Description

Technical Field

[0001] The embodiments of the present invention relate to the field of machinery, and in particular to a fin transmission structure. Background Art

[0002] At present, for the transmission of fins, the fins are usually released from a high position and inserted into a predetermined transmission position of the transmission structure. In order to improve the transmission efficiency of the fins, the release speed of the fins is usually accelerated, and the fastest release speed of the fins can reach 0.75 seconds per fin.

[0003] The inventors have discovered that there are at least the following problems in the above-mentioned related technologies: since the fins will come into contact with the conveying structure when they are released from a high place and inserted into the predetermined conveying position of the conveying structure, the fins will rebound to a certain extent. This rebound phenomenon will cause the fin conveyance to be unsmooth and cause blockage, thus affecting the normal conveyance of the fins. Summary of the invention

[0004] The purpose of the embodiment of the present invention is to provide a fin conveying structure, which can reduce the rebound of the fin to a certain extent and enhance the fin conveying stability.

[0005] To solve the above technical problems, an embodiment of the present invention provides a fin conveying structure for receiving falling fins and conveying the fins, the conveying structure comprising: a first conveying member and a second conveying member arranged opposite to each other, a conveying space between the first conveying member and the second conveying member, the first conveying member being used to receive one end of the falling fin, a guide groove being provided on the first conveying member, the guide groove being used to accommodate one end of the falling fin and to guide the fin into the conveying space so as to convey the fin in the conveying space.

[0006] Compared with the related art, the embodiment of the present invention comprises a first conveying member and a second conveying member arranged opposite to each other, and a conveying space between the first conveying member and the second conveying member, and a guide groove is provided on the first conveying member. In the process of the fin falling from a high place to the conveying space of the conveying structure, one end of the fin first contacts with the guide groove of the first conveying member, and the guide groove accommodates one end of the falling fin, which effectively slows down the falling speed of the fin and avoids the rebound of the fin to a certain extent. After the guide groove receives one end of the fin, the fin is guided into the conveying space connected with the guide groove along the direction of the guide groove, so that the subsequent fin is conveyed in the conveying space. By carrying the falling fin by the guide groove and guiding the fin into the conveying space, the rebound of the fin can be slowed down to a certain extent, thereby improving the stability of the fin transmission.

[0007] In addition, the first transmission member is a first worm, and the second transmission member is a second worm. The first worm includes: a first worm, a first spiral tooth spirally arranged on the outer periphery of the first worm, and a spiral first tooth gap formed by the first spiral tooth. The second worm includes: a second worm, a second spiral tooth spirally arranged on the outer periphery of the second worm, and a spiral second tooth gap formed by the second spiral tooth. The guide groove is opened on the first spiral tooth, and the guide groove extends along the spiral setting direction of the first spiral tooth. The fin transmission structure also includes: a plurality of flat tubes located in the transmission space, one end of each flat tube is clamped in the first tooth gap, and the other end of the flat tube is clamped in the second tooth gap. The flat tubes are perpendicular to the first worm, and the guide groove is used to guide the fin between two adjacent flat tubes in the transmission space. The first worm and the second worm can both rotate, and the flat tube pushes the fin to be transmitted in the transmission space under the rotation drive of the first worm and the second worm.

[0008] In addition, the guide groove includes: an arc groove and a buffer groove sequentially arranged along the spiral setting direction of the first spiral tooth, the arc groove is used to receive one end of the fin and guide the one end of the fin to the buffer groove, and the buffer groove is used to guide the fin between two adjacent flat tubes in the conveying space, wherein the opening width of the arc groove gradually increases along the spiral setting direction. In this way, the fin can be inserted between the two flat tubes more stably.

[0009] In addition, the bottom surface of the arc-shaped groove is an arc surface arranged around the first worm, and the bottom surface of the buffer groove is a plane.

[0010] In addition, the flat tube pushes the fin to be transported on the conveying plane in the conveying space under the rotation drive of the first worm and the second worm, and the acute angle between the bottom surface of the buffer groove and the conveying plane of the fin is less than or equal to 60 degrees, wherein the conveying plane is perpendicular to the falling direction of the fin.

[0011] In addition, the length of the bottom surface of the buffer groove in the spiral arrangement direction of the first spiral tooth is half the length of the bottom surface of the arc groove in the spiral arrangement direction of the first spiral tooth.

