[0054] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0055] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains.

[0056] The extruder of this application is used to extrude the periphery of a frame made of keel so that the dimensions of the frame after the core material is inserted match the dimensions of the sheet material. However, the extruder 100 of this application is not limited to extruding keel frames; other objects 7 that require periphery extrusion can also be extruded using this application.

[0057] This application achieves compression of the object 7 around it by sliding two first compression parts 2 on the support 1 along the first direction A and by arranging two second compression parts 4 opposite to each other on the support 1 along the second direction B.

[0058] Example 1

[0059] like Figures 1-4 As shown, Embodiment 1 of this application provides an extrusion press, comprising:

[0060] Bracket 1;

[0061] Two first extrusion parts 2 are slidably connected to the bracket 1 along the first direction B;

[0062] Two first driving parts 3 are connected to the bracket 1, each first driving part 3 is connected to a first extrusion part 2, and each first driving part 3 is used to drive a first extrusion part 2 to slide along the first direction A;

[0063] Two second extrusion sections 4 are disposed opposite to each other on the bracket 1 along the second direction B;

[0064] In this configuration, two second extrusion parts 4 form an inlet along the first side of the first direction A. The two second extrusion parts 4 and a portion of the two first extrusion parts 2 can form an extrusion area 5. The object to be extruded 7 can enter the extrusion area 5 through the inlet. The first direction A is perpendicular to the second direction B.

[0065] Specifically, the support 1 serves a supporting function. The length of the support 1 along the first direction A must be greater than the maximum dimension of the object 7 to be compressed along the first direction A, so that the two first compression parts 2 can slide on the support 1 along the first direction A and compress the object 7 to be compressed on both sides along the first direction A. The dimension of the support 1 along the second direction B must be referenced to the dimension of the object 7 to be compressed on the second direction B, so that the object 7 to be compressed can enter the compression area 5, and the two second compression parts 4 can compress the object 7 to be compressed on both sides along the second direction B. The specific structure of the support 1 is not further limited and can be designed according to the actual situation.

[0066] Two first pressing parts 2 are used to press the object 7 to be pressed on both sides along the first direction A. The specific arrangement of the two first pressing parts 2 is not further limited. For example, a slide rail 12 can be provided on the support 1 along the first direction A, with the slide rail 12 positioned on the side of the two second pressing parts 4 facing away from each other. Both first pressing parts 2 are slidably connected to the support 1 along the first direction A via the slide rail 12. Alternatively, two slide rails 12 extending along the first direction A can be provided on the support 1, with the two slide rails 12 facing each other along the second direction B. The two second pressing parts 4 are positioned between the two slide rails 12, with one first pressing part 2 slidably connected to each slide rail 12. The technician can choose according to the actual situation, as long as the two first pressing parts 2 can press the object 7 to be pressed on both sides along the first direction A; no further limitations are made here. The sliding of the two first pressing parts 2 on the support 1 via the slide rails 12 also ensures the stability of the sliding motion.

[0067] The first driving unit 3 is used to drive the first extrusion unit 2 to slide along the first direction A. The first driving unit 3 can be a linear motor, a cylinder or a hydraulic cylinder, and the driving axis of each first driving unit 3 is aligned with the first direction A. Each first driving unit 3 is connected to a first extrusion unit 2.

[0068] Two second extrusion sections 4 are used to extrude the object 7 along both sides of the second direction B. Each of the two second extrusion sections 4 has an inlet and an outlet on both sides of the first direction A. The object 7 is entered into the extrusion area 5 manually or via a conveyor belt from the inlet on the first side. After being extruded to the desired size by the two first extrusion sections 2 and the two second extrusion sections 4, it is capped, and then the capped product is output manually or via a conveyor belt from the outlet. When a conveyor is used to transport the object 7, the conveyor is positioned between the two second extrusion sections 4, and the conveyor's transport direction is the first direction A.

