Description

Technical Field

[0001] The utility model relates to the technical field of towel processing equipment, in particular to a towel transverse sewing machine with a double blocking mechanism. Background Art

[0002] The working principle of the towel horizontal sewing machine is to first cut the towel strips with the two long sides sewn on the left and right sides one by one, then fold the two short sides, and finally sew the two short sides again.

[0003] A towel sewing machine can be divided into three parts based on their functions: the cutting section, the folding section, and the sewing section. The cutting section locates the cutting line on the towel fabric, aligns it, and cuts it. The folding section folds the cut short edges. The sewing section sews the two short edges.

[0004] After the towels are woven, dozens of towels are connected end to end to form a long strip. The towel cross-seam processing is to cut a towel completely from the long strip. The cutting position must be accurate and must be cut from the connection point of the two towels.

[0005] CN217127720U discloses a blocking mechanism for a towel horizontal sewing machine, belonging to the field of energy utilization equipment. It solves the problem of uneven towel edge cutting caused by uneven blocking in the prior art. In the technical solution of this application, the provision of a downward pressure spring ensures that each upper blocking block can be reliably reset. The provision of an airbag allows the upper blocking block to be fixed in position after pressing against the flat cloth portion of the towel, ensuring reliable blocking of the terry portion of the towel, making the towel cut more neatly, improving the cutting quality of the towel, and reducing the scrap rate. In addition, the coordination of the motor and the screw facilitates the adjustment of the drop distance of the upper blocking mechanism after changing batches of towels, thereby improving work efficiency.

[0006] However, a drawback of single-barrier cross-stitch machines is that the towel's length can stretch and deform due to tension fluctuations during the weaving process and the subsequent bleaching and dyeing process. This can lead to problems with towels cut with one barrier: while the back edge of the towel will be a standard length, the front edge will fluctuate. This doesn't affect the cut portion, but can cause the finished towel to have hair-pressing or hair-release defects on the front short edge, increasing the defect rate. Summary of the Invention

[0007] In view of the above-mentioned deficiencies in the prior art, a towel horizontal sewing machine with a double blocking mechanism is provided, which reduces the requirements for towel weaving and bleaching and dyeing, greatly improves the quality rate, and thus reduces production costs.

[0008] In order to solve the above technical problems, the technical solution adopted by the present invention is a towel sewing machine with a double blocking mechanism, including a towel sewing machine body, on which a first blocking device for blocking the rear end of the towel loop is provided, and a material pulling robot, and also includes a second blocking device for blocking the front end of the towel loop arranged corresponding to the first blocking device, and also includes a controller.

[0018] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1-3 As shown, a towel sewing machine with a double blocking mechanism includes a towel sewing machine body 1, a first blocking device for blocking the rear end of the towel loops, a material pulling robot, a second blocking device for blocking the front end of the towel loops, and a controller. The controller is a PLC.

[0020] The second blocking device includes a first blocking frame 2 provided on the towel horizontal sewing machine body 1, a first upper blocking mechanism that reciprocates along the height direction of the first blocking frame 2 is provided on the first blocking frame 2, and a first driving mechanism for driving the first upper blocking mechanism to reciprocate along the height direction of the first blocking frame, and a first lower blocking mechanism is provided below the first upper blocking mechanism; the first blocking device includes a second blocking frame 3 provided on the towel horizontal sewing machine body, a second upper blocking mechanism that reciprocates along the height direction of the second blocking frame 3 is provided on the second blocking frame 3, and a second driving mechanism for driving the second upper blocking mechanism to reciprocate along the height direction of the second blocking frame, and a second lower blocking mechanism is provided below the second upper blocking mechanism.

