Description

TECHNICAL FIELD

[0001] The present application relates to the field of sewing technology equipment, in particular to a gantry rotary type super-thick material sewing machine. BACKGROUND

[0002] Sewing is a machine that uses one or more sewing threads to form one or more stitches on the sewing material, interweaving or sewing one or more layers of sewing material. The sewing of thin materials is relatively simple, and ordinary sewing machines can be used directly for sewing. However, the material needs to be compressed before sewing to avoid uneven thread, thread skipping, and poor sewing.

[0003] In order to effectively compress the material and effectively solve the problems of uneven thread and thread skipping, a design is made. For example, the patent with publication number CN212293987U discloses a full-automatic material straight-line sewing machine, which includes a feeding device, a limiting device, a sewing device, a discharging device, and a receiving frame. It can compress and transport the material, but it needs to use multiple cylinders to complete the material compression, movement, and sewing work. This not only leads to high cost and waste of electricity, but also causes environmental pollution and cannot guarantee the synchronization of the operation of the cooperating mechanisms, resulting in uneven thread and thread skipping during the transportation and sewing of the material.

[0004] Especially when the thickness of the material to be sewn is greater than 50mm, due to the increase in weight, the material is simply transported by friction, which can cause differences between the actual transportation speed of the material and the preset transportation speed during the sewing process, resulting in differences between the pattern embroidered on the surface of the material and the preset pattern.

[0005] Therefore, how to control the actual transportation speed of the material to be consistent with the preset transportation speed of the machine is one of the technical problems to be solved at present. SUMMARY

[0050] In order to further illustrate the technical means and effects taken by the present application to achieve the predetermined purposes, the specific embodiments, structures, features and effects according to the present application are described in detail as follows in combination with the drawings and preferred embodiments.

[0051] Embodiment 1

[0052] Referring to Figure 1 , the embodiment 1 discloses a gantry rotary type super-thick material sewing machine, which comprises a front end longitudinal moving mechanism 5, a sewing assembly 0 and a rear end longitudinal moving mechanism 6, the sewing assembly 0 is divided into a sewing machine head 3, a thread tensioning base 4 and a horizontal transverse moving mechanism 2; the front end longitudinal moving mechanism 5 and the horizontal transverse moving mechanism 2 are both provided with a clamping longitudinal moving device 1.

[0053] Referring to Figure 2 , the front end longitudinal moving mechanism 5 comprises a conveying belt 50, which can lift and transport the material, and is used to transport the material to the horizontal transverse moving mechanism 2.

[0054] Referring to Figure 11 , the sewing machine head 3 is located directly above the thread tensioning base 4, and the sewing machine head 3 cooperates with the thread tensioning base 4, and the sewing machine head 3 and the thread tensioning base 4 can rotate circumferentially on their vertical axes, and are used to sew a sewing line on the surface of the material.

[0055] Referring to Figure 11 , the horizontal transverse moving mechanism 2 connects the sewing head 3 and the thread tension base 4, and is used to control the horizontal transverse movement of the sewing head 3 and the thread tension base 4 on the material surface.

[0056] Referring to Figures 3 to 5 and Figure 10 , the clamping longitudinal moving device 1 comprises two side seats 10, a movable roller 11, a fixed roller 12, a plurality of outer support frames 14, a linkage shaft and a longitudinal moving driver 17.

[0057] The fixed roller 12 is fixedly pivoted at both ends thereof to the two side seats 10, and the fixed roller 12 passes through the side seats 10 at both ends thereof and is provided with a fixed wheel 120, and the fixed roller 12 and the fixed wheel 120 rotate synchronously. The side seat 10 is provided with a clamping driver 15 connected to the movable roller 11, and the clamping driver 15 is used to control the small amplitude up-down movement of the movable roller 11. The side seat 10 is provided with a movable slot 101 for the up-down adjustment of the movable roller 11, and the movable roller 11 passes through the movable slot 101. The movable roller 11 is provided with a movable wheel 110 at both ends thereof, and the movable roller 11 and the movable wheel 110 rotate synchronously. The outer support frame 14 is fixed to the side seat 10, and the outer support frame 14 is provided with an outer support wheel 140. All the outer support wheels 140, the fixed wheels 120 and the movable wheels 110 are synchronously driven by a same belt. The movable wheels 110 and the fixed wheels 120 rotate at the same speed, and the fixed roller 12 and the movable roller 11 rotate synchronously. The linkage shaft is provided with a linkage wheel 16 at both ends thereof, and the linkage wheel 16 is connected to the fixed wheels 120 of the two side seats 10 by a belt. The longitudinal moving driver 17 is connected to the linkage shaft.

