Abstract

This utility model discloses a chain clamp anti-vibration device for a film transverse stretching machine, comprising: a positioning block connected to the chain; and a structure and connection relationship of the positioning block, slider, guide rail, elastic adaptive component, and rigid guide component, which can effectively alleviate the impact and vibration problem when the chain clamp passes through the track joint. The positioning block is connected to the chain, and the slider is fixed to one side of the positioning block and slidably connected to the guide rail. This structure provides basic movement guidance for the chain clamp. The elastic adaptive component is connected between the top of the slider and the chain clamp. When the guide wheel of the slider passes through the guide rail joint and generates an instantaneous impact, the elastic adaptive component can absorb the impact energy using its own elastic characteristics. The rigid guide component is connected to the top of the chain clamp, which can further constrain and guide the movement direction of the chain clamp, ensuring that the chain clamp always maintains the correct movement trajectory during transverse stretching, thereby improving the quality stability of the film product.

Description

Technical Field

[0001] This utility model relates to the field of film stretching technology, specifically to a chain clamp anti-vibration device for a film transverse stretching machine. Background Technology

[0002] In the film production process, transverse stretching is the core process that determines the mechanical properties, thickness uniformity and optical characteristics of the film. The transverse stretching machine clamps the edge of the film with a chain clamp device and stretches it from narrow width to wide width along the transverse guide rail, so that the molecular chains are oriented in the transverse direction, thereby improving the tensile strength, impact resistance and light transmittance of the film.

[0003] However, in the existing technology, the operational stability of the chain clamp is easily affected by the characteristics of the guide rail structure, especially the impact problem at the guide rail joint. When the guide wheel or support wheel of the chain clamp passes through the joint, it will generate an instantaneous impact, causing the chain clamp to vibrate, which will cause the film to slip and result in uneven stretching. Therefore, we need to propose a chain clamp anti-vibration device for the film transverse stretching machine. Utility Model Content

By setting a positioning block connected to the chain, a slider connected to the positioning block and slidably connected to the guide rail, an elastic adaptive component connecting the slider and the chain clamp, and a rigid guide component connected to the top of the chain clamp, the impact vibration of the chain clamp can be greatly reduced and the stretching stability can be improved, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The chain clamp anti-vibration device of the film transverse stretching machine includes: a positioning block connected to the chain, a slider fixedly connected to one side of the block, and the slider being slidably connected to the guide rail;

[0007] An elastic adaptive component, the bottom of which is connected to the top of the slider, and the top of the elastic adaptive component is connected to a chain clamp for holding the film.

[0008] A rigid guide assembly, the bottom of which is connected to the top of the chain clamp.

[0010] Preferably, the elastic element is a stainless steel spring, and the bottom end of the elastic element is fixedly connected to the inner bottom of the positioning shell.

[0011] Preferably, the rigid guide assembly includes a connecting post, the bottom end of which is fixedly connected to the top of the chain clamp, and a collar is fixedly connected to the top of the connecting post, with a slide rod slidably connected inside the collar.

[0012] Preferably, the inner wall of the collar is provided with a plurality of sets of balls, and the plurality of sets of balls are arranged in a ring array.

[0013] Preferably, the outer wall of the slide bar is fixedly connected at equal intervals with several sets of reinforcing members to prevent it from bending due to vertical shear stress.

[0014] Preferably, the connection between the reinforcing member and the slide rod is made of a reinforced stainless steel plate, and the collar is provided with a relief groove to allow the reinforcing member to pass smoothly.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention, through the rational arrangement of the structure and connection relationship of the positioning block, slider, guide rail, elastic adaptive component, and rigid guide component, effectively alleviates the impact and chatter problem when the chain clamp passes through the track joint, significantly improving the stability of the film's lateral stretching process. The positioning block is connected to the chain, and the slider is fixed to one side of the positioning block and slidably connected to the guide rail. This structure provides basic movement guidance for the chain clamp, ensuring stable operation along the track. The elastic adaptive component is connected between the top of the slider and the chain clamp. When the guide wheel of the slider experiences a momentary impact as it passes through the guide rail joint, the elastic adaptive component can absorb the impact energy using its own elastic properties, reducing the transmission of the impact to the chain clamp. At the same time, the rigid guide component is connected to the top of the chain clamp, which can further constrain and guide the movement direction of the chain clamp, preventing the chain clamp from deviating due to chatter and ensuring that the chain clamp always maintains the correct movement trajectory during the lateral stretching process, thereby improving the quality stability of the film product.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] The anti-vibration device of the chain clamp in the transverse stretching machine mainly includes: a positioning block 1, an elastic adaptive component 4, and a rigid guide component 6 connected to the chain; a slider 2 is fixedly connected to one side of the positioning block 1, and the slider 2 is slidably connected to the guide rail 3; the bottom end of the elastic adaptive component 4 is connected to the top of the slider 2, and the top end of the elastic adaptive component 4 is connected to a chain clamp 5 for holding the film; the bottom end of the rigid guide component 6 is connected to the top of the chain clamp 5. By setting the connection structure of the positioning block 1, slider 2, guide rail 3, elastic adaptive component 4, and rigid guide component 6, stable support and guidance are provided for the chain clamp 5, laying the foundation for the subsequent anti-vibration function.

