Description

Technical Field

[0001] The invention relates to the field of bath towel manufacturing, and in particular to a bath towel forming machine and a forming method thereof. Background Art

[0002] Bath towels are a type of towel. Made of pure cotton yarn, they are divided into yarn-woven bath towels and thread-woven bath towels. The height and density of the terry loops are higher and denser than those of face towels and pillow towels, and their water absorption, water storage and warmth retention are better than other towels. They are mainly used to wipe and cover the body after bathing, and are also often used to cover the body to prevent coldness.

[0003] Some hotels use bath towels with satin decorations made of satin materials. During the manufacturing process of such bath towels, it is necessary to keep the relative position of the satin decoration of each cut bath towel consistent to avoid different decoration positions of bath towels in the same batch. However, because bath towels are elastic, they are prone to deformation during material collection and cutting, causing the decoration to be skewed, affecting the quality of the finished product. Traditional bath towel manufacturing equipment is difficult to overcome this difficulty. Summary of the invention

[0004] The purpose of the present invention is to provide a bath towel forming machine and a forming method thereof, so as to solve the problem that the decorative part is easily skewed during the bath towel cutting process in the prior art.

[0005] The technical solution of the present invention is: a bath towel forming machine, comprising a base, on which a feeding assembly, a parallel cutting assembly, a transfer mechanism and an edge binding assembly are arranged;

[0006] The feeding assembly includes a material roll carrying a bath towel and a material taking mechanism disposed at one end of the parallel cutting assembly away from the material roll, and the material taking mechanism pulls the bath towel through the parallel cutting assembly;

[0007] The bath towel has a fur surface and a satin surface, and the fur surface and the satin surface form a boundary line perpendicular to the length direction of the bath towel; the parallel positioning device has a limiting portion whose end surface is parallel to the cutting mechanism, and the limiting portion can abut against the boundary line, so that the boundary line is parallel to the cutting end of the cutting mechanism;

[0008] The edge binding assembly comprises a positioning mechanism and a first folding plate and a second folding plate which move successively. The first folding plate and the second folding plate cooperate with the positioning mechanism to perform two edge binding on the edge of the bath towel.

[0009] Preferably, a clamping portion is provided on the side of the limiting portion away from the material taking mechanism, wherein the clamping portion has a clamping end capable of clamping the fleece surface of the bath towel, and driven by the parallel driving device, pulls the bath towel toward the side away from the limiting portion.

[0010] Preferably, the limiting portion comprises a limiting pressure plate, which is arranged corresponding to the satin surface of the bath towel and has a straight edge on the side away from the clamping portion; the bath towel slides on the abutting end of the limiting pressure plate driven by the clamping portion.

[0011] Preferably, the traction force of the clamping part on the fleece surface is set to F1; the resistance of the limit pressure plate on the satin surface and the boundary line of the bath towel is set to F2 and F3 respectively; and F3>F1>F2 is satisfied.

[0012] Preferably, the first folding plate and the second folding plate respectively fold the first part and the second part of the bath towel in succession under the drive of the folding driver; the positioning mechanism includes a positioning pressure plate, and the positioning pressure plate cooperates with the first folding plate and the second folding plate to successively abut against the inner side of the first part and the inner side of the second part of the bath towel under the drive of the positioning drive device.

[0013] Preferably, a accommodating mechanism is also provided, which includes a accommodating groove opened on the base, the head end of the accommodating groove is arranged corresponding to the material taking mechanism, and is cooperated with a accommodating driver, which abuts against the bath towel through lifting movement and pushes the middle part of the bath towel into the accommodating groove for storage.

[0014] Preferably, the transfer mechanism includes a transfer base fixed on a base, and the transfer base is connected to a transfer pressure plate via a transfer driver, and the transfer driver drives the transfer pressure plate to abut against the bath towel, and drives the transfer pressure plate to move the bath towel along the length direction of the accommodating groove.

