Description

Technical Field

[0001] This utility model relates to the field of candy processing screening technology, specifically a candy anti-sticking screening device with a multi-level screen that can be replaced. Background Technology

[0002] After the gummies are poured, two people are needed to manually pick out defective products in the semi-finished product area. However, this process is not thorough, and some defective products may be transferred to the next stage. The screening device can automatically screen the processed candies. In addition, since gummies have a certain degree of stickiness, the vibration screening process can disperse the gummies that are stuck together, thereby improving the quality of candy processing.

[0003] For example, patent CN222919070U discloses a candy screening device, including a box body, a box cover fixedly installed on the top of the box body, a feed hopper fixedly installed on the top surface of the box cover, a sieve plate set inside the box body, a fixing plate fixedly installed on the side of the sieve plate, a shell fixedly installed on the side of the box body, a fixing rod fixedly installed inside the shell, a spring sleeved on the surface of the fixing rod, and a vibration motor fixedly installed on the side of the box body. The sieve plate swings left and right inside the shell through the fixing plate, effectively separating candies and improving the screening accuracy and efficiency. The symmetrical layout of the fixing rod maintains the stability and uniformity of screening, further improving screening efficiency. The design of the inclined plate and the lower discharge chute ensures that candies can be accurately discharged, effectively reducing unqualified products and thus improving product quality. The size difference of processed candies is large, and the sieve with the same mesh size is difficult to adapt to candies of different sizes, making it difficult to screen defective candies with size variations. Some existing screening devices only have a sieve of one size, and sieve replacement requires manual control, which is complicated and not conducive to the application of screening devices in intelligent production lines.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing candy anti-sticking screening device. Utility Model Content

[0005] The purpose of this utility model is to provide a candy anti-sticking screening device with replaceable multi-level screens, in order to solve the problems mentioned in the background art, such as the large size difference of processed candies, the difficulty of using a screen with the same mesh size to adapt to candies of different sizes, the difficulty of screening out defective candies with size variations, and the fact that some existing screening devices only have a screen of one size, and screen replacement requires manual control, which is complicated to operate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer screen replacement candy anti-sticking screening device, comprising a support frame and a screening frame vibrating above it, multiple vibration spring modules elastically connected between the support frame and the screening frame, a vibrator providing vibration force installed at the bottom of the screening frame, a protective frame fixedly connected to the side of the screening frame away from the outlet end, and a through groove communicating with the interior of the protective frame on the screening frame, multiple guide strips fixed at equal intervals on the inner walls of the screening frame and the protective frame, and rectangular screens slidably connected to the guide strips; multiple rectangular screens are arranged longitudinally inside the protective frame, and the screen hole size of the multiple rectangular screens gradually increases from top to bottom, and a moving mechanism is provided in the protective frame for replacing rectangular screens of different hole diameters in the screening frame.

[0007] Preferably, the rectangular screen has guide grooves on its sides that slide with the guide strips; the front and rear ends of the multiple rectangular screens are sealed and engaged in the through grooves.

[0008] Preferably, the moving mechanism includes multiple strip slots longitudinally and equally spaced on the protective frame, with the multiple strip slots and multiple guide strips alternating longitudinally; a drive frame is slidably connected in the strip slots, and the drive frame is slidably sleeved on the outside of the protective frame; an L-shaped strip is fixed in the center of one end surface of the rectangular screen near the protective frame, and the drive frame is engaged with the L-shaped strip.

[0009] Preferably, a threaded rod is rotatably connected to the protective frame and the screening frame, and an internal threaded disc is fitted onto the outer thread of the threaded rod; an electric lifting rod is fixedly installed on the upper end face of the internal threaded disc, and the output end of the electric lifting rod is fixedly connected to the drive frame.

[0010] Preferably, multiple electromagnets are fixed at equal intervals along the longitudinal direction on the protective frame, and a magnetic block attracted by the electromagnets is fixed on one end surface of the rectangular screen near the protective frame.

[0011] Preferably, a feeding disc is slidably provided at the outlet end of the screening frame, and the feeding disc moves to be flush with the surface of the rectangular screen.

[0012] Preferably, a lifting bracket is fixed on the screening frame, and the lifting bracket is engaged and slidably installed on the screening frame; a slider is engaged and slidably connected to the screening frame in the horizontal direction, and the slider is fixedly installed on the drive frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the multi-level screen replaceable candy anti-sticking screening device can automatically replace rectangular screens with different sizes of screen holes installed in the screening frame, so that the equipment can adapt to screening candies of different sizes, and can shake and disperse the candies during the screening process to avoid the candies sticking together and improve the candy processing quality.

