Technical Field

[0001] The invention relates to the field of bath towel machines, in particular to a bath towel machine with parallel cutting. 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 parallel cutting bath towel machine 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 parallel cutting bath towel machine, comprising a base, on which a segmentation assembly is arranged, and the segmentation assembly is used to cut the bath towel, comprising a marking mechanism and a cutting assembly;

[0006] 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 satin surface has a top height and a friction coefficient lower than the fur surface; the calibration mechanism includes a limit part and a clamping part, and the limit part abuts against the satin surface and the edge line of the abutment away from the clamping part is arranged parallel to the boundary line;

[0007] The clamping portion clamps the hairy surface and moves in a direction away from the limiting portion, so that the satin surface slides relative to the limiting portion, and the hairy surface corresponding to the portion of the boundary line that abuts against the limiting portion stops moving.

[0008] Preferably, the limiting portion includes a pressing plate and a pressing plate driving device, and the pressing plate driving device drives the pressing plate to perform lifting movement, so that the pressing plate abuts against the satin surface and applies a first force to the satin surface;

[0009] The clamping part comprises a pair of clamps arranged corresponding to the upper and lower surfaces of the bath towel, the pair of clamps clamp the fleece surface and apply a second force, and the second force generates a friction force on the fleece surface that is greater than the first force on the satin surface.

[0010] Preferably, the clamping end of the clamp is provided with a brush, and the brush abuts against the hair surface.

[0011] Preferably, the clamp includes a crossbeam, and the clamping end of the clamp is composed of a plurality of clamping units independently arranged and perpendicular to the length direction of the bath towel, and any clamping unit is vertically connected to the crossbeam through an adjuster, and the adjuster is used to adjust the height of the corresponding clamping unit.

[0012] Preferably, the adjuster comprises a screw rod arranged in a vertical direction, the bottom end of the screw rod is rotatably connected to the clamping unit, a nut is arranged on the cross beam corresponding to the screw rod, and the screw rod passes through the nut and is threadably matched with the nut.

[0013] Preferably, the calibration mechanism comprises a calibration base fixed on the base, the calibration base is provided with a slide rail in the horizontal direction, the clamping part is connected to the calibration base via the slide rail, and drives the bath towel to move under the action of the calibration driving device.

[0014] Preferably, the cutting assembly comprises a cutting knife arranged on a side of the limiting portion away from the clamping portion, and the cutting knife is driven by a cutting knife driving device to perform a lifting movement to cut the bath towel.

[0015] Preferably, the cutting assembly further comprises a cutting knife guiding mechanism arranged on both sides of the cutting knife, the cutting knife guiding mechanism comprises sliding blocks fixed on both sides of any cutting knife, and the sliding blocks are cooperatedly arranged on a guide rail fixed on a calibration base along the cutting direction.

[0016] Preferably, it also includes a material roll and a material picking mechanism; the material roll is arranged on the side of the marking mechanism away from the cutting component, and the bath towel is wrapped and carried on the material roll; the material picking mechanism is arranged on the side of the cutting component away from the marking mechanism, and includes a material picking claw, which is extended by the material picking drive device, pulls one end of the bath towel and retracts, thereby taking the bath towel out of the material roll.

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] (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.

[0019] (2) In the present invention, the distance between the limiting portion and the cutting assembly in the horizontal direction is constant, so after the entire boundary line abuts against the limiting portion, the relative position of the satin surface on the cut bath towel has a high degree of consistency.

[0020] (3) The cutting assembly of the present invention is provided with a cutting blade guiding mechanism, which enables the cutting blade to stably perform cutting along a preset path without being easily deformed. In long-term use, a pair of cutting blades can ensure close meshing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The present invention is further described in detail below in conjunction with specific embodiments:

[0032] like Figure 1As shown, a parallel cutting bath towel machine comprises a base 1, on which a material roll 2, a segmentation assembly and a material taking mechanism 3 are arranged. A bath towel 6 is wound around the material roll 2, and the material taking mechanism 3 is arranged on a side of the segmentation assembly away from the material roll 2, and is used to take out the bath towel 6 from the material roll 2 and pass it through the segmentation assembly, and the segmentation assembly is used to cut the taken-out bath towel 6 into a preset length.

