Description

Technical Field

[0001] This utility model relates to the field of medical plastic product processing equipment technology, and in particular to a reciprocating automatic feeding device for a rubber mixing mill. Background Technology

[0002] Current medical plastic products typically use a rubber mixing mill in the initial manufacturing step. The rubber dregs are usually placed between the rollers of the mill, and the mixing process is controlled by a touchscreen on the control cabinet. During the mixing process, appropriate amounts of desulfurizing agents and catalysts need to be added. The following problems exist in the current process: Desulfurizing agents and catalysts usually only need to be added in small amounts compared to the rubber balls. Therefore, they are mostly weighed manually and then the powder of various additives is shaken onto the rubber balls on the rollers. This process is manual. On the one hand, in order to maintain uniformity, a reciprocating shaking method may be used, which can easily slip out of the hand and cause the container or weighing paper to mix with the rubber balls and contaminate them. The efficiency is also relatively low. On the other hand, when people are in a state of tension while picking up fallen containers and papers, they may forget to stop the machine and subconsciously reach out to grab them, which can easily cause accidents. Utility Model Content

[0003] This utility model provides a reciprocating automatic feeding device for a rubber mixing mill, which aims to solve the problems mentioned above, such as the low efficiency and poor safety of the existing rubber mixing mills that rely on manual reciprocating shaking for the addition of additives.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: The reciprocating automatic feeding device for a rubber mixing mill includes mounting frames detachably mounted on the top of the machine body on both sides of the rubber mixing mill body. The mounting frames are arranged opposite each other. The top of each mounting frame is detachably equipped with a front-to-back displacement mechanism that moves along the front-to-back direction of the rubber mixing mill body. The moving ends of the front-to-back displacement mechanisms are connected by the same connecting plate to form synchronous movement. The top of the connecting plate is detachably equipped with an axial displacement mechanism that moves along the roller axis of the rubber mixing mill body. The moving end of the axial displacement mechanism is detachably equipped with a material release mechanism. Both ends of the axial displacement mechanism are equipped with sensing mechanisms to form a sensing engagement with the material release mechanism. The front-to-back displacement mechanism, the axial displacement mechanism, the sensing mechanism, and the material release mechanism are all electrically connected to the control cabinet of the rubber mixing mill body.

[0005] Preferably, the axial displacement mechanism is linked with the sensing mechanisms at both ends through the control cabinet of the rubber mixing machine body.

[0006] Preferably, the mounting frame includes a gantry frame vertically arranged on the top of the machine body, the top of the gantry frame extending along the front-rear direction of the rubber mixing machine body, and the front-rear displacement mechanism being parallel to the top of the gantry frame.

[0007] Preferably, one of the front-to-back displacement mechanisms on both sides is a conventional slide rail and the other is a first electric slide rail. Both the conventional slide rail and the first electric slide rail are slidably fitted with first sliders. The first slider on the first electric slide rail is linked to the first electric slide rail. The two first sliders are connected by the same connecting plate, and the two ends of the connecting plate are respectively connected to the top of the first slider on the corresponding side by invisible fasteners.

[0008] Preferably, the axial displacement mechanism includes a second electric slide rail, on which a second slider is slidably fitted, and the second slider and the second electric slide rail are linked together. Sensing mechanisms are respectively arranged at both ends of the second electric slide rail, and a material release mechanism is detachably fixedly installed on the top of the second slider.

[0009] Preferably, the sensing mechanisms are arranged opposite each other, and the sensing ends of the sensing mechanisms all point towards the material release mechanism along the roller axis.

[0010] Preferably, the sensing mechanism includes a sensor mounting base, on which a displacement sensor is detachably mounted.

[0011] Preferably, the material release mechanism includes a fixed bracket, on which a material storage tank is detachably fixedly mounted. The material storage tank is located away from the axial displacement mechanism via the fixed bracket. The bottom of the material storage tank is provided with a discharge port, and a solenoid valve is provided at the discharge port.

[0012] More preferably, the solenoid valve is a weighing solenoid valve.

