Description

Technical Field

[0001] This utility model relates to the technical field of mold cleaning and maintenance equipment, specifically to a mold cleaning and maintenance equipment for film production. Background Technology

[0002] In the production of film, the cleaning and maintenance of molds is crucial, directly affecting the quality and production efficiency of the film products. Currently, the industry widely uses automatic laser mold cleaning machines for mold cleaning and maintenance. However, existing automatic laser mold cleaning machines generally suffer from a significant problem: a lack of effective material fixing functionality. During actual processing, because the material is not securely fixed, it is prone to shaking. This shaking not only leads to decreased processing accuracy and increased product defect rate, resulting in additional processing costs for the user, but also causes frequent abnormal interruptions or repeated calibrations during operation of the automatic laser mold cleaning machine, greatly reducing work efficiency and significantly diminishing its practicality.

[0003] To address the aforementioned issues, a novel automatic laser mold cleaning machine, patent publication number CN215466703U, is disclosed in the prior art. This patent, through innovative design, effectively solves the problem of existing automatic laser mold cleaning machines lacking material fixing capabilities, enabling materials to remain stable during processing. This significantly reduces processing costs for users, substantially improves the working efficiency of the automatic laser mold cleaning machine, and greatly enhances its practicality.

[0004] However, a closer look at the actual operation reveals that this patented solution still has room for improvement. It uses a manual knob to rotate a lever, causing the bushing to move a connecting rod and push / pull a push rod under the action of a threaded structure, thereby fixing the material via a push plate. During this process, the balance plate on the connecting rod simultaneously compresses or stretches the spring. When the knob is manually stopped, the balance plate and the connecting rod as a whole are affected by the spring force, generating a reverse force on the bushing. This reverse force may cause a slight displacement of the bushing, thus changing the fixing position of the push plate on the material, affecting the stability of the material fixation, and even potentially causing the material to shake again, making it impossible to continuously guarantee the stability and accuracy of the processing. Utility Model Content

[0005] To solve the above-mentioned technical problems, a mold cleaning and maintenance device for film production is provided, which solves the problems existing in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a mold cleaning and maintenance equipment for film production, comprising a mold washing machine body and a reinforcement mechanism, wherein the reinforcement mechanism comprises an operation box with an internal cavity fixed to the front center of the mold washing machine body, a pressure plate sliding on the back side of the operation box, and a pusher part disposed in the inner cavity of the operation box;

[0007] The pushing part includes an operating screw disposed in the middle of the inner cavity of the operating box, a movable sleeve threaded onto the body of the operating screw, and a crossbeam fixed to the outer wall of the movable sleeve. The crossbeam is connected to the pressure plate through an intermediate component. A connecting sleeve is also fastened to the body of the crossbeam. A spring is fixed between the connecting sleeve and the inner wall of one side of the operating box. One end of the operating screw is rotatably connected to the inner wall of the operating box, and the other end of the operating screw extends out of the operating box and is connected to a clamping assembly.

[0008] Preferably, the locking assembly includes a knob post fixedly connected to the end of the operating screw and a movable notch formed in the body of the knob post. The body of the knob post is fitted with an internal gear fixedly connected to the side wall of the operating box, and the movable notch contains an elastic latch that cooperates with the internal gear.

[0009] Preferably, the elastic latch includes a positioning block that slides within the movable notch, and a return spring is fixed between one end of the positioning block and the innermost inner wall of the movable notch.

[0010] Preferably, the inner wall of the positioning block is provided with a pressure groove with a right-angled trapezoidal cross-section, and the end of the knob post is provided with a compression screw. One end of the compression screw is threaded into the pressure groove and fixed with a convex ball. The convex ball abuts against the inclined inner wall of the pressure groove.

[0011] Compared with the prior art, the advantages of this utility model are: by setting the clamping component, it can be effectively locked after the rotating rod rotates. This design ensures that the bushing always stays in the predetermined position, and the push plate can also continuously and stably fix the device, which greatly enhances the reliability of the device fixation.

[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0019] Reference Figure 1-4 As shown, a mold cleaning and maintenance device for film production includes a mold washing machine body 1 and a reinforcement mechanism for preventing shaking during material processing.

[0020] The reinforcement mechanism includes an operation box 2 with an internal cavity fixed to the front center of the main body 1 of the mold washing machine, a pressure plate 3 that slides on the back side of the operation box 2, and a pusher part disposed in the inner cavity of the operation box 2.

