Description

Technical Field

[0001] The utility model relates to the technical field of heating the glue application on a rubber roller, in particular to a heating device for heating the glue application on a rubber roller. Background Art

[0002] A rubber roller is a roll-shaped product made of metal or other materials as the core and rubber covered by vulcanization. It has many excellent properties, such as excellent high and low temperature resistance, excellent electrical insulation, special surface properties and physiological inertness, and high air permeability. The application range of rubber rollers is very wide, including papermaking, dyeing, printing, food processing, metallurgy, plastic processing and other industries. Rubber rollers need to be glued during the manufacturing or use process. During the gluing process, in order to make the glue liquid better and evenly coated on various materials or the surface of the rubber roller, a heating device is needed to heat the glue liquid.

[0003] Common rubber roller gluing heating devices are usually composed of structures such as heaters, heat transfer media, control systems, and roller sleeves. Turn on the device for preheating. After preheating to an appropriate temperature, start to evenly apply glue to the rubber roller. After the gluing is completed, use the drying function of the device to dry and shape the glue. This is the common structure and use of rubber roller gluing heating devices. The traditional rubber roller gluing heating device has a fixed structural position connected to the rubber roller and cannot be adjusted. The rubber rollers have different lengths due to different usage conditions, and it is impossible to connect and fix rubber rollers of different lengths before gluing. For example, patent number CN211937684U is a rubber roller gluing heating device. By opening a slide and opening multiple sets of threaded grooves at the bottom of the slide, the support plate is connected to the slider and cooperates with the first hand-tightened bolt to adjust the distance between the two sets of support plates, and can support rubber rollers of different lengths. However, in this method, in order to ensure the stability of the support plate supporting the rubber roller, the support plate and the slider need to be moved to the corresponding threaded groove on the slide groove and connected by a first hand-tightened bolt. The position of the threaded groove is fixed, resulting in the two sets of support plates being able to only support rubber rollers of appropriate lengths, and unable to support rubber rollers of different lengths within a certain range, thereby reducing the practicability of the device. For this purpose, a rubber roller gluing heating device is proposed. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a rubber roller gluing heating device to solve the above-mentioned technical problem that rubber rollers of different lengths cannot be supported within a certain range.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a rubber roller gluing heating device, comprising:

[0006] A support seat, and a connecting seat arranged at the center of the top of the support seat, wherein a clamping plate is connected to one side of the top of the connecting seat, and an extension plate is inserted in the center of the front and back sides of the support seat;

[0007] A bidirectional lead screw is arranged at the center of the front and back sides of the support seat, and sliding blocks are sleeved on both sides of the surface of the bidirectional lead screw and connected to the corresponding connecting seat. The bidirectional lead screw is composed of two sets of threaded shafts with opposite threads, and a cross groove and a cross plate are respectively opened at both ends of the threaded shaft;

[0008] The bearing seat is arranged on both sides of the front and back of the support seat and connected with the extension plate, and a second drive motor is installed on one side of the bearing seat and is coaxially connected with the bidirectional lead screw. The bidirectional lead screw is driven to rotate on the bearing seat by the second drive motor, so that the two sets of sliding blocks drive the connecting seat and the clamping plate to move towards each other, and the rubber roller can be clamped and fixed. When the length of the rubber roller exceeds the overall length of the bidirectional lead screw, the bearing seat can drive the extension plate to be pulled outward, and a threaded shaft with corresponding threads can be added, connected to the bidirectional lead screw through the cross groove and the cross plate, and then installed on the bearing seat. On the one hand, within a certain range, the clamping plate can clamp and fix rubber rollers of different lengths; on the other hand, the distance between the clamping plates can be increased, and longer rubber rollers can be clamped and fixed within a certain range, thereby improving the practicality of the device.

[0009] Preferably, a connecting ring is installed on the top of each connecting seat, and a rotating groove is opened at the center of the inner wall of each connecting ring, and the center of the connecting ring is rotatably connected to a connecting cylinder, and a first driving motor is installed on the outer side of each connecting ring and is coaxially connected to the connecting cylinder. The first driving motor drives the connecting cylinder to rotate in the connecting ring on the connecting seat.

[0010] Preferably, rotating rods are installed around the outer surface of the connecting cylinder, corresponding to the rotating grooves, and a limit rod is installed at the center of the top of the surface of the connecting cylinder, and a compression spring is installed in the inner cavity of the connecting cylinder. When the connecting cylinder rotates, the rotating rods rotate in the same direction on the rotating grooves.

