Description

Technical Field

[0001] This utility model relates to the field of sponge processing technology, and more specifically to a hot pressing molding device for sponge processing. Background Technology

[0002] Environmentally friendly sponges are widely used in cleaning, water absorption, anti-slip, heat insulation, and sound insulation, reducing environmental pollution and harm, and improving people's quality of life and health. Generally, hot pressing equipment, to meet the needs of long-term operation, especially for large-volume orders, has strict limitations on the connection strength between its various structures. Molds, as parts that are not frequently disassembled, are usually designed with robust connection structures to ensure that the equipment's processing accuracy does not deviate.

[0003] However, in some special circumstances, factories may need to temporarily change molds. In such cases, if the mold currently set on the equipment cannot be quickly changed according to production needs, the length of time spent waiting for the mold to be changed and debugged will determine the timing of resumption of work. Obviously, the length of time waiting for mold change and debugging will fluctuate depending on the skill level of the production line technicians. The delay in resumption of work caused by excessive time will also result in a certain loss of production capacity for the production line. Furthermore, if the debugging is not in place, the pressure applied by the equipment to the mold cavity will be uneven, leading to inconsistent product quality, increased equipment and mold wear, increased energy consumption, and other problems, which will also increase maintenance costs.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The hot pressing molding device for sponge processing involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Combination Figures 1-3 As shown, this utility model provides a hot pressing molding device for sponge processing, including a base 1, a lifting assembly 2, an upper pressing assembly 3, a lower pressing assembly 4, and a buffer assembly 5. The lifting assembly 2 is disposed on the top of the base 1, the upper pressing assembly 3 is sleeved on the bottom of the lifting assembly 2, the lower pressing assembly 4 is installed on the top of the buffer assembly 5, and the buffer assembly 5 is installed at the bottom of the inner cavity of the base 1.

[0024] The base 1 includes at least a support body 101, and the buffer assembly 5 consists of a fixed column 501, a buffer plate 502, a buffer cylinder 503, and a buffer spring 504. The fixed column 501 is fixedly installed at the bottom of the inner cavity of the support body 101, while the buffer plate 502 is movably engaged within the inner cavity of the support body 101. The buffer cylinder 503 is fixedly installed at the bottom of the buffer plate 502, while the fixed column 501 is movably sleeved inside the buffer cylinder 503. The buffer spring 504 abuts against the fixed column 501 and the buffer cylinder 503, ensuring that when the upper sponge is hot-pressed, the buffer spring 504 presses down on the buffer plate 502, providing cushioning for the buffer plate 502 and thus improving the service life of the device.

[0025] Sponge production lines typically produce large items, but also some small items, depending on the needs of the final product. Therefore, based on the technical solution of this utility model, simply put, the target specifications of the hot pressing device can be obtained by adaptively enlarging or shrinking the specifications of each actuator. However, from the perspective of general equipment, replacing the actuators is more feasible, that is, achieving the technical objective through a set of machine tools and multiple sets of molds of different specifications. This form is also the most economical and commonly used choice. The technical solution of this utility model achieves the production state of processing sponges of the required specifications and styles by directly replacing the molds, which also meets the production needs of most manufacturing enterprises.

[0026] The base 1 also includes a support body 102 and casters 103. The support body 102 is symmetrically installed at the bottom of the carrier 101, and the casters 103 are fixedly connected to the bottom end of the support body 102. This structure can be set with reference to the existing flatbed cart structure, which is equivalent to setting casters for the equipment of this utility model. It can be configured in a suitable position as needed and put into production. When maintenance is required, it can also be quickly withdrawn from the work position. If necessary, the casters 103 should be equipped with a locking structure, such as a locator. The locator is set with reference to the existing general positioning casters to prevent the shaking of the equipment during operation from causing it to deviate from its original work position.

[0027] The lifting assembly 2 consists of a fixed body 201, a motor 202, a gear 203, a guide rod 204, a rack 205, and a clamping device 206. The fixed body 201 is fixedly mounted on the top side of the carrier 101, and the motor 202 is nested inside it. The output shaft of the motor 202 is fixedly connected to the gear 203 via a coupling, ensuring precise transmission. The guide rod 204 is movably clamped onto the top of the caster wheel 103, and a rack 205 is provided on one side. The gear 203 and rack 205 mesh tightly, ensuring smooth motion transitions. The clamping device 206 is fixedly connected to the bottom of the guide rod 204, facilitating the starting of the motor 202. When the motor 202 starts, its output shaft drives the transmission shaft to rotate, which in turn drives the gear 203 to rotate. The meshing of the gear 203 and rack 205 allows the guide rod 204 to move downwards, thereby pushing the upper pressing assembly 3 to hot-press the sponge.