[0021] The first driving mechanism includes two first slide rails 5 correspondingly arranged on the first blocking frame 2 and arranged along the height direction of the first blocking frame, and a first slider 6 arranged on the first slide rail 5, a first driving block 7 is respectively provided on the two first sliders 6, a first horizontal plate 8 for connecting the two first driving blocks 7 is provided between the two first driving blocks 7, and a first vertical plate 9 is provided on the first horizontal plate 8. The first upper blocking mechanism is provided on the first vertical plate 9 and also includes a first driving device for driving the first driving block 7 to operate; the second driving mechanism includes two second slide rails correspondingly arranged on the second blocking frame 3 and arranged along the height direction of the second blocking frame 3, and a second slider arranged on the second slide rails, a second driving block is respectively provided on the two second sliders, a second horizontal plate for connecting the two second driving blocks is provided between the two second driving blocks, and a second vertical plate is provided on the second horizontal plate. The second upper blocking mechanism is provided on the second vertical plate and also includes a second driving device for driving the second driving block to operate.

[0022] The first driving device includes a first motor 4 and a first screw transmission group. The power input end of the first screw transmission group is connected to the power output end of the first motor, and the power output end of the first screw transmission group is connected to the first cross plate.

[0023] The second driving device includes a second motor and a second screw transmission group, the power input end of the second screw transmission group is connected to the power output end of the second motor, and the power output end of the second screw transmission group is connected to the second cross plate.

[0024] Of course, the first driving device and the second driving device are not limited to the driving structure of the motor and the screw rod, and can also be driven by a cylinder.

[0025] The first upper blocking mechanism, the second upper blocking mechanism, the first lower blocking mechanism, and the second lower blocking mechanism are the same as the upper blocking mechanism and the lower blocking mechanism disclosed in CN217127720U, and are not described in detail here.

[0026] The towel cross-stitching machine body is provided with a third slide rail 10 and a third slider 11 for carrying the first blocking frame 2, and a fourth slide rail and a fourth slider for carrying the second blocking frame. It also includes a third drive device for driving the first blocking frame 2 to run along the third slide rail 10, and a fourth drive device for driving the second blocking frame to run along the fourth slide rail. The third drive device and the fourth drive device can use existing drive structures such as oil cylinders and motor screw modules, which will not be described again. By providing the third slide rail 10 and the third slider 11, as well as the fourth slide rail and the fourth slider, the relative position of the first blocking frame 2 and the second blocking frame can be adjusted to meet different processing requirements.

[0027] On one side of the second blocking frame 3, there are movable upper and lower sweeping brushes. During the cutting operation, the towel is first pulled out by the pulling robot, and the towel flat cloth position between the two towels is pulled onto the second lower blocking mechanism. Then the second upper blocking mechanism falls and clamps the towel flat cloth with the second lower blocking mechanism. Finally, the upper and lower sweeping brushes sweep the material backwards, and the towel moves with the upper and lower sweeping brushes. When the towel moves, the intersection line between the loop and the flat cloth will move to the edge of the blocking position. Because the loop part is thicker than the flat cloth part, the loop part cannot pass through the slit between the second upper blocking mechanism and the second lower blocking mechanism, so that the cutting position of the towel is blocked, which is convenient for the next cutting. After the previous towel is cut and sent to the folding part, the pulling robot will come over to clamp the uneven side of the next towel and pull it out until it reaches the length of a towel. The degree of tension is adjusted so that the towel flat cloth behind the towel is completely located between the first upper blocking mechanism and the first lower blocking mechanism. After the material pulling robot is pulled out, the first upper blocking mechanism falls down and is stuck with the towel flat cloth corresponding to the first lower blocking mechanism. Then the clamping force of the material pulling robot is adjusted and the material pulling is continued. Since the towel loop is blocked and cannot enter, and the clamping force of the material pulling robot is small, when the first upper blocking mechanism and the first lower blocking mechanism block the junction of the loop and the flat cloth, the material pulling clip on the material pulling robot will slip and clamp the front of the towel in turn. The towel flat cloth is cut along the cut by the cutting mechanism on the towel horizontal sewing machine. The cutting mechanism on the towel horizontal sewing machine is prior art, and the material pulling robot is prior art, such as the grabbing robot and towel horizontal sewing machine disclosed in CN217757877U, which will not be described in detail here.

[0028] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
