[0038] like Figure 1-11 As shown, the plastic pipe production device is described in detail:

[0039] A plastic pipe production device, characterized in that: it includes an inverted triangle box 101, a door frame 102 is fixed to the middle upper end of the box 101, the upper end of the box 101 has two support shafts 201 that rotate symmetrically, and support rollers 202 are fixed to the two support shafts 201, and side seats 207 are penetrated and slid on both sides of the lower end of the box 101, and tensioning shafts 203 are penetrated and rotated on the two side seats 207, and tensioning rollers 204 are fixed on the tensioning shaft 203, and support belts 205 are sleeved on the tensioning rollers 204 and the two support rollers 202, and the two support rollers 202 are provided with support belts 205. Springs I 208 are provided between the side seats 207 and the sides of the box body 101, so that the tensioning roller 204 moves downward to tension the support belt 205. Two slides 403 slide through the door frame 102, and a mounting plate 401 is fixed at the lower ends of the two slides 403. A long mounting hole 402 is provided in the middle of the mounting plate 401, and a plurality of drilling mechanisms are installed in the long mounting hole 402. Y-shaped frames 601 slide through both ends of the mounting plate 401, and a spring II 602 is provided between the Y-shaped frame 601 and the mounting plate 401.

[0040] First, the plastic pipe to be punched is axially placed on the support belt 205 between the two support rollers 202; at this time, the deadweight of the plastic pipe will press the support belt 205 downward, so that the support belt 205 of this section will bend and extend downward, and then pull the tensioning roller 204 to pull the two side seats 207 upward, so that the two side seats 207 squeeze the spring I 208, so that the support belt 205 is always kept in a tensioned state; and, as the support belt 205 between the two support rollers 202 bends downward, the plastic pipe will automatically keep parallel to the two support rollers 202 and be located between the two support rollers 202;

[0041] Then, by controlling the extension of the electric telescopic rod installed between the gantry 102 and the mounting plate 401, the mounting plate 401 will be pushed to drive the multiple punching mechanisms and the two Y-shaped frames 601 to descend; the two Y-shaped frames 601 will first contact the plastic tube, and the plastic tube will be pressed and fixed by the elastic force of the two springs II 602; wherein, since the lower end of the Y-shaped frame 601 is an open structure, the plastic tube can be clamped and pressed against the upper end of the plastic tube, and the plastic tube can be clamped and fixed in cooperation with the surrounding support of the support belt 205 at the lower end; and, since the two Y-shaped frames 601 are located at both ends of the mounting plate 401, the positions of the two Y-shaped frames 601 are beyond the end edge of the support belt 205, which will prevent the two Y-shaped frames 601 from contacting the support belt 205, thereby avoiding interference and affecting the fixation of the plastic tube;

[0042] As the mounting plate 401 continues to descend, the mounting plate 401 will squeeze the two springs II 602 to compress them, and then the multiple punching mechanisms will contact the upper side of the plastic tube at the same time and punch holes on the upper side of the plastic tube;

[0043] After the punching is completed, the mounting plate 401 is controlled to rise, so that the plastic pipe is rotated or axially moved, and the above operation is repeated again to complete the punching of the entire surface of the plastic pipe, thereby improving the punching efficiency.

[0044] When the plastic pipe is rotated, the motor installed on one of the side seats 207 can be controlled to start and transmit the tensioning shaft 203, thereby driving the support belt 205 to rotate, and then the friction between the plastic pipe and the support belt is used to rotate the plastic pipe; moreover, through the support of the support belt to the plastic pipe, the device can adapt to the support and fixation of plastic pipes of different diameters. When the diameter of the plastic pipe is larger than the width between the two support rollers 202, the support belt surrounds the lower end of the plastic pipe and mainly supports the plastic pipe through the two support rollers 202. When the diameter of the plastic pipe is smaller than the width between the two support rollers 202, the plastic pipe falls into the support belt between the two support rollers 202, and when it is pressed and fixed, the two side seats 207 slide to the uppermost end in the track hole on the side of the box body 101, thereby forming a support and fixation for the plastic pipe.

[0045] Further:

[0046] The inner side of the opening of the Y-shaped frame 601 is provided with anti-slip rubber.

[0047] The non-slip rubber contacts the plastic pipe, so the plastic pipe can be clamped and fixed more stably.

[0048] like Figure 4 As shown:

[0049] The outer surface of the support belt 205 is provided with a plurality of grooves 206 .

[0050] After multiple drilling mechanisms drill holes in the plastic pipe, a large amount of drilling chips will be generated. Since the upper end of the support belt 205 is concave, the drilling chips will fall on the support belt 205. When the plastic pipe is rotated or moved axially, these drilling chips will fall to the lower end of the plastic pipe and stay between the plastic pipe and the support belt 205, thereby affecting the flatness of the plastic pipe. Therefore, by providing multiple grooves 206 on the support belt 205, the drilling chips can be contained in the grooves 206, thereby ensuring that the outer surface of the support belt 205 supports the plastic pipe, reducing or even eliminating the influence of the drilling chips on the support of the plastic pipe.

[0051] like Fig.11 As shown:

[0052] The box body 101 moves relative to the support belt 205 and has two slide bars 702 that slide through the side. A scraper 701 is fixed inside the two slide bars 702. A spring III 703 is provided between the two slide bars 702 and the side of the box body 101 to make the scraper 701 press against the support belt 205.

