Description

Technical Field

[0001] This utility model relates to the field of threshold processing technology, specifically a threshold processing cutting machine. Background Technology

[0002] The elevator door sill is the step on the elevator landing door. It guides the elevator car door and landing door, and has roller grooves for opening and closing the elevator door. Therefore, the sill is particularly important in the operation of the elevator. The elevator door sill needs to be cut during the manufacturing process to a length suitable for the elevator door, so as to facilitate the subsequent installation of the sill.

[0003] A search of the utility model patent with publication number CN216028457U reveals an elevator sill cutting device. This device, through the installation of a dust-collecting protective component, effectively protects the saw blade, preventing accidental contact during cutting and improving safety. It also absorbs the dust generated during cutting, effectively preventing dust from escaping and harming the health of operators. This solves the problems of low safety, susceptibility to accidents, and inability to collect cutting dust in existing cutting devices. However, it has certain shortcomings in use. While the dust-collecting protective shell moves downwards to meet the sill to be cut, it does not contact the worktable surface due to the sill's influence. Although this prevents accidental contact with the saw blade, the sill itself has roller grooves. The dust-collecting protective shell overlaps with the top of the sill without sealing these grooves. During cutting, some dust and metal fragments can still easily escape and splash through the roller grooves, reducing its safety performance. Therefore, this application proposes a cutting machine for sill processing. Utility Model Content

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0027] The cutting machine for processing sills provided in this embodiment is mainly used to solve the problem that existing cutting machines have defects in the dust extraction protective shell when cutting sills, resulting in poor safety protection. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-6 Please provide a detailed explanation:

[0028] Cutting machines for processing sills include:

[0029] A base 1 is provided with a protective cover 2. Preferably, the protective cover 2 is made of transparent plastic material (such as polycarbonate), allowing personnel to observe its interior. The protective cover 2 has entry points 3 on both opposite sides, allowing a sill to be placed on the base 1 through the two entry points 3. The base 1 has two first latex blocks 4, each corresponding to one of the two entry points 3. When the sill passes through the two entry points 3, the soft and deformable nature of the first latex blocks 4 allows the sill to be placed on the base 1. The groove at the bottom of the sill is sealed. A slot 5 is provided on the inner wall of one side of the entrance 3. An insert plate 6 is movably inserted into the slot 5. A second latex block 7 is provided on the insert plate 6. When the sill is placed on the base 1, under the action of gravity, the insert plate 6 slides down along the slot 5. The second latex block 7 contacts the top of the sill. Utilizing the soft and deformable properties of the second latex block 7, the roller groove at the top of the sill is sealed. With the cooperation of the insert plate 6, the first latex block 4 and the second latex block 7, the two ends of the protective cover 2 are sealed in the entrance 3.

[0030] The cutting mechanism 8 includes a guide rod 801 that rotates through one side of the protective cover 2. A mounting plate 802 and a handle 803 are mounted on the guide rod 801. Preferably, the mounting plate 802 is located inside the protective cover 2, and the handle 803 is located outside the protective cover 2. A motor 804 is mounted on the mounting plate 802, and a cutting disc 805 is fixed to the output shaft of the motor 804. A cutting groove 806 corresponding to the cutting disc 805 is formed on the base 1. When the base is placed on the base 1, the motor 804 rotates the cutting disc 805. At this time, the handle 803 is held to rotate the guide rod 801, thereby rotating the mounting plate. 802 rotates around the guide rod 801, causing the cutting disc 805 to cut the sill. By opening the cutting groove 806, the cutting disc 805 can be movably inserted into the cutting groove 806, thereby completely cutting off the sill. The cutting process is short. The cutting disc 805 cuts the sill inside the protective cover 2. Due to the cooperation of the insert plate 6, the first latex block 4 and the second latex block 7, the two ends of the protective cover 2 are sealed with the entrance 3, so that the dust generated by cutting will not escape to the outside, and the metal fragments generated by cutting will not splash to the outside, thereby improving the safety protection.

[0031] The dust collection mechanism 9 includes a fan 901 mounted on the protective cover 2. The exhaust port of the fan 901 is connected to the protective cover 2 by an air pipe 902. A filter cylinder 903 is connected to the air pipe 902. A filter screen 904 is installed inside the filter cylinder 903. During cutting, the fan 901 exhausts air to the outside and draws air into the protective cover 2. Under the action of air extraction, the dust and metal debris generated during cutting are drawn into the filter cylinder 903, and then filtered by the filter screen 904. The clean airflow is discharged to the outside, and the dust and metal debris are trapped in the filter cylinder 903 to play the role of dust prevention and collection of impurities.

[0032] In this design, the sill passes through two inlets 3 and is placed on the base 1. With the cooperation of the insert plate 6, the first latex block 4, and the second latex block 7, the two inlets 3 at both ends of the protective cover 2 are sealed. The external control lever 803 enables the cutting disc 805 to cut the sill inside the protective cover 2, effectively preventing dust and metal debris from escaping and splashing to the outside. The dust is then removed and collected by the dust collection mechanism 9, thereby improving safety protection.

