Description

Technical Field

[0001] This utility model relates to the field of edge trimming technology, and in particular to a device for trimming the edges of raw rubber on food boots. Background Technology

[0002] In the production of food-grade rubber or plastic products, such as food boots (boot-shaped molded products used for food packaging or special food molding), after molding, their edges often retain burrs, flash, or excess rubber material, known as "raw rubber edges." Currently, the trimming of these product edges is mostly done manually with hand-held cutters or using simple clamps in conjunction with manual trimming tools. However, manual trimming methods suffer from low efficiency, high labor intensity, uneven cutting edges, and poor precision. Furthermore, operators are prone to fatigue from prolonged work, leading to inconsistent product quality. In addition, manual operation makes it difficult to ensure consistent trimming paths, easily resulting in over-cutting or inadequate trimming, affecting the product's sealing performance and usability.

[0003] Some companies have attempted to use mechanical trimming equipment, but existing equipment is mostly designed for metal or rigid plastic parts and cannot adapt to the characteristics of soft, elastic materials used in food-grade boots. For example, soft cylindrical products are prone to deformation, shrinkage, or closure during trimming, making it difficult for the blade to cut stably. Furthermore, the lack of effective spreading and circumferential positioning mechanisms makes it difficult to achieve continuous, closed-loop edge trimming. In addition, traditional equipment typically lacks waste collection capabilities, allowing trimming debris to easily scatter inside the equipment or in the working environment, posing a risk of secondary contamination and failing to meet the stringent cleanliness requirements of food production.

[0004] Therefore, it is necessary to design a device for trimming the edges of the original rubber on food boots to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing food boot raw rubber edge trimming processes, such as low efficiency, uneven cutting, poor precision, lack of support structure, inability to stably clamp soft cylindrical products, discontinuous trimming path, and waste spillage and pollution, this utility model provides a food boot raw rubber edge trimming device.

[0006] The technical solution is as follows: A food boot raw rubber edge trimming device, comprising a base, a controller, a mounting base, a mounting frame, a second electric push rod, a fixing plate, a core column, an electric circular guide rail, a slider, a micro motor, and a trimming knife. The controller is installed on the front side of the top of the base, and the mounting base is fixedly connected to the rear side of the top of the base. The mounting frame is fixed on the left and right sides and the upper rear side of the mounting base, forming a semi-enclosed structure together with the mounting base. The second electric push rod with its telescopic end facing downward is fixedly connected to the top of the mounting frame. The telescopic end of the second electric push rod is fixedly connected to the fixing plate. The core column is fixedly connected to the bottom of the fixing plate. The electric circular guide rail is fixedly connected to the front and rear sides of the bottom of the fixing plate. The electric circular guide rail is arranged around the upper outer periphery of the core column and is adapted to the shape of the core column. The slider is slidably connected to the inner ring of the electric circular guide rail. The micro motor is fixedly connected to the outer side of the slider. The output shaft of the micro motor is inclined towards the center of the core column. The output shaft of the micro motor is fixedly connected to the trimming knife. The second electric push rod and the micro motor are both electrically connected to the controller.

[0007] As a further preferred embodiment, it also includes a vertical guide rail, a first electric push rod, and a positioning seat. The top of the mounting seat is fixedly connected to the vertical guide rail, and the first electric push rod is installed on the front side of the top of the base. The output shaft of the first electric push rod faces the rear, and its telescopic end is fixedly connected to the positioning seat. The telescopic rod of the first electric push rod passes through the middle of the mounting seat and slides with it. The positioning seat slides with the vertical guide rail. The top of the positioning seat is provided with two U-shaped limit blocks arranged opposite each other. The limit blocks have a certain height and are adapted to the shape of the front and rear sides of the food boot. The first electric push rod is electrically connected to the controller.

[0008] As a further preferred option, it also includes a guide block, with a trapezoidal guide block that is wider at the top and narrower at the bottom fixedly connected to the bottom of the core column.

[0009] As a further preferred embodiment, it also includes a bidirectional motor, a screw, a sliding plate, and a clamping frame. The bidirectional motor is installed on the rear side of the mounting frame, and the output shafts on both sides of the bidirectional motor are fixedly connected to the screw. Limiting grooves are provided on the left and right sides of the mounting frame, and the sliding plate is slidably connected to the mounting frame through the limiting grooves. The bottom of the sliding plate is slidably engaged with the mounting base. The clamping frame is fixedly connected to the upper part of the side where the two sliding plates are close to each other. The top of the clamping frame is open and hollow inside. The middle of the side where the two clamping frames are close to each other is provided with a recess that matches the core column and the outer periphery of the food shoe. The bidirectional motor is electrically connected to the controller.

