[0052] Please refer to Figure 1 A hollow lattice plate co-extrusion coating discharging device is shown, comprising:

[0053] The main feeding mechanism 30 is used for extruding the first material, and the discharge end is communicated with the mixing box 40.

[0054] The auxiliary feeding mechanism 50 is used for extruding the second material, and the discharge end is communicated with the mixing box 40.

[0055] The extrusion die 60 is communicated at the discharge end of the mixing box 40.

[0056] On the discharge direction side of the extrusion die 60, the shaping mechanism 70, the conveying roller mechanism 80 and the cutting mechanism 90 are sequentially arranged along the material conveying direction.

[0057] In this way, in the process of extrusion, the first material and the second material are respectively extruded into the mixing box 40 through the main feeding mechanism 30 and the auxiliary feeding mechanism 50, and after the multi-layer superposition is completed in the mixing box 40, the profiled lattice plate is shaped through the extrusion die 60, and then enters the shaping mechanism 70 for plate shaping. After the material is completely cooled on the long-distance conveying roller mechanism 80, the long strip plate is cut to a fixed length through the cutting mechanism 90. Through the conveying of the long-distance conveying roller mechanism 80, the plate can be completely cooled, so as to avoid the situation that the cutting surface is difficult to cut off and the cutting edge is severely extruded and deformed because the plate is not completely cooled when cutting.

[0058] Further, please combine the drawings shown in Figures 2 to 5 The shaping mechanism 70 includes a walking assembly 11 movably installed on a walking frame 12.

[0059] A bottom frame assembly 13 is installed on the top surface of the walking assembly 11, and a lower water-cooled shaping die 14 is installed.

[0060] A lifting assembly 15 is installed on the top surface of the bottom frame assembly 13, and a lifting end of the lifting assembly 15 is installed with a lifting table 16 parallel to the lower water-cooled shaping die 14.

[0061] An upper water-cooled shaping die 17 is constructed on one side of the lifting table 16 facing the lower water-cooled shaping die 14, and is connected with the lifting table 16 through a positioning support assembly 18.

[0062] The bottom end of the positioning support assembly 18 is detachably connected with the top surface of the upper water-cooled shaping die 17, and the top side of the positioning support assembly 18 is detachably connected with the lifting table 16 through a positioning flange 19.

[0063] The upper water-cooled shaping die 17 is connected with the lifting table 16 through a plurality of mutually parallel positioning support assemblies 18.

[0064] In this way, the material is cooled by passing through the gap between the upper water cooling forming die 17 and the lower water cooling forming die 14 during cooling. The lifting assembly 15 is used to adjust the distance between the upper water cooling forming die 17 and the lower water cooling forming die 14. During installation of the upper water cooling forming die 17, the positioning support assembly 18 is fixed with the upper water cooling forming die 17, and the cooperation between the positioning support assembly 18 and the limiting flange is used to ensure that the length of the positioning support assembly 18 between the bottom surface of the lifting platform 16 and the upper water cooling forming die 17 is the same after each support assembly is connected with the lifting platform 16 during installation, so as to ensure that the upper water cooling forming die 17 and the lifting platform are in a parallel state, and the upper water cooling forming die 17 and the lower water cooling forming die 14 are kept in a horizontal state when the lifting platform and the lower water cooling forming die 14 are kept in a horizontal state, thereby ensuring the uniform cooling effect of the material.

[0065] More specifically, the positioning support assembly 18 comprises a support rod 110, the two end sidewalls of the support rod 110 are respectively provided with a first thread 111 and a second thread 112, the top surface of the upper water cooling forming die 17 is provided with a plurality of thread holes with the same depth and matched with the first thread 111, and the bottom end of the support rod 110 is fitted into the thread hole and abuts against the bottom surface of the thread hole.

[0066] The lifting platform 16 is provided with a plurality of through holes, the second thread 112 of the support rod 110 passes through the through holes, the positioning flange 19 is installed on the second thread 112, and the positioning flange 19 is connected with the lifting platform 16 through bolt positioning.

[0067] The part of the support rod 110 provided with the second thread 112 is coaxially provided with a limiting disc 113, the outer diameter of the limiting disc 113 is smaller than the inner diameter of the through hole, and the limiting disc 113 is used to limit the fitting depth of the positioning flange 19.

