Description

Technical Field

[0001] The invention relates to the technical field of logistics packaging equipment, and in particular to an automatic packaging device for particle material logistics transportation. Background Art

[0002] Rubber granules are a common plastic raw material, usually used to manufacture various plastic products. In the process of plastic granule production, workers are usually required to take the processed granules out of the container and pack the batches of granules into cans, barrels or bags for unified packaging. In the packaging process, corresponding transportation devices are generally used, and the corresponding discharging mechanism will be used to deliver the plastic granules to the transportation device.

[0003] Traditional pellet packaging equipment is usually driven by independent motors or cylinders, with a decentralized structure, poor synchronization, prone to timing disorders, long mechanical transmission chains, large cumulative errors, high maintenance costs, and weighing sensors that are easily disturbed by vibration.

[0022] The present invention provides an automatic packing device for the logistics transportation of granular materials, having the following beneficial effects:

[0023] 1. The present invention has an integrated design of compaction - material distribution - material pushing: The fan-shaped side pressure frame rotates periodically driven by the synchronous drive mechanism, applying a lateral pressure to the granular materials in the feeding hopper to ensure that the materials are tightly stacked, avoiding measurement errors caused by looseness. The L-shaped closed push plate is precisely and quantitatively linked by the beam frame to drive the L-shaped closed push plate to reciprocate. Each material pushing stroke is fixed, ensuring that the volume of the materials pushed out each time is the same. At the same time, when the push plate retracts, it closes the bottom of the feeding hopper to prevent the continuous falling of materials from interfering with the measurement. Multi-channel synchronous material distribution, the partition plate divides the guiding inclined platform into multiple equidistant channels, realizing multi-share synchronous sub-packaging under a single material pushing action, significantly improving the packing efficiency.

[0024] 2. The present invention has a mechanical synchronization ability without power dependence: The special-shaped gears uniformly control the compaction, material pushing, sealing, and filling actions through the linkage frame. All mechanisms strictly operate in coordination according to the phase and are synchronously opened. When retracting, they are sealed, without the need for electronic sensors or PLC control, and have strong anti-interference ability.

[0025] 3. The present invention has the ability of dynamic sealing to prevent cross-contamination: The opening and closing plate and the partition plate form an alternately opening and closing physical isolation, only opening the target channel during the material pushing stage, and keeping the other channels sealed, completely solving the problem of material mixing during multi-channel parallel operation. The sealing action is mechanically driven by the linkage fixed shaft, without vulnerable parts such as solenoid valves, having a long service life and requiring no maintenance.

[0026] 4. The present invention has a mechanical step driving ability: The internal disk and the internal gear disk achieve indexing and positioning through the elastic meshing of the embedded tooth blocks. Every time a material pushing action is completed, the extension frame two pushes the resisting arm to trigger a step feeding once, and the moving distance of the packaging appliance precisely matches the single material pushing amount.

The feeding and compressing mechanism 4 is arranged on the top of the fixed frame 1 and inside the top-mounted frame 2. The material distributing and guiding mechanism 5 is arranged on the fixed frame 1 and in the output direction of the feeding and compressing mechanism 4. The quantitative pushing mechanism 6 is arranged on one side of the top-mounted frame 2 away from the material distributing and guiding mechanism 5. The synchronous driving mechanism 7 is distributed on both sides inside the top-mounted frame 2 and between the material distributing and guiding mechanism 5 and the quantitative pushing mechanism 6. The linkage sealing mechanism 8 is arranged inside the top-mounted frame 2 and between the feeding and compressing mechanism 4 and the material distributing and guiding mechanism 5. The synchronous filling mechanism 9 is arranged on the internal platform 3. First of all, this device is mainly aimed at the filling and packing operation during the transportation of granular materials. The overall device structure is mainly fixed by the fixed frame 1, the top-mounted frame 2 and the internal platform 3 added to the fixed frame 1. The feeding and compressing mechanism 4 mainly responsible for the input of granular materials is installed on the top of the fixed frame 1. The material distributing and guiding mechanism 5 added to the fixed frame 1 distributes and conveys the granular logistics input into the feeding and compressing mechanism 4 through its own structure. When the synchronous driving mechanism 7 added to the top-mounted frame 2 is started, a reciprocating driving force will be generated, driving the quantitative pushing mechanism 6 adjacent to the feeding and compressing mechanism 4 to quantitatively push the logistics at the bottom of the feeding and compressing mechanism 4 into the material distributing and guiding mechanism 5. All actions are coordinated by the synchronous driving mechanism 7. With the drive of the synchronous driving mechanism 7, the self-structure of the feeding and compressing mechanism 4 will generate a downward pressure synchronously, driving the materials in the feeding and compressing mechanism 4 to be compacted, ensuring the quantitative conveying each time. The logistics guided by the material distributing and guiding mechanism 5 in portions is guided to the synchronous filling mechanism 9 added to the internal platform 3. The synchronous filling mechanism 9 itself can also follow the drive of the synchronous driving mechanism 7, so that the packages carrying the granules can be intermittently conveyed to the output part of the material distributing and guiding mechanism 5 to synchronously receive the quantitative granular logistics to be packed.

