Abstract
Description
Technical Field
[0001] This utility model relates to the field of roll film production technology, and in particular to a cutting device for roll film production. Background Technology
[0002] Cutting equipment for roll film production is a key piece of equipment in the roll film processing production line. Its function is to precisely cut continuous roll film into single sheets or products of specific shapes according to preset dimensions.
[0003] The mechanism of the cutting equipment can be referenced from the utility model disclosed in authorization announcement number "CN222115183U" as "a cutting device for producing plastic film". By setting a second electric cylinder, mounting plate and cutting blade, it can cut plastic film. By setting a servo motor, threaded rod and threaded sleeve, it can drive the cutting blade to move back and forth to cut the front and back positions of the plastic film. By setting a first electric cylinder, horizontal plate, vertical rod and pressure plate, it can fix the left and right sides of the plastic film to prevent the plastic film from moving during the cutting process. It solves the problems of existing devices that are not convenient to limit the plastic film during cutting, and the plastic film is relatively loose during cutting and is easily damaged.
[0004] However, the aforementioned limiting position at both ends of the plastic film can easily cause deviation during the movement of the plastic film, which can affect the flatness of the cut edge of the plastic film. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cutting device for roll film production.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A cutting device for roll film production includes a workbench. A cutting unit is provided at the top center of the workbench, and auxiliary components are symmetrically arranged on both sides of the cutting unit on the top of the workbench. The auxiliary components include a fixed frame, an electric telescopic rod is provided at the top of the fixed frame, and a pressure plate is vertically connected to the extended end of the electric telescopic rod. Fixed limit plates are symmetrically fixed on both sides of one end of the pressure plate, and a screw drive assembly is provided inside the other end of the pressure plate. A movable limit assembly is provided inside the pressure plate through the screw drive assembly.
[0008] The movable limiting component and the fixed limiting plate are symmetrically and slidably provided with auxiliary limiting components on both sides of their adjacent surfaces.
[0009] In addition, a preferred structure is that a groove is provided in the pressure plate at the movable limiting component, and a scale line is provided on one side of the pressure plate above the groove, with the starting end of the scale line being "0" and the starting end of the scale line being located on one side of the fixed limiting plate.
[0010] Furthermore, in a preferred configuration, the movable limiting component includes a fixing block, with T-shaped fixing blocks symmetrically installed on both sides of the top of the fixing block, and L-shaped fixing blocks symmetrically installed at both ends of the fixing block, with an identification block installed on the top of the L-shaped fixing block outside the pressure plate.
[0011] In addition, a preferred structure is that the auxiliary limiting component includes an auxiliary limiting plate, a plurality of guide rods are installed at equal intervals on the top of the auxiliary limiting plate, and a spring body is sleeved on the outer wall of the guide rod, and a plurality of limiting sliders are installed at equal intervals on one side of the guide rod.
[0012] In addition, in a preferred structure, the fixed limiting plate and the L-shaped fixing block are provided with a sliding groove on one side at the auxiliary limiting plate and the limiting slider, and the fixed limiting plate and the L-shaped fixing block are provided with a through hole above the sliding groove and at the guide rod.
[0013] In addition, a preferred structure is that the fixed limiting plate and the L-shaped fixing block have a groove located above the slide groove and at the through hole, the height of the groove is less than the height of the through hole, and the cross-sectional area of the groove is greater than the cross-sectional area of the spring body.
[0014] The beneficial effects of this utility model are as follows:
[0015] In this invention, by symmetrically arranging auxiliary components on both sides of the cutting unit, the top of both sides of the cut area of the roll film of different sizes within a certain range can be pressed down, while limiting the two sides. This avoids the offset or shaking caused by the elasticity or tension change of the roll film itself during cutting, and also avoids the roll film from skewing during movement, thus ensuring the stability of the roll film during cutting.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Reference Figure 1-6 A cutting device for roll film production includes a workbench 1, a cutting unit 2 is provided at the top center of the workbench 1, and auxiliary components 3 are symmetrically arranged on both sides of the cutting unit 2 on the top of the workbench 1. The auxiliary components 3 include a fixed frame 31, an electric telescopic rod 32 is provided at the top of the fixed frame 31, and a pressure plate 33 is vertically connected to the top end of the electric telescopic rod 32. Fixed limiting plates 35 are symmetrically fixedly installed on both sides of one end of the pressure plate 33, and a screw drive assembly 38 is provided inside the other end of the pressure plate 33. A movable limiting assembly 34 is provided inside the pressure plate 33 through the screw drive assembly 38. Auxiliary limiting components 36 are symmetrically slidably arranged on both sides of the adjacent surfaces of the movable limiting assembly 34 and the fixed limiting plate 35.
