DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, purposes and effects achieved by the present application easy to understand, the present application will be further described below in combination with specific embodiments.

[0025] As Figures 1 to 5 shown, the present embodiment provides a novel screw pulling device, which comprises a support base 1, an extruder cylinder 2 is arranged outside the support base 1, a screw body 5 is rotatably arranged inside the extruder cylinder 2, a moving assembly 3 is arranged on the upper end of the support base 1, a fixing assembly 6 is arranged above the moving assembly 3 and located at one end of the outer wall of the screw body 5, the fixing assembly 6 comprises a mounting frame 61, a driving motor 62 is fixedly arranged on the outer wall of the mounting frame 61 and has a bidirectional screw rod 63 fixedly connected to the output end of the driving motor 62, two protruding blocks 64 are threadedly connected to the outer wall of the bidirectional screw rod 63 and are symmetrically arranged at positions, one end of each of the two protruding blocks 64 is fixedly connected to a clamping block 65, and a semihollow groove is formed in the interior of each of the two clamping blocks 65 and is adapted to the diameter of the screw body 5.

[0026] As Figures 3 to 4As shown, the bidirectional screw rod 63 is rotatably installed inside the mounting frame 61, the upper end of each of the two clamping blocks 65 is fixedly provided with a hinge seat 66, the hinge seat 66 is threadedly connected with a bolt 67, the two hinge seats 66 are the same size, four universal wheels are rollingly connected at the four corners of the bottom of the support base 1, two guide rails 7 are fixedly arranged at the upper end of the support base 1, a limiting baffle 4 is fixedly arranged at one end of the guide rail 7, and the outer wall of the limiting baffle 4 is provided with a rubber pad.

[0027] The bidirectional screw rod 63 in the mounting frame 61 is driven by the driving motor 62 to rotate, so that the bidirectional screw rod 63 drives the two clamping blocks 65 to move relative to each other to clamp the screw rod into the semicircular groove, and then the bolt 67 in the hinge seat 66 is rotated to abut the two clamping blocks 65, so that the screw rod is clamped between the two clamping blocks 65, which is convenient for relatively stable pulling out of the screw rod and prevents side slipping from affecting the pulling out operation of the screw rod.

[0028] As shown in Figure 5 The moving assembly 3 comprises a servo motor 32, the servo motor 32 is fixedly installed inside the support base 1, the output end of the servo motor 32 is fixedly connected with a main gear 33, the outer wall of the main gear 33 is meshingly connected with a rack plate 34, the main gear 33 and the rack plate 34 are positionally matched, the outer wall of the rack plate 34 is fixedly installed with a moving plate 31, the rack plate 34 is arranged on the outer wall of the moving plate 31, the bottom of the moving plate 31 is fixedly and symmetrically provided with two sliding blocks 311, the sliding blocks 311 are slidingly connected with the guide rails 7, the upper end of the moving plate 31 is fixedly provided with a positioning seat 36, and the positioning seat 36 is fixedly installed with a hydraulic cylinder 35, and one end of the hydraulic cylinder 35 is connected with the outer wall of the mounting frame 61.

[0029] The screw rod is moved outward by driving the hydraulic cylinder 35 on the positioning seat 36, and then the servo motor 32 is started, the output shaft of the servo motor 32 drives the main gear 33 to rotate, the main gear 33 drives the rack plate 34 to mesh, thereby driving the moving plate 31 to slide on the guide rails 7, and stably moving the screw rod out of the extruder cylinder 2. A sponge pad is arranged between the two guide rails 7, and the sponge pad is arranged on the support base 1. When the screw rod is moved out, the bottom will knock against the support base 1. The sponge pad greatly reduces the bearing capacity of the screw rod, facilitates protection of the screw rod, and buffers one end of the moving plate 31 during movement by the rubber pad on the limiting baffle 4.

[0030] The working principle and process of this utility model are as follows: First, move the support base 1 to a suitable position next to the screw extruder using the universal wheels, and lock the universal wheels using the brake device. Based on the screw diameter, connect the external power supply. Turn on the drive motor 62 to rotate the bidirectional lead screw 63 inside the mounting bracket 61. This causes the bidirectional lead screw 63 to move relative to the clamping blocks 65 on the two protrusions 64, clamping the screw into the semi-circular groove and fixing it in place. Then, rotate the bolt 67 on the hinge seat 66 to bring the two clamping blocks 65 into contact, clamping the screw between the two clamping blocks 65. This ensures relative stability when the screw is pulled out, preventing lateral slippage. The screw pulling operation is affected. After the screw is fixed, the hydraulic cylinder 35 on the drive positioning seat 36 moves the screw outward. Then, the servo motor 32 is started. The output shaft of the servo motor 32 drives the main gear 33 to rotate. The main gear 33 drives the rack plate 34 to mesh, thereby driving the moving plate 31 to slide on the guide rail 7, stably moving the screw out of the extruder barrel 2. A sponge pad is set between the two guide rails 7 to prevent bumps when the screw is moved out. At the same time, the moving plate 31 is cushioned by the rubber pad on the limit baffle 4 when it moves, which facilitates the automatic pulling out and maintenance of the screw and greatly reduces manual operation.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components.
