A resin-recycled salt brick molding, conveying, and packaging device

Abstract

This invention relates to the field of conveying and packaging technology, and provides a resin recycled salt brick molding, conveying, and packaging device, including a packaging component, a conveying component disposed on one side of the packaging component, and a molding production line. A bagging component and a sealing component are respectively disposed on one side of the packaging component. This device solves the problems of salt bricks being easily trapped between the baffle and the conveyor belt and crushed due to compression when the baffle blocks subsequent materials, and the problem of uncompressed salt bricks being displaced and colliding with each other. The device uses a blocking component, which achieves blocking and release of salt bricks by the up-and-down swing of a bucket-shaped blocking box. During blocking, the auxiliary conveyor belt continues to run, and the salt bricks can fall into the blocking box successively. This achieves the blocking purpose, and because there is a gap between the blocking box and the conveyor belt and the blocking method is a surrounding lifting type, it prevents the salt bricks from being trapped and crushed. At the same time, the lifting of the blocking box does not forcibly move the salt bricks, reducing the possibility of them colliding with each other due to displacement.

Description

Technical Field

[0001] This invention relates to the field of conveying and packaging technology, and more specifically, to a resin-recycled salt brick forming conveying and packaging device. Background Technology

[0002] Resin regeneration salt bricks are specialized salt products used for resin regeneration in water softening equipment. They are typically made from high-purity sodium chloride through a pressing process into blocks. Their main function is to remove calcium and magnesium ions from the water through ion exchange reactions, restoring the resin's softening ability. They are widely used in household water softeners, industrial water treatment systems, and other fields. Compared to traditional granular salt, salt bricks have advantages such as high purity, uniform dissolution, resistance to clumping, and long service life, effectively improving resin regeneration efficiency and reducing equipment maintenance costs.

[0003] Currently, when resin recycled salt bricks are molded and packaged, high-purity raw materials are first pressed into blocks using molding and briquetting equipment. Then, the pressed salt bricks fall onto a conveyor belt, which smoothly transports the salt bricks. Once the blocks are transported to the corresponding position in the packaging bag, the automatic filling is completed by natural bag drop.

[0004] However, during the conveying process, in order to achieve quantitative operation, when the salt bricks reach the set amount, the conveyor belt will stop running and the baffle will be quickly moved to block the subsequent material. This design can easily cause some salt bricks to be trapped between the baffle and the conveyor belt and break under the pressure; while the salt bricks that are not squeezed will be moved by the baffle and thus cause them to collide with each other. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a resin recycled salt brick molding, conveying and packaging device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a resin recycled salt brick molding, conveying and packaging device, comprising a packaging component, a conveying component disposed on one side of the packaging component and a molding production line, wherein the conveying component is located between the packaging component and the molding production line, and a bagging component and a sealing component are respectively disposed on one side of the packaging component.

[0007] The packaging assembly includes a frame and a hopper disposed on top of the frame, and a packaging conveyor belt mechanism disposed at the bottom of the frame.

[0008] The conveying assembly includes an auxiliary conveyor belt mechanism on one side of the frame, two baffles symmetrically installed on the top of the auxiliary conveyor belt mechanism, one end of the auxiliary conveyor belt mechanism extending above the hopper, and an inclined hopper at the other end of the auxiliary conveyor belt mechanism.

[0009] The auxiliary conveyor belt mechanism is equipped with a blocking component near the hopper. The blocking component includes two connecting plates hinged to the side wall of the auxiliary conveyor belt mechanism, and a blocking box is connected between the two connecting plates.

[0010] The invention is further configured such that: the inclined hopper is connected to the molding production line; a gap is provided between the blocking box and the auxiliary conveyor belt mechanism; the blocking assembly also includes a mounting frame installed on one side of the auxiliary conveyor belt mechanism; a servo motor is installed on one side of the mounting frame; the output end of the servo motor is connected to one of the connecting plates; the inner side wall of the blocking box is provided with an inclined portion; two buffer mechanisms are installed on the outer side wall of the blocking box; one end of each of the two buffer mechanisms is connected to a bearing plate; and multiple spring plates are equidistantly connected to the side of the bearing plate away from the buffer mechanism.

