Description

Technical Field

[0001] The utility model belongs to the technical field of rubber production, and particularly relates to an open mill for rubber production. Background Art

[0002] Rubber is an elastic material mainly composed of high molecular polymers. It is usually made of natural rubber or synthetic rubber. Rubber plays an important role in industrial production and daily life, and its application range is very wide.

[0003] In the existing open mill for rubber production, the rubber to be kneaded is placed between two kneading rollers, and the kneading of the rubber is achieved by the opposite rotation of the two kneading rollers. After using for a certain period of time, the operator needs to hold a scraper to clean the residual rubber on the outer arc surface of the kneading rollers. This process is time-consuming and laborious, bringing a great working burden to the staff. Summary of the Utility Model

[0004] In view of this, aiming at the deficiencies of the existing technology, the utility model provides an open mill for rubber production, which can stably support the scraper for cleaning through the triangular supports on the left and right sides, facilitating the use by the operator.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is: an open mill for rubber production, including a workbench. Four corners of the lower surface of the workbench are respectively provided with supporting feet. Two symmetrically distributed mounting boxes are arranged on the upper surface of the workbench. Two front-back symmetrically distributed guiding sliding grooves are respectively opened on the opposite inner sides of the two mounting boxes. Sliding seats are respectively and slidably arranged inside the guiding sliding grooves. Kneading rollers are rotatably arranged between two adjacent sliding seats on the left and right. Motors II are respectively arranged on the left sides of the two sliding seats on the left. The output shafts of the motors II are respectively fixed to the adjacent kneading rollers through couplings. An electric drive module for driving the sliding seats to move is further arranged on the mounting boxes. A cleaning module for cleaning the kneading rollers is further arranged between the mounting boxes; the electric drive module includes a bidirectional lead screw I rotatably arranged on the upper sides inside the two mounting boxes. The sliding seats are respectively in threaded connection with the adjacent bidirectional lead screw I. Motors I are respectively arranged at the upper ends of the rear sides of the two mounting boxes. The output shafts of the motors I are respectively fixed to the adjacent bidirectional lead screw I through couplings.

[0006] As a further improvement of the present utility model, the cleaning module includes sliding grooves symmetrically formed on the front and rear sides of the opposite inner sides of the two mounting boxes. A sliding frame is slidably arranged among the four sliding grooves. Two scrapers symmetrically distributed front and rear are arranged on the upper surface of the sliding frame. An electric driving unit for driving the scrapers to lift is also arranged on the mounting box. The electric driving unit includes guide rails welded and fixed on the lower sides inside the two mounting boxes. Two adjusting blocks symmetrically distributed front and rear are slidably arranged on the outer arc surfaces of the guide rails. Rotating frames are rotatably arranged at the upper ends of the adjusting blocks. The sides of the rotating frames away from the adjusting blocks are rotatably connected to the sliding frame. A driving assembly for driving the adjusting blocks to move is also arranged on the mounting box. The driving assembly includes a two-way lead screw two rotatably arranged on the lower sides inside the two mounting boxes. The adjusting blocks are respectively threadedly connected to the adjacent two-way lead screw two. Motors three are arranged at the lower ends of the rear sides of the two mounting boxes. The output shafts of the motors three are fixedly connected to the adjacent two-way lead screw two through couplings respectively.

[0007] As a further improvement of the present utility model, a control panel is arranged on the front side of the mounting box. The motor one, the motor two and the motor three are all electrically connected to the control panel.

[0008] As a further improvement of the present utility model, two door panels symmetrically distributed left and right are rotatably arranged on the front side of the workbench. Handles are arranged on the front sides of the door panels.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] Firstly, by controlling the two motors one to run synchronously through the control panel, the sliding seats on the front and rear sides are driven to move closer to each other, and then the open mill rolls on the front and rear sides are driven to quickly and stably adjust the distance between the two open mill rolls.

[0011] Secondly, the control panel controls the two motors one to run, so that the adjusting blocks on the front and rear sides drive the sliding frame to rise through the rotating frames, and then the sliding frame drives the scraper to rise and contact the open mill roll, so as to clean the rotating open mill roll.

[0012] Thirdly, during the cleaning process, since a triangle can be formed between two adjacent adjusting blocks, two adjacent rotating frames and the sliding frame before and after, the scraper can be stably supported by the triangular supports on the left and right sides for cleaning.