[0025] It is worth noting that the specific structure and working principle of the cutting unit 2 are existing technologies that are already publicly available on the market, and are not part of the main technical problems to be solved in this utility model. Therefore, this utility model will not elaborate on them further.
[0026] Furthermore, the lead screw drive assembly 38 drives the movable limit assembly 34 to perform horizontal linear motion, and the specific structure and working principle of the lead screw drive assembly 38 are all existing technologies that are currently publicly available on the market, so they will not be described in detail.
[0027] Meanwhile, a groove is provided inside the pressure plate 33 at the movable limiting component 34, and a scale line 37 is provided on one side of the pressure plate 33 above the groove. The starting end of the scale line 37 is "0", and the starting end of the scale line 37 is located on one side of the fixed limiting plate 35. By using the marking block in conjunction with the setting of the scale line 37, the distance between the movable limiting component 34 and the fixed limiting plate 35 of the two sets of auxiliary components 2 is ensured to be consistent.
[0028] Meanwhile, the active limiting component 34 includes a fixing block, with T-shaped fixing blocks symmetrically installed on both sides of the top of the fixing block, and L-shaped fixing blocks symmetrically installed at both ends of the fixing block. A marking block 341 is installed on the top of the L-shaped fixing block outside the pressure plate 33.
[0029] Furthermore, the auxiliary limiting component 36 includes an auxiliary limiting plate 361, with multiple guide rods 362 evenly installed on the top of the auxiliary limiting plate 361, and a spring body 364 sleeved on the outer wall of the guide rods 362, with multiple limiting sliders 363 evenly installed on one side of the guide rods 362.
[0030] The spring body 364 ensures that its auxiliary limiting plate 361 always exerts downward force.
[0031] Furthermore, the fixed limiting plate 35 and the L-shaped fixing block are provided with sliding grooves on one side at the auxiliary limiting plate 361 and the limiting slider 363, and the fixed limiting plate 35 and the L-shaped fixing block are provided with through holes above the sliding grooves and at the guide rod 362.
[0032] Furthermore, the fixed limiting plate 35 and the L-shaped fixing block have a groove located above the slide groove and at the through hole. The height of the groove is less than the height of the through hole, and the cross-sectional area of the groove is greater than the cross-sectional area of the spring body 364.
[0033] In this embodiment, the roll of film to be cut is passed through the auxiliary component 2 and the cutting unit 2 in sequence, and the area to be cut is located directly below the cutting unit. One side of the roll of film is then attached to the fixed limiting plate 35. Then, the electric telescopic rod 32 moves the pressing block towards the top of the roll of film and presses it down, so as to avoid deviation or shaking during cutting due to changes in the elasticity or tension of the roll of film itself.
[0034] Then, by controlling the opening of the lead screw drive assembly 38, the lead screw drive assembly 38 drives the movable limit assembly 34 to move towards the fixed limit plate 35 until one side of the auxiliary limit plate 361 of the movable limit assembly 34 is in contact with the roll film. Thus, the fixed limit plate 35 and the auxiliary limit plate 361 of the movable limit assembly 34 limit both sides of the roll film, preventing the roll film from tilting during movement.
[0035] In this invention, by symmetrically arranging auxiliary components 3 on both sides of the cutting unit 2, the top of both sides of the cut area of the roll film of different sizes within a certain range can be pressed down, while limiting the two sides. This avoids the offset or shaking caused by the elasticity or tension change of the roll film itself during cutting, and also avoids the roll film from skewing during movement, thus ensuring the stability of the roll film during cutting.
[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
