[0010] Preferably, the side wall of the support platform is provided with a fixing plate, and the fixing plate is provided with adjusting bolts and a top plate for adjustment and locking, so as to securely fix the entire device in the working position.

[0011] Preferably, the transmission mechanism includes a connecting beam connected to the output end of the electric lifting rod, and connecting rods at both ends connected to the connecting beam and the scraper respectively, forming a stable parallel linkage mechanism to ensure that the scraper always maintains a parallel posture to the bottom mold surface during movement.

[0012] Preferably, the device further includes a tray for collecting and cleaning waste, the tray being positioned below the bottom mold to facilitate the collection and processing of waste.

[0020] 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. Example

[0021] refer to Figure 1-6 The illustrated bottom die surface cleaning device includes a bottom die 3 for cleaning the surface of the front end of a machine body 1, such as a plastic extruder. The device mainly includes a support platform and a cleaning assembly 5 mounted on the platform.

[0022] In one embodiment of this work, the support platform consists of a platform and two sets of legs 7 intersecting at the bottom of the platform. The platform has various functional slots. Among them, the positioning slot 42 is used for quick and accurate positioning of the cleaning assembly 5 during installation. The support slot 41 cooperates with the fixing block 56 at the bottom of the cleaning assembly 5. When the fixing block 56 is inserted into the support slot 41, it prevents the cleaning assembly 5 from shaking or shifting during operation, ensuring operational stability. Furthermore, a cleverly designed storage slot 43 is located at the bottom of the platform. When the equipment is not in use, the legs 7 can be rotated and stored there, making storage and transportation very convenient. To further enhance stability, a fixing plate 6 is also provided on the side of the support platform. By rotating the adjusting bolt 61, the top plate 62 can be pressed against the ground or other fixed objects, firmly locking the entire device in the working position.

[0023] In one embodiment of this work, the cleaning assembly 5 is the core component for performing the cleaning action. It is based on a support frame, which integrates an electric lifting rod 51 (power source), a transmission mechanism, and a scraper 54 as the execution component. The output end of the electric lifting rod 51 is fixedly connected to a connecting beam 52. Two parallel connecting rods 53 are hinged to both ends of the connecting beam 52, and the other end of each connecting rod 53 is connected to a crossbeam 55 on which the scraper 54 is fixed. Specifically, the scraper 54 employs a combined design, with its upper part being a rigid metal scraper and its lower part being a row of dense steel wire brushes. This design constitutes a translational mechanism, ensuring that when the electric lifting rod 51 performs linear up-and-down movement, it drives the scraper 54 to maintain a horizontal posture for smooth up-and-down scraping.

[0024] As one implementation of this embodiment, the device is also equipped with a controller 2, which is connected to the electric lifting rod 51 via a cable. The operator can easily start or stop the cleaning process using this controller 2. Simultaneously, a tray 4 can be placed directly below the bottom mold 3 to collect plastic waste scraped from the mold surface, keeping the site clean.

[0025] The working principle of this device is as follows: When cleaning is required, first move the device to the front of the machine body 1 and install the cleaning assembly 5 into the positioning slot 42 and support slot 41 of the support platform. Place the tray 4 for collecting waste. After the machine body 1 has finished discharging waste, the operator starts the controller 2, and the electric lifting rod 51 starts to operate. Its telescopic movement is converted into a stable, parallel reciprocating scraping motion of the scraper 54 in the vertical direction through the transmission mechanism composed of the connecting beam 52 and the connecting rod 53. During the scraping process, the rigid scraper at the top of the scraper 54 first contacts the surface of the bottom mold 3, scraping away large, softer residues; then, the steel wire brush at the bottom performs a fine scrubbing of the surface, removing stubborn thin layers of charred material and impurities. The scraped waste falls into the tray 4 below. After several reciprocating movements, the surface of the bottom mold 3 is cleaned. The entire process requires no manual intervention, is safe and efficient.

[0027] Components not described in detail in this article are existing technologies.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
