Description

Technical Field

[0001] This utility model relates to the field of plastic product manufacturing technology, specifically to a raw material dryer for plastic product manufacturing. Background Technology

[0002] Plastic product manufacturing refers to the process of using plastic raw materials to manufacture various plastic products through processing technology. These plastic products are widely used in various fields of daily life, such as automobiles, home appliances, packaging, electronic products and medical devices. In plastic product manufacturing, drying the raw materials is a very critical step, mainly to remove the moisture in the plastic raw materials. If the moisture is not effectively removed, it will have an adverse effect on the processing quality of the plastic and the performance of the final product.

[0003] In existing technologies, plastic raw material granules are prone to absorbing environmental moisture during storage and transportation. If the moisture is not fully removed, it will lead to a decline in the quality of plastic products during high-temperature processing. Currently, hot air circulation drying equipment is commonly used for drying plastic raw material granules. However, hot air circulation drying equipment has the problem of uneven drying. The accumulation of raw materials in the static drying chamber leads to poor hot air penetration and a large difference in humidity between the inner and outer layers, which will lead to a decline in the quality of plastic products during high-temperature processing.

[0004] Therefore, a raw material dryer for plastic product manufacturing is proposed to solve the above-mentioned technical problem of uneven drying. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a raw material dryer for plastic product manufacturing, which has the advantage of uniform drying and solves the problems of poor hot air penetration and large humidity differences between the inner and outer layers caused by raw material accumulation in the static drying chamber.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a raw material dryer for plastic product production, which is mounted on a support and includes a drying chamber mounted on the support, wherein a vibration component is mounted on the drying chamber;

[0007] The vibration assembly includes a connector disposed at the bottom of the drying chamber. Two shafts are symmetrically arranged on the connector. Rollers are rotatably connected to both ends of the shafts, and the rollers are slidably connected to the support. A drive assembly connected to the connector is disposed on the support, and the drive assembly is used to drive the drying chamber to perform lateral reciprocating motion.

[0008] Furthermore, a groove is provided on the bracket corresponding to the roller, and the roller is slidably connected in the groove.

[0009] Furthermore, a drive module is mounted on the bracket, and a rotating component is provided on the outer side of the output shaft of the drive module. A connecting pin is provided on the side of the rotating component away from the drive module, and the connecting pin is not concentric with the rotating component.

[0010] Furthermore, a sleeve is fitted on the outer side of the connecting pin, and a drive rod is provided on the sleeve.

[0011] Furthermore, the end of the drive rod away from the sleeve is hinged to the connector via a hinge bracket.

[0012] Furthermore, a drying pipe is connected to one side of the drying chamber, and the end of the drying pipe away from the drying chamber is connected to an external drying fan. Several air holes are opened on the side of the drying chamber corresponding to the exhaust end of the drying pipe, and the air holes are evenly spaced on the drying chamber.

[0013] Furthermore, the drying chamber is a cuboid with a hollow interior and a missing upper surface, and a sealing plug is detachably connected to the drying chamber.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] 1. This raw material dryer for plastic product production drives the drying chamber to make lateral reciprocating motion through a vibration component, causing the plastic particles inside the chamber to continuously tumble, breaking the clumping phenomenon caused by static accumulation. The dynamic changes in the particle gaps significantly improve the hot air penetration efficiency. The lateral vibration of the drying chamber forces the particle layer to continuously recombine, forming a three-dimensional convection drying environment. Hot air can penetrate deep into the particle gaps, making the plastic raw material particles in the drying chamber dry evenly.

[0016] 2. The raw material dryer for plastic product production adopts an eccentric drive structure. The rotating part 306, connecting pin 307 and sleeve 308 convert the rotational motion of the drive module 305 into linear reciprocating vibration, so that the plastic raw material particles in the drying chamber are always in motion, and the plastic raw material particles are in full contact with the hot air sent in by the drying tube, which further improves the drying effect of the plastic raw material particles.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Please see Figure 1 In this embodiment, a raw material dryer for plastic product production is provided on a support 100, including a drying chamber 200 provided on the support 100, and a vibration component 300 provided on the drying chamber 200.

[0027] The vibration assembly 300 includes a connector 301 disposed at the bottom of the drying chamber 200. Two shafts 302 are symmetrically disposed on the connector 301. Rollers 303 are rotatably connected to both ends of the shafts 302. The rollers 303 are slidably connected to the support 100. A drive assembly is disposed on the support 100 and connected to the connector 301. The drive assembly is used to drive the drying chamber 200 to perform lateral reciprocating motion.

[0028] In application, the plastic raw material granules to be dried are first added into the drying chamber 200. At this time, the drive component is started, which drives the connector 301 to swing back and forth in the lateral direction, thereby driving the drying chamber 200 to swing back and forth in the lateral direction. At this time, the roller 303 set on the shaft 302 slides on the bracket 100, ensuring the stability of the drying chamber 200 when it moves. As the drying chamber 200 moves back and forth, the plastic raw material granules in the drying chamber 200 are kept in motion, breaking the clumping phenomenon caused by static accumulation. Hot air can penetrate deep into the gaps between the granules, so that the plastic raw material granules in the drying chamber 200 are dried evenly.

