Description

Technical Field

[0001] This utility model particularly relates to a counterweight balancing brush adjustment device for a candy packaging machine. Background Technology

[0002] In the candy packaging production process, candies typically undergo conveying, arranging, and packaging. The candy-carrying turntable is used to arrange and convey the candies in an orderly manner to the packaging station, while the brush assembly is used to clean the candies on the turntable surface, ensuring accurate positioning and preventing jamming or misalignment.

[0003] Traditional brush height adjustment mechanisms lack dynamic balancing capabilities.

[0004] Existing technologies use fixed springs or rigid connection structures, which cannot adjust the brush pressure in real time according to changes in candy height, resulting in inconsistent cleaning effects on candies of different heights and affecting the stability of packaging quality.

[0005] Mechanical regulating devices suffer from response hysteresis.

[0006] Conventional counterweight structures are mostly fixed counterweights, which cannot achieve dynamic counterweight adjustment and are difficult to respond quickly to changes in candy height during high-speed packaging. Utility Model Content

[0007] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a counterweight balancing brush adjustment device for a candy packaging machine.

[0008] To solve the aforementioned technical problems, this utility model adopts the following technical solution:

[0009] A counterweight-balanced brush adjustment device for a candy packaging machine includes a frame with a rotatable candy-carrying turntable on the frame. The turntable has an array of candy-limiting holes on its surface. A brush assembly for cleaning candy is mounted on the frame, with the brush bristles positioned above the turntable. The brush assembly is connected to the frame via an elastic connecting component. A counterweight balancing mechanism is provided between the brush assembly and the frame. The counterweight balancing mechanism includes a screw connecting the brush assembly and the frame. A counterweight is connected to the middle section of the screw. When the counterweight moves along the screw towards the brush assembly, the weight of the counterweight causes the brush assembly to pull the elastic connecting component downwards. When the counterweight moves away from the brush assembly, the brush assembly returns to its original position and rises under the action of gravity and the elastic connecting component.

[0010] Preferably, the elastic connection assembly includes a left fixed rod disposed on the frame and a right fixed rod connected to the back of the brush assembly. An elastic ring is wound between the left and right fixed rods, and its axial length in its natural state is less than the initial distance between the two fixed rods. When the brush assembly is deflected downward by the counterweight, the right fixed rod moves downward with the brush assembly, forcing the elastic ring to stretch and deform to generate a restoring force. When the counterweight moves in the opposite direction, the restoring force of the elastic ring assists the brush assembly to reset and rise.

[0011] Preferably, the elastic ring is made of silicone rubber or polyurethane.

[0012] Preferably, the counterweight block has a counterweight cavity inside, and the cavity contains counterweight particles that can be added or removed.

[0013] Preferably, the counterweight particles are tungsten alloy spheres with a diameter of 3-5 mm.

[0014] Preferably, multiple counterweight particles are combined by magnetic adsorption.

[0015] The beneficial effects of this utility model are:

[0016] The counterweight-balanced brush adjustment device of this invention demonstrates significant multi-functional advantages in practical applications. By utilizing the movement of the counterweight along the screw, the device can flexibly adjust the pressure applied to the brush assembly for candies of different heights. This adjustment mechanism not only meets diverse cleaning needs but also ensures that, during the packaging process, both tall hard candies and short soft candies achieve the desired cleaning effect, effectively guaranteeing the stability of packaging quality.

[0017] The flexible structure of the elastic connection component acts as a "stabilizing assistant" for the device, playing a crucial role in the deflection and reset of the brush assembly. It endows the brush assembly with excellent reset capability, enabling it to quickly return to its initial position during frequent cleaning actions, maintaining consistent cleaning force.

[0026] A counterweight balancing brush adjustment device for a candy packaging machine, as described in the following figure. Figures 1-2The system includes a frame 1, on which a rotatable candy-carrying turntable 2 is mounted. The surface of the candy-carrying turntable 2 is provided with an array of candy-limiting holes 3. A brush assembly 4 for cleaning candy is mounted on the frame 1, with the bristles positioned above the candy-carrying turntable 2. The brush assembly 4 is connected to the frame 1 via an elastic connecting component 5. A counterweight balancing mechanism 6 is provided between the brush assembly 4 and the frame 1. The counterweight balancing mechanism 6 includes a screw 61 connected between the brush assembly 4 and the frame 1. A counterweight 62 is connected to the middle section of the screw 61. When the counterweight 62 moves towards the brush assembly 4 along the screw 61, the gravity of the counterweight 62 causes the brush assembly 4 to pull the elastic connecting component 5 downwards. When the counterweight 62 moves away from the brush assembly 4, the brush assembly 4 returns to its original position and rises under the action of gravity and the elastic connecting component 5.

[0027] Furthermore, the elastic connection assembly 5 includes a left fixing rod 51 mounted on the frame 1 and a right fixing rod 52 connected to the back of the brush assembly 4. An elastic ring 53 is wound between the left fixing rod 51 and the right fixing rod 52, and its axial length in its natural state is less than the initial distance between the two fixing rods. When the brush assembly 4 is deflected downward by the counterweight 62, the right fixing rod 52 moves downward with the brush assembly 4, forcing the elastic ring 53 to stretch and deform to generate a restoring force. When the counterweight 62 moves in the opposite direction, the restoring force of the elastic ring 53 assists the brush assembly 4 to reset and rise.