The second side push rods 83 installed at both ends of the linkage fixed shaft 82 are docked with the first extension rod 74. When the first extension rod 74 follows the linkage frame 72 to form a forward pushing state, it will synchronously push the second side push rods 83 to rotate, so that the linkage fixed shaft 82 and the opening and closing plates 84 rotate. At this time, the output hole structure of the feed hopper 41 facing the guiding inclined platform 51 can be driven to open.

When the first extension rod 74 retracts following the linkage frame 72, the opening and closing plate 84 will rotate following the linkage fixed shaft 82 and re-close the output hole structure of the feeding hopper 41, so that new granular logistics can gather at the bottom of the feeding hopper 41. The logistics quantitatively output in batches along multiple channel structures at the top of the guiding inclined table 51 will be guided to the synchronous filling mechanism 9 along the guiding table 54. The multi-station table 91 included in the synchronous filling mechanism 9 is fixed on the built-in table 3 and is suspended below the material distribution guiding mechanism 5. Multiple output pulley assemblies 92 corresponding to the channel structures of the guiding inclined table 51 are installed on the multi-station table 91. The packages to be carried and packed are placed on the output pulley assemblies 92 by using the special-shaped bases installed on the belt ends of the output pulley assemblies 92. The output shafts of the multiple output pulley assemblies 92 are connected to each other, so that the output pulley assemblies 92 can synchronously convey the packages. The intermittent traction assembly included in the synchronous filling mechanism 9 is installed in the output shaft area of the output pulley assemblies 92. The internal gear disk 93 included in the intermittent traction assembly is statically fixed on the multi-station table 91, and the internally rotating internal disk 94 is installed on the output shaft of the output pulley assembly 92. The sleeve structure of the internal disk 94 is fixed on the output shaft of the output pulley assembly 92. With the displacement of the second extension frame 66, the installed clamping shaft structure will push the contact arm 97 and the positioning rod 96, thereby driving the output shafts of the multiple output pulley assemblies 92 to rotate, and at the same time starting the synchronous intermittent conveying of the output pulley assemblies 92 to drive the packages to follow up in real time.While the built-in disk 94 rotates inside the internal gear disk 93 at the same time, so that the embedded tooth blocks 95 installed on the outer ring part of the built-in disk 94 can be fitted into the inner tooth key grooves of the internal gear disk 93 in real time, and real-time locking is achieved through the snap ring structure between the embedded tooth blocks 95 and the built-in disk 94. When the second extension frame 66 retracts due to reciprocating displacement and contacts the abutting arm 97, it will drive the abutting arm 97 to rotate along the positioning rod 96, thereby preventing the second extension frame 66 from driving the output pulley assembly 92 to work in the reverse direction. After the second extension frame 66 disengages from the abutting arm 97, the abutting arm 97 will rebound due to the snap ring structure installed between it and the positioning rod 96 for the next push.,

