Description

Technical Field

[0001] This utility model relates to an apparatus for auxiliary printing, and more particularly to a simple screen printing apparatus suitable for prototyping packaging carton blanks. Background Technology

[0002] In the packaging carton manufacturing industry, patterns are pre-printed on the carton blank to create samples and test molds for finished cartons with different designs, typically using screen printing. Currently, screen printing samples on the carton blank usually require specialized equipment to ensure printing accuracy and efficiency. Existing technology for printing on carton blanks often suffers from insufficient adjustment flexibility, making it difficult to adapt to the printing needs of blanks of different sizes. This often necessitates custom-made tooling for specific dimensions, resulting in poor equipment versatility. Furthermore, the fixing structure of the printing frame generally lacks stability, easily shifting during operation, affecting printing positioning accuracy and increasing the scrap rate.

[0003] Traditionally, printing is done by hand using the screen printing frame during proofing, resulting in poor accuracy. To address this, auxiliary fixing devices are used to position the screen printing frame. However, in terms of ease of operation, traditional devices often employ complex locking mechanisms for their adjustment components, requiring specialized tools and exhibiting significant frictional resistance during adjustment, making positional adjustments time-consuming and laborious. While some devices offer basic adjustment functions, they lack effective lubrication and anti-slip designs, leading to adjustment jams or component wear after prolonged use, reducing work efficiency and shortening the device's lifespan. Furthermore, the overall structural strength of existing devices is insufficient, making them prone to deformation during frequent loading, unloading, and adjustments, further affecting the stability of printing accuracy.

[0004] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a simple screen printing device suitable for prototyping packaging carton blanks, so as to make it more industrially valuable. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a simple screen printing device suitable for prototyping packaging carton blanks.

[0006] This utility model discloses a simple screen printing device suitable for prototyping packaging carton blanks, comprising a docking carrier plate, wherein: the docking carrier plate is T-shaped; an X-axis adjustment component is installed on one side of the horizontal plate of the docking carrier plate, and a Y-axis adjustment component is installed on the other side of the vertical plate of the docking carrier plate; fastening mechanisms are distributed on the Y-axis adjustment components, and printing frames are connected to the fastening mechanisms; the fastening mechanisms include a limiting groove, and several locking components are installed on the limiting groove, the end faces of the locking components contacting the printing frames; the X-axis adjustment component includes a horizontal mounting plate and a limiting baffle, and an X-axis adjustment groove is formed on the horizontal mounting plate; the Y-axis adjustment component includes a vertical mounting plate, and a Y-axis adjustment groove is formed on the vertical mounting plate; it also includes a main locking screw and a secondary locking screw, which pass through the X-axis adjustment groove and the Y-axis adjustment groove respectively and are connected to the docking carrier plate.

[0007] Furthermore, in the aforementioned simple screen printing device for prototyping packaging carton blanks, the nuts of the main locking screw and the auxiliary locking screw are both hexagonal, and the inner walls of the X-axis adjustment groove and the Y-axis adjustment groove are fitted with POM lubricating strips.

[0008] Furthermore, in the aforementioned simple screen printing device for prototyping packaging carton blanks, the cross-section of the limiting clamping groove is rectangular, and its inner wall is fixed with silicone anti-slip stickers.

[0009] Furthermore, in the aforementioned simple screen printing device for prototyping packaging carton blanks, the locking component is a locking bolt with a hand-held knob at its end, and the surface of the hand-held knob is covered with anti-slip textures.

[0010] Furthermore, in the aforementioned simple screen printing device for prototyping packaging carton blanks, a handle is fixed to the fastening mechanism, and the handle is covered with a rubber anti-slip layer.

[0011] Furthermore, in the aforementioned simple screen printing device for prototyping packaging carton blanks, the back of the docking carrier plate is provided with reinforcing ribs.

[0012] Furthermore, in the aforementioned simple screen printing device suitable for prototyping packaging carton blanks, the edges of the docking carrier plate are provided with rounded chamfers.

[0013] Furthermore, in the aforementioned simple screen printing device suitable for prototyping packaging carton blanks, a plurality of anti-slip grooves are distributed on one side of the printing frame.

[0014] By means of the above solution, this utility model has at least the following advantages:

[0015] 1. Through the sliding adjustment structure of the X-axis and Y-axis adjustment components, combined with the fixing function of the main and auxiliary locking screws, the position can be flexibly adjusted according to the printing requirements of different specifications of packaging carton blanks, achieving adaptation to blanks of various sizes and improving the versatility of the device. During use, no manual support is required, resulting in more accurate positioning.

[0016] 2. The fastening mechanism initially limits the printing frame by using a rectangular limiting groove. Combined with the friction enhancement effect of the silicone anti-slip pad and the tight fixing of the locking component, it can effectively prevent the printing frame from shifting during operation and ensure the accuracy of the printing position.