[0069] Compared to existing technologies, the extruder provided in this application slides two first extrusion sections 2 along the first direction A onto the support 1, and each first driving section 3 is connected to one of the first extrusion sections 2, thereby driving the first extrusion section 2 to slide along the first direction A; two second extrusion sections 4 are arranged opposite each other on the support 1 along the second direction B, and the two second extrusion sections 4 form an inlet on the first side along the first direction A, through which the object to be extruded 7 can enter the extrusion area 5. At this time, the first driving section 3 drives the first extrusion section 2 to move along the first direction A, thereby applying pressure to both sides of the object to be extruded 7 along the first direction A, and the application of pressure is more time-saving and labor-saving; at the same time, the two second extrusion sections 4 apply pressure to both sides of the object to be extruded 7 along the second direction B, thereby achieving circumferential extrusion of the object to be extruded 7. The extrusion machine of this application slides two first extrusion parts 2 on the support 1 along the first direction A, and two second extrusion parts 4 are arranged opposite each other on the support 1 along the second direction B. The two first extrusion parts 2 and the two second extrusion parts 4 extrude the circumference of the object to be extruded 7, thereby ensuring that the size of the frame is consistent with the size of the core material, and ensuring the final capping effect.

[0070] like Figure 1 and Figure 2 As shown, in some embodiments, both of the first extrusion portions 2 include a first mounting base 21 and an extrusion rod 22;

[0071] The first mounting base 21 is slidably connected to the bracket 1 along the first direction A. The length direction of the extrusion rod 22 is consistent with the second direction B. The first end of the extrusion rod 22 is rotatably connected to the first mounting base 21. The rotation axis of the extrusion rod 22 is consistent with the first direction A. The extrusion rod 22 and the two second extrusion parts 4 can form the extrusion area 5.

[0072] Specifically, the first mounting base 21 can be slidably connected to the bracket 1 via the slide rail 12. The extrusion rods 22 on the two first extrusion parts 2 are used to extrude the object 7 to be extruded along both sides of the first direction A. It should be noted that the extrusion rods 22 can also be replaced with extrusion plates, etc., as long as the structure can achieve the extrusion of the object 7 to be extruded along both sides of the first direction A, which will not be elaborated here.

[0073] The length of the extrusion rod 22 is limited according to the dimension of the object 7 to be extruded along the second direction B. The two extrusion rods 22 can extend between the two second extrusion sections 4, forming the extrusion area 5 together with the two second extrusion sections 4.

[0074] To facilitate the entry and exit of the object to be squeezed 7 into and out of the squeezing area 5, two first squeezing parts 2 can be designed to move relative to two second squeezing parts 4 along a third direction C. For example, the support 1 includes a third sub-support and a fourth sub-support. Both first squeezing parts 2 include a second linear actuator. The second linear actuator is connected to the third sub-support, and its drive end is connected to the fourth sub-support. The drive axis of the second linear actuator is aligned with the third direction C. The second linear actuator is used to drive the fourth sub-support to reciprocate along the third direction C, thereby driving the two first squeezing parts 2 on the fourth sub-support to move.

[0075] The first mounting base 21 is slidably connected to the fourth sub-support along the first direction A. When the object to be squeezed 7 is squeezed, the fourth sub-support moves towards the third sub-support, so that the two first squeezing parts 2 squeeze the two sides of the object to be squeezed 7 along the first direction A; when the object to be squeezed 7 enters or leaves the squeezing area 5, the fourth sub-support moves away from the third sub-support, so that the two first squeezing parts 2 do not contact the object to be squeezed 7, which facilitates the entry and exit of the object to be squeezed 7.

[0076] In some embodiments, each of the two first extrusion sections 2 further includes a first linear actuator 23;

[0077] The first linear actuator 23 is mounted on the first mounting base 21. The drive axis of the first linear actuator 23 has a preset angle with the plane containing the first direction A and the second direction B. The drive end of the first linear actuator 23 is connected to the first end of the extrusion rod 22 and is used to drive the extrusion rod 22 to rotate around the first direction A.

[0078] Specifically, the first linear actuator 23 can be a linear motor, a pneumatic cylinder, or a hydraulic cylinder. The first linear actuator 23 can be fixedly connected to the first end of the pressing rod 22 by bolts. During operation, the driving axis of the first linear actuator 23 has a preset angle with the plane containing the first direction A and the second direction B. This preset angle can be designed according to actual conditions. During extension and retraction, the first linear actuator 23 can drive the pressing rod 22 to rotate around the first direction A. The specific angle of rotation can be controlled according to the distance of extension and retraction of the first linear actuator 23.

[0079] In some embodiments, each of the two first extrusion sections 2 further includes a first motor (not shown in the figure);

[0080] The first motor is mounted on the first mounting base 21, the drive end of the first motor is connected to the first end of the extrusion rod 22, and the drive axis of the first motor is aligned with the first direction A.

