Description

Technical Field

[0001] This utility model relates to a mobile bag clamping structure for a ton bag machine, specifically a mobile bag clamping structure for a fully automatic ton bag machine. Background Technology

[0002] Existing ton bag machine mobile clamping mechanism typically includes two clamping jaws, left and right. Each clamping jaw is connected to an independent cylinder. The opening and closing of the clamping jaw is driven by the extension and retraction of the cylinder. The left and right clamping jaws clamp the two sides of the ton bag opening under the drive of the cylinder. Each clamping jaw is equipped with a clamping plate to clamp the ton bag opening and ensure the firmness of the bag opening during movement.

[0003] When clamping the bag opening, the bag opening may deform during the clamping process. Since the existing clamping plate is a straight surface, some parts of the bag opening are not completely clamped, leaving gaps. This results in some bag openings not being fully clamped, causing the bag opening to fall off during the movement, thus affecting the quality of the heat sealing of the bag opening when it is clamped to the heat sealing point. Utility Model Content

[0004] In order to solve the problems in related technologies, this utility model provides a mobile bag clamping structure for a fully automatic ton bag machine. This device solves the problem that existing mobile bag clamping mechanisms do not clamp completely, and some or all of them fall off during the movement, resulting in the bag opening not being fully delivered to the heat sealing component to achieve complete sealing of the bag opening, thus affecting the quality of the finished product.

[0005] To solve the above problems, the following technical solutions are provided:

[0006] The mobile bag clamping structure of the fully automatic ton bag machine includes a bag clamping mechanism, which includes a bag clamping bracket, two bag clamping rods, and two first drive components. One end of each bag clamping rod is hinged to the bag clamping bracket. The first drive components are linked to the hinged ends of the bag clamping rods in a one-to-one correspondence. The first drive components are used to drive the bag clamping rods to rotate, so that the two bag clamping rods are in a separated or clamped state. The characteristic is that a first clamping plate and a second clamping plate are respectively provided on the side surfaces of the two bag clamping rods that are close to each other. The first clamping plate is a male plate, and the second clamping plate is a female plate that is adapted to the male plate.

[0007] Through the above technical solution, with the design of the first clamping plate and the second clamping plate, the first clamping plate being the male plate and the second clamping plate being the female plate, when the two clamping rods are in a clamping state, the first clamping plate and the second clamping plate can tightly fit the bag mouth of the ton bag, ensuring that the bag mouth of the ton bag is completely compressed during the clamping process. This avoids uneven clamping caused by the straight surface of the clamping plates and avoids the problem of the bag mouth partially or completely falling off during the movement, thereby improving the firmness and reliability of the ton bag mouth sealing, ensuring the subsequent heat sealing effect of the bag mouth, and thus improving the quality of the finished product.

[0008] Furthermore, it also includes a conveying mechanism for moving the bag clamping mechanism. The conveying mechanism includes a conveyor frame. Limit position detection components are respectively provided at both ends of the conveyor belt along its length. The bag clamping mechanism moves along the conveyor frame between the two limit position detection components. There are two parallel guide rails arranged vertically and vertically on the side of the conveyor frame near the bag clamping mechanism along its width. The guide rails are arranged along the length of the conveyor frame and there is a gap between the two guide rails.

[0009] The bag clamping mechanism is slidably engaged with the conveying mechanism via a connecting mechanism; the connecting mechanism includes a first support plate and a roller, a limit rod is provided on the side of the first support plate near the bag clamping mechanism, one end of the limit rod is fixedly connected to the bag clamping bracket, the side of the first support plate near the conveying mechanism is rotatably engaged with the roller, and the roller is rotatably disposed between the two guide rails.

[0010] By using the above technical solution and setting the limit position detection component, it is possible to prevent the bag clamping mechanism from moving excessively, causing it to detach from the conveying mechanism, which could lead to equipment damage and safety issues. This ensures the normal use of the equipment, guarantees safety, and reduces costs.

[0011] By positioning the rollers between the two guide rails, a limit can be provided for the bag clamping mechanism as it moves along the conveying direction of the conveying mechanism, ensuring that the bag clamping mechanism will not deviate during its movement, thereby improving the stability and reliability of the bag clamping mechanism's operation.

[0012] By setting the limiting rod, when the first drive assembly drives the bag clamping rod to rotate and the two bag clamping rods separate, as the bag clamping rod continues to rotate, it will hit the side wall of the limiting rod, thereby limiting the bag clamping rod from continuing to rotate beyond the predetermined angle, thus ensuring that the bag clamping rod always works within a safe and effective range of motion.

