Description

Technical Field

[0001] The utility model relates to the field of food and medicine packaging machinery, in particular to a pump cover tightening device. Background Art

[0002] For conventional cylindrical bottle caps, the capping process is generally that the capping mechanism descends to grab the bottle cap during the revolution, then rotates to tighten the bottle cap, and finally loosens the bottle cap and rises to reset. In order to prevent the bottle cap from being damaged or over-tightened due to excessive torque, a torque limiter is generally set on the input side of the gripper. Figure 1 The pump cap is different from the conventional bottle cap, and includes a pump cap body, a spray tube located on the side of the pump cap body, and a straw located under the pump cap body. Figure 2 When the pump caps are sorted into rows by the cap sorting bucket, the direction of the nozzle is random, which makes it easy for the clamp to damage the nozzle when grabbing the pump cap, and it is not conducive to tightening the pump cap reliably when grabbing the nozzle. In addition, when the size of the straw is long, it is easy to deform, resulting in failure to accurately insert into the bottle body. These factors greatly increase the difficulty of tightening the pump cap and production efficiency.

[0003] The existing production equipment for oral sprays, nasal sprays, external sprays and other products with pump covers includes several types: 1. Intermittent equipment, the speed is generally low, about 60pcs (60 products per minute); 2. After the pump cover is screwed, an additional station is added to install the nozzle (or it can be installed manually), the speed is generally below 120pcs; 3. After the pump cover is screwed, the nozzle and spray are packaged separately, and the user assembles them by himself when using it, the speed is generally below 120pcs, and it brings inconvenience to the user. At present, there is a lack of high-speed pump cover screwing solutions that can complete assembly in one go on the market. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a pump cover tightening device which has a simple structure, good reliability and is conducive to relatively fixing the direction of the pump cover for subsequent grasping and tightening.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A pump cover tightening device comprises a cover screwing mechanism and a pump cover arrangement component, a pump cover conveying track and a cover-moving turntable which are connected in sequence. The outer periphery of the cover-moving turntable is provided with a plurality of first cover-moving parts and the side is provided with a protective fence. The pump cover tightening device also comprises a directional disk, the directional disk coincides with the center line of the cover-moving turntable, the outer periphery of the directional disk is provided with a plurality of second cover-moving parts for moving the nozzle on the pump cover, and the first cover-moving parts and the second cover-moving parts are alternately distributed along the circumferential direction.

[0007] As a further improvement of the above technical solution: a jaw orienting member is provided upstream of the cap taking station of the cap screwing mechanism. The cap screwing mechanism includes a cap screwing jaw, a rotating member for driving the cap screwing jaw to rotate, and a clutch connected between the rotating member and the cap screwing jaw. A disengaging member for cooperating with the jaw orienting member to separate the cap screwing jaw from the rotating member is provided on the cap screwing jaw.

[0008] As a further improvement of the above technical solution: the jaw orienting member is an arc-shaped guide block.

[0009] As a further improvement of the above technical solution: the clutch is a torque limiter.

[0010] As a further improvement of the above technical solution: the disengaging member is a roller or a rolling bearing.

[0011] As a further improvement of the above technical solution: a guiding jaw is further provided below the cap screwing jaw. When the guiding jaws are closed, a guiding channel for the straw of the pump cap to pass through is formed.

[0012] As a further improvement of the above technical solution: the orienting disk is located above the cap dialing turntable.

[0013] As a further improvement of the above technical solution: a plurality of weight-reducing through holes are provided on the orienting disk.

[0014] Compared with the prior art, the advantages of the present utility model are as follows:

[0015] The pump cap screwing device disclosed by the present utility model sorts the pump cap components into columns and conveys them to the cap dialing turntable through the pump cap conveying track. After the pump cap enters the cap dialing turntable, the pump cap is dialed away by the first cap dialing part. During the rotation, the nozzle of the next pump cap will be dialed to the front or rear position by the second cap dialing part on the orienting disk, and the pump cap with the nozzle already located on the front or rear side of the pump cap body can smoothly pass through the gap between the second cap dialing part and the protective fence, thereby completing the orientation of the pump cap, facilitating the effective taking of the pump cap by the cap screwing mechanism, avoiding damaging the nozzle and effectively screwing the pump cap. The structure is simple and the reliability is good, providing a basis for efficiently completing the assembly of the pump cap at one time.

[0029] The present utility model will be further described in detail below in conjunction with the specification drawings and specific embodiments.