[0013] More preferably, the fixed support includes a vertically arranged vertical frame, the bottom of which is fixed to the moving end of the axial displacement mechanism by a second base. An upper ring frame and a lower ring frame are respectively provided on the same side of the vertical frame. The upper ring frame is coaxially located above the lower ring frame. The material storage tank is embedded in the upper ring frame, and the bottom of the material storage tank is supported on the lower ring frame. The outer wall of the material storage tank is detachably fixed to the upper ring frame by fasteners.

[0014] The beneficial effects of this utility model are: 1.

Detailed Implementation

[0016] The embodiments will be further described below with reference to the accompanying drawings.

[0017] like Figures 1-6As shown in the preferred embodiment 1, the reciprocating automatic feeding device for the rubber mixing mill includes mounting frames 2 detachably mounted on the top of the machine body 101 on both sides of the rubber mixing mill body 1. The mounting frames 2 are arranged opposite to each other. The top of each mounting frame 2 is detachably provided with a front-to-back displacement mechanism 3 that moves along the front-to-back direction of the rubber mixing mill body 1. The moving ends of the front-to-back displacement mechanisms 3 are connected by the same connecting plate 4 to form synchronous movement. The top of the connecting plate 4 is detachably provided with an axial displacement mechanism 5 that moves along the axial direction of the roller 102 of the rubber mixing mill body 1. The moving end of the axial displacement mechanism 5 is detachably provided with a material release mechanism 7. Both ends of the axial displacement mechanism 5 are provided with sensing mechanisms 6 to form a sensing cooperation with the material release mechanism 7. The front-to-back displacement mechanism 3, the axial displacement mechanism 5, the sensing mechanism 6 and the material release mechanism 7 are all electrically connected to the control cabinet 103 of the rubber mixing mill body 1.

[0018] The axial displacement mechanism 5 is linked with the sensing mechanisms 6 at both ends through the control cabinet 103 of the rubber mixing machine body 1.

[0019] Before use, the material release mechanism 7 stays at the front end of the rubber mixing mill body 1. At this time, the staff can add materials to the material release mechanism 7 while away from the roller 102. The auxiliary materials in the rubber mixing process are weighed and added, such as desulfurizers, catalysts, etc. When in use, the front and rear displacement mechanism 3 is activated by the control cabinet 103 to move the material release mechanism 7 to a suitable position. If the discharge port of the material release mechanism 7 is above the top of the roller 102 on the front side, it can be moved closer to the middle position. After moving to a suitable position, the front and rear displacement mechanism 3 is braked to suspend the material release mechanism 7. Next, the left return distance 'a' and the right return distance 'b' are set via control cabinet 103, and reciprocating feeding is started. The axial displacement mechanism 5 is activated, and the suspended material release mechanism 7 feeds material axially above the top of the roller 102. When the material release mechanism 7 moves to the left, the sensing mechanism 6 on the left side monitors the distance in real time. When the monitored distance reaches the set distance a, the axial displacement mechanism 5 is controlled to reverse through the control cabinet 103, so that the material release mechanism 7 moves to the right. When the material release mechanism 7 moves to the right, the sensing mechanism 6 on the right side monitors the distance in real time. When the monitored distance reaches the set distance b, the axial displacement mechanism 5 is controlled to reverse through the control cabinet 103, so that the material release mechanism 7 moves to the left. Repeat the above process to achieve reciprocating motion. During the process, the material release mechanism 7 continuously feeds materials until feeding is completed. After feeding is completed, the operator closes the axial displacement mechanism 5 and the material release mechanism 7 through the control cabinet 103, and starts the front and rear displacement mechanism 3 to move the material release mechanism 7 forward until it reaches the front end of the rubber mixing mill 1, waiting for the next feeding.