[0081] Specifically, the first end of the extrusion rod 22 has a mounting hole along the first direction A. A first rotating shaft passes through the mounting hole and is fixedly connected to the first end of the extrusion rod 22. Both ends of the first rotating shaft are rotatably connected to the first mounting base 21. A first motor is mounted on the first mounting base 21, and the output end of the first motor is connected to the first rotating shaft. The drive axis of the first motor is aligned with the first direction A. The first motor is used to drive the first rotating shaft to rotate, thereby causing the extrusion rod 22 to rotate around the first direction A.

[0082] like Figure 1 and Figure 2 As shown, in some embodiments, both of the first drive units 3 include a second motor;

[0083] The bracket 1 is provided with a rack 11 along the first direction A, and the rack 11 is located on the side of the two second pressing parts 4 facing away from each other; the second motor is provided on the first mounting base 21, and the output end of the second motor meshes with the rack 11.

[0084] In some embodiments, the first drive unit 3 includes a second linear actuator;

[0085] The second linear actuator is mounted on the bracket 1, and the drive end of the second linear actuator is connected to the first mounting base 21. The drive axis of the second linear actuator is aligned with the first direction A.

[0086] Specifically, the support 1 may include a strip plate disposed on the side opposite to the two extrusion parts. A slide rail 12 is provided on each of the two first sides of the strip plate along a first direction A to ensure the stability of the sliding of the two first extrusion parts 2. The two first sides of the strip plate are two sides along a third direction C. A rack 11 is provided on the second side of the strip plate along the first direction A, and the second side of the strip plate is away from the two second extrusion parts 4. The first mounting plate may be U-shaped, and the first mounting plate is slidably connected to the strip plate along the first direction A via two slide rails 12. The output shaft of the second motor is fixedly connected to an external gear to form the output end of the second motor, and the external gear meshes with the rack 11. The rotation of the second motor allows the first mounting base 21 to move along the first direction A on the strip plate, thereby realizing the movement of the two first extrusion parts 2 along the first direction A, achieving extrusion of the object 7 to be extruded along both sides of the first direction A, making extrusion more time-saving and labor-saving. Alternatively,

[0087] The rack 11 and the second motor are replaced by a third linear actuator. Two third linear actuators are respectively installed at both ends of the strip plate along the first direction A. The drive end of each third linear actuator is connected to a first mounting base 21, thereby realizing the movement of the two first extrusion parts 2 along the first direction A, and realizing the extrusion of the object to be extruded 7 on both sides along the first direction A.

[0088] To prevent wear on the object 7 to be extruded from the two second extrusion sections 4 during the extrusion process, each second extrusion section 4 may include multiple sets of wheels arranged along the first direction A. These multiple sets of wheels are all mounted on the support 1, and the rotation axis of each set is in the third direction C. To ensure the extrusion effect, the multiple sets of wheels in the two second extrusion sections 4 correspond one-to-one. Furthermore, the distance between the sets of wheels at the inlets of the two second extrusion sections 4 is greater than the distance between the sets of wheels at the outlets of the two second extrusion sections, so that the object 7 to be extruded can enter the extrusion area 5. This rolling contact reduces wear on the object 7 to be extruded from the second extrusion sections 4.

[0089] In practical use, to improve work efficiency, a material conveyor 200 can be installed between the two second extrusion sections 4, with the material conveyor 200 moving in the same direction as the first direction A. This is to further reduce the wear caused to the object 7 being extruded by the two second extrusion sections 4. Figure 1 and Figure 3 As shown, in some embodiments, each of the two second pressing sections 4 includes a third motor, a chain ring 41, a first external toothed ring, and a pressing block 42;

[0090] The third motor is mounted on the bracket 1, the first external gear ring is rotatably connected to the bracket 1, the third motor and the second external gear ring are spaced apart along the first direction A, the inner side of the chain ring 41 meshes with the output end of the third motor and the first external gear ring respectively, and the pressure block 42 is mounted on the outer side of the chain ring 41.

[0091] The third motors of the two second extrusion sections 4 are opposite each other along the second direction B, the first external gear rings of the two second extrusion sections 4 are opposite each other along the second direction B, and the distance between the first external gear rings of the two second extrusion sections 4 is greater than or less than the distance between the third motors.