[0068] In this way, the thread holes with the same depth are used to ensure that the support rod 110 fitted into the top surface of the upper water cooling forming die 17 has the same length, thereby ensuring the installation accuracy. Meanwhile, the limiting disc 113 provided on the support rod 110 is used to pass through the through hole on the lifting platform 16 during assembly, and then the limiting disc 113 is used to limit the fitting depth of the positioning flange 19 in the second thread 112, thereby ensuring that the distance between each positioning flange 19 and the upper water cooling forming die 17 is the same, so as to ensure that the distance between the upper water cooling forming die 17 and the lifting platform 16 is the same after the positioning flange 19 is connected with the lifting platform 16.

[0069] Specifically, the positioning flange plate 19 comprises a circular disc body 114, a vertical stepped hole is coaxially arranged on the disc body 114, the stepped hole comprises a first hole 115, a second hole 116 and a third hole 117 from top to bottom, the inner wall of the first hole 115 is provided with a threaded groove matched with the second thread 112, the second thread 112 is threadedly connected with the first hole 115, the inner diameter of the third hole 117 is the same as the outer diameter of the limiting disc 113, and the abutting table 118 is formed between the second hole 116 and the third hole 117, when the abutting table 118 abuts against the top surface of the limiting disc 113, the bottom surface of the limiting disc 113 is in the same plane as the bottom surface of the disc body 114.

[0070] In this way, the threaded groove in the inner wall of the first through hole is matched with the second thread 112, the connection between the disc body 114 and the support rod 110 is realized, and the disc body 114 is positioned along the axis direction of the support rod 110 by the threaded connection, so that after the disc body 114 is positioned and connected with the lifting table 16, the lifting table 16 can drive the support rod 110 to move up and down.

[0071] Meanwhile, the abutting table 118 formed by the third hole 117 and the second hole 116 can enable the limiting disc 113 to limit the disc body 114 from being installed too much, and the third hole 117 can provide a space for the limiting disc 113, so that the bottom surface of the disc body 114 can abut against the bottom surface of the lifting table 16 in the limiting state.

[0072] Furthermore, the support rod 110 is also provided with a pressing reinforcing nut 119 through the second thread 112, the bottom surface of the pressing reinforcing nut 119 abuts against the top surface of the disc body 114, and the outer diameter of the bottom surface of the pressing reinforcing nut 119 is greater than the inner diameter of the third hole 117.

[0073] Due to the stepped hole, the contact area of the threaded connection between the disc body 114 and the support rod 110 is small, and the pressing reinforcing nut 119 is arranged to abut against the top surface of the disc body 114, so as to increase the bearing capacity of the disc body 114.

[0074] Meanwhile, a plurality of first positioning holes 120 are arranged around the axis of the disc body 114, the inner wall of the first positioning hole 120 is provided with a threaded groove, a first pressing bolt is arranged in the first positioning hole 120, and the disc body 114 is positioned and connected with the top surface of the lifting table 16 through the first pressing bolt.

[0075] Furthermore, in order to increase the stability of the combination between the support column and the upper water-cooled sizing mold 17, a reinforcing flange 121 is threadedly installed at the bottom end of the support rod 110 at the position of the first thread 111, the bottom surface of the reinforcing flange 121 is arranged in abutment with the top surface of the lifting platform 16, a second positioning hole 122 is formed in the disc surface of the reinforcing flange 121, a threaded groove is formed in the second positioning hole 122, and a second compression bolt is threadedly installed in the second positioning hole 122, the reinforcing flange 121 and the top surface of the upper water-cooled sizing mold 17 are positioned and connected by the second compression bolt.

[0076] Furthermore, in order to be able to adjust the limiting distance of the disc body 114, the limiting disc 113 is threadedly installed on the second thread 112, and the surface of the support rod 110 at the position of the second thread 112 is provided with scale marks.

[0077] Further, by adjusting the position of the limiting disc 113 on the second thread 112, the limiting distance of the limiting disc 113 to the disc body 114 can be adjusted, and the scale marks are used to ensure that the limiting disc 113 on each different support rod 110 is arranged at the same position.

