Description

Technical Field

[0001] This utility model relates to the field of infrared chalcogenide glass production technology, and in particular to a chamfering machine for square granules. Background Technology

[0002] Infrared chalcogenide glass lenses are mainly used in automotive and surveillance products. These lenses are primarily produced using two methods: precision molding or single-point diamond turning of infrared chalcogenide glass raw materials. Precision molding involves processing the raw material into pre-formed small spheres before molding.

[0003] The production process of infrared chalcogenide glass preforms is as follows: the outer circle cutting machine cuts the long strip of optical glass into short strips, the inner circle cutting machine cuts the short strips into square granules, and the square granules are then processed through a series of processes such as chamfering, rounding, fine grinding, polishing and cleaning to obtain infrared chalcogenide glass preforms.

[0004] Existing chamfering machines (such as the automatic chamfering machine disclosed in application number 202121211462.X) are not suitable for chamfering small-volume square granules, resulting in poor chamfering effect and low efficiency when chamfering square granules in batches. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a chamfering machine for square granules, which solves the technical problems that existing chamfering machines are not suitable for chamfering small-volume square granules, have poor chamfering effects on square granules, and have low efficiency in batch chamfering.

[0006] To achieve the above technical objectives, the present invention provides a chamfering machine for square granules, comprising:

[0007] A chamfering mechanism includes a chamfering body and a support body. The chamfering body has a chamfering cavity with a columnar structure. The top and bottom of the chamfering cavity are open. The support body is rotatably disposed in the chamfering cavity. There is a gap between the side wall of the support body and the cavity wall of the chamfering cavity. The support body is used to support granular material.

[0008] A drive mechanism, connected to the support body, is used to drive the support body to rotate so that the square granules on the support body collide with the cavity wall of the chamfered cavity;

[0009] A water supply mechanism, which is connected to the chamfered cavity, is used to apply water to the square particles on the support.

[0010] Furthermore, the square granule chamfering machine also includes a transmission mechanism, which is disposed in the chamfering cavity and located below the support body. The transmission mechanism abuts against the support body to convert the rotation of the support body into the up-and-down movement of the support body.

[0011] Furthermore, the support body includes a tray, multiple fixing rods, and multiple rollers. Each fixing rod is vertically arranged in a circular array below the tray, and the top of each fixing rod is fixedly connected to the tray. Each roller is connected to the bottom of each fixing rod in a corresponding manner. The transmission mechanism has multiple protrusions and multiple recesses, which are arranged intersectingly to form a circular track. The circular track abuts against each roller.

[0012] Furthermore, the top surface of the tray is a conical surface.

[0013] Furthermore, the transmission mechanism includes a support ring, multiple mounting rods, and multiple transmission blocks. The support ring is coaxial with the chamfered cavity. Each mounting rod is circumferentially arranged on the side of the support ring. One end of each mounting rod is fixedly connected to the support ring, and the other end of each mounting rod is fixedly connected to the chamfered body. Each transmission block is arranged in a ring array above the support ring and is fixedly connected to the support ring. A ramp is provided on both sides of each transmission block. The transmission block forms the protrusion, and the recess is formed between adjacent transmission blocks. Each transmission block corresponds to each roller.

[0014] Furthermore, the drive mechanism includes a main shaft and a drive assembly. The main shaft is vertically arranged and coaxial with the chamfered cavity. The main shaft has a spline section and a guide rod section from top to bottom. The spline section is located inside the chamfered cavity. A flower hole is coaxially opened on the tray, and the tray is fitted onto the spline section through the flower hole. The drive assembly is connected to the guide rod section and is used to drive the main shaft to rotate.

[0015] Furthermore, the water supply mechanism includes a water pipe and a water collection tank. One end of the water pipe is connected to a water source, and the other end of the water pipe is connected to the chamfered cavity. It is used to apply water to the square particles on the support body. The water collection tank is located below the chamfered body and is used to collect the water flowing out of the chamfered cavity.

[0016] Furthermore, a drain outlet is provided on the bottom of the water collection tank.

[0017] Furthermore, the chamfering mechanism also includes multiple supports, each of which is arranged circumferentially on the side of the chamfering body and connected to the chamfering body, so that there is a gap between the bottom of the chamfering body and the water collection tank.

[0018] Furthermore, the support body includes a first nut, a mounting plate, a screw, a second nut, and a third nut. The first nut is fixedly connected to the water collection tank.

The lower end of the screw is threadedly connected to the first nut. The second nut is located below the mounting plate and abuts against the bottom surface of the mounting plate. The second nut is threadedly connected to the screw. The third nut is located above the mounting plate and abuts against the top surface of the mounting plate. The third nut is threadedly connected to the screw.

