Description

Technical Field

[0001] This invention relates to the field of automated material handling and conveying equipment, and in particular to a quick-change attitude conversion outlet device for an automatic cylindrical material handling machine. Background Technology

[0002] In the automatic feeding, inspection, assembly, or conveying of cylindrical materials such as bearing rollers, short cylindrical parts, cylindrical pins, and similar workpieces, it is usually necessary to first pass through a material handling mechanism to form a relatively uniform arrangement of the materials before sending them to the subsequent conveyor line or processing station. Since the material discharge method at the bottom of the hopper is mostly vertical drop, while the subsequent conveying or receiving station usually requires the material to enter in a horizontal or near-horizontal posture, setting up a posture conversion structure between the material handling port and the conveyor line to smoothly convert the cylindrical materials from a vertical state to a horizontal state is an important link to ensure the continuous operation of automated equipment. In existing equipment, bent pipes, bent grooves, guide slides, or additional tilting mechanisms are often used to complete this kind of posture conversion, and guide plates, adjusting slides, and other structures are used to adapt to materials of different specifications.

[0003] However, conventional bend structures mainly rely on the tube cavity to restrict the material's posture, usually requiring the tube diameter to match the material diameter. When specifications change, problems such as excessive gaps, increased friction, or the need to replace different bends can easily occur. Conventional curved channels or simple arc-shaped slides mostly rely on bottom support to guide the material downhill, which is insufficient in restricting the sides and upper sides of cylindrical materials. Under the action of gravity and inertia, the material is prone to rolling, swaying, or chaotic discharge posture. Moreover, for cylindrical materials of various specifications, the effective inner diameter of the feeding port, the receiving position of the slide entrance, and the guiding and restricting space need to be matched with each other. If only the feeding port or the slide position is adjusted, it is easy to cause the material landing point to deviate, the entry into the slide to be unsmooth, or the need for repeated manual alignment. Therefore, there is still room for improvement in the existing posture conversion structures in terms of achieving stable anti-rollover guidance, multi-specification adaptation, and coordinated alignment of the feeding port and the slide entrance in a compact space. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the existing cylindrical material posture conversion structure mostly relies on bent pipes, ordinary bent grooves or separate adjustment mechanisms, which have problems such as insufficient restriction on preventing material overturning, need for frequent replacement or repeated alignment when adapting to multiple specifications, and difficulty in coordinating and matching the material feeding port and the slide inlet. To this end, we propose a quick-change posture conversion outlet device for an automatic cylindrical material feeding machine.

[0005] To achieve the above objectives, this application adopts the following technical solution: a quick-change attitude conversion outlet device for an automatic cylindrical material feeder, comprising a mounting base, a hopper, a feeder opening, an attitude conversion slide, a guide plate, and a guide plate adjustment mechanism; The hopper is mounted on the mounting base, and the material discharge port is located at the lower end of the hopper and is used to vertically discharge cylindrical materials. The attitude conversion slide is located below the mounting base and corresponds to the material feeding port. The attitude conversion slide has a downward turning path extending from the receiving end near the material feeding port to the discharge end. The downward turning path is used to guide the cylindrical material from a vertical or near-vertical attitude to a horizontal or near-horizontal attitude. One side of the attitude conversion slide has an angled support groove that extends continuously along the downward turning path. The angled support groove forms a consistent angled support profile on each tangential section along the downward turning path. The angled support profile is used to support the lower part or the lower side of the cylindrical material. The guide plates are arranged in pairs on both sides of the attitude conversion slide. The side of the guide plate facing the attitude conversion slide has an inclined surface. The inclined surface is located on the opening side of the included angle support groove, and together with the included angle support groove, they form a restricted guiding space extending along the downward turning path, so that the cylindrical material is supported and limited when it slides down and turns along the attitude conversion slide under its own gravity. The guide plate adjustment mechanism is connected to the guide plate and is used to adjust the distance between the two guide plates.

