Description

Technical Field

[0001] This utility model relates to the field of rubber ring installation technology, specifically to a rubber ring pressing mechanism and packaging processing equipment. Background Technology

[0002] Sealing rings are a common type of component, widely used in water supply and drainage, piping systems, automobiles, various machinery, household appliances, and electronic equipment.

[0003] Existing sealing ring pressing mechanisms can be found in patent application number CN201811222168.1. These mechanisms use a transmission gear and rack to transmit the rotational force of the operating handle to the rack. The rack moves left and right, transferring force in the lateral direction to the rubber ring for pressing. However, the rubber ring is prone to slight deflection during the pressing process, affecting the pressing quality.

[0004] Therefore, how to prevent the rubber ring from deflecting during the pressing process is a technical problem that urgently needs to be solved. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a rubber ring pressing mechanism and packaging processing equipment to solve the technical problem of how to avoid the rubber ring from deflecting during the pressing process in the prior art.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: In a first aspect, this utility model provides a rubber ring pressing mechanism, which includes: A guide member, wherein the guide member has a guide portion and a support portion at both ends, and the outer periphery of the support portion forms a fitting surface for fitting a rubber ring; A connector, mounted on the guide portion, having a first state of connecting the workpiece to secure the guide and the workpiece, and a second state of disengaging from the workpiece to allow the guide to detach from the workpiece; and The pressing component has a guide groove and a pressing groove that are interconnected. The guide part is movably inserted through the guide groove, and the outer periphery of the support part is attached to the inner wall of the pressing groove. By sliding the pressing component, the end of the pressing component pushes the rubber ring closer to the workpiece.

[0007] In some embodiments, the guide has a positioning hole, and the connector includes a positioning shaft and a snap-fit ​​part. The positioning shaft passes through the positioning hole, and the snap-fit ​​part is installed on the top end of the positioning shaft to prevent the positioning shaft from disengaging from the positioning hole. By allowing the positioning shaft to pass through or disengage from the pivot hole of the housing, the connector can switch between the first state and the second state.

[0008] In some embodiments, the positioning shaft has a screw at its top end, and the locking portion includes a nut that is screwed onto the screw.

[0009] In some embodiments, the top end of the guide portion is provided with a first guide cone surface.

[0010] In some embodiments, a second guide cone surface is provided at the top of the support portion.

[0011] In some embodiments, a stepped surface is provided between the guide portion and the support portion, the stepped surface preventing the pressing member from moving further toward the housing.

[0012] In some embodiments, a pad is provided at the bottom end of the pressing member.

[0013] In some embodiments, the guide portion and the support portion are coaxially arranged.

[0014] In some embodiments, the bottom end of the guide member is provided with a slot, which fits against the top of the housing.

[0015] Secondly, this utility model also provides a packaging processing equipment, which is equipped with the above-mentioned rubber ring pressing mechanism.

[0016] Compared with the prior art, the rubber ring pressing mechanism provided by this utility model has the following advantages: First, place the guide component on the workpiece, then adjust the connector to its first position to secure the workpiece and guide component together. Next, place the rubber ring to be installed around the outer circumference of the support portion. Then, move the guide groove around the outer circumference of the guide portion, allowing the pressing component to slide relative to the guide component. Because the inner wall of the pressing groove adheres to the outer circumference of the support portion, as the pressing component slides relative to the guide component, the end of the pressing component can push the rubber ring closer to the workpiece until the rubber ring is installed on the workpiece. During the process of the rubber ring approaching the workpiece, the support portion guides it, effectively preventing deflection and ensuring the quality of the rubber ring's installation.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] To address the technical problem of preventing the rubber ring B from deflecting during the pressing process, this invention provides a rubber ring B pressing mechanism. During the pressing process, the rubber ring B can be guided, thereby effectively preventing its deflection and ensuring the pressing quality of the rubber ring B.

[0021] It should be noted that the rubber ring B pressing mechanism of this utility model is used in, but not limited to, packaging and processing equipment. For ease of explanation, this utility model only uses the application of the rubber ring B pressing mechanism in packaging and processing equipment as an example. The principle of the rubber ring B pressing mechanism in other types of equipment is essentially the same as that in packaging and processing equipment, and will not be described in detail here.

