Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile parts, in particular to a device for machining brake calipers. BACKGROUND

[0002] The brake caliper is a core component of the automobile disc brake, and the brake caliper generates braking force by the interaction between the piston and the friction plate and the brake disc.

[0003] Figure 1 The local structure of the brake caliper is shown; with reference to Figure 1 As shown, the cylinder hole 11 of the brake caliper 10 has two important annular grooves, namely the rectangular groove 111 and the dustproof groove 112. When machining the two annular grooves, iron filings 113 are easily stuck in the annular grooves, and if not cleaned, it will cause the brake fluid to leak inside the brake caliper 10, causing safety accidents.

[0004] Currently, there are two ways to deal with the iron filings remaining in the rectangular groove 111 and the dustproof groove 112:

[0005] (1) Detection, if the rectangular groove 111 and the dustproof groove 112 are detected to have residual iron filings, the brake caliper 10 is determined as unqualified product, which will lead to high cost and affect the yield;

[0006] (2) Purging, but due to the electroplating process, the iron filings are adhered to the annular groove, and the purging force is limited, which cannot be completely removed.

[0007] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present application, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art. SUMMARY

[0008] Therefore, the present application provides a device for machining brake calipers, which can effectively remove the residual iron filings in the annular groove and improve the yield of the product.

[0009] According to one aspect of the present application, a device for machining brake calipers is provided, comprising: a support shaft fixed to a device bottom plate, the end of the support shaft being provided with a positioning core capable of extending into the cylinder hole of the brake caliper; a rotating sleeve rotatably sleeved on the outside of the support shaft; a scrap removing mechanism installed on the first end of the rotating sleeve close to the positioning core, the scrap removing mechanism having a scrap removing head capable of extending into the annular groove of the cylinder hole; a rotating drive mechanism supported on the device bottom plate and connected with the rotating sleeve, when the rotating drive mechanism drives the rotating sleeve to rotate, the scrap removing mechanism rotates with it, and the scrap removing head performs a scrap removing operation on the annular groove.

[0010] The device for machining brake calipers has a support shaft with a positioning core at the end, which can extend into the cylinder hole of the brake caliper and provide positioning support for the brake caliper. The debris removal mechanism is arranged close to the positioning core so that the debris removal head can extend into the annular groove of the cylinder hole. In addition, the debris removal mechanism is installed on a rotating sleeve, which is rotatably sleeved on the support shaft and driven to rotate by a rotating drive mechanism, so as to drive the debris removal head to rotate around the annular groove, scrape the remaining iron filings in the annular groove, effectively remove the debris, reduce the scrap cost of the brake caliper, and improve the processing yield of the brake caliper.

[0011] In some embodiments, the debris removal mechanism is radially slidably installed on the rotating sleeve; when the debris removal mechanism is retracted relative to the rotating sleeve, the debris removal head can extend into the cylinder hole; and when the debris removal mechanism is extended relative to the rotating sleeve, the debris removal head can extend into the annular groove.

[0012] The diameter of the cylinder hole is smaller than that of the annular groove. By radially slidably installing the debris removal mechanism on the rotating sleeve, the debris removal mechanism is retracted relative to the rotating sleeve when debris removal is needed, so that the debris removal head extends into the cylinder hole. Due to the positioning effect of the positioning core, the debris removal head is located at the annular groove of the cylinder hole in the axial direction. Then, the debris removal mechanism is extended relative to the rotating sleeve, so that the debris removal head extends into the annular groove.

[0013] In some embodiments, the device for machining brake calipers further comprises a telescopic drive mechanism supported on the device bottom plate and spaced apart from the debris removal mechanism; and an elastic return member arranged between the debris removal mechanism and the rotating sleeve. When the telescopic drive mechanism is extended, it can retract the debris removal mechanism relative to the rotating sleeve; and when the telescopic drive mechanism is retracted, the elastic return member can extend the debris removal mechanism relative to the rotating sleeve.

[0014] When the telescopic drive mechanism is extended, it retracts the debris removal mechanism relative to the rotating sleeve, so that the debris removal head can extend into the annular groove of the cylinder hole. When the telescopic drive mechanism is retracted, the debris removal mechanism extends relative to the rotating sleeve under the elastic return action of the elastic return member, so that the debris removal head extends into the annular groove to perform debris removal operation on the annular groove.

