Description

Technical Field

[0001] The present application relates to the technical field of PE pipe processing, and specifically relates to a blanking and cutting device for PE pipes. Background Art

[0002] PE is polyethylene plastic, the most basic kind of plastic. Plastic bags, food wraps, etc. are all made of PE. PE has excellent properties in resisting most chemicals used in daily life and industry. PE pipes include medium-density polyethylene pipes and high-density polyethylene pipes.

[0003] The production process of PE pipes needs to go through the following procedures:

[0004] 1. Mixing and drying: The function of mixing and drying is to mix, dry, and blend the PE resin and the masterbatch to obtain a uniform raw material.

[0005] 2. Plasticizing and extruding: The raw material enters the extruder from the hopper. Through transportation, compression, melting, and homogenization, the solid granular material gradually becomes a highly elastic state, and then gradually becomes a viscous fluid (viscous flow state), and is continuously extruded.

[0006] 3. Die forming: At a suitable temperature, the material extruded from the extruder changes from rotational motion to linear motion through the filter plate and enters the die. After spiral separation, it is combined and compacted in the forming section into a tubular preform, and finally extruded from the die orifice.

[0007] 4. Cooling and shaping: The hot pipe preform extruded from the die is shaped and cooled in the sizing sleeve vacuum sizing box under negative pressure, and then passes through the spray cooling box to gradually cool the inside of the pipe, so as to be overall dried and shaped.

[0008] 5. Cutting: The PE pipe is cut into pipes of different or the same lengths according to the usage requirements.

[0009] In the prior art, during the cutting process of PE pipes, the feeding device continuously pushes the PE pipe to the cutting device. Subsequently, the cutting device clamps the PE pipe using a pre-positioning device and then cuts it. After cutting, the operator needs to manually remove and sort the materials, which is extremely inconvenient and time-consuming. Utility Model Content

[0026] Specifically, please refer to Figures 1 to 3 , Figure 1 which is the overall front view structural schematic diagram of the blanking and cutting device applied to PE pipes provided by the embodiment of the present application, Figure 2 and which is the side sectional view structural schematic diagram of the clamping device provided by the embodiment of the present application, Figure 3This is a schematic side cross-sectional structure diagram at the connecting rod provided by an embodiment of the present application. The blanking and cutting device 100 for PE pipes includes a first support platform 110, a second support platform 120, and a third support platform 130 arranged in sequence. The tops of the first support platform 110, the second support platform 120, and the third support platform 130 are approximately at the same horizontal height. The bottoms of the first support platform 110 and the third support platform 130 are supported by a support frame 140. The support frame 140 is used to support the first support platform 110 and the third support platform 130, and its structure and material can be selected according to actual situations. A conveying device 150 is supported on the support frame 140. The conveying device 150 is located below the first support platform 110, the second support platform 120, and the third support platform 130. The conveying device 150 can be a belt conveyor, etc., and it is used to convey the PE pipes that have been cut and fallen onto it to the outer end of the device. One end of the second support platform 120 is hinged to the end of the first support platform 110, so that the second support platform 120 can rotate around the hinge end, facilitating the conveyance of the cut PE pipes onto the bottom conveying device 150. A strip-shaped hole 131 is opened at one end of the third support platform 130 close to the second support platform 120. A first telescopic rod 132 is arranged in the strip-shaped hole 131. The free end of the first telescopic rod 132 is connected to a stop head 133. The stop head 133 extends to the outside of the strip-shaped hole 131. Driven by the first telescopic rod 132, the stop head 133 can move in the strip-shaped hole 131. When the first telescopic rod 132 extends, a part of the stop head 133 will protrude to the outside of the strip-shaped hole 131. When the first telescopic rod 132 retracts, the stop head 133 will retract into the strip-shaped hole 131. A lapping end 121 matching the stop head 133 is arranged at one end of the second support platform 120 close to the third support platform 130. When a part of the stop head 133 extends to the outside of the strip-shaped hole 131, the lapping end 121 can lap on the stop head 133. At this time, the stop head 133 will support the lapping end 121. At this time, both ends of the second support platform 120 will be stably supported on the first support platform 110 and the second support platform 120, facilitating subsequent cutting and other operations. A pre-limiting device 111 and a cutting device 112 are arranged on the first support platform 110. The pre-limiting device 111 is used to limit the PE pipes, and the cutting device 112 is used to cut the PE pipes. The pre-limiting device 111 and the cutting device 112 are both prior arts and have been fully disclosed and are well-known to those skilled in the art. Therefore, no further elaboration will be made here. A clamping device 160 is arranged on the top of the second support platform 120. The clamping device 160 is used to clamp the free end of the PE pipe, facilitating the cutting device 112 to cut the PE pipe. One side of the support frame 140 is hinged with a second telescopic rod 122. One end of the second telescopic rod 122 is hinged to the middle of the bottom side of the second support platform 120. The second telescopic rod 122 is used to drive the second support platform 120 to rotate around the hinge point between the second support platform 120 and the first support platform 110.