[0006] Preferably, the angled support profile includes an intersecting or adjacent first support surface and a second support surface, and a support area for supporting the lower or lower side of a cylindrical material is formed between the first support surface and the second support surface. The angled support profile extends continuously along the downward turning path to form a track surface.

[0007] Preferably, the guide plate is arranged along the extension direction of the attitude conversion slide, and the included angle support groove and the inclined surfaces of the two side guide plates together form a cross-sectional restriction area at multiple cross-sectional positions of the attitude conversion slide. The multiple cross-sectional restriction areas continuously sweep along the downward turning path to form the restricted guide space.

[0008] Preferably, the mounting base is provided with a mounting frame at its bottom, a first adjusting frame is movably mounted on one side of the mounting frame, the attitude conversion slide is mounted on the first adjusting frame, and the guide plate adjusting mechanism is mounted on the first adjusting frame.

[0009] Preferably, the guide plate adjustment mechanism includes a bidirectional lead screw rotatably mounted on a first adjustment frame and traction frames threaded to both ends of the bidirectional lead screw. The two guide plates are detachably mounted on the two traction frames. When the bidirectional lead screw rotates, it drives the two traction frames to move closer or further apart from each other to adjust the distance between the two guide plates.

[0010] Preferably, the traction frame and the first adjusting frame are connected by a movable guide to guide the traction frame to move along the adjusting direction of the guide plate.

[0011] Preferably, the first adjusting frame is connected to the movable guide of the mounting frame on the side near the mounting frame. An adjusting knob is rotatably provided on the first adjusting frame, and the adjusting knob is connected to a gear. A rack that meshes with the gear is provided on the mounting frame. The adjusting knob drives the first adjusting frame, the attitude conversion slide, and the guide plate to move relative to the material feeding port through the cooperation of the gear and the rack.

[0012] Preferably, the feeding port is provided with an inner diameter adjustment component. The inner diameter adjustment component includes multiple adjustment plates arranged circumferentially along the feeding port and movable radially along the feeding port, a drive plate corresponding to the adjustment plates, a guide groove arranged on the adjustment plates, and a guide block arranged on the drive plate. The multiple adjustment plates together form a feeding channel for cylindrical materials to pass through. The guide block and the guide groove are movably guided and cooperated to drive the adjustment plates to move radially along the feeding port when the drive plate moves vertically.

[0013] Preferably, a traction rotating ring is provided on the lower outer side of the material handling port, a traction seat is provided on the traction rotating ring, a traction hole is provided on the traction seat, and a traction rod is provided on one side of the attitude conversion slide that is movably inserted into the traction hole. When the first adjusting frame drives the attitude conversion slide to move, the traction rod can drive the traction seat and the traction rotating ring to rise and fall through the traction hole.

[0014] Preferably, it also includes a conveying device, which is located below the exit of the attitude conversion slide; The conveying device is provided with a fixed frame, and a second adjusting frame is movably mounted on the fixed frame. One end of the second adjusting frame is rotatably provided with a buffer roller corresponding to the outlet of the attitude conversion slide. The fixed bracket is threaded with an adjusting screw for adjusting the position of the second adjusting bracket.

[0015] The technical effects and advantages of this invention are as follows: In this invention, cylindrical materials fall vertically from the feeding port and enter the restricted guiding space formed by the attitude conversion slide and the two side guide plates. The attitude conversion slide supports the lower part of the material through the angled support groove extending along the material turning path, and the two side guide plates restrict the material's side by facing the inclined surfaces towards the attitude conversion slide. Under the action of its own gravity, the material gradually completes the transformation from a vertical posture to a horizontal or near-horizontal posture along a predetermined trajectory. This structure can simultaneously provide support and restriction during the attitude conversion process, reducing the rolling, swaying, and posture confusion of the cylindrical material when it slides down and turns, improving the consistency of the discharge posture, and allowing the material to enter the subsequent conveying device more smoothly.

