Description

Technical Field

[0001] The present invention relates to a vibration turnover machine and a shot blasting device. Background Art

[0002] In industrial production, many workpieces need to be subjected to treatments such as metal surface sand removal, rust removal, and strengthening. When performing on-line surface treatment on flat-shaped workpieces in large quantities, it is necessary to accurately turn over the workpieces. For shot blasting of flat castings in large quantities, they are usually turned over and shot blasted only by means of rotation, swinging, etc. This results in high processing costs, long time consumption, and labor intensiveness. For example, in a suspension type shot blasting machine, generally, workers place the workpieces on a spreader pulled by a suspension chain or directly hang them on a hanging basket with a hook. The spreader or the hanging basket advances while rotating itself through each processing station so that the surfaces of all workpieces can be treated. Finally, the treated workpieces still have to be taken off the hanging basket manually. Another example is a swing bed type shot blasting machine and a crawler type shot blasting machine. Through the swinging or rotation of the shot blasting device, the workpieces are freely and disorderly turned over. Therefore, it takes longer time and more cost to clean the workpieces thoroughly. Therefore, how to solve the accurate turning over of workpieces and complete the workpiece surface treatment task with a simple and efficient method has become an urgent task to be solved.

[0003] First, through Figure 1 the shown method, directly conveyed by a vibrating bed, the workpieces are turned over by the way of free fall. However, this method cannot ensure the accurate turning over of the workpieces after falling, and at the same time, the free fall will cause corresponding damage to the workpieces.

[0004] Another one is through Figure 2 the shown method. On the basis of free fall, vertical baffles are added, and through the restraint of the vertical baffles, the workpieces are restrained to turn over. Although there are restraint baffles compared with the above unconstrained method, which can make some workpieces achieve the turning-over action, workpieces of different sizes are limited by the distance from the baffle to the outlet of the vibrating bed and the difficulty in adjusting the falling height, and still cannot achieve accurate turning over. Summary of the Invention

[0005] Aiming at the above technical problems, the purpose of the present invention is to provide a vibration turnover machine and a shot blasting device that can realize the turning-over action of workpieces online and in batches and are applicable to large-scale shot blasting production.

[0006] The technical solution to realize the present invention is as follows

[0007] Vibration turnover machine, including a vibrating bed, a turnover channel is arranged at the end or side of the vibrating bed. The turnover channel includes a turnover part with a sliding surface on the inner side. Under the action of gravity, one end of the workpiece sent from the vibrating bed contacts the sliding surface, slides down along the sliding surface to guide the upper surface of the workpiece to flip and lean against the sliding surface, and slides along the sliding surface to the lower part of the sliding surface, so that the upper surface of the workpiece is flipped to the lower side, realizing the flipping action of the workpiece.

[0008] When the turnover channel is at the end of the vibrating bed, the turnover channel is arranged outside the discharge port of the vibrating bed, and the inner side of the turnover part faces the discharge port of the vibrating bed; the front end of the workpiece contacts the inner side of the turnover part to form a first fulcrum, and the rear end of the workpiece forms a second fulcrum on the vibrating bed; during the forward movement of the workpiece, the front end of the workpiece slides down along the sliding surface. When the center of gravity of the workpiece deviates towards the turnover part, the rear end of the workpiece separates from the vibrating bed, and the upper surface of the workpiece leans against the inner side of the turnover part and slides along the inner side to the lower part of the sliding surface, so that the upper surface of the workpiece is flipped to the lower side, realizing the flipping action of the workpiece.

