Description

Technical Field

[0001] This utility model relates to the field of waterstop cutting technology, and in particular to a rubber waterstop cutting machine. Background Technology

[0002] Rubber waterstops are building materials used for water stopping, made primarily of natural rubber and various synthetic rubbers, with the addition of various additives and fillers, and formed through plasticizing, mixing, and pressing.

[0003] Patent CN221021134U discloses a cutting machine for producing waterstops. When in use, rotating the rocker arm causes the threaded sleeve to move towards the center, thereby driving the rotating rod to merge towards the center and press down on the bottom plate to make the cutting blade descend, thus cutting the waterstop.

[0004] The inventors found several drawbacks in the patent during use. First, after cutting, it is necessary to manually reverse the rocker arm to raise the cutting blade to a certain height, which is cumbersome. Second, after the cutting blade contacts the waterstop, it requires considerable physical effort to rotate the rocker arm, which is laborious. Third, there is no guiding structure, making the working process unstable. The cutting blade is kept vertical solely by the weight of the rotating rod, base plate, clamping plate, and cutting blade. If the resistance between the threaded rod and threaded sleeve increases, for example, if dust enters between them, the rotating rod, base plate, clamping plate, and cutting blade will rotate along with the threaded rod when it rotates. Therefore, the working process is unstable and inconvenient to use. Furthermore, there is a risk of injury to workers if the cutting blade rotates. Fourth, there is no protective structure, making it easy for workers to come into contact with the cutting blade when laying the rubber waterstop.

[0005] Therefore, it is necessary to develop a rubber waterstop cutting machine to address the above-mentioned defects. Utility Model Content

[0006] The purpose of this utility model is to provide a rubber waterstop cutting machine that uses a telescopic cylinder as a power source. It has the advantages of simple operation, convenience, time and labor saving. The protective components can prevent workers' hands and arms from coming into contact with the blade during the laying process, thus ensuring the health of the workers.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] This utility model discloses a rubber waterstop cutting machine, including a workbench, a gantry frame fixed on the top surface of the workbench, a telescopic cylinder fixed at the top of the gantry frame, the telescopic end of the telescopic cylinder slidingly passing through the gantry frame and fixedly connected to an upper cutting blade assembly, and the upper cutting blade assembly being slidably connected to the gantry frame; protective components are installed on both sides of the upper cutting blade assembly to prevent workers from hitting the upper blade of the upper cutting blade assembly when laying the rubber waterstop; a lower cutting blade assembly is arranged on the workbench and below the upper cutting blade assembly;

[0026] The core of this utility model is to provide a rubber waterstop cutting machine, which uses a telescopic cylinder as a power source. It has the advantages of simple operation, convenience, time and labor saving. The protective components can prevent the workers' hands and arms from touching the blade during the laying process, thus ensuring the health of the workers.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. 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.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] In one specific embodiment of this utility model, a workbench 1 is included. A gantry frame 2 is fixed on the top surface of the workbench 1. A telescopic cylinder 3 is fixed at the top of the gantry frame 2. The telescopic end of the telescopic cylinder 3 slides through the gantry frame 2 and is fixedly connected to an upper cutting blade assembly. The upper cutting blade assembly is guided and slidably connected to the gantry frame 2. Protective components are installed on both sides of the upper cutting blade assembly to prevent workers from touching the upper blade 4 of the upper cutting blade assembly when laying rubber waterstops. A lower cutting blade assembly is provided on the workbench 1 and below the upper cutting blade assembly.

[0030] The workbench 1 is equipped with a temporary storage rack 13 for placing the cut rubber waterstop strips.

[0031] In use, the rubber waterstop is laid on the workbench 1. The protective components prevent workers' hands and arms from touching the upper blade 4 during the laying process. The telescopic cylinder 3 drives the upper cutting assembly to descend. The upper blade 4 and the lower cutting assembly cooperate to cut the rubber waterstop. After cutting, the telescopic cylinder 3 drives the upper cutting assembly to rise. Since the upper cutting assembly is guided and slidably connected to the gantry frame 2, the movement direction of the upper cutting assembly can be guided to prevent it from rotating arbitrarily. The telescopic cylinder 3 can be a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. This utility model uses the telescopic cylinder 3 as a power source, which has the advantages of simple and convenient operation, saving time and effort. The protective components prevent workers' hands and arms from touching the upper blade 4 during the laying process, ensuring the health of the workers.

