Description

Technical Field

[0001] The invention relates to the technical field of rubber supply for rubber mixing, and in particular to a rubber supply device for mixing rubber. Background Art

[0002] During the production process, rubber materials must go through multiple processing steps to produce rubber products that meet composite requirements, and the rubber mixing process is an extremely important process. The main purpose of rubber mixing is to ensure that various compounding agents are evenly dispersed in the raw rubber, so as to obtain rubber with uniform physical and mechanical properties to meet the subsequent process operations and finished product quality requirements.

[0003] Rubber mixing equipment is mainly divided into open mixers and internal mixers. Among them, open mixers are more flexible and suitable for handling small batch and multi-variety rubber mixing production. Therefore, they are widely used in small and medium-sized rubber product manufacturers.

[0004] When the rubber mixing mill is mixing rubber, the rubber material and various compounding agents are repeatedly squeezed through the squeezing rollers so that the compounding agents are evenly dispersed in the rubber material. Therefore, the staff is required to continuously pull up one end of the rubber material that has passed through the gap between the squeezing rollers and then re-feed it into the feed end of the gap between the squeezing rollers so that the rubber material is squeezed and mixed by the squeezing rollers again. At the same time, in order to improve the mixing effect, the staff is required to continuously roll and fold the rubber material from the side to the middle position of the rubber material to enhance the uniformity of the dispersion of the compounding agents. In this process, the staff needs to continuously lift and fold the rubber material to complete the rubber supply operation of the mixed rubber, which is extremely physically demanding and there is a risk that the palm may be caught in the gap between the squeezing rollers. In order to solve the above problems, a mixed rubber supply device is urgently needed. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a rubber mixing supply device, which solves the problem that when the existing rubber mixing mill is mixing rubber, workers need to manually lift and fold the rubber to complete the rubber mixing operation, which is extremely labor-intensive for the workers and easily results in the risk of the palm being caught in the gap between the extrusion rollers.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A mixed rubber supply device comprises a base,

[0008] Two first vertical plates are symmetrically fixedly connected to the top of the base, two squeezing rollers are symmetrically rotated front and back between the two first vertical plates, two second vertical plates are symmetrically fixedly connected to the top of the two first vertical plates, two conveying rollers are symmetrically rotated up and down between the two second vertical plates, a flanging assembly is provided on the top of the base, a folding assembly is connected to the flanging assembly, and both the flanging assembly and the folding assembly are located on the front side of the first vertical plate;

[0009] The flanging assembly is used to flanging the left and right sides of the mixed sheet rubber material toward the center and upper side;

[0010] The folding assembly is used to fold the edge of the film turned up by the flanging assembly in a direction overlapping and parallel to the film.

[0011] Preferably, the flanging assembly includes two first fixed plates symmetrically connected to the top of the base, two pairs of first electric push rods are symmetrically fixedly inserted on the sides away from each other of the two first fixed plates, two first flanging blocks are symmetrically fixedly connected to the output ends of the two first electric push rods, and two first inclined surfaces are symmetrically provided on the sides close to each other of the two first flanging blocks. Under the action of the first inclined surfaces, the thickness of the sides close to each other of the two first flanging blocks gradually increases from bottom to top. The advantage of such a setting is that when the two pairs of first electric push rods are started, they respectively push the two first flanging blocks to move in the direction of approaching each other, and make the film conveyed by the conveying roller and the squeezing roller slide through the front of the two first inclined surfaces. In this way, under the limiting guidance of the two first inclined surfaces, the left and right edges of the film can be flipped forward, thereby realizing automatic flipping of the film edge, and there is no need for the staff to manually flip up the film edge, which saves the staff's physical strength and avoids the staff's hands from being caught in the gap between the two squeezing rollers, thereby improving the safety and practicality of the glue supply device.