[0015] A bath towel forming method comprises the following steps:

[0016] Step 1: The bath towel in the material roll of the material taking mechanism is clamped and carried through the parallel cutting assembly during the resetting process;

[0017] Step 2: The limiting part abuts against the satin surface of the bath towel, and the clamping part clamps the fleece surface of the bath towel and pulls the bath towel to move in a direction away from the limiting part; the boundary line gradually abuts against one side of the limiting pressure plate, so that the satin surface tends to be straight; the cutting mechanism abuts against the bath towel into a preset size;

[0018] Step three, the transfer mechanism carries the cut bath towel along the accommodating groove into the edge binding assembly, and the positioning mechanism in the edge binding assembly cooperates with the first folding plate and the second folding plate that move successively to fold the first part and the second part of the edge of the bath towel twice, and sews the folded part in the subsequent sewing station to complete the edge binding.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] (1) The present invention is provided with a limiting portion, which abuts against the satin surface of the bath towel and relies on the difference in friction force at the boundary line between the satin surface and the fur surface. When the clamping portion pulls the fur surface of the bath towel to move, the portion where the boundary line abuts against the limiting portion generates huge resistance, causing the fur surface corresponding to the abutting portion and the clamping portion to slip and stop moving, while the portion not abutting continues to move, thereby ensuring the straightness of the satin surface during cutting.

[0021] (2) An edge binding assembly is provided, and a first folding plate and a second folding plate that move successively are used to fold the first and second parts of the edge of the bath towel twice through a positioning mechanism in the edge binding assembly, and the folded parts are sewn in a subsequent sewing station to complete the edge binding.

[0022] (3) A storage structure is also provided so that the middle part of a longer fabric such as a bath towel that does not need to be processed can be folded and stored, thereby reducing the space occupied by the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The present invention is further described in detail below in conjunction with specific embodiments:

[0036] like Figure 1 and Figure 2 As shown, a bath towel forming machine comprises a base 1 on which a feeding assembly 2, a parallel cutting assembly 3, a transfer mechanism 4 and an edge wrapping assembly 5 are arranged.

[0037] Among them, combined Figure 3 As shown, the feeding assembly 2 includes a material roll 21 and a material taking mechanism 22, and the uncut bath towel raw material is wound around the material roll 21. The material taking mechanism 22 is arranged on the side of the parallel cutting assembly 3 away from the material roll 21, and includes a material taking claw 221 and a material taking drive 222. The material taking drive 222 drives the material taking claw 221 to move toward the material roll 21, clamps the bath towel 6 in the material roll 21, and pulls out the bath towel 6 during the resetting process. In addition, the material taking claw 221 itself can swing around the hinged end with the material taking drive 222, so as to control the release of the bath towel 6.

[0038] The material-taking claw 221 grabs one end of the bath towel material in the material roll 21, and allows the bath towel material to pass through the parallel cutting assembly 3, so that the part of the bath towel material to be cut falls into the cutting station, and the cutting mechanism 32 in the parallel cutting assembly 3 is used to cut the part of the bath towel material into a bath towel 6 of a preset size. In this embodiment, the cutting mechanism 32 has a pair of cutting knives.

[0039] like Figure 4As shown, the bath towel 6 in this embodiment is composed of two parts, including a fur surface 61 that occupies most of the area and a satin surface 62 that serves as a decoration and is perpendicular to the length direction of the bath towel 6. The fur surface 61 has fluff, and the satin surface 62 is made of a smooth satin material, and two straight boundary lines 63 are formed between the fur surface 61 and the satin surface 62.

[0040] Because the bath towel 6 is made of soft and easily deformable cloth, it is easy for the bath towel 6 to be deformed during the pulling process of the material taking mechanism 22, which causes the satin surface 62 of the bath towel 6 to be non-parallel with the cut end after cutting, which does not meet the requirements. In addition, the position of the end of the bath towel 6 grabbed by the material taking mechanism 22 each time is not very accurate, which also easily causes the length of each bath towel 6 to be inconsistent after cutting.