[0058] The fixed wheel 120 is divided into a fixed inner wheel 1201 and a fixed outer wheel 1202. The fixed outer wheel 1202 is in the same plane as the outer support wheel 140 and the movable wheel 110. The fixed inner wheel 1201 is coaxial with the fixed outer wheel 1202 and rotates synchronously. The fixed inner wheel 1201 is connected to the linkage wheel 16.

[0059] The side seat 10 is further provided with an adjusting frame 13 provided with an adjusting slot 131 and an adjusting wheel 130. The adjusting frame 13 moves on the side seat 10 through the adjusting slot 131. The adjusting wheel 130 moves with the adjusting frame 13 and is used to adjust the relaxation of the belt to adjust the current height of the movable wheel 110.

[0060] When it is needed to clamp the material, the clamping driver 15 (a pneumatic cylinder is adopted in the present application) drives the movable roller 11 to press down by a small distance, so that the distance between the movable roller 11 and the fixed roller 12 is shortened, thereby achieving the purpose of clamping the material.

[0061] When the material is changed, the thickness changes, which will cause the belt between the wheels to be loose, so when the material is changed, the position of the adjusting frame 13 needs to be adjusted to adjust the tightness of the belt by the adjusting wheel 130.

[0062] The movable wheel 110 and the fixed wheel 120 are driven by the same belt, so the angular velocity of the movable wheel 110 and the fixed wheel 120 during rotation is the same, ensuring that the upper and lower surfaces of the cloth are fed in or out in the same direction and speed.

[0063] Meanwhile, referring to Figure 10 In this embodiment, the connecting shaft is connected to the longitudinal displacement driver 17, and the output of the longitudinal displacement driver 17 is transmitted to both ends of the connecting shaft, and finally the kinetic energy is transmitted to the movable wheel 110 and the fixed wheel 120 at both ends of the movable roller 11 and the fixed roller 12, so that the rotational speed applied to the movable roller 11 / fixed roller 12 is the same, and the forces at both ends of the two rollers are completely the same.

[0064] Referring to Figure 3 The front-end longitudinal displacement mechanism 5 includes a clamping longitudinal displacement device 1 for clamping the material and assisting the front-end longitudinal displacement mechanism 5 to transport the material towards the horizontal transverse displacement mechanism 2. The connecting wheel 16 in the clamping longitudinal displacement device 1 is connected to the conveying wheel 54 of the conveying belt 50, and the conveying belt 50 is wrapped around the outer diameter of the conveying roller 500, which has the same outer diameter as the fixed roller 12 and the movable roller 11.

[0065] Therefore, in the front-end longitudinal displacement mechanism 5, when the longitudinal displacement driver 17 is started, the fixed roller 12, the movable roller 11, and the conveying belt 50 can be rotated in the same direction and speed through the connecting structure, ensuring that the material moves at the same speed during the movement, avoiding material slipping.

[0066] Referring to Figures 7 to 10 The horizontal transverse displacement mechanism 2 includes two clamping longitudinal displacement devices 1, and the two clamping longitudinal displacement devices 1 share one longitudinal displacement driver 17. The clamping longitudinal displacement device 1 of the horizontal transverse displacement mechanism 2 is used to clamp the material and control the longitudinal movement of the material under the sewing head 3.

[0067] Therefore, in the horizontal transverse displacement mechanism 2, when the longitudinal displacement driver 17 is started, the two sets of fixed rollers 12 and movable rollers 11 (a total of 4 rollers with 8 end faces) can be rotated in the same direction and speed through the connecting structure, so as to clamp and longitudinally displace the material in a manner of biting the material.

[0068] Secondly, because the needle bar penetrates the material with large thickness during sewing, the needle bar will generate large kinetic energy during penetration, causing vibration. The clamping and longitudinal movement device 1 is used to fix the sewing area of the material to avoid material bouncing due to vibration and prevent the sewing lines from being skewed. Therefore, the clamping and longitudinal movement device 1 plays a certain auxiliary clamping role in the sewing area in addition to moving the material.

