Description

Technical Field

[0001] This invention relates to the field of continuous casting technology for copper rods, and more particularly to a conveying and support structure for the fan-shaped section of a copper rod billet. Background Technology

[0002] In the continuous casting process of copper rods, the fan-shaped section is a key link in realizing the transformation of product shape and adjustment of conveying direction. Its core function is to smoothly transition and straighten the vertical casting billet, which has just been pulled out of the crystallizer and is still in a high-temperature plastic state, into a horizontal copper rod through a series of precisely arranged support and guide elements, so that it can enter the subsequent rolling or cooling process. This arc-shaped movement trajectory from vertical to horizontal places extremely high demands on the support performance of the conveying structure.

[0003] Traditional sector sections typically use multiple arc-shaped conveyor rollers as support and transmission components. However, in this structure, the high-temperature and low-mechanical-strength copper rod billet only makes narrow contact with a limited number of roller surfaces, resulting in a small actual bearing area. Under the weight of the billet and the traction tension, the limited contact area will bear a large concentrated load, causing a significant increase in local pressure at the contact point. This excessive pressure can easily cause plastic defects such as indentations, scratches, and even cross-sectional deformation on the surface of the copper rod before it has fully solidified. This directly affects the geometric accuracy, surface quality, and internal structure uniformity of the product, thus restricting the quality and yield of the final copper rod. Summary of the Invention

[0004] This invention provides a fan-shaped section conveying support structure for copper rod castings, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A fan-shaped section conveying support structure for copper rod casting billets includes a first conveying structure and a second conveying structure arranged opposite to each other, wherein the first conveying structure and the second conveying structure form a conveying channel for the casting billet.

[0007] The conveying structure includes two rotary tracks distributed front to back and a plurality of extrusion bodies located between the two rotary tracks and moving along the trajectory of the rotary tracks. The rotary track is composed of an arc section and a rotary section.

[0008] The second conveying structure includes two rotary tracks distributed in front and behind, and a plurality of extrusion bodies located between the two rotary tracks and moving along the trajectory of the rotary tracks. The rotary track is composed of an arc segment and a rotary segment. The arc segment corresponds to the arc segment and is concentrically arranged.

[0009] An extrusion groove 1 and an extrusion groove 2 are respectively provided in the middle of the extrusion body 1 and the middle of the extrusion body 2. The extrusion groove 1 and the extrusion groove 2 form a circle, and in the trajectory direction of the arc segment 1, the extrusion groove 1 and the extrusion groove 2 are both arcs concentric with the arc segment.

[0010] Furthermore, several extrusion bodies one and several extrusion bodies two respectively abut against each other on the corresponding arc segment one and arc segment two.

[0011] Furthermore, the conveying structure one also includes a fixing plate, a pressing unit mounted on the fixing plate for conveying the extruded body one into the arc-shaped section one, a releasing unit for conveying the extruded body one in the arc-shaped section one into the rotary section one, and a pushing unit one for providing moving power to the extruded body one in the arc-shaped section one.

[0012] The two adjacent extrusion bodies are connected by auxiliary units.

[0013] Furthermore, the pressing unit includes a side push plate slidably disposed on the fixed plate and an elastic body for providing elastic thrust to the side push plate. The side push plate is provided with a reverse thrust surface and a side push surface, and the pressing body is provided with a rotating wheel that is compatible with the reverse thrust surface or the side push surface.

[0014] Furthermore, the release unit includes a support body fixed relative to the rotary track, the side wall of the support body facing the arc segment is set as an arc surface, and the arc surface is concentric with the arc segment. A transmission belt is driven on the support body, and a plurality of buckles are provided on the transmission belt. At least one of the plurality of buckles is used in conjunction with the corresponding extrusion body.

[0015] Furthermore, the pushing unit 1 includes a rotating column that rotates on the rotary track 1. The outer wall of the rotating column is provided with a spiral groove. Each of the extrusion bodies 1 is provided with a deflector 1 that cooperates with the spiral groove on its side wall, and there is at least one deflector 1 on the spiral groove.