[0016] In this invention, the two guide plates achieve symmetrical spacing adjustment through bidirectional lead screws and traction frames, allowing the restricted space formed by the guide plates to accommodate cylindrical materials of different diameters. Simultaneously, when the first adjustment frame drives the attitude conversion slide and the guide plates to move as a whole, it can drive the adjustment plate in the material handling opening to move radially through the cooperation of the traction rod, traction hole, traction seat, traction ring, drive plate, guide block, and guide groove, so that the effective inner diameter change of the material handling opening matches the change of the inlet position of the attitude conversion slide. Thus, during the changeover, the specifications of the material dropping channel and the receiving position of the slide can be adjusted simultaneously, reducing the drop point offset and repeated alignment caused by individual debugging, and improving the changeover efficiency and continuous operation stability of cylindrical materials of multiple specifications.

Detailed Implementation

[0019] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0020] Reference Figures 1-12 As shown, this invention provides a quick-change posture conversion outlet device for an automatic cylindrical material feeder, including a mounting base 1. The mounting base 1 is used to install on a designated frame or the main body of the automatic feeding equipment. A feeding mechanism is installed on the mounting base 1. The feeding mechanism is used to initially sort the cylindrical materials and guide them one by one into the posture conversion area below. The feeding mechanism includes a conical hopper 2 installed on the mounting base 1. The hopper 2 is used to store the cylindrical materials to be sorted. The cylindrical materials can be rollers, short cylindrical parts, cylindrical pins, short tubular parts, or other workpieces with a shape similar to a cylinder. A feeding port 8 is rotatably provided on the inner side of the lower end of the hopper 2 and communicates with the hopper 2. A feeding block 12 for feeding is provided on the upper end of the feeding port 8. When the material handling block 12 rotates with the material handling port 8, it can disturb, straighten and disperse the cylindrical material at the bottom of the hopper 2, so that the cylindrical material enters the material handling port 8 one by one, reducing the situation of overlapping, oblique insertion, stacking or multiple pieces entering at the bottom of the hopper 2, thereby providing a more stable vertical single-piece dropping condition for the attitude conversion component below.

[0021] To achieve the rotational feeding of the feeding port 8, a feeding motor 3 is also installed on the mounting base 1. Pulleys 13 are provided at the bottom of the mounting base 1 corresponding to the feeding motor 3 and at the lower outer end of the feeding port 8. The output shaft of the feeding motor 3 is rigidly connected to the corresponding pulley 13. A belt 6 is provided on the two pulleys 13. The feeding motor 3 can achieve the rotation of the feeding port 8 through the cooperation of the pulleys 13 and the belt 6. Using pulleys 13 and belt 6 for transmission facilitates the placement of the feeding motor 3 on the side or top of the mounting base 1, avoiding the feeding motor 3 directly occupying the posture conversion space below the feeding port 8. Furthermore, it allows the feeding port 8 to achieve a relatively stable rotational motion, which is beneficial for the feeding block 12 to continuously process materials. The cylindrical materials processed by the hopper 2 and the feeding port 8 can fall vertically or nearly vertically from the feeding port 8.

