Description

Technical Field

[0001] The invention belongs to the technical field of plastic bottle cap processing, in particular to a raw material mixing device and a mixing method for plastic bottle cap processing. Background Art

[0002] The raw material mixing device for plastic bottle cap processing is a special equipment designed for the raw material mixing needs in the production process of plastic bottle caps. The device is mainly used to mix different types of plastic raw materials (such as resin, PE, PP, PVC, etc.) in a certain proportion to meet the formula requirements of plastic bottle cap production.

[0003] The raw material mixing device is usually equipped with a stirring mechanism, including a stirring rod, stirring blades and other components. These components rotate or vibrate under the drive of the motor to stir the raw materials in the container. When the raw materials are put into the container, the stirring mechanism starts to work, and the rotation or vibration of the stirring rod and stirring blades will throw the raw materials to all corners of the container and achieve mixing through mutual contact and friction. This stirring method can ensure the uniform mixing of the raw materials, thereby improving the quality and performance of the bottle cap; However, this traditional plastic bottle cap raw material mixing equipment has many problems during use. The raw materials are often mixed directly before use, resulting in large particle impurities that may exist in the raw materials directly entering the mixing process, affecting the mixing effect and may even affect the quality of the final product. The traditional processing method is usually to perform simple mechanical screening before mixing, but these methods are often inefficient and have poor screening effects. It is also difficult to ensure sufficient mixing of the raw materials and the uniformity of the mixing process cannot be guaranteed. Summary of the invention

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figures 1 to 6 As shown, the present invention provides a raw material mixing device for processing plastic bottle caps, comprising a filter chamber 1, a filter element 2 is arranged inside the filter chamber 1, a swing mechanism 3 is arranged at one end of the filter element 2, a mixing box 4 is installed at the bottom of the filter chamber 1, a stirring element 5 is arranged inside the mixing box 4, and a material discharging element 6 is arranged at one end of the mixing box 4 opposite to the swing mechanism 3; The filter element 2 includes a screening plate 21 slidably connected to the inside of the filter bin 1, and the tops of both ends of the screening plate 21 are fixedly connected with return springs 22, and one end of the screening plate 21 close to the swing mechanism 3 is fixedly connected with an arc plate 23 through a fixing plate; The swing mechanism 3 includes a rotating rod 31 rotatably connected to the arc plate 23 , one end of the rotating rod 31 is rotatably connected to an eccentric wheel 32 , one end of the eccentric wheel 32 is fixedly connected to a connecting shaft 33 via a fixing seat, and one end of the connecting shaft 33 is provided with a driving member 34 .

[0021] The above scheme is adopted: the filter bin 1 serves as the upper structure of the overall device, providing space and support for the filtering process, the swing groove inside it provides guidance and limit for the swing of the screening plate 21, and the dust cover and the feed hopper on the top ensure the cleanliness and smoothness of the feeding, and the driving motor 35 is started by setting the cooperation of the swing mechanism 3 and the filter element 2 and other structures, and its output end drives the first guide wheel 36 to rotate, and the first guide wheel 36 drives the second guide wheel 38 to rotate through the synchronous belt 37, and at the same time, the first guide wheel 36 drives the connecting shaft 33 to rotate through the rotating shaft, and the connecting shaft 33 drives the eccentric wheel 32 to rotate, and the rotation of the eccentric wheel 32 causes the rotating rod 31 connected thereto to perform eccentric movement, and the rotating rod 31 pulls the arc plate 23, thereby driving the screening plate 21 to perform reciprocating swing in the swing groove. In this process, the raw materials are screened on the screening plate 21, and the raw materials that meet the size requirements fall into the mixing through the screening plate 21. The second guide wheel 38 is used to rotate the stirring rod 51, and the stirring blade 52 on the stirring rod 51 fully stirs and mixes the raw materials to make the raw materials evenly mixed. The stirring rod 51 is rotatably connected to the inner wall of the mixing box 4 through a bearing to ensure the smooth stirring process. The screening action comes first and the stirring action comes later. The two are naturally and orderly connected through the rotation of the second guide wheel 38. After the raw materials are screened on the screening plate 21, they fall directly into the mixing box 4. At this time, the stirring rod 51 starts to rotate driven by the transmission rod (associated with the second guide wheel 38), realizing seamless connection of the raw material processing flow. This sequence ensures that only qualified raw materials that have been screened enter the mixing link, avoiding the influence of impurities on the stirring process and the quality of the final product.

