Description

Technical Field

[0001] The utility model relates to the technical field of printing grid frames, in particular to a novel printing grid frame. Background Art

[0002] A printing press is a machine for printing text and images. Modern printing presses are generally composed of mechanisms such as plate loading, inking, pressing, and paper feeding. Its working principle is: first, the text and image to be printed are made into a printing plate, which is then installed on the printing press. Then, ink is applied to the places where the text and image are on the printing plate by humans or the printing press, and then directly or indirectly transferred to paper or other substrates such as textiles, metal plates, plastics, leather, wood boards, glass, and ceramics, thereby replicating printed products that are identical to the printing plate.

[0003] The printing grid of the existing printing machine is generally composed of a crossbeam and a connecting column. However, after the height of the printing grid is adjusted during use, the support is not stable enough and is easy to loosen. Generally, the printing plate is moved downward to squeeze the paper on the printing grid for printing, but there is a downward pressing force that can easily damage the printing grid, and different heights of the grid need to be set for papers of different thicknesses to meet the pressure requirements. Otherwise, it is easy to produce false printing or blurred printing. The paper thickness required by each customer is different, and it is very troublesome to fine-tune the height.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model. The hand crank handle body is not drawn in the drawings of the present application, only the driving rod is reflected. The hand crank handle body is a conventional prior art and will not be described in detail in this application. The technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] Embodiment 1

[0027] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 And attached Figure 8 As shown, a novel printing grid frame includes a housing 1 and a printing grid frame 13 located on the upper side of the housing 1.

[0028] A support plate 17 that can move up and down is provided in the shell 1, a fine-tuning component 3 is provided between the support plate 17 and the printing grid 13, a gear column 4 is provided below the support plate 17, a support column 6 and a driving rod 9 are rotatably provided on the shell 1, a gear 1 5 and a gear 2 7 are provided on the support column 6, the gear 1 5 is meshed with the gear column 4, the gear 2 7 is meshed with the gear 3 8 on the driving rod 9, a ratchet 10 is provided on the driving rod 9, a synchronous belt 11 is connected between the driving rods 9, and the ratchet 14 cooperates with the ratchet 10 when in a relaxed state.

[0029] Through the above structure, a hand crank is installed on one of the driving rods 9, and the hand crank is cranked to rotate one of the driving rods 9, and the other driving rod 9 rotates under the action of the synchronous belt 11, the ratchet 10 on the driving rod 9 rotates with the gear three 8, the gear two 7 matched with the gear three 8 rotates, and the support column 6 in the middle of the gear two 7 rotates, driving the gear one 5 on the support column 6 to rotate, thereby controlling the rise and fall of the tooth column 4 matched with the gear one 5. Due to the existence of the ratchet 14, when it is in a relaxed state, the tooth column 4 can only rise and cannot be reversed, so that the height of the printing grid frame 13 is fixed. After the printing height is determined, it is only necessary to give a specific force to the printing grid frame 13 to make the ratchet 14 leave the ratchet 10. Due to the weight of the grid frame and the support plate, the gear group can be driven to reverse and the tooth column 4 can descend.

[0030] Embodiment 2

[0031] Based on the first embodiment, combined with the attached Figure 4 To Attachment Figure 7 As shown, the fine-tuning assembly 3 includes a spring 12 for connecting the printing grid 13 and the support plate 17, the housing 1 is provided with a fixed column 15 and a fixed column 20, the fixed column 15 is slidably connected with a pawl 14, a spring 26 is connected between the pawl 14 and the fixed column 15, the upper side of the pawl 14 is a push rod 2 arranged on the printing grid 13, the fixed column 20 is slidably connected with a pawl 2 19, one side of the pawl 2 19 is provided with a spring 2 16, and the upper side of the pawl 2 19 is provided with a push rod 2 18, the push rod 18 is connected to the printing grid 13 through the spring 3 21, the upper ends of the pawl 14 and the pawl 2 19 are sloped, the pawl 14 cooperates with the ratchet 10 when in a relaxed state, the pawl 2 19 does not contact the ratchet 10 when in a relaxed state, the push rod 2 contacts the pawl 14 when relaxed, and the push rod 2 18 does not contact the pawl 2 19 when in a relaxed state, a groove is provided on the support plate 17, the push rod 1 2 and the push rod 2 18 slide in the groove, and the bottom of the push rod 1 2 and the push rod 2 18 is T-shaped.

[0032] Through the above structure, after the initial height of the printing grid 13 is determined, the paper is placed on the printing grid 13. Under the action of gravity, the springs 12 around the support plate 17 contract, the printing grid 13 descends, the push rod 2 descends, contacts the top of the pawl 14, and pushes the pawl 14 along the slope to slide on the fixed column 15. When the gravity of the paper reaches a certain fixed value, the pawl 14 is completely pushed away from the pawl 14. Under the action of gravity, the gear set reverses and the height decreases. At the same time, the spring 3 21 connected to the printing grid 13 is subjected to gravity, and the push rod 2 18 pushes the pawl 2 19 to contact the ratchet 10. The movement stops and the height stops falling. When the paper is taken down, the printing grid 13 is no longer subject to gravity, the spring 12 stretches, the pawl 14 is no longer under pressure, and the spring 2 16 on one side of the pawl 14 stretches to push the pawl 14 to contact the ratchet 10. After the pawl 2 19 is no longer under pressure, the spring 2 16 on one side of the pawl 2 19 contracts to pull the pawl 2 19 away from the ratchet 10. Since the spring 3 21 is more sensitive than the spring 12 and the push rod 2 18 does not contact the pawl 2 19 in the relaxed state, the pawl 2 19 returns to its position before the pawl 14. After the pawl 14 returns to its position, the hand crank handle stops rotating and this position is fixed.

[0033] The specific method of use is as follows: when in use, the height of the printing grid frame 13 is initially adjusted to a suitable height. Since the ratchet 10 and the pawl 14 cooperate, the adjusted frame is stable and does not rotate. When paper is placed on the printing grid frame 13, due to the different weights of the paper, the spring 12 and the spring 3 21 will be subjected to forces exceeding a certain range, squeezing the pawl 14 and the pawl 2 19 to leave and contact the ratchet 10 respectively. Since the actions of the pawl 14 and the pawl 2 19 are in sequence, the height can be automatically reduced within a certain range. After the pawl 2 19 contacts the ratchet 10, the height is fixed. When in a relaxed state, the spring 2 16 drives the pawl 14 and the pawl 2 19 to return to their positions. After the printing grid frame 13 is returned to its position by shaking the hand crank handle, it is fixed by the pawl 14.
