Description

Technical Field

[0001] This application relates to the technical field of PE pipe production and processing, and particularly relates to a clamping device applied to PE pipes. Background Art

[0002] PE is polyethylene plastic, which is one of the most basic plastics. Plastic bags, food wraps, etc. are all made of PE. PE has excellent properties against most chemicals used in life and industry. There are medium-density polyethylene pipes and high-density polyethylene pipes for PE pipes. When cutting or adhesively butt-jointing, due to the large flexibility and viscosity of PE pipes, when large-diameter PE pipes are cut or adhesively butt-jointed, most of the PE pipes are fixed to a fixture and then a rotary cutting knife is used for cutting or melt butt-jointing. The clamping devices in the prior art all clamp and fix the PE pipes by means of driving an arc-shaped plate to extend by using a cylinder. Such a fixing method has the following problems: The size of each clamping device can only meet the clamping of PE pipes of one specification. When the size of the PE pipe changes, the corresponding-sized clamping plate needs to be replaced. Secondly, during the process of operating the clamping device to clamp, manual adjustment by the operator is required, and the operation is relatively cumbersome. Utility Model Content

[0003] In view of the above problems, the embodiments of this application provide a clamping device applied to PE pipes, which can facilitate the clamping operation of PE pipes of different sizes and liberate the hands of the operator so that they can perform other operations synchronously.

[0004] According to one aspect of the embodiments of this application, a clamping device applied to PE pipes is provided. The clamping device applied to PE pipes includes a horizontally arranged conveying frame. An operating component, a clamping component, and a conveying component are sequentially arranged on the top of the conveying frame. The operating component, the clamping component, and the conveying component are all coaxially arranged. The conveying component is used to drive the PE pipe to move along the horizontal direction of the conveying frame. The clamping component includes a positioning cylinder fixed on the top of the conveying frame. A strip-shaped hole is opened on one side of the positioning cylinder. An extrusion belt is fixedly connected to the inner side wall of the positioning cylinder. The other end of the extrusion belt passes through the positioning cylinder along the strip-shaped hole and is connected to a stepping component. A friction limiting component is arranged at the bottom of the positioning cylinder. The friction limiting component includes a jacking piece penetrating through the bottom of the positioning cylinder. A turning shaft is hinged to the bottom of the jacking piece. The middle part of the turning shaft is hinged to the conveying frame. The extrusion belt abuts against one end of the turning shaft away from the jacking piece.

[0005] In some embodiments, a roller component is hinged to one end of the turning shaft that abuts against the extrusion belt, and the extrusion belt is pressed on the outer side wall of the roller component.

[0006] In some embodiments, the jacking member includes a Y-shaped seat. Two positioning holes are formed in the positioning cylinder. Two wear pads that match the radian of the inner sidewall of the positioning cylinder are formed after the two ends of the top of the Y-shaped seat extend into the positioning cylinder along the two positioning holes respectively. The bottom of the Y-shaped seat is hinged to the turning shaft.

[0007] In some embodiments, abutting grooves are formed in the inner sidewall of the positioning cylinder on the outer periphery of the positioning holes. Abutting rings that match the two abutting grooves are sleeved on the two ends of the top of the Y-shaped seat respectively.

[0008] In some embodiments, a counterweight block is hung through a hinge at the bottom of the Y-shaped seat, and the counterweight block is suspended above the ground.

[0009] In some embodiments, a magnetic attraction expansion component is included. The magnetic attraction expansion component includes an electromagnet arranged at the top of the positioning cylinder. A magnetic component that matches the electromagnet is arranged on one side of the top of the extrusion belt.

