Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to an injection molding machine which is easy to clean and is used for cap production. Background Art

[0002] Cleaning the injection molding machine is crucial during the cap production process. During the injection molding process, the plastic raw materials used in cap production can leave various residues on the surfaces of components such as the barrel and mold. These residues not only affect product quality but can also negatively impact the performance and lifespan of the injection molding machine.

[0003] However, when cleaning the material barrel of an existing injection molding machine, it is often necessary to manually disassemble parts for cleaning, which not only consumes a lot of manpower and time, but also has a poor cleaning effect. The material residue will not only adhere to the barrel wall to form stubborn residue, but will also accumulate more and more as production continues. This residue not only wastes material, but also affects the flow and processing of the material. For example, during the injection molding process, the residual material may hinder the normal flow of the material in the barrel, resulting in quality problems of the injection molded product, such as uneven product surface, bubbles, etc., which reduces the production quality. For this reason, we provide an injection molding machine that is easy to clean for capping production. Utility Model Content

[0004] The purpose of the utility model is to provide an injection molding machine for cap production that is easy to clean, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: an injection molding machine for cap production that is easy to clean, comprising a machine body, a material barrel fixedly mounted on the machine body, a fixed component and a movable component provided inside the material barrel for facilitating cleaning of the inner wall of the material barrel, and the movable component comprising:

[0006] A fixing frame is fixedly installed on the top of the material barrel. A control motor is fixedly installed on the surface of the fixing frame. A rotating shaft is fixedly installed on the surface of the output shaft of the control motor. When the material is placed in the material barrel for injection molding, the control motor is started to drive the rotation of the rotating shaft. The rotating shaft is rotatably connected to the top of the material barrel.

[0007] Preferably, a sliding rod is slidably connected to the surface of the rotating shaft, a connecting rod is fixedly installed on the surface of the sliding rod, and the connecting rod passes through the material barrel.

[0008] Preferably, a positioning block is fixedly installed inside the material barrel, the connecting rod passes through the positioning block, a rotating rod is fixedly installed at the bottom of the rotating shaft, and a telescopic rod 1 is fixedly installed on the surface of the rotating rod. When the sliding rod slides downward, it will abut against the top of the movable disk and drive the movable disk connected by the telescopic rod 1 to extend, and when the rotating shaft rotates, it will also drive the rotation of the bottom rotating rod, and when the rotating rod rotates, it will drive the rotation of the movable disk. A fixed spring is fixedly installed inside the telescopic rod 1, and a movable disk is fixedly installed at the bottom of the telescopic rod 1.

[0009] Preferably, a connecting block is fixedly mounted on the top of the movable disk, and a second telescopic rod is fixedly mounted inside the connecting block. When the second telescopic rod is extended, it drives the sliding block to slide inside the connecting block. When the sliding block slides, it drives the scraper to move toward the inner wall of the material barrel. When the scraper moves, it adheres to the inner wall of the material barrel and cleans the inner wall of the material barrel, preventing the material from adhering to the barrel wall and forming stubborn residue, thereby reducing material waste. As production continues, if the residual material is not cleaned in time, it will accumulate, thereby affecting the flow and processing of subsequent materials, improving product production quality and enhancing the convenience of cleaning. A movable spring is fixedly mounted on the surface of the second telescopic rod, and a sliding block is fixedly mounted on the surface of the second telescopic rod. The sliding block is slidably connected to the inside of the connecting block, and a scraper is fixedly mounted on the outside of the sliding block.

[0010] Preferably, the fixing assembly includes: a fixing block, which controls the centrifugal force to disappear when the motor stops and starts, so that the telescopic rod 2 will reset under the action of the movable spring and drive the scraper to move toward the surface close to the movable disk. The fixing block is fixedly installed on the outside of the movable disk, and a hanging strip is fixedly installed on the inside of the fixing block. When the scraper is reset, the hanging strip on the inside of the fixing block will drive the hanging strip on the surface of the scraper to process the adhesion on the surface of the scraper. The adhesion on the scraper surface will dry and harden with time and environmental factors, becoming more difficult to remove, affecting the cleaning effect of the scraper next time it is used, and increasing the service life of the scraper.

