Description

Technical Field

[0001] The present invention relates to the technical field of product processing, and particularly to a material conveying device and an air box head processing device. Background Art

[0002] A thermal expansion valve generally includes a valve body, a valve core, a transmission rod and an air box head. The air box head generally includes an air box seat, an air box cover, and a material clamped between the air box cover and the air box seat. Generally, the two sides of the material have different structures. During the processing of the air box head, there are mainly two ways to feed the material: one is manual feeding by workers, which has high labor intensity and low production efficiency for workers. Moreover, accurate positioning cannot be achieved, and angle deviation is likely to occur; the other is to use a vibrating disk for feeding, but there are problems such as material overlap resulting in multiple materials being output at one time and the material being placed in reverse, and the quality of the discharged material is low. Summary of the Invention

[0003] The purpose of the present invention is to provide a material conveying device that can improve the quality of discharged materials.

[0004] Another purpose of the present invention is to provide an air box head processing device provided with the material conveying device.

[0005] To achieve the above purpose, the present invention provides a material conveying device that can be used to convey thin sheet products, including a controller, an inner turntable, an outer turntable, a screening mechanism and a retaining ring. At least part of the inner turntable is located radially outside the outer turntable, and at least part of the retaining ring is located radially outside the outer turntable; the retaining ring includes a first baffle and a discharging part. Along the vertical direction of the conveying device, at least part of the first baffle is located above the outer turntable; along the rotation direction of the conveying device, the first baffle is located upstream of the discharging part, and a screening mechanism is arranged between the first baffle and the discharging part. The screening mechanism includes a blowing device and a detection device. The gas path extension direction of the blowing device faces the inner turntable, and the detection device and the blowing device are electrically connected to the controller.

[0006] The material conveying device provided by the present invention is mainly composed of a controller, an inner turntable, an outer turntable, a screening mechanism and a retaining ring, etc. During operation, the materials are placed on the inner turntable disorderly. The inner turntable rotates rapidly. Under the action of centrifugal force, the materials are transferred from the high points on the inner turntable to the transfer surface at the upper end of the outer turntable along the field. During this process, the first baffle first screens out abnormal products through height screening, arranges the disorderly products in order, prevents material overlap, and facilitates subsequent automatic feeding and assembly; by arranging a screening mechanism between the first baffle and the discharging part, the detection device can identify the materials with the reverse side facing up, and the blowing device can blow the materials with the reverse side facing up into the inner turntable, so as to achieve the purpose of discharging the materials with the front side facing up.

Detailed implementation manners

[0017] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0018] In this text, terms such as "upper, lower, inner, outer" are established based on the positional relationship shown in the drawings. Depending on the different drawings, the corresponding positional relationship may also change accordingly. Therefore, it cannot be understood as an absolute limitation of the protection scope. Moreover, relational terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any such actual relationship or order between these components.

[0019] Please refer to Figure 1 、 Figure 2 、 Figure 3 , Figure 1 which is a schematic structural diagram of a material conveying device provided by an embodiment of the present invention; Figure 2 is Figure 1 a top view of the material conveying device shown; Figure 3 is Figure 1 a side view of the material conveying device shown.

[0020] As shown in the figure, in a specific embodiment, the material conveying device provided by the present invention mainly consists of an inner turntable 10, an outer turntable 20, a retaining ring 30, a first baffle 41, a screening mechanism 50, a second baffle 42, a cutting wheel assembly 60, and other parts.

[0021] The inner turntable 10 is located radially outside the outer turntable 20. At least part of the retaining ring 30 is located radially outside the outer turntable 20. The surface of the inner turntable 10 is provided with evenly distributed and radially extending material guiding ribs 11, and these material guiding ribs 11 together form a material guiding assembly. The central axis of the inner turntable 10 is installed at an inclined angle with respect to the central axis of the outer turntable 20, and its highest point is smoothly and transitionally connected to the annular transmission surface 21 at the top of the outer turntable 20. That is to say, the material 100 can smoothly slide from the highest point of the inner turntable 10 to the annular transmission surface 21 of the outer turntable 20 under the action of centrifugal force, and the lowest point of the inner turntable 10 is lower than the annular transmission surface 21 of the outer turntable 20.

