Description

Technical Field

[0001] This application relates to the field of heat-conducting roller technology, specifically a heat-conducting roller with uniform heat distribution. Background Technology

[0002] A heat-conducting roller is an industrial device used to transfer heat, commonly found in various production and processing fields. It consists of a roller, heating element, temperature control system, bearings, and journals. Heat-conducting rollers typically employ three heating methods: electric heating, thermal oil heating, and electromagnetic heating.

[0003] For example, patent CN208392875U discloses a heat-conducting roller with uniform heat distribution, including a roller, heating blocks, grooves, a collector ring, a roller shaft, and bearings. The heating blocks distribute heat evenly within the roller cavity, and the grooves between the heating blocks effectively prevent excessive heat concentration on the roller surface.

[0004] The aforementioned patented heat-conducting roller has several drawbacks during use. Because the roller shaft is located inside the roller, and the heating block is installed within the roller's inner cavity, the heating block may become damaged with prolonged use. Furthermore, due to the integrated installation structure of the roller and roller shaft, repairing or replacing the heating element inside the roller is inconvenient. Therefore, a heat-conducting roller with uniform heat distribution is needed to address these issues.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0006] Based on the aforementioned problems in the existing technology, the problem to be solved in this application is to provide a heat-conducting roller with uniform heat distribution, thereby addressing the issue in the aforementioned patent where, during the mixing of composite scraper adhesive materials, the complex composition of the composite scraper adhesive materials, including filler particles of different sizes (such as calcium carbonate, silicon dioxide, etc.), may gradually settle due to gravity. Secondly, if the composite scraper adhesive material has a high viscosity and poor flowability, it is also easy for some materials to accumulate at the bottom of the mixing tank, failing to mix thoroughly, thus leading to an imbalance in the proportions of the various components of the scraper adhesive.

[0007] The technical solution adopted by this application to solve its technical problem is: a heat-conducting roller with uniform heat distribution. It mainly includes: a roller with a hollow groove at one end; an end cap mounted on the roller, with a groove on the other side of the end cap containing six sets of heating rods; three sets of insert plates mounted on the end cap, with slots on the roller; a fixing ring sleeved on the roller, the fixing ring having a notch, with two sets of protruding blocks installed at the notch, and fastening bolts threaded onto the protruding blocks; a limiting ring installed on the inner wall of the fixing ring, the limiting ring having an opening corresponding to the notch, and a second step between the limiting ring and the inner wall of the fixing ring; and at least three sets of limiting mechanisms mounted on the end cap.

[0008] Furthermore, the insert plates are proportionally distributed on the side of the end cap.

[0009] Furthermore, the heating rods are proportionally distributed on the end cap.

[0010] Furthermore, the limiting mechanism includes a fixed seat mounted on the end cap, a handle hingedly mounted on the fixed seat, a limiting seat mounted on the handle, the limiting seat having a through hole, a straight rod movably passing through the through hole, a connecting rod hingedly mounted between the handle and the straight rod, a positioning pin mounted on one end of the limiting seat, and a positioning hole opened on the limiting ring.

[0011] Furthermore, a grip sleeve is installed on the grip.

[0012] The beneficial effects of this application are: the heat-conducting roller with uniform heat distribution provided by this application, through the setting of end cap, groove, heating rod, insert plate, fixing ring, fastening bolt, limiting ring, positioning hole limiting mechanism, so that when it is necessary to repair or replace the heating rod located inside the roller, the staff can relatively easily remove the fixing components and other related parts, and then smoothly access the location of the heating rod to carry out maintenance and disassembly work.

[0013] In addition to the purposes, features, and advantages described above, this application has other purposes, features, and advantages. A further detailed description of this application will be provided below with reference to the figures. Attached Figure Description

Detailed Implementation

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] like Figures 1-4 As shown, this application provides a heat-conducting roller with uniform heat distribution, including a roller 1, a first roller shaft 14 fixedly installed at one end of the roller 1, the first roller shaft 14 being suitable for connection with an external bearing to support the roller 1, and a hollow groove 11 being provided at one end of the roller 1, with a first step 12 between the hollow groove 11 and the opening at one end of the roller 1.