[0015] In some embodiments, the debris removal mechanism is slidably installed on the rotating sleeve by at least two cylindrical members; the elastic return member is sleeved on the cylindrical members; and / or the telescopic drive mechanism is in contact with the part of the debris removal mechanism located between the at least two cylindrical members and protruding radially.

[0016] The debris removing mechanism is slidably mounted on the rotating sleeve through at least two cylindrical members, which realizes sliding guide and avoids rotation; the elastic reset member is sleeved on the cylindrical member, which can realize stable elastic reset function and push the debris removing mechanism to extend relative to the rotating sleeve; the telescopic driving mechanism is in contact with the part of the debris removing mechanism which is located between the cylindrical members and protrudes radially, so as to push the debris removing mechanism to retract relative to the rotating sleeve without interference with the cylindrical member and other components.

[0017] In some embodiments, the debris removing mechanism comprises a sliding block mounted on the rotating sleeve and the debris removing head detachably inserted into the sliding block.

[0018] The debris removing mechanism is formed by the insertion of the sliding block and the debris removing head, which realizes the sliding and debris removing functions of the debris removing mechanism and facilitates the replacement of the debris removing head according to the brake caliper with different ring groove sizes, so as to improve the applicability and utilization of the device for machining brake calipers.

[0019] In some embodiments, a sensor for detecting iron filings is arranged at the debris removing head; wherein the rotating driving mechanism can be triggered when the sensor detects iron filings.

[0020] The sensor arranged at the debris removing head can detect whether there are iron filings in the ring groove when the debris removing head extends into the ring groove, and then decide whether the ring groove needs to be cleaned; in addition, the rotating driving mechanism can be automatically triggered when the sensor detects iron filings, so as to drive the debris removing head to clean the ring groove.

[0021] In some embodiments, the rotating driving mechanism is connected to the rotating sleeve through a transmission mechanism, and the transmission mechanism comprises two synchronous wheels respectively sleeved on the output shaft of the rotating driving mechanism and the outside of the rotating sleeve, and a synchronous belt connecting the two synchronous wheels.

[0022] The power of the rotating driving mechanism is transmitted to the rotating sleeve through the two synchronous wheels respectively sleeved on the output shaft of the rotating driving mechanism and the outside of the rotating sleeve, and the synchronous belt connecting the two synchronous wheels, so as to drive the rotating sleeve to rotate.

[0023] In some embodiments, the second end of the rotating sleeve away from the positioning core is supported on the device bottom plate through a bearing mechanism, and the bearing mechanism comprises a bearing seat fixedly arranged on the device bottom plate, a sunken table provided on the bearing seat abutting against the supporting shaft, and a ball bearing provided in the sunken table, wherein the outer ring of the ball bearing is in interference fit with the bearing seat, and the inner ring of the ball bearing is in interference fit with the second end of the rotating sleeve.

[0024] The rotating sleeve is supported by the bearing mechanism to ensure stable rotation of the rotating sleeve; wherein the bearing seat is provided with a sink to accommodate the ball bearing, facilitating interference fit of the outer ring of the ball bearing with the bearing seat and interference fit of the inner ring with the second end of the rotating sleeve, so as to support the rotating sleeve to rotate.

[0025] In some embodiments, the second end of the rotating sleeve is provided with a shoulder covering the ball bearing in the axial direction; and the bearing mechanism further comprises a bearing cover fixed to the bearing seat and covering the shoulder in the axial direction.

[0026] The shoulder of the rotating sleeve covers the ball bearing, and the bearing cover fixed to the bearing seat covers the shoulder, which limits the ball bearing and the second end of the rotating sleeve, avoiding disengagement of the rotating sleeve and the ball bearing from the bearing seat.

[0027] In some embodiments, the positioning core is detachably inserted into the support shaft.

[0028] Thus, the positioning core can be replaced according to the brake caliper with different cylinder hole sizes, so as to improve the applicability and utilization of the brake caliper processing device.

[0029] In some embodiments, the positioning core is interference fit with the cylinder hole when it extends into the cylinder hole.

[0030] Thus, the positioning core can stably position the brake caliper to ensure that the brake caliper remains stable during the chip removal operation.

