Description

Technical Field

[0001] The utility model relates to the technical field of paper-molding equipment, in particular to a pulp molding equipment. Background Art

[0002] As the demand for paper-plastic packaging in the packaging industry increases, it is necessary to improve the efficiency of paper-plastic molding and reduce the production cycle of products in order to meet the needs of mass production of paper-plastic products.

[0003] Common paper-plastic molding machines use the fact that hot pressing takes the longest time in the molding cycle of paper-plastic products. An additional molding upper mold is set around the pulp pool of the equipment. The two molding upper molds perform the dehydration process in turn, which reduces the waiting time of the pulp pool during the hot pressing process and increases the working saturation of the pulp pool, thereby improving production efficiency. In order to avoid interference between the two molding upper molds during movement, a corresponding number of molding lower molds need to be set. Correspondingly, the equipment is also provided with two discharge ports, and the two discharge ports are set on two opposite sides of the pulp pool. This increases the difficulty of collecting materials, and requires the design of two material conveying lines, which further increases the floor space of the equipment.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a pulp molding device to collect and integrate materials and optimize the volume of the device.

[0006] The technical solution of the utility model is as follows:

[0007] A pulp molding device comprises a dewatering mechanism, a shaping mechanism, a moving mechanism and a clamping mechanism; the dewatering mechanism comprises a transversely arranged bidirectional moving assembly; the shaping mechanism comprises two lower molding dies, and along the length direction of the bidirectional moving assembly, the two lower molding dies are arranged on opposite sides of the dewatering mechanism; the moving mechanism comprises a fixed rod transversely arranged on the sides of the dewatering mechanism and the shaping mechanism, and two moving assemblies slidably connected to the fixed rod; two clamping mechanisms are provided, and the two clamping mechanisms are respectively connected to the two moving assemblies.

[0008] The beneficial technical effects of the utility model are as follows:

[0009] (1) The pulp molding equipment of the utility model is provided with molding lower molds on the opposite sides of the dehydration mechanism to perform two molding processes simultaneously. A moving mechanism is provided, and the moving mechanism is connected to two moving components simultaneously through a fixed rod. The two moving components are respectively connected to the driving clamping mechanism to perform material unloading at two positions. After the two clamping mechanisms clamp the material, they can move along the fixed rod to the same position for unloading, thereby realizing material unloading and integration. The two moving components are centrally arranged on the same side, and the structure is compact.

[0010] (2) Furthermore, the material tray is formed by splicing profiles, and the relative position of the material tray and the moving mechanism can be easily adjusted by using the grooves on the profiles, which can also facilitate the adjustment of the position of the air nozzle fixed on the material tray.

[0011] (3) Furthermore, the secondary transverse slide is connected to the clamping mechanism through a connecting rod, so that the secondary transverse slide is prevented from entering the interior of the shaping mechanism when the clamping mechanism clamps the material. The gap between the components is increased, and the flexibility of the equipment is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Embodiment 1

[0020] Figure 1 The three-dimensional structural schematic diagram of the pulp molding equipment of the utility model is shown. Figure 2 A partial enlarged view of the pulp molding device of the utility model at position A is shown. Figure 3 The figure shows the front view of the pulp molding equipment of the utility model after the moving mechanism and the clamping mechanism are hidden. Figure 1 , Figure 2 and Figure 3 A pulp molding device includes a dewatering mechanism 2 and a shaping mechanism 3 arranged in a frame 1, and a moving mechanism 4 and a clamping mechanism 5 arranged on the outside of the frame 1. The dewatering mechanism 2 includes a transversely arranged bidirectional moving component 21, and the bidirectional moving component 21 drives the molding upper mold 23 to move to the dewatering station or the hot pressing station. The shaping mechanism 3 includes two molding lower molds 31, and along the length direction of the bidirectional moving component 21, the two molding lower molds 31 are arranged on the opposite sides of the dewatering mechanism 2. Specifically, the dewatering mechanism 2 also includes a slurry suction mold 22 and a molding upper mold 23 arranged above the slurry suction mold 22. There are two molding upper molds 23, and the two molding upper molds 23 cooperate with the two molding lower molds 31 to produce simultaneously, and correspondingly, there are two unloading positions.

[0021] The moving mechanism 4 includes a fixed rod 41 arranged transversely on the side of the dehydration mechanism 2 and the shaping mechanism 3, and two moving components 44 slidably connected to the fixed rod 41. Two clamping mechanisms 5 are provided, and the two clamping mechanisms 5 are respectively connected to the two moving components 44, and respectively cooperate with the two molding lower molds 31 to perform the unloading action. After the clamping mechanism 5 clamps the material, it can move along the fixed rod 41 to the same position for unloading, realizing the unloading and integration of the material, and the two moving components 44 are centrally arranged on the same side, and the structure is compact.

[0022] The specific structure of the moving assembly 44 is described below:

[0023] Please refer to Figure 1 and Figure 2 , a synchronization rod 45 is provided between the two moving components 44. Specifically, the distance from the position where the clamping mechanism 5 enters the lower molding die 31 for material removal to the position where the clamping mechanism 5 sends out the clamped material is a fixed value. The synchronization rod 45 ensures that the distance between the two moving components 44 is always consistent when they slide on the fixed rod 41. When one moving component 44 drives the clamping mechanism 5 to the material removal position of the lower molding die 31, the clamping mechanism 5 driven by the other moving component 44 is exactly at the position for sending out the clamped material. The positions of the two clamping mechanisms 5 can be controlled by one control device, which has a simple structure and high position accuracy.