[0029] Example 2:

[0030] The basic content is the same as in Example 1, except that:

[0031] Please see Figure 2-6 In this embodiment, a groove 304 is provided on the bracket 100 corresponding to the roller 303, and the roller 303 is slidably connected in the groove 304.

[0032] It should be noted that the drying chamber 200 is restricted to moving horizontally only in the lateral direction. The cooperation between the roller 303 and the slide 304 ensures the stability of the vibration process and prevents the drying chamber 200 from shifting or getting stuck.

[0033] A drive module 305 is mounted on the bracket 100. A rotating part 306 is provided on the outer side of the output shaft of the drive module 305. A connecting pin 307 is provided on the side of the rotating part 306 away from the drive module 305, and the connecting pin 307 is not concentric with the rotating part 306.

[0034] It should be noted that the drive module 305 is connected to the control unit, and the control unit controls the output shaft of the drive module 305 to rotate, so that the rotating part 306 rotates at a uniform speed. The control unit and its working principle are well known to those skilled in the art, and will not be described in this embodiment.

[0035] Preferably, the drive module 305 in this application is a servo motor.

[0036] A sleeve 308 is fitted on the outer side of the connecting pin 307, and a drive rod 309 is provided on the sleeve 308.

[0037] The end of the drive rod 309 away from the sleeve 308 is hinged to the connector 301 via a hinge bracket.

[0038] When in use, the drive module 305 starts, causing the rotating part 306 to rotate. Due to the eccentric setting of the connecting pin 307 and the rotating part 306, the connecting pin 307 makes a circular motion around the center of the rotating part 306. The circular motion of the connecting pin 307 is transmitted to the drive rod 309 through the sleeve 308, forcing the drive rod 309 to make a lateral reciprocating swing. The drive rod 309 pushes the connecting part 301 through the hinge frame, converting the swing into linear displacement. The connecting part 301 is driven by the driving force to move the drying chamber 200 in the horizontal direction. The symmetrically arranged rollers 303 roll in the slide groove 304 of the bracket 100, constraining the motion trajectory to be a pure lateral reciprocating vibration. The lateral vibration of the drying chamber 200 forces the plastic particles in the chamber to continuously tumble, breaking the static accumulation state.

[0039] Example 3:

[0040] The basic content is the same as in Example 1, except that:

[0041] Please see Figure 2-3In this embodiment, a drying pipe 201 is connected to one side of the drying chamber 200. The end of the drying pipe 201 away from the drying chamber 200 is connected to an external drying fan. Several air holes 202 are opened on one side of the drying chamber 200 corresponding to the exhaust end of the drying pipe 201. Several air holes 202 are equally spaced on the drying chamber 200.

[0042] The drying chamber 200 is a cuboid with a hollow interior and a missing upper surface, and a sealing plug is detachably connected to the drying chamber 200.

[0043] It should be noted that the design of the top opening and sealing plug of the drying chamber 200 facilitates subsequent maintenance of the drying chamber 200.

[0044] In application, the drying chamber 200 is connected to the drying pipe 201 on the side wall, and the drying pipe 201 is connected to the drying fan to form a closed-loop hot air circulation. The drying chamber 200 has equally spaced air holes 202 on the inner wall to ensure that the airflow penetrates the plastic raw material granule layer evenly.

[0045] In summary, the working principle of this raw material dryer for plastic product manufacturing is as follows:

[0046] First, the plastic raw material granules to be dried are added into the drying chamber 200. The drive module 305 is activated, causing the rotating part 306 to rotate. Due to the eccentric setting of the connecting pin 307 and the rotating part 306, the connecting pin 307 moves in a circular motion around the center of the rotating part 306. The circular motion of the connecting pin 307 is transmitted to the drive rod 309 through the sleeve 308, forcing the drive rod 309 to swing laterally. The drive rod 309 pushes the connecting part 301 through the hinge frame, converting the swing into linear displacement. The connecting part 301 is driven... The power source drives the drying chamber 200 to move horizontally. The symmetrically arranged rollers 303 roll in the grooves 304 of the support 100, constraining the movement trajectory to be a pure lateral reciprocating vibration. The lateral vibration of the drying chamber 200 forces the plastic particles inside the chamber to continuously tumble, breaking the static accumulation state. At the same time, hot air is introduced through the drying pipe 201 and evenly penetrates the particle layer through the equally spaced air holes 202. The vibration and hot air work together to expand the gaps between the particles and reduce the penetration resistance of the hot air. The hot air carries away the moisture on the surface of the tumbling particles, achieving deep drying.
