Description

Technical Field

[0001] The utility model relates to the field of paper tray production, and more specifically, to a cutting and forming machine for paper tray production. Background Technique

[0002] Paper tray production is an environmentally friendly and efficient packaging material manufacturing process. It uses renewable resources such as waste paper or sugarcane pulp as raw materials and, through advanced pulp molding technology, converts the raw materials into paper products with good cushioning performance. In the production process, first, the raw materials need to be pretreated, such as being crushed, screened, and impurity-removed, and then formulated into pulp with an appropriate concentration. Then, using a pulp molding machine, the pulp is accurately injected into a special mold. Through pressure drainage, the pulp quickly solidifies and forms into a paper tray with the required shape in the mold. The formed paper tray then enters the drying process, and through heating methods such as hot air or infrared rays, the internal moisture is effectively removed to achieve the desired dryness and stability. Finally, through post-treatment processes such as trimming and cutting, it is ensured that the paper tray meets the size and appearance standards required by customers.

[0003] The texture of the paper tray determines its physical properties and mechanical strength. Different textured paper trays show different anti-cutting performances during die-cutting. Harder paper is more difficult to cut, while softer paper is prone to burrs or tearing during cutting, resulting in an uneven cut seam. The coating or treatment process on the paper surface also affects the cutting effect of the die-cutting tool. Too thick or too slippery a coating will reduce the cutting accuracy. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, a cutting and forming machine for paper tray production is provided to solve the deficiencies that harder paper is more difficult to cut, while softer paper is prone to burrs or tearing during cutting, resulting in an uneven cut seam, and to facilitate use.

[0005] To achieve the above object, the utility model is realized through the following technical solutions:

[0006] A cutting and forming machine for paper tray production includes an outer box and a receiving chamber provided inside the outer box. A die-cutting shear and a transmission mechanism are installed inside the receiving chamber. The die-cutting shear includes two traction shear rods. The transmission mechanism drives the two traction shear rods to perform a shearing operation. Rubber clamping blocks II are respectively installed at the front ends of the two traction shear rods. The rubber clamping blocks II extend outside the outer box. The rubber clamping block I and the rubber clamping block II face each other and both are provided with cut seams. The rubber clamping block I is located above the rubber clamping block II. A cutting knife is installed in the cut seam of the rubber clamping block I, and the position of the cutting knife matches the position of the cut seam of the rubber clamping block II.

[0007] Furthermore, a mounting back plate is installed on the side wall surface of the accommodating groove chamber, and the membrane cutting and transmission mechanism is installed on the side elevation of the mounting back plate. The transmission mechanism includes two meshing driving gears, and a connecting block is installed on the rear end of the mounting back plate close to the membrane cutting side, and two fixed shafts are installed on the connecting block. An arc-shaped limiting slide groove is provided at the front end of the mounting back plate close to the membrane cutting side, and the two driving gears are located between the connecting block and the arc-shaped limiting slide groove. The rear ends of the two traction shear rods are respectively rotated to connect the two fixed shafts, and a traction slide groove is provided in the middle part of the two traction shear rods. A traction block is respectively provided on the side end faces of the two driving gears, and the two traction blocks are respectively inserted into the traction slide grooves on the two traction shear rods. A limit rod inserted into the arc-shaped limit slide groove is respectively provided on the two traction shear rods. When the two driving gears rotate, the traction block cooperates with the traction slide groove to drive the traction shear rod to swing, and the limit rod slides along the arc-shaped limiting slide groove.

[0008] Furthermore, the length of the cutting knife protruding from the bottom surface of the first rubber clamping block is shorter than the depth of the slit in the second rubber clamping block.

[0009] Furthermore, a positioning block is respectively installed on one side of the two film cutting front ends, and the rubber clamping block 1 and the rubber clamping block 2 are respectively installed on the two positioning blocks.

