Description

Technical Field

[0001] The utility model belongs to the technical field of box nailing machines, and in particular relates to a box nailing and flattening splint of a semi-automatic box nailing machine. Background Art

[0002] A semi-automatic carton stapler is a type of mechanical equipment used for the binding of cartons. It is generally horizontal and comes in two types: single-piece and double-piece. Currently, semi-automatic carton staplers are widely used to process various cartons due to their high production efficiency, uniform staple spacing, and aesthetically pleasing appearance.

[0003] A search of CN219988603U5 disclosed a carton flattening splint of a semi-automatic carton stapler, which drives the threaded rod to rotate by rotating the hand wheels on both sides, and pushes the limit splints on both sides to move on the top of the slide slot through the threaded rod, thereby adjusting the distance between the limit splints on both sides, and clamping and limiting the two sides of the carton; compared with the existing technology, this design can improve the efficiency of adjustment to a certain extent, thereby improving the binding efficiency of the carton and facilitating the binding processing of the carton.

[0004] During the movement of the clamping plate, the two are independent of each other. Therefore, when the adjustment distances of the threaded rods on both sides are not equal, the restricted cardboard cannot be in the center position, resulting in a deviation in the binding position.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0006] In order to solve the above technical problem that when the clamping plates are moving, the two plates are independent of each other. When the distances of the threaded rods on both sides are adjusted to be unequal, the restricted paperboard cannot be in the center position, resulting in the deviation of the binding position, the basic concept of the technical solution adopted by the utility model is:

[0007] A carton nailing and flattening splint of a semi-automatic carton nailing machine, comprising a carton nailing machine;

[0008] A support frame is fixedly connected to the top of the nailing machine. An adjusting and flattening mechanism is provided inside the nailing machine. An auxiliary flattening mechanism is provided above the adjusting and flattening mechanism. The adjusting and flattening mechanism includes a limiting slot provided on the top of the nailing machine:

[0009] The top end of the lifting link is fixedly provided with a spring, and the bottom end of the spring is fixedly provided with a spring, and the bottom end of the spring is fixedly connected to the sliding link of the sliding link.

[0010] As a preferred embodiment of the present invention, the auxiliary flattening mechanism includes an electric telescopic rod fixedly connected to the bottom end of the support frame, the output end of the electric telescopic rod is fixedly connected to a pressure plate, the bottom end of the pressure plate is fixedly connected to a roller, and a conveyor belt is provided on the nailing machine.

[0011] As a preferred embodiment of the present invention, the outer walls on both sides of the top block are provided with inclined surfaces, and there are two force-bearing blocks, which are distributed on the left and right sides of the top block in a bilaterally symmetrical structure.

[0012] As a preferred embodiment of the present invention, the inner wall of the sliding sleeve fits in contact with the outer wall of the sliding rod, and the inner wall of the limiting groove fits in contact with the outer wall of the connecting rod.

[0013] As a preferred embodiment of the present invention, the limiting block is made of rubber.

[0014] As a preferred embodiment of the present invention, there are several rollers, and the rollers are evenly and equidistantly distributed at the bottom end of the pressing plate.

[0015] As a preferred embodiment of the present invention, the pressing plate and the roller are located at the center of the support frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] When the push rod is pulled backward, the force-bearing block is gradually no longer squeezed by the top block, and the rebound of the spring will drive the force-bearing blocks to move closer to each other, thereby driving the limiting splints on both sides to move closer to each other, so that the distance between the limiting splints on both sides is consistent during the movement, thereby ensuring that the position of the cardboard is in the center of the nailing machine and preventing the subsequent nailing position from being offset.

[0018] The utility model clamps and limits the two ends of the cardboard by adjusting the flattening mechanism, and then starts the electric telescopic rod, the output end of which will drive the pressing plate to move downward, and the movement of the pressing plate will drive the roller to move downward, so that the bottom end of the roller contacts and presses against the top end of the cardboard, and then the other end of the cardboard contacts the conveyor belt, and the cardboard is transmitted through the conveyor belt, and then nailed, so that there is no need to manually press the cardboard all the time, thereby improving the nailing efficiency and reducing the labor intensity.

