Description

Technical Field

[0001] The utility model relates to an imprint coating device. Background Art

[0002] When a user performs quilting, generally a simple side-drawing tool is used for manual line drawing, and then the sewing machine is controlled along the line for quilting. However, most of the manual line drawings cannot achieve beauty and uniformity. Powder sweeping can help the user accurately mark the sewing line on the fabric to ensure that the sewn pattern is accurate and unified and the line is smooth.

[0003] During the sewing process, powder sweeping usually refers to a process of coating an easy-to-clean powder on a prefabricated template, and the powder falls through the small holes pre-made on the template to form a certain pattern imprint on the fabric to facilitate sewing. The traditional operation method is that the user fixes the position of the prefabricated template, places it on the fabric, holds a brush dipped in powder and sweeps the powder back and forth on the template. After the fabric is coated with the imprint, the template is lifted and sewn according to the imprint. When workers produce in batches, the cumbersome operation of repeatedly dipping the powder slurry makes it time-consuming and laborious under the conditions of mass production. And when an individual handicraftsman performs quilting, how to prepare the powder and how to deal with the remaining powder also become a troublesome problem.

[0004] The Chinese invention patent application with the application number 201410513838.0 (publication number CN104223546A) discloses "An automatic powder sweeping device and method for denim cut pieces". This patent realizes automatic powder sweeping and distribution by a machine, and at the same time adopts a two-stack cloth three-station cyclic operation method to improve production efficiency. However, it is not possible to use this kind of automatic device in all cases, especially when an individual handicraftsman performs quilting. Therefore, from the perspective of applicability, it is still necessary to create an improved imprint coating device based on the most traditional hand-held brush method to solve the above problems. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide an imprint coating device that does not need to repeatedly dip the powder slurry, has a simple structure and wide applicability in view of the above technical status.

[0006] The technical solution adopted by the utility model to solve the above technical problem is: an imprint coating device, characterized in that it includes a roller assembly for coating the imprint, and the roller assembly includes

[0007] a cylinder bracket with both ends closed and powder outlets opened on the outer peripheral surface;

[0008] The powder outlet sleeve body is sleeved outside the cylinder support and at least covers the powder outlet on the side of the cylinder support, so as to form a powder storage cavity for storing powder inside the drum assembly. A plurality of small powder outlet channels are evenly distributed on the powder outlet sleeve body. Without external force applied to the powder outlet sleeve body, the powder outlet channels are closed. When the powder outlet sleeve body is subjected to external force extrusion, the powder outlet channels are opened to connect the powder storage cavity with the outside.

[0009] Preferably, the cylinder support includes a bottom end cover and a side frame. The bottom end cover is detachably installed at both ends of the side frame. Users can remove the bottom end cover at one end to fill the powder storage cavity with powder. In order to enhance the effect of extrusion powder discharge and prevent slipping between the powder outlet sleeve body and the side frame at the same time, the side frame includes two annular parts extending along the circumferential direction of the cylinder support, which are respectively distributed at both ends of the side frame. At least one convex rib extending along the axial direction is connected between the two annular parts, and the convex rib protrudes radially outward from the annular part.

[0010] Furthermore, the side frame further includes a plurality of annular ribs extending circumferentially in a ring shape. The annular ribs are distributed between the two annular parts. There are multiple convex ribs which intersect with the annular ribs to form a mesh, and the mesh holes are the powder outlets. During the rolling process of the drum assembly of the present utility model, the convex ribs extrude the powder outlet sleeve body so that the external force it receives meets the set value. The powder outlet channels on both sides of the extrusion point of the powder outlet sleeve body (i.e., both sides of the convex rib) are opened, and the powder in the powder storage cavity is released through the powder outlet and the powder outlet channels. After rolling over the convex rib, the external force received by the powder outlet sleeve body no longer meets the set value, and the powder outlet channels return to be closed. The powder that has not completely left the drum assembly returns to the powder storage cavity again, and the drum assembly continues to roll, and the movement of the powder repeats according to the above process.

[0011] The above-mentioned "set value" specifically refers to the intensity of the extrusion received by the powder outlet sleeve body, which is a critical value that can cause the powder outlet channels in the powder outlet sleeve body to conduct. The material, density and / or thickness of the powder outlet sleeve body, etc. determine the deformation ability of the powder outlet sleeve body, and these factors of the powder outlet sleeve body also determine the size of the above-mentioned set value.

[0012] Furthermore, the surface of the bottom end cover has elastic buckles extending towards the inside of the cylinder support, and the elastic buckles are buckled with the annular parts of the side frame, so that the bottom end cover can be detachably installed with the side frame.

[0013] In order to prevent powder from leaking out from the installation gap between the bottom end cover and the side frame, preferably, the powder outlet sleeve body is sleeved outside the side frame, and its two ends are folded inwards towards the side frame and filled in the installation gap between the bottom end cover and the side frame.

[0014] Preferably, the powder outlet sleeve is a cylindrical sponge, which is adaptively limited on the outer peripheral surface of the cylinder bracket. The sponge-like powder outlet sleeve is tightly fitted with the cylinder bracket and will not fall off randomly. When the sponge-like powder outlet sleeve is under external force extrusion, multiple dense pores in the sponge itself penetrate to form a small powder outlet channel.

