Description

Technical Field

[0001] The utility model relates to the technical field of cloth cutting, and more specifically to a cloth positioning and cutting device for hat production. Background Art

[0002] Fabric cutting is a very important process in the production and processing of hats. Generally, the rolled fabric is cut into sections according to certain length specifications.

[0003] The existing cloth cutting device lacks a positioning structure, and the size error of the cut product is large. When cutting, the cloth is easily offset due to uneven force, resulting in uneven cuts. In addition, the cut cloth is separated from the raw cloth. Due to the lack of an active unloading structure, it is generally unloaded manually and the segmented cloth segments are sorted, which is a cumbersome operation.

[0004] Therefore, we propose a cloth positioning and cutting device for hat production to address the above problems. Utility Model Content

[0005] The utility model aims to solve the existing practical problems. Compared with the existing technology, a cloth positioning and cutting device for hat production is provided. By adding two groups of positioning components distributed left and right and moving horizontally separately on the cutting table, when the cloth is pulled out from the winding roller, the positioning component far away from the side of the laser cutting head is used to preliminarily position the cloth port. After the preliminary positioning, the cloth is pulled out to a suitable length by the cooperation of the group of positioning components and the electric guide rail 2. At this time, the end of the cloth close to the laser cutting head is limited by the cooperation of another group of positioning components and the electric guide rail 2, which is convenient for cutting and positioning. After the laser cutting head performs laser cutting on the cloth, the cut cloth segment is driven by the lifting structure to pass through the hollow cavity toward one side of the collection box, and then the two groups of electric guide rails are started to move in opposite directions, so that the two groups of positioning components move in opposite directions and separate from the cloth segment, thereby realizing automatic unloading of the cloth segment.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A cloth positioning and cutting device for hat production comprises a cutting table, one end of which is fixedly mounted with a winding roller for winding the cloth, a motorized guide rail 1 fixedly mounted on the cutting table is provided near the winding roller, and a laser cutting head moving in a front-rear horizontal direction is mounted on the motorized guide rail 1;

[0008] A hollow cavity is provided at the upper end of the cutting table and is arranged adjacent to the laser cutting head. A U-shaped frame is fixedly installed at the hollow cavity through a lifting structure. Electric guide rails 2 are fixedly installed on the inner end walls on both the front and rear sides of the U-shaped frame. Positioning components for positioning and clamping the cloth and staggered on the left and right are distributed on a pair of the electric guide rails. A collection box is placed below the hollow cavity of the cutting table.

[0009] Furthermore, the lifting structure is provided with a group and distributed on both sides of the upper end of the hollow cavity. The lifting structure includes a U-shaped frame fixedly connected to the cutting table, and the top ends of the U-shaped frame in the front and rear directions are fixedly connected to two electric push rods. A pair of telescopic ends of the two electric push rods pass through the U-shaped frame and are fixedly connected to the upper end of the U-shaped frame.

[0010] Furthermore, the positioning assembly includes a lower positioning plate fixed on the electric slider of the electric guide rail, and the upper end of the electric slider is also fixedly connected to a bracket, and the top of the bracket is fixedly connected to an upper positioning plate located above the lower positioning plate through an electric push rod.

[0011] Furthermore, a pair of lower positioning plates are arranged flush with the upper end surface of the cutting table, and the length of the lower positioning plates is greater than the width of the cloth.

[0012] Furthermore, the height of the pair of electric push rods does not exceed the top height of the U-shaped frame.

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] (1) This solution adds two groups of positioning components that are distributed left and right and move horizontally independently on the cutting table. When the cloth is pulled out from the winding roller, the positioning component on the side away from the laser cutting head is used to perform preliminary positioning on the cloth port. After the preliminary positioning, the cloth is pulled out to a suitable length by using the cooperation of this group of positioning components and the electric guide rail 2. At this time, another group of positioning components is used in cooperation with the electric guide rail 2 to limit the end of the cloth close to the laser cutting head to facilitate cutting positioning. After the laser cutting head performs laser cutting on the cloth, the cut cloth segment is driven by the lifting structure to pass through the hollow cavity toward the side of the collection box, and then the two groups of electric guide rails 2 are started to move in opposite directions, so that the two groups of positioning components move in opposite directions and detach from the cloth segment, thereby realizing automatic unloading of the cloth segment.

[0015] (2) The positioning assembly in the present invention is composed of a lower positioning plate and an upper positioning plate that can move up and down. The lower positioning plate is arranged flush with the upper end surface of the cutting table. After the cloth is pulled out, it covers the lower positioning plate. Then, the electric push rod is used to drive the upper positioning plate downward to achieve the upper and lower clamping and positioning of the cloth. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will combine the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments in the utility model belong to the scope of protection of the utility model.

[0025] Embodiment 1:

[0026] The utility model discloses a cloth positioning and cutting device for hat production, see Figure 1 , comprising a cutting table 1, a winding roller 2 for winding up the cloth 11 is fixedly installed at one end of the cutting table 1, an electric guide rail 3 fixedly installed on the cutting table 1 is provided near the winding roller 2, a laser cutting head 4 moving in a front-rear horizontal direction is installed on the electric guide rail 3, and a guide roller for pulling and guiding the cloth 11 is provided between the winding roller 2 and the electric guide rail 3;

[0027] A hollow cavity is provided at the upper end of the cutting table 1 and is arranged near the laser cutting head 4. A U-shaped frame 5 is installed in the hollow cavity. Electric guide rails 6 are fixedly installed on the inner end walls on both the front and rear sides of the U-shaped frame 5. Positioning components 7 for positioning and clamping the cloth 11 and staggered on the left and right are distributed on the pair of electric guide rails 6.