[0012] In addition, the first spiral tooth includes a first tooth portion and a second tooth portion connected to the first tooth portion and provided with a groove, and the length of the second tooth portion in the axial direction of the worm is greater than the length of the first tooth portion in the axial direction of the worm. The spacing between the two flat tubes for accommodating the falling fins is increased, so that the fins are easily inserted between the two flat tubes.

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those skilled in the art that in the embodiments of the present invention, many technical details are provided to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can be implemented.

[0023] The following embodiments are divided for the convenience of description and shall not constitute any limitation on the specific implementation of the present invention. The embodiments may be combined with each other and referenced to each other without contradiction.

[0024] A feasible embodiment of the present invention relates to a fin conveying structure for receiving and conveying falling fins, such as Figure 1As shown, the conveying structure includes: a first conveying member 1 and a second conveying member 2 arranged opposite to each other, a conveying space 3 located between the first conveying member 1 and the second conveying member 2, the first conveying member 1 is used to receive one end of the falling fin, and a guide groove 11 is opened on the first conveying member 1, the guide groove 11 is used to accommodate one end of the falling fin and guide the fin into the conveying space 3 to convey the fin in the conveying space 3.

[0025] Compared with the related art, the embodiment of the present invention comprises a first conveying member and a second conveying member arranged opposite to each other, and a conveying space between the first conveying member and the second conveying member, and a guide groove is provided on the first conveying member. In the process of the fin falling from a high place to the conveying space of the conveying structure, one end of the fin first contacts with the guide groove of the first conveying member, and the guide groove accommodates one end of the falling fin, which effectively slows down the falling speed of the fin and avoids the rebound of the fin to a certain extent. After the guide groove receives one end of the fin, the fin is guided into the conveying space connected with the guide groove along the direction of the guide groove, so that the subsequent fin is conveyed in the conveying space. By carrying the falling fin by the guide groove and guiding the fin into the conveying space, the rebound of the fin can be slowed down to a certain extent, thereby improving the stability of the fin transmission.

[0026] In addition, the first conveying member and the second conveying member arranged opposite to each other in the conveying device may be a worm structure, or may be a roller structure or other structures used for conveying. The following takes the first conveying member as the first worm and the second conveying member as the second worm as an example to specifically describe the fin conveying structure:

[0027] like Figures 2 to 3 As shown, the first transmission member is a first worm 1, and the second transmission member is a second worm 2. The first worm 1 includes: a first worm 12, a first spiral tooth 13 spirally arranged on the outer periphery of the first worm 12, and a spiral first inter-tooth gap 14 formed by the first spiral tooth. The second worm 2 includes: a second worm, a second spiral tooth spirally arranged on the outer periphery of the second worm, and a spiral second inter-tooth gap formed by the second spiral tooth. The guide groove 11 is opened on the first spiral tooth, and the guide groove 11 extends along the spiral setting direction of the first spiral tooth 13. The fin transmission structure also includes: a plurality of flat tubes 4 located in the transmission space, one end of each flat tube 4 is clamped in the first inter-tooth gap, and the other end of the flat tube is clamped in the second inter-tooth gap. The flat tubes 4 are perpendicular to the first worm 12. The guide groove 11 is used to guide the fin into the transmission space between two adjacent flat tubes (shown in the figure at position 31). The first worm 1 and the second worm 2 can both rotate, and the flat tubes push the fins to be transmitted in the transmission space under the rotation drive of the first worm 1 and the second worm 2.

[0028] In actual application, multiple first inter-tooth gaps and multiple second inter-tooth gaps in the figure are all sandwiched with flat tubes, and the fins continue to fall at a certain frequency. After the first fin is introduced between the two flat tubes (position 31 in the figure), the first worm 1 and the second worm 2 rotate by a certain angle, and the flat tube moves in the preset conveying direction as the first worm and the second worm rotate, driving the fins between the two flat tubes to also move in the preset conveying direction, which results in the position where the fin falls being vacated for the next fin to fall and be introduced between the two flat tubes. The above process is repeated to realize the conveying of the fins in the conveying space.

[0029] In addition, the guide groove can be a groove with an arc-shaped bottom surface or a groove with a flat bottom surface, or the guide groove can be formed by combining a groove with an arc-shaped bottom surface and a groove with a flat bottom surface.