[0022] A posture conversion component is installed below the mounting base 1, and a conveying device 4 is installed below the posture conversion component. The posture conversion component is used to receive cylindrical materials falling from the feed port 8 and guide the cylindrical materials from a vertical or near-vertical posture to a horizontal or near-horizontal posture. The posture conversion component includes a posture conversion slide 5 installed below the mounting base 1 and corresponding to the feed port 8. One side of the posture conversion slide 5 has an angled support groove corresponding to the feed port 8. The angled support groove extends along the downward turning path of the cylindrical materials. The downward turning path refers to the movement path of the cylindrical materials after being discharged from the feed port 8, sliding down the posture conversion slide 5 and gradually changing from a vertical or near-vertical posture to a horizontal or near-horizontal posture. The downward turning path gradually transitions from a vertical receiving position near the feed port 8 to a horizontal or near-horizontal discharge position near the conveying device 4. The tangential direction of the downward turning path... A cross section refers to the cross section taken at the corresponding position on the downward turning path, with the tangent direction of the path at that position as the reference. The angled support groove forms a consistent angled support profile on each tangential cross section along the downward turning path, at least within the continuous working section used to support cylindrical materials. The angled support profile can be understood as being formed by the intersection or adjacency of the first support surface and the second support surface, and a support area for supporting the lower or lower side of the cylindrical material is formed between the first support surface and the second support surface. The angled support profile extends continuously along the downward turning path, thereby forming a track surface for guiding the cylindrical material to turn. It should be noted that the inlet end, outlet end, installation transition, chamfer, or local avoidance point of the attitude conversion slide 5 can be provided with transition structures according to the assembly and discharge needs. The transition structure does not affect the angled support groove's function of providing angled support for the cylindrical material within the continuous working section.

[0023] It should be noted that the attitude conversion slide 5 is not an ordinary cylindrical bend, nor is it an ordinary bend with only a single bottom support surface; the attitude conversion slide 5 provides support for cylindrical materials in two directions through the included angle support groove, so that when the cylindrical materials slide down the attitude conversion slide 5 under their own weight, they can gradually change their direction of movement while being supported; since the included angle support groove extends along the turning path formed by the arc or the combination of straight and arc segments, the cylindrical materials can gradually transition from a vertical falling state to a horizontal or near-horizontal discharge state.

[0024] To further limit and guide the material, a guide plate 10 corresponding to the attitude conversion slide 5 is also provided below the mounting base 1. The two guide plates 10 are symmetrically arranged on both sides of the attitude conversion slide 5. The guide plates 10 are arranged along the extension direction of the attitude conversion slide 5, and each guide plate 10 has an inclined surface on the side facing the attitude conversion slide 5. The inclined surfaces of the two guide plates 10 are located on the opening side of the angle support groove, and together with the angle support groove of the attitude conversion slide 5, they limit the movement space of the cylindrical material. When the cylindrical material slides down the attitude conversion slide 5, its lower part or lower side is supported by the angle support groove, and its two sides or upper side is constrained by the inclined surfaces of the two guide plates 10, so that the cylindrical material cannot roll or swing freely in the slide.

[0025] Specifically, at multiple cross-sectional locations of the attitude conversion slide 5, the angled support groove and the inclined surfaces of the two side guide plates 10 together form a cross-sectional restriction zone adapted to the outer periphery of the cylindrical material. Multiple cross-sectional restriction zones are continuously arranged along the material turning path, thereby forming a restricted guiding space extending along the attitude conversion slide 5. After the cylindrical material enters this restricted guiding space, it is not completely guided by the cavity surrounding it like material in a normal bend, nor is it supported only by the bottom bend like material in a normal trough. Instead, it slides down along a predetermined trajectory under the joint restriction of the angled support groove and the two side guide plates 10, thereby completing the attitude conversion and suppressing overturning.

[0026] The advantages of the above structure are as follows: Ordinary bends mainly rely on matching the pipe diameter with the material diameter to constrain the material. When the specifications change, problems such as pipe diameter mismatch, increased friction, or the need to replace the bend may easily occur. Ordinary bends usually only provide bottom guidance, and the material may still roll under the action of gravity and inertia. This solution provides support in two directions through the included angle support groove and provides lateral restraint through the guide plates 10 on both sides, so that the trajectory envelope of the cylindrical material is continuously controlled. Therefore, it can realize the gravity-based attitude conversion from vertical to horizontal or near-horizontal in a relatively compact space and improve the consistency of the discharge attitude.

