Description

Technical Field

[0001] The invention relates to the field of cap band machines, and in particular to a cap band width adjusting device used for the cap band machines. Background Art

[0002] The back of baseball caps and peaked caps usually have a chin strap. The chin strap is designed to be tied to the back of the head to prevent the front of the hat from slipping off. It can also adjust the circumference of the entire hat to ensure that users with different head shapes and circumferences can wear it comfortably.

[0003] In the production process of existing hats, the hat band needs to be sewn at the notch at the rear. Therefore, the two sides of the sheet of fabric are usually folded in half to form a strip, and the fold is ironed to form the hat band to be sewn, and then the hat band is clamped by a corresponding fixture, cut to a suitable length, and finally the sewing process begins.

[0004] The production process of the relevant hats can refer to the Chinese invention patent "Dust Cap Processing Machine" with patent number CN200420003471.X. In the processing machine, it is composed of a feeding mechanism, a folding mechanism, a crown forming mechanism, a positioning mechanism and a cutting mechanism. Among them, the feeding mechanism can input the cloth and the two hat straps into the processing machine respectively, and use the ultrasonic processing method to position the two hat straps on the two sides of the cloth respectively, and fix one end of the two hat straps on the cloth; secondly, the folding mechanism is provided with several folding parts, so that the cloth is folded into a T shape from the side; the ultrasonic processing method of the crown forming mechanism is used to form the appearance of the crown of the cloth folded into a T shape; then the semi-finished product is transported to the positioning mechanism, and the ultrasonic processing method of the positioning mechanism is also used to weld and fix the front and rear sides of the dust cap respectively, and the other ends of the two hat straps can be torn off and positioned on the cloth respectively; finally, a complete but not yet opened dust cap finished product is cut out by the cutting mechanism.

[0005] The above-mentioned processing machine can realize the processing of dust caps, but if a similar process is used to process other types of hats, there are still certain defects. On the one hand, for different types of hats, the width of the hat band is different, and it is difficult to achieve universal matching of the clamps and guide parts of similar hat band machines. Once the processing type of the hat is changed, most of the parts of the machine need to be replaced and the corresponding accessories need to be improved, which is very inconvenient; on the other hand, because the dust cap is relatively soft, the hat band is designed around the edge of the hat opening to form support at the hat mouth, so that the hat has a fixed shape at least at the hat mouth when worn, and it will not be crumpled into a ball. Therefore, during processing, there is no special requirement for the shaping of its thickness direction. For other types of hats, such as baseball caps, the hat band itself is more coordinated with the metal buckle, so there are certain requirements for the thickness of the hat band. Once the hat band fabric is thin, it will lead to insufficient toughness or easy to slip off the buckle.

[0006] The present application is applicable to a cap band width adjustment device of a cap band machine, which is used to process the cap band. Before the cap band undergoes this processing procedure, it is first pre-processed, that is, the two flanges 102 of the sheet fabric 101 are bent toward the middle, such as Figure 1 As shown, the sheet of fabric 101 is bent at two flanges 102 to form a double-layer fabric. After being bent, the corners are ironed to keep the fabric basically in the bent state. Then, a suitable length is cut as needed and the double-layer fabric is sewn. Summary of the invention

[0007] The first technical problem to be solved by the present invention is to provide a cap band width adjusting device for a cap band machine, which can adjust the guide groove width according to different cap band widths, in view of the current status of the prior art.

[0008] The second technical problem to be solved by the present invention is to provide a cap strap width adjustment device for a cap strap machine which can perform synchronous adjustment at both ends of a guide channel in view of the current state of the prior art.

[0009] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a cap strap width adjustment device for a cap strap machine, comprising:

[0010] The frame body has a main plate and a sub-plate extending in the same direction, and the main plate and the sub-plate are both provided with guide grooves extending along their length direction on mutually adjacent side walls, and the two guide grooves are opened opposite to each other and have a gap therebetween to jointly form a guide channel for the double-layer cloth to pass through;

The guide channel can of course be formed in other forms, but in order to ensure that the two side edges of the single-layer cloth can be supported while adjusting the width of the guide channel, the above-mentioned guide groove is preferably adopted. In this way, no matter how the main plate and the auxiliary plate are relatively displaced, each guide groove can support the side edge of the cloth it supports.

[0032] The present invention is further described in detail below with reference to the accompanying drawings.

[0033] like Figures 1 to 10 FIG. 1 is a preferred embodiment of the present invention. In this embodiment, the cap band width adjusting device for a cap band machine comprises a frame 3 and a first driving mechanism 33 .

