Description

Technical Field

[0001] This utility model relates to the technical field of labeling machine accessories, and in particular to a storage mold for automatically labeling plastic product labels. Background Technology

[0002] With the continuous improvement of industrial automation, automatic labeling equipment has been widely used in plastic product packaging lines due to its high efficiency and precision. As a key component of the automatic labeling system, the performance of the label storage mold directly affects the smoothness, stability, and final labeling quality of the labeling process. Its core function is to hold and support the roll of label paper and ensure that the label roll can be released smoothly and with low resistance during the labeling process.

[0003] However, existing label storage molds have significant shortcomings in structure and function, making it difficult to meet the flexibility requirements of modern production. Firstly, traditional storage molds typically employ a fixed-size disc structure with non-adjustable internal space and support structure. This means that a single mold can often only accommodate label rolls of a specific inner diameter and thickness. When different label specifications need to be changed on the production line, the machine must be stopped and the corresponding storage mold replaced, which is not only cumbersome and time-consuming but also reduces overall production efficiency and increases the purchase and management costs of the molds.

[0004] Secondly, traditional molds often use a solid disc with a large contact area to support and limit the label roll. This design results in a large contact area between the side of the label roll and the surface of the disc when the label roll rotates to release the label, thus generating significant rotational friction resistance. Excessive friction can easily cause unnecessary stretching of the label paper during traction, and may even cause problems such as label breakage, wrinkles, or inaccurate labeling, directly affecting the success rate of labeling and the appearance quality of the product.

[0005] Therefore, a storage mold for automatic labeling of plastic products is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0007] Therefore, one objective of this utility model is to provide a storage mold for automatically labeling plastic product labels, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0008] To achieve the above objectives, one embodiment of the present invention provides a storage mold for automatically labeling plastic product labels, including a tray body, a central column, and positioning holes. The central column is fixedly connected to the center of the front side of the tray body, and a plurality of mounting holes are provided on the edge of the tray body.

[0009] The surface of the central column is provided with a plurality of positioning holes, and a collar is installed at any of the positioning hole positions;

[0010] The outer surface of the collar is fixedly connected to several fixing plates, and tracks are provided on the fixing plates and the collar.

[0011] A fixed rod is movably connected in the track, and a washer is fixedly connected to the base of the fixed rod. The washer abuts against the back of the fixed plate or collar.

[0012] The outer surface of the fixing rod is threaded with fasteners, and the back of the gasket is movably connected with a guide post;

[0013] A screw rod is inserted into the outer surface of the collar, and the end of the screw rod is threaded into the positioning hole.

[0014] Preferably, the surface of the disc is coated with a polyethylene coating, and the disc is made of plastic.

[0015] The above technical solution involves placing the label roll within the space between the collar and the disc, with the label roll's frame fitted onto three guide posts. Because the distance between the collar and the disc is adjustable, and the outer surface of the collar is threaded to the positioning hole on the central post via a screw, the distance between the collar and the disc can be adjusted according to the thickness of the label roll, ensuring stable placement. Furthermore, the adjustable guide posts can accommodate label roll frames with different inner diameters.

[0016] The collar is not a traditional large disc structure, but has several fixed plates fixedly connected to its outer surface. This design reduces the contact area when the label roll rotates, thereby reducing the friction during rotation. This allows the label roll to rotate more smoothly during automatic labeling, ensuring the continuity and stability of labeling.

[0017] The fixing rod is movably connected to the track on the fixing plate and the collar. By adjusting the position of the fixing rod in the track, the distance between the fixing rod and the collar axis can be changed to accommodate label rolls of different sizes. The washer at the base of the fixing rod abuts against the back of the fixing plate or collar, and the fastener (hexagonal nut with washer) with threaded connection on the outer surface can fix the fixing rod in the required position, ensuring that the label roll will not wobble during rotation.

[0018] Preferably, in any of the above embodiments, the disc body and the central column are bonded together with adhesive, and the positioning holes are arranged in a linear array on the central column.

[0019] Preferably, in any of the above embodiments, the distance between the collar and the disc is adjustable, and the collar is fitted onto the outer surface of the central column.

[0020] The core design of the device is that this storage mold can accommodate label rolls with different inner diameters and thicknesses. By adjusting the distance between the collar and the disc, as well as the distance between the fixing rod and the collar axis, the installation requirements of various specifications of label rolls can be met, improving the versatility and flexibility of the equipment and reducing the hassle of changing molds due to different label roll specifications.

[0021] The collar uses a design with multiple fixed plates connected around its perimeter, instead of the traditional large disc structure. This significantly reduces the contact area when the label roll rotates, effectively reducing friction during rotation. This allows the label roll to rotate more smoothly during automatic labeling, reducing problems such as label stretching and breakage caused by excessive friction, and improving labeling quality and efficiency.

[0022] The fixing rod is movably connected to the fixing plate and collar via a track and secured by fasteners, ensuring the label roll remains stable during rotation and preventing wobbling or displacement. Meanwhile, the guide pillars are made of stainless steel, possessing high strength and stability, reliably supporting the label roll's frame and further guaranteeing the overall stability of the device.

[0023] Preferably, any of the above solutions includes at least three fixing plates, and the axial distance between the fixing rod and the collar is adjustable.

[0024] Preferably, the guide post is made of stainless steel, and the fastener is a washer-equipped hexagonal nut.

[0025] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0026] This automatic labeling storage mold for plastic products can accommodate label rolls with different inner diameters and thicknesses. By adjusting the distance between the collar and the disc, as well as the distance between the fixing rod and the collar axis, the installation requirements of various label roll specifications can be met, improving the versatility and flexibility of the equipment and reducing the hassle of changing molds due to different label roll specifications.

