.

[0003] In the conventional technology, when bagging rice, the packaging bag is generally held tightly by the hand to cover the rice guide tube to receive the rice outputted by the rice guide tube and to put the rice into the packaging bag. However, when the packaging bag is held tightly by the hand, the instantaneous impact force of the rice cannot be withstood by the hand, so that the packaging bag is easily separated from the rice guide tube, resulting in the problem of failure in bagging rice.

[0004] Thus, Chinese patent CN219565677U discloses a rice bag discharging device for a rice mill, wherein two groups of limit slot plate brackets are movably placed horizontally between the two groups of limit slot plate brackets through two groups of horizontal hydraulic rods, and four groups of screw hole transmission bag supporting hooks are movably installed between the two groups of limit slot plate brackets through two groups of bidirectional screw transmission frames, and the inner sides of the hooks of the four groups of screw hole transmission bag supporting hooks are provided with spring compression anti-dropping buckles. When the mouth of the rice bag is rolled up and hooked on the hooks of the four groups of screw hole transmission bag supporting hooks, the four groups of spring compression anti-dropping buckles respectively apply lateral pressure at the hooking force points of the mouth of the rice bag, thereby reducing the risk of the mouth of the rice bag slipping off the hooks of the four groups of screw hole transmission bag supporting hooks under the action of the gravity of the rice contained, thereby improving the practicability of the device.

[0005] However, by comparing the above existing documents and searching the prior art, the inventor believes that the fifth patent still has the following defects:

[0006] In actual use, the comparative document only uses four sets of spring-pressed anti-dropout buckles and hooks to limit the bag opening, which is less effective. At the same time, the spring-pressed anti-dropout mouth itself does not have a limiting structure. If during the rice bagging process, the rice bag itself tilts due to the tilt of the rice stacking position, the rice bag is easy to detach from the spring-pressed anti-dropout buckles and hooks, causing the rice bag to fall over and affecting the bagging efficiency. In view of this, we propose an adjustable bag-supporting device to solve the above problems. Utility Model Content

[0007] In view of the shortcomings of the prior art, the utility model provides an adjustable bag supporting device, which solves the problem that the prior art has a relatively weak effect of limiting the bag opening by only using four sets of spring pressed anti-detachment buckles and hooks during actual use. If the rice bag itself tilts during the rice bagging process, the rice bag is easy to break away from the spring pressed anti-detachment buckles and hooks, thereby causing the rice bag to topple over and affecting the bagging efficiency.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable bag-supporting device, comprising a base, two side plates fixedly mounted on the top of the base, and a fixed cover fixedly mounted on the top of the two side plates, two movable rods are mounted below the fixed cover, a mounting plate is fixedly mounted on the bottom of the movable rod, a connecting plate is fixedly mounted on the bottom of the mounting plate, a positioning plate is fixedly mounted on one side of the connecting plate, a limiting assembly for limiting the opening of the rice packaging bag is arranged on the top of the positioning plate, the limiting assembly comprises a first clamping plate fixedly mounted on the side of the positioning plate away from the connecting plate, the connecting plate The cam is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs,

[0009] Furthermore, the first clamping plate, the second clamping plate and the third clamping plate are all arranged in an arc shape, and an anti-slip pad is fixedly installed on the opposite side of the first clamping plate and the second clamping plate on the same side.

[0010] Furthermore, the heights of the first clamping plate and the third clamping plate are both greater than the height of the second clamping plate, and a plurality of second springs are fixedly installed between the connecting plate and the second clamping plate to facilitate resetting of the second clamping plate.

[0011] Furthermore, a slide groove is provided on the top of the positioning plate, a sliding block extending into the slide groove is fixedly installed on the bottom of the second clamping plate, and an adjusting component for adjusting the spacing between the limiting components is also provided inside the fixed cover.

[0012] Furthermore, the adjustment assembly includes a motor installed on one side of the fixed cover, a screw rod rotatably connected to the side wall of the fixed cover is fixedly installed on the output end of the motor, and the two movable rods are both threadedly installed on the surface of the screw rod.

[0014] Furthermore, a slot is provided at the bottom of the fixed cover to facilitate the movement of the movable rod, and the two movable rods are both slidably connected to the inner wall of the slot.