[0050] Working principle: First of all, this device is mainly for the filling and packing operation during the transportation of granular materials. The overall structure of the device is mainly fixed by the fixed frame 1, the overhead frame 2 added to the fixed frame 1 and the built-in table 3. The feeding and compaction mechanism 4 mainly responsible for the input of granular materials is installed on the top of the fixed frame 1. The material distribution and guiding mechanism 5 added to the fixed frame 1 distributes and conveys the granular material flow input into the feeding and compaction mechanism 4 according to its own structure. When the synchronous drive mechanism 7 added to the overhead frame 2 is started, a reciprocating driving force will be generated, driving the quantitative pusher mechanism 6 arranged adjacent to the feeding and compaction mechanism 4 to quantitatively push the material flow at the bottom of the feeding and compaction mechanism 4 into the material distribution and guiding mechanism 5. All actions are coordinated by the synchronous drive mechanism 7. With the drive of the synchronous drive mechanism 7, the self-structure of the feeding and compaction mechanism 4 will generate a downward pressure synchronously, driving the material in the feeding and compaction mechanism 4 to be compacted to ensure each quantitative conveying. The material flow guided by the material distribution and guiding mechanism 5 in portions is guided to the synchronous filling mechanism 9 added to the built-in table 3. The synchronous filling mechanism 9 itself can also follow the drive of the synchronous drive mechanism 7, so that the packages carrying granules can be intermittently conveyed to the output part of the material distribution and guiding mechanism 5 to synchronously receive the quantitative granular material flow to be packed. The feeding hopper 41 included in the feeding and compaction mechanism 4 is installed and fixed on the top of the fixed frame 1. The output hole structure with both sides open at the bottom is respectively connected to the material distribution and guiding mechanism 5 and the quantitative pusher mechanism 6. The hopper-shaped structure at the top of the feeding hopper 41 can expand the area of material input, so that the granular material flow can be quickly docked inside the feeding hopper 41. The rotatable fan-shaped side pressure frame 42 on the feeding hopper 41 is connected to the synchronous drive mechanism 7 through the side push rods 43 added to both ends of its rotating shaft. When the synchronous drive mechanism 7 generates a reciprocating traction force, the generated reciprocating driving force will drive the side push rods 43 to rotate, so that the fan-shaped side pressure frame 42 rotates inside the feeding hopper 41 following the side push rods 43, synchronously driving the material flow inside the feeding hopper 41 to be pressed and compacted. The guiding inclined platform 51 included in the material distribution and guiding mechanism 5 is suspended and installed on the fixed frame 1 through the damping feet 52 added to the side walls. At the same time, using the damping property of the damping feet 52, the guiding inclined platform 51 can swing up and down on the top of the fixed frame 1. The partition plates 53 distributed on the guiding inclined platform 51 form a plurality of equidistant channel structures. At the same time, the input ports of all channel structures are attached to the output hole structure of the feeding hopper 41. The plurality of channel structures formed by the partition plates 53 can quantitatively convey the granular material flow at the same time, and then quantitatively guided to the synchronous filling mechanism 9 by the plurality of guiding hopper structures added to the guiding platform 54. The contact rack 55 added to the bottom of the guiding inclined platform 51 is in contact with the structure of the quantitative pusher mechanism 6 at the same time. As the quantitative pusher mechanism 6 reciprocates along with the synchronous drive mechanism 7, the contact rack 55 will drive the guiding inclined platform 51 to swing up and down along the damping feet 52, and use the generated swing traction force to increase the speed of guiding the material discharge of the guiding inclined platform 51.The positioning rail frame 62 included in the quantitative pushing mechanism 6 is distributed and installed inside the top frame 2 and is located on the other side of the feed hopper 41, so that the linkage beam frame 61 included in the quantitative pushing mechanism 6 is displaced inside the top frame 2 along the positioning rail frame 62 through the pulley structures on both sides, and the guide bent rod 64 installed on the side wall of the positioning rail frame 62 is connected to the structure of the synchronous driving mechanism 7, and the reciprocating traction force formed will drive the guide bent rod 64 to drive the linkage beam frame 61 to move back and forth along the positioning rail frame 62, and the L-shaped closed push plate 63 installed on the linkage beam frame 61 is pulled into the interior of the feed hopper 41, and its L-shaped structure will push the logistics at the bottom of the feed hopper 41 onto the guiding inclined platform 51, and the amount of logistics sent out is determined according to the active volume of the L-shaped closed push plate 63. The linkage beam 61 is fixed to the original position, and the extension frame 65 installed on the linkage beam 61 can contact the abutment rack 55 installed on the bottom of the guide ramp 51 through the rack structure at the bottom. When the extension frame 65 follows the linkage beam 61 to move back and forth, the rack structure of the extension frame 65 drives the guide ramp 51 to swing up and down along the damping foot frame 52. The extension frame 2 66 installed on the linkage beam 61 also follows the linkage beam 61 to