[0022] The retaining ring 30 is provided with a first baffle 41 and a discharge part 31. The retaining ring 30 is located at the outer peripheral part of the annular transmission surface 21 and is higher than the annular transmission surface 21 by a certain distance. The retaining ring 30 is provided with a discharge part 31 at the position corresponding to the low point of the inner turntable 10, that is, on the other side corresponding to the highest point of the inner turntable 10.

[0023] Along the vertical direction of the conveying device, at least part of the first baffle 41 is located above the outer turntable 20; along the rotation direction of the conveying device, the first baffle 41 is located upstream of the discharge part 31. A screening mechanism 50 is arranged between the first baffle 41 and the discharge part 31. The screening mechanism 50 has a blowing device 51 and a detection device 52. The gas path extension direction of the blowing device 51 faces the inner turntable, and the detection device 52 and the blowing device 51 are electrically connected to the controller.

[0024] The air blowing device 51 is provided with an air blowing main body 511 and an air guiding part 512. The air guiding part 512 has an extension section 5121 and a nozzle section 5122. The air blowing main body 511 is located radially outside the outer turntable 20. The extension section 5121 connects the air blowing main body 511 and the nozzle section 5122. The extension direction of the nozzle section 5122 forms an acute angle with the plane where the upper end face of the outer turntable 20 is located.

[0025] The conveying channel is located on the upper end face of the outer turntable 20. Let the equivalent radius of the material 100 be a, and the channel width of the conveying channel is at least b between the first baffle 41 and the discharging part 31. Then a < b < 2a. Vertically, at least part of the nozzle section is located above the outer turntable 20.

[0026] In this way, when blowing air, the material 100 can be blown off, so that the material 100 realizes automatic flipping during the falling process, and finally achieves the technical effect that all the materials 100 face upwards. Moreover, the included angle between the outlet direction of the nozzle section and the end face of the outer turntable 20 is set to be acute, and the material 100 can be gathered towards the middle by the blowing force, improving the feeding efficiency and the correct rate of flipping.

[0027] The first baffle 41 is fixedly connected to the retaining ring 30. The first baffle 41 at least partially overhangs above the outer turntable 20. A first material passing channel is formed between the lower end face of the first baffle 41 and the outer turntable 20. The axial height of the first material passing channel is H, and the maximum height of a single material 100 is h. Then h < H < 2h, that is, the first material passing channel only allows a single material 100 to pass through, so as to achieve the purpose of screening the material 100.

[0028] The first baffle 41 has a first end and a second end. The first end is fixedly connected to the retaining ring 30. The second end is arranged opposite to the first end. The projection of the second end on the outer turntable 20 along the vertical direction of the conveying device is close to the inner turntable 10. The second end is located downstream of the first end along the rotation direction of the conveying device.

[0029] In this way, when the outer turntable 20 drives the material 100 to rotate, the material 100 can gradually enter the first material passing channel instead of passing through the first material passing channel at one time. This can not only prolong the time for the material 100 to pass through the first material passing channel, making the screening more accurate, but also enable the materials 100 that do not meet the screening conditions to fall back to the inner turntable 10 along the first baffle 41 without accumulating at the position where the first baffle 41 is located.

[0030] The discharging part 31 is provided with a second baffle 42 and a discharging port 311. A second material passing channel is formed between the second baffle 42 and the inner side wall of the retaining ring 30. The discharging port 311 is located at the end of the second material passing channel. The radial width of the second material passing channel is D, and the maximum diameter of a single material is d. Wherein, d < D < 2d, only a single material 100 is allowed to pass through.

[0031] The second baffle 42 has a third end and a fourth end. The fourth end is fixedly connected to the retaining ring 30. The third end at least partially overhangs above the inner turntable 10. The third end is located upstream of the fourth end along the rotation direction of the conveying device.

[0032] In order to better guide the material 100 into the second material passing channel, one end of the second baffle 42 facing the material 100 is bent outward in an arc shape, so that the inlet of the second material passing channel is in an open flared shape.

[0033] Specifically, the first baffle 41 is installed on the inner wall of the retaining ring 30 through a connecting block 32 at the top of the retaining ring 30. A longitudinal oblong hole is opened on the first baffle 41 and can be connected to the connecting block 32 through a screw. The height H of the first material passing channel can be adjusted through the oblong hole, so as to be applicable to materials 100 of different thicknesses, or to make fine adjustments when there are errors.

