Description

Technical Field

[0001] This utility model relates to the field of transportation devices, and in particular to a conveying device with an adaptive shaping structure. Background Technology

[0002] In automated material handling and packaging production lines, conveying devices play a crucial role in sequentially and orientingly transferring bulk or semi-finished materials to the next process. Their operational stability and the regularity of the material's posture directly impact the efficiency of subsequent packaging, palletizing, or processing. Due to the varying shapes and frequent dimensional fluctuations of incoming materials, skewness, stacking, or scattering often occur during conveying. Therefore, shaping structures are needed to gather and limit the materials, ensuring they enter downstream equipment in a neat and orderly manner.

[0003] Traditional conveying devices often employ fixed-width guide plates or manual adjustment mechanisms for shaping, which generally suffer from poor adaptability and cumbersome adjustments. The guide plate width typically requires manual pre-adjustment based on material specifications; when material dimensions change, the machine must be stopped and reset, making it unable to automatically adapt to continuously changing diameters or irregularly shaped materials. Fixed guide plates are prone to jamming or excessive compression when materials pass through, causing surface damage or conveyor blockage. Furthermore, the lack of synchronous linkage between the two guide plates leads to inconsistent opening and closing actions, causing material deviation, and the shaping height cannot be adjusted according to changes in material thickness, limiting the equipment's versatility. While some devices include reset elements, their complex structure and delayed response make it difficult to simultaneously meet the requirements of high-frequency conveying and stable shaping.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1

[0022] As attached Figures 1 to 6 The diagram illustrates a conveyor device with an adaptive shaping structure. A frame 1 serves as a fixed, integral load-bearing base on the mounting surface. A conveyor belt 2 is arranged around the upper part of the frame 1 and rotates horizontally in a circular motion. The upper surface of the conveyor belt 2 carries material forward. A shaping assembly 3 is positioned above the conveyor belt 2. A first shaping plate 301 and a second shaping plate 302 are connected to the left and right sides of the frame 1 respectively via hinge shafts. Both the first and second shaping plates 301 and 302 can rotate around the hinge shafts and are arranged opposite each other. An adjusting sliding hole 303, in the form of an elongated through-hole, penetrates the surfaces of both the first and second shaping plates 301 and 302, respectively. The long axis of the adjusting sliding hole 303 is parallel to the length direction of the plate.

[0023] The locking bolt 304 passes through the adjusting slide hole 303 from the outside of the first shaping plate 301 or the second shaping plate 302, and then through the lug hole at the end of the first connecting rod 403 or the second connecting rod 404. A washer is then fitted inside and a nut is used to limit its position, allowing the connecting rod end to both rotate and slide along the groove within the adjusting slide hole 303. An auxiliary reinforcing plate 305 is fitted and fixed to the edge of the adjusting slide hole 303 and protrudes from the plate surface to enhance the bending stiffness around the adjusting slide hole 303. A flexible pad 306 is bonded to the inner surfaces of the first shaping plate 301 and the second shaping plate 302, which face each other, using an elastic material. Outwardly expanding guide plates 307 are fixedly connected to the front ends of the first shaping plate 301 and the second shaping plate 302, respectively. The outwardly expanding guide plates 307 open outward relative to the inner side to form a trumpet-shaped guiding surface. The lower edge of the outwardly expanding guide plates 307 is close to the upper surface of the conveyor belt 2, and its front end position corresponds vertically to the front extension section of the conveyor belt 2 that crosses the frame 1. The wear-resistant layer 308 is coated on the outer surface of the flexible pad 306 and directly slides in contact with the material.

[0024] In the linkage guide assembly 4, the sliding assembly 401 is mounted on the upper surface of the sliding base plate 502, and is located above the conveyor belt 2. The slide block 402 straddles the sliding assembly 401 and can reciprocate. One end of the first connecting rod 403 is hinged to the left side of the slide block 402, and the other end is hinged to the first shaping plate 301. One end of the second connecting rod 404 is hinged to the right side of the slide block 402, and the other end is hinged to the second shaping plate 302. The reset member 405 consists of a helical compression spring 410 and a thrust retaining ring 411. The thrust retaining ring 411 is fixedly sleeved on the guide optical shaft 406, and the helical compression spring 410 is sleeved on the guide optical shaft 406, with one end abutting against the end face of the thrust retaining ring 411 and the other end abutting against the end face of the sliding sleeve 408.