[0016] Furthermore, along the axis of the rotating column, the pitch of the helical groove gradually decreases;

[0017] The first pusher is slidably mounted on the first extrusion body via a slide block, and the slide block and the first extrusion body are connected by an elastic body.

[0018] Furthermore, both the first and second rotary tracks are provided with guide grooves, and both the sidewall of the first extrusion body and the sidewall of the second extrusion body are provided with a number of movable wheels that cooperate with the guide grooves. The number of movable wheels are arranged in sequence, and adjacent movable wheels are connected to each other through transmission. Adjacent movable wheels are respectively in transmission contact with the two inner sidewalls of the guide groove.

[0019] Furthermore, the auxiliary unit includes two inclined arms that are rotatably connected to each other. The two inclined arms are respectively rotatably connected to two adjacent extrusion bodies or two adjacent extrusion bodies. One of the inclined arms is provided with a limiting body for limiting the opening angle of the two inclined arms.

[0020] Furthermore, the first extrusion body and the second extrusion body are respectively provided with protrusions and grooves that cooperate with each other;

[0021] The second conveying structure further includes a second pushing unit for conveying the second extruded body into the second arc-shaped segment.

[0022] The technical solution of this invention can achieve the following technical effects:

[0023] This effectively solves the problem of concentrated force during the traditional copper rod casting process. It allows the extrusion groove 1 on extrusion body 1 and the extrusion groove 2 on extrusion body 2 to perfectly fit together in both the circumferential direction and the arc-shaped conveying direction of the copper rod, improving the protection of the copper rod's shape and increasing the force-bearing area. At the same time, since both extrusion body 1 and extrusion body 2 can move synchronously with the copper rod, static conveying can be achieved, improving the stability of the copper rod conveying and preventing tearing damage to the copper rod surface due to friction or gravity. By utilizing the cyclic movement of extrusion body 1 and extrusion body 2 on rotary tracks 1 and 2 respectively, continuous conveying of the copper rod can be achieved.

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0041] like Figures 1 to 5 As shown, this application provides a copper rod billet fan-shaped section conveying support structure, including a conveying structure 100 and a conveying structure 200 arranged opposite to each other, and the conveying structure 100 and the conveying structure 200 form a conveying channel for the billet.

[0042] The conveying structure 100 includes two rotary tracks 101 distributed in front and behind, and a number of extrusion bodies 104 located between the two rotary tracks 101 and moving along the trajectory of the rotary tracks 101. The rotary track 101 is composed of an arc-shaped section 102 and a rotary section 103.

[0043] The conveying structure 200 includes two rotary tracks 201 distributed in front and behind, and several extrusion bodies 204 located between the two rotary tracks 201 and moving along the trajectory of the rotary tracks 201. The rotary track 201 is composed of an arc-shaped section 202 and a rotary section 203. The arc-shaped section 102 corresponds to the arc-shaped section 202 and is concentrically arranged.

[0044] Extrusion groove 105 and extrusion groove 205 are respectively provided in the middle of extrusion body 104 and extrusion body 204. Extrusion groove 105 and extrusion groove 205 form a circle, and in the trajectory direction of arc segment 102, extrusion groove 105 and extrusion groove 205 are both arcs concentric with arc segment 102.

