Description

Technical Field

[0001] This utility model relates to the field of slitting equipment technology, specifically to a blade holder assembly for a felt roll slitting machine. Background Technology

[0002] The applicant's prior patent 202221326106.7 discloses a blade holder assembly for a felt roll slitting machine. In actual application, we found that the waste generated during felt roll slitting falls into the blade groove of the blade holder. When the blade is replaced later, the waste in the blade groove is not easy to clean, which will cause the locking bolt of the replaced blade to not be fully tightened, resulting in the blade loosening and the risk of cutting deviation or even falling off.

[0003] Therefore, we propose a blade holder assembly for a felt roll slitting machine. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the prior art, this utility model provides a knife holder assembly for a felt roll slitting machine, which overcomes the shortcomings of the prior art, has a reasonable design and compact structure, and solves a series of technical problems caused by the accumulation of waste chips in the knife groove of the knife holder.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A blade holder assembly for a felt roll slitting machine, comprising a fixed base and a first locking bolt, characterized in that:

[0009] The fixing seat has a groove for accommodating the end of the blade. One side wall of the groove protrudes inward to form a support boss. The first locking bolt is a stepped bolt. The first locking bolt passes through the other side wall of the fixing seat and is threadedly connected to the support boss. The blade is pressed and fixed by the cooperation of the support boss and the stepped surface of the first locking bolt.

[0010] The blade holder assembly also includes a fixed cover and a movable cover. The fixed cover has a pair and is respectively located on both sides of the opening of the blade groove (for inserting the blade). There is a gap between the fixed cover and the blade. The movable cover is sleeved on the blade. The movable cover extends to both sides and slides with the fixed cover to cover the gap.

[0011] Furthermore, the movable shielding cover has a lip surrounding the blade, and the lip is in a sealing fit with the blade.

[0012] Furthermore, the fixed cover includes a cover plate body, a plug portion extending from the cover plate body to the inside of the opening of the knife groove, and a fixing piece that fits against the side wall of the fixing seat. The second locking bolt locks and fixes the fixing piece to the side wall of the fixing seat.

[0013] Furthermore, the opening of the blade groove is inclined downwards relative to the blade insertion direction.

[0014] Furthermore, the inner bottom wall of the blade groove is inclined downward.

[0015] (III) Beneficial Effects

[0016] This utility model provides a blade holder assembly for a felt roll slitting machine, which has the following advantages: by using a fixed cover and a movable cover to cover the opening of the blade groove, waste chips generated during slitting are prevented from falling into the blade groove; at the same time, if a single cover is used, the blade vibration during slitting will cause the opening between the cover and the blade to be opened, and waste chips will still fall in. The movable cover can be moved and covered when the blade vibrates, thus improving the reliability of the structure. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] See attached document Figure 1-4 A blade holder assembly for a felt roll slitting machine includes a fixed base 1, a first locking bolt 5, a fixed cover 3, and a movable cover 4.

[0037] The fixing base 1 has a groove 1a for accommodating the end of the blade 2. The inner wall of the groove 1a (the side wall of the fixing base 1 with a flange 1c that is fixed to the blade holder is the inner wall, and the side wall away from the blade holder is the outer wall) has flanges 1c protruding outwards at both its upper and lower ends. Locking bolts lock the flanges 1c to the blade holder to achieve the installation and fixation of the fixing base 1. A supporting boss 1b is formed on the inner wall of the groove 1a, protruding horizontally inwards (specifically towards the outer wall). The first locking bolt... Bolt 5 is a stepped bolt (existing technology, the bolt of the stepped bolt is stepped, the large diameter part of the bolt is smooth, and its small diameter part is threaded). The first locking bolt 5 passes through the outer wall of the fixing seat 1 and is threadedly connected to the support boss 1b. The step surface of the first locking bolt 5 presses the blade 2, and its small diameter part passes through the mounting hole of the blade 2 and is threadedly connected to the mounting hole of the support boss 1b. The blade 2 is pressed and fixed by the cooperation of the support boss 1b and the step surface of the first locking bolt 5.

[0038] The fixed cover 3 has a pair and is respectively located on both sides of the opening of the blade groove 1a. There is a gap D between the fixed cover 3 and the blade 2. The movable cover 4 is sleeved on the blade 2. The movable cover extends to both sides and slides with the fixed cover 3 to cover the gap D.

[0039] In some other embodiments, a horizontal sliding guide structure, such as a sliding guide structure consisting of a T-shaped guide rail and a T-shaped groove, can be provided between the movable shield and the fixed shield or the fixed base to avoid the influence of vibration in other directions of the blade and improve the stability of the sliding of the movable shield.

[0040] In this embodiment, the movable cover 4 is provided with a lip 4a around the blade 2. The lip 4a is sealed to the blade 2. The lip 4a is preferably made of rubber or silicone. It can be fixed to the opening of the blade 2 of the movable cover 4 by vulcanization or adhesive bonding to improve the sealing effect between the movable cover 4 and the blade 2.

[0041] In this embodiment, the fixed cover 3 includes a cover plate body, a plug portion 3b extending from the cover plate body 3a to the inner side of the opening of the knife groove 1a, and a fixing piece 3c that fits against the side wall of the fixing seat 1. The plug portion 3b and the fixing piece 3c are both vertically arranged relative to the cover plate body 3a (specifically, the part that blocks the opening of the knife groove). The second locking bolt locks the fixing piece 3c to the side wall of the fixing seat 1, which facilitates the quick installation and reliable connection of the fixed cover 3.

[0042] In this embodiment, the opening of the blade groove 1a is inclined downward relative to the insertion direction of the blade 2, so that the waste can slide down along the movable shielding cover 4 and the fixed shielding cover 3, reducing the accumulation of waste at the opening of the blade groove 1a.

[0043] In this embodiment, the cutting groove 1a has a through-hole structure at both ends (located at both ends in the insertion direction of the blade 2). The two side walls of the cutting groove 1a are spaced apart from the blade 2. Even if some waste falls into the cutting groove 1a, the waste can be smoothly discharged from the cutting groove 1a under its own gravity and the vibration during cutting. In other embodiments, the inner bottom wall of the cutting groove 1a is inclined downwards, which can further promote the discharge of waste.

[0044] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
