Description

Technical Field

[0001] The invention relates to the technical field related to rubber mixing mills, and in particular to a rubber mixing mill. Background Art

[0002] The open mixing mill is a kind of mixing plastic equipment that was used earlier by plastic product manufacturers. On the calender production line, the open mixing mill is before the calender and after the mixer. Its function is to mix and plasticize the uniformly mixed raw materials, and provide a relatively uniform molten material for the calender to calender and mold plastic products. When producing cable materials, the open mixing mill can directly mix and plasticize the powdered materials mixed according to the formula into molten materials, and then press them into sheet-like strips. In the rubber mixing process, color masterbatch is generally required to adjust the color of the rubber.

[0003] Since the amount of rubber for each rubber mixing is limited, it needs to be divided into multiple batches for rubber mixing. After the rubber mixing is completed, the operator will roll it into a roll of rubber and place it aside for standby use. After the last batch of rubber mixing is completed, the rubber will be rolled up in the form of sheets and strips and separated by plastic film to avoid sticking together. When the amount of rubber on a pair of rubber pressing rollers is insufficient, the equipment needs to be temporarily stopped to add the roll of rubber placed aside between the pair of rubber pressing rollers, and then the equipment is started to continue to output the sheet-shaped rubber. Pausing the equipment in the middle will reduce work efficiency, so it is necessary to design a rubber mixing mill. Summary of the invention

[0031] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0032] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0033] like Figure 1-8 As shown, a rubber mixing mill comprises: a mixing mill body and a feeding unit, wherein the mixing mill body comprises a base frame 1, a pair of horizontal rubber pressing rollers 2 which are arranged at a distance and rotate synchronously in opposite directions and are mounted on the base frame 1, a fixed width cutting mechanism which is mounted on the base frame 1 and can contact one of the rubber pressing rollers 2, and a pair of vertical limiting plates 3 which are both mounted on the top of the base frame 1 and can move along the length direction of the rubber pressing roller 2;

[0034] The loading unit includes a general mounting frame 4 located on the side of the base frame 1 away from the fixed-width cutting mechanism, a plurality of groups of supporting mechanisms arranged at intervals along the axial direction of the rubber pressing roller 2 for supporting the rolled rubber, a horizontal driving mechanism installed on the general mounting frame 4 for driving the plurality of groups of supporting mechanisms to move along the axial direction of the rubber pressing roller 2, a tilting driving mechanism for driving the supporting mechanism located at the unloading position to tilt, and a pushing mechanism installed on the general mounting frame 4 for pushing the rolled rubber loaded by the supporting mechanism located at the unloading position into between a pair of rubber pressing rollers 2.

[0035] In the above technical solution, the mixing mill body is an existing mature technology, so only part of the structure is shown in the figure, and its other structures and specific working principles are not described in this article.

[0036] After the fixed-width cutting mechanism is brought into contact with the corresponding rubber pressing roller 2, the rubber can be transferred to the film for subsequent processing. When the amount of rubber between the pair of rubber pressing rollers 2 is insufficient, the loading unit is started, and the horizontal driving mechanism drives several groups of supporting mechanisms to move, so that one group of supporting mechanisms is located at the unloading position, that is, the supporting mechanism located at the unloading position is located between a pair of limiting plates 3, and the tilting driving mechanism drives the supporting mechanism to tilt toward the pair of rubber pressing rollers 2, and the pushing mechanism pushes the rubber that has been refined on the supporting mechanism to between the pair of rubber pressing rollers 2 for feeding, and the feeding can be completed without stopping the machine;

[0037] After the material replenishment is completed, the inclined driving mechanism pushes the supporting mechanism to rotate and return to its original position, and the horizontal moving mechanism then drives several groups of supporting mechanisms to move, so that another group of supporting mechanisms moves to the unloading position for the next material replenishment, thereby carrying out continuous production.