[0033] like Figure 7 As shown, the material taking mechanism 3 includes a material taking claw 31 , which is extended by the material taking driving device 32 , pulls one end of the bath towel 6 and retreats, thereby taking the bath towel 6 out of the material roll 2 .

[0034] like Figure 2 As shown, the surface of the bath towel 6 of this embodiment has a hairy surface 61 composed of fluff and a rectangular satin surface 62 made of silk. The hairy surface 61 and the satin surface 62 are alternately arranged in multiple groups when the bath towel 6 is not cut.

[0035] Because the bath towel 6 has a certain degree of elasticity, the length of the bath towel 6 taken by the material taking mechanism 3 each time is different, and the cut surface is difficult to be parallel to the satin surface 62.

[0036] In order to solve this problem, a calibration mechanism 4 is provided in the segment assembly.

[0037] like Figure 3 As shown, the marking mechanism 4 includes a limiting portion 41 and a clamping portion 42, wherein the clamping portion 42 is arranged close to the material roll 2, and the limiting portion 41 is arranged between the clamping portion 42 and the cutting assembly 5. Figure 4 As shown, the limiting part 41 includes a pressing plate 411, which is suspended above the satin surface 62 of the bath towel 6 and moves up and down under the drive of the pressing plate driving device 412, so that the pressing plate 411 abuts against the satin surface 62 of the bath towel 6. Figure 5 As shown, the clamping portion 42 includes a pair of clamps 421 arranged corresponding to the upper and lower surfaces of the bath towel 6 , and the pair of clamps 421 clamp the fleece surface 61 of the bath towel 6 and pull the bath towel 6 in a direction away from the limiting portion 41 .

[0038] The pressing plate driving device 412 drives the pressing plate 411 to apply a first force to the satin surface 62 of the bath towel 6, and the pair of clamps 421 apply a second force to the fur surface 61 of the bath towel 6. The satin surface 62 has a lower friction coefficient than the fur surface 61, and the second force of the clamps 421 on the fur surface 61 can generate a static friction force greater than the first force on the satin surface 62, so that the pressing plate 411 can slide along the satin surface 62.

[0039] The edge of the end of the pressing plate 411 away from the clamping portion 42 is straight, and during the sliding process, the edge will abut against the boundary line 63 between the fleece surface 61 and the satin surface 62. Therefore, when the position of the satin surface 62 is skewed and not perpendicular to the length direction of the bath towel 6, a part of the boundary line 63 will abut against the edge of the pressing plate 411, and the part on the boundary line 63 is set as the contact part; while the other part is not abutted and is at the end of the pressing plate 411 away from the clamping portion 42, and is set as the non-contact part.

[0040] Because the top height of the pile on the side of the pile surface 61 on the boundary line 63 is higher than that of the satin surface 62 (see the attached Figure 2 ), therefore, the contact portion will generate a traction force (maximum static friction force) on the bath towel 6 that is higher than the traction force of the clamping portion 42 on the furry surface 61, thereby causing the portion of the furry surface 61 clamped by the clamping portion 42 corresponding to the contact portion to slip and be unable to continue to drive the portion to move. As for the non-contact portion, since the pressing plate 411 is not in contact with it, the friction force of the pressing plate 411 on the satin surface 62 is less than the traction force of the clamping portion 42 on the furry surface 61, so the portion of the furry surface 61 corresponding to the non-contact portion can still be pulled and moved by the clamping portion 42, and finally the non-contact portion on the boundary line 63 also abuts against the edge line of the pressing plate 411, thereby causing the entire boundary line 63 to abut against the pressing plate 411 and present a straight state, completing the straightening of the bath towel 6. Because the horizontal distance between the limiting portion 41 and the cutting component 5 is fixed, the size of the bath towel 6 cut by the cutting component 5 is also equal at this time, that is, the calibration of the length of the bath towel 6 is completed.

