Description

Technical Field

[0001] The utility model is applicable to the technical field of non-woven fabric processing, and particularly relates to a non-woven fabric cutting device. Background Technique

[0002] At present, a non-woven fabric cutting device is a device used for cutting and processing non-woven fabrics, mainly used in the production and processing of non-woven fabrics. With the increasingly wide application of non-woven fabrics, the production demand for non-woven fabrics has gradually increased.

[0003] However, when using a cutting mechanism to cut and process non-woven fabrics nowadays, after the cutting knife is vertically driven to contact the non-woven fabric, it is cut and processed. During this process, the operator often presses both ends of the whole non-woven fabric to prevent it from shaking randomly during cutting, which may cause wrinkles in the fabric and affect the cutting quality. Such an operation process requires too much labor consumption, and it is very easy to cause insufficient pressing and leveling quality of the fabric due to the operator's mistakes, which affects the cutting cooling. Therefore, we propose a non-woven fabric cutting device. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a non-woven fabric cutting device, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A non-woven fabric cutting device includes a storage frame. A hollow frame is installed on the inner side of the storage frame. A cutting knife is slidably inserted at the bottom of the hollow frame. Sliding plates are slidably installed on the surfaces of both ends of the outer side of the hollow frame.

[0007] At both ends of the side of each sliding plate, fixing plates are hinged through a rotating shaft. Between the sides of every two groups of fixing plates, an I-shaped rod is rotatably installed through a bearing. At the middle end surface of each I-shaped rod, a pressing roller is fixedly sleeved, and the bottom surface of the pressing roller is movably attached to the inner side wall of the storage frame.

[0008] A lifting plate is slidably installed inside the hollow frame. A transmission plate is vertically fixedly installed on the middle end surface of the top of the lifting plate. Reciprocating motors are fixedly installed on the surfaces of both ends of the top of the hollow frame. The bottom of the transmission shaft of the reciprocating motor is fixedly connected to the top surface of the transmission plate. At both ends of the outer side of each lifting plate, fixing blocks are fixedly installed, and the side of the fixing frame is fixedly connected to the outer side of the lifting plate.

[0009] By adopting the above technical scheme, the extrusion roller is rotatably installed on the side of the fixed plate through the I-shaped rod, and the lifting plate and the sliding plate are transmission-connected in combination with the fixed block, thereby ensuring that the bottom of the extrusion roller can always fit the surface of the cloth to be cut inside the containing frame, and the cloth surface is always extruded and leveled, which reduces the labor consumption required for manual leveling and avoids the cloth from wrinkling arbitrarily during cutting, thereby affecting the cutting quality.

[0010] As an optional solution of the technical solution of the present application, sliding grooves are provided inside both ends of the side of the fixing frame, and the fixing blocks are slidably inserted into the sliding grooves.

[0011] By adopting the above technical solution, the rationality of the movement of the entire sliding plate is ensured by the guiding sliding action of the sliding groove on the fixed block.

[0012] As an optional solution of the technical solution of the present application, a fixing frame is fixedly installed on the surface of one end of the top of the containing frame away from the hollow frame, an adjusting bolt is screwed through the middle end of the top of the fixing frame via a thread, and an extrusion plate is installed at the bottom of the adjusting bolt via a bearing.

[0013] By adopting the above technical solution, the vertical movement of the extrusion plate is rationally adjusted by adjusting the bolts to ensure that the bottom of the extrusion plate can be attached to the surface of the dust-free cloth to reinforce it.

[0014] As an optional solution of the technical solution of the present application, guide rods are vertically fixedly installed on the surfaces of both ends of the top of the extrusion plate, guide grooves are opened at both ends of the top of the fixed frame, and the guide rods are slidably inserted into the guide grooves.

[0015] By adopting the above technical solution, the vertical movement stability of the extrusion plate is ensured by the guiding sliding action of the guide groove on the guide rod.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. A dust-free cloth cutting device according to the technical solution of the present application is provided with fixed blocks at both ends of a lifting plate inside a hollow frame, so that when the reciprocating motor is running and drives the lifting plate and the cutting knife to move vertically, under the transmission action of the fixed block, the sliding plates at both ends of the outer side of the hollow frame can be driven to move vertically synchronously. After the fixed plate and the extrusion roller are hinged to the outer side of the sliding plate in combination with the rotating shaft, the sliding plate and the extrusion roller can rotate relatively while moving vertically, thereby ensuring that the bottom of the extrusion roller can always fit the surface of the cloth to be cut inside the containing frame, and the cloth surface is always squeezed and leveled, which reduces the labor consumption required for manual leveling and avoids the cloth from wrinkling arbitrarily during cutting, thereby affecting the cutting quality.