[0028] For details, please refer to Figure 2 The positioning assembly 7 includes a lower positioning plate 71 fixed on the electric slide block of the electric guide rail 26, and a bracket 72 is fixedly connected to the upper end of the electric slide block. The upper end of the bracket 72 is fixedly connected to an upper positioning plate 74 located above the lower positioning plate 71 through an electric push rod 1 73. A pair of lower positioning plates 71 are arranged flush with the upper end surface of the cutting table 1, and the length of the lower positioning plates 71 is greater than the width of the cloth 11;

[0029] The two positioning components 7 are independently driven horizontally by two electric guide rails 6. In the initial state, please refer to Figure 1 , two groups of positioning components 7 are arranged near one side of the laser cutting head 4, and a space for the cloth 11 to pass through is reserved between the two upper positioning plates 74 and the lower positioning plate 71. When cutting, one end of the cloth 11 is pulled outward and stretched, and the end of the cloth 11 passes through the guide roller, and the two groups of positioning components 7 extend outward. At this time, the electric push rod 1 73 located on the outside is first driven, and the upper positioning plate 74 is pressed down and limited to the upper end surface of the cloth 11. The upper positioning plate 74 cooperates with the lower positioning plate 71 to realize the positioning of the outer end of the cloth 11, and then the electric guide rail 2 6 cooperates with the positioning component 7 to pull the cloth 11 outward to a suitable length;

[0030] See also Figure 3 , Figure 4 , and then use another electric guide rail 2 6 to move another group of positioning components 7 to a suitable distance away from the laser cutting head 4, so as to facilitate the laser cutting head 4 to cut the inner end of the cloth 11 that is limited in the horizontal direction. When the lower positioning plate 71 located on the inner side moves to a suitable distance, the upper positioning plate 74 is pressed down by the electric push rod 1 73 to limit one side of the cut end of the laser cutting head 4. After both ends of the cloth 11 are limited, the electric guide rail 3 is used to move the laser cutting head 4 horizontally to achieve cutting of the cloth 11. During the cutting process, the cloth is not easily offset due to uneven force.

[0031] Embodiment 2:

[0032] On the basis of the embodiment 1, this embodiment adds 5 fixedly mounted with a pair of 6 at the hollow cavity, and a lifting structure for lifting 5 up and down is installed on 1 to facilitate automatic unloading and boxing of the cut cloth segments, specifically:

[0033] See also Figure 4 - Figure 6 A U-shaped frame 5 is fixedly installed at the hollow cavity through a lifting structure. The lifting structure is provided with a group and distributed on both sides of the upper end of the hollow cavity. The lifting structure includes a U-shaped frame 8 fixedly connected to the cutting table 1. The top of the U-shaped frame 8 in the front and rear directions is fixedly connected to an electric push rod 9. The telescopic ends of a pair of electric push rods 9 pass through the U-shaped frame 8 and are fixedly connected to the upper end of the U-shaped frame 5. The cutting table 1 is located below the hollow cavity and a collection box 10 is placed. The height of the pair of electric push rods 73 does not exceed the top height of the U-shaped frame 8, and the width of the collection box 10 is greater than the width of the U-shaped frame 5.

[0034] After the cloth 11 is laser cut by the laser cutting head 4, the cut cloth segments are limited by the two sets of positioning components 7. At this time, the U-shaped frame 5 is moved toward the inside of the collection box 10 by the two sets of electric push rods 2 9. When the cloth segment drops to a suitable height of the collection box 10, the upper positioning plate 74 is lifted outward by the two sets of electric push rods 1 73, and the upper positioning plate 74 is separated from the upper end surface of the cloth segment. Then the two sets of electric guide rails 2 6 are started to move in opposite directions, so that the two sets of positioning components 7 move in opposite directions and separate from the cloth segment, thereby realizing automatic unloading of the cloth segment. This reciprocating process allows the cut cloth segments to be laid layer by layer in the collection box 10 without the need for manual unloading and sorting.

[0035] The working process and principle of the utility model are as follows:

[0036] When cutting, one end of the cloth 11 is pulled outward and stretched to pass through the two sets of positioning components 7. At this time, the electric push rod 1 73 located on the outside is driven first, and the upper positioning plate 74 is pressed down to limit the upper end surface of the cloth 11. The upper positioning plate 74 cooperates with the lower positioning plate 71 to achieve the positioning of the outer end of the cloth 11. Then, the electric guide rail 2 6 cooperates with the positioning component 7 to pull the cloth 11 outward to a suitable length, and then another set of positioning components 7 is used to limit the inner end of the cloth 11 in the same way.

[0037] After both ends of the cloth 11 are limited, the electric guide rail 3 is used to drive the laser cutting head 4 to perform horizontal laser cutting on the cloth 11, and the cut cloth segments are positioned by two sets of positioning components 7;

[0038] During the unloading process, the lifting structure is used to drive the two groups of positioning components 7 and the cloth segment to move toward the collection box 10. After the cloth segment descends to a suitable height of the collection box 10, the two groups of electric push rods 1 73 are used to lift the upper positioning plate 74 outward, and the upper positioning plate 74 is separated from the upper end surface of the cloth segment. Then the two groups of electric guide rails 2 6 are started to move in opposite directions, so that the two groups of positioning components 7 move in opposite directions and separate from the cloth segment, and the cloth segment falls into the collection box 10. This reciprocating process allows the cut cloth segments to be laid layer by layer in the collection box 10 without the need for manual unloading and sorting.

[0039] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the utility model according to the technical solution and improved ideas of the utility model, which should be included in the protection scope of the utility model.