[0022] Example 1 Figures 1 to 6 As shown, a dust cover is provided on the top of the filter bin 1, a feed hopper is installed on the top of the dust cover, the feed hopper is connected to the filter bin 1, swing grooves adapted to the screening plate 21 are provided at both ends of the filter bin 1, and a fixed bin 101 is provided at one end of the filter bin 1 located at the swing mechanism 3, a telescopic spring 211 is fixedly connected to the end of the screening plate 21 away from the swing mechanism 3, one end of the telescopic spring 211 is slidably connected to a sliding bin 212 through a fixed pad, and the sliding bin 212 is connected to the end of the filter bin 1 away from the swing mechanism 3, and the reset The spring 22 is fixedly installed inside the swing groove, and the fixed seat includes a stabilizing block and a fixing rod. The stabilizing block is fixedly installed at the center position of one end of the eccentric wheel 32, one end of the fixing rod is fixedly connected to the inner wall of the stabilizing block, and the other end of the fixing rod is connected to the connecting shaft 33. The driving member 34 includes a driving motor 35 fixedly installed inside the fixed bin 101, and the output end of the driving motor 35 is splined with a first guide wheel 36, and the surface of the first guide wheel 36 is sleeved with a synchronous belt 37, and the interior of the synchronous belt 37 is sleeved with a second guide wheel 38.

[0023] The above scheme is adopted: the swing groove is opened at both ends of the filter bin 1 and is adapted to the screening plate 21, and its function is to provide space and movement guide for the swing of the screening plate 21, so that the screening plate 21 can stably swing back and forth within a certain range to ensure the normal progress of the screening action. The fixed bin 101 is located at one end of the filter bin 1 close to the swing mechanism 3, which provides installation space and a stable support structure for the driving member 34 and other related components to ensure the normal operation of the driving member 34, thereby driving the swing mechanism 3 to operate. One end of the telescopic spring 211 is connected to the screening plate 21, and the other end is slidably connected to the sliding bin 212 through a fixed pad. The telescopic spring 211 provides elastic restoring force for the screening plate 21. Under the drive of the swing mechanism 3, when the screening plate 21 swings, the telescopic spring 211 is stretched and retracted accordingly, and cooperates with the swing mechanism 3 during the swinging process, so that the screening plate 21 can continue to reciprocate. When the force of the swing mechanism 3 on the screening plate 21 disappears, the telescopic spring 211 can return the screening plate 21 to the initial position or maintain a certain tension state. The screening plate 21 is a key component for filtration; The raw materials are screened through their own meshes or gaps, and reciprocate under the action of the swing mechanism 3, which can prevent the raw materials from clogging the sieve holes and improve the filtering efficiency. The reset spring 22 is installed in the swing groove and is connected to the top of the screening plate 21, so that the screening plate 21 can return to the initial position after swinging, ensuring the continuous and stable filtering process. Through the setting of the discharge piece 6, the mixed raw materials enter the fixed frame 61. When discharging is required, the control valve on the output pipe is opened. When the raw materials pass through the fixed frame 61, the crushing wheel 63 on the bracket 62 can crush the possible agglomerated raw materials, and then discharge them through the output pipe to avoid output blockage, thereby improving production efficiency and reducing time waste and cost increase caused by downtime. Especially for large-scale and highly automated production operations, it can ensure the smooth execution of the production plan.

[0024] Example 2 Figures 1 to 6 As shown, one end of the first guide wheel 36 is connected to the connecting shaft 33 through a rotating shaft, one end of the second guide wheel 38 is fixedly connected to a transmission rod, the stirring member 5 includes a stirring rod 51 fixedly connected to the transmission rod, and a stirring blade 52 is fixedly installed on the surface of the stirring rod 51. Both ends of the stirring rod 51 are rotatably connected to the inner wall of the mixing box 4 through bearings. The discharging member 6 includes a fixed frame 61, a bracket 62 and a crushing wheel 63. The bracket 62 is fixedly connected to the inside of the fixed frame 61, and the crushing wheel 63 is fixedly installed on one side of the bracket 62. The bracket 62 and the crushing wheel 63 are both located inside the fixed frame 61. One end of the fixed frame 61 is through-connected with an output pipe, and a control valve is fixedly installed on the output pipe. The fixed frame 61 and the mixing box 4 are through-connected.

