Description

Technical Field

[0001] This utility model relates to the technical field of cleaning equipment for extrusion molding nozzles, and specifically to a slit-type die head cleaning tool. Background Technology

[0002] Slit dies are a type of die used in extrusion molding equipment, and they are widely used in continuous extrusion production processes for products such as optical films, lithium battery separators, and functional coatings. Typically, after prolonged use, a significant amount of impurities and residues accumulate inside the slit. If the die is not cleaned promptly, this can easily lead to localized blockages in the slit or uneven material output.

[0003] Currently, the industry mainly relies on manual operation for cleaning slit mold heads. For example, workers can use tools such as copper brushes and bamboo knives to manually scrape off the residue on the surface of the mold head and inside the slits, and use solvents to soak and soften stubborn carbon deposits.

[0004] However, manual cleaning of mold heads often presents numerous safety hazards. For example, the mold head remains hot after use, and improper manual cleaning can result in burns to workers. Furthermore, manual cleaning introduces many uncertainties, potentially leading to incomplete cleaning. For instance, the force applied by workers scraping residue from inside the mold head is inconsistent, resulting in some residue remaining. Therefore, there is an urgent need for a slit-type mold head cleaning tool that can achieve mechanized slit-type mold head cleaning. Utility Model Content

[0005] This utility model provides a slit-type mold head cleaning tool, in which the cleaning kit is driven by a machine. On the one hand, it ensures that the force and speed of each cleaning operation are controllable and uniform when repeated cleaning operations are carried out, reducing the possibility that some residues will not be scraped off. On the other hand, it avoids safety accidents such as worker burns when cleaning high-temperature mold heads.

[0006] This utility model is achieved through the following technical solution:

[0007] A slit-type mold head cleaning tool includes: a cleaning kit for extending into the slit-type mold head to perform cleaning work, comprising at least a preliminary cleaning component, a deep cleaning component, and a wiping component; and a cleaning drive unit for driving the cleaning kit to perform cleaning work, comprising a set of working wheels and an annular drive belt fitted on the set of working wheels, wherein the preliminary cleaning component, the deep cleaning component, and the wiping component are sequentially mounted on the annular drive belt, and the movement path of each component in the cleaning kit is adapted to the cavity shape of the slit-type mold head.

[0008] As a further improvement of this utility model, the preliminary cleaning component includes a scraper kit whose dimensions are adapted to the chamber dimensions of the slit mold head.

[0009] As a further improvement of this utility model, the scraper kit includes at least one set of double scraper sets, each set of double scraper sets including two sets of symmetrically arranged scraper components. A first scraping end is formed on the side of the scraper component away from the cleaning drive part, for contacting the first inner wall of the slit mold head; a second scraping end is formed on the side of the two sets of scraper components away from each other, and the second scraping end on each of the two sets of scraper components respectively contacts two second inner walls of the slit mold head.

[0010] As a further improvement of this utility model, the sides of the two sets of scraper members away from the second scraping end are attached to each other, and a first included angle is formed between the two sets of scraper members. The first included angle is an acute angle, so that the outer wall surfaces of the two sets of scraper members form a guiding inclined surface structure.

[0011] As a further improvement of this utility model, the deep cleaning component includes a metal wool ball kit and a high-frequency drive device for driving the metal wool ball kit to move.

[0012] As a further improvement of this utility model, the wiping component includes a wiping cloth kit, the surface of which is formed with wiping surfaces for contacting the inner walls of the slit-type mold head at various locations.

[0013] As a further improvement of this utility model, the wiping cloth kit is packaged outside the elastic support member.

[0014] As a further improvement of this utility model, it also includes a displacement kit, which is connected to the cleaning drive unit and is used to drive the cleaning drive unit and the cleaning kit thereon to move.

[0015] As a further improvement of this utility model, the displacement kit includes at least one telescopic kit with one end connected to the cleaning drive unit for driving the cleaning drive unit closer to or away from the slit mold head.

[0016] As a further improvement of this utility model, the telescopic kit includes several sets of air-driven telescopic devices.

[0017] The beneficial effects of this utility model include:

[0018] (1) The initial cleaning component, deep cleaning component and wiping component in the cleaning kit are driven by a mechanized cleaning drive unit. This ensures that the cleaning force of the cleaning kit remains consistent during long-term and frequent use. The cleaning force can also be adjusted by adjusting the output power of the working wheel set according to the worker's requirements. Compared with manual cleaning, it can maintain the stability of cleaning and ensure that the residue can be scraped off in multiple cleaning operations.

