Description

Technical Field

[0001] This utility model relates to the field of strip cutting machine technology, specifically a strip cutting machine for processing rubber anti-collision strips. Background Technology

[0002] In the rubber product processing industry, rubber bumper strips are core protective components in automobiles, furniture, and machinery, and their width specifications need to be precisely adapted to the application scenario. The strip cutting machine, as a key piece of equipment in rubber bumper strip processing, uses multiple sets of cutting blades to divide continuous rubber rolls into strips of a set width. "Blade spacing adjustment" is the core factor determining the strip specifications; the spacing accuracy directly affects the assembly adaptability of the bumper strip, while also meeting the need for rapid switching between multiple specification orders.

[0003] Based on the above, the inventors have discovered the following problems: Existing rubber anti-collision strip processing cutting machines have significant defects in the spacing adjustment process. The tool spacing adjustment relies on the rigid fixing of bolts and manual disassembly and positioning, which is cumbersome and time-consuming, and cannot meet the needs of "multiple batches, small batches, and fast switching" in modern production.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a strip cutting machine for processing rubber anti-collision strips, in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this utility model is to provide a cutting machine for processing rubber anti-collision strips, so as to solve the problem mentioned in the background art that the existing cutting machines for processing rubber anti-collision strips have significant defects in the spacing adjustment process.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A rubber anti-collision strip cutting machine includes a main body and an adjustment mechanism. The main body includes a base, a placement frame is installed on one side of the upper end of the base, and a winding frame is installed on the other side of the upper end of the base. The adjustment mechanism includes an adjustment frame, the bottom end of which is connected to the center of the upper end of the base. A pair of sliding rods are fixedly installed at both the upper and lower ends inside the adjustment frame. A plurality of first and second sliding blocks are slidably installed between each pair of sliding rods. A first mounting seat and a second mounting seat are fixedly installed on the facing surfaces of the first and second sliding blocks, respectively. A first spline sleeve is rotatably connected inside the first mounting seat, and a second spline sleeve is rotatably connected inside each of the second mounting seats. A cutter is fitted on the upper part of each of the first spline sleeves, and an extrusion plate is fitted on the upper part of each of the second spline sleeves. The cutter and the extrusion plate correspond one-to-one.

[0008] Furthermore, the upper and lower ends of the adjustment frame are rotatably connected to rollers between each pair of slide rods, and the two ends of the rollers are provided with several arc-shaped grooves.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the arc groove of the roller provides a guide trajectory for the ball, and rotating the roller can simultaneously drive multiple first and second sliders to move, ensuring that the spacing between the cutter and the extrusion plate is adjusted in a consistent manner, and avoiding uneven strip width caused by unilateral offset.

[0010] Furthermore, ball bearings are fixedly installed at the opposite ends of the first and second sliders, and the ball bearings are slidably connected to the arc-shaped grooves at their corresponding positions.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the rolling cooperation between the ball and the arc groove converts the sliding friction when the slider moves into rolling friction, reduces the adjustment resistance, makes the adjustment of the distance between the cutter and the extrusion plate smoother, and reduces the wear of the parts.

[0012] Furthermore, the first spline sleeve and several second spline sleeves are all splinedly connected by ball splines, and the two ends of the ball splines are respectively rotatably connected to the inner sides of the adjusting frame.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the ball spline is splined with the first spline sleeve and the second spline sleeve, which not only transmits rotational power to drive the cutter and extrusion disc to rotate, but also allows the slider to move along the spline axis, so that power transmission and spacing adjustment do not interfere with each other, resulting in a compact structure and efficient transmission.

[0014] Furthermore, a first transmission box is fixedly installed on one side of the adjustment frame, and a pair of sprockets are rotatably connected inside the first transmission box, and the pair of sprockets are connected by chain drive.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the sprocket and chain in the first transmission box cooperate to realize the synchronous rotation of the two rollers, ensure the coordinated adjustment of the upper and lower sliders, ensure the precise correspondence between the cutter and the extrusion plate, and improve the consistency of adjustment.

[0016] Furthermore, a first servo motor is fixedly installed on one side of the first transmission box, and the output end of the first servo motor is connected to one of the sprockets.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the first servo motor provides stable power for the rotation of the roller, the output speed is precise and controllable, and the slider movement distance can be precisely adjusted according to the strip width requirements, thereby improving the accuracy and convenience of spacing adjustment.