[0027] The collar uses a design with multiple fixed plates connected around its perimeter, instead of the traditional large disc structure. This significantly reduces the contact area when the label roll rotates, effectively reducing friction during rotation. This allows the label roll to rotate more smoothly during automatic labeling, reducing problems such as label stretching and breakage caused by excessive friction, and improving labeling quality and efficiency.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0036] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] like Figure 1-4 As shown, the storage mold for automatic labeling of plastic products includes a tray body 1, a central column 2, and positioning holes 3. The central column 2 is fixedly connected to the center of the front of the tray body 1, and several mounting holes are opened on the edge of the tray body 1.

[0038] The surface of the central column 2 is provided with several positioning holes 3, and a collar 4 is installed at any position of the positioning hole 3;

[0039] Several fixing plates 5 are fixedly connected to the outer surface of the collar 4, and rails 6 are provided on the fixing plates 5 and the collar 4;

[0040] A fixed rod 7 is movably connected in the track 6, and a gasket 8 is fixedly connected to the base of the fixed rod 7. The gasket 8 abuts against the back of the fixed plate 5 or the collar 4.

[0041] The outer surface of the fixing rod 7 is threaded with a fastener 9, and the back of the washer 8 is movably connected with a guide post 10.

[0042] A screw rod 11 is inserted into the outer surface of the collar 4, and the end of the screw rod 11 is threaded into the positioning hole 3.

[0043] Example 1: The surface of the disc body 1 is coated with a polyethylene coating, and the material of the disc body 1 is plastic. The disc body 1 and the central post 2 are bonded together with adhesive, and the positioning holes 3 are arranged in a straight line on the central post 2. The distance between the collar 4 and the disc body 1 is adjustable, and the collar 4 is fitted onto the outer surface of the central post 2. At least three fixing plates 5 are provided, and the axial distance between the fixing rod 7 and the collar 4 is adjustable. The guide post 10 is made of stainless steel, and the fastener 9 is a hexagonal nut with a washer.

[0044] Example 2: The label roll is placed in the space formed between the collar 4 and the disc 1, and the label roll frame is fitted onto three guide posts 10. Since the distance between the collar 4 and the disc 1 is adjustable, and the outer surface of the collar 4 is threaded to the positioning hole 3 on the central post 2 via a screw rod 11, the distance between the collar 4 and the disc 1 can be adjusted according to the thickness of the label roll, ensuring stable placement. Simultaneously, the adjustable guide posts 10 can accommodate label roll frames with different inner diameters.

[0045] The collar 4 is not a traditional large disc structure, but has several fixing plates 5 fixedly connected to its outer surface. This design reduces the contact area when the label roll rotates, thereby reducing the friction during rotation, allowing the label roll to rotate more smoothly during automatic labeling, ensuring the continuity and stability of labeling.

[0046] The fixing rod 7 is movably connected to the track 6 on the fixing plate 5 and the collar 4. By adjusting the position of the fixing rod 7 in the track 6, the distance between the fixing rod 7 and the axis of the collar 4 can be changed to accommodate label rolls of different sizes. The washer 8 at the base of the fixing rod 7 abuts against the back of the fixing plate 5 or the collar 4, and the fastener 9 (with washer hexagonal nut) with threaded connection on the outer surface can fix the fixing rod 7 in the required position to ensure that the label roll does not wobble during rotation.

[0047] The working principle of this utility model is as follows:

[0048] Select a plastic disc 1 with a polyethylene coating to ensure durability and corrosion resistance. Attach the center post 2 to the center of the front of the disc 1 using adhesive. The center post 2 has several positioning holes 3 arranged in a straight line. Select appropriate positioning holes 3 according to the thickness of the label roll to be used. Place the collar 4 on the outer surface of the center post 2 and thread it into the positioning holes 3 using a screw rod 11. Adjust the distance between the collar 4 and the disc 1 so that the distance is slightly greater than the thickness of the label roll. Place the label roll between the collar 4 and the disc 1, and fit the label roll's frame onto the guide post 10. The guide post 10 is made of stainless steel to ensure its strength and stability. Observe the dimensions of the label roll and move the fixing rod 7 within the track 6 on the fixing plate 5 and the collar 4. Adjust the distance between the fixing rod 7 and the axis of the collar 4 so that the fixing rod 7 fits tightly against the label roll, thus securing it. Then tighten the fastener 9 (hex nut with washer) to fix the fixing rod 7 in the right position, while ensuring that the washer 8 abuts against the back of the fixing plate 5 or the collar 4 to enhance the stability of the fixation.

[0049] Install the storage mold with the label roll installed onto the automatic labeling equipment, start the equipment, and the label roll begins to rotate under the drive of the equipment. Because multiple fixing plates 5 are connected around the collar 4, the friction during rotation is reduced, the label roll can rotate smoothly, and the label is accurately applied to the plastic product.

[0050] Compared with the prior art, the present invention has the following advantages:

[0051] This automatic labeling storage mold for plastic products can accommodate label rolls with different inner diameters and thicknesses. By adjusting the distance between the collar 4 and the disc 1, as well as the distance between the fixing rod 7 and the axis of the collar 4, the installation requirements of various specifications of label rolls can be met, improving the versatility and flexibility of the equipment and reducing the hassle of changing molds due to different label roll specifications.

[0052] The collar 4 uses a design with multiple fixing plates 5 connected around it, instead of the traditional large disc structure. This greatly reduces the contact area when the label roll rotates, thus effectively reducing friction during rotation. This allows the label roll to rotate more smoothly during automatic labeling, reducing problems such as label paper stretching and breakage caused by excessive friction, and improving labeling quality and efficiency.
