Description

Technical Field

[0001] This utility model relates to the field of tablet press technology, and in particular to a polyester resin tablet press. Background Technology

[0002] A polyester resin tablet press is an industrial device specifically designed to compress polyester resin powder into sheet-like products. Its core function is to achieve the molding and curing of powder through mechanical pressure.

[0003] Existing polyester resin tableting machines work by placing polyester resin raw materials into a concave mold, then using a hydraulic rod to move a punch closer to the concave mold. The punch then embeds itself inside the concave mold and squeezes the raw materials, thereby using mechanical pressure to compress the raw materials into tablets.

[0004] However, when the punch extrudes the raw material into sheets, some of the raw material may adhere to the surface of the punch. This causes the residual raw material on the surface to mix with other new raw materials during subsequent tableting, resulting in a messy raw material situation that affects the tableting quality. Utility Model Content

[0005] The technical problem to be solved by this utility model is that when the punch extrudes the raw material into sheets, some raw material may adhere to the surface of the punch, causing the residual raw material adhering to its surface to merge with other new raw materials during subsequent tableting, resulting in a messy raw material and affecting the tableting quality.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a polyester resin tableting machine, comprising: a machine body, the machine body being placed on the ground to support the overall components; a concave mold, the concave mold being detachably mounted on the machine body by screws; a convex mold, the convex mold being detachably mounted on the machine body by screws, wherein the convex mold is driven by a hydraulic rod to close with the concave mold to tablet the raw material; and a cleaning device, wherein the cleaning device is located on the side of the machine body near the convex mold, for cleaning residual raw material adhering to the surface of the convex mold.

[0007] Preferably, the cleaning device includes: a rectangular cylinder, which is detachably mounted on the side of the machine body near the punch via an assembly assembly; a gear, which is fixedly mounted on the rectangular cylinder via a self-locking motor, wherein the self-locking motor drives the gear to rotate; a rack, the surface of which is slidably connected to the inner wall of the rectangular cylinder, wherein the rack meshes with the gear; and a scraper, wherein the scraper is fixedly connected to the rack, and wherein the surface of the scraper is in contact with the surface of the punch.

[0008] The effect achieved by the above-mentioned components is as follows: By setting up a cleaning device, after the punch completes the tableting and resets, the self-locking motor is started to drive the gear to rotate, so that the gear drives the rack to move left and right along the inside of the rectangular cylinder, so that the rack drives the scraper to move closer to the punch, so that the scraper sticks to the surface of the punch during the movement and scrapes off the material adhering to it, thereby cleaning the residual material on the surface of the punch. This reduces the situation where the residual material adhering to the surface of the punch during subsequent tableting mixes with other new materials, causing the material to be messy and affecting the tableting quality, and improves the cleanliness and ease of cleaning of the surface of the punch.

[0009] Preferably, a shovel is fixedly connected to the side of the scraper near the punch, wherein the cross-section of the shovel is triangular, and the surface of the shovel is in contact with the surface of the punch.

[0010] The effect achieved by the above-mentioned components is as follows: by setting the scraper blade, the scraper blade can use its own angle to reduce the contact surface with the raw material, assist the scraper in removing the raw material, and further improve the scraping effect on the raw material.

[0011] Preferably, a T-slot is provided on one side of the rack, and a T-block is fixedly connected to the inner wall of the rectangular tube, wherein the T-block is placed inside the T-slot to limit the rack.

[0012] The effect achieved by the above components is that by setting T-blocks and T-slots, the T-blocks can be placed inside the T-slots to limit the rack, reducing the rack from shaking or tilting during movement and affecting normal transmission.

[0013] Preferably, a rubber block is fixedly connected to one side of the toothed rod.

[0014] The effect achieved by the above components is that by setting up rubber blocks, the rubber blocks can separate the rack and the rectangular tube during the movement process, reducing the direct collision between one end of the rack and the surface of the rectangular tube when it moves to the maximum position, thus preventing severe wear on both and affecting their service life.

