Description

Technical Field

[0001] The utility model relates to the technical field of rubber processing equipment, in particular to an automatic feeding device for a vulcanizer. Background Technique

[0002] A vulcanizer is a machine for vulcanizing various rubber and plastic products, with functions such as timing mold clamping, automatic pressure compensation, automatic temperature control, automatic timing, and alarm when the time is up. Vulcanizers can be divided into three forms: electric heating, steam heating, and heat-conducting oil heating. It is also called a flat vulcanizer, a foam board vulcanizer, and a rubber vulcanizer.

[0003] In the Chinese utility model patent with the publication number of CN217414618U, a rapid feeding device for a flat vulcanizer is disclosed. This device pre-arranges multiple groups of raw materials inside the first through hole before feeding, so that when feeding, only by controlling the first driving component and the second driving component, multiple groups of raw materials can be quickly stacked on the vulcanizing plate at one time, changing the traditional manual feeding method of stacking raw materials on the vulcanizing plate one by one, improving the production efficiency. The inventor believes there are the following defects:

[0004] When this device is actually used, although it is faster than the manual stacking method, the rubber raw materials still need to be filled manually. Moreover, due to the lack of an integrated structure that can automatically fill materials in the device, the loading process is not only troublesome but also increases the consumption of human resources. Therefore, we provide an automatic feeding device for a vulcanizer. Content of the Utility Model

[0005] To solve the problem in the above background technique that it is difficult for the device to automatically fill materials, resulting in a troublesome loading process and an increase in the consumption of human resources, the utility model provides an automatic feeding device for a vulcanizer.

[0006] The utility model is realized by adopting the following technical solutions: an automatic feeding device for a vulcanizer, comprising:

[0007] A processing table, the processing table is in a return shape structure, and brackets are symmetrically and fixedly connected to the top thereof. The center of the top of the bracket is fixedly connected with an electric push rod, and the telescopic end of the electric push rod is fixedly connected with a connecting plate. The bottom of the connecting plate is equidistantly and fixedly connected with pressing blocks through connecting columns;

[0008] A lead screw, the lead screw is symmetrically and rotatably connected to the top of the processing table. One end of the lead screw is coaxially fixedly connected with a motor. An upper feeding plate is arranged above the processing table. Both sides of the bottom of the upper feeding plate are symmetrically and fixedly connected with connecting blocks, and the connecting blocks are in threaded connection with the lead screw on the same side. The surface of the upper feeding plate is equidistantly provided with receiving grooves penetrating through the upper feeding plate;

[0009] Automatic filling assembly, the automatic filling assembly includes a feeding hopper fixedly connected above the processing table through a connecting frame, a rotating shaft is rotatably connected inside the feeding hopper, stirring rods are fixedly connected circumferentially at equal intervals on the outer part of the rotating shaft, a gear is coaxially fixedly connected at one end of the rotating shaft, and a toothed plate is fixedly connected to one side of the top of the feeding plate and meshes with the gear;

[0010] Automatic discharging assembly, the automatic discharging assembly includes a baffle plate, discharging grooves penetrating through the baffle plate are equidistantly arranged on the surface of the baffle plate, sliding blocks are symmetrically fixedly connected to both sides of the baffle plate, sliding rods are fixedly connected to both sides of the feeding plate and are slidably connected with the sliding blocks, and springs are sleeved on the outer parts of the sliding rods.

[0011] As a further improvement of the above solution, the automatic discharging assembly further includes:

[0012] Magnet block 1, magnet block 1 is symmetrically fixedly connected to both sides of the baffle plate, and magnet block 2 is fixedly connected to both sides of the top of the processing table through connecting seats.

[0013] As a further improvement of the above solution, the centers of magnet block 1 and magnet block 2 are on the same horizontal line, and the magnetic pole directions of the opposite faces of magnet block 1 and magnet block 2 are set in opposite directions.

[0014] As a further improvement of the above solution, receiving plates are fixedly connected to both sides of the bottom of the processing table.