[0011] Preferably, a cylindrical body is added to the outside of the connecting cylinder, and a limiting groove is provided at the corresponding position of the surface of the cylindrical body, corresponding to the limiting rod, and the inner side of the cylindrical body is connected to a clamp. The clamp is connected between the limiting groove of the cylindrical body and the limiting rod of the connecting cylinder, and the cylindrical body is driven to move outward by the extrusion spring, so that the limiting groove and the limiting rod are tightly connected. On the one hand, the stability of the clamp is ensured during operation, and separation is avoided, resulting in failure of gluing the rubber roller; on the other hand, the clamp can be replaced according to different rubber rollers, and the connecting cylinder and the cylindrical body can be disassembled and assembled by pressing and rotating, which is convenient for use.

[0012] Preferably, a guide rod is installed in the center of the inner cavity of the support seat, and reset springs are sleeved on both sides of the surface of the guide rod, and sliding plates are sleeved on both sides of the center of the surface of the guide rod, and connecting rods are installed on the front and back of the sliding plates, which extend through the inner wall of the support seat and are connected to the corresponding bearing seat. When the bearing seat moves outward, the sliding plate is driven to move on the surface of the guide rod through the corresponding connecting rod, and the corresponding reset spring is squeezed, and the reset spring applies pressure to the sliding plate in the opposite direction. On the one hand, the bearing seat is prevented from being misaligned or offset after moving outward, resulting in the inability to tilt the rubber roller and perform uniform gluing operations; on the other hand, the reset spring can make the bearing seat tightly connected to the bidirectional lead screw through the guide rod and the sliding plate, avoiding the separation and falling of multiple sets of threaded shafts.

[0013] Preferably, a top plate is installed directly above the top of the support seat, and a heating box is added at the top center of the top plate, and the liquid outlet end on the back of the heating box is connected to a pump body, and the liquid outlet end of the pump body is connected to a telescopic conduit, and a threaded screw is installed transversely at the bottom center of the top plate, and is coaxially connected to a third drive motor, and the third drive motor is located on one side of the bottom of the top plate, and a slider is sleeved on the surface center of the threaded screw, and a glue head is added at the bottom of the slider, and is connected to the telescopic conduit. After the glue liquid inside the heating box is injected into the glue head along the telescopic conduit through the pump body, the glue head sprays the glue liquid on the rubber roller for glueing, and at the same time, the third drive motor drives the threaded screw to rotate, and the slider drives the glue head to perform reciprocating translation according to the direction of the threaded screw, so as to evenly glue the rubber roller. At the same time, since the top plate and its connection structure are not directly connected to the support seat, replacement operation can be performed.

[0014] Compared with the prior art, the utility model provides a rubber roller gluing heating device, which has the following beneficial effects:

[0015] The rubber roller gluing and heating device drives the bidirectional lead screw to rotate on the bearing seat through the second driving motor, so that the two sets of sliding blocks drive the connecting seat and the clamping plate to move toward each other, and the rubber roller can be clamped and fixed. When the length of the rubber roller exceeds the overall length of the bidirectional lead screw, the bearing seat can drive the extension plate to be pulled outward, and a threaded shaft with corresponding threads can be added, connected to the bidirectional lead screw through a cross groove and a cross plate, and then installed on the bearing seat. In this way, on the one hand, within a certain range, the clamping plate can clamp and fix rubber rollers of different lengths; on the other hand, the distance between the clamping plates can be increased, and longer rubber rollers can be clamped and fixed within a certain range, thereby improving the practicality of the device.

[0025] The bearing seat 17 is arranged on both sides of the front and back of the support seat 1 and connected with the extension plate 18. A second drive motor 19 is installed on one side of the bearing seat 17 and is coaxially connected with the bidirectional lead screw 2. The bidirectional lead screw 2 is driven to rotate on the bearing seat 17 by the second drive motor 19, so that the two sets of sliding blocks drive the connecting seat 3 and the clamping plate 12 to move toward each other, and the rubber roller can be clamped and fixed. When the length of the rubber roller exceeds the overall length of the bidirectional lead screw 2, the bearing seat 17 can drive the extension plate 18 to be pulled outward, and a threaded shaft 20 with corresponding threads can be added, connected with the bidirectional lead screw 2 through the cross groove 21 and the cross plate 22, and then installed on the bearing seat 17. On the one hand, within a certain range, the clamping plate 12 can clamp and fix rubber rollers of different lengths; on the other hand, the distance between the clamping plates 12 can be increased, and longer rubber rollers can be clamped and fixed within a certain range, thereby improving the practicality of the device.

After the glue liquid inside the heating box 24 is injected into the glue head 29 along the telescopic pipe 26 through the pump body 25, the glue head 29 sprays the glue liquid on the rubber roller to perform a glue operation, and at the same time, the third drive motor 28 drives the threaded screw 27 to rotate, and the slider drives the glue head 29 to perform a reciprocating translational motion according to the direction of the threaded screw 27, so as to evenly glue the rubber roller. At the same time, since the top plate 23 and its connection structure are not directly connected to the support base 1, replacement operation can be performed.