[0045] Specifically, conveyor structure 100 is located diagonally above conveyor structure 200, or conveyor structure 200 is located diagonally above conveyor structure 100. The space between conveyor structure 100 and conveyor structure 200 is arc-shaped, and this arc-shaped space is used to convey the copper rod casting billet, changing the copper rod casting billet from a vertical conveying state to a horizontal conveying state. Since the billet conveying operation is only restricted by the conveying channel, the relative position of conveyor structure 100 and conveyor structure 200 is not restricted; it only needs to form a conveying channel. Rotary track 101 and rotary track 201 can be supported and fixed by an external frame, thereby fixing the overall structure. Figure 1 For example, conveyor structure 100 is located on the upper side of conveyor structure 200. Two rotary tracks 101, distributed front to back, correspond to two rotary tracks 201, also distributed front to back. The two rotary tracks 101 and 201 can guide several extruded bodies 104 and 204 respectively. The arc-shaped segments 102 on rotary track 101 and 202 on rotary track 201 are concentric and have equal curvature. This allows the extruded bodies 104 and 204 to move within the arc-shaped segments 102 and 202 respectively, while the rotary tracks 101 and 201 move in tandem. The rotating sections 101 and 201 are relatively stationary, allowing the copper rod to be statically clamped and stably transported. The rotating sections 103 and 203 can guide the rotating extrusion bodies 104 and 204, enabling them to move from the bottom of the corresponding arc-shaped sections 102 and 202, around them, and then to the top of the arc-shaped sections 102 and 202. This allows the extrusion bodies 104 and 204 to perform continuous rotating motion on the rotating sections 101 and 201.

[0046] The cross-sectional shape of extrusion groove 105 and extrusion groove 205 on the plane where the axis of arc segment 102 is located is circular, which can achieve full circumferential wrapping of the copper rod. At the same time, along the circumferential direction of the circle where arc segment 102 is located, extrusion groove 105 and extrusion groove 205 are both arc-shaped, and their curvature is consistent with the curvature of the copper rod. This allows the inner wall of extrusion groove 105 and the inner wall of extrusion groove 205 to fully contact the arc-shaped copper rod, making it convenient for extrusion groove 105 and extrusion groove 205 to be used with arc-shaped copper rods.

[0047] In use, several extrusion bodies 104 and 204 rotate on corresponding rotary tracks 101 and 201, respectively. When extrusion bodies 104 and 204 move to the top of arc-shaped sections 102 and 202, respectively, they approach each other, and extrusion grooves 105 and 205 combine to clamp the copper rod. At this time, the curvature of extrusion grooves 105 and 205 in the circumferential direction of the arc-shaped section 102 can compress the copper rod to cause a small deformation, which allows the copper rod to smoothly adapt to the subsequent arc-shaped conveying state. As the copper rod billet continues to be output, extrusion bodies 104 and 204 rotate on the arc-shaped sections 102 and 202, respectively. Section 202 moves downwards, and arc-shaped section 102 and arc-shaped section 202 simultaneously guide the copper rod. When extrusion body 104 and extrusion body 204 move to the bottom of arc-shaped section 102 and arc-shaped section 202, extrusion body 104 and extrusion body 204 separate from the copper rod. Then, using rotary section 103 and rotary section 203, extrusion body 104 and extrusion body 204 move back to the top of arc-shaped section 102 and arc-shaped section 202, thereby enabling extrusion body 104 and extrusion body 204 to move continuously and continuously clamp and transport the copper rod. When the copper rod moves in the transport channel, several extrusion body 104 and several extrusion body 204 will clamp the copper rod at the same time, thereby improving the stability of copper rod transport.

[0048] The technical solution of this invention effectively solves the problem of concentrated force during the traditional copper rod casting process. It facilitates the perfect fit between the extrusion groove 105 on extrusion body 104 and the extrusion groove 205 on extrusion body 204 in both the circumferential direction and the arc-shaped conveying direction of the copper rod, improving the protection of the copper rod's shape and increasing the force-bearing area. Furthermore, since both extrusion body 104 and extrusion body 204 can move synchronously with the copper rod, static conveying can be achieved, improving the stability of the copper rod conveying and preventing tearing damage to the copper rod surface due to friction or gravity. The continuous conveying of the copper rod can be achieved by utilizing the cyclic movement of extrusion body 104 and extrusion body 204 on rotary tracks 101 and 201, respectively.

[0049] Furthermore, several extrusion bodies 104 and several extrusion bodies 204 abut against each other on the corresponding arc-shaped segments 102 and 202, respectively.

