Description

Technical Field

[0001] The utility model relates to a glue - applying head, and particularly to an adjustable glue - applying head. Background Art

[0002] In the manufacturing process of seamless underwear and panties, a glue - applying head is usually used to perform continuous glue - applying operations along the corresponding positions of the edges of two pieces of fabric, and then the two pieces of fabric are bonded together. At present, existing glue - applying equipment generally combines three driving methods: horizontal, vertical, and rotational to drive the glue - applying head. Since the glue - applying head needs to be connected to a glue inlet pipe, the rotational amplitude of the glue - applying head is limited and it cannot perform 360° rotational glue - applying. Moreover, in the actual production process, the same underwear or panties have various different glue - applying requirements, and different glue - applying heads need to be replaced, and the installation and disassembly are very cumbersome.

[0003] In view of the above - mentioned technical problems, the inventor of the present application previously applied for a detachable rotary glue - applying mechanism (Patent No.: ZL202321017920.5), which enables 360° rotational glue - applying and can randomly and quickly replace the glue - applying head according to production requirements, and the installation and disassembly are very convenient. However, in subsequent use, it is found that the glue - applying head of the previously applied glue - applying mechanism cannot be adjusted in the inclination degree in the left - right direction and cannot adapt to the glue - applying requirements of some inclined surfaces. Therefore, the original glue - applying head needs to be improved. Summary of the Invention

[0004] The problem to be solved by the utility model is to provide an adjustable glue - applying head that can be adjusted in the inclination degree in the left - right direction to adapt to the glue - applying requirements of inclined surfaces. The adopted technical solution is as follows:

[0005] An adjustable glue - applying head includes a glue - applying base, a glue - applying head fixing mechanism, and a glue - applying head body. The glue - applying head body is installed on the lower surface of the glue - applying base through the glue - applying head fixing mechanism. The glue - applying head body includes a first pressing block and a second pressing block that are pressed and locked together. The first pressing block is provided with a first pressing surface, and the second pressing block is provided with a second pressing surface. The first pressing surface and the second pressing surface are relatively matched. A glue channel is provided in the first pressing block. The inlet of the glue channel is arranged on the upper surface of the first pressing block, and the outlet of the glue channel is arranged in the middle of the surface of the first pressing surface. The lower edge of the first pressing surface or the second pressing surface serves as the glue outlet of the glue - applying head body. It is characterized in that: the adjustable glue - applying head further includes a glue - outlet adjusting mechanism for adjusting the left - right inclination of the glue - applying head body, and the glue - outlet adjusting mechanism is arranged at the glue - applying head fixing mechanism.

[0006] The above - mentioned glue - applying base is installed on the lower surface of the rotating seat of the entire glue - applying mechanism. For the specific structure of the glue - applying mechanism, reference can be made to the Chinese patent "A detachable rotary glue - applying mechanism" (Patent No.: ZL202321017920.5) previously applied by the inventor, which will not be elaborated here.

[0007] The above-mentioned glue discharging adjusting mechanism is arranged on the glue applying head fixing mechanism. By adjusting the positional relationship between the glue applying head body and the glue applying head fixing mechanism, the left-right inclination of the glue applying head body is further adjusted, so that the glue applying head can adapt to the glue applying requirements of the inclined surface.

[0008] Between the above-mentioned first pressing block and the second pressing block, screw holes can be opened and locked with screws.

[0009] As a preferred solution of the present utility model, the glue applying head fixing mechanism includes two limiting blocks, as well as a first clamping member and a second clamping member; the two limiting blocks are oppositely arranged on both side edges of the lower surface of the glue applying base, the first clamping member and the second clamping member are respectively locked on the opposite sides of the two limiting blocks, and the linear direction where the two limiting blocks are located is perpendicular to the linear direction where the first clamping member and the second clamping member are located; the upper part of the glue applying head body is clamped between the first clamping member, the second clamping member and the two limiting blocks.

[0010] As a further preferred solution of the present utility model, the first clamping member is locked on the lower surface of the glue applying base in the vertical direction; the two sides of the second clamping member are respectively locked on the two limiting blocks in the horizontal direction. The first clamping member and the second clamping member cooperate respectively in the vertical direction and the horizontal direction to clamp the glue applying head body below the glue applying base. Between the glue applying base and the first clamping member, and between the limiting block and the second clamping member, an insertion and locking cooperation mode can be adopted, or a mode of opening screw holes at corresponding positions and locking with screws can be adopted.

[0011] As a further preferred solution of the present utility model, the first clamping member is provided with a first inclined surface on the side facing the second clamping member, and the upper part of the glue applying head body is provided with a second inclined surface on the side in contact and cooperation with the first clamping member, and the first inclined surface is in contact and cooperation with the second inclined surface; the limiting block is provided with a horizontally oriented guiding screw hole and a guiding slot, the second clamping member is provided with guiding through holes matching the guiding screw holes at positions corresponding to the two limiting blocks, the two end parts of the second clamping member are in corresponding clamping and cooperation with the guiding slot, and both the guiding through holes and the guiding screw holes are locked by adjusting screws; the first clamping member, the second clamping member, and the two adjusting screws together constitute the glue discharging adjusting mechanism.