[0010] The utility model has the following beneficial effects:

[0011] 1. The cutting and forming machine for paper tray production of the utility model, through the design of rubber clamp block 1 and rubber clamp block 2, can accurately position and clamp the paper tray up and down before cutting, effectively fix the position of the paper tray, and prevent it from shifting or shaking during the cutting process. The stable clamping state enables the cutting force to act evenly on the paper tray, thereby avoiding uneven cutting or burrs caused by the movement of the paper tray.

[0012] 2. The cutting and forming machine for paper tray production of the utility model ensures the stable swing of the traction shear rod during the cutting process through the coordinated work of the movable shaft, the arc-shaped limit slide groove, the driving gear and the traction block. The movement of the limit rod along the arc-shaped limit slide groove not only limits the range of movement of the traction shear rod, but also provides a stable motion trajectory, reducing the cutting deviation caused by unstable swinging.

[0013] 3. The cutting and forming machine has a simple and compact structure and can be directly installed on the surface of the conveying equipment. The paper support can be continuously fed into the cutting area. With the periodic swing of the traction shear bar, the paper support is continuously fed and cut at the same time. The cutting can be completed in a short time, which improves the smoothness and continuity of the overall production line and further improves production efficiency.

[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0026] Combination Figures 1 to 3 The utility model is a cutting and forming machine for paper tray production, comprising an outer box 1 and a accommodating tank chamber 2 arranged inside the outer box 1, a mounting back plate 3 is installed on the side wall surface of the accommodating tank chamber 2, a film cutter 4 is arranged on the side elevation surface of the mounting back plate 3, the mounting back plate 3 comprises a plate body 31 located inside the accommodating tank chamber 2 and a connecting block 32 arranged on one side end of the plate body 31, a movable shaft 33 is installed on the surface of the connecting block 32, two movable shafts 33 are arranged, and an arc-shaped limiting slide groove 34 is opened on the other side end of the plate body 31.

[0027] The utility model is further described below in conjunction with embodiments.

[0028] Combination Figures 2 to 4 A driving gear 35 is installed on one side of the arc-shaped limiting sliding groove 34, and two driving gears 35 are provided. The two driving gears 35 are meshed and connected. The side end positions of the two driving gears 35 are both installed with traction blocks 36. The positions of the two traction blocks 36 are relative. Through the rotation of the driving gear 35, the traction shearing rod 41 connected to the movable shaft 33 is driven to complete the reciprocating rotation movement. The film cutting 4 includes a traction shearing rod 41 located on one side of the plate body 31 and a traction sliding groove 42 opened at the middle end position of the traction shearing rod 41. The traction sliding groove 42 is connected to the traction block 36. Two traction shearing rods 41 are provided. One end of the two traction shearing rods 41 is movably connected to the connecting block 32 through the movable shaft 33. The other ends of the two traction shearing rods 41 are both installed with positioning blocks 44. The two traction shearing rods 41 drive the positioning blocks 44 to reach a preset position. A limiting rod 43 is provided on one side of the positioning block 44. One end of the limiting rod 43 is fixedly connected to the traction shearing rod 41, and the other end of the limiting rod 43 is connected to the arc-shaped limiting sliding groove 34.

[0029] In this implementation, a second rubber clamping block 46 is provided on the bottom surface of the upper positioning block 44, and a first rubber clamping block 45 is installed on the upper surface of the lower positioning block 44.

When the two traction blocks 36 are close to each other, the included angle between the two traction scissors rods 41 gradually becomes smaller until they are parallel. When the two traction blocks 36 are far away from each other, the included angle between the two traction scissors rods 41 gradually becomes larger. By using the connection between the limiting rod 43 and the arc-shaped limiting chute 34, the movement of the two traction scissors rods 41 is limited to maintain the stability of the operation.

[0031] Through the conveying device, the paper tray is sent between the two positioning blocks 44. As the included angle between the two traction scissors rods 41 gradually becomes smaller, the first rubber clamping block 45 and the second rubber clamping block 46 are closely attached to the upper and lower end faces of the paper tray, so as to position and clamp the support up and down. The included angle between the two traction scissors rods 41 continues to become smaller, and the cutting knife 48 contacts the paper tray. When the cutting knife 48 enters the lower slit 47, the cutting of the paper tray is completed.
