[0001] The present application relates to the field of heat exchanger manufacturing, and in particular to a material cutting mechanism and a material cutting method thereof. Background Art
[0002] In the heat exchanger, some parts include a plate-like part and a flange part. The flange part is located on the periphery of the plate-like part, and the flange part and the plate-like part are set at a certain angle. Such a structure makes it easy for the plate-like parts to be tightly connected and difficult to separate during the stacking process, resulting in the failure to discharge the material according to the predetermined quantity each time, resulting in the final stacked product being unqualified. Summary of the invention
[0003] The purpose of this application is to provide a material unloading mechanism that can effectively improve the accuracy of the material unloading quantity.
[0004] A material unloading mechanism provided in the present application includes a material bin, a clamping mechanism and a separation mechanism. The material bin includes a feed end and a discharge end. Along the vertical direction, the clamping mechanism and the separation mechanism are located between the feed end and the discharge end. In the horizontal direction, the clamping mechanism is located on opposite sides of the material bin, and the separation mechanism includes a pushing piece. The plate-like piece unloading mechanism includes a material shifting state. In the material shifting state, the pushing piece moves toward one side of the discharge end, and the pushing piece pushes at least one plate-like piece.
[0005] The present application sets a separation mechanism between the feed end and the discharge end of the silo, and separates the material not clamped by the clamping mechanism from the material above it through a pushing piece, thereby effectively improving the accuracy of the material discharge quantity and improving the qualified rate of the final stacked products.

[0019] The following is a detailed description of the plate-like member unloading equipment in the embodiment of the present application in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can complement or combine with each other. The "vertical direction" in this embodiment refers to the direction perpendicular to the horizontal plane, which can also be understood as the stacking direction of the plate-like members.
[0020] The following is combined with Figures 1 to 8 Some embodiments are described in detail.
[0021] like Figure 1 , Figure 2 and Figure 3 The unloading mechanism 100 includes a silo 1 and a supporting mechanism 2. The silo 1 includes a feed end 11 and a discharge end 12. When the equipment is in operation, the feed end 11 is located above the discharge end 12. The material enters the silo 1 from the feed end 11 and is output from the discharge port 121 of the discharge end 12 by its own gravity. The supporting mechanism 2 is located at the lower end of the silo 1. Specifically, relative to the feed end 11, the supporting mechanism 2 is arranged close to the discharge end 12. Further, the supporting mechanism 2 includes a supporting member 21. The supporting member 21 is arranged close to the discharge end 12, and the supporting member 21 can at least partially block the discharge port 121. Specifically, the silo 1 is arranged along the vertical direction, and the materials in the silo are stacked along the vertical direction. The supporting member 21 is located below the discharge end 12, and the supporting member 21 includes a supporting surface 211. The plane where the supporting surface 211 is located intersects with the vertical direction. In some embodiments, the plane where the supporting surface 211 is located is perpendicular to the vertical direction. The supporting member 21 can reciprocate between a position close to the discharge port 121 and a position away from the discharge port 121. When close to the discharge port 121, the supporting member 21 can support the material at the discharge port 121. Specifically, the supporting surface 211 contacts the material at the lower end; when away from the discharge port 121, the discharge port 121 is open, and at least the material at the lower end of the discharge port 121 falls from the discharge port 121 due to the lack of support from the supporting member 21, thereby realizing the unloading action.
[0022] Some heat exchangers are made of multiple plate-like parts stacked together. Some plate-like parts generally include a plate-like part and a flange part. The flange part is located at the periphery of the plate-like part. The angle between the flange part and the plate-like part is an obtuse angle. After the plate-like parts are stacked, part of the flange part is blocked, but the outer wall of the upper half of the flange part is exposed. This structure makes it easy for the plate-like parts to be tightly connected and difficult to separate during the stacking process due to the gravity generated by the upper plate-like parts. In order to ensure that only a specified number of plate-like parts fall when unloading, such as Figures 1 to 5 The unloading mechanism 100 is provided with a clamping mechanism 3 and a separating mechanism 4, such as Figure 1 and Figure 4, along the vertical direction, the separation mechanism 4 is located between the supporting mechanism 2 and the feed end 11, and the separation mechanism 4 includes a pusher 41. When the unloading mechanism 100 is in the material-discharging state, the pusher 41 can reciprocate between approaching and moving away from the clamping member; specifically, the pusher 41 is arranged close to the clamping member, and the movement direction of the pusher 41 intersects with the horizontal plane, that is, the pusher 41 can reciprocate in the vertical direction, or reciprocate in the inclined direction at an acute angle to the horizontal plane. Further, the extension direction of the flange part on the same side as the pusher 41 is the same as or close to the movement direction of the pusher 41. The pusher 41 pushes against the flange part and continues to move a predetermined distance to the side of the discharge port, so that the pusher 41 peels off the plate-like member that is not clamped by the clamping member and drops it. Combined with the movement of the supporting mechanism 2, it is achieved that at least one plate-like member is peeled off from the stacked material and output from the discharge port 121 each time the discharge port 121 is opened.
