Description

Technical Field

[0001] This utility model relates to the field of adjustment device technology, and in particular to a flatbed die-cutting adjustment device. Background Technology

[0002] The working principle of a flatbed die-cutting machine can be summarized as follows: the transmission system drives the pressure plate to move downwards, covering the printed material to be processed placed between the template and the worktable. The huge pressure generated between the pressure plate and the template causes the printed material to deform, thereby accurately cutting out the finished product of the required shape and size. In this process, the movement trajectory of the pressure plate can be divided into two types according to the design: swinging around a fixed hinge or swinging first and then translating under the drive of a connecting rod. This ensures the accuracy and stability of the die-cutting effect. Flatbed die-cutting machines are widely used in printing, packaging, labeling and other industries due to their simple structure, convenient operation, strong adaptability and high production efficiency. They are especially suitable for small-batch and diversified production needs.

[0003] The feeding plate of this die-cutting machine drives the cardboard to feed one by one through rollers in its groove. In order to ensure that the cardboard remains stable when it is being fed, baffles are set at both ends of the top of the feeding plate. The baffles slide on the feeding plate through sliding components, thereby adjusting the spacing and adapting to the width of the cardboard. After adjustment, the two baffles are fixed by bolts and other fasteners.

[0004] While this adjustment method is structurally simple, it adjusts the spacing between the baffles individually. This means that although the spacing between the two baffles can match the width of the cardboard after adjustment, the center point of the cardboard feeding area and the center point between the baffles need to be readjusted to achieve alignment. Different batches of cardboard have different sizes, and although the spacing between the baffles needs to be adjusted after the size changes, the above method requires not only adjusting the spacing of the baffles but also aligning the center point, which increases the number of work steps, affects work efficiency, and makes the entire adjustment method difficult to simplify. Utility Model Content

[0005] The main purpose of this utility model is to provide a flatbed die-cutting adjustment device, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A flatbed die-cutting adjustment device includes a paper feeder with an adjustment mechanism on its front side and baffle mechanisms at both ends of the top of the paper feeder. Several roller grooves are carved into the paper feeder, and paper feed rollers are installed inside each roller groove. A long sliding groove is carved at the top end of each roller groove away from the adjustment mechanism. The baffle mechanism includes a baffle plate, and a long slider is fixed to the bottom of the baffle plate near the long sliding groove. The long slider is inserted into and slidably connected to the long sliding groove. A side bracket is fixed to the front side of the baffle plate near the adjustment mechanism, and a double-cylinder component is fixed to the bottom of the side bracket. The adjustment mechanism includes two ear plates, with an adjusting rod at the front end between the ear plates and a fixing rod at the rear end between the ear plates. One end of the adjusting rod is rotatably connected to one ear plate, and the other end of the adjusting rod is rotatably connected to the other ear plate after passing through it. A handle is fixed to the end of the adjusting rod passing through the ear plate. Threaded teeth are provided on the outer walls of both ends of the adjusting rod located between the two ear plates.

[0008] Preferably, one end of each of the two double-cylinder components of the two baffle mechanisms is respectively sleeved on both ends of the adjusting rod and connected to it with an unknown threaded connection, and the other end of each of the two double-cylinder components of the two baffle mechanisms is respectively sleeved on both ends of the fixed rod and slidably connected to it.

[0009] Preferably, the threaded teeth at both ends of the adjusting rod have opposite directions.

[0010] Preferably, a support block is provided at the position between the adjusting rod and the fixed rod, the fixed rod passes through the support block and is fixedly connected, and the adjusting rod passes through the support block and is rotatably connected by a bearing.

[0011] Preferably, the ear plate is provided with bolts, and the ear plate is detachably connected to the paper feed plate by the bolts.

[0012] Preferably, the bottom of each baffle located parallel to the paper feed roller is chiseled with an arc-shaped groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The two cylindrical components of the baffle mechanism are slidably connected to the fixed rod and threadedly connected to the threaded teeth at one end of the adjusting rod. When the adjusting rod rotates, it can drive the two cylindrical components to move closer or further apart, thereby adjusting the distance between the two baffles. After the adjustment is completed, the adjusting rod is released and stops rotating. The baffle will also be limited to the current position, achieving the effect of automatic limiting after adjustment, saving the steps of adjusting the baffle distance.