[0050] like Figure 3As shown, arc segment 102 and arc segment 202 correspond to the conveying channel formed by conveying structure 100 and conveying structure 200. In this area, several extrusion bodies 104 on arc segment 102 are arranged sequentially along the trajectory of arc segment 102 and abut against each other. Several extrusion bodies 204 on arc segment 202 are arranged sequentially along the trajectory of arc segment 202 and abut against each other. Thus, several extrusion bodies 104 and several extrusion bodies 204 form a complete arc structure. This arc structure can fully contact the outer wall of the copper rod in the conveying channel. This can fully shape and clamp the copper rod of the fan-shaped segment, increase the contact area of ​​the copper rod, and since several extrusion bodies 104 and several extrusion bodies 204 can circulate, the synchronous conveying function of the copper rod can be realized in the conveying channel.

[0051] As can be seen from the above embodiments, the extrusion bodies 104 within the arc-shaped segment 102 abut against each other. Based on the shape characteristics of the extrusion bodies 104, when they move within the rotating segment 103, adjacent extrusion bodies 104 cannot abut against each other; sufficient distance is required between them to prevent jamming of adjacent extrusion bodies 104 within the rotating segment 103. That is, the extrusion bodies 104 within the arc-shaped segment 102 abut against each other, while the extrusion bodies 104 within the rotating segment 103 separate from each other. To achieve this, such as... Figure 1 As shown, the conveying structure 100 also includes a fixed plate 106, a pressing unit mounted on the fixed plate 106 for conveying the extruded body 104 into the arc-shaped section 102, a releasing unit 107 for conveying the extruded body 104 in the arc-shaped section 102 into the rotary section 103, and a pushing unit 108 for providing moving power to the extruded body 104 in the arc-shaped section 102.

[0052] The two adjacent extrusion bodies 104 and the two adjacent extrusion bodies 204 are connected by auxiliary units.

[0053] The pressure conveying unit is set at Figure 1The pressing unit and the releasing unit 107 are located on the upper and lower sides of the arc-shaped section 102, respectively. The pressing unit can actively feed the extruded body 104 in the rotary section 103 into the arc-shaped section 102. The releasing unit 107 can move the extruded body 104 in the arc-shaped section 102 out one by one into the rotary section 103, thereby ensuring that there are always enough extruded bodies 104 in the arc-shaped section 102 and that the extruded bodies 104 can abut against each other. The extruded body 104 in the arc-shaped section 102 can be pushed and moved by the pushing unit 108. In some embodiments, the pushing unit 108 may not be provided. In this case, the movement of the extrusion bodies 104 on the rotary track 101 is mainly powered by the pressing unit. Since the adjacent extrusion bodies 104 are connected by an auxiliary unit, the movement of the extrusion bodies 104 in the arc section 102 can pull the extrusion bodies 104 in the rotary section 103 to move, so that the extrusion bodies 104 can rotate continuously. There are no restrictions on the movement of the extrusion bodies 104 on the rotary section 103, as long as the movement of the extrusion bodies 104 is allowed.

[0054] It should be noted that when there are enough extrusion bodies 104 on the rotary track 101, on the premise that the extrusion bodies 104 on the arc section 102 can abut against each other, the rotary section 103 also has a large number of extrusion bodies 104. At this time, at least some of the extrusion bodies 104 on the rotary section 103 can be separated from each other, and the two adjacent extrusion bodies 104 in the remaining part of the extrusion bodies 104 are allowed to contact each other in part. This allows the extrusion bodies 104 on the rotary section 103 to have enough room to move, and also ensures that the connection between the extrusion bodies 104 is not in a tense state.

[0055] The extrusion bodies 204 on the conveying structure 200 also have the above-mentioned characteristics in the arc section 102 and the rotary section 103, which will not be elaborated here.

[0056] Furthermore, such as Figure 7 As shown, the pressing unit includes a side push plate 109 slidably disposed on a fixed plate 106 and an elastic body 110 for providing elastic thrust to the side push plate 109. A reverse thrust surface 111 and a side push surface 112 are provided on the side push plate 109, and a roller 113 that is compatible with the reverse thrust surface 111 or the side push surface 112 is provided on the extrusion body 104.

