Description

Technical Field

[0001] This utility model relates to the field of plastic masterbatch, and in particular to a vibratory feeding device for functional plastic masterbatch. Background Technology

[0002] Plastic masterbatch is a high-concentration additive premix that is widely used in the plastics processing industry. It is a granular material made by melting, mixing and granulating one or more functional additives with a carrier resin at high temperature.

[0003] A vibratory feeding device for functional plastic masterbatch is a mechanical device specifically designed for efficient, uniform, and controllable material conveying during the processing or production of plastic masterbatch.

[0004] The existing vibratory feeding device for functional plastic masterbatch has the following shortcomings:

[0005] In the plastic masterbatch processing stage, the conventional operating logic of the feeding device relies on the opening and closing of valves to feed the masterbatch to various processing equipment. However, this static feeding method that relies on valve opening and closing has significant drawbacks in actual operation. Because plastic masterbatch itself may be statically charged, prone to sticking when damp, or have gaps due to uneven particle size, it is very easy for them to squeeze and accumulate when passing through the valve channel, thus blocking the valve's feeding port. Once the valve is blocked, the originally smooth feeding path is blocked, and the masterbatch cannot pass through smoothly, directly resulting in a significant reduction in feeding speed. This blockage problem not only requires frequent shutdowns to clean the valves and interrupt the production process, but also seriously drags down the overall processing rhythm due to unstable feeding volume and low conveying efficiency. Utility Model Content

[0006] This invention enables the material box to reciprocate at high frequency along the chute, ensuring that the material remains in a loose state and avoiding accumulation and bridging, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a vibratory feeding device for functional plastic masterbatch, comprising a feeding mechanism, the bottom of which is fixedly connected to a set of support mechanisms; the feeding mechanism includes a frame, the inner wall of which is fixedly connected to a set of fixing plates, the inner wall of which is movably inserted with a set of cams, the top of which is fixedly installed with a set of servo motors, the inner wall of which is provided with sliding grooves, the inner wall of which is slidably connected with sliders, the outer wall of which is fixedly connected with a material box, the inner wall of which is fixedly connected with guide rods, and the outer wall of which is respectively fitted with a first compression spring and a second compression spring. Through the above components, a mechanical vibration drive core is constructed, replacing the traditional valve static feeding, and structurally avoiding the clogging problem caused by masterbatch adhesion and agglomeration.

[0008] Preferably, the bottom of the frame is fixedly connected to a discharge ramp, the output end of the servo motor is fixedly connected to the top of the cam, and the discharge ramp is designed to be inclined to use gravity to assist in feeding, reduce the accumulation of masterbatch at the outlet, and improve feeding efficiency.

[0009] Preferably, a PLC controller is fixedly installed on one side of the front of the frame. The PLC controller is electrically connected to the components to control the opening and closing of the components.

[0010] Preferably, a set of baffles is fixedly connected to the outer wall of the fixed plate, and the bottom of the inner wall of the material box is provided with screen holes. The baffles can prevent the masterbatch from splashing during vibration, thus avoiding material waste and pollution of the working environment.

[0011] Preferably, the outer wall of the guide rod is slidably connected to the inner wall of the slider, one end of the first compression spring and the second compression spring are fixedly connected to the inner wall of the slide groove, and the other end of the first compression spring and the second compression spring are fixedly connected to the outer wall of the slider. The guide rod provides rigid guidance for the movement of the slider, ensuring that the material box vibrates only in the horizontal direction and avoiding structural wear or unstable feeding caused by lateral displacement.

[0012] Preferably, the support mechanism includes support legs, each of which is fixedly equipped with a damper at its top. The outer wall of each damper is fitted with a spring, and a set of connecting blocks is fixedly connected to the shaft end of the damper. The outer wall of the connecting blocks is fixedly connected to the outer wall of the discharge inclined plate. The damper and springs combine to form a multi-stage vibration reduction structure, which can absorb the high-frequency vibration of the feeding mechanism, prevent the vibration from being transmitted to the ground and causing the overall equipment to shake or become too noisy, and improve the stability of operation.

[0013] Preferably, one end of the spring is fixedly connected to the top of the support leg, and the other end of the spring is fixedly connected to the bottom of the connecting block. The elastic deformation of the spring can adapt to the vibration displacement of the feeding mechanism, while providing an upward supporting force for the connecting block, balancing the weight of the equipment and the vibration impact force, and extending the service life of the support structure.

[0014] Preferably, a set of lifting plates is slidably connected to the inner wall of the support leg. Each lifting plate has a fixedly installed caster wheel at its bottom. Each support leg has a fixedly connected sliding rod at its top inner wall. The shaft end of the sliding rod is fixedly connected to the top of the lifting plate. The caster wheel enables the device to move flexibly, making it easy to adjust the position of the equipment according to production needs and solving the problem of difficult handling of traditional fixed equipment.

