Description

Technical Field

[0001] The utility model relates to the field of PE pipe processing and production, in particular to a PE pipe cutting machine blanking component. Background Art

[0002] The original PE pipes purchased by the production workshop are generally long pipes, and then the long PE pipes are cut into PE pipes of required length according to production needs. After the PE pipe cutting machine completes the cutting, when unloading from the conveyor belt or similar functional channels, the PE pipes are often unloaded vertically. The reason is that the width of the unloading channel is limited, and its width is often smaller than the length of the PE pipe after cutting.

[0003] Therefore, when the PE pipe is being fed vertically, the front end of the PE pipe is likely to hit the side baffle of the feeding channel, causing the PE pipe to get stuck. This will not only prevent the PE pipe from being fed smoothly, but will also affect the subsequent feeding of PE pipes. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a PE pipe cutting machine blanking assembly to solve the technical problem in the prior art that the front end of the PE pipe abuts against the side baffle plate during blanking and causes jamming.

[0005] Based on the above purpose, the utility model provides a PE pipe cutting machine blanking assembly, including a cutting device and a blanking assembly installed on the outlet side of the cutting device, the blanking assembly includes:

[0006] A material unloading inclined platform and protective side platforms installed on both sides of the material unloading inclined platform, wherein the protective side platforms are hollow box-shaped parts;

[0007] A movable plate movably connected to the protective side platform, wherein a plurality of telescopic driving parts are fixedly connected to the inner side of the movable plate, and the telescopic driving parts are pneumatic parts, and are used to drive the movable plate to telescope in a direction parallel to the unloading inclined platform;

[0008] The air supply pipe for supplying air to the telescopic drive part is connected with the air inlet pipe through the electromagnetic three-way valve, and the outer end of the air inlet pipe is connected to the air pump.

[0009] Furthermore, the telescopic drive unit is composed of a sleeve and a telescopic rod. The inner cavity of the sleeve is connected to the air pipe and is fixedly connected to the protective side platform. The outer end of the telescopic rod is fixedly connected to the inner side of the movable plate, and the inner end of the telescopic rod is slidably connected to the inner cavity of the sleeve.

[0010] Furthermore, a return spring is provided in the inner cavity of the sleeve, and two ends of the return spring are respectively connected to the bottom of the inner cavity of the sleeve and the inner end of the telescopic rod.

[0011] Furthermore, another port of the electromagnetic three-way valve is connected to a vent pipe, and the vent pipe is directly connected to the external atmosphere.

[0012] Furthermore, when the telescopic drive unit is in an initial state, the outer end surface of the movable plate is flush with the inner surface of the protective side platform, and the initial state of the telescopic drive unit is a state when the air pipe does not supply air to the telescopic drive unit.

[0013] Furthermore, the unloading ramp is connected to the cutting device via a unloading platform, and a plurality of rollers in contact with each other are provided on the unloading platform.

[0014] Furthermore, the upper and lower ends of the movable plate are provided with closing plates extending toward the inside of the protective side platform.

[0024] Specific implementation method and principle

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0026] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs. The words "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0027] The first aspect of the utility model is as follows Figure 1 and Figure 2 As shown, the material unloading assembly of the present solution is installed at the outlet side of the cutting device 101, and includes two parts: a material unloading platform 102 and a material unloading inclined platform 103, wherein a plurality of rollers in contact with each other are arranged on the material unloading platform 102. These rollers can be driven by an external power source, or can be driven by a power source and rotate freely. When the rollers are driven by a power source, workers need to manually push the PE pipe 01 down and onto the material unloading inclined platform 103 after the cutting machine has cut the PE pipe 01.

[0028] The key point is that the unloading ramp 103 of this solution is equipped with a protective side platform 104 to replace the original side baffle.

[0029] like Figure 2 , Figure 3 and Figure 4As shown, the protective side platform 104 is a hollow box-shaped part, and a movable plate 105 is arranged inside, wherein, in the initial state, the outer end surface of the movable plate 105 is flush with the inner side surface of the protective side platform 104. A plurality of telescopic drive parts are arranged at the inner end of the movable plate 105, and the telescopic drive parts are pneumatic parts. The simplest way is to use an airbag as the telescopic drive part, and the airbag is inflated to drive the movable plate 105 to extend, and then the airbag is contracted by pumping air, so that the movable plate 105 is retracted. When this method requires the air pump 110 to perform alternating blowing and pumping, especially when the movable plate 105 needs to be periodically extended and retracted, it is not friendly to the air pump 110, and this method requires a separate air pump 110 or even a separate air circuit, because the workshop air pump is often always blowing air to provide pneumatic force, and the workshop air circuit is always in a high-pressure state.

