With reference to fig. 1 to 3, the present embodiment provides a printing apparatus including: the printing device comprises a machine body 1, and a printing rubber roller 2, a printing component 3 and a paper feeding group 4 which are arranged in the machine body 1. Printing assembly 3 and printing rubber roll 2 mutual opposition form the printing space that can hold recording paper A, and the both ends of printing rubber roll 2 are the free end, and dispose the cooperation structure that can be connected with the power supply on at least one free end. The paper feeding group 4 has a paper feeding channel, and the driving force for the recording paper a to transport the paper along the paper feeding channel is provided by one of the paper feeding group 4 and the printing roller 2.
In the above embodiment, the paper feeding group 4 and the printing roller 2 provided in the paper feeding path are used to alternatively feed the recording paper a. Wherein, when the printing work of the condition such as need high accuracy, printing position requirement are very accurate, select to send paper group 4 to provide drive power to recording paper A, print 2 both ends of rubber roll and be in free state this moment, only make when the paper feed print the rubber roll 2 and follow recording paper A and rotate, guarantee to print the more accurate printing in printing space that forms between rubber roll 2 and the printing assembly 3. When general paper feeding printing work is needed, the paper feeding driving is directly carried out only by the printing rubber roller 2, the printing requirement can be met, and the paper feeding printing is more efficient.
It should be noted that, compared with the driving of the printing rubber roller 2 to the recording paper a, the difference of the paper feeding group 4 is that the paper feeding is carried out on one side of the non-printing space, so that the controllability is higher, the driving regulation and control are more facilitated, and the operability is good. This printing apparatus can be compatible the printing of multiple mode, satisfies the printing demand in most consumptive material, and has richened printing apparatus's use scene, and it can be nimble adaptation in the various printing types of present stage, does benefit to popularization, popularization.
In one embodiment, the paper feeding set 4 comprises a paper pressing roller 5 and a paper feeding roller 6, and the paper pressing roller 5 and the paper feeding roller 6 are arranged on two sides of the machine body 1 in a matching way to form the paper feeding channel. And both ends of the platen roller 5 are free ends. Wherein, a printing space is formed between the printing component 3 and the printing rubber roller 2, and a paper feeding channel is formed between the paper pressing roller 5 and the paper feeding roller 6 for paper feeding transmission. And when not being driven by the power source, both ends of the printing rubber roller 2 are always in a free state, at the moment, the paper feeding roller 6 of the paper feeding group 4 provides driving force, and the printing rubber roller 2 only rotates along with the driving of the recording paper A. When the printing rubber roller 2 is driven by power to convey paper, and two ends of the paper pressing roller 5 are always in a free state, so that the recording paper A can be fed into the paper feeding channel. It should be noted that the two rollers are in a state of being free at both ends in the machine body 1, and specifically, both ends of the roller may be configured in rolling bearing seats (not shown).
Preferably, the paper feeding set 4 is located at the downstream side of the printing space, and the platen roller 5 and the paper feeding roller 6 are opposed to each other with an elastic pressing force. The printing assembly 3 and the printing rubber roller 2 which are opposite to each other, and the paper pressing roller 5 and the paper feeding roller 6 which are opposite to each other are sequentially arranged along the direction of a paper feeding path. And the paper pressing roller 5 is elastically arranged in the machine body 1 and is arranged at an interval with the paper feeding roller 6, so that the paper feeding channel can be adaptive to the thickness of the recording paper A, and the paper pressing roller 5 can be abutted by the recording paper A to be elastically lifted along the vertical direction. It is to be explained that the upstream side and the downstream side are defined based on the conveying direction of the printing paper feed.
Wherein, in particular, the outer periphery of the paper feeding roller 6 is provided with a raised spine structure 7, and the raised spine structure 7 is arranged on the paper feeding path, so that the recording paper A is tightly clamped in the paper feeding channel. In this embodiment, the protruding spine structures 7 are preferably integrally formed at two ends of the periphery of the paper feeding roller 6, and the protruding spine structures 7 at two sides are disposed at intervals, and the length range formed by the protruding spine structures 7 at least satisfies that the recording paper a can fall into the area of the protruding spine structures 7 along the width direction, so as to improve the friction stress of the recording paper a in the paper feeding channel, and further achieve the purpose of stable and accurate paper feeding and conveying. It is apparent that the arrangement of the spur structure 7 does not substantially damage the recording paper a.
In the above implementation, the printing apparatus further includes a driving assembly 8 disposed within the body 1. The driving assembly 8 is configured to be capable of switching its power source between the paper feeding set 4 and the printing blanket 2 in an operable manner, so that the driving force for conveying the recording paper a is alternatively selected to be provided by the paper feeding set 4 or the printing blanket 2. It should be noted that, the switching manner of the power source provided by the driving assembly 8 can be implemented by, but not limited to, a reversing group (not shown) in the form of transmission reversing. Specifically, the driving assembly 8 transmits the power source to the printing roller 2 side under the transmission of one of the switching states of the reversing group, or transmits the power source to the paper feeding group 4 side under the transmission of the other switching state of the reversing group. The reversing group is preferably a gear reversing structure.