[0027] It should be noted that a mounting bracket 9 is bolted to the bottom of the mounting base 1, and a first adjusting bracket 7 is provided on one side of the mounting bracket 9. The attitude conversion slide 5 is bolted to the first adjusting bracket 7. The first adjusting bracket 7 serves as the mounting base for the attitude conversion slide 5 and the guide plate adjustment mechanism described below. The mounting bracket 9 is used to install the first adjusting bracket 7 below the mounting base 1 and to provide position adjustment support for the first adjusting bracket 7. By installing the attitude conversion slide 5 on the first adjusting bracket 7, the attitude conversion slide 5, guide plate 10, and related adjustment structures can form a relatively centralized attitude conversion module, which facilitates assembly, debugging, and subsequent maintenance.

[0028] To accommodate products of different specifications, this invention also includes a guide plate adjustment mechanism. The guide plate adjustment mechanism includes a bidirectional lead screw 15 rotatably mounted on a first adjustment frame 7. Traction frames 14 are symmetrically threaded at both ends of the bidirectional lead screw 15. The guide plate 10 is detachably mounted on the bottom of the traction frame 14, either by bolts or by magnetic attraction, facilitating the replacement of guide plates 10 of different specifications. To reduce weight, the guide plate 10 can be designed as a hollow structure or have process holes machined into it. When the bidirectional lead screw 15 rotates, the two traction frames 14 can move synchronously in opposite directions, thereby driving the two guide plates 10 to move closer or further away synchronously, thus changing the restricted space between the two guide plates 10.

[0029] To increase the stability of the guide plate 10 displacement, a slider is provided on the traction frame 14, and a linear guide rail corresponding to the traction frame 14 is provided on the first adjustment frame 7. The slider on the traction frame 14 is movably connected to the linear guide rail, thereby increasing the stability and accuracy of the guide plate 10 when adjusting its displacement. Since the two guide plates 10 are symmetrically adjusted through the bidirectional lead screw 15, the center plane between the two guide plates 10 can remain basically unchanged, avoiding the deviation of the movement center of the cylindrical material from the predetermined support area of ​​the attitude conversion slide 5 due to unilateral adjustment.

[0030] The advantages of the above-mentioned guide plate adjustment mechanism are as follows: the spacing of the same group of guide plates 10 can be adjusted through the guide plate adjustment mechanism to cover the materials within the corresponding specification range; this structure avoids configuring a complete attitude conversion slide 5 for each specification, and can cover multiple specification ranges with a limited number of guide plate groups 10; in other words, this solution does not adapt to all material specifications by replacing bends of different diameters, but provides a stable basic steering trajectory through the attitude conversion slide 5, and then matches cylindrical materials of different diameter ranges through the replaceability and spacing adjustment of the guide plates 10, thereby taking into account the convenience of changeover, manufacturing cost and attitude conversion stability.

[0031] To accommodate materials of different specifications, the feeding port 8 is equipped with an inner diameter adjustment assembly. This assembly includes an adjustment plate 22 located on the inner periphery of the feeding port 8 and movable radially along it. Multiple adjustment plates 22 are arranged circumferentially around the feeding port 8, forming a discharge channel for cylindrical materials. A drive plate 23, corresponding to the adjustment plate 22, is vertically arranged on the inner periphery of the feeding port 8. The adjustment plate 22 has an inclined guide groove 24, and the drive plate 23 has a guide block 25 that movably guides the guide groove 24. The guide block 25 is preferably a rotatably connected roller structure to reduce guiding friction. When the drive plate 23 moves vertically, the guide block 25 slides within the inclined guide groove 24. The guide groove 24 converts the vertical displacement of the drive plate 23 into the radial displacement of the adjustment plates 22, causing the multiple adjustment plates 22 to move synchronously inward or outward, thereby changing the effective inner diameter of the discharge channel.

