Description

Technical Field

[0001] The invention relates to the technical field of heat exchanger flat tube production equipment, and in particular to a flat tube discharge device. Background Art

[0002] Flat tube heat exchanger is an energy-saving device that realizes heat transfer between two or more fluids at different temperatures. It is one of the main equipment that transfers heat from a higher temperature fluid to a lower temperature fluid, so that the fluid temperature reaches the specified index of the process to meet the needs of process conditions and improve energy utilization. It can be mainly used in the fields of petroleum, chemical industry, metallurgy, electric power, shipbuilding, central heating, refrigeration and air conditioning, machinery, food and pharmaceuticals.

[0003] When assembling the flat tube heat exchanger, the flat tubes are generally arranged in a silo and discharged one by one to the conveying worm through a discharge device for subsequent assembly. Among them, the discharge speed and quality of the flat tubes have a great influence on the assembly efficiency and accuracy of the entire flat tube heat exchanger.

[0004] At present, the method used is to push out the flat tubes at the bottom of the bin by moving the material-beating assembly back and forth horizontally or rolling the flat tubes out through a circular roller, and then drop them into the conveying worm through the track. Since the material-beating assembly or the circular roller reciprocates on the flat tubes, it is easy to cause friction damage to the flat tubes, which slows down the discharge speed of the flat tubes and reduces the work efficiency. In addition, the manufacturing cost of the circular roller is high.

[0033] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0034] Any feature disclosed in this specification, unless otherwise stated, may be replaced by other equivalent or alternative features having similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features. Throughout the specification, the same reference numerals indicate the same elements.

[0035] In order to make the technical problem solved by the present invention, the technical solution adopted and the technical effect achieved more clearly, the technical solution of the present invention is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0036] This embodiment proposes a flat tube discharge device, which can discharge the flat tubes 3 from the silo one by one, and then transfer the flat tubes 3 to the transfer worm through the motion track, so as to facilitate the subsequent assembly of the flat tube 3 heat exchanger. Figure 1 As shown, the flat tube discharging device comprises a driving member, a material beating assembly 4 and an intermediate connecting rod mechanism 1. The material beating assembly 4 abuts against the flat tube 3 to discharge the flat tube 3; one end of the intermediate connecting rod mechanism 1 is connected to the driving member, and the other end is connected to the material beating assembly 4. The driving member drives the intermediate connecting rod mechanism 1 to move, so as to drive the material beating assembly 4 to return to the original point after discharging the flat tube 3, and not to contact the next flat tube 3.

[0037] The intermediate connecting rod mechanism 1 is connected to the driving member and the material beating assembly 4 respectively; when the driving member drives the intermediate connecting rod mechanism 1 to move, the intermediate connecting rod mechanism 1 can drive the material beating assembly 4 to move. Due to the specific movement trajectory of the intermediate connecting rod mechanism 1, the material beating assembly 4 can smoothly discharge the flat tube 3, and when the material beating assembly 4 returns to the original point from the discharge point, the material beating assembly 4 has a downward curved movement trajectory, which can avoid contact with the next flat tube 3; no friction will be generated between the material beating assembly 4 and the flat tube 3, and friction damage to the flat tube 3 that has not been discharged can be avoided, so that the discharge speed of the flat tube 3 is faster, time is saved, and work efficiency is higher.

[0038] At the same time, it can also avoid the friction damage of the material-beating component 4, and it is no longer necessary to prepare a spare material-beating component 4, nor is it necessary to manually replace the damaged material-beating component 4, which greatly reduces the labor and maintenance costs and makes the production cost lower. And the flat tube 3 will not be damaged due to the wear of the material-beating component 4, so that the entire flat tube 3 heat exchanger needs to be rearranged, wasting materials and time.

[0039] Specifically, the flat tube discharge device also includes a connecting component 2, one end of the connecting component 2 is connected to the intermediate connecting rod mechanism 1, and the other end is connected to the material beating component 4. The connecting component 2 is configured to transmit the movement of the intermediate connecting rod mechanism 1 to the material beating component 4, so that the material beating component 4 moves according to the movement trajectory of the intermediate connecting rod mechanism 1, so as to avoid friction between the material beating component 4 and the next flat tube 3 to be discharged when returning from the discharge point to the origin, thereby preventing the flat tube 3 from being damaged.

