Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to a self-cleaning pier bag hand grab. Background Art

[0002] Bulk materials are susceptible to contamination, moisture, and contamination during transportation. Directly stacking bulk materials onto transport vehicles can cause damage, such as scratches and abrasion. This is where bulk bags come in handy. These are common containers used in material handling, primarily for transporting bulk materials. They collect bulk materials for easy transport and handling, effectively reducing loading and unloading times and improving the efficiency of the entire material handling process.

[0003] During the bagging process, after the material is collected in the bag, it is handled using a handgrip. This typically requires a lifting mechanism, which uses a handgrip to lift the bag and move it to the designated location. During transportation, belt conveyors, roller conveyors, or chain conveyors are used to drive the bag.

[0004] Currently, existing pier-wrapped handgrips typically feature a main shaft assembly with a secondary shaft assembly suspended from its lower end. Rotation of the main shaft assembly drives the secondary shaft assembly below it in synchronous rotation via a primary connecting bracket. The secondary shaft assembly is typically attached to a secondary connecting bracket, which houses two sets of handgrips. These secondary connecting brackets also feature a horizontal power assembly that drives the two handgrips toward or away from each other. This horizontal power assembly is typically implemented using a pneumatic or hydraulic cylinder in conjunction with a slide rail.

[0005] The partial bag gripping action is that after the gripper grips the bag, the gripper assembly rotates the gripper and simultaneously drives the upper edge of the bag to rotate, forming a twisting closure at the top of the bag. The rotation of the gripper assembly is achieved through the cooperation of the driving gear and the driven gear.

[0006] During operation, this type of bag-handling system, which features a twisted top-sealed bag, is subject to dust and impurities present in the loading and transport environment. This dust and impurities can also float upwards with the airflow during the bag-handling process. This dust and impurities can accumulate and adhere to the gears and jaws of the bag-handling system, requiring manual cleaning. Long-term accumulation can also cause the jaws to stagnate, leading to conveying problems.

[0007] Therefore, it is necessary to further improve the structure of the existing pier bag hand grab to address this problem so that it can better adapt to automated conveying operations. Utility Model Content

[0008] The technical problem to be solved by the present invention is: in order to overcome the deficiencies of the existing technology, the present invention provides a self-cleaning pier bag hand grip, which can automatically realize air blowing cleaning at the gear position and the clamping position inside the hand grip assembly. At the same time, the air blowing cleaning utilizes the channel formed by the driving gear teeth and the driven gear of the hand grip assembly, which can be conveniently modified on the basis of the existing hand grip assembly with low modification cost.

[0009] The technical solution adopted by the utility model to solve its technical problems is: a self-cleaning pier bag hand grab, including a main shaft rotating assembly and a secondary shaft rotating assembly, the main shaft rotating assembly has a rotating main shaft, the secondary shaft rotating assembly includes a secondary connecting bracket and a hand grab assembly separately arranged on the secondary connecting bracket, the hand grab assembly includes a hand grab connecting plate, a secondary shaft driving gear, and a secondary shaft driven gear, the secondary shaft driven gear is rotatably arranged on the hand grab connecting plate, the inner ring of the secondary shaft driving gear has a tooth shape, the secondary shaft driving gear is arranged on the inner ring of the secondary shaft driving gear, and the secondary shaft driving gear The outer ring of the wheel has a tooth shape, which meshes with the tooth shape of the inner ring of the secondary shaft driving gear; the hand-grabbing connecting plate is provided with an air duct, one end of the air duct is connected to an air source, and the other end points to the inner side of the gear ring of the secondary shaft driven gear; the outer ring of the secondary shaft driven gear is circumferentially fixed with a pier connection support plate, and the lower end of the pier connection support plate is connected to a number of pier clamping claws; the pier connection support plate is a cylindrical structure with a hollow interior and an inner cavity, the inner space of the gear ring of the secondary shaft driven gear is connected to the inner cavity of the cylindrical structure, and the bottom of the pier connection support plate is provided with an air vent.

[0010] In the above scheme, the space formed by the inner ring of the secondary shaft driven gear of the hand-grabbing assembly is coordinated with the inner cavity and the air vent of the pier bag connecting support plate, and the design of the air duct is coordinated to form an effective air path. When the air duct introduces pressurized gas into the air path, the pressurized gas can blow the tooth profiles of the secondary shaft driven gear and the secondary shaft driving gear, and the dust and impurities on their surfaces fall off and are discharged outward along the air path. This action does not require manual cleaning and can be operated automatically.