[0023] like Figure 1 , Figure 2 or Figure 3 , along the vertical direction, the clamping mechanism 3 is located between the supporting mechanism 2 and the feed end 11, the clamping mechanism 3 includes a first clamping member 31 and a second clamping member 33, along the horizontal direction, the first clamping member 31 and the second clamping member 33 are located on both sides of the silo 1, the first clamping member 31 and the second clamping member 33 can approach or move away from the silo 1 at the same time, when the first clamping member 31 and the second clamping member 33 are close to the silo, the first clamping member 31 and the second clamping member 33 abut against part of the plate-like member, specifically, the first clamping member 31 and the second clamping member 33 abut against part of the flanged portion of the plate-like member, thereby clamping at least part of the plate-like member located in the silo 1; further, the clamping mechanism 3 includes a first power mechanism 32, such as a cylinder, an electric push rod, a hydraulic cylinder, etc., the first power mechanism 32 can drive the first clamping member 31 and the second clamping member 33 Move closer to or away from the silo 1. Furthermore, a clamping surface 311 is provided on the side of the first clamping member 31 and / or the second clamping member 33 close to the silo 1. When the first power mechanism 32 drives the first clamping member 31 and / or the second clamping member 33 to move closer to the silo 1 until the clamping surface 311 abuts against the plate-like members stacked in the silo, the first power mechanism 32 can provide a thrust toward the silo 1 to the clamping surface 311, so that the clamping surface 311 clamps the plate-like members stacked in the silo 1, and the clamped plate-like members and other plate-like members stacked above the plate-like members will not fall out of the discharge port 121 due to the support member 21 moving away from the discharge port 121. That is, combined with the design of the support member 21 moving back and forth between approaching and moving away from the discharge port 121, it can be achieved that only a predetermined number of plate-like members are output from the discharge port 121 each time the discharge port 121 is opened.
[0024] like Figure 6The supporting mechanism 2 includes a second power mechanism 22, such as a cylinder, an electric push rod, a hydraulic cylinder, etc. The second power mechanism 22 can drive the supporting member 21 to approach or move away from the discharge port 121. In some embodiments, the second power mechanism 22 enables the supporting member 21 to reciprocate in the horizontal direction. Of course, the second power mechanism 22 can also enable the supporting member 21 to move along the stacking direction of the plate-like members. For example, one end of the supporting member 21 is fixed to the silo 1, and the other end is driven by the second power mechanism 22 to approach or move away from the discharge port 121, that is, the supporting member 21 flips with one end as the fixed axis, thereby opening or closing the discharge port 121.
[0025] like Figure 2 and Figure 8 The unloading mechanism 100 includes two symmetrically arranged supporting mechanisms 2 and 2'. Specifically, along the horizontal direction, the two supporting mechanisms 2 are respectively located on opposite sides of the silo 1. Driven by the second power mechanism 22, the two relatively arranged supporting members 21 and 21' can simultaneously approach or move away from the discharge port 121. When the two supporting members 21 and 21' simultaneously approach the discharge port 121, the plate-like member located above the discharge port 121 is lifted by the two supporting members 21 and 21'. When the two supporting members 21 and 21' simultaneously move away from the discharge port 121, the discharge port 121 is opened, and a part of the plate-like member located in the silo 1 falls out of the discharge port 121. Further, as Figure 3 The supporting member 21 includes a main body 212, and a receiving surface 211 is located at the main body 212, that is, the receiving surface 211 is a part of the side of the main body 212 facing the material. In some embodiments, the receiving surface 211 is formed by a surface of part of the main body 212 facing the material side being recessed toward the side away from the material, that is, the main body 212 includes a step portion 216, and the step portion 216 includes a step surface 2161, and at least a part of the step surface 2161 is the receiving surface 211, which is used to contact the lower surface of the plate-like member and thereby lift the plate-like member.