[0040] Further, the connection assembly 2 includes a first connection block 21 and a connection shaft 23. The first connection block 21 is connected to the intermediate linkage mechanism 1. The connection shaft 23 vertically passes through the first connection block 21, and the end of the connection shaft 23 abuts against the material beating assembly 4. The first connection block 21 drives the connection shaft 23 to move, so as to move the material beating assembly 4. The connection assembly 2 also includes a second connection block 22, which is vertically located on the upper side of the first connection block 21. The connection shaft 23 vertically passes through the second connection block 22. The connection shaft 23 can move vertically relative to the second connection block 22 to drive the material beating assembly 4 to move in the vertical direction.

[0041] In this embodiment, since the flat tube 3 needs to be discharged smoothly, that is, the load on the connecting shaft 23 and the first connecting block 21 and the second connecting block 22 is small, oil-free bushings are provided at the contact positions. Providing oil-free bushings can also reduce the wear of the connecting shaft 23 and the first connecting block 21 and the second connecting block 22.

[0042] When the intermediate connecting rod mechanism 1 drives the connecting shaft 23 to move vertically, the connecting shaft 23 can move vertically relative to the second connecting block 22, that is, the connecting shaft 23 only drives the punching assembly 4 to move in the vertical direction, and the second connecting block 22 and the slider 6 remain stationary.

[0043] like Figure 2 As shown, the flat tube discharge device also includes a guide rail 5 and a slider 6. The slider 6 is connected to the second connecting block 22. The connecting shaft 23 drives the material beating component 4 to move in the horizontal direction, so that the material beating component 4, the second connecting block 22 and the slider 6 slide along the guide rail 5, so that the material beating component 4 moves in the horizontal direction.

[0044] When the intermediate link mechanism 1 drives the connecting shaft 23 to move horizontally, the connecting shaft 23 drives the material-beating assembly 4 to move horizontally along the guide rail 5 to smoothly discharge the flat tubes 3. The slider 6 and the guide rail 5 enable the material-beating assembly 4 to move more stably in the horizontal direction, so that the flat tubes 3 can be discharged smoothly one by one.

[0045] The connecting shaft 23 is driven to move by the intermediate connecting rod mechanism 1, so that the motion trajectory of the intermediate connecting rod mechanism 1 is transmitted to the connecting shaft 23, so that the connecting shaft 23 drives the material-beating assembly 4 to move in the horizontal direction first, discharges the flat tube 3, and then when the material-beating assembly 4 returns to the origin from the discharge point, the connecting shaft 23 can drive the material-beating assembly 4 to have a motion trajectory in both the horizontal and vertical directions, that is, the material-beating assembly 4 has a downward curved motion trajectory, so as to avoid contact and friction with the next flat tube 3, and prevent the flat tube 3 and the material-beating assembly 4 from being damaged. Among them, the motion trajectory of the material-beating assembly 4 is as follows: Figure 2 As shown by arrow A.

[0046] In this embodiment, the beating assembly 4 includes a first beating block 41 and a second beating block 42. The first beating block 41 is vertically located on the upper side of the second beating block 42, and the bottom end of the second beating block 42 abuts against the connecting shaft 23, so that the connecting shaft 23 moves with the second beating block 42, and the bottom end of the second beating block 42 is a horizontal plane, so as to abut against the end of the connecting shaft 23. The top end of the first beating block 41 is provided with a protrusion running through its length direction, and the protrusion contacts the flat tube 3 to beat the flat tube 3 to discharge.

[0047] Furthermore, the intermediate connecting rod mechanism 1 includes a stationary rod, a connecting rod 11, a driven rod 12, an intermediate rod 13 and an intermediate rod extension section 14. One end of the connecting rod 11 is fixedly connected to the output shaft 7 of the driving member, and the other end is hinged to the upper end of the intermediate rod 13. The lower end of the intermediate rod 13 is hinged to one end of the driven rod 12, and the lower end of the intermediate rod 13 is integrally formed and extends downward to form the intermediate rod extension section 14. Among them, the connecting rod 11 is eccentrically connected to the output shaft 7, and the output shaft 7 drives the connecting rod 11 to rotate; wherein, the distance between the axis of the output shaft 7 and the axis of the connecting rod 11 is the driving rod.

[0048] Specifically, a connecting hole 111 is provided at one end of the connecting rod 11, and a fastener 71 matching the connecting hole 111 is provided on the output shaft 7. By inserting the fastener 71 into the connecting hole 111, one end of the connecting rod 11 is fixed to the output shaft 7, so that the output shaft 7 drives the connecting rod 11 to move. In this embodiment, the driving member is a motor.