[0011] The invention is further configured such that: both buffer mechanisms include a fixed plate connected to the blocking box, the side wall of the fixed plate is hinged with two hinge plates, a connecting block is hinged between the ends of the two hinge plates away from the fixed plate, the connecting block is connected to the bearing plate, and a spring rod is hinged between one of the hinge plates and the corresponding fixed plate.

[0012] By adopting the above technical solution, the blocking component achieves the blocking and release of salt bricks through the up-and-down swing of the bucket-shaped blocking box. During the blocking process, the auxiliary conveyor belt mechanism continues to operate, and the salt bricks can fall into the blocking box one after another. This achieves the blocking purpose, and because there is a gap between the blocking box and the conveyor belt and the blocking method of lifting around, it avoids the salt bricks being clamped and broken. At the same time, the lifting action of the blocking box will not force the salt bricks to move, reducing the phenomenon of salt bricks colliding with each other due to displacement. When the blocking box swings downward, the salt bricks inside can slide smoothly down along the inclined part. The whole process does not affect the forming and conveying of salt bricks, effectively solving the salt brick breakage and collision problems existing in the original baffle design.

[0013] By installing two buffer mechanisms and a bearing plate with spring plates on the outer wall of the blocking box, when the salt brick slides from the blocking box or falls from the auxiliary conveyor belt, the spring plate can use its own elasticity to provide initial buffering for the salt brick. At the same time, the bearing plate swings downward under the impact of the salt brick, causing the hinge plate of the buffer mechanism to swing and pull the spring rod, thereby achieving secondary buffering and force relief. This allows the spring plate to move down a certain distance with the salt brick, reducing the chance of the salt brick bouncing up, reducing the falling height of the salt brick and the collision breakage rate, and improving the yield rate.

[0014] The present invention is further configured such that: the bagging assembly includes a first adsorption mechanism and a second adsorption mechanism disposed below the frame, and the first adsorption mechanism and the second adsorption mechanism are respectively disposed on both sides of the packaging conveyor belt mechanism.

[0015] The present invention is further configured such that: the first adsorption mechanism includes a first support frame disposed on one side of the packaging conveyor belt mechanism and a lifting platform slidably connected to the side wall of the first support frame; a swing plate is hinged to the bottom of the lifting platform; a first adjusting cylinder is installed at the bottom of the swing plate; a second adjusting cylinder is installed horizontally with the piston rod end of the first adjusting cylinder vertically upward through the swing plate; and a first suction cup assembly is installed at the piston rod end of the second adjusting cylinder.

[0016] The present invention is further configured such that: two lifting cylinders are symmetrically installed on the side wall of the first support frame, both of the lifting cylinders are connected to the lifting platform, an auxiliary motor is installed at the bottom of the lifting platform, and the output end of the auxiliary motor is connected to the swing plate.

[0017] The present invention is further configured such that: the second adsorption mechanism includes a second support frame disposed on the side of the packaging conveyor belt mechanism away from the first adsorption mechanism, a fourth adjusting cylinder is installed on the top of the second support frame, a second suction cup group is installed at the piston rod end of the fourth adjusting cylinder, the second suction cup group is disposed opposite to the first suction cup group, and two sorting mechanisms are symmetrically installed on the side wall of the second suction cup group.

[0018] The present invention is further configured such that: each of the two sets of sorting mechanisms includes a telescopic cylinder installed on the side wall of the second suction cup group, the piston rods of the two telescopic cylinders are arranged opposite to each other, the end of the piston rod of the telescopic cylinder is connected to an L-shaped plate, the top of the L-shaped plate is equipped with a fifth adjusting cylinder, the end of the piston rod of the fifth adjusting cylinder passes through the L-shaped plate and is connected to an electric gripper, and the two electric grippers are arranged opposite to each other.

[0019] The invention is further configured such that: a drive motor is installed on the top of the second support frame, the output end of the drive motor extends into the interior of the second support frame and is vertically connected to a lead screw, a sliding plate is threaded to the outer wall of the lead screw, a support plate is slidably connected to the top of the sliding plate, the support plate is U-shaped, a third adjusting cylinder is installed on the top of the sliding plate, a through groove is opened on the side wall of the second support frame, the third adjusting cylinder is disposed through the through groove, and the piston rod end of the third adjusting cylinder is connected to the support plate.

