Description

Technical Field

[0001] The invention relates to the field of grinding equipment, in particular to epoxy adhesive raw material grinding equipment. Background Art

[0002] The three-roll mill grinds colloidal raw materials, such as epoxy glue and vinyl glue, by squeezing the surfaces of three horizontal rollers against each other and rubbing them at different speeds. The material is first fed into the gap between the feed roller and the middle roller. After the first grinding, it is transferred to the gap between the middle roller and the discharge roller for the second grinding, and finally scraped off the discharge roller by the blanking plate for retention.

[0003] Due to the high viscosity of epoxy glue, it flows slowly on the blanking plate. In the existing technology, the angle between the discharge plate and the tangent direction of the third roller cannot be too large to prevent the glue from being squeezed into the gap between the discharge plate and the roller instead of flowing down along the plate surface. At the same time, the discharge plate needs to extend a sufficient length to avoid the body parts, which causes the discharge plate to be mostly tilted downward at a small angle to the horizontal. When the three rollers are grinding epoxy glue with high viscosity, the glue of the third roller is intercepted by the discharge plate, and the glue cannot flow out well on the discharge plate. Manual scraping is often required to avoid too much accumulation and rebound onto the discharge roller. Summary of the Invention

DETAILED DESCRIPTION

[0026] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] Examples, such as Figures 1-8As shown: The present invention provides an epoxy adhesive raw material grinding device, which structure includes a machine body 1 with side bins 11 on both sides and a grinding roller group located on the machine body 1 and sequentially installed between the side bins 11. The grinding roller group includes a feed roller 2, an intermediate roller 3 and a discharge roller 4. The epoxy adhesive raw material enters from above the gap between the feed roller 2 and the intermediate roller 3. The rotation speed of the intermediate roller 3 is greater than that of the feed roller 2, thereby grinding and crushing the raw material. The intermediate roller 3 drives the raw material to be transported from the bottom to the discharge roller 4. The rotation speed of the discharge roller 4 is greater than that of the intermediate roller 3, further grinding and crushing the raw material. The discharge roller 4 drives the raw material to be transported out from above the discharge roller 4. The machine body 1 is provided with a blanking plate 5 on one side of the discharge roller 4. The blanking plate 5 and A cutting and conveying assembly 6 is provided between the discharge rollers 4 for intercepting the material on the discharge rollers 4 and conveying the material to the lower material plate 5. The cutting and conveying assembly 6 includes a movable roller 61. The movable roller 61 replaces the original lower material plate 5 to perform fixed scraping and interception on the raw material on the discharge roller 4, and then drives the material to be intercepted by the lower material plate 5 by rotation, so that the material can be better discharged while ensuring that the lower material plate 5 has a certain extended length. The fixed scraping can achieve the interception effect of the original discharge plate on the discharge roller 4, and the rotation is mainly for transferring the material to the lower material plate 5. Since the rotation speed of the discharge roller 4 is faster than that of the previous two roller structures, if the movable roller 61 continues to rotate to intercept the material, it is easy to cause the rotation speed to be too fast and affect the discharge;

[0028] To this end, for the structure of the moving roller 61, the moving roller 61 is provided with three corner edges 61b along the axial direction and an arc-shaped bearing surface 61a is provided between the corner edges 61b, and the center point of the arc-shaped bearing surface 61a is located on the corner edge 61b on the opposite side, that is, on the plane perpendicular to the axis of the moving roller 61, the center point of the arc of the arc-shaped bearing surface 61a between the two corner edges 61b is on the third corner edge 61b, thereby forming an arc triangle, also known as a Lelo triangle, so that the discharge roller 4 can be scraped and intercepted by a bearing surface 61a, and by setting the moving roller 61 to rotate with one of the corner edges 61b as the axis to feed the blanking plate 5, there will always be a bearing surface 61a in contact with the discharge roller 4, thereby avoiding the failure to intercept the raw material on the discharge roller 4 when the moving roller 61 transfers the raw material to the blanking plate 5.

