Description

Technical Field

[0001] This utility model relates to a hot pressing device for sponges, which is applicable to the field of filter element processing technology. Background Technology

[0002] Filter sponges are an important component of filtration devices, primarily serving as primary filters. They offer advantages such as easy cleaning, good air permeability, and the ability to be repeatedly washed. The filtration precision of a filter sponge is mainly determined by the pore size of its internal filter holes. Smaller pores result in better filtration, but also reduced air permeability and increased clogging. To ensure effectiveness, existing filtration devices typically use two filter sponges with different pore sizes. The larger-pore sponge filters out larger particles of dust and other debris first, while the smaller-pore sponge further filters out smaller particles. This effectively ensures both filtration efficiency and air permeability, while also preventing clogging of the sponge's internal pores. However, due to the need for filtration, two sponges with different pore sizes in a filter device can usually only be simply stacked together, and cannot be glued together over a large area, making installation and disassembly very inconvenient. In some filter devices, the edges of the sponges are glued together, but since the filter sponges need to be washed and cleaned regularly, repeated washing can easily cause the sponges to come apart. Furthermore, because the sponges will deform after repeated washing, the dimensions of the two sponges after repeated washing may not match, which will cause some of the fluid flowing through the filter device to only pass through one layer of sponge, or even pass directly through the filter device without being filtered, thus adversely affecting the filtration effect of the filter device. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model proposes a hot pressing device for sponges.

[0004] The present invention employs a hot pressing device for a sponge, comprising a base plate for placing the sponge, a top plate fixedly disposed above the base plate, a hot pressing plate movable between the base plate and the top plate, a drive mechanism fixed above the top plate for driving the hot pressing plate, a heating mechanism connected to the hot pressing plate for heating the hot pressing plate, and a control device for controlling the drive mechanism and the hot pressing mechanism. The drive mechanism includes at least one driver fixed above the top plate, at least one sliding sleeve passing through the top plate and having a vertical groove inside, and guide columns of the same number as the sliding sleeves and slidably inserted into the grooves. The output shaft of the driver passes through the top plate and is fixedly connected to the hot pressing plate, and the lower end of the guide column is fixedly connected to the hot pressing plate. The entire sponge is placed on the base plate. The heating mechanism is driven by the control device to heat the hot press plate. Then, the drive mechanism is controlled to drive the hot press plate to descend and press it onto the sponge. Since the filter sponge is usually made of materials such as PET, it will soften and crystallize when heated. As a result, the part of the filter sponge near the hot press plate will shrink under the heat and pressure from the hot press plate. This process produces a single piece of filter sponge with two different pore sizes. There is no need to stack two sponges with different pore sizes or use glue to bond them. It also avoids the problems of delamination and size mismatch between the two sponges caused by repeated washing. This not only improves the convenience of disassembly and installation, but also improves the filtration effect.

[0005] Furthermore, the base plate surface has positioning grooves for placing the sponge. The positioning grooves are positioned corresponding to the hot press plate, and their dimensions are less than or equal to those of the hot press plate. These positioning grooves assist operators in placing the sponge, preventing misalignment that could lead to hot pressing failure.

[0006] Furthermore, the sliding sleeve and guide pillars are each provided with four pillars, and the lower ends of the four guide pillars are respectively connected to the corners of the hot press plate. The four guide pillars improve the stability of the hot press plate when it moves up and down, and prevent the hot press plate from shaking during the hot pressing process, which would affect the hot pressing effect.

[0007] Furthermore, the control device includes a housing, a main controller housed within the housing, a temperature sensor mounted on the hot press plate for detecting its temperature, and a time relay housed within the housing. The temperature sensor, time relay, driver, and heating mechanism are all electrically connected to the main controller. During processing, the operator sets parameters such as hot pressing temperature and time in the main controller. The main controller first controls the heating mechanism to heat the hot press plate and monitors the surface temperature of the hot press plate using the temperature sensor. Once the temperature reaches the target, the main controller controls the drive mechanism to press the hot press plate down. The time relay determines the hot pressing time; once the target time is reached, the main controller controls the drive mechanism to lift the hot press plate, completing the hot pressing process. This control device allows for automatic and controlled hot pressing, improving processing efficiency, ensuring processing accuracy, and reducing labor costs.