[0020] By adopting the above technical solution, through the cooperation of the telescopic cylinder, the fifth adjusting cylinder and the electric gripper, the bottom corner of the packaging bag can be grasped and its height adjusted, so as to reduce the height difference of the salt brick falling into the packaging bag. At the same time, the bottom position of the packaging bag is gradually adjusted according to the falling material during the salt brick falling process. Combined with the buffer of the blocking component, the breakage rate of the salt brick is further reduced.

[0021] By setting up a pallet, the pallet can move upward under the drive of the motor and lead screw to support the bottom of the packaging bag. The cushioning sponge pad on top can cushion the falling salt bricks, and the pallet can provide support for the packaging bag, preventing the packaging bag from separating from the suction cup assembly due to the impact of falling salt bricks, thus ensuring the stability of the packaging process and indirectly reducing the possibility of salt bricks colliding and breaking due to unstable packaging.

[0022] The invention is further configured such that: the sealing assembly includes a gantry frame, the packaging conveyor belt mechanism passes through the interior of the gantry frame, a connecting column is vertically connected downward to the top wall of the interior of the gantry frame, a fixed platform is installed at the bottom of the connecting column, two hinged arms are symmetrically hinged to both sides of the fixed platform, a sealing cylinder is hinged between the tops of the two hinged arms, and a heat sealing head is installed at the bottom of each of the two hinged arms, with the two heat sealing heads arranged opposite to each other.

[0023] By adopting the above technical solution, when the packaging bag moves to the bottom of the sealing assembly, the opening of the packaging bag moves between the two heat sealing heads. Then, the sealing cylinder extends and the two hinged arms swing, causing the two heat sealing heads to come closer to each other to clamp and heat seal the opening of the packaging bag. After the heat sealing is completed, the two heat sealing heads separate from each other, and then the packaging conveyor belt mechanism continues to transport the material.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] (1) By setting up a blocking component, the blocking component can block and release the salt bricks by swinging the bucket-shaped blocking box up and down. During the blocking process, the auxiliary conveyor belt mechanism keeps running, and the salt bricks can fall into the blocking box one after another. This not only achieves the blocking purpose, but also avoids the situation where the salt bricks are clamped and broken because there is a gap between the blocking box and the conveyor belt and the blocking method of lifting around is adopted. At the same time, the lifting action of the blocking box will not force the salt bricks to move, reducing the phenomenon of salt bricks colliding with each other due to displacement. When the blocking box swings down, the salt bricks inside can slide smoothly along the inclined part. The whole process does not affect the forming and conveying of the salt bricks, effectively solving the problem of salt brick breakage and collision in the original baffle design.

[0026] (2) By setting two buffer mechanisms and a bearing plate with spring plates on the outer wall of the blocking box, when the salt brick slides from the blocking box or falls from the auxiliary conveyor belt, the spring plate can use its own elasticity to buffer the salt brick initially. At the same time, the bearing plate swings downward under the impact of the salt brick, which drives the hinge plate of the buffer mechanism to swing and pull the spring rod to achieve secondary buffering and unloading. This allows the spring plate to move down a certain distance with the salt brick, reducing the situation where the salt brick is bounced up, reducing the falling height of the salt brick and the collision breakage rate, and improving the yield rate.

[0027] (3) By setting up a sorting mechanism, the bottom corner of the packaging bag can be grabbed and its height adjusted by the cooperation of the telescopic cylinder, the fifth adjusting cylinder and the electric gripper, so that the height difference of the salt brick falling into the packaging bag is reduced. At the same time, the bottom position of the packaging bag is gradually adjusted according to the material falling during the salt brick falling process. Combined with the buffer of the blocking component, the breakage rate of the salt brick is further reduced.

[0028] (4) By setting up a tray, the tray can move upward and support the bottom of the packaging bag under the drive of the drive motor and the lead screw. The buffer sponge pad on top can buffer the falling salt bricks, and the tray can provide support for the packaging bag, avoiding the impact of the falling salt bricks causing the packaging bag to separate from the suction cup group, ensuring the stability of the packaging process, and indirectly reducing the situation of salt bricks being broken due to unstable packaging.