[0028] Furthermore, the material of the elastic ring 53 is silicone rubber or polyurethane.

[0029] Furthermore, the counterweight block 62 has a counterweight cavity 7 inside, and the cavity contains counterweight particles 8 that can be added or removed.

[0030] Furthermore, the counterweight particle 8 is a tungsten alloy sphere with a diameter of 3-5 mm.

[0031] Furthermore, multiple counterweight particles 8 form an assembly through magnetic adsorption.

[0032] The working principle of this utility model is as follows:

[0033] like Figure 1 As shown, a counterweight balancing brush adjustment device for a candy packaging machine includes a frame 1. A rotatable candy-carrying turntable 2 is mounted on the frame 1. The surface of the candy-carrying turntable 2 is provided with an array of candy-limiting holes 3 for carrying candies to be packaged and achieving orderly rotational conveying of the candies. A brush assembly 4 for cleaning the candies is mounted on the frame 1, with the bristle ends positioned above the candy-carrying turntable 2. The brush assembly 4 is connected to the frame 1 via an elastic connecting component 5.

[0034] A counterweight balancing mechanism 6 is provided between the brush assembly 4 and the frame 1. This mechanism includes a screw 61 and a counterweight 62. The screw 61 connects the brush assembly 4 and the frame 1, serving as a track and support for the movement of the counterweight 62. The counterweight 62 is located in the middle section of the screw 61, and its weight and position are adjustable. By changing the position of the counterweight 62, the pressure of the brush assembly 4 is adjusted to accommodate candies of different heights. When cleaning shorter candies, the counterweight 62 moves along the screw 61 towards the brush assembly 4. At this time, the gravity of the counterweight 62 acts on the brush assembly 4, causing it to pull the elastic connecting component 5 downwards at a certain angle. The elastic ring 53 is stretched, generating an elastic restoring force. After the brush assembly 4 deflects downwards, the bristle tips contact the surface of the shorter candy, applying appropriate pressure for cleaning and ensuring effective cleaning.

[0035] Conversely, when it is necessary to clean taller candies, the counterweight 62 is moved away from the brush assembly 4. At this time, the brush assembly 4 returns to its original position and rises under its own weight and the elastic restoring force of the elastic connecting component 5. The restoring force of the elastic ring 53 helps the brush assembly 4 return to its initial position, so that the bristles gently contact the surface of the taller candies, avoiding excessive pressure that could damage the candies, while ensuring that the cleaning force is moderate. In the above scheme, the counterweight can be moved manually, and the brush assembly 4 does not rotate throughout the process.

[0036] This design allows the counterweight balancing mechanism 6 to flexibly adjust the position and pressure of the brush assembly 4 according to the different heights of the candies, achieving precise cleaning. Whether it is a tall hard candy or a short soft candy, the position of the counterweight 62 can be adjusted to make the brush assembly 4 adapt to its height, achieving a good cleaning effect and ensuring the quality and efficiency of candy packaging.

[0037] The elastic connection assembly 5 includes a left fixed rod 51 mounted on the frame 1 and a right fixed rod 52 connected to the back of the brush assembly 4. An elastic ring 53 is wound between the left fixed rod 51 and the right fixed rod 52, and the axial length of the elastic ring 53 in its natural state is less than the initial distance between the two fixed rods. When the brush assembly 4 is deflected downward by the counterweight 62, the right fixed rod 52 moves downward with the brush assembly 4, forcing the elastic ring 53 to stretch and deform, generating a restoring force. When the counterweight 62 moves in the opposite direction, the restoring force of the elastic ring 53 assists the brush assembly 4 to reset and rise, enhancing the stability and reliability of the brush assembly 4's reset, and also providing an elastic buffer for the fine adjustment of the brush assembly 4.

[0038] The elastic ring 53 is made of silicone rubber or polyurethane. Both of these materials have good elasticity and durability and can withstand long-term tension and compression, ensuring the normal operation of the elastic connection component 5.

[0039] The counterweight block 62 has a counterweight cavity 7 inside, which contains adjustable counterweight particles 8. The counterweight particles 8 are tungsten alloy spheres with a diameter of 3-5mm, and multiple counterweight particles 8 are magnetically attracted to form an assembly. This design allows the weight of the counterweight block 62 to be flexibly adjusted according to actual needs, further improving the precision and adaptability of the brush assembly 4.

[0040] The counterweight-balanced brush adjustment device of this invention demonstrates significant multi-functional advantages in practical applications. By utilizing the movement of the counterweight 62 along the screw 61, the device can flexibly adjust the pressure applied by the brush assembly 4 for candies of different heights. This adjustment mechanism not only meets diverse cleaning needs but also ensures that, during the packaging process, both tall hard candies and short soft candies achieve the desired cleaning effect, effectively guaranteeing the stability of packaging quality.

[0041] The elastic structure design of the elastic connecting component 5 acts as a "stabilizing assistant" for the device, playing a crucial role in the deflection and reset process of the brush component 4. It endows the brush component 4 with excellent reset capability, enabling it to quickly return to its initial position during frequent cleaning actions, maintaining consistent cleaning force. Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art through this disclosure that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention; rather, the scope of protection is defined by the content of the claims.