[0041] The pulling action of the clamping portion 42 is achieved by the following structure: Figure 6 As shown, the calibration mechanism 4 also includes a calibration base 43 fixed on the base 1, and a slide rail 431 is arranged on the calibration base 43 in the horizontal direction. Both ends of the clamping part 42 are connected to the calibration base 43 through the slide rails 431, and a calibration drive device 432 is connected to the middle part. The end of the calibration drive device 432 away from the clamping part 42 is fixed to the calibration base 43, and is used to drive the clamping part 42 to move along the slide rail 431. The calibration drive device 432 can be a cylinder, a motor screw mechanism or other common drive devices.

[0042] In this embodiment, a brush is provided at the clamping end of the clamp 421, and the pair of clamps 421 abuts against the fleece surface 61 of the bath towel 6 through the brush and pulls the bath towel 6 to move.

[0043] like Figure 5 As shown, part or all of a pair of clamps 421 can be composed of independent clamping units 422. In this embodiment, the clamp 421 located at the upper end has a beam 424 arranged in the horizontal direction, and multiple clamping units 422 are arranged in parallel on the beam 424 through an adjuster 423, and any clamping unit 422 is arranged in the vertical direction.

[0044] The adjuster 423 is connected to the clamping unit 422 in a one-to-one correspondence, and is used to adjust the distance between the clamping unit 422 and the bath towel 6, thereby eliminating the problem of uneven traction on the hair surface 61 caused by the difference in brush length, and adjusting the magnitude of local traction. The adjuster 423 includes a screw rod arranged in the vertical direction, the bottom end of the screw rod is rotatably connected to the clamping unit 422, and a nut is arranged on the crossbeam 424 corresponding to the screw rod, and the screw rod passes through the nut and is threadedly matched with the nut. The height of the clamping unit 422 can be fine-tuned by rotating the screw rod.

[0045] like Figure 6 As shown, the cutting assembly 5 includes a cutting knife 51 disposed on the side of the limiting portion 41 away from the clamping portion 42. The cutting knife 51 is driven by the cutting knife driving device 52 to move up and down to cut the bath towel 6. The cut bath towel 6 is sent to the subsequent hemming equipment and unloading equipment.

[0046] In addition, if Figure 8 As shown, the cutting assembly 5 also includes a cutting blade guide mechanism 53 disposed on both sides of the cutting blade 51, and the cutting blade guide mechanism 53 includes a slider 531 fixed on both sides of any cutting blade 51, and the slider 531 is matched and disposed on a guide rail 532 fixed to the calibration base 43 along the cutting direction. Such a configuration enables the cutting blade 51 to stably move along the length direction of the guide rail 532, and is not prone to movement other than along the length direction of the guide rail 532, and is not prone to deformation, thereby ensuring that a pair of cutting blades 51 can be closely meshed during cutting, thereby ensuring the cutting quality.

[0047] When using:

[0048] The material taking claw 31 pulls the head end of the bath towel 6 in the material roll 2 under the drive of the material taking driving device 32, and runs through the segment assembly. At this time, the limiting part 41 of the marking mechanism 4 in the segment assembly is located above the satin surface 62 on the bath towel 6.

[0049] The pressing plate 411 in the limiting part 41 is driven by the pressing plate driving device 412 to descend and abut against the satin surface 62 on the bath towel 6. At the same time, the clamp 421 in the clamping part 42 clamps the fleece surface 61 of the bath towel 6. The clamp 421 is driven by the calibration driving device 432 to move along the slide rail 431 on the calibration base 43 in a direction away from the limiting part 41, overcoming the friction force of the pressing plate 411 on the satin surface 62, so that the boundary line 63 between the satin surface 62 and the fleece surface 61 on the bath towel 6 gradually moves toward the edge line of the pressing plate 411.

[0050] When the part of the non-straight boundary line 63 contacts one end of the pressing plate 411, the friction resistance at that place causes the clamp 421 at the corresponding position of the rough surface 61 to slip, so that the boundary line 63 contacting at that place is retained at the edge of the pressing plate 411 until the boundary line 63 and the pressing plate 411 are completely contacted, so that the pulled bath towel 6 is straightened, and the boundary line 63 and the cutting component 5 maintain a preset distance, and the length of the bath towel 6 is calibrated. The cutter 51 of the cutting component 5 is actuated to cut the bath towel 6.

[0051] 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 cannot be used 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 the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