[0015] Preferably, a set of electric push rods is fixedly installed on the outer wall of the support leg. The shaft end of the electric push rod is fixedly connected to the top of the lifting plate. The electric push rod drives the lifting plate to achieve automatic lifting and lowering, thereby switching the ground-contact and ground-free states of the moving wheels. When the equipment moves, the moving wheels descend to the ground. When the equipment is fixed in place, the moving wheels automatically retract, eliminating the need for manual handling and effectively saving labor costs.

[0016] Preferably, the bottom of each support leg is fixedly connected with an anti-slip pad. The anti-slip pad increases the friction between the support leg and the ground, preventing slippage when the equipment is running or vibrating. It can significantly improve stability, especially on smooth surfaces (such as workshop cement floors).

[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0018] 1. In this utility model, a mechanical vibration drive system consisting of a servo motor, cam, slider, compression spring, and material box fundamentally replaces the static feeding mode of traditional valves, effectively solving the problem of material blockage caused by electrostatic adsorption, adhesion, or agglomeration of plastic masterbatch. The servo motor drives the cam to rotate, and with the guiding action of the guide rod and the elastic reset function of the first and second compression springs, the material box achieves high-frequency left-right reciprocating vibration along the slide, ensuring that the material remains in a loose state and avoiding accumulation and bridging. In addition, the bottom of the material box is equipped with a sieve hole, which can simultaneously screen out impurities and agglomerated materials during the feeding process, significantly improving the purity of the feeding. The discharge inclined plate at the bottom of the frame achieves smooth material conveying by gravity, effectively reducing material accumulation at the outlet.

[0019] 2. In this utility model, the support mechanism adopts a multi-stage vibration reduction structure composed of dampers and springs, which effectively absorbs the high-frequency vibration generated by the feeding mechanism, significantly reducing the overall shaking amplitude and operating noise of the equipment, thereby improving the comfort of the working environment. The anti-slip pads equipped at the bottom of the support legs enhance the friction with the ground, effectively preventing the equipment from slipping due to vibration during operation, further ensuring the stability of the equipment. In addition, the electric push rod drives the lifting plate to drive the moving wheels to achieve automatic lifting, enabling the equipment to have both flexible movement and stable fixation functions. When the position needs to be adjusted, the equipment can be easily moved without manual handling, significantly saving labor costs. This design can flexibly adapt to the layout requirements of different production scenarios, comprehensively improving the practicality and ease of operation of the equipment.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Please see Figures 1-5This utility model provides a technical solution: a vibratory feeding device for functional plastic masterbatch, including a feeding mechanism 1, a set of support mechanisms 2 fixedly connected to the bottom of the feeding mechanism 1; the feeding mechanism 1 includes a frame 101, a set of fixing plates 104 fixedly connected to the inner wall of the frame 101, a set of cams 106 movably inserted into the inner wall of the fixing plates 104, a set of servo motors 105 fixedly installed on the top of the fixing plates 104, a sliding groove 110 is opened on the inner wall of the frame 101, a slider 111 is slidably connected to the inner wall of the sliding groove 110, a material box 107 is fixedly connected to the outer wall of the slider 111, a guide rod 112 is fixedly connected to the inner wall of the sliding groove 110, and a first compression spring 113 and a second compression spring 114 are respectively sleeved on the outer wall of the guide rod 112. Through the above components, a mechanical vibration drive core is constructed, replacing the traditional valve static feeding, and structurally avoiding the blockage problem caused by masterbatch adhesion and agglomeration.

[0029] like Figure 2 and Figure 3 As shown, the bottom of the frame 101 is fixedly connected to the discharge ramp 109, and the output end of the servo motor 105 is fixedly connected to the top of the cam 106. The discharge ramp 109 adopts an inclined design, which uses gravity to assist in feeding, reduces the accumulation of masterbatch at the outlet, and improves feeding efficiency.

[0030] like Figure 2 As shown, a PLC controller 102 is fixedly installed on one side of the front of the frame 101. The PLC controller 102 is electrically connected to the components to control the opening and closing of the components.

[0031] like Figure 2 and Figure 3 As shown, a set of baffles 103 are fixedly connected to the outer wall of the fixed plate 104, and the bottom of the inner wall of the material box 107 is provided with screen holes 108. The baffles 103 can block the masterbatch from splashing during vibration, thus avoiding material waste and pollution of the working environment.

[0032] like Figure 4 As shown, the outer wall of the guide rod 112 is slidably connected to the inner wall of the slider 111. One end of the first compression spring 113 and the second compression spring 114 is fixedly connected to the inner wall of the slide groove 110, and the other end of the first compression spring 113 and the second compression spring 114 is fixedly connected to the outer wall of the slider 111. The guide rod 112 provides rigid guidance for the movement of the slider 111, ensuring that the material box 107 vibrates only in the horizontal direction, avoiding structural wear or unstable feeding caused by lateral displacement.