[0008] Furthermore, the hot pressing device also includes at least two support plates vertically arranged between the top plate and the bottom plate, with each support plate connected to one of the two sides of the top plate and the bottom plate, and the housing fixedly connected to the side of any one of the support plates. By fixing the top plate and the bottom plate with the support plates and fixing the housing to the side of the support plates, the entire hot pressing device is formed as a whole, which facilitates transportation and improves the flexibility of use.

[0009] Furthermore, the actuator is configured as a cylinder, and a circular hole is provided on the top plate at the position corresponding to the actuator for the cylinder output shaft to pass through. The cylinder body of the actuator is fixed on the top plate, and the output shaft of the actuator passes through the circular hole and is fixedly connected to the hot press plate.

[0010] Furthermore, at least four support legs are fixedly installed on the bottom surface of the base plate, and the at least four support legs are located at the corners of the base plate to improve the stability of the hot pressing device when it is placed.

[0011] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0012] The hot-pressing device for sponges in this invention has a simple structure and is easy to operate. By placing the entire sponge on the base plate and hot-pressing it with a hot-pressing plate, the entire filter sponge can have two different filtration pore sizes at the same time. This eliminates the need to stack two sponges with different pore sizes or use glue to bond them together. It also avoids the problems of delamination and size mismatch between the two sponges caused by repeated washing. This not only improves the convenience of disassembly and installation but also improves the filtration effect. Attached Figure Description

The drive mechanism 4 includes at least one driver 41 fixed above the top plate 2, at least one sliding sleeve 42 passing through the top plate 2 and having a vertically oriented groove 421 inside, and guide posts 43, the same number as the sliding sleeves 42 and slidably inserted into the grooves 421. The output shaft of the driver 41 passes through the top plate 2 and is fixedly connected to the hot pressing plate 3. The lower end of the guide post 43 is fixedly connected to the hot pressing plate 3. The entire sponge is placed on the base plate 1. The heating mechanism 5 is driven by the control device 6 to heat the hot press plate 3. Then, the driving mechanism 4 is controlled to drive the hot press plate 3 to descend and press it onto the sponge. Since the filter sponge is usually made of materials such as PET, it will soften and crystallize when heated. As a result, the part of the filter sponge near the hot press plate 3 will shrink under the heat and pressure from the hot press plate 3. This process produces a whole filter sponge with two different pore sizes. There is no need to stack two sponges with different pore sizes or use glue to bond them. It also avoids the problems of delamination and size mismatch between the two sponges caused by repeated washing. This not only improves the convenience of disassembly and installation, but also improves the filtration effect.

[0022] In a more preferred embodiment, the surface of the base plate 1 is provided with a positioning groove 11 for placing the sponge. The position of the positioning groove 11 corresponds to that of the hot press plate 3, and the size of the positioning groove 11 is less than or equal to that of the hot press plate 3.

The temperature sensor 62, time relay 63, driver 41, and heating mechanism 5 are all electrically connected to the main controller. During processing, the operator sets parameters such as hot pressing temperature and time in the main controller. The main controller first controls the heating mechanism 5 to heat the hot press plate 3 and monitors the surface temperature of the hot press plate 3 through the temperature sensor 62. When the temperature reaches the target, the main controller controls the drive mechanism 4 to drive the hot press plate 3 to press down, and determines the hot pressing time through the time relay 63. After the time reaches the target, the main controller controls the drive mechanism 4 to lift the hot press plate 3, completing the hot pressing process. The control device can automatically perform and control the hot pressing process, which not only improves processing efficiency and ensures processing accuracy, but also reduces labor costs.

[0025] In a more preferred embodiment, the hot pressing device further includes at least two support plates 12 vertically disposed between the top plate 2 and the bottom plate 1, with the at least two support plates 12 respectively connected to the two sides of the top plate 2 and the bottom plate 1, and the housing 61 fixedly connected to the side of any support plate 12.
