Description

Technical Field

[0001] This invention relates to the field of air conditioner manufacturing technology, and more specifically, to a feeding device and a loading equipment having the same. Background Technology

[0002] Currently, in the production process of air conditioner evaporators and condensers, a small U-shaped elbow needs to be inserted into the copper tubes of both the evaporator and the condenser. Each of the two copper tubes of the small U-shaped elbow has a welding ring. After the small U-shaped elbow is inserted into the condenser and evaporator, the pre-processed condenser and evaporator are transported to the welding station to melt the welding rings, and then the small U-shaped elbow, the copper tubes of the evaporator and the copper tubes of the condenser are welded together to ensure the airtightness of the connection between the two.

[0003] In the existing technology, for the above processing steps, the feeding process of the small U-shaped elbow actually adopts the form of vibration feeding throughout the entire process. That is, the small U-shaped elbow needs to rely on the vibration action of the vibrating plate to complete the conveying of the small U-shaped elbow from the feeding plate to the distributing plate.

[0004] However, the vibratory feeding method has the following two problems:

[0005] 1. Poor uniformity of feeding cycle: During the vibratory feeding process, the small U-shaped elbow needs to move gradually by relying on vibration. Its moving speed, that is, the time required for it to be transported from the feeding tray to the distributing tray, cannot be accurately controlled. Especially when the layout of the processing production line causes the small U-shaped elbow to be transported over a long distance, the small U-shaped elbow is also prone to jamming. The feeding time will produce a larger error. At this time, the subsequent production equipment can only wait for the small U-shaped elbow to be loaded into place before it can continue to operate, which affects the overall processing efficiency of the production line.

[0006] 2. The feeding position is not very accurate. The feeding position of the vibratory feeding system cannot be precisely controlled. It can only rely on the sensor to detect whether the corresponding size of the small U-shaped bend at the preset position has reached the preset size to determine whether the small U-shaped bend has been fed in place. However, if there is a processing error in the small U-shaped bend, it will cause the sensor to misjudge. If the distributing plate then takes corresponding actions, it will cause damage to the small U-shaped bend, or even damage to the structure of the distributing plate itself. Summary of the Invention

[0007] The main objective of this invention is to provide a feeding device and a feeding equipment having the same, so as to solve the problems of poor feeding cycle uniformity and feeding position accuracy of the small U-shaped bend of the air conditioner in the prior art.

[0008] To achieve the above objectives, according to one aspect of the present invention, a feeding device is provided, disposed on a feeding device and located between a feeding device and a distributing device, for conveying material from the feeding device to the distributing device. The feeding device includes: a material channel structure having a feeding channel for receiving material; and a feeding assembly movably disposed along the extension direction of the feeding channel, the feeding assembly including a feeding structure having a limiting recess; wherein the feeding structure is vertically movably disposed and has a feeding position and a clearance position; when the feeding structure is in the feeding position, the limiting recess limits and stops at least a portion of the material along the extension direction of the feeding channel, and the feeding assembly drives the material to move through the limiting stop between the limiting recess and the material to perform feeding; when the feeding structure moves to the clearance position, the feeding structure avoids the material along the extension direction of the feeding channel.

[0009] Furthermore, the material channel structure includes: a material channel body having a first material channel and an installation notch communicating with the first material channel; and a feeding component having a second material channel; wherein the feeding component is movably disposed at the installation notch and has a feeding position and a receiving position. When the feeding component is in the receiving position, the second material channel is connected to the outlet of the feeding device to receive the material discharged by the feeding device; when the feeding component moves to the feeding position, the second material channel is connected to the first material channel to form a feeding channel.

[0010] Furthermore, there are multiple limiting recesses, which are spaced apart along the extension direction of the feeding channel; wherein, when the feeding structure is in the feeding position, at least one limiting recess is a material limiting stop located in the second material channel, so as to pick up the material in the second material channel during the process of the feeding component driving the material to move.

[0011] Furthermore, the feeding structure is provided with a notch that penetrates the feeding structure, and the inner wall of the notch forms a limiting recess; wherein the shape of the limiting recess matches the shape of at least part of the outer peripheral surface of the material.

[0012] Furthermore, the feeding structure is plate-shaped, and the extension direction of the feeding structure is consistent with the extension direction of the feeding channel. The multiple limiting recesses include multiple feeding recesses and discharge recesses. The discharge recesses are located near the distributing device relative to the feeding recesses. The discharge recesses extend to the side of the feeding structure near the distributing device to form a discharge opening on that side.