[0010] As a further preferred embodiment, it also includes upper limit blocks and lower limit blocks. Two upper limit blocks are fixedly connected to the upper part of each side of the two sliding plates that are close to each other. The upper limit blocks have elastic deformation capability and correspond to the upper two sides of the pressing frame. Two lower limit blocks are fixedly connected to the lower part of each side of the two sliding plates that are close to each other and correspond to the lower two sides of the pressing frame.

[0011] As a further preferred embodiment, it also includes a fixed block, a pull rod, a locking block, and a spring. The fixed block is fixedly connected to the sliding plate at a position below the lower limit block. Multiple pull rods pass through the fixed block and are slidably connected to it. The upper end of the pull rod is fixedly connected to the locking block. The bottom of the pressing frame has a locking groove that matches the shape of the locking block at the position corresponding to the locking block. Multiple springs are set between the locking block and the fixed block, and the springs are sleeved around the pull rod.

[0012] This utility model has the following advantages: 1. This utility model uses an electric ring guide rail on a fixed plate to drive the slider and its outer micro motor and trimming blade to move continuously along the circumference of the core column. At the same time, the trimming blade is tilted towards the center of the core column, which achieves all-round, dead-angle-free continuous trimming of the top edge of the food boot, thus improving trimming accuracy and work efficiency.

[0013] 2. This utility model uses a guide block with a trapezoidal structure that is wider at the top and narrower at the bottom. The guide block is inserted into the top opening of the closed food boot under the action of the second electric push rod. The inclined structure opens the opening of the boot, which achieves the effect of quickly and stably opening the working area, making it easier for subsequent clamping and trimming operations.

[0014] 3. This utility model achieves the detachable and quick installation and replacement of the pressing frame by setting an elastic locking mechanism consisting of a pull rod, a locking block, and a spring on the sliding plate and opening a slot at the corresponding position at the bottom of the pressing frame. This facilitates the cleaning of trimming waste, maintenance and replacement of easily damaged parts, and improves the ease of use and maintenance efficiency of the equipment.

Detailed Implementation

[0024] A device for trimming the edges of raw rubber on food boots, such as Figures 1-6 As shown, the device includes a base 1, a controller 2, a mounting base 3, a mounting frame 4, a second electric push rod 8, a fixing plate 9, a core column 10, a guide block 11, an electric circular guide rail 12, a slider 13, a micro motor 14, and a trimming knife 15. The controller 2 is mounted on the front top of the base 1. The mounting base 3 is bolted to the rear top of the base 1. The mounting frame 4 is fixed to the left, right, and rear top sides of the mounting base 3, forming a semi-enclosed structure together with the mounting base 3. The top of the mounting frame 4 is bolted to the second electric push rod 8 with its telescopic end facing downwards. The telescopic end of the second electric push rod 8 is bolted to the fixing plate 9. The bottom of the fixing plate 9 is bolted to the core column 10. The bottom of the core column 10... The trapezoidal guide block 11, which is wider at the top and narrower at the bottom, is connected by bolts to open and close the top of the food boot A cylinder. The bottom front and rear sides of the fixing plate 9 are connected to the electric ring guide rail 12 by bolts. The electric ring guide rail 12 is arranged around the upper outer periphery of the core column 10 and is adapted to the shape of the core column 10. The inner ring of the electric ring guide rail 12 is slidably connected to the slider 13. The outer side of the slider 13 is connected to the micro motor 14 by bolts. The output shaft of the micro motor 14 is inclined towards the center of the core column 10 to adapt to the trimming operation of the top corner of the food boot A cylinder. The output shaft of the micro motor 14 is connected to the trimming knife 15 by welding. The second electric push rod 8 and the micro motor 14 are both electrically connected to the controller 2.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, it also includes a vertical guide rail 5, a first electric push rod 6, and a positioning seat 7. The top of the mounting base 3 is connected to the vertical guide rail 5 by bolts. The first electric push rod 6 is installed on the front side of the top of the base 1. The output shaft of the first electric push rod 6 faces the rear side, and its telescopic end is connected to the positioning seat 7 by bolts. The telescopic rod of the first electric push rod 6 passes through the middle of the mounting base 3 and slides with it. The positioning seat 7 slides with the vertical guide rail 5 and is used to move stably in the vertical direction under the push of the first electric push rod 6. The top of the positioning seat 7 is provided with two U-shaped limit blocks arranged opposite each other. The limit blocks have a certain height and are adapted to the front and rear sides of the food boot A. When the first electric push rod 6 is activated, the positioning seat 7 moves backward along the vertical guide rail 5 to the upper part of the mounting base 3 and the inner side of the mounting frame 4. The first electric push rod 6 is electrically connected to the controller 2.