[0034] The frame 3 has a main plate 31 and a sub-plate 32 extending in the same direction. The main plate 31 and the sub-plate 32 are both provided with guide grooves 3a extending along their own length direction on the adjacent side walls. The two guide grooves 3a are opened opposite to each other and have a gap to form a guide channel 3b for the double-layer cloth to pass through. The power output end of the first driving mechanism 33 is connected to the sub-plate 32 and can drive the sub-plate 32 to approach or move away from the main plate 31, thereby reducing or increasing the gap of the guide channel 3b. Specifically, the main plate 31 and the sub-plate 32 each include two plate bodies 30 arranged side by side. At least one of the two plate bodies 30 has a side edge 301 extending toward the guide channel 3b, and the guide groove 3a is formed between the side edge 301 and the side wall of the other corresponding plate body 30.

[0035] The guide channel 3b in this embodiment can of course be formed in other forms, but in order to ensure that the two side edges of the single-layer cloth can be supported while the width of the guide channel 3b is adjusted, it is preferably formed in the form of the above-mentioned two guide grooves 3a. In this way, no matter how the main board 31 and the sub-board 32 are relatively displaced, each guide groove 3a can support the side edge of the cloth it supports.

[0036] At the same time, the movement of the cloth strip in the guide channel requires a certain driving force, which can usually be achieved by pushing with a push plate or clamping with an upstream clamp. However, in the present embodiment, the hat band width adjustment device is provided with a clamping jaw assembly 81 adjacent to the guide channel 3b. The power output end of the clamping jaw assembly 81 has a pneumatic clamping jaw 811 capable of clamping a single layer of cloth to move it along the guide channel 3b, and also includes a base plate 4. The above-mentioned clamping jaw assembly 81 also includes a guide rail 812. The guide rail 812 is provided on the base plate 4 and is arranged side by side with the frame 3. The pneumatic clamping jaw 811 is slidably matched with the guide rail 812 and extends toward the base plate 4. In addition, the pneumatic clamp 811 has a pair of claws 813 that can approach each other, and the two claws 813 are distributed on the front and rear sides of the guide channel 3b. In this way, when the pneumatic clamp 811 acts on the single-layer cloth strip, the two claws 813 can rest on the two sides of the cloth strip to achieve the clamping of the cloth strip. Under this premise, the design of the guide channel 3b can just avoid interference with the pneumatic clamp 811, so that the pneumatic clamp 811 can slide smoothly along the guide channel 3b.

[0037] The frame 3 is also arranged on the base plate 4, and a fixing seat 41 is arranged at at least one end of the frame 3, and a slider 42 is arranged on the fixing seat 41 to slide with the fixing seat 41, and the slider 42 is connected to one of the plate bodies 30 of the sub-plate 32. A guide rail 43 is arranged on the fixing seat 41, and a slide groove matching the guide rail 43 is arranged on the slider 42, and the extension direction of the guide rail 43 intersects with the extension direction of the main plate 31 and the sub-plate 32.

[0038] There are two sub-plates 32 in this embodiment, which are arranged on both sides of the main plate 31, and a guide channel 3b is formed between each sub-plate 32 and the main plate 31, and each sub-plate 32 has a set of fixing seats 41 and sliders 42 at both ends. In this way, the design of the sub-plate 32 and the main plate 31 and the movement of the sub-plate 32 relative to the main plate 31 can ensure that the two ends of the sub-plate 32 move synchronously, so that during processing, the width of the processed cloth strips at the head and tail ends can be avoided to the greatest extent.

[0039] Specifically, the base plate 4 is further provided with a transmission assembly 44, which includes a driving rod 441 and a transmission block 442. The driving rod 441 is inserted into the corresponding fixed seat 41, and the transmission block 442 is sleeved on the driving rod 441 and can slide back and forth along the length direction of the driving rod 441 under the rotation of the driving rod 441. The power output end of the first driving mechanism 33 is drivingly connected with the driving rod 441. In this embodiment, the fixed seat 41 has a body 411 and a mounting groove 412 provided on one side of the body 411. The driving rod 441 is inserted into the two side walls of the mounting groove 412. The transmission block 442 is constrained in the mounting groove 412 and can slide along the length direction of the mounting groove 412. Preferably, the transmission assembly 44 also includes a synchronous belt 443 and a synchronous wheel 444. The synchronous wheel 444 is coaxial with the driving rod 441, and the synchronous belt 443 is wound around each synchronous wheel 444 in sequence. In addition, the side of the base plate 4 has a support plate 45 , and an axial hole for the corresponding driving rod 441 to pass through is opened on the support plate 45 . The first driving mechanism 33 is arranged on the support plate 45 and is coaxial with one of the synchronous wheels 444 .

[0040] In addition, the frame 3 is arranged vertically so that its guide channel 3b extends up and down, and the main plate 31 and the auxiliary plate 32 have an avoidance gap 46 for the cutter head to extend into at a position adjacent to the upper part.

[0041] In addition, terms indicating directions, such as "front", "rear", "up", "down", "left", "right", "side", "top", "bottom", etc., are used in the specification and claims of the present invention to describe various exemplary structural parts and elements of the present invention, but these terms are used here only for the purpose of convenience of description and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only used as explanations and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