[0010] The beneficial effects in this application are as follows: In this application, by setting up the positioning cylinder, the extrusion belt, and the friction limiting component to cooperate with each other. During the working process, after the operator steps on the stepping component downward, the jacking member on the friction limiting component will jack upward to the lower side of the PE pipe. Synchronously, the extrusion belt will press on the upper side of the PE pipe, and then the two will press the PE pipe from the upper and lower sides respectively. Thus, during the clamping operation of this application, it will not occupy the operator's hands, so that the operator's hands can simultaneously carry out relevant operations, thereby greatly improving the working efficiency of this application and reducing labor costs. On the other hand, since the extrusion belt is soft in texture, it can adapt to most PE pipes of different sizes, so that this device can operate on PE pipes with different diameters, further broadening the application scenarios of this device.

[0019] Specifically, please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the overall structure of the clamping device applied to PE pipes provided by the embodiments of the present application, Figure 2 This is a schematic cross-sectional structure diagram of the clamping component in the clamped state provided by the embodiments of the present application, Figure 3This is a schematic cross-sectional structure diagram of the clamping component in the relaxed state provided by the embodiments of the present application. The clamping device 100 for PE pipes includes a horizontally arranged conveying frame 110. The conveying frame 110 is used to fix structures such as an operating component 120, a clamping component 130, and a conveying component 140. Therefore, its structure and material can be set according to actual situations as long as the usage requirements are met, and will not be limited here. The operating component 120, the clamping component 130, and the conveying component 140 are sequentially arranged on the top of the conveying frame 110. The operating component 120, the clamping component 130, and the conveying component 140 are all coaxially arranged. The conveying component 140 is used to drive the PE pipe to move horizontally along the conveying frame 110. When the conveying component 140 drives the PE pipe to move horizontally to the coaxial operating component 120 and clamping component 130, the clamping component 130 can clamp the PE pipe, thereby restricting the movement of the PE pipe in the horizontal direction and its own circumferential direction, and then facilitating the operating component 120 to complete corresponding actions. It should be noted that the operating component 120 here can be a cutting component or a fusion bonding component, etc., according to different actual usage scenarios. The clamping component 130 includes a positioning cylinder 131 fixed on the top of the conveying frame 110. The positioning cylinder 131 is fixed above the conveying frame 110. The positioning cylinder 131 can be made of steel and can be connected to the positioning cylinder 131 by welding. During the operation, the PE pipe to be processed will pass through the positioning cylinder 131. A strip-shaped hole 131a is opened on one side of the positioning cylinder 131. An extrusion belt 132 is fixedly connected to the inner side wall of the positioning cylinder 131. The other end of the extrusion belt 132 passes through the strip-shaped hole 131a and extends out of the positioning cylinder 131 and is connected to a stepping component 132a. The stepping component 132a is used for the operator to insert their foot into. The stepping component 132a can be in the form of a hanging ring or an L-shaped hook. When the operator inserts their foot into the stepping component 132a and then presses down on the stepping component 132a, the stepping component 132a will drive the extrusion belt 132 to be tightened. Subsequently, the extrusion belt 132 will tightly press the PE pipe below it inside the positioning cylinder 131.A friction limiting component 133 is provided at the bottom of the positioning cylinder 131. The friction limiting component 133 includes a jacking member 133a passing through the bottom of the positioning cylinder 131. A turning shaft 133b is hinged to the bottom of the jacking member 133a. The middle of the turning shaft 133b is hinged to the conveying frame 110. The pressing belt 132 abuts against one end of the turning shaft 133b away from the jacking member 133a. When the stepping component 132a is pressed by an operator, synchronously, the pressing component will slightly move the turning shaft 133b downward. Further, after the turning shaft 133b rotates around the hinge point in the middle thereof, the end of the turning shaft 133b close to the jacking member 133a will be lifted upward. Subsequently, after the jacking member 133a is slightly lifted, it enters the inner cavity of the positioning cylinder 131 and supports on the bottom of the PE pipe, further increasing the friction force received by the PE pipe. At this time, under the dual action of the pressing belt 132 and the jacking member 133a, the PE pipe will be tightly clamped on the conveying frame 110.