[0053] Through the elastic force of spring III 703, the scraper 701 moves toward the support belt 205 and presses the support belt 205 tightly, so that when the support belt 205 moves, the scraper 701 can scrape the surface of the support belt 205 laterally, and then scrape off the drilling chips retained on the support belt 205.

[0054] Further:

[0055] The dropped drilling chips will be contained in the box 101 and slide down along the inner wall of the box 101 to the lower end, so that the discharge port 103 is provided at the lower end of the box 101, so as to facilitate the centralized collection and processing of the chips.

[0056] like Figure 4 and 6 As shown:

[0057] Auxiliary support shafts 301 are slidably mounted inside both ends of the two support shafts 201, and an auxiliary support roller 302 is fixed to the end of each auxiliary support shaft 301 away from the support shaft 201. A tensioning auxiliary shaft 303 is slidably mounted inside both ends of the tensioning shaft 203, and tensioning auxiliary rollers 304 are fixed to the ends of the two tensioning auxiliary shafts 303 away from the tensioning shaft 203. Auxiliary belts 305 are sleeved on the tensioning auxiliary rollers 304 and the two auxiliary support rollers 302 on the same side.

[0058] The two auxiliary support rollers 302 on the same side are rotatably provided with auxiliary plates 306 near the end of the box body 101 , and the two auxiliary plates 306 are rotatably provided with adjusting screws 307 , and the two adjusting screws 307 are respectively threadedly connected with the corresponding side surfaces of the box body 101 .

[0059] By setting two auxiliary support rollers 302 and a tension auxiliary roller 304, support is formed for the auxiliary belt 305, and the auxiliary belt 305 and the support belt 205 are at the same length, thereby forming auxiliary support for the plastic pipe, and preventing the plastic pipe from turning over when placing the plastic pipe;

[0060] Moreover, by rotating the adjusting screw 307, the auxiliary plate 306 can be driven to move axially, thereby adjusting the distance between the auxiliary belt 305 and the supporting belt 205, thereby improving the range and effect of the auxiliary support of the auxiliary belt 305.

[0061] Moreover, the auxiliary support shaft 301 is connected to the support shaft 201 by a key sliding connection, and the tensioning auxiliary shaft 303 is connected to the tensioning shaft 203 by a key sliding connection, thereby ensuring the synchronous rotation of the auxiliary belt 305 and the support belt 205.

[0062] like Figure 9-10 As shown:

[0063] The drilling mechanism includes a platform seat 501 with a drill bit seat 502 installed at the lower end, the platform seat 501 is provided with a boss 503 that cooperates with the mounting long hole 402, a limit pin 504 is provided at the center of the boss 503, a C-shaped plate 506 is slidably sleeved on the limit pin 504, and the C-shaped plate 506 can pass through the mounting long hole 402, and a plurality of pairs of limit grooves 404 are symmetrically provided on both sides of the upper end of the mounting long hole 402, and convex ridges 507 that cooperate with the limit grooves 404 are provided at both ends of the lower end surface of the C-shaped plate 506, and a spring IV 505 is provided between the C-shaped plate 506 and the limit pin 504, so that the C-shaped plate 506 presses the mounting plate 401 downward.

[0064] The drill seat 502 is used to install the drill bit, and a drilling motor is installed on the platform seat 501, which can drive the drill seat 502 to drive the drill bit to rotate, and then the drill bit can drill holes;

[0065] The elastic force of the spring IV 505 can push the C-shaped plate 506 downward to press against the mounting plate 401, and the two convex edges 507 at the lower end of the C-shaped plate 506 are respectively inserted into a pair of limiting grooves 404, so that the drilling mechanism is installed in the mounting long hole 402, and the limiting and fixing effect is achieved;

[0066] When the C-shaped plate 506 is pulled upward, the C-shaped plate 506 overcomes the elastic force of the spring IV 505 to drive the two convex edges 507 to slide out of the limiting groove 404, and the platform seat 501 can slide in the installation long hole 402 through the boss 503, thereby adjusting the position of the drilling mechanism, and then changing the relative positions and spacings of the multiple drilling mechanisms, so as to adapt to the plastic pipe drilling requirements of different needs;

[0067] Moreover, when the C-shaped plate 506 is pulled upward to make the two ridges 507 slide out of the limiting groove 404, the C-shaped plate 506 can be rotated so that the C-shaped plate 506 is rotated to be parallel to the mounting long hole 402, and the C-shaped plate 506 can be passed downward through the mounting long hole 402, so that the drilling mechanism can be removed from the mounting plate 401, so that the number of drilling mechanisms on the mounting plate 401 can be adjusted to facilitate the drilling of plastic pipes to meet different needs.

[0068] like Figure 1-11 As shown:

[0069] The production process using the plastic pipe production device comprises:

[0070] S1, placing the plastic pipe to be punched on the support belt 205 between two support rollers 202;

[0071] S2, controlling the mounting plate 401 to drive the multiple punching mechanisms and the two Y-shaped frames 601 to descend;

[0072] S3, the two Y-shaped frames 601 first contact the plastic tube and press and fix the plastic tube;

[0073] S4, as the mounting plate 401 continues to descend, multiple punching mechanisms punch holes on the upper side of the plastic pipe at the same time;

[0074] S5, after the control mounting plate 401 rises, the plastic tube is rotated or axially moved, and steps S2 to S4 are repeated again to complete the punching of the plastic tube.