[0033] like Figure 5As shown, the support mechanism 2 includes support legs 201. Each support leg 201 is fixedly mounted with a damper 207. The outer wall of each damper 207 is fitted with a spring 208. A set of connecting blocks 209 are fixedly connected to the shaft end of the damper 207. The outer wall of the connecting block 209 is fixedly connected to the outer wall of the discharge inclined plate 109. The damper 207 and the spring 208 are combined to form a multi-stage vibration reduction structure, which can absorb the high-frequency vibration of the feeding mechanism 1, prevent the vibration from being transmitted to the ground and causing the overall equipment to shake or the noise to be too loud, and improve the stability of operation.

[0034] like Figure 5 As shown, one end of the spring 208 is fixedly connected to the top of the support leg 201, and the other end of the spring 208 is fixedly connected to the bottom of the connecting block 209. The elastic deformation of the spring 208 can adapt to the vibration displacement of the feeding mechanism 1, and at the same time provide an upward support force for the connecting block 209, balancing the weight of the equipment and the vibration impact force, and extending the service life of the support structure.

[0035] like Figure 5 As shown, a set of lifting plates 204 are slidably connected to the inner wall of the support leg 201. Each lifting plate 204 has a fixedly installed caster wheel 203 at its bottom. Each support leg 201 has a fixedly connected sliding rod 206 at its top. The shaft end of the sliding rod 206 is fixedly connected to the top of the lifting plate 204. The caster wheel 203 enables the device to move flexibly, making it easy to adjust the position of the equipment according to production needs and solving the problem of difficult handling of traditional fixed equipment.

[0036] like Figure 5 As shown, a set of electric push rods 205 are fixedly installed on the outer wall of the support leg 201. The shaft end of the electric push rod 205 is fixedly connected to the top of the lifting plate 204. The electric push rod 205 drives the lifting plate 204 to achieve automatic lifting and lowering, thereby switching the grounding and off-ground states of the moving wheel 203. When the equipment moves, the moving wheel 203 descends to the ground. When it is positioned and fixed, the moving wheel 203 automatically retracts, eliminating the need for manual handling and effectively saving labor costs.

[0037] like Figure 5 As shown, the bottom of each support leg 201 is fixedly connected with an anti-slip pad 202. The anti-slip pad 202 increases the friction between the support leg 201 and the ground, preventing slippage when the equipment is running or vibrating. It can significantly improve stability, especially on smooth surfaces (such as workshop cement floors).

[0038] The usage and working principle of this device are as follows: First, start the servo motor 105 through the control panel on the PLC controller 102. The output end of the servo motor 105 drives a set of cams 106 that are movably inserted into the inner wall of the fixed plate 104 to rotate. During the rotation, the set of cams 106 alternately abut against the material box 107. When one of the cams 106 pushes the material box 107, the material box 107 slides along the slide groove 110 opened on the inner wall of the frame 101 through the slider 111 fixedly connected to the outer wall. At this time, the slider 111 slides along the inner wall of the slide groove 110. The movement of the fixed guide rod 112 compresses the first compression spring 113 or the second compression spring 114 on that side. When the cam 106 rotates to the non-abutting state, the compressed first compression spring 113 or the second compression spring 114, with the help of elastic restoring force, pushes the slider 111 and the material box 107 to move in the opposite direction. Combined with the abutting action of the cam 106 on the other side, the material box 107 achieves high-frequency left-right reciprocating vibration, ensuring that the plastic masterbatch in the material box 107 remains in a loose state, effectively avoiding the problem of poor material feeding caused by accumulation or bridging. During the vibration process, the masterbatch... After being screened by the sieve holes 108 at the bottom of the inner wall of the material box 107, the material falls into the discharge inclined plate 109 fixedly connected to the bottom of the frame 101, and is smoothly conveyed under the action of gravity. At the same time, the vibration generated by the feeding mechanism 1 is transmitted through the connecting block 209 to the damper 207 and spring 208 at the top of the support leg 201 in the support mechanism 2. The combined structure of the damper 207 and spring 208 can efficiently absorb high-frequency vibration, significantly reducing the overall shaking and operating noise of the equipment. The bottom of the support leg 201 is equipped with an anti-slip pad 202, which effectively increases the slip resistance. The strong friction with the ground prevents slippage during operation and further enhances equipment stability. When the equipment needs to be moved, the lifting plate 204 can be driven by the electric push rod 205 to descend along the slide rod 206, so that the moving wheel 203 touches the ground, enabling flexible movement. When the equipment is fixed, the moving wheel 203 can be retracted by the electric push rod 205, so that the equipment can operate stably in the working state. The whole system integrates automated vibration feeding, multi-level vibration reduction and noise reduction and automatic movement functions, and has the advantages of compact structure, stable operation, convenient operation and strong adaptability.

[0039] The PLC controller 102, servo motor 105, damper 207, and electric actuator 205 used in this application are all common equipment on the market and are well known to those skilled in the art. In this application, the above equipment is used in a conventional manner without any improvement to its structure and function. As for their settings, installation, and electrical connection methods, those skilled in the art can debug and operate them according to the corresponding product instruction manuals, so they will not be described in detail here.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