[0015] 2. The center point of the two double cylinders only needs to be adjusted once on the adjusting rod. Since the two threaded teeth are opposite, when the adjusting rod rotates, it can control the movement of the two double cylinders at the same time. Thus, when the baffle spacing is adjusted each time, the center point can remain unchanged. This eliminates the need to readjust the center point in subsequent adjustments, further reducing the adjustment steps and avoiding the impact on the normal operation of the equipment caused by increased adjustment steps.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-4As shown, the flatbed die-cutting adjustment device includes a paperboard feeder 1, an adjustment mechanism 3 on the front side of the paperboard feeder 1, and baffle mechanisms 2 at both ends of the top of the paperboard feeder 1. Several roller grooves 11 are carved on the paperboard feeder 1, and paper feeding rollers 12 are installed inside each roller groove 11. A long slide groove 13 is carved at the top end of the roller groove 11 away from the adjustment mechanism 3. The baffle mechanism 2 includes a baffle 21, and a long slider 25 is fixed to the bottom of the baffle 21 near the long slide groove 13. The long sliders 25 are respectively inserted into the long slide groove 13 and slidably connected thereto. The baffle 21 is close to the adjustment mechanism 3. A side bracket 22 is fixed to the front of the position, and a double cylindrical part 23 is fixed to the bottom of the side bracket 22. The adjustment mechanism 3 includes two ear plates 31. An adjustment rod 32 is provided at the front end between the ear plates 31, and a fixing rod 33 is fixed at the rear end between the ear plates 31. One end of the adjustment rod 32 is rotatably connected to one of the ear plates 31, and the other end of the adjustment rod 32 is rotatably connected to the other ear plate 31 after passing through it. A handle 34 is fixed at one end of the adjustment rod 32 that passes through the ear plate 31. Threaded teeth 321 are provided on the outer walls of both ends of the adjustment rod 32 located between the two ear plates 31.

[0023] Specifically, one end of the double cylindrical member 23 of the two baffle mechanisms 2 is respectively sleeved on both ends of the adjusting rod 32 and threadedly connected to it with the unknown threaded teeth 321. The other end of the double cylindrical member 23 of the two baffle mechanisms 2 is respectively sleeved on both ends of the fixed rod 33 and slidably connected to it.

[0024] Specifically, the threads 321 at both ends of the adjusting rod 32 have opposite directions, so that when the adjusting rod 32 rotates, it can drive the two baffles 21 to move closer or further away at the same time.

[0025] Specifically, a support block 36 is provided between the adjusting rod 32 and the fixed rod 33. The fixed rod 33 is fixedly connected to the support block 36 after passing through it, and the adjusting rod 32 is rotatably connected to the support block 36 through a bearing to increase its support.

[0026] Specifically, the ear plate 31 is provided with bolts 35, and the ear plate 31 is detachably connected to the paper feed plate 1 by the bolts 35, which facilitates disassembly and assembly.

[0027] Specifically, the bottom of the baffle 21, which is located parallel to the paper feed roller 12, is chiseled with an arc-shaped bottom groove 24 to prevent the baffle 21 from touching the paper feed roller 12 when it moves. This also allows the baffle 21 to be closer to the top of the paper feed 1, so as to provide side protection for thinner paperboard.

[0028] Working principle: The double cylindrical parts 23 of the baffle mechanism 2 are slidably connected to the fixed rod 33 and threadedly connected to the threaded teeth 321 at one end of the adjusting rod 32. When the adjusting rod 32 rotates, it can drive the two double cylindrical parts 23 to move closer or further apart, thereby adjusting the distance between the two baffles 21. After the adjustment is completed, the adjusting rod 32 is released. After the adjusting rod 32 stops rotating, the baffles 21 will also be limited to the current position, achieving the effect of automatic limiting after adjustment. This saves the steps of adjusting the distance between the baffles 21. The center point of the two double cylindrical parts 23 only needs to be adjusted once on the adjusting rod 32. Since the two threaded teeth 321 are opposite, when the adjusting rod 32 rotates, it can control the movement of the two double cylindrical parts 23 at the same time. Therefore, when the distance between the baffles 21 is adjusted each time, the center point can remain unchanged. This eliminates the need to adjust the center point again in subsequent adjustments, further reducing the adjustment steps and avoiding the impact on the normal operation of the equipment caused by increased adjustment steps.