[0013] Furthermore, the conveying mechanism also includes a conveyor belt assembly and a second drive assembly. The conveyor belt assembly includes a driving wheel, a driven wheel, and a conveyor belt that drives the driving wheel and the driven wheel. The driving wheel and the driven wheel are both rotatably engaged with the conveyor belt. The second drive assembly is fixed on the conveyor frame and is connected to the driving wheel. The second drive assembly is used to drive the driving wheel to rotate.

[0014] The first support plate has a first connecting plate at its top, one end of which extends toward the conveyor belt and is located above the conveyor belt. The first connecting plate has a pressure plate at its bottom, and a pressure groove is provided at the lower part of the pressure plate. The width of the pressure groove is the same as the width of the conveyor belt. A toothed plate is connected to the bottom of the pressure plate, and the toothed plate is detachably connected to the pressure plate. The top of the toothed plate has multiple strip teeth. The toothed plate installed on the pressure plate covers part of the pressure groove, and the depth of the uncovered pressure groove is less than the thickness of the conveyor belt.

[0015] The above technical solution, through the setting of pressure plate and toothed plate, ensures that when the conveyor belt is installed in the pressure groove between the toothed plate and the pressure plate, the strip teeth can firmly press the conveyor belt in the pressure groove, avoiding the offset between the pressure plate and toothed plate and the conveyor belt during the conveying process of the bag clamping mechanism, thereby ensuring the accurate conveying of the bag clamping mechanism and improving the clamping effect of the ton bag mouth.

[0016] Furthermore, the first driving assembly includes a driving cylinder, a first support member is fixedly disposed on the limiting rod, the driving cylinder is hinged to the first support member, and the bag clamping rod and the corresponding driving cylinder are disposed on opposite sides.

[0017] The above technical solution, with the bag clamping rod and driving cylinder set on opposite sides, can achieve an efficient layout in a limited space, avoiding the waste of space caused by single-sided setting, thus making the bag clamping mechanism more compact and saving installation space.

[0018] Furthermore, the bag clamping bracket includes a second support member and two connecting brackets with identical structures. The second support member is arranged along the conveying direction of the conveying mechanism and is fixedly connected to the limiting rod. The connecting brackets are arranged in an "L" shape. The junction of the connecting brackets is rotatably connected to the second support member. One end of the connecting bracket is fixedly connected to the limiting rod, and the other end of the connecting bracket is fixedly connected to the corresponding bag clamping rod.

[0019] The bottom of the connecting bracket that is hinged to the second support member has an extension plate, and a second connecting plate is fixedly installed on the extension plate. The second connecting plate is L-shaped. The vertical section of the second connecting plate is fixedly connected to the bottom of the extension plate. A spherical bearing is installed in the gap between the extension plate and the horizontal section of the second connecting plate. The spherical bearing is rotatably engaged with the extension plate and the second connecting plate respectively. The output end of the drive cylinder is fixedly connected to the corresponding spherical bearing.

[0020] Through the above technical solution, by setting the joint bearing on the extension plate, the joint bearing can effectively reduce the shaking and vibration of the bag clamping rod during rotation, thereby improving the smoothness and reliability of the bag clamping mechanism.

[0021] Furthermore, a baffle is provided above the connecting bracket, and the baffle is fixedly engaged with the limiting plate.

[0022] The above technical solution, through the setting of the baffle, can prevent dust or impurities from falling on the bag clamping mechanism, thereby ensuring that no dust or impurities enter the hinge of the bag clamping mechanism, thus ensuring that the bag clamping mechanism can operate normally.

[0023] Furthermore, the second driving component includes a driving motor, which is fixed at one end of the conveying mechanism along its length, and one end of the driving mechanism is positioned toward the bag clamping mechanism. The section of the driving mechanism positioned toward the bag clamping mechanism forms a rigid limiting member for restricting the movement of the bag clamping mechanism.

[0024] The other end of the conveyor frame along its length has a limiting block for restricting the movement of the bag clamping mechanism. The limiting block is set on the side of the conveyor frame corresponding to one side of the guide rail, and is located on the side of the conveyor frame close to the bag clamping mechanism. The two limit position detection components are located between the limiting block and the drive motor.

[0025] Through the above technical solution, by setting up hard limiters and limit blocks, when the two extreme position detection components fail, the hard limiters and limit blocks can respectively prevent the bag clamping mechanism from detaching from the conveying mechanism, thereby ensuring the integrity of the bag clamping mechanism and avoiding safety accidents, thus reducing costs and ensuring safety.

