Abstract
Description
Technical Field
[0001] This utility model relates to the field of developing machine technology, and in particular to a pressing wheel support for a developing machine. Background Technology
[0002] The main function of a developing machine is to reveal the latent patterns on exposed glass substrates. The glass substrates need to be stably transported within the developing machine to undergo multiple processes such as developing, rinsing, and drying. Currently, glass substrates are mainly moved within the developing machine by rollers, primarily through friction between the rollers below the glass. Too many rollers below the glass can easily contaminate the substrate, resulting in poor quality. Reducing the number of rollers to improve quality leads to insufficient friction, hindering substrate transport. Currently, adding pressure rollers above the glass substrate increases the friction between the substrate and the rollers, improving glass movement. However, how to fix the pressure rollers above the glass substrate without affecting existing components of the developing machine remains a problem that urgently needs to be solved.
[0003] Therefore, there is a need for a bracket that can accommodate the additional pressing rollers without interfering with the structure of the developing machine itself. Utility Model Content

[0026] As described in the background section, currently, during glass transport in a developing machine, a pressure roller is added on top of the glass to increase the friction between the glass and the lower transport roller. Therefore, how to install the newly added pressure roller inside the developing machine is a problem that needs to be solved.
[0027] To address the aforementioned problems, this utility model provides a pressing roller bracket for a developing machine, comprising a support portion, a connecting portion, and a clearance portion. The support portion supports the pressing roller assembly, the connecting portion is fixed to the housing of the developing machine, and the clearance portion is used to avoid the transmission roller assembly. While providing support for the pressing roller, the bracket does not affect the original structure of the developing machine and does not interfere with the components of the developing machine itself. The bracket is easy to install, has a simple structure, and facilitates the addition of pressing rollers.
[0028] To make the above-mentioned objectives, features and beneficial effects of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Reference Figures 1 to 6 The bracket provided in this embodiment of the invention is used to install and fix the pressing roller assembly required for transporting glass in a developing machine. The developing machine includes a glass transport mechanism and a housing (not shown). The glass transport mechanism is disposed in the housing and includes a transport roller assembly 10 and a pressing roller assembly 20. The transport roller assembly 10 is disposed below the glass 30 to be transported, and the pressing roller assembly 20 is disposed above the glass 30 to be transported.
[0031] The bracket 100 includes: a support portion 101 for supporting the pressing roller assembly 20; a connecting portion 102 connected to the housing to fix the bracket 100 to the housing; and a clearance portion 103 located between the support portion 101 and the connecting portion 102 for clearance of the transmission roller assembly 10.
[0032] refer to Figure 4aIn this embodiment, the pressing wheel assembly 20 includes a first slide rod 21, a support wheel 22, and a pressing wheel 23. The support wheel 22 and the pressing wheel 23 are both sleeved on the first slide rod 21. The first slide rod 21 is provided with a support wheel 22 and a pressing wheel 23 at both ends. The pressing wheel 23 is located between the support wheels 22 at both ends, that is, the pressing wheel 23 is closer to the center of the first slide rod 21 than the support wheels 22.
[0033] In this embodiment, both the support wheel 22 and the pressing wheel 23 are fixedly mounted on the first slide bar 21 and will not move along the first slide bar 21, ensuring that the position of the pressing wheel 23 above the glass to be transferred will not change.
[0034] In this embodiment, the bracket 100 and the developing machine housing are fixedly connected, and the support wheel 22 is placed on the bracket 100 to fix its position inside the developing machine, thereby fixing the position of the pressing wheel assembly 20 inside the developing machine.
[0035] refer to Figure 5 In this embodiment, the transfer roller assembly 10 includes a second slide rod 11 and a transfer roller 12 sleeved on the second slide rod 11, and the second slide rod 11 is fixed on the housing of the developing machine.
[0036] In this embodiment, the second slide bar 11 is provided with multiple transmission rollers 12. In order to avoid contaminating the glass to be transmitted due to too many transmission rollers 12, and also to avoid insufficient friction due to too few transmission rollers 12, which would affect the transmission of the glass.
[0037] In this embodiment, when the glass to be transferred 30 is transferred within the developing machine, the transfer roller assembly 10 is positioned below the glass to be transferred 30, and the pressing roller assembly 20 is positioned above the glass to be transferred. Specifically, the glass to be transferred 30 has opposing upper and lower surfaces. The transfer roller 12 of the transfer roller assembly 10 contacts the lower surface of the glass to be transferred 30, and the pressing roller 23 of the pressing roller assembly 20 contacts the upper surface of the glass to be transferred 30.
[0038] The friction between the transfer rollers 12 and the glass 30 to be transferred is the driving force for the movement of the glass 30. To reduce contamination of the glass 30 by the transfer rollers 12, the number of transfer rollers 12 is reduced. Therefore, a pressing roller 23 is provided above the glass 30 to increase the friction between the transfer rollers 12 and the glass 30. Furthermore, since the glass 30 is usually covered with products, the pressing roller 23 can only be located on both sides of the glass 30; the first slide bar 21 only has pressing rollers 23 at both ends.
[0039] In this embodiment, the direction perpendicular to the surface of the glass to be transferred 30 is denoted as the first direction X, and the transfer direction parallel to the glass to be transferred 30 is denoted as the second direction Y. The second direction Y is perpendicular to the first direction X, and the direction perpendicular to both the first direction X and the second direction Y is the third direction Z.