[0050] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0051] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0052] Please see Figures 1-13 The present invention provides the following technical solutions:

[0053] Example 1, see Figure 1 and Figure 13 A resin recycled salt brick molding, conveying and packaging device includes a packaging component 1, a conveying component 2 disposed on one side of the packaging component 1 and a molding production line. The conveying component 2 is located between the packaging component 1 and the molding production line. The molding production line is a powder briquetting machine. The resin recycled salt brick raw material is first briquetized by the molding production line and then conveyed by the conveying component 2. The molded salt brick is then bagged by the packaging component 1.

[0054] See Figure 1 and Figure 6 The specific structure of packaging component 1 is as follows:

[0055] The packaging component 1 includes a frame 11 and a hopper 12 disposed on top of the frame 11. A packaging conveyor belt mechanism 13 is disposed at the bottom of the frame 11. The frame 11 is used to support the hopper 12. The hopper 12 is used to carry and discharge the salt bricks conveyed by the conveyor component 2. The packaging bag for packaging the salt bricks is conveyed by the packaging conveyor belt mechanism 13, causing the packaging bag to be transferred to the bottom of the hopper 12. The salt bricks inside the hopper 12 fall into the packaging bag below, and then are sent out by the packaging conveyor belt mechanism 13.

[0056] See Figure 1 and Figure 2 The specific structure of the conveying component 2 is as follows:

[0057] The conveying assembly 2 includes an auxiliary conveyor belt mechanism 22 on one side of the frame 11. Two baffles 23 are symmetrically installed on the top of the auxiliary conveyor belt mechanism 22. One end of the auxiliary conveyor belt mechanism 22 extends above the hopper 12, and the other end of the auxiliary conveyor belt mechanism 22 is provided with an inclined hopper 21. The inclined hopper 21 is used to connect with the molding production line. The salt bricks formed in the molding production line slide to the top of the auxiliary conveyor belt mechanism 22 via the inclined hopper 21. The auxiliary conveyor belt mechanism 22 conveys the slid-out salt bricks horizontally towards the hopper 12. During this process, the two baffles 23 cooperate to guide the salt bricks, so that the salt bricks can be conveyed in a predetermined direction. When the salt bricks are conveyed to the top of the hopper 12, they fall into the hopper 12 due to gravity and are then bagged using packaging bags.

[0058] See Figure 1 The packaging component 1 has a bagging component 4 and a sealing component 5 on one side. The bagging component 4 is used to convey and support the packaging bags, which facilitates the subsequent bagging operation. The bagged packaging bags are horizontally conveyed to the sealing component 5 by the packaging conveyor belt mechanism 13. Then, the sealing component 5 seals the packaging bags. The specific structure of the bagging component 4 is as follows:

[0059] See Figure 1 and Figure 8The bagging assembly 4 includes a first adsorption mechanism 41 and a second adsorption mechanism 42 disposed below the frame 11. The first adsorption mechanism 41 and the second adsorption mechanism 42 are respectively disposed on both sides of the packaging conveyor belt mechanism 13. When the packaging bag needs to be opened, the packaging conveyor belt mechanism 13 firstly transports the empty packaging bag horizontally, with the opening of the empty packaging bag facing the second adsorption mechanism 42. When the packaging bag moves between the first adsorption mechanism 41 and the second adsorption mechanism 42, the first adsorption mechanism 41 adsorbs and grabs the packaging bag, causing the packaging bag to be lifted. Then, the first adsorption mechanism 41 and the second adsorption mechanism 42 work together to open the packaging bag. The opening of the opened packaging bag faces the discharge port at the bottom of the discharge hopper 12. The salt bricks that fall into the discharge hopper 12 continue to fall into the packaging bag. After the packaging bag is filled, the auxiliary conveyor belt mechanism 22 stops transporting, the salt bricks stop falling, and the fully loaded packaging bag is horizontally transported to the sealing assembly 5 by the packaging conveyor belt mechanism 13 for sealing.