[0025] The sliding assembly 401 consists of a guide optical shaft 406 and an end support 407. The end support 407 is fixed to the frame 1, and the guide optical shaft 406 passes through the central hole of the end support 407 and is clamped and fixed. The slide block 402 includes a sliding sleeve 408 and a side wing plate 409. The sliding sleeve 408 is fitted around the outer circumference of the guide optical shaft 406 with a clearance fit. The side wing plates 409 are symmetrically welded to both sides of the sliding sleeve 408, and their protruding ends are respectively hinged to the first connecting rod 403 and the second connecting rod 404. The reset component 405 includes a helical compression spring 410 and a thrust retaining ring 411. The thrust retaining ring 411 is fixedly fitted on the guide optical shaft 406, and the helical compression spring 410 is arranged around the guide optical shaft 406, with one end abutting against the end face of the thrust retaining ring 411 and the other end abutting against the end face of the sliding sleeve 408.

[0026] When the first shaping plate 301 and the second shaping plate 302 are pushed outward by the material, the first connecting rod 403 and the second connecting rod 404 pull the lateral wing plate 409. The lateral wing plate 409 drives the sliding sleeve 408 to slide along the guide optical axis 406 toward the thrust retaining ring 411. The sliding sleeve 408 compresses the spiral spring 410 to store energy. After the material passes, the thrust disappears, and the spiral spring 410 releases energy to push the sliding sleeve 408 to slide in the opposite direction. Through the lateral wing plate 409, the first connecting rod 403 and the second connecting rod 404, the first shaping plate 301 and the second shaping plate 302 are pushed to swing inward. When the rotating handwheel 504 is rotated to adjust the height of the sliding base plate 502, the outer end hinge point of the first connecting rod 403 and the second connecting rod 404 slides up and down along the adjusting sliding hole 303 to compensate for the height change between the sliding base plate 502 and the first shaping plate 301 and the second shaping plate 302.

[0027] The height adjustment assembly 5 is arranged between the frame 1 and the sliding assembly 401. Guide columns 501 are vertically erected on both sides of the frame 1 and fixedly connected. The sliding base plate 502 has guide holes and is fitted onto the outer wall of the guide column 501, allowing it to slide up and down along the guide column 501. The drive screw 503 passes vertically through the central threaded hole of the sliding base plate 502 and engages with the threaded connection of the sliding base plate 502 for transmission. The rotary handwheel 504 is fixedly mounted on the top of the drive screw 503 and has a gripping part on its outer edge. The thrust bearing 505 is fitted between the lower end face of the rotary handwheel 504 and the upper end face of the frame 1, bearing axial pressure and allowing relative rotation. The sliding assembly 401 is integrally fixed to the upper surface of the sliding base plate 502. When the rotary handwheel 504 is rotated, the drive screw 503 rotates accordingly, driving the sliding base plate 502 to rise and fall along the guide column 501 through the threaded pair. The sliding base plate 502 drives the sliding assembly 401 and the connected slide block 402, first connecting rod 403, second connecting rod 404, first shaping plate 301, and second shaping plate 302 to rise and fall together, realizing the height adjustment of the shaping assembly 3 relative to the conveyor belt 2.

[0028] The top pressure assembly 6 is located between the first shaping plate 301 and the second shaping plate 302. The bridging gantry 601 is an inverted U-shaped frame, with both ends fixed to the left and right sides of the frame 1, spanning across the conveyor belt 2. The pressure roller 602 is a cylindrical roller, with both ends hinged to the inner wall of the bridging gantry 601 via bearing seats. Its axis is perpendicular to the forward direction of the conveyor belt 2, and its lower edge is lower than the upper edges of the first shaping plate 301 and the second shaping plate 302. When the material passes under the pressure roller 602, its upper surface contacts the pressure roller 602 and is pushed upward. The pressure roller 602 rotates freely around the hinge axis, and at the same time, under its own gravity, it applies a vertical downward rolling pressure to the upper surface of the material.

