DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example 1

[0018] See also Figures 1 to 4, which is the first embodiment of the utility model, and this embodiment provides a technical solution: a plastic part edge cutting mechanism, comprising a cutting table 1, a positioning seat 2 and a cross-cutting structure 3, two cross-cutting structures 3 are symmetrically arranged on the top of the cutting table 1, the positioning seat 2 is arranged between the two cross-cutting structures 3, and a plastic part 4 is placed on the top of the positioning seat 2, and the two ends of the plastic part 4 extend to the two sides of the positioning seat 2 respectively, and the cross-cutting structure 3 comprises a side seat 31, a cylinder 32, a movable plate 33 and a cutter 34, the side seat 31 is fixed to the top surface of the cutting table 1, the cylinder 32 is installed on one side of the side seat 31, the piston rod of the cylinder 32 passes through the other side of the side seat 31 and is installed with a movable plate 33, and the surface of the movable plate 33 is installed with a cutter 34 aligned with the end edge of the plastic part 4, and then The start of the subsequent cylinder 32 will drive the movable plate 33 to move the cutter 34 toward the end edge of the plastic part 4, so that the cutter 34 can cut the end edge of the plastic part 4. A middle hole for the positioning seat 2 to pass through is penetrated at the center of the cutting table 1, and the bottom end of the positioning seat 2 passes through the bottom of the cutting table 1, so that the subsequent positioning seat 2 can move up and down for height adjustment. An adjustment structure is arranged between the cutting table 1 and the positioning seat 2. The adjustment structure includes a side pull seat 51, a support clamping rod 55 and a clamping hole 54. Side through holes 11 for the support clamping rod 55 to pass through are opened on both side surfaces of the cutting table 1. A plurality of clamping holes 54 corresponding to the support clamping rod 55 are penetrated on the surface of the positioning seat 2. A support clamping rod 55 is movably penetrated in the side through hole 11, and the inner end of the support clamping rod 55 passes through By passing through one of the clamping holes 54, the positioning seat 2 can be stably supported and limited. The outer end of the supporting clamping rod 55 passes through the side of the cutting table 1 and is welded and fixed with a side pull seat 51. Subsequently, the supporting clamping rod 55 only needs to be pulled sideways through the side pull seat 51 to move the supporting clamping rod 55 out of the clamping hole 54, and the height of the positioning seat 2 can be slid up and down. The adjustment structure also includes a reset structure, which is arranged between the supporting clamping rod 55 and the side through-hole 11. The reset structure includes a side sliding cavity 56, a side slider 57 and a reset tension spring 58. The side sliding cavity 56 is opened on the upper wall of the side through-hole 11. A side slider 57 is movably installed in the side sliding cavity 56 through the reset tension spring 58. The bottom end of the side slider 57 is fixedly connected to the supporting clamping rod 55, so that the supporting clamping rod 55 will carry the side slider when it moves sideways. 57 stretches the reset spring 58. When the operator subsequently releases the side pull seat 51, the supporting clamping rod 55 will be reset and rebound into the clamping hole 54 under the pull of the reset spring 58. If the height of the positioning seat 2 is to be adjusted subsequently, it is only necessary to pull the side pull seat 51 sideways, so that the supporting clamping rod 55 moves sideways and stretches the reset spring 58 with the side slider 57 until the supporting clamping rod 55 moves out of the clamping hole 54, and the limit on the positioning seat 2 can be released. At this time, the positioning seat 2 can be moved up and down to adjust the height. When it is adjusted to a suitable height, the side pull seat 51 is released, so that the supporting clamping rod 55 rebounds and resets with the side slider 57 under the pull of the reset spring 58, causing the inner end of the supporting clamping rod 55 to be clamped into the clamping hole 54 at other positions, and the stable limit of the positioning seat 2 after the height adjustment can be achieved.

[0019] Among them, a cylindrical groove is opened on the inner wall of one side of the side sliding cavity 56, one end of the reset spring 58 is fixed in the cylindrical groove, and the other end of the reset spring 58 is fixed to the side of the side sliding block 57 to ensure the installation stability of the reset spring 58.

[0020] The bottom surface of the plastic part 4 is provided with a positioning block 41 , and the top surface of the positioning seat 2 is provided with a positioning groove 21 corresponding to the positioning block 41 , so that the plastic part 4 will not be easily displaced when placed on the top of the positioning seat 2 .

[0021] Example 2

[0022] See also Figures 1 to 5 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that when the operator adjusts the height of the positioning seat 2, the support clamping rod 55 in the side-pull state can be auxiliary supported, freeing the operator's hands and further improving the convenience during adjustment.

[0023] Specifically, the adjustment structure also includes an auxiliary structure, which is arranged between the cutting table 1 and the supporting clamping rod 55. The auxiliary structure includes a base 52 fixed on the bottom surface of the cutting table 1, and an auxiliary clamping strip 53 is rotatably installed on the side of the base 52 through a rotating shaft. The bottom surface of the supporting clamping rod 55 is provided with an auxiliary clamping groove 59 corresponding to the auxiliary clamping strip 53. When the operator pulls the side pull seat 51 sideways to move the supporting clamping rod 55 sideways, the auxiliary clamping groove 59 will also move to the outside of the cutting table 1. At this time, the auxiliary clamping strip 53 is rotated upward so that the end of the auxiliary clamping strip 53 is screwed into the auxiliary clamping groove 59. The auxiliary clamping strip 53 can prevent the supporting clamping rod 55 from rebounding, which brings convenience to the operator to adjust the height of the positioning seat 2, freeing the operator's hands, and there is no need to hold the side pull seat 51 with hands during the height adjustment of the positioning seat 2.

[0024] Among them, a rubber seat 591 is embedded and installed on the inner wall of one side of the auxiliary card slot 59, and a circular protrusion 592 is arranged on the surface of the rubber seat 591. The circular protrusion 592 and the rubber seat 591 are an integrated structure, and both are made of rubber material. When squeezed, they will undergo elastic deformation. A circular card slot 531 corresponding to the circular protrusion 592 is opened on the surface of one side of the auxiliary card strip 53, so that after the end of the auxiliary card strip 53 is subsequently screwed into the auxiliary card slot 59, the circular protrusion 592 will be squeezed into the circular card slot 531, thereby realizing auxiliary limiting of the auxiliary card strip 53, ensuring that the auxiliary card strip 53 can be stably in the auxiliary card slot 59 to assist in supporting the supporting card rod 55.

[0025] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