[0031] In some embodiments, the brake caliper processing device further comprises a top rod which is liftable and is arranged in the support shaft, the positioning core is provided with a stepped inner wall, the top rod has a radially outwardly protruding top head, the stepped inner wall limits the top head, and a copper sleeve is sleeved on the end of the top head; a top lifting driving mechanism is connected with the top rod, and the top lifting driving mechanism can drive the top rod to lift up to drive the copper sleeve to be press-fitted into the end of the cylinder hole.

[0032] The top head of the top rod is limited by the stepped inner wall of the positioning core to avoid falling out of the support shaft; the end of the top head is sleeved with a copper sleeve, and when the top lifting driving mechanism drives the top rod to lift up, it drives the copper sleeve to be press-fitted into the end of the cylinder hole; thus, the brake caliper processing device can simultaneously realize the chip removal operation of the ring groove and the press-fitting operation of the copper sleeve, so as to improve the production efficiency and meet the requirements of efficient production.

[0033] In some embodiments, the end of the top rod away from the top head penetrates through the device bottom plate, and the top lifting driving mechanism is arranged on the back of the device bottom plate.

[0034] The jacking driving mechanism is arranged at the back of the device bottom plate, avoiding interference with the scrap removing mechanism, the rotating driving mechanism and other components arranged at the front of the device bottom plate.

[0035] The present application has at least the following advantages over the prior art:

[0036] The device for machining brake calipers of the present application has a support shaft with a positioning core at the end, which can extend into the cylinder hole of the brake caliper and simultaneously provide positioning and support for the brake caliper. The scrap removing mechanism is arranged close to the positioning core so that the scrap removing head can extend into the annular groove of the cylinder hole. In addition, the scrap removing mechanism is mounted on a rotating sleeve which is rotatably sleeved on the support shaft and driven to rotate by the rotating driving mechanism, so as to drive the scrap removing head to rotate around the annular groove, scrape the remaining iron filings in the annular groove with the scrap removing head, effectively remove the iron filings, reduce the scrap cost of the brake caliper, and improve the processing yield of the brake caliper.

[0050] It should be noted that the features of the embodiments of the present application and the features in different embodiments can be combined with each other without conflict.

[0051] Figure 2 Fig. 1 shows a structure of the device for machining brake calipers, Figure 3 Fig. 2 shows a structure diagram of the debris removing head of the debris removing mechanism in the embodiment of the present application; Figures 1 to 3 As shown in the drawings, the device for machining brake calipers provided by the embodiment of the present application comprises:

[0052] The support shaft 30 is fixed to the device bottom plate 20, and the end of the support shaft 30 is provided with a positioning core 33 capable of extending into the cylinder hole 11 of the brake caliper 10;

[0053] The rotating sleeve 40 is rotatably sleeved outside the support shaft 30;

[0054] The debris removal mechanism 50 is installed on the first end of the rotating sleeve 40 close to the positioning core 33, and the debris removal mechanism 50 has a debris removal head 55 capable of extending into the annular groove (including the rectangular groove 111 and the dustproof groove 112) of the cylinder hole 11.

[0055] The rotating drive mechanism 60 is supported on the device bottom plate 20 and connected with the rotating sleeve 40. When the rotating drive mechanism 60 drives the rotating sleeve 40 to rotate, the debris removal mechanism 50 rotates with it, and the debris removal head 55 performs the debris removal operation on the annular groove.

[0056] The above-mentioned brake caliper machining device can extend into the cylinder hole 11 of the brake caliper 10 through the support shaft 30 provided with the positioning core 33 at the end, and at the same time, it can play a role of positioning and supporting the brake caliper 10. In addition, the debris removal mechanism 50 is arranged close to the positioning core 33 so that the debris removal head 55 can extend into the annular groove of the cylinder hole 11. Furthermore, the debris removal mechanism 50 is installed on the rotating sleeve 40, the rotating sleeve 40 is rotatably sleeved outside the support shaft 30 (the rotating sleeve 40 and the support shaft 30 can be gap-fitted), and is driven to rotate by the rotating drive mechanism 60, which can drive the debris removal head 55 to rotate around the annular groove. The debris removal head 55 scrapes off the residual iron filings 113 in the annular groove (including the rectangular groove 111 and the dustproof groove 112), effectively removes the debris, reduces the scrap cost of the brake caliper 10, and improves the processing yield of the brake caliper 10.