[0018] 2. A dust-free cloth cutting device for the technical solution of this application. By arranging a fixed frame on the top of the storage frame and arranging a vertically movable pressing plate inside the fixed frame through an adjusting bolt, after turning the adjusting bolt, the pressing plate can be driven to move vertically. After it contacts the surface of the dust-free cloth to be cut inside the storage frame, the side end of the dust-free cloth is squeezed and limited to prevent it from moving randomly during cutting and affecting the cutting quality.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] As Figures 1-3 shown, the present utility model provides a technical solution: a dust-free cloth cutting device. One end surface of the top of the storage frame 1 away from the hollow frame 11 is fixedly installed with a fixed frame 3. The middle end of the top of the fixed frame 3 is screwed through with an adjusting bolt 31, and the bottom of the adjusting bolt 31 is installed with a pressing plate 32 through a bearing.

[0024] In this technical solution (as shown by Figure 1 , Figure 2 and Figure 3 ), both ends of the top surface of the pressing plate 32 are vertically fixedly installed with guide rods 33. Both ends of the top of the fixed frame 3 are provided with guide grooves 34, and the guide rods 33 are slidably inserted into the guide grooves 34.

[0025] In this technical solution (as shown by Figure 1 , Figure 2 and Figure 3As shown, a hollow frame 11 is installed on the inner side of the side of the containing frame 1. A cutting knife 12 is slidably inserted at the bottom of the hollow frame 11. Sliding plates 2 are slidably installed on the surfaces at both ends of the outer side of the hollow frame 11. Reciprocating motors 24 are fixedly installed on the surfaces at both ends of the top of the hollow frame 11. The bottom of the transmission shaft of the reciprocating motor 24 is fixedly connected to the top surface of the transmission plate 25.

[0026] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a lifting plate 26 is slidably installed inside the hollow frame 11. A transmission plate 25 is vertically fixedly installed on the middle end surface of the top of the lifting plate 26. Fixed blocks 27 are fixedly installed on the surfaces at both ends of the outer side of each lifting plate 26. The side of the fixed frame 3 is fixedly connected to the outer side of the lifting plate 26. Sliding grooves 28 are opened at both ends inside the side of the fixed frame 3. The fixed blocks 27 are slidably inserted into the inside of the sliding grooves 28.

[0027] In some technical solutions (through Figure 1 , Figure 2 and Figure 3 As shown), fixing plates 21 are hinged to the surfaces at both ends of the side of each sliding plate 2 through rotating shafts. An I-shaped rod 22 is rotatably installed between the sides of every two groups of fixing plates 21 through bearings. An extrusion roller 23 is fixedly sleeved on the middle end surface of each I-shaped rod 22. The bottom surface of the extrusion roller 23 is movably attached to the inner side wall of the containing frame 1.

[0028] During operation, after placing the dust-free fabric to be cut and processed inside the containing frame 1 so that the dust-free fabric is located below the pressing plate 32, the sliding plate 2, the extrusion roller 23, and the cutting knife 12, turn the adjusting bolt 31. Under the guiding and sliding action of the guiding groove 34 on the guiding rod 33, drive the pressing plate 32 to synchronously descend vertically and fit onto the surface of the dust-free fabric to be cut, and then perform the extrusion and fixing treatment on one end of the dust-free fabric. Then, turn on the reciprocating motor 24 through an external control switch, and make it operate. Under the driving action of the transmission plate 25, drive the lifting plate 26 to perform vertical reciprocating movement synchronously inside the hollow frame 11, and then drive the cutting knife 12 below the lifting plate 26 to move vertically to cut the dust-free fabric. Then, under the driving action of the fixed block 27, drive the sliding plates 2 on both sides outside the hollow frame 11 to perform vertical reciprocating movement synchronously. Combined with the structural setting of the fixing plate 21, the bottom of the extrusion roller 23 located on the side of the sliding plate 2 can always fit onto the surface of the dust-free fabric to perform the extrusion and leveling treatment on its surface, avoiding the wrinkles of the dust-free fabric and affecting the cutting quality.
