Description

Technical Field

[0001] This utility model relates to the field of capping equipment, and in particular to a capping machine for laboratory use. Background Technology

[0002] In the research and development of beverage bottles and glass bottles, it is necessary to test the torque of the bottle caps to ensure that the liquid inside the bottle will not leak during transportation. Before conducting the torque test, a capping machine is used to screw the caps on, and then a bottle cap torque tester is used to measure the torque of the caps. However, current capping machines cannot adjust the height of the placement rack, so they can only cap bottles of the same height. When capping bottles of different sizes, workers need to hold the bottles by hand to seal them, and then use a bottle cap torque tester to measure the torque, which reduces the efficiency of torque testing.

[0003] CN202223258543 discloses a rotary can sealing machine, including a frame, a sealing assembly, and a lifting platform. A gear base and a motor base are fixedly mounted on the upper side of the frame. A sealing shaft and a transmission shaft are rotatably mounted on the gear base. Helical gears are fixedly mounted on the outer sides of both the sealing shaft and the transmission shaft, and these helical gears mesh with each other. A motor is fixedly mounted inside the motor base, driving the transmission shaft to rotate. A rotating shaft is rotatably mounted on the bottom side of the frame. A reducer is fitted between the lower end of the transmission shaft and the rotating shaft, and the reducer is detachably mounted inside the frame. A lifting cam is fixedly mounted on the outer side of the rotating shaft. A positioning cylinder is formed on the bottom side of the frame. The lower end of the lifting platform is inserted into the positioning cylinder with a clearance fit, and the lower end of the lifting platform presses against the outer side of the lifting cam. The lower end of the sealing shaft is fixedly connected to the sealing assembly. The lifting platform of this capping machine is driven by a cam, and the lifting height is the same each time. It cannot be well adapted to bottles of different heights, which affects its versatility.

[0004] The technical problem this invention aims to solve is: how to enable the capping machine to cap bottles of different heights, thereby improving its versatility. Summary of the Invention

[0005] The main purpose of this invention is to provide a capping machine for laboratory use. By setting a sliding placement plate on the placement rack and adjusting the height of the placement plate by an adjustment module, the top of the bottle can be kept at the same height as the capping unit when the bottle is placed on the placement plate. This allows the capping unit to screw on the caps of bottles of different heights with the same force, thus meeting the testing requirements.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

The lifting unit is provided with a placement frame. The placement frame is provided with an adjustment module and a placement plate for placing bottles. The placement plate is slidably connected to the placement frame. The adjustment module is used to adjust the height of the placement plate on the placement frame.

[0010] Preferably, the second fixing plate is provided with a detachable support block; the support block is provided with a second notch; the support block is provided with protrusions arranged in a circumferential array; the protrusions are used to support the bottle mouth.

[0011] Preferably, the placement plate is provided with a clamping module for clamping the bottle body.

[0012] Preferably, the clamping module includes a drive assembly and clamping blocks symmetrically arranged on the placement plate; the clamping blocks are slidably connected to the placement frame; the drive assembly is used to drive the symmetrically arranged clamping blocks to move closer to or further away from each other.

[0017] The capping machine in this case, by setting a sliding placement plate on the placement rack and adjusting the height of the placement plate by an adjustment module, ensures that when the bottle is placed on the placement plate, the height between the top of the bottle and the capping unit is the same. This allows the capping unit to screw on the caps of bottles of different heights with the same force, ensuring that the experimental conditions of the bottles are the same and meeting the requirements of torque testing.

[0018] Secondly, a clamping module is also provided on the placement plate. The clamping module clamps the bottle to prevent the bottle from rotating with the capping unit, thus ensuring that the experimental conditions of the bottles are the same. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application implemented as described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Example 1

[0027] refer to Figure 1-5 An experimental capping machine includes a frame 1 and a lifting unit 2, a drive unit 3, and a capping unit 4 for tightening bottle caps connected to the frame 1. The lifting unit 2 is provided with a placement rack 5. The placement rack 5 is provided with an adjustment module 6 and a placement plate 51 for placing bottles. The placement plate 51 is slidably connected to the placement rack 5. The adjustment module 6 is used to adjust the height of the placement plate 51 on the placement rack 5. The drive unit 3 is used to drive the capping unit 4 to rotate. The lifting unit 2 is used to drive the bottles on the placement plate 51 to contact or separate from the capping unit 4.