[0029] Regarding the position of the moving roller 61, the position of the moving roller 61 includes a working position. In the working position, the corner edges 61b on both sides of the single bearing surface 61a are close to the discharge roller 4 and the blanking plate 5 respectively. The two corner edges 61b respectively fix and scrape the discharge roller 4 and connect with the blanking plate 5;

[0030] It should be noted that the inclination of the blanking plate 5 is different from the inclination of the plane where the corner edges 61b on both sides of the load-bearing surface 61a are located in the working position. Specifically, the angle between the plane of the blanking plate 5 and the horizontal plane is greater than the angle between the plane where the corner edges 61b on both sides of the load-bearing surface 61a are located in the working position and the horizontal plane. This allows the raw materials trapped on the moving roller 61 to pass through a larger inclination after being transferred to the blanking plate 5, thereby cooperating with the conveying power of the moving roller 61 to allow the materials to flow downward and be discharged better.

[0031] It should be noted that the angle between the plane where the corner edges 61b on both sides of the bearing surface 61a are located and the plane where the tangent of the contact portion between the discharge roller 4 and the corner edge 61b is located is greater than 80° and less than or equal to 90°; for the setting less than or equal to 90°: the bearing surface 61a adjacent to the bearing surface 61a on the side close to the discharge roller 4 in the working position needs to maintain contact with the discharge roller 4 in the subsequent rotation to receive new raw materials. Therefore, when the tangent angle of the contact portion between the discharge roller 4 and the corner edge 61b is 90°, the bearing surface 61a close to the discharge roller 4 needs to maintain contact with the discharge roller 4 in the subsequent rotation to receive new raw materials. The bearing surface 61a on the side near the discharge roller 4 is in a tangent state to the discharge roller 4. When it is greater than 90°, the distance between the corner edge 61b on the side near the discharge roller 4 and the discharge roller 4 will increase, thereby weakening the scraping and interception effect of the corner edge 61b on the discharge roller 4; for the setting greater than 80°: according to the properties of the arc triangle, the tangent of the bearing surface 61a in the working position at the corner edge 61b and the plane where the corner edges 61b on both sides are located have an angle of 30°, so limiting the angle to greater than 80° can ensure a better interception effect.

[0032] For the movement of the moving material roller 61, the intercepting assembly 6 also includes a side frame 62, which includes three extensions and each of which is provided with a shaft. The axes of the three shafts are respectively collinear with the three corner edges 61b. The intercepting assembly 6 also includes a rotation actuator, which is used to drive the side frame 62 and the moving material roller 61 to rotate about a single shaft. The shaft extends from the side frame 62 and is located on both sides of the side frame 62. The side bin 11 is provided with an inner limit seat 13 and an outer limit plate 14, which respectively limit the shaft on both sides of the side frame 62, thereby limiting the movement range of the shaft and the side frame 62.

[0033] As for the rotation execution part: the rotation execution part drives the shaft part on the side of the blanking plate 5 and the shaft part on the side of the discharge roller 4 after rotation to rotate in turn. To this end, the rotation execution part includes a motor-type transposition actuator 64, and the transposition actuator 64 is provided with a motor shaft 641. The motor shaft 641 is mounted on the side frame 62 as the shaft part. Two groups of clamping and positioning mechanisms 65 are also provided on the inner side of the side warehouse 11. The clamping and positioning mechanisms 65 are located on the sides of the corner edges 61b on both sides of the bearing surface 61a in the working position. A vertical portion 66 is fixed on the transposition actuator 64, and the clamping and positioning mechanism 65 includes a pair of opening and closing clamping jaws 651. The clamping jaws 651 are used to clamp the vertical portion 66 to fix the position of the transposition actuator 64. After fixing one group of transposition actuators 64, the fixed transposition actuator 64 drives the side frame 62 and the moving roller 61 to rotate, and the remaining transposition actuators 64 also rotate with the side frame 62.