[0009] When the turnover channel is on the side of the vibrating bed, the turnover part is arranged in the vibrating bed, and the arrangement direction of the inner side of the turnover part is the same as the feeding direction of the vibrating bed; a feeding backrest is arranged in the vibrating bed, the turnover part is below the feeding backrest, and the end of the turnover part extends towards the side of the feeding backrest, and the turnover channel is formed between the feeding backrest and the inner side of the turnover part; a gradually changing channel with an opening gradually increasing is formed between the side edge of the feeding backrest and the inner side of the turnover part along the feeding direction; when the workpiece enters the turnover channel in an inclined state, the upper end of the workpiece contacts the outer side of the feeding backrest to form a first fulcrum, and the lower end of the workpiece contacts the inner side of the turnover part to form a second fulcrum; during the forward movement of the workpiece, the lower end of the workpiece slides down along the sliding surface. As the gradually changing channel gradually increases, the center of gravity of the workpiece gradually shifts towards the turnover part. When the center of gravity of the workpiece shifts to the side of the turnover part, the upper surface of the workpiece leans against the inner side of the turnover part and slides along the inner side to the lower part of the sliding surface, so that the upper surface of the workpiece is flipped to the lower side, realizing the flipping action of the workpiece.

[0010] A first guiding area and a second guiding area are arranged in the vibrating bed. The workpieces entering the vibrating bed pass through the first guiding area and the second guiding area in sequence and enter the turnover channel at an increasingly larger vertical angle.

[0011] The first guiding area includes a first inclined slide plate and a first side inclined plate arranged at an angle with the first inclined slide plate. A first guiding channel is formed between the first inclined slide plate and the first side inclined plate;

[0012] The second guiding area includes a second inclined slide plate and a second side inclined plate arranged at an angle with the second inclined slide plate. A second guiding channel is formed between the second inclined slide plate and the second side inclined plate;

[0013] The inner side surface of the first inclined plate is not lower than the inner side surface of the second inclined plate;

[0014] The inclination angle of the first inclined slide plate is smaller than the inclination angle of the second inclined slide plate.

[0015] An included angle of 90° or more than 90° is formed between the first inclined slide plate and the first inclined plate; an included angle of 90° or more than 90° is formed between the second inclined slide plate and the second inclined plate.

[0016] The height of the outer side surface of the feeding backrest is not higher than the inner side surface of the second inclined plate, and the inner side surface of the turning part is not higher than the inner side surface of the second inclined slide plate;

[0017] Below the feeding backrest is a blanking space for the workpieces after being turned over through the gradual change channel to slide in; for the workpieces entering the turning channel from the second guiding area, the lower ends of the workpieces slide downward along the sliding curved surface. As the gradual change channel gradually increases, the center of gravity of the workpieces gradually shifts towards the turning part. When the center of gravity of the workpieces shifts to the side of the turning part, the upper surface of the workpieces abuts against the inner side surface of the turning part and slides downward along the inner side surface to the lower part of the sliding curved surface, so that the upper surface of the workpieces is turned to the lower side and enters the blanking space.

[0018] The feeding backrest is arranged in the middle of the vibrating bed, and the feeding backrest is arranged along the feeding direction of the vibrating bed. Turning channels are respectively arranged on both sides of the feeding backrest.

[0019] The turning part is U-shaped, the feeding backrest is inverted U-shaped, and the feeding backrest is arranged above the middle inside the turning part in a suspended state.

[0020] A shot blasting device, including an upper shot blasting machine and a lower shot blasting machine, and the above-mentioned vibrating turning machine is arranged between the two-stage shot blasting machines; the material receiving end of the vibrating turning machine is butted against the discharge port of the upper shot blasting machine, and the material discharging end of the vibrating turning machine is butted against the feeding port of the lower shot blasting machine. After the workpieces discharged from the upper shot blasting machine are turned over by the vibrating turning machine, they are sent into the lower shot blasting machine.

