Description

Technical Field

[0001] This utility model relates to the field of rubber raw material processing technology for conveyor belts, and in particular to a rubber cutting machine for processing rubber raw materials for conveyor belts. Background Technology

[0002] Rubber conveyor belts are crucial material handling tools in industry and logistics. They are rubber products manufactured using advanced processes and leveraging the properties of rubber. They are smooth, flexible, and elastic, wear-resistant, and adaptable to various working conditions. Used in mining for ore transport, port for cargo handling, and factory for parts delivery, their performance makes them a powerful tool for efficient production and smooth logistics across industries. In the processing of rubber raw materials for conveyor belts, rubber cutting machines are key pieces of equipment.

[0003] A rubber cutter is a rubber processing equipment that plays a unique and crucial role in both natural and synthetic rubber. Its core function is to accurately and efficiently cut large, relatively compact rubber blocks, whether they are natural rubber blocks from vast rubber forests or block rubber products synthesized through complex chemical processes, into smaller, more regular-shaped rubber blocks that are easier to process in subsequent steps, according to predetermined process standards and production requirements.

[0004] The above-mentioned technology can process natural or synthetic rubber blocks into small blocks. However, in actual use, the rubber blocks need to be accurately positioned in the cutting area of ​​the rubber cutter before cutting. If the rubber blocks are not aligned, the cutting position may shift during the cutting process, resulting in irregular shapes of the cut rubber blocks, which will affect subsequent processing and use. Therefore, a rubber cutter for processing rubber raw materials for conveyor belts is proposed to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rubber cutting machine for processing rubber raw materials for conveyor belts, comprising a working platform, characterized in that: a support frame is fixedly connected to the top of the working platform, sliding rails are provided on both sides of the support frame, blades are slidably connected inside the sliding rails, a ramp is provided at the front end of the working platform, a blade impact buffer assembly is provided at the top of the working platform, a slide rail is provided at the rear end of the working platform, a slide bar is fixedly connected to the inner wall of the slide rail, a mounting plate is fixedly connected to the top of the slide rail, a centering assembly is provided at the top of the rear end of the working platform, a slider is slidably connected inside the slide rail, sliding grooves are provided on both sides of the slider, and a clamping element is fixedly connected to the top of the slider.

[0007] As a further description of the above technical solution:

[0008] The centering assembly includes a fixed column, a rotating plate rotatably connected to the outer wall of the fixed column, a first connecting rod rotatably connected to the top rear end of the rotating plate, a second connecting rod rotatably connected to the top front end of the rotating plate, a third connecting rod rotatably connected to the top of the rotating plate, a slot is formed on the front surface of the rotating plate, a sliding column is slidably connected inside the slot, and a slide cylinder is rotatably connected to the tail end of the third connecting rod.

[0009] As a further description of the above technical solution:

[0010] The blade impact buffer assembly includes a groove, a hydraulic buffer is fixedly connected inside the groove, and a buffer plate is fixedly connected to the top of the hydraulic buffer.

[0011] As a further description of the above technical solution:

[0012] The device has two sets of slide bars, and the outer walls of both sets of slide bars are engaged with the inside of the slide groove.

[0013] As a further description of the above technical solution:

[0014] The bottom of the fixed column is fixedly connected to the inside of the slide rail.

[0015] As a further description of the above technical solution:

[0016] The bottom of the slide cylinder is fixedly connected to the inside of the slide rail.

[0017] As a further description of the above technical solution:

[0019] As a further description of the above technical solution:

[0020] The tail of the second connecting rod is rotatably connected to the bottom of the slider, and the tail of the first connecting rod is rotatably connected to the bottom of the slider.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting up a sliding cylinder, a slide rail, and a slider, the sliding cylinder is turned on and moves forward, thereby driving the third connecting rod to move and causing the rotating plate to rotate. At the same time as the rotating plate rotates, the first and second connecting rods connected to the rotating plate also rotate simultaneously. The rotation of the first and second connecting rods causes the mounting plate to slide towards the center in the slide rail to clamp the rubber raw material of the conveyor belt. This solves the problem that if the rubber block is not aligned, the cutting position may shift during the cutting process, resulting in irregular shapes of the cut rubber blocks, which affects subsequent processing and use.