[0015] Furthermore, four spring rods are fixedly installed on the top of the base, and an adjustment plate for placing the rice packaging bag is fixedly installed on the top of the spring rods.

[0016] Compared with the prior art, the utility model provides an adjustable bag-supporting device, which has the following beneficial effects:

[0017] 1. The adjustable bag-supporting device can support and fix the bag opening of the rice bag by means of the first clamping plate and the second clamping plate, and the contact surface between the first clamping plate and the second clamping plate and the bag opening is larger, so that the device has better stability when fixing the bag opening. At the same time, the slide bar can be limited by the setting of the clamping rod and the clamping groove, so that the second clamping plate is positioned, and the stability of the bag opening is improved. In addition, the bag body can also be limited by the third clamping plate at the same time, so that it is not easy to tip over during the bagging process, and the setting of the first spring also enables the third clamping plate to always fit the bag body, thereby greatly improving the practicality of the device.

[0018] 2. The adjustable bag-supporting device can support the bottom of the bag body through the setting of the adjustment plate. At the same time, the setting of the spring rod allows the position of the adjustment plate to move as the weight of the bag body increases, and the spacing of the limit components can be adjusted through the setting of the adjustment component, so that the device can be suitable for rice bags of different sizes, thereby improving the applicability of the device.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1 and Figure 2 An adjustable bag-supporting device comprises a base 1, two side panels 2 fixedly mounted on the top of the base 1 and a fixed cover 3 fixedly mounted on the top of the two side panels 2, two movable rods 4 are mounted below the fixed cover 3, a mounting plate 5 is fixedly mounted on the bottom of the movable rods 4, a connecting plate 6 is fixedly mounted on the bottom of the mounting plate 5, and a positioning plate 7 is fixedly mounted on one side of the connecting plate 6.

[0028] See also Figure 3 , Figure 4 and Figure 5 A limiting assembly for limiting the opening of the rice packaging bag is provided on the top of the positioning plate 7. The limiting assembly includes a first clamping plate 8 fixedly mounted on the side of the positioning plate 7 away from the connecting plate 6. A sliding rod 11 extending to the top of the positioning plate 7 is inserted on the side of the connecting plate 6 close to the positioning plate 7. A second clamping plate 10 is fixedly mounted on one end of the sliding rod 11 located above the positioning plate 7. A rotating rod 13 is rotatably mounted on the end of the sliding rod 11 away from the second clamping plate 10. Two positioning blocks 16 are also fixedly mounted on the side of the connecting plate 6 away from the positioning plate 7. Two card slots 15 are provided on the side of the positioning block 16 close to the rotating rod 13. Two card rods 14 extending to the corresponding card slots 15 are fixedly mounted on the surface of the rotating rod 13. A plurality of first springs 21 are also fixedly mounted on the side of the first clamping plate 8 away from the positioning plate 7. A third clamping plate 9 is fixedly mounted on the other end of the first spring 21.

[0029] Among them, the first clamping plate 8 and the second clamping plate 10 can be provided to open and fix the bag opening of the rice bag, and the contact surface between the first clamping plate 8 and the second clamping plate 10 and the bag opening is larger, so that the device is more stable when fixing the bag opening.

[0030] In addition, the slide bar 11 can be limited by the arrangement of the clamping rod 14 and the clamping groove 15, so that the second clamping plate 10 is positioned, thereby improving the stability of the bag mouth fixation. At the same time, the bag body can also be limited by the third clamping plate 9, so that it is not easy to tip over during the bagging process, and the arrangement of the first spring 21 also enables the third clamping plate 9 to always fit the bag body, thereby greatly improving the practicability of the device.

[0031] In this embodiment, the first clamping plate 8, the second clamping plate 10 and the third clamping plate 9 are all arc-shaped, and anti-slip pads are fixedly installed on the opposite sides of the first clamping plate 8 and the second clamping plate 10 on the same side. The heights of the first clamping plate 8 and the third clamping plate 9 are greater than the height of the second clamping plate 10, and a plurality of second springs 12 are fixedly installed between the connecting plate 6 and the second clamping plate 10 to facilitate the resetting of the second clamping plate 10.