[0011] Furthermore, the hand grip assembly includes a countershaft power mechanism, the output end of which is fixed to the countershaft driving gear. The countershaft power mechanism is a reduction motor. The reduction motor drives the countershaft driving gear to rotate, and the rotation of the countershaft driving gear drives the countershaft driven gear to rotate, thereby driving the synchronous rotation of the pier bag connecting support plate fixed to the countershaft driven gear, thereby driving the synchronous rotation of the pier bag clamping claw below.

[0012] Furthermore, the end of the air duct is connected to a guide air vent, which is a downward-slanting groove-shaped structure. One end of the groove structure is connected to the air duct, and the other end is a through-hole pointing toward the lower end face of the inner ring of the secondary shaft driven gear. The top opening of the groove structure points toward the teeth of the secondary shaft driving gear. The configuration of the guide air vent not only guides the pressurized air in the air duct downward through the groove structure, but also utilizes the top opening of the groove structure to direct part of the airflow toward the secondary shaft driving gear, thereby facilitating the removal of dust accumulated on the surface teeth of the secondary shaft driving gear.

[0013] Furthermore, a plurality of air guide holes are formed at the bottom of the groove structure of the air guide port in the direction corresponding to the inner ring of the secondary shaft driven gear. The air guide holes are designed to facilitate dust cleaning operations at the rear side of the air guide port.

[0014] Preferably, the air guide hole is an oblong hole, which is arranged to correspond to the tooth shape of the inner ring of the secondary shaft driven gear.

[0015] Furthermore, the pier bag clamp is fixed at the bottom of the pier bag connecting support plate, and the pier bag clamp is arranged around the vent; the top surface of the pier bag clamp has an exhaust groove, one end of the exhaust groove is connected to the vent, and the other end extends outward along the pier bag clamp and points to the outer periphery of the pier bag.

[0016] The beneficial effect of the utility model is that the utility model provides a group cleaning type pier bag hand grip with a reasonable structural design. A guide pipe is designed on the auxiliary connecting bracket, and the air source is connected through the guide pipe to provide pressurized gas for the guide air outlet, which can be used to blow the gears of the hand grip assembly. After blowing, the gas forms a channel along the pier bag connecting support plate and falls to the pier bag clamping claw, and is discharged outward from the exhaust groove on the surface of the clamping claw. It has a good self-cleaning function, does not require manual dust sweeping, reduces the occurrence of faults caused by dust accumulation inside the hand grip, and is beneficial to the automated design of the conveying unit.

DETAILED DESCRIPTION

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams that illustrate the basic structure of the present invention only in a schematic manner. Therefore, they only show components relevant to the present invention, and directions and references (e.g., up, down, left, right, etc.) may be used solely to facilitate the description of features in the drawings. The following detailed description is therefore not to be taken in a limiting sense, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0024] like Figures 1 to 3 The self-cleaning pile bag grab shown is the best embodiment of the utility model.

[0025] The self-cleaning pier bag hand grip comprises a main shaft rotating assembly 1 and a secondary shaft rotating assembly 2. The main shaft rotating assembly 1 has a rotating main shaft, and the secondary shaft rotating assembly 2 comprises a secondary connecting bracket and a hand grip assembly separately arranged on the secondary connecting bracket.

[0026] The hand-grip assembly includes a hand-grip connecting plate 9, a countershaft driving gear 5, a countershaft driven gear 8, and a countershaft power mechanism. The countershaft driven gear 8 is rotatably mounted on the hand-grip connecting plate 9. The inner ring of the countershaft driving gear 5 has a tooth profile, and the countershaft driving gear 5 is mounted on the inner ring of the countershaft driving gear 5. The outer ring of the countershaft driving gear 5 has a tooth profile, which meshes with the tooth profile of the inner ring of the countershaft driving gear 5. The output end of the countershaft power mechanism is fixed to the countershaft driving gear 5, and the countershaft power mechanism is a reduction motor 12. The reduction motor 12 drives the countershaft driving gear 5 to rotate, and the rotation of the countershaft driving gear 5 drives the countershaft driven gear 8 to rotate, thereby driving the pier bag connecting support plate 3 fixed to the countershaft driven gear 8 to rotate synchronously, thereby driving the synchronous rotation of the pier bag clamp 4 below.

