Description

Technical Field

[0001] This utility model belongs to the technical field of rubber production equipment, and specifically relates to a slicing device for rubber. Background Technology

[0002] Rubber slicing refers to the process of processing natural or synthetic rubber (such as styrene-butadiene rubber, chloroprene rubber, silicone rubber, etc.) into sheet materials of specific thickness, shape, and size using slicing equipment. The sliced ​​rubber sheets can be used directly for subsequent processing (such as molding, vulcanization, bonding, etc.) or as semi-finished products for the production of various rubber products.

[0003] Currently, rubber processing employs an assembly line operation model. After pretreatment, the rubber raw material is placed on a conveyor belt and sent to a slicing device. The slicing device slices the rubber by reciprocating the movement of a cutter. However, the lack of fixation during slicing can lead to skewed cuts, and the shifting of the rubber raw material results in uneven slices, affecting subsequent processing. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the above shortcomings, the present utility model provides a slicing device for rubber, which further improves the quality of rubber slices.

[0005] Technical solution: In order to achieve the above objectives, the present invention provides a slicing device for rubber, including a cutting component and a housing component, wherein the cutting component is disposed at one end of the housing component; The cutting assembly includes a mounting frame, an upper cutter, and a lower cutter. The mounting frame is mounted on the chassis assembly. The upper cutter is fixed on an upper cutter fixing plate. Both ends of the upper cutter fixing plate are slidably mounted on the mounting frame via a set of sliding plates. The lower cutter is fixed on a lower cutter fixing plate, which is mounted on the mounting frame. The slide plate is equipped with a top blade cylinder bracket, the top blade cylinder bracket is equipped with a top blade cylinder, and the piston rod of the top blade cylinder is connected to the back of the upper cutting blade fixing plate; It also includes a clamping assembly, which includes a set of sliders, a cylinder, a set of mounting rods and a clamping block. The sliders are slidably mounted on the mounting frame via a linear guide rail. The cylinders are mounted on the mounting frame and connected to the sliders. One end of the mounting rods is mounted on the sliders and the other end is connected to the clamping block.

[0006] Furthermore, the slide plate is slidably mounted on the mounting frame via a set of linear guide rails. The mounting frame is equipped with a set of cutting and lifting cylinders, which are connected to the slide plate. An upper cutting blade connecting block is mounted on the slide plate and is fixed to an upper cutting blade fixing plate. The cutting and lifting cylinders drive the slide plate to move, thereby causing the upper cutting blade to move up and down reciprocally to complete the cutting action.

[0007] Furthermore, the chassis assembly includes a set of symmetrically arranged chassis, on which the cutting component is mounted. The chassis assembly also includes a front feeding roller and a rear feeding roller, respectively located on the side of the chassis furthest from and closest to the cutting component. Both the front and rear feeding rollers are covered with anti-slip rubber sleeves and have coaxially mounted rotary encoders. Rubber is fed to the cutting component via the front and rear feeding rollers. The anti-slip rubber sleeves on the feeding rollers increase the friction between the rollers and the rubber to prevent slippage. The length of the material being fed can be calculated using the rotary encoder.

[0008] Furthermore, a feeding support plate is provided between the front feeding roller and the rear feeding roller, and transition rollers are provided on both sides of the feeding support plate.

[0009] Furthermore, the chassis is also equipped with guide rollers, which are located at the front end of the front feeding roller.

[0010] Furthermore, the machine housing is equipped with a tension roller mechanism, which includes a set of tensioning rotating rods rotatably mounted on the machine housing and a tension roller mounted on the tensioning rotating rods. The tension roller is connected to the tensioning rotating rods via a set of connecting rods. One end of the tensioning rotating rods is connected to an adjusting cylinder, which is located inside the machine housing. The tension roller is used to adjust the tension between the rubber and the feeding roller. The adjusting cylinder drives the tensioning rotating rods, thereby rotating the tension roller and adjusting the tension.

[0011] Furthermore, a cross-cutting mesh support plate is provided between the rear feeding roller and the cutting assembly. The cross-cutting mesh support plate is mounted on the machine casing, and an anti-static air bar is located below the cross-cutting mesh support plate, with both ends of the anti-static air bar mounted on the machine casing. The cross-cutting mesh support plate provides support for the rubber before it enters the cutting position, and the anti-static air bar can promptly neutralize the static electricity on the surface of the rubber slice, ensuring the quality of the slices. Furthermore, a receiving assembly is connected to the side of the chassis assembly near the cutting assembly. The receiving assembly includes a material rack and a receiving plate. The receiving plate is mounted on the material rack and is inclined, with a baffle plate on its surface. The bottom of the material rack is equipped with casters with brakes. After the rubber is cut, it is collected on the receiving plate, and the material rack with casters can drive the receiving plate to complete the transfer.

[0012] As can be seen from the above technical solution, this utility model has the following beneficial effects: 1. This utility model provides a rubber slicing device with a simple structure and reasonable design. A pressing block is set at the cutting position to press down the rubber to prevent the rubber from shifting during cutting. At the same time, a top cylinder is set to prevent the upper cutter from shifting due to long-term force, which would affect the cutting accuracy. Automatic feeding is completed by a set of feeding rollers, and fixed-length cutting can be achieved by a rotary encoder.

[0013] 2. This utility model is equipped with an anti-static fan at the cutting position, which can neutralize the static electricity on the surface of the rubber slice in time and ensure the quality of the slice; a material collection component is set at the rear end of the cutting component, which can collect the rubber slices efficiently and orderly.