[0060] See Figure 9 , Figure 10 and Figure 12 The first adsorption mechanism 41 includes a first support frame 411 disposed on one side of the packaging conveyor belt mechanism 13 and a lifting platform 413 slidably connected to the side wall of the first support frame 411. Two lifting cylinders 412 are symmetrically installed on the side wall of the first support frame 411, and both lifting cylinders 412 are connected to the lifting platform 413. The lifting cylinders 412 are used to push the lifting platform 413 to adjust its height along the vertical direction of the first support frame 411. A swing plate 414 is hinged to the bottom of the lifting platform 413, and an auxiliary motor 418 is installed at the bottom of the lifting platform 413. The output end of the auxiliary motor 418 is connected to the swing plate 414. The lifting platform 413 adjusts... During the process, the swing plate 414 moves up and down simultaneously. The auxiliary motor 418 drives the swing plate 414 to swing. A first adjusting cylinder 415 is installed at the bottom of the swing plate 414. During the swing, the swing plate 414 drives the first adjusting cylinder 415 to swing and adjust the angle. The piston rod end of the first adjusting cylinder 415 passes vertically upward through the swing plate 414 and a second adjusting cylinder 416 is installed horizontally. A first suction cup assembly 417 is installed at the piston rod end of the second adjusting cylinder 416. The first adjusting cylinder 415 and the second adjusting cylinder 416 work together to adjust the position of the first suction cup assembly 417, thereby facilitating the first suction cup assembly 417 to adsorb the packaging bag.

[0061] Specifically, firstly, the packaging bag is laid flat on the top surface of the packaging conveyor belt mechanism 13. The packaging conveyor belt mechanism 13 horizontally transports the empty packaging bag, with the opening of the empty packaging bag facing the second adsorption mechanism 42. When the packaging bag moves between the first adsorption mechanism 41 and the second adsorption mechanism 42, the lifting cylinder 412 pushes the lifting platform 413, the swing plate 414, the first adjusting cylinder 415, the second adjusting cylinder 416, and the first suction cup group 417 to move downward as a whole. Then, the auxiliary motor 418 drives the swing plate 414 to swing downward to a vertically downward state. At this time, the first suction cup group 417 is set downward. Then, the first adjusting cylinder 415 adjusts the position of the second adjusting cylinder 416 and the first suction cup group 417, so that the first suction cup group 417 can move above the opening of the flat packaging bag. Then, the second adjusting cylinder 416 pushes the first suction cup group 417 closer to the packaging bag, so that the first suction cup group 417 adsorbs the packaging bag.

[0062] Then, the lifting cylinder 412 pushes the lifting platform 413 and other components to rise and reset, and as... Figure 10 As shown, the swing plate 414 swings back to the horizontal state, and the first adjusting cylinder 415 and the second adjusting cylinder 416 retract and reset. At this time, the packaging bag adsorbed by the first suction cup group 417 is in a drooping state. In this state, the second adsorption mechanism 42 moves closer to the packaging bag, thereby opening the packaging bag.

[0063] See Figures 9-11 The specific structure of the second adsorption mechanism 42 is as follows:

[0064] The second adsorption mechanism 42 includes a second support frame 421 disposed on the side of the packaging conveyor belt mechanism 13 away from the first adsorption mechanism 41. A fourth adjusting cylinder 427 is installed on the top of the second support frame 421. A second suction cup assembly 429 is installed at the piston rod end of the fourth adjusting cylinder 427. The second suction cup assembly 429 is disposed opposite to the first suction cup assembly 417. The fourth adjusting cylinder 427 is used to push the second suction cup assembly 429 to a horizontal displacement, so that the second suction cup assembly 429 cooperates with the first suction cup assembly 417 to adsorb the packaging bag.

[0065] Specifically, when the first suction cup group 417 adsorbs the packaging bag and the packaging bag is in a drooping state, the fourth adjusting cylinder 427 pushes the second suction cup group 429 closer to the packaging bag. At this time, the two sides of the packaging bag are adsorbed by the first suction cup group 417 and the second suction cup group 429 respectively. After the packaging bag is adsorbed, the second adjusting cylinder 416 and the fourth adjusting cylinder 427 retract simultaneously, and the first suction cup group 417 and the second suction cup group 429 separate from each other, causing the opening of the packaging bag to be opened. The opening of the packaging bag is directly below the hopper 12. The salt brick falls into the packaging bag after falling through the hopper 12 for bagging. After bagging, the first suction cup group 417 and the second suction cup group 429 release the packaging bag. The packaging bag is sealed by the horizontal conveyor belt sealing component 5 of the packaging conveyor belt mechanism 13. The empty packaging bag continues to be conveyed by the packaging conveyor belt mechanism 13 and is supported by the bagging component 4 to facilitate subsequent bagging operations.