[0034] The detection device 52 is installed on the inner wall of the retaining ring 30 and is close to the annular transmission surface 21, and is used to identify the front and back states of the material 100. When an abnormal surface is identified, the air guiding part 512 can be controlled to blow air to blow the material 100 into the inner turntable 10. When a normal state surface is identified, the air guiding part 512 stops blowing air, and the material 100 passes through normally.

[0035] Specifically, the detection device 52 can be a photoelectric sensor or a proximity sensor. It is arranged on the inner wall of the retaining ring 30 and is close to the annular transmission surface 21, and performs detection along the radial direction of the retaining ring 30.

[0036] Since there are differences in the structures of the front and back sides of the material 100, when the material 100 passes through the detection device 52 in the posture of facing up and facing down, the detection signals of the detection device 52 will be different, so as to obtain two different detection signals. One of the detection signals represents that the material 100 is facing up, and the other detection signal represents that the material 100 is facing down. By distinguishing different detection signals, the purpose of identifying the front state of the material 100 can be achieved.

[0037] A control valve is provided on the air path of the air blowing device 51. The control valve is electrically connected to the controller. After receiving the detection signal of the detection device 52, the controller processes the signal. When the set condition is reached, the controller outputs an instruction to the control valve to make the control valve open and blow air from the air outlet of the air blowing device 51.

[0038] The discharging section 31 is also provided with a cutting wheel assembly 60. The cutting wheel assembly 60 is located between the second baffle 42 and the outer turntable 20 along the vertical direction of the conveying device. The bottom of the second baffle 42 includes an avoidance opening for avoiding the cutting wheel assembly 60. The cutting wheel assembly 60 is located at the end of the second material passing channel along the rotating direction of the conveying device. The cutting wheel assembly 60 includes a cutting wheel 61 that can rotate towards the outer turntable 20. A plurality of cutting grooves 611 are circumferentially and evenly distributed on the outermost side of the cutting wheel 61. At least one side of the cutting groove 611 is tangent to the side wall of the second material passing channel.

[0039] The diameter of the cutting groove 611 is equal to the diameter of the material 100. The material 100 can be embedded in the cutting groove 611. During the rotation of the cutting wheel 61, the material 100 is sequentially output along the tangential direction through the cutting groove 611.

[0040] Please also refer to Figure 4 、 Figure 5 , Figure 4 For Figure 3 the A-A view of the material conveying device shown; Figure 5 For Figure 2 the B-B view of the material conveying device shown.

[0041] As shown in the figure, on the bottom plate 80 of the entire conveying device, a guide wheel assembly 90 is provided to support the inner turntable 10 and the outer turntable 20 for rotation.

[0042] A positioning ring platform 22 is provided at the bottom of the outer turntable 20. The guide wheel assembly 90 mainly consists of an upper positioning wheel 91, a lower positioning wheel 92, an inner side positioning wheel 93, and an outer side positioning wheel 94, etc. The upper positioning wheel 91, the lower positioning wheel 92, the inner side positioning wheel 93, and the outer side positioning wheel 94 are respectively installed on the base 80 through vertical brackets. Among them, the upper positioning wheel 91 is in rolling contact with the upper end surface of the positioning ring platform 22, and the lower positioning wheel 92 is in rolling contact with the lower end surface of the positioning ring platform 22. The upper positioning wheel 91 and the lower positioning wheel 92 clamp the outer turntable 20 from top and bottom to perform axial limit on the outer turntable 20.

[0043] The inner side positioning wheel 93 and the outer side positioning wheel 94 are arranged in the lateral position. The inner side positioning wheel 93 is in rolling contact with the inner peripheral surface of the positioning ring platform 22, and the outer side positioning wheel 94 is in rolling contact with the outer peripheral surface of the positioning ring platform 22.

[0044] During assembly, the guide wheel assembly clamps the outer turntable 20, and then through the corresponding assembly of the inner side wall of the outer turntable 20 and the outer side wall of the inner turntable 10, the inner turntable 10 and the outer turntable 20 are assembled and positioned through a tooling positioning bracket. A plurality of positioning wheels are provided and are circumferentially and evenly distributed.

[0045] The working principle of the above-mentioned material conveying device is as follows:

[0046] First, put the material 100 into the inner turntable 10. The inner turntable 10 and the outer ring transfer plate 20 convey the product through rotation. Since the inner turntable 10 is inclined, and there are evenly distributed material guiding ribs 11 on its upper surface, the material starts to be evenly conveyed outward under the action of the material guiding.