[0012] When the second clamping member is locked on the two limiting blocks, it squeezes the upper part of the glue applying head body towards the direction where the first clamping member is located, so that the first inclined surface is in contact and cooperation with the second inclined surface, and the mutual contact area between the first inclined surface and the second inclined surface is affected by the locking degree of the adjusting screw; when the locking degrees of the two adjusting screws are different, the contact area of the corresponding contact region between the first inclined surface and the second inclined surface is different, making the glue applying head body tilt towards the looser side, thereby adjusting the inclination of the glue applying head body in the left-right direction.

[0013] As a preferred embodiment of the present utility model, a groove is provided along the circumferential direction of the inlet of the glue channel, and an elastic sealing ring is sleeved in the groove. The thickness of the elastic sealing ring is greater than the depth of the groove, and the upper surface of the elastic sealing ring is in close contact with the lower surface of the glue application base. In order to prevent glue leakage when the inclination of the glue application head body is adjusted, an elastic sealing ring is provided around the inlet of the glue channel to ensure that the elastic sealing ring is always in close contact with the lower surface of the glue application base regardless of how the inclination of the glue application head body is adjusted.

[0014] On the other hand, in actual use, it is also found that the glue output of the glue application head is prone to unevenness, which affects the glue application quality. Therefore, as a preferred embodiment of the present utility model, a plurality of equally wide glue output channels are provided along the length direction of the lower edge of the first pressing surface or the second pressing surface, and the lengths of the glue output channels decrease from the middle to both sides.

[0015] The above-mentioned glue output channels are used for the outflow of glue. The glue flows out from the glue channel inside the first pressing block and spreads to fill the space between the first pressing surface and the second pressing surface, and then flows out through each glue output channel. Since the outlet of the glue channel in the first pressing block is arranged in the middle of the surface of the first pressing surface, the spreading speed and spreading flow rate of the glue on the surface of the first pressing surface are not equal. The amount of glue near the outlet of the glue channel in the middle is more, and the amount of glue near both sides of the first pressing surface is less. Therefore, by setting the glue output channels at the lower edge of the first pressing surface or the second pressing surface to be equally wide and their lengths to decrease from the middle to both sides, on the one hand, the upper ports of each glue output channel form a guiding surface inclined from the middle to both sides, enabling the glue in the middle to spread to both sides more quickly; on the other hand, by restricting the width of the glue output channels to be equal, the amount of glue flowing out of each glue output channel is equal, so that the overall glue output of the glue application head is uniform, ensuring the glue application quality.

[0016] Compared with the prior art, the present utility model has the following advantages:

[0017] The present utility model can adjust the glue application head to be provided with a glue output adjustment mechanism at the glue application head fixing mechanism. By adjusting the positional relationship between the glue application head body and the glue application head fixing mechanism, the left-right inclination of the glue application head body can be adjusted, so that the glue application head can adapt to the glue application requirements of the inclined surface; moreover, the glue output channels at the lower edge of the first pressing surface or the second pressing surface are set to be equally wide and their lengths are set to decrease from the middle to both sides, making the overall glue output of the glue application head uniform and ensuring the glue application quality.

Specific embodiments

[0024] The following further describes in conjunction with the accompanying drawings and the preferred embodiments of the present invention.

[0025] As Figures 1 to 3 shown, an adjustable glue application head includes a glue application base 1, a glue application head fixing mechanism 2, a glue application head body 3, and a glue outlet adjusting mechanism; the glue application head body 3 is installed on the lower surface of the glue application base 1 through the glue application head fixing mechanism 2, and the glue application head fixing mechanism 2 includes two limit blocks 21, as well as a first clamping member 22 and a second clamping member 23; the two limit blocks 21 are relatively arranged on both side edges of the lower surface of the glue application base 1, and the first clamping member 22 is locked along the vertical direction on the lower surface of the glue application base 1; the limit block 21 is provided with a horizontal guiding screw hole 211 and a guiding card slot 212, and the second clamping member 23 is correspondingly provided with a guiding through hole 231 matching the guiding screw hole 211 at the corresponding positions of the two limit blocks 21. The two ends of the second clamping member 23 are correspondingly clamped and matched with the guiding card slot 212. The guiding through hole 231 and the guiding screw hole 211 are both locked through the adjusting screw 232, so that both sides of the second clamping member 23 are respectively locked on the two limit blocks 21 along the horizontal direction, and the straight line direction where the two limit blocks 21 are located is perpendicular to the straight line direction where the first clamping member 22 and the second clamping member 23 are located; the first clamping member 22 is provided with a first inclined surface 221 on the side facing the second clamping member 23, and the upper part of the glue application head body 3 is provided with a second inclined surface 33 on the side in contact and cooperation with the first clamping member 22. The first inclined surface 221 is in contact and cooperation with the second inclined surface 33. The first clamping member 22, the second clamping member 23, and the two adjusting screws 232 together constitute the glue outlet adjusting mechanism.