[0032] The arc-shaped first clamping plate 8, the second clamping plate 10 and the third clamping plate 9 enable the device to better fit the rice bag.

[0033] In addition, the anti-slip pads provide greater friction when the first clamping plate 8 and the second clamping plate 10 are used to open and fix the bag opening, thereby making the bag more stable.

[0034] It is worth noting that when the clamping rod 14 is engaged with the positioning block 16 in the side slot 15 away from the connecting plate 6, the second spring 12 is in a compressed state. When the rotating rod 13 is rotated to make the clamping rod 14 disengage from the slot 15, the second clamping plate 10 will be reset under the elastic force of the second spring 12, thereby forming a clamping fixation on the bag opening with the first clamping plate 8. When the clamping rod 14 is engaged with the positioning block 16 in the side slot 15 close to the connecting plate 6, the positioning of the second clamping plate 10 is completed, thereby improving the stability of the bag opening fixation.

[0035] In this embodiment, a slide groove 22 is further provided on the top of the positioning plate 7 , and a sliding block extending into the slide groove 22 is fixedly mounted on the bottom of the second clamping plate 10 .

[0036] The second clamping plate 10 is made more stable when moving by providing the slide groove 22 and the sliding block.

[0037] See also Figure 6 An adjustment component for adjusting the spacing of the limit components is also provided inside the fixed cover 3. The adjustment component includes a motor 19 installed on one side of the fixed cover 3. A screw rod 20 rotatably connected to the side wall of the fixed cover 3 is fixedly installed at the output end of the motor 19. Both movable rods 4 are threadedly installed on the surface of the screw rod 20.

[0038] The threads on both sides of the screw rod 20 are in opposite directions, and the two movable rods 4 are respectively threadedly mounted on the sides of the screw rod 20 with opposite threads.

[0039] In addition, the starting motor 19 drives the screw rod 20 to rotate so that the two movable rods 4 move in opposite directions, which can be used to open the mouth of the rice bag. The distance between the two first clamping plates 8 and the second clamping plates 10 can also be adjusted to make the device suitable for opening and fixing rice bags of different sizes.

[0040] In this embodiment, a slot is further provided at the bottom of the fixed cover 3 to facilitate the movement of the movable rod 4 , and the two movable rods 4 are both slidably connected to the inner wall of the slot.

[0041] The slots are provided to facilitate the movement of the movable rod 4 and also to limit the position of the movable rod 4, making it more stable when moving.

[0042] See also Figure 1 and Figure 2 In this embodiment, four spring rods 17 are fixedly installed on the top of the base 1, and an adjustment plate 18 for placing rice packaging bags is fixedly installed on the top of the spring rods 17.

[0043] Among them, the bottom of the bag body can be supported by the setting of the adjustment plate 18, and the setting of the spring rod 17 allows the position of the adjustment plate 18 to move as the weight of the bag body increases, thereby facilitating the device to be applied to rice bags of different sizes and improving the applicability of the device.

[0044] When the present embodiment is in use, the motor 19 is started to drive the screw rod 20 to rotate so that the two movable rods 4 move in opposite directions. After the two first clamping plates 8 and the second clamping plates 10 are adjusted to appropriate positions according to the size of the bag opening, the rice bag is placed between the two third clamping plates 9, and the bag opening is rolled up so that the two sides of the bag opening are located between the first clamping plate 8 and the second clamping plate 10 to complete the bag opening opening work, and the rotating rod 13 is rotated to make the clamping rod 14 disengage from the clamping groove 15. At this time, the second clamping plate 10 will be reset under the elastic force of the second spring 12, thereby cooperating with the first clamping plate 8 to limit the bag opening. After the limiting is completed, the rotating rod 13 is rotated to make the clamping rod 14 clamped into the clamping groove 15 on the other side, thereby completing the limiting of the second clamping plate 10, improving the stability of the bag opening fixation, and the two third clamping plates 9 can limit the bag body, so that it is not easy to tip over during the bagging process, and the setting of the first spring 21 also enables the third clamping plate 9 to always fit the bag body, thereby greatly improving the practicality of the device.