[0026] The above solution has the following advantages:

[0027] 1. By setting up the first clamping plate and the second clamping plate, with the first clamping plate being the male plate and the second clamping plate being the female plate, when the two clamping rods are in a clamping state, the first clamping plate and the second clamping plate can tightly fit the bag mouth of the ton bag, ensuring that the bag mouth of the ton bag is completely compressed during the clamping process. This avoids uneven clamping caused by the straight surface of the clamping plates and avoids the problem of the bag mouth partially or completely falling off during the movement. In this way, the firmness and reliability of the ton bag mouth sealing are improved, ensuring the subsequent heat sealing effect of the bag mouth, thereby improving the quality of the finished product.

[0028] 2. By setting the limit position detection component, the bag clamping mechanism can be prevented from moving excessively, causing it to detach from the conveying mechanism, which could lead to equipment damage and safety issues. This ensures the normal use of the equipment, guarantees safety, and reduces costs.

[0029] By positioning the rollers between the two guide rails, a limit can be provided for the bag clamping mechanism as it moves along the conveying direction of the conveying mechanism, ensuring that the bag clamping mechanism will not deviate during its movement, thereby improving the stability and reliability of the bag clamping mechanism's operation.

[0030] By setting the limiting rod, when the first drive assembly drives the bag clamping rod to rotate and the two bag clamping rods separate, as the bag clamping rod continues to rotate, it will hit the side wall of the limiting rod, thereby limiting the bag clamping rod from continuing to rotate beyond the predetermined angle, thus ensuring that the bag clamping rod always works within a safe and effective range of motion.

[0031] 3. By setting up the pressure plate and toothed plate, it can be ensured that when the conveyor belt is installed in the pressure groove between the toothed plate and the pressure plate, the strip teeth can firmly press the conveyor belt in the pressure groove, avoiding the offset between the pressure plate and toothed plate and the conveyor belt during the conveying process of the bag clamping mechanism, thereby ensuring the accurate conveying of the bag clamping mechanism and improving the clamping effect of the ton bag mouth.

[0032] 4. With the bag clamping rod and drive cylinder set on opposite sides, the opposite side setting can achieve an efficient layout in a limited space, avoiding the waste of space caused by the single-sided setting, thus making the bag clamping mechanism more compact and saving installation space.

[0033] 5. By incorporating spherical bearings on the extension plate, the spherical bearings can effectively reduce the swaying and vibration of the bag clamping rod during rotation, thereby improving the smoothness and reliability of the bag clamping mechanism.

[0034] 6. By setting up the baffle, dust or impurities can be prevented from falling on the bag clamping mechanism, thus ensuring that no dust or impurities enter the hinge of the bag clamping mechanism, thereby ensuring that the bag clamping mechanism can operate normally.

[0035] 7. By setting up hard limiters and limit blocks, when the two extreme position detection components fail, the hard limiters and limit blocks can respectively prevent the bag clamping mechanism from detaching from the conveying mechanism, thereby ensuring the integrity of the bag clamping mechanism and avoiding safety accidents, thus reducing costs and ensuring safety.

[0049] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0050] In a specific embodiment, such as Figure 1-9As shown, the moving bag-clamping structure of the fully automatic ton bag machine includes a bag-clamping mechanism, which comprises a bag-clamping bracket 1, two bag-clamping rods 2, and two first drive components 3. The first drive components 3 are adapted and connected to a controller on the fully automatic ton bag machine. The presence of a controller on the fully automatic ton bag machine is conventional technology and will not be elaborated upon here. Controlling the first drive components 3 through the controller of the fully automatic ton bag machine is also a conventional technical means and will not be elaborated upon here. One end of each bag-clamping rod 2 is hinged to the bag-clamping bracket 1, and the first drive components 3 are connected to the hinged ends of the bag-clamping rods 2 in a one-to-one correspondence. The first driving component 3 is used to drive the bag clamping rod 2 to rotate, so that the two bag clamping rods 2 are in a separated or clamped state. The two bag clamping rods 2 are respectively provided with a first clamping plate 4 and a second clamping plate 5 on their adjacent side surfaces. The first clamping plate 4 and the second clamping plate 5 are both provided with teeth on their adjacent side surfaces. The first clamping plate 4 is a male plate and the second clamping plate 5 is a female plate that is adapted to the male plate. In this specific embodiment, the bag clamping rod 2 is a plate with an approximate channel steel shape. The first clamping plate 4 and the second clamping plate 5 are respectively installed on the side surfaces of the corresponding bag clamping rod 2 by bolts.

