Description

Technical Field

[0001] This utility model relates to the technical field of idler roller decomposition equipment, and in particular to an ultra-high molecular weight polyethylene idler roller separation machine tool. Background Technology

[0002] Idler rollers typically consist of a steel liner and an outer cylinder. High-quality idler roller cylinders often use ultra-high molecular weight polyethylene (UHMWPE) as the material, a type of polyethylene with a molecular weight exceeding 1.5 million. UHMWPE has a heat distortion temperature of 85°C (at 0.46 MPa) and a melting point range of 130 to 136°C. It is a linear thermoplastic engineering plastic with excellent overall performance.

[0003] This material is renowned for its excellent wear resistance and self-lubricating properties, while also possessing high strength, stable chemical properties, and strong anti-aging capabilities. However, even with these superior characteristics, idler rollers will still experience wear after prolonged use, necessitating replacement. Used idler rollers, on the other hand, are worth proper disposal due to the recycling value of their components.

[0004] To achieve efficient resource utilization, a crucial step in the recycling process is separating the cylinder from the steel liner. Currently, this separation process mainly relies on manual operation, which is not only time-consuming and labor-intensive but also inefficient, failing to meet the demands of high-efficiency production. Therefore, improving existing separation technology to enhance operational efficiency has become an urgent issue to address. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model discloses an ultra-high molecular weight polyethylene idler roller separator.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] A machine tool for separating ultra-high molecular weight polyethylene idler rollers includes a frame, mounting bases, and an annular cutter head; mounting bases are provided at both ends of the top of the frame, one mounting base is equipped with the annular cutter head, and the other mounting base is equipped with a telescopic cylinder for pushing the idler roller through the annular cutter head; the annular cutter head is provided with multiple cutter heads for cutting the roller body at intervals along the circumferential direction.

[0008] Preferably, the top of the frame is provided with a roller support device for horizontally supporting the roller at a position corresponding to the position between the two mounting seats.

[0009] Preferably, the idler roller support device includes two brackets that are fastened to the frame, and support rods are provided at the bottom and on the left and right sides of the brackets.

[0010] Preferably, the support rod has a threaded rod that can move through the bracket, and the threaded rod has nuts threadedly connected to both the inner and outer sides of the bracket.

[0011] Preferably, the annular cutter head is fastened to a cutter holder, the cutter holder has an opening that allows the cutter head to move through, and a positioning screw for positioning the cutter head is threaded to one side of the cutter holder.

[0012] Preferably, the telescopic rod of the telescopic cylinder is detachably connected to a press-fit head.

[0013] By adopting the technical solution described above, this utility model has the following beneficial effects:

[0014] This utility model discloses an ultra-high molecular weight polyethylene idler roller separator, which has a simple structure, is easy to assemble, and has a low production cost. By pushing the idler roller with a telescopic cylinder, the idler roller passes through the central hole of the annular cutter disc, which can effectively reduce the labor intensity of the operator. During the process of the idler roller passing through the annular cutter disc, the cutter head cuts the cylinder body of the idler roller. During the cutting, the cutter tip is 1-2mm away from the steel liner to avoid scratching the steel liner. After cutting, only force needs to be applied to the cutting edge of the cylinder body to break the cylinder body at the cutting edge, thereby separating the cylinder body and the steel liner. The cylinder body can be recycled, while the steel liner can be directly reused.

[0015] This invention further provides a roller support device for horizontally supporting the roller at the position between the two mounting seats on the top of the frame. By supporting the roller with the roller support device, the safety factor of the cutting operation can be improved.

[0016] This invention further enables the support rod and bracket to be connected in an adjustable manner; it also enables the cutter head to be connected to the annular cutter disc via the cutter holder, and the cutter head and cutter holder are connected in an adjustable manner, which can be used to cut rollers of different diameters, making it highly practical.

[0021] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0022] Example 1, in conjunction with Appendix Figures 1-2 A high-molecular-weight polyethylene (UHMWPE) idler roller separator includes a frame 1, mounting bases 2, and an annular cutter head 4. Mounting bases 2 are located at both ends of the top of the frame 1. One mounting base 2 is equipped with the annular cutter head 4, and the other mounting base 2 is equipped with a telescopic cylinder 5 for pushing the idler roller through the annular cutter head 4. The telescopic cylinder 5 can be a hydraulic telescopic cylinder, a pneumatic cylinder, or an electric telescopic cylinder. The annular cutter head 4 has multiple cutter heads 6 spaced along its circumference for cutting the idler roller cylinder.

