Description

Technical Field

[0001] This utility model relates to the technical field of ice crushers for food refrigeration, specifically an ice crusher for quick-frozen foods equipped with a noise reduction structure. Background Technology

[0002] Quick-frozen foods refer to foods that are rapidly frozen. Freezing reduces the growth of microorganisms in the food, thereby extending its shelf life. Ice crushers play an important role in the production of quick-frozen foods, especially in pre-cooling, temperature control, and auxiliary quick-freezing. Through efficient ice making and precise temperature management, they significantly improve product quality and production efficiency.

[0003] In the prior art, Chinese Patent Application No. CN202121721261.4 discloses an ice crushing device for quick-frozen food processing, including a crusher body, a cylindrical roller bearing, a lead screw, a first asynchronous motor, a moving frame, a first telescopic rod, a rotating shaft, ice crushing blades, a second asynchronous motor, and a protective spring. The cylindrical roller bearing is installed on the right side wall of the crusher body. The right end of the lead screw is fixed inside the cylindrical roller bearing. The two threads on the lead screw are opposite in direction. The left end of the lead screw is connected to the first asynchronous motor through a coupling. The first asynchronous motor is fixed on the left outer surface of the crusher body. Two moving frames are provided on the lead screw, and the two moving frames are respectively installed on the two opposite threads of the lead screw.

[0004] Based on the above information, it can be seen that existing ice crushers generally crush ice blocks by rotating ice-crushing blades. However, in actual use, when faced with larger ice blocks, the blades have difficulty crushing them and require a large impact force to achieve the crushing effect. During this process, the blades hitting the ice blocks will produce a loud noise, which will affect the health of the workers. Utility Model Content

[0005] The purpose of this invention is to provide an ice crusher for quick-frozen foods with a noise reduction structure, so as to solve the problem of excessive noise during operation mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ice crusher for quick-frozen food with a noise reduction structure, comprising a square crushing box, a receiving baffle for placing ice blocks fixedly installed above the crushing box, and a feeding trough corresponding to the crushing box being opened in the middle of the receiving baffle, an ice discharge hopper connected to the left side of the crushing box being fixedly installed, two mutually symmetrical crushing rollers being rotatably installed inside the crushing box, and the crushing rollers being driven to rotate by a drive motor fixedly installed outside the crushing box; a guide baffle being fixedly installed at the upper end inside the crushing box, and crushing teeth evenly distributed on the upper surface of the guide baffle being fixedly installed; a sound insulation plate being fixedly installed on the inner wall of the crushing box, and an inner partition plate evenly distributed inside the sound insulation plate being fixedly installed.

[0007] Preferably, the guide baffle has an inclined structure, and the guide baffle corresponds to the position of the crushing roller, and sound-absorbing cotton is fixedly installed on the lower surface of the guide baffle.

[0008] Preferably, a support plate for receiving broken ice is installed on the lower inner side of the sound insulation panel, and the support plate is rotatably connected to the sound insulation panel via a connecting hinge.

[0009] Preferably, a buffer spring is installed below the front end of the bearing plate, and both the upper and lower ends of the buffer spring are rotatably connected.

[0010] Preferably, the support plate is located above the ice outlet, and the upper surface of the support plate is made of soft rubber material.

[0011] Preferably, an installation block is fixedly provided on the lower outer surface of the crushing box, and a sliding support leg is installed through the inside of the installation block.

[0012] Preferably, a shock-absorbing spring that is pressed against the mounting block is installed on the lower end of the support leg, and a damper that is fixedly installed on the outer surface of the crushing box and connected to the upper end of the support leg is installed.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the ice crusher for quick-frozen food equipped with a noise reduction structure adopts a novel structural design, the specific details of which are as follows:

[0014] 1. Ice blocks enter the crushing chamber through the feed chute. The crushing rollers inside the crushing chamber crush the ice blocks. Before that, the ice blocks fall onto the guide baffle. The crushing teeth on the guide baffle initially crush the ice blocks, making it easier for the subsequent crushing rollers to crush the ice blocks, thereby reducing the noise generated during crushing.

[0015] Furthermore, a sound insulation panel is installed inside the crushing chamber. The sound insulation panel has an inner partition, which divides the inside of the sound insulation panel into multiple cavities. The cavities are used to absorb sound and reduce the transmission of noise to the outside.