[0078] In addition, please refer to Figures 6 to 11 As shown in the figure, the cutting mechanism 90 includes a working mechanism 21, which is configured with a clamping passage for the passage of the sheet, and a movable cutter 22 arranged in the clamping passage and moving up and down;

[0079] A workbench 23 is arranged on the top surface of the working mechanism 21 and is provided with a linear slide rail 24, and the working mechanism 21 is installed on the linear slide rail 24;

[0080] A vertically movable linear air cylinder 25 is installed on the top surface of the working mechanism 21, and the extension end of the linear air cylinder 25 is connected with the top surface of the movable cutter 22;

[0081] The movable cutter 22 includes a positioning portion connected with the extension end of the linear air cylinder 25 and a cutting end arranged on the bottom surface of the positioning portion, the cutting end faces downward, and the moving direction of the cutting end is parallel to the moving direction of the sheet.

[0082] In this way, the long strip-shaped material passes through the clamping channel on the working mechanism 21, and then the linear cylinder 25 on the top surface of the working mechanism 21 is periodically opened, so that the cutting end of the movable cutter 22 cuts the long strip-shaped plate. During the cutting process, when the cutting end contacts the top surface of the plate, the plate can drive the cutting end to move together due to the interaction between the cutting end and the plate. During the movement, the cutting end can also cut the plate by using the downward pressure of the positioning part, so that the cutting end and the plate can be cut in a relatively static state, thereby ensuring the verticality and flatness of the cutting surface of the plate. Moreover, even if the cutting speed is slow, the cutting effect of the plate can be ensured without the need for fast cutting, which is helpful for the protection of the cutting end and can improve the service life of the cutting end. Moreover, a linear cylinder 25 with high performance is not required, which reduces the cost and improves the service life of the linear cylinder 25.

[0083] Further, the movable cutter 22 includes a vertical plate 26 as the positioning part, the top surface of the vertical plate 26 is fixedly connected with the extension end of the linear slide rail 24, the bottom surface of the vertical plate 26 is provided with a horizontal positioning plate 27, the bottom surface of the positioning plate 27 is provided with a movable groove 28, and the blade 29 as the cutting end is slidably installed in the movable groove 28 through a movable reset mechanism.

[0084] In this way, the linear cylinder 25 controls the up-down movement of the vertical plate 26 during operation to control the blade 29 acting on the sheet to cut the sheet, and the blade 29 can move in the movable groove 28 under the action of the movable reset mechanism, so as to ensure that the blade 29 and the sheet remain relatively static in the horizontal direction during the cutting process. Thus, the cutting quality is ensured.

[0085] More specifically, the two inner walls of the movable groove 28 are provided with a sliding groove 210 parallel to the moving direction of the sheet, the movable reset mechanism is arranged in the sliding groove 210, and the sliding part side surface of the movable reset mechanism is connected with the side surface of the blade 29.

[0086] Specifically, for the movable reset mechanism, the movable reset mechanism comprises a sliding block 211 slidingly arranged in the sliding groove 210, the sliding block 211 is connected with the side wall of the blade 29, a limiting rod 212 parallel to the extending direction of the sliding groove 210 is arranged in the sliding groove 210, the limiting rod 212 horizontally penetrates through the sliding block 211, the limiting rod 212 is slidingly connected with the sliding block 211, a compression spring 213 is sleeved on the limiting rod 212, two ends of the compression spring 213 are respectively abutted with the sliding block 211 and the side wall of the sliding groove 210, and the compression spring 213 is arranged on the side of the sliding block 211 away from the sheet entering direction.

[0087] In this way, during the cutting process, when the blade 29 contacts the sheet, the blade 29 moves along with the sheet with the movement of the sheet and the extension of the blade 29, so that the compression spring 213 is continuously compressed. When the cutting is completed, during the upward movement of the blade 29, when the blade 29 is out of contact with the sheet, the sliding block 211 is pushed back under the action of the compression spring 213, so as to reset the blade 29. The limiting rod 212 is used to avoid the swing of the blade 29 during the cutting process, which affects the cutting effect.

[0088] Further, in order to avoid the sliding block 211 from colliding with the inner wall of the sliding groove 210 after resetting, a rubber pad 214 is arranged on the side of the sliding groove 210 facing the sheet entering direction. Then, the rubber pad 214 is used to buffer the sliding block 211.

[0089] Further, in order to reduce the friction between the upper and lower surfaces of the sliding block 211 and the sliding groove 210, the upper and lower surfaces of the sliding block 211 are respectively provided with open spherical cavities 215, a steel ball 216 is rotatably arranged in each spherical cavity 215, and the outer wall of the steel ball 216 partially protrudes out of the spherical cavity 215 and slidingly abuts against the top surface or the bottom surface of the sliding groove 210.

[0090] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model shall be included in the protection scope of the utility model.
