Description

Technical Field

[0001] This utility model belongs to the technical field of coating machine equipment, and in particular relates to a preheating roller assembly for a coating machine. Background Technology

[0002] With the development of technology, the use of coating machines is becoming more and more widespread. This is because coating machines have advantages such as high degree of automation, simple operation, high production speed, uniform coating thickness, high adhesion, flat winding, environmental protection and no pollution, and saving labor and raw material costs. However, when using a coating machine, the preheating of materials requires the use of a preheating roller, which requires the use of a coating machine preheating roller assembly.

[0003] Chinese patent application CN218504997U discloses a preheating roller device for a coating machine, comprising: a base assembly placed on an outer contact surface for supporting internal components; a heating assembly including a rotating rod, a cylindrical shaft connected to the rotating rod, a first rotating shaft connected to the cylindrical shaft, a first turntable connected to the first rotating shaft, a first fixed shaft connected to the first turntable, a power cord connected to the first fixed shaft, a preheating roller connected to the first fixed shaft, a second fixed shaft connected to the other end of the preheating roller, a second turntable connected to the second fixed shaft, and a second rotating shaft connected to the second turntable; and a water cooling assembly for rapidly cooling the heated assembly after heating. By utilizing the function of the turntable device in conjunction with multiple sets of preheating rollers, the device allows for the direct use of new preheating rollers during operation by shaking the turntable, and unified maintenance and cleaning after work, thereby shortening the time for replacing preheating rollers during operation and improving work efficiency.

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. The above-mentioned preheating roller device for a coating machine, when the power cord is connected, the preheating roller starts to heat up. When it reaches a certain temperature, the operator starts working. However, the device cannot control the temperature of the preheating roller well, resulting in the film sticking to the preheating roller due to excessive temperature, which affects the quality of the film.

[0006] 2. The preheating roller device of the above-mentioned coating machine requires disassembly and cleaning after the film is applied to the preheating roller, which is cumbersome and reduces work efficiency.

[0007] To address these issues, we provide a preheating roller assembly for a coating machine. Utility Model Content

The surface of the preheating roller can be cleaned by the scraping component, avoiding the need to disassemble the preheating roller for cleaning, which reduces the efficiency of work. This solves the problem of inconvenient surface cleaning of the preheating roller assembly in existing coating machines.

[0009] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0010] This utility model relates to a preheating roller assembly for a coating machine, comprising a base, a fixing plate, a slag collection box, preheating rollers, and a controller. The fixing plate is symmetrically mounted on the upper side wall of the base, and the slag collection box is mounted on the upper side wall of the base. Two preheating rollers are positioned above the slag collection box. The controller is mounted on the upper side wall of the base. Rotating assemblies are mounted on the inner side walls of the preheating rollers, and two sealing assemblies are symmetrically mounted on the inner side walls of the preheating rollers. Scraping assemblies are mounted on the outer side walls of the preheating rollers. A coupling is mounted at the output end of the rotating motor of the rotating assembly. A rotating shaft is mounted on the left side wall of the coupling, and a heating tube is mounted on the outer side wall of the rotating shaft. A fixing block is mounted at the fixed end of the rotating shaft. A temperature sensor is positioned above the rotating shaft, and a fixing block is mounted on the lower side wall of the temperature sensor. An electric telescopic rod is mounted on the right side wall of the mounting plate of the sealing assembly, and a sealing plug is provided at the extended end of the electric telescopic rod. A connector is mounted at the extended end of the electric telescopic rod of the scraping assembly, and a mounting plate is mounted on the left side wall of the connector. A scraper is mounted on the left side wall of the mounting plate.

[0011] The present invention is further configured such that the left side wall of the fixed plate is detachably fixed to the support plate, the upper side wall of the support plate is connected to the rotary motor through the motor frame, and the input end of the rotary motor is connected to the output end of the controller.

[0012] The present invention is further configured such that the controller is connected to the temperature sensor via a wire, the temperature sensor is installed in the groove of the preheating roller, and the temperature sensor is connected to the preheating roller via a positioning block.

[0013] The present invention is further configured such that the inner wall of the preheating roller is detachably fixedly connected to the rotating shaft, the heat dissipation holes at both ends of the preheating roller are equipped with sealing plugs, the left side wall of the sealing plug is detachably fixedly connected to the connector, and the left side wall of the connector is detachably fixedly connected to the extended end of the electric telescopic rod.