[0057] One end of the elastic body 110 is connected to the side push plate 109, and the other end is mounted on the fixed plate 106 or fixed relative to the rotary track 101. Thus, when the elastic body 110 undergoes elastic deformation, it provides elastic force to the side push plate 109. When the pushing unit 108 provides moving power to several extrusion bodies 104 on the arc-shaped section 102, since adjacent extrusion bodies 104 are connected by an auxiliary unit, the extrusion bodies 104 in the rotary section 103 can be pulled into the arc-shaped section 102. Because there is a gap between adjacent extrusion bodies 104 in the rotary section 103, the pressing unit can shorten this gap and make the adjacent extrusion bodies 104 abut against each other. Specifically, the extrusion bodies in the arc-shaped section 102... The auxiliary unit pulls the extrusion body 104 in the rotating section 103 to move. The extrusion body 104 can contact the reverse thrust surface 111. At this time, the extrusion body 104 pushes the side push plate 109 to slide and extrude the elastic body 110 through the reverse thrust surface 111. When the extrusion body 104 moves to the side push surface 112, the elastic force provided by the elastic body 110 to the side push plate 109 will provide a lateral thrust to the extrusion body 104 through the side push surface 112, so that the extrusion body 104 in the rotating section 103 actively approaches the extrusion body 104 in the arc section 102. That is, the two extrusion bodies 104 approach each other and finally abut, thereby eliminating the gap between two adjacent extrusion bodies 104 in the arc section 102 and ensuring that several extrusion bodies 104 in the arc section 102 abut each other.

[0058] like Figure 5 As shown, the end of each extrusion body 104 facing the inner side of the rotary track 101 is set in a conical shape, and a rotating wheel 113 is rotatably set on the conical shape. By using the rotating wheel 113 in conjunction with the anti-push surface 111 and the side push surface 112 on the side push plate 109, the friction between the extrusion body 104 and the side push plate 109 can be reduced, thereby improving the stability of the structure operation.

[0059] Furthermore, such as Figure 8 As shown, the release unit 107 includes a support body 114 fixed relative to the rotary track 101. The side wall of the support body 114 facing the arc segment 102 is set as an arc surface 115, and the arc surface 115 is concentrically arranged with the arc segment 102. A transmission belt 116 is provided on the support body 114, and a plurality of buckles 117 are provided on the transmission belt 116. At least one of the buckles 117 is used in conjunction with the corresponding extrusion body 104.

[0060] The support body 114 provides support for the transmission belt 116 and allows the transmission belt 116 to rotate. To reduce friction, several rollers can be provided on the transmission belt 116. The rotational power of the transmission belt 116 can be provided by a drive motor and a power wheel connected to the transmission belt 116. The arc surface 115 corresponds to the arc segment 102, so that when the buckle plate 117 moves on the arc surface 115, the buckle plate 117 and the extrusion body 104 in the arc segment 102 can have the same movement trajectory, thereby achieving the synchronous movement effect of the buckle plate 117 and the extrusion body 104. When the several extrusion bodies 104 in the arc segment 102 move... They will move one by one to the area where the arc surface 115 is located. At this time, the corresponding buckle plate 117 on the arc surface 115 cooperates with the extrusion body 104 or the rotating wheel 113 on the extrusion body 104 and engages with each other. The extrusion body 104 and the buckle plate 117 move synchronously. When the extrusion body 104 moves to the tail of the arc surface 115, the buckle plate 117 separates from the extrusion body 104. At this time, the extrusion body 104 is released from the arc section 102 to the rotating section 103, thereby realizing the uniform movement and release of several extrusion bodies 104 in the arc section 102, ensuring that several extrusion bodies 104 in the arc section 102 can always abut against each other.

