A color master batch processing slitting device

Abstract

This utility model discloses a color masterbatch processing and slitting device, including an L-shaped bracket, on which a slitting component and a wiping component are mounted. The slitting component includes a geared motor, a pair of guide rails, a guide block, a blade holder, a cutter, a crank, and a connecting rod. The geared motor is fixed to the horizontal section of the L-shaped bracket by a motor mounting plate, and a shock-absorbing rubber pad is placed between the motor mounting plate and the bracket to reduce vibration. The slitting component drives the crank-connecting rod mechanism via the geared motor, causing the cutter to reciprocate along the guide rails to achieve cutting. The wiping component uses spring pressure to keep a sponge filled with anti-sticking liquid continuously attached to the cutter surface, effectively preventing the color masterbatch strips from sticking together. This device has a compact structure, high cutting accuracy, and convenient maintenance, and is suitable for efficient slitting operations in color masterbatch production.

Description

Technical Field

[0001] This utility model relates to the technical field of color masterbatch processing equipment, specifically a color masterbatch processing and slitting device with anti-adhesion function. Background Technology

[0002] In the production of color masterbatch, the extruded masterbatch strips need to be cut into granules by a slitting device. However, existing slitting devices have significant drawbacks: during the cutting process, the masterbatch strips easily adhere to the cutter surface due to frictional heat or the inherent stickiness of the material, leading to decreased cutting efficiency, uneven particle size, and even damage to the cutter. Common solutions include simply increasing the cutting pressure or manual cleaning, but the former may exacerbate adhesion, while the latter is inefficient and unsustainable. Furthermore, existing devices generally suffer from inconvenient cutter adjustment and complex cleaning mechanism designs, making it difficult to meet the high-efficiency requirements of industrial production. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a color masterbatch processing and slitting device. By integrating an automatic wiping component, it solves the problem of cutter adhesion, improves cutting accuracy and efficiency, and optimizes the mechanical structure to enhance stability and durability.

[0004] A color masterbatch processing and slitting device includes an L-shaped bracket, on which a slitting assembly and a wiping assembly are mounted. The slitting assembly includes a geared motor, a pair of guide rails, a guide block, a cutter holder, a cutter, a crank, and a connecting rod. The geared motor is fixed to the horizontal section of the L-shaped bracket via a motor mounting plate, and a shock-absorbing rubber pad is placed between the motor mounting plate and the bracket to reduce vibration. The guide rails are vertically fixed to the vertical section of the bracket, and the guide block engages with the guide rail via a wear-resistant slider with a T-shaped groove for stable sliding. The cutter holder is fixed to the guide block, and its mounting slot allows for detachable fixing of the cutter via a positioning boss and bolts, facilitating replacement. The geared motor drives the crank, which in turn drives the cutter holder to move up and down along the guide rails via the connecting rod, forming a reciprocating cutting motion.

[0005] The wiping assembly includes a Y-shaped support, fixed posts, limiting slide cavities, limiting slide plates, springs, push rods, fixing plates, and a sponge. The Y-shaped support is fixed to an L-shaped bracket. Limiting slide cavities are formed on the inner walls of the fixed posts at both ends. The limiting slide plates slide within the cavities, with one end connected to a spring and the other end connected to the fixing plate via a push rod. In its natural state, the spring causes the sponge to move at a velocity of 0.5-1 N / cm². 2 The pressure adheres to the surface of the cutter. The fixing plate has a U-shaped structure and uses elastic clips to clamp the sponge filled with silicone oil or water-based release agent, achieving a continuous supply and stable fixation of the anti-stick liquid.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] Significant anti-adhesion effect: The sponge continuously adheres to the cutter under the action of the spring, and the anti-adhesion liquid reduces the coefficient of friction between the color masterbatch strip and the cutter, effectively preventing adhesion and extending the life of the cutter.

[0008] Improved cutting precision: The crank-connecting rod mechanism drives the cutter to reciprocate, and with the guidance of the guide rail, it ensures a stable cutting process and uniform particle size.

[0009] Easy maintenance: The cutter is detachable and replaceable, and the sponge body can be quickly installed and removed via elastic clips, reducing maintenance costs. Attached Figure Description

[0021] This implementation plan addresses the technical problems existing in the prior art, such as those disclosed in the background section above: "In the production process of color masterbatch, the extruded color masterbatch strips need to be cut into granules by a slitting device.

[0031] Equipment assembly

[0032] Installation of slitting assembly 2: The geared motor 21 is fixed to the horizontal section of the L-shaped bracket 1 via a motor mounting plate, with a shock-absorbing rubber pad embedded between the motor mounting plate and the bracket. The guide rail 22 is vertically installed on the vertical section of the bracket, and the guide block 23 is engaged with the guide rail 22 via a wear-resistant slider. The blade holder 24 is fixed to the guide block 23, and the cutter 241 is installed in the mounting groove of the blade holder 24 via a positioning boss and bolts.

[0033] Wiping assembly 3 installation: Y-shaped support 31 is fixed to L-shaped bracket 1, and limiting slide cavities 33 are opened on the fixing posts 32 on the inner side walls of both ends.

[0034] Working principle

[0035] Slitting process: After the geared motor 21 starts, it drives the knife holder 24 to move up and down along the guide rail 22 through the crank 25 and connecting rod 26. The cutter 241 cuts the color masterbatch strips that are conveyed to the slitting table.

[0036] Automatic cleaning: During the up-and-down movement of the cutter 241, the sponge 37 of the wiping assembly 3 remains in contact with the surface of the cutter 241. The constant pressure provided by the spring 35 causes the sponge 37 to continuously release anti-stick liquid, effectively preventing the color masterbatch strips from sticking together. When the cutter 241 moves upward, the sponge 37 wipes the surface of the cutter; when it moves downward, the sponge 37 automatically returns to its original position under the action of the spring 35, maintaining the contact state.

[0037] Vibration damping and wear-resistant design: The vibration damping rubber pad absorbs the vibration generated by the motor operation, reducing the impact on cutting accuracy; the wear-resistant slider cooperates with the T-shaped groove of the guide rail 22 to reduce friction loss and extend the service life of the equipment.

[0038] Maintenance and operation: When the cutter 241 is worn and needs to be replaced, it can be disassembled by loosening the bolt; when the anti-stick liquid of the sponge 37 is exhausted or aged, open the elastic clip to replace the sponge. The operation is simple.

[0039] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