[0017] 3. Each adjustment component uses hexagonal nuts to accommodate common tools. The locking assembly is equipped with a hand knob with anti-slip texture, and the POM lubricating strip in the adjustment groove reduces sliding resistance. Combined with the rubber anti-slip design of the handle, it makes the operation of adjusting the position of the device and loading and unloading the printing frame easier and more labor-saving, thus improving work efficiency.

[0028] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0029] like Figure 1 This invention relates to a simple screen printing device suitable for prototyping packaging carton blanks. The device is based on a docking carrier plate 1 as its fundamental support structure. The docking carrier plate 1 is T-shaped, and its structural design allows it to be fixed to the mounting base of the screen printing equipment, while providing a stable installation reference for the subsequent installation of various adjustment components and fastening mechanisms. To accommodate the screen printing area distribution of different packaging carton blanks, an X-axis adjustment component is installed on one side of the transverse plate of the docking carrier plate 1. This component includes a horizontal mounting plate 4 and a limiting baffle 5. The horizontal mounting plate 4 is initially connected to the transverse plate of the docking carrier plate 1 by bolts. An X-axis adjustment groove 6 is provided on the horizontal mounting plate 4, extending along the length of the horizontal mounting plate 4, for adjusting the position of the X-axis adjustment component in the transverse direction. Meanwhile, the limiting baffle 5 is vertically fixed to the side of the horizontal mounting plate 4 away from the end of the transverse plate of the docking carrier plate 1. During implementation, the height of the limiting baffle 5 is slightly higher than the thickness of the horizontal mounting plate 4, which can act as a stop when the X-axis adjustment component is adjusted to its limit position, preventing the X-axis adjustment component from slipping off the horizontal plate of the docking carrier plate 1. Furthermore, the X-axis adjustment component is equipped with a main locking screw 9, which passes through the X-axis adjustment groove 6 and is threadedly connected to the horizontal plate of the docking carrier plate 1. Tightening the main locking screw 9 fixes the X-axis adjustment component in the adjusted position, while loosening it allows the X-axis adjustment component to slide along the X-axis adjustment groove 6 to adjust its position. Moreover, the nut of the main locking screw 9 has a hexagonal structure, which is compatible with commonly used wrenches, making it convenient for operators to tighten and loosen the main locking screw 9 using a wrench. In addition, POM lubricating strips are attached to the inner wall of the X-axis adjustment groove 6 to reduce the frictional resistance when the main locking screw 9 slides within the X-axis adjustment groove 6, making the X-axis position adjustment process smoother and preventing wear on the inner wall of the X-axis adjustment groove 6 due to long-term sliding. During assembly, the POM lubricating strip can be adhered to the inner wall of the X-axis adjustment groove 6 using strong adhesive. After adhesion, the POM lubricating strip and the inner wall of the X-axis adjustment groove 6 are completely flush, with no obvious gaps. This avoids unnecessary lifting and will not affect the use of the X-axis adjustment groove 6.

[0030] According to a preferred embodiment of this utility model, a Y-axis adjustment component is also installed on the other side of the docking carrier plate 1. Specifically, the Y-axis adjustment component includes a longitudinal mounting plate 7, with a limiting groove 3 extending from one side of the longitudinal mounting plate 7. Simultaneously, a Y-axis adjustment groove 8 is provided on the longitudinal mounting plate 7, extending along the Y-axis direction of the longitudinal mounting plate 7, for adjusting the position of the Y-axis adjustment component in the longitudinal direction. Furthermore, a secondary locking screw 10 is provided corresponding to the Y-axis adjustment component, passing through the Y-axis adjustment groove 8 and threadedly connected to the longitudinal plate body of the docking carrier plate 1. Thus, by tightening the secondary locking screw 10, the Y-axis adjustment component can be fixed in the adjusted position; by loosening the secondary locking screw 10, the Y-axis adjustment component can be pushed to slide along the Y-axis adjustment groove 8 to adjust its position. During implementation, the nut of the secondary locking screw 10 also has a hexagonal structure, consistent with the nut structure of the main locking screw 9, facilitating operation by a wrench. Furthermore, the inner wall of the Y-axis adjustment groove 8 is also fitted with POM lubricating strips to ensure the smoothness of the Y-axis adjustment component during sliding and the wear resistance of the Y-axis adjustment groove 8.

