Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a precisely positioned self-adhesive label production mold. Background Art

[0002] Self-adhesive labels, also known as self-adhesive labels, instant stickers, pressure-sensitive paper, etc., are a kind of label material with self-adhesive properties. In the production process of self-adhesive labels, the use of molds is a crucial link. Among them, the knife die, as a common product in the die-cutting industry, plays an indispensable role. The knife die, that is, the mold for punching and cutting products, is an indispensable post-printing processing material in the subsequent processing of printed products. In the production of self-adhesive labels, the knife die is mainly used to punch out the shape of the required die-cut product to ensure that the self-adhesive label can be cut into the preset shape and size.

[0003] The utility model patent with the authorization announcement number CN217618367U discloses a precisely positioned laser knife die, which includes a base, support frames are fixedly installed on both sides of the upper end surface of the base, a pair of mounting boxes are fixedly installed on the top of the support frames, mounting blocks are fixedly installed at the four corners of the bottom of the base, the bottom of the mounting blocks are embedded with bearings, and sleeves are installed inside the bearings, the bottom of the sleeves are threadedly connected to threaded rods, the bottom of the threaded rods are welded with universal balls, and the outer sides of the universal balls are equipped with feet, and the feet are made of rubber. This precisely positioned laser knife die, through the coordinated use of sleeves, bearings and threaded rods, is convenient for users to adjust the angle of the base. The user rotates the sleeve to displace the sleeve on the threaded rod, and then rotates the sleeves at different corners to make the position of the base horizontal, which is convenient for the laser to unify the ablation depth of the knife die body, which is beneficial to the installation of the blade in the later stage;

[0004] Although the precisely positioned laser cutting die can level the base, the device still has the following problems in actual use: during processing, the raw material is placed on top of the cutting die, and the raw material lacks an effective positioning and limiting structure, which can easily lead to the problem of raw material deviation affecting the processing size. In view of this, we propose a precisely positioned self-adhesive label production mold. Utility Model Content

[0005] The purpose of the utility model is to provide a precisely positioned self-adhesive label production mold to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The die for producing self - adhesive labels with precise positioning includes a die cutter. Multiple cutting tools are fixed on the top of the die cutter. Multiple sliding grooves are opened at both the left and right ends of the die cutter; at the front and rear ends of the bottom of the die cutter, bases are fixed. At both ends of the base, threaded rods are thread - connected. At the bottom end of the threaded rod, a cushion block is rotatably installed; at the front - end groove of the top of the die cutter, a horizontal bubble is installed.

[0008] A positioning part is installed at the bottom of the die cutter. The positioning part includes a housing fixed to the bottom of the die cutter. Inside the opening of the housing, a double - headed lead screw is rotatably installed. On the outer wall of the housing, a motor for driving the double - headed lead screw to rotate is installed; at both threaded parts of the two ends of the double - headed lead screw, connection blocks are thread - connected. At both ends of the connection block, connecting plates are hinged. At the end of the connecting plate, hinge seats are hinged. Between adjacent hinge seats, a horizontally movable cross beam is fixed; multiple through - grooves are opened on the cross beam. Inside the through - grooves, sliders are slidably installed. At the center of the slider, a positioning rod is coaxially fixed. The top and bottom ends of the positioning rod pass through the cross beam, and the top end of the positioning rod is slidably connected with the sliding groove; a spring is also sleeved on the positioning rod, and the top end of the spring abuts against the bottom of the slider.

[0009] As a preferred technical solution of the present utility model, at the top end of the threaded rod, an adjusting screw is coaxially key - connected, and multiple anti - slip grooves are opened on the outer wall of the adjusting screw.

[0010] As a preferred technical solution of the present utility model, the cross - sectional shape of the housing is in the shape of a square frame, and the housing is fixedly connected to the die cutter by bolts.

[0011] As a preferred technical solution of the present utility model, the overall shape of the base is convex, and the base is fixedly connected to the die cutter by bolts.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. Through the positioning part: the motor drives the double-headed screw to rotate. With the rotation of the double-headed screw, the beams on both sides move relative to each other synchronously. The beams also drive the positioning rods on both sides to move relative to each other synchronously. Under the action of the positioning rods, the self-adhesive label raw material can be positioned, thereby preventing the problem of affecting the processing accuracy due to the deviation of the raw material placement; at the same time, when the cutting operation is carried out, when the positioning rod is subjected to pressure from above, the positioning rod can move downward, thereby not hindering the cutting operation of the raw material; this design can position and limit the self-adhesive label during the cutting process of the self-adhesive label, thereby ensuring the processing accuracy of the mold for the self-adhesive label.

