Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0029] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Please refer to Figures 1 to 7 The embodiment of the utility model provides a cost-saving and efficient net-pulling machine, comprising a frame 1 erected on the ground, a telescopic mechanism 2 arranged at the lower part of the frame 1, a side clamping mechanism 3 symmetrically arranged on both sides of the telescopic mechanism 2, a front end clamping mechanism 4 arranged at the front end of the telescopic mechanism 2, and a mesh frame conveying mechanism 5 arranged at the rear end of the telescopic mechanism 2, wherein the mesh frame conveying mechanism 5 comprises a conveying platform 51 arranged at the rear end of the telescopic mechanism 2, and a mesh 52 rotatably arranged at one end of the conveying platform 51 away from the frame 1; a conveying port 511 is provided in the middle of the conveying platform 51 for placing the mesh frame 6 and the mesh 52 on the frame 1, the mesh frame 6 enters the frame 1 through the conveying port 511, and the mesh 52 enters the top of the frame 1 through the conveying port 511 and is clamped and stretched by the front end clamping mechanism 4 and the side clamping mechanism 3 accordingly.

[0031] When it is necessary to pull the net, the production staff can first apply glue on the mesh frame 6 and wait for the glue on the mesh frame 6 to dry. At the same time, the production staff places the mesh 52 on top of the frame 1 through the conveying port 511, and starts the telescopic mechanism 2 to move the front end clamping mechanism 4 and the side clamping mechanism 3 inward, so that the front end clamping mechanism 4 and the side clamping mechanism 3 are close to the mesh 52, and the front end clamping mechanism 4 is adjusted accordingly to clamp the front end of the mesh 52, and the side clamping mechanism 3 is adjusted to clamp the two sides of the mesh 52 respectively, and at the same time, the telescopic mechanism 2 is started to drive the front end clamping mechanism 4 and the side clamping mechanism 3 to move outward to tighten the mesh 52, so that the tension of the mesh 52 is uniform to prevent the mesh 52 from breaking. Then the production staff sequentially puts the mesh frame 6 with dried glue into the frame 1 through the conveying port 511, starts the telescopic mechanism 2 to lift the mesh frame 6 on the frame 1, so that the mesh 52 is laid on the mesh frame 6, and then the mesh frame 6 and the mesh 52 can be removed together to complete the processing steps. The whole process is simple and convenient, and effectively avoids the situation that the mesh 52 may stick to the glue that has not dried on the mesh frame 6 when pulling the net, resulting in the mesh 52 being unable to be stretched on the mesh frame 6 normally, and the mesh 52 can be tightened synchronously while waiting for the glue of the mesh frame 6 to dry, saving time and improving production efficiency. By tightening the mesh 52 first and then placing it in the mesh frame 6, the area widened when the mesh 52 is tightened is saved, and the saved part can be reused, saving raw materials, further improving production efficiency, and reducing production costs.

[0032] In order to prevent the glue that has not completely dried on the mesh frame 6 from adhering to the mesh 52, the initial height of the rack 1 is lower than the height of the lowest point of the conveying port 511. For example, the height of the mesh frame 6 is 5 cm, and the height of the conveying port 511 is more than 5 cm, thereby reserving sufficient space for the height of the mesh frame 6 and the mesh 52 to facilitate the insertion of the mesh frame 6 and the mesh 52 respectively. The initial height of the rack 1 is lower than the height of the lowest point of the conveying port 511, thereby facilitating the insertion of the mesh frame 6 without directly contacting the mesh 52, thereby preventing the glue that has not completely dried on the mesh frame 6 from adhering to the mesh 52.

