Description

Technical Field

[0001] The utility model relates to the field of bath towel forming machines, in particular to a bath towel forming machine with a length fixing device. Background Art

[0002] Bath towels are a type of towel. Made from pure cotton yarn, they come in two varieties: yarn-woven and thread-woven. Their terry loops are taller and denser than those of face towels and pillowcases, offering superior water absorption, storage, and warmth retention. They are primarily used for wiping and covering the body after bathing, and are also commonly used as a blanket to protect against the cold.

[0003] Some hotels use bath towels with satin trim. During the manufacturing process, it's crucial to ensure the relative positioning of the trim on each cut towel is consistent, preventing variations in the trim from occurring within the same batch. However, due to the inherent elasticity of bath towels, deformation can easily occur during cutting and trimming, leading to skewed trim and poor quality. Conventional bath towel manufacturing equipment struggles to overcome this challenge. Utility Model Content

[0004] The utility model aims to provide a bath towel forming machine with a length-fixing device, so as to solve the problem in the prior art that the decorative part of the bath towel is easily skewed during the cutting process.

[0005] The technical solution of the utility model is: a bath towel forming machine with a length fixing device, comprising a base, wherein the length fixing device comprises a limiting portion and a clamping portion for the bath towel to pass through;

[0006] The bath towel comprises a fleece surface and a decorative satin surface, wherein the fleece surface has a greater friction coefficient and a greater cross-sectional height than the satin surface, and a boundary line is formed between the fleece surface and the satin surface;

[0007] The limiting portion includes a limiting base, on which a limiting pressure plate and a pressure plate driver are provided. The limiting pressure plate is arranged corresponding to the satin surface and is driven by the pressure plate driver to perform lifting motion. An end of the limiting pressure plate away from the clamping portion is arranged to be close to the edge line and the boundary line of the base in a contoured manner.

[0008] The clamping portion includes a clamp and a retraction driver. The clamp includes a first clamp and a second clamp capable of clamping the fleece surface. The retraction driver can drive the clamp to drive the bath towel to move in a direction away from the limiting portion.

[0009] Preferably, brushes are provided at adjacent ends of the first clamp and the second clamp.

[0010] Preferably, the clamp also includes a clamp base arranged perpendicular to the length direction of the bath towel, the first clamp is composed of a plurality of clamping units, any clamping unit is vertically connected to the clamp base through an adjusting member, and the plurality of clamping units are arranged in parallel, and the adjacent end to the second clamp is constructed as a clamping end; the adjusting member is used to adjust the distance between the corresponding clamping ends.

DETAILED DESCRIPTION

[0022] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0023] like Figure 1 As shown, a bath towel forming machine with a fixed length device includes a base 1, a material roll 2 carrying bath towel raw materials is provided at one end of the base 1, and a material taking mechanism 3 for taking the bath towel raw materials out of the material roll 2 is provided at the other end. A cutting device 4 is provided between the material roll 2 and the material taking mechanism 3. The cutting device 4 includes a pair of cutting knives 41 that perform cutting actions in a vertical direction, and are used to cut the bath towel raw materials pulled out by the material taking mechanism 3 into multiple sections of bath towels.

[0024] like Figure 2 As shown, the bath towel described in this application has a pile surface 51 composed of velvet and a decorative satin surface 52 made of silk. After the bath towel is cut, the satin surface 52 must be perpendicular to the length of the bath towel and at the same distance from the cut end. Because the bath towel is made of soft and elastic fabric, the bath towel material removed from the material roll 2 by the material removal mechanism 3 is prone to deformation, and the straightness of the satin surface 52 and the distance from the cut end cannot be guaranteed to meet the requirements.

[0025] Therefore, in the present application, a length fixing device is provided adjacent to the cutting device 4 to solve the above problem.

[0026] The length fixing device includes a limiting portion 6 and a clamping portion 7 .