[0019] Compared with the prior art, the beneficial effects of this utility model include: During use, square granules are poured into the chamfering cavity, where they fall onto the support body. The drive mechanism rotates the support body, causing it to collide with the cavity wall. This collision creates friction, achieving chamfering. During the chamfering process, a water supply mechanism applies water to the granules on the support body, cooling the material and reducing dust. The dust generated during chamfering is discharged through the gap between the support body and the chamfering cavity along with the water. The small gap also prevents material jamming. This square granule chamfering machine is suitable for chamfering smaller volumes of square granules, providing a good chamfering effect and high efficiency for batch chamfering.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0024] This utility model provides a chamfering machine for square granules, the structure of which is as follows: Figure 1 - Figure 2 As shown, the device includes a chamfering mechanism 100, a driving mechanism 200, and a water supply mechanism 300. The chamfering mechanism 100 includes a chamfering body 110 and a support body 120. The chamfering body 110 has a chamfering cavity 111 with a columnar structure. The top and bottom of the chamfering cavity 111 are open. The support body 120 is rotatably disposed within the chamfering cavity 111. There is a gap between the side wall of the support body 120 and the cavity wall of the chamfering cavity 111. The support body 120 is used to support granular material. The driving mechanism 200 is connected to the support body 120 and is used to drive the support body 120 to rotate so that the granular material on the support body 120 collides with the cavity wall of the chamfering cavity 111. The water supply mechanism 300 is connected to the chamfering cavity 111 and is used to apply water to the granular material on the support body 120.

[0025] In use, square granules are poured into the chamfering cavity 111, and the granules fall onto the support body 120. By operating the drive mechanism 200, the drive mechanism 200 drives the support body 120 to rotate. During the rotation of the support body 120, the square granules on the support body 120 collide with the cavity wall of the chamfering cavity 111. During the collision with the cavity wall of the chamfering cavity 111, the square granules rub against the cavity wall, thereby achieving chamfering of the square granules. During the chamfering process, the water supply mechanism 300 applies water to the square particles on the support body 120, which serves to cool them down and reduce dust. The powder generated during chamfering is discharged from the gap between the support body 120 and the chamfering cavity 111 along with the water. Due to the small gap, material jamming is avoided. This square particle chamfering machine is suitable for chamfering small-volume square particles, and it has a good chamfering effect on square particles. At the same time, it is highly efficient when chamfering square particles in batches.

[0026] As a preferred embodiment, please refer to Figure 2 The square granule chamfering machine further includes a transmission mechanism 400, which is disposed in the chamfering cavity 111 and located below the support body 120. The transmission mechanism 400 abuts against the support body 120 to convert the rotation of the support body 120 into the up-and-down movement of the support body. When the driving mechanism 200 drives the support body 120 to rotate, the transmission mechanism 400 can convert the rotation of the support body 120 into the up-and-down movement of the support body 120, thereby realizing the function of up-and-down material turning, which can prevent the square granules from touching the edge and further improve the chamfering effect of the square granules.

[0027] As a preferred embodiment, please refer to Figure 2The support body 120 includes a tray 121, multiple fixing rods 122, and multiple rollers 123. Each fixing rod 122 is vertically arranged in a circular array below the tray 121, with its top fixedly connected to the tray 121. Each roller 123 is correspondingly connected to the bottom of each fixing rod 122. The transmission mechanism 400 has multiple protrusions and multiple recesses, which are intersected and form a circular track. The circular track abuts against each roller 123. When the… When the drive mechanism 200 drives the tray 121 to rotate, each of the rollers 123 can rotate with the tray 121. When each of the rollers 123 reaches each of the protrusions, the tray 121 rises to the highest point. When each of the rollers 123 reaches each of the recesses, the tray 121 falls to the lowest point. Thus, the rotation of the tray 121 can be converted into the up and down movement of the carrier through each of the rollers 123, thereby realizing the function of up and down material turning. This can prevent the square granules from touching the edges and further improve the chamfering effect of the square granules.

[0028] As a preferred embodiment, please refer to Figure 2 The top surface of the tray 121 is a conical surface, which facilitates drainage. Water on the support body 120 can easily reach the gap between the support body 120 and the chamfered cavity 111.

[0029] As a preferred embodiment, please refer to Figure 2The transmission mechanism 400 includes a support ring 410, multiple mounting rods 420, and multiple transmission blocks 430. The support ring 410 is coaxial with the chamfered cavity 111. Each mounting rod 420 is circumferentially arranged on the side of the support ring 410. One end of each mounting rod 420 is fixedly connected to the support ring 410, and the other end of each mounting rod 420 is fixedly connected to the chamfered body 110. Each transmission block 430 is arranged in a ring array above the support ring 410 and is fixedly connected to the support ring 410. A ramp 431 is provided on both sides of each transmission block 430. The transmission block 430 forms the protrusion, and the recess is formed between adjacent transmission blocks 430. Each transmission block 430 corresponds one-to-one with each roller 123. When the drive mechanism 200... When the pallet 121 is driven to rotate, each roller 123 can rotate with the pallet 121 and rotate along the loop formed by each transmission block 430. When each roller 123 rotates to each transmission block 430 in a corresponding manner, each roller 123 abuts against each transmission block 430 in a corresponding manner, and the pallet 121 rises to the highest point. When each roller 123 rotates to the space between adjacent transmission blocks 430, each roller 123 abuts against the pallet 121, and the pallet 121 descends to the lowest point. Thus, the rotation of the pallet 121 can be converted into the up and down movement of the carrier through each roller 123, thereby realizing the function of up and down material turning, preventing the square granules from touching the edge, and further improving the chamfering effect of the square granules.