[0028] In this embodiment, the capping machine is used in the capping process before the cap torque test. The capping machine is used to perform the same operation on bottles of different sizes, thereby ensuring that the external conditions are the same each time the cap is put on the bottle, thus ensuring the accuracy of the cap torque test.

[0029] The specific operation process of the capping machine is as follows: According to the height of the bottle, the operator adjusts the position of the placement plate 51 on the placement rack 5 through the adjustment module 6, so that the distance between the top of the bottle and the capping unit 4 is kept in a suitable position so that the capping unit 4 can tighten the cap. After the adjustment is completed, the drive unit 3 drives the capping unit 4 to rotate, and the lifting unit 2 moves up and down to move back and forth, thereby driving the placement rack 5 and the bottle to the capping unit 4 for the capping operation. After the capping is completed, the placement rack 5 and the bottle are driven down, and the operator can remove the bottle and carry out the capping operation of the next bottle.

[0030] It should be noted that the drive unit 3 continuously drives the sealing unit 4 to rotate, and at the same time drives the lifting unit 2 to move up and down reciprocally.

[0031] The capping unit 4 is existing technology. For specific structure, please refer to the capping head body structure in CN201821434875 or commercially available capping structures that can achieve the capping function.

[0032] Preferably, the placement rack 5 is composed of a first fixing plate 52, a guide shaft 53, and a second fixing plate 54 connected from bottom to top; the first fixing plate 52 is connected to the lifting unit 2; the second fixing plate 54 is provided with a first notch 541 for the bottle mouth to pass through; the placement plate 51 is slidably connected to the placement rack 5 via the guide shaft 53.

[0033] In this embodiment, the bottom of the bottle is placed on the placement plate 51, and the bottle mouth is inserted into the notch to fix the bottle. In this way, the friction of the bottle can be increased, so that when the lifting unit 2 drives the bottle to rise to the capping unit 4 for capping, the bottle is prevented from rotating with the capping unit 4 and affecting the capping quality.

[0034] Preferably, the adjustment module 6 includes a lead screw 61, a first motor 62 for driving the lead screw 61 to rotate, and a nut 63; the two ends of the lead screw 61 are rotatably connected to a first fixing plate 52 and a second fixing plate 54 respectively; the first motor 62 is connected to the bottom of the first fixing plate 52; the nut 63 is slidably connected to the lead screw 61 and is connected to the placement plate 51.

[0035] In this embodiment, the specific operation process of the adjustment module 6 is as follows: the operator starts the first motor 62, the first motor 62 drives the lead screw 61 to rotate, thereby driving the nut 63 to move linearly on the lead screw 61, and then driving the placement plate 51 to move up and down, so as to realize the height adjustment of the placement plate 51.

[0036] Secondly, by setting the guide shaft 53, the placement plate 51 can move more smoothly during the process.

[0037] Preferably, the second fixing plate 54 is provided with a detachable support block 55; the support block 55 is provided with a second notch 551; the support block 55 is provided with protrusions 552 arranged in a circular array; the protrusions 552 are used to support the bottle mouth.

[0038] In this embodiment, since the cap torque test requires sealing different types and sizes of bottles, including varying heights and opening sizes, a detachable support is provided. This allows for the fabrication of multiple supports for the second notch 551 with different specifications, thereby accommodating bottles of different sizes. Furthermore, a circular array of protrusions 552 is arranged along the edge of the second notch 551 to reduce the contact area between the bottle opening and the support, preventing scratches on the bottle opening.

[0039] Preferably, the placement plate 51 is provided with a clamping module 7 for clamping the bottle body.

[0040] In this embodiment, the bottle is clamped by a clamping module 7 on the placement plate 51 to prevent the bottle from shaking or shifting during the lifting process, ensuring that the bottle is in the center position of the placement plate 51 so as to perform the capping operation and improve the capping quality.

