Description

Technical Field

[0001] The utility model relates to the technical field of EPE winding, in particular to a post-winding device for EPE. Background Technique

[0002] Polyethylene foamed cotton is a non-crosslinked closed-cell structure, also known as EPE pearl cotton, which is a new type of environmentally friendly packaging material. It is composed of countless independent bubbles generated by physical foaming of low-density polyethylene resin, overcoming the disadvantages of ordinary foamed rubber such as being fragile, deformed, and having poor recoverability. It has many advantages such as water-proof and moisture-proof, shock-proof, sound-insulating, heat-insulating, good plastic properties, strong toughness, recyclable, environmentally friendly, and strong impact resistance. It also has good chemical resistance and is an ideal substitute for traditional packaging materials. During the reproduction and processing of EPE coils, they need to be wound and then packaged and stored. After winding, the volume of the EPE decreases, which is convenient for transportation and placement, and can effectively ensure the hygiene of the EPE and facilitate the use of users.

[0003] In the existing winding machine during the winding process, the EPE is directly wound into a bundle, and there is no tightening operation on the EPE coil during the winding process. As a result, when the EPE coil is bundled, it is too loose, resulting in an overly large volume of the wound EPE, which is inconvenient for placement, and external substances are easily introduced into the interior of the EPE coil through the gaps, causing pollution to the EPE coil and being unfavorable for the use of the EPE.

The winding assembly includes a winding roller installed on the frame. A blanking roller is sleeved on the surface of the winding roller. An arc-shaped discharge port is opened on one side of the frame close to the blanking roller. An outlet rack located outside the frame is arranged below the discharge port. A driving mechanism is connected to the side of the winding roller away from the outlet rack.

[0006] Further, the driving mechanism is fixedly installed on the frame, and a baffle is arranged between the winding roller and the driving mechanism.

[0007] Furthermore, two groups of arc-shaped side baffles are symmetrically distributed on the side of the baffle close to the winding roller.

[0008] Furthermore, a circumferentially evenly distributed spline structure is arranged on the surface of the winding roller.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] An embodiment of the present utility model is asFigure 1 and Figure 2 As shown in Figure 2 , guide rollers 2 and a winding assembly 4 are respectively installed at both ends of a frame 1. At least one set of tension rollers 3 is arranged between the guide rollers 2 and the winding assembly 4. An adjusting cylinder is installed at the end of each tension roller 3 for adjusting the height of the tension roller to achieve the adjustment of dynamic tension force. The winding assembly 4 includes a winding roller 41 installed on the frame 1. A blanking roller 45 is sleeved on the surface of the winding roller 41. An arc-shaped discharge port is formed on one side of the frame 1 close to the blanking roller 45, which is convenient for installing the winding roller and avoiding interference. A discharge rack 5 located outside the frame 1 is arranged below the discharge port. After the EPE is wound up, the blanking roller with the EPE is removed through a blanking structure and placed on the discharge rack. The blanking structure can specifically adopt structures such as a manipulator, and the specific content is not the content protected by this application. A driving mechanism 44 is connected to the side of the winding roller 41 away from the discharge rack 5. Specifically, a driving motor can be adopted to provide power for the winding roller.

[0020] The driving mechanism 44 is fixedly installed on the frame 1. A baffle 42 is arranged between the winding roller 41 and the driving mechanism 44. The baffle provides limit and deviation correction for the EPE during the EPE winding operation, ensuring that the EPE is wound neatly.

[0021] Two groups of arc-shaped side baffles 43 are symmetrically distributed on the side of the baffle 42 close to the winding roller 41 for limiting the winding of the EPE. An optical detection switch or other sensor structures can be installed inside the arc-shaped side baffle for detection when the EPE is wound to a certain thickness, which is convenient for subsequent blanking.

[0022] A circumferentially evenly distributed spline structure 411 is arranged on the surface of the winding roller 41, which improves the connection stability and reliability and helps to improve the torque transmission efficiency. A conical locking groove 412 is arranged on the end face of the winding roller 41 on the side away from the baffle 42, and the depth of the locking groove 412 is less than the length of the winding roller 41.

[0023] Air holes 413 are formed between the spline structures 411 on the surface of the winding roller 41. The air holes 413 are connected to a pneumatic device 6 inside the frame 1. During the process of disassembling the blanking roller, gas is input into the air holes through the pneumatic device to form an air gap between the winding roller and the blanking roller, reducing the friction force and making it easier for the blanking roller to separate from the winding roller, thus improving the roll changing efficiency.

[0024] The blanking roller 45 is a hollow sleeve structure with a baffle on one side. The blanking roller 45 is connected to the winding roller 41 through splines. A positioning pin 46 is arranged outside the baffle of the blanking roller 45. The positioning pin fixes the blanking roller on the winding roller to ensure that the blanking roller and the winding roller can rotate synchronously. A threaded hole is opened in the center of the positioning pin for further fixation.

[0025] The positioning pin 46 corresponds to the locking groove 412 in structure. The positioning pin 46 has a conical structure. A rectangular pressing plate 461 is arranged on the outer side of the positioning pin 46. An anti-rotation block 462 that is clamped in the locking groove 412 is arranged on one side of the positioning pin 46 close to the pressing plate 461, providing a limiting function to prevent the positioning pin from sliding during fixation and ensuring the connection stability.

[0026] The following points need to be explained: First, in the description of this application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. It can be a mechanical connection or an electrical connection, or it can be the communication inside two components. It can be directly connected. The terms "upper", "lower", "left", "right", etc. are only used to represent the relative position relationship. When the absolute position of the object being described changes, the relative position relationship may change. Second, in this article, relational terms such as first and second are only used to distinguish one entity from another entity, and do not necessarily require or imply any such actual relationship or order between these entities.