[0033] like Figure 3 As shown, in this embodiment, a spring 10 is connected between the insert plate 6 and the inner wall of the slot 5. By setting the spring 10, the elastic force of the spring 10 is used to make the downward pressure of the insert plate 6 greater, so that the first latex block 4 and the second latex block 7 can better seal the groove on the sill.

[0034] like Figure 1 and Figure 3 As shown, in this embodiment, a connecting rod 11 that slides through the protective cover 2 is connected between the two insert plates 6. Preferably, the connecting rod 11 is U-shaped, with its two ends connected to the two insert plates 6 respectively, so that pulling the connecting rod 11 upward can drive the two insert plates 6 to slide synchronously, making it more convenient and quick to install or remove the sill.

[0035] like Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, a receiving groove is constructed inside the base 1, and the cutting groove 806 is connected to the receiving groove. A collection frame 12 located in the receiving groove is slidably inserted on one side of the base 1. During the cutting process, some of the debris generated by cutting will fall into the cutting groove 806. By constructing a receiving groove inside the base 1 and slidably inserting the collection frame 12, some of the debris generated by cutting can fall into the collection frame 12 through the cutting groove 806, so as to collect the debris and facilitate subsequent cleaning.

[0036] like Figure 2 As shown, in this embodiment, the bottom of the filter cylinder 903 is connected to the receiving tank by a discharge pipe 13. A valve is provided on the discharge pipe 13. When the blower 901 is working normally, the valve on the discharge pipe 13 is closed, which effectively draws air into the protective cover 2 and traps the impurities inside the filter cylinder 903. When the blower 901 stops working or there are too many impurities trapped in the filter cylinder 903, the valve is opened, and the impurities in the filter cylinder 903 flow through the discharge pipe 13 to the collection frame 12, which is convenient for subsequent centralized cleaning, thereby improving practicality.

[0037] like Figure 4As shown, in this embodiment, a connecting seat 14 is provided on the base 1, and the guide rod 801 rotatably passes through the connecting seat 14. A torsion spring 15 sleeved on the guide rod 801 connects the connecting seat 14 and the mounting plate 802. By providing the connecting seat 14 on the base 1 and the torsion spring 15 between the mounting plate 802 and the connecting seat 14, in the initial state, under the torsional force of the torsion spring 15, the cutting disc 805 is inclined to a certain height (e.g., Figure 4 As shown in the figure, it facilitates the sliding and unloading of the sill. During cutting, the handle 803 can be cranked normally.

[0038] like Figure 1 As shown, in this embodiment, a fixing member 16 is provided on both sides of the base 1 and the protective cover 2. It is used to fix the sill. The section of the sill inside the protective cover 2 is cut. By setting two fixing members 16, the two fixing members 16 respectively fix the two ends of the sill, so that the sill will not be displaced by the stress of cutting during the cutting process, so as to ensure the cutting quality and improve the practicality.

[0039] like Figure 6 As shown, in this embodiment, the fixing member 16 includes an L-shaped frame 1601 mounted on the base 1. A lead screw 1602 is threaded through the L-shaped frame 1601. A pressure plate 1603 is rotatably connected to the end of the lead screw 1602. A guide rod 1604 with its end sliding through the L-shaped frame 1601 is provided on the pressure plate 1603. When the sill is located on the base 1, the sill is located below the L-shaped frame 1601. At this time, the lead screw 1602 is twisted to rotate and move, thereby driving the pressure plate 1603 to press the sill. The pressing force is used to fix the sill. The method of fixing or unfixing is relatively simple and convenient.

[0040] The working process of this utility model is as follows: The sill passes through two inlets 3 and is placed above the base 1. The first latex block 4 seals the slot at the bottom of the sill. The insert plate 6 moves downward under the action of gravity. The second latex block 7 seals the slot at the top of the sill. The motor 804 drives the cutting disc 805 to rotate. At this time, the hand handle 803 drives the guide rod 801 to rotate, thereby causing the cutting disc 805 to cut the sill. By opening a cutting groove 806, the cutting disc 805 can be movably inserted into the cutting groove 806, thereby completely cutting off the sill. The cutting disc 805 cuts the sill inside the protective cover 2. With the cooperation of the insert plate 6, the first latex block 4, and the second latex block 7, the two ends of the protective cover 2 are sealed at the inlets 3, so that the dust generated during cutting will not escape to the outside, and the metal fragments generated during cutting will not be splashed to the outside, thereby improving the safety protection performance. At the same time, during the cutting process, the fan 901 exhausts air to the outside and draws air into the protective cover 2. Under the action of air extraction, the dust and metal fragments generated during cutting are sucked into the filter cartridge 903, and then filtered by the filter screen 904, and the clean airflow is discharged to the outside, while the dust and metal fragments are trapped in the filter cartridge 903, so as to play the role of dust prevention and impurity collection.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
