Description

Technical Field

[0001] This utility model belongs to the technical field of floor scrubber filter processing equipment, specifically relating to a semi-automatic pressing device for floor scrubber filter cage covers. Background Technology

[0002] A floor scrubber is a cleaning machine suitable for cleaning hard floors while simultaneously sucking up and removing wastewater from the site. By performing a cycle of clean water, roller brush cleaning, and wastewater recycling, it simulates the daily process of sweeping and mopping. It can clean up particulate debris and remove stubborn stains. The filter is an important component of the floor scrubber, used to filter wastewater and achieve water recycling.

[0003] like Figure 1 and 2 As shown, most existing filters include a cage 1, a cover 2, and a filter screen (not shown in the figure). The cage 1 and cover 2 are mostly injection molded parts. They are connected by a buckle 3 on the cover 2 fastening the retaining ring 4 at the opening end of the cage 1. The traditional fastening method is mostly manual fastening by holding the cage 1 with one hand and the cover 2 with the other. Due to the requirement of sealing, the buckle 3 has a large deformation force when fastening, and a large pressure needs to be applied. However, the overall strength of the cage 1 is low, and it is easy to deform when gripped with a strong grip. If the gripping force is too small, it cannot be fixed. The manual fastening operation is difficult and is prone to defects such as misalignment of the ribs 5 of the buckle 3 and the retaining ring 4, and wrinkles in the rubber coating of the retaining ring 4. The production efficiency is low, the yield rate is low, and it is difficult to meet the needs of mass production. Utility Model Content

[0004] The purpose of this invention is to overcome one or more shortcomings in the prior art and to provide a semi-automatic pressing device for the filter cage cover of a floor scrubber.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is a semi-automatic pressing device for a floor scrubber filter cage cover, comprising a support plate, a clamping assembly disposed on the support plate, and a pressing block. The support plate is provided with a through hole through which the filter cage passes. The clamping assembly is disposed around the through hole and is used to support and fix the retaining ring on the cage. The pressing block is disposed above the through hole and can move up and down. The projection of the pressing block in the vertical direction wraps around the outer side of the projection of the retaining ring in the vertical direction. When the pressing block moves downward to its limit position, it can press the cover pre-attached to the retaining ring into place, thereby achieving pressing.

[0006] Preferably, the clamping assembly includes a movable strip plate disposed above the support plate, the strip plate moving in the radial direction of the retaining ring, the upper surface of the strip plate being flush with the lower end face of the retaining ring, and multiple strip plates being disposed around the through hole.

[0007] More preferably, at least two opposing strips are provided with abutting blocks, the side of the abutting block facing the retaining ring matches the outer wall of the retaining ring, and when the strip moves to below the retaining ring, the abutting block abuts against the outer wall of the retaining ring to achieve clamping.

[0008] More preferably, the abutment block is slidably disposed on the strip, and its sliding direction is the same as the moving direction of the strip on which it is located. The clamping assembly further includes an adjusting bolt for adjusting the position of the abutment block and a locking bolt for locking the position of the abutment block and the strip.

[0009] More preferably, the adjusting bolt passes through the vertical flange of the strip and is threadedly connected to the vertical flange of the abutment block, and the locking bolt passes through the support pad at the bottom of the strip and is threadedly connected to the abutment block.

[0010] More preferably, the clamping assembly further includes a support pad and a clamping cylinder. One end of the support pad is fixedly connected to the bottom of the strip, and the other end is movably connected to the piston rod end of the clamping cylinder. The moving direction of the support pad is perpendicular to the moving direction of the corresponding strip.

[0011] Preferably, the clamping assembly further includes a movable positioning plate and a positioning cylinder for driving the positioning plate to move. The moving direction of the positioning plate is the radial direction of the retaining ring, and the positioning plate is correspondingly arranged with a positioning hole on the cage located below the retaining ring.

[0012] Preferably, the pressing device further includes a support platform with a door frame-shaped bracket, a pressing cylinder connected to and driving the pressing block to move is provided in the middle of the bracket, and a cover covering the bracket and the support plate is provided on the support platform, and a control unit is provided on the cover.

[0013] More preferably, the support plate is horizontally movable above the support platform, and the support plate has a first working position and a second working position. When it is in the first working position, the through hole is located below the pressure block, and the cover completely covers the support plate. When the support plate is in the second working position, the through hole is located outside the pressure block and extends out of the cover.

[0014] More preferably, the support platform is further provided with a shaping component, which includes a U-shaped plate for horizontally fixing the cage and a rotatable shaping column located on one side of the U-shaped plate. The rotation axis of the shaping column is coaxial with the U-shaped plate, and the end face of the shaping column facing the U-shaped plate is inclined.

[0025] like Figures 2 to 8 As shown, the semi-automatic pressing device for the filter cover of the floor scrubber provided by this utility model includes a support platform 10, a bracket 20, a cover 30, a support plate 40, a clamping assembly, and a pressing block 60. The bracket 20 is door-frame shaped and is located on the upper surface of the support platform 10. A pressing cylinder 21 is located in the middle of the crossbeam of the bracket 20. The cover 30 has an opening on its front side, is mounted on the support platform 10 and covers the bracket 20, and has a control unit 31 and control buttons 32. The support plate 40 is movably positioned between the support platform 10 and the bracket 20 and is framed by the bracket 20. The plane of the support plate 40 is parallel to the horizontal plane, and the support plate 40 has a through hole 41 for inserting the filter. The diameter of the through hole 41 of the cage 1 is set according to the size of the cage 1 so that when the cage 1 is inserted, its open end is stuck above the through hole 41. The clamping assembly is set on the support plate 40 and surrounds the through hole 41. The clamping assembly 41 is used to support the retaining ring 4 on the cage 1 and fix it. The pressure block 60 is connected to the piston rod end of the pressing cylinder 21 and is set above the through hole 41 by being driven up and down by the pressing cylinder 21. The pressure block 60 is a cylindrical silicone block. Its projection in the vertical direction wraps around the outside of the projection of the retaining ring 4 in the vertical direction. When the pressing cylinder 21 drives the pressure block 60 to move downward to the limit position, the cover 2 pre-fastened on the retaining ring 4 can be pressed in by the pressure block 60, so as to realize the pressing of the cover 2 and the cage 1.