[0034] In the working position, there is an angle edge 61b located below the horizontal height of the bearing surface 61a. The position of the angle edge 61b close to the blanking plate 5 is recorded as position A, the position of the angle edge 61b close to the discharge roller 4 is recorded as position B, and the position of the angle edge 61b located below the bearing surface 61a is recorded as position C. The transposition actuator 64 drives the motor shaft 641 close to position A to rotate so that position C rotates upward to the original position B. During the process, the clamping and positioning mechanism 65 of position A clamps the vertical portion 66 of position A, while the clamping and positioning mechanism 65 of position B releases the vertical portion 66 of position B. After the rotation, the transposition actuator 64 originally in position C reaches position B and drives the motor shaft 641 to rotate so that the angle edges 61b in position A and position B rotate downward. The corner edge 61b originally at position B is rotated to position A, so that the new bearing surface 61a is located at the working position. During the process, the vertical portion 66 at position B is clamped by the clamping and positioning mechanism 65, so that the side frame 62 can rotate downward, thereby completing the position change rotation of the moving roller 61. In the first rotation, the next bearing surface 61a of the moving roller 61 is kept in contact with the discharge roller 4, thereby receiving the new raw materials transferred from the discharge roller 4, avoiding the raw materials on the discharge roller 4 not being successfully intercepted when the moving roller 61 transfers the raw materials to the discharge plate 5. In the second rotation, the moving roller 61 transfers the raw materials on the first bearing surface 61a to the discharge plate 5 and pushes the materials on the discharge plate 5, so as to allow the materials to flow downward better and be discharged.

[0035] For the moving track part: the shafts on both sides of the side frame 62 are provided with tracking wheels 63, the side of the side bin 11 close to the material roller 61 is provided with an inner wall panel 12, the outer limit plate 14 is arranged on the inner side of the side bin 11, and the side frame 62 has a shaft structure connected to the material roller 61, so that the side frame 62 is located between the inner wall panel 12 and the outer limit plate 14, the inner limit seat 13 is installed on the inner wall panel 12 and the outer side is provided with an inner rail guide wall 13a, the tracking wheel 63 of the shaft on the side of the side frame 62 close to the inner wall panel 12 and the inner rail guide wall of the inner limit seat 13 13a abuts against each other, an opening is provided in the outer limit plate 14, and the inner wall of the opening is provided as an outer rail guide wall 14a. The tracking wheel 63 of the shaft portion of the side frame 62 away from the inner wall plate 12 abuts against the outer rail guide wall 14a, and the inner rail guide wall 13a is located on the inner side of the movement track of the tracking wheel 63, while the outer rail guide wall 14a is located on the outer side. As a result, the inner and outer sides of the side frame 62 are respectively restricted by the inner limit seat 13 and the outer limit plate 14, so that the side frame 62 has both space to complete multiple rotations and a track structure that can support and limit it.

[0036] It should be noted that the inner rail guide wall 13a and the outer rail guide wall 14a are both spindle-shaped, and are composed of two arc structures spliced ​​together on a plane perpendicular to the axis of the moving material roller 61. On a plane perpendicular to the axis of the moving material roller 61, the arc structure is set with the corner edge 61b on one side of the load-bearing surface 61a in the working position as the center and the maximum or minimum spacing from the corner edge 61b on one side to the tracking wheel 63 at the corner edge 61b on the other side as the radius. That is, the arc structure of the outer rail guide wall 14a is formed with the maximum spacing from the corner edge 61b on one side to the tracking wheel 63 at the corner edge 61b on the other side as the radius, and the arc structure of the inner rail guide wall 13a is formed with the minimum spacing from the corner edge 61b on one side to the tracking wheel 63 at the corner edge 61b on the other side as the radius. The two arc structures intersect with the two corner edges 61b in the working position as the center to form the spindle-shaped inner rail guide wall 13a and outer rail guide wall 14a.

[0037] In this embodiment, the non-operating transposition actuator 64 and the motor shaft 641 retain relative rotational freedom. For example, if a DC motor is used, the motor shaft 641 can rotate freely when the motor is not powered on. The clamping and positioning mechanism 65 also includes a housing 655, a motor-type worm actuator 652, and an opening and closing worm 653 mounted on the worm actuator 652. The clamping jaw 651 is rotatably mounted in the housing 655. The clamping jaw 651 is provided with a worm gear 654 that meshes with the opening and closing worm 653, thereby controlling the clamping jaw 651 to engage.

