Description

Technical Field

[0001] This utility model relates to pre-press and post-press equipment, specifically a clutch mechanism for rubber rollers. Background Technology

[0002] Existing pre- and post-press equipment is equipped with a rubber roller and a steel spike wheel. The steel spike wheel located below the rubber roller has spike-like protrusions on its surface. During the paper feeding process, the spike-like structure on the surface of the steel spike wheel can easily embed paper fibers or debris when it comes into contact with the paper (especially when processing rough paper or corrugated paper). Long-term accumulation will cause the spike wheel surface to become blunt, reduce friction, and cause slippage or unstable paper feeding.

[0003] Meanwhile, in pre-press and post-press equipment and laminating equipment, steel barbs may come into contact with undried ink or glue. The residue hardens and blocks the gap between the barbs, causing paper gripping failure.

[0004] Accumulated paper scraps may get stuck between the barbs of the steel barb wheel, preventing the paper from passing through smoothly or even scratching the paper surface; if the barb wheel is covered with paper scraps, it may not be able to effectively separate the top layer of paper during paper separation, resulting in multiple sheets being fed into the equipment at the same time.

[0005] Therefore, the steel spike wheel needs to be cleaned regularly during use. However, under normal conditions, the rubber roller is in contact with the steel spike wheel, making it difficult to clean the steel spike wheel, and cleaning the rubber roller is also relatively difficult. To address this, a clutch mechanism for the rubber roller is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a clutch mechanism for rubber rollers to solve the above problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a clutch mechanism for a rubber roller, comprising a wall plate, a rubber roller movably mounted on the wall plate, and a lower roller equipped with a steel spike wheel and located below the rubber roller. The wall plate is provided with a slot for adjusting the up-and-down movement of the rubber roller. The mechanism is characterized by further including a clutch actuating element movably mounted on the wall plate for driving the rubber roller upwards and increasing the gap between the rubber roller and the steel spike wheel. The clutch actuating element is provided with at least one support platform that supports and limits the position of the rubber roller after it moves upwards.

[0008] A further preferred embodiment includes a guide surface disposed on the clutch actuator at the side of the support platform to guide the rubber roller as it moves onto the support platform.

[0009] A further preferred embodiment includes at least two support guides mounted on the wall panel to support the position of the clutch actuator on the wall panel and to guide the clutch actuator when it moves.

[0010] A further preferred embodiment includes a waist-shaped groove disposed on the clutch actuator and cooperating with the support guide to allow the clutch actuator to move based on the support guide.

[0011] A further preferred embodiment includes a positioning groove disposed on the support platform to limit the position of the rubber roller on the support platform.

[0012] A further preferred embodiment includes an actuating block disposed on the clutch actuating component to facilitate driving the clutch actuating component to move.

[0013] A further preferred embodiment includes a sheath mounted on the toggle block.

[0014] A further preferred embodiment includes a bearing mounted at the end of the rubber roller.

[0015] A further preferred embodiment includes a through hole provided on the clutch actuator for the rubber roller to pass through, the diameter of which is larger than the diameter of the rubber roller.

[0016] The beneficial effects of this utility model are as follows: With the setting of this device, when it is necessary to clean the rubber roller and the steel spike wheel, the rubber roller is driven to move upward by pushing the clutch actuating part and the position after it is raised is limited, thereby separating the rubber roller and the steel spike wheel, which facilitates the cleaning work of the rubber roller and the steel spike wheel.

[0022] The clutch mechanism for a rubber roller described in this utility model will be further explained below with reference to the accompanying drawings.

[0023] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly; for example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can also mean a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] See Figures 1-4 As shown, it includes a rubber roller 1, a lower roller 10, a steel spike wheel 2 mounted on the lower roller 10, and a wall plate 3 for movably mounting the rubber roller 1 and the lower roller 10. The wall plate 3 is provided with a slot 31 for adjusting the up and down movement of the rubber roller 1. It is characterized by further including a clutch actuating member 4 movably mounted on the wall plate 3 for driving the rubber roller 1 to move upward so that the rubber roller 1 is separated from the steel spike wheel 2, which facilitates the processing of the steel spike wheel 2 and the rubber roller 1. The clutch actuating member 4 is provided with at least one support platform 5 that supports and limits the position of the rubber roller 1 after it moves upward.