[0029] The protective cover 7 completely covers the sliding assembly 401 and the slide block 402, and its edges are fixed to the sliding base plate 502 or the frame 1 by screws. Clearance holes 701 are formed in the side wall of the protective cover 7. The first connecting rod 403 and the second connecting rod 404 pass through the corresponding clearance holes 701 and extend to the outside of the protective cover 7. When the slide block 402 moves along the sliding assembly 401, the first connecting rod 403 and the second connecting rod 404 move accordingly within the clearance holes 701. The walls of the clearance holes 701 limit their lateral swing amplitude and prevent external debris from entering the interior of the protective cover 7.

[0030] Example 2

[0031] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below, with reference to the specific working method described in detail: Furthermore, the end support 407 is fixedly installed on the frame 1, and the guide optical shaft 406 passes through the end support 407. The two ends of the guide optical shaft 406 are respectively limited and supported by two end supports 407. The end support 407 and the guide optical shaft 406 are locked and fixed by set screws to maintain relative stillness. The outer surface of the guide optical shaft 406 serves as the linear guide track of the sliding component 401.

[0032] Furthermore, the sliding sleeve 408 is coaxially sleeved outside the guide optical axis 406 and slides linearly along the axial direction of the guide optical axis 406. The lateral wing plate 409 is integrally formed or fixedly connected to the outer wall of the sliding sleeve 408 and extends to both sides. One end of the first connecting rod 403 is hinged to one side of the lateral wing plate 409 and the other end is hinged to the first shaping plate 301. One end of the second connecting rod 404 is hinged to the other side of the lateral wing plate 409 and the other end is hinged to the second shaping plate 302. When the first shaping plate 301 and the second shaping plate 302 are stretched open by the material and rotate outward, the first connecting rod 403 and the second connecting rod 404 respectively pull the lateral wing plate 409, thereby driving the sliding sleeve 408 to slide along the guide optical axis 406.

[0033] Furthermore, the thrust retaining ring 411 is fixedly installed on the guide optical shaft 406 and located at one end of the sliding path of the sliding sleeve 408. The spiral compression spring 410 is coaxially sleeved on the outside of the guide optical shaft 406. One end of the spiral compression spring 410 abuts against the end face of the thrust retaining ring 411 and the other end abuts against the end face of the sliding sleeve 408. When the sliding sleeve 408 slides along the guide optical shaft 406 toward the thrust retaining ring 411, the spiral compression spring 410 is compressed and stores elastic force. When the external force of the material spreading on the first shaping plate 301 and the second shaping plate 302 decreases, the elastic force of the spiral compression spring 410 pushes the sliding sleeve 408 to slide in the opposite direction along the guide optical shaft 406, and drives the first shaping plate 301 and the second shaping plate 302 to reset via the first connecting rod 403 and the second connecting rod 404.

[0034] Furthermore, the adjusting sliding hole 303 is formed on the first shaping plate 301 and the second shaping plate 302 and is an elongated through hole. The locking bolt 304 passes through the adjusting sliding hole 303 and locks the hinge position of the first connecting rod 403 or the second connecting rod 404 onto the first shaping plate 301 or the second shaping plate 302. The auxiliary reinforcing plate 305 is fixedly installed around the adjusting sliding hole 303 and fits against the surface of the first shaping plate 301 or the second shaping plate 302. The auxiliary reinforcing plate 305 is used to enhance the structural strength of the edge of the adjusting sliding hole 303. When the locking bolt 304 is loosened, the hinge point of the first connecting rod 403 and the second connecting rod 404 can move along the adjusting sliding hole 303 to adjust the initial included angle between the first shaping plate 301 and the second shaping plate 302. After the locking bolt 304 is locked, the position of the hinge point is fixed.