[0023] 2. In this utility model, by setting a groove, a hydraulic buffer, and a buffer plate, when the blade cuts the rubber raw material of the conveyor belt, when the blade hits the buffer plate, the buffer plate slowly descends into the groove below through the action of the hydraulic buffer. When the blade disengages from the buffer plate, the spring in the hydraulic buffer resets it. This solves the problem that when the blade collides frequently with the buffer plate, the lack of an impact buffer mechanism causes the blade to become dull, reducing the cutting speed and quality, shortening the blade's service life, and increasing the cost of use.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0031] Reference Figures 1-4 This utility model provides an embodiment of a rubber cutting machine for processing rubber raw materials for conveyor belts, comprising a working platform 1. The working platform 1 is characterized by a support frame 2 fixedly connected to its top, with sliding tracks 3 on both sides of the support frame 2. Blades 4 are slidably connected inside the sliding tracks 3. When the blades 4 impact a buffer plate 63, the buffer plate 63 slowly descends into a lower groove 61 under the action of a hydraulic buffer 62. When the blades 4 disengage from the buffer plate 63, a spring within the hydraulic buffer 62 resets them. This solves the problem of blade dulling due to the lack of an impact buffer mechanism when the blades 4 frequently collide with the buffer plate 63, reducing cutting speed and quality, and shortening the service life of the blades 4. To reduce operating costs, the working platform 1 has a ramp 5 at its front end, which facilitates the automatic downward sliding and collection of small rubber blocks processed from the conveyor belt. The top of the working platform 1 is equipped with a blade impact buffer assembly 6, and the tail of the working platform 1 is equipped with a slide rail 9. A slide bar 10 is fixedly connected to the inner wall of the slide rail 9, and a mounting plate 8 is fixedly connected to the top of the slide rail 9. The mounting plate 8 provides support for the rubber raw materials of the conveyor belt during cutting. The top of the tail of the working platform 1 is equipped with a centering assembly 7, and two sliders 11 are slidably connected inside the slide rail 9. The sliders 11 are distributed in two sets in the slide rail 9, and the sides of the sliders 11 are provided with grooves 12. A clamping element 13 is fixedly connected to the top of the sliders 11.

[0032] Reference Figures 1-4The centering component 7 includes a fixed column 71, with a rotating plate 72 rotatably connected to the outer wall of the fixed column 71. A first connecting rod 73 is rotatably connected to the top rear end of the rotating plate 72. When the first connecting rod 73 moves backward, a second connecting rod 74 moves forward. The rotation of the first and second connecting rods 73 and 74 causes the mounting plate 8 to slide towards the center in the slide rail 9, clamping the rubber raw material of the conveyor belt. This solves the problem of misalignment of the rubber blocks, which may cause cutting position deviation during the cutting process, resulting in irregular shapes of the cut rubber blocks and affecting subsequent processing and use. A second connecting rod 74 is rotatably connected to the top front end of the rotating plate 72, and a third connecting rod 75 is rotatably connected to the top of the rotating plate 72. A groove 77 is opened on the front surface of the rotating plate 72, and a sliding column 78 is slidably connected inside the groove 77. A slide cylinder 76 is rotatably connected to the tail end of the third connecting rod 75. Opening the slide cylinder 76 activates the slide... The cylinder 76 moves forward, thereby driving the third connecting rod 75 to move, causing the rotating plate 72 connected to the fixed column 71 to rotate. Simultaneously, the first connecting rod 73 and the second connecting rod 74 connected to the rotating plate 72 also rotate. The blade impact buffer assembly 6 includes a groove 61, inside which a hydraulic buffer 62 is fixedly connected. The hydraulic buffer 62 uses hydraulic damping to buffer and decelerate the object acting upon it to a stop, effectively preventing damage to the mechanism caused by hard collisions. A buffer plate 63 is fixedly connected to the top of the hydraulic buffer 62, which has two sets of slide bars 10. The outer walls of both sets of slide bars 10 are engaged inside the slide groove 12. The bottom of the fixed column 71 is fixedly connected to the inside of the slide rail 9, and the bottom of the slide cylinder 76 is fixedly connected to the inside of the slide rail 9. The main components of the slide cylinder 76 include the cylinder body, working piston, guide column, and clamping mechanism. The cylinder body is typically made of corrosion-resistant materials such as aluminum alloy, and contains a working piston with inlet and outlet ports. The piston is driven by compressed air to achieve linear or rotary motion. The inner part of the third connecting rod 75 is rotatably connected to the top outer wall of the sliding column 78, the tail of the second connecting rod 74 is rotatably connected to the bottom of the slider 11, and the tail of the first connecting rod 73 is rotatably connected to the bottom of the slider 11.

[0033] Working principle: During use, the slide cylinder 76 is activated, causing it to move forward. This moves the third connecting rod 75, causing the rotating plate 72, connected to the fixed column 71, to rotate. Simultaneously, the first connecting rod 73 and the second connecting rod 74 connected to the rotating plate 72 also rotate. The first connecting rod 73 moves backward, and the second connecting rod 74 moves forward. This rotation causes the mounting plate 8 to slide towards the center in the slide rail 9, clamping the rubber material of the conveyor belt and preventing misalignment of the rubber blocks during cutting. Positional misalignment leads to irregular shapes of the cut rubber blocks, affecting subsequent processing and use. When the blade 4 cuts the rubber raw material on the conveyor belt, the blade 4 impacts the buffer plate 63. Under the action of the hydraulic buffer 62, the buffer plate 63 slowly descends into the groove 61 below. When the blade 4 disengages from the buffer plate 63, the spring inside the hydraulic buffer 62 resets it. This solves the problem that when the blade 4 frequently collides with the buffer plate 63, the lack of an impact buffer mechanism causes the blade to become dull, reducing the cutting speed and quality, shortening the service life of the blade 4, and increasing the cost of use.