[0066] See Figure 7 The sealing assembly 5 includes a gantry frame 51, and a packaging conveyor belt mechanism 13 passes through the interior of the gantry frame 51. A connecting column 52 is vertically connected to the top wall of the interior of the gantry frame 51. A fixed platform 53 is installed at the bottom of the connecting column 52. Two hinged arms 54 are symmetrically hinged on both sides of the fixed platform 53. A sealing cylinder 56 is hinged between the tops of the two hinged arms 54. A heat sealing head 55 is installed at the bottom of each of the two hinged arms 54. The two heat sealing heads 55 are arranged opposite to each other. The heat sealing head 55 is composed of a metal head and an electric heating tube. The electric heating tube is embedded inside the metal head. The electric heating tube converts electrical energy into heat energy and transfers the heat to the metal head. When sealing is required, the opening of the packaging bag only needs to be moved between the two heat sealing heads 55. Then, the two heat sealing heads 55 move closer to each other to clamp and heat seal the opening of the packaging bag.

[0067] Specifically, when the packaging bag moves below the sealing assembly 5, the opening of the packaging bag moves between the two heat sealing heads 55. Then, the sealing cylinder 56 extends and the two hinged arms 54 swing, causing the two heat sealing heads 55 to come closer to each other and clamp and heat seal the opening of the packaging bag. After the heat sealing is completed, the two heat sealing heads 55 separate from each other, and then the packaging conveyor belt mechanism 13 continues to transport and unload the material.

[0068] In Example 2, during the conveying process, in order to achieve quantitative operation, a baffle is generally set at the end of the auxiliary conveyor belt mechanism 22. When the salt bricks reach the set amount, the auxiliary conveyor belt mechanism 22 will stop operating. At the same time, the baffle will be quickly moved to block the material on the auxiliary conveyor belt mechanism 22, thus blocking the subsequent material. Although the quantitative effect is achieved, this design is prone to causing some salt bricks to be sandwiched between the baffle and the conveyor belt and break under the squeezing action. The salt bricks that are not squeezed will be moved by the baffle and thus cause them to collide with each other.

[0069] See Figure 1 A blocking component 3 is installed at one end of the auxiliary conveyor belt mechanism 22 near the hopper 12. The blocking component 3 is used to block the salt bricks conveyed by the auxiliary conveyor belt mechanism 22. During the blocking process, the auxiliary conveyor belt mechanism 22 will not stop running, and the salt bricks will not be clamped and broken or moved and collide with each other.

[0070] See Figures 2-5 The specific structure of the blocking component 3 is as follows:

[0071] The blocking assembly 3 includes two connecting plates 31 hinged to the side wall of the auxiliary conveyor belt mechanism 22. A blocking box 32 is connected between the two connecting plates 31. The blocking box 32 is bucket-shaped and has an inclined portion on its inner side wall. There is a gap between the blocking box 32 and the auxiliary conveyor belt mechanism 22. When the blocking box 32 swings upward, it can block the salt bricks conveyed by the auxiliary conveyor belt mechanism 22. As the auxiliary conveyor belt mechanism 22 continues to run, the salt bricks will fall into the blocking box 32 one after another. This not only achieves the purpose of blocking the salt bricks but also prevents the salt bricks from being clamped. When the blocking box 32 swings downward, the salt bricks inside the blocking box 32 can slide down along the inclined portion. At the same time, the auxiliary conveyor belt mechanism 22 continues to run, and the salt bricks on the auxiliary conveyor belt mechanism 22 continue to fall. When the amount of salt bricks in the packaging bag reaches the required level, the blocking box 32 swings upward to continue blocking, and the packaging bag proceeds to the next sealing operation.

[0072] See Figures 2-5 The blocking assembly 3 also includes a mounting bracket 36 installed on one side of the auxiliary conveyor belt mechanism 22. A servo motor 35 is installed on one side of the mounting bracket 36. The output end of the servo motor 35 is connected to one of the connecting plates 31. The servo motor 35 is used to drive one of the connecting plates 31 to swing. The two connecting plates 31 and the blocking box 32 are connected to each other. Therefore, when one of the connecting plates 31 swings, the other connecting plate 31 and the blocking box 32 will swing synchronously.