[0061] Furthermore, such as Figure 5 and Figure 9 As shown, the pushing unit 108 includes a rotating column 118 that rotates on a rotary track 101. A spiral groove 119 is provided on the outer wall of the rotating column 118. Each extrusion body 104 has a deflector 120 on its side wall that works in conjunction with the spiral groove 119. At least one deflector 120 exists on the spiral groove 119.

[0062] The rotating column 118 is rotatably mounted on the outer wall of the rotary track 101, and the rotation of the rotating column 118 can be powered by a drive motor, transmission wheel, and other structures. When the extrusion body 104 moves to the area where the rotating column 118 is located, the deflector 120 on the extrusion body 104 slides into the spiral groove 119 from one end. The rotation of the rotating column 118 will push the deflector 120 to move through the spiral groove 119, thereby pushing the extrusion body 104 to move within the arc segment 102, which facilitates the power supply for the cyclic movement of several extrusion bodies 104. When the deflector 120 moves to the other end of the spiral groove 119, the deflector 120 will separate from the rotating column 118. To ensure the continuity of power transmission, at least one deflector 120 must always be present in the spiral groove 119.

[0063] In practical use, since the spiral groove 119 does not need to cooperate with the pushers 120 on several extrusion bodies 104 in the arc section 102 at the same time, the length of the rotating column 118 does not need to be too large. It only needs to be able to cooperate with at least one pusher 120. The installation position of the rotating column 118 is generally located at the top of the arc section 102. This can actively pull the extrusion bodies 104 in the rotating section 103 into the arc section 102, so that the extrusion bodies 104 entering the arc section 102 are in the abutment state.

[0064] Furthermore, since the movement trajectory of the extruded body 104 within the arc-shaped segment 102 is arc-shaped, while the rotating column 118 is linear, if the pitch of the spiral groove 119 is constant, then when there are two pushers 120 on the spiral groove 119, the spiral groove 119 will have the same movement speed along the axis of the rotating column 118 provided by the two pushers 120. However, on the trajectory of the arc-shaped segment 102, there will be a speed difference between the two extruded bodies 104, resulting in a gap between the two extruded bodies 104. To avoid this phenomenon, such as... Figures 5 to 9 As shown, the pitch of the spiral groove 119 gradually decreases along the axis of the rotating column 118; the pusher column 120 is slidably mounted on the extrusion body 104 via the slide block 121, and the slide block 121 and the extrusion body 104 are connected by the elastic body 122.

[0065] When the rotating column 118 rotates at a constant speed, the first deflector 120 initially entering the spiral groove 119 will have a relatively high moving speed. At this time, the first deflector 120 will push the extrusion body 104 to abut against the extrusion body 104 in the arc-shaped section 102. Due to the limitation of the release unit 107, the moving speed of several extrusion bodies 104 in the arc-shaped section 102 is constant. Therefore, the moving speed of the extrusion body 104 corresponding to the spiral groove 119 is constant. That is, the extrusion body 104 and its upper deflector 120 will have relative motion. As the slide block 121 slides on the extrusion body 104, the elastic body 122 undergoes elastic deformation. As the pitch of the spiral groove 119 decreases, the moving speed of the pusher 120 gradually decreases, and the displacement of the pusher 120 on the extrusion body 104 gradually decreases. During this process, the two adjacent extrusion bodies 104 always remain in contact. Thus, the specially designed pusher unit 108 can keep the several extrusion bodies 104 on the arc segment 102 in contact with each other, avoiding gaps between the two adjacent extrusion bodies 104 when they move.

[0066] Furthermore, both rotary track 101 and rotary track 201 are provided with guide grooves. Both the side wall of extrusion body 104 and the side wall of extrusion body 204 are provided with several movable wheels 123 that cooperate with the guide grooves. The several movable wheels 123 are arranged in sequence, and adjacent movable wheels 123 are connected to each other through transmission. Adjacent movable wheels 123 are in transmission contact with the two inner side walls of the guide groove respectively.