[0019] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0027] like Figures 1 to 4 As shown, a nailing and flattening splint of a semi-automatic nailing machine includes a nailing machine 1, a support frame 2 fixedly connected to the top of the nailing machine 1, an adjusting flattening mechanism 31 is provided inside the nailing machine 1, and an auxiliary flattening mechanism 32 is provided above the adjusting flattening mechanism 31, the adjusting flattening mechanism 31 includes a limiting groove 311 opened at the top of the nailing machine 1, a connecting rod 312 is movably provided inside the limiting groove 311, the bottom end of the connecting rod 312 is fixedly connected to a force block 313, the end of the connecting rod 312 away from the force block 313 is fixedly connected to a limiting splint 3114, the outer wall of the force block 313 is fixedly connected to a supporting connecting rod 314, and the outer wall of the supporting connecting rod 314 away from the force block 313 is fixedly connected to a sliding rod 315. The inner wall of the cavity inside the box nailing machine 1 is fixedly connected with a sliding sleeve 317, and the outer wall of the sliding rod 315 is slidably set on the inner wall of the sliding sleeve 317. The end of the sliding rod 315 away from the supporting connecting rod 314 is fixedly connected with a spring 316, and the end of the spring 316 away from the sliding rod 315 is fixedly connected to the inside of the sliding sleeve 317. A connecting groove is provided on the outer wall of the box nailing machine 1, and a push rod 319 is movably provided on the inner wall of the connecting groove. One end of the push rod 319 is fixedly connected to the top block 318, and the end of the push rod 319 away from the top block 318 is fixedly connected to the baffle 3110. The outer wall of the box nailing machine 1 is fixedly connected to a fixing plate 3111, and the outer wall of the fixing plate 3111 is threadedly connected to a screw rod 3112, and one end of the screw rod 3112 is fixedly connected to a limiting block 3113.

[0028] Furthermore, inclined surfaces are provided on the outer walls on both sides of the top block 318, and there are two force-bearing blocks 313, which are distributed on the left and right sides of the top block 318 in a left-right symmetrical structure. Through the inclined surfaces, the force-bearing blocks 313 on both sides can be squeezed, thereby driving the limiting clamps 3114 on both sides to move.

[0029] Furthermore, the inner wall of the sliding sleeve 317 fits in contact with the outer wall of the sliding rod 315, and the inner wall of the limiting groove 311 fits in contact with the outer wall of the connecting rod 312, thereby ensuring the stability of the sliding rod 315 during movement. At the same time, through the adaptation between the limiting groove 311 and the connecting rod 312, the stability of the limiting clamp 3114 during the clamping process can be guaranteed.

[0030] Furthermore, the material of the limiting block 3113 is rubber, so when the limiting block 3113 contacts the outer wall of the push rod 319, the friction between the two can be increased, thereby improving the limiting stability.

[0031] The auxiliary flattening mechanism 32 includes an electric telescopic rod 321 fixedly connected to the bottom end of the support frame 2, the output end of the electric telescopic rod 321 is fixedly connected to a pressing plate 322, the bottom end of the pressing plate 322 is fixedly connected to a roller 323, and a conveyor belt 324 is provided on the nailing machine 1.

[0032] Furthermore, there are a plurality of rollers 323 , which are evenly and equidistantly distributed at the bottom end of the pressing plate 322 , so as to perform contact pressing from one end of the cardboard to the other end, thereby ensuring the stability of the cardboard during movement.

[0033] Furthermore, the pressing plate 322 and the roller 323 are located at the center of the support frame 2, which can press the center of the cardboard, thereby ensuring that the cardboard is located at the center and ensuring the accuracy of the subsequent nailing position.

[0034] The implementation principle of the nailing box flattening splint of a semi-automatic nailing machine of this embodiment is as follows: when facing cardboards of different sizes, the screw rod 3112 is first reversed, so that the screw rod 3112 drives the limit block 3113 to move to the right, thereby moving away from the outer wall of the push rod 319, releasing the limiting effect on the push rod 319, and then pulling the push rod 319 forward or backward. When the push rod 319 moves forward, it will drive the top block 318 to move forward. At this time, the outer wall of the top block 318 will contact and squeeze the force block 313. The squeezed force block 313 will drive the top connecting rod 312 to move to the left and right sides. The movement of the connecting rod 312 can drive the limit splint 3114 at its top to move away from each other, thereby increasing the limit on both sides. When the push rod 319 is pulled back, the force-bearing block 313 is gradually no longer squeezed by the top block 318, and the rebound of the spring 316 will drive the force-bearing blocks 313 to move closer to each other, thereby driving the limiting clamps 3114 on both sides to move closer to each other, so as to ensure that the distance moved by the limiting clamps 3114 on both sides during the movement is consistent, thereby ensuring that the position of the cardboard is in the center of the nailing machine 1 and preventing the subsequent nailing position from deviating.

[0035] After the two ends of the cardboard are clamped and limited by adjusting the flattening mechanism 31, the electric telescopic rod 321 is started, and its output end will drive the pressing plate 322 to move downward. The movement of the pressing plate 322 will drive the roller 323 to move downward, so that the bottom end of the roller 323 contacts and presses against the top end of the cardboard. Then, the other end of the cardboard contacts the conveyor belt 324, and the cardboard is transported by the conveyor belt 324 and then nailed. Therefore, there is no need to manually press the cardboard all the time, which improves the nailing efficiency and reduces the labor intensity.