[0013] Furthermore, the depth of the feeding channel is greater than or equal to the height of the material; the feeding structure is plate-shaped, and the extension direction of the feeding structure is consistent with the extension direction of the feeding channel; wherein, the feeding structure between two adjacent limiting recesses forms an insertion part, and when the feeding structure is in the feeding position, at least part of the insertion part is inserted into the feeding channel.

[0014] Furthermore, the feeding assembly also includes a first driving member, which is driven to the feeding structure to drive the feeding structure to perform lifting and lowering movements; the feeding device also includes a second driving member, which is driven to the first driving member to drive the first driving member to move the feeding structure along the extension direction of the feeding channel.

[0015] Furthermore, at least a portion of the outer surface of the feeding component forms a sealing surface, which blocks the outlet of the feeding device when the feeding component moves to the feeding position; and / or, the feeding device further includes a third driving component, which is drivenly connected to the feeding component and is used to drive the feeding component to move between the feeding position and the receiving position; and / or, the feeding device further includes a sealing component located on the side of the feeding component away from the feeding device, which blocks the end of the second material channel away from the feeding device when the feeding component is in the receiving position.

[0016] Furthermore, the material channel body includes: a bottom plate; and side plates disposed on the bottom plate, wherein there are at least two side plates, which are arranged opposite to each other to form a first material channel; wherein each side plate has a mounting recess that penetrates the side plate on the side away from the bottom plate, so as to form a mounting notch between the inner wall of the at least two mounting recesses and the upper surface of the bottom plate.

[0017] According to another aspect of the present invention, a feeding device is provided, which includes a feeding device, a conveying device and a distributing device. The conveying device is located between the feeding device and the distributing device, and is used to convey the material conveyed to the conveying device via the feeding device to the distributing device; wherein the conveying device is the aforementioned conveying device.

[0018] According to the technical solution of the present invention, a feeding device is disposed on a feeding device and located between a feeding device and a distributing device, for conveying material from the feeding device to the distributing device. The feeding device has a feeding channel structure for accommodating material. A feeding component is movably disposed along the extension direction of the feeding channel. The feeding component includes a feeding structure with a limiting recess. The feeding structure is vertically movably disposed and has a feeding position and a clearance position. When the feeding structure is in the feeding position, the limiting recess limits and stops at least a portion of the material along the extension direction of the feeding channel. The feeding component drives the material to move through the limiting stop between the limiting recess and the material to perform feeding. When the feeding structure moves to the clearance position, the feeding structure avoids the material along the extension direction of the feeding channel. In this way, for material conveying between the feeding device and the distributing device, this application completely eliminates the traditional vibration conveying method. When the feeding structure moves to the feeding position, the limiting recess of the feeding structure and the limiting stop between the material allow the feeding component to push the material in the feeding channel to the corresponding loading position in one go, achieving high loading position accuracy. Simultaneously, when the feeding structure moves to the avoidance position, the feeding component can reset without interfering with the material. Through the cooperation between the feeding component (whole) and the feeding structure (partial), uninterrupted material conveying (approximately step-by-step conveying) can be achieved. The operator only needs to adjust the movement speed of the feeding component and the feeding structure to obtain a stable feeding rhythm, thus solving the problems of poor uniformity of the loading rhythm and poor loading position accuracy in the existing technology for small U-shaped bends in air conditioners.

[0040] To address the issues of poor uniformity of feeding cycle and poor accuracy of feeding position in existing air conditioner U-shaped bends, this application provides a feeding device and a feeding equipment having the same.

[0041] like Figures 1 to 7 As shown, a feeding device is installed on a feeding equipment and located between the feeding device 1 and the distributing device 2, for conveying material 3 from the feeding device 1 to the distributing device 2. The feeding device includes: a material channel structure 10 having a feeding channel 11 for accommodating material 3; and a feeding assembly 20 movably arranged along the extension direction of the feeding channel 11. The feeding assembly 20 includes a feeding structure 21 having a limiting recess 211. The feeding structure 21 is vertically movably arranged and has a feeding position and a clearance position. When the feeding structure 21 is in the feeding position, the limiting recess 211 limits and stops at least part of the material 3 along the extension direction of the feeding channel 11. The feeding assembly 20 drives the material 3 to move through the limiting stop between the limiting recess 211 and the material 3 to perform feeding. When the feeding structure 21 moves to the clearance position, the feeding structure 21 avoids the material 3 along the extension direction of the feeding channel 11.

