Technical Field

[0001] The utility model relates to a fixture, in particular to a book clamping device. Background Art

[0002] The description of this part only provides background information related to the disclosure of the utility model, and does not constitute prior art.

[0003] With the development of modern printing technology and the publishing industry, the production efficiency and quality of books have been continuously improved. During the production process of books, the clamping of books or papers is a key link to facilitate operations such as packaging books, and the stability of clamping directly affects the neatness and durability of the final books.

[0004] Generally, the existing clamping of papers used to make books or the books themselves is completed by clamping tools. However, books or papers are plate-like structures with a relatively large extended surface. The fixing stability of general clamping tools is not good, and manual intervention by operators is required, which affects the processing efficiency. At the same time, some other clamping tools have a high degree of automation, but they have complex structures, occupy a large space, and are costly, which is not conducive to flexible use in the assembly line. In particular, the driving mechanism of their clamping tools is arranged inside the device housing, which is not convenient for later maintenance.

[0005] Currently, there is no book clamping device that can solve the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a book clamping device that can drive a clamping mechanism to clamp books or papers by rotating a main shaft with two sections of opposite external threads, which has a compact structure, and the driving mechanism is arranged outside the housing, facilitating maintenance.

[0007] To achieve the above purpose, the utility model discloses a book clamping device as follows; the book clamping device includes:

[0012] Wherein, the first clamping plate and the second clamping plate are threadedly connected to the main shaft, and the external thread directions at the connection of the main shaft and the first clamping plate and the second clamping plate are opposite, so that when the rotor drives the main shaft to rotate, the first clamping plate and the second clamping plate approach or move away from each other along the axial direction.

[0013] Further, the first clamping plate and the second clamping plate extending out of the housing are arranged as a planar plate-like structure extending perpendicular to the axial direction and matching the size of a book or paper, and empty slots are arranged on the planar plate-like structure.

[0014] Further, the number of the empty slots is set to be multiple, so that the first clamping plate and the second clamping plate extending out of the housing form multiple strip-shaped pressing plates on both sides of the multiple empty slots.

[0015] Further, the lengths and widths of the multiple pressing plates are equal.

[0016] Further, the first clamping plate and the second clamping plate are mirror-symmetrically arranged perpendicular to the axial direction.

[0017] Further, a guiding mechanism is further included, the guiding mechanism is fixedly arranged in the housing, the guiding mechanism includes a guiding column, the guiding column extends parallel to the axial direction, and the guiding column passes through the first clamping plate and the second clamping plate arranged in the housing.

[0021] 1. For the book clamping device of the present utility model, by driving the main shaft with two sections of opposite external threads to rotate by the driving mechanism, the first clamping plate and the second clamping plate in the clamping mechanism can flexibly move relatively or away from each other along the axial direction, the structure is compact, and through the mature motor drive, the clamping effect on the book or paper is stable. At the same time, most of the structures in the driving mechanism of the book clamping device of the present utility model are arranged on one side outside the housing, which is convenient for the operator to quickly maintain and service the device later.

[0022] 2. The first clamping plate and the second clamping plate of the book clamping device of the present utility model are arranged as a planar patchy structure and include a plurality of empty slots, so that the pressing plates with certain elasticity formed on both sides of the empty slots can clamp books or papers more stably, and are lighter in weight, and the activities of the first clamping plate and the second clamping plate are more stable.

The following describes the implementation manners according to the overall structure of the present utility model.

[0029] Please refer to Figure 1 , which is a book clamping device of this embodiment; wherein the book clamping device includes:

[0030] A housing 1;

[0031] A main shaft 2, the main shaft 2 extends along the axial direction, the main shaft 2 has a first end and a second end arranged oppositely, the first end of the main shaft 2 is rotatably abutted against the inner wall of the housing 1, and the second end of the main shaft 2 passes through the housing 2 so that at least a part of the main shaft 2 extends out of the housing 1;

[0032] A driving mechanism 3, the driving mechanism 3 includes a transmission wheel 31, a belt 32 and a rotor 33, the transmission wheel 31 is connected to the second end of the main shaft 2, and the belt 32 is sleeved on the output shaft of the transmission wheel 31 and the rotor 33 respectively;