[0025] The elastic adaptive component 4 includes a positioning shell 401, the bottom end of which is fixedly connected to the top of the slider 2. A movable rod 402 is slidably inserted inside the positioning shell 401. The top end of the movable rod 402 is fixedly connected to the bottom of the chain clamp 5. An elastic element 403 is fixedly connected to the bottom end of the movable rod 402. By setting the elastic adaptive component 4, which consists of the positioning shell 401, the movable rod 402, and the elastic element 403, the movable rod 402 can move flexibly within the positioning shell 401, providing structural support for the elastic element 403 to play a buffering role.

[0026] The elastic element 403 is set as a stainless steel spring. The bottom end of the elastic element 403 is fixedly connected to the inner bottom of the positioning shell 401. By setting the stainless steel spring as the elastic element 403, the good elasticity and corrosion resistance are utilized to effectively absorb the impact energy when the chain clamp 5 is impacted, thereby reducing the flutter effect.

[0027] The rigid guide assembly 6 includes a connecting post 601, the bottom end of which is fixedly connected to the top of the chain clamp 5, and a collar 602 is fixedly connected to the top of the connecting post 601. A slide rod 603 is slidably connected inside the collar 602. By setting the rigid guide assembly 6 composed of the connecting post 601, the collar 602 and the slide rod 603, the movement direction of the chain clamp 5 is further constrained, and the running stability of the chain clamp 5 is enhanced.

[0028] The inner wall of the collar 602 is fitted with several sets of balls 604 arranged in a circular array. By setting the balls 604 in a circular array, the friction between the collar 602 and the slide bar 603 is reduced, making the collar 602 slide more smoothly on the slide bar 603 and reducing the additional vibration caused by friction.

[0029] The connecting post 601 is made of high-strength alloy steel, possessing high rigidity and toughness. Its bottom end is fixedly connected to the top of the chain clamp 5 by bolts. Anti-slip pads are provided at the connection point to enhance the stability of the connection. The top end is fixed to the collar 602 by welding to ensure a firm connection. The collar 602 is an annular structure made of wear-resistant cast iron, with its inner diameter slightly larger than the outer diameter of the slide rod 603. An annular groove is formed on its inner wall to hold the balls 604. The slide rod 603 is made of high-strength chrome-plated round steel, and its surface is precision ground to achieve high smoothness and straightness, ensuring smooth sliding of the collar 602. The balls 604 are made of high-carbon chromium bearing steel, possessing extremely high hardness and wear resistance. Several groups of balls 604 are evenly arranged in an annular array within the annular groove on the inner wall of the collar 602. The balls 604 can rotate flexibly within the groove, and some spherical surfaces protrude from the inner wall of the collar 602, contacting the outer wall of the slide rod 603.

[0030] The outer wall of the slide rod 603 is fixedly connected with several sets of reinforcing members 8 at equal intervals to prevent it from bending due to vertical shear stress. By setting the reinforcing members 8 at equal intervals, the structural strength of the slide rod 603 is enhanced, the slide rod 603 is prevented from bending due to vertical shear stress, and the rigid guide assembly 6 is guaranteed to work normally.

[0031] The connection between the reinforcing member 8 and the slide rod 603 is made of a reinforced stainless steel plate. The collar 602 is provided with a relief groove 7 to allow the reinforcing member 8 to pass smoothly. By setting the reinforced stainless steel plate and the relief groove 7, the firmness of the connection between the reinforcing member 8 and the slide rod 603 is enhanced, while ensuring that the collar 602 can pass smoothly through the reinforcing member 8 without affecting the normal operation of the rigid guide assembly 6.

[0032] The reinforcing member 8 is a sheet-like structure, or it can be made of alloy steel plate. It is fixedly connected to the outer wall of the slide bar 603 at equal intervals. The width and depth of the clearance groove 7 are slightly larger than the thickness and height of the reinforcing member 8, ensuring that the collar 602 can smoothly pass through the reinforcing member 8 when sliding on the slide bar 603. By setting up such a rigid guide assembly 6 consisting of the connecting post 601, the collar 602, and the slide bar 603, the movement direction of the chain clamp 5 is further constrained, and the running stability of the chain clamp 5 is enhanced. Both the slide bar 603 and the reinforcing member 8 can be fixedly connected to the film stretching production line.

[0033] Working principle: When the chain clamp 5 experiences a momentary impact as it passes through the track joint, the stainless steel elastic element 403 in the elastic adaptive component 4 undergoes elastic deformation due to the impact, absorbing the impact energy and reducing the impact on the chain clamp 5; the collar 602 in the rigid guide component 6 slides along the slide bar 603, cooperating with the ball bearing 604 to reduce friction, and the reinforcing element 8 enhances the strength of the slide bar 603, ensuring the stability of the chain clamp 5's movement direction and preventing deviation; the coordinated action of each component, through the combination of elastic buffering and rigid guidance, effectively reduces the chatter of the chain clamp 5, prevents film slippage, and ensures uniform film stretching.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