[0038] In a preferred embodiment of the invention, a guide rod 5 which is parallel to the rubber pressing roller 2 and has a circular cross section is fixedly connected to the general mounting frame 4, a first sliding sleeve 6 which is slidably mounted on the guide rod 5 is fixedly mounted on the bottom of the support mechanism, and a first spacer sleeve which is slidably mounted on the guide rod 5 and has two ends respectively in contact with the corresponding first sliding sleeve 6 is provided between two adjacent first sliding sleeves 6;

[0039] The horizontal drive mechanism includes a pair of second sliding sleeves 7 fixedly connected by a connecting frame and both slidably sleeved on the guide rod 5, a first mounting frame fixedly mounted on the main mounting frame 4, a strip slide 8 arranged parallel to the guide rod 5 and mounted on the first mounting frame, a slider 9 slidably mounted on the strip slide 8 and fixedly connected to one of the second sliding sleeves 7, a threaded rod parallel to the guide rod 5 and threadedly passing through the slider 9, both ends of which are axially connected to the first mounting frame, and a motor 10 mounted on the main mounting frame 4 and having an output shaft connected to one end of the threaded rod;

[0040] A plurality of groups of supporting mechanisms are located between a pair of second sliding sleeves 7 , and a second spacer sleeve which is slidably mounted on the guide rod 5 is arranged between the first sliding sleeve 6 located at the edge and the corresponding second sliding sleeve 7 .

[0041] In the above technical solution, the first sliding sleeve 6 is sleeved on the guide rod 5. The first sliding sleeve 6 can slide on the guide rod 5 and rotate around the guide rod 5. The function of the first spacer sleeve is to fix the distance between two adjacent first sliding sleeves 6 without affecting the respective rotation of the first sliding sleeves 6. The function of the second spacer sleeve is to fix the distance between the second sliding sleeve 7 and the adjacent first sliding sleeves 6.

[0042] The motor 10 starts to drive the threaded rod to rotate, and the threaded rod drives the slider 9 to slide on the strip slide 8, and the sliding drives the two second sliding sleeves 7 to slide on the guide rod 5, thereby driving several groups of supporting mechanisms to move simultaneously.

[0043] In a preferred embodiment of the invention, a first support rod 11 and a second support rod 12 parallel to the guide rod 5 are fixedly connected to the general mounting frame 4, the first support rod 11 is located on the side of the guide rod 5 away from the rubber pressing roller 2, the second support rod 12 is located on the side of the guide rod 5 close to the rubber pressing roller 2, the middle part of the second support rod 12 is bent downward to form an avoidance space, and the bottom of the supporting mechanism is equipped with a pulley 13 matching the first support rod 11 and the second support rod 12.

[0044] In the above technical scheme, before the material supporting mechanism moves to the unloading position, the two pulleys 13 on the material supporting mechanism are in contact with the first support rod 11 and the second support rod 12 respectively, which can prevent the material supporting mechanism from tilting; when the material supporting mechanism moves to the unloading position, the tilting driving mechanism drives the material supporting mechanism to rotate, and the corresponding first sliding sleeve 6 rotates on the guide rod 5, and the end of the material supporting mechanism close to the rubber pressing roller 2 rotates downward into the avoidance space; after the rubber filling is completed, the tilting driving mechanism rotates back to its original position, and the horizontal moving mechanism pushes several groups of material supporting mechanisms to move, so that the pulley 13 separated from the second support rod 12 leaves the avoidance space and contacts the second support rod 12 again.

[0045] In a preferred embodiment of the invention, the tilting drive mechanism includes a vertical first driving push rod 14 assembled on the first mounting frame through a second mounting frame and located between the guide rod 5 and the first support rod 11, a vertical second driving push rod 15 assembled on the first mounting frame through a third mounting frame and located between the guide rod 5 and the second support rod 12, a first support member 16 fixedly mounted on the moving end of the first driving push rod 14 and capable of contacting the bottom of the supporting mechanism, and a second support member 17 fixedly mounted on the moving end of the second driving push rod 15 and capable of contacting the bottom of the pushing mechanism.