[0042] Applying the technical solution of this embodiment, the feeding device is disposed on the feeding equipment and located between the feeding device 1 and the distributing device 2, for conveying the material 3 on the feeding device 1 to the distributing device 2. The material channel structure 10 of the feeding device has a feeding channel 11 for accommodating the material 3. The feeding component 20 is movably disposed along the extension direction of the feeding channel 11. The feeding component 20 includes a feeding structure 21 with a limiting recess 211. The feeding structure 21 is vertically movably disposed and has a feeding position and a clearance position. When the feeding structure 21 is in the feeding position, the limiting recess 211 limits and stops at least part of the material 3 along the extension direction of the feeding channel 11. The feeding component 20 drives the material 3 to move through the limiting stop between the limiting recess 211 and the material 3 to perform feeding. When the feeding structure 21 moves to the clearance position, the feeding structure 21 avoids the material 3 along the extension direction of the feeding channel 11. In this way, for the material conveying between the feeding device 1 and the distributing device 2, this embodiment completely eliminates the traditional vibration conveying method. That is, when the feeding structure 21 moves to the feeding position, the limiting recess 211 of the feeding structure 21 and the limiting stop between the material 3 allow the feeding component 20 to push the material 3 located in the feeding channel 11 to the corresponding feeding position in one go, which has high feeding position accuracy. At the same time, when the feeding structure moves to the avoidance position, the feeding component 20 can also perform a reset movement without interfering with the material 3. Through the mutual cooperation between the feeding component 20 (whole) and the feeding structure 21 (part), the uninterrupted conveying of the material 3 can be achieved (approximately step-by-step conveying). The operator only needs to adjust the movement speed of the feeding component 20 and the feeding structure 21 to obtain a stable feeding rhythm, thereby solving the problems of poor feeding rhythm uniformity and feeding position accuracy of the small U-shaped bend of the air conditioner in the prior art.

[0043] In this embodiment, the feeding device is set on the frame of the loading equipment. The operator can also set up a separate frame for the feeding device according to actual needs to realize the modular design of the feeding device, which facilitates the connection between the feeding device and other processing devices in the automated production line, thereby improving the versatility of the feeding device.

[0044] In this embodiment, material 3 is a small U-shaped elbow used in the process of connecting the two components (evaporator and condenser) of an air conditioner.

[0045] like Figures 3 to 7 As shown, to facilitate observation of the cooperation between the feeding structure 21 and the material 3, Figure 3 A portion of the material channel structure 10 (side plate 124 of the material channel body 12) was disassembled to expose the material 3 located in the feeding channel 11. Figures 4 to 7 The feeding process of the feeding component 20 is then displayed sequentially. Figure 4This means that the feeding assembly 20 has moved to its initial position and the feeding structure 21 has risen to the avoidance position. Figure 5 The feeding structure 21 descends to the feeding position, and the material 3 enters into the limiting recess 211 and is stopped by the inner wall of the limiting recess 211. Figure 6 The central feeding assembly 20 moves as a whole to move the material 3, thereby conveying the material 3 to the loading position. Figure 7 The feeding structure 21 rises again to the avoidance position, and the feeding assembly 20 prepares to move to... Figure 5 At the position, to repeat Figures 5 to 7 The feeding process enables the repetitive conveying of material 3.

[0046] like Figures 1 to 3 As shown, the material channel structure 10 includes: a material channel body 12, having a first material channel 121 and an installation notch 122 communicating with the first material channel 121; and a feeding component 13, having a second material channel 131. The feeding component 13 is movably disposed at the installation notch 122 and has a feeding position and a receiving position. When the feeding component 13 is in the receiving position, the second material channel 131 communicates with the outlet 101 of the feeding device 1 to receive the material 3 discharged by the feeding device 1. When the feeding component 13 moves to the feeding position, the second material channel 131 communicates with the first material channel 121 to form a feeding channel 11. Thus, the feeding component 13 enables a fixed amount of material to be fed between the feeding device 1 and the feeding device (material channel structure 10), preventing excessive material 3 from accumulating in the feeding channel 11, thereby improving the feeding stability of the feeding device.