[0012] Preferably, the flanging assembly also includes two pairs of second electric push rods symmetrically fixedly inserted on the sides away from the two first fixed plates, and two second flanging blocks are symmetrically fixedly connected between the output ends of the two pairs of second electric push rods, and two second inclined surfaces are symmetrically provided on the sides close to each other of the two second flanging blocks. Under the action of the second inclined surfaces, the thickness of the sides close to each other of the two second flanging blocks gradually increases from bottom to top, and the two second flanging blocks are respectively located on the lower sides of the two first flanging blocks, and the sides close to each other of the two second flanging blocks are respectively located on the left and right sides of the sides close to each other of the two first flanging blocks. The advantage of such an arrangement is that the edge of the film can be flipped forward slightly by the two first flanging blocks first, and then the two second flanging blocks located above can flip the edge of the clip forward more significantly on the basis of the flanging of the first flanging blocks, so that the edge of the film is gradually flipped forward from small to large, avoiding excessive flipping that causes film breakage or hinders the normal movement and mixing of the film, ensuring that the glue supply operation can be carried out smoothly, and effectively improving the reliability of the glue supply device.

[0013] Preferably, the folding assembly includes two mounting blocks symmetrically fixedly sleeved between the output ends of the second electric push rods, the front faces of the two mounting blocks are symmetrically connected to two fixed frames, the side walls of the two fixed frames that are close to each other are of a through-type design, the sides of the two fixed frames that are far away from each other are symmetrically fixedly connected to two pairs of third electric push rods, the output ends of the two pairs of third electric push rods pass through the side walls of the two fixed frames and are symmetrically fixedly connected to two folding plates, the two folding plates are respectively located in front of the two pairs of second electric push rods and respectively located on the front sides of the two second flange blocks. The advantage of such an arrangement is that starting the two pairs of third electric push rods pushes the two folding plates toward the adjacent sides, so that the edge of the film flipped forward by the first flange block and the second flange block can be pushed in a direction parallel to the middle part of the film, so that the edge of the film is completely folded over, thereby improving the uniformity of dispersion of the compounding agent in the rubber material during the mixing process, and improving the reliability and practicality of the glue supply device.

[0014] Preferably, the folding assembly also includes two groups of round rods symmetrically fixedly connected on the adjacent sides of the two folding plates, and each group of multiple round rods is equidistantly distributed from top to bottom. Two groups of balls are symmetrically rotatably sleeved on the adjacent ends of the two groups of round rods. The advantage of such an arrangement is that the balls rotate around the round rods, so that the balls are tightly against the edge of the film and in the process of folding the edge of the film over, there is rolling friction between the balls and the edge of the film, thereby ensuring that the film can be transported and mixed more smoothly and stably, further improving the reliability and practicality of the glue supply device.

[0015] Preferably, the two mounting blocks are connected with an angle adjustment component, which is used to drive the two fixed frames to swing back and forth to adjust the angle between the folding plate and the vertical surface. The advantage of such a setting is that the angle between the folding plate and the vertical surface can be adjusted according to the film of different thicknesses, so that the folding component can reliably fold the film of different thicknesses, ensuring that the glue supply work can be carried out smoothly, thereby improving the reliability of the glue supply device.

[0016] Preferably, a folding assembly is provided on the two folding plates, and the folding assembly is used to press the edge of the film folded over by the ball against the middle part of the film. The advantage of such a setting is that it can ensure that the edge of the film folded over is pressed tightly against the middle part of the film, thereby ensuring that the edge of the film folded over will not flip back before entering the gap between the two extrusion rollers, thereby ensuring that the glue supply work is carried out reliably and smoothly.

[0017] Preferably, the folding assembly includes two installation cavities symmetrically opened on the front sides of the two folding plates, two connecting plates are symmetrically fixedly connected on the inner walls of the two installation cavities that are close to each other, two groups of fourth electric push rods are symmetrically fixedly connected on the sides of the two connecting plates that are far away from each other, and two groups of pressure blocks are symmetrically fixedly connected on the output ends of the two groups of fourth electric push rods, and the axis lines of the fourth electric push rods and the length directions of the folding plates where they are located are not parallel to each other. The advantage of such a configuration is that the two groups of fourth electric push rods can be started to reciprocate and extend to push the two groups of pressure blocks to reciprocate and hit the edge of the film, so that they can hit the edge of the film to press the edge of the film tightly against the middle position of the film, ensuring that the folding operation of the film is carried out stably and reliably, greatly improving the reliability and practicality of the glue supply device.