[0040] In this embodiment, the first slide bar 21 and the second slide bar 11 extend along the third direction Z, and the bracket 100 provides support force for the support wheel 22 in the first direction X.
[0041] refer to Figure 1 , Figure 2 and Figure 6 A first groove 104 is provided on the support portion 101 along the first direction X, and the support wheel 22 is placed on the first groove 104.
[0042] refer to Figure 4b Specifically, the support wheel 22 includes a first disc 221 and a second disc 222 disposed opposite to each other, and a middle portion 223 connecting the first disc 221 and the second disc 222, the middle portion 223 being placed on the first groove 104.
[0043] In other embodiments, the support wheel 22 may also be an integral disc-shaped structure, with the disc of the support wheel 22 placed directly on the first groove 104.
[0044] In this embodiment, the middle portion 223 is also a disk-shaped structure. The diameters of the first disk 221 and the second disk 222 are equal, and the diameter of the middle portion 223 is smaller than the diameters of the first disk 221 and the second disk 222.
[0045] In this embodiment, the first groove 104 has an opening at the top and bottom and arc segments on both sides. The arc segments are adapted to the shape of the middle part 223 so as to better support the support wheel 22.
[0046] In this embodiment, the first groove 104 has a top opening 105 and a bottom opening 106. In the second direction Y, the width D1 of the top opening 105 is greater than or equal to the diameter of the middle portion 223, and the width D2 of the bottom opening 106 is less than the diameter of the middle portion 223.
[0047] The width D1 of the top opening 105 is greater than or equal to the diameter of the middle portion 223, so that the support wheel 22 can be placed or removed from the top opening 105. Preferably, the width D1 of the top opening 105 is equal to the diameter of the middle portion 223, so that the first groove 104 fits more closely with the middle portion 223 of the support wheel 22.
[0048] The width D2 of the bottom opening 106 is smaller than the diameter of the middle part 223, which can prevent the support wheel 22 from falling out of the bottom opening 106, causing the first groove 104 to be unable to support the support wheel 22.
[0049] In this embodiment, the first groove 104 has a top opening 105, which not only facilitates the placement and removal of the support wheel 22, but also allows the support wheel 22 to adjust its height appropriately in the first direction X when encountering glass of different thicknesses to be transferred, thereby changing the height position of the pressing wheel assembly 20 in the first direction X to adapt to glass of different thicknesses to be transferred.
[0050] In the third direction Z, the thickness d1 of the support portion 101 is less than or equal to the thickness d2 of the intermediate portion 223, and the support portion 101 is clamped between the first disk 221 and the second disk 222.
[0051] When the support wheel 22 is placed on the first groove 104, the support portion 101 is located between the first disk 221 and the second disk 222, which is beneficial to the stability of the support wheel 22 and prevents the support wheel 22 from falling off the support portion 101. Preferably, the thickness d1 of the support portion 101 is equal to the thickness d2 of the middle portion 223, so that the support portion 101 is just engaged between the first disk 221 and the second disk 222.
[0052] Continue to refer to Figure 1 and Figure 2 A second groove 107 is provided on the avoidance part 103 along the first direction X, and the top of the second groove 107 is connected to the bottom opening 106 of the first groove 104.
[0053] refer to Figure 6 In this embodiment, the second groove 107 is used to avoid the second slide bar 11, and the end of the second slide bar 11 passes through the second groove 107 along the third direction Z.
[0054] The transfer roller assembly 10 is a component that originally existed inside the developer. The two ends of the second slide bar 11 are fixedly connected to the housing of the developer. In order to add a pressure roller assembly 20 above the transfer roller assembly 10 without modifying the structure of the developer itself or affecting the original components inside the developer, a second groove 107 is provided on the avoidance part 103 of the bracket 100. The second groove 107 allows the second slide bar 11 to pass through, thus avoiding interference with the structure and components of the developer itself.
[0055] In this embodiment, in the first direction X, the center line of the first groove 104 and the center line of the second groove 107 are on the same straight line.
[0056] Because during glass transfer, the pressing roller 23 on the upper surface of the glass 30 to be transferred and the transfer roller 12 on the lower surface are aligned with each other, that is, the centers of the pressing roller 23 and the transfer roller 12 are on the same straight line (please refer to...). Figure 5 The pressing wheel 23 and the support wheel 22 are coaxially mounted on the first slide rod 21, the transmission roller 12 is mounted on the second slide rod 11, the support wheel 22 is placed on the first groove 104, and the second slide rod 11 passes through the second groove 107. Therefore, the center line of the first groove 104 and the center line of the second groove 107 are on the same straight line. This ensures that the center of the pressing wheel 23 and the center of the transmission roller 12 are on the same straight line after installation, so that the glass 30 to be transmitted is under stable force and is not damaged during transportation.
[0057] Continue to refer to Figure 1 and Figure 2 The connecting part 102 is provided with a mounting hole 108 and a mounting bolt 109. The mounting hole 108 is connected to the housing through the mounting bolt 109. The width d3 of the mounting hole 108 in the second direction Y is greater than the diameter of the mounting bolt 109, so that the connecting part 102 is suitable for adjusting the installation position in the second direction Y.
[0058] As mentioned above, aligning the pressing roller 22 with the transmission roller 12 during glass transfer is beneficial for balancing the force on the glass. If the pressing roller 22 and the transmission roller 12 are not aligned during the installation of the bracket 100 and the pressing roller assembly 20, the position of the bracket 100 can be adjusted appropriately in the second direction Y until the pressing roller 22 and the transmission roller 12 are aligned.
[0059] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
