Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of CPE film heat sealers, specifically, to a CPE film heat sealer. Background Technology

[0002] In the production and quality inspection of CPE film, heat-sealing performance is a key indicator of its quality, making a heat-sealing instrument indispensable. A heat-sealing instrument is a device used to test the heat-sealing performance of materials such as plastic films and composite films. The following is a detailed introduction to heat-sealing instruments: A heat-sealing machine heats a heat-sealing blade or plate to a set temperature using a heating device, while simultaneously applying pressure and maintaining the temperature for a certain time. This allows the material to be sealed to achieve heat sealing under the combined action of heat and pressure. Its core principle is that when the material is heated to a certain temperature, molecular motion intensifies, polymer chain segments entangle and diffuse, and under pressure, they fuse together, forming a strong seal upon cooling. Currently, traditional CPE film heat-sealing testing often uses flat-plate hot-press testing, where the CPE film is placed between two heated plates, and the heat-sealing effect is tested by simulating the heat-sealing process through pressure and heat.

[0003] However, this traditional method has obvious drawbacks. On the one hand, in actual production, CPE film heat sealing is a dynamic and continuous process, while flat plate heat pressing is a static operation, which cannot reflect the performance changes of CPE film during dynamic heat sealing, resulting in deviations between test results and actual applications. On the other hand, the large contact area between the flat plate and the CPE film makes it difficult to transfer pressure and heat evenly, resulting in different heat sealing effects in different parts of the CPE film, affecting the accuracy of the test.

[0004] Therefore, it is essential to develop a CPE film heat sealer that utilizes a rolling method for hot-press testing. This new type of heat sealer is expected to overcome the shortcomings of traditional methods and provide more reliable technical support for CPE film quality testing. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a CPE film heat sealer, which solves the technical problem that static operation in the prior art cannot reflect the performance changes of CPE film during dynamic heat sealing, resulting in deviations between the test results and actual applications.

[0006] According to one aspect, at least one embodiment of this disclosure provides a CPE film heat sealing apparatus, comprising: A base and a controller, wherein the controller is mounted on the base; A positioning component, wherein the positioning component is disposed on the base; The drive motor and the rolling hot pressing assembly are provided, wherein the drive motor is disposed on the side surface of the base and the rolling hot pressing assembly is disposed on the base; The rolling hot pressing assembly includes a heater, which is fixed on the base. A circular opening is provided on the side surface of the base, and the heater is located inside the circular opening. A heat-conducting shell is fitted around the heater, and a hot pressing wheel is fitted around the heat-conducting shell.

[0007] As a further technical solution, the outer end face of the heat-conducting shell is provided with several slots, the inner side of the heat-pressing wheel is inserted into the slots, the output end of the drive motor is provided with a drive gear, the outer side of the heat-pressing wheel is provided with an external gear, and the drive gear meshes with the external gear.

[0008] As a further technical solution, the side surface of the base is provided with an opening, and a pair of round rods are provided in the opening. A slider is slidably connected to the round rods, and a support spring is fitted on the round rods.

[0009] As a further technical solution, a pair of guide wheels are rotatably connected to the surface of the slider, with a gap between the guide wheels and the hot pressing wheel, and a support wheel is rotatably connected to the surface of the slider, with the support wheel attached to the lower end face of the hot pressing wheel.

[0010] As a further technical solution, the positioning component includes a pair of fixing rods, both of which are fixed to the two ends of the base surface, with a gap between the pair of fixing rods, the pair of fixing rods being distributed vertically, and a correction plate connecting the pair of fixing rods at the same horizontal height.

[0011] As a further technical solution, a limiting plate is slidably connected to the fixed rod. Bolts are threadedly connected to both ends of the limiting plate. A positioning block is provided at one end of each bolt, and the positioning block is supported between a pair of fixed rods.

[0012] As a further technical solution, the limiting plate is bent downwards at the middle position, and the bending transition of the limiting plate matches the curvature of the hot press roller surface.

[0013] As a further technical solution, a pair of sliding grooves are provided on the surface of the base, and a protective cover is slidably inserted into the sliding grooves.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: 1. The beneficial effect of the rolling hot pressing assembly in this disclosure is that the heater and the heat-conducting shell work together to efficiently transfer heat to the hot pressing wheel. The drive structure composed of the drive motor, drive gear and external gear realizes the rolling hot pressing of the hot pressing wheel. The round rod, slider, support spring, guide wheel and support wheel cooperate with each other to guide the CPE film into the hot pressing area and provide support. This assembly simulates the dynamic heat sealing process, the test results are more consistent with actual applications, and the hot pressing is uniform, which improves the accuracy of the test.

