Description

Technical Field

[0001] The invention relates to the field of die cutting, in particular to a device for adjusting the height of a material belt during material feeding and discharging in an automatic die cutting system. Background Art

[0002] The die-cutting machine is also called a die-cutting machine, a cutting machine, or a CNC punching machine. It is mainly used for die-cutting, creasing, hot stamping, laminating, and automatic waste discharge of some corresponding non-metallic materials, self-adhesive tapes, double-sided tapes, electronics, and mobile phone pads. The die-cutting machine uses steel knives, hardware molds, and steel wires to apply a certain amount of pressure through the stamping plate to roll and cut printed products or cardboard into a certain shape. It is an important equipment for post-printing packaging processing and molding. During the use of the die-cutting machine, the strip die-cutting raw materials will pass through the feed rack and feed table in turn, and finally enter the die-cutting device to complete die-cutting, creasing, hot stamping, or laminating. The material belt fixing shaft on the die-cutting machine table can fix the material belt, prevent the material belt from shifting left and right, and act as a buffer between the feed shaft and the machine table, so that the material belt is in a taut state. When general equipment is feeding and discharging materials, such as Figure 1 As shown, the height of the material belt 6 when it passes through the material belt fixing shaft 8 and enters the die-cutting machine 9 is fixed by the material belt fixing shaft 8 and cannot be adjusted. When the material belt 6 passes through the material belt fixing shaft 8, an unadjustable angle is generated between the feed shaft 7 and the plane of the die-cutting machine 6. When a relatively long or hard product 10 passes through the material belt fixing shaft 8, it is easy to cause the product 10 to warp (such as Figure 2 Different products and different base films have different peeling forces, which will also cause the products to warp to varying degrees. When they enter the die-cutting device, they will be uneven and prone to wrinkles, which will have an adverse effect on the entire die-cutting work. In addition, the die-cutting head on the die-cutting device cannot be replaced, resulting in different die-cutting machines being required for different die-cutting jobs, greatly reducing work efficiency and increasing work costs.

[0003] The existing solution is to add multiple additional material belt fixing shafts at the rising stage of the material belt 6 about to reach the material belt fixing shaft 8, thereby decomposing a large angle into multiple small angles and alleviating the degree of warping. However, since the added fixed shafts are also fixed at a certain point and cannot be adjusted, different products and different material belts have different requirements for the position of the fixed shaft when they are loaded onto the machine, which will cause repeated adjustments to the fixed shaft, thereby wasting more time and increasing costs. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the prior art and provide a device for adjusting the height of the material belt during feeding and discharging.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0008] Furthermore, the clamping wheel is arranged on the movable shaft, and the material belt passes through the movable shaft. The sliding of the material belt drives the roller on the movable shaft to roll, and the clamping wheel clamps both sides of the material belt to prevent the material belt from moving left and right.

[0009] Furthermore, the tops of the two vertical fixed shafts are connected to the fixed frame via springs, and the movable material belt fixed shaft is connected to the fixed frame.

[0010] Furthermore, a mounting groove is provided at the bottom of the horizontal fixed shaft, and the height adjustment knob is inserted into the mounting groove after passing through the fixing frame. The height adjustment knob is turned to push the compression spring of the movable material belt fixed shaft upward or downward to realize the up and down movement of the movable material belt fixed shaft.

[0011] Furthermore, the fixing frame includes a bottom horizontal frame and vertical frames arranged on both sides thereof, and the two vertical frames are in an inverted L shape, with the tops extending inwards, and are used to fix the tops of the springs.

[0012] Furthermore, a threaded hole is provided at the center of the bottom horizontal frame of the fixing frame, and the height adjustment knob passes through the threaded hole and is connected to the movable material belt fixing shaft.

[0013] Furthermore, the height adjustment knob is a bolt with external threads.

[0014] Furthermore, the material strip is led out from the feed shaft, passes through the movable material strip fixing shaft, and then enters the die-cutting machine through the fixed material strip fixing shaft for die-cutting.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1) The present invention designs a height-adjustable device, which is placed between the feed shaft and the material belt fixed shaft. By adjusting the height of the device, the angle of the material belt from the feed shaft to the material belt fixed shaft is changed, making the angle gentle. In addition, the height of the device is adjusted according to the characteristics of the product on the material belt, thereby adjusting the inclination angle of the material belt, changing the current situation that the material belt fixed shaft cannot be flexibly adjusted, reducing the degree of product warping, reducing the situation of product defects, and reducing time costs;

[0017] 2) The present invention designs a device for adjusting the height of the material belt during material feeding and unloading, and the position of the device is fixed by a fixing frame, and a movable material belt fixing shaft is connected to the fixing frame by a spring, and a height adjustment knob is provided at the bottom of the movable material belt fixing shaft. By rotating the height adjustment knob, the movable material belt fixing shaft can be pushed upward or downward to change the length of the compression or tension spring, and change the height of the movable material belt fixing shaft, thereby adjusting the height of the material belt passing through the movable material belt fixing shaft, thereby changing the feeding angle of the material belt. The structure is simple and the production cost is low. The upper and lower heights can be adjusted by rotating the bolts, and the operation is simple, which improves the production efficiency.

[0018] 3) The device of the present invention adopts a structural design of an outer fixed frame and an inner movable frame. The fixed frame and the movable frame are nested rectangular frame structures, which ensures the stability of the device. The inner and outer frames are connected by springs. While ensuring the stability of the up and down movement of the inner movable frame, the operating boundary of the inner movable frame is improved, and the applicability is wider.