[0018] Preferably, the folding assembly also includes a accommodating chamber opened on the sides away from each other of the two groups of pressing blocks, two groups of first motors are symmetrically fixedly connected to the tops of the two groups of pressing blocks, two groups of first rotating rods are symmetrically rotatably connected between the inner top wall and the inner bottom wall of the two groups of accommodating chambers, the top ends of the two groups of first rotating rods pass through the inner top wall of the accommodating chamber and are respectively fixedly connected to the output ends of the two groups of first motors, and threaded feeding rollers are fixedly sleeved on the outer circumferential surfaces of the two groups of first rotating rods. The advantage of such an arrangement is that when the first motor is started to drive the threaded feeding roller to rotate, the threaded feeding roller can drive the film to move upward toward the conveying roller while pressing the edge of the film tightly against the middle part of the film, thereby ensuring continuous folding operation on the edge of the film without hindering the normal movement of the film, thereby improving the quality and reliability of the folding of the edge of the film, and avoiding to the greatest extent the edge of the film from folding back in the opposite direction before entering the gap between the two squeezing rollers, thereby greatly improving the glue supply reliability of the glue supply device.

[0019] Preferably, a left-right movable component is provided on the base, and the left-right movable component includes two rectangular plates symmetrically fixedly connected to the top of the base, a bidirectional screw is rotatably connected between the adjacent sides of the two rectangular plates, a guide rod is fixedly connected between the adjacent sides of the two rectangular plates, a second motor is fixedly connected to the left side surface of the rectangular plate on the left, the output end of the second motor passes through the left rectangular plate and is fixedly connected to the left end of the bidirectional screw, two support plates are symmetrically threadedly sleeved on the external thread surface of the bidirectional screw, the two support plates are symmetrically and movably sleeved on the outer peripheral surface of the guide rod, and the two first fixed plates are symmetrically fixedly connected to the top of the two support plates. The advantage of such a setting is that the spacing between the two first flange blocks and the two second flange blocks can be flexibly adjusted according to the width of the film, thereby expanding the application scope of the glue supply component.

[0020] In summary, the present invention mainly has the following beneficial effects:

[0021] 1. By setting two conveying rollers located above the squeezing roller, the cooperation of the squeezing roller and the conveying roller can make the film pass through the gap between the two squeezing rollers continuously, ensuring that the film mixing work is carried out automatically and continuously, and there is no need for the staff to manually feed one end of the film into the gap between the two squeezing rollers. At the same time, the flanging assembly and the folding assembly cooperate with each other to automatically complete the folding operation of the left and right edges of the film, and there is no need for the staff to manually flip and fold the edges of the film, which greatly reduces the labor intensity of the staff, avoids the staff's hands from being caught in the gap between the two squeezing roller brackets, and improves the practicality and safety of the glue supply device.

[0022] 2. The folding assembly can ensure that the folded edge of the film is pressed tightly against the middle part of the film, thereby ensuring that the folded edge of the film will not flip back before entering the gap between the two squeezing rollers, ensuring that the glue supply work is carried out reliably and smoothly.

[0037] The flanging assembly 4 is used to flanging the left and right sides of the mixed sheet rubber material toward the center and upper side;

[0038] The folding assembly 5 is used to fold the edge of the film turned up by the flanging assembly 4 in a direction overlapping and parallel to the film.

Under the action of the first inclined surfaces, the thickness of the sides close to each other of the two first flanging blocks 43 gradually increases from bottom to top.

[0040] Specifically, the two pairs of first electric push rods 42 are started to push the two first flange blocks 43 towards each other, and the film transported by the conveying roller 31 and the squeezing roller 21 slides through the front of the two first inclined surfaces. In this way, under the limiting guidance of the two first inclined surfaces, the left and right edges of the film can be flipped forward, thereby realizing automatic flipping of the film edges. There is no need for the staff to manually flip up the film edges, which saves the staff's physical strength and avoids the staff's hands being caught in the gap between the two squeezing rollers 21, thereby improving the safety and practicality of the glue supply device.