[0021] With the above technical solution, a flipping channel is provided at the end or side of the vibrating bed. The flipping channel includes a flipping part with a sliding surface on its inner side. Under the action of gravity, one end of the workpiece sent from the vibrating bed contacts the sliding surface and slides down along the sliding surface, so as to guide the upper surface of the workpiece to slide down to the lower part of the sliding surface, turning the upper surface of the workpiece downward and realizing the flipping action of the workpiece. Through the setting of the flipping part, the sliding surface on the inner side of the flipping part enables the workpiece conveyed by the vibrating bed to form a downward sliding action when one end of the workpiece contacts the inner side of the flipping part. Under the guidance of gravity and the sliding surface, when the center of gravity of the workpiece deviates towards the flipping part, the workpiece forms a flip towards the flipping part, and the upper surface of the workpiece slides down along the inner side of the flipping part, finally turning the upper surface of the workpiece downward and realizing the turning-over action of the workpiece, thereby ensuring that the workpiece can achieve the turning-over action. During the use of the present invention, the vibration of the vibrating bed provides the forward force for the workpiece. The workpieces enter the flipping channel in sequence and are automatically flipped without the need for manual operation, reducing the labor cost and labor intensity, and improving the production efficiency. It is suitable for on-line, batch and large-scale production work. The research and development of the flipping machine in this application provides a vibration flipping machine that is economical (with reasonable, simple structure, few required components and low manufacturing cost), efficient (able to work on-line, short process, batch continuous flipping), and accurate (able to ensure that each workpiece realizes the turning-over action), solving the problem of accurate on-line flipping of workpieces and being applicable to application occasions such as shot blasting equipment.

Detailed implementation manner

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0037] Please refer to Figure 3-13As shown in the figure, the vibrating turning machine 100 includes a vibrating bed 101 that generates vibration to provide a conveying force. One end of the vibrating bed 101 is a material receiving end, and the other end is a material discharging end. A frame 102 is provided below the vibrating bed 101 to form a support. A spring 103 is provided at the support between the frame 102 and the vibrating bed 101. A vibrating motor 104 is installed outside the vibrating bed 101. When the vibrating motor 104 generates vibration, through the buffering of the spring 103, the vibrating bed 101 generates a continuous conveying force on the workpiece entering the vibrating bed 101. A turning channel 105 is provided at the end or side of the vibrating bed 101. The turning channel 105 includes a turning part 106 with a sliding surface on the inner side. Under the action of gravity, one end of the workpiece sent from the vibrating bed 101 contacts the sliding surface and slides down along the sliding surface to guide the upper surface of the workpiece 107 to slide along the sliding surface to the lower part of the sliding surface, so that the upper surface of the workpiece is turned to the lower part, realizing the turning action of the workpiece. Through the setting of the turning part 106, the sliding surface on the inner side of the turning part 106, the workpiece conveyed by the vibrating bed 101 vibrates. One end of the workpiece forms contact with the inner side of the turning part 106 to form a downward sliding action. Through the guidance of gravity and the sliding surface, when the center of gravity of the workpiece is biased towards the turning part 106, the workpiece forms a turn towards the turning part 106. The upper surface of the workpiece adheres to the inner side of the turning part 106 and slides down along the inner side, and finally the upper surface of the workpiece is turned to the lower part, realizing the turning action of the workpiece, so as to ensure that the workpiece can realize the turning action.

[0038] Embodiment 1: Refer to Figure 3 As shown in the figure, when the turning channel 105 is at the end of the vibrating bed 101, the turning channel 105 is arranged outside the material discharging port of the vibrating bed 101, and the inner side of the turning part 106 faces the material discharging port of the vibrating bed 101 directly; the workpiece sent by the vibrating bed 101 directly contacts the turning part 106. The front end of the workpiece contacts the inner side of the turning part 106 to form a first fulcrum, and the rear end of the workpiece forms a second fulcrum on the vibrating bed 101; during the forward movement of the workpiece, the front end of the workpiece slides down along the sliding surface. When the center of gravity of the workpiece is biased towards the turning part 106, the rear end of the workpiece separates from the vibrating bed 101, and the upper surface of the workpiece leans against the inner side of the turning part 106 and slides down along the inner side to the lower part of the sliding surface, so that the upper surface of the workpiece is turned to the lower part, realizing the turning action of the workpiece. As Figure 3As shown, the a end of the workpiece contacts the inner side surface of the flipping part 106 first. Under the action of gravity and the sliding surface, the a end of the workpiece continues to slide downward, causing the center of gravity of the workpiece to shift towards the flipping part 106. Then the workpiece will flip towards the flipping part 106. The upper surface of the workpiece fits the sliding surface and slides downward. The a end of the workpiece moves down to the a1 state, and the b end of the workpiece moves down to the b1 state. Thus, the workpiece can achieve a turning-over action. During the turning-over process, when the center of gravity of the workpiece does not shift towards the flipping part 106, the a end of the workpiece does not separate from the vibrating bed 101 to ensure there are corresponding fulcrums. The flipping part 106 can have an inclined end that slopes outward from above and a curved surface section below. The flipping part 106 is generally arc-shaped, and at least an arc-shaped sliding surface is formed on the inner side surface of the flipping part 106.