[0032] The lower outer side of the feeding port 8 is connected to a traction ring 18 via a bearing assembly that can be vertically displaced. A traction seat 19 is provided on one side of the traction ring 18, and a traction hole 21 is provided on the traction seat 19. A traction rod 20 that is movably inserted into the traction hole 21 is installed on one side of the attitude conversion slide rail 5. The traction ring 18 cooperates with the feeding port 8 through the bearing assembly. On the one hand, it can transmit the external traction received by the traction seat 19 to the drive plate 23, so that the drive plate 23 can generate vertical displacement. On the other hand, it can prevent the traction seat 19 from directly restricting the rotation of the feeding port 8, so that the feeding port 8 can still rotate and feed materials under the drive of the feeding motor 3.

[0033] The mounting frame 9 is equipped with a linear guide rail, and the first adjusting frame 7 is equipped with a slider that is movably connected to the linear guide rail on the side near the mounting frame 9. An adjusting knob 11 is rotatably provided at the end of the first adjusting frame 7 near the mounting frame 9. A gear 17 is provided on the adjusting knob 11, and a rack 16 that meshes with the gear 17 is provided on the mounting frame 9. Thus, by turning the adjusting knob 11, the displacement of the first adjusting frame 7, the attitude conversion slide 5, and the guide plate 10 as a whole can be realized. This position adjustment is used to change the position of the upper end of the attitude conversion slide 5 relative to the outlet of the material handling port 8, so that the angle support groove of the attitude conversion slide 5 can correspond to the falling position of materials of different diameters, reducing the situation where materials collide with the edge, deviate, or fail to enter the angle support groove smoothly after being discharged from the material handling port 8.

[0034] In order to change the inner diameter of the material feeding port 8 while adjusting the position of the attitude conversion slide 5, the traction hole 21 can be set as an inclined guide hole, or the linear guide rail on the mounting frame 9 can have an inclined guide component relative to the material feeding port 8. In this embodiment, the inclined guide cooperation between the traction hole 21 and the traction rod 20 is preferred. When the first adjustment frame 7 drives the attitude conversion slide 5 to move along the mounting frame 9, the traction rod 20 moves synchronously with the attitude conversion slide 5. The traction rod 20 slides in the traction hole 21 and pushes the traction seat 19 to produce vertical displacement. The traction seat 19 drives the traction ring 18 to rise and fall. The traction ring 18 then drives the drive plate 23 to move vertically. The drive plate 23 drives the adjustment plate 22 to move radially through the cooperation of the guide block 25 and the guide groove 24, thereby changing the effective inner diameter of the material feeding channel in the material feeding port 8.

[0035] The above structure links the position adjustment of the attitude conversion slide 5 with the inner diameter adjustment of the material feeding port 8. Specifically, when the adjusting plate 22 moves radially inward to reduce the inner diameter of the material feeding channel, the first adjusting frame 7 simultaneously moves the attitude conversion slide 5 towards the side closer to the center line of the material feeding port 8, so that smaller diameter cylindrical materials can still fall into the support area of ​​the angled support groove after being discharged from the reduced material feeding channel. When the adjusting plate 22 moves radially outward to increase the inner diameter of the material feeding channel, the first adjusting frame 7 simultaneously moves the attitude conversion slide 5 away from the center line of the material feeding port 8, so that larger diameter cylindrical materials can still maintain a tangential or approximately tangential receiving relationship with the entrance of the angled support groove after being discharged from the enlarged material feeding channel. Thus, the operator can simultaneously complete the adaptation of the inner diameter of the material feeding port 8 and the alignment of the entrance of the attitude conversion slide 5 with one adjustment, avoiding mismatch of the slide entrance receiving position due to adjusting only the inner diameter of the material feeding port 8, and also avoiding the inability to adapt to the material diameter due to adjusting only the slide position.

[0036] The technical effect of this linkage adjustment structure is that: when changing the shape of cylindrical materials of different specifications, it is not necessary to frequently change the material feeding port 8 with different inner diameters, nor is it necessary to repeatedly adjust the receiving position of the posture conversion slide 5; there is a mechanical linkage between the change of inner diameter and the change of slide alignment, which can improve the efficiency of changing the shape, reduce the error of manual adjustment, and make the process of material entering the posture conversion slide 5 from the material feeding port 8 more stable.