[0027] In the embodiment of the present application, during the working process, when the PE pipe is conveyed to the top of the first support table 110 by an external device, it will pass through the pre-limiting device 111. The PE pipe continues to move forward to the clamping device 160 at the top of the second support table 120 and can be clamped by the clamping device 160. At this time, the cutting device 112 cuts the PE pipe. After the cutting is completed, the first telescopic rod 132 retracts, and the stopper 133 enters the strip-shaped hole 131. Then the second telescopic rod 122 retracts, and the second support plate rotates around its hinge point. The cut PE pipe rotates together with it. Subsequently, the clamping device 160 is loosened, and the PE pipe slides down to the conveying device under the action of gravity and is conveyed to the packaging link by the conveying device. Subsequently, after the second telescopic rod 122 extends, it drives the second support table 120 to rotate upward around its hinge point. The first telescopic rod 132 drives the stopper 133 to partially protrude outside the strip-shaped hole 131 to re-support the second support table 120, and so on in a cycle.

[0028] As can be seen from the above, in the embodiment of the present application, by separating the support table into the first support table 110, the second support table 120, and the third support table 130, the support table of the present device can operate more flexibly, thereby facilitating the completion of multiple operations. By setting the second telescopic rod 122, the second support table 120 can be driven to rotate, so that the PE pipe completed with cutting at the top of the second support table 120 can slide onto the lower conveying device 150. This process has a high degree of automation and does not require manual operation by an operator, thus greatly reducing the labor cost and avoiding potential safety hazards during manual operation. On the other hand, in the present application, by setting the first telescopic rod 132, the stopper 133, and the strip-shaped hole 131, during the process of the first telescopic rod 132 driving the stopper 133 to move, the stopper 133 can support the free end of the second support table 120, thereby ensuring the stability of the second support table 120 during the processing.

[0029] In some embodiments, the clamping device 160 includes a fixed block 161 connected to the top of the second support table 120. The top of the fixed block 161 is connected with an inverted U-shaped fixing member 162. An arc-shaped groove 161a is formed at the top of the fixed block 161. The bottom of the fixing member 162 is connected with an arc-shaped clamping plate 164 corresponding to the arc-shaped groove 161a through a plurality of third telescopic rods 163. The embodiment of the present application provides a specific setting manner of the clamping device 160. By driving the arc-shaped clamping plate to rise or lower through the third telescopic rod 163, operations such as clamping or loosening the PE pipe can be realized.

[0030] In some embodiments, soft pads 165 are provided on the inner side of the arc-shaped clamping plate and the inner bottom wall of the arc-shaped groove 161a. In the embodiment of the present application, through the above settings, the stability and tightness during clamping can be higher.

[0031] In some embodiments, it includes a jet gun 170. The jet gun 170 is fixed to one side of the support frame 140. The air outlet end of the jet gun 170 is arranged to be inclined upward. The jet gun 170 is communicated with a gas supply device through a pipeline. In the embodiments of the present application, by setting the jet gun 170, when the second support platform 120 rotates downward and inclines for blanking, the jet gun 170 can jet air upward, so as to blow off impurities such as waste residues on the top of the second support platform 120, avoiding adverse effects on the subsequent operation of this equipment.

[0032] In some embodiments, it includes a connecting rod 180. The connecting rod 180 is arranged on the top of the second support platform 120 and on the side of the clamping device 160 close to the first support platform 110. An arc-shaped bent plate 181 is arranged at the top of the connecting rod 180. In the embodiments of the present application, through the above setting, the middle section of the PE pipe can be supported, avoiding the situation that the PE pipe cannot smoothly enter the inside of the clamping device 160 after being bent and deformed.

[0033] In some embodiments, a fixing platform 134 is arranged on the top of the third support platform 130. A touch switch 135 is arranged on the side of the fixing platform 134 close to the first support platform 110. The touch switch 135 is electrically connected to an alarm. In the embodiments of the present application, through the above setting, when the length measurement module of the equipment fails and the PE pipe extends too much, the free end of the PE pipe will squeeze the touch switch 135, and at this time the touch switch 135 will give an alarm.

[0034] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be covered within the scope of the claims and the description of the present application. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way.
