Description

Technical Field

[0001] The utility model relates to the field of insulating material preparation, in particular to an auxiliary device for preparing low-smoke flame-retardant insulating material for photovoltaic cables. Background Art

[0002] When preparing insulating materials, various raw materials must be mixed and stirred according to a specific formula ratio and then processed through steps such as hot mixing, extrusion, and pelletizing. Conventional pelletizing methods typically involve moving the insulating material through a moving structure such as a conveyor belt, passing it through a cutting device, or cutting the material as it passes through, either moving up and down or left and right. Because the insulating material is relatively soft, it easily moves when cut on a conveyor belt, resulting in errors in the cut size, waste, and reduced cutting efficiency.

[0003] Therefore, how to design a preparation auxiliary device that can solve the above technical problems is a technical problem that needs to be solved. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide an auxiliary device for preparing low-smoke flame-retardant insulation materials for photovoltaic cables, which solves the problems of insulation material movement and low pelletizing efficiency during the pelletizing process of existing pelletizing devices.

[0005] To achieve the above-mentioned object, the present invention adopts the following technical scheme: it comprises a frame, a conveyor belt installed between the frames, a cutter installed above the conveyor belt, and a feeding device installed at the front end of the conveyor belt; a plurality of cutting chambers are equidistantly provided in the cutter, a cutting device is provided in the cutting chamber, and the cutting device comprises: a moving rod, a cutting blade, a rotating shaft, and a driving motor; the cutting blade is fixedly sleeved on the outer peripheral wall of the rotating shaft, one end of the rotating shaft is connected to the output end of the driving motor, and the other end of the rotating shaft is rotatably connected to the moving rod; the inner side wall of the cutting chamber is covered with an X-axis assembly arranged along the width direction of the conveyor belt, and the end of the moving rod away from the rotating shaft is slidably connected to the X-axis assembly; the cutting blade protrudes out of the cutter bottom plate along its radial portion; a plurality of limit assemblies are fixed on the conveyor belt in parallel along its length and width directions, and the limit assemblies are at the same distance from each other, and the limit assemblies include a left limit block and a right limit block arranged opposite to each other; a groove for facilitating cutting is provided between the limit assemblies arranged adjacent to each other along the length direction of the conveyor belt.

[0006] Furthermore, a discharge port is provided at the bottom of the feeding device at a position corresponding to the limit assembly; a feed port is provided at the top of the feeding device, and a feeding channel connecting the feed port and the discharge port is provided inside the feeding device; guide rollers are provided on the side walls on both sides of the feeding channel relative to each other along the height direction thereof.

[0007] Furthermore, the left limit block and the right limit block are arranged in an eight-shaped pattern.

[0008] Furthermore, the X-axis component is a linear module or a screw rod.

[0009] Furthermore, the conveyor belt includes a horizontal conveying portion and an oblique conveying portion; the cutter and the feeding device are sequentially arranged directly above the horizontal conveying portion of the conveyor belt.

[0010] The utility model has the following beneficial effects:

[0011] 1. The utility model sets a limit assembly on the conveyor belt. When the insulating material moves to the surface of the conveyor belt through the feeding device, the insulating material falls between the left limit block and the right limit block, thereby preventing the insulating material from moving left and right when passing through the cutter, thereby improving the accuracy of insulating material cutting and improving cutting efficiency.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0021] See also Figure 1-3 As shown, the scheme includes a frame 1, a conveyor belt 2 installed between the frames 1, a cutter 3 installed above the conveyor belt 2, and a feeding device 4 installed at the front end of the conveyor belt 2;

[0022] A number of cutting cavities 31 are equidistantly provided in the cutter 3, and a cutting device is provided in the cutting cavity 31, which includes: a moving rod 311, a cutting blade 312, a rotating shaft 313 and a driving motor 314; the cutting blade 312 is fixedly sleeved on the outer peripheral wall of the rotating shaft 313, one end of the rotating shaft 313 is connected to the output end of the driving motor 314, and the other end of the rotating shaft 313 is rotatably connected to the moving rod 311, and the inner side wall of the cutting cavity 31 is covered with an X-axis assembly 315 arranged along the width direction of the conveyor belt 2, and the end of the moving rod 311 away from the rotating shaft 313 is slidably connected to the X-axis assembly 315; the cutting blade 312 protrudes from the bottom plate of the cutter 3 along its radial portion. Optimally, the width of the cutter 3 is greater than the width of the conveyor belt 2. In the initial state, the cutting blades 312 are arranged on both sides of the conveyor belt 2 and do not contact the conveyor belt 2. During the cutting process, the moving speed of the conveyor belt 2 and the movement of the cutting blades 312 are controlled according to the length of the insulating material to be pelletized. When the conveyor belt 2 stops, the cutting blades 312 are flush with the groove 22 of the conveyor belt 2, and several cutting blades 312 pass through the groove 22 on the conveyor belt 2 to cut the insulating material.

[0023] A plurality of limit assemblies 21 are fixedly provided on the conveyor belt 2 in parallel along its length and width directions, and the distances between the limit assemblies 21 are the same. The limit assemblies 21 include a left limit block 211 and a right limit block 212 arranged opposite to each other; grooves 22 for convenient cutting are provided between the limit assemblies arranged adjacent to each other along the length direction of the conveyor belt 2.

[0024] A discharge port 41 is provided at the bottom of the feeding device 4 at a position corresponding to the limit assembly 21; a feed port 42 is provided at the top of the feeding device 4, and a feed channel 43 connecting the feed port 42 and the discharge port 41 is provided inside the feeding device 4; guide rollers 431 are provided on both side walls of the feed channel 43 relative to each other along its height direction, and the insulating material is fed into the feed channel from the feed port 42, and is guided toward the discharge port 41 by the guide rollers 431 until it falls onto the conveyor belt 2.

[0025] In order to prevent the insulating material from moving left and right when the cutting blade 312 is cutting, the left limit block 211 and the right limit block 212 of this embodiment are arranged in an "eight" shape, and the insulating material is arranged between the left limit block 211 and the right limit block 212 to limit the movement of the insulating material.

[0026] Furthermore, the X-axis assembly 315 is a linear module or a lead screw.

[0027] The conveyor belt 2 includes a horizontal conveying part 23 and an oblique conveying part 24; the cutter 3 and the feeding device 4 are arranged in sequence directly above the horizontal conveying part 23 of the conveyor belt 2. After the insulating material is cut by the cutter 3, the granular insulating material passes through the oblique conveying part 24 and slides off the conveyor belt 2 and leaves the conveyor belt 2.

[0028] The working principle is roughly as follows:

[0029] The insulating material is transferred to the conveyor belt 2 through the feeding device 4. The insulating material is between the left limit block 211 and the right limit block 212. When the insulating material moves to the bottom of the cutter 3, the cutting assembly works, the drive motor 314 drives the cutting blade 312 to rotate, and the moving rod 311 drives the cutting blade 312 to reciprocate along the X-axis assembly 315 to cut the insulating material on the conveyor belt 2.