[0027] Among them, Figure 3 As shown, the limiting unit 6 includes a limiting base 61, mounted with a limiting pressure plate 62 and a pressure plate driver 63. After the retrieving mechanism 3 pulls the bath towel material from the material roll 2, the limiting pressure plate 62 is positioned above the satin surface 52. The pressure plate driver 63 drives the limiting pressure plate 62 to move upward and downward, bringing it into contact with the satin surface 52. In this embodiment, a straight boundary line 53 is formed between the fleece surface 51 and the satin surface 52, and the edge of the limiting pressure plate 62 near the boundary line 53 is contoured to a straight structure.

[0028] like Figure 4As shown, the clamping portion 7 includes a clamp base 71 and a retraction driver 74. A clamp 72 is provided on the clamp base 71. The clamp 72 includes a first clamp 721 and a second clamp 722 that perform a clamping action in the vertical direction. After the material-taking mechanism 3 pulls the bath towel raw material out of the material roll 2, the hairy surface 51 is located between the first clamp 721 and the second clamp 722 and can be clamped by the first clamp 721 and the second clamp 722. A horizontal guide rail is provided on the base 1, and both ends of the clamp base 71 are slidably provided on the horizontal guide rail. One end of the retraction driver 74 is provided on the base 1, and the other end is connected to the clamp base 71. In this embodiment, the retraction driver 74 adopts a cylinder, which can drive the clamp base 71 to move toward or away from the limiting portion 6.

[0029] When using:

[0030] First, the limiting pressure plate 62, driven by the pressure plate driver 63, abuts the satin surface 52, while the first clamp 721 and the second clamp 722 clamp the fleece surface 51. Subsequently, the retraction driver 74 drives the clamp 72 to move the bath towel away from the limiting pressure plate 62. Because the satin surface 52 has a lower coefficient of friction than the fleece surface 51, the satin surface 52 slips against the limiting pressure plate 62 until the edge of the limiting pressure plate 62 near the boundary line 53 abuts the portion on the curved boundary line 53.

[0031] Because the rough surface 51 has a higher cross-sectional height than the satin surface 52, the boundary line 53 generates a greater resistance to the limiting pressure plate 62. This resistance can cause the clamp 72 and the corresponding portion of the rough surface 51 to slip. However, the rough surface 51 corresponding to the boundary line 53 where the limiting pressure plate 62 abuts will continue to be pulled by the clamp 72. This continues until the entire boundary line 53 abuts the edge of the limiting pressure plate 62.

[0032] Because the edge of the limiting plate 62 is designed to be straight, the boundary line 53 will also become straight after the contact is complete, thus making the satin surface 52 straight. At the same time, because the distance between the limiting portion 6 and the cutting device 4 along the length of the bath towel is fixed, the length of each bath towel cut by the cutting device 4 will also be fixed, based on the boundary line 53 of the contact limiting plate 62.

[0033] In addition, in this embodiment, the first clamp 721 is composed of a plurality of clamping units, such as Figure 5 As shown, any clamping unit is vertically connected to the clamp base 71 through an adjusting member 73, and multiple clamping units are arranged in parallel, and the adjacent ends of the second clamp 722 are constructed as clamping ends. The adjusting member 73 is used to adjust the distance between the corresponding clamping ends so that they can better fit the rough surface 51.

[0034] Specifically, such as Figure 5As shown, the adjusting member 73 includes a screw 731 arranged in the vertical direction, the bottom end of the screw 731 is rotatably connected to the clamping unit, and a nut 732 is provided on the clamp base 71 corresponding to the screw 731. The screw 731 passes through the nut 732 and cooperates with its thread. Rotating the screw 731 can drive the clamping unit to rise and fall.

[0035] Furthermore, the clamping ends of the first clamp 721 and the second clamp 722 are both provided with brushes, thereby achieving a better contact effect with the rough surface 51 .

[0036] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly, and they are not intended to limit the scope of protection of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims are included in the present invention.