[0039] Embodiment 2: Refer to Figure 3-11 As shown, when the flipping channel 105 is at the side of the vibrating bed 101, the flipping part 106 is arranged in the vibrating bed 101. The arrangement direction of the inner side surface of the flipping part 106 is the same as the feeding direction of the vibrating bed 101. A feeding ridge 108 is arranged in the vibrating bed 101. The flipping part 106 is below the feeding ridge 108, and the end of the flipping part 106 extends towards the side surface of the feeding ridge 108. The flipping channel 105 is formed between the feeding ridge 108 and the inner side surface of the flipping part 106. A gradually changing channel 109 with an opening gradually increasing is formed between the side edge of the feeding ridge 108 and the inner side surface of the flipping part 106 along the feeding direction. In this arrangement, when the workpiece enters the flipping channel 105 in an inclined state, the upper end of the workpiece contacts the outer side of the feeding ridge 108 to form a first fulcrum, and the lower end of the workpiece contacts the inner side surface of the flipping part 106 to form a second fulcrum. During the forward movement of the workpiece, the lower end of the workpiece slides downward along the sliding surface. As the gradually changing channel 109 gradually increases, the center of gravity of the workpiece gradually shifts towards the flipping part 106. When the center of gravity of the workpiece shifts to the side of the flipping part 106, the upper surface of the workpiece leans against the inner side surface of the flipping part 106 and slides along the inner side surface towards the lower part of the sliding surface, turning the upper surface of the workpiece to the lower side to achieve the turning-over action of the workpiece.

[0040] One way in this embodiment: A receiving plate 110 is arranged at the receiving end of the vibrating bed 101 for receiving the workpiece to be turned over, and a discharging plate 111 is arranged at the discharging end of the vibrating bed 101 for sending out the turned-over workpiece. The vibrating bed 101 has a multi-step shape with a gradually decreasing height from the receiving plate 110 to the discharging plate 111, so that the workpiece is smoothly conveyed step by step from the receiving plate 110 to the discharging plate 111. The height of the receiving plate 110 is higher than the inside of the vibrating bed 101 to facilitate feeding the received workpiece into the vibrating bed 101. The height of the discharging plate 111 is lower than the tail of the vibrating bed 101 to facilitate the workpiece in the vibrating bed 101 to enter the discharging plate 111.

[0041] One way in this embodiment: A first guiding area 112 and a second guiding area 113 are provided in the vibrating bed 101. The workpieces entering the vibrating bed 101 pass through the first guiding area 112 and the second guiding area 113 in sequence and enter the flipping channel 105 at an increasingly larger vertical angle. The first guiding area 112 and the second guiding area 113 are generally V-shaped. The height of the first guiding area 112 inside the vibrating bed 101 is higher than the height of the second guiding area 113 inside the vibrating bed 101, which is convenient for the workpieces in the first guiding area 112 to enter the second guiding area 113. The number of guiding areas can be selected and set according to needs. Two guiding areas are shown in the attached drawings of this application.