[0030] Figures 3 to 6 An embodiment of the pump cover tightening device of the present utility model is shown. The pump cover tightening device of this embodiment includes a cap screwing mechanism 6 and a pump cover arranging component 1 (such as a cover arranging hopper), a pump cover conveying track 2, and a cover dial 3 that are connected in sequence. A plurality of first cover dialing parts 31 are provided on the outer periphery of the cover dial 3, and a protective fence 4 is provided on the side. The pump cover tightening device further includes an orientation disk 5. The orientation disk 5 coincides with the center line of the cover dial 3. A plurality of second cover dialing parts 51 for dialing the spray pipe 102 on the pump cover are provided on the outer periphery of the orientation disk 5. The first cover dialing parts 31 and the second cover dialing parts 51 are alternately distributed in the circumferential direction.

[0031] In the pump cover tightening device of this embodiment, the pump cover arranging component 1 arranges the pump covers into columns and conveys them to the cover dial 3 through the pump cover conveying track 2. Specifically, refer to Figure 4 , after the pump cover enters the cover dial 3, the pump cover is dialed away by the first cover dialing part 31. During the rotation, the spray pipe 102 of the next pump cover will be dialed to the front or rear position by the second cover dialing part 51 on the orientation disk 5, and the pump cover with the spray pipe 102 already located on the front side or rear side of the pump cover body 101 can smoothly pass through the gap between the second cover dialing part 51 and the protective fence 4, thereby completing the orientation of the pump cover, facilitating the effective picking of the pump cover by the cap screwing mechanism 6, avoiding scratching the spray pipe 102, and effectively tightening the pump cover at the same time. The structure is simple and the reliability is good, providing a basis for efficiently completing the pump cover assembly at one time.

[0032] Furthermore, as shown in Figure 1 and Figure 2 , in this embodiment, a jaw orienting part 7 is provided upstream of the cap picking station of the cap screwing mechanism 6. The cap screwing mechanism 6 includes a cap screwing jaw 62, a rotating part 64 for driving the cap screwing jaw 62 to rotate, and a clutch 61 connected between the rotating part 64 and the cap screwing jaw 62. A disengaging part 63 for cooperating with the jaw orienting part 7 to separate the cap screwing jaw 62 from the rotating part 64 is provided on the cap screwing jaw 62. Specifically, refer to Figure 6, before removing the next pump cover, the gripper orienting member 7 acts as a cam to apply a force to the disengaging member 63, separating the cap - screwing gripper 62 from the rotating member 64, ensuring that the angle between the cap - screwing gripper 62 and the pump cover on the cover - dialing turntable 3 is relatively fixed. Thus, it is ensured that the nozzle 102 will not be damaged when the cap - screwing gripper 62 grabs the pump cover, and at the same time, the pump cover is reliably screwed on, further improving the reliability of the device. After the disengaging member 63 is separated from the gripper positioning member 7, they cannot cooperate continuously. At this time, the cap - screwing gripper 62 coincides and combines with the rotating member 64, and the rotating member 64 can drive the cap - screwing gripper 62 to rotate through the clutch 61, thereby screwing the pump cover onto the bottle body.

[0033] As a preferred embodiment, the gripper orienting member 7 is an arc - shaped guide block 71, and the disengaging member 63 can contact or separate from the arc - shaped guide block 71 during rotation, with a simple and reliable structure.

[0034] As a preferred embodiment, the clutch 61 is a torque limiter. When the torque generated by the mutual cooperation between the disengaging member 63 and the arc - shaped guide block 71 exceeds a certain value, the torque limiter cannot transmit torque between the rotating member 64 and the cap - screwing gripper 62, that is, disengagement is achieved, with a simple structure and convenient use.

[0035] As a preferred embodiment, the disengaging member 63 can be a roller or a rolling bearing. Using a roller or a rolling bearing can reduce the frictional resistance between the disengaging member 63 and the arc - shaped guide block 71, making the rotation process smoother.

[0036] Further, in this embodiment, a guiding gripper 8 is also provided below the cap - screwing gripper 62. When the guiding gripper 8 closes, a guiding channel 81 for the straw 103 of the pump cover to pass through is formed. See specifically Figure 6 , when the length of the straw 103 is long and prone to deformation, the guiding gripper 8 closes to form the guiding channel 81, providing a guiding effect for the straw 103, so that the straw 103 can be accurately inserted into the bottle body below, with a simple and effective structure.

[0037] As a preferred embodiment, the orienting disk 5 is located above the cover - dialing turntable 3, with a simple structure, easy to disassemble, assemble and maintain.

[0038] Further, in this embodiment, a plurality of weight - reducing through - holes 52 are provided on the orienting disk 5, which can reduce the self - weight of the orienting disk 5. Preferably, the weight - reducing through - holes 52 are arc - shaped long holes.

[0039] Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present utility model by using the technical content disclosed above without departing from the scope of the technical solution of the present utility model, or modify it into an equivalent embodiment with equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model without departing from the content of the technical solution of the present utility model shall fall within the scope of protection of the technical solution of the present utility model.