[0057] Figure 4 The position relationship between the debris removal mechanism in the retracted state and the annular groove of the brake caliper is shown; in combination with Figures 1 to 4 As shown in some embodiments, the debris removal mechanism 50 is slidably installed on the rotating sleeve 40 along the radial direction X. When the debris removal mechanism 50 is retracted relative to the rotating sleeve 40 (i.e., the debris removal mechanism 50 approaches the rotating sleeve 40 along the radial direction X), the debris removal head 55 can extend into the cylinder hole 11. When the debris removal mechanism 50 is extended relative to the rotating sleeve 40 (i.e., the debris removal mechanism 50 is away from the rotating sleeve 40 along the radial direction X), the debris removal head 55 can extend into the annular groove (including the rectangular groove 111 and the dustproof groove 112).

[0058] The hole diameter of the cylinder hole 11 is smaller than the hole diameter of the annular groove. By slidably installing the debris removal mechanism 50 on the rotating sleeve 40 along the radial direction X, when the debris removal operation is needed, the debris removal mechanism 50 is first retracted relative to the rotating sleeve 40 so that the debris removal head 55 extends into the cylinder hole 11. And due to the positioning effect of the positioning core 33, at this time the debris removal head 55 is just located at the annular groove (including the rectangular groove 111 and the dustproof groove 112) of the cylinder hole 11 in the axial direction. Then the debris removal mechanism 50 is extended relative to the rotating sleeve 40 so that the debris removal head 55 extends into the annular groove (including the rectangular groove 111 and the dustproof groove 112).

[0059] In actual operation, the brake caliper 10 can be first sleeved on the positioning core 33 by manual operation, and then the telescopic drive mechanism 58 is triggered to make the debris removal head 55 extend into the annular groove.

[0060] Figure 5 This diagram shows enlarged structures of components such as the telescopic drive mechanism and the chip removal mechanism of the brake caliper machining device; combined with Figures 1 to 5 As shown, in some embodiments, the brake caliper processing apparatus further includes:

[0061] The telescopic drive mechanism 58 is supported on the device base plate 20 and is spaced apart from the chip removal mechanism 50.

[0062] The elastic reset element 52 is disposed between the chip removal mechanism 50 and the rotating sleeve 40;

[0063] When the telescopic drive mechanism 58 extends, it can push the chip removal mechanism 50 to retract relative to the rotating sleeve 40; when the telescopic drive mechanism 58 retracts, the elastic reset member 52 can push the chip removal mechanism 50 to extend relative to the rotating sleeve 40.

[0064] Specifically, the telescopic drive mechanism 58 can push the chip removal mechanism 50 through the drive rod 59. When the telescopic drive mechanism 58 extends along the first radial direction X1, it pushes the chip removal mechanism 50 to retract relative to the rotating sleeve 40, so that the chip removal head 55 can extend into the annular groove of the cylinder bore 11; when the telescopic drive mechanism 58 retracts along the second radial direction X2, the chip removal mechanism 50 extends relative to the rotating sleeve 40 under the elastic reset action of the elastic reset member 52, so that the chip removal head 55 extends into the annular groove (including the rectangular groove 111 and the dustproof groove 112) to perform chip removal operation on the annular groove.

[0065] In some embodiments, the chip removal mechanism 50 is slidably mounted on the rotating sleeve 40 via at least two cylindrical members 53; an elastic reset member 52 is sleeved on the cylindrical members 53; and / or, the telescopic drive mechanism 58 contacts and engages with the radially protruding portion 500 of the chip removal mechanism 50 located between at least two cylindrical members 53.

[0066] The chip removal mechanism 50 is slidably mounted on the rotating sleeve 40 via at least two cylindrical members 53, which serves to guide the sliding and prevent rotation. The elastic reset member 52 is sleeved on the cylindrical members 53, which can achieve a stable elastic reset and push the chip removal mechanism 50 to extend relative to the rotating sleeve 40. The telescopic drive mechanism 58 contacts and engages with the radially protruding part 500 of the chip removal mechanism 50 located between the cylindrical members 53, so as to push the chip removal mechanism 50 to retract relative to the rotating sleeve 40 without interfering with the cylindrical members 53 and other components.

