Description

Technical Field

[0001] This utility model belongs to the field of sewing equipment technology, and relates to an adaptive pressing device for a template machine and a template machine. Background Technology

[0002] The template of the template machine needs to be pressed by a pressing device such as a pressure plate or a presser foot assembly. Regarding the working principle of the pressing device, you can refer to the patent document with application number 201810058772.9, which provides a presser foot assembly for a template machine. It includes: a power component for providing a vertically downward driving force; a template presser foot located below the power component for moving vertically under the driving force and capable of pressing the template; and a fabric presser foot located on the template presser foot for moving vertically under the driving force and capable of pressing the fabric.

[0003] In existing technology, when the template moves, there is moving friction between the presser foot and the template, resulting in relatively large frictional force. Summary of the Invention

[0004] This utility model addresses the aforementioned problems in the existing technology by providing an adaptive pressing device for a template machine. The technical problem to be solved by this utility model is: how to reduce friction.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] An adaptive pressing device for a template machine, the template machine including a housing, the adaptive pressing device including a mounting base and a driving component for moving the mounting base up and down, the driving component being mounted on the housing, characterized in that rolling elements are provided on one or both sides of the mounting base, and an elastic element is provided between the rolling elements and the mounting base.

[0007] Its working principle is as follows: When sewing is required, the mounting seat moves upward under the drive of the drive component. When the template moves to the sewing position on the worktable, the drive component drives the mounting seat to move downward, so that the bottom of the rolling element abuts and presses against the template. At this time, the elastic element is in a compressed state, and the rolling element presses the template. When sewing is finished, the mounting seat rises and leaves the template.

[0008] The rolling element of this adaptive clamping device has rolling friction between itself and the template. During the movement, the template experiences less friction and is less likely to be damaged.

[0009] In the above-mentioned adaptive pressing device for a template machine, the rolling element is a rolling bearing, and a guide shaft one that can move up and down is provided on the mounting base. The rolling bearing is located on one side of the guide shaft one, and the bottom of the rolling bearing is lower than the bottom of the guide shaft one; or / and a guide shaft two that can move up and down is provided on the mounting base. The rolling bearing is located on one side of the guide shaft two, and the bottom of the rolling bearing is lower than the bottom of the guide shaft two.

[0010] The elastic element is set on the top of guide shaft one and / or guide shaft two. The top of the elastic element is connected to the mounting base. The rolling bearing (rolling element) is set on the mounting base through guide shaft one, or through guide shaft two (in which case the rolling bearing is only set on one side of the mounting base), or the rolling bearing (rolling element) is set on the mounting base through guide shaft one and guide shaft two respectively (in which case the rolling bearing is set on both sides of the mounting base). The appropriate selection can be made according to different working conditions.

[0011] During operation, guide shaft one presses the template with rolling bearings, or guide shaft two presses the template with rolling bearings. During the movement, there is rolling friction between the rolling bearings and the template, and the template experiences less friction.

[0012] When guide shaft one and guide shaft two press the template together through rolling bearings, the elastic elements on guide shaft one and guide shaft two are in a compressed state. When the height of the template is inconsistent, the compression degree of the elastic elements on guide shaft one and guide shaft two is different, but the rolling bearings on guide shaft one and guide shaft two still press against the template to achieve adaptive adjustment.

[0013] In the aforementioned adaptive pressing device for a template machine, the rolling element is a universal bearing, and a guide shaft one that can move up and down is provided on the mounting base, with the universal bearing located at the bottom of the guide shaft one; or / and a guide shaft two that can move up and down is provided on the mounting base, with the universal bearing located at the bottom of the guide shaft two.

[0014] The elastic element is located on the top of guide shaft one and / or guide shaft two. The top of the elastic element is connected to the mounting base. The universal bearing (rolling element) is mounted on the mounting base via guide shaft one, or via guide shaft two (in which case the universal bearing is only mounted on one side of the mounting base), or the universal bearing (rolling element) is mounted on the mounting base via both guide shaft one and guide shaft two (in which case the universal bearing is mounted on both sides of the mounting base). The appropriate selection can be made according to different working conditions.

[0015] During operation, guide shaft one presses the template with a universal bearing, or guide shaft two presses the template with a universal bearing. During the movement, the universal bearing and the template are subjected to rolling friction, and the template is subjected to less friction.

[0016] In the above-mentioned adaptive pressing device for a template machine, the mounting base is provided with a vertically extending guide groove, the guide shaft is slidably connected in the guide groove, the elastic element is located in the guide groove, and the bottom and top of the elastic element are connected to the top of the guide shaft and the top wall of the guide groove.

[0017] The guide shaft is set in the guide groove. When the guide shaft comes into contact with the template, the guide shaft moves upward along the guide groove, and the elastic element is gradually compressed. During the compression of the elastic element, the guide shaft does not shake and is always in the vertical direction, ensuring that the guide shaft can stably press the template.

[0018] In the above-mentioned adaptive pressing device for a template machine, the mounting base is provided with a vertically extending guide groove II, the guide shaft II is slidably connected in the guide groove II, the elastic element is located in the guide groove II, and the bottom and top of the elastic element are connected to the top of the guide shaft II and the top wall of the guide groove II.

[0019] The second guide shaft is set in the second guide groove. When the first guide shaft abuts against the template, the second guide shaft moves upward along the guide groove, and the elastic element is gradually compressed. During the compression of the elastic element, the second guide shaft does not shake and is always in the vertical direction, ensuring that the second guide shaft can stably press the template.

