Technical Field

[0001] This utility model relates to the field of plastic suction cup technology, specifically to a plastic suction cup forming and heating device. Background Technology

[0002] Plastic suction cups are formed by vacuum forming machines, also known as thermoforming machines. These machines use heated and plasticized thermoplastic rolls of materials such as PVC, PE, PP, PET, and HIPS to form various shapes of high-end packaging boxes, frames, and other products. Vacuum forming machines typically consist of unwinding equipment, conveying equipment, heating equipment, compressed air equipment, cooling equipment, and demolding equipment. The heating equipment in vacuum forming machines usually uses an electric furnace.

[0003] The electric furnace is heated by a heating plate. The heating blocks on the existing heating plate are usually fixed. However, when producing different types of trays, different positions need to be heated. The existing heating plate can only heat the whole area. If the whole area is heated, the edges of the area to be vacuum-formed will be easily deformed during the subsequent vacuum forming process, thereby reducing the quality of the formed product. Therefore, we propose a plastic suction cup forming heating equipment to solve this technical defect. Utility Model Content

[0011] As a preferred embodiment of this utility model, the threaded adjusting rod is provided with an adjusting head at the same center on its outer side.

[0012] By adopting the above technical solution, the movement of the heating block on the insert can be adjusted by rotating the adjusting head to drive the threaded adjusting rod to screw in and out of the threaded adjusting cylinder, thereby changing the distance between the heating block and the sheet material and ensuring the heating effect. In addition, the insertion of the insert and the heating block makes it easy to replace heating blocks of different shapes and sizes.

At the same time, heating blocks of corresponding shapes are inserted into the adjusting component according to the shape of the heating and blistering area, so that the heating blocks correspond one-to-one with the blistering heating area.

[0018] Furthermore, the distance between the heating block and the heating sheet can be changed by adjusting the adjustment components to ensure the heating effect.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 3 The plastic suction cup forming heating equipment in this embodiment mainly consists of a chassis base 1, a magnetic suction plate 2, an electromagnet 3, an adjustment component, a heating block 7, a power connector 1 8, a power connector 2 9, a fixing frame 10, and an adjustment head 11. By rationally designing the structure and connection relationship of each component, this equipment achieves independent heating according to the position and shape of the plastic suction cup heating and forming area, avoiding the problem of edge deformation caused by overall heating, and improving the quality of the formed product.

[0025] The chassis base 1, as the main support structure of the entire equipment, is made of high-strength, high-temperature resistant metal materials, such as aluminum alloy. It has good heat dissipation performance and structural stability, and can withstand the heat and vibration generated during equipment operation. The chassis base 1 is rectangular in shape, with different functional components at the top and bottom.

[0026] The magnetic plate 2 is fixed to the lower surface of the chassis base 1. It is preferably an iron plate, but it is not limited to iron plates. It can also be other magnetic materials that can be attracted by an electromagnet. The magnetic plate 2 is fixed to the chassis base 1 by welding or bolting to ensure a firm connection and prevent loosening during equipment operation.

[0027] Multiple electromagnets 3 are magnetically attracted to the magnetic suction plate 2. The number of electromagnets 3 is determined according to the number and position of the heating and forming area of ​​the plastic suction cup in actual production. The electromagnets 3 adopt standard electromagnet models, which have good magnetism and stability. The electromagnets 3 generate magnetism by passing electricity, thereby attracting to the magnetic suction plate 2. The magnetism disappears after the power is turned off, making it easy to adjust their position.

[0028] The adjustment assembly is mounted on the electromagnet 3 and mainly includes a threaded adjustment cylinder 4, a threaded adjustment rod 5, and a plunger 6.

[0029] The threaded adjusting cylinder 4 is fixed to the bottom of the lower end of the electromagnet 3 and is fixed together with the electromagnet 3 by means of threaded connection or welding. The threaded adjusting cylinder 4 has an internal thread for cooperating with the threaded adjusting rod 5.

[0030] The upper end of the threaded adjusting rod 5 is threadedly connected to the threaded adjusting cylinder 4, and the lower end is inserted into the outside of the insert cylinder 6. An adjusting head 11 is fixed to the outside of the threaded adjusting rod 5 with the same center. The adjusting head 11 is made of anti-slip material, such as rubber, so that the operator can easily rotate the adjusting head 11 to drive the threaded adjusting rod 5 to rotate inside the threaded adjusting cylinder 4.