[0026] like Figure 5 , Figure 6 and Figure 7 As shown, it also includes a bidirectional motor 16, a screw 17, a sliding plate 18, and a clamping frame 19. The bidirectional motor 16 is installed on the rear side of the mounting frame 4. The output shafts on both sides of the bidirectional motor 16 are connected to the screw 17 by welding. The mounting frame 4 has limiting grooves on the left and right sides. The sliding plate 18 is slidably connected to the mounting frame 4 through the limiting grooves. The bottom of the sliding plate 18 is slidably engaged with the mounting base 3. A clamping frame 19 is provided on the upper part of the side where the two sliding plates 18 are close to each other. The top of the clamping frame 19 has an opening and is hollow inside, which is used to collect the waste generated during the trimming process. The middle part of the side where the two clamping frames 19 are close to each other has a recess that is adapted to the core column 10 and the outer periphery of the food boot A, which is used to clamp the outer periphery of the food boot A and provide stable support for the operation of the trimming knife 15. The bidirectional motor 16 is electrically connected to the controller 2.

[0027] like Figure 5 , Figure 7 and Figure 8 As shown, it also includes an upper limit block 20 and a lower limit block 21. The upper part of the two sliding plates 18 on the side close to each other is connected to the two upper limit blocks 20 by bolts. The upper limit blocks 20 have elastic deformation capability to provide clearance space when the clamping frame 19 is installed or removed. The upper limit blocks 20 correspond to the upper two sides of the clamping frame 19. The lower part of the two sliding plates 18 on the side close to each other is connected to the two lower limit blocks 21 by bolts. The lower limit blocks 21 correspond to the lower two sides of the clamping frame 19.

[0028] like Figure 7 and Figure 8As shown, it also includes a fixing block 22, a pull rod 23, a locking block 24, and a spring 25. The fixing block 22 is connected to the sliding plate 18 below the lower limit block 21 by bolts. Multiple pull rods 23 pass through the fixing block 22 and are slidably connected to it. The upper end of the pull rod 23 is connected to the locking block 24 by bolts. The bottom of the clamping frame 19 has a slot that matches the shape of the locking block 24 at the position corresponding to the locking block 24. Multiple springs 25 are provided between the locking block 24 and the fixing block 22. The springs 25 are sleeved around the pull rod 23 to provide a reset elastic force.

[0029] When in use, place the food boot A to be trimmed on the positioning seat 7. Its front and rear sides are initially positioned by U-shaped limiting blocks. The controller 2 starts the first electric push rod 6, and its telescopic end pushes the positioning seat 7 to move backward along the vertical guide rail 5, so that the food boot A enters the working area on the upper part of the mounting seat 3 and the inner side of the mounting frame 4.

[0030] Subsequently, the controller 2 controls the second electric push rod 8 to move downwards, and its telescopic end drives the fixed plate 9 and the core column 10 to move downwards simultaneously. The trapezoidal guide block 11 at the bottom of the core column 10 is inserted into the closed opening at the top of the food boot A cylinder. The cylinder opening is gradually opened by the sloping structure that is wider at the top and narrower at the bottom, forming a stable trimming operation space.

[0031] After the food is fully extended, the controller 2 starts the bidirectional motor 16, and its two output shafts synchronously drive the screw 17 to rotate, driving the sliding plate 18 to slide towards each other along the limiting groove on the mounting frame 4. The sliding plate 18 drives the clamping frame 19 to move towards the center. The recessed part on the inner side of the clamping frame 19 is adapted to the outer periphery of the extended food shoe A and the shape of the core column 10, so as to achieve stable clamping of the food shoe A. The upper limit block 20 and the lower limit block 21 respectively limit and guide the upper and lower parts of the clamping frame 19 to ensure centering and stability during the clamping process.

[0032] After clamping is completed, controller 2 starts micro motor 14, and at the same time, electric circular guide rail 12 runs, driving slider 13 to move circumferentially around core column 10 along the circular path. Micro motor 14 drives trimming blade 15 to rotate at high speed. Under the drive of electric circular guide rail 12, trimming blade 15 continuously cuts along the top edge of food boot A, completing the edge trimming. Waste generated during the trimming process falls into the hollow cavity at the top of clamping frame 19 for centralized collection.

[0033] After the trimming is completed, each actuator resets in reverse order: the second electric push rod 8 moves upward, and the core column 10 and guide block 11 retract; the bidirectional motor 16 reverses, and the sliding plate 18 drives the clamping frame 19 to retract; the first electric push rod 6 retracts, the positioning seat 7 moves forward to reset, and the finished food shoe A is taken out.

[0034] If the clamping frame 19 needs to be replaced or maintained, the pull rod 23 can be manually pulled down to move the locking block 24 upward against the elastic force of the spring 25, so that it is disengaged from the locking groove at the bottom of the clamping frame 19, and the clamping frame 19 can be removed from the sliding plate 18. During installation, first place the clamping frame 19 on the sliding plate 18 and align its bottom locking groove with the locking block 24. Then pull down the pull rod 23 to make the locking block 24 move out of position. After releasing the pull rod 23, the locking block 24 is inserted into the locking groove under the elastic force of the spring 25, completing the quick locking.