[0022] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of the rubber ring B pressing mechanism in one embodiment of the present invention. The rubber ring B pressing mechanism includes a guide 100, a connector 200, and a pressing member 300. The guide 100 has a guide portion 110 and a support portion 120 at both ends, and the outer periphery of the support portion 120 forms a fitting surface for fitting the rubber ring B. The connector 200 is installed on the guide portion 110 and has a first state of connecting the workpiece A to fix the guide 100 and the workpiece A, and a second state of detaching from the workpiece A to allow the guide 100 to detach from the workpiece A. The pressing member 300 has a guide groove 310 and a pressing groove 320 that are interconnected. The guide portion 110 is movably inserted through the guide groove 310, and the outer periphery of the support portion 120 is attached to the inner wall of the pressing groove 320. By sliding the pressing member 300, the end of the pressing member 300 pushes the rubber ring B closer to the workpiece A.

[0023] In this embodiment, the guide member 100 is first placed on the workpiece, and then the connector 200 is adjusted to the first state, thereby fixing the workpiece and the guide member 100 together. Next, the rubber ring B to be installed is fitted onto the outer periphery of the support portion 120, and then the guide portion 110 is movably inserted into the guide groove 310, allowing the pressing member 300 to slide relative to the guide member 100. Since the inner wall of the pressing groove 320 is in contact with the outer periphery of the support portion 120, as the pressing member 300 slides relative to the guide member 100, the end of the pressing member 300 can push the rubber ring B closer to the workpiece until the rubber ring B is installed on the workpiece. During the process of the rubber ring B approaching the workpiece, the support portion 120 guides it, effectively preventing deflection and ensuring the pressing quality of the rubber ring B.

[0024] In some embodiments, the guide 100 has a positioning hole 130, and the connector 200 includes a positioning shaft 210 and a locking part 220. The positioning shaft 210 passes through the positioning hole 130, and the locking part 220 is mounted on the top end of the positioning shaft 210 to prevent the positioning shaft 210 from disengaging from the positioning hole 130. By allowing the positioning shaft 210 to pass through or disengage from the pivot hole of the housing A, the connector 200 can switch between a first state and a second state. When the positioning shaft 210 passes through the positioning hole 130 and the pivot hole of the housing A in sequence, the radial movement of the guide 100 relative to the housing A can be restricted. Although the guide 100 can still move axially relative to the housing A, the axial degree of freedom of the guide 100 does not affect the pressing of the rubber ring B. With the pressing of the pressing member 300, under the clamping pressure of the pressing member 300 and the housing A, the axial movement of the guide 100 can be prevented.

[0025] Any implementation of the snap-fit ​​part 220 that can fix the snap-fit ​​part 220 to the end of the positioning shaft 210 is feasible. In some embodiments, the top end of the positioning shaft 210 has a screw 211, and the snap-fit ​​part 220 includes a nut 221, which screws the screw 211.

[0026] In some embodiments, the top end of the guide portion 110 is provided with a first guide cone surface 111, which guides the guide portion 110 into the guide groove 310.

[0027] In some embodiments, the top of the support portion 120 is provided with a second guide cone surface 121. Guided by the second guide cone surface 121, it facilitates the worker to place the rubber ring B on the outer periphery of the support portion 120.

[0028] In some embodiments, a stepped surface 122 is provided between the guide portion 110 and the support portion 120, which prevents the pressing member 300 from continuing to move closer to the housing. This prevents the pressing member 300 from continuing to press the rubber ring B after it is installed on the housing A, thus preventing damage to the rubber ring B.

[0029] In some embodiments, a gasket 330 is provided at the bottom of the pressing member 300. The gasket 330 has a low hardness, which can protect the rubber ring B.

[0030] In some embodiments, the guide portion 110 and the support portion 120 are coaxially arranged.

[0031] In some embodiments, the bottom end of the guide member 100 is provided with a slot 140, which fits against the top of the housing A, so that the guide member 100 is more stably fixed to the housing A.

[0032] This utility model also provides a packaging and processing equipment, which is equipped with the above-mentioned rubber ring B pressing mechanism.

[0033] To better understand this utility model, the following is combined with... Figures 1 to 2 The technical solution of this utility model is described in detail below: First, the guide member 100 is placed on the workpiece, and the slot is aligned with the top of the housing A. Then, the positioning shaft 210 passes through the positioning hole 130 and the rotating shaft hole of the housing A in sequence, thereby restricting the radial movement of the guide member 100 relative to the housing A. Next, the rubber ring B to be installed is fitted onto the outer periphery of the support portion 120. Then, the guide portion 110 is movably inserted into the guide groove 310, allowing the pressing member 300 to slide relative to the guide member 100. Since the inner wall of the pressing groove 320 is aligned with the outer periphery of the support portion 120, as the pressing member 300 slides relative to the guide member 100, the end of the pressing member 300 can push the rubber ring B closer to the workpiece until the rubber ring B is installed on the workpiece. During the process of approaching the workpiece, the rubber ring B is guided by the support portion 120, effectively preventing deflection and ensuring the pressing quality of the rubber ring B.