[0011] Preferably, two groups of the fixing components are provided, and the two groups of fixing components are symmetrically arranged with the center point of the movable disk as the symmetry axis.

[0012] Preferably, a reciprocating groove is provided on the surface of the rotating shaft, and the sliding rod can be driven to slide reciprocatingly up and down by the rotation of the rotating shaft.

[0013] Compared with the prior art, the present invention provides an injection molding machine for cap production that is easy to clean, and has the following beneficial effects:

[0014] 1. The capping production injection molding machine is easy to clean. Through the setting of the movable component, the rotation of the rotating rod is driven by starting the control motor. When the rotating rod rotates, it drives the rotation of the movable disk. When the movable disk rotates, it drives the extension of the telescopic rod 2 through centrifugal force. When the telescopic rod 2 extends, it drives the sliding block to slide inside the connecting block. When the sliding block slides, it drives the scraper to move toward the inner wall of the material barrel. When the scraper moves, it fits on the inner wall of the material barrel and cleans the inner wall of the material barrel to prevent the material from adhering to the barrel wall to form stubborn residue, thereby improving product production quality and enhancing the convenience of cleaning.

[0015] 2. The capping production injection molding machine is easy to clean. Through the setting of the fixed component, when the inner wall of the material barrel is cleaned, the start of the control motor can be stopped. When the control motor stops starting, the centrifugal force will disappear, so that the telescopic rod 2 will be reset under the action of the movable spring, and drive the scraper to move toward the surface close to the movable disk. When the scraper is reset, it will drive the hanging strip on the inside of the fixed block to process the adhesion on the surface of the scraper. The adhesion on the scraper surface will dry and harden with time and environmental factors, becoming more difficult to remove, affecting the cleaning effect of the scraper next time it is used, and increasing the service life of the scraper.

[0021] like Figures 1-4As shown, the utility model provides a technical solution: an injection molding machine that is easy to clean for capping production, comprising a machine body 1, a material barrel 2 is fixedly mounted on the machine body 1, a fixed component 3 and a movable component 4 are provided inside the material barrel 2 for facilitating cleaning of the inner wall of the material barrel 2, and the movable component 4 comprises: a fixed frame 41, a control motor 42, a rotating shaft 43, a sliding rod 44, a connecting rod 45, a positioning block 46, a rotating rod 47, a telescopic rod 1 48, a fixed spring 49, a movable disk 410, a connecting block 411, a telescopic rod 2 412, a movable spring 413, a sliding block 414, and a scraper 415.

[0022] The fixing frame 41 is fixedly installed on the top of the material barrel 2, and a control motor 42 is fixedly installed on the surface of the fixing frame 41, and a rotating shaft 43 is fixedly installed on the surface of the output shaft of the control motor 42. By placing the material in the material barrel 2 and performing injection molding, when the material barrel 2 is in use, the rotation of the rotating shaft 43 can be driven by starting the control motor 42. The rotating shaft 43 is rotatably connected to the top of the material barrel 2, and a sliding rod 44 is slidably connected on the surface of the rotating shaft 43. A connecting rod 45 is fixedly installed on the surface of the sliding rod 44. The connecting rod 45 passes through the material barrel 2, and a positioning block 46 is fixedly installed inside the material barrel 2. The connecting rod 45 passes through the positioning block 46. A rotating rod 47 is fixedly installed on the bottom of the rotating shaft 43, and a telescopic rod 48 is fixedly installed on the surface of the rotating rod 47. When the sliding rod 44 slides downward, it will interfere with the top of the movable disk 410 and drive the material barrel 2 to move forward. The movable disk 410 connected to the rod 1 48 is extended, and when the rotating shaft 43 rotates, it also drives the rotation of the bottom rotating rod 47. When the rotating rod 47 rotates, it drives the rotation of the movable disk 410. A fixed spring 49 is fixedly installed inside the telescopic rod 1 48, and a movable disk 410 is fixedly installed at the bottom of the telescopic rod 1 48. A connecting block 411 is fixedly installed on the top of the movable disk 410, and a telescopic rod 2 412 is fixedly installed inside the connecting block 411. When the telescopic rod 2 412 is extended, it drives the sliding block 414 to slide inside the connecting block 411. When the sliding block 414 slides, it drives the scraper 415 to move toward the inner wall of the material barrel 2. When the scraper 415 moves, it fits against the inner wall of the material barrel 2 and cleans the inner wall of the material barrel 2 to prevent the material from adhering to the barrel wall to form stubborn residues, thereby reducing material waste. As production continues, if the residual materials are not cleaned in time, they will accumulate more and more, thereby affecting the flow and processing of subsequent materials, improving product production quality and enhancing the convenience of cleaning. A movable spring 413 is fixedly installed on the surface of the telescopic rod 412, and a sliding block 414 is fixedly installed on the surface of the telescopic rod 412. The sliding block 414 is slidably connected to the inside of the connecting block 411, and a scraper 415 is fixedly installed on the outside of the sliding block 414.