[0020] In a preferred embodiment 2, the mounting frame 2 includes a gantry frame 201 vertically arranged on top of the machine body 101. The top of the gantry frame 201 extends along the front-rear direction of the rubber mixing mill body 1, and the front-rear displacement mechanism 3 is parallel to the top of the gantry frame 201. This facilitates the arrangement of the material release mechanism 7, ensuring that the material release mechanism 7 is at a certain height above the roller 102, while also leaving space for the installation of other devices, such as a rubber baffle and an automatic rubber turning mechanism, which can cooperate with the overall device. The specific height and length are not limited and can be adaptively adjusted according to the overall device layout.

[0021] Based on Embodiment 2, as a more preferred Embodiment 2, each of the two bottom ends of the gantry frame 201 is provided with a first base 202. The first base 202 is detachably fixed to the top of the machine body 101 via fasteners. Several first reinforcing ribs 203 are provided around the bottom end of the gantry frame 201 between the two bottom ends and the corresponding first bases 202. This ensures the overall strength of the gantry frame 201 and improves the stability of the installation.

[0022] In a preferred embodiment 4, one of the two front-to-back displacement mechanisms 3 is a conventional slide rail 301, and the other is a first electric slide rail 302. Both the conventional slide rail 301 and the first electric slide rail 302 have first sliders 303 slidably fitted on them. The first sliders 303 on the first electric slide rail 302 are linked to the first electric slide rail 302. The two first sliders 303 are connected by the same connecting plate 4, and both ends of the connecting plate 4 are concealedly fixed to the tops of the corresponding first sliders 303 via concealed fasteners. If concealed fixing screws are used, the surface of the fixing end of the connecting plate 4 is kept flat, facilitating the installation of the axial displacement mechanism 5. The first electric slide rail 302 provides driving force, causing the first sliders 303 to slide in the front-to-back direction. The first sliders 303 slide synchronously through the connecting plate 4.

[0023] Preferably, the first electric slide rail 302 can be a motor-driven lead screw electric slide rail, in which the motor drives the first slider 303 to slide along the slide rail via the lead screw.

[0024] Preferably, the bottom of the first electric slide rail 302 is fixedly engaged with the top of the corresponding gantry frame 201 by a number of fasteners.

[0025] In a preferred embodiment 5, the axial displacement mechanism 5 includes a second electric slide rail 501, on which a second slider 502 is slidably fitted. The second slider 502 and the second electric slide rail 501 are linked together. Sensing mechanisms 6 are respectively arranged at both ends of the second electric slide rail 501, and a material release mechanism 7 is detachably fixedly installed on the top of the second slider 502. The second slider 502 slides through the second electric slide rail 501, causing the material release mechanism 7 to slide axially. Under the sensing control of the sensing mechanisms 6, the material release mechanism 7 reciprocates.

[0026] Preferably, the second electric slide rail 501 can be a motor-driven lead screw electric slide rail, in which the motor drives the second slider 502 to slide along the slide rail via the lead screw.

[0027] In a preferred embodiment 6, the sensing mechanisms 6 are arranged opposite each other, and the sensing ends of the sensing mechanisms 6 all point towards the material release mechanism 7 along the axial direction of the roller 102. This ensures the direction and accuracy of distance monitoring.

[0028] In a more preferred embodiment 7, each of the sensing mechanisms 6 includes a sensor mounting base 601, on which a displacement sensor 602 is detachably mounted.

[0029] Preferably, an existing sensor mounting base 601 and laser displacement sensor can be used. The sensor mounting base 601 has an L-shaped structure, with one right-angled side arranged horizontally and fastened to the top of the limiting plate at the end of the second electric slide rail 501 by fasteners, and the other side arranged vertically and equipped with a laser displacement sensor.

[0030] In a preferred embodiment 8, the material release mechanism 7 includes a fixed bracket 701, on which a material storage tank 702 is detachably fixed. The material storage tank 702 is located away from the axial displacement mechanism 5 via the fixed bracket 701. A discharge port 703 is located at the bottom of the material storage tank 702, and a solenoid valve 704 is installed at the discharge port 703. The solenoid valve 704 is opened via the control cabinet 103 to discharge material, and the discharge speed is controlled by the valve.