[0015] 2. In this disclosure, the beneficial effect of the positioning component is that the fixing rod and the straightening plate provide space for the CPE film to be introduced and initially correct its position. The adjustable limiting plate, together with the bolts and anti-slip blocks, can accurately fix the limiting plate according to the condition of the CPE film. The arc-shaped bending transition structure in the middle of the limiting plate allows the CPE film to be guided with the shape of the hot pressing roller and kept flat. This component ensures that the CPE film accurately enters the hot pressing position, avoids deviation, and improves the hot pressing effect and detection reliability. Attached Figure Description

[0024] like Figures 1-4 As shown, it illustrates a CPE film heat sealer according to an embodiment of the present disclosure, comprising: Base 1 and controller 2, wherein the controller 2 is disposed on the base 1; Positioning component 5, wherein the positioning component 5 is disposed on the base 1; The drive motor 3 and the rolling hot pressing assembly 4 are provided, wherein the drive motor 3 is disposed on the side surface of the base 1 and the rolling hot pressing assembly 4 is disposed on the base 1; The rolling hot pressing assembly 4 includes a heater 4-1, which is fixed on the base 1. A circular opening 4-2 is provided on the side surface of the base 1, and the heater 4-1 is located inside the circular opening 4-2. A heat-conducting shell 4-3 is fitted around the heater 4-1, and a hot pressing wheel 4-4 is fitted around the heat-conducting shell 4-3. Several slots 4-5 are provided on the outer end face of the heat-conducting shell 4-3, and the hot pressing wheel 4-4 is inserted into the slots 4-5. A drive gear 4-6 is provided at the output end of the drive motor 3, and an external gear 4-6 is provided on the outside of the hot pressing wheel 4-4. -7, the drive gear 4-6 meshes with the external gear 4-7, the side surface of the base 1 has an opening 4-8, a pair of round rods 4-9 are provided in the opening 4-8, a slider 4-10 is slidably connected to the round rods 4-9, a support spring 4-11 is fitted on the round rods 4-9, a pair of guide wheels 4-12 are rotatably connected to the surface of the slider 4-10, there is a gap between the guide wheels 4-12 and the hot pressing wheel 4-4, a support wheel 4-13 is rotatably connected to the surface of the slider 4-10, and the support wheel 4-13 is attached to the lower end face of the hot pressing wheel 4-4.

[0025] In some examples, to achieve efficient, uniform, and non-limited-to-one-location hot-pressing results when hot-pressing CPE film, a rolling hot-pressing assembly 4 is designed. This assembly includes a heater 4-1 fixed on a base 1. A circular opening 4-2 on the side surface of the base 1 provides installation space for the heater 4-1, allowing it to stably perform its heating function within the circular opening 4-2. A heat-conducting shell 4-3 fitted outside the heater 4-1 efficiently conducts heat. The hot-pressing roller 4-4 fitted outside the heat-conducting shell 4-3 is a key component for directly hot-pressing the CPE film. Several slots 4-5 on the outer end face of the heat-conducting shell 4-3 cooperate with the inner side of the hot-pressing roller 4-4, ensuring a tight connection between the hot-pressing roller 4-4 and the heat-conducting shell 4-3 for effective heat transfer. The drive gear 4-6 at the output end of the drive motor 3 engages with the external gear on the outside of the hot-pressing roller 4-4. The meshing of gears 4-7 forms the driving structure for the rotation of the hot pressing wheel 4-4. When the drive motor 3 starts, the drive gear 4-6 rotates, driving the hot pressing wheel 4-4 to rotate synchronously through the external gear 4-7, achieving rolling hot pressing. A pair of round rods 4-9 are set inside the opening 4-8 on the side surface of the base 1. The slider 4-10 set on the round rods 4-9 can slide vertically up and down on the round rods 4-9. The support spring 4-11 fitted on the round rods 4-9 provides elastic support for the slider 4-10. A pair of guide wheels 4-12 rotatably connected to the surface of the slider 4-10 are spaced apart from the hot pressing wheel 4-4 to guide the CPE film into the hot pressing area. The support wheel 4-13 rotatably connected to the surface of the slider 4-10 is attached to the lower end face of the hot pressing wheel 4-4, providing support for the CPE film during the hot pressing process, ensuring that the hot pressing wheel 4-4 and the CPE film are tightly attached to achieve the effect of hot pressing. The rotation speed of the hot pressing wheel 4-4 represents the residence time on the surface of the CPE film.