[0047] Specifically, when the feeding component 13 is in the receiving position, the second material channel 131 is connected to the discharge port 101 of the feeding device 1 to receive the material 3 discharged by the feeding device 1. When the feeding component 13 moves to the feeding position, the second material channel 131 is connected to the first material channel 121 to form the feeding channel 11, that is, the material 3 is fed into the material channel structure 10 at this time.

[0048] like Figure 1 As shown, the loading component 13 is now in the loading position, and its second material channel 131 and the first material channel 121 of the material channel body 12 are connected to each other to form a connected feeding channel 11 and complete the loading.

[0049] like Figure 3 As shown, the feeding component 13 is now in the receiving position, and its second material channel 131 is connected to the discharge port 101 of the feeding device 1 to receive the material 3 discharged through the discharge port 101.

[0050] Optionally, there are multiple limiting recesses 211, which are spaced apart along the extending direction of the feeding channel 11. When the feeding structure 21 is in the feeding position, at least one limiting recess 211 stops and restrains the material 3 located in the second material channel 131, thereby picking up the material 3 in the second material channel 131 as the feeding assembly 20 moves the material 3. This arrangement ensures that while the feeding assembly 20 moves the material 3 in the feeding channel 11 via the feeding structure 21 to convey the material, the feeding structure 21 can also move the material 3 located in the second material channel 131, thus enabling it to pick up newly fed material 3 into the material channel structure 10.

[0051] In this embodiment, there are eight limiting recesses 211, which are spaced apart along the extension direction of the feeding channel 11 to synchronously convey eight materials 3 in the feeding channel 11.

[0052] It should be noted that the number of limiting recesses 211 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, there may be two, three, four, five, six, or more limiting recesses 211.

[0053] like Figure 1 and Figure 3 As shown, the feeding structure 21 has a notch that penetrates through the feeding structure 21, and the inner wall of the notch forms a limiting recess 211. The shape of the limiting recess 211 matches the shape of at least a portion of the outer peripheral surface of the material 3. This arrangement simplifies the formation of the limiting recess 211 and increases the mating area between the inner wall of the limiting recess 211 and the material 3, thereby improving the reliability of their fit.

[0054] In this embodiment, the limiting recess 211 is a semi-circular recess, and its semi-circular inner wall matches the arc-shaped outer surface of the small U-shaped bend.

[0055] like Figure 1 and Figure 3As shown, the feeding structure 21 is plate-shaped, and its extension direction is consistent with that of the feeding channel 11. Multiple limiting recesses 211 include multiple feeding recesses 212 and discharge recesses 213. The discharge recesses 213 are positioned relative to the feeding recesses 212 and closer to the distributing device 2. The discharge recesses 213 extend to the side of the feeding structure 21 near the distributing device 2, forming a discharge opening 214 on this side. Thus, during the movement and feeding process of the feeding assembly 20, the material located in the discharge recesses 213 will move into the distributing device 2. The discharge opening 214, on the one hand, avoids interference between the feeding structure 21 and the distributing device 2; on the other hand, it ensures that the material 3 enters the distributing device 2 quickly and reliably, thereby improving the feeding stability of the feeding structure 21.

[0056] In this embodiment, the feeding structure 21 is generally plate-shaped and located on the side of the feeding channel 11. It is vertically arranged and the extension direction of the plate-shaped structure is consistent with the extension direction of the feeding channel 11. The feeding structure 21 has a notch extending to its lower surface. The notch has a travel limiting recess 211. Among the multiple limiting recesses 211, the limiting recess 211 located near the distributing device 2 is the feeding recess 212. The feeding recess 212 extends to both the lower surface of the feeding structure 21 and the surface near the distributing device 2, so as to form a discharge opening 214 on the side of the feeding structure 21 near the distributing device 2. The feeding recess 212 can communicate with the distributing device 2 through the discharge opening 214, so that the material 3 located in the feeding recess 212 can move directly into the distributing device 2.