[0015] Specifically, the sponge is made of foamed PU polyurethane, with a density range of 14-18 kg / m3, a thickness range of 4-6 mm, and a sponge flocking length range of 1-1.5 mm.

[0016] To facilitate powder sweeping, preferably, the marking coating device further includes a housing, the roller assembly is rotatably connected in the housing, and the housing includes a gripper portion.

[0017] Preferably, a rotating shaft is provided at the center of the outer surface of the bottom end cover. The housing has a "C"-shaped first clamping portion, and the rotating shaft is clamped into the first clamping portion of the housing through the "C"-shaped opening of the first clamping portion. In this structure, when the powder in the powder storage cavity is exhausted, the roller assembly can be easily removed and replaced with a new one.

[0018] Further, the housing includes an upper housing and a lower housing. The gripper portion and the first clamping portion are provided on the upper housing. The lower housing is detachably installed with the upper housing. The lower housing has a "C"-shaped second clamping portion, and the first clamping portion is clamped into the second clamping portion through the "C"-shaped opening of the second clamping portion.

[0019] Preferably, feet for supporting the marking coating device are provided at the bottom of the lower housing. The provision of feet facilitates the marking coating device to be placed upright on a table or other places.

[0020] Compared with the prior art, the powder of the present utility model can be directly stored in the powder storage cavity inside the roller assembly to achieve integrated storage. When the powder outlet sleeve is under external force extrusion that meets the set value, the powder outlet sleeve will deform and conduct the internal powder outlet channel, and the powder in the powder storage cavity will be automatically released through the conducted powder outlet channel. When used in cooperation with a template, the required marks can be accurately coated on the fabric. When the powder outlet sleeve is not under external force or the external force does not meet the set value, the powder outlet sleeve does not deform or only slightly deforms and is not sufficient to conduct the powder outlet channel, and the powder outlet channel is in a closed state, which can effectively prevent accidental powder leakage. The present utility model not only eliminates the cumbersome process of the user repeatedly dipping the powder slurry, but also has an operation method similar to that of a traditional brush, and is small in size, greatly improving the convenience of use, and is especially suitable for personal handicraftsmen.

[0026] The following further describes the present utility model in detail with reference to the embodiments of the accompanying drawings.

[0027] As Figures 1 to 5 shown, it is a preferred embodiment of an imprint coating device of the present utility model. This embodiment includes a drum assembly 2 and a housing 1. The drum assembly 2 can store and release powder, and is the main component for realizing the function of coating imprints. The housing 1 is disposed outside the drum assembly 2 and is used to accommodate and protect the drum assembly 2.

[0028] The structure of the drum assembly 2 is as Figure 3 shown, and it includes a cylinder bracket 2a and a powder outlet sleeve body 21 sleeved outside the cylinder bracket 2a. A hollow cavity is formed inside the drum assembly 2, that is, a powder storage cavity 24 for storing powder.

[0029] The cylinder bracket 2a includes a side frame 23 corresponding to the outer peripheral side of the cylinder and two bottom end caps 22 correspondingly installed at both ends of the side frame 23.

[0030] The side frame 23 includes two circumferentially extending annular portions 231, which are respectively located at the two ends of the side frame 23. At least one convex rib 232 extending in the axial direction is connected between the two annular portions 231. The convex rib 232 protrudes radially outward from the annular portion 231. Refer to Figure 3 . The side frame 23 further includes a circumferentially extending annular rib 233. There is at least one annular rib 233, which is disposed between the two annular portions 231. In this embodiment, there are multiple convex ribs 232 and annular ribs 233, and finally they are intertwined into a mesh, and the mesh holes thereof serve as powder outlet ports 234 for communicating the inside and outside of the cylinder bracket 2a.

[0031] The inner surface of the bottom end cap 22 has an elastic buckle 223 extending towards the inside of the cylinder bracket 2a. The elastic buckle 223 is buckled with the annular portion 231 of the side frame 23, so that the bottom end cap 22 can be detachably installed with the side frame 23. Refer to Figure 4。At the center of the outer surface of the bottom end cover 22, there is a rotating shaft 221 extending outward for installation with the outer shell 1.

[0032] The powder outlet sleeve body 21 is sleeved outside the cylinder support 2a, covering the entire side surface of the cylinder support 2a and the powder outlet 234 opened on the side surface. The powder outlet sleeve body 21 is evenly distributed with a plurality of fine powder outlet channels (since the powder outlet channels are too fine to be shown on the powder outlet sleeve body 21 in the figure). When no external force meeting the set value is applied to the powder outlet sleeve body 21, the powder outlet channels are closed. When the powder outlet sleeve body 21 is extruded by an external force meeting the set value, the powder outlet sleeve body 21 deforms to conduct the internal powder outlet channels, and then the powder storage cavity 24 is communicated with the outside.

