Description

Technical Field

[0001] The present invention relates to the field of devices related to printing, and specifically to an automatic paper clamp suitable for batch clamping after printing. Background Art

[0002] After people daily use a printer to complete the printing work, the output paper is necessarily loose. In order to facilitate the circulation and preservation of the printed paper, at least two clips are required to clamp these papers.

[0003] In order to facilitate the clamping of papers and documents, the Chinese utility model patent with the application number 89219673.4 proposed an automatic folder. The device includes a housing main body, a clip pushing device and an opening component. The front end of the housing main body is a document slot, and the rear end is an opening for loading clips. There are guide rails with a wider bottom and a narrower top on the inner side of the housing. Between the guide rails and the document slot are two parallel herringbone spring sheets. The distance between the two herringbone spring sheets is greater than the main body width of the clip but less than the side edge width of the clip. The clip is pushed in the guide rail by the clip pushing device and opened by the opening component, and clamps the document placed in the document slot.

[0004] Since most of the currently used clips are long clip handles and flip-type clips, the above technology has been difficult to meet the current clamping requirements. Summary of the Invention

[0005] Now, in order to meet the above requirements for paper clamping, the present invention proposes an automatic paper clamp suitable for batch clamping after printing.

[0006] The technical problems to be solved by the present invention are realized by adopting the following technical solutions:

[0007] An automatic paper clamp suitable for batch clamping after printing, including a base table and a high pedestal installed in the middle of the upper part of the base table. A rectangular positioning groove is provided on the high pedestal; there are 4 support legs at the bottom of the high pedestal, and the 4 support legs are located at relatively central positions at the bottom of the high pedestal. The positioning groove penetrates to the rear end of the high pedestal. A clamping assembly is installed on the high pedestal; moving devices and clamping auxiliary devices are installed on both the left and right sides of the base table. Each moving device includes a lead screw; each clamping auxiliary device includes a disc seat threadedly engaged with the lead screw; two clip opening and closing components are also installed on each disc seat. The positioning groove is used to place the printed paper. The clamping assembly is used to press the paper in the positioning groove for easy clamping. The moving device is used to move the clip, and the clamping auxiliary device is used to fix and control the clip to clamp the paper. The clip opening and closing component is used to connect the clip handle.

[0008] Further, the clamping assembly consists of a suspension seat installed on the high pedestal, a No. I hydraulic cylinder installed on the suspension seat, and a pressing plate connected to the No. I hydraulic cylinder; the suspension seat is provided with side grooves for slidably installing the pressing plate. That is, under the drive of the No. I hydraulic cylinder, the pressing plate presses down to realize clamping the printing paper.

[0009] Further, each moving device further includes a rear frame installed on the high pedestal and a motor and a guide rod installed on the rear frame; the motor is correspondingly connected to the lead screw; the guide rod is slidably matched with the disc seat. That is, the two disc seats can move horizontally under the action of the lead screw nut drive.

[0010] Further, each disc seat is provided with two No. I arc grooves and an opening groove. The opening groove is to avoid interference between the disc seat and the upper part of the high pedestal when the disc seat moves. The No. I arc groove is used to control the movement track of the clamping handle of the clip.

[0011] Further, each clamping auxiliary device includes a side vertical plate installed on the disc seat, two transverse rods that slide correspondingly and are hinged with the No. I arc grooves, and two front blocks correspondingly connected to the transverse rods; an implementation component is installed on each front block. The implementation component is used to fix the clamping handle of the clip. The side vertical plate is used to install and position the clip.

[0012] The implementation component includes a guide rail installed on the front block and two clamping blocks slidably installed on the guide rail; each clamping block is provided with a No. II arc groove. The two clamping blocks can be used to fix the clamping handle of the clip, and the No. II arc groove is to better realize the fixation of the clamping handle.

[0013] Further, the implementation component further includes a three-axis cylinder installed on the front block and a transfer block connected to the three-axis cylinder. Each transfer block is provided with two symmetrically arranged inclined grooves up and down; a convex rod slidably matched with the inclined groove is welded on each clamping block. The three-axis cylinder pushes and pulls the transfer block, which can make the two convex rods slide relatively or move towards each other, so as to control the clamping or releasing of the clamping handle of the clip.

[0014] Further, the two inclined grooves on each transfer block are arranged symmetrically up and down in a mirror image. This structure is a necessary design to ensure the relative sliding or moving towards each other of the two convex rods.

[0015] Further, each clip opening and closing component is composed of a No. II hydraulic cylinder installed on the disc seat, a transverse guide rod installed on the disc seat, and a moving block connected to the No. II hydraulic cylinder. After the clamping handle of the clip is fixed, the moving block can be pulled back by the No. II hydraulic cylinder, that is, the clamping handle of the clip is driven backward, and the clip opening is expanded to facilitate the subsequent need for clamping the paper.

[0016] Furthermore, each movable block is provided with a vertical groove that slidably and hingedly cooperates with the corresponding horizontal rod. This structure is a necessary condition for the clip handle of the clip to be controllably rotated and moved backward.