[0057] like Figure 1 , Figure 3 and Figure 5 As shown, the depth of the feeding channel 11 is greater than or equal to the height of the material 3; the feeding structure 21 is plate-shaped, and the extension direction of the feeding structure 21 is consistent with the extension direction of the feeding channel 11; wherein, the feeding structure 21 between two adjacent limiting recesses 211 forms an insertion part 215, and when the feeding structure 21 is in the feeding position, at least a portion of the insertion part 215 is inserted into the feeding channel 11. In this way, the above arrangement allows the feeding channel 11 to fully accommodate the material 3, thereby improving its reliability in accommodating the material 3; on the other hand, the arrangement of the insertion part 215 allows the feeding structure 21 to partially extend into the feeding channel 11, further increasing the contact area between the feeding structure 21 and the material 3. At the same time, when the material 3 located in the feeding channel 11 gets stuck between itself and the inner wall of the feeding channel 11, the insertion part 215 can also promptly push the material 3 to move, thereby further improving the smoothness of the material 3's movement.

[0058] like Figure 1 and Figure 3As shown, the feeding assembly 20 further includes a first driving member 22, which is drivenly connected to the feeding structure 21 to drive the feeding structure 21 to perform lifting and lowering movements. The feeding device also includes a second driving member 30, which is drivenly connected to the first driving member 22 to drive the first driving member 22 to move the feeding structure 21 along the extension direction of the feeding channel 11. In this way, the above configuration achieves automated movement of the feeding structure 21 through the first driving member 22 and automated movement of the feeding assembly 20 through the second driving member 30.

[0059] Optionally, the first driving component 22 is a driving cylinder (such as an air cylinder), and the second driving component 30 is a driving cylinder (such as an air cylinder).

[0060] Specifically, the drive cylinder has a faster response speed and more precise stroke, which helps to improve the uniformity of the feeding cycle and the accuracy of the feeding position of material 3. At the same time, the operator can also adjust the feeding cycle (i.e., the time taken to complete the entire feeding process of one material 3) by controlling the drive speed of the drive cylinder to match subsequent processing requirements.

[0061] like Figure 10 As shown, at least a portion of the outer surface of the feeding component 13 forms a sealing surface 132. When the feeding component 13 moves to the feeding position, the sealing surface 132 blocks the discharge port 101 of the feeding device 1. In this way, when the feeding component 13 moves to the feeding position to feed the material 3, its outer surface (sealing surface 132) can also block the discharge port 101 of the feeding device 1 to prevent the material 3 from falling.

[0062] In this embodiment, the feeding component 13 is a block structure with grooves machined on it to form a second material channel 131.

[0063] Specifically, a flared opening is machined on one end of the second material channel 131 near the feeding device 1. The flared opening reduces the difficulty for the material 3 discharged through the discharge port 101 to enter the second material channel 131.

[0064] like Figure 1 and Figure 3As shown, the feeding device further includes: a third driving member 40, which is drivenly connected to the feeding member 13, and the third driving member 40 is used to drive the feeding member 13 to move between the feeding position and the receiving position; and / or, a blocking member 50, located on the side of the feeding member 13 away from the feeding device 1, which blocks the end of the second material channel 131 away from the feeding device 1 when the feeding member 13 is in the receiving position. In this way, the above configuration realizes the automated movement of the feeding member 13 through the third driving member 40; the blocking member 50 can block the end of the second material channel 131 away from the feeding device 1 when the feeding member 13 is in the receiving position, so as to prevent the material entering the second material channel 131 from continuing to move under inertia and falling.

[0065] In this embodiment, the sealing element 50 is block-shaped.

[0066] like Figure 1 , Figure 3 and Figure 4 As shown, the material channel body 12 includes: a base plate 123; and side plates 124 disposed on the base plate 123. There are at least two side plates 124, which are arranged opposite each other to form a first material channel 121. Each side plate 124 has a mounting recess 125 penetrating the side plate 124 on its side away from the base plate 123, forming a mounting notch 122 between the inner walls of the at least two mounting recesses 125 and the upper surface of the base plate 123. This arrangement simplifies the structure of the material channel body 12 and the formation of the mounting notch 122, making it easier to manufacture and reducing the manufacturing cost and difficulty for workers.

[0067] In this embodiment, there are two side plates 124, which are disposed on the bottom plate 123 and arranged opposite to each other, so as to form a first material channel 121 by surrounding the two side plates 124 facing each other and the bottom plate 123.

[0068] In this embodiment, the first material channel 121 located on the side of the installation notch 122 away from the feeding component 13 is provided with an enlarged diameter end 1211 (flared mouth) near the end of the feeding component 13, so as to reduce the difficulty of the material 3 entering the first material channel 121 from the second material channel 131, avoid the material 3 getting stuck, and ensure that the material 3 can be smoothly conveyed.