[0026] The first clamping member 22 and the second clamping member 23 are respectively locked on the opposite sides of the two limiting blocks 21. The upper part of the glue - applying head body 3 is clamped between the first clamping member 22, the second clamping member 23 and the two limiting blocks 21, and is cooperated from the vertical direction and the horizontal direction respectively to clamp the glue - applying head body 3 under the glue - applying base 1. When the second clamping member 23 is locked to the two limiting blocks 21, it squeezes the upper part of the glue - applying head body 3 towards the direction where the first clamping member 22 is located, so that the first inclined surface 221 contacts and cooperates with the second inclined surface 33. The mutual contact area between the first inclined surface 221 and the second inclined surface 33 is affected by the tightening degree of the adjusting screw 232. When the tightening degrees of the two adjusting screws 232 are different, the contact area between the corresponding first inclined surface 221 and the second inclined surface 33 is different, causing the glue - applying head body 3 to tilt towards the looser side, thereby adjusting the inclination of the glue - applying head body 3 in the left - right direction so that the glue - applying head can meet the glue - applying requirements of the inclined surface.

[0027] As Figures 1 to 5 shown, the glue - applying head body 3 includes a first pressing block 31 and a second pressing block 32 which are pressed and locked together. The first pressing block 31 is provided with a first pressing surface 311, and the second pressing block 32 is provided with a second pressing surface (not marked in the figure as it is blocked). The first pressing surface 311 and the second pressing surface are relatively cooperated. A glue channel is provided in the first pressing block 31. The inlet 312 of the glue channel is arranged on the upper surface of the first pressing block 31, and the outlet 313 of the glue channel is arranged in the middle of the surface of the first pressing surface 311. A groove 314 is arranged along the circumferential direction of the inlet 312 of the glue channel, and an elastic sealing ring 4 is sleeved in the groove 314. The thickness of the elastic sealing ring 4 is greater than the depth of the groove 314. The upper surface of the elastic sealing ring 4 is in close contact with the lower surface of the glue - applying base 1. In this embodiment, the elastic sealing ring can be made of elastic materials such as silica gel and rubber. A plurality of equal - width glue - discharging channels 5 are arranged along the length direction of the lower edge of the first pressing surface 311. The lengths of the glue - discharging channels 5 decrease from the middle to both sides, and the lower edges of the glue - discharging channels 5 are used as the glue - discharging ports of the glue - applying head body 3.

[0028] In order to prevent glue leakage when the glue application head body 3 is adjusted in inclination, an elastic sealing ring 4 is provided around the entrance 312 of the glue channel to ensure that no matter how the inclination of the glue application head body 3 is adjusted, the elastic sealing ring 4 is always in close contact with the lower surface of the glue application base 1. On the other hand, it is also found in actual use that the glue output of the glue application head is prone to be uneven, which affects the glue application quality. Therefore, the glue output channels 5 at the lower edges of the first pressing surface 311 or the second pressing surface are set to have the same width and their lengths are set to decrease from the middle to both sides. The glue flows out from the glue channel inside the first pressing block 31 and spreads to fill the space between the first pressing surface 311 and the second pressing surface, and then flows out through each glue output channel 5. On the one hand, the upper ports of each glue output channel 5 form a guiding surface inclined from the middle to both sides, enabling the glue in the middle to spread to both sides more quickly. On the other hand, by restricting the width of the glue output channels 5 to be equal, the amount of glue flowing out of each glue output channel 5 is equal, so that the overall glue output of the glue application head is uniform, ensuring the glue application quality.

[0029] In this embodiment, the ways of passing through screw holes and locking with screws between the glue application base 1 and the first clamping member 22, between the limiting block 21 and the second clamping member 23, and between the first pressing block 31 and the second pressing block 32 are all conventional technical means in the art. Screws are drawn in the figure and corresponding components are marked, and will not be elaborated in this specific implementation manner.

[0030] In addition, it should be noted that for the specific embodiments described in this specification, the names of their respective parts and the like can be different. Any equivalent or simple changes made according to the structure, features, and principles described in the patent concept of the present invention are included in the protection scope of the patent of the present invention. Those skilled in the art of the present invention can make various modifications, supplements, or use similar ways to replace the specific embodiments described as long as they do not deviate from the structure of the present invention or exceed the scope defined by this claim book, and should all belong to the protection scope of the present invention.