[0067] In some specific examples, the cylindrical member 53 may be a height-equalizing screw, a pin, or other suitable cylindrical structure, and the elastic reset member 52 may be a spring or other suitable elastic reset structure.

[0068] Figure 6 The structure of the sliding block of the chip removal mechanism is shown.Figure 7 The structure of the cleaning head of the cleaning mechanism is shown; combined with Figures 1 to 7 As shown, in some embodiments, the chip removal mechanism 50 includes a sliding block 54 mounted on the rotating sleeve 40 and a chip removal head 55 detachably inserted into the sliding block 54.

[0069] The sliding block 54 can be provided with a slot 540, and the chip removal head 55 can be provided with a connector 550, which is detachably inserted into the slot 540. The chip removal mechanism 50 is formed by the insertion of the sliding block 54 and the chip removal head 55, which realizes both the sliding and chip removal functions of the chip removal mechanism 50, and also facilitates the replacement of the chip removal head 55 with a suitable one according to the different annular groove sizes of the brake caliper 10, thereby improving the applicability and utilization rate of the brake caliper machining device.

[0070] In some embodiments, a sensor (not specifically shown) for detecting iron filings is provided at the chip removal head 55; wherein, the rotary drive mechanism 60 can be triggered when the sensor detects iron filings.

[0071] By using a sensor located at the chip removal head 55, it is possible to detect whether iron filings 113 remain in the annular groove when the chip removal head 55 extends into the annular groove, and then decide whether to perform chip removal operation on the annular groove. In addition, when the sensor detects iron filings 113, it can automatically trigger the rotary drive mechanism 60 (for example, by using the electrical signal of the sensor detecting iron filings 113 to trigger the opening of the rotary drive mechanism 60) to automatically drive the chip removal head 55 to perform chip removal operation on the annular groove.

[0072] In some embodiments, the rotary drive mechanism 60 is connected to the rotary sleeve 40 via a transmission mechanism, which includes: two synchronous pulleys 62, which are respectively sleeved on the output shaft of the rotary drive mechanism 60 and the outside of the rotary sleeve 40; and a synchronous belt 63, which connects the two synchronous pulleys 62.

[0073] The rotary drive mechanism 60 can be a stepper motor or other suitable rotary mechanism. The power of the rotary drive mechanism 60 is transmitted to the rotary sleeve 40 through two synchronous pulleys 62 (the synchronous pulleys 62 and their corresponding shaft components can be fixed by set screws) respectively sleeved on the output shaft of the rotary drive mechanism 60 and the outside of the rotary sleeve 40, and a synchronous belt 63 connecting the two synchronous pulleys 62, so as to drive the rotary sleeve 40 to rotate.

[0074] In some embodiments, the second end of the rotating sleeve 40 away from the positioning core 33 is supported on the device base plate 20 by a bearing mechanism. The bearing mechanism includes: a bearing seat 72, which is fixedly mounted on the device base plate 20, and the bearing seat 72 is provided with a recess 720, which abuts against the support shaft 30; and a ball bearing 74, which is disposed in the recess 720, with the outer ring of the ball bearing 74 having an interference fit with the bearing seat 72 and the inner ring of the ball bearing 74 having an interference fit with the second end of the rotating sleeve 40.

[0075] The rotating sleeve 40 is supported by a bearing mechanism to ensure that the rotating sleeve 40 can rotate stably. The bearing housing 72 is provided with a recess 720, which can accommodate the ball bearing 74. This facilitates the interference fit between the outer ring of the ball bearing 74 and the bearing housing 72, and the interference fit between the inner ring of the ball bearing 74 and the second end of the rotating sleeve 40, so that the ball bearing 74 supports the rotation of the rotating sleeve 40.

[0076] In some embodiments, the second end of the rotating sleeve 40 is provided with a shoulder 44, which covers the ball bearing 74 in the axial direction; the bearing mechanism also includes a bearing cover 76, which is fixed to the bearing seat 72 and covers the shoulder 44 in the axial direction.

[0077] The ball bearing 74 is covered by the shoulder 44 of the rotating sleeve 40, and the shoulder 44 is covered by the bearing cover 76 fixed to the bearing housing 72. This limits the movement of the ball bearing 74 and the second end of the rotating sleeve 40, preventing the rotating sleeve 40 and the ball bearing 74 from detaching from the bearing housing 72.

