Referring to fig. 2-4, the present invention provides a fiberboard blank pre-pressing device, which comprises a base (not shown in the figure), an upper conveyer belt 2 'and a lower conveyer belt 3' which are arranged on the base, a prepressing space is formed between the upper conveyer belt 2 'and the lower conveyer belt 3', the two sides of the prepressing space are symmetrically provided with a guide plate 4 and a supporting frame 5 fixedly connected with the guide plate 4, the supporting frame 5 is provided with at least two horizontal sliding rods 51, the horizontal sliding rods 51 are connected with vertical sliding rods (not shown in the figure) fixed on the base through an adjusting sliding sleeve 6, the adjusting sliding sleeve 6 comprises a horizontal hollow sleeve body 61 and a vertical hollow sleeve body 62, the horizontal hollow sleeve 61 is provided with a first fixing hole 63 perpendicular to its axis for inserting a bolt, the vertical hollow sleeve 62 is provided with a second fixing hole 64 perpendicular to its axis for inserting a bolt.
Because the structure of pre-compaction space both sides is the symmetry setting, for the convenience of explanation and understanding, fig. 3 has only been drawn the three-dimensional decomposition sketch map of the partial structure of pre-compaction space one side, promptly the utility model discloses the three-dimensional decomposition sketch map of the structure of improvement part on the basis of current preformer technique, including guide plate 4, support frame 5, horizontal sliding rod 51 and adjusting sliding sleeve 6. The operation of these structures will be further described below.
The symmetry sets up pre-compaction space both sides guide plate 4 be used for with slab 1 contact, it is right the protection is supported to the both sides of slab 1, the guarantee slab 1 is at the integrality of pre-compaction in-process both sides edge, avoids the fiber material of slab in pre-compaction in-process both sides not hard up or drop, promotes the qualification rate of pre-compaction fashioned plate. The gap between the deflector 4 and the upper conveyor belt 2 'and the lower conveyor belt 3' is 2-8mm, so that the deflector 4 is prevented from influencing the operation of the upper conveyor belt 2 'and the lower conveyor belt 3'.
The guide plate 4 only needs to ensure that the inner surface in contact with the slab 1 is smooth, therefore, it can use the smooth material in surface such as PE panel, the area of guide plate 4 may be great, consequently, through setting up support frame 5, can ensure guide plate 4 levels indeformable, can be convenient for adjust moreover guide plate 4's position. The supporting frame 5 can be made of steel section bars in a welding mode, so that the strength is guaranteed, and meanwhile the supporting frame is convenient to process by using a welding process.