[0027] like Figure 2 and Figure 3 As shown, an air duct 7 is provided on the hand-grip connecting plate 9. One end of the air duct 7 is connected to an external air source, and the other end points toward the inner side of the gear ring of the secondary shaft driven gear 8. A pier connection support plate 3 is fixed to the outer circumference of the secondary shaft driven gear 8, and four pier clamping claws 4 are fixed to the lower end of the pier connection support plate 3.

[0028] The pier bag connecting support plate 3 is a cylindrical structure with an inner cavity. The inner space of the gear ring of the secondary shaft driven gear 8 is connected to the inner cavity of the cylindrical structure. A vent hole 10 is provided at the bottom of the pier bag connecting support plate 3. In this embodiment, the pier bag clamping claw 4 is fixed to the bottom of the pier bag connecting support plate 3, and four pier bag clamping claws 4 are arranged around the vent hole 10. The top surface of the pier bag clamping claw 4 has an exhaust groove 11. One end of the exhaust groove 11 is connected to the vent hole 10, and the other end extends outward along the pier bag clamping claw 4 and points to the outer periphery of the pier bag. In this way, through the design of the exhaust groove 11, the final main conveying direction of the dust cleaning is the outer periphery of the pier bag, which can reduce the possibility of dust accumulation falling on the top of the pier bag and reduce the pollution to the pier bag. The dust accumulation that falls on the ground outside the pier bag is cleaned by cleaning machinery such as a sweeper, a vacuum cleaner, etc., which is not specifically explained in this embodiment.

[0029] In this embodiment, the inner ring of the secondary shaft driven gear 8, the inner cavity of the pier connection support plate 3, and the vent 10 cooperate to form an effective air path. In conjunction with the design of the air duct 7, when pressurized gas is introduced into the air duct 7 from an external air source, the pressurized gas can purge the teeth of the secondary shaft driven gear 8 and the secondary shaft driving gear 5, causing the dust and impurities on their surfaces to fall off and be discharged outward along the air path. This action does not require manual cleaning and can be automated. In actual air path design, a solenoid valve can be designed on the air duct 7 or the air source connected to it to control the on / off of the pressurized gas supply. Purging can preferably be performed during non-pier operation to reduce interference and contamination caused by the dust cleaning process to the pier operation below.

[0030] Furthermore, in this embodiment, the end of the air guide pipe 7 is connected to the air guide port 6 .

[0031] like Figure 4 As shown, the air guide 6 is a downward-slanting groove-shaped structure. One end of the groove is connected to the air guide pipe 7, and the other end is a through-hole pointing toward the lower end face of the inner ring of the countershaft driven gear 8. The top opening of the groove structure points toward the teeth of the countershaft driving gear 5. The configuration of the air guide 6 not only guides the pressurized air from the air guide pipe 7 downward through the groove structure, but also utilizes the top opening of the groove structure to direct part of the airflow toward the countershaft driving gear 5, which helps to clean dust accumulated on the surface teeth of the countershaft driving gear 5.

[0032] Furthermore, in this embodiment, a plurality of air guide holes are evenly spaced at the bottom of the groove structure of the guide air vent 6 in the direction corresponding to the inner ring of the secondary shaft driven gear 8. The air guide holes can be designed as oblong holes (13), and the oblong holes (13) are set corresponding to the tooth profile of the inner ring of the secondary shaft driven gear 8. When the tooth profile of the inner ring of the secondary shaft driven gear 8 is a straight tooth, the length direction of the oblong holes (13) is parallel to the tooth groove of the straight tooth, which facilitates the dust cleaning operation along the tooth groove of the secondary shaft transmission gear at the rear side of the guide air vent 6.

[0033] The self-cleaning pier bag hand grip designed in this way utilizes the space formed by the existing countershaft driven gear 8 and countershaft driving gear 5 in the pier bag hand grip, and cooperates with the pier bag connecting support plate 3 and the vent hole 10 to conveniently and quickly form a dust cleaning channel. In addition, combined with the introduction of pressurized gas, it can perform effective self-cleaning operations. This structural improvement can be modified and installed based on the existing pier bag hand grip. The modification is convenient and low-cost, and has good market prospects. It can be adapted to the pier bag process in automated operations, which can easily reduce manual dust cleaning operations and further improve the automation and continuity of transportation.

[0034] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
