DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution for automatic width adjustment equipment: an automatic width adjustment equipment, comprising a workbench 1 and a plurality of groups of conveying rollers 2 installed on one side of the upper end of the workbench 1, a fixed plate 3 is installed on one side of the upper end of the workbench 1 near the rear end of the conveying roller 2, and a movable plate 5 is installed on the other side of the upper end of the workbench 1 corresponding to the fixed plate 3, and a second vertical plate 7 and a first vertical plate 6 corresponding to each other are installed on one side of the upper end of the fixed plate 3 and the movable plate 5, respectively, and the profile can be transmitted by using the plurality of groups of conveying rollers 2, so that it can be transported to the forming roller, so as to facilitate the extrusion forming of the profile;

[0021] The upper end of the workbench 1 is located below the movable plate 5 and is equipped with two slide rails 45. Slide seats 46 corresponding to the two slide rails 45 are installed on both sides of the bottom of the movable plate 5. A double-axis motor 41 is installed on the upper end of the workbench 1 near the outer side of the movable plate 5. The two output ends of the double-axis motor 41 are connected to a transmission rod 42. One end of the two transmission rods 42 is connected to a direction-changing gear box 43. Each direction-changing gear box 43 is connected to a driving screw 44. One end of the driving screw 44 passes through the first vertical plate 6 and is rotatably connected to the second vertical plate 7. Threaded seats 47 are installed on both sides of the bottom end of the first vertical plate 6 corresponding to the two direction-changing gear boxes 43. The threaded seats 47 are threadedly connected to the driving screw 44. The first vertical plate 6 is slidably connected to the slide rail 45 through the slide seat 46. During extrusion molding, if it is necessary to adjust the spacing between the forming rollers on the first vertical plate 6 and the second vertical plate 7, the dual-axis motor 41 can be started to drive the transmission rod 42 to rotate synchronously, and then the transmission of the reversing gear box 43 is used to drive the two driving screws 44 to rotate synchronously (the rotation direction is consistent). As a result, when the driving screw 44 rotates, the threaded seat 47 on the movable plate 5 will move linearly along the surface of the driving screw 44. At the same time, the slide seat 46 at the bottom of the movable plate 5 will also slide along the slide rail 45 to ensure the stability of the movable plate 5 when moving. When the movable plate 5 approaches the fixed plate 3, the forming roller on the first vertical plate 6 will approach the forming roller on the second vertical plate 7, thereby adjusting the spacing between the two corresponding forming rollers. Otherwise, the two forming rollers are moved away from each other.

[0022] A scale plate 48 is installed on the upper surface of the workbench 1 near the slide rail 45, and a scale pointer 49 corresponding to the scale plate 48 is installed at a corner of the upper surface of the movable plate 5. By using the scale pointer 49 on the movable plate 5 to indicate movement on the scale plate 48, it is convenient to understand the distance moved by the movable plate 5 toward the fixed plate 3, that is, the distance the forming roller on the first vertical plate 6 approaches the forming roller on the second vertical plate 7, thereby improving the accuracy of the spacing adjustment between the two forming rollers, that is, the accuracy of the width adjustment between the fixed plate 3 and the movable plate 5.

[0023] The second vertical plate 7 is provided with a plurality of grooves at equal intervals, each of which is slidably mounted with a connecting seat 72. A positioning seat 75 is fixedly arranged at the top of the second vertical plate 7 corresponding to each groove. The top of the connecting seat 72 is connected with an adjusting screw 74 that passes through the second vertical plate 7 and extends to the top of the positioning seat 75. The adjusting screw 74 is threadedly connected to the positioning seat 75, and the bottom end of the adjusting screw 74 is rotatably connected to the top of the connecting seat 72. The middle part of the connecting seat 72 is rotatably connected with a connecting shaft 73, and one end of the connecting shaft 73 is mounted with an upper forming roller. The inner side surface of the second vertical plate 7 is located directly below the upper forming roller and is rotatably connected to the lower forming roller 71. The outer side surface of the second vertical plate 7 is provided with transmission gears corresponding to the upper and lower forming rollers 71. By twisting the adjusting screw 74, the bottom end of the adjusting screw 74 drives the connecting seat 72 to slide up and down in the groove, thereby adjusting the height position of the upper forming roller connected to one end of the connecting shaft 73. In this way, the distance between the upper and lower forming rollers 71 can be adjusted, which is convenient for adapting to the processing of profiles of different sizes.

[0024] The upper forming roller and the lower forming roller 71 on the first vertical plate 6 and the second vertical plate 7 have the same structural design, and the outer side surfaces of the first vertical plate 6 and the second vertical plate 7 are located outside the transmission gear and are equipped with a gear protection cover 4. The number and design positions of the forming rollers on the first vertical plate 6 and the second vertical plate 7 are the same and opposite. Secondly, the other ends of the upper forming roller and the lower forming roller 71 are driven by the transmission gear and the gear chain in conjunction with the motor, and the gear protection cover 4 is to protect the transmission gear and the gear chain.

[0025] The working principle of the utility model is as follows: when in use, the spacing between the forming rollers on the first vertical plate 6 and the second vertical plate 7, that is, the width between the fixed plate 3 and the movable plate 5, can be adjusted according to the size of the processed profile;

[0026] During adjustment, the dual-axis motor 41 is controlled to rotate in the forward direction, so that the driving screw 44 is driven to rotate through the transmission rod 42 and the direction-changing gear box 43. When the driving screw 44 rotates, the moving plate 5 is driven to move linearly on the driving screw 44 through the threaded seat 47. At the same time, the slide seat 46 at the bottom of the moving plate 5 also slides on the slide rail 45, so that the moving plate 5 approaches the fixed plate 3, thereby reducing the distance between the forming rollers on the first vertical plate 6 and the second vertical plate 7 in turn.

[0027] On the contrary, when width adjustment is required, the dual-axis motor 41 is controlled to rotate in the opposite direction, so that the movable plate 5 is moved away from the fixed plate 3, and the first vertical plate 6 is moved away from the second vertical plate 7, so as to increase the distance between the two, that is, increase the distance (width) between the forming rollers on the first vertical plate 6 and the forming rollers on the second vertical plate 7, so as to adapt to the processing of profiles with larger widths;

[0028] In addition, by turning the adjusting screw 74, its bottom end drives the connecting seat 72 to slide up and down in the groove, thereby adjusting the height position of the upper forming roller connected to one end of the connecting shaft 73, thereby adjusting the distance between the upper forming roller and the lower forming roller 71, which is convenient for adapting to the processing of profiles of different sizes.

[0029] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