[0046] In the above technical solution, when the material supporting mechanism moves to the unloading position, the first driving push rod 14 drives the first support member 16 to move upward, and the second driving push rod 15 drives the second support member 17 to move downward. At this time, the first sliding sleeve 6 on the material supporting mechanism will rotate around the guide rod 5; after the rubber filling is completed, the second driving push rod 15 drives the second support member 17 to move upward, and the first driving push rod 14 drives the first support member 16 to move downward, driving the material supporting mechanism to rotate and return to its original position.

[0047] In a preferred embodiment of the invention, the pushing mechanism includes a third driving push rod 18 which is assembled on the main mounting frame 4 through a fourth mounting frame and whose moving end is arranged close to a pair of rubber pressing rollers 2, and a pushing plate 19 which is assembled on the moving end of the third driving push rod 18, and the moving end of the third driving push rod 18 is inclined downward.

[0048] In the above technical solution, the third driving push rod 18 drives the pushing plate 19 to move close to the rubber pressing roller 2, that is, to push the rubber on the supporting mechanism between the pair of rubber pressing rollers 2.

[0049] In a preferred embodiment of the invention, the supporting mechanism includes a base plate 20, a pair of vertical baffles 21 arranged at intervals along the length direction of the guide rod 5 and fixedly connected to the two side edges opposite to the base plate 20, a strip-shaped support plate 22 parallel to the base plate 20 and located above the base plate 20, with two long sides fixedly connected to the corresponding baffles 21, a pair of support rollers 23 arranged at intervals along the length direction of the support plate 22 and axially connected to the two baffles 21, and a smooth leather conveyor belt 24 loosely sleeved on the pair of support rollers 23, the support plate 22 is in contact with the inner top wall of the smooth leather conveyor belt 24, and the pulley 13 and the first sliding sleeve 6 are both assembled on the lower surface of the base plate 20.

[0050] In the above technical solution, since the supporting mechanism is unpowered, the smooth leather conveyor belt 24 needs to be loosely mounted on a pair of support rollers 23, otherwise the conveyor belt will not be able to slide.

[0051] Because the rubber is placed on the smooth leather conveyor belt 24, when the push plate 19 pushes the rubber, the rubber will drive the conveyor belt to move through the friction between the rubber and the smooth leather conveyor belt 24. The support plate 22 can support the smooth leather conveyor belt 24 from below to prevent the smooth leather conveyor belt 24 from being pressed downward when the rubber is placed on the smooth leather conveyor belt 24.

[0052] In a preferred embodiment of the invention, the fixed-width cutting mechanism includes a rotating shaft 25 parallel to the rubber pressing roller 2 and axially connected to the base frame 1 at both ends, a pair of cutting components symmetrically assembled on the rotating shaft 25, a worm gear 26 fixedly mounted on one end of the rotating shaft 25, a worm 27 axially connected to the base frame 1 and meshing with the worm gear 26, and a handwheel 28 assembled on one end of the worm gear 27.

[0053] In the above technical solution, the hand wheel 28 is rotated to drive the worm 27 to rotate, and then the worm gear 26 drives the rotating shaft 25 to rotate, so that a pair of cutting components can be driven to contact the corresponding rubber pressing rollers 2.

[0054] In a preferred embodiment of the invention, the rotating shaft 25 is provided with guide ridges protruding in the same length direction, and the cutting member includes a sliding arm 29 with one end slidably sleeved on the rotating shaft 25 in the same axial direction, a locking bolt 30 threadedly mounted on the sliding arm 29 and with the end thereof able to abut against the rotating shaft 25, a connecting shaft parallel to the rotating shaft 25 and axially connected to the end of the sliding arm 29 away from the rotating shaft 25, and a cutting knife 31 mounted on the connecting shaft.

[0055] In the above technical solution, by loosening the locking bolt 30, the sliding arm 29 can slide on the rotating shaft 25, thereby adjusting the position and the distance between the other group of cutting components; after the cutting knife 31 contacts the rubber pressing roller 2, the rotation of the rubber pressing roller 2 will also drive the cutting knife 31 to rotate, which can reduce the wear of the cutting knife 31 and increase its service life.

[0056] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, a variety of simple modifications can be made to the technical solution of the present invention, and these simple modifications all belong to the protection scope of the present invention.

[0057] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0058] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
