DETAILED DESCRIPTION

[0028] The technical scheme in the embodiment of the present invention is described clearly and completely below in conjunction with the accompanying drawings in the embodiment of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0029] See also Figure 1 to Figure 2 As shown, a rubber electromagnetic shielding sealing material production equipment includes a control cabinet 1 and an extruder body. The extruder body is used to extrude a uniformly mixed semi-finished material (rubber electromagnetic shielding sealing material). The extruder body is fixedly mounted above the control cabinet 1 and electrically connected to the control cabinet 1. The control cabinet 1 is used to drive the extruder body to operate. In this embodiment, the extruder body is fixedly connected to the control cabinet 1 through a first support assembly 7. Specifically, the first support assembly 7 includes an L-shaped plate 71, the lower part of the L-shaped plate 71 is a horizontal plate, which is fixedly connected to the top surface of the control cabinet 1 by bolts, and the upper part of the L-shaped plate is a vertical plate, which is fixedly connected to the extruder body by bolts. Preferably, reinforcing plates 72 are respectively fixed on both sides of the L-shaped plate to increase the strength of the L-shaped plate.

[0030] Preferably, a second support assembly 8 is further provided on one side of the top surface of the control cabinet 1, and the second support assembly 8 comprises a sleeve 81 fixed on one side of the top of the control cabinet 1, a support rod 82 slidably inserted in the sleeve 81, and a support plate 83 fixed on the top of the support rod 82, wherein the support plate 83 is used to support the bottom surface of one side of the extruder body to make the extruder body more stable, and the support rod 82 is a threaded rod 5232, and a nut 84 is screwed on the support rod 82 between the sleeve 81 and the support plate 83. During implementation, the nut 84 is rotated to adjust the relative position between the support rod 82 and the sleeve 81, thereby adjusting the abutment strength between the support plate 83 and the extruder body.

[0031] In this embodiment, the extruder body includes a charging barrel 2, a piston assembly 3, a reduction motor 4, a connector assembly 5 and a quantitative feeding assembly 6. The charging barrel 2 is a cylindrical barrel with a hollow interior and an open end. The piston assembly 3 is slidably arranged inside the charging barrel 2 for extruding the mixed semi-finished material. One end of the piston assembly 3 passes through one end of the charging barrel 2 and extends in a direction away from the charging barrel 2. A reduction motor 4 is fixed at one end of the charging barrel 2 for driving the piston assembly 3 to move, that is, one end of the piston assembly 3 is connected to the reduction motor 4 so that the reduction motor 4 can drive the piston assembly 3 to move along the axial direction of the charging barrel 2.

[0032] Specifically, the piston assembly 3 includes a plug rod 31 and a plug head 32. The plug head 32 is located inside the charging barrel 2 and is slidably connected to the inner wall of the charging barrel 2. The plug rod 31 is a threaded rod 5232. One end of the plug rod 31 is rotatably connected to the plug head 32. The other end of the plug rod 31 passes through the charging barrel 2 and the reduction motor 4 in sequence and extends in a direction away from the charging barrel 2. During implementation, the reduction motor 4 drives the plug rod 31 to rotate, so that the plug rod 31 moves along the axial direction of the reduction charging barrel 2, and then drives the plug head 32 to move along the axial direction of the charging barrel 2 to extrude the evenly mixed semi-finished material.

[0033] In this embodiment, the quantitative feeding assembly 6 is arranged at one end of the reduction motor 4 away from the charging barrel 2, and is used to control the moving distance of the piston assembly 3. In this way, it is convenient for the staff to do quantitative feeding. Specifically, the quantitative feeding assembly 6 includes a cylinder 61, a ruler 62, a relay 63 and a positioning rod 64. The cylinder 61 is covered on the outside of the plug rod 31, and the ruler 62 is fixed on one side of the cylinder 61. The length direction of the ruler 62 is parallel to the central axis of the cylinder 61, which is used to facilitate the staff to check the moving distance of the plug rod 31 assembly. The relay 63 is slidably arranged on the ruler 62. By setting the relay 63 to be slidably connected with the ruler 62, it is convenient to adjust the position of the relay 63 on the ruler 62. The positioning rod 64 is rotatably connected to the end of the plug rod 31 away from the plug head 32. The top of the cylinder 61 is provided with a clearance groove 611, and the top of the positioning rod 64 extends away from the cylinder 61 through the clearance groove 611.