[0037] It should be noted that the material discharged from the aforementioned attitude conversion slide 5 generally falls into the conveying device 4 located below the attitude conversion slide 5. The conveying device 4 is used to transport cylindrical materials. The conveying device 4 is generally installed on the frame. The attached figure only shows a part of the conveying device 4. The specific principle and structure of the conveying device 4 will not be described in detail. The conveying device 4 can adopt a chain plate conveyor or other conveying structure suitable for receiving cylindrical materials, as long as it can receive cylindrical materials in a horizontal or near-horizontal state at the outlet of the attitude conversion slide 5.

[0038] To buffer and decelerate the material discharged from the attitude conversion slide 5, a fixed frame 26 is provided on the conveying device 4. A second adjusting frame 27 is movably mounted on the fixed frame 26. One end of the second adjusting frame 27 is rotatably equipped with a buffer roller 28 corresponding to the outlet of the attitude conversion slide 5. The buffer roller 28 is a polyurethane inert roller. To adjust the position of the buffer roller 28, an adjusting screw 29 is threaded on the fixed frame 26. The lower end of the adjusting screw 29 is used to control the change of the tilt angle of the second adjusting frame 27, thereby adjusting the position of the buffer roller 28 to adapt to materials of different specifications.

[0039] After cylindrical materials are turned to a horizontal or near-horizontal state by the attitude conversion slide 5, they usually have a certain outward speed. If they directly enter the conveying device 4, they are prone to bouncing, rolling or attitude confusion due to excessive speed. By lightly contacting the material with the buffer roller 28, the material can be decelerated and stably supported after it rushes out of the attitude conversion slide 5, so that the material enters the conveying device 4 more smoothly. The adjusting screw 29 is used to adjust the distance between the buffer roller 28 and the conveying device 4, so that the buffer roller 28 can be adapted to cylindrical materials of different diameters.

[0040] The working principle of this invention is as follows: During operation, the feeding motor 3 drives the feeding port 8 to rotate via the pulley 13 and belt 6. The feeding block 12 at the upper end of the feeding port 8 rotates accordingly and organizes the cylindrical materials at the bottom of the hopper 2, causing the cylindrical materials to enter the feeding port 8 one by one and fall downwards in a vertical or near-vertical posture. After being discharged from the feeding port 8, the cylindrical materials enter the upper end of the posture conversion slide 5. The angled support groove on the posture conversion slide 5 supports the lower or lower side of the cylindrical materials. Under the action of their own gravity, the cylindrical materials slide down the track surface of the posture conversion slide 5 and gradually change from a vertical posture to a horizontal or near-horizontal posture. During the downward movement, the inclined surfaces of the guide plates 10 on both sides limit the movement of the cylindrical materials, so that the movement trajectory of the cylindrical materials is continuously constrained, thereby reducing the probability of tumbling, swaying, and posture confusion. When it is necessary to adapt to cylindrical materials of different specifications, the bidirectional lead screw 15 can drive the traction frame 14 and the guide plate 10 to move closer or further away synchronously to adjust the restricted guiding space between the guide plates 10. The adjustment knob 11 can also drive the gear 17 to move along the rack 16, so that the first adjustment frame 7, the attitude conversion slide 5 and the guide plate 10 move as a whole. At the same time, through the cooperation of the traction rod 20, traction hole 21, traction seat 19, traction ring 18, drive plate 23, guide block 25 and guide groove 24, multiple adjustment plates 22 are driven to move radially synchronously, so as to realize the linkage between the change of the inner diameter of the material handling port 8 and the change of the alignment of the inlet of the attitude conversion slide 5. After the cylindrical material is discharged through the attitude conversion slide 5, it comes into contact with the buffer roller 28. The buffer roller 28 decelerates the material and stabilizes it. Then the material enters the conveying device 4 and is continued to be transported to the subsequent work station.

[0041] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