[0018] Furthermore, a second transmission box is fixedly installed on the other side of the adjustment frame. A pair of gears are rotatably connected to the inner side of the second transmission box. One side of the central shaft of the pair of gears is connected to one end of the pair of ball splines, and the pair of gears mesh with each other.

[0019] The beneficial effect of adopting the above-mentioned further solution is that a pair of gears mesh with each other, realizing the synchronous rotation of two ball splines in opposite directions, driving the corresponding cutter and extrusion disc to rotate in opposite directions, enhancing the pressing and cutting effect on the rubber strip, and ensuring processing stability.

[0020] Furthermore, a second servo motor is fixedly installed on one side of the second transmission box, and the output end of the second servo motor is connected to one of the gears.

[0021] The beneficial effect of adopting the above-mentioned further solution is that the second servo motor provides power to the ball spline, drives the cutter and extrusion disc to rotate at high speed and stably, and the speed can be controlled to adapt to rubber materials of different hardness, thereby improving the cutting efficiency and cut smoothness.

[0022] Furthermore, guide frames are fixedly installed on both sides of the upper end surface of the base, which is located on both sides of the adjustment frame.

[0023] The beneficial effect of adopting the above-mentioned further solution is that the guide frame limits the feeding and discharging direction of the rubber anti-collision strip, avoids the rubber strip from deviating or wrinkling, ensures the smooth conveying of the rubber strip during the cutting process, and further improves the cutting accuracy.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows: The rubber anti-collision strip processing cutting machine uses a main body placement frame and a winding frame to realize the unwinding and winding of the rubber anti-collision strip. In the adjustment mechanism, the first slider and the second slider move along the slide rod, driving the cutter and the extrusion plate to adjust the distance, adapting to the cutting requirements of different widths. The cutter and the extrusion plate correspond one-to-one, so that when the rubber raw material passes through the extrusion plate and the cutter, the extrusion plate works with the cutter to cut, ensuring the strip is flat and improving processing accuracy and efficiency. The arc groove of the roller provides a guide track for the ball bearings. Rotating the roller can simultaneously drive multiple first sliders and second sliders to move, ensuring that the distance between the cutter and the extrusion plate is adjusted consistently, avoiding uneven strip width caused by unilateral offset.

[0032] 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.

[0033] Please see Figure 1 - Figure 6This utility model provides a technical solution: a rubber anti-collision strip cutting machine, including a main body 1 and an adjustment mechanism 2. The main body 1 includes a base 101, a placement frame 102 is installed on one side of the upper end of the base 101, and a winding frame 103 is installed on the other side of the upper end of the base 101. The adjustment mechanism 2 includes an adjustment frame 201, the bottom end of which is connected to the center of the upper end of the base 101. A pair of sliding rods 206 are fixedly installed at both the upper and lower ends inside the adjustment frame 201, and each pair of sliding rods 206 slides between them. The device is equipped with several first sliders 207 and second sliders 210. The opposing surfaces of the first sliders 207 and second sliders 210 are respectively fixedly mounted with first mounting bases 208 and second mounting bases 211. The first mounting base 208 is rotatably connected to a first spline sleeve 217. The second mounting base 211 is rotatably connected to a second spline sleeve 218. Each first spline sleeve 217 is fitted with a cutter 209. Each second spline sleeve 218 is fitted with an extrusion plate 212. The cutter 209 and the extrusion plate 212 correspond one-to-one.

[0034] As an embodiment of this utility model, further, the upper and lower ends of the adjustment frame 201 are rotatably connected to rollers 213 between each pair of slide rods 206. Several arc-shaped grooves 214 are mirrored at both ends of the rollers 213. The arc-shaped grooves 214 of the rollers 213 provide a guide track for the balls 219. Rotating the rollers 213 can synchronously drive multiple first sliders 207 and second sliders 210 to move, ensuring that the spacing between the cutter 209 and the extrusion plate 212 is consistent, and avoiding uneven strip width caused by unilateral offset.

[0035] As an embodiment of this utility model, the opposite ends of the first slider 207 and the second slider 210 are both fixedly installed with ball bearings 219. The ball bearings 219 are slidably connected to the arc grooves 214 at their corresponding positions. The ball bearings 219 and the arc grooves 214 roll together, converting the sliding friction when the slider moves into rolling friction, reducing the adjustment resistance, making the adjustment of the distance between the cutter 209 and the extrusion plate 212 smoother, and reducing component wear.