[0073] Specifically, when the auxiliary conveyor belt mechanism 22 continuously conveys salt bricks, the blocking box 32 will swing around from the bottom of the auxiliary conveyor belt mechanism 22, causing the blocking box 32 to be lifted from bottom to top along the outer wall of the auxiliary conveyor belt mechanism 22. At this time, the salt bricks on the auxiliary conveyor belt mechanism 22 will be blocked by the blocking box 32. Moreover, the blocking method is not to press directly from top to bottom onto the surface of the auxiliary conveyor belt mechanism 22 as in the prior art, but to lift around from bottom to top, ensuring that the salt bricks will not be clamped and broken. Furthermore, the lifting action of the salt bricks will not cause forced movement of the salt bricks, reducing the possibility of the salt bricks colliding with each other due to movement.

[0074] Meanwhile, as the blocking box 32 swings, the auxiliary conveyor belt mechanism 22 continues to operate, allowing the salt bricks to fall into the blocking box 32 without the need for the auxiliary conveyor belt mechanism 22 to stop operating, thus ensuring that the salt brick forming and conveying are unaffected.

[0075] After the packaging bag is filled once, the empty packaging bag is opened again and needs to continue to be filled. At this time, the blocking box 32 swings downwards, causing the salt bricks inside the blocking box 32 to fall into the discharge hopper 12 to continue filling and bagging.

[0076] When the salt bricks conveyed inside the blocking box 32 and the top of the auxiliary conveyor belt mechanism 22 continue to fall, the salt bricks will fall directly from the top of the hopper 12 into the packaging bag. The salt bricks fall from a great height, and they are easily collided and broken, reducing the yield rate.

[0077] For this purpose, please refer to Figures 2-5 Two buffer mechanisms 33 are installed on the outer wall of the blocking box 32. One end of each buffer mechanism 33 is connected to a bearing plate 34. Multiple spring plates 37 are equidistantly connected to the side of the bearing plate 34 away from the buffer mechanism 33. When the blocking box 32 swings to the bottom of the auxiliary conveyor belt mechanism 22, the multiple spring plates 37 extend into the inside of the drop hopper 12. The blocked salt bricks slide down the inclined part inside the blocking box 32. At the same time, the salt bricks conveyed above the auxiliary conveyor belt mechanism 22 fall to the top of the spring plates 37. The elasticity of the spring plates 37 is used for auxiliary buffering. When the spring plates 37 are subjected to impact force, the spring plates 37 drive the bearing plate 34 to continue to swing downward. The bearing plate 34 uses the two buffer mechanisms 33 for secondary buffering and force relief.

[0078] See Figure 4 Both buffer mechanisms 33 include a fixed plate 331 connected to the blocking box 32. Two hinged plates 332 are hinged to the side wall of the fixed plate 331. A connecting block 333 is hinged between the ends of the two hinged plates 332 away from the fixed plate 331. The connecting block 333 is connected to the bearing plate 34. A spring rod 334 is hinged between one of the hinged plates 332 and the corresponding fixed plate 331. When the bearing plate 34 swings downward, it first causes the connecting block 333 to move synchronously, and simultaneously the hinged plate 332 swings downward and moves the spring rod 334. When pulled, the spring rod 334 buffers the swinging force of the hinge plate 332. If the spring plate 37 only remains stationary and the salt brick falls directly onto the surface of the spring plate 37 for buffering, the elasticity of the spring plate 37 will cause the salt brick to bounce up again. Therefore, while the spring plate 37 uses its own elasticity to buffer the salt brick, it also uses the swinging of the hinge plate 332 to perform secondary force relief, so that when the salt brick comes into contact with the spring plate 37, the spring plate 37 will move down a certain distance with the salt brick, reducing the chance of the salt brick bouncing up, and at the same time reducing the height of the salt brick when it falls and the breakage rate.

[0079] In Example 3, although the salt bricks are cushioned when they fall into the hopper 12, reducing the height difference, the packaging bag needs to stand upright during the packaging process. Due to the influence of the length of the packaging bag, there is still a large height difference when the salt bricks fall from the hopper 12 into the packaging bag. The collision force between the salt bricks is large, and the probability of the salt bricks breaking is still relatively high.

