Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of biological pharmaceutical process technology, specifically relates to a cover plate, drying clamp and fixing device. BACKGROUND

[0002] Deep filter is an important equipment in biological pharmaceutical process technology, and deep filter paperboard is the filter medium of deep filter. The deep filter paperboard is usually divided into hydrophilic paperboard and hydrophobic paperboard. The hydrophilic paperboard is usually composed of wood pulp fiber, filter aid and wet strength agent. The hydrophobic paperboard is usually composed of wood pulp fiber, synthetic fiber, filter aid and wet strength agent. Among them, the fiber can provide a three-dimensional framework, the filter aid can adsorb impurities, and the wet strength agent can play a sticking role to make the paperboard have certain wet strength.

[0003] During the drying process of the deep filter paperboard, the wood pulp fiber and synthetic fiber are prone to shrinkage under heat, which adversely affects the shape and size of the finished product. Therefore, it is necessary to fix the deep filter paperboard and apply pressure during the drying process to reduce the impact of deformation on the finished product. During the drying process of the existing deep filter paperboard, a perforated plate is usually used to press from above to prevent the paperboard from shrinking and deforming.

[0004] Chinese patent CN220314355U discloses a paperboard transfer clamp, which comprises an upper plate, a through rod provided on the upper plate, a horizontal plate strip installed on the through rod, a connecting rod installed on the horizontal plate strip, a spring sleeved on the connecting rod, a folded plate provided on the connecting rod, a concave piece installed on the folded plate, a pair of rotating seats installed on the concave piece, rotating shafts provided on each rotating seat, eccentric wheels provided on the rotating shafts, support plates provided on the eccentric wheels, waist-shaped holes provided on the support plates, inner push plates sleeved on the connecting rod, lower backing plates installed at the lower ends of each pair of inner push plates on the same side, upper pull rods inserted into the waist-shaped holes, concave upper pull pieces provided on the upper pull rods, upper horizontal plates installed on the concave upper pull pieces, middle connecting plates provided between the upper horizontal plates, concave mounting pieces installed between the horizontal plate strips, upper lifting cylinders installed on the concave mounting pieces, and the upper ends of the upper lifting cylinders are provided on the middle connecting plates. By setting the clamp on the traction rope of the hoisting device, when transferring multiple paperboards, the paperboards can be stably clamped and limited, thereby avoiding the phenomenon of paperboard falling during the transfer of the paperboard. This patent is mainly used for the transfer clamp of ordinary paperboard to avoid the falling of the paperboard during the transfer, and cannot meet the fixing and drying requirements of the deep filter paperboard.

[0005] A paperboard production line special clamp is disclosed in Chinese patent CN212601471U, which comprises a base, a supporting mechanism and a clamping mechanism. The clamping mechanism is installed above the base. The supporting mechanism comprises a first supporting mechanism and a second supporting mechanism, and the first supporting mechanism and the second supporting mechanism are respectively arranged in parallel on both sides of the clamping mechanism. The clamping mechanism comprises two fixed blocks, a clamping slide rail, two springs, two sliding blocks and two clamping plates. The paperboard is arranged between the two clamping plates. This patent improves the processing of packaging products such as corrugated boxes and paper boxes. The paperboard special clamp for positioning and fixing paperboard on the paperboard production line cannot meet the needs of fixing and drying deep filtration paperboard.

[0006] In summary, the existing paperboard clamp has the following problems:

[0007] (1) The flat pressing of the multi-hole plate will produce indentations on the upper surface of the paperboard, which will change the shape of the upper surface of the paperboard. The product with shape requirements on the surface is not suitable.

[0008] (2) The multi-hole plate needs a certain weight to ensure that the paperboard does not shrink and deform when pressed on the paperboard. At the same time, the multi-hole plate cannot be too heavy, otherwise it will change the thickness of the deep filtration paperboard and affect the performance of the paperboard.

[0009] (3) The multi-hole plate is mostly manually transported, which requires a certain amount of manpower.

[0010] (4) The existing clamp has single function and complex structure, and cannot meet the fixing and drying needs of paperboards of various sizes. SUMMARY