[0033] Regarding the specific structural setting of the telescopic mechanism 2, as shown in FIG. Figure 4 and Figure 5As shown, the telescopic mechanism 2 includes a side telescopic assembly 21 arranged in the lower part of the frame 1, a height telescopic assembly 22 arranged in the lower part of the frame 1, and a two-end telescopic assembly 23 arranged in the lower part of the frame 1. The side telescopic assembly 21 controls the two sets of side clamping mechanisms 3 to shrink toward the frame 1 or to move away from the frame 1. The height telescopic assembly 22 controls the upper part of the frame 1 to lift and lower, so that the net frame 6 placed thereon is driven to lift and lower, and then the mesh 52 is laid on the net frame 6 to complete the processing steps. The two-end telescopic assembly 23 controls the front clamping mechanism 4 and the mesh frame conveying mechanism 5 to shrink toward the frame 1 or to move away from the frame 1. By setting the telescopic mechanism 2, the side clamping mechanism 3, the front clamping mechanism 4, and the mesh frame conveying mechanism 5 can be adjusted to different positions, suitable for net frames 6 and mesh 52 of different sizes, and further improve the practicality of the net drawing machine.

[0034] Regarding the specific structural setting of the side telescopic assembly 21, as shown in FIG. Figure 4 and Figure 5 As shown, the side telescopic assembly 21 includes a side main reduction motor 211 arranged in the lower part of the frame 1, a side main transmission shaft 212 arranged in the side main reduction motor 211 and extending to both ends, a side sub-transmission worm gear reducer 213 respectively connected to both ends of the side main transmission shaft 212 and perpendicular to the side main transmission shaft 212, a side sub-transmission shaft 214 correspondingly arranged in the side sub-transmission worm gear reducer 213 and extending to both sides, and a side sub-nut sleeve 215 respectively correspondingly arranged on both sides of the side sub-transmission shaft 214, and the side clamping mechanism 3 is correspondingly arranged on the side sub-nut sleeve 215. When it is necessary to adjust the two sets of side clamping mechanisms 3 to shrink toward the frame 1 or move away from the frame 1, it is only necessary to start the side main reduction motor 211, and the side main reduction motor 211 drives the side main transmission shaft 212 to rotate, and the side main transmission shaft 212 drives the side sub-transmission worm gear reducer 213 to transmit, so that the side sub-transmission shaft 214 perpendicular to the side main transmission shaft 212 is driven by the side sub-transmission worm gear reducer 213 to rotate, so that the side sub-nut sleeve 215 connected to the side sub-transmission shaft 214 is screwed by the side sub-transmission shaft 214, thereby driving the side clamping mechanism 3 arranged thereon to shrink toward the frame 1 or move away from the frame 1, completing the net drawing processing step.

[0035] Regarding the specific structural arrangement of the side clamping mechanism 3, as shown in FIG. Figure 1 and Figure 6As shown, the side clamping mechanism 3 includes a side support frame 31 arranged on the side nut sleeve 215, a plurality of side clamping cylinders 32 placed in the side support frame 31 and with output shafts extending through the upper end of the side support frame 31, a side clamping lever 33 respectively arranged on the output shaft of the side clamping cylinder 32, a side pressing limiter 34 arranged on the side of the side clamping lever 33 away from the frame 1 and whose lower end face is pressed against the side support frame 31 when the side clamping lever 33 is driven to retract by the side clamping cylinder 32, and a side clamping plate 35 fixed to the side of the side clamping lever 33 close to the frame 1 and which presses the mesh 52 against the side support frame 31 when the side clamping cylinder 32 is driven to retract. When the side clamping mechanism 3 is needed to clamp the side of the mesh 52, it is only necessary to place the mesh 52 transmitted from the transmission port 511 between the side support frame 31 and the side clamping plate 35, start the side clamping cylinder 32, and retract the side clamping cylinder 32, thereby driving the side clamping lever 33 connected to the side clamping cylinder 32 to be pressed downward. At this time, one end of the side clamping cylinder 32 close to the side clamping plate 35 is pressed against the side support frame 31, and the side pressing limit piece 34 at the other end of the side clamping lever 33 is driven downward at the same time, and its lower end is pressed against the side support frame 31. The side clamping cylinder 32 continues to drive the side clamping lever 33 to retract. Since the lower end of the side pressing limiter 34 has been pressed against the side support frame 31, and the upper end is fixed on the side clamping lever 33, the side clamping lever 33 is tilted toward the side clamping plate 35, so that the side clamping plate 35 presses the mesh 52 more firmly against the side support frame 31. The side clamping cylinder 32 is simple in structure, easy to use, low in cost, time-saving and labor-saving, and during the retraction of the side clamping cylinder 32, the user can adjust the mesh 52 in time to prevent uneven force and improve production efficiency. The structure of the side clamping cylinder 32 arranged in the side support frame 31 leaves a large operating space above the side support frame 31, avoiding the problem that the user is difficult to adjust the mesh 52 due to too many cylinders on the side support frame 31. The side clamping plate 35 does not need to be fixed on the side clamping lever 33. The mesh 52 is placed between the side clamping plate 35 and the side support frame 31. When the side clamping cylinder 32 drives the side clamping cylinder 32 to retract, the side clamping lever 33 presses and pushes down the side clamping plate 35 to compress the mesh 52. The decision can be made according to actual conditions.