[0020] As can be seen from the above, in the embodiment of the present application, by arranging the positioning cylinder 131, the pressing belt 132, the friction limiting component 133, etc. to cooperate with each other. During the working process, the operator only needs to press down the stepping component 132a, and the jacking member 133a on the friction limiting component 133 will jack upward to the lower side of the PE pipe. Synchronously, the pressing belt 132 will press on the upper side of the PE pipe, and then the two will press the PE pipe from the upper and lower sides respectively. Thus, during the clamping operation of the present application, it will not occupy the hands of the operator, and then the hands of the operator can simultaneously carry out related operation tasks, thereby greatly improving the working efficiency of the present application and reducing the labor cost. On the other hand, since the pressing belt 132 is soft in texture, it can adapt to most PE pipes of different sizes, and then the present device can operate on PE pipes with different diameters, further broadening the application scenarios of the present device.

[0021] In some embodiments, a roller component 133c is hinged to the end of the turning shaft 133b abutting against the pressing belt 132. The pressing belt 132 is pressed on the outer side wall of the roller component 133c. In the embodiment of the present application, through the above arrangement, the roller component 133c can convert the sliding friction part between the turning shaft 133b and the pressing belt 132 into rolling friction, thereby reducing the wear phenomenon of the pressing belt 132.

[0022] In some embodiments, the lifting member 133a includes a Y-shaped seat. Two positioning holes 131b are formed in the positioning cylinder 131. The two ends of the top of the Y-shaped seat respectively extend into the positioning cylinder 131 along the two positioning holes 131b, and two wear-resistant pads 133d that match the radian of the inner side wall of the positioning cylinder 131 are formed. The bottom of the Y-shaped seat is hinged to the turning shaft 133b. The embodiment of the present application provides a specific setting method for the lifting member 133a. Two wear-resistant pads 133d can be arranged above the Y-shaped seat, and the radian of the wear-resistant pads 133d and the radian of the inner side wall of the positioning cylinder 131 are both arc-shaped, so that after the lifting member 133a in the device is lifted, it can abut against the PE pipe with a larger area and more stably.

[0023] In some embodiments, an abutting groove 131c is formed on the inner side wall of the positioning cylinder 131 on the outer periphery of the positioning hole 131b. The two ends of the top of the Y-shaped seat are respectively sleeved with abutting rings 133e that match the two abutting grooves 131c. In the embodiment of the present application, through the above setting, when the operator stops pressing the stepping member 132a, the lifting member 133a will fall under its own gravity. When it falls to a suitable position, the abutting ring 133e will support on the inner bottom wall of the abutting groove 131c, thus avoiding the phenomenon that the lifting member 133a slides out of the positioning groove.

[0024] In some embodiments, a counterweight 150 is hung on the bottom of the Y-shaped seat through a hinge, and the counterweight 150 is suspended above the ground. In the embodiment of the present application, the weight of the counterweight 150 can be determined through experiments according to the actual situation. Under the action of the counterweight 150, when the operator stops pressing the stepping member 132a, the lifting member 133a will quickly fall and fall into the abutting groove 131c, thus avoiding the influence on the subsequent normal transportation of the PE pipe when the lifting member 133a continuously protrudes into the inner cavity of the positioning groove.

[0025] In some embodiments, a magnetic attraction expansion member 160 is included. The magnetic attraction expansion member 160 includes an electromagnet 161 arranged at the top of the positioning cylinder 131, and a magnet member 162 that matches the electromagnet 161 is arranged on one side of the top of the extrusion belt 132. In the embodiment of the present application, when one of the PE pipes is completed and needs to be replaced with another PE pipe for processing, the electromagnet 161 can be turned on. After the electromagnet 161 generates magnetism, it adsorbs the magnet member 162 on the top of the extrusion belt 132. Subsequently, the magnet member 162 drives the extrusion belt 132 to rise together and adhere to the inner side wall of the top of the positioning cylinder 131. The replaced PE pipe will not be blocked by the extrusion belt 132 and can be smoothly inserted into the positioning cylinder 131.

[0026] 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 it; 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 described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present application, and they should all be covered within the scope of the claims and the description of the present application.