[0026] like Figures 1-4 As shown in the figure, the positioning component 5 in this embodiment includes a pair of fixing rods 5-1. The pair of fixing rods 5-1 are fixed at both ends of the surface of the base 1. There is a gap between the pair of fixing rods 5-1. The pair of fixing rods 5-1 are distributed vertically. A straightening plate 5-2 is connected between the pair of fixing rods 5-1 at the same horizontal height. A limiting plate 5-3 is slidably fitted onto the fixing rods 5-1. Bolts 5-4 are threadedly connected to both ends of the limiting plate 5-3. A positioning block 5-5 is provided at one end of the bolt 5-4. The positioning block 5-5 is supported between the pair of fixing rods 5-1.

[0027] In some examples, during the hot-pressing test of CPE film, a positioning component 5 is designed to ensure that the CPE film can accurately enter the hot-pressing position and avoid displacement that would affect the hot-pressing effect. This component includes a pair of fixing rods 5-1 fixed at both ends of the surface of the base 1. The pair of fixing rods 5-1 are distributed vertically with a gap between them, providing space for the introduction of the CPE film. A correction plate 5-2 connected between the pair of fixing rods 5-1 at the same horizontal height can initially correct the position of the CPE film, keeping it on the correct path during the introduction process. A limiting plate 5 is slidably fitted onto the fixing rods 5-1. -3, can be adjusted back and forth on the fixing rod 5-1 according to the width and position requirements of the CPE film, and the insertion depth of the CPE film can be changed. The two ends of the limiting plate 5-3 are connected by bolts 5-4 through threads. The positioning block 5-5 set at one end of the bolts 5-4 is supported between a pair of fixing rods 5-1. By turning the bolts 5-4, the pressure between the positioning block 5-5 and the fixing rod 5-1 can be adjusted, thereby fixing the position of the limiting plate 5-3. The limiting plate 5-3, together with the straightening plate 5-2, limits and guides the CPE film from multiple directions to ensure that the CPE film can accurately enter the hot pressing position along the predetermined path.

[0028] For example, such as Figure 1 As shown, the limiting plate 5-3 is bent downwards at the middle position, and the bending transition of the limiting plate 5-3 matches the surface curvature of the hot press roller 4-4.

[0029] In some examples, the arc-shaped transition structure of the limiting plate 5-3 allows the CPE film to be guided by the shape of the hot press roller 4-4 after it is placed in, so that the CPE can remain flat throughout the process.

[0030] For example, such as Figure 1 As shown, a pair of sliding grooves 6 are provided on the surface of the base 1, and a protective cover 7 is slidably inserted into the sliding grooves 6.

[0031] In some examples, by providing a groove 6 and a protective cover 7, the hot pressure roller 4-4 can be enclosed inside, which can increase safety and prevent burns.

[0032] In practical use: First, adjust the position of the limiting plate 5-3 on the fixing rod 5-1 according to the width and position requirements of the CPE film. Tighten the bolt 5-4 to fix the limiting plate 5-3 with the anti-slip block 4-10. Pass the CPE film between the fixing rod 5-1 and the straightening plate 5-2 of the positioning assembly 5. Use the straightening plate 5-2 and the limiting plate 5-3 to correct the position. Start the drive motor 3, and the drive gear 4-6 will drive the hot pressing wheel 4-4 to rotate. Place the CPE film on the guide wheel 4-12 and the support. Between support rollers 4-13, guide roller 4-12 guides the CPE film into the hot pressing area. Hot pressing roller 4-4 rolls and hot presses the CPE film. During the hot pressing process, support roller 4-13 provides support for the CPE film, ensuring that hot pressing roller 4-4 and CPE film are tightly adhered. After hot pressing is completed, turn off drive motor 3 and remove the CPE film. If it is necessary to start hot pressing in the middle position, the slider 4-10 can be manually pressed down to open the gap between support roller 4-13 and hot pressing roller 4-4 before inserting the film.