[0034] It should be noted that the relay 63 of the present invention can adopt the Hall relay in the prior art. The top of the positioning rod 64 is provided with a magnet compatible with the Hall relay. The Hall relay is electrically connected to the reduction motor 4. When the positioning rod 64 moves to a position close to the Hall relay 63, the Hall relay sends a signal to stop the reduction motor 4 from working, thereby stopping the piston assembly 3 from moving.

[0035] For example, when loading materials, the staff can adjust the Hall relay 63 to the corresponding position according to the order quantity. For example: Assuming that the inner diameter of the loading barrel 2 is 5 cm, the loading thickness is 1 cm, and 100 meters of finished material (extruded strips) can be extruded through the extruder die, then if the order is to extrude 1000 meters of extruded strips, the material thickness needs to be adjusted to 10 cm. Therefore, when filling the material, the distance between the relay 63 and the positioning rod 64 needs to be adjusted to 10 cm (this distance is reflected on the ruler 62). After adjusting the distance, start filling the material, and then accurately add the material to avoid excessive material addition, which will cause waste of resources and increase costs, or less material addition will fail to meet the order requirements.

[0036] The connector assembly 5 is detachably connected to the open end 21 of the charging barrel 2, and the connector assembly 5 is used to be fixedly connected to an extruder die 9. The extruder die 9 is a prior art, including an extrusion port 91 of a specific shape, a heating mechanism 92 for heating and softening the material, and a thermocouple 93 for detecting the temperature in the die, etc., which will not be described in detail here. During implementation, the corresponding extruder die 9 can be selected according to customer needs to extrude the desired finished product shape.

[0037] It should be noted that the open end 21 of the charging barrel 2 is both a feed port and a discharge port. During implementation, the staff needs to disassemble the connector assembly 5 to put the mixed semi-finished material into the charging barrel 2, and then reinstall the connector assembly 5 and the extruder die 9. However, each disassembly of the connector takes a long time, which affects production efficiency. Therefore, the connector assembly 5 in the present invention is configured to facilitate disassembly of the clamping structure to improve work efficiency.

[0038] See also Figure 4 As shown, in this embodiment, a plurality of blocks 22 are convexly provided on the inner wall of the open end 21 of the charging barrel 2, and the plurality of blocks 22 are evenly arranged along the circumference of the charging barrel 2, and the gap between every two adjacent blocks 22 is defined as a clearance opening 23, and the connector assembly 5 includes a connector body 51 and a clamping portion 52, and the connector body 51 is used to be fixedly connected to the extruder die, and one end of the connector body 51 away from the extruder die is fixedly connected to the clamping portion 52. During implementation, the clamping portion 52 passes through the plurality of clearance openings 23 and is clamped with the plurality of blocks 22, thereby realizing a quick connection between the connector body 51 and the charging barrel 2.

[0039] Specifically, the clamping part 52 includes a plurality of connection blocks 521, which are respectively fixedly connected to one end of the connector body 51, and the plurality of connection blocks 521 are evenly arranged along the circumference of the connector body 51. At the same time, the plurality of connection blocks 521 correspond to the plurality of clearance openings 23 one by one, and one side of each connection block 521 is respectively provided with a receiving groove 5211 for receiving the clamping block 22. During implementation, the plurality of connection blocks 521 are inserted into the plurality of clearance openings 23, and then the connector assembly 5 is rotated so that the clamping block 22 is received in the receiving groove 5211, thereby realizing the quick connection between the connector assembly 5 and the charging barrel 2 through the clamping of the clamping block 22 and the connection block 521.

[0040] In this embodiment, a stopper block 522 is slidably connected between each two adjacent connecting blocks 521, and the sliding direction of the stopper block 522 is the same as the axial direction of the charging barrel 2. When the block 22 is accommodated in the accommodating groove 5211, the staff adjusts the stopper block 522 to slide in the direction close to the charging barrel 2. At this time, the stopper block 522 is located in the clearance opening 23, thereby preventing the clamping portion 52 from rotating in the opposite direction, thereby preventing the connector assembly 5 from separating from the charging barrel 2. The outer side of the clamping portion 52 is sleeved with a positioning ring 523 for driving the stopper block 522 to slide, and the positioning ring 523 is rotatably connected to the clamping portion 52. That is, through the positioning ring 523, it is convenient to drive multiple stopper blocks 522 to slide along the axial direction of the charging barrel 2.