[0014] The present invention is further configured such that the fixed end of the electric telescopic rod is detachably and fixedly connected to the mounting block, and the outer wall of the mounting block and the rotating shaft are detachably and fixedly connected.

[0015] The present invention is further configured such that the outer wall of the rotating shaft is detachably fixedly connected to the heating tube, and the input end of the heating tube is electrically connected to the output end of the controller.

[0016] The present invention is further configured such that two electric telescopic rods are installed vertically on the left side wall of the fixing plate, and the protruding ends of the two electric telescopic rods are detachably fixedly connected to the mounting plate through connectors. The electric telescopic rods are connected to the controller through wires.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model, by setting up a rotating component and a sealing component, controls the operation of the heating tube and temperature sensor on the controller. The heating tube heats the inside of the preheating roller, raising the internal temperature of the preheating roller and achieving the effect of preheating the material. At the same time, the temperature sensor constantly monitors the internal temperature of the preheating roller and feeds it back to the controller. When the temperature is too high, the heating tube stops working, and at the same time, the electric telescopic rod is controlled to drive the sealing plug to move, opening the heat dissipation holes at both ends of the preheating roller to achieve the effect of heat dissipation. This realizes the control of the internal temperature of the preheating roller, solving the problem that the temperature of the preheating roller cannot be well controlled, resulting in the film sticking to the preheating roller due to excessive temperature, which affects the quality of the film.

[0020] 2. This utility model, by setting up a scraping component, after the preheating roller has finished working, controls the movement of the electric telescopic rod on the controller. The electric telescopic rod pushes the connector and mounting plate to move on the surface of the two preheating rollers. During the movement of the mounting plate, it pushes the scraper to move on the surface of the preheating roller. The scraper cleans the film on the surface of the preheating roller and pushes the film into the slag collection box below for collection of residue, thus completing the cleaning of the surface of the preheating roller. This solves the problem that after the film adheres to the preheating roller, it is necessary to disassemble the preheating roller for cleaning, which is cumbersome and reduces work efficiency.

[0021] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Specific Implementation Example 1

[0032] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 This utility model is a preheating roller assembly for a coating machine, including a preheating roller 103 and two sealing components 3 symmetrically installed on the inner side wall of the preheating roller 103. The two sealing components 3 can control the sealing and heat dissipation effects of the preheating roller 103, thereby controlling the temperature change inside the preheating roller and solving the problem of inconvenient temperature control of the preheating roller 103 in the past.

[0033] Specifically, the right side wall of the mounting block 301 of the sealing component 3 is detachably fixed to the fixed end of the electric telescopic rod 401. The mounting block 301 facilitates the installation of the electric telescopic rod 401. At the same time, the mounting block 301 is detachably fixed to the outer side wall of the rotating shaft 203, so as to achieve the effect of synchronous movement between the mounting block 301 and the rotating shaft 203. This allows the electric telescopic rod 401 and the rotating shaft 203 to remain relatively stationary. The outer side wall of the rotating shaft 203 is detachably fixed to the preheating roller 103, which facilitates the rotation of the preheating roller 103. The outer side wall of the rotating shaft 203 is detachably fixed to the heating pipe 206, which fixes the heating pipe 206. The heating pipe 206 is located inside the preheating roller 103, which facilitates the heating of the preheating roller 103 by the heating pipe 206.

[0034] Furthermore, each of the heat dissipation holes 103a at both ends of the preheating roller 103 is equipped with a sealing plug 302. The heat dissipation holes 103a facilitate the heat dissipation of the preheating roller 103. The left side wall of the sealing plug 302 is detachably and fixedly connected to the electric telescopic rod 401 through the connector 402, realizing integration. The electric telescopic rod 401 can drive the sealing plug 302 to move synchronously. The input end of the heating tube 206 is electrically connected to the output end of the controller 104, so that the controller 104 can control the operation of the heating tube 206. The controller 104 is connected to the temperature sensor 205 through the wire. The temperature sensor 205 is installed in the groove of the preheating roller 103. The temperature sensor 205 is connected to the preheating roller 103 through the positioning block 205a, which fixes the temperature sensor 205 in the preheating roller 103 and constantly detects the temperature inside the preheating roller 103 and feeds it back to the controller 104.