[0015] Preferably, the assembly component includes: a positioning frame, which is fixedly connected to the side of the machine body near the punch, wherein the inner wall of the positioning frame is threaded with bolts; and a circular hole plate, which is fixedly connected to the rectangular tube, wherein the circular hole plate is placed inside the positioning frame and fixed by bolts.

[0016] The effect achieved by the above components is as follows: by setting the assembly components, the rectangular cylinder is first moved manually to drive the circular hole plate to move. When the circular hole plate moves to the position inside the insertion slot frame, the bolt is manually screwed into the slot frame and the circular hole plate, so that the bolt fixes the circular hole plate inside the slot frame, thereby achieving the assembly and fixation between the rectangular cylinder and the machine body. At the same time, the rectangular cylinder can be disassembled later, improving the flexibility of use and the convenience of maintenance of the cleaning device.

[0017] Preferably, one end of the bolt is fixedly connected to a screw block, wherein the surface of the screw block is provided with multiple anti-slip protrusions.

[0018] The effect achieved by the above components is that by setting the screw-in block, the contact area of ​​the bolt can be increased, thereby improving the convenience and stability of manually turning the bolt.

[0019] Preferably, it further includes: a collection assembly, the collection assembly comprising: a sleeve fixedly connected to the scraper rod, wherein the sleeve is positioned on the side of the scraper rod away from the punch; and a collection box, the surface of which is slidably connected to the inner wall of the sleeve, wherein the collection box is placed inside the sleeve to store the scraped material.

[0020] The effect achieved by the above components is as follows: by setting up a collection component, when the scraper removes the material adhering to the surface of the punch, the scraped material falls into the collection box inside the lower sleeve for storage, thereby collecting the scraped material and reducing the scraped material from falling onto the die, causing the die surface to become dirty and affecting the subsequent tableting.

[0021] The beneficial effects of this utility model are:

[0022] By setting up a cleaning device, residual material adhering to the surface of the punch can be quickly removed, reducing the possibility of residual material adhering to the surface of the punch mixing with other new materials during subsequent tableting, causing material disorder and affecting the tableting quality, thus improving the cleanliness and ease of cleaning of the punch surface.

[0031] Figure 1-4 A polyester resin tableting machine is shown, comprising: a machine body 1, which is placed on the ground to support the entire assembly; a die 2, which is detachably mounted on the machine body 1 by screws; a punch 3, which is detachably mounted on the machine body 1 by screws, wherein the punch 3 is driven by a hydraulic rod to close with the die 2 to tablet the raw material; and a cleaning device 4, wherein the cleaning device 4 is located on the side of the machine body 1 near the punch 3, and is used to clean residual raw material adhering to the surface of the punch 3.

[0032] Figure 3 and Figure 4 The cleaning device 4 shown includes: a rectangular cylinder 41, which is detachably mounted on the side of the machine body 1 near the punch 3 via an assembly assembly 5; a gear 42, which is fixedly mounted on the rectangular cylinder 41 via a self-locking motor, wherein the self-locking motor drives the gear 42 to rotate; a rack 44, the surface of which is slidably connected to the inner wall of the rectangular cylinder 41, wherein the rack 44 meshes with the gear 42; and a scraper 45, which is fixedly connected to the rack 44, wherein the surface of the scraper 45 is in contact with the surface of the punch 3. By setting the cleaning device 4, when the punch 3 completes pressing... After the tablets are reassembled, the self-locking motor is started to drive the gear 42 to rotate. This causes the gear 42 to drive the rack 44 to move left and right along the inside of the rectangular cylinder 41. The rack 44 then drives the scraper 45 to move closer to the punch 3. As the scraper 45 moves, it adheres to the surface of the punch 3 and scrapes off the material adhering to it. This cleans the surface of the punch 3 of residual material, reducing the possibility of residual material adhering to the surface of the punch 3 mixing with other new materials during subsequent tableting, which could cause material disorder and affect the tableting quality. This improves the cleanliness and ease of cleaning of the surface of the punch 3.

