Description

Technical Field

[0001] This utility model relates to the field of plate washing machine technology, and in particular to a pressing cylinder device for a plate washing machine. Background Technology

[0002] The existing plate washing machine uses a cylinder to adjust the height of the upper and lower rollers. After a period of use, the cylinders are prone to wobbling, which can cause damage to the cylinders or cause the upper and lower rollers to be out of alignment. Moreover, the cylinder extension and installation height need to be precisely adjusted to ensure that the upper roller presses down on the mirror steel plate being cleaned. If the extension and retraction of the cylinders above the two ends of the upper roller are different, one end of the upper roller can press down on the mirror steel plate while the other end is separated from the mirror steel plate, causing the mirror steel plate to deviate. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned problems existing in the prior art and to provide a pressing cylinder device for a plate washing machine.

[0004] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0005] A pressing cylinder device for a plate washing machine includes a thin-shaped cylinder with guide rods. A mounting plate is installed at the top of the cylinder body of the thin-shaped cylinder with guide rods. Two internally threaded tubes are fixedly installed on the mounting plate. A cylindrical spring mounting sleeve with a closed top is screwed into each of the internally threaded tubes. The two guide rods of the thin-shaped cylinder with guide rods are respectively inserted into the two spring mounting sleeves. A compression spring is installed in each of the spring mounting sleeves. A pressure rod is clamped between the two compression springs and the tops of the two guide rods of the thin-shaped cylinder with guide rods.

[0006] The internally threaded tube is fitted with a cylindrical waterproof cover that is closed at the top.

[0007] The mounting plate has two limiting strips that are mirror-symmetrical about its long axis at its bottom end, and the top of the thin cylinder with guide rod is locked between the two limiting strips.

[0008] The top of the pressure rod is provided with a piston plate, which is sleeved in the spring mounting cylinder and moves along the axial direction of the spring mounting cylinder. The diameter of the piston plate is equal to the inner diameter of the spring mounting cylinder.

[0009] The inner diameter of the spring mounting cylinder is equal to the diameter of the guide rod of the thin-walled cylinder with guide rod.

[0010] The diameter of the pressure rod is smaller than the diameter of the guide rod of the thin-shaped cylinder with guide rod.

[0011] The pressure rod is coaxial with the adjacent compression spring, internal threaded tube, guide rod of thin-walled cylinder with guide rod, and spring mounting cylinder.

[0012] The beneficial effects of this utility model are: the guide rod of the thin-walled guide rod cylinder itself improves the stability of the thin-walled guide rod cylinder during use, avoids damage caused by cylinder swing, and avoids the upper and lower glue rollers from being out of line due to swing; the restoring force of the compression spring causes the pressure rod to apply downward pressure to the guide rod of the thin-walled guide rod cylinder, thereby causing the movable end plate of the thin-walled guide rod cylinder to drive the lifting plate, bearing seat, and upper glue roller to move downward, so that the upper glue roller presses on the mirror steel plate, without the need to adjust the piston rod extension and retraction of the thin-walled guide rod cylinder according to the plate thickness.

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 5As shown, a pressing cylinder device for a plate washing machine includes a thin-walled cylinder with a guide rod 1, a lifting plate 2, and a bearing seat 3. The cylinder body 101 of the thin-walled cylinder with a guide rod 1 is mounted on the plate washing machine 100. The movable end plate 103 of the thin-walled cylinder with a guide rod 1 is connected to the top of the lifting plate 2 with fasteners. The bearing seat 3 is mounted to the bottom of the lifting plate 2 with fasteners. An upper rubber roller 4 is installed between two adjacent and coaxial bearing seats 3. The air pipe interface of the thin-walled cylinder with a guide rod 1, which drives the piston rod to rise during inflation, is connected to an air source via an air supply pipe.

[0022] The top of the cylinder body 101 of the thin cylinder with guide rod 1 is equipped with an installation plate 5. The bottom of the installation plate 5 is provided with two limiting strips 501 that are mirror-symmetrical about the long axis of the installation plate 5. The top of the thin cylinder with guide rod 1 is stuck between the two limiting strips 501. The limiting strips 501 play a positioning role in the installation and use of the installation plate 5.

[0023] Two internally threaded tubes 6 are fixedly installed on the mounting plate 5. A through-hole 502 is opened at each end of the mounting plate 5. The internally threaded tubes 6 are installed in the through-hole 502 by welding.

[0024] Each internally threaded tube 6 is screwed with a cylindrical spring mounting sleeve 7 with a closed top. The two guide rods 102 of the thin-walled cylinder 1 with guide rod are respectively inserted into the two spring mounting sleeves 7. The inner diameter of the spring mounting sleeve 7 is equal to the diameter of the guide rod 102 of the thin-walled cylinder 1. The spring mounting sleeve 7 is used to further guide the guide rod 102 of the thin-walled cylinder 1, thereby improving the stability of the thin-walled cylinder 1 and preventing the guide rod and movable end plate 103 of the thin-walled cylinder 1 from swinging during movement. Each spring mounting sleeve 7 is equipped with a compression spring 8. A pressure rod 9 is clamped between the two compression springs 8 and the tops of the two guide rods 102 of the thin-walled cylinder 1. The diameter of the pressure rod 9 is smaller than the diameter of the guide rod 102 of the thin-walled cylinder 1. The pressure rod 9 is coaxial with the adjacent compression spring 8, internally threaded tube 6, guide rod 102 of the thin-walled cylinder 1, and spring mounting sleeve 7.

[0025] A piston plate 901 is provided on the top of the pressure rod 9. The piston plate 901 is sleeved in the spring mounting cylinder 7 and moves along the axial direction of the spring mounting cylinder 7. The diameter of the piston plate 901 is equal to the inner diameter of the spring mounting cylinder 7.

[0026] The internally threaded tube 6 is fitted with a cylindrical waterproof cover 10 with a closed top. The inner diameter of the waterproof cover 10 is equal to the outer diameter of the internally threaded tube 6. The waterproof cover 10 prevents liquid and dirt from splashing onto the internally threaded tube 6 and the spring mounting sleeve 7 during the washing process, thus preventing them from getting dirty.

[0027] In this embodiment, the preferred model of the thin-walled cylinder 1 with guide rod is MGPL63-25. In actual use, the model of the thin-walled cylinder 1 with guide rod is selected according to the required cylinder stroke and cylinder diameter.

[0028] The working principle of this pressing cylinder device is as follows: the restoring force of the compression spring 8 causes the pressure rod 9 to apply downward pressure to the guide rod 102 of the thin-section guide rod cylinder 1, thereby causing the movable end plate of the thin-section guide rod cylinder 1 to move the lifting plate 2, bearing seat 3, and glue roller 4 downward, so that the glue roller presses on the mirror steel plate. It is not necessary to adjust the extension and retraction of the piston rod of the thin-section guide rod cylinder 1 according to the plate thickness. When compressed air is introduced into the thin-section guide rod cylinder 1, the piston rod of the thin-section guide rod cylinder 1 moves upward, thereby causing the lifting plate 2, bearing seat 3, and glue roller 4 to move upward, so that the glue roller 4 separates from the mirror steel plate, thereby enabling the surface of the mirror steel plate to be inspected or the position of the mirror steel plate to be adjusted.

[0029] If this pressing cylinder device is used in squeezing or drying equipment, both air pipe interfaces of the thin guide rod cylinder can be connected to the air source with air supply pipes. The force of the thin guide rod cylinder's extension increases the pressure of the upper glue roller on the board, which helps the upper and lower glue rollers work together to squeeze out the moisture from the surface of the board.