[0014] Furthermore, the protective frame is equipped with a moving mechanism for replacing rectangular screens of different aperture sizes into the screening frame. The mechanism controls the movement of the drive frame, which moves to the side of the rectangular screen of the corresponding aperture size and engages with the L-shaped locking strip on the side of the rectangular screen. Then, the drive frame is controlled to move laterally, pushing the rectangular screen to be installed into the screening frame, thus achieving the purpose of automatically replacing the rectangular screen. The mechanical replacement operation is convenient.

[0015] Furthermore, during the longitudinal movement of the control drive frame, the drive frame can drive the lifting bracket to move synchronously via the slider. The lifting bracket controls the feeding tray to move up and down synchronously, adjusting the height position of the feeding tray on the side of the screening frame, keeping the feeding tray and the replacement rectangular screen at the same height position, so as to transfer the screened candies.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: Please refer to Figures 1-6 This utility model provides the following technical solution: a multi-layer screen replacement candy anti-sticking screening device, including a support frame 1 and a screening frame 3 vibrating and mounted on it. Multiple vibration spring modules 2 are elastically connected between the support frame 1 and the screening frame 3. A vibrator 4 providing vibration force is installed at the bottom of the screening frame 3. A protective frame 5 is fixedly connected to the side of the screening frame 3 away from the outlet end, and a through groove 6 is opened on the screening frame 3, communicating with the interior of the protective frame 5. Multiple guide strips 7 are fixed at equal intervals on the inner walls of the screening frame 3 and the protective frame 5. Rectangular screens 8 are slidably connected to the guide strips 7. Multiple rectangular screens 8 are arranged longitudinally inside the protective frame 5, and the screen hole size of the multiple rectangular screens 8 gradually increases from top to bottom. A moving mechanism is provided in the protective frame 5 to replace rectangular screens 8 with different hole diameters in the screening frame 3. Guide grooves 9 are opened on the sides of the rectangular screens 8, slidingly engaging with the guide strips 7. The front and rear ends of the multiple rectangular screens 8 are sealed and engaged in the through grooves 6.

[0028] Please see Figures 4-7 The moving mechanism includes multiple strip slots 10 longitudinally and equally spaced on the protective frame 5, with the multiple strip slots 10 and multiple guide strips 7 longitudinally alternating; a drive frame 11 is slidably connected in the strip slots 10, and the drive frame 11 is slidably sleeved on the outside of the protective frame 5; an L-shaped strip 12 is fixed in the center of one end surface of the rectangular screen 8 near the protective frame 5, and the drive frame 11 is engaged with the L-shaped strip 12.

[0029] Please see Figures 3-8 A threaded rod 13 is rotatably connected to the protective frame 5 and the screening frame 3. An internal threaded disc 14 is fitted onto the outer thread of the threaded rod 13. An electric lifting rod 15 is fixedly installed on the upper end face of the internal threaded disc 14, and the output end of the electric lifting rod 15 is fixedly connected to the drive frame 11. Multiple electromagnets 16 are fixedly fixed longitudinally at equal intervals on the protective frame 5. A magnetic block 17 attracted by the magnetism of the electromagnet 16 is fixed to the surface of the rectangular screen 8 near one end of the protective frame 5.

[0030] The processed candy enters the sieve frame 3, and the vibrator 4 is run to make the sieve frame 3 vibrate. With the assistance of the vibration spring module 2, the sieve frame 3 vibrates rapidly to screen the candy. The rectangular screen 8 can vibrate to disperse the sticky candy, and the candy that is defective in size is separated through the screen holes of the rectangular screen 8. The qualified candy and the unqualified candy are discharged from the top and bottom respectively, which improves the quality of the processed candy.

[0031] Rectangular screens 8 with different aperture sizes are installed in the sieving frame 3 according to the size of the candy to be processed. Multiple rectangular screens 8 are housed in the protective frame 5. The rectangular screens 8 are magnetically attracted by the magnets 17 on their sides and the electromagnets 16 in the protective frame 5, thus limiting their position. The motor fixed on the protective frame 5 controls the rotation of the threaded rod 13, which in turn controls the lateral movement of the internal threaded disc 14 under threaded transmission. The internal threaded disc 14 can adjust the lateral position of the drive frame 11. The electric lifting rod 15 on the internal threaded disc 14 can control the drive frame. 11. Longitudinal movement: By adjusting the lateral and longitudinal positions of the drive frame 11, the drive frame 11 can be controlled to move and engage with the side of the rectangular screen 8 at the corresponding position, so that it engages with the L-shaped locking strip 12 on the side of the rectangular screen 8. Then, by controlling the lateral movement of the drive frame 11, the rectangular screen 8 can be pushed into the screening frame 3. The rectangular screen 8 is engaged with the guide grooves 9 on both sides and moves laterally outside the guide strip 7, maintaining the accuracy of its installation position. The mechanical replacement of the rectangular screen 8 is convenient and can be quickly adapted to the processing of candies of different sizes.
