Description

Technical Field

[0001] This utility model relates to the field of glove production equipment technology, specifically a hand mold track adjustment mechanism. Background Technology

[0002] In glove production lines, hand molds often need to be conveyed to reach the required workstations or processes. Existing technologies typically use conveyor belts or conveyor chains for this purpose. For example, patent CN214163737U discloses an automatic demolding device for a glove production line, including a frame, guide rails, a conveyor chain, and hand molds, with the hand molds conveyed along the guide rails via the conveyor chain. While this method achieves automated conveying, it has limitations in practical applications. Specifically, during conveying, the hand molds do not automatically change tracks; that is, several hand molds arranged on a conveyor belt or chain will move uniformly along the same unchanging track from the moment they are conveyed to their destination. Therefore, it is impossible to automatically distinguish or redirect the hand molds during the conveying process, which can lead to several negative consequences, such as:

[0003] In production lines, hand molds that require cleaning are typically cleaned during transport. To improve efficiency, brush machines usually have a large brushing range. However, when only a single hand mold needs cleaning, the brush cannot automatically distinguish between different molds during transport. As a result, the brush may simultaneously brush other hand molds located in front of and behind the first one that do not require cleaning. This negatively impacts the lifespan of both the hand mold and the brush. Furthermore, because automatic steering of the hand molds during transport is not possible, switching batches of hand molds to non-coated or coated tracks according to production requirements necessitates slowing down or pausing the production line and then manually completing the operation. This requires significant manpower and resources and poses safety hazards.

[0004] In summary, this utility model provides a hand mold track adjustment mechanism. Utility Model Content

[0005] The purpose of this utility model is to provide a hand mold track adjustment mechanism to solve the problem mentioned in the background art, where the existing technology cannot automatically change the track of the hand mold during transport, which causes a variety of adverse effects.

[0006] This utility model is achieved using the following technical solution:

[0007] A hand mold track adjustment mechanism includes a frame, on which a drive part and a lifting part are provided; the lifting part includes a lifting arm array, which is composed of a plurality of lifting arms, which can be arranged under the action of the drive part to form a slope through which the hand mold passes.

[0008] In this technical solution, the drive unit is used to drive the lifting unit to move. The lifting unit is used to change the hand mold from the current track to another track. Specifically, when the hand mold that needs to change tracks moves along the current track to the position of the lifting unit, several lifting arms will sequentially rotate and shift around the lifting rotation axis at different amplitudes. That is, several lifting arms will lift up one by one and the lifting degree will gradually increase. Based on this, a slope can be built for the hand mold to pass through. The hand mold can reach the upper track through the slope, thereby completing the track change adjustment.

[0009] Furthermore, the driving part includes a cam group, which comprises several cams arranged and connected to the driving rotation shaft, each cam having a different stroke range. Each cam drives a different lifting arm, and because the stroke ranges of the cams are different, the lifting arms can sequentially perform rotational displacement movements of different amplitudes.

[0010] Furthermore, the drive unit includes several cylinders arranged side by side, with the piston rods of each cylinder contacting a corresponding lifting arm. By controlling the piston rods of each cylinder to extend and retract to different degrees, the lifting arms can sequentially perform rotational displacement movements of different amplitudes.

[0011] Furthermore, each cam contacts the corresponding lifting arm to form several contact points. When the cam stroke is at its maximum, the distance between the several contact points and the axis of the drive rotating shaft increases or decreases sequentially.

[0012] Furthermore, the lifting arm includes a transmission part and a lifting part connected together, the transmission part slidingly contacts the wheel surface of the cam, and a lifting rotation shaft passes through between the transmission part and the lifting part.

[0013] Furthermore, several cams in the cam group are arranged and connected to the drive rotating shaft along the track running direction, and several lifting arms are arranged and connected to the lifting rotating shaft along the track running direction.

[0014] Furthermore, one end of the drive shaft is connected to a rotary power device. The rotary power device is connected to an external power mechanism and can drive the drive shaft to rotate, thereby driving the cam to rotate.

[0015] Furthermore, the frame includes two opposing vertical fixed plates, and the lifting rotation shaft and the drive rotation shaft are mounted between the two fixed plates.

[0016] Furthermore, the cam travel range of the plurality of cams gradually increases or gradually decreases in sequence.

[0017] Furthermore, the transmission part and the lifting part adopt a plate-like structure or a rod-like structure.