[0036] Regarding the specific structural setting of the telescopic components 23 at both ends, as shown in FIG. Figure 4 and Figure 5As shown, the two-end telescopic assembly 23 includes a two-end main reduction motor 231 arranged in the lower part of the frame 1, a two-end main transmission shaft 232 arranged in the two-end main reduction motor 231 and extending to both sides, a two-end sub-transmission worm gear reducer 233 respectively connected to both sides of the two-end main transmission shaft 232 and perpendicular to the two-end main transmission shaft 232, a two-end sub-transmission shaft 234 correspondingly arranged in the two-end sub-transmission worm gear reducer 233 and extending to both ends, a front end nut sleeve seat 235 correspondingly arranged at the front end of the two-end sub-transmission shaft 234, and a rear end nut sleeve seat 236 correspondingly arranged at the rear end of the two-end sub-transmission shaft 234, the front end clamping mechanism 4 is arranged on the front end nut sleeve seat 235, and the mesh frame transmission mechanism 5 is arranged on the rear end nut sleeve seat 236. When it is necessary to adjust the front-end clamping mechanism 4 and the mesh frame conveying mechanism 5 to shrink toward the frame 1 or move away from the frame 1, it is only necessary to start the main reduction motors 231 at both ends, so that the main reduction motors 231 at both ends drive the main transmission shafts 232 at both ends to rotate, and the main transmission shafts 232 at both ends drive the sub-transmission worm gear reducers 233 at both ends to transmit, so that the sub-transmission shafts 234 at both ends perpendicular to the main transmission shafts 232 at both ends are driven by the sub-transmission worm gear reducers 233 to rotate, so that the front-end nut sleeve 235 and the rear-end nut sleeve 236 connected to the sub-transmission shafts 234 at both ends are screwed, thereby driving the front-end clamping mechanism 4 set on the front-end nut sleeve 235 and the mesh frame conveying mechanism 5 set on the rear-end nut sleeve 236 to shrink toward the frame 1 or move away from the frame 1, completing the net drawing processing step.

