[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0024] like Figure 1-3 As shown, an EVA brick drilling device is mainly used for drilling holes in EVA material bricks, such as yoga bricks or some children's brick toys, which can be turned into brick building blocks after drilling. It includes a hollow cabinet 1, with a feeding mechanism 3 and a corresponding cylinder c13 on both sides of the cabinet 1. The cylinder c13 faces the feeding mechanism 3 and can fix the brick from the front; that is, after the brick is fed out of the feeding mechanism 3, the cylinder c13 extends and directly abuts against the brick from the front to achieve a fixing effect. A screw 10 is provided on the parallel side of the cylinder c13, and a support frame 4 is sleeved on the screw 10. A drilling mechanism 6 is provided on the support frame 4. Specifically, the support frame 4 is sleeved on the screw 10 and can move on the screw, while the drilling mechanism 6 is fixed on the support frame 4.

[0025] The support frame 4 consists of a horizontal base and a vertical plate perpendicular to the horizontal base; ball nuts 4.1 are respectively provided at both ends of the horizontal base for fitting onto the screw 10 so that the support frame 4 can move back and forth on the screw; two parallel guide rails 12 are symmetrically arranged on the vertical plate, and a sliding plate 11 that can move up and down along the guide rail 12 is provided on the guide rail 12.

[0026] The drilling mechanism 6 includes a shaft 6.1 and a bushing 6.4 sleeved on the shaft 6.1. A pulley a6.2 is sleeved on the upper end of the shaft 6.1, and a drilling tool 16 is provided at the lower end. A fixing cover 6.3 is provided on the outer ring of the bushing 6.4 to fix the drilling mechanism 6 on the sliding plate 11.

[0027] A punching mechanism 6 is fixed on one side of the sliding plate 11, and a motor a7 is fixed on the other side. A pulley b7.1 is sleeved on the upper end of the motor a7. In other words, the motor a7 is used to provide power to the punching mechanism 6.

[0028] A belt 20 is fitted onto the pulleys a6.2 and b7.1. Specifically, the motor a7 drives the pulley a6.2 to rotate via the belt 20. The pulley a6.2 is fitted onto the shaft 6.1. When the pulley a6.2 is driven to rotate, the shaft 6.1 rotates accordingly. The cutter 16 located at the end of the shaft 6.1 will rotate together. With the support frame 4 moving up and down on the guide rail 12, the cutter 16 enters the brick vertically, thus realizing the drilling operation.

[0029] A protruding fixing post 11.1 is provided in the middle of the sliding plate 11.

[0030] The top of the support frame 4 is provided with a cylinder b5, and a collar 5.1 is provided at the end of the cylinder b5; furthermore, the collar 5.1 is fitted onto the fixed column 11.1, thus connecting the cylinder b5 to the sliding plate 11, and the cylinder b5 can drive the sliding plate 11 to move up and down on the guide rail 12.

[0031] The feeding mechanism 3 includes a base plate 3.2, and a pad 3.1 below the base plate 3.2 so that one end of the base plate 3.2 is higher than the other end. On both sides of the base plate 3.2, there are feeding plates 3.5 to form a material cavity for placing bricks. A discharge hole 3.4 is provided at the bottom of the feeding plate 3.5 near the drilling mechanism 6 for feeding out bricks.

[0032] A cylinder a2 is provided on the outer side of the feeding mechanism 3; specifically, the piston rod of the cylinder a2 passes through the discharge plate 3.5 and extends into the material cavity; specifically, first, all the bricks that need to be drilled are put into the material cavity, and then the cylinder a2 is activated to push the bottom brick to the discharge hole 3.4. Since one end of the bottom plate 3.2 is inclined, after the cylinder a2 applies an external force to the brick, under the action of gravity, the brick will automatically continue to fall down and reach the preset point, i.e., the surface of the cabinet 1.

[0033] A cylinder a2 is installed on one side of the cabinet 1, and a cylinder c13 is installed on the corresponding position on the other side. An opening is made at one end of the cabinet 1 near the cylinder c13, allowing the front of this part of the cabinet 1 to communicate with the hollow inner cavity. A material drop plate 19 inclined downward to the bottom is provided at this opening end of the cabinet 1. Specifically, after the brick is drilled, the cylinder a2 pushes another brick to be processed to the preset position. At this time, because the brick to be processed is pushed out, it will collide with the processed brick, thus pushing the processed brick to fall into the opening of the cabinet 1, and then fall down along the material drop plate 19.

[0034] A fixing frame 14 is provided between the cabinet 1 and the cylinder c13, and a stop block a13.1 is provided at the end of the cylinder c13 for the piston rod of the cylinder c13 to extend out and stop the brick from one end.

[0035] An opening 18 is provided in the center of the front of the cabinet 1 for the waste material to fall off during drilling. Specifically, the cabinet 1 is a hollow structure. On the working surface of the front, a large square opening is provided at the end near the cylinder c13, thus forming an area that is completely connected to the hollow interior. Between this square opening and the discharge hole 3.4, or more precisely at the preset position for brick processing, an opening 18 is also provided on the front. In this way, the waste material cut out during the drilling process will fall directly into the cabinet 1 through the opening 18.

[0036] A cylinder d15 is provided on one side of the cabinet 1, perpendicular to the cylinder c13, and a stop block b15.1 is provided at the end of the cylinder d15. Specifically, the cylinder d15 is used to fix the brick from one side. Because the cylinder d15 is perpendicular to the cylinder c13, when the cylinders d15 and c13 work simultaneously to fix the brick in two directions, the position of the brick can be fixed, preventing it from shifting during drilling and ensuring drilling accuracy.

[0037] On the front of the cabinet 1 near the screw on the side of the opening 18, there is a stop bar 17 for limiting the brick. That is, when the cylinder d15 pushes the brick from the other side to fix the side of the brick, the stop bar 17 is the limiting and fixing point of the other side of the brick. Once the brick is pushed to the stop bar 17 by the cylinder d15, it will be limited. This, together with the cylinder c13, can fix the three sides of the brick. In particular, the stop bar 17 and the cylinder d15 completely clamp and fix the two sides of the brick.

[0038] Support blocks 9 are provided at both ends of the screw 10 for supporting the screw. A motor b8 is provided at the end of the screw 10 near the cylinder c13 for driving the screw 10. A guide plate 21 is provided below the screw 10 for guiding the movement of the support frame 4. Furthermore, the support plate 4 is sleeved on the screw 10 by ball nuts 4.1. When the screw 10 rotates, the ball nuts 4.1 will move on the screw 10, thereby driving the movement of the support frame 4. The support frame 4 is locked on the guide plate 21, which ensures that the movement direction of the support frame 4 will not deviate.

[0039] It should be noted that the "ends" in cylinders a2, b5, c13, and d15 of this application, which are described as having components such as abutments and collars at their ends, all refer to the ends of the piston rods in the cylinders. Since this is prior art and common knowledge, the applicant will not describe it in detail.

[0040] The beneficial effects of this utility model are:

[0041] Targeting the characteristics of EVA material bricks, multiple cylinders are used to achieve automatic material feeding and fixing, improving work efficiency; and a combination of screw and drilling mechanism is used to create a simple and movable mechanism, which is not only simple in structure and low in cost, but also enables automated drilling, and the drilling is precise and convenient.