[0026] like Figure 6 and Figure 8 Furthermore, the supporting member 21 includes a first guide portion 213 and a second guide portion 214, and the first guide portion 213 and the second guide portion 214 are fixedly arranged on one side of the main body 212, or the first guide portion 213, the second guide portion 214 and the main body 212 are integrated; accordingly, the plate-like member unloading mechanism 100 includes a base plate 5, and the base plate 5 includes a third guide portion 51, and the third guide portion 51 extends in a horizontal direction. The third guide portion 51 and the first guide portion 213 or the second guide portion 214 are slidably matched, so that the supporting member 21 can move backward in the horizontal direction.
[0027] like Figure 5 and Figure 7Further, the supporting member 21 includes a limiting portion 215, the limiting portion 215 and the main body 212 are an integral part, or the limiting portion 215 is fixedly connected to the main body 212, the limiting portion 215 is arranged on the side of the main body 212 facing the material, and the limiting portion 215 is arranged close to the receiving surface 211, and along the vertical direction, the height of the limiting portion 215 is not less than the distance between the receiving surface 211 and the lower end surface of the abutting portion 311, and further, the height of the limiting portion 215 is substantially equal to the distance between the receiving surface 211 and the abutting portion The limit portion 215 can limit the horizontal displacement of the plate-like member between the receiving surface 211 and the abutting portion 311, that is, when the supporting member 21 supports the plate-like member, the receiving surface 211 and the lower end surface of the plate-like member are in contact, and at this time, there is a small gap between the limit portion 215 and the plate-like member. Since the supporting members 21 and 21' are provided on both sides of the silo 1, the limit portions 215 on both sides of the supported plate-like member have a guiding and limiting effect on the plate-like member. When the two When the two supporting members 21, 21' or the two clamping members 31, 33 are slightly out of sync, or when the plate-like member is partially stuck, the plate-like member is prone to tilt when falling, instead of falling vertically as expected. By providing a limiting portion 215 between the receiving surface 211 and the abutting portion 311, there is a small gap between the limiting portion 215 and the plate-like member, and the limiting portion 215 can limit the horizontal displacement of the plate-like member between the receiving surface 211 and the abutting portion 311, so that the limiting portion 215 can effectively prevent The plate-like member stopped between the first clamping member 31 or the second clamping member 33 and the main body 212 is skewed, which can effectively avoid the problem that one end of the plate-like member is between the clamping members 31, 33 and the supporting member 21, and the other end is not between the clamping members 31, 33 and the supporting member 21. Therefore, a limiting portion 215 is provided on the side of the main body 212 close to the clamping members 31, 33, which can guide the unclamped plate-like member and effectively prevent the situation where part of the plate-like member is supported and part is not supported due to the skew of the plate-like member.
[0028] like Figure 6 and Figure 7 Furthermore, the main body 212 includes a plurality of avoidance portions 2121, which divide the receiving surface 211 into a plurality of parts. The avoidance portions 2121 are provided to help reduce the contact area between the receiving surface 211 and the plate-like member, thereby effectively reducing the difficulty of processing the receiving surface 211. This is because a larger contact area requires a higher degree of flatness of the contact surface. For surface contact, the smaller the contact area, the lower the difficulty of processing.
[0029] like Figure 6 , Figure 7 and Figure 8The separation mechanism 4 includes a third power mechanism 42, and the third power mechanism 42 can drive the pushing piece 41 to reciprocate along a predetermined trajectory. The pushing piece 41 includes a pressing portion 411. In the vertical direction, the pressing portion 411 is arranged close to the first clamping piece 31 or the second clamping piece 33. The pressing portion 411 includes a contact surface 4111. When the third power mechanism 42 drives the pushing piece 41 to move away from the first clamping piece 31 or the second clamping piece 33, the contact surface 4111 of the pressing portion 411 contacts the flange portion of the unclamped plate-like piece, and as the pressing portion 411 continues to move downward, the unclamped plate-like piece is peeled off.