[0037] Regarding the specific structural setting of the front end clamping mechanism 4, as shown in FIG. Figure 1 and Figure 7As shown, the front end clamping mechanism 4 includes a front end support frame 41 arranged on the front end nut sleeve 235, a plurality of front end clamping cylinders 42 placed in the front end support frame 41 and with the output shaft passing through the upper end of the front end support frame 41, a front end clamping lever 43 respectively arranged on the output shaft of the front end clamping cylinder 42, a front end pressing limiter 44 which is arranged at one end of the principle frame 1 of the front end clamping lever 43 and whose lower end face is pressed against the front end support frame 41 when it is driven to retract by the side clamping cylinder 32, and a front end clamping plate 45 which is fixed to one end of the front end clamping lever 43 close to the frame 1 and presses the mesh 52 against the front end support frame 41 when it is driven to retract by the front end clamping cylinder 42. When the front-end clamping mechanism 4 is needed to clamp the front end of the mesh 52, it is only necessary to place the mesh 52 transmitted from the transmission port 511 between the front-end support frame 41 and the front-end clamping plate 45, start the front-end clamping cylinder 42, retract the front-end clamping cylinder 42, and drive the front-end clamping lever 43 connected to the front-end clamping cylinder 42 to be pressed downward. At this time, one end of the front-end clamping cylinder 42 close to the front-end clamping plate 45 is pressed against the front-end support frame 41, and the front-end pressing limit piece 44 at the other end of the front-end clamping lever 43 is driven downward at the same time, and its lower end is pressed against the front-end support frame 41. The front clamping cylinder 42 continues to drive the front clamping lever 43 to retract. Since the lower end of the front pressure limiter 44 has been pressed against the front support frame 41, and the upper end is fixed on the front clamping lever 43, the front clamping lever 43 is tilted toward the front clamping plate 45, so that the front clamping plate 45 can press the mesh 52 more firmly against the front support frame 41. It has a simple structure, is easy to use, has a low cost, saves time and effort, and during the retraction of the front clamping cylinder 42, the user can adjust the mesh 52 in time to prevent uneven force and improve production efficiency. The structure of the front clamping cylinder 42 set in the front support frame 41 leaves a large operating space above the front support frame 41, avoiding the problem that the user has difficulty adjusting the mesh 52 due to too many cylinders on the front support frame 41. The side clamping plate 35 does not need to be fixed on the side clamping lever 33. The mesh 52 is placed between the side clamping plate 35 and the side support frame 31. When the side clamping cylinder 32 drives the side clamping cylinder 32 to retract, the side clamping lever 33 presses and pushes down the side clamping plate 35 to compress the mesh 52. The decision can be made according to actual conditions.

[0038] Regarding the specific structural setting of the highly telescopic component 22, as shown in FIG. Figure 4 and Figure 5 As shown, the height telescopic component 22 includes a height telescopic reduction motor 221 arranged in the lower part of the frame 1, and a height telescopic frame 222 respectively arranged in the frame 1 and connected to the output shaft of the height telescopic motor 221.

[0039] Regarding the specific structural setting of the frame 1, as shown in FIG. Figure 1 and Figure 4 As shown, the frame 1 includes a ground support frame 11 erected on the platform, and a support plate 12 arranged on the height telescopic frame 222; the side telescopic components 21, the two end telescopic components 23, and the height telescopic components 22 are arranged on the ground support frame 11. The mesh frame 6 is placed on the support plate 12 through the conveying port 511. When it is necessary to lift the mesh frame 6 so that the mesh 52 is laid on the mesh frame 6, it is only necessary to start the height telescopic reduction motor 221, and the height telescopic reduction motor 221 lifts the height telescopic frame 222, and the height telescopic frame 222 lifts the support plate 12, so that the mesh frame 6 placed on the support plate 12 is lifted, and then the mesh 52 is laid on the screen, and then the mesh frame 6 and the mesh 52 can be taken down together to complete the processing steps.

[0040] As for the connection mode between the height telescopic reduction motor 221 and the height telescopic frame 222 (not shown in the figure), a connecting rod may be installed between the two sets of height telescopic frames 222, and the height telescopic reduction motor 221 may be installed with an axis body perpendicular to the connecting rod, so that the height telescopic reduction motor 221 can simultaneously lift up the two sets of height telescopic frames 222. A worm gear reduction motor or the like may also be used for vertical steering, and its lifting structure and method are conventional technical means in the industry, and its specific structure may be set according to actual conditions, so no specific limitation is made in this embodiment.

[0041] In order to prevent the mesh 52 from being easily broken due to the height difference with the front clamping mechanism 4 and the side clamping mechanism 3 when the mesh 52 is inserted, the height of the conveying port 511 is flush with the plane height of the side support frame 31 and the front support frame 41 used to press the mesh 52, thereby preventing the mesh 52 from being easily broken due to the height difference with the front clamping mechanism 4 and the side clamping mechanism 3 when the mesh 52 is inserted.

[0042] It should be noted that the economical and efficient mesh-drawing machine disclosed in the utility model is an improvement on the specific structure, and the specific control method is not the innovation point of the utility model. The cylinder, reduction motor, worm gear reduction motor, mesh, mesh frame and other components involved in the utility model can be general standard parts or components known to those skilled in the art, and their structures, principles and control methods are all known to those skilled in the art through technical manuals or conventional experimental methods.
