Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of floor mat heat sealing, especially to a PVC floor mat heat sealing device with high efficiency and energy saving. BACKGROUND

[0002] PVC floor mats are widely used in home, business and industrial fields due to their wear resistance, slip resistance, moisture resistance, easy cleaning and aesthetic appearance. For example, in the home, PVC floor mats are usually used in the kitchen, bathroom and other areas prone to moisture; in commercial places, they are often used in hotels, shopping malls, workshops and other high-traffic areas to provide a comfortable walking experience and reduce the risk of slipping. With the growing market demand, the production scale of PVC floor mats has expanded year by year, and the automation and efficiency of the process have become the focus of industry development. However, as one of the most important steps in the production process, the technology of heat sealing has lagged behind, and many existing equipment and processes have failed to meet the high requirements of modern production for efficiency, quality and energy saving.

[0003] Traditional PVC floor mat heat sealing technology relies on the working principle of high-frequency heating equipment, which uses high-frequency electromagnetic waves to quickly heat and fuse PVC raw materials to complete the connection of materials. However, this method has obvious limitations in practical application:

[0004] 1. Low efficiency:

[0005] Traditional equipment usually completes heat sealing by moving the high-frequency heating top seat down to contact with cold raw materials. Due to the lack of pre-heating steps, the entire heat sealing process takes a long time, limiting production efficiency.

[0006] 2. Quality problems of finished products:

[0007] Direct high-frequency heating of cold raw materials results in uneven internal temperature distribution of the raw materials, which is prone to quality defects such as air bubbles, overheating or weak welding.

[0008] After heat sealing, some materials may deform, affecting the overall appearance and functionality of the finished product.

[0009] 3. High energy consumption:

[0010] High-frequency heating equipment directly heats cold raw materials, which consumes a large amount of energy, and the overall energy efficiency of the equipment is low, especially in mass production, energy waste is particularly prominent.

[0011] 4. Poor equipment stability:

[0012] In the traditional process, the high-frequency heating top seat moves frequently, which can easily cause wear and tear of mechanical parts and reduce the stability of the equipment, increasing maintenance and replacement costs.

[0013] Therefore, it is necessary to provide a PVC floor mat heat sealing device with high efficiency and energy saving. Content of the utility model

[0088] Working principle of high-efficiency energy-saving PVC floor mat heat sealing device

[0089] The device mainly drives the raw material placing table 6 to move upwards through the hydraulic system 2, so that the floor mat raw materials approach the fixed high-frequency heating top seat 5, completing the heat sealing process.

[0090] The specific principle is as follows:

[0091] 1. Raw material pretreatment:

[0092] The floor mat raw materials are first placed on the raw material placing plate 65, and the preheating hot air blower 87 in the raw material preheating structure 8 uniformly blows hot air to preheat the raw materials, making them reach the appropriate softening state.

[0093] 2. Heat sealing action:

[0094] The hydraulic system 2 provides an upward thrust to drive the raw material placing table 6 to move upwards with the preheated raw materials, contacting the high-frequency heating top seat 5.

[0095] The high-frequency heating top seat 5 uses high-frequency electromagnetic waves to quickly heat the raw materials, causing the floor mat raw materials to melt and fuse at high temperature.

[0096] 3. Cooling and shaping:

[0097] After heat sealing is completed, the hydraulic system 2 slowly lowers the raw material placing table 6, and the raw materials are shaped during the cooling process, forming a firm floor mat joint.

[0098] Auxiliary functions:

[0099] The adjusting push rod 84 and the adjusting base plate 85 can adjust the position of the preheating structure, so that the hot air can accurately act on raw materials of different shapes and sizes.

[0100] The supporting rollers 88 support both sides of the raw material placing plate 65, so that the raw material can move smoothly and stably.

[0101] Device features:

[0102] By separating the preheating from the high-frequency heat sealing, the device significantly improves the production efficiency and the finished product quality, while reducing the energy consumption, and has the advantages of high efficiency, energy saving and safety.