[0017] The beneficial effects of the present invention are as follows:

[0018] The present invention can automatically install two clips, expand the clip mouth, and control them to automatically clamp paper. Moreover, most of the entire clamping process relies on equipment for automatic clamping, which is convenient to operate and suitable for large-scale clamping use. BRIEF DESCRIPTION OF THE DRAWINGS

A rectangular positioning groove 2a is provided on the high platform base 2; four support legs are provided at the bottom of the high platform base 2, and the four support legs are located at relatively central positions at the bottom of the high platform base 2. The positioning groove 2a penetrates to the rear end of the high platform base 2. A clamping assembly is installed on the high platform base 2; moving devices and clamping auxiliary devices are installed on both the left and right sides of the base table 1. Each moving device includes a lead screw 3; each clamping auxiliary device includes a disc seat 4 threadedly engaged with the lead screw 3; two clip opening and closing assemblies are also installed on each disc seat 4. The positioning groove 2a is used to place the printed paper. The clamping assembly is used to press the paper in the positioning groove 2a for easy clamping. The moving device is used to move the clip, and the clamping auxiliary device is used to fix and control the clip to hold the paper. The clip opening and closing assembly is used to connect the handle of the clip.

[0029] As Figure 2 shown in the figure, the clamping assembly consists of a hanging seat 5 installed on the high platform base 2, a No. I hydraulic cylinder 6 installed on the hanging seat 5, and a pressure plate 7 connected to the No. I hydraulic cylinder 6; a side groove 5a for slidably installing the pressure plate 7 is provided on the hanging seat 5. That is, under the drive of the No. I hydraulic cylinder 6, the pressure plate 7 presses down to clamp the printed paper.

[0030] As Figure 1 shown in the figure, each moving device further includes a rear bracket 19 installed on the high platform base 2, a motor 8 and a guide rod 9 installed on the rear bracket 19; the motor 8 is correspondingly connected to the lead screw 3; the guide rod 9 is slidably engaged with the disc seat 4. That is, the two disc seats 4 can move horizontally under the action of lead screw nut transmission.

[0031] As Figure 1 and Figure 3 shown in the figure, two No. I arc grooves 4a and an opening groove 4b are provided on each disc seat 4. The opening groove 4b is to avoid interference between the disc seat 4 and the upper part of the high platform base 2 during movement. The No. I arc groove 4a is used to control the movement track of the handle of the clip.

[0032] As Figure 3 and Figure 4 shown in the figure, each clamping auxiliary device includes a side vertical plate 11 installed on the disc seat 4, two transverse rods 10 sliding and hinged corresponding to the No. I arc grooves 4a, and two front blocks 12 correspondingly connected to the transverse rods 10; an implementation assembly is installed on each front block 12. The implementation assembly is used to fix the handle of the clip. The side vertical plate 11 is used to install and position the clip.

[0033] As Figure 4As shown in the figure, the implementation components include a guide rail 13 installed on the front block 12 and two clamping blocks 14 slidably installed on the guide rail 13; each clamping block 14 is provided with a No. II arc groove 14a. The two clamping blocks 14 can be used to fix the handle of the clip, and the No. II arc groove 14a is for better fixing of the handle.

[0034] As Figure 4 shown in the figure, the implementation components further include a three-axis cylinder 15 installed on the front block 12 and a transfer block 16 connected to the three-axis cylinder 15. Each transfer block 16 is provided with two symmetrically arranged inclined grooves 16a up and down; each clamping block 14 is welded with a convex rod 14b that slidably cooperates with the corresponding inclined groove 16a. The three-axis cylinder 15 pushes and pulls the transfer block 16, which can make the two convex rods 14b slide relative to each other or slide towards each other, so as to control the clamping or releasing of the handle of the clip.

[0035] The two inclined grooves 16a on each transfer block 16 are arranged symmetrically up and down in a mirror image. This structure is a necessary design to ensure the relative sliding or opposite sliding of the two convex rods 14b.

[0036] As Figure 3 shown in the figure, each clip opening and closing component is composed of a No. II hydraulic cylinder 17 installed on the disc seat 4, a transverse guide rod 18 installed on the disc seat 4, and a moving block 20 connected to the No. II hydraulic cylinder 17. After the handle of the clip is fixed, the moving block 20 can be pulled back by the No. II hydraulic cylinder 17, that is, the handle of the clip is driven backward, and the clip opening is expanded to facilitate the subsequent clamping of paper.

[0037] As Figure 3 shown in the figure, each moving block 20 is provided with a vertical groove 20a that slidably and hingedly cooperates with the corresponding transverse rod 10. This structure is a necessary condition for the handle of the clip to be controlled to rotate and move backward.

[0038] The specific usage steps of the present invention are as follows:

[0039] Step 1: Prepare the paper.

[0040] Align the printed papers and place them on the positioning groove 2a together, so that a part of the rear side of the paper is exposed outside the positioning groove 2a, and then the No. I hydraulic cylinder 6 drives the pressing plate 7 to press the paper.

[0041] Step 2: Install the two clips on the disc seat 4 respectively.

[0042] As Figure 5The clamping mouths of the shown clips are double-sidedly abutted through the side vertical plates 11, so that the hinge points of the two clamping handles of the clip are respectively concentric with the two No. I arc grooves 4a. Then, by pulling the transfer block 16 with the three-axis cylinder 15, the two clamping blocks 14 can be closed, so as to clamp and fix the front ends of the two clamping handles of each clip. The fixed state is as shown in Figure 6 shown

[0043] Step 3: Expand the clamping mouth

[0044] Pull the variable block 20 backward through the No. II hydraulic cylinder 17, that is, rotate the clamping handle of the clip backward. After rotating to a certain extent, the clamping mouth of the clip will be expanded

[0045] Step 4: Move and clamp

[0046] The motor 8 drives the lead screw 3 to rotate, so that the two clips slide toward each other together with the corresponding disc seats 4. When the two clips are moved to the appropriate clamping points, the No. II hydraulic cylinder 17 pushes the variable block 20 forward, that is, the clip clamps the paper under its own elastic force