[0031] Furthermore, to facilitate a stable connection between the printed frame 2 and the device after installation, this invention includes a fastening mechanism on the longitudinal mounting plate 7 of the Y-axis adjustment component. This fastening mechanism connects to the printed frame 2 and securely fixes it to the device. Specifically, the fastening mechanism includes a limiting groove 3 with a rectangular cross-section. The internal dimensions of the limiting groove 3 are adapted to the edge dimensions of the printed frame 2, allowing the edge of the printed frame 2 to fit precisely into the limiting groove 3. Simultaneously, a silicone anti-slip sticker is fixed to the inner wall of the limiting groove 3. The silicone anti-slip sticker is made of highly elastic silicone material and is adhered to the inner wall of the limiting groove 3 using double-sided adhesive. The silicone anti-slip sticker is 1-2mm thick, and after adhesion, its surface is flush with the inner wall of the limiting groove 3, increasing the friction between the printed frame 2 and the inner wall of the limiting groove 3, preventing the printed frame 2 from shifting laterally or longitudinally within the limiting groove 3. To facilitate locking, several locking components 11 are installed on both sides of the limiting groove 3. These locking components 11 are locking bolts, spaced apart along the height of the limiting groove 3. During implementation, the distance between adjacent locking bolts is 3-5 cm to ensure even distribution of the fixing force on the printing frame 2. The locking bolts are threaded to the side walls of the limiting groove 3, and their end faces can contact the side of the printing frame 2 embedded in the limiting groove 3. By tightening the locking bolts, the end faces of the locking bolts can be tightly pressed against the printing frame 2, further fixing the printing frame 2 within the limiting groove 3. Furthermore, a hand-held knob is provided at the end of the locking bolt. The hand-held knob and the locking bolt are integrally formed, and the surface of the hand-held knob has anti-slip textures. For ease of implementation, the anti-slip texture is a strip-shaped groove evenly distributed along the circumference of the handheld knob. The groove depth is 0.5-1mm, which can increase the friction between the hand and the handheld knob, allowing the operator to adjust the position of the locking bolt by simply turning the handheld knob without the need for tools.

[0032] In practical implementation, a handle 12 is fixed to the outer wall of the limiting groove 3 of the fastening mechanism. The handle 12 has a U-shaped structure, and both ends of the handle 12 are fixedly connected to the upper end of the limiting groove 3 by welding. The weld is polished and there are no obvious weld beads. At the same time, the surface of the handle 12 is covered with a rubber anti-slip layer, which is made of aging-resistant nitrile rubber material and is applied to the surface of the handle 12 by injection molding. The thickness of the rubber anti-slip layer is 2-3mm, and its surface has a fine textured surface, which can improve the comfort of the operator when holding the handle 12 and prevent slippage when the hands are sweaty. Furthermore, reinforcing ribs are distributed on the back of the docking carrier plate 1. Specifically, the reinforcing ribs are strip steel plates, which are spaced along the length of the transverse and longitudinal sections of the docking carrier plate 1. The thickness of the reinforcing ribs is 3-4mm, and they are fixed to the back of the docking carrier plate 1 by welding, which can effectively improve the structural strength of the docking carrier plate 1 and prevent the docking carrier plate 1 from deforming due to stress during long-term use.

[0033] Furthermore, the edges of the docking carrier plate 1 are rounded with chamfers. During processing, the radius of the chamfers is 1-2mm, which can be formed by lathe grinding. This eliminates sharp edges of the docking carrier plate 1, preventing operators from being scratched during installation or adjustment. Simultaneously, several anti-slip grooves are distributed on one side of the printing frame 2. Specifically, the anti-slip grooves are rectangular, evenly distributed along the length of the printing frame 2, with a depth of 1-1.5mm and a width of 2-3mm. This facilitates a stable connection between the printing frame 2 and the limiting clamping groove 3, preventing displacement and ensuring printing accuracy.

[0034] The working principle of this utility model is as follows: When using this device, first loosen the main locking screw 9 according to the size of the packaging carton blank, adjust the position of the X-direction adjusting component along the X-direction adjusting groove 6, and tighten the main locking screw 9 to fix it in place. During this period, the main locking screw 9 can be used to connect with the external lifting bracket to achieve suspended installation, which can be conveniently laid out by conforming to the height of the printing platform where the carton blank is located.

[0035] Then, the printing frame 2 is inserted into the limiting groove 3 of the fastening mechanism, and the end face of the locking bolt is pressed against the printing frame 2 by turning the hand knob of the locking assembly 11, thus completing the fixing of the printing frame 2.

[0036] Next, loosen the secondary locking screw 10 and adjust the position of the Y-axis adjusting component and fastening mechanism along the Y-axis adjusting groove 8 so that the printing frame 2 is exactly at the upper end of the area to be printed. After adjusting, tighten the secondary locking screw 10 to fix it.

[0037] Of course, during this period, fine adjustments can be made using the X-axis adjustment component to ensure accurate printing position.

[0038] Then, screen printing can be performed on the packaging carton blank. During implementation, the printing frame 2 can be replaced in batches according to the actual number of printing coatings. It should be noted that the printing frame 2 used in this utility model is an integral frame with screen printing directly adapted to the pre-reserved printing area.

[0039] Ultimately, single-layer or multi-layer printing proofing can be achieved according to actual proofing needs.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