[0035] Furthermore, the flexible pad 306 is attached and fixed to the side surfaces of the first shaping plate 301 and the second shaping plate 302 that are close to each other. The outwardly expanding guide plate 307 is fixedly installed at the ends of the first shaping plate 301 and the second shaping plate 302 and is inclined outward relative to the flexible pad 306. The wear-resistant layer 308 covers the outer surface of the flexible pad 306 and is in direct contact with the material. When the material moves along the conveyor belt 2 to the space between the first shaping plate 301 and the second shaping plate 302, the material first contacts the inclined surface of the outwardly expanding guide plate 307 and is guided into the channel defined by the flexible pad 306. As the material continues to move forward, it pushes the flexible pad 306 and the wear-resistant layer 308, thereby driving the first shaping plate 301 and the second shaping plate 302 to rotate outward.

[0036] Furthermore, the guide column 501 is vertically fixedly installed on the frame 1, the sliding base plate 502 is slidably sleeved on the outside of the guide column 501 and moves up and down along the axis of the guide column 501, the drive screw 503 is vertically inserted into the sliding base plate 502 and threadedly engaged with the sliding base plate 502, the lower or upper end of the drive screw 503 is rotatably supported on the frame 1, and the sliding assembly 401 is fixedly installed on the sliding base plate 502 as a whole; when the drive screw 503 is rotated, the rotation of the drive screw 503 drives the sliding base plate 502 to rise and fall along the guide column 501, and the sliding base plate 502 drives the sliding assembly 401 to rise and fall synchronously, thereby adjusting the height position of the sliding assembly 401 and the first shaping plate 301 and the second shaping plate 302 linked with it relative to the conveyor belt 2.

[0037] Furthermore, the rotary handwheel 504 is fixedly installed at the upper or lower end of the drive screw 503, and the thrust bearing 505 is disposed between the rotary handwheel 504 and the frame 1 and abuts against the end face of the rotary handwheel 504 and the corresponding end face of the frame 1 respectively. When the rotary handwheel 504 is manually rotated, the rotary handwheel 504 drives the drive screw 503 to rotate synchronously. The thrust bearing 505 transmits the axial pressure transmitted by the rotary handwheel 504 to the frame 1 and reduces the rotational friction resistance. The rotation of the drive screw 503 drives the sliding base plate 502 to rise and fall along the guide column 501 through the threaded engagement, thereby adjusting the height of the sliding assembly 401.

[0038] Furthermore, the left and right legs of the gantry 601 are fixed on the left and right longitudinal beams of the frame 1 and located on the outside of the first shaping plate 301 and the second shaping plate 302. The crossbeam spans the conveyor belt 2 above, and the position of the left and right legs will not affect the opening of the first shaping plate 301 and the second shaping plate 302. The pressure roller 602 is hinged at both ends to the bridging gantry 601, and the axis of the pressure roller 602 is perpendicular to the conveying direction of the conveyor belt 2. The lower edge of the pressure roller 602 is lower than the lower end face of the bridging gantry 601 and the upper edge of the first shaping plate 301 and the second shaping plate 302. A passage gap slightly smaller than the height of the material is left between the pressure roller 602 and the upper surface of the conveyor belt 2. When the material passes under the pressure roller 602 after being shaped by the first shaping plate 301 and the second shaping plate 302, the upper surface of the material contacts and pushes the pressure roller 602 upward. The pressure roller 602 rotates relative to the bridging gantry 601 and applies downward pressure to the upper surface of the material under its own weight or elastic force, so that the top of the material is rolled flat.

[0039] Furthermore, the protective cover 7 is fixedly installed on the outside of the sliding assembly 401 and the slide 402 and mounted on the frame 1. The clearance hole 701 is opened on the side wall of the protective cover 7 and is an elongated through hole. The first connecting rod 403 and the second connecting rod 404 pass through the corresponding clearance hole 701 and extend to the outside of the protective cover 7. When the slide 402 slides along the sliding assembly 401, the first connecting rod 403 and the second connecting rod 404 move with the slide 402 in the clearance hole 701. The hole wall of the clearance hole 701 provides clearance space for the movement of the first connecting rod 403 and the second connecting rod 404 and limits their swing range.