[0067] like Figure 4 and Figure 5 As shown, when the extrusion body 104 moves along the trajectory of the rotary track 101, the moving wheel 123 rolls in the guide groove. By specially setting the relative positions of the moving wheels 123, the moving wheels 123 can be kept in a mutually engaged state with the guide groove, and adjacent moving wheels 123 will also support each other, thereby improving the stability of the movement of the extrusion body 104 and avoiding friction. In contrast, the traditional method of setting only one or one row of moving wheels 123 will cause the outer wall of the moving wheel 123 to contact both sides of the guide groove at the same time. At this time, the moving wheel 123 will inevitably rub against one side wall in the guide groove. The guide groove on the rotary track 201 and the corresponding moving wheel 123 have the same characteristics.

[0068] Furthermore, the auxiliary unit includes two inclined arms 124 that are rotatably connected to each other. The two inclined arms 124 are rotatably connected to two adjacent extrusion bodies 104 or two adjacent extrusion bodies 204 respectively, and a limiting body 125 is provided on one inclined arm 124 for limiting the opening angle of the two inclined arms 124.

[0069] like Figure 5 As shown, the rotation axis between the two inclined arms 124 and the rotation axis between the inclined arms 124 and the corresponding extrusion body 104 or extrusion body 204 are parallel to the axis of the arc segment 102. In this way, in the direction of the axis of the arc segment 102, the auxiliary unit will restrict the two adjacent extrusion bodies 104 or the two adjacent extrusion bodies 204. Furthermore, the change in the distance between the two adjacent extrusion bodies 104 or the two adjacent extrusion bodies 204 will cause the two inclined arms 124 to rotate relative to each other, and the included angle between the two inclined arms 124 will change. The inclined arms 124 of this structure will not occupy a large space and allow the distance between the two adjacent inclined arms 124 to vary within a large range. The setting of the limiting body 125 can prevent the two adjacent inclined arms 124 from rotating to a collinear state, thereby avoiding the reduction in the distance between the two extrusion bodies 104 caused by the two inclined arms 124 in this state, which would cause jamming.

[0070] Furthermore, the extrusion body 104 and the extrusion body 204 are respectively provided with protrusions 126 and slots 206 that cooperate with each other;

[0071] The second conveying structure 200 also includes a second pushing unit 210 for conveying the second extruded body 204 into the second arc-shaped section 202.

[0072] like Figure 4 and Figure 6 As shown, within the area of ​​the conveying channel, one extrusion body 104 corresponds to one extrusion body 204. At this time, the protrusion 126 will be inserted into the slot 206, thereby using the movement of extrusion body 104 to drive the movement of extrusion body 204. This makes it convenient for extrusion body 104 and extrusion body 204 to move synchronously, and it is not necessary to set up a separate power source for the movement of several extrusion bodies 204, simplifying the structure and improving the synchronicity of the structure operation.

[0073] Pushing unit 210 can deliver the extrusion body 204 in the rotary section 203 into the arc section 202, thereby eliminating the distance between two adjacent extrusion bodies 204. Specifically, for example... Figure 4 and Figure 10 As shown, the second pushing unit 210 includes a second detonator 207 disposed on the side wall of the second extrusion body 204, a power disk 208 rotatably disposed on the side wall of the second rotary track 201, and a plurality of levers 209 mounted on the power disk 208. When the power disk 208 and the plurality of levers 209 rotate, the levers 209 will move the second extrusion body 204 through the second detonator 207 and enter the arc-shaped section 202, thereby causing two adjacent extrusion bodies 204 to abut against each other in the arc-shaped section 202.

[0074] In some embodiments, to facilitate proper docking of the extrusion body 104 and extrusion body 204 initially entering the conveying channel, such as Figure 2 As shown, inclined sections 300 can be provided at the top of both the first arc section 102 and the second arc section 202. The inclined sections 300 can be used to straighten the orientation of the first extrusion body 104 and the second extrusion body 204 as they approach each other.

Accordingly, this specification and drawings are merely exemplary illustrations of the application as defined herein, and are to be considered as covering any and all modifications, variations, combinations, or equivalents within the scope of this application.