[0031] The insert 6 is connected and fixed to the heating block 7. The insert 6 has an insertion hole inside that matches the lower end of the threaded adjustment rod 5. It can be quickly installed and disassembled by insertion, making it easy to replace heating blocks 7 of different shapes and sizes.

[0032] The heating block 7 is detachably mounted on the insert 6 of the adjustment component. According to the forming shape of the plastic suction cup heating and blistering area, the heating block 7 of the corresponding shape is selected for insertion and installation. The heating block 7 is made of high-efficiency heating material, such as ceramic heating element, which has the advantages of fast heating speed, uniform heating and long service life. The heating block 7 is electrically connected to a power plug 8 for connection to an external power source.

[0033] The first power connector 8 is fixed to the upper surface of the heating block 7, and the second power connector 9 is electrically connected to the upper surface of the chassis 1. A connecting wire is inserted between the first power connector 8 and the second power connector 9 to connect the heating block 7 to the power supply and control circuit through the wire, so as to realize the controlled heating of the heating block 7. The power supply and control circuit are located inside the chassis 1.

[0034] The upper four corners of the chassis base 1 are provided with fixing brackets 10. The fixing brackets 10 are made of metal and are fixed to the chassis base 1 by welding. The fixing brackets 10 have fixing holes. By passing the fixing screws through the fixing holes, the fixing brackets 10 can be installed on the carrier to realize the installation and fixation of the whole equipment.

[0035] Structural design principles and usage steps

[0036] First, install the chassis base 1 in a suitable position on the vacuum forming machine using the mounting bracket 10, and use fastening screws to firmly connect the mounting bracket 10 to the carrier through the mounting holes.

[0037] Then, based on the location of the heating and vacuum forming area of ​​the product and the forming shape of the heating and vacuum forming area, determine the number and location of the electromagnets 3 to be installed, energize the electromagnets 3 so that they are attracted to the magnetic suction plate 2, and ensure that the number of electromagnets 3 corresponds to the number and location of the vacuum forming heating area.

[0038] Based on the shape of the heating and vacuum forming area, select the corresponding heating block 7 and insert it into the insert 6 of the adjustment component to ensure a secure connection.

[0039] By rotating the adjusting head 11, the threaded adjusting rod 5 is driven to screw in and out of the threaded adjusting cylinder 4, adjusting the distance between the heating block 7 on the insert 6 and the heating sheet to ensure the heating effect. During the adjustment process, it can be finely adjusted multiple times according to actual needs until the optimal heating distance is achieved.

[0040] Insert the connecting wire between the first power connector 8 and the second power connector 9 to connect the heating block 7 to the power supply and control circuit, ensuring a secure electrical connection and avoiding poor contact.

[0041] Start the vacuum forming machine and simultaneously connect the power supply to the heating block 7. The heating block 7 begins to heat up. According to the settings of the control circuit, the heating blocks 7 at different positions are independently controlled to achieve precise heating of the vacuum forming area of ​​the plastic suction cup.

[0042] During the heating process, the operator can observe the heating effect in real time and further adjust the position of the heating block 7 or the heating parameters as needed.

[0043] After the plastic suction cup is formed, turn off the power to the heating block 7 to stop heating. After the equipment cools down, the heating block 7 can be cleaned and maintained, such as removing impurities and dirt from the surface of the heating block and checking the heating performance of the heating block.

[0044] If you need to replace the heating block 7 with a different shape or size, simply disconnect the wire between the power plug 1 8 and the power plug 2 9, pull the original heating block 7 out of the socket 6, insert the new heating block 7, and reconnect the wire.

[0045] To further improve the automation level and heating accuracy of the equipment, the system control of the equipment can be expanded.

[0046] A temperature sensor is installed on each heating block 7 to monitor the temperature of the heating block in real time and feed the temperature signal back to the control circuit. The control circuit automatically adjusts the heating power of the heating block 7 according to the set temperature value to achieve precise control of the heating temperature.

[0047] In summary, the plastic suction cup forming heating equipment of this utility model, through reasonable structural design and detailed implementation method, realizes independent heating of the heating and forming area of ​​the plastic suction cup, improves the quality of the formed product, and has the advantages of convenient installation, flexible adjustment and strong expandability, and has broad market application prospects.

[0048] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