[0069] like Figures 8 to 10 As shown, this embodiment also provides a feeding device, which includes a feeding device 1, a conveying device, and a distributing device 2. The conveying device is located between the feeding device 1 and the distributing device 2, and is used to convey the material 3 that is conveyed from the feeding device 1 to the conveying device to the distributing device 2. The conveying device is the aforementioned conveying device.

[0070] In this embodiment, the feeding device 1 is a vibrating feeding plate, which has a relatively conventional structure and will not be described in detail here.

[0071] In this embodiment, the material distribution device 2 includes a material distribution disk 201 and a drive structure 203. The drive structure 203 drives the material distribution disk 201 to rotate. The material distribution disk 201 is provided with a plurality of material troughs 202. One end of each material trough 202 extends to the outer peripheral surface of the material distribution disk 201 to form a feed inlet. The material distribution disk 201 is also provided with a limiting member 204 located at the material trough 202. The limiting member 204 includes two limiting structures arranged opposite to each other. The two limiting structures are arranged opposite to each other to form a limiting space. During the feeding process of the feeding component 20 of the feeding device, the feeding structure 21 actually feeds the material 3 into the material trough 202. That is, the material distribution plate 201 will rotate to the position where the inlet of the material trough 202 is opposite to the end of the feeding channel 11. When the feeding structure 21 moves to the corresponding position, the material 3 in its feeding recess 212 moves into the material trough 202 through the inlet. After the material enters the material trough 202, it will move into the limiting space to maintain its posture through the limiting member 204. When the material trough 202 is finished being filled, the feeding structure 21 rises to the avoidance position, the feeding component 20 resets, and the material distribution plate 201 rotates to the position where the inlet of the next material trough 202 is opposite to the end of the feeding channel 11 to fill the next material trough 202.

[0072] Specifically, in the traditional vibratory feeding process, it is impossible to accurately control whether the material 3 has moved into the trough 202. Only by setting a sensor, such as a distance sensor, on the distribution plate 201 can the distance between the material 3 and the detection end be detected. When the distance reaches a preset value, it is determined that the material 3 has entered the trough 202. However, if the material 3 has processing errors or is a defective part, the detection result of the distance sensor will be invalid. At this time, it is easy for the material 3 to not be fully entered into the trough 202 before the distribution plate 201 starts to rotate. The material 3 will jam the rotation of the distribution plate 201, and may even cause damage to the distribution device 2. However, the feeding device in this embodiment can completely avoid the above problems. That is, when the control module controls the first drive component 22 and the second drive component 30 to move into place, it can ensure that the material 3 is fed into place, and then control the rotation of the distribution plate 201. There is no need to set up a sensor, which reduces the processing cost of the distribution device 2.

[0073] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0074] A feeding device is installed on a feeding equipment and located between a feeding device and a distributing device to transport materials from the feeding device to the distributing device. The feeding device has a material channel structure for receiving materials. A feeding assembly is movably arranged along the extension direction of the feeding channel. The feeding assembly includes a feeding structure with a limiting recess. The feeding structure is vertically movably arranged and has a feeding position and a clearance position. When the feeding structure is in the feeding position, the limiting recess limits and stops at least a portion of the material along the extension direction of the feeding channel. The feeding assembly drives the material to move through the limiting stop between the limiting recess and the material to feed it. When the feeding structure moves to the clearance position, the feeding structure avoids the material along the extension direction of the feeding channel. In this way, for material conveying between the feeding device and the distributing device, this application completely eliminates the traditional vibration conveying method. When the feeding structure moves to the feeding position, the limiting recess of the feeding structure and the limiting stop between the material allow the feeding component to push the material in the feeding channel to the corresponding loading position in one go, achieving high loading position accuracy. Simultaneously, when the feeding structure moves to the avoidance position, the feeding component can reset without interfering with the material. Through the cooperation between the feeding component (whole) and the feeding structure (partial), uninterrupted material conveying (approximately step-by-step conveying) can be achieved. The operator only needs to adjust the movement speed of the feeding component and the feeding structure to obtain a stable feeding rhythm, thus solving the problems of poor uniformity of the loading rhythm and poor loading position accuracy in the existing technology for small U-shaped bends in air conditioners.