[0092] The third motors of the two second extrusion sections 4 synchronously drive the chain ring 41 to move, so that the pressing blocks 42 of the two second extrusion sections 4 are always opposite each other along the second direction B.

[0093] Specifically, to accommodate the shape of the frame structure to be compressed in this application, the third motor and the first external gear ring allow the chain ring 41 to form an ellipse, with its major axis aligned with the first direction A. However, in practical applications, the spacing between the third motor and the first external gear ring can be designed according to the actual shape of the object to be compressed 7 to adjust the shape of the chain ring 41, thereby adapting to objects 7 of different sizes. To ensure the continuity of the operation and the compression effect, multiple pressure blocks 42 can be set, for example, two, three, four, five, six, seven, eight, nine, ten, etc., the specific number of which can be designed according to the length of the object to be compressed 7 along the first direction A. Multiple pressure blocks 42 are evenly spaced on the outside of the chain ring 41.

[0094] The distances between the third motors of the two first extrusion sections 2 and the first external gear ring are not equal. The side with the larger distance is the first side of the two first extrusion sections 2 and forms an inlet. For example, when the distance between the third motors of the two first extrusion sections 2 is greater than the distance between the first external gear ring, the object 7 to be extruded enters the extrusion area 5 from the end with the third motor of the two extrusion sections. In this case, the end with the third motor is the inlet of the first side of the two first extrusion sections 2, or vice versa.

[0095] The first external gear ring can be rotatably connected to the bracket 1 via the second rotating shaft 8. To further ensure the extrusion effect, both second extrusion sections 4 include a second external gear ring, which is positioned between the third motor and the first external gear ring. The second external gear ring meshes with the chain ring 41. The second external gear rings of the two second extrusion sections 4 are arranged opposite each other along the second direction B. When the distance between the third motors of the two first extrusion sections 2 is greater than the distance between the first external gear rings, the distance between the second external gear rings of the two second extrusion sections 4 is equal to the distance between the first external gear rings, which is more conducive to the extrusion of the rectangular object 7 to be extruded in this application.

[0096] To simplify the overall structure, reduce production costs, and facilitate the synchronous control of the two chain rings 41 of the two subsequent second extrusion sections 4, the two second extrusion sections 4 can share a single third motor. For example, the output end of the third motor meshes with the chain ring 41 of one second extrusion section 4, and simultaneously, the output end of the third motor meshes with the chain ring 41 of the other second extrusion section 4 via a transmission mechanism. This transmission mechanism is mounted on a support and can include multiple gears, chains, etc. Its specific structure is not further limited; technicians can design it according to actual conditions, as long as it enables the two chain rings to move synchronously and in the same direction, allowing the two chain rings 41 to remain relatively stationary during movement.

[0097] In actual operation, by controlling the conveying speed of the third motor and the material conveyor 200, the pressure block 42 on the chain ring 41 that is in contact with the object to be squeezed 7 has no relative movement with the object to be squeezed 7, thus avoiding wear on the surface of the object to be squeezed 7 caused by the pressure block 42 and ensuring the quality of the final product.

[0098] To accommodate objects 7 of different sizes to be extruded and improve the practicality of the extruder, the distance between the two second extrusion sections 4 can be adjusted. For example, the support 1 includes a first sub-support and a second sub-support, which are arranged opposite each other along the second direction B. The first sub-support and / or the second sub-support can slide back and forth along the second direction B. For example, casters and a first locking part can be provided at the bottom of the first sub-support and / or the second sub-support. The first sub-support and / or the second sub-support can be driven to slide back and forth along the second direction B manually or automatically, thereby adjusting the distance between the two second extrusion sections 4 on the first sub-support and the second sub-support, and fixing the distance between the first sub-support and the second sub-support by the first locking part; or, the support 1 can also include a fifth sub-support, which has a slide rail and a second locking part along the second direction B. The first sub-support and / or the second sub-support are slidably connected to the fifth sub-support along the second direction B through the slide rail, and the distance between the two first sub-supports and the second sub-support is fixed by the second locking part. This sliding can also be done manually or automatically, depending on the actual situation.

[0099] To simplify the overall structure of the extruder and make it easier for operators to operate, such as... Figure 1 and Figure 5 As shown, in some embodiments, a second driving unit 9 is also included;

[0100] The bracket 1 includes a first sub-bracket and a second sub-bracket. The first sub-bracket and the second sub-bracket are arranged opposite to each other along the second direction B. A second compression part 4 is provided on the first sub-bracket and the second sub-bracket respectively.