[0017] 2. The base and level bubble are set to facilitate the adjustment of the levelness of the die cutter, thus avoiding the problem of insufficient flatness of the die cutter affecting the processing accuracy of the self-adhesive label. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] This embodiment provides a technical solution:

[0029] Please refer to Figures 1-6 As shown, the die-cutting sticker production mold with precise positioning includes a die mold 1. A plurality of cutting tools 13 are fixed on the top of the die mold 1, and a plurality of sliding grooves 10 are opened at both the left and right ends of the die mold 1; at the front and rear ends of the bottom of the die mold 1, bases 11 are fixed. At both ends of the base 11, threaded rods 12 are threadedly connected, and a cushion block 122 is rotatably installed at the bottom end of the threaded rod 12; a horizontal bubble 14 is installed at the front-end groove of the top of the die mold 1; a positioning part 2 is installed at the bottom of the die mold 1. The positioning part 2 includes a housing 20 fixed to the bottom of the die mold 1. A double-headed screw rod 22 is rotatably installed in the opening of the housing 20, and a motor 21 for driving the double-headed screw rod 22 to rotate is installed on the outer wall of the housing 20; at both ends of the double-headed screw rod 22, connecting blocks 23 are threadedly connected. At both ends of the connecting block 23, connecting plates 24 are hinged, and hinge seats 25 are hinged at the ends of the connecting plates 24. A horizontally movable cross beam 26 is fixed between two adjacent hinge seats 25; a plurality of through grooves 261 are opened on the cross beam 26, and sliders 27 are slidably installed in the through grooves 261. A positioning rod 28 is coaxially fixed at the center of the slider 27. The top and bottom ends of the positioning rod 28 pass through the cross beam 26, and the top end of the positioning rod 28 is slidably connected with the sliding groove 10; a spring 29 is also sleeved on the positioning rod 28, and the top end of the spring 29 abuts against the bottom of the slider 27.

[0030] In this embodiment, an adjusting screw 121 is coaxially key-connected to the top end of the threaded rod 12, and a plurality of anti-slip grooves are opened on the outer wall of the adjusting screw 121. This design enables the user to precisely adjust the position of the threaded rod 12 by rotation, thus facilitating the leveling of the die mold 1; the design of the anti-slip grooves enhances the holding stability of the adjusting screw 121 and prevents slipping during the adjustment process.

[0031] In this embodiment, the cross-sectional shape of the housing 20 is in the shape of a square frame, and the housing 20 is fixedly connected to the die mold 1 by bolts. The square-frame cross-sectional shape provides sufficient space to accommodate and protect the internal mechanical components; the bolt connection method ensures the firm connection between the housing 20 and the die mold 1, prevents loosening and accidental separation, and guarantees the overall stability and safety of the equipment.

[0032] In this embodiment, the overall shape of the base 11 is convex, and the base 11 is fixedly connected to the die 1 by bolts. The convex design of the base 11 is beneficial to enhancing the stability of the device and preventing sliding or tilting during use. The bolt connection method ensures a tight connection between the base 11 and the die 1, improving the stability and reliability of the entire structure.

[0033] In this embodiment, the overall shape of the slider 27 is rectangular, and the size of the slider 27 is adapted to the size of the through slot 261. This design enables the slider 27 to slide smoothly within the through slot 261, ensuring the smoothness of the movement.

[0034] In this embodiment, the overall shape of the cushion block 122 is frustum-shaped, and the cushion block 122 is made of rubber. The frustum-shaped design of the cushion block 122 can provide a larger contact area, increasing the friction between the cushion block 122 and the contact surface and preventing sliding. The rubber material has excellent anti-slip, shock-absorbing, and buffering properties, which can effectively reduce the vibration and noise of the device during operation while protecting the contact surface from damage.

[0035] In this embodiment, the cross-sectional shape of the cross beam 26 is rectangular, and the top end of the cross beam 26 is in contact with the bottom end of the die 1. The contact design between the cross beam 26 and the bottom end of the die 1 ensures a tight connection and support between the two, guaranteeing the smoothness and stability of the horizontal movement of the cross beam 26.

[0036] It should be added that the thread winding directions at both ends of the double-headed lead screw 22 in this embodiment are opposite. When the double-headed lead screw 22 rotates, the connecting blocks 23 on both sides can move correspondingly synchronously, thereby facilitating the adjustment of the positions of the cross beams 26 and the positioning rods 28 on both sides.

[0037] It is worth noting that the motor 21 involved in this embodiment is an existing conventional technology and will not be elaborated here.

[0038] During specific use, the operator first turns on the power supply of the motor 21. The motor 21 starts to work, and the output shaft of the motor 21 rotates to drive the double-headed lead screw 22 to rotate. As the double-headed lead screw 22 rotates, the connecting blocks 23 on both sides move synchronously relative to each other. The connecting blocks 23 simultaneously drive the connecting plates 24 on both sides to move synchronously relative to each other. The connecting plates 24 simultaneously drive the cross beams 26 on both sides to move synchronously relative to each other. The cross beams 26 simultaneously drive the multiple positioning rods 28 to slide horizontally along the chute 10. When the positioning rods 28 move to the appropriate positions, the operator stops the power supply of the motor 21. Finally, the operator covers the raw material between the positioning rods 28 on both sides of the top of the die 1, and then the raw material of the self-adhesive label can be cut.

[0039] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and the above embodiments and the descriptions in the specification are only preferred examples of the present utility model, which are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