[0028] Further reference Figure 2 The guide rod 204 passes through the top of the support body 101. The guide rod 204 also has a limiting groove parallel to the rack 205 on one side of the rack 205. The support body 101 and the guide rod 204 are also provided with a limiting flange that cooperates with the guide groove. This structure is designed to ensure that the meshing between the rack 205 of the guide rod 204 and the gear 203 of the motor 202 will not easily cause circumferential leakage, making it more stable.

[0029] The upper pressing assembly 3 consists of an upper mold 301, a heating wire 302, a retaining shaft 303, a switch 304, and a retaining spring 305. The upper mold 301 is located outside the retainer 206, and the heating wires 302 are symmetrically installed inside it. The retaining shaft 303 can be movably engaged between the upper mold 301 and the retainer 206, and the switch 304 is fixedly installed on its top. The retaining spring 305 is located on one side of the retaining shaft 303 inside the upper mold 301. This design facilitates heating the sponge through the heating wire 302, thereby increasing the molding speed. Simultaneously, when the switch 304 is pulled to one side, the retaining shaft 303 is withdrawn from the retainer 206, allowing the lifting assembly 2 and the upper pressing assembly 3 to be easily separated. This process facilitates the replacement of the upper mold 301, thereby improving the applicability of the device.

[0030] The lower pressing assembly 4 includes a lower mold 401, a retainer 402, and fixing bolts 403. The lower mold 401 is mounted on top of the buffer assembly 5, and the retainers 402 are symmetrically distributed around the lower mold 401. The fixing bolts 403 are connected to the inside of the retainer 402 by a movable snap-fit ​​mechanism. This design is both stable and easy to operate, allowing for easy removal of the fixing bolts 403 when needed, thus facilitating the replacement of the lower mold 401.

[0031] The working principle of this utility model:

[0032] First, place the sponge on top of the lower mold 401, and turn on the heating wire 302 to heat the bottom of the upper mold 301;

[0033] Next, start the motor 202. The output shaft of the motor 202 drives the transmission shaft to rotate. The transmission shaft drives the gear 203 to rotate. The gear 203 drives the rack 205 that meshes with it, causing the guide rod 204 to move downward, so that the bottom of the upper mold 301 fits against the top of the lower mold 401. Under the action of the buffer spring 504, the buffer plate 502 is pressed down to provide cushioning. After waiting for a few seconds, control the guide rod 204 to rise. Under the elastic force of the buffer spring 504, the buffer plate 502 is restored to its original position, and the molded sponge is taken out, completing the sponge processing.

[0034] Finally, pull the switch 304 to one side to remove the retaining shaft 303 from the inside of the retainer 206, thereby separating the lifting assembly 2 and the upper pressing assembly 3. Replace the upper mold 301, remove the fixing bolt 403, and replace the lower mold 401 to complete different molding requirements.

[0035] The above-mentioned operation process can be achieved by connecting the device to a general control panel with basic operating capabilities. The control panel can send instructions to various components through preset programs and circuits to achieve precise control of the device. The control panel used in this utility model can be adjusted and applied by referring to the control panel models of existing similar products, referring to the corresponding structure and function of this utility model, and combining basic electrical engineering.

[0036] For example, the control panel is connected to the motor 202, controlling its start, stop, and speed parameters by sending electrical signals. The motor 202, as the power source for the lifting assembly 2, directly determines the lifting speed and position of the upper pressing assembly 3. When the control panel receives an operation command, it calculates the required operating parameters for the motor 202 according to a preset program and sends electrical signals to the motor via the circuit. Upon receiving the signal, the motor begins to operate according to the specified parameters, driving the meshing of the gear 203 and rack 205, thereby moving the guide rod 204 up and down. A snap-fit ​​connector 206 is fixedly connected to the bottom of the guide rod 204, and the snap-fit ​​connector 206 is connected to the snap-fit ​​shaft 303 of the upper pressing assembly 3. Therefore, as the guide rod 204 moves, the upper pressing assembly 3 also rises and falls accordingly.

[0037] Meanwhile, the control panel is also connected to the heating wire 302 to control the heating temperature of the upper mold 301. During the hot pressing process of the sponge, the heating wire needs to heat the upper mold to a certain temperature to ensure that the sponge can be fully softened and conform to the shape of the mold. By adjusting the current or voltage of the heating wire, the control panel can control the heating temperature of the upper mold, thereby achieving precise control of the hot pressing process.