[0042] One way in this embodiment: The first guiding area 112 includes a first inclined slide plate 114 and a first side inclined plate 115 arranged at an angle with the first inclined slide plate 114. A first guiding channel is formed between the first inclined slide plate 114 and the first side inclined plate 115; the second guiding area 113 includes a second inclined slide plate 116 and a second side inclined plate 117 arranged at an angle with the second inclined slide plate 116. A second guiding channel is formed between the second inclined slide plate 116 and the second side inclined plate 117; the inner side surface of the first side inclined plate 115 is not lower than the inner side surface of the second side inclined plate 117; the downward inclination angle of the first inclined slide plate 114 is smaller than the downward inclination angle of the second inclined slide plate 116. When the workpiece enters the first guiding channel, the workpiece moves forward along the first inclined slide plate 114, and the inclination angle of the workpiece is the same as the inclination angle of the first inclined slide plate 114. When entering the second guiding area 113, the workpiece is conveyed forward along the second inclined slide plate 116, and the inclination angle of the workpiece becomes the inclination angle of the second inclined slide plate 116. If it is necessary to maintain this inclination angle when outputting from the vibrating bed 101, the discharge plate 111 can be set to have the same inclination angle as the second guiding area 113 to make the workpiece maintain this inclination angle and be sent out; during the conveying process, since the inner side surfaces of the first side inclined plate 115 and the second side inclined plate 117 are flush, it will not hinder the forward movement of the workpiece.

[0043] One way in this embodiment: An angle of 90° or more than 90° is formed between the first inclined slide plate 114 and the first side inclined plate 115; an angle of 90° or more than 90° is formed between the second inclined slide plate 116 and the second side inclined plate 117. Increasing the bottom angle of the guiding area can avoid the problem that the lower end of the workpiece is stuck at the bottom of the guiding area due to too small an angle.

[0044] One way in this embodiment: the outer side height of the feeding back 108 is not higher than the inner side of the second side inclined plate, and the inner side of the flipping part 106 is not higher than the inner side of the second inclined sliding plate; below the feeding back 108 is a discharging space 118 for the workpiece after being flipped through the gradual change channel 109 to slide in; for the workpiece entering the flipping channel 105 from the second guiding area 113, the lower end of the workpiece slides downward along the sliding surface, and as the gradual change channel 109 gradually increases, the center of gravity of the workpiece gradually shifts towards the flipping part 106. When the center of gravity of the workpiece shifts to the side of the flipping part 106, the upper surface of the workpiece abuts against the inner side of the flipping part 106 and slides along the inner side towards the lower part of the sliding surface, so that the upper surface of the workpiece is flipped to the lower side and enters the discharging space 118.

[0045] One way in this embodiment: the feeding back 108 is arranged in the middle of the vibrating bed 101, and the feeding back 108 is arranged along the feeding direction of the vibrating bed 101, and flipping channels 105 are respectively arranged on both sides of the feeding back 108. The height of the back is kept consistent from the material receiving end to the material discharging end, and the overall height of the back should exceed the height of the workpiece to be flipped when it is in the flipping channel 105 to prevent the workpiece from climbing over to the adjacent flipping channel 105. When one flipping channel 105 is set, the workpiece to be flipped sequentially enters the flipping channel 105 for flipping and conveying actions; when multiple flipping channels 105 are set, the workpieces to be flipped on the receiving plate 110 alternately enter each flipping channel 105, and the workpieces in each flipping channel 105 do not interfere with each other. Finally, the flipped workpieces are sent out from the discharging plate 111. The setting of multiple flipping channels 105 is more suitable for online batch production work.

[0046] One way in this embodiment: the flipping part 106 is U-shaped, the feeding back 108 is inverted U-shaped, and the feeding back 108 is arranged above the middle inside the flipping part 106 in a suspended state, and a discharging space 118 is formed between the lower part of the feeding back 108 and the lower part of the flipping part 106.

[0047] Next, specifically describe the flipping machine with two flipping channels 105 shown in the drawings of the second embodiment of the present application: the frame 102, the spring 103, the vibrating bed 101, and the vibrating motor 104 constitute a complete vibrating conveyor, which can make the workpieces on the trough vibrate forward, and there are no protrusions blocking the forward movement of the workpieces in the forward direction of the workpieces on the vibrating bed 101.