[0069] As shown in Figure 12 , the horizontal transverse movement mechanism 2 includes a transverse movement driver 20, a transverse movement linkage belt 21, a transverse movement linkage shaft 22, a head translation device 23, and a base translation device 24. The head translation device 23 includes a head wheel belt 230 and a head slide rail 231, and the head slide rail 231 is connected with the sewing head 3, which is fixed to the head wheel belt 230. The base translation device 24 includes a base wheel belt 240 and a base slide rail 241, and the base slide rail 241 is connected with the thread tensioning base 4, which is fixed to the base wheel belt 240. The head wheel belt 230 and the base wheel belt 240 are connected to the same transverse movement driver 20 through the transverse movement linkage belt 21 and the transverse movement linkage shaft 22. When the single transverse movement driver 20 moves, it can drive the sewing head 3 and the thread tensioning base 4 to move synchronously at the same speed and in the same direction.

[0070] The slide rails on the sewing head 3 and the thread tensioning base 4 can limit the moving direction and reduce friction.

[0071] The rear-end longitudinal movement mechanism 6 only has a conveying belt, which is mainly used to take out and send out the material after sewing from the sewing head 3. If the material area is relatively large, the rear-end longitudinal movement mechanism 6 also assists in lifting and moving the material to meet the sewing movement requirements.

[0072] Embodiment 2:

[0073] Referring to Figure 15 , on the front-end longitudinal movement mechanism 5, the surface of the conveying belt 50 is provided with a plurality of sliding grooves 501 and clamping pieces 51.

[0074] As shown in Figure 17 , the sliding grooves 501 are each provided with a guide column 502 and a spring 503, and the clamping pieces 51 are arranged on the upper guide columns 502 of the sliding grooves 501. In the absence of force on the clamping pieces 51, the springs 503 press the clamping pieces 51 towards the inner side of the conveying belt 50 for clamping the material.

[0075] As shown in Figure 16 , the front-end longitudinal movement mechanism 5 further includes two limiting flaps 53 and a clamping piece expander 52 for expanding the clamping pieces 51 to the position of the limiting flaps 53. The limiting flaps 53 can be adjusted in spacing to cooperate with materials of different widths to keep them moving in a straight line in one direction.

[0076] The clip expander 52 comprises an outer expansion inclined plate 520 and a limiting plate 521, the outer expansion inclined plate 520 is arranged obliquely, and the limiting plate 521 is located at the end position at the top of the outer expansion inclined plate 520.

[0077] Referring to Figure 17 When the clips 51 move from the lower part to the upper part along with the conveying belt 50 (i.e. when the conveying belt 50 is transferred from the lower part to the upper part via the conveying roller 500), the clips 51 pass through the outer expansion inclined plate 520, the outer expansion inclined plate 520 extrudes the clips 51 to move from the inner side to the outer side, so that the distance between the two clips 51 is equal to and corresponds to the distance between the two limiting plates 521 and the two limiting flaps 53. The horizontal length of the outer expansion inclined plate 520 is greater than the width of the chute 501.

[0078] Therefore, when the new clip 51 moves from the lower part to the upper part along with the conveying belt 50, the clip 51 is automatically opened when passing through the outer expansion inclined plate 520, so that the distance between the two clips 51 gradually expands to the limiting plate 521, when the clip 51 reaches the limiting plate 521, the opening size of the clip 51 is just corresponding to the material, after the clip 51 passes through the limiting plate 521, the clip 51 is automatically clamped on both sides of the material under the action of the spring 503.

[0079] Referring to Figure 20 The clip 51 further comprises a plurality of arc-shaped flip wheels 510, because the clip 51 rotates upward during the movement from the lower part to the upper part, the lateral extrusion force needs to be offset by the rotation of the flip wheels 510 during the upward movement of the clip 51. Because the clip 51 rotates, the flip wheels 510 need to be arranged in an arc shape to ensure that the flip wheels 510 are sequentially connected to form an arc-shaped contact rolling surface with the outer expansion inclined plate 520 during the rotation of the clip 51, and the flip wheels 510 are always in contact with the outer expansion inclined plate 520.

[0080] When the clip 51 moves upward to approach the maximum height (about to leave the outer expansion inclined plate 520), the moving speed of the clip 51 in the horizontal direction is obviously greater than the upward moving speed (the wear between the clip 51 and the outer expansion inclined plate 520 changes from the upward direction to the forward and backward direction), therefore, a plurality of transition wheel balls 511 are additionally arranged behind the flip wheels 510, the transition wheel balls 511 are in a plurality of rows of ball structures, the ball structure can minimize the wear between the clip 51 and the outer expansion inclined plate 520 when the clip 51 is about to leave the outer expansion inclined plate 520, and the transition wheel balls 511 are slightly inclined towards the outer expansion inclined plate 520 to ensure that the transition wheel balls 511 are always in contact with the outer expansion inclined plate 520 when the clip 51 leaves.