[0016] Furthermore, the broken ice blocks fall onto the support plate, where the rubber material and the buffer springs below provide cushioning, thus reducing the damage caused by the falling ice blocks.

[0017] 2. During the use of the device, it is supported by the support legs. When the device rotates inside, it causes the whole device to vibrate. During this process, the shock-absorbing springs on the outside of the support legs absorb the vibration force, and the damper absorbs the excess force of the shock-absorbing springs, so as to achieve the purpose of shock absorption of the whole device. The purpose of noise reduction can also be achieved through shock absorption. Attached Figure Description

[0025] 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.

[0026] Example 1: Please refer to Figures 1-5This embodiment aims to reduce the operating noise of the device and provides the following technical solution, specifically: a square-shaped crushing box 1, with a receiving baffle 2 for placing ice blocks fixedly installed on the top of the crushing box 1, and a feeding chute 3 corresponding to the crushing box 1 opened in the middle of the receiving baffle 2. An ice discharge hopper 4 connected to the crushing box 1 is fixedly installed on the left side of the crushing box 1. Two symmetrical crushing rollers 5 are rotatably installed inside the crushing box 1, and the crushing rollers 5 are driven to rotate by a drive motor 6 fixedly installed outside the crushing box 1. The upper part of the inside of the crushing box 1 is fixedly... A guide baffle 7 is fixedly installed, and crushing teeth 8 are fixedly installed at equal intervals on the upper surface of the guide baffle 7. A sound insulation plate 10 is fixedly installed on the inner wall of the crushing box 1, and an inner partition plate 11 with equal intervals is fixedly installed inside the sound insulation plate 10. The guide baffle 7 has an inclined structure, and the guide baffle 7 corresponds to the position of the crushing roller 5. Sound-absorbing cotton 9 is fixedly installed on the lower surface of the guide baffle 7. A bearing plate 12 for receiving crushed ice is installed on the lower inner side of the sound insulation plate 10, and the bearing plate 12 is rotatably connected to the sound insulation plate 10 through a connecting hinge 13.

[0027] When using the device, first place the ice block to be crushed inside the receiving baffle 2, and then put the ice block into the crushing box 1 through the feed chute 3. At this time, the ice block first falls onto the guide baffle 7. The impact force of the fall, together with the crushing teeth 8 on the guide baffle 7, initially crushes the ice block. The ice block after initial crushing falls to the position of the crushing roller 5. The drive motor 6 drives the crushing roller 5 to rotate. The rotation of the crushing roller 5 thoroughly crushes the ice block (the ice block after initial crushing is crushed again by the crushing roller 5 to reduce the difficulty, thereby reducing the noise when the crushing roller 5 is crushing). In addition, during the crushing process, the sound insulation plate 10, together with its internal inner partition 11, absorbs sound and further reduces the noise transmission.

[0028] Example 2: Please refer to Figure 3 and Figure 6 This embodiment achieves the purpose of shock absorption of the device and provides the following technical solution, specifically: a buffer spring 14 is installed below the front end of the bearing plate 12, and the upper and lower ends of the buffer spring 14 are rotatably connected. The bearing plate 12 is located above the ice outlet 4, and the upper surface of the bearing plate 12 is made of soft rubber material. An installation block 15 is fixedly installed on the lower outer surface of the crushing box 1, and a support leg 16 is slidably installed through the installation block 15. A shock-absorbing spring 17 that is pressed against the installation block 15 is installed on the lower outer side of the support leg 16, and a damper 18 connected to the upper end of the support leg 16 is fixedly installed on the outer surface of the crushing box 1.

[0029] After the ice blocks break, they fall onto the support plate 12. The rubber material on the top of the support plate 12, together with the buffer spring 14 below it, is used to buffer the ice. Then, the support plate 12 rotates around the connecting hinge 13 under the weight of the ice blocks, and finally discharges the ice blocks from the ice outlet 4. During the operation of the device, vibrations are generated. At this time, the shock-absorbing spring 17 on the outside of the support leg 16 absorbs the vibration force, and at the same time, the damper 18 absorbs the rebound force of the shock-absorbing spring 17, so as to achieve the purpose of overall vibration reduction of the device.