[0023] To ensure that the rollers are subjected to uniform force during the cutting operation and to avoid cutting failure due to bias to one side, the multiple cutter heads 6 should preferably be evenly distributed or symmetrically arranged.

[0024] In use, first control the telescopic cylinder 5 to shorten the telescopic rod, the operator aligns one end of the idler roller with the annular cutter disc 4 to ensure that the idler roller and the annular cutter disc 4 are coaxial, and then starts the telescopic cylinder 5 to push the idler roller through the center hole of the annular cutter disc 4. During this process, the cutter head 6 cuts the cylinder of the idler roller.

[0025] It is important to note that since the idler roller consists of a steel liner and a tightly fitted cylinder, the cutting head 6 should not directly contact the steel liner during cutting to avoid scratching. Therefore, the tip of the cutting head 6 should be kept 1-2 mm away from the steel liner during cutting. This way, after cutting, only appropriate force needs to be applied at the cutting point of the cylinder to break it apart, achieving separation of the cylinder and the steel liner. The cylinder can be recycled, while the steel liner can be directly reused.

[0026] Example 2: In actual use, it was found that it is dangerous for operators to hold the idler roller during operation, which can easily lead to safety accidents. In addition, there are many specifications of idler rollers on the market, and the diameter of idler rollers of different specifications is different. The fixed cutter head 6 cannot adapt to idler rollers of different specifications. In order to solve this technical defect, this example makes further improvements.

[0027] Combined with appendix Figure 1 and 3A type of ultra-high molecular weight polyethylene roller separator differs from Embodiment 1 in that, based on Embodiment 1, the top of the frame 1 is provided with a roller support device 3 for horizontally supporting the roller at the position between the two mounting seats 2. That is, the roller is supported by the roller support device 3. After the roller is placed on the roller support device 3, the roller automatically keeps coaxial with the annular cutter head 4, and then the telescopic cylinder 5 is activated. The telescopic cylinder 5 pushes the roller, so that the cylinder and the cutter head 6 move relative to each other, thereby achieving the purpose of cutting the cylinder.

[0028] Furthermore, the idler roller support device 3 includes two brackets 3-1 that are correspondingly and fastened to the frame 1. The bottom and left and right sides of the bracket 3-1 are provided with support rods 3-2, that is, the bottom and left and right sides of the idler roller are supported by the three support rods 3-2 respectively. The structure is simple and the production cost is low. Moreover, the support rods 3-2 can be cylindrical, which reduces the friction between the cylinder of the idler roller and the support rods 3-2.

[0029] Furthermore, the support rod 3-2 is provided with a screw 3-3 that movably passes through the bracket 3-1. The screw 3-3 is threaded with nuts 3-4 on both the inner and outer sides of the bracket 3-1. This means that the position of the support rod 3-2 can be adjusted by adjusting the position of the nuts 3-4 to accommodate rollers of different diameters. Specifically, when cutting large-diameter rollers, the support rod 3-2 is adjusted outwards, and when cutting small-diameter rollers, the support rod 3-2 is adjusted inwards, so that rollers of different diameters can be coaxial with the annular cutter head 4.

[0030] To accommodate idlers of different diameters, the annular cutter disc 4 is fastened with a cutter holder 7. The cutter holder 7 has an opening that allows the cutter head 6 to move through, and a positioning screw 8 for positioning the cutter head 6 is threaded on one side of the cutter holder 7. That is, the feed rate of the cutter head 6 can be adjusted by loosening the positioning screw 8. When cutting large-diameter idlers, the support rod 3-2 is adjusted outward to adjust the cutter head 6, and when cutting small-diameter idlers, the support rod 3-2 is adjusted inward to adjust the cutter head 6. This ensures that the tip of the cutter head 6 is 1-2 mm away from the steel lining of the idler, thus ensuring the cutting effect while avoiding damage to the steel lining.

[0031] Example 3, in conjunction with the appendix Figure 1 A type of ultra-high molecular weight polyethylene idler roller separation machine tool, based on embodiment 1 or 2, wherein the telescopic rod of the telescopic cylinder 5 is detachably connected to a pressing head 9, the diameter of the pressing head 9 being larger than the diameter of the telescopic rod of the telescopic cylinder 5, which facilitates alignment with the end face of the idler roller; when cutting idler rollers of different diameters, pressing heads 9 of different diameters can be replaced to avoid interference between the pressing head 9 and the idler roller support device 3.

[0032] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents within this utility model.