[0013] Fourthly, during daily production and processing, personnel can open the door panel by pulling the handle, and then use the internal space of the workbench to place and take tools as needed. Description of the Drawings

Second motors 110 are provided on the left sides of the two sliding seats 106 on the left. The output shafts of the second motors 110 are respectively fixed to the adjacent kneading rollers 107 through couplings. An electric drive module for driving the sliding seats 106 to move is further provided on the installation boxes 104. A cleaning module for cleaning the kneading rollers 107 is further provided between the installation boxes 104.

[0022] As Figure 1 , 2As shown in FIGS. 3, the electric drive module includes a first bidirectional lead screw 108 rotatably arranged on the upper side inside two mounting boxes 104. The sliding seats 106 are respectively threadedly connected to the adjacent first bidirectional lead screws 108. At the upper rear ends of the two mounting boxes 104, a first motor 109 is provided respectively, and the output shafts of the first motors 109 are fixedly connected to the adjacent first bidirectional lead screws 108 through couplings.

[0023] As Figure 2 , 3 As shown in FIGS. 4, the cleaning module includes sliding grooves 201 symmetrically formed on the front and rear sides of the opposite inner sides of the two mounting boxes 104. A sliding frame 202 is slidably arranged among the four sliding grooves 201. On the upper surface of the sliding frame 202, two scrapers 203 are symmetrically distributed front and rear. An electric drive unit for driving the scrapers 203 to lift is further provided on the mounting box 104; the electric drive unit includes guide rails 204 welded and fixed to the lower sides inside the two mounting boxes 104. On the outer arc surfaces of the guide rails 204, two adjusting blocks 205 are symmetrically distributed front and rear and are slidably arranged. At the upper ends of the adjusting blocks 205, rotating frames 206 are rotatably arranged respectively. The sides of the rotating frames 206 far from the adjusting blocks 205 are respectively rotatably connected to the sliding frame 202. A drive assembly for driving the adjusting blocks 205 to move is further provided on the mounting box 104; the drive assembly includes a second bidirectional lead screw 207 rotatably arranged on the lower sides inside the two mounting boxes 104. The adjusting blocks 205 are respectively threadedly connected to the adjacent second bidirectional lead screws 207. At the lower rear ends of the two mounting boxes 104, a third motor 208 is provided respectively, and the output shafts of the third motors 208 are fixedly connected to the adjacent second bidirectional lead screws 207 through couplings.

[0024] As Figure 1 , 2 As shown in FIGS. 4, a control panel 301 is provided on the front side of the mounting box 104. The first motor 109, the second motor 110 and the third motor 208 are all electrically connected to the control panel 301.

[0025] When it is necessary to knead rubber, the operator adjusts the two first motors 109 to run synchronously through the control panel 301, so that the output shafts of the two first motors 109 respectively drive the first bidirectional lead screws 108 connected thereto to rotate. Through the threaded relationship between the first bidirectional lead screws 108 and the sliding seats 106, the sliding seats 106 on the front and rear sides are driven to approach each other, and then the kneading rollers 107 on the front and rear sides are driven to quickly and stably adjust the distance between the two kneading rollers 107.

The rubber to be kneaded is placed between the two kneading rollers 107 to realize the kneading of the rubber.

[0027] After the rubber mixing is completed, the control panel 301 controls the operation of the two first motors 109, so that the first motors 109 drive the mixing rollers 107 on the front and rear sides to be directly above the scraping knives 203. Then, the control panel 301 controls the synchronous operation of the two third motors 208, so that the two third motors 208 respectively drive the bidirectional lead screws 207 connected thereto to rotate, causing the adjusting blocks 205 on the front and rear sides to move closer to each other. During the movement of the adjusting blocks 205, rotation occurs between the adjusting blocks 205 and the rotating frames 206, and rotation occurs between the rotating frames 206 and the sliding frames 202, so that the adjusting blocks 205 on the front and rear sides drive the sliding frames 202 to rise through the rotating frames 206, thereby causing the sliding frames 202 to drive the scraping knives 203 to rise and contact the mixing rollers 107. Then, the control panel 301 controls the operation of the two second motors 110, so that the two mixing rollers 107 rotate, and during the rotation, the outer arc surfaces of the mixing rollers 107 are cleaned by the scraping knives 203.

[0028] According to another embodiment of the present invention, as Figure 1 , 2 , as shown in FIG. 4, two door panels 103 that are symmetrically distributed left and right are rotatably provided on the front side of the workbench 101, and handles are provided on the front sides of the door panels 103.