[0019] (2) The preliminary cleaning component, the deep cleaning component and the wiping component are all installed on the ring drive belt. When the ring drive belt is running, the three components move simultaneously, in the same direction and along the same path. Since the three components are arranged one by one, the slit mold head can receive the three cleaning steps of preliminary cleaning, deep cleaning and wiping cleaning in sequence as each component moves through it. This enables the overall cleaning work to be carried out quickly and improves the cleaning efficiency while ensuring the degree of cleanliness.

[0020] (3) In the preferred structure, the scraper kit includes at least one set of double scraper kits, and each set of double scraper kits includes two sets of scraper pieces. Compared with using one complete set of scraper pieces to complete the scraping work on multiple inner walls inside the slit mold head at the same time, using multiple sets of scrapers to carry out the work separately can reduce the occurrence of the scraper pieces being blocked at multiple points and breaking during the scraping process, and reduce the probability of damage to cleaning tools and slit mold head.

[0021] (4) In the preferred structure, the displacement kit can move the position of the cleaning kit so that each part of the cleaning kit can smoothly enter the slit mold head and carry out the relevant cleaning work. Attached Figure Description

[0029] Example 1:

[0030] This embodiment provides a slit-type mold head cleaning tool, which includes a cleaning kit 1 and a cleaning drive unit 2.

[0031] like Figure 1 As shown, the cleaning kit 1 is used to extend into the slit-type mold head to perform cleaning work. It includes at least a preliminary cleaning component 101, a deep cleaning component 102, and a wiping component 103. The preliminary cleaning component 101 is used to initially scrape off the residue inside the slit-type mold head. It is used to first treat a large amount of residue adhering to the mold head to achieve preliminary cleaning. In this embodiment, a scraper set, a hard brush, or any component or kit that can quickly peel off loose residue can be used. The deep cleaning kit 1 is used to deeply peel off the more firmly adhered residue inside the mold head. It can further eliminate the residue that is difficult to remove in the preliminary cleaning section to achieve deep cleaning. In this embodiment, a heat-assisted scraping module, a high-frequency vibrating scraper, or any component or kit that can remove stubborn adhered residue can be used. The wiping component 103 is used to wipe the inner wall of the slit-type mold head to finely remove dust and residual film. In this embodiment, a microfiber wiping head, a vacuum nozzle, or any component or kit that can remove light residues such as dust can be used.

[0032] like Figure 1 As shown, the cleaning drive unit 2 drives the cleaning kit 1 to perform cleaning work. It includes a working wheel set 201 and a ring drive belt 202 mounted on the working wheel set 201. For example, the working wheel set 201 may include at least one drive wheel, the torque and speed of which can be adjusted. Each wheel in the working wheel set 201 is provided with teeth, and the ring drive belt 202 is provided with toothed surfaces that mesh with the teeth, thereby enabling the working wheel set 201 to drive the ring drive belt 202. Any other wheel set and drive belt mating structure is applicable to this invention. A preliminary cleaning component 101, a deep cleaning component 102, and a wiping component 103 are sequentially mounted on the ring drive belt 202. Figure 2As shown, the arrangement sequence L1 of the components of the cleaning kit 1 is opposite to the driving direction L2 of the annular drive belt 202. This ensures that when each component is driven by the annular drive belt 202 and interferes with the mold head, the preliminary cleaning component 101, the deep cleaning component 102, and the wiping component 103 sequentially perform their cleaning functions. That is, when the cleaning kit 1 passes a certain point in the mold head, it performs a complete cleaning process of preliminary cleaning, deep cleaning, and wiping. Simultaneously, as... Figure 3 As shown, the movement paths of each component in the cleaning kit 1 are adapted to the shape of the cavity of the slit-type mold head. For example, in this embodiment, the cavity shape of the slit-type mold head is a cuboid. Therefore, the movement paths of each component in the cleaning kit 1 are straight lines and parallel to the long side of the cuboid. This allows each component in the cleaning kit 1 to penetrate deep into the cavity and move smoothly within the cavity when moving along the movement path, thereby realizing the respective functions of each component in the cleaning kit 1 and completing the cleaning work inside the mold head.

[0033] Preferably, such as Figure 1 As shown, the initial cleaning component 101 includes a scraper kit whose size is adapted to the cavity size of the slit mold head, so that the scraper kit can be embedded in the cavity of the mold head and close to the inner wall of the cavity, thereby enabling the scraping off of residues during movement.

[0034] Preferably, such as Figure 1 and Figure 4 As shown, in this embodiment, the scraper kit includes three sets of double scraper sets 101-1, and each set of double scraper sets 101-1 includes two sets of symmetrically arranged scraper components 101-1a, so as to... Figure 3 Taking the display perspective as an example, a first scraping end 101-1a-1 is formed on the side of the scraper 101-1a away from the cleaning drive part 2, which is used to contact the first inner wall A01 on the left side of the slit mold head; a second scraping end 101-1a-2 is formed on the side of the two sets of scraper 101-1a away from each other, and the second scraping end 101-1a-2 on each of the two sets of scraper 101-1a respectively contacts the upper and lower second inner walls A02 in the slit mold head. In this way, the two sets of scraper 101-1a achieve the scraping work, i.e., the preliminary cleaning work, of multiple inner walls in the mold head through their respective first scraping end 101-1a-1 and second scraping end 101-1a-2.