[0020] In the adaptive pressing device of the template machine described above, a strip groove is provided on the groove wall of the first guide groove, the strip groove penetrates the groove wall of the first guide groove from the inside to the outside, and a guide pin is provided on the first guide shaft, the guide pin being slidably connected to the strip groove.

[0021] The guide pin is slidably connected in the slot, which plays a certain guiding role when the guide shaft moves. This structure can also prevent the guide shaft from rotating.

[0023] The guide pin is slidably connected in the slot, which plays a certain guiding role when the guide shaft moves. This structure can also prevent the guide shaft from rotating.

[0024] In the above-mentioned adaptive pressing device for a template machine, a presser foot rod that can move up and down is provided on the machine housing, and a middle presser foot is provided on the presser foot rod, which is located between guide shaft one and guide shaft two.

[0025] When the guide shaft 1 and guide shaft 2 press the template, the drive source drives the pressure foot rod to move downward, and the middle pressure foot can also press the template. The two guide shafts and the middle pressure foot work together to press the template, further improving the stability of the pressing.

[0026] In the aforementioned adaptive pressing device for a template machine, the driving component includes a cylinder, the mounting base is mounted on a large presser foot rod, the large presser foot rod is movably connected to the machine housing, and the large presser foot rod is connected to the output shaft of the cylinder.

Detailed Implementation

[0041] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0042] Example 1

[0043] like Figure 1-4 As shown, the template machine includes a housing 1, and the adaptive pressing device includes a mounting base 2 and a driving component 3 that drives the mounting base 2 to move up and down. The driving component 3 is mounted on the housing 1. Rolling elements 18 are provided on one or both sides of the mounting base 2, and elastic elements 6 are provided between the rolling elements 18 and the mounting base 2.

[0044] When sewing is required, the mounting base 2 moves upward under the drive of the drive component 3. When the template 15 moves to the sewing position on the worktable 16, the drive component 3 drives the mounting base 2 to move downward, so that the bottom of the rolling element 18 abuts and presses against the template 15. At this time, the elastic element 6 is in a compressed state, and the rolling element 18 presses against the template 15. When sewing is finished, the mounting base 2 rises away from the template 15. The elastic element 6 can be a spring or a rubber strip.

[0045] like Figure 6 As shown, in this embodiment, the rolling element 18 is a rolling bearing 11. A guide shaft 4 that can move up and down is provided on the mounting base 2.

A second guide shaft 5 that can move up and down is provided on the mounting base 2. The rolling bearing 11 is located on one side of the second guide shaft 5, and the bottom of the rolling bearing 11 is lower than the bottom of the second guide shaft 5. The structures of the first guide shaft 4 and the second guide shaft 5 can be identical.

[0046] In other embodiments, the rolling bearing 11 (rolling element) is mounted on the mounting base 2 via guide shaft 1 4, or via guide shaft 2 5 (in which case the rolling bearing 11 is only mounted on one side of the mounting base 2), or the rolling bearing 11 (rolling element) is mounted on the mounting base 2 via guide shaft 1 and guide shaft 2 respectively (in which case the rolling bearing 11 is mounted on both sides of the mounting base 2). The appropriate selection can be made according to different working conditions.

[0047] The elastic element 6 is set on the top of the guide shaft 4 and / or the second guide shaft 5. The top of the elastic element 6 is connected to the mounting base 2. During operation, the first guide shaft 4 presses the template 15 through the rolling bearing 11, or the second guide shaft 5 presses the template 15 through the rolling bearing 11. During the movement, there is rolling friction between the rolling bearing 11 and the template 15, and the template 15 experiences less friction.

[0048] When guide shaft 14 and guide shaft 25 press the template 15 together through rolling bearing 11, the elastic elements 6 on guide shaft 14 and guide shaft 25 are both in a compressed state. When the height of the template 15 is inconsistent, the compression degree of the elastic elements 6 on guide shaft 14 and guide shaft 25 is different, but the rolling bearing 11 on guide shaft 14 and guide shaft 25 still press against the template 15 to achieve adaptive adjustment.

[0052] The second guide shaft 5 is set in the second guide groove 8. When the first guide shaft 4 abuts against the template 15, the second guide shaft 5 moves upward along the guide groove, and the elastic element 6 is gradually compressed. During the compression of the elastic element 6, the second guide shaft 5 does not shake and is always located in the vertical direction, ensuring that the second guide shaft 5 can stably press the template 15.

[0053] like Figure 3 and 5 As shown, in this embodiment, a strip groove 9 is provided on the groove wall of the guide groove 7. The strip groove 9 penetrates the groove wall of the guide groove 7 from the inside to the outside. A guide pin 10 is provided on the guide shaft 4. The guide pin 10 is slidably connected to the strip groove 9.

[0057] like Figure 2 and 3 As shown, in this embodiment, a presser foot rod 13 that can move up and down is provided on the housing 1, and a middle presser foot 14 is provided on the presser foot rod 13. The middle presser foot 14 is located between the guide shaft 4 and the guide shaft 5.

[0058] When the guide shaft 4 and guide shaft 5 press the template 15, the drive source drives the presser foot rod 13 to move downward, and the middle presser foot 14 can also press the template 15. The two guide shafts and the middle presser foot 14 work together to press the template 15, further improving the stability of the pressing.