[0078] The bearing cover 76 can be fixed to the bearing housing 72 using hexagonal screws 77 or other suitable connecting structures. The bearing housing 72 can be fixed to the base plate 20 using a transition plate 22. The bearing housing 72 and the transition plate 22, as well as the transition plate 22 and the base plate 20, can be fixed using hexagonal screws 77 or other suitable connecting structures. In addition, the support shaft 30 can also be fixed to the device base plate 20 using hexagonal screws 77 or other suitable connecting structures.

[0079] Furthermore, in some embodiments, the positioning core 33 is detachably inserted into the support shaft 30.

[0080] This facilitates the replacement of the corresponding positioning core 33 with brake calipers 10 that have different cylinder bore 11 sizes, thereby improving the applicability and utilization of the brake caliper machining device.

[0081] In some embodiments, when the positioning core 33 extends into the cylinder bore 11, it is interference-fitted with the cylinder bore 11.

[0082] In this way, the positioning core 33 can stably position and support the brake caliper 10, ensuring that the brake caliper 10 remains stable during the chip removal operation.

[0083] Figure 8 The diagram shows the structure of the brake caliper after the ring groove cleaning operation and the copper bushing press-fit operation; combined with... Figures 1 to 4 as well as Figure 8 As shown, in some embodiments, the brake caliper processing apparatus further includes:

[0084] The top rod 80 is vertically inserted into the support shaft 30. The positioning core 33 is provided with a stepped inner wall 330. The top rod 80 has a radially protruding top head 82. The stepped inner wall 330 limits the top head 82, and a copper sleeve 84 is fitted at the end of the top head 82.

[0085] The lifting drive mechanism 88 is connected to the push rod 80. The lifting drive mechanism 88 can drive the push rod 80 to lift, so as to press the copper sleeve 84 into the end of the cylinder bore 11.

[0086] The top head 82 of the push rod 80 is confined to the inner wall 330 of the step of the positioning core 33 to prevent the push rod 80 from falling out of the support shaft 30. The lifting drive mechanism 88 can be a cylinder or other suitable lifting mechanism. A copper sleeve 84 is fitted onto the end of the top head 82. When the lifting drive mechanism 88 drives the push rod 80 to lift, it causes the copper sleeve 84 to be pressed into the end of the cylinder bore 11. In this way, by using a brake caliper machining device, the chip removal operation of the annular groove (including the rectangular groove 111 and the dustproof groove 112) and the pressing operation of the copper sleeve 84 can be realized simultaneously to improve production efficiency and meet the requirements of high-efficiency production.

[0087] The copper sleeve 84 is an important component of the brake caliper 10. The brake caliper processing apparatus of this embodiment integrates the ring groove cleaning function and the copper sleeve pressing function, and can perform ring groove cleaning and copper sleeve pressing simultaneously or sequentially according to the processing requirements of the brake caliper 10.

[0088] In some embodiments, the end of the push rod 80 away from the top head 82 passes through the device base plate 20, and the lifting drive mechanism 88 is disposed on the back side of the device base plate 20. In this way, interference between the lifting drive mechanism 88 and components such as the chip removal mechanism 50 and the rotation drive mechanism 60 disposed on the front side of the device base plate 20 can be avoided.

[0089] In summary, the brake caliper processing apparatus of the present invention, through the cooperation of the support shaft 30, the rotating sleeve 40, the chip removal mechanism 50 and the rotating drive mechanism 60, can effectively remove chips from the annular groove (including the rectangular groove 111 and the dustproof groove 112) of the brake caliper 10, thereby reducing the scrap cost of the brake caliper 10 and improving the processing yield of the brake caliper 10.

[0090] The brake caliper processing apparatus of the present invention can also press the copper sleeve 84 into the end of the cylinder bore 11 through the cooperation of the push rod 80 and the lifting drive mechanism 88; thus, by integrating the ring groove chip removal function and the copper sleeve pressing function, the brake caliper processing apparatus of the present invention can simultaneously realize the ring groove chip removal operation and the copper sleeve 84 pressing operation, so as to improve production efficiency and meet the requirements of high-efficiency production.

[0091] Furthermore, the brake caliper processing device of the present invention has a simple overall structure, is easy to maintain and repair, and can greatly reduce the investment of production capital.

[0092] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