Detailed Implementation

[0016] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0017] like Figure 1-3 As shown: A slicing device for rubber includes a cutting component 1 and a housing component 2, wherein the cutting component 1 is disposed at one end of the housing component 2; The cutting assembly 1 includes a mounting frame 11, an upper cutter 12, and a lower cutter 13. The mounting frame 11 is mounted on the chassis assembly 2. The upper cutter 12 is fixed on the upper cutter fixing plate 14. Both ends of the upper cutter fixing plate 14 are slidably mounted on the mounting frame 11 via a set of sliding plates 16. The lower cutter 13 is fixed on the lower cutter fixing plate 15. The lower cutter fixing plate 15 is mounted on the mounting frame 11. like Figure 5 As shown, the slide plate 16 is provided with a top knife cylinder bracket 161, and the top knife cylinder bracket 161 is provided with a top knife cylinder 162. The piston rod of the top knife cylinder 162 is connected to the back of the upper cutting blade fixing plate 14. The top knife cylinder 162 acts on the upper cutting blade fixing plate 15 to prevent the upper cutting blade fixing plate 14 from fatigue and shifting during long-term movement, which would affect the cutting accuracy. It also includes a clamping assembly 3, which comprises a set of sliders 31, a cylinder 32, a set of mounting rods 33, and a clamping block 34. The sliders 31 are slidably mounted on the mounting frame 11 via a linear guide rail. The cylinder 32 is mounted on the mounting frame 11 and connected to the sliders 31. One end of the mounting rod 33 is mounted on the sliders 31, and the other end is connected to the clamping block 34. During cutting, the cylinder 32 presses the clamping block 34 down onto the rubber to prevent the rubber from moving during cutting.

[0018] like Figure 4 As shown, the slide plate 16 is slidably mounted on the mounting frame 11 via a set of linear guide rails. The mounting frame 11 is provided with a set of cutting lifting cylinders 17, which are connected to the slide plate 16. The slide plate 16 is provided with an upper cutting blade connecting block 163, which is fixed to the upper cutting blade fixing plate 14.

[0019] The chassis assembly 2 includes a set of symmetrically arranged chassis, on which the cutting assembly 1 is mounted. The chassis assembly 2 also includes a front feeding roller 21 and a rear feeding roller 22, located on opposite sides of the chassis away from and closer to the cutting assembly 1, respectively. Both the front and rear feeding rollers are covered with anti-slip rubber sleeves and have coaxially mounted rotary encoders. Rubber is conveyed via the front and rear feeding rollers 21 and 22. The feeding length can be calculated using the rotary encoders on the front and rear feeding rollers 21 and 22, enabling fixed-length cutting. Both the front and rear feeding rollers 21 and 22 are upper and lower pressure rollers, which can flatten the rubber before cutting. Furthermore, an internal cooling system can be installed inside the front feeding roller 21 to rapidly cool the rubber and improve cutting quality.

[0020] Specifically, a feeding plate 23 is provided between the front feeding roller 21 and the rear feeding roller 22, and transition rollers 24 are provided on both sides of the feeding plate 23.

[0021] Specifically, the chassis is also equipped with a guide roller 25, which is located at the front end of the front feeding roller 21.

[0022] like Figure 1 and Figure 6 The machine casing is equipped with a tension roller mechanism, which includes a set of tensioning rotating rods 26 rotatably mounted on the machine casing and a tension roller 27 mounted on the tensioning rotating rods 26. The tension roller 27 is connected to the tensioning rotating rods 26 via a set of connecting rods. One end of the tensioning rotating rods 26 is connected to an adjusting cylinder 28, which is located inside the machine casing. The extension and retraction of the piston rod of the adjusting cylinder 28 can drive the tensioning rotating rods 26 to rotate, thereby causing the tension roller 27 to rotate around the tensioning rotating rods 26, thus adjusting the rubber tension and achieving more precise slicing.

[0023] like Figure 7 As shown, a cross-cutting mesh support plate 29 is provided between the rear feeding roller 22 and the cutting assembly 1. The cross-cutting mesh support plate 29 is mounted on the machine casing, and an anti-static air bar 291 is provided below the cross-cutting mesh support plate 29, with both ends of the anti-static air bar 291 mounted on the machine casing. During the rubber slicing process, static electricity is easily generated due to friction between the rubber and the cutting tool, leading to problems such as slice adhesion and dust adsorption. The anti-static air bar is installed near the cutting tool to neutralize the static electricity on the surface of the rubber slices in a timely manner, ensuring the quality of the slices.

[0024] Preferably, the housing assembly 2 is connected to a receiving assembly on the side near the cutting assembly 1. The receiving assembly includes a material rack 41 and a receiving plate 42. The receiving plate 42 is disposed on the material rack 41. The receiving plate 42 is inclined and has a baffle plate on its surface. The bottom of the material rack 41 is provided with universal wheels with brakes.

[0025] The working principle of a rubber slicing device in this embodiment is as follows: The rubber sequentially passes through guide roller 25, tension roller 27, front feeding roller 21, transition roller 24, and rear feeding roller 22, reaching the cutting position of the cutting assembly. The operator pre-sets the cutting length. After the rotary encoder rotates to the set value, the front feeding roller 21 and rear feeding roller 22 stop feeding, and at the same time, the clamping block 34 moves down to press the rubber. The upper cutter 12 moves downward under the drive of the cutting lifting cylinder 17, cooperating with the lower cutter 13 to cut the rubber. The cut rubber sheet slides onto the receiving plate 42, completing the sequential slicing action, and this process is repeated.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
