[0033] like Figure 1 As shown, the communication antenna is described in detail:

[0034] A communication antenna comprises a base 101, a central antenna 102 and a helical antenna 103. The central antenna 102 is fixed on the base 101, one end of the helical antenna 103 is fixed on the base 101, and the central antenna 102 is located at the center of the helical antenna 103.

[0035] The lower end surface of the base 101 is provided with magnetic material, so that the base 101 can be stably installed on the car. When used for communication, the stability of the car antenna signal is improved through the cooperation of the normal center antenna 102 and the helical antenna 103.

[0036] like Figure 2-10 As shown, an embodiment of processing the helical antenna 103 by the communication antenna processing equipment is described in detail:

[0037] A communication antenna processing equipment is used to process a helical antenna 103, including a support plate 202, a power wheel 301, a processing roller 302, a spiral groove 303, a square rod 304, a slide 401, a rolling rod 402 and a spring I 403; the support plate 202 is vertically arranged, the power wheel 301 rotates on the support plate 202, the square rod 304 is coaxially fixed on the power wheel 301, the processing roller 302 is slidably connected to the square rod 304, the processing roller 302 is provided with a spiral groove 303, a slide 401 slides on the support plate 202 above the power wheel 301, a rolling rod 402 rotates on the slide 401, and a spring I 403 is provided between the slide 401 and the support plate 202 to press the rolling rod 402 downward onto the processing roller 302.

[0038] During processing, the free end of the rolled raw material plate is placed in the spiral groove 303, and the raw material plate is pressed against the spiral groove 303 by the rolling rod 402. At this time, the first motor installed on the support plate 202 is started to transmit the power wheel 301, so that the power wheel 301 drives the processing roller 302 to rotate through the square rod 304, thereby driving the spiral groove 303 to rotate. At this time, the processing personnel press the raw material plate by hand to ensure that the raw material plate can be automatically fed as the spiral groove 303 rotates, thereby obtaining a spiral plate with the same pitch as the spiral groove 303;

[0039] The rolling rod 402 presses the raw material plate into the spiral groove 303 by the elastic force of the spring I 403. When the raw material plate rotates into the spiral groove 303 along with the spiral groove 303, the rolling rod 402 presses the raw material plate at two places, so that the friction between the spiral plate and the spiral groove 303 is sufficient for the spiral groove 303 to drive the raw material plate to feed automatically. Thus, the processing equipment can automatically process the spiral plate continuously without the assistance of the processing personnel, thereby improving the efficiency of processing the spiral plate.

[0040] Since the length of the processing roller 302 is limited and the spiral groove 303 thereon is limited, when the length of the spiral plate to be processed is greater than the length of the spiral groove 303, the first motor can be reversely started to drive the processing roller 302 to rotate in the opposite direction. At this time, since the processed spiral plate cannot retreat, the spiral plate will slide in the spiral groove 303. Then, when the spiral plate remains stationary, as the spiral groove 303 and the spiral plate that have been processed are spirally matched, the spiral plate will move relatively on the processing roller 302, so that the first processed spiral plate is separated from the spiral groove 303, and then the spiral groove 303 is again empty, so as to facilitate the continuous processing of the spiral plate again.

[0041] Moreover, through the sliding connection between the processing roller 302 and the square rod 304, when it is necessary to process spiral plates with different pitches or radii, the processing roller 302 can be replaced by a processing roller 302 with a spiral groove 303 that meets the requirements and installed on the square rod 304; thereby, this processing equipment can process raw material plates of different widths or thicknesses into a spiral shape, and can also process cylindrical spiral plates of different diameters.

[0042] Further:

[0043] By fixing the bottom plate 201 at the lower end of the support plate 202, support for the entire processing equipment is formed, ensuring that the support plate 202 is in a vertical state.

[0044] like Figure 2-10 As shown:

[0045] It also includes a vertical plate 503 fixed with a mounting shaft 505, the mounting shaft 505 is used to mount the raw material plate roll, the mounting shaft 505 is threadedly connected to the end away from the vertical plate 503 with a threaded sleeve 507, and the raw material plate roll is limited on the mounting shaft 505 between the vertical plate 503 and the threaded sleeve 507 through the threaded sleeve 507.