[0038] The vertical portion 66 is centered on the motor shaft 641 and is shaped in a shape with small widths at both ends and a large width in the middle, such as an ellipse, a spindle, a shuttle or an elongated rhombus. In this embodiment, an ellipse is adopted, and the inner side of the clamping claw 651 is in a shape that matches the outline of the vertical portion 66, thereby determining the specific state after clamping. A counterweight block 661 is provided on the vertical portion 66. The counterweight block 661 is installed at one end of the two small width ends of the vertical portion 66. The line connecting the counterweight block 661 and the motor shaft 641 and the line connecting the two ends of the vertical portion 66 are in the same direction as the motor shaft 641. There is an angle on the plane perpendicular to the axis 641, so that the vertical portion 66 is inclined when it droops naturally, so that the closed clamping jaws 651 can better drive the vertical portion 66 and the transposition actuator 64 to rotate after clamping the vertical portion 66. Compared with the circular structure or the gear-shaped vertical portion 66, it can better determine the position of the transposition actuator 64 and provide better clamping stability, and allow the motor shaft 641 to rotate freely, avoiding unnecessary torque between the motor shaft 641 and the transposition actuator 64 during clamping.

[0039] In summary, in a specific implementation, the epoxy adhesive raw material enters from the gap between the feed roller 2 and the intermediate roller 3, is ground by the feed roller 2, the intermediate roller 3 and the discharge roller 4, and is sent out from the top of the discharge roller 4 as the discharge roller 4 rotates. The movable roller 61 is in the working position, and the raw material rotating with the discharge roller 4 is blocked by the corner edge 61b of the movable roller 61B and is intercepted on the bearing surface 61a of the A and B positions, and gradually accumulates in the direction of the lower plate 5. After a certain amount of accumulation, the clamping and positioning mechanism 65 of the A position clamps the vertical portion 66 of the A position. , the transposition actuator 64 at position A drives the motor shaft 641 to rotate, causing position C to rotate upward to the original position of position B, and then the clamping and positioning mechanism 65 at position A is released, and the clamping and positioning mechanism 65 at position B clamps the vertical portion 66 at the current position B. The transposition actuator 64 at position B drives the motor shaft 641 to rotate, causing the corner edges 61b at position A and the original position B to rotate downward, allowing the corner edge 61b at the original position B to rotate to position A, allowing the new bearing surface 61a to be located in the working position, and the raw material on the original bearing surface 61a is also intercepted by the blanking plate 5.

[0040] As known to those skilled in the art, the transposition actuator 64 can be powered by an electric slip ring, which is installed in the side compartment 11 and is electrically connected to the transposition actuator 64 through a cable, so that the transposition actuator 64 remains electrically connected after rotation. Alternatively, this embodiment provides an implementation method in which the transposition actuator 64 is powered by a contact assembly 67, which is installed in the side compartment 11. The transposition actuator 64 is provided with a first annular contact 642 at the tail end, and the contact assembly 67 includes a second annular contact 671 installed on an elastic seat 672. The elastic seat 672 provides freedom of stretching along the axial direction, such as an elastic seat 672 with a corrugated structure of rubber material, in which the rubber provides elasticity and the corrugated structure provides space for stretching. The transposition actuator 64 is provided with a metal protrusion at the tail end. Structure, the elastic seat 672 is also provided with a magnetic positioning piece 673 for engaging and adsorbing with the raised structure. After the transposition actuator 64 on the side frame 62 is rotated to the desired position, it can be magnetically attracted by the magnetic positioning piece 673, stretching the elastic seat 672 and driving the second annular contact 671 to be magnetically attracted to the tail of the transposition actuator 64 and contact the first annular contact 642. At this time, only a conductive circuit is achieved, and the transposition actuator 64 is not powered. The power supply operation will be performed when it is needed to start. Of course, when the transposition actuator 64 is rotated and taken away by the side frame 62, the magnetic positioning piece 673 is dragged to be misplaced and thus detached. After detachment, the elastic seat 672 drives the second annular contact 671 to move outward to avoid unnecessary scratching with the rotating transposition actuator 64.

[0041] The technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