[0026] A fixing component 2 is installed at one end opening of the roller 1. The fixing component 2 includes an end cap 21 installed at one end opening of the roller 1. A second roller shaft (not shown in the figure) is fixedly installed on the side of the end cap 21. The second roller shaft is suitable for connection with an external bearing to support the roller 1.

[0027] A groove 22 is provided on the other side of the end cap 21, and six sets of heating rods 23 are fixedly installed in the groove 22. The heating rods 23 are distributed proportionally on the end cap 21 to achieve uniform heat distribution on the heat-conducting roller. Three sets of insert plates 24 are fixedly installed on the end cap 21. The insert plates 24 are distributed proportionally on the side of the end cap 21. At the same time, a slot 13 adapted to the insert plates 24 is provided at one end opening of the roller 1. The end cap 21 is suitable for the insert plates 24 to be inserted into the slot 13 to initially fix the end cap 21 to one end of the roller 1.

[0028] Furthermore, a retaining ring 25 is fitted onto the roller 1. The retaining ring 25 has a certain elasticity and a notch. Two sets of protruding blocks (not shown in the figure) are fixedly installed at the notch. Fastening bolts 26 are threaded onto the protruding blocks, and a nut is threaded onto one end of the fastening bolts 26. The retaining ring 25 is suitable for fastening by the fastening bolts 26.

[0029] A limiting ring 27 is fixedly installed on the inner wall of the fixing ring 25. The limiting ring 27 has an opening that corresponds to a notch. A second step 28 is provided between the limiting ring 27 and the inner wall of the fixing ring 25. The fixing ring 25 is clamped to the roller 1 by the limiting ring 27. At the same time, one end of the end cap 21 abuts against the second step 28 and is then fastened by the fastening bolt 26 to fix the roller 1 and the end cap 21.

[0030] With the above connection method, when it is necessary to repair or replace the heating rod 23 located inside the roller 1, the staff can relatively easily remove the fixing component 2 and other related parts, and then smoothly access the location of the heating rod 23 to carry out the repair and disassembly work.

[0031] To further explain, in order to prevent the end cover 21 from rotating when the first roller shaft 14 and the second roller shaft are rotated by an external driving device, the roller 1 is driven to rotate by the insertion plate 24 and the slot 13. Since the fixing ring 25 and the end cover 21 are only fastened by the fastening bolt 26, when the first roller shaft 14 and the second roller rotate at a high speed, relative displacement will occur, which will affect the normal conveying of materials.

[0032] like Figures 2-4As shown, three sets of limiting mechanisms are installed on the end cap 21. The limiting mechanism includes a fixed seat 210 fixedly installed on the end cap 21, and a handle 211 is hingedly installed on the fixed seat 210. At the same time, a limiting seat 212 is fixedly installed on the handle 211. The limiting seat 212 has a through hole (not shown in the figure), and a straight rod 214 is movably passed through the through hole. At the same time, a connecting rod 213 is hinged between the handle 211 and the straight rod 214. A positioning pin 215 is fixedly installed at one end of the limiting seat 212. At the same time, a positioning hole 29 adapted to the positioning pin 215 is opened on the limiting ring 27.

[0033] As the handle 211 rotates, the connecting rod 213 drives the straight rod 214 to move through the through hole in the limiting seat 212. Simultaneously, the positioning pin 215 also moves with the rotation of the handle 211. Ultimately, the positioning pin 215 penetrates the end cap 21 and accurately engages with the positioning hole 29. When the positioning pin 215 engages with the positioning hole 29, a stable connection is established between the end cap 21 and the limiting ring 27 (associated with the fixing ring 25), limiting any possible relative displacement between them. This ensures that even if the first roller shaft 14 and the second roller shaft rotate at high speeds during the operation of the heat-conducting roller, slippage and other displacements that previously occurred due to relying solely on the fastening bolts 26 can be avoided as much as possible, guaranteeing the stable operation of the entire device.

[0034] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