[0046] Further:

[0047] Buffer springs 506 are provided between the threaded sleeve 507 and the vertical plate 503 on both sides of the raw material coil.

[0048] By providing two buffer springs 506 , when installing the raw material roll, the two buffer springs 506 can elastically tighten both sides of the raw material roll to prevent axial movement of the raw material roll and adapt to raw material rolls of different widths.

[0049] like Figure 2-10 As shown:

[0050] A worm gear shaft 501 is fixed to the lower end of the vertical plate 503 . The worm gear shaft 501 rotates on the bottom plate 201 . A worm 502 rotates on the bottom plate 201 . The worm 502 is meshed and transmission-connected with the worm gear shaft 501 .

[0051] The installation of the vertical plate 503 and the bottom plate 201 is formed by the worm gear shaft 501. At the same time, in order to ensure that the plane direction of the raw material plate roll on the installation shaft 505 corresponds to the helix angle of the spiral groove 303 and remains stationary, a worm 502 is set. Through the self-locking function of the worm 502 and the worm gear shaft 501, the helix angle of the raw material plate roll and the spiral groove 303 correspond and remain stationary, and the raw material plate roll is driven to rotate by rotating the worm 502 to engage the transmission worm gear shaft 501 to adapt to the processing of different helix angles.

[0052] like Figure 2-10 As shown:

[0053] An auxiliary vertical plate 504 is extended from the vertical plate 503 near the processing roller 302 side, and a vertical sliding hole 508 is provided on the auxiliary vertical plate 504. An upper slide seat 601 and a lower slide seat 701 slide in the vertical sliding hole 508. A top wheel 603 rotates on the upper slide seat 601, and a pressure wheel 702 rotates on the lower slide seat 701. A spring II 703 is provided between the lower slide seat 701 and the auxiliary vertical plate 504 to make the pressure wheel 702 press the top wheel 603 downward. An adjusting sleeve 602 rotates at the lower end of the auxiliary vertical plate 504, and a screw on the lower slide seat 701 is threadedly connected to the adjusting sleeve 602.

[0054] The top wheel 603 is fixed with an edge 604 near the end of the auxiliary vertical plate 504, and a threaded support rod 607 is fixed to the other end of the top wheel 603. A ring plate 605 is slidably mounted on the top wheel 603, and a slide 606 is slidably mounted on the threaded support rod 607. The slide 606 is fixedly connected to the ring plate 605. A spring III 609 is provided between the slide 606 and the top wheel 603, and a nut 608 is threadedly connected to the threaded support rod 607.

[0055] Through the elastic force of spring II 703, the pressing wheel 702 presses the raw material plate against the top wheel 603, forming an auxiliary support for the raw material plate between the raw material plate roll and the spiral plate. At the same time, the two sides of the raw material plate are limited by the two edges 604 and the ring plate 605, so as to form a limit for the raw material plate before entering the spiral groove 303, ensuring that the raw material plate can enter the spiral groove 303, and when the processing roller 302 rotates for processing, the raw material plate remains stationary, and the processing roller 302 slowly slides on the square rod 304 as the processing proceeds. At the same time, through this limit, when the processing roller 302 rotates in the opposite direction, the processing roller 302 can slide back to the original position in the opposite direction, and continuous processing can be performed again;

[0056] By rotating the adjusting sleeve 602, the threaded transmission screw can drive the lower slide 701 to slide up and down, thereby adjusting the height of the raw material plate between the pressure wheel 702 and the top wheel 603 to adapt to the processing of processing rollers 302 of different diameters. By rotating the nut 608, the position of the nut 608 on the threaded support rod 607 is adjusted, and the spring III 609 is used to elastically tighten the slide 606, so that the slide 606 can drive the ring plate 605 to slide on the top wheel 603, thereby adjusting the distance between the ring plate 605 and the edge 604 to adapt to the spiral processing of raw material plates of different widths.

[0057] like Figure 2-10 As shown:

[0058] The end of the square rod 304 away from the power wheel 301 is fixed with a baffle 305 through a bolt 306, and a spring IV 307 is provided between the baffle 305 and the processing roller 302.

[0059] By setting the spring IV 307, when the processing roller 302 moves for processing, the friction between the spiral groove 303 and the spiral plate can be further increased by the elastic force of the spring IV 307, thereby ensuring the automatic processing.