[0025] The above scheme is adopted: the mixing box 4 provides a closed space for the stirring and mixing process to ensure that the raw materials will not overflow during the stirring process. At the same time, its inner wall provides support for the stirring rod 51 through the bearing. The stirring rod 51 rotates under the drive of the transmission rod, and the stirring blade 52 stirs the raw materials to make the raw materials of different components fully mixed and uniform, so as to ensure the consistency of product quality. The driving motor 35: fixedly installed inside the fixed bin 101, is the power source of the entire swing mechanism 3. It provides power for the entire filtering and screening system through the rotation of the output shaft. The parameters such as the speed and torque of the driving motor 35 determine the movement speed and strength of the swing mechanism 3, and then affect the swing frequency and amplitude of the screening plate 21 to meet the needs of different materials and filtering requirements. The first guide wheel 36 is spline-connected to the output end of the driving motor 35. Its function is to transmit the rotational motion of the driving motor 35 to the synchronous belt 37. At the same time, the spline connection can ensure the stability and reliability of power transmission, avoid problems such as slipping during high-speed rotation, and ensure the effective transmission of power. The synchronous belt 37 is sleeved on the surfaces of the first guide wheel 36 and the second guide wheel 38. It is a flexible transmission component. In this system, the synchronous belt 37 transmits the power generated by the drive motor 35 from the first guide wheel 36 to the second guide wheel 38, so that the two can rotate synchronously, and can buffer and absorb vibrations during the transmission process to a certain extent, reduce noise, and maintain a stable transmission ratio to ensure the stable operation of the entire drive system. The second guide wheel 38 cooperates with the synchronous belt 37 to receive the power transmitted by the synchronous belt 37, and further transmits the power through connection with other components (such as the eccentric wheel 32, etc.), ultimately achieving the purpose of driving the screening plate 21 to swing.

[0026] The working principle and use process of the present invention are as follows: the raw material enters the filter bin 1 from the feed hopper, and the dust cover on the top of the feed hopper can prevent dust and impurities from mixing into the raw material during the feeding process; The screening plate 21 is in a stable position under the action of the return spring 22 and the telescopic spring 211. The return spring 22 is located in the swing groove to provide a restoring force for the screening plate 21 to return to the initial position. One end of the telescopic spring 211 is slidably connected to the sliding bin 212 through a fixed pad, so that the screening plate 21 can be flexibly moved within a certain range. The driving motor 35 is started, and its output end drives the first guide wheel 36 to rotate. The first guide wheel 36 drives the second guide wheel 38 to rotate through the synchronous belt 37. At the same time, the first guide wheel 36 drives the connecting shaft 33 to rotate through the rotating shaft. The connecting shaft 33 drives the eccentric wheel 32 to rotate. The rotation of the eccentric wheel 32 makes the rotating rod 31 connected thereto do eccentric movement. The rotating rod 31 pulls the arc plate 23, thereby driving the screening plate 21 to do reciprocating swing in the swing groove. In this process, the raw materials are screened on the screening plate 21, and the raw materials that meet the size requirements fall into the mixing box 4 through the screening plate 21, and the larger particles of impurities are left on the screening plate 21; After the screened raw materials enter the mixing box 4, the transmission rod rotates with the rotation of the second guide wheel 38, thereby driving the stirring rod 51 to rotate. The stirring blade 52 on the stirring rod 51 fully stirs and mixes the raw materials to make the raw materials mixed evenly. The stirring rod 51 is rotatably connected to the inner wall of the mixing box 4 through a bearing to ensure a smooth stirring process. The mixed raw materials enter the fixed frame 61. When the raw materials need to be discharged, the control valve on the output pipe is opened. When the raw materials pass through the fixed frame 61, the crushing wheel 63 on the bracket 62 can crush the possible agglomerated raw materials, and then discharge them through the output pipe.