[0033] Figure 3 and Figure 4The scraper 45 shown is fixedly connected to a scraper 46 near the punch 3. The scraper 46 has a triangular cross-section and its surface is in contact with the surface of the punch 3. By setting the scraper 46, the scraper 46 can reduce the contact area with the material by using its own angle, assisting the scraper 45 in removing the material and further improving the scraping effect. A T-slot 47 is opened on one side of the toothed rod 44. A T-block 43 is fixedly connected to the inner wall of the rectangular tube 41. The T-block 43 is placed inside the T-slot 47 to limit the toothed rod 44. By setting the T-block 43 and the T-slot 47, the T-block 43 can be placed inside the T-slot 47 to limit the toothed rod 44, reducing the possibility of the toothed rod 44 shaking or tilting during movement, which would affect the normal transmission.

[0034] Figure 3 and Figure 4 A rubber block 48 is fixedly connected to one side of the toothed rod 44. By setting the rubber block 48, the rubber block 48 can separate the toothed rod 44 from the rectangular tube 41 during the movement process, reducing the direct collision between one end of the toothed rod 44 and the surface of the rectangular tube 41 when it moves to the maximum position, which would cause severe wear on both and affect the service life.

By setting the assembly component 5, the rectangular tube 41 is first manually moved to move the circular hole plate 54. When the circular hole plate 54 moves to the position where it is inserted into the locking frame 51, the bolts 52 are manually screwed into the locking frame. Inside the circular hole plate 54 and the 51, the bolt 52 is fixed to the circular hole plate 54 inside the 51, thereby achieving the assembly and fixation between the rectangular cylinder 41 and the machine body 1. At the same time, the rectangular cylinder 41 can be disassembled later, improving the flexibility of use and the convenience of maintenance of the cleaning device 4. One end of the bolt 52 is fixedly connected to a screw block 53, wherein the surface of the screw block 53 is provided with multiple anti-slip protrusions. By setting the screw block 53, the contact area of ​​the bolt 52 can be increased, improving the convenience and stability of manually turning the bolt 52.

[0036] Figure 4The assembly also includes a collection component 6, comprising: a sleeve 61 fixed to the scraper 45, wherein the sleeve 61 is positioned on the side of the scraper 45 away from the punch 3; and a collection box 62, the surface of which is slidably connected to the inner wall of the sleeve 61, wherein the collection box 62 is placed inside the sleeve 61 to store the scraped material. By setting up the collection component 6, when the scraper 45 scrapes off the material adhering to the surface of the punch 3, the scraped material falls into the collection box 62 inside the lower sleeve 61 for storage, thus achieving the collection of the scraped material and reducing the amount of scraped material scattered onto the die 2, preventing the die 2 surface from becoming dirty and affecting subsequent tableting.

[0037] Working principle: First, the polyester resin raw material is placed into the concave mold 2. Then, the hydraulic rod drives the punch 3 to move closer to the concave mold 2. The punch 3 then embeds into the concave mold 2 to squeeze the raw material, thereby using mechanical pressure to press the raw material into sheets.

[0038] First, manually move the rectangular cylinder 41 to move the perforated plate 54. When the perforated plate 54 moves to the position inside the insertion slot frame 51, manually screw the bolt 52 into the slot frame 51 and the perforated plate 54, so that the bolt 52 fixes the perforated plate 54 inside the slot frame 51, thereby achieving the assembly and fixation between the rectangular cylinder 41 and the machine body 1. After the punch 3 completes the pressing and reset, start the self-locking motor to drive the gear 42 to rotate, so that the gear 42 drives the rack 44 to move left and right along the inside of the rectangular cylinder 41, so that the rack 44 drives the scraper 45 to move towards the punch 3, so that the scraper 45 scrapes off the material adhering to the surface of the punch 3 during the movement, so that the scraped material falls into the collection box 62 inside the lower sleeve 61 for storage, thereby achieving the removal of residual material on the surface of the punch 3.
