Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to an auxiliary clamping machine. Background Technology

[0002] An auxiliary conveyor belt conveyor is a device used to assist in the material conveying process. When bagging granular materials, a conveying device is usually used to transfer the filled material to the next processing stage. During the material conveying process, auxiliary devices are set on the conveyor belt to ensure the efficiency of material conveying.

[0003] One existing auxiliary clamping machine automatically seals material packaging bags by setting clamping and sealing components near the conveyor belt, thereby accelerating the production process. However, manual setting of the material packaging bags is still required during this process. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an auxiliary bag clamping machine, which aims to solve the problem of needing to manually add bags during material filling.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary clamping machine, comprising a base plate, a bracket fixedly connected to the top of the base plate, a first lifting platform disposed on the front side of the bracket, a conveyor belt fixedly connected to the bottom of the inner wall of the first lifting platform, a storage bin fixedly connected to the front side of the bracket, a mechanical gripper fixedly connected to the bottom of the storage bin, a first driver fixedly disposed on the right side of the storage bin, a connecting rod fixedly connected to the outer surface of the first driver, a second driver fixedly connected to the rear side of the connecting rod, a rack disposed on the front side of the second driver, a first cylinder fixedly connected to the bottom of the connecting rod, a spherical rotating shaft fixedly connected to the bottom of the first cylinder, vacuum suction heads fixedly connected to the outer surfaces of the spherical rotating shaft and the rack, a second lifting platform disposed on the right side of the first lifting platform, multiple packaging bags disposed on the bottom of the inner wall of the second lifting platform, and a limit component disposed on the top of the first lifting platform.

[0006] Preferably, the limiting component includes two connecting plates, which are tightly fitted with the lifting platform. Bolts are threadedly connected between the two connecting plates and the lifting platform. Two cylinders are fixedly connected to opposite sides of each of the two connecting plates. Two baffles are provided between the two connecting plates. Slide grooves are provided on opposite sides of each of the two baffles. Multiple balls are provided at the bottom of each of the two baffles.

[0007] Preferably, both the first and second lifting platforms are fixedly connected to the base plate, and the first and second lifting platforms respectively push the conveyor belt and the packaging bag to move up and down.

[0008] Preferably, the first driver is fixedly connected to the bracket, and the first driver drives the connecting rod to move left and right.

[0009] Preferably, the rack is meshed with the second driver, and the rack moves back and forth under the drive of the second driver.

[0010] Preferably, the gripper portion of the mechanical gripper conforms to the shape of the bottom of the storage bin, and the mechanical gripper holds the packaging bag at the outlet of the storage bin.

[0011] Preferably, the baffle is tightly fitted to the packaging bag, and the bottom of the packaging bag is tightly fitted to the top of the conveyor belt.

[0012] Preferably, both of the slid grooves are slidably connected to two adjacent second cylinders, and the balls are in close contact with the conveyor belt.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, two vacuum adsorption heads are set on the right side of the storage tank. When filling materials, the front vacuum adsorption head adsorbs the packaging bag downwards. By rotating the spherical shaft, the rear vacuum adsorption head also adsorbs the packaging bag. As the two vacuum adsorption heads unfold and expand the packaging bag, the problem of manually adding bags during material filling is solved.

[0015] 2. In this utility model, two baffles are set between the storage tank and the conveyor belt. When filling is carried out, the distance between the two baffles is used to limit the filling. After filling, the two baffles are retracted to the front and rear sides of the conveyor belt by the second cylinder. This does not affect the transportation of the material packaging bags and subsequent work, and solves the problem that the packaging bags are easy to tip over due to uneven loading during the filling process.

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1-3 This utility model provides an embodiment of an auxiliary clamping machine, comprising a base plate 1, a support 2 fixedly connected to the top of the base plate 1, a first lifting platform 5 arranged on the front side of the support 2, a conveyor belt 4 fixedly connected to the bottom of the inner wall of the first lifting platform 5, a storage bin 3 fixedly connected to the front side of the support 2, a mechanical gripper 20 fixedly connected to the bottom of the storage bin 3, a first driver 7 fixedly arranged on the right side of the storage bin 3, a connecting rod 8 fixedly connected to the outer surface of the first driver 7, a second driver 13 fixedly connected to the rear side of the connecting rod 8, a rack 12 arranged on the front side of the second driver 13, a first cylinder 9 fixedly connected to the bottom of the connecting rod 8, a spherical rotating shaft 10 fixedly connected to the bottom of the first cylinder 9, vacuum suction heads 11 fixedly connected to the outer surfaces of both the spherical rotating shaft 10 and the rack 12, a second lifting platform 6 arranged on the right side of the first lifting platform 5, a plurality of packaging bags 14 arranged on the bottom of the inner wall of the second lifting platform 6, and a limit component arranged on the top of the first lifting platform 5.

[0024] Specifically, during material filling, the second lifting platform 6 pushes the stack of packaging bags 14 at the top upwards, while the first cylinder 9 pushes downwards, causing the front vacuum adsorption head 11 to move downwards. After the front vacuum adsorption head 11 adsorbs the material, the spherical rotating shaft 10 drives the packaging bag 14 to turn its direction so that the other side of the packaging bag 14 faces the rear vacuum adsorption head 11. The rear vacuum adsorption head 11 pushes the rack 12 forward through the second driver 13 until it adheres to the packaging bag 14 for adsorption. Then, the second driver 13 pulls the rear vacuum adsorption head 11 backwards to open the packaging bag 14. During the process of opening the packaging bag 14, the first driver 7 drives the connecting rod 8 to move to the left until it reaches the bottom of the storage tank 3. The mechanical gripper 20 clamps the packaging bag 14 on the outer surface of the storage tank 3, and the vacuum adsorption head 11 releases and returns to its original position to adsorb the next packaging bag 14. This solves the problem of manually adding bags during material filling.