[0021] The pushing part includes an operating screw 4 located in the middle of the inner cavity of the operating box 2, a movable sleeve 5 threaded onto the body of the operating screw 4, and a cross frame 6 fixed to the outer wall of the movable sleeve 5. The cross frame 6 is connected to the pressure plate 3 through an intermediate component.

[0022] The intermediate component is a push-pull rod 7. One end of the push-pull rod 7 is fixedly sleeved on the body of the cross frame 6, and the other end of the push-pull rod 7 passes through the operation box 2 and is fixedly connected to the pressure plate 3.

[0023] When the operating screw 4 is rotated, the movable screw sleeve 5 can slide along the body of the operating screw 4 under the thread structure. Then, the crossbar 6 is pushed by the push-pull rod 7 to contact the pressure plate 3 and the device placed on the body 1 of the mold washing machine until the device is fixed between the pressure plate 3 and the inner wall of the body 1 of the mold washing machine, thereby fixing the device to be processed.

[0024] Furthermore, referring to Figure 3 As shown, it is worth noting that the crossbar 6 is also tightly fitted with a connecting sleeve 9, and a rectangular sliding frame 8 is slidably fitted on the outside of the connecting sleeve 9. The sliding frame 8 is fixed between the inner walls of the front and rear sides of the operation box 2.

[0025] A spring 10 is fixed between the connecting sleeve 9 and the inner wall of one side of the operation box 2;

[0026] The spring 10 assists the connecting sleeve 9 in its operation and also serves as a reset buffer, preventing the crossbar 6 from vibrating due to friction during movement and reducing the frictional resistance experienced by the crossbar 6 during movement.

[0027] By providing the sliding frame 8 and the connecting sleeve 9, the swaying of the cross frame 6 and the connecting sleeve 9 as a whole during movement can be avoided, and the safety of the machine operation can be improved.

[0028] Furthermore, referring to Figure 4 As shown, it is worth noting that one end of the operating screw 4 is rotatably connected to the inner wall of the operating box 2, and the other end of the operating screw 4 extends out of the operating box 2 and is connected to a clamping assembly;

[0029] The locking assembly effectively locks the rotating rod after it rotates, ensuring that the bushing remains in a fixed position and the push plate can continuously and stably fix the device, greatly enhancing the reliability of the device's fixation.

[0030] Furthermore, referring to Figure 4 As shown, it is worth noting that the locking assembly includes a knob post 11 fixedly connected to the end of the operating screw 4 and a movable notch opened in the body of the knob post 11. The body of the knob post 11 is fitted with an internal gear 13 fixedly connected to the side wall of the operating box 2. The movable notch contains an elastic latch that cooperates with the internal gear 13.

[0031] The elastic latch includes a positioning block 12 that slides within the movable notch, and a return spring 16 is fixed between one end of the positioning block 12 and the innermost inner wall of the movable notch.

[0032] The inner wall of the positioning block 12 is provided with a pressure groove 14 with a cross section in the shape of a right trapezoid. The end of the knob post 11 is provided with a pressing screw 15. One end of the pressing screw 15 is threaded into the pressure groove 14 and a convex ball is fixed thereon. The convex ball abuts against the inclined inner wall of the pressure groove 14.

[0033] The knob and knob column 11 allow for easy manual operation of the operating screw 4 from outside the operating box 2, thereby enabling the push-pull action of the pressure plate 3.

[0034] After the knob column 11 is rotated, simply rotate the knob column 11 to cause the extrusion screw 15 to pass into the pressure groove 14 under the thread structure. The convex ball at the end of the extrusion screw 15 abuts against the inner wall of the pressure groove 14, thus applying extrusion force to the positioning block 12. The positioning block 12 slides out from the movable notch, causing one end of the positioning block 12 to pass between two adjacent teeth of the internal gear 13, thereby locking the knob column 11 and the operating screw 4 as a whole, ensuring the stability of the pressure plate 3 after sliding.

[0035] When the positioning block 12 is pressed and slids, the positioning block 12 can simultaneously stretch and deform the return spring 16. In this way, by utilizing the elastic force of the return spring 16, when the reverse knob presses the screw 15 to reduce the pressure on the positioning block 12, the positioning block 12 can return to its retractable movement notch under the elastic force of the return spring 16, quickly releasing the fixation of the knob post 11 and the operating screw 4 as a whole.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