[0048] The receiving plate 110 receives the workpieces to be flipped conveyed from the previous equipment and makes the workpieces move forward flatly.

[0049] The inside of the vibrating bed 101 is symmetric about the back line 119 of the feeding back 108 on the left and right sides.

[0050] The first guiding area 112 is formed by bending a whole plate. The two first inclined sliding plates in the middle and the two first side inclined plates on the left and right together form a W shape. The highest point is the back ridge line 119, and the height of the back ridge line 119 is flush with the material receiving plate 110. The first inclined sliding plate is bent downward along the back ridge line 119 with two slopes, namely an included angle a and an included angle b. The lowest point is perpendicular to the corresponding first side inclined plate. The included angle between the first inclined sliding plate and the vertical plane is b, and the angle of the included angle a is less than the angle of the included angle b.

[0051] The second guiding area 113 is formed by bending a whole plate. The two second inclined sliding plates and the two second side inclined plates on the left and right together form a W shape. The highest point is the back ridge line 119, and the height of the back ridge line 119 is flush with the material receiving plate 110. The second inclined sliding plate is bent downward along the back ridge line 119 with two slopes, namely an included angle a and an included angle c. The included angle c is greater than the included angle b. The lowest point is perpendicular to the second side inclined plate. The second side inclined plate has the same slope as the first side inclined plate, and the height of the high point is the same as that of the first side inclined plate. After the lower edge is bent, it is perpendicular to the second inclined sliding plate.

[0052] The flipping part 106 is formed by bending a whole plate into a U shape. The height of the high point on the inner side of the flipping part 106 is the same as that of the second side inclined plate. The bottom of the U-shaped plate is used to hold and convey the flipped workpiece. The feeding back ridge 108 is formed by bending a whole plate into an inverted U shape. The highest point is the back ridge line 119. It is bent downward along the back ridge line 119 with two slopes, namely an included angle a and an included angle c. The lowermost part has a slope so that the vertical distance between the lower edge and the U-shaped plate is suitable for the size of the flipped workpiece. The discharging plate 111 is flush with the bottom surface of the flipping part 106 to ensure that the flipped workpiece is output flat.

[0053] Please refer to Figure 12When the flat workpiece from the front-end equipment enters the turning machine, the bottom surface of the workpiece contacts the receiving plate 110, and it moves forward under the vibration conveying action of the turning machine, and is spread out without overlapping. The workpiece moves forward to the next step, enters the W-shaped section formed by the first inclined slide plate and the first side inclined slide plate, and moves forward along the ridge line 119 into two left and right channels. The bottom surface of the workpiece contacts the first inclined slide plate, and the workpiece tilts due to the inclination of the first inclined slide plate, and the outer side surface contacts the first side inclined slide plate. The workpiece continues to move forward, continues to the next step, and enters the deep W-shaped section formed by the second inclined slide plate and the second side inclined slide plate. The bottom surface of the workpiece contacts the second inclined slide plate, and the workpiece further tilts due to the inclination of the second inclined slide plate, and the outer side surface contacts the second side inclined slide plate. The workpiece continues to move forward and enters the section formed by the U-shaped flipping part 106 and the inverted U-shaped feeding ridge 108. The bottom surface of the workpiece contacts the outside of the inverted U-shaped feeding ridge 108. For example, the d end of the workpiece is at the top and the c end of the workpiece is at the bottom. The bottom of the c end of the workpiece enters the gradual channel 109 formed by the U-shaped flipping part 106 and the inverted U-shaped feeding ridge 108. As the distance between the lower edge of the inverted U-shaped feeding ridge 108 and the U-shaped flipping part 106 becomes larger and larger, finally, under the action of gravity and the sliding surface slope of the inner side of the U-shaped flipping part 106, the c end of the workpiece slides to the c1 state, and the d end of the workpiece flips to the d1 state, thereby realizing the flipping action of the workpiece. After flipping, the original upper surface of the workpiece is attached to the inner side of the U-shaped flipping part 106 and slides into the bottom of the U-shaped flipping part 106, becoming the lower surface, and the flipping is completed; the flipped workpiece is transported forward by vibration into the discharge plate 111 to be leveled, and then enters the next equipment for processing from the outlet.