[0025] Reference Figure 4 The limiting component includes two connecting plates 15, which are tightly fitted with the lifting platform. Bolts 18 are threadedly connected between the two connecting plates 15 and the lifting platform. Two cylinders are fixedly connected to opposite sides of the two connecting plates 15. Two baffles 17 are provided between the two connecting plates 15. Slide grooves 19 are provided on opposite sides of the two baffles 17. Multiple balls 21 are provided at the bottom of the two baffles 17.

[0026] Specifically, when the packaging bag 14 is fixed at the bottom of the storage tank 3, during the filling process, the two baffles 17 at the bottom of the storage tank 3 are pushed towards the middle under the drive of the second cylinder 16. When the packaging bag 14 is filled with material, the packaging bag 14 is always in an upright state under the restriction of the baffles 17, and the material in the bag can be filled evenly. This prevents the packaging bag 14 from being stretched longitudinally due to excessive material accumulation at the bottom, thus solving the problem that the packaging bag 14 is prone to tipping over due to uneven loading during the filling process.

[0027] Reference Figure 1 The first lifting platform 5 and the second lifting platform 6 are both fixedly connected to the base plate 1. The first lifting platform 5 and the second lifting platform 6 respectively push the conveyor belt 4 and the packaging bag 14 to move up and down.

[0028] Specifically, when filling packaging bags 14 of different sizes and specifications, the first lifting platform 5 is raised to make the conveyor belt 4 fit the packaging bag 14, so that the filled packaging bag 14 can be conveyed to the next process. As the filling work proceeds, the second lifting platform 6 continuously pushes the packaging bags 14 upward to ensure that the front vacuum suction head 11 can adsorb the packaging bag 14.

[0029] Reference Figure 3The first driver 7 is fixedly connected to the bracket 2, and the first driver 7 drives the connecting rod 8 to move left and right.

[0030] Specifically, the rotation of the lead screw in the first driver 7 drives the connecting rod 8 connected to it to move parallel to the bracket 2, thereby bringing the packaging bag 14 to the bottom of the storage bucket 3.

[0031] Reference Figure 3 The rack 12 is meshed with the second driver 13, and the rack 12 moves back and forth under the drive of the second driver 13.

[0032] Specifically, due to the meshing between the rack 12 and the second driver 13, the rack 12 is pushed to move while the vacuum suction head 11 on the rear side moves forward, thus opening the packaging bag 14 through suction.

[0033] Reference Figure 2 The mechanical gripper 20 has a gripper portion that fits the shape of the bottom of the storage bin 3, and the mechanical gripper 20 holds the packaging bag 14 at the outlet of the storage bin 3.

[0034] Specifically, the mechanical gripper 20 is positioned at a higher horizontal level than the two vacuum suction heads 11. When the packaging bag 14 is moved to the outlet of the storage tank 3 by the vacuum suction head 11, the packaging bag 14 is positioned around the outer surface of the storage tank 3. The mechanical gripper 20 clamps and fixes the packaging bag 14 at the outlet of the storage tank 3.

[0035] Reference Figure 4 The baffle 17 is tightly fitted to the packaging bag 14, and the bottom of the packaging bag 14 is tightly fitted to the top of the conveyor belt 4.

[0036] Specifically, the packaging bag 14 is located between the storage bin 3 and the conveyor belt 4. When the packaging bag 14 is being filled, the material being filled into the packaging bag 14 is kept in the same volume from top to bottom by the baffle 17. This prevents the packaging bag 14 from being damaged due to excessive filling at the bottom, which would cause a pulling sensation at the top.

[0037] Reference Figure 4 Both slids 19 are slidably connected to the two adjacent second cylinders 16, and the ball bearings 21 are tightly fitted to the conveyor belt 4.

[0038] Specifically, when the conveyor belt 4 is adjusted up and down, the second cylinder 16 is set in the groove 19 on the baffle 17, so that the baffle 17 moves up and down with the conveyor belt 4 under the action of gravity. When the conveyor belt 4 is conveying, the ball bearing 21 is set between the baffle 17 and the conveyor belt 4 to reduce the friction between the conveyor belt 4 and the baffle 17.

[0039] Working principle: When filling materials, the second lifting platform 6 pushes the top stack of packaging bags 14 upward, while the first cylinder 9 pushes downward, causing the front vacuum adsorption head 11 to move downward. After the front vacuum adsorption head 11 adsorbs, the spherical rotating shaft 10 drives the packaging bag 14 to turn its direction, so that the other side of the packaging bag 14 faces the rear vacuum adsorption head 11. The rear vacuum adsorption head 11 pushes the rack 12 forward through the second driver 13 until it adheres to the packaging bag 14 for adsorption. Then, the second driver 13 pulls the rear vacuum adsorption head 11 backward to open the packaging bag 14. During the process of opening the packaging bag 14, the first driver 7 drives the connecting rod 8 to move to the left until it moves to the bottom of the storage tank 3. The mechanical gripper 20 is at a higher level than the two vacuum adsorption heads 11. The mechanical gripper 20 clamps and fixes the packaging bag 14 at the outlet of the storage tank 3. The vacuum adsorption head 11 is released and returns to its original position to adsorb the next packaging bag 14.

[0040] During the filling process, the packaging bag 14 is located between the storage tank 3 and the conveyor belt 4. When the packaging bag 14 is being filled, the material being filled into the packaging bag 14 is kept in a uniform volume due to the restriction of the baffle 17. This prevents the packaging bag 14 from being damaged due to excessive filling at the bottom and causing a pulling sensation at the top. Furthermore, the packaging bag 14 remains upright under the restriction of the baffle 17 to prevent the material from tipping over.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