[0030] Therefore, preferably, Figure 5 As shown, a telescopic drive unit is composed of a sleeve 111, a telescopic rod 112 and a return spring 113. The inner cavity of the sleeve 111 is connected to the gas pipe 106 and is fixedly connected to the protective side platform 104. The outer end of the telescopic rod 112 is fixedly connected to the inner side of the movable plate 105, and the inner end of the telescopic rod 112 is slidably connected to the inner cavity of the sleeve 111. A return spring 113 is provided in the inner cavity of the sleeve 111, and the two ends of the return spring 113 are respectively connected to the bottom of the inner cavity of the sleeve 111 and the inner end of the telescopic rod 112.

[0031] The air supply pipe 106 supplies air to the telescopic drive part, and the air supply pipe 106 is connected to the air inlet pipe 108 through the electromagnetic three-way valve 107. The outer end of the air inlet pipe 108 is connected to the air pump 110. In addition, the other port of the electromagnetic three-way valve 107 is connected to the air release pipe 109, and the air release pipe 109 is directly connected to the external atmosphere.

[0032] Preferably, if the workshop has its own air circuit, the outer end of the air inlet pipe 108 can be directly connected to the workshop air circuit. If the workshop does not have an air circuit, an air pump 110 needs to be installed.

[0033] Therefore, the movable plate 105 is driven by blowing air to push the movable plate 105 out, and automatically retracts by spring contraction after the electromagnetic three-way valve 107 is deflated. The control is performed by the electromagnetic three-way valve 107, which is simple and fast.

[0034] The electromagnetic three-way valve 107 has only two states available for switching. One is that the air intake pipe 108 (and the air supply pipe 106) is connected and the air release pipe 109 is closed; the other is that the air intake pipe 108 is closed and the air release pipe 109 (and the air supply pipe 106) is connected.

[0035] On the other hand, in this solution, the movable plate 105 can be extended and retracted in two modes. One is automatic periodic extension and retraction, which does not require waiting until the PE pipe is stuck before reacting, and does not require real-time observation, whether manual observation or using sensing equipment. The other mode is that after the worker sees that the PE pipe is stuck, or after the sensing equipment senses that the PE pipe is stuck, the movable plate 105 is started to extend and retract by switching the state of the electromagnetic three-way valve 107.

[0036] When the movable plate 105 is extended, one thing needs to be noted. Since the protective side platform 104 is a hollow box-shaped member, the movable plate 105 will be extended to cause the upper and lower ends of the movable plate 105 and the protective side platform 104 to be exposed. Therefore, when PE01 is being unloaded, it is easy to insert into the gap between the movable plate 105 and the protective side platform 104. Therefore, the upper and lower ends of the movable plate 105 need to be provided with closing plates extending into the protective side platform 104. Ensure that after the movable plate 105 is extended, the space between the movable plate 105 and the protective side platform 104 is still closed. DETAILED DESCRIPTION

[0037] After the cutting machine cuts the PE pipe 01, the PE pipe 01 enters the unloading ramp 103 through the unloading platform 102. The movable plate 105 in the unloading ramp 103 can be extended and retracted in two modes. One is to periodically extend and retract by controlling the switching state of the electromagnetic three-way valve 107 to automatically switch the state. The other way is that after the worker sees that the PE pipe is stuck, or after the sensing device senses that the PE pipe is stuck, the movable plate 105 is started to extend and retract by switching the state of the electromagnetic three-way valve 107.

[0038] Before the movable plate 105 is extended, the electromagnetic three-way valve 107 is switched to the inlet pipe 108 (between the air supply pipe 106) and the air discharge pipe 109 is closed. The air supply pipe 106 blows air into the inner cavity of the sleeve 111, forcing the telescopic rod 112 to be extended. The telescopic rod 112 is extended under force, and the movable plate 105 is extended with it. Push the stuck PE pipe 01 back to the middle.

[0039] Then the electromagnetic three-way valve 107 switches to close the air inlet pipe 108, and the air release pipe 109 (between the air supply pipe 106) is connected. At this time, the gas in the inner cavity of the sleeve 111 is discharged through the air supply pipe 106, the electromagnetic three-way valve 107 and the air release pipe 109. The telescopic rod 112 retracts and returns to its original position under the action of the return spring 113, and the retraction of the telescopic rod 112 brings the movable plate 105 back, so that the PE pipe 01 can be unloaded smoothly.

[0040] Based on the above, the utility model sets an extendable movable plate 105 on the protective side platform 104 to push the stuck PE tube 01 back to the middle, and then the movable plate 105 quickly retracts, so that the PE tube 01 can be unloaded smoothly. The movable plate 105 is driven by air to push it out, and automatically retracts by spring contraction after deflation, which is simple to control and quick to respond.