[0033] A clamping mechanism 4, the clamping mechanism 4 includes a first clamping plate 41 and a second clamping plate 42 arranged oppositely along the axial direction, the main shaft 2 passes through the first clamping plate 41 and the second clamping plate 42 respectively, and at least a part of the first clamping plate 41 and the second clamping plate 42 extends out of the housing 1;

[0034] Wherein, the first clamping plate 41 and the second clamping plate 42 are threadedly connected to the main shaft 2, and the external thread directions at the connection of the main shaft 2 and the first clamping plate 41 and the second clamping plate 42 are opposite, so that when the rotor 33 drives the main shaft 2 to rotate, the first clamping plate 41 and the second clamping plate 42 approach or move away from each other along the axial direction.

[0035] For the above structure, during installation, first prepare the housing 1 with a preset size. The housing 1 has two top walls and side walls, upper and lower. After opening one of the side walls of the housing 1, place the rotor 33 of the driving mechanism 3 in the housing 1 so that the main body of the rotor 33 is disposed inside the housing 1, and one side surface of the main body of the rotor 33 is fixed to the top surface of the housing 1 by a fastener, and the output shaft of the rotor 33 penetrates through the top surface of the housing 1. At the same time, provide a main shaft 2 with an axial dimension matching that of the housing 1, and threadedly mount the first clamping plate 41 and the second clamping plate 42 of the clamping mechanism 4 on the main shaft 2 in the corresponding directions. Then, place a part of the main shaft 2, the first clamping plate 41 and the second clamping plate 42 inside the housing 1. Among them, the first end of the main shaft 2 is rotatably mounted at a point on the bottom of the housing 1, the second end of the main shaft 2 penetrates and extends outside the housing 1, and a transmission wheel 31 is sleeved on the second end of the main shaft 2. Adjust the transmission wheel 31 to be axially parallel to the end gear of the output shaft of the rotor 33, and sleeve a belt 32 for drivingly connecting the transmission wheel 31 and the rotor 33. Finally, install the remaining part of the housing 1 so that the transmission wheel 31, the belt 32 and a part of the output shaft of the rotor 33 in the driving mechanism 3 are disposed outside the housing 1, a part of the first clamping plate 41 and the second clamping plate 42, and the remaining part of the first clamping plate 41 and the second clamping plate 42 are disposed outside the housing. The book clamping device of this embodiment is installed and completed.

[0036] With the above structure, during use, the operator only needs to place the paper or book at a preset position between the first clamping plate 41 and the second clamping plate 42, and then drive the rotor 33 of the driving mechanism 3 to start. The output shaft of the rotor 33 drives the gear to rotate, the gear drives the belt 32 to roll, and the belt 32 drives the transmission wheel 31 on the other side to rotate. Since the transmission wheel 31 is fixedly connected to the main shaft 2, the main shaft 2 rotates around its axis. At this time, since the main shaft 2 is threadedly connected to the first clamping plate 41 and the second clamping plate 42, and the external threads of the main shaft at the connection between the first clamping plate 41 and the main shaft 2 and the external threads of the main shaft at the connection between the second clamping plate 42 and the main shaft 2 are in opposite axial directions. That is to say, when the rotor 33 of the driving mechanism 3 rotates in the positive direction, due to the middle position of the first clamping plate 41 and the second clamping plate 42 being limited by the housing 1, the threaded holes of the first clamping plate 41 and the second clamping plate 42 mounted on the main shaft 2 rotate relative to the threads of the main shaft 2, and the first clamping plate 41 and the second clamping plate 42 approach each other until the book or paper to be clamped between the first clamping plate 41 and the second clamping plate 42 is completely clamped. The operator stops the rotor 33 to realize the positioning of the book or paper, and can continue the next processing operation on the book or paper. After the processing of the book or paper is completed, the operator restarts the rotor 33 to make the rotor 33 rotate in the reverse direction, and similarly drives the first clamping plate 41 and the second clamping plate 42 to separate from each other, so that the operator can take out the processed paper or book from between the first clamping plate 41 and the second clamping plate 42.

[0037] During the above use process, only by rotating the main shaft 2 inside the housing 1 can the first clamping plate 41 and the second clamping plate 42 of the clamping mechanism 4 be driven to move up and down to clamp the object to be clamped. Moreover, the square rotor 33 body in the driving mechanism 3 can be arranged inside the housing 1, making the volume of the whole device compact and occupying less space. The rest of the parts are arranged outside the top of the housing 1, making the parts that often need maintenance more accessible.