[0041] To this end, the parallel cutting assembly 3 is also provided with a parallel positioning device 31, such as Figure 5 and Figure 6 As shown, the parallel positioning device 31 includes a limiting portion 311 parallel to the cutting mechanism 32 , and a clamping portion 312 is further provided at one end of the limiting portion 311 away from the cutting mechanism 32 .

[0042] Specifically, the limiting part 311 includes a limiting base 3111, on which a limiting pressing plate 3112 is slidably arranged, and the limiting pressing plate 3112 is driven by a limiting driver 3113 to perform a lifting motion. The bottom end of the limiting pressing plate 3112 can abut against the satin surface 62 of the bath towel 6, and exert a resistance F2 on the satin surface 62 of the bath towel 6 in the horizontal direction. The clamping portion 312 includes a clamping base 3121, on which a pair of clamps 3122 for clamping in a vertical direction are arranged. The material picking mechanism 22 pulls the bath towel 6 through a pair of clamping ends of the clamp 3122. The clamp 3122 clamps the furry surface 61 of the bath towel 6 and applies a traction force of magnitude F1 to the furry surface 61, and driven by the fixed-length driver 3123, the bath towel 6 is pulled to move along the slide rails 3124 arranged on both sides of the clamping base 3121 in a direction away from the limiting portion 311.

[0043] F1 is controlled to be greater than F2, so that the satin surface 62 of the bath towel 6 slides relative to the limiting plate 3112 under the traction of the clamping part 312. Because the raw edge of the bath towel 6 is composed of fluff, the side of the fluff surface 61 is higher than the side of the satin surface 62 at the junction 63. When the junction 63 moves toward the limiting plate 3112 as a whole with the traction of the clamping part 312, the skewed part closer to the limiting plate 3112 will first abut against the limiting plate 3112, so that the limiting plate 3112 generates a resistance force of F3 on the junction 63, and F3 is greater than the traction force F2 of the clamping part 312 on the fluff surface 61, thereby causing the fluff surface 61 corresponding to the junction 63 abutting against the limiting plate 3112 and the clamping end of the clamping part 312 to slip, so that the limiting plate 3112 and the junction 63 remain relatively still.

[0044] Similarly, the portion of the boundary line 63 that is not in contact with the limiting plate 3112 will continue to be driven by the clamping portion 312 to move toward the limiting plate 3112, and finally contact with the limiting plate 3112. The contact portion between the limiting plate 3112 and the boundary line 63 is set to be straight and perpendicular to the length direction of the bath towel 6, so that the satin surface 62 of the bath towel 6 on the cutting station can be straight, thereby solving the problem that the satin surface 62 of the bath towel 6 is easily skewed during cutting.

[0045] Furthermore, the horizontal distance between the cutting mechanism 32 and the limiting portion 311 is kept fixed during the operation. Therefore, the limiting pressing plate 3112 integrally abutting against the boundary line 63 can be used as a reference for cutting the bath towel 6, so that the size of the bath towel 6 is the same after each cutting.

[0046] Because the bath towel 6 has a relatively long length, a receiving mechanism 7 is also provided in this embodiment. Figure 2 and Figure 7 As shown, the accommodating mechanism 7 includes an accommodating groove 71 opened on the base 1, one end of the accommodating groove 71 is arranged between the material taking mechanism 22 and the limiting part 311 perpendicular to the length direction of the bath towel 6, and the other end extends to the unloading mechanism through the edge binding component 5. An accommodating driver 72 is arranged above the accommodating groove 71, and the accommodating driver 72 includes an accommodating base mounted on the base 1, and a push rod 73 is arranged on the accommodating base. The push rod 73 abuts against the bath towel 6 through a lifting action and descends into the accommodating groove 71, and the middle part of the bath towel 6 that does not need to be processed is pushed into the accommodating groove 71 for folding, and only the edge of the bath towel 6 that needs to be edged is carried on the base 1, thereby reducing the size of the base 1.