[0080] For this purpose, please refer to Figures 9-11 Two sorting mechanisms 428 are symmetrically installed on the side wall of the second suction cup group 429. The sorting mechanism 428 is used to grasp the packaging bag and adjust the height of the packaging bag to reduce the height difference when the material is dropped. The specific structure of the sorting mechanism 428 is as follows:

[0081] Both sets of sorting mechanisms 428 include telescopic cylinders 4281 installed on the side wall of the second suction cup group 429. The piston rods of the two telescopic cylinders 4281 are arranged opposite to each other. The ends of the piston rods of the telescopic cylinders 4281 are connected to L-shaped plates 4282. A fifth adjusting cylinder 4283 is installed on the top of the L-shaped plate 4282. The end of the piston rod of the fifth adjusting cylinder 4283 passes through the L-shaped plate 4282 and is connected to an electric gripper 4284. The two electric grippers 4284 are arranged opposite to each other. When the packaging bag is gripped and pulled open by the first suction cup group 417 and the second suction cup group 429, the packaging bag is in a drooping state. In this state, the two fifth adjusting cylinders 4283 respectively drive the corresponding L-shaped plates 4282 and electric grippers 4284 to move downward synchronously, causing... The electric gripper 4284 moves to the bottom corner of the packaging bag, and then the telescopic cylinder 4281 retracts, causing the L-shaped plate 4282, the fifth adjusting cylinder 4283, and the electric gripper 4284 to move towards the bottom corner of the packaging bag simultaneously. The gripping part of the electric gripper 4284 moves to both sides of the bottom corner, and then the electric gripper 4284 clamps the bottom corner of the packaging bag. After clamping, the two fifth adjusting cylinders 4283 retract simultaneously, and the electric gripper 4284 pulls the bottom corner of the packaging bag upward, causing this bottom corner to approach the top opening of the packaging bag. At this time, the height of the salt brick falling from the inside of the hopper 12 from the bottom of the packaging bag is reduced. When the salt brick falls, the drop height difference is reduced, further reducing the breakage rate of the salt brick.

[0082] As the salt bricks fall into the packaging bag, the two fifth adjusting cylinders 4283 gradually extend according to the falling salt bricks. The electric gripper 4284 pulls the bottom corners of the packaging bag downwards, and the packaging bag is gradually filled. After the packaging bag is filled, it is transferred to the sealing component 5 through the packaging conveyor belt mechanism 13 for sealing.

[0083] See Figures 9-11A drive motor 422 is installed on the top of the second support frame 421. The output end of the drive motor 422 extends into the interior of the second support frame 421 and is vertically connected to a lead screw 423. A sliding plate 424 is threadedly connected to the outer wall of the lead screw 423. The sliding plate 424 and the second support frame 421 are slidably connected through a guide rail slider. A support plate 426 is slidably connected to the top of the sliding plate 424. The support plate 426 is U-shaped and has a cushioning sponge pad structure on its top. A third adjusting cylinder 425 is installed on the top of the sliding plate 424. A through groove is opened on the side wall of the second support frame 421. The third adjusting cylinder 425 passes through the through groove. The piston rod end of the third adjusting cylinder 425 is connected to the support plate 426. The support plate 426 is used to support the bottom of the packaging bag to prevent the packaging bag from separating from the first suction cup group 417 and the second suction cup group 429 when the packaging bag is impacted by the falling salt brick.

[0084] Specifically, when the electric gripper 4284 pulls the bottom corner of the packaging bag upward, causing this bottom corner to approach the top opening of the packaging bag, the third adjusting cylinder 425 and the drive motor 422 start synchronously. The third adjusting cylinder 425 pushes the support plate 426 to move below the packaging bag. The drive motor 422 drives the lead screw 423 to rotate. When the lead screw 423 rotates, it drives the sliding plate 424 and the support plate 426 to move upward. The support plate 426 supports the bottom of the packaging bag. When the salt brick falls into the packaging bag, it first impacts the bottom of the packaging bag and the support plate 426. The support plate 426 supports the packaging bag to prevent the packaging bag from separating from the first suction cup group 417 and the second suction cup group 429 when the packaging bag is impacted by the falling salt brick.

[0085] When the salt bricks fall into the packaging bag, the cushioning sponge pad structure on the top of the pallet 426 cushions the first falling salt bricks, while the salt bricks that continue to fall are cushioned by the blocking component 3. At the same time, the electric gripper 4284 adjusts the height of the bottom of the packaging bag to reduce the drop height difference. This setting reduces the breakage rate of the salt bricks.