[0051] When the two clamping rods 2 are in a clamped state, the first clamping plate 4 and the second clamping plate 5 can fit tightly against the bag mouth of the ton bag, ensuring that the bag mouth of the ton bag is completely compressed during the clamping process. This avoids the problem of uneven clamping caused by the direct surface of the heat sealing plate, and avoids the problem of the bag mouth partially or completely falling off during the process of the clamping mechanism clamping the ton bag and moving the ton bag. This improves the firmness and reliability of the ton bag mouth sealing, ensures the subsequent heat sealing effect of the bag mouth, and thus improves the quality of the finished product.

[0052] The mobile bag clamping structure of the fully automatic ton bag machine also includes a conveying mechanism for driving the bag clamping mechanism to move. The conveying mechanism includes a conveyor frame 6, and limit position detection components 7 are respectively provided at both ends of the conveyor belt 14 along its length. The bag clamping mechanism moves along the conveyor frame 6 between the two limit position detection components 7. In this specific embodiment, the limit position detection component 7 includes a position sensor. The limit position detection component 7 can prevent the bag clamping mechanism from moving excessively, causing the bag clamping mechanism to detach from the conveying mechanism, which would lead to equipment damage and affect safety, thereby ensuring the normal use of the equipment, ensuring safety, and reducing costs. The specific structure and connection method of the conveying mechanism are all existing technologies and will not be described in detail here. It is sufficient to select a model that can achieve the conveying function.

[0053] On the side facade of the conveyor frame 6 near the bag clamping mechanism in the width direction, there are two parallel guide rails 8 arranged vertically in sequence. The guide rails 8 are arranged along the length direction of the conveyor frame 6, and there is a gap between the two guide rails 8.

[0054] The bag clamping mechanism is slidably coupled to the conveying mechanism via a connecting mechanism. The connecting mechanism includes a first support plate 9 and a roller 10. A limit rod 11 is provided on the side of the first support plate 9 near the bag clamping mechanism. One end of the limit rod 11 is fixedly connected to the bag clamping bracket 1. When the first drive assembly 3 drives the bag clamping rod 2 to rotate, causing the two bag clamping rods 2 to separate, as the bag clamping rod 2 continues to rotate, it will hit the side wall of the limit rod 11, thereby limiting the bag clamping rod 2 from continuing to rotate beyond a predetermined angle, thus ensuring that the bag clamping rod 2 always works within a safe and effective range of motion. The side of the first support plate 9 near the conveying mechanism is rotatably coupled to the roller 10, which is rotatably disposed between two guide rails 8. The roller 10, located between the two guide rails 8, can provide a limit when the bag clamping mechanism moves along the conveying direction of the conveying mechanism, ensuring that the bag clamping mechanism does not deviate during movement, thereby improving the stability and reliability of the bag clamping mechanism.

[0055] The conveying mechanism also includes a conveyor belt 14 assembly and a second drive assembly 15. The conveyor belt 14 assembly includes a drive wheel 12, a driven wheel 13, and a conveyor belt 14 that drives the drive wheel 12 and the driven wheel 13. The drive wheel 12 and the driven wheel 13 are both rotatably engaged with the conveyor belt 14. The second drive assembly 15 is fixed on the conveyor frame 6 and is connected to the drive wheel 12. The second drive assembly 15 is used to drive the drive wheel 12 to rotate.

[0056] The second drive assembly 15 includes a drive motor, which is fixed at one end of the conveying mechanism along its length. One end of the drive mechanism faces the bag clamping mechanism, and the section of the drive mechanism facing the bag clamping mechanism forms a rigid stop for restricting the movement of the bag clamping mechanism. The other end of the conveying frame 6 along its length has a limit block 26 for restricting the movement of the bag clamping mechanism. The limit block 26 is located on the side of the conveying frame 6 corresponding to one side of the guide rail 8, and is located on the side of the conveying frame 6 near the bag clamping mechanism. Two extreme position detection components 7 are located between the limit block 26 and the drive motor. When the two extreme position detection components 7 fail, the rigid stop and the limit block 26 can respectively prevent the bag clamping mechanism from detaching from the conveying mechanism, thereby ensuring the integrity of the bag clamping mechanism and avoiding safety accidents, thus reducing costs and ensuring safety.