[0035] The operation process of this embodiment is as follows: The controller 104 controls the heating tube 206 and the temperature sensor 205 to work. The heating tube 206 heats the inside of the preheating roller 103, raising the internal temperature of the preheating roller 103 and achieving the effect of preheating the material. At the same time, the temperature sensor 205 constantly detects the internal temperature of the preheating roller 103 and feeds it back to the controller 104. When the temperature is too high, the heating tube 206 stops working. At the same time, the electric telescopic rod 401 is controlled to drive the sealing plug 302 to move, opening the heat dissipation holes 103a at both ends of the preheating roller 103, achieving the effect of heat dissipation and realizing the control of the internal temperature of the preheating roller 103. Specific Implementation Example 2

[0037] Please see Figure 1 , Figure 2 and Figure 3 Based on the first specific embodiment, a scraping component 4 is installed on the outer wall of the preheating roller 103. The scraping component 4 facilitates the cleaning of the surface of the preheating roller 103, solving the problem of inconvenient surface cleaning of the existing preheating roller 103.

[0038] Specifically, the extended end of the electric telescopic rod 401 of the scraping component 4 is detachably and fixedly connected to the connector 402. The connector 402 serves as a connector, facilitating the connection of the electric telescopic rod 401 with other components. The extended ends of the electric telescopic rod 401 are all detachably and fixedly connected to the mounting plate 403 through the connector 402. The mounting plate 403 facilitates the installation of the scraper block 404. The left side wall of the mounting plate 403 is detachably and fixedly connected to the scraper block 404 to achieve integration. The electric telescopic rod 401 can drive the scraper block 404 to move synchronously.

[0039] Furthermore, two electric telescopic rods 401 are installed vertically on the left side wall of the fixed plate 101 to fix the electric telescopic rods 401. Both electric telescopic rods 401 are connected to the controller 104 through wires, so that the controller 104 can control the movement of the electric telescopic rods 401. The inner side wall of the mounting plate 403 is slidably connected to the outer side wall of the two preheating rollers 103, which facilitates the movement of the mounting plate 403 and the rotation of the preheating rollers 103. The outer side wall of the preheating rollers 103 is slidably connected to the scraper 404, which facilitates the movement of the scraper 404 to clean the surface of the preheating rollers 103.

[0040] The operation process of this embodiment is as follows: After the preheating roller 103 finishes working, the electric telescopic rod 401 is controlled to move on the controller 104. The electric telescopic rod 401 pushes the connector 402 and the mounting plate 403 to move on the surface of the two preheating rollers 103. During the movement of the mounting plate 403, the scraper 404 is pushed to move on the surface of the preheating roller 103. The scraper 404 cleans the film on the surface of the preheating roller 103 and pushes the film into the slag collection box 102 below to collect the residue and complete the cleaning of the surface of the preheating roller 103. Specific Implementation Example 3

[0042] Please see Figure 1 , Figure 2 and Figure 4 Based on specific embodiment one and specific embodiment two, a slag collection box 102 is provided below the preheating roller 103. The slag collection box 102 collects the residue cleaned off the preheating roller 103. A rotating component 2 is installed on the inner side wall of the preheating roller 103. The rotating component 2 can drive the preheating roller 103 to rotate.

[0043] Specifically, the output end of the rotary motor 201 of the rotating assembly 2 is connected to the rotating shaft 203 through the coupling 202. The coupling 202 serves as a connection and is connected to the fixed block 204 bearing at the fixed end of the rotating shaft 203 to facilitate the rotation of the rotating shaft 203.

[0044] Furthermore, a base 1 is installed on the lower side wall of the slag collection box 102. The base 1 facilitates the installation of the entire device. A fixing plate 101 is symmetrically installed on the upper side wall of the base 1. The fixing plate 101 provides support and facilitates the installation of the rotating component 2. The left side wall of the fixing plate 101 is detachably fixed to the support plate 207 to fix the support plate 207. The upper side wall of the support plate 207 is connected to the rotary motor 201 through the motor frame 201a. The motor frame 201a facilitates the installation of the rotary motor 201 and connects the input end of the rotary motor 201 to the output end of the controller 104, so that the controller 104 can control the operation of the rotary motor 201.

[0045] The operation process of this embodiment is as follows: the rotary motor 201 is started by the controller 104, and the rotary shaft 203 is driven to rotate under the action of the coupling 202. The rotary shaft 203 drives the preheating roller 103 to rotate, so that the preheating tube 103 can extrude and form the material.
