It includes a frame and two rollers rotatably installed on the frame. The two rollers rotate towards each other and are used to extrude a rubber block placed between the two rollers. A cross bar is fixedly connected above the two rollers between the two sides of the frame. The cross bar is arranged along the axial direction of the two rollers. Two baffles that can move along it are respectively installed on the cross bar and are used to limit the extrusion width of the two rollers. The bottom edge of each baffle is in contact with the outer circumferential surfaces of the two rollers.

[0016] Beneficial effects:

[0017] (1). The high-efficiency rubber extrusion molding system adjusts the front and rear positions of the support frame through a cylinder.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] The present utility model provides two technical solutions:

[0026] Figures 1-4 The first implementation manner is shown: a high-efficiency rubber extrusion molding system, including a U-shaped workbench 1. A pressing mechanism 2 is provided at the top of the U-shaped workbench 1 for pressing a rubber block, and a limiting mechanism 3 is provided at the top of the pressing mechanism 2 for feeding the rubber block. The pressing mechanism 2 includes:

[0027] An adjusting assembly 21, the adjusting assembly 21 includes a cylinder 212 fixedly installed at the rear side near the top of the U-shaped workbench 1, and a support frame 213 is fixedly installed at the telescopic end of the cylinder 212;

[0028] A driving assembly 22, the driving assembly 22 includes a motor 221 fixedly installed at the top of the U-shaped workbench 1, a driving shaft 222 is fixedly installed at the output end of the motor 221, a cross hole 223 is opened at the rear end of the driving shaft 222, and a cross shaft 224 is slidably arranged inside the cross hole 223.

[0029] By adjusting the front and rear positions of the support frame 213 through the cylinder 212, the relative positions of the two rollers 218 are changed, thereby achieving an ideal pressing effect and ensuring the stability of the quality of the rubber product. When the positions of the two rollers 218 change, the cross shaft 224 can slide inside the cross hole 223 to avoid affecting the transmission of power when adjusting the spacing.

[0030] The adjusting assembly 21 further includes two mounting blocks 211 fixedly installed at the front side near the top of the U-shaped workbench 1. Rotating rollers 218 are rotatably arranged between the opposite side surfaces of the two mounting blocks 211 and between the inner walls of the support frame 213. Heating rods 216 for heating the rotating rollers 218 are arranged between the opposite side surfaces of the two mounting blocks 211 and between the inner walls of the support frame 213. The rotating rollers 218 are heated by the heating rods 216, and the heat is conducted to the rubber blocks, so that the rubber blocks become softer, the gas inside is more likely to escape, the air bubbles can be discharged more effectively, the quality of the rubber products is improved, and the defective rate is reduced. Scrapers 217 that fit the rotating rollers 218 are fixedly installed on the outer surfaces of the mounting blocks 211 and the support frame 213. The rubber remaining on the rotating rollers 218 can be removed in time by the scrapers 217, which helps to maintain the cleanliness of the surfaces of the rotating rollers 218, ensure their normal working state and extrusion effect, and avoid affecting the uniformity of extrusion due to the accumulation of residual rubber. Guide rods 214 are symmetrically and fixedly installed on the rear surface of the support frame 213. Limit blocks 215 are slidably arranged on the outer surfaces of the guide rods 214. The limit blocks 215 are fixedly installed on the top of the U-shaped workbench 1. First bevel gears 219 are fixedly installed at the end portions of the rotating shafts of the two rotating rollers 218. Through the sliding fit of the guide rods 214 and the limit blocks 215, the support frame 213 is guided and limited during movement, improving its stability. The drive shaft 222 is installed on the top of the U-shaped workbench 1 through a bearing seat. The rear end of the cross shaft 224 is fixedly connected to a connecting shaft 225. The connecting shaft 225 is installed on the outer surface of the support frame 213 through a bearing seat. Second bevel gears 226 that mesh with the first bevel gears 219 are fixedly sleeved on the outer surfaces of the drive shaft 222 and the connecting shaft 225.

[0031] Figures 1-4 The second implementation manner is shown. The main difference from the first implementation manner is that the limiting mechanism 3 includes a material guiding plate 31 fixedly installed on the top of the support frame 213. Mounting plates 32 are symmetrically and fixedly installed at the front side near the top of the material guiding plate 31. A cross bar 33 is fixedly connected between the opposite side outer surfaces of the two mounting plates 32. Sleeves 34 are symmetrically slidably arranged on the outer wall of the cross bar 33. Locking bolts 35 are threadedly penetrated through the outer walls of the sleeves 34. A baffle 36 is fixedly installed on the lower side of the outer wall of the sleeve 34. By sliding the sleeves 34 on the cross bar 33 to adjust the distance between the two baffles 36 and then locking with the locking bolts 35, the corresponding width of the rubber blocks can be adapted. Legs 11 are fixedly installed at the positions near the four corners of the bottom of the U-shaped workbench 1. A receiving hopper 4 is fixedly installed at the position near the middle of the bottom of the U-shaped workbench 1. A plurality of rollers 41 are rotatably arranged inside the receiving hopper 4. The rubber after extrusion directly falls into the receiving hopper 4, and through the arranged rollers 41, the rubber can roll down neatly and smoothly, avoiding the stacking phenomenon of the rubber after pressurization.

[0032] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0033] During use, the driving shaft 222 and the connecting shaft 225 are driven to rotate together by the motor 221. When the two second bevel gears 226 and the two first bevel gears 219 are engaged respectively, the two rollers 218 rotate inwards. Subsequently, the rubber block is placed between the two rollers 218 from above and is extruded and conveyed by the two rollers 218, so that the air bubbles inside the rubber block are extruded. When processing rubbers of different thicknesses, the front and rear positions of the support frame 213 are adjusted by the cylinder 212. At this time, the positions of the rollers 218 on the support frame 213 will change with the telescopic amount of the cylinder 212, while the positions of the rollers 218 on the mounting block 211 remain fixed. The positions of the two rollers 218 are adjusted appropriately according to requirements, so as to facilitate extruding rubbers of different thicknesses, achieving an ideal extrusion effect, ensuring the stability of the quality of rubber products. When the positions of the two rollers 218 change, the cross shaft 224 can slide inside the cross hole 223 to avoid affecting the power transmission when adjusting the spacing. The rubber after extrusion directly falls into the receiving hopper 4, and through the arranged rollers 41, the rubber can roll down neatly and smoothly, avoiding the stacking phenomenon of the rubber after pressurization, which is convenient for subsequent processing. The spacing between the two baffles 36 is adjusted by sliding the sleeve 34 on the cross bar 33, and then locked with the locking bolt 35, so as to adapt to rubber blocks of corresponding widths. The rollers 218 are heated by the heating rod 216, and the heat is conducted to the rubber block, so that the rubber block becomes softer, and the gas inside is more likely to escape, which can more effectively discharge the air bubbles, improve the quality of rubber products, and reduce the defective rate.