[0101] The second driving part 9 is disposed on the second sub-support, and the driving end of the second driving part 9 is connected to the first sub-support. The second driving part 9 is used to drive the first sub-support to move towards or away from the second sub-support.

[0102] Specifically, the second sub-support can be fixedly supported on the support surface by bolts or the like. The second drive unit 9 can be a linear motor, a cylinder, or a hydraulic cylinder, etc., and its drive shaft axis is aligned with the second direction B. Alternatively, the second drive unit 9 can include a fourth motor and a linkage structure. The fourth motor is fixedly mounted on the second sub-support, and the rotation axis of the fourth motor is aligned with the third direction C. The linkage structure includes a first rod 91 and a second rod 92, with the first end of the first rod 91 and the first end of the second rod 92 rotatably connected. There is a preset included angle between the first rod 91 and the second rod 92, and the drive end of the fourth motor is fixedly connected to the second end of the first rod 91.

[0103] When only one third motor is provided for each of the two second extrusion sections 4, the transmission mechanism can be set on the linkage structure. Specifically, a second rotating shaft 8 is rotatably connected to both the first and second sub-supports. One end of the second rotating shaft 8 on the first sub-support is fixedly connected to the first external gear ring, and the other end passes through the first sub-support and is rotatably connected to the second end of the second rod; one end of the second rotating shaft 8 on the second sub-support meshes with the chain ring 41, and the other end passes through the second sub-support and the second end of the first rod 91 in sequence, and is connected to the drive end of the third motor. The transmission mechanism is set on the linkage structure and is connected to the second rotating shaft 8 on the first and second sub-supports respectively. The third motor and the fourth motor are arranged alternately.

[0104] When the material conveyor 200 conveys the object 7 to be extruded, the first sub-support can be provided with through holes along the second direction B. Multiple through holes are arranged at equal intervals along the first direction A on the first sub-support. The first sub-support is rotatably connected to a portion of the shaft of the material conveyor 200 through the through holes and can slide along the second direction B on that portion of the shaft. To ensure the stability of the sliding, multiple second drive units 9 can also be provided as needed, spaced apart along the length of the second extrusion section 4. For example, two second drive units 9 can be provided, respectively located at both ends of the second extrusion section 4 along its length. Alternatively, three, four, five, or more can be provided as needed.

[0105] During operation, the rotation of the fourth motor can increase or decrease the preset angle between the first rod 91 and the second rod 92, thereby increasing or decreasing the distance between the first support and the second sub-support. It should be noted that this application is only required to achieve adjustable spacing between the two first pressing parts 2, and is not limited to the specific embodiments described above.

[0106] like Figure 1 and Figure 4 As shown, in some embodiments, a roller group 6 is also included;

[0107] The roller group 6 is connected to the bracket 1, and the rotation axis of the roller 61 of the roller group 6 is consistent with the second direction B; the roller 61 and the two first extrusion parts 2 are at a preset distance along the third direction C, and the third direction C is perpendicular to the first direction A and the second direction B respectively;

[0108] There is one roller group 6, which is disposed on one side of the two second extrusion sections 4 along the first direction A; or

[0109] There are two roller groups 6, and the two roller groups 6 are respectively arranged on both sides of the two second extrusion sections 4 along the first direction A.

[0110] Specifically, roller group 6 is used to press the object 7 to be pressed along the third direction C, making the surface of the object 7 to be pressed smoother. In order to ensure the pressing effect of roller group 6, the length of roller 61 of roller group 6 should not be less than the dimension of the object 7 to be pressed along the second direction B.

[0111] Roller groups 6 can be set one, two, three, four, etc. When there is only one roller group 6, it can be set at the inlet of the two second extrusion sections 4 to make the object 7 to be extruded flatter and facilitate subsequent capping. When the roller group 6 is set at the outlet of the two second extrusion sections 4, it can make the capped object flatter and facilitate subsequent processing. When two roller groups 6 are set, one roller group 6 can be set at each of the inlet and outlet. The specific position of the roller group 6 can be selected according to actual needs. In addition, different numbers of roller groups 6 can be added to both sides of the second extrusion section 4 along the first direction A, as needed.