[0030] The following specifically describes how to form a guide groove by combining a groove with an arc bottom surface and a groove with a flat bottom surface. Figures 2 to 4 As shown, the guide groove 11 includes: an arc groove 111 and a buffer groove 112 sequentially arranged along the spiral setting direction of the first spiral tooth, the arc groove 111 is used to receive one end of the fin and guide the one end of the fin to the buffer groove 112, and the buffer groove 112 is used to guide the fin between two adjacent flat tubes in the conveying space, wherein the opening width of the arc groove 111 gradually increases along the spiral setting direction, so that the fin can move along the direction of increasing opening width, and the fin is conveniently introduced into the buffer groove 112. In practical applications, the opening width of the arc groove can be set based on the width of the fin to match fins of different models.

[0031] In addition, the bottom surface of the arc-shaped groove is an arc surface arranged around the first worm, and the bottom surface of the buffer groove is a plane. The bottom surface of the arc-shaped groove is set as an arc surface, so that the depth of the arc-shaped groove portion can reach a certain value, thereby preventing the fin from detaching from the arc-shaped groove when falling into the arc-shaped groove, thereby ensuring that the fin can be introduced into the buffer groove through the arc-shaped groove. The depth of the groove can usually be set according to the fin. For example, the depth of the groove can be set to half the length of the fin in the insertion direction, thereby ensuring that the fin will not pop out of the groove after entering the groove. The bottom surface of the buffer groove is set as a plane, which allows the fin to slide in between the two flat tubes more smoothly, thereby avoiding vibration of the fin in the process of entering between the two flat tubes.

[0032] In addition, the flat tubes push the fins to be transported on the transport plane in the transport space under the rotational drive of the first worm and the second worm, and the acute angle between the bottom surface of the buffer groove and the transport plane of the fins is less than or equal to 60 degrees, wherein the transport plane is perpendicular to the falling direction of the fins. Controlling the angle between the bottom surface of the buffer groove and the transport plane can make the fins enter between the two flat tubes at a smaller inclination angle, avoid rebound or vibration of the fins, and improve the stability of fin transmission.

[0033] In addition, the length of the bottom surface of the buffer groove in the spiral setting direction of the first spiral tooth is half the length of the bottom surface of the arc groove in the spiral setting direction of the first spiral tooth, ensuring the sliding length of one end of the fin in the buffer groove and further improving the stability of the fin.

[0034] In addition, if Figure 5 As shown, the first spiral tooth includes a first tooth portion 131 and a second tooth portion 132 connected to the first tooth portion 131 and provided with a groove, and the length of the second tooth portion 132 in the axial direction of the worm is greater than the length of the first tooth portion 131 in the axial direction of the worm. The spacing between the two flat tubes for accommodating the falling fins is increased, so that the fins are easily inserted between the two flat tubes. The difference between the length of the second tooth portion in the axial direction of the worm and the length of the first tooth portion in the axial direction of the worm can be within the range of 1.5 mm to 2.5 mm.

[0035] In addition, if Figure 5 As shown, the first spiral tooth may further include a third tooth portion 133, and the spiral inter-tooth gap formed by the third tooth portion 133 gradually decreases in the spiral setting direction, so that the flat tube can be gradually fixed in a vertical state during the process of transmitting the flat tube using the inter-tooth gap.

[0036] In addition, the fin conveying structure further includes: a release device, which is arranged above the groove and is used to release the fin so that the fin falls. The fin conveying structure may also include: a blowing device arranged adjacent to the release device, the release device includes: a release channel, the end of the release channel is arranged just above the groove, and the blowing device is used to blow the fin into the release channel using airflow. This can provide assistance for the fin to enter the release channel and assist the fin to move in the release channel.

[0037] Compared with the related art, the above-mentioned embodiment of the present invention has a relatively stable transmission effect for fins that require high-speed transmission, reduces the generation of unstable factors such as blockage, improves the transmission efficiency of the fins, and meets the production requirements of the product.

[0038] Those skilled in the art will appreciate that the above embodiments are specific embodiments for implementing the present invention, and that in actual applications, various changes may be made in form and detail without departing from the spirit and scope of the present invention.