[0054] See also Figure 13 , a continuous shot blasting device with a turning channel 105 arranged on the side of the turning machine is adopted, including an upper shot blasting machine 120 and a lower shot blasting machine 121, and the above-mentioned vibration turning machine 100 is arranged between the two shot blasting machines; the receiving end of the vibration turning machine 100 is connected to the discharge port of the upper shot blasting machine, and the discharge end of the vibration turning machine 100 is connected to the feed port of the lower shot blasting machine. The workpiece discharged from the upper shot blasting machine is turned over by the vibration turning machine 100 and sent to the lower shot blasting machine. The upper shot blasting machine performs shot blasting on the upper surface of the workpiece. After the upper surface shot blasting is completed, the workpiece is sent to the vibration turning machine 100, and the workpiece is turned over by the vibration turning machine 100, so that the upper surface of the workpiece is turned over to the bottom, and the lower surface of the workpiece becomes the upper surface, and then it is sent to the lower shot blasting machine for shot blasting. In this way, the double-sided shot blasting of the workpiece can be realized in an online continuous manner, which improves the work efficiency and ensures the shot blasting quality.

Under the action of gravity, one end of the workpiece sent from the vibrating bed contacts the sliding surface and slides downward along the sliding surface to guide the upper surface of the workpiece to turn and lean against the sliding surface, and then slides along the sliding surface to the lower part of the sliding surface, turning the upper surface of the workpiece to the lower side to realize the turning action of the workpiece. The turning part is arranged in the vibrating bed, and the arrangement direction of the inner side surface of the turning part is the same as the feeding direction of the vibrating bed. A feeding ridge is arranged in the vibrating bed. The turning part is located below the feeding ridge, and the end of the turning part extends towards the side of the feeding ridge. The turning channel is formed between the feeding ridge and the inner side surface of the turning part. A gradually changing channel with an increasingly larger opening is formed along the feeding direction between the side edge of the feeding ridge and the inner side surface of the turning part. When the workpiece enters the turning channel in an inclined state, the upper end of the workpiece contacts the outer side of the feeding ridge to form a first fulcrum, and the lower end of the workpiece contacts the inner side surface of the turning part to form a second fulcrum. During the forward movement of the workpiece, the lower end of the workpiece slides downward along the sliding surface. As the gradually changing channel gradually enlarges, the center of gravity of the workpiece gradually shifts towards the turning part. When the center of gravity of the workpiece shifts to the side of the turning part, the upper surface of the workpiece leans against the inner side surface of the turning part and slides along the inner side surface to the lower part of the sliding surface, turning the upper surface of the workpiece to the lower side to realize the turning action of the workpiece. The height of the outer side surface of the feeding ridge is not higher than the inner side surface of the second side inclined plate, and the inner side surface of the turning part is not higher than the inner side surface of the second inclined slide plate. Below the feeding ridge is a discharging space for the workpiece to slide into after being turned through the gradually changing channel. For the workpiece entering the turning channel from the second guiding area, the lower end of the workpiece slides downward along the sliding surface. As the gradually changing channel gradually enlarges, the center of gravity of the workpiece gradually shifts towards the turning part. When the center of gravity of the workpiece shifts to the side of the turning part, the upper surface of the workpiece leans against the inner side surface of the turning part and slides along the inner side surface to the lower part of the sliding surface, turning the upper surface of the workpiece to the lower side and entering the discharging space. The feeding ridge is arranged in the middle of the vibrating bed and extends along the feeding direction of the vibrating bed. Turning channels are respectively arranged on both sides of the feeding ridge. The turning part is U-shaped, and the feeding ridge is inverted U-shaped. The feeding ridge is arranged above the middle of the turning part in a suspended state.
