Description
Technical Field
[0001] This utility model relates to the field of transfer film technology, and in particular to a die and die holder for a flatbed creasing and tangling machine. Background Technology
[0002] Flatbed creasing and cutting machines are widely used in the forming and processing of cartons and packaging boxes. The dies used in flatbed creasing and cutting machines are mainly made of wood, plastic, iron or aluminum, and acrylic, but the most common type is the wood die. A wood die is made by cutting a groove in a piece of wood of a certain thickness according to the size of the blade, and then embedding the blade into it. Traditional dies use a one-piece wood grooved blade embedding structure, which has the following drawbacks:
[0003] (1) Poor compatibility: Each die set is only compatible with a single product shape. Switching models requires replacing the entire die template, which takes a long time.
[0004] (2) Low reuse rate: The blade layout cannot be adjusted after the wooden board is grooved, resulting in a high scrap rate;
[0005] (3) Storage damage: Stacked storage can easily lead to blade deformation and foam strip falling off.
[0006] Some existing technologies employ magnetic blade adsorption, but insufficient magnetic force causes blade displacement during processing, affecting accuracy. Therefore, there is an urgent need for a solution that can be quickly adjusted and supports the storage of multiple dies. This invention proposes a die and die holder for a flatbed creasing and tangling machine. Summary of the Invention
[0007] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a die and die holder for a flat pressing creasing and tangling machine, thereby solving the problems of poor die compatibility, low reuse rate and storage damage.

One side of the die template is provided with a blade assembly, which includes multiple blades arranged to form the desired shape of the product. The blades are attached to the die template with epoxy resin.
[0010] An inner buffer strip is provided on the inner side of the blade, and an outer buffer strip is provided on the outer side of the blade. The inner and outer buffer strips are attached one by one along the periphery of the blade on the inner and outer rings, respectively, thereby forming a blade groove.
[0011] The top of the die template has two through holes, one on the left and one on the right. A locking post is installed through each through hole to hold the die template on the die holder.
[0012] Furthermore, the gaps between adjacent inner buffer strips are staggered with the gaps between adjacent outer buffer strips.
[0013] Furthermore, both the inner and outer buffer strips are made of foam rubber.
[0014] Furthermore, the inner buffer strip is made of high-viscosity silicone; the outer buffer strip is made of high-elasticity polyurethane foam.

[0018] The inverted assembly includes an inverted plate, which is mounted on a connecting rod. The shape of the inverted plate matches the body of the die holder, and multiple inverted units are fixed below the bottom surface of the inverted plate.
[0019] The inverted unit includes a hollow inverted square tube. The top surface of the inverted square tube is fixed to the bottom surface of the inverted plate. The bottom surface of the inverted square tube has an opening groove facing downwards, forming a T-shaped long groove. The width of the opening groove matches the die template, and the length extends through the inverted plate. The top of the die template with a retaining post is inserted into the inverted square tube, and the front and rear sections of the retaining post are hung on the inverted square tube. The die template is inverted from the opening groove.
[0020] Furthermore, the die holder body is a cuboid frame structure, the inverted plate is a rectangular plate that matches the die holder body, and multiple parallel inverted units are fixed below the bottom surface of the inverted plate.
[0021] Furthermore, the die holder body is a double-layer disc-type rotating frame supported by four columns, and the rotating frame is driven by a stepper motor; each layer of the rotating frame is provided with an inverted assembly, the inverted assembly includes a disc-shaped inverted plate that matches the die holder body, the inverted plate is provided with at least 6 suspension positions, each suspension position is provided with an inverted unit, and the inverted units are arranged radially and equidistantly around the center of the inverted plate.
[0022] Furthermore, a V-shaped groove is provided on each of the left and right sides of the inverted square tube, and several grooves are provided on the top surface of the inverted square tube to enhance its supporting strength.
[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0029] (4) The die holder supports multi-layer suspension, increases storage capacity, reduces the floor space occupied by die storage, solves problems such as inefficient die changing, storage damage, fixing failure and rough management of traditional die, and significantly improves the flexible production capacity of the creasing and cutting machine.