Under the action of the second inclined surfaces, the thickness of the sides close to each other of the two second flanging blocks 45 gradually increases from bottom to top. The two second flanging blocks 45 are respectively located on the lower sides of the two first flanging blocks 43, and the sides close to each other of the two second flanging blocks 45 are respectively located on the left and right sides of the sides close to the two first flanging blocks 43.

[0042] Specifically, the two first flange blocks 43 can first slightly flip the edge of the film forward, and then the two second flange blocks 45 located above can flip the edge of the clip forward to a greater extent based on the flanging of the first flange blocks 43. In this way, the edge of the film is gradually flipped forward from small to large, avoiding excessive flipping that may cause the film to break or hinder the normal movement and mixing of the film, ensuring that the glue supply operation can be carried out smoothly, and effectively improving the reliability of the glue supply device.

[0045] See also Figure 5-Figure 8 The folding assembly 5 also includes two groups of round rods 55 symmetrically fixedly connected to the adjacent sides of the two folding plates 54. Each group of multiple round rods 55 are evenly distributed from top to bottom, and two groups of balls 56 are symmetrically rotatably sleeved on the adjacent ends of the two groups of round rods 55.

[0046] Specifically, the ball 56 rotates around the round rod 55 so that the ball 56 is pressed against the edge of the film and the edge of the film is folded over. There is rolling friction between the ball 56 and the edge of the film, thereby ensuring that the film can be transported and mixed more smoothly and stably, further improving the reliability and practicality of the glue supply device.

[0047] participate Figure 4-Figure 8 , the two mounting blocks 51 are connected with an angle adjustment assembly 7, and the angle adjustment assembly 7 is used to drive the two fixing frames 52 to swing back and forth to adjust the angle between the hemming plate 54 and the vertical surface;

[0050] See also Figure 5-Figure 8 A folding assembly 8 is provided on the two folding plates 54, and the folding assembly 8 is used to press the edge of the film folded over by the ball 56 onto the middle part of the film.

[0051] Specifically, it can ensure that the folded edge of the film is pressed tightly against the middle part of the film, thereby ensuring that the folded edge of the film will not flip back before entering the gap between the two squeezing rollers 21, ensuring reliable and smooth glue supply.

[0053] Specifically, the two groups of fourth electric push rods 83 are started to reciprocate and extend to push the two groups of pressing blocks 84 to reciprocate and hit the edge of the film, thereby hitting the edge of the film to press the edge of the film tightly to the middle position of the film, ensuring that the folding operation of the film is carried out stably and reliably, greatly improving the reliability and practicality of the glue supply device.

[0054] See also Figure 4-Figure 9 The folding assembly 8 also includes a accommodating cavity opened on the side away from the two groups of pressing blocks 84, and two groups of first motors 85 are symmetrically fixedly connected to the top of the two groups of pressing blocks 84. Two groups of first rotating rods are symmetrically rotatably connected between the inner top wall and the inner bottom wall of the two groups of accommodating cavities. The top ends of the two groups of first rotating rods pass through the inner top wall of the accommodating cavity and are respectively fixedly connected to the output ends of the two groups of first motors 85, and threaded feeding rollers 86 are fixedly sleeved on the outer circumferential surfaces of the two groups of first rotating rods.

[0055] Specifically, the first motor 85 is started to drive the threaded feed roller 86 to rotate, so that the threaded feed roller 86 can press the edge of the film tightly against the middle part of the film, and at the same time, the threaded feed roller 86 can drive the film to move upward toward the conveying roller 31, thereby ensuring continuous folding of the edge of the film without hindering the normal movement of the film, improving the quality and reliability of folding the edge of the film, and avoiding to the greatest extent the edge of the film from folding back in the opposite direction before entering the gap between the two squeezing rollers 21, thereby greatly improving the glue supply reliability of the glue supply device.