[0049] Further, one end of the intermediate rod extension section 14 is fixedly connected to the first connection block 21, and the intermediate rod extension section 14 drives the first connection block 21, the connection shaft 23 and the second connection block 22 to move. The flat tube discharge device also includes a connecting member (not shown in the figure) and a support member 8, which is arranged at the bottom end of the flat tube 3 and is configured to support the flat tube 3. One end of the connecting member is fixedly connected to the support member 8, and the other end of the connecting member is fixedly connected to the other end of the driven member 12. The stationary rod is the distance from the axis of the output shaft 7 to the other end of the driven rod 12.

[0050] When the connecting rod 11 drives the intermediate rod 13 to move, since one end of the driven rod 12 is hinged to the other end of the intermediate rod 13, and the other end of the driven rod 12 is fixed on the connecting piece, the intermediate rod 13 drives one end of the driven rod 12 to move, thereby limiting the rotation of the intermediate rod 13; at the same time, since the other end of the intermediate rod 13 is integrally formed and extended to form an intermediate rod extension section 14, the intermediate rod 13 and the intermediate rod extension section 14 have the same movement, and one end of the intermediate rod extension section 14 is fixedly connected to the first connecting block 21.

[0051] The middle rod extension section 14 drives the first connection block 21 to move, so that the connection shaft 23 drives the material-beating assembly 4 to move, and the motion trajectory of the middle rod extension section 14 is transmitted to the material-beating assembly 4 through the connection shaft 23, and the motion trajectory of the middle rod extension section 14 is the motion trajectory of the material-beating assembly 4. That is, the middle connecting rod mechanism 1 in this embodiment can ensure that the motion trajectory of the material-beating assembly 4 is relatively close to horizontal linear motion and downward curved motion, so that the material-beating assembly 4 can discharge the flat tube 3, and at the same time, the material-beating assembly 4 can not contact the next flat tube 3 when returning to the origin from the discharge point.

[0052] In this embodiment, the motion trajectory of the intermediate rod extension section 14 is the motion trajectory of the material beating assembly 4. That is, the intermediate connecting rod mechanism 1 in this embodiment can ensure that the motion trajectory of the material beating assembly 4 is: the first half is a relatively horizontal straight line motion, and the second half is a downward curved motion, so that the material beating assembly 4 can discharge the flat tube 3, and at the same time, the material beating assembly 4 can return to the origin from the discharge point without contacting the next flat tube 3. In other embodiments, the intermediate connecting rod mechanism 1 can also make the motion trajectory of the material beating assembly 4 be: the first half is a curved motion, and the second half is a relatively horizontal straight line motion. Among them, the direction of the curved motion needs to be determined according to actual work needs.

[0053] The different motion trajectories of the material beating component 4 need to be set by setting different lengths of the stationary rods so that the material beating component 4 can obtain different motion trajectories. The specific motion trajectory of the material beating component 4 needs to be determined according to the actual production requirements and the length of the stationary rod.

[0054] Furthermore, when the length ratio of the stationary rod, the driving rod, the driven rod 12, the intermediate rod 13 and the intermediate rod extension section 14 is 2:1:2.5:2.5:2.5, the punching assembly 4 can discharge the flat tube 3 smoothly, and the effect of not contacting the next flat tube 3 when returning from the discharge point to the origin is better. In this embodiment, when the length value of the driving rod is 10 mm, the discharge requirement of the flat tube 3 can be better met.

[0055] The specific movement process of the flat tube discharge device in this embodiment is as follows: first, the driving member rotates to rotate the output shaft 7 of the driving member; the output shaft 7 drives the connecting rod 11 to rotate, and the connecting rod 11 drives the intermediate rod 13 and the driven rod 12 to rotate, and then the intermediate rod extension section 14 drives the first connecting block 21 to move, so that the connecting shaft 23 on the first connecting block 21 moves, and the connecting shaft 23 drives the material beating assembly 4, the second connecting block 22 and the slider 6 to move horizontally along the guide rail 5, so that the material beating assembly 4 discharges the flat tube 3; finally, on the basis of horizontal movement, the connecting shaft 23 can simultaneously drive the material beating assembly 4 to move in the vertical direction, so that the movement trajectory of the material beating assembly 4 is a downward curved movement, so as to avoid the flat tube 3, return to the origin, and perform the discharge work of the next flat tube 3.

[0056] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