[0030] As a preferred embodiment, please refer to Figure 1 and Figure 2 The drive mechanism 200 includes a main shaft 210 and a drive assembly 220.

A splined hole 1211 is coaxially opened on the tray 121, and the tray 121 is fitted onto the splined section 211 through the splined hole 1211. The drive assembly 220 is connected to the smooth rod section 212 and is used to drive the main shaft 210 to rotate. The tray 121 can be limited by controlling the drive assembly 220 to connect with the splined section 211 through the splined hole 1211, so that the tray 121 can only move up and down along the main shaft 210 and cannot rotate relative to the main shaft 210. The drive assembly 220 drives the main shaft 210 to rotate, thereby driving the tray 121 to rotate.

[0036] As a preferred embodiment, please refer to Figure 2The support body 130 includes a first nut 131, a mounting plate 132, a screw 133, a second nut 134, and a third nut 135.

Then, each of the mounting holes is fitted onto each of the screw rods 133 one by one, and each of the third nuts 135 is threadedly fitted onto each of the screw rods 133 one by one, until each of the third nuts 135 abuts against the mounting plate 132, thereby completing the installation of the chamfered body 110. The chamfered body 110 is easy to install and remove.

[0042] To better understand this utility model, the following is combined with... Figure 1 - Figure 2 The working principle of the technical solution of this utility model will be described in detail below:

[0043] In use, square granules are poured into the chamfering cavity 111 and fall onto the tray 121. By operating the drive assembly 220, the drive assembly 220 drives the main shaft 210 to rotate, which in turn drives the support body 120 to rotate. As the tray 121 rotates, the square granules on it collide with the cavity wall of the chamfering cavity 111. During this collision, the granules rub against the cavity wall, thus achieving chamfering. During the chamfering process, water is applied to the square granules on the tray 121 through a water pipe, serving both a cooling and dust-reducing function. The dust generated during chamfering is discharged along with the water from the gap between the support body 120 and the chamfering cavity 111. The small gap also prevents material jamming. Since the main shaft 210 and the tray 121 are connected via a spline, ... When the tray 121 rotates, each of the rollers 123 can rotate with the tray 121, and each of the rollers 123 rotates along the loop formed by each of the transmission blocks 430. When each of the rollers 123 rotates to the corresponding transmission block 430, each of the rollers 123 abuts against the corresponding transmission block 430, and the tray 121 rises to the highest point. When each of the rollers 123 rotates to the adjacent transmission block 430, each of the rollers 123 abuts against the tray 121, and the tray 121 descends to the lowest point. Thus, the rotation of the tray 121 can be converted into the up and down movement of the carrier through each of the rollers 123, thereby realizing the function of up and down material turning. It can prevent the square granules from touching at the edge. This square granule chamfering machine is suitable for chamfering small-volume square granules, and has a good chamfering effect on square granules. At the same time, it has high efficiency when chamfering square granules in batches.

[0044] The square granule chamfering machine provided by this utility model has the following beneficial effects:

[0045] (1) When installing the chamfered body 110, the lower ends of each screw 133 are threadedly connected to each of the first nuts 131 one by one, and then each of the second nuts 134 are threadedly fitted onto each of the screw 133 one by one, and each of the second nuts 134 is at the same height. Then each of the mounting holes is threaded onto each of the screw 133 one by one, and each of the third nuts 135 is threaded onto each of the screw 133 one by one, until each of the third nuts 135 abuts against the mounting plate 132, thereby completing the installation of the chamfered body 110. The chamfered body 110 is easy to install and remove.

[0046] (2) When the tray 121 rotates, each of the rollers 123 can rotate with the tray 121, and each of the rollers 123 rotates along the loop formed by each of the transmission blocks 430. When each of the rollers 123 rotates to each of the transmission blocks 430, each of the rollers 123 abuts against each of the transmission blocks 430, and the tray 121 rises to the highest point. When each of the rollers 123 rotates to the adjacent transmission blocks 430, each of the rollers 123 abuts against the tray 121, and the tray 121 falls to the lowest point. Thus, the rotation of the tray 121 can be converted into the up and down movement of the carrier through each of the rollers 123, thereby realizing the function of up and down material turning, which can prevent the square granules from touching the edge and improve the chamfering effect.

[0047] (3) This square granule chamfering machine is suitable for chamfering small-volume square granules. It has a good chamfering effect on square granules and is highly efficient when chamfering square granules in batches.