[0047] Under the action of centrifugal force, the material 100 is smoothly transferred from the inner turntable 10 to the outer turntable 20 at the position where the highest point of the inner turntable is connected to the annular transfer surface 21 of the outer turntable 20.

[0048] The material 100 is conveyed along the circumferential direction on the annular transfer surface 21. When passing through the first baffle 41, the first baffle 41 will filter out the overlapping and warped materials 100. When passing through the screening mechanism 50, the blowing device 51 will conduct a secondary screening and blow the materials 100 that do not meet the requirements into the inner turntable 10, and then the second baffle 42 will guide the material 100 into the cutting wheel assembly 60.

[0049] After the material 100 rotates to the cutting wheel assembly 60 on the outer ring, the cutting wheel assembly 60 outputs the material 100 piece by piece by using the rotation of the outer ring.

[0050] The materials 100 that do not meet the requirements after screening will re-adjust their position states through the material guiding ribs 11 and, under the action of centrifugal force, are transferred back to the outer turntable 20 through the inner turntable 10 again. After being screened again, they are sent out by the cutting wheel assembly 60 to ensure the accuracy rate of the sent materials and improve the assembly efficiency.

[0051] The above embodiments are only the preferred solutions of the present invention, and are not specifically limited thereto. On this basis, targeted adjustments can be made according to actual needs to obtain different implementation manners. For example, the top of the material guiding rib 11 is arc-shaped, and the inner end is designed as an inclined surface to avoid scratching the material, or the blowing direction of the blowing device 51 is perpendicular to the material 100, etc. Since there are many possible implementation manners, they will not be listed one by one here.

[0052] The material conveying device provided by the present invention, through the cooperation of the inner turntable 10 and the outer turntable 20, arranges the disordered materials 100 in order, and undergoes multiple screenings during the conveying process. The first baffle 41 screens abnormal materials 100 through height, the blowing mechanism 50 screens abnormal materials 100 by detecting the front and back through the detection device 52, and at the same time blows the abnormal materials 100 back to the inner turntable 10 for re-circulation. The second baffle 42 can screen and send out the normal materials 100, and finally the materials 100 are automatically discharged to a fixed position one by one, facilitating subsequent automatic feeding and assembly. Since it relies on the rotation and centrifugal method for conveying, it has advantages such as low noise and high speed.

[0053] Please continue to refer to Figure 6 、 Figure 7 、 Figure 8, Figure 6 is Figure 1 a schematic structural view of the material conveying device shown after removing the base and the retaining ring; Figure 7 is a schematic transmission structure view of the retaining ring and the material cutting wheel assembly; Figure 8 is a schematic structural view of the power drive assembly.

[0054] As shown in the figure, in addition to the above-mentioned material conveying device, the present invention also provides a gas tank head processing device, which is provided with the material conveying device described above, and is provided with a first driving motor 95 and a second driving motor 96. The output end of the first driving motor 95 is drivingly connected to the inner turntable 10, and the output end of the second driving motor 96 is connected with a transmission assembly, and the transmission assembly is at least partially connected to the guide wheel assembly 90 to drive the outer turntable 20 and the material cutting wheel assembly 60.

[0055] The first driving motor 95 directly drives the inner turntable 10 to rotate, and the second driving motor 96 is used to drive one of the inner positioning wheels 93, and then indirectly drives the outer turntable 20 through the inner positioning wheel 93. The diameter of the inner positioning wheel 93 for transmission is larger than the diameters of other inner positioning wheels to have sufficient contact area for transmission.

[0056] In this embodiment, a guiding slide rail 70 for horizontal translation is provided between the output shaft of the second driving motor 96 and one of the inner positioning wheels 93. Through horizontal translation, the inner positioning wheel 93 can be brought into contact with the inner peripheral surface of the outer turntable 20 so as to transmit power to each other.

[0057] The rotating shaft of the material cutting wheel assembly 60 is drivingly connected to one of the outer positioning wheels 94 through a transmission wheel 62. In this way, when the outer turntable 20 rotates, the material cutting wheel 61 can be indirectly driven to rotate through the outer positioning wheel 94 and the transmission wheel 62, so that there is no need to separately provide a driving motor for the material cutting wheel assembly 60, reducing the number of parts and simplifying the structure.

[0058] The above has introduced in detail the material conveying device and the gas tank head processing device provided by the present invention. Specific examples are used herein to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the core idea of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