[0047] In order to achieve a better hemming effect, the edge of the bath towel 6 in the present application needs to be hemmed twice, that is, the first part 64 and the second part 65 of the edge of the bath towel 6 are folded successively.

[0048] The edge wrapping component 5 includes: Figure 8and Fig. 9 The positioning mechanism 51, the first folding plate 52 and the second folding plate 53 are shown. The positioning mechanism 51 is suspended above the base 1 and has a positioning plate 511. The positioning plate 511 is lifted and lowered and moved horizontally under the drive of the positioning driver 512. The first folding plate 52 and the second folding plate 53 are respectively arranged corresponding to the first part 64 and the second part 65 of the bath towel 6, and are respectively connected to the corresponding folding driver 54. The folding driver 54 includes a plurality of cylinders in the horizontal direction and the vertical direction.

[0049] The transfer mechanism 4 includes a transfer base 41 fixed on the base 1, and a transfer pressure plate 43 is connected to the transfer base 41 through a transfer driver 42. The transfer driver 42 drives the transfer pressure plate 43 to abut against the bath towel 6, and drives the transfer pressure plate 43 to drive the bath towel 6 to move along the length direction of the accommodating groove 71.

[0050] refer to Fig.10 , the transfer mechanism 4 moves the bath towel 6 along the receiving groove 71 to the hemming assembly 5, and the positioning plate 511 moves to the inner side of the first part 64 of the bath towel 6, so that one side of the positioning plate 511 serves as the positioning edge when folding. The first folding plate 52 is first lifted up under the drive of the folding driver 54, and then moves toward the inner side of the bath towel 6 in the horizontal direction, so as to fold the first part 64 of the bath towel 6. Subsequently, the positioning plate 511 moves toward the inner side of the bath towel 6 and is pulled out from the folded first part 64. Through the sequential lifting and lowering movements, the first folding plate 52 is replaced to press the folded first part 64 to prevent the folded first part 64 from spreading. At this time, the positioning plate is located at the inner side of the second part 65, which is used for positioning the second folding. The second folding plate 53 repeats the action of the first folding plate 52 under the drive of the folding driver 54 to complete the folding of the second part 65 of the bath towel 6.

[0051] Subsequently, the positioning pressing plate 511 is pulled out from the folded second part 65, and the transfer pressing plate 43 descends to replace the second folding plate 53 to press the edge, and carries the bath towel 6 along the accommodating groove 71 into the subsequent sewing station to sew the edge.

[0052] Furthermore, in the present embodiment, the hemming components 5 are symmetrically arranged as a pair relative to the receiving groove 71 , and can hem both sides of the bath towel 6 at the same time.

[0053] When using:

[0054] One end of the bath towel material in the roll 21 is manually pulled onto the base 1, and the material taking claw 221 extends to engage with the portion and carries the bath towel 6 through the parallel cutting assembly 3 during the resetting process. Subsequently, the accommodating driver 72 drives the push rod 73 to move, pushing the middle part of the bath towel 6 into the accommodating groove 71.

[0055] The limiting part 311 abuts against the satin surface 62 of the bath towel 6, and the clamping part 312 clamps the fleece surface 61 of the bath towel 6 and pulls the bath towel 6 to move in a direction away from the limiting part 311. As the boundary line 63 of the bath towel 6 gradually abuts against one side of the limiting pressure plate 3112, the satin surface 62 tends to be straight.

[0056] The cutting mechanism 32 is activated to cut the bath towel material into bath towels 6 of a preset size. Then, the transfer mechanism 4 carries the cut bath towel 6 along the receiving groove 71 into the edge binding assembly 5. The positioning mechanism 51 in the edge binding assembly 5 cooperates with the first folding plate 52 and the second folding plate 53 that move successively to fold the first part 64 and the second part 65 of the edge of the bath towel 6 twice, and sews the folded part in the subsequent sewing station to complete the edge binding.

[0057] Then it continues to move along the accommodating groove 71 to the unloading mechanism to complete unloading.