[0024] The moving assembly 44 includes a primary transverse slide 441 connected to the fixed rod 41, which controls the clamping mechanism 5 to move horizontally along the fixed rod 41. The vertical slide 442 connected to the primary transverse slide 441 controls the change of the horizontal height of the clamping mechanism 5. The secondary transverse slide 443 connected to the vertical slide 442 drives the clamping mechanism 5 to enter or move out of the unloading position in the shaping mechanism 3. The secondary transverse slide 443 is also connected to the secondary transverse slide 444, and the secondary transverse slide 444 is connected to the clamping mechanism 5 through a connecting rod 445. The connecting rod 445 directly connects the clamping mechanism 5 instead of the secondary transverse slide 444 to prevent the secondary transverse slide 444 from entering the interior of the shaping mechanism 3 when the clamping mechanism 5 clamps the material. The setting of the connecting rod 445 increases the gap between the components and improves the flexibility of the equipment. The fixed rod 41, the vertical slide 442 and the secondary transverse slide 443 are also provided with guide rails 411 respectively.

[0025] The specific structure of the clamping mechanism 5 is described below:

[0026] Please refer to Figure 1 and Figure 2The clamping mechanism 5 includes a material tray 51 and an air nozzle 53 arranged on the material tray 51. A plurality of air nozzles 53 are arranged. Negative pressure is generated by the air nozzles 53 to absorb and fix the material and discharge the material. The material tray 51 is spliced ​​by profiles 511. The profiles 511 are spliced ​​by the grooves 512 on the profiles 511. The size of the material tray 51 can be easily adjusted to adapt to the molding lower molds 31 of different sizes. The position of the air nozzle 53 can also be easily adjusted by the grooves 512 on the profiles 511. The air nozzle 53 is connected to the grooves 512 of the profiles 511 through the two-way connecting plate 52 or the one-way connecting plate 54. The two-way connecting plate 52 can simultaneously connect and fix two air nozzles 53, and the one-way connecting plate 54 can connect and fix one air nozzle 53. The two-way connecting plate 52 and the one-way connecting plate 54 cooperate to flexibly set the position of the air nozzle 53.

[0027] The specific structure of the fixing rod 41 is described below:

[0028] A rack transmission assembly 42 is provided between the fixed rod 41 and the movable assembly 44. Specifically, the drive motor 43 drives the rack transmission assembly 42 to mesh and move relative to each other. Relative movement between the fixed rod 41 and the primary transverse slide 441, between the primary transverse slide 441 and the vertical slide 442, and between the secondary transverse slide 443 and the secondary transverse slide 444 is achieved through the rack transmission assembly 42 and the drive motor 43. Among them, the rack transmission assembly 42 and the drive motor 43 are used to achieve relative movement, but are not limited to this. For example, relative movement can also be achieved by means of a ball screw. In this way, the drive device for limiting movement can be any type known in the art, and is not limited by the rack transmission assembly 42 and the drive motor 43.

[0029] The specific working process of the utility model is as follows:

[0030] The two molding upper molds 23 and the two molding lower molds 31 are matched one by one and divided into two groups, and the hot pressing molding process is carried out in sequence. When the hot pressing molding process of the first group of molding upper molds 23 and molding lower molds 31 is completed, the first group of moving components 44 close to the first group of molding upper molds 23 and molding lower molds 31 is driven by the driving motor 43 to move along the fixed rod 41, and the horizontal height is adjusted to a suitable position through the vertical slide bar 442. Then the secondary horizontal slide 444 drives the clamping mechanism 5 to extend between the molding upper mold 23 and the molding lower mold 31 of the group, and the hot pressing material is adsorbed by the air nozzle 53. The secondary horizontal slide 444 then drives the clamping mechanism 5 to move out of the first group of molding upper molds 23 and molding lower molds 31. At this time, the hot pressing molding process of the second group of molding upper molds 23 and molding lower molds 31 is also completed. The second group of moving components 44 is driven by the driving motor 43 to move along the fixed rod 41 to the vertical position of unloading. When the second group of moving components 44 moves to the predetermined position, the first group of moving components 44 moves to the position of delivering the material under the drive of the synchronization rod 45. The clamping mechanism 5 controlled by the first group of moving components 44 performs the action of sending out the material, while the clamping mechanism 5 driven by the second group of moving components 44 performs the action of adsorbing and clamping the material. After the two actions are completed, the first group of moving components 44 moves again between the first group of molding upper mold 23 and the molding lower mold 31, and the clamping mechanism 5 driven by the second group of moving components 44 performs the action of sending out the material. Repeat the above steps, the first group of moving mechanisms 4 and the second group of moving mechanisms 4 respectively drive the clamping mechanism 5, and alternately perform the actions of clamping and sending out the material.

[0031] Embodiment 2

[0032] Based on the first embodiment, the second embodiment discloses a clamping mechanism 5 with a support and fixed block on a material tray 51. When the material after hot pressing is fixed on the upper forming die 23 for unloading, the material tray 51 is moved under the upper forming die 23, and a plurality of support and fixed blocks are arranged corresponding to the position of the material on the upper forming die 23, and the support and fixed blocks fit the shape of the material after hot pressing. Under the action of gravity, the material falls and is supported by the fixed blocks to complete unloading.

[0033] It can be seen that the above pulp molding equipment connects two moving assemblies 44 through a fixed rod 41 at the same time, and the two moving assemblies 44 are respectively connected to drive the clamping mechanism 5 to discharge materials at two positions. After the two clamping mechanisms 5 clamp the materials, they can move along the fixed rod 41 to the same position for unloading, realizing the unloading and integration of materials, and the two moving assemblies 44 are centrally arranged on the same side, with a compact structure.

[0034] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