[0031] As a more preferred embodiment 9, the solenoid valve 704 is a conventional weighing solenoid valve. This further enables quantitative or batch discharge, simultaneously tracking the material output. When the required output is reached, the valve is closed via the control cabinet 103, completing the quantitative discharge for that batch. This allows for multiple feedings after a single feeding, or multiple quantitative additions during a single rubber mixing process, improving applicability and selectivity.

[0032] As a more preferred embodiment 10, the fixed bracket 701 includes a vertically arranged vertical frame 7012. The bottom of the vertical frame 7012 is fixed to the moving end of the axial displacement mechanism 5 through a second base 7011. An upper ring frame 7013 and a lower ring frame 7014 are respectively provided on the same side of the vertical frame 7012. The upper ring frame 7013 is coaxially located above the lower ring frame 7014. The material storage tank 702 is embedded in the upper ring frame 7013, and the bottom of the material storage tank 702 is supported on the lower ring frame 7014. The outer wall of the material storage tank 702 is detachably fixed to the upper ring frame 7013 by fasteners.

[0033] The upper ring frame 7013 and the lower ring frame 7014 form an "F" shape with the vertical frame 7012. Both the upper ring frame 7013 and the lower ring frame 7014 extend outward in the horizontal direction through connecting rods and are fixedly connected to the vertical frame 7012 through connecting rods. The second base 7011 is fixedly installed on the top of the second slider 502 by fasteners to ensure the fixed installation of the material storage tank 702 and to keep the discharge port 703 of the material storage tank 702 away from the axial displacement mechanism 5, so as to avoid the material release from conflicting with the axial displacement mechanism 5.

[0034] No specific size limit is imposed on the entire material release mechanism 7. In actual use, a fixed bracket 701 and a material storage tank 702 of appropriate size are selected, and a suitable solenoid valve 704 is installed.

[0035] Preferably, a plurality of second reinforcing ribs 7015 are provided around the bottom of the vertical frame 7012 and the second base 7011 to ensure the vertical fixation strength of the vertical frame 7012.

[0036] In a more preferred embodiment 11, a tray 8 is provided directly below the roller 102. The tray 8 serves two purposes: firstly, to receive materials that have not been completely mixed with the colloid or have fallen off; and secondly, to prevent the colloid from falling to the ground.

[0037] The working principle of this utility model: Before use, the material release mechanism 7 stays at the front end of the rubber mixing mill body 1. At this time, the staff can add materials to the material release mechanism 7 while away from the roller 102. The auxiliary materials in the rubber mixing process are weighed and added, such as desulfurizers, catalysts, etc. When in use, the front and rear displacement mechanism 3 is activated by the control cabinet 103 to move the material release mechanism 7 to a suitable position. If the discharge port of the material release mechanism 7 is above the top of the roller 102 on the front side, it can be moved closer to the middle position. After moving to a suitable position, the front and rear displacement mechanism 3 is braked to suspend the material release mechanism 7. Next, the left return distance 'a' and the right return distance 'b' are set via control cabinet 103, and reciprocating feeding is started. The axial displacement mechanism 5 is activated, and the suspended material release mechanism 7 feeds material axially above the top of the roller 102. When the material release mechanism 7 moves to the left, the sensing mechanism 6 on the left side monitors the distance in real time. When the monitored distance reaches the set distance a, the axial displacement mechanism 5 is controlled to reverse through the control cabinet 103, so that the material release mechanism 7 moves to the right. When the material release mechanism 7 moves to the right, the sensing mechanism 6 on the right side monitors the distance in real time. When the monitored distance reaches the set distance b, the axial displacement mechanism 5 is controlled to reverse through the control cabinet 103, so that the material release mechanism 7 moves to the left. Repeat the above process to achieve reciprocating motion. During the process, the material release mechanism 7 continuously feeds materials until feeding is completed. After feeding is completed, the operator closes the axial displacement mechanism 5 and the material release mechanism 7 through the control cabinet 103, and starts the front and rear displacement mechanism 3 to move the material release mechanism 7 forward until it reaches the front end of the rubber mixing mill 1, waiting for the next feeding.