[0112] When the distance between the two second extrusion sections 4 is adjustable, the length of the roller 61 in the roller group 6 should be greater than or equal to the maximum distance between the two second extrusion sections 4, so as to achieve extrusion of objects 7 of different sizes.

[0113] like Figure 1 and Figure 4 As shown, in some embodiments, the roller group 6 includes a second mounting base 62, a connector 63, and a spring 64;

[0114] The second mounting base 62 is disposed on the bracket 1, and the connecting member 63 is slidably connected to the second mounting base 62 along the third direction C. The connecting member 63 is rotatably connected to both ends of the roller 61. A spring 64 is disposed on the second mounting base 62 along the third direction C, and the connecting member 63 can compress the spring 64 by sliding along the third direction C.

[0115] Specifically, the middle part of the connector 63 has a through hole along the second direction B, and both ends of the roller 61 pass through the through hole and are rotatably connected to the connector 63. When the size of the object 7 to be squeezed changes significantly along the third direction C, the roller 61 will also drive the connector 63 to move along the third direction C on the second mounting base 62 while rotating. During the movement, the connector 63 compresses the spring 64, which buffers the force received and extends the service life of the roller group 6.

[0116] Example 2

[0117] like Figures 1-10 As shown, Embodiment 2 of this application provides a production line, including:

[0118] The extruder 100 of Example 1;

[0119] 200 incoming material conveyor; and

[0120] Flipping machine 300;

[0121] The material conveyor 200 is arranged between the two second extrusion sections 4 of the extruder 100. The material conveyor 200 moves in the first direction A. Roller groups 6 are respectively arranged on both sides of the extrusion section along the first direction A. The flipping machine 300 is arranged at intervals with the extruder 100 along the second direction B. The first direction A is perpendicular to the second direction B.

[0122] The control unit is connected to the flipping machine 300, the material conveyor 200 and the extruder 100 respectively, and is used to control the flipping machine 300, the material conveyor 200 and the extruder 100 to move synchronously.

[0123] During operation, the flipper 300 grabs and flips the conveyed sheet metal, while the feed conveyor 200 transports the object to be squeezed 7 above the squeezing area 5. Two first squeezing sections 2 and two second squeezing sections 4 squeeze the object 7. During the squeezing process, the feed conveyor 200 continuously transports the object 7 along the first direction A, while the two first squeezing sections 2 also move synchronously along the first direction A, continuously squeezing the object 7. At this time, the flipper 300 also moves along the first direction A. The control unit controls the conveying speed of the feed conveyor 200 and the movement speed of the two first squeezing sections 2 to be the same as the flipper 300's movement speed along the first direction A, ensuring that there is no relative movement between the feed conveyor 200, the two first squeezing sections 2, and the flipper 300 along the first direction A. Then, the cover is closed, achieving continuous automated production and greatly improving work efficiency.

[0124] Compared to the prior art, the production line provided in Embodiment 2 of this application includes the extruder 100 provided in Embodiment 1. The extruder 100 slides two first extrusion parts 2 along the first direction A on the support 1, and each first driving part 3 is connected to one of the first extrusion parts 2, thereby driving the first extrusion parts 2 to slide along the first direction A. Two second extrusion parts 4 are arranged opposite to each other on the support 1 along the second direction B. The two second extrusion parts 4 form an inlet on the first side along the first direction A, and the object to be extruded 7 can enter the extrusion area 5 through the inlet. At this time, the first driving part 3 drives the first extrusion parts 2 to move along the first direction A, thereby applying pressure to both sides of the object to be extruded 7 along the first direction A, and the application of pressure is more time-saving and labor-saving. At the same time, the two second extrusion parts 4 apply pressure to both sides of the object to be extruded 7 along the second direction B, thereby achieving circumferential extrusion of the object to be extruded 7. The extruder 100 of this application comprises two first extrusion sections 2 slidably connected on a support 1 along a first direction A, and two second extrusion sections 4 oppositely arranged on the support 1 along a second direction B. The two first extrusion sections 2 and the two second extrusion sections 4 extrude forcefully around the object 7 to be extruded, thereby ensuring that the dimensions of the frame are consistent with the dimensions of the core material, thus guaranteeing the final capping effect. The production line of this application, through the cooperation of the flipping machine 300, the material conveyor 200, and the extruder 100, can achieve continuous automated production, greatly improving work efficiency.

[0125] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