[0041] Specifically, the positioning ring 523 is provided with a plurality of Z-shaped through slots 5231, and the plurality of through slots 5231 are evenly arranged along the circumference of the clamping portion 52, and each stop block 522 is fixed with a sliding rod 5221, and the plurality of sliding rods 5221 extend in the plurality of through slots 5231, and are slidably connected to the corresponding through slots 5231. Figure 3 As shown, the first end 52311 of the Z-shaped through groove 5231 is located in the direction close to the charging barrel 2, and the second end 52312 is located in the direction close to the connecting head body 51. When the positioning ring 523 is rotated counterclockwise, the sliding rod 5221 moves toward the first end 52311 close to the Z-shaped through groove 5231, thereby driving the stop block 522 to move toward the charging barrel 2. Conversely, when the positioning ring 523 is rotated clockwise, the sliding rod 5221 moves toward the second end 52312 close to the Z-shaped through groove 5231, thereby driving the stop block 522 to move toward the connecting head body 51. At this time, the stop block 522 disengages from the yielding port 23, and the staff rotates the clamping portion 52 in the opposite direction to separate the connecting block 521 from the stop block 522, thereby separating the connecting head assembly 5 from the charging barrel 2.

[0042] See also Figure 3 , Figure 4 Combined with Figure 5As shown, in this embodiment, a fixing ring 524 is sleeved on the outside of the positioning ring 523, and one end of the fixing ring 524 is fixedly connected to the connector body 51. In other words, the fixing ring 524 is sleeved on the outside of the clamping portion 52, and there is a receiving space between the fixing ring 524 and the clamping portion 52, and the positioning ring 523 is rotatably arranged in the receiving space, whereby the fixing ring 524 can protect the positioning ring 523 and improve the appearance. A straight notch 5241 is provided on the fixing ring 524 along the circumference of the fixing ring 524, and a threaded rod 5232 is fixed on the outer surface of the positioning ring 523, and the threaded rod 5232 passes through the straight notch 5241 and extends in a direction away from the positioning ring 523, and is screwed with a handle 525.

[0043] During implementation, after the connecting block 521 is engaged with the clamping block 22, the handle 525 is pulled to drive the positioning ring 523 to rotate, thereby causing the stop block 522 to slide in the direction close to the charging barrel 2 until the stop block 522 is engaged in the clearance opening 23. That is, by providing the handle 525, it is convenient for the staff to rotate the positioning ring 523. It should be noted that when the staff rotates the positioning ring 523 to the preset position, since the handle 525 and the threaded rod 5232 are screwed, the staff can rotate the handle 525 to move the handle 525 toward one end of the fixing ring 524 until one end of the handle 525 abuts against the fixing ring 524, thereby preventing the positioning ring 523 from rotating due to equipment vibration and other reasons, thereby increasing the stability of the clamping between the connector assembly 5 and the charging barrel 2. On the contrary, when the positioning ring 523 needs to be rotated, the handle 525 needs to be rotated first to move the handle 525 away from the fixing ring 524 , and at this time, the threaded rod 5232 can slide along the straight slot 5241 .

[0044] In this embodiment, the outer peripheral surface of the connector body 51 is connected with a plurality of injection ports 511, and the plurality of injection ports 511 are evenly arranged along the circumference of the connector body 51. A plug 512 is detachably connected to each injection port 511. When the injection port 511 is not needed, the corresponding injection port 511 can be blocked by the plug 512. When the corresponding injection port 511 is needed, the plug 512 can be disassembled. A discharge port 513 is provided at one end of the connector body 51 away from the clamping portion 52, and a discharge channel (not shown in the figure) is provided between each injection port 511 and the discharge port 513 for conveying materials to the extruder die 9 respectively.

[0045] In another embodiment of the present invention, a plurality of control cabinets 1 are included, such as Figure 6As shown (two are shown in the figure), each control cabinet 1 is fixedly provided with an extruder body, one end of the connecting head assembly 5 of one of the extruder bodies is fixedly provided with an extruder die 9, and one end of the connecting head assembly 5 of the remaining extruder bodies is respectively fixedly provided with connecting pipes 10, and the free ends of the multiple connecting pipes 10 are respectively connected to the multiple injection ports 511 of the connecting head assembly 5 that is fixed with the extruder die 9.

[0046] During implementation, the charging barrel 2 of each extruder body can be filled with materials of different materials, and the materials are collected in the connector body 51 connected to the extruder die 9 through the connecting pipes 10, so that the composite finished material can be extruded. Preferably, the bottom of the control cabinet 1 is rotatably connected with a plurality of rollers 11 to facilitate the movement of the control cabinet 1 and the extruder body, thereby making the equipment highly flexible, and adapting to the production of different types of materials (including single rubber strips and composite rubber strips) by adjusting the extruder die 9 and coordinating the movement of each control cabinet 1.

[0047] The above description is only a preferred embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