[0056] See also Figure 1-Figure 3 A left-right moving component 6 is provided on the base 1, and the left-right moving component 6 includes two rectangular plates 62 symmetrically fixedly connected to the top of the base 1, a bidirectional screw 63 is rotatably connected between the adjacent sides of the two rectangular plates 62, a guide rod 64 is fixedly connected between the adjacent sides of the two rectangular plates 62, a second motor 65 is fixedly connected to the left side surface of the rectangular plate 62 on the left, an output end of the second motor 65 passes through the left rectangular plate 62 and is fixedly connected to the left end of the bidirectional screw 63, two support plates 61 are symmetrically threadedly sleeved on the external thread surface of the bidirectional screw 63, the two support plates 61 are symmetrically and movably sleeved on the outer peripheral surface of the guide rod 64, and the two first fixed plates 41 are symmetrically fixedly connected to the top of the two support plates 61.

[0057] Specifically, the distance between the two first flange blocks 43 and the two second flange blocks 45 can be flexibly adjusted according to the width of the film, thereby expanding the application scope of the glue supply component.

[0058] Working principle: The rubber compound is put into the gap between two squeezing rollers 21, and the two squeezing rollers 21 extrude and mix the rubber compound. Then the compounding agent is put into the rubber compound. As the squeezing rollers 21 continuously extrude and mix the rubber compound, the compounding agent is evenly dispersed in the rubber compound.

[0059] After the rubber material is extruded and mixed into a sheet, the staff pulls up one end of the film through the gap between the two squeezing rollers 21 and passes through the front sides of the two first inclined surfaces and the front sides of the two second inclined surfaces, then passes through the gap between the two conveying rollers 31, and then inserts it into the gap between the two squeezing rollers 21 again, so that the film is formed into a ring and circulates under the conveyance of the squeezing rollers 21 and the conveying rollers 31. In this way, the staff does not need to manually insert one end of the film into the gap between the two squeezing rollers 21 continuously, thereby realizing automatic glue supply operation and reducing the labor intensity of the staff.

[0060] Then, the two pairs of first electric push rods 42 are started to push the two first flanging blocks 43 towards each other, and the film conveyed by the conveying roller 31 and the squeezing roller 21 slides through the front of the two first inclined surfaces. In this way, under the limiting guidance of the two first inclined surfaces, the left and right edges of the film can be flipped forward, thereby realizing the automatic flipping of the film edges.

[0061] And with the cooperation of the first flange block 43 and the second flange block 45, the two first flange blocks 43 can first slightly flip the edge of the film forward, and then the two second flange blocks 45 located above can flip the edge of the clip forward to a greater extent based on the flanging of the first flange blocks 43. In this way, the edge of the film is gradually flipped forward from small to large, avoiding excessive flipping that may cause the film to break or hinder the normal movement and mixing of the film, ensuring that the glue supply operation can be carried out smoothly, and effectively improving the reliability of the glue supply device.

[0062] At the same time, two pairs of third electric push rods 53 are started to push the two folding plates 54 toward the adjacent sides, so that the edge of the film flipped forward by the first flanging block 43 and the second flanging block 45 can be pushed in a direction parallel to the middle part of the film, so that the edge of the film is completely folded over, thereby improving the uniformity of the compounding agent dispersed in the rubber material during the mixing process, and improving the reliability and practicality of the glue supply device.

[0063] Then, the two groups of fourth electric push rods 83 are started to push the two groups of threaded feed rollers 86 tightly against the edge of the film, and then the first motor 85 is started to drive the threaded feed rollers 86 to rotate, so that the threaded feed rollers 86 can press the edge of the film tightly against the middle part of the film while driving the film to move upward toward the conveying roller 31, thereby ensuring continuous folding of the edge of the film without hindering the normal movement of the film, improving the quality and reliability of the folding of the edge of the film, and avoiding to the greatest extent the edge of the film from folding back in the opposite direction before entering the gap between the two squeezing rollers 21, thereby greatly improving the glue supply reliability of the glue supply device.