[0033] In this embodiment, the powder outlet sleeve body 21 is a cylindrical sponge, which is adaptively limited on the outer peripheral surface of the cylinder support 2a. The sponge-like powder outlet sleeve body is tightly fitted with the cylinder support and will not fall off randomly. When the sponge-like powder outlet sleeve body 21 is in a state of being extruded by an external force, a plurality of dense fine holes in the sponge itself penetrate to form a fine powder outlet channel as described above. In actual implementation, the sponge is a foamed sponge, preferably made of PU polyurethane, with a density range of 14 - 18 kg / m 3 (the optimal value is 16 kg / m 3 ), the thickness range is 4 - 6 mm (the optimal value is 5 mm), and the sponge flocking length range is 1 - 1.5 mm (the optimal value is 1.25 mm). The sponge-made powder outlet sleeve body 21 is sleeved outside the side frame 23. The two ends of the powder outlet sleeve body 21 cover the ends of the side frame 23 and fold inward (i.e., into the powder storage cavity 24) of the side frame 23, so that the sponge-made powder outlet sleeve body 21 can fill the installation gap between the bottom end cover 22 and the side frame 23 to prevent powder from leaking out of the installation gap between the bottom end cover 22 and the side frame 23. As Figure 3 shown, the left end 21a of the powder outlet sleeve body 21 shows the structure of the end folding inward into the side frame 23. Since the sponge-made powder outlet sleeve body 21 is soft and can be folded randomly, as long as the overall length of the processed powder outlet sleeve body 21 is greater than the length of the side frame 23, during actual assembly, the two ends of the sponge-made powder outlet sleeve body 21 can be folded inward.

[0034] This embodiment further includes an outer shell 1 for installing the roller assembly 2. The outer shell 1 can be divided into an upper shell 11 and a lower shell 12. Please refer to Figure 5, the upper shell 11 has a first clamping portion 112 in a "C" shape. The rotating shaft 221 of the bottom end cover 22 is inserted into the first clamping portion 112 of the upper shell 11 from the "C" - shaped opening of the first clamping portion 112, so that the drum assembly 2 is rotatably connected within the outer shell 1. The first clamping portion 112 further includes a retaining ring 113 in a "C" shape. Correspondingly, the rotating shaft 221 of the bottom end cover 22 has an annular groove 222. The retaining ring 113 can partially enter the annular groove 222 to limit the horizontal shaking of the drum assembly 2. In addition, in order to facilitate the user to use the coating mark in this embodiment, the upper shell 11 is also provided with a gripping portion 111.

[0035] The lower shell 12 of this embodiment is detachably installed with the upper shell 11. Specifically, the lower shell 12 has a second clamping portion 122 in a "C" shape. The first clamping portion 112 of the upper shell 11 is inserted into the second clamping portion 122 from the "C" - shaped opening of the second clamping portion 122. The "C" - shaped second clamping portion 122 has two ends, and the two ends respectively extend towards opposite and away directions to form extension portions 123. The extension portions 123 expand the contact area between the lower shell 12 and the drum assembly 2, effectively reducing the horizontal shaking of the drum assembly 2. The bottom of the lower shell 12 is also provided with feet 121 for supporting the mark coating device, which can facilitate the upright placement of this embodiment.

[0036] The working principle of this embodiment:

[0037] First, install a bottom end cover 22 with the side frame 23, and the powder outlet sleeve 21 is sleeved on the side frame 23 to cover all the powder outlets 234; put the powder into the device from the end without installing the bottom end cover 22, and then install the other bottom end cover 22 with the side frame 23; then install the drum assembly 2 filled with powder with the upper shell 11, and then install the lower shell 12 with the upper shell 11. This embodiment is assembled and can be put into use at any time.

[0038] The user can directly obtain the assembled finished product. After removing the lower shell 12, the powder outlet sleeve 21 is exposed. In the non - working state, the powder outlet sleeve 21 is not extruded by external forces, and the powder outlet channels on the sponge - like powder outlet sleeve 21 are in a closed state.

[0039] When an imprint needs to be coated, the user holds the handle part 111 with the hand, squeezes and rolls the roller assembly 2 on the fabric covered with the template. During the rolling process, the convex rib 232 squeezes the sponge powder outlet body 21 so that the external force it receives meets the set value. The dense fine holes on both sides of the squeezed point of the powder outlet body 21 (i.e., both sides of the convex rib 232) will deform, and some of the fine holes will penetrate to form multiple through powder outlet channels (when the sponge is squeezed, some of the internal fine holes will penetrate with the deformation of the sponge). The powder in the powder storage cavity 24 is released through the powder outlet 234 and the powder outlet channels, and finally the corresponding imprint is coated on the fabric; after rolling over the convex rib 232, the external force received by the powder outlet body 21 no longer meets the set value, the powder outlet channels return to the closed state, and the powder that has not completely left the roller assembly 2 returns to the powder storage cavity 24 again. The roller assembly 2 continues to roll, and the movement of the powder repeats according to the above process.

[0040] When the powder in the powder storage cavity 24 is exhausted, the user removes the roller assembly 2 as a consumable and replaces it with a new roller assembly 2 filled with powder to continue using.