[0036] As an embodiment of this utility model, the first spline sleeve 217 and several second spline sleeves 218 are all splinedly connected by ball splines 220. The two ends of the ball splines 220 are rotatably connected to the inner sides of the adjusting frame 201 respectively. The ball splines 220 are splinedly connected to the first spline sleeve 217 and the second spline sleeves 218, which not only transmits rotational power to drive the cutter 209 and the extrusion plate 212 to rotate, but also allows the slider to move along the spline axis, so that the power transmission and spacing adjustment do not interfere with each other, and the structure is compact and the transmission is efficient.

[0037] As an embodiment of this utility model, a first transmission box 203 is fixedly installed on one side of the adjustment frame 201. A pair of sprockets 215 are rotatably connected inside the first transmission box 203. The pair of sprockets 215 are connected by a chain drive. The sprockets 215 in the first transmission box 203 cooperate with the chain to realize the synchronous rotation of the two rollers 213, ensuring the coordinated adjustment of the upper and lower sliders, ensuring the accurate correspondence between the cutter 209 and the extrusion plate 212, and improving the consistency of adjustment.

[0038] As an embodiment of this utility model, a first servo motor 204 is fixedly installed on one side of the first transmission box 203. The output end of the first servo motor 204 is connected to one of the sprockets 215. The first servo motor 204 provides stable power for the rotation of the roller 213. The output speed is precise and controllable. The slider movement distance can be precisely adjusted according to the strip width requirement, thereby improving the accuracy and convenience of spacing adjustment.

[0039] As an embodiment of this utility model, a second transmission box 202 is fixedly installed on the other side of the adjusting frame 201. A pair of gears 216 are rotatably connected to the inner side of the second transmission box 202. The central shaft of one side of the pair of gears 216 is connected to one end of a pair of ball splines 220. The pair of gears 216 mesh with each other, so that the two ball splines 220 rotate synchronously in opposite directions, driving the corresponding cutter 209 and extrusion disc 212 to rotate in opposite directions, thereby enhancing the pressing and cutting effect on the rubber strip and ensuring processing stability.

[0040] As an embodiment of this utility model, a second servo motor 205 is fixedly installed on one side of the second transmission box 202. The output end of the second servo motor 205 is connected to one of the gears 216. The second servo motor 205 provides power to the ball spline 220, driving the cutter 209 and the extrusion disc 212 to rotate at high speed and stably. The rotation speed is controllable to adapt to rubber materials of different hardness, thereby improving the cutting efficiency and the flatness of the cut.

[0041] As an embodiment of this utility model, further, guide frames 104 are fixedly installed on both sides of the upper end surface of the base 101 and the adjustment frame 201. The guide frames 104 limit the feeding and discharging direction of the rubber anti-collision strip to avoid the rubber strip from shifting or wrinkling, ensuring that the rubber strip is transported smoothly during the cutting process and further improving the cutting accuracy.

[0042] Specifically, the working principle of this rubber anti-collision strip processing cutting machine is as follows: During use, based on the required cutting width, the first servo motor 204 is started to drive the sprocket 215 and chain drive in the first transmission box 203, causing the two rollers 213 in the adjusting frame 201 to rotate synchronously. The arc-shaped groove 214 of the rollers 213 pushes the first slider 207 and the second slider 210 to move synchronously along the slide rod 206 via the ball bearings 219, adjusting the distance between the cutter 209 and the extrusion disc 212. Then, the second servo motor 205 is started, driving the gears 216 meshing within the second transmission box 202. The two ball splines 220 are driven to rotate synchronously in opposite directions. The ball splines 220 drive the cutter 209 and the extrusion plate 212 to rotate in opposite directions through the first spline sleeve 217 and the second spline sleeve 218, respectively. The rubber raw material roll is placed on the placement rack 102. The raw material is pulled through the guide frame 104 on one side and then passes between the extrusion plate 212 and the cutter 209 in the corresponding group. The extrusion plate 212 works with the cutter 209 to cut it precisely. The cut rubber strip is guided by the guide frame 104 on the other side and then wound up by the winding frame 103. The whole process realizes the automated and precise cutting of the rubber anti-collision strip.

[0043] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, this application will not explain the control method and circuit connection in detail.