[0035] On the one hand, the three sets of double scraper kits 101-1 ensure that the scraper kit can perform multiple scraping motions after passing through a certain point inside the mold head, thereby improving the scraping rate of residues. On the other hand, the double scraper kit 101-1 contains two separate scraper pieces 101-1a, each of which uses its own scraping end to perform preliminary cleaning work on different inner wall residues. This reduces the possibility of the scraper piece 101-1a being significantly deformed or even damaged due to multiple obstructions at the scraping end when using one set of scraper pieces 101-1a for multiple inner wall cleaning tasks. It also reduces the possibility of scratching the inner wall of the mold head due to the deformation of the scraper piece 101-1a.

[0036] Preferably, such as Figure 4 As shown, the sides of the two sets of scraper blades 101-1a away from the second scraping end 101-1a-2 are attached together, and a first included angle α is formed between the two sets of scraper blades 101-1a. The first included angle α is an acute angle, so that the outer wall surfaces of the two sets of scraper blades 101-1a form a guiding inclined surface structure 101-1a-3. With this structure, the residue scraped off by the scraper blades 101-1a can be collected by the guiding inclined surface structure 101-1a-3, so that the scraped residue can be removed together in the subsequent process.

[0037] Preferably, such as Figure 1 As shown, the deep cleaning component 102 includes a metal wool ball 102-1 kit and a high-frequency drive device 102-2 that drives the metal wool ball 102-1 kit to move. The high-frequency drive device 102-2 can drive the metal wool ball 102-1 to vibrate at a high frequency within the die head, thereby enabling the metal wool ball 102-1 to remove stubborn residues.

[0038] Preferably, such as Figure 1 As shown, the wiping component 103 includes a wiping cloth kit 103-1. The surface of the wiping cloth kit 103-1 is formed with wiping surfaces for contacting the inner walls of the slit-type mold head. This allows the wiping cloth kit 103-1 to wipe the inner walls of the mold head and remove small-sized dust and other residues when it contacts the inner walls and moves under the drive of the annular drive belt 202. Simultaneously, the wiping cloth kit 103-1 can absorb chemicals and exudate them when squeezed. Therefore, in actual use, chemicals capable of dissolving residues can be pre-absorbed into the wiping cloth kit 103-1 to further improve the residue removal rate during wiping.

[0039] Preferably, the wiping cloth kit 103-1 is packaged outside the elastic support member. The elastic support member can drive the wiping surface of the wiping cloth kit 103-1 to move outward, thereby ensuring a tight fit between the wiping surface and the inner wall of the mold head, and further improving the wiping effect.

[0040] Example 2:

[0041] The difference between this embodiment and Embodiment 1 is that, in this embodiment, the slit-type mold head cleaning tool also includes a displacement kit 3, such as... Figure 3 As shown, the displacement kit 3 is connected to the cleaning drive unit 2 and is used to move the cleaning drive unit 2 and the cleaning kit 1 on it. By moving the cleaning drive unit 2, it is ensured that each component in the cleaning kit 1 installed on it can smoothly enter the slit mold head to carry out cleaning work. The displacement kit 3 can be any component or kit that can control the movement of the cleaning drive unit 2, such as a robotic arm.

[0042] Preferably, such as Figure 1 As shown, the displacement kit 3 includes at least one telescopic kit 301 connected at one end to the cleaning drive unit 2 for driving the cleaning drive unit 2 to approach or move away from the slit mold head. This structure can control the depth of each component in the cleaning kit 1 inside the mold head, so that when there is a lot of residue, at least one cleaning operation is carried out in a shallower area first, and then the cleaning operation is carried out in a deeper area, thereby ensuring that the cleaning operation is more thorough and the cleaning effect is better.

[0043] Preferably, the telescopic kit 301 includes several sets of pneumatic telescopic devices. In this embodiment, four sets of pneumatic telescopic devices are used, respectively located above and below both ends of the cleaning drive unit 2. The pneumatic telescopic devices are lightweight, which helps to make the overall cleaning tool lighter. At the same time, their telescopic range can be more precisely controlled to meet high-precision telescopic requirements. Especially when making deep movements, it can prevent the components in the cleaning kit 1 from contacting the inner wall of the mold head too tightly, thus avoiding scratches and damage during cleaning.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