In other embodiments, the driving assembly 8 may be directly moved to be in transmission connection with the printing roller 2 or to be in transmission connection with the paper feeding roller 6, so that the driving assembly 8 moves between two transmission positions, thereby realizing power source switching.
It should be noted that, in the above-mentioned embodiments, the driving assembly 8 selects one of the driving assemblies to transmit the power source, and only one of the printing roller 2 and the paper feeding roller 6 is driven to rotate, so that one of the paper feeding roller 6 and the printing roller 2 transmits the recording paper a unilaterally.
Referring to fig. 4 to fig. 7, it is different from the above-mentioned driving assembly 8 that a power source is used to transmit the driving force in a switching manner. In another embodiment, the paper feeding set 4 and the printing roller 2 are controlled by different power sources. Specifically, the paper feeding group 4 is connected with a power source (provided by a driving component 8) of the machine body 1, and the printing rubber roller 2 is connected with a power source B outside the machine body 1 through a matching structure at the end part of the printing rubber roller. The external power source B is detachably coupled to the machine body 1. However, only one of the self-contained power source and the external power source B performs the driving operation. Therefore, the paper feeding roller 6 and the printing rubber roller 2 are driven independently by different power sources in such a way, the defect of single power source driving is overcome, a complex reversing and transmission structure is eliminated, and the driving mode is simpler and more efficient. In particular, the printing device can be externally provided with a detachable power source device, and the efficacy of the device is more obvious.
Furthermore, the matching structure enables the external power source B and the printing rubber roller 2 to be linked in a clamping and nesting mode. The matching structure comprises a buckling part 9 which is constructed at one end part of the printing rubber roller 2 and can be in concave-convex fit with the output shaft of the power source B, and a profiling concave part (not shown) which is constructed at the output end of the external power source B and can be clamped and nested with the buckling part 9. The snap-fit portion 9 can be detachably coupled to the output shaft to be directly drivingly connected after assembly. Thereby, print 2 tip structures of rubber roll for can with the buckle portion 9 of the unsmooth adaptation of output shaft looks of power supply, print 2 other ends structures of rubber roll for the free end, its free end is not connected the effect with external drive spare to can keep printing the steady rotation of rubber roll 2 at the printing line. And, the buckling part 9 can be detachably connected with the output shaft so as to be directly connected with the output shaft in a transmission way during assembly. The output shaft is combined with the buckling part 9 to enable the printing rubber roller 2 to directly rotate after receiving power, and the recording paper A is conveyed. The assembly and disassembly are more convenient, and the transmission precision is greatly improved.
More specifically, the snap-fit portion 9 has a notch and a cross section of a substantially D-shape (as shown in fig. 5), and the output shaft of the power source B is configured to be able to engage with the profiling recess of the snap-fit portion 9. The D-shaped bayonet part can be completely embedded and clamped with the profiling concave part, so that the printing rubber roller 2 is synchronously driven to rotate along the rotation direction of the output shaft, one end part of the printing rubber roller 2 is in driven connection in a clamping and nesting mode, the other end part is in free follow-up, the printing rubber roller 2 is only connected with a power source, and the printing rubber roller is not interfered during rotation.
It should be noted that in other embodiments, the locking portion 9 may also be configured to have a cross-section in a straight shape (as shown in fig. 4), a cross shape, or the like, and the profiling recess is always configured to be fittingly nested and engaged with the locking portion 9.
With reference to fig. 6, 7 and 8, the present embodiment further provides a printing test system, which includes a machine body 1, and a printing roller 2, a printing assembly 3 and a paper feeding assembly 4 disposed in the machine body 1. Printing assembly 3 and printing rubber roll 2 mutual opposition form the printing space that can hold recording paper A, and the both ends of printing rubber roll 2 are the free end, and dispose the cooperation structure that can be connected with the power supply on at least one free end. Wherein a pressure regulating assembly 10 and at least one tension assembly (not shown) are also included.

The tension assembly is arranged at one end of the recording paper A far away from the printing space. The power source is a power source B arranged outside the machine body 1, and the power source is connected with the printing rubber roller 2 through a matching structure so as to drive the printing rubber roller 2 to rotate.
In the above embodiment, the printing rubber roller 2 forming the printing space with the printing component 3 drives the recording paper a to be transmitted along the paper feeding path under the driving of the external power source B, and the power source B is directly connected with the printing rubber roller 2 in a transmission manner, so that the paper feeding transmission of the recording paper a is realized, the problems of large transmission error and the like caused by an unnecessary transmission structure are avoided, and the printing press of the recording paper a is effectively and intuitively fed back. And, both ends of the printing blanket 2 are constructed as free ends, and at least one free end is provided with a fitting structure connected with an external power source B, so that only the printing blanket 2 is coupled with the power source through the follower of one end portion thereof at the driving source and the free follow-up of the other end portion, so that the transmission is more stable and is not interfered by the outside.