[0038] Furthermore, please refer to Figure 1 and Figure 2 , the first clamping plate 41 and the second clamping plate 42 extending out of the housing 1 are set as flat plate-like structures extending along a plane perpendicular to the axial direction and matching the size of a book or paper. And empty slots 43 are arranged on the flat plate-like structure. At the same time, the number of the empty slots 43 is set to be multiple, so that the first clamping plate 41 and the second clamping plate 42 extending out of the housing 1 form multiple strip-shaped pressing plates 44 on both sides of the multiple empty slots 43, and the lengths and widths of the multiple pressing plates 44 are equal. Specifically, in this embodiment, the first clamping plate 41 and the second clamping plate 42 respectively have two empty slots 43 and a total of three pressing plates 44 located on both sides of the two empty slots 43. Through the above structure, the first clamping plate 41 and the second clamping plate 42 are set as plate-like structures matching the object to be clamped, and can fix thinner books and other structures more stably. At the same time, since a book or paper is composed of multiple thin paper pages stacked together, the paper page stack itself has a certain elasticity. At the same time, the multiple strip-shaped pressing plates 44 are more elastic than a complete surface without the empty slots 43, so that when the pressing plates 44 are pressed on the surface of the book or paper, both the pressing plates 44 and the book or paper itself undergo slight elastic deformation, so that the contact area between the pressing plates 44 of the first clamping plate 41 and the second clamping plate 42 and the book or paper increases, and it is pressed more tightly, avoiding the detachment of the book or paper.

[0039] Furthermore, the first clamping plate 41 and the second clamping plate 42 are mirror-symmetrically arranged perpendicular to the axial direction. That is to say, the first clamping plate 41 and the second clamping plate 42 are oppositely arranged, and the axial projection planes of the first clamping plate 41 and the second clamping plate 42 cover each other. Substantially, the first clamping plate 41 and the second clamping plate 42 are entities with the same structure but different installation positions, which is convenient for mutual replacement and reduces the cost of the first clamping plate 41 and the second clamping plate 42 at the same time.

[0040] Furthermore, it further includes a guiding mechanism 5 which is fixedly arranged inside the housing 1. The guiding mechanism 5 includes a guiding column 51 that extends parallel to the axial direction and passes through the first clamping plate 41 and the second clamping plate 42 arranged inside the housing 1. Among them, the guiding mechanism 5 further includes a fixing plate 52 which is arranged at one end of the guiding column 51 along the axial direction towards the inner wall of the housing 1. At the same time, the number of guiding columns 51 is multiple, and the number of guiding columns 51 on both sides of the main shaft 2 perpendicular to the axial direction is equal. Through the above structure, the clearance space inside the housing 1 can be fully utilized, and the guiding mechanism 5 is used to realize the stability of the movement when the first clamping plate 41 and the second clamping plate 42 move along the axial direction, avoiding the problems of skewed clamping of books or papers caused by the offset of the first clamping plate 41 and the second clamping plate 42 and affecting the processing. Among them, the number of guiding columns 51 is set to four. The four guiding columns 51 are arranged in two groups, one in front and one behind, along the extending direction of the first clamping plate 41 and the second clamping plate 42, and are respectively arranged on both sides of the main shaft 2, so that the parts of the first clamping plate 41 and the second clamping plate 42 inside the housing 1 move with better balance. The fixing plates 52 are set to two. The upper and lower fixing plates 52 are respectively arranged near the top surface and the bottom surface of the housing 1. One end of the two guiding columns 51 on the bottom surface is installed on one fixing plate 52 at the bottom side, and one end of the two guiding columns 51 on the top surface is installed on one fixing plate 52 at the top, making the two guiding columns 51 at the corresponding positions more stably fixed to each other and the guiding of the guiding columns 51 not easily deviated.

The embodiments of applying these modified or deformed data acquisition, processing, output, judgment methods, etc. still fall within the scope of the optional implementation schemes of this application.

[0042] Although this application is depicted through embodiments, those of ordinary skill in the art know that this application has many deformations and changes without departing from the spirit of this application, and it is hoped that the appended embodiments include these deformations and changes without departing from this application.