[0015] As a further improvement of the above solution, blocking plates are fixedly connected to both sides of the feeding plate.

[0016] As a further improvement of the above solution, the size of the receiving groove is consistent with the size of the discharging groove.

[0017] As a further improvement of the above solution, the bottom of the discharging port of the feeding hopper is in contact with the surface of the feeding plate, and the bottom of the feeding plate is in contact with the top of the baffle plate.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] 1. The utility model drives a lead screw to rotate through a motor, so as to drive a feeding plate to move horizontally. During the movement of the feeding plate, when the accommodating groove communicates with the feeding hopper, the rubber particle raw materials inside the feeding hopper will automatically enter the accommodating groove, thus achieving the purpose of automatic feeding. And during the movement of the feeding plate, the toothed plate can also be driven to move together. By using the meshing effect between the toothed plate and the gear, the rotation shaft can be driven to rotate. The rotation of the rotation shaft drives the stirring rod to rotate, and the stirring rod can stir the rubber particles, thereby preventing blockage caused by excessive friction between the rubber particles and between the rubber particles and the inner wall of the feeding hopper. It has strong practicability, ensures the smoothness of feeding, and effectively avoids the problem that the device is difficult to automatically fill materials, making the loading process not only troublesome but also increasing the consumption of human resources.

[0020] 2. When driving the raw materials to move after vulcanization is completed, due to the mutual adsorption effect between the first magnet block and the second magnet block, the feeding plate will move forward alone first. When the accommodating groove communicates with the discharging groove, the rubber inside the accommodating groove will automatically fall out, thus achieving the purpose of automatic discharging, further improving the practicability of the device, avoiding the time spent on separately controlling the discharging during the processing process, improving the processing efficiency. At the same time, by using the sliding fit between the slider and the sliding rod, when the feeding plate moves, the slider will stretch or compress the spring. When the end of the sliding rod contacts the slider, at this time the feeding plate will drive the baffle plate to move together. When the first magnet block and the second magnet block are separated, due to the elastic return of the spring, the baffle plate will automatically reset, thus facilitating the normal use of the subsequent device.

[0027] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0028] Embodiment 1:

[0029] Please combine Figures 1-4 , an automatic feeding device for a vulcanizing machine of this embodiment comprises:

[0030] The processing table 1 is a U-shaped structure and a bracket is symmetrically fixedly connected to the top of the processing table 1. The electric push rod 2 is fixedly connected to the center of the top of the bracket. The telescopic end of the electric push rod 2 is fixedly connected to a connecting plate 3. The bottom of the connecting plate 3 is equidistantly fixedly connected to a pressure block 4 through a connecting column. The bottom of the processing table 1 is fixedly connected to receiving plates 9 on both sides to facilitate receiving and collecting the fallen rubber;

[0031] The screw rod 5 is symmetrically rotatably connected to the top of the processing table 1, one end of the screw rod 5 is coaxially fixedly connected to the motor, and a loading plate 6 is arranged above the processing table 1. The bottom sides of the loading plate 6 are symmetrically fixedly connected with connecting blocks 7, and the connecting blocks 7 are threadedly connected to the screw rod 5 on the same side. The surface of the loading plate 6 is equidistantly provided with receiving grooves 8 that penetrate the loading plate 6;

[0032] An automatic filling assembly, which includes a hopper 101 fixedly connected to the processing table 1 through a connecting frame, a rotating shaft 102 is rotatably connected inside the hopper 101, a stirring rod 103 is fixedly connected to the outside of the rotating shaft 102 at equal intervals, a gear 104 is coaxially fixedly connected to one end of the rotating shaft 102, a toothed plate 105 is fixedly connected to one side of the top of the feeding plate 6 and meshed with the gear 104, and blocking plates 106 are fixedly connected to both sides of the feeding plate 6 to prevent the rubber particles inside the hopper 101 from leaking out during processing;

[0033] Automatic discharging assembly. The automatic discharging assembly includes a material baffle 201. The surface of the material baffle 201 is equidistantly provided with blanking grooves 202 penetrating through the material baffle 201. Both sides of the material baffle 201 are symmetrically and fixedly connected with sliding blocks 203. Both sides of the feeding plate 6 are fixedly connected with sliding rods 204 and are slidably connected with the sliding blocks 203. A spring 205 is sleeved on the outside of the sliding rod 204.