[0026] With the setup of this device, when it is necessary to clean the rubber roller 1 and the steel spike wheel 2, the rubber roller 1 is moved upward to the support platform 5 by pushing the clutch actuating part 4. The support platform 5 supports the rubber roller 1 and limits its position after being raised, thereby separating the rubber roller 1 and the steel spike wheel 2, which facilitates the cleaning of the rubber roller 1 and the steel spike wheel 2.

[0027] By setting the slot 31, the rubber roller 1 can be adjusted and moved up and down, avoiding interference from the wall panel 3 on the up and down movement of the rubber roller 1.

[0028] When the clutch actuator 4 is pushed, the clutch actuator 4 exerts a forward thrust on the rubber roller 1. When the rubber roller 1 is subjected to the forward thrust, it rotates. During the rotation, the clutch actuator 4 continues to move forward, and the rubber roller 4 moves onto the support platform 5.

[0029] In one embodiment, a guide surface 51 is provided on the clutch actuator 4 on the side of the support platform 5 to guide the rubber roller 1 when it moves to the support platform 5. By providing the guide surface 51, when the clutch actuator 4 is moved, the rubber roller 1 moves along the guide surface 51 to the support platform 5, which guides and reduces the resistance of the rubber roller 1.

[0030] In one embodiment, it further includes at least two support guides 6 mounted on the wall panel 3 to support the position of the clutch actuator 4 on the wall panel 3 and to guide the clutch actuator 4 when it moves. The support guides 6 support the clutch actuator 4 when it is movably mounted on the wall panel 3 and to guide the clutch actuator 4 when it moves.

[0031] In one embodiment, the clutch actuator 4 is further provided with a waist-shaped groove 7 that cooperates with the support guide 6 to allow the clutch actuator 4 to move based on the support guide 6. The waist-shaped groove 7 allows the clutch actuator 4 to move on the wall panel 3 based on the support guide 6.

[0032] In one embodiment, the clutch lever 4 is further provided with a lever block 8 for driving the clutch lever 4 to move. The lever block 8 is provided to facilitate pushing or pulling the clutch lever 4.

[0033] In one embodiment, a sleeve 9 is also included on the toggle block 8. The sleeve 9 may be made of elastic silicone or elastic rubber, so that the operator can make flexible contact between his hand and the toggle block 8 when pushing or pulling it.

[0034] In one embodiment, a bearing 11 is also provided at the ends of the rubber roller 1 and the lower roller 10. The bearing 11 allows the clutch actuator 4 to contact the rubber roller 1 through the bearing 11 or directly contact the rubber roller 1.

[0035] In one embodiment, a positioning groove 52 is provided on the support platform 5 to limit the position of the rubber roller 1 on the support platform 5. The positioning groove can be set as an arc groove or a rectangular groove or any other type. The positioning groove 52 limits the position of the rubber roller 1 on the support platform 5.

[0036] Further preferably, it also includes a through hole 41 provided on the clutch actuator 4 for the rubber roller 1 to pass through. The diameter of the through hole 4 is larger than the diameter of the rubber roller 1. The diameter of the through hole 41 is larger than the diameter of the rubber roller 1 so that the rubber roller 1 can move up and down.

[0037] When using this utility model: when it is necessary to clean the rubber roller 1 or the steel spike wheel 2, the operator pushes the actuating block 8 forward. The actuating block 8 drives the clutch actuating component 4 to move forward. The clutch actuating component 4 drives the waist-shaped groove 7 to move forward based on the support guide component 6. During the forward movement, the clutch actuating component 4 contacts the rubber roller 1 or the bearing 11 on the rubber roller 1 on the guide surface 51 and pushes the rubber roller 1 or the bearing 11 to move along the guide surface 51 to the support platform 5, thus completing the lifting of the rubber roller 1. At this time, the rubber roller 1 and the steel spike wheel 2 can be cleaned.

[0038] After cleaning is completed, the operator pulls the actuating block 8 backward. The actuating block 8 drives the clutch actuating component 4 to reset backward. During the reset process, the rubber roller 1 or bearing 11 moves off the support platform 5 and resets downward along the guide surface 51.

[0039] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
