Description

Technical Field

[0001] This utility model relates to the field of thin films, and more specifically, to a thin film slitting blade assembly. Background Technology

[0002] In the field of film processing, film slitting machines are common equipment. These machines typically include a film slitting blade assembly to cut wide films into multiple narrow strips. Traditional film slitting blade assemblies usually consist of multiple blades arranged along a blade axis, with the spacing between the blades determining the width of the slit film. In practical applications, because different products have different film width requirements, the blade spacing needs frequent adjustment.

[0003] Currently, most film slitting blade assemblies use an independent adjustment method for the blade heads, meaning each blade head is fixed to the blade shaft by a separate locking mechanism. When it is necessary to adjust the blade head spacing, the operator must loosen the locking device of each blade head one by one, manually adjust it to the target position, and then relock it. Although this adjustment method allows for flexible adjustment of the blade head spacing, when multiple blade heads need to be equidistantly arrayed, the operator must measure and calibrate the position of each blade head individually. The adjustment process is cumbersome and time-consuming, affecting production efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a film slitting knife assembly.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a film slitting knife assembly, including a bracket and a plurality of cutter heads slidably connected to the bracket, a scissor arm assembly is provided below the bracket, and the plurality of cutter heads are respectively hinged at each intersection point of the scissor arm assembly.

[0006] The present invention is further configured such that the blade head is detachably connected to the bracket and the scissor arm assembly.

[0007] The present invention is further configured such that: two clamping strips are detachably connected to the top surface of the bracket, the two clamping strips are respectively embedded in the opposite side walls of the cutter head, and the cutter head slides between the two clamping strips.

[0008] The present invention is further configured such that the clamping bar and the cutting head are in planar contact.

[0009] The present invention is further configured such that: a fixing member and a sliding member are respectively hinged to both ends of the scissor arm assembly, the fixing member is fixedly connected to one end of the bracket, and the sliding member is slidably connected to the bracket.

[0010] The present invention is further configured such that: the scissor arm assembly includes a plurality of first rods and a plurality of second rods that are hinged to each other, the first rods are located above the second rods, and the bottom surfaces of both ends of the first rods are fixedly connected with hinge protrusions.

[0011] The present invention is further configured such that: the cutter head includes a connecting post and a blade located at the bottom of the connecting post, and the cross-section of the blade is a semi-circle with the arc facing downward.

[0012] In summary, the present invention has the following beneficial effects: the scissor arm assembly restricts the arrangement of the cutter heads to an equidistant array, and only requires limiting and fixing any two points on the scissor arm assembly to complete the fixing of all cutter heads, thereby improving production efficiency. The fixing component fixes one end of the scissor arm assembly, meaning that only the position of the sliding component needs to be fixed each time an adjustment is made, further improving efficiency.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] Example: A film slitting blade assembly, such as Figure 1 , Figure 2 As shown, it includes a bracket 1 and several blades slidably connected to the bracket 1. A scissor arm assembly is provided below the bracket 1, and the several blades are respectively hinged at each intersection point of the scissor arm assembly.

[0018] Specifically, this embodiment only shows a scheme with three cutter heads, but in actual use, the number of cutter heads can be further increased according to needs. The principle is the same: a sliding groove is provided through the bracket 1, the top of the cutter head slides in the sliding groove, and the bottom of the cutter head is used to cut the film. The scissor arm assembly consists of a first rod 5, a second rod 6, and short rods located at both ends of the scissor arm assembly. All first rods 5 are parallel to each other, and all second rods 6 are parallel to each other. Circular holes for hinged connection of the cutter heads are opened at the intersection of the first rods 5 and the second rods 6. The scissor arm assembly restricts the arrangement of the cutter heads to an equidistant array, and only requires limiting and fixing any two points on the scissor arm assembly to complete the fixing of all cutter heads, thereby improving production efficiency.

[0019] like Figure 1 , Figure 2 As shown, the cutter head is detachably connected to the bracket 1 and the scissor arm assembly. Two clamping strips 2 are detachably connected to the top surface of the bracket 1. The two clamping strips 2 are respectively embedded in the opposite side walls of the cutter head. The cutter head slides between the two clamping strips 2. The clamping strips 2 and the cutter head are in planar contact. The cutter head includes a connecting post 8 and a blade 9 located at the bottom of the connecting post 8. The cross-section of the blade 9 is a semi-circle with the arc facing downward.

[0020] Specifically, slots are provided on both sides of the top sidewall of the connecting column 8. The two clamping strips 2 are integrally formed, forming a U-shaped structure. The clamping strips 2 are detachably connected to the bracket 1 by bolts. The connecting column 8 passes through the first rod 5, the second rod 6, and the bracket 1 from bottom to top. At this time, the slots are located above the bracket 1, allowing the two clamping strips 2 to pass through the slots on all the connecting columns 8, thereby restricting the movement of the connecting column 8 in the vertical direction. At the same time, since the rubber strip and the connecting column 8 are in planar contact, the rotation of the cutter head is also restricted, thus fixing the cutter head. When the cutter head needs to be replaced, the clamping strips 2 can be removed to remove the cutter head, which is convenient for the replacement and maintenance of the cutter head. The blade 9 is symmetrical in the cutting direction to prevent unnecessary workload caused by the mis-clamping of the cutter head.

[0021] like Figure 1 , Figure 2 As shown, the two ends of the scissor arm assembly are respectively hinged with a fixing member 3 and a sliding member 4. The fixing member 3 is fixedly connected to one end of the bracket 1, and the sliding member 4 is slidably connected to the bracket 1. The scissor arm assembly includes a number of first rods 5 and a number of second rods 6 that are hinged to each other. The first rods 5 are located above the second rods 6, and the bottom surfaces of both ends of the first rods 5 are fixedly connected with hinge protrusions 7.

[0022] Specifically, the scissor arm assembly has two intersecting short rods at both ends. At one end of the scissor arm assembly, the two short rods are hinged to a first rod 5 and a second rod 6, respectively, and both short rods are also hinged to a fixing member 3. The fixing member 3 and the sliding groove are located on the same straight line. At the other end of the scissor arm, the two short rods are hinged to a sliding member 4. The fixing member 3 fixes one end of the scissor arm assembly, meaning that only the position of the sliding member 4 needs to be fixed each time an adjustment is made, further improving efficiency. The top of the sliding member 4 is threaded with a fastener. By tightening the fastener, the friction between the bottom of the sliding member 4 and the bracket 1 can be increased, locking the movement of the sliding member 4. The hinge of the first rod 5 and the second rod 6 is achieved through a hinge protrusion 7. The hinge protrusion 7 is integrally formed below the first rod 5, so that the top surface of the first rod 5 remains flat. That is, the scissor arm assembly and the bracket 1 are offset in the vertical direction, avoiding collision between the scissor arm assembly and the bracket 1.

All technical solutions falling within the scope of this utility model's concept are protected.