[0030] like Figure 7 Furthermore, the pushing member 41 is generally U-shaped, and the pressing portion 411 includes a first pressing portion 411a and a second pressing portion 411b, which extend along the movement direction of the pushing member 41, and one end of the first pressing portion 411a and the second pressing portion 411b close to the feed end 11 is fixedly connected to the third power mechanism 42, and in the horizontal direction, the first pressing portion 411a and the second pressing portion 411b are respectively located on both sides of the first clamping member 31 or the second clamping member 33, and the fixed connection here can be bolt connection, snap connection, welding, etc. The free ends of the first pressing portion 411a and the second pressing portion 411b include abutting surfaces 4111, and the abutting surfaces 4111 are arranged toward the plate-like member. Specifically, the abutting surfaces 4111 can abut against the flanged portion of the plate-like member. The first pressing portion 411a and the second pressing portion 411b push the end surfaces of the flanged portion through the abutting surfaces 4111, so that the plate-like member not clamped by the clamping mechanism 3 is detached from under the clamped plate-like member.
[0031] like Figure 7 The first clamping member 31 is located between the first pressing portion 411a and the second pressing portion 411b, and the lowest point of the downward movement of the first pressing portion 411a and the second pressing portion 411b is lower than the clamping surface 3111 of the first clamping member 31. In this way, the plate-like member located below the plate-like member clamped by the first clamping member 31 and the second clamping member 33 can be pushed down, thereby solving the problem of material cutting difficulty caused by the tight connection between the plate-like members and the difficulty in separation.
[0032] like Figure 5 The material unloading method of the unloading mechanism 100 at least comprises the following steps:
[0033] Step A: a certain amount of plate-like members are placed into the silo 1, and the supporting member 21 is in a state of supporting the plate-like members;
[0034] Step B: The first power mechanism 32 pushes the first clamping member 31 and the second clamping member 33 to move toward one side of the silo 1, and the first clamping member 31 and the second clamping member 33 clamp part of the plate-like member;
[0035] Step C: the third power mechanism 42 drives the pushing member 41 to move obliquely downward to push the plate-like member below the first clamping member 31 and / or the second clamping member 33;
[0036] Step D: The second power mechanism 22 drives the supporting member 21 to leave the discharge port 121;
[0037] Step E: The third power mechanism 42 drives the pushing member 41 to move obliquely upward;
[0038] Step F: The second power mechanism 22 drives the supporting member 21 to approach the discharge port 121, and at least partially closes the discharge port 121;
[0039] Step G: The first power mechanism 32 drives the first clamping member 31 and the second clamping member 33 to move away from the silo 1 .
[0040] When the unloading mechanism 100 performs step C, that is, when the unloading mechanism 100 is in the material discharging state, the pushing member 41, driven by the third power mechanism 42, pushes the plate-like members that are not clamped by the first clamping member 31 and / or the second clamping member 33 to separate them from the clamped plate-like members; when the unloading mechanism 100 performs step D, the supporting member 21 is away from the discharge port 121, and there is no shielding member at the discharge port 121, and the peeled plate-like members are output and fall from the discharge port 121; when the unloading mechanism 100 performs step G, the first power mechanism 32 drives the first clamping member 31 and the second clamping member 33 to move to the side away from the silo 1, the clamping force disappears, and the stacked plate-like members fall due to gravity and are supported by the supporting member 21.
[0041] In some embodiments, the unloading mechanism 100 operates in the order from step A to step G, but in some embodiments, some steps can be performed simultaneously, and in other embodiments, some steps can be adjusted in order, and a predetermined number of plate-like parts can be dropped without unloading. Specifically, the order of step C and step D in the above steps can be swapped, and the second power mechanism 22 first drives the supporting member 21 to leave the discharge port 121, and then the third power mechanism 42 drives the pushing member 41 to move obliquely downward, pushing the plate-like part under the clamping member to make it fall off and be output from the discharge port 121. Of course, step C and step D can also be performed simultaneously, and the effect of outputting the plate-like part under the clamping member can also be achieved. For another example, step E and step F in the above steps can also be performed simultaneously.
[0042] It should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail in this specification with reference to the above embodiments, it should be understood by those skilled in the art that the present invention can still be modified or replaced by equivalents, and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