[0041] Preferably, the clamping module 7 includes a driving component 72 and clamping blocks 71 symmetrically arranged on the placement plate 51; the clamping blocks 71 are slidably connected to the placement frame 5; the driving component 72 is used to drive the symmetrically arranged clamping blocks 71 to move closer to or further away from each other.

[0042] In this embodiment, after the bottle is placed on the placement plate 51, the drive assembly 72 moves the clamping blocks 71 closer together to clamp the bottle and position it at the center of the placement plate 51. After the capping is completed, the drive assembly 72 moves the clamping blocks 71 away from each other, thereby releasing the bottle so that the operator can replace it with the next bottle for the capping operation.

[0043] The drive assembly 72 is a wide-type finger cylinder, and the appropriate model can be selected according to actual needs.

[0044] Preferably, the lifting unit 2 includes a lifting rod 21, a fixed rod 22, and a rotating rod 23; the lifting rod 21 is slidably connected to the frame 1; the fixed rod 22 is connected to the frame 1; the end of the fixed rod 22 is rotatably connected to the rotating rod 23; the fixed rod 22 is provided with a rotatable first gear 24; the bottom of the first gear 24 is provided with a cam 25; one end of the rotating rod 23 is rotatably connected to the lifting rod 21, and the other end is slidably connected to the cam 25.

[0045] In this embodiment, one side of the cam 25 is a protrusion 251, and the other side is a flat portion 252. The specific movement process of the lifting unit 2 is as follows: the drive unit 3 drives the first gear 24 to rotate and drives the cam 25 to rotate. As the end of the rotating rod 23 gradually changes from contact with the flat portion 252 of the cam 25 to contact with the protrusion 251, one end of the rotating plate is subjected to the pressure of the cam 25 and rotates downward, while the other end drives the lifting rod 21 to move upward, thereby driving the placement rack 5 and the bottle to move towards the capping unit 4. As the end of the rotating rod 23 gradually changes from contact with the protrusion 251 of the cam 25 to contact with the flat portion 252, due to the gravity of the placement rack 5, the end of the rotating rod 23 in contact with the lifting rod 21 rotates downward, causing the bottle to move away from the capping unit 4. The other end of the rotating rod 23 will remain in contact with the cam 25 and gradually rotate upward, similar to the principle of a "seesaw".

[0046] Preferably, the end of the rotating rod 23 is provided with a roller 231; the rotating rod 23 contacts the cam 25 through the roller 231.

[0047] In this embodiment, the rotating rod 23 contacts the cam 25 through the roller 231, thereby changing the sliding connection between the rotating rod 23 and the cam 25 into a rolling connection, reducing wear between the rotating rod 23 and the cam 25, and improving the service life of the rotating rod 23 and the cam 25.

[0048] Preferably, the drive unit 3 includes a second motor 31, a transmission rod 32, a first belt 33, and a second belt 34; the second motor 31 is connected to the frame 1; the transmission rod 32 is rotatably connected to the frame 1; the second motor 31 drives the sealing unit 4 to rotate via the first belt 33; the sealing unit 4 drives the transmission rod 32 to rotate via the second belt 34; the end of the transmission rod 32 is provided with a second gear 321; the second gear 321 meshes with the first gear 24.

[0049] In this embodiment, both the second motor 31 and the transmission rod 32 are equipped with a pulley, and the sealing unit 4 has two pulleys. The sealing unit 4 is connected to the second motor 31 via a first belt 33. The diameter of the pulley on the sealing unit 4 is smaller than that of the pulley on the second motor 31, allowing the second motor 31 to drive the sealing unit 4 to rotate quickly at a lower speed. The sealing unit 4 is connected to the transmission via a second belt 34. The diameter of the pulley on the sealing unit 4 is smaller than that of the pulley on the transmission rod 32, thus reducing the rotational speed of the transmission rod 32. When the transmission rod 32 rotates, it drives the second gear 321 to rotate, which in turn drives the first gear 24 to rotate. By setting an appropriate pulley diameter, the sealing unit 4 can rotate quickly, and the lifting unit 2 can reciprocate up and down at a suitable speed.