[0018] The beneficial effects achieved by this utility model are:

[0019] A hand mold track-changing adjustment mechanism, by setting up a drive section and a lifting section, and by setting up several lifting arms in the lifting section to perform sequential rotational displacement movements of different amplitudes, can construct an ascending track in the form of a dynamic staircase. Based on this, the hand mold can be changed from the current track to another track. Compared with the prior art, by setting this mechanism on a conveyor belt or conveyor chain equipment, automatic track switching of the hand mold can be realized, thereby enabling automatic differentiation and turning of the hand mold during the conveying process. This can avoid many negative impacts, such as damage to the brush machine and hand mold life, high consumption of manpower and material resources, and potential safety hazards in production.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Example 1

[0028] Please refer to Figures 1 to 5This embodiment provides a hand mold track adjustment mechanism, including a frame, on which a drive part and a lifting part are provided, specifically:

[0029] The frame includes a base plate and two opposing vertical fixed plates 2, with a drive unit and a lifting unit installed between the two fixed plates 2.

[0030] The lifting section includes a lifting arm array, which consists of several lifting arms 1 arranged along the track running direction and connected to the lifting rotation shaft 4. In this embodiment, the driving section includes a cam group (in other embodiments, the driving section may include several cylinders arranged side by side, with the piston rods of the cylinders respectively contacting the corresponding lifting arms 1), and the cam group includes several cams 5 arranged along the track running direction and connected to the driving rotation shaft 6; one end of the driving rotation shaft 6 passes through the fixed plate 2 and is connected to the rotation power device 3. In this embodiment, the rotation power device 3 specifically adopts a rotating pulley, which is connected to an external power mechanism (in practical applications, those skilled in the art can also specifically select structures such as motors, transmission belts (in conjunction with external power mechanisms) according to the actual situation, and this utility model does not make any special limitations in this regard); wherein, to achieve a high degree of automation, an intelligent controller can be used to control the action of the external power mechanism.

[0031] Each cam 5 in the cam group contacts the corresponding lifting arm 1 to form several contact points. When the cam stroke is at its minimum, all contact points are on the same plane. When the cam stroke is at its maximum, the distance between the contact points and the axis of the drive rotating shaft 6 increases or decreases sequentially. Under the drive of the corresponding cam 5, the lifting arms 1 form an inclined structure that gradually rises or falls sequentially, thus forming the slope through which the hand mold passes. The cam stroke range of the several cams 5 arranged along the track running direction gradually increases (the cam stroke range refers to the maximum displacement distance of the cam follower during the movement process; in practical applications, the shape and stroke value of several cams 5 can be specifically selected according to the actual situation, and this utility model does not make any special limitations in this regard).

[0032] The lifting arm 1 includes a transmission part 1-2 and a lifting part 1-1 connected to each other. In this embodiment, there is an included angle between the transmission part 1-2 and the lifting part 1-1. Both the transmission part 1-2 and the lifting part 1-1 are long and narrow plate shapes (in other embodiments, the shape type and parameters can be adjusted according to the actual situation, and this utility model does not make any special limitation in this regard); the transmission part 1-2 slides in contact with the wheel surface of the cam 5, and a lifting rotation shaft 4 passes through between the transmission part 1-2 and the lifting part 1-1.

[0033] Based on the above structure, the working principle of this embodiment is as follows:

[0034] When this mechanism is placed in a suitable position on a conveyor belt or conveyor chain, it will not obstruct other hand molds that do not require track changes after the mechanism is not working or track adjustment is achieved (this can be achieved by setting the height of the mechanism to be equal to or lower than the height of the track where other hand molds are located, etc. The method can be set by those skilled in the art according to the actual situation, and this utility model does not make any special limitation in this regard).

[0035] When the hand mold that needs to change tracks moves along the current track to the lifting section position, specifically, the rotational power device 3 of the rotating pulley will rotate under the drive of the external power mechanism, thereby driving the drive rotating shaft 6 to rotate, which in turn causes several cams 5 in the cam group to rotate. At this time, several lifting arms 1 will sequentially perform rotational displacement movements of different amplitudes around the lifting rotating shaft 4, that is, please refer to Figure 2 Several lifting arms 1 will lift upwards one by one, with the lifting degree gradually increasing. Based on this, the lifting arms 1 can be arranged to form a ramp for the hand mold to pass through, allowing the hand mold to reach the upper track. After the hand mold passes through the lifting section, as the cam assembly continues to rotate, the lifting arms 1 will continue to perform rotational displacement motion, as described in the following figure. Figure 3 Several lifting arms 1 will descend to their initial positions, where they are horizontally aligned and will not obstruct other hand molds that do not require track changes.

[0036] Based on this, the hand mold track adjustment mechanism provided in this embodiment can realize automatic track switching of the hand mold, thereby enabling automatic differentiation and turning of the hand mold during the conveying process, thus avoiding many negative impacts, such as wear and tear on the brush machine and hand mold, excessive manpower and material resources, and potential safety hazards.

[0037] It should be noted that the parts not described in detail or in an elaborate manner in the above solution are all existing technologies or conventional / adaptive settings by those skilled in the art, and do not constitute improvements made by this utility model to existing technologies, nor are they within the protection scope of this utility model's technical solution. Therefore, they will not be elaborated upon in this article.

[0038] Of course, the above description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of the embodiments of this utility model. This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