[0026] The advantage of this setup is that, due to the support and fixation of the retaining ring by the clamping components, the cage and retaining ring will not be deformed, and the cage can be fixed. The pressing block driven by the pressing cylinder can press the cover into the cage to meet the fastening force requirements. The cage only needs to be manually placed into the through hole, supported and fixed by the clamping components, and then the cover is pre-fastened onto the retaining ring. The cover can then be pressed by the pressing block. The operation is simple, the production efficiency is high, the yield rate is high, and it is suitable for mass production.

[0027] In this embodiment, the clamping assembly includes a movable strip 51 disposed above the support plate 40. The moving direction of the strip 51 is the radial direction of the retaining ring 4. The upper surface of the strip 51 is flush with the lower end face of the retaining ring 4. There are three strips 51 arranged around the through hole 41, two of which are generally arranged on opposite sides of the retaining ring 4. The clamping assembly also includes abutting blocks 52 disposed on the two oppositely arranged strips 51. The abutting blocks 52 face the side of the retaining ring 4 and match the outer wall of the retaining ring 4. When the strip 51 moves to the bottom of the retaining ring 4 to form support, the abutting blocks 52 abut against the outer wall of the retaining ring 4 to achieve clamping.

[0028] To facilitate adjustment of the moving distance of the strip 51 and ensure the clamping effect of the abutment block 52, in this embodiment, the abutment block 52 is slidably mounted on the strip 51, and its sliding direction is the same as the moving direction of the strip 51 on which it is located. Furthermore, the clamping assembly also includes an adjusting bolt 53 for adjusting the position of the abutment block 52 and a locking bolt for locking the position of the abutment block 52 and the strip 51. The adjusting bolt 53 passes through the vertical flange 511 of the strip 51 and is threadedly connected to the vertical flange 521 of the abutment block 52. The locking bolt passes through the support pad 512 at the bottom of the strip 51 and is threadedly connected to the abutment block 52. By loosening the locking bolt and then turning the adjusting bolt 53, the position of the abutment block 52 on the strip 51 can be adjusted. After the adjustment is in place, tightening the locking bolt can lock the relative position of the abutment block 52 and the strip 51.

[0029] To facilitate the movement of the rib 5 and the drive strip 51, the clamping assembly further includes a clamping cylinder 55. One end of the support pad 512 is fixedly connected to the bottom of the strip 51, and the other end is movably connected to the piston rod end of the clamping cylinder 55. The moving direction of the support pad 512 is perpendicular to the moving direction of its corresponding strip 51. This movement is achieved through the cooperation of the oblong hole and the bolt. Another strip 51 without the abutment block 52 is also equipped with a clamping cylinder 55 to facilitate driving and avoidance.

[0030] For ease of positioning, in this embodiment, the clamping assembly also includes a movable positioning plate 56 and a positioning cylinder 57 for driving the positioning plate 56 to move. The positioning plate 56 is located on the opposite side of the strip 51 without the abutment block 52. The moving direction of the positioning plate 56 is the radial direction of the retaining ring 4. The positioning plate 56 is correspondingly positioned to the positioning hole 6 on the cage 1 located below the retaining ring 4.

[0031] Since the cover 30 covers the bracket 20 and the support plate 40, in order to facilitate loading and unloading, in this embodiment, the support plate 40 is movably positioned above the support platform 10. The support plate 40 has a first working position and a second working position. When it is in the first working position, the through hole 41 is located below the pressure block 60, and the cover 30 completely covers the support plate 40. When the support plate 40 is in the second working position, a part of the support plate 40 moves forward through the opening of the cover 30, so that the through hole 41 is located outside the pressure block 60 and extends out of the cover 30. In order to facilitate the movement of the support plate 40, the support platform 10 is also provided with a slide rail pair 11, a mating frame 12 and a moving cylinder 13 for the support plate 40 to move. The arrangement can be referred to in the accompanying drawings of this application, or it can be adjusted according to actual needs, which will not be described in detail here.

[0032] Since the retaining ring 4 is coated with rubber, in order to avoid wrinkles during pressing, in this embodiment, the front of the support platform 10 is also provided with a shaping component 70. The shaping component 70 includes a U-shaped plate 71 for horizontally fixing the cage 1, a shaping column 72 located on one side of the U-shaped plate 71 that can rotate, and a motor 73 for driving the shaping column 72 to rotate. The rotation axis of the shaping column 72 is coaxial with the U-shaped plate 71. The end face of the shaping column 72 facing the U-shaped plate 71 is an inclined surface. When the cage 1 is placed in the U-shaped plate 71, the inclined surface abuts against the rubber coating of the retaining ring 4 on the cage 1. At this time, by driving the shaping column 72 to rotate through the motor 73, the rubber coating on the retaining ring 4 can be smoothed out, so that it is in the correct relaxed state, and wrinkles are avoided during pressing.

[0033] For ease of operation, operation buttons 14 are also provided on the left and right sides of the front end of the support platform 10.

[0034] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