move back and forth, and drives the intermittent traction component included in the synchronous filling mechanism 9 to operate, so that the synchronous filling mechanism 9 can follow the rate of each thrust and intermittently feed the packaged objects to be carried, and serve as the synchronous driving mechanism for the coordinated operation of all actions. The side frames 71 included in the synchronous drive mechanism 7 are relatively distributed in the top frame 2 on both sides. The side frames 71 included in the synchronous drive mechanism 7 are fixed on the inner wall of the top frame 2, while limiting the reciprocating movement of the linkage frame 72 on the linkage frame 72. The linkage frame 72 is provided with a tooth key structure opposite to the upper and lower parts. When the output motor inside the side frame 71 drives the special-shaped gear 73 to rotate, its fan-shaped tooth key structure will reciprocate and contact the tooth key structure distributed up and down inside the linkage frame 72, so that the linkage frame 72 reciprocates along the side frames 71. The fan-shaped tooth keys of the special-shaped gear 73 control the reciprocating rhythm of the linkage frame 72. When the linkage frame 72 moves back and forth, it will drive the linkage beam frame 61 to reciprocate through the guide crank rod 64 fixed at one end, and the linkage frame 72 is fixed at the other end. The extension rod 2 75 will pull the side push rod 1 43 to rotate, so as to drive the fan-shaped side pressure frame 42 to rotate and compact synchronously, and the extension rod 1 74 installed on the linkage frame 72 will synchronously drive the linkage sealing mechanism 8 to operate on the feed hopper 41. The suspension frame 81 included in the linkage sealing mechanism 8 is fixed in the top frame 2, and the linkage fixed shaft 82 installed on the suspension frame 81 and the multiple groups of opening and closing plates 84 fixed on the linkage fixed shaft 82 are in contact with the side wall of the feed hopper 41 in the direction of the material distribution guide mechanism 5, and the opening and closing plates 84 are attached to the output hole structure of the feed hopper 41 along the channel structure of the partition plate 53, and the side push rods 2 83 installed at both ends of the linkage fixed shaft 82 are connected to the extension rod 1 74. When the extension rod 1 74 follows the linkage frame 72 to form a pushing forward state,It will synchronously drive the rotation of the side push rod two 83, thereby causing the linkage fixed shaft 82 and the opening and closing plate 84 to rotate. At this time, it can drive the output hole structure of the feeding hopper 41 facing the guiding inclined platform 51 to open, so that the quantitative feeding mechanism 6 operating synchronously can quantitatively push the logistics into the multiple channel structures of the guiding inclined platform 51 in batches at the same time. When the first extension rod 74 retracts following the linkage frame 72, the opening and closing plate 84 will rotate following the linkage fixed shaft 82 and re-close the output hole structure of the feeding hopper 41, so that new granular logistics will gather at the bottom of the feeding hopper 41. The logistics quantitatively output in batches along the multiple channel structures at the top of the guiding inclined platform 51 will be guided to the synchronous filling mechanism 9 along the guiding platform 54. The multi-station platform 91 included in the synchronous filling mechanism 9 is fixed on the built-in platform 3 and suspended below the material distribution guiding mechanism 5. Multiple output pulley assemblies 92 corresponding to the channel structures of the guiding inclined platform 51 are installed on the multi-station platform 91. The packages to be carried and packed are placed on the output pulley assemblies 92 by using the special-shaped bases installed at the belt ends of the output pulley assemblies 92. The output shafts of the multiple output pulley assemblies 92 are connected to each other, so that the output pulley assemblies 92 can synchronously convey the packages. The intermittent traction assembly included in the synchronous filling mechanism 9 is installed in the area of the output shafts of the output pulley assemblies 92. The internal gear disc 93 included in the intermittent traction assembly is statically fixed on the multi-station platform 91, and the internal disc 94 rotating inside it is installed on the output shaft of the output pulley assembly 92. The sleeve structure of the internal disc 94 is fixed on the output shaft of the output pulley assembly 92. As the second extension frame 66 displaces, the installed clamping shaft structure will push the contact arm 97 and the positioning rod 96, thereby driving the output shafts of the multiple output pulley assemblies 92 to rotate, and at the same time starting the synchronous intermittent conveying of the output pulley assemblies 92 to drive the packages to follow in real time. At the same time, the internal disc 94 rotates inside the internal gear disc 93, so that the embedded tooth blocks 95 installed on the outer ring part of the internal disc 94 can be fitted into the inner tooth key grooves of the internal gear disc 93 in real time, and real-time locking is achieved through the snap spring structure between the embedded tooth blocks 95 and the internal disc 94. When the second extension frame 66 retracts due to reciprocating displacement and contacts the contact arm 97, it will drive the contact arm 97 to rotate along the positioning rod 96, so as to prevent the second extension frame 66 from driving the output pulley assembly 92 to work in the reverse direction. After the second extension frame 66 disengages from the contact arm 97, the contact arm 97 will rebound due to the snap spring structure installed between it and the positioning rod 96 for the next round of pushing.