[0032] In one specific embodiment of this utility model, the upper cutting blade assembly further includes a blade holder 5 and several guide rods 6. The top end of the blade holder 5 is fixedly connected to the telescopic end of the telescopic cylinder 3. A mounting groove is provided on one side of the bottom end of the blade holder 5, and the upper blade 4 is fixedly connected to the mounting groove. The bottom end of the upper blade 4 is lower than the bottom end of the blade holder 5. The bottom end of the guide rod 6 is fixedly connected to the blade holder 5, and the top end of the guide rod 6 slides through the gantry frame 2. When the telescopic end of the telescopic cylinder 3 drives the blade holder 5 to rise or fall, the upper blade 4 rises or falls synchronously. Through the sliding connection between the guide rod 6 and the gantry frame 2, the blade holder 5 can be guided to ensure its linear up-and-down movement and prevent it from rotating arbitrarily, thereby preventing the upper blade 4 from rotating arbitrarily and ensuring that the cut surface of the rubber waterstop is straight and not skewed.

[0033] In one specific embodiment of this utility model, the protective component includes a baffle 7, a compression spring 8, and a sliding rod 9. A baffle 7 is respectively provided on both sides of the bottom end of the blade holder 5, with the bottom end of the baffle 7 lower than the bottom end of the upper blade 4. Several sliding rods 9 are fixed to the top of the baffle 7. Ear plates corresponding to each sliding rod 9 are fixed to the side of the blade holder 5. The top end of each sliding rod 9 slides through the ear plate and is fixedly connected to a limit block 901. Compression springs 8 are correspondingly provided on each sliding rod 9, with the bottom end of the compression spring 8 abutting against the baffle 7 and the top end of the compression spring 8 abutting against the ear plate. Because the bottom end of the baffle 7 is lower than the bottom end of the upper blade 4, it can prevent the worker's hands and arms from touching the upper blade 4 during the laying process.

[0034] In one specific embodiment of this utility model, a rubber plate 10 is fixed to the bottom end of the baffle 7. During the cutting process, the telescopic end of the telescopic cylinder 3 extends and drives the blade holder 5 to descend, and the upper blade 4 descends synchronously. When the rubber plate 10 comes into contact with the rubber waterstop on the worktable 1, the telescopic end of the telescopic cylinder 3 continues to extend, the compression spring 8 is compressed, and the rubber waterstop is pressed tight, ensuring that the rubber waterstop remains flat during the cutting process and preventing it from moving, thus improving cutting accuracy. The rubber plate 10 prevents the baffle 7 from directly contacting the rubber waterstop and damaging it.

[0035] In one specific embodiment of this utility model, the lower cutting blade assembly includes a lower blade 11. A through groove is provided on the worktable 1, located between two baffles 7. The lower blade 11 is correspondingly arranged with the upper blade 4 and fixedly connected to the side wall of the through groove. The upper blade 4 and the lower blade 11 form a scissor-type cutting mechanism, which has the advantages of faster cutting speed, less blade wear, and smooth and flat cut surface compared with the cutting method of a single cutting blade.

[0036] In one specific embodiment of this utility model, a scale 12 is provided on the top surface of the workbench 1, located on the side of the discharge end of the gantry frame 2. Specifically, the zero mark of the scale 12 (not shown in the drawings) and the cutting edge of the upper blade 4 are located on the same vertical plane, facilitating the reading of cutting dimensions without the need for a measuring tape, making it simple and convenient to use. The lengths of the workbench 1 and the scale 12 can be made in different lengths according to actual needs.

[0037] In one specific embodiment of this utility model, a temporary storage rack 13 is also included. The temporary storage rack 13 includes multiple horizontal bars 1301. The top surface of the workbench 1 has guide grooves corresponding to the horizontal bars 1301. The horizontal bars 1301 are slidably connected to the guide grooves. The end of the horizontal bar 1301 away from the gantry frame 2 protrudes from the workbench 1 and is fixedly connected to a connecting rod. At least two support legs are fixed to the bottom surface of the connecting rod. In use, the temporary storage rack 13 is pulled out, allowing the horizontal bars 1301 to slide in the guide grooves and the connecting rod to move away from the workbench 1, so that the cut rubber waterstop can be placed on the horizontal bars 1301.

[0038] In one specific embodiment of this utility model, a through hole is provided on any horizontal bar 1301, and a limiting pin 14 is inserted into the through hole, with the limiting pin 14 sliding through the worktable 1. In use, the limiting pin 14 is first pulled out, and then the temporary storage rack 13 is pulled out. The setting of the limiting pin 14 can prevent the temporary storage rack 13 from sliding arbitrarily when moving the entire device.

[0039] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably, and the embodiments can be combined with each other.