[0034] The automatic discharging assembly further includes:

[0035] A first magnet block 206, which is symmetrically and fixedly connected to both sides of the material baffle 201. Both sides of the top of the processing table 1 are fixedly connected with a second magnet block 207 through connecting seats. The centers of the first magnet block 206 and the second magnet block 207 are on the same horizontal line. The magnetic pole directions of the opposite faces of the first magnet block 206 and the second magnet block 207 are set in opposite directions, which is convenient for the first magnet block 206 and the second magnet block 207 to adsorb together when approaching and contacting. The bottom of the discharge port of the feeding hopper 101 is in contact with the surface of the feeding plate 6, and the bottom of the feeding plate 6 is in contact with the top of the material baffle 201, further preventing the leakage of rubber particles.

[0036] In the embodiment of the present application, the implementation principle of an automatic feeding device for a vulcanizer is as follows: First, rubber particles are added into the feeding hopper 101 at one time, and then the motor is started. The motor drives the screw rod 5 to rotate. By using the threaded connection and cooperation between the screw rod 5 and the connecting block 7, the feeding plate 6 can be driven to move to the right. During the movement of the feeding plate 6, when the receiving groove 8 communicates with the feeding hopper 101, the rubber particle raw materials inside the feeding hopper 101 will automatically enter the receiving groove 8, thus achieving the purpose of automatic feeding. And during the movement of the feeding plate 6, the toothed plate 105 can also be driven to move together. By using the meshing action between the toothed plate 105 and the gear 104, the rotating shaft 102 can be driven to rotate. The rotation of the rotating shaft 102 drives the stirring rod 103 to rotate, and the stirring rod 103 can stir the rubber particles, thereby preventing blockage caused by excessive friction between the rubber particles and between the rubber particles and the inner wall of the feeding hopper 101, ensuring the smoothness of the material discharge. When the feeding plate 6 moves to the rightmost side of the processing table 1, the electric push rod 2 is started, and the electric push rod 2 will push the pressing block 4 to perform an extrusion operation on the rubber particles in the receiving groove 8. At this time, the first magnet block 206 will contact and adsorb with the second magnet block 207, and the baffle plate 106 will block the discharge port of the feeding hopper 101. When the processing is completed, the feeding plate 6 is driven to move to the left by the motor. Due to the mutual adsorption of the first magnet block 206 and the second magnet block 207, the feeding plate 6 will move separately first. When the receiving groove 8 communicates with the discharging groove 202, the rubber inside the receiving groove 8 will automatically fall onto the receiving plate 9, thus achieving the purpose of automatic discharging. At the same time, by using the sliding fit between the slider 203 and the sliding rod 204, when the feeding plate 6 moves, the slider 203 will stretch or compress the spring 205. When the end of the sliding rod 204 contacts the slider 203, at this time, the feeding plate 6 will drive the baffle plate 201 to move together. When the first magnet block 206 is separated from the second magnet block 207, due to the elastic return of the spring 205, the baffle plate 201 will automatically reset, thus facilitating the normal use of the subsequent device. Finally, the rubber on the receiving plate 9 is collected.

[0037] Embodiment 2:

[0038] On the basis of Embodiment 1, the further improvement in this embodiment is that: the size of the receiving groove 8 is the same as that of the discharging groove 202, which is convenient for the rubber inside the receiving groove 8 to smoothly fall out through the discharging groove 202.

[0039] The above-mentioned implementation manners are only the preferred implementation manners of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the protection scope required by the present invention.