[0023] The fixing assembly 3 includes: a fixing block 31. When the control motor 42 stops starting, the centrifugal force disappears, so that the telescopic rod 2 412 will be reset under the action of the movable spring 413, and drive the scraper 415 to move toward the surface close to the movable disk 410. The fixing block 31 is fixedly installed on the outer side of the movable disk 410, and a hanging bar 32 is fixedly installed on the inside of the fixing block 31. When the scraper 415 is reset, the hanging bar 32 on the inside of the fixing block 31 will drive the hanging bar 32 on the inside of the fixing block 31 to process the adhesion on the surface of the scraper 415. The adhesion on the surface of the scraper 415 will dry and harden with time and environmental factors, becoming more difficult to remove, affecting the cleaning effect of the scraper 415 next time it is used, and improving the service life of the scraper 415. The fixing assembly 3 is provided with two groups, and the two groups of fixing assemblies 3 are symmetrically arranged with the center point of the movable disk 410 as the axis of symmetry. A reciprocating groove 430 is provided on the surface of the rotating shaft 43, which can drive the slide rod 44 to slide back and forth up and down by the rotation of the rotating shaft 43.

[0024] When the injection molding machine for cap production is used, the material can be placed in the material barrel 2 for injection molding, and the control motor 42 is started to drive the rotation of the shaft 43. When the shaft 43 rotates, the slide rod 44 is driven to slide downward. When the slide rod 44 slides downward, it will contact the top of the movable disk 410 and drive the movable disk 410 connected by the telescopic rod 48 to extend. When the shaft 43 rotates, it will also drive the rotation of the bottom rotating rod 47. When the rotating rod 47 rotates, it will drive the movable disk 410 to extend. As the disk 410 rotates, the centrifugal force of the movable disk 410 causes the extension of the second telescopic rod 412. The extension of the second telescopic rod 412 causes the sliding block 414 to slide within the connecting block 411. As the sliding block 414 slides, the scraper 415 moves toward the inner wall of the material barrel 2. As the scraper 415 moves, it adheres to the inner wall of the material barrel 2 and cleans the inner wall of the material barrel 2, preventing material from adhering to the barrel wall and forming stubborn residue, thereby reducing material waste. As production continues, if residual material is not cleaned in a timely manner, it will accumulate, thereby affecting the flow and processing of subsequent materials. This improves product quality and enhances cleaning convenience.

[0025] When the inner wall of the material barrel 2 is cleaned, the control motor 42 can be stopped. When the control motor 42 is stopped, the centrifugal force disappears, so that the telescopic rod 412 will be reset under the action of the movable spring 413, and drive the scraper 415 to move toward the surface close to the movable disk 410. When the scraper 415 is reset, it will drive the hanging bar 32 on the inner side of the fixed block 31 to process the adhesion on the surface of the scraper 415. The adhesion on the surface of the scraper 415 will dry and harden with time and environmental factors, becoming more difficult to remove, affecting the cleaning effect of the scraper 415 next time it is used, and increasing the service life of the scraper 415.

[0026] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
