Abstract
The utility model relates to an adjusting and locking device applied to thirty two output rollers of a printing machine. The adjusting and locking device comprises a threaded rod and a spring, the tail end of the threaded rod is connected in a threaded rod hole in a spring base on the side portion of a clamping plate rotating block, the head end of the threaded rod is installed on a roller body, the spring is arranged on the threaded rod in a sleeved mode, one end of the spring presses the stepped face of the inner wall of the roller body in an abutting-against mode, and the other end of the spring presses the spring base on the clamping plate rotating block in an abutting-against mode. The adjusting and locking device is characterized in that a threaded hole is formed in the head end of the threaded rod in the axis direction, a notch groove is formed in the head end of the threaded rod in the radial direction, a notch is formed in the position, corresponding to the notch groove, of the roller body, and positioning pieces are installed in the notch and the notch groove and fastened through a screw installed in the threaded hole. The adjusting and locking device is simple and ingenious in structure and capable of locking and fixing the threaded rod after the threaded rod is adjusted in place, so that the threaded rod does not loosen and disengage, and pressing force of the spring is kept unchanged.
Description
Technical field
The utility model relates to a kind of adjustment locking device being applied on printing press 32 output rollers, belongs to printing mechanism technical field.
Background technique
Along with the fast development of printing packaging industry, printing press is widely used in printing house.Printing press is generally comprised of mechanisms such as defeated paper, location, printing, collections, its working principle is as follows: the writings and image that first will print is made forme, be contained on printing press, then by artificial or printing press, China ink is coated in to the region that has writings and image on forme, be transferred to directly or indirectly again paper or other printing stocks (as textile, sheet metal, plastic cement, leather, timber glass and pottery etc.) upper, thereby copy the printedmatter identical with forme.
Thirty-two mo run-out roller is a kind of parallel paper foldling mechanism on printing press, for realizing second vertical folding of paper, first vertical folding of paper normally relies on octavo sheet folding mechanism to complete, through once indulging the paper of folding, there is the output overtime work of pushing output mechanism aside to clip rotation, when turning to thirty-twomo output and roll your holding paper position, paper folding passes to Thirty-two mo run-out roller and is driven rotates output.
The structure of existing Thirty-two mo run-out roller as shown in Figure 1, it is mainly comprised of roll body 1, backup plate 5, rotating shaft 2, clamping plate moving block 3, clamping plate 4, backup plate 5, screw rod 6 and spring 7, roll body 1 inside is cavity structure, rotating shaft 2 is arranged in roll body 1, clamping plate 4 are arranged in rotating shaft 2, and clamping plate moving block 3 is fixed in rotating shaft 2 by flat key, and the extension of the sidepiece of clamping plate moving block 3 is provided with spring abutment 3a, on spring abutment 3a, have screw hole, screw rod 6 tail ends are connected in screw hole; Described screw rod 6 head ends are arranged on roll body 1, and spring 7 is enclosed within on screw rod 6, and spring 7 tops, one end are pressed on roll body 1 inwall step surface, and the spring abutment 3a on clamping plate moving block 3 is pressed on spring 7 the other end tops, applies the thrust of a side direction to clamping plate moving block 3 and rotating shaft 2.But in actual use, because each component are in lasting motion state, screw rod 6 can often there will be loosening situation, cause spring 7 impacting forces to change, affect printing quality, in the time of seriously, very occur that screw rod 6 deviates from, to machine, cause damage.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of adjustment locking device being applied on printing press 32 output rollers is provided, its simple and ingenious structure, can regulate the laggard row that puts in place to be locked at screw rod, make screw rod can not become flexible, keep-spring impacting force be constant.
The technological scheme providing according to the utility model: adjust locking device, comprise screw rod and spring, screw rod tail end is connected in the screw hole on clamping plate moving block sidepiece spring abutment, screw rod head end is arranged on roll body, spring housing is on screw rod, top, spring one end is pressed on roll body inwall step surface, the spring abutment on clamping plate moving block is pressed on spring the other end top, it is characterized in that: the axis direction of described screw rod head end is provided with screw, screw rod head end be radially provided with a short slot, on described roll body, corresponding short slot position is provided with a notch, certain bit slice is housed in described notch and short slot, described location piece is by being contained in the screw fastening in screw.
As further improvement of the utility model, the axis direction of the misalignment screw rod head end of described short slot.
compared with prior art, advantage is the utility model:the utility model simple and ingenious structure, can regulate the laggard row that puts in place to be locked at screw rod, makes screw rod can not become flexible, and keep-spring impacting force is constant.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Figure 1: the adjustment locking device in embodiment is mainly by screw rod 6, spring 7, screw 8 and location piece 9 form, described screw rod 6 tail ends are connected in the screw hole on clamping plate moving block 3 sidepiece spring abutment 3a, screw rod 6 head ends are arranged on roll body 1, spring 7 is enclosed within on screw rod 6, spring 7 tops, one end are pressed on roll body 1 inwall step surface, the spring abutment 3a on clamping plate moving block 3 is pressed on spring 7 the other end tops, it is characterized in that: the axis direction of described screw rod 6 head ends is provided with screw, screw rod 6 head ends be radially provided with a short slot, on described roll body 1, corresponding short slot position is provided with a notch, certain bit slice 9 is housed in described notch and short slot, described location piece 9 is fastening by the screw 8 being contained in screw.
In the utility model, for guaranteeing the structural strength of screw rod 6, the axis direction of misalignment screw rod 6 head ends of described short slot.
During concrete application, first by adjusting screw rod 6 positions, adjust the impacting force of spring 7, after spring 7 impacting forces are adjusted, breach by location piece 9 from roll body 1 inserts in the short slot of screw rod 6 head ends, screw 8 is packed into the screw of screw rod 6 heads and tightens, thereby screw rod 6 is locked, and screw rod 6 can not become flexible, so just can spring 7 impacting forces constant.