[0057] The driving wheel 12 is concentrically fixed to a first rotating shaft, and the driven wheel 13 is concentrically fixed to a second rotating shaft. The drive motor is used to drive the first rotating shaft to rotate.

[0058] A first connecting plate 16 is provided on the top of the first support plate 9. One end of the first connecting plate 16 extends towards the conveyor belt 14 and is located above the conveyor belt 14. A pressure plate 17 is provided at the bottom of the first connecting plate 16. A pressure groove 18 is provided at the lower part of the pressure plate 17. The width of the pressure groove 18 is the same as the width of the conveyor belt 14. A toothed plate 19 is connected to the bottom of the pressure plate 17. The toothed plate 19 is detachably connected to the pressure plate 17. A plurality of strip teeth 20 are provided on the top of the toothed plate 19. The toothed plate 19 mounted on the pressure plate 17 partially covers the pressure groove 18, and the depth of the uncovered pressure groove 18 is less than the thickness of the conveyor belt 14. When the conveyor belt 14 is installed in the pressure groove 18 between the toothed plate 19 and the pressure plate 17, the strip teeth 20 can firmly press the conveyor belt 14 into the pressure groove 18, preventing the pressure plate 17 and toothed plate 19 from shifting from the conveyor belt 14 during the bag clamping mechanism, thereby ensuring the accurate conveying of the bag clamping mechanism and improving the clamping effect of the ton bag mouth.

[0059] The first driving assembly 3 includes a driving cylinder. A first support member 21 is fixedly mounted on the limiting rod 11. The driving cylinder and the first support member 21 are hinged together. In this specific embodiment, the first support member 21 includes two first support rods. One end of the first support rod is fixedly connected to the limiting rod 11, and the other end of the first support rod is hinged together with the driving cylinder. The bag clamping rod 2 and the corresponding driving cylinder are arranged on opposite sides. The bag clamping rod 2 and the driving cylinder arranged on opposite sides can achieve an efficient layout in a limited space, avoiding space waste caused by unilateral arrangement, thereby making the bag clamping mechanism more compact and saving installation space.

[0060] The bag clamping bracket 1 includes a second support member 101 and two connecting brackets 102 with identical structures. The second support member 101 is arranged along the conveying direction of the conveying mechanism and is fixedly connected to the limiting rod 11. The connecting brackets 102 are arranged in an "L" shape. The junction of the connecting brackets 102 is rotatably connected to the second support member 101. One end of the connecting bracket 102 is fixedly connected to the limiting rod 11, and the other end of the connecting bracket 102 is fixedly connected to the corresponding bag clamping rod 2.

[0061] The bottom of the connecting bracket 102, which is hinged to the second support member 101, has an extension plate 22. A second connecting plate 23 is fixedly installed on the extension plate 22. The second connecting plate 23 is L-shaped. The vertical section of the second connecting plate 23 is fixedly connected to the bottom of the extension plate 22. A spherical bearing 24 is installed in the gap between the horizontal section of the extension plate 22 and the second connecting plate 23. The spherical bearing 24 is rotatably engaged with the extension plate 22 and the second connecting plate 23 respectively. The output end of the drive cylinder is fixedly connected to the corresponding spherical bearing 24. The spherical bearing 24 can effectively reduce the shaking and vibration of the bag clamping rod 2 during rotation, thereby improving the stability and reliability of the bag clamping mechanism.

[0062] A baffle 25 is provided above the connecting bracket 102, and the baffle 25 is fixedly engaged with the limiting plate. The baffle 25 can prevent dust or impurities from falling on the bag clamping mechanism, thereby ensuring that no dust or impurities enter the hinge of the bag clamping mechanism, thus ensuring that the bag clamping mechanism can operate normally.

[0063] Operation process: The conveying mechanism moves the bag clamping mechanism to the position for subsequent placement of ton bags. Two drive cylinders drive two bag clamping rods to rotate around the hinge, causing the two bag clamping rods to separate. At this time, the mouth of the ton bag is placed between the two bag clamping rods. After placement, the two drive cylinders drive the two bag clamping rods to rotate in opposite directions around the hinge, causing the two bag clamping rods to press the mouth of the ton bag. At this time, the first clamping plate and the second clamping plate on the two bag clamping rods press the mouth of the ton bag tightly. After completion, the two drive cylinders drive the two bag clamping rods to rotate around the hinge, causing the two bag clamping rods to separate, and the sealed ton bag is taken away.
